Description

Hinge assembly for furniture

Technical Field

The utility model relates to a hinge assembly for furniture, in particular to a hinge assembly used between furniture components.

Background technique

At present, the structure of the existing hinge mainly includes a hinge head, a hinge arm and a base. During installation, the hinge head and the base are installed on the cabinet door and the cabinet body respectively. Since the hinge itself has a single structure for adjusting the installation position and it is difficult to meet the use requirements, the installation accuracy and position accuracy of the existing hinge are high. When the installation position deviates, the cabinet door and the cabinet body cannot be installed at the predetermined position, making the installation difficult, extending the working cycle and reducing the working efficiency. For this reason, some hinges are provided with an adjustment device, and the hinge arm can achieve the height adjustment in the up-down direction or the front-back direction adjustment or the left-right direction adjustment relative to the base through the adjustment device. However, the process of adjusting the height of the hinge arm relative to the base in the up-down direction and in the left-right direction affects each other. For example, the height adjustment screw of the adjustment device can only adjust the front end of the base upward or downward. When the front end of the base is adjusted upward to the specified position, the front end of the base tilts toward the rear end and forms an angle with the hinge arm. It can also be understood that during the adjustment of the height adjustment screw, the angle between the base and the hinge arm changes, so it is easy for the cabinet door to not be closed in place or closed smoothly relative to the cabinet body, such as there is a gap between the side of the closed cabinet door and the cabinet body. Therefore, it is necessary to adjust the front and back adjustment screws of the base and the hinge arm to install the cabinet door and the cabinet body to the predetermined position. This makes it easy to make wrong height adjustments and front and back adjustments of the base and the hinge arm, and the adjustment is difficult.

In addition, the Chinese patent announcement number CN204691509U discloses a "buffer hinge with a parallel adjustment device", which includes a hinge cup, a swing arm, a hinge seat and a base assembly. The hinge cup, the swing arm and the hinge seat are hinged in sequence. The base assembly is installed on the hinge seat. The hinge seat is provided with a height adjustment assembly that can control the parallel movement height of the base assembly relative to the hinge seat as a whole. The height adjustment assembly passes through the hinge seat and is snapped onto the base assembly. Specifically, the height adjustment assembly includes a first height adjustment screw and a second height adjustment screw. The first height adjustment screw and the second height adjustment screw are respectively installed on the hinge seat front and back. By matching the structures of the first height adjustment screw and the second height adjustment screw of the height adjustment assembly, the entire hinge seat can be moved horizontally upward or downward to adjust the height, ensuring that the hinge seat can smoothly adjust the front and rear installation position relative to the base assembly on the horizontal plane. However, firstly, the height adjustment of the hinge seat needs to be achieved by means of the first height adjustment screw and the second height adjustment screw, and the adjustment process is cumbersome and difficult to adjust; generally, the operator adjusts one of the adjustment screws first and then the other adjustment screw. During the adjustment process, the base assembly actually rotates and swings back and forth relative to the hinge seat, and the base assembly is not kept level relative to the hinge seat during the entire adjustment process; secondly, when adjusting the height of the hinge seat, the front and rear adjustment screws need to be operated, that is, the height adjustment screw cannot be adjusted alone to complete the height adjustment, and the height adjustment screw and the front and rear adjustment screws affect each other during the adjustment process; thirdly, when adjusting the height of the hinge seat, the front and rear adjustment screws on the hinge seat need to be loosened first, which makes the hinge seat easy to move incorrectly in the front and rear directions, and the position shifts in the front and rear directions, increasing the difficulty of adjustment, thereby making the height adjustment of the hinge seat more troublesome; in addition, this solution does not produce a positive effect while increasing the adjustment steps.

For another example, the "Door Hinge Arm with Quick Adjustment and Installation Function" disclosed in Chinese Patent Publication No. CN10701023A includes: an inner arm and an outer arm, an adjustment mechanism and a movable adjustment device are provided between the inner arm and the outer arm, the adjustment mechanism is used to adjust the tilt angle between the outer arm and the inner arm; the movable adjustment device is used to automatically move the outer arm forward and backward on the inner arm when the tilt angle between the outer arm and the inner arm changes, so that the outer arm forms a relative movement between the inner arm and the inner arm, and the installation adjustment hinge arm for tilting and adjusting the door installation position. The door hinge can be adjusted by moving the adjustment device to achieve quick adjustment of the door installation position. However, the adjustment mechanism changes the tilt angle between the outer arm and the inner arm during the adjustment process, thereby changing the minimum closing angle and maximum opening angle of the hinge cup (hinge head) relative to the base, that is, changing the closing angle and opening angle of the door on the furniture, affecting the user's door opening and closing experience.

The hinges in the prior art, as well as the "Buffering Hinge with Parallel Adjustment Device" disclosed in Chinese Patent Publication No. CN204691509U and the "Door Hinge Arm with Quick Adjustment and Installation Function" disclosed in Chinese Patent Publication No. CN10701023A, have technical problems as described in the background technology.

Example 1

As shown in Figures 1 to 63, this embodiment 1 discloses a hinge assembly for furniture, including a first main body 1, a hinge head 2 and a base device 3, the hinge head 2 is rotatably connected to the first main body 1, and the hinge head 2 is used to connect the second component 200; the base device 3 is used to connect the first component 100; the base device 3 includes at least one first adjustment component 31 and at least one second adjustment component 32; wherein, the first adjustment component 31 is provided with at least one first adjustment portion 33, when the first adjustment portion 33 is adjusted alone, the first main body 1 can be translated and lifted only in the up and down directions relative to the first adjustment component 31, so that the first main body 1 can be translated and lifted only in the up and down directions relative to at least a part of the base device 3; the second adjustment component 32 is provided with a second adjustment portion 34, when the second adjustment portion 34 is adjusted alone, the first main body 1 can be moved only in the front and rear directions relative to at least a part of the base device 3.

The first component 100 and the second component 200 can be component panels of furniture products, and the materials can be wood, plastic, metal or other synthetic materials. The first component 100 can be, for example, a cabinet door, and the second component 200 can be, for example, a cabinet side panel of the cabinet. The first component 100 and the second component 200 can achieve relative rotation through the hinge assembly of this embodiment 1.

It can be understood that when the first adjustment part 33 is adjusted alone, the first body 1 is translated and lifted relative to the first adjustment component 31 only in the up-down direction (the up-down direction can usually be the height direction), that is, in the up-down direction, the height distances moved by each part of the first body 1 relative to the base device 3 in a unit time period are the same, so that the first body 1 will not tilt or move relative to the first adjustment component 31 and/or the second adjustment component 32 in the left-right direction or the front-back direction, thereby ensuring that the first body 1 has only a change in the degree of freedom in the up-down direction, and the position adjustment of the first body 1 relative to the base device 3 in the up-down direction is achieved, so that the position adjustment of the second component 200 relative to the first component 100 in the up-down direction is achieved. When the second adjustment part 34 is adjusted alone, at least a part of the first body 1 moves relative to the base device 3 only in the front-back direction, that is, in the front-back direction, the front-back distances moved by each part of the first body 1 relative to the base device 3 in a unit time period are the same, so that the first body 1 will not move relative to the base device 3 in the up-down direction or the left-right direction, thereby ensuring that the first body 1 has only a change in the degree of freedom in the front-back direction, and the position adjustment of the first body 1 relative to the base device 3 in the front-back direction is achieved. The first adjusting part 33 is used to adjust the first main body 1 to move horizontally and vertically relative to the base device 3, and the second adjusting part 34 is used to adjust the first main body 1 to move forward and backward relative to the base device 3, ensuring that the first main body 1 does not affect or interfere with each other during the up and down adjustment and forward and backward adjustment processes, reducing the difficulty of adjustment and improving the accuracy and convenience of adjusting the position of the cabinet door relative to the cabinet body.

It should be noted that the term "independent adjustment" generally describes that when the first adjustment portion 33 is adjusted, the first body 1 moves only in the up-down direction relative to the base device 3, and when the second adjustment portion 34 is adjusted, the first body 1 moves only in the front-back direction relative to the base device 3;

It also indicates that when the first adjusting portion 33 is adjusted, the first component 100 and the second component 200 will not be displaced in other directions except the up-down direction relative to the connection surface of the bottom mounting device 3; or, when the second adjusting portion 34 is adjusted, the first component 100 and the second component 200 will not be displaced in other directions except the front-back direction relative to the connection surface of the bottom mounting device 3;

It also shows that when adjusting the up-down direction of the first main body 1 relative to the base device 3, it is only necessary to adjust the first adjustment part 33 without adjusting the second adjustment part 34; or when adjusting the front-back direction of the first main body 1 relative to the base device 3, it is only necessary to adjust the second adjustment part 34 without adjusting the first adjustment part 33.

In addition, "the first body 1 will not tilt or move in the left-right direction or the front-to-back direction relative to the first adjustment component 31 and/or the second adjustment component 32" or "the first body 1 will not move in the up-down direction or the left-right direction relative to the base device 3" is a description method for describing the relativity of the front-to-back and up-down positions, and does not mean that there must be absolutely no errors or deviations; in actual production and installation, the dimensions of components often deviate. For example, when the first adjustment component 31 and the first body 1 or the second adjustment component 32 are adjusted up and down, and one end point on the first adjustment component 31 and the other end point on the first body 1 or the second adjustment component 32 are displaced within 15 degrees in the front-to-back or left-to-right direction due to adjustment, we still believe that this is a production and installation error and is still within the protection scope of this patent; the same applies to the adjustment process of the second adjustment component 32.

It should also be noted that, for example, as shown in Figures 1 to 3, the up-down direction of the hinge assembly of this embodiment 1 refers to the direction in which the side surface where the base device 3 is connected to the first component 100 faces the base device 3. When the first component 100 is a cabinet side panel and the second component 200 is a cabinet door, the up-down direction of the hinge assembly is the direction in which the cabinet door is adjusted left and right relative to the cabinet body (i.e., the left'right' direction in Figure 2 or Figure 3). The front-to-back direction of the hinge assembly refers to the direction in which the hinge head 2 faces the first body 1. When the first component 100 is a cabinet side panel and the second component 200 is a cabinet door, the front-to-back direction of the hinge assembly is the direction in which the cabinet door is adjusted front and back relative to the cabinet body. The left-to-right direction of the hinge assembly refers to a direction that is perpendicular to both the up-down direction and the front-to-back direction. When the first component 100 is a cabinet side panel and the second component 200 is a cabinet door, the left-to-right direction of the hinge assembly is the direction in which the cabinet door is adjusted up and down relative to the cabinet body.

This embodiment 1 does not limit the positional relationship between the first body 1, the first adjustment component 31 and the second adjustment component 32. In some embodiments, as shown in Figures 4 to 40, Figures 56 to 61, at least a portion of the first body 1 is located above the base device 3, and the first body 1 and the first adjustment component 31 or the second adjustment component 32 are connected from top to bottom, for example, the first body 1, the first adjustment component 31 and the second adjustment component 32 are arranged in sequence from top to bottom, or the first body 1, the second adjustment component 32 and the first adjustment component 31 are arranged in sequence from top to bottom. In some other embodiments, as shown in Figures 41 to 46, Figures 50 to 52, at least a portion of the base device 3 is located above the first body 1, and the first adjustment component 31 or the second adjustment component 32 and the first body 1 are connected from top to bottom, for example, the first adjustment component 31, the second adjustment component 32 and the first body 1 are arranged in sequence from top to bottom, or the second adjustment component 32, the first adjustment component 31 and the first body 1 are arranged in sequence from top to bottom. In some other embodiments, as shown in Figures 47 to 49 and Figures 53 to 55, at least a portion of the base device 3 is located on the side of the first main body 1, and the first adjustment component 31 or the second adjustment component 32 is connected to the first main body 1 in the left-right direction or the right-left direction. For example, the first adjustment component 31, the second adjustment component 32 and the first main body 1 are arranged in sequence from left to right, or the second adjustment component 32, the first adjustment component 31 and the first main body 1 are arranged in sequence from left to right.

In some embodiments, a first positioning portion 4 is formed on the first adjustment component 31, and a second positioning portion 5 that cooperates with the first positioning portion 4 is formed on the first body 1 and/or the second adjustment component 32. The first positioning portion 4 and the second positioning portion 5 cooperate with each other to limit the freedom of the first body 1 or the second adjustment component 32 relative to the first adjustment component 31 in the front-to-back direction and the left-to-right direction, so that the first body 1 can be translated and lifted relative to the first adjustment component 31 in the up-down direction. For example, the second positioning portion 5 can be located on the first body 1, and the first adjustment component 31 and the first body 1 can limit the freedom of the first body 1 in the front-to-back direction and the left-to-right direction relative to the first adjustment component 31 through the cooperation of the first positioning portion 4 and the second positioning portion 5, so as to ensure that when the first adjustment portion 33 is adjusted alone, the first body 1 can be translated and lifted relative to the first adjustment component 31 only in the up-to-down direction. For another example, the second positioning portion 5 can be located on the second adjusting component 32. The first adjusting component 31 and the second adjusting component 32 limit the freedom of the second adjusting component 32 in the front-to-back direction and the left-to-right direction relative to the first adjusting component 31 through the cooperation between the first positioning portion 4 and the second positioning portion 5, thereby ensuring that when the first adjusting portion 33 is adjusted alone, the second adjusting component 32 can only be translated and lifted along the up-and-down direction relative to the first adjusting component 31. In this embodiment, the second adjusting component 32 is connected to the first main body 1, so that the first main body 1 can only be translated and lifted along the up-and-down direction relative to the first adjusting component 31.

Furthermore, in some embodiments, in order to make the first positioning portion 4 and the second positioning portion 5 cooperate to limit the freedom of the first main body 1 or the second adjusting component 32 relative to the first adjusting component 31 along the front-to-back direction and the left-to-right direction, the side surfaces of the first positioning portion 4 along the front-to-back direction and the left-to-right direction and the side surfaces of the second positioning portion 5 along the front-to-back direction and the left-to-right direction correspond one by one, for example, by abutting or fitting, the position cooperation is carried out to limit the freedom of the first main body 1 or the second adjusting component 32 relative to the first adjusting component 31 along the front-to-back direction and the left-to-right direction, so that when the first adjusting portion 33 is driven alone, the first main body 1 can only be translated and lifted along the up-and-down direction relative to the first adjusting component 31.

Further, in some embodiments, as shown in FIGS. 25 to 28 , the first positioning portion 4 includes a first adjusting portion 33 and a first abutting portion 42, and the second positioning portion 5 includes a stabilizing portion 51 and a second abutting portion 52. The first adjusting portion 33 is cylindrical, and the first adjusting portion 33 is rotatably disposed on the stabilizing portion 51. For example, the first adjusting portion 33 is rotatably disposed on the stabilizing portion 51 by riveting or concave-convex fitting or screw fitting, so that the first adjusting portion 33 becomes a part of the first body 1 or the second adjusting component 32, and the first adjusting portion 33 rotates relative to the first body 1 or the second adjusting component 32; the first adjusting portion 33 is rotatable along the side and along the front-back direction and the left-right direction The side surfaces of the stabilizing portion 51 along the front-to-back direction and the left-to-right direction are matched one by one, for example, by abutting or fitting to limit the freedom of the first main body 1 or the second adjustment component 32 relative to the first adjustment component 31 along the front-to-back direction and the left-to-right direction; the first abutting portion 42 and the second abutting portion 52 abut against each other to limit the first adjustment portion 33 driving other components of the first adjustment component 31 to rotate relative to the first main body 1, or the second adjustment component 32 to rotate relative to the first adjustment component 31 when the first adjustment portion 33 is rotating, to ensure that only the first adjustment portion 33 is rotating, so that the first main body 1 can only be translated and lifted along the up and down directions relative to the first adjustment component 31.

In some embodiments, as shown in Figures 56 to 59, the first adjustment component 31 includes a first left side panel 311 and/or a first right side panel 312, and the first body 1 or the second adjustment component 32 includes a second left side panel 61 and/or a second right side panel 62; the first left side panel 311 and/or the first right side panel 312 are provided with at least one first folding portion (not shown in the figure), and the first positioning portion 4 includes a first folding portion; one end of the first folding portion is connected to the first left side panel 311, one of the left and right side surfaces of the first left side panel 311 is in close contact with one of the left and right side surfaces of the second left side panel 61, and the first folding portion passes over the second left side panel 61 and is in close contact with The other side of the second left side plate 61 abuts against each other, and the second left side plate 61 and the first folding portion cooperate with each other to limit the second left side plate 61 from moving in at least one direction of the left-right direction and the front-back direction; and/or, one end of the first folding portion is connected to the first right side plate 312, one of the left and right side surfaces of the first right side plate 312 and one of the left and right side surfaces of the second right side plate 62 are tightly attached, the first folding portion passes over the second right side plate 62 and abuts against the other side surface of the second right side plate 62, and the second right side plate 62 and the first folding portion cooperate with each other to limit the second right side plate 62 from moving in at least one direction of the left-right direction and the front-back direction. Among them, the position of the first left side plate 311 corresponds to the position of the second left side plate 61, and the position of the first right side plate 312 corresponds to the position of the second right side plate 62. For example, when the first adjustment component 31 includes the first left side plate 311, the second adjustment component 32 includes the second left side plate 61, and the first left side plate 311 and the second left side plate 61 abut against each other, and at the same time, the second left side plate 61 and the first folding portion cooperate with each other to limit the movement of the second left side plate 61 in at least one direction of the left and right direction and the front and back direction, thereby limiting the freedom of the first main body 1 or the second adjustment component 32 relative to the first adjustment component 31 in the front and back direction and/or the left and right direction, so that the first main body 1 can only be translated and lifted along the up and down direction relative to the first adjustment component 31.

The first folding portion may be, for example, a columnar structure, and one end of the first folding portion is plugged into the first left side plate 311 or the first right side plate 312. The first folding portion may be, for example, a convex or convex point or convex block structure, and one end of the first folding portion may form an integrated structure with the first left side plate 311 or the first right side plate 312. The number of first folding portions may be one or more, for example, the number of first folding portions is at least two, and at least two first folding portions respectively limit the movement of the first adjustment component 31 relative to the first body 1 or the second adjustment component 32 in the front-to-back direction. For example, there are two first folding portions respectively located at the two ends of the first left side plate 311 or the first right side plate 312 in the front-to-back direction, and the two first folding portions respectively cooperate with the second left side plate 61 or the second right side plate 62 to abut or fit each other, thereby limiting the movement of the first adjustment component 31 relative to the first body 1 or the second adjustment component 32 in the front-to-back direction.

In some other embodiments, as shown in Figures 56 to 59, the first adjustment component 31 includes a first left side panel 311 and/or a first right side panel 312, the first body 1 or the second adjustment component 32 includes a second left side panel 61 and/or a second right side panel 62; the second left side panel 61 and/or the second right side panel 62 is provided with at least one second folding portion 7, and the second positioning portion 5 includes a second folding portion 7; one end of the second folding portion 7 is connected to the second left side panel 61, one of the left and right side surfaces of the second left side panel 61 is tightly attached to one of the left and right side surfaces of the first left side panel 311, and the second folding portion 7 passes over the first left side panel 311 and is connected to the first left side panel 3 The first left side panel 311 and the second folding portion 7 are in contact with each other on the other side of the first right side panel 312, and the first left side panel 311 and the second folding portion 7 cooperate with each other to limit the first left side panel 311 from moving in at least one direction of the left-right direction and the front-back direction; and/or, one end of the second folding portion 7 is connected to the second right side panel 62, one of the left and right side surfaces of the second right side panel 62 is in close contact with one of the left and right side surfaces of the first right side panel 312, the second folding portion 7 passes over the first right side panel 312 and abuts against the other side surface of the first right side panel 312, and the first right side panel 312 and the second folding portion 7 cooperate with each other to limit the first right side panel 312 from moving in at least one direction of the left-right direction and the front-back direction. The structure and principle of the second folding portion 7 are the same as those of the first folding portion, and the detailed description is omitted here.

The number of the second folding parts 7 can be one or more, for example, the number of the second folding parts 7 is at least two, and at least two second folding parts 7 respectively limit the first adjustment part 33 and the first adjustment component 31 to move relative to the first body 1 or the second adjustment component 32 and the second adjustment part 34 along the front-to-back direction. For example, there are two second folding parts 7 respectively located at the two ends of the second left plate 61 or the second right plate 62 along the front-to-back direction, and the two second folding parts 7 respectively cooperate with the first left plate 311 or the first right plate 312 to abut or fit each other, thereby limiting the first adjustment component 31 to move relative to the first body 1 or the second adjustment component 32 along the front-to-back direction.

In some embodiments, as shown in FIGS. 4 to 33, 53 to 57, and 60 to 61, the second adjustment component 32 is connected to the first adjustment component 31, and the first adjustment component 31 is connected to the first body 1. This embodiment does not limit the positional relationship between the first body 1, the first adjustment component 31, and the second adjustment component 32, as long as the first body 1 can achieve translation and lifting only in the up-down direction relative to the first adjustment component 31 after adjusting the first adjustment part 33 alone. For example, the first body 1, the first adjustment component 31, and the second adjustment component 32 are connected in sequence from top to bottom, or for example, the first body 1 and the first adjustment component 31 are connected in sequence from top to bottom, and the first adjustment component 31 is located inside the second adjustment component 32, or for example, the second adjustment component 32, the first adjustment component 31, and the first body 1 are connected in sequence. By adjusting the first adjustment part 33 alone, the first body 1 can achieve translation and lifting only in the up-down direction relative to the first adjustment component 31.

Furthermore, in some embodiments, as shown in Figures 4 to 21, the second adjustment component 32 also includes a connecting part 325, and the connecting part 325 can be composed of one component or at least two components connected to each other in a detachable or non-detachable manner, and there is no limitation here. At least a portion of the connecting part 325 is fixedly connected to the first component 100, for example, the connecting part 325 is fastened to the first component 100 by bolts or screws; the first adjustment component 31 includes a fourth main body 314; the second adjustment part 34 connects the connecting part 325 and the fourth main body 314, and when the second adjustment part 34 is adjusted alone, the fourth main body 314 can move in the front and rear directions relative to the connecting part 325. Among them, a part of the second adjustment part 34 can be, for example, an eccentric piece or a sheet-like body in the shape of a Loehler triangle, and another part of the second adjustment part 34 can be rotatably arranged on the connecting part 325. The fourth main body 314 is formed with a matching part. During the rotation of the second adjustment part 34 relative to the connecting part 325, the fourth main body 314 is driven to slide relative to the connecting part 325 along the front-to-back direction, so that the fourth main body 314 moves relative to the connecting part 325 along the front-to-back direction. For example, the second adjustment part 34 is a fastener with external threads, and a slide groove extending along the front-to-back direction is formed on the fourth main body 314. The second adjustment part 34 passes through the slide groove and is threadedly connected to the connecting part 325. When the second adjustment part 34 and the fourth main body 314 are relatively loosened, the fourth main body 314 and the connecting part 325 can move along the front-to-back direction.

In some embodiments, the first adjustment portion 33 connects the fourth body 314 and the first body 1. When the first adjustment portion 33 is adjusted alone, the first body 1 can be translated and lifted only in the up and down directions relative to the fourth body 314, so that the first body 1 can be translated and lifted only in the up and down directions relative to the connecting part 325, thereby enabling the first body 1 to be translated and lifted only in the up and down directions relative to at least a portion of the base device 3.

Specifically, in some embodiments, the first adjusting portion 33 is a cylindrical structure and at least a portion of its outer wall or inner wall is a threaded structure, one end of the first adjusting portion 33 is threadedly connected to the first body 1, and the other end of the first adjusting portion 33 is connected to the fourth body 314, or one end of the first adjusting portion 33 is threadedly connected to the fourth body 314, and the other end of the first adjusting portion 33 is connected to the first body 1; when the first adjusting portion 33 is driven to rotate relative to the fourth body 314, the first body 1 can only be translated and lifted along the up-down direction relative to the fourth body 314, so that the first body 1 can only be translated and lifted along the up-down direction relative to the connecting component 325. Among them, the first adjusting portion 33, for example, is matched one-to-one with the side surfaces of the above-mentioned stabilizing portion 51 in the front-to-back direction and the left-to-right direction to limit the freedom of the first body 1 or the second adjusting component 32 relative to the first adjusting component 31 in the front-to-back direction and the left-to-right direction.

In some embodiments, the first body 1 includes a connecting plate 11, a left side plate 12 and a right side plate 13, and the connecting plate 11, the left side plate 12 and the right side plate 13 are enclosed to form a mounting groove 14, wherein the connecting plate 11, the left side plate 12 and the right side plate 13 can form an integrated structure by a bending process or a casting process; at least a portion of the fourth body 314 is arranged in the mounting groove 14 or at least a portion of the fourth body 314 is arranged below the first body 1, at least a portion of the connecting component 325 is arranged in the mounting groove 14 or at least a portion of the connecting component 325 is arranged below the fourth body 314, and at least one of the left side and the right side of the fourth body 314 is tightly attached to an outer side surface or an inner side surface of the mounting groove 14, so that in the process of adjusting the first adjustment part 33 alone, the left side or the right side of the fourth body 314 is mutually limited with the outer side surface or the inner side surface of the mounting groove 14 to prevent the first body 1 from moving in the left and right directions relative to the fourth body 314 or the connecting component 325, so that the first body 1 can only be translated and lifted along the up and down directions relative to the connecting component 325.

In some embodiments, the first main body 1 includes a connecting plate 11, a left side plate 12 and a right side plate 13, and the connecting plate 11, the left side plate 12 and the right side plate 13 are enclosed to form a mounting groove 14; at least a portion of the connecting component 325 can be located in the mounting groove 14 or at least a portion is arranged below the first main body 1; and at least one of the left side and the right side surfaces of the connecting component 325 is tightly attached to an outer side surface or an inner side surface of the mounting groove 14, so that in the process of adjusting the first adjustment part 33 alone, the left side or the right side surface of the connecting component 325 is limited to the outer side surface or the inner side surface of the mounting groove 14 to prevent the first main body 1 from moving in the left and right directions relative to the connecting component 325, so that the first main body 1 can only be translated and lifted along the up and down directions relative to the connecting component 325.

In some embodiments, as shown in Figures 34 to 52, the first adjustment component 31 and the second adjustment component 32 are connected, and the second adjustment component 32 is connected to the first body 1. This embodiment does not limit the positional relationship between the first body 1, the first adjustment component 31 and the second adjustment component 32. The first body 1 is connected to the first adjustment component 31 through the second adjustment component 32. When the first adjustment part 33 is adjusted alone, the first body 1 can only be translated and lifted along the up and down direction relative to the first adjustment component 31.

Furthermore, in some embodiments, as shown in Figures 36 to 38, the second adjustment component 32 also includes a fifth body 324, and the first adjustment component 31 also includes a fourth body 314, and at least a portion of the fourth body 314 can be used to be fixedly connected to the first component 100, for example, the fourth body 314 is fastened to the first component 100 by bolts or screws; the fifth body 324 can be translated and lifted in the up and down directions relative to the fourth body 314, so that the first body 1 can be translated and lifted in the up and down directions relative to the fourth body 314, so that the first body 1 can be translated and lifted only in the up and down directions relative to at least a portion of the base device 3.

In some embodiments, when the second adjustment portion 34 is adjusted alone, the first body 1 can move only in the front-to-back direction relative to the fifth body 324 , and thus the first body 1 can move only in the front-to-back direction relative to the fourth body 314 .

Specifically, in some embodiments, the first adjusting portion 33 is a cylindrical structure and at least a portion of its outer wall or inner wall is a threaded structure, one end of the first adjusting portion 33 is threadedly connected to the fifth body 324, and the other end of the first adjusting portion 33 is connected to the fourth body 314, or one end of the first adjusting portion 33 is threadedly connected to the fourth body 314, and the other end of the first adjusting portion 33 is connected to the fifth body 324; when the first adjusting portion 33 is driven to rotate relative to the fourth body 314, the fifth body 324 can be translated and lifted relative to the fourth body 314 in the up-down direction, so that the first body 1 can be translated and lifted relative to the fourth body 314 in the up-down direction, thereby enabling the first body 1 to be translated and lifted relative to at least a portion of the base device 3 only in the up-down direction. Among them, the first adjusting portion 33, for example, is matched one-to-one with the side surfaces of the above-mentioned stabilizing portion 51 in the front-to-back direction and the left-to-right direction to limit the freedom of the first body 1 or the second adjusting component 32 relative to the first adjusting component 31 in the front-to-back direction and the left-to-right direction.

In some embodiments, as shown in FIGS. 20 to 21, 34 to 35, 38 to 40, and 51 to 52, the first body 1, and/or the first adjustment component 31, and/or the second adjustment component 32, and/or between the first body 1 and the second adjustment component 32, and/or between the first adjustment component 31 and the second adjustment component 32, and/or between the first adjustment component 31 and the first body 1, are connected or separated by a disassembly device 10. The disassembly device 10 may be a sliding disassembly device or a pressing disassembly device or other forms of disassembly devices, wherein the specific structure of the disassembly device 10 is a conventional structure in the technical field, for example, the pressing disassembly device 10 includes a button and a spring, one end of the button is provided with a buckle, and the other end of the button is pressed to control the buckle connection or release, thereby achieving connection or separation between the above components. The spring is used to drive the pressing member to automatically reset.

Furthermore, in some embodiments, the disassembly device 10 is a push-type disassembly device, and an operation hole 16 is formed on the first body 1, and the operation hole 16 is used for external force to control the connection or separation state of the push-type disassembly device. The position of the operation hole 16 is set accordingly according to the position of the push-type disassembly device, for example, the operation hole 16 can be located at the top or left side or right side of the first body 1. The user uses an external tool such as a screwdriver to pass through the operation hole 16 and act on the push-type disassembly device, and adjusts the working state of the push-type disassembly device to achieve the connection or separation between the above components.

In some embodiments, as shown in FIG. 32 , the base device 3 includes a third adjustment component 35, which is disposed inside the first body 1, and/or inside the first adjustment component 31, and/or inside the second adjustment component 32, and/or between the first body 1 and the second adjustment component 32, and/or between the first adjustment component 31 and the second adjustment component 32, and/or between the first adjustment component 31 and the first body 1. The third adjustment component 35 includes a third adjustment portion. When the third adjustment portion is adjusted alone, the first body 1 can move in the left-right direction relative to at least a portion of the base device 3. The structure of the third adjustment portion is the same or similar to that of the second adjustment portion 34 of the present embodiment 1. For details, please refer to the description of the second adjustment portion 34, which is omitted here. By adding the third adjustment component 35 and the third adjustment portion, the three-dimensional adjustment of the hinge assembly of the present embodiment 1 is achieved, and the convenience of adjustment and the accuracy of the installation position are improved.

During use, the first member 100 may be subjected to its own gravity or the gravity of the second member 200 or after long-term frequent use, and the base device 3 may be offset in the left-right direction on the first member 100, resulting in position offset of the hinge assembly. In order to solve this technical problem, as shown in Figures 60 to 63, in some embodiments, the base device 3 includes at least one adjustment hole 36, which is used for a fastener to fix the base device 3 on the first member 100, and when the fastener is in a preset state, the base device 3 can move in the left-right direction relative to the fastener; the upper surface of the peripheral wall of the adjustment hole 36 has a transverse stripe 361 extending forward and backward, and when the fastener is in a locked state, the transverse stripe 361 is used to prevent the base device 3 from moving in the left-right direction relative to the fastener; and/or, the base device 3 has a protrusion 362 extending downward, and when the fastener is in a locked state, the protrusion 362 and the first member 100 are locked to prevent the base device 3 from moving in the left-right direction relative to the fastener. The number of the adjustment holes 36 is one or more, for example, two adjustment holes 36 are respectively arranged at the two ends of the base device 3 along the front-back direction. The transverse stripe 361 forms an integrated structure with the base device 3, which is specifically prepared by casting, cutting or mold manufacturing. The transverse stripe 361 can be composed of a plurality of convex ribs, bosses or convex strips. The fastener is, for example, a screw or a bolt. When the fastener locks the base device 3 on the first component 100, the head of the fastener and the transverse stripe 361 cooperate with each other to abut against each other, and the transverse stripe 361 is used to generate a resistance to the fastener to prevent movement in the left and right directions, thereby limiting the movement of the base device 3 on the first component 100 in the left and right directions. Alternatively, when the fastener is locked on the first component 100, at least a portion of the protrusion 362 is embedded in the interior of the first component 100, so that the protrusion 362 and the first component 100 bite each other, thereby limiting the movement of the base device 3 on the first component 100 in the left and right directions. In some embodiments, the problem that the left and right adjustment strip holes of the straight base hinge easily cause the binding force between the fastener, the strip hole and the first component 100 to be insufficient, resulting in the cabinet door moving downward is overcome.

In this embodiment 1, at least a portion of the outer wall or the inner wall of the first adjustment part 33 can be a threaded structure or a toothed structure, such as an external threaded part such as a screw or a bolt or a stud or a screw, or the first adjustment part 33 is a rack structure, which can drive the first main body 1 to achieve translation and lifting only in the up and down directions relative to the first adjustment component 31 through the tooth engagement.

Example 2

This embodiment 2 discloses a hinge assembly for furniture, which is a further design of the hinge assembly of the above embodiment 1. Specifically, as shown in Figures 22 to 24, the first body 1 of this embodiment 2 includes a connecting plate 11, a left side plate 12 and a right side plate 13. The left side plate 12 is connected to the left side of the connecting plate 11 and extends downward, and the right side plate 13 is connected to the right side of the connecting plate 11 and extends downward. The connecting plate 11, the left side plate 12 and the right side plate 13 enclose a mounting groove 14. Along the projection direction perpendicular to the connecting plate 11, the distance between the left and right edges of the base device 3 and the inner projection edge of the mounting groove 14 is less than 3 mm. It is understandable that the left and right sides of the base device 3 can be located in the internal projection of the mounting groove 14, or the left and right edges of the base device 3 can be slightly protruded from the internal projection of the mounting groove 14, for example, the distance between the left and right edges of the base device 3 and the internal projection of the mounting groove 14 is 0.5mm, 1mm, 1.5mm, 2mm, 3mm, etc. When the hinge assembly is observed in the projection direction perpendicular to the connecting plate 11, the left and right edge portions of the base device 3 are exposed in the first body 1 in a very small area or almost no area, and the user can hardly observe the base device 3 from the outside or can only see a very small part of the base device 3, so as to make the appearance more beautiful. At the same time, compared with the existing hinge, the base device 3 of the utility model is smaller in volume and area, saving the overall use of materials, reducing the difficulty of the process, thereby reducing the cost of manufacturing, and the base device 3 with a smaller area can save the use space and provide space utilization.

In some embodiments, along the projection direction perpendicular to the connecting plate 11, the base device 3 is located within the internal projection of the mounting groove 14. Since the area of the base device 3 along the projection direction perpendicular to the connecting plate 11 is smaller than the area of the connecting plate 11, so that the base device 3 is located within the internal projection of the mounting groove 14, it is difficult for the user to observe the base device 3 from the outside or only a very small part of the base device 3 can be seen, so that the aesthetics are higher; and when the user observes the hinge in the direction perpendicular to the connecting plate 11, the base device 3 is in a completely invisible state, so as to give the impression that there is no hinge of the base device 3, making the hinge more beautiful. At the same time, compared with the existing base device 3, the base device 3 of the utility model is smaller in volume and area, saving the overall use of materials, reducing the difficulty of the process, thereby reducing the cost of manufacturing, and the base device 3 with a smaller area can save the use space and provide space utilization.

In some embodiments, when the first body 1 is at the lowest position, the base device 3 is within the internal projection of the installation slot 14 along the projection direction perpendicular to the left plate 12 or the right plate 13. In the process of driving the first body 1 to move only in the up and down directions relative to the first adjustment assembly 31 by adjusting the first adjustment portion 33 alone, when the first body 1 is adjusted to the lowest position, the base device 3 is completely located inside the installation slot 14, and the base device 3 cannot be observed from the left or right direction, so as to give the impression that there is no base hinge, thereby improving the aesthetics of the hinge assembly.

In some embodiments, the lower ends of the left side plate 12 and/or the right side plate 13 form a straight line. The lower ends of the left side plate 12 and/or the right side plate 13 are flush with the lower end of the base device 3, or the base device 3 is completely located inside the mounting groove 14. When the hinge assembly is observed from a direction perpendicular to the left side plate 12 or the right side plate 13, the user cannot observe the base device 3, that is, when observing the lower ends of the left side plate 12 and/or the right side plate 13, they form a straight line, thereby improving the aesthetics of the hinge assembly.

In some embodiments, as shown in FIG. 70 , the base device 3 has at least two through holes 37 for fasteners to pass through; the hinge assembly further includes a first connecting member 81, one end of the first connecting member 81 is hinged to the hinge head 2 through a first hinge shaft 82, and the other end of the first connecting member 81 is hinged to the first main body 1 through a third hinge shaft 83; the hinge head 2 and the first main body 1 are rotatably connected through the first connecting member 81; wherein, the through holes 37 are, for example, two, three or four, and the plane formed by the axes of the two through holes 37 is not perpendicular to the third hinge shaft 83. After passing through the two through holes 37, the two fasteners are fastened to the inner side of the cabinet, and the two fasteners are arranged diagonally, so that the base device 3 is stably fastened to the cabinet, and the user is difficult to observe the base device 3 from the outside or can only see a small part of the base device 3. At the same time, two fasteners can usually be used to fix the base device 3 on the cabinet board, reducing installation trouble and reducing the number of fasteners, improving the installation firmness of the base device 3, and reducing installation costs.

Example 3

The present embodiment 3 discloses a hinge assembly for furniture, which is a further design of the hinge assembly of the above-mentioned embodiment 1. Specifically, as shown in Figures 17 to 19, the first body 1 of the present embodiment 3 includes a connecting plate 11, a left side plate 12, a right side plate 13 and a rear side plate 15, the left side plate 12 is connected to the left side of the connecting plate 11 and extends downward, the right side plate 13 is connected to the right side of the connecting plate 11 and extends downward, the rear side plate 15 is located at the rear side of the connecting plate 11 and/or the left side plate 12 and/or the right side plate 13 and extends downward, and the connecting plate 11, the left side plate 12, the right side plate 13 and the rear side plate 15 are surrounded to form a mounting groove 14; wherein, one or more of the connecting plate 11, the right side plate 13 and the left side plate 12 are fixedly connected to the rear side plate 15; the distance between the bottom of the rear side plate 15 and the bottom of the left side plate 12 is -3mm to 1mm, and/or, the distance between the bottom of the rear side plate 15 and the bottom of the right side plate 13 is -3mm to 1mm. It can be understood that the rear side panel 15 is connected to the rear end of the connecting plate 11, or the rear side panel 15 is connected to the rear end of the right side panel 13, or the rear side panel 15 is connected to the rear end of the left side panel 12, or the rear side panel 15 is connected to the rear ends of the connecting plate 11 and the left side panel 12 at the same time, etc., specifically, the metal parts with an integrated structure are formed by a bending process or a casting process, the overall structural strength is relatively large, and the structural stability is improved. Among them, the distance between the bottom of the rear side panel 15 and the bottom of the left side panel 12 or the right side panel 13 is -3mm, -2mm, 0mm, 1mm, etc. Since the bottom of the rear side panel 15 and the bottom of the left side panel 12 and/or the right side panel 13 are located in the same horizontal plane or close to the same horizontal plane, the rear side of the rear side panel 15, the rear side of the left side panel 12 and the rear side of the right side panel 13 are not exposed. The rear end of the first main body 1 is closed or nearly closed by the rear side panel 15, thereby avoiding or reducing the possibility of damage to clothing after touching the rear end of the first main body 1, or scratching of human skin by the rear end of the first main body 1. At the same time, some components of the hinge assembly are wrapped inside the first main body 1, and the user does not need to see some components of the hinge assembly from the outside, thereby improving the overall aesthetics.

Furthermore, in some embodiments, the distance between the bottom of the rear side panel 15 and the bottom of the left side panel 12 is -2 mm to 1 mm, and/or the distance between the bottom of the rear side panel 15 and the bottom of the right side panel 13 is -2 mm to 1 mm. Further, the bottom of the rear side panel 15 and the left side panel 12 and/or the right side panel 13 are located at the same horizontal plane or close to the same horizontal plane, so that the rear end of the first body 1 is closed or close to closed, effectively avoiding or reducing the possibility of damage to clothing after contact with the rear end of the first body 1, or scratching of human skin by the rear end of the first body 1.

Furthermore, the bottom of the rear side panel 15 is located on the same horizontal plane as the bottom of the left side panel 12, and/or the bottom of the rear side panel 15 is located on the same horizontal plane as the bottom of the right side panel 13. Further, the bottom of the rear side panel 15 is located on the same horizontal plane as the left side panel 12 and/or the right side panel 13, so that the rear end of the first body 1 is closed, effectively avoiding or reducing the possibility of damage to clothing after contact with the rear end of the first body 1, or scratching of human skin by the rear end of the first body 1.

Example 4

The present embodiment 4 discloses a hinge assembly for furniture, which is a further design of the hinge assembly of the above-mentioned embodiment 1. Specifically, as shown in Figures 64 to 65, the hinge assembly of the present embodiment 4 also includes a first connecting member 81 and a second connecting member 84. One end of the first connecting member 81 is hinged to the hinge head 2 through a first hinge shaft 82, and the other end of the first connecting member 81 is hinged to the first main body 1 through a third hinge shaft 83; one end of the second connecting member 84 is hinged to the hinge head 2 through a second hinge shaft 85, and the other end of the second connecting member 84 is hinged to the first main body 1 through a fourth hinge shaft 86, and a part of the second connecting member 84 is located below the first connecting member 81; the hinge head 2 and the first main body 1 are rotatably connected through the first connecting member 81 and the second connecting member 84. The hinge assembly also includes at least two first elastic members 87, which are respectively sleeved on the third hinge shaft 83, and each first elastic member 87 has a first abutting end and a second abutting end. The first abutting end of each first elastic member 87 abuts against the first connecting member 81, and the second abutting end of each first elastic member 87 abuts against the first main body 1 or the fourth hinge shaft 86; wherein, the hinge head 2 rotates relative to the first main body 1 through the first connecting member 81 and the second connecting member 84; when the hinge head 2 rotates a certain angle, the first elastic member 87 drives the hinge head 2 to rotate in the closing direction (the closing direction is the closing direction of the cabinet door relative to the cabinet side panel). Since the number of first elastic members 87 sleeved on the third hinge shaft 83 is at least two, and the first abutting end of each elastic member abuts against the first connecting member 81, and the second abutting end abuts against the first main body 1 or the fourth hinge shaft 86, at least two first elastic members 87 are used to jointly drive the hinge head 2 to automatically reset relative to the first main body 1, thereby increasing the automatic reset force on the hinge head 2, and the reset effect is more stable and reliable. At the same time, at least two first elastic members 87 can effectively improve the fatigue strength of reset and extend the service life of the hinge assembly.

It is understandable that the first elastic member 87 of the present embodiment 4 is, for example, a spring or a torsion spring, and at least two first elastic members 87 are respectively sleeved on the third hinge shaft 83 to jointly drive the hinge head 2 to automatically reset relative to the first body 1.

In some embodiments, the second abutting end of each first elastic member 87 is close to the left inner wall or the right inner wall of the first body 1. By arranging the first abutting ends of the first elastic members 87 at both ends close to the left and right sides of the first body 1, respectively, it is avoided that the second abutting ends of the first elastic members 87 interfere with other parts of the hinge assembly, thereby improving the internal space utilization of the first body 1 and effectively ensuring that the second abutting ends of the first elastic members 87 abut against the first body 1 or the fourth hinge shaft 86.

Further, in some embodiments, as shown in FIG. 65 , the hinge assembly of the present embodiment 4 includes two first elastic members 87, and the first abutting ends of the two first elastic members 87 are connected as one body or the second abutting ends of the two first elastic members 87 are connected as one body, for example, the first abutting ends or the second abutting ends of the first elastic members 87 are formed into an integrated structure by welding or casting. When the number of the first elastic members 87 is two, and the two first elastic members 87 are symmetrically arranged about the axis, the reset force of the two first elastic members 87 driving the hinge head 2 is more uniform, further extending the service life of the hinge assembly. At the same time, the first abutting ends or the second abutting ends of the two first elastic members 87 are connected as one body, so that the two first elastic members 87 are combined into one body, which is conducive to improving the assembly efficiency, and at the same time ensures the stability of the first elastic member 87 driving the hinge head 2 to reset and enhances the driving force driving the hinge head 2 to reset.

In some embodiments, the second abutting end of each first elastic member 87 is located between the second connecting member 84 and the inner side wall of the first body 1, thereby improving the internal space utilization of the first body 1 and effectively ensuring that the second abutting end of the first elastic member 87 abuts against the first body 1 or the fourth hinge shaft 86.

The structure of the hinge assembly of the fourth embodiment is, for example, a one-stage force hinge.

Furthermore, when the first elastic member 87 is a torsion spring, the wire diameter of the first elastic member 87 is greater than or equal to 2.2 mm. When the hinge head 2 rotates to a certain angle relative to the first body 1, the first elastic member 87 is used to drive the hinge head 2 to move in the closing direction, playing an automatic reset role. The first elastic member 87 with a wire diameter greater than or equal to 2.2 mm can provide a stronger and more stable torque, thereby improving the stability of the hinge head 2 rotation, or reducing the torsion angle of the spring reset, extending the service life of the spring, and thus extending the service life of the hinge.

Furthermore, when the first elastic member 87 is a torsion spring, the number of turns of the first elastic member 87 is greater than or equal to 8. The first elastic member 87 with a number of turns greater than or equal to 8 can provide a stronger and more stable torsion, thereby improving the stability of the rotation of the hinge head 2 and extending the service life of the spring and the hinge.

Example 5

The present embodiment 5 discloses a hinge assembly for furniture, which is a further design of the hinge assembly of the above-mentioned embodiment 1. Specifically, as shown in Figures 66 to 67, the hinge assembly of the present embodiment 5 also includes a first connecting member 81 and a second connecting member 84. One end of the first connecting member 81 is hinged to the hinge head 2 through a first hinge shaft 82, and the other end of the first connecting member 81 is hinged to the first main body 1 through a third hinge shaft 83; one end of the second connecting member 84 is hinged to the hinge head 2 through a second hinge shaft 85, and the other end of the second connecting member 84 is hinged to the first main body 1 through a fourth hinge shaft 86, and a part of the second connecting member 84 is located below the first connecting member 81; the hinge head 2 and the first main body 1 are connected through the first connecting member 81 and the second connecting member. The connecting member 84 realizes the rotational connection; the hinge assembly also includes at least two second elastic members 88, at least two second elastic members 88 are respectively mounted on the third hinge shaft 83, each second elastic member 88 has a first abutting end and a second abutting end, the first abutting end of each second elastic member 88 abuts against the first main body 1 or the fourth hinge shaft 86, and the second abutting end of each second elastic member 88 abuts against the first hinge shaft 82; wherein, the hinge head 2 rotates relative to the first main body 1 through the first connecting member 81 and the second connecting member 84; when the hinge head 2 rotates a certain angle, the second elastic member 88 drives the hinge head 2 to rotate in the closing direction. Since the number of second elastic members 88 sleeved on the third hinge shaft 83 is at least two, and the first abutting end of each second elastic member 88 abuts against the first main body 1, and the second abutting end abuts against the first hinge shaft 82, at least two second elastic members 88 are used to jointly drive the hinge head 2 to automatically reset relative to the first main body 1, thereby increasing the automatic reset force on the hinge head 2, and the reset effect is more stable and reliable. At the same time, at least two second elastic members 88 can effectively improve the fatigue strength of reset and extend the service life of the hinge assembly.

It can be understood that the second elastic member 88 of this embodiment 5 is, for example, a spring or a torsion spring, and has the same structure as the first elastic member 87 of the above-mentioned embodiment 4. For example, the wire diameter of the second elastic member 88 is greater than or equal to 2.2 mm; for another example, the number of turns of the second elastic member 88 is greater than or equal to 8 turns.

Furthermore, in some embodiments, the hinge assembly of the present embodiment 5 includes two second elastic members 88, and the second abutting ends of the two second elastic members 88 are respectively located on the left and right sides of the first connecting member 81. The two second elastic members 88 arranged symmetrically on the axis can more stably and evenly drive the hinge head 2 to rotate in the closing direction relative to the first body 1 (the closing direction is the closing direction of the cabinet door relative to the cabinet side body), further extending the service life of the hinge assembly; at the same time, the second abutting ends of the second elastic members 88 are prevented from interfering with other components of the hinge assembly, ensuring the smooth hinge connection between the hinge head 2 and the first connecting member 81.

In some embodiments, the first abutting ends of the two second elastic members 88 are connected as one body, for example, by welding or casting into an integrated structure.

The two ends of the first connection part 841 are respectively hinged to the hinge head 2 and the first main body 1, the two ends of the second connection part 842 are respectively hinged to the hinge head 2 and the first main body 1, and the second end of the first connection part 841 is connected to the telescopic member 92. When the hinge head 2 rotates in the closing direction relative to the first main body 1, the first connection part 841 drives the telescopic member 92 to contract, and the buffer device 9 is used to buffer the movement of the first connection part 841, so that the cabinet door has a buffer effect during the closing process. By dividing the second connection part 84 into the first connection part 841 and the second connection part 842 with different structures, the first connection part 841 controls the position of the telescopic member 92 of the buffer device 9, and the second connection part 842 stabilizes the movement of the hinge head 2, thereby enhancing the overall strength of the second connection part 84, and improving the overall force uniformity of the hinge head 2 during the rotation process, thereby enhancing the overall strength of the hinge assembly, improving the stability of the movement of the hinge head 2, and extending the service life of the hinge assembly.

Among them, the first connecting part 841 of this embodiment 7 can be a laminated structure, and the second connecting part 842 can be a square sheet structure.

The second end of the first connection portion 841 is directly or indirectly connected to the telescopic member 92, so that during the rotation of the first connection portion 841, the telescopic member 92 moves in the front-to-back direction to play a buffering effect. The telescopic member 92 of the buffer device 9 can move in the left-right direction. The telescopic member 92 is, for example, a piston. The second end of the first connection part 841 is transmitted with the telescopic member 92 by gear meshing. Specifically, the second end of the first connection part 841 is provided with a gear, and the telescopic member 92 is also formed with a gear. The transmission is achieved by the mutual meshing of the gears of the two. When the first connection part 841 rotates, the movement of the first connection part 81 in the front-to-back direction is converted into the movement of the telescopic member 92 in the left-to-right direction through the gear transmission, thereby achieving a buffering effect. Among them, the buffer device 9 of this embodiment 7 can also be the structure of other existing buffer devices 9 used for hinges, and the telescopic method of the buffer device 9 is not limited.
