The back cover 300 may be provided with a mating hole 301, so that the camera mechanism 100 can extend from the mating hole 301.

Please refer to Figures 3 to 8, Figure 3 is a perspective schematic diagram of the first state of the camera mechanism in the electronic device shown in Figure 2, Figure 4 is a cross-sectional schematic diagram of the electronic device shown in Figure 3 along the B-B direction, Figure 5 is a perspective schematic diagram of the partial structure of the camera mechanism shown in Figure 3, Figure 6 is a partial enlarged view of area C shown in Figure 4, Figure 7 is a cross-sectional schematic diagram of the second state of the camera mechanism in the electronic device shown in Figure 3, and Figure 8 is a partial enlarged view of area D shown in Figure 7. The camera mechanism 100 may include a sealing component 10, a lens group 20, a module substrate 30, an image sensor 40, and a driving component 50.

Specifically, the sealing assembly 10 may include a shell 11, a movable part 12, a sealing part 13 and a waterproof breathable part 14. The shell 11 may have a receiving cavity 110 and a through hole 101 connected to the receiving cavity 110. One end of the movable part 12 is received in the receiving cavity 110, and the other end is passed through the through hole 101 and can perform telescopic movement along the through hole 101. The sealing part 13 is fixed to the shell 11 and surrounded by the edge of the through hole 101. The sealing part 13 is sleeved on the movable part 12 and elastically abuts against the movable part 12, forming a first line of protection for the gap between the shell 11 and the movable part 12. The waterproof breathable part 14 is sleeved on the movable part 12. One end of the waterproof breathable part 14 is connected to the movable part 12, and the other end is connected to the shell 11, forming a second line of protection between the shell 11 and the movable part 12.

The first line of protection formed by the sealing member 13 can not only be used to block dust particles, dust, a small amount of splashing water and immersion, but also protect the waterproof breathable member 14 from dust pollution, ensuring the air permeability of the waterproof breathable member 14. The second line of protection formed by the waterproof breathable member 14 can ensure the waterproof performance of the sealing structure when the water flow speed is too large or the water pressure of the immersion increases.

Furthermore, one end of the movable part 12 can be received in the through hole 101, and the waterproof breathable part 14 is in an extended state; the end of the movable part 12 received in the through hole 101 can extend from the through hole 101, thereby driving the waterproof breathable part 14 fixed on the movable part 12 to move, and making the waterproof breathable part 14 in a folded state. That is, the waterproof breathable part 14 can move with the movement of the movable part 12 and adjust its own state, on the one hand, meeting the activity requirements of the movable part 12 relative to the shell 11, and on the other hand ensuring the reliability of the sealing between the movable part 12 and the shell 11, and balancing the pressure difference between the inside and outside of the accommodating cavity 110.

The lens group 20 is fixed on the movable part 12 and can move with the movable part 12. The module substrate 30 is received in the accommodating cavity 110 and is spaced apart from the movable part 12. The image sensor 40 is attached to a surface of the module substrate 30 facing the movable part 12 and is arranged corresponding to the lens group 20. One end of the driving assembly 50 can be fixed on the module substrate 30, and the other end can be connected to the movable part 12.

Specifically, the driving component 50 can drive the movable part 12 to extend from the through hole 101, so that the lens group 20 moves to a preset imaging position, thereby completing the focusing during the imaging process, or the driving component 50 can drive the movable part 12 to be accommodated in the accommodating cavity 110, which can protect the lens group 20 on the one hand, and make the electronic device 1000 look neat and beautiful on the other hand.

It should be noted that the terms "first", "second", and "third" in this application are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first", "second", and "third" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

Please refer to FIG. 2 and FIG. 6 . Specifically, the housing 11 may include a bottom plate 111 and a side edge 112 extending from the edge of the bottom plate 111. The accommodating cavity 110 may be surrounded by the bottom plate 111, the side edge 112 and the display assembly 200. The bottom plate 111 may include a first surface 1111 and a second surface 1112 disposed opposite to each other, wherein the first surface 1111 is disposed away from the accommodating cavity 110, and the second surface 1112 is located in the accommodating cavity 110. The through hole 101 may be disposed on the bottom plate 111 or on the side edge 112, and no specific limitation is made here. In this embodiment, the through hole 101 is disposed on the bottom plate 111.

The first surface 1111 of the housing 11 abuts against the inner surface of the rear cover 300 , and the through hole 101 is arranged corresponding to the matching hole 301 , so that the movable member 12 can pass through the through hole 101 and the matching hole 301 in sequence.

The movable part 12 is mainly used to drive the lens group 20 to move to a preset imaging position. At the same time, the movable part 12 is also integrated with an optical image stabilization module and an autofocus module, which is used to enable the lens group 20 to move accurately at the order of hundreds of microns, thereby ensuring accurate focus and clear imaging during the imaging process. Specifically, the movable part 12 may include a main body 121, and the main body 121 includes a first end 1211 and a second end 1212 that are arranged opposite to each other, wherein the first end 1211 is received in the accommodating cavity 110, and the second end 1212 is received in the through hole 101 and can reciprocate in the through hole 101.

Optionally, the movable member 12 may further include a limiting portion 122, which is disposed on the side of the first end 1211 of the movable member 12. The limiting portion 122 can abut against the second surface 1112 of the housing 11 (i.e., the inner surface of the housing 11). On the one hand, it can be used to limit the movement range of the movable member 12 to prevent the movable member 12 from being separated from the through hole 101, and on the other hand, it can be used to connect and fix the waterproof breathable member 14. Specifically, when the first end 1211 is accommodated in the through hole 101, that is, the end surface of the first end 1211 is flush with the first surface 1111 or slightly lower than the first surface 1111, the limiting portion 122 is spaced apart from the second surface 1112 of the housing 11; when the second end 1212 extends from the through hole 101 and reaches the preset position, the limiting portion 122 abuts against the second surface 1112 of the housing 11.

8, further, the limiting portion 122 is annular in structure, and the limiting portion 122 is fixedly mounted on the main body 121. In one embodiment, the waterproof breathable member 14 is mounted on the movable member 12 and one end is bonded and fixed to the limiting portion 122 to achieve the connection between the movable member 12 and the waterproof breathable member 14.

Please refer to FIG. 6, FIG. 8, FIG. 9 and FIG. 10 together. FIG. 9 is a three-dimensional schematic diagram of the seal of the sealing assembly in the camera mechanism shown in FIG. 8, and FIG. 10 is a cross-sectional schematic diagram of the seal shown in FIG. 9 along the E-E direction. The seal 13 may include an annular fixed portion 131 and a contact portion 132 extending from the inner edge of the fixed portion 131. The fixed portion 131 is connected to the housing 11, and the edge of the contact portion 132 away from the fixed portion 131 elastically abuts against the side of the movable member 12. That is, the fixed portion 131 is fixed to the housing 11 to achieve a sealed connection between the fixed portion 131 and the housing 11; the contact portion 132 elastically abuts against the movable member 12, so that the contact portion 132 and the movable member 12 are interference-fitted, and then the contact portion 132 and the movable member 12 are sealed. In other words, the setting of the seal 13 can make the movable member 12 and the housing 11 sealed. Specifically, the material of the seal 13 can be elastic material such as rubber, silicone, etc., so that the seal 13 can be deformed when in contact with the movable part 12, which not only ensures that the movable part 12 slides relative to the seal 13, but also improves the sealing performance between the movable part 12 and the seal 13.

In this embodiment, the fixing portion 131 includes a first fixing plate 1311, and the contact portion 132 is formed by extending from the inner edge of the first fixing plate 1311, and the contact portion 132 is arranged at an obtuse angle with the first fixing plate 1311. In this arrangement, when the movable member 12 extends from the through hole 101, even if the contact portion 132 and the movable member 12 have an interference fit, the positive pressure applied by the contact portion 132 to the movable member 12 is small, so that the movable member 12 is easy to move relative to the housing 11 and the contact portion 132.

Optionally, the first fixing plate 1311 may be attached to the first surface 1111 (please refer to FIG. 6 ) or to the second surface 1112 (not shown). When the first fixing plate 1311 is attached to the first surface 1111, that is, the sealing member 13 is disposed outside the accommodating cavity 110, the end of the contact portion 132 away from the first fixing plate 1311 may be received in the through hole 101, or may be disposed away from the through hole 101, and no specific limitation is made here. When the first fixing plate 1311 is attached to the second surface 1112, that is, the sealing member 13 is accommodated in the accommodating cavity 110, the end of the contact portion 132 away from the first fixing plate 1311 may be received in the through hole 101, or may be disposed away from the through hole 101, and no specific limitation is made here.

Please refer to FIG. 6 or FIG. 8 , in this embodiment, the contact portion 132 may include a first contact plate 1321, which is formed by extending from the inner edge of the first fixed plate 1311, and the edge of the first contact plate 1321 away from the first fixed plate 1311 is elastically abutted against the side of the movable member 12, so that the movable member 12 can slide relative to the first contact plate 1321 on the one hand, and the movable member 12 and the first contact plate 1321 can be interference-fitted on the other hand, thereby improving the sealing performance of the movable member 12 and the first contact plate 1321. Specifically, the cross-section of the first contact plate 1321 may be substantially funnel-shaped, and the diameter of the first contact plate 1321 gradually decreases from the end connected to the first fixed plate 1311 to the end away from the first fixed plate 1311.

Referring to FIG. 10 , in another embodiment, the contact portion 132 may include a first contact plate 1321 and a second contact plate 1322, and the first contact plate 1321 and the second contact plate 1322 are respectively extended from the inner edge of the first fixed plate 1311. Specifically, one end of the first contact plate 1321 is connected to the first fixed plate 1311 of the fixed portion 131, and the other end is elastically abutted against the side surface of the movable member 12; one end of the second contact plate 1322 is connected to the first fixed plate 1311 of the fixed portion 131, and the other end is elastically abutted against the side surface of the movable member 12. The first contact plate 1321 elastically abuts against the movable member 12 to achieve the first layer of sealing of the sealing member 13; the second contact plate 1322 elastically abuts against the movable member 12 to achieve the second layer of sealing of the sealing member 13, that is, the arrangement of the first contact plate 1321 and the second contact plate 1322 can achieve double-layer sealing of the sealing member 13.

Further, the first contact plate 1321 and the second contact plate 1322 are arranged at an angle. Specifically, the cross section of the first contact plate 1321 may be roughly funnel-shaped, and the diameter of the first contact plate 1321 gradually decreases from the end connected to the first fixed plate 1311 to the end away from the first fixed plate 1311. The cross section of the second contact plate 1322 may be roughly funnel-shaped, and the diameter of the first contact plate 1321 gradually decreases from the end connected to the first fixed plate 1311 to the end away from the first fixed plate 1311. Among them, the first contact plate 1321 and the second contact plate 1322 may be located on opposite sides of the first fixed plate 1311, that is, the angle formed by the first contact plate 1321 and the second contact plate 1322 is an obtuse angle. Alternatively, the first contact plate 1321 and the second contact plate 1322 are located on the same side of the first fixed plate 1311, that is, the angle formed by the first contact plate 1321 and the second contact plate 1322 is an acute angle.

Of course, the first contact plate 1321 and the second contact plate 1322 may also be stacked or arranged in parallel and spaced apart, which is not specifically limited here.

Please refer to FIG. 11 , which is a cross-sectional schematic diagram of a deformation of the sealing member shown in FIG. 10 . In another embodiment, the fixing portion 131 may include a first fixing plate 1311, a second fixing plate 1312, and a connecting plate 1313 connecting the first fixing plate 1311 and the second fixing plate 1312, the connecting plate 1313 and the first fixing plate 1311 and the second fixing plate 1312 enclose a fixing groove 1310, the fixing groove 1310 is clamped and fixed to the housing 11, and the fixing groove 1310 accommodates the edge of the housing 11 corresponding to the through hole 101. In other words, the first fixing plate 1311 and the second fixing plate 1312 are respectively disposed on the two side surfaces (i.e., the first surface 1111 and the second surface 1112) of the housing 11 that are disposed opposite to each other, and the connecting plate 1313 is attached to the inner wall of the through hole 101, so that the fixing portion 131 is clamped and connected to the housing 11 and is surrounded by the through hole 101.

In this embodiment, the contact portion 132 may include a first contact plate 1321, which is formed by extending from the inner edge of the first fixed plate 1311, and the edge of the first contact plate 1321 away from the first fixed plate 1311 elastically abuts against the side of the movable member 12. Alternatively, the first contact plate 1321 is formed by extending from the inner edge of the second fixed plate 1312, and the edge of the first contact plate 1321 away from the second fixed plate 1312 elastically abuts against the side of the movable member 12. Alternatively, the first contact plate 1321 is formed from the inner surface of the connecting plate 1313, and the edge of the first contact plate 1321 away from the first fixed plate 1311 elastically abuts against the side of the movable member 12. With such a configuration, on the one hand, the movable member 12 can slide relative to the first contact plate 1321, and on the other hand, the movable member 12 can be interference-fitted with the first contact plate 1321, thereby improving the sealing performance between the movable member 12 and the first contact plate 1321.

Specifically, the cross section of the first contact plate 1321 may be substantially funnel-shaped, and the diameter of the first contact plate 1321 gradually decreases from an end connected to the first fixing plate 1311 to an end away from the first fixing plate 1311 .

Please refer to FIG. 12, which is a cross-sectional schematic diagram of another deformation of the sealing member shown in FIG. 10. In another embodiment, the contact portion 132 may include a first contact plate 1321 and a second contact plate 1322, wherein the first contact plate 1321 is formed by extending from the inner edge of the first fixed plate 1311, and the second contact plate 1322 is formed by extending from the inner edge of the second fixed plate 1312. Specifically, one end of the first contact plate 1321 is connected to the first fixed plate 1311 of the fixed portion 131, and the other end is elastically abutted against the side surface of the movable member 12; one end of the second contact plate 1322 is connected to the second fixed plate 1312 of the fixed portion 131, and the other end is elastically abutted against the side surface of the movable member 12. Among them, the first contact plate 1321 elastically abuts against the movable part 12 to achieve the first layer of sealing of the seal 13; the second contact plate 1322 elastically abuts against the movable part 12 to achieve the second layer of sealing of the seal 13, that is, the setting of the first contact plate 1321 and the second contact plate 1322 can achieve double-layer sealing of the seal 13.

Further, the first contact plate 1321 and the second contact plate 1322 are arranged at an angle. Specifically, the cross section of the first contact plate 1321 may be roughly funnel-shaped, and the diameter of the first contact plate 1321 gradually decreases from the end connected to the first fixed plate 1311 to the end away from the first fixed plate 1311. The cross section of the second contact plate 1322 may be roughly funnel-shaped, and the diameter of the first contact plate 1321 gradually decreases from the end connected to the first fixed plate 1311 to the end away from the first fixed plate 1311. Among them, the first contact plate 1321 and the second contact plate 1322 may be located on opposite sides of the first fixed plate 1311, that is, the angle formed by the first contact plate 1321 and the second contact plate 1322 is an obtuse angle. Alternatively, the first contact plate 1321 and the second contact plate 1322 are located on the same side of the first fixed plate 1311, that is, the angle formed by the first contact plate 1321 and the second contact plate 1322 is an acute angle.

Please refer to Figure 13, which is a cross-sectional schematic diagram of another deformation of the seal shown in Figure 10. In another embodiment, the contact portion 132 is formed by protruding from the inner surface of the connecting plate 1313. Specifically, the contact portion 132 can be annular and the cross-sectional shape of the contact portion 132 can be semicircular, so that the contact portion 132 is in point-to-surface contact with the side surface of the movable member 12, reducing the friction between the contact portion 132 and the movable member 12.

Please continue to refer to Figures 6 and 8. The waterproof breathable member 14 is sleeved on the movable member 12, and one end of the waterproof breathable member 14 is fixedly connected to one end of the movable member 12, and the other end is fixedly connected to the shell 11 and communicated with the through hole 101. The second end 1212 of the movable member 12 can reciprocate in the through hole 101, and can drive the waterproof breathable member 14 to move with the movable member 12, so that the waterproof breathable member 14 can be in a folded or extended state. Specifically, when the second end 1212 is accommodated in the through hole 101, the waterproof breathable member 14 is in an extended state, and when the second end 1212 extends from the through hole 101, the waterproof breathable member 14 is in a folded state. It can be understood that no matter whether the waterproof breathable member 14 is in an extended state or a folded state, the waterproof breathable member 14 can always block the internal and external communication of the accommodating cavity 110.

Furthermore, the waterproof breathable member 14 is a waterproof breathable membrane, and the waterproof function of the waterproof breathable member 14 can ensure the waterproof performance of the accommodating chamber 110 under splashing or high water pressure conditions, and the breathability of the waterproof breathable member 14 can achieve gas exchange inside and outside the accommodating chamber 110, avoiding excessive pressure difference inside and outside the accommodating chamber 110, and preventing the movable member 12 from popping out normally. In addition, the provision of the waterproof breathable membrane can eliminate other breathable holes in the accommodating chamber 110, which can reduce the processing difficulty of the housing 11 and further improve the sealing performance of the sealed chamber.

Optionally, one end of the waterproof breathable member 14 is fixed to the limiting portion 122, specifically, it can be bonded and fixed to the limiting portion 122 by double-sided tape or glue, and the other end can be located between the fixing plate and the shell 11, thereby achieving a fixed connection between the waterproof breathable member 14 and the shell 11.

Specifically, when the fixing portion 131 is located on the first surface 1111 of the housing 11, the end of the waterproof breathable member 14 away from the limiting portion 122 can pass through the through hole 101 and be located between the fixing portion 131 and the first surface 1111. When the fixing portion 131 is located on the second surface 1112 of the housing 11, the waterproof breathable member 14 can be directly located between the fixing portion 131 and the second surface 1112.
