Description

Clamshell electronic device structure

technical field

The invention relates to a structural design of an electronic device, in particular to a clamshell electronic device structure with upper and lower bodies pivotally connected to each other.

Background technique

With the rapid development of science and technology, the development of the electronics industry is even more rapid. Modern people often use electronic devices. In order to make these electronic devices not easy to be damaged, and considering factors such as thin and light volume, these electronic devices will be designed as clamshell structures, such as consumer electronics such as notebook computers and personal digital assistants. product.

A conventional clamshell electronic device includes two bodies that are pivotally connected to each other. When the two bodies are close to each other, components on the body can be protected, and when the two bodies are unfolded correspondingly, they can be used by the user.

Taking a notebook computer as an example, it has a touch-sensitive display screen and a main body, and the display screen and the main body are pivotally connected to each other by using a rotating shaft structure to serve as a rotation axis between the display screen and the main body, so that the display screen and the main body The bodies are connected and rotated with each other through the rotating shaft structure. The structure of the rotating shaft connected to the display screen of the electronic device and the main body of the host can be roughly divided into two types: a single-axis rotating shaft structure and a bi-axial rotating shaft structure.

The uniaxial shaft structure can only make the display screen cover the upper side of the main body (that is, the closed state), or make the display screen open and tilt at a certain angle relative to the main body (that is, the use state). The uniaxial hinge structure cannot make the display screen rotate axially relative to the host body, that is to say, the uniaxial hinge structure cannot turn the display screen 180° and combine it with the host body in a face-up direction, thus causing electronic The function of the device in use is quite limited, and the display screen cannot be rotated to use and watch at various angles according to the actual needs of the user. Therefore, the display screen usually has a problem of too small viewing angle. When viewing, good visual effects and display quality cannot be obtained.

The electronic device with biaxial shaft structure can not only make the front of the display screen cover the upper side of the main body, but also make the display screen open and tilt at a certain angle relative to the main body, and can also turn the display screen 180° And cover the host body with the front facing up.

Regardless of whether it is an electronic device with a single-axis shaft structure or a dual-axis shaft structure, there is no positioning mechanism between the display screen and the host body, so there is no stop and hold relationship between the display screen and the host body. The screen only maintains its inclination angle or flip angle depending on the friction between the hinge structure and the host body or the display screen.

When the user uses the electronic device while driving in a bumpy way, or in the process of manipulating the touch screen with fingers, if the force applied to the electronic device is greater than the frictional force between the rotating shaft structure and the electronic device, the display screen That is, it shakes due to the influence of external force, and the display screen may even be displaced (that is, the inclination angle or flip angle of the display screen relative to the host body changes), which will cause considerable inconvenience to the user when viewing or manipulating the electronic device. Discomfort and inconvenience.

Contents of the invention

In view of the above problems, the present invention provides a clamshell electronic device structure, which improves the design of conventional clamshell electronic devices without a positioning mechanism between the display screen and the host body, resulting in unnecessary friction during use of the display screen. Problems with shaking or displacement.

The clamshell electronic device structure disclosed in the present invention includes a first body, a second body, at least one rotating shaft, and at least one fixing component. Wherein, the rotating shaft is connected between the first body and the second body so that the second body can pivot relative to the first body, and the rotating shaft has at least one limiting slot. The fixing component has a pressing piece and at least one limiting piece, wherein the limiting piece protrudes from one end of the pressing piece. The pressing part can move back and forth between the releasing position and the restricting position relative to the rotating shaft, and the limiting part can move back along with the pressing part.

When the pressing part is in the release position, the limiting part remains in the free position; when the pressing part is in the restricting position, the limiting part moves to the clamping position along with the pressing part, and the limiting part is embedded in the limiting groove, so as to The pivoting motion of the second body relative to the first body is restricted.

The effect of the present invention is that after the user pivots the second body to the use angle, the action of the fixing component is used to restrict the second body from being able to continue pivoting relative to the first body, so that the second body is continuously maintained at The most appropriate use angle avoids shaking or even displacement of the second body during use, greatly improving the comfort and convenience of use.

The following specific implementation manners will be described with a notebook computer as the best embodiment of the present invention.

FIG. 1 and FIG. 4 are perspective schematic diagrams and cross-sectional schematic diagrams of the present invention. The clamshell electronic device 100 of the present invention includes a first body 110 , a second body 120 , two opposite rotating shafts 130 , and a fixing component 140 . In this embodiment, the first body 110 is a main body, and the second body 120 is a cover with a display screen, but not limited thereto. In addition, the fixing assembly 140 in this embodiment is arranged correspondingly to one of the rotating shafts 130 , and a group of fixing assemblies 140 can also be arranged correspondingly at the relative positions of the two rotating shafts 130 , which is not limited to this embodiment.

The rotating shaft 130 is arranged on the second body 120, and the rotating shaft 130 is respectively connected to the first body 110 and the second body 120, so that the second body 120 can pivot relative to the first body 110 with the rotating shaft 130 as the pivot axis . In addition, a plurality of limiting grooves 131 are defined on an end surface of the rotating shaft 130 facing the first body 110 , and each of the limiting grooves 131 has a guiding slope 1311 .

Referring to FIGS. 1 to 4 , the fixing assembly 140 of the present invention includes a pressing member 141 , two symmetrically positioned limiting members 142 , a hollow sleeve 143 , a coupling member 144 , and an elastic member 145 . Wherein, the pressing member 141 is a long cylindrical structure, and the outer peripheral surface of the pressing member 141 is concavely provided with a guiding track 1411 , and the guiding track 1411 has a first positioning end 1412 and a second positioning end 1413 . The two limiting pieces 142 are long rectangular plate structures, and protrude from the end surface of the pressing piece 141 along the axial direction of the pressing piece 141 . The limiting part 142 and the pressing part 141 can be integrally formed, or the limiting part 142 and the pressing part 141 are two independent components, which are combined with each other through any combination means, and the present invention is not limited thereto.

The hollow sleeve 143 is disposed on the top surface of the first body 110 , and an accommodating hole extends through the hollow sleeve 143 along the axial direction, so that the interior of the hollow sleeve 143 has an accommodating space communicating with the outside. The shape of the accommodating hole of the hollow sleeve 143 matches the shape of the rotating shaft 130 and the pressing member 141 , so the rotating shaft 130 can just fit inside from one end surface of the hollow sleeve 143 , and the rotating shaft 130 can rotate relative to the hollow sleeve 143 , so as to drive the second body 120 to pivot relative to the first body 110 . The pressing member 141 is sleeved in from the other end surface of the hollow sleeve 143 , and a part of the pressing member 141 is exposed outside, so as to facilitate pressing by the user. The pressing member 141 can move back and forth in the hollow sleeve 143 relative to the rotating shaft 130 between a releasing position and a restricting position, and the pressing member 141 is disposed in the hollow sleeve 143 so that the limiting member 142 faces the rotating shaft 130 . In addition, the inner peripheral surface of the hollow sleeve 143 is further provided with a coupling hole 1431 corresponding to the guiding track 1411 .

The outer peripheral surface of the pressing member 141 in this embodiment is also cut with a first restricting surface 1414, the hollow sleeve 143 also has a second restricting surface 1432, and the pressing member 141 is attached to the second restricting surface 1432 with the first restricting surface 1414. installed in the hollow sleeve 143 in such a way that the pressing piece 141 is limited by the interference of the two limiting surfaces 1414, 1432, so the pressing piece 141 can only move in a linear displacement in the hollow sleeve 143, and cannot move in the hollow sleeve 143. The cylinder 143 rotates relatively.

Please continue to refer to FIG. 1 to FIG. 4 , the coupling part 144 of the fixing component 140 is a long rod structure, and the two ends of which are protrudingly provided with clasps 1441, which are respectively hooked into the coupling hole 1431 of the hollow sleeve 143 and the hole of the pressing part 141. The guiding track 1411 keeps the pressing piece 141 in the hollow sleeve 143 and does not fall off. The elastic member 145 is respectively connected to the pressing member 141 and the rotating shaft 130 , that is, the elastic member 145 is sandwiched between the pressing member 141 and the rotating shaft 130 and provides an elastic force to the pressing member 141 .

The elastic member 145 disclosed in the present invention includes but is not limited to springs, washers, springs and other elastic and compressible components, and the elastic member 145 in this embodiment is a spring, but not limited thereto.

FIG. 5 and FIG. 6 are schematic diagrams of the operating state of the fixing assembly of the present invention.

As shown in Figure 5, when the pressing member 141 is displaced to the release position, the coupling member 144 is hooked to the first positioning end 1412 of the guide track 1411, and the limiting member 142 is held by the elastic push of the elastic member 145. In the free position, there is a predetermined distance between the limiting member 142 and the rotating shaft 130 . Since the limiting member 142 and the rotating shaft 130 do not interfere with each other, the second body 120 can smoothly pivot relative to the first body 110 and be opened to the most appropriate viewing angle or use angle.

As shown in FIG. 6 , when an external force is applied to the pressing member 141 to displace the pressing member 141 to a limited position relative to the rotating shaft 130, the elastic member 145 is compressed by force, and the coupling member 144 slides along the guide track 1411 and is hooked. to the second positioning end 1413 of the guide rail 1411 , and the limiting member 142 is displaced along with the pressing member 141 and remains at the locking position. At this time, the limiting member 142 is embedded in the limiting groove 131 of the rotating shaft 130 , so that a mutually interfering connection relationship is formed between the limiting member 142 and the rotating shaft 130 , so that the second body 120 cannot pivot relative to the first body 110 . The rotating action causes the second body 120 to be firmly maintained at a pivot angle corresponding to the embedded limiting slot 131 . Even if there is a slight deviation in the relative position between the limiting member 142 and the limiting groove 131, the limiting member 142 can smoothly enter the limiting groove 131 along the guiding slope 1311 of the limiting groove 131, At the same time, the second body 120 is passively rotated to a pivot angle corresponding to the limiting slot 131 .

It is worth noting that the multiple limiting grooves 131 of the rotating shaft 130 disclosed in this embodiment are arranged radially at equal intervals on the end surface of the rotating shaft 130, but the number of limiting grooves 131 is not limited, and the limiting member The number of 142 is not limited to the number disclosed in this embodiment. However, as the number of limiting grooves 131 is increased, the fixed position or pivoting angle of the second body 120 is relatively increased, which makes it easier for different users to choose and adjust the second body 120 to the viewing use they think is most suitable. Angle, and firmly keep the second body 120 at this viewing angle without shaking.

To sum up, the clamshell electronic device structure of the present invention can quickly and easily limit the pivoting movement of the second body through the fixing component. After the user pivots the second body to the most appropriate use angle, the user drives the pressing part to displace so that the fixing part and the rotating shaft engage and interfere with each other, restricting the second body from continuing to pivot relative to the first body, so that the second body cannot continue to pivot relative to the first body. The second body continues to maintain this use angle, which effectively prevents the second body from shaking or shifting during viewing and use, and improves the comfort and convenience of use.
