Description

Technical Field

[0001] The present application relates to the field of terminal technology, and in particular to an electronic device. Background Art

[0002] As flexible screen technology matures, the display mode of electronic devices has undergone tremendous changes. One of these is the emergence of foldable mobile phones, computers and other electronic devices. The flexible screens of foldable electronic devices can flexibly change modes according to different usage scenarios. At the same time, they also have a high screen-to-body ratio and clarity. For example, when the phone is folded, it can be only the size of a traditional phone, which is convenient to carry, and when unfolded, it can have the display size of a tablet. These features make foldable devices one of the products that people are most sought after.

[0003] Currently, foldable electronic devices typically include a first shell and a second shell that can rotate relative to each other. The first shell and the second shell can move toward each other to a folded state, or the first shell and the second shell can move away from each other to an unfolded state. To enable the first shell and the second shell to remain in the folded state for a long time, the first shell is usually provided with a retractable clip. One end of the clip is located within the first shell, and the other end can be retracted into the first shell or extended out of the first shell. The second shell is provided with a snap-fit position. When the first shell and the second shell are in the folded state, the other end of the clip extends out of the first shell and into the snap-fit position, thereby locking the first shell and the second shell, and keeping the electronic device in the folded state. A button is also provided on the first shell, and a driving member and a rolling member can also be provided in the first shell. The driving member is usually a cam structure, the cam structure abuts against the rolling member, and the abutting surface is an inclined surface. The cam structure is located below the button, and the rolling member is rollingly connected to one end of the snap-fit member. When the button is pressed, the button squeezes the cam structure to move vertically, thereby driving the rolling member to roll and move laterally. The rolling member drives the snap-fit member to move and causes the other end of the snap-fit member to retract into the first shell, and the snap-fit member is separated from the snap-fit position, thereby expanding the first shell and the second shell.

[0004] However, when pressing the button to retract the clip and unfold the electronic device, the cam structure driving method has a relatively small transmission ratio and a small adjustable range, and the required pressing stroke is relatively large, which affects the pressing experience during use. Summary of the Invention

[0005] The present application provides an electronic device that solves the problem in existing electronic devices that the transmission ratio of the driving structure between the button and the clip-on component is relatively small and the adjustable range is small, resulting in a large button pressing stroke and affecting the pressing experience.

[0006] The present application provides an electronic device, comprising: a first housing and a second housing, wherein the first housing and the second housing are rotatably connected so that the first housing and the second housing can be folded or unfolded relative to each other;

[0007] The first housing is provided with a retractable snap-in member, and the second housing is provided with a snap-in position for cooperating with the snap-in member, and when the electronic device is in a folded state, the snap-in member is located in the snap-in position;

[0008] A button is provided on the first shell, and at least one transmission torsion spring is also provided in the first shell. The transmission torsion spring includes a rotating end and an input end and an output end respectively located on both sides of the rotating end. The transmission torsion spring is rotatably arranged in the first shell through the rotating end. The input end is slidably connected to the button, and the output end is connected to the clamping part. The button is used to push the input end to move, and the output end drives the clamping part to retract toward the inside of the first shell to disengage the clamping part from the clamping position.

[0009] That is, when the button is pressed, it moves in the +z direction, pushing the input end to rotate about the rotating end. The rotation trajectory of the input end includes partial displacements in the +z and +x directions. The rotation of the input end causes the output end to also rotate about the rotating end. The rotation trajectory of the output end is opposite to that of the input end, including partial displacements in the -z and -x directions. The output end can then drive the first end of the engaging member to move in the -x direction, causing the engaging member to retract toward the inside of the first housing. The second end of the engaging member disengages from the engaging position, thereby allowing the first and second housings to expand relative to each other.

[0010] The transmission torsion spring is set to rotate through the rotating end, and the input end and output end on both sides of the rotating end are respectively connected to the button and the card connector. The transmission torsion spring forms a lever structure, which can convert the small stroke of the input end into a large stroke output, that is, the pressing stroke of the button is small, so that when the input end of the transmission torsion spring moves a small stroke, the output end of the transmission torsion spring can also move a large stroke, that is, the stroke that drives the card connector to shrink is large, so that the card connector can achieve a large stroke movement and disengage from the card connector. It has a large transmission ratio, can effectively reduce the pressing stroke of the button, and improve the pressing experience.

[0011] Furthermore, a small stroke at the input is converted into a large stroke at the output, allowing the connector to achieve a large retractive stroke, with a wide adjustable range. The transmission ratio can be adjusted by adjusting the shape of the transmission torsion spring, resulting in high stroke controllability. Furthermore, the transmission torsion spring has a small and simple structure, requiring less space and facilitating installation. This contributes to the lightweight design of electronic devices, making it easy to implement and reducing costs.

[0012] In a possible implementation, the invention further includes an elastic torsion spring, wherein the elastic torsion spring is located in the first shell;

[0013] The elastic torsion spring includes a fixed end and an extended end connected to each other. The elastic torsion spring is arranged in the first shell through the fixed end. The extended end is slidably connected to the button. The button is used to push the extended end to move and compress the elastic torsion spring.

[0014] When the button is pressed, it rotates the transmission torsion spring, which in turn rotates the extended end of the elastic torsion spring. Because the fixed end is fixed to the fixed shaft, this compresses the elastic torsion spring, placing it in a compressed state. When the engaging member is separated from the engaging portion, the button is released, and the rebound force of the compressed elastic torsion spring pushes the button in the opposite direction, returning it to its original position. Simultaneously, the button drives the engaging member via the transmission torsion spring, causing the second end of the engaging member to extend outside the first housing.

[0015] The button is connected to the extended end of the spring, meaning the spring is located on the pressing side. Pressing the button directly acts on the spring, creating a more noticeable feedback force and improving the tactile feel of the button. Furthermore, the dual spring structure, with both the spring and the transmission spring located on the button side, helps to create a more compact structure, further reducing the overall footprint and facilitating installation.

[0016] In a possible implementation, the first end of the clip is located in the first shell, and the second end of the clip extends from or retracts from the first side surface of the first shell.

[0017] The button is located on the second side surface of the first shell, and the first side surface is adjacent to the second side surface.

[0018] In a possible implementation manner, the input end and the extension end are both located on a side of the button close to the second end of the clamping member.

[0019] In a possible implementation manner, the input end is located on a side of the button close to the second end of the clamping member, and the extension end is located on a side of the button away from the second end of the clamping member.

[0020] This can further improve the symmetry of the rebound force applied to the button, further reducing or avoiding the problem of the keycap tilting sideways.

[0021] In a possible implementation manner, a fixed shaft is further provided in the first shell, the rotating end is sleeved on the fixed shaft, and the rotating end is rotatably provided relative to the fixed shaft.

[0022] In a possible implementation manner, the fixed end is sleeved on the fixed shaft.

[0023] In a possible implementation manner, in the extension direction of the fixed shaft, the elastic torsion spring is provided on both sides of the transmission torsion spring.

[0024] This can balance the rebound force applied to the button, reduce or avoid the lateral flipping of the button keycap, extend the service life and improve the user experience.

[0025] In a possible implementation, the button includes a key cap and a slide member;

[0026] The slide member is arranged on a side of the keycap facing the clamping member, and a gap is provided between at least part of the slide member and the keycap to form a slide groove, and the input end and the extension end are both slidably arranged in the slide groove.

[0027] In a possible implementation, the slide member includes a connecting portion and a slide portion;

[0028] The vertical height of the side of the slide portion facing the keycap is lower than the vertical height of the side of the connecting portion facing the keycap. The connecting portion is abutted against the keycap, and the gap between the slide portion and the keycap forms the slide groove.

[0029] In a possible embodiment, a clearance opening is provided on the sliding groove portion, and the clearance opening is used to allow the input end and the extension end to pass through and be disposed in the sliding groove.

[0030] In a possible implementation manner, an adhesive layer is further included, wherein the adhesive layer is located between the connecting portion and the keycap, and the connecting portion is connected to the keycap through the adhesive layer.

[0031] In a possible implementation manner, a mounting groove is formed on the first end of the clamping member, and the output end of the transmission torsion spring is disposed in the mounting groove.

[0032] In a possible embodiment, a receiving groove is provided in the first shell, the notch of the receiving groove is located on the second side surface, and the transmission torsion spring, the elastic torsion spring, and the first end of the clamping member are all located in the receiving groove;

[0033] It also includes a button bracket, which is arranged on the circumference of the notch, the button card is arranged on the button bracket, and the button cover is arranged on the notch. BRIEF DESCRIPTION OF THE DRAWINGS

[0064] The terms used in the implementation section of this application are only used to explain the specific embodiments of this application and are not intended to limit this application.

[0065] An electronic device provided in an embodiment of the present application may include, but is not limited to, a foldable fixed terminal or mobile terminal such as a mobile phone, a tablet computer, a laptop computer, an ultra-mobile personal computer (UMPC), a handheld computer, a touch-screen TV, a walkie-talkie, a netbook, a POS machine, a personal digital assistant (PDA), a wearable device, and a virtual reality device.

[0066] The electronic device can be folded into two layers or three layers, or can also be folded into more layers, and the folding method can be that the display screen folds inward, or the display screen folds outward, etc.

[0067] In the embodiment of the present application, the electronic device is a mobile phone, and the electronic device can be folded into two layers as an example for description.

[0068] Figure 1 This is a schematic diagram of the structure of an electronic device during the folding process provided by an embodiment of the present application. Figure 2 A schematic structural diagram of an electronic device in a folded state provided in an embodiment of the present application.

[0069] See also Figure 1 and Figure 2 As shown, the electronic device 100 includes a first housing 10 and a second housing 20, which are rotatably connected. The first housing 10 and the second housing 20 may be middle frames. The first end of the first housing 10 and the first end of the second housing 20 are rotatably connected. Specifically, the first housing 10 and the second housing 20 can achieve the rotatable connection via a hinge assembly, a rotating shaft, or a flexible board.

[0070] The first housing 10 and the second housing 20 can move toward each other, that is, fold relative to each other, and finally the first housing 10 and the second housing 20 abut against each other and fold relative to each other, so that the electronic device 100 is in a folded state. Figure 2 Alternatively, the first housing 10 and the second housing 20 may also move in opposite directions, that is, unfold relatively, and finally the first housing 10 and the second housing 20 are flattened and located in the same plane, so that the electronic device 100 is in the unfolded state.

[0071] Continue to see Figure 1 and Figure 2 As shown, a retractable snap-in member 11 is provided on the first housing 10, that is, the snap-in member 11 can be extended out of the first housing 10, or the snap-in member 11 can be retracted into the first housing 10. In the embodiment of the present application, the width direction of the electronic device 100 is the x-direction, and the thickness direction of the electronic device 100 is the z-direction. In other words, the snap-in member 11 can move along the x-direction, so that it can be retracted and arranged on the first housing 10, wherein the movement direction of the snap-in member 11 extending out of the first housing 10 is the +x-direction, and the movement direction of the snap-in member 11 retracting into the first housing 10 is the -x-direction.

[0072] The second housing 20 is provided with a snap-fitting position 21, into which the snap-fitting member 11 fits. When the first housing 10 and the second housing 20 move toward each other until the electronic device 100 is in the folded state, the snap-fitting member 11 extends out of the first housing 10 and locates within the snap-fitting position 21. The snap-fitting member 11 and the snap-fitting position 21 restrict relative movement between the first housing 10 and the second housing 20, thereby locking the first housing 10 and the second housing 20 together. This allows the electronic device 100 to remain in the folded state for extended periods of time, reduces the risk of the electronic device 100 unfolding due to minor touches or misoperation, and improves the user experience.

[0073] The first housing 10 is also provided with a button 12. When the button 12 is pressed, the direction of movement of the button 12 is the +z direction, and the opposite direction is the -z direction. When the electronic device 100 is to be unfolded, pressing the button 12 causes the latch 11 to retract into the first housing 10, thereby disengaging the latch 11 from the latching position 21. The first housing 10 and the second housing 20 are then rotated so that they move away from each other until the electronic device 100 is in the unfolded state.

[0074] In which, a side end cover 101 may be provided on the second end of the first shell 10, the second end of the first shell 10 is opposite to the first end of the first shell 10, and the second end of the second shell 20 is opposite to the first end of the second shell 20, and the button 12 and the snap-on member 11 may both be arranged on the end cover 101.

[0075] In addition, if Figure 1 and Figure 2 As shown in the figure, the camera 30 and the flash 40 of the electronic device 100 can also be set on the end cover 101, so that the camera 30 and the flash 40 can be reduced or avoided from being set on the display surface of the electronic device 100, which helps to increase the screen-to-body ratio of the electronic device 100 and realize full-screen display of the electronic device 100.

[0076] It should be understood that the electronic device 100 may also include other structural components to ensure that the functions of the electronic device 100 can be realized. Specifically, the electronic device 100 may also include: a processor, a memory, a sensor, a display screen, an antenna, etc.

[0077] In the related art, the linkage between the button and the clip is typically achieved through a cam structure and a rolling element. The cam structure can be positioned below the button, abutting against the rolling element with an inclined abutment surface. The rolling element is in rolling connection with the first end of the clip. When the button is pressed, the button pushes the cam structure to move vertically (+z), which in turn drives the rolling element to roll and move horizontally (-x). This causes the rolling element to move the first end of the clip, causing the clip to retract into the first housing, thereby disengaging the second end of the clip (the end opposite the first end) from the snap-on position, allowing the first and second housings to move relative to each other and expand.

[0078] An elastic member is also connected to the first end of the clipping member, one end of the elastic member is connected to the clipping member, and the other end of the elastic member abuts against the first shell. When the rolling member drives the clipping member to shrink into the first shell, the elastic member is compressed. When the button is released (the pressing force on the button is removed), the rebound force of the elastic member causes the clipping member to move in the opposite direction, and the other end of the clipping member extends out of the first shell, and the button returns to its original position.

[0079] However, the aforementioned drive method for moving the latching element has a relatively small transmission ratio and a narrow adjustment range, resulting in a longer stroke required to press the button, which degrades the pressing experience. Furthermore, the cam structure is typically large, and the drive structure formed with the rolling element takes up a lot of space and is inconvenient to install.

[0080] To address the aforementioned technical issues, embodiments of the present application provide an electronic device in which a button and a clip are linked via a transmission torsion spring, achieving controllable travel, a large transmission ratio, and an adjustable range. Furthermore, the transmission torsion spring, as a driving mechanism, is compact, occupies minimal space, facilitates assembly, and contributes to the slimmer design of the electronic device.

Figure 5 This is a schematic diagram of the structure of a transmission torsion spring provided in an embodiment of the present application. Figure 6 This is a schematic cross-sectional structure diagram of a first shell provided in an embodiment of the present application. Figure 7 This is a schematic diagram of an assembly of a button and a clip provided in an embodiment of the present application. Figure 8 This is a schematic diagram of the structure of an elastic torsion spring provided in an embodiment of the present application. Figure 9 A schematic diagram of the analysis of the forces acting on a transmission torsion spring and an elastic torsion spring provided in an embodiment of the present application.

[0082] See also Figure 3 As shown, a retractable clip 11 is provided on the first housing 10, and a button 12 is also provided on the first housing 10. Figure 4 As shown, a transmission torsion spring 13 is provided in the first housing 10 . Pressing the button 12 can move the transmission torsion spring 13 , which can drive the clamping member 11 to contract, thereby separating the clamping member 11 from the clamping position 21 .

[0083] Among them, such as Figure 3 As shown, the second end of the first shell 10 may have a first side surface 10a and a second side surface 10b. The first side surface 10a may be the side surface on the side end cover 101 of the first shell 10 facing the first end of the first shell 10. The second side surface 10b may be adjacent to the first side surface 10a. The second side surface 10b may be the end surface of the side end cover 101.

[0084] Specifically, the button 12 can be set on the second side 10b, the clip 11 can be located below the button 12 (in the +z direction), the first end 11a of the clip 11 is located inside the first shell 10, and the second end 11b of the clip 11 can extend from the first side 10a to the outside of the first shell 10, or retract into the first shell 10.

[0085] Specifically, in the embodiment of the present application, the transmission torsion spring 13 is located in the first housing 10, and the button 12 can be located above the transmission torsion spring 13 (in the +z direction), see Figure 5 As shown, the transmission torsion spring 13 includes a rotating end 132, an input end 131 and an output end 133, wherein the input end 131 and the output end 133 are respectively located on both sides of the rotating end 132 (spiral part), and the transmission torsion spring 13 is rotatably arranged in the first shell 10 through the rotating end 132.

[0086] For details, see Figure 6 and Figure 7 As shown, a fixed shaft 15 is disposed within the first housing 10, and the rotating end 132 of the transmission torsion spring 13 can be sleeved on the fixed shaft 15 and rotate relative to the fixed shaft 15. In this way, the input end 131 and the output end 133 located on either side of the rotating end 132 can rotate about the rotating end 132, forming a lever structure. The input end 131 of the transmission torsion spring 13 is slidably connected to the button 12, and the output end 133 of the transmission torsion spring 13 is connected to the clamping member 11.

[0087] Specifically, the button 12 may have a sliding groove 124, and the input end 131 of the transmission torsion spring 13 may be slidably disposed in the sliding groove 124, so that the input end 131 can slide in the sliding groove 124, thereby achieving a sliding connection between the input end 131 and the button 12. A mounting groove 111 may be formed on the first end 11a of the clamping member 11, and the output end 133 of the transmission button 12 may be fixedly disposed in the mounting groove 111, thereby achieving a fixed connection between the output end 133 and the clamping member 11.

[0088] When the button 12 is pressed, that is, a pressing force F in the +z direction is applied to the button 12, the button 12 moves in the +z direction. Figure 7 and Figure 9 As shown, the button 12 pushes the input end 131 to rotate around the rotation end 132, and the rotation trajectory of the input end 131 includes partial displacements along the +z direction and the +x direction. Figure 6 As shown, the rotation of the input end 131 drives the output end 133 to rotate around the rotating end 132. The rotation trajectory of the output end 133 is opposite to the trajectory of the input end 131, including partial displacements along the -z direction and the -x direction. The output end 133 can drive the first end 11a of the clamping member 11 to move along the -x direction, so that the clamping member 11 shrinks toward the first shell 10, and the second end 11b of the clamping member 11 is disengaged from the clamping position 21, so that the first shell 10 and the second shell 20 can be relatively unfolded.

[0089] The transmission torsion spring 13 is rotated by the rotating end 132, and the input end 131 and the output end 133 on both sides of the rotating end 132 are respectively connected to the button 12 and the clamping member 11. The transmission torsion spring 13 forms a lever structure, which can convert the small stroke of the input end 131 into a large stroke output. That is to say, the pressing stroke of the button 12 is small, so that the input end 131 of the transmission torsion spring 13 moves a small stroke. After the conversion of the transmission torsion spring 13, the output end 133 of the transmission torsion spring 13 can also move a large stroke, that is, the stroke that drives the clamping member 11 to shrink is large, so that the clamping member 11 can achieve a large stroke movement and disengage from the clamping position. It has a large transmission ratio, which can effectively reduce the pressing stroke required to press the button 12 and improve the pressing experience.

[0090] In addition, the small-stroke movement on the input end 131 is converted into a large-stroke movement on the output end 133, allowing the clamping member 11 to achieve a large-stroke contraction movement. This has a large adjustable range, which can easily increase the retractable range of the clamping member 11 and enable the retractable amount of the clamping member 11 to be adjusted within a large range. This helps to improve the engagement strength between the clamping member 11 and the engaging portion 21, ensuring the locking strength between the first shell 10 and the second shell 20 in the folded state. At the same time, by adjusting the shape of the transmission torsion spring 13, its transmission ratio can be adjusted, making it have a high degree of stroke controllability.

[0091] Furthermore, compared to existing cam structures and roller drive structures, the transmission torsion spring 13 is smaller in size, requires less space, is easier to install, and contributes to a slimmer design of the electronic device 100. Furthermore, the transmission torsion spring 13 is also simpler in structure, easier to implement, and helps reduce costs.

[0092] It should be noted that when the button 12 is not pressed, the input end 131 of the transmission torsion spring 13, the end facing away from the rotating end 132, is tilted toward the first side surface 10a of the first housing 10, and the end of the input end 131 adjacent to the rotating end 132 is tilted away from the first side surface 10a. The output end 133 of the transmission torsion spring 13, the end adjacent to the rotating end 132, is tilted toward the first side surface 10a of the first housing 10, and the end of the output end 133 facing away from the rotating end 132 is tilted away from the first side surface 10a. This facilitates the button 12 to push the input end 131 to rotate about the rotating end 132, thereby driving the clamping member 11 to retract via the output end 133, facilitating the implementation and enhancing the pressing experience.

[0093] When the pressing force on the button 12 is removed, the button 12 can rebound in a variety of ways. For example, an elastic member can be provided within the first housing 10, and the first end 11a of the clip 11 can abut against the inner wall of the first housing 10 through the elastic member. When the button 12 is pressed, the output end 133 of the transmission button 12 drives the clip 11 to retract into the first housing 10, compressing the elastic member. When the clip 11 is separated from the engaging portion 21, the button 12 is released, and the rebound force of the compressed elastic member can push the clip 11 in the opposite direction, causing the second end 11b of the clip 11 to extend out of the first housing 10, while simultaneously driving the output end 133 of the transmission torsion spring 13 to move, thereby pushing the button 12 back to its original position.

[0094] Alternatively, see Figure 7 and Figure 8 As shown, an elastic torsion spring 14 is also provided in the first shell 10. The elastic torsion spring 14 includes a connected fixed end 141 (spiral part) and an extended end 142. The elastic torsion spring 14 is arranged in the first shell 10 through the fixed end 141. Specifically, the fixed end 141 can be sleeved and fixed on the fixed shaft 15. The extended end 142 of the elastic torsion spring 14 is slidably connected to the button 12, and the extended end 142 can also be slidably set in the sliding groove 124.

[0095] The fixed end 141 of the elastic torsion spring 14 can be set on the fixed shaft 15 by bonding, welding, or fixing with fasteners such as screws, or the fixed end 141 can also be set on the fixed shaft 15 by other connection methods.

[0096] See also Figure 9 As shown, when the button 12 is pressed, a pressing force F in the +z direction is applied to the button 12, causing the button 12 to move in the +z direction. Figure 6 and Figure 7As shown, when the button 12 pushes the transmission torsion spring 13 to rotate, it also pushes the extending end 142 of the elastic torsion spring 14 to rotate. Since the fixed end 141 is fixedly arranged on the fixed shaft 15, the elastic torsion spring will be compressed and put into a compressed state.

[0097] When the engaging member 11 is separated from the engaging position 21, the button 12 is released and the pressing force applied to the button 12 is removed. The rebound force of the compressed elastic torsion spring 14 can push the button 12 to move in the opposite direction, that is, the button 12 moves along the -z direction, pushing the button 12 to return to its original position. At the same time, the button 12 drives the engaging member 11 to move through the transmission torsion spring 13, so that the second end 11b of the engaging member 11 extends out of the first shell 10.

[0098] Compared with the method of elastically abutting the second shell 20 through an elastic member at one end of the clamping member 11, since the button 12 applies force to the elastic member through the clamping member 11, the elastic member is located at the moving end of the secondary transmission member (clamping member 11), there is a problem of force transmission lag, which reduces the tactile feel of pressing the button 12.

[0099] An elastic torsion spring 14 is used to achieve the rebound of the button 12. The button 12 is connected to the extended end 142 of the elastic torsion spring 14, that is, the elastic torsion spring 14 is located on the pressing side. Pressing the button 12 directly acts on the elastic torsion spring 14, and the pressing feedback force is more obvious, which helps to improve the pressing feel of the button 12.

[0100] In addition, the use of a double torsion spring structure of the elastic torsion spring 14 and the transmission torsion spring 13 allows both to be located on the side of the button 12, which helps to improve the compactness of the structural distribution, further reducing the overall space occupied and facilitating installation.

[0101] The specific positions and numbers of the transmission torsion spring 13 and the elastic torsion spring 14 disposed within the second housing 20 can be selected and set according to actual needs. Specifically, the transmission torsion spring 13 and the elastic torsion spring 14 are both disposed on the fixed shaft 15. In the extension direction of the fixed shaft 15, an elastic torsion spring 14 can be disposed on both sides of the transmission torsion spring 13.

[0102] like Figure 7 As shown in the figure, a transmission torsion spring 13 and two elastic torsion springs 14 are provided on the fixed shaft 15. The elastic torsion springs 14 are located on both sides of the transmission torsion spring 13. This can balance the rebound force applied to the button 12, reduce or avoid the lateral flipping of the keycap 121 of the button 12, extend the service life and improve the user experience.

[0103] Among them, in one possible implementation, combined with Figure 6 and Figure 7As shown, the input end 131 of the transmission torsion spring 13 and the extended end 142 of the elastic torsion spring 14 are located on the same side of the button 12. Specifically, the input end 131 and the output end 133 can both be located on the side of the button 12 near the second end 11b of the clamping member 11. Positioning the input end 131 on the side of the button 12 near the second end 11b of the clamping member 11 facilitates the realization that when the button 12 is pressed, the input end 131 and the output end 133 are pushed to drive the clamping member 11 to retract into the first housing 10, thereby improving the pressing experience.

[0104] Figure 10 This is a schematic diagram of a disassembled structure of a first shell provided in an embodiment of the present application. Figure 11 This is a schematic diagram of the assembly of a slide member, a transmission torsion spring and an elastic torsion spring provided in an embodiment of the present application.

[0105] See also Figure 10 As shown, the first shell 10 has a receiving groove 102 , the notch 1021 of the receiving groove 102 is located on the second side surface 10 b of the first shell 10 , and the transmission torsion spring 13 , the elastic torsion spring 14 and the first end of the clamping member 11 are all located in the receiving groove 102 .

[0106] A button bracket 16 is also provided on the first housing 10. Specifically, Figure 4 As shown, the button bracket 16 can be set on the circumference of the notch 1021 of the accommodating groove 102, the button 12 can be clamped on the button bracket 16, and the button 12 is covered on the notch 1021, so that the button 12 is set on the first shell 10 through the button bracket 16.

[0107] The button bracket 16 is arranged around the notch 1021 of the accommodating groove 102. The button bracket 16 can be fixedly connected to the first shell 10 by bonding, welding, and threaded fastening. Alternatively, the button bracket 16 can be arranged on the first shell 10 by other connection methods.

[0108] The button 12 and the button bracket 16 can be connected by a snap-fit connection, which facilitates assembly. Specifically, a first snap-fitting member can be provided on the button 12, and a second snap-fitting member can be provided on the button bracket 16. The snap-fitting connection between the button 12 and the button 12 can be achieved by cooperating with the first snap-fitting member and the second snap-fitting member. For example, a first snap-fitting member can be provided on the circumferential outer wall of the button 12, and a second snap-fitting member can be provided on the circumferential inner wall of the button bracket 16. When the button 12 is provided on the button bracket 16, the side of the first snap-fitting member facing away from the snap-fitting member 11 can be brought into contact with the side of the second snap-fitting member facing the snap-fitting member 11, thereby preventing the button 12 from falling off the first housing 10, thereby achieving snap-fit fixation of the button 12 and the button bracket 16.

[0109] Alternatively, a first assembly groove may be provided on the button 12 and a second assembly groove may be provided on the button bracket 16 , and the button 12 and the button bracket 16 may be fixed by engaging a latch with the first assembly groove and the second assembly groove.

[0110] Alternatively, the button 12 and the button bracket 16 may be connected in other ways, which are not limited in the embodiment of the present application.

[0111] Continue to see Figure 10 As shown, the button 12 may include a key cap 121 and a slide member 122, wherein the slide member 122 is arranged on a side of the key cap 121 facing the clamping member 11, and is combined with the key cap 121 to form a plurality of slide members. Figure 6 As shown, a gap is provided between the slide member 122 and the keycap 121 to form a slide slot 124. The input end 131 of the transmission torsion spring 13 is rotatably disposed in the slide slot 124, and the extension end 142 of the elastic torsion spring 14 is also rotatably disposed in the slide slot 124. Specifically, both the input end 131 and the extension end 142 can be sleeved on the slide slot 124 and can slide in the slide slot 124, thereby achieving connection between the button 12 and the input end 131 of the transmission torsion spring 13, and between the button 12 and the extension end 142 of the elastic torsion spring 14.

[0112] Among them, see Figure 11 As shown, the slide groove part 122 may include a connecting portion 1221 and a slide groove portion 1222. The vertical height of the side of the slide groove portion 1222 facing the keycap 121 may be lower than the vertical height of the side of the connecting portion 1221 facing the keycap 121. The connecting portion 1221 is abutted against the keycap 121. In this way, since the vertical height of the side of the slide groove portion 1222 facing the keycap 121 is lower, there will be a gap between the slide groove portion 1222 and the keycap 121, thereby forming a sliding groove 124.

[0113] The connection between the connecting portion 1221 of the slide member 122 and the keycap 121 can be achieved in various ways. For example, the connecting portion 1221 and the keycap 121 can be connected by riveting, screwing, or other fasteners. Alternatively, the connecting portion 1221 and the keycap 121 can be connected by welding, bonding, or other methods. Alternatively, the connecting portion 1221 and the keycap 121 can be connected by other connection methods.

[0114] Specifically, such as Figure 10 As shown, an adhesive layer 123 can be provided between the connecting portion 1221 and the keycap 121, such as forming an adhesive layer 123 between the connecting portion 1221 of the slide member 122 and the keycap 121 by dispensing glue, and the connecting portion 1221 and the keycap 121 can be fixedly connected by the adhesive layer 123, which is low in cost and easy to assemble.

[0115] See also Figure 11As shown, a avoidance opening 1223 can also be opened on the sliding groove member 122. When the input end 131 and the extension end 142 are arranged in the sliding groove 124, the input end 131 and the extension end 142 can pass through the avoidance opening 1223 and be arranged in the sliding groove 124, so as to facilitate the assembly connection of the transmission torsion spring 13, the elastic torsion spring 14 and the button 12, and facilitate operation.

[0116] Figure 12 This is another schematic diagram of the partial structure inside the first shell provided in an embodiment of the present application. Figure 13 This is a schematic diagram of the structure of a transmission torsion spring provided in an embodiment of the present application. Figure 14 This is a schematic diagram of the structure of another elastic torsion spring provided in an embodiment of the present application. Figure 15 This is a schematic cross-sectional view of another first shell provided in an embodiment of the present application. Figure 16 This is another assembly diagram of a button and a clip provided in an embodiment of the present application. Figure 17 A schematic diagram of the analysis of the force applied to a transmission torsion spring provided in an embodiment of the present application.

[0117] In another possible implementation, see Figure 12 As shown, the input end 131 of the transmission torsion spring 13 and the extended end 142 of the elastic torsion spring 14 can be located on both sides of the button 12 (or the button bracket 16). Specifically, the input end 131 of the transmission torsion spring 13 is located on the side of the button 12 close to the second end 11b of the clamping member 11, and the extended end 142 of the elastic torsion spring 14 is located on the side of the button 12 away from the second end 11b of the clamping member 11. This can further improve the symmetry of the rebound force applied to the button 12, and further reduce or avoid the problem of lateral tilting of the keycap 121.

[0118] At the same time, distributing the input end 131 of the transmission torsion spring 13 and the extension end 142 of the elastic torsion spring 14 on both sides of the button 12 can increase the overall spatial arrangement, help further reduce the size, reduce the overall weight, and reduce the space occupied by the entire drive structure. Moreover, compared with the input end 131 and the extension end 142 being on the same side, Figure 13 and Figure 14 As shown, in a space of equal length, the two are located on both sides, which can increase the length of the input end 131 and the extension end 142, further enhance the rebound touch when pressing, make the pressing experience more comfortable, and further enhance the pressing experience.

[0119] Accordingly, see Figure 15 As shown, the transmission torsion spring 13 is rotatably arranged on the fixed shaft 15 , and the elastic torsion spring 14 is fixedly arranged on the fixed shaft 15 . In the extending direction of the fixed shaft 15 , the elastic torsion spring 14 can be arranged on both sides of the transmission torsion spring 13 .

[0120] See also Figure 16 and Figure 17 As shown, when the button 12 is pressed, that is, a pressing force F in the +z direction is applied to the button 12, the button 12 moves along the +z direction, and the button 12 pushes the input end 131 to rotate around the rotating end 132. The rotation trajectory of the input end 131 includes partial displacements along the +z direction and the +x direction.

[0121] Combine Figure 15 As shown, the rotation of the input end 131 drives the output end 133 to rotate around the rotating end 132. The rotation trajectory of the output end 133 is opposite to the trajectory of the input end 131, including partial displacements along the -z direction and the -x direction. The output end 133 can drive the first end 11a of the clamping member 11 to move along the -x direction, so that the clamping member 11 shrinks toward the first shell 10, and the second end 11b of the clamping member 11 is disengaged from the clamping position 21, so that the first shell 10 and the second shell 20 can be relatively unfolded.

[0122] Furthermore, as the button 12 rotates the transmission torsion spring 13, it also rotates the extended end 142 of the elastic torsion spring 14, compressing the elastic torsion spring 14. When the engaging member 11 is separated from the engaging portion 21, the button 12 is released. The rebound force of the compressed elastic torsion spring 14 pushes the button 12 in the opposite direction, that is, in the -z direction, returning it to its original position. Simultaneously, the button 12 drives the engaging member 11 via the transmission torsion spring 13, causing the second end 11b of the engaging member 11 to extend outside the first housing 10.

[0123] Figure 18 This is a schematic assembly diagram of another slide member, transmission torsion spring and elastic torsion spring provided in an embodiment of the present application.

[0124] The difference between the input end 131 and the extension end 142 being located on the same side of the button 12 is that, see Figure 18 As shown, the input end 131 and the extension end 142 are located on both sides of the button 12, and at least two slide members are provided in the first housing 10, such as a first slide member 122a and a second slide member 122b. Figure 15 As shown, the gap between the first slide member 122a and the keycap 121 forms a first slide slot 124a, and the input end 131 of the transmission torsion spring 13 is slidably disposed in the first slide slot 124a. The gap between the second slide member 122b and the keycap 121 forms a second slide slot 124b, and the extension end 142 of the elastic torsion spring 14 is slidably disposed in the second slide slot 124b.

[0125] It should be noted that the first chute member 122a and the second chute member 122b may each include a connecting portion and a chute portion. Each chute portion may be provided with an escape opening 1223. The specific number and position of the escape openings 1223 may be selected and set based on the number and position of the input ends 131 and the extension ends 142.
