[0040] The application will be described in detail below with reference to specific drawings and examples:

[0041] Please refer to Figure 1 The application provides a key structure for installation on an electronic device for a user to press to achieve a corresponding control operation. For example, when the key structure is applied to a handle, the key structure can be pressed by a user to press the key 20 through the pressing structure 30, and then trigger the related circuit on the circuit board 10 through the key 20 to achieve the corresponding control operation of the handle. In addition, the key structure can also be applied to a remote controller, a keyboard and other devices.

[0042] Please refer to Figure 1 and Figure 2 The key structure includes a circuit board 10, a key 20, a pressing structure 30 and a first elastic member 40. The key 20 is arranged on the circuit board 10. The pressing structure 30 is arranged opposite to the key 20. The pressing structure 30 is used to press the key 20 under an external force to make the key 20 trigger the circuit board 10. The first elastic member 40 is arranged between the pressing structure 30 and the circuit board 10. The first elastic member 40 is arranged around the outer periphery of the key 20.

[0043] The key 20 refers to a component that can be triggered by pressing, touching and the like to turn on the related circuit on the circuit board 10. For example, in this embodiment, the key 20 can be a micro switch or a spring sheet and the like.

[0044] The pressing structure 30 refers to a structure for bearing the external force applied by a user and capable of deforming or moving under the external force.

[0045] As an example, the pressing structure 30 can deform towards the key 20 under the external force to press the key 20. For example, the pressing structure 30 can be a spring sheet structure. Alternatively, the pressing structure 30 can also move towards the key 20 under the external force to press the key 20. For example, the pressing structure 30 can be a key cap. Of course, the pressing manner of the pressing structure 30 when pressing the key 20 is not limited to the above two, but can also be other forms, which will not be described here.

[0046] Among them, the circuit board 10 can be provided with a conductive part such as a solder pad. When the key 20 is pressed, at least part of the structure of the key 20 approaches the circuit board 10 and contacts the conductive part on the circuit board 10, so that the circuit on the circuit board 10 is closed. When the external force acting on the key 20 is removed, the above structure of the key 20 is away from the circuit board 10 and is separated from the conductive part on the circuit board 10, so that the circuit is disconnected.

[0047] The first elastic member 40 can be made of materials such as rubber and silicone that can elastically deform. The shape of the first elastic member 40 can be sheet-shaped or columnar and the like.

[0048] The pressing structure 30 is arranged opposite to the key 20 along a first direction Z, and the first elastic member 40 is abutted between the pressing structure 30 and the circuit board 10 along the first direction Z, and the first elastic member 40 can be elastically deformed along the first direction Z.

[0049] The first elastic member 40 surrounding the outer periphery of the key 20 means that the first elastic member 40 is arranged on the outer periphery side of the key 20 around the first axis L1. Wherein, the first axis L1 is as the axis L1 shown in Figure 2 Figure 2 The X-axis, Y-axis and Z-axis are also shown in Figure 2 The first direction Z is parallel to the Z-axis, and the first axis L1 is also parallel to the Z-axis, so the first direction Z is parallel to the first axis L1.

[0050] Specifically, when the pressing structure 30 presses the key 20, the pressing structure 30 will compress the first elastic member 40, and then the first elastic member 40 will accumulate elastic potential energy. After the external force acting on the pressing structure 30 is removed, the first elastic member 40 releases the elastic potential energy and drives the pressing structure 30 to move away from the circuit board 10, so that the pressing structure 30 is separated from the key 20, and then the key 20 can be separated from the circuit board 10, so that the related circuit on the circuit board 10 is disconnected.

[0051] The key structure provided by the embodiment of the application is that the key 20 is arranged on the circuit board 10, and the pressing structure 30 is arranged opposite to the key 20. When a user presses the pressing structure 30, the pressing structure 30 can press the key 20 to trigger the circuit board 10 and realize the conduction of the related circuit on the circuit board 10. The first elastic member 40 is abutted between the pressing structure 30 and the circuit board 10, and surrounds the outer periphery of the key 20, so that when the pressing structure 30 presses the key 20, the first elastic member 40 can buffer the pressing stroke between the pressing structure 30 and the key 20 by the elastic deformation of the first elastic member 40. In the case of removing the external force, the first elastic member 40 can also elastically deform and push the pressing structure 30 away from the key 20, so that the key 20 can be separated from the circuit board 10, and the related circuit on the circuit board 10 is disconnected. Therefore, by arranging the first elastic member 40, the pressing action of the pressing structure 30 on the key 20 is more gentle, and the use feeling of the key structure is optimized.

[0052] In some embodiments, the key 20 is a spring structure. The key 20 and the circuit board 10 form a deformation space (not shown) therebetween. The deformation space is used for the elastic deformation of the key 20.

[0053] The shape of the spring structure can be circular, cross-shaped, quadrilateral, etc.​

[0054] The material of the elastic sheet can be, but is not limited to, a sheet structure made of stainless steel or the like having electrically conductive performance and good elastic performance.

[0055] As an example, as shown in Figure 2 , the elastic sheet structure can be arranged to protrude in the first direction Z towards a direction away from the circuit board 10 to form a deformation space with the circuit board 10 in the first direction Z. The key 20 can be elastically deformed in the first direction Z.

[0056] In use of the key structure, the pressing structure 30 can be pressed on the elastic sheet structure when subjected to an external force, so that the elastic sheet structure is deformed in the first direction Z, and after deformation, the elastic sheet structure can compress the deformation space until the elastic sheet structure abuts against the circuit board 10 and is in conduction with the conductive part on the circuit board 10, realizing the conduction of the related circuit on the circuit board 10. After the external force is removed, the elastic sheet structure can rebound in the first direction Z towards a direction away from the circuit board 10, the deformation space increases, and the elastic sheet structure is away from the circuit board 10, so that the related circuit on the circuit board 10 is disconnected.

[0057] In this way, the key 20 is an elastic sheet structure, which abuts against the circuit board 10 to realize circuit conduction under pressing, and rebounds and disconnects the related circuit on the circuit board 10 when the pressing force is removed. The key 20 has a simple structure and good rebound performance, and improves the working efficiency of the key 20 when triggering or disconnecting the circuit board 10.

[0058] In some embodiments, referring to Figures 1 to 3 , the key 20 includes a first elastic part 21 and a limiting part 22. The limiting part 22 is connected to the first elastic part 21. The first elastic part 21 is arranged opposite to the circuit board 10. The first elastic part 21 forms a deformation space with the circuit board 10. A first elastic member 40 is arranged around the outer periphery of the first elastic part 21. The first elastic member 40 is provided with a limiting groove 41 limiting the limiting part 22 in the circumferential direction. The pressing structure 30 is arranged opposite to the first elastic part 21.

[0059] Specifically, as shown in Figure 2 , the first elastic part 21 is arranged opposite to the circuit board 10 in the first direction Z. The first elastic part 21 can be arranged to protrude in the first direction Z away from the circuit board 10 to form a deformation space with the circuit board 10.

[0060] The first elastic member 40 arranged around the outer periphery of the first elastic part 21 means that the first elastic member 40 is arranged on the outer periphery side of the first elastic part 21 around the first axis L1.

[0061] As an example, the limiting portion 22 can be a protrusion, a column, or the like. During installation, the limiting portion 22 can be inserted into the limiting groove 41 in a plug-in manner and be circumferentially limited between the groove walls of the limiting groove 41. Here, the circumferential limitation refers to that, in the direction around the first axis L1, the limiting portion 22 is limited between the opposite two side walls of the limiting groove 41. In this way, the key 20 and the first elastic member 40 are difficult to rotate relative to each other around the first axis L1.

[0062] The number of the limiting portions 22 can be set to be multiple, and the multiple limiting portions 22 are arranged at the outer circumferential side of the first elastic portion 21 around the first axis L1. Correspondingly, the first elastic member 40 is also provided with multiple limiting grooves 41, and the multiple limiting grooves 41 are arranged at intervals along the first axis L1, and each limiting portion 22 is correspondingly limited in each limiting groove 41.

[0063] In use of the key structure, the user presses the pressing structure 30, and the pressing structure 30 can press on the first elastic portion 21 when pressed, so that the first elastic portion 21 can be deformed under force in the first direction Z, and after deformation, the first elastic portion 21 can abut on the circuit board 10 and be in conduction with the conductive part on the circuit board 10, so as to realize the conduction of the related circuit on the circuit board 10. After the external force is removed, the first elastic portion 21 can rebound towards the direction away from the circuit board 10 in the first direction Z, and then the related circuit on the circuit board 10 is disconnected.

[0064] In this way, when the key 20 is pressed, the key 20 is not easy to rotate relative to the first elastic member 40 around the circumference, which is beneficial to the stable triggering of the key 20 to the circuit board 10, and in use, the position of the key 20 on the circuit board 10 is not easy to deviate, which is beneficial to the accurate alignment of the pressing structure 30 to the key 20.

[0065] In some embodiments, the key 20 is a dome key.

[0066] The thickness of the dome key is usually small, so the installation space occupied by the dome key is small during installation. At the same time, the dome key has a simple structure and good conduction performance, which can achieve a good triggering effect between the pressing structure 30 and the circuit board 10. In addition, the dome key has stable rebound force, which optimizes the pressing feeling of the user during pressing.

[0067] In some embodiments, referring to Figure 1 and Figure 2 , the pressing structure 30 includes a second elastic member 31 and a pressing assembly 32. The second elastic member 31 is arranged on the circuit board 10. Part of the second elastic member 31 is arranged between the key 20 and the pressing assembly 32. The second elastic member 31 is used to press the key 20 under the pressing action of the pressing assembly 32. The first elastic member 40 abuts between the second elastic member 31 and the circuit board 10.

[0068] The second elastic member 31 can be, but is not limited to, a rubber pad, a silica gel pad, or the like.

[0069] Part of the second elastic member 31 is arranged between the key 20 and the pressing assembly 32 along the first direction Z. In use, the user presses the pressing structure 30, and the pressing structure 30 can press the second elastic member 31 when pressed. The second elastic member 31 elastically deforms along the first direction Z towards the key 20 after being pressed, so as to press the key 20 and trigger the circuit board 10. After the external force is removed, the pressing structure 30 moves away from the second elastic member 31 along the first direction Z, the second elastic member 31 rebounds and moves away from the key 20, so that the key 20 is disconnected with the related circuit on the circuit board 10.

[0070] Therefore, the second elastic member 31 can buffer the pressing stroke between the pressing structure 30 and the key 20 through the elastic deformation of itself, so that the pressing action of the pressing structure 30 on the key 20 is more gentle, and the use feeling of the key structure is optimized. At the same time, the arrangement of the second elastic member 31 avoids the direct contact between the key 20 and the pressing structure 30 as much as possible, reduces the risk of wear of the key 20 caused by the pressing structure 30, and improves the service life of the key 20.

[0071] In some embodiments, referring to Figures 2 to 4 The second elastic member 31 includes a main body part 311, a second elastic part 312, and an abutting part 313. The main body part 311 is arranged on the circuit board 10. The first elastic member 40 is arranged between the circuit board 10 and the main body part 311. The second elastic part 312 is arranged on the main body part 311. The second elastic part 312 protrudes from the main body part 311 on the side away from the circuit board 10. The second elastic part 312 is arranged opposite to the pressing assembly 32. The second elastic part 312 is provided with a groove 3121 on the side close to the circuit board 10. The abutting part 313 is arranged in the groove 3121. The abutting part 313 is also arranged opposite to the key 20.

[0072] In the first direction Z, the second elastic part 312 is arranged opposite to the pressing assembly 32, and the abutting part 313 is arranged opposite to the key 20. In use, the user presses the pressing structure 30, and the pressing structure 30 can press the second elastic part 312 protruding from the main body part 311 when pressed. The second elastic part 312 moves relative to the main body part 311 along the first direction Z towards the recess 3121 under the force. The abutting part 313 located in the recess 3121 moves along the first direction Z towards the outside of the recess 3121 under the driving of the second elastic part 312, and extends out of the recess 3121, until pressing the key 20, so that the key 20 triggers the circuit board 10. After the external force is removed, the pressing structure 30 moves away from the second elastic part 312 along the first direction Z, the second elastic part 312 rebounds and moves away from the recess 3121, and then the abutting part 313 moves away from the key 20 along the first direction Z and is accommodated in the recess 3121, so that the key 20 is disconnected with the related circuit on the circuit board 10.

[0073] In some embodiments, the number of the second elastic parts 312 can be set to be multiple, and the multiple second elastic parts 312 are distributed on the main body part 311 at intervals. Correspondingly, the number of the abutting parts 313 can also be set to be multiple, and each abutting part 313 is arranged in the recess 3121 of each second elastic part 312.

[0074] It should be noted that the abutting part 313 moves a certain stroke in the recess 3121 of the second elastic part 312 during pressing the key 20, so as to buffer the movement of the pressing structure 30, so that the user has a certain sense of segmentation when pressing the pressing structure 30, thereby optimizing the use feeling of the key structure.

[0075] In some embodiments, please refer to Figures 2 to 4 The pressing assembly 32 comprises a connecting piece 321 and a key shell 322. The second elastic part 31 is arranged between the circuit board 10 and the connecting piece 321. The key shell 322 is detachably connected with the connecting piece 321. At least part of the key shell 322 is arranged at the end of the connecting piece 321 away from the second elastic part 31.

[0076] The key shell 322 can be designed into any shape such as rectangle, triangle, cross, etc. according to actual needs.

[0077] The connecting piece 321 and the key shell 322 can be detachably connected by magnetic attraction, clamping, bonding or the like. As an example, the connecting piece 321 is provided with a first clamping piece 3211, the key shell 322 is provided with a second clamping piece 3221, and the connecting piece 321 and the key shell 322 can be fixed by clamping of the first clamping piece 3211 and the second clamping piece 3221, so as to avoid relative displacement or relative rotation of the key shell 322 and the connecting piece 321 during pressing of the key structure, and ensure assembly stability of the pressing structure 30. The first clamping piece 3211 and the second clamping piece 3221 can be buckles, clamps or the like.

[0078] In this way, the connecting piece 321 and the key shell 322 are detachably connected, and when the user needs to replace the key shell 322 of other shapes and sizes, the key shell 322 can be simply and conveniently detached from the connecting piece 321. Meanwhile, when the key shell 322 is damaged, it can also be conveniently detached for repair, improving the convenience of repair and replacement of the key shell 322.

[0079] In some embodiments, the connecting piece 321 and the key shell 322 can be limited relative to each other along the first axis L1. As shown in Figure 4 The connecting piece 321 is provided with a plug-in block 3213, and the key shell 322 is provided with a slot 3222. The connecting piece 321 and the key shell 322 can be connected by mutual plugging of the plug-in block 3213 and the slot 3222, so as to limit the relative rotation of the connecting piece 321 and the key shell 322 around the first axis L1. In this way, the relative rotation of the connecting piece 321 and the key shell 322 around the first axis L1 during pressing of the key structure is avoided as much as possible, and the assembly stability of the pressing structure 30 is ensured.

[0080] In some embodiments, as shown in Figure 4 The side of the connecting piece 321 facing the second elastic piece 31 is provided with a protruding portion 3212. The protruding portion 3212 can be a protruding block, a protruding point or the like. When the key shell 322 is pressed, the key shell 322 can drive the connecting piece 321 to move, and then press the second elastic piece 31. The protruding portion 3212 makes the pressing effect of the connecting piece 321 on the second elastic piece 31 better, reduces the poor contact between the connecting piece 321 and the second elastic piece 31, and is conducive to accurate pressing of the second elastic piece 31 on the key 20.

[0081] In some embodiments, as shown in Figures 1 to 4 The key 20 is provided in plurality. The plurality of keys 20 are arranged at intervals in the circumferential direction. The first elastic piece 40 is provided in plurality. Each first elastic piece 40 surrounds the outer periphery of each key 20.

[0082] The circumferential direction of the plurality of keys 20 refers to the direction around the second axis L2, which is the axis L2 shown in the middle of the figure, and the axis L2 is parallel to the Z axis. Each first elastic member 40 is arranged around the outer periphery of each key 20 along the first axis L1, which is parallel to the Z axis, and the axis L2 is parallel to the axis L1, and the first axis L1 is parallel to the second axis L2. Figure 2

[0083] Specifically, the specific number of keys 20 and the distribution of the plurality of keys 20 around the circumferential direction on the circuit board 10 can be selected according to the actual product used.

[0084] Therefore, when the user presses the pressing structure 30, the user can press different keys 20 through the pressing structure 30 by pressing the pressing structure 30 at different angles, and then turn on different circuits on the circuit board 10 through different keys 20 to achieve different control operations. In this way, the control function diversity and operation convenience of the key structure are greatly improved.

[0085] In some embodiments, referring to Figure 2 , the number of keys 20 is four. Among them, the distance between the centers of the two non-adjacent keys 20 is in the range of 15-18 mm.

[0086] As an example, when the key structure is applied to a handle, the four keys 20 can be used to trigger different circuits on the circuit board 10. In use, the user can replace the pressing of different keys 20 by manually adjusting the pressing position of the finger on the pressing structure 30 to execute different control operations by turning on different circuits.

[0087] In this way, when the distance between the centers of the two non-adjacent keys 20 is in the above range, the user has a better feeling when replacing the pressing of different keys 20, thereby optimizing the use experience of the key structure.
