[0044] The invention provides a key and an electronic device.

[0045] Please refer to Figure 1-Figure 4 The key comprises a key cap 10 and a key body 20,

[0046] The key cap 10 has a hollow structure opening downward, and a through hole 11 is provided on the top wall of the key cap 10;

[0047] The button body 20 is provided with a bracket 21 and a buckle body 22. The bracket 21 includes a bracket body 211 and a mounting portion 212. The button cap 10 is in contact with the bracket body 211 on one side thereof close to the bracket body 211.

[0048] The mounting portion 212 is provided with a rotation hole 213, and the buckle body 22 is provided with a rotation portion 221 which is hinged to the rotation hole 213;

[0049] like Figure 5 and Figure 7As shown, the side wall of the button cap 10 is provided with a locking boss 12 inwardly, and one end of the buckle body 22 is provided with a locking portion 222, and the locking portion 222 is engaged with the locking boss; the other end of the buckle body 22 is provided with a pressing portion 223, and the locking portion 222 and the pressing portion 223 are respectively arranged on both sides of the rotating portion 221, and the pressing portion 223 is arranged in the extension direction of the through hole 11.

[0050] In an embodiment of the present application, the button includes a button cap 10 and a button body 20, the button cap 10 has a hollow structure opening downward, the top wall of the button cap 10 is provided with a through hole 11, the button body 20 is provided with a bracket 21 and a buckle body 22, the bracket 21 includes a bracket body 211 and an installation portion 212, the side of the button cap 10 close to the bracket body 211 is in contact with the bracket body 211, and when the button cap 10 is pressed, the button cap 10 and the bracket body 211 move together along the pressing direction. The mounting portion 212 is provided with a rotation hole 213, and the buckle body 22 is provided with a rotation portion 221. The buckle body 22 and the mounting portion 212 are hingedly connected to the rotation portion 221 through the rotation hole 213, so that the buckle body 22 and the mounting portion 212 can rotate relative to each other; the side wall of the key cap 10 is provided with a locking boss 12 inwardly, and one end of the buckle body 22 is provided with a locking portion 222, and the locking portion 222 is locked with the locking boss; the other end of the buckle body 22 is provided with a pressing portion 223, and the pressing portion 223 is arranged in the extending direction of the through hole 11, and in the direction of the locking portion 11, the locking portion 223 is provided with a locking portion 223. When the key is to be disassembled, a thin needle can be passed through the through hole 11 on the key cap 10. After the thin needle is inserted into the through hole 11, it abuts against the pressing part 223, and by pressing the pressing part 223, the buckle body 22 is rotated with the rotating hole 213 as the rotation center. After the buckle body 22 rotates, the buckle part 222 and the buckle boss are disengaged from each other, so that the key cap 10 and the bracket 21 can be easily disengaged from each other. Through the above structure, the key can be easily installed and disassembled, thereby solving the problem of the key of the electronic device being difficult to disassemble in the prior art.

[0051] In an optional embodiment, if Figure 4As shown, the key body 20 includes at least two buckle bodies 22 and two mounting portions 212. Specifically, the two mounting portions 212 are arranged opposite to each other, and the two buckle bodies 22 are arranged opposite to each other and hinged to different mounting portions 212. The two pressing portions 223 are both arranged in the extension direction of the through hole 11. Specifically, in order to ensure the stability of the connection between the key cap 10 and the bracket body 211, the buckle portions 222 of the two buckle bodies 22 are buckled with the two buckle bosses of the key cap 10. In a specific embodiment, the two buckle bodies 22 are arranged opposite to each other. When the key is disassembled, a thin needle can be passed through the through hole 11 and abutted against the pressing parts 223 of the two buckle bodies 22, and the pressing parts 223 are pushed to rotate the buckle bodies 22. After the buckle bodies 22 rotate, the buckle parts 222 and the buckle bosses of the key caps 10 are disengaged from the buckled state, so that the key caps 10 are no longer restricted by the key body 20, and it is convenient for users to disassemble the key caps 10.

[0052] In an optional embodiment, a guide groove is provided on the surface of one side opposite to the two pressing portions 223. Specifically, when the pressing portion 223 is pressed by a fine needle, the buckle body 22 will rotate with the rotating hole 213 as the rotation center. In a specific embodiment, the button body 20 includes a plurality of buckle bodies 22, and the pressing portions 223 of the buckle bodies 22 are close to each other. When the plurality of buckle bodies 22 rotate together, the pressing portions 223 of the plurality of buckle bodies 22 will interfere with each other due to the short spacing, and thus cannot rotate. In order to avoid the above situation, a guide groove is provided on the surface of the side opposite to the pressing portion 223. When the buckle body 22 rotates, the guide groove provided on the pressing portion 223 can avoid the rotation trajectory of other pressing portions 223, thereby preventing the plurality of pressing portions 223 from interfering with each other when rotating together. It can be understood that the implementation method for preventing interference between the multiple pressing portions 223 is not limited to this. In another implementation, the surface on the opposite side of the pressing portion 223 can be set as a curved structure. When the multiple buckle bodies 22 rotate together, the pressing portions 223 of different buckle bodies 22 can rotate relatively along the curved structure. Compared with the pressing portion 223 having an angular structure, the curved structure can effectively avoid the problem of interference between different buckle bodies 22.

[0053] In an optional embodiment, if Figure 7 and Figure 8As shown, the key is further provided with a limiting boss 30, and the limiting boss 30 is provided in the hollow structure of the key cap 10 or on the bracket body 211. The limiting boss 30 is used to limit the rotation angle of the buckle body 22. In a specific embodiment, the limiting boss 30 is provided on the inner top wall of the key cap 10 and is provided on the rotation track of the buckle body 22. When the key is disassembled, the pressing part 223 is pushed by the fine needle to rotate the buckle body 22. When the key body 20 includes a plurality of buckles When the buckle body 22 is fixed to the buckle body 211, in order to prevent the fine needle from passing through the gaps between the multiple pressing parts 223 after pushing the pressing part 223 to rotate, the rotation angle of the buckle body 22 can be limited by the limiting boss 30. Since the limiting boss 30 is arranged on the rotation track of the buckle part 222, the buckle body 22 will abut against the limiting boss 30 when it rotates, and the limiting boss 30 prevents the buckle body 22 from continuing to rotate, thereby preventing the fine needle from passing through the gaps between the multiple pressing parts 223. It can be understood that the setting position of the limiting boss 30 is not limited to this. In another specific embodiment, the limiting boss 30 can also be arranged on the bracket body 211, and the limiting boss 30 is arranged on the rotation track of the pressing part 223.

[0054] In an optional embodiment, a limiting portion 214 is provided on the mounting portion 212. Specifically, the setting direction of the limiting portion 214 is similar to or the same as the setting direction of the buckle body 22, and the limiting portion 214 is provided on a side of the buckle body 22 close to the bracket body 211 or a side away from the bracket body 211. When the buckle body 22 rotates to a certain angle, the buckle body 22 abuts against one side edge of the limiting portion 214, thereby limiting the rotation angle of the buckle body 22 by the limiting portion 214.

[0055] In an optional embodiment, the button body further includes a first elastic member 40 , one end of which is connected to the buckle body 22 , and the other end of which is connected to the inner wall of the button cap 10 or the bracket body 211 .

[0056] In a specific embodiment, one end of the first elastic member 40 abuts against a side surface of the bracket body 211 close to the key cap 10, and the other end abuts against a side surface of the pressing portion 223 close to the bracket body 211. In a specific embodiment, the buckle portion 222 is a boss structure extending toward one side of the side wall of the key cap 10, and a side surface of the boss structure close to the bracket body 211 abuts against a side surface of the buckle boss away from the bracket body 211. In order to ensure the stability of the abutment between the buckle portion 222 and the buckle boss, the first elastic member 40 provides the pressing portion 223 with an elastic force in a direction away from the bracket body 211. Under the action of the elastic force of the first elastic member 40, the buckle body 22 increases the force of the buckle portion 222 abutting against the buckle boss, thereby improving the stability of the abutment between the buckle portion 222 and the buckle boss.

[0057] In a preferred embodiment of the above embodiment, Figure 6-Figure 10 The bracket body 211 is also provided with a pressing groove 215, and the first elastic member 40 is accommodated in the pressing groove 215. The pressing groove 215 is used to limit the movement of the first elastic member 40 along the axial direction of the first elastic member 40. Specifically, the inner diameter of the pressing groove 215 is larger than the diameter of the first elastic member 40, so as to ensure that the first elastic member 40 can be elastically deformed in the pressing groove 215. When the button body 20 includes a plurality of the buckle bodies 22 and a plurality of the mounting portions 212, the pressing groove 215 is provided between the plurality of the mounting portions 212, and the first elastic member 40 is provided in the pressing groove 215. One end of the first elastic member 40 abuts against the bottom wall of the pressing groove 215, and the other end abuts against the pressing portions 223 of the plurality of the buckle bodies 22. The first elastic member 40 provides an elastic force for the pressing portion 223 in a direction toward one side of the bottom wall away from the pressing groove 215, so that the buckle portion 222 of the buckle body 22 abuts against the buckle boss under the action of the lever, thereby increasing the connection stability between the button cap 10 and the button body 20. In addition, by setting the pressing groove 215, it is convenient to limit the first elastic member 40, so that the assembler of the button can position the first elastic member 40 according to the pressing groove 215 when assembling the first elastic member 40, thereby improving the assembly efficiency of the button.

[0058] In an optional embodiment, if Figure 4 and Figure 5As shown, the bracket 21 further includes a stop portion 216, a stop plate 224 is provided on one side of the buckle body 22 close to the bracket body 211, the stop portion 216 has a stop hole for accommodating the stop plate 224, the stop plate 224 is inserted into the stop hole, and specifically, a surface of the stop plate 224 on one side away from the bracket body 211 abuts against an inner wall of the stop hole on one side away from the bracket body 211. In a specific embodiment, when the pressing portion 223 of the buckle body 22 abuts against the first elastic member 40, the radial component of the rotational force generated downward by the pressing portion 223 of the buckle body 22 along the first elastic member 40 is equal to the elastic force of the first elastic member 40. When the button cap 10 is disassembled, in order to prevent the pressing portion 223 from being excessively moved upward or downward when the fine needle presses the pressing portion 223, a stop portion 216 is provided on the bracket body 211, and a stop plate 224 is provided on the pressing portion 223. The stop plate 224 is received in the through hole 11 or the blind hole formed by the stop portion 216. When the pressing portion 223 is pressed by the fine needle, the stop plate 224 and the stop portion 216 are close to the bracket body 211. The first elastic member 40 abuts against one side of the stop plate 224, thereby limiting the further movement of the stop plate 224 toward the side of the bracket body 211, thereby limiting the rotation of the buckle body 22; when the fine needle is not used to press the pressing portion 223, the first elastic member 40 provides an elastic force to the pressing portion 223 away from the pressing groove 215, so that the stop plate 224 abuts against the inner side wall of the stop portion 216 away from the bracket body 211, thereby avoiding the problem of an empty stroke between the key cap 10 and the key body 20.

[0059] Optionally, in another specific embodiment, Fig. 9 The button body may further include a second elastic member 70, one end of the second elastic member 70 is connected to the bracket body 211, and the other end is connected to the buckle body 22, and the connection position with the buckle body 22 is located between the buckle portion 222 and the rotating portion 221. The second elastic member 70 provides a pulling force for the buckle body 22, so that the buckle portion 222 of the buckle body 22 generates a force to move toward the bracket body 211, thereby increasing the abutment force between the buckle portion 222 and the buckle boss, thereby increasing the stability of the connection between the buckle portion 222 and the buckle boss.

[0060] It is understandable that the configuration of the second elastic member 70 is not limited thereto. In another specific embodiment, Fig.10The second elastic member 70 can also be connected to the inner side wall or the inner top wall of the button cap 10 at one end and connected to the buckle body 22 at the other end, and the connection position with the buckle body 22 is located between the rotating part 221 and the pressing part 223. The second elastic member 70 provides a pulling force for the buckle body 22, so that the pressing part 223 can move toward the side close to the button cap 10, and the buckle part 222 moves toward the side close to the bracket body 211 under the action of the lever, thereby increasing the abutment force between the buckle part 222 and the buckle boss, thereby increasing the stability of the connection between the buckle part 222 and the buckle boss.

[0061] To achieve the above purpose, the present application proposes an electronic device, which includes a housing 60, a key switch 60, and a key as described in any one of the above embodiments, wherein the housing 60 is provided with a key hole 61, the key cap 10 is received in the key hole 61, the key cap 10 can move relative to the key hole 61, and the side of the key body 20 away from the key cap 10 abuts against the key switch 60. Specifically, the key switch 60 is provided on the side of the key body 20 away from the key cap 10, and when the key cap 10 is pressed, the key body 20 and the key cap 10 move together in the pressing direction, and the key switch 60 abutting against the key body 20 is pressed, thereby triggering the key switch 60 and realizing the function corresponding to the key.

[0062] In an optional embodiment, a fixing portion 62 is provided on the inner wall of the shell 60, and a support arm 217 is provided on one side of the fixing portion 62 of the support arm 21 of the button, and one end of the support arm 217 away from the support body 211 is connected to the fixing portion 62. Specifically, when the button is pressed, the button cap 10 and the support body 211 move together in the pressing direction. In order to ensure the rebound of the button, the support arm 217 protruding outward from the support body 211 can be fixedly connected to the fixing portion 62. When the button is pressed, the support arm 217 undergoes elastic deformation. After the pressing is completed, the button cap 10 and the support body 21 return to their initial positions under the elastic force of the support arm 217. It is understandable that the connection method between the bracket 21 and the fixing portion 62 is not limited to this. In another specific embodiment, the electronic device also includes a reset spring, and the reset spring is sleeved on the fixing portion 62 or is arranged on the side of the shell 60 away from the bracket 21. When the button is pressed, the reset spring undergoes elastic deformation. When the pressing is completed, the button returns to its initial position under the elastic force of the reset spring, thereby avoiding the problem that the button cannot return to its initial position after being pressed.
