Please refer to fig. 1 to fig. 5, the present invention provides a key 100.

In an embodiment of the present invention, the key 100 includes a mounting base 10, a pressing member 30 and a sounding elastic member 50; wherein, the pressing piece 30 is arranged on the mounting base 10 in a lifting way; the sounding elastic piece 50 comprises a spiral section 51 and a torsion arm section 53, the spiral section 51 is arranged on the mounting seat 10, the direction that the spiral section 51 extends from one end to the other end in a spiral mode is defined as a spiral extending direction, the spiral extending direction of the spiral section 51 and the lifting direction of the pressing piece 30 are arranged in an acute angle mode, and the torsion arm section 53 is connected to one end of the spiral section 51 and arranged in an included angle mode with the spiral extending direction of the spiral section 51; when the pressing member 30 is pressed and driven, the torsion arm section 53 is driven by the pressing member 30 to rotate around the extending direction of the spiral section 51, and collides with the mounting seat 10 when elastically returning.

In an embodiment of the present invention, the mounting base 10 may be used to mount and bear the pressing member 30, the sounding elastic member 50, and the like, and may be mounted on a keyboard body of a keyboard. Therefore, each part of the keyboard can be integrally formed and can be arranged on the keyboard body at one time, and the convenience of assembling the keyboard is improved. The projection of the mounting seat 10 on the horizontal plane may be substantially square, so that the shape is regular and the forming and manufacturing are convenient. Of course, the present application is not limited thereto, and the mount 10 may be provided in a substantially circular shape or an elliptical shape in a projection on a horizontal plane. In order to reduce the overall weight of the key 100 and make the keyboard portable, the material of the mounting seat 10 may be plastic material, for example: ABS, POM, PS, PMMA, PC, PET, etc. Of course, in order to prolong the service life of the key 100, the material of the mounting seat 10 may be a metal material, for example: stainless steel materials, aluminum alloy materials, copper alloy materials, iron alloy materials and the like. The pressing member 30 may be used to implement the function of the key 100 by a pressing action to input information such as letters, symbols or numbers. The working principle can be as follows: the pressing member 30 descends to block or conduct the optical path between the optical transmitter and the optical receiver on the keyboard body, and at this time, the control circuit board in the keyboard body of the keyboard can detect the blocking or conducting of the optical signal to realize the function of the key 100. The following steps can be also included: the pressing member 30 descends to abut against a contact switch on the keyboard body of the keyboard, and at this time, the control circuit board in the keyboard body of the keyboard can detect a trigger signal of the contact switch to realize the function of the key 100. Of course, the installation base 10 of the key 100 may be provided with a relevant light emitter, or contact switch, etc., which is not limited in the present application, and the key 100 may be ensured to realize the function of the key 100. Since the principle of the key 100 realizing the function of the key 100 by pressing is prior art, it will not be described in detail here. The sounding elasticity is because including spiral section 51 and torque arm section 53, and torque arm section 53 and the spiral extending direction of spiral section 51 are the contained angle setting for keep having elastic force between this torque arm section 53 and the spiral section 51. That is, when the torque arm section 53 is driven by the pressing member 30 to descend, it can rotate around the spiral extending direction of the spiral section 51; when the pressing member 30 is not abutted to and drives the pressing member 30, the torsion arm section 53 can rotate around the spiral extending direction of the spiral section 51 in the opposite direction under the driving of the deformation elastic force to collide with the mounting seat 10.

The utility model discloses a technical scheme's button 100 descends for mount pad 10 through drive pressing piece 30 when being pressed, can drive the torsion arm section 53 of sound production elastic component 50 and rotate and the sound production is out of shape around the extending direction of spiral section 51. The torsion arm section 53 may then collide with the mounting base 10 upon resilient return, thereby sounding a cue to alert the user that the key 100 has been effectively depressed. In addition, since the spiral extending direction of the spiral section 51 of the sounding elastic member 50 and the lifting direction of the pressing member 30 are arranged at an acute angle in the present embodiment, the torsion arm section 53 rotates back and forth only around the extending direction of the spiral section 51. So compare in prior art in the sound production elastic component 50 of button 100 at driven and the in-process that resets up, down, left and right each direction all has the removal, and make the relatively more weak simultaneous action of sound production elastic component 50 of this button 100 and button 100's collision strength, the elastic force and the deformation elastic force of the in-process itself that the swing arm section 53 in this scheme was driven and reset are located same straight line all the time, make this swing arm section 53 can take place stronger collision with mount pad 10 and reduce required removal action simultaneously, thereby the sound production suggestion effect and the life of this sound production elastic component 50 have been improved.

Referring to fig. 3, fig. 4 and fig. 5, in an embodiment of the present invention, an included angle between a spiral extending direction of the spiral section 51 and a lifting direction of the pressing member 30 is defined as α, which satisfies a relationship: alpha is more than or equal to 40 degrees and less than or equal to 50 degrees.

It can be understood that when the included angle α between the spiral extending direction of the spiral segment 51 and the lifting direction of the pressing member 30 is less than 40 °, the distance between the torsion arm segment 53 and the pressing member 30 is relatively small, which affects the rotation stroke of the torsion arm segment 53 when being driven by the pressing member 30, and affects the collision strength between the subsequent torsion arm segment 53 and the mounting seat 10. When the included angle α between the spiral extending direction of the spiral section 51 and the lifting direction of the pressing element 30 is greater than 40 °, the distance between the torsion arm section 53 and the pressing element 30 is relatively large, which causes the sounding elastic element 50 and the pressing element 30 to occupy a relatively large space in the mounting base 10, resulting in a relatively large overall size of the key 100. Therefore, the included angle alpha between the spiral extending direction of the spiral section 51 and the lifting direction of the pressing piece 30 is set to be more than or equal to 40 degrees and less than or equal to 50 degrees, so that the collision strength between the installation seats 10 when the torsion arm section 53 is elastically reset is ensured, and the compactness of distribution between the two is considered. Specifically, the included angle α between the spiral extending direction of the spiral segment 51 and the lifting direction of the pressing piece 30 may be 40 °, 41 °, 42 °, 43 °, 44 °, 45 °, 46 °, 47 °, 48 °, 49 °, 50 °, or may be any value in the above range.

It can be understood that, the pressing element 30 and the sounding elastic element 50 are both disposed in the accommodating cavity 10a of the mounting base 10, and the cavity wall of the accommodating cavity 10a can protect the pressing element 30 and the sounding elastic element 50 to some extent, so as to reduce the possibility that the pressing element 30 and the sounding elastic element 50 are damaged by foreign objects, thereby being beneficial to prolonging the service life of the key 100. In addition, in order to facilitate the pressing element 30 to be lifted and reset automatically during the lifting process, the button 100 may further include a reset elastic element 70, and the reset elastic element 70 may be disposed in the accommodating cavity 10a and elastically abutted between the cavity bottom wall of the accommodating cavity 10a and the pressing element 30. As such, when the pressing member 30 is pressed down, the restoring elastic member 70 may be pressed and compressed, and then the pressing member 30 may be driven to ascend while the restoring elastic member 70 is elastically restored.

It can be understood that the pressing member 30 and the elastic return member 70 are disposed in the first cavity 10b, and the elastic sound generating member 50 is disposed in the second cavity 10c, so that the pressing member and the elastic return member are disposed in different cavities to perform their respective operations more stably, thereby reducing the possibility of interference. The lower partition 111 may be provided with a lower through hole 111a, and the upper partition 131 may be provided with an upper through hole 131a, where the upper through hole 131a communicates with the lower through hole 111 a. At this time, the portion of the pressing piece 30 extending into the second cavity 10c may be elevated and lowered in the lower and upper via holes 111a and 131 a. Of course, in other embodiments, only the lower partition 111 may be provided with the lower through hole 111a, and the portion of the pressing member 30 extending into the second cavity 10c may be lifted and lowered in the lower through hole 111 a. Or only the upper partition plate 131 is provided with the upper through hole 131a, and the portion of the pressing member 30 extending into the second cavity 10c may be lifted and lowered in the upper through hole 131 a.

It can be understood that certain limiting effect can be played to the sounding elastic piece 50 through the mounting groove 11a, the possibility that the sounding elastic piece 50 shakes is reduced, and therefore stable installation of the sounding elastic piece 50 at a preset installation position is facilitated. Meanwhile, the arrangement may also be such that the installation of the sounding elastic member 50 is facilitated.

The second pressing plate 133 can be connected to both the upper cover 13 and the upper partition 131 to improve the connection strength of the upper partition 131 and ensure the abutting and limiting effect on the spiral section 51 of the sounding elastic member 50.

It can be understood that the pressing member 30 is protruded to pass through the lower through hole 111a of the lower partition 111 and the upper through hole 131a of the upper partition 131 to extend into the second cavity 10c to drive the torque arm section 53, so that the structure of the pressing member 30 is simple, and the structure of the pressing member 30 is simplified. Of course, in other embodiments, the side wall surface of the pressing element 30 is connected to an L-shaped abutting rod, and the lower end of the L-shaped abutting rod abuts to drive the torsion arm section 53 to rotate.
