Please refer to FIG. 6 to FIG. 10 together, which are schematic diagrams 1 to 5 of the use states of the buttons of the present application. As shown in the figure, in this embodiment, when the key 1 is not in use (as shown in FIG. 6 ), the key cap 15 is supported by the elastic support member 157 . At the same time, the other end of the elastic member 13 is fixed, and one end abuts against the feedback protrusion 111 and the driving protrusion 151 upward, wherein the middle section of one end of the elastic member 13 abuts against the feedback protrusion 111, and the end of one end abuts against the feedback protrusion 111. The convex portion 151 is driven.

When the user presses the key 1 (as shown in FIG. 7 ), the key cap 15 moves relative to the key structure 11 , that is, the key cap 15 moves downward, the key cap 15 compresses the elastic support 157 , and at the same time, the driving protrusion 151 presses down the elastic member 13 . The end of the elastic member 13 is twisted and compressed, and the elastic member 13 is twisted with the fixed shaft 1195 as the axis. When the driving protrusion 151 moves vertically downward, the distance of the driving protrusion 151 relative to the fixed shaft 1195 will gradually become longer, and when the length of one end of the elastic member 13 does not change, the end of the elastic member 13 abuts against the driving protrusion The portion of the portion 151 will gradually decrease.

When the keycap 15 is completely pressed down (as shown in FIG. 8 ), the driving protrusion 151 cannot press against the end of the elastic member 13 , that is, the end of the elastic member 13 is separated from the driving protrusion 151 , and the torsional elastic force of the elastic member 13 is released, that is, The elastic restoring force (ie, torsional elastic force) of the elastic member 13 causes the elastic member 13 to return to its original state (as shown in FIG. 6 ). In addition, the pressing shaft 153 of the keycap 15 is pressed against the elastic protruding piece 117 , and the elastic protruding piece 117 is deformed and pressed against the corresponding signal transmission point on the circuit unit 115 , thus completing one signal transmission.

As mentioned above, the elastic restoring force urges the elastic member 13 to return from the torsional compression state to the original state, and under the action of the elastic restoring force, one end of the elastic member 13 will directly impact the feedback convex portion 111 (eg. FIG. 9 ), at the same time, one end of the elastic member 13 abuts against the feedback convex portion 111 . When the elastic member 13 and the feedback convex portion 111 collide with each other, on the one hand, a feedback sound will be generated, and on the other hand, a feedback knocking feeling will be generated.

When the button is no longer pressed (as shown in FIG. 10 ), the elastic support 157 releases the compressive elastic force, so that the elastic support 157 pushes up the keycap 15 again, and at the same time, the elastic protrusion 117 in the housing 119 also returns to its original state, and the elastic The protruding piece 117 also pushes up against the pressing shaft 153 , and drives the keycap 15 upward. Although the end portion of the elastic member 13 will block the moving path of the driving protrusion 151, the material of the elastic member 13 itself is soft. Furthermore, the surface of the driving protrusion 151 relative to the end of the elastic member 13 is the inclined surface 110. The end of 13 will be guided and moved from the inclined surface 110 of the driving protrusion 151, and the compressive elastic force of the elastic support 157 and the restoring force of the elastic protrusion 117 are sufficient to push the driving protrusion 151 back to its original position (as shown in FIG. 5 ). This button can be used again. In this embodiment, keys with feedback can also be applied to keyboards, and the keyboards with keys with feedback can also be applied to electronic devices.

To sum up, the technical solution according to the present application is improved according to the shortcomings of the prior art. Most of the button feedback methods in the prior art rely on the design of the axis. Most of the feedback strength of the buttons is slightly insufficient. Therefore, the present application provides a key, a keyboard and an electronic device, which include a key structure, an elastic member and a key cap. The key structure includes a shell, the shell has a feedback convex part, and the elastic piece is arranged on the shell of the key structure and contacts the feedback convex part. The key cap is arranged on the shell of the key structure, and the key cap is provided with a driving convex portion, and the driving convex portion is in contact with the elastic member. The keycap moves relative to the shell of the key structure, and after the driving protrusion twists the elastic member, the elastic member is separated from the driving protrusion, and the elastic member generates elastic force to hit the feedback protrusion. Produces a feedback tapping feel. In this way, when the user presses the button, the feedback of the button can help the user to have a better feeling of use. Meanwhile, the cost of the button with feedback is lower than that of the button with the axis.

The above are only embodiments of the present application, and are not intended to limit the present application.
