In addition, the technical solutions in the embodiments may be combined with each other, but it must be based on the realization of those skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should not be considered to exist, and is not within the protection scope of the present invention.

As shown in fig. 1 and 2, in one embodiment, the electronic device includes a circuit board 100, a base plate 200, a key cap 300, and at least one elastic restoring member 400. The chassis 200 is connected with the circuit board 100. The key cap 300 is movably installed above the base plate 200. The elastic restoring member 400 is disposed between the base plate 200 and the key cap 300. The key cap 300 can be displaced relative to the base plate 200 by an external force. At least one trigger switch 110 is mounted on the circuit board 100; the base plate 200 is provided with through holes 210 corresponding to the number of the trigger switches 110. The trigger switch 110 can extend out of the upper surface of the base plate 200 through the through-hole 210. The elastic restoring member 400 includes a connecting portion 410 and an elastic portion 420 mounted on an end of the connecting portion 410. One end of the connecting portion 410 is connected to the bottom plate 200, and the other end mounted with the elastic portion 420 is tilted toward a direction away from the bottom plate 200. When no external force is applied, the elastic part 420 abuts against the key cap 300. When external force acts on the elastic reset piece 400, the keycap 300 can elastically deform the elastic reset piece, and the trigger switch can be pressed. After the external force disappears, the key cap 300 can be reset under the restoring force of the elastic reset piece 400.

Specifically, when the key cap 300 is pressed to move toward the circuit board 100, the connection portion 410 provides a first portion of the damping force for the key cap 300 by deforming, and when the connection portion 410 is pressed to be flat, the elastic portion 420 continues to deform to provide a second portion of the damping force for the key cap 300. Through the buffering effect of the two parts of the elastic reset piece 400, the keycap 300 keeps stable in the moving process, and the use of the switch key 10 is ensured. When the key cap 300 touches the trigger switch 110 of the circuit board 100, the elastic part 420 and the connecting part 410 of the elastic reset piece 400 can provide sufficient resilience for the key cap 300. Therefore, the elastic reset piece 400 can well replace a spring structure, effectively solves the problem that the spring in the existing switch key 10 is short in service life, and is simple in structure and convenient to use.

As shown in fig. 3 and 4, in an embodiment, the bottom plate 200 is provided with an abdicating groove 220 corresponding to the position of the elastic reset piece 400, so that the key cap 300 has a sufficient moving distance to be able to contact with the trigger switch 110.

As shown in fig. 5, in an embodiment, a pressing portion 310 for pressing the trigger switch 110 is convexly disposed on the key cap 300, so as to be in contact with the trigger switch 110, and ensure the use effect of the key cap 300.

As shown in fig. 4 and 5, in one embodiment, the key cap 300 is snap-fit to the base 200. The key cap 300 further has a locking portion 320, the bottom plate 200 defines a locking groove 230, and the locking portion 320 is locked to the locking groove 230. Due to the arrangement, the keycap 300 cannot be easily separated from the base plate 200 under the action of the elastic reset piece 400, so that the keycap cannot be normally used.

As shown in fig. 3 and 5, in an embodiment, a surrounding edge 330 is further protruded from a position of the key cap 300 near the edge, the bottom plate 200 is provided with a mounting groove 230, and the surrounding edge 330 is fittingly mounted in the mounting groove 230. The surrounding edge 330 is provided to prevent dust or water mist from entering the inside of the circuit board 100, thereby protecting the circuit board 100 from being used safely.

As shown in fig. 3 and 4, in an embodiment, the elastic portion 420 includes two abutting portions 421, and the two abutting portions 421 form an included angle, so as to ensure the contact effect between the elastic portion 420 and the key cap 300, thereby ensuring the normal use of the elastic reset piece 400.

As shown in fig. 3, in one embodiment, at least two elastic restoring members 400 are disposed at opposite sides of each through hole 210. So set up, not only can make key cap 300 atress balanced like this, can not toward one side slope, it is stable to use, and the atress that resets moreover is bigger, and the result of use is better.

As shown in fig. 6, in an embodiment, the present invention further provides a switch panel 20, where the switch panel 20 includes a base 21, a display 22 and a switch key 10, and the specific structure of the switch key 10 refers to the above embodiments, and since the switch panel 20 adopts all technical solutions of all the above embodiments, all beneficial effects brought by the technical solutions of the above embodiments are at least achieved, which is not repeated herein. The display screen 22 and the switch keys 10 are arranged on the base 21.

The technical features of the embodiments described above can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
