It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be discussed further in subsequent figures.

As shown in fig. 1 to 4, an embodiment of the present application provides a key protection device, which can be applied to electronic devices such as a mobile phone, a computer, a tablet computer, and a smart watch, and can realize function adjustment of the electronic devices, and can effectively prevent the key cap 3 of the electronic device from being impacted and excessively pressing the key body, so as to better protect physical keys of the electronic device.

Specifically, the key protection device includes a case 1, a key main body 2, a key cap 3, and a buffer member 4. Wherein, casing 1 can be electronic equipment's shell, and button cap 3 cooperatees with button main part 2, through pressing button cap 3 in order to press button main part 2 in order to realize the function regulation to electronic equipment. The key body 2 may also be provided with a circuit structure, which is not described herein again.

Further specifically, a mounting hole is provided on the housing 1, and the mounting hole is used for mounting the key cap 3. The key body 2 is arranged inside the shell 1 and can be pressed and triggered by the key cap 3, so that the function of the electronic equipment can be adjusted through the key protection device. The key cap 3 is located inside the casing 1, and part of the key cap 3 extends out of the casing 1 through the mounting hole, so that a user can press the key cap when adjusting functions of the electronic device. Buffering subassembly 4 sets up between button cap 3 and button main part 2, and buffering subassembly 4 receives to press down of button cap 3 can produce deformation and with casing 1 butt.

It should be noted that the buffer component 4 can press the key main body 2 and move a preset distance under the action of the key cap 3, so as to realize the press trigger of the key main body 2. Wherein the preset distance refers to the pressing stroke of the key cap 3.

In the prior art, when the distance is preset, the key cap 3 normally presses and triggers the key main body 2; when the pressing stroke of the key cap 3 is greater than the preset distance, the key body 2 is pressed excessively. In the present application, when the key cap 3 moves a predetermined distance, the buffer component 4 will deform and abut against the housing 1. Receive casing 1's restriction, buffering subassembly 4 will no longer take place deformation, promptly, restrict the stroke of pressing according to key cap 3 to better protected button main part 2, prevent effectively that the excessive of key cap 3 to button main part 2 from pressing when taking place the striking, can better protect button main part 2, thereby improve this button protection device's life.

The key protection device provided by the embodiment of the application has the advantages that the structural design is reasonable, the key main body 2 can be well protected, and the key main body 2 is effectively prevented from being excessively pressed by the key cap 3. Wherein, through the buffering subassembly 4 that sets up between key cap 3 and button main part 2, it can produce deformation and with 1 butt of casing when receiving pressing according to key cap 3 to carry on spacingly to key cap 3, thereby avoid further pressing button main part 2 according to key cap 3.

Alternatively, the buffer assembly 4 includes an elastic member 41 having an arc shape, the elastic member 41 protrudes toward the key cap 3, and the elastic member 41 can be deformed and moved toward the key main body 2 by being pressed by the key cap 3.

In the above embodiment, the elastic member 41 protruding toward the key cap 3 can not only press the key main body 2 under the pressing action of the key cap 3, so as to realize the pressing trigger of the key main body 2, but also increase the length of the elastic member 41 after deformation in the pressing process, so as to be able to abut against the housing 1 well, and further, to restrict the excessive movement of the key cap 3.

Even if the key cap 3 is impacted, the pressing stroke of the key cap 3 is limited by the elastic member 41, so that the key body 2 is not pressed excessively, and the key body 2 can be protected well.

Optionally, the cushion assembly 4 further comprises a compression member 42;

the two ends of the elastic member 41 are respectively provided with a compression member 42, and one end of the compression member 42 away from the elastic member 41 is fixed to the housing 1.

In the above embodiment, the compression member 42 can apply an acting force to the elastic member 41, and the elastic member 41 is simultaneously limited by the key cap 3, so that a relatively stable state can be maintained, and after the pressing operation of the key cap 3 is finished, the compression member 42 can realize the reset of the elastic member 41, so that the elastic member 41 can be ensured to better protect the key body 2 when the key cap 3 is pressed at each time, and the operation is very convenient.

Optionally, the compression member 42 is a spring. When the compression member 42 is a spring, it is not only low in cost, but also easy to assemble, and it also helps to realize the return of the elastic member 41.

Optionally, the buffering assembly 4 further includes a guiding post 43, the guiding post 43 is fixed to the housing 1, and the spring is sleeved on the guiding post 43.

In the above embodiment, the guide posts 43 can better limit the compression direction of the spring, thereby helping to restore the spring and restore the elastic member 41 when the keycap 3 is released.

The term "return of the elastic member 41" means that the shape, length, and position of the elastic member 41 are returned to their original shapes so that the pressing stroke of the key cap 3 is limited when the key cap 3 is pressed next time.

Optionally, the compression member 42 is a foam or a spring. This allows the compression member 42 to be of relatively simple construction, easy to install and relatively low cost.

Optionally, the buffering assembly 4 further includes a fixing member 44, the fixing member 44 is disposed inside the housing 1, the compressing member 42 is fixed on the fixing member 44, and the elastic member 41 is deformed and then forms an abutment with the fixing member 44 through the compressing member 42.
