The button structure and the electronic device according to the embodiments of the present application will be described below with reference to FIGS. 1-9 .

As shown in FIGS. 1-9 , according to a key structure according to some embodiments of the present application, the key structure includes a base 1 , a switch elastic piece 2 and an elastic member 3 .

The base 1 has a receiving groove 10 , the base 1 is provided with a first electrode sheet 11 and a second electrode sheet 12 , and the first electrode sheet 11 and the second electrode sheet 12 are exposed at the bottom of the receiving groove 10 . The switch elastic piece 2 is arranged in the receiving groove 10 . The elastic piece 3 is arranged between the first electrode piece 11 and the switch elastic piece 2 , and the switch elastic piece 2 is electrically connected to the first electrode piece 11 through the elastic piece 3 .

When the elastic member 3 is in the first compressed state, the switch elastic piece 2 is in the first position, and the switch elastic piece 2 is separated from the second electrode piece 12 . When the elastic member 3 is in the second compressed state, the switch elastic piece 2 is in the second position, and the switch elastic piece 2 is in contact with the second electrode piece 12 .

In the embodiment of the present disclosure, as shown in FIG. 3 , when the elastic member 3 is in the first compressed state, the switch elastic piece 2 is in the first position, and the switch elastic piece 2 is separated from the second electrode piece 12, so that the button structure is in the Disconnected state. As shown in FIG. 4 , when the elastic member 3 is in the second compressed state, the switch elastic piece 2 is in the second position, and the switch elastic piece 2 is in contact with the second electrode piece 12 , so that the button structure is in a closed conduction state. The elastic support is formed between the switch elastic piece 2 and the first electrode piece 11 through the elastic member 3, which can form a sufficient pressing stroke for the switch elastic piece 2, avoid the problem of false touch, and can support the switch elastic piece 2 in contact with the external structure, Avoid the problem of key shaking caused by gaps.

The elastic member 3 forms an elastic support between the first electrode piece 11 and the switch elastic piece 2, so that the connection relationship of each component can be adjusted by adjusting the compression amount of the elastic member 3 in the space where the button structure can adapt to different assembly sizes. For example, in the first compressed state, the button structure is in the disconnected state, and the first compressed state of the elastic member 3 forms a support for the switch elastic piece 2 to avoid excessive structural gap between the switch elastic piece 2 and the outside.

The compression amount of the elastic member 3 in the second compressed state is larger than that in the first compressed state. The switch shrapnel 2 can be switched between the first position and the second position. Pressing the button structure can make the switch shrapnel 2 move to the second position, and releasing the button structure can make the switch shrapnel 2 move to the first position by the rebound support of the elastic member 3.

In one embodiment, as shown in FIGS. 3-7 , the side of the elastic member 3 facing the first electrode sheet 11 has a first surface 31, the first surface 31 is in surface contact with the first electrode sheet 11, and the elastic member 3 The side facing the switch elastic piece 2 has a second surface 32 , and the second surface 32 is in surface contact with the switch elastic piece 2 .

In the embodiment of the present application, the elastic member 3 has a first surface 31 and a second surface 32 to form surface contact with the switch elastic piece 2 respectively, thereby increasing the contact area. Increasing the contact area can improve the stability of the electrical connection between the switch elastic piece 2 and the first electrode piece 11 , and avoid the problem of contact failure caused by poor contact or unstable contact. Increasing the contact area can also improve the structural stability of the elastic member 3 supported between the first electrode sheet 11 and the switch elastic piece 2, so that the switch elastic piece 2 remains stable during the movement process, and avoids the switch elastic piece 2 from shifting during the movement process. Thereby, the fluency of using the button structure is improved.

The structure of piece 3 interferes.

For example, the direction of applying force to the button structure deviates from the direction in which the switch elastic piece 2 compresses the elastic member 3 , which easily causes the switch elastic piece 2 to deviate during the moving process. One side of the first surface 31 is smaller, so that the elastic member 3 is tapered as a whole, so as to avoid mutual interference with the elastic member 3 when the switch elastic piece 2 deviates during the movement.

Moreover, when the switch elastic piece 2 moves to the second position, the second contact portion 22 is closer to the bottom of the groove, so as to ensure effective contact between the switch elastic piece 2 and the second electrode piece 12 .

For example, the gap distance between the second contact portion 22 and the second electrode piece 12 in FIG. 3 forms the stroke of the switch elastic piece 2 . Under the support of the elastic member 3, the gap distance forms the stroke of the key structure.

The boss 5 is embedded in the groove structure to form a support between the switch shrapnel 2 and the protective film 4, so as to improve the pressing experience between the protective film 4 and the switch shrapnel 2, and avoid the gap between the protective film 4 and the switch shrapnel 2. It avoids the shaking of the keys caused by the overhead structure. For example, the boss 5 is made of elastic material. The embedding of the boss 5 into the groove structure can save space and increase the structural stability of the boss 5 disposed on the switch spring 2 , preventing the boss 5 from breaking away from the supporting position between the switch spring 2 and the protective film 4 .

For example, a button 8 is provided on the outside of the protective film 4 , and the protective film 4 is moved to the side of the base 1 by pressing the button 8 , thereby driving the boss 5 to press the switch spring 2 to move.

In one embodiment, as shown in Fig. 3 and Fig. 4, the button structure further includes a limiting plate 6, the limiting plate 6 is arranged on the base 1, and part of the switch shrapnel 2 is located in the groove between the limiting plate 6 and the receiving groove 10 between the bottom;

For example, the limiting plate 6 has a limiting portion 61 . Part of the structure of the limiting plate 6 is fixed on the base 1 , for example, a fixing glue 7 is provided between the limiting plate 6 and the base 1 . The other part extends into the receiving groove 10 to form a limiting portion 61 , and the switch elastic piece 2 is limited by the limiting portion 61 .

For example, when the elastic member 3 is in the first compressed state, the switch elastic piece 3 abuts against the limiting portion 61 .

In one embodiment, as shown in FIG. 1, FIG. 8, and FIG. connect. The second electrode piece 12 is an annular piece arranged around the first electrode piece 11 .
