Fig. 2 is the first embodiment of the button structure of the present utility model. Please refer to FIG. 2 and FIG. 3 at the same time. The button structure 20 of the present invention includes a keycap 201 , an engaging member 202 , an elastic member 203 , a protruding portion 204 and a supporting member 206 . Each component is described as follows:

The keycap 201 has a bottom surface. The engaging member 202 is disposed on the bottom surface and encloses a space 202a. In addition, the engaging member 202 is in the shape of a square frame with a notch 202b, and an opening 202c is disposed at the bottom.

The elastic member 203 is located below the keycap 201 and disposed above a substrate 205 . The material of the elastic member 203 can be rubber, and the shape of the elastic member 203 can be a cylinder.

The protruding part 204 is (for example) an iron sheet, which is glued on the top of the elastic member 203. The width d1 of the protruding part 204 is smaller than the width d2 of the inner space 202a of the engaging member, and the width d1 of the protruding part 204 is roughly equal to that of the card. The width d4 of the notch 202b of the engaging member, so that the protruding part 204 can be fitted in the space 202a of the engaging member 202 in a movable (sliding) manner parallel to the cap key 201, and the elastic member 203 can pass through the engaging member. The bottom opening 202c is connected to the substrate 205 . Furthermore, the width d1 of the protruding portion 204 is larger than the width d3 of the bottom opening 202 c of the engaging member, so as to prevent the protruding portion 204 from being separated from the engaging member 202 .

The supporting member 206 is disposed between the cap key 201 and the base plate 205 and is pivotally connected with the cap key 201 and the base plate 205 so that the cap key 201 can move up and down relative to the base plate 205 .

Fig. 4 is the second embodiment of the button structure of the present invention. Please refer to FIG. 4 and FIG. 5 at the same time. The button structure 40 of the present invention includes a keycap 401 , an engaging member 402 , an elastic member 403 , a protruding portion 404 and a supporting member 406 . Each component is described as follows:

The keycap 401 has a bottom surface. The engaging member 402 is disposed on the bottom surface and encloses a space 402a. In addition, the engaging member 402 is shaped as an annular frame with a notch 402b, and an opening 402c is disposed at the bottom.

The elastic member 403 is located below the keycap 401 and disposed above a substrate 405 . The material of the elastic member 403 can be rubber, and the shape of the elastic member 403 can be a cylinder.

The protruding part 404 is (for example) an iron sheet, which is glued on the top of the elastic member 403. The width d1 of the protruding part 404 is smaller than the width d2 of the internal space 402a of the engaging member, and the width d1 of the protruding part 404 is roughly equal to that of the card. The width d4 of the notch 402b of the engaging member makes the protrusion 404 fit in the space 402a of the engaging member 402 in a movable (sliding) manner parallel to the cap key 401, and the elastic member 403 can pass through the engaging member. The bottom opening 402c is connected to the substrate 405 . Furthermore, the width d1 of the protruding portion 404 is larger than the width d3 of the bottom opening 402 c of the engaging member, so as to prevent the protruding portion 404 from being separated from the engaging member 402 .

The supporting member 406 is disposed between the cap key 401 and the base plate 405 , and is pivotally connected with the cap key 401 and the base plate 405 at the same time, so that the cap key 401 can move up and down relative to the base plate 405 .

From the above, it can be seen that the existing key structure is based on the connecting part of the keycap and the groove of the elastic member as the main axis of connection, and adopts a tight fit assembly method to connect the two to each other, and then utilizes the pivot connection of the supporting member. To complete a series of components.

The button structure of the present utility model adopts the protruding part of the engaging member and the elastic member as the main connection means, utilizes the notch chute design of the engaging member, and cooperates with the condition that the width of the protruding part is smaller than the width of the engaging member, so that the elastic member The protruding part of the keycap can be moved (slidably) parallel to the keycap, and fits in the space surrounded by the engaging member, so as to achieve the main purpose of connecting the keycap and the elastic member.

Among them, the notch design of the engaging member can ensure a more stable connection between the protruding part of the elastic member and the cap key, completely eliminating the tight fit assembly method used in the prior art, and not only avoiding the key cap due to the connection The eccentric phenomenon of the connection part caused by the inability to align the groove of the part and the elastic member can completely improve the result that the key cap is easy to wear and fall off, resulting in a reduced service life of the key and an increase in the damage rate, and greatly improves the service life of the key.

Therefore, the button structure of the present utility model can not only replace the connecting part of the keycap and the groove of the elastic member in the prior art with the engaging member and the protruding part, but also replace the difficult alignment with the easy-to-assemble chute. The tight fit assembly method greatly reduces the damage rate caused by the assembly process, saves assembly procedures and time, and improves assembly efficiency.

In addition, it can also solve the serious problem that its keys are easy to fall off, so as to improve its service life, which can be called a technology that kills multiple birds with one stone.

Therefore, the overall assembly difficulty of the button member of the present invention can be greatly reduced, and the production and assembly procedures can also completely save time and improve efficiency. The main purpose of the utility model.
