[0022] The present invention will be further described in detail below in conjunction with the embodiments.

[0023] Example 1

[0024] refer to Figure 1 to Figure 5 The utility model provides a silent keyboard switch, comprising an upper cover 1, a handle 2, a base 3 and a spring 4. The upper cover 1 is arranged on the base 3 and forms a receiving space with the base 3.

[0025] The base 3 is provided with a fixing column 31, a hollow hole 32 and a first receiving groove 33. The first receiving groove 33 is provided with an upper groove body 331, an inclined surface 332 and a lower groove body 333 which are integrally connected. The outer width of the lower groove body 333 is greater than the outer width of the upper groove body 331. There are two first receiving grooves 33, which are symmetrical and located on both sides of the fixing column 31. The hollow hole 32 is located in the fixing column 31, and its position corresponds to the position of the limiting rod 23.

[0026] The upper cover 1 is provided with two card slots 11, and the top ends of the two card slots are provided with a cover 12. The two card slots 11 are symmetrical, and their positions correspond to the two first receiving slots 33 one by one.

[0027] The handle 2 includes an integrally connected handle body 21, two clamping parts 22, a limiting rod 23 and two buffer groups 24. The two clamping parts 22 are symmetrical and are respectively located on two sides of the handle body 21. The limiting rod 23 is located below the handle body 21 and inserted into the hollow hole 32.

[0028] The clamping portion 22 includes a first main body plate 221, a second main body plate 222 and a fixing plate 223. A rectangular notch 211 is provided on the side of the handle body 21, and the first main body plate 221 and the second main body plate 222 are integrally connected vertically to both sides of the notch 211. The fixing plate 223 is located between the first main body plate 221 and the second main body plate 222, and is integrally connected to the first main body plate 221 and the second main body plate 222. The height of the fixing plate 223 is shorter than the height of the first main body plate 221 and the second main body plate 222.

[0029] The buffer group 24 includes an upper buffer member 241 and a lower buffer member 242. The upper buffer member 241 and the lower buffer member 242 are both located between the first main body plate 221 and the second main body plate 222. The upper buffer member is located above the fixed plate 223, and its bottom end is integrally connected to the top surface of the fixed plate 223. The lower buffer member 242 is located below the fixed plate 223, and its top end is integrally connected to the bottom surface of the fixed plate 223. The top end of the upper buffer member 241 is higher than the top ends of the first main body plate 221 and the second main body plate 222, and the bottom end of the lower buffer member 242 is lower than the bottom ends of the first main body plate 221 and the second main body plate 222. The upper buffer member 241 and the lower buffer member 242 have the same shape, both of which are arc-shaped structures. In the present embodiment, the arc-shaped structure is specifically S-shaped.

[0030] The two buffer groups 24 are connected to the two clamping parts 22 in a one-to-one correspondence, and the positions of the two clamping parts 22 correspond to the positions of the two first receiving grooves 33 in a one-to-one correspondence. During assembly, the upper half of the handle body 21 extends out of the upper cover 1, and the two clamping parts 22, the two buffer groups 24 and the limiting rod 23 are all located in the receiving space. The limiting rod is inserted into the hollow hole of the base, and one end of the spring 4 is sleeved on the outside of the fixing column 31, and the other end is sleeved on the outside of the limiting rod 23. The two clamping parts 22 and the two buffer groups 24 are located in the two first receiving grooves 33 in a one-to-one correspondence, and the upper buffer member 241 is located below the cover 12. When the upper cover 1 and the base 3 are assembled, the two first receiving grooves 33 are clamped in the two clamping grooves 11 in a one-to-one correspondence. When the handle 2 moves up and down, the clamping part 22 moves up and down along the first receiving groove 33, and the upper buffer 241 moves upward to touch the cover 12. The upper buffer 241 buffers and dissipates the force of the handle moving upward, reducing the sound generated by the collision between the clamping part 22 and the cover 12, thereby achieving a mute effect. Similarly, the lower buffer 242 reduces the sound generated by the collision between the clamping part 22 and the bottom of the base 1, thereby achieving a mute effect.

[0031] Example 2

[0032] refer to Figure 2-3 , Figure 6-7 The present embodiment provides a silent keyboard switch, including an upper cover 1, a handle 2, a base 3 and a spring 4. In the present embodiment, the upper buffer 241 and the lower buffer 242 are both in the shape of an arc structure, and the arc structure is specifically hook-shaped, and the structure and connection method of the remaining parts are the same as those of the first embodiment.

[0033] When the present embodiment is in use, the push handle 2 moves downward, and the lower buffer member 242 moves downward along the first accommodating groove 33 with the push handle 2, and the lower buffer member 242 touches the bottom of the base 1, thereby reducing the impact between the clamping portion 22 and the bottom of the base 1 to achieve a silent effect; the spring 4 rebounds and drives the push handle 2 to move upward, and the upper buffer member 241 moves upward along the first accommodating groove 33 with the push handle 2, and the upper buffer member 241 touches the cover 12, thereby reducing the impact between the clamping portion 22 and the cover 12 to achieve a silent effect.

[0034] The above are only some embodiments of the present invention. For ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
