Problems solved by technology

[0004] However, if the interference engagement stress between the plug and the socket is too large, it is easy to cause the side wall of the socket to crack
Conversely, if the interfering engagement stress is too small, the plug will easily come out of the slot; the balance between the two is difficult to determine, which often leads to increased process variation and affects the yield and quality of the mechanical key structure

Embodiment Construction

[0022] The embodiment of this specification provides a key structure, which can improve the problem that the side wall of the slot used to combine the keycap and the key shaft is easily burst by the plug or the plug is easy to fall out of the slot, and improve the process yield of the key structure and quality. In order to make the above-mentioned embodiments and other objectives, features and advantages of this specification more comprehensible, several embodiments are specifically cited below and described in detail as follows in conjunction with the accompanying drawings.

[0023] However, it must be noted that these specific implementation cases and methods are not intended to limit the present invention. The invention can still be implemented with other features, elements, methods and parameters. The proposal of the preferred embodiment is only used to illustrate the technical characteristics of the present invention, and is not intended to limit the patent scope of the ...

Abstract

The invention discloses a key structure. The key structure comprises a bottom plate, a first actuating part and a key cap; the first actuating part is arranged on the bottom plate, is combined with the key cap and is used for enabling the key cap to movably reciprocate perpendicular to the bottom plate in the actuating direction. One of the first actuating part and the key cap is provided with a first slot; and the other one of the first actuating part and the key cap is provided with a first plug. The first plug is arranged in the first slot in a penetrating mode in the direction parallel tothe actuating direction. One of the first slot and the first plug includes at least one first projection that projects outwardly perpendicular to the actuation direction and is conformally engaged with the other of the first slot and the first plug. And on the premise of achieving a good interference clamping effect, the risk of bursting due to overlarge transverse stress when the slot and the plug are combined is effectively reduced.

Description

technical field [0001] The present invention relates to a key structure, and in particular to a key structure with a mechanical pressing feel. Background technique [0002] The input device is often used as a communication medium between the user and the electronic device. A common input device is, for example, a multi-key structure. By pressing different keys, the user can cause the electronic device to generate corresponding actions. Among them, the mechanical button structure has the advantages of good hand feeling, long life and short trigger stroke, and is still widely loved by consumers in the market for many years. [0003] A typical mechanical key structure includes at least a key cap, a key shaft (switch) and a bottom plate. Wherein, the keycap is mounted on the bottom plate in a manner capable of reciprocating up and down through the key shaft. The keycap is restricted by the key shaft, and can reciprocate between a top end (Top end) position and a bottom end (B...
