Key mechanism

Abstract

The invention discloses a key mechanism capable of identifying whether a keycap is replaced or not. The key mechanism comprises a substrate, a keycap, an elastic assembly, an optical detection moduleand a processor. The keycap is arranged on the substrate, and the keycap is provided with a reflection assembly. The elastic assembly is arranged between the substrate and the keycap. The optical detection module is arranged on the substrate and is used for receiving the optical signals reflected by the reflection assembly. The processor is arranged on the substrate and is electrically connected with the optical detection module. The processor is configured to analyze the optical signal to obtain the movement information and the type information of the keycap. A user can replace the reflectionassembly or the keycap with the reflection assembly so as to adjust the operation mode of the key mechanism and change the use hand feeling of the key mechanism. Therefore, the key mechanism providedby the invention can effectively identify the reflection coefficient and the reflection assembly and the key cap thereof so as to determine how to switch and trigger the operation mode of the key mechanism.

Description

technical field [0001] The invention relates to a key mechanism, in particular to a key mechanism capable of identifying whether a keycap is replaced. Background technique [0002] see Image 6 , Image 6 It is a mechanical button 60 in the prior art. The keycap 62 of the conventional mechanical key 60 moves relative to the base plate 64 through the lifting unit 66 . When the keycap 62 is pressed and moves downward relative to the support member 64 , the elastic component 68 is elastically deformed to contact the switch 70 on the substrate 64 to form a conductive path and output an activation signal. The actuation signal is analyzed to obtain control instructions for the pressed mechanical key 60 . However, when the keycap 62 is pressed downwards, the traditional mechanical key 60 uses the cylinder in the keycap 62 to contact the switch 70, and the user can only feel a certain pressing feeling during the operation stroke of the traditional mechanical key, so how to design ...
