Luminous key, luminous key switch assembly and key structure with removable key cap

Abstract

The invention discloses a luminous key, a luminous key switch assembly and a key structure with a removable key cap, wherein, the luminous key is applied to the luminous key switch assembly and comprises a light guide body and the key cap; the light guide body is combined in the key cap, touches a switching element through a press convex block and receives light from a light source through a light receiving structure so that the light is guided to depart from the top surface of the key cap through a light outgoing structure; and the edge of the key cap stretches to form two connecting pieces, and the connecting pieces are clamped by a clamping element on the internal surface of a shell so as to support the key cap at the key hole of the shell, thus realizing tool-free rapid assembly of the key cap.

Description

technical field [0001] The invention relates to the lighting of keys, in particular to a luminous key structure, a luminous key switch assembly and a key structure with fast detachable key caps. Background technique [0002] Button symbols are usually provided on the surface of the button caps for users to quickly identify the functions corresponding to the buttons. However, when operating an electronic device in a place with poor lighting, the user often cannot quickly identify the position of the key and the key mark on the key, and thus cannot operate the key correctly. In order to solve the above problems, various lighting structures are proposed in the prior art to illuminate the keys. [0003] The light source that provides illumination directs the light to the center of the key cap to get the best lighting effect, but for the switch element touched by the key cap, the position of the switch element must also correspond to the center of the key cap in order to get a g...

AI Technical Summary

Problems solved by technology

The disadvantage of the welding method is that it is not conducive to re-work (re-work) or replacing the keycap, and welding tools must be available when installing the keycap

If the keycaps are found to be damaged or of poor quality outside the factory, often the keycaps cannot be replaced individually, but the entire housing must be replaced

The key cap is often the most easily damaged or poor quality component, so the method of fixing the key cap by welding increases the cost of subsequent maintenance or quality control
