Embodiment Construction

[0078] see figure 1 and figure 2 As shown, it is a light-emitting key 100 disclosed in the first embodiment of the present invention, which includes a light guide 110 and a key cap 120 . The light guide body 110 and the button cap 120 are combined into one body, and receive a light to highlight the local pattern features by emitting light.

[0079] refer to figure 1 and image 3 As shown, the light guide body 110 is made of a light-transmitting material, but not limited to a colorless and transparent material. The material for making the light guide body 110 can be colorless and transparent material mixed with pigments, so that the material of the light guide body 110 can pass through the visible light of a specific color and present a specific color.

[0080] The light guide 110 has a top surface 111 and a bottom surface 112 . A light-emitting structure 113 is formed on the top surface 112 , and the cross-sectional shape of the light-emitting structure 113 can be in the...

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...
