Light-emitting keyboard and shading structure thereof

Abstract

The invention reveals a light-emitting keyboard and a shading structure thereof. The keyboard comprises a bottom case, a light guide plate, a lightproof part, a shading piece, a reflecting piece, and a structural part. The periphery of the light guide plate is provided with first blow holes, and the first blow holes pass through two opposite surfaces of the light guide plate. The lightproof part covers inner wall surfaces of the first blow holes. The shading piece and the reflecting piece are respectively disposed on two opposite surfaces of the light guide plate, and are closely attached to the lightproof part. The bottom case is disposed below the light guide plate, and the lightproof part is provided with a second blow hole. The structural part passes through the second blow hole to be connected to the bottom case. Therefore, the lightproof part, the shading piece and the reflecting piece can prevent light from escaping from the inner wall surface of the light guide plate and being observed by a user from the exterior of the keyboard.

Description

technical field [0001] The invention relates to a luminous keyboard, in particular to a light-shielding structure for a light guide plate of a luminous keyboard. . Background technique [0002] Generally, light-emitting keyboards use a light guide plate to obtain a more uniform backlight. Generally speaking, although the light guide plate is designed to guide the light inside it from the light-emitting surface, the light may also escape from the edge of the light guide plate and form bright lines on the edge of the light guide plate, which interferes with the backlight rendering effect of the luminous keyboard. In addition, the light guide plate usually occupies a considerable configuration area on the luminous keyboard, so the light guide plate also needs to form a through hole or a hole (for example, located on the periphery of the light guide plate) for fixing parts, such as screws, to pass through to lock the shell of the luminous keyboard. . At this time, no matter t...

AI Technical Summary

Problems solved by technology

[0003] In view of the problems in the prior art, the present invention provides a light-shielding structure for a light-emitting keyboard to effectively shield the light escaping from the edge of the light guide plate, and solve the problem that the size of the conventional reflective sheet and the light-shielding sheet in the hole is not enough to be directly bonded to each other , causing the problem that the light cannot be effectively shielded
