Abstract

The invention discloses a button structure, comprising an upper cover, a bottom casing connected to the upper cover, an actuation column which moves up and down relative to the upper cover, a ring-shaped elastic device which is disposed between the bottom casing and the actuation column and boosts the actuation column upwardly, and a trapezoid-similar light guiding column. The bottom housing is provided with a bottom housing inner surface, an arc-shaped vertical sidewall having a sidewall gap, and a bottom opening. The arc-shaped vertical sidewall divides the bottom housing inner surface intoa sidewall surrounding zone and a sidewall non-surrounding zone. A horizontal extending segment of the trapezoid-similar light guiding column is disposed in the bottom opening, and the vertical extending segment of the trapezoid-similar light guiding column is disposed in the arc-shaped vertical sidewall. When the button structure is disposed on a circuit board, the light source of the circuit board aligns with the horizontal extending segment, and the light is led to the top face of the vertical extending segment through the transmission of the trapezoid-similar light guiding column. The invention is advantageous in that the visibility of the button structure in darkness or environment with insufficient illumination can be enhanced; the demand of appearance beauty, visual sense quality orstimulation degree of buttons can be met for users.

Description

technical field [0001] The invention relates to a button structure. Specifically, the present invention relates to a key structure with light guiding function. Background technique [0002] Buttons are an important tool for inputting information and instructions and switching states in various devices including electronic devices, and they have become a common and indispensable necessary equipment for people in the modern information society. Therefore, in addition to the basic functionality, many users also expect to improve the structural design of the buttons, so as to enhance the aesthetic appearance of the buttons, enhance the visual texture of the buttons, or enhance the visual stimulation of the buttons. [0003] On the other hand, when the environment is too dim or the lighting is insufficient, it is often difficult to recognize the keys when using them, and may increase the chance of input errors or impaired vision. In view of the above reasons, it is necessary to...
