Problems solved by technology

However, in the existing luminous keys, the point light source is usually placed under the transparent or translucent key, and the light emitted by the light source is directly transmitted through the key. The surface of the button receives uneven light, resulting in uneven brightness of the light passing through the button, which affects its visual effect

Abstract

The present invention relates to a button structure and an electronic device using the button structure. The button structure includes a circuit board, a switch module, a light-emitting component and a button body. The switch module, the light-emitting component and the button body are arranged on the circuit board. The button body includes a light guide and a pressing member. The pressing member is installed on the light guide and aligned with the switch module. Pressing the pressing member can trigger the switch module to control the light-emitting component to emit light. The light guide includes The bottom wall and the peripheral wall surrounding the bottom wall, the peripheral wall and the bottom wall form at least one accommodating cavity, the pressing member is accommodated in the accommodating cavity, the peripheral wall has an annular top, and has a The light guide surface corresponding to the component, the light emitted by the light-emitting component enters the light guide part through the light guide surface, and then emits from the ring-shaped top of the surrounding wall.

Description

technical field [0001] The invention relates to a key structure and an electronic device using the key structure, in particular to a luminous key structure and an electronic device using the key structure. Background technique [0002] In addition to existing input devices such as keyboards and touch panels, electronic devices such as mobile phones are usually equipped with buttons that can control the power switch, volume, unlocking, camera, etc. of the electronic device. At the same time, the electronic device also uses luminous buttons to increase its functionality and interest. However, in the existing luminous keys, the point light source is usually placed under the transparent or translucent key, and the light emitted by the light source is directly transmitted through the key. The surface of the button receives uneven light, resulting in uneven brightness of the light passing through the button, which affects its visual effect. Contents of the invention [0003] I...
