Problems solved by technology
Since the light guide and the light source are not directly placed under the pressing part, the light emitted by the light source cannot be evenly projected to the pressing part through the light guide, that is, the image projected from the pressing part will have the shadow of the connecting rod. Therefore, how to design a button structure that can transmit light evenly is the direction that the mechanism design industry needs to work on today.

Embodiment Construction
[0026] see figure 1 , figure 1 It is an exploded schematic view of some components of an electronic device 10 with a light-transmitting key structure according to a preferred embodiment of the present invention. The electronic device 10 includes a panel 12 , a switch 14 disposed on a substrate 13 , a light source 16 disposed on the substrate 13 , and a button structure 18 mounted on the panel 12 for triggering the switch 14 . Wherein, the substrate 13 can be a printed circuit board. The button structure 18 includes a pressing portion 20 and an accommodating portion 22, which are connected to one side of the pressing portion 20. An accommodating space 221 and a protruding portion 24 are formed in the accommodating portion 22, which are connected to the side of the accommodating portion 22. One side, and a light guide 26 , one end of which is disposed above the light source 16 and the other end is disposed in the accommodating space 221 . In addition, the light guide 26 may f...

The invention relates to a key structure with light transmission and a relevant electronic device thereof. The key structure with the light transmission comprises a pressing part, an accommodating part, a protruding part and a light guiding piece, wherein the accommodating part is connected to one side of the pressing part, and an accommodating space is formed in the accommodating part; the protruding part is connected to one side of the accommodating part, and is driven to trigger a switch when the pressing part is pressed; and one end of the light guiding piece is arranged above a light source, the other end of the light guiding piece is arranged in the accommodating space, and the light guiding piece is used for guiding light rays emitted by the light source, so that the light rays are projected onto the bottom side of the pressing part. By using the key structure, the light rays emitted by the light source can be guided effectively to be projected onto one side of the pressing part uniformly to form uniform and light-transmitting projection patterns on the other side of the pressing part, so the aesthetic property of the projection patterns of the key structure is improved substantially.
Description
technical field [0001] The invention provides a button structure and its related electronic device, especially a light-transmitting button structure and its related electronic device. Background technique [0002] In order to increase the fun of use and the entertainment effect, a general electronic device is designed with a light-transmitting button structure to display projected images representing different meanings under different operating states. For example, the power button of a notebook computer does not display any color when the computer is not turned on. When the power cord is electrically connected to the socket to supply power to the notebook computer, the power button can be displayed in red, so as to represent the information of "the power is connected but the computer is not turned on"; and when the power cord is electrically connected to the socket and the notebook computer In between and when the computer is turned on, the power button can be displayed in...
