Problems solved by technology
The technology used in the existing luminous keys is mainly to print specific symbols or patterns on the transparent keys, and set a light source at the bottom of the keys to illuminate the corresponding display symbols. However, the printed symbols on the keys are often worn or scratched during use, resulting in Required symbols are not displayed correctly

Embodiment Construction
[0023] Please refer to figure 2 and image 3 , figure 2 is a perspective view of a sculpture according to an embodiment of the present invention, image 3 yes figure 2 Schematic diagram along the H direction. Such as figure 2 As shown, this specific embodiment provides a sculpture 20 , which includes a body 21 and a sculpture part 23 . The body 21 is made of transparent or translucent material, such as glass or acrylic resin, and has a light-incident surface 22 . The engraving part 23 is formed in the body 21. The engraving part 23 can be formed by injection molding, knife engraving or laser etching. The engraving part 21 forms a specific pattern or symbol, such as a power symbol or letter A. When a light beam (not shown) irradiates the engraved portion 23 from the incident surface 22, the engraved portion 23 reflects or refracts the incident light to display the specific pattern or symbol, and the bottom plane 231 of the engraved portion 23 is in contact with the in...

The invention relates to a carving piece, a luminescent key-press component and an electronic device using the same. In the invention, the luminescent key-press component comprises a key-press body and a light source, wherein the key-press body comprises a carving part and a light incident surface, a bottom plane of the carving part is at an angle of 0-90 DEG with the light incident surface, the bottom plane is the plane where the bottom surface of the carving part is positioned, specific patterns or signs are formed on the carving part; and the light source is arranged at one side of the light incident surface, when the key-press body is irradiated by the light source, the incident light of the light source is reflected or refracted by the carving part to ensure that the specific patterns or signs are displayed. The bottom plane of the luminescent key-press component provided by the invention is at an acute angle with the light incident surface, and the entire bottom plane can be irradiated by the incident light emitted by the light source to ensure that the display uniformity of the carving part with the specific patterns or signs is better than that of a traditional design.
Description
technical field [0001] The present invention relates to a carving, a luminous key and an electronic device, in particular to a luminous key component and an electronic device using the luminous key component. Background technique [0002] Engraving specific patterns or characters on transparent glass or plastic, and using light sources to display these specific patterns or characters is a common practice, such as the "Display Computer Engraving Medal" disclosed in Chinese patent CN2302686. The patent discloses as figure 1 As shown, the display computer engraving medal 100 includes a base 10, an engraving piece 12 and a light source 14. The engraving piece 12 has engraving parts 121, 122, and the engraving parts 121, 122 form specific patterns or characters. After one side of 12 enters the light beam 141, the incident light is reflected or refracted by the engraved parts 121, 122 so that people can see specific patterns or characters. Similar designs are also widely used in...
