[0002] As an indispensable input device for computers, the keyboard is primarily used for inputting text, symbols, or numbers. With the increasing prevalence of computers, users operate them in various environments. However, in low-light conditions, users often struggle to see the keys clearly, making accurate typing difficult. Therefore, keyboard manufacturers have developed backlit keyboards designed for dark environments. These backlit keyboards not only allow users to clearly identify symbols and text in dim lighting but also offer a stylish appearance and a novel user experience, leading to their increasing adoption in laptops and gaming keyboards.

[0003] Regarding the design of the keycap caps, the existing technology has the following technical problems: traditional keycaps are not light-transmitting, making it difficult for users to accurately identify the keycaps in dark environments, thus affecting usability. Furthermore, the characters or patterns printed on traditional keycaps are easily rubbed off or become blurred, causing inconvenience to the user. Therefore, this invention is hereby applied for.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0020] As shown in Figures 1-3, this utility model relates to a light-emitting laptop keyboard cap structure, including a cap base 2 and a top cap body 1 disposed on the cap base. The top surface of the top cap body is inclined at an angle of 10° to 15°. A character groove 10 is recessed in the middle of the top surface of the top cap, and character elements 101 are disposed within the character groove. The character elements are letters, punctuation marks, and numbers. The UV varnish used to fill the character groove is either epoxy resin coating or made of polybutylene terephthalate (PET). Due to the non-spraying design, therefore... The keyboard is designed for longer use. The top cover includes a top plate and side walls around the top plate. The top plate includes a first light-transmitting layer 102 and a second light-transmitting layer 104. A ceramic layer 101 is provided at the corner formed by the top plate and the side plate. The ceramic layer is inlaid and its contact surface is an interlocking surface or a concave-convex surface. A light-emitting layer 9 is provided on the side wall near the ceramic layer. The light-emitting layer can add brightness to the keyboard in a dark environment. The base of the cover is narrow at the top and wide at the bottom. A recessed platform 3 is provided around the top surface of the base. The top cover is placed on the recessed platform.

[0021] As a technical improvement, the top surface of the cap base is provided with a light-transmitting area 5, the size of which is at least opposite to the character piece. The top surface of the cap base is made of a transparent material, generally thermoplastic polyester, preferably polybutylene terephthalate (PBT). The inner cavity of the cap base is provided with an installation cylinder 7 located below the light-transmitting area.

[0022] As a technical improvement, a Fresnel lens 6 is provided on the mounting cylinder 7, with the Fresnel surface of the Fresnel lens located on the top surface.

[0023] like Figure 3 As shown, as a technical improvement, the light-emitting layer is a closed glass ring 91, with a receiving groove 11 on the side wall to accommodate the glass ring. A filling material 92 is provided in the sealed hollow layer inside the glass ring, wherein the filling material is filled with self-luminous tritium gas, fluorescent material, or phosphorescent material. There is also a baffle 93 on the outer wall of the glass ring, which is part of the side wall. The baffle prevents the glass ring from falling off. Due to the presence of the baffle, the receiving groove is wider inside and narrower outside. In the design, the outer surface of the glass ring is flush with the side wall surface of the top cover body.

[0024] As a technological improvement, the first light-transmitting layer is made of transparent glass or translucent ABS material.

[0025] As a technological improvement, the second light-transmitting layer is a polycarbonate sheet or transparent glass.

[0026] As a technological improvement, a light-guiding microstructure 103 is provided on the bottom surface of the second light-transmitting layer. The light-guiding microstructure can scatter light, allowing light to emerge from multiple angles, thus enabling a wider range of light to pass through the second light-transmitting layer from below, thereby achieving the maximum uniform light transmission effect.

[0027] As a technical improvement, a light source 8 is installed inside the mounting cylinder. The light source is located at the focal point of the Fresnel lens, and the Fresnel surface of the Fresnel lens faces away from the light source. According to the characteristics of the lens, a parallel light beam can be generated. After the light source is emitted, it passes through the Fresnel lens through the mounting cylinder and then generates parallel light. After passing through the light guide microstructure, it passes through the second light-transmitting layer and the first light-transmitting layer. Due to the presence of the light guide structure, the light can be dissipated and diffused. Then, it passes through the light-transmitting area and illuminates the characters. At the same time, a light-emitting material is set inside the glass ring, which can also enhance the brightness of the keyboard cover.
