AI Technical Summary

Technical Problem

When the key caps of traditional backlit keyboards form character shapes, the UV protective paint layer is easily damaged, resulting in easy wear and tear in the laser engraving, and characters are not easy to maintain durability.

Method used

The character area formed by the radium engraving is filled with transparent protective paint to form an edge sealing layer, providing secondary protection and enhancing the durability of the character area.

Benefits of technology

By filling with transparent protective paint, the spray coating of the character area is more durable, reducing the risk of paint loss or disconnection.

Description

Technical Field

[0001] The utility model relates to a backlit keyboard, in particular to a keycap of a backlit keyboard and a backlit keyboard. Background Art

[0002] During the production process of the keycap of a traditional backlit keyboard, it includes spraying a primer 2 on the keycap body 1 - spraying a topcoat 3 - laser engraving the topcoat to form a character shape 5 - spraying a UV protective paint 4, as Figure 1 shown; however, due to differences in cost, paint color difference, or language characters, it is not easy to set inventory or quickly produce samples, with a long production period and poor adaptability. To solve this problem, the prior art adopts spraying the UV protective paint first and then laser engraving the topcoat, that is, spraying a primer - spraying a topcoat - spraying a UV protective paint - laser engraving the topcoat to form a character shape on the keycap. But in this method, the UV protective paint layer will be damaged when laser engraving the character shape, making the laser engraved area prone to wear. Summary of the Utility Model

[0003] Purpose of the utility model: The purpose of the utility model is to provide a keycap of a backlit keyboard and a backlit keyboard that can make the laser engraved character area more durable and the characters not easy to lose paint or break lines.

[0004] Technical solution: A keycap of a backlit keyboard according to the utility model includes a keycap body, a primer layer, a topcoat layer, and a UV protective paint layer sequentially arranged on the keycap body, and a character area is laser engraved on the topcoat layer and the UV protective paint layer; a sealing edge layer is provided on the character area.

[0005] Preferably, the sealing edge layer is a transparent protective paint filling layer.

[0006] Preferably, the transparent protective paint is a wear-resistant paint.

[0007] Preferably, the transparent protective paint is a UV paint or a PU paint.

[0008] Preferably, the area of the sealing edge layer is larger than the area of the character area.

[0009] Preferably, the area of the sealing edge layer is smaller than the area of the character area.

[0010] Preferably, the keycap is a transparent keycap.

[0011] A backlit keyboard according to the utility model includes the above keycap.

[0012] Advantageous effects: Compared with the prior art, the utility model has the following advantages: After filling the laser engraved character area with a transparent protective paint, a secondary protective wrapping and sealing edge effect is formed, making the spray coating in the character area more durable and the characters not easy to lose paint or break lines. Description of the Drawings

[0013] Figure 1 Schematic diagram of the keycap structure of a traditional keyboard;

[0014] Figure 2 Schematic diagram of the keycap structure of the present utility model. Detailed implementation manners

[0015] The technical solution of the present utility model will be further described below with reference to the accompanying drawings.

[0016] As Figure 2 shown, a keycap of a backlit keyboard disclosed by the present utility model includes a keycap body 1. The keycap body 1 is a transparent keycap. A primer layer 2, a topcoat layer 3 and a UV protection paint layer 4 are sequentially provided on the keycap body 1. A part of the topcoat layer 3 and the UV protection paint layer 4 covering the surface of the keycap body 1 is removed by laser engraving technology to form a character area 5 by laser engraving. After laser engraving, since the UV protection paint layer 4 is damaged, the laser-engraved part is prone to wear. Therefore, a transparent protection paint is filled in the character area 5 by means of spraying or silk-screen printing to form a sealing edge layer 6, so as to achieve the effect of filling the character area and forming a sealing edge. The area of the transparent protection paint filled in the laser-engraved character area is based on the character area, and can be slightly smaller than the character area or slightly larger than the character area. The transparent protection paint is a wear-resistant paint, and can be a UV paint or a PU paint. After the character area of the keycap of the present utility model is filled with the transparent protection paint, a secondary protection sealing and wrapping effect is formed, so that the spray coating in the character area is more durable and the characters are not prone to paint peeling / line breakage. The present utility model also provides a backlit keyboard adopting the keycap of the present utility model.
