In the description of the present utility model, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0025] The present utility model provides a highly wear-resistant cover plate with self-luminescence at night, which includes a cover plate body. A self-luminous layer surrounding the visible area is provided on the lower surface of the cover plate body in the non-visible area. An anti-scratch layer is provided below the self-luminous layer. A base layer, an anti-scratch layer, and a corrosion-resistant layer are sequentially stacked on the upper surface of the cover plate body from bottom to top.

The thickness of the base layer is 50nm - 100nm. The thickness of the anti-scratch layer is 200nm - 300nm. The thickness of the corrosion-resistant layer is 50nm - 70nm.

[0026] Since the lower surface of the cover plate body is provided with a self-luminous layer, and the self-luminous layer is a phosphor layer, the phosphor layer has good luminous performance and can be used for identification and luminous decoration in night or low-light environments, making it have a cool and beautiful appearance while meeting the requirements of the hardness, wear resistance, thermal stability and chemical stability of the cover plate to attract consumers.

[0027] To enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings. The following describes the present utility model in detail with reference to the drawings and embodiments. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model and should not be construed as a limitation to the present utility model.

[0028] Please refer to Figure 1 , a highly wear-resistant cover plate with self-luminescence at night provided by the present utility model, which includes a cover plate body 1. A self-luminous layer 2 surrounding the visible area is provided on the lower surface of the cover plate body 1 in the non-visible area. An anti-scratch layer 3 is provided below the self-luminous layer 2. A base layer 4, an anti-scratch layer 5 and a corrosion-resistant layer 6 are sequentially stacked on the upper surface of the cover plate body 1 from bottom to top. The self-luminous layer 2 is a phosphor layer. The thickness of the self-luminous layer 2 is 50μm - 80μm, the thickness of the anti-scratch layer 3 is 8μm - 11μm, the thickness of the base layer 4 is 50nm - 100nm, the thickness of the anti-scratch layer 5 is 200nm - 300nm, and the thickness of the corrosion-resistant layer 6 is 50nm - 70nm. Since the lower surface of the cover plate body 1 is provided with a self-luminous layer 2, and the self-luminous layer 2 is a phosphor layer, the phosphor layer has good luminous performance and can be used for identification and luminous decoration in night or low-light environments, making it have a cool and beautiful appearance while meeting the requirements of the hardness, wear resistance, thermal stability and chemical stability of the cover plate to attract consumers.

[0029] Furthermore, the anti-scratch layer 3 is a black anti-scratch ink, and the anti-scratch ink is an anti-scratch ink layer containing talcum powder and phenolic resin. This anti-scratch ink layer can effectively prevent the back surface of the cover plate body 1 from being scratched or worn.

[0030] Furthermore, the base layer 4 is a TiN layer, which is closely attached to the cover plate body 1, and its main function is to enhance the adhesion between the coating and the cover plate body 1.

[0031] Furthermore, the anti-scratch layer 5 is a SiC layer. The SiC layer has extremely high hardness, wear resistance and thermal stability, and can effectively resist scratches, wear and high-temperature corrosion.

[0032] Furthermore, the corrosion-resistant layer 6 is Si3 N 4 layer, Si 3 N 4 The N layer serves as the outermost layer, which not only has excellent hardness and wear resistance, but also has good chemical stability and insulation performance, capable of preventing the cover plate from being eroded by chemical substances and improving the insulation performance.

[0033] Please refer to Figure 2 , as a further optimized solution of Embodiment 1, in this embodiment, a frame-shaped glue overflow groove 7 is etched on the lower surface of the cover plate body 1 located in the non-visible area. Since the glue overflow groove 7 is provided on the lower surface of the cover plate body 1, when the OCA optical adhesive 8 is coated, the OCA optical adhesive 8 will overflow outward under pressure, and the excess glue will flow into and be stored in the glue overflow groove 7, preventing it from continuing to spread outward, thereby restricting the range of outward glue overflow, and it can effectively avoid light leakage caused by the overflow of the OCA optical adhesive 8.

[0034] Furthermore, the OCA optical adhesive 8 is provided on the lower surface of the cover plate body 1, and the OCA optical adhesive 8 is arranged within the area formed by the glue overflow groove 7. The shape of the glue overflow groove 7 can facilitate the shape design of the etching, and the cross-section is not limited to a semicircle, a V shape, etc. Currently, the general thickness of the cover plate body 1 in the industry is about 0.8 mm, and the thickness of the OCA optical adhesive 8 is about 0.1 mm. The etching depth of the glue overflow groove 7 can be designed as 0.05 mm and adjusted in combination with the actual amount of overflow glue.
