[0047] It should be noted that: similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0048] Embodiment one

[0049] Please refer to Figures 1-6 A film-coated cover plate, comprising a glass cover plate 1, the glass cover plate 1 has a non-visible area 11 at the edge of the glass cover plate 1, the non-visible area 11 extends upwardly to have an upper boss 12, the upper boss 12 surrounds the edge of the glass cover plate 1 to form a film-coating cavity 13, and a film-coated protective layer 2 is film-coated in the film-coating cavity 13, wherein the film-coated protective layer 2 comprises a titanium nitride film-coated layer 21 and a silicon carbide film-coated layer 22, the titanium nitride film-coated layer 21 is arranged above the silicon carbide film-coated layer 22.

[0050] The film-coated protective layer 2 further comprises a chromium-nickel alloy film-coated layer 23, and the chromium-nickel alloy film-coated layer 23 is directly film-coated on the surface of the glass cover plate 1.

[0051] The titanium nitride film-coated layer 21, the silicon carbide film-coated layer 22 and the chromium-nickel alloy film-coated layer 23 are sequentially film-coated from top to bottom to jointly form the film-coated protective layer 2.

[0052] The embodiment is to perform chromium-nickel alloy plating film layer 23 plating on the surface of the conventional glass cover plate 1 first. Chromium-nickel alloy has good corrosion resistance and decoration, which can improve the appearance and durability of the glass cover plate 1. In addition, it can also provide certain mechanical strength and enhance the overall performance of the glass.

[0053] Titanium nitride plating film layer 21 and silicon carbide plating film layer 22 are plated on the surface of the chromium-nickel alloy plating film layer 23. Titanium nitride has high hardness, high wear resistance and good chemical stability, which can effectively protect the surface of the glass cover plate 1 from scratching and corrosion. At the same time, the design of the silicon carbide plating film layer 22 below it also has very high hardness and wear resistance, which can further enhance the scratch resistance of the glass cover plate 1 and meet the application in different scenes.

[0054] Embodiment two

[0055] The plating film cover plate provided in embodiment one is further optimized. As shown in Figure 4 the thickness of the plating film protection layer 2 is equal to the depth of the plating film cavity 13;

[0056] Since the upper boss 12 is extended at the edge of the glass cover plate 1 in this embodiment, the edge of the plating film protection layer 2 after plating will be blocked by the outer upper boss 12, avoiding direct exposure to the outside. This ensures the plating effect of the plating film protection layer 2 after plating, making it not easy to fall off. At the same time, the edge can also be protected from bumps, improving the service life of the plating film protection layer 2. This further ensures the performance improvement effect of the plating film protection layer 2 on the glass cover plate 1;

[0057] As a further optimization of this embodiment: the thickness of the titanium nitride plating film layer 21 is between one hundred nanometers and one hundred and twenty nanometers, the thickness of the silicon carbide plating film layer 22 is between nineteen nanometers and twenty-four nanometers, and the thickness of the chromium-nickel alloy plating film layer 23 is between one hundred nanometers and one hundred and twenty nanometers;

[0058] By designing the thickness of the plating film protection layer 2 and the depth of the plating film cavity 13 equally, it is avoided that the plating film protection layer 2 protrudes from the surface of the glass cover plate 1 and causes accelerated wear. At the same time, it is also avoided that the glass cover plate 1 protrudes from the surface of the plating film protection layer 2 and affects the user experience.

[0059] Embodiment three

[0060] The plating film cover plate provided in embodiment one or two is further optimized. As shown in Figure 2 and Figure 6 the corresponding area of the glass cover plate 1 below the plating film cavity 13 is the visible area 14;

[0061] The visible area 14 includes an ink visible area 140 and a display visible area 141, wherein the ink visible area 140 surrounds the display visible area 141 to form the visible area 14.

[0062] The bottom of the glass cover plate 1 is provided with a color-changing ink layer 3 at the position corresponding to the ink visible area 140;

[0063] The visible area 140 of the ink is transparent, so that the thermochromic ink layer 3 can be seen from the outside of the glass cover 1. The thermochromic ink can change color according to changes in ambient temperature, providing intuitive visual feedback and increasing the fun and practicality of the product.

[0064] The display area 141 corresponds to the screen displaying the content below, and is used for displaying the screen.

[0065] Example 4

Figure 3 As shown, a calcium silicate layer 31 and an aluminum silicate layer 32 are arranged sequentially from top to bottom below the inductive color-changing ink layer 3, wherein the thickness of the calcium silicate layer 31 and the aluminum silicate layer 32 is between 30 micrometers and 50 micrometers.

[0067] By designing the calcium silicate layer 31 and the aluminum silicate layer 32, light-sensitive color changing can be achieved through the color-changing ink layer 3, increasing the interactivity and fun of the product. At the same time, the calcium silicate layer 31 and the aluminum silicate layer 32 can also serve as a double protective barrier for the ink layer, not only preventing the ink from being scratched, but also providing heat insulation and protecting the stability of the ink layer in high-temperature environments.

[0068] The bottom of the glass cover plate 1 has a lower protrusion 15 extending downward at the position corresponding to the non-visible area 11. The thickness of the lower protrusion 15 is the same as the thickness of the color-changing ink layer 3, the calcium silicate layer 31 and the aluminum silicate layer 32.

[0069] Meanwhile, the design of the lower boss 15 in this embodiment can also form protection for the color-changing ink layer 3, calcium silicate layer 31 and aluminum silicate layer 32 at the outer edge, and after contacting the frame 4, it can also form support for the glass cover plate 1 as a whole, thus avoiding excessive compression of the color-changing ink layer, calcium silicate layer and aluminum silicate layer.

For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0073] Obviously, the above-described embodiments are only part of the embodiments of the utility model, not all the embodiments, and the preferred embodiments of the utility model are given in the drawings, but do not limit the patent range of the utility model. The utility model can be realized in many different forms, and conversely, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and comprehensive.
