Abstract
Description
Technical Field
[0001] This utility model relates to the field of decorative cover technology, and in particular to a battery decorative cover. Background Technology
[0002] With the rapid development of the electronics and electric product market, the demand for fiberglass battery decorative covers is constantly increasing, and the market size continues to expand. Consumers' demand for product diversification is constantly increasing. Existing products are mostly produced using spray painting and baking processes, resulting in weak gloss and texture, and a single surface decoration effect. They can only obtain monochrome patterns through simple printing, and the texture is limited to glossy or matte surfaces, making it difficult to support customized designs such as gradients and intricate decorative graphics. Utility Model Content
[0003] The main technical problem solved by this utility model is to provide a solution that can improve gloss and brightness and support the customization of complex decorative patterns.
[0004] To solve the above-mentioned technical problems, the present invention provides a battery decorative cover, comprising: a fiberglass substrate;
[0005] A gray base coat is screen-printed onto the surface of a fiberglass substrate.
[0006] The first color layer is screen-printed on the gray base coat;
[0007] The second color layer is screen-printed on top of the first color layer. The second color layer is used to supplement and enhance the first color layer, thereby increasing the color saturation and pattern complexity.
[0008] Pearlescent ink layer, which is screen-printed onto the second color layer;
[0009] The first UV texture layer is transferred onto the pearlescent ink layer by a UV transfer device, and the first UV texture layer provides a visual texture effect.
[0010] A PVD coating layer covers the surface of the first UV texture layer.
[0011] High-transparency varnish layer, screen-printed onto PVD coating layer;
[0012] The second UV texture layer is transferred onto the high-transmittance varnish layer using a UV transfer device, and provides a tactile texture effect.
[0013] Preferably, a customized pattern is screen-printed on the gray base coat and / or the first color layer and / or the second color layer, the customized pattern including characters, several graphics or gradient effects.
[0014] Preferably, the texture of the first UV texture layer is at least one of brushed texture, CD texture, wood grain, stone texture, diffraction grating or micro-engraving pattern.
[0015] Preferably, the texture of the second UV texture layer is at least one of frosted texture, leather texture, or three-dimensional embossed texture.
[0016] Preferably, the thickness of the gray base coat is 8-10 μm.
[0017] Preferably, the thickness of the first color layer is 6-8 μm.
[0018] Preferably, the thickness of the second color layer is 6-8 μm.
[0019] Preferably, the thickness of the pearlescent ink layer is 6-8 μm.
[0020] Preferably, the thickness of the high-transmittance oil layer is 6-8 μm.
[0021] The beneficial effects of this invention are as follows: Through the composite structure design of the first UV texture layer, the PVD coating layer, and the second UV texture layer, a stacked system of gray base oil layer, dual customized color layer, pearlescent layer, first UV texture layer, high reflective PVD coating layer, high transmittance oil layer, and second UV texture layer is sequentially constructed on the glass fiber substrate. This breaks through the limitations of traditional processes. The PVD coating layer and the pearlescent ink layer work together to form a mirror-like metallic luster and layered light effect. The dual color layer supports more refined gradient patterns, and the dual UV texture layer independently realizes the visual effect of CD texture diffraction light and the anti-fingerprint frosted tactile function, increasing the customization dimension. At the same time, the gray base oil layer completely covers the texture of the glass fiber substrate, and the high transmittance oil layer serves as a medium bridging layer between the PVD coating and the second UV texture layer, significantly improving the adhesion of the tactile functional area.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0032] Example:
[0033] refer to Figure 1 A battery decorative cover includes: a fiberglass substrate 1, where fiberglass itself has high strength, heat resistance, and good insulation, but the surface is uneven, and if there are textures or gaps, the reflectivity is poor;
[0034] Gray base coat 2 is screen-printed onto the surface of the fiberglass substrate 1. Gray base coat 2 is a gray base coat used for light-shielding, filling gaps in the fiberglass surface, and masking the texture of the fiberglass itself, thus providing a smooth, uniform, and opaque base for subsequent coatings. The thickness of gray base coat 2 is 8-10 μm. Customized patterns are screen-printed on gray base coat 2, including characters, several graphics, or gradient effects.
[0035] The first color layer 3 is screen-printed onto the gray base coat layer 2 to form the bottom color layer. The first color layer 3 is a colored ink, and both the color and pattern of the first color layer 3 can be customized to enhance product customization. The thickness of the first color layer 3 is 6-8 μm. Customized patterns, including characters, several graphics, or gradient effects, are screen-printed on the first color layer 3.
[0036] The second color layer 4 is screen-printed on top of the first color layer 3, which is a colored ink. The second color layer 4 supplements and enhances the first color layer 3, increasing color saturation and pattern complexity, making the colors in the first color layer 3 richer and more vibrant. It also increases graphic diversity, allowing different colors or patterns to be overlaid on top of the first color layer 3 to achieve more complex visual effects, such as gradients and fine lines. The color and pattern of the second color layer 4 can be customized as needed, thus improving product customization. The thickness of the second color layer 4 is 6-8 μm. Customized patterns, including characters, several graphics, or gradient effects, are screen-printed on the second color layer 4.
[0037] Pearlescent ink layer 5 is screen-printed onto the second color layer 4, thereby increasing brightness and gloss and providing a special visual effect. The color and effect of pearlescent ink layer 5 are customizable, including pearlescent colors such as silver, gold, and iridescent, as well as particle size / density, affecting the final gloss effect, such as a low-key luxury feel or a high-shine feel. Pearlescent ink layer 5 enhances gloss and brightness locally. The thickness of pearlescent ink layer 5 is 6-8μm.
[0038] refer to Figure 1 The first UV texture layer 6 is transferred onto the pearlescent ink layer 5 by a UV transfer device. The first UV texture layer 6 provides an internal visual texture effect. The texture of the first UV texture layer 6 is at least one of the following: brushed texture, CD texture, wood grain, stone texture, diffraction grating or micro-engraving pattern. Of course, the texture pattern can also be freely designed and customized as needed, and the visual effect is affected by the light refraction or diffuse reflection of the texture.
[0039] The PVD coating layer 7 covers the surface of the first UV texture layer 6. By applying PVD coating to the surface of the first UV texture layer 6, a high-gloss, textured coating medium layer is formed, namely the PVD (Physical Vapor Deposition) coating layer. PVD can deposit very uniform, dense, and highly reflective metals, such as chromium, titanium, stainless steel, or compounds, such as titanium nitride (gold) and titanium carbide (black) films, providing a mirror-like high gloss or specific metallic luster, significantly enhancing the high-end texture and perceived value of the product. The PVD coating layer 7 improves the overall gloss and brightness, and combined with the localized effect of the pearlescent ink layer 5, makes the overall gloss and brightness more refined and the effect better. On the other hand, the PVD coating layer 7 is semi-transparent because the first UV texture layer 6 does not have refractive power. If the refractive index of the first UV texture layer 6 were similar to that of the high-transmittance oil layer 8 and the second UV texture layer 9, the first UV texture layer 6 might not be reproducible. The difference in refractive index of the PVD coating layer 7 ensures that the first UV texture layer 6 can be reproduced.
[0040] refer to Figure 1 A high-transmittance varnish layer 8 is screen-printed onto the PVD coating layer 7. The high-transmittance varnish layer 8 protects the PVD coating layer 7 from scratches or oxidation, ensures that the high gloss and color of the PVD coating layer 7 are fully transmitted without affecting the visual effect, provides a good adhesion surface for the outermost UV transfer layer, and serves as the base for the second UV texture layer 9. The thickness of the high-transmittance varnish layer 8 is 6-8 μm.
[0041] The second UV texture layer 9 is transferred onto the high-transparency varnish layer 8 using a UV transfer printing device. The second UV texture layer 9 provides a tactile texture effect. As the surface layer directly in contact with the user's fingers, the second UV texture layer 9 forms a microstructure through UV transfer, primarily providing a tactile experience such as a fine matte finish, leather feel, raised texture, and fingerprint and scratch-resistant physical properties. The texture of the second UV texture layer 9 is at least one of a matte finish, leather texture, or three-dimensional raised texture. Of course, the texture pattern can also be freely designed and customized as needed. The high-transparency varnish layer 8 also serves to connect the second UV texture layer 9. While the second UV texture layer 9 cannot adhere firmly to the PVD coating layer 7, it can adhere well to the high-transparency varnish layer 8, thus stabilizing the position of the second UV texture layer 9 through the high-transparency varnish layer 8. The composite texture layer of the first UV texture layer 6 and the second UV texture layer 9 creates a three-dimensional visual effect.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
