[0033] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.
[0034] In a first aspect of the present disclosure, there is provided an electronic device decoration component, referring to Figure 1 As shown, the decoration component includes a decoration substrate 10, a texture layer 20, an ink layer 30 and a transparent cover plate 40 which are stacked in sequence. The texture layer 20 has closely arranged texture structure units 21, and the texture structure units 21 are conical protrusions facing the ink layer 30.
[0035] According to the embodiment of the present disclosure, the conical protrusion may be a square conical protrusion or a circular conical protrusion, and the texture structure unit 21 facing the ink layer 30 means that the tip of the conical protrusion faces the ink layer 30. In one embodiment, the texture structure unit 21 is a square conical protrusion (i.e., a pyramid type), so that the texture layer 20 has the following structure: Figure 2In this way, under the illumination of the light source, the conical surface of the texture structure unit can reflect the light to different degrees, presenting a three-dimensional flickering effect. Furthermore, when the external light source changes, the light reflection effect of the texture structure unit can also change accordingly. For example, the reflected light is stronger under high light, thus presenting a bright and dazzling visual effect, while the reflected light is weaker under low light, presenting a visual effect like starlight at night, bringing users a rich and varied visual experience.
[0036] In the texture layer 20, the number of texture structure units 21 is not limited, and the height and bottom size of the conical protrusion can vary within a certain range. In one embodiment, the height of the conical protrusion can be 20-30 μm, and the bottom diameter can be 130-150 μm. Preferably, the height of the conical protrusion is 22-28 μm, and the bottom diameter is 135-145 μm, so as to further enhance the visual effect of the appearance of the decorative component.
[0037] The texture layer 20 is formed by curing the coating liquid and the adhesive. The types of the coating liquid and the adhesive can be common in the art, and the present disclosure has no special restrictions. For example, the coating liquid can include the following components: 20 to 40% by weight of a diluent, 50 to 70% by weight of polyacrylate, 0.5 to 5% by weight of a photocuring agent, and 0.5 to 5% by weight of an auxiliary agent; the adhesive can be a UV glue, specifically including the following components: 20 to 40% by weight of acrylic acid, 50 to 70% by weight of polyacrylate, 0.5 to 5% by weight of a photocuring agent, and 0.5 to 5% by weight of an auxiliary agent.
[0038] In one embodiment, the ink layer 30 is formed on the surface of the transparent cover plate 40, and the transmittance of the transparent cover plate 40 is 10-35%, the haze is 0.04-0.08%, and the particle size is 8-10μm. The transmittance, haze and particle size of the transparent cover plate 40 are all detected by testing methods and equipment well known in the art. For example, the transmittance can be tested by a spectrophotometer, the haze can be tested by a light haze meter, and the particle size can be tested by a surface roughness meter. In this embodiment, the transparent cover plate 40 formed with the ink layer 30 has a lower haze and a finer raw material particle size, which is conducive to presenting a pure sense of light transmission and further enhancing the appearance visual effect of the texture layer 20. Furthermore, the material of the ink layer can be infrared-transmitting ink (IR ink).
[0039] According to the embodiment of the present disclosure, the material of the decorative substrate 10 can be a common electronic equipment substrate plate, such as PC / composite plate, etc. The material of the transparent cover plate 40 can be a glass lens, sapphire, etc.
[0040] Further, in one embodiment, the decorative substrate 10 and the transparent cover 40 may have an inner surface and an outer surface respectively, and the inner surface of the decorative substrate 10 faces the inner surface of the transparent cover 40. The texture layer 20 may be formed on the inner surface of the decorative substrate 10, and the ink layer 30 may be formed on the inner surface of the transparent cover 40. There is a gap 60 between the texture layer 20 and the ink layer 30, and the distance of the gap 60 can be designed as needed. In one embodiment, the gap distance between the texture layer 20 and the ink layer 30 may be 0.1 to 2 mm, and in one embodiment, 0.5 to 0.8 mm. In this way, the visual effect presented by the decorative component can be made more spatial and three-dimensional, and the overall visual effect level is enriched.
[0041] Furthermore, in one embodiment, the decoration component may further include a fixing member 50, and the fixing member 50 is used to fix the decoration substrate 10 and the transparent cover plate 40. In one embodiment, the fixing member 50 has a first mounting groove and a second mounting groove relative to each other, and the decoration substrate 10 and the transparent cover plate 40 are fixed between the first mounting groove and the second mounting groove, respectively. There is no special restriction on the material of the fixing member 50, for example, it can be metal, composite plate, injection-molded PC, etc.
[0042] According to the embodiment of the present disclosure, the decorative component can be applied to electronic devices with visual appearance requirements, such as mobile phone battery covers, camera decorative parts, and tablet computers. In one embodiment, the decorative component can be a camera decorative component.
