The applicant has found in research that the overall expressiveness of the appearance of the electronic device can be improved by achieving a texture effect on the battery cover. For example, a texture effect may be formed on the base material of the battery cover by a transfer method. The applicant further researches and discovers that after the texture effect is formed on the base material of the battery cover, a color effect can be formed by further coating and silk-screening printing ink with different colors. However, the applicant has found through experimentation that the battery cover formed in this way is dull in color, not bright enough and not glittery enough.

Based on this, the applicant further studies and proposes the technical scheme of the application, and the battery cover with gorgeous colors can be realized by forming the color texture effect on the base material of the battery cover. Referring to fig. 3, fig. 3 is a schematic view illustrating a stacked structure of a housing 30 according to some embodiments of the present disclosure, in which the housing 30 is illustrated by taking a battery cover 30 as an example. The battery cover 30 may generally include a substrate 31 and a pattern layer 32 stacked together.

Alternatively, the base material 31 may be made of a light-permeable material to form the battery cover 30 with high transmittance and high surface hardness. For example, the substrate 31 may be a Polycarbonate (PC) material, and the transparency may reach 90%. The substrate 31 may also be a polymethyl methacrylate (PMMA) material, which has excellent optical properties and temperature change resistance, and the white light transmittance is as high as 92%. The substrate 31 may also be Polyethylene terephthalate (PET) material, which is a milky white or pale yellow highly crystalline polymer with smooth and glossy surface and 86% transparency. The substrate 31 may be made of other materials such as glass, which are not specifically illustrated here.

Further, the substrate 31 includes a first side 311 and a second side 312, which are opposite. The first surface 311 of the substrate 31 is a surface of the substrate 31 away from the electronic device body, that is, the first surface 311 is a surface of the substrate 31 away from the display screen 20. The second surface 312 of the substrate 31 is a surface of the substrate 31 contacting the electronic device body, that is, the second surface 312 is a surface of the substrate 31 facing the display panel 20.

The pattern layer 32 is formed on the second surface 312 of the substrate 31, i.e. the pattern layer 32 is formed on the surface of the substrate 31 facing the display panel 20. Specifically, the pattern layer 32 may be formed on the second surface 312 of the base material 31 by transfer, spray, dip, or the like. The pattern layer 32 can be made of colored colloid, so that the pattern layer 32 forms a color texture effect, the battery cover 30 is gorgeous in texture color, and the appearance expressive force of the electronic device is improved.

In the embodiment of the present application, the pattern layer 32 is made of colored glue and is used to form the texture pattern of the battery cover 30, so that the battery cover 30 has rich and vivid texture colors. For example, the pattern layer 32 may be made of a colloid with at least one of various colors such as blue, red, gold, pink, green, black, white, etc., and a texture pattern is formed so that the pattern layer 32 may have a rich and vivid color texture effect.

The embodiment of the application provides an electronic equipment's casing forms the pattern layer through the colloid that adopts the band color in the one side of substrate to make the pattern layer can have abundant bright-colored colour texture effect, and then realize the splendid texture color of casing outward appearance, promote electronic equipment's outward appearance expressive force.

The applicant further researches and discovers that the material granularity of the pattern layer has certain influence on the appearance performance of the shell, and the fineness of the texture pattern is influenced when the material granularity of the pattern layer is too large. Based on this, the granularity of the material of the pattern layer in the embodiment of the present application is generally controlled within 10 μm. Specifically, in the examples of the present application, the particle diameter of the colored colloid does not exceed 10 μm. Of course, in other embodiments, the particle size of the colored colloid can be controlled within 10 μm. The embodiment of the application controls the granularity or the particle size of the material of the pattern layer, so that the appearance of the shell color is more exquisite, and the use experience of a user is improved.

Further, the colored colloid includes glue and nano color paste, that is, the colored colloid is generally prepared by mixing the glue and the nano color paste, the color of the nano color paste is adjusted according to the required color, and then the colored colloid is prepared by mixing the nano color paste and the glue according to a certain proportion. Specifically, the nano color paste and the glue are matched to enable the pattern lines of the texture patterns of the pattern layer to be finer and finer. The nano color paste is generally prepared by uniformly mixing a colored nano toner and a solvent. Wherein, the solvent can be water or other solvents.

For example, when the nanometer color paste of the Tuhaojin color is needed, yellow toner, red toner, blue toner and a solvent can be mixed to prepare the nanometer color paste of the Tuhaojin color. When the rose-gold-color nano-color paste is needed, the yellow toner, the purple toner and the solvent can be mixed to prepare the rose-gold-color nano-color paste. Of course, for the nano color pastes of other colors, the nano toner of the corresponding color can be prepared according to the specific color requirement, which is not always mentioned in the embodiment of the present application.

The glue can be substantially instant glue, epoxy glue, anaerobic glue, ultraviolet light curing glue, hot melt glue, pressure sensitive glue, latex glue, etc., according to the specific characteristics of the glue. In the embodiment of the application, an epoxy resin adhesive or an ultraviolet curing adhesive is generally used to be matched with the nano color paste to prepare a colored colloid. Wherein the epoxy resin glue is waterproof, oil-proof, strong acid and alkali resistant, and can be cured at room temperature; the ultraviolet curing glue (UV glue) has wide application range, excellent bonding effect on bonding of plastics and various materials, high bonding strength, and high curing speed, and can be cured within seconds to tens of seconds. Preferably, in the embodiment of the present application, the colored colloid is preferably prepared by using an ultraviolet light curing adhesive and a nano color paste.

For example, when the color paste is prepared by matching the nanometer color paste with the color of the local tyrant gold and the ultraviolet curing glue, the texture pattern of the pattern layer can present the local tyrant gold color. When the color colloid is prepared by matching the rose gold color nano color paste with the ultraviolet curing adhesive, the texture pattern of the pattern layer can present the rose gold color.

The embodiment of the application provides a casing of electronic equipment makes the colloid of taking the colour through adopting glue and nanometer mill base cooperation, can be so that the pattern layer demonstrates rich bright-coloured colored texture effect, and then realizes the gorgeous texture color of casing outward appearance, promotes electronic equipment's outward appearance expressive force.

Based on this, the particle size of the material of the semi-permeable layer in the embodiment of the present application is generally controlled within 20 μm. Specifically, in the present embodiment, the particle diameter of the material of the semipermeable layer does not exceed 20 μm. Of course, in other embodiments, the granularity of the material of the semi-permeable layer can be controlled within 20 μm.
