The present disclosure provides an apparatus housing applied to an electronic apparatus. Fig. 1 is a schematic cross-sectional structure diagram of an apparatus housing in an exemplary embodiment of the present disclosure, fig. 2 is an effect diagram of an outer surface of an apparatus housing in an exemplary embodiment of the present disclosure, fig. 3 is one of enlarged structure diagrams of an outer surface of an apparatus housing in an exemplary embodiment of the present disclosure, fig. 4 is a second enlarged structure diagram of an outer surface of an apparatus housing in an exemplary embodiment of the present disclosure, and as shown in fig. 1 to fig. 4, the apparatus housing 1 includes a light-transmitting substrate 11 and at least one set of decoration units 12. The light-transmissive substrate 11 includes an inner surface 112 and an outer surface 111 disposed opposite to each other, the outer surface 111 is provided with protrusions 1111 and recesses 1112, the recesses 1112 are recessed with respect to the protrusions 1111, and the protrusions 1111 and the recesses 1112 are combined to form a predetermined grain pattern. At least one group of the decoration units 12 is disposed on the inner surface 112, and the decoration effect of the decoration units 12 is transmitted from the outer surface 111.

Wherein the inner surface 112 and the outer surface 111 may be oppositely disposed with respect to the thickness direction of the apparatus case 1.

Because the device housing 1 includes the light-transmitting substrate 11 and the decoration unit 12, the protrusion 1111 and the recess 1112 disposed on the outer surface 111 of the light-transmitting substrate 11 may be combined to form a predetermined texture pattern, the decoration effect of the decoration unit 12 may also be exposed from the outer surface 111, and the predetermined texture pattern on the outer surface 111 of the light-transmitting substrate 11 and the decoration effect of the decoration unit 12 exposed from the outer surface 111 cooperate to form the appearance of the device housing 1, thereby improving the visual effect and the touch experience of the device housing 1.

In the above embodiment, the texture pattern formed by the combination of the protrusions 1111 and the recesses 1112 may be at least one of a feather shape, a snowflake crystal shape, or an X-shaped leaf shape. In some embodiments, the texture pattern that the protrusions 1111 and the recessions 1112 may combine to form may consist of a single feather-like shape, a single snowflake-like crystal shape, a single X-shaped leaf-like shape, or a single other shape. In other embodiments, as shown in fig. 5-7, protrusions 1111 and recessions 1112 may combine to form a textured pattern comprising at least two of the above-described shapes. For example, as shown in FIG. 7, the protrusions 1111 and the depressions 1112 may be combined to form a textured pattern including a feather-like, a snowflake-like, and an X-shaped trefoil-like pattern.

It should be noted that when the texture pattern is composed of a single feather shape, a single snowflake crystal shape, a single X-shaped leaf shape, or other single shapes, the single shapes may be spaced apart from each other or may be stacked on each other to form at least a portion of overlapping texture patterns. When the texture pattern comprises texture patterns of at least two of the shapes, the shapes can be arranged at intervals, or can be overlapped with each other to form at least one partially overlapped texture pattern. For example, protrusions 1111 and recessions 1112 may combine to form a textured pattern comprising feathered, snowflake crystalline, and X-shaped trefoil patterns that overlap to form a textured pattern effective for recessions 1112.

Wherein, the feather-like, snowflake-like and X-shaped leaf-like patterns may be complete feather-like, snowflake-like and X-shaped leaf-like patterns, and may also be partial feather-like, snowflake-like and X-shaped leaf-like patterns, which is not limited by the disclosure.

In the above embodiment, the texture pattern formed by the combination of the protrusions 1111 and the recesses 1112 may be obtained by chemical etching to improve the processing convenience and the pattern aesthetic property of the texture pattern.

The Ra range value of the roughness of the outer surface 111 can be greater than or equal to 0.7um, and less than or equal to 3.5um, so that the roughness of the outer surface 111 improves the touch texture of the device shell 1 and the friction force of the outer surface 111 of the device shell 1, and the device shell 1 is prevented from sliding off in the using process.

The haze of the outer surface 111 may be greater than or equal to 25% and less than or equal to 65% to achieve the desired effects of the gloss, transparency, and degree of image formation of the outer surface 111.

In some embodiments, the transparent substrate 11 may be made of one of glass, sapphire, transparent polymer, and transparent composite material, but is not limited thereto. For example, the light-transmitting substrate 11 may be silicate glass, which is mainly silica and has good thermal stability, mechanical strength and hardness. Alternatively, the light-transmitting substrate 11 may be polyethylene terephthalate (PET), Polycarbonate (PC), polymethyl methacrylate (PMMA), or a composite material of Polycarbonate (PC) and polymethyl methacrylate (PMMA). The thickness of the light-transmitting substrate 11 may range in value from greater than or equal to 0.1mm to less than or equal to 5 mm. For example, the thickness of the light-transmitting substrate 11 may be 0.1mm, 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, but is not limited thereto.

In some embodiments, the decoration unit 12 may include a texture layer 121 and a light reflection layer 122 stacked, and under the reflection action of the light reflection layer 122, the texture of the texture layer 121 is reflected to the outer surface 111 to form a decoration effect. The decoration unit 12 can be fixed on the inner surface 112 of the light-transmitting substrate 11 by bonding, and is used for decorating the device shell 1, so that the attractiveness of the device shell 1 is improved, and the visual experience of a user is further improved. Specifically, light enters from the side where the light-transmitting substrate 11 is located, sequentially passes through the light-transmitting substrate 11 and the texture layer 121, and irradiates on the light-reflecting layer 122, the light-reflecting layer 122 reflects the light back, and sequentially passes through the texture layer 121 and the light-transmitting substrate 11, and under the reflection action of the light-reflecting layer 122, the texture of the texture layer 121 is reflected to the outer surface 111, so that the texture effect is presented on the light-transmitting substrate 11, and the function of beautifying the device shell 1 is achieved.

Note that the texture of the texture layer 121 includes at least one of lines, letters, numbers, letters, and images. At least two of lines, letters, numbers, letters, and images may be used in combination, or one of them may be used alone. When a plurality of lines, letters, numbers, letters, and images are used in combination, a more diversified, richer texture effect can be presented on the device case 1. For example, the texture of the texture layer 121 forms at least one of a pile texture, a text texture, and a photo-shadow texture by one or more of the above lines, letters, numbers, letters, and images.

In some embodiments, the light reflecting layer 122 is located on the lower side of the texture layer 121 in the incident direction of the light, and the texture layer 121 is closer to the inner surface 112 than the light reflecting layer 122. Thus, when light is incident from the light-transmitting substrate 11, the light sequentially passes through the light-transmitting substrate 11 and the texture layer 121 to irradiate the light reflection layer 122, then is reflected back by the light reflection layer 122 and passes through the texture layer 121 and the light-transmitting substrate 11 again, and in the process of light incidence and reflection, the texture layer 121 is penetrated by the light twice, so that the texture of the texture layer 121 can be clearly projected to the outer surface 111, and the display effect of the texture is better.

The light reflection layer 122 may be a plating layer formed by magnetron sputtering or evaporation, which has strong adhesion and is not easy to fall off. The plating material may be made of a laminate of silicon oxide, niobium oxide, and silicon nitride. The texture layer 121 may be formed by laser engraving die transfer. The thickness of the texture layer 121 is greater than or equal to 0.008mm and less than or equal to 0.05 mm. For example, the thickness of the textured layer 121320 may be, but is not limited to, 0.008mm, 0.01mm, 0.02mm, 0.03mm, 0.04mm, 0.05 mm.

In some embodiments, the decoration unit 12 may further include a film layer 123 disposed on a side of the texture layer 121 opposite to the light reflection layer 122, and the texture layer 121 is attached to a side surface of the film layer 123 opposite to the inner surface 112. The film layer 123 is used as a support carrier of the texture layer 121, which is beneficial to flattening the texture layer 121 and prevents wrinkles and falling off. For example, the film layer 123 can be made of polyethylene terephthalate, and the film layer 123 made of the material has smooth and glossy surface, excellent physical and mechanical properties in a wide temperature range, long-term service temperature of 120 ℃, excellent electrical insulation, good electrical properties even at high temperature and high frequency, good creep resistance, fatigue resistance, friction resistance and dimensional stability. Of course, the film layer 123 is not limited to the use of polyethylene terephthalate.

In one embodiment, the inner surface 112 of the light-transmissive substrate 11 may be provided with a set of decorative elements 12 to achieve a desired texture effect through the set of decorative elements 12. In another embodiment, the inner surface 112 of the light-transmitting substrate 11 may be provided with a plurality of sets of decorative elements 12 to achieve a desired texture effect through the superposition of the plurality of sets of decorative elements 12. The patterns of the texture layers 121 of any two decoration units 12 in the plurality of groups of decoration units 12 may be the same or different, and the disclosure does not limit this.

For example, when there are multiple groups of decoration units 12, the multiple groups of decoration units 12 are all disposed on the same side of the inner surface 112 and are sequentially arranged along the thickness direction of the light-transmitting substrate 11, and two adjacent decoration units 12 are adhered and fixed to each other. So set up, among the multiunit decoration unit 12, every group decorates unit 12 and all includes texture layer 121, then the texture of a plurality of texture layers 121 can superpose each other to, because a plurality of texture layers 121 are in different layers respectively, then the texture projection of each texture layer 121 is different to the light and shade degree of printing opacity base member 11, makes the texture effect after the stack more three-dimensional. In the embodiment shown in FIG. 2, the light reflecting layer 122 of one set of decorative elements 12 is adjacent to and adhesively secured to the film layer 123 of another set of decorative elements 12.

When the texture layers 121 of each set of decoration units 12 are the same, the same texture layers 121 of each set of decoration units 12 can be overlapped with each other to present a more three-dimensional texture effect. When the texture layers 121 of each set of decoration units 12 are different, the different texture layers 121 of each set of decoration units 12 can be overlapped with each other to present a richer texture effect.

For example, the decoration units 12 may be provided with two groups, which are the first decoration unit 12 and the second decoration unit 12, respectively, the texture layer 121 of the first decoration unit 12 is a villus texture, and the texture of the texture layer 121 of the second decoration unit 12 may be at least one of lines, letters, numbers, characters and images, so that the villus texture can be superimposed on the lines, letters, numbers, characters or images to present a multi-style texture effect.

It should be noted that, the specific number of the decoration units 12 can be selected according to actual requirements, and the arrangement sequence of the decoration units 12 with different texture layers 121 is not limited.

In some embodiments, the device housing 1 further comprises a color layer 124, wherein the color layer 124 is disposed on a side surface of the light reflection layer 122 facing away from the texture layer 121. The color layer 124 can be used as a substrate to increase colors for the light-transmitting base body 11, so that the whole color effect is presented, the colors of the equipment shell 1 are richer, the attractiveness of the equipment shell 1 is further improved, and the texture layer 121 can be protected.

The color layer 124 may be an ink layer, for example, ink may be coated on the light reflection layer 122 by a screen printing method. The color of the ink layer is not limited, and may be orange, pink, blue, etc., and the configuration may be specifically selected according to actual needs. In this embodiment, the color layer 124 is disposed on a side of the decoration unit 12 opposite to the inner surface 112, and is coated on the light reflection layer 122 of the decoration unit 12 and farthest from the inner surface 112.

In some embodiments, the device housing 1 further comprises an optical cement layer 13, and the decoration unit 12 is adhered to the inner surface 112 by the optical cement layer 13. The optical adhesive layer 13 is colorless and transparent, has the light transmittance of more than 90 percent, has good bonding strength, can be cured at room temperature or intermediate temperature, has the characteristics of small curing shrinkage and the like, and is used for bonding transparent optical elements. The optical adhesive layer 13 may be provided in plurality. For example, the groups of decoration units 12 can be fixed by adhering with the optical adhesive layer 13.

The equipment shell 1 further comprises a hydrophobic oil-phobic layer 14, and the hydrophobic oil-phobic layer 14 is arranged on the outer surface 111. The hydrophobic oil-repellent layer 14 can reduce or even avoid the water-based and oil-based substances from remaining on the outer surface 111, and avoid fingerprint residues. The hydrophobic oil-repellent layer 14 may be made of nano-Silica (SiO) ₂ ) The coating is formed by adopting a spraying process and has good light transmission and hydrophobic and oleophobic properties. The hydrophobic oil-repellent layer 14 may also be referred to as an AF (Anti-fingerprint) layer.

The device housing 1 can be applied to the device housing 1 of a mobile terminal such as a mobile phone, a tablet personal computer, etc., the device housing 1 can obtain a preset texture pattern, and different colors can be added through the color layer 124, so that the texture pattern formed by the convex portion 1111 and the concave portion 1112 on the outer surface 111 of the light-transmitting substrate 11 of the device housing 1, the texture layer 121 of the decoration unit 12 and the color layer 124 are matched to obtain an appearance effect of a desired color, and the beauty and appearance quality of the mobile terminal are improved. In addition, the hydrophobic oil-repellent layer 14 can reduce fingerprints from remaining in the device shell 1, and keep the device shell 1 clean and tidy in use.
