Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0054] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or it can be in a middle component. When a component is said to be "connected" to another component, it can be directly connected to the other component or it may be in a middle component.

[0055] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. The terminology used in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0056] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0059] refer to Figure 1 and Figure 2 In the housing 100 provided in this application, the housing 100 includes a body 110 and a textured film 120, which are integrally connected. The body 110 includes a glass layer 111, an OCA (Optically Clear Adhesive) layer 112, a PET (Polyethylene Terephthalate) film layer 113, a coating layer 114, and an ink layer 115. The textured film 120 is made of one of the following materials: PP (Polypropylene), PVC (Polyvinyl Chloride), PET (Polyethylene Terephthalate), glass, and TPU (Thermoplastic Polyurethane Elastomer Rubber). The textured film 120 includes one or more texture units 121, which are combined and arranged to achieve different decorative effects.

The textured unit 121 includes a plurality of cones 121a, which are sequentially disposed on the substrate 122 along a first direction. The dimensions of at least a portion of the cones 121a in the first direction are different from those of another portion of the cones 121a in the first direction, and / or the dimensions of at least a portion of the cones 121a in the second direction are different from those of another portion of the cones 121a in the second direction. The first direction is different from the second direction, and there is an angle between the first direction and the second direction, which can be 80° to 100°. In this application, by setting texture units 121 on the surface of substrate 122, multiple cones 121a of texture units 121 are arranged sequentially along a first direction, and at least some cones 121a have different dimensions in the first direction than other cones 121a in the first direction and / or the second direction, so that multiple cones 121a are arranged in a certain pattern, and at least some cones 121a have different dimensions, and there are differences in light reflection between different cones 121a, which can make the texture film 120 have a stronger light and shadow texture, so that the pattern on the texture film 120 presents a three-dimensional depth effect in macroscopic vision.

[0061] The cone 121a includes one or more of the following: a cone, a triangular pyramid, a square pyramid, a pentagonal pyramid, and a hexagonal pyramid. In this embodiment, the cone 121a is described as a square pyramid; however, this is not a limitation in other embodiments. The square pyramid includes a base and multiple lateral faces connected to the base. The base includes a square, a rectangle, or a rhombus, and the lateral faces include planes (see reference). Figure 5 ) and / or curved surfaces (reference) Figure 6 ).

[0062] Specifically, at least a portion of the cone 121a may have dimensions in the first direction different from those of the other portion of the cone 121a in the first direction (see reference). Figure 7 ), or at least part of the cone 121a has a different dimension in the second direction than another part of the cone 121a in the second direction (see reference). Figure 8 ), or at least part of the cone 121a has dimensions in the first and second directions that differ from those of another part of the cone 121a in the first and second directions (see reference). Figure 9 All of these can make the texture unit 121 have a stronger sense of light and shadow.

[0063] In this application, the width direction of the texture unit of the substrate 122 is taken as the first direction X, the length direction of the texture unit of the substrate 122 is taken as the second direction Y, and the height direction of the texture unit of the substrate 122 is taken as the Z direction. That is, the first direction X is perpendicular to the second direction Y, and the Z direction is perpendicular to the plane containing the first direction X and the second direction Y.

[0064] The dimensions of any cone 121a in the first direction X and / or the second direction Y are 5μm-2000μm, and the height of any cone 121a is 5μm-1000μm; wherein, the height of any cone 121a is the dimension in the Z direction. For a cone 121a with a square or rectangular base, the side length of the base of the cone 121a is 5μm-2000μm, and for a cone 121a with a rhomboid base, the diagonal dimension of the base of the cone 121a is 5μm-2000μm.

[0065] Example 1

[0066] refer to Figure 4 , Figure 7 , Figure 8 and Figure 9The texture unit 121 includes m cones 121a in the first direction X, where m is an integer greater than or equal to 3. In the first direction X, the cone 121a located in the middle has a larger dimension in the first direction X than the cones 121a located on either side, and / or the cone 121a located in the middle has a larger dimension in the second direction Y than the cones 121a located on either side. Specifically, in the first direction X, the cone 121a located in the middle may have a larger dimension in the first direction X than the cones 121a located on either side (see reference). Figure 7 ), or the dimension of the cone 121a located in the middle in the second direction Y is greater than the dimension of the cones 121a located on both sides in the second direction Y (refer to Figure 8 ), or the size of the central cone 121a in the first direction X and the second direction Y is larger than the size of the cones 121a on both sides in the first direction X and the second direction Y (see reference). Figure 9 All of these can make the formed texture unit 121 visually present a raised depth effect.

[0067] Optionally, 8≤m≤40, and texture units 121 formed within this range of m have better depth of field effect.

[0068] refer to Figure 7 Where m is an odd number, the m cones 121a are sequentially named as the 1st cone 121a, the 2nd cone 121a, ..., the mth cone 121a in the first direction X. The size of the 1st to the (m+1) / 2nd cones 121a in the first direction X increases sequentially, and the size of the (m+1) / 2nd to the mth cones 121a in the first direction X decreases sequentially. Among them, the (m+1) / 2nd cone 121a is the cone 121a located in the middle of the m cones 121a. That is, among the m cones 121a in the first direction, the size of the cone 121a located in the middle is decreased sequentially towards the cones 121a located on both sides in the first direction, so as to further improve the overall depth effect of the texture unit 121.

[0069] Specifically, the dimensions of the first to (m+1) / 2th cones 121a in the first direction X satisfy a x1 =C*x1 R The dimensions of the (m+1) / 2th to the mth cone 121a in the first direction X satisfy a x2 =C*(m+1-x2) RWhere x1 represents any integer from 1 to (m+1) / 2, x2 represents any integer from (m+1) / 2 to m, C represents a positive zero constant in μm, and R represents a positive zero integer. Optionally, m is 9, C is 10 μm, and R is 2, that is, in the first direction, the dimensions of the nine cones 121a are 10 μm, 40 μm, 90 μm, 160 μm, 250 μm, 160 μm, 90 μm, 40 μm, and 10 μm, respectively.

[0070] In this embodiment, the size change of the m cones 121a in the first direction is a power function relationship, making the size change of any two adjacent cones 121a in the first direction more obvious, thereby making the protrusion depth-of-field effect of the texture unit 121 more obvious. In other embodiments, the size of the m cones 121a in the first direction may also be an exponential change or other change relationship.

[0071] Example 2

The dimensions of the 1st to the m / 2nd cones 121a in the first direction X increase sequentially, and the dimensions of the (m+2) / 2nd to the mth cones 121a in the first direction X decrease sequentially. The dimension of the m / 2nd cone 121a in the first direction X is equal to the dimension of the (m+2) / 2nd cone 121a in the first direction X. The m / 2nd and (m+2) / 2nd cones 121a are the two cones 121a located at the middle of the m cones 121a.

[0073] Specifically, the dimensions of the first to the m / 2th cones 121a in the first direction X satisfy a x3 =C*x3 R The dimensions of the (m+2) / 2th to the mth cone 121a in the first direction X satisfy a x4 =C*(m+1-x4) R Where x3 represents any integer from 1 to m / 2, x4 represents any integer from (m+2) / 2 to m, C represents a positive zero constant in μm, and R represents a positive zero integer. Optionally, m is 10, C is 10 μm, and R is 2, meaning that in the first direction X, the dimensions of the 10 cones 121a are 10 μm, 40 μm, 90 μm, 160 μm, 250 μm, 250 μm, 160 μm, 90 μm, 40 μm, and 10 μm, respectively.

In this embodiment, the texture unit 121 includes a plurality of cones 121a arranged along the first direction X and a plurality of cones 121a arranged along the second direction Y, thereby creating a depth-of-field effect with the edges bulging towards the center on the plane formed by the first direction X and the second direction Y.

[0076] Optionally, 8≤n≤40, and texture units with a number of n within this range will produce better depth of field effects.

The nth row of cones 121a in the second direction Y consists of the cones 121a in the 1st row, the cones 121a in the 2nd row, ..., the cones 121a in the nth row. The size of the cones 121a in the second direction Y increases sequentially from the 1st row to the (n+1) / 2th row, and decreases sequentially from the (n+1) / 2th row to the nth row. Among them, the cones 121a in the (n+1) / 2th row are the cones 121a in the middle row of the nth row. That is, among the nth row of cones 121a in the second direction, the size of the cones 121a in the middle row decreases sequentially towards the cones 121a in the two side rows in the second direction, so as to further improve the overall depth effect of the texture unit 121.

[0078] Optionally, the dimensional variation relationship of the plurality of cones 121a in the second direction Y from the 1st row to the (n+1) / 2nd row, and the dimensional variation relationship of the plurality of cones 121a in the second direction Y from the (n+1) / 2nd row to the nth row, are the same as the dimensional variation relationship of the plurality of cones 121a in the first direction X in Embodiment 1. Optionally, n is 10, C is 10μm, and R is 2, that is, in the second direction Y, the dimensions of the plurality of cones 121a in the 9 rows are 10μm, 40μm, 90μm, 160μm, 250μm, 160μm, 90μm, 40μm, and 10μm, respectively.

The dimensions of the multiple cones 121a in the second direction Y increase sequentially from the 1st row to the n / 2nd row, and the dimensions of the multiple cones 121a in the second direction Y decrease sequentially from the (n+2) / 2nd row to the nth row. The dimensions of the multiple cones 121a in the second direction Y in the n / 2nd row are equal to the dimensions of the multiple cones 121a in the (n+2) / 2nd row. The multiple cones 121a in the n / 2nd row and the (n+2) / 2nd row are the two middle rows of the multiple cones 121a in the nth row. Optionally, n is 10, C is 10μm, and R is 2, meaning that in the second direction Y, the dimensions of the multiple cones 121a in the 10 rows are 10μm, 40μm, 90μm, 160μm, 250μm, 250μm, 160μm, 90μm, 40μm, and 10μm, respectively.

After development, drying, plasma cleaning, and UV transfer, the texture is transferred onto PC sheets, PET sheets, or PC / PMMA composite materials to form the textured film 120. The textured film 120 is then laminated onto a glass shell through processes such as coating, printing, cutting, and bonding to create a glass sample with this texture. Alternatively, a PC mold can be made through processes such as exposure, development, and UV adhesive transfer, and then UV transfer is performed onto a PET explosion-proof film to form the textured film 120. After coating, printing, and bonding, it is then laminated onto glass to create a glass product. Or, the mold can be transferred onto a composite material and thermoformed to create a textured plastic sheet product.
