In the housing of the electronic device, by setting the millimeter-level three-dimensional texture on the inner surface, the user can intuitively see a strong three-dimensional effect when viewing with the naked eye. The three-dimensional texture effect can be felt, and the casing can give the user a strong three-dimensional effect from the visual and tactile aspects at the same time, which meets the requirements of fashion and personalization, and enables the user to have a good use experience.

It should be noted that the description methods "millimeter-level first three-dimensional texture" and "millimeter-level second three-dimensional texture" used in this document mean that the dimensions of the first three-dimensional texture and the second three-dimensional texture in at least one dimension are in the millimeter level, That is, the size in at least one dimension may be 0.1 mm to 10 mm, for example, the height of the three-dimensional texture or the line width of the three-dimensional texture may be in the order of millimeters, or the height of the three-dimensional texture or the line width of the three-dimensional texture may be in the order of millimeters.

It can be understood that the specific material of the casing body is not particularly limited, as long as it is a material suitable for the casing of an electronic device. Specifically, the material of the housing body can be glass, ceramics, etc. Therefore, the material has a wide range of sources, the price is low, and there is no signal shielding problem, which can meet the use requirements of 5G. In some specific embodiments, the material of the housing body is glass. As a result, the material source is wide, the optical performance is good, and the cost is low.

It can be understood that the above-mentioned first three-dimensional texture and second three-dimensional texture may each independently include a plurality of texture surfaces, at least a part of the texture surfaces intersect, and the R angle at the intersection of the two texture surfaces is greater than or equal to 0.2 mm. 0.5mm～3mm, more specifically 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.8mm, 1.0mm, 1.2mm, 1.3mm, 1.8mm, 2.0mm, 2.2mm, 2.5mm, 2.8mm, 3.0 mm etc. Therefore, the first three-dimensional texture and the second three-dimensional texture have obvious angular structures, the appearance effect is more three-dimensional, the visual impact is stronger, and it is more fashionable and individual, which can bring a better user experience.

It should be noted that the description method "R angle" in this paper refers to the radius of the transition arc at the intersection of the two texture surfaces, and the specific schematic diagram refers to Fig. 3; A three-dimensional texture and a second three-dimensional texture can independently satisfy a certain parameter range, which means that the specific values of the parameter of the first three-dimensional texture and the second three-dimensional texture do not affect each other, that is, the specific value of the parameter of the first three-dimensional texture The value and the specific value of the parameter of the second three-dimensional texture may be the same or different.

It can be understood that, referring to FIGS. 1 , 2 and 4 , the above-mentioned first three-dimensional texture 22 and second three-dimensional texture 24 may be convex to the outside of the housing body 10 , and may also be recessed to the interior of the housing body 10 . Choose the look you want to achieve. In some specific embodiments, referring to FIGS. 1 and 2 , the first three-dimensional texture 22 is recessed toward the inside of the housing body 10 , and the second three-dimensional texture 24 is convex toward the outside of the housing body 10 . As a result, the inner surface of the housing body is easier to assemble with other components of the electronic device, which improves the space utilization rate, facilitates the miniaturization of the electronic device, and avoids bumping, scratching and other damage to the three-dimensional texture during the assembly process. , the finished product yield is higher, and the appearance effect is better. The second three-dimensional texture on the outer surface bulges outward, and the user can directly feel the three-dimensional effect when touching. Users can meet fashion and personalized requirements with a fresher and more impactful experience.

Specifically, the specific shapes and sizes of the first three-dimensional texture and the second three-dimensional texture are not particularly limited, and can be flexibly selected according to actual needs. In some specific embodiments, referring to FIG. 5 and FIG. 6 , the first three-dimensional texture and the second three-dimensional texture independently include at least one of linear stripes, curved stripes, geometric figures and irregular figures. Thereby, a richer and more beautiful appearance effect can be achieved, and the user experience can be improved.

Specifically, the cross-sectional shape of each first three-dimensional texture and each second three-dimensional texture can also be varied. In some specific embodiments, the cross-section of each first three-dimensional texture and the cross-section of each second three-dimensional texture The shapes can be independently triangles (refer to Figures 1, 2 and 4), trapezoids (refer to Figure 7), rectangles (refer to Figure 8), secant circles (refer to Figure 9) and other planar geometric figures and irregular figures (refer to Fig. 10). Thereby, a more diverse three-dimensional appearance can be provided. It should be noted that a secant circle refers to one of two parts formed by cutting a circle by a straight line, that is, two parts are formed after a circle is cut by a straight line, and each part can be called a secant circle.

Specifically, the specific size of the first three-dimensional texture and the second three-dimensional texture in the casing of the electronic device is millimeter level (0.1mm-10mm). The wavelength difference is relatively obvious, and there is basically no optical effect such as interference and diffraction, which allows users to directly experience a strong stereoscopic visual impact. Specifically, the height of the first three-dimensional texture may be less than or equal to the height of the second three-dimensional texture. Specifically, the first three-dimensional texture located on the inner surface is mainly used to observe the three-dimensional effect with the naked eye, and a small texture height can be effectively recognized by the naked eye, which is easy to process, facilitates the assembly of other components in the electronic device, and helps to reduce the thickness of the housing body. Thickness makes the shell thinner and lighter, and the second three-dimensional texture on the outer surface is used to give users a three-dimensional visual impact and directly feel the three-dimensional appearance effect when the user holds the electronic device. In order to ensure a more obvious three-dimensional touch, The height of the second three-dimensional texture can be made relatively large.

In some specific embodiments, the height H1 of the first three-dimensional texture may be 0.1-1 mm (specifically, such as 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm) , 1.0mm, etc.); the height H2 of the second three-dimensional texture can be 0.5-2.5mm, specifically 0.5-2mm, more specifically 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.1 mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2.0mm, etc.

It should be noted that the description method used in this article "the height of the three-dimensional texture" refers to the depth of the three-dimensional texture concave to the inside of the shell body or the height of the three-dimensional texture to the outside of the shell body. There is a three-dimensional texture on the surface as an example to illustrate that when the three-dimensional texture is concave to the inside of the housing body, the part other than the concave three-dimensional texture constitutes a convex part, and the inner surface of the convex part is located in a plane or an arc surface (refer to 1, 2 and 4), the height of the three-dimensional texture refers to the depth of the hollow of the three-dimensional texture relative to the above-mentioned plane or arc surface inside the housing body. In the same way, when the three-dimensional texture protrudes to the outside of the shell body, the part other than the raised three-dimensional texture constitutes a concave part, and the concave part is located in a plane or an arc surface, and the height of the three-dimensional texture refers to the three-dimensional texture relative to the above The height at which the plane or arc protrudes toward the exterior of the housing body.

In some specific embodiments, the line width W1 of the first three-dimensional texture and the line width W2 of the second three-dimensional texture may independently be greater than or equal to 1 mm, specifically may be 1-10 mm, more specifically may be 1 mm, 2 mm , 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, etc. It should be noted that the first three-dimensional texture and the second three-dimensional texture may independently include multiple texture lines, and the width of each texture line is within the above range, but the widths may be the same or different. Within this range, the three-dimensional effect is stronger, the appearance effect is better, and it is easy to process. If it is too small, the processing difficulty will increase, and the texture may be collapsed and damaged. If it is too large, it is not conducive to achieving a more diverse appearance. Effect.

It can be understood that the first three-dimensional texture and the second three-dimensional texture may be independent continuous textures (refer to FIG. 6 ), or may be multiple textures arranged at intervals (refer to FIG. 7 ). In some specific embodiments, the first three-dimensional texture and the second three-dimensional texture may independently include a plurality of sub-textures arranged at intervals, and the distance L between two adjacent sub-textures is greater than or equal to 1 mm, and may be 1 to 1 mm. 15mm, more specifically 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, etc. As a result, the texture spacing can be flexibly set as required to achieve a variety of appearance effects.

In some specific embodiments, referring to FIG. 2 , the maximum thickness D1 of the housing body 10 may be 3 to 10 mm (specifically may be 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, etc.), and the The minimum thickness D2 of the housing body 10 may be greater than or equal to 0.4mm (specifically, it may be 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm , 9mm, etc.). Therefore, while realizing the three-dimensional texture, it can not only ensure the strength requirements of the electronic device casing during use, but also meet the development trend of light and thin.

It should be noted that, since at least one of the bottom wall and the side wall has a three-dimensional texture on the inner surface and the outer surface, that is, the inner surface and the outer surface are both non-planar, the thickness of the shell body at different positions can be Different (non-equal thickness), the maximum thickness of the housing body refers to the thickness at the position where the thickness of the housing body is the largest, and the minimum thickness of the housing body refers to the thickness at the position where the thickness of the housing body is the smallest. In other embodiments, the thicknesses of different positions of the housing body may be approximately the same (equal thickness), referring to FIG. 11 , that is, the three-dimensional texture of the inner surface of the housing body and the protrusions of the three-dimensional texture on the outer surface of the housing body In cooperation with the depression, the three-dimensional texture of the inner surface protrudes to the outside of the shell body, then the three-dimensional texture of the outer surface at the corresponding position is concave to the inside of the shell body, and the three-dimensional texture of the inner surface is concave to the inside of the shell body. Then the three-dimensional texture of the outer surface at the corresponding position protrudes to the outside of the housing body.

In addition, the orthographic projections of the first three-dimensional texture and the second three-dimensional texture in the thickness direction of the shell body may not overlap at least partially, so that both the first three-dimensional texture and the second three-dimensional texture can be directly seen by the user, which can enrich the shell body appearance. In some specific embodiments, the orthographic projections of the first three-dimensional texture and the second three-dimensional texture in the thickness direction of the casing body may not overlap at all, or may partially overlap and partially overlap. Further, the first three-dimensional texture and the second three-dimensional texture can also be superimposed together to form a completed decorative pattern. For example, the first three-dimensional texture can form a pattern of stars, and the second first texture can form a pattern of planets such as the moon and the sun. They are superimposed together to form decorative patterns of the sky, etc.

It can be understood that, referring to FIG. 12 , the electronic device housing may further include: a decorative film 30 , and the decorative film 30 is disposed on the inner surfaces of the bottom wall 12 and the side wall 14 . As a result, the decorative diaphragms can achieve appearance decoration effects of different colors, different patterns, etc., so that the appearance of the casing is more diverse and dazzling, and better meets the user's aesthetic requirements.

It can be understood that the decorative film can be a multi-layer structure, and can specifically include a color layer, a texture layer, a cover bottom ink layer and a necessary adhesive layer, etc., and can also include a substrate film, the above-mentioned color layer, texture layer, cover bottom An ink layer and the like are formed on the base film in advance, and then attached to the inner surface of the casing. The specific decorative film structure, material, etc. can be selected according to the actual needs of the appearance effect, which will not be repeated here.

The steps are not limited in sequence. A part of the base material can be removed first to form a second three-dimensional texture, and then the outer surface corresponding to the side wall can be processed into an arc surface, or the outer surface corresponding to the side wall can be processed into an arc surface first. Then, a part of the substrate is removed to form a second three-dimensional texture, which can be flexibly adjusted as required.

It can be understood that the above method may further include: processing the outer surface of the base material at the position corresponding to the bottom wall into an arc surface. Thereby, a casing having a 3D structure can be formed. Specifically, this step may be performed before the formation of the second three-dimensional texture, or may be performed simultaneously with the formation of the second three-dimensional texture.

Specifically, before the second CNC processing, the substrate processed by the first CNC is fixed on a jig, and the surface of the jig in contact with the substrate has a complementary texture to the first three-dimensional texture The profiling three-dimensional texture, so that the first three-dimensional texture can be fixed in the profiling three-dimensional texture. In this way, the substrate formed with the first three-dimensional texture can be better fixed, and the profiling three-dimensional texture can be well matched with the first three-dimensional texture without damaging the first three-dimensional texture.

It should be noted that the description method used in this article "the profiling three-dimensional texture complementary to the first three-dimensional texture" means that the profiling three-dimensional texture is complementary to the first three-dimensional texture, and specifically refers to the position corresponding to the substrate and the fixture.
