[0021] The technical solution of the present application will be described in detail below with reference to the drawings.

[0022] Please refer to Figure 1A - Figure 7。An embodiment of the present application provides a workpiece. The workpiece 100 includes a substrate 10, and a texture layer 20 is provided on one side surface of the substrate 10. The texture layer 20 includes a plurality of first-level regions 21. The plurality of first-level regions 21 exhibit light and dark variations, and each first-level region 21 includes a plurality of structural units 22. At least a plurality of structural units 22 include a first structural unit and a second structural unit that are interconnected. The first structural unit includes a plurality of first texture strips arranged in sequence, and at least some ends of the first texture strips fall on the contour of the first structural unit. The second structural unit includes a plurality of second texture strips arranged in sequence, and at least some ends of the second texture strips fall on the contour of the second structural unit; at least some ends of the first texture strips are in contact with at least some ends of the second texture strips; each texture strip included in each structural unit is independently a convex structure.

[0023] In the present application, the above-mentioned first structural unit and second structural unit are any two connected structural units among the plurality of structural units. For the convenience of marking, in Figure 1A - Figure 5 each structural unit is marked as 21. Similarly, the first texture strip and the second texture strip are the texture strips in any two connected structural units respectively. For the convenience of marking, in Figure 5 each texture strip is marked as 221.

[0024] As Figure 2 - Figure 5 shown, the surface of the substrate 10 has a texture layer 20, and the texture layer 20 includes a plurality of first-level regions 21 that exhibit light and dark variations. The light and dark variations between different first-level regions are brought about by different extension directions of the texture strips within each first-level region. The extension directions of the texture strips within each first-level region are the same or similar. Specifically, each texture strip is independently a convex structure, and the convex structure has a plurality of light reflection angles. Different extension angles cause the light reflected by the convex structure at a certain fixed light angle to be different in light and dark. Thus, when the user observes the workpiece from a certain fixed angle, the surface of the workpiece can be divided into a plurality of first-level regions with different light and dark. When the user changes the observation angle, the light and dark of each first-level region will change accordingly, thereby bringing a rich visual experience to the user.

[0025] Also, since each first-level region 21 includes a plurality of structural units 22, and the first structural unit and the second structural unit are any two connected structural units among the plurality of structural units 22. At least some ends of the first texture strips or the second texture strips in both the first structural unit and the second structural unit fall on the outer contour of the structural unit, so that the above-mentioned first texture strips and second texture strips have the possibility of contacting each other. And at least some ends of the first texture strips are in contact with the ends of the second texture strips. At this time, these first texture strips and second texture strips can form a multi-segment curve.

[0026] For example, there is a first structural unit, which has m texture strips inside, one end of i first texture strips among the m texture strips is in contact with j second texture strips in the second structural unit, and the other end of k second texture strips among the i second texture strips is in contact with r first texture strips in another first structural unit (m, n, j, i, k, r are all integers, m≥2, n≥2, i≥1, j≥1, k≥1, r≥1 and their respective values ​​can be the same or different), so that at least one multi-segment curve composed of three texture strips 221 can be formed. Specifically, see Figure 5 There is a first structural unit B, one end of three first texture strips (b1, b2, b3) among the four texture strips in B is connected to the three second texture strips in the second structural unit A, wherein the other ends of b1 and b2 are also in contact with two first texture strips in the first structural unit C, respectively, thereby forming a plurality of multi-segment curves consisting of three texture strips. The structural units A and C have other structural units adjacent thereto, and so on, a multi-segment curve having more multi-segment curves consisting of different numbers of texture strips 221 can be formed, thereby forming multi-segment curves of different lengths. When the user observes the workpiece, each multi-segment curve resembles a hair.

[0027] In addition, from the above content, it can be seen that there must be some texture strips 221, and their extension directions are different (including similar or very different situations), which can cause each multi-segment curve to have different bending degrees, lengths, and extension directions, and ultimately make the surface of the workpiece present a hair-like pattern with rich layers.

[0028] In summary, the texture layer 20 on the surface of the workpiece 100 has different light and dark levels, which can present a dynamic effect like hair in a real state, that is, as the light and the viewing angle change, the hair texture pattern on the surface of the workpiece 100 also produces a light and dark alternating flow effect, which has multi-level and flexible characteristics, rich visual effects, and great artistic beauty. In addition, the surface of the workpiece 100 has many convex structures, and this concave-convex structure can reduce the contact area between the human hand and the workpiece surface, thereby achieving the effect of preventing hand sweat and fingerprint residue, so that it can still maintain a gorgeous appearance after long-term use.

[0029] In the present application, the shape of the primary area 21 can be regular or irregular, for example, circular, irregularly curved, annular, etc.

[0030] In this application, in some cases, Figure 2 - Figure 4 Both the dark stripes and the white stripes in the pattern may represent the texture strips 221 (ie, the raised structures). Figure 2 - Figure 4The dark stripe pattern therein represents the texture strip 221, and the white stripe pattern represents the interval between two adjacent texture strips 221 within the same structural unit 22. That is, the texture strips 221 within the above-mentioned structural unit 22 can be connected in one piece or arranged at intervals. However, in either case, there is a boundary between adjacent texture strips 221, and their surfaces are each covered with a convex structure.

[0031] In this application, the shape of the structural unit 22 is not specifically limited and can be a rectangle, a circle, a sector, a polygon, an irregular shape, etc., as long as a plurality of structural units 22 can fit together to form a continuous texture layer 20.

[0032] In this application, the mutual contact between the texture strips 221 can mean that the two texture strips 221 are completely connected, or it can mean that the two texture strips 221 are connected in a staggered manner, as long as there is an intersection between the two texture strips 221.

[0033] In some embodiments of this application, at least some of the two ends of the first texture strip are in contact with a plurality of second texture strips at the same time. The above-mentioned plurality of second texture strips can come from the same second structural unit or from different second structural units. It can be understood that at this time, a tree-branch-like structure is formed. Exemplarily, reference can be made to Figure 3 , Figure 3 wherein one end of the texture strip e is in contact with the texture strips f and f' at the same time, and the two multi-segment curves d-e-f and d-e-f' produce an intersection. When the user quickly changes the viewing angle, the above-mentioned hair-like pattern itself will produce a flowing effect, which can further enrich the visual effect of the workpiece.

[0034] In some embodiments of this application, each texture strip 221 within each structural unit 22 has a preset angle with a preset direction along its extending direction, and the preset angle is independently within the range of -90° to 90°. The above-mentioned preset direction refers to the length direction or the width direction of the workpiece 100 (specifically, the length or width direction of the substrate 10). When discussing the positional relationship of the texture strips 221 on a certain workpiece 100, each texture strip 221 needs to use one of the length direction and the width direction of the workpiece 100 as the preset direction at the same time. Specifically, taking Figure 5 as an example, Figure 5 the angle between the extending direction of the texture strip g and the preset direction is 0°, and the preset angle between the extending direction of the texture strip e and the preset direction is 90° (or -90°). When the user observes the workpiece 100 from a certain angle, when the preset angles of the texture strips 221 (that is, the convex structures) within a certain primary area are mostly within the range of -30° to 30° (see Figure 1A area A in Figure 2The first-level area marked in Figure 1A is area B in Figure 3 ; Understandably, when the preset angles of the texture bars 221 in a certain first-level area are mostly in the range of -90° to -60° or 60° to 90°, this first-level area is an obvious dark area (see Figure 1A area C in Figure 4 and the first-level area 21 marked in

[0035] In some embodiments of the present application, there are at least some first-level areas 21, and the preset angles of the respective texture bars 221 within a single first-level area 21 are in the range of -10° to 10°. There are also some first-level areas 21, and the preset angles of the respective texture bars 221 within a single first-level area 21 are in the range of 80° to 90° and / or -90° to -80°. At this time, the surface of the workpiece 100 has relatively prominent bright areas and dark areas, which is beneficial to further enrich the appearance of the workpiece 100. In addition, the curvature of the multi-segmented curves within the same first-level area 21 has a natural transition, making the hair texture of the workpiece 100 more natural and realistic.

[0036] In some embodiments of the present application, there are at least some first-level areas 21, and the preset angles of the respective texture bars 221 within a single first-level area 21 are in the range of -30° to 30° (denoted as first-level area X). There are also some first-level areas 21, and the preset angles of the respective texture bars 221 within a single first-level area 21 are in the range of 60° to 90° and / or -90° to -60° (denoted as first-level area Y). And there are also some first-level areas 21 at the same time, and the preset angles of the respective texture bars 221 within a single first-level area 21 are in the range of -60° to -30° and / or 30° to 60° (denoted as first-level area Z). At this time, the light and dark effects on the surface of the workpiece 100 are more abundant. In addition, it can also make the presented hair texture more natural and realistic.

[0037] In some embodiments of the present application, the above-mentioned first-level area Z is located between the first-level areas X and Y. At this time, the surface of the workpiece 100 simultaneously has a bright area, a dark area, and a transition area between the two, which can make the light and dark transition on the surface of the workpiece 100 more natural and the aesthetics higher.

[0038] In some embodiments of the present application, the width of the convex structure gradually decreases in the direction away from the substrate 10. At this time, when the user changes the viewing angle, the dynamic changing effect of the light and shadow of the workpiece is more obvious.

[0039] In some embodiments of the present application, the shape of the cross section of the protruding structure (the cross section is parallel to the thickness direction of the substrate 10) includes but is not limited to at least one of an arch and a polygon. The cross-sectional shapes of each protruding structure may be the same or different. Exemplarily, the above-mentioned polygon may be a triangle, a trapezoid, etc., and correspondingly, the shape of the protruding structure is a prism, a quadrangular prism, etc. It is sufficient that the protruding structure has multiple reflection angles when illuminated by light.

[0040] In some embodiments of the present application, the width of the raised structure is 2μm-100μm. Exemplarily, the width of the raised structure can be 2μm, 5μm, 7μm, 10μm, 15μm, 20μm, 25μm, 30μm, 40μm, 50μm, 60μm, 70μm, 80μm, 90μm, 100μm, etc. The width of each raised structure can be the same or different. At this time, the size of each raised structure is small. On the one hand, it can ensure that the number of raised structures in each structural unit 22 is large. On the other hand, the raised structure with a suitable size can better present a smooth hair-like pattern, ensuring that the workpiece 100 has a rich appearance. In addition, the raised structure of the above size is easier to prepare.

[0041] In some embodiments of the present application, the ratio of the maximum width to the length of the protrusion structure is 1:(5-20). The protrusion structure has a suitable aspect ratio, which is conducive to controlling the smoothness of the multi-segment curve (hair).

[0042] In some embodiments of the present application, the height of the protruding structure is less than or equal to the maximum width of the protruding structure, which is beneficial to the preparation of the workpiece 100 and to ensure the aesthetics of the workpiece 100 .

[0043] In some embodiments of the present application, a plurality of protruding structures are continuously arranged in the same structural unit 22. In this case, it is beneficial to ensure that the number of protruding structures in each structural unit 22 is as large as possible, so that the appearance of the workpiece 100 is more gorgeous.

[0044] In some embodiments of the present application, a plurality of raised structures are arranged at intervals in the same structural unit 22, and the spacing between two adjacent raised structures is less than the maximum width of the raised structure. In the same structural unit 22, the spacing between any two adjacent raised structures may be the same or different. The spacing between adjacent raised structures in different structural units 22 may be the same or different. The presence of spacing between each raised structure can reduce the density of the raised structure in the texture layer 20, further reducing the difficulty of the production process of the workpiece 100, but only with a suitable density can the workpiece 100 be guaranteed to have the appearance of a flowing hair-like pattern. A person of ordinary skill in the art can select the density of the raised structure according to actual production needs and customer needs, and can achieve the appearance effect of the workpiece 100.

[0045] In this application, there are no specific restrictions on the material and thickness of the substrate 10, which can be selected according to user requirements. Specifically, the material of the substrate 10 includes but is not limited to metals, glass, ceramics, polymer composite materials, etc.

[0046] In this application, the preparation method of the workpiece 100 can be a technical method well-known to those of ordinary skill in the art. In some specific embodiments, it includes the following steps:

[0047] (1) Prepare a mold with a texture layer structure through a photolithography process;

[0048] (2) Form a texture layer on the surface of the substrate to obtain the workpiece.

[0049] Specifically, a hair-like planar pattern can be pre-designed, and then, according to the light and dark characteristics of different regions of the planar pattern, layer decomposition is carried out using software. Then, texture structure parameters are set for each decomposed layer to design and complete a hair texture structure with a dynamic light and shadow change effect. Finally, the structure parameters of the above layers are translated into a photolithography data file, and the mold with the texture layer structure is obtained through photolithography.

[0050] Among them, the formation method of the texture layer on the surface of the substrate can be selected according to the material of the substrate. Exemplarily, processes such as UV transfer, in-mold injection molding, injection molding, glass lamination, chemical etching, optical coating, electroforming, etc. can be used.

[0051] The embodiment of this application also provides an electronic device, which is equipped with the workpiece 100 provided by the embodiment of this application. The above electronic devices include but are not limited to mobile phones, tablet computers, laptop computers, smart watches, electronic cigarettes, etc. Exemplarily, the workpiece 100 can be processed into the casings of mobile phones, tablet computers, and laptop computers, and can also be processed on relevant parts of electronic cigarettes, which can make the above electronic devices have a cool appearance effect and can improve the appearance expressiveness and product competitiveness of the electronic devices.

[0052] In addition, the workpiece 100 can also be processed into a luxury nameplate, which can further improve the artistry of the product.

[0053] The technical solution of this application will be described in detail below in combination with specific embodiments.

Among them, in each structural unit, the texture strips are arranged without intervals, and the protruding structure is a triangular prism, the width of the protruding structure is 10 μm, and the height is 1.5 μm.

[0064] Figure 10 - Figure 11 They are respectively the photo of the partial area of the mobile phone back cover in Example 1 under the microscope and the analysis of the texture structure size. Numerous structural units form the hair texture pattern of the shell back cover. Figure 1A - Figure 1C It is the grayscale image of the mobile phone back cover obtained in Example 1 at different viewing angles. It can be clearly seen that the hair pattern in the same area of the mobile phone back cover has brightness changes with the change of the viewing angle, and the hair lines of the pattern on the back cover are smooth, with multi-levelness and flexibility.
