The decorative structure 14 is arranged in a preset area on the surface of the substrate 12. The decorative structure 14 includes a plurality of structural units 13 arranged in an array. Along the direction from the preset area to away from the substrate 12, the structural units 13 are in a contracted structure.

[0057] In the appearance part provided by the exemplary embodiment of the present disclosure, a decorative structure including a plurality of structural units arranged in an array is arranged in a preset area on the surface of the substrate, and these structural units are in a contraction-like structure along the direction away from the preset area to the substrate, that is, a plurality of structural units arranged in an array form a plurality of contraction-like protrusions in the preset area on the surface of the substrate, and the space between adjacent structural units forms a depression, so that an uneven structure is formed in the preset area on the surface of the substrate, which is the decorative structure of the appearance part. This uneven decorative structure makes the preset area on the surface of the substrate present a contraction-like protrusion texture, which can enrich the decorative effect of the appearance part on the one hand, and on the other hand, because the structural unit is in a contraction-like structure, the structure of the area connected to the substrate is relatively firm and will not be easily damaged. Even if damage occurs, only one or several structural units are damaged, which will not affect the overall appearance effect of the preset area, so that no obvious scratches will be produced, thereby avoiding affecting the appearance effect of the appearance part.

[0058] When the appearance parts provided by the exemplary embodiments of the present disclosure are applied to the camera surround decoration parts of electronic devices, the aesthetics and refinement of the camera surround decoration parts can be improved, the user experience can be improved, and in addition, obvious scratches caused by friction during the use of the electronic device can be avoided.

[0066] For example, Figure 3 In the top view of the appearance part 11 shown in the figure, the shape of each structural unit is a tetrahedral pyramid. The shape of each structural unit is, for example, a regular tetrahedral pyramid similar to the "Maya pyramid". The bottom surface of the regular tetrahedral pyramid is a square, and the lengths of the sides of the square bottom surface are equal, all of which are 0.05mm-3mm, for example, all of which are 0.27mm or all of which are 0.3mm.

For another example, each structural unit The shapes are all in the shape of a tetrahedral pyramid, the bottom surface of the tetrahedral pyramid is a rectangle, and the length of the rectangle is h, the width is i, or the length of the rectangle is i, the width is h, h and i are both in the range of 0.05mm-3mm, for example, h is 0.27mm, i is 0.3mm, or i is 0.27mm, h is 0.3mm, the top surface of the tetrahedral pyramid is a rectangle, and the length of the rectangle is j, the width is k, or the length of the rectangle is k, the width is j, j and k are both in the range of 0.05mm-3mm, for example, j is 0.15mm, k is 0.16mm, or k is 0.15mm, j is 0.16mm, and the side length of the top surface on the same cone surface is smaller than the side length of the bottom surface. Cut the appearance part along the section line g to obtain the following Figure 4 In the cross-sectional schematic diagram of the appearance component 11 shown in the figure, in two adjacent quadrangular pyramids, the angle n between the two opposite conical surfaces is 10°-170°, for example, the angle n can be 10°, 90°, or 170°; the height s of the quadrangular pyramid is 0.005mm-3mm, for example, the height s can be 0.005mm, 0.04mm, 1mm, or 3mm; the length i of one side of the bottom surface of the quadrangular pyramid is 0.05mm-3mm, for example, it can be 0.27mm; the length j of one side of the top surface is 0.05mm-3mm, for example, it can be 0.15mm, and j is smaller than i.

[0067] In the exemplary embodiments provided in the present disclosure, Figure 5As shown, the substrate 12 is a frame-shaped structure, which includes a first end face 10, an outer side face 30, and a connecting face 20 connecting the first end face 10 and the outer side face 30.

The preset area is at least located on the connecting face 20. The appearance part formed by the decorative structure is arranged on the inclined connecting face 20 of the substrate 12, and the texture is arranged on an unconventional plane, which can enhance the particularity of the appearance part. When the appearance part is applied to the camera periphery decoration of an electronic device, the beauty and refinement of the camera periphery decoration can be enhanced, and the user experience can be enhanced. In addition, it can also prevent obvious scratches on the electronic device due to friction during use.

[0068] In the exemplary embodiments provided in the present disclosure, Figure 6 As shown, the frame structure 60 includes a plurality of straight frames 80, and adjacent straight frames are connected by arc frames 70, so that the frame structure 60 has a rounded structure, which improves the softness and aesthetics of the appearance.

[0069] In an embodiment in which the shapes of the structural units in the preset area on the surface of the substrate are all polygonal pyramids, the vertices of the structural units located on the connecting surfaces of the same straight frame are located on the same plane, and the vertices of the structural units located on the connecting surfaces of the same arc-shaped frame are located on the same conical surface. In this way, the structural units in the preset area on the surface of the substrate can be made neat and beautiful, thereby improving the beauty and refinement of the appearance parts and reducing friction.
