[0038] As described in the background, conventional plastic covers are easily scratched, forming continuous and noticeable scratches on their surfaces, affecting their aesthetics and the user experience. This problem arises because the plastic cover lacks any scratch-resistant structure on its surface. The surface is flat and devoid of any other structures. When a hard object collides with the outer surface of the plastic cover, scratches are easily formed. Furthermore, due to the relatively flat surface, scratches are continuous, making them easily visible to users. This affects the aesthetics of the plastic cover and the user experience.

[0039] In response to the above technical problems, embodiments of the present application provide a plastic cover and a vehicle, the plastic cover comprising a main body, the surface of the main body being provided with a plurality of first protrusions, the plurality of first protrusions being spaced and evenly distributed on the surface of the main body, each first protrusion being further provided with a plurality of first protrusions, the plurality of first protrusions being spaced and evenly distributed on the outer surface of the first protrusion, the first protrusions, the first protrusions, and the main body being an integral injection molded structure. The provision of the plurality of spaced and evenly distributed first protrusions can reduce the probability of the surface of the main body coming into direct contact with hard objects, reduce the probability of the main body being scratched, and avoid forming continuous scratches on the main body. The provision of the plurality of first protrusions on the first protrusions allows the protrusions to first come into contact with hard objects, reducing the probability of the first protrusions contacting hard objects, thereby further reducing the probability of the surface of the main body being scratched, reducing the probability of the main body being scratched, reducing the impact of scratches on the aesthetics of the plastic cover, and improving the user experience.

[0040] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0041] With reference to Figures 1 and 2, an embodiment of the present application provides a plastic cover. The plastic cover may include a main body 100, with a plurality of first protrusions 200 disposed on the outwardly facing surface of the main body 100. The plurality of first protrusions 200 are spaced and evenly distributed on the surface of the main body 100. The first protrusions 200 and the main body 100 may be integrally formed. For example, the first protrusions 200 and the main body 100 may be integrally injection molded. By providing the first protrusions 200 and the main body 100 as an integrally formed structure, the connection stability between the first protrusions 200 and the main body 100 can be improved, and the strength and impact resistance of the first protrusions 200 can be improved.

[0042] 3 and 4 , if a hard object 400 moves along the upper edge of the plastic cover in a first direction (as indicated by arrow X in FIG3 ), scratches in the X direction will be formed on the plastic cover (as indicated by area A in the dotted box in FIG3 ). By providing a plurality of evenly distributed first protrusions 200 on the outward-facing surface of the main body 100 , the contact area between the main body 100 and the hard object 400 can be reduced, the probability of the surface of the main body 100 being scratched can be reduced, and continuous long scratches can be avoided from forming on the surface of the main body 100 of the plastic cover after the plastic cover is scratched. Compared with continuous long scratches, the recognition of the scratches can be reduced, the impact of the scratches on the aesthetics of the plastic cover is reduced, and the user experience is improved.

[0043] In some embodiments, the outward-facing surface of the main body 100 may also be provided with a patterned structure 110 of various shapes. In the embodiments of the present application, the first protrusions 200 may be of any shape, and the shapes of two adjacent first protrusions 200 may be the same or different. In a specific implementation, the projection of the first protrusions 200 onto the surface of the main body 100 may be in the shape of an ellipse, a circle, a polygon, or the like.

[0044] 2 , 3 and 4 , a plurality of first protrusions 210 are further provided on each first protrusion 200 . The plurality of first protrusions 210 are spaced and evenly distributed on the outer surface of the first protrusion 200 so that the first protrusions 210 contact the hard object 400 , thereby reducing the contact area between one first protrusion 200 and the hard object 400 , thereby reducing the contact area between the plastic cover and the hard object 400 , and further reducing the continuity of the scratches.

[0045] In some embodiments, the first protrusion 210, the first protrusion 200, and the main body 100 are integrally formed. For example, the first protrusion 210, the first protrusion 200, and the main body 100 can be an integral injection-molded structure. In some embodiments, each first protrusion 200 can be provided with multiple first protrusions 210. For example, the number of first protrusions 210 on a first protrusion 200 can be 1, 2, 3, 4, 6, 8, or even more. By providing multiple first protrusions 210 on the outer surface of the first protrusion 200, the contact area between the first protrusion 210 and the hard object 400 is increased, thereby improving the bearing capacity of the first protrusion 210 on the first protrusion 200 for the hard object 400 and preventing the first protrusion 210 from detaching from the first protrusion 200 due to excessive pressure.

[0046] An embodiment of the present application provides a plastic cover and a vehicle, the plastic cover including a main body 100, a surface of the main body 100 being provided with a plurality of first protrusions 200, the plurality of first protrusions 200 being spaced apart and evenly distributed on the surface of the main body 100, each first protrusion 200 being further provided with a plurality of first protrusions 210, the plurality of first protrusions 210 being spaced apart and evenly distributed on the outer surface of the first protrusion 200, the first protrusions 200, the first protrusions 210 and the main body 100 being an integral injection-molded structure. By providing a plurality of spaced and evenly distributed first protrusions 200, the probability of direct contact between the surface of the main body 100 and the hard object 400 can be reduced, and the probability of the main body 100 being scratched can be reduced, and continuous scratches can be avoided. By further providing a plurality of first protrusions 210 on the first protrusions 200, the protrusions can be made to contact the hard object 400 first, reducing the probability of contact between the first protrusions 200 and the hard object 400, thereby further reducing the probability of the surface of the main body 100 being scratched, reducing the probability of the main body 100 of the plastic cover being scratched, reducing the impact of scratches on the aesthetics of the plastic cover, and improving the user experience.

[0047] 3 , in some embodiments, the area of ​​the orthographic projection of each first protrusion 200 onto the surface of the main body 100 is greater than or equal to 1 mm 2 and less than or equal to 6mm 2 For example, the area of ​​the orthographic projection of the first protrusion 200 onto the surface of the main body 100 may be 1 mm 2 , 1.5mm 2 , 2mm 2 , 2.4mm 2 , 3mm 2 , 3.7mm 2 , 4mm 2 , 5mm 2 , 5.6mm 2The orthographic projection areas of different first protrusions 200 onto the surface of the main body 100 may be the same or completely different. If the orthographic projection area of ​​the first protrusions 200 onto the surface of the main body 100 is too large, the contact area between the first protrusions 200 and the hard object 400 will be too large, which may easily cause continuous scratches. In addition, the surface of the main body 100 may be too rough, affecting the appearance and the user experience.

[0048] 3 , the distance between each two adjacent first protrusions 200 (as shown by L in FIG3 ) is greater than or equal to 0.2 mm and less than or equal to 6 mm. In some embodiments, the distance L between each two adjacent first protrusions 200 can be 0.5 mm, 1 mm, 1.7 mm, 3 mm, 3.7 mm, 4.3 mm, 4.8 mm, or 5.5 mm. If the distance L between two adjacent first protrusions 200 is less than 0.2 mm, the distance L between the two adjacent first protrusions 200 will be too small, resulting in the first protrusions 200 being too densely distributed on the surface of the main body 100, and the effect of blocking the continuity of the scratch cannot be achieved.

[0049] Referring to Figure 4 , in one possible implementation, the outer surface of the first protrusion 200 is disposed facing away from the surface of the main body 100 and is curved. This curved outer surface of the first protrusion 200 reduces the contact area between the hard object 400 and the outer surface of the first protrusion 200, thereby reducing the area of ​​scratches caused by the hard object 400. Furthermore, this curved outer surface improves the uniformity of force applied to the outer surface of the first protrusion 200.

[0050] In some embodiments, the outer surface of the first protrusion 200 may be at least one of a circular arc surface, an elliptical arc surface, or a polygonal arc surface. The present application does not impose any specific limitation on the outer surface of the first protrusion 200.

[0051] Referring to Figure 4 , in one possible implementation, first protrusions 210 are disposed on the curved surface and extend away from the curved surface. The extension direction of first protrusions 210 is perpendicular to the surface where first protrusions 210 connect to the curved surface. By making the extension direction of first protrusions 210 perpendicular to the surface where first protrusions 210 connect to the curved surface, first protrusions 210 can extend in various directions, thereby allowing first protrusions 210 to bear forces in different directions.

[0052] Referring to FIG. 5 , in one possible implementation, the maximum distance H1 between the outer surface of the first protrusion 200 and the surface of the main body 100 (as shown in FIG. 5 ) is less than or equal to 250 μm. For example, the maximum distance H1 between the outer surface of the first protrusion 200 and the surface of the main body 100 may be 100 μm, 150 μm, 200 μm, or 230 μm. If the maximum distance H1 between the outer surface of the first protrusion 200 and the surface of the main body 100 is greater than 250 μm, the connection between the first protrusion 200 and the main body 100 may be less stable due to the high H1, thereby making it easier for the first protrusion 200 to fall off the main body 100.

[0053] Referring to FIG. 5 , in some embodiments, the maximum distance between the first bump 210 and the outer surface of the first protrusion 200 (as indicated by h1 in FIG. 5 ) is less than or equal to 100 μm. For example, the maximum distance h1 between the first bump 210 and the outer surface of the first protrusion 200 can be 30 μm, 60 μm, or 90 μm. If the distance h1 between the first bump 210 and the outer surface of the first protrusion 200 is too large, the first bump 210 may fall off the first protrusion 200, affecting the connection stability between the first bump 210 and the first protrusion 200, and further affecting the first bump 210's ability to support the hard object 400.

[0054] Based on the above embodiment, the area of ​​the orthographic projection of the first convex point 210 to the outer surface of the first protrusion 200 is less than or equal to 2 mm. 2 For example, the area of ​​the orthographic projection of the first convex point 210 to the outer surface of the first protrusion 200 may be 0.3 mm 2 , 0.5mm 2 , 0.8mm 2 , 1.3mm 2 , 1.7mm 2 In a specific implementation, the number of first bumps 210 that can be provided on one first protrusion 200 can be 5, 6, 7, 8 or even more.

[0055] Referring to Figure 6 , at least one second protrusion 300 is further provided on the outer surface of the first protrusion 200. When there are multiple second protrusions 300, the multiple second protrusions 300 are spaced and evenly distributed on the outer surface of the first protrusion 200. By providing the second protrusions 300 on the outer surface of the first protrusion 200, the plastic cover can contact the hard object 400 through the second protrusions 300. Compared to direct contact between the first protrusions 200 and the hard object 400, the distance between the second protrusions 300 on two adjacent first protrusions 200 is greater than the distance between two adjacent first protrusions 200, thereby further hindering the continuity of the scratch, reducing the clarity of the scratch and making it less noticeable, and reducing the impact of the scratch on the aesthetics of the plastic cover.

[0056] In an exemplary embodiment, the area of ​​the orthographic projection of the second protrusion 300 onto the outer surface of the first protrusion 200 is greater than or equal to 1 mm. 2 and less than or equal to 4mm 2 For example, the area of ​​the orthographic projection of the second protrusion 300 onto the outer surface of the first protrusion 200 may be 1 mm 2 , 1.5mm 2 , 2mm 2 , 3mm 2 , 3.3mm 2 .

[0057] At least one second protrusion 310 is provided on the second protrusion 300, which enables the hard object 400 to contact the second protrusion 310 on the second protrusion 300, thereby reducing the contact area between the second protrusion 300 and the hard object 400, thereby reducing the scratch area of ​​the hard object 400 on the second protrusion 300, and further reducing the overall scratch area on the main body 100.

[0058] There are multiple second protrusions 310, and the multiple second protrusions 310 are spaced and evenly distributed on the second protrusion 300. For example, two or three second protrusions 310 can be provided on one second protrusion 300. By providing multiple second protrusions 310 on the second protrusion 300, the support of the second protrusion 310 on the hard object 400 can be improved, the probability of the second protrusion 310 falling off the second protrusion 300 can be reduced, and the connection stability between the second protrusion 300 and the second protrusion 300 can be improved.

[0059] Referring to Figure 7 , the second protrusion 300 extends away from the outer surface of the first protrusion 200, and the extension direction of the second protrusion 300 is perpendicular to the surface where the second protrusion 300 connects to the first protrusion 200. In some embodiments, the outer surface of the second protrusion 300 may also be a curved surface, and the shape of the orthographic projection of the outer surface of the second protrusion 300 onto the first protrusion 200 can be the same as the shape of the orthographic projection of the outer surface of the first protrusion 200 onto the surface of the main body 100. By making the extension direction of the second protrusion 310 perpendicular to the surface where the second protrusion 310 connects to the curved surface of the second protrusion 300, the second protrusion 310 can extend in various directions, thereby allowing the second protrusion 310 to bear forces in different directions.

[0060] Referring to FIG8 , the maximum distance from the outer surface of the second protrusion 300 to the outer surface of the first protrusion 200 (as shown in H2 in FIG8 ) is less than or equal to 200 μm. For example, the maximum distance H2 from the outer surface of the second protrusion 300 to the outer surface of the first protrusion 200 can be 50 μm, 70 μm, 120 μm, or 180 μm. The size of the second bump 310 is the same as that of the first bump 210. In a specific implementation, the area of ​​the orthographic projection of the second bump 310 onto the outer surface of the second protrusion 300 is less than or equal to 1 mm. 2 For example, the area of ​​the orthographic projection of the second convex point 310 to the outer surface of the second protrusion 300 may be 0.3 mm 2 , 0.5mm 2 , 0.8mm 2 .

[0061] The present application also provides a vehicle, which may include a vehicle body and the above-described plastic cover. Using the above-described plastic cover on a vehicle can improve the scratch resistance of the plastic cover and reduce the continuity of scratches on the surface of the plastic cover, thereby reducing the clarity of scratches on the plastic cover, improving the aesthetics of the scratched plastic cover, and enhancing the user experience of the vehicle.
