[0030] Please refer to Figure 1-Figure 3 , Figure 1 A three-dimensional structural diagram of a decorative component provided in one embodiment of the present application. Figure 2 for Figure 1 A partial enlarged view of the middle decorative layer. Figure 3 A schematic structural diagram of a decorative element provided in one embodiment of the present application.

[0031] The present embodiment provides a decorative part 1, which includes a substrate 11 and a decorative layer 12 covering at least one side of the substrate 11, wherein a decorative crack 121 is provided on a surface of the decorative layer 12 facing away from the substrate 11, wherein the decorative crack 121 includes a plurality of sub-cracks 1211, wherein the plurality of connected sub-cracks 1211 form a decorative crack group, wherein in the decorative crack group, at least one sub-crack 1211 extends in a different direction from another sub-crack 1211; and the number of the decorative crack groups is multiple, wherein the sub-cracks 1211 of one decorative crack group are connected to or overlap with the sub-cracks 1211 of another decorative crack group.

[0032] The decorative piece 1 provided in this embodiment includes a substrate 11 for carrying a decorative layer 12. Optionally, the material of the substrate 11 can be metal, for example, aluminum. Optionally, the substrate 11 is in a strip shape. The decorative piece 1 provided in this embodiment also includes a decorative layer 12 for decorative purposes. The decorative layer 12 covers at least part of the outer surface of the substrate 11. Optionally, the decorative layer 12 can be an anodized film. The surface of the decorative layer 12 facing away from the substrate 11 is provided with a decorative crack 121, and the decorative crack 121 can give the user different visual perceptions at different angles.

[0033] For example, the substrate 11 is an aluminum substrate 11, and the decorative layer 12 is an aluminum anodized film. Specifically, by utilizing the difference in linear expansion coefficients between the aluminum substrate 11 and the aluminum anodized film, the aluminum substrate 11 is first anodized, and then the product is baked at a high temperature to cause the oxide film to crack to form a lattice-like appearance, thereby obtaining the decorative part 1 provided in this embodiment.

[0034] The decorative crack 121 includes a plurality of sub-cracks 1211. Optionally, the sub-cracks 1211 may be straight or curved. The decorative crack 121 includes individual sub-cracks 1211 and also includes interconnected sub-cracks 1211. Among them, the connected multiple sub-cracks 1211 form a decorative crack group. In other words, the connected multiple sub-cracks 1211 form a decorative crack group. Optionally, in a decorative crack group, the multiple sub-cracks 1211 are connected in sequence, and each sub-crack 1211 extends in a different direction. Optionally, in a decorative crack group, the multiple sub-cracks 1211 are connected end to end in sequence, and each sub-crack 1211 extends in a different direction. Optionally, in a decorative crack group, the multiple sub-cracks 1211 include a main crack, and a secondary crack connected to the main crack, and the main crack and another secondary crack extend in different directions.

[0035] Furthermore, there are multiple decorative crack groups. The sub-cracks 1211 of one decorative crack group overlap with the sub-cracks 1211 of another decorative crack group, which can be understood as one sub-crack 1211 not only forms one decorative crack group with some sub-cracks 1211, but also forms another decorative crack group with another part of sub-cracks 1211, that is, one sub-crack 1211 is shared by two decorative crack groups. The sub-cracks 1211 of one decorative crack group are connected to the sub-cracks 1211 of another decorative crack group, which can be understood as the sub-cracks 1211 of one decorative crack group are connected to the sub-cracks 1211 of another decorative crack group.

[0036] Since the decorative cracks 121 are provided on the decorative layer 12 of the present embodiment, when the light source is weak or viewed from a straight angle, the visual perception of the decorative member 1 is basically the same as that of the decorative member 1 of the related art. When the light is sufficient or at a specific angle, the decorative layer 12 of the decorative member 1 is visually similar to a lattice shape, for example, similar to the visual perception of rime.

[0037] Therefore, in this embodiment, by providing decorative cracks 121 on the surface of the decorative layer 12 facing away from the substrate 11 , different visual perceptions are given to users at different angles, so as to improve the decorativeness of the decorative part 1 and the appearance of the decorative part 1 .

[0038] Please refer to Figure 1-Figure 3 In one embodiment, a plurality of the decorative crack groups are arranged in an array; and / or a plurality of the decorative crack groups are arranged in a staggered manner.

[0039] For example, the decorative crack groups are arranged in an array in a part of the decorative layer 12. For another example, the decorative crack groups are arranged in a staggered manner in a part of the decorative layer 12. For another example, the decorative crack groups are arranged in an array and staggered in a part of the decorative layer 12. The decorative crack groups of this embodiment can be arranged in an array and / or staggered, so that the decorative element 1 can bring a richer visual experience to the user at different angles, so as to further improve the decorativeness of the decorative element 1 and further improve the appearance of the decorative element 1.

[0040] Please refer to Figure 1-Figure 3 In one embodiment, there is a gap between the sub-crack 1211 and the surface of the decorative layer 12 facing the substrate 11 ; and / or, the sub-crack 1211 runs through the surface of the decorative layer 12 facing the substrate 11 .

[0041] For example, the sub-crack 1211 does not penetrate the decorative layer 12, and there is a gap between the bottom of the sub-crack 1211 and the substrate 11. For another example, the sub-crack 1211 penetrates the surface of the decorative layer 12 facing away from the substrate 11 and the surface of the decorative layer 12 facing the substrate 11. For example, some of the sub-cracks 1211 do not penetrate the decorative layer 12, and some of the sub-cracks 1211 penetrate the surface of the decorative layer 12 facing the substrate 11.

[0042] The sub-crack 1211 of this embodiment may not penetrate the decorative layer 12 and / or penetrate the decorative layer 12, so that the decorative part 1 can bring users richer visual experience at different angles, so as to further improve the decorativeness of the decorative part 1 and further improve the appearance of the decorative part 1.

[0043] Please refer to Figure 1-Figure 3 In one embodiment, along the arrangement direction of the substrate 11 to the decorative layer 12 (eg Figure 3 As shown in the middle direction D), the thickness ratio of the substrate 11 to the decorative layer 12 is (10000-20000):(20-24).

[0044] Optionally, the thickness of the substrate 11 (eg Figure 3 H1 in the figure) is 10 mm to 20 mm. Further optionally, the thickness of the substrate 11 is 10 mm, or 12 mm, or 14 mm, or 16 mm, or 18 mm, or 20 mm, etc.

[0045] The thickness of the substrate 11 is selected to be 10 mm-20 mm, which is not only convenient to prepare, but also the thinner substrate 11 is more easily deformed by heat, so that the decorative layer 12 generates decorative cracks 121 to achieve a lattice effect.

[0046] Optionally, the thickness of the decorative layer 12 (eg Figure 3H2 in FIG. 1 is 20 μm to 24 μm. Further optionally, the thickness of the decoration layer 12 is 20 μm, or 21 μm, or 22 μm, or 23 μm, or 24 μm, etc.

[0047] In the related art, the thickness of the decorative layer 12 of the decorative piece 1 is usually 8μm-10μm, and a small amount of thin or fine textures will be formed in an environment with too high temperature, which affects the appearance. In this embodiment, by increasing the thickness of the decorative layer 12 to 20μm-24μm, the thicker decorative layer 12 is more likely to produce film cracks, and then baked at a higher temperature to achieve a dense crack effect with natural texture lines. In addition, due to the thicker thickness of the decorative layer 12, the texture reflects light in the case of sufficient light, forming an effect similar to rime on the surface of the decorative piece 1.

[0048] Specifically, the decorative layer 12 of the decorative part 1 needs to be powered during its generation process. The generation process of the decorative layer 12 is a process of corrosion and generation. The current is sufficient in the early stage, and the generation speed of the decorative layer 12 is greater than the corrosion speed. The decorative layer 12 increases. Since the decorative layer 12 itself is not conductive, its conductivity becomes worse during the process of increasing the thickness of the decorative layer 12. Finally, a balance point is reached, and the generation speed of the decorative layer 12 decreases. Its dissolution speed is consistent with the generation speed, and the decorative layer 12 no longer thickens. If the thickness of the decorative layer 12 is to be further increased, the following methods can be used: 1. Increase the voltage to increase the current density on the surface of the product; 2. Control the temperature. Oxidation is an exothermic process. The temperature will affect the generation of the decorative layer 12. The temperature of the oxidation tank can be lowered by a refrigerator to make the generated decorative layer 12 thicker.

[0049] Please refer to Figure 1-Figure 4 , Figure 4 A schematic diagram of the structure of a decorative layer 12 provided in one embodiment of the present application. In one embodiment, the decorative layer 12 includes a first portion 122, and a second portion 123 that is farther away from the substrate 11 than the first portion 122, the second portion 123 includes a surface of the decorative layer 12 that is away from the substrate 11, the first portion 122 and the second portion 123 are both provided with the decorative crack 121, the decorative crack 121 also includes a laser crack provided in the second portion 123, the laser crack connects the multiple sub-cracks 1211 and is obtained by laser processing.

[0050] The second part 123 is engraved by laser, and the lattice effect is more abundant. On the basis of the original decorative crack 121 of the second part 123, the original decorative crack 121 can be deepened and widened, and a new laser crack is generated on the second part 123. The second part 123 can also be understood as a laser engraving layer. Therefore, the second part 123 of this embodiment is processed by laser technology, and the high temperature of the laser will intensify the film crack effect of the decorative layer 12, so that the lattice effect is strengthened, and a new laser crack can be formed on the decorative layer 12 by laser, and a custom pattern can be customized to enrich the appearance effect.

[0051] Please refer to Figure 1-Figure 4 In one embodiment, along the arrangement direction from the substrate 11 to the decoration layer 12 , the second portion 123 accounts for 30%-60% of the thickness of the decoration layer 12 .

[0052] Optionally, along the arrangement direction from the substrate 11 to the decorative layer 12, the thickness of the second portion 123 (eg Figure 4 H3 in FIG. 1 is 6 μm-13 μm. Further optionally, the thickness of the second portion 123 is 6 μm, or 7 μm, or 8 μm, or 9 μm, or 10 μm, or 11 μm, or 12 μm, or 13 μm, etc.

[0053] The laser engraving depth of the decorative layer 12 is controlled at 30% to 60% of the thickness of the decorative layer 12, which can ensure the texture effect without completely penetrating the decorative layer 12 to expose the color of the substrate 11. In addition, the high temperature of the laser will intensify the film cracking effect of the decorative layer 12 and enhance the lattice effect. The crack texture pattern engraved by the laser can be defined by oneself to enrich the appearance effect.

[0054] Please refer to Figure 5 , Figure 5 A schematic structural diagram of a decorative element 1 provided in another embodiment of the present application. In one embodiment, the decorative element 1 further comprises a protective layer 13 , wherein the protective layer 13 covers the surface of the decorative layer 12 away from the substrate 11 and covers the decorative crack 121 .

[0055] Optionally, the material of the protective layer 13 may be varnish. Varnish is a coating composed of resin as the main film-forming substance and solvent. Since both the coating and the coating film are transparent, it is also called transparent coating. When applied to the surface of an object, it forms a smooth film after drying, showing the original texture of the object surface. Further optionally, the material of the protective layer 13 may be automotive grade varnish.

[0056] Since the surface performance of the decorative layer 12 will be greatly reduced after the film cracks, if the decorative part 1 is used as an exterior part, a protective layer 13 can be provided to protect the decorative layer 12 and extend the service life of the decorative part 1. In addition, if the decorative part 1 is used as an interior part, the requirements for varnish can be reduced.

[0057] Please refer to Figure 5 In one embodiment, along the arrangement direction from the substrate 11 to the decorative layer 12, the thickness ratio of the decorative layer 12 to the protective layer 13 is (20-24): (5-15).

[0058] Optionally, along the arrangement direction from the substrate 11 to the decorative layer 12, the thickness of the protective layer 13 (eg Figure 5 H4 in FIG. 1 is 5 μm-15 μm. Further optionally, the thickness of the protective layer 13 is 5 μm, or 6 μm, or 7 μm, or 8 μm, or 9 μm, or 10 μm, or 11 μm, or 12 μm, or 13 μm, or 14 μm, or 15 μm, etc.

[0059] Please refer to Figure 6 , Figure 6 A schematic diagram of the structure of a decorative element 1 provided in another embodiment of the present application. In one embodiment, the decorative layer 12 includes a first side surface 1241 and a second side surface 1242 that are arranged opposite to each other, and the decorative element 1 also includes a light emitting portion 14, and the light emitting portion 14 is arranged on one side of the first side surface 1241 and / or one side of the second side surface 1242.

[0060] This embodiment arranges light-emitting components around the decorative layer 12 to expand the light source effect of the light-emitting components, and links the decorative component 1 with the light source. Changes in the color of the light source will cause the lattice effect of the decorative component 1 to present different colors, further enhancing the decorative effect.

[0061] The present application also provides a vehicle, comprising glass, and a decorative element as provided above in the present application, wherein the decorative element is mounted on the glass.

[0062] Optionally, the glass may be a front windshield, a side window glass, a corner window glass, a rear windshield, etc. The vehicle provided in this embodiment adopts the decorative part provided in the present application, and the decorative part provides a decorative crack on the surface of the decorative layer away from the substrate, so as to bring different visual perceptions to the user at different angles, thereby improving the decorativeness of the decorative part and improving the appearance of the decorative part.
