[0032] Battery covers on electronic devices protect the batteries inside.

[0033] During the manufacturing process, the battery cover is textured by transferring the texture from the textured paper onto the cover.

[0034] However, the limited texture of the paper resulted in a monotonous visual effect for the battery cover.

[0035] The inventors of this application have discovered that a structural component can be provided, which may include a base layer and one or more target layers stacked on the base layer. The target layers may have a first region and a second region. The first region may have a textured portion of a target height, and the second region may have a target color. The textured structure corresponding to the textured portion can be etched onto a roller, and the target color can be sprayed onto the roller. This allows the roller to roll over the raw material layers used to create the target layers on the base layer, thereby simultaneously forming the textured portion and the target color. Different rollers can be configured with different combinations of textures and colors, enabling the rolling of different texture and color combinations onto the multiple raw material layers used to create the target layers on the base layer. This gives the structural component a combination of multiple textures and colors. When the structural component is used in a battery cover, it can enrich the textured effect of the battery cover and provide a visually appealing color effect, thus enhancing the visual appeal of the battery cover.

[0036] First aspect

[0037] This disclosure provides a structural component 10, see [link to details]. Figures 1 to 6 As shown, the structural component 10 may include: a base layer 11 and at least one target layer 12, the at least one target layer 12 being stacked on the base layer 11, the target layer 12 having at least a first region 121 and a second region 122, the first region 121 having a texture portion 1211 of a target height, and the second region 122 having a target color 1221.

[0038] The base layer 11 has at least one plane to allow the target layer 12 to be stacked on top of it. The base layer 11 can be the basic support layer of the entire structural component 10. When the base layer 11 is the basic support layer of the entire structural component 10, the base layer 11 can be made of metal materials (such as aluminum, copper, aluminum alloy, magnesium alloy, metal materials with added nanoparticles, etc.) or composite materials (such as polyester fiber, carbon fiber, thermoplastic polyurethane, polyurethane, etc.) to provide sufficient support strength and stability to the target layer 12 and other layered structures.

[0039] The target layer 12 has at least a first region 121 and a second region 122 (and may also have a third region, a fourth region, etc.). The first region 121 and the second region 122 may at least partially overlap, or they may not overlap at all. The texture portion 1211 is an uneven structure on one side and / or both sides of the target layer 12. That is, the texture portion 1211 of the first region 121 may be located on the same side of the target layer 12, or it may be located on different sides of the target layer 12. Texture portions 1211 located on the same side can form a specific shape (e.g., Figure 1(The clouds shown in the diagram); the height of the texture portion 1211 on the same target layer 12 can be consistent or not completely consistent. For example, the height of the texture portion 1211 on one side of the target layer 12 is ±1 / 2 of the thickness between the two surfaces of the target layer 12, while the height of the texture portion 1211 on the other side of the target layer 12 is ±1 / 3 of the thickness between the two surfaces of the target layer 12. The target color 1221 can be a single color (such as one of white, black, red, orange, yellow, green, cyan, blue, and purple), or it can be a mixture of multiple single colors (such as a mixture of two or more of white, black, red, orange, yellow, green, cyan, blue, and purple). The colors at different positions in the second region 122 can be consistent or inconsistent. In the case of inconsistency, a pattern can be formed. The target layer 12 can be made of an adhesive material so that it can be bonded to the base layer 11 when it is stacked on top of the base layer 11. Alternatively, the target layer 12 can be made of a non-adhesive material so that an adhesive layer or other connector can be pre-installed on the base layer 11 before the target layer 12 is stacked on top of the base layer 11 to fix the target layer 12. The target layer 12 can also be fixedly connected to the base layer 11 in other ways.

[0040] In one example, structural component 10 may include: a base layer 11 and at least one target layer 12, the at least one target layer 12 being stacked on the base layer 11, the target layer 12 having at least a first region 121 and a second region 122, the first region 121 having a texture portion 1211 of a target height, and the second region 122 having a target color 1221.

[0041] One method for manufacturing the structural component 10 includes:

[0042] S101: Prepare a thermoplastic polyurethane layer (TPU) as the base layer 11;

[0043] S102: After heating, a viscous polyurethane layer (PU) is prepared as the raw material layer for making a target layer 12. The raw material layer is laminated and bonded to the base layer 11. A first roller with an etched textured structure and sprayed with color is used to roll the raw material layer so that the raw material layer forms a target layer 12 with a textured part 1211 of a target height and a target color 1221.

[0044] S103: Prepare a heat-heated, viscous polyurethane layer as the raw material layer for making another target layer 12. Lay the raw material layer onto the target layer 12 in S102 and roll it on the raw material layer using a second roller with an etched texture and sprayed with color. The texture and color of the first roller and the second roller are not exactly the same.

[0045] In this embodiment, the structural component 10 may include a base layer 11 and a target layer 12. The first region 121 of the target layer 12 has a texture portion 1211 of a target height, and the second region 122 has a target color 1221. When the target layer 12 is stacked on the base layer 11, the structural component 10 has a texture portion 1211 of a target height and a target color 1221, thereby enriching the visual effects of the structural component 10 in terms of both three-dimensionality and color. Furthermore, when there are multiple target layers 12, and the texture portions 1211 and target colors 1221 of different layers are not completely consistent, the visual effects of the structural component 10 in terms of both three-dimensionality and color can be further enriched. When the structural component 10 is installed on the casing of the electronic device 15 (including but not limited to the battery cover and back cover of the electronic device 15), the casing of the electronic device 15 can have a dual visual effect of texture portion 1211 and color, and multiple target layers 12 can further increase the three-dimensionality and color.

[0046] In some embodiments, see Figure 1 As shown, at least a portion of the first region 121 and at least a portion of the second region 122 overlap, the textured portion 1211 has a plurality of roller pressing points 123, and at least a portion of the roller pressing points 123 are provided with a target color 1221.

[0047] In other words, the texture portion 1211 may have a partial or complete target color 1221, so that the same position on the target layer 12 can have a composite visual effect of the texture portion 1211 and the color. The texture portion 1211 has multiple roller pressing points 123, and some or all of the roller pressing points 123 are provided with the target color 1221, so that the same position on the target layer 12 can have a composite visual effect of the texture portion 1211 and the color, and the multiple roller pressing points 123 with the target color 1221 can cooperate to form a target pattern, which can be an interesting animal image, a brand logo of the structural component 10, or other settings.

[0048] In some embodiments, see Figures 3 to 5 As shown, the texture portions 1211 of different target layers 12 are at least partially misaligned; and / or, the target colors 1221 of different target layers 12 are at least partially misaligned.

[0049] In other words, the number of target layers 12 is multiple, and the texture portions 1211 of different target layers 12 are at least partially misaligned; or, the number of target layers 12 is multiple, and the target colors 1221 of different target layers 12 are at least partially misaligned; or, the number of target layers 12 is multiple, and the texture portions 1211 of different target layers 12 are at least partially misaligned and the target colors 1221 of different target layers 12 are at least partially misaligned.

[0050] When there are multiple target layers 12, and the texture portions 1211 of different target layers 12 are at least partially misaligned, multiple target layers 12 can be stacked on the base layer 11 of the structural member 10. Furthermore, in the multiple target layers 12, the orthographic projection of the texture portion 1211 of one target layer 12 onto another target layer 12 does not completely correspond to the texture portion 1211 of that other target layer 12. Thus, a texture portion 1211 at a certain position on the structural member 10 can correspond to a single target layer 12, or it can be formed by combining the texture portions 1211 of multiple target layers 12. Therefore, by misaligning the texture portions 1211 of the multiple target layers 12, the structural member 10 can possess a rich three-dimensional effect.

[0051] When there are multiple target layers 12, and the target colors 1221 of different target layers 12 are at least partially misaligned, multiple target layers 12 can be stacked on the base layer 11 of the structural component 10. In the multiple target layers 12, the orthographic projection of the target color 1221 of one target layer 12 onto another target layer 12 does not completely correspond to the target color 1221 of that other target layer 12, and the target colors 1221 of the two target layers 12 may be the same or different. Thus, the color at a certain position on the structural component 10 can originate from a single target layer 12 or from a mixture of colors from multiple target layers 12. Therefore, by misaligning the target colors 1221 of multiple target layers 12, the structural component 10 can have rich color effects.

[0052] See one example. Figures 3 to 5 As shown, a cover 14 is provided with a structural component 10, which includes a base layer 11 and two target layers 12. The textured portions 1211 on the two target layers 12 are circular protrusions and M-shaped protrusions, respectively, so that the cover 14 forms a superimposed texture effect of circular protrusions and M-shaped protrusions. Here, during the fabrication of the two target layers 12, the portions corresponding to the circular protrusions can be black, and the portions corresponding to the M-shaped protrusions can be white, so that the structural component 10 has a black and white superimposed texture effect; the textured portions 1211 can also be at least one of the following: English letters, numbers, Chinese characters, geometric images, etc.

[0053] In this article, the term "and / or" is merely a description of the relationship between related objects, identifying three possible relationships, such as A and / or B. Specifically, it can be understood as: A and B can be included simultaneously, A can exist alone, or B can exist alone, and any of the above three situations can be met.

[0054] In some embodiments, see Figure 2As shown, the first region 121 includes at least: a first sub-region 1212 and a second sub-region 1213; the first sub-region 1212 has a first texture with a first target height in the direction close to the base layer 11; the second sub-region 1213 has a second texture with a second target height in the direction away from the base layer 11; the first texture and the second texture are combined to give the textured portion 1211 of the first region 121 a three-dimensional effect. Alternatively, the textured portion 1211 of the target layer 12 may include a first texture protruding towards the base layer 11 and a second texture protruding on the side away from the base layer 11, so that the texture form of the structural component 10 can be diverse. Here, the first target height and the second target height can be completely consistent or not completely consistent; for example, the first target height may be greater than the second target height, to diversify the texture effect and give it a three-dimensional effect.

[0055] In some embodiments, the first sub-region 1212 and the second sub-region 1213 are connected; or, a second region 122 is provided between the first sub-region 1212 and the second sub-region 1213. That is, different textures can be connected to each other or spaced apart, so that the texture settings of the structural member 10 can have different settings.

[0056] In some embodiments, the second region 122 includes a third sub-region and a fourth sub-region; the third sub-region has a first target color; the fourth sub-region has a second target color; wherein the third sub-region and the fourth sub-region are connected; or, a first region 121 is located between the third sub-region and the fourth sub-region. Alternatively, the target color 1221 of the second region 122 can include multiple types, located at different positions, and the different target colors 1221 can be interconnected or spaced apart, allowing the target colors 1221 of the structural member 10 to have different configurations. The first target color and the second target color can be completely identical or not completely identical; for example, the first target color may be black, and the second target color may be a black and white alternating pattern.

[0057] In some embodiments, see Figure 1 As shown, the structural component 10 may further include: a functional layer 13, which is stacked on the side of at least one target layer 12 facing away from the base layer 11, and has at least one of the following functions: waterproof function, smooth function, and hydrophobic function.

[0058] When the functional layer 13 has a waterproof function (such as a nano-waterproof coating), the structural component 10 becomes waterproof, reducing the probability of water vapor and other liquids entering the interior of the electronic device 15 when it is placed outside the electronic device 15. When the functional layer 13 has a smoothing function (such as a tactile oil made of silicone-based materials), the structural component 10 has a smooth surface, reducing friction and improving the user's tactile experience. When the functional layer 13 has a hydrophobic function (such as being made of siloxane, nanostructures, or other materials), the surface of the structural component 10 placed on the outer surface of the electronic device 15 has the ability to repel water molecules, reducing the probability of water molecules penetrating into the interior of the electronic device 15.

[0059] In some embodiments, see Figure 1 As shown, the base layer 11 is a thermoplastic polyurethane layer, and the target layer 12 is a polyurethane layer; and / or, the orthographic projection of the target layer 12 onto the base layer 11 coincides with the base layer 11, and the orthographic projection of the functional layer 13 onto the target layer 12 coincides with the target layer 12.

[0060] The thermoplastic polyurethane (TPU) layer possesses excellent mechanical properties, chemical resistance, and processing flexibility, enabling the base layer 11 to provide a good foundation support for the target layer 12. The polyurethane (PU) layer, when heated, becomes malleable, allowing the textured structure and color on the rollers to be rolled onto the polyurethane layer to form the target layer 12 with textured areas 1211 and a target color 1221. Furthermore, the polyurethane layer is durable, extending the service life of the target layer 12.

[0061] When the orthographic projection of the target layer 12 onto the base layer 11 coincides with the base layer 11, and the orthographic projection of the functional layer 13 onto the target layer 12 coincides with the target layer 12, the surrounding surface of the functional layer 13, the surrounding surface of the target layer 12, and the surrounding surface of the base layer 11 have a flush visual effect.

[0062] Second aspect

The target layer 12 is stacked on the base layer 11. The target layer 12 has at least a first region 121 and a second region 122. The first region 121 has a texture portion 1211 of a target height, and the second region 122 has a target color 1221.

[0064] The cover 14 can be a structure of the electronic device 15 itself, such as the front shell and back shell of the electronic device 15 working together to form the internal space of the electronic device 15. The cover 14 can be the front shell, back shell, etc.; the cover 14 can also be a protective shell independent of the electronic device 15, which can be put on the electronic device 15 and can be removed from the electronic device 15.

The structural member 10 includes a base layer 11 and a target layer 12 which is stacked on the base layer 11 and has a texture portion 1211 with a target height and a target color 1221, so that the cover 14 has a dual effect of texture and color.
