Technical Field

[0001] The present application relates to the technical field of electronic products, and in particular to a shell structure and a processing method thereof, and an electronic device. Background Art

[0002] Electronic devices such as mobile phones, tablet computers, and laptop computers are provided with shell structures, such as the battery cover of mobile phones, the back shell of tablet computers, and the A shell, B shell, C shell, and D shell of laptop computers. These shell structures are used to protect the internal electronic components.

[0003] With the development of technology, more and more manufacturers design at least a part of the housing structure as a combination structure of a hard substrate and leather, with the leather covering the outer surface of the hard substrate, to improve the quality of electronic devices. However, due to the high price of leather, the cost of the housing structure and the electronic device is high. Summary of the invention

[0004] The present application provides a housing structure and a processing method thereof, and an electronic device, which can improve the quality of the electronic device while reducing the cost of the housing structure and the electronic device.

[0005] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0006] In a first aspect, a shell structure is provided, the shell structure comprising a substrate, a color layer and a first light-transmitting texture layer. The substrate has an outer surface. The color layer is disposed on at least a portion of the outer surface. The first light-transmitting texture layer is disposed on a side of the color layer facing away from the substrate, and a surface of the first light-transmitting texture layer facing away from the color layer and / or a surface of the first light-transmitting texture layer facing the color layer is provided with a first texture, the first texture being the same as the surface texture of leather.

[0007] In this way, the color layer provides the basic color of the imitation leather effect, and the first light-transmitting texture layer provides the texture of the imitation leather effect, so as to form an appearance with the imitation leather effect, thereby improving the quality of the housing structure and the electronic device. At the same time, the base, the color layer and the first light-transmitting texture layer can be made of low-cost materials, thereby improving the quality of the housing structure and the electronic device while reducing the cost of the housing structure and the electronic device.

[0008] Optionally, the material of the first light-transmitting texture layer is an elastic soft material. The elastic soft material is elastic and can produce a leather-like touch, thereby improving the touch of the housing structure and the electronic device.

[0010] Optionally, the material of the color layer is ink. The color adjustability of ink is good, and the required color can be mixed.

An optical coating layer is disposed on the side of the substrate facing away from the color layer, and at least a portion of the optical coating layer is opposite to the second area. In this way, the user can see the optical coating layer through the substrate, and the second area can present the appearance of the optical coating layer, so that the shell structure can present the appearance of a splicing of imitation leather and the optical coating layer, and thus the appearance performance is better.

[0014] Optionally, a portion of the optical coating layer is opposite to the first region, and another portion is opposite to the second region. In other words, a portion of the projection of the optical coating layer on the outer surface of the substrate is located in the second region, and another portion is located in the first region. In this way, the difficulty of setting the optical coating layer can be reduced, and the flatness of the inner surface of the housing structure can be improved.

[0015] Optionally, the optical coating layer is an indium tin alloy film layer, a silicon dioxide film layer, a titanium oxide film layer or a zirconium oxide film layer.

[0016] Optionally, the shell structure further includes a second light-transmitting texture layer, which is disposed between the substrate and the optical coating layer, and a second texture is disposed on a surface of the second light-transmitting texture layer facing the substrate and / or a surface of the second light-transmitting texture layer facing the optical coating layer. In this way, the second light-transmitting texture layer and the optical coating layer can provide a rich visual effect, and can achieve a diversified appearance effect of the shell structure.

[0017] Optionally, the second texture is a shiny sand texture, a matte texture or a glare texture.

[0021] The third light-transmitting texture layer is combined with the substrate, the second light-transmitting texture layer and the optical coating layer to provide richer visual effects.

[0022] Optionally, the third texture may be a glittering sand texture, or may be a frosted texture or a glare texture.

[0023] Optionally, the third light-transmitting texture layer and the first light-transmitting texture layer are an integral structural member. In this way, the shell structure is simple and the molding difficulty is low.

[0024] Optionally, the boundary line between the first region and the second region is the first boundary line, and the boundary line between the third light-transmitting texture layer and the first light-transmitting texture layer is the second boundary line. The projection of the second boundary line on the outer surface of the substrate is located within the first region, and the distance between the second boundary line and the first boundary line is less than or equal to 0.5 mm. In this way, the first boundary line and the second boundary line can be prevented from intersecting and affecting the appearance of the shell structure.

[0025] In a second aspect, an electronic device is also provided, the electronic device comprising a screen, a housing structure and a middle frame. The housing structure is a housing structure as described in any of the above technical solutions. The middle frame is located between the screen and the housing structure, and the screen and the housing structure are both connected to the middle frame.

[0026] Since the electronic device provided in the present application includes the housing structure as described in any of the above technical solutions, the two can solve the same technical problems and achieve the same effects.

[0029] Disposing a color layer on at least a portion of the outer surface of the substrate;

[0031] In this way, the color layer provides the basic color of the imitation leather effect, and the first light-transmitting texture layer provides the texture of the imitation leather effect, so as to form an appearance with the imitation leather effect, thereby improving the quality of the housing structure and the electronic device. At the same time, the base, the color layer and the first light-transmitting texture layer can be made of low-cost materials, thereby improving the quality of the housing structure and the electronic device while reducing the cost of the housing structure and the electronic device.

[0032] Optionally, the outer surface of the substrate includes a first area and a second area. Based on this, arranging the color layer on at least part of the outer surface of the substrate includes: arranging the color layer on the first area. In this way, arranging the color layer on the second area can reduce the area where the color layer is arranged, saving costs.

Based on this, the processing method further includes: arranging a second light-transmitting texture layer on a side of the substrate facing away from the color layer, and making at least a portion of the second light-transmitting texture layer face the second region; wherein the surface of the second light-transmitting texture layer facing the substrate, and / or the surface of the second light-transmitting texture layer facing away from the substrate, is provided with a second texture;

[0034] An optical coating layer is disposed on a side of the second light-transmitting texture layer facing away from the substrate, and at least a portion of the optical coating layer is opposite to the second region.

[0035] In this way, the second light-transmitting texture layer and the optical coating layer can provide rich visual effects and realize the diversification of the appearance effects of the shell structure.

[0036] Optionally, the processing method further includes: providing a base layer on the side of the optical coating layer facing away from the second light-transmitting texture layer. The base layer can protect the optical coating layer and prevent the optical coating layer from being scratched and affecting the appearance of the housing structure.

The present application is exemplified by an electronic device being a handheld device with a wireless communication function, and the handheld device may be, for example, a mobile phone.

[0061] See also Figure 1 and Figure 2 , Figure 1 A perspective view of an electronic device 100 provided in some embodiments of the present application, Figure 2 for Figure 1 Schematic diagram of the exploded structure of the electronic device 100 shown. In this embodiment, the electronic device 100 is in the shape of a rectangular flat plate. Based on this, in order to facilitate the following description, an XYZ coordinate system is established, and the length direction of the electronic device 100 is defined as the Y-axis direction, the width direction of the electronic device 100 is defined as the X-axis direction, and the thickness direction of the electronic device 100 is defined as the Z-axis direction. It can be understood that the coordinate system setting of the electronic device 100 can be flexibly set according to actual needs, and no specific limitation is made here. In some other embodiments, the shape of the electronic device 100 can also be a square flat plate, a circular flat plate, an elliptical flat plate, etc.

[0062] The electronic device 100 includes a screen 10 , a back cover 20 , a camera module 30 and a camera decoration 40 .

[0063] Understandably, Figure 1 and Figure 2 Only some components of the electronic device 100 are schematically shown, and the actual shapes, sizes, positions and structures of these components are not subject to the present invention. Figure 1 and Figure 2 In some other examples, the electronic device 100 may not include the screen 10, the camera module 30 and the camera decoration 40.

[0064] The screen 10 is used to display images, videos, etc. Specifically, the screen 10 can be an organic light-emitting diode (OLED) screen, an active-matrix organic light-emitting diode or an active-matrix organic light-emitting diode (AMOLED) screen, a mini light-emitting diode screen, a micro light-emitting diode screen, a micro organic light-emitting diode screen, a quantum dot light emitting diode (QLED) screen, or a liquid crystal display (LCD).

[0065] The back shell 20 forms the housing of the electronic device 100, and is connected to the screen 10. Specifically, the back shell 20 and the screen 10 may be connected by gluing. A receiving space is provided in the back shell 20, and the back shell 20 is used to protect the electronic devices in the receiving space.

[0066] In some embodiments, please refer to Figure 2 The back shell 20 may include a middle frame 21 and a back cover 22. The middle frame 21 is located between the screen 10 and the back cover 22. The screen 10 and the back cover 22 are both connected to the middle frame 21. The above-mentioned accommodation space is formed between the middle frame 21 and the back cover 22. This structure is simple and easy to assemble.

[0067] The camera module 30 is an electronic device of the electronic device, and the camera module 30 is accommodated in the above-mentioned accommodation space. Figure 2 The back cover 22 is provided with a mounting opening 50, and the camera decoration piece 40 covers and is fixed to the mounting opening 50. The camera decoration piece 40 is provided with a light-transmitting window 41, which faces the light-entering surface of the camera module 30, and allows external light to pass through and enter the camera module 30.

[0068] In the above embodiment, the back cover 22 forms the shell structure of the electronic device. When the electronic device 100 is of other structures, the shell structure may also be of other structures. For example, when the electronic device 100 is a tablet computer, the shell structure may be the back shell of the tablet computer. When the electronic device 100 is a notebook computer, the shell structure may be the A shell, B shell, C shell or D shell of the notebook computer. The following embodiments are exemplified by taking the shell structure of the electronic device 100 as the back cover 22, which cannot be regarded as a special limitation on the specific structural form of the shell structure.

[0069] On the basis of the above, it should be noted that the “outside” used in the following embodiments to describe the shell structure and the various parts within the shell structure refers to the side of the described object facing away from the internal storage space of the electronic device; the “outer surface” refers to the surface of the described object facing away from the internal storage space of the electronic device; the “inside” refers to the side of the described object facing the internal storage space of the electronic device, and the “inner surface” refers to the surface of the described object facing the internal storage space of the electronic device.

[0070] See also Figure 3 and Figure 4 , Figure 3 for Figure 2 The three-dimensional diagram of the housing structure of the electronic device 100 is shown. Figure 4 for Figure 3 The cross-sectional structure schematic diagram of the shell structure along line AA is shown. The shell structure includes a base 221 and a leather 222.

[0071] The base 221 is a hard structure, which is used to ensure the structural strength of the shell structure.

[0072] The substrate 221 may be in the form of a plate, a sheet, a block, etc., and the present application is exemplified by the substrate 221 being in the form of a plate. Based on this, the substrate 221 may be in the form of a flat plate, or may include a flat plate portion in the middle and an arc-shaped plate portion disposed on at least one side of the flat plate portion. The present application is exemplified by the substrate 221 including a flat plate portion in the middle and arc-shaped plate portions disposed on opposite sides of the flat plate portion, which cannot be regarded as a special limitation on the substrate 221.

[0073] The material of the substrate 221 includes, but is not limited to, at least one of polycarbonate (PC), glass fiber, aramid fiber, polyethylene terephthalate (PET), ABS plastic (acrylonitrile butadiene styrene plastic), polyvinyl chloride (PVC), thermoplastic polyurethane elastomer (TPU) and polymethyl methacrylate (PMMA). Specifically, the material of the substrate 221 can be PC, a composite material of PC and glass fiber, ABS plastic, polymethyl methacrylate (PMMA) or a composite material of PC and PMMA, which is not specifically limited in the present application.

[0074] The leather 222 is disposed on the outer surface of the base 221 . Specifically, the leather 222 can be connected to the base 221 by adhesive.

[0075] The leather 222 may be genuine leather, recycled leather, artificial leather or synthetic leather. The artificial leather and synthetic leather may be made of polyurethane (PU) or polyvinyl chloride (PVC).

[0076] The surface of the leather 222 facing away from the substrate 221 has a texture. The texture described in this embodiment and the following embodiments refers to the lines formed by depressions or protrusions on the surface. The texture can be a checkered pattern, a grain pattern, a fine pattern, a scale pattern, a lace pattern, a carved pattern, and the like.

[0077] The leather 222 can improve the quality of the electronic device 100, and because the leather 222 is soft, it can improve the touch of the electronic device 100. However, since the leather 222 is expensive, the cost of the housing structure and even the electronic device 100 is high.

[0078] To solve the above problems, see Figure 5 and Figure 6 , Figure 5 This is a schematic cross-sectional view of a housing structure provided in some embodiments of the present application. Figure 6 for Figure 5 The exploded structural diagram of the housing structure is shown. In this embodiment, the housing structure includes a base 221 , a color layer 223 and a first light-transmitting texture layer 224 .

[0079] The structure of the substrate 221 may be the same as that of the substrate 221 described in any of the above embodiments, and this application will not elaborate on this. The material of the substrate 221 may also be the same as that of the substrate 221 described in any of the above embodiments, and this application uses PC as an example for explanation.

[0080] The substrate 221 can be a light-transmitting structure or a light-impermeable structure. In the embodiment of the present application, the light-transmitting structure refers to a structure with a light transmittance greater than or equal to 50%, and the light-impermeable structure refers to a structure with a light transmittance less than or equal to 10%. This embodiment and the following embodiments are exemplified by using the substrate 221 as a light-transmitting structure. When the substrate 221 is a light-transmitting structure, the substrate 221 blocks less light, and the shell structure can be designed with a richer appearance effect.

[0081] The color layer 223 is disposed on at least a portion of the outer surface of the substrate 221, that is, the color layer 223 can be disposed on a portion of the outer surface of the substrate 221, or can be disposed on the entire outer surface of the substrate 221. This application is exemplified by the color layer 223 being disposed on a portion of the outer surface of the substrate 221, so that the shell structure can be designed with a richer appearance effect.

[0082] The color layer 223 is used to provide the basic color of the imitation leather effect, and the color of the color layer 223 includes but is not limited to black, white, brown, yellow, green, red, purple, orange, etc. The color of the color layer 223 can be a single color, or a combination or gradient of multiple colors, so that the color layer 223 can enrich the color effect of the product.

[0083] In some embodiments, the color layer 223 can be directly disposed on the outer surface of the substrate 221, that is, the material of the color layer 223 is in direct contact with the material of the substrate 221. In other embodiments, a primer layer, a transition layer, or an adhesive layer can be disposed between the color layer 223 and the substrate 221, and this application does not specifically limit this.

[0084] The material of the color layer 223 includes, but is not limited to, ink. The color of the ink is better adjustable, and the desired color can be mixed. In addition, the ink is fine in texture, and when the color layer 223 is directly disposed on the outer surface of the substrate 221, it can be closely combined with the material of the substrate 221 to prevent the color layer 223 from falling off.

[0085] Please continue reading Figure 5 and Figure 6 The first light-transmitting texture layer 224 is disposed on the side of the color layer 223 facing away from the substrate 221, and the first light-transmitting texture layer 224 can cover at least part of the color layer 223, that is, the first light-transmitting texture layer 224 can cover a part of the color layer 223, or can cover the entire color layer 223. This embodiment is exemplified by the first light-transmitting texture layer 224 covering a part of the color layer 223.

[0086] The first light-transmitting texture layer 224 may be a light-transmitting structure, specifically, the first light-transmitting texture layer 224 may be a fully light-transmitting structure or a semi-light-transmitting structure, wherein the fully light-transmitting structure means that the light transmittance of the structure is greater than or equal to 90%, and the semi-light-transmitting structure means that the light transmittance of the structure is greater than or equal to 50% and less than 90%.

[0087] When the first light-transmitting texture layer 224 is a semi-light-transmitting structure, the first light-transmitting texture layer 224 can be made of a fully transparent material doped with pigment particles, metal particles, dust or other light-shielding materials.

[0088] The first light-transmitting texture layer 224 provides the appearance texture of the shell structure. Specifically, the surface of the first light-transmitting texture layer 224 facing the color layer 223 and / or the surface of the first light-transmitting texture layer 224 facing away from the color layer 223 is provided with a first texture (not shown in the figure), which is the same as the surface texture of leather.

[0089] According to the previous description, there are many types of surface textures of leather, such as plaid, grain, fine lines, scales, lace and carved patterns, etc. If the first texture is the same as any one of the various surface textures of the leather, it can be considered that the first texture is the same as the surface texture of the leather.

[0090] In this way, the color layer 223 provides the basic color of the imitation leather effect, and the first light-transmitting texture layer 224 provides the texture of the imitation leather effect, so as to form an appearance with the imitation leather effect, thereby improving the quality of the housing structure and the electronic device. At the same time, the base 221, the color layer 223 and the first light-transmitting texture layer 224 can be made of low-cost materials, thereby improving the quality of the housing structure and the electronic device while reducing the cost of the housing structure and the electronic device.

[0091] In some embodiments, the material of the substrate 221 can be selected as PC, which has a low cost and a strong bonding force between PC and ink. Therefore, when the material of the color layer 223 is ink, the bonding force between the color layer 223 and the substrate 221 can be enhanced to prevent the color layer 223 from falling off the substrate 221.

[0092] In some embodiments, the material of the first light-transmitting texture layer 224 can be selected to be an elastic soft material. The elastic soft material has elasticity and can produce a leather-like touch, thereby improving the touch of the housing structure and the electronic device 100.

[0093] Specifically, the material of the first light-transmitting texture layer 224 includes but is not limited to ultraviolet rays (UV) curing adhesive, pressure-sensitive adhesive, thermosetting adhesive or hot melt adhesive.

[0094] Optionally, the material of the first light-transmitting texture layer 224 can be selected to be UV curing glue, which does not pollute the ambient air and cures quickly under ultraviolet light, thus facilitating automated production.

[0095] Specifically, the material of the first light-transmitting texture layer 224 may include one or more of epoxy acrylate, polyurethane acrylate, polyether acrylate, polyester acrylate, and acrylic resin.

[0096] In some embodiments, the first light-transmitting texture layer 224 can be directly disposed on the surface of the color layer 223 facing away from the substrate 221, that is, the material of the first light-transmitting texture layer 224 is in direct contact with the material of the color layer 223. In this way, the shell structure is simple and the processing efficiency is high.

[0097] In other embodiments, an optical composite layer, a light-transmitting adhesive layer or a light-transmitting transition layer may also be disposed between the first light-transmitting texture layer 224 and the color layer 223 , and this application does not make any specific limitation on this.

[0098] In some embodiments, see Figure 5 and Figure 6 The color layer 223 may be disposed on a portion of the outer surface of the substrate 221. Specifically, the color layer 223 may be disposed on a continuous region of the outer surface of the substrate 221, or may be disposed on a plurality of discrete regions of the outer surface of the substrate 221. This embodiment is exemplified by arranging the color layer 223 on a continuous region of the outer surface of the substrate 221.

[0099] For details, please refer to Figure 5 and Figure 6 The outer surface of the substrate 221 includes a first region Q1 and a second region Q2 , and the color layer 223 is disposed in the first region Q1 but not in the second region Q2 .

[0100] In this way, the shell structure can form a leather-like appearance in the first area Q1 and other appearances in the second area Q2, so as to reduce the setting area of ​​the color layer 223 and the first light-transmitting texture layer 224, save costs, and form more diverse appearances.

[0101] Based on the above examples, please continue to refer to Figure 5 and Figure 6 An optical coating layer 225 is disposed on a side of the substrate 221 facing away from the color layer 223 , and at least a portion of the optical coating layer 225 is opposite to the second region Q2 .

[0102] In this way, the user can see the optical coating layer 225 through the substrate 221, and the second area Q2 can present the appearance of the optical coating layer 225, so that the shell structure can present the splicing appearance of imitation leather and the optical coating layer 225, so the appearance performance is better.

[0103] In some embodiments, please refer to Figure 5 and Figure 6 , the optical coating layer 225 may be partially opposite to the second area Q2, and the other part is opposite to the first area Q1. In other words, the projection of the optical coating layer 225 on the outer surface of the substrate 221 is partially located in the second area Q2, and the other part is located in the first area Q1. In this way, the difficulty of setting the optical coating layer 225 can be reduced, and the flatness of the inner surface of the housing structure can be improved.

[0104] On the basis of the above, optionally, the optical coating layer 225 can cover the entire outer surface of the substrate 221, that is, the projection of the optical coating layer 225 on the outer surface of the substrate 221 roughly coincides with the outer surface of the substrate 221. In this way, the flatness of the inner surface of the housing structure can be improved.

[0105] In other embodiments, the optical coating layer 225 may be entirely opposite to the second region Q2, that is, the projection of the optical coating layer 225 on the outer surface of the substrate 221 is located in the second region Q2, or overlaps with the second region Q2. In this way, the area where the optical coating layer 225 is disposed can be reduced, saving material costs.

[0106] The optical coating layer 225 may be a color layer with a reflective effect. In some embodiments, the optical coating layer 225 may be an indium tin alloy film layer, a silicon dioxide film layer, a titanium oxide film layer, or a zirconium oxide film layer.

[0107] In the above embodiment, the optical coating layer 225 can be directly disposed on the inner surface of the substrate 221, that is, the material of the optical coating layer 225 is in direct contact with the material of the substrate 221. In other embodiments, a texture layer, a transition layer or an adhesive layer can be further disposed between the optical coating layer 225 and the substrate 221, and this application does not specifically limit this.

[0108] In some embodiments, please refer to Figure 5 and Figure 6The shell structure further includes a second light-transmitting texture layer 226. The second light-transmitting texture layer 226 is disposed between the substrate 221 and the optical coating layer 225, and a second texture is provided on a surface of the second light-transmitting texture layer 226 facing the substrate 221 and / or a surface of the second light-transmitting texture layer 226 facing the optical coating layer 225. The second texture may be a flash sand texture. The second texture may also be a matte texture, which may be the same as the surface texture of frosted glass to form a matte effect. The second texture may also be a glare texture. The glare texture may be the same as the texture on the surface of the optical disc, or may be a laser texture to achieve a glare effect.

[0109] In this way, the second light-transmitting texture layer 226 and the optical coating layer 225 can provide rich visual effects and achieve diversified appearance effects of the shell structure.

[0110] In some embodiments, please refer to Figure 5 and Figure 6 The housing structure further includes a base layer 227, which is disposed on the side of the optical coating layer 225 facing away from the substrate 221. The base layer 227 is used to protect the optical coating layer 225, preventing the optical coating layer 225 from being scratched and affecting the appearance of the housing structure. At the same time, the base layer 227 is also used to absorb light, preventing the user from viewing the inner parts of the housing structure from the outer surface of the housing structure, thereby further improving the appearance of the housing structure.

[0111] In some embodiments, the material of the base layer 227 includes, but is not limited to, ink, plastic, foam, and silicone, etc. Optionally, the material of the base layer 227 is ink, which occupies less space and is conducive to thinning electronic devices, and the ink is easy to set, which is conducive to reducing the difficulty of production.

[0112] In some embodiments, the color of the base layer 227 may be a dark color, which refers to a color with a lightness (L value) less than 0. Specifically, the color of the base layer 227 includes but is not limited to black, dark gray, dark blue, coffee color, brown, and the like.

[0113] In this way, the base layer 227 has a better light absorption ability, which can effectively prevent the user from viewing the inner parts of the shell structure from the outer surface of the shell structure, thereby ensuring the appearance effect of the shell structure.

[0114] In some embodiments, the base layer 227 can be directly disposed on the optical coating layer 225, that is, the material of the base layer 227 is in direct contact with the material of the optical coating layer 225. In other embodiments, a transition layer or an adhesive layer can be further disposed between the base layer 227 and the optical coating layer 225, which is not specifically limited in the present application.

[0115] In some embodiments, please refer to Figure 5 and Figure 6 The shell structure may further include a third light-transmitting texture layer 228. At least a portion of the third light-transmitting texture layer 228 is disposed in the second region Q2. The surface of the third light-transmitting texture layer 228 facing away from the substrate 221 and / or the surface of the third light-transmitting texture layer 228 facing the substrate 221 is provided with a third texture.

[0116] In this way, the third light-transmitting texture layer 228 is combined with the base 221 , the second light-transmitting texture layer 226 , and the optical coating layer 225 to provide a richer visual effect.

[0117] The third texture may be a shiny sand texture, or a frosted texture or a glare texture. The present application uses the shiny sand texture as an example to illustrate the third texture.

[0118] The material of the third light-transmitting texture layer 228 includes, but is not limited to, UV curing adhesive, pressure-sensitive adhesive, thermosetting adhesive or hot melt adhesive.

[0119] In some embodiments, the material of the third light-transmitting texture layer 228 can be the same as that of the first light-transmitting texture layer 224. For example, both are UV glue, and the third light-transmitting texture layer 228 and the first light-transmitting texture layer 224 can be an integral structure. In this way, the shell structure is simple and the molding difficulty is low.

[0120] In the above embodiment, at least a portion of the third light-transmitting texture layer 228 is disposed in the second region Q2, which means that the third light-transmitting texture layer 228 can be disposed in the second region Q2 as a whole, or a portion of the third light-transmitting texture layer 228 can be disposed in the second region Q2, and the other portion can be disposed on the side of the color layer 223 facing away from the substrate 221.

[0121] In some embodiments, please refer to Figure 5 and Figure 7 , Figure 7 for Figure 5 A schematic diagram of the structure of the outer surface of the shell structure shown. A portion of the third light-transmitting texture layer 228 is disposed in the second region Q2, and another portion is disposed on the side of the color layer 223 that is away from the substrate 221. Figure 7 The boundary between the first region Q1 and the second region Q2 is the first boundary L1 (indicated by a dotted line), the boundary between the third light-transmitting texture layer 228 and the first light-transmitting texture layer 224 is the second boundary L2 (indicated by a solid line), and the projection of the second boundary L2 on the outer surface of the base 221 is located in the first region Q1. In this way, the first boundary L1 and the second boundary L2 can be prevented from intersecting and affecting the appearance of the shell structure.

[0122] In some embodiments, the distance between the second boundary line L2 and the first boundary line L1 may be less than or equal to 0.5 mm. Specifically, the distance between the second boundary line L2 and the first boundary line L1 may be 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm or 0.5 mm. In this way, the offset distance between the first boundary line L1 and the second boundary line L2 is moderate, which can prevent the first boundary line L1 and the second boundary line L2 from intersecting, thereby ensuring the appearance of the shell structure.

[0123] See also Figure 8 and Fig. 9 , Figure 8 This is a schematic cross-sectional view of a housing structure provided in some embodiments of the present application. Fig. 9 for Figure 8 The exploded structural diagram of the shell structure is shown. Figure 5 and Figure 6 In the shell structure shown in the embodiment, the color layer 223 is arranged on the entire area of ​​the outer surface of the substrate 221 , and the first light-transmitting texture layer 224 is arranged on the side of the color layer 223 facing away from the substrate 221 .

[0124] In this way, the entire outer surface of the housing structure presents an appearance of imitation leather, which can also improve the quality of the housing structure and the electronic device while reducing the cost of the housing structure and the electronic device.

[0125] On the basis of the above embodiment, the base layer 227 is disposed on the side of the base 221 facing away from the color layer 223. In some embodiments, the base layer 227 can be directly disposed on the surface of the base 221 facing away from the color layer 223, that is, the material of the base layer 227 is in direct contact with the material of the base 221. In this way, the shell structure is simple in structure, high in processing efficiency, and thin in thickness, which is conducive to the thinning of the shell structure and the electronic device.

[0126] In other embodiments, an intermediate layer, a primer layer, a transition layer or an adhesive layer may be provided between the base layer 227 and the substrate 221 , and this application does not make any specific limitation thereto.

[0127] See also Fig.10 , Fig.10 The schematic diagram of the cross-sectional structure of the housing structure provided by some other embodiments of the present application is as follows: In this embodiment, an optical composite layer 229 may be provided between the color layer 223 and the first light-transmitting texture layer 224 .

[0128] The optical composite layer 229 is a light-transmitting structure and is used to adjust the brightness (ie, L value) of the color layer 223 .

[0129] In this way, by using the optical composite layer 229, the brightness of the color of the color layer 223 can be adjusted, so that the imitation leather appearance of the shell structure does not depend on the color of the color layer 223, thereby increasing the color adjustability.

[0130] In some embodiments, the optical composite layer 229 may include first optical layers 229a and second optical layers 229b that are alternately and stacked in sequence, and the refractive index of the first optical layer 229a is greater than the refractive index of the second optical layer 229b. The structure of the optical composite layer 229 is simple and easy to implement.

[0131] The present application also provides a processing method, which is used to process the shell structure described in any of the above embodiments.

[0132] See also Fig.11 and Fig.12 , Fig.11 A flowchart of a method for processing a shell structure provided in some embodiments of the present application, Fig.12 for Fig.11 The structural diagram of the processing method of the shell structure shown in FIG. The processing method may include the following steps S10 to S30.

[0133] Step S10: Provide a substrate 221, the cross-sectional structure of the substrate 221 can be Fig.12 The structure shown in (a).

[0134] The substrate 221 may be a light-transmitting substrate. In other embodiments, the substrate 221 may also be a light-impermeable substrate.

[0135] The material of the substrate 221 includes but is not limited to at least one of PC, glass fiber, aramid fiber, PET, ABS plastic, PVC, TPU and PMMA. Specifically, the material of the substrate 221 can be PC, a composite material of PC and glass fiber, ABS plastic, PMMA or a composite material of PC and PMMA. This application is exemplified by taking PC as the material of the substrate 221.

[0136] The substrate 221 may be in a plate shape, a sheet shape, a block shape, etc., and the present application uses the substrate 221 in a plate shape as an example.

[0137] The substrate 221 has an outer surface M1 , which refers to a surface of the substrate 221 that faces away from an internal receiving space of the electronic device when the substrate 221 is applied to the electronic device.

[0138] Step S20: Please refer to Fig.12 In (b), a color layer 223 is provided on at least a portion of the outer surface M1 of the substrate 221 .

[0139] The material of the color layer 223 includes, but is not limited to, ink. The color layer 223 can be provided on the outer surface of the substrate 221 by printing, printing, spraying, silk-screening, or dipping. The color layer 223 can be provided on a part of the outer surface of the substrate 221, or on the entire outer surface of the substrate 221. This embodiment is exemplified by providing the color layer 223 on a part of the outer surface of the substrate 221.

[0140] Specifically, please continue to refer to the outer surface M1 of the substrate 221 including the first area Q1 and the second area Q2. Based on this, step S20 may specifically include: providing a color layer 223 in the first area Q1 of the outer surface M1 of the substrate 221. In this way, the color layer 223 is not provided in the second area Q2, which can reduce the area for providing the color layer 223 and save costs.

[0141] Step S30: Please refer to Fig.12 In (f), a first light-transmitting texture layer 224 is disposed on the side of the color layer 223 facing away from the substrate 221 .

[0142] The surface of the first light-transmitting texture layer 224 facing the color layer 223 and / or the surface of the first light-transmitting texture layer 224 facing away from the color layer 223 is provided with a first texture, and the first texture is the same as the surface texture of leather.

[0143] In this way, the color layer 223 provides the basic color of the imitation leather effect, and the first light-transmitting texture layer 224 provides the texture of the imitation leather effect, so as to form an appearance with the imitation leather effect, thereby improving the quality of the housing structure and the electronic device. At the same time, the base 221, the color layer 223 and the first light-transmitting texture layer 224 can be made of low-cost materials, thereby improving the quality of the housing structure and the electronic device while reducing the cost of the housing structure and the electronic device.

[0144] In the above embodiment, the first light-transmitting texture layer 224 can be disposed on the side of the color layer 223 facing away from the substrate 221 by using processes such as rubbing, transfer, bonding, and hot pressing, and the present application does not make any specific limitation on this.

[0145] The first light-transmitting texture layer 224 can be directly disposed on the surface of the color layer 223 facing away from the substrate 221, that is, the material of the first light-transmitting texture layer 224 is in direct contact with the material of the color layer 223. In this way, the shell structure is simple in structure and has high processing efficiency. In other embodiments, an optical composite layer, a light-transmitting adhesive layer or a light-transmitting transition layer can also be disposed between the first light-transmitting texture layer 224 and the color layer 223, and this application does not specifically limit this.

[0146] In some embodiments, please refer to Fig.11The processing method also includes the following steps S40 and S50.

[0147] Step S40: Please refer to Fig.12 In (c), a second light-transmitting texture layer 226 is disposed on a side of the substrate 221 facing away from the color layer 223, and at least a portion of the second light-transmitting texture layer 226 is opposite to the second region Q2.

[0148] The surface of the second light-transmitting texture layer 226 facing the substrate 221 and / or the surface of the second light-transmitting texture layer 226 facing away from the substrate 221 are provided with a second texture. The second texture may be a glittering sand texture, a matte texture or a glare texture. The glittering sand texture may be the same as the surface texture of glittering sand, and the matte texture may be the same as the surface texture of frosted glass to form a matte effect. The glare texture may be the same as the texture on the surface of the optical disc, or may be a laser texture to achieve a glare effect.

[0149] In some embodiments, the second light-transmitting texture layer 226 can be disposed on the side of the substrate 221 facing away from the color layer 223 by using processes such as rubbing, transfer, bonding, and hot pressing, and the present application does not make any specific limitation on this.

[0150] The second light-transmitting texture layer 226 may be entirely opposite to the second region Q2 or may be partially opposite to the second region Q2.

[0151] In some embodiments, see Fig.12 In (c), the second light-transmitting texture layer 226 can cover the entire outer surface of the substrate 221, that is, the projection of the second light-transmitting texture layer 226 on the outer surface of the substrate 221 roughly coincides with the outer surface of the substrate 221. In this way, processing is convenient and the flatness of the inner surface of the shell structure can be ensured.

[0152] Step S50: Please refer to Fig.12 In (d), an optical coating layer 225 is disposed on a side of the second light-transmitting texture layer 226 facing away from the substrate 221 , and at least a portion of the optical coating layer 225 is opposite to the second region Q2 .

[0153] The optical coating layer 225 may be entirely opposite to the second region Q2 or may be partially opposite to the second region Q2.

[0154] In some embodiments, the optical coating layer 225 may cover the entire outer surface of the substrate 221, that is, the projection of the optical coating layer 225 on the outer surface of the substrate 221 substantially coincides with the outer surface of the substrate 221. This facilitates processing and ensures the flatness of the inner surface of the housing structure.

[0155] Optionally, the optical coating layer 225 can be disposed on the side of the second light-transmitting texture layer 226 facing away from the substrate 221 by a physical vapor deposition (PVD) coating process. Specifically, the PVD coating process can use metal, metal oxide, or non-metal oxide as a target material to form the optical coating layer 225 by evaporation coating, magnetron sputtering coating, or ion plating.

[0156] Among them, metal targets include but are not limited to aluminum, titanium, zirconium, chromium, niobium, etc.; metal oxide targets include but are not limited to titanium dioxide, etc.; non-metal oxide targets include but are not limited to silicon dioxide, etc. In order to achieve the expected optical texture effect, those skilled in the art can choose a single target material for coating, or can choose two or more different target materials for coating, and this application does not make specific restrictions on this.

[0157] In this way, the second light-transmitting texture layer 226 and the optical coating layer 225 can provide rich visual effects and achieve diversified appearance effects of the shell structure.

[0158] In some embodiments, please refer to Fig.11 The processing method further includes the following step S60.

[0159] Step S60: Please refer to Fig.12 In (e), a base layer 227 is disposed on a side of the optical coating layer 225 that is opposite to the second light-transmitting texture layer 226 .

[0160] The base layer 227 is used to protect the optical coating layer 225, preventing the optical coating layer 225 from being scratched and affecting the appearance of the housing structure. At the same time, the base layer 227 is also used to absorb light to prevent the user from viewing the inner parts of the housing structure from the outer surface of the housing structure, thereby further improving the appearance of the housing structure.

[0161] In some embodiments, the material of the base layer 227 includes, but is not limited to, ink, plastic, foam, and silicone, etc. Optionally, the material of the base layer 227 is ink, which occupies less space and is conducive to the thinning of electronic devices.

[0162] In some embodiments, the base layer 227 can be disposed on the side of the optical coating layer 225 facing away from the second light-transmitting texture layer 226 by using processes such as printing, printing, spraying, silk-screening or dipping.

[0163] The above-mentioned steps S40, S50 and S60 may be executed before step S20, or after step S20 and before step S30, or after step S30. The present application is exemplified by the above-mentioned steps S40, S50 and S60 being executed after step S20 and before step S30, which cannot be regarded as a special limitation to the present application.

[0164] In some embodiments, please refer to Fig.11 , the processing method also includes the following step S70.

[0165] Step S70: Please refer to Fig.12 In (f), the third light-transmitting texture layer 228 is provided at least in the second region Q2. That is, the third light-transmitting texture layer 228 may be provided only in the second region Q2, or in addition to the third light-transmitting texture layer 228 being provided in the second region Q2, the third light-transmitting texture layer 228 may also be provided in other locations (such as the surface of the color layer 223 facing away from the substrate 221). In some embodiments, see Fig.12 In (f), a portion of the third light-transmitting texture layer 228 is disposed in the second region Q2, and another portion is disposed on the surface of the color layer 223 facing away from the substrate 221. The boundary line between the third light-transmitting texture layer 228 and the first light-transmitting texture layer 224 is the second boundary line L2, and the boundary line between the first region Q1 and the second region Q2 is the first boundary line L1. In this way, the projection of the second boundary line L2 on the outer surface of the substrate 221 is located within the first region Q1 to prevent the first boundary line L1 and the second boundary line L2 from intersecting and affecting the appearance of the shell structure.

[0166] The surface of the third light-transmitting texture layer 228 facing away from the substrate 221 and / or the surface of the third light-transmitting texture layer 228 facing the substrate 221 is provided with a third texture. The third texture may be a glittering sand texture, a frosted texture or a glare texture.

[0167] In this way, the third light-transmitting texture layer 228 is combined with the base 221 , the second light-transmitting texture layer 226 , and the optical coating layer 225 to provide a richer visual effect.

[0168] Specifically, the third light-transmitting texture layer 228 can be disposed in the second region Q2 by using processes such as rubbing, transfer, bonding, and hot pressing, and the present application does not make any specific limitation on this.

[0169] Step S70 may be executed simultaneously with step S30, or may be executed after step S30, or may be executed before step S30. This application exemplifies the execution of step S70 and step S30 simultaneously.

[0170] In some embodiments, the material of the third light-transmitting texture layer 228 can be the same as that of the first light-transmitting texture layer 224. For example, both can be UV glue, and the third light-transmitting texture layer 228 and the first light-transmitting texture layer 224 can be an integral structure. In this way, the shell structure is simple and the molding difficulty is low.

[0171] In some embodiments, see Fig.11 Before step S30, the processing method may further include the following step S80.

[0172] Step S80 : setting a trademark (LOGO) on the side of the color layer 223 facing away from the substrate 221 .

[0173] Specifically, the material of the trademark includes but is not limited to ink. The trademark can be set on the side of the color layer 223 facing away from the substrate 221 by silk screen printing, printing, spraying or dipping.

[0174] Based on the above, step S30 may include: arranging a first light-transmitting texture layer 224 on the side of the color layer 223 facing away from the substrate 221, and covering the trademark with the first light-transmitting texture layer 224. In this way, the trademark can be protected by the first light-transmitting texture layer 224 to prevent the trademark from being worn.

[0175] In other embodiments, before step S70, the processing method may further include the following step S80.

[0176] Step S80: Setting a logo in the second area Q2.

[0177] Based on the above, step S70 may include: arranging a third light-transmitting texture layer 228 in the second region Q2, and making the third light-transmitting texture layer 228 cover the trademark. In this way, the trademark can be protected by the third optical texture layer 228 to prevent the trademark from being worn.

[0178] Step S80 described in any of the above embodiments may be executed after step S20 and before step S40, or may be executed after step S20 and before step S30 and step S70. This application is exemplified by the execution of step S80 after step S20 and before step S40, which cannot be regarded as a special limitation on the present application.

[0179] According to the above steps S10 to S80, a housing module can be obtained, which includes a substrate 221, a color layer 223, a first light-transmitting texture layer 224, an optical coating layer 225, a second light-transmitting texture layer 226, a base layer 227 and a third light-transmitting texture layer 228. Based on this, the processing method also includes the following steps S90 and S100.

[0180] Step S90: bending two opposite edge portions of the housing module to form a 3D housing structure, thereby improving the appearance refinement of the housing structure.

[0181] Specifically, the two opposite edge portions of the housing module may be bent by a hot bending process. The hot bending process is simple and has a high molding yield.

[0182] Step S100: Setting a mounting opening 50 on the housing module and removing the redundant edge portion of the housing module, wherein the mounting opening 50 is used to mount the camera decoration 40 .

[0183] In some embodiments, the above step S100 may be performed by using a computer numerical control (CNC) machine tool. The CNC processing technology is mature and has high precision, and can improve the molding yield of the substrate.
