Abstract
Description
Technical Field
[0001] The embodiments of the present application relate to the technical field of electronic devices, and in particular to a housing and an electronic device. Background Art
[0002] In electronic devices like mobile phones, the housing is a key feature that attracts consumers. Manufacturers primarily differentiate the housing's appearance through texture, material, and color. For non-metallic housings, the surface can be painted or silk-screened to create a specific look. However, the paint layer on the housing offers limited options for creating customizable effects, leading to a convergence of similar or monotonous appearances. Utility Model Content
[0003] The embodiments of the present application provide a housing and an electronic device, which solve the problem that the appearance effects of housings in related technologies are similar or single.
[0004] The embodiments of this application adopt the following technical solutions:
[0005] In a first aspect, embodiments of the present application provide a housing comprising: a material layer, a fiber texture layer, and a first paint layer. The fiber texture layer has a randomly distributed fiber texture and is impregnated with a transparent resin layer. The fiber texture layer impregnated with the transparent resin layer has a first surface and a second surface that are opposite to each other. The material layer is connected to the first surface, and the first paint layer is connected to the second surface. The first paint layer and / or the material layer are light-transmitting layers.
[0006] The shell provided in the embodiment of the present application has a fiber texture layer with randomly distributed fiber textures. The fiber texture layer is impregnated with a transparent resin layer. The transparent resin layer before curing is sticky, which facilitates the connection of the two opposite surfaces of the fiber texture layer with the material layer and the first paint layer, respectively, thereby improving the bonding strength between the fiber texture layer and the material layer, and between the fiber texture layer and the first paint layer. In the case where the first paint layer serves as the exterior surface of the shell, the first paint layer is a light-transmitting layer, and the texture of the fiber texture layer itself can be directly displayed as an exterior effect. The user can see the self-textured effect of the fiber texture layer through the first paint layer. In the case where the material layer serves as the exterior surface of the shell, the material layer is a light-transmitting layer, and the texture of the fiber texture layer itself can be directly displayed as an exterior effect. The user can see the self-textured effect of the fiber texture layer through the material layer. The fiber texture of the fiber texture layer is random, and the exterior textures of the shells of the same series of electronic devices are different. There are slight differences in the exterior textures of each shell, which makes each shell form a unique appearance and enhances its continued appeal to consumers.
[0007] In one optional implementation, the fiber texture layer may include at least one of a polyimide fiber paper layer, an aramid fiber paper layer, a flax fiber paper layer, and a silk fiber layer. The fiber texture layer has a randomly distributed fiber texture, resulting in a unique appearance for each housing, imbuing the housing with the texture of authentic materials and enhancing its natural aesthetic and designability.
[0008] In an optional implementation, the fiber texture layer may be formed by mixing multiple fibers, for example, a mixture of polyimide fiber and aramid fiber.
[0009] In an optional implementation, the fiber texture layer may include multiple regions, and the multiple regions may respectively use at least two of the following: a polyimide fiber paper layer, an aramid fiber paper layer, a flax fiber paper layer, and a silk fiber layer.
[0010] In an optional implementation, the thickness of the fiber texture layer ranges from 0.01 mm to 5 mm. Limiting the thickness of the fiber texture layer to the above range can make the shell thickness smaller and provide randomly distributed fiber textures.
[0011] In one optional implementation, the fiber texture layer includes at least one of long fibers and short fibers. The fiber texture layer can be made of either long fibers or short fibers, or a mixture of long fibers and short fibers. A variety of fiber texture layers with randomly distributed fiber textures are provided.
[0012] In one optional implementation, the transparent resin layer may include at least one of a polyurethane layer, an epoxy resin layer, and a UV-curable adhesive layer. The transparent resin layer is impregnated into the fiber texture layer, facilitating connection between the fiber texture layer impregnated with the transparent resin layer and the material layer and the first paint layer. This improves the bonding strength between the fiber texture layer and the material layer, and between the fiber texture layer and the first paint layer, ensuring a reliable connection between the different layers.
[0013] In an optional implementation, a silane coupling agent may be added to the transparent resin layer, or the transparent resin layer may be modified to increase active groups, including at least one of hydroxyl, carboxyl, ester, ketone, and amide groups, to enhance the bonding strength between the transparent resin layer and adjacent layers.
[0014] In an optional implementation, the fiber texture layer may not include a transparent resin impregnation layer, and the connection between the material layer and the fiber texture layer is achieved by the resin of the material layer infiltrating into the fiber texture layer.
[0015] In one optional implementation, the fiber texture layer can be natural or dyed. When the fiber texture layer is natural, no dyeing is required. When the fiber texture layer is dyed, a color layer is provided on the surface of the fiber texture layer, allowing the housing to have a variety of colors for users to choose from.
[0016] In an optional implementation, the material layer may include at least one of a metal layer, a fiber composite layer, a plastic layer, and a glass layer. Material layers made of different materials can all be reliably connected to the fiber texture layer.
[0017] In an optional implementation, the thickness of the material layer ranges from 0.01 mm to 5 mm. Limiting the material layer to the above range can reduce the thickness of the shell and provide a certain structural strength, with certain compression resistance, bending resistance, and shear resistance capabilities.
[0018] In an optional implementation, the material of the first paint layer may be resin, such as polyurethane, epoxy resin, or UV-curable adhesive.
[0019] In an optional implementation, the thickness of the first paint layer ranges from 0.01 mm to 1 mm. Limiting the first paint layer to the above range can reduce the thickness of the shell and provide a certain structural strength.
[0020] In one optional implementation, the material layer and the fiber texture layer are integrally hot-pressed. The material layer and the fiber texture layer impregnated with a transparent resin layer are stacked. The uncured transparent resin layer is viscous. The stack of fiber texture and material layers is then placed in a hot-pressing mold and heated and pressurized to cure the transparent resin layer on the fiber texture layer, ensuring a reliable connection between the fiber texture and material layers. This simple process.
[0021] In one optional implementation, the material layer and the fiber texture layer are connected via an adhesive layer. The adhesive layer is used to affix the fiber texture layer to the surface of the material layer, providing a secure connection and ease of operation. The adhesive layer can be made of hot melt adhesive, thermosetting adhesive, or the like.
[0022] In an optional implementation, the thickness of the adhesive layer may be in the range of 0.01 mm to 1 mm, so that the shell thickness is small and the material layer and the fiber texture layer are reliably connected.
[0023] In an optional implementation, after the material layer and the fiber texture layer are combined using one of the above methods, they can be milled and finished on a CNC machine tool to obtain a shaped plate of a predetermined shape. A first paint layer can be provided on the shaped plate (the second surface of the fiber texture layer).
[0024] In one optional implementation, where the first paint layer serves as the exterior surface of the housing, a fiber texture layer is applied to the outer surface of the base material layer, allowing the inherent texture of the fiber texture layer to be displayed through the first paint layer. The base material layer and the fiber texture layer can be integrally formed by hot pressing or bonding. A protective ink or paint can be sprayed or silk-screened on the second surface of the fiber texture layer to form the first paint layer, enhancing surface wear resistance and reliability.
[0025] In one optional implementation, when the first paint layer serves as the exterior surface of the housing, the transparency of the first paint layer is greater than or equal to 50%. External light can pass through the first paint layer, and reflected light formed on the fiber texture layer can be transmitted outward through the first paint layer, so that the texture of the fiber texture layer itself can be directly displayed as an exterior effect.
[0026] In an optional implementation, the transparency of the first paint layer is greater than or equal to 85%, so that light can better pass through the first paint layer, thereby allowing the texture of the fiber texture layer to better appear outward.
[0027] In one optional implementation, where the first paint layer serves as the exterior surface of the housing, a second paint layer is provided between the material layer and the fiber texture layer. This second paint layer can enhance the bonding between the material layer and the fiber texture layer and can also be used to conceal defects such as pits in the material layer. The second paint layer can be made of a resin, such as polyurethane, epoxy resin, or UV-curable adhesive.
[0028] In one optional implementation, when the material layer serves as the exterior surface of the housing, the material layer is a light-transmitting layer. The material of the light-transmitting layer can be glass, composite sheet material, transparent fiber composite sheet material, etc. A fiber texture layer is provided on the inner surface of the material layer, and the texture of the fiber texture layer is displayed through the material layer. The fiber texture layer can be protected by the material layer, providing higher reliability.
[0029] In an optional implementation, a light-transmitting protective layer is provided on the outer surface of the material layer. The outer surface of the material layer is the side of the material layer facing away from the fiber texture layer. The light-transmitting protective layer protects the material layer.
[0030] In one optional implementation, when the material layer serves as the exterior surface of the shell, the material layer has a transparency of 50% or greater. External light can pass through the material layer, and reflected light formed on the fiber texture layer can propagate outward through the material layer, allowing the texture of the fiber texture layer to be directly displayed as an exterior effect.
[0031] In an optional implementation, the transparency of the material layer is greater than or equal to 85%, so that light can better penetrate the material layer, thereby allowing the texture of the fiber texture layer to be better presented to the outside.
[0032] In one optional implementation, where the first paint layer serves as the exterior surface of the housing, a transparent brightening layer is provided between the first paint layer and the fiber texture layer. The transparent brightening layer is applied to the entire second surface of the fiber texture layer. The inherent texture of the fiber texture layer combined with the transparent brightening layer can highlight the texture and gloss of the fiber texture layer, enhancing the layered appearance of the housing.
[0033] In one optional implementation, where the first paint layer serves as the exterior surface of the housing, a transparent brightening layer is provided between the first paint layer and the fiber texture layer. The transparent brightening layer is applied to the entire second surface of the fiber texture layer. The fiber texture layer's inherent texture, combined with the transparent brightening layer, highlights the texture and gloss of the fiber texture layer, enhancing the layered appearance of the housing and facilitating molding. A second paint layer is provided between the material layer and the fiber texture layer. This second paint layer strengthens the bonding between the material layer and the fiber texture layer and can be used to conceal defects such as pits in the material layer.
[0034] In one optional implementation, when the material layer serves as the exterior surface of the housing, a transparent brightening layer is provided between the material layer and the fiber texture layer. The transparent brightening layer is applied to the entire first surface of the fiber texture layer. The inherent texture of the fiber texture layer combined with the transparent brightening layer can highlight the texture and gloss of the fiber texture layer, enhancing the layered appearance of the housing.
[0035] In one optional implementation, where the first paint layer or material layer serves as the exterior surface of the housing, a transparent brightening layer is applied to the outer surface of the fibers in the fiber texture layer. The transparent brightening layer is first applied to the outer surface of the fibers, and then the fibers with the transparent brightening layer are formed into the fiber texture layer. The inherent texture of the fiber texture layer, combined with the transparent brightening layer on the outer surface of the fibers, enhances the texture and gloss of the fiber texture layer, enhancing the layered appearance of the housing.
[0036] In an optional implementation, the transparent brightening layer may include at least one of an optical coating, a non-conductive vacuum plating film, and a pearlescent powder layer.
[0037] In an optional implementation, the thickness of the transparent brightening layer may range from 1 nanometer to 1 millimeter, which can effectively enhance the glossiness of the fiber texture layer and improve the appearance of the shell.
[0038] In a second aspect, embodiments of the present application provide an electronic device including a housing. The first paint layer may be a light-transmitting layer, serving as the exterior surface of the housing. The user may see through the first paint layer the natural texture of the fiber texture layer. Alternatively, the material layer may be a light-transmitting layer, serving as the exterior surface of the housing. The user may see through the material layer the natural texture of the fiber texture layer.
[0039] In an optional implementation, an electronic device includes a display screen, a back shell, and a middle frame. The display screen and the back shell are respectively disposed on opposite sides of the middle frame. At least one of the back shell and the middle frame may adopt the housing solution of the above embodiment.
[0040] In one optional implementation, the housing may include a flat panel portion and a frame portion, with the frame portion connected to an edge of the flat panel portion. The frame portion extends toward the same side as the edge of the flat panel portion. When the housing is used in an electronic device such as a mobile phone or tablet computer, the housing may serve as a back shell, with the flat panel portion and the midframe of the housing positioned opposite each other, and the frame portion connected to the midframe.
[0041] In an optional implementation, the shell may include a flat portion. When the shell is applied to electronic devices such as mobile phones and tablets, the shell can serve as a back shell, and the flat portion and the middle frame of the shell are arranged opposite to each other and connected to each other.
[0042] In one optional implementation, the flat portion has a boss portion, which has a mounting hole for mounting a camera module. This facilitates placement of a camera module of a certain size in the mounting hole of the boss portion, reduces the thickness of the housing outside the boss portion, and reduces the space occupied by the electronic device.

[0057] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application clearer, the application is further described in detail below in conjunction with the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application. Although the description of this application will be introduced in conjunction with some embodiments, this does not mean that the features of this application are limited to this embodiment. On the contrary, the purpose of introducing the application in conjunction with the embodiment is to cover other options or modifications that may be extended based on the claims of this application. In order to provide an in-depth understanding of the application, the following description will contain many specific details. This application can also be implemented without using these details. In addition, in order to avoid confusion or blurring the focus of this application, some specific details will be omitted in the description. It should be noted that the embodiments in this application and the features in the embodiments can be combined with each other unless there is a conflict.
[0058] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.
[0059] It should be understood that in the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. The orientation or positional relationship indicated by the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.
[0060] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.
[0061] In the embodiments of this application, "and / or" is simply a description of the association relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this document generally indicates that the related objects are in an "or" relationship.
[0062] References to "one embodiment" or "some embodiments" in this specification mean that a particular feature, structure, or characteristic described in conjunction with that embodiment is included in one or more embodiments of the present application. Thus, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," and "in yet other embodiments" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more but not all embodiments," unless otherwise specifically emphasized. The terms "including," "comprising," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.
[0063] See also Figure 1 A housing 10 in the related art includes a material layer 11, a primer layer 12, a color paint layer 13, and a light-transmitting protective layer 14, which are stacked in sequence. The primer layer 12 and the color paint layer 13 are formed using a conventional spray coating process. This housing 10 has a single color layer, a heavy plastic feel, and a mediocre texture, resulting in a uniform appearance.
[0064] See also Figure 2 , another shell 20 in the related art includes a material layer 21, a treatment agent layer 22, a color paint layer 23, an inner texture layer 24, a transparent brightening layer 25, a middle paint layer 26 and an outer texture layer 27 stacked in sequence. The inner texture layer 24 and the outer texture layer 27 can be ultraviolet light curing glue. The shell 20 is configured with one or more texture layers (24, 27) and a transparent brightening layer 25. Through multiple reflections and refractions of light between the middle paint layer 26 and the transparent brightening layer 25, the shell 20 can present a colorful, gradient or textured appearance. The appearance textures of the various shells 20 of the same series of electronic devices are consistent and not unique. Moreover, the provision of texture layers (24, 27) and transparent brightening layers 25 will increase the number of layers and interface bonding layers of the stacked structure, thereby increasing the risk of delamination of the shell 20 and having poor reliability.
[0065] See Figures 3 to 6 The present invention provides a housing 100 comprising a material layer 110, a fiber texture layer 120, and a first paint layer 130. The fiber texture layer 120 has randomly distributed fiber textures and is impregnated with a transparent resin layer. The fiber texture layer 120 impregnated with the transparent resin layer has a first surface 120a and a second surface 120b that are opposite to each other. The material layer 110 is connected to the first surface 120a, and the first paint layer 130 is connected to the second surface 120b. The first paint layer 130 and / or the material layer 110 are light-transmitting layers.
[0066] The fiber texture layer 120 has randomly distributed fiber textures, where fibers are irregularly distributed and can appear at any position. The fiber texture layer 120 is impregnated with a transparent resin layer. The transparent resin can coat the outer surface of the fiber texture layer 120 and can penetrate into the gaps between the fiber textures.
[0067] The first surface 120a of the fiber texture layer 120 and the material layer 110 can be directly connected, or another layer can be provided between them to achieve indirect connection. The second surface 120b of the fiber texture layer 120 and the first paint layer 130 can be directly connected, or another layer can be provided between them to achieve indirect connection.
[0068] The housing 100 provided in the embodiment of the present application has a fiber texture layer 120 with randomly distributed fiber textures. The fiber texture layer 120 is impregnated with a transparent resin layer. The transparent resin layer before curing is sticky, which facilitates the connection of the two opposite surfaces of the fiber texture layer 120 with the material layer 110 and the first paint layer 130, respectively, thereby improving the bonding strength between the fiber texture layer 120 and the material layer 110, and between the fiber texture layer 120 and the first paint layer 130. Figure 3 、 Figure 4 In the case where the first paint layer 130 serves as the exterior surface 100a of the housing 100, the first paint layer 130 is a light-transmitting layer, and the inherent texture of the fiber texture layer 120 can be directly displayed as an exterior effect. Users can see the inherent texture effect of the fiber texture layer 120 through the first paint layer 130. Figure 5 、 Figure 6 In the case where the material layer 110 serves as the exterior surface 100a of the housing 100, the material layer 110 is a light-transmitting layer. The inherent texture of the fiber texture layer 120 can be directly displayed as an exterior effect, allowing the user to see the inherent texture of the fiber texture layer 120 through the material layer 110. The fiber texture of the fiber texture layer 120 is random, resulting in different exterior textures between the housings 100 of the same electronic device series. Each housing 100 exhibits slight variations in exterior texture, giving each housing 100 a unique appearance and enhancing its continued appeal to consumers.
[0069] When setting the material of the fiber texture layer 120, refer to Figures 3 to 6 The fiber texture layer 120 can include at least one of a polyimide fiber paper layer, an aramid fiber paper layer, a flax fiber paper layer, and a silk fiber layer. The fiber texture layer 120 has a randomly distributed fiber texture, creating a unique appearance for each housing 100 and giving the housing 100 a sense of authentic material, enhancing the natural beauty and designability of the housing 100. The specific material of the fiber texture layer 120 can be customized as needed.
[0070] Polyimide (PI), also known as aromatic imide fiber, refers to fibers containing aromatic imide in their molecular chains. It exhibits high strength, high modulus, high-temperature resistance, chemical stability, radiation resistance, and strong insulation properties. Polyimide fiber can be made into polyimide fiber paper.
[0071] Aramid fiber generally refers to aromatic amide fiber, a synthetic fiber made from aromatic raw materials through polycondensation spinning. It has the characteristics of high strength, high modulus, high temperature resistance, chemical stability, strong insulation, and long service life. Aramid fiber can be made into aramid fiber paper.
[0072] Flax fiber is a natural fiber that has the characteristics of heat dissipation, fast moisture absorption and release, and breathability. Flax fiber can be made into flax fiber paper.
[0073] Silk fibers are formed from the mucus secreted by silkworms. They are brightly colored, highly absorbent, and breathable. Silk fibers can be made into silk fiber layers.
[0074] In some embodiments, the fiber texture layer 120 may be formed by mixing multiple types of fibers, for example, a mixture of polyimide fibers and aramid fibers.
[0075] In other embodiments, the fiber texture layer 120 may include multiple regions, and the multiple regions may respectively use at least two of the following: a polyimide fiber paper layer, an aramid fiber paper layer, a flax fiber paper layer, and a silk fiber layer.
[0076] When setting the thickness of the fiber texture layer 120, refer to Figures 3 to 6 The thickness of the fiber texture layer 120 is in the range of 0.01 mm to 5 mm. By limiting the thickness of the fiber texture layer 120 to the above range, the shell 100 can be made thinner and a randomly distributed fiber texture can be provided.
[0077] For example, the thickness of the fiber texture layer 120 ranges from 0.01 mm to 2 mm, which can make the shell 100 thinner and provide randomly distributed fiber textures.
[0078] For example, the thickness of the fiber texture layer 120 can be 0.01 mm, 0.02 mm, 0.05 mm, 0.1 mm, 0.2 mm, 0.5 mm, 0.8 mm, 1 mm, 2 mm, or 5 mm. The specific size of the fiber texture layer 120 can be set as needed.
[0079] When manufacturing the fiber texture layer 120, the fiber texture layer 120 includes at least one of long fibers and short fibers. Long fibers are fibers with a length of 5 mm or longer. Short fibers are fibers with a length between 1 mm and 5 mm. The fiber texture layer 120 can be made using either long fibers or short fibers, or a mixture of long fibers and short fibers. This provides a variety of fiber texture layers 120 with randomly distributed fiber textures.
[0080] The manufacturing process of the fiber texture layer 120 in this embodiment can be similar to the manufacturing process of paper, which requires adding and retaining predetermined fiber materials so that the finished fiber texture layer 120 has randomly distributed fiber textures.
[0081] When setting the transparent resin layer, refer to Figures 3 to 6 The transparent resin layer can include at least one of a polyurethane (PU) layer, an epoxy resin layer, and an ultraviolet (UV) light-curable adhesive layer. Impregnating the fiber texture layer 120 with the transparent resin layer facilitates bonding between the fiber texture layer 120, the material layer 110, and the first paint layer 130. This improves the bonding strength between the fiber texture layer 120 and the material layer 110, and between the fiber texture layer 120 and the first paint layer 130, ensuring a reliable connection between the different layers.
[0082] In order to enhance the bonding strength between the transparent resin layer and the adjacent layers, in some embodiments, a silane coupling agent may be added to the transparent resin layer, or the transparent resin layer may be modified to increase active groups, including at least one of hydroxyl, carboxyl, ester, ketone, and amide groups.
[0083] In other embodiments, the fiber texture layer 120 may not include a transparent resin impregnation layer, and the connection between the material layer 110 and the fiber texture layer 120 is achieved by the resin of the material layer 110 penetrating into the fiber texture layer 120 .
[0084] When setting the color of the fiber texture layer 120, the fiber texture layer 120 can be natural or dyed. When the fiber texture layer 120 is natural, no dyeing is required. When the fiber texture layer 120 is dyed, a color layer is provided on the surface of the fiber texture layer 120. The color layer can be black, white, gray, red, green, blue, or other colors, allowing the housing 100 to have a variety of colors for the user to choose from.
[0085] When setting the material of the material layer 110, refer to Figures 3 to 6 The material layer 110 may include at least one of a metal layer, a fiber composite layer, a plastic layer, and a glass layer. Material layers 110 made of different materials can all be reliably connected to the fiber texture layer 120.
[0086] The material of the metal layer can be aluminum alloy, magnesium alloy, stainless steel, titanium alloy, etc.
[0087] The fiber composite layer can be made of glass fiber and resin composites, carbon fiber and resin composites, and other materials. Fiber is added to the molten resin, distributing the fibers throughout the resin. After the resin solidifies, the resin and fibers bond. The fiber composite layer can be injection molded, offering high molding efficiency.
[0088] The material of the plastic layer can be polycarbonate (PC), polymethyl methacrylate (PMMA), etc.
[0089] The material of the glass layer can be quartz glass, silicate glass, etc.
[0090] When setting the thickness of the material layer 110, refer to Figures 3 to 6 The thickness of the material layer 110 is in the range of 0.01 mm to 5 mm. Limiting the material layer 110 to the above range can reduce the thickness of the housing 100 and provide a certain structural strength, with a certain degree of compression resistance, bending resistance, and shear resistance.
[0091] Exemplarily, the thickness of the material layer 110 ranges from 0.1 mm to 2 mm, which makes the shell 100 thinner and provides a certain structural strength with good compression resistance, bending resistance, and shear resistance.
[0092] For example, the thickness of the material layer 110 can be 0.01 mm, 0.02 mm, 0.05 mm, 0.1 mm, 0.2 mm, 0.5 mm, 0.8 mm, 1 mm, 2 mm, or 5 mm. The specific size of the material layer 110 can be set as needed.
[0093] When the first paint layer 130 is provided, the material of the first paint layer 130 may be resin, such as polyurethane, epoxy resin, or ultraviolet curing adhesive.
[0094] When setting the thickness of the first paint layer 130, refer to Figures 3 to 6 The thickness of the first paint layer 130 is in the range of 0.01 mm to 1 mm. By limiting the first paint layer 130 to the above range, the thickness of the housing 100 can be reduced and a certain structural strength can be provided.
[0095] For example, the thickness of the first paint layer 130 can be 0.01 mm, 0.03 mm, 0.05 mm, 0.1 mm, 0.2 mm, 0.3 mm, 0.5 mm, or 1 mm. The specific size of the first paint layer 130 can be set as needed.
[0096] There are multiple optional implementations for combining the material layer 110 and the fiber texture layer 120. The following is an exemplary implementation of connecting two material layers 110 and the fiber texture layer 120.
[0097] The first method of implementing the composite of the material layer 110 and the fiber texture layer 120 is as follows: Figure 3 、 Figure 5 The material layer 110 and the fiber texture layer 120 are an integrated hot-pressed structure.
[0098] The material layer 110 and the fiber texture layer 120 impregnated with a transparent resin layer are stacked. The uncured transparent resin layer is viscous. The stack of fiber texture layer 120 and material layer 110 is then placed in a hot press mold and heated and pressurized to cure the transparent resin layer on the fiber texture layer 120, thereby ensuring a reliable connection between the fiber texture layer 120 and the material layer 110. This process is simple. The heating temperature of the hot press mold can be above 80 degrees Celsius (°C), and the pressing pressure can be above 0.5 megapascals (MPa).
[0099] The second method of implementing the composite of the material layer 110 and the fiber texture layer 120 is as follows: Figure 4 、 Figure 6 The material layer 110 and the fiber texture layer 120 are connected by an adhesive layer 140 .
[0100] The fiber texture layer 120 is attached to the surface of the material layer 110 by using the adhesive layer 140, so that the material layer 110 and the fiber texture layer 120 are reliably connected and easy to operate. The adhesive layer 140 can be hot melt adhesive, thermosetting adhesive, etc.
[0101] The thickness of the adhesive layer 140 may be in a range of 0.01 mm to 1 mm, so that the thickness of the shell 100 is relatively small and the material layer 110 and the fiber texture layer 120 are reliably connected.
[0102] After the material layer 110 and the fiber texture layer 120 are combined using one of the above methods, they can be milled and finished on a computer numerical control (CNC) machine tool to obtain a shaped plate of a predetermined shape. Then, a first paint layer 130 can be applied to the shaped plate (the second surface 120b of the fiber texture layer 120).
[0103] In some embodiments, see Figure 3 、 Figure 4While the first paint layer 130 serves as the exterior surface 100a of the housing 100, the fiber texture layer 120 is applied to the outer surface of the material layer 110, allowing the texture of the fiber texture layer 120 to be displayed through the first paint layer 130. The material layer 110 and the fiber texture layer 120 can be integrally formed by hot pressing or bonding. A protective ink or paint can be sprayed or silk-screened on the second surface 120b of the fiber texture layer 120 to form the first paint layer 130, improving surface wear resistance and reliability.
[0104] In some embodiments, when the first paint layer 130 serves as the exterior surface 100a of the housing 100, the transparency of the first paint layer 130 is greater than or equal to 50%. External light can pass through the first paint layer 130, and light reflected from the fiber texture layer 120 can propagate outward through the first paint layer 130, allowing the texture of the fiber texture layer 120 to be directly displayed as an exterior effect.
[0105] For example, the transparency of the first paint layer 130 is greater than or equal to 85%, so that light can easily pass through the first paint layer 130 , thereby allowing the texture of the fiber texture layer 120 to be better presented to the outside.
[0106] In some embodiments, see Figure 7 When the first paint layer 130 serves as the exterior surface 100a of the housing 100, a second paint layer 150 is provided between the material layer 110 and the fiber texture layer 120. The second paint layer 150 can enhance the bonding strength between the material layer 110 and the fiber texture layer 120 and can also be used to conceal defects such as pits in the material layer 110. The second paint layer 150 can be made of a resin, such as polyurethane, epoxy resin, or UV-curable adhesive.
[0107] In some embodiments, see Figure 5 、 Figure 6 When the material layer 110 serves as the exterior surface 100a of the housing 100, the material layer 110 is a light-transmitting layer made of glass, composite material, transparent fiber composite material, etc. The fiber texture layer 120 is disposed on the inner surface of the material layer 110, and the texture of the fiber texture layer 120 is displayed externally through the material layer 110. The fiber texture layer 120 is protected by the material layer 110, providing increased reliability.
[0108] The material layer 110 and the fiber texture layer 120 can be integrally formed by hot pressing or bonding. A protective ink or paint can be sprayed or silk-screened on the second surface 120b of the fiber texture layer 120 to form a first paint layer 130. The first paint layer 130 can be a dark or light-colored material. Furthermore, the first paint layer 130 may not be provided on the second surface 120b of the fiber texture layer 120.
[0109] In some embodiments, a light-transmitting protective layer is provided on the outer surface of the material layer 110. The outer surface of the material layer 110 is the side of the material layer 110 facing away from the fiber texture layer 120. The light-transmitting protective layer protects the material layer 110. The light-transmitting protective layer can be made of a resin, such as polyurethane, epoxy resin, or UV-curable adhesive.
[0110] In some embodiments, see Figure 5 、 Figure 6 When the material layer 110 serves as the exterior surface 100a of the housing 100, the transparency of the material layer 110 is greater than or equal to 50%. External light can pass through the material layer 110, and light reflected from the fiber texture layer 120 can propagate outward through the material layer 110, allowing the texture of the fiber texture layer 120 to be directly displayed as an exterior effect.
[0111] For example, the transparency of the material layer 110 is greater than or equal to 85%, so that light can pass through the material layer 110 better, thereby allowing the texture of the fiber texture layer 120 to be better presented to the outside.
[0112] In order to improve the surface glossiness of the fiber texture layer 120, in some embodiments, see Figure 8 In the case where the first paint layer 130 serves as the exterior surface 100a of the housing 100, a transparent brightening layer 160 is provided between the first paint layer 130 and the fiber texture layer 120. The transparent brightening layer 160 is applied to the entire second surface 120b of the fiber texture layer 120. The inherent texture of the fiber texture layer 120, combined with the transparent brightening layer 160, can enhance the texture and gloss of the fiber texture layer 120, enhancing the layered appearance of the housing 100. Furthermore, the transparent brightening layer 160 is easy to shape. The transparent brightening layer 160 can be a fully transparent or semi-transparent layer.
[0113] In some embodiments, see Figure 9 In the case where the first paint layer 130 serves as the exterior surface 100a of the housing 100, a transparent brightening layer 160 is provided between the first paint layer 130 and the fiber texture layer 120. The transparent brightening layer 160 is applied to the entire second surface 120b of the fiber texture layer 120. The inherent texture of the fiber texture layer 120, combined with the transparent brightening layer 160, can highlight the texture and gloss of the fiber texture layer 120, enhancing the layered appearance of the housing 100. Furthermore, the transparent brightening layer 160 is easy to form. The transparent brightening layer 160 can have a fully transparent or semi-transparent structure. A second paint layer 150 is provided between the material layer 110 and the fiber texture layer 120. The second paint layer 150 can strengthen the bonding between the material layer 110 and the fiber texture layer 120 and can be used to conceal defects such as pits in the material layer 110. The second paint layer 150 can be made of a resin, such as polyurethane, epoxy resin, or UV-curable adhesive.
[0114] In order to improve the surface glossiness of the fiber texture layer 120, in some embodiments, refer to Figure 10 When the material layer 110 serves as the exterior surface 100a of the housing 100, a transparent brightening layer 160 is disposed between the material layer 110 and the fiber texture layer 120. The transparent brightening layer 160 is disposed entirely over the first surface 120a of the fiber texture layer 120. The inherent texture of the fiber texture layer 120, combined with the transparent brightening layer 160, enhances the texture and gloss of the fiber texture layer 120, enhancing the layered appearance of the housing 100. Furthermore, the transparent brightening layer 160 is easily formed. The transparent brightening layer 160 can be fully transparent or translucent.
[0115] To enhance the surface gloss of the fiber texture layer 120, in some embodiments, when the first paint layer 130 or the material layer 110 serves as the exterior surface 100a of the housing 100, a transparent brightening layer 160 is applied to the outer surface of the fibers in the fiber texture layer 120. The transparent brightening layer 160 is first applied to the outer surface of the fibers, and then the fibers provided with the transparent brightening layer 160 are fabricated to form the fiber texture layer 120. The inherent texture of the fiber texture layer 120, combined with the transparent brightening layer 160 applied to the outer surface of the fibers, enhances the texture and gloss of the fiber texture layer 120, enhancing the layered appearance of the housing 100. Furthermore, the transparent brightening layer 160 is easily formed.
[0116] When setting the material of the transparent brightness enhancing layer 160 , the transparent brightness enhancing layer 160 may include at least one of an optical coating film, a non-conductive vacuum metalization (NCVM) film, and a pearlescent powder layer.
[0117] Optical coating is the process of depositing one or more layers of thin metal or dielectric films on a component's surface, thereby altering the material's reflective and transmissive properties. Metals can include aluminum (Al), chromium (Cr), copper (Cu), nickel (Ni), and others. Dielectric materials can include magnesium fluoride (MgF2), silicon dioxide (SiO2), zirconium oxide (ZrO2), and others.
[0118] Non-conductive vacuum plating film refers to the organic conversion of metal materials under vacuum conditions using chemical and physical means to convert the metal into particles, which are deposited or adsorbed on the surface of the predetermined material to form a film.
[0119] Pearlescent powder, also known as pearlescent pigment, has the shimmering effect of metallic pigments while also producing the soft hue of natural pearls. When exposed to sunlight, it produces multiple layers of reflection, and the interaction of the reflected light creates a vibrant luster and color. Pearlescent powder can be laid down to form a pearlescent layer.
[0120] When setting the thickness of the transparent brightening layer 160 , the thickness of the transparent brightening layer 160 can range from 1 nm to 1 mm. Using the transparent brightening layer 160 in the above thickness range can effectively enhance the glossiness of the fiber texture layer 120 and improve the appearance of the housing 100 .
[0121] When the transparent brightness enhancing layer 160 is disposed on the entire second surface 120b or the entire first surface 120a of the fiber texture layer 120, the transparent brightness enhancing layer 160 can be set to a larger thickness. The transparent brightness enhancing layer 160 is disposed on the outer surface of the fibers in the fiber texture layer 120 and has a smaller thickness.
[0122] See Figures 11 to 14 The embodiment of the present application provides an electronic device 1000, comprising a housing 100. The housing 100 is used to mount components of the electronic device 1000 and provide protection to reduce damage to the components caused by external influences.
[0123] See Figure 3 、 Figure 4 、 Figures 7 to 9 The first paint layer 130 may be a light-transmitting layer to serve as the exterior surface 100 a of the housing 100 , and the user may see the self-textured effect of the fiber texture layer 120 through the first paint layer 130 .
[0124] Alternatively, see Figure 5 、 Figure 6 、 Figure 10 The material layer 110 may be a light-transmitting layer to serve as the exterior surface 100 a of the housing 100 , and a user may see the self-textured effect of the fiber texture layer 120 through the material layer 110 .
[0125] The electronic device 1000 may be a consumer electronic product, a home electronic product, an in-vehicle electronic product, a financial terminal product, a communication electronic product, a mobile device, or the like. Consumer electronic products may include mobile phones, tablet computers, laptop computers, e-readers, personal computers (PCs), personal digital assistants (PDAs), desktop monitors, smart wearable products (e.g., smart watches, smart bracelets), virtual reality (VR) terminal devices, augmented reality (AR) terminal devices, drones, or the like. Home electronic products may include smart door locks, televisions, remote controls, refrigerators, rechargeable small household appliances (e.g., robot vacuums), or the like. In-vehicle electronic products may include in-vehicle navigation systems, in-vehicle high-density digital video discs (DVDs), or the like.

Communication electronic products may include communication equipment such as servers, storage devices, radars, and base stations. Mobile devices may include vehicles, electric skateboards, and electric bicycles, or the like.
[0126] The electronic device 1000 is a mobile phone. Figures 11 to 14 The electronic device 1000 includes a display screen 200, a back shell 170, and a middle frame 180. The display screen 200 and the back shell 170 are respectively arranged on opposite sides of the middle frame 180. The display screen 200 and the middle frame 180 can be connected by bonding or other means. The middle frame 180 and the back shell 170 can be connected by bonding, snap fastening, or other means. The middle frame 180 and the back shell 170 can also be an integrally molded structure. At least one of the back shell 170 and the middle frame 180 can adopt the housing 100 solution of the above embodiment.
[0127] The electronic device 1000 may further include components such as a battery, a mainboard, an earpiece, a speaker, a gyroscope, an accelerometer, and an ambient light sensor, which may be disposed on the middle frame 180 .
[0128] When setting up the housing 100 of the electronic device 1000, in some embodiments, refer to Figure 12 The housing 100 may include a flat plate portion 171 and a frame portion 172, with the frame portion 172 connected to the edge of the flat plate portion 171. The frame portion 172 extends toward the same side as the edge of the flat plate portion 171. When the housing 100 is used in an electronic device 1000 such as a mobile phone or tablet computer, the housing 100 may serve as a back shell 170, with the flat plate portion 171 and the middle frame 180 disposed opposite each other, and the frame portion 172 connected to the middle frame 180.
[0129] In other embodiments, see Figure 13 The shell 100 may include a flat portion 171. When the shell 100 is applied to an electronic device 1000 such as a mobile phone or a tablet computer, the shell 100 may serve as a back shell 170. The flat portion 171 of the shell 100 and the middle frame 180 are arranged opposite to each other, and the flat portion 171 and the middle frame 180 are connected.
[0130] In some embodiments, see Figure 14 The flat plate portion 171 has a boss portion 173, which has a mounting hole for mounting the camera module 300. This facilitates the placement of the camera module 300, which has a certain volume, at the mounting hole of the boss portion 173. This reduces the thickness of the housing 100 outside the boss portion 173, thereby reducing the space occupied by the electronic device 1000.
[0131] When confirming the housing 100 and electronic device 1000 of the embodiment of the present application, the appearance of the housing 100 can be observed to determine whether the fiber texture layer 120 is used. The fiber texture layer 120 has a randomly distributed fiber texture. The housing 100 laminate can be sliced and the composition of the fiber texture layer 120 can be analyzed. The fiber texture layer 120 can be a polyimide fiber paper layer, an aramid fiber paper layer, a flax fiber paper layer, a silk fiber layer, etc. The fiber texture layer 120 can be observed using a scanning electron microscope (SEM). The material of the fiber texture layer 120 can also be analyzed using an energy dispersive spectrometer (EDS).
