Shell, electronic device and manufacturing method of shell

[0001] The present application claims priority to the Chinese patent application No. 202411398103.8, filed on September 30, 2024, and entitled "Shell, electronic device and manufacturing method of shell", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the technical field of electronic devices, and in particular to a shell, an electronic device and a manufacturing method of the shell. BACKGROUND

[0003] With the development of society, the appearance of electronic devices is diversified. Forging carbon is formed by cutting carbon fibers into carbon sheets, and the carbon fiber composite material is formed by forging and pressing the carbon sheets and resin. The carbon sheets can form an appearance texture, and the forging carbon can be used to form a shell of an electronic device. The current carbon sheets have low dispersion and uneven dispersion in the resin, which affects the appearance effect of the shell. SUMMARY

[0004] The present application provides a shell, an electronic device and a manufacturing method of the shell. The present application improves the dispersion of carbon sheets in resin and the uniform dispersion of carbon sheets by designing the shell, and the shell has excellent appearance texture.

[0005] In a first aspect, the present application provides a shell. The shell includes carbon sheets and resin, the carbon sheets are distributed in the resin, the carbon sheets form the appearance texture of the shell, and the carbon sheets include fiber filaments. Since the resin is usually transparent, the carbon sheets distributed in the resin can be seen, and the shape, size and position of the carbon sheets form the unique appearance texture of the shell. The fiber filaments can be short fibers. For example, the length of the short fiber 211 can be less than 100 mm.

[0006] The resin includes a flexible side chain for adjusting the position distribution of the carbon sheets in the resin to form the appearance texture, and / or the shell includes a spherical filler distributed in the resin for adjusting the position distribution of the carbon sheets in the resin to form the appearance texture.

[0007] It can be understood that the resin can be in a film shape, and the carbon sheets can be distributed on the cured film-shaped resin, and the carbon sheets and the resin are forged and pressed by high temperature and high pressure to form a carbon fiber composite material, which can also be called forged carbon, and the shell can be formed by machining and the like. After the carbon sheets are distributed on the cured film-shaped resin, the resin is melted by high temperature, and the resin is in a flowing state, and the resin flows by high pressure and the flowing property of the resin itself to drive the carbon sheets to move. Therefore, the flowing property of the resin affects the distribution of the carbon sheets and the appearance texture of the shell. After the carbon sheets are distributed on the film-shaped resin, the carbon sheets may exist in a stacking condition, and the stacking conditions of the carbon sheets at different positions can be different, that is, the carbon sheets are more stacked at some positions and less stacked at some positions, and the stacking of the carbon sheets affects the appearance texture of the shell and makes the appearance texture more disorderly. For example, when two rhombic carbon sheets are stacked and do not completely overlap, the appearance formed by the two rhombic carbon sheets is no longer rhombic and has uncertainty, and the texture is more disorderly.

[0008] In the embodiments of the present application, the resin includes flexible side chains, and / or the spherical fillers are distributed in the resin, so that the flowing property of the resin is enhanced to drive the carbon sheets to move, the resin with high flowing property drives the carbon sheets to move, the dispersion degree and uniformity of the carbon sheets in the resin are improved, excellent appearance texture is formed, and a brand-new appearance experience and use experience are brought to users. In addition, by enhancing the flowing property of the resin, the resin can be fully pressed by applying appropriate pressure, and the thinness of the shell is facilitated.

[0009] In a possible implementation, the flexible side chains include amino groups. The polyurethane can be used to react with functional groups of the resin to form the flexible side chains. In the embodiments of the present application, the flexible side chains include amino groups, so that the resin has good flowing property, and the carbon sheets form excellent appearance texture in the resin.

[0010] In a possible implementation, the diameter of the spherical filler is less than or equal to 60 um. In the embodiments of the present application, the diameter of the spherical filler is less than or equal to 60 um, so that the flowing property of the resin before curing is improved, and the carbon sheets form excellent appearance texture in the resin. When the diameter of the spherical filler is greater than 60 um, the spherical filler affects the smoothness of the surface of the shell. In addition, the spherical filler can increase the volume of the resin, produce a microsphere effect, promote the flowing property of the resin, and produce isotropy to ensure the dimensional stability of the product.

[0011] In a possible implementation, the mass ratio of the spherical filler to the resin is less than or equal to 15%. In the embodiments of the present application, the mass ratio of the spherical filler to the resin is less than or equal to 15%, so that the surface of the shell is smooth and has good surface performance. If the mass ratio of the spherical filler to the resin is greater than 15%, the spherical filler is too much and the resin is too little, and the surface performance of the shell is affected.

[0012] In a possible implementation, the shell comprises a curing agent, and a mass ratio of the curing agent to the resin is less than or equal to 40%. The shell according to the embodiment of the present application can prolong the curing time of the resin, so that the resin has sufficient time to flow and can sufficiently press the carbon sheets to form an excellent appearance texture. The resin with high fluidity can drive the carbon sheets to move, which is beneficial to forming an excellent appearance texture and achieving thinning of the shell.

[0013] In a possible implementation, the shell comprises a filler, the filler is distributed in the resin, and the filler is at least one of silicon carbide powder, silicon nitride powder, silicon dioxide powder, polytetrafluoroethylene resin, and polytetrafluoroethylene powder. The shell according to the embodiment of the present application can significantly improve the wear resistance of the shell without affecting the appearance texture of the shell, and does not need to be provided with a wear-resistant coating on the surface of the shell, thereby meeting the requirement of being free of coating and simplifying the process.

[0014] In a possible implementation, a mass ratio of the filler to the resin is less than or equal to 10%. The shell according to the embodiment of the present application can improve the wear resistance of the shell and ensure the surface smoothness of the shell.

[0015] In a possible implementation, any one of the silicon carbide powder, the silicon nitride powder, and the silicon dioxide powder has a particle size less than or equal to 100 um. The shell according to the embodiment of the present application can improve the wear resistance of the shell without affecting the strength and the appearance texture of the shell. If the particle size of any one of the silicon carbide powder, the silicon nitride powder, and the silicon dioxide powder is greater than 100 um, the strength of the shell is low, and the shell is easily damaged.

[0016] In a possible implementation, the polytetrafluoroethylene powder has a particle size less than or equal to 60 um. The shell according to the embodiment of the present application can improve the self-lubricating property of the resin, meet the wear resistance requirement of the shell, and does not affect the strength and the appearance texture of the shell.

[0017] In a possible implementation, the shell comprises a connecting layer and an ink layer, and the connecting layer is located between the resin layer in which the carbon sheets are distributed and the ink layer. The connecting layer can be a resin film, which is used to increase the bonding force between the ink layer and the resin layer in which the carbon sheets are distributed. It can be understood that the carbon sheets can be distributed on the surface of the resin, and the bonding force between the carbon sheets and the ink layer is poor, while the bonding force between the resin and the ink is good. Therefore, a layer of resin film (i.e., the connecting layer) needs to be compounded on the resin layer in which the carbon sheets are distributed, so as to increase the bonding force between the ink layer and the resin layer in which the carbon sheets are distributed. By arranging the ink layer on the surface of the resin layer in which the carbon sheets are distributed, the gloss of the shell can be improved, and the hand feeling of the shell is better.

[0018] In a possible implementation, the shell comprises a long fiber layer, the fiber length of the long fiber layer is greater than the fiber length in the carbon sheets, and the long fiber layer is arranged in a stack with the resin layer in which the carbon sheets are distributed. The long fiber layer has a long fiber length, which can provide sufficient strength to the shell, facilitate the thinning of the shell, and avoid light leakage. It can be understood that the short fibers in the carbon sheets have a short length, and gaps are prone to exist between the short fibers. Resin exists in the gaps, and the resin is transparent, which can cause light leakage. By arranging the long fiber layer, the light leakage can be avoided.

[0019] In a possible implementation, the long fiber layer is located between two adjacent resin layers in which the carbon sheets are distributed. By arranging the long fiber layer between the two adjacent resin layers in which the carbon sheets are distributed, the shell has appearance textures on both surfaces, which can provide a good visual effect for a user.

[0020] In a possible implementation, the long fiber layer comprises at least two layers, and the at least two layers of the long fiber layer are arranged in a stack. By arranging the at least two layers of the long fiber layer in a stack, sufficient strength can be provided to the shell, the thinning of the shell is facilitated, and light leakage can be avoided.

[0021] In a possible implementation, the long fiber layer is at least one of a carbon fiber, a glass fiber, a poly-p-phenylene benzobisoxazole fiber, and a polyimide fiber. The carbon fiber, the glass fiber, the poly-p-phenylene benzobisoxazole fiber, and the polyimide fiber have strong puncture resistance, and can provide sufficient strength to the shell. In addition, since the long fiber layer has strong puncture resistance, even if the thickness of the long fiber layer is thin, sufficient strength can be provided to the shell, and the thinning of the shell is facilitated. In other embodiments, the long fiber layer can also be other fiber materials that have good cross-linking with the resin.

[0092] It can be understood that since the resin 22 is usually transparent, the carbon sheets 21 distributed in the resin 22 can be seen, and the shape, size, position, etc. of the carbon sheets 21 form the unique appearance texture of the housing 20.

[0093] The carbon sheet 21 can include a plurality of fiber filaments, which can be short fibers 211. The length of the short fibers 211 can be less than 100 mm, such as 6 mm, 12 mm, 24 mm, or 32 mm, etc. The present embodiments are not limited thereto, and the length of the short fibers 211 can be obtained as needed.

[0094] In FIG. 3, the number of carbon sheets 21 is sixteen, and one of the carbon sheets 21 includes six short fibers 211. It can be understood that the number of carbon sheets 21 can also be less than sixteen or greater than sixteen, and the number of short fibers 211 included in each carbon sheet 21 can also be less than six or greater than six, etc. The present embodiments are not limited thereto, and can be set as needed. It can be understood that only the short fibers 211 in one carbon sheet 21 are shown in FIG. 3, and the short fibers 211 are also included in the other carbon sheets 21, which are not shown in FIG. 3.

[0095] In FIG. 3, the shape of the carbon sheet 21 is a rhombus, but the shape of the carbon sheet 21 is not limited to a rhombus, and can also be a crescent or a cloud stream line, etc. The cloud stream line can also be understood as an irregular wave shape. The sizes of the plurality of carbon sheets 21 in FIG. 3 can be the same or different. The shapes of the plurality of carbon sheets 21 in FIG. 3 can be the same or different. The shape, size, position, etc. of the carbon sheet 21 in FIG. 3 are only schematically represented.

[0096] In some embodiments, the resin 22 can include a flexible side chain. The flexible side chain can be used to adjust the position distribution of the carbon sheet 21 in the resin 22 to form an excellent appearance texture. The side chain refers to a smaller molecular unit connected to the main chain of the polymer, and the flexible side chain refers to a side chain that can increase the flexibility of the polymer chain. The flexible side chain is usually small in volume and non-polar, because such a side chain can reduce the rigidity of the polymer chain and increase its flexibility. The flexible side chain can increase the flowability of the resin to increase the uniformity of the dispersion of the carbon sheet 21 in the resin 22.

[0097] Exemplarily, the flexible side chain can include an amino group. The polyurethane can be used to react with the functional groups of the resin to form the flexible side chain. The present embodiments provide that the flexible side chain includes an amino group, so that the resin has good flowability, which is conducive to forming an excellent appearance texture of the carbon sheet 21 in the resin 22.

[0098] Referring to FIG. 4, in some embodiments, the shell 20 can include a spherical filler 23. The spherical filler 23 is distributed in the resin 22, and is used to adjust the position distribution of the carbon sheet 21 in the resin 22 to form an excellent appearance texture. The spherical filler 23 has a smooth surface, which can increase the flowability of the resin. Only one spherical filler 23 is schematically shown in FIG. 4, and it can be understood that more spherical fillers 23 can be included in the resin 22, which is not limited by the present embodiments.

[0099] The spherical filler 23 can be hollow glass microspheres, which are light in mass and can be used as fillers. The spherical filler 23 can also be nanoparticles or silicon carbide powder, etc.

[0100] Exemplarily, the diameter of the spherical filler 23 is less than or equal to 60 um. For example, the diameter of the spherical filler 23 can be 5 um, 10 um, 15 um, 20 um, 25 um, 30 um, 35 um, 40 um, 45 um, 50 um or 55 um, etc. By setting the diameter of the spherical filler 23 to be less than or equal to 60 um, the resin flowability before curing can be improved, so that the carbon sheet 21 forms an excellent appearance texture in the resin 22. When the diameter of the spherical filler 23 is greater than 60 um, the spherical filler 23 will affect the smoothness of the surface of the shell 20. In addition, the spherical filler 23 can also increase the volume of the resin, produce a microsphere effect, promote the flowability of the resin, and at the same time produce isotropy to ensure the dimensional stability of the product.

[0101] In some embodiments, the mass ratio of the spherical filler to the resin is less than or equal to 15%. For example, the mass ratio of the spherical filler to the resin can be 3%, 7%, 10%, 13% or 14%, etc. By setting the mass ratio of the spherical filler to the resin to be less than or equal to 15%, the surface of the shell 20 can be smooth and have good surface properties. If the mass ratio of the spherical filler to the resin is greater than 15%, the amount of the spherical filler is too much and the amount of the resin is too little, which will affect the surface properties of the shell 20.

[0102] In other embodiments, the resin 22 can include flexible side chains and the spherical filler 23 is distributed in the resin 22, and the flexible side chains and the spherical filler 23 can both be used to adjust the distribution of the carbon sheet 21 in the resin 22.

[0103] It can be understood that the resin 22 can be in a film shape, and the carbon sheet 21 can be distributed on the cured film-shaped resin 22. The carbon sheet 21 and the resin 22 can be forged and pressed to form a carbon fiber composite material by high temperature and high pressure, which can also be referred to as forged carbon. The shell 20 can be formed by mechanical processing, etc. After the carbon sheet 21 is distributed on the cured film-shaped resin 22, the resin 22 is melted by high temperature, and the resin 22 is in a flowing state. The resin 22 flows by high pressure and the flowability of the resin 22 itself to move the carbon sheet 21. Therefore, the flowability of the resin 22 affects the distribution of the carbon sheet 21 and the appearance texture of the shell 20.

[0104] The resin 22 has high fluidity, and the resin 22 can drive the carbon sheets 21 to move, so that the carbon sheets 21 are dispersed and uniformly dispersed, which is beneficial to form an excellent appearance texture and bring a brand-new appearance experience and use experience to a user. In addition, the resin 22 has high fluidity, so that a suitable pressure can be fully applied to the resin 22, and the resin 22 is fully pressed, which is beneficial to realize thinning of the shell 20.

[0105] In some embodiments, the shell 20 can further include a curing agent, and a mass ratio of the curing agent to the resin is less than or equal to 40%. For example, the mass ratio of the curing agent to the resin can be 20%, 25%, 30%, 35%, or the like. The shell 20 can have a curing time of the resin greater than or equal to 30 minutes, so that the resin has sufficient time to flow and can fully press the carbon sheets to form an excellent appearance texture. The resin 22 has high fluidity, which is beneficial to form an excellent appearance texture and realize thinning of the shell 20.

[0106] In some embodiments, the shell 20 can have a thickness less than or equal to 0.5 mm, for example, the thickness of the shell 20 can be 0.45 mm or 0.5 mm, or the like, which realizes thinning of the shell 20.

[0107] In some embodiments, the shell 20 can further include a filler 24, and the filler 24 is distributed in the resin 22. The filler 24 can be at least one of silicon carbide powder, silicon nitride powder, silicon dioxide powder, polytetrafluoroethylene resin, and polytetrafluoroethylene powder. For example, the filler 24 can be any one of, or any two of, or any three of, or the like, silicon carbide powder, silicon nitride powder, silicon dioxide powder, polytetrafluoroethylene resin, and polytetrafluoroethylene powder, which can be set as needed, and the embodiments of the present application do not limit this.

[0108] The shell 20 can be obviously improved in wear resistance by adding the filler 24, and the appearance texture of the shell 20 is not affected, the wear-resistant coating does not need to be arranged on the surface of the shell, the coating-free requirement is met, and the process is simplified.

[0109] For example, the particle size of any one of the silicon carbide powder, the silicon nitride powder and the silicon dioxide powder is less than or equal to 100 um. For example, the particle size of any one of the silicon carbide powder, the silicon nitride powder and the silicon dioxide powder can be 90 um, 80 um, 70 um, 60 um, 50 um, 40 um, 30 um, 20 um or 10 um, etc. The particle size of the powder can be understood as the maximum distance between any two points on the surface of the powder. For example, when the powder is spherical, the particle size of the powder is the diameter of the spherical powder, and when the powder is long strip-shaped, the particle size of the powder is the distance between the most distant two points on the cuboid. The particle size of any one of the silicon carbide powder, the silicon nitride powder and the silicon dioxide powder is less than or equal to 100 um in the embodiment of the application, which can improve the wear resistance of the shell 20, and will not affect the strength of the shell 20, nor the appearance texture of the shell 20. If the particle size of any one of the silicon carbide powder, the silicon nitride powder and the silicon dioxide powder is greater than 100 um, the strength of the shell 20 will be low, and the shell 20 will be easily damaged.

[0110] For example, the particle size of the polytetrafluoroethylene powder is less than or equal to 60 um. For example, the particle size of the polytetrafluoroethylene powder can be 5 um, 10 um, 15 um, 20 um, 25 um, 30 um, 35 um, 40 um, 45 um, 50 um or 55 um, etc. The particle size of the polytetrafluoroethylene powder is less than or equal to 60 um in the embodiment of the application, which can improve the self-lubricity of the resin, meet the wear resistance requirement of the shell 20, and will not affect the strength of the shell 20, nor the appearance texture of the shell 20.

[0111] In some embodiments, the ratio of the mass of the filler to the mass of the resin is less than or equal to 10%. For example, the ratio of the mass of the filler to the mass of the resin can be 2%, 5% or 8%, etc. The ratio of the mass of the filler to the mass of the resin is less than or equal to 10% in the embodiment of the application, which is beneficial to enhancing the wear resistance of the shell, and ensuring the surface smoothness of the shell.

[0112] As shown in FIG. 5, FIG. 5 is a structural schematic view of another shell 20 shown in FIGS. 1 and 2. The shell 20 can include a connecting layer 25 and an ink layer 26, the connecting layer 25 is located between the resin 22 with the distributed carbon sheets 21 and the ink layer 26. The connecting layer 25 can be a resin film, which is used to increase the bonding force between the ink layer 26 and the resin 22 with the distributed carbon sheets 21. When the connecting layer 25 is a resin film, there can be no obvious boundary between the connecting layer 25 and the resin 22 with the distributed carbon sheets 21. It can be understood that the carbon sheets 21 can be distributed on the surface of the resin 22, the bonding force between the carbon sheets 21 and the ink layer 26 is poor, and the bonding force between the resin and the ink is good, therefore, a layer of resin film (i.e. the connecting layer 25) is needed to be compounded on the resin 22 with the distributed carbon sheets 21 to increase the bonding force between the ink layer 26 and the resin 22 with the distributed carbon sheets 21. By setting the ink layer 26 on the surface of the resin 22 with the distributed carbon sheets 21, the glossiness of the shell 20 can be improved, and the hand feeling of the shell 20 is better.

[0113] Referring to FIG. 5, it can be understood that the shell 20 can include a first surface 212 and a second surface 213 arranged oppositely, the first surface 212 is the surface of the ink layer 26, and the second surface 213 is the surface of the resin 22 with the distributed carbon sheets 21, and the first surface 212 can be the appearance surface of the shell 20.

[0114] As shown in FIG. 6, FIG. 6 is a structural schematic view of another shell 20 shown in FIGS. 1 and 2. The shell 20 can include a long fiber layer (including a first long fiber layer 271, a second long fiber layer 272 and a third long fiber layer 273), the fiber length of the long fiber layer is greater than the short fiber length of the carbon sheets 21, the long fiber layer is arranged in a stack with the resin 22 with the distributed carbon sheets 21, and the long fiber layer supports the resin 22 with the distributed carbon sheets 21 in strength to improve the overall strength of the shell 20. The fiber length of the carbon sheets 21 refers to the length of the short fibers 211 in the carbon sheets 21. The fiber length of the long fiber layer is long, which can provide sufficient strength for the shell 20, is conducive to the thinning of the shell 20, and can avoid light leakage. It can be understood that the length of the short fibers 211 in the carbon sheets 21 is short, and there are gaps between the short fibers 211, and there is resin in the gaps. The resin is transparent, and there can be light leakage. By setting the long fiber layer, light leakage can be avoided.

[0115] The number of long fiber layers can be one, two, three, four, or five, and so on. FIG. 6 shows an example in which the number of long fiber layers is three, and the three long fiber layers are a first long fiber layer 271, a second long fiber layer 272, and a third long fiber layer 273. The first long fiber layer 271, the second long fiber layer 272, and the third long fiber layer 273 are stacked in sequence on the same side of the resin 22 in which the carbon sheets 21 are distributed, and the other side of the resin 22 in which the carbon sheets 21 are distributed is the appearance side of the shell 20, which has excellent appearance texture. That is, the side on which the long fiber layers in FIG. 6 are located has no appearance texture, and the side on which the resin 22 in which the carbon sheets 21 are distributed is located is the appearance side of the shell, which has excellent appearance texture.

[0116] The plurality of long fibers in the first long fiber layer 271 can be arranged in a first direction, the plurality of long fibers in the second long fiber layer 272 can be arranged in a second direction, and the plurality of long fibers in the third long fiber layer 273 can be arranged in a third direction. That is, the first long fiber layer 271, the second long fiber layer 272, and the third long fiber layer 273 are all unidirectional fiber layers. The first direction can be any direction, the second direction is different from the first direction, the third direction is different from the second direction, and the third direction can be the same as or different from the first direction. For example, the second direction can be perpendicular to the first direction, the third direction can be perpendicular to the second direction, and the third direction can be the same as the first direction. The arrangement directions of the long fibers in the two adjacent long fiber layers are different and staggered, which is beneficial to enhancing the strength of the shell 20.

[0117] For example, the plurality of long fibers in the first long fiber layer 271 can be arranged in the first direction and combined together by the resin.

[0118] In other embodiments, the long fiber layer can also be a woven fiber layer, that is, the fibers in the long fiber layer are arranged in different directions to form a woven fiber layer, which can provide sufficient strength to the shell 20.

[0119] The thickness H of the resin 22 in which the carbon sheets 21 are distributed can be greater than or equal to 0.20 mm. For example, the thickness H of the resin 22 in which the carbon sheets 21 are distributed can be 0.25 mm, 0.30 mm, or 0.35 mm, and so on. The present application sets the thickness of the resin 22 in which the carbon sheets 21 are distributed to be greater than or equal to 0.20 mm, so that the appearance texture of the shell 20 is relatively stable. If the thickness of the resin 22 in which the carbon sheets 21 are distributed is less than 0.20 mm, the carbon sheets 21 are prone to fall off from the resin 22, causing appearance defects of the shell 20.

[0120] The thicknesses of the first long fiber layer 271, the second long fiber layer 272, and the third long fiber layer 273 can be the same or different, and can be set as needed. The thicknesses of the first long fiber layer 271, the second long fiber layer 272, and the third long fiber layer 273 can each be greater than or equal to 0.10 mm, such as 0.15 mm, 0.20 mm, or 0.25 mm. By setting the thicknesses of the first long fiber layer 271, the second long fiber layer 272, and the third long fiber layer 273 to each be greater than or equal to 0.10 mm, the shell 20 can be provided with sufficient strength, and light leakage can be avoided. The total thickness of the long fiber layer and the resin having the carbon sheet distributed therein can be greater than or equal to 0.3 mm.

[0121] The long fiber layer can be at least one of carbon fiber, glass fiber, poly-p-phenylene benzobisoxazole fiber, or polyimide fiber. For example, the long fiber layer can be any one of, or any two of, or any three of carbon fiber, glass fiber, poly-p-phenylene benzobisoxazole fiber, or polyimide fiber, which can be set as needed, and embodiments of the present application do not limit the same.

[0122] Carbon fiber, glass fiber, poly-p-phenylene benzobisoxazole fiber, and polyimide fiber have strong puncture resistance, and can provide the shell 20 with sufficient strength. In addition, because the long fiber layer has strong puncture resistance, even if the thickness of the long fiber layer is thin, the shell 20 can still be provided with sufficient strength, which is conducive to the thinness of the shell 20. In other embodiments, the long fiber layer can also be other fiber materials that have good cross-linking with the resin 22. The long fibers in the long fiber layer are not shown in FIG. 6.

[0123] Referring to FIG. 6, it can be understood that the shell 20 can include a third surface 214 and a fourth surface 215 arranged opposite to each other, the third surface 214 being a surface of the resin 22 having the carbon sheet 21 distributed therein, and the fourth surface 215 being a surface of the third long fiber layer 273, and the third surface 214 can be an appearance surface of the shell 20.

[0124] Referring to FIG. 6, a connecting layer and an ink layer (not shown in FIG. 6) can be arranged on the third surface 214 of the shell 20, and the arrangement of the connecting layer and the ink layer can be specifically referred to the arrangement of the connecting layer and the ink layer in FIG. 5. The connecting layer can be a resin film, and can be used to increase the bonding force between the ink layer and the resin having the carbon sheet distributed therein. The ink layer can improve the gloss of the shell, and make the shell have a better hand feeling. When the ink layer is arranged on the third surface 214, the surface of the ink layer is an appearance surface of the shell 20.

[0125] As shown in FIG. 7 and FIG. 8, FIG. 7 is a structural schematic diagram of another shell 20 shown in FIG. 1 and FIG. 2, and FIG. 8 is a structural schematic diagram of the shell 20 shown in FIG. 7 from another angle. The long fiber layer (including the first long fiber layer 271, the second long fiber layer 272, and the third long fiber layer 273) is located between the two adjacent layers of the resin 22 distributed with the carbon sheet 21. It can be understood that the shell 20 in FIG. 7 can also include one long fiber layer, two long fiber layers, or four long fiber layers, etc. The embodiment of the present application sets the long fiber layer between the two adjacent layers of the resin 22 distributed with the carbon sheet 21, so that both surfaces of the shell 20 have the appearance texture, which can provide a good visual effect for the user. In other embodiments, the long fiber layer can also not be set between the two layers of the resin 22 distributed with the carbon sheet 21.

[0126] The appearance texture in the upper layer of the resin 22 distributed with the carbon sheet 21 and the lower layer of the resin 22 distributed with the carbon sheet 21 can be the same or different. Due to the randomness of the forging carbon manufacturing process, the shape, size, and distribution position of the carbon sheet 21 will affect the appearance texture, so the possibility of the appearance texture in the upper layer of the resin 22 distributed with the carbon sheet 21 and the lower layer of the resin 22 distributed with the carbon sheet 21 being different is relatively large. Exemplarily, the surface 221 of the upper layer of the resin 22 distributed with the carbon sheet 21 away from the long fiber layer can adopt the appearance texture shown in FIG. 3, and the surface 222 of the lower layer of the resin 22 distributed with the carbon sheet 21 away from the long fiber layer can adopt the appearance texture shown in FIG. 8. In other words, FIG. 3 can be a view of the upper layer of the resin 22 distributed with the carbon sheet 21 away from the long fiber layer, and FIG. 8 can be a view of the lower layer of the resin 22 distributed with the carbon sheet 21 away from the long fiber layer. The distribution of the carbon sheet 21 in the upper layer of the resin 22 distributed with the carbon sheet 21 and the lower layer of the resin 22 distributed with the carbon sheet 21 is different, and the appearance texture formed is different. The long fibers in the long fiber layer are not shown in FIG. 7.

[0127] Referring to FIG. 7, it can be understood that either of the surface 221 of the upper layer of the resin 22 distributed with the carbon sheet 21 away from the long fiber layer and the surface 222 of the lower layer of the resin 22 distributed with the carbon sheet 21 away from the long fiber layer can be used as the appearance surface of the shell 20, which can be selected as needed.

[0128] Referring to FIG. 7, the connecting layer and the ink layer (not shown in FIG. 7) can be arranged on the surface 221 of the resin 22 with the carbon sheets 21 arranged thereon of the upper layer of the shell 20 away from the long fiber layer or the surface 222 of the resin 22 with the carbon sheets 21 arranged thereon of the lower layer away from the long fiber layer, referring to the arrangement of the connecting layer and the ink layer in FIG. 5. The connecting layer can be a resin film, which is used to increase the bonding force between the ink layer and the resin with the carbon sheets arranged thereon. The ink layer can improve the gloss of the shell and make the shell have a better hand feeling. When the ink layer is arranged on the surface 221 of the resin 22 with the carbon sheets 21 arranged thereon of the upper layer away from the long fiber layer or the surface 222 of the resin 22 with the carbon sheets 21 arranged thereon of the lower layer away from the long fiber layer, the surface of the ink layer is the appearance surface of the shell 20.

[0129] In FIG. 8, the number of the carbon sheets 21 is seventeen, and one of the carbon sheets 21 includes six short fibers 211. It can be understood that the number of the carbon sheets 21 can also be less than seventeen or more than seventeen, and the number of the short fibers 211 included in each carbon sheet 21 can also be less than six or more than six, and the like, which are not limited in the embodiments of the present application and can be arranged as needed. It can be understood that the short fibers 211 are only schematically shown in one of the carbon sheets 21 in FIG. 8, and the short fibers 211 are also included in the other carbon sheets 21, which are not shown in FIG. 8.

[0130] In FIG. 8, the shape of the carbon sheet 21 is a rhombus, which is only an example and is not limited to the rhombus. The shape of the carbon sheet 21 can also be a crescent or a cloud stream line, and the like. The shape, size, position, and the like of the carbon sheet 21 in FIG. 8 are only schematically shown.

[0131] In some embodiments, a resin film can be compounded on the surface of the shell 20. The resin can be selected from, but is not limited to, an epoxy resin or a polycarbonate resin, and the like, which is beneficial to increase the smooth texture of the surface of the shell 20 and achieve the smooth feeling of the appearance texture of the shell 20. Color powder can be added in the resin film to adjust the colorful color.

[0132] Referring to FIG. 9, FIG. 9 is a flowchart of a manufacturing method of a shell 20. The embodiments of the present application provide a manufacturing method of a shell 20. The manufacturing method of the shell 20 in one embodiment specifically includes the following steps:

[0133] S101, manufacturing a carbon sheet 21.

[0134] Referring to FIG. 10, FIG. 10 is a schematic diagram of a manufacturing process of the carbon sheet 21. S1011, the carbon yarn 210 is cut to form the carbon sheet 21. The solid line in FIG. 10 can represent the fiber in the carbon yarn 210, and the dashed line in FIG. 10 represents the cutting position. The dashed line in the figure can also be located at other positions. The length of the carbon sheet 21 can be controlled by controlling the moving speed of the carbon yarn 210 and the cutting speed. For example, the carbon sheet 21 is longer when the moving speed of the carbon yarn 210 is faster, and the carbon sheet 21 is shorter when the cutting speed is faster. FIG. 10 takes the carbon sheet 21 as an example in the form of a rectangle. It can be understood that the carbon sheet 21 in the form of a rectangle has a plurality of short fibers. S1012, the carbon sheet 21 after cutting is subjected to rolling treatment, and the carbon sheet 21 is deformed by high pressure. For example, the fibers are dispersed by high pressure, the carbon sheet 21 in the form of a rectangle is deformed, and the carbon sheet 21 in the form of a rhombus is formed.

[0135] Referring to FIG. 11, FIG. 11 is a schematic diagram of another manufacturing process of the carbon sheet 21. A special-shaped cutter is designed to cut the carbon yarn 210 to form a carbon sheet 21 in the form of a cloud pattern streamline. The dashed line in FIG. 11 represents the cutting position. The dashed line in the figure can also be located at other positions.

[0136] In other embodiments, a special-shaped cutter can be designed to cut the carbon yarn 210 to form a carbon sheet 21 in the form of a crescent or other shapes, so as to realize the diversification of the appearance.

[0137] S102, providing a resin.

[0138] The resin is in a flowing state without curing, so as to add the required substances in the resin. The resin can be an epoxy resin, a phenolic resin, a vinyl resin, or the like. The embodiments of the present application do not limit the type of the resin.

[0139] S103, providing a reactant, reacting the reactant with the resin to form a flexible side chain, and / or providing a spherical filler, and dispersing the spherical filler in the resin.

[0140] In some embodiments, the reactant can be a polyurethane. The polyurethane reacts with the functional groups of the resin to form a flexible side chain, so that the resin has good fluidity, which is beneficial to forming an excellent appearance texture of the carbon sheet 21 in the resin 22.

[0141] In some embodiments, the ratio of the mass of the polyurethane to the mass of the resin is less than or equal to 20%. For example, the ratio of the mass of the polyurethane to the mass of the resin can be 3%, 7%, 10%, 15%, or 18%, etc. The embodiments of the present application set the ratio of the mass of the polyurethane to the mass of the resin to be less than or equal to 20%, which is beneficial to ensuring that the resin has sufficient fluidity and does not affect the strength of the shell 20. If the ratio of the mass of the polyurethane to the mass of the resin is greater than 20%, the strength of the shell 20 will be reduced.

[0142] After adding reactants and / or spherical fillers, as well as at least one desired substance from the curing agent and filler selection, to the resin, the added substances are stirred evenly with the resin. The addition of a dispersing agent can prevent the added substances from agglomerating. For example, after adding silicon carbide or silicon nitride, the dispersion of the silicon carbide or silicon nitride needs to meet a spacing greater than 30 μm.

[0143] S104. Curing the resin.

[0144] The resin is cured to form a film. Understandably, after the resin is cured, a semi-solid resin film can be formed, that is, the resin is not completely cured and has a sticky texture.

[0145] S105. Press the carbon sheet and resin together.

[0146] Carbon sheets are distributed on the surface of cured resin, and then pressed together with the resin under high temperature and pressure, forming the textured appearance of the shell. Understandably, under high temperature and pressure, the cured resin melts into a fluid state, giving it fluidity. This allows the resin to move the carbon sheets, improving the uniformity of carbon sheet dispersion within the resin.

[0147] Carbon sheets can be pressed together with resin using a roller press. The applied pressure range can be greater than or equal to 20 kg and less than or equal to 60 kg, meaning the weight of the rollers is greater than or equal to 20 kg and less than or equal to 60 kg.

[0148] To control the uniformity of carbon sheet 21 dispersion in resin 22, the step thickness of carbon sheet 21 can be less than or equal to 0.15 mm by controlling the blade speed and roller pressure. The step thickness of carbon sheet 21 refers to the difference between its maximum and minimum thickness. For example, the step thickness of carbon sheet 21 can be 0.05 mm, 0.08 mm, 0.10 mm, or 0.13 mm, etc.

[0149] Understandably, after the carbon flakes 21 are distributed on the film-like resin 22, the carbon flakes 21 may accumulate. Moreover, the accumulation of carbon flakes 21 may vary in different locations, with some locations having more carbon flakes 21 and others having less. This accumulation of carbon flakes 21 will affect the appearance and texture of the shell 20, resulting in a highly chaotic texture. For example, if one carbon flake 21 is rhomboid, the appearance formed when two rhomboid carbon flakes 21 are stacked but not completely overlapped will no longer be rhomboid and will have an uncertain shape, leading to a highly chaotic texture.

[0150] In this embodiment, by setting the resin 22 to include flexible side chains and / or distributing spherical fillers 23 in the resin 22, the flowability of the resin 22 can be enhanced to drive the carbon sheet 21 to move, thereby improving the dispersion and uniformity of the carbon sheet 21 in the resin 22 and forming an excellent appearance texture.

[0151] Referring to FIG. 6, in some embodiments, the shell 20 comprises long fiber layers (a first long fiber layer 271, a second long fiber layer 272, and a third long fiber layer 273). The long fiber layers can be combined with the resin distributed with carbon sheets by hot pressing. For example, the long fiber layers and the resin distributed with carbon sheets are laid up, the resin distributed with carbon sheets is located on one side of the long fiber layers, the long fiber layers and the resin distributed with carbon sheets 21 are placed in a hot pressing mold for hot pressing to form the shell 20, which is simple in process and strong in bonding force. The structure, number of layers, and laying position of the long fiber layers are described above and will not be repeated here.

[0152] Referring to FIG. 7, the resin distributed with carbon sheets is two layers, and the two layers of resin distributed with carbon sheets are laid up on opposite sides of the long fiber layers. The long fiber layers and the two layers of resin distributed with carbon sheets 21 are placed in a hot pressing mold for hot pressing to form the shell 20.

[0153] Referring to FIG. 5, in some embodiments, the shell comprises a connecting layer 25 and an ink layer 26. The connecting layer 25 can be combined with the resin distributed with carbon sheets 21 by hot pressing, the ink layer is sprayed on the side of the connecting layer 25 away from the resin distributed with carbon sheets 21, and the ink layer 26 is transferred to form a texture on the ink layer 26. For example, the connecting layer 25 and the resin distributed with carbon sheets 21 are laid up, and then hot pressed, which is simple in process and strong in bonding force.

[0154] The shell 20 can be designed by processes such as transfer printing or spraying according to requirements to implement a coating appearance texture and increase design diversity.

[0155] In some embodiments, the surface of the shell 20 can be cut in a direction perpendicular to the thickness of the shell 20 by a computer numerical control (CNC) process to change the appearance texture of the shell 20. For example, the side of the thinner resin distributed with carbon sheets 21 can be processed by the CNC process to change the appearance texture of the shell 20. Or both sides of the thicker resin distributed with carbon sheets 21 can be processed by the CNC process, such as the thickness of the resin distributed with carbon sheets 21 before the CNC process can be greater than or equal to 1 mm, and the thickness of the shell 20 formed by the CNC process can be less than or equal to 0.5 mm. For example, the thickness of the resin distributed with carbon sheets 21 before the CNC process can be 1.2 mm, 1.4 mm, or 1.6 mm, etc.

[0156] For example, referring to FIG. 7, the surface 221 and the surface 222 can be processed by the CNC process to change the appearance texture of the shell 20 to achieve a unique texture. Understandably, the present application can also not be provided with the long fiber layer, but only the relatively thick carbon sheet 21 and the resin 22, and the double sides of the relatively thick carbon sheet 21 and the resin 22 can be processed by the CNC process. The embodiment of the present application can avoid the warping in the process of processing the resin 22 with the carbon sheet 21 by the CNC process.

[0157] Understandably, the unique appearance texture can also be formed by adding minerals, metal powder, etc. in the resin to increase the diversity of the appearance of the shell 20.

[0158] In some embodiments, the resin 22 with the carbon sheet 21 is processed by the CNC process to form the shell 20 with the characteristic structure, which reduces the parts, is conducive to reducing the risk of the reliability of the whole machine caused by the assembly problem of the parts, and is conducive to reducing the cost. The characteristic structure can be a limiting structure or other structure. The thickness of different positions of the shell 20 can be the same or different. The shell 20 can be processed into a two-dimensional plate or a three-dimensional curved shape according to the needs.

[0159] In some embodiments, the resin 22 with the carbon sheet 21 is processed by the CNC process to form the required logo. The logo can be a brand name or a brand icon, etc. The specific form of the logo is not limited in the embodiment of the present application.

[0160] Understandably, the shell 20 can be used as a separate structural part. The shell 20 can be the back shell of the electronic device 100. The shell 20 can also be matched with other structural parts to form a shell assembly 30. The embodiment of the present application takes the shell 20 matched with the mounting part 40 as the shell assembly 30 as an example for introduction. The mounting part 40 is the back shell of the electronic device 100, and the shell 20 is a decorative part. The embodiment of the present application takes the shell 30 processed into a three-dimensional curved curved surface structure as an example for introduction. For example, referring to FIGS. 12 to 22.

[0161] As shown in FIGS. 12, 13 and 14, FIG. 12 is a structural schematic diagram of one shell assembly 30 shown in FIG. 2. The shell 20 in FIG. 12 is assembled to the mounting part 40. FIG. 12 is a structural schematic diagram on the side where the appearance surface of the shell assembly 30 is located. FIG. 13 is a structural schematic diagram of the shell assembly 30 shown in FIG. 12 from another angle. FIG. 13 is a structural schematic diagram on the side where the inner surface of the shell assembly 30 is located. FIG. 14 is an exploded structural schematic diagram of the shell assembly 30 shown in FIG. 12.

[0162] It can be understood that the shell assembly 30 can be used in an electronic device that is not foldable, or can be used in an electronic device that is foldable. When the shell assembly 30 is used in an electronic device that is foldable, the shell assembly 30 can not cover the folding mechanism of the electronic device (for example, the folding mechanism can be a rotating shaft), or the shell assembly 30 can cover the folding mechanism of the electronic device. When the shell assembly 30 covers the folding mechanism of the electronic device, the shell 20 can not cover the folding mechanism of the electronic device, the number of the mounting pieces 40 can be two, and the shell 20 can be assembled on one of the mounting pieces 40, or when the shell assembly 30 covers the folding mechanism of the electronic device, the shell 20 covers the folding mechanism of the electronic device, and the shell 20 can include two parts, and the two parts of the shell 20 are assembled on the two mounting pieces 40 respectively, the two parts of the shell 20 can be separated when the electronic device is closed, and the two parts of the shell 20 abut to be integrated when the electronic device is opened. The embodiments of the present application take the shell assembly 30 used in an electronic device that is not foldable or the shell 20 not covering the folding mechanism of the electronic device as an example.

[0163] The shell assembly 30 includes the shell 20 and the mounting piece 40. The mounting piece 40 can include a recess 41, which can be formed by the surface of the mounting piece 40 being inwardly recessed. The shell 20 can be fixed in the recess 41. The depth of the recess 41 can be 0.45 mm. The depth of the recess 41 is not limited in the embodiments of the present application and can be set as required.

[0164] It can be understood that the position, shape, size, etc. of the shell 20 in FIG. 12 are only schematically represented and can be set as required, which is not limited in the embodiments of the present application.

[0165] The shell 20 and the mounting piece 40 can be fixedly connected by injection molding or gluing, and the connection mode of the shell 20 and the mounting piece 40 is not limited in the embodiments of the present application. The shell 20 and the mounting piece 40 are connected by gluing in the embodiments of the present application. For example, a dispensing machine can be arranged in the recess 41 of the mounting piece 40 to dispense glue according to a preset dispensing path, then the shell 20 is installed in the recess 41 and is pressed to firmly fix the shell 20 to the mounting piece 40 after the glue is solidified. Alternatively, a hot-pressing glue film 412 can be arranged in the recess 41, then the shell 20 is installed in the recess 41 and is hot-pressed to firmly bond the shell 20 to the mounting piece 40. Alternatively, the shell 20 can be firmly fixed to the mounting piece 40 by dispensing and hot-pressing the glue film 412, thereby improving the connection reliability between the shell 20 and the mounting piece 40.

[0166] In some embodiments, the recess 41 of the mounting piece 40 can be provided with a radio frequency grounding portion 411, and the radio frequency grounding portion 411 is provided with conductive foam, and the conductive foam is electrically connected to the shell 20 to achieve grounding of the shell 20.

[0167] Referring to FIG. 14 and FIG. 15, FIG. 15 is a structural schematic diagram of the mounting piece 40 shown in FIG. 12. The recess 41 is provided with a broken hole 413, which is a hole structure penetrating the inner wall of the recess 41 from top to bottom, or an irregular through hole penetrating from top to bottom. The edge portion of the mounting piece 40 can be curved, and the end portion of the shell 20 is curved to match the shape of the mounting piece 40, so as to realize the close fit of the shell 20 and the mounting piece 40. Then one end or both ends of the recess 41 formed are curved. When the recess 41 is opened on the mounting piece 40, the wall of the curved edge portion of the mounting piece 40 is relatively thin, and the broken hole 413 may appear, which has no bonding surface that can bond the shell 20 and the mounting piece 40, and reduces the connection reliability of the shell 20 and the mounting piece 40 at the broken hole 413.

[0168] The hole wall of the broken hole 413 can include a first limiting structure 419. The first limiting structure 419 includes a first inclined surface 414. The first inclined surface 414 is arranged at an angle with the thickness direction of the shell assembly 30, that is, the first inclined surface 414 is inclined relative to the thickness direction of the shell assembly 30.

[0169] The first limiting structure 419 includes a first matching portion 415. The first matching portion 415 can be a dovetail convex portion. The dovetail convex portion is a structure whose size gradually increases from one end to the other end. The size of the end of the dovetail convex portion connected with the hole wall of the broken hole 413 is smaller. Here, the size refers to the size of the dovetail convex portion in the direction X, which is perpendicular to the thickness direction of the shell and perpendicular to the arrangement direction of the two ends of the dovetail convex portion. FIG. 14 takes three first matching portions 415 as an example, and the number of the first matching portions 415 can also be one, two, four, or five, etc., which is not limited in the embodiments of the present application. The first matching portion 415 can also be other structures except the dovetail convex portion. When the number of the first matching portions 415 is two or more, the plurality of first matching portions 415 can be arranged at intervals. The first matching portion 415 and the first inclined surface 414 can be located on the same side of the broken hole 413, and the first inclined surface 414 and the first matching portion 415 can be alternately arranged. In other embodiments, the first matching portion 415 and the first inclined surface 414 can also be located on different sides of the broken hole 413.

[0170] The mounting piece 40 is provided with a first clamping groove 4161 and a second clamping groove 4162, the first clamping groove 4161 is located at one end of the mounting piece 40, and the second clamping groove 4162 is located at the other end of the mounting piece 40.

[0171] Referring to FIGS. 14 and 15, the mounting member 40 is provided with first slots 417, which are located between the first clamping slots 4161 and the broken holes 413. The number of the first slots 417 can be one, two, three, or the like. FIG. 14 shows an example in which the number of the first slots 417 is two, and the two first slots 417 are arranged at intervals.

[0172] The mounting member 40 is provided with second slots 418, which can be one, two, three, or the like. FIG. 14 shows an example in which the number of the second slots 418 is three, and the three second slots 418 are arranged at intervals.

[0173] As shown in FIGS. 15, 16, and 17, FIG. 16 is a structural schematic view of the shell 20 shown in FIG. 12, and FIG. 17 is a sectional view of the shell assembly 30 at A-A. The side of the shell 20 facing the mounting member 40 is provided with a boss 281, which can be located at one end of the shell 20. The boss 281 can be a protruding structure protruding from the surface of the shell 20. The boss 281 is embedded in the broken hole 413 to block the broken hole 413. After the boss 281 of the shell 20 blocks the broken hole 413, the shell assembly 30 can be provided with an outer complete appearance surface, and the strength of the shell assembly 30 is increased to avoid damage to the shell assembly 30. The shell 20 can serve as a decorative piece of the shell assembly 30.

[0174] The boss 281 includes a side wall 2813, which can be a flat regular structure or an irregular structure. The side wall 2813 is used to fit the hole wall of the broken hole 413. It can be understood that the boss 281 can also include oppositely arranged top and bottom walls, and the top wall is fixedly connected to the inner surface of the shell 20. The side wall 2813 is connected between the top wall and the bottom wall. The side wall 2813 of the boss 281 includes a second limiting structure 2814. The second limiting structure 2814 cooperates with the first limiting structure 419. The second limiting structure 2814 includes a second inclined surface 2811, which is arranged at an angle with respect to the thickness direction of the shell assembly 30, that is, the second inclined surface 2811 is inclined with respect to the thickness direction of the shell assembly 30. The thickness direction of the shell 20 is consistent with the thickness direction of the shell assembly 30. The second inclined surface 2811 cooperates with the first inclined surface 414 of the mounting member 40 to limit the shell 20 and the mounting member 40 in the thickness direction, so that the shell 20 cannot move away from the mounting member 40, which is beneficial to improve the stability of the connection between the shell 20 and the mounting member 40 and to achieve reliable connection between the shell 20 and the mounting member 40.

[0175] Referring to FIG. 17, in some embodiments, the second inclined surface 2811 has a mating angle a with the first inclined surface 414 greater than or equal to 45° and less than or equal to 75°. The mating angle of the second inclined surface 2811 with the first inclined surface 414 refers to the included angle between the first inclined surface 414 and the direction perpendicular to the thickness of the housing assembly 30. Exemplarily, the mating angle a of the second inclined surface 2811 with the first inclined surface 414 can be 50°, 55°, 60°, 65°, or 70°, etc. By setting the mating angle a of the second inclined surface 2811 with the first inclined surface 414 greater than or equal to 45° and less than or equal to 75°, it is beneficial to achieve the limiting of the housing 20 and the mounting member 40 in the thickness direction and facilitate the installation of the housing 20 and the mounting member 40. If the mating angle a of the second inclined surface 2811 with the first inclined surface 414 is less than 45°, it is difficult to embed the boss 281 of the housing 20 into the broken hole 413 of the mounting member 40, and if the mating angle a of the second inclined surface 2811 with the first inclined surface 414 is greater than 75°, it is difficult to achieve the limiting of the housing 20 and the mounting member 40 in the thickness direction.

[0176] Referring to FIGS. 13, 15, and 16, the second limiting structure 2814 includes a second mating portion 2812 which cooperates with the first mating portion 415 to achieve the limiting in the direction perpendicular to the thickness of the housing assembly 30, which is beneficial to improve the stability of the connection between the housing 20 and the mounting member 40. The second mating portion 2812 can be a dovetail groove, and the dovetail convex portion (the first mating portion 415) is embedded in the dovetail groove (the second mating portion 2812).

[0177] In other embodiments, the first mating portion 415 can be a dovetail groove, and the second mating portion 2812 is a dovetail convex portion which is embedded in the dovetail groove to achieve the limiting in the direction perpendicular to the thickness of the housing assembly.

[0178] As shown in FIGS. 15, 16 and 17, the end of the shell 20 is provided with a first clamping protrusion 2821 and a second clamping protrusion 2822. The first clamping protrusion 2821 is located at one end of the shell 20, and the second clamping protrusion 2822 is located at the other end of the shell 20. The first clamping protrusion 2821 is located in the first clamping groove 4161, and the second clamping protrusion 2822 is located in the second clamping groove 4162, so as to limit the thickness direction of the shell assembly. The end of the shell is arc-shaped, and when the arc-shaped shell 20 is fitted with the arc-shaped mounting member 40, it is easy to cause the shell 20 to be not tightly fitted and to be warped, which causes unstable connection between the shell 20 and the mounting member 40 and affects the strength of the shell assembly 30. In the embodiment of the present application, the first clamping protrusion 2821 and the second clamping protrusion 2822 are arranged at the arc-shaped end of the shell 20, and the first clamping protrusion 2821 is located in the first clamping groove 4161 and the second clamping protrusion 2822 is located in the second clamping groove 4162, so that the end of the shell 20 is tightly fitted with the mounting member 40 and cannot be warped, thereby ensuring the reliable connection between the end of the shell 20 and the end of the mounting member 40 and avoiding adverse phenomena such as delamination, deformation and cracking.

[0179] Referring to FIG. 17, in some embodiments, taking the first clamping groove 4161 as an example, the included angle γ between the two groove walls of the first clamping groove 4161 is greater than or equal to 50° and less than or equal to 75°. Exemplarily, the included angle γ between the two groove walls of the first clamping groove 4161 is 55°, 60° or 70°, that is, the fitting angle between the first clamping protrusion 2821 and the first clamping groove 4161 is 70°. If the included angle between the two groove walls of the first clamping groove 4161 is too large, it is difficult to limit the thickness direction of the shell assembly, and it is easy to cause the shell 20 to be not tightly fitted and to be warped. If the included angle between the two groove walls of the first clamping groove 4161 is too small, the first clamping protrusion 2821 of the shell 20 cannot be clamped into the first clamping groove 4161 of the mounting member 40.

[0180] As shown in FIGS. 15 and 16, the surface of the shell 20 facing the mounting member 40 is provided with a first insertion bone 283. The first insertion bone 283 is located at one arc-shaped end of the shell 20. The number of the first insertion bone 283 can be one, two or three, and FIG. 16 takes two as an example. The two first insertion bones 283 are arranged at intervals. The first insertion bone 283 is arranged in one-to-one correspondence with the first insertion slot 417 and is inserted into the first insertion slot 417. In the embodiment of the present application, the first insertion bone 283 and the first insertion slot 417 are arranged in cooperation, which can limit the direction perpendicular to the thickness of the shell assembly 30, is conducive to realizing the stable connection between the shell 20 and the mounting member 40, improves the connection reliability between the end of the shell 20 and the end of the mounting member 40, and avoids adverse phenomena such as delamination, deformation and cracking.

[0181] As shown in FIG. 15, FIG. 16 and FIG. 18, FIG. 18 is a sectional view of the shell assembly 30 shown in FIG. 12 at B-B. The surface of the shell 20 towards the mounting member 40 is provided with second insertion bones 284. The second insertion bones 284 are located at the other arc-shaped end of the shell 20. The number of the second insertion bones 284 can be one, two or three, etc. FIG. 16 takes the number of the second insertion bones 284 as three as an example, and the three second insertion bones 284 are arranged at intervals. The second insertion bones 284 are arranged one by one corresponding to the second insertion slots 418, and the second insertion bones 284 are inserted into the second insertion slots 418. The embodiments of the present application can realize limiting in the thickness direction of the shell assembly 30 by arranging the second insertion bones 284 and the second insertion slots 418 to cooperate, which is beneficial to realize stable connection of the shell 20 and the mounting member 40, improve the connection reliability of the end of the shell 20 and the end of the mounting member 40, and avoid adverse phenomena such as glue separation, deformation and cracking, etc.

[0182] In some embodiments, the depth of the second insertion slot 418 is greater than or equal to 0.5 mm. The embodiments of the present application are beneficial to realize stable connection of the shell 20 and the mounting member 40, improve the connection reliability of the end of the shell 20 and the end of the mounting member 40, and avoid adverse phenomena such as glue separation, deformation and cracking, etc. by arranging the depth of the second insertion slot 418 to be greater than or equal to 0.5 mm. In other embodiments, the depth of the second insertion slot 418 can also be less than 0.5 mm.

[0183] In combination with the embodiments shown in FIG. 13 to FIG. 18, referring to FIG. 19, FIG. 19 is a structural schematic view of another shell assembly 30 shown in FIG. 2, FIG. 19 is a structural schematic view of the side where the inner surface of the shell assembly 30 is located, and the shell 20 in FIG. 19 is assembled to the mounting member 40. The difference between the shell assembly 30 shown in FIG. 19 and the shell assembly 30 shown in FIG. 13 to FIG. 18 includes but is not limited to the difference of the limiting structure. For example, the first matching part 415 can be a T-shaped groove, and the second matching part 2812 is a T-shaped protrusion, the T-shaped protrusion is embedded into the T-shaped groove to realize limiting in the thickness direction perpendicular to the shell assembly. Alternatively, the first matching part 415 can be a T-shaped protrusion, and the second matching part 2812 is a T-shaped groove, the T-shaped protrusion is embedded into the T-shaped groove to realize limiting in the thickness direction perpendicular to the shell assembly. The specific structure of the first matching part 415 and the second matching part 2812 is not limited in the embodiments of the present application.

[0184] With reference to the embodiments shown in FIGS. 13-18, FIGS. 20, 21 and 22 are provided. FIG. 20 is a structural schematic view of another housing assembly 30 shown in FIG. 2, which is a structural schematic view of the side where the inner surface of the housing assembly 30 is located, and the housing 20 is assembled to the mounting member 40. FIG. 21 is an exploded structural schematic view of the housing assembly 30 shown in FIG. 20. FIG. 22 is a structural schematic view of the housing 20 shown in FIG. 21. The housing assembly 30 shown in FIGS. 20-22 is different from the housing assembly 30 shown in FIGS. 13-18 in that the limiting structure is different, the opening of the mounting member 40 is different, and the structure of the housing 20 is different. For example, the mounting member 40 is provided with a through hole 42, and the housing 20 is located in the through hole 42. The through hole 42 extends from one end of the mounting member 40 to the other end of the mounting member 40. The hole wall of the through hole 42 is provided with a first matching part 415. The housing 20 is provided with an embedded part 29, and the embedded part 29 is provided with a second matching part 2812. The embedded part 29 extends from one end of the housing 20 to the other end of the housing 20. It can be understood that the embedded part 29 extends between the two ends of the housing 20, and the extension size of the embedded part 29 between the two ends of the housing 20 is large, which can occupy most of the area of the housing 20, rather than being arranged at only one end of the housing 20. The edge of the embedded part 29 can overlap the edge of the housing 20, or a small gap can be provided.

[0185] In the embodiments of the present application, the embedded part 29 is located in the through hole 42, and the first matching part 415 cooperates with the second matching part 2812 to limit in the direction perpendicular to the thickness of the housing assembly, which is beneficial to improve the stability of the connection between the housing and the mounting member.

Alternatively, the first matching part 415 can be a T-shaped protrusion, and the second matching part 2812 can be a T-shaped groove. The T-shaped protrusion is embedded in the T-shaped groove to limit in the direction perpendicular to the thickness of the housing assembly. Alternatively, the first matching part 415 can be a dovetail protrusion, and the second matching part 2812 can be a dovetail groove. The dovetail protrusion is embedded in the dovetail groove. Alternatively, the first matching part 415 can be a dovetail groove, and the second matching part 2812 can be a dovetail protrusion. The dovetail protrusion is embedded in the dovetail groove to limit in the direction perpendicular to the thickness of the housing assembly. The specific structure of the first matching part 415 and the second matching part 2812 is not limited in the embodiments of the present application.

[0187] It can be understood that the housing 20 can be a one-piece structure, and the mounting member 40 can be a one-piece structure, which has high structural strength, simple process and low cost.

[0188] As shown in FIG. 23, FIG. 23 is a manufacturing and assembling flowchart of the shell 20 and the mounting member 40. The mounting member 40 can be made of metal material, such as magnesium alloy or aluminum alloy, or non-metal material, such as plastic or glass fiber. The embodiment of the present application takes the mounting member 40 made of magnesium alloy as an example. The mounting member 40 can be processed by CNC process to form the recess 41 (see FIG. 14) or the through hole 42 (see FIG. 21). In addition, other structural features can also be formed on the mounting member 40 by CNC process, which are used to adapt to the structures to be installed in the electronic device 100. According to different requirements, any structural features of the mounting member 40 can be realized, which avoids adding new parts to realize the structural features, and is beneficial to reduce the manufacturing cost of the mounting member 40. The mounting member 40 is subjected to micro-arc oxidation treatment to increase the corrosion resistance of the surface of the mounting member 40, and to increase the surface roughness and the surface energy of the mounting member 40. The adhesion. The mounting member 40 can be sprayed with different colors of paint according to requirements to increase the appearance diversity and excellent visual effect of the mounting member 40, and to realize different color effects. The adhesive surface is removed by laser engraving during assembly, to ensure that the surface energy of the bonding surface is greater than 34A (dynes value), and the mounting member 40 can also be subjected to plasma cleaning to increase the surface energy. The mounting member 40 of the embodiment of the present application adopts CNC process to form an integrated structure with complex internal structure, which reduces the parts, is beneficial to reduce the reliability risk of the whole machine caused by the assembly problem of the parts, and is beneficial to reduce the cost.
