[0031] The electronic device provided by the embodiments of the present disclosure is described in detail.

[0032] With the continuous development of science and technology, electronic devices are updated and replaced more and more quickly, and consumers tend to pursue electronic devices with higher appearance performance.

[0033] Exemplarily, in order to make the electronic device more beautiful, the shell is usually made of polyurethane or silicone, and a three-dimensional decoration area is formed on the outer surface of the polyurethane or silicone. For example, the logo of the product, the decoration pattern, etc. At present, in the process of forming a three-dimensional decoration pattern on the outer surface of the polyurethane or silicone, a groove is usually formed on the outer surface of the polyurethane or silicone, and a plastic sheet with the logo or decoration pattern of the product is embedded. On the one hand, the assembly of the plastic sheet and the shell is easy to produce gaps, affecting the delicacy of the shell; on the other hand, the manufacturing cost of the plastic sheet plus the assembly cost of the plastic sheet and the shell increases the manufacturing cost of the shell.

[0034] The electronic device provided by the embodiments of the present disclosure is described in detail.

[0035] The electronic device provided by the embodiments of the present disclosure is described in detail. Figures 1A-5 The electronic device provided by the embodiments of the present disclosure is described in detail.

[0036] Figure 1A The structure of the electronic device according to the embodiments of the present disclosure is schematically shown; Figure 1B The cross-sectional structure of the electronic device according to the embodiments of the present disclosure is schematically shown.

[0037] As shown in Figure 1A and 1B The electronic device 10 of this embodiment includes a body 11.

[0038] The body 11 has a shell 12. The shell 12 includes a first region 121 and a second region 122, and the shell 12 of the first region 121 has a first density, and the shell 12 of the second region 122 has a second density.

[0039] Exemplarily, the electronic device 10 can be any device with a shell. For example, the electronic device 10 can be a mobile phone, a tablet computer, a wearable device such as a smart watch, a notebook computer, a game console, or the like. The embodiments of the present disclosure do not have special restrictions on the specific device form of the electronic device 10.

[0040] The body 11 can be the main body of the electronic device 10. For example, the body 11 can be a mobile phone, a tablet computer, a notebook computer, or the like. The embodiments of the present disclosure are described by taking a mobile phone as an example.

[0041] The shell 12 can be a part of the body 11, and the shell 12 can be used to partially wrap the outer circumferential side of the body 11 so that the devices in the body 11 are not easily exposed. For example, the shell 12 can be a part of the mobile phone that is arranged opposite to the display screen.

[0042] The shell 12 at least includes a first region 121 and a second region 122. The materials of the first region 121, the second region 122, and the shell 12 are the same, the shell 12 of the first region 121 has a first density, the shell 12 of the second region 122 has a second density, and the first density and the second density are different.

[0043] The shell 12 can adopt a hot pressing forming manner to form regions with different densities in the shell 12. In a unit area, different densities can form different thicknesses, thereby forming a concave-convex structure on the shell 12 to form a three-dimensional pattern. The hot pressing forming manner can form the concave-convex structure on the surface of the shell 12 without easily causing gaps.

[0044] If the first region 121 is the main region of the pattern, in the case where the first density is greater than the second density, the first region 121 can protrude from the second region 122, thereby forming a three-dimensional pattern in the form of protrusion on the surface of the shell 12. In the case where the first density is less than the second density, the first region 121 can be lower than the second region 122, thereby forming a three-dimensional pattern in the form of depression on the surface of the shell 12.

[0045] It can be understood that by forming regions with different densities on the surface of the shell 12, a concave-convex structure is formed on the surface of the shell 12, the concave-convex structure is integrally formed with the shell 12 and can present a preset three-dimensional pattern. The three-dimensional pattern is integrally formed with the shell 12 and is not easy to cause gaps, thereby improving the delicacy and aesthetics of the product. At the same time, the preparation of the plastic sheet and the assembly between the plastic sheet and the shell 12 are reduced, thereby reducing the preparation cost of the shell 12.

[0046] According to the embodiments of the present disclosure, in a unit region, the material usage of the first region 121 and the second region 122 is the same.

[0047] In the same material usage, the area with different density can have different thickness.

[0048] When the shell 12 is subjected to external force, the shell 12 can be deformed, resulting in the change of the density of the material in the unit volume. For example, the material in the unit area is compressed, which can cause the thickness of the area to be smaller. And with the gradual increase of the density, the thickness of the shell 12 gradually becomes smaller.

[0049] According to the embodiment of the present disclosure, the first density is less than the second density, and the thickness of the shell 12 of the first area 121 is greater than the thickness of the shell 12 of the second area 122.

[0050] For the same material, in the unit volume, the first density of the first area 121 is less than the second density of the second area 122, and the thickness of the first area 121 is less than the thickness of the second area 122. Therefore, the first area 121 of the shell 12 is protruded from the second area 122, thereby forming a pattern in the form of protrusion on the surface of the shell 12.

[0051] In some embodiments, the thickness of the shell 12 is the same as the thickness of the shell 12 of the first area 121.

[0052] Continuing to refer to Figure 1B , the thickness of the shell 12 of the first area 121 is the same as the thickness of the shell 12, the thickness of the shell 12 of the second area 122 is less than the thickness of the shell 12 of the first area 121, the first area 121 is protruded from the second area 122, that is, a three-dimensional pattern is formed on the surface of the shell 12, and the outer surface of the three-dimensional pattern is flush with the outer surface of the shell 12.

[0053] Figure 2 One of the partial structure schematic diagrams of the electronic device according to the embodiment of the present disclosure is schematically shown.

[0054] In some embodiments, as Figure 2 shown, the thickness D3 of the shell 12 is 0.3-0.5mm. The thickness of the shell 12 of the first area 121 and the thickness of the shell 12 of the second area 122 have a third height difference D4, and the third height difference D4 is 0.11-0.13mm.

[0055] Exemplarily, the thickness D3 of the shell 12 can be 0.3mm, 0.4mm or 0.5mm, etc., and the embodiment of the present disclosure does not specifically limit the thickness of the shell 12.

[0056] Since the first region 121 protrudes from the second region 122, the shell 12 thickness of the first region 121 and the shell 12 thickness of the second region 122 have a third height difference, which can be 0.11, 0.12, 0.13 mm, etc. The present embodiment does not make specific limitations on the third height difference between the shell 12 thickness of the first region 121 and the shell 12 thickness of the second region 122.

[0057] It should be noted that the shell 12 thickness of the first region 121 and the shell 12 thickness of the second region 122 can have multiple third height differences D4. For example, the shell 12 thickness of a part of the first region 121 and the shell 12 thickness of the second region 122 have a third height difference D4 of 0.11 mm; the shell 12 thickness of another part of the first region 121 and the shell 12 thickness of the second region 122 have a third height difference D4 of 0.13 mm. As long as the shell 12 thickness of the first region 121 and the shell 12 thickness of the second region 122 have a height difference, the size of the height difference is not specifically limited.

[0058] According to the present embodiment, the height of the first region 121 gradually increases from the first sub-region 1211 close to the second region 122 to the second sub-region 1212 away from the second region 122.

[0059] Exemplarily, the first sub-region 1211 can be the bottom of the three-dimensional pattern, and the first region 121 is connected to the second region 122 through the first sub-region 1211. The second sub-region 1212 can be the top of the three-dimensional pattern.

[0060] The first region 121 protruding from the second region 122 can adopt a gradual height change form. That is, the width of the first region 121 changes from the first sub-region 1211 close to the second region 122 to the second sub-region 1212 away from the second region 122.

[0061] For example, the circumferential side of the first region 121 can be arranged in an inclined shape, and the width of the first region 121 gradually decreases / increases from the first sub-region 1211 close to the second region 122 to the second sub-region 1212 away from the second region 122. The circumferential side of the first region 121 can also be arranged in an arc shape, and the width of the first region 121 first decreases and then increases or first increases and then decreases from the first sub-region 1211 close to the second region 122 to the second sub-region 1212 away from the second region 122.

[0062] It can be understood that the height of the first region 121 gradually increases in sequence, which can make the three-dimensional pattern have stronger three-dimensional and hierarchical effects.

[0063] According to an embodiment of the present disclosure, the third sub-region 1213 is between the first sub-region 1211 and the second sub-region 1212, the height of the first sub-region 1211 to the third sub-region 1213 increases in sequence with a first unit height growth rate, and the height of the third sub-region 1213 to the second sub-region 1212 increases in sequence with a second unit height growth rate; the first unit height growth rate is different from the second unit height growth rate.

[0064] With reference to the foregoing Figure 2 , the third sub-region 1213 can be the middle part of the three-dimensional pattern. The height of the first sub-region 1211 to the third sub-region 1213 increases in sequence with a first unit height growth rate, and the height of the third sub-region 1213 to the second sub-region 1212 increases in sequence with a second unit height growth rate. The three sub-regions are arranged in sequence, in which the first sub-region 1211 is located at the lowermost, the third sub-region 1213 is located in the middle, and the second sub-region 1212 is located at the uppermost. Therefore, the shape is composed of the three sub-regions, forming a layered structure. The height (or the distance in the vertical direction) from the first sub-region 1211 to the third sub-region 1213 is gradually increased, and the increase is carried out according to the first unit growth rate. Specifically, the first unit height growth rate can represent a fixed growth amplitude, and the amount of each increase is gradually increased according to the proportion. For example, a slope, an inclination or an arc shape. Similarly, the height of the third sub-region 1213 to the second sub-region 1212 is gradually increased according to the first unit height growth rate. For example, a slope, an inclination or an arc shape. The first unit height growth rate is different from the second unit height growth rate, which means that the speeds of the two increases are different. It can be that the height growth speed from the first sub-region 1211 to the third sub-region 1213 is less than the height growth speed from the third sub-region 1213 to the second sub-region 1212; or it can be that the height growth speed from the first sub-region 1211 to the third sub-region 1213 is greater than the height growth speed from the third sub-region 1213 to the second sub-region 1212.

[0065] In one example, the circumferential side of the three-dimensional pattern formed by the first region 121 can be arranged in an arc shape protruding from the outside to the inside. The width of the bottom of the first region to the top of the first region is first increased and then decreased.

[0066] It can be understood that the arc design helps to uniformly disperse the external force or internal force acting on the periphery of the three-dimensional pattern, avoiding stress concentration at the right angle or sharp corners. Sharp corners are usually stress concentration points, which are easy to cause material cracks, breakage and other problems. The arc can smoothly transition and reduce such stress concentration, thereby improving the durability of the design.

[0067] Figure 3A second schematic diagram of a partial structure of an electronic device according to an embodiment of the present disclosure is shown.

[0068] According to an embodiment of this disclosure, the first region 121 includes a pointed sub-region 1214, which is arc-shaped.

[0069] For example, the sharp corner sub-region 1214 can be a corner portion in a three-dimensional pattern. That is, the portion formed by a change in the direction of the peripheral lines of the pattern. From the first side to the second side of the sharp corner sub-region 1214, the angle of the originally straight line becomes a smooth transition, forming a curved shape. The rate of increase of the curve from the first side to the second side of the sharp corner sub-region 1214 gradually decreases.

[0070] like Figure 3 As shown, the pointed sub-region 1214 can be arranged by bending from one side to the other towards the outside of the three-dimensional pattern.

[0071] Understandably, curved designs help to evenly distribute external or internal forces acting around the pattern, avoiding stress concentration at right angles or sharp corners.

[0072] Figure 4 One of the structural schematic diagrams of the housing 12 according to an embodiment of the present disclosure is shown.

[0073] According to embodiments of this disclosure, such as Figure 4 As shown, the housing 12 includes a support layer 12a and a decorative layer 12b.

[0074] The support layer 12a is made of a first material; the decorative layer 12b is made of a second material; the decorative layer 12b is located on the outer surface of the shell 12 and covers the support layer 12a.

[0075] The support layer 12a can be the bottom layer of the shell 12, serving as the inner layer of the shell 12. The support layer 12a provides support for the decorative layer 12b. For example, the support layer 12a can be a layer structure formed of a first material: glass fiber and resin. The decorative layer 12b can be the surface layer of the shell 12, serving as the outer layer of the shell 12. The decorative layer 12b provides decoration for the support layer 12a. For example, the decorative layer 12b can be a layer structure formed of a second material: silicone, or it can be a layer structure formed of a second material: PU (polyurethane, artificial leather). It should be noted that the embodiments disclosed in this paper do not specifically limit the materials of the support layer 12a and the decorative layer 12b. As long as the support layer 12a has good hardness and the decorative layer 12b has aesthetic appeal, the two can be stacked to form the shell 12.

[0076] The support layer 12a has a first region 121 and a second region 122, and the decorative layer 12b also has a first region 121 and a second region 122. The first region 121 and the second region 122 of the support layer 12a and the first region 121 and the second region 122 of the decorative layer 12b are arranged correspondingly.

[0077] In one example, the glass fiber is impregnated in the resin, and then solidified to form a solid composite material: pre-impregnated glass fiber. The support layer 12a formed by the pre-impregnated glass fiber has good hardness. If the pre-impregnated glass fiber material is used, although the hardness requirement of the shell 12 can be met, the shell 12 is not beautiful enough. If PU / silicone is used, although the requirement of the shell 12 can be met, the hardness does not meet the requirement.

[0078] In the related art, an integrally formed shell with a pattern is usually prepared by a material through a mold hot injection molding method. For two materials with application effects, the preparation requirement cannot be met. Therefore, the support layer formed by the pre-impregnated glass fiber is stacked with the PU / silicone, and then a three-dimensional pattern is formed on the surface of the decorative layer through hot pressing. On the one hand, the support layer can provide good support for the decorative layer formed by the PU. On the other hand, the decorative layer of the PU and the integrally formed pattern have high aesthetics, and the shell can be improved in appearance.

[0079] According to the embodiment of the present disclosure, the support layer 12a and the decorative layer 12b are connected through the adhesive material.

[0080] The adhesive material can be a connecting material for connecting the support layer 12a and the decorative layer 12b, and the support layer 12a and the decorative layer 12b can be connected as a whole through the adhesive material. For example, when the support layer 12a is a metal material and the decorative layer 12b is a glass material, the adhesive material can be polyurethane glue, epoxy resin, etc.

[0081] In other embodiments, the support layer 12a and the decorative layer 12b can be connected according to the characteristics of the materials. For example, in the case where the support layer 12a is pre-impregnated glass fiber and the decorative layer 12b is PU, since the resin in the mixed pre-impregnated glass fiber has viscosity, it can help the glass fiber to combine with the PU. Therefore, the mixed pre-impregnated glass fiber can be coated on the inner side of the PU to form the support layer 12a on the inner side of the PU.

[0082] According to the embodiment of the present disclosure, the support layer 12a includes a first support layer 13 and a second support layer 14, and the first region 121 of the first support layer 13 and the second region 122 of the first support layer 13 have a first height difference, and the first region 121 of the second support layer 14 and the second region 122 of the second support layer 14 have a second height difference.

[0083] Exemplarily, the support layer 12a can be composed of one or more layers. For example, the support layer 12a can be composed of two layers of the first support layer 13 and the second support layer 14.

[0084] The first support layer 13 and the second support layer 14 each have a first region 121 and a second region 122. During the process of hot-pressing the shell 12, the second regions 122 of the decorative layer 12b, the first support layer 13 and the second support layer 14 are extruded, so as to form a first region 121 and a second region 122 (a three-dimensional pattern) on the decorative layer 12b, the first support layer 13 and the second support layer 14.

[0085] In other embodiments, the support layer 12a can also be composed of three layers of the first support layer 13, the second support layer 14 and the third support layer 15.

[0086] It can be understood that the multi-layer support layer 12a can provide good support for the decorative layer 12b, while also ensuring the mechanical strength of the shell 12 and prolonging the service life of the electronic device 10.

[0087] In the embodiments of the present disclosure, the support layer 12a is prepared by the method of multi-layer support layer 12a stacking, which can ensure that each layer of the support layer 12a is coated more uniformly. A single layer of thick coating may

[0088] According to the embodiments of the present disclosure, the first support layer 13 covers the second support layer 14, and the decorative layer 12b covers the first support layer 13. The first height difference D1 is greater than the second height difference D2.

[0089] During the multi-layer hot-pressing process, the deformation degree of the bottom layer material is relatively small due to the small pressure, low temperature and slow heat conduction of the bottom layer material. Therefore, the deformation amount of the second support layer 14 located at the bottom layer of the shell 12 is smaller than that of the first support layer 13. The first height difference D1 of the first region 121 and the second region 122 in the first support layer 13 is greater than the second height difference D2 of the first region 121 and the second region 122 in the second support layer 14. The deformation amounts of the first support layer 13 and the second support layer 14 are both smaller than the deformation amount of the decorative layer 12b.

[0090] In order to facilitate a better understanding of the structure of the shell of the embodiments of the present disclosure, the following will be combined with Figure 5 The preparation of the shell is described.

[0091] Figure 5 The structure of the shell according to the embodiments of the present disclosure is schematically shown.

[0092] AsFigure 5 As shown, a mold is provided, the mold comprising a female mold and a male mold matched with the female mold, and the inner wall of the female mold has a preset three-dimensional pattern. The three-dimensional pattern is matched with the first region and the second region.

[0093] In the manufacturing process, the glass fiber is impregnated in the resin to form a pre-impregnated glass fiber, the pre-impregnated glass fiber is coated on the inner surface of the silicone (decorative layer), and then cured to form the first support layer. A layer of pre-impregnated glass fiber is coated on the side of the first support layer away from the silicone, and after curing, a second support layer is obtained, thereby obtaining a flexible plate composed of a support layer and a decorative layer.

[0094] The flexible plate is placed in the mold, the mold is heated to a preset temperature, a first pressure is applied to the flexible plate placed in the heated mold for a first time period, and a second pressure is applied for a second time period to obtain a first intermediate body, the first intermediate body having a first region and a second region. The second time period is the continuation of the first time period, wherein the preset temperature is 110-140°C. The first time period is 40-60s, the first pressure is 5-10T, the second time period is 200-300s, and the second pressure is 20-35T.

[0095] The first intermediate body is subjected to baking treatment to obtain a second intermediate body, the baking temperature being 110-140°C and the baking time being 80-95s.

[0096] The second intermediate body is processed by CNC (Computer Numerical Control) technology, and the processed second intermediate body is laminated, etc., to obtain a shell.
