Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of terminal, in particular to a shell and electronic equipment. BACKGROUND

[0002] With the development of technology, electronic equipment such as mobile phones, tablets, and laptops are increasingly widely used in people's daily life. In order to improve the user experience, a paint layer is usually provided on the shell to change the texture or color of the shell. However, when the shell is subjected to impact or falling, the paint layer may crack, affecting the integrity of the shell of the electronic equipment, and the cracks may damage the visual effect of the shell, thereby damaging the user experience. CONTENT OF THE UTILITY MODEL

[0003] The present application provides a shell and electronic equipment for reducing the possibility of cracking of the paint layer of the shell.

[0004] The present application provides a shell applied to electronic equipment, the shell comprising:

[0005] a base;

[0006] a paint layer provided on one side of the base in the thickness direction of the shell;

[0007] wherein the thickness of the base is 0.25mm to 0.4mm, and the modulus of the base is 20Gpa to 30Gpa.

[0008] In this way, the modulus of the base can be increased by 10% to 15%, so that the modulus of the base can reach 20Gpa to 30Gpa, and the shell has higher structural strength, so that when the shell is subjected to impact, falling, or the like, the deformation amount of the base is smaller, and therefore the possibility of cracking of the paint layer provided on the surface of the base can be reduced. At the same time, since the mechanical properties of the base are improved, the thickness of the base can be reduced within a certain range when the shell is manufactured, and thus the overall thickness of the shell can be reduced, which is beneficial to cost reduction and miniaturization design of the electronic equipment.

[0009] In one possible implementation, the shell comprises at least one filling layer, and the filling layer is located on the side of the base facing the paint layer.

[0010] The filling layer is located between the base and the paint layer, and is used to improve the flatness of the surface of the base, so as to facilitate the arrangement of the paint layer and improve the stability of the paint layer, and better meet the actual use requirements. At the same time, the filling layer can have a certain color according to requirements, and is used to adjust the color of the shell, so as to meet the visual requirements of the shell.

[0011] In a possible implementation, the filling layer is a polyurethane layer, and a thickness of the filling layer is 0.6 microns to 1.2 microns along a thickness direction of the shell.

[0012] The polyurethane layer has good strength and toughness, and can reduce the possibility of cracking of the shell. The polyurethane layer can be used to fill the surface of the base, thereby improving the flatness to facilitate the arrangement of the paint layer.

[0013] In a possible implementation, the shell includes a connecting layer between the base and the filling layer, and the filling layer is connected to the base through the connecting layer. A thickness of the connecting layer is 8 microns to 15 microns.

[0014] The connecting layer can be an adhesive layer, so that the filling layer can be arranged on the base, thereby improving the stability of the arrangement of the filling layer and meeting the actual use requirements. When the thickness of the connecting layer is less than 8 microns, the thickness of the connecting layer is too small, which reduces the connecting effect of the connecting layer and affects the stability of the connection between the filling layer and the base. When the thickness of the connecting layer is greater than 15 microns, the thickness of the connecting layer is too large, which affects the overall size of the shell.

[0015] In a possible implementation, the paint layer includes a first texture layer, a second texture layer, and a buffer layer. The first texture layer is located on a side of the buffer layer away from the base along a thickness direction of the shell, and the second texture layer is located on a side of the buffer layer toward the base.

[0016] The first texture layer is used to change the tactile effect of the shell, and the second texture layer is used to change the visual effect of the shell. The buffer layer can adjust the overall color of the shell. In addition, the buffer layer has good toughness, which can play a buffering role and reduce the possibility of cracking of the first texture layer and the second texture layer.

[0017] In a possible implementation, the first texture layer is an ultraviolet layer, and a thickness of the first texture layer is 18 microns to 25 microns along a thickness direction of the shell.

[0018] The second texture layer is an ultraviolet layer, and a thickness of the second texture layer is 20 microns to 25 microns along a thickness direction of the shell.

[0019] The first texture layer can be a surface UV layer. By arranging a corresponding texture on the surface UV layer, the tactile feeling of a user when using the electronic device can be changed, thereby improving the user experience. The second texture layer can be a bottom UV layer. By arranging a corresponding texture on the bottom UV layer, the visual effect of the user on the shell of the electronic device can be changed, thereby improving the user experience.

[0020] In a possible implementation, the buffer layer is a polyurethane layer, and a thickness of the buffer layer is 4 micrometers to 10 micrometers along a thickness direction of the shell.

[0021] The PU layer can improve the toughness of the paint layer and reduce the possibility of cracking of the paint layer.

[0022] In a possible implementation, the paint layer further includes a plating layer, the plating layer is located between the buffer layer and the second texture layer along the thickness direction of the shell, and a thickness of the plating layer is 100 nanometers to 400 nanometers.

[0023] The plating layer can be used to improve the gloss and brightness of the paint layer, thereby improving the visual effect of the shell and improving the user experience. When the thickness of the plating layer is small, the plating layer has a poor effect on improving the gloss and brightness. When the thickness of the plating layer is large, the plating layer has poor structural strength, and thus, when the plating layer cracks, the other structures of the paint layer are easily affected, and the paint layer is cracked and damaged.

[0024] In a possible implementation, the substrate is a glass fiber layer or an aramid layer, and a thickness of the substrate is 0.3 millimeters to 0.4 millimeters, or a thickness of the substrate is 0.25 millimeters to 0.35 millimeters.

[0025] The substrate is a polyimide layer, and a thickness of the substrate is 0.25 millimeters to 0.35 millimeters.

[0026] The material of the substrate can be inorganic fibers such as glass fibers or organic fibers such as aramid fibers. The glass fibers or aramid fibers are woven to form a fiber cloth, the fiber cloth is arranged in a prepreg of epoxy resin to obtain a mixed layer, and a plurality of mixed layers are laminated to form the substrate according to the thickness requirement of the substrate. The glass fibers have high tensile strength, high elastic coefficient, and good rigidity. The aramid fibers have high strength and modulus, thereby improving the strength and modulus of the substrate. The polyimide has high tensile strength and elastic modulus, and thus, weaving the fiber cloth by using the polyimide material can reduce the thickness of the substrate, thereby reducing the cracking of the paint layer and reducing the overall thickness of the shell, which is more in line with actual use requirements.

[0027] The application further provides an electronic device, which includes the shell.

[0028] The shell and the electronic device provided in the embodiments of the present application, the shell comprises a substrate and a paint layer, and the paint layer is located on one side of the substrate along the thickness direction of the shell. When the shell is applied to the electronic device, the paint layer is located on the side of the substrate away from the interior of the electronic device. The thickness of the substrate is 0.25-0.4 mm, and the modulus of the substrate is 20-30 Gpa. Through such a design, the shell has high mechanical properties, the possibility of deformation of the substrate when subjected to impact can be reduced, the amount of deformation generated can be reduced, and thus the possibility of cracking of the paint layer arranged on the substrate can be reduced.

[0033] In order to better understand the technical solutions of the present application, the embodiments of the present application will be described in detail below with reference to the drawings.

[0034] It should be clear that the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0035] The terms used in the embodiments of the present application are only for the purpose of describing the specific embodiments, and are not intended to limit the present application. The singular forms "a", "an" and "the" used in the embodiments of the present application and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0036] With the development of technology, mobile phones, tablets, laptops and the like have become common electronic devices for people. Electronic devices usually include a shell, such as a back shell of the electronic device. The surface of the shell is usually provided with a paint layer, which can be provided with different textures for decorating the shell. However, the paint layer usually includes an ultra-violet (UV) layer provided with a texture pattern. However, the hardness of the UV layer is high, and the anti-deformation ability is poor. When the shell is subjected to external force, the paint layer is prone to cracking, which can easily cause damage to the paint layer and damage the user's experience.

[0037] In view of this, the embodiments of the present application provide a shell and an electronic device for reducing the possibility of damage to the paint layer of the shell.

[0038] As shown in Figure 1 The shell provided by the embodiments of the present application includes a substrate 1 and a paint layer 2. In the thickness direction of the shell, the paint layer 2 is located on one side of the substrate 1. When the shell is applied to an electronic device, the paint layer 2 is located on the side of the substrate 1 away from the inside of the electronic device. The thickness of the substrate 1 is 0.25 mm to 0.4 mm, and the modulus of the substrate 1 is 20 Gpa to 30 Gpa.

[0039] The thickness of the substrate 1 can be 0.25 mm, 0.26 mm, 0.27 mm, 0.28 mm, 0.29 mm, 0.30 mm, 0.31 mm, 0.32 mm, 0.33 mm, 0.34 mm, 0.35 mm, 0.36 mm, 0.37 mm, 0.38 mm, 0.39 mm, 0.40 mm, etc. The modulus of the substrate 1 can be 20.0 Gpa, 20.5 Gpa, 21.0 Gpa, 21.5 Gpa, 22.0 Gpa, 22.5 Gpa, 23.0 Gpa, 23.5 Gpa, 24.0 Gpa, 24.5 Gpa, 25.0 Gpa, 25.5 Gpa, 26.0 Gpa, 26.5 Gpa, 27.0 Gpa, 27.5 Gpa, 28.0 Gpa, 28.5 Gpa, 29.0 Gpa, 29.5 Gpa, 30.0 Gpa, etc.

[0040] The base 1 can soak the fiber cloth in the prepreg during processing to treat the fiber cloth. The prepreg can be epoxy resin. 5-10% titanium white powder, 10-15% toughening agent, 30-80% ceramic filler and 20-55% epoxy resin can be added to the epoxy resin. The content of titanium white powder can be 5%, 6%, 7%, 8%, 9%, 10%, etc. The content of the toughening agent can be 10%, 11%, 12%, 13%, 14%, 15%, etc. The content of the ceramic filler can be 30%, 35%, 40%, 45%, 50%, 55%, 60%, etc. The proportion of the epoxy resin can be 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, etc. After treatment, a mixed layer of fiber cloth and epoxy resin is obtained. In the mixed layer, the fiber content is 50-65%, and the epoxy resin prepreg content is 35-50%. The content of the fiber can be 50%, 51%, 52%, 53%, 54%, 55%, 56%, 57%, 58%, 59%, 60%, 61%, 62%, 63%, 64%, 65%. The content of the epoxy resin prepreg is 35%, 36%, 37%, 38%, 39%, 40%, 41%, 42%, 43%, 44%, 45%, 46%, 47%, 48%, 49%, 50%, etc. According to the thickness requirement of the base 1, the number of suitable treated fiber cloth is selected, and the fiber cloth is laminated to obtain the base 1.

[0041] When the modulus of the base 1 is small, the base 1 will deform greatly when the shell is hit or falls, and the paint layer 2 arranged on the base 1 will also deform with the base 1. The hardness of the paint layer 2 is high and the toughness is poor, so when the paint layer 2 deforms, it is easy to cause the paint layer 2 to crack and be damaged.

[0042] When the content of the epoxy resin is less than 20%, the overall adhesion of the prepreg will decrease, thereby causing the content of the epoxy resin prepreg in the mixed layer to decrease. When the content of the epoxy resin is higher than 55%, the content of the ceramic filler, titanium white powder and toughening agent will decrease due to the high content of the epoxy resin, thereby affecting the mechanical properties of the base 1. When the content of the titanium white powder and the toughening agent is low, the epoxy resin is easy to crack when the shell is hit or falls, and other structures are also easy to crack due to the epoxy resin, which is easy to cause damage to the base 1 and further cause the paint layer 2 to crack and be damaged. When the content of the titanium white powder and the toughening agent is high, the hardness and strength of the epoxy resin will decrease, that is, the epoxy resin is too soft and is more prone to deformation. When the shell is hit or falls, the base 1 is easy to deform and drive the paint layer 2 to deform due to the poor strength and hardness of the base 1, which causes the paint layer 2 to crack. The addition of the ceramic filler can improve the rigidity and strength of the base 1, and the deformation amount of the base 1 is reduced by 30-50%, thereby reducing the possibility of cracking of the paint layer 2.

[0043] In this way, the modulus of the substrate 1 can be increased by 10% to 15%, and the modulus of the substrate 1 can reach 20 GPa to 30 GPa, so that the shell has higher structural strength, and thus the deformation amount of the substrate 1 is smaller when the shell encounters collision, falling, etc., and thus the possibility of cracking of the paint layer 2 arranged on the surface of the substrate 1 can be reduced. At the same time, since the mechanical properties of the substrate 1 are improved, the thickness of the substrate 1 can be reduced within a certain range when the shell is manufactured, and thus the overall thickness of the shell can be reduced, which is beneficial to reduce the cost and facilitate the miniaturization design of electronic equipment.

[0044] As shown in FIG. 1, in a possible implementation, at least one filling layer 3 can be included, and the filling layer 3 is located on the side of the substrate 1 facing the paint layer 2. Figure 1

[0045] The filling layer 3 is located between the substrate 1 and the paint layer 2, and is used to improve the flatness of the surface of the substrate 1. In order to facilitate the arrangement of the paint layer 2 and improve the stability of the arrangement of the paint layer 2, and more in line with actual use requirements. At the same time, the filling layer 3 can have a certain color according to requirements, which is used to adjust the color of the shell, so as to meet the visual requirements of the shell.

[0046] In a possible implementation, the color of the filling layer 3 can be the same as the appearance color of the shell.

[0047] As shown in FIG. 1, in a possible implementation, the filling layer 3 is a polyurethane (PU) layer. The thickness of the filling layer 3 along the thickness direction of the shell is 0.6 mm to 1.2 mm. The thickness of the filling layer 3 can be 0.6 microns, 0.7 microns, 0.8 microns, 0.9 microns, 1.0 microns, 1.1 microns, 1.2 microns, etc. Figure 1 The polyurethane has good strength and toughness, and can reduce the possibility of cracking of the shell. By increasing the polyurethane layer, the surface of the substrate 1 can be filled and leveled, so as to improve the flatness and facilitate the arrangement of the paint layer 2.

[0048] In a possible implementation, the shell can include two filling layers 3, and each filling layer 3 is arranged in sequence along the height direction of the shell. The total thickness of the filling layer 3 can be 1.2 microns to 2.4 microns.

[0049] When the total thickness of the filling layer 3 is too small, the filling effect on the substrate 1 is poor, and the effect of strengthening the structure of the shell is poor. When the total thickness of the filling layer 3 is too large, the overall size of the shell will be affected.

[0050]

[0051] ​​In one possible implementation, the housing may consist of only one filler layer 3, the thickness of which is 0.6 micrometers to 1.2 micrometers.

[0052] In the solution provided by the embodiments of this application, by adjusting the formulation of epoxy resin prepreg, the overall mechanical properties of the substrate 1 can be improved, and the substrate 1 has better strength and modulus. The need for the reinforcing effect of the filler layer 3 is relatively low. Therefore, the solution provided by the embodiments of this application can only set one filler layer 3, which is beneficial to reduce the thickness of the shell.

[0053] like Figure 1 As shown, in one possible implementation, the housing includes a connecting layer 4 located between the substrate 1 and the filling layer 3, with the filling layer 3 connected to the substrate 1 via the connecting layer 4.

[0054] The connecting layer 4 can be an adhesive layer, so that the filling layer 3 can be set on the substrate 1, improving the stability of the filling layer 3 and better meeting the actual use requirements.

[0055] like Figure 1 As shown, in one possible implementation, the thickness of the connecting layer 4 is 8 to 15 micrometers. The thickness of the connecting layer 4 can be 8 micrometers, 9 micrometers, 10 micrometers, 11 micrometers, 12 micrometers, 13 micrometers, 14 micrometers, 15 micrometers, etc.

[0056] When the thickness of the connecting layer 4 is less than 8 micrometers, the thickness of the connecting layer 4 is too thin, resulting in poor connection performance and affecting the stability of the connection between the filler layer 3 and the substrate 1. When the thickness of the connecting layer 4 is greater than 15 micrometers, the large thickness of the connecting layer 4 will affect the overall size of the shell.

[0057] like Figure 1 As shown, in one possible implementation, the paint layer 2 includes a first texture layer 21, a second texture layer 22, and a buffer layer 23. The buffer layer is located between the first texture layer 21 and the second texture layer 22, wherein the first texture layer 21 is located on the side of the buffer layer 23 away from the substrate 1, and the second texture layer 22 is located on the side of the buffer layer 23 that resembles a texture.

[0058] In one possible implementation, the first texture layer 21 can be imprinted with a structure such as glittery sand, and the second texture layer 22 can be imprinted with an inner texture, which can be a streamlined or other textured structure. The buffer layer 23 can be set with a corresponding color according to the design requirements of the shell.

[0059] The first texture layer 21 is used to change the tactile feel of the shell, and the second texture layer 22 is used to change the visual effect of the shell. The buffer layer 23 can adjust the overall color of the shell. At the same time, the buffer layer 23 has good toughness and can play a cushioning role, thereby reducing the possibility of cracking of the first texture layer 21 and the second texture layer 22.

[0060] like Figure 1 As shown, in one possible implementation, the first texture layer 21 can be an ultraviolet layer, and the thickness of the first texture layer 21 along the thickness direction of the shell can be 18 micrometers to 25 micrometers. The thickness of the first texture layer 21 can be 18 micrometers, 19 micrometers, 20 micrometers, 21 micrometers, 22 micrometers, 23 micrometers, 24 micrometers, 25 micrometers, etc.

[0061] The first texture layer 21 can be a surface UV layer. By setting corresponding textures on the surface UV layer, the tactile sensation when a user uses an electronic device can be changed, thereby improving the user experience.

[0062] like Figure 1 As shown, in one possible implementation, the second texture layer 22 can be an ultraviolet layer, and the thickness of the second texture layer 22 along the thickness direction of the shell can be 20 micrometers to 25 micrometers. The thickness of the first texture layer 21 can be 20 micrometers, 21 micrometers, 22 micrometers, 23 micrometers, 24 micrometers, 25 micrometers, etc.

[0063] The second texture layer 22 can be a bottom UV layer. By setting the corresponding texture in the bottom UV layer, the visual effect of the electronic device casing can be changed, thereby improving the user experience.

[0064] like Figure 1 As shown, in one possible implementation, the buffer layer 23 can be a polyurethane layer with a thickness of 4 micrometers to 10 micrometers. The thickness of the buffer layer 23 can be 4 micrometers, 5 micrometers, 6 micrometers, 7 micrometers, 8 micrometers, 9 micrometers, 10 micrometers, etc.

[0065] By adding a PU layer, the toughness of paint layer 2 can be improved, reducing the possibility of paint layer 2 cracking and damage.

[0066] like Figure 2 As shown, in one possible implementation, the paint layer 2 may include a coating layer 24, which is located between the buffer layer 23 and the second texture layer 22 along the thickness direction of the housing.

[0067] By setting the coating layer 24, the gloss and brightness of the paint layer 2 can be improved, thereby improving the visual effect of the casing and enhancing the user experience.

[0068] In a possible implementation, the thickness of the coating layer 24 is 100 nm to 400 nm. The thickness of the coating layer 24 can be 100 nm, 120 nm, 140 nm, 160 nm, 180 nm, 200 nm, 220 nm, 240 nm, 260 nm, 280 nm, 300 nm, 320 nm, 340 nm, 360 nm, 380 nm, 400 nm, or the like. The material of the coating layer 24 can be a non-conductor metal vapor metallization (NCVD) film or an optical physical vapor deposition (OPVD) film.

[0069] When the thickness of the coating layer 24 is small, the coating layer 24 has a poor effect on the gloss and brightness. When the thickness of the coating layer 24 is large, the structural strength of the coating layer 24 is poor, and thus, when the coating layer 24 cracks, other structures of the paint layer 2 are easily affected, and the paint layer 2 is cracked and damaged.

[0070] In a possible implementation, the substrate 1 can be a glass fiber layer or an aramid layer, and the thickness of the substrate 1 is 0.3 mm to 0.4 mm. The thickness of the substrate 1 can be 0.31 mm, 0.32 mm, 0.33 mm, 0.34 mm, 0.35 mm, 0.36 mm, 0.37 mm, 0.38 mm, 0.39 mm, 0.40 mm, or the like.

[0071] The material of the substrate 1 can be inorganic fibers such as glass fibers or organic fibers such as aramid fibers. The glass fibers or aramid fibers are woven to form a fiber cloth, the fiber cloth is arranged in a prepreg of epoxy resin to obtain a mixed layer, and a plurality of mixed layers are laminated to form the substrate 1 according to the thickness requirement of the substrate 1. The glass fibers have high tensile strength, high elastic coefficient, and good rigidity. The aramid fibers have high strength and modulus, thereby facilitating the improvement of the strength and modulus of the substrate 1.

[0072] In a possible implementation, the substrate 1 can be a polyimide layer, and the thickness of the substrate 1 can be 0.25 mm to 0.35 mm. The thickness of the substrate 1 can be 0.25 mm, 0.26 mm, 0.27 mm, 0.28 mm, 0.29 mm, 0.30 mm, 0.31 mm, 0.32 mm, 0.33 mm, 0.34 mm, 0.35 mm, or the like.

[0073] The polyimide has high tensile strength and elastic modulus. The use of the polyimide material to weave the fiber cloth can facilitate the reduction of the thickness of the substrate 1, so that the cracking of the paint layer 2 is reduced, and the overall thickness of the shell is reduced, which is more in line with the actual use requirement.

[0074] In a possible implementation, the base 1 of the shell can be a glass fiber layer, the thickness of which is 0.4 mm, the prepreg can include 5% to 10% of titanium white, 10% to 15% of a toughening agent, and more than 30% of ceramic fillers, which can be alumina or other ceramic system fillers. Compared with the conventional scheme, the strength of the titanium white and the toughening agent in the prepreg is adjusted, and the ceramic fillers are added, so that the mechanical properties of the base 1 are improved. In the case of the same thickness of the shell, experiments are conducted on the scheme provided in the embodiment of the application and the conventional scheme, and the following Table 1 is obtained:

[0075] Scheme Shell thickness Monomer drop ball Whole machine marble drop Conventional scheme 1 0.5 mm 0.6 m (paint layer cracking) 1 m (paint layer cracking) Example 1 of the present application 0.5 mm 0.8 m (pass) 1.2 m (pass)

[0076] By adding titanium white, a toughening agent, and ceramic fillers in the prepreg, the strength of the base 1 can be increased while the toughness is improved, so that the strength of the shell is improved. The mechanical properties of the improved shell are obviously improved.

[0077] In a possible implementation, the base 1 of the shell is a glass fiber layer, and the paint layer 2 includes a film coating layer 24. The prepreg can include 5% to 10% of titanium white, 10% to 15% of a toughening agent, and 50% of ceramic fillers. Since the strength of the film coating layer 24 is poor and is more prone to cracking, in the embodiment including the film coating layer 24, the proportion of ceramic fillers in the prepreg can be increased, so as to further improve the mechanical properties of the shell. In the case of the same thickness of the shell, experiments are conducted on the scheme provided in the embodiment of the application and the conventional scheme, and the following Table 2 is obtained:

[0078] Table 2:

[0079]

[0080] In a possible implementation, the base 1 of the shell is an aramid layer, and the paint layer 2 includes a film coating layer 24. The prepreg can include 5% to 10% of titanium white, 10% to 15% of a toughening agent, and 40% of ceramic fillers.

[0081] The scheme provided in the embodiment of the application can improve the mechanical properties of the base 1 without increasing the thickness of the base 1, thereby reducing the possibility of cracking of the paint layer 2.

[0082] Based on the shell involved in each of the above embodiments, the embodiment of the application further provides an electronic device, which can be a mobile phone, a tablet computer, a notebook computer, or the like. The electronic device includes a shell, which can be a rear shell or the like of the electronic device. The shell can be the shell involved in any of the above embodiments, and the electronic device including the shell also has corresponding technical effects due to the technical effects of the shell, which will not be described herein.

[0083] The shell and the electronic device provided by the embodiments of the present application include a base 1 and a paint layer 2. In the thickness direction of the shell, the paint layer 2 is located on one side of the base. When the shell is applied to the electronic device, the paint layer 2 is located on the side of the base far from the inside of the electronic device. The thickness of the base 1 is 0.25-0.4 mm, and the modulus of the base 1 is 20-30 Gpa. Through such a design, the shell has high mechanical properties, the possibility of deformation of the base 1 when subjected to impact is reduced, the amount of deformation is reduced, and thus the possibility of cracking of the paint layer 2 arranged on the base 1 is reduced.
