Description

Technical Field

[0001] The present disclosure relates to the technical field of housings of electronic devices, and in particular to a housing assembly and a preparation method thereof, and electronic devices. Background Art

[0002] In order to improve the aesthetics of electronic devices such as mobile phones, computers, and wearable devices, appearance parts are usually covered on the shell body, and the appearance parts are connected to the shell body through the surrounding frame of the shell body to obtain a shell assembly covered with appearance parts with decorative effects, such as a PU leather battery cover with a surrounding frame. However, the surrounding frame makes the appearance of the shell less concise, and if the appearance parts are directly attached to the shell body, since the edge of the shell body is usually not a plane, when punching the appearance parts and the shell body, the edge of the appearance parts cannot be supported by the shell body, which is prone to serrations, hair, etc., resulting in a low punching yield of the shell. Summary of the invention

[0003] The present disclosure provides a housing assembly and a preparation method thereof, and an electronic device.

[0004] According to a first aspect of an embodiment of the present disclosure, there is provided a housing assembly, comprising:

[0007] In some embodiments, the acute angle between an extension line of the thickness of the edge of the second portion and the surface of the first portion is greater than 45 degrees.

[0008] In some embodiments, the first portion is a plane; and / or the second portion is a curved surface.

[0009] In some embodiments, the appearance part is bonded to the shell body via an adhesive layer.

[0010] In some embodiments, the appearance member is made of a flexible material.

[0011] In some embodiments, the material of the shell body is a rigid material.

[0012] In some embodiments, the rigid material comprises fiberglass;

[0013] The shell body is formed by pressing together multiple layers of glass fibers.

[0014] In some embodiments, the housing assembly further comprises:

[0015] The impact-resistant film is attached to a surface of the appearance part facing the shell body.

[0016] According to a second aspect of an embodiment of the present disclosure, there is provided an electronic device, comprising: a middle frame, and the housing assembly described in the first aspect;

[0017] The middle frame is fixedly connected to the shell body of the shell assembly;

[0018] Wherein, the middle frame surrounds the second part of the appearance part of the shell assembly.

[0019] In some embodiments, the distance between the middle frame and the second portion of the appearance member is less than a preset distance threshold.

[0020] In some embodiments, an angle between an extension line of the thickness of the edge of the middle frame and an extension line of the thickness of the second portion of the edge of the appearance member is smaller than a second preset angle threshold.

[0021] In some embodiments, an extension line of the thickness of the edge of the middle frame is parallel to an extension line of the thickness of the second portion of the edge of the appearance member.

[0022] According to a third aspect of an embodiment of the present disclosure, there is provided a method for preparing a housing assembly, comprising:

[0023] Positioning shell body;

[0024] Placing the appearance part on the surface of the shell body and pressing it to obtain a pressed component;

[0025] The pressed assembly is punched to obtain the shell assembly according to any one of claims 1 to 6.

[0026] In some embodiments, the method further comprises:

[0027] Multiple layers of glass fibers are pressed together to obtain the shell body.

[0028] In some embodiments, the method further comprises:

[0029] Fixing the shell body, and processing at least one positioning hole on the shell body;

[0030] The positioning shell body comprises:

[0031] The shell body is positioned through the at least one positioning hole.

[0032] In some embodiments, placing the appearance part on the surface of the shell body for pressing to obtain a pressed assembly includes:

[0033] Coating an adhesive layer on the surface of the appearance part and / or the shell body;

[0034] The appearance component and the shell body are pressed together based on the adhesive layer to obtain the pressed component.

[0038] The technical solution provided by the embodiments of the present disclosure may have the following beneficial effects:

[0039] On the one hand, compared with the shell assembly formed by the shell body and the appearance part with the surrounding bone, the shell assembly of the embodiment of the present disclosure does not need the surrounding bone, and the appearance part is fitted to cover the surface of the shell body, thereby improving the appearance and simplicity of the shell assembly.

Further, since the second part and the first part are not in the same plane, when preparing the punching shell assembly, there are problems such as the edge of the appearance part not being supported by the shell body, resulting in the generation of hair on the edge after punching, etc., in this regard, the acute angle between the extension line of the thickness of the edge of the second part of the embodiment of the present disclosure and the surface of the first part is greater than the first preset angle threshold, so that the bevel angle in the thickness direction of the edge of the second part is not too sharp, so that the portion of the edge of the appearance part that is not supported by the shell body is small, thereby reducing the generation of hair, sawtooth, etc. during punching, and improving the preparation yield of the shell assembly.

[0040] It is to be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present disclosure. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0058] Figure 1 This is an example of a mobile phone with a battery cover in the related art. Figure 1 , Figure 1 In the embodiment, the battery cover includes a polyurethane (PU) skin A01 and a glass fiber board A02 with a surrounding frame. By covering the PU skin A01 on the glass fiber board A02 with a surrounding frame, the aesthetics of the mobile phone battery cover is improved.

[0059] Figure 2 This is an example of a mobile phone with a battery cover in the related art. Figure 2 , Figure 2 In the figure, the mobile phone includes a PU skin A01, a fiberglass board with a surrounding frame A02, a double-sided tape A03 and a middle frame A04 of the mobile phone; wherein the PU skin A01 covers the fiberglass board with a surrounding frame A02 to form a battery cover; the battery cover is fixedly connected to the middle frame A04 of the mobile phone by the double-sided tape A03 and covers the battery in the mobile phone.

[0060] However, in the related art, the battery cover formed by covering the PU skin on the fiberglass board with a frame is not visually concise due to the presence of the frame; and if the frame is removed and the PU skin is directly attached to the fiberglass board without a frame, the edge of the fiberglass board is usually designed as a curved surface for easy connection with the mobile phone middle frame, resulting in the edge of the PU skin being unable to obtain support from the fiberglass board when punching the PU skin and the fiberglass board, which is prone to jagged edges and hair, resulting in uneven adhesion between the PU skin and the fiberglass board edge, and a low punching yield of the mobile phone battery cover. Figure 3 The following is an example of uneven bonding between the PU leather and the edge of the fiberglass board. Figure 3 In the test, when the PU leather of the part marked by L1 fits well with the fiberglass board, there are gaps between the PU leather of the part marked by L2 and L3 and the fiberglass board, and the gaps are uneven, which is a case of unqualified punching.

[0061] Figure 4 An example of a housing assembly shown in an embodiment of the present disclosure Figure 1 , Figure 4 In the embodiment, the housing assembly 100 comprises:

[0062] Shell body 101;

[0063] The appearance piece 102 is fitted with the shell body 101 and covers the shell body 101; wherein, the shell body 101 and the appearance piece 102 both have a first part 1011 and a second part 1012, the second part 1012 is connected to the edge of the first part 1011, and an extension line of the thickness of the edge of the second part 1012 forms an acute angle with the surface of the first part 1011, and the angle is greater than a first preset angle threshold.

[0064] In the embodiment of the present disclosure, the housing assembly 100 may be a front housing, a rear housing, etc. of an electronic device including a mobile phone, a tablet computer, a wearable device, etc.; illustratively, the housing assembly 100 is a battery cover of a mobile phone.

[0065] The shell assembly 100 of the embodiment of the present disclosure includes a shell body 101 and an appearance part 102; wherein, the material of the shell body 101 can be a rigid material, such as glass fiber, carbon fiber, plastic, aluminum, sheet metal, steel, etc.; illustratively, the material of the shell body 101 is glass fiber, which has the advantages of good insulation, strong heat resistance, high corrosion resistance, etc.

[0066] In some embodiments, the shell body 101 is formed by laminating multiple layers of glass fibers, so that based on the thickness requirement of the shell body 101 , different layers of glass fibers can be selected for lamination to obtain shell bodies of different thicknesses.

[0067] The appearance part 102 of the embodiment of the present disclosure is fitted with the shell body 101, and the appearance part 102 covers the surface of the shell body 101; wherein, the material of the appearance part 102 can be the above-mentioned rigid material, and can also be a flexible material, such as genuine leather, PU leather, etc., for protecting the shell body 101; in addition, based on the texture presented by the material of the appearance part 102 itself, or by hot stamping different patterns on the appearance part 102, the aesthetics of the shell assembly 100 can be improved.

[0068] The appearance part 102 of the embodiment of the present disclosure is bonded to the shell body 101 by bonding with an adhesive layer, clamping, screw fixing, etc., and the present disclosure does not limit this.

[0069] Exemplarily, the appearance part 102 is attached to the shell body 101 via an adhesive layer, wherein the adhesive layer includes, for example, hot pressing adhesive, hydrogel, etc. Figure 5 An example of a housing assembly shown in an embodiment of the present disclosure Figure 2 , Figure 5In the embodiment, the housing assembly 100 includes a housing body 101, an appearance member 102, and an adhesive layer 103; the appearance member 102 is attached to the surface of the housing body 101 through the adhesive layer 103. It can be understood that, compared with the clamping, screw fixing and other methods, the bonding method of the adhesive layer 103 in the embodiment of the present disclosure can improve the simplicity of the appearance of the appearance member 102.

[0070] In some embodiments, the housing assembly 100 further includes an impact-resistant film, such as a film made of polyester resin (PET) material, polyethylene (PE) material, etc. The impact-resistant film is attached to the side of the appearance part 102 facing the housing body 101, thereby effectively reducing the damage to the housing body 101 caused by external impact force, and plays a protective role for the built-in components of the electronic device when the housing body is assembled to the electronic device.

[0071] In addition, the side of the shell body 101 of the embodiment of the present disclosure that is away from the appearance part 102 can also be coated with foam glue to reduce the friction between the shell assembly 100 and the covered object, such as reducing the friction between the mobile phone battery cover and the battery, reducing damage to the battery due to friction.

[0072] The shell body 101 and the appearance member 102 of the disclosed embodiment both have a first portion 1011 and a second portion 1012, and the second portion 1012 is connected to the edge of the first portion 1011. As can be seen from the foregoing, the appearance member 102 fits and covers the shell body 101, and correspondingly, the first portion of the appearance member 102 fits and covers the first portion of the shell body 101, and the second portion of the appearance member 102 fits and covers the second portion of the shell body 101. The first portion 1011 and the second portion 1012 can be planes, inclined surfaces, curved surfaces, etc.

[0073] In the embodiment of the present disclosure, the extended line of the thickness of the edge of the second part 1012 of the shell body 101 and the appearance part 102 forms an acute angle with the surface of the first part 1011 and is greater than the first preset angle threshold. If the first part 1011 is a plane or an inclined surface, the angle between the extended line of the thickness of the edge of the second part 1012 and the surface of the first part 1011 is the angle between the extended line of the thickness of the edge of the second part 1012 and the plane where the surface of the first part 1011 is located; if the first part 1011 is a curved surface, the angle between the extended line of the thickness of the edge of the second part 1012 and the surface of the first part 1011 may be the angle between the extended line of the thickness of the edge of the second part 1012 and the tangent line on the curved surface of the first part 1011 where the second part 1012 is connected.

[0074] In some embodiments, the first portion 1011 is a plane; and / or the second portion 1012 is a curved surface.

[0075] In the embodiment of the present disclosure, the first part 1011 of the shell body 101 and the appearance part 102 is a plane, so that when preparing the shell assembly 100, the plane where the surface of the first part 1011 is located can be directly used as the reference plane, and the extension line of the thickness of the edge of the second part 1012 can be made to form an acute angle with the reference plane and be greater than the first preset angle threshold, thereby improving the convenience and yield of preparing the shell assembly 100.

[0076] The second portion 1012 of the disclosed embodiment is a curved surface. Compared with the second portion 1012 being a flat surface, when the shell assembly 100 is assembled to an electronic device, such as assembling a PU leather battery cover to a mobile phone, an accommodating space can be formed between the middle frame of the mobile phone and the shell assembly 100 to accommodate the battery. At the same time, through the curved second portion 1012, the edge of the appearance part 102 (corresponding to the edge of the second portion 1012) is bent toward the middle frame, so that the distance between the edge of the appearance part 102 and the middle frame is smaller, so that the shell assembly 100 and the electronic device are assembled more tightly.

[0077] The extended line of the thickness of the edge of the second portion 1012 of the shell body 101 and the appearance member 102 of the embodiment of the present disclosure forms an acute angle (corresponding to Figure 4 In other words, the second portion 1012 is not on the same plane as the first portion 1011, and the second portion 1012 is less bent than the first portion 1011, so that the bevel angle in the direction of the edge thickness of the second portion 1012 (including the edge thickness of the appearance part 102 and the edge thickness of the shell body 101) is not too sharp. The first preset angle threshold is less than 90 degrees; the first preset angle threshold can be set based on the angle that meets the punching yield requirement determined during multiple preparation and punching shell assembly tests.

[0078] It is understandable that, on the one hand, compared to the shell assembly formed by the shell body and the appearance part having a rib, the shell assembly 100 of the embodiment of the present disclosure does not need a rib, and the appearance part 102 fits and covers the surface of the shell body 101, thereby improving the aesthetic and simple appearance of the shell assembly 100. On the other hand, in order to facilitate the assembly of the shell assembly 100 to the electronic device (such as the middle frame of a mobile phone), the extension line of the thickness of the edge of the second part 1012 of the shell body 101 and the appearance part 102 of the embodiment of the present disclosure forms an acute angle with the surface of the first part 1011, that is, the second part 1012 is not in the same plane as the first part 1011, so that the second part 1012 can be designed with a certain bend in accordance with the middle frame of the electronic device, so that the edge of the second part 1012 is as close to the edge of the middle frame as possible, thereby improving the assembly of the shell assembly 100 to the electronic device more tightly. Furthermore, since the second part 1012 and the first part 1011 are not in the same plane, when preparing the punched shell assembly 100, there is a problem that the edge of the appearance part 102 cannot be supported by the shell body 101, resulting in burrs on the edge after punching. In this regard, the acute angle between the extension line of the thickness of the edge of the second part 1012 of the embodiment of the present disclosure and the surface of the first part 1011 is greater than the first preset angle threshold, so that the bevel angle in the direction of the edge thickness of the second part 1012 (including the edge thickness of the appearance part 102 and the edge thickness of the shell body 101) is not too sharp, so that the portion of the edge of the appearance part 102 that is not supported by the shell body 101 is smaller, thereby reducing the generation of burrs, saw teeth, etc. during punching, thereby improving the preparation yield of the shell assembly 100.

[0079] In some embodiments, the acute angle between the extended line of the thickness of the edge of the second portion 1012 and the surface of the first portion 1011 is greater than 45 degrees.

[0080] In the disclosed embodiment, it can be known from the above that in order to better assemble the housing assembly 100 to the electronic device, the extension line of the thickness of the edge of the second part 1012 of the shell body 101 and the appearance part 102 forms an acute angle with the surface of the first part 1011, and the angle is greater than the first preset angle threshold, that is, there is a certain oblique angle in the thickness direction of the edge of the second part 1012. The smaller the inclination, the sharper the edge of the second part 1012, and the longer the distance that the appearance part 102 exceeds the end face of the shell body 101. During punching, the longer the distance that the appearance part 102 exceeds the end face of the shell body 101, that is, the more parts of the appearance part 102 that cannot be supported by the shell body 101, and the appearance part 102 punched out is prone to problems such as sawtooth, hair, and dimensional instability because part of the lower end is not supported by the shell body 101.

[0081] Figure 6 This is an example diagram showing a comparison of different second portion oblique angles in an embodiment of the present disclosure. Figure 6, the shell body 101 and the second part 1012 of the appearance part 102 are respectively shown with the shell assembly having the edge bevel angles of 35 degrees and 52 degrees; wherein the horizontal direction corresponds to the direction of the surface (such as the plane) of the shell body 101 and the first part 1011 of the appearance part 102. Figure 6 It can be seen that when the bevel angle is 35 degrees, the distance that the appearance part 102 exceeds the end face of the shell body 101 is l1; when the bevel angle is 52 degrees, the distance that the appearance part 102 exceeds the end face of the shell body 101 is l2, and l1 is smaller than l2. Therefore, the edge fuzz generated during punching of the shell component corresponding to the bevel angle of 52 degrees is more than the edge fuzz generated during punching of the shell component corresponding to the bevel angle of 35 degrees, that is, the punching yield of the shell component corresponding to the bevel angle of 52 degrees is lower than the punching yield of the shell component corresponding to the bevel angle of 35 degrees.

[0082] In order to further improve the punching yield, the angle (angle α) between the extension line of the thickness of the edge of the second part 1012 and the surface of the first part 1011 needs to be designed to be larger. Through multiple verifications and optimizations, when the angle α satisfies the range of 45°<α<90°, the punching yield will be greatly improved, thereby reducing the cost waste caused by low yield, helping to achieve the requirement of a simple appearance of the shell component while being suitable for mass production.

[0083] Figure 7 This is an example diagram of an electronic device shown in an embodiment of the present disclosure. Figure 7 In the embodiment, the electronic device 200 comprises: a middle frame 201 and the aforementioned housing assembly 100;

[0084] The middle frame 201 is fixedly connected to the shell body 101 of the shell assembly 100;

[0085] The middle frame 201 surrounds the second portion 1012 of the appearance component 102 of the housing assembly 100 .

[0086] In the embodiment of the present disclosure, the electronic device 200 includes a middle frame 201 and a housing assembly 100, wherein the middle frame 201 is at least used to be fixedly connected to the housing assembly 100, and can also be used to fix other components built into the electronic device 200. Exemplarily, the electronic device 200 is a mobile phone, the middle frame 201 is the middle frame of the mobile phone, and the housing assembly 100 is a battery cover of the mobile phone.

[0087] In the disclosed embodiment, the frame 201 is fixedly connected to the shell body 101 of the shell assembly 100, wherein the fixed connection may be by means of clamping, screw fixing, welding, bonding, etc. Since the appearance part 102 of the shell assembly 100 fits and covers the shell body 101, the appearance part 102 is fixed relative to the middle frame 201 through the shell body 101.

[0088] In the embodiment of the present disclosure, when the frame 201 is fixedly connected to the shell body 101 of the housing assembly 100, the middle frame 201 surrounds the second portion 1012 (not shown in the figure) of the appearance part 102 of the housing assembly 100, so that the appearance part 102 and the electronic device 200 form a whole in appearance. Compared with the method of exposing the shell body of the housing assembly or setting a surrounding frame through the middle frame, the electronic device 200 of the embodiment of the present disclosure is installed with the housing assembly 100 having the appearance part 102, and there is no need to set a surrounding frame, which can improve the overall appearance of the electronic device 200. Beauty and simplicity.

[0089] In some embodiments, the distance between the middle frame 201 and the second portion 1012 of the appearance member 102 is less than a preset distance threshold.

[0090] As can be seen from the foregoing, the middle frame 201 surrounds the second portion 1012 of the appearance part 102 of the shell assembly 100; in the embodiment of the present disclosure, the distance between the middle frame 201 and the second portion 1012 of the appearance part 102 is less than a preset distance threshold, that is, the gap between the middle frame 201 and the second portion 1012 of the appearance part 102 is smaller, so that the gap between the electronic device 200 and the shell assembly 100 is smaller in appearance, and the assembly is tighter.

[0091] In some embodiments, an angle between an extension line of the thickness of the edge of the middle frame 201 and an extension line of the thickness of the edge of the second portion 1012 of the appearance member 102 is smaller than a second preset angle threshold.

[0092] In the embodiment of the present disclosure, since the middle frame 201 surrounds the second portion 1012 of the appearance member 102 of the housing assembly 100, the distance between the middle frame 201 and the second portion 1012 of the appearance member 102 is the distance between the end face of the edge of the middle frame 201 and the end face of the second portion 1012, and the distance is proportional to the angle between the extension line of the thickness of the edge of the middle frame 201 and the extension line of the thickness of the edge of the second portion 1012 of the appearance member 102. Therefore, in the embodiment of the present disclosure, the angle between the extension line of the thickness of the edge of the frame 201 and the extension line of the thickness of the edge of the second portion 1012 of the appearance member 102 is less than the second preset angle threshold, which can further reduce the distance between the middle frame 201 and the second portion 1012 of the appearance member 102, and improve the assembly of the housing assembly 100 to the electronic device 200 to be more tightly.

[0093] In the embodiment of the present disclosure, the extension line of the thickness of the edge of the middle frame 201 is parallel to the extension line of the thickness of the edge of the second portion 1012 of the appearance member 102. With this solution, the edge of the middle frame 201 can be completely fitted with the edge of the second portion 1012 of the appearance member 102, further making the housing assembly 100 more tightly assembled to the electronic device 200.

[0094] With respect to the aforementioned housing assembly 100, the present disclosure provides a method for preparing the housing assembly, such as Figure 8 As shown, the following steps are included:

[0095] S101, positioning shell body;

[0096] S102, placing the appearance part on the surface of the shell body and pressing it to obtain a pressed assembly;

[0097] S103 , punching the pressed assembly to obtain the shell assembly 100 .

[0098] In step S101, the shell body can be positioned by pressing, pulling, etc. using a jig to reduce the displacement of the shell body.

[0099] In step S102, the appearance part is placed on the surface of the shell body and pressed to obtain a pressed assembly; wherein, in the pressed assembly, the appearance part is in contact with the shell body and the appearance part covers the shell body; the shell body and the appearance part both have a first part and a second part, and the second part is connected to the edge of the first part. It should be noted that the shell body and the appearance part described in steps S101 and S102 have redundant corners, and after executing step S103, the redundant corners need to be punched to obtain the shell body and the appearance part in the shell assembly 100.

[0100] In step S103, the pressed assembly is punched out by a punching tool at a preset punching angle to obtain a housing assembly 100; Fig. 9 An example diagram is shown of a shell assembly obtained by punching out a pressed assembly, wherein L4 indicates the pressed assembly, and L5 indicates an assembly obtained by punching out excess corner portions of the pressed assembly, namely, the shell assembly 100.

[0101] Among them, the punching tool line diagram is as follows Fig.10 shown. Fig.10 In the embodiment, the punching tool includes an upper punching tool, a lower punching tool, a left punching tool and a right punching tool, which punch the four sides of the pressed assembly respectively to obtain the shell assembly 100.

[0102] The preset punching angle in the embodiment of the present disclosure is related to the angle between the extension line of the thickness of the edge of the second part and the surface of the first part in the shell component to be prepared, so that the extension line of the thickness of the edge of the second part of the shell component 100 obtained after punching forms an acute angle with the surface of the first part, and the angle is greater than the first preset angle threshold.

[0103] Taking the surface of the shell body and the first part of the appearance part of the shell assembly as a plane as an example, if the surface of the first part is used as the punching reference plane, the preset punching angle is consistent with the angle between the extension line of the thickness of the edge of the second part and the surface of the first part in the shell assembly to be prepared; if the plane perpendicular to the surface of the first part is used as the punching reference plane, the preset punching angle is complementary to the angle between the extension line of the thickness of the edge of the second part and the surface of the first part in the shell assembly 100 to be prepared.

[0104] As can be seen from the foregoing, in order to reduce the problem that the edge of the appearance part cannot be supported by the shell body, resulting in fuzz on the edge after punching, the embodiment of the present disclosure is designed so that the acute angle between the extension line of the thickness of the edge of the second part of the shell assembly 100 obtained by punching and the surface of the first part is greater than a first preset angle threshold, so that the corners of the appearance part are not too sharp, and the part of the edge of the appearance part that protrudes beyond the shell body is smaller. When the appearance part is punched based on this angle, it is supported by the shell body, and less fuzz is generated after punching, which helps to improve the preparation yield of the shell assembly 100.

[0105] In some embodiments, the method further comprises:

[0106] Multiple layers of glass fibers are pressed together to obtain the shell body.

[0107] In the embodiments of the present disclosure, Fig.11 An example of shell body preparation is shown in FIG. Fig.11 Among them, L6 indicates a thin sheet made of multiple layers of glass fiber, and L7 indicates a shell body obtained by pressing multiple layers of glass fiber thin sheets together; wherein the shell body can be obtained by hot pressing multiple layers of glass fiber together; or the shell body can be obtained by first hot pressing multiple layers of glass fiber together and then cold pressing them together.

[0108] Among them, the thickness of the shell body can be determined according to actual needs, generally 0.05 to 10 millimeters (mm), such as the common thickness of the mobile phone battery cover 0.25 to 0.6 mm; thus, the number of glass fiber sheets (sheets made of glass fiber) can be determined based on the thickness of the shell body. When preparing the shell body, a complex structure can be hot-pressed on the shell body by locally superimposing different numbers of glass fiber sheets. Through this solution, the number of glass fiber sheets can be adjusted based on needs, thereby improving the flexibility of obtaining the shell body after hot pressing multiple glass fiber sheets to meet different shell body size requirements.

[0109] In some embodiments, the method further comprises:

[0110] Fixing the shell body, and processing at least one positioning hole on the shell body;

[0111] The positioning of the shell body comprises: positioning the shell body through the at least one positioning hole.

[0112] In the embodiment of the present disclosure, before positioning the shell body, the shell body is fixed and at least one positioning hole is processed on the shell body; wherein the positioning hole can be processed on the shell body by a specific device, such as by a computerized numerical control (CNC) device. The shape of the positioning hole can be circular, rectangular, etc., which is not limited in the present disclosure.

[0113] Fig.12 This is a comparison diagram of a shell body before and after machining a positioning hole according to an embodiment of the present disclosure. Fig.12 In the figure, L8 indicates the shell body without positioning holes, L9 indicates the shell body after positioning holes are processed, and L10 indicates the positioning holes; the positioning holes include circular positioning holes and rectangular positioning holes. The position and direction of the shell body can be determined by the position of at least one positioning hole on the shell body, which helps to improve the accuracy of subsequent positioning of the shell body based on the positioning holes and punching of the positioned shell body.

[0114] In addition, the name, model, and other information of the electronic device may be processed on the shell body by means of CNC equipment, but the present disclosure does not limit this.

[0115] In some embodiments, placing the appearance part on the surface of the shell body for pressing to obtain a pressed assembly includes:

[0116] Coating an adhesive layer on the surface of the appearance part and / or the shell body;

[0117] The appearance component and the shell body are pressed together based on the adhesive layer to obtain the pressed component.

[0118] In the embodiment of the present disclosure, the adhesive layer is such as a hot-press adhesive, a hydrogel, etc.; the adhesive layer is coated on the surface of the appearance part and / or the shell body, and then the appearance part and the shell body are pressed together based on the adhesive layer to obtain a pressed component. The pressing can be performed by a specific pressing device or mold.

[0119] Fig.13 This is an example diagram of an embodiment of the present disclosure showing an appearance part and a shell body pressed together by a mold. Fig.13 In the figure, M1 marks the upper mold of the mold, M4 marks the lower mold of the mold, and the appearance part marked by M5, the adhesive layer marked by M2, the sheet with the model of the electronic device printed on it marked by M3, and the shell body marked by M6 are placed in the mold from top to bottom. In the process of pressing the upper mold and the lower mold of the mold, the appearance part and the shell body are pressed together through the adhesive layer.

[0120] It should be noted that Fig.13 In the embodiment, a plurality of protrusions are arranged on the edge of the lower mold, and correspondingly, positioning holes are processed on the shell body, the appearance part, the adhesive layer and the sheet engraved with the model of the electronic device, so that before the upper mold and the lower mold of the pressing mold are pressed, the protrusions are passed through the corresponding positioning holes on the shell body, the appearance part, the adhesive layer and the sheet to position and align the shell body, the appearance part, the adhesive layer and the sheet, thereby improving the alignment accuracy of the shell body, the appearance part, the adhesive layer and the sheet after pressing.

[0121] Fig.14 This is an example comparison diagram of an appearance part and a shell body before and after being pressed together, shown in an embodiment of the present disclosure, wherein L11 identifies the shell body without the appearance part pressed together, and L12 identifies the assembly after the shell body and the appearance part are pressed together. Because the appearance part covers the shell body, the assembly after pressing together is more beautiful in appearance.

[0122] It can be understood that the embodiment of the present disclosure laminates the appearance part and the shell body through the adhesive layer. Compared with the methods of clamping, screw fixing, etc., the embodiment of the present disclosure can improve the simplicity of the appearance of the appearance part by bonding through the adhesive layer.

[0123] In some embodiments, the method of laminating the appearance component and the shell body based on the adhesive layer to obtain the laminating assembly includes:

[0124] Using the adhesive layer to heat-press the appearance component and the shell body to obtain a heat-pressed assembly;

[0125] The hot pressed assembly is cold pressed to obtain the pressed assembly.

[0126] In the disclosed embodiment, the appearance part and the shell body are firstly hot pressed by using the adhesive layer to obtain a hot pressed assembly; and after the hot pressed assembly obtains the required tightness of pressing, the hot pressed assembly is stopped and the hot pressed assembly is cold pressed to obtain a pressed assembly. The disclosed embodiment can improve the stability of the pressed assembly by first hot pressing and then cold pressing.

[0127] In addition, the required texture, pattern, text, etc. can be stamped on the surface of the pressed components, such as Fig.15 An example comparison diagram of a shell component before and after hot stamping is shown, wherein L13 indicates an unhot stamped appearance part, and L14 indicates an appearance part after hot stamping. By hot stamping different textures, patterns, texts, etc. on the appearance parts, the recognition and / or aesthetics can be improved.
