Description

Technical Field

[0001] This disclosure relates to the field of housing technology for electronic devices, and more particularly to a housing assembly and its manufacturing method, and an electronic device. Background Technology

[0002] To enhance the aesthetics of electronic devices such as mobile phones, computers, and wearable devices, decorative elements are often covered onto the casing. These elements are then connected to the casing via a support frame, creating a casing assembly with a decorative finish, such as a PU leather battery cover with a support frame. However, the support frame makes the casing less streamlined. If the decorative elements are directly attached to the casing, the edges of the casing are typically not flat. During the die-cutting process, the edges of the decorative elements, lacking support from the casing, are prone to jagged edges and burrs, resulting in low die-cutting yield. Summary of the Invention

[0003] This disclosure provides a housing assembly and its manufacturing method, as well as an electronic device.

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

[0005] Shell body;

[0006] An exterior component is fitted to and covers the shell body; wherein the shell body and the exterior component each have a first part and a second part, the second part is connected to the edge of the first part, and the extension line of the thickness of the edge of the second part forms an acute angle with the surface of the first part, and the angle is greater than a first preset angle threshold.

[0007] In some embodiments, the acute angle between the extension line of the thickness of the second portion edge 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 exterior component is attached to the shell body via an adhesive layer.

[0010] In some embodiments, the material of the exterior component is a flexible material.

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

[0012] In some embodiments, the rigid material includes glass fiber;

[0013] The shell body is made of multiple layers of glass fiber pressed together.

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

[0015] An impact-resistant film is attached to the side of the exterior component facing the shell body.

[0016] According to a second aspect of the present disclosure, an electronic device is provided, comprising: a mid-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] The middle frame surrounds the second part of the outer appearance part of the housing assembly.

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

[0020] In some embodiments, the angle between the extension line of the thickness of the middle frame edge and the extension line of the thickness of the second part edge of the appearance component is less than a second preset angle threshold.

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

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

[0023] Positioning shell body;

[0024] The outer part is placed on the surface of the shell body and pressed together to obtain the pressed assembly;

[0025] The pressed component is punched to obtain the housing component as described in any one of claims 1-6.

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

[0027] The shell body is obtained by pressing multiple layers of glass fiber together.

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

[0029] Fix the shell body, and machine at least one positioning hole on the shell body;

[0030] The positioning shell body includes:

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

[0032] In some embodiments, pressing the outer component onto the surface of the shell body to obtain the pressed assembly includes:

[0033] Apply an adhesive layer to the surface of the exterior parts and / or the shell body;

[0034] The outer part and the shell body are pressed together based on the adhesive layer to obtain the pressed assembly.

[0035] In some embodiments, pressing the outer component to the shell body based on the adhesive layer to obtain the pressed assembly includes:

[0036] The outer part and the shell body are heat-pressed together using the adhesive layer to obtain a heat-pressed assembly;

[0037] The hot-pressed components are then cold-pressed to obtain the pressed components.

[0038] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects:

[0039] On the one hand, compared to a shell assembly formed by a shell body and an outer shell with a surrounding frame, the shell assembly of this disclosure does not require a surrounding frame. The outer shell is fitted and covers the surface of the shell body, improving the aesthetics and simplicity of the shell assembly. On the other hand, to facilitate assembly of the shell assembly into electronic devices, the extension line of the thickness of the second part of the edge of the shell body and the outer shell in this disclosure forms an acute angle with the surface of the first part. That is, the second part and the first part are not on the same plane. This allows the second part to be designed with a certain degree of bending, such as in the mid-frame of an electronic device, so that the edge of the second part is as close as possible to the edge of the mid-frame, improving the tightness of the shell assembly when assembled into the electronic device. Furthermore, since the second part and the first part are not on the same plane, during the manufacturing of the punched shell assembly, there is a problem where the edge of the outer shell is not supported by the shell body, resulting in burrs on the edge after punching. To address this, the acute angle between the extension line of the thickness of the second part's edge and the surface of the first part in this disclosure is greater than a first preset angle threshold, preventing the angle in the thickness direction of the second part's edge from being too sharp. This reduces the portion of the outer shell edge that is not supported by the shell body, thereby reducing burrs, serrations, etc., during punching and improving the yield of the shell assembly.

[0040] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0057] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0058] Figure 1 Example of a mobile phone with a battery cover in the related technology. Figure 1 , Figure 1 The battery cover consists of a polyurethane (PU) leather A01 and a fiberglass board A02 with a surrounding frame; by covering the PU leather A01 onto the fiberglass board A02 with a surrounding frame, the aesthetics of the mobile phone battery cover are improved.

[0059] Figure 2 Example of a mobile phone with a battery cover in the related technology. Figure 2 , Figure 2 The mobile phone includes a PU leather A01, a fiberglass board A02 with a frame, double-sided adhesive A03, and a mid-frame A04. The PU leather A01 covers the fiberglass board A02 with a frame to form a battery cover. The battery cover is fixedly connected to the mid-frame A04 of the mobile phone by the double-sided adhesive A03 and covers the battery in the mobile phone.

[0060] However, in related technologies, battery covers formed by covering a fiberglass board with a retaining frame and then covering it with PU leather are not visually clean due to the presence of the retaining frame. If the retaining frame is removed and the PU leather is directly adhered to a fiberglass board without a retaining frame, the edges of the fiberglass board are usually designed with curved surfaces for easy connection to the phone's frame. This causes the edges of the PU leather to lack support from the fiberglass board during die-cutting, resulting in jagged edges and burrs. Consequently, the PU leather and fiberglass board edges are not evenly bonded, leading to a low die-cutting yield for the phone battery cover. For example, Figure 3 The image shown illustrates an example of uneven adhesion between the PU leather and the fiberglass board edge. Figure 3 In the test, when the PU leather marked L1 is well bonded to the fiberglass board, there are gaps between the PU leather marked L2 and L3 and the fiberglass board, and the gaps are uneven, which is considered a failure in punching.

[0061] Figure 4 An example of a housing assembly shown in this disclosure embodiment. Figure 1 , Figure 4 In the middle, the housing assembly 100 includes:

[0062] Shell body 101;

[0063] The outer part 102 is fitted to the shell body 101 and covers the shell body 101; wherein the shell body 101 and the outer part 102 each 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 the 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 this embodiment of the disclosure, the housing component 100 may be the front or back cover of an electronic device, such as a mobile phone, tablet computer, or wearable device; for example, the housing component 100 is a mobile phone battery cover.

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

[0066] In some embodiments, the shell body 101 is formed by pressing multiple layers of glass fiber, thereby allowing for the selection of different numbers of glass fiber layers for pressing based on the thickness requirements of the shell body 101, resulting in shell bodies of different thicknesses.

[0067] In this embodiment, the outer part 102 is attached to the shell body 101 and covers the surface of the shell body 101. The material of the outer part 102 can be the rigid material mentioned above, or it can be a flexible material, such as genuine leather or PU leather, to protect the shell body 101. In addition, the aesthetics of the shell assembly 100 can be improved by the texture of the material of the outer part 102 itself, or by hot-printing different patterns on the outer part 102.

[0068] In this embodiment of the present disclosure, the outer part 102 is attached to the shell body 101 by means of adhesive layer bonding, snap-fit, screw fixing, etc., and the present disclosure does not limit this.

[0069] For example, the outer part 102 is attached to the shell body 101 by an adhesive layer, wherein the adhesive layer includes, for example, hot press adhesive, hydrogel, etc. Figure 5 An example of a housing assembly shown in this disclosure embodiment. Figure 2 , Figure 5In this embodiment, the housing assembly 100 includes a housing body 101, an exterior component 102, and an adhesive layer 103; the exterior component 102 is attached to the surface of the housing body 101 via the adhesive layer 103. It is understood that, compared to methods such as snap-fit ​​or screw fixing, the method of bonding with the adhesive layer 103 in this embodiment can improve the appearance simplicity of the exterior component 102.

[0070] In some embodiments, the housing assembly 100 further includes an impact-resistant film, such as a film made of polyester terephthalate (PET) or polyethylene (PE). The impact-resistant film is attached to the side of the outer component 102 facing the housing body 101, thereby effectively reducing damage to the housing body 101 from external impacts and protecting the internal components of the electronic device when the housing body is assembled into the electronic device.

[0071] In addition, the side of the shell body 101 facing away from the outer appearance part 102 in this embodiment may also be coated with foam adhesive to reduce friction between the shell assembly 100 and the covered object, such as reducing friction between the mobile phone battery cover and the battery, and reducing damage to the battery due to friction.

[0072] In this embodiment, both the shell body 101 and the outer appearance component 102 have a first portion 1011 and a second portion 1012, with the second portion 1012 connected to the edge of the first portion 1011. As described above, the outer appearance component 102 fits and covers the shell body 101; correspondingly, the first portion of the outer appearance component 102 fits and covers the first portion of the shell body 101, and the second portion of the outer appearance component 102 fits and covers the second portion of the shell body 101. The first portion 1011 and the second portion 1012 can be a plane, an inclined plane, a curved surface, etc.

[0073] In this embodiment of the present disclosure, the extension line of the thickness of the edge of the second portion 1012 of the shell body 101 and the outer appearance part 102 forms an acute angle with the surface of the first portion 1011, which is greater than a first preset angle threshold. Specifically, if the first portion 1011 is a plane or an inclined plane, the angle between the extension line of the thickness of the edge of the second portion 1012 and the surface of the first portion 1011 is the angle between the extension line of the thickness of the edge of the second portion 1012 and the plane containing the surface of the first portion 1011; if the first portion 1011 is a curved surface, the angle between the extension line of the thickness of the edge of the second portion 1012 and the surface of the first portion 1011 can be the angle between the extension line of the thickness of the edge of the second portion 1012 and the tangent line at the junction of the curved surface of the first portion 1011 and the second portion 1012.

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

[0075] In this embodiment of the disclosure, the first part 1011 of the shell body 101 and the outer part 102 is a plane. Therefore, when manufacturing the shell assembly 100, the plane on which the surface of the first part 1011 is located can be directly used as the reference plane. The extension line of the thickness of the edge of the second part 1012 is made at an acute angle to the reference plane and is greater than the first preset angle threshold, which improves the convenience and yield of manufacturing the shell assembly 100.

[0076] In this embodiment, the second part 1012 is curved. Compared to the second part 1012 being flat, when assembling the housing assembly 100 to an electronic device, such as assembling a PU battery cover to a mobile phone, a space can be formed between the mobile phone frame and the housing assembly 100 to accommodate the battery. At the same time, through the curved shape of the second part 1012, the edge of the outer part 102 (corresponding to the edge of the second part 1012) bends towards the frame, thereby reducing the distance between the edge of the outer part 102 and the frame, making the housing assembly 100 more tightly assembled with the electronic device.

[0077] In this embodiment of the present disclosure, the extension line of the thickness of the edge of the second portion 1012 of the shell body 101 and the outer appearance part 102 forms an acute angle with the surface of the first portion 1011 (corresponding to...). Figure 4 The angle is greater than a first preset angle threshold (α angle), meaning that the second part 1012 and the first part 1011 are not on the same plane, and the second part 1012 has a smaller degree of bending compared to the first part 1011. Therefore, the angle in the direction of the edge thickness of the second part 1012 (including the edge thickness of the outer 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 setting of the first preset angle threshold can be based on an angle that meets the punching yield requirements determined during multiple punching shell assembly manufacturing experiments.

[0078] Understandably, on the one hand, compared to a shell assembly formed by a shell body and an outer shell component with a surrounding frame, the shell assembly 100 of this embodiment does not require a surrounding frame. The outer shell component 102 fits and covers the surface of the shell body 101, improving the aesthetics and simplicity of the shell assembly 100. On the other hand, in order to facilitate the assembly of the shell assembly 100 to an electronic device (such as a mobile phone frame), the extension line of the thickness of the edge of the second part 1012 of the shell body 101 and the outer shell component 102 in this embodiment forms an acute angle with the surface of the first part 1011. That is, the second part 1012 and the first part 1011 are not on the same plane. Therefore, the second part 1012 can be designed with a certain degree of bending to fit the frame of the electronic device, so that the edge of the second part 1012 is as close as possible to the edge of the frame, improving the tightness of the assembly of the shell assembly 100 to the electronic device. Furthermore, since the second part 1012 and the first part 1011 are not on the same plane, when preparing the punched shell assembly 100, there are problems such as the edge of the outer part 102 not being supported by the shell body 101, resulting in fuzz on the edge after punching. In this embodiment, the acute angle between the extension line of the thickness of the edge of the second part 1012 and the surface of the first part 1011 is greater than the first preset angle threshold, so that the oblique angle in the direction of the edge thickness of the second part 1012 (including the edge thickness of the outer part 102 and the edge thickness of the shell body 101) is not too sharp. As a result, the portion of the edge of the outer part 102 that is not supported by the shell body 101 is smaller, thereby reducing the generation of fuzz, saw teeth, etc. during punching and improving the preparation yield of the shell assembly 100.

[0079] In some embodiments, the acute angle between the extension 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 this embodiment of the present disclosure, as described above, in order to better assemble the housing assembly 100 into the electronic device, the extension line of the thickness of the edge of the second part 1012 of the housing body 101 and the outer part 102 forms an acute angle with the surface of the first part 1011, and the angle is greater than a 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 oblique angle, the sharper the edge of the second part 1012, and the longer the distance of the outer part 102 beyond the end face of the housing body 101. During punching, the longer the distance of the outer part 102 beyond the end face of the housing body 101, that is, the more of the outer part 102 is not supported by the housing body 101, the more likely the punched outer part 102 will have problems such as serrations, burrs, and unstable dimensions because part of its lower end is not supported by the housing body 101.

[0081] Figure 6 This is a comparative example diagram showing different second-part oblique angles according to an embodiment of this disclosure. Figure 6The image shows shell assemblies with edge bevel angles of 35 degrees and 52 degrees for the shell body 101 and the second part 1012 of the outer appearance component 102, respectively; wherein the horizontal direction corresponds to the direction of the surface (e.g., plane) of the first part 1011 of the shell body 101 and the outer appearance component 102. Figure 6 It can be seen that when the angle is 35 degrees, the distance of the outer part 102 beyond the end face of the shell body 101 is l1; when the angle is 52 degrees, the distance of the outer part 102 beyond the end face of the shell body 101 is l2, and l1 is greater than l2. Therefore, the edge burrs generated during the punching of the shell assembly with an angle of 35 degrees are more than those generated during the punching of the shell assembly with an angle of 52 degrees. That is, the punching yield of the shell assembly with an angle of 35 degrees is lower than that of the shell assembly with an angle of 52 degrees.

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

[0083] Figure 7 This is an example diagram of an electronic device shown in an embodiment of this disclosure. Figure 7 In the middle, the electronic device 200 includes: 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 part 1012 of the outer part 102 of the housing assembly 100.

[0086] In this embodiment of the disclosure, the electronic device 200 includes a mid-frame 201 and a housing assembly 100. The mid-frame 201 is at least used for fixed connection with the housing assembly 100, and can also be used for fixedly mounting other devices built into the electronic device 200. For example, the electronic device 200 is a mobile phone, the mid-frame 201 is the mid-frame of the mobile phone, and the housing assembly 100 is the mobile phone battery cover.

[0087] In this embodiment, the frame 201 is fixedly connected to the shell body 101 of the housing assembly 100. The fixed connection can be achieved by snap-fitting, screw fixing, welding, bonding, or other methods. Since the outer appearance part 102 of the housing assembly 100 fits and covers the shell body 101, the outer appearance part 102 is fixed relative to the middle frame 201 by the shell body 101.

[0088] In this embodiment of the present disclosure, when the frame 201 is fixedly connected to the shell body 101 of the housing assembly 100, the frame 201 surrounds the second part 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 an integral whole in appearance. Compared with the shell body of the housing assembly being exposed or with a frame provided by the frame, the electronic device 200 of this embodiment of the present disclosure is equipped with a housing assembly 100 having an appearance part 102, and there is no need to provide a frame, which can improve the overall appearance and simplicity of the electronic device 200.

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

[0090] As described above, the middle frame 201 surrounds the second part 1012 of the outer appearance part 102 of the housing assembly 100. In this embodiment of the present disclosure, the distance between the middle frame 201 and the second part 1012 of the outer appearance part 102 is less than a preset distance threshold, that is, the gap between the middle frame 201 and the second part 1012 of the outer appearance part 102 is small, thereby making the gap between the electronic device 200 and the housing assembly 100 smaller in appearance and the assembly tighter.

[0091] In some embodiments, 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 exterior component 102 is less than a second preset angle threshold.

[0092] In this embodiment, since the middle frame 201 surrounds the second portion 1012 of the outer part 102 of the housing assembly 100, the distance between the middle frame 201 and the second portion 1012 of the outer part 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. This 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 outer part 102. Therefore, in this embodiment, 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 outer part 102 is less than a second preset angle threshold, which can further reduce the distance between the middle frame 201 and the second portion 1012 of the outer part 102, and improve the tighter assembly of the housing assembly 100 into the electronic device 200.

[0093] In this embodiment, 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 outer component 102. This design allows the edge of the middle frame 201 to fit perfectly against the edge of the second portion 1012 of the outer component 102, further enabling a tighter assembly of the housing assembly 100 to the electronic device 200.

[0094] Regarding the aforementioned housing assembly 100, this disclosure provides a method for manufacturing the housing assembly, such as... Figure 8 As shown, it includes the following steps:

[0095] S101, Positioning shell body;

[0096] S102. Place the outer part on the surface of the shell body and press it together to obtain the pressed assembly.

[0097] S103. The pressed component is punched to obtain the housing component 100.

[0098] In step S101, the shell body can be positioned by means of pressing, pulling or other methods using a fixture to reduce the displacement of the shell body.

[0099] In step S102, the outer appearance component is placed on the surface of the shell body and pressed together to obtain a pressed assembly. In the pressed assembly, the outer appearance component is fitted to and covers the shell body. Both the shell body and the outer appearance component have a first part and a second part, with the second part connected to the edge of the first part. It should be noted that the shell body and outer appearance component described in steps S101 and S102 have excess corner portions. These excess corner portions need to be punched off after step S103 to obtain the shell body and outer appearance component in the shell assembly 100.

[0100] In step S103, the pressed component is punched using a punching tool at a preset punching angle to obtain the housing component 100; as shown Figure 9 The diagram shows an example of punching a housing assembly after pressing the component. L4 represents the pressed component, and L5 represents the component obtained by punching the excess corner parts of the pressed component, which is the housing assembly 100.

[0101] Among them, the punching tool line diagram is as follows: Figure 10 As shown. Figure 10 In the process, the punching tools include 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 component to obtain the shell component 100.

[0102] The preset punching angle in this embodiment is related to the angle between the extension line of the thickness of the second part edge and the surface of the first part in the housing assembly to be prepared, so that the extension line of the thickness of the second part edge and the surface of the first part in the housing assembly 100 obtained after punching form an acute angle, 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 outer appearance component of the shell assembly as a plane, 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 second part edge in the shell assembly to be prepared and the surface of the first part; if a 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 second part edge in the shell assembly 100 to be prepared and the surface of the first part.

[0104] As can be seen from the foregoing, in order to reduce the problem of fuzz on the edges of the outer parts due to lack of support from the shell body, the embodiments of this disclosure are designed such that the acute angle between the extension line of the thickness of the second part of the edge of the shell assembly 100 obtained by punching and the surface of the first part is greater than the first preset angle threshold, so that the corners of the outer parts are not too sharp, and the portion of the outer parts that extends beyond the shell body is smaller. Therefore, during the punching process based on this angle, the outer parts are supported by the shell body, and less fuzz is generated after punching, which helps to improve the manufacturing yield of the shell assembly 100.

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

[0106] The shell body is obtained by pressing multiple layers of glass fiber together.

[0107] In the embodiments disclosed herein, such as Figure 11 The figure shown is an example of shell body preparation. Figure 11 In the diagram, L6 indicates a sheet made of multiple layers of glass fiber, and L7 indicates a shell body obtained by pressing multiple layers of glass fiber sheets together. The shell body can be obtained by hot pressing multiple layers of glass fiber together, or by hot pressing multiple layers of glass fiber together and then cold pressing them together.

[0108] The thickness of the shell body can be determined according to actual needs, generally ranging from 0.05 to 10 millimeters (mm), such as the common thickness of 0.25 to 0.6 mm for mobile phone battery covers. This thickness allows for the determination of the number of fiberglass sheets (thin sheets made of glass fiber). During shell body fabrication, complex structures can be created by locally stacking different numbers of fiberglass sheets and hot-pressing them onto the shell body. This method allows for adjusting the number of fiberglass sheets as needed, thereby increasing the flexibility of hot-pressing multiple fiberglass sheets to obtain the shell body and meeting different shell body size requirements.

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

[0110] Fix the shell body, and machine at least one positioning hole on the shell body;

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

[0112] In this embodiment of the disclosure, the shell body is fixed before positioning, and at least one positioning hole is machined on the shell body. The positioning hole can be machined on the shell body using specific equipment, such as a Computerized Numerical Control (CNC) device. The shape of the positioning hole can be circular, rectangular, etc., and this disclosure does not limit this.

[0113] Figure 12 This is a comparison illustration of the shell body before and after machining the positioning hole, as shown in an embodiment of this disclosure. Figure 12 In the diagram, L8 indicates the shell body without the locating holes, L9 indicates the shell body after the locating holes have been machined, and L10 indicates the locating holes; the locating holes include circular locating holes and rectangular locating holes. By determining the position and orientation of the shell body through the location of at least one locating hole, the accuracy of subsequent locating of the shell body based on the locating holes and punching of the locating shell body can be improved.

[0114] Furthermore, information such as the name and model of electronic devices can be machined onto the shell body using CNC equipment, but this disclosure does not limit this.

[0115] In some embodiments, pressing the outer component onto the surface of the shell body to obtain the pressed assembly includes:

[0116] Apply an adhesive layer to the surface of the exterior parts and / or the shell body;

[0117] The outer part and the shell body are pressed together based on the adhesive layer to obtain the pressed assembly.

[0118] In this embodiment, the adhesive layer is such as a hot-press adhesive or hydrogel. The adhesive layer is coated on the surface of the outer part and / or the shell body, and then the outer part and the shell body are pressed together based on the adhesive layer to obtain the pressed assembly. The pressing can be performed using a specific pressing device or mold.

[0119] Figure 13 This is an example diagram illustrating a mold-pressed exterior part and shell body according to an embodiment of the present disclosure. Figure 13 In the designation, M1 indicates the upper mold, M4 indicates the lower mold, and inside the mold, from top to bottom, the outer part (M5), the adhesive layer (M2), the thin sheet (M3) with the model number of the electronic device printed on it, and the shell body (M6) are placed sequentially. During the process of pressing the upper and lower molds together, the outer part and the shell body are pressed together by the adhesive layer.

[0120] It should be noted that, Figure 13 In the middle, the lower mold edge is provided with several protrusions. Correspondingly, the shell body, appearance parts, adhesive layer and thin sheet with the model number of the electronic device are machined with positioning holes. In order to make the upper mold and lower mold of the pressing mold, the protrusions pass through the corresponding positioning holes on the shell body, appearance parts, adhesive layer and thin sheet, and position and align the shell body, appearance parts, adhesive layer and thin sheet, thereby improving the alignment accuracy of the shell body, appearance parts, adhesive layer and thin sheet after pressing.

[0121] Figure 14 This is an example diagram showing the comparison between the exterior component and the shell body before and after pressing, according to an embodiment of this disclosure. L11 indicates the shell body without the exterior component pressed, and L12 indicates the assembly after the shell body and the exterior component are pressed. Because the exterior component covers the shell body, the assembly after pressing is more aesthetically pleasing.

[0122] It is understood that, in the embodiments of this disclosure, the appearance parts and the shell body are bonded together by an adhesive layer. Compared with methods such as snap-fitting and screw fixing, the adhesive layer bonding method in the embodiments of this disclosure can improve the appearance simplicity of the appearance parts.

[0123] In some embodiments, pressing the outer component to the shell body based on the adhesive layer to obtain the pressed assembly includes:

[0124] The outer part and the shell body are heat-pressed together using the adhesive layer to obtain a heat-pressed assembly;

[0125] The hot-pressed components are then cold-pressed to obtain the pressed components.

[0126] In this embodiment, using an adhesive layer, the outer part and the shell body are first hot-pressed together to obtain a hot-pressed assembly; after the hot-pressed assembly achieves the required tightness, the hot pressing is stopped, and the hot-pressed assembly is cold-pressed to obtain the pressed assembly. This embodiment, by using a hot-pressing followed by a cold-pressing method, can improve the stability of the pressed assembly.

[0127] In addition, desired textures, patterns, text, etc., can be hot-pressed onto the surface of the laminated components, such as... Figure 15 The image shown is a comparison example of a housing component before and after hot stamping. L13 indicates the unstamped exterior part, and L14 indicates the hot-stamped exterior part. By hot stamping different textures, patterns, and texts on the exterior parts, the recognizability and / or aesthetics can be improved.
