Description

[0001] This application is a divisional application based on the invention with application number 202110910263.6, application date August 9, 2021, and title "Electronic Device and Method for Manufacturing Thereof". Technical Field

[0002] This application relates to the field of electronic device technology, and in particular to an electronic device and its manufacturing method. Background Technology

[0003] With the development of technology, electronic devices have become ubiquitous in people's lives. Mobile electronic devices, in particular, have seen rapid development due to their portability, practical functions, and ability to meet daily needs. Typical mobile electronic devices, such as mobile phones or tablets, often include camera modules for taking pictures. As users' demands for camera functionality and the aesthetics of electronic devices increase, camera modules and their metal decorative components are constantly being upgraded.

[0004] Taking mobile phones as an example, as the number and size of mobile phone cameras increase, the size of metal decorative parts is also getting larger. In order to make the decorative parts have a richer appearance, metal decorative parts can be assembled from multiple components. However, how to electrically connect the multiple components after disassembly is one of the problems to be solved. Summary of the Invention

[0005] This application provides an electronic device capable of electrically connecting disassembled decorative parts.

[0006] A first aspect of this application provides an electronic device, comprising at least: a housing, wherein the housing is provided with mounting holes;

[0007] It also includes: a first decorative element and a second decorative element, one end of the first decorative element engaging with the mounting hole, and the second decorative element being fitted onto the first decorative element;

[0008] One of the first and second decorative parts has a receiving groove for containing conductive adhesive, and the other of the first and second decorative parts has a conductive post inserted into the receiving groove and in contact with the conductive adhesive.

[0009] By creating a receiving groove in one of the first and second decorative parts, and by providing a conductive post extending into the receiving groove in the other of the first and second decorative parts, the conductive adhesive filling the receiving groove can fill the space between the contour surface of the conductive post and the groove wall. The cured conductive adhesive can effectively contact the conductive post and the receiving groove to reliably connect the first and second decorative parts electrically. Furthermore, the conductive adhesive and the conductive post occupy the space of the receiving groove, which requires relatively little space, thus facilitating the electrical connection between the first and second decorative parts in a limited space and enabling the electronic devices to be made thinner and lighter.

[0010] In one possible implementation, one end of the first decorative element passes through the mounting hole and is located outside the housing, while the other end of the first decorative element is located inside the housing and connected to the inner surface of the housing; the second decorative element is fitted onto the end of the first decorative element located outside the housing, and the outer edge of the second decorative element extends to the outer surface of the housing.

[0011] In one possible implementation, the first decorative element has the receiving groove, and the second decorative element has the conductive post. This helps ensure the strength of the second decorative element; for example, the second decorative element located on the outer side can have better resistance to deformation and breakage even if it is impacted by factors such as bumps or drops.

[0012] In one possible implementation, the first decorative element has a middle section connecting the two ends, the middle section being located in the mounting hole, and the receiving groove having at least a portion located in the middle section. Thus, the receiving groove occupies only a portion of the space of the mounting hole in the housing, thereby reducing or even eliminating the need to occupy space within the housing.

[0013] In one possible implementation, the receiving groove includes a through-slot extending through the first decorative element, the through-slot having a first open end facing into the housing, the first open end for the conductive adhesive to contact and cure with external air. In this way, on the one hand, the conductive adhesive can contact the air through the first open end, facilitating moisture absorption and curing, and ensuring reliable electrical connection between the first and second decorative elements; on the other hand, even if the back cover of the housing pushes up the second decorative element due to tolerances, resulting in a relatively small portion of the conductive post located in the receiving groove, the conductive adhesive can flow downwards under its own gravity and fill the space between the flange and the conductive post, thereby ensuring contact between the conductive adhesive and the conductive post, further ensuring reliable electrical connection between the first and second decorative elements.

[0014] In one possible implementation, the channel further has a second opening end opposite to the first opening end, wherein the opening area of ​​the first opening end is larger than the opening area of ​​the second opening end. This allows the first opening end to provide a larger contact area between the conductive adhesive and external air, facilitating faster moisture absorption and curing of the conductive adhesive.

[0015] In one possible implementation, the channel wall is provided with a flange protruding toward the conductive post; the flange is located on a portion of the channel wall closer to the outside of the housing. Thus, because the distance between the flange and the conductive post is relatively small, a smaller amount of conductive adhesive flows downward to the flange and fills the space between the flange and the conductive post, allowing the adhesive to contact the conductive post and the receiving channel, thereby ensuring reliable electrical connection between the first and second decorative parts. Additionally, it increases the contact area between the receiving channel and the conductive adhesive.

[0016] In one possible implementation, at least a portion of the sidewall of the channel is inclined; the inclined surface slopes away from the conductive post in the direction toward the interior of the housing. This increases the contact area between the receiving groove and the conductive adhesive, and a smaller amount of conductive adhesive flows downward to the flange and fills the space between the flange and the conductive post, allowing the adhesive to contact the conductive post and the receiving groove, thereby ensuring reliable electrical connection between the first and second decorative parts.

[0017] In one possible implementation, a cover plate is provided at the first opening end to seal the through groove. The cover plate serves to provide a sealing and protective function.

[0018] In one possible implementation, the end face of the first opening is recessed relative to the surface of the first decorative element facing into the housing to form a recess, and the cover plate is located in the recess. This helps to reduce or even avoid the space occupied by the cover plate inside the first decorative element, further facilitating the thinning and lightening of electronic devices.

[0019] In one possible implementation, the surface of the first decorative element facing the interior of the housing has a first region located at the edge, and a second region connected to the first region; the first region protrudes from the second region along the direction towards the interior of the housing; the sidewall of the through-slot located in the second region extends to be flush with another portion located in the first region. This allows the receiving groove to have a relatively larger receiving space, enabling it to accommodate more conductive adhesive, facilitating a larger contact area between the conductive adhesive and the receiving groove and conductive post, and improving the reliability of the electrical connection between the first and second decorative elements.

[0020] In one possible implementation, the opening of the receiving groove is located on the surface of the first decorative element facing the second decorative element; the groove wall of the receiving groove includes: a bottom wall and a side wall connected to the bottom wall, the end of the side wall away from the bottom wall forming the opening of the receiving groove.

[0021] In one possible implementation, at least a portion of the sidewall is an inclined surface; the inclined surface is inclined toward the conductive post in the direction toward the interior of the housing. This facilitates increasing the contact area between the receiving groove and the conductive adhesive, as well as increasing the thickness of the conductive adhesive, thereby improving the contact area between the conductive adhesive and the conductive post, and consequently improving the reliability of the electrical connection between the first decorative element and the second decorative element.

[0022] In one possible implementation, the outer surface of the intermediate section facing outwards from the housing is lower than the outer surface of the housing; the second decorative member has an extension section located in the mounting hole and abutting the intermediate section. Thus, the gap between the inner surface of the extension section facing the receiving groove and the corresponding surface of the intermediate section, as well as the gap between the wall of the mounting hole and the corresponding surfaces of the intermediate section and the extension section, can form a tortuous labyrinthine flow channel, which helps to reduce or even avoid conductive adhesive leakage.

[0023] In one possible implementation, the receiving slots comprise a plurality of spaced-apart slots. This improves the reliability of the electrical connection between the first decorative element and the second decorative element.

[0024] In one possible implementation, the conductive adhesive includes conductive silver paste. Conductive silver paste has strong conductivity and good thermal stability, which helps ensure the reliable electrical connection between the first decorative element and the second decorative element.

[0025] A second aspect of this application provides a method for manufacturing an electronic device, comprising:

[0026] A housing, a first decorative element, and a second decorative element are provided. The housing has a mounting hole, one of the first and second decorative elements has a receiving groove, and the other of the first and second decorative elements has a conductive post.

[0027] One end of the first decorative piece is fitted into the mounting hole of the housing;

[0028] The second decorative piece is fitted onto the first decorative piece, and the conductive post is inserted into the receiving groove so that the conductive post can contact the conductive adhesive filled in the receiving groove.

[0029] In one possible implementation, providing the first decorative element includes: forming an intermediate section in the first decorative element connecting the two ends, and providing the receiving groove in the intermediate section;

[0030] Accordingly, engaging one end of the first decorative element with the mounting hole of the housing includes:

[0031] One end of the first decorative element passes through the mounting hole and is located outside the housing, such that the middle section is located in the mounting hole;

[0032] The other end of the first decorative piece is connected to the inner surface of the housing.

[0033] In one possible implementation, providing the first decorative element includes:

[0034] A receiving groove with a first opening end and a second opening end opposite each other is formed in the middle section of the first decorative piece, so that the receiving groove is a through groove.

[0035] In one possible implementation, inserting the conductive post into the receiving groove so that the conductive post can contact the conductive adhesive filled in the receiving groove includes:

[0036] The conductive post located on the second decorative piece is inserted into the receiving groove from the second opening end;

[0037] Adjust the assembly, including the housing, the first decorative element, and the second decorative element, so that the first opening end faces upward;

[0038] Fill the receiving groove with conductive adhesive from the first opening end.

[0039] In one possible implementation, after filling the through groove with conductive adhesive from the first opening end, the method further includes:

[0040] After the conductive adhesive has cured upon contact with air from the first opening end, a cover plate is placed over the first opening end to seal it.

[0041] In one possible implementation, providing the first decorative element further includes:

[0042] A flange protruding toward the conductive post is formed on the portion of the wall of the receiving groove near the outside of the housing.

[0043] In one possible implementation, providing the first decorative element includes:

[0044] A receiving groove with a bottom wall and a side wall is formed in the middle section of the first decorative piece, such that the end of the side wall away from the bottom wall forms the opening of the receiving groove;

[0045] Accordingly, the second decorative piece is fitted onto the first decorative piece, and the conductive post is inserted into the receiving groove so that the conductive post can contact the conductive adhesive filled in the receiving groove, including:

[0046] Fill the receiving groove with conductive adhesive from the opening;

[0047] The second decorative piece is fitted onto the end of the first decorative piece located outside the housing, and the conductive post is inserted into the receiving groove from the opening so that the conductive post comes into contact with the conductive adhesive filled in the receiving groove.

[0088] The terminology used in the implementation section of this application is only for explaining specific embodiments of this application and is not intended to limit this application. The implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0089] The electronic device provided in this application embodiment may include, but is not limited to, mobile phones, tablets, laptops, ultra-mobile personal computers (UMPCs), handheld computers, walkie-talkies, netbooks, POS machines, personal digital assistants (PDAs), dashcams, security equipment, and other mobile or fixed terminals with shooting functions. For ease of description, this application embodiment uses a mobile phone as an example for illustration.

[0090] For ease of description, in the embodiments of this application, the direction facing the user when the electronic device is in working state is considered "front," and correspondingly, the direction away from the user when the electronic device is in working state is considered "rear." For example, the working state may include a state of displaying information to the user or a state of collecting information from the user. Taking a mobile phone as an example, when the mobile phone displays information to the user, the direction facing the user is considered "front," and the direction away from the user is considered "rear."

[0091] Figure 1 This is a three-dimensional structural diagram of the electronic device when viewed from front to back. Figure 2 This is a 3D structural diagram of the rear cover and camera trim components when viewed from the back. Please refer to... Figure 1 and Figure 2 As shown, the electronic device 100 provided in this application embodiment may include: a housing, which provides a structural frame for the electronic device 100. For example, as... Figure 2 As shown, the housing may include a connected mid-frame and a rear cover 20, with the rear cover 20 positioned relative to the rear side of the mid-frame. When the electronic device 100 has a display function, it may also have a display screen 10, positioned relative to the front side of the mid-frame. A circuit board and a battery may be disposed between the display screen 10 and the rear cover 20.

[0092] It is understood that in this embodiment, the housing is specifically described using a structure consisting of a middle frame and a back cover 20 as an example. The housing of the electronic device provided in this application includes, but is not limited to, the above-described structure. For example, in other embodiments, the housing may be a one-piece or separate shell made of metal or plastic, and its implementation process may be the same as or similar to that in the embodiment of this application.

[0093] The back cover 20 is typically a quadrilateral structure; for example, it can be a rounded rectangle. The back cover 20 can be made of metal, glass, plastic, or ceramic, etc. In this embodiment, the material of the back cover 20 is not limited.

[0094] The mid-frame may include a connected metal mid-plate and a frame. The frame surrounds the edge of the metal mid-plate, and the rear side of the frame can seal against the edge of the back cover. The frame may include a top frame, a bottom frame, a left frame, and a right frame, which together form a square ring-shaped frame. The frame can be made of metal or ceramic. The metal mid-plate is located on the front side of the back cover 20. The metal mid-plate can be made of aluminum, aluminum alloy, or magnesium alloy. The metal mid-plate and the frame can be snap-fitted, welded, glued, or integrally formed.

[0095] The circuit board and battery can be mounted on the metal mid-plate. For example, the circuit board and battery can be mounted on the side of the metal mid-plate facing the rear cover 20, or the circuit board and battery can be mounted on the side of the metal mid-plate facing the display screen 10. The metal mid-plate can have openings, and at least some components on the circuit board can be placed in the openings of the metal mid-plate.

[0096] The battery can be connected to the charging management module and the circuit board via the power management module. The power management module receives input from the battery and the charging management module, and supplies power to the processor, internal memory, external memory, display screen 10, camera module, and communication module. The power management module can also monitor parameters such as battery capacity, battery cycle life, and battery health status (leakage current, impedance, etc.). In some other embodiments, the power management module can also be located within the processor of the circuit board. In still other embodiments, the power management module and the charging management module can be housed in the same device.

[0097] The display screen 10 can be disposed on the front side of the bezel. The display screen 10 can be an organic light-emitting diode (OLED) display screen or a liquid crystal display (LCD) display screen. The display screen 10 can be electrically connected to the circuit board, and the display screen 10 can receive control signals from the circuit board and perform corresponding displays.

[0098] To achieve the shooting function, the electronic device 100 also includes at least one camera module and a flash (not shown in the figure). For example, the camera module may include a front-facing camera assembly and a rear-facing camera assembly. The number of front-facing camera assemblies can be one or more. The front-facing camera assembly can be positioned on the front side of the metal mid-plate facing the display screen 10. The number of rear-facing camera assemblies can also be one or more. The rear-facing camera assembly and the flash can be positioned on the rear side of the metal mid-plate facing the rear cover 20. The rear cover 20 has a through mounting hole for mounting portions of the flash and the rear-facing camera assembly. Of course, the placement of the front-facing and rear-facing camera assemblies can be, but is not limited to, those described above.

[0099] Taking a rear camera assembly as an example, the rear camera assembly may include: a lens, a filter, a bracket, a photosensitive element, a flexible board, and a connector, etc. The focal length of the rear camera assembly can be fixed or variable. When the focal length of the rear camera assembly is variable, the rear camera assembly may also include a focusing motor, which can be mounted to the bracket.

[0100] The filter can be configured according to functional requirements. For example, the filter can be an infrared cut-off filter (IRCF), which can filter out infrared light to prevent infrared light from entering the lens and affecting the image.

[0101] The photosensitive element can be a charge-coupled device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. Connectors are used to electrically connect the flexible board to the image signal processing (ISP) unit on the circuit board, and the ISP unit to the digital signal processing (DSP) unit. The ISP and DSP units can be individually mounted on the circuit board, or they can be integrated together on the circuit board.

[0102] When taking a picture, the shutter is opened, and light passes through the lens and through the filter to the photosensitive element. The photosensitive element converts the light signal into an electrical signal, which is then transmitted to the image processing unit (ISP) for processing via a flexible board and connector. The ISP converts the electrical signal into a digital image signal, which is then output to the digital processing unit (DSP) for further processing. The DSP converts the digital signal into image signals in standard formats such as RGB and YUV.

[0103] It is understood that the structures illustrated in the embodiments of this application do not constitute a specific limitation on the electronic device 100. In other embodiments of this application, the electronic device 100 may include more or fewer components than illustrated, or combine some components, or split some components, or have different component arrangements. The illustrated components may be implemented in hardware, software, or a combination of software and hardware. For example, the electronic device 100 may also include devices such as microphones.

[0104] Figure 3 Decorative components for the camera and back cover along Figure 2 The diagram shows the cross-sectional structure along the AA direction. Please refer to... Figure 2 and Figure 3 As shown, for aesthetic reasons and installation requirements, when a rear camera assembly is installed on the back cover 20, a camera decorative component 70 is typically installed at the mounting hole 21 on the back cover 20. The camera decorative component 70 can be made of metal and must be grounded to prevent static electricity.

[0105] Please refer to Figure 2 and Figure 3 As shown, the camera trim assembly 70 has a camera hole 71 for the rear camera assembly to take pictures. The rear camera assembly is disposed close to the camera trim assembly 70. For example, the lens of the rear camera assembly is fixedly disposed in the camera hole 71; or, the lens of the rear camera assembly is retractable in the camera hole 71; or, when in standby mode, the lens of the rear camera assembly is located inside the rear cover 20 of the electronic device 100 and does not extend into the camera hole 71, but when in operation, the lens can extend into the camera hole 71.

[0106] To achieve a richer aesthetic effect, the camera decorative component 70 can be assembled from multiple parts. These parts can be made of different materials, colors, or textures to achieve various visual effects.

[0107] For ease of description, in this embodiment, the direction towards the space enclosed by the display screen 10, the middle frame, and the back cover 20 is considered "inner," and the direction away from the space enclosed by the display screen 10, the middle frame, and the back cover 20 is considered "outer." Figure 3 For example, taking the back cover 20 as a reference, the right side of the back cover 20 is defined as the outer side of the back cover 20 (i.e., the outer side of the housing), and the left side of the back cover 20 is defined as the inner side of the back cover 20. Among these, Figure 3 The arrow Z in the diagram is used to indicate the outer side of the back cover 20, that is, the rear side of the electronic device 100.

[0108] Figure 4 For based on Figure 2 or Figure 3 A schematic diagram of the exploded structure. Please refer to... Figure 3 and Figure 4As shown, the camera decorative assembly 70 includes a first decorative element 72 and a second decorative element 73. The first decorative element 72 can be an annular structure, a circular annular structure, or a square annular structure. The hole in the middle of the first decorative element 72 can form a camera hole 71. The first decorative element 72 can have a stepped structure. One end of the first decorative element 72 can pass through the mounting hole 21 and be located on the outside of the back cover 20, while the other end of the first decorative element 72 can be located on the inside of the back cover 20 and connected to the inner surface of the back cover 20 through an adhesive layer 90. A light-transmitting sheet 80 can also be provided at the end of the first decorative element 72 that passes through the outside of the back cover 20, and the light-transmitting sheet 80 can also be bonded to the first decorative element 72 through the adhesive layer 90.

[0109] The second decorative element 73 can be a ring-shaped structure. A hole in the center of the second decorative element 73 allows one end of the first decorative element 72 to pass through. The second decorative element 73 can be located on the outside of the back cover 20. The second decorative element 73 can be fitted onto the outer side of the end of the first decorative element 72 located outside the back cover 20. The outer edge of the second decorative element 73 extends to the outer surface of the back cover 20, and the second decorative element 73 connects to the outer surface of the back cover 20. The second decorative element 73 can be a circular ring structure, or it can be a square ring structure.

[0110] Thus, the end of the first decorative piece 72 located outside the back cover 20 and the second decorative piece 73 can be made of different materials, colors, or engravings, thereby achieving different appearance effects. Of course, the end of the first decorative piece 72 located outside the back cover 20 and the second decorative piece 73 can also be made of the same material, color, and engraving.

[0111] The outer surface of the second decorative element 73 can be an inclined surface or a curved surface, which can enrich the appearance of the camera decorative component 70 and enhance the user's feel and improve the user experience.

[0112] In other embodiments, the second decorative element 73 can be decomposed into a plurality of annular decorative elements, which are sequentially nested around the outer surface of the end of the first decorative element 72 located outside the rear cover 20, and the outer edge of the outermost annular decorative element extends to the outer surface of the rear cover 20.

[0113] In other embodiments, the second decorative element 73 cooperates with the first decorative element 72 and is not bonded to the outer surface of the rear cover 20. The outer surface of the second decorative element 73 may be flush with the outer surface of the rear cover 20, or the outer surface of the second decorative element 73 may protrude outward from the outer surface of the rear cover 20, or the outer surface of the second decorative element 73 may be recessed inward relative to the outer surface of the rear cover 20.

[0114] In other embodiments, the first decorative element 72 cooperates with the second decorative element 73 but is not bonded to the outer surface of the rear cover 20. The inner surface of the first decorative element 72 may be flush with the inner surface of the rear cover 20, or the first decorative element 72 may be protruding inward from the inner surface of the rear cover 20, or the first decorative element 72 may be recessed outward relative to the inner surface of the rear cover 20.

[0115] The first decorative element 72 is also electrically connected to the second decorative element 73 via an electrical connection structure, and one of the first decorative element 72 and the second decorative element 73 is electrically connected to the grounding module of the electronic device 100. For example, the first decorative element 72 can be electrically connected to the grounding module provided on the circuit board. In this way, the static electricity of the first decorative element 72 and the second decorative element 73 can be discharged through the grounding module to prevent the static electricity of the first decorative element 72 and the second decorative element 73 from adversely affecting the rear camera assembly and other electronic components.

Figure 5b for Figure 5a Cross-sectional view at point DD. Figure 6 for Figure 5b An enlarged diagram of part B in the middle. Figure 5b and Figure 6 The arrow Z in the diagram is used to indicate the outer side of the back cover 20. Please refer to... Figure 5a , Figure 5b and Figure 6 As shown in the embodiment of this application, the electrical connection structure includes: a receiving groove 721, conductive adhesive 74, and a conductive post 731. The first decorative member 72 is provided with a receiving groove 721, which has an opening and is used to receive the conductive adhesive 74. The second decorative member 73 is provided with a conductive post 731 that can extend into the receiving groove 721 from the opening and contact the conductive adhesive 74.

[0117] In this way, after filling the receiving groove 721 with conductive adhesive 74, the uncured conductive adhesive 74 can fill the space between the contour surface of the conductive post 731 and the groove wall 7211 of the receiving groove 721. The cured conductive adhesive 74 can maintain effective contact with the conductive post 731 and the receiving groove 721 to achieve electrical connection. Furthermore, the conductive adhesive 74 and the conductive post 731 occupy the space of the receiving groove 721. The conductive adhesive 74 and the conductive post 731 are easily covered by the camera decorative component 70 itself, and the space requirement is relatively small. Thus, the electrical connection between the first decorative component 72 and the second decorative component 73 can be achieved in a relatively small space, which is conducive to the thinning of electronic devices.

[0118] In addition, it also helps to ensure the strength of the second decorative element 73. For example, the second decorative element 73 located on the outside of the rear cover 20 can have a good resistance to deformation and breakage even if it is impacted by factors such as bumps or drops.

[0119] The conductive post 731 can be columnar, for example, it can be a straight cylinder or a cone. The cross-section of the conductive post 731 can be circular, elliptical, or polygonal. The contour surface of the conductive post 731 includes a side surface 7311 and an end surface 7312 connected to the side surface. The end surface 7312 is the surface of the end of the conductive post 731 facing the receiving groove 721. When the conductive post 731 is a straight cylinder, the side surface 7311 is a cylindrical surface. When the conductive post 731 is a cone, the side surface 7311 is a conical surface.

[0120] Optionally, the conductive post 731 is a straight cylinder, and a guide surface 7313 is provided at the connection between the side surface 7311 and the end face 7312 of the conductive post 731. The size of the guide surface 7313 gradually decreases along the direction towards the receiving groove 721. Taking the conductive post 731 as a cylinder as an example, the diameter of the guide surface 7313 gradually decreases along the direction towards the receiving groove 721. The guide surface 7313 can be an inclined surface or an arc-shaped curved surface. In this way, during assembly, the guide surface 7313 can play a guiding role, which facilitates the rapid entry of the conductive post 731 into the receiving groove 721, thereby improving the assembly efficiency of the first decorative part 72 and the second decorative part 73.

[0121] In other embodiments, the receiving groove 721 can be disposed on the second decorative member 73. The conductive post 731 is disposed on the first decorative member 72. In order to enable the receiving groove 721 to accommodate more conductive adhesive 74 while maintaining the strength of the second decorative member 73, the receiving groove 721 can be disposed in a region of the second decorative member 73 with a relatively large thickness. For example, the opening of the receiving groove 721 is located on the inner surface of the second decorative member 73. Correspondingly, the conductive post 731 is located on the surface of the first decorative member 72 facing the second decorative member 73.

[0122] Figure 7 For the first decorative piece along Figure 5a A schematic diagram of the cross-sectional structure at point DD. Please refer to the diagram. Figure 7 As shown, and in combination Figure 6 , Figure 7 Arrow Z in the diagram is used to indicate the outer side of the back cover 20. For ease of description, the end of the first decorative piece 72 located on the outer side of the back cover 20 is designated as the first end 722, and the end of the first decorative piece located on the inner side of the back cover 20 is designated as the second end 724.

[0123] In this embodiment, the first decorative element 72 has an intermediate section 723 connecting the first end 722 and the second end 724, and the intermediate section 723 is located in the mounting hole 21. The intermediate section 723 protrudes outward relative to the second end 724, and also protrudes outward relative to the first end 722 in a direction away from the camera hole 71. The outer surface of the intermediate section 723 can be flush with the outer surface of the rear cover 20, or the outer surface of the intermediate section 723 can be lower inward than the outer surface of the rear cover 20, thus avoiding interference with the connection between the second decorative element 73 and the outer surface of the rear cover 20.

[0124] The first decorative element 72 can be in the form of multiple steps. For example, the first end 722, the middle section 723, and the second end 724 each constitute a step. Of course, the first decorative element 72 is not limited to including three steps; it can also include more than three steps. When the first decorative element 72 has a circular step structure, the outer diameter of the second end 724 is larger than the outer diameter of the middle section 723, and the outer diameter of the middle section 723 is larger than the outer diameter of the first end 722. When the first decorative element 72 has a square ring step structure, at least one of the long side and the wide side of the second end 724 is larger than the middle section 723, and at least one of the long side and the wide side of the middle section 723 is larger than the first end 722; for example, both the long side and the wide side of the second end 724 are larger than the middle section 723, and both the long side and the wide side of the middle section 723 are larger than the first end 722.

[0125] Please continue to refer to Figure 6 and Figure 7 As shown, the receiving groove 721 is located in the middle section 723. The conductive post 731 is located on the inner surface of the second decorative piece 73, and in the area opposite to the middle section 723. Thus, since the middle section 723 is located in the mounting hole 21, and the receiving groove 721 is located in the middle section 723, the receiving groove 721, the conductive post 731, and the conductive adhesive 74 occupy a portion of the space in the mounting hole 21, that is, the receiving groove 721, the conductive post 731, and the conductive adhesive 74 occupy a portion of the space in the back cover 20, which helps to reduce or even avoid occupying the space inside the back cover 20.

[0126] The following is combined with Figure 8 The implementation of the electrical connection between the first decorative element and the second decorative element in related technologies is described, and the beneficial effects of the embodiments of this application are analyzed by comparison.

[0127] Figure 8 This is a partial schematic diagram of the first decorative element 72a and the third decorative element 73a when viewed from the outside in. Please refer to... Figure 8As shown, in the related technology, the electrical connection between the first decorative element 72a and the second decorative element 73a is achieved by the following method: the electrical connection structure includes a conductive spring 78; the conductive spring 78 is disposed between the first decorative element 72a and the second decorative element 73a, thereby electrically connecting the first decorative element 72a and the second decorative element 73a.

[0128] The conductive spring contact 78 may have a fixing piece 781 and an elastic abutment piece 782. The fixing piece 781 can be connected to the first decorative piece 72, and the elastic abutment piece 782 can be connected to the second decorative piece 73. After the first decorative piece 72a and the second decorative piece 73a are assembled, the fixing piece 781 can be in surface contact with the first decorative piece 72a. The elastic abutment piece 782 undergoes elastic deformation due to the pressure of the second decorative piece 73a. Under the elastic deformation force of the elastic abutment piece 782, the elastic abutment piece 782 can firmly abut against the second decorative piece 73a, and the fixing piece 781 can be firmly in contact with the first decorative piece 72a. In order to prevent the second decorative piece 73a from tilting up under the elastic deformation force of the elastic abutment piece 782 and affecting the overall assembly quality, the second decorative piece 73a and the first decorative piece 72a can be fastened together by a fastening screw 79. In order to limit the offset of the conductive spring 78, a limiting hole is also required in the second decorative piece 73a so that the elastic abutment piece 782 can be locked in the limiting hole.

[0129] To avoid exposing the fastening screws 79 and conductive springs 78 and affecting the appearance of the electronic device 100, the fastening screws 79 and conductive springs 78 need to be placed in areas that can be covered. For example, the fastening screws 79 and conductive springs 78 can be placed in areas that can be covered by the back cover 20 or other components. Accordingly, the second decorative piece 73a needs to have an extension structure extending into the covered area. However, this will require more space for the installation of the conductive springs 78 and fastening screws 79, limiting the slimming and lightweight design of the electronic device 100.

[0130] Based on the above description, relative to Figure 8 Regarding the implementation methods shown in the related technologies, in this embodiment, the conductive adhesive 74 and conductive post 731 located in the receiving groove 721 can be shielded by the second decorative element 73 itself. This eliminates the need for anti-lifting fastening screws and additional structures to shield the fastening screws and conductive springs, thus requiring less space. This allows for electrical connection between the first decorative element 72 and the second decorative element 73 within a relatively small space, facilitating the thinning and lightening of electronic devices. Furthermore, since the conductive adhesive 74 and conductive post 731 can be shielded by the second decorative element 73 itself, the placement of the receiving groove 721 is more flexible, meaning the placement of the electrical connection structure is more flexible.

[0131] In other embodiments, the receiving groove 721 may also be located at the second end 724. The opening of the receiving groove 721 is located on the surface where the second end 724 connects to the inner surface of the rear cover 20. The rear cover 20 is provided with a clearance hole through which the conductive post 731 can pass, allowing the conductive post 731 to extend into the receiving groove 721. The conductive post 731 is located on the inner surface of the second decorative member 73.

[0132] In other embodiments, the receiving groove 721 may also be located at the first end 722. The opening of the receiving groove 721 may be located on the surface of the first end 722 facing the second decorative element 73. Correspondingly, the conductive post 731 is located on the wall of the hole in the middle of the second decorative element 73. However, the conductive adhesive 74 filling the receiving groove 721 is very easy to be exposed, which affects the appearance of the electronic device 100. Therefore, if this example is adopted, appearance optimization processing is also required.

[0133] In the embodiments of this application, please continue to refer to Figure 6 and Figure 7 As shown, the opening of the receiving groove 721 can be located on the outer surface of the middle section 723, that is, the opening of the receiving groove 721 can be located on the surface of the middle section 723 facing the second decorative member 73. The receiving groove 721 can extend inward by a predetermined length so that the receiving groove 721 can accommodate more conductive adhesive 74. In this way, the receiving groove 721 and the conductive adhesive 74, and the conductive adhesive 74 and the conductive post 731 can all have a larger contact area. On the one hand, this is beneficial to improving the reliability of the electrical connection between the first decorative member 72 and the second decorative member 73. On the other hand, the conductive adhesive 74 can also bond the first decorative member 72 and the second decorative member 73, which is beneficial to improving the reliability of the mechanical connection between the first decorative member 72 and the second decorative member 73. Of course, the extension length of the receiving groove 721 can be set according to actual needs, and this example does not specifically limit it; for example, the inward extension length of the receiving groove 721 can be equal to the thickness of the back cover 20, or the inward extension length of the receiving groove 721 can be equal to the thickness of the middle section 723.

[0134] Please continue to refer to Figure 6 and Figure 7 As shown, Figure 6 This is a partially enlarged schematic diagram of a cross-sectional view of the back cover 20, the first decorative element 72, and the second decorative element 73. Figure 7 This is a cross-sectional view of the first decorative element. Figure 6 and Figure 7 Sectional view direction ( Figure 5a (in the same direction as DD). During assembly, after the second decorative piece 73 is fitted onto the outer side of the first end 722 and the conductive post 731 is inserted into the receiving groove 721, the inner surface of the second decorative piece 73 facing the receiving groove 721 can be used to seal the gap between the receiving groove 721 and the conductive post 731, thereby playing a role in sealing and preventing leakage.

[0135] In one possible implementation, please refer to [link / reference]. Figure 6 and Figure 7 As shown, the receiving groove 721 can be a blind hole structure. The receiving groove 721 can be a circular hole structure, or a rectangular hole structure; of course, the receiving groove 721 can also be a hole structure of other shapes. The groove wall 7211 of the receiving groove 721 can include a bottom wall and side walls, with at least a portion of the side walls being inclined surfaces. This results in a larger area for the groove wall 7211, which is beneficial for increasing the contact area between the receiving groove 721 and the conductive adhesive 74.

[0136] Along the direction towards the inside of the rear cover 20, the inclined surface is inclined towards the conductive post 731. For example, the cross-section of the receiving groove 721 in the front-to-back direction can be trapezoidal, with parallel front and rear sides, and the length of the front side being less than the length of the rear side. This facilitates increasing the contact area between the receiving groove 721 and the conductive adhesive 74, and also facilitates increasing the thickness of the conductive adhesive 74, thereby increasing the contact area between the conductive adhesive 74 and the conductive post 731, and thus improving the electrical connection reliability between the first decorative element 72 and the second decorative element 73.

[0137] For example, the sidewalls of the receiving groove 721 are inclined surfaces from the opening to the bottom wall. Alternatively, the portion of the sidewalls of the receiving groove 721 near the bottom wall is inclined. Or, the sidewalls are all inclined surfaces along the circumference of the internal space of the receiving groove 721. Or, a portion of the sidewalls are inclined surfaces along the circumference of the internal space of the receiving groove 721. When there are multiple inclined surfaces, they are spaced apart. Taking the receiving groove 721 as a rectangular hole structure as an example, the wall of the receiving groove 721 corresponding to the long side of the rectangle is inclined, or the walls of the receiving groove 721 corresponding to both the long and wide sides of the rectangle are inclined.

[0138] Figure 9 This is a schematic diagram of the assembly process. Figure 9 Specifically, this is a schematic diagram of the second decorative component 73 being assembled with the first decorative component 72. Figure 9 The arrow Z in the diagram is used to indicate the outer side of the back cover 20. Please refer to... Figure 9 As shown, during assembly, the first end 722 of the first decorative piece 72 passes through the mounting hole 21 and is located outside the back cover 20, the second end 724 is connected to the inner surface of the back cover 20, and conductive adhesive 74 is filled into the receiving groove 721. The second decorative piece 73 is sleeved on the first end 722, and the conductive post 731 is inserted into the receiving groove 721 located in the middle section 723, with the conductive post 731 in contact with the conductive adhesive 74.

[0139] Figure 10a This is a schematic diagram of the structure of the back cover 20 and the first decorative element 72 when viewed from inside the electronic device. Figure 10b for Figure 10aCross-sectional view at the EE section. Figure 10b The arrow Z in the diagram is used to indicate the outer side of the back cover 20. Please refer to... Figure 10a and Figure 10b As shown, in another possible implementation, the receiving groove 721 can be disposed through the first decorative member 72. For example, the receiving groove 721 can be a through-slot penetrating the first decorative member 72. The through-slot can be a circular hole-like structure, or it can be a rectangular hole-like structure. Of course, the through-slot can also be a hole-like structure of other shapes. One opening of the receiving groove 721 is located on the surface of the first decorative member 72 facing the second decorative member 73, and the other opening of the receiving groove 721 can be located on the inner surface 725 of the first decorative member 72.

[0140] Figure 11 This is a schematic diagram of the structure when the receiving groove 721 is filled with conductive adhesive 74 with one opening facing upwards during the assembly process. Figure 11 The arrow Z in the diagram is used to indicate the outer side of the back cover 20. Please refer to... Figure 11 As shown, during assembly, the second decorative piece 73 is fitted onto the first end 722 of the first decorative piece 72, and the conductive post 731 is inserted into the receiving groove 721. The assembly consisting of the back cover 20, the first decorative piece 72, and the second decorative piece 73 can be adjusted so that the inner surface of the back cover 20 faces upward. Then, conductive adhesive 74 is filled into the receiving groove 721.

[0141] In this way, on the one hand, the conductive adhesive 74 can come into contact with air through the opening on the inner surface 725 of the first decorative part, which facilitates the moisture absorption and curing of the conductive adhesive 74. After curing, the conductive adhesive 74 does not have the problem of leakage and can ensure effective contact with the first decorative part 72 and the second decorative part 73, thereby ensuring the reliability of the electrical connection between the first decorative part 72 and the second decorative part 73. On the other hand, even if the back cover 20 pushes up the second decorative part 73 due to tolerance factors, resulting in a relatively small portion of the conductive post 731 located in the receiving groove 721, the conductive adhesive 74 can flow downward under its own gravity and fill the space between the receiving groove 721 and the conductive post 731, thereby ensuring that the conductive adhesive 74 can contact the conductive post 731, which helps to ensure the reliability of the electrical connection between the first decorative part 72 and the second decorative part 73.

[0142] In addition, during assembly, the inner surface of the second decorative part 73 can be used to seal the gap between the receiving groove 721 and the conductive post 731, thereby playing a role in sealing and preventing leakage.

[0143] Figure 12 The first decorative element 72 provided in one embodiment is along Figure 10a Cross-sectional view at point DD. Figure 12 Arrow Z in the diagram indicates the outer side of the rear cover 20. The receiving slot 721 may have a first opening end 7212 and a second opening end 7213. Please refer to... Figure 12 As shown, and in combination Figure 10a and Figure 11 The first opening end 7212 of the receiving groove 721 is further away from the second decorative member 73 than the second opening end 7213; for example, the first opening end 7212 is located on the inner surface 725 of the first decorative member. When the first decorative member 72 has a middle section 723, the second opening end 7213 can be located on the outer surface of the middle section 723; for example, the second opening end 7213 is located on the surface of the middle section 723 facing the second decorative member 73. The first opening end 7212 can be located on the inner surface of the second end 724, that is, the first opening end 7212 is located on the surface of the second end 724 away from the second decorative member 73, that is, the first opening end 7212 is located on the inner surface 725 of the first decorative member. In this way, the first opening end 7212 can allow the conductive adhesive 74 to come into contact with the outside air for moisture absorption and curing.

[0144] The opening area of ​​the first opening end 7212 can be larger than the opening area of ​​the second opening end 7213. In this way, the first opening end 7212 can provide a larger area for the conductive adhesive 74 to contact with the outside air, which is beneficial to accelerate the moisture absorption and curing of the conductive adhesive 74.

[0145] Figure 13a for Figure 11 An enlarged diagram of section C. Figure 13a The arrow Z in the diagram is used to indicate the outer side of the back cover 20. Please refer to... Figure 11 , Figure 12 and Figure 13a As shown, in one possible implementation, the receiving groove 721 is provided with a flange 7214 extending toward the conductive post 731. The distance between the flange 7214 and the conductive post 731 is less than the distance between the groove wall of other areas of the receiving groove 721 and the conductive post 731. The flange 7214 is located near the second opening end 7213. The flange 7214 can extend inward from the second opening end 7213 by a preset distance, the specific value of which can be set according to actual needs.

[0146] During assembly, when filling the receiving groove 721 with conductive adhesive 74, even if the rear cover 20 lifts the second decorative piece 73 due to tolerances, resulting in a relatively small portion of the conductive post 731 located in the receiving groove 721, the conductive adhesive 74 can flow downwards under its own gravity. Since the distance between the flange 7214 and the conductive post 731 is relatively small, a small amount of conductive adhesive 74 flows downwards to the flange 7214 and fills the space between the flange 7214 and the conductive post 731. This allows the conductive adhesive 74 to contact the conductive post 731 and the receiving groove 721, thereby ensuring the reliability of the electrical connection between the first decorative piece 72 and the second decorative piece 73. Furthermore, it can relatively increase the contact area between the receiving groove 721 and the conductive adhesive 74.

[0147] Figure 13b This is a partial structural diagram showing the back cover lifting up the second decorative element 73. Figure 13b The corresponding part and Figure 13a The corresponding C part is similar; Figure 13b The arrow Z in the diagram is used to indicate the outer side of the back cover 20. Please refer to... Figure 13b As shown, and in combination Figure 13a Furthermore, even when the back cover 20 lifts up the second decorative piece 73, resulting in a relatively small portion of the conductive post 731 being located in the receiving groove 721, a small amount of conductive adhesive 74 flows downward under its own gravity and fills the space between the flange 7124 and the conductive post 731, thereby ensuring that the conductive adhesive 74 can contact the conductive post 731, which helps to ensure the reliability of the electrical connection between the first decorative piece 72 and the second decorative piece 73.

[0148] Please continue to refer to Figure 13a As shown, to further improve the sealing effect, the second decorative member 73 can be provided with an extension section 732, which extends inward into the mounting hole 21 and connects with the intermediate section 723 in the mounting hole 21. A conductive post 731 is located on the extension section 732, extending inward from the extension section 732 toward the inner surface of the receiving groove 721. Thus, the inner surface of the extension section 732 toward the receiving groove 721 can be used to seal the gap between the conductive post 731 and the receiving groove 721, achieving a sealing and leak-proof effect. Furthermore, the gap between the inner surface of the extension section 732 toward the receiving groove 721 and the corresponding surface of the intermediate section, as well as the gap between the wall of the mounting hole 21 and the corresponding surfaces of the intermediate section 723 and the extension section 732, can form a tortuous labyrinthine flow channel. When the uncured conductive adhesive 74 flows in the labyrinthine flow channel, the frictional resistance generated by the viscosity of the conductive adhesive 74 helps to reduce or even prevent leakage of the conductive adhesive 74.

[0149] Figure 14 This is a schematic diagram of the structure of the first decorative element 72 when viewed from inside the electronic device. Please refer to... Figure 14 As shown, and in combination Figure 10a As shown in this embodiment, in order to facilitate a more compact layout of the components of the rear camera, the first decorative element 72 has a first region 727 located at the edge and a second region 728 connected to the first region 727, with the first region 727 protruding inward from the second region 728. This not only helps to ensure the strength of the first decorative element 72 but also helps to reduce the space occupied within the rear cover 20.

[0150] Figure 15 For the first decorative piece along Figure 14 A partial cross-sectional view along the FF direction. Figure 15 The arrow Z in the diagram is used to indicate the outer side of the back cover 20. Please refer to... Figure 14 and Figure 15 As shown, a portion of the receiving groove 721 can be located in the first region 727, and another portion can be located in the second region 728. In this case, the side wall of the receiving groove 721 located in the second region 728 extends inward to be flush with the side wall located in the first region 727. This gives the receiving groove 721 a relatively larger receiving space, which can accommodate more conductive adhesive 74. This facilitates a larger contact area between the conductive adhesive 74 and the receiving groove 721 and the conductive post 731, thereby improving the reliability of the electrical connection between the first decorative part 72 and the second decorative part 73. Of course, the receiving groove 721 can all be located in the first region 727.

[0151] Figure 16 This is a structural diagram showing the assembly of each cover plate 75 to the first decorative element 72. Figure 16 The sectional view direction is Figure 10a Middle EE direction; Figure 16 The arrow Z in the diagram is used to indicate the outer side of the back cover 20. Please refer to... Figure 16 As shown in the embodiment of this application, the first opening end 7212 of the receiving groove 721 can be covered with a cover plate 75. In this way, the cover plate 75 can play a sealing and protective role. The cover plate 75 can prevent external liquids and dust from entering the inside of the rear cover 20 from the receiving groove 721. The cover plate 75 can also insulate the conductive adhesive 74 from other components inside the rear cover 20, and can reduce the impact of heat generated by components such as circuit boards during operation on the conductive adhesive 74.

[0152] Figure 17 This is an exploded structural diagram of the back cover and camera trim components. Figure 17 The arrow Z in the diagram is used to indicate the outer side of the back cover 20. Please refer to... Figure 17 As shown, and in combination Figure 16 , Figure 10a As shown, the inner surface 725 of the first decorative element is partially recessed towards the outer side of the rear cover 20 to form a recess 726, and the first opening end 7212 of the receiving groove is located within the recess 726. The cover plate 75 can be located within the recess 726. The depth of the recess 726 can be equal to the thickness of the cover plate 75, or the depth of the recess 726 can be slightly less than the thickness of the cover plate 75, or the depth of the recess 726 can be slightly greater than the thickness of the cover plate 75. This helps to reduce or even avoid the space occupied by the cover plate 75 on the inner side of the first decorative element 72, further facilitating the thinning and lightening of electronic devices.

[0153] Among them, Figure 10a In the middle, the recess 726 located on the left side is not covered by a cover plate 75, and the conductive adhesive 74 can be seen from the inside of the first decorative part 72. The recess 726 located on the right side is covered by a cover plate 75, and the conductive adhesive 74 is covered by the cover plate 75.

[0154] Please continue to refer to Figure 10a and Figure 17 As shown in the embodiments of this application, the number of receiving slots 721 is multiple, which helps to further improve the reliability of the electrical connection between the first decorative member 72 and the second decorative member 73. When there are multiple receiving slots 721, the multiple receiving slots 721 can be arranged at intervals. Exemplarily, there can be two receiving slots 721, and the two receiving slots 721 are located on opposite sides of the first decorative member 72. This helps to improve the reliability of the electrical connection between the first decorative member 72 and the second decorative member 73, and also helps to reduce the space occupied by the receiving slots 721. Of course, the number of receiving slots 721 can be one, which helps to simplify the manufacturing cost.

[0155] Please continue to refer to Figure 17 As shown, during assembly, the second decorative piece 73 is fitted onto the first end 722 of the first decorative piece 72, and the conductive post 731 is inserted into the receiving groove 721. The assembly consisting of the back cover 20, the first decorative piece 72, and the second decorative piece 73 can then be adjusted so that the inner surface of the back cover 20 faces upwards. Then, conductive adhesive 74 is filled into the receiving groove 721. Figure 11 As shown; after the conductive adhesive 74 has cured, a cover plate 75 can be placed over the recessed portion 726, as shown. Figure 17 As shown.

[0156] In other embodiments, the receiving groove 721 can be an inclined hole-like structure. At least a portion of the sidewall of the receiving groove 721 is an inclined surface, sloping away from the conductive post 731 along the direction towards the inside of the rear cover 20. For example, the cross-section of the receiving groove 721 in the front-to-back direction is trapezoidal, with the front side of the trapezoid longer than the rear side. This increases the contact area between the receiving groove 721 and the conductive adhesive 74; and a smaller amount of conductive adhesive 74 flows downward to the flange 7214 and fills the space between the flange 7214 and the conductive post 731, allowing the conductive adhesive 74 to contact the conductive post 731 and the receiving groove 721, thereby ensuring reliable electrical connection between the first decorative element 72 and the second decorative element 73.

[0157] Of course, the receiving groove 721 can also be a straight hole structure penetrating the first decorative member 72. The cross-section of the receiving groove 721 along the front-back direction is rectangular. In this way, the processing difficulty of the receiving groove 721 is relatively low.

[0158] In this embodiment, the conductive adhesive 74 can be made of conductive silver paste. Conductive silver paste has strong conductivity and good thermal stability, which helps to ensure the reliability of the electrical connection between the first decorative component and the second decorative component. In other embodiments, the conductive adhesive 74 can also be made of gold-based conductive adhesive, copper-based conductive adhesive, or carbon-based conductive adhesive, etc.

[0159] This application also provides a method for manufacturing an electronic device. The structure and function of the electronic device can be referred to in the foregoing embodiments, and will not be repeated here.

[0162] S13. The second decorative piece is fitted onto the first decorative piece, and the conductive post is inserted into the receiving groove so that the conductive post can contact the conductive adhesive filled in the receiving groove.

[0163] In this embodiment, after filling the receiving groove with conductive adhesive, the uncured conductive adhesive can fill the space between the contour surface of the conductive post and the groove wall of the receiving groove. The cured conductive adhesive can effectively contact the conductive post and the receiving groove, reliably connecting the first decorative part and the second decorative part electrically. Furthermore, the conductive adhesive and the conductive post occupy the space inside the receiving groove, which facilitates the electrical connection between the first decorative part and the second decorative part in a relatively small space, and helps to make the electronic device thinner and lighter.
