[0002] As electronic devices become more and more popular, consumers have higher and higher requirements for all aspects of smartphones, and the sophistication of appearance has become a very important factor.

[0003] In order to ensure the exquisite appearance of electronic devices, it is necessary to set decorative parts in the exposed connection holes of the electronic devices (such as USB connection holes, headphone connection holes, etc.). However, it is difficult to process decorative parts at present, resulting in high costs. Utility Model Content

[0004] The purpose of the present application is to provide a decorative part, a housing assembly and an electronic device, so as to reduce the processing difficulty and processing cost of the decorative part.

[0005] In a first aspect of the present application, a housing assembly for an electronic device is provided, comprising a housing, a decorative member and a connector. The housing is provided with a housing cavity, and a first connecting hole penetrating the housing is provided on the housing. The decorative member comprises a decorative portion and an extension portion. The decorative portion is located in the first connecting hole and is arranged around the inner wall of the first connecting hole. A second connecting hole is provided on the decorative portion. The second connecting hole penetrates the decorative portion along the axis direction of the first connecting hole. The extension portion is located in the housing cavity and is arranged around the periphery of the second connecting hole, and the extension portion is connected to the decorative portion. The connector is located in the housing cavity. The extension portion is connected to the housing through the connector.

[0006] In the related art, after the decorative part is initially processed, the decorative part is inserted into the opening of the frame, and then the decorative part and the frame are limited by a mold. Then, the injection molding is performed to form an injection molded part, and the decorative part and the frame are fixed by the injection molded part. In order to ensure the positioning accuracy of the decorative part and the frame during injection molding, the precision of the injection molding equipment needs to be high, which makes the processing cost high.

[0007] In a shell assembly for an electronic device provided by the present application, the decorative piece includes a decorative portion and an extension portion. During assembly, the decorative portion of the decorative piece is extended into the first connecting hole, which can conceal the inner wall of the first connecting hole to improve the appearance of the first connecting hole. The extension portion is connected to the shell by a connector, so that the position of the decorative piece and the shell is relatively fixed. In this way, the decorative piece can be assembled with the shell separately, and there is no need to injection mold the decorative piece and the shell together. The process is relatively simple, which can reduce the processing difficulty and processing cost of the decorative piece. In addition, by disassembling the connector, the decorative piece and the shell can be separated, which is convenient for disassembly and maintenance of the decorative piece, and also convenient for replacing decorative pieces of different colors and materials.

[0008] In an optional embodiment, the shell includes a bottom shell and a side portion. The side portion is arranged around the periphery of the bottom shell. The first connecting hole is opened in the side portion and passes through the side portion. The bottom shell and the side portion surround a receiving cavity. The extension portion includes a side plate and a fixing plate. The side plate is arranged around the periphery of the second connecting hole and surrounds a third connecting hole connected to the second connecting hole. Along the axial direction of the first connecting hole, the third connecting hole passes through the side plate. The fixing plate is located on the side of the side plate away from the decorative portion, and the fixing plate is connected to the bottom shell through a connecting member.

[0009] At this time, after the decorative part of the decorative piece is extended into the first connecting hole opened on the side, the fixing plate of the extension part and the bottom shell can be relatively fixed through the connecting piece, thereby making the decorative piece relatively fixed to the bottom shell. In the case where the size of the side away from the bottom shell is small, by connecting the fixing plate to the bottom shell, the operating space on both sides of the tooling can be larger during installation, which is convenient for installing the connecting piece on the extension part and the shell. It can further reduce the processing difficulty and processing cost of the decorative piece. In addition, the second connecting hole is connected to the third connecting hole, and the third connecting hole passes through the side plate, thereby ensuring that the components in the accommodating cavity can pass through the third connecting hole and be arranged in the second connecting hole, and connected to the external device that also extends into the second connecting hole.

[0010] In an optional embodiment, the connector is a threaded connector, which passes through the fixing plate and is threadedly connected to the bottom shell. The threaded connection is convenient for installation and removal. When the threaded connector passes through the fixing plate and is threadedly connected to the bottom shell, the process is simple, further reducing the difficulty of processing. When the decorative part needs to be repaired or removed, the threaded connector is easy to disassemble, thereby facilitating the disassembly and maintenance of the decorative part, and also facilitating the replacement of decorative parts of different colors and materials.

[0011] In another optional embodiment, the housing includes a bottom shell and a side portion. The side portion is arranged around the periphery of the bottom shell, and the first connection hole is opened in the side portion and penetrates the side portion. The bottom shell and the side portion surround a receiving cavity. The extension portion includes a side plate. The side plate is arranged around the periphery of the second connection hole and surrounds a third connection hole connected to the second connection hole. Along the axial direction of the first connection hole, the third connection hole penetrates the side plate. The side plate is connected to the side portion through a connecting piece.

[0012] At this time, after the decorative part of the decorative piece is extended into the first connecting hole opened on the side part, the side plate of the extension part and the shell can be relatively fixed by the connecting piece, thereby making the decorative piece relatively fixed to the bottom shell. In addition, the second connecting hole is connected to the third connecting hole, and the third connecting hole penetrates the side plate, thereby ensuring that the component in the accommodating cavity can pass through the third connecting hole and be arranged in the second connecting hole, and be connected to the external device that also extends into the second connecting hole.

[0013] In an optional embodiment, the connector is a threaded connector, which passes through the side plate and is threadedly connected to the side portion. When the threaded connector passes through the side plate and is threadedly connected to the side portion, the process is simple, further reducing the difficulty of processing. The threaded connector is easy to disassemble, thereby facilitating the disassembly and maintenance of the decorative part, and also facilitating the replacement of decorative parts of different colors and materials.

[0014] In an optional embodiment, the side plate abuts against the side portion. After the decorative part is extended into the first connection hole, the decorative part can be further positioned by abutting the side plate against the side portion of the shell, and then the decorative part is connected to the shell through the connecting member, so as to further improve the position accuracy between the decorative part and the shell.

[0015] In an optional embodiment, the surface of the side portion facing away from the bottom shell is higher than or flush with the surface of the side plate facing away from the bottom shell. In this case, the side of the side plate facing away from the bottom shell will not protrude from the side portion, thereby preventing the side plate from hindering the assembly of the housing assembly with other components.

[0016] In an optional embodiment, the housing assembly further includes a first seal. The first seal is disposed between the decorative portion and the inner wall of the first connection hole, and the decorative portion and the housing are sealed and connected via the first seal. In this case, the decorative portion and the housing can be sealed via the first seal, thereby improving the waterproof performance between the decorative portion and the housing.

[0017] In an optional embodiment, a groove is formed on one side of the decorative part facing the inner wall of the first connection hole. A portion of the first seal is located in the groove, and another portion of the first seal abuts against the inner wall of the first connection hole. The groove accommodates a portion of the first seal, thereby hindering the movement of the first seal along the axis of the first connection hole, ensuring that the first seal can always be located in the groove, preventing the first seal from being separated from between the decorative part and the inner wall of the first connection hole, and ensuring the waterproof performance between the decorative part and the housing.

[0018] In an optional embodiment, the decorative part includes a first annular structure and a second annular structure connected to each other. Relative to the first annular structure, the second annular structure is arranged close to the accommodating cavity. The first annular structure and the second annular structure surround a second connecting hole. The wall thickness of the first annular structure is smaller than the wall thickness of the second annular structure. At this time, the wall thickness of the first annular structure away from the accommodating cavity is smaller, that is, the end surface area of ​​the decorative part away from the accommodating cavity is smaller, and the area of ​​the decorative part seen from the outside of the first connecting hole is smaller, thereby ensuring the aesthetics of the decorative part. The groove is provided on the outer ring surface of the second annular structure. After the groove is provided on the outer surface of the second annular structure with a larger wall thickness, it can prevent the decorative part from being easily damaged due to the thickness of the decorative part between the bottom shell of the groove and the inner wall of the second connecting hole being too small after the groove is provided. In addition, the outer ring surface of the second annular structure protrudes from the outer ring surface of the first annular structure. Then, while ensuring that the wall thickness of the second annular structure is greater than the wall thickness of the first annular structure, it is prevented that the second annular structure protrudes inward too much, thereby preventing the external device from connecting with the components in the accommodating cavity.

[0019] In an optional embodiment, the shell includes a frame and a plastic part. A fourth connection hole that passes through the frame is provided on the frame. At least a portion of the decorative part extends into the fourth connection hole, and the extension portion is located on the side of the frame facing the accommodating cavity. A portion of the plastic part is arranged between the decorative part and the inner wall of the fourth connection hole, and another portion of the plastic part is arranged between the frame and the extension portion. The first connection hole is provided in the plastic part and passes through the plastic part. In practical applications, in the fourth connection hole, after the decorative part is in direct contact with the frame, the decorative part will affect the antenna radiation performance of the electronic device. In particular, when the decorative part is made of metal material, the impact is particularly obvious. However, plastic parts made of non-metallic materials will not affect the antenna radiation performance. At this time, a plastic part is provided between the decorative part and the inner wall of the fourth connection hole (i.e., the frame). A plastic part is also provided between the extension portion and the frame. In this way, the decorative part will not be in direct contact with the frame to reduce the impact on the antenna radiation performance.

[0020] In a second aspect of the present application, a decorative piece is provided, comprising a decorative portion and an extension portion. A second connection hole is provided on the decorative portion. The extension portion is arranged around the second connection hole and connected to the decorative portion. The decorative piece has the same technical effect as the decorative piece in the aforementioned housing assembly, and will not be described in detail here.

[0021] The third aspect of the present application provides an electronic device, comprising the above-mentioned connector. One end of the connector extends into the second connection hole, and the connector and the extension portion are connected to the shell through a connector. The end of the connector extending into the second connection hole can be connected to an external device extending into the second connection hole, so that the electronic device and the external device can transmit signals. Alternatively, the electronic device can be charged by connecting to an external power source through the connector. The connector, the extension portion and the shell are connected by a connector, so that the connector, the decorative member and the shell are relatively fixed. In addition, the above-mentioned electronic device has the same technical effect as the aforementioned shell assembly, which will not be repeated here.

[0022] In a fourth aspect of the present application, a shell assembly for an electronic device is provided, comprising a shell, a decorative member and a limit member. The shell is surrounded by a receiving cavity, and a first connecting hole penetrating the shell is provided on the shell. The decorative member comprises a decorative portion and an extension portion. The decorative portion is located in the first connecting hole and is arranged around the inner wall of the first connecting hole. A second connecting hole is provided on the decorative portion. The second connecting hole passes through the decorative portion along the axial direction of the first connecting hole. The extension portion is located in the receiving cavity and is arranged around the periphery of the second connecting hole. The extension portion is connected to the decorative portion. The limit member is located in the receiving cavity. The extension portion is arranged between the limit member and the shell, and the extension portion abuts against the limit member and the shell respectively, and the limit member is connected to the shell.

[0023] The decorative part of the decorative piece extends into the first connection hole, which can cover the inner wall of the first connection hole to improve the appearance of the first connection hole. The extension part is limited between the limiter and the shell by the limiter, so that the position of the decorative piece and the shell is relatively fixed. In this way, the decorative piece and the limiter can be assembled with the shell, and there is no need to injection mold the decorative piece and the shell together. The process is relatively simple, which can reduce the processing difficulty and processing cost of the decorative piece. In addition, by removing the limiter, the decorative piece and the shell can be separated, which is convenient for disassembly and maintenance of the decorative piece, and also convenient for replacing decorative pieces of different colors and materials.

[0024] The fifth aspect of the present application also provides an electronic device, including the above-mentioned shell assembly. Wherein, the limiting member includes a connector. One end of the connector extends into the second connecting hole, and the connector is connected to the shell. The end of the connector extending into the second connecting hole can be connected to an external device extending into the second connecting hole, so that the electronic device and the external device can transmit signals. Alternatively, the electronic device is charged by connecting to an external power source through the connector. After the connector is connected to the shell, the extension portion is limited so that the connector, the decorative member and the shell are relatively fixed. In addition, the above-mentioned electronic device has the same technical effect as the aforementioned shell assembly, which will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] In some embodiments, Figure 1 As shown, the electronic device 100 provided in the embodiment of the present application may include a housing assembly 10, a display module 20 and a back cover 30. For ease of understanding, the width direction of the electronic device is the X-axis, the thickness direction of the electronic device is the Y-axis, and the length direction of the electronic device is the Z-axis. Along the Z-axis direction, the display module 20 and the back cover 30 are respectively located on both sides of the housing assembly 10. The display module 20 has a display function. The housing assembly 10 can provide support for the display module 20.

[0046] Continue as Figure 1 As shown, the electronic device 100 may further include a circuit board 40 and a battery 50. The battery 50 can provide power for the display module 20. The circuit board 40 is used to realize the electrical connection and signal transmission functions between various components. The housing assembly 10 may include a housing 11. The housing 11 is surrounded by a housing cavity 111, and the housing cavity 111 can accommodate the circuit board 40 and the battery 50.

[0047] The above Figure 1 In the embodiment shown, the display module 20 is set on the housing assembly 10. In some embodiments of the present application, the display module 20 and the housing assembly 10 can also be two independent components, and the display module 20 is electrically connected to components such as a circuit board 40 set in the housing assembly 10 through a cable.

The housing 11 may be provided with a first connection hole 112 that penetrates the housing 11. For example, the axial direction of the first connection hole 112 may be the Z-axis direction. Figure 2 ( Figure 1 As shown in the partial schematic diagram of the electronic device at A shown in FIG. 1 , the connector 60 is connected to the housing 11, and one end of the connector 60 can extend into the first connection hole 112. Figure 1 As shown, one end of the connector 60 can be connected to an external device that also extends into the first connection hole 112, so that the electronic device 100 can transmit signals with the external device. Alternatively, the battery 50 of the electronic device 100 can be charged by connecting to an external power source through the connector 60.

[0049] Exemplarily, the connector 60 may be a Universal Serial Bus (USB) female socket, an earphone socket, or the like.

[0050] In order to ensure the exquisite appearance of the electronic device 100, a decorative piece may be provided in the first connection hole 112 (eg, a USB connection hole, an earphone connection hole, etc.) of the electronic device 100.

[0051] In some schemes, the decorative parts are first processed (such as: computer digital controlled precision machining), and then the decorative parts are inserted into the openings of the frame, and then the decorative parts and the frame are limited by the mold. Then, injection molding is performed between the decorative parts and the frame to form injection molded parts, and the decorative parts and the frame are fixed by the injection molded parts. In order to ensure the positioning accuracy of the decorative parts and the frame during injection molding, the precision of the injection molding equipment needs to be high, which makes the processing cost high. Even after the injection molding process is completed, the decorative parts need to be processed again so that the part of the decorative parts facing the outside of the opening is flush with the outer peripheral side of the frame. At this time, the decorative parts and the frame are relatively fixed, which makes the processing difficult and the processing cost high.

[0052] In order to reduce the processing difficulty and processing cost of the decorative element 12, some possible structures of the housing assembly 10 are first described as examples. Figure 3As shown, the housing assembly 10 may further include a decorative member 12 and a connecting member 13. Figure 4 As shown, the decorative element 12 may include a decorative portion 121 and an extension portion 122. The decorative portion 121 may be provided with a second connection hole 1211. Figure 5 ( Figure 2 As shown in the cross-sectional view of the electronic device in the direction P1-P2, the second connection hole 1211 penetrates the decorative portion along the axis direction Z of the first connection hole 112. One end of the connector 60 extending into the second connection hole 1211 can be connected to an external device extending into the second connection hole 1211.

[0053] Continue as Figure 5 As shown, the decorative portion 121 can be located in the first connection hole 112 and arranged around the inner wall of the first connection hole 112. For the convenience of explanation, along the direction parallel to the Z axis, the two ends of the arrow in the figure point to the inside of the shell 11 and the outside of the shell 11 respectively. The decorative portion 121 can conceal the inner wall of the first connection hole 112 to improve the appearance of the first connection hole 112 seen from the outside of the shell 11. The extension portion 122 can be located in the accommodating cavity 111 in the shell 11 and arranged around the second connection hole 1211, and the extension portion 122 is connected to the decorative portion 121. The connecting member 13 is located in the accommodating cavity 111. The extension portion 122 is connected to the shell 11 through the connecting member 13.

[0054] During assembly, the decorative portion 121 of the decorative member 12 is extended into the first connection hole 112. The extension portion 122 is connected to the housing 11 through the connection member 13, so that the positions of the decorative member 12 and the housing 11 are relatively fixed. In this way, the decorative member 12 can be assembled with the housing 11 alone, and there is no need to injection mold the decorative member 12 and the housing 11 together, the process is relatively simple, and the processing difficulty and processing cost of the decorative member 12 can be reduced.

[0055] By disassembling the connecting piece 13, the decorative piece 12 and the housing 11 can be separated, which is convenient for disassembly and maintenance of the decorative piece 12, and also convenient for replacing the decorative piece 12 with different colors and materials, thereby meeting the personalized needs of users.

[0056] Continue as Figure 5As shown, the housing 11 may include a bottom shell 113 and a side portion 114. The side portion 114 is arranged around the periphery of the bottom shell 113. The first connecting hole 112 may be opened in the side portion 114 and penetrate the side portion 114. The bottom shell 113 and the side portion 114 surround a receiving cavity 111. The extension portion 122 may include a side plate 1221. The side plate 1221 is arranged around the periphery of the second connecting hole 1211 and surrounds a third connecting hole 12211 that is connected to the second connecting hole 1211. Along the axial direction Z of the first connecting hole 112, the third connecting hole 12211 penetrates the side plate 1221. This ensures that one end of the connector 60 in the receiving cavity can pass through the third connecting hole 12211 and be arranged in the second connecting hole 1211, and be connected to an external device that also extends into the second connecting hole 1211, so that the external device is connected to the circuit board 40 (such as 40) arranged in the receiving cavity 111 through the connector 60. Figure 1 as shown) or battery 50 (as Figure 1 As shown) and other components are connected.

[0057] In an optional embodiment of the present application, as Figure 6 As shown, the extension part 122 may also include a fixing plate 1222. The fixing plate 1222 is located on the side of the side plate 1221 away from the decorative part 121, and the fixing plate 1222 is connected to the bottom shell 113 through the connecting member 13. At this time, after the decorative part 121 of the decorative member 12 is extended into the first connecting hole 112 opened on the side part 114, the fixing plate 1222 of the extension part 122 and the bottom shell 113 can be fixed by the connecting member 13, thereby fixing the decorative member 12 to the bottom shell 113. In the case where the size of the side part 114 away from the bottom shell 113 is small, when the fixing plate 1222 is connected to the bottom shell 113 for installation, the operating space on both sides of the installation position can be large, which facilitates the installation of the connecting member 13 to the extension part 122 and the housing 11. The processing difficulty and processing cost of the decorative member 12 are further reduced.

[0058] For example, continue as Figure 6 As shown, the connector 13 may be a threaded connector 13 (e.g., a bolt, a screw, etc.). The threaded connector 13 passes through the fixing plate 1222 and is threadedly connected to the bottom shell 113. The threaded connection is convenient for installation and removal. When the threaded connector 13 passes through the fixing plate 1222 and is threadedly connected to the bottom shell 113, the process is simple, further reducing the difficulty of processing. When the decorative part 12 needs to be repaired or removed, the threaded connector 13 is easy to disassemble, thereby facilitating the disassembly and maintenance of the decorative part 12, and also facilitating the replacement of decorative parts 12 of different colors and materials.

[0059] In order to allow the threaded connector 13 to penetrate the fixing plate 1222 and be threadedly connected to the bottom shell 113, continue as follows Figure 6As shown, the fixing plate 1222 may be provided with a first mounting hole 12221. The bottom shell 113 may be provided with a first threaded hole 1131. One end of the threaded connector 13 passes through the first mounting hole 12221 and is threadedly connected to the first threaded hole 1131.

[0060] Continue as Figure 6 As shown, the connector 60 may be provided with a second mounting hole 61. One end of the threaded connector 13 sequentially passes through the second mounting hole 61 and the first mounting hole 12221 and is threadedly connected to the first threaded hole 1131. At this time, the connector 60 and the fixing plate 1222 may be connected to the housing 11 through the threaded connector 13.

[0061] In order to further improve the position accuracy between the decorative element 12 and the housing 11, Figure 5 As shown, the side plate 1221 can abut against the side portion 114. After the decorative portion 121 is inserted into the first connection hole 112, the decorative member 12 can be further positioned by abutting the side plate 1221 against the side portion 114 of the housing 11, and then the decorative member 12 can be connected to the housing 11 through the connecting member 13. This further improves the position accuracy between the decorative member 12 and the housing 11.

[0062] In another optional embodiment of the present application, Figure 7 As shown, the side plate 1221 can be connected to the side portion 114 of the housing 11 through the connecting member 13. At this time, after the decorative portion 121 of the decorative member 12 is extended into the first connecting hole 112 opened on the side portion 114, the side plate 1221 of the extension portion 122 and the housing 11 can be relatively fixed through the connecting member 13, thereby making the decorative member 12 relatively fixed to the bottom shell 113.

[0063] like Figure 7 As shown, the connector 13 may also be a threaded connector 13, which passes through the side plate 1221 and is threadedly connected to the side portion 114. The installation process of the threaded connection is simple, which can further reduce the difficulty of processing. The threaded connector 13 is easy to disassemble, which facilitates the disassembly and maintenance of the decorative part 12, and also facilitates the replacement of the decorative part 12 of different colors and materials.

[0064] In order to allow the threaded connector 13 to penetrate the side plate 1221 and be threadedly connected to the side portion 114, as shown in FIG. Figure 7 As shown, the side plate 1221 may be provided with a third mounting hole 12212. Figure 7 As shown, a second threaded hole 1141 may be formed on the side portion 114. One end of the threaded connector 13 passes through the first mounting hole 12221 and is threadedly connected to the first threaded hole 1131.

[0065] Alternatively, and illustratively, in some embodiments of the present application, the connector 13 may also be a colloid (not shown in the figure). The colloid may be disposed between the extension portion 122 and the housing 11 by a dispensing process. For example, the colloid may be formed between the fixing plate 1222 and the bottom housing 113 by a dispensing process. Alternatively, the colloid may also be disposed between the side plate 1221 and the side portion 114 by a dispensing process.

[0066] Other possible structures of the housing assembly 10 are described below with examples.

[0067] like Figure 8 As shown, the housing assembly 10 may further include a decorative piece 12 and a limiting piece 14. The decorative piece 12 includes a decorative portion 121 and an extension portion 122. The decorative portion 121 is located in the first connecting hole 112 and is arranged around the inner wall of the first connecting hole 112. The decorative portion 121 of the decorative piece 12 extends into the first connecting hole 112, and can conceal the inner wall of the first connecting hole 112 to improve the appearance of the first connecting hole 112. A second connecting hole 1211 is provided on the decorative portion 121. Along the axial direction Z of the first connecting hole 112, the second connecting hole 1211 passes through the decorative portion 121. This allows the connector 60 (such as Figure 1 As shown in the figure, the external device can be inserted into the second connection hole 1211 and connected to the external device which is also inserted into the second connection hole 1211.

[0068] Continue as Figure 8 As shown, the extension portion 122 is located in the accommodating cavity 111 and is arranged around the second connecting hole 1211. The extension portion 122 is connected to the decorative portion 121. The limiting member 14 is located in the accommodating cavity 111. Along the Z-axis direction, the extension portion 122 is arranged between the limiting member 14 and the shell 11, and the extension portion 122 abuts against the limiting member 14 and the shell 11 respectively, and the limiting member 14 is connected to the shell 11. The extension portion 122 is limited between the limiting member 14 and the shell 11 by the limiting member 14, and then the extension portion 122 is limited along the Z-axis direction. After the decorative portion 121 extends into the first connecting hole 112, the shell 11 can hinder the movement of the decorative portion 121 in any direction on the plane where the X-axis and the Y-axis are located. Thereby, the position of the decorative member 12 and the shell 11 is relatively fixed. In this way, the decorative piece 12 and the stopper 14 can be assembled with the housing 11, and there is no need to injection mold the decorative piece 12 and the housing 11 together, which is relatively simple in process, thereby reducing the difficulty and cost of processing the decorative piece 12. In addition, by removing the stopper 14, the decorative piece 12 and the housing 11 can be separated, which is convenient for disassembly and maintenance of the decorative piece 12, and also convenient for replacing the decorative piece 12 of different colors and materials.

[0069] Exemplarily, the stopper 14 may be bonded to the housing 11. Alternatively, the stopper 14 is connected to the housing 11 by bolts, screws, pins, etc. This application does not make any specific limitation.

[0070] In some embodiments, Fig. 9 As shown, the connector 60 can be used as a stopper 14 to limit the extension portion 122. The extension portion 122 is respectively in contact with the connector 60 and the housing 11. After the connector 60 is fixedly connected to the housing 11, the extension portion 122 is limited between the connector 60 and the housing 11 by the connector 60, and the connector 60 can limit the extension portion 122 along the Z-axis direction.

[0071] In order to ensure that the housing assembly 10 and other components (such as Figure 1 The display module 20 shown in FIG. Fig.10 As shown, the side portion 114 faces away from the surface of the bottom shell 113 (eg Fig.10 S1 in the figure) is higher than or flush with the surface of the side plate 1221 away from the bottom shell 113 (as shown in Fig.10 The side of the side plate 1221 facing away from the bottom shell 113 will not protrude from the side portion 114, thereby preventing the side plate 1221 from hindering the assembly of the housing assembly 10 with other components.

[0072] In order to improve the waterproof performance between the decorative part 121 and the housing 11, Fig.11 As shown, the housing assembly 10 may further include a first seal 15. The first seal 15 is disposed between the decorative portion 121 and the inner wall of the first connection hole 112, and the decorative portion 121 and the housing 11 are sealed and connected through the first seal 15. The decorative portion 121 and the housing 11 can be sealed through the first seal 15 to achieve the purpose of improving the waterproof performance between the decorative portion 121 and the housing 11.

[0073] Continue as Fig.11 As shown, a groove 1212 may be provided on one side of the decorative part 121 facing the inner wall of the first connection hole 112. A portion of the first sealing member 15 may be located in the groove 1212, and another portion of the first sealing member 15 abuts against the inner wall of the first connection hole 112. The groove 1212 accommodates a portion of the first sealing member 15, thereby hindering the movement of the first sealing member 15 along the axial direction Z of the first connection hole 112, ensuring that the first sealing member 15 can always be located in the groove 1212, preventing the first sealing member 15 from being separated from between the decorative part 121 and the inner wall of the first connection hole 112, and ensuring the waterproof performance between the decorative part 121 and the housing 11.

[0074] Continue as Fig.11As shown, the decorative part 121 includes a first annular structure 1213 and a second annular structure 1214 connected to each other. Relative to the first annular structure 1213, the second annular structure 1214 is arranged close to the accommodating cavity 111. The first annular structure 1213 and the second annular structure 1214 surround a second connecting hole 1211. The wall thickness D1 of the first annular structure 1213 is less than the wall thickness D2 of the second annular structure 1214. The wall thickness of the first annular structure 1213 away from the accommodating cavity 111 is smaller, that is, the end surface area of ​​the decorative part 121 away from the accommodating cavity 111 is smaller, and the area of ​​the decorative part 12 seen from the outside of the first connecting hole 112 is smaller, thereby ensuring the aesthetics of the decorative part 121. The groove 1212 is provided on the outer ring surface of the second annular structure 1214. After the groove 1212 is opened on the outer surface of the second annular structure 1214 with a larger wall thickness, it can prevent the decorative part 121 between the bottom shell 113 of the groove 1212 and the inner wall of the second connecting hole 1211 from being too thin after the groove 1212 is opened, thereby preventing the decorative part 121 from being easily damaged.

[0075] Continue as Fig.11 As shown, the outer ring surface of the second annular structure 1214 protrudes from the outer ring surface of the first annular structure 1213. Thus, while ensuring that the wall thickness of the second annular structure 1214 is greater than that of the first annular structure 1213, the second annular structure 1214 is prevented from protruding too much inwards to hinder the connection between external equipment and components in the accommodating cavity 111.

[0076] For example, the above Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 or Fig.11 In any of the embodiments shown, the decorative portion 121 and the extension portion 122 may be integrally formed structural members, for example, integrally formed in one mold, or formed together through a process such as cutting.

[0077] As another example, the material of the decorative element 12 may be a metal material. The metal material has good hardness and glossiness, and the aesthetics of the decorative element 12 can be further improved while ensuring that the decorative element 12 has good structural rigidity.

[0078] Continue as Fig.11As shown, the housing 11 includes a frame 115 and a plastic part 116. The frame 115 is provided with a fourth connection hole 1151 that penetrates the frame 115. At least a portion of the decorative portion 121 extends into the fourth connection hole 1151, and the extension portion 122 is located on the side of the frame 115 facing the accommodating cavity 111. A portion of the plastic part 116 is disposed between the decorative portion 121 and the inner wall of the fourth connection hole 1151, and another portion of the plastic part 116 is disposed between the frame 115 and the extension portion 122. The first connection hole 112 is provided in the plastic part 116 and penetrates the plastic part 116.

[0079] In the fourth connection hole 1151, after the decorative part 12 is in direct contact with the frame 115, the decorative part 12 will affect the antenna radiation performance of the electronic device 100. In particular, when the decorative part 12 is made of metal material, the impact is particularly obvious. However, the plastic part 116 made of non-metallic material will not affect the antenna radiation performance. At this time, a plastic part 116 is arranged between the decorative part 121 and the inner wall of the fourth connection hole 1151 (i.e., the frame 115). A plastic part 116 is also arranged between the extension part 122 and the frame 115. In this way, the decorative part 12 will not be in direct contact with the frame 115, so as to reduce the impact on the antenna radiation performance.

[0080] For example, the plastic part 116 is formed on the frame 115 by injection molding, and the decorative part 12 is assembled only after the frame 115 and the plastic part 116 are formed. Compared with the plastic part 116 being formed after the decorative part 12 and the frame 115 are positioned, the positioning accuracy of the decorative part 12 and the housing 11 does not need to be considered during the injection molding process in the embodiment of the present application, which reduces the precision requirements of the injection molding equipment and can further reduce the processing cost.

[0081] like Fig.11 As shown, the electronic device 100 may further include a second seal 70. The second seal 70 is disposed between the connector 60 and the side portion 114 of the housing 11, and the connector 60 and the side portion 114 of the housing 11 are relatively sealed by the second seal 70. Thus, the waterproof performance of the electronic device 100 is ensured.

[0082] like Fig.12 As shown, a mounting groove 1132 is provided on the bottom shell 113. The mounting groove 1132 is used to accommodate the connector 60. A U-shaped groove 1133 is also provided on the groove wall of the mounting groove 1132. The connector 60 includes a connector body 62 and a protrusion 63. The U-shaped groove 1133 is used to accommodate the protrusion 63, and the U-shaped groove 1133 limits the protrusion 63 along the axial direction of the second connecting hole 1211.

[0083] It can be understood that the installation groove 1132, the U-shaped groove 1133, and the space enclosed by the bottom shell 113 and the side portion 114 all belong to the accommodating cavity 111 (such as Figure 1 shown).

[0084] In addition, continue Fig.12 As shown, the connector 60 further includes a tongue core 64, which is located in the second connection hole 1211 and is used for connecting to an external device.

[0085] The above embodiments all take the axial direction Z of the first connection hole 112 as the length direction of the electronic device as an example. In other embodiments of the present application, the axial direction of the first connection hole 112 may also be other directions, which is not specifically limited in the present application.

[0086] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
