Description

Technical Field

[0001] This application relates to the field of mobile terminal technology, and in particular to a housing assembly and an electronic device. Background Technology

[0002] Electronic devices typically have a camera module inside, and decorative camera parts are placed around the camera module. These decorative camera parts are fixed to the back cover of the electronic device and serve a decorative purpose for the camera module.

[0003] The camera trim is bonded to the back cover. When an external device is installed on the camera trim, the tension exerted by the external device on the camera bracket may cause the camera trim to fall off. Utility Model Content

[0004] This application provides a housing assembly and an electronic device, which aims to fix the middle frame and decorative parts to the side of the connector, ensuring the connection strength between the middle frame and the decorative parts while improving the aesthetic appearance of the electronic device.

[0005] This application provides a housing assembly, the housing assembly comprising:

[0006] A middle frame, wherein the middle frame is provided with an extension, and the extension is provided with a first connecting portion;

[0007] The decorative component has a second connecting portion on its sidewall in a direction perpendicular to the thickness direction of the housing assembly; the extension portion extends toward the decorative component along the thickness direction of the housing assembly and is disposed inside the decorative component; the first connecting portion and the second connecting portion are disposed opposite to each other in a direction perpendicular to the thickness direction of the housing assembly.

[0008] A connector, in a direction perpendicular to the thickness direction of the housing assembly, connects the first connecting portion and the second connecting portion.

[0009] In this embodiment, a portion of the middle frame extends toward the decorative element to form an extension. Along the thickness direction perpendicular to the housing assembly, the extension overlaps with the side wall of the decorative element. At this time, the first connecting portion of the extension and the second connecting portion of the side wall of the decorative element are correspondingly provided, so that the connector can connect the first connecting portion and the second connecting portion, thereby connecting the middle frame and the decorative element.

[0010] The connector secures the mid-frame and decorative elements from the side of the housing assembly, improving the stability of the connection between the decorative elements and the mid-frame, and preventing the connector from being directly visible from the back of the housing assembly, thus enhancing the aesthetics of the housing assembly and improving the user experience.

[0011] In one possible design, in a direction perpendicular to the thickness direction of the housing assembly, the first connecting portion is a hole structure penetrating the extension, and the second connecting portion is a hole structure penetrating the sidewall of the decorative element.

[0012] The connector includes a column body, a first sealing part and a second sealing part. Both the first sealing part and the second sealing part are sleeved on the column body. The first sealing part is interference-fitted with the first connecting part, and the second sealing part is interference-fitted with the second connecting part.

[0013] In this embodiment, the connector is fixed to the middle frame and the decorative part by means of shaft hole engagement, which simplifies the connection structure of the middle frame, the decorative part and the connector.

[0014] This application embodiment achieves a tight fit between the connector and the middle frame by setting the first sealing part of the connector to an interference fit with the first connecting part of the middle frame, thus preventing the connector from falling off the middle frame. Similarly, it achieves a tight fit between the connector and the middle frame by setting the second sealing part of the connector to an interference fit with the second connecting part of the decorative part, thus preventing the connector from falling off the decorative part. This ensures the stability of the connection between the middle frame and the decorative part and reduces the risk of the decorative part falling off under the pulling force of the external module.

[0015] In one possible design, the first connecting portion is an elliptical hole along the thickness direction of the housing assembly, the first sealing portion and the first connecting portion are interference fit, and in the direction perpendicular to the thickness direction of the housing assembly, the first sealing portion and the first connecting portion are clearance fit.

[0016] In this embodiment, the first sealing part can be made of rubber, which has the characteristics of high elasticity, high temperature resistance, aging resistance, and good mechanical properties, and can withstand large deformations. In this embodiment, the first sealing part can also buffer the contact between the decorative part and the column body when the decorative part is pulled by an external force, reducing the impact force exerted between the decorative part and the column body.

[0017] In this embodiment, the first connecting part is set as an elliptical hole, and the first sealing part and the first connecting part are interference-fitted in the thickness direction of the housing assembly, so that the first sealing part and the first connecting part are tightly fitted in the thickness direction of the housing assembly. This achieves contact between the elastic material of the first sealing part and the rigid material of the second connecting part, reducing the stress generated by the tight contact between the first sealing part and the first connecting part, thereby reducing the risk of deformation of the first sealing part and the first connecting part.

[0018] The first sealing part and the first connecting part are fitted with a clearance in the thickness direction perpendicular to the housing assembly, so that the first sealing part and the first connecting part have a clearance in the thickness direction perpendicular to the housing assembly to form a tolerance space, so as to facilitate the assembly and fitting of the first sealing part and the first connecting part.

[0019] In one possible design, the second connecting part is a circular hole, and the outer diameter of the second sealing part is 0.2mm-0.3mm larger than the diameter of the second connecting part.

[0020] In this embodiment, the second sealing part can be made of rubber, which has the characteristics of high elasticity, high temperature resistance, aging resistance, and good mechanical properties, and can withstand large deformations. In this embodiment, the second sealing part can also buffer the contact between the decorative part and the column body when the decorative part is pulled by external force, reducing the impact force exerted between the decorative part and the column body.

[0021] In this embodiment, when the connector and the decorative part are assembled, the second sealing part is squeezed to allow it to enter the second connecting part. When the connector and the decorative part are assembled in place, the second sealing part fits tightly against the inner wall of the second connecting part under its own elastic force, ensuring the sealing effect at the connection position of the second sealing part and the second connecting part. This effectively seals the connection position of the connector and the decorative part, preventing dust and liquid from the external environment from entering the interior of the housing assembly through the connection position of the connector and the decorative part. This prevents liquid from corroding the internal circuit of the housing assembly and causing damage to the internal circuit, thus giving the decorative part and the connector a waterproof effect.

[0022] In one possible design, the sidewall of the column body is provided with a first connecting groove, and the sidewall of the first connecting groove extends away from the second connecting part to the end of the column body, so that the sidewall of the first connecting groove away from the second connecting part has a notch structure.

[0023] The first sealing part is sleeved on the first connecting groove and the end of the column body near the first connecting groove.

[0024] In this embodiment of the application, the first connecting groove can position the first sealing part, and by setting the first connecting groove, the space occupied by the first sealing part can be reduced. That is, while ensuring a stable connection between the first sealing part and the first connecting part, it is beneficial to reduce the size of the first connecting part, thereby ensuring the structural strength of the extension.

[0025] In addition, the first sealing part is located at the insertion end of the connector. By setting the first sealing part to also be sleeved on the outer periphery of the insertion end of the connector, damage caused by hard contact between the connector and the decorative part and the middle frame is avoided.

[0026] In one possible design, the side wall of the column body is provided with a second connecting groove, and the second sealing part is sleeved in the second connecting groove.

[0027] In this embodiment of the application, the second connecting groove can play a positioning role for the second sealing part, and by setting the second connecting groove, the space occupied by the second sealing part can be reduced. That is, while ensuring a stable connection between the second sealing part and the second connecting part, it is beneficial to reduce the size of the second connecting part, thereby ensuring the structural strength of the side wall of the decorative part.

[0028] In one possible design, the inner wall of the first connecting part is provided with a limiting surface, and the outer side of the first sealing part is provided with a mating surface.

[0029] The limiting surface can mate with the mating surface to prevent the connector from disengaging from the outside of the housing assembly.

[0030] In this embodiment, when the connector moves to a preset position and is interference-fitted with the first and second connecting parts, the limiting surface and the mating surface mate accordingly to prevent the connector from disengaging from the outside of the housing assembly. Both the limiting surface and the mating surface are conical surfaces, ensuring high centering accuracy and guaranteeing the assembly accuracy and stability of the connector and the middle frame.

[0031] In one possible design, the sidewall of the decorative element away from the extension is also provided with a limiting groove, which is connected to the second connecting part;

[0032] The end of the connector away from the first sealing part is also provided with a limiting part. The diameter of the limiting part is larger than the diameter of the column body. The limiting part can abut against the bottom wall of the limiting groove to prevent the connector from disengaging into the interior of the housing assembly.

[0033] In this embodiment, after the connector is installed in place, the limiting part can abut against the bottom wall of the limiting groove to restrict the connector from entering the interior of the housing assembly under external force, thus ensuring the assembly yield of the connector with the middle frame and decorative parts.

[0034] In one possible design, the first sealing part is further provided with a first guide surface, which can guide the connector to cooperate with the second connecting part and the first connecting part.

[0035] In this embodiment, when the connector fixes the middle frame and the decorative part, the connector is pushed by an external force to insert the second connecting part and the first connecting part from the outer side of the decorative part. During this process, the first guide surface can guide the movement of the connector, guiding the connector to be inserted into the second connecting part and the first connecting part in sequence, thereby improving the assembly accuracy of the connector.

[0036] In one possible design, the inner wall of the first connecting part is provided with a second guide surface, and the second guide surface is located on the side of the limiting surface near the second connecting part. The second guide surface can guide the first sealing part to cooperate with the first connecting part.

[0037] In this embodiment, when the connector fixes the middle frame and the decorative part, the connector is pushed by an external force to insert the second connecting part and the first connecting part from the outer side of the decorative part. During this process, the second guide surface guides the connector to insert into the first connecting part, thereby improving the assembly accuracy of the connector.

[0038] In one possible design, the column body is made of a magnetic material, and the connector can be magnetically attracted away from the middle frame and the decorative piece.

[0039] In this embodiment, the disassembly tool can be a powerful magnet, and the connector can be attracted and detached from the middle frame and the decorative part by the powerful magnet, thereby disassembling the middle frame and the decorative part.

[0040] In one possible design, a first groove is provided at the exposed end of the column body in a direction perpendicular to the thickness direction of the housing assembly, and a second groove is provided on the side wall of the column body along the thickness direction of the housing assembly, with the first groove and the second groove communicating with each other.

[0041] The first groove and the second groove are used to engage with the hook of the disassembly tool so that the connector can be pulled away from the middle frame and the decorative piece.

[0042] In this embodiment, the first groove and the second groove are approximately perpendicular. The disassembly tool can be an L-shaped rod-like tool. When disassembling the connector, the end of the L-shaped rod-like tool is first inserted into the first groove, and then rotated 90° so that the end of the L-shaped rod-like tool enters the second groove. At this time, the end of the L-shaped rod-like tool abuts against the side wall of the second groove, causing the L-shaped rod-like tool to hook onto the connector. Pulling the L-shaped rod-like tool allows it to pull the connector away from the middle frame and the decorative piece, thereby disassembling the middle frame and the decorative piece.

[0043] This application also provides an electronic device, which includes a camera module, a display screen, and a housing assembly as described above, wherein the camera module and the display screen are mounted on the housing assembly.

[0044] In this embodiment, the housing assembly includes a mid-frame, a back cover, and decorative elements. The mid-frame supports the display screen, camera module, back cover, and decorative elements. Along the thickness direction of the electronic device, the display screen and back cover are respectively disposed on both sides of the mid-frame and are adhesively connected to the mid-frame. When the user uses the electronic device, the display screen faces the user, and the back cover faces away from the user. The camera module is mounted on the mid-frame and enables the electronic device to perform functions such as image acquisition and real-time video calls. The back cover has clearance holes, allowing part of the camera module structure to be exposed to the external environment through these holes. The decorative elements are adhesively attached to the side of the back cover facing away from the mid-frame, surrounding the camera module and serving to protect and decorate it, thereby enhancing the overall aesthetics of the electronic device.

[0045] In one possible design, the electronic device further includes an add-on module that is detachably mounted on the decorative element of the housing assembly.

[0046] In this embodiment, the external module is detachably installed on the side of the decorative piece away from the mid-frame. This external module can be an external cooling fan, an external camera, an external power bank, or other devices. The detachable connection between the external module and the decorative piece can be a snap-fit, magnetic, or other similar connection method. Attached Figure Description

[0069] With the improvement of electronic device performance and to provide users with more experiences, electronic devices can be connected to external devices, such as external cooling fans, external cameras, and external power banks. By connecting external devices to electronic devices, user needs can be met and the user experience can be improved.

[0070] Figure 1 This is a schematic diagram of the structure of electronic device 1. Figure 2 This is a schematic diagram of electronic device 1 from another perspective. Please refer to the reference. Figure 1 and Figure 2The electronic device 1 includes a display screen 11, a middle frame 12, and a back cover 13. Along the thickness direction Z of the electronic device 1, the display screen 11 and the back cover 13 are respectively disposed on both sides of the middle frame 12, and both the display screen 11 and the back cover 13 are bonded to the middle frame 12. The middle frame 12 is used to support the display screen 11 and the back cover 13. When the user uses the electronic device 1, the display screen 11 faces the user, and the back cover 13 faces away from the user.

[0071] Please continue to refer to the reference. Figure 1 and Figure 2 The electronic device 1 also includes a camera module (not shown) and a decorative element 14. The camera module enables the electronic device 1 to acquire images and perform real-time video calls. The camera module is mounted on the middle frame 12, and the rear cover 13 has a clearance hole (not shown), through which part of the camera module's structure can be exposed to the external environment. The decorative element 14 surrounds the camera module and is bonded to the middle frame 12, serving to protect and decorate the camera module, thereby enhancing the overall aesthetics of the electronic device 1.

[0072] Figure 3 This is a schematic diagram of electronic device 1 in another state. Electronic device 1 also includes an external module 15, which is detachably mounted on decorative component 14. The external module 15 can be an external cooling fan, an external camera, an external power bank, or other devices, depending on the actual situation. This embodiment does not limit the specific device.

[0073] The detachable connection method between the external module 15 and the decorative part 14 can be a snap-fit, magnetic attraction, or other methods, which can be set according to the actual situation. This embodiment does not limit it here.

[0074] Please refer to the reference. Figure 2 and Figure 3 The back cover 13 is glued to the middle frame 12, and the decorative part 14 is glued to the back cover 13. When the user installs the external module 15 onto the decorative part 14, the external module 15 exerts a pulling force on the decorative part 14 under its own weight, which affects the adhesive force between the decorative part 14 and the back cover 13, thus easily causing the decorative part 14 to fall off.

[0075] In some embodiments, to increase the connection strength between the decorative element 14 and the middle frame 12, the connection method between the middle frame 12, the back cover 13, and the decorative element 14 can be: the middle frame 12 and the back cover 13 are bonded together, and the middle frame 12 and the decorative element 14 are connected by screws on the front. In this embodiment, the screws are provided on the front of the decorative element 14, which means that the screws can be directly seen on the back of the electronic device 1, affecting the aesthetic appearance of the electronic device 1.

[0076] Alternatively, in other embodiments, to increase the connection strength between the decorative element 14 and the middle frame 12, the connection method of the middle frame 12, the back cover 13, and the decorative element 14 can be: the middle frame 12 and the back cover 13 are set as an integral structure, and the middle frame 12 is connected to the inner side of the decorative element 14 with screws. In this embodiment, the middle frame 12 and the back cover 13 are an integral structure, which increases the manufacturing cost. When maintaining the internal components of the electronic device 1 in the future (such as repairing or replacing the battery), it is necessary to disassemble the internal components over a large area, which increases the difficulty and cost of maintenance.

[0077] To address these technical problems, this application provides an electronic device 1. This electronic device 1 is not limited to mobile phones, tablets, laptops, etc. For ease of understanding, a mobile phone is used as an example for the electronic device 1 below. It should be noted that in the various figures of this application's embodiments, the directions of the X-axis, Y-axis, and Z-axis represent the width, length, and thickness directions of the electronic device 1, respectively.

[0078] Figure 4 This is an exploded view of electronic device 1. Electronic device 1 includes a display screen 11, a housing assembly (not shown), a camera module (not shown), and an external module 15. The housing assembly supports the display screen 11, the camera module, and the external module 15. The housing assembly includes a mid-frame 12, a back cover 13, and a decorative element 14. The mid-frame 12 supports the display screen 11, the camera module, the back cover 13, and the decorative element 14. The external module 15 is detachably mounted on the decorative element 14.

[0079] Specifically, along the thickness direction Z of the electronic device 1, the display screen 11 and the back cover 13 are respectively disposed on both sides of the middle frame 12 and are bonded to the middle frame 12. When the user uses the electronic device 1, the display screen 11 faces the user, and the back cover 13 faces away from the user. The camera module is installed on the middle frame 12 to enable the electronic device 1 to acquire images and perform real-time video calls. The back cover 13 is provided with clearance holes, through which part of the camera module structure can be exposed to the external environment. The decorative piece 14 is bonded to the side of the back cover 13 facing away from the middle frame 12. The decorative piece 14 surrounds the camera module, serving to protect and decorate the camera module, thereby enhancing the aesthetics of the entire electronic device 1. The external module 15 is detachably installed on the side of the decorative piece 14 facing away from the middle frame 12. This external module 15 can be an external cooling fan, an external camera, an external power bank, or other devices.

[0080] It should be noted that electronic device 1 also includes, but is not limited to, components such as batteries, motherboards, and circuit assemblies, which will not be described in detail in this embodiment.

[0081] Please continue to refer to this. Figure 4The electronic device 1 also includes connectors 16, which are fixedly connected to the middle frame 12 and the decorative element 14 on their sides. At least two connectors 16 are provided, and the at least two connectors 16 are evenly distributed along the circumference of the decorative element 14. Exemplarily, the number of connectors 16 can be three, four, five, six, etc., and the specific number of connectors 16 can be set according to actual conditions; this embodiment does not impose a limitation.

[0082] For example, this embodiment takes the setting of four connectors 16 as an example. In this embodiment, the shape of the decorative part 14 can be set as circular. The four connectors 16 are evenly distributed on the side of the decorative part 14 along the circumference of the decorative part 14, and fix the decorative part 14 and the middle frame 12.

[0083] Alternatively, in other embodiments, the shape of the decorative element 14 can be set to square, polygonal or other shapes, and the number of connectors 16 can be set according to the shape of the decorative element 14. The specific number can be set according to the actual situation, and this embodiment does not limit it.

[0084] The connection structure of the middle frame 12, decorative part 14 and connector 16 will be described in detail below with reference to the accompanying drawings.

[0085] Figure 5 This is a cross-sectional view of a portion of the structure of electronic device 1. Electronic device 1 includes a mid-frame 12, a decorative element 14, and a connector 16. The connector 16 fixes the mid-frame 12 and the decorative element 14 to the side of the device in a direction perpendicular to the thickness direction Y of electronic device 1. In this embodiment, the connector 16 fixes the mid-frame 12 and the decorative element 14, ensuring the connection strength between the mid-frame 12 and the decorative element 14 while concealing the connector 16 on the side of electronic device 1, thus improving the aesthetic appearance of electronic device 1 and enhancing the user experience.

[0086] Specifically, please refer to Figure 6 , Figure 6 for Figure 5 An enlarged schematic diagram of section A shows that the middle frame 12 has an extension 121 extending along the thickness direction Z of the electronic device 1 towards the decorative member 14 and located inside the decorative member 14. The extension 121 has a first connecting portion 121a. A second connecting portion 141 is provided on the side wall of the decorative member 14 in a direction perpendicular to the thickness direction Y of the electronic device 1. The first connecting portion 121a and the second connecting portion 141 are positioned opposite each other in the same direction. A connecting member 16 connects the first connecting portion 121a and the second connecting portion 141 to connect the extension 121 and the side wall of the decorative member 14, thereby fixing the middle frame 12 and the decorative member 14.

[0087] In other words, a portion of the structure of the middle frame 12 extends toward the decorative element 14 to form an extension 121. In the direction perpendicular to the thickness direction Y of the electronic device 1, the extension 121 overlaps with the side wall of the decorative element 14. At this time, the first connecting portion 121a of the extension 121 and the second connecting portion 141 of the side wall of the decorative element 14 are correspondingly provided, so that the connector 16 can connect the first connecting portion 121a and the second connecting portion 141, thereby connecting the middle frame 12 and the decorative element 14.

[0088] In this embodiment, by providing an extension 121 on the middle frame 12, a first connecting part 121a on the extension 121, and a second connecting part 141 on the side wall of the decorative part 14, the connector 16 can fix the middle frame 12 and the decorative part 14 from the side of the electronic device 1, thereby improving the connection stability between the decorative part 14 and the middle frame 12, and avoiding the connector 16 being directly visible from the back of the electronic device 1, thus enhancing the aesthetic appearance of the electronic device 1 and improving the user experience.

[0089] The colors of the connector 16 (surface exposed to the external environment) and the decorative part 14 (surface exposed to the external environment) can be the same. Both the surface coatings of the connector 16 and the decorative part 14 can be achieved using processes such as PVD (Physical Vapor Deposition) to further enhance the aesthetic appearance of the electronic device 1. Alternatively, the surface coatings of the connector 16 and the decorative part 14 can be achieved using other processes, which can be determined according to actual circumstances and are not limited in this embodiment.

[0090] Understandably, the number of extensions 121, the first connecting portion 121a, and the second connecting portion 141 is the same as the number of connectors 16.

[0091] It should be noted that, in this embodiment, the direction perpendicular to the thickness of the electronic device refers to either the width direction or the length direction of the electronic device, or any direction within the plane containing both the width and length directions of the electronic device, to facilitate illustrating the position of the connector installed on the electronic device. In this embodiment, the example shown uses the length direction of the electronic device as the direction perpendicular to the thickness of the electronic device.

[0092] Figure 7 This is a cross-sectional view of electronic device 1. In the direction perpendicular to the thickness direction Y of electronic device 1, the first connecting portion 121a is a hole structure penetrating the extension portion 121, and the second connecting portion 141 is a hole structure penetrating the side wall of the decorative member 14. The connecting member 16 includes a column body 161, a first sealing portion 162, and a second sealing portion 163, both of which are fitted onto the column body 161. Please refer to the reference. Figure 6 and Figure 7When the connector 16 connects the decorative part 14 and the middle frame 12, the first sealing part 162 is in an interference fit with the first connecting part 121a, and the second sealing part 163 is in an interference fit with the second connecting part 141.

[0093] In this embodiment, the connector 16 is fixed to the middle frame 12 and the decorative part 14 by means of shaft hole engagement, simplifying the connection structure of the middle frame 12, the decorative part 14 and the connector 16. This embodiment achieves a tight fit between the connector 16 and the middle frame 12 by setting the first sealing part 162 of the connector 16 to the first connecting part 121a of the middle frame 12, preventing the connector 16 from detaching from the middle frame 12. Similarly, by setting the second sealing part 163 of the connector 16 to the second connecting part 141 of the decorative part 14, a tight fit between the connector 16 and the middle frame 12 is achieved, preventing the connector 16 from detaching from the decorative part 14. This ensures the stability of the connection between the middle frame 12 and the decorative part 14 and reduces the risk of the decorative part 14 loosening under the pulling force of the external module 15.

[0094] Specifically, please refer to the following: Figure 6 and Figure 7 The second connecting part 141 is a circular hole, and the second sealing part 163 is a ring structure. The outer diameter of the second sealing part 163 is 0.2mm-0.3mm larger than the diameter of the second connecting part 141, so that the second sealing part 163 fits tightly with the inner wall of the second connecting part 141.

[0095] For example, the outer diameter of the second sealing part 163 can be 0.2mm, 0.21mm, 0.22mm, 0.23mm, 0.24mm, 0.25mm, 0.26mm, 0.27mm, 0.28mm, 0.29mm, 0.3mm, etc., larger than the diameter of the second connecting part 141. The specific size can be set according to the actual situation, and this embodiment does not limit it.

[0096] The second sealing part 163 can be made of rubber, which has the characteristics of high elasticity, high temperature resistance, aging resistance, and good mechanical properties, and can withstand large deformation. In this embodiment, the second sealing part 163 can also buffer the contact between the decorative part 14 and the column body 161 when the decorative part 14 is pulled by external force, thereby reducing the impact force exerted between the decorative part 14 and the column body 161.

[0097] In other words, when the connector 16 and the decorative part 14 are assembled, the second sealing part 163 is squeezed to allow it to enter the second connecting part 141. When the connector 16 and the decorative part 14 are in place, the second sealing part 163, under its own elastic force, fits tightly against the inner wall of the second connecting part 141, ensuring a sealing effect at the connection point between the second sealing part 163 and the second connecting part 141. This effectively seals the connection point between the connector 16 and the decorative part 14, preventing dust and liquid from the external environment from entering the interior of the electronic device 1 through the connection point, thus preventing liquid from corroding the internal circuitry of the electronic device 1 and causing damage. This also provides a waterproof effect between the decorative part 14 and the connector 16.

[0098] Please refer to Figure 8 , Figure 8 This is a partial structural diagram of the extension 121, where the first connecting part 121a on the extension 121 is an elliptical hole.

[0099] Please refer to the reference. Figure 6 , Figure 7 and Figure 8 The first connecting portion 121a can be an elliptical hole along the thickness direction Z of the electronic device 1, and the first sealing portion 162 and the first connecting portion 121a are interference fit. Specifically, along the thickness direction Z of the electronic device 1, the diameter of the first sealing portion 162 is 0.02mm-0.07mm larger than the diameter of the first connecting portion 121a.

[0100] For example, along the thickness direction Z of the electronic device 1, the diameter of the first sealing part 162 can be 0.02mm, 0.03mm, 0.04mm, 0.05mm, 0.06mm, 0.07mm, etc., larger than the diameter of the first connecting part 121a. The specific size can be set according to the actual situation, and this embodiment does not limit it.

[0101] Please continue to refer to the reference. Figure 6 , Figure 7 and Figure 8 The first connecting portion 121a can be an elliptical hole. In the direction perpendicular to the thickness direction Y of the electronic device 1, the first sealing portion 162 and the first connecting portion 121a are in clearance fit. Specifically, in the direction perpendicular to the thickness direction Y of the electronic device 1, the diameter of the first connecting portion 121a is 0.15mm-0.25mm larger than the diameter of the first sealing portion 162.

[0102] For example, along the thickness direction Y perpendicular to the electronic device, the diameter of the first connecting part 121a can be 0.15mm, 0.16mm, 0.17mm, 0.18mm, 0.19mm, 0.20mm, 0.21mm, 0.22mm, 0.23mm, 0.24mm, 0.25mm, etc., larger than the diameter of the first sealing part 162. The specific value can be set according to the actual situation, and this embodiment does not limit it.

[0103] The first sealing part 162 can be made of rubber, which has the characteristics of high elasticity, high temperature resistance, aging resistance, and good mechanical properties, and can withstand large deformation. In this embodiment, the first sealing part 162 can also buffer the contact between the decorative part 14 and the column body 161 when the decorative part 14 is pulled by external force, thereby reducing the impact force exerted between the decorative part 14 and the column body 161.

[0104] Specifically, in this embodiment, the first connecting part 121a is configured as an elliptical hole, and the first sealing part 162 and the first connecting part 121a are interference-fitted in the thickness direction Z of the electronic device 1, so that the first sealing part 162 and the first connecting part 121a are tightly fitted in the thickness direction Z of the electronic device 1. This achieves contact between the elastic material of the first sealing part 162 and the rigid material of the second connecting part 141, reducing the stress generated by the tight contact between the first sealing part 162 and the first connecting part 121a, thereby reducing the risk of deformation of the first sealing part 162 and the first connecting part 121a.

[0105] The first sealing part 162 and the first connecting part 121a are clearance-fitted in the direction perpendicular to the thickness direction X of the electronic device 1, so that the first sealing part 162 and the first connecting part 121a have a gap between them in the direction perpendicular to the thickness direction X of the electronic device 1 to form a tolerance space, so as to facilitate the assembly and cooperation of the first sealing part 162 and the first connecting part 121a.

[0106] It should be noted that the mating position of the second sealing part 163 and the second connecting part 141 mentioned above is located outside the mating position of the first sealing part 162 and the first connecting part 121a. The tight fit between the second sealing part 163 and the second connecting part 141 can effectively prevent liquid from the external environment from entering. In order to simplify the manufacturing process and assembly difficulty, the second sealing part 163 and the second connecting part 141 can be clearance-fitted in the direction perpendicular to the thickness direction X of the electronic device 1.

[0107] Alternatively, in other embodiments, the first connecting portion 121a may also be configured as a circular hole, and the first sealing portion 162 and the first connecting portion 121a may be an interference fit. The specific configuration can be determined according to actual circumstances, and this embodiment does not impose any limitations.

[0108] Please refer to Figure 9 , Figure 9 The diagram shows the structure of the column body 161. The sidewall of the column body 161 is provided with a first connecting groove 161a and a second connecting groove 161b, which are distributed along the axial direction of the column body 161. The sidewall of the first connecting groove 161a extends away from the second connecting portion 141 to the end penetrating the column body 161, so that the sidewall of the first connecting groove 161a away from the second connecting portion 141 has a notch structure. Both the first connecting groove 161a and the second connecting groove 161b are arranged around the entire circumference of the column body 161.

[0109] Figure 10 This is a structural schematic diagram of connector 16. Please refer to the reference diagram. Figure 9 and Figure 10 The first sealing part 162 is sleeved on the first connecting groove 161a and the end of the column body 161 near the first connecting groove 161a, and the second sealing part 163 is sleeved on the second connecting groove 161b.

[0110] In this embodiment, the first connecting groove 161a can position the first sealing part 162, and by setting the first connecting groove 161a, the space occupied by the first sealing part 162 can be reduced. That is, while ensuring that the first sealing part 162 and the first connecting part 121a are stably connected, it is beneficial to reduce the size of the first connecting part 121a, thereby ensuring the structural strength of the extension part 121.

[0111] The second connecting groove 161b can position the second sealing part 163. By setting the second connecting groove 161b, the space occupied by the second sealing part 163 can be reduced. That is, while ensuring a stable connection between the second sealing part 163 and the second connecting part 141, it is beneficial to reduce the size of the second connecting part 141, thereby ensuring the structural strength of the side wall of the decorative part 14.

[0112] In addition, the first sealing part 162 is located at the insertion end of the connector 16. By setting the first sealing part 162 to also be sleeved on the outer periphery of the insertion end of the connector 16, damage caused by hard contact between the connector 16 and the decorative part 14 and the middle frame 12 is avoided.

[0113] In some embodiments, the first sealing part 162 is injection molded into the first connecting groove 161a, and the second sealing part 163 is injection molded into the second connecting groove 161b, thereby improving the connection stability between the first sealing part 162 and the column body 161 and the second sealing part 163 and the column body 161. Moreover, injection molding is an automated production process with high production efficiency, precise dimensions, and low production costs.

[0114] Alternatively, the first sealing part 162 can be fixed to the first connecting groove 161a in other ways, and the second connecting part 141 can be fixed to the second connecting groove 161b in other ways, such as bonding, interference fit, etc. The specific method can be set according to the actual situation, and this embodiment does not limit it.

[0115] Figure 11 The diagram shows a cross-sectional view of the first connecting portion 121a. The inner wall of the first connecting portion 121a is provided with a limiting surface 121a1 and a second guide surface 121a2. The second guide surface 121a2 is located on the side of the limiting surface 121a1 near the second connecting portion 141. The limiting surface 121a1 restricts the connector 16 from detaching from the outside of the electronic device 1, and the second guide surface 121a2 guides the connector 16 to engage with the first connecting portion 121a. In other words, towards the direction near the second connecting portion 141, the limiting surface 121a1 is a sloped area in the first connecting portion 121a with a gradually decreasing diameter, and the second guide surface 121a2 is a sloped area in the first connecting portion 121a with a gradually increasing diameter.

[0116] Figure 12 The diagram shows a cross-sectional view of the connector 16. The outer surface of the first sealing portion 162 is provided with a mating surface 162a and a first guide surface 162b. The first guide surface 162b is located on the side of the mating surface 162a near the first connecting portion 121a. The mating surface 162a is used to prevent the connector 16 from detaching from the outside of the electronic device 1, and the first guide surface 162b is used to guide the connector 16 to mate with the second connecting portion 141 and the first connecting portion 121a. In other words, towards the first connecting portion 121a, the mating surface 162a is a sloped area in the first sealing portion 162 with a gradually increasing diameter, and the first guide surface 162b is a sloped area in the first sealing portion 162 with a gradually decreasing diameter.

[0117] Please refer to the reference. Figure 6 , Figure 7 , Figure 11 and Figure 12 When the connector 16 fixes the middle frame 12 and the decorative part 14, the connector 16 is pushed by an external force to insert the second connecting part 141 and the first connecting part 121a from the outer side of the decorative part 14. During this process, the first guide surface 162b and the second guide surface 121a2 can guide the movement of the connector 16, guiding the connector 16 to be inserted into the second connecting part 141 and the first connecting part 121a in sequence. At the same time, the second guide surface 121a2 guides the connector 16 to be inserted into the first connecting part 121a, thereby improving the assembly accuracy of the connector 16.

[0118] After the connector 16 moves to the preset position, it is interference-fitted with the first connecting part 121a and the second connecting part 141. At this time, the limiting surface 121a1 and the mating surface 162a are correspondingly engaged to prevent the connector 16 from disengaging from the outside of the electronic device 1. In this embodiment, both the limiting surface 121a1 and the mating surface 162a are set as conical surfaces, which have high centering accuracy and ensure the assembly accuracy and stability of the connector 16 and the middle frame 12.

[0119] Figure 13 This is a cross-sectional schematic diagram of decorative component 14. Figure 14 for Figure 13 Please refer to the enlarged diagram of section B. Figure 13 and Figure 14 The decorative part 14 is provided with a limiting groove 142 on the side wall away from the extension 121, and the limiting groove 142 is connected to the second connecting part 141.

[0120] Please continue to refer to this. Figure 12 The end of the connector 16 away from the first sealing part 162 is also provided with a limiting part 164. The limiting part 164 is connected to the column body 161, and the diameter of the limiting part 164 is larger than the diameter of the column body 161.

[0121] Please refer to the reference. Figure 12 and Figure 14 After the connector 16 is installed in place, the limiting part 164 can abut against the bottom wall of the limiting groove 142 to restrict the connector 16 from entering the interior of the electronic device 1 under the push of external force, so as to ensure the assembly yield of the connector 16 with the middle frame 12 and the decorative part 14.

[0122] Please continue to refer to this. Figure 14 The limiting part 164 is the part of the connector 16 exposed to the external environment of the electronic device 1. By cooperating with the limiting groove 142, the limiting part 164 can be hidden in the limiting groove 142, so as to prevent the connector 16 from protruding from the side wall of the decorative part 14.

[0123] Please continue to refer to this. Figure 14 The decorative part 14 is also provided with a snap-fit ​​part 143 for cooperating with the external module 15. The snap-fit ​​part 143 can be provided on the outside of the limiting groove 142 so as to further cover the connector 16.

[0124] When it is necessary to disassemble and maintain the internal components of the electronic device 1, or remove the middle frame 12 and decorative parts 14, the connector 16 can be removed with the help of a disassembly tool.

[0125] Specifically, in one embodiment, the column body 161 can be made of a magnetic material, such as a stainless steel column, and the disassembly tool can be a strong magnet. The connector 16 can be attracted and detached from the middle frame 12 and the decorative part 14 by the strong magnet, thereby disassembling the middle frame 12 and the decorative part 14.

[0126] In another embodiment, please continue to refer to Figure 10 In the direction perpendicular to the thickness direction Y of the electronic device 1, a first groove 161c is provided at the end of the column body 161 exposed to the external environment. Along the thickness direction Z of the electronic device 1, a second groove 161d is provided on the side wall of the column body 161. The first groove 161c and the second groove 161d are connected. The first groove 161c and the second groove 161d are arranged approximately perpendicularly.

[0127] A similar L-shaped tool can be used for disassembly. When disassembling connector 16, first insert the end of the L-shaped tool into the first groove 161c. Then, rotate the L-shaped tool 90° so that its end enters the second groove 161d. At this point, the end of the L-shaped tool abuts against the side wall of the second groove 161d, causing it to hook onto connector 16. Finally, pull the L-shaped tool; it will pull connector 16 away from the middle frame 12 and decorative piece 14, thus disassembling the middle frame 12 and decorative piece 14.

[0128] Alternatively, in other embodiments, the connector can be disassembled in other ways, depending on the actual situation. This embodiment is not described here.

[0129] In some embodiments, the extension 121 may also be provided with a positioning structure, and the inner sidewall of the decorative member 14 is provided with a positioning structure. The positioning structure can cooperate with the positioning structure to position the first connecting part 121a and the second connecting part 141, thereby improving assembly efficiency.

[0130] In practical applications, in addition to the connection structure between the middle frame 12 and the decorative part 14 described above, the scheme of fixing the middle frame 12 and the decorative part 14 to the side of the connector 16 in this application embodiment can also be applied to other positions of the electronic device 1 to fix other components. This application embodiment does not limit this.

Any changes or substitutions within the technical scope disclosed in the embodiments of this application should be covered within the protection scope of the embodiments of this application. Therefore, the protection scope of the embodiments of this application should be determined by the protection scope of the claims.
