Description

Technical Field

[0001] This application relates to the field of electronic product accessories, and more particularly to a protective case and an electronic device. Background Technology

[0002] Protective cases with a rotatable ring-shaped metal stand are widely used in electronic products such as mobile phones and tablets. The ring-shaped metal stand can support electronic products at multiple angles and can also be adapted to ring-shaped wireless charging docks (for wirelessly charging electronic products) via the ring-shaped magnet array built into the metal stand.

[0003] When electronic products are charged with protective cases, the ring-shaped metal bracket often cannot completely avoid the effective wireless charging area. A large closed conductive loop is formed within the conventional ring-shaped metal bracket, which, when coupled with the alternating magnetic field of the wireless charger, causes power to dissipate as heat, significantly reducing charging efficiency. Furthermore, the temperature rise of both the ring-shaped metal bracket and the electronic product during wireless charging may trigger the foreign object detection (FOD) mechanism of the wireless charging pad, limiting the charging power to a low level or even stopping charging altogether, failing to meet higher power charging demands. Additionally, the increased temperature can pose safety hazards and negatively impact the user experience. Summary of the Invention

[0004] This application provides a protective case and an electronic device that can ensure the charging efficiency of electronic products when wirelessly charging with the protective case on, and improve the heat generation phenomenon during wireless charging.

[0005] In a first aspect, embodiments of this application provide a protective shell, including a shell, an annular bracket, a hinge, and an insulating portion; the annular bracket forms a non-closed ring with an opening, and the annular bracket is a conductor; the hinge is rotatably connected to the shell, and the portions of the hinge and the annular bracket located on both sides of the opening are fixedly connected; the hinge is a conductor; at least a portion of the insulating portion is located between the hinge and the annular bracket, and the insulating portion is used to electrically isolate the hinge from the annular bracket.

[0006] In this embodiment, the annular bracket is broken to form an opening, and the hinge spans the opening, with the annular bracket fixedly connected to both sides of the opening. By providing an opening on the annular bracket, the annular bracket itself cannot form a closed conductive loop. The insulating part is an insulator. By providing the insulating part, the hinge is electrically isolated from the annular bracket, preventing the formation of a closed conductive loop in the bracket assembly of the protective shell. Even if the bracket assembly overlaps with the effective area of ​​wireless charging, the bracket assembly will not couple with the alternating magnetic field of wireless charging to consume charging power, which helps ensure charging efficiency. Furthermore, the temperature rise of the bracket assembly during wireless charging is small, which helps reduce the probability of FOD response of the wireless charging base and helps ensure that electronic devices are charged with a higher charging power. Reducing the heat generation of the bracket assembly also ensures that electronic devices can be wirelessly charged more safely.

[0007] In this embodiment of the application, after the ring-shaped bracket is broken to form an opening, the hinge can be made to span the opening and be fixedly connected to the ring-shaped bracket, which can ensure the rigidity and structural strength of the bracket assembly, thereby ensuring the mechanical reliability of the bracket assembly.

[0008] This application embodiment avoids the formation of a closed conductive circuit by eliminating the need to fill the opening with plastic. Since only the opening is provided without filling it with plastic, there is no need to consider the process requirements required for filling with plastic, which allows the opening to be made smaller. This is beneficial for improving the appearance quality of the bracket assembly, especially enhancing the appearance of the outer surface of the protective shell.

[0009] In one implementation of the first aspect, the insulating part is integrated with the hinge or mounted on the hinge.

[0010] In this implementation, the isolating part and the hinge are integrated, meaning the isolating part can be manufactured together with the hinge during its manufacturing process. The isolating part is tightly attached to the surface of the hinge, and the two can only be separated by destructive means. Alternatively, the isolating part can be installed on the hinge, meaning the isolating part and the hinge are manufactured in different processes; they are independent components connected by an assembly process.

[0011] In this implementation, the isolating part and the hinge are integrated, allowing the isolating part to be manufactured during the hinge manufacturing process. This saves assembly steps and ensures product precision and reliability. Manufacturing and assembling the isolating part and hinge separately can meet certain product requirements. For example, it allows the OEM to connect the isolating part, hinge, and ring bracket simply by assembling the isolating part, eliminating the need for secondary processing and improving the OEM's production efficiency.

[0012] In one implementation of the first aspect, the hinge includes a first surface whose normal is along the axial direction of the annular support; the entire area of ​​the first surface is covered by an insulating portion, and the first surface is connected to the annular support through the insulating portion.

[0013] In this implementation, by covering the first surface of the annular bracket with an insulating portion, the insulating portion can be provided at least on the first surface where the hinge connects to the annular bracket, thus ensuring the insulating effect.

[0014] In one implementation of the first aspect, the hinge further includes a second surface and a side surface, the second surface being spaced apart from the first surface and the side surface connecting the second surface and the first surface; the hinge has a plurality of through holes penetrating the first surface and the second surface, the plurality of through holes being located on both sides of the opening; an insulating portion covers at least a portion of the second surface and the inner wall of each through hole; the protective shell further includes a plurality of connecting portions, each connecting portion passing through a through hole and fixedly connecting the hinge and the annular bracket; the connecting portions are conductors.

[0015] In this implementation, by providing a connecting portion, the hinge and the annular bracket are fixedly connected, ensuring the connection strength between the hinge and the annular bracket, as well as the mechanical reliability of the bracket assembly. By covering at least a portion of the second surface and the inner wall of each through hole with an insulating portion, electrical isolation is formed between the hinge and the connecting portion, thereby ensuring that no closed conductive loop is formed in the bracket assembly.

[0016] In one implementation of the first aspect, the insulating part is integrated with the hinge, and the insulating part covers the entire area of ​​the second surface.

[0017] In this implementation, when the insulating part is integrated with the hinge, the insulating part can cover the entire area of ​​the second surface, thereby ensuring sufficient electrical isolation between the hinge and the connecting part, and ensuring that no closed conductive loop is formed in the bracket assembly.

[0018] In one implementation of the first aspect, the isolation portion is mounted on the hinge member; the isolation portion includes a first sub-isolation portion and a second sub-isolation portion; the first sub-isolation portion covers the entire area of ​​the first surface; the second sub-isolation portion is connected to the first sub-isolation portion and covers the entire area of ​​the second surface and the inner wall of each through hole.

[0019] In this implementation, when the isolating part and the hinge are assembled and connected, the isolating part may include two independent components—a first sub-isolating part and a second sub-isolating part. Before assembly, both the first and second sub-isolating parts can be sheet-like structures. Several through holes can be formed on both the first and second sub-isolating parts, and the connecting part passes through these through holes to fix the annular bracket, the isolating part, and the hinge. The first sub-isolating part can electrically isolate the first surface of the hinge from the annular bracket, and the second sub-isolating part can isolate the second surface of the hinge and the inner wall of each through hole from the connecting part. This ensures sufficient electrical isolation between the hinge and the annular bracket, preventing the formation of a closed conductive loop in the bracket assembly.

[0020] In this implementation, for example, the connecting part can be a riveting post, which connects the annular bracket, the isolating part, and the hinge through a riveting process. The through hole on the second sub-isolating part can be smaller, while the through hole on the first sub-isolating part can be larger. When the connecting part deforms during riveting, it can compress the second sub-isolating part, causing it to bend, ultimately connecting the second sub-isolating part with the first sub-isolating part and covering the inner wall of the through hole of the hinge. Alternatively, the diameter of the through hole on the second sub-isolating part can be substantially the same as that of the through hole on the first sub-isolating part, and a portion of the second sub-isolating part can be bent toward the first sub-isolating part to form the through hole of the second sub-isolating part, or in other words, the bent portion of the second sub-isolating part can form a hollow sleeve structure. During assembly, the bent portion of the second sub-isolating part can connect with the first sub-isolating part, and this bent portion can cover the inner wall of the through hole of the hinge.

[0021] In one implementation of the first aspect, the isolation portion is mounted on the hinge member; the isolation portion includes a first sub-isolation portion and a plurality of second sub-isolation portions; the first sub-isolation portion and the plurality of second sub-isolation portions together cover a first surface, and each second sub-isolation portion also covers a partial area of ​​a second surface and the inner wall of a through hole.

[0022] In this implementation, when the isolating part and the hinge are assembled and connected, the isolating part may include two independent components—a first sub-isolating part and multiple second sub-isolating parts. Before assembly, the first sub-isolating part may be a sheet-like structure, and the second sub-isolating parts may be generally cylindrical or nut-shaped. Several through holes may be formed on the first sub-isolating part. The connecting part passes through the through holes on the first sub-isolating part and the second sub-isolating part, and fixes the annular bracket, the isolating part, and the hinge to each other. The first surface can be covered by the first sub-isolating part and the multiple second sub-isolating parts to electrically isolate the first surface from the annular bracket; the second sub-isolating parts can isolate a local area of ​​the second surface of the hinge and the inner wall of the through holes from the connecting part, thereby ensuring sufficient electrical isolation between the hinge and the annular bracket, and ensuring that no closed conductive loop is formed in the bracket assembly.

[0023] This implementation can meet certain product requirements. For example, it allows the OEM to connect the isolation part with the hinge and the ring bracket simply by assembling the isolation part, without the need for secondary processing (such as riveting), which helps improve the production efficiency of the OEM.

[0024] In one implementation of the first aspect, the hinge further includes a side surface connected to the first surface and forming an angle, and a gap exists between the side surface and the annular support.

[0025] In this implementation, the portion connecting the hinge to the annular support can be sheet-like, and its thickness direction can be defined. The side of the hinge is parallel to this thickness direction, and the thickness of the sheet-like portion is the height of that side. The insulating portion may not cover the side of the hinge; the side can be exposed. This design improves the manufacturability of the insulating portion.

[0026] In one implementation of the first aspect, the area where the annular support connects to the hinge is provided with an insulating material layer.

[0027] In this implementation, an insulating material layer can also be provided in the area of ​​the ring-shaped bracket where it connects to the hinge. This insulating material layer has insulating properties and is used to enhance the electrical isolation between the ring-shaped bracket and the hinge. Furthermore, this insulating material layer can still ensure electrical isolation between the ring-shaped bracket and the hinge even after the insulating portion is damaged. The actual coverage area of ​​this insulating material layer can be set as needed, and it can be as large as possible to ensure the electrical isolation effect.

[0028] In one implementation of the first aspect, the insulating material layer can be an oxide layer, such as an oxide layer formed by a deep anodizing process. This type of insulating material layer is relatively stable and has reliable insulation properties.

[0029] In one implementation of the first aspect, the width of the opening of the annular support is 0.5 mm to 5 mm.

[0030] In this implementation, by setting the width of the opening within this range, the manufacturing and assembly errors of each component can be covered, ensuring that the ring bracket remains open rather than closed when the bracket assembly is installed into the housing and when deformation occurs during the operation of the bracket assembly, so as to ensure that the ring bracket will not form a closed conductive circuit when the electronic device is wirelessly charged with a protective case.

[0031] Secondly, embodiments of this application provide a protective shell, including a shell, a rotating shaft, an annular bracket, and two hinged portions; the rotating shaft is disposed on the shell; the rotating shaft includes a first segment, a second segment, and a third segment connected sequentially along the axial direction, the first segment and the third segment being conductors, and the second segment being an insulator; or, the rotating shaft includes a first sub-shaft and a second sub-shaft, the first sub-shaft and the second sub-shaft having a gap, the first sub-shaft and the second sub-shaft being conductors; the annular bracket forms a non-closed ring with an opening, the annular bracket being a conductor; both hinged portions are conductors; both hinged portions are fixedly connected to the annular bracket and are respectively located on both sides of the opening; both hinged portions are connected to the rotating shaft and rotatably connected to the shell through the rotating shaft, wherein, when the rotating shaft includes a first segment, a second segment, and a third segment, the two hinged portions are respectively connected to the first segment and the third segment; when the rotating shaft includes a first sub-shaft and a second sub-shaft, the two hinged portions are respectively connected to the first sub-shaft and the second sub-shaft.

[0032] In this embodiment, the rotating shaft can be fixed to the housing, and the two hinged parts are rotatably connected to the rotating shaft; or, the rotating shaft can be rotatably connected to the housing, and the two hinged parts are fixedly connected to the rotating shaft, thereby realizing the design of the two hinged parts rotating relative to the housing through the rotating shaft.

[0033] In this embodiment, since the annular support has an opening, the annular support itself cannot form a closed conductive loop.

[0034] In this embodiment, when the hinge comprises a first, second, and third segment, the second segment is an insulator, preventing the two hinged parts from conducting through the hinge. Therefore, the annular bracket cannot form a closed conductive loop through the hinge. Similarly, when the hinge comprises a first sub-shaft and a second sub-shaft, the gap between the first and second sub-shafts prevents the annular bracket from forming a closed conductive loop through them. Therefore, even if the bracket assembly overlaps with the effective area of ​​wireless charging, the bracket assembly will not couple with the alternating magnetic field of wireless charging to consume charging power, thus ensuring charging efficiency. Furthermore, the temperature rise of the bracket assembly during wireless charging is relatively small, which helps reduce the probability of FOD response of the wireless charging base and ensures that electronic devices are charged with a higher charging power. The reduced heat generation of the bracket assembly also ensures safer wireless charging for electronic devices.

[0035] Thirdly, embodiments of this application provide a protective shell, including a shell, a rotating shaft, an annular support, and two hinged portions; the annular support forms a non-closed ring with an opening, and the annular support is a conductor; the rotating shaft is disposed on the shell, and the rotating shaft is a conductor; both hinged portions are conductors; both hinged portions are fixedly connected to the annular support and are respectively located on both sides of the opening; both hinged portions are connected to the rotating shaft and rotatably connected to the shell through the rotating shaft; the outer surface of the rotating shaft is provided with an insulating material layer, and / or, the areas where the two hinged portions are connected to the rotating shaft are provided with an insulating material layer.

[0036] In this embodiment, the insulating material layer may cover only the entire or a portion of the circumferential surface of the shaft; alternatively, the insulating material layer may cover both the circumferential and axial surfaces of the shaft. The insulating material layer possesses insulating properties. The insulating material layer is formed, but is not limited to, by methods such as oxidation, PVD, and chemical plating.

[0037] In this embodiment, because the annular bracket has an opening, it cannot form a closed conductive loop. Since the outer surface of the pivot and / or the two hinges are provided with insulating material layers, the two hinges cannot conduct through the pivot, and therefore the annular bracket cannot form a closed conductive loop through the pivot. Therefore, even if the bracket assembly overlaps with the effective area of ​​wireless charging, the bracket assembly will not couple with the alternating magnetic field of wireless charging to consume charging power, which helps ensure charging efficiency. Furthermore, the temperature rise of the bracket assembly during wireless charging is small, which helps reduce the probability of FOD response of the wireless charging base and helps ensure that electronic devices are charged with a higher charging power. The reduced heat generation of the bracket assembly also ensures that electronic devices can be wirelessly charged more safely.

[0038] In any of the above implementations, the protective housing may further include a cover that covers the annular support, the insulating portion, and the hinge portion; or the cover covers the insulating portion and the hinge portion; or the cover covers the area of ​​the annular support where an opening is provided. When the annular support is closed relative to the housing, the cover is located on the side of the annular support or the hinge portion facing the housing; the cover is an insulator. When the support assembly is flipped open relative to the housing, the cover can face outwards, and internal structures, such as the connecting portion and the insulating portion, are covered by the cover, thus giving the inner surface of the support assembly a more integrated appearance. Furthermore, since the cover is an insulator, it will not cause a closed conductive loop to be formed in the annular support.

[0039] Fourthly, embodiments of this application provide an electronic device, including an electronic device and a protective case, wherein the electronic device is mounted on the side of the protective case facing away from the annular support; the electronic device has a built-in wireless charging module.

[0040] In this embodiment, the electronic device can also be referred to as an electronic component. The electronic device and the protective case are independent of each other, and the electronic device can function normally after being removed from the protective case. When the electronic device is wirelessly charged with the protective case on, the support assembly of the protective case is unlikely to couple with the alternating magnetic field of the wireless charging, thus minimizing charging power consumption and ensuring charging efficiency. Furthermore, the temperature rise of the support assembly is relatively small during wireless charging, which helps reduce the probability of FOD response of the wireless charging base and ensures that the electronic device can be charged with a higher charging power. The reduced heat generation of the support assembly also ensures that the electronic device can be wirelessly charged more safely. Attached Figure Description

[0071] This application provides an electronic device, including an electronic device and a protective case. The electronic device can be detachably installed in the protective case, which protects the electronic device. A support assembly on the protective case can also be unfolded to support the electronic device, facilitating placement and use by the user. The electronic device includes, but is not limited to, mobile phones (candybar phones or foldable phones), tablet computers, personal digital assistants (PDAs), etc. The electronic device may have wireless charging capabilities.

[0072] Figure 1 This diagram illustrates an exploded view of the electronic device 1 in one embodiment. Figure 2 for Figure 1 A schematic diagram of the assembly structure of electronic device 1 in the diagram. (See attached diagram.) Figure 1 and Figure 2 As shown, in the electronic device 1, the protective housing 2 may include a housing 21 and a support assembly 22 disposed on the outside of the housing 21. The support assembly 22 may be generally annular. The electronic device 3 can be installed into the housing 21 from the inside of the protective housing 2, that is, the electronic device 3 can be installed on the side of the protective housing 2 facing away from the support assembly 22.

[0073] In this embodiment, the support assembly 22 can rotate relative to the housing 21, for example... Figure 3 This illustrates the state where the support assembly 22 is flipped and opened relative to the housing 21. (See diagram) Figure 2 and Figure 3 As shown, exemplary, the support assembly 22 can rotate downwards (or along) Figure 2 The bracket assembly 22 is opened by rotating counterclockwise (as shown in the image). It is understood that this embodiment does not limit the opening direction of the bracket assembly 22; for example, referring to... Figure 2 and Figure 3As shown, the pivot of the bracket assembly 22 can be adjusted upwards, allowing the bracket assembly 22 to rotate upwards (or along the axis of rotation). Figure 2 (Turn clockwise) to open.

[0074] like Figure 2 and Figure 3 As shown, for example, the support assembly 22 can rotate only about one axis to open or close, which may be, for example, parallel to a horizontal plane. In another embodiment, the support assembly 22 can rotate about two axes, where the first axis may be, for example, parallel to a horizontal plane, and the second axis may be, for example, along the thickness direction of the electronic device 3. Thus, the support assembly 22 can first rotate about the first axis to open, and then rotate about the second axis at a suitable angle so that the user can adjust the placement posture of the electronic device 3. For example, the user can initially place the electronic device 3 vertically, and then rotate the opened support assembly 22 about 90° about the second axis to place the electronic device 3 horizontally.

[0075] like Figure 1 and Figure 2 As shown, the electronic device 3 can have a built-in wireless charging module 31 for receiving electrical energy output from the wireless charger to achieve wireless charging. The wireless charging module 31 includes a charging coil (shown as a dashed circle in the figure), and the area where the charging coil is located is the effective wireless charging area of ​​the electronic device 3. Figure 2 As shown, the support assembly 22 may overlap with the effective area. The support assembly 22 is mainly made of conductive material, such as metal. By arranging the support assembly 22 in a ring shape, the overlap area between the support assembly 22 and the effective area can be minimized, thereby reducing the coupling of the metal material with the alternating magnetic field of the effective area and thus reducing the adverse effects of the metal material on wireless charging. It is understood that... Figure 2 The relative position of the central support assembly 22 to the effective area is merely an example and is not a limitation of this embodiment.

[0076] Figure 4 This illustration shows the assembly structure of the protective shell 2 in one embodiment. Figure 5 It indicated Figure 4 The three-dimensional structure of the shell 21 in the middle, Figure 6 It indicated Figure 4 The assembly structure of the support component 22 in the middle, Figure 7 It indicated Figure 6 The disassembled structure of the support assembly 22 in the middle, Figure 8 It indicated Figure 6 The assembly structure of the support component 22 in another view.

[0077] like Figure 5As shown, exemplarily, the outer side of the housing 21 may be provided with an annular groove 21a for accommodating the annular bracket in the bracket assembly 22 (described further below). The outer side of the housing 21 may also be provided with two shoulders 211 for mounting the rotating shaft in the bracket assembly 22 (described further below). Exemplarily, the position of the rotating shaft in the bracket assembly 22 is fixed to the housing 21, so that the bracket assembly 22 can only rotate about one axis to open or close.

[0078] like Figures 6-8 As shown, exemplarily, the support assembly 22 may include an annular support 221, a connecting portion 222, an insulating portion 223, a hinge 224, and a rotating shaft 225. Wherein, Figure 7 Due to the limited field of view, only a portion of the structure of the isolation section 223 is shown. Its detailed structure is as follows: Figure 12 and Figure 13 As shown below. Each will be explained in detail below.

[0079] Figure 9 and Figure 10 The three-dimensional structure of the ring-shaped support 221 is illustrated from different perspectives. For example... Figure 9 and Figure 10 As shown, the annular support 221 is generally annular, such as a circular ring or any other suitable shape, such as an elliptical ring, a square ring, a trapezoidal ring, etc. The circumferential and axial directions of the annular support 221 can be defined. The circumferential direction is the direction in which the annular support 221 extends around the perimeter, and the axial direction is perpendicular to the extension plane of the annular support 221.

[0080] Figure 9 and Figure 10 As shown, the annular support 221 has an opening 221b that breaks the annular support 221, making it a non-closed ring, or in other words, the annular support 221 forms a non-closed ring. Exemplarily, the annular support 221 may also have a groove 221a, with the opening 221b penetrating the bottom of the groove 221a. The groove 221a is used to accommodate the insulating portion 223 and the hinge member 224.

[0081] For example, the width of the opening 221b can be 0.5mm to 5mm, such as 0.5mm to 2mm, and can be 0.5mm, 1mm, 2mm, 3mm, 5mm, etc., as needed. By setting the width of the opening 221b within this range, manufacturing and assembly errors of the various components of the bracket assembly 22 can be covered, and deformation of the bracket assembly 22 during operation can also be taken into account, ensuring that the annular bracket 221 remains open rather than closed, so as to ensure that the annular bracket 221 does not form a closed conductive circuit when the electronic device 3 with the protective case 2 is wirelessly charged. This point will be further explained below.

[0082] In this embodiment, the annular support 221 is a conductor, for example, made of a metal material such as aluminum alloy.

[0083] like Figure 9 As shown, for example, the connecting part 222 can be a riveted post structure, and the connecting part 222 can be integrated with the annular bracket 221. The connecting part 222 can be provided on the bottom surface of the groove 221a. Several connecting parts 222 can be provided, for example, two on each side of the opening 221b. Alternatively, the connecting part 222 can also be independent of the annular bracket 221. The connecting part 222 is not limited to a riveted post, but can be a screw, bolt or other connecting component.

[0084] The connecting part 222 is a conductor, for example, made of a metallic material.

[0085] like Figure 6 and Figure 7 As shown, the connecting portion 222 is used to fix the annular bracket 221, the insulating portion 223, and the hinge 224. Exemplarily, the connecting portion 222 can be used to connect the annular bracket 221, the insulating portion 223, and the hinge 224 using a riveting process. In another embodiment, the connecting portion 222 may be omitted, and the annular bracket 221, the insulating portion 223, and the hinge 224 can be fixedly connected using any suitable process, such as welding, bonding, or snap-fitting. This application embodiment does not limit this. The following description will continue with an example where the bracket assembly 22 includes the connecting portion 222.

[0086] Figure 11 The three-dimensional structure of hinge 224 is illustrated. For example... Figure 11 As shown, the hinge 224 may include a connected plate-like portion 224a and a wound portion 224f.

[0087] like Figure 11 As shown, the plate-like portion 224a can be or approximately plate-shaped, and it may include a first surface 224b, a side surface 224c, and a second surface 224d, with the three surfaces connected sequentially. The normals of the first surface 224b and the second surface 224d can be substantially along the thickness direction of the plate-like portion 224a, and these normals can also be along the axial direction of the annular support 221. Figure 11 and Figure 9 As shown, the first surface 224b is used for assembly with the bottom surface of the groove 221a of the annular support 221.

[0088] like Figure 11As shown, the plate-shaped portion 224a may have a plurality of through holes 224e, for example, four through holes 224e, which may be respectively provided at opposite ends of the plate-shaped portion 224a. The through holes 224e penetrate through the first surface 224b and the second surface 224d. The through holes 224e are used for the connecting portion 222 to pass through, so that the plate-shaped portion 224a is fixed to the annular bracket 221.

[0089] like Figure 11 As shown, the winding portion 224f can be coiled, which is used to form a rotational engagement with the rotating shaft 225, allowing the hinge 224 to rotate about the rotating shaft 225. For example, the rotational friction between the winding portion 224f and the rotating shaft 225 can be relatively large; for instance, they can form an interference fit, so that the hinge 224 can be suspended during rotation, allowing the annular support 221 to unfold to a set angle or any angle. In another embodiment, the winding portion 224f can be fixedly connected to the rotating shaft 225, which is rotatably connected to the housing 21, thereby causing the hinge 224 and the rotating shaft 225 to rotate together relative to the housing 21.

[0090] The hinge 224 is a conductor, and its material is, for example, a metallic material, such as steel.

[0091] The above description of the structure of hinge 224 is merely an example. In reality, the structure of hinge 224 is not limited to this; it is sufficient as long as it can connect the ring bracket 221 and the pivot 225.

[0092] refer to Figure 6 and Figure 7 As shown, in this embodiment, the insulating part 223 can be integrated with the hinge 224. The two are not connected by assembly, but rather the insulating part 223 is integrally formed on the hinge 224 through a certain process. The insulating part 223 is made of insulating material.

[0093] For example, molten plastic material can be bonded to the surface of the hinge 224 using an insert injection molding process, and the insulating part 223 is formed after the plastic cures. The plastic material includes, but is not limited to, a combination of polycarbonate (PC) and glass fiber (GF), or a combination of polypropylene (PP) and GF.

[0094] Alternatively, an insulating material can be coated onto the surface of the hinge 224 using a coating process, and the insulating part 223 can be formed after the insulating material cures. The insulating material may include, but is not limited to, epoxy resin. Alternatively, the insulating part 223 can be integrally formed onto the surface of the hinge 224 using other suitable processes, such as oxidation, physical vapor deposition (PVD), or electroless plating.

[0095] It is understandable that the insulating portion 223 formed by the above-described integrated process can be used... Figures 6-7 And what will be described below Figures 16-18 An example is provided.

[0096] It is understandable that, since the isolating part 223 is integrally formed on the surface of the hinge 224, the structure of the isolating part 223 is dependent on the structure of the hinge 224, and the isolating part 223 and the hinge 224 cannot be disassembled by non-destructive means. However, in order to illustrate the structure of the isolating part 223 in this embodiment, by... Figure 12 and Figure 13 The isolation section 223 is shown separately.

[0097] like Figure 12 and Figure 13 As shown, the insulating portion 223 may include a first layer 223b and a second layer 223c, which are stacked with an interval between them. Both the first layer 223b and the second layer 223c can be sheet-like structures. The insulating portion 223 may also include a cylindrical structure 223a connecting the first layer 223b and the second layer 223c. For example, there may be multiple cylindrical structures 223a, which may be located at opposite ends of the first layer 223b.

[0098] Figure 14 The positional relationship between the insulating part 223 and the hinge member 224 is illustrated. For example... Figure 14 As shown, the first layer 223b of the insulating portion 223 can cover the entire area of ​​the second surface 224d of the hinge 224, the second layer 223c of the insulating portion 223 can cover the entire area of ​​the first surface 224b of the hinge 224, and each cylindrical structure 223a of the insulating portion 223 can cover the inner wall of a through hole 224e of the hinge 224.

[0099] like Figure 14 As shown, for example, the insulating portion 223 may not cover the side surface 224c of the hinge member 224, and the side surface 224c may be exposed. This design makes the insulating portion 223 easier to manufacture. In another embodiment, the insulating portion 223 may also cover the side surface 224c, which can be achieved by adjusting the manufacturing process of the insulating portion 223.

[0100] The structure of each component in the bracket assembly 22 has been described above. The assembly relationship of each component in the bracket assembly 22 and the assembly relationship between the bracket assembly 22 and the housing 21 will be described below.

[0101] Figure 15 for Figure 6 The schematic diagram of the AA section structure of the support assembly 22 is shown in the figure. The section AA is composed of multiple non-coplanar sections connected together. Figure 16 for Figure 15 A magnified schematic diagram of the structure at point B in the middle.

[0102] like Figure 15 and Figure 16 As shown, the insulating portion 223 and the hinge 224 can be mounted on the annular bracket 221, for example, within the groove 221a. The second layer 223c of the insulating portion 223 can contact the bottom wall of the groove 221a, that is, the second layer 223c isolates the annular bracket 221 from the hinge 224 (or the plate-like portion 224a of the hinge 224) (referring to electrical isolation, the same below). The side surface 224c of the hinge 224 can have a gap with the side surface of the groove 221a, or in other words, the side surface 224c can have a gap with the annular bracket 221.

[0103] Combination Figure 16 and Figure 14 As shown, the connecting part 222 can pass through the through hole 224e of the hinge 224 and fix the annular bracket 221, the isolating part 223 and the hinge 224. It can be understood that the cylindrical structure 223a of the isolating part 223 isolates the inner wall of the through hole 224e from the connecting part 222, and therefore also isolates the inner wall of the through hole 224e from the annular bracket 221.

[0104] As described above, for example, the connecting part 222 can be a riveting post, which can connect the annular bracket 221, the insulating part 223 and the hinge member 224 through a riveting process. Figure 17 and Figure 18 The riveting principle is illustrated, in which... Figure 17 This diagram illustrates the state of the riveted connection parts 222. Figure 17 This illustration shows the state after the connecting part 222 is riveted. For example... Figure 17 and Figure 18 As shown, during the riveting process, the top end of the connecting part 222 can be extended and deformed to connect with the insulating part 223, and finally the insulating part 223, the hinge 224 and the annular bracket 221 are fixed together.

[0105] like Figure 16As shown, the isolating portion 223 isolates the lower surface of the hinge member 224 (i.e., the first surface 224b mentioned above) from the annular bracket 221; isolates the inner wall of the through hole 224e of the hinge member 224 from the annular bracket 221; and isolates the upper surface of the hinge member 224 (i.e., the second surface 224d mentioned above) from the connecting portion 222, thereby isolating the upper surface from the annular bracket 221. Therefore, the isolating portion 223 is used to achieve electrical isolation between the hinge member 224 and the annular bracket 221. In addition, the side surface 224c of the hinge member 224 and the annular bracket 221 have a gap, so that the two are not electrically connected.

[0106] like Figure 6 As shown, the pivot 225 can pass through the winding portion 224f of the hinge 224 and is rotatably connected to the winding portion 224f. Figure 6 and Figure 5 As shown, the rotating shaft 225 can be fixed to the shoulder 211 of the housing 21. Thus, the bracket assembly 22 and the housing 21 are rotatably connected.

[0107] As can be understood from the above, in another embodiment, the rotating shaft 225 can be fixedly connected to the winding portion 224f, and the rotating shaft 225 can be rotatably connected to the shoulder 211, thus also realizing the rotatable connection between the bracket assembly 22 and the housing 21.

[0108] The following will combine Figures 19-21 This explains the principle that by electrically isolating the hinge 224 from the annular bracket 221, the adverse effects of the bracket assembly 22 on wireless charging can be reduced or avoided.

[0109] refer to Figure 2 As shown, electronic device 3 can be wirelessly charged with protective case 2.

[0110] refer to Figure 19 and Figure 20 As shown, because the annular bracket 221 has an opening 221b, when the electronic device 3 can be wirelessly charged with the protective case 2, the annular bracket 221 itself cannot form a closed conductive circuit. This means... Figure 19 and Figure 20 The “X” symbol at the opening 221b is used to refer to it.

[0111] refer to Figure 19 and Figure 21 As shown, by electrically isolating the hinge 224 from the annular support 221 as described above, the connecting part 222 cannot be connected to the hinge 224. Therefore, the hinge 224 cannot connect the portions of the annular support 221 located on both sides of the opening 221b, that is, the hinge 224 cannot form a closed conductive circuit with the annular support 221. This meaning is represented by the "X" symbol between the connecting part 222 and the hinge 224.

[0112] Therefore, by providing the isolation part 223, this embodiment electrically isolates the hinge 224 from the annular bracket 221, thus preventing the formation of a closed conductive loop in the bracket assembly 22. Even if the bracket assembly 22 overlaps with the effective area of ​​wireless charging, the bracket assembly 22 will not couple with the alternating magnetic field of wireless charging to consume charging power, which helps ensure charging efficiency. Furthermore, the temperature rise of the bracket assembly 22 during wireless charging is small, which helps reduce the probability of FOD response of the wireless charging base and helps ensure that the electronic device 3 charges with a larger charging power. Since the heat generation of the bracket assembly 22 is reduced, it also ensures that the electronic device 3 can be wirelessly charged more safely.

[0113] The conventional approach is to fill the opening 221b of the annular support 221 with plastic to prevent the formation of a closed conductive loop in the annular support 221. This approach results in poor structural strength and rigidity, reduces structural reliability, and also leads to inconsistent appearance. Moreover, considering the processability of filling the opening 221b with plastic, the opening 221b needs to be set relatively large, which not only affects structural reliability but also results in a poor aesthetic appearance.

[0114] In contrast, in this embodiment, after the annular bracket 221 is broken to form an opening 221b, plastic is not filled into the opening 221b. Instead, the hinge 224 spans the opening 221b, and the connecting part 222 is used to fix the hinge 224 and the annular bracket 221 together. This ensures the rigidity and structural strength of the bracket assembly 22, thereby guaranteeing the mechanical reliability of the bracket assembly 22. This embodiment allows most of the structure of the bracket assembly 22 to be made of metal, which can improve the structural strength and rigidity of the bracket assembly 22, ensure its mechanical reliability, and also give the bracket assembly 22 a more uniform appearance, improving its aesthetic appeal. Furthermore, since only the opening 221b is provided without filling it with plastic, there is no need to consider the processing requirements for filling with plastic, allowing the opening 221b to be made smaller. This is beneficial for improving the appearance quality of the bracket assembly 22, especially enhancing the appearance of the outer surface of the protective shell 2 (e.g., Figure 1 (As shown).

[0115] Based on the embodiments described above, such as Figure 9 As shown, exemplarily, an insulating material layer 221c (shown in shaded area) can also be provided in the region where the annular support 221 connects to the hinge 224. This insulating material layer 221c has insulating properties and is used to enhance the electrical isolation between the annular support 221 and the hinge 224. Furthermore, this insulating material layer 221c can still ensure the electrical isolation between the annular support 221 and the hinge 224 even after the insulating portion 223 is damaged.

[0116] For example, the insulating material layer 221c can cover the entire inner surface of the groove 221a and the entire surface of the connecting portion 222.

[0117] For example, a deep anodizing process can be used to form an oxide layer with a thickness of 20 μm to 150 μm. The thickness of this oxide layer can be, for example, 20 μm, 25 μm, 30 μm, 60 μm, 100 μm, 135 μm, 150 μm, etc. This oxide layer serves as the insulating material layer 221c. Alternatively, the insulating material layer 221c can also be formed using PVD, chemical plating, or other methods.

[0118] Based on the embodiments described above, the isolation portion 223 can be adjusted to obtain the following embodiments. These will be explained below.

[0119] Figure 22 The diagram illustrates the structure of the isolation portion 233 in another embodiment before assembly. For example... Figure 22 As shown, unlike the embodiments described above, the isolating part 233 in this embodiment is a component independent of the hinge member 224. The isolating part 233 may include a first sub-isolating part 233b and a second sub-isolating part 233d. Both the first sub-isolating part 233b and the second sub-isolating part 233d can be sheet-like structures and can be arranged opposite to each other. The first sub-isolating part 233b may have a plurality of through holes 233a, and the second sub-isolating part 233d may have a plurality of through holes 233c, each through hole 233c being aligned with one through hole 233a. The diameter of the through hole 233c may be smaller than the diameter of the through hole 233a.

[0120] Similar to Figure 16 The viewpoint and display range, Figure 23 A cross-sectional assembly diagram illustrating the annular support 221, connecting portion 222, insulating portion 233, and hinge member 224 is shown. Figure 23 As shown, the connecting part 222 can be a riveted post structure, which can be integrated with the annular bracket 221. However, for the sake of illustrating the principle, the connecting part 222 and the annular bracket 221 are shown with different shades. In addition, the second sub-isolating part 233d, the through hole 233c, the first sub-isolating part 233b, and the through hole 233a are marked in several places.

[0121] refer to Figure 23As shown, the annular bracket 221, the first sub-isolating portion 233b, the hinge 224, and the second sub-isolating portion 233d can be stacked sequentially. The first sub-isolating portion 233b can cover the entire area of ​​the first surface 224b of the hinge 224, and the second sub-isolating portion 233d can cover the entire area of ​​the second surface 224d of the hinge 224. Each connecting portion 222 can pass through a through hole 233a on the first sub-isolating portion 233b and a through hole 224e on the hinge 224 (combined with...). Figure 14 As shown, the ring bracket 221, the first sub-isolation part 233b, the hinge 224, and the second sub-isolation part 233d are fixedly connected by a riveting process. During the riveting process, the head of the connecting part 222 deforms and presses the second sub-isolation part 233d to bend it, ultimately connecting the second sub-isolation part 233d with the first sub-isolation part 233b and covering the inner wall of the through hole 224e of the hinge 224. Thus, the isolation part 233 can electrically isolate the hinge 224 from the ring bracket 221.

[0122] like Figure 23 As shown, for example, the isolating portion 233 does not cover the side surface 224c of the hinge 224, and the side surface 224c may have a gap with the annular support 221 to prevent them from communicating. In another embodiment, the isolating portion 233 may also cover the side surface 224c of the hinge 224, for example, by a first sub-isolating portion 233b or a second sub-isolating portion 233d covering the side surface 224c.

[0123] Figure 22 and Figure 23 The embodiment shown can also achieve the purpose of avoiding the formation of a closed conductive circuit without filling the opening 221b with plastic, which can ensure the efficiency and safety of wireless charging, improve the structural strength and rigidity of the bracket assembly 22, ensure the mechanical reliability of the bracket assembly 22, and also help to give the bracket assembly 22 a uniform appearance and improve the appearance and texture of the bracket assembly 22.

[0124] Based on the above Figure 22 and Figure 23 The embodiment shown can be modified by adjusting the structure of the second sub-insulating portion 233d to obtain another embodiment. The following will be combined with... Figure 24 and Figure 25 Please provide an explanation.

[0125] Figure 24 A cross-sectional view of the second sub-isolation portion 233d in another embodiment is illustrated. For example... Figure 24As shown, the second sub-isolating part 233d is no longer a sheet-like structure, but rather resembles a sleeve or nut, and its cross-section can be approximately C-shaped, for example. The second sub-isolating part 233d has a through hole 233c.

[0126] Figure 25 This diagram illustrates a cross-sectional assembly structure of the annular support 221, connecting portion 222, insulating portion 233, and hinge member 224 in this embodiment. Figure 25 As shown, there can be multiple second sub-isolating portions 233d, each of which is fitted around the outer periphery of a connecting portion 222. Each second sub-isolating portion 233d is connected to a first sub-isolating portion 233b, and all the second sub-isolating portions 233d and the first sub-isolating portion 233b together cover the first surface 224b of the hinge member 224. Each second sub-isolating portion 233d covers a partial area of ​​the second surface 224d of the hinge member 224, and also covers the through hole 224e of the hinge member 224 (in conjunction with...). Figure 14 The inner wall of (as shown). Thus, the insulating part 233 can electrically isolate the hinge 224 from the annular support 221.

[0127] For example, refer to Figure 25 and Figure 7 As shown, during assembly, the first sub-isolating part 233b can be positioned on the annular bracket 221 first, so that the connecting part 222 passes through the through hole of the first sub-isolating part 233b. Then, the second sub-isolating part 233d is inserted into the through hole 224e of the hinge 224 (connecting). Figure 14 As shown, the second sub-isolating portion 233d covers the inner wall of the through hole 224e. Then, the second sub-isolating portion 233d and the hinge 224 are positioned on the first sub-isolating portion 233b, such that the connecting portion 222 passes through the through hole 224e, and the second sub-isolating portion 233d is connected to the first sub-isolating portion 233b. Finally, the connecting portion 222 is fixedly connected to the second sub-isolating portion 233d, the hinge 224, the first sub-isolating portion 233b, and the annular bracket 221 by riveting. It is understood that the above assembly method is merely an example; in practice, any suitable assembly method can be used as needed.

[0128] like Figure 25 As shown, for example, the isolating portion 233 does not cover the side surface 224c of the hinge 224, and the side surface 224c may have a gap with the annular support 221 to prevent them from communicating. In another embodiment, the isolating portion 233 may also cover the side surface 224c of the hinge 224, for example, by the first sub-isolating portion 233b covering the side surface 224c.

[0129] Figure 24 and Figure 25The illustrated embodiment also achieves the goal of avoiding the formation of a closed conductive circuit without filling the opening 221b with plastic, ensuring the efficiency and safety of wireless charging, improving the structural strength and rigidity of the bracket assembly 22, ensuring the mechanical reliability of the bracket assembly 22, and also contributing to a uniform appearance and improved aesthetics of the bracket assembly 22. Furthermore, this embodiment only requires direct assembly of the second sub-isolating part 233d to achieve connection with the first sub-isolating part 233b, eliminating the need for secondary processing such as riveting, thus improving production efficiency.

[0130] In all the above embodiments, the hinge 224 is covered by an insulating portion to achieve electrical isolation between the hinge 224 and the annular support 221, thereby preventing the formation of a closed conductive loop in the support assembly 22. Several other embodiments using different structures to prevent the formation of a closed conductive loop in the support assembly 22 are listed below.

[0131] Figure 26 The assembly structure of the support assembly 32 in another embodiment is illustrated. For example... Figure 26 As shown, the support assembly 32 may include an annular support 321, a first sub-shaft 322, two hinges 323, and a second sub-shaft 324.

[0132] like Figure 26 As shown, the annular support 321 may have an opening 321a, which breaks the annular support 321, making it a non-closed ring, or in other words, the annular support 321 forms a non-closed ring. Exemplarily, two hinged portions 323 may be integrally connected to the annular support 321, and may be located on opposite sides of the opening 321a, with a gap between them. Alternatively, in another embodiment, the two hinged portions 323 may also be connected to the annular support 321 through assembly.

[0133] like Figure 26 As shown, the first sub-shaft 322 and the second sub-shaft 324 can each be connected to a hinge portion 323, for example, forming a rotatable connection, wherein both the first sub-shaft 322 and the second sub-shaft 324 can be fixed to the housing of the protective shell; or, they can form a fixed connection, wherein both the first sub-shaft 322 and the second sub-shaft 324 are rotatably connected to the housing of the protective shell. The first sub-shaft 322 and the second sub-shaft 324 have a gap.

[0134] In this embodiment, the first sub-shaft 322 and the second sub-shaft 324 can be collectively referred to as rotating shafts.

[0135] Figure 26In the illustrated embodiment, because the annular support 321 has an opening 321a, the annular support 321 itself cannot form a closed conductive loop. Because the first sub-shaft 322 and the second sub-shaft 324 have a gap, the annular support 321 also cannot form a closed conductive loop through the first sub-shaft 322 and the second sub-shaft 324. Therefore, even if the support assembly 32 overlaps with the effective area of ​​wireless charging, the support assembly 32 will not couple with the alternating magnetic field of wireless charging to consume charging power, which is beneficial to ensuring charging efficiency. Furthermore, the temperature rise of the support assembly 32 during wireless charging is small, which helps reduce the probability of FOD response of the wireless charging base and helps ensure that electronic devices are charged with a larger charging power. Reducing the heat generation of the support assembly 32 also ensures that electronic devices can be wirelessly charged more safely. In addition, all components of the support assembly 32 can be made of metal, which helps ensure the mechanical reliability of the support assembly 32, allows the support assembly 32 to have a uniform appearance, and improves the aesthetic texture of the support assembly 32.

[0136] Figure 27 The assembly structure of the support assembly 32 in another embodiment is illustrated. (Comparison) Figure 27 and Figure 26 As shown, with Figure 26 The difference between the embodiments shown is that, Figure 27 In the illustrated embodiment, the support assembly 32 includes a rotating shaft 325, which may comprise a first segment 325a, a second segment 325b, and a third segment 325c, connected sequentially. The first segment 325a and the third segment 325c are both conductors, for example, made of a metallic material; the second segment 325b is an insulator. Two hinge portions 323 are connected to the first segment 325a and the third segment 325c respectively, while the second segment 325b is not connected to either hinge portion 323.

[0137] Figure 27In the illustrated embodiment, because the annular support 321 has an opening 321a, the annular support 321 itself cannot form a closed conductive loop. Since the second segment 325b of the pivot 325 is an insulator, the two hinges 323 cannot conduct through the pivot 325, therefore the annular support 321 cannot form a closed conductive loop through the pivot 325. Therefore, even if the support assembly 32 overlaps with the effective area of ​​wireless charging, the support assembly 32 will not couple with the alternating magnetic field of wireless charging to consume charging power, which helps ensure charging efficiency. Furthermore, the temperature rise of the support assembly 32 during wireless charging is small, which helps reduce the probability of FOD response of the wireless charging base and helps ensure that electronic devices are charged with a larger charging power. Reducing the heat generated by the support assembly 32 also ensures that electronic devices can be wirelessly charged more safely. In addition, most of the structure of the support assembly 32 can be made of metal, which helps ensure the mechanical reliability of the support assembly 32, allows the support assembly 32 to have a more uniform appearance, and helps improve the appearance and texture of the support assembly 32.

[0138] Figure 28 The illustration shows the assembly structure of the support assembly 32 in another embodiment. (Compared to...) Figure 27 The difference between the embodiments shown is that, Figure 28 In the illustrated embodiment, each region of the shaft 326 is made of a conductive material, and the shaft 326 is a conductor. Furthermore, an insulating material layer 326a (shown in shaded area) is formed on the outer surface of the shaft 326. Exemplarily, this insulating material layer 326a may cover all or part of the circumferential surface of the shaft 326; alternatively, it may cover both the circumferential and axial surfaces of the shaft 326. The insulating material layer 326a has insulating properties. This insulating material layer 326a may be formed, including but not limited to, by oxidation, PVD, or chemical plating.

[0139] like Figure 28 As shown, both hinges 323 can be connected to the area of ​​the pivot 326 covered by the insulating material layer 326a. Therefore, the two hinges 323 cannot be connected through the pivot 326, and thus the annular support 321 cannot form a closed conductive loop through the pivot 326.

[0140] It is understood that by covering the pivot 326 with an insulating material layer 326a over as large an area as possible, it is beneficial to ensure that the two hinge portions 323 are always isolated by the insulating material layer 326a. For example, the insulating material layer 326a may not be formed on the pivot 326 itself, but rather in the connection area between the two hinge portions 323 and the pivot 326, which can also achieve electrical isolation. Alternatively, the insulating material layer 326a can be formed on both hinge portions 323 and the pivot 326 simultaneously to enhance the electrical isolation effect.

[0141] Figure 28 In the illustrated embodiment, because the annular support 321 has an opening 321a, the annular support 321 itself cannot form a closed conductive loop. Because the outer surface of the pivot 326 and / or the two hinge portions 323 are provided with an insulating material layer 326a, the two hinge portions 323 cannot conduct through the pivot 326, therefore the annular support 321 cannot form a closed conductive loop through the pivot 326. Therefore, even if the support assembly 32 overlaps with the effective area of ​​wireless charging, the support assembly 32 will not couple with the alternating magnetic field of wireless charging to consume charging power, which is beneficial to ensuring charging efficiency. Furthermore, the temperature rise of the support assembly 32 during wireless charging is small, which helps reduce the probability of FOD response of the wireless charging base and helps ensure that electronic devices are charged with a larger charging power. Reducing the heat generation of the support assembly 32 also ensures that electronic devices can be wirelessly charged more safely. In addition, most of the structure of the support assembly 32 can be made of metal, which helps ensure the mechanical reliability of the support assembly 32, allows the support assembly 32 to have a more uniform appearance, and helps improve the appearance and texture of the support assembly 32.

[0142] Based on any of the above embodiments, a cover can also be provided in the bracket assembly to cover the internal components of the bracket assembly, so that when the bracket assembly is opened relative to the housing 21, the inner surface of the bracket assembly has a more integrated appearance. The bracket assembly 22 described above will be described below as an example.

[0143] like Figure 29 and Figure 30 As shown, the support assembly 22 may further include a cover 226, which may be a closed ring or a sheet-like structure. The cover 226 may cover the annular support 221, the connecting portion 222, and the insulating portion 223. The portion of the pivot 225 and the hinge 224 through which it passes may not be covered by the cover 226.

[0144] For example, such as Figure 30 As shown, along the circumference of the annular support 221, the portion of the annular support 221 other than the groove 221a may have a groove 221d. A portion of the cover 226 is located within the groove 221d, and another portion is located in the area where the groove 221a is located. The cover 226 may be flush with or substantially flush with the annular support 221.

[0145] like Figure 31As shown, when the bracket assembly 22 is flipped open relative to the housing 21, the cover 226 can face outwards, and the connecting portion 222 and the insulating portion 223 located inside are covered by the cover 226. Therefore, the inner surface of the bracket assembly 22 has a relatively integrated appearance. It can be understood that when the bracket assembly 22 is closed relative to the housing 21, the cover 226 is located on the side of the hinge 224 facing the housing 21, or in other words, it is located between the annular bracket 221 and the housing 21.

[0146] refer to Figure 30 As shown, in another embodiment, the shape of the cover 226 can be adjusted so that the cover 226 is no longer a closed ring, but only a segment of a closed ring. The cover 226 may only cover the connecting portion 222 and the insulating portion 223, without covering the annular support 221; or it may cover the connecting portion 222 and the insulating portion 223, and cover a portion of the annular support 221.

[0147] For example, in this embodiment, the edge of the cover 226 may be flush with or substantially flush with the annular bracket 221. This approach can also improve the integrated appearance of the inner side of the bracket assembly 22 to some extent.

[0148] Based on the above, it can be understood that, for Figures 26-28 The bracket assembly 32 shown can also be provided with a cover. This cover can be a closed ring that covers the annular bracket 321; or, the cover can be a segment of the closed ring that only covers the area of ​​the annular bracket 321 with the opening 321a. This improves the integrated appearance of the inner surface of the bracket assembly 32.
