[0047] It should also be noted that the division of multiple embodiments in this utility model is only for the convenience of description and should not constitute a special limitation. Features in various embodiments can be combined and referenced in each other without contradiction.

[0048] This utility model provides an electronic device accessory, as shown in the following embodiment. Figure 1 and Figure 2 The electronic device accessory includes a main body 10 and a bracket assembly mounted on the main body 10. The main body 10 has a camera avoidance hole 112. The bracket assembly includes an annular base 20, a hinge structure 30, and a support member 40. The annular base 20 is mounted on the main body 10. (See reference...) Figure 3 The annular base 20 is a non-metallic structure and has a first opening 21. The first opening 21 extends through the annular base 20 along its axial direction, and also extends radially through at most one of the inner and outer sides of the annular base 20. (Refer to...) Figure 4 and Figure 5 The hinge structure 30 includes a metal bearing 31 and a pivot 32. The metal bearing 31 is disposed within the first opening 21 and fixedly connected to the annular base 20. The pivot 32 is connected to the metal bearing 31. The support member 40 is connected to the hinge structure 30 and rotatably connected to the annular base 20 via the pivot 32. The support member 40 (support assembly) has a retracted state and a supported state. In the retracted state, the support member 40 and the annular base 20 are extended relative to each other. The support member 40 is positioned corresponding to the camera avoidance hole 112, so that the support member 40 can not only be offset from the wireless charger but also protect the camera of the electronic device. Specifically, the support member 40 can be arranged around the camera avoidance hole 112, or located inside the camera avoidance hole 112, or covering the camera avoidance hole 112. In the supported state, the support member 40 and the annular base 20 form a certain angle, thereby supporting the electronic device.

[0049] Specifically, electronic device accessories can be protective cases with stands, the main body 10 can be the casing of the protective case, and the electronic device can be a mobile phone, tablet computer, etc. (See reference) Figure 1 For example, the main body 10 includes a back panel 11 and a side frame 12, which together enclose a receiving cavity for accommodating a mobile phone (corresponding electronic device).

[0050] The bracket assembly is located on the back of the main body 10 (i.e., the surface facing away from the receiving cavity). The shape of the support member 40 is designed according to the shape of the camera / camera clearance hole 112 of the electronic device accessory, for example, it can be... Figure 1 The circular shape in the middle can also be Figure 14 The track-shaped ring, etc.

[0051] Specifically, the main body 10 is also provided with a support mounting groove 113, which is arranged around the camera avoidance hole 112. In the stored state, the support 40 is located inside the support mounting groove 113 and works with the camera avoidance hole 112 to protect the camera of the electronic device.

[0052] The annular base 20, for example, is positioned on the main body 10 in the area corresponding to the wireless charging area. It is made of non-metallic materials such as fiberglass or plastic to minimize interference with wireless charging. The term "annular" can refer to a circular ring, a square ring, or other irregular rings; generally, it is set to a circular shape to match the wireless charging area. The axis of the annular base 20 refers to the direction in which the top and bottom surfaces face each other. For example, if the bottom surface of the annular base 20 is connected to the main body 10, and the top surface faces away from the main body 10, the axis of the annular base 20 is also perpendicular to the back plate 11. Figure 3As shown, the first opening 21 is positioned such that the outer side of the annular base 20 is disconnected, but the inner side remains open. In some embodiments, the position of the first opening 21 can be adjusted so that the inner side is disconnected, but the outer side remains open, or the first opening 21 can be located between the inner and outer sides of the annular base 20, with neither side remaining open. All these positions of the first opening 21 ensure that it penetrates at most one of the inner or outer sides of the annular base 20 radially. Since the annular base 20 is a non-metallic structure, it avoids interference with wireless charging. The fact that the first opening 21 does not penetrate the inner and / or outer sides of the annular base 20 allows it to remain a relatively complete annular structure, providing higher strength compared to a structure where both the inner and outer sides are disconnected into arc shapes. Furthermore, the axial penetration of the first opening 21 allows the metal bearing 31 to be set to approximately the same thickness as the annular base 20, ensuring the thickness guarantees the strength of the metal bearing 31. The metal bearing seat 31 can be made of stainless steel. Using a metal material for the metal bearing seat 31, which connects to the pivot 32, ensures high strength in the hinge structure 30. The pivot 32 can also be made of a metal material, for example, the same material as the metal bearing seat 31. The support member 40 can be made of aluminum.

[0053] In this embodiment of the invention, by setting the annular base 20 as a special non-metallic structure and matching it with the metal bearing 31, the impact on wireless charging can be reduced while ensuring the strength of the hinge structure 30, thus achieving stable support.

[0054] In some embodiments, refer to Figure 4 and Figure 5 The rotating shaft 32 includes a first end 321 and a second end 322 opposite to each other. The metal bearing 31 includes a first bushing portion 311 and a second bushing portion 312, which are arranged opposite to each other along the axial direction of the rotating shaft 32 and respectively sleeve and fix the first end 321 and the second end 322. The first bushing portion 311 has a first shaft hole 3111 that matches one end of the rotating shaft 32. The second bushing portion 312 has a second shaft hole 3121 that matches the second end 322. A second opening 315 is formed between the first bushing portion 311 and the second bushing portion 312. The support member 40 is rotatably connected to the portion of the rotating shaft 32 located within the second opening 315. The first bushing portion 311 and the second bushing portion 312 at both ends of the metal bearing 31 can fix the rotating shaft 32, ensuring a stable connection. The rotatable connection between the support member 40 and the middle portion of the rotating shaft 32 ensures a certain contact area for better force distribution and a more stable structure.

[0055] In some embodiments, such as Figure 2As shown, the first opening 21 penetrates the outer side of the annular base 20, or in other words, the first opening 21 is located on the side of the annular base 20 near the outer side of the ring. Specifically, the annular base 20 includes a first sidewall 201 located between the inner and outer sides of the ring, and a second sidewall 202 and a third sidewall 203 located at opposite ends of the first sidewall 201 along the axial direction of the pivot 32. The first sidewall 201, the second sidewall 202, and the third sidewall 203 together enclose the first opening 21. The first sidewall 201 contacts the side of the metal bearing 31 away from the second opening 315, the second sidewall 202 contacts the side of the first bushing portion 311 away from the second bushing portion 312, and the third sidewall 203 contacts the side of the second bushing portion 312 away from the first bushing portion 311. This arrangement allows the support member 40 to unfold better, avoids interference between the hinge structure 30 and the outer side of the annular base 20, and allows the overall electronic device components to be thinner.

[0056] In some embodiments, refer to Figure 5 and Figure 8 The second end 322 has a flat portion. The flat portion passes through the second shaft hole 3121 to restrict the rotation of the shaft 32 relative to the second shaft hole 3121. Specifically, the flat portion has two opposing surfaces recessed relative to the surface of the shaft 32, and the distance between the two opposing surfaces is the thickness of the flat portion, meaning the thickness of the flat portion is less than the diameter of the shaft 32. The shape of the second shaft hole 3121 matches the shape of the flat portion and also has two opposing planes, preventing the flat portion from rotating relative to the second shaft hole 3121. Therefore, by providing a flat portion at the second end 322, better restriction of the shaft 32 can be achieved to prevent rotation of the shaft 32 relative to the metal bearing 31.

[0057] In some embodiments, the first shaft hole 3111 extends through the first bushing portion 311 along the axial direction of the rotating shaft 32. This makes it easier to assemble the hinge structure by inserting the rotating shaft 32 from the end of the first shaft hole 3111 away from the second shaft hole 3121, starting from the second end 322, until the second end 322 extends into the second shaft hole 3121.

[0058] In some embodiments, continue to refer to Figure 8 The length of the portion of the rotating shaft 32 located within the first shaft hole 3111 is less than the length of the first shaft hole 3111, and the annular base 20 is at least partially embedded within the first shaft hole 3111. This allows the annular base 20 and the metal shaft seat 31 to partially interlock, ensuring a more stable connection and increasing the overall strength of the support assembly.

[0059] Similarly, in some embodiments, the second shaft hole 3121 extends through the second bushing portion 312 along the axial direction of the rotating shaft 32, and the length of the portion of the rotating shaft 32 located within the second shaft hole 3121 is less than the length of the second shaft hole 3121. The annular base 20 is at least partially embedded within the second shaft hole 3121. This also allows the annular base 20 and the metal bearing 31 to partially engage with each other, ensuring a more stable connection and increasing the overall strength of the support assembly.

[0060] In some embodiments, the metal bearing 31 is formed with a protrusion 313 (see reference). Figure 5 A recessed portion 22 is formed on the annular base 20 (see reference). Figure 3 The protrusion 313 is embedded in the recess 22. This also allows the annular base 20 and the metal bearing 31 to partially interlock, ensuring a more stable connection and increasing the overall strength of the support assembly.

[0061] In some embodiments, the metal bearing 31 is provided with a positioning part 314, which has a positioning hole 3141. This allows for better positioning of the metal bearing 31 when it is assembled with the annular base 20.

[0062] In some embodiments, the metal bearing seat 31 and the annular base 20 are integrally molded inserts. In actual production, the metal bearing seat 31 can be placed into the molding die of the annular base 20 and then injection molded into the die to form the metal bearing seat 31 and the annular base 20 as an insert.

[0063] In some embodiments, refer to Figure 5 The hinge structure 30 also includes a first connector 33, which includes a connecting portion 331 and a third bushing portion 332. The connecting portion 331 is fixedly connected to the support member 40. The third bushing portion 332 bends and extends to form a third shaft hole 3321. The third bushing portion 332 is rotatably connected to the rotating shaft 32 within the second opening 315, that is, the rotating shaft 32 passes through the third shaft hole 3321 and is rotatably connected to the third bushing portion 332. The first connector 33 can be made of metal, for example, and can be made of the same material as the rotating shaft 32. The connecting portion 331 is, for example, plate-shaped and has multiple riveting holes for riveting and fixing to the support member 40.

[0064] In some embodiments, the first connector 33 is an integral metal injection molded structure. That is, the first connector 33 is manufactured using the MIM (metal injection molding) process, which, compared to the stamping process used for hinge structures, can have higher yield strength and is less prone to deformation.

[0065] In some embodiments, refer to Figure 6The first connector 33 also includes an extension 333, which connects the third bushing portion 332 and the connecting portion 331. The thickness of the extension 333 is ( Figure 6 (represented by e1) is greater than the wall thickness of the third bushing portion 332. Figure 6 (represented by e2 in the text). The use of MIM (Medium Injection Molding) technology allows for thickening of the extension 333, i.e., locally thickening of the first connector 33, further enhancing the strength of the hinge structure and ensuring stable support. In some embodiments, the extension 333 is also located within the second opening 315.

[0066] In some embodiments, continue to refer to Figure 6 The extension 333 is connected to one end of the connecting portion 331 and a positioning step 3331 is formed therein. The positioning step 3331 has a first arc-shaped surface 3332 on the side facing the connecting portion 331. (Refer to...) Figure 2 The support member 40 extends from one end of the first connector 33 to form a protrusion 41. The protrusion 41 has a second arcuate surface 411 that matches the first arcuate surface 3332. The first connector 33 and the support member 40 are positioned and connected through the first arcuate surface 3332 and the second arcuate surface 411. This allows the support member 40 and the first connector 33 to be quickly positioned and connected.

[0067] In one specific embodiment of this application, the assembly process of the hinge structure and the annular base 20 is as follows: First, the third bushing portion 332 of the first connector 33 is placed between the first bushing portion 311 and the second bushing portion 312, so that the first shaft hole 3111, the third shaft hole 3321, and the second shaft hole 3121 are coaxially arranged and interconnected. Then, the second end 322 of the rotating shaft 32 is inserted through the first shaft hole 3111, through the third shaft hole 3321, and then into the second shaft hole 3121, so that the second end 322 is fixed in the second bushing portion 312, the first end 321 is fixed in the first bushing portion 311, and the third bushing portion 332 is sleeved on the middle of the rotating shaft 32 and rotatably connected to the rotating shaft 32. At this point, the hinge structure 30 is assembled. Next, the assembled hinge structure is placed in the mold of the ring base 20 and positioned by the positioning hole 3141 on the positioning part 314. Then, the ring base 20 is injection molded into the mold, so that the ring base 20 and the hinge structure 30 are fitted together, making the connection more stable and the resistance to deformation stronger.

[0068] In some embodiments, the annular base 20 is rotatably connected to the main body 10. Specifically, the annular base 20 can rotate about its axis perpendicular to the back plate 11 to achieve different support effects. For example... Figure 12 Vertical screen support effect and Figure 13 The horizontal screen support effect in the middle.

[0069] In some embodiments, the main body 10 is also provided with a base mounting groove 111 (see reference). Figure 2 The annular base 20 is disposed within the base mounting groove 111. The base mounting groove 111 can be an annular groove that matches the annular base 20 or a circular groove. This allows the annular base 20 to be mounted on the main body 10 without protruding from the surface of the main body 10, resulting in a smoother surface for the electronic device. The annular base 20 has a circumferentially extending protrusion 23 (see reference). Figure 3 The side wall of the base mounting groove 111 has a groove 1111 that matches the protruding structure 23 (see reference). Figure 2 The annular base 20 rotates relative to the main body 10 by rotating along the groove 1111 via the protruding structure 23. The protruding structure 23 can be disposed on the inner or outer side of the annular base 20. When disposed on the inner side, the groove 1111 is correspondingly disposed on the inner side wall of the base mounting groove 111. When disposed on the outer side, the groove 1111 is correspondingly disposed on the outer side wall of the base mounting groove 111. The arrangement of the protruding structure 23 and the groove 1111 enables stable rotation of the annular base 20. In some embodiments, there are multiple protruding structures 23, which are spaced apart. This ensures both the rotation of the annular base 20 and facilitates its installation. The protruding structure 23 can be integrally formed with the body of the annular base 20 or can be separately disposed, for example, it can be a metal retaining ring that snaps onto the annular base 20.

[0070] In some embodiments, a positioning component is also included, comprising a first positioning structure 51 and a second positioning structure 52, wherein the first positioning structure 51 is connected to the annular base 20 (see reference). Figure 7 and Figure 9 The second positioning structure 52 is set on the main body 10 (refer to...). Figure 2 The first positioning structure 51 can extend and retract relative to the annular base 20 when the annular base 20 rotates relative to the main body 10, thereby locking or unlocking with the second positioning structure 52. For example, an installation space can be provided on the side of the annular base 20 facing the main body 10, and the first positioning structure 51 can be installed within this space. The second positioning structure 52 can be provided on the side wall of the base mounting groove 111, with its position opposite to that of the groove 1111. Figure 2The groove 1111 shown is located on the outer sidewall of the base mounting groove 111, and the second positioning structure 52 is located on the inner sidewall of the base mounting groove 111. For example, mobile phones mainly have two landscape support directions and two portrait support directions, so four second positioning structures 52 can be set. Each time the annular base 20 is rotated 90°, the first positioning structure 51 retracts from the original second positioning structure 52 and engages and locks. When rotating to the position of the next second positioning structure 52, it extends into the next second positioning structure 52 and locks with it. By setting the first positioning structure 51 and the second positioning structure 52, the positioning structure 51 will not easily rotate after the annular base 20 is rotated to a specific position, thereby preventing the annular base 20 from rotating and causing instability during support.

[0071] In one specific embodiment, refer to Figure 10 and Figure 11 The first positioning structure 51 includes a spring 512 and a positioning member 511. One end of the spring 512 abuts against the annular base 20, and the other end abuts against the positioning member 511. (Refer to...) Figure 2 The second positioning structure 52 is a positioning groove, and the positioning member 511 can be engaged or disengaged from the positioning groove under the elastic action of the spring 512. In some embodiments, the first positioning structure 51 further includes a sleeve 513, which is sleeved on the spring 512. The sleeve 513 can reduce the impact of the spring 512 on the wireless charging function. The sleeve 513 can be made of metal or non-metal, and is not limited thereto. In some embodiments, two springs 512 are provided, and the two springs 512 are arranged side by side along the circumference of the annular base 20, which can make the extension and retraction of the positioning member 511 more balanced and prevent skewing during the rotation of the annular base 20. In some embodiments, the positioning member 511 also includes two positioning posts 514, and the two springs 512 are respectively sleeved on the two positioning posts 514. The setting of the positioning posts 514 can also prevent the spring from tilting. When the number of springs 512 is set to two, the number of sleeves 513 and positioning posts 514 is also set to two accordingly.

[0072] In some embodiments, refer to Figure 9 The annular base 20 is provided with a guide groove 24, and the positioning member 511 is provided with a guide block 5111 that matches the guide groove 24. The positioning member 511 can extend and retract by sliding along the guide groove 24 through the guide block 5111. The cooperation between the guide block 5111 and the guide groove 24 can further guide the extension and retraction of the positioning member 511 and prevent deflection.

[0073] The positioning member 511 includes a first mounting guide 5112 and a second mounting guide 5113 arranged circumferentially along the annular base 20. The first mounting guide 5112 is provided with a foolproof feature. For example, referring to… Figure 10and Figure 11 The two side wings of the positioning member 511 respectively form a first mounting guide portion 5112 and a second mounting guide portion 5113. Compared with the second mounting guide portion 5113, the first mounting guide portion 5112 has a stepped position as a foolproof part. This makes it easier to identify the installation direction when the first positioning structure 51 is installed on the annular base 20. In some embodiments, a first guide groove 25 matching the shape of the first mounting guide portion 5112 and a second guide groove 26 matching the shape of the second mounting guide portion 5113 can also be provided on the annular base 20. The first guide groove 25 and the second guide groove 26 are respectively located on opposite sides of the guide groove 24, making it impossible to install the positioning member 511 in reverse and facilitating correct installation.

[0074] In some embodiments, refer to Figure 15 It also includes a protective element 60, which covers the side of the annular base 20 facing away from the main body 10. The protective element 60 may be a Mylar sheet, providing abrasion protection to the surface of the annular base 20 when the support assembly is in its retracted state, preventing wear and tear from other objects placed on it. In some embodiments, refer to... Figure 16 The metal bearing 31 is also provided with a clearance groove 316. The bottom surface of the clearance groove 316 is flush with the surface of the annular base 20 facing away from the main body 10, and the protective member 60 also covers the clearance groove 316. The clearance groove 316 is located near the joint between the metal bearing 31 and the annular base 20, so that the protective member 60 can also protect the joint and prevent dust and other substances from entering.

[0075] In some embodiments, refer to Figure 7 For example, a magnet mounting slot 27 is provided on the side of the annular base 20 facing the main body 10, in which a magnet 70 can be installed. The magnet 70 can be an arc-shaped magnet or multiple magnet units arranged in an arc shape. The overall shape of the magnet 70 matches the wireless charging area, enhancing the stability when connected to the wireless charger.
