It should be understood that such terms can be used interchangeably where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0069] 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.

[0070] This utility model provides an electronic device accessory with a support frame, including a back panel 11 and a support assembly 20 disposed on the back panel 11. Specifically, referring to FIG1, the electronic device accessory with a support frame can be a protective shell with a support frame, including a shell 10 and a support assembly 20. In some embodiments, the back panel 11 is a component of the shell 10, which includes the back panel 11 and side frames 12. The back panel 11 and the side frames 12 together enclose a device housing cavity for accommodating the electronic device. When the shell 10 is fitted onto the electronic device, the back panel 11 is located on the back of the electronic device, and the shell 10 can protect the electronic device, while the support assembly 20 provides support. Alternatively, in some embodiments, the back panel 11 can be directly attached to the back of the electronic device using adhesive or other methods, with the support assembly 20 providing support for the electronic device.

[0071] The overall shape of electronic devices such as mobile phones and tablets is rectangular, and the housing 10 (or back panel 11) has mutually perpendicular length and width directions. The housing 10 has a top edge 15 and a bottom edge 16 opposite each other along the length direction, and two side edges 17 opposite each other in the width direction. For example, the housing 10 is also provided with a camera clearance hole communicating with the device receiving cavity, so that the camera of the electronic device can be exposed through the clearance hole.

[0072] Referring to Figure 2, in this electronic device accessory with a bracket, the bracket assembly 20 specifically includes a support member 21 and a base 22. The base 22 is connected to the back plate 11. The support member 21 has opposing first surfaces S1 and second surfaces S2. The support member 21 is rotatably connected to the base 22.

[0073] In some embodiments, the support member 21 can rotate relative to the base 22 to switch between a first position state and a second position state. As shown in FIG1, when the support member 21 is in the first position state, the support member 21 is stacked on the back plate 11, with the first surface S1 facing the back plate 11 and the second surface S2 facing away from the back plate 11. The support member 21 rotates 180° relative to the base 22 from the first position state to reach the second position state. In the second position state, as shown in FIG2, the second surface S2 of the support member 21 faces the back plate 11, and the first surface S1 faces away from the back plate 11. Specifically, in the second position state, the second surface S2 is in contact with the back plate 11.

[0074] The back panel 11 has a wireless charging corresponding area, which refers to the position corresponding to the wireless charging coil on the electronic device when the back panel 11 is connected to the electronic device (e.g., when the housing 10 is fitted onto the electronic device or when the back panel 11 is attached to the back of the electronic device). The first position state is, for example, the storage state of the support member 21, in which the support member 21 covers the wireless charging corresponding area of ​​the back panel 11, and in the second position state, the support member 21 covers the area outside the wireless charging corresponding area of ​​the back panel 11.

[0075] Specifically, the backplate 11 has an opposing outer surface S3 and an inner surface S4. When the backplate 11 is part of the housing 10, the outer surface S3 refers to the surface of the backplate 11 away from the device receiving cavity, and the inner surface S4 refers to the surface of the backplate 11 facing the device receiving cavity. When the backplate 11 is directly attached to the electronic device, the inner surface S4 refers to the surface of the backplate 11 used for connection with the electronic device, also known as the connection surface. The outer surface S3 refers to the surface of the backplate 11 opposite to the connection surface.

[0076] In one embodiment, the support member 21 is disposed on the outer surface S3 of the back plate 11, and in the first position state, the first surface S1 of the support member 21 is located above the outer surface S3 of the back plate 11, that is, in the first position state, the first surface S1 of the support member 21 is not lower than the outer surface S3 of the back plate 11. In a specific embodiment, in the first position state, the first surface S1 of the support member 21 is flush with the outer surface S3.

[0077] In one embodiment, in the second position state, the distance between the second surface S2 and the outer surface S3 is less than or equal to the distance between the first surface S1 and the outer surface S3 in the first position state. Since the distance between the outer surface S3 and the inner surface S4 is constant, it can also be said that the distance between the second surface S2 and the inner surface S4 in the second position state (referred to as the second distance) is less than or equal to the distance between the first surface S1 and the inner surface S4 in the first position state (referred to as the first distance).

[0078] In traditional charging cases, a ring-shaped bracket corresponding to the wireless charging coil is typically located on the back of the case. The metal material of the bracket or the magnets within it can affect charging efficiency. Furthermore, since the bracket is stored on the back panel, when retracted, the overall thickness of the bracket and back panel is approximately equal to the thickness of the back panel. However, when the bracket is rotated 180°, it protrudes from the back panel, increasing the overall thickness to the sum of the back panel's thickness and the bracket's thickness. This significant increase in thickness means that when the phone is placed on the wireless charging pad, the increased thickness widens the distance between the wireless charger's coil and the phone's coil, weakening the induction and impacting wireless charging efficiency.

[0079] In this embodiment, the support member 21 of the electronic device accessory with a bracket has, for example, a ring-shaped structure. When the support member 21 is in the second position and an external wireless charging device is connected to the electronic device accessory with a bracket, the distance between the surface of the wireless charging device and the back of the electronic device is a third distance. When the support member 21 is in the first position and an external wireless charging device is connected to the electronic device accessory with a bracket, the distance between the surface of the wireless charging device and the surface of the first electronic device is a fourth distance. The above settings ensure that the third distance is less than or equal to the fourth distance. Therefore, when the support member 21 is in the second position and connected to the wireless charging device, the distance between the wireless charging device and the electronic device remains unchanged or even reduced, and at this time, the support member 21 no longer covers the wireless charging area on the back plate 11. Therefore, the above settings can prevent the problem of weak or no wireless charging due to excessively large wireless charging time intervals, and can also reduce the impact of the metal material on the support member 21 on the wireless charging efficiency, thereby improving the efficiency of wireless charging.

[0080] For example, to make the back of the electronic device accessory with a stand flatter when the support member 21 is in the retracted state, a support member storage groove can be provided on the back plate 11, so that the support member 21 is completely located in the support member storage groove when retracted. In this case, the thickness of the back plate 11 itself will be relatively thick. For example, the overall thickness of the back plate 11 is 3 mm, and the overall thickness of the support member 21 is 1.8 mm. If a wireless charging device is connected when the support member 21 is in the first position, the distance between the charging device and the inner surface S4 of the back plate 11 (hereinafter referred to as the sensing distance) is 3 mm. Although the sensing distance is small, it has a significant impact on the charging efficiency if the support member 21 is made of metal or has a magnet on it. Therefore, the above embodiment makes the support member 21 have a second position. When the support member 21 is in the second position, the wireless charging device is connected. This can reduce the impact of the material of the support member 21 on the charging efficiency. However, the sensing distance at this time is the sum of the overall thickness of the back plate 11 and the thickness of the support member 21, which is 4.8 mm. The larger sensing distance at this time will affect the sensing effect of wireless charging. Therefore, according to the above embodiment, in the first position state, the first surface S1 of the support member 21 is located above the outer surface S3 of the back plate 11, that is, the support member 21 is completely outside the back plate 11. At this time, no support member storage slot for accommodating the support member 21 is opened on the back plate 11, and the overall thickness of the back plate 11 can be designed by subtracting the thickness of the support member 21. For example, if the overall thickness of the back plate 11 is 1.2 mm and the overall thickness of the support member 21 is 1.8 mm, then if a wireless charging device is connected in the first position state, the sensing distance is 3 mm. In the second position state, the sensing distance is still 3 mm. When charging is performed with the support member 21 in the second position state, the sensing distance does not increase, and the influence of the material of the support member 21 on the charging efficiency can be reduced, thus improving the charging efficiency.

[0081] The base 22 includes, for example, a bushing portion 221, and the support assembly 20 includes a rotating shaft 23. The rotating shaft 23 passes through the bushing portion 221 to allow the support member 21 to rotate relative to the bushing portion 221, thereby switching from a first position state to a second position state. By protruding the bushing portion 221 onto the outer surface S3 of the back plate 11, the second surface S2 can contact the outer surface S3 of the back plate 11 in the second position state, which means that the support member 21 can be rotated 180°.

[0082] In some embodiments, referring to FIG2, the electronic device accessory with a bracket further includes a magnetic assemblies 30, which include, for example, a first magnetic unit 31. The first magnetic unit 31 is connected to the support member 21. In some embodiments, the support member 21 includes a support body 211, on which a first mounting groove 2111 is provided (see FIG18 and FIG20), and the first magnetic unit 31 is disposed in the first mounting groove 2111. The support member 21 may also include a second cover member 212, which covers the first mounting groove 2111 to cover the first magnetic unit 31, ensuring aesthetics and protecting the first magnetic unit 31. The first magnetic unit 31 includes, for example, multiple magnets, which are arranged in an arc or ring shape to correspond to the magnetic area on the electronic device. When the support member 21 is in a first position, the first magnetic unit 31 can be used to attract other external accessories (such as vehicle mounts) to the support member 21, thereby achieving a magnetic connection between the electronic device accessory with a bracket and external devices.

[0083] In some embodiments, the magnetic assembly 30 further includes a second magnetic unit 32, which is disposed at the end of the support member 21 away from the bushing portion 221. The second magnetic unit 32 can be magnetically connected to a magnet at the wireless charging coil on the electronic device, so that the support member 21 can remain in a first position and not easily open when the support function and wireless charging are not needed. Alternatively, in some embodiments, the base 22 further includes a base body 222 connected to the back plate 11, and a magnetic member can be disposed at a corresponding position on the base body 222 to magnetically attract the second magnetic unit 32, thereby maintaining the support member 21 in the first position.

[0084] In some embodiments, the magnetic assembly 30 further includes a third magnetic unit 33, which is disposed on the back plate 11 and located on one side of the bracket assembly 20, specifically at one end of the bracket assembly 20 along the length direction of the housing 10 near the bottom edge 16 of the housing 10. The third magnetic unit 33 is used for positioning when the electronic device is magnetically attached, and is typically elongated elliptical in shape, with its length direction aligned with the length direction of the housing 10 and centered in the width direction of the housing 10. The third magnetic unit 33 can also be designed as a sensor; when a wireless charger or wireless power bank is magnetically attached to the phone case, the sensor is triggered to activate the wireless fast charging mode.

[0085] In some embodiments, the base 22 is rotatably connected to the back plate 11. Specifically, the base 22 can rotate relative to the back plate 11 about an axis perpendicular to the back plate 11. This allows for switching between landscape and portrait screen support.

[0086] Specifically, the base 22 includes a base body 222 (see Figure 2).

[0087] In some embodiments, referring to Figures 17 and 18, the base body 222 may be an arc-shaped structure, disposed on the side of the back plate 11 facing the support member 21. The base body 222 can be connected to the back plate 11 by riveting. Setting the base body 222 as an arc-shaped structure can reduce the area of ​​the base body 222, further reducing the impact of the base body 222 on the wireless charging efficiency. Referring to Figures 19 and 20, the base body 222 and the support member 21 can be disposed on opposite sides of the back plate 11. By setting the base mounting portion 111 on the back plate 11 as a through hole, the bushing portion 221 can pass through the through hole to the outer surface S3 side of the back plate 11, so that the support member 21 can be rotatably connected to the bushing portion 221 via the rotating shaft 23.

[0088] In some embodiments, the base body 222 has an annular structure. Referring to Figures 3 and 4, a base mounting portion 111 is provided on the back plate 11, and the base mounting portion 111 is an annular groove that matches the shape of the base body 222. The base body 222 is disposed on the base mounting portion 111.

[0089] In one embodiment, the electronic device accessory with bracket further includes a rotatable connection assembly 40. In one embodiment, referring to Figures 5 and 6, the rotatable connection assembly 40 includes a rotatable connector 41 disposed around the base body 222 and connected to both the base body 222 and the back plate 11, and the rotatable connector 41 is rotatably connected to at least one of the base body 222 and the back plate 11.

[0090] In some embodiments, a first slot 1111 is provided on the base mounting portion 111, and a second slot 223 is provided on the base body 222. A rotating connector 41 is disposed around the base body 222 and is respectively engaged in the first slot 1111 and the second slot 223, and can rotate relative to the first slot 1111 or the second slot 223. This allows the base body 222 to rotate relative to the back plate 11 and prevents it from easily falling off. The rotating connector 41 is, for example, an annular structure with an opening as shown in FIG. 5, which allows the rotating connector 41 to deform for easy assembly. In some embodiments, a gap is formed between the rotating connector 41 and the bottom of at least one of the first slot 1111 and the second slot 223 to provide deformation space for the rotating connector 41. In some embodiments, referring to FIG. 6, the radial cross-section of the rotating connector 41 is, for example, a "Z" shaped structure. More specifically, the distance between the first slot 1111 and the inner surface S4 of the back plate 11 is smaller than the distance between the second slot 223 and the inner surface S4 of the back plate 11. The distance between the side of the rotating connector 41 closest to the first slot 1111 and the inner surface S4 is less than the distance between the side of the rotating connector 41 closest to the second slot 223 and the inner surface S4. Therefore, the thickness of the base body 222 can be set to be thicker than the back plate 11, facilitating a stable connection without affecting wireless charging efficiency.

[0091] In other embodiments, referring to Figures 10, 11, and 13, the rotating connector 41 can be connected to the side of the base body 222 facing the back plate 11, for example, by welding or bonding. The back plate 11 has a first slot 1111, and the edge of the rotating connector 41 protrudes from the edge of the base body 222 and is engaged in the first slot 1111.

[0092] In some embodiments, referring to Figures 4 to 6, the rotating connection assembly 40 further includes a damping element 42. The damping element 42 is disposed on the side of the base body 222 facing the back plate 11. Referring to Figure 4, more specifically, a second mounting groove 224 is provided on the side of the base body 222 facing the back plate 11, and the damping element 42 is disposed within the second mounting groove 224. The damping element 42 may be made of silicone material, for example, which can increase the friction between the base body 222 and the back plate 11, so that the base body 222 can maintain the angle after rotating at a certain angle and will not change the angle due to slight shaking or other reasons. In some embodiments, the side of the damping element 42 facing the back plate 11 also protrudes from the surface of the base body 222 facing the back plate 11.

[0093] In some embodiments, referring to Figures 7, 8, or 13, a rotation limiting component 50 is further provided between the base 22 and the back plate 11. The rotation limiting component 50 includes a second limiting portion 52 connected to the back plate 11 and a first limiting portion 51 connected to the base 22. In some embodiments, there are multiple first limiting portions 51, and the second limiting portion 52 can be selectively connected to one of the multiple first limiting portions 51 when the base 22 rotates relative to the back plate 11. This ensures that when the base 22 is not rotated by an external force, the second limiting portion 52 is connected to one of the multiple first limiting portions 51, and the base 22 remains at that angle. When an external force is applied to rotate the base 22, the second limiting portion 52 can disengage from the original first limiting portion 51 and connect to the next first limiting portion 51. When the external force is stopped, the base 22 can maintain the relative position of the support member 21 and the back plate 11 through the cooperation of the first limiting portion 51 and the second limiting portion 52, ensuring a stable support angle.

[0094] Specifically, one of the first limiting portion 51 and the second limiting portion 52 includes a protrusion, and the other of the first limiting portion 51 and the second limiting portion 52 includes a groove. The shape of the protrusion matches the shape of the groove; for example, the groove is an arc-shaped groove, and the protrusion is a spherical or hemispherical protrusion.

[0095] In some embodiments, referring to FIG9, the second limiting portion 52 includes a fixing portion 521, a deformable portion 522, and a second snap-fit ​​portion 523 that cooperates with the first limiting portion 51. The fixing portion 521 is fixedly connected to the back plate 11. For example, the fixing portion 521 is provided with a slot 5211, which can be a through slot. By providing a plug-in portion 112 on the back plate 11 that matches the slot 5211, the fixing portion 521 and the back plate 11 can be fixedly connected by plugging the plug-in portion 112 into the slot 5211. Referring to FIGS. 10 and 12, in some embodiments, the fixing portion 521 is located on the side of the back plate 11 away from the bracket assembly 20. The width of the slot 5211 gradually increases in the direction away from the back plate 11, and the plug-in portion 112 on the back plate 11 gradually increases in the direction closer to the fixing portion 521, making the connection between the fixing portion 521 and the back plate 11 more stable. In some embodiments, the electronic device accessory with a bracket further includes a first cover 13, which is disposed on the side of the fixing portion 521 away from the back plate 11, i.e., the fixing portion 521 is sandwiched between the back plate 11 and the first cover 13. A deformable portion 522 is disposed at one end of the fixing portion 521 near the base 22, and a second snap-fit ​​portion 523 is disposed on the surface of the deformable portion 522 facing the base 22. A displacement space is formed on the side of the deformable portion 522 away from the base 22.

[0096] Referring to FIG12, in some embodiments, the first limiting part 51 is disposed on the side of the base 22 facing the back plate 11. Referring to the orientation shown in FIG12, when the base 22 is rotated, the second limiting part 52 deforms and moves downward through the deformation part 522, so that the second engaging part 523 disengages from the original first limiting part 51. When the next first limiting part 51 rotates above the second engaging part 523, the deformation part 522 restores its deformation, so that the second engaging part 523 engages with the first limiting part 51.

[0097] In some embodiments, referring to Figures 13 to 15, the first limiting part 51 is provided, for example, on the side of the base body 222. Referring to the orientation shown in Figure 15, when the base 22 is rotated, the second limiting part 52 deforms and moves outward through the deformation part 522, causing the second engaging part 523 to disengage from the original first limiting part 51. When the next first limiting part 51 rotates above the second engaging part 523, the deformation part 522 returns to its original deformation, causing the second engaging part 523 to engage with the first limiting part 51.

[0098] The above settings not only enable multi-angle positioning of the bracket assembly 20, but also produce a "clicking" sound effect when rotating.

[0099] In some embodiments, in an electronic device accessory with a bracket, referring to Figures 16 and 17, the pivot 23 (axis) is inclined to the length direction of the housing 10 and to the width direction of the housing 10. The line connecting the pivot 23 and the center of the support member 21 in the first position state is inclined to the length direction of the housing 10 and to the width direction of the housing 10. In other words, the distances between the pivot 23 and the two side edges 17 of the housing 10 in the width direction are not equal, and the distance from the pivot 23 to the bottom edge 16 of the housing 10 is greater than the minimum distance between the bracket assembly 20 (support member 21 in the first position state) and the bottom edge 16 of the housing 10. Referring to the orientation shown in Figure 16, the pivot 23 is located on the lower right side of the entire bracket assembly 20 (support member 21 in the first position state). In some embodiments, the pivot 23 may also be located on the lower left side of the entire bracket assembly 20 (support member 21 in the first position state). Alternatively, the distances between the pivot 23 and the two side edges 17 of the housing 10 in the width direction are not equal, and the distance from the pivot 23 to the top edge 15 of the housing 10 is greater than the minimum distance between the support assembly 20 (support member 21 in the first position state) and the top edge 15 of the housing 10. Referring to the orientation shown in FIG16, the pivot 23 can also be located on the upper left or upper right side of the entire support assembly 20 (support member 21 in the first position state).

[0100] In traditional bracket protective shells, the pivot 23 is arranged parallel to the width direction of the protective shell. In this embodiment, the pivot 23 is arranged at an angle. Referring to Figures 21 and 22, when the support member 21 is rotated 180 degrees to the second position, the orthographic projection of the support member 21 on the back plate 11 intersects at least partially with the orthographic projection of the third magnetic unit 33 on the back plate 11. Thus, when the support member 21 is rotated 180 degrees, it can be magnetically connected to the support member 21 (either the first magnetic unit 31 or the metal material of the support member 21) through the third magnetic unit 33, preventing the support member 21 from shaking.

[0101] In a specific embodiment, the angle (acute angle, see α in Figure 16) between the line connecting the center of the rotating shaft 23 and the support member 21 and the length direction of the housing 10 is in the range of 0~45°, and more specifically, the range of α is 10~30°. The angle (acute angle, 90°-α) between the rotating shaft 23 and the length direction of the housing 10 is in the range of 0~45°.

[0102] In this embodiment, referring to FIG22, in the second position state, one end of the support member 21 near the bottom edge 16 of the housing 10 is located between the bottom edge 16 and the top edge 15 of the housing 10. That is, in the second position state, the edge of the support member 21 does not extend beyond the bottom edge 16 of the housing 10, so that the support member 21 will not interfere with the charging dock, and is suitable for charging with the charging dock.

[0103] In some embodiments, as shown in FIG17, a barrier 14 is provided on the surface of the back panel 11. In the first position state, the barrier 14 surrounds the support member 21, so that the gap between the support member 21 and the back panel 11 is blocked by the barrier 14, preventing headphone wires and other debris from entering the gap between the support member 21 and the back panel 11 and causing entanglement during storage.

[0104] In one embodiment, the base 22 is rotatably connected to the back plate 11. Specifically, the base 22 can rotate about an axis perpendicular to the back plate 11. A support member 21 is disposed on the outer surface S3 of the back plate 11, and the support member 21 can switch between a first position state and a third position state as the base 22 rotates relative to the back plate 11. In both the first and third position states, the support member 21 is stacked on the back plate 11, with the first surface S1 facing the back plate 11 and the second surface S2 facing away from the back plate 11. Starting from the first position state, the support member 21 remains relatively stationary with respect to the base 22. After the base 22 rotates 180° about an axis perpendicular to the back plate 11, the support member 21 switches to the third position state. In the first position state, the support member 21 covers the wireless charging corresponding area of ​​the back plate 11, and in the second position state, the support member 21 covers the area outside the wireless charging corresponding area of ​​the back plate 11. The wireless charging area is located, for example, in the middle of the back panel 11. In other words, in the first position, the support member 21 is located on the side of the base 22 near the top edge 15 (see Figure 23), and in the third position, the support member 21 is located on the side of the base 22 near the bottom edge 16 (see Figure 24).

[0105] With the above settings, not only can the support adjustment be achieved at multiple angles such as horizontal or vertical screen support by rotating the base 22 relative to the back plate 11, but the support member 21 can also be made not to cover the corresponding area of ​​wireless charging by rotating the base 22 relative to the back plate 11. During the rotation of the base 22 relative to the back plate 11, the distance between the second surface S2 of the support member 21 and the inner surface S4 of the back plate 11 does not change. Therefore, the above settings can prevent the problem of weak or no wireless charging due to excessive time interval, and can also reduce the impact of the metal material on the support member 21 on the wireless charging efficiency, thereby improving the efficiency of wireless charging.

[0106] In this embodiment, a rotation limiting assembly 50 is further provided between the base 22 and the back plate 11. The rotation limiting assembly 50 includes a first limiting portion 51 connected to the base 22 and a second limiting portion 52 connected to the back plate 11. When the base 22 rotates relative to the back plate 11, the first limiting portion 51 rotates with the base 22, while the second limiting portion 52 remains relatively stationary with the back plate 11. In some embodiments, there are multiple second limiting portions 52. The first limiting portion 51 can selectively be limited and connected to one of the multiple second limiting portions 52 as the base 22 rotates relative to the back plate 11. This ensures that when no external force causes the base 22 to rotate, the first limiting portion 51 is limited and connected to one of the multiple second limiting portions 52, and the base 22 remains at that angle. When an external force is applied to rotate the base 22, the first limiting portion 51 can disengage from the original second limiting portion 52 and be limited and connected to the next second limiting portion 52. When the external force is stopped, the base 22 can maintain the relative position of the support member 21 and the back plate 11 by the cooperation of the first limiting part 51 and the second limiting part 52, thus ensuring a stable support angle.

[0107] In some embodiments, referring to FIG25, the electronic device with a bracket further includes a first base connector 61. The first base connector 61 is connected to the back plate 11, and the base 22 is rotatably connected to the first base connector 61. Referring to FIG25, the back plate 11 is provided with a through hole as a base mounting portion 111, for example. Referring to FIGS. 26, 27 and 28, the first base connector 61 includes a side wall 611, a flange 612 and a third snap-fit ​​portion 613. The side wall 611 is disposed inside the base mounting portion 111 and covers the inner wall of the base mounting portion 111. The flange 612 is connected to one end of the side wall 611 near the outer surface S3 of the back plate 11 and extends toward the side of the side wall 611 away from the center of the base mounting portion 111 onto the outer surface S3. The third snap-fit ​​portion 613 is connected to the other end of the side wall 611. The connection between the first base connector 61 and the back plate 11 can be realized through the flange 612, the side wall 611 and the third snap-fit ​​portion 613. In some embodiments, referring to FIG25, a third slot 1112 corresponding to the third snap-fit ​​portion 613 is provided on the base mounting portion 111. The third snap-fit ​​portion 613 is snapped into the third slot 1112, so that the first base connector 61 and the back plate 11 do not rotate. Referring to FIGS. 26, 27 and 28, the base 22 specifically includes a base body 222 and an intermediate connector 225. The base body 222 and the intermediate connector 225 are fixedly connected together, for example, by riveting. The base body 222 has a plurality of connecting portions 2222 protruding on the side facing the intermediate connector 225. Correspondingly, the intermediate connector 225 has a plurality of connecting holes 2251. The connecting portions 2222 are riveted and fixed in the connecting holes 2251, thereby fixing the base body 222 and the intermediate connector 225 together. Of course, in other embodiments, the connecting portion 2222 and the connecting hole 2251 can also be one. After the base body 222 and the intermediate connector 225 are fixed together, their edges are spaced apart to form a slot 220. The base mounting portion 111 on the back plate 11 is a through hole, and the sidewall of the through hole (i.e., a part of the back plate 11) is engaged in the slot 220 so that the base 22 is installed in the base mounting portion 111 and can rotate within the base mounting portion 111. The intermediate connector 225 can be provided on the side of the third engaging portion 613 facing away from the flange 612. The intermediate connector 225 can also limit the first base connector 61. In some embodiments, a first cover 13 is also provided on the side of the intermediate connector 225 away from the base body 222. The first cover 13 can cover the intermediate connector 225 to ensure aesthetics. The first cover 13 is, for example, a sheet made of one or more of the following materials: PC (polycarbonate), silicone, TPU (thermoplastic polyurethane elastomer), etc.

[0108] In some embodiments, the width of the flange 612 extending over the outer surface S3 is designed to be non-uniform. For example, referring to the orientation shown in FIG27, the width on the left side of the flange 612 is greater than the width on the right side, which can make the friction between the two sides and the outer surface S3 different, and can also prevent the first base connector 61 from rotating relative to the back plate 11.

[0109] Referring to Figures 28 and 29, in some embodiments, the second limiting portion 52 is formed on the first base connector 61. In the specific embodiment shown in Figures 28 and 29, the second limiting portion 52 is a groove formed on the side wall 611 of the first base connector 61. Correspondingly, a limiting groove 1113 can be provided on the inner wall of the base mounting portion 111. The area of ​​the side wall 611 covering the limiting groove 1113 is recessed to form the second limiting portion 52. That is, the second limiting portion 52 is stacked together with the limiting groove 1113 and engages with the limiting groove 1113, so that the first base connector 61 can also be limited by the limiting groove 1113 to prevent rotation relative to the back plate 11. Of course, in other embodiments, the first base connector 61 may not be provided. In this case, the limiting groove 1113 provided on the inner wall of the base mounting part 111 can be formed as the second limiting part 52, which is used to cooperate with the first limiting part 51 to limit the base 22. The side wall of the through hole on the back plate 11a (i.e., a part of the back plate 11a) is directly stuck in the slot 220, thereby realizing the rotatable connection between the base 22 and the back plate 11a. In other embodiments, the first base connector 61 may be an annular structure, and a groove is provided on the inner side of the annular structure to form the second limiting part 52. The base mounting part 111 may be a through hole structure, and a groove can be provided on the inner wall of the base mounting part 111 accordingly. A part of the side wall of the outer side of the first base connector 61 is embedded in the groove to install the first base connector 61 in the base mounting part 111. After the base 22 is installed in the base mounting part 111, the first limiting part 51 and the second limiting part 52 cooperate to achieve the limiting.

[0110] Referring to FIGS. 27 to 29, the rotation limiting component 50 further includes an elastic member 53. The first limiting portion 51 is connected to one end of the elastic member 53 and can extend out of or retract into the base body 222 under the elastic action of the elastic member 53 to be in limiting connection with or release the limiting connection with the second limiting portion 52. The elastic member 53 is, for example, a spring. The specific working principle is as follows. First, for example, the base 22 is in a stationary state relative to the back plate 11. Under the elastic force of the elastic member 53, the first limiting portion 51 abuts against the second limiting portion 52 to achieve limiting connection. At this time, without external force, the base 22 can remain stationary relative to the back plate 11. When an external force is applied to rotate the base 22, the side wall of the second limiting portion 52 presses the first limiting portion 51, the elastic member 53 is compressed, and the first limiting portion 51 can be separated from the second limiting portion 52. When rotated to the next position where the second limiting portion 52 faces the first limiting portion 51, the elastic member 53 pops out the first limiting portion 51 to abut against the second limiting portion 52. When the force application stops, the base 22 can be held in this position.

[0111] In some embodiments, referring to FIGS. 27 to 2, on one side of the base body 222 facing the back plate 11, an installation cavity 2221 is further formed. The elastic member 53 and the first limiting portion 51 are arranged in the installation cavity 2221 to rotate with the base body 222. The installation cavity 2221 is an installation groove provided on the base body 222. The installation groove is integrally in the shape of a Chinese character 'zhong' or a 'T'. The first limiting portion 51 includes a U-shaped main body, and two end portions of the U-shaped main body at the opening face opposite directions and are bent and extended away from the inside of the U-shaped main body to form two limiting ends. Among them, the U-shaped main body of the first limiting portion 51 is located in the vertical part of the 'zhong'-shaped or 'T'-shaped installation groove, and the two limiting ends are respectively located in the horizontal part of the 'zhong'-shaped or 'T'-shaped installation groove and are respectively abutted against the side walls of the installation groove to limit the size of the part of the bottom of the U-shaped main body protruding out of the installation groove. At the same time, the two limiting ends of the first limiting portion 51 can move in the horizontal part of the installation groove to ensure that the first limiting portion 51 can move in the direction of the vertical part of the installation groove. The U-shaped main body of the first limiting portion 51 can at least partially extend out of or retract into the installation groove under the action of the elastic member 53. When the U-shaped main body extends out of the installation groove under the action of the elastic member 53, it can abut against the second limiting portion 52.

[0112] The intermediate connector 225 is also provided with a strip-shaped first clearance hole 2252, which is positioned corresponding to the pivot 23 of the support assembly 20 to prevent the intermediate connector 225 from interfering with the support assembly 20 when it is opened. The intermediate connector 225 is also provided with a second clearance hole 2253 corresponding to the position of the elastic member 53, so that when the intermediate connector 225 is connected to the base body 222, the elastic member 53 is at least partially exposed in the second clearance hole 2253, allowing space for the elastic member 53 and thus reducing the overall thickness of the base 22. The extending direction of the first clearance hole 2252 is perpendicular to the extending direction of the second clearance hole 2253.

[0113] The support member 21 also includes a hinge 213. The support body 211 has a recessed hinge fixing part 2112, and the hinge fixing part 2112 has a plurality of connecting posts 2113 protruding from it. The hinge 213 is provided with a plurality of connecting through holes 2131 and a bushing part 221. The middle part of the rotating shaft 23 is fitted inside the bushing part 221, and both ends of the rotating shaft 23 extend out of the bushing part 221 and are inserted into the two shaft holes 2223 of the base body 222. The connecting through holes 2131 of the hinge 213 are fitted onto the connecting posts 2113, so as to realize the fixed connection between the hinge 213 and the hinge fixing part 2112, so that the support member 21 can be rotatedly connected to the base 22 through the hinge 213 and the rotating shaft 23. Specifically, in this embodiment, the two sides of the rotating shaft are provided with cutting planes, the middle part of the rotating shaft 23 is damped and rotatably connected to the bushing part (that is, the rotating shaft 23 can be damped and rotated within the bushing part), and the two ends of the rotating shaft 23 are fixedly connected to the two shaft holes 2223 of the base body 222, thereby realizing the rotatable connection between the support member 21 and the base body. Moreover, through the damping cooperation between the middle part of the rotating shaft 23 and the bushing part, the support member 21 can be opened to any angle for positioning. In other embodiments, the middle part of the rotating shaft 23 can be fixedly connected to the bushing part, and the two ends of the rotating shaft 23 can be damped and rotatably connected to the two shaft holes 2223 of the base body 222 to realize the rotatable connection between the support member 21 and the base body 222.

[0114] In some embodiments, referring to FIG25, a button 121 is also provided on the side frame 12. The button 121 is used for users to perform operations such as pressing and touching, so as to control the corresponding buttons on the mobile phone or other electronic devices to realize the corresponding functions of the mobile phone, such as powering on / off, volume adjustment, taking pictures, etc. The button 121 and the side frame 12 can be integrally molded, that is, the button 121 and the side frame 12 are integrally injection molded by processes such as injection molding. In order to ensure that the force applied to the button 121 can be transmitted to the button on the mobile phone when the button 121 is pressed, the side frame 12 and the button 121 can be made of soft materials such as TPU or silicone. When pressed, the button 121 or a part of the side frame 12 around the button 121 can deform, so that the button 121 abuts against the button on the mobile phone, and transmits the pressing force to the button on the mobile phone to complete the transmission of operation commands. Of course, the materials of the button 121 and the side frame 12 are not limited. Since the button 121 is usually elongated, it is only necessary to ensure that one or both ends of the button 121 in the length direction are connected to the side frame 12 during injection molding, while the two sides in the width direction are not connected to the side frame 12 and are spaced apart. At this time, the part between the two ends of the button 121 in the length direction is in a suspended state. When the button 121 is pressed, the button 121 can easily deform and come into contact with the button on the mobile phone to transfer the pressing force to the button on the mobile phone. In other embodiments, the button 121 and the side frame 12 may not be integrally molded, but rather mounted on, as shown in Figure 39. Specifically, during the injection molding of the side frame 12, holes 123 for mounting buttons 121 can be provided at corresponding positions. Simultaneously, a recessed groove 1211 is formed around the side edge of the button 121. During installation, the button 121 is placed inside the hole 123, with the edge of the hole 123 extending into the groove 1211 to hold the button 121 in place, thus securing the button 121 to the side frame 12. Furthermore, to ensure that pressing the button 121 allows it to abut against the phone's buttons and transmit force, the button 121 can also move slightly along the thickness direction of the side frame 12 within the hole 123. Further, for easier installation, a ring of retaining protrusions 124 can be provided on the side wall of the hole 123. The thickness of the retaining protrusions 124 is thinner than the side wall of the hole 123, making it easier for them to extend into the groove 1211, thus connecting the button 121 to the side frame 12.

[0115] Further referring to Figure 25, in addition to providing button 121 for users to press, touch, and operate, and to control corresponding buttons on mobile phones and other electronic devices through button 121, button clearance holes 122 can also be provided to expose the phone's buttons for easier user operation. For example, when the phone's buttons are touch-sensitive, pressing button 121 may cause incompatibility issues. Therefore, button clearance holes 122 can be provided to directly expose the touch-sensitive buttons, making it easier for users to operate them by touch. The button clearance hole 122 is a through hole penetrating the side frame 12, and its size can be the same as or slightly larger than the buttons on the phone to ensure that the buttons on the phone are fully exposed. At the same time, a sloped ramp with an incline can be provided on the outer surface of the side frame 12 and around the button clearance hole 122. When the user operates, the ramp can play a certain guiding role, making it easier for the user to operate, and the ramp also makes it easier for the user to touch the surface of button 121 to operate. In other embodiments, when the phone's buttons are mechanical buttons, button clearance holes 122 can be provided to expose them for easy pressing by the user. Similarly, when the phone's buttons are touch buttons, button 121 can be provided to cooperate with them. In this case, the structure of button 121 needs to be adjusted. For example, a signal transmission component can be provided to conduct electricity between the inner and outer surfaces of button 121. For example, a conductive component can be provided. When the user touches button 121, the conductive component can transmit the microcurrent signal from the user's finger to the touch button of the phone, thereby realizing the operation of the touch button of the phone. Since the side of the phone usually has multiple or different types of buttons, buttons 121 and / or button clearance holes 122 can be flexibly provided on the side frame 12 of the protective case to cooperate with the buttons on the side of the phone to achieve the best operation and control experience. Similarly, in the embodiment shown in Figure 39, buttons 121 and / or button clearance holes 122 can also be provided as needed to meet the requirements, which will not be elaborated here.

[0116] In some embodiments, referring to FIG30, the electronic device accessory with bracket further includes a second base connector 62. The second base connector 62 is disposed within the base mounting portion 111 and fixedly connected to the back plate 11. The second base connector 62 is provided with a receiving groove, and the first base connector 61 is connected to the second base connector 62. The depth of the receiving groove in the second base connector 62 is greater than the depth of the through hole in the base mounting portion 111 (i.e., the thickness of the back plate 11), which provides sufficient space for the installation of the rotating connector 41 and the second limiting portion 52. Referring to FIGS. 30, 31, 32 and 33, the base body 222 is provided with a second slot 223, and the second base connector 62 is provided with a first slot 1111. The rotating connector 41 is respectively engaged in the first slot 1111 and the second slot 223. The first base connector 61 has a ring-shaped structure and is connected to the second base connector 62. The first base connector 61 is snapped into the bottom of the groove of the second base connector 62, and the second limiting part 52 is formed on the inner edge of the first base connector 61.

[0117] Specifically, the first base connector 61 is an annular thin sheet, and the first limiting part 51 includes a limiting body 511 and a first snap-fit ​​part 512. The first snap-fit ​​part 512 is configured as a sheet-like protrusion corresponding to the second limiting part 52, for limiting connection with the second limiting part 52. In some embodiments, the first snap-fit ​​part 512 is disposed at the end of the limiting body 511 away from the base body 222. The sheet-like structure of the first base connector 61 and the first snap-fit ​​part 512 can reduce the thickness occupied.

[0118] Referring to Figure 32, in this embodiment, the rotation limiting assembly 50 further includes a guide member 54. Specifically, the guide member 54 can be a columnar structure. The elastic member 53 and the limiting body 511 (first limiting part 51) are sleeved on the guide member 54, so that the elastic member 53 can extend and retract along the guide member 54, and drive the limiting body 511 to slide along the guide member 54, which can guide the movement of the limiting body 511 (first limiting part 51).

[0119] In one embodiment, referring to Figures 34-40, and essentially the same as the embodiments shown in Figures 23-29, the electronic device accessory can be, for example, a protective case for protecting electronic devices such as mobile phones and tablets. The electronic device accessory includes a back panel 11 and a side frame 12. The bracket assembly 20 includes a support member 21 and a base 22. The outer surface of the back panel 11 is provided with a storage groove 70 and a base mounting portion 111. The base mounting portion 111 can be, for example, a through hole penetrating the back panel 11 or a groove recessed on the outer surface of the back panel 11. The outer surface of the back panel 11 refers to the surface of the back panel 11 away from the electronic device when the protective case is fitted onto it. The support member 21 is rotatably connected to the base 22. Through the rotation between the two, the support member 21 can be opened relative to the back panel 11 for support, as shown in Figure 35. The support member 21 can be stored in the storage groove 70, as shown in Figure 33. The base 22 is mounted on the base mounting part 111, and the base 22 can rotate horizontally relative to the back panel 11. When the base 22 rotates horizontally relative to the back panel 11, it can drive the support member 21 to rotate with the base 22, thereby changing the opening direction of the support member 21. This allows the support member 21 to open from the corresponding direction whether the electronic device is used in landscape or portrait mode, providing stable support. Furthermore, the storage slot 70 is connected to the base mounting part 111 to ensure that the support member 21 can be completely stored in the storage slot 70. After the support member 21 is stored in the storage slot 70, the support member 21 is basically flush with the surface of the back panel 11, making it more comfortable for the user to hold the protective case, and the user can hardly feel the presence of the support member 21.

[0120] Referring further to Figure 40, when the base mounting part 111 is a through hole penetrating the back plate 11, a first cover 13 is also provided on the inner surface of the back plate 11. The first cover 13 is, for example, a sheet made of one or more of the following materials: PC (polycarbonate), silicone, TPU (thermoplastic polyurethane elastomer), etc. The first cover 13 is used to cover the opening of the through hole, which on the one hand makes the inner surface of the back plate 11 flatter and more aesthetically pleasing, and on the other hand can cover the base 22, which can effectively prevent the base 22 from rubbing against the surface of the electronic device when it rotates relative to the back plate 11. The first cover 13 is attached to the inner surface of the back plate 11 with adhesive. For example, the back plate 11 around the opening of the through hole is recessed to form a groove, and the first cover 13 is attached to the groove to ensure that the first cover 13 is flat with the inner surface of the back plate 11, and at the same time, it can also prevent the first cover 13 from moving left and right.

[0121] Referring further to Figures 41, 42, 45, and 46, the support member 21 includes a support body 211, a second cover 212, a hinge 213, and an insulating member 214. The support body 211 is annular and can be made of metals such as aluminum, zinc, and iron, or other alloys such as aluminum alloys and zinc alloys, to ensure the strength of the support body 211 during use. The support body 211 is also provided with a first mounting groove 2111, which is arc-shaped and extends circumferentially along the support body 211. In the embodiment shown in the figures, there are two first mounting grooves 2111, which are symmetrically arranged on the support body 211. A magnetic suction assembly 30 is disposed in the first mounting groove 2111, wherein the magnetic suction assembly 30 is divided into two arc-shaped parts, each part being formed by a plurality of first magnetic suction units 31 arranged together, and each arc-shaped part is correspondingly installed in one first mounting groove 2111. The magnetic component 30 enables the support member 21 to have magnetic attraction capabilities. Users can use the magnetic attraction of the support member 21 to magnetically attach electronic devices to surfaces with magnetic surfaces, such as refrigerators or stands. For example, a user can magnetically attach their phone to a refrigerator, providing a good shooting position without a tripod for taking photos or recording videos. In other usage scenarios, to prevent the phone from shifting and affecting charging, users can choose a wireless charger with magnetic attraction. The wireless charger can then be magnetically attached to the support member 21. After folding the support member 21, the wireless charger is accurately fixed to the back of the phone for wireless charging. Normal use of the phone, such as watching videos or playing games, will not cause the phone to shift, ensuring uninterrupted charging.

[0122] In other embodiments, for ease of installation, multiple first magnetic units 31 can be arranged on a support member. The support member can be, for example, an arc-shaped iron sheet (with the same structure as the second cover member 212 in Figure 45). The first magnetic units 31 can be magnetically attracted to this support member and fixed with adhesive for easy arrangement. When installing the magnetic assembly 30 in the first mounting groove 2111, the support member and the first magnetic units 31 can be installed simultaneously in the first mounting groove 2111, making installation more convenient. Furthermore, the support member can be installed facing inwards (i.e., the support member is located between the bottom of the first mounting groove 2111 and the first magnetic unit 31), or the support member can be installed facing outwards (i.e., the first magnetic unit 31 is located between the bottom of the first mounting groove 2111 and the support member), depending on the requirements.

[0123] Furthermore, referring to Figures 45 and 46, a second cover 212 can be attached to the opening of the first mounting groove 2111. The second cover 212 not only makes the surface of the support body 211 flat and aesthetically pleasing, but also covers the magnetic component 30, preventing it from falling out of the first mounting groove 2111, and protects the magnetic component 30 from damage. The second cover 212 is, for example, a sheet made of one or more materials such as PC (polycarbonate), silicone, and TPU (thermoplastic polyurethane elastomer). The shape of the second cover 212 is the same as that of the magnetic component 30, both being arc-shaped.

[0124] Furthermore, referring to Figures 45 and 46, the support body 211 is an annular structure with an opening. The opening breaks the annular structure, making the ring not closed. Simultaneously, an insulating component 214 bridges the two ends of the support body 211 located at the opening. Specifically, since the support body 211 is made of metal or alloy, when the magnetic wireless charger charges the phone, the annular metal support body 211, located between the wireless receiving coil inside the phone and the wireless transmitting coil inside the wireless charger, will experience electromagnetic induction. This will generate current in the annular metal support body 211, and the current flowing through it will form eddy currents. This will cause the support body 211 to heat up rapidly. When the phone or wireless charger detects the high temperature, it will usually activate a self-protection mechanism, reducing charging efficiency or directly interrupting the charging process. Therefore, by making the support body 211 open, preventing the metal from forming a complete ring, the formation of eddy currents on the support body 211 can be effectively avoided, thus solving the problem of the support body 211 overheating. Meanwhile, to ensure the strength and user experience of the support body 211, an insulating component 214 bridges the two ends of the support body 211 at the opening. The support body 211 and the insulating component 214 together form a complete ring structure. The insulating component 214 is made of one or more of the following non-metallic materials: PC (polycarbonate), silicone, TPU (thermoplastic polyurethane elastomer), nylon, and glass fiber. For example, it can be made of nylon alone or a mixture of nylon and glass fiber. Specifically, the two ends of the support body 211 at the opening are recessed to form grooves, and protruding connecting posts are provided within these grooves. The thickness of the two ends of the insulating component 214 is thinner than that of the middle portion, and connecting holes are provided at both ends. The connecting holes fit onto the connecting posts, and pressure is applied to the ends of the connecting posts to deform them, preventing the connecting posts from detaching from the connecting holes, thus achieving a riveted connection between the insulating component 214 and the support body 211. In other embodiments, the insulating component 214 can also be connected to the support body 211 by means of adhesive bonding, injection molding, etc.

[0125] Furthermore, a handle can be provided on the insulating component 214, which allows the user to easily grip it with their fingers to pull up the support component 21, causing the support component 21 to rotate relative to the base 22. Of course, in other embodiments, if the support body 211 is made of non-metallic materials such as PC (polycarbonate) or composite board, then a separate insulating component 214 is not required.

[0126] Referring further to Figures 41, 42, 45, and 46, the support member 21 also includes a hinge 213. The support body 211 has a hinge fixing part 2112, with two arc-shaped magnetic suction components 30 on either side of the hinge fixing part 2112. The hinge fixing part 2112 has multiple protruding connecting posts 2113, and the hinge 213 has multiple connecting through holes 2131 and a bushing part 221. The connecting through holes 2131 fit onto the connecting posts 2113, applying pressure to deform the ends of the connecting posts 2113, preventing the connecting posts 2113 from detaching from the connecting through holes 2131, thus achieving a riveted and fixed connection between the hinge 213 and the hinge fixing part 2112. In other embodiments, the hinge 213 can also be connected to the hinge fixing part 2112 by welding, bonding, injection molding, or other methods. The hinge 213 and the support body 211 can be two parts connected by various methods, or they can be integrally molded by injection molding or similar processes. The hinge 213 can be made of metal or alloy, such as steel or manganese alloy steel.

[0127] Furthermore, the bracket assembly 20 also includes a rotating shaft 23, which is connected to the bushing portion 221 on the hinge 213 and the base 22 respectively, realizing the rotational connection between the support member 21 and the base 22. The rotating shaft 23 and the bushing portion 221 on the hinge 213 are in a damped rotational fit. Referring to Figures 43 and 44, the base 22 includes a base body 222 and an intermediate connecting member 225. The base body 222 is connected to the intermediate connecting member 225, and the edges of the base body 222 and the intermediate connecting member 225 are spaced apart from each other, forming a groove 220 between them. The base mounting portion 111 on the back plate 11 is a through hole, and the side wall of the through hole (i.e., a part of the back plate 11) is engaged in the groove 220 so that the base 22 is installed in the base mounting portion 111 and can rotate within the base mounting portion 111. Specifically, the base body 222 has a connecting portion 2222 protruding on one side facing the intermediate connector 225. There can be one or more connecting portions 2222. Correspondingly, the intermediate connector 225 is provided with a connecting hole 2251. There can be one or more connecting holes 2251. During installation, the base body 222 is placed outside the through hole on the back plate 11, and the intermediate connector 225 is placed inside the through hole on the back plate 11. The connecting portion 2222 passes through the through hole on the back plate 11 and through the connecting hole 2251 on the intermediate connector 225. Then, pressure is applied to the end of the connecting portion 2222 to deform it, so that the connecting portion 2222 will not detach from the connecting hole 2251, thereby achieving the riveting and fixing of the base body 222 and the intermediate connector 225. At the same time, the side wall of the through hole is sandwiched between the base body 222 and the intermediate connector 225. At this time, the base 22 can rotate within the through hole without falling out of the through hole.

[0128] Furthermore, referring to Figures 37 to 40, a first base connector 61 can be embedded or covered on the side wall of the through hole on the back plate 11. The first base connector 61 has an annular structure, with one part embedded in the side wall of the through hole and the other part exposed and located in the slot 220 on the side of the base 22, so that the base 22 can be relatively fixed relative to the first base connector 61 in the thickness direction of the back plate 11, and the base 22 can rotate relative to the back plate 11 in the circumferential direction, as shown in Figure 38, which illustrates the connection structure between the base 22 and the back plate 11. Referring to Figures 39 and 40, the annular body of the first base connector 61 has a connecting portion extending from its side. The connecting portion and part of the annular body are embedded in the side wall of the through hole, and the other part of the annular body is exposed in the through hole to be held in the slot 220 formed between the base body 222 and the intermediate connector 225, so that the base 22 and the back plate 11 can be rotatably connected. Since the backplate 11 of the protective case is usually made of plastic such as PC (polycarbonate), while the base 22, which needs to be rotatably connected to the support 21, is usually made of metal such as stainless steel or aluminum alloy to ensure the strength of the connection, if the base 22 rotates and rubs against the backplate 11, the sidewalls of the through holes on the backplate 11 will wear quickly, resulting in a short service life of the bracket and increasing the cost of using the protective case for the user. This problem can be effectively solved by setting a first base connector 61. The first base connector 61 can be made of a high-hardness metal or alloy such as stainless steel or iron, or it can be made of a high-hardness, wear-resistant non-metallic material. The first base connector 61 replaces the sidewalls of the through holes in rubbing against the base 22. Since both are high-hardness materials, the wear during rotation is small, thus effectively improving the service life of the protective case.

[0129] Furthermore, the base body 222 is also provided with shaft holes 2223. There are two shaft holes 2223, which are arranged opposite each other. Between the two shaft holes 2223 is a bushing receiving cavity. The bushing part 221 on the support member 21 is located in the bushing receiving cavity. The two sides of the rotating shaft 23 have cutting planes. The bushing part 221 is a rolled structure formed by winding the end of the hinge 213. The middle part of the rotating shaft 23 is located in the bushing part 221 and is damped and rotated with the bushing part. The two ends of the rotating shaft 23 extend out of the bushing part 221 and are inserted and fixed in the shaft holes 2223, realizing the damped rotational connection between the support member 21a and the base 22. This allows the support member 21a to be opened to any angle and positioned relative to the base 22, realizing multi-angle support. Correspondingly, the intermediate connector 225 is provided with a first clearance hole 2252 at the position corresponding to the bushing cavity. When the bracket rotates, a part of the bushing 221 can extend into the first clearance hole 2252 to avoid the intermediate connector 225 from interfering with the rotation of the bracket, so that the overall structure of the base 22 is more compact and the thickness is compressed.

[0130] Furthermore, on one side of the base body 222 facing the intermediate connector 225, there is also an installation cavity 2221. A rotation limiting component 50 is arranged in the installation cavity 2221. The rotation limiting component 50 includes a first limiting part 51 and an elastic part 53. One end of the elastic part 53 abuts against the side wall of the installation cavity 2221, and the other end abuts against the first limiting part 51. A part of the first limiting part 51 can extend out of the installation cavity 2221 and into the card slot 220 on the side of the base 22 under the action of the elastic part 53. At the same time, a second limiting part 52 is arranged on the side wall 611 of the first base connector 61. The second limiting part 52 can be, for example, a groove structure. A part of the first limiting part 51 can extend into the second limiting part 52 under the action of the elastic part 53 to realize the limit of the relative rotation of the base 22 with respect to the back plate 11. Correspondingly, a second avoidance hole 2253 is formed at the position of the intermediate connector 225 corresponding to the installation cavity 2221. A part of the elastic part 53 can extend into the second avoidance hole 2253 to make the overall structure of the base 22 more compact and the thickness reduced.

[0131] Furthermore, continue to refer to FIG. 44. The installation cavity 2221 is an installation groove arranged on the base body 222. The installation groove is generally in the shape of a Chinese character "zhong" or a T shape. The first limiting part 51 includes a U-shaped main body, and two end parts of the U-shaped main body at the opening face in opposite directions and bend and extend away from the inside of the U-shaped main body to form two limiting ends. Among them, the U-shaped main body of the first limiting part 51 is located in the groove of the vertical part of the Chinese character "zhong" - shaped or T - shaped installation groove, and the two limiting ends are respectively located in the grooves of the horizontal parts of the Chinese character "zhong" - shaped or T - shaped installation groove and respectively abut against the side walls of the installation groove to limit the size of the part of the bottom of the U-shaped main body protruding out of the installation groove. At the same time, the two limiting ends of the first limiting part 51 can move in the grooves of the horizontal parts of the installation groove to ensure that the first limiting part 51 can move in the direction of the groove of the vertical part of the installation groove. The first limiting part 51 can extend out of the installation groove or retract into the installation groove under the action of the elastic part 53. When the first limiting part 51 extends out of the installation groove, it abuts and cooperates with the second limiting part 52 to realize the limit of the relative rotation of the base 22 with respect to the back plate 11.

[0132] Furthermore, referring to FIG. 43, on one side of the base body 222 away from the intermediate connector 225, an avoidance part 2224 is recessed. A step is formed between the avoidance part 2224 and the surface of the base body 222. When the support member 21 is stored, a part of the support member 21 is stacked on the step to realize the avoidance of the support member 21 and ensure that when the support member 21 is stored, the support member 21 is flush with the base 22.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
