[0025] See also Figures 1 to 7 The rotary folding bracket 100 of the utility model comprises: an annular fixing ring 10, an annular rotating seat 20, a damping hinge mechanism 30, an annular support seat 40 and an elastic positioning mechanism 50. The annular rotating seat 20 is rotatably arranged on the annular fixing ring 10. One end of the damping hinge mechanism 30 is fixedly connected to the annular rotating seat 20, and the other end of the damping hinge mechanism 30 is fixedly connected to the annular support seat 40. A plurality of positioning slots 21 are also formed on the annular rotating seat 20. The positioning slots 21 are distributed along the circumferential direction of the annular rotating seat 20. The elastic positioning mechanism 50 is arranged along the radial direction of the annular rotating seat 20. The elastic positioning mechanism 50 is detachably elastically engaged in any positioning slot 21. By opening the annular support seat 40 away from the annular rotating seat 20, adjusting the angle between the annular support seat 40 and the annular rotating seat 20, and by the damping positioning effect of the damping hinge mechanism 30, the annular support seat 40 and the annular rotating seat 20 are kept at the angle positioning (such as Figure 7 The annular support seat 40 is in the open support state shown in the figure, and support at different angles can be achieved. By operating the annular rotating seat 20 to rotate relative to the annular fixing ring 10, the elastic positioning mechanism 50 can be elastically engaged in or disengaged from the positioning slot 21 to avoid the annular rotating seat 20 from rotating relative to the annular fixing ring 10. When the annular rotating seat 20 stops rotating relative to the annular fixing ring 10, the elastic positioning mechanism 50 elastically engages in the positioning slot 21 to achieve the support direction of the positioning annular support seat 40, thereby synchronously adjusting the support and stable positioning of the annular support seat 40 in different directions. This makes the structure of the rotary folding bracket 100 of the utility model simpler, the production cost is greatly reduced, the volume is greatly reduced, and it is more convenient to carry. Moreover, the adjustment operation is also simpler and more convenient, the support of the electronic equipment is more stable, the rotation support direction can also be positioned stably, and it is more convenient to use, which greatly improves the user experience.

[0026] Specifically, as follows:

[0027] See also Figures 1 to 6The damping hinge mechanism 30 includes: a first leaf 31, a second leaf 32 and a connecting shaft 33. The first leaf 31 is fixedly connected to the annular support seat 40, and the second leaf 32 is fixedly connected to the annular rotating seat 20. Optionally, in this embodiment, the connecting shaft 33 is rotatably connected to the first leaf 31, and the connecting shaft 33 is fixedly connected to the second leaf 32, so as to realize the installation structure of the damping hinge mechanism 30 connected to the annular rotating seat 20 and the annular support seat 40, and the structure is simpler and more reasonable. Of course, in other embodiments, the connecting shaft 33 can also be selected to be rotatably connected to the second leaf 32, and the connecting shaft 33 is fixedly connected to the first leaf 31, which can also realize the installation structure of the damping hinge mechanism 30 connected to the annular rotating seat 20 and the annular support seat 40. All of these are within the protection scope of the present utility model, so they will not be described in detail here.

[0028] See also Figures 3 to 6 In detail, a first annular clamping wall 311 is formed on the first leaf 31, and the connecting shaft 33 is rotatably inserted in the first annular clamping wall 311; a second annular clamping wall 321 is formed on the second leaf 32, and the connecting shaft 33 is fixedly inserted in the second annular clamping wall 321; a first plane structure 312 is formed on the inner side of the first annular clamping wall 311, and a second plane structure 331 is formed on the connecting shaft 33; when the annular support seat 40 is closed on the annular rotating seat 20, the first plane structure 312 is directly opposed to and abuts against the second plane structure 331. Then, when the annular rotating seat 20 is opened to drive the first leaf 31 to rotate, the first planar structure 312 is away from the second planar structure 331, so that the circumferential side surface of the connecting shaft 33 slides and rubs on the first planar structure 312, so that the circumferential side surface of the connecting shaft 33 is inserted between the arc-shaped inner side surface in the first annular clamping wall 311 and the first planar structure 312 in an interference fit, so as to generate a damping effect on the rotation of the connecting shaft 33, so that the opening of the annular rotating seat 20 to drive the first leaf 31 to rotate can be positioned at any angle, so that the supporting structure is more stable. Moreover, when the annular support seat 40 is about to close on the annular rotating seat 20, the clamping force of the first annular clamping wall 311 on the connecting shaft 33 can drive the first leaf 31 to automatically rotate in the direction of restoring the first plane structure 312 to directly contact the second plane structure 331, until the annular support seat 40 is completely closed on the annular rotating seat 20 (that is, the first plane structure 312 directly contacts the second plane structure 331), which saves effort in operation and is more convenient to use.

[0029] See also Figure 3 and Figure 4The second leaf 32 is fixedly connected to the side of the annular rotating seat 20 facing the annular support seat 40. The annular rotating seat 20 is also formed with an avoidance hole 22. The first annular holding wall 311, the second annular holding wall 321 and the connecting shaft 33 are all located in the avoidance hole 22, and the structure is more reasonable and compact. The side of the annular support seat 40 facing the annular rotating seat 20 is also formed with an installation groove 41. The first leaf 31 is fixedly embedded in the installation groove 41, making the installation of the first leaf 31 more reasonable and compact.

[0030] See also Figure 3 The side of the annular rotating seat 20 facing the annular support seat 40 is recessed in a direction away from the annular support seat 40 to form an annular groove 23, and the annular support seat 40 is detachably accommodated in the annular groove 23. When the annular support seat 40 is closed on the annular rotating seat 20, the annular support seat 40 is accommodated in the annular groove 23, so that the closed annular support seat 40 can be accommodated in the annular groove 23, and the structure is more compact and more convenient to carry.

[0031] See also Figures 1 to 4 An annular limiting groove 24 is also formed on the circumferential side wall of the annular rotating seat 20, and the annular fixing ring 10 is rotatably sleeved in the annular limiting groove 24. Thus, the annular rotating seat 20 is rotatably mounted on the annular fixing ring 10, and the annular rotating seat 20 can be prevented from being separated from the annular fixing ring 10, and the structure is more firm and stable.

[0032] See also Figure 3 and Figure 4 The rotatable folding bracket 100 of the utility model further includes: a plurality of magnetic sheets 60, which are fixedly embedded in the annular support seat 40, and the magnetic sheets 60 are spaced apart along the circumferential direction of the annular support seat 40. On the one hand, when the annular support seat 40 is closed on the annular rotating seat 20, the annular support seat 40 can be automatically adsorbed on the annular rotating seat 20 by the magnetic sheets 60, so as to prevent the annular support seat 40 from accidentally opening. On the other hand, when the rotatable folding bracket 100 of the utility model is arranged on the mobile phone case, that is, the annular fixing ring 10 is fixedly arranged on the back of the mobile phone case, and the annular rotating seat 20 is rotatably arranged on the annular fixing ring 10, the annular rotating seat 20 can be rotatably connected to the back of the mobile phone case, and when the mobile phone is close to the wireless power bank for wireless charging, the magnetic sheet 60 can be magnetically adsorbed on the wireless power bank, thereby ensuring that the mobile phone and the wireless power bank are firmly attached together, preventing the mobile phone from loosening and deviating during charging, causing intermittent charging, and the structure is more reasonable.

[0033] Preferably, in this embodiment, the magnetic sheet 60 is in an arc-shaped structure, and an embedding groove 42 corresponding to the magnetic sheet 60 is formed on the side of the annular support seat 40 facing the annular rotating seat 20, and the magnetic sheet 60 is embedded in the embedding groove 42 one by one. This prevents the magnetic sheet 60 from protruding from the annular support seat 40, and the structure is more reasonable and compact.

[0034] See also Figures 2 to 4 The elastic positioning mechanism 50 includes a sliding card seat 51 and an elastic member 52. The sliding card seat 51 is arranged to move along the radial direction of the annular rotating seat 20. The elastic member 52 is arranged along the radial direction of the annular rotating seat 20. The elastic member 52 always drives the sliding card seat 51 to engage in the positioning card slot 21 facing it. Therefore, the elastic force of the elastic member 52 drives the sliding card seat 51 to elastically engage in or avoid and escape from the positioning card slot 21 facing it.

[0035] Furthermore, the rotary folding bracket 100 of the present invention further comprises a cover plate 70 , which covers the elastic positioning mechanism 50 to cover and protect the elastic positioning mechanism 50 and is more aesthetically pleasing.

[0036] Combined with the accompanying drawings, the working principle of the rotary folding bracket 100 of the utility model is described in detail:

[0037] When the rotatable folding bracket 100 of the utility model is arranged on the mobile phone case, that is, the annular fixing ring 10 is fixedly arranged on the back of the mobile phone case, and the annular rotating seat 20 is rotatably arranged on the annular fixing ring 10, the annular rotating seat 20 can be rotatably connected to the back of the mobile phone case, and a corresponding accommodating groove is provided on the back of the mobile phone case for the sliding card seat 51 and the elastic member 52 to be accommodated and arranged, that is, the sliding card seat 51 slides in the corresponding accommodating groove provided on the back of the mobile phone case, and the elastic member 52 is preferably a spring, and the elastic member 52 is compressed and abuts between the groove wall of the accommodating groove and the sliding card seat 51, so that the elastic member 52 constantly drives the sliding card seat 51 to engage in the opposite positioning card slot 21, and the cover plate 70 is fixed to the back of the mobile phone case, so that the cover plate 70 covers the elastic positioning mechanism 50, so as to play the role of covering and protecting the elastic positioning mechanism 50, and also makes the back of the mobile phone case more beautiful.

[0038] When the rotatable folding bracket 100 of the utility model is used for support, the annular support seat 40 is opened away from the annular rotating seat 20, the angle between the annular support seat 40 and the annular rotating seat 20 is adjusted, and the damping positioning effect of the damping hinge mechanism 30 is used to achieve the angle positioning between the annular support seat 40 and the annular rotating seat 20 (such as Figure 7 The support state shown in the figure is opened), and supports at different angles can be achieved.

[0039] Furthermore, by operating the annular rotating seat 20 to rotate relative to the annular fixed ring 10, the elastic member 52 drives the sliding seat 51 to elastically engage in or disengage from the positioning slot 21, thereby preventing the annular rotating seat 20 from rotating relative to the annular fixed ring 10. When the annular rotating seat 20 stops rotating relative to the annular fixed ring 10, the elastic positioning mechanism 50 elastically engages in the positioning slot 21, thereby realizing the support direction of the positioning annular support seat 40, thereby synchronously adjusting the support and stable positioning of the annular support seat 40 in different directions.

[0040] Since the annular rotating seat 20 of the rotary folding bracket 100 of the utility model is rotatably arranged on the annular fixing ring 10, one end of the damping hinge mechanism 30 is fixedly connected to the annular rotating seat 20, and the other end of the damping hinge mechanism 30 is fixedly connected to the annular support seat 40; the annular rotating seat 20 is also formed with a plurality of positioning slots 21, which are distributed along the circumferential direction of the annular rotating seat 20; the elastic positioning mechanism 50 is arranged along the radial direction of the annular rotating seat 20, and the elastic positioning mechanism 50 is detachably elastically engaged in any positioning slot 21. By opening the annular support seat 40 away from the annular rotating seat 20, adjusting the angle between the annular support seat 40 and the annular rotating seat 20, and realizing the angle positioning between the annular support seat 40 and the annular rotating seat 20 through the damping positioning effect of the damping hinge mechanism 30, support at different angles can be achieved. By operating the annular rotating seat 20 to rotate relative to the annular fixing ring 10, the elastic positioning mechanism 50 can be elastically engaged in or out of the positioning slot 21 to avoid the annular rotating seat 20 from rotating relative to the annular fixing ring 10. When the annular rotating seat 20 stops rotating relative to the annular fixing ring 10, the elastic positioning mechanism 50 elastically engages in the positioning slot 21 to achieve the support direction of the positioning annular support seat 40, thereby synchronously adjusting the support and stable positioning of the annular support seat 40 in different directions. This makes the structure of the rotary folding bracket 100 of the utility model simpler, the production cost is greatly reduced, the volume is greatly reduced, and it is more convenient to carry. Moreover, the adjustment operation is also simpler and more convenient, the electronic equipment is supported more stably, the rotation support direction can also be positioned stably, and the use is more convenient, which greatly improves the user experience.
