In order to facilitate carrying the wireless charger together with the mobile phone and holding the mobile phone during charging, some wireless chargers are provided with a back ring. For the related structure, please refer to the Chinese patent publication document with the publication number CN220553849U and the name "A Wireless Charger Ring Buckle Structure and a Wireless Charger", which records: "It includes a rear shell and a ring. A circular convex ring is formed at the center of the bottom surface of the rear shell. An articulated arm is provided at the edge of the ring. The articulated arm protrudes towards the rear shell, and an arc transition part is formed at the connection between the articulated arm and the ring. A bushing is formed at one end of the articulated arm away from the arc transition part, and the bushing protrudes towards the rear shell. A first stepped groove is formed on the circular convex ring, and a second stepped groove is formed at the edge of the circular convex ring.

[0020] The present utility model will be described in more detail below with reference to the drawings and embodiments.

[0021] The present utility model discloses a double-sided magnetic adsorption wireless charger with a 360° rotatable bracket. As shown in Figures 1 to 5 , it includes a housing 1, a rotating ring 2 and a support ring 3. The top and bottom sides inside the housing 1 are respectively provided with a first wireless charging module 4 and a second wireless charging module 5. The rotating ring 2 is rotatably connected to the bottom of the housing 1, and the rotating ring 2 surrounds the outside of the second wireless charging module 5. The edge of the support ring 3 is hingedly connected to the edge of the rotating ring 2 by means of a damping shaft assembly 6. The bottom of the housing 1 is provided with an elastic limiting mechanism 7 for angularly limiting the rotating ring 2.

[0022] In the above structure, the first wireless charging module 4 on the top side of the housing 1 is used to charge a mobile phone, and the second wireless charging module 5 on the bottom side of the housing 1 is used to charge a smart watch. The housing 1 is magnetically coupled with the mobile phone by a magnetic attraction mechanism inside it, so as to adsorb the wireless charger on the back of the mobile phone. When the user needs to adjust the orientation of the support ring 3, only need to apply force to the support ring 3 or the rotating ring 2, so that the rotating ring 2 rotates to the corresponding position, thus facilitating the finger to pass through the support ring 3, or facilitating the use of the support ring 3 to support the wireless charger and the mobile phone. At the same time, the elastic limiting mechanism 7 can limit the rotating ring 2 at the rotated angle, and the damping shaft assembly 6 can make the support ring 3 and the rotating ring 2 be in damping cooperation, so that the support ring 3 can fully exert its supporting ability for the mobile phone and the wireless charger. Based on the above structure and principle, the present utility model can conveniently adjust the orientation of the support ring, which is convenient for the finger to pass through and can also reliably support the mobile phone.

[0023] Regarding the preferred rotation mode of the rotating ring 2, in this embodiment, a bottom cover 10 is fixed to the top of the housing 1. There is an annular gap between the edge of the bottom cover 10 and the bottom of the housing 1. The inner ring end of the rotating ring 2 is clamped in the annular gap, and the rotating ring 2 is rotatably matched with the bottom cover 10. In the above structure, by setting the annular gap, not only can the inner ring end of the rotating ring 2 be accommodated, but also the junction position between the rotating ring 2 and the bottom cover 10 can be hidden, which has the function of preventing dust.

[0024] In order to facilitate charging the smart watch, in this embodiment, the charging surface of the second wireless charging module 5 is attached to the bottom cover 10. In practical applications, a central magnet for magnetic coupling with the watch is provided at the center of the second wireless charging module 5.

[0025] Regarding the preferred structure of the elastic limiting mechanism 7, in this embodiment, please refer to Figure 1 and Figure 5, the elastic limiting mechanism 7 includes a spring 71 and a slider 72. A slider support 11 is provided at the bottom of the housing 1. The slider 72 is arranged in the slider support 11, and the slider 72 can slide radially along the rotating ring 2. The spring 71 abuts against the slider 72, and the spring 71 is used to apply an elastic stress to the slider 72 to slide outward. Wave-shaped limiting ports 20 are evenly distributed at the inner ring end of the rotating ring 2. A protruding end 73 is formed at one end of the slider 72 away from the spring 71, and the protruding end 73 is clamped in the wave-shaped limiting port 20. In the above structure, one end of the spring 71 abuts against the bottom of the housing 1, and the other end of the spring 71 abuts against the slider 72, so as to apply an elastic stress for the slider 72 to slide outward, and further enable the protruding end 73 at the end of the slider 72 to be in good match with the wave-shaped limiting port 20. After the rotating ring 2 rotates to a specified angular position, the rotating ring 2 is restricted at the rotated position by using the elastic limiting function of the above elastic limiting mechanism 7.

[0026] In order to better accommodate the slider 72 and improve the matching performance with the slider 72, in this embodiment, the slider support 11 is an inverted "U" - shaped support integrally formed with the housing 1.

[0027] On this basis, two auxiliary stoppers 12 are formed at the bottom of the housing 1. The auxiliary stoppers 12 abut against the inner ring end of the rotating ring 2 and are in sliding fit with each other. In practical applications, the housing 1 is a circular housing, and the two auxiliary stoppers 12 and the protruding end 73 are evenly distributed on the same circular track on the back of the housing 1.

[0028] As a preferred method, please refer to Figure 4 , the damping shaft assembly 6 includes a first damping sleeve 60, a second damping sleeve 61 and a damping shaft 62. The first damping sleeve 60 is fixedly connected to the support ring 3, the second damping sleeve 61 is fixedly connected to the rotating ring 2, the damping shaft 62 passes through the first damping sleeve 60 and the second damping sleeve 61, and the damping shaft 62 is in damping fit with both the first damping sleeve 60 and the second damping sleeve 61. The above damping shaft assembly 6 has the characteristics of simple structure and reliable support relationship.

[0029] In order to better magnetically cooperate with the back of the mobile phone, in this embodiment, a face cover 13 is provided at the top of the housing 1, and a positioning magnetic ring assembly 14 is provided outside the first wireless charging module 4.

[0030] The above are only the preferred embodiments of the present invention and are not used to limit the present invention.
