[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods. The terms such as "upper", "lower", "left", "right", "middle" and "one" used in the preferred embodiments are only used to facilitate the description, and are not used to limit the scope of the implementation of the present invention. The changes or adjustments in their relative relationships shall also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0024] like Figure 1 , 2 As shown in Figures 1 and 3, the utility model provides a magnetic external rotating bracket with a gear positioning structure, including a support member 1, a hinge member 2, a magnet 5, a rotating base 4 and a fixed base 6. The magnet 5, the rotating base 4 and the fixed base 6 form a base body that fits on the electronic device, and the support member 1 is opened at a certain angle relative to the base body, thereby playing a role as a bracket, so as to support electronic products such as mobile phones and tablets placed on the desktop at a certain angle.

[0025] The support member 1 is connected to the rotating base 4 via the hinge 2. The support member 1 rotates on the rotating base 4 around the hinge 2, so that it can be fitted with the rotating base 4 or opened at a certain angle, and the support member 1 can realize the support function when it is in the open state. The hinge 2 is a hinge or other axial connection.

[0026] The rotating base 4 and the fixed base 6 are both designed with circular structures. The rotating base 4 is rotatably arranged on the fixed base 6, and its purpose is to make the support member 1 rotate relative to the fixed base 6 through the rotating base 4, so as to change the support direction when used as a bracket. The central area of ​​the rotating base 4 is provided with a circular groove that rotates with the fixed base 6, and the central area of ​​the fixed base 6 is provided with a circular buckle 62 that rotates with the rotating base 4. The circular buckle 62 is sleeved in the circular groove, and a circle of continuous gear grooves 42 are provided on the inner circumference of the circular groove. A clamp head that elastically contacts the gear groove 42 is provided on the outer circumference of the circular buckle 62. When the rotating base 4 and the fixed base 6 rotate relative to each other, due to the continuous gear groove 42, a damping effect is generated between the clamp head and the gear groove 42, thereby preventing the rotating base 4 from rotating freely on the fixed base 6, which is convenient for user operation, so that the rotating base 4 and the fixed base 6 can rotate only when the rotation force between them reaches a certain level. In order to improve the reliability of the connection between the rotating base 4 and the fixed base 6, a mushroom-shaped shaft head 41 is provided in the central protrusion of the circular groove, and an shaft hole 61 is provided in the center of the annular buckle 62. The mushroom-shaped shaft head 41 is rotatably and snap-fittedly connected to the shaft hole 61.

[0027] There are multiple magnets 5, which are arranged between the rotating base 4 and the fixed base 6 and around the outer circumference of the circular groove. The magnetic external rotating bracket is fixed to the main body shell or protective shell of the electronic device by adsorption through the magnet 5. When the main body shell or protective shell of the electronic device is made of plastic material and cannot be directly magnetically adsorbed, a magnetic attraction sheet can be arranged on it to achieve the purpose of adsorption and fixation.

[0028] In order to improve the flatness of the bottom surface of the fixed base 6 and facilitate the connection with the main body shell or protective shell of the electronic device, a bottom shielding sheet 7 is attached to the bottom surface of the fixed base 6. Preferably, the bottom shielding sheet 7 is provided with double-sided adhesive, and in addition to the magnetic connection, it can also be bonded and connected with the main body shell or protective shell of the electronic device through the double-sided adhesive.

[0029] In a specific embodiment, the rotating base 4 and the fixed base 6 are both made of plastic material and are formed by injection molding. A riveted metal fixing part 3 is embedded in the position of the rotating base 4 for connecting the hinge 2, and the hinge 2 and the riveted metal fixing part 3 are connected by riveting.

[0030] In another specific embodiment, the support member 1 is annular, and the rotating base 4 is provided with an annular receiving groove that matches the annular support member 1. The rotating base 4 is provided with an annular receiving groove that matches the annular support member 1, and the support member 1 is located in the annular receiving groove when it is attached to the rotating base 4. The user's fingers can pass through the annular support member 1, which can effectively prevent the electronic device from slipping off the fingers when the user uses a mobile phone or other electronic device.

[0031] Preferably, a notch is provided on the side of the support member 1 away from the hinge member 2, and an arc-shaped groove hand buckle position is provided on the annular accommodating groove at a position corresponding to the notch. By setting the arc-shaped groove hand buckle position, the user can conveniently open the support member 1 that is fitted and stored on the rotating base 4.

[0032] Although specific embodiments of the present invention are described above, those skilled in the art should understand that these are merely examples and that various changes or modifications may be made to the embodiments without departing from the principles and essence of the present invention. The scope of protection of the present invention is limited only by the appended claims.
