Description

[0001] The utility model relates to the technology in the field of mobile terminal brackets, in particular to a magnetic bracket. Background Art

[0002] With the popularization of mobile terminals such as smart phones, the usage frequency of various applications of mobile terminals has gradually increased. To free hands for watching mobile terminals such as mobile phones, mobile terminal brackets such as mobile phone brackets have well solved this problem. Traditional mobile terminal brackets such as mobile phone brackets are mechanical structure brackets, which are fixed stably but have a relatively complex structure, and it is not convenient to take out mobile terminals such as mobile phones. Therefore, magnetic brackets have emerged one after another.

[0003] For example, a magnetic mobile phone bracket disclosed in Chinese Patent Publication No. CN219459128U includes a base, a support rod and a support main board. One end of the support rod is rotatably connected to the support main board, and the other end is rotatably connected to the base. A magnetic component is arranged on the support main board. In this way, it can magnetically adsorb and fix the mobile phone by magnetic attraction. Although it can fixedly install a magnet on the support main board and use the magnet to adsorb a mobile phone with magnetic attraction function, and the mobile phone can be stably adsorbed by the magnet with strong adsorption force. However, in order to enable the mobile phone to be switched between horizontal and vertical positions, the mobile phone needs to be rotated by operating the mobile phone to overcome the strong adsorption force of the magnetic adsorption component, so that the mobile phone can rotate frictionally relative to the magnetic adsorption component to adjust the rotation angle of the mobile phone and realize the horizontal and vertical switching placement of the mobile phone.

[0072] Please refer to Figures 1 to 18 as shown, which shows the specific structures of the magnetic adsorption brackets provided by three embodiments of the present utility model; among them, Figures 1 to 6 shows the specific structure of the magnetic adsorption bracket provided by Embodiment 1, Figures 7 to 12 shows the specific structure of the magnetic adsorption bracket provided by Embodiment 2, Figures 13 to 18 shows the specific structure of the magnetic adsorption bracket provided by Embodiment 3, Figure 19 shows the specific structure of the magnetic adsorption bracket provided by Embodiment 4.

[0073] As Figures 1 to 6 shown, in Embodiment 1, a magnetic adsorption bracket includes a base 10, and a magnetic adsorption component for adsorbing a mobile terminal is arranged on the base 10; the magnetic adsorption component includes a rotating seat 20 and a magnetic adsorption member 30 fixedly installed on the rotating seat 20, the rotating seat 20 is rotatably connected to the base 10, and the relative rotation between the rotating seat 20 and the base 10 is restricted by an elastic positioning component 40. Specifically, the elastic positioning component 40 is installed on the rotating seat 20, the elastic positioning component 40 includes an elastic member and a positioning member, and the base 10 is provided with a plurality of positioning portions arranged in sequence along the rotation direction of the rotating seat 20 (in other embodiments, the elastic positioning component 40 can be installed on the base 10, and the rotating seat 20 is provided with a plurality of positioning portions arranged in sequence along the rotation direction of the rotating seat 20), and the positioning member is positioned in the positioning portion under the elastic force of the elastic member; when the rotating seat 20 rotates relative to the base 10, the positioning member can overcome the elastic force of the elastic member and disengage from the positioning portion; the rotating seat 20 and the base 10 are in contact through a contact strip 11, which can reduce the contact area between the two and make the rotation smoother; the contact strip 11 is preferably a rib strip in a ring shape.

[0074] As Figures 1 to 6 shown, in Embodiment 1, the base 10 includes a seat body 12 and a ball head connecting member 13 integrally formed and connected to the rear end of the seat body 12. In this way, the ball head connecting member 13 can be integrally formed on the base 10, simplifying the connection structure between the ball head connecting member 13 and the base 10. The rotating seat 20 is rotatably connected to the seat body 12, and the ball head connecting member 13 is fixedly connected to the bracket with a ball head by screwing a nut tightly.

[0075] As Figures 1 to 6As shown, in the first embodiment, a ring-shaped silicone pad 50 is provided on the side of the magnetic suction member 30 away from the rotating seat 20, and the silicone pad 50 is exposed on the surface of the rotating seat 20 and the base 10. In this way, when the mobile terminal is adsorbed on the magnetic suction bracket, the mobile terminal is only in contact with the silicone pad 50, so that the mobile terminal can avoid contact with the rotating seat 20 and the base 10 to generate friction during the rotation process, thereby preventing the mobile terminal from being worn during the rotation process. In addition, the upper surface of the rotating seat 20 is concavely provided with an annular positioning groove 21, and the magnetic suction member 30 is an annular magnet assembly, which is installed in the annular positioning groove 21.

The elastic positioning assembly 40 also includes a sleeve 41, the elastic member is arranged in the sleeve 41, one end of the positioning member extends into the sleeve 41 and abuts against the elastic member, and the other end of the positioning member extends out of the sleeve 41, and the outer peripheral side wall of the rotating seat 20 is concavely provided with a mounting hole 22, the sleeve 41 is installed in the mounting hole 22, and the other end of the positioning member extends out of the mounting hole 22; preferably, the positioning part is a card slot 14, and a plurality of connected card slots 14 are sequentially arranged on the inner peripheral side wall of the base 10 around the circumferential direction of the base 10, so that the plurality of card slots 14 are arranged in a ring shape. The positioning member is a ball 42, and the elastic member is a spring 43. The ball 42 is stuck in the slot 14 under the elastic force of the spring 43 to limit the rotation of the magnetic suction component relative to the base 10; when the rotating base 20 rotates relative to the base 10, the ball 42 can overcome the elastic force of the spring 43 and disengage from the slot 14, so that the ball 42 can rotate relative to the base 10 after exiting the slot 14, so that after the mobile phone is adsorbed on the rotating base 20, the mobile phone and the rotating base 20 are rotated together to adjust the angle, so that the mobile phone can be switched between horizontal and vertical placement.

[0078] like Figures 2 to 6As shown, in the first embodiment, the base 10 is provided with a groove 15. Specifically, the groove 15 is provided on the seat body 12. The rotating seat 20 is installed in the groove 15, so that the rotating seat 20 can be sunk into the base 10, which can save the occupied space and thus reduce the overall thickness.

The extension portion 62 and the base 10 are locked and connected by a screw 64 passing through the first connecting through hole 17 and the second connecting through hole 63. The front side of the rotating seat 20 is in contact with the rear side of the body portion 61 through a first protrusion 201. Specifically, a concave cavity 25 is recessed on the front side of the rotating seat 20. The body portion 61 is located in the concave cavity 25. The rear side of the body portion 61 is limited by the bottom wall of the concave cavity 25. The bottom wall of the concave cavity 25 is convex with a first protrusion 201. The first protrusion 201 is an annular rib, and this rib is used to contact the rear side of the body portion 61, so that the contact area between the rotating seat 20 and the body portion 61 is reduced during the rotation process of the rotating seat 20, so as to reduce the friction on the rotating seat 20 and make the rotating seat 20 easy to rotate smoothly. A clamping groove 65 is opened at the lower end of the extension portion 62. A clamping portion 18 is convex on the bottom of the connecting groove 16. The clamping portion 18 is clamped with the clamping groove 65, so as to prevent the connecting member 60 from rotating when the screw 64 is locked and connected, and it is convenient to lock the connecting member 60 on the base 10.
