[0002] A mobile phone bracket, also known as a lazy bracket, can be designed into different mobile phone brackets according to different models and brands of digital products such as tablet computers, mobile phones, cameras, etc. A mobile phone bracket is a bracket used to support the use of such digital products. According to ergonomics, it can make the use of digital products more comfortable, avoid cervical spondylosis, and enable users to obtain a better user experience.

[0003] Mobile phone brackets include desktop brackets, in-vehicle brackets, bed brackets, cycling brackets, etc. At present, some mobile phone brackets have the functions of magnetic positioning or magnetic charging, and are applicable to MagSafe technology. The mobile phone is fixed to the mobile phone bracket through magnetism.

[0004] For example, in the prior art (Publication No.: CN218336104U, Publication Date: January 17, 2023), a magnetic wireless charging mobile phone bracket is disclosed, which adsorbs the mobile phone to the wireless charging panel through a magnetic module for charging.

[0005] Since the magnetic modules of such products do not have the function of adjustable magnetism, it is relatively laborious to remove the mobile phone from such products, resulting in inconvenient use. Therefore, it is necessary to design a mobile phone bracket that automatically eliminates magnetism when removing the mobile phone to solve the above problems. Summary of the Utility Model

[0006] The utility model provides a technical solution that can solve the above problems to overcome the above deficiencies.

[0007] A mobile phone bracket with adjustable magnetism includes a bracket body. A backboard is arranged in the middle of the bracket body, and a magnetic force adjusting mechanism is fixedly installed in the backboard.

[0008] The magnetic force adjusting mechanism includes a base, a motor and a permanent magnet ring. The base is fixedly installed on the inner side of the backboard, the motor is fixedly installed in the middle of the base, and the motor drives the permanent magnet ring to be close to or far away from the backboard.

[0009] An inductor is inlaid and installed on the backboard, and the inductor controls the motor to work.

[0010] As a further solution of the utility model: the magnetic adjustment mechanism also includes a screw, a nut and a telescopic slider. The telescopic slider is in an annular structure and is sleeved on the outside of the base. The screw is integrally formed on the rear side of the base. The screw is hollow. The motor is fixedly installed in the screw. The nut is spirally installed on the screw. The rotor of the motor drives the nut to rotate. When the nut rotates, it drives the telescopic slider to slide back and forth on the outside of the base. The permanent magnet ring is fixedly installed on the telescopic slider.

[0011] As a further solution of the utility model: a wireless charging transmitting coil is fixedly installed in the back plate, and the wireless charging transmitting coil is arranged on the inner side of the permanent magnetic ring.

[0012] As a further solution of the utility model: a power input port is fixedly installed on the side of the back plate, and the power input port supplies power to the motor and the wireless charging transmitting coil.

[0013] As a further solution of the utility model: the power input port adopts any one of the type-c female socket, micro female socket, lightning female socket, and DC interface.

[0014] As a further solution of the utility model: the sensor adopts any one of an infrared induction switch, a microwave induction switch, an ultrasonic induction switch, a piezoelectric induction switch, an electromagnetic induction switch, and a capacitive induction switch.

[0015] As a further solution of the utility model: the bracket body adopts any one of a car-mounted mobile phone bracket, a desktop mobile phone bracket, and a lazy mobile phone bracket.

[0016] Compared with the prior art, the beneficial effects of the utility model are: the sensor can sense whether the mobile phone is placed on the back plate. When the mobile phone is placed on the back plate, the motor drives the permanent magnetic ring close to the back plate, and the back of the mobile phone can be fixed to the back plate by the magnetic attraction of the permanent magnetic ring. When the mobile phone needs to be taken off, the sensor is used to sense the action of taking off the mobile phone. The sensor drives the permanent magnetic ring away from the back plate through the motor, thereby eliminating the magnetic force of the mobile phone on the back plate, making it convenient to take off the mobile phone without any effort, and convenient for practical use.
