The magnetic module 2 is arranged in the movable seat 1. In this embodiment, the base 3 and the movable seat 1 are square in shape and are cubic as a whole. A wireless charging coil is provided on the magnetic module 2. That is, on the basis of magnetic fixation, a wireless charging function is added to realize magnetic fixation and wireless charging. In other embodiments, a wireless charging coil may not be provided and only a magnetic function may be provided.

[0023] The base 3 is provided with a connection hole 321 at the center of the bottom, and two slopes 322 are symmetrically arranged along the circumferential direction of the connection hole 321 at the periphery thereof. Specifically, the base 3 includes a bottom shell 31, a transfer shell 32, and an upper cover 33. The connection hole 321 is located on the transfer shell 32, and an arc-shaped through hole 323 is provided around the connection hole 321. The bottom shell 31 is provided with a connection column 311 passing through the arc-shaped through hole 323. The upper cover 33 is fixed on the connection column 311. The transfer shell 32 can be rotated at a certain angle by the arc-shaped through hole 323. The connection hole 321 is located at the center of the transfer shell 32.

[0024] The pull rod portion 41 of the suction cup 4 passes through the connecting hole 321, and the pull shaft 7 radially passes through the pull rod portion 41, and both ends are located on the slope 322. Preferably, the highest position of the slope 322 is a plane, and a positioning groove 324 is provided on the plane. When the pull shaft 7 slides to the highest position of the slope 322, it is just stuck in the positioning groove 324, and the positioning effect is good.

[0025] The lower end of the lower arm 9 is hinged to the base 3 through a first damping shaft 10, the upper end of the lower arm 9 is connected to the lower end of the upper arm 8 through a straight damping shaft 12, and the upper end of the upper arm 8 is hinged to the movable seat 1 through a second damping shaft 11.

[0026] Preferably, a reset spring 13 is provided between the base 3 and the suction cup 4. Specifically, the lower end of the reset spring 13 abuts against the suction cup 4, and the upper end passes through the bottom shell 31 and presses against the intermediate shell 32. When the pull shaft 7 leaves the positioning groove 324, the pull shaft 7 quickly slides from the highest position of the slope 322 to the lowest position due to the push of the reset spring 13, so that the suction cup 4 can be quickly reset. Preferably, a conical cavity adapted to the suction cup 4 is provided on the bottom surface of the bottom shell 31, a circular platform 312 is provided on the upper surface of the bottom shell 31, a circular cavity adapted to the circular platform 312 is provided at the lower part of the intermediate shell 32, and positioning teeth 325 arranged along its circumferential direction are provided on the inner wall of the circular cavity, and a rotating sound-generating device 5 adapted to the positioning teeth 325 is provided on the circular platform 312. Specifically, the rotational sound-generating device 5 includes a locking tongue 51 and a positioning spring 52. A positioning cavity is provided on the circular platform 312. The positioning spring 52 and the locking tongue 51 are located in the positioning cavity, and the positioning spring 52 can push the front end of the locking tongue 51 forward to press against the positioning tooth 325. When rotating, it has a rotational locking sound-generating effect and a positioning effect.

[0027] In order to facilitate the removal of the suction cup 4, the utility model further includes a suction cup pressure relief device 6, which includes a pressure relief button 61 and a pressure-maintaining valve 62. The suction cup 4 is provided with a pressure relief hole 42, and the pressure-maintaining valve 62 is arranged on the circular platform 312 of the intermediate shell 32. The air outlet pipe 63 of the pressure-maintaining valve 62 is connected to the pressure relief hole 42, and the pressure relief button 61 is arranged on the intermediate shell 32 corresponding to the valve handle position of the pressure-maintaining valve 62. When rotating, the pressure relief button 61 rotates with the intermediate shell 32, and after being staggered with the valve handle of the pressure-maintaining valve 62, pressure relief cannot be performed; only when the pressure relief button 61 is rotated to the initial position so that the valve handle of the pressure-maintaining valve 62 is relatively aligned, can pressure relief be performed by pressing the pressure relief button 61.

[0028] When in use, the suction cup 4 is pressed on the car windshield or other car interior panels with a smooth surface, and then the pull shaft 7 is slid to the highest position of the slope 322 by rotating the intermediate shell 32 to stretch the suction cup 4 to form a negative pressure, so that it can be quickly sucked and fixed on the car windshield or other car interior panels with a smooth surface; in addition, when the intermediate shell 32 is rotated, there is a rotation and locking sound effect, providing additional feedback and prompt functions. At the same time, the pressure relief button 61 rotates with the rotation of the intermediate shell 32, and after being staggered with the valve handle of the pressure-maintaining valve 62, it cannot release pressure to prevent misoperation.

[0029] At this time, the mobile phone can be placed directly on the movable seat 1 and fixed by the magnetic module 2; then, through the cooperation of the upper arm 8, the lower arm 9, the first damping shaft 10, the second damping shaft 11 and the straight damping shaft 12, the height and rotation angle of the movable seat 1 can be adjusted at any time to adjust the mobile phone to the desired position and angle.

[0030] When disassembly is required, the transfer shell 32 is rotated in the opposite direction to the initial position so that the pressure relief button 61 is aligned with the valve handle of the pressure maintaining valve 62. Only then can the pressure relief button 61 be pressed to trigger the pressure maintaining valve 62 to relieve pressure, thereby relieving pressure from the suction cup 4 and making it easier to remove the suction cup 4.

[0031] Example 2, see Figure 6 to Figure 7 The present embodiment provides a suction cup type magnetic bracket, which is basically the same as the structure of the embodiment 1, except that the base 3 and the movable seat 1 are circular in shape and cylindrical in shape as a whole.
