[0002] With the popularity of mobile terminals such as smart phones, the frequency of using various applications on mobile terminals has gradually increased. In order to free hands to watch mobile phones and other mobile terminals, mobile phone and other mobile terminal holders have solved this problem well. Traditional mobile phone and other mobile terminal holders are mechanical structure holders, which are fixed and stable but have a complex structure. It is also inconvenient to take out mobile phones and other mobile terminals. For this reason, magnetic holders have been born one after another.

[0003] For example, China Publication No. CN219459128U discloses a magnetic mobile phone holder, which includes a base, a support rod and a support mainboard. One end of the support rod is rotatably connected to the support mainboard, and the other end is rotatably connected to the base. The support mainboard is provided with a magnetic component, so that the mobile phone can be magnetically fixed by magnetic attraction. Although it can absorb the mobile phone by magnet, when the magnetic attraction of the magnet is too strong, the mobile phone is not easy to remove after being absorbed by the magnetic holder; when the magnetic attraction of the magnet is weak, the mobile phone is easy to fall off the magnetic holder when the magnetic holder vibrates, especially when the magnetic holder is installed on a bicycle as a travel holder, the mobile phone is easy to fall off after the magnetic holder is bumped.

[0004] Therefore, it is necessary to develop a new technology to solve the above problems. Utility Model Content

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0040] like Figures 3 to 7 As shown, in this embodiment, a control circuit component, a power supply component and a coil 101 are disposed in the bracket body 10, and a control component 40 for controlling the power on and off of the coil 101 is disposed on the bracket body 10. The control component 40, the power supply component and the coil 101 are all connected to the control circuit component. The control circuit component is preferably a circuit board 50, and the power supply component is preferably a battery 60. The battery 60 can be a rechargeable battery 60; the coil 101 is arranged on the periphery of the magnetic suction component 20. When the control component 40 is triggered, the coil 101 is energized to generate a magnetic field in the opposite direction to the magnetic field of the magnetic component 20, thereby weakening the magnetic field strength of the magnetic component 20, and further weakening the magnetic adsorption force of the magnetic component 20, so as to facilitate the removal of the mobile terminal from the magnetic bracket; when the control component 40 is deactivated, the coil 101 is powered off and no magnetic field is generated, and the magnetic component 20 restores its original magnetic field strength. The strong magnetic adsorption force generated by the magnetic component 20 can stably adsorb the mobile terminal, so that when the magnetic bracket is installed on a bicycle as a travel bracket, the mobile phone is not likely to fall off after the magnetic bracket is shaken.

[0041] In this embodiment, the control component 40 is a switch button; when the switch button is pressed, the coil 101 is energized to generate a magnetic field in the opposite direction to the magnetic field of the magnetic attraction component 20; when the switch button is released, the coil 101 is de-energized; of course, in other embodiments, the control component 40 may also adopt other structural methods, such as a touch button. When the finger continues to touch the touch button, the coil 101 is energized, and when the finger leaves the touch button, the coil 101 is de-energized.

[0042] like Figures 3 to 7 As shown, in this embodiment, a fixing frame 70 is provided inside the bracket body 10, the magnetic attraction member 20 is provided on a side of the fixing frame 70 close to the placement area, the coil 101 is wound on the fixing frame 70, and the control circuit component and the power supply component are located on a side of the fixing frame 70 away from the placement area. Specifically, the fixing frame 70 has a clearance cavity 71, which is provided on a side of the fixing frame 70 away from the placement area, and the control circuit component and the power supply component are located in the clearance cavity 71, so that the control circuit component and the power supply component can reduce the internal space occupied, thereby reducing the volume of the bracket body 10, so that the bracket body 10 can be made thinner.

[0043] like Figure 7 As shown, in this embodiment, the fixing frame 70 has a receiving groove 72 and a winding groove 73, the receiving groove 72 is arranged on the side of the fixing frame 70 close to the placement area, the winding groove 73 is arranged on the periphery of the receiving groove 72 and arranged on the peripheral side of the fixing frame 70, the magnetic suction member 20 is assembled in the receiving groove 72, and the coil 101 is wound in the winding groove 73, so that the coil 101 is wound around the periphery of the magnetic suction member 20, so that the coil 101 generates a magnetic field opposite to the magnetic field generated by the magnetic suction member 20 after power is turned on. An iron sheet 80 is installed in the receiving groove 72, and the magnetic suction member 20 is fixed on the side of the iron sheet 80 close to the placement area, so that the magnetic suction member 20 is stably adsorbed on the iron sheet 80.

[0044] like Figure 3 , Figure 5 and Figure 7 As shown, in this embodiment, an assembly cavity 11 is provided in the bracket body 10, the fixing frame 70, the control circuit component and the power supply component are all assembled in the assembly cavity 11, the support plate 30 covers the assembly cavity 11, and the bracket body 10 has a positioning step 12 on the side facing the support plate 30, the support plate 30 is positioned and bonded to the positioning step 12, the side of the magnetic suction component 20 close to the placement area is limited by the rear side wall of the support plate 30, and the outer peripheral side wall of the coil 101 is limited by the inner peripheral side wall of the assembly cavity 11.

[0045] like Figures 4 to 7As shown, in this embodiment, the side wall of the bracket body 10 has a mounting hole, and the control component 40 is assembled in the mounting hole with one end exposed outside the bracket body 10 and the other end extending into the bracket body 10. The bracket body 10 is provided with a makeshift groove 13 for the power line to pass through, and the makeshift groove 13 passes through the assembly cavity 11, so as to facilitate the threading of the control component 40 to realize the electrical connection between the control component 40 and the control circuit component.

[0046] like Figure 1 and Figure 2 As shown, in this embodiment, a locking member 90 for locking with an external structure is provided at the rear end of the bracket body 10. The locking member 90 is preferably a constraint belt with an adjustable locking space, so that the magnetic bracket can be locked to the external structure as a whole through the constraint belt. For example, when it is installed on a bicycle as a travel bracket, it is locked to the handlebar of the bicycle through the constraint belt.

[0047] In summary, the design focus of the utility model is that it mainly arranges a control circuit component, a power supply component and a coil in the bracket body, and arranges a control component on the bracket body, so that the control component, the power supply component and the coil are all connected to the control circuit component, and the control component is used to control the coil to be energized and de-energized. When the control component is triggered, the coil is energized to generate a magnetic field in the opposite direction to the magnetic field of the magnetic suction component, thereby weakening the magnetic field strength of the magnetic suction component, and then weakening the magnetic adsorption force of the magnetic suction component, so as to facilitate the removal of the mobile terminal from the magnetic suction bracket. When the triggering of the control component is cancelled, the coil is de-energized and no magnetic field is generated. The magnetic suction component restores the original magnetic field strength. The strong magnetic adsorption force generated by the magnetic suction component can stably adsorb the mobile terminal, so that when the magnetic suction bracket is installed on a bicycle as a travel bracket, the mobile phone is not easy to fall after the magnetic suction bracket is bumped. In this way, the magnetic field strength of the magnetic suction component can be adjusted by controlling the power on and off of the coil by the control component, so that the adsorption force can be adjusted to achieve the purpose of stably adsorbing the mobile terminal and conveniently removing the mobile terminal.
