Problems solved by technology

[0004] However, the suction of the wireless charging energy transmitter is usually not strong, and the car will cause the mobile phone to wait for the charging device to fall
The magnet is a magnetized magnet, and its own suction is determined by the material and size. It is limited by the size of the mobile phone and the material of mass production, so the suction cannot be further improved.

Abstract

The invention provides a strong-attraction-force magnetic-attraction wireless charging device which comprises a shell, and a power input module, a wireless charging module, a voltage reduction module, a wireless charging controller and an electromagnet which are arranged on the shell. Wherein the power input module is used for supplying power to the wireless charging module and the voltage reduction module. And the wireless charging module is used for wirelessly charging the to-be-charged device. The voltage drop module is used for converting the input voltage into the power supply voltage of the electromagnet. The wireless charging controller is used for controlling whether the power input module supplies power to the wireless charging module and the voltage reduction module or not and controlling the power supply voltage. An electromagnet is adopted to provide magnetic attraction force for a to-be-charged device, and strong attraction force and controllable attraction force are achieved by controlling the current of the electromagnet. The invention further provides a magnetic attraction wireless charging control method applied to the strong-attraction-force magnetic attraction wireless charging equipment.

Description

technical field [0001] The invention belongs to the technical field of wireless charging, and in particular relates to a strong suction magnetic suction wireless charging device and a magnetic suction wireless charging control method. Background technique [0002] There are two ways to fix the mobile phone of the car wireless charger, magnetic fixation and clip fixation. The former relies on magnet suction to fix the phone, while the latter relies on clips to clamp the phone to ensure that the phone does not fall. The advantage of the former is that it is convenient, that is, it can be placed and sucked, the coil is aligned, and the charging efficiency is high; the disadvantage is that the suction is small; the advantage of the latter is that it is tightly clamped, but it will cause a gap between the mobile phone and wireless charging, resulting in low charging efficiency. [0003] The existing magnetic wireless charging products all use NdFeB magnets. There is a circle of...
