Rotating magnet array magnetic attraction device and mobile power supply, adapter and mobile terminal

Abstract

The application discloses a rotating magnet array magnetic attraction device, a mobile power supply, an adapter and a mobile terminal, and relates to the technical field of wireless charging. The rotating magnet array magnetic attraction device comprises a first magnetic attraction assembly, and a plurality of rotating magnets are arranged in the first magnetic attraction assembly and can rotate independently. When the rotating magnet array magnetic attraction device is close to a secondary electronic device, each rotating magnet can rotate around the rotating axis thereof under the action of an external magnetic field, so that the magnetic pole direction of the rotating magnet is adjusted to be opposite to the magnetic pole direction of a corresponding position of a secondary magnetic attraction element of the external electronic device. Through the passive adaptive polarity adjustment, it is ensured that no matter how the magnetic pole arrangement of the external device is, the rotating magnet array magnetic attraction device can form stable magnetic attraction with the external device. The rotating magnet array magnetic attraction device overcomes the problem that magnetic repulsion is generated between electronic devices due to the fixed and same magnetic pole arrangement, so that effective adsorption and alignment cannot be realized.
