Abstract

The invention provides a wireless charging magnetic positioning structure, a wireless charging module and a wireless charger. The wireless charging magnetic positioning structure comprises a first magnet and a magnetic conductive sheet; and the magnetic conductive sheet is attached to one side of the first magnet. By introducing the magnetic conductive sheet into the magnetic positioning structure and attaching the magnetic conductive sheet to the positioning magnet, magnetic lines can be focused, the magnetic path length of the magnetic lines generated by the positioning magnet can be shortened, the magnetic leakage of the positioning magnet can be reduced, and the magnetic field intensity of the magnetic positioning structure can be increased, so that accurate positioning of wireless charging coils at a transmitting end and a receiving end can be further realized, the coil coupling coefficient is effectively improved, and the charging efficiency is improved.
