Abstract
A wireless charging receiving apparatus of a mobile terminal. The wireless charging receiving apparatus is configured to be disposed inside the mobile terminal and close to a metal rear housing (3) of the mobile terminal, and includes two interconnected coils (701,702). The two coils (701,702) are located in a same plane and are connected in series, and winding directions of the two coils (701,702) are opposite, so that directions of magnetic fluxes generated by the two coils (701,702) on the metal rear housing (3) are opposite, thereby resolving a problem of an eddy current on the metal rear housing of the mobile terminal such as a smartphone including a wireless charging system, and reducing a temperature of a metal body and reducing an energy loss without forming a hole or a seam on the metal rear housing.
