Wireless Charging Receiving Device and Wireless Charging System Using the Same

摘要

A wireless charging receiving device includes a body, a metal housing, a receiving coil, and a power storage device. The metal housing is coupled to the body to form an accommodating space. The metal housing includes an aperture and at least one slit. The slit interconnects the aperture and the edge of the metal housing. The receiving coil is disposed between the metal housing and the body. The receiving coil defines a through hole by a looped configuration, and the through hole overlaps at least part of the aperture of the metal housing. The power storage device is disposed within the accommodating space and electrically connected to the receiving coil. Electromagnetic waves are able to pass through the aperture of the metal housing and are magnetically coupled to the receiving coil, such that the receiving coil transfers the energy of the electromagnetic waves to the power storage device.
