WIRELESS CHARGING DEVICE AND SYSTEM WITH SUPPRESSED ELECTROMAGNETIC WAVE DIVERGENCE AND ENHANCED CHARGING EFFICIENCY

摘要

The present invention provides a wireless charging device to suppress the emission of an electromagnetic wave and to improve charging efficiency. The wireless charging device comprises: a case; a transmitter coil assembly; and a shielding structure. The case comprises a main body including an accommodating space and an inlet. At least one power receiving device is accommodated in the accommodating space. The transmitter coil assembly is disposed in the main body and emits an electromagnetic wave having at least one specific frequency so as to wirelessly charge at least one power receiving device. Each of the transmitter coil assemblies includes at least one antenna to receive an AC signal for emitting the electromagnetic wave. The shielding structure is attached to the outer surface of the main body or disposed in the main body. The shielding structure can shield at least the antenna of the transmitter coil assembly to prevent the electromagnetic wave from being emitted.;COPYRIGHT KIPO 2016
