WIRELESS CHARGING DEVICE AND SYSTEM WITH SUPPRESSED ELECTROMAGNETIC WAVE DIVERGENCE AND ENHANCED CHARGING EFFICIENCY
First Claim
1. A wireless charging device for wirelessly charging at least one power-receiving device, the wireless charging device comprising:
- a casing comprising a main body, wherein the main body has an accommodation space and an entrance, and the at least one power-receiving device is accommodated within the accommodation space;
at least one transmitter coil assembly disposed within the main body, and emitting an electromagnetic wave with at least one specified frequency for wirelessly charging the at least one power-receiving device, wherein each transmitter coil assembly comprises at least one antenna for receiving an AC signal so as to emit the electromagnetic wave; and
a shielding structure attached on an outer surface of the main body or disposed within the main body, wherein the shielding structure at least shields the antenna of the transmitter coil assembly so as to block divergence of the electromagnetic wave.

Abstract
A wireless charging device includes a casing, a transmitter coil assembly and a shielding structure. The casing includes a main body with an accommodation space and an entrance. At least one power-receiving device is accommodated within the accommodation space. The transmitter coil assembly is disposed within the main body, and emits an electromagnetic wave with at least one specified frequency for wirelessly charging the at least one power-receiving device. Each transmitter coil assembly includes at least one antenna for receiving an AC signal so as to emit the electromagnetic wave. The shielding structure is attached on an outer surface of the main body or disposed within the main body. The shielding structure at least shields the antenna of the transmitter coil assembly so as to block divergence of the electromagnetic wave.
