Title:
WIRELESS CHARGING APPARATUS FOR ELECTRONIC DEVICES
Document Type and Number:
WIPO Patent Application WO/2022/124611
Kind Code:
A1
Abstract:
The present invention proposes a wireless charging apparatus for electronic devices, which, regardless of the position and direction in which an electronic device to be charged is placed, can uniformly charge the electronic device with high efficiency over the entire area. The wireless charging apparatus comprises a ferromagnetic or ferrimagnetic substance having a predetermined size and a plurality of coil bodies disposed in the ferromagnetic or ferrimagnetic substance. The coil bodies are arranged to be inclined from the left and right ends of the upper surface toward the center of the lower surface of the ferromagnetic or ferrimagnetic substance, or arranged to be inclined from the upper surface toward the lower surface of the ferromagnetic or ferrimagnetic substance in the same direction and in parallel with each other.
