Title:
COIL MODULE, WIRELESS CHARGING TRANSMISSION APPARATUS, RECEIVING APPARATUS, SYSTEM, AND TERMINAL
Document Type and Number:
WIPO Patent Application WO/2020/029664
Kind Code:
A1
Abstract:
Disclosed by the present application are a coil module, wireless charging transmission apparatus, receiving apparatus, system, and terminal. The module comprises: a first planar coil winding and a second planar coil winding; the first wind of the first planar coil winding comprises a first outer side part and a first inner side part, and the end part of the first wind of the first planar coil winding comprises an end part of the first outer side part and an end part of the first inner side part; the first wind of the second planar coil winding comprises a second outer side part and a second inner side part, and the end part of the first wind of the second planar coil winding comprises an end part of the second outer side part and an end part of the second inner side part; the end part of the first outer side part is conductively connected to the end part of the second inner side part, and the end part of the second outer side part is conductively connected to the end part of the first inner side part. The present application effectively reduces the circulating current loss in the first planar coil winding and the second planar coil winding, and increases the wireless charging efficiency of the coil module.
