WIPO Patent Application WO/2020/238192

Kind Code:

A1

Abstract:

Disclosed in the present application is a coil winding, which relates to the technical field of wireless charging. The coil winding comprises: an insulative layer, a first partial coil located at one side of the insulative layer, and a second partial coil located at the other side of the insulative layer. The first partial coil comprises a first wire segment, the second partial coil comprises a second wire segment, the first wire segment and the second wire segment are both provided with N cut-out slots, the first wire segment is divided by the N cut-out slots thereof into N+1 first sub-wires, and the second wire segment is divided by the N cut-out slots thereof into N+1 second sub-wires; the N+1 first sub-wires and the N+1 second sub-wires are electrically connected one-to-one so as to form N+1 pairs of sub-wires, and at least one intersecting structure is formed in the N+1 pairs of sub-wires. The present application can reduce current circulation loss in the coil winding and increase wireless charging efficiency. In addition, the present application further comprises a corresponding coil module, wireless charging transmitting device, wireless receiving device, wireless charging system, and terminal.
