Abstract

The application discloses a coil module, a wireless charging transmitting device, a wireless charging receiving device, a wireless charging system, and a terminal. The coil module includes a first planar coil winding and a second planar coil winding. The first turn of coil of the first planar coil winding include a first outer portion and a first inner portion, and the end portion of the first turn of coil of the first planar coil winding includes the end portion of the first outer portion and the end portion of the first inner portion. The first turn of coil of the second planar coil windingincludes a second outer portion and a second inner portion, and the end portion of the first turn of coil of the second planar coil winding includes the end portion of the second outer portion and theend portion of the second inner portion. The end portion of the first outer portion and the end portion of the second inner portion are electrically connected. The end portion of the second outer portion and the end portion of the first inner portion are electrically connected. The coil module can reduce the circulating current loss in the first planar coil winding and the second planar coil winding, and is improved in wireless charging efficiency.

Description

[0001] This application claims the priority of the Chinese patent application with the application number 201810881202.X and the title of the invention "coil module, wireless charging transmitting device, receiving device, system and terminal" submitted on August 04, 2018, the entire content of which Incorporated in this application by reference. technical field [0002] The present application relates to the technical field of wireless charging, in particular to a coil module, a wireless charging transmitting device, a receiving device, a system and a terminal.
