Abstract

The present application discloses a coil winding and belongs to the technical field of wireless charging. The coil winding includes an insulating layer; a first partial coil on one side of the insulating layer; and a second partial coil on the other side of the insulating layer. The first partial coil comprises a first wire section. The second partial coil comprises a second wire section. The first wire section and the second wire section each have N slots. The first wire section is divided into N+1 first sub-wires by its N slots. The second wire section is divided into N+1 second sub-wires by its N slots. The N+1 first sub-wires and the N+1 second sub-wires are electrically connected to each other one to one to form N+1 pairs of sub-wires. At least one cross structure is formed in the N+1 pairs of sub-wires. The ring current loss in the coil winding can be reduced and the wireless charging efficiency can be improved. In addition, the present application also discloses a corresponding coil module, a wireless charging transmitting device, a wireless charging receiving device, a wireless charging system, and a terminal.

Description

technical field [0001] The present application relates to the technical field of wireless charging, in particular to a coil winding, a coil module, a transmitting device, a receiving device, a system and a terminal. Background technique [0002] Currently, it is becoming more and more popular to use wireless charging technology to charge electronic devices. Devices that implement wireless charging technology are called wireless chargers. In a specific implementation, the wireless charger is provided with a transmitting coil, and the electronic device is provided with a receiving coil. The alternating current carried by the transmitting coil in the wireless charger generates a magnetic field, and the receiving coil in the electronic device generates a voltage through magnetic coupling, thereby Realize the charging of electronic equipment. [0003] Since wireless charging is based on the magnetic coupling between the transmitting coil and the receiving coil for energy transm...
