Abstract

The application discloses a coil winding, which belongs to the technical field of wireless charging. The coil winding includes: an insulating layer, a first partial coil located on one side of the insulating layer, and a second partial coil located on the other side of the insulating layer. The first part of the coil includes a first section of wire, the second part of the coil includes a second section of wire, both the first section of wire and the second section of wire have N slots, and the first section of wire is divided into N+ by the N slots it has. 1 strand of the first sub-conductor, the second segment of the conductor is divided into N+1 strands of the second sub-conductor by the N slots it has; N+1 strands of the first sub-conductor and N+1 strands of the second sub-conductor are one-to-one The electrical connection forms N+1 pairs of sub-conductors, and at least one cross structure is formed in the N+1 pairs of sub-conductors. The application can reduce the circulation loss in the coil winding and improve the efficiency of wireless charging. 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...
