COIL, WIRELESS CHARGING TRANSMITTING DEVICE, WIRELESS CHARGING RECEIVING DEVICE, AND MOBILE TERMINAL

WIPO Patent Application WO/2023/279639

A1

The present invention relates to the technical field of electric power. Disclosed are a coil, a wireless charging transmitting device, a wireless charging receiving device, and a mobile terminal. Aiming at the prior art problem of a low coil quality factor due to a limited space and area, the present invention provides a coil, a wireless charging transmitting device, a wireless charging receiving device, and a mobile terminal. In the present solution, in view of the situation that the quality factor of the coil is low due to the limited space and area, the coil structure design is optimized on the basis of the original process. The provision of filling threads at intervals between wires effectively minimizes AC loss of the entire coil, reduces the proximity effect and skin effect, and ensures the quality factor of the coil, thereby achieving a higher quality factor with a certain area and volume, and achieving higher charging efficiency.
