The invention provides a conical wireless charging coil with a novel winding mode, and belongs to the technical field of wireless charging equipment. The problem that the transmission efficiency of a wireless magnetic coupling resonance type electric energy transmission system is low due to the fact that an existing wireless charging receiving and transmitting coil is large in deviation angle during charging is mainly solved. The wireless charging coil comprises a conical transmitting coil and a conical receiving coil which are symmetrical, and is of a three-dimensional spiral conical structure. When the coil is used for wireless charging, the transmitting coil and the receiving coil can automatically correct the deviation angle, so that the magnetic field coupling degree is improved, and the electric energy transmission efficiency is improved.
本发明专利提供了一种新型绕线方式的锥型无线充电线圈,属于无线充电设备的技术领域。主要解决现有无线充电收发线圈充电时偏移角度大,进而导致无线磁耦合共振式电能传输系统的传输效率低的问题。该无线充电线圈包括对称的锥型发射线圈和锥型接收线圈两部分,为立体螺线锥型结构。本线圈用于无线充电时,发射线圈和接收线圈可以自行矫正偏移角度,从而提高磁场耦合程度,提高了电能传输的效率。
