The invention discloses a magnetic coupling mechanism for anti-offset wireless charging of an unmanned aerial vehicle, which comprises transmitting coils, a receiving coil and a ferrite magnetic core, and is characterized in that the transmitting coils are two orthogonal coils and are respectively marked as a transmitting coil I and a transmitting coil II; the ferrite magnetic core is cross-shaped, the two orthogonal coils are wound on the ferrite magnetic core, and the receiving coil is embedded in the unmanned aerial vehicle; a magnetic field in a specific direction is generated right above the transmitting coil by adjusting the current of the transmitting coil, so that the magnetic field generated by the transmitting coil is right opposite to the receiving coil. According to the invention, the anti-offset performance is good, the current fluctuation amplitude of the receiving coil is small, and the efficiency reduction during single horizontal offset or composite offset is small.

    本发明公开了一种无人机抗偏移无线充电的磁耦合机构,包括发射线圈、接收线圈和铁氧体磁芯,发射线圈为两个正交线圈,分别记为发射线圈一和发射线圈二;铁氧体磁芯的形状为十字形,两个正交线圈缠绕在铁氧体磁芯上,接收线圈嵌入在无人机上;通过调节发射线圈电流的大小在发射线圈正上方产生特定方向的磁场,使发射线圈产生的磁场正对接收线圈。本发明不仅抗偏移性能良好,而且接收线圈电流波动幅度小,同时单一水平偏移或复合偏移时效率下降很小。
