The invention belongs to the technical field of wireless power transmission, and particularly relates to a coupling mechanism for improving the anti-offset capability of the wireless charging system of an unmanned aerial vehicle. The coupling mechanism comprises a transmitting mechanism and a receiving mechanism; a receiving coil of the receiving mechanism is located above a transmitting coil of the transmitting mechanism, and the receiving coil and the transmitting coil are coupled with each other; the transmitting coil is a concentric-square-shaped planar coil formed by winding a wire in a plane, and an unwound area is reserved in the middle of the concentric-square-shaped planar coil; and the receiving coil is a spiral tubular coil formed by winding a wire. According to the invention, the transmitting coil adopts the concentric-square-shaped planar coil, and the receiving coil adopts the spiral tubular coil; the primary side magnetic field generated by the primary and secondary sidestructure is relatively uniform; when the receiving coil deviates, the mutual inductance fluctuation of the primary coil and the secondary coil is relatively small; the output power of the wireless charging system is relatively stable; and the anti-deviation capability of the wireless charging system is improved.

    本发明属于无线电能传输技术领域,具体涉及一种提升无人机无线充电系统抗偏移能力的耦合机构,所述耦合机构包括包括发射机构和接收机构,所述接收机构的接收线圈位于所述发射机构的发射线圈上方,所述接收线圈和发射线圈相互耦合;所述发射线圈是采用导线在平面内绕制而成的回形平面线圈,所述回形平面线圈中部留有未绕制区;所述接收线圈是采用导线绕制而成的螺旋管状线圈。本发明的发射线圈采用回形平面线圈,接收线圈采用螺旋管状线圈,这样的原副边结构,产生的原边磁场较为均匀,当接收线圈发生偏移时原副边线圈的互感波动较小,无线充电系统的输出功率较平稳,提高了无线充电系统的抗偏移能力。
