The invention relates to the technical field of wireless charging, in particular to an omnibearing wireless charging device and method for an unmanned aerial vehicle. The device comprises a transmitting mechanism arranged on a wireless charging platform and a receiving mechanism arranged on an unmanned aerial vehicle. The transmitting mechanism comprises four arc-shaped solenoid coils, each arc-shaped solenoid coil is in a 1/4 circumference shape, and the four arc-shaped solenoid coils are evenly distributed on the same plane to form a complete circumference. The unmanned aerial vehicle comprises an undercarriage; the receiving mechanism comprises two receiving coils, and the two receiving coils are wound on two supporting legs of an undercarriage of the unmanned aerial vehicle respectively; the magnetic coupling mechanism provided by the invention hardly generates leakage magnetic flux at the fuselage of the unmanned aerial vehicle, the requirement on magnetic shielding can be reduced, and in addition, the magnetic coupling mechanism has good position deviation resistance and angle deviation resistance.

    本发明涉及无线充电技术领域,具体涉及一种无人机全方位无线充电装置及充电方法;所述装置包括:设置在无线充电平台的发射机构和设置在无人机上的接收机构;所述发射机构包括4个圆弧形螺线管线圈,每一个圆弧形螺线管线圈呈1/4圆周状,4个圆弧形螺线管线圈均匀分布在同一平面形成一个完整圆周;所述无人机包括起落架;所述接收机构包括两个接收线圈,两个接收线圈分别缠绕在无人机起落架的两个支脚上;本发明提出的磁耦合机构几乎不会在无人机机身处产生漏磁通,可以降低对磁屏蔽的要求,此外,本发明具有良好的抗位置偏移和抗角度偏移性能。
