The unmanned aerial vehicle wireless charging magnetic coupling mechanism comprises planar coils which are located on a charging base, transversely and adjacently arranged in groups and used for generating variable magnetic fields, and the directions of the magnetic fields generated by every two adjacent planar coils at the same moment are opposite; the unmanned aerial vehicle further comprises a receiving end arranged on the unmanned aerial vehicle. The receiving end comprises a plurality of columnar spiral coils used for generating induction current through the variable magnetic field. When the unmanned aerial vehicle is charged, the columnar spiral coil is transversely located between the planar coils in groups or above the planar coils, so that magnetic fields generated by the adjacent planar coils in groups form a loop through the columnar spiral coil, and electromagnetic coupling of the unmanned aerial vehicle charging system is greatly enhanced; the problem of low wireless charging efficiency of the unmanned aerial vehicle in the prior art is solved. In addition, the unmanned aerial vehicle rotates by 90 degrees along a shaft perpendicular to the charging platform, electric energy can still be supplemented when the unmanned aerial vehicle rotates by 180 degrees, and the charging convenience of the unmanned aerial vehicle is improved.
本发明涉及一种无人机无线充电磁耦合机构,包括位于充电底座、成组横向相邻设置的用于产生变化磁场的平面线圈,同一时刻相邻两个平面线圈产生的磁场方向相反;还包括设置于无人机上的接收端,所述接收端包括若干个用于通过所述变化磁场产生感应电流柱状螺旋线圈;本发明使得无人机在充电时,柱状螺旋线圈横向位于成组的平面线圈之间或平面线圈之间的上方,使得成组的相邻设置的平面线圈所产生的磁场通过柱状螺旋线圈形成回路,极大地增强了无人机充电系统的电磁耦合,解决了现有技术中无人机无线充电效率较低的问题;此外,无人机沿垂直于充电平台的轴旋转90°、180°时依旧可以补充电能,提高了无人机充电的便捷性。
