The invention discloses a double-U-shaped magnetic coupling mechanism for wireless charging of an unmanned aerial vehicle. The double-U-shaped magnetic coupling mechanism comprises a transmitting end arranged on a wireless charging platform and a receiving end arranged on a fuselage of the unmanned aerial vehicle, the transmitting end comprises two U-shaped magnetic cores which are arranged side by side, and transmitting end coils are wound on the U-shaped magnetic cores; and the receiving end comprises a receiving end coil wound on the unmanned aerial vehicle body, and the receiving end coil is coupled with the transmitting end coil above the transmitting end. According to the double-U-shaped magnetic coupling mechanism for wireless charging of the unmanned aerial vehicle, the receiving end of the double-U-shaped magnetic coupling mechanism is the rectangular hollow solenoid coil perpendicular to the magnetic core of the transmitting end, the received magnetic field area is larger than that of a planar coil, and more energy can be obtained; in addition, the shape of the receiving end coil is matched with the unmanned aerial vehicle body, the size of the unmanned aerial vehicle can be greatly reduced, the hollow design of the receiving end reduces the use amount of ferrite, the cost is reduced, the weight of the unmanned aerial vehicle is effectively reduced, and the flexibility and lightness of the unmanned aerial vehicle are greatly improved.
一种用于无人机无线充电的双U型磁耦合机构,包括设于无线充电平台上的发射端以及设于无人机机身上的接收端;所述发射端包括两个并排设置的U型磁芯,在U型磁芯上绕设有发射端线圈;所述接收端包括绕设于无人机机身上的接收端线圈,接收端线圈在发射端的上方与射端线圈相耦合。本发明提供一种用于无人机无线充电的双U型磁耦合机构,因其接收端为与发射端磁芯相垂直的矩形空心螺线管线圈,接收到磁场面积相对于平面线圈更大,可以获得更多的能量;此外,接收端线圈形状与无人机机身适配,能更大地降低无人机体积,接收端的空心设计减少了铁氧体的用量,从而降低了成本,有效地减轻无人机重量,大大提高了无人机灵活性和轻巧性。
