The invention discloses an unmanned aerial vehicle wireless charging transmitter, receiver and anti-offset magnetic coupler, the unmanned aerial vehicle wireless charging transmitter comprises a wireless charging transmitter and a wireless charging receiver, the wireless charging transmitter comprises a transmitting coil and a ferrite array, the transmitting coil is arranged on the ferrite array, the ferrite array comprises a central ferrite and a plurality of ferrite rods, and the ferrite rods are arranged on the central ferrite. A plurality of ferrite rods are radially distributed around the central ferrite, the ferrite array covers the whole area of the transmitting coil, a gap exists between the wireless charging receiver and the wireless charging transmitter, the wireless charging receiver and the wireless charging transmitter are arranged at intervals, and the wireless charging receiver comprises a receiving coil. By arranging the ferrite array, the area of the transmitting coil is larger than that of the receiving coil, the area perpendicular to the magnetic induction line direction is increased, the receiving coil can be covered, the magnetic flux is not affected, the requirements for positioning and alignment in the charging process are reduced, the wireless power transmission efficiency and the reliability of the charging system are improved, and the operation cost of the unmanned aerial vehicle is reduced.

    本发明公开了一种无人机无线充电发射器、接收器及抗偏移磁耦合器,包括无线充电发射器和无线充电接收器,无线充电发射器包括发射线圈和铁氧体阵列,发射线圈设置在铁氧体阵列上,铁氧体阵列包括中心铁氧体和多根铁氧体棒,多根铁氧体棒呈放射状分布在中心铁氧体周围,所述铁氧体阵列覆盖发射线圈的全部区域,无线充电接收器与所述无线充电发射器之间存在间隙并间隔设置,所述无线充电接收器包括接收线圈。通过设置铁氧体阵列,使发射线圈的面积大于接收线圈的面积,垂直于磁感线方向的面积增大,能够覆盖接收线圈,不影响磁通量,降低了充电过程中对定位和对准的要求,提高了无线输电效率和充电系统的可靠性,降低了无人机的运行成本。
