The invention discloses a multi-degree-of-freedom multi-load wireless electric energy transmission device, which comprises a high-frequency inverter power supply, a cube-shaped transmitting coil, a receiving coil, a rectifying circuit, a resistive load and the like, wherein the cube-shaped transmitting coil is formed by winding a litz wire on twelve ferrites in series to form twelve magnetic dipoles, the magnetic field generated by the transmitting coil is uniformly distributed by changing the winding direction of each magnetic dipole, and the receiving coil is formed by winding a small cube-shaped ferrite coil. Compared with a traditional wireless electric energy transmission device, the multi-degree-of-freedom multi-load wireless electric energy transmission device solves the problem of limitation of wireless electric energy transmission space, magnetic dipoles are formed to enhance coupling between two coils, and power can be supplied to a plurality of loads at the same time so as to achieve multi-degree-of-freedom multi-load power output; and a solid foundation is laid for practicability and industrialization of the wireless power transmission system.

    本发明公开了一种能实现多自由度多负载无线电能传输装置,包括高频逆变电源、正方体型发射线圈、接收线圈、整流电路和电阻负载等;其中,正方体型发射线圈由利兹线绕制在十二个铁氧体串联,形成十二个磁耦极子,通过改变每个磁偶极子的绕制方向,使发射线圈产生的磁场均匀分布,而接收线圈由小型正方体型铁氧体线圈绕制而成。与传统无线电能传输装置相比,本发明解决了无线电能传输空间局限性问题,通过形成磁偶极子,增强两线圈之间的耦合,并同时能为多个负载供电,进而实现了多自由度多负载的功率输出;为无线输电系统的实用化工业化奠定坚实的基础。
