The invention provides an electric vehicle hub motor wireless electric energy transmission system based on an unsprung coil structure, a power electronic module assembly of the transmission system is in signal connection with the receiving end of a magnetic coupling mechanism, and the receiving end of the magnetic coupling mechanism is connected to the lower end of the inner side of a hub motor through a connecting support; the magnetic coupling mechanism receiving end is installed below the magnetic coupling mechanism transmitting end, the power electronic module assembly is installed on the periphery of a transmission shaft of the hub motor, and the magnetic coupling mechanism transmitting end is embedded and installed on the surface of a road. The system solves the technical problems of limitation, low interoperability, narrow application scene and narrow application range of the design scheme of a magnetic coupling mechanism of a traditional electric vehicle wireless charging system, and adopts a planar magnetic coupling mechanism mounted below a suspension spring of an electric vehicle; the gap distance between the transmitting end and the receiving end of the magnetic coupling mechanism can be minimized, so that the wireless power transmission system provided by the invention has the advantages of high efficiency, good road adaptability and the like.

    本发明提出一种基于簧下线圈结构的电动汽车轮毂电机无线电能传输系统,该传输系统的电力电子模块总成与磁耦合机构接收端信号连接,磁耦合机构接收端通过连接支架连接于轮毂电机的内侧下端,磁耦合机构接收端安装于磁耦合机构发射端的下方,电力电子模块总成安装于轮毂电机的传动轴的外周,磁耦合机构发射端嵌入并安装于道路表面。解决了传统电动汽车无线充电系统磁耦合机构设计方案的局限性、低互操作性且应用场景和应用范围较窄的技术问题,本发明采用安装于电动汽车悬挂弹簧下方的平面式磁耦合机构,可以实现磁耦合机构发射端与接收端之间的间隙距离最小化,进而使得本发明所提出的无线电能传输系统具有高效率和良好的道路适应性等优势。
