The wireless charging assembly is applied to an electric vehicle, the electric vehicle comprises a vehicle body and a kickstand movably connected with the vehicle body, and the wireless charging assembly is characterized by further comprising a charging module and a receiving module; the charging module comprises a charging circuit and a transmitting coil; the receiving module comprises a receiving circuit and a receiving coil, and the receiving coil is arranged on the foot support; the charging circuit transmits electric energy to the receiving circuit through electromagnetic induction between the transmitting coil and the receiving coil. The electromagnetic induction distance between the transmitting coil and the receiving coil is smaller than 30 mm, and the size ratio of the transmitting coil to the receiving coil is 1.5-3. By optimizing the proportion of the transmitting coil and the receiving coil, higher energy transmission efficiency is achieved, when the size proportion of the transmitting coil and the receiving coil is within 1.5-3, mutual inductance is enhanced, and it can be guaranteed that the charging efficiency is 89% or above.

    本发明公开了一种无线充电组件,应用于电动车,所述电动车包括车体和与车体活动连接的脚撑,其特征在于,还包括充电模块和接收模块;所述充电模块包括充电电路和发射线圈;所述接收模块包括接收电路和接收线圈,所述接收线圈设在所述脚撑上;所述充电电路通过所述发射线圈和所述接收线圈之间的电磁感应将电能传输至所述接收电路;所述发射线圈和所述接收线圈之间的电磁感应间距小于30mm,所述发射线圈和所述接收线圈的尺寸比例为1.5‑3。本申请通过优化发射线圈和接收线圈的比例,实现了更高的能量传输效率,当发射线圈和接收线圈的尺寸比例在1.5至3内时,互感增强,能够保证充电效率在89%以上。
