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.
