The embodiment of the invention provides a wireless charging module and a processing method thereof and a wireless charging device of a vehicle. The wireless charging module comprises a coil and a shielding component, wherein the shielding component is used for limiting magnetic induction lines of the coil inside the wireless charging module; the shielding component comprises an outer shielding part; the outer shielding part is arranged on the outer side of the coil; the outer shielding part is used for reducing the leakage flux of the wireless charging module. After the wireless charging module is equipped with the outer shielding part, even if parking offset causes incapable alignment of a transmitting coil and a receiving coil, the leakage flux of the wireless charging device can be also reduced through the outer shielding part, so that the coupling coefficient between a transmitting module and a receiving module is increased, the transmission efficiency between the transmitting module and the receiving module is improved, the risk of the leakage flux forming an eddy current in external metal is reduced, and the charging efficiency is improved; in addition, when multiple inner shielding parts and/or multiple outer shielding parts are added, the cost can be saved. Through arrangement of the outer shielding part, a requirement of the wireless charging device on the parking accuracy is also lowered, so that achievement of more free wireless charging is facilitated.
