5. The vehicle wireless charging ground lock structure according to claim 1, wherein: the wireless transmitting coil assembly comprises an upper cover, a transmitting coil winding and a protecting ring, wherein the transmitting coil winding is arranged in a spiral groove at the bottom of the upper cover, and the protecting ring seals the transmitting coil winding in the spiral groove.
6. The vehicle wireless charging ground lock structure according to claim 5, wherein: the top of the radiator is provided with a groove, the ferrite is arranged in the groove, and the protection ring is in contact with the ferrite.
7. A wireless charging method for an automobile, which is charged by using the ground lock structure as claimed in claim 1, comprising the steps of:
step S1: the method comprises the steps of opening an automobile to be stopped to the vicinity of a specified parking space, adjusting a ground lock bracket from a lifting state to a horizontal state through a controller, and then parking the automobile in the parking space;
step S2: judging the stored electric quantity of the battery, and determining whether the battery needs to be charged or not;
step S3: if the battery needs to be charged, the controller wakes up a control circuit of the wireless transmitting coil assembly, starts an infrared sensing receiver at the center of the wireless transmitting coil assembly, and receives an infrared signal sent by an infrared sensor arranged at the center of a wireless receiving coil below the automobile chassis;
step S4: acquiring position coordinate values of a wireless transmitting coil assembly and a receiving coil of an automobile chassis;
step S5: the telescopic lengths of the first electric push rod and the second electric push rod are adjusted through the controller so as to move the positions of the transmitting coils in the X and Y directions, and the center of the transmitting coils is coaxial with the center of the receiving coil arranged on the chassis of the automobile;
step S6: when the center of the transmitting coil is coaxial with the center of the receiving coil of the automobile chassis, a power supply of the transmitting coil is connected through the controller, the transmitting coil starts to emit high-frequency electromagnetic waves, and the battery is charged after induction of the receiving coil of the automobile chassis;
step S7: when the battery is full of electricity, the power supply of the wireless transmitting coil is cut off, so that the control circuit of the transmitting coil enters a sleep state, and the charging work is stopped;
step S8: after the automobile leaves the parking space, the ground lock bracket is lifted by the controller to lock the parking space.
