The patent document with publication number of CN108004975A discloses a wireless charging ground lock structure of an automobile, in the scheme, although a radiator is arranged below a wireless transmitting coil assembly, the radiator is a traditional radiating fin radiator which is distributed in parallel, because the wireless transmitting coil assembly is arranged inside the ground lock structure, the volume is extremely limited, the radiating space below the radiator is extremely limited (the radiator is also arranged below the wireless transmitting coil assembly, otherwise, the wireless charging process is easily influenced greatly, but the radiator is limited by the structure of the ground lock and the height of an automobile chassis, and the radiating efficiency is not feasible by increasing the radiating space below the radiator), meanwhile, in the wireless charging process, the wireless radiating coil and the radiator are arranged in a relatively closed space formed by the ground lock bracket and the ground lock shield, and the heat cannot be timely and efficiently radiated. In addition, even if the heat can be emitted, the main emission direction is mainly concentrated around and above the ground lock, so that the temperature of the surrounding environment of the ground lock is easily increased, and cooler air cannot enter the ground lock, so that the heat dissipation efficiency is low, and the high-temperature environment can also have adverse effects on the chassis of the automobile. Therefore, how to improve the heat dissipation scheme of the ground lock structure integrated with the wireless charging function to improve the heat dissipation efficiency is a current urgent problem to be solved.

2. In the wireless charging process, the ground lock bracket formed by the hollow brackets is in a state of falling to the base, and at the moment, the first hollow bracket, the second hollow bracket, the horizontal bracket, the base and the cover plate form an inner space which contains the wireless transmitting coil component, the radiator and other components, the inner space plays a sealing role and is used for guiding colder air from one side of the first hollow bracket to the second hollow bracket through the inner space so as to form radiating airflow, and heat can be efficiently guided and radiated to the outside.
