A connecting piece 12 is fixedly installed on the left end of the mounting ring 13, and a rubber protective cap 2 is fixedly installed on the left end of the connecting piece 12. The rubber protective cap 2 is arranged on the left side of the vehicle charger body 1, and the diameter of the rubber protective cap 2 is equal to the diameter of the mounting ring 13; a containing groove 8 is provided at the inner end of the rubber protective cap 2, and a metal spring 10 is provided at the lower end of the rubber protective cap 2. Hollow grooves 9 are equidistantly installed at the inner end of the metal spring 10, which is convenient for protecting the connection port 4 to prevent dust and water stains from accidentally entering, and at the same time has a buffering and anti-pressure effect;

[0028] The retaining ring 3 is fitted on the inner end of the mounting ring 13, and the inner surface of the retaining ring 3 is threadedly connected to the outer end of the threaded sheet 6. The outer end of the retaining ring 3 is provided with vertical grooves 11 at equal angles. The retaining ring 3 is arranged on the outer side of the alloy heat dissipation net 5, and the alloy heat dissipation net 5 is located on the outer side of the connection port 4. The retaining ring 3 can be adjusted in height on the outer side of the alloy heat dissipation net 5 through the threaded sheet 6. The installation of the alloy heat dissipation net 5 can play a role in heat dissipation. When heat dissipation is not required, the retaining ring 3 can be used for enclosure.

[0029] Specific working principle:

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when the vehicle charger with a protective structure is used, the mounting end 7 at the lower end of the vehicle charger body 1 is inserted into a dedicated socket in the vehicle for use. When charging, the rubber protective cap 2 is opened outward, and the rubber protective cap 2 is connected to the mounting ring 13 by the connecting piece 12 after being opened. Then, whether heat dissipation is required is selected according to the ambient temperature. When the vehicle charger body 1 needs to be cooled, the retaining ring 3 is rotated downward, and the inner ring of the retaining ring 3 is threaded. The retaining ring 3 is threadedly rotated downward at the outer end of the threaded piece 6 to make the alloy heat dissipation net 5 The alloy heat dissipation net 5 has a good heat dissipation effect, and then the data cable is inserted into the inside of the connection port 4 for use.
