[0032] The ventilation and cooling component 3 includes a connecting cover 31, a fan 32 and a pipe 33. The connecting cover 31 is fixedly installed inside the protective box 2. The fan 32 is fixedly installed on one side of the connecting cover 31. The output end of the fan 32 is fixedly connected to the pipe 33. One end of the pipe 33 passes through the car body 1 and connects with the air outlet plate 4.

[0033] A through groove 10 is provided on one side of the car body 1, and a filter screen is installed at the end of the through groove 10;

[0034] When the fan 32 is started, the external air passes through the filter plate 6 for filtration. After filtration, the air enters the connecting cover 31 and then enters the air outlet plate 4 through the pipe 33 and is discharged into the car body 1. The air inside the car body 1 is discharged through the channel 10. The filter screen prevents dust in the external air from entering the car body 1 through the channel 10, thereby ventilating and cooling the car body 1.
