namely, the continuous flow of air in the loop can be realized by the rotation of the packing auger 8 in the running process of the vehicle body 1, and the temperature of the air is monitored in real time by the temperature sensor, so that the air is heated or cooled according to the air temperature, and the battery pack 29 is correspondingly heated or cooled; the overall flow chart, as shown in fig. 8, ensures normal and efficient operation of the battery pack 29; meanwhile, when the vehicle body 1 does not run or wind in the running process cannot drive the rotating shaft 6 to rotate, the plug hole 27 of the connecting shaft 22 is in plug-in fit with the corresponding plug 28 of the cross shaft 6 through contraction of the electric push rod 23, after the plug hole 27 is in plug-in fit with the plug 28, relative rotation does not occur between the cross shaft 10 and the connecting shaft 22, the telescopic shaft 21 and the connecting shaft 22 are driven to rotate through the power module 20, the rotating shaft 6 is driven to rotate, and air in the cavity 5 is driven to move from the rear side to the front side through rotation of the auger 8.
Of course, the temperature adjusting duct 30 may also be a square duct, that is, the battery pack 29 is wrapped inside the temperature adjusting duct 30 (not shown in the figure), so that the temperature adjusting duct 30 wraps the corresponding battery pack 29 to more effectively ensure the heat transfer between the battery pack 29 and the temperature adjusting duct 30, and thus the temperature adjusting effect of the temperature adjusting duct 30 on the battery pack 29 is better.
