[0037] The working principle of the present invention is: when in use, a person skilled in the art fixes the support plate 110 to the third slot 120 on the top of the battery compartment 100 with a bolt, and then screws 131 are installed in the screw holes 130 at the bottom of the battery compartment 100 through threaded connection, and the first collapse energy absorbing block 210 is evenly installed on the inner wall of the energy absorbing plate 200, and then the second collapse energy absorbing block 220 is installed obliquely between the two first collapse energy absorbing blocks 210, and then the countersunk hole 230 in the energy absorbing plate 200 is sleeved and installed on the outer wall of the bottom end of the screw 131, and then the energy absorbing plate 200 is inserted into the countersunk hole 230 through the nut 132, and the nut 132 is threadedly connected to the outer wall of the bottom end of the screw 131 through an inner hexagonal wrench, so that the energy absorbing plate 200 is fixed to the bottom outer wall of the battery compartment 100. , then the temperature sensors 170 are fixedly installed one by one inside the circular grooves 160, the electric heater 181 is plugged into the two first slots 150 at the bottom of the battery compartment 100, and the partition plate 180 is plugged into the second slot 151, so that the partition plate 180 is electrically connected to the electric heater 181, and then the electric heater 181 is connected to the battery and the electromagnetic switch to form a circuit, and then the battery pack is connected in parallel, and the battery pack is installed inside the battery compartment 100. The temperature sensor 170 monitors the temperature of the bottom of the battery pack, and the batteries are evenly placed on both sides of the partition plate 180. During the use of the new energy vehicle, the temperature of the battery is monitored in real time by the temperature sensor 170, and the air inlet and outlet adjustment rollers are rotated through the shaft 334. The servo motor 340 is rotatably connected to the inner wall of the air inlet and outlet 320, and the servo motor 340 is installed on the inner wall of the battery compartment 100, so that the servo motor 340 and the outer wall of the rotating shaft 334 are meshed and connected through the gear 341, and the servo motor 340 is electrically connected to the battery. When the temperature sensor 170 detects that the battery temperature is too high, the servo motor 340 is turned on to drive the rotating shaft 334 to rotate, thereby driving the air inlet and outlet adjustment roller to rotate and adjust the position of the ventilation slot 333, so that the ventilation slot 333 forms an opening to the battery compartment 100 and the environment. During the driving of the new energy vehicle, the air flow in the environment passes through the first air supply block 331 and the second air supply block 332. The ventilation slot 333 enters the interior of the battery compartment 100 and the protective cover 300, so that under the action of the two air inlet and outlet adjustment rollers, the interior of the battery compartment 100 is ventilated, thereby dissipating heat from the battery and reducing the temperature of the battery to within the rated operating temperature range. When the temperature is lower than the rated temperature, the servo motor 340 is turned on to drive the air inlet and outlet adjustment rollers to rotate, so that the openings at both ends of the ventilation slot 333 enter the inside of the battery compartment 100, preventing air from flowing through the ventilation slot 333, thereby keeping the interior of the battery compartment 100 warm. When the temperature is lower in winter, the electric heater 181 is energized to energize the resistance wire inside the electric heater 181.The electric heating plate 181 can heat the partition plate 180, so that the partition plate 180 can heat the surrounding environment of the battery, increase the temperature inside the battery compartment 100, and make the temperature of the battery rise to the rated operating temperature.
