when the battery module vibrates up and down, the battery module can extrude and deform the elastic sheet 20, and a certain damping effect is achieved on the battery module through the deformed elastic sheet 20, and the bottom end of the battery module can be communicated with the outside through the arranged heat dissipation holes 21 and the through grooves 22, so that the heat dissipation effect of the bottom end of the battery module is improved, when the water quantity at the bottom end of the box body 1 is large in rainy days, a part of accumulated water can flow into the through grooves 22 and then is in contact with the blocking blocks 24, the blocking blocks 24 expand and deform in the presence of water and block the through grooves 22, and therefore the condition that a large amount of external accumulated water flows into the installation cavity 4 and influences the service life of the battery module can be reduced; when the elastic sheet 20 is deformed under pressure, the two ends of the elastic sheet 20 can extrude the air bag 25 at the moment, so that the gas in the air bag 25 flows into the elastic body 5 from the air inlet pipe 26 and the airflow one-way circulation assembly 27, and meanwhile, when the air bag 25 is reset, the air bag 25 can drive the one-way valve 28 to work, and suck the gas with low external temperature through the air inlet groove, so that the air bag 25 can achieve the ventilation effect on the gas in the elastic body 5, and the heat dissipation effect of the elastic body 5 on the battery module is further improved; when external accumulated water flows into two sides of the heat dissipation hole 21 from the through groove 22, the guide plate 29 and the arc-shaped plate 30 arranged at the moment can stop the accumulated water, the accumulated water is reduced to flow to the position of the box body 1 corresponding to the protruding area of the elastic sheet 20 and generate accumulation, and meanwhile, when the elastic sheet 20 deforms, the elastic unit 31 can always press the arc-shaped plate 30 on the bottom surface of the box body 1, so that the work of the arc-shaped plate 30 can be stably carried out; the breather pipe 32 that sets up can support intercommunication groove 14, reduces fixture block 13 and card chamber 12 extrusion fit, leads to intercommunication groove 14 internal contraction and influences the condition that the gas flows, simultaneously through the position that sets up intercommunication groove 14 and breather pipe 32, when preventing fixture block 13 from pressing in from the accent of card chamber 12, the condition that fixture block 13 is difficult to press in is led to in card chamber 12 mouth and rigid breather pipe 32 contact.
