[0036] The heat dissipation mechanism 7 further comprises a limiting frame 25 fixedly installed on the top end outer wall of the lifting box 2, the bottom end of the fixed box 1 is fixedly connected with a supporting frame 26, the bottom end of the lifting box 2 is provided with a storage groove 27, the storage groove 27 is inserted with a filter screen 28, the storage groove 27 is inserted with a mounting rod 38, the mounting rod 38 is fixedly connected with the bottom surface of the lifting box 2 through bolts, the sidewall of the lifting box 2 is provided with a first communication groove 29 and a second communication groove 30 respectively communicating with the two sides of the storage groove 27, the first communication groove 29 is located on the side close to the battery pack 39, the sidewall of the supporting frame 26 is fixedly connected with a plurality of cleaning teeth 31, and the sidewall of the cleaning tooth 31 is slidingly connected with the inner wall of the second communication groove 30 in the vertical direction.

[0037] A plurality of pressure sensors 32 are fixedly connected to the bottom of the lifting box 2, a rubber ring 33 is fixedly connected to the bottom of the lifting box 2, a sensing plate 34 is fixedly connected to the bottom of the rubber ring 33, the top end of the sensing plate 34 is connected with the bottom sensing end of the pressure sensor 32, and the sensing plate 34 is slidingly connected with the sidewall of the lifting box 2 in the vertical direction.

[0038] In the embodiment, a plurality of battery packs 39 are respectively installed in the lifting box 2, and are limited and guided by the guide block 4 and the guide groove 5. When the tram stops and is powered off, the standby power source controls the driving motor 37 to operate, drives the driving shaft 10 to rotate the threaded pipe 11, drives the fixed pipe 8 and the lifting box 2 to move downward through the threaded groove 12, and the limiting frame 25 slides downward along the inner wall of the fixed box 1. The inner wall of the lifting box 2 slides downward along the outer wall of the fixed frame 35, gradually exposes the first communication groove 29 and the second communication groove 30 around the lifting box 2, and the space in the lifting box 2 is communicated with the outside through the first communication groove 29 and the second communication groove 30. The filter screen 28 is arranged in the middle to filter the air entering and exiting. In this process, the threaded pipe 11 also drives the driving rod 16 to rotate through the driving groove 17, drives the first bevel gear 15 at the bottom to rotate, drives a plurality of second bevel gears 20 around to rotate, and drives the driving block 14 to move along the direction of the threaded rod 21 together with the battery pack 39, so that the battery pack 39 slides along the guide groove 5 to increase the distance between adjacent battery packs 39.

[0039] The sensing plate 34 at the bottom of the lifting box 2 senses the object below during the downward movement of the lifting box 2. When it hits the obstacle below, the sensing plate 34 is lifted up, so that the reading of the pressure sensor 32 increases. At this time, the driving motor 37 is controlled to stop operating and reversely rotate to control the lifting box 2 to move upward by a small distance, so as to avoid the sensing plate 34 continuously abutting against the obstacle.

[0040] After the lifting box 2 is lowered to the required position, the driving motor 37 stops running, at this time the battery pack 39 has a large spacing, and the external gas can pass through the filter screen 28 after being filtered, and then be transported to the surrounding of the battery pack 39 through the first communication groove 29, and then be discharged from all around after taking away the heat, thereby improving the natural heat dissipation efficiency of the battery pack 39, and at the same time, the battery pack 39 is far away from the vehicle body during the charging process. When the battery pack 39 is abnormal, the above-mentioned way of controlling the battery pack 39 to move downward and expand the spacing of the battery pack 39 can also be used. Then the valve of the storage box 22 is started to spray the material stored in the storage box 22 through the delivery pipe 23 and the spray head 24. The material in the storage box 22 can be a spray type aerogel, which is mixed by acrylic resin, aerogel powder, silane coupling agent, anti-settling agent, solvent and propellant, etc. It can be compressed and stored in the storage box 22, and after being sprayed, it expands and solidifies quickly to fill the gap around the battery pack 39. The material has a nano-porous network structure, can effectively block heat conduction, has light weight, good fireproof performance, is convenient and fast to use, has extremely low thermal conductivity, can effectively separate heat source and heat-sensitive elements, avoid heat transfer and fire spread, and improve the protection effect on the surrounding battery pack 39.

[0041] It should be noted that: in order to improve the cooling efficiency and protection performance of the battery during high-power output, the battery pack 39 generally needs to be fully enclosed and wrapped with a liquid cooling system for cooling and heat dissipation. The compactly arranged battery pack 39 can reduce the coverage area required by the liquid cooling system and improve the heat dissipation efficiency. When the battery is powered off, the gap of the battery pack 39 is increased, and the air flow with the outside is opened, which can improve the efficiency of natural wind cooling and make the air flow pass through the middle of the battery pack 39 to take away the heat.

[0042] After the bottom sensing plate 34 and the mounting rod 38 are removed, the filter screen 28 can be replaced and maintained. During the lifting process of the lifting box 2, the dust and impurities on the outer wall of the second communication groove 30 and the filter screen 28 can be scraped off by the cleaning teeth 31 on the supporting frame 26 to achieve preliminary self-cleaning and improve the service life of the equipment. When the electric vehicle starts, the driving motor 37 drives the threaded pipe 11 to rotate in the opposite direction, so that the lifting box 2 moves upward and the battery pack 39 slides to the middle. When the lifting box 2 rises to the uppermost position, the overall area of the battery pack 39 is smallest, which can reduce the coverage range of the liquid cooling system and improve the heat dissipation efficiency. At the same time, the first communication groove 29 and the second communication groove 30 are respectively blocked and sealed by the fixed frame 35 and the fixed box 1 to ensure the stability and safety of the battery pack 39 during high-intensity work.
