[0040] In summary, when using the multifunctional battery bracket for new energy vehicles, install the entire device to the chassis of the vehicle through the mounting frame 1, and then connect the corresponding pipelines. The device is provided with a sealed shell 3, and the sealed shell 3 The battery is encapsulated to protect the battery. A shock-absorbing and shock-proof mechanism 2 is provided between the sealed shell 3 and the mounting frame 1. The connecting frame 201 is fixed on the mounting frame 1, and can be moved vertically on the sliding column 203 through a sliding sleeve 202. The spring 204 is used for buffering and damping, so that when the sealed shell 3 is subjected to impact and vibration, it can be buffered and damped to protect the battery loaded inside. The device is equipped with a battery quick loading and unloading structure. When the battery needs to be installed, the lifting motor 6 (model For SIC-41CVJ-F127-4) rotate the stud 7 to drive the screw sleeve 8 and the connecting frame 9 to move downwards, so that the anti-collision bottom shell 10 and the battery bracket 14 move downwards, so that the battery is lower than the car chassis, and then Move the battery bracket 14 and the battery horizontally in the sliding groove 12 on the anti-collision bottom shell 10 through the connecting sliding seat 13, thereby sliding the battery bracket 14 and the battery sideways, and then the battery can be repaired and replaced. After maintenance and replacement, slide the battery bracket 14 and the battery inward, the lifting motor 6 rotates the stud 7, and the screw sleeve 8 and the connecting frame 9 are driven to move upward, so that the anti-collision bottom shell 10 and the battery bracket 14 are moved upward Move until the anti-collision bottom shell 10 and the loading and unloading opening 5 are closed, and at the same time, a waterproof ring 11 is provided on the outside of the anti-collision bottom shell 10, which can maintain the sealing performance between the loading and unloading opening 5 and the anti-collision bottom shell 10 to prevent water ingress. At this time, the battery attachment sheet 2101 can be attached to the loaded battery to conduct heat, and the battery attachment sheet 2101 is evenly arranged with a plurality of heat dissipation fins 2102 in the horizontal direction to conduct heat on the heat dissipation fin 2102, and The radiating fins 2102 are parallel to each other to facilitate the dissipation of heat and improve the heat dissipation efficiency, and the radiating fins 2102 are interspersed with radiating pipes 2103, and the radiating pipes 2103 are circulated through the circulating pump 2104 (model TL-C01-B/1) The cooling water in the water tank 2105 is transmitted to improve the heat dissipation efficiency. At the same time, the radiating fins 2102 are installed in the wind box 16. The two sides of the wind box 16 are connected with air ducts 17, and the air enters through the air inlet 18 and passes through the radiating fins 2102. The heat is dissipated and then discharged from the air outlet 20 to form an air channel to increase the air flow speed and prevent the accumulation of hot air, thereby further improving the heat dissipation efficiency of the device. At the same time, a filter 19 is installed at the air inlet 18 and the air outlet 20 to prevent impurities When dust enters the device, electric vehicles generally use lithium batteries with higher energy density, but lithium batteries are very easy to catch fire, and a large amount of high-temperature gas will be ejected during a fire. Therefore, general gas or powder fire extinguishing agents are not effective, while water It can evaporate and absorb heat. A large amount of water can reduce the temperature of the battery to achieve the effect of control and fire extinguishing. Therefore, water is a good fire extinguishing agent when a lithium battery catches fire. When the battery is overheated and catches fire, the temperature sensor 15 (model ATS1- 82) The temperature is too high and the data is sent to the center of the car The processor, and the central processor controls the solenoid valve 2201 (model Z3CD) to open, so that the cooling water in the water tank 2105 can be sprayed out through the water outlet 2204 on the sprinkler pipe 2203 to reduce the battery temperature, alleviate the battery fire, and suppress the fire At the same time, when the lithium battery catches fire, a large amount of high-temperature gas is sprayed to impact the sealing plate 2305, which causes the sealing plate 2305 to rotate outward through the connecting shaft 2303, thereby releasing the high-temperature gas, preventing the gas volume pressure from causing an explosion in the sealing shell 3, and limiting The bit block 2302 limits the angle at which the sealing plate 2305 rotates to the outside, so that the gas impact direction is the ground, preventing secondary accidents caused by high-temperature gas impact to the side, and is safer. In this way, the entire multi-function battery bracket for new energy vehicles is completed. Use process.
