New energy automobile magnesium alloy electric appliance box shell

Abstract

The invention discloses a new energy automobile magnesium alloy electric appliance box shell which comprises a shell. Two symmetrical isolation plates are arranged in the shell and arranged at the two ends of the shell correspondingly, fire extinguishing air bags are arranged between the isolation plates and the inner wall, on the same side, of the shell, moving plates are arranged at one ends of the isolation plates, the moving plates are connected to the top of the shell through a guide rod, a push rod is fixedly connected to the end, close to the side wall of the shell, of the moving plate, a plurality of baffles are fixedly connected to the side, close to the side wall of the shell, of the push rod, a plurality of heat dissipation holes are formed in the side wall of the shell, and the heat dissipation holes and the baffles are arranged in a one-to-one correspondence mode. And an electrified coil is mounted at the top of the shell. According to the new energy automobile magnesium alloy electric appliance box shell, the temperature sensor is arranged in the shell, the temperature of the battery in the shell can be monitored in real time and fed back in time, and the situation that the temperature of the battery in the shell is too high or the spontaneous combustion phenomenon occurs, and the use safety of the automobile is affected is prevented.

Description

technical field [0001] The invention relates to the technical field of new energy vehicle batteries, in particular to a new energy vehicle magnesium alloy electrical box shell. Background technique [0002] Because the battery uses lead-calcium alloy as the grid, the amount of water decomposition generated during charging is small, and the amount of water evaporation is also low. In addition, the outer shell adopts a sealed structure, and the sulfuric acid gas released is also very little, so it is compared with traditional batteries. , has the advantages of no need to add any liquid, docking the wiring pile head, and long power storage time. In new energy vehicles, the battery is an essential and important component. [0003] When the battery is in use, it is usually installed in the car. Because the car is prone to high temperature when driving, the battery is prone to spontaneous combustion when encountering high temperature, resulting in the spread of fire. At the same t...

Problems solved by technology

[0003] When the battery is in use, it is usually installed in the car. Because the car is prone to high temperature when driving, the battery is easy to spontaneously ignite when encountering high temperature, resulting in the spread of the fire. At the same time, there is an explosion phenomenon, and the battery itself often does not have the fire extinguishing function.
