Abstract
The invention provides a new energy vehicle battery box which comprises a box body and a box cover, the box body further comprises different functional intervals, a battery containing cavity is located in the middle area, different isolation cavities are arranged on the periphery of the battery containing cavity, and when a fire occurs, the isolation cavities can prevent the battery containing cavity from making contact with other parts of a new energy vehicle to a certain extent, and the influence of the fire on other parts of the vehicle is reduced. A driving device is arranged in the battery box and comprises a driving roller, a ventilation channel is arranged in the driving roller, and heat in the battery box can be discharged through the ventilation channel. When fire occurs in the battery containing cavity and the temperature suddenly rises, the driving roller is driven by a balancing weight to rotate, the ventilation channel is closed, and an external oxygen supply path is cut off. Meanwhile, a driving rod and a supporting rod which are arranged on the driving roller are in linkage with a baffle in the box cover, the baffle rotates under the thrust action of the driving rod, a dry powder extinguishing agent in a dry powder cavity is scattered into the battery containing cavity along a notch of the baffle, combustion is stopped, and recombustion is prevented.
Description
technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a battery box of a new energy vehicle. Background technique [0002] New energy vehicles mainly include hybrid vehicles and pure electric vehicles. Among them, pure electric vehicles are vehicles that use a single battery as an energy storage power source. Thereby driving the car. Batteries are the core components of new energy vehicles, especially pure electric vehicles. Batteries usually need to be placed in a matching battery box to reduce the adverse effects of external environmental factors on battery performance. [0003] The discharge performance of the battery is greatly affected by the ambient temperature. During the operation of new energy vehicles, the battery itself will continue to release heat. If the high temperature of the external environment is added, the discharge performance of the battery will be seriously reduced. For this reason, the battery ...
