Device for preventing combustion during new energy automobile crash

Abstract

The invention relates to the technical field of new energy automobiles, and discloses a device for preventing combustion of a battery during a new energy automobile crash. According to the device, buffer springs are arranged on the inner wall of a protection box, connecting blocks are fixedly connected to the opposite sides of the two buffer springs, push rods are arranged at the bottoms of the connecting blocks, connecting rods are arranged on the left sides of the push rods, second springs are arranged on the inner right wall of a dry powder box, a baffle is arranged on the left sides of thesecond springs, a movable rod is arranged on the right side of the baffle, gas storage cylinders are arranged in a battery box, gas inlet pipes are arranged on the inner bottom wall of the gas storage cylinders, connecting pipes are arranged on the outer sides of the gas inlet pipes, and heat dissipation ports are formed in the outer side of the battery box. The device has the advantages that anautomobile crashes into extrudes the connecting blocks, the movable rod moves to push the baffle plate to move, racks move to drive vertical rods to move downwards through fixed plates, the vertical rods move downwards to extrude the connecting pipes, the connecting pipes extrude springs outside the gas inlet pipes to move downwards, the air pressure of the gas storage cylinders is increased, gasenters the battery box through gas outlets, and dry powder is blown by the gas to be uniformly distributed in the battery box.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to an anti-combustion device for collision batteries of new energy vehicles. Background technique [0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as power sources, integrate advanced technologies in vehicle power control and drive, and form vehicles with advanced technical principles, new technologies, and new structures. Modern new energy vehicles are usually driven by pure electric power, which are generally powered by batteries for battery life. When installing batteries, they are usually installed on the chassis of the car, and protective devices and heat dissipation devices are installed outside the battery box to play a role. Protect the battery, and when the car collides, the battery is easily crushed and deformed or punctured by a hard object, causing it to burn violently or even explode. If the fire cannot be extinguished in ...
