[0002] The new energy vehicle chassis fire extinguishing device is a fire-fighting equipment specially designed for new energy vehicles. It is intended to quickly and effectively extinguish fires that may occur in the vehicle chassis. Since the battery system, motor and other high-voltage components of new energy vehicles (especially electric vehicles) are usually located near the vehicle chassis, once a failure or accident occurs, it may cause a fire, and the fire will spread rapidly, making it difficult to extinguish.

Accurate positioning data, the booster nozzle 706 enhances the injection pressure and coverage of the fire extinguishing agent, the first telescopic hose 707 and the second telescopic hose 15 are respectively connected to the first nozzle 705 and the second nozzle 16, ensuring that the fire extinguishing agent is efficiently transmitted from the storage container 5 to the first nozzle 705 and the second nozzle 16, the protection of the explosion-proof protective shell 3 ensures the safety of key electrical components such as the battery 4, and the design of the heat dissipation slot 12 helps to dissipate heat and extend the service life of the battery 4. The setting of the steering rod 9 and the tire 10 provides the mobility of the chassis body 1, making the entire system more flexible. The fixed installation of the bracket 8 and the supporting cross bar 13 enhances the structural stability of the chassis body 1 and provides a solid support for the adjustment of the mobile mechanism 2.
