[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: an electric new energy vehicle fire extinguishing mechanism, comprising a battery compartment, a compartment cover is installed on the battery compartment, a fire extinguishing agent storage tank is installed on the outer surface of the compartment cover, a pressurizing pump is installed inside the compartment cover and is connected to the fire extinguishing agent storage tank.

[0007] A plurality of connecting pipes are evenly installed on the inner side of the compartment cover, and the connecting pipes are connected to each other.

[0008] Preferably, a plurality of fixing seats are installed on the inner side of the compartment cover to limit the position of the connecting pipes.

[0009] Preferably, two clamping grooves are formed in the fixing seat, and the two clamping grooves are distributed perpendicular to each other.

[0010] Preferably, an adapter and a spray head are installed between the connecting pipes.

[0011] Preferably, a connecting head is installed on the pressurizing pump, and the connecting head is connected to the connecting pipe.

[0012] Preferably, a temperature sensor is installed inside the battery compartment to detect the temperature.

[0013] Compared with the prior art, the beneficial effects of the utility model are that: through the connecting pipe and the spray head which can be arranged at will, the installation work of mutual cooperation can be carried out according to the arrangement mode of the battery pack, the spray head is aimed at the position where thermal runaway is easy to occur, and then the fire point can be extinguished efficiently and quickly.
