Integrated fire suppression device of electric motor coach

The invention discloses an integrated fire suppression device of an electric motor coach, and belongs to the technical field of safety of electric motor coaches. Comprising a battery box and further comprises a passenger car air compressor, a fire extinguishing device and a nitrogen protection device, the passenger car air compressor provides pressure for the fire extinguishing device to extrude out a fire extinguishing agent, the passenger car air compressor provides a nitrogen source for the nitrogen protection device, and the output end of the fire extinguishing device and the output end of the nitrogen protection device both communicate with the battery box. The fire extinguishing device is of a pressure driving type. According to the integrated fire suppression device suitable for the electric motor coach, only one pipeline communicated with the battery box is needed, the thermal runaway probability can be reduced before thermal runaway of the battery box, rapid suppression can be conducted after thermal
