These fires not only threaten the lives of passengers, but also cause huge property losses. Traditional on-board fire extinguishing equipment mainly targets fire sources inside the vehicle. However, for fires in the chassis, the fire extinguishing effect is not ideal due to its hidden location, and firefighters also face greater risks and operational difficulties during the fire extinguishing process. Although there are already some fire extinguishing devices on the market, there are still some disadvantages such as small fire extinguishing range and difficulty in carrying. Therefore, it is particularly necessary to develop a mobile fire extinguishing device specifically for new energy vehicle chassis fires. Utility Model Content
