[0002] Trucks, generally referred to as cargo trucks or trucks, include dump trucks, tractor trucks, off-road trucks for off-road and roadless areas, and various vehicles manufactured for special needs. They refer to cars that are mainly used to transport goods, and sometimes also refer to cars that can tow other vehicles. They belong to the category of commercial vehicles and can generally be divided into heavy and light types according to the weight of the vehicle. Most trucks use diesel engines as their power source, but some light trucks use gasoline, liquefied petroleum gas or natural gas.

[0003] When the doors of existing truck compartments are in use, the cargo stored inside will be sealed off after a fire occurs, but the fire source cannot be extinguished, which can easily cause greater economic losses and is highly dangerous. When a dry ice fire extinguisher is placed in the vehicle, it is difficult to automatically extinguish the fire, and the fire extinguisher needs to be replaced as a whole after use, which increases the cost of use and is not convenient for repeated use of the fire extinguishing equipment.
