Description

Technical Field

[0001] The invention belongs to the technical field of fire fighting and extinguishing, and in particular relates to a fire extinguishing cover for an automobile. Background Art

[0002] The relatively closed environment of underground garages means that once a car fire occurs, the fire is likely to spread quickly. Traditional underground garage fire extinguishing systems, such as sprinklers, may have certain limitations. For example, there may be a delay in the activation of the sprinkler, or the fire may be too intense to be effectively controlled.

[0003] Since new energy vehicles are composed of battery systems, motor systems, electronic control systems and other parts, battery technology is not yet fully mature, and some fire prevention measures need to be further improved. The thermal runaway principle of batteries, battery aging and failure, line aging, short circuit, overload, collision and other factors can cause safety accidents, damage to the vehicle itself, and damage to surrounding vehicles and facilities. In addition, the causes of car fires are diverse, including circuit failures, fuel leaks, etc. When a fire occurs, high temperatures and toxic smoke will spread rapidly in a closed underground garage, posing a threat to other vehicles and the structural safety of buildings.

[0004] However, in the prior art, when a car spontaneously ignites, it is impossible to quickly isolate the burning car and burn it, which easily causes the fire to spread and cause fire in the surrounding environment, causing the fire to continue, thereby increasing the losses caused by the fire. For this reason, a car fire extinguishing hood is proposed.

[0005] Therefore, in the above background, the present invention proposes a car fire extinguishing cover which can quickly and effectively prevent the spread of car fires. The cover can directly cover the burning vehicle, isolate the air, prevent the continued combustion, buy time for fire extinguishing, and reduce the losses caused by the fire.
