Description

The fire repression apparatus of an electric vehicle The present invention relates to a fire suppression device for an electric vehicle, and more specifically, to a fire suppression device for an electric vehicle in which, when a fire occurs in an electric vehicle, a fireproof blanket falls from above the parked vehicle to cover the electric vehicle, thereby preventing the spread of the fire and suppressing the fire by blocking the oxygen necessary for combustion. In the case of ordinary automobiles, since they are driven by internal combustion engines, there were problems such as causing air pollution due to exhaust gases. For this reason, electric vehicles have recently been attracting attention. Since electric vehicles are driven by motors powered by batteries, they can prevent air pollution by eliminating exhaust emissions, reduce driver fatigue due to minimal noise during driving, and lower maintenance costs by reducing the number of parts; consequently, their adoption is rapidly increasing as they replace conventional automobiles using internal combustion engines. However, electric vehicles had a problem where it was difficult to extinguish a fire when it occurred. In other words, when a fire occurs in an electric vehicle's battery pack due to external impact or internal short circuit, it is difficult to extinguish the fire in its early stages due to thermal runaway phenomena, and as the fire spreads to surrounding vehicles, there was a problem in which the damage from the fire increased. For this reason, when a fire occurs in an electric vehicle, specialized equipment such as a 'mobile water tank' disclosed in Korean Public Patent No. 10-2022-0146971 is used to suppress the fire; however, since specialized equipment for suppressing electric vehicle fires is limited and is installed only in specific regions or locations, there was a problem in that it was difficult to extinguish the fire using such equipment if it occurred outside of those regions or locations. In addition, there were fire extinguishing devices for electric vehicles that sprayed extinguishing water in addition to 'mobile water tanks,' but conventional fire extinguishing devices for electric vehicles only sprayed water over the entire vehicle, and since it was difficult to concentrate the spraying of water on the point of fire, particularly on parts of the battery pack, there was a problem of reduced extinguishing efficiency. For the reasons mentioned above, the field is attempting to develop fire extinguishing devices for electric vehicles that enable rapid initial fire suppression by concentrating the spraying of extinguishing water onto high-temperature areas caused by a fire in the battery pack; however, satisfactory results have not been achieved to date. Another type of electric vehicle fire extinguishing device is also disclosed, which quickly suppresses the fire by wrapping the electric vehicle in a suffocating blanket at once to suffocate it when a fire occurs in the electric vehicle, thereby preventing the fire from spreading to neighboring electric vehicles and surrounding spaces. However, the aforementioned fire extinguishing device for electric vehicles required a large number of parts and occupied a significant amount of space, which resulted in inconvenience during use and limitations on space utilization. The technical configuration described above is provided as background technology to aid in understanding the present invention and does not constitute prior art widely known in the technical field to which the present invention belongs.
