Description

Vehicle fire extinguisher

[0001] The present invention relates to a device for suppressing fires in various vehicles, including electric vehicles, and more specifically, to a vehicle fire extinguishing device in which a frame and a rotary movable frame can be folded and unfolded in the forward / backward and / or left / right directions to facilitate storage and transport, and which can selectively combine a fire extinguishing fluid supply unit, an inert gas supply pipe, a suction unit, etc., while covering the burning vehicle with a fire extinguishing cover to reduce oxygen inflow.

[0002] In electric vehicles, thermal runaway may occur due to internal short circuits, charging abnormalities, or external impacts of the high-voltage battery, which may result in fire and the generation of harmful gases (e.g., hydrogen fluoride).

[0003] Conventionally, automatic fire extinguishing systems fixed in specific locations have been proposed; however, this approach makes it difficult to respond to vehicle fires occurring at other locations as the system moves outside the installation site. Therefore, there is a need for a mobile / deployable fire suppression device capable of moving to various sites, such as outdoor and underground parking lots.

[0004] The present invention aims to provide (1) a device that can move to the site where a fire vehicle is located and easily extinguish a fire, (2) a device that can be stored in a confined space by reducing its volume through folding and unfolding in the front-rear and / or left-right directions, (3) a device with excellent transportability and accessibility, and (4) a device that can selectively combine functions such as a cover membrane, supply of fire extinguishing fluid, supply of inert gas, and intake of harmful gas.

[0005] According to one embodiment, a vehicle fire extinguishing device comprises a frame and a rotary frame in which the front portion is axially coupled to the rear portion of the frame and folds and unfolds as the rear portion rotates in the front-rear direction.

[0006] According to another embodiment, the frame is divided into a second frame and a first frame, and the first frame is axially connected to the second frame via a hinge axis so that it can be folded and unfolded as it rotates in the left and right directions. At this time, the rotational movement frame is divided into a second rotational movement frame and a first rotational movement frame, and the second rotational movement frame and the first rotational movement frame are connected by a separate axis, etc., so that the forward and backward rotational unfolding and left and right folding movements can be combined.

[0007] A fire extinguishing fluid spraying member may be disposed on the inner side of the rotary moving frame, and fire extinguishing fluid may be supplied to the frame and / or the rotary moving frame and / or the fire extinguishing fluid spraying member through a fire extinguishing fluid supply unit. Additionally, a fire suppression cover membrane covering a fire vehicle may be configured to unfold in conjunction with the deployment of the rotary moving frame, and may optionally include a wheel unit, a height adjustment unit, a camera unit, a light-emitting unit, an outlet, an inlet, a suction unit, etc.

[0008] According to the present invention, the frame and the rotary moving frame can be folded and unfolded to reduce storage volume, and can be moved to the location of the vehicle on fire to reduce oxygen inflow by covering it with a cover film, and can selectively perform the supply of fire extinguishing fluid, supply of inert gas, and absorption of harmful gases, thereby improving on-site responsiveness to vehicle fires.
