Description

Vehicle fire extinguishing device

The present invention relates to a vehicle fire extinguishing device for automatically extinguishing a vehicle fire as the washer fluid is automatically injected by the temperature when a fire occurs in the vehicle.

Generally, a vehicle is equipped with various safety devices for driving stability, such as an anti-lock brake system (ABS), a seat belt, and an air bag for braking safety.

Such safety equipment has been increasingly mandated due to the recent tightening of safety regulations of vehicles. In particular, many developed countries have already mandated such safety equipment to be installed in export vehicles.

However, there are many different types of accidents that often result in a fire causing more casualties when the vehicle is overturned by collisions and falls or the engine overheats due to excessive driving.

Since such accidents are not foreseen, it is ideal to always have safety equipment ready for them.To this end, a vehicle-mounted fire extinguisher for the extinguishment of a vehicle fire is produced separately and installed by consumers. .

However, most drivers recognize vehicle fires as a very rare accident type, and in fact, fire extinguishers are rarely purchased and installed separately, but as the prevalence of vehicles increases, the proportion of vehicle fires among the types of accidents gradually increases. In the event of a fire like this, it is common to almost burn out because it is only a matter of waiting for a natural evolution or seeking help from a fire-fighting agency near you, especially when causing a fire. There is this.

Accordingly, the present invention is to provide a vehicle fire extinguishing device that can extinguish a fire while washer fluid is automatically injected by the flame temperature when a fire occurs by using the washer fluid injector pre-installed in the vehicle. Has a main purpose.

It is another object of the present invention to prevent the spread of fire at an early stage to prevent larger accidents.

As a means for achieving the above object, the present invention is connected to the power supply to the terminal terminal of the injection motor to be interrupted while being deformed by the thermal contact, and driven simultaneously with the injection motor to selectively open and close the washer liquid injection direction And a fire extinguishing nozzle which is fixedly mounted to an upper surface of the engine hood to allow washer fluid to be injected.

Referring to this in more detail with reference to the accompanying drawings, Figure 1 schematically shows an embodiment according to the present invention, 1 is an engine hood, 2 is a washer liquid reservoir tank.

The connecting means 40 is fixed to the bottom surface of the engine hood 10 directly above the engine, as shown in FIG. 2, and on both sides of the power supply terminal 41 and the injection motor 30 side terminal 42. As the connection means 40 is deformed by thermal contact, the connection between both terminals 41 and 42 is interrupted.

Reference numeral 60 denotes an actuator connected to the terminal 42 on the injection motor 30 side, and is supplied by the injection motor 30 mounted on the washer fluid reservoir tank 20 to supply washer fluid guided through the supply pipe 50. Flow direction switching means for changing the direction.

Therefore, the washer liquid guided from the injection motor 30 through the supply pipe 50 is branched into two supply pipes 50 through the actuator 60, and one side is connected to the windshield nozzle 70, and the other side is The fire extinguishing nozzle 80 is connected to the structure.

Meanwhile, in the above structure, the connecting means 40 may use a shape memory alloy that can be deformed by thermal contact. However, since the connection means 40 is expensive, it is more preferable to use a cheaper bipetal, and the actuator 60 The furnace may be a stepper motor or a solenoid valve.

In particular, the fire-extinguishing nozzle 80 should be larger than the spray angle and the injection amount of the conventional windshield nozzle 70, and the spraying direction is most preferably to be sprayed to the cabin side and the engine room side at the same time. .

2, the power supply to the terminal 42 and the actuator 60 of the injection motor 30 is cut off by the connecting means 40, and as shown in FIG. The injection motor 30 is driven by the mounted multi-function switch, the fire extinguishing nozzle 80 side is closed by the actuator 60 and the windshield nozzle 70 side is opened so that the injection motor 30 is opened. The washer fluid pumped by) is injected into the windshield nozzle 70 only.

In such a state, when a fire occurs due to collision, overturning, or overheating of the engine, the connection means 40 attached to the engine hood 10 is deformed by the heat of fire, and the power supply terminal 41 and the injection motor 30 are fired. The side terminals 42 are connected to each other so that the actuator 60 is operated simultaneously with the injection motor 30.

Therefore, the washer fluid is pumped by the injection motor 30, and the fire-fighting nozzle 80 which is closed by the actuator 60 is opened while the windshield nozzle 70 that is open on the contrary is closed. The washer fluid is sprayed through the fire extinguishing nozzle 80 to the vehicle compartment and the engine room at the same time to extinguish the fire and to prevent the fire from spreading.

This operation causes the washer fluid to continue to be injected until the washer fluid is exhausted in the washer fluid reservoir tank 20, that is, while the preloaded washer fluid level sensor detects that the washer fluid is exhausted, and the power supply is interrupted.

Therefore, when a fire occurs in the vehicle, the vehicle itself recognizes the fire by the connecting means 40, and immediately operates the injection motor 30 and the actuator 60, thereby enabling early fire extinguishing. It can also prevent the spread of fire.

Therefore, according to the present invention, the vehicle itself is recognized and extinguished a fire occurrence, thereby improving stability, and at the same time, it is not necessary to have a separate fire extinguishing tool, which is very useful to operate safely with no hassle. Will provide an effect.
