Description

Device of fire-spread prevention for vehicle}

The present invention relates to a device for preventing the spread of fire in automobiles, and more specifically, to a device installed on the roof of a automobile so that when a fire is detected through sensors installed in each part of the automobile body, a fire-fighting sheet is automatically deployed to cover the burning vehicle. This relates to a fire spread prevention device for a car that prevents the fire from spreading not only to the burning car but also to other nearby cars.

Cars, which are the most useful means of human transportation, are equipped with many convenience features along with technological advancements. So far, internal combustion engine cars that use fossil fuels as an energy source have been the mainstream, but due to the problem of emitting environmental pollutants. As a result, internal combustion engine vehicles, which were based on fossil fuels, are increasingly moving toward hybrid and electric vehicles.

Automobiles can be said to be an integration of technology with various systems such as fuel and power systems, driving systems, electrical systems, and safety systems. As many parts are assembled and used, the causes of breakdowns and safety accidents are very diverse.

In particular, when an accident occurs in a running vehicle, or in addition to an accident, it is related to deterioration of tires that continuously rub against the ground, deterioration of various belts used in power transmission, oil leaks used in each drive system, and fuel supply and control. Fires often occur due to deterioration of electrical and electronic systems, overcurrent, or battery explosion.

In particular, as the use of large-capacity, high-efficiency batteries is increasing due to technological development and transition from vehicles using internal combustion engines to hybrid and electric vehicles, the high heat generated from the battery side can cause malfunction and overheating of electrical and electronic devices. As a result, the risk of fire occurrence is increasing.

In this way, when a fire breaks out in a running car, it easily spreads to the car body or interior through the fuel system or power system, causing the car to burn down in an instant.

When a fire breaks out in a car, the fire usually spreads significantly in a short period of time, so in most cases, the fire cannot be extinguished until the fire truck arrives other than the driver evacuating the vehicle, resulting in great economic damage.

In addition, even if a fire breaks out in a car alone, if there are other cars parked nearby, such as in a parking lot, the fire can easily spread to nearby vehicles and develop into a large-scale fire. In the event of a car fire, fire suppression is carried out quickly at the beginning. It is more important than anything else to do so.

Looking at the conventional technology to prevent or suppress such car fires, ‘vehicle fire suppression device’ of Patent Registration No. 10-0391517 (2003.07.02) has been developed.

The 'vehicle fire suppression device' of the above invention allows the electronic control device to prevent electric leakage and oil leakage by sensors mounted on the vehicle in the event of a vehicle collision. To this end, it includes a sensor unit that detects the impact state of the vehicle; A fuel motor pump that supplies the fuel filled in the vehicle's fuel tank, a battery that supplies power to various electrical devices installed in the vehicle, and a device that determines the impact state of the vehicle from the signal output from the sensor unit and then determines the impact state. Accordingly, an electronic control device that outputs an operation stop signal to the fuel motor pump to prevent leakage or electric leakage in advance and outputs an operation signal to the current automatic cut-off device connected to the battery to cut off the power current of the battery is used to prevent shock. Depending on the degree, technology has been disclosed to prevent fires from occurring due to oil leaks and short circuits.

In other words, the above invention is intended to prevent the cause of a fire in advance by blocking the current on the battery side and stopping the operation of the fuel motor pump under the control of the electronic control device in the event of a vehicle collision, and is an action taken after a fire occurs in the vehicle. The means by which this can be done are not separately presented.

In addition, Utility Model Registration No. 20-494734 (2021.12.07) ‘Add a fire extinguishing nozzle to the cowl assembly to extinguish fires in the automobile engine room’ has been proposed.

In the case of the above design, it is a device for extinguishing a fire occurring in the engine room of a car. In the case of an internal combustion engine vehicle, it may be useful as the possibility of a fire occurring in the engine room is high, but it is not practical for hybrid and electric vehicles that use a battery as a power source. It was a falling idea.

In addition, many other designs and inventions have been created, but most of them are equipped with fire extinguishing agents inside the car body to prevent fires from occurring in the engine room where the engine, which is a core component of an internal combustion engine vehicle, is installed, or to extinguish fires by spraying fire extinguishing agents or using fuel. It consists of technologies such as cutting off the supply and cutting off the current through an electronic control device.

The technical configuration will be explained in detail with reference to the attached drawings.

Figure 1 shows an external perspective state of a vehicle (V) installed with a fire spread prevention device 100 for a car according to an embodiment of the present invention, and Figure 2 shows a fire spread prevention device for a car according to an embodiment of the present invention. The main configuration of (100) is briefly shown in a block diagram.

As shown in FIG. 1, the fire spread prevention device 100 according to an embodiment of the present invention is installed on the roof (R), the uppermost side of the vehicle, and is a storage box with a fire seat sealed so as not to interfere with vehicle driving. It is installed in a built-in state inside (10).

The storage box 10 has a structure that opens automatically through a signal detected by a plurality of sensors installed in the vehicle, and one cover 15 of the storage box 10 has a structure that seals all four sides and two It is desirable to have a structure that is divided into two or more parts and can be opened on two or more sides.

In Figure 2, the main components required for the deployment operation of the storage box 10 and fire protection sheet loaded and installed on the roof (R) of the vehicle (V) are briefly shown as a block diagram.

As shown in FIG. 2, the main part of the fire spread prevention equipment 100 according to the embodiment of the present invention is the interior of the vehicle and the main part of the car body, that is, in the case of an electric car, the battery loading on the bottom of the car body floor where the battery is loaded. A gas detection sensor 32 and a flame detection sensor 34 are installed in the unit.

In other words, a human body detection sensor 30 is installed in the interior of the vehicle to detect whether there are passengers inside in the event of a fire, and the battery loading part of the vehicle body has a sensor to detect a fire occurring due to high heat of the battery. A gas detection sensor 32 and a flame detection sensor 34 are installed respectively, and a warning means 36 is installed in the interior of the vehicle to warn passengers of the occurrence of a fire in the event of a fire.

In addition, signals from the human body detection sensor 30, gas detection sensor 32, and flame detection sensor 34 are received inside the vehicle to determine whether a fire has occurred and whether passengers are on board, and when it is determined that a fire has occurred. A fire suppression integrated module 50 that controls the warning means 36 to output a warning signal is installed.

The fire suppression integrated module 50 includes a passenger boarding determination unit 52 that analyzes the signal received from the human body detection sensor 30 to determine whether a passenger is riding inside the vehicle, and the gas detection sensor ( 32) and a gas generation determination unit 54 and a flame generation determination unit 56 are provided to determine whether gas or flame above an appropriate standard value is being generated based on the signal detected by the flame detection sensor 34.

In addition, if the gas generation determination unit 54 and the flame generation determination unit 56 determine that the safety of passengers is at risk due to gas or flame generation, a warning signal can be output through the warning means 36 installed indoors. A warning means control unit 57 is provided so that

In addition, when the fire suppression integrated module 50 determines that a fire has occurred due to gas or flame being generated in the gas generation determination unit 54 and the flame generation determination unit 56, the fire suppression integrated module 50 is installed on the roof of the vehicle. A fire protection box opening control unit 58 for deploying a fire suppression sheet, a fire protection sheet deployment control unit 59 for controlling the fire protection sheet stored therein to be deployed after opening the storage box, and overall control and control of each of the above parts. It consists of a central control unit 51 in which the necessary programs are stored.

To further explain the configuration of each of the above-described sensors, the human body detection sensor 30 is a sensor for detecting passengers riding indoors, and when a vehicle fire occurs, it detects if there are passengers riding indoors and provides a fire suppression integrated module. A signal is sent to (50), and the fire suppression integrated module (50) notifies the fact that a fire has occurred through the warning means (36) installed indoors, allowing passengers to quickly evacuate from the vehicle where the fire occurred, thereby preventing personal injury. It is configured to prevent this from occurring.

The human body detection sensor 30 applied to the embodiment of the present invention is configured to detect indoor passengers in a non-contact manner, and in a preferred embodiment, a PIR (Passive Infrared Sensor) is applied.

The PIR sensor refers to a passive infrared sensor, which detects the movement or movement of the human body within a certain range through a Fresnel lens. Since it consumes little current, it can be operated for a long time without external power supply and can be miniaturized. Therefore, it is convenient to install anywhere indoors.

Additionally, as another embodiment of the human body detection sensor 30, it may be configured to detect the human body by installing an infrared temperature sensor indoors.

The infrared temperature sensor converts the optical signal that collects infrared rays radiating from the human body into an electrical signal and then determines the temperature through electrical signal processing. It has higher accuracy than other types of temperature sensors, allowing passengers to enter the vehicle interior. Make it possible to accurately detect whether something is being done or not.

The human body detection sensor 30 is installed in one or more units according to the interior structure and size of the vehicle, and is configured to effectively determine whether a passenger is on board. The structure and operating principle of the PIR sensor and infrared temperature sensor are known. Since it is a technology, detailed description thereof is omitted in the present invention.

In addition, the gas detection sensor 32, which detects gas that may be generated due to overheating of the battery, etc., uses a contact combustion method, and the gas detection sensor applied to the present invention uses the MQ-2 sensor of Sunfounder. did.

The gas detection sensor 32 can be used in Arduino and at low power, and can detect LP, butane, propane, methane, alcohol, hydrogen, smoke, etc., and has a built-in heater to dissipate heat. This is a method that can detect the gas concentration by absorbing the gas generated.

In addition, the flame detection sensor 34 is a sensor that detects ignition at a short distance, and detects whether a fire has occurred by detecting infrared rays generated from the flame when ignition, and the gas detection sensor 32 or flame detection sensor ( 34) is a well-known technology that can be purchased in module form and is widely used in various fields, so a detailed description thereof will be omitted.

In addition, the warning means 36 installed inside the vehicle can be implemented with sound or light, and it is preferable to install it in a location where passengers can easily identify the warning means, which outputs a signal to the warning means 36. The control unit 57 determines that gas or fire has occurred in the gas generation determination unit 54 and the flame generation determination unit 56 based on the signals detected by the gas detection sensor 32 and the flame detection sensor 34. When this occurs, the warning signal set as the warning means 36 is controlled to be output.

Of course, in the case of the gas detection sensor 32 or the flame detection sensor 34, it is configured in a module form so that a warning sound or warning light can be emitted from the board on which the sensor is installed. However, a passenger inside the vehicle cannot hear the warning signal. Since it is difficult to recognize, it is preferable that the fire suppression integrated module 50 be configured to send a separate alarm signal to the warning means 36 installed indoors through the warning means control unit 57.

In addition, the central control unit 51 determines that gas or flame has been generated in the battery on the vehicle body through real-time information identified by the passenger boarding determination unit 52 based on the signal detected by the human body detection sensor 30 installed in the interior. In this case, a warning signal is sent to the interior of the vehicle through the warning means control unit 57, and then, if it is determined that there are no passengers inside the vehicle, it is sent to the storage box opening control unit 58 and the fire seat deployment control unit 59. A signal is sent to ensure that the storage box (10) installed on the roof (R) of the vehicle is opened and the firefighting sheet is deployed in order.

The control signal output required for deployment of the storage box 10 or the fire seat from the storage box opening control unit 58 and the fire seat deployment control unit 59 is configured to operate only when there are no passengers inside the vehicle, so that the passengers can safely evacuate. After doing so, the firefighting sheet is configured to be deployed.

Meanwhile, Figure 3 shows the cover 15 of the storage box 10 installed on the roof (R) of the vehicle in an open state.

When an opening signal is output from the storage box opening control unit 58 to the storage box under the control of the central control unit 51, the cover 15 is automatically opened by the operation of the storage box automatic opening means 11 installed on the roof (R). is opened to

The storage box 10 is intended to store the firefighting sheet 20 inside, and has a structure sealed on all sides so as not to interfere with vehicle operation, and is provided with one or more openable covers that can be opened automatically. It consists of a structure.

In addition, the firefighting sheet 20 loaded inside the storage box 10 is folded to a certain size and stacked up and down as shown in FIG. 3, and when the firefighting sheet 20 is deployed, it is positioned at the front of the vehicle. It can be stacked folded in various shapes and directions or rolled into a roll so that it can be easily unfolded to the sides and rear.

Figure 4 shows a state in which the fire seat 20 is deployed to the front and rear of the vehicle V according to a control signal from the fire seat deployment control unit 59 on the fire suppression integrated module 50 side.

The fire seat 20 is deployed by the fire seat automatic deployment means 70 provided on the bottom of the storage box 10, so that the front and rear ends of the fire seat 20 are unfolded to the front and rear sides of the vehicle, thereby protecting the vehicle body. It is designed to cover.

A certain weight 22 is added to the front and rear sides of the fire sheet 20 so that the fire sheet stacked up and down or the fire sheet wound in a roll can be smoothly unfolded when the fire sheet automatic deployment means 70 is operated. It can be composed of:

That is, the weight body 22 provided at the front and rear ends of the fire seat 20 moves the front and rear ends of the fire seat 20 to the front and rear of the vehicle by its own weight when the automatic fire seat deployment means 70 operates. By allowing the firefighting sheet to be pulled while flying, the firefighting sheet (20) quickly covers the entire vehicle, preventing the fire on the vehicle side from spreading further to the outside, and also blocks the inflow of external air into the fire occurrence area on the vehicle side, thereby quickly Make digestion possible.

The weight 22 serves as a weight when deploying the fire seat, allowing the fire seat 20 to be spread out widely, and at the same time preventing damage to other items when flying to the front of the fire vehicle and hitting another vehicle or object. It is more preferable to be configured to have a certain elasticity.
