Description

Preventive device for preventing vehicle fires

The invention belongs to a fire-fighting technology for vehicles, and further relates to a fire-fighting device for preventing a fire in a vehicle, so as to prevent the vehicle from being extinguished after the fire, and to ensure the safety of the occupant and reduce the damage of the vehicle.

According to analysis, vehicles must have at least three conditions under fire: one is flammable; the other is fire source and high temperature; the third is air. Flammable products mainly refer to fuels such as gasoline, diesel oil, engine oil, liquefied gas (LPG) or ethanol. They leak oil or fuel oil and gas due to rupture of pipes and loose joints. The fire source is the spark caused by the start of the generator, the starter, etc., and the vehicle components are leaking and malfunctioning due to the deterioration of the old day, and the fire source may also be generated, such as the battery wire, the high voltage wire rupture, the ignition coil, the distributor, etc. Old electricity leaks and generates a fire source. High temperature refers to the high temperature space generated by the operation of the vehicle. High temperatures tend to make flammable products more likely to catch fire, and these ignition points are mainly concentrated in the engine room and the fuel tank. In addition to car overheating, in addition to overheating, the main reason is that the spark is exposed to the leaking sleeves of the flammable product, causing spontaneous combustion and ignition. As for the cause of the spark, in addition to leakage, the most important factor comes from the vehicle accident. The collision is caused by the collision of the battery, especially the impact of the electric shock caused by the electric shock.

Traditionally, in order to prevent fires caused by self-ignition or car accidents caused by overheating, oil leakage, electricity, etc., some owners will place fire-fighting equipment in the vehicle for fire-fighting preparation, but in fact, use such fire extinguishers. When the occupant needs to be awake and can open the hood to spray fire outside the vehicle, but when the engine room is smoldering, if the hood is opened, the fire will be intensified by the inhalation of air, which is called "smoke". The effect, on the other hand, forms another hazard. In addition, when a vehicle crashes, the occupants often faint, waking up, waking up, or being trapped in the car, and the vehicle is prone to fire due to severe impact. At this time, the occupant is not only self-help. Self-rescue, and others outside the car can not get close to timely rescue, and the occupants often lose valuable life, and the vehicles are scrapped because they cannot be repaired due to burning.

In order to overcome the above-mentioned 3⁄4 problem, some have developed a variety of fire-fighting equipment for vehicles, such as "Automatic Fire Fighting System for Automobiles," and "Automatic Fire Fighting System for Vehicles, No. M261230" of the TW Patent Publication No. 590926 In 200637630, "automobile active fire-fighting devices, etc., are to use fire-fighting equipment such as smoke, flare or temperature to connect fire-fighting equipment. When the above-mentioned induction components detect that the car is on fire, directly fire the fire-fighting equipment to extinguish the fire. However, in terms of experience and practice, when such a fire protection system is used, the vehicle must have smoldering and igniting, and the sensing components such as smoke, fire or temperature will start to extinguish the fire. When the fire is burning for a while, the vehicle is in use. Warm, easy-to-fuel products and traffic vehicles that are prone to sparks and air circulation, etc., which are easy to burn or even explode. The vehicle is not only easy to catch fire but the fire is easy to over-speed, and the fire-fighting unit cannot effectively extinguish it in real time. fire vehicle device or the like, due to many components or line contacts, in general, more electronic components which contacts the vehicle, the higher the failure rate _f in a car accident, especially severe impact in case of failure or loose its common, or During the burning process of the vehicle, there is no sensing component in the ring. No H is sensed to open the fire extinguishing equipment, and the fire extinguishing machine is lost. In addition, the vehicle is easy to catch fire, such as the engine room. It is necessary to fully set the sensing components. The quantity and type need to be A lot of fires and fires are not happening. · Smoke and smoldering are effective for detecting smoke sensors. When an explosion is fired, the flame sensor is detected effectively. As for the temperature sensor, if the fire detection equipment is activated, the actual fire extinguishing equipment is activated. On the other hand, the vehicle has reached a certain level of fire, and the cost of these detection equipment is not costly. Cost europium open, but the owner is not easy to accept. In the case of vehicles without fire-extinguishing devices, the life and property of the occupants are not guaranteed to be more secure.

Therefore, after intensively studying the vehicle fire process, the inventors concluded that it is best to prevent and control the occurrence of vehicle fires. The key point is the time of ignition (golden time) and the control method. In the analysis of the fire point, the focus is on the pre-fire prevention action, not the fire action after the fire. The method of controlling the fire extinguishing is as follows: 1. After the vehicle is hit (when the occupant is fainted or trapped), the fire-fighting unit can be automatically activated by the sensing component to detect the slamming. 2. When the vehicle is spontaneously ignited (when the occupant is awake) The occupant senses to stop and stop the fire. The fire-fighting unit is manually activated. By spraying a large amount of fire-extinguishing materials to make the flammable engine room and fuel tank, the space air lacks oxygen and causes suffocation, and finally can not catch fire, or is about to catch fire. The message, such as smoke, burnt smell, etc., and the occupant's sensory judgment is often more effective than the sensing component sensing, then turn on the manual switch to extinguish the fire immediately. Therefore, if the fire can be effectively controlled before the vehicle is on fire, the probability of occupant casualties and vehicle damage can be greatly reduced, and the purpose of preventing the vehicle from being fired can be achieved.

Accordingly, in order to solve the fire problem of the existing vehicle, the inventors have intensively developed a preventive device for preventing a fire in the vehicle, thereby preventing the vehicle from catching fire, thereby reducing occupant casualties and reducing the damage of the vehicle. Summary of the invention
