【考案の詳細な説明】
産業上の利用分野
本考案は自動車の火災を防止する装置に係り、
とくに自動車に実装された電装品からガソリン等
の燃料に引火することを防止する装置に関する。[Detailed description of the invention] Industrial application field This invention relates to a device for preventing fires in automobiles.
In particular, the present invention relates to a device that prevents fuel such as gasoline from igniting from electrical components installed in an automobile.

症を負つたりすることが少なくなつてきた。BACKGROUND OF THE INVENTION In recent years, automobile safety has become a major issue, and seat belts, bumpers, vehicle body structures, etc. have been improved, and automobile safety has been increased. As a result, the number of deaths and serious injuries caused by collisions and other accidents has decreased.

多くなつてきた。Problems that the invention aims to solve However, when a car accident such as a collision occurs,
Fuel (gasoline, etc.) from the fuel tank or fuel pipe
may leak. If it just leaks, there is little danger, but if it ignites, the fuel is highly combustible, so it spreads quickly and violently. For this reason, even if no one is killed or injured in an accident such as a collision, a car may catch fire or cause severe burns. It is thought that ignition of fuel mainly occurs from the electrical system of an automobile, but in conventional automobiles, no special measures have been taken to prevent ignition of fuel from the electrical system. For this reason, more and more people are dying or injured due to car fires rather than accidents themselves.

Fuyuzu Fu is connected. Next, to briefly explain the fuel system of an automobile, fuel in a fuel tank 61 is sent to an engine 64 through a fuel pipe 65 by a fuel pump 62. A pressure sensor 63 is provided in the fuel pipe 65 . The output of the pressure sensor 63 is connected to one input terminal of a comparator Cp, and the other input terminal of the comparator Cp is connected to a reference power source. The electrical component side terminal of the fuse Fu is grounded via the relay contact S of the relay 66, and the coil L of the relay 66 is connected to the power source via the transistor Tr, which is controlled to be conductive or non-conductive by the output of the comparator Cp. is supplied.

る。 Next, the operation will be explained. When fuel leaks, the pressure inside the fuel pipe 65 decreases. Pressure sensor 63
The output of the comparator Cp is compared with the reference voltage V, and the output of the comparator Cp makes the transistor Tr conductive to cause current to flow through the relay coil L. As a result, the relay contact S closes, creating a short-circuit state and disconnecting the fuse Fu, cutting off the power supply to the electrical components and preventing a car fire.
