This invention relates to a vehicle collision protection device.

わせることが提案されている。 When a vehicle is involved in a collision, the collision causes a short circuit in the electrical circuit inside the vehicle, causing an overcurrent to flow through the circuit and overheating the circuit, causing gasoline to leak into the vehicle. often ignites and causes fires in vehicles. In order to prevent such accidents during collisions, a collision acceleration detector is installed to detect the impact force generated by the impact of the collision that occurs when a vehicle collides as collision acceleration.
It has been proposed to convert this detection output into a mechanical signal or an electrical signal, and to inject extinguishing agent into the vehicle or to cut off the battery power supply based on this converted signal.
しかしこの提案されている方式では衝突加速度

要があるため、この伝送線に雑音信号が侵入して
誤動作を誘起するおそれもある。 However, in this proposed method, the detection sensitivity of the detection device that detects the collision acceleration is partial, and unless a large number of detection devices are installed, the detection area will be limited, and depending on the installation location, vibration energy may be transmitted halfway. In some cases, it is attenuated and cannot be detected. For this reason, it is necessary to select the installation position when installing it on the vehicle, and it is also necessary to set the collision acceleration detector so that it does not operate when a sudden braking operation of the brake system does not result in a collision. However, there are also disadvantages in that the structure becomes complicated and adjustment man-hours are required when installing it. Furthermore, in the case of a system that operates using electrical signals, it is necessary to install a transmission line inside the vehicle, so there is a risk that noise signals may enter the transmission line and induce malfunction.

To provide a collision protection device for a vehicle that does not require adjustment work and can operate with high sensitivity in response to the occurrence of a collision to cut off the supply of power from a battery power source to the vehicle.
