【Example】

 The electric disconnection safety device for a vehicle according to the present invention uses a battery provided in the vehicle as the power source 10. The safety device 1 includes a normally closed electromagnetic valve 20 and a valve control circuit 30, which is connected in series with the electromagnetic valve to control its opening and closing. The electromagnetic valve 20 and the valve control circuit 30 are installed and installed in one box.

The electromagnetic valve and the valve control circuit are connected by connecting the cathode terminal 11 of the battery 10 and one end of the electromagnetic valve with the electric wire 12, and connecting the other end of the electromagnetic valve to one end of the valve control circuit 30. Further, the anode terminal 14 of the battery 10 is connected to one electric wire 15, the other end of the valve control circuit 30 is connected to the electric wire 13, and the original electric circuit of the automobile is connected in series between the electric wires 13 and 15. To do. Since the electromagnetic valve 20 is of a normally closed type, the electric wires 12 and 13 are normally connected to each other, and the electric power of the power source 10 is connected to the electric wires. However, if the valve control circuit 30 receives a signal coming from the sensor 40 described later, the valve control circuit 30 is activated to open the electromagnetic valve 20, and the electric wires 12 and 13 are cut off. Loses electricity. Therefore, if there is a short circuit somewhere in the original electric circuit of the car, the short circuit will disappear and it will be safe.

In addition, a plurality of sensors 40 are fixedly installed on the front and rear bumpers of the vehicle, and are connected in parallel to the valve control circuit 30. The sensor 40 is practically the same as the operation of a kind of switch, and there are two types, a normally open type as shown in FIG. 3 (A) and a normally closed type as shown in FIG. 3 (B). There are various types such as magnetic type and photosensitive type. If the sensor 40 is of the normally open type, if the vehicle is shocked in an accident, the normally open contact point is closed and the sensor 40 sends a signal to the valve control circuit 30. The valve control circuit is then activated, causing the normally closed contact point of the electromagnetic valve 20 to open and the power source 10 being de-energized. Therefore, short circuits are prevented. Also, if the sensor 40 is of the normally closed type, when a shock is detected, it is opened in the opposite direction, and a signal is similarly sent to the valve control circuit 30, so that the electromagnetic valve 20 is also opened. The power of the power supply 10 is cut off.

The valve control circuit described above can be designed in various ways. However, according to the present invention, after connecting the switch 31, the relay 32, and the transistor 33 in combination as shown in FIG. It is connected in parallel with this. So, if any of the sensors 40 sends a signal, the transistor 33 is activated by that signal, so that the relay 32 is then actuated and then actuates the switch 31 to change its state. For example, when the switch 31 is originally of the normally open type and the power source is not connected, the switch 31 is closed and the power source 10 is connected. When the switch 31 is normally closed and the power source 10 is open, the power source 10 is disconnected.

The principle of the present invention is to change the connection state of the switch 31, change the connection state of the electromagnetic valve 20, and change the connection state of the power supply 10. If at least one sensor 40 senses it at the moment when a vehicle equipped with the safety device 1 of the present invention is shocked in an accident, that sensor 40 sends a signal to the valve control circuit 30, and this circuit The connection state of the switch 31 in 30 is changed, then the connection state of the electromagnetic valve 20 is changed, and the power supply 10 can be cut off to ensure safety.

When one ON switch 50 is further added to the safety device 1, and when the power source 10 is turned off by the action of the safety device 1 due to an accident in the vehicle, and there is no fire in the vehicle. In addition, if the ON switch is operated, the power supply 10 is also connected to the electric circuit of the car, and the car can be started again. There are two types of installation methods of the ON switch 50. One of them is connected between the electric wires 12 and 13 of the safety device 1 in parallel with the electromagnetic valve 20 and fixed on the box 120. Normally, this ON switch 50 does not conduct electricity when it is open. Then, when the electromagnetic valve 20 is changed from the normally closed state to the opened state, that is, when the electromagnetic switch 20 is turned off, the ON switch 50 is closed, so that the electric wires 12 and 13 are connected again, and the power source is turned on. 10 electricity is re-conducted. As another kind of installation method of the ON switch 50, the ON switch 50 is installed at an appropriate place in the driver's seat and connected in parallel with the electromagnetic valve 20 as described above. The addition of the ON switch 50 is determined by the user's need. Further, there are various structures of the ON switch 50.

When a safety switch 1 is additionally provided with an OFF switch 60, the power source 10 is cut off for an emergency in the outside when the automobile has not yet turned off the power source 10 by the safety device 1. By operating the OFF switch 60, the power supply 10 can be cut off. The structure of the OF F switch is similar to that of the sensor 40, and it is fixed at an appropriate place in the driver's seat, and in case of a car fire due to an urgent short circuit of unknown cause, or the electric wire becomes old. If the driver manually turns off the OFF switch 60 in the event of a short circuit, the valve control circuit 30 is activated to open the electromagnetic valve 20 and the power source 10 is cut off, as in the case of the operation of the sensor 40. It is a known fact that an automobile made by an automobile company had several accidents in which a gauge plate caused a fire. In such a situation, the OFF switch 60 is just useful. The OFF switch 60 can also be used for the anti-theft function of the vehicle, and if the vehicle is not used for a long period of time and the power source 10 is turned off by the light, the OFF switch 60 acts and the vehicle cannot be started.
