When the car is driving, when the accident occurs, the driver is nervous, and the door is slammed as a brake. Because the force is too large, the switch K at the lowest part of the throttle is often closed. The control circuit was designed by slamming the throttle to close K.
As shown, 555 and R1, G1, etc. form a trigger circuit. Normally, 555 is in the set state, 3 feet are high, and J does not move. J1-1 and J1-2 are in the off state. When the throttle is mistaken, J is closed, 6 feet is high, so that 555 is reset, J is sucked, JI-1, Jl-2 is closed, and the electromagnetic valve DF is energized, then the high pressure gas is supplied to the brake mechanism through the DF. Brake the car to prevent accidents.
