Abstract
The utility model belongs to the spare parts of the vehicle control system. A concave box that is equipped with a deceleration umbrella is at the tail end of the top shell. Four elastic ropes and four guide balls are distributed symmetrically on the edges of the umbrella cover. The ropes and the balls are respectively fixed inside the concave box and at the front end. The four guide balls are installed to the four launchers inside the concave box. Wind-driven generators are positioned at the front of the top shell, which will switch on the electromagnet, open the cover board, and enable the four sets of the high tension igniting circuit to work simultaneously, through the comparison of the control signals of the circuit and the emergency brake signals. Four sets of high pressure ignition circuits work simultaneously and the high tension spark is fired inside the canister launcher and the guiding balls are pushed out of the launcher and then open the drogue parachute. The utility model detects the relative wind speed during driving via the wind generator. When the wind speed is more than 70 to 110 kilometers per hour, and the car speed is more than 70 to 110 kilometers per hour, an emergency brake should be activated. The drogue parachute inside of the convex box is opened automatically, which decreases the brake distance of the high speed driving car, thus preventing or reducing the damage caused to either the car or people.
