Claims

[Claim for Utility Model Registration] A device that can increase the obstruction distance when a car collides, in particular a sliding rail that can push the bumper forward and backward of the body using air compression, and has a device that fixes it to the chassis. , a cushion spring mounted on a sliding rail, a sliding block with a through hole through which the sliding rail passes, a cylinder connected to the sliding block, having a piston and a piston rod therein, and filled with air under the control of an air cylinder; A set of control devices using a multi-control switch, connected to the piston rod, includes a solenoid valve that controls the air pressure entering the cylinder, a compressor that fills the normal air cylinder with air, and a safety valve that prevents the cylinder from bursting. A bumper base, a bumper in which a hanger equipped with a cushion spring is hung from the bumper base, a flake spring is fixed to the bumper base, and the hanger and the flake spring are fitted between the bumper base and the bumper base. , When the car suddenly brakes after setting the speed and distance, the bumper is pushed out in the front and back direction of the body by the pressure of the cylinder, increasing the cushioning distance, and each spring is used to reduce the speed and reduce the speed of the passenger. An air-retractable automobile bumper characterized by reducing injury.
