KR960040869A - Shock Absorber of Automobile Bumper - Google Patents

Abstract

The present invention relates to a shock absorber of an automobile bumper, and in particular, to significantly absorb and attenuate primary shocks caused by contact or collision of a vehicle to prevent accidents of the occupants, and at the same time to deform components of the vehicle body and engine, In order to prevent breakage, the bumper 11 and the bumper 11 including the reinforcement 13 bonded to the facer 12, the shock absorber 15 embedded between the facer 12 and the reinforcement 13. Removes the usual bumper stays spaced apart from the vehicle body 16 at regular intervals, and a plurality of pneumatic cylinders 17, pneumatic cylinders 17 and a reinforcing member 13 interconnected to the space, Spherical valve 24a so as to be opened and closed by a cushioning spring 23 provided between the pneumatic cylinder 17 and the reinforcement 13 of the bumper 11 and the air expansion pressure and the suction part pressure in the air chamber 17a of the pneumatic cylinder 17. ) Is made of a rubber material throttle valve (24) When a certain amount of shock is generated from the front and the unspecified direction, the bumper 11 is temporarily compressed and retracted and displaced, and at the same time, the shock is absorbed and alleviated. When the shock is released, the displaced bumper 11 returns to its original position, When the shock absorber of the bumper 11 is more than km, the compression progression of the piston 18 is rapidly made by the throttle valve 24, and when the shock is released, the return of the bumper 11 is gradually made.

Claims (6)

Pneumatic cylinders installed on the front and corners between the bumper and the body to displace the bumper during vehicle collision to absorb and alleviate the primary shock, and elasticity between the pneumatic cylinder and the bumper to return the displaced bumper to its original position when the impact is extinguished. Installed in the shock absorber of the vehicle bumper, characterized in that consisting of a shock absorbing spring to firmly support the bumper in the normal state. The spherical valve of claim 1, wherein the pneumatic cylinder is configured to reduce the pressure of the air chamber during a vehicle collision to quickly displace the bumper and to absorb the shock and to gradually return the bumper by the negative pressure when the impact is extinguished. The shock absorber of the automobile bumper, characterized in that the throttle valve is opened and closed. The shock absorber of claim 1, wherein the bumper and the pneumatic cylinder are connected to each other by a joint joint to three-dimensionally absorb a shock applied from an unspecified direction. According to claim 1, Between the bumper and the pneumatic cylinder, a silicone rubber with a primary buffer spring is inserted to absorb the shock of the relatively small bumper, and to absorb the impact of the relatively large bumper of the pneumatic cylinder A shock absorbing device for an automobile bumper, wherein a secondary shock absorbing spring having a force greater than that of the primary shock absorbing spring is installed in the air chamber. The shock absorbing device of claim 1 or 4, wherein a corner between the bumper and the vehicle body is installed only by a spring. The shock absorbing device of claim 1, wherein the pneumatic cylinder has a cushioning material attached to front and rear surfaces of the piston. ※ Note: This is to be disclosed by the original application.
