The present invention relates to a forward collision shock absorber of a vehicle, which comprises: a plate spring which is formed in the longitudinal direction and bent into an arcuate shape; bearings which are attached to both ends of the plate spring; a rail shaft which guides the bearing in a sliding manner; and a mount which fixes the rail shaft to a vehicle body and is attached or detached as occasion demands. When an impact occurs due to a forward collision of the vehicle, the plate spring is pushed linearly while attenuating the impact. When the plate spring reaches the limit point, a shear pin is cut so that the bearing slides along the rail shaft, thereby attenuating the impact. The shock absorber enhances workability and productivity since being simple in structure and easily attached and detached, and suppresses an engine compartment from pushing into an interior space by doubly attenuating and mitigating impact generated due to a forward collision of a vehicle, thereby providing excellent safety by protecting a driver and passengers.

    본 발명은 차량의 전방추돌 충격완화 장치에 관한 것으로서, 길이방향으로 형성되어 원호 형상으로 휘어지는 판스프링과 판스프링의 양쪽 끝에 결합되는 베어링, 베어링이 슬라이딩하게 가이드하는 레일축, 레일축을 차체에 고정하고 필요에 따라 탈장착하는 마운트로 구성되며, 차량의 전방 추돌로 발생하는 충격을 판스프링이 감쇠하면서 직선에 가깝게 밀려나서 한계점에 도달하면 시어핀(shear pin)이 절단되어 베어링이 레일축을 따라 슬라이딩하여 충격을 감쇠하는 것을 특징으로 한다. 이에 따라 구조가 간단하고 필요에 따라 탈장착이 용이해 작업성과 생산성이 향상되며, 차량의 전방 추돌로 인하여 발생하는 충격을 감쇠하고 완화시켜 실내공간으로 충격과 함께 밀려 들어오는 엔진룸을 억제하여 운전자와 탑승자를 안전하게 보호할수 있어 안전성이 향상된다.
