본 발명은 다단계 에너지흡수장치에 관한 것으로서, 더욱 상세하게는철도차량이나 충격을 해소하기 위한 구조물에 설치되어 한번에 강한 충격이 가해지더라도 안정적으로 충격을 해소할 수 있을 뿐만 아니라, 여러 단계에 걸쳐 충격을 흡수하여 안정적으로 충격을 완화할 수 있도록 하는 다단계 에너지흡수장치에 관한 것이다. 상기한 목적을 달성하기 위한 본 발명은 구조물에 설치되는 2차완충부와, 상기 2차완충부의 전부에 설치되는 1차완충부를 포함하되, 충격 발생 시 1차완충부 및 2차완충부가 순차적으로 충격을 해소하도록 하는 것을 특징으로 한다.

    The present invention relates to a multi-stage energy absorption device, and more particularly to the multi-stage energy absorption device, which is installed in a railway vehicle or a structure for relieving shock, thereby capable of relieving shock stably even if a strong shock is applied at once, and also absorbing shocks in several stages to stably alleviate shocks. The present invention for achieving the above objectives includes: a secondary buffer part installed in the structure; ad a primary buffer part installed in all of the secondary buffer part. When a shock occurs, the primary buffer part and the secondary buffer part sequentially relieve the shock.
