The present invention relates to a shock absorbing unit arranged in an inner space in which an outer panel and an inner panel are formed, comprising: a reinforcing portion made of a composite material, having a panel shape and connected to the inner panel at both end portions thereof, dividing the inner space into a separate space of the outer panel side and a division space of the inner panel side, and having a coupling protrusion protruding toward the inner panel on the inner surface thereof; and a shock absorbing portion made of a composite material, having a coupling groove accommodating the coupling protrusion at one side thereof to be connected with the reinforcing portion within the division space, and supported by the inner panel by being connected to the inner surface of the inner panel at the other side thereof. An object of the present invention is to provide the shock absorbing unit capable of increasing coupling force between the coupling groove and the coupling protrusion via coupling and effectively absorbing shock energy.
아우터패널과 이너패널이 형성하는 내부공간에 배치되는 충격흡수 유닛으로서, 패널 형상으로서 양단부가 이너패널과 연결되어 내부공간을 아우터패널 측의 이격공간과 이너패널 측의 구획공간으로 구분하며, 내면에는 이너패널을 향해 돌출되는 결합돌기가 형성된 복합재 재질의 보강부; 및 일측에는 결합돌기를 수용하는 결합홈이 형성되어 구획공간 내에서 보강부와 연결되고, 타측은 이너패널 내면에 연결되어 이너패널에 의해 지지되는 복합재 재질의 충격흡수부;를 포함하는 충격흡수 유닛이 소개된다.
