A vehicle crash box is disclosed. According to an embodiment of the present invention, the vehicle crash box is bonded to both sides of a rear bumper beam and connects the bumper beam and a side member. A first plate and a second plate, which are bent in multiple stages, form a coupling member having a front side and a rear side horizontally formed, while forming a closed section at the center by being coupled to each other through a cutting line formed symmetrically on each cross section. The horizontally formed surfaces of the plurality of coupling members are interconnected to each other by welding to be joined to both sides at the rear of the bumper beam.

    차량용 크래쉬 박스가 개시된다. 본 발명의 일 실시 예에 따른 차량용 크래쉬 박스는 범퍼 빔의 후방 양측에 접합되어 상기 범퍼 빔과 사이드 멤버를 연결하는 차량용 크래쉬 박스에 있어서, 다단으로 절곡된 제1 판재와 제2 판재가 각 단면상에 대칭되게 형성된 절개라인을 통해 상호 결합되어 중앙부에 폐단면을 이룬 상태로, 전방측과 후방측이 수평하게 형성되는 결합부재를 형성하고, 복수개의 상기 결합부재의 수평하게 형성된 면을 맞대어 용접을 통해 상호 연결하여 상기 범퍼 빔의 후방에 양측에 접합한다.
