The present invention relates to a bumper back beam assembly for a vehicle with a double plate structure capable of increasing a shock absorbing performance by changing a bumper back beam structure from a conventional single plate structure to a double plate structure with two bonded plates to increase section modulus, and reducing costs and weight of a vehicle component by using a back beam material of the double plate structure as a long fiber thermoplastic (LFT) material. The bumper back beam assembly for a vehicle installed at the front or a rear of a vehicle (10) comprises: a bumper back beam (110) including a shock absorbing space (S) therein by bonding at least two plates; and a crash box (120) interposed between both sides of the bumper back beam (110) and the vehicle body (1) to absorb an impact when the vehicle is bumped.

    본 발명은 범퍼 백빔 구조를 기존의 단판에서 두 개의 판을 융착한 복판 구조로 변경해줌으로써 단면계수를 높여 충격 흡수 성능을 향상시킬 수 있으며, 복판 구조의 백빔 재질을 장섬유 복합소재(LFT, Long Fiber Thermoplastic)로 사용함으로써 차량 부품의 경량화 및 원가를 절감할 수 있도록 한 복판구조를 갖는 차량용 범퍼 백빔 조립체에 관한 것이다. 이를 실현하기 위한 본 발명은, 차체(1)의 전면이나 후면 중심부에 설치되는 차량용 범퍼 백빔 조립체에 있어서, 적어도 두 개의 판을 융착시켜 내부에 충격흡수공간(S)을 마련해주는 범퍼 백빔(110); 및 상기 범퍼 백빔(110)의 양측과 상기 차체(1) 사이에 개재되어 차량의 충돌 시 충격을 완충시켜주는 크래시 박스(120);를 포함한다.
