Description

차량용 범퍼 빔 유닛{BUMPER BEAM UNIT FOR VEHICLE}Bumper Beam Unit for Vehicles {BUMPER BEAM UNIT FOR VEHICLE}

본 발명은 차량용 범퍼 빔 유닛에 관한 것으로서, 보다 상세하게는 차량의 충돌 시, 범퍼 빔의 양 단부 붕괴를 억제하여 충격흡수성능을 향상시키는 차량용 범퍼 빔 유닛에 관한 것이다.The present invention relates to a bumper beam unit for a vehicle, and more particularly, to a bumper beam unit for a vehicle that suppresses the collapse of both ends of the bumper beam when the vehicle collides, thereby improving shock absorption performance.

일반적으로 차량에서의 범퍼는 차량이 다른 차량이나 고정체와의 충돌 시, 그 충격을 흡수하여 승객의 안전을 도모하며, 동시에 차체의 변형을 최소화할 수 있도록 차체 전, 후방에 설치되는 완충유닛이다.In general, a bumper in a vehicle is a shock absorbing unit installed at the front and rear of a vehicle so that the vehicle absorbs the impact when the vehicle collides with another vehicle or a fixed body to promote the safety of the passenger and at the same time minimize the deformation of the vehicle body. .

이러한 범퍼는 차량의 전, 후방에 차폭 방향으로 배치되는 범퍼 빔이 크래쉬 박스를 통하여 차체측 사이드 멤버에 장착되고, 범퍼 빔의 전방에는 충격력을 흡수하는 에너지 업소버가 배치되며, 범퍼커버가 상기 범퍼 빔과 에너지 업소버를 감싸면서 설치된다. The bumper includes a bumper beam disposed in the vehicle width direction at the front and rear of the vehicle through a crash box to the side member of the vehicle body, and an energy absorber for absorbing the impact force is disposed at the front of the bumper beam, and the bumper cover includes the bumper beam. And is wrapped around the energy absorber.

도 1에 도시된 바와 같이, 상기한 범퍼 빔(101; 프론트 범퍼의 경우)은 후방 양측에 크래쉬 박스(103; 또는 스태이)가 체결된 상태로, 차체 측의 사이드 멤버에 조립된다. As illustrated in FIG. 1, the bumper beam 101 (in the case of the front bumper) is assembled to the side member on the vehicle body side with the crash box 103 (or stai) fastened to both rear sides thereof.

상기 범퍼 빔(101)은 상부 중앙에 강성 보강 및 충돌 시의 언더 라이딩 현상 등을 방지하기 위한 보강부재(105)가 설치되고, 일측방 내측에는 토잉 훅을 조립하기 위한 토잉 너트(107)가 설치된다. The bumper beam 101 is provided with a reinforcing member 105 in the upper center to prevent rigid reinforcement and an underriding phenomenon in the event of a collision, and a towing nut 107 for assembling a towing hook is installed inside one side. do.

그러나 종래의 범퍼 빔(101)은 차량의 옵셋 충돌 시, 토잉 너트(107)가 설치되지 않은 일측부(P)의 경우, 강성이 취약하여 범퍼 빔(101)이 쉽게 변형되는 단점이 있다. However, the conventional bumper beam 101 has a disadvantage in that, in the case of an offset collision of the vehicle, in the case of the one side P where the towing nut 107 is not installed, the bumper beam 101 is easily deformed due to the weak rigidity.

또한, 차량에 스티프너(미도시)가 설치된 경우, 옵셋 충돌에 의한 범퍼 빔의 단면 붕괴로 스티프너 브래킷(미도시)이 쉽게 파손되어 스티프너의 변형각(즉, 최초 스티프너의 위치에서 스티프너 브라켓의 변형에 의해 스티프너가 이동한 각을 말함)을 증가시키는 단점이 있다. In addition, when a stiffener (not shown) is installed in the vehicle, the stiffener bracket (not shown) is easily broken due to the cross-sectional collapse of the bumper beam due to the offset collision, so that the deformation angle of the stiffener (i.e., the deformation of the stiffener bracket at the position of the first stiffener) is prevented. By the stiffener is moved).

또한, 변형된 스티프너는 상대부품과의 간섭이 발생하여 차량의 손상을 가중시키는 단점이 있다. In addition, the deformed stiffener has a disadvantage in that interference with the counterpart causes damage to the vehicle.
