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 범퍼 빔에 충돌이 발생할 경우, 차량에 가해지는 충돌에너지를 분산시켜 범퍼 빔의 변형을 최소화시키는 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 minimizes deformation of the bumper beam by dispersing collision energy applied to the vehicle when a collision occurs in the bumper beam of the vehicle.

일반적으로 차량에서의 범퍼는 자동차가 다른 자동차나 고정체와의 충돌 시, 그 충격을 흡수하여 승차자의 안전을 도모하며, 동시에 차체의 변형을 최소화 할 수 있도록 자동차의 전, 후 단부에 배치되는 완충유닛이다.In general, a bumper in a vehicle absorbs an impact when a vehicle collides with another vehicle or a fixed body to promote the safety of the occupant, and at the same time, a shock absorber disposed at the front and rear ends of the vehicle to minimize deformation of the vehicle body. Unit.

도 1에서 도시한 바와 같이, 종래의 차량용 범퍼 빔 유닛은 차량의 전, 후방에서 차폭 방향으로 배치되는 범퍼 빔(100)의 후면 양측에 아웃터 플랜지(111), 인너 플랜지(113) 및 장착 플랜지(115)로 구성되는 스태이(110)를 통하여 차체에 장착된다. As illustrated in FIG. 1, a conventional vehicle bumper beam unit includes an outer flange 111, an inner flange 113, and a mounting flange on both rear sides of a bumper beam 100 arranged in a vehicle width direction from the front and rear of a vehicle. It is mounted to the vehicle body via a stair 110 composed of 115.

이러한 범퍼 빔(100)의 중앙부 후면에는 보강패널(120)가 장착되어 충돌 시, 발생되는 충돌 에너지를 흡수하게 된다.The reinforcement panel 120 is mounted at the rear of the central portion of the bumper beam 100 to absorb the collision energy generated during the collision.

그러나 종래의 차량용 범퍼 빔 유닛이 적용된 승용차량이 지상고가 높은 RV 차량과의 전방 충돌 시, 범퍼 빔의 중앙을 기준으로 상부에서 충돌이 이루어지게 되는 바, 범퍼 빔 전방 상부의 변형이 심하게 발생되며, 이로 인해 충격에너지를 흡수성능이 저감되는 문제점이 있다.However, when the conventional vehicle bumper beam unit is applied to the front of the bumper beam with a high ground clearance RV vehicle, the collision is made at the top relative to the center of the bumper beam, the deformation of the front of the bumper beam is severely generated. Due to the shock energy absorption performance is reduced.

즉, 충격에너지를 효과적으로 분산시키지 못하여 범퍼 빔의 충돌부위에서만 충격에너지가 흡수되어 하부에 비해 상부에서 더 큰 변형이 발생되며, 이로 인해 범퍼빔의 전체적인 변형량이 증가하는 문제점이 있다.That is, the impact energy is absorbed only at the impact portion of the bumper beam because it is not effectively dispersed, the larger deformation occurs at the top than the bottom, thereby increasing the overall amount of deformation of the bumper beam.

본 발명의 실시 예는 차량의 저속 충돌 사고 시, 범퍼 빔의 상부에 충돌이 가해질 경우, 충돌에너지를 범퍼 빔의 하부로 분산시켜 충돌흡수성능을 향상시키는 차량용 범퍼 빔 유닛을 제공하고자 한다.An embodiment of the present invention is to provide a bumper beam unit for a vehicle that improves the collision absorption performance by dispersing the collision energy to the lower portion of the bumper beam when a collision is applied to the upper portion of the bumper beam during a low-speed collision accident of the vehicle.

그리고, 상기 하측 용접단(33)은 인너 빔(23)의 내면 중앙부에 용접되고, 상기 연결부(35)는 상측 용접단(31)과 하측 용접단(33)을 일체로 연결하며, 이러한 연결부(35)는 인너 빔(23)의 상면과 평행하게 배치된다.In addition, the lower welding end 33 is welded to the inner central portion of the inner beam 23, and the connection part 35 integrally connects the upper welding end 31 and the lower welding end 33, and the connection part ( 35 is disposed in parallel with the upper surface of the inner beam 23.

따라서, 상기 차량용 범퍼 빔 유닛(1)은 차량의 저속 충돌 사고 시, 범퍼 빔(20)의 상부에 충돌이 가해지게 되면, 아웃터 빔(21)으로 충돌에너지가 전달되고, 그 전달된 충돌에너지는 아웃터 빔(21)의 상단과 인너 빔(23)의 상단 사이에 용접되어 있는 보강패널(30)의 상측 용접단(31)으로 전달된다.Therefore, in the vehicle bumper beam unit 1, when a collision is applied to the upper portion of the bumper beam 20 during a low speed collision accident of the vehicle, collision energy is transmitted to the outer beam 21, and the transmitted collision energy is The upper end of the outer beam 21 and the upper end of the inner beam 23 is transmitted to the upper welding end 31 of the reinforcement panel 30 is welded.

그리고, 상기 상측 용접단(31)으로 전달된 충돌에너지는 연결부(35)를 통해 인너 빔(23)의 내면 중앙부에 용접되어 있는 하측 용접단(33)으로 충돌에너지가 전달됨으로써, 충돌사고에 따른 차량의 손상을 최소화시킬 수 있다.In addition, the collision energy transmitted to the upper welding end 31 is transmitted to the lower welding end 33 welded to the inner central portion of the inner beam 23 through the connecting portion 35, thereby resulting in a collision accident. Damage to the vehicle can be minimized.

지금까지 설명한 바와 같이, 본 발명의 실시 예에 따른 차량용 범퍼 빔 유닛(1)은 차량의 저속 충돌 사고 시, 범퍼 빔(20)의 상부에 충돌이 가해질 경우, 충돌에너지를 흡수 및 범퍼 빔(20)의 하부로 충돌에너지를 분산시킴으로써, 차량의 손상을 최소화시켜 상품성을 향상시킬 수 있다.As described above, the vehicle bumper beam unit 1 according to an exemplary embodiment of the present invention absorbs collision energy and bumper beams 20 when a collision is applied to the upper part of the bumper beam 20 during a low speed collision accident of the vehicle. By dispersing the collision energy to the lower part of the), it is possible to minimize the damage of the vehicle to improve the merchandise.
