차량용 범퍼빔 유닛{AUTOMOTIVE BUMPER BEAM UNIT}Bumper Beam Unit for Vehicles {AUTOMOTIVE BUMPER BEAM UNIT}

본 발명은 차량용 범퍼빔 유닛에 관한 것으로서, 보다 상세하게는 롤 포밍 성형되는 범퍼빔의 양단부에 프레스 성형되는 별도의 사이드 브라켓을 부착하여 충격흡수성능이 우수하고, 구조적으로 안정된 차량용 범퍼빔 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 having excellent shock absorption performance and structurally stable by attaching separate side brackets which are press-formed at both ends of the bumper beam to be roll-formed. will be.

일반적으로 차량에서의 범퍼는 자동차가 다른 자동차나 고정체와의 충돌시, 그 충격을 흡수하여 승차자의 안전을 도모하며, 동시에 차체의 변형을 최소화 할 수 있도록 자동차의 전,후 단부의 소정 부위에 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 predetermined portion of the front and rear ends of the vehicle can be minimized to minimize deformation of the vehicle body. The buffer unit is arranged.

도 1에서 도시한 바와 같이, 상기한 범퍼(100)는 차량의 전,후방에서 차폭 방향으로 배치되는 범퍼빔(101)의 후방 양측에 스테이(103)가 장착되어 차체측 사이드 멤버(111)에 고정되는 범퍼빔 유닛(105)과, 상기 범퍼빔(101)의 전방에 배치되어 충격력을 흡수하는 에너지 업소버(107), 그리고 상기 범퍼빔(101)과 에너지 업소버(107)를 감싸는 범퍼 커버(109)로 이루어진다.As shown in FIG. 1, the bumper 100 has a stay 103 mounted at both rear sides of the bumper beam 101 arranged in the vehicle width direction from the front and rear of the vehicle, and thus the bumper 100 is mounted on the vehicle side side member 111. A fixed bumper beam unit 105, an energy absorber 107 disposed in front of the bumper beam 101 to absorb impact force, and a bumper cover 109 surrounding the bumper beam 101 and the energy absorber 107. )

여기서, 상기한 종래의 범퍼빔 유닛(105)은, 도 2에서 도시한 바와 같이, 롤 포밍 성형되는 상기 범퍼빔(101)은 범퍼 커버(109)의 양단 내측과 간섭되는 것을 피하고, 그 설계 자유도를 높이기 위하여 기존의 고장력 강판의 롤 포밍 성형 범퍼 빔(101)의 최대 성형곡률 한계까지 그 양단부를 성형하여 적용된다. Here, in the conventional bumper beam unit 105, as shown in FIG. 2, the bumper beam 101 that is roll-formed is avoided from interfering with both ends of the bumper cover 109, and its design freedom In order to increase the shape of both ends of the roll forming molding bumper beam 101 of the existing high tensile steel sheet up to the maximum forming curvature limit is applied.

그러나 상기한 종래의 범퍼빔(101)은 그 양단부의 최대 성형곡률 한계까지 곡률 성형하여도 범퍼커버(109)의 양단부 내측을 전체적으로 지지하기는 간섭의 문제점이 있으며, 이러한 상태로, 차량의 옵셋 충돌 시, 그 충돌 에너지가 범퍼빔(101) 전체로 분산 흡수되지 못하고, 상기 범퍼커버(109)를 완전히 파손시키면서 범퍼빔(101)의 충격흡수성능을 저하시키며, 구조적으로도 안정적이지 못한 등의 문제점이 있다.However, the conventional bumper beam 101 has a problem of interference to support the inside of both ends of the bumper cover 109 even when curvature is formed up to the maximum molding curvature limit of both ends thereof. When the collision energy is not dispersed and absorbed into the entire bumper beam 101, the shock absorbing performance of the bumper beam 101 is degraded while the bumper cover 109 is completely damaged, and the structure is not stable. There is this.

또한, 이는 차량 사고 시, 승객 안전을 저해하는 요인이 되며, 사고 수리비용을 과다하게 하는 요인이 된다.In addition, this is a factor that impairs the safety of passengers in the event of a vehicle accident, and becomes a factor that causes excessive accident repair costs.

따라서 본 발명은 상기한 바와 같은 종래의 문제점들을 해소하기 위하여 발명된 것으로, 본 발명이 해결하고자 하는 과제는 롤 포밍 성형되는 범퍼빔의 양단부에 프레스 성형되는 별도의 사이드 브라켓을 부착하여 범퍼커버 양단과의 설계 자유도를 확보함과 동시에, 옵셋 충돌 시에는 범퍼커버로부터 전달되는 충돌 에너지를 범퍼빔 전체로 분산 흡수하도록 충돌 에너지 흡수구간을 더욱 넓게 확보함으로써 충격흡수성능이 우수하고, 구조적으로 안정된 차량용 범퍼빔 유닛을 제공하는 것이다. Therefore, the present invention has been invented to solve the conventional problems as described above, the problem to be solved by the present invention is to attach a separate side bracket press-formed at both ends of the bumper beam to be roll-formed and the bumper cover both ends and In addition to securing design freedom, the bumper beam has excellent shock absorption performance and structurally stable bumper beams by securing a wider collision energy absorption section to disperse and absorb collision energy transmitted from the bumper cover to the entire bumper beam during offset collision.

It is comprised so that the bumper beam 1 may be fixed to a vehicle body side side member (not shown).

이러한 상기 범퍼빔(1)의 양단부에는 각각 사이드 브라켓(5)이 끼워진 상태 로, 도 5와 도 6에서 도시한 바와 같이, 상기 범퍼빔(1)에 그 내측 단부면이 용접(WP1)되어 고정된다.Side brackets 5 are fitted to both ends of the bumper beams 1, respectively, and as shown in FIGS. 5 and 6, inner end surfaces of the bumper beams 1 are welded (WP1) and fixed to the bumper beams 1. do.

상기 사이드 브라켓(5)은, 도 5에서 도시한 바와 같이, 그 외측 선단의 폭(W1)이 내측 단부의 폭(W2)보다 좁아지도록 형성되며, 상기 범퍼빔(1)의 배면에 용접되는 인너 브라켓(9)과 상기 범퍼빔(1)의 전면에 용접되는 아웃터 브라켓(7)으로 이루어진다.As shown in FIG. 5, the side bracket 5 is formed such that the width W1 of the outer end thereof is narrower than the width W2 of the inner end, and is welded to the rear surface of the bumper beam 1. It consists of an outer bracket 7 welded to the front surface of the bracket 9 and the bumper beam 1.

즉, 상기 아웃터 브라켓(7)은, 도 6 내지 도 10에서 도시한 바와 같이, 전체적으로 "??" 자 형상으로 형성되며, 상기 인너 브라켓(9)은 상기 아웃터 브라켓(7)의 길이방향 상하 단부에 외측으로 끼워져 CO2 용접(WP2)에 의해 고정된다.That is, the outer bracket 7, as shown in Figures 6 to 10, as a whole "??" It is formed in the shape of a child, and the inner bracket 9 is fitted to the outside in the longitudinal upper and lower ends of the outer bracket 7 is fixed by the CO2 welding (WP2).

여기서, 상기 아웃터 브라켓(7)은, 도 10에서 도시한 바와 같이, 그 외측 선단 하부에 강성 보강을 위하여 내측으로 단차진 단차면(11)을 형성하여 구성된다.Here, as shown in FIG. 10, the outer bracket 7 is formed by forming a stepped surface 11 stepped inward for rigid reinforcement under the outer front end thereof.

또한, 상기 인너 브라켓(9)과 아웃터 브라켓(7)은 상기 범퍼빔(1)의 양 선단에 대응하는 부분에서 외측으로 확장되어 내부에 공간부(S)를 형성하도록 확장부(13)를 갖는데, 상기 확장부(13)는 인너 브라켓(9)과 아웃터 브라켓(7)의 둘레를 따라 일정한 형상으로 형성되어 범퍼빔(1)의 단부 컷팅 시, 발생되는 치수 산포를 흡수하게 된다. In addition, the inner bracket 9 and the outer bracket 7 have an extended portion 13 to extend outward from portions corresponding to both ends of the bumper beam 1 to form a space S therein. The expansion part 13 is formed in a predetermined shape along the circumferences of the inner bracket 9 and the outer bracket 7 to absorb the dimensional dispersion generated when the end portion of the bumper beam 1 is cut.

따라서 상기한 바와 같은 구성을 갖는 차량용 범퍼빔 유닛은, 롤 포밍 성형되는 범퍼빔(1)의 양단부에 인너 브라켓(9)과 아웃터 브라켓(7)으로 프레스 성형되는 별도의 사이드 브라켓(5)을 용접하여 범퍼커버(미도시) 양단 내측과 설계 자유도를 확보함과 동시에, 옵셋 충돌 시에는 범퍼커버로부터 전달되는 충돌 에너지를 범퍼빔(1) 전체로 분산 흡수하도록 충돌 에너지 흡수구간을 더욱 넓게 확보함으로써 충격흡수성능을 향상시키고, 구조적으로 안정성을 갖는다.Therefore, in the vehicle bumper beam unit having the above-described configuration, the separate side brackets 5 which are press-molded by the inner bracket 9 and the outer bracket 7 are welded to both ends of the bumper beam 1 to be roll-formed. By securing the inside of both ends of the bumper cover (not shown) and the design degree of freedom, and at the time of offset collision, the impact energy absorption section is further secured so that the collision energy transmitted from the bumper cover is distributed and absorbed to the entire bumper beam 1. It improves absorption performance and has structural stability.

그리고 상기한 사이드 브라켓(5)은 범퍼빔(1)의 측면 충격흡수능력을 배가하여 차량 사고 시, 승객 안전 도모 및 사고 수리비용 절감의 이점을 갖는다.In addition, the side bracket 5 doubles the side shock absorbing capacity of the bumper beam 1, and thus has an advantage of improving passenger safety and reducing accident repair cost in a vehicle accident.
