And a rib (21) formed in the same direction as the projecting portion (20) in the longitudinal direction inside the projecting portion (20), characterized in that the projecting portion 20) by forming a reinforcing portion (30) having a predetermined gentle inclination in the longitudinal direction of the inner side of the center portion of the impact beam (20) and increasing the thickness of the cross section toward the center, thereby increasing the stiffness of the central portion of the impact beam And at the same time the manufacturing cost is not affected.
Description
본 발명은 차량의 리어 범퍼(Reer Bumper)를 구성하는 임팩트 빔(impact Beam)에 관한 것으로, 특히 차량의 리어 범퍼 임팩트 빔이 미국의 IIHS(Insurance Institute of Highway Safety)리어 폴(Rear Pole)5MPH 규격을 만족할 수 있도록 강성을 개선한 차량의 리어 범퍼 임팩트 빔에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an impact beam constituting a rear bumper of a vehicle, and more particularly to an impact beam of a rear bumper impact beam of a vehicle, To the rear bumper impact beam of the vehicle.
미국의 IIHS규격에서는 차량의 안전을 위하여(직경 18인치의) 폴(Pole0에 차량을 5마일/시간(M/HR)의 속도로 후진하여 폴(Pole)에 리어 범퍼의 중앙을 충돌시켰을 때 차체 부분이 손상되지 않아야 할 것을 규정하고 있다.In the US IIHS standard, when the center of a rear bumper is collided with a pole (backward at a speed of 5 miles / hour (M / HR)) to a pole (Pole0) The parts should not be damaged.
실제 리어 범퍼는 중앙부에 벤딩모멘트가 가장 크게 걸리므로 충돌시 그 중앙부의 단면부가 가장 취약하여 임팩트 빔이 충격력을 흡수하지 못하고 그 영향이 차체에 미칠 수 있다.Since the actual rear bumper takes the greatest bending moment at the center part, the cross-section at the center of the impact is the weakest, so that the impact beam can not absorb the impact force, and the impact may be on the vehicle body.
일반적으로, 차량의 리어 범퍼는 차체이 롱지튜디널부재에 결합되는 스테이와, 상기 스테이에 연결되어 차량의 충돌시 에너지를 흡수하여 차체를 보호하는 리어범퍼 임팩트 빔과, 리어범퍼의 외관을 미려하기 하기 위하여 상기 임팩트 빔의 외측에 결합되는 패시아로 이루어져 있다.Generally, a rear bumper of a vehicle is provided with a stay coupled to a long body member of a vehicle body, a rear bumper impact beam connected to the stay to absorb energy when the vehicle collides with the vehicle to protect the vehicle body, And is coupled to the outside of the impact beam.
상기한 임팩트 빔은 종래에는 제1도에 도시되어 있는 바와 같이, 전면에 걸쳐 소정의 폭과 길이로 앞으로 돌출되어 있는 돌출부(20)와, 상기 돌출부(20)의 내측 길이 방향으로 상기 돌출부(20)와 동일체로 형성되어 있는 리브(21)로 구성되어 있고, 제1도의 중앙부 일부횡단면도에 도시되어 있는 바와 같이 임팩트 빔 전체단면의 두께가 일정하게 대략 5mm 정도로 되어 있으며 충돌시 충격을 흡수할 수 있는 가로면(25)이 3개가 된다.As shown in FIG. 1, the impact beam has a protruding portion 20 protruding forward with a predetermined width and length over the entire surface, and a protruding portion 20 protruding from the protruding portion 20 in the inner longitudinal direction of the protruding portion 20 As shown in a partial cross-sectional view of the center part of FIG. 1, the thickness of the whole cross section of the impact beam is constantly about 5 mm, and the impact can be absorbed by the ribs 21 Three transverse faces 25 are formed.
또한, 종래의 또 다른 임팩트 빔은 제2도에 도시되어 있는 바와 같이, 전면에 걸쳐 소정의 폭과 길이로 앞으로 돌출되어 있는 돌출부A(22)와, 상기 돌출부A(22)의 하측으로 일정거리 이격되고 상기 돌출부A(22)와 연속하여 동일체로 형성된 돌출부B(23)로 구성되어 있다. 제2도의 중앙부 일부횡단면도에 도시되어 있는 바와 같이 임팩트 빔 전체단면의 두께가 일정하게 대략 5mm 정도로 되어 있으며 충돌시 충격을 흡수할 수 있는 가로면(25)이 4개가 된다.As shown in FIG. 2, another conventional impact beam includes a protruding portion A 22 protruding forward with a predetermined width and length over the entire surface, and a protruding portion A 22 protruding downward from the protruding portion A 22 at a predetermined distance And a protruding portion B (23) which is spaced apart from the protruding portion A (22) and formed in the same body as the protruding portion A (22). As shown in a partial cross-sectional view of the center part of FIG. 2, the thickness of the entire cross section of the impact beam is constantly about 5 mm, and four transverse surfaces 25 capable of absorbing the impact at the time of collision become four.
종래의 임팩트 빔에서 충격흡수면이 3개인 것보다 충격흡수면이 4개인 것이 강성이나 강도의 측면에서는 우수하나 전체 무게 대비 성능이 충격흡수면이 3개인 것이 더 우수하므로 원가와 강성의 측면을 동시에 고려하여 일반적으로 충격흡수면이 3In the conventional impact beam, four impact absorbing surfaces are superior to three impact absorbing surfaces in terms of stiffness and strength, but three impact absorbing surfaces are better than the conventional impact absorbing surfaces, so the cost and rigidity Considering that the shock absorbing surface is generally 3
