Description

차량용 범퍼 빔 {BUMPER BEAM FOR VEHICLE}Bumper Beam for Cars {BUMPER BEAM FOR VEHICLE}

본 발명은 차량용 범퍼 빔에 관한 것이며, 상세하게는 범퍼 빔의 충돌에너지 다단흡수구조에 관한 것이다.The present invention relates to a bumper beam for a vehicle, and more particularly, to a collision energy multi-stage absorption structure of a bumper beam.

주지하는 바와 같이, 차량의 전후방향 충돌사고시에 그 충돌에너지로부터 차체 및 탑승자를 보호하기 위하여 사이드 멤버등의 프레임에 범퍼를 설치하고 있다.As is well known, bumpers are provided on the frame of side members and the like in order to protect the vehicle body and the occupant from the collision energy in the front and rear collision accident of the vehicle.

종래의 전형적인 범퍼는 도 1에서 참조되고 도 3에 도시한 바와 같이, 차체의 전후방향을 따라 설치되는 사이드 멤버등의 프레임(10a)(10b)에 스테이(11a) (11b)에 의하여 폐단면의 빔 본체(12)를 차체의 폭방향으로 결합하고, 상기 빔 본체(12)의 전길이에 ㄷ형 단면의 보강부재(13)를 그 폐쇄부가 빔 본체(12)의 외측면(충돌에너지 진입방향)에 근접되게 내장설치한 것이다.Conventional typical bumpers are referred to in FIG. 1 and as shown in FIG. 3, by means of stays 11a and 11b in frames 10a and 10b, such as side members, installed along the front and rear directions of the vehicle body. Coupling the beam body 12 in the width direction of the vehicle body, the reinforcing member 13 of the c-shaped cross-section in the full length of the beam body 12, the closed portion of the outer surface of the beam body 12 (collision energy entry direction) It is installed close to the.

상기한 보강부재(13)를 내장한 범퍼 빔은 전길이가 동일강성을 유지함으로 충돌에너지가 작을 때에는 원상으로 복원되고, 충돌에너지가 큰 고속충돌시에는 소정치 이상의 압축응력을 받기 때문에 그 충돌에너지가 비교적 큰 강성으로 제작된 프레임(10a)(10b)에 전달되고, 프레임(10a)(10b)이 변형되면서 충돌에너지를 흡수하는 것이다.The bumper beam containing the reinforcing member 13 maintains the same stiffness of the bumper beam and is restored to the original shape when the collision energy is small, and the impact energy is higher than a predetermined value when the collision energy is high. Is transmitted to the frames 10a and 10b manufactured with a relatively large rigidity, and the frames 10a and 10b are deformed to absorb collision energy.

그러나 상기한 범퍼 빔은 차체의 보호는 양호하지만 고속충돌시에 그 충돌에너지가 프레임(10a)(10b)에 전달되는 것이기 때문에 탑승자의 보호측면에서는 바람직하지 못한 것이다.However, the bumper beam is good in protecting the vehicle body, but the collision energy is transmitted to the frames 10a and 10b during a high-speed collision, which is not preferable in terms of the passenger's protection.

한편 차체 및 탑승자 보호를 동시에 양호하게 하기 위한 범퍼 빔이 미국특허 제 6688661 호 공보에 개시되어 있는바, 상기 범퍼 빔은 도 4와 같이 도 3과 같은 빔 본체(12)의 내부 전길이에 단면 ㄷ형의 보강부재(13)를 내장설치함과 동시에 상기 보강부재(13)의 빔 본체(12)의 스테이(11a)(11b) 결합위치에 외측면(폐쇄부)을 내측보다 그 단면적을 작게 형성하여 강성을 약하게한 요부(14)를 형성하여서, 충돌에너지가 작을 때에는 상기 요부(14)에서 충돌에너지를 흡수한 후 나머지 충돌에너지를 차체에 전달함으로써 빔 본체(12)의 손상을 방지하고, 한편 충돌에너지가 클 때에는 상기 요부(14)에서 충돌에너지를 흡수한 후 나머지 충돌에너지를 차체에 전달되도록 함으로써 차체의 변형을 최소화한 것이다.Meanwhile, a bumper beam for simultaneously improving body and occupant protection is disclosed in U.S. Patent No. 6688661. The bumper beam has a cross-sectional cross-section at an internal length of the beam body 12 as shown in FIG. In addition to the built-in reinforcing member 13 of the reinforcing member 13, the outer surface (closed portion) is formed at the engaging position of the stay (11a) (11b) of the beam body 12 of the reinforcing member 13 to form a smaller cross-sectional area than the inside By forming a recess 14 having weakened rigidity, when the collision energy is small, the collision energy is absorbed by the recess 14 and the remaining collision energy is transmitted to the vehicle body to prevent damage to the beam body 12, while collision When the energy is large, deformation of the vehicle body is minimized by absorbing the collision energy in the recess 14 and transmitting the remaining collision energy to the vehicle body.

그러나 상기한 범퍼 빔은 요부(14)를 보강부재(13)의 스테이(11a)(11b) 결합위치에만 형성하였기 때문에 충돌에너지 흡수가 미약하고, 또한 빔 본체(12)의 요부(14) 설치위치 이외의 부분에 충돌에너지가 가하여지면 충돌에너지가 가하여진 부위의 보강부재(13)가 변형되면서 요부(14)에 전달되기 때문에 범퍼 빔과 차체의 손상방지가 취약하게 되는 문제점이 발생하는 것이다. However, since the bumper beam is formed only at the staying positions of the stays 11a and 11b of the reinforcing member 13, the bumper beam is weak in absorbing collision energy, and the installation position of the recessed portion 14 of the beam body 12 is weak. When the collision energy is applied to the other portion, the reinforcing member 13 of the portion to which the collision energy is applied is deformed and transmitted to the recess 14, thereby preventing the damage of the bumper beam and the vehicle body to be weak.

본 발명은 상기한 문제점을 시정하여, 전길이에서 다단으로 충돌에너지를 흡수하도록하여 차체 및 탑승자의 보호를 양호하게 할 수 있는 차량용 범퍼 빔을 제공하는 것을 목적으로 한다.The object of the present invention is to provide a bumper beam for a vehicle that can improve the protection of the vehicle body and the occupant by absorbing collision energy in multiple stages at all lengths.

상기한 목적을 달성하기 위하여, 본 발명은 프레임에 스테이로 결합하는 폐단면의 빔 본체와, 상기 빔 본체의 전길이에 그 폐쇄부가 빔 본체의 외측면에 근접되게 내장설치한 보강부재를 구비하고, 상기 보강부재는 그 전길이에 외측면으로 갈수록 단면적이 감소되는 다수단의 계단형 돌기를 형성하여서 된 것을 특징으로 한다.In order to achieve the above object, the present invention includes a beam main body of the closed end coupled to the frame stays, and a reinforcing member in which the closing portion at the full length of the beam main body is installed close to the outer surface of the beam main body; , The reinforcing member is characterized in that the front length is formed by forming a plurality of steps of stepped projection is reduced in cross-section toward the outer surface.

본 발명은 도 1에서 참조되고 도 2에 도시한 바와 같이, 사이드 멤버등의 프레임(10a)(10b)에 스테이(11a)(11b)에 의하여 폐단면의 빔 본체(12)를 차체의 폭방향으로 결합하고, 상기 빔 본체(12)에는 그 전길이에 보강부재(20)를 그 폐쇄부가 빔 본체(12)의 외측면(충돌에너지 진입방향)에 근접되게 내장설치하며, 상기 보강부재(20)는 그 전길이에 외측면으로 갈수록 그 단면적이 감소되는 다수단의 계단형 돌기(120a)(120b)(120c)를 형성한 것이다.As shown in FIG. 1 and shown in FIG. 2, this invention makes the beam main body 12 of the closed end surface the width direction of a vehicle body by the stay 11a, 11b in frame 10a, 10b, such as a side member. And the reinforcing member 20 is installed in the beam main body 12 at its full length so that its closed portion is close to the outer surface (the collision energy entry direction) of the beam main body 12, and the reinforcing member 20 is installed. ) Is formed in a plurality of stepped projections (120a, 120b, 120c) whose cross-sectional area decreases toward the outer side at its entire length.

상기 계단형 돌기(120a)(120b)(120c)는 상하대칭으로 형성하여 충돌에너지를 흡수할 때 특히 정면충돌시 충돌에너지를 균등하게 흡수되도록하고, 또한 일체로 형성하여 제조원가를 절감토록한 것이다.The stepped protrusions 120a, 120b, and 120c are formed in up-and-down symmetry to absorb the collision energy evenly when absorbing the collision energy, and are also formed integrally to reduce manufacturing costs.

또한 상기 계단형 돌기(120a)(120b)(120c)는 그 연결부를 수직부(121a) (121b)(121c)로 연결하여 충돌에너지를 흡수할 때 충돌에너지가 직각으로 전달되면서 계단형 돌기(120a)(120b)(120c)보다 먼저 변형하도록 함으로써 충돌에너지 흡수를 더욱더 양호하게한 것이다.In addition, the stepped protrusions 120a, 120b, and 120c connect the connecting portions to the vertical portions 121a, 121b, and 121c to absorb the collision energy when the collision energy is transmitted at a right angle. By making it deform before 120b and 120c, the collision energy absorption is much better.

이상과 같은 본 발명은 차량의 충돌시 그 충돌에너지가 빔 본체(12)의 외측면의 어느 위치에 가하여지더라도 충돌에너지가 가하여지는 부분에서 계단형 돌기(120a)(120b)(120c)의 외측면으로부터 즉 단면적이 제일 작은 외측면 돌기(120c)부터 단면적이 증가하는 돌기(120b)와 돌기(120a) 순으로 변형하면서 충돌에너지를 흡수하고, 보강부재(20)에서 흡수하고 남은 충돌에너지는 스테이(11a)(11b)를 경유하여 차체에 전달되어 흡수되는 것이다.According to the present invention as described above, even when the collision energy is applied to any position of the outer surface of the beam main body 12 during the collision of the vehicle, in addition to the stepped protrusions 120a, 120b, 120c at the portion where the collision energy is applied. The impact energy is absorbed while deforming from the side surface, that is, the outer surface protrusion 120c having the smallest cross-sectional area from the protrusion 120b and the protrusion 120a having the increased cross-sectional area, and the remaining collision energy absorbed by the reinforcing member 20 is stayed. It is transmitted to and absorbed by the vehicle body via (11a) (11b).

상기와 같이 보강부재(20)의 전길이에 걸쳐 외측면으로 갈수록 그 단면적이 감소되는 계단형 돌기(120a)(120b)(120c)를 형성함으로써 충돌에너지가 빔 본체(12)의 어느위치에 가하여지더라도 충돌에너지가 가하여지는 부분에서 직접 충돌에너지를 흡수하고, 또한 충돌에너지는 다단으로 흡수함으로써 충돌에너지를 양호하게 흡수할 수 있기 때문에 차체 및 탑승자의 보호를 양호하게 할 수 있는 것이다.As described above, by forming stepped protrusions 120a, 120b, and 120c whose cross-sectional area decreases toward the outer surface over the entire length of the reinforcing member 20, collision energy is applied to any position of the beam body 12. Even though the collision energy is absorbed directly, the collision energy is absorbed directly, and the collision energy is absorbed in multiple stages so that the collision energy can be absorbed well. Thus, the protection of the vehicle body and the occupant can be improved.

이상과 같이 본 발명은 빔 본체에 내장설치한 보강부재의 전길이에 외측면으로 갈수록 단면적이 감소되는 계단형 돌기를 형성하였음으로 보강부재의 어느 위치에서도 충돌에너지를 양호하게 흡수할 수 있기 때문에 차체 및 탑승자의 보호가 양호하여 즉 차체의 손상을 최소화함과 동시에 탑승자의 상해치를 감소할 수 있는 것이다.As described above, the present invention forms a stepped protrusion having a cross-sectional area that decreases toward the outer side at the entire length of the reinforcing member installed in the beam body, so that collision energy can be absorbed well in any position of the reinforcing member. And the protection of the occupant is good, that is to minimize the damage of the vehicle body and at the same time can reduce the injury value of the occupant.

또한 빔 본체의 단면적을 감소하면서 충돌에너지 흡수를 양호하게 할 수 있음으로 범퍼의 돌출길이가 작아지는 추세에 부응하고, 외관설계의 자유도를 제고할 수 있는 것이다.In addition, it is possible to improve the collision energy absorption while reducing the cross-sectional area of the beam main body to meet the trend of shortening the bump length of the bumper, it is possible to improve the freedom of appearance design.
