Description

차량용 범퍼빔{BUMPER BEAM FOR VEHICLES}BUMPER BEAM FOR VEHICLES [0001]

본 발명은 차량용 범퍼빔에 관한 것으로서, 보다 상세하게는 범퍼빔의 단면 구조를 개선하여 충돌성능을 향상시키고, 강성을 확보할 수 있도록 하는 차량용 범퍼빔에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a bumper beam for a vehicle, and more particularly, to a bumper beam for a vehicle that improves the cross-sectional structure of the bumper beam to improve collision performance and ensure rigidity.

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.Generally, a bumper in a vehicle is a shock absorber installed at the front and rear of a vehicle so that when a vehicle collides with another vehicle or a fixed body, the shock is absorbed to secure passengers' safety while minimizing the deformation of the vehicle body .

이러한 범퍼는 차량의 전,후방에 차폭 방향으로 배치되는 범퍼빔이 크래쉬 박스를 통하여 차체측 사이드 멤버에 장착되고, 범퍼빔의 전방에는 충격력을 흡수하는 에너지 업소버가 배치되며, 범퍼커버가 상기 범퍼빔과 에너지 업소버를 감싸면서 설치된다. In this bumper, a bumper beam arranged in the vehicle width direction on the front and rear sides of the vehicle is mounted to the side member on the vehicle body side through the crash box, an energy absorber for absorbing the impact force is disposed in front of the bumper beam, And the energy absorber.

도 1은 종래 기술에 따른 차량용 범퍼빔의 사시도이다.1 is a perspective view of a vehicle bumper beam according to the prior art.

도 1을 참조하면, 상기 범퍼빔(101; 프론트 범퍼의 경우)은 후방 양측에 크래쉬 박스(103; 또는 스태이)가 체결된 상태로, 차체 측의 사이드 멤버에 조립된다. Referring to FIG. 1, the bumper beam 101 (in the case of a front bumper) is assembled to a side member on the vehicle body side in a state where a crash box 103 (or stays) is fastened to both sides of the rear side.

상기 범퍼빔(101)은 상부 중앙에 충돌성능의 확보 및 강성 보강과 충돌 시의 언더 라이딩 현상 등을 방지하기 위한 보강부재(105)가 설치된다. The bumper beam 101 is provided with a reinforcing member 105 at the center of its upper portion for preventing collision and for preventing under-riding phenomenon during stiffness reinforcement and collision.

그러나 종래의 범퍼빔(101)은 충돌성능조건을 만족하기 위해 보강부재(105)를 적용함에 따라 단품추가로 용접공정이 추가되고, 중량 측면에서도 불리한 단점이 있다. However, according to the conventional bumper beam 101, since the reinforcing member 105 is applied to satisfy the impact performance condition, a welding process is further added to the bumper beam 101, which is disadvantageous in terms of weight.

이와 같이, 종래의 범퍼빔(101)은 유리한 충돌성능을 확보하기 위하여 주로 범퍼빔(101)의 내외부에 별도의 보강재를 추가하는 것으로, 중량, 공정, 원가 측면에서 불리한 단점이 있다.As described above, the conventional bumper beam 101 has a disadvantage in terms of weight, process, and cost in that a separate reinforcing material is added to the inside and the outside of the bumper beam 101 in order to secure favorable collision performance.

또한, 종래의 범퍼빔(101)은 단면 구조상, 차량의 전면 충돌 시, 도 2에서 도시한 바와 같이, 센터부(C)에 과도한 충격에너지가 집중되어 센터부(C)의 변형이 과도하게 발생되는 단점이 있다. 2, excessive impact energy is concentrated on the center portion C and the deformation of the center portion C is excessively generated due to the excessive impact energy being concentrated on the center portion C when the front surface of the conventional bumper beam 101 collides with the front of the vehicle .

본 발명의 실시 예는 2개의 폐단면으로 이루어지는 범퍼빔의 전면과 후면에 충격에너지의 분산과 곡률 성형 시에 곡률반경 내주면에 덴트의 발생을 방지할 수 있도록 요홈으로 이루어지는 포밍홈을 추가하여 충돌성능을 확보하고 품질문제를 해소할 수 있는 차량용 범퍼빔을 제공하고자 한다. The embodiment of the present invention is characterized in that impact energy is dispersed on the front and rear surfaces of the bumper beam composed of two closed end faces and a foaming groove made of a groove is added to prevent the generation of dent on the inner radius of curvature radius during curvature molding, And to provide a bumper beam for a vehicle which can solve the quality problem.

본 발명의 하나 또는 다수의 실시 예에서는 패널소재를 롤 포밍하여 일정한 형상으로 성형되는 차량용 범퍼빔에 있어서, 전면이 수직면으로 형성되고, 후면에는 수직면에 요홈으로 이루어진 포밍홈이 형성되는 상부 폐단면; 전면과 후면의 각 수직면에 요홈으로 이루어지는 포밍홈이 형성되는 하부 폐단면; 및 상기 상부 폐단면과 하부 폐단면을 연결하는 연결부를 포함하는 차량용 범퍼빔을 제공할 수 있다.According to one or more embodiments of the present invention, there is provided a bumper beam for a vehicle which is formed into a predetermined shape by roll-forming a panel material, wherein the front surface is formed as a vertical surface and the rear surface is formed with a foaming groove formed as a groove on a vertical surface; A lower closed end surface in which forming grooves formed by recesses are formed on respective vertical surfaces of the front surface and the rear surface; And a connecting portion connecting the upper closed end face and the lower closed end face.

또한, 상기 패널소재의 양 단부는 상기 상부 폐단면과 하부 폐단면 각각으로부터 수직 절곡되어 상기 연결부의 후면에 용접될 수 있다.Both end portions of the panel material may be vertically bent from the upper closed end and the lower closed end to be welded to the rear surface of the connecting portion.

또한, 상기 연결부는 상기 상부 및 하부 폐단면의 전면에 대하여 일정깊이로 절곡된 골부와, 상기 상부 및 하부 폐단면의 전면과 동일면으로 형성되는 산부로 이루어질 수 있다. The connection portion may include a valley portion bent to a predetermined depth with respect to the front surface of the upper and lower closed end surfaces, and a hill portion formed to be flush with the front surface of the upper and lower closed end surfaces.

또한, 상기 포밍홈은 곡면으로 형성될 수 있다.Further, the forming grooves may be formed as curved surfaces.

본 발명의 실시 예는 2개의 폐단면으로 이루어지는 범퍼빔의 전면과 후면에 각각 요홈으로 이루어지는 포밍홈을 추가하여 충격에너지의 분산과 곡률 성형 시에 곡률반경 내주면에 덴트의 발생을 방지할 수 있다. The embodiment of the present invention can prevent the generation of dents on the inner circumferential surface of the radius of curvature at the time of curvature shaping and impact energy dispersion by adding a forming groove formed as a groove on the front and back surfaces of the bumper beam composed of two closed end faces.

이로 인해 충돌성능을 확보하고, 우수한 품질의 범퍼빔을 제공할 수 있다. As a result, the collision performance can be ensured and a bumper beam of excellent quality can be provided.

또한, 별도의 보강부재를 적용하지 않아도 됨에 따라 공정이 줄어들며, 중량 측면에서도 이점이 있다. 즉, 중량, 공정, 원가의 추가 없이도, 단면상에 포밍홈으로 강성을 보강하여 충돌성능에 대응할 수 있다.In addition, since a separate reinforcing member is not required, the process is reduced, and there is an advantage in terms of weight. That is, without adding weight, process, and cost, the stiffness can be reinforced by the forming grooves on the cross section to cope with the impact performance.

도 2와 도 3을 참조하면, 본 발명의 실시 예에 따른 차량용 범퍼빔(1)은 패널소재를 롤 포밍하여 2개의 폐단면(F1,F2)을 갖는 롤 포밍 관재를 일정 곡률로 성형하여 형성된다. 2 and 3, a bumper beam 1 for a vehicle according to an embodiment of the present invention is formed by roll-forming a panel material to form a roll-forming pipe material having two closed end faces F1 and F2 at a predetermined curvature, do.

상기 범퍼빔(1)의 후면 양측에는 각각 크래쉬 박스(3)가 설치되고, 양측 크래쉬 박스(3)를 통하여 프론트 사이드 멤버(미도시)에 조립된다. A crash box 3 is installed on both sides of the rear side of the bumper beam 1 and is assembled to a front side member (not shown) through the both side crash boxes 3.

상기 범퍼빔(1)은 패널소재를 롤 포밍하여 상부 폐단면(F1)과 하부 폐단면(F2)을 갖는 일정한 형상으로 성형된다. The bumper beam 1 is formed into a predetermined shape having an upper closed end face F1 and a lower closed end face F2 by roll-forming the panel material.

상기 상부 폐단면(F1)은 대략 사각의 형상으로 형성되며, 전면(11)이 수직면으로 형성되고, 후면(13)에는 수직면에 요홈으로 이루어진 포밍홈(G1)이 형성된다. The upper closed end face F1 is formed in a substantially rectangular shape and the front face 11 is formed as a vertical face and the rear face 13 is formed with a forming groove G1 formed as a groove on a vertical face.

상기 하부 폐단면(F2)은 상기 상부 폐단면(F1)과 폭(W)이 같은 대략 사각의 형상으로 형성되며, 전면(21)과 후면(23)에 각각 수직면에 요홈으로 이루어지는 포밍홈(G2,G3)이 형성된다. The lower closed end face F2 is formed in a substantially rectangular shape having the same width W as the upper closed end face F1 and has a forming groove G2 , G3) are formed.

여기서, 상기 포밍홈(G1,G2,G3)은 곡면으로 형성되는데, 상기 포밍홈(G1,G2,G3)은 각각의 위치에 따라 곡면의 곡률(R1,R2,R3)이 다르게 형성된다. Here, the forming grooves G1, G2 and G3 are curved surfaces. The curvatures R1, R2 and R3 of the curved surfaces are formed differently depending on the positions of the forming grooves G1, G2 and G3.

이러한 상부 폐단면(F1)과 하부 폐단면(F2)은 상호 연결부(J)를 통하여 연결된다. The upper closed end face F1 and the lower closed end face F2 are connected to each other through the interconnection J.

즉, 상기 연결부(J)는 상기 상부 및 하부 폐단면(F1,F2)의 각 전면(11,12)에 대하여 일정깊이로 절곡된 골부(31)와, 상기 상부 및 하부 폐단면(F1,F2)의 각 전면(11,12)과 일치하도록 동일면으로 형성되는 산부(33)로 이루어진다. That is, the connecting portion J includes a valley portion 31 bent to a predetermined depth with respect to the front surfaces 11 and 12 of the upper and lower closed surfaces F1 and F2 and the upper and lower closed surfaces F1 and F2 And a crest portion 33 formed in the same plane so as to coincide with the front surfaces 11,

또한, 상기 연결부(J)에는 상기 패널소재의 양 단부(41,43)가 용접되어 고정되는데, 상기 패널소재의 일 단부(41)는 상기 상부 폐단면(F1)으로부터 수직 절곡되어 상기 골부(31)의 후면에 용접되고, 상기 패널소재의 타 단부(43)는 상기 하부 폐단면(F2)으로부터 수직 절곡되어 상기 산부(33)의 후면에 용접된다. The end portion 41 of the panel material is vertically bent from the upper closed end face F1 so as to be connected to the valley portion 31 And the other end 43 of the panel blank is vertically bent from the lower closed end face F2 and welded to the rear face of the hill 33. [

이때, 상기 패널소재의 양 단부(41,43)는 스폿 용접(W)에 의해 용접되거나, 레이저 용접 또는 CO2 아크 용접 등에 의해 접합하여 고정할 수 있다. At this time, both end portions 41 and 43 of the panel material can be welded by spot welding (W), or can be jointed and fixed by laser welding or CO2 arc welding or the like.
