Description
본 고안은 자동차의 범퍼빔에 관한 것으로, 특히 범퍼스테이를 매개로 차체에 연결되는 범퍼빔의 타워부의 4각모서리가 상하 및 좌우 측벽부에 비해 상대적으로 얇게 형성되어 충돌이 가해질 때에 쉽게 좌굴이 발생되도록 해서 범퍼빔의 충격흡수능력을 향상시키고 충격전달의 절연효과도 향상시킬 수 있도록 된 자동차의 범퍼빔구조에 관한 것이다.The present invention relates to a bumper beam of an automobile, and in particular, a quadrilateral corner of a tower portion of a bumper beam connected to a vehicle body via a bumper stay is relatively thinner than upper, left, and left and right sidewall portions so that buckling occurs easily when a collision is applied. The present invention relates to a bumper beam structure of a vehicle that is capable of improving the shock absorbing ability of the bumper beam and improving the insulation effect of the shock transfer.
일반적으로 자동차에는 주행중에 충돌이나 추돌사고시에 탑승자 등을 보다 안전하게 보호하기 위해 차체의 전방 및 후방에 범퍼가 장착되어 있는 바, 이 범퍼는 외면을 이루는 범퍼카바와, 충격이 가해질 때에 충격을 적절히 흡수하면서 충격 저항기능을 하는 범퍼빔, 이 범퍼빔을 차체에 체결시키는 범퍼스테이 등으로 구성되어 있다.Generally, bumpers are mounted on the front and rear of the vehicle body to protect the passengers in the event of a collision or collision while driving, and the bumper covers the bumper cover forming the outer surface and absorbs the shocks when the impact is applied. A bumper beam having a shock resistance function, and a bumper stay for fastening the bumper beam to the vehicle body.
여기서 상기 범퍼빔은 충격저항강성을 높이기 위해 스틸재질로 만들어지는 경우에는 충격흡수능력을 향상시키기 위해 별도의 에너지 업소버가 결합되게 되어 있는 바, 이 스틸재질의 범퍼빔은 제작이 어렵고 구조가 복잡할 뿐만 아니라 제작 단가도 비싸기 때문에 충격흡수능력과 충격저항강성이 우수한 플라스틱 범퍼빔을 사용하는 자동차도 있다.Where the bumper beam is made of a steel material to increase the impact resistance stiffness, a separate energy absorber is to be combined to improve the shock absorbing ability, this bumper beam of steel material is difficult to manufacture and the structure is complicated In addition, some automobiles use plastic bumper beams with excellent shock absorption and impact resistance stiffness due to their high manufacturing cost.
도 1은 상기한 종래의 플라스틱 재질로 사출성형된 범퍼빔을 도시한 것인 바, 즉 이 범퍼빔은 차체의 폭방향을 따라 길게 연장되면서 만곡되게 형성됨과 더불어 단면이 ㄷ자채널형상으로 형성된 빔부(101)와, 이 빔부의 채널속에 일체로 형성되면서 빔부의 강성를 보완하기 위해 격자무늬형상으로 형성된 다수개의 리브(102) 및, 상기 빔부를 스테이를 매개로 차체에 체결하기 위해 빔부의 좌우 양측에 각각 폐단면으로 2개씩 형성된 타워부(103)를 갖춘 구조로 되어 있다.1 is a view illustrating a bumper beam injection-molded with the conventional plastic material, that is, the bumper beam is formed to be curved while extending along the width direction of the vehicle body, and a beam portion having a cross-section having a c-channel shape ( 101, a plurality of ribs 102 formed in a lattice pattern to complement the rigidity of the beam part while being integrally formed in the channel of the beam part, and on the left and right sides of the beam part for fastening the beam part to the vehicle body via the stay, respectively. It has a structure with the tower part 103 formed in two by the closed cross section.
여기서 상기 타워부(103)는 도 1 및 도 2에 도시된 바와 같이 4각기둥형상을 하고서 그 단면이 4각형상으로 형성되어 있고, 또 4각형을 이루는 타워부의 상하 측벽과 좌우 측벽은 각각 동일한 두께로 형성되어 있다.Here, the tower portion 103 has a quadrangular column shape as shown in FIGS. 1 and 2, the cross section of which is formed in a quadrangular shape, and the upper and lower side walls and the left and right side walls of the tower portion constituting the quadrangles have the same thickness, respectively. It is formed.
이에 따라 자동차의 충돌이나 추돌사고시에 그 충격이 범퍼빔에 전달되면, 이 범퍼빔은 적절히 변형되면서 충격을 흡수하여 완화시켜줌과 더불어 차체가 승객쪽으로 밀려지지 않도록 충격에 저항되게 된다.Accordingly, when the impact is transmitted to the bumper beam during the collision or collision of the vehicle, the bumper beam is deformed while absorbing and mitigating the shock, and the vehicle body is resistant to the impact so that the vehicle body is not pushed toward the passenger.
그런데 상기한 종래의 범퍼빔구조에서는 범퍼빔에 충격이 가해질 때에 상기 타워부가 동일한 두께로 이루어진 4각형상을 하고 있기 때문에 적절한 변형을 발생시키지 못하고, 이 때문에 범퍼빔을 통해 타워부가 전달된 충격은 타워부에 적절히 흡수되지 않고 그대로 차체로 전달되게 되어, 충격흡수능력이 미흡하다고 하는 결점이 있었다.However, in the conventional bumper beam structure, when the shock is applied to the bumper beam, the tower part has a quadrangular shape having the same thickness, so that it does not generate an appropriate deformation, and therefore, the shock transmitted by the tower part through the bumper beam is a tower. There was a drawback that it was not properly absorbed by the part and was delivered to the vehicle body as it was, so that the shock absorbing ability was insufficient.
이에 본 고안은 상기한 결점을 해소하기 위해 안출된 것으로, 범퍼빔에 충격이 가해질 때에 범퍼빔의 타워부가 쉽게 좌굴로 변형되면서 충격을 적절히 흡수하도록 하여 충격흡수능력을 향상시킬 수 있도록 된 자동차의 범퍼빔구조를 제공함에 그 목적이 있다.Therefore, the present invention was devised to solve the above-mentioned drawbacks, and the bumper beam of the car is designed so that the tower part of the bumper beam is easily deformed into a buckling when the impact is applied to the bumper beam so that the shock absorbing ability can be properly absorbed to improve the shock absorbing ability. The purpose is to provide a beam structure.

상기한 바의 목적을 달성하기 위한 본 고안은, 차체의 폭방향을 따라 길게 연장되면서 만곡되게 형성됨에 더불어 단면이 ㄷ자 채널형상으로 형성된 빔부와, 이 빔부의 채널속에 일체로 형성되면서 빔부의 강성을 보완하기 위해 격자무늬형상으로 형성된 다수개의 리브 및 , 상기 빔부를 스테이를 매개로 차체에 체결하기 위해 빔부의 좌우 양측에 각각 4각기둥형상으로 형성된 타워부를 갖춘 자동차의 범퍼빔에 있어서, 상기 타워부의 각 4각모서리가 상하 및 좌우측벽에 비해 두께가 상대적으로 얇게 형성된 것을 특징으로 한다.The present invention for achieving the above object, the beam portion is formed in a curved shape extending in the longitudinal direction of the vehicle body, the cross section is formed in the U-shaped channel portion, and the beam portion is formed integrally in the channel of the beam portion while the rigidity of the beam portion In the bumper beam of an automobile having a plurality of ribs formed in a grid pattern to complement and the tower portion formed on each of the left and right sides of the beam portion to fasten the beam portion to the vehicle body via the stay, each of the tower portion The four corners are characterized in that the thickness is formed relatively thinner than the upper and lower and left and right walls.
이하 본 고안의 실시예를 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 3은 본 고안에 따른 사출 범퍼빔의 사시도, 도 4는 도 3의 A-A선 단면도인 바, 즉 차체의 폭방향을 따라 길게 연장되면서 만곡되게 형성됨에 더불어 단면이 ㄷ자 채널형상으로 형성된 빔부(1)와, 이 빔부의 채널속에 일체로 형성되면서 빔부의 강성을 보완하기 위해 격자무늬형상으로 형성된 다수개의 리브(2) 및 , 상기 빔부를 스테이를 매개로 차체에 체결하기 위해 빔부의 좌우 양측에 각각 폐단면으로 2개씩 형성된 타워부(3)를 갖춘 구조로 되어 있다.3 is a perspective view of an injection bumper beam according to the present invention, FIG. 4 is a cross-sectional view taken along line AA of FIG. 3, that is, the beam part 1 is formed to be curved while extending along the width direction of the vehicle body and has a cross-section in the shape of a c channel. ) And a plurality of ribs 2 formed in a lattice pattern to complement the rigidity of the beam part while being integrally formed in the channel of the beam part, and on the left and right sides of the beam part for fastening the beam part to the vehicle body via the stay, respectively. It has a structure with the tower part 3 formed in two by the closed cross section.
여기서 상기 타워부(3)는 도 3 및 도 4에 도시된 바와 같이 4각기둥형상을 하고서 그 단면이 4각형성으로 형성되어 있고, 또 4각형을 이루는 타워부의 상·하측벽(3a,3b)과 좌·우측벽(3c,3d)은 각각 동일한 두께로 형성되어 있다.Here, the tower portion 3 has a quadrangular column shape as shown in FIGS. 3 and 4, the cross section of which is formed in a quadrangular shape, and the upper and lower walls 3a and 3b of the tower portion forming a quadrangular shape. The left and right side walls 3c and 3d are formed with the same thickness, respectively.
그리고 상기 타워부의 각 측벽(3a,3b,3c,3d)들과 인접한 4각의 각 모서리(3e)는 각 측벽들에 비해 그 두께가 상대적으로 얇게 형성되어 진다.The four corners 3e adjacent to each of the side walls 3a, 3b, 3c, and 3d of the tower portion are formed to be relatively thinner than the respective side walls.
이에 따라 자동차의 주행중에 충돌이나 추돌사고 인해 범퍼빔에 충격이 가해지면, 상기 빔부가 먼저 충격을 인해 적절히 변형되면서 완화시켜 주게 되고, 이 빔부에서 미처 흡수하지 못한 충격은 상기 타워부로 전달되게 되는 데, 이 타워부는 도 5에 도시된 바와 같이 좌굴로 인해 변형되면서 충격을 2차적으로 흡수하여 완화시켜주게 되므로, 타워부를 통해 차체에 전달되는 충격을 효과적으로 저감시켜 탑승자 등을 보다 안전하게 보호해 줄 수 있을 뿐만 아니라 차체의 손상도 방지해 주게 되는 것이다.Accordingly, when an impact is applied to the bumper beam due to a collision or collision while driving the vehicle, the beam portion is first deformed and moderated due to the impact, and an impact not absorbed by the beam portion is transmitted to the tower portion. As the tower part is deformed due to buckling as shown in FIG. 5, the second part absorbs and mitigates the shock, thereby effectively reducing the shock transmitted to the vehicle body through the tower part and thus more effectively protecting the occupant. It also prevents damage to the bodywork.
이상 설명한 바와 같이 본 고안에 따른 자동차 범퍼빔구조에 의하면, 자동차의 주행중에 충돌이나 추돌사고로 인해 범퍼빔에 충격이 가해지면, 빔부의 적절한 변형으로 1차적으로 충격을 흡수해서 저감시킴과 더불어 상기 타워부의 좌굴로 인한 변형으로 2차적으로 충격을 흡수해 저감시켜 주게 되므로, 차체의 손상을 방지하고 탑승자 등을 보다 안전하게 보호할 수 있는 효과가 있다.As described above, according to the vehicle bumper beam structure according to the present invention, when an impact is applied to a bumper beam due to a collision or collision while driving a vehicle, the impact is primarily absorbed and reduced by appropriate deformation of the beam part. Since the impact due to the buckling of the tower portion is absorbed and reduced secondarily, it is possible to prevent damage to the vehicle body and to protect the occupants more safely.
