본 발명의 자동차용 범퍼는 도 2와 도 3에 도시하고 있는 바와 같이,As the bumper for automobiles of the present invention is shown in Figs. 2 and 3,
차체의 사이드멤버에는 범퍼빔(130)이 범퍼스테이를 매개로 하요 고정되어 있고, 상기 범퍼빔(130)의 전면에는 상하부에 각각의 변형부(141)가 전면으로 소정각도 경사지게 형성된 보강구조물(140)이 고정 설치되어 있으며, 상기 보강구조물(140)의 전면에는 에너지업소버(120)가 설치되어 있다.The bumper beam 130 is fixed to the side member of the vehicle body via the bumper stay, and the front and rear surfaces of the bumper beam 130 have respective deformable portions 141 inclined at a predetermined angle to the front and lower portions 140. ) Is fixedly installed, the energy absorber 120 is installed on the front of the reinforcing structure 140.
한편, 상기 에너지업소버(120)의 전방에는 외장재로서의 범퍼커버(110)가 설치되어 있다.On the other hand, the front of the energy absorber 120 is provided with a bumper cover 110 as an exterior material.
이와 같이 구성되는 본 발명의 자동차용 범퍼는 사이드멤버(미도시)에 범퍼빔(130)을 고정하고, 상기 범퍼빔(130)의 전면에 변형부(141)가 상하부에 각각 형성되어 있는 보강구조물(140)을 고정하며, 상기 보강구조물(140)의 전면에는 에너지업소버(120)를 고정한 후, 에너지업소버(120)의 전방으로 범퍼커버(110)를 설치하는 것에 의해 차체에 설치된다.The bumper for automobiles of the present invention configured as described above fixes the bumper beam 130 to a side member (not shown), and the reinforcing structure in which the deformation parts 141 are formed on the front and bottom of the bumper beam 130, respectively. The fixing unit 140 is fixed to the front side of the reinforcing structure 140, and then fixed to the energy absorber 120, and is installed in the vehicle body by installing the bumper cover 110 in front of the energy absorber 120.
이에 따라, 차량을 운행하는 보행자와 충돌 및 추돌 사고가 발생하여 범퍼커버(110)에 충격하중이 가해지면, 1차적으로 범퍼커버(110)를 통해 전달되는 충격에너지에 의해 에너지업소버(120)가 변형되면서 충격에너지를 흡수하며 보행자의 신체가 부상당하는 것을 억제하고, 상기 에너지업소버(120)가 충격을 흡수하고 남은 충격에너지는 보강구조물(140)의 상하부에 형성된 변형부(141)가 범퍼커버(110)의 내측면과 접하면서 차량의 후부로 변형되도록 펼쳐지면서 충격에너지가 흡수된다.Accordingly, when an impact load is applied to the bumper cover 110 due to a collision and a collision accident with a pedestrian running the vehicle, the energy absorber 120 is primarily driven by the impact energy transmitted through the bumper cover 110. Absorbs the impact energy while suppressing the injury of the pedestrian body, the energy absorber 120 absorbs the impact and the remaining impact energy is the deformable portion 141 formed on the upper and lower portions of the reinforcing structure 140 bumper cover ( Shock energy is absorbed while being deployed to be deformed to the rear of the vehicle while being in contact with the inner surface of the 110.
이때, 상기 범퍼커버(110)는 상하부가 변형부(141)에 의해 안내되면서 상하로 동시에 펼쳐지면서 보행자의 다리부와의 접촉면적이 증대되는 것에 의해 상기 보행자 다리부의 무릎 골절부위가 꺾이지 않게 된다.In this case, the bumper cover 110 is guided by the deformable portion 141 and is simultaneously extended up and down, thereby increasing the contact area with the leg portion of the pedestrian so that the knee fracture portion of the pedestrian leg portion is not bent.
또한, 상기 변형부(141)가 상하부에 각각 형성된 보강구조물(140)은 도 3에 도시하고 있는 바와 같이, 세로방향으로 소정의 간격을 두고 복수개 형성된 연결대(142)로 연결되어 있어, 상기 보강구조물을 차체의 전방에 설치하는 경우에도 차체의 중량이 과도하게 증가하지 않게 됨을 밝혀 둔다.In addition, the reinforcing structure 140 formed at the upper and lower portions of the deformable portion 141 is connected to a plurality of connecting rods 142 formed at a predetermined interval in the vertical direction, as shown in FIG. It is noted that even when the front of the vehicle body is installed, the weight of the vehicle body does not increase excessively.
따라서 이러한 본 발명은 차량을 운행중 충돌 및 추돌 사고가 발생하여 보행자의 다리부가 범퍼커버(110)에 접촉하는 경우에도, 상기가 보강구조물(140)의 변형부(141)에 의해 안내되면서 보행자 다리부와의 접촉면적이 확장되도록 상하로 펼쳐지는 것에 의해, 상기 보행자의 다리부의 무릎 골절부위에 꺾임 현상이 발생하지 않게 됨은 물론, 범퍼(100)의 돌출량이 최소화되어 차량의 상품성이 향상되도록 하는 효과가 있는 매우 유용한 발명이다.Therefore, in the present invention, even when a collision and a collision accident occurs while driving a vehicle, the pedestrian leg part is guided by the deformation part 141 of the reinforcing structure 140 even when the leg part of the pedestrian contacts the bumper cover 110. By spreading up and down to expand the contact area of the pedestrian, the bending phenomenon does not occur at the knee fracture portion of the leg part of the pedestrian, and the protrusion amount of the bumper 100 is minimized to improve the product quality of the vehicle. That is a very useful invention.
