Abstract

PURPOSE: A structure of a bumper for a vehicle is provided to protect a vehicle body and pedestrians at the same time by dually installing a high foam absorber and a low foam absorber between a bumper cover and a supporting beam. CONSTITUTION: A bumper cover(20) is installed at the lower end of a panel(10) and a supporting beam(30) is installed in the bumper cover to protect a vehicle body in case of a collision. A high foam absorber(22) is placed between the bumper cover and the supporting beam. At that time, the installation cross section of the supporting beam is minimized to place a low foam absorber(24) between the high foam absorber and the supporting beam. Thus, collision energy is triply absorbed to protect the vehicle body and a pedestrian at the same time.

이하 첨부도면을 참조하여 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 발명은 패널(10) 하단에 범퍼커버(20)가 장착되고 상기 범퍼커버(20) 내부에는 자동차의 충돌시 차체를 보호하기 위한 지지용 빔(30)이 장착되며 상기 범퍼커버(20)와 지지용 빔(30) 사이에 고발포 업소버(22)가 개재된 자동차용 범퍼의 구조에 있어서, 상기 지지용 빔(30)의 장착되는 단면적을 최소화하여, 상기 고발포 업소버(22)와 지지용 빔(30) 사이에 저발포 업소버(24)를 개재한 것을 특징으로 한다.According to the present invention, the bumper cover 20 is mounted at the bottom of the panel 10, and the support beam 30 is mounted inside the bumper cover 20 to protect the vehicle body when the vehicle collides with the bumper cover 20. In the structure of the bumper for automobile having the high foamed absorber 22 interposed between the supporting beams 30, the cross-sectional area of the supporting beam 30 is minimized, and the high foamed absorber 22 is supported. The low foaming absorber 24 is interposed between the beams 30.

특히, 상기 저발포 업소버(24)는 10 배품 이하인 고밀도의 폴리에틸렌 재질인 것을 특징으로 한다.In particular, the low-foam absorber 24 is characterized in that the polyethylene material of high density less than 10 times.

본 발명을 좀 더 상세히 설명하면 다음과 같다.The present invention is described in more detail as follows.

첨부한 도 1은 본 발명에 따른 자동차용 범퍼의 구조를 나타내는 단면도로써, 패널(10) 하단에 장착된 범퍼커버(20) 내부에는 자동차의 충돌시 차체를 보호하기 위한 지지용 빔(30)이 장착되는 바, 상기 범퍼커버(20)와 지지용 빔(30) 사이의 충격 흡수공간을 최대화하기 위하여 상기 지지용 빔(30)의 장착되는 단면적을 최소화하여 형성한다.1 is a cross-sectional view illustrating a structure of a bumper for a vehicle according to the present invention, wherein a support beam 30 for protecting a vehicle body during a collision of a vehicle is provided inside a bumper cover 20 mounted at a bottom of the panel 10. The bar is formed by minimizing the mounting cross-sectional area of the support beam 30 in order to maximize the shock absorbing space between the bumper cover 20 and the support beam 30.

상기 범퍼커버(20)와 지지용 빔(30) 사이에 개재되는 고발포 업소버(22)는 15~30 배품의 저밀도 폴리에틸렌 재질의 업소버로써 보행자 충돌시 보행자의 상해치를 최소화 할 수 있다.The high foamed absorber 22 interposed between the bumper cover 20 and the support beam 30 is a low-density polyethylene absorber of 15 to 30 times to minimize the injury of the pedestrian during a pedestrian collision.

또한, 상기 고발포 업소버(22)와 지지용 빔(30) 사이에 개재되는 고밀도의저발포 업소버(24)는 10 배품 이하의 폴리에틸렌 재질로 제조되어 자동차의 충돌시 차체를 보호할 수 있다.In addition, the high-density low-absorber 24 interposed between the high-foam absorber 22 and the support beam 30 is made of a polyethylene material of 10 times or less to protect the vehicle body during a collision of the vehicle.

따라서, 범퍼커버(20) 내부에 장착되는 지지용 빔(30)의 단면적을 최소화하여 범퍼커버(20)와 지지용 빔(30) 사이의 충격흡수 공간을 최대화하고, 상기 범퍼커버(20)와 지지용 빔(30) 사이에 고발포 업소버(22)와 저발포 업소버(24)를 개재하여 자동차의 충돌시 충돌 에너지를 고발포 업소버(22)와 저발포 업소버(24) 및 지지용 빔(30)의 경로를 따라 3중으로 흡수하여 차체보호와 보행자 보호를 동시에 수행할 수 있다.Therefore, the cross-sectional area of the support beam 30 mounted inside the bumper cover 20 is minimized to maximize the shock absorption space between the bumper cover 20 and the support beam 30, and the bumper cover 20 and The high-energy absorber 22 and the low-foam absorber 24 and the support beam 30 are provided with collision energy during collision of the vehicle through the high-foam absorber 22 and the low-foam absorber 24 between the support beams 30. It can be absorbed in three directions along the path of) to simultaneously carry out bodywork protection and pedestrian protection.

이상에서 상술한 바와 같이, 본 발명에 따른 자동차용 범퍼의 구조에 의하면 범퍼커버와 최소단면을 갖는 지지용 빔 사이에 폴리에틸렌 재질의 고발포 업소버와 저발포 업소버를 이중으로 개재하여 자동차의 충돌시 충돌 에너지를 3중으로 흡수하여 차체도 보호하고 보행자의 상해치도 최소화 할 수 있는 효과가 있다.As described above, according to the structure of the bumper for a vehicle according to the present invention, a collision between a bumper cover and a support beam having a minimum cross section between a high foamed absorber and a low foamed absorber made of polyethylene is doubled. By absorbing energy in threefold, it protects the body and minimizes the injury of pedestrians.
