Abstract

PURPOSE: An impact energy absorbing structure of a front-end module carrier is provided to reduce the cost for manufacturing a vehicle body, the weight of the vehicle, and working time by integrally forming a bumper lower end-supporting member to the lower end of a front-end module carrier made from plastic materials. CONSTITUTION: An impact energy absorbing structure of a front-end module carrier(100) for minimizing the injury degree for lower body parts of pedestrians in colliding the pedestrians with a vehicle body integrally forms a bumper lower end-supporting member(200) formed in a beehive-shape to easily absorb impact to the lower end of the front-end module carrier made from plastic materials without combining the bumper lower end supporting member to a front lower end horizontal member or a front rail by a bolt.

프론트 엔드 모듈 캐리어의 충격 에너지 흡수 구조 {A Collision energy absorption structure of Front end module career}A collision energy absorption structure of front end module career

본 발명은 보행자와의 충돌시 충격 에너지를 효율적으로 흡수하여 보행자의 하지 상해치를 최소화시킬 수 있는 프론트 엔드 모듈 캐리어의 충격 에너지 흡수구조에 관한 것으로서, 보다 상세하게는 프론트 엔드 모듈 캐리어의 하단부에 충격 흡수가 용이한 벌집 모양으로 성형된 범퍼 하단 지지부재를 일체화 성형하므로써 추가적인 차량 제작원가와 차체 중량 및 작업 공수의 증가 없이 보행자의 하지 상해치를 최소화시킬 수 있는 프론트 엔드 모듈 캐리어의 충격 에너지 흡수 구조에 관한 것이다.The present invention relates to a shock energy absorbing structure of a front end module carrier that can efficiently absorb impact energy when colliding with a pedestrian to minimize the injuries of the lower part of the pedestrian. The present invention relates to an impact energy absorbing structure of a front end module carrier which can minimize the injuries of pedestrians without additional vehicle manufacturing cost, body weight, and workmanship by integrally forming a bumper lower support member formed into an easy honeycomb shape. .

일반적으로, 자동차와 보행자의 충돌시 차량의 프론트 범퍼에 의해 보행자의 무릎에 상해가 가해지는데, 이를 최소화하기 위해 보행자의 무릎 아랫부분을 범퍼 하단이 충돌 에너지를 흡수하면서 효과적으로 밀어주면 보행자의 무릎 꺽임량이 감소되어 보행자의 하지 상해치를 최소화시킬 수 있다.In general, in the collision of a car and a pedestrian, the front bumper of the vehicle injuries the pedestrian's knee. To minimize this, the lower part of the pedestrian's knee effectively pushes the bumper's knee while absorbing the collision energy. It can be reduced to minimize the pedestrian injury.

이를 위해서는 차량의 프론트 범퍼 하단부를 지지하여야만 하는데, 기존 차량의 경우 도 1과 도 2 및 도 3에 각각 도시한바와 같이, 보행자 보호를 위해 범퍼 하단을 지지해 주는 범퍼 하단 지지부재가 프론트 엔드 모듈 캐리어(1)에 형성되어 있지 않거나, 프론트 하단 횡부재(2)나 프론트 레일(3)에 범퍼 하단 지지부재(4)가 볼트를 이용하여 체결되는 구조로 형성되어 있다.To this end, the front bumper bottom portion of the vehicle must be supported. As shown in FIGS. 1, 2, and 3, in the case of the existing vehicle, the front end module carrier includes a bumper bottom support member that supports the bottom of the bumper for pedestrian protection. It is not formed in (1), or the bumper lower support member 4 is fastened to the front lower horizontal member 2 or the front rail 3 using a bolt.

그러나, 상기와 같이 보행자의 하지(L) 상해치를 저감시키기 위해 프론트 하단 횡부재 또는 프론트 레일에 범퍼 하단 지지부재를 볼트를 이용하여 체결하는 것은 차량 제작원가와 차체 중량이 증대되고, 차체 조립 공정시 작업공수가 증가되는 문제점을 가지고 있다.However, as described above, fastening the bumper lower support member to the front lower horizontal member or the front rail by using a bolt in order to reduce the injuries of the lower limb (L) of the pedestrian increases the vehicle manufacturing cost and the weight of the vehicle body. There is a problem of increased workmanship.

상술한 바와 같은 문제점을 해결하기 위하여 안출된 본 발명의 목적은 차량제작 원가와 차체 중량 및 작업 공수의 증가 없이 보행자와의 충돌시 보행자의 하지 상해치를 최소화시키고자 하는데 있다.An object of the present invention devised to solve the problems as described above is to minimize the injuries of the pedestrian in the event of a collision with the pedestrian without increasing the vehicle manufacturing cost, the weight of the body and the number of work.

전술한 바와 같은 본 발명의 목적을 달성하기 위해서 에너지 흡수가 용이한 벌집 모양으로 성형된 범퍼 하단 지지부재를 플라스틱 재질로 제작된 프론트 엔드 모듈 캐리어 하단에 일체화 성형시킨 프론트 엔드 모듈 캐리어의 충격 에너지 흡수 구조를 제공한다.In order to achieve the object of the present invention as described above, the impact energy absorbing structure of the front end module carrier integrally molded to the lower end of the front end module carrier made of plastic material formed of a bumper lower support member formed in a honeycomb shape to facilitate energy absorption To provide.
