본 고안은 차량 충돌시에 대비한 충분한 강성을 발휘할 수 있도록 보강부재를 구비한 자동차의 범퍼 백빔에 관한 것이다.The present invention relates to a bumper back beam of an automobile having a reinforcing member so as to exhibit sufficient rigidity in case of a vehicle crash.
일반적으로 자동차의 범퍼 백빔은 차량 충돌시의 충격을 대부분 흡수해 주는 완충부재로서, 이것의 전면과 후면에는 범퍼 커버와 범퍼 스테이가 각각 장착된다.In general, a bumper back beam of a vehicle is a shock absorbing member that absorbs most of a shock in a vehicle collision, and a bumper cover and a bumper stay are mounted on the front and rear surfaces thereof.
이러한 범퍼 백빔은 최근의 차량 경량화 추세에 따라 합성수지재의 블로워 범퍼 백빔이 많이 적용되고 있으며, 첨부도면 제 2 도에서는 블로워 범퍼 백빔의 대표적인 형태를 나타내고 있다.Such a bumper back beam has been applied to a blower bumper back beam of a synthetic resin material in accordance with the recent trend of lightening the vehicle, and FIG. 2 shows a representative form of the blower bumper back beam.
즉, 기존의 블로워 범퍼 백빔(10)은 상하 폭 중심의 요홈부(11)를 사이에 두고 위아래쪽에 각각의 중공부(12)가 배치되는 구조의 단면을 갖는다.That is, the conventional blower bumper back beam 10 has a cross section of a structure in which each hollow part 12 is disposed above and below with the recess 11 of the upper and lower width centers interposed therebetween.
그러나, 이와 같은 기존의 범퍼 백빔은 자체 강성이 그다지 높지 않아 차량 충돌시의 충격에 대해 매우 취약한 면을 보여왔고, 특히 수출용 차량에 적용되는 리어 폴 테스트(Rear pole test)의 성적이 낮게 나타나 등급 판정시의 불리함을 안게 되는 등 이에 대한 개선의 필요성이 절실히 요구되어 왔다.However, such a conventional bumper backbeam has a very weak side due to its high rigidity, and is particularly vulnerable to the impact of a vehicle crash. In particular, the rear pole test applied to an export vehicle has a low grade. There is an urgent need for improvements such as the disadvantages of the city.
따라서, 본 고안은 이와 같은 점을 감안하여 안출한 것으로서, 범퍼 백빔의 후면을 받쳐줄 수 있는 스틸재의 보강부재를 구비하고, 이것의 자체강성을 이용하여 차량충돌시 충격에 대한 강성을 충분히 발휘할 수 있게 한 보강부재를 구비한 범퍼 백빔을 제공하는 데 그 목적이 있는 것이다.Accordingly, the present invention has been devised in view of such a point, and has a reinforcing member made of steel capable of supporting the rear surface of the bumper back beam, and by using its own rigidity, it can sufficiently exhibit the rigidity against impact during a vehicle crash. It is an object of the present invention to provide a bumper back beam having a reinforcing member.
이하, 첨부도면을 참조하여 본 고안을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
본 고안은 범퍼 백빔(10)의 뒷쪽에 스틸재의 보강부재(20)가 설치되는 대로 이루어지되, 상기 보강부재(20)는 백빔이 갖는 요홈부(11)의 좌우 길이 중심에 삽입 위치되는 전방돌출판(21)과, 백빔 후면의 전 길이에 걸쳐 중첩 위치되는 상하 2개의 가로 받침판(22)으로 구성된 것을 특징으로 한다.The present invention is made as the reinforcing member 20 of the steel material is installed on the back of the bumper back beam 10, the reinforcing member 20 is the front stone is inserted into the center of the left and right length of the recess 11 having the back beam It is characterized by consisting of a publication 21, and two horizontal support plates 22, which are positioned overlapping over the entire length of the back beam rear surface.
특히, 상기 전방돌출판(21)의 단면은 상기 요홈부(11)의 단면과 동일한 ㄷ자 형상으로 이루어진 것을 특징으로 한다.In particular, the cross section of the front protrusion plate 21 is characterized in that the same as the cross-section of the groove portion 11 made of the U-shape.
또한, 상기 가로받침판(22)의 양단부에는 다수의 보울트 체결구멍(23)이 형성되어 있는 것을 특징으로 한다.In addition, a plurality of bolt fastening holes 23 are formed at both ends of the horizontal support plate 22.
이를 좀더 상세히 설명하면 다음과 같다.This will be described in more detail as follows.
첨부도면 제 1 도는 본 고안에 따른 범퍼 백빔을 나타내는 사시도이다.1 is a perspective view showing a bumper back beam according to the present invention.
여기서, 도면부호 20은 보강부재를 나타낸다.Here, reference numeral 20 denotes a reinforcing member.
상기 보강부재(20)는 범퍼 백빔(10)의 요홈부(11)에 삽입되는 전방돌출판(21)과, 후면부에 중첩되는 상하 2개의 가로받침판(22)으로 구성된다.The reinforcing member 20 includes a front protrusion plate 21 inserted into the recess 11 of the bumper back beam 10, and two horizontal support plates 22 arranged on the rear surface of the bumper back beam 10.
상기 전방돌출판(21)은 ㄷ자 형상으로 절곡성형된 판체로 이루어져 있으며, 상기 가로받침판(22)은 범퍼 백빔(10)의 후면이 갖는 폭과 길이에 상응하는 크기로 된 띠편형상의 판체로 이루어져 있다.The front protrusion plate 21 is formed of a plate body bent into a U-shape, the horizontal support plate 22 is made of a strip-shaped plate of a size corresponding to the width and length of the rear surface of the bumper back beam 10. have.
본 고안의 보강부재(20)는 이러한 전방돌출판(21)과 가로받침판(22)이 일체 조합된 형태로 되어 있다.The reinforcing member 20 of the present invention has a form in which the front protrusion plate 21 and the horizontal support plate 22 are integrally combined.
이와 같은 본 고안의 보강부재(20)는 전방돌출판(21)을 이용하여 범퍼 백빔(10)의 요홈부(11)내에 끼워지면서 가로받침판(22)의 양단부에 형성되어 있는 보울트 체결구멍(23)을 통한 보울트 체결에 의해 범퍼 백빔(10)과 일체형으로 결합될 수 있게 된다.The reinforcing member 20 according to the present invention is fitted into the recess 11 of the bumper back beam 10 by using the front protrusion plate 21, and bolt fastening holes 23 formed at both ends of the horizontal support plate 22. It is possible to be integrally combined with the bumper back beam 10 by bolt fastening through).
이때의 상기 전방돌출판(21)은 요홈부(11)의 내면에 완전히 밀착된 상태로 삽입 되어 있게 되며, 상기 가로받침판(22)도 백빔 후면에 완전히 밀착된 상태로 중첩되어 있게 된다.At this time, the front protrusion plate 21 is inserted in a state of being completely in contact with the inner surface of the recess 11, the horizontal support plate 22 is also overlapped in a state of being completely in close contact with the back beam rear.
특히, 가로받침판(22)은 범퍼 백빔(10)의 후면에 장착되는 범퍼 스테이(도시되지 않음)와의 사이에서 압착될 수 있게 되므로서, 이 가로받침판(22)과 범퍼 백빔(10)간의 결착성이 더욱 강화될 수 있게 된다.In particular, the horizontal support plate 22 is able to be compressed between the bumper stay (not shown) mounted on the rear of the bumper back beam 10, thereby binding between the horizontal support plate 22 and the bumper back beam 10. This can be further strengthened.
따라서, 상기와 같이 보강부재(20)가 갖춰진 범퍼 백빔(10)의 전면에 차량 충돌시의 충격이 전해지게 되면, 이때의 범퍼 백빔(10)은 보강부재(20)와의 상호 보완적인 연계구조가 갖는 지지강성을 이용하여 충격을 1차 저감시킬 수 있게 되는 한편, 범퍼 백빔(10)의 중공부(12)와 보강부재(20)의 자체강성을 이용하여 1차 저감된 잔여 충격을 전량 흡수할 수 있게 된다. 즉, 본 고안의 완충부재(20)는 더욱 향상된 차량 충돌시의 완충기능을 발휘할 수 있게 된다.Therefore, when the impact of the vehicle collision is transmitted to the front of the bumper back beam 10 equipped with the reinforcing member 20 as described above, the bumper back beam 10 at this time has a complementary linkage structure with the reinforcing member 20 It is possible to reduce the primary shock by using the support stiffness that has, while absorbing the total amount of the residual shock reduced primarily by using the stiffness of the hollow portion 12 and the reinforcing member 20 of the bumper back beam 10. It becomes possible. That is, the shock absorbing member 20 of the present invention can exhibit a more improved shock absorbing function when the vehicle crashes.
이상에서와 같이 본 고안은 범퍼 백빔의 후면에 효과적인 강성보완이 가능한 보강부재를 설치함으로써, 차량 충돌시에 대비한 범퍼 전체의 기능 향상을 도모할 수 있는 장점이 있는 것이다.As described above, the present invention has an advantage of improving the function of the entire bumper in case of a vehicle collision by installing a reinforcing member that can effectively supplement the rigidity on the rear surface of the bumper back beam.
