본 발명은 자동차용 범퍼빔에 관한 것으로, 더욱 상세하게는 플라스틱(plastic)재로 이루어진 범퍼빔의 상·하측 보강리브 사이에 스틸(steel)재의 강성부재가 결합됨으로서 플라스틱(plastic)재로 이루어진 범퍼빔의 강성 및 완충효과가 향상된 자동차용 범퍼빔에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bumper beam for automobiles, and more particularly, to a bumper beam made of plastic by combining a rigid member of steel material between upper and lower reinforcement ribs of a bumper beam made of plastic. The present invention relates to a bumper beam for automobiles having improved rigidity and cushioning effect.

일반적으로 자동차에는 충돌 시 발생되는 충격력을 흡수하여 차량 및 탑승자 등을 보호하기 위해 차체의 전방 및 후방에 범퍼가 장착된다.BACKGROUND OF THE INVENTION [0002] Generally, a bumper is mounted on the front and rear of a vehicle body to protect a vehicle and an occupant by absorbing an impact force generated in a collision.

상기 범퍼는 외면을 이루는 범퍼커버와, 상기 범퍼커버를 통해 충격이 전달되는 범퍼빔으로 구성되는데, 상기 범퍼빔은 자동차에 전달되는 충격을 완충하는 것으로 충격력이 클 경우에는 그 충격력을 효과적으로 완충하도록 변형되고, 충격력이 적을 경우에는 변형되지 않거나 변형량을 최소화하도록 하는 역할을 한다.The bumper is composed of a bumper cover forming an outer surface and a bumper beam through which the impact is transmitted through the bumper cover. The bumper beam cushions an impact transmitted to an automobile. When the impact force is large, And when the impact force is small, it does not deform or minimizes the deformation amount.

도 1은 종래의 범퍼빔(100)의 장착을 나타낸 것으로, 도시된 바와 같이 범퍼빔(100)은 차체의 사이드 멤버(110)에 고정된 캐리어(120)의 전면에 장착된다.1 shows a mounting of a conventional bumper beam 100 in which a bumper beam 100 is mounted on the front side of a carrier 120 fixed to a side member 110 of a vehicle body.

상기 범퍼빔(100)은 전술한 바와 같이 충격의 완충 역할을 하는 것으로, 수직방향으로 소정의 높이를 갖는 전면부(110)와, 상기 전면부(110)의 상단부와 하단부로부터 연장되어 상기 전면부(110)의 후방으로 절곡된 상·하측지지부(112, 113)로 되어 자동차의 폭방향으로 길게 형성된다.As described above, the bumper beam 100 functions as a shock buffer. The bumper beam 100 includes a front portion 110 having a predetermined height in a vertical direction, and a front portion 110 extending from an upper end portion and a lower end portion of the front portion 110, Upper and lower support portions 112 and 113 bent rearwardly of the body 110, and are formed to be long in the width direction of the automobile.

상기 전면부(110)와 상·하측지지부(112, 113)는 충격으로부터 차량 및 탑승자의 보호를 위해 소정의 강성을 갖도록 스틸(steel)재로 형성되는데, 상기 범퍼빔(100)이 스틸(steel)재로 이루어짐에 따라 소정의 강성이 확보된다는 장점이 있으나, 중량이 커져 자동차의 중량 및 연비에 악영향을 끼친다는 문제점이 있으며, 스틸(steel)재의 특성상 완충력이 떨어져 충격력이 그대로 탑승자에게 전달된다는 문제점이 있었다.The front portion 110 and the upper and lower support portions 112 and 113 are formed of steel so as to have a predetermined rigidity for protecting the vehicle and the passenger from impact. The bumper beam 100 is made of steel, However, the weight of the automobile is adversely affected by the weight of the automobile and the fuel consumption of the automobile, and the buffering force is reduced due to the characteristics of the steel material, so that the impact force is transmitted to the occupant as it is .

이와 같은 문제점을 극복하고자 플라스틱(plastic)재로 이루어진 범퍼빔이 개시되었다. 상기 범퍼빔이 플라스틱(plastic)재로 이루어짐에 따라 범퍼빔의 경량화 및 자동차의 경량화는 가능하나 충격을 완충할만한 강성이 확보되지 않아 완충 역할을 하는데 적합하지 못하다는 문제점이 발생하였다.In order to overcome such a problem, a bumper beam made of a plastic material has been disclosed. Since the bumper beam is made of a plastic material, it is possible to reduce the weight of the bumper beam and the weight of the automobile, but the stiffness sufficient to cushion impact is not ensured, which is not suitable for buffering.

본 발명은 상기의 문제점을 해결하기 위하여 안출된 것으로서, 본 발명의 목적은 충격의 완충을 위해 소정의 강성이 보장됨은 물론 완충효과가 향상된 자동차용 범퍼빔을 제공하는 것이다.The present invention has been made to solve the above problems, and an object of the present invention is to provide a bumper beam for automobiles, which has a certain rigidity as well as a buffering effect, which is ensured for shock absorbing.

본 발명의 또 다른 목적은 플라스틱(plastic)재의 범퍼빔과 스틸(steel)재의 강성부재 사이에 고정구조가 단순화 되어 제작 및 유지보수가 용이한 자동차용 범퍼빔을 제공하는 것이다.Still another object of the present invention is to provide a bumper beam for automobiles, which is easy to manufacture and maintain, by simplifying a fixing structure between a plastic bumper beam and a rigid member of steel material.

본 발명은 또 다른 목적은 플라스틱(plastic)재의 보강리브에 의해 충격의 분산 및 충격의 흡수가 뛰어난 자동차용 범퍼빔을 제공하는 것이다.Another object of the present invention is to provide a bumper beam for automobiles which is excellent in dispersion of shock and absorption of impact by reinforcing ribs made of plastic.

수직방향으로 소정의 높이를 갖는 전면부와, 상기 전면부의 상단부와 하단부로부터 후방으로 연장된 상·하측지지부로 이루어져 자동차의 폭방향으로 길게 형성된 자동차용 범퍼빔에 있어서,In the bumper beam for automobiles formed in the width direction of the vehicle consisting of a front portion having a predetermined height in the vertical direction, and the upper and lower support portions extending rearward from the upper end and the lower end of the front portion,

상기 전면부와 상·하측지지부는 플라스틱(plastic)재로 이루어지고, 상기 상측지지부와 하측지지부의 대향면에는 플라스틱(plastic)재의 상·하측 보강리브 가 각각 돌출 형성되며, 상기 상·하측 보강리브 사이에는 자동차의 폭방향으로 길이를 갖는 스틸(steel)재의 강성부재가 구비된 것을 특징으로 한다.The front part and the upper and lower support parts are made of plastic, and the upper and lower reinforcement ribs of the plastic material are formed to protrude from opposite surfaces of the upper and lower support parts, respectively, between the upper and lower reinforcement ribs. It characterized in that the rigid member of the steel (steel) having a length in the width direction of the vehicle is provided.

여기서, 상기 강성부재는 원형의 단면을 갖는 봉 또는 중공관으로 이루어지며, 상기 상·하측 보강리브의 후방측 단부에는 상기 강성부재의 외경보다 작은 간격으로 이격된 이탈방지부가 각각 돌출 형성된 것을 특징으로 한다.Here, the rigid member is made of a rod or a hollow tube having a circular cross section, the rear end portions of the upper and lower reinforcing ribs are characterized in that each of the separation prevention spaced apart at intervals smaller than the outer diameter of the rigid member is formed. do.

한편, 상기 전면부의 수직방향 중앙부는 전방으로 돌출 형성되며, 상기 상·하측 보강리브의 최전방은 서로 연결됨과 동시에 상기 전면부의 내측면에 맞닿도록 연장 형성된 것을 특징으로 한다.On the other hand, the vertical center portion of the front portion protrudes forward, the foremost of the upper and lower reinforcing ribs are connected to each other and at the same time characterized in that it is formed to extend to contact the inner surface of the front portion.

상술한 바와 같이 본 발명에 의하면, 플라스틱(plastic)재의 범퍼빔에 소정의 강성을 갖는 스틸(steel)재의 강성부재가 결합됨으로서 상기 범퍼빔의 하중은 감소되는 반면 상기 범퍼빔의 강성 및 완충효과는 보다 향상된다는 특유의 작용효과가 있다.As described above, according to the present invention, the rigid member of the steel material having a predetermined rigidity is coupled to the bumper beam of the plastic material, so that the load of the bumper beam is reduced while the stiffness and buffering effect of the bumper beam are reduced. There is a distinctive effect of improving.

이하, 상기한 바와 같은 구성을 가지는 본 발명에 의한 자동차용 범퍼빔에 대해서 첨부된 도면을 참고하여 상세하게 설명한다.Hereinafter, a bumper beam for a vehicle according to the present invention having the configuration as described above will be described in detail with reference to the accompanying drawings.

도 3은 본 발명의 자동차용 범퍼빔의 전면을 나타낸 사시도이고, 도 4는 본 발명의 자동차용 범퍼빔의 후면을 나타낸 사시도이며, 도 5는 본 발명의 자동차용 범퍼빔의 단면을 나타낸 단면도이고, 도 6은 본 발명의 자동차용 범퍼빔의 분해사시도이다.Figure 3 is a perspective view showing the front of the bumper beam for automobiles of the present invention, Figure 4 is a perspective view showing a rear of the bumper beam for cars of the present invention, Figure 5 is a cross-sectional view showing a cross section of the bumper beam for cars of the present invention. 6 is an exploded perspective view of a bumper beam for automobiles of the present invention.

도 3 내지 도 6은 본 발명의 범퍼빔을 나타낸 도면으로서, 도시된 바와 같이 본 발명의 범퍼빔은 수직방향으로 소정의 높이를 갖는 전면부(10)와, 상기 전면부(10)의 상단부로부터 후방으로 연장된 상측지지부(12), 및 상기 전면부(10)의 하단부로부터 후방으로 연장된 하측지지부(13)로 이루어져 자동차의 폭방향으로 길게 형성되며, 상기 상측지지부(12)와 하측지지부(13)가 서로 마주보는 대향면에는 상기 상·하측지지부(12, 13)로부터 상·하측 보강리브(21, 22)가 각각 돌출 형성된다.3 to 6 are views showing the bumper beam of the present invention, as shown in the bumper beam of the present invention, which has a predetermined height in a vertical direction, and from an upper end of the front part 10. The upper support portion 12 extending rearward, and the lower support portion 13 extending rearward from the lower end of the front portion 10 is formed long in the width direction of the vehicle, the upper support portion 12 and the lower support portion ( The upper and lower reinforcing ribs 21 and 22 protrude from the upper and lower support portions 12 and 13, respectively, on opposite surfaces 13) facing each other.

이때, 상기 전면부(10)와 상·하측지지부(12, 13) 및 상·하측 보강리브(21, 22)는 하중이 적으며 성형이 매우 용이한 플라스틱(plastic)재로 이루어짐이 바람직하다.At this time, the front portion 10, the upper and lower support portions 12 and 13, and the upper and lower reinforcement ribs 21 and 22 are preferably made of a plastic material having a small load and very easy molding.

상기 상·하측 보강리브(21, 22) 사이에는 자동차의 폭방향으로 길이를 갖는 강성부재(30)가 구비되는데, 상기 강성부재(30)는 상기 상·하측 보강리브(21, 22)를 비롯한 상·하측지지부(12, 13) 및 전면부(10)와는 달리 소정의 강성이 보장되는 스틸(steel)재로 이루어진다.Between the upper and lower reinforcing ribs (21, 22) is provided with a rigid member 30 having a length in the width direction of the vehicle, the rigid member 30, including the upper and lower reinforcing ribs (21, 22) Unlike the upper and lower support parts 12 and 13 and the front part 10, it is made of a steel material having a predetermined rigidity.

상술한 바와 같이 자동차의 전방에 소정의 높이를 갖는 전면부(10) 및 상기 전면부(10)로부터 연장된 상·하측지지부(12, 13)와 상기 상·하측지지부(12, 13)로부터 돌출된 상·하측 보강리브(21, 22)가 경량이고 성형이 손쉬운 플라스틱(plastic)재로 이루어짐에 따라 제작이 용이할 뿐만 아니라 하중이 감소되어 자동차의 연비 향상에 도움이 된다는 장점이 있으며, 상기 상·하측 보강리브(21, 22) 사이에 소정의 강성을 갖는 스틸(steel)재의 상기 강성부재(30)가 결합됨에 따라 상기 전면부(10)와 상·하측지지부(12, 13) 및 상·하측 보강리브(21, 22)를 형성하는 플라스틱(plastic)재의 부족한 강성이 보강됨으로써 범퍼빔의 강성 및 완충력이 향상된다는 장점이 있다.As described above, the front part 10 having a predetermined height in front of the vehicle, and the upper and lower support parts 12 and 13 extending from the front part 10 and the upper and lower support parts 12 and 13 protrude. As the upper and lower reinforcing ribs 21 and 22 are made of a plastic material that is light in weight and easy to mold, it is easy to manufacture and the load is reduced to help improve fuel efficiency of the vehicle. As the rigid member 30 of steel material having predetermined rigidity is coupled between the lower reinforcing ribs 21 and 22, the front part 10, the upper and lower support parts 12 and 13, and the upper and lower parts. The insufficient rigidity of the plastic material forming the reinforcing ribs 21 and 22 may be reinforced, thereby improving the rigidity and the buffering force of the bumper beam.

상기 상·하측 보강리브(21, 22)는 상기 강성부재(30)가 고정되도록 다수개의 리브로 이루어지는데, 충격의 흡수 및 분산이 용이하도록 사선형의 이루어짐이 보다 바람직하다. 또, 사선형의 상기 상·하측 보강리브(21, 22) 사이에 결합되는 상기 강성부재(30)는 도 5에서 참조되는 바와 같이 원형 단면을 갖는 봉이나 중공 관으로 이루어짐이 바람직하다.The upper and lower reinforcing ribs 21 and 22 may be formed of a plurality of ribs to fix the rigid member 30, and it is more preferable that the upper and lower reinforcing ribs 21 are formed in a diagonal shape so as to easily absorb and disperse the impact. In addition, the rigid member 30 coupled between the diagonal upper and lower reinforcing ribs 21 and 22 is preferably made of a rod or a hollow tube having a circular cross section as shown in FIG. 5.

여기서 상기 상·하측 보강리브(21, 22)의 후방측 단부에는 상기 강성부재(30)의 외경보다 작은 간격으로 이격되도록 이탈방지부(23)가 각각 돌출 형성된다. The rear end portions of the upper and lower reinforcing ribs 21 and 22 are protruded from the separation prevention parts 23 so as to be spaced apart from each other at intervals smaller than the outer diameter of the rigid member 30.

이처럼 상기 강성부재(30)가 원형의 단면을 갖는 봉이나 중공관으로 이루어지고, 상기 강성부재(30)를 고정하는 상·하측 보강리브(21, 22)의 후방측 단부에 상기 강성부재(30)의 외경보다 작은 간격으로 이격된 이탈방지부(23)가 돌출 형성됨에 따라 상기 강성부재(30)는 상기 상·하측 보강리브(21, 22) 사이에 범퍼빔의 길이방향으로 슬라이딩 결합되거나, 상기 범퍼빔의 후방으로부터 전방으로 이동되어 스냅-인(snap-in) 결합될 수 있는 등, 결합구조가 단순화되어 유지보수는 물론 제작이 간편하다는 특징이 있다.As described above, the rigid member 30 is formed of a rod or a hollow tube having a circular cross section, and the rigid member 30 is formed at the rear end portions of the upper and lower reinforcing ribs 21 and 22 that fix the rigid member 30. As the separation prevention part 23 spaced apart from each other by an interval smaller than the outer diameter of the protrusion is formed, the rigid member 30 is slidably coupled in the longitudinal direction of the bumper beam between the upper and lower reinforcing ribs 21 and 22, Since the bumper beam may be moved forward from the rear of the bumper beam to be snap-in coupled, the coupling structure may be simplified to simplify maintenance and manufacturing.

아울러, 플라스틱(plastic)재로 이루어진 상기 상·하측 보강리브(21, 22)로부터 스틸(steel)재로 이루어진 상기 강성부재(30)의 분리가 쉬워 상기 범퍼빔이 수명을 하다여 폐기되는 과정에서 상기 스틸(steel)재와 플라스틱(plastic)재의 분리작업이 손쉽게 이루어져 자원의 재활용이 용이하다는 장점이 있다.In addition, it is easy to separate the rigid member 30 made of steel from the upper and lower reinforcement ribs 21 and 22 made of plastic, so that the bumper beam has a lifespan and is discarded. (Steel) and plastic (plastic) separation of the work is easy to have the advantage of easy recycling of resources.
