본 발명은, 차량용 범퍼의 임팩트빔에 관한 것으로서, 보다 상세하게는 충격흡수 및 경량화 구조가 개선된 차량용 범퍼의 임팩트빔에 관한 것이다. The present invention relates to an impact beam of a vehicle bumper, and more particularly, to an impact beam of a vehicle bumper having improved impact absorption and light weight structure.

차량용 범퍼는 차량의 전면 및 후면에 장착되어 차량 충돌시 발생되는 충격 을 흡수함으로써, 인명과 차량을 보호하는 역할을 한다. Vehicle bumpers are mounted on the front and rear of the vehicle to absorb the impact generated when the vehicle crashes, thereby protecting people and the vehicle.

이러한 차량용 범퍼(101)의 구성은 도 1 및 도 2에 도시된 바와 같이, 범퍼(101)의 외관을 형성하는 범퍼커버(103)와, 폴리프로필렌 발포체나 우레탄 발포체 등의 충격흡수 탄성재로 형성되어 범퍼커버(103) 내측에 설치되는 업소버(105)와, 차체(120)에 고정되어 업소버(105)와 범퍼커버(103)를 지지함과 동시에 업소버(105)에서 감당하지 못하는 과도한 충격을 흡수하는 임팩트빔(110)으로 구성된다. 1 and 2, the configuration of the vehicle bumper 101 is formed of a bumper cover 103 forming the exterior of the bumper 101, and an impact absorbing elastic material such as polypropylene foam or urethane foam. And the absorber 105 installed inside the bumper cover 103 and the vehicle body 120 to support the absorber 105 and the bumper cover 103 and absorb excessive shocks that the absorber 105 cannot handle. It is composed of an impact beam (110).

이중 임팩트빔(110)은 차량에 가해지는 과도한 충격을 최대한 흡수하여 차량의 파손과 이에 따른 인명피해를 방지하는 것으로 범퍼(101)의 구성에 있어서 매우 중요한 역할을 담당하고 있다. The double impact beam 110 plays a very important role in the configuration of the bumper 101 by preventing excessive damage to the vehicle and preventing damage to the vehicle and consequent injury.

이러한 임팩트빔(110)은 폐쇄 단면이나 ㄷ자 단면을 갖는 강재로 제조되어 왔지만, 최근 연비 향상을 위한 차량의 경량화 및 컴팩트화에 부응하기 위해 내충격 특성이 우수한 GMT(Glass Mat Thermoplastic)소재를 압축 성형한 임팩트빔(110)이 많이 사용되고 있는 실정이다. The impact beam 110 has been manufactured from steel having a closed cross section or a U-shaped cross section. However, in order to meet the weight reduction and compactness of a vehicle for improving fuel efficiency, compression-molded glass mat thermoplastic (GMT) material having excellent impact resistance characteristics has been recently developed. The impact beam 110 is used a lot.

그러나, 종래 GMT 소재의 임팩트빔은 필요로 하는 충격흡수력에 대응하는 강성 및 강도를 부여하기 위해서 그 성형두께를 전체적으로 두껍게 형성해야 하기 때문에, 임팩트빔의 중량 감소 및 컴팩트화에 한계가 따르는 문제점이 있었다. However, the impact beam of the conventional GMT material has a problem that there is a limitation in reducing the weight and compactness of the impact beam because the molding thickness must be formed as a whole in order to give the rigidity and strength corresponding to the required shock absorbing force. .

또한, 성형두께의 증가에 의해서 소재의 소모량이 증가하게 됨으로, 임팩트빔의 제조비용이 증가하는 문제점이 발생하였다.In addition, since the consumption of the material is increased by increasing the molding thickness, there is a problem that the manufacturing cost of the impact beam increases.

따라서, 본 발명의 목적은, 충격흡수력이 우수하고 경량화 및 컴팩트화가 용 이하며, 제조비용을 절감할 수 있는 차량용 범퍼의 임팩트빔을 제공하는 것이다. Accordingly, it is an object of the present invention to provide an impact beam of a vehicle bumper that is excellent in shock absorption, easy to light weight and compact, and can reduce manufacturing cost.

상기 목적은, 본 발명에 따라, 상부면 및 하부면과 전면 웨브부를 갖는 소정 길이의 차량용 범퍼의 임팩트빔에 있어서, 적어도 상기 상부면과 하부면 중 어느 하나에 형성되되, 전후방 방향으로 선형 배열된 소정의 단면 형상이 상기 임팩트빔의 길이방향으로 소정의 간격을 두고 형성되어 있는 충격흡수패턴과, 적어도 상기 웨브부의 일 영역에 형성되는 보강리브를 갖는 것을 특징으로 하는 차량용 범퍼의 임팩트빔에 의해 달성된다. The object is, in accordance with the present invention, an impact beam of a vehicle bumper of a predetermined length having an upper surface and a lower surface and a front web portion, which is formed on at least one of the upper surface and the lower surface, and is linearly arranged in the front-rear direction. A predetermined cross-sectional shape is achieved by the impact beam of the bumper for a vehicle, characterized in that it has a shock absorbing pattern is formed at a predetermined interval in the longitudinal direction of the impact beam, and a reinforcing rib formed in at least one region of the web portion. do.

이때, 상기 단면 형상은 다각형 단면 또는 원호단면인 것이 효과적이다. At this time, it is effective that the cross-sectional shape is a polygonal cross section or an arc cross section.

또는, 상기 충격흡수패턴은 상기 상부면 및 하부면 판면에서 평면 투영시 원형 또는 다각형상의 평면을 가지고 돌출 되거나 함몰된 다수의 엠보싱 형상을 갖는 것이 효과적이다. Alternatively, the shock absorbing pattern is effective to have a plurality of embossed shapes protruded or recessed with a circular or polygonal plane when projecting from the upper surface and the lower surface plate surface.

이때, 상기 충격흡수패턴은 상기 상부면과 하부면의 중앙영역에 형성되어 있는 것이 보다 바람직하다. In this case, the impact absorption pattern is more preferably formed in the central region of the upper surface and the lower surface.

또한, 상기 보강리브는 상기 웨브부의 중앙영역에서 상기 임팩트빔의 길이방향을 따라 적어도 하나가 돌출되어 있는 것이 보다 효과적이다. In addition, it is more effective that at least one reinforcing rib protrudes along the longitudinal direction of the impact beam in the central region of the web portion.

이하에서는 첨부된 도면을 참고하여 본 발명에 대해서 상세하게 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the present invention.

도 3은 본 발명에 따른 차량용 범퍼의 임팩트빔 사시도이고, 도 4는 도 3의 Ⅳ-Ⅳ선에 따른 임팩트빔의 단면도이다. 이들 도면에 도시된 바와 같이, 본 발명에 따른 차량용 범퍼의 임팩트빔(10)은 적어도 상하부면(11,13) 중앙영역에 충격흡수패턴(20)이 형성되어 있고, 임팩트빔(10)의 웨브부(15) 내측에 보강리브(30)가 형성되어 있는 ㄷ자 단면 구조를 갖도록 내충격 특성이 우수한 GMT등의 소재로 성형된다.3 is a perspective view of an impact beam of a vehicle bumper according to the present invention, and FIG. 4 is a cross-sectional view of the impact beam taken along line IV-IV of FIG. 3. As shown in these figures, the impact beam 10 of the bumper for a vehicle according to the present invention has a shock absorbing pattern 20 is formed at least in the center region of the upper and lower surfaces 11, 13, the web of the impact beam 10 It is molded from a material such as GMT having excellent impact resistance properties so as to have a U-shaped cross-sectional structure in which the reinforcing rib 30 is formed inside the part 15.

충격흡수패턴(20)은 임팩트빔(10)의 상하부면(11,13) 중앙영역에서 전후방 폭 방향으로 선형 배열된 소정 형상의 단면패턴이 임팩트빔(10)의 길이방향으로 소정의 간격을 두고 형성되어 있는 구조를 가지고 있다. The shock absorbing pattern 20 is a cross-sectional pattern of a predetermined shape linearly arranged in the front and rear width directions in the center region of the upper and lower surfaces 11 and 13 of the impact beam 10 at a predetermined interval in the longitudinal direction of the impact beam 10. It has a formed structure.

이때, 충격흡수패턴(20)의 단면형상은 도 3 내지 도 7에 도시된 바와 같이, 삼각형상 등의 다각형 단면 형상이거나 도 8 및 도 9에 도시된 바와 같이, 원호단면 형상을 가지고 돌출되거나 함몰 형성될 수 있다. 또한, 충격흡수패턴(20)의 형상은 도 10 및 도 11에 도시된 바와 같이, 평면 투영시 원형 또는 다각형상의 평면을 가지고 돌출 되거나 함몰된(미도시) 다수의 엠보싱 형상으로 형성될 수도 있다. At this time, the cross-sectional shape of the shock absorbing pattern 20 is a polygonal cross-sectional shape, such as a triangular shape, as shown in Figures 3 to 7, or as shown in Figures 8 and 9, protruding or recessed with an arc cross-sectional shape. Can be formed. In addition, the shape of the shock absorbing pattern 20 may be formed in a plurality of embossed shapes protruded or recessed (not shown) with a circular or polygonal plane in planar projection, as shown in FIGS. 10 and 11.

이러한 충격흡수패턴(20)은 임팩트빔(10)의 판면에 단면 2차 모멘트 및 단면계수를 증가시킴으로써, 임팩트빔(10)의 강성과 강도를 증대시킨다. 따라서, 임팩트빔(10)을 성형할 때 충격흡수패턴(20) 형성에 따른 임팩트빔(10)의 강도 및 강성 증가분 만큼의 성형두께 및 크기를 절감하여 임팩트빔(10)의 중량을 줄일 수 있다. The impact absorption pattern 20 increases the stiffness and strength of the impact beam 10 by increasing the cross-sectional secondary moment and the cross-sectional coefficient on the plate surface of the impact beam 10. Therefore, when forming the impact beam 10, the weight of the impact beam 10 may be reduced by reducing the molding thickness and size by the increase in the strength and stiffness of the impact beam 10 according to the impact absorption pattern 20. .

여기서, 충격흡수패턴(20)은 전술한 바와 같이, 차량의 정면충돌에 효과적으 로 대응할 수 있도록 임팩트빔(10)의 중앙영역 상하부면(11,13)에 형성될 수도 있으며, 도시하지는 않았지만 임팩트빔(10)의 상하면의 길이방향 전 영역에 형성될 수도 있다. 물론, 충격흡수패턴(20)의 형상과 형성위치는 필요에 따라서 변경될 수 있다. Here, the shock absorbing pattern 20 may be formed on the upper and lower surfaces 11 and 13 of the central region of the impact beam 10 so as to effectively respond to the frontal collision of the vehicle as described above. It may be formed in the entire longitudinal region of the upper and lower surfaces of the beam 10. Of course, the shape and formation position of the shock absorbing pattern 20 can be changed as necessary.

한편, 보강리브(30)는 임팩트빔(10)의 전면을 형성하는 웨브부(15)의 적어도 내측 중앙영역에서 임팩트빔(10)의 길이방향을 따라 돌출되어 있는 구조를 갖는다. 이 보강리브(30)는 임팩트빔(10)의 상하 높이 크기에 따라 복수의 보강리브(30)로 형성될 수도 있으며, 임팩트빔(10)의 양측 길이방향 전 구간에 걸쳐 형성될 수도 있다. 물론, 보강리브(30)의 형상과 형성위치는 필요에 따라 변경될 수 있다. On the other hand, the reinforcing rib 30 has a structure that protrudes along the longitudinal direction of the impact beam 10 in at least an inner central region of the web portion 15 forming the front surface of the impact beam (10). The reinforcing ribs 30 may be formed of a plurality of reinforcing ribs 30 according to the vertical height of the impact beam 10, and may be formed over the entire lengthwise sides of the impact beam 10. Of course, the shape and formation position of the reinforcing rib 30 can be changed as necessary.

이러한 보강리브(30)는 직접적으로 충격이 가해지는 임팩트빔(10)의 웨브부(15)의 구조적 강도와 강성을 보강함으로써, 임팩트빔(10)을 성형할 때 보강리브(30)에 의한 임팩트빔(10)의 강도 및 강성 증가분 만큼의 성형두께 및 크기를 절감하여 임팩트빔(10)의 중량을 줄일 수 있다. This reinforcement rib 30 is reinforced by the structural strength and rigidity of the web portion 15 of the impact beam 10 is directly impacted, the impact by the reinforcement ribs 30 when forming the impact beam 10 The weight of the impact beam 10 may be reduced by reducing the molding thickness and size by the increase in the strength and rigidity of the beam 10.

이러한 구조를 갖는 본 발명에 따른 차량용 범퍼의 임팩트빔(10)에 대해 충돌해석 프로그램인 Pam-Crash를 이용하여 충돌 시뮬레이션을 실행해 본 결과가 아래의 표-1에 개시되어 있다.The results of the collision simulation using the impact analysis program Pam-Crash for the impact beam 10 of the vehicle bumper having the above structure are shown in Table-1 below.

여기서, 비교대상인 종래 임팩트빔(110)은 본 발명에 따른 임팩트빔(10)에서 충격흡수패턴(20)과 보강리브(30)의 구조를 제외한 성형두께 및 크기 등의 규격이 동일하다. 그리고, 충격하중은 임팩트빔(10,110)의 비교적 소형 차량이 정면 중앙에서 5마일/h로 충돌될 때 발생하는 충격하중으로 가해진 실험이다. Here, the conventional impact beam 110 to be compared is the same as the molding thickness and size in the impact beam 10 according to the present invention except for the structure of the shock absorbing pattern 20 and the reinforcing rib (30). In addition, the impact load is an experiment applied to the impact load generated when the relatively small vehicle of the impact beams 10 and 110 collides at 5 miles / h in the front center.
