본 발명은 범퍼용 에너지 업소버에 관한 것으로, 더 상세하게는 부품 자체의 중량을 줄이면서 성형성을 개선하고, 충격 에너지 흡수기능이 우수하면서도 원가를 절감시킬 수 있도록 발명된 것이다.The present invention relates to an energy absorber for a bumper, and more particularly, to improve the formability while reducing the weight of the component itself, and is invented to reduce the cost while excellent impact energy absorption function.

일반적으로, 자동차의 전후부에 설치되는 범퍼외피의 내부에는 보강용 에너지업소버가 설치되어 차량을 운행중 충돌 및 추돌사고가 발생하는 경우 충격에너지를 효과적으로 흡수하여 차실에 탑승한 승원이 충격에너지에 의해 부상당하는 것이 억제되도록 하고 있다.In general, a reinforcement energy absorber is installed inside the bumper shell installed at the front and rear of the vehicle, and in the event of a collision and a collision accident while driving the vehicle, the crew occupied by the impact energy is effectively absorbed by the impact energy. It is trying to be restrained.

최근에는, 다양한 차종 사이에서 발생되는 충돌 사고시 범퍼부의 높이 차이로 인하여 차량간 슬라이딩 현상이 발생되어 차량 손상 과다 및 이로 인한 수리비용 상승이 문제점으로 대두되고 있다.Recently, due to the difference in the height of the bumper in the collision between the various types of vehicles caused by the phenomenon of sliding between the vehicle has caused a problem of excessive damage to the vehicle and the resulting increase in repair costs.

그리고, 연료비용 상승으로 차량의 동력 성능 개선에 대한 소비자의 요구가 날로 증가하여 연비 개선을 위해 보다 충격 흡수능력이 우수하면서도 중량이 가벼운 에너지업소버를 요구하고 있다.In addition, as the fuel cost increases, the demand for consumers to improve the power performance of the vehicle increases day by day, demanding more energy-absorber with lighter weight and better shock absorption capacity to improve fuel efficiency.

종래 에너지업소버(30)는 플라스틱 사출물로 제작되며, 도 1에서 도시한 바와 같이 스틸재의 보강빔(20) 전방에 부착되며, 에너지업소버(30)는 범퍼외피의 형상을 따라 수직 단면이 'ㄷ' 형으로 상하 각각 성형된다.The conventional energy absorber 30 is made of a plastic injection molding, and is attached to the front of the reinforcing beam 20 of the steel material, as shown in Figure 1, the energy absorber 30 has a vertical cross-section along the shape of the bumper shell 'c' Each mold is molded up and down.

도 1에서 도시한 바와 같은 종래 에너지업소버(30)는 그 단면이 오픈 구조로 저속 충돌시 단면 변형이 쉽게 발생된다.As shown in FIG. 1, the conventional energy absorber 30 has an open structure in which a cross-sectional deformation is easily generated during a low-speed collision.

따라서, 충격 에너지 흡수율이 적어 변형량 증가로 인해 범퍼 성능이 저하되고 차량의 상관 부품 손상을 유발하게 된다.Accordingly, the impact energy absorption rate is low, resulting in a decrease in bumper performance due to an increase in deformation amount and causing damage to a correlated part of a vehicle.

그리고, 도 2에서와 같이 빔 위치기준 높이가 높은 차량과 충돌시에는 상부에서 집중적으로 변형되고, 높이가 낮은 차량과 충돌시에는 속도에 의한 슬라이딩 발생으로 상호 차량에 손상이 과다하게 발생하였던 것이다.In addition, as shown in FIG. 2, when the vehicle collides with the vehicle having a high beam position reference height, the vehicle is deformed intensively in the upper portion, and when the vehicle collides with the vehicle having a low height, the vehicle is damaged due to the sliding caused by the speed.

결과적으로, 에너지업소버(30)의 상, 하부 형상 부족으로 다른 높이의 차종과 충돌시 손상 방지를 위한 지지 구조기능을 발휘하지 못하여 충돌에너지 흡수기능이 상실되어 차량이 과다 손상되는 원인이 되는 등 문제점이 있었던 것이다.As a result, the energy absorber 30 fails to exhibit a support structure for preventing damage when colliding with a vehicle of a different height due to a lack of upper and lower shapes of the energy absorber 30, resulting in a loss of a collision energy absorbing function and causing excessive damage to the vehicle. This was there.

또, 에너지업소버(30) 단면 형상이 범퍼 외피의 상, 하단부를 지지하지 못하여 범퍼의 꿀렁거림이 발생되는데, 이를 방지하기 위해 범퍼 상단이나 하단부에 별도의지지 구조물을 추가해야 하므로 부품수와 조립 공정수 증가로 인해 원가와 차량 전체의 중량이 상승되는 문제점도 있었다.In addition, the cross section of the energy absorber 30 does not support the upper and lower portions of the bumper shell, so bumping of the bumper occurs. In order to prevent this, a separate supporting structure must be added to the upper or lower portion of the bumper, so that the number of parts and the assembly process Due to the increase in number, the cost and weight of the entire vehicle were also increased.

본 발명의 목적은 충격 흡수를 위한 보강용 리브를 보강빔에 원하는 개수와 설계 간격으로 배치하여 성형성을 증대할 수 있도록 한 범퍼용 에너지 업소버를 제공하는데 있다.SUMMARY OF THE INVENTION An object of the present invention is to provide an energy absorber for a bumper in which reinforcing ribs for shock absorption are arranged on a reinforcing beam at a desired number and design interval to increase moldability.

본 발명의 다른 목적은, 다른 높이의 차종과 충돌시 발생되는 슬라이딩 현상 및 커버 꿀렁 거림을 방지할 수 있는 범퍼용 에너지 업소버를 제공하는데 있다.Another object of the present invention is to provide an energy absorber for a bumper that can prevent sliding phenomenon and cover slack caused when colliding with a vehicle of different height.

본 발명의 또 다른 목적은 저속 충돌시 단면 변형에 의한 흡수율을 향상시키고 차량 손상을 감소할 수 있는 범퍼용 에너지 업소버를 제공하는데 있다.It is still another object of the present invention to provide an energy absorber for a bumper that can improve the absorption rate due to cross-sectional deformation during a low-speed collision and reduce vehicle damage.

상기 범퍼커버(10)의 내측에 거리를 두고 위치되며 중앙에 비드홈(21)이 범퍼 길이 방향으로 연장되고 차체에 마운팅 고정되는 보강빔(20)과,A reinforcement beam 20 positioned at a distance from the inside of the bumper cover 10 and having a bead groove 21 extending in a bumper length direction in the center thereof and fixed to a vehicle body;

상기 보강빔(20)과 범퍼커버(10) 사이에 개재되어 충격 에너지를 흡수하는 에너지업소버(30)로 구성되는 것에 있어서,In the configuration comprising an energy absorber 30 interposed between the reinforcing beam 20 and the bumper cover 10 to absorb the impact energy,

상기 에너지업소버(30)는 일정폭으로 범퍼커버(10)의 내측 형상과 보강빔(20)의 굴곡면을 따라 보강빔(20)의 비드홈(21)에 끼워지는 조립부(31) 양측으로 요홈부(32)와 지지부(34)를 갖도록 성형하고, 수개의 보강비드(33)들이 수평하게 일체로 형성되는 것에 의해 달성된다.The energy absorber 30 extends to both sides of the assembly part 31 fitted into the bead groove 21 of the reinforcing beam 20 along the inner shape of the bumper cover 10 and the curved surface of the reinforcing beam 20 at a predetermined width. It is achieved by molding to have the groove portion 32 and the support portion 34, and several reinforcing beads 33 are formed horizontally integrally.

따라서, 상기와 같이 성형된 단위 에너지업소버(30)를 보강빔(20)에 범퍼 성능에 따라 원하는 개수와 간격으로 배치할 수가 있는 것이며, 충격 흡수역할을 충분히 발휘할 수 있도록 하는 것이다.Therefore, the unit energy absorber 30 formed as described above can be arranged in the reinforcement beam 20 at a desired number and interval according to the bumper performance, and the shock absorption role can be sufficiently exhibited.

또, 차량 손상을 감소하고, 저속 충돌시 차종에 따른 높이 차이로 슬라이딩 현상이 발생되는 것을 줄일 수 있다.In addition, it is possible to reduce the damage to the vehicle, and to reduce the occurrence of the sliding phenomenon due to the height difference according to the vehicle model at low speed collision.

그리고, 성형성 및 조립성이 향상되고 부품의 중량을 현격하게 줄일 수 있어 연비 개선 효과도 얻을 수 있는 것이다.In addition, the moldability and assembly properties are improved, and the weight of the parts can be significantly reduced, thereby improving fuel efficiency.
