본 발명은 범퍼 스테이 정면충돌 완충장치에 관한 것으로서, 더욱 상세하게는 자동차용 범퍼를 차체에 장착하기 위해 범퍼와 차체를 연결 고정하는 범퍼 스테이의 저속 충돌 시 그 충돌 충격량을 흡수하여 차체에 손상이 가는 것을 방지할 수 있는 범퍼 스테이 정면충돌 완충장치에 관한 것이다.The present invention relates to a bumper stay frontal collision shock absorber, and more particularly, to absorb the impact shock during low-speed collision of the bumper stay connecting the bumper and the vehicle body for mounting the bumper for the vehicle to damage the vehicle body The present invention relates to a bumper stay frontal collision buffer device that can prevent the damage.

일반적으로, 자동차의 전/후방에는 범퍼가 설치되어 차체를 보호하기 위해 마련되는 구조물로서 차량의 충돌 시 그 충격을 흡수하는 역할을 한다.In general, a bumper is installed at the front and rear of the vehicle to protect the vehicle body, and serves to absorb the impact when the vehicle collides.

이러한 범퍼를 차체에 고정시키기 위해서는 도 1에서 보듯이, 차체의 프레임을 이루는 사이드 맴버(10)가 양측에 마련되고, 이 사이드 맴버(10) 전방 부분으로 범퍼 백 빔(20)이 마련되며, 이 범퍼 백 빔(20) 후방 양측에는 범퍼 백 빔(20)과 사이드 맴버(10)를 지지할 수 있도록 구성된 범퍼 스테이(30)가 설치되고, 이 범퍼 스테이(30) 후방에는 상기 사이드 맴버(10)에 범퍼 백 빔(20) 후방 양측에 마련된 범퍼 스테이(30)를 사이드 맴버(10)에 결합하기 위해 프레이트(40)가 구비된다.In order to fix the bumper to the vehicle body, as shown in FIG. 1, side members 10 forming the frame of the vehicle body are provided at both sides, and the bumper back beam 20 is provided at the front side of the side member 10. Bumper stays 30 configured to support the bumper back beams 20 and the side members 10 are installed at both rear sides of the bumper back beams 20, and the side members 10 are located behind the bumper stays 30. The plate 40 is provided to couple the bumper stays 30 provided on both sides of the bumper back beam 20 to the side members 10.

상기 범퍼 스테이(30)는 범퍼 백 빔(20)에 용접되어 체결되고, 상기 범퍼 스테이(30)의 형상은 포밍부(31) 형상으로 구성되어, 도 2에서 보듯이, 차량이 전방 저속 충돌 시 범퍼 백 빔(20)은 범퍼 스테이(30)로 그 충돌 하중이 전달되어 사이드 맴버 부재로 하중이 전달된다.The bumper stay 30 is welded and fastened to the bumper back beam 20, and the bumper stay 30 has a shape of a forming part 31, and as shown in FIG. The bumper back beam 20 transmits the collision load to the bumper stay 30 and transmits the load to the side member member.

이렇게, 충돌로 인하여 차체로 전달되는 변형량을 감소시키기 위해 도 2에서 보듯이, 기존에는 상기 범퍼 스테이(30)에 전달되는 충돌 에너지를 포밍부(31) 형상을 주어 범퍼 스테이(30)만 좌굴 될 수 있도록 그 형상을 구성하였다.As such, in order to reduce the amount of deformation transmitted to the vehicle body due to the collision, as shown in FIG. 2, only the bumper stay 30 may be buckled by giving the forming energy 31 to the collision energy transmitted to the bumper stay 30. The shape was configured to be.

그러나, 이러한 종래의 구조는 기존의 사각박스 구조로 단순 포밍 구조의 문제점인 충돌 시 범퍼 스테이 파손시 양 끝단 용접에 의해 해체 작업이 어려운 부분과 용접부위를 제거한 후 재용접하는 작업의 어려움이 있었다.However, such a conventional structure has a difficulty in re-welding after removing a difficult part and a welding part which are difficult to dismantle by welding at both ends when the bumper stay breaks, which is a problem of a simple forming structure.

또한, 차량의 저속 충돌 시 충격량이 사이드 맴버에 직접 전달 되기 전 좌출이 발생되지만 좌굴이 발생된 상태에서 충돌에너지가 존재하게 된다면 사이드 맴버에 그 충돌량이 전달되어 차체부분에 손상을 가함은 물론 승객의 안전성을 위협할 수 있는 문제점을 가지고 있다.In addition, when a low-speed collision of the vehicle causes a left-over movement before the impact amount is directly transmitted to the side member, but if collision energy is present in the state where the buckling occurs, the collision amount is transmitted to the side member and damages the body part of the passenger. It has a problem that can threaten safety.

본 발명은 상기와 같은 문제점을 해결하기 위해 제안된 것으로서, 범퍼 스테이의 구조를 개선하여 차량의 저속 충돌이 발생 되더라도 사이드 맴버에 전달되는 충격 에너지를 그 전에 감소시켜 사이드 맴버에 전달되는 충돌 에너지는 소멸 된 상태가 되어 차체 변형을 방지함과 더불어 승객의 안정성을 향상시킬 수 있는 범퍼 스테이 정면충돌 완충장치를 마련하는데 그 목적이 있다.The present invention has been proposed to solve the above problems, and improves the structure of the bumper stay to reduce the impact energy transmitted to the side members before the impact energy is transmitted to the side members even if a low-speed collision of the vehicle occurs, the collision energy transmitted to the side members disappears The purpose of the present invention is to provide a bumper stay frontal collision shock absorber which can prevent deformation of the vehicle body and improve passenger stability.

이하에서, 상기 서술한 본 발명의 범퍼 스테이 충돌 완충 장치의 작용을 설명한다.The operation of the bumper stay collision shock absorber of the present invention described above will be described below.

차량 주행중 충돌이 일어나면 범퍼에 충격이 가해지면서 이 범퍼를 지지하는 범퍼 백 빔(20)이 그 충격을 받게 되고 이 범퍼 백 빔(20)을 지지하는 범퍼 스테이 하우징(300)로 충격이 전가되면 도 5에서 보듯이, 사각의 형상을 이루는 범퍼 스테이 하우징(300) 외면에 형성된 포밍부(310)가 변형이 발생되어 좌굴 양상으로 진행될 때 범퍼 스테이 하우징(300)의 내부 양측에 설치된 스프링(400)의 탄성력으로 충격량을 1차적으로 흡수하게 된다.If a collision occurs while driving the vehicle, the bumper is impacted and the bumper back beam 20 supporting the bumper is subjected to the shock and the shock is transmitted to the bumper stay housing 300 supporting the bumper back beam 20. As shown in FIG. 5, when the forming part 310 formed on the outer surface of the bumper stay housing 300 having a square shape is deformed and proceeds to the buckling pattern, the springs 400 installed on both sides of the bumper stay housing 300 are disposed. The elastic force absorbs the impact amount primarily.

이렇게, 좌굴이 완전히 완료된 상태에서 충돌 에너지가 존재하더라도 범퍼 스테이 하우징(300)의 중앙부에 위치된 사각형상의 러버가 그 잔류 충격량을 2차적으로 흡수할 수 있게 되어 최종적으로 사이드 맴버(10)에 전달되는 충돌 에너지는 완전히 소멸 된 상태가 되어 차체 변형을 방지하게 된다.In this way, even when collision energy is present in the state where the buckling is completed, the rectangular rubber located at the center of the bumper stay housing 300 can absorb the residual impact amount secondarily and finally transferred to the side member 10. Collision energy is completely dissipated, preventing body deformation.

또한, 차량의 충돌로 인한 파손된 범퍼 스테이 하우징(300)의 부재는 제1,2,3볼트홀(610,710,810)을 체결하고 있는 볼트(900)를 해제한 후 파손된 부재만 교체하면 된다.In addition, the member of the damaged bumper stay housing 300 due to the collision of the vehicle only need to replace the damaged member after releasing the bolts 900 that fasten the first, second, third bolt holes (610, 710, 810).

상술한 바와 같이 본 발명에 따른 범퍼 스테이 정면충돌 완충장치에 따르면, 차량의 저속 충돌이 일어나 사각 박스 내 형성된 포밍부가 변형이 발생되어 좌굴 양상으로 진행될 때 양측에 마련된 스프링에 의한 탄성력으로 그 충격량을 1차적으로 흡수하게 되고, 좌굴이 완전히 형성된 상태에서 충돌 에너지가 존재하더라도 중앙부에 마련된 러버가 충격을 흡수하게 되어 최종적으로 사이드 맴버에 전달되는 충돌 에너지는 소멸 된 상태가 되어 차체 변형을 방지하는 효과는 물론 승객의 안전성 또한 향상시킬 수 있는 효과가 있다.As described above, according to the bumper stay frontal collision buffer according to the present invention, when the low speed collision of the vehicle occurs, the forming part formed in the rectangular box is deformed, and when the deformation proceeds to the buckling mode, the impact amount is determined by the elastic force of the springs provided at both sides. Absorption is carried out automatically, and even if there is collision energy in the state that the buckling is completely formed, the rubber provided in the center absorbs the shock and finally the collision energy delivered to the side member is extinguished to prevent the body deformation. The safety of the passengers can also be improved.

또한, 충돌 후 파손된 범퍼 스테이는 간단하게 볼트를 제거한 후 파손된 부재만 교체하면 되므로 수리비의 저감 효과를 가져 올 수 있다.In addition, since the bumper stay broken after the collision simply removes the bolts and replaces only the broken member, the bumper stay may reduce the repair cost.
