And a side member 20 which is integrally formed in the body and formed into a quadrangular hollow in the cross section, and into which the bumper stay 11 is inserted, wherein the bumper stay 11 has an upper surface and The slot 12 is formed on the side surface to guide the guide pin 21 fixed to the side member 20 to allow the bumper stay 11 to slide backward in the event of a collision. The second operating chambers 22, 22 'are formed above and below the tip position of the bumper stay 11 in the state before the bumper collision energy is applied, and the first springs 23, 23' are built in the side members ( 20 is supported by the springs 23 and 23 ' The triangular cushioning members 24 and 24 'are hinged to protrude, thereby restraining the tip of the bumper stay 11 during non-collision, and behind the buffering members 24 and 24' of the side member 20. A second spring having the stopper plate 25 fixed thereto so as to form a first operating chamber 26 between the stopper plate 25 and the shock absorbing members 24 and 24 'to install the support plate 28 at the front end. It was built with (27).

상기한 범퍼 장착구조는 비충돌시에는 범퍼 스테이(11)는 도 5와 같이 그 선단이 완충부재(24)(24')에 구속되어 있는 상태를 유지하고 있다가 범퍼에 탄성한계 이내의 충돌 에너지가 가하여 지면 기존의 백 빔(10) 또는 에너지 압소버(미도시)와 백 빔(10)이 탄성변형하여 충돌 에너지를 흡수하고, 상기 백 빔(10) 등에 탄성한계 이상의 충돌 에너지가 가하여지면 범퍼 스테이(11)는 그 슬롯(12)이 가이드 핀(21)을 따라 후방으로 가이드 되면서 범퍼 스테이(11)가 사이드 멤버(20)에 더욱 더 삽입되고 그 선단이 완충부재(24)(24')를 제 2 작동실(22)(22') 측으로 수납시킬 때 제 1 스프링(23)(23')이 압축되면서 탄성에 의하여 1차로 충돌 에너지를 흡수하고, 계속하여 범퍼 스테이(11)의 선단이 후방으로 밀림에 따라 제 1 작동실(26)에 내장된 제 2 스프링(27)이 압축되면서 그 탄성에 의하여 2차로 충돌 에너지를 흡수하도록 한 것이다.In the bumper mounting structure, when the bumper is not collided, the bumper stay 11 maintains a state in which the tip thereof is constrained to the buffer members 24 and 24 'as shown in FIG. When the existing back beam 10 or the energy absorber (not shown) and the back beam 10 are elastically deformed, the impact energy is absorbed, and when the impact energy of the back beam 10 or the like is applied to the back beam 10 or more, the bumper is applied. The stay 11 has a slot 12 guided rearward along the guide pin 21, and the bumper stay 11 is further inserted into the side member 20, and the front end thereof is a buffer member 24, 24 '. The first springs 23 and 23 'are compressed to absorb collision energy primarily by elasticity, and the front end of the bumper stay 11 As it is pushed backward, the second spring 27 built into the first operating chamber 26 is compressed, 2 is a drive which will absorb the impact energy by.

그러나 상기한 범퍼 장착구조는 범퍼에 큰 충돌 에너지가 가하여 지면 범퍼 스테이(11)가 사이드 멤버(20) 측으로 슬롯(12)의 길이만큼 삽입됨으로써 범퍼의 밀림량이 크기 때문에 후드 패널, 헤드 램프 등의 손상이 심하고, 또한 기존의 백 빔(10) 또는 에너지 압소버 및 백 빔(10)의 충돌 에너지 흡수기능을 이용하지 못하고 강체기능을 하게 되는 것이다.However, in the above bumper mounting structure, the bumper stay 11 is inserted by the length of the slot 12 toward the side member 20 by applying a large collision energy to the bumper, thereby causing damage to the hood panel and the head lamp. This severe and also does not use the collision energy absorption function of the existing back beam 10 or the energy absorber and the back beam 10 to function as a rigid body.

상기와 같이 백 빔(10) 등이 강체기능을 하고 사이드 멤버(20)의 강성이 크기 때문에 30 마일/h (48㎞/h)이상의 고속 충돌시 충돌 에너지의 흡수가 양호하지 못한 문제점이 있는 것이다.As described above, since the back beam 10 and the like function as a rigid body and the rigidity of the side member 20 is large, there is a problem in that the collision energy absorption is not good at high speeds of 30 miles / h (48 km / h) or more. .

A plurality of holes 53 and 54 formed in the side plate 20 and the bumper stay 11 at the right angle with the absorbing plate 51 and having the same cross-section as the absorbing plate 51. And the absorber plate 51 is inserted into the holes 53 and 54 so that the engaging plate 52 is supported on the upper surface of the side member 20, respectively. 11) is combined.

상기와 같이 사이드 멤버(20)에 범퍼 스테이(11)를 결합할 때 플랜지(110)와 사이드 멤버(20)의 전방 사이에는 일정간극의 밀림부(d)를 형성하며, 또한 상기 에너지 흡수부재(50)의 개수는 자동차의 중량 등에 따라 증감 조정할 수 있는 것이다.When the bumper stay 11 is coupled to the side member 20 as described above, a gap d of a predetermined gap is formed between the flange 110 and the front of the side member 20, and the energy absorbing member ( The number of 50) can be increased or decreased adjusted according to the weight of the vehicle.

미설명부호 21은 세팅편으로써, 사이드 멤버(20)에 범퍼 스테이(11)를 결합할 때 구멍(53)(54)을 일치시키는 기능을 하는 것이다.Reference numeral 21 is a setting piece, which serves to match the holes 53 and 54 when the bumper stay 11 is coupled to the side member 20.

이상과 같은 본 발명은 범퍼에 충돌 에너지가 가하여 지면 범퍼 스테이(11)는 사이드 멤버(20)에 에너지 흡수부재(50)로써 결합되어 있음으로 충돌 에너지가 작을 경우에는 백 빔(10) 또는 백 빔(10)과 에너지 압소버와, 에너지 압소버(40)의 에너지 흡수부(41)와, 에너지 흡수부(41)가 더욱 더 변형하면서 범퍼 스테이(11)의 전방에 형성한 플랜지(110)에 지지되면서 순서대로 3차에 걸쳐 충돌 에너지를 흡수하기 때문에 충돌 에너지 흡수가 양호하고, 범퍼의 밀림량이 최소화되어서 후드 패널, 헤드 램프 등의 손상이 없게 되는 것이다.According to the present invention as described above, when the collision energy is applied to the bumper and the ground bumper stay 11 is coupled to the side member 20 as the energy absorbing member 50, when the collision energy is small, the back beam 10 or the back beam is small. 10, the energy absorber, the energy absorbing portion 41 of the energy absorber 40, and the energy absorbing portion 41 are further deformed to the flange 110 formed in front of the bumper stay 11. Since the collision energy is absorbed three times in order while being supported, the collision energy absorption is good, and the amount of bumping of the bumper is minimized, thereby preventing damage to the hood panel and the head lamp.

그리고 범퍼에 가하여 지는 충돌 에너지가 클 경우에는 상기 충돌 에너지가 작을 때와 같이 충돌 에너지를 흡수함과 동시에 고강성 재질로 된 에너지 흡수부재(50)에서 사이드 멤버(20) 및 범퍼 스테이(11)에 형성한 구멍(52)(53)이 변형되면서 다시 충돌 에너지를 흡수함으로써 충돌 에너지 흡수가 양호하며, 이때 플랜지(110)와 사이드 멤버(20)의 전방은 밀림부(d)를 형성하였음으로 충돌 에너지의 흡수에 지장이 없게 되는 것이다.When the collision energy applied to the bumper is large, the collision energy is absorbed as in the case where the collision energy is small, and at the same time, the energy absorbing member 50 made of a high rigid material is applied to the side member 20 and the bumper stay 11. As the formed holes 52 and 53 are deformed, collision energy absorption is good by absorbing collision energy again, and at this time, the front of the flange 110 and the side member 20 has a collision portion d, thereby forming collision energy. It will not interfere with the absorption of.

상기와 같이 충돌 에너지가 클 경우 사이드 멤버(20) 및 범퍼 스테이(11)에 형성한 구멍(52)(53)이 변형할 경우에도 이들을 냉간압연 또는 열간압연 강판 등으로 제조되는 것임을 그 수리가 간편한 것이다.When the collision energy is large as described above, even if the holes 52 and 53 formed in the side member 20 and the bumper stay 11 are deformed, they are made of cold rolled steel or hot rolled steel sheet. will be.

이상과 같이 본 발명은 백 빔과 범퍼 스테이 사이에 에너지 압소버를 배치하고, 사이드 멤버에 범퍼 스테이를 에너지 흡수부재로 결합하여 수회에 걸쳐 충돌 에너지를 흡수하였기 때문에 충돌 에너지의 흡수가 양호할 뿐 아니라 범퍼의 밀림량이 최소화되어서 후드 패널, 헤드 램프 등의 손상이 작게 되는 것이다.As described above, in the present invention, since the energy absorber is disposed between the back beam and the bumper stay, and the bumper stay is coupled to the side member as the energy absorbing member, the collision energy is absorbed several times, so that the absorption of the collision energy is not only good. Since the bump amount of the bumper is minimized, damage to the hood panel and the head lamp is reduced.
