본 고안은 자동차용 충돌에너지흡수프레임구조에 관한 것으로, 특히 자동차가 정면 또는 측면으로 충돌할 때 프레임에 가해지는 충돌에너지의 흡수 성능을 높여 자동차의 안전성을 향상시켜 줄 수 있도록 된 자동차용충돌에너지 흡수프레임구조에 관한 것이다.The present invention relates to a collision energy absorption frame structure for automobiles, in particular, collision energy absorption for automobiles to improve the safety of the vehicle by improving the absorption performance of the impact energy applied to the frame when the vehicle collides to the front or side It relates to a frame structure.
자동차의 프레임은 자동차의 추진력과 브레이크 작용과 조향시의 원심력, 노면으로 부터의 충격력, 차체의 중량등에 의한 수직하중 및 각종 반력등에 의한 변형이나 비틀림, 인장, 압축 및 진동에 대해 국부적 또는 전체적으로 충분히 지탱할 수 있어야 하고, 또 찌그러지거나 파손도 일어나지 않아야 할 뿐만아니라, 자동차가 충돌하게 되는 경우 충격력을 충분히 흡수 할 수 있는 구조로 되어야 한다.The frame of the vehicle is sufficient to support the local propulsion, braking, centrifugal force during steering, impact force from the road surface, vertical load due to the weight of the vehicle body, and deformation, torsion, tension, compression and vibration due to various reaction forces. Not only should it be able to be crushed or damaged, but it must also be structured to absorb shocks in the event of a car crash.
그런데 종래의 자동차용 충돌흡수프레임구조는 제8도에 도시된 바와같이, 프레임(30)의 앞쪽에 설치된 크로스멤버(31)의 양측면에 보조부재(32)가 용접으로 각각 연장부착되고, 이 보조부재(32)의 끝부분과 프레임(30)사이에 측면부재(33)가 사선방향으로 용접연결되며, 또 이 측면부재(33)와 프레임(33)사이에는 연결부재(34)가 용접연결되어 있는 구조가 되어 있어, 자동차가 충돌하게 되는 경우 차체프레임(30)뿐만 아니라 상기 보조부재(32)와 측면부재(33)가 함께 찌그러지게 되어 충격력을 유효하게 흡수할 수가 없었고, 또 상기 크로스멤바(31)와 보조부재(32)및 측면부재(33)가 서로 용접으로 연결되는 한편 연결부재(34)를 별도로 추가 설치되어야 하기 때문에, 교환작업이 어려울 뿐만 아니라 조립작업시 작업공수가 많아진다는 문제점이 있었다.By the way, in the conventional vehicle collision absorbing frame structure, as shown in FIG. 8, the auxiliary members 32 are respectively attached and attached to both sides of the cross member 31 provided in front of the frame 30 by welding. The side member 33 is welded in an oblique direction between the end of the member 32 and the frame 30, and the connecting member 34 is welded between the side member 33 and the frame 33. When the vehicle collides with each other, not only the body frame 30 but also the auxiliary member 32 and the side member 33 are crushed together, so that the impact force cannot be effectively absorbed, and the cross member bar ( 31) and the auxiliary member 32 and the side member 33 are connected to each other by welding while the connecting member 34 must be additionally installed, so that not only the replacement work is difficult but also the workmanship increases during assembly work. there was.
이에 본고안은 상기와 같은 문제점을 해소하기 위해 안출된 것으로, 자동차의 정면 또는 측면 충돌시 충돌에너지를 단계적으로 흡수해서 충격력을 완화시켜 줄 수가 있고, 충돌흡수프레임구조가 파손되는 경우에도 프레임을 쉽게 교환해 줄 수 있도록된 충돌에너지흡수프레임구조를 제공함에 그 목적이 있다.In order to solve the above problems, this paper is designed to absorb the impact energy step by step in the front or side collision of the car to alleviate the impact force, and easily break the frame even when the collision absorbing frame structure is damaged. The purpose is to provide a collision energy absorption frame structure that can be exchanged.
이하 본고안은 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the subject matter will be described in detail with reference to the accompanying drawings.
본고안은 프레임(1)의 앞쪽에 설치된 크로스멤버(2)의 양측면에 보조부재(3)의 한쪽이 보울트A(4)로 고정체결되고, 상기 보조부재(3)의 다른쪽에는 측면지지대 내판(5)과 측면지지대 외판(6)으로 이루어지는 측면부재(7)의 한쪽이 보울트B(8)로 고정체결되며, 상기 측면부재(7)다른 한쪽은 상기 프레임(1)상에 사선방향으로 역시 보울트C(9)로 고정체결되어 있다.In the present proposal, one side of the auxiliary member 3 is fastened to the bolt A 4 on both sides of the cross member 2 installed in front of the frame 1, and the side support inner plate is fixed to the other side of the auxiliary member 3. One side of the side member (7) consisting of the side plate (6) and the side support (6) is fastened to the bolt B (8), and the other side of the side member (7) is also diagonally on the frame (1). It is fixed by bolt C (9).
그리고 상기 보조부재(3)와 측면부재(7)가 연결되는 부위에는 조립시 전,후 좌,우의 조립공차를 보완해 주기위해 이들 부재(3,7)의 길이방향으로 각각 장공(10, 11)이 형성되어 이들 장공(10, 11)을 통해 상기 보울트B(8)가 끼워지도록 하고, 상기 측면부재(7)는 "ㄷ"자형상의 측면지지대내판(5)과 측면지지대외판(6)이 보조부재(3)로 부터 소정의 간격(A)만큼을 두고 서로 마주보도록 포개져 길이 방향을 따라 용접고정되며, 상기측면지지대외판(6)의 앞쪽끝부분에는 충돌에 의해 발생되는 탄성 변경을 점차적으로 흡수하기 위해 크기가 다른 다수개의 타원형구멍(12)이 형성되고, 이 측면지지대외판(6)의 됫쪽부분 즉 프레임(1)에 연결되는 부분은 앞쪽부분보다 점차 폭이 넓어지도록 형성되어 삼각형 모형을 이루도록 되어 있다.The auxiliary member 3 and the side member 7 are connected to each other in the longitudinal direction of the members 3 and 7 in order to compensate for the assembly tolerances of the front and rear left and right sides during assembly. ) Is formed so that the bolt B (8) is fitted through these long holes (10, 11), the side member (7) is the "c" shaped side support inner plate (5) and the side support outer plate (6) It is overlapped with each other with a predetermined distance A from the auxiliary member 3 and welded in the longitudinal direction, and the elastic change caused by the collision is gradually applied to the front end of the side support outer plate 6. A plurality of elliptical holes 12 having different sizes are formed to absorb them, and the right side portion of the side support outer plate 6, that is, the portion connected to the frame 1 is formed to be gradually wider than the front portion to form a triangular model. It is supposed to be.
상기와 같이 구성된 본 고안은, 크로스멤버(2)의 양측면에 고정 설치된 보조부재(3)와 이 보조부재(3)와 프레임(1)을 사선방향으로 연결시켜 주는 측면부재(7)가 각 보울트로 체결시켜 주도록 되어있어서, 자동차가 충돌등으로 인하여 이 부분의 프레임 구조가 파손될 경우, 상기 보조부재(3)와 측면부재(7)를 쉽게 교환할 수 있도록 되어 있다. 또 상기 측면부재(7)는 "ㄷ"자형상의 측면지지대내판(5)과 측면지지대외판(6)이 보조부재(3)로 부터 일정한 간격(A)를 두고 서로 마주 보도록 포개져 길이방향을 따라 용접되어 있어서, 자동차가 충돌할때 발생하게되는 충돌에너지가 제6도 및 제7조에 도시된 바와 같이 측면지지대 내판(5)의 A구간에서 1차적으로 흡수된 다음 측면부재(7)의 B구간에서 2차적으로 흡수되게 됨으로서, 단계적으로 충돌에너지가 흡수되어 충격력을 완화시켜 주게 된다.According to the present invention configured as described above, each bolt has an auxiliary member 3 fixed to both sides of the cross member 2 and a side member 7 connecting the auxiliary member 3 and the frame 1 in an oblique direction. The auxiliary member 3 and the side member 7 can be easily replaced when the frame structure of this part is damaged due to a collision or the like. In addition, the side member 7 is stacked along the longitudinal direction so that the "c" shaped side support inner plate 5 and the side support outer plate 6 face each other at regular intervals A from the auxiliary member 3. As welded, the collision energy generated when the vehicle collides is absorbed primarily in section A of the side support inner plate 5 as shown in FIGS. 6 and 7 and then in section B of the side member 7. By being absorbed secondarily at, the collision energy is absorbed step by step to alleviate the impact force.
또한 상기 측면부재(7)의 측면지지대외판(6) 앞쪽에는 크기가 다른 다수새의 타원형구멍(12)이 소정 간격을 두고 형성되어져 있어서, 충돌에 의해 발생하게 되는 탄성변형을 점차적으로 흡수되도록 되어 있다.In addition, in front of the side support plate 6 of the side member 7 is formed a plurality of elliptical holes 12 of different sizes at predetermined intervals, so as to gradually absorb the elastic deformation caused by the collision. have.
한편, 상기 보조부재(3)와 측면부재(7)가 결합되는 부분의 끝쪽에 길이방향으로 형성된 장공(10, 11)을 통해 이들 부재(3,7)가 보울트B(8)로 고정체결되도록 되어 있어서, 보조부재(3)와 측면부재(7)의 조립시 전,후 좌,우의 조립공차를 보상 주게 되고, 상기 측면부재(7)안쪽은 점진적으로 폭이 넓어지도록 되어 있어서 변형응력에 대한 내구력이 커지게 되어 충돌시 측면부재(7)가 프레임(1)상에서 떨어지는 현상이 방지될 수 있게 된다.Meanwhile, the members 3 and 7 are fixedly fastened to the bolt B 8 through the long holes 10 and 11 formed in the longitudinal direction at the end of the portion where the auxiliary member 3 and the side member 7 are coupled. When the auxiliary member 3 and the side member 7 are assembled, the assembly tolerances of the front and rear left and right sides are compensated for, and the inner side of the side member 7 is gradually widened so that the side member 7 can be gradually expanded. The durability is increased so that the phenomenon that the side member 7 falls on the frame 1 during a collision can be prevented.
이상의 설명에서와 같이, 본고안은 크로스멤버(2)와 보조부재(3) 및 측면부재(7)가 보울트로 조립 체결시켜지게 되고, 측면부재(7)가 "ㄷ"자형 단면을 갖는 측면지지대내판(5)이 측면지지대외판(6)에 길이방향으로 용접결합되며 또 상기 측면부재(7)를 이루는 측면지지대외판(6)의 앞쪽에는 크기가 서로 다른 다수개의 타원형의 구멍(12)이 헝성되어 있기 때문에, 충돌시 충돌에너지흡수프레임구조가 파손되더라도 교환작업이 쉬워지게 되고, 또 상기 충돌에너지를 단계적으로 흡수하게 됨으로서 충격력을 완화시켜 주는 효과가 있는 것이다.As described above, the subject matter of the cross member 2, the auxiliary member 3 and the side member 7 is assembled into a bolt, and the side member 7 has a "c" shaped cross section side support A plurality of elliptical holes 12 having different sizes are formed in the front side of the side support outer plate 6, in which the inner plate 5 is longitudinally welded to the side support outer plate 6 and constituting the side member 7. Therefore, even if the collision energy absorption frame structure is damaged during collision, the replacement operation becomes easy, and the impact energy is alleviated by absorbing the collision energy step by step.
