승합차용 종부재의 충격흡수구조{Impact absorption structure of length frame for van}Impact absorption structure of length frame for van

본 발명은 승합차의 종부재에 관한 것으로서, 더욱 상세히는 승합차가 전방충돌을 하는 경우 그 충격에너지를 종부재의 전방부가 충분히 감쇄시키지 못함에 따라 종부재와 함께 종부재의 전방부 상측에 위치하는 승객실이 크게 변형되면서 승객의 상해가 더욱 가중되는 문제점을 효과적으로 방지토록 한 승합차용 종부재의 충격흡수구조에 관한 것이다.The present invention relates to a longitudinal member of a van, and more particularly, a passenger positioned above the longitudinal part of the longitudinal member together with the longitudinal member as the front part of the longitudinal member is not sufficiently attenuated when the van collides with the front collision. As the seal is greatly deformed, the present invention relates to a shock absorbing structure of a van member for effectively preventing a problem in which passenger injury is further increased.

일반적으로 프레임에는 자동차의 종류, 용도, 구동방식 및 기관이나 현가장치의 설치위치 등에 의하여 보통프레임과 특수프레임과 일체구조형으로 구분할 수 있으며, 상기 보통프레임에는 버스나 트럭에 많이 사용되고 2개의 사이드멤버에 여러개의 크로스맴버를 접합하여 사디리꼴 모양을 하고 있는 간단한 구조의 H형 프레임과, 승용차에 주로 사용되며 굽음이나 비틀림에 견딜 수 있도록 만들어졌고 프레임 전체의 비틀림 강성을 높일 수 있는 구조인 X형 프레임이 있다.In general, the frame can be divided into a general frame and a special frame and integral structure according to the type, use, driving method, and the installation position of the engine or suspension device. H-shaped frame with simple structure by joining several cross members, and X-shaped frame, which is mainly used in passenger cars, is made to withstand bending or torsion and can increase the torsional rigidity of the whole frame. have.

그리고 특수프레임에는 자동차의 무게를 가볍게 하고 차의 중심을 낮추기 위하여 사용되는 프레임으로서 1개의 굵은 강관이나 "ㅁ" 형이나 "I" 형 단면으로 된 등뼈를 가지며 이것에 기관이나 차체를 설치하기 위한 브라켓 등이 고정되어 있는 백본형 프레임과, 프레임과 차체의 바닥을 일체로 만든 것으로서 "H" 형 프레임과 비슷하나 차체와 조합되면 상자형의 단면이 되어 차체와 함께 비틀림이나 굽음에 대해 큰 강성을 나타내는 플랫폼형 프레임과, 스페이스 프레임이라고도 하며 강관을 용접하여 트러스 구조로 형성한 것으로서 중량이 가볍고 강성이 있으므로 높은 성능을 요구하는 자동차에 사용하나 대량 생산에는 적합하지 않은 트러스형 프레임으로 구분할 수 있다.The special frame is used to lighten the weight of the car and to lower the center of the car. It has a thick steel pipe or a spine with a "ㅁ" or "I" cross section and a bracket for installing the engine or the body. The backbone frame with the back fixed and the bottom of the frame and the body are integrally similar to the "H" frame, but when combined with the car body, it becomes a box-shaped cross section that shows great rigidity against torsion and bending along with the body. Also known as platform frame and space frame, it is made of truss structure by welding steel pipe. It is light weight and rigid, so it can be divided into truss frame which is used for automobiles requiring high performance but not suitable for mass production.

또한 일체구조형은 프레임과 차체를 일체로 구조한 것이며 세로맴버나 가로맴버를 두지 않고 차체 전체로 하중이 분담되도록 한 것으로서 차체의 중량을 줄일수 있고 강도를 증가시킬 수 있다.In addition, the integrated structure is a frame and the body is integrally structured so that the load is shared throughout the body without having vertical or horizontal members, so that the weight of the body can be reduced and the strength can be increased.

이에 예시한 바와 같이 본 발명은 승합차용 종부재의 전방부를 보강함에 있어서, 상면이 개방되어 있고 일정한 길이로 구성되며 양쪽 측면에는 플랜지부(211)가 형성되고 저면은 후방으로 연장되어 연결부(212)가 형성된 제1부재(210)와, 상기 제1부재(210)의 내부에 끼워져 결합될 수 있도록 상면은 개방되고 일정한 길이를 가지며 양측면에는 플랜지부(221)가 형성되어 상기 제1부재(210)의 플랜지부 (211) 상부에 겹쳐진 상태로 결합되는 제2부재(220)로 이루어진 다수개의 보강부재 (200)와; 상기 다수개의 보강부재(200) 전면에 가로방향으로 고정되는 받침부재 (300)와; 종부재(100)의 전방에 위치한 가로부재(110)의 양 끝단과 세로부재의 일측을 서로 연결하는 연결부재(400)로 구성된 종부재의 충격흡수구조를 특징으로 하는 것이다.As exemplified in the present invention, in reinforcing the front part of the vertical member for the van, the upper surface is open and has a constant length, and flanges 211 are formed at both sides, and the bottom surface is extended to the rear portion 212. Is formed so that the upper surface is open and has a predetermined length and a flange portion 221 is formed on both sides so that the first member 210 and the first member 210 can be inserted into the first member 210 to be coupled to each other. A plurality of reinforcing members (200) consisting of a second member (220) coupled in an overlapping state on the flange portion (211) of the upper portion; A supporting member 300 fixed to the front of the plurality of reinforcing members 200 in a horizontal direction; Characterized in that the shock absorbing structure of the vertical member consisting of a connecting member 400 for connecting both ends of the horizontal member 110 and one side of the vertical member located in front of the vertical member 100.

이러한 본 발명은 승합차의 종부재 전방에 충격을 분산 및 흡수할 수 있는 수단을 설치하므로서, 승합차의 전방충돌시 전방으로부터 가해지는 충격에너지가 상기 수단에 의해 충분히 완화되면서 차체의 전면부와 범퍼가 승객실로 밀리는 현상을 최대한 방지토록 한 것이다.The present invention provides a means for dispersing and absorbing the shock in front of the longitudinal member of the van, so that the impact energy applied from the front during the front collision of the van is sufficiently alleviated by the means, so that the front part and the bumper of the vehicle body are passengers. It is to prevent the phenomenon to push as much as possible.

한편, 도 3 은 본 발명에 따라 종부재의 전방에 설치되어 종부재의 전방으로 부터 가해지는 충격을 완화시킬 수 있도록 한 수단을 예시한 것으로서, 상기 수단은 다수개의 보강부재(200)와, 받침부재(300)와, 한쌍의 연결부재(400)로 이루어져 있다.On the other hand, Figure 3 illustrates a means to mitigate the impact applied from the front of the longitudinal member is installed in front of the longitudinal member in accordance with the present invention, the means is a plurality of reinforcing members 200 and the support It consists of a member 300 and a pair of connection member 400.

즉, 도 4 에 예시한 바와 같이 상기 보강부재(200)는 제1부재(210)와 제2부재(220)로 이루어져 있는데, 제1부재(210)는 "┗┛" 단면형상을 가지면서 일정한 길이로 구성되고, 양측면의 상부는 바깥쪽으로 구부러져 플랜지부(211)를 이루고 있으며, 저면은 후방으로 연장되어 연결부(212)를 이루고 있다.That is, as shown in Figure 4, the reinforcing member 200 is composed of a first member 210 and the second member 220, the first member 210 has a constant "┗┛" cross-sectional shape It is composed of a length, the upper side of both sides is bent outward to form a flange portion 211, the bottom surface is extended to form a connection portion 212.

그리고 제2부재(220)는 상기 제1부재(210)의 내부에 겹쳐질 수 있도록 제1부재(210) 보다는 작은 크기의 "┗┛" 단면형상을 가지면서 역시 일정한 길이로 구성되고, 양측면 상부 또한 제1부재(210)와 같은 플랜지부(221)가 형성되어 있다.In addition, the second member 220 has a "┗┛" cross-sectional shape of a smaller size than the first member 210 so that the second member 220 may overlap the inside of the first member 210, and is also configured to have a constant length. In addition, the same flange portion 221 as the first member 210 is formed.

따라서 제1부재(210)의 상부로 제2부재(220)를 올려놓게 되면 제2부재(220)의 플랜지부(221)가 제1부재(210)의 플랜지부(211)에 겹쳐지게 되며 이러한 상태에서 제1부재(210)의 플랜지부(211)와 제2부재(220)의 플랜지부(221)를 서로 용접하여 고정시켜 하나의 보강부재(200)를 형성하게 되는 것이며, 이러한 보강부재(200)를 다수개 구성한 것이다.Accordingly, when the second member 220 is placed on the upper portion of the first member 210, the flange portion 221 of the second member 220 overlaps the flange portion 211 of the first member 210. In this state, the flange portion 211 of the first member 210 and the flange portion 221 of the second member 220 are welded to each other to form one reinforcement member 200, and such a reinforcement member ( It is composed of a plurality of 200).

그리고 상기 다수개의 보강부재(200)를 종부재(100)의 가로부재(110) 전면에 위치시킨 상태에서 보강부재(200)의 제1부재(210)에 형성된 연결부(212)를 상기 가로부재(110)의 저면에 위치시켜 용접으로 고정시키므로서 다수개의 보강부재(200)후단이 일정한 간격이 유지하면서 종부재(100)의 가로부재(110)에 수직방향으로 고정되는 것이다.And the horizontal member (110) formed on the first member 210 of the reinforcing member 200 in a state in which the plurality of reinforcing members 200 are located in front of the horizontal member 110 of the longitudinal member 100 The rear end of the plurality of reinforcing members 200 is fixed in the vertical direction to the horizontal member 110 of the longitudinal member 100 while maintaining a predetermined interval by fixing the position by fixing on the bottom of the 110.

또한 상기 각각의 종부재(100) 전단에는 가로방향으로 구성된 받침부재(300)가 함께 연결되도록 한 것이며, 상기 받침부재(300)는 범퍼의 내부에 위치하게 되는 것이다.In addition, the front end of each longitudinal member 100 is to be connected to the supporting member 300 configured in the horizontal direction, the supporting member 300 is to be located inside the bumper.

그리고 상기 가로부재(110)의 양쪽 끝단부위의 경우 보강부재(200)가 위치하게 되면서 전방충돌시 보강부재(200)에 의해 밀림이 발생하게 되므로 가로부재 (110)의 양쪽 끝단과 세로부재(120)의 일측을 연결부재(400)로 연결하므로서 가로부재(110)에 가해지는 충격에너지가 효과적으로 분산 및 흡수될 수 있도록 한 것이다.In the case of both ends of the horizontal member 110, since the reinforcement member 200 is positioned and the frontal collision occurs by the reinforcement member 200, both ends and the vertical member 120 of the horizontal member 110 are generated. By connecting one side of the) to the connecting member 400, the impact energy applied to the horizontal member 110 is to be effectively dispersed and absorbed.

따라서 승합차가 전방충돌을 하면서 범퍼에 충격에너지가 가해지게 되면 받침부재(300)와 보강부재(200)와 연결부재(400)가 변형되면서 상기 충격에너지를 충분히 감쇄시킴에 따라 종부재(100)의 변형이 최대한 억제되면서 승객실의 변형을 최소화시킬 수 있는 것이다.Therefore, when impact energy is applied to the bumper while the van collides with the front collision, the supporting member 300, the reinforcing member 200, and the connecting member 400 are deformed, thereby sufficiently reducing the impact energy of the vertical member 100. It is possible to minimize the deformation of the passenger compartment while suppressing the deformation as much as possible.

이상에서 상술한 바와 같이 본 발명은 승합차의 종부재 전방부에 설치된 받침부재와 보강부재와 연결부재로 인하여 승합차의 전방충돌에 의해 발생되는 충격에너지가 흡수 및 분산될 수 있어 종부재의 변형에 따른 승객실의 변형을 최소화시켜 승합차의 전방충돌에 의한 승객의 상해를 최대한 저감시킬 수 있는 것이다.As described above, the present invention can absorb and disperse the impact energy generated by the front collision of the van due to the support member, the reinforcing member and the connecting member installed in the front of the longitudinal member of the van, and according to the deformation of the longitudinal member. By minimizing the deformation of the passenger compartment, passenger injuries due to the front collision of the van can be minimized.
