Description
본 고안은 자동차 측면 하부의 차체구조에 관한 것으로서, 특히 승원의 안전성을 향상시켜 차량의 측부 충돌시, 차체가 변형되는 것에의해 차량의 측면부가 차실내로 침입되는 것을 효과적으로 억제하도록 하는 자동차 측면충돌 보강구조에 관한 것이다.The present invention relates to a vehicle structure of the lower side of the vehicle, particularly to enhance the safety of the occupants to reinforce the side collision of the vehicle to effectively suppress the intrusion of the side portion of the vehicle by the deformation of the vehicle body during the side collision of the vehicle It's about structure.
일반적으로 자동차의 차체구조는 제1도에 도시하고 있는 바와 같이 전면기둥(1:front pillar)과 중간기둥(2:center pillar) 및 후면기둥(3 : rear pillar) 사이에 개구부가 형성되어, 상기 개구부에 도어(4)가 개폐 가능하게 설치되고, 상기 기둥(1)(2)(3)들 상단부에 지붕의 외측부를 형성하는 루프레일(5 : roof rail)이 연결되며, 상기 기둥(1)(2)(3)들 하단부에 자동차의 하부를 형성하는 플로어판넬의 일측단부가 사이드실(20)의 일측면에 취부되어 있다.In general, as shown in FIG. 1, an automobile body structure has an opening formed between a front pillar, a center pillar, and a rear pillar. A door 4 is installed to be opened and closed at an opening, and a roof rail 5 which forms an outer portion of the roof is connected to an upper end of the pillars 1, 2, 3, and the pillar 1. One end of the floor panel forming the lower part of the vehicle is attached to one side of the side chamber 20 at the lower end of the (2) (3).
여기에서, 종래 자동차의 하부구조는, 제2도에 도시하고 있는 바와 같이, 플로어판넬(10 : Floor PANNEL)의 좌우 양측에 리어사이드프레임(30)이 취부되고, 상기 리어사이드프레임(30)의 일측면에는 사이드실(20)을 형성하는 내측판넬(21)이 용착되어 있다.Here, in the conventional vehicle undercarriage, as shown in FIG. 2, the rear side frame 30 is mounted on both left and right sides of the floor panel 10, and the rear side frame 30 of the rear side frame 30 is mounted. On one side, the inner panel 21 which forms the side chamber 20 is welded.
이와같이 구성되는 종래 자동차 하부구조는, 도어의 하단부가 사이드실(20)의 상단부에 일정폭 수납되도록 되어, 측면충돌시 상기 사이드실(20)에 의해 1차적으로 충격에너지를 흡수하고, 2차적으로 사이드실(20)의 내측판넬(21)에 용착된 리어사이드프레임(30)에서 충격하중을 흡수하며, 3차적으로 플로어판넬(10)로 분산시켜 측부 구조물인 도어가 실내로 침입되는 것을 억제하여, 측부 차체의 변형을 억제하고 실내의 승원이 보호되도록 되어 있다.In the conventional vehicle undercarriage structure configured as described above, the lower end of the door is accommodated in the upper end of the side chamber 20 by a predetermined width, so that the impact energy is primarily absorbed by the side chamber 20 when the side collision occurs, and the secondary The shock absorbing load is absorbed by the rear side frame 30 welded to the inner panel 21 of the side seal 20, and is distributed to the floor panel 10 in a third manner to prevent the door, which is a side structure, from entering the room. In addition, the deformation of the side vehicle body is suppressed and the occupants of the room are protected.
그러나, 이러한 종래 자동차 측면하부 차체구조는 측면 충돌시, 충돌하는 차량의 범퍼 하부쪽에 사이드실(20)과 플로어판넬(10)이 위치되어 비교적 큰 하중이 집중되기 때문에 사이드실(20)의 내측판넬 (21)에 일측면이 용접에 의해 결합되어 있는 리어사이드프레임(30)이 차량의 측면으로 충격이 가해지는 경우, 충돌에 의해 발생한 충돌에너지를 효과적으로 분산시키지 못하게 됨으로서, 차체하부의 변형이 크게 발생하여 도어와 함께 측면부 차체가 실내로 침입하게 됨으로서, 차실에 탑승한 승원의 안전이 위협을 받게되는 문제점이 있었다.However, in the conventional vehicle side lower body structure, the side chamber 20 and the floor panel 10 are located at the lower side of the bumper of the colliding vehicle during side collision, so that a relatively large load is concentrated, the inner panel of the side chamber 20 When the rear side frame 30, the one side of which is coupled to the side 21 by welding, is applied to the side of the vehicle, the impact energy caused by the collision cannot be effectively dispersed, thereby greatly causing deformation of the underbody. Therefore, the side of the body along with the door intruded into the room, there was a problem that the safety of the occupant in the cabin is threatened.
본 고안의 목적은 상기와 같은 종래의 문제점을 보완하기 위해, 사이드실의 내측판넬 하단부에 걸림턱을 형성하고, 상기 걸림턱에 리어사이드프레임의 하단부를 취부하며, 상기 리어사이드프레임의 타측부는 경사부를 갖도록 플로어판넬의 저면에 취부하여, 차량의 측면으로 충격이 가해지는 경우 발생하는 충격에너지의 충격하중을 측면부 차체에 폭넓게 분산되도록 하는 동시에, 차체의 변형량을 억제 하도록 하는 자동차 측면충돌 보강구조를 제공하는 데 있다.An object of the present invention is to form a locking step in the lower end of the inner panel of the side seal, in order to supplement the conventional problems as described above, attaching the lower end of the rear side frame to the locking step, the other side of the rear side frame An automobile side collision reinforcement structure is mounted on the bottom of the floor panel so as to have an inclined portion so that the impact load of the impact energy generated when an impact is applied to the side of the vehicle can be widely distributed on the side body, and the amount of deformation of the body is suppressed. To provide.

이하 첨부된 도면에 의하여 본 고안의 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration of the present invention with reference to the accompanying drawings in detail.
본 고안의 자동차 측면충돌 보강구조도 제3도에 도시되는 바와 같이, 플로어판넬(10 : FLOOR PANNEL)의 좌우 양측에 리어사이드프레임(30)이 취부되고, 상기 리어사이드프레임(30)의 일측면에는 사이드실(20)을 형성하는 내측판넬(21)이 용착되는 기술적 사상은 종래와 같다. 단 본 고안은 상기 사이드실(30)의 내측판넬(21) 하단부에 걸림턱 (22)이 형성되고, 상기 걸림턱(22)에 리어사이드프레임(30)의 하단부가 취부되며, 상기 리어사이드프레임(30)의 타측부는 경사부를 갖으며 플로어판넬(10)의 저면에 취부됨을 그 기술적 구성상의 기본 특징으로 한다.As shown in FIG. 3, the rear side frame 30 is mounted on the left and right sides of the floor panel 10, and one side surface of the rear side frame 30 is shown. The technical idea that the inner panel 21 to form the side seal 20 is welded as in the prior art. However, in the present invention, the locking jaw 22 is formed at the lower end of the inner panel 21 of the side seal 30, and the lower side of the rear side frame 30 is mounted at the locking jaw 22, and the rear side frame The other side of the 30 has an inclined portion and is mounted on the bottom of the floor panel 10 as a basic feature of the technical configuration.
이와같이 구성되는 본 고안은 측면 충돌시 플로어판넬(10)의 측단부가 취부되어 있는 사이드실(40)의 폐단면에 의해 1차적으로 충격에너지가 흡수되어 충격하중이 분산되고, 2차적으로 사이드실(20)과 플로어판넬(10)을 연결하며 내부에 폐단면이 형성된 리어사이드프레임 (30)에서 실내쪽으로 작용하는 충격하중을 흡수하고, 차체의 횡방향으로 폭넓게 하중을 분산시켜, 실내로 전달되는 충격을 완충시켜 주고, 중간기둥 및 측부 차체가 실내로 침입되는 것을 효과적으로 억제시켜 준다.According to the present invention configured as described above, the impact energy is primarily absorbed by the closed end surface of the side chamber 40 in which the side end portion of the floor panel 10 is mounted during side impact, and the impact load is dispersed. (20) and the floor panel (10) to absorb the impact load acting toward the interior from the rear side frame 30, the closed cross-section is formed inside, to distribute the load in the transverse direction of the vehicle body wide, which is transmitted to the room It cushions the impact and effectively suppresses the intrusion into the room.
따라서, 이러한 본 고안은 차량을 운행중 충돌사고가 발생하여 차량의 측면으로 충격이 가해지는 경우에도 차체의 변형이 억제되고, 충격이 효과적으로 완충되어, 측면 충돌시 승원의 안전성이 향상되도록 하는 효과가 잇다.Therefore, the present invention has the effect of suppressing the deformation of the vehicle body even when a collision accident occurs while driving the vehicle, and the impact of the vehicle body is suppressed, the shock is effectively buffered, and the safety of the occupant is improved during the side collision. .
이상에 살펴본 바와 같이 본 고안은 플로어판넬에 설치되는 리어사이드프레임의 저면이 사이드실의 내측판넬에 형성된 걸림턱에 접하며 취부되어, 차량의 측면으로 충격이 가해지는 경우 발생하는 충격에너지의 충격하중을 측면부 차체에 폭넓게 분산되도록 하는 동시에 차체의 변형량을 억제 하도록 하는 매우 유용한 고안인 것이다.As described above, the present invention is installed by contacting the bottom surface of the rear side frame installed on the floor panel in contact with the locking jaw formed on the inner panel of the side chamber, so that the impact load of the impact energy generated when the impact is applied to the side of the vehicle. It is a very useful design to be widely distributed in the side of the vehicle body and to suppress the amount of deformation of the vehicle body.
