Description
일반적으로 승용자동차는 도 1에 도시되는 바와 같이, 차체(10)의 양측면부에 전면기둥(front pillar)(30)과 중심기둥(center pillar) 및 후면기둥(rear pillar)이 상부로 연장되고, 상기 기둥들 사이에 각기 도어가 설치되도록 하는 개구부가 형성되어, 전면기둥(30)과 중심기둥 및 후면기둥들의 상단부에 루프판넬(20)의 외곽부를 형성하는 사이드아웃프레임(side out frame)이 연결되고, 상기 기둥들 및 측면부 하단부가 차량의 저면부를 형성하는 플로어판넬(floor panel) 및 양측단부의 사이드실(side sill)에 연결되어 있다.In general, as shown in FIG. 1, a front pillar 30, a center pillar, and a rear pillar extend upwards on both side surfaces of the vehicle body 10. Openings are formed between the pillars to allow doors to be installed, and a side out frame connecting the front pillar 30 and the center pillar and the rear pillars to form an outer portion of the roof panel 20 is connected to the side out frame. The pillars and the lower end of the side portion are connected to a floor panel forming a bottom portion of the vehicle and side sills at both ends.
여기에서, 종래 전면기둥(30)은 도 2에 도시되는 바와 같이, 임의의 형상으로 절곡된 내측판넬(inner panel)(31)과 외측판넬(outer panel)이 소정의 공간을 두고 폐단면으로 결합되어, 외측판넬의 상단부가 루프판넬(20)의 외곽 측부인 사이드아웃프레임(22)에 연결되도, 내측판넬(31)이 루프판넬(20)의 선단부 내측에 부착되는 프론트헤더(front header)(21) 및 사이드아웃프레임(22)의 외측 끝단부에 연결되며, 내측판넬(31)의 내측에 내측루프레일(21)이 부착되어 있다.Here, the conventional front column 30, as shown in Figure 2, the inner panel (inner panel) 31 and the outer panel (inner panel) bent in an arbitrary shape coupled to the closed section with a predetermined space Thus, even if the upper end of the outer panel is connected to the side-out frame 22, which is the outer side of the roof panel 20, the front header in which the inner panel 31 is attached to the inside of the front end of the roof panel 20 ( 21 and the outer end of the side-out frame 22, the inner loop 21 is attached to the inner side of the inner panel (31).
한편, 이러한 종래 전면기둥의 상부 정션구조는, 사이드아웃프레임(22)의 안쪽끝과 루프판넬(20)의 외곽부 끝이 각기 절곡되어 서로 겹쳐지게 용착되고, 내측루프레일(31)이 부착되고 프로트헤더(21)에 취부되는 전면기둥의 내측판넬(31)이 사이드아웃프레임(22)과 소정 공간을 두고 분리상태로 배치되어 있다.On the other hand, the upper junction structure of the conventional front column, the inner end of the side-out frame 22 and the outer end of the roof panel 20 is bent and welded to overlap each other, the inner loop 31 is attached The inner panel 31 of the front column mounted on the front header 21 is arranged in a separated state with the side out frame 22 and a predetermined space.
또한, 이러한 종래 전면기둥의 정션부 구조는, 루프판넬(20)을 지지하고 전면 유리와 도어의 상단부를 지지하며, 차량이 전복되거나 충돌사고와 같은 유사시, 루프판넬(20)이나 도어 등이 실내로 침입하는 것을 억제하도록 되어 있다.In addition, the junction structure of the conventional front pillar supports the roof panel 20 and supports the upper ends of the windshield and the door, and in case of a vehicle overturning or a crash, the roof panel 20 or the door is indoors. Intrusion into the
이러한 종래 자동차 전면기등의 정션부 구조는 내측판넬 상단부와 내측루프레일 및 프론트헤더가 단순히 중첩되게 연결되어, 취부강성이 취약하고, 이로 인해 충격이 전달되면 내측판넬과 프론트헤더가 쉽게 분리되어 차체가 실내쪽으로 침입되므로 안전이 위협되는 문제점이 있었다.The junction structure of the conventional front panel of the automobile is such that the inner panel upper end portion, the inner roof rail and the front header are simply superimposed so that the mounting rigidity is weak. There is a problem that the safety is threatened because the invasion into the room.
본 고안은 전면기둥 상단의 정션부 구조를 개선하여 결합강성이 향상되도록 하므로, 정면출돌시 비교적 큰 외력에도 차체 변형이 억제되도록 하고, 이로 인해 정면출돌시 안정성이 향상되도록 하는 데 그 목적이 있다.The present invention is to improve the structure of the junction portion of the top of the front column to improve the coupling stiffness, so that the deformation of the vehicle body to be suppressed even in a relatively large external force during the front run, thereby improving the stability during the front run.

먼저, 본 고안도 도 1과 도 3에 도시되는 바와 같이, 임의의 형상으로 절곡된 전면기둥의 내측판넬(inner panel)(31)과 외측판넬(outer panel)이 소정의 공간을 두고 폐단면으로 결합되어, 내측판넬(31)이 루프판넬(20)의 선단부 내측에 부착되는 프론트헤더(front header)(21) 및 루프판넬(20)의 외측부에 연장되게 형성되는 사이드아웃프레임(22)의 외측 끝단부에 연결된다.First, as shown in Figs. 1 and 3 of the present invention, the inner panel 31 and the outer panel of the front column bent in an arbitrary shape are placed in a closed section with a predetermined space. The outer side of the sideout frame 22 which is coupled to the inner panel 31 is formed to extend to the outer side of the front header 21 and the roof panel 20 attached to the inside of the front end of the roof panel 20 It is connected to the end.
단, 본 고안은 만곡되고 양단이 절곡되는 사이드아웃프레임(22)과 내측판넬(31)의 외측 결합부 사이에 다중으로 절곡 연장되는 내측루프레일(23)의 일단부가 결합되고, 상부로 연장되는 내측루프레일(23)의 중간부가 소정 공간을 두고 사이드아웃프레임(22)의 안쪽 끝과 루프판넬(20)의 외측 끝 결합부 저면에 부착되며, 내측루프레일(23)의 끝단부가 프론트헤더(21)와 내측판넬(31)의 결합부에 고정볼트(24)에 의해 3중으로 결합되어 내측루프레일(23)의 상하 양측이 폐단면이 되도록 구성함을 그 기술적 구성상의 기본 특성으로 한다.However, the present invention is coupled to one end of the inner loop 22 extending in multiple bends between the side out frame 22 and the outer coupling portion of the inner panel 31 is bent and both ends are coupled, extending upward The middle portion of the inner loop 23 is attached to the inner end of the side-out frame 22 and the bottom of the outer end coupling portion of the roof panel 20 with a predetermined space, and the end of the inner loop 23 is the front header ( 21 and the inner panel 31 are coupled to the triple by the fixing bolt 24 is configured so that the upper and lower sides of the inner loop 23 to be a closed cross-section as the basic characteristics of the technical configuration.
이와 같이 구성되는 본 고안은, 내측루프레일(23)이 루프판넬(20)과 프론트헤더(21)에 까지 연장되어 프론트헤더(21)부에 작용하는 응력이 전면기둥의 내측판넬(31)과 루프판넬(20) 쪽으로 분산되도록 하고, 고정볼트(24)가 프론트헤더(21)와 내측판넬(31)의 결합력을 증대시켜, 외력이 작용되는 경우 분리되려는 것을 효과적으로 억제하게 된다.According to the present invention configured as described above, the inner loop rail 23 extends to the roof panel 20 and the front header 21 so that the stress acting on the front header 21 is applied to the inner panel 31 of the front column. To be distributed toward the roof panel 20, the fixing bolt 24 increases the coupling force of the front header 21 and the inner panel 31, thereby effectively suppressing the separation when the external force is applied.
상기와 같이 구성되고 작동하는 본 고안은, 전면기둥 상단의 정션부 구조가 루프판넬에 부착되는 내측루프레일과 내측판넬이 고정볼트에 의해 프론트헤더에 결합되어, 결합강성이 향상되도록 하므로, 정면충돌시 비교적 큰 외력에도 차체 변형이 억제되도록 하고, 이로 인해 안전성이 향상되도록 하는 효과를 갖는다.The present invention is constructed and operated as described above, the inner loop and the inner panel is attached to the front header by the fixing bolt to the junction portion structure of the top of the front column is fixed to the roof panel, so that the coupling rigidity is improved, the front collision When the vehicle body deformation is suppressed even at a relatively large external force, this has the effect of improving safety.
본 고안은 자동차 전면기둥의 정션부 구조에 관한 것으로서, 그 구조를 개선하여 정면에서 충격이 가해지는 경우 전면기둥이 실내쪽으로 침입하는 것을 억제하여 안전성이 향상되도록 하는 데 그 목적이 있다.The present invention relates to the structure of the junction portion of the front pillar of the car, the purpose of improving the structure to suppress the intrusion into the interior of the front pillar when the impact is applied from the front to improve the safety.
