본 고안은 자동차 중심기둥(center pillar)의 구조에 관한 것으로, 특히 중심기둥의 판넬구조를 개선하여, 중간부에 작용되는 벤딩모우먼트(bending moment)에 대한 강성이 향상되도록 하는 자동차 중심기둥의 보강구조에 관한 것이다.The present invention relates to the structure of the center pillar of the automobile, and in particular, to improve the panel structure of the center pillar, the reinforcement of the center pillar of the automobile to improve the rigidity for the bending moment (bending moment) acting in the middle portion It's about structure.
일반적으로 자동차의 측면부 차체는, 제1도에 도시되는 바와 같이, 양측면부에 전면기둥(front pillar)(10)과 중심기둥(center pillar)(20) 및 후면기둥(rear pillar)(30)이 상부로 연장되고 상기 기둥들 사이에 각기 도어가 설치되도록 하는 개구부가 형성되어, 전면기둥(10)과 중심기둥(20) 및 후면기둥(30)의 상단부에 지붕의 외곽부를 형성하는 루프레일(roof rail)(40)이 연결되고, 상기 기둥들의 하단부가 차량의 저면부를 형성하는 플로어판넬(floor panel) 및 사이드실(side sill)(50)에 연결되어 있다.In general, as shown in FIG. 1, a vehicle body having a front pillar 10, a center pillar 20, and a rear pillar 30 at both side surfaces thereof, as shown in FIG. An opening is formed to extend upward and to allow the doors to be installed between the pillars, thereby forming a roof rail at the upper end of the front pillar 10, the central pillar 20, and the rear pillar 30. A rail 40 is connected, and lower ends of the pillars are connected to a floor panel and a side sill 50 forming a bottom portion of the vehicle.
여기에서, 중심기둥(20)은 제2도에 도시되는 바와 같이, 양측부가 절곡되어 플랜지(flange)가 형성되는 내측판넬(inner panel)(21)과 외측판넬(outer panel)(22)이 소정의 공간을 두고 양측 외곽부인 상기 플랜지가 폐단면으로 결합되며, 상기 공간 내부에서 내측파넬(21)과 외측판넬(22) 사이에 보강판(reinforcement)(23)의 양측 연부가 일체로 결합되어 있다.Here, as shown in FIG. 2, the center pillar 20 has an inner panel 21 and an outer panel 22 in which both sides are bent to form a flange. The flanges, which are outer edges on both sides of the space, are coupled to the closed end surface, and both edges of the reinforcement 23 are integrally coupled between the inner panel 21 and the outer panel 22 in the space. .
한편, 이러한 종래 자동차의 중심기둥(20)은, 내측판넬(21)의 하단부가 플로어판넬에 연결되고, 외측판넬(22)의 하단부가 사이드실(50)에 연결되어, 상단부가 지붕을 지지하고, 양측부에 도어가 밀착되도록 되어 있다. 또한, 차량의 측면부에 충격하중이 전달되면, 상하 양단부에 의해 루프레일(40)과 사이드 실(50)에 하중을 분산시켜, 충돌한 차량 및 도어가 실내로 침입하는 것을 억제하도록 되어 있다.On the other hand, the center pillar 20 of such a conventional vehicle, the lower end of the inner panel 21 is connected to the floor panel, the lower end of the outer panel 22 is connected to the side chamber 50, the upper end supports the roof The door is in close contact with both sides. In addition, when the impact load is transmitted to the side surface of the vehicle, the load is distributed to the roof rail 40 and the side seal 50 by the upper and lower ends so as to prevent the collision of the vehicle and the door from entering the room.
그러나, 이러한 종래 자동차의 중심기둥은, 측면 충돌사고시, 충돌하는 차량의 범퍼 및 전면부가 중심기둥(20)의 중간부에 부딪히게 되어, 중심기둥(20)에 벤딩모우먼트가 작용하게 되는데, 중심기둥(20)의 양측부만 절곡되고 양측부 사이의 중간부가 평면구조로 형성되어 있기 때문에, 충돌시 벤딩하중이 전달되면, 이를 견디지 못하고 중간부가 쉽게 꺽이게 되어, 승원의 안전이 위협을 받게 되는 문제점이 있었다.However, the center pillar of such a conventional vehicle, in the event of a side collision, bumper and the front portion of the colliding vehicle hit the middle of the center pillar 20, the bending moment acts on the center pillar 20, the center Since only the both sides of the pillar 20 are bent and the middle portion between the two sides is formed in a planar structure, if a bending load is transmitted during a collision, the middle portion is easily torn, and the middle portion is easily bent, and the safety of the crew is threatened. There was a problem.
본 고안의 목적은 상기와 같은 종래의 문제점을 보완하기 위해, 중심기둥의 판넬 중간부가 축방향으로 따라 절곡 돌출되도록 형성하여, 벤딩에 대한 변형을 효과적으로 억제하도록하는 자동차 중심기둥의 보강구조를 제공하는 데 있다.An object of the present invention is to provide a reinforcement structure of the automobile center pillar to effectively suppress the deformation to be formed by forming a middle portion of the panel panel bent protruding along the axial direction in order to supplement the conventional problems as described above. There is.
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 중심기둥도 제3도에 도시되는 바와 같이, 양측부가 절곡되어 플랜지(flange)가 형성되는 내측판넬(21)과 외측판넬(22)이 소정의 공간을 두고 양측 외곽부인 상기 플랜지가 폐단면으로 결합되며, 상기 공간내부에서 내측판넬(21)과 외측판넬(22) 사이에 보강판(23)의 양측 연부가 일체로 결합되는 것은 종래와 같다. 단, 본 고안은 상기 폐단면으로 결합되는 중심기둥(20)의 판넬 중감주가 축방향을 따라 일측으로 돌출되게 일정폭 절곡 형성됨을 그 기술적 구성상의 기본 특지으로 한다.As shown in FIG. 3 of the center pillar of the present invention, the flange, which is the outer side of both sides of the inner panel 21 and the outer panel 22, on which both sides are bent to form a flange, has a predetermined space and is closed. Coupled to the surface, both edges of the reinforcing plate 23 is integrally coupled between the inner panel 21 and the outer panel 22 in the space as in the prior art. However, the present invention is a basic feature of the technical configuration that the panel centered persimmon of the center column 20 coupled to the closed end surface is formed to be bent in a predetermined width along the axial direction.
여기에서, 중간기둥(20)은 제1실시예로서 제3도에 도시되는 바와 같이, 보강판(23)의 중간부에 절곡부가 형성되도록 함이 바람직하다.Here, as shown in FIG. 3 as the first embodiment, the intermediate pillar 20 is preferably such that a bent portion is formed in the middle portion of the reinforcing plate 23.
한편, 본 고안은 다른 실시예로서, 제4도에 도시되는 바와 같이, 보강판(23)의 중간부와 내측판넬(21)의 중간부에 각기 절곡부가 형성되도록 구성할 수도 있다.On the other hand, the present invention as another embodiment, as shown in Figure 4, may be configured such that the bent portion is formed in the middle portion of the reinforcing plate 23 and the middle portion of the inner panel 21, respectively.
이와 같이 구성되는 본 고안은, 외측에서 하중이 전달되면, 보강판(23) 및 내측판넬(21)의 절곡 돌출된 중간부위로 인해, 부분적으로 전단응력이 작용되게 되어, 벤딩모우먼트에 대한 저항력 및 외력에 대한 항복응력이 향상되게 된다.The present invention configured as described above, when the load is transmitted from the outside, due to the bent and protruding intermediate portion of the reinforcing plate 23 and the inner panel 21, the shear stress is partially acted, the resistance to the bending moment And yield stress against external force is improved.
따라서, 이러한 본 고안은 보강효과가 효율적이 되어, 차량의 측면부에 외력이 가해지는 경우, 중간부가 꺽이는 것을 억제하고, 폐단면으로 결합되는 중심기둥(20)의 전체 강성이 향상되도록하여, 측면 충돌과 같은 유사시, 추돌한 차량 및 차체가 실내로 침입하는 것을 효과적으로 제지하므로, 승원의 안전성이 향상되도록 한다.Therefore, the present invention is effective in reinforcing effect, when the external force is applied to the side of the vehicle, the middle portion is prevented from bending, so that the overall rigidity of the center column 20 coupled to the closed section is improved, side impact In such a case, since the collision of the colliding vehicle and the vehicle body is effectively restrained, the safety of the occupant is improved.
이상에서 살펴본 바와 같이, 본 고안은 중심기둥의 판넬 중간부가 축방향을 따라 절곡 돌출되어, 벤딩에 대한 변형이 억제되도록 하므로, 유사시 중심기둥의 파손 및 실내 침입을 억제하여 주는 매우 유용한 것이다.As described above, the subject innovation is to be bent and protruded along the axial direction of the panel middle portion of the central column, so that the deformation of the bending is suppressed, it is very useful to suppress the breakage and intrusion of the center column in case of emergency.
