Description

중간기둥의 구조Structure of the middle column

본 발명은 자동차의 도어(door) 외곽부가 밀착되는 중간기둥부의 구조에 관한 것으로서, 중간기둥의 보강구조를 개선하여 그 강성이 향상되도록 하는 것이다.The present invention relates to a structure of an intermediate pillar in which a door outer portion of a vehicle is in close contact, and to improve the stiffness of the intermediate pillar by improving its reinforcing structure.

일반적으로 자동차의 중간기둥은 차체의 양측부에 형성되는 개구부 중간에 상파 단부가 지붕과 플로어에 연결되어 중간기둥의 양측에 각기 도어가 개폐되도록 설치되어 있다.In general, the middle pillar of the vehicle is installed so that the upper end is connected to the roof and the floor in the middle of the opening formed in both sides of the vehicle body so that the doors are opened and closed on both sides of the intermediate pillar.

여기에서, 종래 중간기둥의 구조는 도 1에 도시되는 바와 같이, 임의의 형상으로 절곡 형성되는 내측판넬(12)과 외측판넬(11)이 소정 공간을 형성하며 폐단면으로 결합되고, 상기 폐단면 사이에 보강판(13)이 장착되며, 상기 폐단면 중간에 원통 파이파형의 임팩트바(14)가 보강판(13)에 지지되도록 장착되어, 내측판넬(12)쪽 외부면에 트림가 취부되고, 외측판넬(11) 외부면에 도어가 밀착되도록 하는 웨더스트립이 리테이너에 의해 밀착되게 취부되도록 되어 있다.Here, in the structure of the conventional intermediate column, as shown in FIG. 1, the inner panel 12 and the outer panel 11, which are formed to be bent in an arbitrary shape, form a predetermined space and are coupled to a closed cross section, and the closed cross section A reinforcement plate 13 is mounted therebetween, and a cylindrical pie wave impact bar 14 is mounted to be supported by the reinforcement plate 13 in the middle of the closed end surface, and a trim is mounted on the outer surface of the inner panel 12 side. A weatherstrip for allowing the door to be in close contact with the outer surface of the outer panel 11 is mounted to be in close contact with the retainer.

이와 같이 구성되는 종래 중간기둥의 구조는, 하단부가 플로어에 지지되어 상단부에 의해 지붕을 지지하고, 보강판(13)과 임팩트바(14)에 의해 그 강성이 향상되도록 되며, 웨더스트립에 의해 차체 측면 개구부에 닫히는 도어의 외곽부가 탄력적으로 접촉되도록 하므로 도어의 닫힘이 조용하고 닫힌 상태가 기밀하도록 되어 있다.In the structure of the conventional intermediate column configured as described above, the lower end is supported by the floor to support the roof by the upper end, and the rigidity is improved by the reinforcement plate 13 and the impact bar 14, and the vehicle body by the weather strip. Since the outer part of the door closing to the side opening is elastically contacted, the door is closed and the closed state is airtight.

이러한 종래 자동차의 중간기둥 구조는, 보강구조가 상하 종방향으로 만 형성되어 측부 충돌시 변형이 쉽게 일어나는 단점이 있었다.The middle pillar structure of such a conventional vehicle, the reinforcement structure is formed only in the vertical direction up and down has a disadvantage that deformation easily occurs during side impact.

본 발명은 중간기둥의 보강구조를 개선하여 횡방향 충돌에 대한 강성이 향상되도록 하므로, 충돌에 대한 변형을 효율적으로 억제하도록 하는데 그 목적이 있다.The present invention is to improve the rigidity of the intermediate column to improve the stiffness to the lateral collision, the object is to efficiently suppress the deformation to the collision.

먼저, 본 발명도 도 2에 도시되는 바와 같이, 임의의 형상으로 절곡 형성되는 내측판넬(12)과 외측판넬(11)이 소정 공간을 형성하며 폐단면으로 결합되고, 상기 폐단면 사이에 보강판(13)이 장착되며, 상기 폐단면 중간에 원통 파이파형의 임팩트바(14)가 보강판(13)에 지지되도록 장착되어, 내측판넬(12)쪽 외부면에 트림가 취부되고, 외측판넬(11) 외부면에 도어가 밀착되도록 하는 웨더스트립이 리테이너에 의해 밀착되게 취부되도록 된다.First, as shown in FIG. 2, the present invention also includes an inner panel 12 and an outer panel 11 that are bent in an arbitrary shape to form a predetermined space and are coupled to a closed cross section, and a reinforcing plate between the closed cross sections. (13) is mounted, and a cylindrical pie wave shaped impact bar 14 is mounted on the reinforcing plate 13 in the middle of the closed end surface, and a trim is mounted on the outer surface of the inner panel 12 side, and the outer panel 11 The weatherstrip, which allows the door to be in close contact with the outer surface, is to be attached by the retainer.

단, 본 발명은 보강판(13)과 내측판넬(12) 사이에 절곡 형성되는 제 2 보강판(15)이 폐단면을 형성하며 장착됨을 그 기술적 구성상의 기본 특징으로 한다.However, the present invention is a basic feature of the technical configuration that the second reinforcing plate 15 is formed between the reinforcing plate 13 and the inner panel 12 is formed to form a closed cross section.

이와 같이 구성되는 본 발명은, 내측판넬(12)과 외측판넬(11) 내부에 보강판(13)과 임팩트바(14) 및 제 2 보강판(15)에 의해 복수개의 폐단면 구조가 형성되어, 외측에서 충격하중이 작용되면 상기 복수개의 폐단면 구조가 다중으로 충격을 흡수하도록 하고, 상기 복수개의 폐단면 구조가 서로 응력을 분산시켜 횡방향 및 종방향 강성이 향상되도록 한다.In the present invention configured as described above, a plurality of closed cross-sectional structures are formed by the reinforcing plate 13, the impact bar 14, and the second reinforcing plate 15 inside the inner panel 12 and the outer panel 11. When the impact load is applied from the outside, the plurality of closed cross-sectional structures absorb shocks in multiple, and the plurality of closed cross-sectional structures distribute stresses to each other to improve lateral and longitudinal stiffness.

상기와 같이 구성되고 작동되는 본 발명은, 내측판넬과 외측판넬 사이에 복수개의 폐단면 구조가 형성되어 강성이 향상되고, 각 방향에서 작용하는 하중을 효과적으로 분산시켜 충격을 완충하도록 하므로 충격에 대한 안전성이 향상되도록 하는 효과를 갖는다.The present invention constructed and operated as described above has a plurality of closed cross-sectional structures formed between the inner panel and the outer panel to improve rigidity, and effectively disperse the load acting in each direction so as to cushion the impact, thereby ensuring safety against impact. This has the effect of being improved.
