본 발명은 자동차 측면에 설치되는 중간기둥의 보강구조에 관한 것으로서, 특히 승원의 안전성을 향상시켜 주기 위해, 차량의 측부 충돌시, 중간기둥이 파손되는 것을 효과적으로 억제하도록 하는 자동차 중간기둥의 보강구조에 관한 것이다.The present invention relates to a reinforcement structure of an intermediate pillar installed on the side of an automobile, and in particular, to improve the safety of the occupant, to a reinforcement structure of an automobile intermediate pillar that effectively suppresses breakage of the intermediate pillar during side collision of the vehicle. It is about.

일반적으로 자동차의 측면부 차체구조는, 전면기둥(front pillar)과 중심기둥(center pillar) 및 후면기둥(rear pillar) 사이에 개구부가 형성되어, 상기 개구부에 도어가 개폐 가능하게 설치되고, 상기 기둥들 상단부에 지붕의 외측부를 형성하는 루프레일(roof rail)이 연결되며, 상기 기둥들 하단부에 차량의 저면부를 형성하는 플로어판넬(floor panel)과 사이드실(side sill)이 연결되어 있다.In general, the vehicle body structure of the side portion of the vehicle, the opening is formed between the front pillar (center pillar) and the center pillar (center pillar) and rear pillar (rear pillar), the door is installed to open and close the opening, the pillars A roof rail which forms an outer portion of the roof is connected to the upper end, and a floor panel and a side sill, which form a bottom portion of the vehicle, are connected to the lower end of the pillars.

여기에서, 종래 자동차 중간기둥의 보강구조는 제 1 도와 제 2 도에 도시되는 바와 같이, 절곡된 내측판넬(12:INNER PANEL)과 외측판넬(11:OUTER PANEL)이 소정의 공간을 두고 폐단면으로 결합되고, 상기 폐단면의 내부에는 좌우 양측이 절곡되어 플랜지가 형성된 제1보강판(13)이 외측판넬(11:OUTER PANEL)의 내측면에 접하며 취부되며, 상기 제1보강판(13)의 플랜지는 외측판넬(11)과 내측판넬(12)이 취부되어진 취부부에 취부되어 진다.Here, in the conventional reinforcement structure of the intermediate pillar of the vehicle, as shown in FIGS. 1 and 2, the bent inner panel 12 and the outer panel 11 have a predetermined space with a closed end surface. Coupled to the inside of the closed end surface, the left and right sides are bent and the first reinforcing plate 13 having a flange is formed in contact with the inner surface of the outer panel 11, the first reinforcing plate (13) The flange of is mounted on the mounting portion where the outer panel 11 and the inner panel 12 are mounted.

이와같이 구성되는 종래 자동차 중간기둥의 보강구조는, 내측판넬(12)과 외측판넬(11)이 취부되어진 폐단면 내부에 제1보강판(13)이 외측판넬(11)의 내측면과 접하며 취부되어, 측부 구조물인 중간기둥(100)이 파손되어 실내로 침입되는 것을 억제 흡수하도록 하여, 측부 차체의 변형을 억제하고 실내의 승원이 보호되도록 되어 있다.The reinforcement structure of the conventional automobile intermediate pillar configured as described above, the first reinforcing plate 13 is mounted in contact with the inner surface of the outer panel 11 in the closed end surface on which the inner panel 12 and the outer panel 11 is mounted. In addition, the intermediate pillar 100, which is a side structure, is prevented and absorbed from being broken and invaded into the room, thereby suppressing deformation of the side vehicle body and protecting the occupant of the room.

그러나, 이러한 종래 자동차 중간기둥의 보강구조는, 측면 충돌시 충돌하는 외측판넬(11)의 내측면과 종방향으로 접하며 외측판넬(11)과 내측판넬(12)이 취부되어진 취부부에 플랜지 되어있는 제1보강판(13)에 의해 충격에너지를 흡수하여야 하므로 제기능을 발휘하지 못하고, 중간기둥(100)이 충격에 의해 파손되어 차체가 실내로 침입하게 되는 문제점이 있었다.However, the conventional reinforcement structure of the intermediate pillar of the vehicle is in contact with the inner surface of the outer panel 11 which collides in the side collision in the longitudinal direction and is flanged to the mounting portion on which the outer panel 11 and the inner panel 12 are mounted. Since the impact energy must be absorbed by the first reinforcing plate 13, the first reinforcing plate 13 may not function properly, and the intermediate pillar 100 may be damaged by the impact, and the vehicle body may enter the room.

본 발명의 목적은 상기와 같은 종래의 문제점을 보완하기 위해, 폐단면으로 형성되는 중간기둥의 내부에 제2보강판(REINFORCEMENT)를 장착하여, 측면 충돌시 상기 중간기둥의 내부에서 충격에너지를 흡수하는 동시에 충격하중에 의하여 도어가 차실로 유입되는 것을 억제 하도록 하는 자동차 중간기둥의 보강구조를 제공하는 데 있다.An object of the present invention is to supplement the conventional problems as described above, by mounting a second reinforcing plate (REINFORCEMENT) in the interior of the intermediate column formed as a closed cross-section, absorbing the impact energy in the interior of the intermediate column during side impact At the same time to provide a reinforcement structure of the middle pillar of the car to suppress the door from entering the vehicle compartment by the impact load.

이하 첨부된 도면에 의하여 본 발명의 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration of the present invention with reference to the accompanying drawings in detail.

본 발명의 자동차 중간기둥의 보강구조도 제 4 도와 제 5 도에 도시되는 바와 같이, 절곡된 내측판넬(12:INNER PANEL)과 외측판넬(11:OUTER PANEL)이 소정의 공간을 두고 폐단면으로 결합되고, 상기 폐단면의 내부에는 좌우 양측이 절곡되어 플랜지가 형성된 제1보강판(13)이 외측판넬(11:OUTER PANEL)의 내측면과 접하며 취부되며, 상기 제1보강판(13)의 플랜지는 외측판넬(11)과 내측판넬(12)이 취부되어진 취부부에 취부되어 되는 것에 있어서, 상기 내측판넬(12:INNER PANEL)의 내측면과 제1보강판(13)내측면과 접하도록 평탄면(25)의 일측단부가 상부로 절곡되어 취부부(22)가 형성되고, 상기 평탄면(25)의 타측단부는 하부로 절곡되어 플랜지(23)가 형성되며, 상기 평탄면(25) 중앙에는 제1보강판(13)을 통하여 전달되는 충격에너지를 흡수하도록 하는 통공(21)이 형성된 제2보강판(20)이 설치됨을 그 기술적 구성상 기본 특징으로 한다.As shown in FIGS. 4 and 5 of the reinforcing structure of the automobile intermediate pillar of the present invention, the bent inner panel 12 and the outer panel 11 have a predetermined space in a closed section with a predetermined space. The first reinforcement plate 13 is coupled to the inside of the closed end surface and the left and right sides are bent to be in contact with the inner surface of the outer panel (11: OUTER PANEL) is mounted, the first reinforcing plate of the The flange is mounted on the mounting portion on which the outer panel 11 and the inner panel 12 are mounted so that the flange contacts the inner surface of the inner panel 12 and the inner side of the first reinforcing plate 13. One side end of the flat surface 25 is bent upwards to form a mounting portion 22. The other end of the flat surface 25 is bent downward to form a flange 23, and the flat surface 25 is formed. The second reinforcing plate (2) having a through-hole 21 is formed in the center to absorb the impact energy transmitted through the first reinforcing plate (13) 0) is installed as a basic feature of the technical configuration.

이와 같이 구성되는 본 발명은, 측면 충돌시 보강판(40)이 취부된 외측판넬(11)에 의해 1차적으로 충격에너지를 흡수하고 충격하중이 분산되도록 하며, 2차적으로 제1보강판(13)의 내측면과 내측판넬(12)의 내측면과 접하며 취부된 제2보강판(20)의 평탄면에 형성된 통공(21)에서 충격하중을 흡수함과 동시에 평탄면(25)을 통해 내측판넬(12)로 분산시키며, 3차적으로 제2보강판(20)의 일측면에 취부된 내측판넬(12)이 충격에너지를 흡수함과 동시에 횡방향으로 폭넓게 하중을 분산시켜, 실내로 전달되는 충격을 완충시켜 주고, 측부 차체가 실내로 침입되는 것을 효과적으로 억제시켜 준다.According to the present invention configured as described above, the impact panel is primarily absorbed by the outer panel 11 in which the reinforcing plate 40 is mounted during side impact, and the impact load is dispersed, and the first reinforcing plate 13 is secondary. ) Absorbs the impact load in the through hole 21 formed in the flat surface of the second reinforcing plate 20 mounted in contact with the inner surface of the inner panel 12 and the inner panel 12 and at the same time the inner panel through the flat surface 25. The inner panel 12 attached to one side of the second reinforcing plate 20 absorbs the impact energy and distributes the load widely in the transverse direction, and is transmitted to the room. It cushions and effectively suppresses the side vehicle body from entering the room.

따라서, 이러한 본 발명은 제2브라켓(20)의 평탄면(25)의 좌우 양측으로 절곡되어 형성된 취부부(22)와 플랜지(23)가 중간기둥(100)의 폐단면 내부에 취부되어진 제1보강판(13)의 내측면과 내측판넬(12)의 내측면에 각각 취뷔되어, 중간기둥(100)이 횡방향에 대한 강성을 향상시켜, 측면충돌시 충격에너지에 의해 중간기둥(100)이 파손되는 것이 억제되고, 차체의 변형이 억제되며, 충격에너지가 효과적으로 완충되어, 측면 충돌시 승원의 안전성이 향상되도록 하는 효과가 있다.Therefore, in the present invention, the mounting part 22 and the flange 23 formed by bending to the left and right sides of the flat surface 25 of the second bracket 20 are mounted inside the closed end surface of the intermediate column 100. The inner side of the reinforcing plate 13 and the inner side of the inner panel 12, respectively, is taken up, the intermediate column 100 to improve the stiffness in the transverse direction, the middle column 100 by the impact energy during side impact The damage is suppressed, the deformation of the vehicle body is suppressed, the impact energy is effectively buffered, and there is an effect of improving the safety of the occupant during side impact.

이상에서 살펴본 바와 같이, 본 발명은 폐단면으로 형성되는 중간기둥의 내부에 제2보강판 이 취부되어, 측면 충돌시 중간기둥이 파손되어 실내로 침입되는 것을 억제하고 충격을 효과적으로 흡수, 완충하도록 하는 매우 유용한 것이다.As described above, the present invention has a second reinforcing plate is mounted in the interior of the intermediate column formed as a closed cross-section, to prevent the middle column is broken into the room during side impact and to effectively absorb and cushion the shock It is very useful.
