본 고안은 자동차 측면 하부의 차체구조에 관한 것으로서, 특히 승원의 안전성을 향상시켜 주기 위해, 차량의 측부 충돌시, 사이드실(side sill)이 차실내로 침입되는 것을 효과적으로 억제하도록 하는 자동차 사이드실의 보강구조에 관한 것이다.The present invention relates to the body structure of the lower side of the vehicle, in particular, to improve the safety of the occupant, the side of the vehicle (side sill) during the side collision of the vehicle (side sill) to effectively prevent the entry into the interior of the vehicle It relates to a reinforcement structure.

일반적으로 자동차의 측면부 자제구조는, 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)의 일측단부가 내측판넬의 일측부에 취부되어 있다.In general, the side control structure 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 that forms an outer portion of the roof is connected to an upper end portion, and one end of a floor panel forming a bottom portion of the vehicle is attached to one side of the inner panel.

여기에서, 종래 자동차 사이드실의 보강구조는 제1도에 도시되는 바와 같이, 절곡된 내측판넬(inner panel)(11)과 외측판넬(outer panel)(12)이 소정의 공간을 두고 폐단면으로 결합되고, 상기 폐단면 내부에서 내측판넬(11)과 외측판넬(12) 사이에 사이드실보강판(reinforcement)(13)의 상단부와 하단부가 부착되며, 플로어판넬(20)의 측단부가 절곡되어 내측판넬(11)의 외측면에 연결되어 있다.Here, the reinforcement structure of the conventional side wall of the vehicle, as shown in FIG. 1, the bent inner panel (11) and the outer panel (outer panel) 12 to the closed section with a predetermined space The upper and lower ends of the side seal reinforcement plate 13 are attached between the inner panel 11 and the outer panel 12 in the closed end surface, and the side ends of the floor panel 20 are bent. It is connected to the outer side of the inner panel 11.

이와같이 구성되는 종래 자동차 실사이드의 보강구조는, 도어(30)의 하단부가 외측판넬(12)의 상단부에 일정폭 수납되도륵 되어, 측면충돌시 외측판넬(12)에 의해 1차적으로 충격에너지를 흡수하고, 충격하중을 사이드실보강판(13) 및 내측판넬(11)을 통해 플로어판넬(20)로 분산시키고, 측부 구조물인 도어(30)가 실내로 침입되는 것을 억제하며, 사이드실보강판(13)이 2차적으로 충격에너지를 흡수하도록 하여, 측부 차ㅊ의 변형을 억제하고 실내의 승원이 보호되도록 되어 있다.In the reinforcement structure of the conventional vehicle seal side configured as described above, the lower end portion of the door 30 may be accommodated in the upper end portion of the outer panel 12 at a predetermined width, and the impact energy is primarily absorbed by the outer panel 12 during side impact. Absorbs and distributes the impact load to the floor panel 20 through the side seal reinforcing plate 13 and the inner panel 11, and suppresses the door 30, which is a side structure, from entering the room, and the side seal reinforcing plate (13) allows secondary energy to be absorbed so as to suppress deformation of the side shaft and protect the occupants of the room.

그러나, 이러한 종래 자동차 사이드실의 보강구조는, 측면 충돌시, 충돌하는 차량의 범퍼 하부쪽에 사이드실(10)과 플로어판넬(20)이 위치되어 비교적 큰 하중이 집중되기 때문에, 충격이 가해진 사이드실(10)의 충격부위가 파손되어 폐단면이 제거됨으로서, 대형사고시 도어(30)와 함께 측면부 차체가 실내로 침입하게 되는 문제점이 있었다.However, such a reinforcement structure of the conventional side wall of the vehicle is that the side seal 10 and the floor panel 20 are located at the lower side of the bumper of the colliding vehicle during side impact, so that a relatively large load is concentrated. As the impact portion of the 10 is broken and the closed cross section is removed, there is a problem that the side body along with the door 30 penetrates into the room during a large accident.

본 고안의 목적은 상기와 같은 종래의 문제점을 보완하기 위해, 사이드실보강판(13)과 내측판넬이 취부되며 형성된 폐단면 내부에 일측단부가 플로어판넬에 취부된 보강바에 의해 일측면이 지지되는 격벽판을 취부하여, 차량의 측면으로 충격이 가해지는 경우 충격에너지에 의해 내측판넬과 외측판넬이 취부되며 형성된 폐단면이 손상되는 것을 억제하고, 충격하중을 측면부 차체에 폭넓게 분산되도록 하는 동시에, 차체의 변형량을 억제 하도록 하는 자동차 사이드실의 보강구조를 제공하는 데 있다.The purpose of the present invention is to supplement the conventional problems as described above, one side of the side seal reinforcement plate 13 and the inner panel is mounted and one side is supported by a reinforcing bar mounted on the floor panel inside the closed end surface formed When the partition plate is mounted and the impact is applied to the side of the vehicle, the impact energy is mounted on the inner panel and the outer panel to prevent damage to the closed end surface formed, and the impact load is widely distributed on the side body. It is to provide a reinforcement structure of the vehicle side seal to suppress the amount of deformation.

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 사이드실의 보강구조도 제 2 도에 도시되는 바와 같이, 절곡된 내측판넬(11)과 외측판넬(12)이 소정의 공간을 두고 폐단면으로 결합되고, 상기 폐단면 내부에서 내측판넬(11)과 외측판넬(12) 사이에 사이드실보강판(13)의 상단부와 하단부가 부착되며, 내측판넬(11)의 외측면에 플로어판넬(20)의 일측단부가 취부되는 그 기술적 사상은 종래와 같다 하겠다. 단, 본 고안은 상기 내측판넬(11)과 사이드실보강판(13)에 요홈(15)이 형성되고, 외측판넬(12)의 내측면 상부와 하부에는 격벽판(50)의 양측단부가 취부되며, 상기 격벽판(50)의 일측면에는 타측단부가 플로어판넬(20)에 취부된 지지바(40)가 설치됨용 그 기술적 구성상의 기본 특징으로 한다.As shown in FIG. 2, the bent inner panel 11 and the outer panel 12 are coupled to the closed end face with a predetermined space, and the inner side of the closed end face is shown in FIG. 2. The upper and lower ends of the side seal reinforcing plate 13 is attached between the panel 11 and the outer panel 12, the technical idea that one side end of the floor panel 20 is mounted on the outer surface of the inner panel (11) Will be the same as before. However, in the present invention, grooves 15 are formed in the inner panel 11 and the side seal reinforcement plate 13, and both side ends of the partition plate 50 are mounted on the upper and lower inner surfaces of the outer panel 12. On one side of the partition plate 50, the other end is a basic feature of the technical configuration for the support bar 40 is installed on the floor panel 20 is installed.

이와같이 구성되는 본 고안은, 측면 충돌시 외측판넬(12)에 의해 1차적으로 충격에너지를 흡수하고 충격하중이 분산되도록 하며, 2차적으로 외측판넬(12)의 내측면에 양측단부가 취부된 격벽판(50)이, 일측단부가 플로어판넬(20)에 취부된 지지바(40)와 연계하여 충격에너지를 흡수하고, 사이드실보강판(13)과 내측판넬(11)이 접하며 형성된 폐단면과 연계하여, 실내쪽으로 작용하는 충격하중을 흡수하고, 차체의 횡방향으로 폭넓게 하중을 분산시켜, 실내로 전달되는 충격을 완충시켜 주고, 도어(30) 및 측부 차체가 실내로 침입되는 것을 효과적으로 억제시켜 준다.According to the present invention configured as described above, a partition wall having both side ends mounted on an inner surface of the outer panel 12 secondarily absorbs impact energy and distributes an impact load by the outer panel 12 during side impact. The plate 50 has a closed end surface formed by absorbing impact energy in connection with a support bar 40 mounted at one side of the floor panel 20, and contacting the side seal reinforcing plate 13 and the inner panel 11. By linking, it absorbs the impact load acting toward the interior, distributes the load widely in the transverse direction of the vehicle body, buffers the shock transmitted to the interior, and effectively suppresses the door 30 and the side vehicle body from entering the interior. give.

따라서, 이러한 본 고안은 자체의 변형이 억제되고, 충격이 효과적으로 완충되어, 측면 충돌시 승원의 안전성이 향상되도록 하는 효과가 있다.Therefore, the present invention has the effect of suppressing its deformation, effectively cushioning the impact, and improving the safety of the occupant during side impact.

이상에서 살펴본 바와 같이, 본 고안은 폐단면으로 형성되는 사이드실의 내부에 격벽판이 지지바에의한 지지률 받으며 사이드실의 폐단면 내부에 설치되어, 정면및 측면 충돌시 차체의 변형을 억제하여, 차체의 실내 침입을 억제하고 충격을 효과적으로 완충하도록 하는 매우 유용한 것이다.As described above, the present invention is installed in the closed end surface of the side chamber with the partition plate is supported by the support bar in the interior of the side chamber formed as a closed cross-section, to suppress the deformation of the vehicle body in the front and side collision, It is very useful to suppress the vehicle's intrusion into the room and effectively cushion the impact.
