본 발명의 자동차 측면 하부의 차체구조에 관한 것으로서, 특히 승원의 안전성을 향상시켜 주기 위해, 차량의 측부 충돌시, 사이드실(side sill)이 실내로 침입되는 것을 효과적으로 억제하도록 하는 자동차 사이드실의 보강구조에 관한 것이다.The present invention relates to a vehicle structure of the lower side of an automobile, and in particular, in order to improve the safety of the occupant, reinforcement of the automobile side seal to effectively suppress the entry of a side sill into a room during a side collision of the vehicle. It's about structure.
일반적으로 자동차의 측면부 차체구조는, 전면기둥(front pillar)과 중심기둥(center pillar) 및 후면기둥(rear pillar) 사이에 개구부가 형성되어, 상기 개구부에 도어가 개폐가능하게 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 the 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 사이드실의 보강구조는 제1도에 도시되는 바와같이, 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 사이드실 보강판(13)이 상단부와 하단부가 부착되며, 플로어판넬(20)의 측단부에 내측판넬(11)의 외측면이 연결되어 있다.Here, the reinforcing structure of the conventional vehicle side chamber is a bent inner panel (11) and the outer panel (outer panel) 12, as shown in Figure 1, a predetermined cross-sectional space to the closed section The side seal reinforcement plate 13 is attached between the inner panel 11 and the outer panel 12 in the closed end surface, and the upper end and the lower end are attached, and the inner panel 11 at the side end of the floor panel 20. The outer side of is connected.
이와 같이 구성되는 종래 자동차 실사이드의 보강구조는, 도어의 하단부가 외측판넬(12)의 상단부에 일정폭 수납되도록 되어, 측면 충돌시 외측판넬(12)에 1차적으로 충격에너지를 흡수하고, 충격하중을 사이드실보강판(13) 및 내측판넬(11)을 통해 플로어판넬(20)로 분산시키고, 측부 구존물인 도어가 실내로 침입되는 것을 억제하며, 사이드실 보강판(13)이 2차적으로 충격에너지를 흡수하도록 하여, 측부 차체의 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 is accommodated in the upper end portion of the outer panel 12 at a predetermined width, so that the impact energy is primarily absorbed by the outer panel 12 during side impact, and the impact The load is distributed to the floor panel 20 through the side seal reinforcing plate 13 and the inner panel 11, and the door which is a side reinforcement is prevented from entering the room, and the side seal reinforcing plate 13 is secondarily By absorbing the impact energy, the deformation of the side vehicle body is suppressed and the occupant of the room is protected.
그러나, 이러한 종래 자동차 실사이드의 보강구조는, 측면 충돌시, 충돌하는 차량의 하부쪽에 사이드 실과 플로어판넬(20)이 취디되어 비교적 큰 하중이 집중되기 때문에, 대형 사고시 도어와 함께 측면부 차체가 실내로 침입하게 되는 문제점이 있었다.However, in the conventional reinforcement structure of the vehicle seal side, the side seal and the floor panel 20 are picked up on the lower side of the colliding vehicle at the time of side collision, so that a relatively large load is concentrated. There was a problem of intrusion.
본 발명의 목적은 상기와 같은 종래의 문제점을 보완하기 위해, 폐단면으로 형성되는 사이드 실내부에 별도의 보강판을 취부하여, 측면 충돌시 상기 보강판에 의해 도어에 가해지는 충격에너지를 흡수하고, 동시에 충격하중을 측면부 차체에 폭넓게 분산되도록 하는 자동차 사이드실의 보강구조를 제공하는데 있다.An object of the present invention is to install a separate reinforcement plate in the side interior portion formed as a closed cross-section, to solve the conventional problems as described above, to absorb the impact energy applied to the door by the reinforcement plate during side impact In addition, the present invention provides a reinforcement structure of an automobile side seal that allows the impact load to be widely distributed on the side body.
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 사이드 실 구조도 제2도에 도시되는 바와 같이, 절곡된 내측판넬(11)과 외측 판넬(12)이 소정의 공간을 두고 폐단면으로 결합되고, 상기 폐단면 내부에서 내측판넬(11)과 외측판넬(12) 사이에 사이드실 보강판(13)의 상단부와 하단부가 부착되며, 내측판넬(11)의 외측면이 플로어판넬(20)의 측단부에 연결되는 기술적 사상은 종래와 같다 하겠다. 단, 본 발명은 상기 폐단면 내부에 상단부와 하단부가 절교곡되어 플랜지가 형성된 보강판(15)이 사이드실 보강판(13)의 상부에 일측부가 취부되고, 타측부는 내측판넬(11)과 외측판넬(12) 사이에 취부됨을 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 surface with a predetermined space, and the inner panel 11 is formed inside the closed end surface. The upper and lower ends of the side seal reinforcing plate 13 are attached between the outer panel 12 and the outer panel 12, and the technical idea that the outer surface of the inner panel 11 is connected to the side end of the floor panel 20 is the same as in the related art. would. However, in the present invention, the upper end and the lower end are bent in the closed end surface so that the flange-shaped reinforcement plate 15 is mounted on one side of the upper side of the side seal reinforcement plate 13, and the other side of the inner panel 11 Mounting between the outer panel 12 is a basic feature of the technical configuration.
이와같이 구성되는 본 발명은, 측면 충돌시 외측판넬(12)에 의해 1차적으로 충격에너지를 흡수하고 충격하중이 분산되도록 하며, 2차적으로 사이드실 보강판(13)과 보강판(15)이 연계하여 실내쪽으로 작용하는 충격하중을 흡수하고 차체의 횡방향으로 폭넓게 하중을 분산시켜, 실내로 전달되는 충격을 완충시켜 주고, 도어 및 측부 차체가 실내로 침입되는 것을 효과적으로 억제시켜 준다.According to the present invention configured as described above, the side panel reinforcing plate 13 and the reinforcing plate 15 are secondarily connected to absorb the impact energy and disperse the impact load by the outer panel 12 during the side impact. It absorbs the impact load acting toward the interior and distributes the load widely in the transverse direction of the vehicle body, buffers the shock transmitted to the interior, and effectively prevents the door and the side vehicle body from entering the interior.
따라서, 이러한 본 발명은 차체의 변형이 억제되고, 충격이 효과적으로 완충되어, 측면 충돌시 승원의 안전성이 향상되도록 하는 효과가 있다.Therefore, the present invention has the effect that the deformation of the vehicle body is suppressed, the shock is effectively buffered, and the safety of the occupant is improved during side impact.
이상에서 살펴본 바와 같이, 본 발명은 폐단면으로 형성되는 사이드실의 내부에 보강판이 사이드실 보강판과 외측판넬과 내측판넬이 접하며 취부되어, 측면 충돌시 측부차체의 실내 침입을 억제하고 충격을 효과적으로 완충하도록 하는 매우 유용한 것이다.As described above, in the present invention, the reinforcing plate is mounted inside the side seal formed as a closed cross section so that the side seal reinforcing plate and the outer panel and the inner panel are in contact with each other. It's very useful to buffer.
