Description
본 고안은 자동차 측면 하부에 형성되는 사이드실구조에 관한 것으로서, 특히 승원의 안전성을 향상시켜 차량의 측부 충돌시에도 도어(door)와 플로어판넬이 실내로 침입되는 것을 효과적으로 억제하도록 하는 자동차의 측면하부 보강구조에 관한 것이다.The present invention relates to a side seal structure formed in the lower side of the vehicle, and in particular, to improve the safety of the occupants in the side of the vehicle to effectively prevent the entry of the door (door) and floor panels into the room even during side impact of the vehicle It relates to a reinforcement structure.
일반적으로 자동차의 측면부 차체구조는 제 1 도에 도시하고 있는 바와 같이, 전면기둥(1:front pillar)과 중심기둥(2:center pillar)및 후면기둥(3:rear pillar) 사이에 개구부가 형성되어, 상기 개구부에 도어(4)가 개폐 가능하게 설치되고, 상기 기둥들 상단부에 지붕의 외측부를 형성하는 루프레일(5:roof rail)이 연결되며 상기 기둥들 하단부에 차량의 저면부를 형성하는 플로어판넬(floor panel)과 사이드실(10:side sill)이 연결되어 있다.In general, as shown in FIG. 1, the side body structure of an automobile has an opening formed between a front pillar (1) and a center pillar (2) and a rear pillar (3). A floor panel is provided to open and close the door 4 in the opening, and a roof rail 5 is connected to an upper end of the pillars to form an outer portion of the roof, and a bottom portion of the vehicle is formed at the lower ends of the pillars. The floor panel and the side sill are connected.
여기에서, 종래 자동차의 측면하부 보강구조는 제 2 도에 도시하는 바와 같이, 다단으로 절곡되어 형성된 내측판넬(11:INNER PANEL)과 외측판넬(12:OPUTER PANEL)이 소정의 공간을 두고 폐단면으로 결합되고, 상기 폐단면의 내부에는 상단부와 하단부가 절곡되어 형성된 내측보강판(15)이 플랜지며, 상기 내측판넬(11)의 외측면에는 저면에 프레임(30)의 일측단부가 취부되어 있는 플로어판넬(20)이 연결되어 있다.Here, the side lower reinforcement structure of the conventional vehicle, as shown in Figure 2, the inner panel 11 and the inner panel (11: OPUTER PANEL) formed by bending in multiple stages closed section with a predetermined space The inner reinforcing plate 15 is formed by bending the upper end and the lower end inside the closed end surface, and the one side end of the frame 30 is mounted on the bottom of the inner side of the inner panel 11. The floor panel 20 is connected.
이와같이 구성되는 종래 자동차의 측면하부 보강구조는, 측면충돌시 외측판넬(12)과 내측보강판(15) 사이에 형성된 폐단면에서 1차적으로 충격에너지를 흡수하고, 2차적으로 내측보강판(15)과 내측판넬(11)에 형성된 폐단면에서 충격하중을 흡수하며, 3차적으로 내측판넬(11)을 통해 플로어판넬(20)의 저면에 형성된 폐단면으로 충격에너지를 흡수 및 분산시켜, 측부 구조물이 파손되어 차실로 침입되는 것을 억제하여 실내의 승원이 보호되도록 되어 있다.The lower side reinforcement structure of the conventional vehicle configured as described above primarily absorbs the impact energy at the closed end surface formed between the outer panel 12 and the inner reinforcing plate 15 during side impact, and secondly the inner reinforcing plate 15. ) And absorbs impact load from the closed end surface formed on the inner panel 11, and absorbs and disperses the impact energy to the closed end surface formed on the bottom surface of the floor panel 20 through the inner panel 11, and thus the side structure. This damage is prevented from entering the vehicle compartment, and the occupants of the room are protected.
그러나, 이러한 종래 자동차의 측면하부 보강구조는, 차량의 측면으로 충돌사고가 발생하여 사이드실(10)을 형성하는 외측판넬(12)이 내측으로 밀려드는 경우, 사이드실(10)의 내부에 취부된 내측보강판(15)이 충격에너지를 흡수하지 못하고 쉽게 변형이 발생하게 됨은 물론, 내측판넬(11)에 전달되는 충격에너지가 플로어판넬(20)로 집중됨으로서, 상기 플로어판넬(20)이 실내로 침입하게 되어 차내에 탑승한 승원이 부상을 입게 되는 등의 문제점이 있었다.However, such a side lower reinforcement structure of a conventional vehicle is mounted inside the side chamber 10 when a collision accident occurs on the side of the vehicle and the outer panel 12 forming the side chamber 10 is pushed inward. As the inner reinforcing plate 15 does not absorb the impact energy and easily deforms, the impact energy transmitted to the inner panel 11 is concentrated on the floor panel 20, so that the floor panel 20 is indoors. There was a problem such that the crew injured in the car was injured.
본 고안의 목적은 상기와 같은 종래의 문제점을 보완하기 위해, 사이드실의 내부에 설치되는 내측보강판을 돌출되게 형성하고, 사이드실을 형성하는 내측판넬과 플로어판넬에 지지보강판이 폐단면을 형성하며 취부되어, 측면 충돌시 사이드실 내부에서 충격에너지를 흡수하는 동시에 충격하중에 의하여 차체가 차실로 유입되는 것을 억제하도록 하는 자동차의 측면하부 보강구조를 제공하는데 있다.The object of the present invention is to complement the conventional problems as described above, to form a protruding inner reinforcement plate installed in the interior of the side seal, the supporting reinforcement plate formed on the inner panel and the floor panel forming the side seal closed section And it is mounted, to provide a side lower reinforcement structure of the vehicle to absorb the impact energy inside the side chamber during side impact and at the same time to suppress the vehicle body from entering the vehicle by the impact load.

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 자동차의 측면하부 보강구조도 제 3 도에 도시하는 바와 같이, 다단으로 절곡되어 형성된 내측판넬(11:INNER PANEL)과 외측판넬(12:OPUTER PANEL)이 소정의 공간을 두고 폐단면으로 결합되고, 상기 폐단면의 내부에는 상단부와 하단부가 절곡되어 형성된 내측보강판(15)이 플랜지며, 상기 내측판넬(11)의 외측면에는 일측단부가 절곡되어 형성된 플로어판넬(20)이 연결되어 지는 것은 종래와 같다. 단 본 고안은 상기 내측판넬(11)과 플로어판넬(20)에 지지보강판(40)이 취부되어 폐단면을 형성하고, 상기 내측판넬(11)과 외측판넬(12) 사이에 취부되는 내측보강판(15)은 돌출되게 형성됨을 그 기술적 구성상의 기본 특징으로 한다.As shown in FIG. 3, the inner side panel 11 (inner panel) and the outer panel 12 (OPUTER PANEL) formed by bending in multiple stages have a predetermined space and are closed to the end surface of the automobile according to the present invention. The inner reinforcing plate 15 formed by bending the upper end and the lower end is coupled to the inside of the closed end surface, and the floor panel 20 formed by bending one side end is connected to the outer side of the inner panel 11. Losing is the same as before. However, in the present invention, the support reinforcing plate 40 is attached to the inner panel 11 and the floor panel 20 to form a closed cross section, and the inner reinforcing member is mounted between the inner panel 11 and the outer panel 12. The plate 15 is formed to protrude as a basic feature of the technical configuration.
이와같이 구성되는 본 고안은, 측면 충돌시 외측판넬(12)이 실내쪽으로 작용하여 충격하중을 1차적으로 흡수하고, 2차적으로 내측보강판(15)의 돌출부에 외측판넬(12)의 내측면이 접하여 충격에너지를 흡수하며 3차적으로 내측보강판(15)이 변형되며 내측판넬(11)로 전달된 충격에너지는 경사면을 따라 분산되며, 내측판넬(11)과 플로어판넬(20)에 지지보강판(40)이 취부되어 형성된 폐단면 내에서 충격에너지를 흡수함과 동시에 플로어판넬(20)로 폭넓게 하중을 분산시켜, 실내로 전달되는 충격을 완충시켜 측부 차체가 실내로 침입되는 것을 효과적으로 억제시켜 준다.The present invention configured as described above, the outer panel 12 acts toward the interior when the side impacts, primarily absorbing the impact load, and secondly the inner surface of the outer panel 12 to the protrusion of the inner reinforcing plate 15 In contact with the absorbing shock energy and the third inner reinforcement plate 15 is deformed, the impact energy delivered to the inner panel 11 is distributed along the inclined surface, the support reinforcing plate on the inner panel 11 and the floor panel 20 While absorbing the impact energy in the closed end surface formed by mounting (40), the load is distributed to the floor panel 20 widely, buffering the shock transmitted to the room effectively prevents the side car body from entering the room. .
따라서, 이러한 본 고안은 차량의 사이드부의 강성이 향상되어, 차체의 변형이 억제되고, 충격이 효과적으로 완충되어, 측면 충돌시 승원의 안전성이 향상되도록 하는 효과가 있다.Therefore, the present invention has the effect of improving the rigidity of the side portion of the vehicle, suppressing the deformation of the vehicle body, effectively cushioning the impact, and improving the safety of the occupant during side impact.
이상에서 살펴본 바와 같이, 본 고안은 사이드실의 내부에 설치되는 내측보강판을 돌출되게 형성하고, 사이드실을 형성하는 내측판넬과 플로어판넬에 지지보강판이 폐단면을 형성하며 취부되어, 측면 충돌시 사이드실 내부에서 충격에너지를 흡수하는 동시에 충격하중에 의하여 차체가 차실로 유입되는 것을 억제하도록 하는 매우 유용한 고안인 것이다.As described above, the present invention is formed so as to protrude the inner reinforcing plate installed in the interior of the side seal, the supporting reinforcement plate is formed in the inner panel and the floor panel forming the side seal forming a closed cross-section, when the side impact It is a very useful design to absorb the impact energy inside the side chamber and to prevent the vehicle body from entering the vehicle compartment by the impact load.
