Description
본 발명은 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.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a body structure of a lower side of an automobile, and in particular, in order to improve the safety of the occupant, in the case of a side collision of the vehicle, the side sill is effectively prevented from invading the inside of the vehicle. It relates to a reinforcement structure.
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 사이드실구조는 도 1에 도시되는 바와 같이, 상단부가 다단으로 절곡되어 형성된 외측판넬(12)의 일측면에 소정의 공간을 두고 폐단면으로 내측판넬(11)이 취부되고, 상기 내측판넬(11)의 하단부 일측면에는 차량의 저면을 형성하는 플로어판넬(20)의 일측단부가 취부되어 있다.Here, in the conventional vehicle side seal structure, as shown in Figure 1, the inner panel 11 is mounted in a closed end surface with a predetermined space on one side of the outer panel 12 formed by bending the upper end in multiple stages, One end of the floor panel 20 that forms the bottom of the vehicle is mounted on one side of the lower end of the inner panel 11.
이와 같이 구성되는 종래 자동차 사이드실구조는, 도어(40)의 하단부가 외측판넬(12)의 상단부에 일정폭 수납되도록 되어, 측면충돌시 외측판넬(12)에 의해 1차적으로 충격에너지를 흡수하고, 충격하중을 내측판넬(11)을 통해 플로어판넬(20)로 분산시키고, 측부 구조물인 도어(40)가 실내로 침입되는 것을 억제 흡수하도록 하여, 측부 차체의 변형을 억제하고 실내의 승원이 보호되도록 되어 있다.In the conventional vehicle side seal structure configured as described above, the lower end portion of the door 40 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. In addition, the impact load is distributed to the floor panel 20 through the inner panel 11, and the door 40, which is a side structure, is absorbed and absorbed into the room, thereby suppressing deformation of the side vehicle body and protecting the occupant of the room. It is supposed to be.
그러나, 이러한 종래 자동차 사이드실구조는, 측면 충돌시, 충돌하는 차량의 범퍼 하부쪽에 사이드실(10)과 플로어판넬(20)이 위치되어 비교적 큰 하중이 집중되기 때문에, 대형사고시 도어(40)와 함께 측면부 차체가 실내로 침입하게 되어 차실에 탑승한 승원이 부상을 입게 되는 문제점이 있었다.However, such a conventional vehicle side seal structure has a side chamber 10 and a floor panel 20 positioned under the bumper of the colliding vehicle at the time of side collision, so that a relatively large load is concentrated. In addition, the side of the vehicle was intruded into the room there was a problem that the occupant in the cabin is injured.
본 발명의 목적은 상기와 같은 종래의 문제점을 보완하기 위해, 다단으로 절곡 형성된 외측판넬과 내측판넬이 소정의 공간을 두고 폐단면으로 결합되고, 상기 폐단면의 내부에는 상단부와 하단부가 절곡 형성된 내측보강판이 플랜지되며, 상기 내측판넬의 외측면에는 일측단부가 절곡 형성된 플로어판넬을 연결하여, 측면 충돌시 사이드실 내부에서 충격에너지를 흡수하는 동시에 충격하중에 의하여 도어가 차실로 유입되는 것을 억제하도록 하는 자동차 사이드실의 보강구조를 제공하는데 있다.An object of the present invention, in order to supplement the conventional problems as described above, the outer panel and the inner panel formed in multiple stages are combined into a closed section with a predetermined space, the inside of the closed end surface is formed with the upper end and the lower end bent The reinforcing plate is flanged, and a floor panel having one side end bent is connected to the outer surface of the inner panel to absorb the impact energy inside the side chamber during side impact and to prevent the door from entering the vehicle compartment by the impact load. The present invention provides a reinforcement structure for an automobile side seal.

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 자동차의 사이드실 보강구조는 도 2에 도시하고 있는 바와 같이 다단으로 절곡 형성된 외측판넬(12)와 내측판넬(11)이 소정의 공간을 두고 폐단면으로 결합되고, 상기 폐단면의 내부에는 상단부와 하단부가 절곡 형성된 내측보강판(13)이 플랜지되며, 상기 내측판넬(11)의 외측면에는 일측단부가 절곡 형성된 플로어판넬(20)이 연결됨을 그 기술적 구성상의 기본 특징으로 한다.In the side seal reinforcement structure of the vehicle of the present invention, as shown in FIG. 2, the outer panel 12 and the inner panel 11, which are bent in multiple stages, are coupled to a closed cross section with a predetermined space, and the inside of the closed cross section. The inner reinforcing plate 13 is bent in the upper end and the lower end is bent, the outer surface of the inner panel 11 is connected to the floor panel 20 is formed in one side end is a basic feature of the technical configuration.
이와 같이 구성되는 본 발명의 자동차의 사이드실 보강구조는, 측면 충돌시 외측판넬(12)과 내측보강판(13) 사이에 형성된 폐단면에서 1차적으로 충격에너지를 흡수하고, 2차적으로 내측보강판(13)과 내측판넬(11)에 형성된 폐단면에서 충격하중을 흡수하며, 3차적으로 내측판넬(11)을 통해 플로어판넬(20)로 충격에너지를 분산시켜, 측부 구조물이 파손되어 차실로 침입되는 것을 억제하게 된다.The side seal reinforcement structure of the vehicle of the present invention configured as described above primarily absorbs the impact energy at the closed end surface formed between the outer panel 12 and the inner reinforcement plate 13 during side impact, and secondly reinforces the inner side. The shock load is absorbed from the closed end surfaces formed on the plate 13 and the inner panel 11, and the impact energy is distributed to the floor panel 20 through the inner panel 11 in a third manner, so that the side structure is damaged and thus into the compartment. Intrusion is suppressed.
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.
