Abstract

PURPOSE: Reinforcing structure of a side sill in a vehicle is provided to effectively suppress an invasion of a side sill into a room of the vehicle when the vehicle is crashed. CONSTITUTION: Upper parts of an inner panel(11) and an outer panel(12) are installed an outside of a vehicle. The upper part of the inner panel(11) is inclined. A cross member(30) is installed by contacting its one end with the inclined portion. Shock energy is absorbed and shock load is dispersed by the outer panel(12) primarily. The shock load to be acted into a room of the vehicle is absorbed by the inner panel(11) with a side sill reinforcement(13). Thereby, the shock is buffered and an invasion of a door into the room is prevented effectively.

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 크로스멤버(CROSS MEMBER)가 사이드실(side sill)의 내측판넬의 일측부에 취부되어 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 is connected to the upper end to form an outer part of the roof, and a floor panel and a cross member, which form the bottom part of the vehicle, are formed in the side sills. It is mounted on 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)과 크로스멤버(30 : CROSS MEMBER)의 측단부에 내측판넬(11)의 외측면이 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 It is coupled, the upper end and the lower end of the side seal reinforcement plate (reinforcement) 13 is attached between the inner panel 11 and the outer panel 12 in the closed end surface, the floor panel 20 and the cross member 30: The outer side surface of the inner panel 11 is connected to the side end of the cross memory.

이와같이 구성되는 종래 자동차 실사이드의 보강구조는, 도어의 하단부가 외측판넬(12)의 상단부에 일정폭 수납되도록 되어, 측면충돌시 외측판넬(12)에 의해 1차적으로 충격에너지를 흡수하고, 충격하중을 사이드실보강판(13) 및 내측판넬(11)을 통해 플로어판넬(20)과 크로스멤버(30 : CROSS MEMBER)로 분산시키고, 측부 구조물인 도어가 실내로 침입되는 것을 억제하며, 사이드실보강판(13)이 2차적으로 충격에너지를 흡수하도록 하여, 측부 차체의 변형을 억제하고 실내의 승원이 보호되도록 되어 있다.The reinforcement structure of the conventional vehicle seal side configured as described above is such that the lower end of the door is accommodated in the upper end 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, The load is distributed to the floor panel 20 and the cross member 30 through the side seal reinforcement plate 13 and the inner panel 11, and the side structure door is prevented from entering the room, and the side seal The reinforcing plate 13 is secondary to absorb the impact energy, thereby suppressing deformation of the side vehicle body and protecting the occupant of the room.

그러나, 이러한 종래 자동차 사이드실의 보강구조는, 측면 충돌시, 충돌하는 차량의 범퍼 하부쪽에 사이드실과 플로어판넬(20)이 위치되어 비교적 큰 하중이 집중되기 때문에, 대형사고시 도어와 함께 측면부 차체가 실내로 침입하게 되는 문제점이 있었다.However, such a reinforcement structure of a conventional side wall of the vehicle has a side chamber and a floor panel 20 positioned at the lower side of the bumper of the colliding vehicle in a side collision, so that a relatively large load is concentrated. There was a problem to break into.

본 발명의 목적은 상기와 같은 종래의 문제점을 보완하기 위해, 내측판넬의 상단부 일측이 크로스멤버와 경사지게 취부되고, 상기 내측판넬과 외측판넬의 취부가 차량의 외측에서 이루어지도록 형성하여, 차량의 측면으로 충격이 가해지는 경우 충격에너지의 전달이 직선으로 이루어 지도록 형성되어, 충격하중을 측면부 차체에 폭넓게 분산되도록 하는 동시에, 차체의 변형량을 억제하도록 하는 자동차 사이드실의 보강구조를 제공하는 데 있다.An object of the present invention, in order to supplement the conventional problems as described above, one side of the upper end of the inner panel is mounted to be inclined with the cross member, the inner panel and the outer panel is formed to be made from the outside of the vehicle, the side of the vehicle The present invention provides a reinforcement structure of a vehicle side seal that is formed so that the impact energy is transmitted in a straight line when the impact is applied, so that the impact load is widely distributed on the side vehicle body and the amount of deformation of the vehicle body is suppressed.

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 사이드실의 보강 구조도 제2도에 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 외측면이 크로스멤버(30 : CROSS MEMBER)와 플로어판넬(20)의 측단부에 연결되는 기술적 사상은 종래와 같다 하겠다. 단, 본 발명은 상기 내측판넬(11)과 외측판넬(12)의 상단부가 차량의 외측에서 취부되고, 상기 내측판넬(11)의 외측 상단부가 경사지게 형성되며, 상기 경사부와 접하며 크로스멤버(30 : CROSS MEMBER)의 일측단부가 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 face with a predetermined space, and the inner side of the closed end face is shown in FIG. 2. An upper end and a lower end of the side seal reinforcing plate 13 are attached between the panel 11 and the outer panel 12, and the outer surface of the inner panel 11 is a cross member 30 and a cross panel 20. The technical idea that is connected to the side end of the same as conventional. However, in the present invention, the upper end portions of the inner panel 11 and the outer panel 12 are mounted on the outside of the vehicle, and the outer upper end portions of the inner panel 11 are formed to be inclined, and the cross members 30 are in contact with the inclined portion. : One end of CROSS MEMBER) is a basic feature of technical configuration.

이와같이 구성되는 본 발명은, 측면 충돌시 외측판넬(12)에 의해 1차적으로 충격에너지를 흡수하고 충격하중이 분산되도록 하며, 2차적으로 사이드실보강판(13)은 내측판넬(11)과 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 impact energy is primarily absorbed by the outer panel 12 during the side impact and the impact load is dispersed, and the side seal reinforcing plate 13 is secondly connected with the inner panel 11. Therefore, 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 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 인사이드보강판이 내측판넬의 내부면과 접하며 취부되어, 측면 충돌시 측부차체의 실내 침입을 억제하고 충격을 효과적으로 완충하도록 하는 매우 유용한 것이다.As described above, the present invention is mounted inside the side seal formed of the closed cross section in contact with the inner surface of the inner panel, it is very effective to suppress the invasion of the interior of the side body in the side impact and effectively cushion the impact It is useful.
