본 발명은 자동차 측면 하부의 차체구조에 관한 것으로서, 특히 승원의 안정성을 향상시켜 주기 위해, 차량의 측부 충돌시, 도어(door)와 사이드실(side sill)이 실내로 침입되는 것을 효과적으로 억제하도록 하는 자동차 도어와 사이드실의 보강구조에 관한 것이다.The present invention relates to the body structure of the lower side of the vehicle, in particular to improve the stability of the occupant, in order to effectively suppress the entry of the door (door) and side sill into the room during the side collision of the vehicle It relates to a reinforcement structure of a car door and a side seal.

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 전면부를 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 the front part of the vehicle, are connected to the lower end of the pillars.

여기에서, 종래 자동차 도어와 사이드실의 설치구조는 제1도에 도시되는 바와 같이, 절곡된 내측판넬(12:INNER PANEL)과 외측판넬(11:OUTER PANEL)이 소정의 공간을 두고 폐단면으로 결합되고, 상기 내측판넬(12:INNER PANEL)의 외측과 접하도록 절곡된 아웃사이드프레임(25)의 상단부와 하단부가 인사이드프레임(22)에 부착되며, 상기 인사이드프레임(22)의 외측면에 플로판넬(30)의 일측단부가 연결되어 있다.Here, in the conventional installation structure of the car door and the side seal, as shown in FIG. 1, the inner panel 12 (inner panel) 12 and the outer panel 11 (outer panel 11) are bent to a closed section with a predetermined space. The upper and lower ends of the outer frame 25, which are coupled to each other and bent to contact the outer side of the inner panel 12, are attached to the inner frame 22 and flow on the outer surface of the inner frame 22. One end of the panel 30 is connected.

이와 같이 구성되는 종래 자동차 도어와 사이드실의 설치구조는, 도어(10)의 하단부가 아웃사이드프레임(25)의 상단부에 일정폭 수납되도록 되어, 측면충돌시 아웃사이드프레임(25)에 의해 1차적으로 충격에너지를 흡수하고, 충격하중을 인사이드프레임(22)을 통해 플로어판넬(30)로 분산시키고, 측부 구조물인 도어가 실내로 침입되는 것을 억제 흡수하도록 하여, 측부 차체의 변형을 억제하고 실내의 승원이 보호되도록 되어 있다.The installation structure of the conventional vehicle door and side seals configured as described above is such that the lower end portion of the door 10 is accommodated in a predetermined width portion at the upper end portion of the outer frame 25, and is primarily provided by the outer frame 25 during side impact. Absorbs the impact energy, distributes the impact load to the floor panel 30 through the inside frame 22, and suppresses the entry of the door, which is a side structure, into the room, thereby suppressing deformation of the side vehicle body and The occupants are to be protected.

그러나 이러한 종래 자동차 도어와 사이드실의 설치구조는, 측면 충돌시, 충돌하는 도어(10)의 내부와 사이드실(20)의 내부에 아무런 충격흡수 구조를 갖고 있지 못하여, 대형사고시 도어와 함께 측면부 차체가 실내로 침입하게 되는 문제점이 있었다.However, such a conventional vehicle door and side seal installation structure has no shock absorbing structure in the interior of the side door 20 and the collision of the door 10 in the event of a side collision, the side body along with the door in the event of a large accident There was a problem that is to break into the room.

본 발명의 목적은 상기와 같은 종래의 문제점을 보완하기 위해, 폐단면으로 형성되는 도어의 내부와 사이드실의 내부에 보강판(REINFORCEMENT)를 장착하여, 측면 충돌시 상기 사이드실 내부에서 충격에너지를 흡수하는 동시에 충격하중에 의하여 도어가 차실로 유입되는 것을 억제하도록 하는 자동차 도어와 사이드실의 보강구조를 제공하는 데 있다.An object of the present invention is to reinforce the conventional problem as described above, by mounting a reinforcement plate (REINFORCEMENT) in the interior of the side chamber and the interior of the door is formed in a closed cross-section, the impact energy inside the side chamber during side impact It is to provide a reinforcement structure of the car door and the side seal to absorb and at the same time to prevent the door from entering the compartment by the impact load.

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 도어와 사이드실의 보강구조도 제2도에 도시되는 바와 같이, 하단부가 절곡된 도어(10)의 내측판넬(12:INNER PANEL)과 외측판넬(11:OUTER PANER)이 소정의 공간을 두고 폐단면으로 결합되고, 상기 내측판넬(12:INNER PANEL)의 외측과 접하도록 절곡된 아웃사이드프레임(25)의 상단부와 하단부가 인사이드프레임(22)에 부착되며, 상기 인사이드프레임(22)의 외측면에 플로어판넬(30)의 일측단부가 연결되는 것에 있어서, 상기 도어(10)의 내측판넬(12:INNER PANEL) 내측면에 보강판(40)이 취부되고, 상기 내측판넬(12)의 외측과 접하는 인사이드프레임(22)과 아웃사이드프레임(25)의 내측면에 보강판(40)이 취부되며, 상기 아웃사이더프레임(25)의 외측면에 일측단부가 플로어판넬(30)에 취부된 보강판(40)이 취부됨을 그 기술적 구성상의 기본 특징으로 한다.As shown in FIG. 2, the reinforcing structure of the automobile door and the side seal of the present invention includes an inner panel 12 and an outer panel 11 of the door 10 having a lower end bent. The upper and lower ends of the outer frame 25, which are coupled to the closed end surface with a space and bent to contact the outer side of the inner panel 12, are attached to the inner frame 22, and the inner frame 22. In one side end of the floor panel 30 is connected to the outer side of the), the reinforcing plate 40 is mounted on the inner side of the inner panel 12 (INNER PANEL) of the door 10, the inner panel 12 Reinforcing plate 40 is mounted on the inner side of the outer frame 22 and the outer frame 25 in contact with the outer side of the outer side, one side end on the outer surface of the outer frame 25 to the floor panel 30 It is a basic feature of the technical configuration that the mounting reinforcement plate 40 is mounted.
