본 고안은 차량의 측면충격 대응을 위한 리어도어 강성보강구조에 관한 것으로, 더욱 상세하게는 차량의 리어도어에 가해지는 외부충격이 한곳에 집중되지 않고 적절히 분산 될 수 있도록 리어도어의 모퉁이에 가로질러 임팩트바를 설치한 것에 관한 것이다.The present invention relates to a rear door rigid reinforcement structure for responding to a side impact of a vehicle. More specifically, an impact bar is disposed across a corner of the rear door so that the external shock applied to the rear door of the vehicle can be properly distributed without being concentrated in one place. It is about installation.

일반적으로 보디는 사람이 타는 부분이 주체가 되도록 하고, 이것에 도어, 펜더 등의 외장부분이나 시트 등의 내장부분을 장착한 것으로서, 운전자 및 승차원에 필요한 안정성, 공간, 쾌적함 등의 요소를 갖추고 있어야 한다.In general, the body is the main part of the human ride, and is equipped with exterior parts such as doors and fenders, and interior parts such as seats, and has elements such as stability, space, and comfort necessary for the driver and the passengers. Should be

보디의 외부 구성부분에는 자동차의 외부에서 보이는 부분으로 승용차에서는 승차원의 승차석을 위시하여 엔진이나 트렁크 등에 필요한 공간과 주행중에 받은 외력에 대하여 필요한 강도를 확보하고 있는 부분이다.The outer part of the body is a part visible from the outside of the car. In the passenger car, the passenger seat is secured to the space required for the engine, the trunk, etc. and the external strength received while driving.

보디의 내부 구성부분은 자동차의 외부에서 보이지 않는 부분이지만, 외부구성 부분을 지지하여 보디 전체의 강도를 확보하고 있는 부분이며, 승용차에서는 외부 패널의 안쪽에 설치하는 각 패널이며 루프 패널 및 플로어 팬과 함께 접합되는 보디의 골격이 되는 부분이다.The internal parts of the body are invisible from the outside of the car, but they are the parts that secure the strength of the entire body by supporting the external parts.In the car, each panel is installed inside the external panel, and the roof panel and the floor fan It is a part which becomes a skeleton of the body joined together.

도어는 이너패널과 아웃터패널 어느 것이나 모두 강판제이며, 이너패널이 도어의 골조로 작용하여 도어의 강도를 유지하도록 되어 있으며, 이너패널에는 도어, 레귤레이터, 도어 록 기구 등을 장치하기 위한 단턱이나 구멍이 형성되어 있으며, 하중이 걸리는 부분에는 보강판이 장치되어 있으며, 안쪽에는 이너패널의 구멍을 덮기 위한 커버 및 도어 트림보드가 장치되어 있는데, 유사시 측면에서 가해지는 충격에 대응하기 위하여 리어도어 내부에 여러겹의 레인포스먼트(Reinforcement)를 설치하거나 리어도어의 이너패널의 양단에 연결부재가 용접되고 이 연결부재 사이에 수평방향으로 약간 경사지게 임팩트바(3)가 설치되어 있다.Both the inner panel and the outer panel are made of steel plate, and the inner panel acts as the frame of the door to maintain the strength of the door, and the inner panel has steps and holes for installing doors, regulators, and door lock mechanisms. It is formed, the load is applied to the reinforcement plate is equipped, the inside is equipped with a cover and a door trimboard for covering the hole of the inner panel, in order to cope with the impact from the side in case of emergency The reinforcement of the layer is provided, or the connecting member is welded to both ends of the inner panel of the rear door, and the impact bar 3 is installed to be slightly inclined in the horizontal direction between the connecting members.

그러나 예시도면 제1도 내지 제2도와 같이 측면 충격에 대한 강도를 확보하기 위한 임팩트바(3)가 설치된 종래의 구조는 측면으로 가해지는 충격력이 연결부재(11)에 집중되도록 되어있어 연결부재(11)와 차량의 횡방향으로 일직선상에 위치하는 보디의 사이드 아웃터 프레임(12)의 변형량이 커지게 되어 유사시 뒷자석 탑승객의 안전성이 확보되지 못하는 문제가 있었다.However, in the conventional structure in which the impact bar 3 is installed to secure the strength against side impact, as illustrated in FIGS. 1 to 2, the impact force applied to the side is concentrated on the connection member 11. 11) and the amount of deformation of the side outer frame 12 of the body located in a straight line in the transverse direction of the vehicle is large, there is a problem that the safety of the rear passengers in case of emergency is not secured.

따라서 본 고안은 이와같은 문제점을 해결하기 위하여 안출한 것으로, 리어도어의 이너패널에 설치되는 임팩트바와 연결부재에 가해지는 측면충격을 적절히 분산할 수 있도록 리어도어의 록킹부와 사이드 시일부를 가로지르는 서브 임팩트바를 설치하고 임팩트바의 일단이 서브 임팩트바의 일단과 결합하여 임픽트바에 가해지는 충격력이 서브 임팩트바에 전달되도록 할 수 있는 측면충격 대응을 위한 리어도어 강성보강구조를 제공하는 데 본 고안의 목적이 있다.Therefore, the present invention has been devised to solve such a problem, and the sub bar that intersects the locking portion and the side seal portion of the rear door so as to properly distribute the side impact applied to the impact bar and the connection member installed on the inner panel of the rear door. The purpose of the present invention is to provide a rear door rigid reinforcement structure for lateral impact response in which an impact bar is installed and one end of the impact bar is combined with one end of the sub impact bar so that the impact force applied to the impact bar can be transmitted to the sub impact bar. have.

이와같은 목적을 실현하기 위한 본 고안의 구성과 작용효과를 첨부된 예시도면과 함께 상세히 설명하면 다음과 같다.The construction and effect of the present invention for realizing such an object will be described in detail with the accompanying drawings.

본 고안은 리어도어(1)의 이너패널(2)에 임팩트바(3)가 설치된 차량의 리어도어 구조에 있어서, 리어도어(1)의 록킹부(4)와 도어측 사이드 시일부(5)에 각각 연결부재(6)를 설치하여, 상기 연결부재(6) 사이에 서브 임팩트바(7)를 설치하고, 임팩트바(3)와 서브 임팩트바(7)가 교차되는 부분에 연결 브라켓(8)을 설치하여 임팩트바(3)의 선단부를 서브 임팩트바(7)에 고정한 구조로 되어 있다.According to the present invention, in the rear door structure of a vehicle in which the impact bar 3 is installed on the inner panel 2 of the rear door 1, the locking part 4 and the door side side seal part 5 of the rear door 1 are provided. Each connecting member 6 is installed on the connecting member 6, and the sub-impact bar 7 is installed between the connecting members 6, and the connecting bracket 8 is provided at the portion where the impact bar 3 and the sub-impact bar 7 cross each other. ) And a tip end portion of the impact bar 3 is fixed to the sub-impact bar 7.

예시도면 제 3도 내지 제 4도는 본 고안에 따른 실시예를 보인 것으로, 임팩트바(3)는 차량의 측면에 가해지는 충격에 대응할 수 있도록 리어도어(1)의 이너패널(2)에 수평방향으로 설치되어 있으며, 임팩트바(3)에 가해지는 외부의 충격이 임픽트바(3)의 연결부재(11)에 집중되지 않도록 보디의 사이드 아웃터 프레임(12)과 근접한 임팩트바(3)의 일단은 리어도어(1)의 록킹부(4)와 사이드 시일부(5) 사이에 설치되어지는 서브 임팩트바(7)의 일단에 고정되어 있다. 서브 임팩트바(7)의 연결부재(6)는 리어도어(1)의 이너패널(2)의 록킹부(4)와 사이드 시일부(5)에 용접으로 결합되는데 록킹부(4)는 보디의 록킹부와 결합되어 잠금작용을 하기 때문에 록킹부 주변은 보강재가 내재되어 있어 다른 부분보다 강성을 유지하고 있으며, 사이드 시일부(5)도 바디와 프레임이 일체주조로 형성된 경우 보디의 하부를 지탱해야 하므로 다른부분보다 강성을 유지하고 있어 서브 임팩트바(7)는 충격력의 침입량을 최소화할 수 있다.3 to 4 show an embodiment according to the present invention, the impact bar (3) is horizontal to the inner panel (2) of the rear door (1) to respond to the impact applied to the side of the vehicle One end of the impact bar 3 adjacent to the side outer frame 12 of the body so that the external impact applied to the impact bar 3 is not concentrated on the connecting member 11 of the impact bar 3. Is fixed to one end of the sub-impact bar 7 provided between the locking portion 4 and the side seal portion 5 of the rear door 1. The connecting member 6 of the sub-impact bar 7 is welded to the locking portion 4 and the side seal portion 5 of the inner panel 2 of the rear door 1 by welding. Since the locking part is combined with the locking part, the reinforcement is embedded around the locking part to maintain rigidity, and the side seal part 5 must also support the lower part of the body when the body and the frame are formed by integral casting. Therefore, since the rigidity is maintained more than other parts, the sub-impact bar 7 can minimize the intrusion amount of the impact force.

여기서 임팩트바(3)와 서브 임팩트바(7)의 연결부는 연결브라켓(8)이 설치되어 임팩트바(3)의 선단부와 서브 임팩트바(7)의 일단에 용접되어 견고하게 고정 설치된다.Here, the connection portion 8 of the impact bar 3 and the sub impact bar 7 is provided with a connection bracket 8 and is firmly fixed to the front end of the impact bar 3 and one end of the sub impact bar 7 by welding.

즉 본 고안의 측면충격에 대한 대응은 임팩트바(3)에 걸리는 충격력을 연결브라켓(8), 서브 임팩트바(7), 연결부재(6)에 각각 전달하여 보디의 변형량을 최소화한다.That is, in response to the side impact of the present invention, the impact force applied to the impact bar 3 is transmitted to the connection bracket 8, the sub impact bar 7, and the connection member 6, respectively, to minimize the amount of deformation of the body.

따라서 본 고안에 따르면 리어도어의 측면충격에 대한 보디의 변형을 최소화하여 승객의 안전성을 향상시킬 수 있는 효과를 가져올 수 있다.Therefore, according to the present invention can minimize the deformation of the body to the side impact of the rear door can bring the effect of improving the safety of the passengers.
