본 발명은 자동차 도어와 리어펜더(rear fender)부의 구조에 관한 것으로서, 특히 후부의 측면도어와 리어펜더부의 구조를 변경하여, 측면 충돌시 충격하중을 초기에 효과적으로 분산시키도록 하는 자동차 도어부의 보강구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of an automobile door and a rear fender portion, and in particular, a reinforcement structure of an automobile door portion to change the structures of the rear side door and the rear fender portion so as to effectively distribute the impact load at the time of side impact. It is about.

일반적으로 자동차 차체의 측부구조는, 제1도에 도시되는 바와 같이, 차량의 측부를 형성하는 리어펜더(10)의 상부가 후면기둥(20)을 통해 연장되어 지붕(30)의 측부에 연결되고, 리어펜더(10)의 하부 선단에 사이드실(side sill)(40)이 연장되게 연결되며, 지붕(30)과 사이드실(40) 사이가 개구되어, 임팩트바(impact bar)(50)가 장착되는 도어(60)가 개구부에 개폐 가능하게 설치되어 있다.In general, the side structure of the vehicle body, as shown in Figure 1, the upper portion of the rear fender 10 forming the side of the vehicle extends through the rear pillar 20 is connected to the side of the roof 30 The side sill 40 is extended to the lower end of the rear fender 10, and an opening between the roof 30 and the side sill 40 is opened, so that an impact bar 50 is formed. The door 60 to be mounted is provided in the opening portion so as to be openable and openable.

여기에서, 리어펜더(10)부는 제2도에 도시되는 바와 같이, 도어(60)의 후면부 외각선을 따라 사이드프레임(11)이 다단의 절곡면으로 형성되어 도어(60)의 가이드라인(guide line)을 형성하며, 사이드프레임(11) 안쪽에 쿼터판넬(12)의 일단부가 연결되고, 쿼터판넬(12)과 사이드프레임(11) 사이에 휠아크판넬(wheel arch panel)(13)이 사이드프레임(11)과 폐단면으로 결합되어 있다.Here, the rear fender 10, as shown in FIG. 2, the side frame 11 is formed of a multi-stage bending surface along the outer periphery of the rear portion of the door 60, the guide line of the door 60 one side of the quarter panel 12 is connected to the inside of the side frame 11, and a wheel arch panel 13 is disposed between the quarter panel 12 and the side frame 11. It is coupled to the frame 11 and the closed section.

한편, 도어(60)는 다단으로 절곡 되는 내측판넬(61)과 외측판넬(62)이 일정 공간을 두고 외곽부가 결합되고, 상기 공간 내부에서 내측판넬(61)의 절곡부에 정션(junction)(51)이 취부되어, 측면충돌시 충격을 흡수하도록 하는 임팩트바(50)의 양단부가 정션(51)에 취부되어 있다.On the other hand, the door 60 is coupled to the outer panel 61 and the outer panel 62 is bent in multiple stages with a predetermined space, the junction (junction) in the bent portion of the inner panel 61 in the space ( 51 is mounted, and both ends of the impact bar 50 are mounted to the junction 51 so as to absorb the impact during side impact.

이와같이 구성되는 종래 자동차 차체의 측부구조는, 도어(60)가 사이드프레임(11)의 선단 가이드라인과 사이드실(40) 상부를 따라 측부 개구부에 닫히게 되며, 이때 도어(60)의 내측판넬(61)은 상기 개구부로 수납되고, 도어(60)의 외곽부가 개구부의 가이드라인부에 기밀하게 밀착되도록 되어 있다.In the side structure of the conventional vehicle body configured as described above, the door 60 is closed at the side opening along the tip guide line of the side frame 11 and the upper side chamber 40, and the inner panel 61 of the door 60 is closed. ) Is accommodated in the opening, and the outer portion of the door 60 is hermetically adhered to the guide line of the opening.

그러나, 이러한 종래 자동차 차체의 측부구조는, 도어(60) 내부에 장착되는 임팩트바(50)와 사이드프레임(11)부가 중첩되지 않는 구조이기 때문에, 차량의 측면 충돌시 도어(60)에 충격하중이 집중되는 경우, 도어(60)의 외곽부와 사이드프레임(11)에 의해서만 지지되므르, 사이드프레임(11)과 도어(60)가 비교적 쉽게 실내쪽으로 침입되는 문제점이 있었다.However, since the side structure of the conventional vehicle body has a structure in which the impact bar 50 mounted inside the door 60 and the side frame 11 do not overlap, the impact load is applied to the door 60 during the side collision of the vehicle. When this concentration is concentrated, only the outer part of the door 60 and the side frame 11 are supported, so that the side frame 11 and the door 60 are relatively easily invaded into the interior.

본 발명의 목적은 상기와 같은 종래의 문제점을 보완하기 위해, 임팩트바가 지지되는 정션이 내측판넬의 최외곽부까지 연장되고 브라켓에 의해 정션 내측부가 지지되며, 상기 정션과 중첩되도록 사이드프레임과 휠아크판넬 사이에 보강판이 결합되도록하여, 측부의 강성이 향상되도록 하므로, 측면부 충돌시 차체의 변형과 실내 침입을 효과적으로 억제하도록하는 자동차 도어부의 보강구조를 제공하는 데 있다.An object of the present invention, in order to supplement the conventional problems as described above, the junction where the impact bar is supported extends to the outermost part of the inner panel and the junction inner part is supported by the bracket, so as to overlap the side frame and the wheel arc Since the reinforcing plate is coupled between the panels to improve the rigidity of the side, to provide a reinforcement structure of the vehicle door portion to effectively suppress the deformation of the vehicle body and the intrusion into the room during side impact.

이하 첨부된 도면에 의하여 본 발명의 기술적 사상을 상세히 설명하면 다음과 같다.Hereinafter, the technical spirit of the present invention will be described in detail with reference to the accompanying drawings.

본 발명의 자동차 차체도 제1도와 제3도에 도시되는 바와 같이, 개구부를 형성하는 사이드프레임(11)이 다단의 절곡면으로 형성되어 도어(60)의 가이드라인(guide line)을 형성하며, 사이드프레임(11) 안쪽으로 쿼터판넬(12)이 연결되고, 사이드프레임(11)과 쿼타판넬(12) 사이에 휠아크판넬(13)이 폐단면으로 결합되며, 다단으로 절곡되는 내측판넬(61)과 외측판넬(62)에 소정 공간을 두고 결합되어 상기 개구부에 개폐되는 도어의 공간 내부에 임팩트바(50)의 양단부가 정션(51)에 의해 취부되는 것은 종래와 같다. 단, 본 발명은 임팩트바(50)가 지지되는 정션(51)의 일단부가 연장되어 외측판넬(62)이 결합되는 내측판넬(61)의 최외곽부까지 연장되고, 정션(51)의 타단부 내측이 내측판넬(61)에 취부되는 절곡된 브라켓(52)에 지지되며, 정션(51) 및 사이드프레임(11)의 전체가 중첩되도록 사이드프레임(11)과 휠아크판넬(13) 사이에 보강판(14)이 폐단면으로 결합됨을 그 기술적 구성상의 기본 특징으로 한다.As shown in FIG. 1 and FIG. 3 of the vehicle body of the present invention, the side frame 11 forming the opening is formed in a multi-stage bending surface to form a guide line of the door 60. Quarter panel 12 is connected to the side frame 11, the wheel panel 13 is coupled between the side frame 11 and the quarter panel 12 in a closed section, the inner panel 61 is bent in multiple stages. ) And both ends of the impact bar 50 are mounted by the junction 51 in the space of the door coupled to a predetermined space in the outer panel 62 and opened and closed in the opening. However, in the present invention, one end of the junction 51 on which the impact bar 50 is supported extends to the outermost part of the inner panel 61 to which the outer panel 62 is coupled, and the other end of the junction 51. The inner side is supported by the bent bracket 52 mounted on the inner panel 61, and reinforced between the side frame 11 and the wheel arc panel 13 so that the entirety of the junction 51 and the side frame 11 overlap. It is a basic feature of the technical configuration that the plate 14 is coupled to the closed section.

한편, 도어는 내측판넬(61)과 외측판넬(62)의 후단부 사이에 정션(51)이 연장되어 일체로 결합되고, 일체로 결합된 도어의 후단부가 안쪽으로 절곡 연장되어 사이드프레임(11)의 외측부를 덮도록 형성된다.Meanwhile, the door has a junction 51 extending between the inner end of the inner panel 61 and the outer end of the outer panel 62 to be integrally coupled, and the rear end of the integrally coupled door is bent and extended inward to the side frame 11. It is formed to cover the outer portion of the.

이와같이 구성되는 본 발명은, 다단으로 절곡된 내측판넬(61)의 측면부와 사이드프레임(11)의 절곡면에 중첩되게 밀착되고, 임팩트바(50)의 정션(51)이 내측판넬(61)과 사이드프레임(11) 및 보강판(14)에 중첩되게 위치되며, 브라켓(52)에 의해 임팩트바(50)와 정션(51)이 지지되어, 차량의 측면부 충돌로 충격하중이 작용되는 경우, 다중으로 폭넓게 충격하중을 분산시키고, 특히 초기의 충격이 사이드프레임(11)과 보강판(14)에 의해 차체로 분산되도록 하여, 도어가 실내쪽으로 침입하는 것을 억제하도록 한다.The present invention configured as described above is in close contact with the side portion of the inner panel 61 bent in multiple stages and the bent surface of the side frame 11, the junction 51 of the impact bar 50 and the inner panel 61 Positioned so as to overlap the side frame 11 and the reinforcement plate 14, the impact bar 50 and the junction 51 is supported by the bracket 52, when the impact load is applied due to the side impact of the vehicle, Therefore, the impact load is widely distributed, and in particular, the initial impact is distributed to the vehicle body by the side frame 11 and the reinforcement plate 14, so that the door is prevented from invading the interior.

따라서, 이러한 본 발명은 도어의 내측판넬(61)과 외측판넬(62) 및 리어펜더부가 다중으로 중첩되어, 충격하중이 폭넓게 분산되도록 하므로, 충격을 효율적으로 완충시키고 차체의 변형을 억제하여, 실내의 착좌한 승원의 안전성이 향상되도록 한다.Therefore, the present invention overlaps the inner panel 61, the outer panel 62 and the rear fender portion of the door multiplely, so that the impact load is widely distributed, thereby efficiently cushioning the impact and suppressing deformation of the vehicle body, Improve the safety of occupants of seated occupants.

여기서 미실명부호 70은 먼지 및 소음등을 차단하도록 하는 커버이다.The unreal name 70 is a cover to block the dust and noise.

이상에서 살펴본 바와 같이, 본 발명은 정션이 내측판넬의 최외곽부까지 연장되고 브라켓에 의해 정션 내측부가 지지되며, 사이드프레임과 휠아크판넬 사이에 보강판이 결합되어, 도어부가 다중으로 중첩되도록 하므로, 측면부 충돌시 차체의 변형과 도어의 실내 침입을 효과적으로 억제하도록 하는 매우 유용한 것이다.As described above, in the present invention, the junction extends to the outermost part of the inner panel, the junction inner part is supported by the bracket, and a reinforcing plate is coupled between the side frame and the wheel arc panel, so that the door part is overlapped multiplely. It is very useful to effectively suppress the deformation of the vehicle body and the intrusion of the interior of the door during side impact.
