본 발명은 자동차의 도어(door)의 구조에 관한 것으로서, 특히 외측판넬과 임팩트바의 취부구조를 개선하여, 외측판넬의 강성이 향상되도록 하므로, 측면부 충돌시 외측판넬의 변형이 효과적으로 억제되도록 하는 자동차 도어의 장강성 보강구조에 관한 것이다.The present invention relates to a structure of a door of a vehicle, and in particular, to improve the mounting structure of the outer panel and the impact bar, so that the rigidity of the outer panel is improved, the vehicle to effectively suppress the deformation of the outer panel during side impact The present invention relates to a long rigid reinforcement structure of a door.

종래 자동차의 도어는, 제1도와 제2도에 도시되는 바와 같이, 내측판넬(11)과 외측판넬(12)이 절곡되어 소정의 공간을 형성하는 결합되고, 내부 공간 양측부에 각기 정션(junction)(13)이 용접에 의해 내측판넬(11)에 부착되고, 양쪽의 정션(13)에 중공의 환봉으로 된 임팩트바(impact bar)(20)의 양단부가 지지되어, 차량의 측면부에 충격하중이 작용되는 경우, 임팩트바(20)가 파손된 외측판넬(12)의 진입을 억제하고 충격에너지를 흡수하여, 실내에 승차한 승원이 보호되도록 되어있다.As shown in FIGS. 1 and 2, a door of a conventional vehicle is coupled to bend the inner panel 11 and the outer panel 12 to form a predetermined space, and junctions are provided at both sides of the inner space. (13) is attached to the inner panel (11) by welding, and both ends (13) are supported at both ends of the impact bar (20), which is a hollow round bar, to impact the side surface of the vehicle. In this case, the impact bar 20 suppresses the entry of the damaged outer panel 12, absorbs the impact energy, and protects the occupant in the cabin.

그러나, 이러한 종래 자동차 도어는, 외측판넬(12)과 임팩트바(20)가 소정 간격을 두고 설치되어, 차량의 측면부 충돌로 외측판넬(12)에 충격하증이 작용되는 경우, 외측판넬(12)이 쉽게 변형되고, 실내쪽으로 침입하게 되는 문제점이 있었다.However, such a conventional car door, the outer panel 12 and the impact bar 20 is provided at a predetermined interval, when the impact load on the outer panel 12 due to the side impact of the vehicle, the outer panel 12 This easily deformed, there was a problem to break into the room.

본 발명의 목적은 상기와 같은 종래의 문제점을 해결하기 위해, 임팩트바의 외주면을 덮는 보강판을 구조용충진제에 의해 외측판넬에 취부하여, 외측판넬의 장강성이 향상되도록하므로 외력에 의한 외측판넬의 변형을 억제하는 자동차 도어의 장강성 보강구조를 제공하는 데 있다.An object of the present invention is to solve the conventional problems as described above, by mounting a reinforcing plate covering the outer circumferential surface of the impact bar to the outer panel by the structural filler, so that the stiffness of the outer panel to improve the outer panel by the external force It is to provide a high rigidity reinforcement structure of the automobile door that suppresses deformation.

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 발명은 제3도와 제4도에 도시된 바와같이 내측판넬(11)과 외측판넬(12)이 절곡되어 소정의 공간을 두고 결합되고, 내부 공간 양측부에 각기 정션(13)이 용접에 의해 부착되며, 양쪽의 정션(13)에 중공의 환봉으로 된 임팩트바(20)의 양단부가 지지되고, 임팩트바(20)의 외주면을 덮고 상하 양쪽으로 소정폭 절곡 연장되는 보강판(30)이 구조용충진제(31)에 의해 외측판넬(12)의 내부면에 결합됨을 그 기술적 구성상의 기본 특징으로 한다.In the present invention, as shown in FIG. 3 and FIG. 4, the inner panel 11 and the outer panel 12 are bent and joined to a predetermined space, and the junctions 13 are respectively welded to both sides of the inner space. The reinforcement plate 30 is attached to both junctions 13 and is supported at both ends of the impact bar 20 made of a hollow round bar, covering the outer circumferential surface of the impact bar 20 and extending bent a predetermined width up and down both sides. Coupled to the inner surface of the outer panel 12 by the filler 31 is a basic feature of the technical configuration.

여기에서, 보강판(30)은 일정 반경을 가지는 곡면으로 상하단에 결합용 플랜지가 축방향을 따라 일정 간격으로 형성되어, 임팩트바(20)의 외주면에 곡면부가 취부되고, 상하방향으로 연장된 플랜지부가 구조용충진제(31)에 의해 외측판넬(12)의 내부면에 취부된다.Here, the reinforcing plate 30 is a curved surface having a predetermined radius, the coupling flange is formed at regular intervals along the axial direction at the upper and lower ends, the curved surface portion is mounted on the outer peripheral surface of the impact bar 20, the flange extending in the vertical direction It is attached to the inner surface of the outer panel 12 by the additional structural filler (31).

이와같이 구성되는 본 발명은, 임팩트바(20)가 보강판(30)과 일체로 외측판넬(12)에 취부되어, 외측판넬(12)의 강성이 향상되도록 하므로, 도어의 외측판넬(12)에 충격하중이 작용되는 경우, 외측판넬(12)이 압축되는 것과 벤딩되는 것을 억제하게 된다.According to the present invention configured as described above, the impact bar 20 is integrally mounted to the outer panel 12 integrally with the reinforcing plate 30 so that the rigidity of the outer panel 12 can be improved. When the impact load is applied, the outer panel 12 is suppressed from being compressed and bent.

따라서, 이러한 본 발명은 측면부 접촉 등의 사고로 외측판넬(12)에 충격하중이 작용되는 경우, 도어 외측판넬(12)이 실내쪽으로 침입되는 것과 변형되는 것을 효과적으로 억제하게 된다.Therefore, the present invention effectively suppresses the intrusion and deformation of the door outer panel 12 into the interior when the impact load is applied to the outer panel 12 due to an accident such as side contact.

이상에서 살펴본 바와 같이, 본 발명은 임팩트바의 외주면을 덮는 보강판이 구조용충진제에 의해 외측판넬에 취부되어, 외측판넬의 강성이 향상되도록 하므로, 외측판넬의 변형을 효과적으로 억제하는 매우 유용한 것이다.As described above, the present invention is a reinforcing plate covering the outer circumferential surface of the impact bar is mounted on the outer panel by the structural filler, so that the rigidity of the outer panel is improved, it is very useful to effectively suppress the deformation of the outer panel.
