본 고안은 승용차의 리어 도어와 리어 사이드에 측면충돌에 대한 충격보강을 하기 위한 보강구조에 관한 것이다.The present invention relates to a reinforcing structure for impact reinforcement against side collisions on the rear door and the rear side of a passenger car.

종래에는 제 3 도와 같이, 리어 사이드 외측패널(31)과 휠 하우스 내측패널(32)로 이루어진 리어 사이드를 구비하고, 상기 휠 하우스 내측패널(32)은 휠 하우스(33)와 용접하고 있다.Conventionally, as shown in the third diagram, a rear side including a rear side outer panel 31 and a wheel house inner panel 32 is provided, and the wheel house inner panel 32 is welded to the wheel house 33.

또 상기 리어 사이드의 리어 사이드 외측패널(31)과 접하는 리어 도어는 도어 내측패널(34)과 도어 외측패널(35)의 연접부에 브래킷(36)을 설치하고, 도어 외측패널(35)의 내면쪽에 임팩트 빔(37)이 가설되도록 하고 있다.In addition, the rear door which is in contact with the rear side outer panel 31 of the rear side is provided with a bracket 36 at the junction of the door inner panel 34 and the door outer panel 35, and the inner surface of the door outer panel 35. The impact beam 37 is constructed on the side.

그러나 상기와 같은 구조에서는 측면충돌에 따른 충격하중이 화살표방향으로 작용할 때, 특히 리어 도어 측단부, 즉 도어 내측패널(34)과 도어 외측패널(35)의 연접부와, 리어 사이드부의 밀리는 정도가 커 제 3 도 가상선과 같이 찌그러지므로 실내에 있는 승객에 가해지는 충격량이 그 만큼 커져 승객상해치가 치명적인 수준에 달하고 있는 문제를 가지고 있었다.However, in the structure as described above, when the impact load due to the side collision acts in the direction of the arrow, in particular, the degree of sliding of the rear door side end portion, that is, the junction between the door inner panel 34 and the door outer panel 35, and the rear side portion are pushed. Since the third road is distorted like a virtual ship, the impact on the passengers in the room is increased so much that the injury to the passengers is fatal.

본 고안의 목적은 리어 도어와 리어 사이드의 접하는 부분을 보강하여 인체 상해치를 낮추는데 있는 것이다.An object of the present invention is to reinforce the contact portion of the rear door and the rear side to lower the human injury.

본 고안은 상기 목적을 달성하기 위하여, 리어 사이드 외측패널 내면에 리어 사이드 보강부재를 용접하고, 도어 외측패널 단부내에서 임팩트 빔과 용접되는 브래킷과 도어 내측패널 측단부의 내면간에 도어 보강부재를 용접한 것이다.In order to achieve the above object, the present invention welds the rear side reinforcement member to the inner surface of the rear side outer panel, and welds the door reinforcement member between the inner surface of the door inner panel side end and the bracket welded to the impact beam in the door outer panel end portion. It is.

이하 실시예를 도면에 의하여 설명한다.Embodiments will be described below with reference to the drawings.

본 고안은 제 2 도에 도시하는 바와 같이, 리어 사이드 외측패널(1) 내면 중간에 약간의 중공이 형성되도록 리어 사이드 보강부재(2)를 용접(스폿용접)하고, 도어 내측패널(3) 측단부의 내면과 브래킷(4)면간에 U자형의 도어 보강부재(5)를 용접(스폿용접)시킨 것이다.According to the present invention, as shown in FIG. 2, the rear side reinforcing member 2 is welded (spot welded) so that a slight hollow is formed in the middle of the inner surface of the rear side outer panel 1, and the door inner panel 3 side is formed. The U-shaped door reinforcing member 5 is welded (spot welded) between the inner surface of the end portion and the surface of the bracket 4.

상기한 리어 사이드 외측패널(1)은 휠 하우스 내측패널(6)과 함께 리어 사이드를 이루고 있고, 상기 휠 하우스 내측패널(6)은 하우징(7)에 용접된다.The rear side outer panel 1 forms a rear side together with the wheel house inner panel 6, and the wheel house inner panel 6 is welded to the housing 7.

또한 상기한 도어 내측패널(3)은 도어 외측패널(8)과 함께 리어 도어를 이루는 바, 상기 도어 내측패널(3)과 도어 외측패널(8)의 연접부 내에는 브래킷(4)이 설치된다. 상기 브래킷(4)은 도어 외측패널(8) 내면쪽에 가설되는 임팩트 빔(9)의 일단을 지지하고 있도록 용접시킨 것이다.In addition, the door inner panel 3 forms a rear door together with the door outer panel 8, and a bracket 4 is installed in the junction between the door inner panel 3 and the door outer panel 8. . The bracket 4 is welded to support one end of the impact beam 9 which is installed on the inner surface side of the door outer panel 8.

따라서 도어 외측패널(8)면에 측면충돌이 일어났을 때 그 충격하중은 리어 도어와 리어 사이드에 미치지만 리어 사이드 보강부재(2)와 도어 보강부재(5)가 강도 보강을 하고 있기 때문에 쉽게 밀리지 않게 된다.Therefore, when a side collision occurs on the outer surface of the door 8, the impact load reaches the rear door and the rear side, but the rear side reinforcement member 2 and the door reinforcement member 5 are easily pushed because they are reinforced with strength. Will not.

이와 같은 본 고안은 상기와 같이 리어 사이드와 리어 도어내에 보강부재를 추가하고 있기 때문에 실내측으로의 충격량과 변위가 작아 인체상해치중 골반부에 해당하는 펠비스(pelvis) 값이 감소하게 되는 것이다.As such, the present invention adds a reinforcing member in the rear side and the rear door as described above, so that the impact amount and displacement to the interior side are small, so that the pelvis value corresponding to the pelvis is reduced during the injury.
