본 고안은 차량용 도어 임팩트 바아의 보강구조에 관한 것으로, 특히 차량용 임팩트 바아의 취부구조를 개선함으로써 보다 확실하게 임팩트 바아를 지지할 수 있을 뿐만 아니라 측면 충돌시 임팩트 바아의 차실내 침입을 막을 수 있도록 된 차량용 도어 임팩트 바아의 보강구조에 관한 것이다.The present invention relates to a reinforcing structure of a door impact bar for a vehicle, and in particular, by improving the mounting structure of the impact pad for a vehicle, it is possible not only to support the impact bar more reliably but also to prevent the impact bar from invading the interior of the impact bar during a side collision. A reinforcing structure of a door impact bar for a vehicle.

일반적으로 차량용 도어 임팩트 바아의 보강구조는 대개 제4도와 제5도에 도시된 바와 같은 구조로 되어 있다.In general, the reinforcement structure of the door impact bar for a vehicle is usually as shown in FIGS. 4 and 5.

즉, 한쪽은 평탄으로 되어 있고, 다른 한쪽은 반원형상으로 되어진 일체형 보강부재(10)를 원통형상의 임팩트 바아(20)의 한쪽선단을 파지한 상태로 내측 도어판넬(30)에 용접 취부시킴으로써 보강되도록 한 구조이다.That is, one side is flat and the other side is reinforced by welding the integral reinforcing member 10, which is semi-circular, to the inner door panel 30 while holding one end of the cylindrical impact bar 20. It is a structure.

그러나 이와 같은 구조의 보강구조는 임팩트 바아(20)와 보강부재(10)가 동일선상에 취부됨으로써 차량의 측면 충돌시 용접된 부위가 쉽게 떨어져 나가며 임팩트 바아(20)가 충분히 충돌 에너지를 흡수하기에 어럽다는 결점이 있었다.However, the reinforcing structure of such a structure is that the impact bar 20 and the reinforcing member 10 are mounted on the same line, so that the welded portions easily fall off during the side impact of the vehicle, and the impact bar 20 sufficiently absorbs the collision energy. There was a drawback of being unclean.

이에 본 고안은 상기와 같은 제반 결점을 해소하기 위하여 안출된 것으로, 보강부재의 형상을 변경하여 임팩트 바아를 취부시킴으로써, 측면 충돌에 의한 충돌 에너지를 보다 효과적으로 흡수하도록 된 차량용 도어 임팩트 바아의 보강구조를 제공함에 그 목적이 있다.Therefore, the present invention was devised to solve the above-mentioned drawbacks, and by modifying the shape of the reinforcing member and attaching the impact bar, the reinforcing structure of the door impact bar for a vehicle to absorb the impact energy caused by the side collision more effectively. The purpose is to provide.

상기와 같은 목적을 달성하기 위한 본 고안은, ㄷ자형상으로 이루어진 보강부재와; 상기 보강부재의 한쪽 선단에 형성된 플랜지와; 상기 보강부재의 본체 중앙부에 형셩된 홈부를 포함하며, 임팩트 바아가 상기 홈부에 끼워진 상태로 내측 도어판넬의 내측면 상의 일부에 용접되고, 상기 플랜지는 내측 도어판넬의 다른 일부에 부착되어 보강부재를 지지하도록 하는 차량용 도어 임팩트 바아의 보강구조를 제공한다.The present invention for achieving the above object, and a reinforcing member made of a U-shape; A flange formed at one end of the reinforcing member; A groove formed in the central portion of the main body of the reinforcing member, the impact bar being welded to a portion on the inner side of the inner door panel while the impact bar is fitted into the groove, and the flange is attached to another part of the inner door panel to provide the reinforcing member. It provides a reinforcement structure for the vehicle door impact bar to support.

이하 본 고안을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제1도는 본 고안에 따른 임팩트 바아의 보강구조가 적용된 차량용 도어의 사시도이고, 제2도는 제1도의 A-A선 단면도이며, 제3도 (A), (B)는 본 고안에 따른 보강재의 사시도로서, 본 고안은 도면에 도시된 바와 같이 ㄷ자형상으로 이루어진 보강부재(5)의 한쪽 선단에 플랜지(5a)를 형성시키고, 본체의 중앙에는 홈부(5b)를 만들어 임팩트 바아(2)의 한쪽선단이 상기 홈부(5b)에 끼워져 내측 도어판넬(3)에 고정취부되는 구조로 되어 있다.1 is a perspective view of a door for a vehicle to which the reinforcement structure of the impact bar according to the present invention is applied, FIG. 2 is a sectional view taken along line AA of FIG. 1, and FIGS. 3A and 3B are perspective views of the reinforcing material according to the present invention. In the present invention, the flange 5a is formed at one end of the reinforcing member 5 having a U-shape as shown in the figure, and a groove 5b is formed at the center of the main body so that one end of the impact bar 2 is formed. It fits in the groove part 5b and is fixed to the inner door panel 3.

따라서 이와 같은 구조로 취부되는 보강부재(5)를 갖춘 차량용 임팩트 바아(2)는 기존의 구조보다 외부의 충돌에 의한 에너지 흡수를 보다 더 확실하게 할 수 있는 효과가 있게 된다.Therefore, the impact bar for the vehicle 2 having the reinforcing member 5 mounted in such a structure has the effect of more reliably absorbing energy due to external collision than the existing structure.

이상 설명한 바와 같이 본 발명 차량용 도어 임팩트 바아의 보강구조에 따르면, 보강부재의 형상이 임팩트 바아와 같은 횡방향이 아닌 ㄷ자형태의 부재로 구성되므로써 차량의 측면 충돌시 보강부재(5) 자체가 충격의 일부를 흡수하게 되어, 임팩트 바아의 차실내 침입을 효과적으로 막아 탑승객의 안전을 도모할 수 있게 된다.As described above, according to the reinforcing structure of the door impact bar for a vehicle of the present invention, since the shape of the reinforcing member is composed of a U-shaped member rather than a transverse direction such as the impact bar, the reinforcing member 5 itself is not affected by the impact on the side of the vehicle. By absorbing a portion, it is possible to effectively prevent the ingress of the impact bar into the cabin, thereby improving passenger safety.
