본 고안은 차량, 특히 승용차의 도어에 설치되어 측면충돌시 탑승자를 보호하기 위한 임팩트바아(Impact bar)의 개량된 구조에 관한 것이다.The present invention relates to an improved structure of an impact bar installed on a door of a vehicle, in particular a passenger car, to protect the occupant in the event of a side collision.

차량의 고급화와 더불어 운전자나 탑승자의 안전을 위하여 여러 안전장치가 차량에 부가되고 있는데 본 고안과 관련하여 측면충돌시 탑승자를 보호하기 위한 임팩트바아는 제1도와 같이 도어에 수평방향으로 설치되어 강성을 유지하게 된다.Various safety devices are added to the vehicle for the safety of the driver and the passenger as well as the luxury of the vehicle. The impact bar for protecting the occupant in the event of a side collision in accordance with the present invention is installed horizontally on the door as shown in FIG. Will be maintained.

즉, 도어(10)는 제1도와 같이 인너패널(6)과 아웃패널(8)로 구성되는 패널 앗세이(12)와 웨더스트립(14), 글래스(16), 채널(18)등으로 외형이 구성되고, 도어 메카니즘이 내장되는 패널 앗세이(12)에는 글래스 승강용의 레귤레이터를 비롯하여 록커 등이 설치된다.That is, the door 10 has a panel assembly 12, a weather strip 14, a glass 16, a channel 18, and the like, including the inner panel 6 and the out panel 8 as shown in FIG. In this structure, the panel assembly 12 in which the door mechanism is incorporated is provided with a locker as well as a regulator for glass lifting.

또한, 도어 패널 앗세이(12)의 인너패널(6)에는 제2도와 같은 임팩트바아(20)가 설치되는 바, 그 위치는 제3도의 단면으로 보는 바와 같이 아웃패널(8)과 인너패널(6)이 결합되는 패널앗세이(12)의 내부에 인너패널(6)과 용접시켜 설치한다.In addition, an impact bar 20 as shown in FIG. 2 is installed in the inner panel 6 of the door panel assembly 12, and the position thereof is as shown in the cross section of FIG. 6) is installed by welding with the inner panel 6 inside the panel assembly 12 to which it is coupled.

따라서, 화살표 방향으로 외부에서 충격이 가해지면, 즉 측면충돌이 발생되면 그 충격이 아웃패널(8)을 밀치고 들어와 임택트바아(20)에 까지 전해지며, 큰 충격일 경우 이 임팩트바아(20)가 충격을 흡수하게 되며, 이때 인너패널(6)과의 결합부분을 통해 인너패널(6)까지 충격을 흡수하게 되므로 차내의 운전자나 탑승자는 보다 안전한 상태로 충돌로 부터 보호되도록 한 것이다.Therefore, when an impact is applied from the outside in the direction of the arrow, that is, when a side collision occurs, the impact pushes the outer panel 8 and reaches the impact bar 20, and in the case of a large impact, the impact bar 20. Is to absorb the shock, at this time it is to absorb the shock to the inner panel 6 through the coupling portion with the inner panel (6), so that the driver or passenger in the car to be protected from a collision in a safer state.

그런데, 종래의 임팩트바아(20)는 제2도와 제3도에서 보는 바와 같이 인너패널(6)에 단일판으로 용접설치되는 것으로, 임팩트바아(20) 전체 길이에 비해 설치되는 용접부(22)가 작기 때문에 차량 충돌이 발생하여 임팩트바아(20)가 밀려 들어가면 용접부(22)가 쉽게 이탈되는 문제가 있게 된다.However, the conventional impact bar 20 is welded to the inner panel 6 as a single plate, as shown in FIG. 2 and FIG. 3, and the welded part 22 which is installed compared to the overall length of the impact bar 20 is provided. When the impact bar 20 is pushed in because of the small vehicle collision is small because there is a problem that the weld 22 is easily separated.

결국, 종래의 차량에서 임팩트바아는 형식적인 설치에 불과할 수도 있기 때문에 이의 개선책이 절실했던 것이다.As a result, the impact bar in the conventional vehicle may be only a formal installation, so the improvement was urgently needed.

이에 본 고안에서는 임팩트바아가 인너패널과 용접되는 부위를 넓히는데 착안하여 보강구조를 개선시키고자 한 것이며, 이 경우 용접부위의 용적만 넓힌다고 강성이 증대되는 것은 아니므로 별도의 브라켓을 매개로 임팩트바아를 설치하여 임팩트 바아는 인너패널에 대해 용접부가 두군데 이상으로 늘어나므로 종래에 비해 충격에 대비한 임팩트바아의 기능이 두배이상 강해지는 효과를 얻을 수 있게 된다.In this design, the impact bar is intended to improve the reinforcement structure by focusing on widening the welded area with the inner panel, and in this case, the rigidity is not increased by only expanding the volume of the welded part, so the impact is provided through a separate bracket. By installing a bar, the impact bar has more than two welds on the inner panel, so the impact bar function can be more than twice stronger than the conventional bar.

이하 첨부도면을 참고 하여 본 고안을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 고안은 패널앗세이(12)를 이루는 도어의 인너패널(6)내의 용접부(22)에 Z자형 브라켓(24)일단을 용접설치하고, 브라켓(24)의 타단에 임팩트바아(20) 후면을 용접결합시키며, 상기 용접부(22)에 임팩트바아(20)의 연장된 전면부(26)를 용접설치하여서 된 임팩트바아 설치구조이다.The present invention welds one end of the Z-shaped bracket 24 to the welded portion 22 in the inner panel 6 of the door constituting the panel assembly 12, and the rear of the impact bar 20 on the other end of the bracket 24. The welding bar is an impact bar mounting structure formed by welding the extended front part 26 of the impact bar 20 to the welding part 22.

제4도는 본 고안에 따른 임팩트바아(20)와 브라켓(24)의 결합상태를 설명하기 위해 이면에서 도시된 도면으로, 연장된 전면부(26)와 브라켓(24)이 겹쳐져 결합된 상태를 보여준다.Figure 4 is a view from the back to illustrate the coupling state of the impact bar 20 and the bracket 24 according to the present invention, shows an extended front portion 26 and the bracket 24 is coupled to the overlapping state .

여기서, 브라켓(24)은 하나만 도시하였으나, 임팩트바아(20)양단에 하나씩 각각 설치되는 것이지만 구성이 동일하여 생략 되었다(이하 같다)Here, although only one bracket 24 is shown, one is installed on each of the ends of the impact bar 20, but the configuration is the same (omit below)

제5도는 본 고안에 따른 임팩트바아가 도어내에 설치된 결합 횡단면도로서 임팩트바아(20)와 브라켓(24)을 도어에 설치하여 전체를 단면으로 처리한 도면으로, 패널앗세이(12)를 구성하는 인너패널(6)과 아웃패널(8)의 형상과 구조는 변화가 없다.5 is a cross-sectional view of the impact bar installed in the door according to the present invention, the impact bar 20 and the bracket 24 are installed on the door, and the entire bar is processed in a cross-section. The shape and structure of the panel 6 and the out panel 8 are unchanged.

다만, 종래의 용접부(22) 위치에 브라켓(24)을 매개로 임팩트바아(20)의 전면부(26)와 브라켓(24)의 일단 및 인너패널(6)이 함께 용접되고, Z자형 브라켓(24)의 타단은 임팩트바아(20)의 후면부와 용접된 구조이므로 당연히 브라켓(24)의 높이(상하 두께)는 임팩트바아(20)가 꼭맞게 끼워질 수 있는 높이로 제작된다.However, the front portion 26 of the impact bar 20 and one end of the bracket 24 and the inner panel 6 are welded together by the bracket 24 at the position of the conventional welding portion 22, and the Z-shaped bracket ( Since the other end of the 24 is welded to the rear portion of the impact bar 20, the height (up and down thickness) of the bracket 24 is naturally manufactured to a height at which the impact bar 20 can be fitted.

상기한 구성에 따라 임팩트바아가 용접되는 부위는 인너패널과 브라켓이 결합되는 곳과, 인너패널 후면부와 브라켓의 타단이 용접되는 곳이 된다.According to the above configuration, the area where the impact bar is welded is the place where the inner panel and the bracket are coupled, and the other end of the inner panel rear portion and the bracket is welded.

상기와 같은 결합구조의 임팩트바아에서 측면충돌이 발생되면, 먼저 아웃패널(8)이 밀려 들어올 것이고, 더 큰 충돌에 의해 임팩트바아(20)의 전면부(26)에 충격이 가해지면 용접부(22)에 전달되면서 인너패널(6)로 충격이 전달되어 흡수된다.When a side collision occurs in the impact bar of the coupling structure as described above, the out panel 8 will be pushed in first, and when the impact is applied to the front part 26 of the impact bar 20 by a larger collision, the welded part 22 The shock is transmitted and absorbed by the inner panel 6 while being transmitted to the inner panel 6.

그러나, 이때 브라켓(24)을 통해 임팩트바아(20) 후면부와 용접된 곳으로도 충격이 분산되면서 충격을 흡수하므로 보강능력이 종래에 비해 두배이상 향상되는 것이다.However, since the shock is absorbed while the impact is distributed to the place where the impact bar 20 is welded through the bracket 24, the reinforcement ability is more than doubled compared to the conventional art.

이러한 보강력 증강은 탑승자의 인명보호에 지대한 영향을 발휘하며, 만일 경미한 충격으로 임팩트바아(20)가 감당할 수 있는 정도라면 다른 부품파손없이도 수리 할 수 있으므로 차량유지관리에도 실용성을 배가시키게 된다.This reinforcement reinforcement exerts a great influence on the protection of the occupants, and if the impact bar 20 can be afforded by a slight impact can be repaired without damaging other parts, thereby increasing the practicality in vehicle maintenance.

상기와 같이 본 고안은 브라켓을 추가하는 것만으로 임팩트바아의 기능을 향상시키고, 강성이 크게 증대되며, 별도의 구조변경없이 조립되어지므로 탑승자보호와 차량유지관리 측면에서 매우 좋은 효과를 얻을 수 있게 된다.As described above, the present invention improves the function of the impact bar by simply adding the bracket, greatly increases the rigidity, and is assembled without any structural change, thereby obtaining a very good effect in terms of occupant protection and vehicle maintenance. .
