Abstract
본 고안은 자동차 도어에 있어서, 특히 측면부를 보강시켜 충돌시에 도어의 파손을 방지하고 더 나아가 탑승자를 보호하도록 설계된 자동차도어 구조에 관한 것이다.The present invention relates to an automobile door structure, in particular designed to reinforce the side part to prevent breakage of the door in the event of a collision and further protect the occupant.
종래 도어는 대개가 아웃패널(10)과 인너패널(12)로 도어 외형을 형성하고, 그 사이에는 도어글래스와 이를 승강시키기 위한 작동기구들이 설치되어서, 실제로 측면충돌을 당했을때 운전자를 보호하기 위한 보강대는 거의 상기 패널(10,12)이 담당하게 되고, 이보다 개선시켜 임팩트바아를 설치한 것도 있지만, 그 자체가 충격을 흡수하지 못하고 강성만 갖기 때문에 충분한 강성을 갖지 못하는 도어는 탑승자를 보호하지 못하는 단점이 있었던 것이다.Conventional doors are usually formed with the outer panel 10 and the inner panel 12, and the door glass and the actuating mechanisms for elevating them are installed therebetween to protect the driver in the event of a side collision. The panel (10, 12) is in charge of the reinforcement, and the impact bar has been installed to improve than this, but the door does not have enough rigidity to protect the occupants because it does not absorb the shock itself and has only rigidity This was there.
이에 본 고안은 임팩트바아와 병설되는 브라켓이 인너패널과 폐공간을 이루고, 폐공간내에는 충격흡수재를 채워서 이 브라켓이 충격량을 흡수함과 동시에 보다 견고한 차체바닥으로 그 충격을 전달시키도록 하므로써 피해를 최소화시키도록 한 것이다.Therefore, the present invention provides a damage space between the impact bar and the inner panel and the inner panel, and the shock absorbing material is filled in the waste space to absorb the impact and to deliver the impact to the solid body floor. It is to be minimized.

본 고안은 자동차 도어에 있어서, 특히 측면부를 보강시켜 충돌시에 도어의 파손을 방지하고 더나아가 탑승자를 보호하도록 설계된 충격흡수재가 내장된 자동차 도어 구조에 관한 것이다.The present invention relates to an automobile door structure in which an impact absorbing material is designed to reinforce the side part, in particular, to prevent breakage of the door during a collision and further protect the occupant.
자동차, 특히 승용차에서 도어는 승하차를 위해서도 사용되지만 탑승후의 탑승자보호를 위해 많은 보강구조가 개발되어 있다.In automobiles, especially passenger cars, doors are also used for getting on and off, but many reinforcing structures have been developed to protect occupants after boarding.
한편, 상기 도어는 측면충돌시에 임팩트바아(Impact Bar)부위가 가장 먼저 충격을 받게되며, 그 충격량은 제1도의 A부분에서 차실측으로 가장 크게 작용하게 되는 것이 실험과 사용결과에서 밝혀져 있다.On the other hand, the door is the impact bar (Impact Bar) area is first impacted during the side impact, the impact amount is found to be the largest acting on the vehicle side in the portion A of Figure 1 has been found in the experiment and use results.
그럼에도 불구하고, 종래 도어는 대개가 아웃패널(10)과 인너패널(12)로 도어 외형을 형성하고, 그 사이에는 도어글래스와 이를 승강시키기 위한 작동기구들이 설치되어서, 실제로 측면충돌을 당했을때 운전자를 보호하기 위한 보강대는 거의 상기 패널(10,12)이 담당하게 되고, 이보다 개선시켜 임팩트바아를 설치한 것도 있지만, 그 자체가 충격을 흡수하지 못하고 강성만 갖기 때문에 충분한 강성을 갖지못하는 도어는 탑승자를 보호하지 못하는 단점이 있었던 것이다.Nevertheless, conventional doors are usually formed with the outer panel 10 and the inner panel 12, and the door glass and operating mechanisms for elevating the door are installed therebetween, so that when the driver actually encounters a side collision The reinforcement for protecting the panel is almost the panel (10, 12) is in charge, and some improvements have been installed to the impact bar, but the door itself does not have sufficient rigidity because it does not absorb the impact and only has rigidity, There was a disadvantage of not protecting.
이에 본 고안은 인너패널과 폐공간을 이루는 브라켓을 설치하여 보강구조를 이루게 하되, 이 브라켓내의 폐공간에 발포제인 충격흡수재를 내장시켜 큰 완충기능을 갖도록 한 것이다.The present invention is to provide a reinforcing structure by installing a bracket constituting the inner panel and the closed space, to have a large cushioning function by embedding a shock absorber, a foaming agent in the closed space in the bracket.
또한, 측면충돌시 임팩트바아와 보호대는 밀려들어가면서 일차로 충격을 흡수하고, 도어 하단의 실사이드 지지력에 의해 차체바닥으로 충격을 전달시켜 차체는 손상이 오더라도 탑승자는 보호되는 기능을 갖도록 한 것이다.In addition, the impact bar and the guard in the case of a side impact is absorbed as the primary shock absorbed, and by passing the shock to the bottom of the body by the seal-side support of the lower door to ensure that the occupants have a function to protect even if damage.
이하 본 고안을 첨부도면에 의거하여 보다 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
본 고안은 도어(1)의 아웃패널(10)과 인너패널(12)사이에 임팩트바아(14)를 설치하고, 이 임팩트바아(14)와 접촉되도록 보호대(16)를 설치하며, 인너패널(12)과 그단면이 폐공간을 이루도록 브라켓(18)을 설치하되, 브라켓(18)내면의 폐공간에 충격흡수재(24)를 내장시킨 자동차 도어구조이다.The present invention is to install an impact bar 14 between the outer panel 10 and the inner panel 12 of the door (1), to install a guard 16 to contact the impact bar 14, the inner panel ( 12) and the end surface of the bracket 18 is installed so as to form a closed space, the shock absorbing material 24 is built in the closed space of the inner surface of the bracket 18 is a car door structure.
도면중 미설명부호 20은 도어하단의 실사이드, 22는 차내바닥이다.In the figure, reference numeral 20 is a seal side at the bottom of the door, and 22 is a bottom of the vehicle.
제2도는 본 고안이 설치된 도어상의 위치를 도시한 것이고, 제3도는 제2도의 B-B선 단면도이다.2 is a view showing a position on a door in which the present invention is installed, and FIG. 3 is a sectional view taken along line B-B in FIG.
여기서, 임팩트바아(14)는 수평상태보다는 후방쪽, 즉 차체바닥쪽으로 다소 기울듯이 배치되며, 보호대(16)하단은 인너패널(12)과 용접된 구조를 보여준다.Here, the impact bar 14 is disposed to be inclined somewhat toward the rear side, that is, the bottom of the vehicle body rather than a horizontal state, and the lower portion of the guard 16 shows a welded structure with the inner panel 12.
또한, 브라켓(18)은 임팩트바아(14) 뒤로 보호대(16)로부터 일정간격을 두고 설치되어서 만일의 충격시 브라켓(18)의 전면에 보호대(16)에 접촉되게 되고, 브라켓(18)과 인너패널(12)이 이루는 폐공간은 충격흡수재(24)로 충만되어있다.In addition, the bracket 18 is installed behind the impact bar 14 at a certain interval from the guard 16 so that in case of an impact, the bracket 18 is in contact with the guard 16 on the front of the bracket 18, and the bracket 18 and the inner The closed space formed by the panel 12 is filled with the shock absorber 24.
상시한 구성을 이루는 본 고안이 적용된 도어(1)에 만일 측면충돌이 발생되면 아웃패널(10)이 밀려들어오면서 임팩트바아(14)와 보호대(16)가 차례로 밀려 들어온다.If a side collision occurs in the door 1 to which the subject innovation of the present invention is applied, the impact bar 14 and the guard 16 are sequentially pushed in while the panel 10 is pushed in.
이때의 충격은 일차로 임팩트바아(14)와 보호대(16)를 밀면서 브라켓(18)으로 전해지며, 충격흡수재(24)는 보다 큰 완충기능을 발휘하면서 인너패널(12)을 밀고, 더 큰충격은 비교적 튼튼한 구조를 갖는 실사이드(20)와 차내바닥(22)에 전달되어 결국 운전자를 보호하게 되는 것이다.At this time, the impact is first transmitted to the bracket 18 by pushing the impact bar 14 and the guard 16, the shock absorber 24 pushes the inner panel 12 while exhibiting a greater shock absorbing function, the greater impact Is delivered to the sealside 20 and the vehicle floor 22 having a relatively strong structure to eventually protect the driver.
여기서, 임팩트바아(14)는 그 보호대(16) 및 브라켓(18)은 더불어 차내 바닥(22)쪽으로 경사져 설치되기 때문에 외부에 큰충격은 실사이드(20)와 차내(22)쪽으로 전달됨은 자명한 일인 것이다.Here, since the impact bar 14 has its guard 16 and the bracket 18 inclined toward the bottom 22 of the vehicle, it is obvious that the impact bar 14 is transmitted to the seal side 20 and the inside of the vehicle 22. It is work.
상시와 같은 본 고안을 사용함에 따라 차량의 측면충돌시 탑승자를 보호할 수 있고 작은 충격에는 도어를 보호할 수 있는 강성증대효과를 얻을 수 있다.By using the present invention as always, it is possible to protect the occupant during the side collision of the vehicle and to obtain a rigidity increase effect to protect the door in a small impact.
