Description
본 발명은 도어 임팩트 빔 구조에 관한 것으로서, 특히 차량의 도어에 H형의 단면을 가지면서 전후방으로는 수평면과 수직면이 연장 구성되는 도어 임팩트 빔 구조를 적용하여 차량의 측면 충돌시 에너지 흡수율을 극대화함은 물론 도어의 실내 밀림량은 최소화하여 탑승자의 골반부 상해를 저감시킬 수 있도록 하는 골반부 상해치 저감을 위한 도어 임팩트 빔 구조에 관한 것이다.The present invention relates to a door impact beam structure, and in particular, by applying a door impact beam structure having a H-shaped cross-section in the front and rear of the vehicle door and configured to extend in a horizontal plane and a vertical plane to maximize the energy absorption rate in the side impact of the vehicle. Of course, it relates to a door impact beam structure for reducing the pelvic injury to minimize the indoor sliding amount of the door to reduce the pelvic injury of the occupants.
주지된 바와같이, 차량의 도어는 탑승자가 실내로 들어가면서 개폐하는 수단 외에도 측면 충돌시 인체 상해치를 최소화하기 위한 충돌 하중 흡수 구간의 역할을 하는 것으로, 상기 도어에는 도어 임팩트 빔이 적용되고 있다.As is well known, the door of the vehicle serves as a collision load absorbing section for minimizing the human injury in the event of a side collision in addition to the means for opening and closing as the occupant enters the room, the door impact beam is applied to the door.
즉, 종래에는 도 1 내지 도 3에 도시된 바와같이, 도어는 아우터 패널(1)과 인너패널(2)에 의해 폐단면을 이루고, 상기 아우터 패널(1)의 후방에는 도어 임팩트 빔(3)이 형성되며, 상기 도어 임팩트 빔(3)의 전후방에는 인너패널(2)에 도어 임팩트 빔(3)을 고정하기 위한 장착브라켓(4)이 결합되는 구조로 이루어져 있다.That is, conventionally, as shown in FIGS. 1 to 3, the door forms a closed cross section by the outer panel 1 and the inner panel 2, and the door impact beam 3 is located behind the outer panel 1. Is formed, and the front and rear of the door impact beam (3) has a structure in which the mounting bracket (4) for fixing the door impact beam (3) to the inner panel (2) is coupled.
그러나, 종래의 도어 임팩트 빔 구조는 단순 중공부(5)를 가지는 단면으로 구성되어 있어 에너지 흡수율이 작으며, 도어의 실내 밀림량이 과다하여 탑승자의 골반부 상해치값이 커지는 문제점을 가지고 있었다.However, the conventional door impact beam structure has a problem that the energy absorption rate is small because the cross section having the simple hollow portion 5 is small, and the indoor injury amount of the door is excessive, resulting in a large pelvic injury value of the occupant.
더불어, 종래에는 도어 임팩트 빔을 고정하기 위해 전후방에 각각 장착브라켓을 결합하여야 함으로써, 부품수 및 조립 공정이 증가되어 제조원가를 상승시키는 문제점이 있다.In addition, in the related art, mounting brackets must be coupled to the front and rear to fix the door impact beam, thereby increasing the number of parts and the assembly process, thereby increasing manufacturing costs.
따라서, 본 발명은 상기와 같은 종래의 문제점을 해결하기 위해 안출된 것으로서 본 발명의 목적은, H형의 단면을 가지면서 전후방으로는 수평면과 수직면이 연장 구성된 도어 임팩트 빔 구조를 적용함으로써, 차량의 측면 충돌시 에너지 흡수율을 극대화함은 물론 도어의 실내 밀림량은 최소화하여 탑승자의 골반부 상해를 저감시킬 수 있도록 하고, 더불어 종래 적용되었던 장착브라켓의 삭제로 부품수 및 작업 공정의 단축을 통해 제조원가를 절감할 수 있도록 하는 골반부 상해치 저감을 위한 도어 임팩트 빔 구조를 제공하려는 것이다.Accordingly, an object of the present invention is to solve the conventional problems as described above, the object of the present invention, by applying a door impact beam structure having a horizontal cross-section and a vertical plane in the front and rear while having an H-shaped cross-section, In addition to maximizing energy absorption in the event of a side impact, the indoor sliding of the door can be minimized to reduce the pelvic injury of the occupants, and the manufacturing cost can be reduced by shortening the number of parts and the work process by eliminating the mounting bracket. The purpose of the present invention is to provide a door impact beam structure for reducing pelvic injury.
이하, 첨부된 도면에 의거하여 본 발명의 바람직한 일실시예를 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

도 4 내지 도 6에 도시된 바와같이, 폐단면을 이루는 도어의 아우터 패널(11)과 인너패널(12) 사이에 도어 임팩트 빔(20)을 형성시킨 구조에 있어서,4 to 6, in the structure in which the door impact beam 20 is formed between the outer panel 11 and the inner panel 12 of the door forming a closed cross section,
상기 도어 임팩트 빔(20)은 H형의 단면을 가지도록 구성하되, The door impact beam 20 is configured to have an H-shaped cross section,
상기 도어 임팩트 빔(20)의 전후방에는 인너패널(12)의 외측면에 결합되는 수평면(21)과,Front and rear of the door impact beam 20, the horizontal surface 21 is coupled to the outer surface of the inner panel 12,
상기 수평면(21)과 함께 박스단면을 이루도록 인너패널(12)의 수직면에 취부되는 제 1 및 제 2 수직면(22)(23)을 연장 구성함을 특징으로 한다.The first and second vertical surfaces 22 and 23 mounted on the vertical surface of the inner panel 12 may be extended to form a box cross-section together with the horizontal surface 21.
다른 일면에 따라, 상기 도어 임팩트 빔(20)은, 알루미늄 재질로 압출 성형함을 특징으로 한다.According to another aspect, the door impact beam 20 is characterized in that the extrusion molding of aluminum.
이와같이 구성된 본 발명의 일실시예에 대한 작용을 첨부된 도 4 내지 도 6을 참조하여 설명하면 다음과 같다.Referring to Figures 4 to 6 attached to the operation of an embodiment of the present invention configured as described above are as follows.
먼저, 아우터 패널(11)과 인너패널(12)에 의해 폐단면을 이루는 도어에 알루미늄 재질로 압출 성형된 H형 단면의 도어 임팩트 빔(20)을 위치시킨다.First, the door impact beam 20 of the H-shaped cross section extruded from an aluminum material is placed on a door that forms a closed cross section by the outer panel 11 and the inner panel 12.
즉, 상기 아우터 패널(11)의 후방에 도어 임팩트 빔(20)을 위치시킨 후, 상기 도어 임팩트 빔(20)의 전후방을 인너패널(12)에 결합시킨다.That is, after the door impact beam 20 is positioned behind the outer panel 11, the front and rear sides of the door impact beam 20 are coupled to the inner panel 12.
이때, 상기 도어 임팩트 빔(20)의 전후방에는 각각 수평면(21)과 제 1 및 제 2 수직면(22)(23)이 연장되어 있는 바,At this time, the horizontal surface 21 and the first and second vertical surfaces 22 and 23 extend in front and rear of the door impact beam 20, respectively.
상기 수평면(21)은 인너패널(12)의 외측면에 결합되고, 상기 제 1 및 제 2 수직면(22)(23)은 인너패널(12)의 수직면에 취부되면서 상기 수평면(21)과 함께 박스단면을 이루게 된다.The horizontal surface 21 is coupled to an outer surface of the inner panel 12, and the first and second vertical surfaces 22 and 23 are mounted on the vertical surface of the inner panel 12, together with the horizontal surface 21. A cross section is formed.
따라서, 상기와 같이 결합되는 도어 임팩트 빔(20)에 의해 차량의 측면 충돌이 발생할 경우, 상기 도어 임팩트 빔(20)은 측면 충돌로부터 발생되는 에너지를 효과적으로 흡수함은 물론, 도어의 실내 밀림량을 최소화시킬 수 있게 되는 것이다.Therefore, when the side impact of the vehicle is caused by the door impact beam 20 coupled as described above, the door impact beam 20 effectively absorbs the energy generated from the side collision, and also controls the amount of indoor sliding of the door. It can be minimized.
한편, 도 7은 본 발명의 다른실시예로, 이는 아우터 패널(11)의 후방에 도어 임팩트 빔(20)에 의해 밀착되는 압축패딩(30)을 적용시킨 것을 도시하고 있다.On the other hand, Figure 7 is another embodiment of the present invention, which shows that the compression padding 30 is applied to the rear of the outer panel 11 in close contact with the door impact beam 20.
즉, 본 발명의 다른실시예에서는, 차량의 측면 충돌시 발생되는 충돌에너지의 흡수량을 보다 극대화시킬 수 있도록 한 것이다.That is, in another embodiment of the present invention, it is possible to maximize the amount of collision energy absorbed when the side impact of the vehicle.
여기서, 상기 압축패딩(30)은 고밀도 스치로폼으로 구성함이 바람직하지만, 반드시 이러한 것에 한정하는 것은 아니다.Here, the compression padding 30 is preferably composed of high density styrofoam, but is not necessarily limited thereto.
이상에서 설명한 바와같이 본 발명은 H형의 단면을 가지면서 전후방으로는 수평면과 수직면이 연장 구성된 도어 임팩트 빔 구조를 적용함으로써, 차량의 측면 충돌시 에너지 흡수율을 극대화함은 물론 도어의 실내 밀림량은 최소화하여 탑승자의 골반부 상해를 저감시킬 수 있도록 하고, 더불어 종래 적용되었던 장착브라켓의 삭제로 부품수 및 작업 공정의 단축을 통해 제조원가를 절감하는 효과를 제공한다.As described above, the present invention has a H-shaped cross section, and by applying a door impact beam structure extending horizontally and vertically in the front and rear, maximizing the energy absorption rate during the side impact of the vehicle, as well as the amount of indoor sliding of the door. By minimizing to reduce the pelvic injury of the occupants, and by eliminating the mounting bracket used in the prior art it provides an effect of reducing the manufacturing cost through the reduction of the number of parts and work process.
