본 고안은 차량의 도어내측에 설치되어 차량의 충돌사고시 도어의 함몰과 파손으로 인한 피해를 최소화 시킬 수 있도록 하는 임펙트바(Impact bar)에 관한 것으로써, 특히 충돌로 인하여 차량의 실내로 진입되는 임펙트바의 충격력을 완충저지시켜 탑승자의 피해를 최소화할 수 있도록 하는 차량도어용 임펙트바 완충장치를 제공하기 위한 것이다.The present invention relates to an impact bar installed inside the door of the vehicle to minimize the damage caused by the depression and damage of the door in the event of a collision of the vehicle. In particular, the impact that enters the interior of the vehicle due to the collision It is to provide an impact bar shock absorber for a vehicle door that buffers the impact force of the bar to minimize the damage of the occupants.
일반적으로 차량의 전후방에는 충돌에 대한 충격저감수단으로 완충부재인 범퍼가 설치되는데 반하여 차량의 측면충돌에 대한 저감수단은 구비되어있지 않기 때문에 측면 충돌시 탑승자를 보호할 수 없는 것이 문제점으로 지적되고 있다.Generally, bumpers, which are cushioning members, are installed in the front and rear of the vehicle as a shock reduction means for impacts. However, there is no reduction means for the side collision of the vehicle. .
이러한 문제점을 해결하기 위한 수단의 일예로서, 외부로부터 도어에 충격이 가해질때 도어의 패널이 변형되면서 차체내부로 진입되는 것을 최소화 시킬 수 있도록 임펙트바를 설치하는 것이 보편적이다.As an example of a means for solving such a problem, it is common to install an impact bar so as to minimize the entry of the inside of the vehicle body while the panel of the door is deformed when the door is impacted from the outside.
상기한 바와 같은 임펙트바가 갖추어야 할 조건으로는 충격흡수력과 인장강도가 커야만하는데 이는 측면 충돌시 뛰어난 완충작용과 도어패널의 변형에 따른 실내진입을 최소화 하여 탑승자를 보호할 수 있기 때문이다.The impact bar must have a high impact absorbing force and tensile strength as described above, because it can protect the occupants by minimizing the entry of the interior due to the deformation of the door panel and the excellent cushioning action during side impact.
종래에 있어서의 임펙트바 설치구조는 첨부된 도면 제2도에 도시된 바와같이, 차량의 측면도어(1) 내부에 설치되는 임펙트바(2)의 양단부만이 도어측면판넬에 결합되어 설치되는 구조로써, 이와같이 임펙트바(2)의 양단부만이 지지결합되는 종래의 임펙트바(2) 설치구조는 길이재인 임펙트(2)가 큰 응력을 보유하지 못하게 되어 차량의 측면충돌 사고시 도어패널과 함께 쉽게 변형되면서 실내로 진입되어 탑승자의 안전을 보장하지 못하게 되는 문제점이 있는 것이다.In the conventional impact bar installation structure, as shown in FIG. 2, only two ends of the impact bar 2 installed inside the side door 1 of the vehicle are coupled to the door side panel. As such, the conventional impact bar (2) installation structure in which only the both ends of the impact bar (2) is supported is deformed so that the impact (2), which is a length member, does not hold a large stress, and is easily deformed together with the door panel in case of a side collision of the vehicle. While entering the interior there is a problem that does not guarantee the safety of the occupants.
따라서 본 고안은 상기한 바와 같은 종래의 문제점을 해결하기 위한 것으로써, 본 고안의 목적은 차량의 충돌사고에 의하여 도어패널과 함께 실내로 진입하는 임펙트바를 저지시키면서 그 충격력을 흡수 완충시켜켜 차량 피해는 물론 탑승자의 피해를 최소화할 수 있도록 차량용 임펙트바 완충장치를 제공하기 위한 것이다.Therefore, the present invention is to solve the conventional problems as described above, the object of the present invention is to prevent the impact by absorbing the shock force while preventing the impact bar entering the room with the door panel due to the collision of the vehicle damage to the vehicle Of course, to provide a vehicle impact bar shock absorber to minimize the damage of the occupants.
상기와 같은 목적을 달성하기 위한 본 고안은 도어측면패널에 양단부에 결합되어 설치된 임펙트바와 대향되는 도어인너패널에 충돌사고에 의하여 실내로 진입되는 임펙트바의 충격력을 흡수 완충저지시키는 충격흡수장치를 설치시킨 것에 특징을 둔 것인바, 이를 첨부된 도면에 의하여 보다 상세하게 설명하면 다음과 같다.The present invention for achieving the above object is installed a shock absorbing device for absorbing and buffering the impact force of the impact bar entering the room by a collision accident in the door inner panel opposite to the impact bar is installed coupled to both ends of the door side panel It is characterized in that the bar, described in more detail by the accompanying drawings as follows.
첨부된 도면 제1도에 도시된 바와같이, 차량의 측면도어(1) 내부에 설치되어 대차의 충돌격에 대응하는 임펙트바(2)에 있어서, 상기 임펙트(2)와 대향되는 도어인너패널(11)에 충돌력에 의하여 실내로 진입되는 임펙트바(2)의 충격력을 흡수완충시켜 실내진입을 저지하는 완충장치(3)를 설치시켜 구성되는 것으로, 상기 완충장치(3)는 임펙트바(2)와 최초로 접촉하는 돌출부(31a)를 가지며 도어인너패널(11)과 결합되는 제1완충부(31)와, 상기 제1완충부(31)의 내측에 상기 돌출부(31a)와 대응되도록 요홈형상으로 형성되어 제1완충부(31)를 보강시키는 보강판(35)과, 상기 보강판(35)의 양측에 보강판을 지지하는 지지체(36)가 결합되며, 지지체(36)에는 지지체를 받추어주는 지지판(38)이 결합설치되며, 상기 지지판(38)의 일단은 제1완충부(31)의 측벽에 결합되고 또다른 일단은 제1완충부(31)와 동일한 형상으로 형성되는 제2완충부(32)와 결합되어 구성되는 것이다.As shown in FIG. 1 of the accompanying drawings, in the impact bar 2 installed in the side door 1 of the vehicle and corresponding to the collision gap of the vehicle, the door inner panel facing the impact 2 ( 11) is configured to install a shock absorber (3) to prevent the entry of the room by absorbing and buffering the impact force of the impact bar (2) entering the room by the impact force, the shock absorber (3) is an impact bar (2) ) Has a protrusion (31a) for the first contact with the first shock absorbing portion (31) coupled to the door inner panel 11, and the groove shape so as to correspond to the protrusion (31a) inside the first shock absorbing portion (31). Reinforcement plate 35 is formed to reinforce the first buffer part 31 and the support body 36 for supporting the reinforcement plate on both sides of the reinforcement plate 35 is coupled, the support body 36 receives the support A support plate 38 is provided for coupling, and one end of the support plate 38 is coupled to the side wall of the first buffer part 31, and another Stage is constituted in combination with a second buffer part 32 is formed in the same shape as the first buffer unit (31).
이와같이 구성되는 본 고안의 작용과 그 효과를 설명하면 다음과 같다. 대차에 의한 충돌력으로 실내로 진입되는 임펙트바(2)가 제1완충부(31)의 돌출부(31a)와 접촉하여 돌출부가 함몰변형되면서 충격력이 흡수완충되어 그 진입이 1차 저지되고 계속되는 충격력에 의하여 제1완충부(31)의 돌출부(31a)가 보강판(35)을 압박함에 따라 보강판(35)을 지지하는 지지체(36)가 절곡변형되면서 임펙트바(2)의 충격력을 2차로 흡수 완충시키게 된다. 이어 계속되는 임펙트바(2)의 진입에 의하여 보강판(35)이 제2완충부(32)와 접촉되어 제2완충부(32)의 돌출부(32a)가 함몰 변형되면서 3차로 충격력을 흡수 완충시켜 임펙트바(2)가 도어인너패널(11)에 접촉되는 시점에서는 임펙트바(2)가 보유하는 충격력이 매우 약하게 되어 탑승자의 피해를 줄일 수 있게 되는 것이다.Referring to the operation of the present invention and the effects configured as described above are as follows. Impact bar (2) entering the room by the impact force of the trolley is in contact with the protrusion (31a) of the first shock absorbing portion 31, the protrusion is deformed and the impact force is absorbed and buffered, the entry is first blocked and the impact force continues As the protrusion 31a of the first shock absorbing portion 31 presses the reinforcing plate 35, the support 36 supporting the reinforcing plate 35 is bent and deformed, thereby secondarily impacting the impact bar 2. Absorption buffer. Subsequently, the reinforcing plate 35 is contacted with the second shock absorbing portion 32 by the continuous entry of the impact bar 2, and the protrusion 32a of the second shock absorbing portion 32 is depressed, thereby absorbing and buffering the impact force in a third manner. When the impact bar 2 is in contact with the door inner panel 11, the impact force held by the impact bar 2 becomes very weak to reduce the damage of the occupant.
이상에서와 같이 본 고안에 따른 임펙트바 완충장치에 의하면, 대차의 충돌력에 의하여 실내로 진입하는 임펙트바의 충돌력을 다단계로 흡수 완충시켜 탑승자의 패해를 최소화 시킴은 물론 차량의 피해 또한 최소화시킬 수 있는 효과가 있는 것이다.According to the impact bar shock absorber according to the present invention as described above, by absorbing and cushioning the impact force of the impact bar entering the room by the impact force of the vehicle in multiple stages to minimize the damage of the occupants as well as to minimize the damage of the vehicle. It can be effective.
