본 고안은 차량의 도어내측에 설치되어 차량이 충돌사고시 도어의 함몰과 파손으로 인한 피해를 최소화 시킬 수 있도록 하는 임펙트멤버(Impact member)에 관한 것으로써, 특히 충돌로 인하여 차량의 실내로 진입되는 임펙트멤버의 충격력을 완충 저지시켜 탑승자의 피해를 최소화 할 수 있도록 하는 차량도어용 임펙트멤버 완충장치를 제공하기 위한 것이다.The present invention relates to an impact member installed inside the door of the vehicle so that the vehicle can minimize the damage caused by the depression and damage of the door in the event of a collision. In particular, the impact that enters the interior of the vehicle due to a collision It is to provide a shock member shock absorber for a vehicle door that minimizes the impact of the member 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, 외부로 부터 도어에 충격이 가해질때 도어의 패널이 변형되면서 차체내부로 진입되는 것을 최소화시킬 수 있도록 하는 임펙트멤버를 설치하는 것이 보편적이다.As an example of a means to solve this problem, it is common to install an impact member that can 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 임펙트멤버가 갖추어야 할 조건으로는 충격흡수력과 인장강도가 커야만하는데 이는 측면 충돌시 뛰어난 완충작용과 도어패널의 변형에 따른 실내진입을 최소화 하여 탑승자를 보호할 수 있기 때문이다.Impact conditions and tensile strength must be large as a condition that the impact member must be as described above, because it is possible to protect the occupants by minimizing the entry into the room due to the excellent buffering action and deformation of the door panel during side impact.

종래에 있어서의 임펙트멤버 설치구조는 첨부된 도면 제2도에 도시된 바와 같이, 차량의 측면도어(2) 내부에 설치되는 임펙트멤버(2)의 단순히 아웃도어에 부착설치되어 도어의 보강부재의 역할만을 수행하는 것으로서 이와같은 임펙트멤버(2)는 자체적으로 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 member mounting structure, as shown in FIG. 2 of the accompanying drawings, it is simply attached to the outdoor of the impact member 2 installed inside the side door 2 of the vehicle, The impact member 2 does not have a large stress on its own as it only plays a role and is easily deformed together with the door panel in the event of a side collision of the vehicle. .

따라서 본 고안은 상기한 바와같은 종래의 문제점을 해결하기 위한 것으로써, 본 고안의 목적은 차량의 충돌사고에 의하여 도어패널과 함께 실내로 진입하는 임펙트멤버를 저지시키면서 그 충격력을 흡수 완충시켜서 차량 피해는 물론 탑승자의 피해를 최소화할 수 있도록 하는 차량용 임펙트멤버 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 member to enter the room with the door panel due to the collision of the vehicle absorbs and absorbs the impact force to damage the vehicle Of course, to provide an impact member buffer for the vehicle to minimize the damage of the occupants.

상기와 같은 목적을 달성하기 위한 본 고안은 도어측면패널에 양단부가 결합되어 설치된 임펙트멤버와 도어인너패널사이에 충돌사고에 의하여 실내로 진입되는 임펙트멤버의 충격력을 다단계로 흡수 완충저지시키는 충격흡수장치를 개재시킨 것에 특징을 둔 것인바, 이를 첨부된 도면에 의하여 보다 상세하게 설명하면 다음과 같다.The present invention for achieving the above object is a shock absorbing device for absorbing and buffering the impact force of the impact member entered into the room by a multi-step impact between the impact member and the door inner panel is installed coupled to both ends of the door side panel in multiple stages It is characterized by the intervening bar, which will be described in more detail by the accompanying drawings as follows.

첨부된 도면 제1도에 도시된 바와 같이, 차량의 측면도어(1) 내부에 설치되어 대차의 충돌력에 대응하는 임펙트멤버(2)에 있어서, 상기 임펙트멤버(2)와 대향되는 도어인너패넬(11)사이에 충돌력에 의하여 실내로 진입되는 임펙트멤버(2)의 충격력을 흡수완충시켜 실내진입을 저지하는 완충장치(3)를 개재시켜 구성되는 것으로, 상기 완충장치(3)는 도어인너패널(11)에 고정결합되는 결합부(30)의 양단이 절곡되어 측벽(31)을 형성시키고, 각 측벽(31)의 선단부는 외측방으로 원호형을 이루어 진입되는 멤버가 용이하게 삽입될 수 있도록 확개부(32)를 형성시키며 상기 각 측벽(31)의 중앙부위에는 진입되는 임펙트멤버(2)의 충격력을 흡수완충시키는 절곡부(33)를 형성시켜 구성된 것이다.As shown in FIG. 1, in the impact member 2 installed inside the side door 1 of the vehicle and corresponding to the collision force of the vehicle, the door inner panel is opposed to the impact member 2. The shock absorber 3 is configured to intervene with a shock absorber 3 for absorbing and buffering the impact force of the impact member 2 that enters the room by the collision force, thereby preventing the entry of the room. Both ends of the coupling part 30 fixedly coupled to the panel 11 may be bent to form the side walls 31, and the front end portions of the respective side walls 31 may be easily inserted to form an arc to the outside. It is formed by forming a bent portion 33 so as to form an expansion portion 32 and absorbs and buffers the impact force of the impact member (2) to enter the central portion of each side wall (31).

이와같이 구성되는 본 고안의 작용과 그 효과를 설명하면 다음과 같다. 대차에 의한 충돌력으로 실내로 진입하려는 임펙트멤버(2)가 외측방으로 원호를 이루며 펼처진 확개부의 내부로 압착삽입되면서 각 측벽의 탄성력에 의하여 1차로 충격력이 흡수완충되고 이어지는 진입동작에 의하여 측벽에 형성된 절곡부가 외측으로 절곡변형되면서 멤버의 선단이 절곡부의 모서리부와 접하여 지면서 진입동작을 저지받게 된다. 이어 계속되는 임펙트멤버의 진입동작으로 측벽의 후단부도 외측으로 절곡변형되면서 2차로 충격력을 흡수 완충시키게 되어 임펙트멤버(2)가 도어인너패널(11)에 접촉되는 시점에서는 임펙트멤버(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. The impact member (2) attempting to enter the room by the collision force by the bogie forms a circular arc to the outside and press-inserts it into the unfolded extension part. As the bent portion is formed to bend to the outside and the front end of the member is in contact with the corner of the bent portion is inhibited the entry operation. Subsequently, the rear end portion of the side wall is also bent and deformed to the outside as the impact member 2 continuously absorbs and absorbs and cushions the impact force so that the impact member 2 is retained when the impact member 2 contacts the door inner panel 11. The impact force is very weak to reduce the damage of the occupants.

이상에서와 같이 본 고안에 따른 임펙트멤버 완충장치에 의하면, 대차의 충돌력에 의하여 실내로 진입하는 임펙트멤버의 충돌력을 다단계로 흡수 완충시켜 탑승자의 피해를 최소화 시킴은 물론 차량의 피해 또한 최소화시킬 수 있는 효과가 있는 것이다.According to the impact member buffer device according to the present invention as described above, by absorbing and cushioning the impact force of the impact member 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.
