제2도는 본 고안에 따른 자동차프론트 필러 어퍼멤버의 충격흡수구조를 보이는 단면도로서, 이에 도시된 바와 같이 펜더 에이프런 어퍼멤버(30)이 후단부에 복수의 장공(32)(33)을 형성하고, 그 장공(32)(33)을 관통하는 복수의 볼트(34)(35)를 프론트 필러 어퍼멤버(36)에 설치하되 그 볼트(34)(35)와 장공(32)(33)의 전방측 단부가 소정간격(G1)(G2)을 이루도록 구성하였다.2 is a cross-sectional view showing the shock absorbing structure of the automobile front pillar upper member according to the present invention, as shown in the fender apron upper member 30 to form a plurality of long holes (32, 33) at the rear end, A plurality of bolts 34 and 35 penetrating the long holes 32 and 33 are installed in the front pillar upper member 36, and the bolts 34 and 35 and the front sides of the long holes 32 and 33 are installed. The end part was comprised so that the predetermined space | interval G1 (G2) may be made.

한편, 상기 볼트가 차량 주행시 노면의로부터 전달되는 진동 및 충격에 의하여 풀림이 방지되는 것은 체결하는 물품과 너트의 사이에는 너트 및 볼트(34)(35)의 풀림을 방지하는 와셔를 삽설하는 것이 통상적으로 사용되는 방법이며 더 나아가 너트를 볼트에 용접에 의한 접합방법을 사용하여 고정하는 방식 등이 있다.On the other hand, the bolt is prevented from loosening due to the vibration and shock transmitted from the road surface when the vehicle is running, it is common to insert a washer to prevent the loosening of the nut and bolts 34 and 35 between the article and the nut to be fastened. And the method of fixing the nut to the bolt using a welding method by welding.

그러나 본 고안에서는 통상적으로 자동차에서 주되게 사용되는 와셔를 설치하는 방법을 채택하여 사용하며, 상기 와셔는 금속성과 고무재가 통상적으로 사용된다.However, the present invention adopts and uses a method of installing a washer, which is usually used in automobiles, and the washer is generally used with a metal and a rubber material.

상기 펜더 에이프런 어퍼멤버(30)에 여러줄의 수직비드(40)(41)(42)를 일정한 간격으로 형성하여 충돌사고시에 이 부분에서 어코디언 변형을 유도할 수 있도록 구성하였다.The fender apron upper member (30) was formed so that a plurality of vertical beads (40, 41, 42) at regular intervals to induce accordion deformation in this part in the event of a crash.

도면중 미설명 부호 50은 프론트 필러 로워멤버를 나타낸 것이고, 51은 서브프레임을 나타낸 것이다.In the figure, reference numeral 50 denotes a front pillar lower member, and 51 denotes a subframe.

이하 본 고안에 따른 작용을 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, the operation according to the present invention will be described in detail with reference to the accompanying drawings.

먼저, 첨부도면 제2도에 도시된 바와 같이 차량을 정면충돌을 일으키면서 차체의 앞부분이 후방측을 향해 충격을 받게 되면서 펜더 에이프런 어퍼멤버(30)가 도면중 화살표 K방향으로 힘을 받게 되면, 볼트(34)(35)에 의해 프론트 필러 어퍼멤버(36)에 밀착되어 있는 펜더 에이프런 어퍼멤버(30)가 장공 (32)(33)과 볼트(34)(35)의 안내를 받으면서 후방측으로 슬라이딩 된다.First, as shown in FIG. 2, when the front part of the vehicle body is impacted toward the rear side while causing a frontal collision of the vehicle, the fender apron upper member 30 receives the force in the direction of arrow K in the drawing. The fender apron upper member 30, which is in close contact with the front pillar upper member 36 by the bolts 34 and 35, slides to the rear side while being guided by the long holes 32 and 33 and the bolts 34 and 35. do.

이때 볼트(34)(35)와 장공(32)(33)의 사이에는 소정간격(G1)(G2)이 형성되어 이으므로, 이 동안 차체의 변형이 자연됨은 물론, 충격에너지가 차체의 여러곳으로 전파되면서 프론트 필러 어퍼멤버(36)에 집중되는 충격을 감소시켜 주게 된다.At this time, since the predetermined interval (G1) (G2) is formed between the bolts 34, 35 and the long holes 32, 33, during this time, the deformation of the vehicle body is natural, as well as the impact energy of various places of the vehicle body As it propagates to the front pillars to reduce the impact concentrated on the upper member (36).

이를 좀더 구체적으로 설명하면 상기 차량의 충돌시 임팩트되는 힘은 순간적으로 큰 힘이 작용되며 차량의 운행시 노면의 상태에 따라 차체에 전달되는 진동은 상대적으로 작은 힘이 작용된다.In more detail, when the impact of the vehicle impacts a large force is applied momentarily, the vibration transmitted to the vehicle body according to the state of the road surface during the operation of the vehicle relatively small force is applied.

상기한 차체에 작용되는 힘의 크기를 살펴보면 진동에 의해 전달되는 충격 < 펜더 에이프런 어퍼멤버(30)와 프론트 필러 어퍼멤버(36)의 체결력 < 임팩트시 충격과 같이 힘의 균형이 작용되기 때문에 볼트가 차량의 운행시 풀림이 억제되어 있는 상태이며, 차체의 변형이 자연됨은 물론, 충격에너지가 차체의 여러곳으로 전파되면서 프론트 필러 어퍼멤버(36)에 집중되는 충격을 감소시켜 주게 된다.When considering the magnitude of the force applied to the vehicle body, the shock <transmitted by vibration <bolts are applied because the force is acted as a force <the fastening force of the fender apron upper member 30 and the front pillar upper member 36 <impact When the vehicle is running, the loosening is suppressed, and the deformation of the vehicle body is natural, and as the impact energy propagates to various places of the vehicle body, the impact concentrated on the front pillar upper member 36 is reduced.

이상에서 설명한 바와 같이 본 고안은 펜더 에이프런 어퍼멤버와 프론트 필러 어퍼멤버의 연결부위에 위치되는 장공 및 볼트를 이용하여 차량의 정면 충돌시에 후방측으로 밀리는 펜더 에이프런 어퍼멤버 및 프론트 필러 어퍼멤버의 변형속도를 늦추는 동시에 충격에너지를 감소시킬수 있도록 구성되어 있으므로, 종래의 것보다 자체의 실내침입속도 및 실내침입량을 감소 시키는 동시에 인체상해치를 크게 낮출 수 있는 효과가 있다.As described above, the present invention uses a long hole and a bolt located at the connection portion between the fender apron upper member and the front pillar upper member, so that the deformation speed of the fender apron upper member and the front pillar upper member that is pushed to the rear side during the frontal collision of the vehicle. Since it is configured to reduce the impact energy at the same time, it has the effect of significantly reducing the body intrusion rate and room intrusion amount at the same time as compared to the conventional one can significantly lower the human injury.
