본 고안은 자동차의 사이드실(SIDE SILL)구조에 관한 것으로, 더 상세하게는 자동차의 측면 충돌시 사이드실의 전방부에서 충분한 충격흡수를 수행할 수 있도록 함과 동시에 후방부의 센터플로워패널과의 결합강성을 증대시켜, 실내의 승객에 전달되는 충격량을 최대한 줄일 수 있도록 한 것이다.The present invention relates to a side seal structure of a vehicle, and more particularly, to provide sufficient shock absorption at the front of the side chamber in the event of a side collision of the vehicle, and to be combined with the center follower panel at the rear. By increasing the rigidity, it is possible to reduce the amount of impact transmitted to the passengers in the room as much as possible.

일반적으로 자동차의 충돌사고시 승객의 안전을 확보하기 위한 테스트로는 전방충돌(FRONT IMPACT)과 측면충돌(SIDE IMPACT)이 있으며, 이는 자동차의 안전성을 확보하는 중요한 요소로서 이미 세계 각 나라에서는 이러한 충돌시의 안전치를 법규화하여 수입규제등의 큰 항목으로 이용되고 있다.In general, tests to ensure the safety of passengers in the event of a car crash include FRONT IMPACT and SIDE IMPACT, which are important factors to ensure the safety of the car. Has been used as a large item such as import regulation by legalizing the safety level.

그러나, 현재 생산되고 있는 자동차는 대부분이 전방충돌에 대핸 안전치는 어느 정도 확보하고 있으나, 측면충돌에 대한 안전치는 미흡한 실정이다. 즉, 그 원인으로는 제1도에 도시한 차체의 사이드실 구조가 취약하기 때문이며, 실제로 타차량과의 측면충돌시, 외부로 부터 이중충돌벽(MOVING DEFORMABLE BARRIER ; 통상 MDB라 약칭함)이 충돌해 왔을때의 시험조건을 적용할때, 사이드실 부분이 실내로 밀리면서 센터필러, 도어, 루프상단까지 변형이 오고, 이로 인하여 승객 인체의 상해치중 골반부에 해당하는 펠비스(PELVIS)값이 커지는 문제가 있다.However, most of the cars currently produced have some safety values for forward collisions, but the safety values for side collisions are insufficient. That is because the structure of the side seal of the vehicle body shown in FIG. 1 is weak, and when a side collision with another vehicle actually occurs, a collision collision (MOVING DEFORMABLE BARRIER; commonly abbreviated as MDB) collides from the outside. When the test conditions are applied, the side seal part is pushed into the room, and the center pillar, door, and roof top are deformed, which causes the PELVIS value corresponding to the pelvis of the injury of the passenger's body to increase. There is.

종래 사이드실 구조는 제2도에 도시된 바와같이 센터플로워패널(1)의 외측으로 사이드실인너패널(2)과 사이드실아웃터패널(3)이 보강부재(4)를 사이에 두고 결합되어 사이드실 박스(10)를 구성한다.In the conventional side seal structure, as shown in FIG. 2, the side seal inner panel 2 and the side seal outer panel 3 are coupled to the outside of the center follower panel 1 with the reinforcing member 4 interposed therebetween. The seal box 10 is configured.

따라서, 이와같이 구성된 종래의 사이드실 구조는 그 지지기반이 매우 취약하기 때문에 차량의 측면 충돌시 사이드실의 전방부에서 충분한 충격흡수가 되지 않고, 또한 후방부의 센터플로워패널(1)과의 결합강성이 유지되지 않기 때문에 이로 인하여 상기 각각의 패널(1)(2)(3)과 보강부재(4)가 실내로 밀리게 되므로 센터필러와 도어 및 루프 상단까지 변형이 초래되어 인체상해 중 골반부에 해당하는 펠비스값이 좋지 않은 문제가 있었다.Therefore, the conventional side seal structure configured as described above is very weak in its support base, so that the front side of the side seal does not have sufficient shock absorption in the side collision of the vehicle, and the coupling rigidity with the center follower panel 1 in the rear portion is not sufficient. Because of this, each panel 1, 2, 3 and reinforcing member 4 are pushed into the room, which causes deformation to the center pillar, the top of the door and the roof, which corresponds to the pelvic part of the human injury. There was a problem that the Pelvis value was not good.

본 고안의 목적은 상기에서와 같은 종래의 문제점을 해소하기 위해 안출된 것으로, 자동차의 측면 충돌시 사이드실의 전방부에서 충분한 충격흡수를 수행할 수 있도록 함과 동시에 후방부의 센터플로워패널과의 결합강성을 증대시켜, 실내에 전달되는 충격량을 최대한 줄일 수 있도록 한 자동차의 사이드실 구조를 제공하는 데 있다.The object of the present invention is to solve the conventional problems as described above, in the event of a side collision of the vehicle to perform a sufficient shock absorption in the front of the side chamber and at the same time combined with the center follower panel of the rear In order to increase the rigidity, and to reduce the amount of impact transmitted to the interior as much as possible to provide a vehicle side seal structure.

상기의 목적을 달성하기 위한 본 고안은, 센터플로워패널의 외측으로 사이드실아웃터패널과 사이드실인너패널이 보강부재를 사이에 두고 결합되어 사이드실박스를 구성한 것에 있어서, 사이드실박스의 상단결합부에 제2보강부재의 상단이 결합되고 제2보강부재는 사이드실인너패널과 적당한 공간부를 두고 그 하단이 센터플워패널의 윗면에 결합고정되며, 공간부의 하단에 제3보강부재를 설치하되, 이 제3보강부재의 하단은 사이드실박스의 하단부에 함께 결합되면서 사이드실인너패널의 측면에 밀착되고 상단은 내측으로 절곡되어 제2보강부재의 측벽에 밀착되채 제2보강부재의 하단과 함께 결합고정되어 충격흡수공간을 극대화 시킨 것을 특징으로 한다.The present invention for achieving the above object, the side seal outer panel and the side seal inner panel is coupled to the outer side of the center follower panel with a reinforcing member interposed between the upper seal portion of the side seal box, The upper end of the second reinforcing member is coupled, the second reinforcing member has a side seal inner panel and a suitable space portion, and the bottom thereof is fixed to the upper surface of the center flower panel, and the third reinforcing member is installed at the bottom of the space portion. The lower end of the third reinforcing member is coupled to the lower end of the side seal box while being in close contact with the side of the side seal inner panel, and the upper end is bent inward to be in close contact with the side wall of the second reinforcing member and fixed together with the lower end of the second reinforcing member. It is characterized by maximizing the shock absorption space.

이하 첨부된 도면을 따라서 본 고안의 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration of the present invention in detail according to the accompanying drawings.

본 고안은 제3도에 도시한 바와같이 센터플로워패널(11)의 외측으로 사이드실아웃터패널(13)과 사이드실인너패널(12)이 보강부재(14)를 사이에 두고 결합되어 사이드실박스(20)를 구성한다.According to the present invention, as shown in FIG. 3, the side seal outer panel 13 and the side seal inner panel 12 are coupled to the outside of the center follower panel 11 with the reinforcing member 14 interposed therebetween. It constitutes 20.

이 사이드실박스(20)의 상단결합부에는 제2보강부재(15)의 상단이 스폿(SPOT)용접에 의해 고정되어 있는바, 이 제2보강부재(15)는 사이드실인너패널(12)과 적당한 공간부(16)를 두고 그 하단이 센터플로워패널(11)의 윗면에 용접되어 결합고정된다.The upper end of the second reinforcing member 15 is fixed to the upper engaging portion of the side seal box 20 by spot welding, and the second reinforcing member 15 is the side seal inner panel 12. With the appropriate space portion 16 and the lower end is welded and fixed to the upper surface of the center follower panel (11).

또한 공간부(16)의 하단에는 제3보강부재(17)가 설치되는데, 이 제3보강부재(17)의 하단은 사이드실박스(20)하단 결합부에 함께 용접 결합되면서 사이드실인너패널(12)의 측면에 밀착되어 있고 상단은 내측으로 절곡되어 제2보강부재(15)의 측벽에 밀착된채 제2보강부재(15)의 하단과 함께 결합고정되어 충격흡수공간을 극대화시키도록 되어 있다.In addition, a third reinforcing member 17 is installed at the lower end of the space part 16, and the lower end of the third reinforcing member 17 is welded together to the lower coupling part of the side seal box 20 while the side seal inner panel ( 12) is in close contact with the upper end is bent to the inside of the second reinforcing member (15) while being fixed to the side of the second reinforcing member (15) in close contact with the bottom of the second reinforcing member (15) to maximize the impact absorption space. .

이와같이 구성된 본 고안은 차량의 측면충돌시 사이드실박스(20)의 사이드실아웃터패널(13)이 먼저 충돌하면서 일차적으로 어느정도의 충격을 흡수하게 되고 이어서 나머지 충격은 보강부재(14) 및 사이드실인너패널(12)이 밀리면서 더욱 흡수되며 아울러 제2보강부재(15)와 제3보강부재(17)가 밀리면서 공간부(16)가 축소됨에 따라 그 충격력은 더욱 완화, 흡수된다.The present invention configured as described above has a side seal outer panel 13 of the side seal box 20 when the side impact of the vehicle collides first to absorb a certain amount of impact and then the remaining impact is the reinforcing member 14 and the side seal inner As the panel 12 is pushed and further absorbed, and the second reinforcing member 15 and the third reinforcing member 17 are pushed and the space 16 is reduced, the impact force is further alleviated and absorbed.

또한 제3보강부재(17)는 외부의 충격흡수 뿐아니라 사이드실박스(20)와 센터플로워패널(11)과의 결합강성을 증대시켜 하량의 측면충돌시 사이드실박스(20)가 실내로 밀리지 않게 함과 동시에 변형을 방지한다.In addition, the third reinforcing member 17 increases the coupling stiffness between the side seal box 20 and the center follower panel 11 as well as the external shock absorption, so that the side seal box 20 is pushed into the room during side impact of the load. And at the same time prevent deformation.

따라서, 이러한 본 고안은 외부로 부터의 충격이 제2,제3보강부재(15)(17)의 공간부(16)가 축소되면서 흡수,완화되므로 센터필러와 도어 및 루르의 변형이 방지되고, 인체상해 중 골반부에 해당하는 펠비스값이 감소되는 장점이 있다.Therefore, the present invention is absorbed and alleviated as the impact from the outside is reduced, the space portion 16 of the second, third reinforcing members (15) and (17) is prevented from deformation of the center pillar, the door and ruhr, Pelvis value corresponding to the pelvis of human injury is reduced.

이상에서 설명한 바와 같이 본 고안은 사이드실박스의 사이드실인너패널(12)측으로 공간부를 갖는 제2,3보강부재를 고정설치하므로 충격 흡수공간을 극대화시켜 외부의 충격을 흡수, 완화시킴은 물론 사이드실박스와 센터플로워패널과의 결합강성을 증대시켜 완충과 보강효과가 향상되도록 한 매우 유용한 고안이다.As described above, the present invention fixedly installs the second and third reinforcing members having a space toward the side seal inner panel 12 side of the side seal box, thereby maximizing the shock absorbing space to absorb and mitigate external shocks, as well as the side. It is a very useful design to improve the cushioning and reinforcing effect by increasing the bonding rigidity between the seal box and the center follower panel.
