본 고안은 자동차의 센터플로워와 사이드실(SIDE SILL)의 결합 구조에 관한 것으로, 더 상세하게는 자동차의 측면충돌시 사이드실의 전방부에서 충분한 충격흡수를 수행할 수 있도록 함과 동시에, 후방부의 센터플로워와의 결합강성을 증대시켜 실내의 승객에 전달되는 충격량을 최대한 줄일 수 있도록 한 것이다.The present invention relates to a combination structure of the center floor of the vehicle and the side seal, and more particularly, to provide sufficient shock absorption at the front of the side seal during side collision of the vehicle, By increasing the rigidity with the center follower 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 각 나라에서는 이러한 충돌시의 안전치를 법규화하여 수입규제등의 큰 항목으로 이용되고 있다.In general, the 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. It is used as a large item such as import regulation by legalizing safety value.

그러나, 현재 사용되고 있는 자동차는 대부분 전방충돌에 대한 안전치는 어느 정도 확보하고 있으나, 측면충돌에 대한 안전치는 미흡한 실정이다. 즉, 그 원인으로는 차체의 사이드실 구조가 취약하기 때문이며, 실제로 타차량과의 측면충돌시, 본 고안에서는 외부로 부터 이중충돌벽(MOVING DEFORMABLE BARRIER ; 통상 MDB라 약칭함 ; 100)이 충돌해 왔을때의 시험조건을 적용할 때, 사이드실 부분이 실내로 밀리면서 센터필러, 도어, 루프상단까지 변형이 오고, 이로 인하여 승객 인체의 상해치중 골반부에 해당하는 펠비스(PELVIS)값이 커지는 문제가 있었다.However, most of the cars currently used have a certain level of safety against frontal collisions, but the safety level against side collisions is insufficient. That is because the structure of the side seal of the vehicle body is weak, and in the case of side collision with other vehicles, in the present invention, a double collision wall (MOVING DEFORMABLE BARRIER; commonly abbreviated as MDB; 100) collides from the outside. When the test conditions are applied, the side seal 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 was.

종래의 센터플로워 및 사이드실의 결합구조는 제2도에 도시된 바와같이 센터플로워패널(1)의 외측으로 사이드실 아웃터패널(3)과 사이드실 인너패널(2)이 보강부재(4)를 사이에 두고 결합되어 사이드실 박스(10)를 구성한다.In the conventional combination of the center follower and the side seal, as shown in FIG. 2, the side seal outer panel 3 and the side seal inner panel 2 are provided with the reinforcing member 4 to the outside of the center follower panel 1. They are coupled to each other to form a side seal box 10.

따라서 이와같이 구성된 종래의 사이드실 구조는 그 지지기반이 매우 취약하므로 차량의 측면 충돌시 사이드실(10)의 전방부에서 충분한 흡수가 되지 않고, 또한 후방부의 센터플로워패널(1)과의 결합강성이 유지되지 않기 때문에 이로 인하여 상기 각각의 패널(1)(2)(3)과 보강부재(4) 등이 실내로 밀리게 되므로써 센터필러와 도어 및 루프 상단까지 변형되어 인체상해중 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 10 is not sufficiently absorbed during side impact of the vehicle, and the coupling rigidity with the center follower panel 1 in the rear part is not sufficient. Because of this, each panel 1, 2, 3 and the reinforcing member 4 are pushed into the room, which deforms to the center pillar, the top of the door and the roof, and the pelvis corresponding to the pelvis during injury. There was a problem that the service value was not good.

본 고안의 목적은 상기에서와 같은 종래의 결정을 해소하기 위해 안출된 것으로, 자동차의 측면 충돌시 사이드실의 전방부에서 충분한 충격흡수를 수행할 수 있도록 함과 동시에 후방부에 센터플로워와 결합강성을 증대시켜, 실내의 승객에 전달되는 충격량을 최대한 줄일 수 있도록 한 자동차의 센터플로워 및 사이드실의 결합구조를 제공하는데 있다.The object of the present invention is to solve the conventional decision as described above, to provide sufficient shock absorption at the front of the side chamber during side collision of the vehicle, and at the same time to the center follower and coupling rigidity In order to reduce the amount of shock transmitted to the passengers in the room, the center floor and side seals of the vehicle are combined to provide a combined structure.

이와같은 목적을 달성하기 위한 본 고안은, 센터플로워패널의 외측으로 사이드실 아웃터패널과 사이드실 인너패널이 보강부재를 사이에 두고 결합되어 사이드실 박스를 구성한 것에 있어서, 센터플로워패널이 사이드실 박스의 내부로 연장되어 상향 절곡된 절곡 성형부를 이루며 그 전반중간에는 비드가 형성되고, 센터플로워의 단부는 사이드실 박스의 상측 연결부와 함께 결합되며, 절곡 성형부의 전방으로 보강부재가 추가로 설치되고, 센터플로워의 하단에 제2 보강부재가 결합 고정되어 사이드실 아웃터패널의 하단이 센터플로워 하측에서 제2 보강부재와 결합됨으로써 충격흡수 및 강성을 증대시킬 수 있도록 된 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 the reinforcing member between the center seal panel, the center follower panel is a side seal box A bead is formed in the first half of the bent forming portion is extended to the inside of the bent, the end of the center follower is coupled with the upper connection of the side seal box, a reinforcing member is further installed in front of the bent forming portion, The second reinforcing member is fixedly coupled to the lower end of the center follower so that the lower end of the side seal outer panel is coupled with the second reinforcing member under the center follower to increase shock absorption and rigidity.

Referring to this, the side seal outer panel 13 and the side inner panel 12 are reinforcing members outside the center follower panel 11. The side seal box 20 is comprised with 14 in between.

센터플로워패널(11)은 사이드실 박스(20) 내부까지 연장 형성되어 상측으로 절곡된 절곡 성형부(15)를 이루고 절곡 성형부(15)의 끝단부는 사이드인너패널(12)과 사이드아웃터패널(13)과 함께 스폿 용접으로 고정되고, 절곡 성형부(15)의 중간에는 내측으로 인입형성되는 비드(16)가 형성된다.The center follower panel 11 extends to the inside of the side seal box 20 to form a bent molding part 15 that is bent upwards, and end portions of the bent molding part 15 are side inner panel 12 and side outer panel ( 13) is fixed by spot welding, a bead 16 is formed in the middle of the bent forming portion 15 to be inwardly formed.

또한 센터플로워패널(11)의 절곡 성형부(15)의 전방으로는 보강부재(14)가 위치되어 양단이 비드(16)의 상하부에서 스폿 용접으로 고정되며, 센터플로워패널(11)의 하단에는 제2 보강부재(17)가 결합 고정된다.In addition, the reinforcing member 14 is positioned in front of the bent forming portion 15 of the center follower panel 11 so that both ends are fixed by spot welding at the upper and lower portions of the bead 16, and at the lower end of the center follower panel 11 The second reinforcing member 17 is fixedly coupled.

제2 보강부재(17)는 양쪽단부가 센터플로워패널(11) 하면과 스폿 용접으로 고정설치되고, 그중 외측단부는 하방으로 절곡 연장 형성되어 사이드실아웃터패널(13)의 한쪽 단부와 결합되어 이루어진다.Both ends of the second reinforcing member 17 are fixed to the bottom of the center follower panel 11 by spot welding, and an outer end of the second reinforcing member 17 is formed to be bent downwardly and coupled to one end of the side seal outer panel 13. .

사이드실 인너패널(12)은 양단부 중 한쪽단부가 센터플로워패널(11)의 절곡 성형부(15) 및 사이드실 아웃터패널(13)과 함께 스폿 용접으로 고정되고, 다른쪽 단부는 제2 보강부재(17)의 내측 단부와 같은 위치에서 센터플로워패널(11)에 스폿 용접으로 고정되며 중간부위는 경사지게 절곡되어 형성된다.In the side seal inner panel 12, one end of both ends is fixed by spot welding together with the bent molding portion 15 and the side seal outer panel 13 of the center follower panel 11, and the other end thereof is the second reinforcing member. It is fixed by spot welding to the center follower panel 11 at the same position as the inner end of 17, and the middle portion is formed by being bent obliquely.

여기서, 판넬강성을 위해 종그루브(11a), 횡그루브(11b)을 구성하였다.Here, longitudinal grooves 11a and lateral grooves 11b were configured for panel rigidity.

이와같이 구성된 본 고안은 차량의 측면충돌시 사이드실 박스(20)의 사이드실 아웃터패널(13)이 먼저 충돌하면서 일차적으로 어느 정도의 충격을 흡수하게 되고, 이어서 나머지 충격은 센터플로워패널(11)의 절곡 성형부(15)전방에 설치된 보강부재(14)가 찌그러지면서 충돌 흡수를 유도하고 아울러 절곡 성형부(15)에 전달되므로, 이때 절곡 성형부(15) 전방 중간에는 비드(16)가 추가로 형성되어 있기 때문에 여기서 충격을 충분히 흡수함은 물론 사이드실 박스(20)의 전체 변형을 방지하게 된다.The present invention configured as described above first absorbs a certain amount of impact when the side seal outer panel 13 of the side seal box 20 collides first, and then the other impact of the center follower panel 11. Since the reinforcing member 14 installed in the front of the bending molded part 15 is crushed to induce collision absorption and transmitted to the bent molding part 15, the bead 16 is further added in the middle of the front of the bending molded part 15. Since it is formed, the shock absorber is sufficiently absorbed here, and the overall deformation of the side seal box 20 is prevented.

또한 센터플로워패널(11)하면에는 제2 보강부재(17)가 추가로 설치되어서 사이드실 아웃터패널(13)의 한쪽단부를 지지하도록 서로 결합되어 있고, 사이드실 아웃터패널(13)의 다른쪽은 센터플로워패널(11)의 절곡 성형부(15)와 사이드실 인너패널(12)과 함께 결합되어 있어서, 충돌흡수와 결합 강성이 증대되어 차량의 측면 충돌시 사이드실 박스(20)가 실내측으로 밀리지 않게 함과 동시에 변형을 방지한다.In addition, a second reinforcing member 17 is additionally installed on the bottom of the center follower panel 11 to be coupled to each other to support one end of the side seal outer panel 13, and the other of the side seal outer panel 13 is Coupling with the bent forming portion 15 of the center follower panel 11 and the side seal inner panel 12, the collision absorption and coupling rigidity is increased, so that the side seal box 20 is pushed to the interior side during side impact of the vehicle And at the same time prevent deformation.

따라서, 이러한 본 고안은 외부로 부터의 충격이 다단계에 걸쳐 흡수 완화됨은 물론 변형이 방지되므로 센터필러와 도어 및 루프의 변형이 최대한 억제되고 인체상해중 골반부에 해당하는 펠비스값이 감소되는 장점이 있다.Therefore, the present invention has the advantage that the impact from the outside is absorbed and relaxed in multiple stages as well as the deformation is prevented, so that deformation of the center pillar, the door and the loop is suppressed as much as possible, and the Pelvis value corresponding to the pelvis in the human injury is reduced. have.

이상에서 살펴본 바와 같이 본 고안은 센터플로워패널이 연장형성되어 중간에 비드가 형성된 절곡 성형부에 보강부재가 설치되어 충돌시 찌그러지면서 충돌흡수를 유도하고 센터플로워패널 하면에는 제2보강부재를 고정 설치하여 사이드실 인너패널 및 아웃터패널과 함께 결합하여 충돌흡수와 결합강성을 증대시켜 측면 충돌시 완충과 보강효과를 향상 시키도록 함으로써 실내의 승객을 최대한 보호할 수 있도록 한 매우 유용한 고안이다.As described above, the present invention has a reinforcement member installed at a bent molding part in which a center follower panel is extended to form a bead in the middle to induce a crash absorption while being distorted during a collision, and fixing a second reinforcing member to the bottom of the center follower panel. This is a very useful design that can be combined with the side seal inner panel and the outer panel to increase the impact absorption and coupling stiffness to improve the shock absorbing and reinforcing effect in the case of side collision.
