It relates to a center pillar structure to minimize the amount of impact transmitted to the.
일반적으로 자동차의 충돌사고시 승객의 안전을 확보하기 위한 테스트로는 전방충돌(FRONT IMPACT)과 측면충돌(SIDE IMPACT)이 있으며, 이는 자동자의 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. Has been used as a large item such as import regulation by legalizing the safety level.
그러나 현재 생산되고 있는 자동차는 대부분 전방충돌에 대한 안전치는 어느정도 확보하고 있으나, 측면충돌에 대한 안전치는 미흡한 실정이다.However, most of the cars currently produced have a certain level of safety against forward collisions, but the safety against side collisions is insufficient.
즉 그 원인으로는 제1도에 도시된 바와같이 센터필러(10)의 구조가 취약하기 때문이며, 실제로 타차량과의 측면충돌시 센터필러(10)는 물론 도어, 루프 상단까지 변형이 오고, 이로인해 승객인체의 상해치중 골반부에 해당하는 펠비스(PELVIS)값이 커지게 되는 문제가 있었다.That is because the structure of the center pillar 10 is weak as shown in Figure 1, in fact, when the side collision with other vehicles, the center pillar 10, as well as the deformation of the door, the top of the roof comes to this Due to this problem, the PELVIS value corresponding to the pelvis of the injury of the passenger body is increased.
제2도는 이러한 종래의 문제점을 보이는 센터필러구조의 개략적 조립단면도로서, 센터인너패널((CENTER INNER PANEL ; 2) 센터아웃터패널(CENTER OUTER PANEL ; 3)이 마주결합되어 중공부가 형성된 센터필러박스(CENTER PILLAR BOX ; 10)를 이루게 되고, 이 센터필러박스(10)내에서 샌터인너패널(2)에 대응하도록 절곡형성된 보강부재(4)가 설치된 구성이므로 차량 측면 충돌시 지지기반이 매우 취약한 센터아웃터패널(3)이 충격에 의해 밀리면서 보강부재(4), 센터인너패널(2)이 실내로 밀리게 되어 도어 및 루프상단까지 변형이 초래되어 인체상해 중 골반부에 해당하는 펠비스값이 좋지 않은 문제점이 있었다.2 is a schematic assembly cross-sectional view of the center pillar structure exhibiting such a conventional problem, the center inner panel (CENTER INNER PANEL; 2) the center outer panel (CENTER OUTER PANEL; CENTER PILLAR BOX (10) and the center pillar box (10) in the center pillar box (10) is installed in the reinforcement member bent to correspond to the sander inner panel (2) is installed so that the center of the support base is very weak when the vehicle side collision As the panel 3 is pushed by the impact, the reinforcing member 4 and the center inner panel 2 are pushed into the room, causing deformation to the upper part of the door and the roof. There was a problem.
본 고안의 목적은 상기에서와 같은 종래의 문제점을 해소하기 위해 안출된 것으로서, 자동차의 측면충돌시 센터필러박스의 전방부에서 일차로 충분한 충격흡수를 수행할 수 있도록 함과 동시에 후방부에서 이차로 충격을 흡수하여 실내의 승객에 전달되는 충격량을 최대한 줄일 수 있도록 한 자동차의 센터필러 구조를 제공하는데 있다.The object of the present invention is to solve the conventional problems as described above, to provide sufficient shock absorption in the front of the center pillar box in the case of a side collision of the vehicle at the same time as a secondary from the rear It is to provide a center pillar structure of a vehicle to absorb the impact to reduce the amount of impact transmitted to passengers in the room as much as possible.
상기의 목적을 달성하기 위한 본 고안은 상호 반대쪽으로 센터인너패널과 센터아웃터패널이 마주 결합되어 그 사이에 센터아웃터패널에 대응 절곡된 보강부재가 설치되어 있는 센터필러박스에 있어서, 센터인너패널과 보강부재 사이에는 전방으로 곡면 절곡된 제2보강부재가 더 설치되고 센터인너패널의 중간이 분리되어 양단부가 전방으로 절곡되어 접착 및 용접 결합되어 보강돌출부를 형성함으로써 강성을 증대시키도록 된 것을 특징으로 한다.The present invention for achieving the above object is in the center pillar box and the center inner panel is provided with a reinforcing member bent to correspond to the center outer panel and the center inner panel and the center outer panel are opposed to each other, the center inner panel and Between the reinforcing member is further provided a second reinforcing member bent forward curved and the middle of the center inner panel is separated so that both ends are bent forward to be bonded and welded to increase the rigidity by forming a reinforcement protrusion do.
이하 첨부된 도면을 참조하여 본 고안의 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration of the present invention with reference to the accompanying drawings in detail.
제3도는 본 고안의 센터필러(20)의 구조를 나타낸 조립단면도로서, 이를 참조하면 상호 반대쪽으로 절곡된 센터인너패널(12)과 센터아웃터패널(13)이 마주 보도록 결합되고 그 사이에는 센터아웃터패널(13)에 대응되게 절곡된 보강부재(14)가 설치되어 센터필러박스(20)를 구성하게 되는 바, 센터인너패널(12)과 보강부재(14)사이에는 본 고안의 특징에 의해 전방으로 곡면 형태를 이루며 외향 탄발되도록 절곡 형성된 제2보강부재(15)가 위치되고, 제2보강부재(15)의 양단은 보강부재(14)와 센터인너패널(12)의 양단부 사이에 끼워져 함께 스폿용접에 의해 일체로 결합된다. 또한 센터인너패널(12)의 중간 부위는 분리되어서 전방측으로 소정길이 절곡 연장되어 겹쳐져서 겹쳐진 부위는 스폿용접에 의해 일체로 결합되어 보강돌출부(16)를 형성하게 된다.3 is an assembly cross-sectional view showing the structure of the center pillar 20 of the present invention, referring to the center inner panel 12 and the center outer panel 13 which are bent in opposite directions to each other, and the center outer panel therebetween. The reinforcing member 14 bent to correspond to the panel 13 is installed to form the center pillar box 20, between the center inner panel 12 and the reinforcing member 14 in front of the feature of the present invention The second reinforcing member 15 is formed to be curved to form a curved shape outwardly, and both ends of the second reinforcing member 15 are sandwiched between both ends of the reinforcing member 14 and the center inner panel 12 to be spotted together. It is integrally joined by welding. In addition, the middle portion of the center inner panel 12 is separated by a predetermined length bent extending to the front side overlapping overlapping portions are integrally coupled by spot welding to form a reinforcement protrusion (16).
이와같이 구성된 본 고안은 자동차의 측면으로 부터 충격이 가해지게 되면 먼저 센터아웃터패널(13)이 찌그러지면서 충격을 일차로 흡수하게 되고, 이어서 감소된 충격력이 보강부재(14)에 흡수되어 경감된 상태로 센터인너패널(12)측으로 진행하게 된다. 이때 나머지 충격력은 본 고안의 특징부인 제2보강부재(15)바로뒤에 형성된 센터인너패널(12)의 보강돌출부(16)에는 충격력이 거의 전달되지 않게 되므로서 센터인너패널(12)이 파손되거나 변형되지 않게 된다.When the impact is applied from the side of the vehicle, the present invention configured as described above first absorbs the shock as the center outer panel 13 is crushed, and then the reduced impact force is absorbed and reduced by the reinforcing member 14. The process proceeds to the center inner panel 12 side. At this time, the remaining impact force is hardly transmitted to the reinforcement protrusion 16 of the center inner panel 12 formed immediately behind the second reinforcing member 15, which is a feature of the present invention, so that the center inner panel 12 is broken or deformed. Will not be.
따라서 본 고안의 센터필러구조는 외부의 충격력에 의해 센터아웃터패널(13)이 밀리면서 보강부재(14)로 전달되어 뒤로 밀리더라도 일차적으로 경감된 충격력이 제2보강부재(5)탄발력에 의해 대부분이 흡수되어 센터인너패널(12)의 보강돌출부(16)에는 거의 전달되지 않게 됨으로써 센터인너패널(12)은 물론 도어 및 루프의 변형을 방지할 수 있게 되어 승객의 안전을 도모하게 된다.Therefore, the center pillar structure of the present invention is transmitted to the reinforcing member 14 while the center outer panel 13 is pushed by the external impact force, even if the back force is primarily reduced by the second reinforcement member 5 elasticity. Since most of them are absorbed and hardly transmitted to the reinforcement protrusions 16 of the center inner panel 12, the center inner panel 12 can be prevented from being deformed as well as the doors and the loops, thereby promoting passenger safety.
이상에서와 같이 본 고안은 센터필러박스 내부에 통상의 보강부재의 후면에 제2보강부재가 설치되고 그 후방으로 센터인너패널에 형성된 보강돌출부가 구비되므로써 자동차의 측면 충돌시 그 충격을 다단계로 감소시켜 실내의 승객을 보호할 수 있도록 된 매우 유용한 고안인 것이다.As described above, the present invention has a second reinforcing member installed at the rear of the normal reinforcing member inside the center pillar box, and a reinforcing protrusion formed at the center inner panel is provided at the rear thereof, thereby reducing the impact in multiple stages of the vehicle. It is a very useful design to protect the passengers in the room.
