본 고안은 자동차 섀시의 측면 중심부에서 섀시를 받쳐주는 센터필러(center pillar)에 관한 것으로, 특히 센터필러를 구성하는 센터필러 내측패널과 센터필러 외측패널 사이에 주보강패널과 보조보강패널을 삽입하여 고정설치하므로써, 센터필러부위의 강성을 증대시켜 차량 측면충돌시 실내로 밀려들어오는 현상을 억제할 수 있게 하여 운전자 및 탑승자의 안전을 도모할 수 있게 한 센터필러 구조에 관한 것이다.The present invention relates to a center pillar supporting the chassis at the center of the side of the automobile chassis, and in particular, a main reinforcement panel and an auxiliary reinforcement panel are inserted between the center pillar inner panel and the center pillar outer panel constituting the center pillar. By the fixed installation, the center pillar structure can be increased by increasing the rigidity of the center pillar portion to suppress the phenomenon of being pushed into the room during the side impact of the vehicle to promote the safety of the driver and the occupant.

일반적으로 자동차의 차체는 주로 차량 정면충돌시에 대비한 충분한 강성을 갖도록 설계·제작되었던 반면에 상대적으로 차량 측면충돌시 가해지는 충격으로부터 탑승자를 보호하는 장치는 아직 미흡한 실정이다.In general, while the vehicle body is designed and manufactured to have sufficient rigidity mainly in front of the frontal collision of the vehicle, the device for protecting the occupant from the impact of the impact on the side of the vehicle is still insufficient.

따라서, 차량 측면충돌시에 의해 발생하는 피해가 늘어나고 그 피해정도가 커지고 있는 추세에 따라 이에 대한 관계법규가 강화되고, 또한 수출용 차량에 대한 대외적인 법규 규제등으로 인하여 그 중요성이 점차 인식되고 있는 것이 최근의 실정인 바, 이러한 관점에서 볼 때 자동차의 차체 측면구조가 특히, 승용차 섀시의 센터필러부위에 대한 구조개선의 필요성이 높아지고 있다.Therefore, as the damage caused by the side of the vehicle increases and the degree of damage increases, the related laws are strengthened, and its importance is gradually recognized due to the external regulations on export vehicles. In view of the recent situation, the vehicle body side structure in particular, in particular, the need for structural improvement of the center pillar portion of the passenger car chassis is increasing.

종래 일반적인 센터필러의 구조는, 첨부도면 제3도에 도시한 바와 같이, 상하부로 서로 마주보는 형태로 일정한 공간부(15)를 형성하면서 센터필러 내측패널(13)과 센터필러 외측패널(14)의 좌우측단부가 밀착되어 용접등으로 고정설치되며, 센터필러 내측패널(13)의 상부로는 후론트 도어패널(11)과 리어 도어패널(12)이 위치되는 구조로 이루어져 있다.As shown in FIG. 3, the center pillar structure of the related art has a center pillar inner panel 13 and a center pillar outer panel 14, while forming a constant space portion 15 in a form facing each other in the upper and lower portions. The left and right end portions of the center pillar are in close contact with each other and fixedly installed by welding. The upper portion of the center pillar inner panel 13 has a structure in which the front door panel 11 and the rear door panel 12 are positioned.

그러나, 이와 같은 기존의 센터필러구조는 차량 측면충돌시 충분한 지지강성을 갖기에는 매우 취약한 구조로 이루어져 있음을 알 수 있는 바, 측면충돌시 센터필러부위가 내부공간으로 심하게 밀리게 되는 등의 손상을 받게 됨에 의해 자체 지지기능을 잃어버리게 되는 많은 문제점을 가지고 있었다.However, it can be seen that the existing center pillar structure is very fragile to have sufficient support stiffness in the event of a side collision, such that the center pillar portion is severely pushed into the internal space during side collision. There were many problems that resulted in the loss of self-support.

따라서, 본 고안은 이와 같은 점을 감안하여 안출한 것으로서, 상기 센터필러 내측패널과 외측패널 사이에 육각형 형태의 공간부를 형성하면서 서로 마주보는 형태로 절곡성형된 주보강패널과 이 주보강패널의 저면으로는 센터필러 내측패널에 소정의 공간부를 형성하면서 절곡성형된 보조보강패널을 용접으로 고정설치하므로서, 차체의 횡방향 강성을 보강한 자동차의 센터필러구조를 제공하는 데 그 목적이 있는 것이다.Accordingly, the present invention has been devised in view of the above, and the main reinforcement panel and the bottom surface of the main reinforcement panel are bent in a form facing each other while forming a hexagonal space portion between the center pillar inner panel and the outer panel. The purpose of the present invention is to provide a center pillar structure of an automobile which reinforces the lateral rigidity of the vehicle body by fixing the auxiliary reinforcement panel bent by welding while forming a predetermined space portion in the center pillar inner panel by welding.

이하, 첨부도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, described in detail with reference to the accompanying drawings.

본 고안에 따른 센터필러의 구조는 제 2도에 나타낸 바와 같이, 센터필러 내측패널과 외측패널이 일정한 완충공간부를 형성하면서 좌우측 끝단부위에서 서로 밀착되어 융착된 구조로 이루어진 자동차의 센터필러구조에 있어서, 센터필러 내측패널(23)과 외측패널(24) 내부에는 재차 절곡성형되면서 중간부위에서는 서로 마주보는 형태를 취하면서 육각형 모양의 완충공간부(25b)를 형성하는 주보강패널(26)이 양 끝단부가 센터필러 내외측패널(23, 24)의 양 끝단부의 패널 접합부 사이에 삽입되어 용접등으로 고정설치되고, 센터필러 내측패널(23) 중간 수평부에서 상자형 공간부(25d)를 형성하도록 상부로 절곡성형된 보조보강패널(27)이 융착 고정된 것을 특징으로 한다.In the center pillar structure of the vehicle according to the present invention, as shown in FIG. 2, the center pillar structure of the vehicle is formed in which the center pillar inner panel and the outer panel are fixed to each other at the left and right end portions while forming a constant buffer space portion. In the center pillar inner panel 23 and the outer panel 24, the main reinforcement panel 26 forming the hexagonal buffer space 25b while forming a hexagonal buffer space portion 25b while being formed to be bent again to face each other in the middle portion. The end is inserted between the panel joints of both ends of the center pillar inner and outer panels 23 and 24 to be fixed by welding, and to form a box-shaped space 25d at the middle horizontal portion of the center pillar inner panel 23. The secondary reinforcement panel (27) bent upwardly is fused and fixed.

이를 좀더 상세히 설명하면, 상기 센터필러 내측패널(23)과 외측패널(24)은 길이방향을 따라 서로 마주보는 형태로 절곡성형되어 양 끝단부위는 용접등으로 고정설치되며, 상기 센터필러 내외측패널(23, 24)의 내부에는 길이방향으로 재차 절곡성형되면서 중간부위에서는 상하부로 소정의 깊이만큼 절곡부를 가지면서 육각형 모양의 완충공간부(25b)를 형성하는 주보강패널(25)이 좌우측 끝단부가 상기 센터필러 내외측패널(23, 24)의 양 끝단부위의 패널 접합부 사이에 삽입되어 용접 등으로 고정설치된다.In more detail, the center pillar inner panel 23 and the outer panel 24 are bent to face each other along the longitudinal direction so that both ends are fixed by welding and the like, and the center pillar inner and outer panels are formed. The left and right ends of the main reinforcement panel 25 forming the hexagonal buffer space 25b having a bent portion with a predetermined depth in the middle portion while being bent again in the longitudinal direction inside the 23 and 24 parts. It is inserted between the panel joints at both ends of the center pillar inner and outer panels 23 and 24 and fixedly installed by welding or the like.

이때, 상기 주보강패널(26)의 중간부위의 상부로는 상단부로 소정의 깊이로 절곡성형되어 상술한 육각형 모양의 공간부(25b)를 형성하면서 좌우측으로 일체 용접되어진다.At this time, the upper portion of the middle portion of the main reinforcement panel 26 is bent to a predetermined depth to the upper end portion is welded integrally to the left and right sides while forming the above-described hexagonal space portion 25b.

또한, 센터필러 내측패널(23) 하단부의 수평부 내측면에는 길이방향을 따라 상기 주보강패널(26)과 마주보는 형태로 상향절곡되어 상자형의 완충공간부(25d)를 형성하면서 센터필러 내측패널(23)의 수평부 내측면 좌우측에 용접등으로 융착 고정설치된다.In addition, the inner side of the center pillar inner panel 23 is bent upwardly in a form facing the main reinforcement panel 26 along the longitudinal direction to form a box-shaped buffer space portion 25d along the longitudinal direction. It is fusion-fixed and installed in the left and right sides of the horizontal part inner surface of the panel 23 by welding etc.

여기서, 상기 센터필러 내외측패널(23, 24) 사이에 주보강패널(26)과 보조보강패널(27)를 융착시켜 용접등으로 고정설치하므로써, 다수의 완충공간부(25a, 25b, 25c, 25d)를 형성하여 센터필러(10)부위의 강성을 증대시키고 차량 측면충돌시의 충격력을 각각의 공간부(25a, 25b, 25c, 25d) 및 주보강패널(26)과 보조보강패널(27)에 의하여 완화시키는 동시에 흡수할 수 있게 된다.Here, the main reinforcing panel 26 and the auxiliary reinforcing panel 27 are fused between the center pillar inner and outer panels 23 and 24 to be fixed by welding or the like, so that a plurality of buffer space portions 25a, 25b, 25c, 25d) is formed to increase the rigidity of the center pillar 10 portion and the impact force in the event of a side collision of the vehicle 25a, 25b, 25c, 25d, the main reinforcement panel 26 and the auxiliary reinforcement panel 27 This can alleviate and absorb the same.

즉, 상기 센터필러 내측패널(23)과 외측패널(24) 사이에 주보강패널(26)과 보조보강패널(27)을 설치하여 공간부(25a, 25b, 25c, 25d)가 형성되므로써, 차체의 충격력은 상기 제 1, 2 공간부(25a, 25b)와 주보강패널(26)에 의해 1차 저감되고, 이렇게 감쇄된 충격력은 제 3, 4 공간부(25c, 25d) 및 보조보강패널(27)에 의하여 2차 저감됨과 동시에 흡수하게 되므로써, 센터필러(10)가 내부공간으로 밀려들어오는 정도가 현저히 줄어들게된다.That is, since the main reinforcing panel 26 and the auxiliary reinforcing panel 27 are provided between the center pillar inner panel 23 and the outer panel 24, the spaces 25a, 25b, 25c, and 25d are formed, thereby providing a vehicle body. The impact force of the first and second spaces (25a, 25b) and the primary reinforcement panel 26 is reduced by the first, the impact force is reduced by the third, fourth spaces (25c, 25d) and auxiliary reinforcement panel ( 27) by the secondary reduction and at the same time absorbed, the degree to which the center pillar 10 is pushed into the interior space is significantly reduced.

이상에서와 같이 본 고안은 차체 측면 센터필러부위의 패널구조를 보강하므로써, 차체의 강성을 증대시켜 차량 측면충돌시 센터필러부의 밀림정도를 최소화하여 탑승자의 안전을 최대한 보호할 수 있는 장점이 있는 것이다.As described above, the present invention reinforces the panel structure of the side center pillar portion of the vehicle body, thereby increasing the rigidity of the vehicle body and minimizing the centering degree of the center pillar portion during the vehicle side collision, thereby protecting the occupant's safety as much as possible. .
