본 고안은 자동차용 중앙필라체결단의 보강구조에 관한 것으로, 특히 중앙 필라의 차체 접합을 위한 체결단이 확장되어 차체 측면의 강성이 향상되도록 됨은 물론, 차체 정면충돌등 전방에서 가해지는 충격을 완화시킬 수 있도록 되어 충돌사고시 안정성을 향상시킬 수 있도록 됨과 더불어, 외부판넬부와 내부판넬부간의 지지·체결력을 형성하여 주행 및 외부공기유동에 따른 소음을 저감시킬 수 있도록 된 자동차용 중앙필라체결단의 보강구조에 관한 것이다.The present invention relates to the reinforcement structure of the central pillar fasteners for automobiles. In particular, the fastening ends for the body pillars of the central pillars are expanded to improve the rigidity of the side surfaces of the vehicle, as well as to mitigate shocks applied from the front of the vehicle, such as frontal collisions. It is possible to improve the stability in the event of a crash, and to form a support and tightening force between the outer panel and the inner panel, thereby reducing the noise caused by driving and external air flow. It relates to a reinforcement structure.

일반적으로, 차체 측면에 구비된 도어판넬 외곽부에는 도어판넬의 지지와 차체 형상 형성 및 차체 측부강성 유지를 위한 필라가 체결되는 바, 이 필라는 차체 전방의 엔진실 후단부와 접하면서 전방윈드쉴드글래스 등을 지지할 수 있도록 차체 전방으로 소정각도 기울어져 뻗어 전방도어의 선단에 취부된 전방필라와, 상기 전방도어와 후방도어 사이에 취부되어 상기 도어를 지지할 수 있도록 됨은 물론, 도어로 인해 개구된 차체 측면을 중방향에 걸쳐 지지하도록 된 중앙필라 및, 후방도어의 후방끝단에 체결되면서 상기 도어와 후방글래스 및 후방차체를 지지하도록 된 후방필라로 이루어진다.In general, a pillar for supporting the door panel and forming a body shape and maintaining the body side rigidity is fastened to the outer side of the door panel provided at the side of the body. The front pillar is mounted at an angle to the front of the vehicle body so as to support the glass, and the front pillar is mounted between the front door and the front door and the rear door to support the door. The center pillar is configured to support the side of the vehicle body in the middle direction, and the rear pillar is configured to support the door, the rear glass and the rear vehicle body while being fastened to the rear end of the rear door.

여기서, 상기 중앙필라는 종래에 도3에 도시된 바와 같이, 차체 상단을 덮어 막을 수 있도록 대략 직사각형 판 형상을 이룬 외측루프판넬(2)이 구비되고, 이 외측루프판넬(2)의 좌·우측선단에서 외측으로 소정폭 돌출·절곡되면서 상기 외측루프판넬(2)의 횡방향 폭과 동일폭을 이루도록 된 사이드판넬(1)이 접합되는 한편, 상기 외측루프판넬(2)과 하방향으로 소정간격 이격된 위치에 외측루프판넬(2)과 동일 형상을 이루도록 된 내측루프판넬(3)이 구비되고, 이 내측루프판넬(3)의 좌·우측선단에서 상기 사이드판넬(1)의 외측 선단에 이르도록 뻗어 내측루프판넬(3)과 사이드판넬(1)의 전·후폭과 동일폭을 이루도록 루프레일(4)이 차체 횡방향으로 뻗어 형성되는 바, 차체 측면 중앙부에 직사각형 판 형상을 이루고 종방향으로 뻗어 형성되어 차체 상부측면의 사이드판넬(1)과 차체 하부측면의 사이드프레임에 걸쳐 취부되도록 된 중앙필라의 상부 좌·우측에서 중앙필라의 형성방향과 수직을 이루고 뻗어 형성된 필라체결단(6)이 상기 사이드판넬(1)의 내측에 위치되어 루프판넬(2)과 사이드판넬(1)의 접합부 및 사이드판넬(1)과 루프레일(4)의 접합부에서 용접하도록 된다.Here, as shown in FIG. 3, the central pillar is provided with an outer roof panel 2 having a substantially rectangular plate shape so as to cover the upper end of the vehicle body, and to the left and right sides of the outer roof panel 2. The side panel 1 is formed to protrude and bend outward from the front end to a predetermined width so as to have the same width as the transverse width of the outer loop panel 2, while being spaced downward from the outer roof panel 2 by a predetermined distance. The inner loop panel 3 is provided in the spaced apart position so as to have the same shape as the outer roof panel 2, and from the left and right ends of the inner roof panel 3 to the outer end of the side panel 1; The roof rail 4 is formed to extend in the transverse direction of the vehicle body so as to have the same width as the front and rear widths of the inner roof panel 3 and the side panel 1. Formed to extend Pillar fastening 6 formed perpendicularly to the direction of formation of the central pillar and extending from the upper left and right sides of the central pillar to be mounted over the side panel 1 and the side frame of the lower side of the vehicle body is formed of the side panel 1. It is located inside and welded at the junction of the roof panel 2 and the side panel 1 and at the junction of the side panel 1 and the roof rail 4.

따라서, 필라체결단(6)의 접합·고정에 따라 중앙필라가 차체에 접합·고정되어 차체 측면을 종방향으로 지지하도록 되고, 이 중앙필라의 상부에 가해지는 외부충격이 사이드판넬(1)과 필라체결단(6)이 접합되면서 형성된 폐단면부에 의해 완충되도록 되며, 외측루프판넬(2)과 중앙필라를 상호 지지하도록 된다.Accordingly, the center pillar is joined to and fixed to the vehicle body in accordance with the joining and fixing of the pillar fastening end 6 so as to support the side surface of the vehicle body in the longitudinal direction, and the external shock applied to the upper portion of the center pillar is connected to the side panel 1. The pillar fastening end 6 is buffered by the closed end surface portion formed while joining, and the outer roof panel 2 and the central pillar are mutually supported.

그러나 상기와 같이, 필라체결단(6) 및 사이드판넬(1)이 차체와 수평방향으로는 외측루프판넬(2)에 지지되고, 차체와 수직방향으로는 루프레일(4)에 접합·지지되도록 되어 차체 측면에 가해지는 외부충격이 외측루프판넬(2)에 직접 전해져 외측루프판넬(2) 등이 함몰·변형되며, 외측루프판넬(2)과 사이드판넬(1) 및 필라체결단(6)으로 이루어진 외표부와, 내측루프판넬(3)과 루프레일(4)로 이루어진 내측부가 1지점 접합만으로 체결되어 차체 전·후방에서 외부충격이 가해질시 상기 외표부와 내측부가 상호 이탈·변형되는 문제가 발생됨과 더불어, 상기 사이드판넬(1)등 외표부와 루프레일(4)등 내측부가 그 외주부만이 접합된 상태에서 중심부가 상호 이격되어져 있도록 되어 주행진동이나 외부공기유동에 따른 소음이 발생됨은 물론, 상기 소음이 증폭되는 문제가 발생되었다.As described above, however, the pillar fastening end 6 and the side panel 1 are supported by the outer roof panel 2 in the horizontal direction with the vehicle body and joined and supported by the roof rail 4 in the vertical direction with the vehicle body. The external shock applied to the side of the vehicle body is transmitted directly to the outer roof panel 2 so that the outer roof panel 2 is recessed and deformed, and the outer roof panel 2 and the side panel 1 and the pillar fastening 6 The outer part and the inner roof panel 3 and the inner part of the roof rail 4 are fastened by only one point of contact, and the outer part and the inner part are separated from each other and deformed when an external shock is applied to the front and rear of the vehicle body. In addition, the centers are spaced apart from each other in a state where only the outer circumferential part such as the outer part of the side panel 1 and the inner part of the roof rail 4 are joined to each other, so that noise caused by driving vibration or external air flow is generated. Of course, the noise is amplified A problem has occurred.

이에 본 고안은 상기와 같은 제반 문제점을 해소하기 위해 안출된 것으로, 필라체결단이 확장·절곡되어 내측루프판넬과 접합·고정되도록 됨에 따라, 차체측면 상부내에 2개의 폐단면이 형성되어 외부충격에 대한 강성이 향상되도록 되고, 사이드판넬등 외표부와 내측루프판넬 등 내측부가 필라체결단에 의해 상호 체결되도록 되어 차체 강성의 향상 및 소음의 발생·증폭을 저감할 수 있도록 된 자동차용 중앙필라 체결단의 보강구조를 제공함에 그 목적이 있다.Therefore, the present invention was devised to solve the above problems. As the pillar-shaped joint is expanded and bent to be joined and fixed with the inner roof panel, two closed sections are formed in the upper side of the vehicle body, and thus the external impact is prevented. Central pillar fastening end for automobiles to improve the rigidity of the body and to reduce the generation and amplification of noise by making the external parts such as the side panel and the inner parts such as the inner roof panel be fastened together by the pillar fastening. Its purpose is to provide a reinforcing structure of.
