본 발명은 자동차의 루프패널(Roof Pannel)구조에 관한 것으로 특히 승용차의 루프패널을 구성하는 수개의 보강재가 단일체로 구성된 자동차 루프패널 구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof panel structure of a vehicle, and more particularly, to a vehicle roof panel structure in which several reinforcements constituting a roof panel of a passenger car are composed of a single body.

제1도 및 제2도에서와 같이, 종래의 루프패널은 루프패널(1) 안쪽으로 프론트레일(10)과 센터레일(12) 및 리어레일(14)이 보강재로 결합되고, 양측으로 사이드레일(15)등 수개의 보강재(10~15)가 접합된 구조를 이루고 있었다.As shown in FIG. 1 and FIG. 2, the conventional roof panel has a front rail 10, a center rail 12 and a rear rail 14 coupled by reinforcement to the inside of the roof panel 1, and side rails on both sides. Several reinforcing materials 10-15, such as (15), were comprised.

그러나, 상기한 종래의 루프패널구조는 상기 수개의 레일 보강재(10~15)를 별도로 형성시켜 조립, 접합시킨 것이므로 별도의 금형제작으로 인한 금형비가 상승되고, 작업공정 수가 많게 되며, 상기 루프패널과 다른 패널과의 접합시에 정밀하게 맞추어 조립해야 하므로 조립성이 저하되는 등 여러 폐단이 많았었다.However, since the conventional roof panel structure is formed by assembling and assembling the rail reinforcements 10 to 15 separately, the mold cost is increased due to the manufacture of a separate mold, and the number of work steps increases, and the roof panel When joining with other panels, it was necessary to precisely assemble and assemble, and there were many closures such as poor assembly.

본 발명은 이러한 종래의 루프패널이 그 구조상 지니게 되는 문제점을 해소시킨 루프패널 구조를 제공하는데 그 안출 목적이 있는 것이다.The present invention aims to provide a roof panel structure which solves the problems of such a conventional roof panel structure.

이러한 목적을 달성하기 위해서, 루프패널의 하부에 설치되는 보강재를 종래의 보강재가 결합된 것과 같은 위치 및 방향에 각각 보강부를 형성시킨 것으로, 이렇게 형성되는 보강부는 차체의 구조역학적 특성을 고려하여 프레스금형에서 쉽게 가감시킬 수 있으므로써, 일체 성형에 따른 금형비 절감이나 조립공정의 단축 및 작업성 향상의 효과를 얻을 수 있게 한 것이다.In order to achieve this purpose, the reinforcing material installed in the lower part of the roof panel is formed in the same position and direction as the conventional reinforcing material combined, the reinforcing part is formed in consideration of the structural dynamics of the vehicle body press mold It can be easily added to or reduced from, thus reducing the mold cost, shortening the assembly process and improving workability due to the integral molding.

이하, 첨부도면을 참고하여 본발명을 더욱 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

본 발명은 자동차 루프패널(1)의 보강제(10~16)에 횡방향 보강재역할의 프론트레일(10)과 센터레일(12)과 리어레일(14)및 사이드 레일(15)을 단일체로 프레스가공하고, 종방향으로도 종방향레일(16)을 형성시켜 이루어지는 자동차 루프패널 구조이다.According to the present invention, the front rail 10, the center rail 12, the rear rail 14, and the side rail 15 of the transverse reinforcement material are pressed into the reinforcement 10 to 16 of the vehicle roof panel 1 in one piece. In addition, the longitudinal rail 16 is also formed in the vehicle roof panel structure.

제3도는 본 발명에 따른 루프패널구조로써, 제4도에 A부 상세를, 제5도에 B부 상세를 도시한 바, 상기 보강제(10~16)의 프론트레일(10)은 루프패널(1)의 평명에 대해 아래로 눌려져 있으며, 횡방향 강성을 증대시키도록 한 횡방향 경사면(18)은 그 측단면이 사다리꼴로 경사지게 형성되는 한편, 양단에도 사이드레일(15)과 경사면(20)으로 마감되어 단일의 프론트레일(10)을 이루게 함으로써 프레스 가공시의 용이성과 강성 증대의 효과를 모두 만족시키도록 한다.3 is a roof panel structure according to the present invention. As shown in FIG. 4 and part B in FIG. 5, the front rail 10 of the reinforcement 10 to 16 is a roof panel ( The lateral inclined surface 18, which is pressed downward with respect to the flatness of 1) and which increases the lateral rigidity, is formed with a trapezoidal side cross section thereof, while the side rails 15 and the inclined surface 20 are also provided at both ends. By finishing to form a single front rail (10) to satisfy all the effects of the ease and rigidity increase during the press working.

또한, 센터레일(12)은 상기 프론트레일(10)과 유사한 곡면을 갖지만 그 폭을 좁게 하여 여러개의 경사면이 형성되도록 하고, 리어레일(14)은 상기 프론트레일(10)과 거의 대칭 형태로 제작되어 횡방향 강성 보강 기능을 갖게 된다.In addition, the center rail 12 has a curved surface similar to the front rail 10, but the width thereof is narrowed to form a plurality of inclined surface, the rear rail 14 is manufactured in a substantially symmetrical form with the front rail 10 It has a lateral rigid reinforcement function.

이와함께 종래에는 없던 종방향레일(16)을 형성시키는데, 횡방향레일과 같은 형상도 좋으며 마치 물결무늬와 같은 여러 골을 만들어서 강성을 증대시키도록 해도 좋다.Along with this, a longitudinal rail 16 which is not conventionally formed is formed. The longitudinal rail 16 may have a shape such as a transverse rail and may increase the rigidity by making various valleys, such as a wavy pattern.

물론 이러한 각 레일의 형상은 서로 교차되는 부분이 많아서 비록 하나의 금형을 이용하여 단한번의 프레스로 완성품을 얻기 어려우나 두번 정도의 연속 반복된 프레스로 완성품을 얻을 수 있게 되며, 이는 상기 보강재(10~15)가 지극한 경밀도를 요구하는 것이 아니고, 부분적인 치수만 충족시켜 주면되는 부품이므로 이러한 작업이 가능하게 되는 것이다.Of course, the shape of each of these rails has a lot of intersections with each other, although it is difficult to obtain a finished product with a single press using a single mold, but the finished product can be obtained with two consecutive repeated presses. This is possible because it is not a part that 15) demands extremely light density, but only a partial dimension.

상기한 구성에 따라 바디패널을 보강재인 각 레일과 일체로 혈성되어져서, 종래에는 차체기둥에 스크류나 보울트를 사용하여 각각의 레일을 먼저 접합시킨 후 루프패널을 덮어 씌우는 작업이 병행되어야 했지만, 본 발명에 따른 루프패널은 보강재를 일체로 형성하여 결합위치에 루프패널을 결착시키기만 하면 별도의 보강재 조립공정이 필요 없게 되어 작업성을 향상시킬 수 있게 된다.According to the above configuration, the body panel is integrally formed with each rail as a reinforcing material, and in the past, each rail was first joined by using a screw or bolt to the body column, and then the work of covering the roof panel had to be performed in parallel. The roof panel according to the present invention can improve workability by forming a reinforcing material integrally so as to bind the roof panel at a joining position without the need for a separate reinforcing material assembling process.
