Abstract

PURPOSE: A structure for a roof rail of a vehicle is provided to cut down the cost, to prevent the roof rail from rolling, and to reinforce supporting strength by forming upper and lower rails in a box shape. CONSTITUTION: Plate-shaped upper and lower rails(1,2) are welded and combined. A roof panel(3) is combined on the welded upper and lower rails by an adhesive sealer. A cross supporting unit(4) and a reinforcing groove(5) are formed at the upper rail. The plate-shaped lower rail props up the upper rail. The cross supporting unit of the upper rail prevents a roof rail of a vehicle from rolling. The reinforcing groove increases strength of the roof rail. The roll-back of a roof side is reduced even by a broadside collision of the vehicle by reinforcing combination structure of the roof side.

자동차의 루프레일 구조{roof rail structure of vehicle}Roof rail structure of vehicle

본 발명은 자동차의 루프판넬을 지지결합하는 루프레일의 구조를 개선하여, 꿀렁거림을 방지하고 측면충돌시 루프사이드의 지지강성 증대로 안정성이 확보되게 한 자동차의 루프레일 구조에 관한 것이다.The present invention relates to a roof rail structure of a vehicle which improves the structure of a roof rail supporting and coupling a roof panel of a vehicle, thereby preventing slack and ensuring stability by increasing support stiffness of the roof side during side collision.

종래의 루프레일은 도 3에 도시된 바와 같이 1개의 프론트레일(10)과, 3개의 센터레일(20) 및, 1개의 리어레일(30)을 배치하여 그 상부에 루프판넬(40)이 지지되게 구성하였다.In the conventional roof rail, as shown in FIG. 3, one front rail 10, three center rails 20, and one rear rail 30 are disposed to support the roof panel 40 thereon. It was configured.

그러나, 상기와 같은 기존의 루프레일은, 부품수의 증가와 조립부분의 증대로 금형비, 조립비에 의한 원가상승의 문제가 있으며, 공간이 밀폐되지 않은 개단면 구조여서 시간이 경과되면서 자체변형에 의해 실러부가 떨어지고 루프판넬의 꿀렁거림 현상이 발생하는 문제점이 있었다.However, the existing roof rail as described above has a problem of cost increase due to mold cost and assembly cost due to an increase in the number of parts and an increase in assembly parts. There was a problem in that the sealer was dropped and the wobble of the roof panel occurred.

특히, 도 4에 도시된 바와 같이 사이드부 즉, 루프판넬(40)과 센터레일(20)의 끝단부와, 루프사이드인너판넬(50)과 아웃터판넬(60) 및 보강판넬(70)이 결합되는 이음부(80)의 지지강성이 취약하여 측면충돌시 승객의 안전성을 보호하지 못하는 문제가 있었다.In particular, as shown in FIG. 4, the end portions of the side parts, that is, the roof panel 40 and the center rail 20, the roof side inner panel 50, the outer panel 60, and the reinforcement panel 70 are coupled to each other. There was a problem in that the support rigidity of the joint portion 80 is weak, which does not protect the safety of the passengers during side collisions.

이에 본 발명은 상기와 같은 문제점을 해소하기 위해 안출된 것으로, 루프레일을 어퍼레일과 로어레일을 결합한 박스형으로 형성하여 일체형 적용에 따른 원가절감과 출렁거림의 방지 및 지지강성의 강화를 통해 안정성이 향상되게 한 자동차의 루프레일 구조를 제공함에 그 목적이 있다.Therefore, the present invention was devised to solve the above problems, and the loop rail is formed in a box shape in which the upper rail and the lower rail are combined, thereby reducing the cost and preventing the lumpiness and strengthening the support rigidity. The object is to provide a roof rail structure of an automobile that has been improved.

상기와 같은 목적을 달성하기 위한 본 발명의 루프레일구조는, 판체상의 어퍼레일과 로어레일을 구분 형성하여 용접결합하고, 그 상부에 접착실러를 이용하여 루프판넬을 결합하되, 상기 어퍼레일에는 십자형 지지대와 보강용 그루브를 형성하고, 상기 로어레일은 판체로 형성하면서 상기 어퍼레일을 받쳐주도록 하여 박스형으로 구성되게 함을 특징으로 한다.The roof rail structure of the present invention for achieving the above object, the upper rail and the lower rail on the plate to form a separate weld, and the roof panel is coupled to the upper rail using an adhesive seal, the upper rail cross-shaped Forming a support and a reinforcing groove, the lower rail is characterized in that the box is formed by supporting the upper rail while forming a plate body.

이하, 본 발명의 실시예를 첨부도면에 의거 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 루프레일의 분리사시도이다.1 is an exploded perspective view of a roof rail according to the present invention.

본 발명은, 판체상의 어퍼레일(1)과 로어레일(2)을 구분형성하여 용접결합하고, 그 상부에 루프판넬(3)을 접착실러에 의해 결합한다.In the present invention, the upper rail (1) and the lower rail (2) on the plate body are formed by welding, and the roof panel (3) is joined to the upper portion by an adhesive sealer.

여기서, 상기 어퍼레일(1)에 십(+)자형 지지대(4)와 보강용 그루브(5)를 형성하고, 상기 로어레일(2)은 판체로 형성하여 어퍼레일(1)을 받쳐줌으로서 박스형으로 구성한다.Here, a cross (+) shaped support 4 and a reinforcing groove 5 are formed on the upper rail 1, and the lower rail 2 is formed in a plate shape to support the upper rail 1 by a box shape. Consists of.

이와 같이 구성된 본 발명의 작용을 설명한다.The operation of the present invention configured as described above will be described.

본 발명의 루프구조는 종래와 같은 5개의 루프레일이 필요없이 한판으로 된 어퍼레일(1)과 로어레일(2)의 결합만으로 이루어짐으로써, 부품수가 절감되고 조립공정이 감축되게 된다.The roof structure of the present invention is composed of only the upper rail 1 and the lower rail 2 made of a single plate without the need for five loop rails as in the prior art, thereby reducing the number of parts and reducing the assembly process.

또한, 상기 어퍼레일(1)의 십(+)자형 루프지지로 꿀렁거림이 방지됨으로써 상품성이 향상되고, 판상의 어퍼레일(1)과 로어레일(2)의 용접결합으로 박스형으로 이루어지고 그 보강용 그루브(5)에 의해 강성이 증대됨과 함께 도 2의 도시된 바와 같이 루프 사이드부의 결합구조 강화로 자동차의 측면충돌시에도 루프사이드의 밀림이 감소되어 승객의 안정성이 확보될 수 있게 된다.In addition, the productability is improved by preventing snarl by the cross-shaped roof support of the upper rail 1, and the box-shaped upper rail 1 and the lower rail 2 are welded to form a box shape and reinforcement thereof. As the rigidity is increased by the dragon groove 5 and the coupling structure of the roof side portion is strengthened as shown in FIG. 2, the sliding of the roof side may be reduced even when the vehicle is collided with the roof side, thereby securing passenger safety.

이상 설명한 바와 같이 본 발명에 의하면, 루프레일구조가 어퍼레일과 로어레일에 의한 박스형으로 구성됨으로써 부품과 조립공정의 절감으로 원가가 절감되고 출렁거림이 방지되며 측면충돌시 루프사이드의 밀림현상이 감소되어 승객의 안정성을 확보할 수 있는 효과가 있게 된다.As described above, according to the present invention, the roof rail structure is formed of a box type by upper rails and lower rails, thereby reducing the cost of components and assembly processes, preventing slumping, and reducing the sliding of the roof side during side collision. Therefore, there is an effect that can ensure the stability of the passengers.
