Description

자동차의 루프 보강구조 {Roof Reinforcing Structure of Car}Roof Reinforcing Structure of Car}

본 발명은 자동차의 루프 보강구조에 관한 것으로서, 더욱 상세하게는 프런트레일과 리어레일을 벤딩 형태로 루프패널과 일체화하여 루프 강성 및 정도를 향상시킬 수 있는 루프 보강구조에 관한 것이다.The present invention relates to a roof reinforcement structure of a vehicle, and more particularly, to a roof reinforcement structure which can improve the loop rigidity and accuracy by integrating a front rail and a rear rail with a roof panel in a bending form.

자동차는 기관과 프레임을 비롯하여 자동차의 주행에 필요한 모든 구성 장치를 포함하는 섀시(chassis)와, 이 섀시 위에 설치되어 자동차의 외형을 이루는 부분이며, 기관이 설치되는 기관실, 사람이 탑승하는 차실 및 화물을 수납하는 트렁크실 또는 화물실 등을 포함하는 차체(body)로 크게 구성된다.A car is a chassis that contains the engine and the frame, as well as all the components necessary for driving the car, and is the part of the car that is installed on the chassis, the engine room where the engine is installed, the passenger compartment and cargo It is largely composed of a body (body) including a trunk compartment or a cargo compartment for storing the.

이 차체는 사람이 탑승하는 차실의 경우 바닥을 이루는 플로어(floor), 천정을 이루는 루프 조립체(roof assembly), 엔진룸과 차실을 구획하는 카울 패널(cowl panel), 차실을 개폐하는 도어 및 루프와 플로어를 연결하는 다수의 필라(pillar)로 이루어진다.In the case of a passenger cabin, the floor consists of a floor, a roof assembly, a cowl panel that divides the engine compartment and the cabin, and doors and roofs that open and close the cabin. It consists of a number of pillars connecting the floors.

자동차의 루프 부위는 차체 사이드 부위를 연결하고, 자동차 전체 골격을 유지하는 중요한 부위로서, 루프패널만으로 차체 사이드 부분을 지지하고 외적 충격에 견디기 어려워 루프패널의 하부에는 루프패널을 지지하기 위한 골격이 되는 루 프레일이 설치된다.The roof part of the car is an important part that connects the body side part, and maintains the entire skeleton, and it is difficult to support the body side part only with the roof panel and to withstand external shocks, so it is a skeleton for supporting the roof panel at the lower part of the roof panel. Lou Foil is installed.

상기 루프레일은 차축 방향으로 길게 배치되면서 차체 길이방향을 따라 소정간격으로 이격되게 설치되고, 센터레일 2개와 프런트레일 및 리어레일 1개로 이루어져, 루프패널에 스폿 용접 및 마스틱 실러에 의해 조립된다.The roof rails are disposed long in the axle direction and spaced apart at predetermined intervals along the vehicle body length direction. The roof rails include two center rails, one front rail and one rear rail, and are assembled to the roof panel by spot welding and a mastic sealer.

이를 도 1과 도 2를 참고로 하여 상세히 설명하면 다음과 같다.This will be described in detail with reference to FIGS. 1 and 2 as follows.

도 1a와 도 1b는 종래 루프의 조립 방법을 설명하기 위한 도면이고, 도 2a와 도 2b는 도 1b의 A-A선과 B-B선의 단면도이다.1A and 1B are views for explaining a method of assembling a conventional loop, and FIGS. 2A and 2B are cross-sectional views taken along lines A-A and B-B of FIG. 1B.

2개의 센터레일(2,3)과 루프패널(1) 사이에 마스틱 실러(미도시)를 도포하여 루프패널(1)의 센터 하부에 2개의 센터레일(2,3)을 접착한다.A mastic sealer (not shown) is applied between the two center rails 2 and 3 and the roof panel 1 to bond the two center rails 2 and 3 to the lower center of the center of the roof panel 1.

다음 루프패널(2)의 전후방에 마스틱 실러(6)를 이용하여 프런트레일(4)과 리어레일(5)의 내측을 접착한 후 루프페일(1)과 루프패널(2,3,4,5)을 스폿(spot) 용접(7)에 의해 고정한다.Next, the front rail 4 and the inside of the rear rail 5 are bonded to each other using the mastic sealer 6 in front and rear of the roof panel 2, and then the roof fail 1 and the roof panels 2, 3, 4 and 5 ) Is fixed by spot welding (7).

이때 센터레일(2,3)과 루프패널(1) 간에는 각 4개씩 총 8점이 용접되고, 프런트레일(4)과 루프패널(1), 리어레일(5)과 루프패널(1) 사이에는 외측으로 각각 16개씩 총 32점이 용접된다.In this case, a total of eight points are welded between each of the center rails 2 and 3 and the roof panel 1, and the front rail 4 and the roof panel 1, and the rear rail 5 and the roof panel 1, respectively. In total, 32 points are welded, 16 in total.

이와 같이 조립된 루프 조립체를 메인벅(Main Buck: 플로어와 사이드 등을 하나의 차체로 연결하는 작업) 공정에서 사이드 구조와 조립한다.The roof assembly thus assembled is assembled with the side structure in the main buck process.

상기 루프 조립체는 메인벅에서 조립 후 루프레일(4,5) 및 루프패널(1)과의 스폿 용접(7) 과다로 루프패널(1) 변형(앞뒤 용접 뒤틀림)이 일어나고 이로 인하여 굴곡이 발생하여 차체 골격 정도 확보에 어려움을 겪으며, 프런트레일(4)과 루프레 일(5)의 스폿 용접(7)에 의한 루프패널(1)에의 조립으로 루프 강성이 떨어진다.After the roof assembly is assembled in the main buckling, the spot welding (7) between the roof rails (4, 5) and the roof panel (1) is excessive, so that the roof panel (1) deformation (front and rear welding warpage) occurs, which causes bending. It is difficult to secure the degree of the skeleton of the vehicle body, and the rigidity of the roof is inferior due to the assembly of the front rail 4 and the roof rail 5 to the roof panel 1 by spot welding 7.

또한, 프런트레일(4)과 루프패널(1), 리어레일(5)과 루프패널(1) 사이의 내측 접착 부위는 패널(1)과 레일(4,5)이 평행한 구조로 마스틱 실러(6) 접착후 떨어짐이 발생하고 루프의 소음이 발생하는 문제점이 있었다.In addition, the inner side bonding portion between the front rail 4 and the roof panel 1, the rear rail 5 and the roof panel 1 has a structure in which the panel 1 and the rails 4 and 5 are parallel to each other. 6) There was a problem that the fall occurs after the adhesion and the noise of the loop.

본 발명은 상술한 문제점을 해결하기 위하여 안출된 것으로서, 프런트레일과 리어레일을 벤딩 형태로 루프패널과 일체화하여 강성을 증대함으로써 루프 처짐 및 비틀림을 방지할 수 있고, 스폿 용접을 삭제하여 용접 변형이 발생하지 않아 정도를 향상시킬 수 있으며, 마스틱 실러 접촉부위를 반원형으로 포밍하여 동강성(動剛性)을 증대할 수 있는 자동차의 루프 보강구조를 제공하는데 그 목적이 있다.The present invention has been made to solve the above-mentioned problems, by integrating the front rail and the rear rail in the form of a bend with the roof panel to increase the rigidity to prevent loop deflection and torsion, and to eliminate spot welding to eliminate welding deformation It is an object of the present invention to provide a roof reinforcement structure of a vehicle which can improve the degree of occurrence and improve the dynamic rigidity by forming the mastic sealer contact portion in a semicircular shape.

상술한 목적을 달성하기 위한 본 발명에 따른 자동차의 루프 보강구조는, 차체의 천정을 이루는 루프패널과, 상기 루프패널을 보강하기 위해 상기 루프패널의 하부에 소정간격으로 배치되는 루프레일로 이루어지는 자동차의 루프 보강구조에 있어서;A roof reinforcement structure of a vehicle according to the present invention for achieving the above object, a vehicle comprising a roof panel forming a ceiling of a vehicle body, and a roof rail disposed at predetermined intervals under the roof panel to reinforce the roof panel. In the loop reinforcement structure of;

상기 루프패널의 전후 양단부에서 내측으로 벤딩 연장되고 그 연장된 단부가 루프패널의 하부에 마스틱 실러에 의해 접착되어, 상기 루프레일과 폐단면을 이루는 프런트레일과 리어레일이 루프패널에 일체로 형성되는 것을 특징으로 한다.The front and rear rails extending from the front and rear ends of the roof panel inwardly and the extended end thereof are bonded to the lower part of the roof panel by a mastic sealer are integrally formed on the roof panel with the front rail and the rear rail. It is characterized by.

상술한 과제 해결 수단에 의하면 루프의 강성을 증대함으로써 루프 처짐 및 비틀림을 방지할 수 있고, 스폿 용접을 삭제하여 용접 변형이 발생하지 않아 정도를 향상시킬 수 있으며, 마스틱 실러 접촉부위를 반원형으로 포밍하여 동강성을 증대할 수 있다.According to the problem solving means described above, the loop rigidity can be prevented by increasing the stiffness of the loop, the spot welding can be eliminated, and the welding deformation does not occur so that the degree can be improved. Dynamic stiffness can be increased.
