Abstract

PURPOSE: Fixing structure for the reinforcement bracket of a roof side rail is provided to enhance shock absorbing ability by welding a door opening portion into the inner rail of a side rail and by fixing the other portion with bolts. CONSTITUTION: A shock absorbing reinforcement bracket(30) is fixed between an inner rail(12) of a side rail and the inner panel of a roof. The door opening portion of the reinforcement bracket is welded into one end of the inner rail with an outward bent welding end(31). An outer panel(1) of the roof is fixed to the inner rail using bolts(35) with an inward bent end(32). In this structure, both ends are not necessary to weld into the inner rail of the side rail and the fixing structure is well-crushed caused by the clearance of a bolting groove(33a) to absorb shock better.

Description

루프 사이드레일의 보강브라켓 고정구조 {STRUCTURE FIXING REINFORCEMENT BRACKET OF ROOF SIDE RAIL}Reinforcement bracket fixing structure of roof side rail {STRUCTURE FIXING REINFORCEMENT BRACKET OF ROOF SIDE RAIL}

본 발명은 자동차의 루프 사이드레일의 보강브라켓에 관한 것으로서, 보다 상세하게는 충격흡수용 보강브라켓의 고정에 있어서 도어 오픈닝부측은 사이드레일의 이너레일에 용접을 행하여 고정하고, 타측은 다수곳에 볼팅홈을 형성하여 볼트를 사용하여 고정되게 하므로써, 장착의 편의와 충격시 잘 찌그러지는 것에 의한 충격흡수성이 향상되는 루프 사이드레일의 보강브라켓 고정구조에 관한 것이다.The present invention relates to a reinforcement bracket of a roof side rail of a vehicle, and more particularly, in the fixing of a shock absorbing reinforcement bracket, the door opening part is fixed by welding to the inner rail of the side rail, and the other side is bolted in many places. It relates to a fixed structure of the reinforcing bracket of the roof side rail by forming a bolt to be fixed by using a bolt, thereby improving the convenience of mounting and the shock absorbency by crushing during impact.

일반적으로 자동차의 루프 사이드레일 어셈블리는 차체의 양측 도어 상부에 차량의 길이 방향으로 배치되어 루프를 지지하는 역할을 한다.In general, the roof side rail assembly of the vehicle is disposed in the longitudinal direction of the vehicle on both side doors of the vehicle body to support the roof.

이러한 루프 사이드레일 어셈블리는 도 1에 도시된 바와 같이, 아웃터레일(11)과, 이너레일(12)을 포함하며, 이러한 사이드레일(10)은 그 일단이 루프의 아웃터패널(1)에 접합되고, 타단이 라이닝(3)의 일단에 접합되며, 상기 라이닝(3)의 의 타단에는 상기 루프의 아웃터패널(1)과 이격설치된 루푸의 이너패널(2)이 접합된다.This loop side rail assembly includes an outer rail 11 and an inner rail 12, as shown in FIG. 1, and one end of the side rail 10 is joined to the outer panel 1 of the loop. The other end is joined to one end of the lining 3, and the outer panel 1 of the loop and the inner panel 2 of the loop installed at the other end of the lining 3 are joined to each other.

즉 이격설치된 루프의 아웃터패널(1)과 이너패널(2) 사이에 형성된 중공부에 의해 차량의 측방 충격시 아웃터패널(1)의 침입을 가능케 하여 측방 충격을 흡수하게 되며, 또한 사이드레일(10)에 의해 차량의 루프는 본연의 보강기능을 유지하게 되는 것이다.That is, the hollow part formed between the outer panel 1 and the inner panel 2 of the spaced-in loop enables the outer panel 1 to invade during side impact of the vehicle, thereby absorbing the side impact, and the side rail 10 The roof of the vehicle maintains its original reinforcement function.

그러나, 이러한 루프 사이드레일 어셈블리 구조는 아웃터패널(1)과 인너패널(2)이 접합되어 이루는 중공부의 거리가 멀기 때문에, 측방 충격력에 대한 저항력이 작으므로 측방 충격력을 충분히 흡수하지 못하게 되며, 이 충격력에 의하여 발생되는 차체의 침입량을 감소시키지 못하여 업퍼인테리어에 대한 승차자의 안전을 제대로 보호하지 못하게 되어 상해치를 크게 줄일 수 없게 되는 등의 문제점을 안고 있었다.However, since the loop side rail assembly structure has a long distance between the hollow part formed by joining the outer panel 1 and the inner panel 2, the resistance to the side impact force is small so that the side impact force cannot be sufficiently absorbed. There was a problem such as not being able to reduce the intrusion amount of the vehicle body caused by the inability to properly protect the occupant's safety for the upper interior, greatly reducing the injury value.

이러한 문제점을 해결하기 위하여 종래에는 도 2에서와 같이 사이드레일(10)의 이너레일(12)과 루프의 이너패널(2) 사이에 별도의 보강브라켓(20)을 개재 장착하여 그 충격흡수 및 사이드레일(10)의 보강기능을 향상되게 하였다.In order to solve this problem, as shown in FIG. 2, a separate reinforcing bracket 20 is interposed between the inner rail 12 of the side rail 10 and the inner panel 2 of the loop to absorb the shock and the side. The reinforcement function of the rail 10 was improved.

그런데 이러한 보강브라켓(20)의 고정은 그 양단부가 사이드레일(10)의 이너레일(12)에 스폿용접을 행하여 고정되는 구조를 이루게 되어 길이방향으로 다수곳에 스폿용접을 행하게 되는 어려움과 함께, 특히 충격발생시 상기 보강브라켓(20)의 견고한 용접고정에 따른 찌그러짐이 발생하지 않게 되어 충격흡수가 잘 이루어지지 않게 되는 폐단이 있었다.However, the fixing of the reinforcing bracket 20 has a structure in which both ends thereof are fixed by performing spot welding on the inner rail 12 of the side rail 10, with the difficulty of spot welding at a plurality of places in the longitudinal direction, in particular. When the impact occurs, there is no crushing due to the rigid welding fixation of the reinforcing bracket 20, there was a closed end that the shock absorption is not made well.

본 발명은 전기한 종래의 루프 사이드레일 보강브라켓의 고정구조가 안고 있는 문제점을 해결하기 위하여 안출된 것으로서, 본 발명의 목적은 사이드레일과 루프의 이너패널 사이의 장착되는 충격흡수용 보강브라켓의 고정에 있어서, 도어 오픈닝부측은 사이드레일의 이너레일에 용접을 행하여 고정하고, 타측은 다수곳에 볼팅홈을 형성하여 볼트를 사용하여 고정되게 하므로써, 장착의 편의와 충격시 잘 찌그러지는 것에 의한 충격흡수성이 향상되는 루프 사이드레일의 보강브라켓 고정구조를 제공하는데 있다.The present invention has been made to solve the problem of the conventional fixed structure of the roof side rail reinforcement bracket, the object of the present invention is the fixing of the shock absorbing reinforcement bracket mounted between the side rail and the inner panel of the roof. In the door opening part side is fixed by welding to the inner rail of the side rail, while the other side is formed with bolting grooves in a number of places to be fixed by using a bolt, the convenience of mounting and shock absorption due to crushing well during impact It is to provide a reinforcing bracket fixing structure of the roof side rail to be improved.
