자동차의 루프 보강구조{Roof reinforcing structure of car}Roof reinforcing structure of car}

본 발명은 자동차의 루프 보강구조에 관한 것으로서, 보다 상세하게는 바디의 경량화가 중요한 과제로 제시되고 있는 상황에서, 바디 중 루프패널의 경량화 대책으로 루프패널을 플라스틱재로 구성함과 동시에 기존의 프론트 레일과 리어 레일은 그대로 두고, 단지 센터 레일의 일부를 격자형의 리브로 대체함으로써 루프패널의 강성을 보강할 수 있는 자동차의 루프 보강구조에 관한 것이다.The present invention relates to a roof reinforcement structure of an automobile. More specifically, in a situation in which weight reduction of the body is proposed as an important task, the roof panel is made of plastic material and the front of the existing front panel is used as a countermeasure to reduce the weight of the roof panel among the bodies. The present invention relates to a roof reinforcement structure of a vehicle that can reinforce the rigidity of the roof panel by replacing a portion of the center rail with lattice ribs while leaving the rail and the rear rail intact.

최근에는 지구환경을 보호하는 차원에서 이산화탄소를 적게 배출하는 위하여엔진의 연비효율의 개선을 서두르고 있다. 그의 효과적인 수단의 하나로 차량의 경량화가 중요한 과제로 대두되고 있다.Recently, in order to protect the global environment, in order to emit less carbon dioxide, the engine is rushing to improve fuel efficiency. As an effective means, weight reduction of vehicles has emerged as an important task.

바디는 차량중량의 약 30%를 점하고 있기 때문에 그의 경량화의 효과는 매우 크다. 재료에 의한 바디의 경량화 대책의 대표적인 것 중의 하나는 플라스틱의 채용이다.Since the body occupies about 30% of the weight of the vehicle, its weight reduction effect is very large. One of the typical measures to reduce the weight of the body by the material is the use of plastic.

루프 바디의 외판을 플라스틱으로 대체할 경우, 경량화, 내 부식성, 내 덴트성, 외관향상 등의 여러 가지 장점을 갖게 된다.When the outer shell of the roof body is replaced with plastic, it has various advantages such as light weight, corrosion resistance, dent resistance, and appearance improvement.

도 1은 종래 스틸재의 루프 패널을 보인 분리 사시도로서, 루프패널(1)의 양측에는 사이드 패널(2)이 위치되고, 루프패널(1)의 저면 전방과 후방에는 프론트 레일(3)과 리어 레일(4)이 설치된다.1 is an exploded perspective view showing a roof panel of a conventional steel, in which side panels 2 are positioned at both sides of the roof panel 1, and front rails 3 and rear rails are located at the front and rear of the bottom of the roof panel 1. (4) is installed.

루프패널(1)의 저면 중간에는 보강을 위해서 다수의 센터 레일(5,6,7)이 차폭방향으로 용접되어 있다.In the middle of the bottom face of the roof panel 1, many center rails 5, 6, 7 are welded in the vehicle width direction for reinforcement.

프론트 레일(3)은 A필러 측에, 리어 레일(4)은 C필러 측에, 센터레일(5,6,7) 중 하나는 B필러 측에 용접되어 BIW 골격 전체의 강성 및 강도를 확보하는 데 쓰인다.The front rail 3 is welded to the A-pillar side, the rear rail 4 to the C-pillar side, and one of the center rails 5, 6 and 7 is welded to the B-pillar side to secure rigidity and strength of the entire BIW skeleton. Used to

그리고, B필러와 용접되지 않은 나머지 센터레일은 국부적으로 루프패널(1)의 강성을 확보하여 루프패널의 처짐 및 진동을 방지하는 역할만을 한다.And, the remaining center rail not welded with the B-pillar locally serves only to secure the rigidity of the roof panel 1 to prevent sagging and vibration of the roof panel.

전술한 바와 같이, 종래 루프패널에서는, 강성 및 강도 확보를 위해서 다수개의 센터레일이 사용되고 있으나, 많은 센터 레일의 사용은 차체의 경량화를 어렵게 할 뿐만 아니라 원가상승의 요인을 유발한다.As described above, in the conventional roof panel, a plurality of center rails are used to secure rigidity and strength, but the use of many center rails not only makes the weight of the vehicle difficult but also causes a cost increase.

따라서, 센터 레일의 갯수를 감소시키면서도 루프패널의 강성을 유지할 수 있는 기술의 필요성이 절실히 요구되고 있다.Therefore, there is an urgent need for a technology capable of maintaining the rigidity of the roof panel while reducing the number of center rails.

본 발명은 상술한 바와 같은 문제점을 해결하기 위하여 제안된 것으로, 바디 중 루프패널의 경량화 대책으로 루프패널을 플라스틱재로 함과 동시에 기존의 프론트 레일과 리어 레일은 그대로 두고, 단지 센터 레일의 일부를 격자형의 리브로 대체함으로써 루프패널의 강성을 보강할 수 있는 자동차의 루프 보강구조를 제공함에 그 목적이 있다.The present invention has been proposed in order to solve the above problems, and to reduce the weight of the roof panel of the body, the roof panel is made of plastic and the existing front rail and the rear rail are left as it is, and only a part of the center rail is left. It is an object of the present invention to provide a roof reinforcement structure of a vehicle that can reinforce the rigidity of the roof panel by replacing the lattice ribs.

상기의 목적을 달성하기 위하여 본 발명은, 플라스틱 루프패널의 저면 전방에는 프론트 레일이 설치되고, 후방에는 리어 레일이 설치되며, 중간에는 격자형의 리브가 다수 설치된다.In order to achieve the above object, the present invention, the front rail is installed in front of the bottom surface of the plastic roof panel, the rear rail is installed in the rear, a plurality of grid-shaped ribs are installed in the middle.

즉, 바디의 경량화가 중요한 과제로 제시되고 있는 상황에서, 바디 중 루프패널의 경량화 대책으로 루프패널을 플라스틱으로 함과 동시에 기존의 프론트 레일과 리어 레일은 그대로 하고, 단지 센터 레일의 일부를 격자형의 리브로 대체함으로써 루프패널의 강성을 보강할 수 있도록 구성된다.In other words, in the situation where the weight reduction of the body is proposed as an important task, the roof panel is made of plastic and the existing front rail and the rear rail are left intact, and only a part of the center rail is lattice type. It is configured to reinforce the stiffness of the roof panel by replacing with ribs.

이하, 첨부된 도면을 참조하여 본 발명의 특징적인 구성을 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings will be described a characteristic configuration of the present invention.

도 2는 본 발명에 따른 자동차의 루프 보강구조를 보인 분리 사시도이고, 도 3은 본 발명의 요부발췌 확대 사시도이다.Figure 2 is an exploded perspective view showing a roof reinforcement structure of the vehicle according to the invention, Figure 3 is an enlarged perspective view of the main portion of the present invention.

도 2 내지 도 3에 도시된 바와 같이, 바디의 경량화가 중요한 과제로 제시되고 있는 상황에서, 바디 중 루프패널의 경량화 대책으로 루프패널(1)을 플라스틱으로 함과 동시에 기존의 프론트 레일(3), 리어 레일(4), 사이드 패널(2) 그리고 센터 레일 중 제 2,3레일(6,7)은 종래와 동일한 구성으로 그대로 두고, 단지 나머지 센터 레일을 격자형의 리브(100)로 대체함으로써 루프패널(1)의 강성을 보강할 수 있도록 구성된다. 상기 리브(100)는 루프패널(1)과 독립적으로 이루어지는 구성부품이 아니라 루프패널(1)과 함께 일체로 구성되는 부품이다.As shown in Figs. 2 to 3, in the situation where the weight reduction of the body is proposed as an important problem, the front panel 3 is made of the roof panel 1 and the plastic at the same time as a measure to reduce the weight of the roof panel among the bodies. The second and third rails 6 and 7 of the rear rail 4, the side panel 2 and the center rail are left in the same configuration as before, and only the remaining center rails are replaced with lattice ribs 100. It is configured to reinforce the rigidity of the roof panel (1). The rib 100 is not a component that is formed independently of the roof panel 1, but a component that is integrally formed with the roof panel 1.

여기서, 프론트 레일(3), 리어 레일(4), 그리고 다른 센터레일(6,7)은 사이드 패널(2)에 먼저 조립되고, 그 다음 루프패널(1)이 조립된다. 조립 시, 루프패널(1)에 에폭시 계열의 접착제를 도포시켜 접착시킨다.Here, the front rail 3, the rear rail 4, and the other center rails 6, 7 are assembled to the side panel 2 first, and then the roof panel 1 is assembled. At the time of assembly, the adhesive is applied by applying an epoxy-based adhesive to the roof panel (1).

도 3을 참조하여 리브의 구성을 살펴보면, 리브(100)는 종 방향과 횡 방향의 격막이 엇갈려 이루어진 형상으로, 리브(100)와 리브(100) 사이에 공간부(100a)를 이루고 있다. 상기 공간부(100a)를 두는 이유는 차체의 경량화를 실현하면서도 강성을 유지할 수 있기 때문이다.Looking at the configuration of the ribs with reference to Figure 3, the rib 100 has a shape in which the diaphragm in the longitudinal direction and the transverse direction is crossed, forming a space portion (100a) between the rib 100 and the rib (100). The reason why the space portion 100a is provided is that the rigidity can be maintained while the weight of the vehicle body is reduced.

상기 리브(100)는 LPMC 재료로 이루어져 있고 비중은 2.0이며, 불포화 폴리에스터와 유리섬유 그리고 충진제로 이루어지는 것이 바람직하다.The rib 100 is made of LPMC material and has a specific gravity of 2.0, preferably made of unsaturated polyester, glass fiber, and filler.

본 발명은, 플라스틱 루프패널(1)의 저면 전방에는 프론트 레일(3)이 설치되고, 후방에는 리어 레일(4)이 설치되며, 중간에는 격자형의 리브(100)가 다수 설치됨으로써, 루프 패널의 강성을 증대시킬 수 있다.According to the present invention, the front rail 3 is installed in front of the bottom of the plastic roof panel 1, the rear rail 4 is installed in the rear, and a plurality of lattice ribs 100 are installed in the middle, thereby providing a roof panel. Can increase the rigidity.

또한, 본 발명은 센터 레일(5,6,7) 중 하나의 센터 레일(5: 도 1참조)만을삭제하고, 이 센터 레일(5)대신에 리브(100)를 설치한 구성을 실시 예로 설명하고 있으나, 차종에 따라서는 달라질 수 있다. 즉, 세단의 경우 세 개의 센터 레일 모두를 리브로 대체할 수도 있는 것이다.In addition, this invention removes only the center rail 5 (refer FIG. 1) among the center rails 5, 6, and 7, and the rib 100 is provided instead of this center rail 5, and it demonstrates by the Example. However, it may vary depending on the model. In other words, the sedan could replace all three center rails with ribs.

이상에서 살펴본 바와 같이, 본 발명은 루프패널(1)의 재질을 스틸에서 플라스틱으로 단순하게 변경하는 정도의 구성이 아니라, 플라스틱 루프패널을 채택함으로써 경량화를 실현함과 동시에 루프패널 저면 중간에는 센터 레일 일부를 삭제하는 대신 그 곳에 격막 형상을 갖는 리브를 형성함으로써 루프패널의 강성을 확보하면서도 불필요없는 부품을 삭제할 수 있는 것이다.As described above, the present invention is not a configuration that simply changes the material of the roof panel 1 from steel to plastic, and realizes light weight by adopting the plastic roof panel and at the same time the center rail in the middle of the roof panel bottom. Instead of deleting a part, a rib having a diaphragm shape is formed there, thereby securing unnecessary rigidity while securing rigidity of the roof panel.

상술한 바와 같이 본 발명은, 바디의 경량화가 중요한 과제로 제시되고 있는 상황에서, 바디 중 루프패널의 경량화 대책으로 루프패널을 플라스틱재로 함과 동시에 기존의 프론트 레일과 리어 레일은 그대로 두고, 단지 센터 레일의 일부를 격자형의 리브로 대체함으로써 루프패널의 강성을 보강할 수 있어 내 부식성, 내 덴트성을 높일 수 있다.As described above, in the situation where the weight reduction of the body is proposed as an important problem, the present invention provides a roof panel made of plastic material as a countermeasure to reduce the weight of the roof panel among the bodies, and the existing front rail and the rear rail are left alone. By replacing part of the center rail with lattice ribs, the stiffness of the roof panel can be reinforced to increase corrosion resistance and dent resistance.

또한, 본 발명은 부품 및 공정 수를 줄여서 생산성 및 생산원가를 줄일 수 있다.In addition, the present invention can reduce the number of parts and processes to reduce productivity and production costs.
