CONSTITUTION: The middle of a center floor is bent, and both sides of the center floor are mounted in side sill inner panels(20,30). Side sill outer panels(40,50) are mounted out of side sill inner panels. A cross member(60) is spaced from the upper part of the center floor, and both ends of the cross member are mounted in side sill inner panels. A reinforcing panel(70) has a tunnel reinforcing part(71) overlapped in the lower part of the staple-shaped bent part in the center floor, and a side reinforcing part(72) inserted to the center floor. Both ends of the reinforcing panel are extended, and jointed in side sill inner panels. The rigidity of the center floor is increased with integrally forming the reinforcing panel in the center floor. The center floor is manufactured and assembled conveniently with reducing parts.

Description

차량의 센터 플로어 보강구조Center floor reinforcement structure of vehicle

본 발명은 차량의 센터 플로어 보강구조에 관한 것으로서, 특히 사이드 멤버, 터널 보강 멤버 및 충격 흡수 멤버를 센터 플로어에 단일체로 형성하여 센터 플로어의 전체적인 강성을 향상시키고, 또 구성 부품의 감소에 따라 조립 및 제작 공정을 대폭 단축함과 동시에 원가를 절감할 수 있도록 한 차량의 센터 플로어 보강구조에 관한 것이다.The present invention relates to a center floor reinforcement structure of a vehicle, and in particular, the side member, the tunnel reinforcement member, and the shock absorbing member are formed in a single unit on the center floor, thereby improving the overall rigidity of the center floor, and assembling and reducing the component parts. The present invention relates to a center floor reinforcement structure of a vehicle that can greatly reduce the manufacturing process and reduce costs.

도 1은 종래의 센터 플로어 보강구조를 나타내는 단면도로서, 센터 플로어(10)의 중간부가 "ㄷ"자형으로 절곡되어 있고, 센터 플로어(10)의 양단에 사이드 실 인너 패널(20),(30)이 접합되어 있으며, 사이드 실 인너 패널(20),(30)에는 사이드 실 아웃터 패널(40),(50)이 접합 설치되어 있다.1 is a cross-sectional view showing a conventional center floor reinforcement structure, wherein an intermediate portion of the center floor 10 is bent into a "c" shape, and side seal inner panels 20 and 30 are formed at both ends of the center floor 10. The side seal inner panels 20 and 30 are bonded to each other, and the side seal outer panels 40 and 50 are bonded to each other.

상기 센터 플로어(10)의 상방에 일정 간격을 갖고 크로스 멤버(60)가 이격 위치되어 그 양단이 사이드 실 인너 패널(20),(30)에 접합되어 있고, 상기 센터 플로어(10)의 중간 절곡부 하방에 대응하여 터널 보강 멤버(100)가 접합 설치되어 있으며, 터널 보강 멤버(100)의 양측에 접하도록 사이드 멤버(110),(120)가 각각 접합 설치되어 있다.Cross members 60 are spaced apart from each other at regular intervals above the center floor 10, and both ends thereof are joined to the side seal inner panels 20 and 30, and intermediate bending of the center floor 10 is performed. Tunnel reinforcement member 100 is joined to correspond to the lower part, and side members 110 and 120 are joined to each other so as to be in contact with both sides of tunnel reinforcement member 100.

그러나, 종래에는 센터 플로어(10)를 보강하기 위해 사이드 멤버(110),(120)나 터널 보강 멤버(100) 등 다수의 보강재들을 필요로 하게 되므로, 구성 부품의 증가에 따른 조립 및 제작공정이 증가하고, 또한 이로 인하여 제품의 원가가 상승되는 단점이 있었다.However, in the related art, since a plurality of reinforcing members such as side members 110 and 120 and tunnel reinforcing member 100 are required to reinforce the center floor 10, an assembly and a manufacturing process according to an increase in component parts are required. In addition, there was also a disadvantage in that the cost of the product increases.

또한, 각각의 보강재들이 센터 플로어(10)를 독자적으로 보강하고 있어 주변 부품과의 연계구조를 통한 강성 강화 측면에서는 다소 미흡한 점이 있었다.In addition, each of the reinforcing materials to reinforce the center floor 10 independently, there was a slight lack in terms of strengthening the rigidity through the linkage structure with the surrounding components.

본 발명의 목적은 구성 부품수를 대폭 감소시켜 조립 및 제작공정을 단축할 수 있고 이에 따라 원가를 절감할 수 있는 차량의 센터 플로어 보강구조를 제공하기 위한 것이다.An object of the present invention is to provide a center floor reinforcement structure of a vehicle that can significantly reduce the number of components and shorten the assembly and fabrication process, thereby reducing the cost.

본 발명의 다른 목적은 본 발명에서 채용하고 있는 보강 패널과 센터 플로어간에 좀더 확실한 결합구조를 도모하면서 주변 부품과의 연계적인 구성을 통해 센터 플로어의 전체적인 구조적 강성을 높일 수 있는 차량의 센터 플로어 보강구조를 제공하기 위한 것이다.Another object of the present invention is to enhance the overall structural rigidity of the center floor through a linkage configuration with peripheral components while promoting a more secure coupling structure between the reinforcement panel and the center floor employed in the present invention. It is to provide.

본 발명은 상기의 목적을 달성하기 위하여 센터 플로어의 중간부를 "ㄷ"자형으로 절곡하고, 센터 플로어의 양단에 사이드 실 인너 패널을 접합하며, 또한 사이드 실 인너 패널에 사이드 실 아웃터 패널을 접합 설치하여 구성한다.In order to achieve the above object of the present invention, the middle portion of the center floor is bent into a "c" shape, the side seal inner panels are bonded to both ends of the center floor, and the side seal outer panels are bonded to the side seal inner panels. Configure.

상기 센터 플로어의 상방에 일정 간격을 갖는 크로스 멤버를 이격 위치시킨 상태에서 그 양단을 사이드 실 인너 패널에 접합하고, 상기 센터 플로어의 중간 절곡부 하방에 대응하여 터널 보강부 및 사이드 보강부를 갖는 일체형의 보강 패널을 구비하고, 이 보강 패널의 양단을 사이드 실 인너 패널의 하방에 접합 설치하여 구성된 것이 특징이다.Both ends are joined to the side seal inner panel in a state in which cross members having a predetermined interval are spaced above the center floor, and an integral type having a tunnel reinforcement part and a side reinforcement part corresponding to the lower side of the middle bent part of the center floor. A reinforcement panel is provided, and both ends of this reinforcement panel are bonded and provided below the side seal inner panel.

이하, 본 발명의 구체적인 실시예를 도면을 참조하여 상세히 설명한다.Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.

도 2는 본 발명의 센터 플로어 보강구조를 나타내는 단면도이다.2 is a cross-sectional view showing the center floor reinforcement structure of the present invention.

도 2에 도시한 바와 같이, 센터 플로어(10)의 중간부를 "ㄷ"자형으로 절곡하고, 센터 플로어(10)의 양단에 사이드 실 인너 패널(20),(30)을 접합하며, 또한 사이드 실 인너 패널(20),(30)의 바깥쪽에 사이드 실 아웃터 패널(40),(50)을 접합 설치하여 구성한다.As shown in FIG. 2, the middle portion of the center floor 10 is bent into a "c" shape, and the side seal inner panels 20 and 30 are bonded to both ends of the center floor 10, and the side seals are also bonded. The side seal outer panels 40 and 50 are bonded to and installed on the outer side of the inner panels 20 and 30.

또한, 상기 센터 플로어(10)의 상방에 일정 간격을 갖도록 크로스 멤버(60)를 이격 위치시킨 상태에서 그 양단을 사이드 실 인너 패널(20),(30)에 접합한다.Further, both ends of the cross member 60 are joined to the side seal inner panels 20 and 30 in a state where the cross member 60 is spaced apart from each other so as to have a predetermined distance above the center floor 10.

특히, 상기 센터 플로어(10)에 있는 "ㄷ"자형 절곡부의 하부에 중첩되는 터널 보강부(71)와, 상기 센터 플로어(10)와의 사이에 삽입되어 일정 간격을 유지해주는 사이드 보강부(72)로 이루어진 보강 패널(70)을 구비하고, 이 보강 패널(70)의 양단을 양편으로 길게 연장하여 사이드 실 내측 패널(20),(30)에 접합시킨다.In particular, the side reinforcement portion 72 is inserted between the tunnel reinforcement portion 71 overlapping the lower portion of the "c" -shaped bent portion in the center floor 10 and the center floor 10 to maintain a predetermined distance The reinforcement panel 70 which consists of these is provided, and both ends of this reinforcement panel 70 are extended to both sides, and it is joined to the side seal inner panel 20,30.

따라서, 본 발명의 센터 플로어 구조에서는 센터 플로어에 중첩되는 터널 보강부 및 센터 플로어와의 사이에 삽입되어 지지력을 발휘하는 사이드 보강부로 구성되는 보강 패널을 일체 조합시키는 동시에 사이드 실 인너 패널과도 연계적으로 구성함으로써, 센터 플로어를 보다 견고하게 보강하여 강성을 증대시킬 수 있으며, 아울러 센터 플로어의 보강을 위해 필요한 구성 부품수가 감소되어 조립 및 제작을 용이하게 할 수 있다.Accordingly, in the center floor structure of the present invention, a reinforcement panel composed of a tunnel reinforcement portion overlapping the center floor and a side reinforcement portion inserted between the center floor and exerting a bearing force is integrally combined with the side seal inner panel. In this configuration, the center floor can be more firmly reinforced to increase rigidity, and the number of components required for reinforcement of the center floor can be reduced to facilitate assembly and fabrication.

이상과 같이 본 발명은 센터 플로어의 보강을 위한 구성 부품수가 대폭 감소됨에 따라 조립 및 제작공정이 단축되고, 제품의 원가가 절감되는 효과와, 센터 플로어측에 견고히 조합되는 구조적 특성으로 인해 전체적인 구조적 강성이 강화되는 효과를 갖는다.As described above, according to the present invention, as the number of components for reinforcement of the center floor is greatly reduced, the assembly and manufacturing process are shortened, the cost of the product is reduced, and the structural characteristics are firmly combined due to the structural characteristics firmly combined with the center floor. This has the effect of being strengthened.
