본 발명은 차량의 차체를 구성하는 플로워패널에 관한 것으로, 특히 센터 플로워패널의 터널부 후방에 상하 및 좌우 방향으로의 구조적인 강성을 증대시키는 스테이를 장착한 차량의 플로워패널 보강구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor panel constituting a vehicle body, and more particularly, to a floor panel reinforcement structure of a vehicle equipped with a stay that increases structural rigidity in up, down, left and right directions behind a tunnel portion of a center follower panel.

종래 승용 차량의 차체는 도 1에 도시한 바와 같이 차량의 길이방향을 따라서 연장되게 형성되면서 차체의 중앙에 배치되는 센터 플로워패널(1)을 구비하고 있고, 상기 센터 플로워패널(1)의 좌우방향 중앙에는 상부로 돌출한 터널부(1a)가 형성되며, 상기 터널부에 배기파이프나 추진축 등이 수용되어 장착된다.As shown in FIG. 1, a vehicle body of a conventional passenger vehicle includes a center follower panel 1 disposed in the center of the vehicle body while being formed to extend along a longitudinal direction of the vehicle, and the left and right directions of the center follower panel 1. A tunnel portion 1a protruding upward is formed in the center, and an exhaust pipe, a propulsion shaft, and the like are accommodated in the tunnel portion.

도 2에는 상기 터널부(1a)의 후방 단면이 도시되어 있는 바, 즉 센터 플로워패널(1)의 터널부(1a)는 대체로 사다리꼴 형상으로 돌출되게 절곡되어 형성되고, 상기 터널부(1a)의 상면에는 보강부재(2)가 부착되어 터널부의 강성을 보강하게 되며, 상기 터널부(1a)의 하부에는 터널부(1a)의 좌우 양측 가장자리에 스테이 브라켓(3)이 각각 부착됨과 더불어 상기 스테이 브라켓(3)에 사각 평판형상을 한 스테이(4)가 부착되어 터널부의 강성을 보강하게 되어 있다.2 shows a rear section of the tunnel portion 1a, that is, the tunnel portion 1a of the center follower panel 1 is formed to be bent to protrude in a substantially trapezoidal shape, and the The reinforcing member 2 is attached to the upper surface to reinforce the rigidity of the tunnel part, and the stay bracket 3 is attached to the left and right edges of the tunnel part 1a at the lower part of the tunnel part 1a, and the stay bracket is attached. A stay 4 having a rectangular flat plate is attached to (3) to reinforce the rigidity of the tunnel portion.
