자동차의 플로어패널구조{floor panel structure of vehicle}Floor panel structure of vehicle

본 발명은 자동차의 플로어패널구조에 관한 것으로, 특히 머플러파이프가 통과하는 터널부의 강성을 증대시켜 전체적인 플로어패널의 횡방향 강성을 향상시킬 수 있도록 된 자동차의 플로어패널구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor panel structure of a vehicle, and more particularly, to a floor panel structure of a vehicle that is capable of improving the stiffness of the entire floor panel by increasing the rigidity of the tunnel portion through which the muffler pipe passes.

일반적으로, 차량의 플로어패널(10)은 도 1 내지 도 3에 도시된 바와 같이 운전석과 조수석을 지탱하는 프런트플로어패널(11)와, 뒷좌석을 지탱하는 센터플로어패널(12) 및, 연료탱크가 고정되면서 트렁크룸을 형성하는 리어플로어패널(13)의 결합으로 구성되어 있다.Generally, the floor panel 10 of the vehicle includes a front floor panel 11 supporting a driver's seat and a passenger seat, a center floor panel 12 supporting a rear seat, and a fuel tank, as shown in FIGS. It is composed of a combination of the rear floor panel 13 to form a trunk room while being fixed.

여기서, 상기 플로어패널(10)의 중간부위에는 머플러파이프(20)가 통과하는 터널부(10a)가 일체로 구비되는데, 상기 터널부(10a)는 그 양단이 차체의 길이방향으로 형성되고 또한 그 윗면은 실내쪽으로 돌출되면서 굴곡지게 형성되어 있다.Here, the tunnel portion 10a through which the muffler pipe 20 passes is integrally provided at an intermediate portion of the floor panel 10, and both ends of the tunnel portion 10a are formed in the longitudinal direction of the vehicle body. The upper surface is curved to protrude toward the interior.

그리고, 상기 센터플로어패널(12)의 윗면에는 프런트시트(도시않됨)의 강성을 보강하는 프런트시트크로스멤버(30)가 용접에 의해 일체로 접합되어 설치되는데, 상기 프런트시트크로스멤버(30)는 그 양단이 차체의 폭을 따라 센터플로어패널(12)을 횡축방향으로 가로지르면서 설치되는 구조로 되어 있다.In addition, the front seat cross member 30, which reinforces the rigidity of the front seat (not shown), is integrally joined to the upper surface of the center floor panel 12 by welding, and the front seat cross member 30 is installed. Both ends thereof are provided while crossing the center floor panel 12 in the horizontal axis direction along the width of the vehicle body.

또한, 상기 센터플로어패널(12)의 윗면에 프런트시트크로스멤버(30)가 설치됨으로써 상기 센터플로어패널(12)과 프런트시트크로스멤버(30)사이에는 일정용적의 밀폐공간(A,B)이 형성되는데, 이 밀폐공간(A,B)은 상기 센터플로어패널(12)과 프런트시트크로스멤버(30)의 접합구조에 따라 터널부(10a)를 중심으로 양측부위에만 형성되게 되고 상기 터널부(10a)의 위쪽으로는 형성되지 않는 구조로 되어 있다.In addition, the front seat cross member 30 is installed on the upper surface of the center floor panel 12, so that a certain volume of sealed spaces A and B is formed between the center floor panel 12 and the front seat cross member 30. The sealed spaces A and B are formed only at both sides of the tunnel portion 10a according to the junction structure of the center floor panel 12 and the front seat cross member 30, and the tunnel portion ( It is a structure not formed above 10a).

한편, 상기 센터플로어패널(12)의 양측단과 프런트시트크로스멤버(30)의 양단은 각각 사이드실인너패널(41,42)과 용접에 의해 면접합되어 결합되는 구조로 되어 있고, 상기 사이드실인너패널(41,42)은 그 양단이 사이드실아웃터패널(43,44)과 각각 용접에 의해 접합되면서 상기 사이드실인너패널(41,42)과 사이드실아웃터패널(43,44)사이에는 일정용적의 밀폐공간이 형성되는 구조로 되어있다.On the other hand, both ends of the center floor panel 12 and both ends of the front seat cross member 30 has a structure in which the side seal inner panels (41, 42) are joined to each other by welding, the side seal inner Both ends of the panels 41 and 42 are joined to the side seal outer panels 43 and 44 by welding, respectively, and a predetermined volume is formed between the side seal inner panels 41 and 42 and the side seal outer panels 43 and 44. The closed space of the structure is formed.

그러나, 전술한 바와 같이 상기 프런트시트크로스멤버(30)가 센터플로어패널(12)의 윗면에 접합됨으로써 센터플로어패널(12)과 프런트시트크로스멤버(30)사이에 형성되는 밀폐공간(A,B)이 터널부(10a)를 중심으로 양측부위에만 형성되고 상기 터널부(10a)의 위쪽으로는 형성되지 않게 됨으로써, 상기 터널부(10a)의 강성이 프런트시트크로스멤버(30)가 접합되는 센터플로어패널(12)의 다른 부위보다 상대적으로 취약하다는 문제점이 있었다.However, as described above, the front seat cross member 30 is bonded to the upper surface of the center floor panel 12 to form a sealed space formed between the center floor panel 12 and the front seat cross member 30. ) Is formed only at both sides of the tunnel portion 10a and not formed above the tunnel portion 10a, so that the rigidity of the tunnel portion 10a is joined to the front seat cross member 30. There was a problem in that it is relatively weaker than other parts of the floor panel 12.

즉, 상기 터널부(10a)의 윗면에는 도 3에 도시된 바와 같이 박스폐단면의 밀폐구조가 형성되지 않게 되며, 이로 인해 박스폐단면의 밀폐공간(A,B)이 형성되는 양쪽 측면부위보다 상대적으로 강성이 취약해지게 되는 것이다.That is, as shown in FIG. 3, the closed structure of the box closed end surface is not formed on the upper surface of the tunnel portion 10a, and thus, the side surfaces of the closed spaces A and B of the closed box closed side are formed. The stiffness becomes relatively weak.

이에 따라, 측면충돌사고가 발생되면 상기 밀폐공간(A,B)이 형성된 센터플로어패널(12)의 양측면부는 그 충격력을 최대한 감소시키면서 찌그러지는 변형이 최소화되게 되지만, 밀폐공간이 형성되지 않은 상기 터널부(10a)는 충격력의 대부분을 전달받아 심하게 찌그러지는 변형이 일어나면서 머플러파이프(20)를 훼손시키는 문제점이 있었다.Accordingly, when a side collision accident occurs, both side portions of the center floor panel 12 in which the sealed spaces A and B are formed are minimized to minimize the deformation while reducing the impact force, but the tunnel is not formed. Part 10a has a problem that damages the muffler pipe 20 while the deformation is severely distorted by receiving most of the impact force.

이에 본 발명은 상기와 같은 문제점을 해소하기 위해 안출된 것으로, 터널부의 아래쪽으로 보강패널을 설치하여 상기 터널부의 강성을 증대시킴으로써, 측면충돌사고 발생시 충격력에 의한 상기 터널부의 변형을 최소화시키면서 머플러파이프의 손상을 최대한 예방할 있도록 된 자동차의 플로어패널구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, by installing a reinforcement panel under the tunnel portion to increase the rigidity of the tunnel portion, while minimizing the deformation of the tunnel portion due to the impact force in the event of a side collision accident of the muffler pipe The object is to provide a floor panel structure of a vehicle that is capable of preventing damage as much as possible.

상기와 같은 목적을 달성하기 위한 본 발명의 플로워패널구조는, 머플러파이프가 설치되는 터널부를 구비한 센터플로어패널과, 이 센터플로어패널을 횡축방향으로 가로지면서 상기 터널부의 양측으로 밀폐공간이 형성되도록 설치되는 프런트시트크로스멤버와, 상기 터널부와 머플러파이프사이에 위치되면서 터널부의 아래쪽으로 밀폐공간이 형성되게 양단이 상기 센터플로어패널의 밑면에 접합되어 설치되는 보강패널을 포함하여 이루어지는 것을 특징으로 한다.The floor panel structure of the present invention for achieving the above object, the center floor panel having a tunnel portion, the muffler pipe is installed, and the center floor panel while crossing the center floor panel in the transverse direction so that the closed space is formed on both sides of the tunnel portion It is characterized in that it comprises a front seat cross member is installed between the tunnel portion and the muffler pipe and both ends are joined to the bottom surface of the center floor panel to form a sealed space below the tunnel portion. .
