Description

자동차용 중앙 바닥패널 구조{Center floor panel structure for automobile}Center floor panel structure for automobile}

본 발명은 자동차용 중앙 바닥패널 구조에 관한 것으로, 더욱 상세하게는 자동차용 시트 및 시트 밸트 고정부가 견고히 고정되고, 그 하부에 장착된 연료 탱크가 견고히 지지되는 중앙 바닥패널 구조에 관한 것이다.The present invention relates to a center floor panel structure for an automobile, and more particularly, to a center floor panel structure in which an automobile seat and seat belt fixing unit is firmly fixed and a fuel tank mounted under the vehicle is firmly supported.

널리 알려진 바와 같이, 도 1에 도시된 자동차용 시트 배열도는 각각의 시트가 장착되는 바닥패널을 구비한다. 첫번째 열의 시트(100)는 전방 바닥패널(110)에장착되며, 두번째열의 시트(200)는 중앙 바닥패널(210)에 장착되고, 세번째 열의 시트(300)은 후방 바닥패널(310)에 장착된다.As is well known, the automobile seat arrangement diagram shown in FIG. 1 has a bottom panel on which each seat is mounted. The first row of seats 100 is mounted on the front bottom panel 110, the second row of seats 200 is mounted on the center bottom panel 210, and the third row of seats 300 is mounted on the rear bottom panel 310. .

종래의 자동차용 중앙 바닥패널 구조는, 도 2에 도시된 바와 같이, 중앙 바닥패널(1)과, 제 1 보강부재(2)와, 제 2 보강부재(3)와, 크로스 부재(4)을 포함한다.Conventional vehicle center floor panel structure, as shown in Figure 2, the center bottom panel 1, the first reinforcing member (2), the second reinforcing member (3), cross member (4) Include.

중앙 바닥패널(1)의 하부에는 완충제가 씌워진 연료 탱크(8)가 위치되고, 중앙 바닥패널(1)의 상부에 크로스 부재(4)의 각 단부가 용접에 의해 고정되고, 중앙 바닥패널(1)과 크로스 부재(4) 사이의 용접점의 이탈을 방지하기 위하여 중앙 바닥패널(1)과 크로스 부재(4)가 용접된 단부의 상측에 제 1 보강부재(2)가 용접에 의해 고정되며, 중앙 바닥패널(1)과 크로스 부재(4)가 용접된 부분의 하측에 제 2 보강부재(3)가 결합된다. 또한, 자동차용 시트(미도시)가 수평으로 안정적으로 장착되기 위해 크로스 부재(4)의 전방에 별도의 폼 블럭(foam block, 5)이 장착되어, 차체 하부를 평평하게 한다. 중앙 바닥패널(1)의 상부에 크로스 부재(4)와 폼블럭(5)이 장착되면, 그 위에 시트 매트(7)가 덮여진 후에, 시트 및 시트 벨트 고정부(미도시)가 장착된다.A fuel tank 8 covered with a buffer is positioned below the center bottom panel 1, and each end of the cross member 4 is fixed to the top of the center bottom panel 1 by welding, and the center bottom panel 1 The first reinforcing member 2 is fixed to the upper side of the end where the center bottom panel 1 and the cross member 4 are welded to prevent separation of the welding point between the cross member 4 and the cross member 4, The second reinforcing member 3 is coupled to the lower side of the portion where the center bottom panel 1 and the cross member 4 are welded. In addition, a separate foam block 5 is mounted in front of the cross member 4 so that the vehicle seat (not shown) can be horizontally and stably mounted, thereby flattening the lower portion of the vehicle body. When the cross member 4 and the foam block 5 are mounted on the upper part of the center bottom panel 1, after the seat mat 7 is covered thereon, the seat and seat belt fixing parts (not shown) are mounted.

이러한 종래의 중앙 바닥패널 구조는 중앙 바닥패널이 연료 탱크를 지지하도록 연료 탱크의 형상에 상응하도록 성형됨으로써, 하부에 별도의 폼 블럭이 필요하여 조립 공정 및 조립 시간이 많이 소요되어 제조 단가가 상승하는 문제점이 있었다.The conventional center bottom panel structure is formed to correspond to the shape of the fuel tank so that the center bottom panel supports the fuel tank, so that a separate foam block is required at the bottom thereof, which requires a lot of assembly processes and assembly time, thereby increasing manufacturing costs. There was a problem.

또한, 시트 및 시트 밸트 고정부가 고정되는 크로스 부재가 바닥패널의 상부, 즉, 차실 내에 있게 되어 시트 및 시트 벨트 고정부의 인장 시험(seat and seat belt anchorage test)중에 하중을 견디지 못하여 크로스 부재의 용접점이 이탈되어 차체 변형이 크게 발생하는 문제점이 있었다.In addition, the cross member to which the seat and seat belt fixing parts are fixed is located at the top of the bottom panel, i.e., in the cabin, so that the welding of the cross member is not possible to withstand the load during the seat and seat belt anchorage test. There was a problem that the deformation of the vehicle greatly occurs due to the deviation from the point.

본 발명은 이러한 종래의 기술의 문제점을 해결하기 위해 안출한 것으로, 별도의 폼 블럭이 필요없어 조립 공정이 용이하여 제조 단가가 낮으며, 시트 및 시트 벨트 고정부가 견고히 고정되는 자동차용 중앙 바닥패널 구조를 제공하는 데 그 목적이 있다.The present invention has been made in order to solve the problems of the prior art, the need for a separate foam block is easy to assemble process is low manufacturing cost, the central floor panel structure for automobile that the seat and seat belt fixing part is firmly fixed The purpose is to provide.
