Abstract
A tunnel reinforcing structure includes a floor cross member that extends in a vehicle width direction and that couples a side sill on each side of the vehicle and a floor tunnel to each other, the floor tunnel being a tunnel in which an exhaust pipe is arranged in a tunnel interior opened toward the lower external side of a vehicle, seat brackets that are arranged in front of and behind the cross member in a vehicle front-rear direction and that are joined to the floor tunnel, and a first tunnel reinforcing member that is provided in a tunnel interior parallel to the cross member in the vehicle width direction.
Claims6
A tunnel reinforcing structure comprising:
- a floor tunnel that extends in a front-rear direction and that is opened toward a lower external side of a vehicle;
- an exhaust pipe that is arranged in an interior of the floor tunnel;
- a side sill that extends in the front-rear direction on an outer side in a vehicle width direction of the vehicle;
- a floor panel that is provided between the floor tunnel and the side sill;
- a floor cross member that extends on the floor panel in the vehicle width direction and that couples the floor tunnel and the side sill to each other;
- seat brackets that are arranged in front of and behind the floor cross member and that are joined to the floor tunnel;
- a first tunnel reinforcing member that is provided in the interior of the floor tunnel parallel to the floor cross member in the vehicle width direction;
- a floor frame that extends in the front-rear direction on the lower external side of the floor panel;
- and
- a coupling bracket that is arranged across the interior of the floor tunnel in the vehicle width direction and to which the exhaust pipe is coupled,
- wherein
- the seat brackets are attached to the floor frame via the floor panel, and are attached to the coupling bracket via the floor tunnel,
- the first tunnel reinforcing member includes
- an upper member that is arranged above an intermediate position of the floor tunnel in a height direction in the interior of the floor tunnel and that has a shape forming a closed cross section together with the floor tunnel, and
- a lower member that is arranged below the upper member and that has a shape tilted upward while extending from a lower portion of a side wall of the floor tunnel toward a center in the vehicle width direction,
- the lower member includes paired truss portions that have truss shapes obliquely coupling the upper member and side walls of the floor tunnel on both sides in the vehicle width direction to one another in the interior of the floor tunnel and a coupling portion that couples the paired truss portions to each other, and
- the coupling portion is arranged along a lower surface of the upper member.
