Vehicle floor structure
A vehicle floor structure includes a floor member that includes an opening that is open at an end corresponding to an entrance, the opening extending toward a vehicle cabin side, and a floor panel that is supported by the floor member to cover the opening and includes an open end at a position corresponding to the entrance. The floor panel is configured by sequentially arranging and integrating unit panels in a width direction with a direction parallel to the open end serving as a longitudinal direction of the unit panels.
1. A vehicle floor structure comprising:
a floor member that includes an opening that is open at an end corresponding to an entrance, the opening extending toward a vehicle cabin side;
a ramp disposed in the opening; and
a floor panel disposed above the ramp that is separate and removable from the floor member and that is supported by the floor member to cover the opening and includes an open end at a position corresponding to the entrance, wherein the floor panel is configured by sequentially arranging and integrating unit panels in a width direction with a direction parallel to the open end serving as a longitudinal direction of the unit panels.
2. The vehicle floor structure according to claim 1 , wherein:
an insertion hook that faces downward is provided on one side of a unit panel in the width direction and an open hook receiving port that faces upward is provided on another side of the unit panel in the width direction; and
the insertion hook on another unit panel is inserted into and engaged with the hook receiving port of one unit panel on the open end side to integrate two adjacent unit panels.
3. The vehicle floor structure according to claim 1 , wherein:
two open insertion hooks that face downward are provided on one side of a unit panel in the width direction and two open hook receiving ports that face upward are provided on another side of the unit panel in the width direction; and
the two insertion hooks on another unit panel are inserted into and engaged with the two hook receiving ports of one unit panel on the open end side to integrate two adjacent unit panels.
4. The vehicle floor structure according to claim 1 , wherein the unit panel has a hollow plate shape that has a closed cross section, and includes a rib extending in the longitudinal direction inside the unit panel and connecting a front surface and a back surface of the unit panel in the closed cross section.
5. The vehicle floor structure according to claim 1 , wherein the unit panel is made of aluminum.
6. The vehicle floor structure according to claim 1 , wherein the unit panel has a quadrangular closed cross section, and includes a front surface, a back surface, a first side surface, a second side surface, and a plurality of longitudinally extending ribs disposed between the first and second side surface and connecting the front surface and the back surface, the plurality of longitudinally extending ribs defining a plurality of chambers within the unit panel, wherein a chamber disposed adjacent the first side surface and a chamber disposed adjacent the second side surface have a width and a height smaller than a width and a height of a remaining plurality of chambers.
7. The vehicle floor structure according to claim 1 , wherein at least one unit panel adjacent the open end of the floor panel includes a front surface that is at least partially inclined toward the vehicle cabin side.
