Abstract

A vehicle lower section structure includes a battery unit that is disposed below a floor panel, a sliding door that is provided to a side section of a vehicle body, and a lower hinge that is attached to a lower portion of the sliding door, that supports the sliding door with respect to the vehicle body such that the sliding door is capable of sliding in a vehicle front-rear direction, and that is disposed further toward a vehicle upper side than the battery unit.

First claim

What is claimed is:

1. A vehicle lower section structure comprising:
a battery unit disposed at a vehicle lower side of a floor panel;
a sliding door provided at a side section of a vehicle body; and
a lower hinge that is disposed further toward a vehicle upper side than the battery unit, that is attached to a lower portion of the sliding door, and that supports the sliding door with respect to the vehicle body so as to be slidable in a vehicle front-rear direction,
wherein the battery unit is disposed so as to overlap with the lower hinge as viewed from above the vehicle.

2. The vehicle lower section structure of claim 1 , wherein:
the vehicle body is provided with a step used when entering or leaving the vehicle; and
a lower guide to guide the lower hinge is integrally formed at the step such that the lower hinge is movable in the vehicle front-rear direction.

3. The vehicle lower section structure of claim 2 , wherein:
an opening/closing device of the sliding door is attached to the step; and
the opening/closing device is disposed further toward the vehicle upper side than the battery unit.

4. The vehicle lower section structure of claim 1 , further comprising a side member that is disposed at a lower face side of the floor panel so as to configure a closed cross-section with the floor panel and so as to be disposed further toward the vehicle upper side than the battery unit.

5. The vehicle lower section structure of claim 1 , wherein a shock absorbing member is disposed further toward a vehicle width direction outer side than the battery unit.

6. The vehicle lower section structure of claim 5 , wherein:
a rocker extends along the vehicle front-rear direction at a lower section of the vehicle body; and
the shock absorbing member is disposed within a cross-section of the rocker.

7. The vehicle lower section structure of claim 5 , wherein:
a peripheral wall is provided at a side portion of the battery unit, the peripheral wall being partitioned into a plurality of closed cross-sections arranged along a vehicle vertical direction by an up-down partitioning wall extending in the vehicle width direction; and
the shock absorbing member is disposed at the vehicle width direction outer side of the peripheral wall, and is partitioned into a plurality of closed cross-sections arranged along the vehicle width direction by a left-right partitioning wall extending in the vehicle vertical direction.

8. A vehicle lower section structure comprising:
a battery unit disposed at a vehicle lower side of a floor panel;
a sliding door provided at a side section of a vehicle body; and
a lower hinge that is disposed further toward a vehicle upper side than the battery unit, that is attached to a lower portion of the sliding door, and that supports the sliding door with respect to the vehicle body so as to be slidable in a vehicle front-rear direction, wherein:
the vehicle body is provided with a step used when entering or leaving the vehicle;
a lower guide to guide the lower hinge is integrally formed at the step such that the lower hinge is movable in the vehicle front-rear direction;
an opening/closing device of the sliding door is attached to the step; and
the opening/closing device is disposed further toward the vehicle upper side than the battery unit.

9. The vehicle lower section structure of claim 8 , further comprising a side member that is disposed at a lower face side of the floor panel so as to configure a closed cross-section with the floor panel and so as to be disposed further toward the vehicle upper side than the battery unit.

10. The vehicle lower section structure of claim 8 , wherein a shock absorbing member is disposed further toward a vehicle width direction outer side than the battery unit.

11. The vehicle lower section structure of claim 10 , wherein:
a rocker extends along the vehicle front-rear direction at a lower section of the vehicle body; and
the shock absorbing member is disposed within a cross-section of the rocker.

12. The vehicle lower section structure of claim 10 , wherein:
a peripheral wall is provided at a side portion of the battery unit, the peripheral wall being partitioned into a plurality of closed cross-sections arranged along a vehicle vertical direction by an up-down partitioning wall extending in the vehicle width direction; and
the shock absorbing member is disposed at the vehicle width direction outer side of the peripheral wall, and is partitioned into a plurality of closed cross-sections arranged along the vehicle width direction by a left-right partitioning wall extending in the vehicle vertical direction.
