Abstract

A fuel-storage tank for a vehicle includes a body defining an interior volume having a floor and a ceiling and configured to store fuel. The tank further includes an anti-slosh reinforcement column extending between the floor and the ceiling. The anti-slosh reinforcement column has a vertical baffle extending between the floor and the ceiling. The vertical baffle has opposing first and second major faces and edges extending therebetween. A horizontal baffle of the column has upper and lower major faces and edges extending therebetween. The horizontal baffle is rigidly supported on the vertical baffle such that the first and second major faces are substantially perpendicular to the upper and lower major faces.

First claim

What is claimed is:

1. A fuel-storage tank for a vehicle comprising:
a body defining an interior volume configured to store fuel; and
a plurality of anti-slosh reinforcement columns extending between a floor and a ceiling of the interior, at least one of the columns including:
upper and lower mounts attached to the ceiling and floor, respectively,
a planar vertical baffle extending from the lower mount to the upper mount and having opposing first and second major faces, and
a planar horizontal baffle rigidly supported on the vertical baffle to suspend the horizontal baffle between the upper and lower mounts, wherein the horizontal baffle has a first portion extending from the first face and a second portion extending from the second face, and
a fin extending from the first major face, wherein the fin includes an inner edge connected to the one of the major faces and an outer edge, and wherein a distance between the inner and outer edges varies along a length of the fin.

2. The fuel-storage tank of claim 1 , wherein the horizontal baffle has a peripheral edge with a plurality of notches.

3. The fuel-storage tank of claim 1 , wherein the vertical baffle defines a plurality of apertures extending through the first and second major faces.

4. The fuel-storage tank of claim 1 , wherein the at least one column further includes a fin extending from the first major face.

5. The fuel-storage tank of claim 4 , wherein the horizontal baffle is perpendicular to a longitudinal direction of the fin.

6. The fuel-storage tank of claim 5 , wherein the fin extends through the horizontal baffle plate.

7. The fuel-storage tank of claim 4 , wherein the fin extends from the upper mount to the lower mount.

8. The fuel-storage tank of claim 1 , wherein the distance is larger at ends of the fin than at a midpoint of the fin.

9. The fuel-storage tank of claim 1 , wherein the fin is a first set of fins that are arranged across a width of the first face with spacing therebetween and the at least one column further includes:
a set of second fins extending vertically from the upper mount to the lower mount to bisect the horizontal baffle plate, each of the second fins having an inner edge connected to the second major face and extending substantially perpendicular therefrom to a free outer edge, wherein the second fins are arranged across a width of the second face with spacing therebetween.

10. The fuel-storage tank of claim 9 , wherein the first fins are aligned with corresponding ones of the second fins.

11. The fuel-storage tank of claim 1 , wherein the horizontal baffle is a pair of baffles that are vertically spaced from each other.

12. A fuel-storage tank for a vehicle comprising:
a body defining an interior volume having a floor and a ceiling and configured to store fuel; and
an anti-slosh reinforcement column extending between the floor and the ceiling, the anti-slosh reinforcement column including:
a vertical baffle extending between the floor and the ceiling and having opposing first and second major faces and edges extending therebetween,
a horizontal baffle having upper and lower major faces and edges extending therebetween, the horizontal baffle being rigidly supported on the vertical baffle such that the first and second major faces are substantially perpendicular to the upper and lower major faces, wherein the horizontal baffle includes an inner edge connected to the first major face, and
a second horizontal baffle having an inner edge connected to the second major face, wherein the horizontal baffle and the second horizontal baffle are vertically offset relative to each other, wherein the horizontal baffle is wider than the second horizontal baffle.

13. The fuel-storage tank of claim 12 , wherein the column further includes a fin extending between the floor and the ceiling such that the fin is substantially perpendicular to the horizontal and vertical baffles.

14. The fuel-storage tank of claim 13 , wherein the fin includes an inner edge connected to the first major face and extends therefrom to an outer edge, and wherein a distance between the inner and outer edges varies along a length of the fin.

15. The fuel-storage tank of claim 12 , wherein the horizontal baffle includes an inner edge connected to the first major face, and further including a second horizontal baffle having an inner edge connected to the second major face, wherein the horizontal baffle and the second horizontal baffle are vertically offset relative to each other.

16. The fuel-storage tank of claim 12 , wherein one of the edges of the horizontal baffle defines a plurality of notches.

17. A fuel-storage tank for a vehicle comprising:
a body having a floor, a ceiling, and at least one sidewall defining an interior volume configured to store fuel;
a first reinforcement column extending from the floor to the ceiling, the first reinforcement column including a planar vertical baffle and a planar horizontal baffle being rigidly supported on the vertical baffle; and
a second reinforcement column extending from the floor to the ceiling, the second reinforcement column including a planar vertical baffle and a pair of planar horizontal baffles being vertically spaced from each other, the pair of horizontal baffles being rigidly supported on the vertical baffle of the second column, wherein the second reinforcement column has more horizontal baffles than the first reinforcement column.

18. The fuel-storage tank of claim 17 , wherein the first reinforcement column further includes a vertically extending fin that is substantially perpendicular to the horizontal and vertical baffles, and wherein the second reinforcement column further includes a vertically extending fin that is substantially perpendicular to the pair of horizontal baffles and the vertical baffle.

19. The fuel-storage tank of claim 17 , wherein the vertical baffle of the first reinforcement column defines a hole extending through a thickness of the thereof.

20. The fuel-storage tank of claim 17 , wherein the a first reinforcement column further includes a fin having an inner edge connected to the vertical baffle of the first column and an outer edge, and wherein a distance between the inner and outer edges varies along a length of the fin.
