Abstract

A beam assembly includes a first beam that has a first tubular portion and a first projecting portion that extends from the first tubular portion. A second beam has a second tubular portion and a second projecting portion that extends from the second tubular portion. The elongated interior of the first tubular portion defines a first hollow area and the elongated interior of the second tubular portion defines a second hollow area. The first beam is attached to the second beam with the first projecting portion attached to the second tubular portion and the second projecting portion attached to the first tubular portion to define a third hollow area between the first and second projecting portions.

First claim

What is claimed is:

1. A beam assembly comprising:
a first beam having a first tubular portion and a first projecting portion extending along the first tubular portion, wherein the first tubular portion surrounds a first hollow area;
a second beam having a second tubular portion and a second projecting portion extending along the second tubular portion, wherein the second tubular portion surrounds a second hollow area; and
wherein the first beam is attached to the second beam with the first projecting portion attached to the second tubular portion and the second projecting portion attached to the first tubular portion to define a third hollow area between the first and second projecting portions.

2. The beam assembly of claim 1 , wherein the first beam and the second beam each comprise a same cross-sectional shape.

3. The beam assembly of claim 1 wherein the first beam and the second beam each comprise a P-shaped cross-section taken transverse to a length of the first beam and the second beam.

4. The beam assembly of claim 3 , wherein the P-shaped cross-section extends continuously along the length of each of the first and second beams.

5. The beam assembly of claim 4 , wherein the first and second beams are attached together via welding.

6. The beam assembly of claim 1 , wherein the first tubular portion comprises a rectangular cross-sectional shape defined by four wall sections, and wherein the first projecting portion extends from the first tubular portion in planar alignment with one of the four wall sections.

7. The beam assembly of claim 6 , wherein the third hollow area is surrounded by the first and second projecting portions and by parallel wall sections of the first and second tubular portions.

8. The beam assembly of claim 1 , wherein the first and second projecting portions each include a channel rib extending along a length of the respective first and second beam, and wherein the channel ribs are disposed at opposing sides of the third hollow area.

9. The beam assembly of claim 1 , further comprising:
a third beam having a third tubular portion and a third projecting portion extending along the third tubular portion, wherein the first, second, and third beams each comprise a same cross-sectional shape, and wherein the third beam is attached to the second beam with the third projecting portion perpendicular to the first and second projecting portions to form a floor support for a vehicle battery tray.

10. The beam assembly of claim 1 , wherein a wall of the first tubular portion comprises a planar section and a recessed section that is configured to engage the second projecting portion, and wherein the planar section of wall of the first tubular portion is disposed in alignment with the second projecting portion and together form an outer wall of the beam assembly.

11. The beam assembly of claim 1 , wherein the first and second projecting portions extend outward from attachment at the respective first or second tubular portion to define a flange, and wherein the beam assembly comprises at least a component of a rocker section.

12. A beam assembly comprising:
a first beam comprising a first tubular portion and a first projecting portion extending along the first tubular portion;
a second beam comprising a second tubular portion and a second projecting portion extending along the second tubular portion;
wherein the first and second beams are formed from a metal sheet, the first and second tubular portions each having a seam disposed along a length thereof that is defined by an edge section of the metal sheet attached along an intermediate section of the metal sheet, and the first and second projecting portions integrally protruding at the seam from the intermediate section of the metal sheet; and
wherein the first beam is attached to the second beam with the first projecting portion attached to the second tubular portion and the second projecting portion attached to the first tubular portion to define a hollow area between the first and second projecting portions.

13. The beam assembly of claim 12 , wherein a cross-sectional shape of the first beam taken transverse to the length is the same as a cross-sectional shape of the second beam taken transverse to the length.

14. The beam assembly of claim 13 , wherein the cross-sectional shape of each of the first and second beams is P-shaped.

15. The beam assembly of claim 12 , wherein the first and second beams are attached together via welding.

16. The beam assembly of claim 12 , wherein the first tubular portion comprises a rectangular cross-sectional shape defined by four wall sections, and wherein the first projecting portion extends from the first tubular portion in planar alignment with one of the four wall sections.

17. The beam assembly of claim 12 , wherein the first and second beams each include a channel rib disposed along the length thereof.

18. The beam assembly of claim 12 , wherein the first and second projecting portions extend outward from attachment at the respective first or second tubular portion to define a flange.

19. The beam assembly of claim 12 , wherein a wall section of the first tubular portion comprises a recessed area that engages the second projecting portion.

20. The beam assembly of claim 12 , wherein the beam assembly comprises one of a roof bow, a header, a pillar, a rocker, a cross members, a bumper beam, a door beams, a frame rail tip, or a battery tray wall.
