Abstract

An assembly includes a subframe, a rocker, a battery cage supported by the rocker, and a battery supported by the battery cage. The assembly includes a reinforcement bolted to the rocker and positioned to be along a load path through the subframe resulting from a vehicle frontal impact.

First claim

What is claimed is:

1. An assembly comprising:
a subframe;
a rocker;
a battery cage supported by the rocker;
a battery supported by the battery cage; and
a reinforcement bolted to the rocker and positioned to be along a load path through the subframe resulting from a vehicle frontal impact.

2. The assembly of claim 1 , further comprising bolts connecting the reinforcement to the rocker, the bolts being designed to be breakable relative to at least one of the reinforcement and the rocker.

3. The assembly of claim 2 , wherein the reinforcement separates from the rocker when the bolts break relative to at least one of the reinforcement and the rocker.

4. The assembly of claim 1 , further comprising bolts connecting the reinforcement to the rocker at connection points, wherein at least one of the bolts, the reinforcement at the connection points, and the rocker at the connection points is designed to allow the reinforcement to separate from the rocker during the vehicle frontal impact.

5. The assembly of claim 1 , wherein the subframe is fixed to the rocker throughout the vehicle frontal impact.

6. The assembly of claim 2 , wherein the reinforcement is elongated along a longitudinal axis, and the bolts are spaced along the longitudinal axis.

7. The assembly of claim 1 , wherein the reinforcement has a cross-section that is rectangular.

8. The assembly of claim 7 , wherein the cross-section of the reinforcement is hollow.

9. The assembly of claim 1 , wherein the reinforcement has a cross-section that is hollow.

10. The assembly of claim 1 , further comprising a bridging bracket extending from the subframe to the reinforcement.

11. The assembly of claim 1 , wherein the rocker includes a topside and an underside opposite the topside, and the reinforcement is bolted to the underside of the rocker.

12. The assembly of claim 1 , wherein the reinforcement is spaced from the battery cage.

13. The assembly of claim 1 , wherein the rocker is between the reinforcement and the battery cage.

14. The assembly of claim 1 , further comprising a second rocker opposite the rocker, and the battery cage extends from the rocker to the second rocker.

15. The assembly of claim 1 , further comprising a second rocker, the second rocker being spaced from the rocker, and the battery cage being between the second rocker and the rocker.
