1. A vehicle battery tray structure comprising:
- a bracket interconnecting a battery enclosure and a floor, having first and second parallel flanges interconnected by a side; and
a plate disposed at an angle between the flanges, and configured to rupture at a trigger during an impact such that, coupled with deformation of the first flange, the enclosure shifts in a direction away from the impact while the second flange maintains attachment to the floor, wherein the plate includes first and second ends attached to the first and second parallel flanges, respectively, such that a wall interconnects the ends and includes the trigger.

Abstract
A vehicle underbody includes a battery pack surrounded by an enclosure, and a bracket. The bracket has first and second flanges disposed in a parallel arrangement, and includes a plate having a wall configured to, in response to an impact, rupture at a trigger to allow the enclosure to move away from an impact direction and deform the first flange. The wall is disposed at angle relative to the flanges, and defined such that impact energy is absorbed by the wall and first flange. The first flange, during an impact, moves toward the second flange, which maintains attachment to the vehicle underbody to absorb energy.
