The patent application (Publication Number: US20240030537A1) describes a battery box for a vehicle that includes a unique design to securely hold one or more batteries. The battery box comprises longitudinal and lateral walls made of dual-phase steel, with corner junctions serving as load-bearing connections. The box features corner shields made of draw steel, externally mounted to provide fluid-tight sealing over the corner junctions. These shields have complex corners formed by planar wall segments extending in multiple planes, ensuring a secure and sealed enclosure for the batteries.

Furthermore, the design includes wedge-shaped channels formed by planar wall segments in the corner shields, providing additional structural integrity and sealing. The corner shields are positioned underneath flanges on the walls, with a drop-in floor and lid secured in overlapping arrangements to enhance the box's overall strength and sealing capabilities. The use of spot welds on the corner junctions, along with adhesive or sealant for mounting the shields, ensures a permanent and fluid-tight connection. Overall, the battery box design offers a robust and secure solution for housing batteries in vehicles, with a focus on structural strength, sealing, and ease of assembly.
