AI Technical Summary
Technical Problem
In order to protect the battery, existing battery trays need to ensure crushing rigidity caused by external forces, which sometimes have too much weight.
Method used
A pallet is designed with a high-strength portion with high tensile strength and a low-strength portion with low tensile strength. The low-strength portion contains a recess and is formed by stamping. The high-strength portion is responsible for bearing impact loads. The low-strength portion is used for simple forming during the manufacturing process.
Benefits of technology
It is achieved to provide a strong and lightweight pallet, improve the rigidity of the pallet through a high-strength part, and simplify the manufacturing process through a low-strength part, achieving the goal of lightweighting.

Abstract
A tray (20) includes a bottom wall (21) and a peripheral side wall (22) vertically arranged from the outer periphery of the bottom wall (21), and includes a high-strength portion HT having a high tensile strength and a low-strength portion LT having a lower tensile strength than the high-strength portion HT. The low-strength portion LT is formed by including a recess (C), the recess (C) including a corner portion (22C) in a first side wall inner surface (221a) and a second side wall inner surface (222a) adjacent to each other at a minor angle, and a corner portion (21C) in an upper surface (21a) of the bottom wall (21) at a minor angle to the first side wall inner surface (221a) and the second side wall inner surface (222a).
