An 1-piece molded explosion-proof aluminum battery casing

Abstract

This utility model discloses an integrally molded explosion-proof battery aluminum shell, including an aluminum shell, which includes a shell cylinder and a shell end fixed to the end of the shell cylinder. The surface of the shell end is distributed with electrode welding parts and pressure relief grooves. Through the design of the pressure relief grooves, when an explosion occurs inside the aluminum shell, the instantaneous high pressure generated will break through the pressure relief grooves. At this time, the pressure will be released from the broken pressure relief grooves, allowing the airflow to carry debris out in a fixed direction, reducing the intensity and degree of harm of the explosion. The design of the reinforced protrusions can strengthen the shell end and prevent the shell end from breaking under high pressure, which is not conducive to the design of pressure being released only from the broken pressure relief grooves. At the same time, through the design of the protective components, on the one hand, it can concentrate and restrain the high-speed airflow debris to prevent it from scattering and splashing, and on the other hand, it can intercept and buffer larger debris to prevent large debris from rushing out at high speed and causing damage to the outside.
