AI Technical Summary

Technical Problem

The existing battery support structure in power-operated work machines, such as electric excavators, is prone to tilting, which can lead to interference with surrounding components, inefficient space utilization, and increased eccentric loads on the elastic mounts, affecting operability.

Method used

A battery frame supported by first and second damping members, with brackets positioned on opposite surfaces and at different heights, and connected via damper mounts to stabilize the battery frame and suppress tilting.

Benefits of technology

The solution effectively suppresses battery tilting, enhances space utilization efficiency, and stabilizes the battery frame, reducing interference with surrounding components and improving operator sensory experience.
