AI Technical Summary

Technical Problem

The existing tolerance adjustment device has complex structure, difficult assembly, high manufacturing cost, inconvenient operation and affects the battery pack installation efficiency, and is prone to crush the battery pack lifting lugs during the adjustment process.

Method used

A heavy-load anti-loose pin limit tolerance regulator is designed, including a cylinder, an adjustment screw and an elastic limit spring. By adjusting the anti-slip marks of the adjustment screw and the annular limit plate contact with the bottom surface of the frame, the tolerance adjustment of the distance between the battery pack lifting lugs and the frame is realized, and the deformation of the lifting lugs caused by excessive torque is prevented through arc-shaped shrapnel and limit pins.

Benefits of technology

The convenience and efficiency of tolerance adjustment are achieved, manufacturing costs and assembly difficulties are reduced, the risk of crushing the battery pack lugs during the adjustment process is avoided, and the installation efficiency of the battery pack is improved.
