AI Technical Summary

Technical Problem

Electric forklift chassis are susceptible to impacts during operation, causing the battery pack to be directly subjected to severe impacts, resulting in deformation, misalignment and damage of internal cells, increased maintenance costs and safety hazards.

Method used

A collision protection component, including a collision plate and a buffer plate, is installed on the bottom surface of the chassis body. The impact energy is absorbed by the elastic deformation of the buffer plate to prevent the impact force from acting directly on the battery pack. Combined with the push cylinder to adjust the center of gravity of the battery pack to improve stability.

Benefits of technology

It effectively prevents battery casing deformation and internal cell misalignment and damage, extends battery pack life, reduces safety risks, and improves the reliability of electric forklifts in complex scenarios.

Abstract

This invention belongs to the field of new energy vehicle technology, specifically relating to a battery pack protection device for an electric forklift chassis, and more particularly to an electric forklift chassis and its working method. The electric forklift chassis includes: a chassis body with a battery pack placement slot; and a collision protection component. The collision protection component includes: a collision plate and a buffer plate. When the collision plate is impacted by an external force, the buffer plate absorbs the impact force, reducing the impact on the battery pack placement slot and thus reducing the impact on the battery pack. By installing the collision protection component on the bottom surface of the chassis body, when the bottom surface of the chassis is impacted, the collision plate first absorbs the external force, and the buffer plate absorbs the impact energy through elastic deformation, preventing the impact force from directly acting on the battery pack placement slot and the battery pack itself. This effectively prevents deformation of the battery casing, misalignment and damage of internal cells, and extends the battery pack's lifespan.
