AI Technical Summary

Technical Problem

When the existing AGV chassis rotates on undulating roads, the center of the drive wheel connection line is not aligned with the center of the base plate, causing the vehicle body to deviate during rotation, which affects the running accuracy and positional accuracy.

Method used

The structure includes a base plate, front frame, rear frame, drive wheel assembly, adjustment mechanism, first side arm and second side arm. The adjustment mechanism makes the midpoint of the line connecting the drive wheel assembly coincide with the center of the base plate. The degree of freedom limiting structure and waist-shaped hole are used for limiting to ensure the stability of the vehicle body rotation center.

Benefits of technology

It improves the control precision of AGV vehicles, prevents deviation, achieves precise operation, and enhances the stability and positional accuracy of the vehicle body on undulating roads.

Abstract

The application provides an AGV chassis, which comprises a bottom plate, a front frame, a rear frame, two driving wheel assemblies, an adjusting mechanism, a first side arm and a second side arm, the first side arm and the second side arm are rotatably arranged on the bottom plate, the front frame forms a first lever structure with the driving wheel assembly through the first side arm, the rear frame forms a second lever structure with the driving wheel assembly through the second side arm, and the adjusting mechanism is arranged between the bottom plate and the driving wheel assembly; when the first lever structure and the second lever structure swing, the driving wheel assembly makes the midpoint of the line between the driving wheels of the two driving wheel assemblies coincide with the center of the bottom plate through the adjusting mechanism. Compared with the prior art, the AGV chassis provided by the application makes the midpoint of the line between the driving wheels of the two driving wheel assemblies coincide with the center of the bottom plate through the adjusting mechanism, so that the rotation center of the vehicle body cannot change with the ups and downs or inclination of the road surface, thereby improving the control accuracy of the vehicle body and effectively preventing the AGV from deviating too much and causing position error.
