AGV chassis

Abstract

The invention 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, and the front frame and the driving wheel assemblies form a first lever structure through the first side arm. The rear frame and the driving wheel assembly form a second lever structure through a 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 enables the midpoint of the connecting line between the driving wheels of the two driving wheel assemblies to coincide with the center of the bottom plate through the adjusting mechanism. Compared with the prior art, the AGV chassis has the advantages that the midpoint of the connecting line between the driving wheels of the two driving wheel assemblies coincides with the center of the bottom plate through the adjusting mechanism, it is guaranteed that the rotating center of the vehicle body cannot be changedalong with fluctuation or inclination of the road surface, accordingly, the control precision of the vehicle body is improved, and position errors caused by excessive deviation of an AGV are effectively prevented.

Description

technical field [0001] The invention relates to the technical field of AGV chassis, and mainly relates to an AGV chassis. Background technique [0002] Backpack AGV refers to the AGV vehicle that relies on the AGV body to carry the weight of the cargo. This type of AGV vehicle is mostly used in assembly, logistics and other fields. The chassis structure of the existing AGV car, especially the small AGV car, generally realizes the adaptive ground deformation of the AGV car through two frame hinges. However, when the existing chassis structure encounters undulating roads, the two driving The center of the wheel connection (that is, the control center point of the car body algorithm) and the center of the bottom plate) will be inconsistent, resulting in that when the car body rotates, the calculation of the car body motion in the algorithm is inconsistent with the actual operation. One direction is offset, and the running accuracy is poor. If the error is large, the AGV will d...

The chassis structure of the existing AGV car, especially the small AGV car, generally realizes the adaptive ground deformation of the AGV car through two frame hinges. However, when the existing chassis structure encounters undulating roads, the two driving The center of the wheel connection (that is, the control center point of the car body algorithm) and the center of the bottom plate) will be inconsistent, resulting in that when the car body rotates, the calculation of the car body motion in the algorithm is inconsistent with the actual operation. One direction is offset, and the running accuracy is poor. If the error is large, the AGV will directly lose the coordinates and then report an error. This problem will also occur when the AGV needs to lift the goods. After the rotation, the position of the body and the goods will shift, which will affect AGV running accuracy
