Chassis structure for AGV (Automated Guided Vehicle)

Abstract

The invention relates to a chassis structure for an AGV (Automated Guided Vehicle). The chassis structure comprises a quadrangular chassis rack, wherein four corners of the chassis rack are respectively provided with a Mecanum wheel component; four corners of the chassis rack are respectively provided with a suspension mechanism; each suspension mechanism comprises an installation seat, a swingingplate, a swinging pin, a spring and a stop plate, each installation seat is fixedly connected to one corner of the chassis rack, the swinging plates are rotatably connected to the installation seatsthrough the swinging pins, certain ends of the springs are connected with the installation seats, the other ends are connected with the swinging plates, and certain ends of the stop plates are fixedlyconnected to the installation seats; when the swinging plates carries out over-weight bearing, the upper parts of the swinging plates are abutted against the stop plates; the Mecanum wheel componentsare installed on the swinging plates. Each Mecanum wheel component is provided with one independent suspension mechanism, each Mecanum wheel can touch the ground, uneven pavements can be coped with,and in addition, the AGV vehicle can stably and accurately run.

Description

technical field [0001] The invention relates to a chassis structure of an AGV vehicle. Background technique [0002] AGV is the abbreviation of (Automated Guided Vehicle), which means "automatic guided vehicle". AGV installs four mecanum wheel assemblies on the chassis frame. The mecanum wheel comes from the Swedish mecanum company. The azimuth mobile wheel set is that a plurality of roller assemblies are distributed obliquely on its rim, so the wheels can slide laterally. The bus bar of the roller assembly is very special. When the wheel rotates around the main shaft, the envelope of each roller assembly is a cylindrical surface, so the wheel can roll forward continuously. The mecanum wheel is compact in structure and flexible in movement, and is a very successful all-round wheel. There are four transport vehicles combined with these new wheels, which can realize all-round mobile functions more flexibly and conveniently. [0003] The traditional AGV chassis structure dir...

AI Technical Summary

Problems solved by technology

[0003] The traditional AGV chassis structure directly installs the mecanum wheel assembly. If the installation is not in place, or the installation is not at the same level, three of the wheels will touch the ground, and the other wheel will not be able to touch the ground, or the chassis frame will be misaligned. If it is inclined, it will affect the running accuracy of the AGV, and it will not be able to cope with the undulating road surface.
