Automated guided vehicle (AGV) base structure and AGV

Abstract

The invention relates to an automated guided vehicle (AGV) base structure and an AGV. The AGV base structure comprises a bottom plate and two floating devices. The two floating devices are fixed to opposite two sides of the bottom plate. Each floating device comprises a lever arm, a driving device, an omnidirectional wheel and a hinged supporting assembly. One ends of the lever arms are fixed to the driving devices, and the omnidirectional wheels are fixed to the other ends of the lever arms. The middle parts of the lever arms are fixed to the bottom plate by the hinged supporting assemblies in a floatable mode. The two driving devices can guarantee high driving power. Each hinged supporting assembly enables the lever arms to conveniently float up and down with fluctuation of the ground when the omnidirectional wheels run on the ground, and therefore the two floating devices have better floating performance and stability. Compared with thesituationthat a traditional spring drives a driving device to float up and down, the lever arms have longer service life, and the cost of an AGV base is saved.

Description

technical field [0001] The invention relates to the technical field of automatic guided transport vehicles, in particular to an AGV base structure and an AGV vehicle. Background technique [0002] AGV (Automated Guided Vehicle) refers to an automatic guided vehicle equipped with a driving device as a power device. The driving device is installed on the chassis of the automatic guided vehicle, and the automatic guided vehicle can drive along a specified path. With safety protection and transfer functions, it is widely used in the chassis structure of six-wheel AGV. [0003] In related technologies, in order to enable the AGV to run stably on the undulating ground, the AGV chassis structure is equipped with a floating drive device. The floating drive device usually adopts a single-point support structure. Although compared with the six-wheel AGV chassis structure, the single-point support The structure has the advantages of simple structure and low cost, but one end of the si...

Problems solved by technology

[0003] In related technologies, in order to enable the AGV to run stably on the undulating ground, the AGV chassis structure is equipped with a floating drive device. The floating drive device usually adopts a single-point support structure. Although compared with the six-wheel AGV chassis structure, the single-point support The structure has the advantages of simple structure and low cost, but one end of the single-point support structure is a hinged end and the other end is a floating end with a spring installed. When the AGV is running on the ground, the spring is compressed to realize the floating end of the driving device. The end floats up and down. If the spring strength is large, the sensitivity of the drive device to float up and down is poor. If the spring strength is small, the spring will bend, which will easily reduce the stability and service life of the AGV chassis structure.
