Chassis Structure Used for Storage Robot

Abstract

The invention discloses a chassis structure used for a storage robot, it includes a base plate, a driving wheel assembly and a driven wheel, the base plate includes a middle plate and two end plates,the end plate is hinged symmetrically on both sides of the middle plate by an axle hinge, and the middle plate is higher in height direction than the end plate; in a top view direction, the intermediate plate has a portion that overlaps the end plate over a hinge axis, and an adjustment spring is provided between the overlapping portion and the end plate. The chassis structure used for the storagerobot of this invention has the following advantages: (1) the chassis is a three-section structure, so that six wheels can fully land and fully ensure the stability of the vehicle body, and the requirement for the flatness of the ground is low; (2) the driving wheel is provided with a damping mechanism, so that the middle plate part of the chassis mainly carrying the weight is provided with a shock filtering function; and the walking accuracy of the storage robot can be ensured.

Description

technical field [0001] The invention relates to the field of robots, in particular to a chassis structure for a storage robot. Background technique [0002] With the explosive growth of e-commerce, the workload of e-commerce warehousing and sorting has also increased significantly. At present, many e-commerce warehouses are equipped to realize the automatic and unmanned handling of items in the warehouse, thereby reducing labor costs, shortening the delivery time of stored items, and improving the efficiency of storage and sorting. [0003] The warehouse robot is a squat novelty that looks like a fast-moving turtle. They shuttle through the warehouse, bringing entire racks of clothing, electronics, auto parts, whatever the retailer sells, to dedicated packing stations where workers select products, pack them and send them for shipping truck. [0004] The chassis of the storage robot has a 6-wheel structure, that is, two driving wheels in the middle, and two driven univers...

AI Technical Summary

Problems solved by technology

[0004] The chassis of the storage robot has a 6-wheel structure, that is, two driving wheels in the middle, and two driven universal casters at each end. The problem with the 6-wheel structure is that not all wheels can touch the ground at the same time, so that if the ground If the flatness is poor, some wheels will be lifted. If the driving wheel is lifted, it will affect the normal operation of the system. If the driven wheel is lifted, the load on the car body will be uneven, which will cause the car body to be unstable.
