Description

Technical Field

[0001] This utility model relates to the field of transport vehicle technology, specifically a positioning and adjustment device for a transport vehicle. Background Technology

[0002] A transport vehicle is an automated device used for transporting goods or materials, widely used in factories, warehouses, logistics centers, and other similar settings. It is typically equipped with a drive system, navigation device, and control system, enabling it to travel autonomously or semi-autonomously along a predetermined path. Depending on the requirements, transport vehicles can be divided into two types: tracked and trackless. Tracked vehicles run along fixed tracks, while trackless vehicles achieve flexible movement through laser, vision, or magnetic strip navigation. In existing transport vehicles, objects are placed directly on the vehicle; however, the lack of a positioning and adjustment structure prevents the vehicle from accurately positioning objects according to their size, leading to objects easily falling off during transport. Therefore, based on actual usage experience, we have improved upon the aforementioned existing technology. Utility Model Content
