Description

Technical Field

[0001] This invention relates to the technical field of transport vehicle parts, specifically to an automatic tilting fence, system, and method for an unmanned transport vehicle. Background Technology

[0002] Currently used transport vehicles, when transporting small, loose packages, require side guardrails to prevent materials from accidentally falling during transport. However, when using forklifts for loading and unloading, these guardrails must be fully opened to facilitate access and operation by the forklifts. In practice, manual operation is often the primary method; however, this manual intervention prevents a fully automated operating environment.

[0003] On the other hand, in the transportation of some goods, in order to maximize the versatility of transportation, the size of the goods or materials may exceed the size of the vehicle. In actual use, if the goods or materials exceed the vehicle's size but the load capacity is within limits, the vehicle must stop loading, thus limiting the carrying capacity of the transport vehicle. Simultaneously, due to environmental constraints, the vehicle's passage space is limited, thus some road environments impose requirements on the vehicle's width. If a transport vehicle with a larger carrying area is used, it may be unusable in some environments, increasing the variety of vehicles and hindering cost reduction and vehicle management. Therefore, this invention proposes an automatic tilting fence system and method for unmanned transport vehicles to solve the above problems. Summary of the Invention
