Description

Technical Field

[0001] This utility model belongs to the field of AGV (Automated Guided Vehicle) technology, specifically relating to an external parking structure for an AGV. Background Technology

[0002] AGVs are intelligent vehicles that can be automatically guided. Cargo transport is the basic function of AGVs. AGVs can automatically transfer goods according to preset routes. Some existing AGVs also have the function of self-unloading, realizing fully automated loading and unloading of goods. However, for some heavy or large goods, the AGV is prone to tilting or overturning due to the change in the center of gravity during loading and unloading, which may even cause loading and unloading accidents. Therefore, it is necessary to improve the stability of the AGV chassis through external parking devices to cope with the change in the center of gravity of the chassis during loading and unloading.
