[0002] An AGV is a transport vehicle equipped with an automatic guidance device such as an electromagnetic or optical device, capable of traveling along a specified guidance path, with safety protection and various transfer functions. It is a transport vehicle that does not require a driver in industrial applications and uses a rechargeable battery as its power source.

[0003] The existing Chinese patent CN208915290U disclosed an AGV transport trolley on May 31, 2019, including a cargo rack and an AGV trolley arranged at the lower end surface of the cargo rack. The lower end surface of the cargo rack is provided with a plurality of universal wheels, and the plurality of universal wheels surround the AGV trolley. When the AGV trolley is traveling on the road, the traction wheel of the AGV trolley and the outer wall of the universal wheel jointly contact the road surface. In the above patent, by setting a universal wheel under the cargo rack, when the AGV trolley is traveling on the road surface, the traction wheel of the AGV trolley and the universal wheel jointly contact the road surface, so that the universal wheel shares the load of the AGV trolley, and then disperses the weight carried, achieving the effect of reducing the load strength of the AGV trolley. However, in actual use, the AGV trolley is likely to hit the shelves in the warehouse area, causing the goods on the AGV trolley to fall over, and in serious cases, the trolley itself will be damaged. Therefore, further improvement is needed. Utility Model Content
