Abstract: A multi-functional cargo transfer vehicle and method. The multi-functional cargo transfer vehicle comprises a vehicle body, a cargo conveying rack, a lifting mechanism, and a control system; the vehicle body is located below for providing a platform and support; the cargo conveying rack is located above the vehicle body and includes a plurality of layers for loading and unloading cargoes; the lifting mechanism is located on the outer side of the cargo conveying rack for lifting the cargo conveying rack; the control system is located on the vehicle body for controlling omni-directional driving, accurate butt joint, and automatic loading and unloading of the multi-functional cargo transfer vehicle. Accordingly, a multi-functional cargo transfer vehicle is adopted such that the multi-task functions of loading and unloading, transporting, and conveying of cargoes are simultaneously realized, thereby efficiently completing the transferring process of cargoes from a storage place to a transporting carrier.
