The driving motor drives the lifting synchronous belt through the driving assembly to drive the car assembly to lift and lower, and the two ends of the lifting synchronous belt are directly connected and fixed to the top and bottom of the car assembly. This lifting mechanism effectively reduces the redundancy of load-bearing performance, greatly improves space efficiency, and greatly improves the convenience of disassembly and assembly by placing the driving motor at the bottom and directly connecting the lifting synchronous belt; the structure is highly streamlined, and the operation is stable and reliable, and it is especially suitable for use in logistics warehouses for small and medium-sized objects.

[0013] (1) The belt transmission mechanism is driven by the reduction motor through the rotating shaft and the gear box in turn, so that the belt transmission mechanism drives the active roller to rotate, so that the active roller cooperates with the driven roller to drive the lifting belt to operate. Because the outer wall of the lifting belt is provided with bearing plates at equal intervals, the logistics box only needs to be placed on the top of the bearing plates on the outer wall of the two lifting belts to continuously lift and transport the logistics box, thereby improving the lifting efficiency of the logistics box when the lifting mechanism is used;
