The invention provides a multi-gear electric drive axle driving structure and a vehicle. According to the multi-gear electric drive axle driving structure, the two ends of a first connecting shaft are connected with a motor and a first gear transmission assembly; the two ends of the second connecting shaft are connected with the first gear transmission assembly and the second gear transmission assembly. The third gear transmission assembly is in meshed connection with the second gear transmission assembly, the third gear transmission assembly is connected with a third connecting shaft, and the third connecting shaft and the first connecting shaft are coaxially arranged; the fourth gear transmission assembly is in meshed connection with the third gear transmission assembly, and the fourth gear transmission assembly is connected with the fourth connecting shaft; the fifth gear transmission assembly is in meshed connection with the fourth gear transmission assembly, and the fifth gear transmission assembly is connected with a fifth connecting shaft through a differential mechanism; the two ends of the fifth connecting shaft are used for being connected with the first driving wheel and the second driving wheel correspondingly. According to the driving structure, the gear transmission stage number and number are reduced, the transmission efficiency is improved, the arrangement space is shortened, and the weight is reduced.
