Multi-stage transmission output mechanism and electric vehicle applying multi-stage transmission output mechanism

The utility model discloses a multi-stage transmission output mechanism. The device comprises a motor and two or more transmission assemblies which are connected in sequence, each transmission assembly comprises a driving disc, a transmission belt, a driven disc and an output shaft. The surface of the output shaft is sleeved with the driven disc, the surfaces of the driving disc and the driven disc are sleeved with the transmission belt, the output end of the motor is sleeved with the driving disc of the first transmission assembly, and the surface of the output shaft of the previous transmission assembly is sleeved with the driving disc of the next transmission assembly. The utility model discloses a multistage transmission output mechanism. The motor outputs through multi-stage transmission; the output torque of the motor can be distributed for one-time transmission conversion and two-time transmission conversion or N-time transmission conversion; therefore, the output torque of themotor can be improved, la
