The electrically-driven speed change mechanism comprises a first motor, a first transmission shaft, a second transmission shaft, a gear reducer, a speed reduction assembly, a main speed reducer and a differential mechanism. The gear reducer is arranged between the first transmission shaft and the second transmission shaft; the main reducer is arranged between the second transmission shaft and the differential mechanism; the speed reduction assembly comprises a planet row speed reducer arranged on the first transmission shaft, a first clutch and a second clutch, the first clutch is arranged between a fixing piece and a gear ring of the planet row speed reducer, the second clutch is arranged between a planet carrier of the planet row speed reducer and a sun gear, and the fixing piece and the first motor are relatively fixed. The electrically-driven speed change mechanism can increase the number of gears of the pure electric vehicle, the use flexibility of the pure electric vehicle is improved, space arrangement is facilitated, and the user experience can be improved.
