The invention provides a multi-gear electric drive axle structure which is free of gear shifting power interruption, good in driving feeling and free of car sliding risk. The mass distribution is reasonable, the center of mass is close to the axle housing axis, the cantilever is short, and the stress and vibration conditions are greatly improved; the structure is compact, and the whole vehicle arrangement is simple; the gear expansion modes are rich, the electric drive axle adapts to various complex working conditions, and the overall energy consumption of the electric drive axle is low. The device comprises an A-side power input assembly; a B-side power input assembly; the front-row planet row assembly comprises a front-row sun gear, a front-row planet gear, a front-row inner gear ring and a front-row planet carrier; the first and third gear shifting assembly comprises an inner gear ring gear hub, a gear shifting sliding sleeve, a fixed combination gear and a planet carrier combination gear; the rear-row planet row assembly comprises a rear-row sun wheel, a rear-row planet wheel, a rear-row inner gear ring and a rear-row planet carrier; the differential mechanism assembly comprises a differential mechanism, a left half shaft and a right half shaft; the left half shaft and the right half shaft are respectively and fixedly connected with the differential mechanism; and the front-row sun wheel shaft assembly comprises a hollow front-row sun wheel shaft and an input constant meshing tooth.
