The invention relates to an electric drive axle structure which is installed on a differential mechanism and comprises a first drive part, a first rotating shaft, a first planet carrier, a wheel edge speed reduction assembly and a second drive part. The first rotating shaft is in transmission connection with the output end of the first drive part, and the first rotating shaft is fixedly sleeved with a first sun gear; the first planet carrier is fixedly sleeved with a first planet wheel, the first planet wheel is meshed with the first sun wheel, the differential mechanism is provided with two power input ends and two power output ends, and the first planet carrier is fixedly connected with one power input end. The two wheel edge speed reduction assemblies are connected with the two power output ends correspondingly, the output end of the second driving part is in transmission connection with the other power input end, power is not interrupted within the time from gear disengagement to successful gear shifting, the efficiency of a system is improved, and the electric drive axle structure is simple and compact, small in overall size and high in reliability. And arrangement and lightweight design of the whole vehicle are facilitated.
