The invention provides an electric automobile seat. The electric automobile seat comprises a cushion support and side plate supports fixed to the two sides of the cushion support; retractable axle assemblies are fixed to the bottom ends of the side plate supports on the two sides correspondingly; the two retractable axle assemblies are slidably mounted on electric rails; and a first motor and a second motor are fixed between the two retractable axle assemblies, the first motor is electrically connected with the electric rails; and the second motor is electrically connected with the retractableaxle assembly. The structure is simple, maintenance is convenient, the maintenance cost and manufacturing cost are saved greatly, and meanwhile the lightweight design of the seat is met; and furthermore, rising and falling of the seat are achieved through the structure of the retractable axle assemblies, the manufacturing cost is saved, and meanwhile the pressure borne by an automobile chassis islowered.
