The invention discloses an automobile seat electric long sliding rail which comprises two sets of upper sliding rails and lower sliding rails corresponding to the upper sliding rails, the upper sliding rails are assembled on the corresponding lower sliding rails in a front-back sliding mode through lead screw nut mechanisms, and transfer gear boxes are installed on the upper portions of the upper sliding rails. A longitudinal transmission shaft is connected between the transfer gear box and the lead screw nut mechanism, a support is fixedly installed between the two sets of upper sliding rails, a horizontal transmission shaft is rotatably installed on the support, the two ends of the horizontal transmission shaft are both in power connection with the transfer gear box, and a motor is installed on the support. An output shaft of the motor is perpendicular to the horizontal transmission shaft, and a speed reduction transmission assembly is arranged between the output shaft and the horizontal transmission shaft and used for reducing the input rotating speed of the transfer gearbox. The invention has the technical advantages of low operation noise, small vibration, good smoothness and the like.
