1. An electric slide rail comprising:
a track system;
a power assembly; and
a transmission system;
wherein the track system comprises an upper rail, a middle rail, and a lower rail arranged from top to bottom,
the power assembly is fixed to the lower rail,
the transmission system is fixed to the middle rail,
and the electric slide rail is configured such that the power assembly provides power to move the track system via the transmission system;
wherein the power assembly comprises a motor and a power wheel, and the power assembly is configured such that when powered, the motor starts operating, driving the power wheel to rotate;
wherein the transmission system is configured as a transmission rack, and the transmission rack meshes with the power wheel;
further comprising a front synchronous wheel, a rear synchronous wheel, and a synchronous belt,
wherein both the front and rear synchronous wheels are fixed to the middle rail,
and the synchronous belt is attached to the upper and lower rails through upper and lower fixed components, respectively;
wherein the position of the transmission rack and the synchronous belt are on the same side of the middle rail.
