The invention discloses a gearbox structure for an electric long slide rail, which comprises a box body, an input gear shaft, an intermediate gear shaft and a transmission gear shaft are arranged in the box body, an input gear is arranged on the input gear shaft, an intermediate gear is arranged on the intermediate gear shaft, the input gear is meshed with the intermediate gear, and the transmission gear shaft is meshed with the intermediate gear. The transmission gear shaft comprises a gear part and a spline part which are of an integrated structure, the gear part is located in the box body, a transmission gear meshed with the intermediate gear is arranged on the gear part, the spline part extends out of the box body, an output gear is connected to the spline part, and the output gear is connected with the transmission gear. The output gear is connected with the spline part through a spline in a matched mode. And not only can the stable operation of the long sliding rail be realized, but also the transmission clearance of the gear box is reduced to the greatest extent.
