[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] The drive motor drives the worm gear in the gear box to rotate through the flexible shaft. The worm gear engages with the lead screw so that the gear box can move linearly along the lead screw. The gear box drives the upper slide rail, and the upper slide rail drives the entire seat body to move, realizing the electric lateral movement of the seat. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The present invention will be further described below in conjunction with the accompanying drawings.

[0016] like Figure 1 、 2As shown, an electric side-shift car seat is used as a seat on the side of a bus close to the aisle, which includes a seat body 1, a support frame 2 supported on the bottom of the seat body 1, a sliding mechanism 3 provided between the seat body 1 and the support frame 2 for the seat body 1 to slide laterally, and a drive motor 5 for driving the sliding mechanism 3. Sliding mechanisms 3 are provided at the front and back of the bottom of the seat body 1. The two sliding mechanisms 3 are arranged in parallel. The two sliding mechanisms 3 jointly support the seat body 1, and the sliding direction of the sliding mechanism 3 is perpendicular to the orientation of the seat. The sliding mechanism 3 includes a lower rail 32 fixed on the support frame 2, an upper rail 31 fixed on the seat body 1 and slidingly matched with the lower rail 32, a screw rod 33 and a gear box 34 sleeved on the screw rod 33.
