[0020] The belt drive assembly 3 is used to drive the transmission belt 4 to reciprocate. The transmission belt 4 is of a closed - loop design;

[0021] When the transmission belt 4 drives left and right, it drives the sliding door linear movement connection assembly 2 to move left and right;

[0022] Positioning is carried out by meshing the transmission belt 4 with the upper and lower upper transmission gears 5 and lower transmission gears 6 to prevent it from disengaging from the meshing of the upper transmission gear 5 and the lower transmission gear 6;

[0023] The uniform speed protection structure 7 controls the rotation speed of the lower transmission gear 6, thereby realizing the control of the transmission speed of the transmission belt 4 and realizing the uniform control of the left - and - right movement of the sliding door linear movement connection assembly 2.

[0024] The sliding door linear movement connection assembly 2 of the present utility model includes a linear pulley groove 201 and a sliding connection member 202 arranged on the drive frame 1. A sliding wheel 203 is arranged on the sliding connection member 202. The sliding wheel 203 is movably installed in the linear pulley groove 201.

[0025] The belt drive assembly 3 of the present utility model includes a belt drive motor 301 and a plurality of belt positioning drive wheels 302. The transmission belt 4 is connected to the belt drive motor 301 and a plurality of the belt positioning drive wheels 302 for movement.
