[0026] Reference Figures 1-5 The utility model one embodiment shows a kind of traction assembly for electric window curtain machine, the traction assembly is arranged on window curtain rail 100, including the mobile body 1 of sliding setting on window curtain rail 100, transmission wheel 2 and the driver 3 for driving the rotation of the transmission wheel 2 are equipped on the mobile body 1, at least part of the transmission wheel 2 protrudes from one side of the mobile body 1, and the other opposite side of the mobile body 1 is provided with protruding portion.

[0027] For the convenience of understanding the structural advantages of the above-mentioned traction assembly, please refer to Figures 3-5, shows the curtain rail 100, two conductive strips 200 are provided at the top inside the curtain rail 100, and a transmission belt 300 is provided on the inner side of the curtain rail 100. In this embodiment, the driver 3 is a motor, and the moving body 1 is further provided with a conductive contact 5, which is electrically connected with the motor. In operation, the conductive contact 5 is in sliding contact with the conductive strip 200 and forms an electrical connection; by changing the positive and negative poles of the conductive strip 200, the forward and reverse rotation of the motor can be controlled, the motor drives the transmission wheel 2 to rotate, and the transmission wheel 2 is engaged with the transmission belt 300, so that the moving body 1 can move along the curtain rail 100. The working principle can refer to the prior art CN217659190U or CN201263033Y.

[0028] In this embodiment, as shown in Figure 4 , the transmission wheel 2 is arranged on one side of the moving body 1, and a protruding portion is arranged on the other side, which abuts against the inner side wall of the curtain rail 100, so as to ensure that the transmission wheel 2 is pressed on the transmission belt 300, avoiding disengagement of the transmission wheel 2 from the transmission belt 300, and through the left and right distribution of the synchronous wheel and the protruding portion, the left and right swinging of the moving body 1 during movement can be avoided, and the movement stability of the moving body 1 is improved.
