[0055] The above-mentioned curtain drive is divided into left-side design and right-side design. The structures of the curtain drives of the two designs are different. When purchasing electric curtains, users need to choose the installation location of the curtain drive, and then the merchant will deliver the curtain drive of the corresponding design according to the user's needs. It is precisely because of the different structures of the left and right curtain drives that the delivery error problem is prone to occur. At the same time, the non-interchangeable curtain drives also greatly increase the production and storage costs.

The curtain driver with bidirectional power output as claimed in claim 13, characterized in that: The front connection structure also includes a wing plate horizontally arranged on the curtain driver, the wing plate extends outward from the side wall surface of the curtain driver, the first convex groove is formed at the head of the wing plate, and the second convex groove is formed at the tail of the wing plate.

15. The curtain driver with bidirectional power output as claimed in claim 14, characterized in that: The wing plate includes a stopper located at the rear, which is used to cooperate with the elastic ejector of the transmission box, and includes a guide surface and a placement surface; when the curtain drive is fixed to the transmission box in the vertical direction, the placement surface supports the elastic ejector.

16. The curtain driver with bidirectional power output as claimed in claim 15, characterized in that: The tail end connection structure includes an elastic buckle plate arranged at the tail end of the driver housing, the elastic buckle plate includes a reset spring, and the elastic buckle plate also includes a buckle symmetrically arranged relative to the driver housing, the buckle is arranged downward, and the buckle is used to extend into the corresponding slot of the curtain profile and stop above the slot.

17. An electric curtain, comprising a curtain transmission box, characterized in that: It also includes a curtain drive with bidirectional power output as described in any one of claims 1 to 16.

18. The electric curtain according to claim 17, characterized in that: The curtain transmission box includes a right transmission box and a left transmission box, the first output gear is used to mesh with the first input gear of the right transmission box of the curtain; the second output gear is used to mesh with the second input gear of the left transmission box of the curtain.
