Description

TECHNICAL FIELD

[0001] The utility model relates to an electric curtain. BACKGROUND

[0002] The electric honeycomb curtain is a curtain system driven by a motor to realize automatic opening and closing, and the internal structure adopts a honeycomb-shaped pleat design, which has good heat insulation and sound insulation effects. The electric day and night honeycomb curtain is composed of two independent honeycomb curtains, one of which is a day curtain mainly used for blocking sunlight, and the other is a night curtain mainly used for providing privacy and heat preservation. Each curtain can be independently controlled, and users can flexibly adjust according to needs.

[0003] The existing electric day and night honeycomb curtain has a battery, a motor and a rope winding device installed in the upper beam, and the rope winding device is driven to rotate by the motor to realize the lifting of the lower beam. Although the lithium battery has a long service life, its capacity will gradually decrease over time. When the battery is insufficient or needs to be replaced, the user must charge or replace the battery. Since the battery, motor and other key components are located in the upper beam at the top of the curtain, the user must climb above the window when charging or replacing the battery. This process is not only extremely inconvenient, but also may cause safety hazards. In addition, with the frequent use of the electric honeycomb curtain, the pull rope in the rope winding device may gradually stretch due to friction and tension. This not only affects the overall appearance of the curtain, making the lower beam look tilted and uneven, but also causes the lower beam to be stuck with the side rail when moving, hindering the normal opening and closing operation.
