Description

TECHNICAL FIELD

[0001] The utility model relates to a drive device underlay's honeycomb 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.

[0003] The existing electric honeycomb curtain has a battery, a motor and a rope winding device installed in an upper beam, and the rope winding device is driven to rotate by the motor to realize the lifting of a 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.
