Description

Technical Field

[0002] Electric curtains mainly include motors, transmission boxes and tracks. The motor drives the synchronous pulley in the transmission box to rotate, thereby driving the synchronous belt in the track to move. The synchronous belt movement drives the pulley connected to the curtain cloth to move, thereby realizing the opening and closing of the curtain. Among them, hidden electric curtains are becoming more and more popular because they can save space without destroying the decoration style of the house.
