PURPOSE: An up-and-down electric blind is provided to improve convenience by enabling a user to adjust the height of the blind. CONSTITUTION: An up-and-down electric blind comprises guiderails(10), a movable frame(20), a sunshade blind(22), a drive gear, a driven gear, a connection belt, and a drive motor(60). The guiderails are vertically installed in both sides of the blind. Both ends of the movable frame are supported to the guiderails, and the movable frame is moved along the guiderails. The length of the sunshade blind can be adjusted by winding the top end of the sunshade blade through a servo motor(21) installed inside the movable frame. The drive and driven gears are formed in the bottom and top ends of the guiderails. The connection belt connects the drive and driven gears to each other. The drive motor transfers power to the drive gear. |
