Electric curtain

Abstract

The invention discloses an electric curtain, wherein the mounting frame of the electric curtain is a box body; a transverse diaphragm plate is used to divide the box body into an upper part and a lower part; a vertical diaphragm plate is used to divide the upper part into a mounting chamber and a wiring chamber; the lower part of the box body is provided with a chute; the entire drive device is arranged in the sealed mounting chamber of the upper part of the box body, the drive device consists of a guide way, guiders, a gear motor and a variable voltage power supply; the guide way is driven by the gear motor to rotate and drive the two guiders to perform reverse movement or relative movement along the guide way; the bottom surface of each guider is provided with a permanent magnet; two pulleys are arranged in the chute of the lower part of the box body; a magnet is embedded in the top surface of each pulley; the magnet and the permanent magnet at the bottom of each guider are opposite and attract to each other; the guiders move left and right on the guide way and attract the pulleys to slide left and right in the chute; the guide way and the guiders are made from engineering plastic; and the threads on the guide way are multi-start trapezoidal threads. The electric curtain has low running noise, small volume and convenient mounting method; the curtain can move to an assigned position for opening or closing; and the electric curtain is safe to use.

Description

technical field [0001] The invention relates to a curtain, in particular to an electric curtain. Background technique [0002] At present, with the improvement of people's living standards, the living facilities in the house are gradually developing in the direction of electrification and intelligence. Most of the curtains used by people use electric remote control, but the existing electric curtains have the following shortcomings: [0003] 1. Most curtains are pulled by belt or wire rope connection. The drive motor is installed outside the mounting frame, and the internal transmission system of the slide rail is open, resulting in loud noise during the opening and closing of the curtain, which affects people's rest. Interfering with people's lives, the easy entry of dust in the slide rail increases the friction of running parts, which seriously affects the use effect and service life of electric curtains. [0004] 2. The drive motors of some electric curtains are set outs...
