Electric curtain

Abstract

The invention discloses an electric curtain which comprises a bracket, a fixed seat, a driving device and a pull ring, wherein the fixed seat is arranged at two ends of the bracket; the bracket is a seamless tube body; the pull ring is sleeved outside the tube body; the driving device is arranged in an inner cavity of the bracket tube body; the driving device comprises two guide rails, two guiders, two speed reducing motors and a constant voltage / constant current power supply, wherein the guide rails are driven by the speed reducing motor to rotate and drive the guiders to travel left and right along the guide rails; a magnet is inlaid on the top surface of each guider; the magnet corresponds to a permanent magnet on the inner surface of the pull ring outside the tube body; the guiders which move left and right attract the pull ring to synchronously move on the tube body; a wiring guide tube is arranged through fixing blocks in the middle and at two ends and the two guiders; and the connection of all circuits is arranged in the wiring guide tube. The invention has the advantages of lower operation noise and compact and esthetic overall appearance, the curtain and a transmission mechanism are synchronously operated, the speed reducing motor uses a DC12V power supply, so that the use safety is ensured, and when the power is cut off, the curtain can be opened and closed by hand.

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 towards electrification and intelligence. The curtains used by most people are electric remote control, but the existing electric curtains have the following disadvantages: [0003] 1. The diameter of the rod body of the curtain bracket is large, and there is a gap in the rod body. The noise during the working process of the motor and the transmission system will come out from the gap. The increase will affect the normal operation of the driving device, and the rod body will have gaps and the wiring of the circuit will be exposed, which is not beautiful; [0004] 2. The pulleys of most curtains are pulled by belts or wire ropes. The electric curtain pulleys driven by belts are prone to slipping and lost rotation, and the belts a...

Problems solved by technology

[0007] The main purpose of the present invention is to solve the problem that the existing electric curtain bracket is a pipe body with seams, resulting in relatively high noise;

[0008] Another purpose of the present invention is to solve the problem that the rod body of the existing electric curtain is thick, resulting in poor overall appearance;

[0009] Another object of the present invention is to solve the problems of the existing electric curtains using belts or wire ropes for slipping, frequent maintenance and inconvenient use if they are lost;

[0010] Another purpose of the present invention is to solve the problem that the power supply of the existing electric curtains is unsafe to use with alternating current and inconvenient to use when the power is cut off.
