Description

A kind of electrically driven curtain

Technical field

The present invention relates to a kind of curtain, particularly a kind of electrically driven curtain.

Background technology

At present, the Along with people's growth in the living standard, living facilities within doors are gradually to electrified and intelligent direction development, and other used curtain of majority all adopt electric remote control, but the prior electric curtain has the following shortcoming:

1, the body of rod diameter of Curtain rod is thick, and the body of rod leaves the slit, and the noise in motor and the driveline process can spread out of from the slit; Noise is bigger; And dust gets into the body of rod from the slit inner, causes the frictional force of slipper to increase, and influences the operate as normal of drive unit; The body of rod has the line of slit and circuit to expose, and is not attractive in appearance;

2, the coaster of most curtain adopts belt or steel wire rope connection to spur; The phenomenon of skidding, throwing switch appears with bel-drivenn electrically driven curtain belt pulley easily; And belt is prone to aging, is not durable, and uses the coaster of steel wire rope pulling; Noise needs often maintenance oil injecting lubricating than big and rotatable parts, uses not convenient;

3, the power supply of electrically driven curtain majority is an AC power, wastes energy, and uses dangerous;

4, most electrically driven curtains need break off clutch earlier in case of having a power failure, and again with manually drawing back, and need establish manual stay cord in the relevant position, and not attractive in appearance, it is very inconvenient to use during power failure.

Summary of the invention

Main purpose of the present invention is to cause the bigger problem of noise in order to solve existing electrically driven curtain support for the seamed pipe body;

Another object of the present invention is thick for the body of rod that solves existing electrically driven curtain, causes the relatively poor problem of overall appearance property;

A further object of the present invention is to use belt or steel wire rope transmission to produce the often maintenance of skidding, throw switch, awkward problem in order to solve existing electrically driven curtain;

Another purpose of the present invention be for the power supply that solves existing electrically driven curtain be alternating current use go up dangerous when having a power failure inconvenient problem with use.

In order to address the above problem, the present invention provides a kind of electrically driven curtain.

Electrically driven curtain of the present invention is made up of support, holder, drive unit and draw ring, and holder is located at the two ends of support, and support is a seamless tube body; Draw ring is enclosed within outside the body, and the inner surface that draw ring contacts with body is inlaid with permanent magnet, and drive unit is located in the tube cavity of support; Drive unit is made up of guide rail, guider, reducing motor and motor positive and inverse remote control control module and variable-voltage power supply, and on the fixed block in the middle of the mid portion of guide rail is articulated in, the two ends of guide rail are articulated on the fixed block at two ends; Be provided with one or two reducing motor, reducing motor is installed in the motor mounting pipe, and motor positive and inverse remote control control module and variable-voltage power supply are located in one of them motor mounting pipe; The bottom of this motor mounting pipe is provided with plug, and the motor mounting pipe is provided with two sealing rubber rings, makes the motor mounting pipe put into combine with internal chamber wall in the tube cavity tightr; Do not vibrate when making reducing motor work, be provided with shaft coupling between the motor mounting pipe at two ends and the fixed block at two ends, shaft coupling is an elastomer; One end of each shaft coupling connects with the interior reducing motor of motor mounting pipe, and the other end of shaft coupling connects with guide rail through fixed block, and the shaft coupling at motor mounting pipe, two ends is coaxial setting with guide rail; Reducing motor rotates through the shaft coupling driving guide rail that links with it, and guide rail is a screw-rod structure, and the screw thread on the left-half guide rail is a left hand thread; The guide rail of right half part is a right-handed thread, on the guide rail of left-half and right half part respectively spiral shell be provided with guider, guide rail rotates under the drive of reducing motor and orders about guider reverse or relative motion along guide rail; Screw thread on the guide rail is multi-thread trapezoidal thread, guider is accelerated, so along the translational speed of guide rail; Under identical guider translational speed prerequisite, the velocity of rotation of reducing motor can reduce greatly, and then makes the noise of reducing motor littler; The end face of guider is inlaid with magnet, this magnet and the body corresponding and mutual absorption of permanent magnet of draw ring inner surface outward, and the move left and right of guider attracts draw ring on body, to be synchronized with the movement; Make the curtain that is connected with draw ring carry out folding, in the both sides of center fixed piece and the installed inside of two ends fixed block limit switch is arranged, each limit switch is electrically connected with motor positive and inverse remote control control module and variable-voltage power supply; When guider touches limit switch, the reducing motor outage, reducing motor stops operating; Reach the purpose of automatic control, stopped the generation of the stall phenomenon of reducing motor, thereby prolonged the service life of reducing motor; Motor positive and inverse remote control control module and variable-voltage power supply are supplied power to reducing motor, and accept the telecommand of remote controller, and the input voltage of motor positive and inverse remote control control module and variable-voltage power supply is AC220V; Output voltage is DC12V, and the wiring guide pipe is located in the bottom of three fixed blocks and two guiders, and the two ends of wiring guide pipe are connected with the motor mounting pipe at two ends respectively; All circuit connection lines all are laid in the wiring guide pipe, and wiring guide pipe ability limit guides is along the body side-to-side movement.
