Abstract
The utility model relates to a driving system of an automatic curtain machine, which uses a high performance Low-speed permanent-magnet synchronous motor for direct drive and removes a mechanical transmission structure. The utility model has the advantages of simple structure and small size. The reelable wire part of the driving wheel fixed on the motor output shaft is a concave surface, and the curtain drawing wire of the driving wheel is the closed ring form. The drawing wire is wound with loops from 3 to 8 on the driving wheel, and the diameter of the driving wheel is small; the pulling force output from the drawing wire is stronger, and the drawing wire is not easy to be damaged. The utility model has the advantages of simple structure, compact structure, and convenient use.
Description
The utility model relates to a kind of automatic curtain machine drive system.Particularly a kind of automatic curtain machine drive system that has the driving wheel device.
The automatic curtain machine drive system that prior art is produced has two big classes, and a class is the linear electric motors drive systems, and another kind of is that high-speed rotary motor is through decelerator reduction of speed drive system.For the linear electric motors drive system, the whole framework of window curtain driving mechanism is as the part of motor, and its shortcoming is manufacturing, transportation difficulty and cost height, is difficult for producing many specifications product of different in width that application is restricted.High-speed rotary motor is through decelerator reduction of speed drive system, generally by drive motors, decelerator, driving wheel, backguy and auxiliaryly constitute with elements such as pulleys.This class drive system has a driving wheel on reducer output shaft, drive backguy by this driving wheel, backguy pulling curtain opening and closing.For making driving wheel can pass to the enough big pulling force of backguy, generally be the driving wheel diameter do very big; Perhaps driving wheel is made gear, pinwheel etc., and this makes, and entire mechanism is huge, complex structure, cost height, noise are big, difficult in maintenance, also is difficult for applying.
The purpose of this utility model just is intended to solve above-mentioned the deficiencies in the prior art.
The utility model automatic curtain machine drive system realizes by the following method: drive motors has adopted the high-performance Ne-Fe-B constant magnetism low-speed synchronous motor, on the shaft extension of motor driving wheel is housed, drive motors and driving wheel are contained in a side of window curtain driving mechanism, and a fixed pulley is adorned in the opposite side relevant position.The curtain backguy is a closed annular.It is wound with some circles back and walks around fixed pulley through the opposite side of window curtain driving mechanism and return the driving wheel closure on driving wheel.Backguy links to each other with curtain with straight line appropriate location between the fixed pulley at driving wheel, pulling curtain synchronously during its motion.Though the driving wheel diameter is little, because backguy is wound with some circles on driving wheel.This has just increased widely and has driven frictional force between wire-drawing wheel.Promptly when motor rotated, driving wheel drove the bigger pulling force of backguy output, required pulling force in the time of can satisfying the open and close curtain.
Driving wheel of the present utility model is the single-revolution body, but the bus on its winding portion surface is a curve.This curve is a matrix, and promptly the radius of gyration at two is greater than the middle radius of gyration.General bus is the combination of circular arc or circular arc, also can be the combination of broken line and curve.Concavity is too big, can make around the backguy of going into driving wheel to concentrate the middle lowest part slide into driving wheel to hang, and concavity is too little, can't slide into the centre of driving wheel at any time again and hangs at side around the backguy of going into driving wheel.Show that according to test the angle of the bus two ends extended line of the general recessed curved surface of driving wheel is between the 160---174 degree.
Backguy on the driving wheel around the number of turns be that maximum pull required when moving with window curtain driving mechanism is relevant, invalid slip does not take place for window curtain driving mechanism can normally be moved in use, around the number of turns can not be very little, but the number of turns also can make backguy arrange not open on driving wheel too much and hang phenomenon, various window curtain driving mechanisms generally speaking, backguy on driving wheel around the number of turns be that 3--8 circle effect is best.
When motor was rotated in the forward, driving wheel and motor forward rotated synchronously, backguy this moment from side of driving wheel by around going into driving wheel; Because recessed song was located in the middle of the effect of the recessed curved surface of driving wheel, backguy slided to driving wheel successively evenly.Emit from another side again.Draw back curtain with backguy pulling curtain this moment; In like manner, when the motor counter-rotating, this system is the curtain drawing.
According to the driving wheel of the automatic curtain machine drive system of the present utility model of above-mentioned design,, backguy on driving wheel makes that can produce enough frictional force drives curtain and finish the opening and closing motion owing to being wound with a few.Simultaneously because the surperficial recessed song of driving wheel can make after the backguy of going into driving wheel can slide to the driving wheel centre in time, in an orderly manner discharges, thereby well solved backguy undercapacity in the prior art and the shortcoming of twisted wire has taken place easily.Prolonged the service life of backguy again greatly.
In addition, driving does not need gear with constant magnetism low-speed synchronous motor but directly drives window curtain driving mechanism.
Below in conjunction with accompanying drawing the utility model automatic curtain machine drive system is further described:
Description of drawings:
Figure: among the automatic curtain machine drive system schematic diagram figure: (1). driving wheel (2). low speed permanent magnet synchronous motor (3). backguy
(4). fixed pulley
As shown in the figure, the endoporus of the driving wheel (1) of the utility model automatic curtain machine drive system directly is connected with the shaft extension of low speed permanent magnet synchronous motor (2), driving wheel (1) but winding portion be the single-revolution body, its bus is one section circular arc in the present embodiment, the formed angle of extended line of two outer ends of circular arc is 166 degree, and backguy (3) is wound with 5 circles on driving wheel (1).As can be seen from the figure, backguy (3) is a closed annular, and is wound with 5 circle backs on the driving wheel (1) and walks around fixed pulley (4) through the opposite side of window curtain driving mechanism and return driving wheel (1) closure.Backguy links to each other with curtain with appropriate location between the fixed pulley (4) at driving wheel (1), pulling curtain synchronously during its motion.When motor (2) rotates, because driving wheel (1) and motor (2) rotation synchronously, between backguy (3) on the driving wheel (1) and driving wheel (1) enough frictional force is arranged, backguy this moment (3) from side of driving wheel (1) by around going into driving wheel (1), and because the effect of the recessed curved surface of driving wheel (1); Backguy (3) slides to the middle recess of driving wheel (1) successively evenly, discharges from another side again.This moment, the window curtain driving mechanism that links to each other with backguy (3) just finished that curtain draws back or closure.
Claims (3)
1. one kind by drive motors, driving wheel, backguy and auxiliaryly constitute the automatic curtain machine drive system with elements such as pulleys, adopt the high-performance low speed permanent magnet synchronous motor directly to drive, it is characterized in that: but the winding portion surface that is fixed on the driving wheel on the synchronous motor output shaft is a rotary body that bus is a curve, this bus is a matrix, and the different buses according to driving wheel and backguy are the combination of circular arc or circular arc, also can be the combinations of broken line and curve.
