Abstract
The utility model relates to an electric device for opening and closing curtains, comprising a curtain rail, a driving wheel and a driven wheel which are arranged at both ends of the curtain rail, a transmission rope, a motor, etc. The utility model is characterized in that the lower pole shoe of the motor is manufactured singly; the pole plate of the motor is arranged in a housing; a stator winding and a rotor are arranged on the pole plate. Thus, the utility model breaks through the difficulty of the manufacture of a salient pole type synchronous motor with big power, obtaining the purposes of reliability, low price, convenience and practicability. The utility model can be widely used for the opening and the closing of various curtains, door screens and proscenium curtains, etc.
Description
The utility model belongs to a kind of curtain headstock gear that drags with synchronous motor.
Existing electrically driven curtain opening/closing device, or adopt the remote control linear electric motors, directly affect curtain to finish keying (for example number of patent application 92222353); Or affect the folding of curtain by transmission rope take-up and unwrapping wire in the driving wheel of double grooved pulley formula.Though the tractive force that the former tool is enough, when operation, switching motion is launched just as bullet, lack soft stationarity, and cost is higher; Though the latter can overcome the skid drawback of curtain when opening and closing, and easily causes transmission rope to laminate mutually in the coiling process, and influences the reliability that curtain opens and closes, and tractive force is less.
On the other hand, because existing salient pole type permagnetic synchronous motor system adopts the structure of the utmost point palm and shell integral manufacturing down, it is first punching out KanXing Ti, make the utmost point of inwardly the turning up palm of strip again in its bedplate upper punch, this has just limited the increase of utmost point palm height, brings the obstacle of some technologies and configuration aspects for larger capacity (about the 20 watts) making of motor.Therefore, this class motor generally only can be as the power of the little load below 3 watts (as electroclock etc.), and difficulty can drag curtain with it, especially the curtain of pleuche uniform thickness material system and stage curtain etc.
The purpose of this utility model is to provide a kind of and can steadily drags reliably than heavy load, makes it be parked in desired location arbitrarily, can overcome transmission rope again and skid and the electrically driven curtain opening/closing device that laminates the inexpensive practicality of drawback mutually.
The utility model mainly be the following utmost point palm that adopted a kind of special improvement design with the salient pole type permagnetic synchronous motor of shell branch system as opening and closing power, descend the utmost point to slap usually and the rope of the traditional structure of shell global formation is tied up thereby broken through this class motor.The following utmost point palm that is motor is made separately, and its pole plate flange is located in the shell, is provided with the rotor of stator winding and permanent magnetism at utmost point palm down, makes both increase height, becomes possibility thereby improve capacity motor.Simultaneously, for the magnetic resistance that the utmost point palm under overcoming may increase with the shell split production, can suitably thicken the thickness of pole plate and the height of pole plate flange.In addition, described shell can be the band KanXing Ti at the end, also can be ring set or the body of not being with the end.At bottom and/or the pole plate flange place of the following utmost point palm, can adopt methods such as screw, rivet, spot welding that both are combined closely with shell.Be provided with the transmission rope of arranged crosswise on by motor-driven driving wheel, like this, relatively or reverse motions, also increase v-belt contact angle simultaneously about Yun Hang transmission rope can be done simultaneously up and down.In case of necessity, can be provided with the drag ring that materials such as a rubber, sponge are made at the wheel trench bottom of driving wheel.Also can on transmission rope, be connected in series an extension spring,, prevent the generation of skidding to guarantee close contact of transmission rope and driving wheel etc.

Fig. 2 is a kind of electric machine structure figure of electrically driven curtain opening/closing device;
Fig. 3 is a kind of following utmost point palm seat board vertical view of salient pole type permagnetic synchronous motor;
Fig. 4 is the A-A cut-away view of Fig. 3;
Fig. 5 is a kind of driving wheel structure chart of electrically driven curtain opening/closing device.
The utility model specifically can be implemented like this: the right-hand member in guide bead (1), be provided with motor-driven driving wheel (9), the transmission rope of being put on it (5) is after intersecting, respectively from intersecting the loop that affects about the constituting with the driven pulley (2) of left end up and down of pulley (8).Wherein said department of electrical engineering adopts and affects moment to surpass the salient pole type permagnetic synchronous motor (20) that certain value can be auto-reverse.But,, can make some special improvement design: go out 6 following utmost point palms (11) with the pure iron plate punching out earlier, go out pole plate flange (23) with ring-like punch die punching out to realize the automatic reverse of curtain opening/closing device easily for this class micromachine can be diverted from one use to another in this.Laminated die with identical material extrudes the band Qian type shell (10) at the end in addition, after pole plate flange (23) is pressed into the shell of stationary fit, at bottom surface and pole plate flange place, makes both close proximity with spot welding.By stator winding (16) sleeve that makes around last enamel-covered wire on the nylon framework between the above-mentioned down utmost point palm (11) and shell (10), winding end to end with drawing, connect power supply (15) usefulness.Magnet steel with neodymium ferro-boron magnet sintering is through magnetizing into permanent magnet poles (14), and after arranging by designing requirement, with plastics such as polyformaldehyde they closely formed one together, rotor (13), the mold pressing simultaneously of one end goes out disjunctor gear (18).Behind the mandrel location of this rotor by the center, load onto the utmost point palm (19), the flange and the shell of the last utmost point palm are welded into one with mash welder again.And disjunctor gear and three grades of reduction gearing are slapped (19) by the last utmost point and the cover plate (17) loaded onto is thereafter gone up set axis hole location, and drive transmission rope (5) by the driving wheel on the output shaft (9) and finish the action that opens and closes curtain.In addition, can be provided with the drag ring (22) that a material such as rubber is made at the wheel trench bottom of driving wheel (9), and a serial connection extension spring (4) on transmission rope, to guarantee transmission rope and close contact of initiatively restricting, prevent the generation of skidding.When initiatively crop rotation clockwise rotated, transmission rope (5) was done relative motion respectively left and to the right about making like this, thereby made relative closing motion by curtain mobile terminal, the left and right sides (6) the drive curtain (7) that connects thereon.After mobile terminal (6) move to stiff end (3) and are obstructed when the closed tensioning of curtain or when opening, drag that resistance is anxious to be increased, make motor (20) auto-reverse, drive the curtain counter motion.When opening (or closed) to desired location, only need unclamp the button that connects power supply (15), cut off motor power and get final product, thereby realized the goal of the invention inexpensive, convenient, reliable, that drawing force is bigger.Wherein, production cost only is 1/3～1/5 of existing this series products of existing market.
