Description

Multi-functional automatic curtain machine

Curtain is practical items important in the family, can be used to regulate indoor light, simultaneously, has good ornamentally, and traditional curtain is mainly by manual operation.Along with the raising of living standards of the people, the application of large-scale curtain more and more widely.Though large-scale curtain can fully play the effect that beautifies the room, its operation is difficulty relatively.Now have the mechanism of some auxiliary operation curtain for head it off, mainly contain pure manually and electronic two kinds: man-operated mechanism is along the slide rail of settling curtain transmission rope to be set, and transmission rope is turned to pulley, make the operator can utilize the switching of transmission rope control curtain at lower position; Electric curtain mechanism is to set up motor on the hand gear basis, makes the effector can utilize power switch operation curtain, and the weak point of existing various schemes is all can not realize automatic control.

The purpose of this utility model is to provide a kind of multi-functional automatic curtain machine, can realize the automatic control of curtain.

Scheme described in the utility model is that this multi-functional automatic curtain machine is made up of main frame, subsidiary engine, Curtain rail, transmission rope, alternating current generator and control circuit.Wherein control circuit comprises sensor, voltage comparator circuit and relay, often the opening of relay, just commentaries on classics end and counter-rotating end that the normally-closed contact switch is connected to alternating current generator, sensor is connected an input of voltage comparator, and another input of comparator connects a standard voltage source.Be provided with touch-switch near curtain rail, corresponding position is provided with the contact on transmission rope simultaneously, and transmission rope is in the rotating shaft of alternating current generator.Described sensor can be various sensors such as light sensor, heat-sensitive sensor, pneumatic sensor

Advantage of the present utility model is can be according to using on-the-spot light, temperature to reach the automatic control that situations such as whether wind is arranged realize curtain.The circuit structure that the utility model adopted is simple, reliable operation, cost are low, be suitable for large-scale batch process.

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1: structural representation of the present utility model.

Fig. 2: the circuit diagram of a kind of embodiment of the utility model.

Fig. 3: the schematic diagram of the man-operated mechanism that is adopted in the present embodiment.

Example: this routine described window curtain driving mechanism comprises main frame 8, secondary machine 1, two steel wires 10 that are connected with transmission rope 4 between the major and minor machine and use as curtain rail, the two ends of this two steel wire 10 are connected on the major and minor machine 8,1, and it is stretching with bolt 2, alternating current generator 7 is installed on the main frame 8, its rotating shaft is vertically installed, and a reel 6 is fixed on this rotating shaft top.On secondary machine, establish a pulley 3 with the position of reel 6 symmetries, transmission rope 4 is provided with a microswitch K1 and a K2 near transmission rope 4 places on reel 6 and pulley 3, and corresponding position is fixed with stroke contact 5 on transmission rope 4.Be used to control circuit that motor 7 rotates as shown in Figure 3.The sensor that is adopted in this example is phototriode D, described voltage comparator circuit IC1 is a LM393 device, described photosensitive tube D be connected between power vd D and the ground after resistance R 1 is connected, node between photosensitive tube D and the resistance R 1 is connected the in-phase end of this LM393 device simultaneously, the backward end of LM393 device is connected with standard voltage source, institute's accepted standard voltage source is that two ends are connected the adjustable resistance RW between power vd D and the ground in this example, utilize this resistance R W can adjust the threshold voltage of entire circuit, promptly control the sensitivity of entire circuit.The output of above-mentioned voltage comparator ic 1 is connected with the control end of relay J 1 by triode NI, the motor section parallel circuit as shown in the figure in this example, relay J normal battle JK1 with the just commentaries on classics end that is connected alternating current generator M after microswitch K1 connects, JK2 and K2 are connected in the counter-rotating end of M.For ease of maintenance, this routine described control circuit is installed in one independently in the circuit box 9, and this circuit box 9 is movably connected on the main frame.

This routine described window curtain driving mechanism also has the various control function.They realize that by four K switch K1, KK2, KK3, KK4 and relay J 2 relay J 2 is connected between power vd D and the ground, and the normally opened contact of this relay J 2 is connected between alternating current generator and its power supply.Described four switches are installed in the control box, so that the operator uses, wherein K switch K1 is connected between relay J 1 and the triode N1, and KK2 is a neutral gear, and KK3 is connected between relay J 1 and the ground.K switch K4 is connected between relay J 2 and the ground.

Its course of work is:

1, control: K switch K1 connects automatically, this window curtain driving mechanism can be controlled Curtain switch automatically according to outdoor light intensity, and when light was strong, the resistance of phototriode D reduced, the in-phase end voltage of voltage comparator ic 1 is raise, when this voltage was higher than the end of oppisite phase voltage that is determined by adjustable resistance RW, voltage comparator ic 1 output high level made the N1 saturation conduction, relay J 1, normally opened contact JK1 connects, and alternating current generator just changes, and drives curtain and opens.When curtain was fully opened, touch-switch K1 was touched in the stroke contact, and K1 is disconnected, and motor quits work.When light is weak, voltage comparator ic 1 output low level, N1 ends, the relay J power down, normally-closed contact JK2 connects, and curtain is closed in the alternating current generator counter-rotating, and the contact moves away touch-switch K1 simultaneously, and it is ready that K1 is connected to opening curtain next time.After curtain was fully closed, K2 disconnected, and motor quits work.

2, curtain: the K switch K3 that manually windows connects, and relay J gets electric, and curtain is opened.

3, hand window-closing window curtain: K switch K2 connects, and the relay J power down is closed curtain.

4, stop motion in the operating process: K switch K4 connects, and relay J 2 gets electric, and its normally-closed contact J2K disconnects, and the alternating current generator outage quits work.

Still can operate easily when having a power failure for making window curtain driving mechanism described in the utility model, this routine described technical scheme also comprises an arrangement of clutch, this device comprises that being located near main frame 8 movable pulley 12 and manual operationss restricts 11, and this manual operations rope 11 is on described movable pulley 12.Simultaneously, the fixedly connected spur gear 13 in the upper end of motor shaft, the outside of this spur gear is set with clutch cover 16, the inboard of this clutch cover is provided with the straight-tooth that mates mutually with this spur gear 13, the lower end in this clutch cover outside also is provided with straight-tooth, described reel 6 is sleeved on this clutch cover 16 outsides, and utilizes straight-tooth to cooperatively interact.The below of described clutch cover 16 is provided with back-moving spring 17, and the top of clutch cover 16 is provided with a wedge 14, and an end of this wedge utilizes spring 15 to be connected on the main frame 8, and the other end is connected with movable pulley 12.Pulling manual operations rope 11 o'clock, pulling force acts on the movable pulley 12 and logical moving this pulley drive wedge 14 is moved to the left, utilize the inclined-plane of wedge 14 that clutch cover 16 is depressed, can so that reel 6 break away from motor shaft, thereby can realize by hand direct control curtain easily.After above-mentioned pulling force disappeared, wedge 14 and clutch cover 16 automatically reset under the effect of
