Description

Remote controller for shutter

The utility model provides a kind of remote control of sun blind, promptly controls drawing back with closed or lift corner with whereabouts and blinds of curtain by remote control, reaches the light-inletting quantity control of curtain.

The unlatching of existing sun blind and closure, are perhaps lifted and are fallen to realize drawing back and closure of sun blind normally by human control or driven by power sun blind rope, and the rotation of sun blind blinds.But the switch of this type of device generally all is fixed in certain, and the operator can't handle sun blind when needed easily, and must handle to fixing switch place.

The utility model aims to provide a kind of remote control of sun blind, and it can be controlled the rotation of sun blind and the switch of curtain integral body according to operator's intention by the infrared light that sends in the remote controller.

For this reason, the utility model provides a kind of remote control of sun blind, this device comprises signal emission part and according to its operation part that transmits sun blind are controlled, described signal emission part includes switch, and this switch links to each other with infrarede emitting diode by encoder, oscillator; Described operation part includes the drive circuit that can respond the signal that infrarede emitting diode sends, by drive circuit difference drive motors, motor draws back by gear and belt pulley drive blinds respectively or is closed, and, regulate light-inletting quantity by gear and the fixedly suspension hook rotation of blinds of worm and gear drive.

The remote control of sun blind of the present utility model has adopted incorporate design concept, and all parts are installed in the crossbeam of sun blind, as power supply, electronic circuit board, motor and transmission mechanism etc.This apparatus structure is simple, and is easy to maintenance, and operation is reliable.This device adopts battery powered mode, but also is provided with the socket and the parts thereof of external power supply simultaneously, can use civil power to power to this device.This device has been implemented standardized designs, and it both can carry out the control of single remote to single curtain, also can carry out the respectively control of single remote to a plurality of curtain, can also a plurality of curtain be controlled simultaneously.This device can be conveniently used on the curtain of all types of sun blind and other types.In addition, the special design part of this device can with existing any curtain series interfaces, this has improved the range of application of this device widely.

The purpose of this utility model, feature and advantage will be by being well understood in the description below in conjunction with accompanying drawing.

In accompanying drawing of the present utility model:

Fig. 1 has provided the block diagram of radiating portion, and wherein, the switch 1 of remote controller links to each other with the encoder 2 that has line of codes 5, and the output signal of encoder is delivered in the oscillator 3, drives infrared transmitter 6 by this oscillator 3 by drive circuit 4 again.

Fig. 2 is for accepting the theory diagram of part, and wherein receiving preamplifier 7 is delivered to signal in the decoder 9 of band line of codes 8, and these decoder 9 drive drive circuits 10 are handled

drive motors

11 and 12 respectively and rotated.

Fig. 3 has provided the emission circuit of remote control circuit.Radiating circuit is by integrated circuit G1(MC145026 for example), G2～G5(CD4011 for example), triode BG1, infrarede emitting diode D1 and D2(SE303A for example), button switch K 1～K4 and resistance and electric capacity etc. form, wherein G1 is an encoder, the oscillator that outputting encoded data diffluence control G2 and G3 form, this ring oscillator produces the square-wave signal of about 40KHz, after G4 and G5 are anti-phase, be added to the ground level of BG1, outwards launch through D1 and D2.On the remote controller except outside the Pass, generally also comprise K switch 1 to K4, that is, sun blind draw back K1; The closed K2 of sun blind; The blinds angle increases K3; The blinds angle reduces K4.When pressing on ﹠ off switch, the sun blind controller is in the minimum electricity condition of using; At this moment, if press the civil power formula outward, then cut off civil power.Receiver is by the power supply of reserve small-capacity cells, and this can save power consumption to greatest extent.During once more by this key, then recover former power supply mode.When pressing the K1 key, receiver receives control signal, and control sun blind drive motors just changes, and progressively draws the curtain apart.Then stop to draw curtain by this key once more.When pressing the K2 key, then being that sun blind are closed drives.In like manner, can control the angle of sun blind during by K3 or K4 key, control light-inletting quantity with this.

Fig. 4 is the receiving lines of remote control circuit.Receiving circuit is by integrated G6, G7(MC145027), G8～G11, triode BG2～BG3, light emitting diode D4, compositions such as infrared receiving diode D3 and resistance capacitance, wherein G6 is infrared receiving demodulation part, used special-purpose infrared preposition amplification circuit CX2016A, its inside comprises amplification, limits pass filter, integration relatively to wait circuit, and G7 is a decoder.When infrared transmitter is worked, receiver receives respective signal, the VT end of G7 is just uprised by low, bright the indicating of LED lamp D4 receives effectively, the D6 of decoder～D9 end is pressed along with K switch 1～K4 in the transmitter and high level occurred, these high level remove to trigger for example CD4013 of each self-corresponding flip and flop generator G8～G11(), and make motor action by drive circuit.

Fig. 5 has provided the drive circuit of motor, and it is by operational amplifier LM324, triode BG4～BG15, compositions such as diode D5～D10 and resistance capacitance.Wherein LM324 forms voltage comparator, adopts dual power supply, when flip and flop generator is output as low level, by relatively exporting one+5V voltage, makes the BG5 conducting, produces a negative voltage, makes the motor counter-rotating.When flip and flop generator was output as high level, comparator was output as-5V, and BG5 is ended, motor is failure to actuate, if this moment, another flip and flop generator was exported high level, produces a positive voltage, motor is just changeed, thus the driven gear running, and opening of sun blind of control closed rotation.

Shown in Fig. 6 a, motor 11 is through gear 15 driven wheels 16, and gear 16 is coaxial with belt pulley 17, and belt pulley 17 and belt pulley 19 surfaces have very big friction through handling.Rope pile

warp belt pulley

17 and 19 and pass the aperture 27 of curtain girder one side is fixed on the card 24.Spacing between the curtain girder is by 25 controls of stop bit bar.When motor 11 was executed electricity, motor then drove rope the curtain girder is equidistantly drawn back or closed with fixing, and blinds is fixed in suspension hook 26 places of curtain girder.Motor 12 is through

gear

23,22,20 driven wheels 21, and gear 21 assemblies are a deceleration assembly, by axle 28 outputs.Axle 28 is coaxial with worm screw 29, drives worm gear 30, and the curtain girder is coaxial with worm gear 30.When motor 12 is executed electricity, through the suspension hook 26 of series of gears, worm gear and worm drive curtain girder.Because blinds is fixed on the suspension hook, the rotation of suspension hook has driven blinds simultaneously, thereby has finished the adjustment of light-inletting quantity.Motor 12 is urged to rope and has passed through twice deceleration (gear reduction and rope slow down).Motor 12 is urged to the blinds suspension hook and has passed through three decelerations (gear reduction, gear 21 assemblies slow down and worm and gear slows down).The enlarged drawing of gear 21 assemblies is referring to A-A line sectional drawing-Fig. 6 b of Fig. 6 a; The matching relationship of worm gear 30 and worm screw 29 then can be referring to Fig. 6 c.

Below just describe a kind of possible embodiment of the present utility model with reference to the accompanying drawings.Certainly the utility model also can carry out suitable change to the structure of sun blind remote control according to principle described above and actual needs.
