Abstract

The utility model relates to an automatic device which can control the opening and the closing of a curtain. A motor, a pulley and a steel cable are arranged in a curtain box; the motor is connected with the pulley via a transmission belt; the curtain is sheathed on the steel cable via a sliding ring; an infrared receiver is connected with the motor via a wire; a control circuit comprising an infrared receiving and amplifying circuit, an anti-jamming circuit, a switch circuit, a monostable circuit, a pulse counting circuit and a circuit for the reverse and positive rotation of the motor is arranged in the infrared receiver. The utility model which has simple structure and convenient operation can take the universal remote controller of televisions or videoplayers as a transmitting apparatus to control the opening and the closing of the curtain.

Description

The infra-red remote control window curtain driving mechanism

The utility model relates to a kind of device that can open and close automatically curtain.

Present known curtain is made up of the curtain that pelmet, pulley, static line, rope and upside are fixed with slip ring, curtain socket-connects by slip ring and static line, one end of rope is walked around the interior pulley of pelmet and a side of curtain is joined, and the shortcoming of its existence is that the opening and closing of curtain need be finished by the pulling rope.

The purpose of this utility model provides a kind of infra-red remote control window curtain driving mechanism that can open and close automatically curtain.

The purpose of this utility model is achieved in that the two ends in pelmet are fixed with pulley yoke respectively, two pulleys respectively with pulley yoke on bearing pin join, and two pulleys are joined by driving-belt, the two ends of steel wire rope respectively with pelmet in the steel wire rope fixed mount fix, the pulley coaxle transmission of the pulley of one end and one side, and join by the belt pulley on driving-belt and the motor, the slip ring and the steel wire rope that fix with the curtain upside socket-connect, infrared receiver by attaching plug is housed electric wire and the motor in the pelmet join, in infrared receiver, be provided with by ic chip ₁, infrared receiver tube D, resistance R ₁, R ₂, R ₃, variable resistor W, capacitor C ₁, C ₂And C ₃The infrared ray that constitutes that joins receives amplifying circuit, by capacitor C ₄The anti-jamming circuit that constitutes is by triode BG ₁, resistance R ₄The on-off circuit that constitutes is by ic chip ₂, resistance R ₅, capacitor C ₅And C ₆The monostable circuit that constitutes is by ic chip ₃The pulse-scaling circuit that constitutes is by triode BG ₂, BG ₃, BG ₄, BG ₄The motor that constitutes with motor M is shifting circuit anyway.

Owing to adopt such scheme, can utilize the general remote controller of television set or enlarger as emitter, so as to realizing opening and closing automatically of curtain, simple in structure, highly sensitive, easy to use.

Below by drawings and Examples the utility model is described further.

Fig. 1 is a structure chart of the present utility model.

Fig. 2 is circuit theory diagrams of the present utility model.

Among the figure 1, motor 2, pelmet 3, pulley 4, steel wire rope fixed mount 5, steel wire rope 6, slip ring 7, driving-belt 8, curtain 9, pulley yoke 10, electric wire 11, attaching plug 12, infrared receiver 13, infrared receiver tube

In embodiment illustrated in figures 1 and 2, two pulley yokes (9) are individually fixed in the two ends of pelmet (2), be hinged with pulley (3) by bearing pin in the pulley yoke (9), two pulleys (3) are connected by driving-belt (7), the two ends of steel wire rope (5) respectively with pelmet (2) in steel wire rope fixed mount (4) fix, the pulley coaxle transmission of pulley of one end (3) and one side, and be connected with belt pulley on the motor (1) by driving-belt (7), curtain (8) socket-connects by the slip ring (6) and the steel wire rope (5) of its upside, infrared receiver (12) is connected with the interior motor M (1) of pelmet (2) by the electric wire (10) that attaching plug (11) are housed, in infrared receiver tube D (13), resistance R ₁, R ₂, R ₃, variable resistor W, capacitor C ₁, C ₂And C ₃The infrared ray that constitutes that joins receives amplifying circuit, by capacitor C ₄The anti-jamming circuit that constitutes is by triode BG ₁And resistance R ₄The on-off circuit that joins and constitute is by ic chip ₃, resistance R ₅, capacitor C ₅And C ₆The monostable circuit of joining and constituting is by ic chip ₃The pulse-scaling circuit that constitutes is by triode BG ₂, BG ₃, BG ₄, BG ₄With motor M (1) motor that the constitutes shifting circuit anyway that joins.This device must and the use that matches of television set or the general remote controller of enlarger, with as emitter, the operation principle of following each circuit of division, at first be that infrared ray receives amplifying circuit, after infrared ray receiving tube D (13) receives infrared signal, it can convert infrared signal to the signal of telecommunication of same frequency, and is input to ic chip ₁On the infrared ray amplifying circuit for core, when this circuit is in static state, ic chip ₁7 pin be high level, triode BG ₁, conducting, make the signal of telecommunication be input to monostable circuit, the function of monostable circuit is, when whenever pressing the button of a remote controller, just launches several pulses, monostable circuit is just overturn after being input to first pulse, i.e. the output ic chip ₂3 pin be converted into high level after the upset by the low level of normality, high level is kept after a period of time (by resistance R ₅And capacitor C ₅The length of decision time) automatically reply former low level state again, promptly every input set of pulses, monostable circuit is just only exported a pulse and is flowed to by ic chip ₃The pulse-scaling circuit that constitutes, when pulse-scaling circuit is in static state, its output P ₀For high level is called one state, P ₁, P ₂, P ₃And P ₄Output is " 0 " state, when first pulse of input, and P ₁Be one state, P ₀, P ₂, P ₃And P ₄Be " 0 " state, when input second, third, during the 4th pulse, P ₂, P ₃, P ₄Be one state, all the other outputs are " 0 " state, because of P ₄Join with reset terminal, work as P ₄Automatically reset during for high level, i.e. P ₄During for high level, P ₀Reply and to be one state, the circulation that so goes round and begins again, when motor shifting circuit anyway, motor M (1) does not rotate when being in static state, works as ic chip ₃P ₁When being in one state, motor M (1) begins to rotate, and works as ic chip ₃P ₂During for high level, motor M (1) stops operating, and works as ic chip ₃P ₃Ic chip is worked as in motor M (1) counter-rotating during for high level ₃P ₄During for high level, motor M (1) stops operating, and when infrared signal of the every emission of remote controller, its infrared signal is received amplifying circuit by the infrared ray that is made of infrared receiver tube (13) and receives, export to pulse-scaling circuit, ic chip by pulse of monostable circuit output ₃Output control motor M (1) shifting circuit anyway respectively, just be in the duty of changeing, stop, reversing, stopping respectively with control motor M (1), thereby realize making curtain accomplish to open, stop, closing, stop one of four states.
