Abstract
The utility model relates to an electric curtain frame which can automatically open and close the curtain in low noise. A positive and reverse rotation motor is installed in a usual curtain cover. A belt pulley is driven to rotate by the speed reduction of a worm gear and a worm. The fixed block of a belt drives the curtain hung on an idler wheel to move on a guide rail. The utility model uses a travel switch as an invertible inching which can stop automatically to start a mixed control circuit. When the motor rotates, the idler wheel rolls on the guide rail in low speed. The curtain is opened and closed in silence and automatically stops moving when the curtain reaches to a prescribed position.
Description
The present invention relates to be used in the daily necessities curtain rod arm of folding curtain.
Known electrically driven curtain frame drives curtain with linear electric motors and carries out folding.All tiebacks and whole motor secondary are all slided on the electric motor primary of double as guide rail, terminal at stroke stops motor secondary to front slide by block, higher because of the speed of service of linear electric motors, the noise of generation is bigger so whole device is in operation.
It is very little to the objective of the invention is to design a kind of operation noise, and can control the curtain rod arm of curtain open/close automatically.
Based on Fig. 1, example shown in Figure 2, structure of the present invention is described as follows:
Noiseless automatic curtain frame shown in Figure 1, motor (1) drive driving wheel (4) rotation after deceleration device (11) slows down, belt (6) is installed on driving wheel (4) and the driven pulley (5), and driving wheel (4) is identical with the diameter of driven pulley (5).Deceleration device among the present invention (11) can be worm gear (2), worm screw (3) reducing gear, also can be gear reduction etc.
As shown in Figure 2, belt (6) relatively both sides respectively has a fixed block (7) to be fixed in the above, and the strip length between two fixed blocks equals 1/2nd total belt lengths.Methods such as the available bolt of fixed block (7), hasp are fastened on the belt (6).Connect with flexible articles such as rigid objects such as pole or ropes between fixed block (7) and the active roller (8), when making fixed block (7) move left and right, active roller (8) is move left and right thereupon also.
Guide rail (10) is installed in the below of band (6), and near the position of two belt wheel center lines, its cross section can be rail shape arbitrarily, can be that composite is made.The shape and the guide rail cross sectional shape of active roller (8) and roller follower (9) match.As the guide rail cross section is semicircle, and the shape of that roller (8), (9) is exactly be recessed into semicircle in the centre cylindrical.Guide rail (10) can be only with one long, at this moment curtain with regard to folk prescription to unlatching.Also can be with some the use that combines of two weak points, curtain just can be divided into two width of cloth like this, has opened relatively or in opposite directions.
Active roller (8) and roller follower (9) are installed on the guide rail (10), and a guide rail (10) is only with an active roller (8) and some roller followers (9).The shape of active roller (8) is similar to roller follower (9), and need not put on the axle (A) that just is active roller (8) has pole or rope etc. connecting with fixed block (7), and does not have this connection on the axle (A) of roller follower (9).As shown in Figure 3, all be equipped with push rod (B) and hook (C) on the axle (A) of active roller (8) and roller follower (9).Axle (A), the position of push rod (B) and hook (C) is orthogonal.Hook (C) is used for hanging curtain.The effect of push rod (B) is: when curtain is opened, the push rod (B) of a back roller (8), (9) pushes away on the axle (A) of previous roller (8), (9), roller is only gone up at guide rail (10) rolled, help further reducing noise and reduce the resistance of motion.
Because of the unidirectional stroke of fixed block (7) at most can not be above 1/2nd band transmission centre-to-centre spacing, so must there be travel switch to control its stroke.Electrical structure as shown in Figure 4, motor is to turn to reversible micromachine.Control section is made up of travel switch (ZXK), (FXK) and relay (ZC), (FC) etc., is reversible crawl, running, and travel switch is made self-braking control circuit structure.In Fig. 4, crawl and interlock are same (ZAN) or (FAN) button, are controlled by switch (K2).(K1) be power switch.
The present invention is because of adopting the reducing gear of worm gear (2), this low noise of worm screw (3), big retarding ratio, not only make deceleration device (11) volume-diminished, and make roller (8), (9) on guide rail (10), do the rolling of low speed, so reduce significantly than known electrically driven curtain frame operation noise.Again because of adopting full-automatic control circuit, make compact conformation of the present invention, multiple functional.The present invention simultaneously still has long advantage of life-span.
Following accompanying drawing has been described one embodiment of the present of invention.
Fig. 1 represents front view of the present invention, and Fig. 2 represents vertical view of the present invention, and Fig. 3, Fig. 5 represent the front view and the side view of roller, and Fig. 4 is a circuit diagram of the present invention.
In order to bring into play advantage of the present invention to greatest extent, in Fig. 1, worm gear (2), belt wheel (4), (5), roller (8), (9) and guide rail (10) etc. can select for use suitable engineering plastics to make, so that it can reduce weight and eliminate noise, connect apart from can not be too far away between fixed block (7) and the active roller (8), do not reach maximum required stroke to avoid the curtain stroke.Belt (6) is generally selected zero type V-belt for use, with weight reduction and reduced volume.Can lean on fixed block (7) to form, so that the window of the pretension of control band transmission and adaptation any width with two connections.
Above structure has been arranged, rotatablely moving of motor (1) just is transformed into the rectilinear motion that guide rail (10) is gone up roller (8), (9), installs travel switch (ZXK), (FXK) again at guide rail (10) two ends to control the stroke and the direction of motion of roller (8), (9).When needs folding curtain, closed (K2) clicks (ZNA) or (FNA) button, and curtain is standard-sized sheet or close entirely automatically.When open (K2) button (ZXK), (FXK) become inching button, the folding degree of curtain is control just arbitrarily.
