Abstract

The utility model discloses a large-span automatically steering type electric machine for opening and closing curtain which comprises a curtain rail (3) with power supply, a rolling wheel and a power-driven device. The utility model is characterized in that the rolling wheel (5), an electric machine (11), a speed reducing mechanism (9) and a spring copper sheet (12) which contacts with the rail are arranged on a bearing plate, wherein, the spring copper sheet forms circuit loop with a conduct electricity rail through the electric machine. The utility model has the advantages of easy installation, no noise, large-span of the spring, etc. The rail can be arranged on one side and top and fixed by multiple points, and the utility model can automatically turn.

Description

Large-span automatic steering type electric machine for opening and closing curtain

The utility model is a kind of automatic steering-type electric controller for curtain of large span that is suitable for public building and residential houses.

At present, especially the electric controller for curtain kind is a lot of for window curtain driving mechanism, but fails to solve in the large span of window curtain driving mechanism and the problem that turns to automatically always.

The purpose of this utility model is: a kind of large span electric controller for curtain that can turn to automatically is provided.

The utility model by window curtain driving mechanism track (3), and the roller and the power-jdriven gear that roll thereon form.Characteristics are to be fixed with power roller (5), motor (11), reducing gear (9) and contact spring copper sheet (12) on the bearing plate (7), wherein motor (11), with the copper sheet (12) and strip conductor (3) the built-up circuit loop of motor (11) conducting.Motor and copper sheet (12) conducting can be passed through motor power-supply wire.Two strip conductors and middle insulating fixing piece (2) be linked to be "

" type, also available insulating materials make " " type track both sides are equipped with two bare power lines respectively and form.After the track energising, machine operation, the cog belt that drives reducing gear rotates, and makes power wheel (5) promote driven pulley (13) rolling, thereby realizes the keying of curtain.Can turn to automatically along track in order to solve the roller that upward rolls at track (3), adopt the way that changes two side wheels and interorbital frictional force, as: it is poor in the corner two siding tracks to have been dressed up certain height; Or two side wheel make with different materials, as a side rubber wheel, a side is a plastic wheel; Also can adopt the way of driven wheel, promptly a side wheel and wheel shaft are fixed, and another side wheel is enclosed within on the wheel shaft by axle sleeve; Or the linear velocity of change two-wheeled, as a side bull wheel, a side steamboat.In addition, the two ends of band curtain tieback working of plastics (15) are smooth circular-arc, in order to turning to of driven pulley (13).On the position of intersecting point of the axial line of roller and center of gravity line, also pull rope can be set.The utility model can directly be installed on the end face in room by fixture, also can adorn side plate (1), is fixed on the side walls.But its multiple spot is installed and fixing characteristics make window curtain driving mechanism easy for installation, and it is big to decorate span, and when having guaranteed to be used for large span and installing, track (3) can not be out of shape because of the weight of deadweight or curtain.Power supply by switch directly and the strip conductor conducting, various ways such as the optional usefulness of gauge tap is electronic, infra-red remote control, acoustic control, light-operated or wireless remotecontrol.

Superiority of the present utility model is: the decoration span is big, can turn to automatically, and noiselessness, easy for installation.Be illustrated below by accompanying drawing.

Accompanying drawing 1, the side view of the electric controller for curtain of charged actuation mechanism.

Accompanying drawing 2, driven pulley part vertical view.

Accompanying drawing 3, a kind of circuit theory diagrams of embodiment.

As Fig. 1, strip conductor (3) is made with metal material, connects with insulating fixing piece (2), is fixed on the side plate (1) by screw (4).Fixture (2) and side plate (1) can require to fix arbitrarily according to decorating.Be fixed with motor (11), reducing gear (9), spring copper sheet (12) and power roller (5) on the bearing plate (7), be covered with the plastic shell (10) of a band curtain tieback (8) in bearing plate (7) outside, motor (11) and reducing gear (9) are closed.Reducing gear (9) is two groups of cog belts, and noiseless advantage is arranged, and also can form with other deceleration device.As accompanying drawing 2, the working of plastics (15) of band curtain tieback is housed on the wheel shaft (14) of driven pulley (13), working of plastics (15) two ends are smooth circular-arc.Under the driving of power roller (5), can finish rolling smoothly, comprise automatically turning to, turn to as 135 °, or circular arc turn to.Electronic keying circuit theory of the present utility model, visual span size, watt level, the control curtain number of plies what and decide, present embodiment is with the dc low-voltage motor, it is example that single press button is controlled the individual layer curtain, as shown in Figure 3, finish the rotating of motor by switch control.Work as K ₁, K ₁' after closing, for just, for negative, work as K below above the motor ₂, K ₂' after closing,, for negative, so just formed the rotating of motor above below for just, and when press button during in inactive state, transformer is disconnected any power source, is not with no-load current, has guaranteed the service life and the safety coefficient of transformer.In switch control, can adopt infra-red remote control, light-operated, acoustic control or wireless remotecontrol etc.
