Description

A kind of Motorized blind system

Technical field

The present invention relates to a kind of Motorized blind system, specifically be a kind of be the Motorized blind system of power with alternating current motor or d.c. motor.

Background technology

Traditional Motorized blind system has the following disadvantages:

1. the roller blind system of most Motorized blinds requires motor and support directly to be installed on ceiling or wall, apparatus and method by the labyrinth that for the purpose of safety, designs, the pipe of an embedded motor is installed on support, and a termination of pipe is gone into the motor installation end, and the other end then is plugged with the tail plug.Such system is owing in the parallelism of motor and tail plug support be positioned with very accurate requirement, add its complicated structure, thereby not only be not easy to the installation and removal of system, and structure and device that should complexity have also taken a large amount of spaces.This structure also causes bigger slit between roller shutter and the wall, thereby causes having too much light to enter and the decline of privacy degree.

2. simultaneously, the electric wire of motor can only extend from installation end usually, thus determine curtain volume this just require to confirm that feeder ear or control end are on the right or on the left side; Otherwise just require circuit from one end to the other side to extend, yet this will allow outward appearance seem ugly.Make mistakes if in a single day this system installs, or reinstall cord, or the system that reinstalls changes the position of motor.

3. existing electric rolling control system requires to connect one with one on screw motor electric wire and power circuit is connected on its terminal.This just causes installing very takes time, and also causes because of control box is oversize and can't normally hide, unless be contained in the false ceiling the inside.And control box is contained in false ceiling, if ceiling is not knocked open, then can't touch controller, and also just can't keep in repair.And controller electronic circuit often is easier worse than motor.

4. the pipe of electric rolling all aims at one type cord and manufactures and designs.The system of a type can not be applicable to another kind.This has also caused when motor system being replaced manual roller shutter install very difficult.And unique solution is fixed to curtain above the pipe with adhesive tape exactly.And this is insecure.Simultaneously, install and fix in the mode at the existing of majority, adhesive tape is the edge that is fixed to curtain with stapler, slides into the groove of pipe then from the side.This also just causes all removing if not whole system, and cord just can't remove cleaning.

5. the accessory of electric rolling different designs, such as on market now, most manual roller blind systems requires to tailor the pipe and the upper beam of different length.This has also just caused the inefficiencies of making and producing.

6. owing to the 4th problem above-mentioned (must assemble advancing slip inlet pipe fully) and the 5th problem, the manufacturing of roller blind system must be finished in factory.And this also causes when project site is installed, the dirty environment cord of can making dirty.And supplier must arrive on-the-spot size of measuring each window, and knows the position of generating end, and then produces blind system at this point.In case the size of measuring is wrong or generating end location is wrong, then whole system must be sent factory back to and adjusted.

7. all existing roller blind systems all are only to design for roller shutter.Even stay cord can be installed in the cloth that draws roman shade on the pipe, sign indicating number is installed but a magic strap that adds must be installed separately.This has also just caused the user not replace between roller shutter and roman shade.Simultaneously, the winder of rolling rope all is embedded into by the end of pipe usually.This just requires end support and tail plug to take apart, then winder is inserted the tram, end support and tail plug is fixed on the pipe at last again.

8. the top of Duo Shuo electric rolling system and the automatic spacing of bottom are provided with by switch, can pushing by chain mechanism or direct electron button.Switch generally is positioned on the motor installation end, and this also has bigger space to make light can penetrate into the room with regard to having caused.

9. existing is to be linked together to install by an intermediate support to form by the biplate cloth of a motor driving or the roller blind system of three cloth.And this intermediate support is an accurate structure that the integration of tail plug is respectively arranged at the right and left.The tail plug on both sides must be installed in position separately simultaneously, and this just causes bigger space between window and the curtain.Also improved installation cost.Though contain spring lever in the design of some such support, thereby can reduce the space between window and the curtain.Yet the accuracy of support installation site requires but very strict, otherwise is difficult to manage insertion, simultaneously, also is not easy to pipe is removed.

10. as above-mentioned said, all existing electric rolling systems must pass through mechanical switch, and electronic switch or remote control procedure are provided with the spacing of upper end and bottom.All these is time-consuming, and if be provided with and make mistakes then can influence the reliability of system.Especially when the excess revolutions of roller shutter cloth, then may be that it is impaired.

The specific embodiment

As shown in Figure 1, 2, the roller blind system 10 of Motorized blind, it comprises roller shutter pipe 1, upper beam 2, motor frame 3, tail plug support 4, motor 5, motor 5 is contained in the roller shutter pipe 1, its motor installation head 5a is exposed to outer and is connected with motor frame 3, does not perhaps fasten with it by the hole above the motor frame 3 (have among the figure and show).Electric rolling system 10 also comprises tail plug 6, and tail plug 6 is plugged in the other end of roller shutter pipe 1, and outside its trailing edge 6a was exposed to, put the beams in place 2 an end and motor frame 3 were fixed by screw I 3b, and the other end and tail plug support 4 are fixed together by screw I I4a.Motor installation head 5a is provided with two mechanical stop buttons, and (a mechanical stop button is used to limit the extreme higher position that roller shutter cloth is rolled, the extreme lower position that another mechanical stop button is used to limit roller shutter cloth when putting down has only one demonstration is arranged in the drawings) or an electronic limit device button.Motor 5 is as can also placing outside it with the 1 suitable combination of roller shutter pipe.

As shown in Figure 2, tail plug 6 is installed on the tail plug support 4 by bearing 7, at the end of tail plug 6 towards tail plug support 4, there is an axle 6b from the cylindrical groove 6c of tail plug 6 ends, to stretch out along the axis, the slightly larger in diameter of cylindrical groove 6c is in the external diameter of bearing 7, and axle 6b passes the interior annular distance 7a of bearing 7 and supports rotation by it.Screw I II4b passes tail plug support 4, be fixed on again on bearing 7 corresponding two screw 7b, both are fixed tightly in together, the thickness of bearing 7 is bigger than the degree of depth of cylindrical groove 6c, so that be given in 6 spaces of tail plug support 4 inboards and tail plug, can not be ground to tail plug support 4 inboards when making 6 rotations of tail plug; In addition, tail plug support 4 is inwardly bent into, and it bends the gap length that trailing edge 6a thickness that into width equals tail plug 6 adds 6 of tail plug support 4 inboards and tail plugs.Design with this, just can make and place it in directly when a roller blind system that has installed carries out length adjustment that a cutter just can downcut on the cutting knife, cut roller shutter pipe 1 more respectively and put the beams in place 2 and needn't pull down earlier, as shown in Figures 2 and 3, during installation, being installed, sign indicating number 8 usefulness screw I V8a are installed on ceiling or the wall earlier, and then the upper beam 2 of roller blind system 10 snapped in install in the sign indicating number 8, clearly, such structure, tool free also can be pulled down roller blind system 10 easily.

Traditional electric rolling system architecture need be positioned on motor frame and tail plug support earlier on ceiling or the wall, and then an effective the whole bag of tricks of roller shutter and a pair part are installed on motor frame and the tail plug support, and the present invention only needs several screws installation sign indicating number to get final product.In addition; this structure is with screw motor frame and tail plug support to be fixed on the upper beam; this system can significantly reduce the gap width on window limit; reduce the light rate and improve secret protection, and the very big space thickness that the motor frame of traditional electric rolling system and tail plug support cause because of the structure of complexity.

As shown in figs. 1 and 3, roller blind system 10 also is furnished with the controller 9 of a control motor 5, and it comprises shell 9a, and power line 9b has the motor control line 9c and the socket 9b ' of plug, and digital control is provided with button 9d under wireless or the infrared signal remote control situation.About the circuit of remote controller 9, this paper does not do detailed explanation, because this controller is the standard circuit that is used for direct current or alternating current motor, as long as the skilled people of specialty is easy to operation.Power line 9b comprises 3 electric wires, i.e. ground wire, and live wire and zero line are connected to power end (power supply) by the connector that can insert or traditional socket (do not have among the figure and show).Ground wire also is connected to system body, to guarantee safety.Under the direct current situation, controller 9 must have a power supply adaptor, perhaps is connected to external direct current supply (comprising external adapter or chargeable battery).Be connected to external direct current supply if adopt, power line 9b must be an AC line.Motor control line 9c is extended out by motor 5, and is connected on the plug of itself and socket 9c ' coupling.Feasible installation of the connection of plug and socket and disconnection are faster simpler.Under the direct-current electric motor situation, line 9c has 2 electric wires, and promptly the live wire and the ground wire of 12 volts of the DC voltages of reverse or 24 volts also can make the motor with positive and negative running by 3 electric wires.And under the situation of alternating current motor, generally all be 4 electric wires, 1 zero line, 1 ground wire and 2 live wires are controlled forward and reverse running.

Control is provided with button 9d and stretches out from shell 9a and 2 the boring of putting the beams in place, and is convenient to allow user one touch the button and promptly can obtains remote control transmission signal.As shown in fig. 1, motor 5 is mounted in the left-hand side, one side motor control line 9c be from motor 5 by any top of 2 of putting the beams in place that reaches, the left and right sides of motor frame 3, extend to 2 the inside of putting the beams in place then and be connected with controller 9 by socket 9c '.Any one side, power line 9b slave controller 9 left and right sides power end (exchange or direct current) that extends out.As shown in Figure 3, the sidewall and the controller housing 9a of upper beam 2 have the space.Line 9b can extend to right-hand side through space thus.Certainly, enough spaces are arranged between controller 9 and ceiling, line 9b can pass right-hand side.Had this to be provided with, need not change the position or the swivelling pipe 1 of motor 5, system 10 need not expose that mixed and disorderly electric wire can limit or right-hand side be connected to power supply leftward easily.Because of the direction of roller shutter pipe with same orientation and rotation fixes, so the installation direction of roller shutter cloth is not subjected to the influence of position of source or control signal line position.

When control device in motor the inside, just have only a power line therefrom to extend out.Therefore, so long as the electric wire long enough, power line circuit in a large number is exposed to outer and enters upper beam.Therefore the fixing direction of cord has no association with the power end position.DC power source adapter is positioned in and puts the beams in place 2 if controller is embedded in AC line motor the inside, and the motor wire of coming out from motor is connected to puts the beams in place above 2 on the power supply adaptor.Power supply adaptor has its AC power cord, receives the AC power end.

Controller can be installed in the switch enclosure that has rechargeable battery that is arranged on the wall, or is installed in one independently in the shell shown in dotted lines in Figure 1.In this case, the motor control line connects by the direct-current electric motor control circuit (tape relay control) of standard or by a revolution switch of controlling the AC/DC switching of power supply supply, and main power source (direct current) line connects battery.Battery is located at knock-down battery case, and rechargeable battery can be taken out in the battery case and be put into cradle and charge.

Another feature of this invention is that it can be provided with button with electronics location and moves on in the controller 9 from motor head 5a.Its reset button 9e is similar to button 9d among Fig. 3.The connecting line of button 9e (do not have among the figure and show) extends out from motor.Under this design, the shared space of motor head 5a becomes littler.Therefore roller shutter cloth can be made into and more roomyly further dwindle the space, so that sunlight still less can penetrate into, better crypticity is arranged also.If spacing the setting can be finished by the remote controller transmission procedure in addition certainly, the space also can reduce so, though program all is more loaded down with trivial details to setter and user.

As shown in Figure 4, the tube wall of roller shutter pipe 1 is provided with magic strap holddown groove 11, magic strap is to be made of the two parts that overlap, a part is depressed by flange 11b and is embedded in the holddown groove 11 or available double faced adhesive tape is fixed to this on 11a of holddown groove bottom surface, another part must be sewn on the upper end-face edge of roller shutter cloth, and vice versa.Magic strap has been arranged, and when roller shutter need clean, its mounting or dismounting were very convenient.

As shown in Figure 5, the tube wall of roller shutter pipe 1 is provided with a cord clamping holddown groove 12a, magic strap holddown groove 11, a cord clamping holddown groove 12a, magic strap holddown groove 11 are located at the both sides of the tube wall of roller shutter pipe 1 respectively, be plugged with a cord clamping 12b who is coupled with it in the described cord clamping holddown groove 12a, a cord clamping 12b is come to fix with an end of roller shutter cloth by staple 12c or other modes.On tube wall a cord clamping holddown groove 12a, magic strap holddown groove 11, provide two kinds of different mounting meanss to the user.

Take electric rolling 40 do example explain top and bottom spacing be how to operate or install make can be automatically at the top and the bottom require the position autostop, and need not field adjustable.Explain at first how the bottom automatic spacing reaches.

Pass the roller shutter pipe 1 of motor 5 among Figure 14, and the position of roller shutter pipe among Fig. 8 all is that to be arranged on this position in advance spacing as the bottom, the mode of motor setting can be mechanical interlocked limit switch, electronic inductor or by the program mode (PM) of remote controller control.Though the position of pipe is identical, the motor that connects the roller shutter pipe is that the position from the cord bottommost begins to roll, and motor 5 has rolled and rolled a lot of layers of circle cord.This just means that also the roller shutter pipe can not turn clockwise again, can only be rotated counterclockwise, and this is the position that roller shutter is closed fully.We suppose that the requirement of roller shutter highly is T, and the distance of the intermediate point of ceiling and roller shutter pipe 1 is h, and the diameter of roller shutter pipe 1 is

, the effective thickness of bottom bar is B (is exactly in fact the vertical thickness of bottom bar deduct cord be embedded in length in the bar).When the roller blind system with Fig. 8 and cord fixed form shown in Figure 14 is provided, should come the cutting cord according to following formula:

If the sort of in the upper grooves among image pattern 8 and Figure 14 then taked following formula:

The spacing system that configures in this prior bottom, the size when being exactly complete opening according to above-mentioned formula cutting and fixing cord.Utilize this method, can save the trouble of the spacing setting of a lot of adjustment, especially the bottom is spacing.Therefore the time of installing can be saved much, and does not also have so high to the technical requirements of installation personnel.

Secondly, we will explain top stopping means 44 is how to accomplish work that the top is spacing.When relay 103 cut out under the situation of signal demonstration " opening ", motor driving roller shutter pipe 1 rotates in a counter-clockwise direction rolled cord 45, and pull-up bottom bar 46.Hinge handle 44c design long enough allowing the bigger bottom bar 46 of diameter can touch it, and it is upwards pressed, to allow cord 45 pass mobile and the hinge handle also is reserved with enough spaces.When bottom bar 46 is shifted to hinge handle 44c, the former can upwards push hinge handle 44c, is then depressed to trigger button 44b ' and comes the normal closed valve of trigger switch 44b to open.Therefore motor 5 power supplies are cut off, and motor 5 is stopped.When relay is closed, then motor 5 beginnings in a clockwise direction rotation drive roller shutter pipe 1 and roll out cord 45, and put down bottom bar 46.Therefore bottom bar 46 detaches hinge handle 44c, and trigger button 44b ' is released, and the normal closed valve of switch 44b is closed.Cord 45 and bottom bar 46 will move down.So electronic roller blind system 40 reaches full-automatic automatic spacing (need not the people regulates).

The operation of electronic roman shade system 50 that connects the top stopping means is the same with above-mentioned roller blind system 40.Unique is not both the hinge handle by the first upwards pushing of movement weight rod 56.As the maximum size of complete expansion cloth when wanting cord all to be put down, stay cord must be tied up on last movement weight rod 56, and is stretched to the longest at this moment.

According to foregoing description, we have realized each purpose of this invention, main is exactly realized one " both inserted and promptly used " farthest near household electric appliances, as the Motorized blind system of the product of fan sample.It has been reduced make workload and the cost of installing, also simplified pre-sales and after-sale service.Be that a real example is explained method and the program that such system is installed of how producing below.

Electric rolling

The width that customizes one or minority roller shutter is applied to a large amount of productions, such as 1.5 meters, and 2 meters, 2.5 meters

As the described mode of above-mentioned Fig. 1-3, motor, controller and distribution therebetween, pipe is put the beams in place, the tail plug frame that motor frame, tape spool hold, the tail plug assembles up.

Set among the spacing position that makes pipe of motor and Fig. 8 and Figure 14 equally, and guarantee that motor can be with under the yardage roll, go up the number of turns of system's maximum or other and the enough number of turns of most of windows correspondences but can twist in pipe

Measure the width of the curtain of demand, and come clip system length (upper beam and pipe are once cut together) according to this size, and fixed support

According to the system of Fig. 1 and foregoing description, then system is sandwiched sign indicating number is installed, power line is connected on controller or the motor

Come the broadband of cutting cord according to the length of pipe (allow 2-3mm short poor), highly then be by the height of window or the overall height of requirement+begin volume grow (

)-system height h-bottom bar effective thickness B directly is connected to cord on the pipe then, to guarantee forming whole requirement height automatically.

According to Figure 14-16, the cord that moves up triggers an external switch up to bottom bar, stops motor.

Electronic Rome roller shutter

Its program substantially is similar to roller shutter, but cord cut out and stay cord fixing more convenient because the height of cord and width are exactly height and width that requirement window face covers, and stay cord is relatively flexibly and installation easily.

Make a general survey of above this invention explanation and explanation, clearly, this invents some and improves and change and can not deviate from this scope of invention and marrow.
