Description
One, technical field: the utility model relates to a kind of roller blind device, especially relevant with electric rolling.
Two, background technology: roller blind device can be widely used in the various occasion needing covering and barrier.As the panel superheater etc. in the window of the walking machine such as lid, automobile, steamer in the window on house, object storing storehouse and top cover and hall, house thereof.At present instead of original manual for the operation of roller blind device is mostly existing motor-driven, be very easy to the use of people.But electric rolling device is also the same with other newborn product, has the process of a gradual perfection, the instability of performance and shorter application life, constrain the development of electric rolling widely.
Patent 201210154591.9 is products comparatively outstanding in current electric rolling industry.After particularly have employed comparatively simple first fastening devices of structure and the second fastening devices, the conduit with driving-chain is fixedly connected between guide rail and driver element firmly, ensure that the prolongation in the stable further of performance and application life.But this patent also has its deficiency: because this patent ignores a major issue in power transmission design, just have to reinforce two links of conduit, although certain effect can be obtained, the problem such as thoroughly cannot improve driving-chain wearing and tearing and transmission resistance is large.This is because be chaindriven with transmission between driver element and pull bar, and driving-chain is placed oneself in the midst of by the bending channel that conduit is formed, because driving-chain slides in bending passage with load, driving-chain certainly will be caused like this to strengthen in the wearing and tearing of bending part, cause the transport resistance of power to increase significantly, and the active force of the junction of conduit and driver element and conduit and guide rail is improved significantly.Although the first fastening devices and the second fastening devices can guarantee the working properly of this two junction, the energy consumption of motor cannot decline, and roller shutter motion is relatively heavy, and response is poor, and the wearing and tearing of driving-chain also cannot reduce, and application life is also than originally not growing how many.
Three, summary of the invention: the purpose of this utility model is to provide a kind of dependable performance, energy consumption is less, driving-chain wearing and tearing are less, the electric rolling device of longer service life.
In order to solve above-mentioned task, the utility model directly will be installed on guide rail by motor-driven travelling gear, the Flexible Transmission tooth bar (driving-chain) carrying out power transmission between pull bar and travelling gear is linearly moved, thus can the wearing and tearing of reducing friction resistance and Flexible Transmission tooth bar significantly.And the secondary direct-drive of the Chain conveyer of power transmission shaft that transmission efficiency is higher or chain sprocket composition between motor and travelling gear, can be adopted, significantly can reduce energy consumption like this, easily realize the conversion from winding position to operating position of roller shutter.
Obviously, from composition structure, travelling gear both can level be installed, also can vertically install, and the power transmission between travelling gear and motor, both can use power transmission shaft, the Chain conveyer that also can form with sprocket wheel chain is secondary, the kind of these changes is more, and all skilled person all can be made multiple, and therefore the utility model is no longer added this to describe.
Because travelling gear of the present utility model is directly installed on one end of guide rail, the Flexible Transmission tooth bar between travelling gear and pull bar is made to be a straight line, namely the power on travelling gear is that linear transmission is on pull bar, therefore the side pressure between Flexible Transmission tooth bar and guide rail very little (linear gear rack does not have side pressure to both sides in theory), frictional resistance is very little, and wear and tear also very little, the power consumption of drive motors also reduces thereupon significantly, performance can be more stable, and application life also can be longer.
Although Flexible Transmission tooth bar (hypothesis has the direction of pull bar for above here) section after travelling gear also does bending motion, but because the rear end of Flexible Transmission tooth bar does not have live load, therefore Flexible Transmission tooth bar is very little to the lateral pressure on the sidewall at turning, frictional resistance is also just very little, weares and teares also very little.
If allow Flexible Transmission tooth bar (driving-chain) turn in the loaded situation of band, turning is so not only needed to have higher fineness, and need good lubricating condition, so not only can increased care cost, if Long-Time Service, the gap between Flexible Transmission tooth bar and bend also can be caused to strengthen, and the response causing roller shutter to move declines, and the abrasive dust produced also can pollute roller shutter.
Due to the change of the transmission position of this travelling gear of the present utility model, really be a kind of very little change, from also not seeing there is great innovation inside on the surface, therefore effect wherein very easily ignore by the people in industry, if even there is people also to make the roller blind device with the utility model similar structures once in a while, if carefully do not go the advantage analyzed wherein, also can abandon conveniently and make other structure into, this is also the reason that electric rolling so far still has these problems in fact.
Although the two ends of conduit are fixed by two fastening devicess, also to can yet be regarded as a kind of method of dealing with problems, but the utility model is then solve this problem up hill and dale from another angle, thus make the extensive universal of electric rolling become possibility, therefore this change of the present utility model, its practical significance is very large.

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Five, detailed description of the invention:
Fig. 1 is the electric rolling device schematic diagram that travelling gear is arranged near the right end of guide rail, is an embodiment of the present utility model.For convenience of description, four frames are divided into by the framework of whole roller blind device to be described.That is: upper frame 11, underframe 12, left frame 13, correct frame 14; Two guide rails 1 are installed on upper frame 11 and underframe 12 respectively abreast, and make the distance between two guide rails, and can make with the cutting width error of roller shutter and adjust installation accordingly, the right-hand member of guide rail 1 is also connected with curved tooth bar sheath 2; (the right side that is depicted as in figure near the right end that travelling gear 3 is installed on guide rail 1, actually one end of curved tooth bar sheath is mounted in, the utility model has one end of tooth bar sheath with the representative of " near right end " printed words, below no longer repeat specification) position, and engage with the Flexible Transmission tooth bar 4 in guide rail 1; Flexible Transmission tooth bar 4 is installed on is combined in the chute 10 that forms by guide rail 1 and curved tooth bar sheath 2, and can slide in chute 10 relative to guide rail 1 and curved tooth bar sheath 2; Motor 15 is installed on correct frame 14, and and with driving member 6 connection for transmission between travelling gear 3, the driving member 6 in figure is power transmission shafts 7; One end of power transmission shaft 7 is connected with the output of motor, why the other end (wants active connection here with travelling gear 3 with active connection that spline 5 is done axially to twitch, mainly consider that the width between two guide rails needs to determine because of the cutting error of roller shutter, but also can connect without pattern chain, as long as travelling gear is done thicker also passable, after two guide rails are fixed, herein just can be motionless); Roller shutter 8 is installed between upper frame 11 and underframe 12, can relative to whole frame member, roller shutter 8 is reeled by piece of cloth and forms, the bead of its piece of cloth direction of extension is provided with pull bar 9, the two ends of pull bar 9 are connected with the Flexible Transmission tooth bar 4 in the chute 10 be arranged on two guide rails 1 respectively, and can together with Flexible Transmission tooth bar 4, the slide on guide rail 1, thus drive roller shutter to do the conversion of winding position and expanded position.
When motor 15 rotates, coupled power transmission shaft 7 also rotates, thus band nutating gear 3 rotates, the rotation of travelling gear 3, move in the chute 10 driving Flexible Transmission tooth bar 4 to form at guide rail 1 and curved tooth bar sheath 2, the kinetic-potential of Flexible Transmission tooth bar 4 must drive connected pull bar 9 to do translational motion along guide rail 1, the motion finally making roller shutter 8 follow pull bar 9 to roll or launch.
Be not difficult to find out in the transmission of above-mentioned roller blind device, this section of Flexible Transmission tooth bar 4 from travelling gear 3 to pull bar 9 is in line state, no matter Flexible Transmission tooth bar 4 is pushing drawing rods 9 drives roller shutter 8 to do to launch motion, still pull bar 9 is pulled to drive roller shutter 8 to roll motion, act on the direction of the power on Flexible Transmission tooth bar 4 always along the rectilinear direction at Flexible Transmission tooth bar 4 place, therefore the chute wall on Flexible Transmission tooth bar 4 pairs of place guide rails 1 does not almost have lateral pressure, obvious lateral pressure is little, the frictional force of Flexible Transmission tooth bar 4 pairs of chute 10 sidewalls is also little, and frictional force is little, energy consumption is also little, wear and tear also little.If allow Flexible Transmission tooth bar 4 by load transmission on bend band, then the direction of power changes because of bend, Flexible Transmission tooth bar 4 must apply pressure to the sidewall of chute 10, one could be obtained and change nyctitropic reaction force, therefore frictional force just rises significantly, therefore wearing and tearing also strengthen, and the energy consumption of motor 15 also strengthens.
Curved tooth bar sheath 2 in figure is bending, and chute 10 wherein is also bending in this position, and it is positioned at the right of travelling gear 3, and the Flexible Transmission tooth bar 4 in chute 10 is also bending motion.But because one section of Flexible Transmission tooth bar 4 on the right of travelling gear 3 does not have load, only have Flexible Transmission tooth bar 4 itself, therefore very little to the pressure of the bend sidewall of chute 10, frictional resistance is also just very little, weares and teares also very little.
Fig. 2 is power transmission shaft 7 and type of belt drive schematic diagram during travelling gear 3 place plane parallel.Here many a pair bevel gear transmissions 16, though this type of belt drive is more more complex than Fig. 1, but because bending Flexible Transmission tooth bar 3 just in time drops in the plane at travelling gear 3 place, the prolongation in the application life of travelling gear 3 pairs of Flexible Transmission tooth bars 4 of therefore this form installation is extremely beneficial.
Fig. 3 is the type of belt drive schematic diagram replacing transmission shaft driven with Chain conveyer.Driving member in the utility model, in fact can have many kinds, can be transmission shaft driven, also can be secondary 17 transmissions of Chain conveyer of sprocket wheel chain composition, can be also all gear connection for transmission etc. certainly, no longer too much describe here.In figure, for asking simple, motor 15 is vertically installed, but here conveniently figure look, also motor 15 has been signed in the behind of sprocket wheel, can increase the thickness of correct frame 14 like this, true motor 15 can tune when using come to use.
The transmission efficiency of Chain conveyer pair 17 is higher, is a kind of outstanding driving member, but the joint that shortcoming is centre connects more, and Long-Time Service has accumulated error, and therefore usual regulating wheel etc. are eliminated (not drawing in figure).
Fig. 4 is set up in the positive contraposition of Flexible Transmission tooth bar 4 back side and travelling gear 3 the type of belt drive schematic diagram installing pulley.Pulley (can certainly be gear or even another travelling gear) is installed at the back side of Flexible Transmission tooth bar 4 and the positive contraposition of travelling gear 3, mainly be to reduce wear further, the sliding friction become between Flexible Transmission tooth bar 4 and guide rail 1 is rolling friction, obvious Fig. 1 is also suitable for this installation, and just upper and lower two frameworks want thicker.This design, for large-scale roller blind device, has certain effect.
In addition, travelling gear 3 disclosed in the utility model be installed on guide rail 1 right end near, should be at right end actually.But along with of the present utility model open, make the travelling gear on roller shutter that part is in the industry similar, moved to both sides by the centre position of original correct frame 14 and enter the sweep position of curved tooth bar sheath 2, be difficult to make with the utility model define, because in the bend place transmission of curved tooth bar sheath 2, also more far better at the intermediate transmission of correct frame 13 than present, therefore also protection domain of the present utility model should be belonged to, namely the utility model is for the description of " near right end ", include the sweep of this curved tooth bar sheath 2, the power of Flexible Transmission tooth bar 4 is carried simultaneously, also the power on motor 15 is delivered to pull bar 9 with can only being described as " be almost in line shape ".
