[specific embodiment]
As depicted in figs. 1 and 2, a kind of roller blind device of constant tension, comprise the motor 2 that is installed on the electric machine support 1, the central axis 3 and parallel second hollow section 402 that be enclosed within central axis 3 and machine shaft outside fixedly connected with machine shaft, the end that described central axis 3 is fixedlyed connected with machine shaft is the central axis drive end, its other end is the central axis driven end, also comprise with machine shaft coaxial, and apply the torsion spring constant force device of a constant force on second hollow section 402 all the time, the direction of rotation of second hollow section 402 when the direction of this constant force and roller shutter launch, described torsion spring constant force device are arranged in the space between central axis 3 and the machine shaft and second hollow section 402.
Described torsion spring constant force device comprises first hollow section 401, first moving runner 501, second moving runner 502, the 3rd moving runner 503 and torsion spring, described first hollow section 401 is enclosed within central axis 3 outsides, the one end is fixed on the central axis 3 of motor driven end, the unsettled drive end that approaches central axis 3 of its other end; Described first moving runner 501 and second moving runner 502 are all fixed by bearing and central axis 3, can be separately positioned on the central axis 3 of motor driven end and drive end around central axis 3 rotations; Described torsion spring 6 is enclosed within first hollow section, 401 outsides, and the one end is fixed on first hollow section 401 of motor driven end, and its other end is fixed on second moving runner 502; Described the 3rd moving runner 503 is fixed near on the machine shaft at electric machine support 1 place; Be concavo-convex alternate shape around described first moving runner 501, second moving runner 502 and the 3rd moving runner 503, the shape of the inwall around second hollow section 402 is complementary with it, thereby second hollow section 402 can be fixed on first moving runner 501, second moving runner 502 and the 3rd moving runner 503 in socket.Because the two ends of torsion spring 6 are separately fixed on first hollow section 401 and second moving runner 502, so the twisting resistance of torsion spring 6 just acts between first hollow section 401 and second moving runner 502; Because first hollow section 401 is fixing with central axis 3,, this twisting resistance acts between the central axis 3 and second moving runner 502 again so being equal to; Again because second hollow section 402 is socketed on first moving runner 501, second moving runner 502 and the 3rd moving runner 503, act between the central axis 3 and second hollow section 402 so this twisting resistance further is equal to, this twisting resistance that is act on central axis 3 and the 3rd moving runner 503 between; When the driving force of motor acts on the central axis, the 3rd moving runner 503 is along with the rotation of central axis 3 is rotated, so torsion spring can keep constant force in the motor rotating process, but when the twisting resistance of torsion spring 6 acted on the 3rd moving runner 503, the 3rd moving runner 503 can rotate to centering on central axis 3 by folk prescription; That is to say that during central axis 3 active rotation, no matter still rotate counterclockwise clockwise, the 3rd moving runner 503 rotates along with the rotation of central axis 3; But when the 3rd moving runner 503 active rotation, 3 folk prescriptions of central axis suppose promptly that to rotating along with the rotation of the 3rd moving runner 503 the 3rd moving runner 503 clockwise rotates, and central axis 3 clockwise rotates thereupon, the 3rd moving runner 503 rotates counterclockwise, and central axis 3 does not rotate thereupon.
In addition, the central axis driven end is provided with the aperture that laterally runs through wherein, and the direction of aperture is consistent with the diametric(al) in central axis 3 cross sections, is embedded with knob along its opening direction around the inwall of this aperture, when this knob, drive first moving runner 501 and rotate around central axis 3.The torsion spring constant force device here is similar to the transmission device of automobile, and when horizontal axle rotated, rotating shaft was longitudinally rotated thereupon, like this when carrying out reinforcing for torsion spring 6, operate more conveniently, the difficulty of having avoided elder generation to assemble for the torsion spring reinforcing has again reduced the difficulty of assembling.
This electric rolling device is provided with and draws curtain device, describedly draw curtain device to comprise to be socketed in first ropewinder 801, socket on the central axis driven end to be fixed on second ropewinder 802 near electric machine support 1 end the machine shaft, be arranged on the assembly pulley of roller shutter motion bar 9 and roller shutter far-end, this assembly pulley comprises two pulleys that are arranged on place, motion bar 9 two ends and two pulleys that are arranged on the two ends of roller shutter far-end.Backguy one end is wrapped on first ropewinder 801, through assembly pulley, be wrapped at last on second ropewinder 802, backguy on first ropewinder 801 around to on second ropewinder 802 around to consistent.In addition, on first ropewinder 801, have and the corresponding opening of described aperture, be beneficial to after assembling first ropewinder 801, can regulate constant force device.
Described assembly pulley can also replace with two pulleys that are arranged on the two ends of roller shutter far-end with a pulley that is arranged on motion bar 9 midpoint.
The overall schematic of electric rolling device as shown in Figure 3, when launching roller shutter cloth, motor rotates, and then first ropewinder 801 and second ropewinder 802 that are installed in the roller blind device two ends furl backguy synchronously, and this moment, motion bar 9 moved to the roller shutter far-end, second hollow section 402 is decontroled roller shutter cloth simultaneously, arrange exhibits at roller shutter and to end when finishing, when promptly motor stopped operating, the potential energy of torsion spring 6 discharged, drive second hollow section 402 and reverse by a small margin, thereby roller shutter cloth is straightened; When furling roller shutter cloth, motor reverses, and first ropewinder 801 and second ropewinder 802 unclamp backguy synchronously, furl roller shutter cloth by second hollow section 402, thereby has finished the process that roller shutter cloth launches and furls.
