Detailed description of the invention
Below in conjunction with accompanying drawing, by the specific embodiment of the present invention describe in detail, will make technical scheme of the present invention and other beneficial effects apparent.
The invention provides a kind of roller shutter drive device, comprise motor and electromagnetic brake.Motor is used for the spool rotating roller shutter directly or indirectly, makes roller shutter be wound up into spool or unfolds from spool, and described roller shutter can be flexible rollable curtain, door curtain, screen etc., also can be rolling door.Electromagnetic brake is connected with the rotating shaft of motor, and the lock out motor when motor stops, preventing electric machine rotation, thus roller shutter is remained on the position wanted.
Fig. 1 is the decomposing schematic representation of the roller shutter drive device of one embodiment of the invention.This roller shutter drive device comprises gear-box 10, motor 30 and electromagnetic brake 50.The gear that gear-box 10 comprises shell 11, end cap 13 and is arranged in shell 11, end cap 13 is fixed to shell 11 by screw 12.Gear-box 10 is installed to the front end of motor 30, rotates for driving spool as deceleration device.Motor 30 comprises stators and rotators, and stator comprises shell 32 and end cap 33 etc., and rotor can relative to stator rotation and by rotating shaft 31 driving gearbox 10.Motor 30 is connected to external power source by wire 34.Electromagnetic brake 50 is installed to the rear end of motor 30, for the braking motor when motor stops, preventing the rotating shaft 31 of motor from rotating when motor stops.Have spiral piping arrangement in electromagnetic brake, in use, spiral piping arrangement and motor be energized simultaneously, simultaneously power-off.In the present embodiment, solenoidal line end 55 is in parallel with the line end 34 of motor.
Fig. 2 is the exploded perspective view of electromagnetic brake 50 shown in Fig. 1, and Fig. 3 is the end-view of electromagnetic brake 50, and Fig. 4 is the schematic diagram of electromagnetic brake along the cutting of A-A face.As shown in Figures 2 to 4, tumbler 58, friction member 57, spring 56 and spiral piping arrangement that electromagnetic brake comprises shell 51, end cap 60 and installs in the enclosure, wherein, spiral piping arrangement comprises iron core 52, is set in coil holder 54 outside iron core and coil 63 thereof.End cap 60, tumbler 58, friction member 57 and spiral piping arrangement axially-aligned in turn.Tumbler 57 is disk like, and has air gap between end cap 60 so that rotate.The rotating shaft 31 of motor 30 is passed the end cap 60 of electromagnetic brake and is engaged with the through hole 59 of tumbler 58, and tumbler 58 can be rotated together along with rotating shaft 31.Preferably, the through hole 59 of tumbler 58 is positioned at the center of tumbler 58, and the cross section of through hole is the band square hole of fillet or the hole with two flat position, and the cross section of driving shaft 31 has corresponding shape and mates with through hole.
Tumbler 58 has a rubbing surface near friction member 57, and this rubbing surface is basically perpendicular to rotating shaft 31.In the present embodiment, friction member 57 is plane or disk like, can move axially within the specific limits, and axial arranged helical spring 56 pairs of friction members 57 apply elastic force, makes friction member 57 and the attrition surface friction of tumbler 58, realizes the braking to tumbler 58.When tumbler 58 is braked, rotating shaft 31 can not rotate, thus prevent roller shutter that undesired slip occurs.The rubbing surface of tumbler 58 can be its dish face, also can be the plane formed from the flange that the edge of tumbler 58 is protruding vertically.
The rear end of the iron core 52 of spiral piping arrangement is installed to the bottom of shell 51, and front end is near friction member 57, and front end has axial shrinkage pool 53 for mounting spring 56, and in the present embodiment, spring 56 is helical springs by compression.The spiral winding of spiral piping arrangement is wrapped on coil holder 54, and coil holder 54 is sleeved on the outer surface of iron core 52.To produce magnetic field after spiral winding energising, this magnetic field absorption friction member 57 makes friction member 57 overcome the elastic force of spring 56 with close iron core 52, thus makes friction member 57 depart from the attrition surface of tumbler 58, removes the braking to tumbler 58.Preferably, on circuit connecting relation, spiral winding and motor parallel, realize connecting simultaneously and disconnecting simultaneously, like this, when electrical power runs, tumbler 58 is by brake off; And during motor closedown, tumbler 58 is braked.
In the present embodiment, electromagnetic brake end cap 60 is fixed to shell 51 by screw 61, elongated slide bar 62 axially penetrate electromagnetic brake end cap 60 and shell 51, as the slide rail of friction member 57.Accordingly, the edge of friction member 57 has some breach 571 and some breach 572, wherein, the size of breach 571 is corresponding to screw 61 interference avoided screw 61, and the size of breach 572 is corresponding with slide bar 62, so that friction member 57 can move axially along slide bar 62 and be limited to rotate.Therefore, the radial dimension of tumbler 58 should be less than the radial dimension of friction member 57, to avoid interfering with slide bar 62.
In the present embodiment, the through hole of tumbler 58 has flange 59, and a part for flange 59 protrudes from tumbler 58 vertically, and this flange 59 can strengthen the close-fitting of tumbler 58 and rotating shaft 31.There is through hole to accommodate this wheel hub in the middle of friction member 57.The radial dimension of helical spring 56 is greater than the aperture of the through hole of friction member 57.Correspondingly, the centre of end cap 60 has through hole to expose wheel hub.
The above, for the person of ordinary skill of the art, can make other various corresponding change and distortion according to technical scheme of the present invention and technical conceive, and all these change and be out of shape the protection domain that all should belong to claim of the present invention.
