Body one end is connect with the clutch, and the clutch other end is connect with the transmission mechanism, the biography
The motivation structure other end is connected with shade rollerl blind shaft and can be rotated coaxially with shade rollerl blind shaft, when roller shutter winding, the clutch
So that the transmission mechanism is connect with the retarder main body, thus by making to brake caused by the retarder main body
Power passes to the transmission mechanism and shade rollerl blind shaft, and when roller shutter stretching, extension, the clutch makes the driver
Structure is disconnected with retarder main body, will not increase resistance of the curtain in stretching, extension in this way.
As a preferred embodiment of the present invention, the retarder main body includes retarder casing and retarder core,
Retarder casing one end is equipped with room, at least a pair of of convex-concave annulus is equipped in room, the retarder core has and retarder
The convex-concave annulus of the mutual clearance fit of convex-concave annulus is placed in retarder casing room in shell room；
The clutch includes the clutch disc of retarder body side, which is fixed on window through retarder main body
In curtain fixing axle and the clutch disc of transmission mechanism side, which can be with transmission mechanism integrated rotary and can be along window
The fixed axis direction of curtain is free to slide, and clutch teeth is equipped between two clutch disc, which engages when roller shutter is wound,
And it is not engaged in roller shutter stretching, extension；
The transmission mechanism includes driving wheel and transmission shaft, and driving wheel one end passes through the clutch of transmission shaft and transmission mechanism side
The connection of device piece, driving wheel one end are connect with shade rollerl blind shaft, and the clutch disc of driving wheel, transmission shaft and transmission mechanism side together may be used
It is rotated with shade rollerl blind shaft.
Further, the clutch further includes a spring-feel mechanism, and the spring-feel mechanism makes to pass
The clutch disc of motivation structure side is loaded to the clutch disc of retarder body side, so that clutch teeth winds occasion in roller shutter
It is closer to need to engage engagement, so as to effectively prevent the appearance of meshing gear slipping phenomenon.
The clutch disc of the transmission mechanism side is ratchet-gear wheel, and the clutch disc of retarder body side has and institute
The tooth for the ratchet-gear wheel engagement stated, the clutch disc of the retarder body side and the retarder core are integrally formed.
For the retarder body side there are also sealing cover, the sealing cover makes the room of retarder casing form closing
Space, be full of damping oil in the room of the retarder casing, in this way when transmission mechanism drive retarder chip relative to
Retarder casing generates brake force when rotating.
Beneficial effects of the present invention: the present invention, which is mounted in the curtain of automatic winding when can be effectively reduced curtain coiling, especially to exist
Strike note at the end of winding soon will not increase pulling force when curtain stretching, extension simultaneously, to improve the stability that curtain uses
And the service life.
Detailed description of the invention
Fig. 1 is electrically driven curtain deceleration system explosive view of the present invention；
Fig. 2 is electrically driven curtain deceleration system sectional arrangement drawing of the present invention.
Specific embodiment
With reference to Fig. 1 and Fig. 2, a kind of electrically driven curtain deceleration system provided by the invention, including retarder main body 10, clutch
Structure 20 and transmission mechanism 30.
Retarder main body 10 includes retarder casing 11 and retarder core 12, and 11 one end of retarder casing has protruding shaft 11-
1,11 one end of retarder casing has protruding shaft 11-1, and 11 other end of retarder casing has container 11-2, has in container 11-2
Convex-concave annulus 11-2-1,12 one end of retarder core have the convex-concave annulus 12-1 with convex-concave annulus 11-2-1 clearance fit, slowly
There are also sealing cover 13, sealing covers 13 to be connect with retarder casing 11 by screw 14 for device body side, and the sealing cover 13 makes
The room 11-2 of retarder casing 11 forms closed space, is full of damping in the room 11-2 of the retarder casing 11
Oil.
The clutch disc 21 of clutch 20 including retarder body side, the clutch disc 21 and retarder core 12 can one
Body formed, clutch disc 21 can also be otherwise coupled to retarder core 12 and the clutch disc 22 of transmission mechanism side,
Clutch disc 22 can be ratchet-gear wheel, or other structures, clutch disc 22 can be with 30 integrated rotaries of transmission mechanism and can
It is free to slide along curtain fixing axle (not shown) direction, clutch teeth 23, the clutch teeth are equipped between two clutch disc
It engages in roller shutter winding, and is not engaged in roller shutter stretching, extension；
Transmission mechanism 30 includes transmission shaft 31 and driving wheel 32, the company of clutch disc 22 of 31 one end of transmission shaft and transmission mechanism side
Connect, make the clutch disc 22 of 30 side of transmission mechanism with 31 synchronous rotary of transmission shaft, 31 other end of transmission shaft by screw 33 with
Driving wheel 32 connects, in this way when curtain shaft (not shown) rotates, drive transmission shaft 31 and 30 side of transmission mechanism from
Clutch piece 22 rotates synchronously together, and for 24 sets of loading mechanism (such as spring) on transmission shaft 31, sealing cover 13 is tight by loading mechanism 24
It is pressed in the side of the clutch disc 22 of transmission mechanism side, makes the clutch disc 22 of 30 side of transmission mechanism to retarder master in this way
The clutch disc 21 of 10 side of body loads, so that clutch teeth 23 needs engagement engagement closer in roller shutter winding occasion, thus
It can effectively prevent the appearance of 23 slipping phenomenon of meshing gear.
In this way, but when roller shutter automatic winding, shade rollerl blind shaft (not shown) drives driving wheel 32, transmission shaft 31 and clutch
Piece 22 rotates synchronously, and at this moment, clutch disc 22 and engage with the integrally formed clutch disc 21 of retarder core 12, drive retarder
Core 12 and retarder casing 11 generate brake force by the relative rotation full of damping oil bumps annulus, so as to effectively drop
When low curtain coiling especially winding soon at the end of strike note, when roller shutter stretching, extension, shade rollerl blind shaft (not shown) also band
Dynamic driving wheel 32, transmission shaft 31 and clutch disc 22 rotate backward, and at this moment, clutch disc 22 and are integrally formed with retarder core 12
Clutch disc 21 do not engage, retarder core 12 and retarder casing 11 pass through full of damping oil bumps annulus will not opposite rotation
Turn, brake force will not be generated, therefore, the retarder not will increase the resistance of curtain when roller shutter stretching, extension, so that curtain is being stretched
It is more labor-saving when exhibition.
Above disclosed is only presently preferred embodiments of the present invention, not does limit in any form to the present invention
System, although the present invention is disclosed above in the preferred embodiment, and the non-limiting present invention, any person skilled in the art
In the range of not departing from technical solution of the present invention, changes or repair a little when being made using above-mentioned revealed technology contents
Decorations are the equivalent embodiment of equivalent variations, according to equivalent variations made by scope of the present invention patent, still belong to the present invention and are covered
