Advantageously, linkage 29 comprises outer shape, and this outer shape coordinates with the interior shape of rolling tube 4.Therefore, the connection between linkage 29 and rolling tube 4 is ensured by the cooperation of matched shape.Like this, different rolling tube 4 types (these rolling tube 4 types can be manufactured by the manufacturer of masking device) can be adapted to from the linkage 29 that rolling tube 4 coordinates.
And, connection between linkage 29 and rolling tube 4 is ensured by the cooperation of matched shape, and limited mechanical play 18 is integrated in the interior linkage that the standard of linkage 29 can be restricted to without any integrated mechanical play of output shaft 12 of electric notor 11.
Such as, and the connection between linkage 29 and rolling tube 4 is ensured by the attachment arrangement making linkage 29 and be connected with rolling tube 4, one or more hold-down screw or one or more rivet.
At least one electronic control unit (not shown) is formed with for the device of the drive unit 5 driven by motor controlling the curtain 2 of masking device 3 according to the present invention.This electronic control unit can operate the drive unit 5 driven by motor.
Therefore, electronic control unit obviously controls the drive unit of electric notor 11, to roll or to launch curtain 2, as previously described, the existence of obstruction and/or end of travel supporter is located and in the moving process of curtain 2 by the relative rotation detected between first element and the second element 16,17 of output shaft 12.
Hardware and/or software service are comprised to the control device that the drive unit of the curtain 2 for driving masking device 3 controls.
As non-limiting example, hardware unit can comprise at least one microcontroller.
Pass through the present invention, electric notor for the drive unit driven by motor of the rolling tube of the curtain of masking device comprises the mechanism possessing limited angle machine tool play, this mechanism is integrated in its output shaft, to detect the existence of obstruction and/or end of travel supporter in the moving process of the curtain of masking device.
Like this, electric notor can not be arranged on the external accessory on its output shaft, and comprises the mechanism possessing limited mechanical play.
This electric notor (this mechanism is integrated in the output shaft of electric notor) comprising the mechanism possessing limited mechanical play can use any linkage that the output shaft of electric notor is connected with rolling tube, particularly any external accessory, this external accessory does not possess the mechanism of limited mechanical play.Therefore, the linkage not possessing any mechanism of limited mechanical play is used to be connected the connection mechanical strength that can improve between the output shaft and rolling tube of electric notor with rolling tube to make the output shaft of electric notor.
The amplitude mechanism possessing limited mechanical play being integrated in the output shaft of electric notor the angular displacement part of the limited mechanical play that can also make between first element and the second element of output shaft adapts to the technical characteristic of electric notor.
Alternatively, output shaft can comprise the parts except element 16 and 17, and especially, third element can be axial symmetry parts.
Certainly, without departing from the scope of the invention, multiple change can be carried out to foregoing one exemplary embodiment.
Especially, the first element of output shaft and the material of the second element can be different, can be metal particularly.Above-described embodiment and optional manner can be combined, for generation other embodiments of the invention.
