A pedestal 55f being located at below screw rod 55a can be further set in the upper beam 51 in the bottom surface of upper beam 51 to be located at vertical Plate body 55g on pedestal 55f, pedestal 55f can be used to the moving part 55e that is pivoted, and plate body 55g then can be used to fix damper 55c And the clamping piece 55d that is pivoted, those elements is incorporated into the way of modularity in upper beam 51.

Damper 55c, which is further disclosed, has an a housing 55c2 and tumbler 55c1, and housing 55c2 one end has It is correspondingly arranged with clamping piece 55d, and the engaging tooth 55c2a that can be engaged with clamping piece 55d, the clamping piece 55d claw end 55d1 For close to engaging tooth 55c2a one end, by being one end away from engaging tooth 55c2a to end 55d2.Because clamping piece 55d can be in upper Pivot is put in beam 51, when claw end 55d1 is located at first position P1, is engaged with engaging tooth 55c2a, during positioned at second place P2, claw It is to depart from away from engaging tooth 55c2a, and with engaging tooth 55c2a to hold 55d1；In addition, to make clamping piece 55d before non-pivot pendulum, card Pawl end 55d1 engages positioned at first position P1 with engaging tooth 55c2a, and clamping piece 55d pivot can be set for the eccentric (such as first The pivot of embodiment is set), or clamping piece 55d includes the bullet for being arranged on and being opened in upper beam 51 or plate body 55g receiving space Property reset element 55d3 (as shown in figure 21), certainly, elastic reset member 55d3 set-up mode is not limited, and can also be set Between clamping piece 55d and the clamping piece 55d that is pivoted upper beam 51 or plate body 55g, make clamping piece 55d before non-stress pivot pendulum, Elastic reset member 55d3 restoring force perseverance makes claw end 55d1 engage in first position P1 with engaging tooth 55c2a.

Tumbler 55c1 is in housing 55c2, between tumbler 55c1 and screw rod 55a and to be arranged an one-way clutch 57, in screw rod 55a drive the one-way clutch 57 rotate when, one-way clutch 57 can drive tumbler 55c1 and meanwhile rotate or Individually rotated relative to tumbler 55c1；Interlock screw rod 55a to fold the rotation side of masking structure 53 in drive mechanism 56 Xiang Shi, one-way clutch 57 is individually rotates relative to tumbler 55c1, and it is expansion to interlock screw rod 55a in drive mechanism 56 During the rotation direction of masking structure 53, one-way clutch 57 and tumbler 55c1 is rotation simultaneously.In the present embodiment, unidirectionally Clutch 57 is that for using roll clutch (roller clutch, roller clutch), but the structure system of one-way clutch 57 is Prior art, not in the technical characteristic of this case, therefore is not repeated herein.

In the present embodiment, power controller 54 can be fake formula controller, and fake 54a can be for rope fake (such as Shown in Figure 20), can also be other fake, such as pelletron fake (not shown).

The masking structure 53 when folding completely, and the stroke nut 55b on screw rod 55a is away from clamping piece 55d, moving part 55e and clamping piece 55d are not put by ejection pivot, and clamping piece 55d is the gravity or elastic reset member produced by eccentric pivots 55d3 restoring force, make clamping piece 55d claw end 55d1 be located at first position P1, and with housing 55c2 engaging tooth 55c2a Engaging, to fix housing 55c2.

The masking structure 53 be released and deploy it is initial during, it is downwards by masking structure 53 and the weight of underbeam 52 Pulling force drives drive mechanism 56 to be rotated towards the direction of expansion masking structure 53, and drives screw rod 55a and one-way clutch simultaneously 57 rotate, because in this rotation direction, one-way clutch 57 is combined with damper 55c tumbler 55c1, tumbler 55c1 It is driven and is rotated simultaneously with one-way clutch 57；Now, because clamping piece 55d is not affected by contact pivot pendulum, claw end 55d1 is Positioned at first position P1, engage with housing 55c2 engaging tooth 55c2a, housing 55c2 is thus fixed, therefore turn in tumbler 55c1 When dynamic, damper 55c is one drag of output, and make tumbler 55c1 velocity of rotation is reduced by the interference of the drag, One-way clutch 57, screw rod 55a and drive mechanism 56 with tumbler 55c1 gearings is reduced also by the interference of the drag Its velocity of rotation, the damper 55c in this stage is provides drag, with damping.

With the process that masking structure 53 is gradually spread out, screw rod 55a driven-mechanisms 56, which drive, to be rotated, stroke nut 55b Clamping piece 55d directions are axially facing along screw rod 55a length to move, and be moved to ejection moving part 55e mono- in stroke nut 55b During end, moving part 55e stress pivot pendulum, the moving part 55e other ends be contact clamping piece 55d by end 55d2, to drive blocking Part 55d pivots are put, and make clamping piece 55d claw end 55d1 by the first position P1 directions and engaging tooth that engages with engaging tooth 55c2a The second place P2 directions movement that 55c2a departs from, as stroke nut 55b continues to move towards clamping piece 55d directions, moving part 55e pivot swinging becomes big, and the angle that claw end 55d1 is turned also becomes big, continues to be directed away from the second of engaging tooth 55c2a Position P2 directions are moved, and when claw end 55d1 is located at second place P2, is departed from housing 55c2 engaging tooth 55c2a, made Housing 55c2 is free to rotate, and housing 55c2 is driven by tumbler 55c1 and rotated simultaneously, now, though damper 55c is by band It is dynamic to rotate, but drag is not exported, thus do not have damping, tumbler 55c1, one-way clutch 57, screw rod 55a and drive The velocity of rotation of motivation structure 56 is not affected by the interference of drag, i.e., turned to original speed and be fully deployed masking structure 53.

In addition, drive drive mechanism 56 to rotate with the fake 54a of power controller 54, to fold during masking structure 53, Drive mechanism 56 is drives screw rod 55a to rotate simultaneously, and now, the rotation direction for folding masking structure 53 makes one-way clutch 57 Depart from damper 55c tumbler 55c1, one-way clutch 57 is individually to be rotated relative to tumbler 55c1, damper 55c is not driven and does not export drag.And when screw rod 55a is rotated, stroke nut 55b is the axial court of length along screw rod 55a Direction movement away from clamping piece 55d, moving part 55e no longer stress pivots are put and turn clamping piece 55d, and clamping piece 55d can be by The gravity or elastic reset member 55d3 restoring force produced by eccentric pivots makes clamping piece 55d carry out pivot pendulum, claw end 55d1 Moved, and when stroke nut 55b is moved to no longer ejection moving part 55e, made from second place P2 to first position P1 directions Claw end 55d1 is located at first position P1, and engages with engaging tooth 55c2a, to fix housing 55c2.

In the present embodiment, because honeycomb curtain when folding completely, because the downward pulling force of weight generation removes underbeam 52 certainly Outside the weight of body, still including stacking in the weight of masking structure 53 on underbeam 52, therefore, downward pulling force is received completely in honeycomb curtain Maximum is reached during conjunction, in deploy masking structure 53 it is initial when, by maximum downward pulling force pulling, the rotation of drive mechanism 56 Speed is accelerated, and is rapid deployment masking structure 53, now it is necessary to a drag be exported by damper 55c, to reduce driving machine The velocity of rotation of structure 56, and gradually spreading out with masking structure 53, stack and are gradually decreased in the masking structure 53 on underbeam 52, Because the downward pulling force of weight generation is also tapered into, the velocity of rotation of driving structure 56 is slack-off, therefore is expanded in masking structure 53 When necessarily hanging down long, you can stop the output of the drag, to maintain the velocity of rotation of drive mechanism 56.

It this concludes the description of the present invention and its embodiment.It should be noted that, described embodiment in this specification Merely illustrative, the present invention is not exposed to the limitation of these embodiments.It will be appreciated by those skilled in the art that not departing from this hair In the range of light staining center thought, any change or addition can be carried out to embodiment, for example, the zero of above-mentioned each embodiment record Part can also be mutually combined.Therefore, record of the protection scope of the present invention comprising claims and its equivalent substitution.
