Figure 16 to Figure 26 systems illustrate the damping adjustment device 500 of the embodiment of the present invention.In Figure 16 to 21, damping regulation dress Putting 500 includes damping output module 510a and damping control module 530, and damping output module 510a includes the first damping piece The the first damping piece 512a of 512a and the second damping piece 514a, wherein damping control module 530 only with damping output module 510a Interlock.

Figure 16 to 18 is refer to, damping control module 530 includes travel mechanism 532, and this travel mechanism 532 drives first to hinder Damping member 512a is with shifting axle 5325 for axle center synchronous rotary.Specifically, travel mechanism 532 includes screw rod 5321, axle sleeve 5323 And pedestal 5326.Axle sleeve 5323 is sheathed on one end of screw rod 5321, and is fixedly arranged on pedestal 5326.The external screw thread of screw rod 5321 5322 mutually screw with the internal thread 5324 of axle sleeve 5323.Because axle sleeve 5323 is to be fixedly arranged on pedestal 5326, therefore work as screw rod During 5321 rotation, screw rod 5321 can move along the axial movement of axle 5325.On the other hand, the first of damping output module 510a Damping piece 512a is connected to the other end of screw rod 5321, and when screw rod 5321 is rotated, screw rod 5321 can drive the first damping piece 512a is rotated.In an embodiment of the present invention, shifting axle 5325, the rotating shaft of screw rod 5321 and the first damping piece 512a rotating shaft 5122a is coaxially disposed.In other embodiments of the invention, shifting axle 5325, the rotating shaft of screw rod 5321 and the first damping piece Can be parallel, coaxial or the two combination between 512a rotating shaft 5122a.For blind system 10, drive device 200 has one Drive shaft, this drive shaft and the shifting axle 5325 of travel mechanism 532 are coaxially disposed, and drive device 200 makes the band of travel mechanism 532 Dynamic first damping piece 512a is with shifting axle 5325 for axle center synchronous axial system.

Damping output module 510a the second damping piece 514a systems are sheathed on the first damping piece 512a, and the first damping piece 512a systems are arranged between the damping piece 514a of travel mechanism 532 and second.Furthermore, it is understood that travel mechanism 532 is arranged on second Between damping piece 514a and drive device 200.When 532 start of travel mechanism, travel mechanism 532 can drive the first damping piece 512a interacts work to change relative to the second damping piece 514a displacements between the first damping piece 512a and the second damping piece 514a Firmly.In detail, when the screw rod 5321 of travel mechanism 532 is rotated, screw rod 5321 can move along the axial movement of axle 5325, Drive the first damping piece 512a to move along the axial movement of axle 5325 simultaneously, and make the first damping piece 512a relative to the second resistance Damping member 514a produces displacement, further changes the interactive forces between the first damping piece 512a and the second damping piece 514a.

Then it please coordinate with reference to Figure 19 to 21, wherein the first damping piece 512a systems are by taking elastomer as an example, this elastomer is included Elastic component 5121a, brake pad 5123a and pedestal 5125a, elastic component 5121a and brake pad 5123a are connected to each other, and elastic component 5121a and brake pad 5123a are all installed on pedestal 5125a；And second damping piece 514a systems by taking hollow sleeve as an example, it is and hollow The inwall 5141a of sleeve part system is general in cone.First damping piece 512a elastomer and the second damping piece 514a's Inwall 5141a contact, elastomer has rotating shaft 5122a, and elastomer rotates by axle center of rotating shaft 5122a, make elastomer with it is interior Friction force is produced between wall 5141a.In Figure 19, elastic component 5121a is arranged in pedestal 5125a, and two brake pad 5123a Elastic component 5121a two ends are installed in respectively, are arranged symmetrically in relation to each other two brake pad 5123a.In fig. 20, elastic component 5121a One end be fixedly arranged on pedestal 5125a, its other end connection brake pad 5123a, make brake pad 5123a present it is asymmetric set.
