Abstract

A damping adjustment device for adjusting a damping force to a window covering system while the window covering system is expanding, wherein the damping adjustment device comprises a damping module comprising first and second damping units. The damping force is outputted by the damping module to the window covering system when the first and second damping units generate an interaction force in between by a relative motion therebetween. An adjusting module is connected to the damping module for operating with the damping module simultaneously, wherein the damping force from the damping module is adjusted by the adjusting module altering a relative position of the first damping unit and the second damping unit when the relative motion occurs therebetween. A window covering system comprises the damping adjustment device, wherein expansion speed of a covering material of the window covering system can be effectively controlled and adjusted by the damping adjustment device.

Dependent claims

A damping adjustment device for outputting a damping force to a window covering system in an adjustable manner while the window covering system is expanding, comprising:

a damping module which comprises a first damping unit and a second damping unit, wherein the first damping unit and the second damping unit are adapted to have a relative motion to generate an interaction force therebetween, by which the damping module outputs the damping force to the window covering system;
and
an adjusting module connected to the damping module for operating with the damping module simultaneously, wherein the adjusting module is adapted to alter a relative position of the first damping unit and the second damping unit when the first damping unit and the second damping unit have the relative motion, whereby to change the interaction force therebetween and therefore adjust the damping force outputted from the damping module;
wherein the adjusting module comprises a shifting assembly connected to the first damping unit for moving the first damping unit in order to alter the relative position of the first damping unit and the second damping unit;
wherein the adjusting module further comprises a connecting rod with two ends, wherein the shifting assembly is connected to one end and the second damping unit is connected to the other end, whereby the shifting assembly and the second damping unit are configured to operate simultaneously for altering the relative position of the first damping unit and the second damping unit;
wherein the second damping unit comprises a rotation axis, and the second damping unit rotates about the rotation axis;
the connecting rod is parallel to the rotation axis of the second damping unit.

a covering material;
a driving device to be driven by the covering material while the covering material is expanding or collecting;
and
a damping adjustment device connected to the driving device, wherein the damping adjustment device comprises a damping module and an adjusting module, wherein the damping module is configured to output a damping force to the driving device, and the damping module comprises a first damping unit and a second damping unit, wherein the first damping unit and the second damping unit are configured to generate an interaction force in between by a relative motion between the first damping unit and the second damping unit while the driving device is driven by expansion of the covering material,
and the adjusting module is connected to the damping module and the driving device, wherein the adjusting module is configured to operate with the damping module simultaneously for adjusting the damping force to the driving device by altering a relative position of the first damping unit and the second damping unit when the relative motion occurs between the first damping unit and the second damping unit;
wherein the adjusting module comprises a shifting assembly connected to the first damping unit and the driving device, wherein the shifting assembly and the driving device are configured to operate simultaneously, wherein the relative position of the first damping unit and the second damping unit is altered by the shifting assembly when the shifting assembly moves the first damping unit;
wherein the adjusting module further comprises a connecting rod with two ends, wherein the shifting assembly is connected to one end and the second damping unit is connected to the other end, wherein the shifting assembly and the second damping unit are configured to operate simultaneously via the connecting rod for altering the relative position of the first damping unit and the second damping unit;
wherein the second damping unit comprises a rotation axis, and the second damping unit rotates about the rotation axis;
the connecting rod is parallel to the rotation axis of the second damping unit.
