In this embodiment, a protrusion 337 is provided on a gear shaft of the fifth gear 335, a groove 327 is provided on a gear shaft of the second timing pulley 323, when the fifth gear 335 and the second timing pulley 323 are normally assembled, the protrusion 337 is inserted into the groove, so that the fifth gear 335 and the second timing pulley 323 can be synchronously driven, the width of the protrusion 337 is smaller than the width of the groove 327, a gap is formed between groove walls of the protrusion 337 and the groove 327, a damper 336 is provided in the gap, when a damping force of the damper 336 is larger than a driving force of the first timing belt 312 and smaller than a driving force of the second timing belt 322, the fifth gear 335 slips relative to the second timing pulley 323, and the second timing pulley 323 normally rotates; when the damping force of the damper 336 is smaller than the driving force of the first synchronous belt 312 and larger than the driving force of the second synchronous belt 322, the second synchronous belt wheel 323 slips relative to the fifth gear 335, and the fifth gear 335 rotates normally, so that the lengths of the first hanging rod 310 and the second hanging rod 320 are different, and the hanging rod 300 can be applied to more scenes, and the adaptability is stronger.

Specifically, the protrusion 337 may be an annular protrusion designed around the edge of the gear shaft, and the groove 327 is correspondingly configured as an annular groove disposed around the inside of the gear shaft, so that the protrusion 337 and the groove 327 are matched in shape, and the fifth gear 335 and the second synchronous pulley 323 are cooperatively driven.

Generally, the damping force of the damper 336 can be designed according to the length of the hanging rod, taking the example that the length of the first hanging rod 310 is shorter than that of the second hanging rod 320 as an example, correspondingly, the length of the first synchronous belt 312 is shorter than that of the second synchronous belt 322, the damper 336 is arranged between the gear shaft of the second synchronous pulley 323 and the fifth gear 335, the damping force of the damper 336 is set to be larger than the driving force of the first synchronous belt 312 and smaller than that of the second synchronous belt 322, through the action of the damper 336, when the first synchronous belt 312 runs to the head, the fifth gear 335 slips on the damper 336 and rotates in place, and the second synchronous pulley 323 can normally rotate to drive the second synchronous belt 322 to normally drive, so that the length of the two hanging rods is different.

On the contrary, when the length of the first synchronous belt 312 is longer than that of the second synchronous belt 322, the damping force of the damper 336 is smaller than the driving force of the first synchronous belt 312 and larger than the driving force of the second synchronous belt 322, so as to ensure that the curtains on the two hanging rods are normally driven at the same time. Of course, the damper 336 may be provided between the first timing pulley 313 and the fourth gear 334 to ensure a proper transmission.

In this embodiment, the damper 336 may also be replaced by damping oil, and similarly, by selecting the damper 336 or damping oil with a suitable specification according to the length of the hanging rod, the curtains on both sides may still run simultaneously to shade light under the condition that the first hanging rod 310 and the second hanging rod 320 are different. Moreover, the method also omits an electromagnetic clutch device, reduces the cost and the complexity of the structure, and leads the performance of the product to be more excellent.

In addition, when the included angle between the first hanging rod 310 and the second hanging rod 320 is greater than or equal to 90 °, the first dimming axis 51 and the second dimming axis 52 can rotate normally to perform dimming; meanwhile, the normal transmission function of the first synchronous belt 312 and the second synchronous belt 322 is met, so that the hanging rod 300 can be suitable for various special-shaped floating curtains or U-shaped curtains at 90-180 degrees, and the universality is higher.

Usually, the hanging rod 300 is folded manually, so as to facilitate the judgment of the folding angle by the user, and reduce the phenomenon that the synchronous belt is damaged due to the fact that the included angle between the first hanging rod 310 and the second hanging rod 320 is too small to start the transmission case.
