The opening and closing limiting component 32 in this embodiment is a block with a clamping structure, and a channel for the movement of the opening and closing limiting component 32 is reserved inside the track main body 11.

Preferably, the supporting body 2111 adjacent to the two opening/closing limiting assemblies 32 is provided with a magnetic portion (not shown), and the magnetic portions of the two supporting bodies 2111 attract each other, so that the dimming mechanisms 2 adjacent to the two opening/closing limiting assemblies 32 are magnetically attracted together. It can be understood that, the mechanism 2 of adjusting luminance adjacent to two spacing subassemblies 32 that open and shut respectively is the division point that the curtain opened the curtain action perpendicularly, after closing the curtain, make two mechanisms 2 of adjusting luminance of division point department adsorb together through the setting of magnetism portion of inhaling, can guarantee to close the curtain state, and under closing the curtain state, when needing to adjust luminance the curtain piece that covers on the window, then need the flexible subassembly 31 of opening and shutting to drive the runner piece 241 and rotate, two mechanisms 2 of adjusting luminance of division point department adsorb together still can be guaranteed to magnetism portion of inhaling this moment, maintain and close the curtain state, guarantee to close the smooth going on of adjusting luminance under the curtain state.

With continued reference to fig. 2 and 13, fig. 13 is an enlarged view of the portion C of fig. 2 in this embodiment. Furthermore, the light-adjusting opening and closing device in this embodiment further includes a curtain-opening limiting mechanism 4. The curtain opening limiting mechanism 4 comprises a plurality of curtain opening limiting assemblies 41. A curtain opening limiting component 41 is arranged between two adjacent bearing components 21, and two ends of the curtain opening limiting component 41 are movably connected with the two adjacent bearing components 21 respectively. The curtain opening limiting component 41 limits the maximum curtain opening degree between two adjacent bearing components 21, when the limiting transmission component 22 reaches the stroke limiting state and the bearing components 21 reach the maximum curtain opening degree, the flexible opening and closing mechanism 3 drives the rotating wheel 241 to rotate, and the rotating wheel 241 and the elastic component 242 rotate in a friction mode. Through the arrangement of the curtain opening limiting component 41, the maximum curtain opening degree of the two adjacent bearing components 21 is limited, so that the accurate execution of the curtain opening action is ensured. Specifically, two ends of the curtain opening limiting component 41 are respectively provided with a limiting protrusion 411, and the bearing main body 2111 is provided with a limiting sliding groove 2114. The curtain opening limiting component 41 is slidably connected in the limiting sliding grooves 2114 of two adjacent bearing main bodies 2111, and the two limiting protrusions 411 are respectively located on the outer sides of the two adjacent bearing main bodies 2111 which are opposite to each other. When the limiting sliding groove 2114 slides relative to the curtain opening limiting component 41, and when the two adjacent bearing main bodies 2111 respectively abut against the limiting protrusions 411 at the two opposite ends of the curtain opening limiting component 41, the maximum distance between the two adjacent bearing main bodies 2111 is reached, that is, the maximum curtain opening degree of the two adjacent bearing components 21 is limited, and the distance between the two adjacent bearing main bodies 2111 is the curtain opening degree.

It can be understood that after the maximum opening degree of two adjacent bearing assemblies 21 is reached, the flexible opening and closing assembly 31 will continue to rotate to drive the other subsequent dimming mechanisms 2 to move, and at this time, the two adjacent bearing assemblies 21 that have reached the maximum opening degree are no longer moving. In this embodiment, the elastic member 242 forms a sleeving relationship with the rotating wheel 241 by using its own elastic characteristic, when the flexible opening and closing member 31 continues to act on the bearing member 21 reaching the maximum opening and closing degree, the limit transmission member 22 is located at the stroke limit again, at this time, the acting force of the flexible opening and closing member 31 on the rotating wheel 241 is greater than the acting force between the elastic member 242 and the rotating wheel 241, so that the elastic member 242 and the rotating wheel 241 perform relative friction and rotate in a staggered manner, even if the flexible opening and closing member 31 continues to move, two adjacent dimming mechanisms 2 reaching the maximum opening and closing degree do not move any more, the cooperation between the elastic member 242 and the rotating wheel 241 is similar to a clutch structure, and damage to the dimming mechanisms 2 is avoided.

The dimming process in this embodiment is as follows: in a curtain closing state, the flexible opening and closing assembly 31 drives the rotating wheel piece 241 to rotate, the rotating wheel piece 241 drives the elastic piece 242 to rotate, the first acting end 2421 or the second acting end 2422 of the elastic piece 242 acts on the shifting plate 22121 to push the transmission sleeve 2212 to rotate, the transmission sleeve 2212 drives the transmission wheel 2213 to rotate, the transmission wheel 2213 drives the limiting piece 222 to rotate, and the limiting piece 222 drives the curtain piece on the hook piece 231 of the curtain piece mounting assembly 23 to rotate, so that the dimming of the curtain piece is realized. When the stop block 2221 abuts against the end of the arc-shaped stop block 21132, the rotation stroke is limited, and the curtain sheet is at the maximum angle of rotation, i.e. the maximum angle of dimming. The maximum dimming angle in this embodiment is 90 degrees.

The curtain opening and closing process in the embodiment is as follows: in the curtain closing state, when the rotation state of the limiting member 222 is blocked by the arc-shaped limiting block 21132, and the maximum dimming angle is reached, the limiting member 222 does not rotate any more, the elastic member 242 and the rotating wheel member 241 do not rotate any more, at this time, the flexible opening and closing assembly 31 drives the rotating wheel member 241 to move, the rotating wheel member 241 drives the bearing main bodies 2111 to slide in the opening and closing track groove 12, so that two adjacent bearing main bodies 2111 approach each other, when two adjacent bearing main bodies 2111 abut against each other, the rotating wheel member 241 and the elastic member 242 rub against each other, and rotate in a staggered manner, at this time, the flexible opening and closing assembly 31 can drive the rotating wheel member 241 on the bearing main body 2111 which has already abutted against to rotate, and simultaneously drive the rotating wheel member 241 on the bearing main body 2111 which has not. When the curtain is closed, the flexible opening and closing component 31 starts to rotate reversely, the flexible opening and closing component 31 drives the rotating wheel piece 241 to rotate firstly, after the braking block 2221 abuts against the other end part of the arc-shaped limiting block 21132, the flexible opening and closing component 31 drives the rotating wheel piece 241 to move, so that two adjacent bearing main bodies 2111 are far away from each other, when the two adjacent bearing main bodies 2111 are limited by the opening and closing limiting component 41 to reach the maximum opening degree, the rotating wheel piece 241 and the elastic piece 242 rub against each other and rotate in a staggered manner, at the moment, the flexible opening and closing component 31 drives the rotating wheel piece 241 on the bearing main body 2111 which has reached the maximum opening degree to rotate, and meanwhile, the rotating wheel piece 241 on the bearing main body 2111 which has not reached the maximum opening degree is driven to move until the curtain closing action is completed.

In conclusion, the light-adjusting opening and closing device in the embodiment is applied to the bendable vertical opening and closing curtain, so that the arc-shaped window can be covered, opened and closed and the light-adjusting action are completed, the application problem that the vertical opening and closing curtain is used for the arc-shaped window is solved, and the economic value is high.
