Specifically, the outer diameter of the elastic portion 2142 is slightly larger than the diameter of the accommodating cavity 21411, so that when the elastic portion 2142 is disposed in the accommodating cavity 21411, the elastic portion 2142 and the rotating wheel portion 2141 can form an interference fit, so that the rotating wheel portion 2141 can rotate the elastic portion 2142, and only when the external force is greater than the friction force between the rotating wheel portion 2141 and the elastic portion 2142, the rotating wheel portion 2141 and the elastic portion 2142 can rotate in a staggered manner.

With reference to fig. 14, fig. 14 is an enlarged view of a portion D of fig. 2 according to the first embodiment. Furthermore, the dimming opening and closing mechanism 2 further comprises a plurality of curtain opening limiting assemblies 23. A curtain opening limiting component 23 is arranged between two adjacent bearing components 211, and two ends of the curtain opening limiting component 23 are movably connected with the two adjacent bearing components 211 respectively; the curtain opening limiting component 23 limits the maximum curtain opening degree between two adjacent bearing pieces 211. When the limiting linkage 212 reaches the limit of the rotation stroke and the supporting element 211 reaches the maximum opening degree, the transmission element 221 drives the rotating wheel portion 2141 to rotate, and the rotating wheel portion 2141 and the elastic portion 2142 rotate due to friction. Thus, the maximum opening and closing degree of the two adjacent dimming components 21 is limited by the arrangement of the curtain opening limiting component 23, so that the accurate execution of the curtain opening action is ensured. Specifically, two ends of the curtain opening limiting component 23 are respectively provided with a limiting protrusion 231, and the bearing main body 21111 is provided with a limiting sliding groove 216. The curtain opening limiting component 23 is slidably connected in the limiting sliding grooves 216 of two adjacent bearing main bodies 21111, and the two limiting protrusions 231 are respectively located on the outer sides of the two adjacent bearing main bodies 21111 which are opposite to each other. The limiting sliding grooves 216 slide relative to the curtain opening limiting assembly 23, when two adjacent limiting sliding grooves 216 abut against the limiting protrusions 231 at two opposite ends of the curtain opening limiting assembly 23, the maximum distance between two adjacent bearing main bodies 21111 is reached, that is, the maximum curtain opening degree of two adjacent bearing pieces 211 is limited, the distance between two adjacent bearing pieces 211 is the curtain opening degree, two adjacent dimming assemblies 21 reach the maximum curtain opening degree, and the moving stroke of the bearing pieces 211 of the dimming assembly 21 in this embodiment reaches the maximum curtain opening degree. After the two adjacent carrier parts 211 reach the maximum opening degree, the transmission part 221 continues to rotate to drive the other subsequent carrier parts 211 to move, at this time, the two adjacent carrier parts 211 which have reached the maximum opening degree do not move any more, the elastic part 2142 forms a sleeved relationship with the rotating wheel part 2141 by using the elastic property of the transmission part, when the acting force of the transmission part 221 on the rotating wheel part 2141 is greater than the acting force between the elastic part 2142 and the rotating wheel part 2141, the elastic part 2142 and the rotating wheel part 2141 perform relative friction rotation, at this time, the cooperation of the elastic part 2142 and the rotating wheel part 2141 is approximately a clutch structure, thereby avoiding the damage of the dimming assembly 21.

With reference to fig. 15, fig. 15 is an enlarged view of a portion E of fig. 2 according to the first embodiment. Further, the transmission assembly 22 further includes an opening/closing stopper 224. The number of the opening and closing limiting members 224 is two, the two opening and closing limiting members 224 are respectively disposed on the transmission member 221, and specifically, the two opening and limiting members 224 are respectively disposed on the transmission member 221 connected to the transmission groove 113. The transmission member 221 rotates to drive the two opening/closing position-limiting members 224 to move closer to or away from each other. The curtain closing action of the vertical curtain opening and closing is convenient to be carried out by the opening and closing limiting piece 224. It can be understood that two of the dimming components 21 in the plurality of dimming components 21 are opening and closing points when opening and closing actions are performed, the opening and closing points are generally located at the middle position of the whole vertical opening and closing curtain, and when closing the curtain, the dimming components 21 need to be limited so as to avoid the over-position of the closed curtain. When the curtain closing action is executed, the two opening and closing limiting pieces 224 are close to each other, and when the two opening and closing limiting pieces 224 are abutted against each other, the curtain closing action is executed in place, and the device is prevented from being damaged due to the fact that the curtain closing action is over-positioned due to the limitation of the opening and closing limiting pieces 224. Preferably, the opening/closing stoppers 224 are detachably connected to the driving member 221. The opening/closing position-limiting member 224 in this embodiment is a block with a clamping structure, and a channel for movement of the opening/closing position-limiting member 224 is reserved inside the rail main body 111.

Referring back to fig. 15, further, the light adjusting opening and closing mechanism 2 further includes a magnetic attraction component 24. The magnetic attraction member 24 is located between two dimming components 21 at the opening and closing point among the plurality of dimming components 21. It can be understood that, the two light-adjusting components 21 at the opening and closing point are the opening points of the vertical opening and closing curtain for executing the opening action, after the curtain is closed, the two light-adjusting components 21 at the opening points are adsorbed together through the setting of the magnetic attraction component 24, the state of the closed curtain can be ensured, and in the state of the closed curtain, when the curtain sheet covering the window needs to be adjusted, the transmission component 221 is required to drive the rotating wheel portion 2141 to rotate, the magnetic attraction portion at this time can still ensure that the two light-adjusting components 21 at the opening points are adsorbed together, the state of the closed curtain is maintained, the light-adjusting action in the state of the closed curtain is ensured to be smoothly performed, when the limit linkage 212 reaches the limit of the rotation stroke, the transmission component 221 drives the rotating wheel portion 2131 to move, the acting force of the transmission component 221 is greater than the adsorption force of the magnetic attraction component 24, and the subsequent opening action can be performed. Like this, through the setting of magnetism subassembly 24 of inhaling, when having guaranteed the curtain state that closes of the curtain that opens and shuts perpendicularly, also guaranteed the accuracy of adjusting luminance action and going on under closing the curtain state.

The dimming process in this embodiment is as follows: in a curtain closing state, the driving member 221 drives the rotating wheel portion 2141 to rotate, the rotating wheel portion 2141 drives the elastic portion 2142 to rotate, the first acting end 21421 or the second acting end 21422 of the elastic portion 2142 acts on the shifting plate 212121 to push the driving sleeve 21212 to rotate, the driving sleeve 21212 drives the driving wheel 21213 to rotate, the driving wheel 21213 drives the limiting member 2122 to rotate, and the limiting member 2122 drives the curtain piece on the hook portion 2131 of the curtain piece mounting member 213 to rotate, thereby realizing the dimming of the curtain piece. When the brake block 21221 abuts against the end of the arc-shaped stopper 211132, the rotation stroke is reached, 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 element 2122 is blocked by the arc-shaped limiting element 211132 and the maximum dimming angle is reached, the limiting element 2122 does not rotate any more, the elastic portion 2142 and the rotating wheel portion 2141 do not rotate any more, at this time, the driving element 221 drives the rotating wheel portion 2141 to move, the rotating wheel portion 2141 drives the bearing main body 21111 to slide in the dimming track groove 112, so that the two adjacent bearing main bodies 21111 approach each other, when the two adjacent bearing main bodies 21111 abut against each other, the rotating wheel portion 2141 and the elastic portion 2142 rub against each other and rotate in a staggered manner, at this time, the driving element 221 drives the rotating wheel portion 2141 on the bearing main body 21111 that has already abutted against to rotate, and at the same time, drives the rotating wheel portion 2141 on the bearing main body 21111 that has not yet abutted against to move until the curtain opening action is completed. When the curtain is closed, the transmission member 221 starts to rotate reversely, the transmission member 221 drives the rotating wheel portion 2141 to rotate first, after the brake block 21221 abuts against the other end portion of the arc-shaped limit block 211132, the transmission member 221 drives the rotating wheel portion 2141 to move, so that the two adjacent bearing main bodies 21111 are away from each other, when the two adjacent bearing main bodies 21111 are limited by the curtain opening limit component 23 to reach the maximum curtain opening degree, the rotating wheel portion 2141 and the elastic portion 2142 rub against each other to rotate in a staggered manner, at this time, the transmission member 221 drives the rotating wheel portion 2141 on the bearing main body 21111 which has reached the maximum curtain opening degree to rotate, and at the same time, drives the rotating wheel portion 2141 on the bearing main body 21111 which has not reached the maximum curtain opening degree to move until the curtain closing action is completed.

It can be understood that, in this embodiment, the driving member 221 directly drives the light adjusting assembly 21 to perform the light adjusting operation and the curtain opening and closing operation, and the driving member 221 is flexible and bendable, and under the condition that the driving member 221 is bent, the driving member 221 is not affected to drive the light adjusting assembly 21 to perform the light adjusting operation and the curtain opening and closing operation, so that the curtain sheet of the vertical curtain opening and closing operation in this embodiment can cover the arc-shaped window, and the light adjusting, curtain opening and curtain closing functions can be realized. That is to say, the vertical retractable curtain in this embodiment not only simplifies the light-adjusting retractable structure and saves the cost, but also can be applied to the arc window by using the whole vertical retractable curtain through the cooperation of the light-adjusting assembly 21, the transmission member 221 and the rail main body 11 with the curved rail structure, thereby increasing the application range.
