DETAILED DESCRIPTIONS OF EMBODIMENTS

[0031] The technical solutions of the present invention will be fully and clearly described below in combination with the accompanying drawings involved in the embodiments of the present invention. Apparently, these embodiments described herein are merely some of the embodiments of the present invention rather than all embodiments. Other embodiments obtained by those skilled in the art based on these embodiments without paying creative work will fall within the scope of protection of the present invention.

Embodiment One

[0032] FIGS. 1, 2 and 3 show structural schematic diagrams of a telescopic electric curtain guiderail according to a first embodiment of the present invention. The telescopic electric curtain guiderail 100 comprises, for example, a first guiderail piece 10, a second guiderail piece 20, and an adjusting mechanism (not shown). A hollow telescopic receiving cavity 14 is disposed in the first guiderail piece 10, at a side of which a first curtain guiderail 15 is disposed; the second guiderail piece 20 may be sleeved into the telescopic receiving cavity 14 to move along a length direction of the first guiderail piece 10 in the telescopic receiving cavity 14, and a second curtain guiderail 24 capable of combining with the first curtain guiderail 15 is disposed on the second guiderail piece 20; the adjusting mechanism is capable of controlling a sleeving length between the first guiderail piece 10 and the second guiderail piece 20.

[0033] Specifically, the adjusting mechanism comprises an adjusting piece 30 and a wire spool 40. The adjusting piece 30 is wound on the wire spool 40, so that the wire spool 40 performs wire take-up or release for the adjusting piece 30 through rotation, thereby controlling the sleeving length between the first guiderail piece 10 and the second guiderail piece 20. For example, the adjusting piece 30 may be a rope, for example, a wire rope or a nylon rope.

[0034] Preferably, the adjusting mechanism further comprises: a first rotary piece 11 and a second rotary piece 21. The first rotary piece 11 is disposed at a side of the first guiderail piece 10 away from the second guiderail piece 20; the second rotary piece 21 is disposed at a side of the second guiderail piece 20 away from the first guiderail piece 10; the adjusting piece is wound on the first rotary piece 11 and the second rotary piece 21.

[0035] For example, a length of the telescopic electric curtain guiderail 100 is greater than a length required for mounting, the wire spool 40 may take up the adjusting piece 30, so that the first rotary piece 11 rotate clockwise and the second rotary piece 21 rotate counterclockwise at the same time. In this way, the first guiderail piece 10 and the second guiderail piece 20 move toward the second rotary piece 21 and the first rotary piece 11 respectively, so as to shorten the length of the adjusting piece 30 and increase the sleeving length until the length of the telescopic electric curtain guiderail 100 equals the mounting-required length. When the length of the telescopic electric curtain guiderail 100 is smaller than the mounting-required length, the telescopic electric curtain guiderail 100 may work in the reverse manner, which will not be repeated herein.

[0036] Preferably, as shown in FIG. 4, the wire spool 40 comprises a first wire winding wheel 41 and a second wire winding wheel 42. The first wire winding wheel 41 is disposed at an end of the first guiderail piece 10 away from the first rotary piece 11; the second wire winding wheel 42 is disposed on the first guiderail piece 10 and located between the first wire winding wheel 41 and the first rotary piece 11.

[0037] As the first preferred solution, the first wire winding wheel 41 and the second wire winding wheel 42 may take up wire at the same time to shorten the length of the adjusting piece 30, and correspondingly, the first wire winding wheel 41 and the second wire winding wheel 42 may release wire at the same time to lengthen the length of the adjusting piece 30. In this way, the sleeving length can be increased or decreased correspondingly, thus realizing telescopic cooperation between the first guiderail piece 10 and the second guiderail piece 20. Therefore, the first wire winding wheel 41 and the second wire winding wheel 42 can perform wire take-up or release to perform telescopic control at the same time, so as to quickly adjust the length of the telescopic electric curtain guiderail 100.

[0038] Of course, as the second optional solution, the first wire winding wheel 41 and the second wire winding wheel 42 may also perform telescopic cooperation between the first guiderail piece 10 and the second guiderail piece 20 in another manner. For example, the first wire winding wheel 41 releases wire to increase the length of the adjusting piece 30 while the second wire winding wheel 42 takes up wire to shorten the length of the adjusting piece. If the release speed of the first wire winding wheel 41 is greater than the take-up speed of the second wire winding wheel 42, the length of the adjusting piece 30 will be increased. At this time, the sleeving length will be reduced, and the length of the telescopic electric curtain guiderail 100 will be extended and otherwise the length of the telescopic electric curtain guiderail 100 will be shortened.

[0039] Further, as a third optional solution, the first wire winding wheel 41 may perform wire take-up or release to reduce or increase the length of the adjusting piece 30 while the second wire winding wheel 42 keeps stationary. At this time, the first guiderail piece 10 corresponding to the first wire winding wheel 41 may be controlled to slide relative to the second guiderail piece 20 so as to increase or reduce the sleeving length. In this case, the telescopic operation of the telescopic electric curtain guiderail 100 may be realized with the second guiderail piece 20 stationary. Correspondingly, the second wire winding wheel 42 may perform wire take-up or release to reduce or increase the length of the adjusting piece 30 while the first wire winding wheel 41 keeps stationary. In this case, the telescopic operation of the telescopic electric curtain guiderail 100 may be realized with the first guiderail piece 10 stationary.

[0040] In implementation of the above first preferred solution, when the telescopic electric curtain guiderail 100 is to be extended, the first wire winding wheel 41 and the second wire winding wheel 42 may be operated manually to enable them to perform wire release at the same time; and then the first guiderail piece 10 and the second guiderail piece 20 are pulled apart manually to tension the adjusting piece 30 between the first rotary piece 11 and the second rotary piece 21, and then the relative positions of the first guiderail piece 10 and the second guiderail piece 20 are fixed. In this way, the telescopic electric curtain guiderail 100 can be extended.

[0041] Correspondingly, when the telescopic electric curtain guiderail 100 is to be shortened, the first guiderail piece 10 and the second guiderail piece 20 may be slid relatively manually to increase the sleeving length, and then the first wire winding wheel 41 and the second wire winding wheel 42 are manually operated to perform wire take-up simultaneously so as to tension the adjusting piece 30 between the first rotary piece 11 and the second rotary piece 21, and then the relative positions of the first guiderail piece 10 and the second guiderail piece 20 are fixed. In this way, the telescopic electric curtain guiderail 100 can be shortened.

[0042] Likewise, in the implementation of the second optional solution or the third optional solution, the implementation manner identical to the above first preferred solution may be adopted to complete the extension and shortening of the telescopic electric curtain guiderail 100.

[0043] For another example, the wire spool 40 may comprise one wire winding wheel. The opposing ends of the adjusting piece 30 may be wound onto the wire winding wheel in the same direction respectively. Thus, when the wire winding wheel rotates, the adjusting piece 30 may be taken up or released so as to control the length of the adjusting piece 30.

[0044] Preferably, as shown in FIG. 5, one end of the adjusting piece 30 is fixedly connected to an end of the first guiderail piece 10 away from the first rotary piece 11, and the opposing other end of the adjusting piece 30 is wound onto the first rotary piece 11 and the second rotary piece 21 in sequence and located at an end of the second guiderail piece 20 away from the second rotary piece 21.

[0045] Further, the wire spool 40 may further be disposed at an end of the second guiderail piece 20 away from the second rotary piece 21 for the other end of the adjusting piece 30 to be wound on; the wire spool 40 performs wire release or take-up for the adjusting piece 30 to increase or reduce the length of the adjusting piece 30, so as to correspondingly reduce or increase the sleeving length.

[0046] Preferably, as shown in FIG. 6, the adjusting piece 30 may comprise, for example, an adjusting toothed belt 32 and an adjusting rope 31 connected to the adjusting toothed belt 32. The first rotary piece 11 is a gear matched with the adjusting toothed belt 32, and the adjusting toothed belt 32 is wound on the first rotary piece 11; the adjusting rope 31 is wound on the second rotary piece 21. In this way, the transmission efficiency of the adjusting piece 30 is improved and the energy loss in transmission is reduced. For example, the adjusting toothed belt 32 may be a synchronous belt, for example, a rubber synchronous belt or a polyurethane synchronous belt.

[0047] Preferably, as shown in FIGS. 7, 8 and 9, the first curtain guiderail 15 may comprise, for example, a first moving opening 12 opened on the first guiderail piece 10, and two first rolling limiting pieces 13 disposed at both sides of the first moving opening 12 respectively; the second curtain guiderail 24 may comprise, for example, a second moving opening 22 opened on the second guiderail piece 20, and two second rolling limiting pieces 23 disposed at both sides of the second moving opening 22 respectively. An opening width of the second moving opening 22 is greater than an opening width of the first moving opening 12. When the second guiderail piece 20 is sleeved into the first guiderail piece 10, the two first rolling limiting pieces 13 are located between the two second rolling limiting pieces 23. For example, the first guiderail piece 10 and the second guiderail piece 20 may be made of plastic or metal material.

[0048] Preferably, as shown in FIG. 10, the telescopic electric curtain guiderail 100 may further comprise, for example, a first mounting portion 60 and a second mounting portion 70. The first mounting portion 60 is provided internally with the first rotary piece 11 and connected with the first guiderail piece 10; the second mounting portion 70 is provided internally with the second rotary piece 21 and connected with the second guiderail piece 20.

[0049] Preferably, as shown in FIG. 11, the telescopic electric curtain guiderail 100 may further comprise, for example, a fixing piece 50, where the fixing piece 50 is clamped between the first guiderail piece 10 and the second guiderail piece 20 to fix the sleeving length. For example, the fixing piece 50 may have different sizes to match with a spacing between the first guiderail piece 10 and the second guiderail piece 20.

Embodiment Two

[0050] FIG. 12 is a structural schematic diagram of a curtain 200 according to a second embodiment of the present invention. The curtain 200 may comprise, for example, the telescopic electric curtain guiderail 100, a plurality of rolling pieces (not shown) and a blocking piece 240. The plurality of rolling pieces may be rollingly disposed on the first curtain guiderail 15 and the second curtain guiderail 24; the blocking piece 240 may be connected to the plurality of rolling pieces. For example, the blocking piece 240 may be made of pure cotton, linen, terylene or silk, or may be made by mixed weaving of the above materials.

[0051] Preferably, at least one in the plurality of rolling pieces disposed on the first curtain guiderail 15 is a first rolling piece 210 and the remaining rolling pieces are second rolling pieces 220; the blocking piece 240 comprises a first blocking piece 241 connected to the first rolling piece 210 and a second blocking piece 242 connected to the second rolling piece 220; the curtain 200 further comprises, for example, a blocking piece separating portion 230, disposed on the second curtain guiderail 24 or the first curtain guiderail 15 to separate the first rolling piece 210 from the second rolling piece 220.

[0052] For example, five first rolling pieces 210 and a blocking piece separating portion 230 are disposed on the first curtain guiderail 15, and the first blocking piece 241 is hung to the five first rolling pieces 210 and the blocking piece separating portion 230; five second rolling pieces 220 and another blocking piece separating portion 230 are disposed on the second curtain guiderail 24, and the second blocking piece 242 is hung on the five second rolling pieces 220 and the blocking piece separating portion 230. Thus, an opening-closing type curtain is formed.

[0053] The above two blocking piece separating portions 230 may be controlled to open or close the corresponding first blocking piece 241 and second blocking piece 242.

[0054] Finally, it should be noted that the above embodiments are only used to describe the technical solutions of the present invention rather than limit the present invention.
