Thus, the total length of the electric rail 010 can be adjusted by the relative sliding of the first slide rail 100 and the second slide rail 200, so as to be suitable for places with different widths.

It should be noted that the sliding connection manner of the first slide rail 100 and the second slide rail 200 is similar to that of the related art, and is not described herein again.

It should be understood that, in other embodiments, the power track 010 is a general track with an unadjustable length, that is, the first slide rail 100 and the second slide rail 200 do not need to be slidably connected, and when the power track 010 is mounted at a mounting position such as a ceiling, the mounting positions of the first slide rail 100 and the second slide rail 200 can be directly adjusted as required, so that the overall length of the power track 010 meets the requirement.

Referring to fig. 1, the electric track 010 of the embodiment includes a first pulley 110, a second pulley 210 and a driving device 300, the first pulley 110 is slidably disposed on the first sliding rail 100, and the first curtain is disposed on the first sliding rail 100 through the first pulley 110; the second pulley 210 is slidably disposed on the second sliding rail 200, and the second curtain is disposed on the second sliding rail 200 through the second pulley 210; the driving device 300 can be simultaneously in transmission connection with the first pulley 110 and the second pulley 210 to drive the first pulley 110 to slide along the first sliding rail 100 and the second pulley 210 to slide along the second sliding rail 200, so as to open or close the first curtain and the second curtain.

Further, referring to fig. 1 and fig. 2, the driving device 300 includes a first driving mechanism 310 and a second driving mechanism 320, wherein the first driving mechanism 310 includes a double-sided toothed belt 330, a first driving assembly 340 and a second driving assembly 350, the first driving assembly 340 is disposed on the first slide rail 100 and is in transmission connection with the double-sided toothed belt 330, and the double-sided toothed belt 330 is connected with the first pulley 110; the second driving mechanism 320 and the second driving assembly 350 are disposed on the second slide rail 200, the second driving mechanism 320 is in transmission connection with the second driving assembly 350, the second driving mechanism 320 is in transmission connection with the second pulley 210, and the second driving assembly 350 is configured to be in transmission connection with or separated from the double-sided toothed belt 330; in the case that the second driving assembly 350 is in transmission connection with the double-sided toothed belt 330, the first driving mechanism 310 and the second driving mechanism 320 can synchronously drive the first sled 110 and the second sled 210 to move.

It should be appreciated that in other embodiments, the second driving assembly 350 may not be disposed on the second sliding rail 200, for example, the second driving assembly 350 may be independently installed on a ceiling or other installation position, and may be located on an extension line of the second sliding rail 200, so that the second driving assembly 350 can be in transmission connection with the first driving assembly 340 and the second driving mechanism 320 at the same time.

In other embodiments, the first driving assembly 340 may not be disposed on the first sliding rail 100, and it may be independently mounted on a mounting location such as a ceiling, and it is only necessary to ensure that the first driving assembly 340 is in transmission connection with the first pulley 110; in other embodiments, the second driving mechanism 320 may not be disposed on the second sliding rail 200, and may be independently mounted on a ceiling or other installation location, and may be located on an extension line of the second sliding rail 200, only by ensuring that the second driving mechanism 320 is in transmission connection with the second driving assembly 350 and the second pulley 210.

The electric rail 010 of this embodiment can separate the second driving component 350 from the double-sided toothed belt 330 to disconnect the transmission connection between the first driving component 340 and the second driving mechanism 320, so that the first pulley 110 and the second pulley 210 can move independently, and further, the first pulley 110 can move independently to its corresponding initial position along the first sliding rail 100, and the second pulley 210 can move independently to its corresponding initial position along the second sliding rail 200; then, the second driving assembly 350 moves relative to the second sliding rail 200, so that the second driving assembly 350 is in transmission connection with the double-sided toothed belt 330, at this time, the first driving assembly 340 is in transmission connection with the second driving mechanism 320, that is, the first pulley 110 and the second pulley 210 can be simultaneously driven to move along the respective corresponding sliding rails by the driving device 300, and not only can the first curtain and the second curtain be synchronously driven to open or close by the driving device 300, but also the first curtain and the second curtain can be closed at the middle position of the electric rail 010, thereby improving user experience.

Further, with the second drive assembly 350 separated from the double-sided toothed belt 330, the second drive assembly 350 remains in driving connection with the second drive mechanism 320.

The electric rail 010 of this embodiment can separate the second driving component 350 from the double-sided toothed belt 330 to disconnect the transmission connection between the first driving component 340 and the second driving mechanism 320, and at this time, the second driving component 350 is still in transmission connection with the first driving mechanism, and since the first driving component 340 is not in transmission connection with the second driving mechanism 320, the first pulley 110 and the second pulley 210 can move independently, so as to facilitate independently moving the first pulley 110 to its corresponding initial position along the first sliding rail 100, and independently moving the second pulley 210 to its corresponding initial position along the second sliding rail 200; then, the second driving component 350 moves relative to the second sliding rail 200, so that the second driving component 350 is in transmission connection with the double-sided toothed belt 330, at this time, the first driving component 340 is in transmission connection with the second driving mechanism 320, that is, the first pulley 110 and the second pulley 210 can be simultaneously driven to move along the respective corresponding sliding rails by the driving device 300, and not only can the first curtain and the second curtain be synchronously driven to open or close by the driving device 300, but also the first curtain and the second curtain can be closed at the middle position of the electric rail 010; in the process of disconnecting and recovering the transmission connection between the first driving assembly 340 and the second driving mechanism 320, the second driving assembly 350 is always in transmission connection with the second driving mechanism 320, so that the first driving mechanism 310 and the second driving mechanism 320 can be stably matched, the normal opening and closing of the curtain can be ensured, and the user experience can be improved.

It should be noted that the initial position of the first pulley 110 is the end of the first slide rail 100, and the first curtain disposed on the first pulley 110 is in a fully opened state; the initial position of the second pulley 210 is the end of the second slide rail 200, and the second curtain disposed on the second pulley 210 is in a fully opened state; it can also be understood that when the first block 110 is located at the initial position and the second block 210 is located at the initial position, the distance between the first block 110 and the second block 210 is the largest along the length extension direction of the power track 010.

Referring to fig. 2, the second slide rail 200 of the present embodiment includes a slide rail body 220 and a mounting component 221 disposed on the slide rail body 220, and the second driving component 350 is movably disposed in the mounting component 221, so that the second driving component 350 can be in transmission connection with or separated from the double-sided toothed belt 330. In this way, the mounting member 221 can be used to shield the second driving assembly 350, so as to ensure the stability of the movement of the second driving assembly 350 relative to the second slide rail 200, further ensure that the second driving assembly 350 can be stably moved to be in transmission connection with or separated from the double-sided toothed belt 330, and ensure that the second driving assembly 350 is reliably in transmission connection with the second driving mechanism 320.

It should be understood that in other embodiments, the second slide rail 200 only includes the slide rail body 220, and the mounting part 221 may be independently disposed at a mounting position such as a ceiling, and may be located on an extension line of the slide rail body 220 without being connected to the slide rail body 220, and is not particularly limited herein.

The mounting member 221 may be a mounting member, a mounting plate, a bracket, or the like, and is not particularly limited herein.

Therefore, the second driving assembly 350 can be driven to be in transmission connection with or separated from the double-sided toothed belt 330 only by rotating the supporting frame 400, and the operation is simple.

Further, the supporting frame 400 includes a supporting frame body 410 and a driving member 420, the driving member 420 is connected to the supporting frame body 410, and the supporting frame body 410 is rotatably disposed on the mounting member 221; the second driving assembly 350 is disposed on the supporting frame body 410; the mounting member 221 is provided with an opening 222, the driving member 420 passes through the opening 222 and extends out of the mounting member 221, and the driving member 420 can swing in the opening 222 to drive the supporting frame body 410 to rotate relative to the mounting member 221, so as to drive the second driving assembly 350 to be in transmission connection with or separate from the double-sided toothed belt 330. Therefore, a user can apply force to the driving member 420 to swing the driving member, so as to drive the supporting frame body 410 to rotate relative to the mounting member 221, and further drive the second driving assembly 350 to move relative to the mounting member 221 and to be in transmission connection with or separated from the double-sided toothed belt 330, thereby ensuring convenience in operation.

Furthermore, the first rotating shaft 224 is fixedly connected to the mounting member 221, and the supporting frame body 410 is rotatably sleeved on the first rotating shaft 224, so that the supporting frame body 410 and the mounting member 221 can be reliably and rotatably connected.
