[0045] This embodiment provides an electric curtain, which includes a first curtain (not shown in the figure), a second curtain (not shown in the figure), and an electric track 010 (as Figure 1 shown). Both the first curtain and the second curtain are arranged on the electric track 010, and the electric track 010 can control the first curtain and the second curtain to open or close relative to each other.

[0046] In order to enable the electric curtain to be applicable to places with different widths, please refer to Figure 1 , the electric track 010 of this embodiment includes a first slide rail 100 and a second slide rail 200. The first slide rail 100 and the second slide rail 200 are arranged side by side, and the first slide rail 100 and the second slide rail 200 are slidably connected. The first curtain is slidably arranged on the first slide rail 100, and the second curtain is slidably arranged on the second slide rail 200. In this way, the total length of the electric track 010 can be adjusted by the relative sliding of the first slide rail 100 and the second slide rail 200 to be applicable to places with different widths.

[0047] It should be noted that the sliding connection method of the first slide rail 100 and the second slide rail 200 is similar to the related art and will not be elaborated here.

[0048] It should be understood that in other embodiments, the electric track 010 is an ordinary 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. When assembling the electric track 010 at an installation position such as the ceiling, the installation positions of the first slide rail 100 and the second slide rail 200 can be directly adjusted as needed to make the total length of the electric track 010 meet the requirements.

[0049] Please continue to refer toFigure 1 The electric track 010 of this embodiment includes a first pulley 110, a second pulley 210 and a driving device 300. The first pulley 110 is slidably arranged on the first slide rail 100, and the first curtain is arranged on the first slide rail 100 through the first pulley 110; the second pulley 210 is slidably arranged on the second slide rail 200, and the second curtain is arranged on the second slide rail 200 through the second pulley 210; the driving device 300 can be simultaneously connected to the first pulley 110 and the second pulley 210 in transmission to drive the first pulley 110 to slide along the first slide rail 100, and drive the second pulley 210 to slide along the second slide rail 200, thereby realizing the opening or closing of the first curtain and the second curtain.

[0050] For further information, please refer to Figure 1 and Figure 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 arranged on the first slide rail 100, and is transmission-connected to the double-sided toothed belt 330, and the double-sided toothed belt 330 is connected to the first pulley 110; the second driving mechanism 320 and the second driving assembly 350 are both arranged on the second slide rail 200, and the second driving mechanism 320 is transmission-connected to the second driving assembly 350, and the second driving mechanism 320 is transmission-connected to the second pulley 210, and the second driving assembly 350 is configured to be transmission-connected or disconnected with the double-sided toothed belt 330; when the second driving assembly 350 is transmission-connected to the double-sided toothed belt 330, the first driving mechanism 310 and the second driving mechanism 320 can synchronously drive the first pulley 110 and the second pulley 210 to move.

[0051] It should be understood that in other embodiments, the second drive component 350 may not be arranged on the second slide rail 200. For example, the second drive component 350 can be independently installed on an installation location such as a ceiling, and can be located on an extension line of the second slide rail 200, so that the second drive component 350 can only be connected to the first drive component 340 and the second drive mechanism 320 at the same time.

[0052] In other embodiments, the first drive component 340 may not be disposed on the first slide rail 100, and it may be independently assembled on an installation location such as a ceiling. It is only necessary to ensure that the first drive component 340 is in transmission connection with the first pulley 110. In other embodiments, the second drive mechanism 320 may not be disposed on the second slide rail 200. It may be independently assembled on an installation location such as a ceiling, and may be located on the extension line of the second slide rail 200. It is only necessary to ensure that the second drive mechanism 320 is in transmission connection with the second drive component 350 and the second pulley 210.

[0053] The electric track 010 of this embodiment can be separated from the double-sided toothed belt 330 through the second driving component 350 to disconnect the transmission connection between the first driving component 340 and the second driving mechanism 320. Therefore, the first sliding carriage 110 and the second sliding carriage 210 can move independently. Furthermore, it is convenient to independently move the first sliding carriage 110 along the first sliding rail 100 to its corresponding initial position and independently move the second sliding carriage 210 along the second sliding rail 200 to its corresponding initial position. After that, the second driving component 350 is moved 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. Then, the driving device 300 can be used to drive the first sliding carriage 110 and the second sliding carriage 210 to move along their respective corresponding sliding rails simultaneously. It can not only synchronously drive the first curtain and the second curtain to open or close through the driving device 300, but also make the first curtain and the second curtain close at the middle position of the electric track 010, improving the user experience.

[0054] Furthermore, when the second driving component 350 is separated from the double-sided toothed belt 330, the second driving component 350 remains in transmission connection with the second driving mechanism 320.

[0055] The electric track 010 of this embodiment can be separated from the double-sided toothed belt 330 through the second driving component 350 to disconnect the transmission connection between the first driving component 340 and the second driving mechanism 320. At this time, the second driving component 350 is still in transmission connection with the first driving mechanism. Since the first driving component 340 and the second driving mechanism 320 are not in transmission connection, the first sliding carriage 110 and the second sliding carriage 210 can move independently. Furthermore, it is convenient to independently move the first sliding carriage 110 along the first sliding rail 100 to its corresponding initial position and independently move the second sliding carriage 210 along the second sliding rail 200 to its corresponding initial position. After that, the second driving component 350 is moved 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. Then, the driving device 300 can be used to drive the first sliding carriage 110 and the second sliding carriage 210 to move along their respective corresponding sliding rails simultaneously. It can not only synchronously drive the first curtain and the second curtain to open or close through the driving device 300, but also make the first curtain and the second curtain close at the middle position of the electric track 010. Since the second driving component 350 is always in transmission connection with the second driving mechanism 320 during the process of disconnection and restoration of the transmission connection between the first driving component 340 and the second driving mechanism 320, it can ensure the stable cooperation between the first driving mechanism 310 and the second driving mechanism 320, ensure the normal opening and closing of the curtain, and improve the user experience.

[0056] 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 arranged 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 arranged on the second pulley 210 is in a fully opened state; it can also be understood that when the first pulley 110 is in the initial position and the second pulley 210 is in the initial position, the distance between the first pulley 110 and the second pulley 210 is the largest along the length extension direction of the electric track 010.

[0057] Please refer to Figure 2 The second slide rail 200 of this embodiment includes a slide rail body 220 and a mounting member 221 disposed on the slide rail body 220. The second drive assembly 350 is movably disposed in the mounting member 221 so that the second drive assembly 350 can be connected or separated from the double-sided toothed belt 330. In this way, the mounting member 221 can be used to protect the second drive assembly 350, ensure the stability of the movement of the second drive assembly 350 relative to the second slide rail 200, and further ensure that the second drive assembly 350 can stably move to be connected or separated from the double-sided toothed belt 330, and ensure that the second drive assembly 350 is reliably connected to the second drive mechanism 320.

[0058] It should be understood that in other embodiments, the second slide rail 200 only includes the slide rail body 220, and the mounting member 221 can be independently set at an installation location such as a ceiling, and can be located on an extension line of the slide rail body 220 without being connected to the slide rail body 220, which is not specifically limited here.

[0059] It should be noted that the mounting member 221 may be a mounting member, a mounting plate, a bracket, etc., which is not specifically limited here.

[0060] Please refer to Figure 3 and Figure 4 The electric track 010 further includes a support frame 400, which is rotatably disposed on the mounting member 221, and the second drive assembly 350 is disposed on the support frame 400; when the support frame 400 rotates relative to the mounting member 221, the second drive assembly 350 can be driven to connect or disconnect with the double-sided toothed wheel. In this way, the second drive assembly 350 can be driven to connect or disconnect with the double-sided toothed belt 330 by simply rotating the support frame 400, which is simple to operate.

[0061] Further, the support frame 400 includes a support frame body 410 and a driving member 420. The driving member 420 is connected to the support frame body 410, and the support frame body 410 is rotatably disposed on the mounting member 221; the second driving assembly 350 is disposed on the support frame body 410; the mounting member 221 is provided with an opening 222, and the driving member 420 passes through the opening 222 and extends out of the mounting member 221, and the driving member 420 can swing within the opening 222 to drive the support frame body 410 to rotate relative to the mounting member 221, thereby driving the second driving assembly 350 to be in driving connection or separation with the double-sided toothed belt 330. In this way, it is convenient for the user to apply force to the driving member 420 to swing it, which can drive the support frame body 410 to rotate relative to the mounting member 221, and then drive the second driving assembly 350 to move relative to the mounting member 221 and be in driving connection or separation with the double-sided toothed belt 330, ensuring the convenience of operation.

[0062] Furthermore, a first rotating shaft 224 is fixedly connected inside the mounting member 221, and the support frame body 410 is rotatably sleeved on the first rotating shaft 224, which can reliably rotatably connect the support frame body 410 and the mounting member 221. In other embodiments, the support frame 400 is provided with a first rotating shaft 224, and the mounting member 221 is rotatably connected to the first rotating shaft 224.

[0063] It should be noted that the driving member 420 can be a driving plate or a driving rod connected to the support frame body 410, and no specific limitation is made here.

[0064] It should also be noted that the connection manner between the driving member 420 and the support frame body 410 can be integrally formed, welded or bonded, etc., and no specific limitation is made here.

[0065] In other embodiments, the support frame 400 is rotatably connected to the mounting member 221 through an arc-shaped slide rail; specifically, the support frame body 410 is provided with an arc-shaped fixed slide rail, and the mounting member 221 is provided with an arc-shaped moving slide rail, and the arc-shaped moving slide rail is in sliding fit with the arc-shaped fixed slide rail, or one of the support frame 400 and the mounting member 221 is provided with an arc-shaped slide rail, and the other is provided with an arc-shaped slider, and the rotation connection is realized through the sliding fit of the arc-shaped slide rail and the slider.

[0066] Please refer to Figure 3, the second driving mechanism 320 includes a third driving assembly 321 disposed on the support frame 400. When the second driving assembly 350 is separated from the double-sided toothed belt 330, the second driving assembly 350 remains in driving connection with the third driving assembly 321. In this way, through the separation and driving connection of the second driving assembly 350 and the double-sided toothed belt 330, during the process of disconnecting and then restoring the driving connection between the first driving assembly 340 and the second driving mechanism 320, the second driving assembly 350 is always in driving connection with the third driving assembly 321. Therefore, it can ensure the stable cooperation between the first driving mechanism 310 and the second driving mechanism 320, ensure the normal opening and closing of the curtain, and improve the user experience.

[0067] Please refer to Figure 3 , Figure 4 and Figure 5 , in this embodiment, the second driving assembly 350 includes a first gear 351 and a second gear 352, and the first gear 351 and the second gear 352 are coaxially and fixedly connected; the third driving assembly 321 is disposed on the support frame body 410; the third driving assembly 321 includes a third gear 322 and a fourth gear 323 that are coaxially and fixedly connected. The rotation axis of the third gear 322 coincides with the rotation axis of the support frame 400, and the second gear 352 meshes with the fourth gear 323; when the support frame 400 rotates relative to the mounting member 221, the first gear 351 can mesh with or be separated from the double-sided toothed belt 330, and the second gear 352 always meshes with the fourth gear 323. In this way, when the support frame 400 rotates relative to the mounting member 221, the first gear 351 and the second gear 352 can move synchronously with the support frame 400, so that the first gear 351 can mesh with or be separated from the double-sided toothed belt 330. When the first gear 351 meshes with the double-sided toothed belt 330, the second driving assembly 350 is in driving connection with the double-sided toothed belt 330; moreover, when the support frame 400 rotates relative to the mounting member 221 and drives the first gear 351 and the second gear 352 to rotate synchronously around the rotation axis of the support frame 400, since the second gear 352 meshes with the fourth gear 323, the third gear 322 and the fourth gear 323 can rotate synchronously and coaxially with the support frame 400, thereby avoiding the interference of the third gear 322 and the fourth gear 323 with the movement of the support frame 400 and the second driving assembly 350.

[0068] It should be noted that during the rotation of the support frame 400 around the first rotating shaft 224, the second gear 352 and the fourth gear 323 always remain in a meshing state. In this way, when the first gear 351 is meshed with the double-sided toothed belt 330, it can ensure that the first drive component 340 is reliably connected to the second drive mechanism 320 through the second drive component 350, thereby ensuring that the drive device 300 can reliably drive the first pulley 110 and the second pulley 210 at the same time, that is, after the first drive component 340 and the second drive mechanism 320 are disconnected from the second drive mechanism 320 through the second drive component 350 and then restored, the stability of the transmission connection between the first drive component 340 and the second drive mechanism 320 can be ensured, thereby ensuring normal driving of the curtains to open and close, thereby improving the user experience.

[0069] It should be understood that in other embodiments, the rotation axis of the third gear 322 and the rotation axis of the support frame 400 are spaced apart from each other, for example, the third gear 322 and the support frame 400 are independently provided with rotation axes.

[0070] Please refer to 3 and Figure 4 Optionally, the electric track 010 further includes a bracket cover 440 and a mounting cover 225, and the bracket cover 440 is engaged with the support frame 400, so that the first gear 351, the second gear 352, the third gear 322 and the fourth gear 323 are arranged between the bracket cover 440 and the support frame 400, thereby ensuring the stability of the structure between the first gear 351, the second gear 352, the third gear 322 and the fourth gear 323, reducing the first gear 351, the second gear 352, the third gear 322 and the fourth gear 323. 23 is subject to interference and collision problems; the mounting cover 225 is buckled with the mounting part 221, so that at least part of the bracket cover 440, part of the support frame 400, the first gear 351, the second gear 352, the third gear 322 and the fourth gear 323 are all arranged between the mounting part 221 and the mounting cover 225, thereby ensuring that at least part of the bracket cover 440, part of the support frame 400, the first gear 351, the second gear 352, the third gear 322 and the fourth gear 323 are subject to interference and collision problems.

[0071] Further, the bracket cover 440 includes a bracket cover body 441 and an extension portion 442 connected to the bracket cover body 441, the bracket cover body 441 and the support frame body 410 are buckled, and the first gear 351, the second gear 352, the third gear 322 and the fourth gear 323 are arranged between the bracket cover body 441 and the support frame body 410, and the extension portion 442 extends out of the opening 222 and is arranged side by side with the driving member 420. When the second driving assembly 350 needs to be separated from the double-sided toothed belt 330, force can be applied to the driving member 420 and the extension portion 442 at the same time to drive the support frame 400 to rotate reliably.

[0072] Optionally, the extension part 442 is fixedly connected to the driving part 420 so that when the supporting frame 400 is driven to rotate by applying a force through at least one of the extension part 442 and the driving part 420, the extension part 442 and the driving part 420 can move synchronously, ensuring the reliability of the rotation of the supporting frame 400 and also improving the problem of pinching caused by the misalignment between the extension part 442 and the driving part 420. Further, the fixed connection manner between the extension part 442 and the driving part 420 can be selected as needed. For example, the extension part 442 extends to the outside of the driving part 420 in a sleeved manner, or the extension part 442 is bonded or clamped to the driving part 420, or the extension part 442 and the driving part 420 are connected by fasteners such as screws, etc., which are not specifically limited herein.

[0073] Of course, in some embodiments, the bracket cover body 441 and the supporting frame body 410 can be fixedly connected. For example, they are clamped or connected by fasteners such as screws, and the extension part 442 and the driving part 420 can be integrally formed, and the integrally formed part of the two can be fixedly connected to any one of the bracket cover body 441 and the supporting frame body 410.

[0074] Optionally, please refer to Figure 4 and Figure 6 , the mounting part cover 225 is connected with a second rotating shaft 226. When the mounting part cover 225 is buckled with the mounting part 221, the second rotating shaft 226 is inserted into the bracket cover body 441 and cooperates with the first rotating shaft 224. Further, the second rotating shaft 226 can be sleeved, threadedly connected, clamped, abutted, etc. with the first rotating shaft 224, that is, the first rotating shaft 224 and the second rotating shaft 226 are connected to form the rotating shaft of the third gear 322 and the rotating shaft of the supporting frame 400, which are not specifically limited herein. In this way, it can ensure that the supporting frame 400 rotates more stably. At the same time, the operation is convenient, and the production and installation time are saved.

[0075] Please refer to Figure 5 and Figure 7, in this embodiment, the first driving assembly 340 includes a fifth gear 341 and a sixth gear 342. The fifth gear 341 and the sixth gear 342 are respectively rotatably arranged at two ends of the first slide rail 100, and the double-sided toothed belt 330 is jointly tensioned by the fifth gear 341 and the sixth gear 342. The second driving mechanism 320 further includes a seventh gear 324, a transmission belt 325 and a motor (not shown in the figure). The mounting member 221 is connected to one end of the slide rail body 220. The seventh gear 324 is arranged at the other end of the slide rail body 220. The transmission belt 325 is jointly tensioned by the third gear 322 and the seventh gear 324. The second trolley 210 is connected to the transmission belt 325, and the output shaft of the motor is in transmission connection with the seventh gear 324. In this way, when the first gear 351 meshes with the double-sided toothed belt 330, the output shaft of the motor drives the seventh gear 324 to rotate, which can drive the transmission belt 325 to drive the second trolley 210 to move along the length direction of the slide rail body 220. And the transmission belt 325 drives the third gear 322 and the fourth gear 323 to rotate synchronously, so as to drive the second gear 352 and the first gear 351 to rotate synchronously through the fourth gear 323. Furthermore, the first gear 351 is used to drive the double-sided toothed belt 330 to move, and the double-sided toothed belt 330 is used to drive the first trolley 110 to move along the length direction of the first slide rail 100, so as to drive the driving device 300 to be able to synchronously drive the first curtain arranged on the first trolley 110 and the second curtain arranged on the second trolley 210 to move synchronously, so as to realize the opening or closing of the curtain.

[0076] It should be connected. In other embodiments, the output shaft of the motor can be in transmission connection with other gears such as the fifth gear 341 or the sixth gear 342, and no specific limitation is made here.

[0077] It should be noted that the transmission belt 325 can be a single-sided toothed belt, so as to facilitate the reliable tensioning of the transmission belt 325 on the third gear 322 and the seventh gear 324.

[0078] Optionally, please refer to Figure 8 , in order to facilitate the independent movement of the first driving assembly 340 and the second driving mechanism 320, that is, in order to ensure that when the second driving assembly 350 is separated from the double-sided toothed belt 330, it is convenient to independently drive the first trolley 110 and the second trolley 210 to move to the initial positions respectively, the electric track 010 further includes a locking assembly. The locking assembly is configured to cooperate with the support frame 400 to lock the support frame at a position where the second driving assembly 350 is separated from the double-sided toothed belt 330; wherein, the locking assembly can be realized by means of plugging, clamping, screwing, etc.

[0079] The locking component can be a plug-in member 510. When the second driving component 350 is separated from the double-sided toothed belt 330, the plug-in member 510 is used to lock the position of the second driving component 350, so that the second driving component 350 is maintained at a position separated from the double-sided toothed belt 330, which is convenient for the user to move the first pulley 110 and the second pulley 210 to their respective corresponding initial positions.

[0080] Further, the mounting member 221 is provided with a first hole 511, the mounting member cover 225 is provided with a second hole 512, the support frame 400 is provided with a third hole 513, and the bracket cover body 441 is provided with a fourth hole 514. When the second driving component 350 is separated from the double-sided toothed belt 330, the plug-in member 510 is simultaneously inserted into the first hole 511, the second hole 512, the third hole 513 and the fourth hole 514, so as to lock the position of the second driving component 350, so that the second driving component 350 is maintained at a position separated from the double-sided toothed belt 330.

[0081] It should be noted that the plug-in member 510 can be a screw, a screwdriver, a plug post, etc., and no specific limitation is made here.

[0082] The structure of the double-sided toothed belt 330 can be selected according to needs. Please refer to Figure 9 In this embodiment, the double-sided toothed belt 330 includes a steel wire 331 and two layers of nylon sand layers 332. The steel wire 331 is disposed between the two layers of nylon sand layers 332, and the steel wire 331 extends along the length extension direction of the double-sided toothed belt 330. In this way, the strength of the double-sided toothed belt 330 can be improved by using the steel wire 331, and the lightness and toughness of the double-sided toothed belt 330 can be ensured by using the surface nylon sand layer 332.

[0083] Further, the double-sided toothed belt 330 further includes a soft glue filling 333. The soft glue filling 333 is disposed between the two layers of nylon sand layers 332 and can cover the steel wire 331; the soft glue filling 333 can protect the steel wire 331 and also ensure the strength of the double-sided toothed belt 330.

[0084] It should be noted that the number of the steel wires 331 can be selected according to needs, for example: one, two, three, seven, etc., and no specific limitation is made here. Further, when the number of the steel wires 331 is greater than or equal to two, the multiple steel wires 331 are distributed along the width extension direction of the double-sided toothed belt 330.

[0085] In order to adjust the total length of the electric track 010, please refer to Figure 3 and Figure 4, to ensure that the second drive assembly 350 is reliably connected to the double-sided toothed belt 330, the electric track 010 of this embodiment includes an elastic member 500, which is arranged between the support frame 400 and the mounting member 221, and the elastic member 500 is configured to make the support frame 400 always have a tendency to rotate to make the second drive assembly 350 connected to the double-sided toothed belt 330. In this way, after the total length of the electric track 010 is adjusted and the electric curtain is assembled, it can be ensured that the second drive assembly 350 is reliably connected to the double-sided toothed belt 330, and then it can be ensured that the drive device 300 can reliably drive the first curtain and the second curtain to open or close. Of course, in other embodiments, the elastic member 500 may not be provided, and the support frame 400 can be manually reset.

[0086] Furthermore, the elastic member 500 of this embodiment is disposed between the driving member 420 and the mounting member 221 , so as to utilize the elastic member 500 to ensure reliable transmission connection between the second driving assembly 350 and the double-sided toothed belt 330 .

[0087] It should be noted that, through the provision of the elastic member 500, when the user manually pulls the driving member 420, the elastic effect of the elastic member 500 can be overcome to separate the second driving component 350 from the double-sided toothed belt 330, so as to move the first pulley 110 and the second pulley 210 to their respective corresponding initial positions separately, and then the external force acting on the driving member 420 can be canceled, so that the driving member 420 drives the support frame body 410 to rotate under the elastic action of the elastic member 500 until the second driving component 350 is connected to the double-sided toothed belt 330 for transmission, thereby ensuring the reliability of the second driving component 350 being restored to the transmission connection with the double-sided toothed belt 330 after the positions of the first pulley 110 and the second pulley 210 are adjusted.

[0088] Please continue to refer to Figure 3 and Figure 4 In this embodiment, the support frame 400 is provided with a first limiting portion 430. Specifically, the driving member 420 is provided with a first limiting portion 430, and the first limiting portion 430 is located in the mounting member 221; the first limiting portion 430 cooperates with the first end of the elastic member 500 to limit the movement direction of the elastic member 500; in this way, it can be ensured that under the elastic action of the elastic member 500, the second driving component 350 can be reliably connected to the double-sided toothed belt 330.

[0089] Furthermore, the mounting member 221 is provided with a second limiting portion 223, which cooperates with the second end of the elastic member 500 to limit the movement direction of the elastic member 500; in this way, it can be ensured that under the elastic action of the elastic member 500, the second drive assembly 350 can be reliably connected to the double-sided toothed belt 330.

[0090] Of course, in other embodiments, it can be selectively disposed on one of the first limiting portion 430 and the second limiting portion 223, or neither the first limiting portion 430 nor the second limiting portion 223 is provided; no specific limitation is made here.

[0091] The first limiting portion 430 and the second limiting portion 223 can be selected as needed. In this embodiment, the first limiting portion 430 is the first limiting groove provided on the driving member 420, and the second limiting portion 223 is the second limiting groove provided on the inner wall of the mounting member 221. The two ends of the elastic member 500 are respectively inserted into the first limiting groove and the second limiting groove; in this way, not only can the movement direction of the elastic member 500 be restricted by the first limiting groove and the second limiting groove, but also the reliability of the elastic member 500 disposed on the driving member 420 and the mounting member 221 can be ensured, and the assembly of the elastic member 500 is also facilitated.

[0092] Of course, in other embodiments, the first limiting portion 430 and the second limiting portion 223 can also be limiting posts provided on the driving member 420 and the mounting member 221 respectively, and the two ends of the elastic member 500 can be respectively sleeved on the two limiting posts.

[0093] In other embodiments, the two ends of the elastic member 500 can also be respectively fixed to the driving member 420 and the mounting member 221 through fasteners such as bolts or screws.

[0094] The elastic member 500 can be selected as needed. In this embodiment, the elastic member 500 is a spring. In other embodiments, the elastic member 500 can also be a torsion spring or an elastic rubber sleeve, etc., and no specific limitation is made here.

[0095] Optionally, the driving device 300 further includes a locking assembly configured to cooperate with the support frame 400 to lock the support frame 400 at a position where the second driving assembly 350 is in driving connection with the double-sided toothed belt 330.

[0096] Further, the locking assembly includes fasteners such as screws or bolts. When the second driving assembly 350 is in driving connection with the double-sided toothed belt 330, the fasteners are simultaneously connected to the support frame 400 and the mounting member 221 to lock the position of the support frame 400. In other embodiments, the locking assembly includes a convex tooth and a groove in a snap-fit relationship, one of the convex tooth and the groove is provided on the support frame 400, and the other is provided on the mounting member. When the second driving assembly 350 is in driving connection with the double-sided toothed belt 330, the convex tooth is snapped into the groove to lock the position of the support frame 400.

[0097] The assembly and use process of the electric curtain of this embodiment includes: making the first slide rail 100 and the second slide rail 200 slide relative to each other to adjust the total length of the electric track 010; after the total length of the electric track 010 is adjusted, applying force to the driving member 420 to make the support frame body 410 rotate around the first rotating shaft 224, so that the first gear 351 of the second driving assembly 350 provided on the support frame body 410 is separated from the double-sided toothed belt 330; sliding the first pulley 110 along the length extension direction of the first slide rail 100 so that the first pulley 110 moves to the initial position, and sliding the second pulley 210 along the length extension direction of the second slide rail 200 so that the second pulley 210 moves to the initial position; canceling the external force applied to the driving member 420, the driving member 420 is reset under the elastic action of the elastic member 500, and at the same time, the support frame body 410 rotates in the opposite direction around the first rotating shaft 224, and the first gear 351 of the second driving assembly 350 provided on the support frame body 410 is meshed with the double-sided toothed belt 330.

[0098] To summarize, the electric track 010 of the electric curtain of the present embodiment can separate the second drive component 350 from the double-sided toothed belt 330. At this time, the first drive component 340 and the second drive mechanism 320 are not connected in transmission, and the first pulley 110 and the second pulley 210 can move independently, thereby facilitating the independent movement of the first pulley 110 along the first slide rail 100 to its corresponding initial position, and independently moving the second pulley 210 along the second slide rail 200 to its corresponding initial position; then the second drive component 350 is moved relative to the second slide rail 200, so that the second drive component 350 is connected in transmission with the double-sided toothed belt 330. At this time, the first drive component 340 is connected in transmission with the second drive mechanism 320, and the first pulley 110 and the second pulley 210 can be simultaneously driven by the drive device 300 to move along their respective corresponding slide rails, so that the curtain can be closed in the middle position, thereby improving the user experience.
