The present embodiment provides a motorized window treatment that includes a motorized track 010 (shown in fig. 1) and a window covering (not shown), wherein the motorized track 010 can control the opening or closing of the window covering.

Further, the motorized window treatment includes a first window treatment and a second window treatment (not shown), referring to fig. 1, the motorized track 010 includes a first track 100 and a second track 200, the first window treatment is slidably disposed on the first track 100, the second window treatment is slidably disposed on the second track 200, and the first track 100 and the second track 200 are disposed side by side; the first and second shades may be relatively open or closed.

In order to allow the motorized window treatment to be used in various areas having different widths, the first and second rails 100 and 200 of the present embodiment are slidably coupled to each other so that the overall length of the motorized track 010 can be adjusted by relative sliding movement of the first and second rails 100 and 200.

It should be noted that, the sliding connection mode of the first rail 100 and the second rail 200 can be selected according to the needs, for example: the first rail 100 is provided with a sliding groove, and the second rail 200 is slidably engaged with the sliding groove. Of course, in other embodiments, the first rail 100 and the second rail 200 may also be matched by a sliding rail, and are not limited herein.

It should be understood that in other embodiments, the first rail 100 and the second rail 200 may not be slidably connected, but may be separately assembled with the installation site of the ceiling at the time of assembly, and the two may be spliced in a length direction perpendicular to themselves.

With reference to fig. 1, fig. 2 and fig. 3, the electric track 010 of the embodiment further includes a first pulley 110, a second pulley 210 and a transmission device 300, wherein the first pulley 110 is slidably disposed on the first track 100 and is used for disposing a first curtain; the second pulley 210 is rotatably disposed on the second track 200 and is used for disposing a second curtain; the transmission device 300 is in transmission connection with the first pulley 110 and the second pulley 210, and is used for controlling the first pulley 110 to slide along the first track 100 and the second pulley 210 to slide along the second track 200, so as to control the opening or closing of the first curtain and the second curtain.

Further, the transmission device 300 includes a first transmission mechanism 310 and a second transmission mechanism 320, the first transmission mechanism 310 is in transmission connection with the first pulley 110 and is used for driving the first pulley 110 to slide along the length extension direction of the first rail 100; the second transmission mechanism 320 is in transmission connection with the second sled 210 and is used for driving the second sled 210 to slide along the length extension direction of the second track 200. In this way, the first pulley 110 and the second pulley 210 can be reliably driven to move by the first transmission mechanism 310 and the second transmission mechanism 320, so as to open or close the first curtain and the second curtain.

Since the overall length of the motorized track 010 can be adjusted by the relative sliding between the first track 100 and the second track 200, in order to enable the first curtain and the second curtain to be closed at the intermediate position of the motorized track 010 also after the overall length of the motorized track 010 is adjusted; the first transmission mechanism 310 of the present embodiment is movable relative to the second transmission mechanism 320 to be drivingly connected to or disconnected from the second transmission mechanism 320. In this way, after the total length of the motorized track 010 is adjusted, the first transmission mechanism 310 and the second transmission mechanism 320 are separated, so that the first pulley 110 is independently moved to the initial position along the first track 100, the second pulley 210 is independently moved to the initial position along the second track 200, and then the first transmission mechanism 310 and the second transmission mechanism 320 are in transmission connection, so that the first transmission mechanism 310 and the second transmission mechanism 320 in transmission connection with each other are used to simultaneously control the movement of the first pulley 110 and the second pulley 210, and the motorized window shade using the motorized track 010 can be closed at the intermediate position, thereby improving the user experience.

There are also electric curtains, which are not length-adjustable, and are not well-fitted after a long period of use. The trolley can also be adjusted to the initial position by the method described above so that the trolley can be closed in the intermediate position.

Still further, the transmission 300 further comprises a locking assembly 350, the locking assembly 350 cooperating with the first transmission 310 for locking the first transmission 310 in a position for driving connection with the second transmission 320. In this way, after the first transmission mechanism 310 and the second transmission mechanism 320 are disconnected and restored to be connected, the locking assembly 350 locks the first transmission mechanism 310 at the position where the first transmission mechanism 310 is connected with the second transmission mechanism 320, so as to ensure the stable cooperation between the first transmission mechanism 310 and the second transmission mechanism 320 and improve the user experience.

Referring to fig. 3 and 9, in order to better connect or disconnect the first transmission mechanism 310 and the second transmission mechanism 320 in a transmission manner; the first transmission mechanism 310 comprises a first assembly part 331 and a first transmission component 311 arranged on the first assembly part 331, and the first transmission component 311 is in transmission connection with the first pulley 110; the first assembly 331 is configured to be movable relative to the second transmission mechanism 320 to drivingly connect or disconnect the first transmission assembly 311 to the second transmission mechanism 320. Thus, the first assembly 331 moves relative to the second transmission mechanism 320, so that the first transmission assembly 311 and the second transmission mechanism 320 can be connected or separated in a transmission manner, the operation is simple, and the transmission connection between the first transmission assembly 311 and the first pulley 110 is not easily interfered or damaged.

Further, the second transmission mechanism 320 includes a second assembly 332 and a second transmission component 321 disposed on the second assembly 332, and the second transmission component 321 is in transmission connection with the second sled 210; the second assembly part 332 is arranged on the second rail 200, and the first assembly part 331 is movably connected with the second assembly part 332; wherein, under the condition that the first assembly part 331 moves relative to the second assembly part 332, the first transmission component 311 can be in transmission connection with or separated from the second transmission component 321. Therefore, the first assembly part 331 moves relative to the second assembly part 332, so that the first transmission component 311 and the second transmission component 321 are connected or separated in a transmission manner, the operation is simple, and the interference and the damage on the transmission connection between the first transmission component 311 and the first pulley 110 and the transmission connection between the second transmission component 321 and the second pulley 210 are not easy to occur.

In other embodiments, the second fitting 332 is disposed at a lengthwise extension of the second rail 200, such as: independently set up in installation positions such as ceiling.

In this embodiment, the first transmission mechanism 310 can move along the length extension direction of the second track 200 relative to the second transmission mechanism 320; specifically, the first fitting 331 is movable relative to the second fitting 332 along a length extension direction of the second rail 200 to couple or decouple the first driving member 311 and the second driving member 321. Thus, when the first transmission unit 311 and the second transmission unit 321 need to be connected or disconnected (disconnected), the first assembly 331 only needs to be moved in the longitudinal direction of the second rail 200, which facilitates the relative movement between the first assembly 331 and the second assembly 332, and thus the operation is simple.

It should be noted that, in the present embodiment, the first assembly member 331 and the second assembly member 332 may be a gear box, a mounting plate, a mounting column, and the like, and are not limited in particular.

The first assembly part 331 is provided with a sliding groove 341, the second assembly part 332 is provided with a guiding part 342, and the guiding part 342 and the sliding groove 341 are slidably inserted and connected for guiding the first assembly part 331 to move relative to the second assembly part 332 and enabling the first transmission component 311 and the second transmission component 321 to be in transmission connection or separation. In this way, the relative movement of the first assembly 331 and the second assembly 332 can be more stable, and the first transmission component 311 and the second transmission component 321 can be reliably connected or disconnected in a transmission manner.

Of course, in other embodiments, the first fitting part 331 is provided with the guide member 342, the second fitting part 332 is provided with the sliding groove 341, and the guide member 342 and the sliding groove 341 are slidably inserted.

It should be noted that the sliding groove 341 and the guiding element 342 extend along the length extension direction of the second rail 200, so that the first assembly part 331 can be guided to move relative to the second assembly part 332 along the length extension direction of the second rail 200, so as to drivingly connect or disconnect the first transmission component 311 and the second transmission component 321. Specifically, when the first assembly 331 moves in the forward direction along the length extension direction of the second rail 200, the first transmission assembly 311 is separated from the second transmission assembly 321; when the first assembly 331 moves reversely along the length extension direction of the second rail 200, the first transmission assembly 311 is in transmission connection with the second transmission assembly 321.

It should be understood that in other embodiments, the chute 341 and the guide 342 may also extend in a direction perpendicular to the length extension of the second rail 200, for example: the sliding groove 341 and the guide piece 342 extend in the vertical direction, and the first assembly part 331 can be close to the second assembly part 332 in the vertical direction so as to drive and connect the first transmission component 311 with the second transmission component 321; alternatively, the first fitting 331 can be spaced apart from the second fitting 332 in a vertical direction to separate the first driving member 311 from the second driving member 321.

Of course, in other embodiments, the extending direction of the sliding groove 341 and the guiding element 342 may also be a direction which is perpendicular to the length extending direction of the second track 200 and has an angle of 1 °, 3 ° or the like.

It should be further noted that the number of the sliding grooves 341 and the guiding members 342 can be selected according to the requirement, the first assembly member 331 of the present embodiment is provided with two sliding grooves 341, the second assembly member 332 is provided with two guiding members 342, and the two sliding grooves 341 and the two guiding members 342 are correspondingly inserted and matched one by one. In other embodiments, the number of the sliding grooves 341 and the guiding members 342 may also be one, three, etc., and is not limited herein.

The transmission device 300 further includes a motor (not shown) in transmission connection with the second transmission mechanism 320, so that when the first transmission mechanism 310 and the second transmission mechanism 320 are in transmission connection, the motor is used to simultaneously control the first transmission mechanism 310 and the second transmission mechanism 320, and thus simultaneously control the opening or closing of the first curtain and the second curtain. Of course, in other embodiments, the motor may also be in driving connection with the first transmission mechanism 310.

Referring to fig. 3, 4 and 5, the first transmission mechanism 310 includes a first transmission component 311, a first transmission belt 314, a fifth gear 315 and a sixth gear 316, the first transmission component 311 includes a first gear 312 and a second gear 313, the sixth gear 316 and the fifth gear 315 are respectively disposed at two ends of the first rail 100 in the length direction, the first gear 312 and the second gear 313 are coaxially and fixedly connected and disposed on the first assembly 331, the first gear 312 is in transmission connection with the first transmission belt 314, and specifically, the first transmission belt 314 is simultaneously tensioned on the first gear 312, the fifth gear 315 and the sixth gear 316; the first driving belt 314 is in driving connection with the first pulley 110; the second transmission mechanism 320 comprises a second transmission component 321, a second transmission belt 324 and a seventh gear 325, the second transmission component 321 comprises a third gear 322 and a fourth gear 323, the third gear 322 and the seventh gear 325 are respectively arranged at two ends of the second rail 200 in the length direction, the third gear 322 and the fourth gear 323 are coaxially and fixedly connected and arranged on the second assembly part 332, the third gear 322 is in transmission connection with the second transmission belt 324, and specifically, the second transmission belt 324 is simultaneously tensioned on the third gear 322 and the seventh gear 325; the second driving belt 324 is in driving connection with the second pulley 210; the output shaft of the motor is in transmission connection with a seventh gear 325; the second gear 313 can move relative to the fourth gear 323 to engage with or disengage from the fourth gear 323, and specifically, when the first assembly 331 moves relative to the second assembly 332, the first gear 312 and the second gear 313 are driven to move synchronously, so that the second gear 313 engages with or disengages from the fourth gear 323 disposed on the second assembly 332.

In other embodiments, the output shaft of the motor may also be in transmission connection with other gears such as the fifth gear 315 and the sixth gear 316, which are not limited herein.

Under the condition that the second gear 313 is meshed with the fourth gear 323, the output shaft of the motor drives the seventh gear 325 to rotate, the second transmission belt 324 is driven to move, meanwhile, the fourth gear 323 drives the second gear 313 to rotate, and then the first transmission belt 314 is driven to move, so that the first pulley 110 and the second pulley 210 can be synchronously driven to move, and the first curtain and the second curtain can be synchronously controlled to be opened or closed. With the second gear 313 and the fourth gear 323 separated, the user can manually drive the first sled 110 and the second sled 210 to move independently, thereby enabling the first sled 110 and the second sled 210 to move to the corresponding initial positions.

The initial position of the first pulley 110 is a position at the end of the first rail 100, and the first curtain provided on the first pulley 110 is in a fully opened state; the initial position of the second tackle 210 is the end of the second track 200, and the position of the second curtain arranged on the second tackle 210 is in the 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.

It should be noted that, after the length of the electric track 010 is adjusted, the second gear 313 is separated from the fourth gear 323, the first transmission mechanism 310 and the second transmission mechanism 320 do not interfere with each other in operation, and after the user manually moves the first pulley 110 and the second pulley 210 to the corresponding initial positions, the second gear 313 is engaged with the fourth gear 323, that is, the motor can be used to drive the first transmission mechanism 310 and the second transmission mechanism 320 to drive the first curtain and the second curtain to move simultaneously, so as to open or close the curtain, and when the curtain is closed, the first curtain and the second curtain can be closed at the middle position in the length direction of the electric track 010, so as to improve the user experience.

In order to enable the first and second belts 314, 324 to securely mate with the first and third gears 312, 322, respectively, the first and second belts 314, 324 are toothed belts. Of course, in other embodiments, the first belt 314 and the second belt 324 may be replaced by a drive chain.

Referring to fig. 3, in the present embodiment, the locking component 350 is disposed on the second assembly part 332, and the locking component 350 is used for locking the first assembly part 331 at a position where the first transmission component 311 is in transmission connection with the second transmission component 321, or for releasing the position locking of the first assembly part 331, so that the first assembly part 331 can move relative to the second assembly part 332. Thus, when the first transmission component 311 and the second transmission component 321 need to be in transmission connection, the position of the first assembly part 331 is locked by the locking component 350 to ensure that the first transmission component 311 and the second transmission component 321 are reliably in transmission connection, and when the first transmission component 311 and the second transmission component 321 need to be separated, the position locking of the first assembly part 331 is released by the locking component 350 to avoid the locking component 350 from interfering with the separation of the first transmission component 311 and the second transmission component 321, so that the first tackle 110 and the second tackle 210 can move independently without interfering with each other.

Further, the locking assembly 350 is also used to disengage the first transmission mechanism 310 from the second transmission mechanism 320 from the transmission connection; specifically, the locking assembly 350 of the present embodiment can be in driving engagement with the first assembly member 331; while the locking component 350 releases the position lock of the first assembly 331, the locking component 350 can move the first assembly 331 relative to the second assembly 332, so as to separate the first transmission component 311 and the second transmission component 321. Therefore, when the locking component 350 releases the position locking of the first assembly part 331, the first transmission component 311 and the second transmission component 321 are conveniently and rapidly separated, and the operation efficiency is improved.

Referring to fig. 3 and 6, the locking assembly 350 includes a movable member 351 and a stop member 354 disposed on the movable member 351, the movable member 351 is rotatably connected to the second assembly member 332, and the movable member 351 has a locking position and an unlocking position; when the movable element 351 is located at the locking position, the stop piece 354 abuts against the first assembly part 331, and the movable element 351 can lock the first assembly part 331 at a position where the first transmission component 311 and the second transmission component 321 are in transmission connection; with the movable member 351 located at the unlocking position, the first transmission member 311 is separated from the second transmission member 321. Therefore, the first assembly part 331 can be unlocked and locked only by rotating the movable part 351, and the operation is convenient and fast.

When the movable member 351 moves to the unlocking position, the stop member 354 can drive the first assembly member 331 to move relative to the second assembly member 332, so that the first transmission component 311 is separated from the second transmission component 321; when the movable member 351 moves to the locking position, the stopping member 354 can drive the first assembly member 331 to move relative to the second assembly member 332, so that the first transmission component 311 is in transmission connection with the second transmission component 321. Thus, the locking assembly 350 can quickly, efficiently and stably realize the transmission connection or disconnection between the first transmission assembly 311 and the second transmission assembly 321, and the operation is easy.

The structure of the stopping member 354 can be selected as required, the stopping member 354 of this embodiment includes a first stopping portion 355 and a second stopping portion 356, the movable member 351 includes a movable member body 352 and a rotating shaft 353 disposed on the movable member body 352, the rotating shaft 353 is rotatably connected to the second assembly member 332, the first stopping portion 355 is disposed on the rotating shaft 353, and the length extending direction of the first stopping portion 355 and the axial line extending direction of the rotating shaft 353 are distributed at an included angle; the second abutting portion 356 is disposed on a side of the first abutting portion 355 away from the rotation shaft 353, and a length extending direction of the second abutting portion 356 is parallel to an axial extending direction of the rotation shaft 353; when the movable member 351 is located at the locking position, the first abutting portion 355 and the second abutting portion 356 are both abutted to the first assembly member 331, the first abutting portion 355 is used for blocking the first transmission component 311 from being separated from the second transmission component 321, and the second abutting portion 356 is used for blocking the first transmission component 311 from moving beyond the position where the first transmission component 311 is in transmission connection with the second transmission component 321; specifically, when the movable member 351 is located at the locking position, the second stopping portion 356 is used to stop the first transmission component 311 from moving beyond the position where the second gear 313 is meshed with the fourth gear 323. Through the arrangement of the first stopping part 355 and the second stopping part 356, not only the first assembly part 331 can be locked to ensure that the first transmission component 311 is reliably in transmission connection with the second transmission component 321, but also the first transmission component 311 and the second transmission component 321 are prevented from being excessively extruded after transmission connection, namely, the second gear 313 and the fourth gear 323 are prevented from being excessively extruded after being meshed, and the problem that the second gear 313 and the fourth gear 323 are easily damaged when being meshed is solved.

Further, when the movable element 351 moves to the unlocking position, the second stopping portion 356 can drive the first assembly 331 to move relative to the second assembly 332, so that the first transmission component 311 is separated from the second transmission component 321; when the movable element 351 moves to the locking position, the first stopping portion 355 can drive the first assembly 331 to move relative to the second assembly 332, so that the first transmission component 311 is in transmission connection with the second transmission component 321. Therefore, when the movable element 351 rotates relative to the second assembly 332, the first assembly 331 is driven to move relative to the second assembly 332 by the second abutting portion 356 or the first abutting portion 355, so that the first transmission component 311 and the second transmission component 321 are in transmission connection or disconnection, and the operation is simple and the efficiency is improved.

In other embodiments, when the movable member 351 is located at the unlocked position, the first abutting portion 355 and the second abutting portion 356 are both separated from the first assembly 331, so that the first assembly 331 can move relative to the second assembly 332, and further the first transmission assembly 311 can be separated from or in transmission connection with the second transmission assembly 321, that is, when the movable member 351 is located at the unlocked position and the first abutting portion 355 and the second abutting portion 356 are both separated from the first assembly 331, a worker can manually move the first assembly 331 to separate the first transmission assembly 311 from the second transmission assembly 321.

Note that the structure and shape of the moving element body 352 may be set as needed, and the moving element body 352 of the present embodiment is a plate-shaped toggle plate to ensure sufficient structural strength of the moving element 351.

Further, with reference to fig. 6 to 9, the first stopping portion 355 may be a stopping plate connected to the end of the rotation shaft 353, and the stopping plate is connected to the rotation shaft 353 perpendicularly; the second stopping portion 356 may be a stopping post connected to the stopping plate, and an axis of the stopping post is parallel to an axis of the rotating shaft 353; thus, when the movable element 351 is located at the locking position, one end of the stop plate, which is far away from the rotating shaft 353, abuts against the first assembly part 331, and the outer peripheral wall of the stop column abuts against the first assembly part 331, so that the first assembly part 331 can be reliably locked at the position where the first transmission component 311 and the second transmission component 321 are in transmission connection; when the movable member 351 rotates to the unlocking position, one end of the stop-and-go plate is separated from the first assembly part 331, the stop-and-go post keeps being abutted against the first assembly part 331, and because the axis of the stop-and-go post is distributed in parallel with the axis of the rotating shaft 353, the stop-and-go post rotates around the rotating shaft 353 to drive the first assembly part 331 to move forward along the length extending direction of the second track 200, so that the stop-and-go post is utilized to drive the first assembly part 331 to move relative to the second assembly part 332, and further the first transmission component 311 synchronously moves until the first transmission component 311 is disconnected from the second transmission component 321 in transmission connection; when the movable member 351 is rotated at the locking position, one end of the stop plate away from the rotating shaft 353 is rotated to abut against the first assembly part 331, and one end of the stop plate away from the rotating shaft 353 is rotated around the rotating shaft 353, so that one end of the stop plate away from the rotating shaft 353 abuts against the first assembly part 331, the first assembly part 331 is driven to move reversely along the length extending direction of the second rail 200 relative to the second assembly part 332, and the first transmission component 311 is driven to synchronously move until the first transmission component 311 is in transmission connection with the second transmission component 321.

Further, the first fitting part 331 includes a first wall 361 and a second wall 362 which are opposite and spaced apart from each other, a receiving space is provided between the first wall 361 and the second wall 362, and the abutting column and a part of the abutting plate are located in the receiving space; when the movable member is located at the locking position, the stop column abuts against the first wall 361, and one end of the stop plate, which is far away from the rotating shaft 353, abuts against the second wall 362; when the movable member moves to the unlocking position, one end of the stop plate, which is far away from the rotating shaft 353, is separated from the second wall 362, and the stop column abuts against the first wall 361, so that the first assembly part 331 is pushed to move relative to the second assembly part 332; when the movable member moves to the locking position, one end of the stop plate away from the rotation shaft 353 abuts against the second wall 362, and pushes the first assembly member 331 to move relative to the second assembly member.

In other embodiments, when the movable member 351 is rotated to the unlocking position, the one end of the stop plate and the stop column rotate around the rotation shaft 353 synchronously, so that the one end of the stop plate and the peripheral wall of the stop column are both separated from the first assembly part 331, the first assembly part 331 can move relative to the second assembly part 332 under the action of an external force, and the first transmission component 311 is in transmission connection with or separated from the second transmission component 321.

It should be noted that, in this embodiment, when the movable piece 351 rotates until the movable piece main body 352 extends in the vertical direction, the movable piece 351 is located at the locking position; when the movable member 351 rotates to the position where the movable member body 352 extends in the horizontal direction, the movable member 351 is located at the unlocking position. Of course, in other embodiments, when moveable member 351 rotates until moveable member body 352 extends horizontally, moveable member 351 is in the locked position; when the movable piece 351 rotates to the position that the movable piece body 352 extends in the vertical direction, the movable piece 351 is located at the unlocking position; and is not particularly limited herein.

The manner of the stop member 354 disposed on the moving member 351 can be selected as required, and the stop member 354 and the moving member 351 of the present embodiment are integrally formed, that is, the moving member body 352, the rotating shaft 353, the first stop portion 355 and the second stop portion 356 are integrally formed. Of course, in other embodiments, the stopping element 354 and the movable element 351 may also be welded or adhered, and the like, and are not limited in this respect.

The number of the stop members 354 disposed on the movable member 351 can be selected as required, and the locking assembly 350 of the embodiment includes two stop members 354, and the two stop members 354 are disposed at two axial ends of the rotating shaft 353 respectively. Thus, when the movable element 351 is located at the lock position, the first attachment 331 can be more stably and reliably locked at the position where the first transmission element 311 and the second transmission element 321 are drivingly connected by the abutment of the two abutting pieces 354 with the first attachment 331.

In order to facilitate assembling the locking assembly 350, the second assembly member 332 further defines two opening slots 334, and the rotation shaft 353 of the movable member 351 is inserted into the opening slots 334. Further, the two opening grooves 334 are disposed on both sides of the avoiding opening 333 along the axial direction of the rotation shaft 353, so that the movable member 351 can be ensured to rotate smoothly, and the second assembly 332 can be ensured not to interfere with the rotation of the movable member 351.

It should be understood that in other embodiments, the locking component 350 includes a fastener such as a screw or a bolt, and when the first assembly 331 moves relative to the second assembly 332 to drivingly connect the first transmission component 311 with the second transmission component 321, the first assembly 331 and the second assembly 332 can be connected together by the fastener such as the screw or the bolt, i.e. the relative positions of the first assembly 331 and the second assembly 332 can be locked, so that the first transmission component 311 and the second transmission component 321 are reliably drivingly connected; when it is required to enable the first assembly part 331 to move relative to the second assembly part 332, the fasteners such as bolts or screws may be removed, and the first assembly part 331 and the second assembly part 332 are no longer connected by the fasteners, i.e., the first assembly part 331 is moved relative to the second assembly part 332, so that the first transmission component 311 is separated from or in transmission connection with the second transmission component 321.
