Moreover, since the locking support 16 is fixed on the track body 11, the sliding of the trolley 14 in the track body 11 is blocked, the trolley 14 on the track body 11 is divided into left and right sides, the window curtain is opened and closed on both sides, and the trolley 14 in the middle is limited. The disassembly process is opposite, and only the blocking part 1611 is rotated by 90 degrees to be parallel to the opening slot 113 of the track body 11, so that the blocking part 1611 can be separated from the track body 11, without any additional tools.

[0044] In the embodiment, the supporting part 162 is in a flat ⊥ shape, and the ⊥ shape structure just forms two supporting parts 1621, so that the transmission rod 13 can fall into one of the two supporting parts 1621 no matter which direction the blocking part 1611 is rotated by 90 degrees. A friction sleeve 163 is sleeved on the blocking part 1611, and a friction tooth 1631 for increasing friction is engraved on the position of the friction sleeve 163 in contact with the bottom edge of the track body 11, so as to prevent the locking support 16 from sliding on the track body 11. Meanwhile, the friction sleeve 163 also facilitates the rotation of the blocking part 1611. The friction sleeve 163 can be made of rubber material or plastic material.

[0045] In the embodiment, the connecting part 1612 is in a column shape, and the connecting part 1612 can be rotated in the opening slot 113 of the track body 11. The blocking part 1611 and the connecting part 1612 are integrally arranged, a connecting hole 1622 matched with one end of the connecting part 1612 is arranged on the supporting part 162, a threaded hole (such as a second threaded hole 1623 in Figure 4 ) is further arranged at the bottom of the connecting hole 1622, and a threaded hole (such as a first threaded hole 1613 in Figure 4 ) is arranged in the connecting part 1612. After the connecting part 1612 is inserted into the connecting hole 1622, a long screw 164 is sequentially threaded through the two threaded holes (the first threaded hole 1613 and the second threaded hole 1623) and connected with the connecting part 1612, thereby improving the firmness of the connection.

[0046] In order to facilitate installation and disassembly, in the embodiment, a long screw 164 is arranged on the connecting part 1612, and the long screw 164 is connected with the connecting hole 1622 through the threaded hole (such as the first threaded hole 1613 in Figure 7The two ends of the track body 11 are also respectively provided with the locking support 16 near the outermost pulley 14, which is used to block the sliding of the outermost pulley 14, and the locking support 16 locks the two outermost pulleys 14 at the two ends of the track body 11 to prevent light leakage on both sides of the curtain. The locking support 16 is installed near the outermost pulley 14 and close to the wall on both sides of the curtain, so that the two outermost pulleys 14 are fixed and cannot move along the track body 11. The locking support 16 can also be installed at any position of the track body 11 according to the actual application scene of the user.

[0047] The application also provides an electric curtain device with the support and fixing structure, as shown in Figure 1 、 Figure 17 , which comprises a track assembly 1 and a driving assembly 2. Figure 7 The track assembly 1 comprises a track body 11, a transmission belt 12, a transmission rod 13, a pulley 14, a linkage piece 18, a hook 15 and a locking support 16 arranged in the track body 11.

[0048] As shown in Figure 2 、 Figure 3 , the track body 11 is a hollow structure 131, and in the embodiment, a rubber strip 19 is arranged in the track body 11. The cross section of the track body 11 is generally rectangular, and four accommodation grooves are arranged at the four corners of the rectangle. The two upper accommodation grooves are first accommodation grooves 111, and the two lower accommodation grooves are second accommodation grooves 112. Figure 7 、 Figure 23 The track body 11 is provided with a driving pulley 121 and a driven pulley at the positions near the top surface at the two ends, respectively. The transmission belt 12 is wound around the driving pulley 121 and the driven pulley and also around the two first accommodation grooves 111 on the track body 11. The transmission belt 12 runs in the horizontal direction under the driving of the driving pulley 121. The first accommodation grooves 111 are provided with avoiding notches 1111 for avoiding the connection of the connecting piece 17 connected with the transmission belt 12.

[0049] The second accommodating groove 112 of the track body 11 is provided with an opening 1121, the rubber strip 19 comprises an embedded part 191 and a fitting part 192, the embedded part 191 is matched with the second accommodating groove 112 and the opening 1121, the embedded part 191 is embedded in the second accommodating groove 112, the two rubber strips 19 are fixed on the two second accommodating grooves 112 through the embedded part 191, and the fitting part 192 of the rubber strip 19 is in contact with the inner side and the inner bottom of the track body 11. The transmission rod 13 and the trolley 14 collide with the track body 11 and the parts connected with the track body 11 to generate noise during operation, and the rubber strip 19 covers the inner side of the track body 11, so that the noise generated during the operation of the transmission rod 13 and the like can be reduced.

[0050] As Figure 2 , Figure 3 , the two inner sides of the track body 11 are symmetrically provided with a rib plate 114, the upper edge of the fitting part 192 of the rubber strip 19 abuts on the lower surface of the rib plate 114, and the rubber strip 19 is limited. At the same time, the two sides of the trolley 14 are provided with pulleys 142, and the two pulleys 142 run on the upper surfaces of the rib plates 114 on the two sides.

[0051] The top surface of the track body 11 extends the convex edges 115 on the two sides along the length of the track, the convex edges 115 are along the length direction of the track body 11, the convex edges 115 are used for clamping with the top mounting plate 3 of the curtain track, and the top mounting plate 3 is provided with a clamping groove 31 matched with the convex edges 115. When installing, the clamping groove 31 of the top mounting plate 3 is only needed to be slid along the convex edges 115 of the track body 11, so that the top mounting plate 3 can be clamped on the track body 11, and the installation is convenient without additional installation tools such as screws.

[0052] The transmission rod 13 is rotatably installed below the transmission belt 12 and parallel to the track body 11, and located in the middle of the cavity of the track body 11. Figure 3 , Figure 4 A plurality of trolleys 14 are sleeved on the transmission rod 13 and can move along the transmission rod 13, the external shape of the trolley 14 is matched with the internal cavity of the track body 11, so that the trolley 14 can move in the cavity of the track body 11. The transmission structure 144 is arranged in the trolley 14, the hook 15 is connected to the transmission structure 144, the transmission structure 144 is connected with the transmission rod 13 at the same time, and the transmission structure 144 converts the rotation of the transmission rod 13 in the vertical direction into the rotation of the hook 15 in the horizontal direction.

[0053] The transmission structure 144 can adopt existing structures or forms capable of transmitting power between two intersecting shafts, such as a worm gear and turbine structure, or a two-bevel gear structure. As one such form, in this embodiment, for example... Figure 5 , Figure 6 The transmission structure 144 is mainly a turbine and worm structure, including a meshing turbine 1442 and a worm 1441. The worm 1441 is a hollow shaft structure with conventional helical teeth that mesh with the turbine 1442 on its outer surface. The hollow shaft of the worm 1441 has a shape that matches the outer cross-section of the transmission rod 13, or a bushing 1443 is fitted inside the hollow shaft of the worm 1441. The bushing 1443 has a shape that matches the outer cross-section of the transmission rod 13. The worm 1441 is fitted onto the transmission rod 13 through the cooperation of the hollow shaft or bushing 1443, and can move along the direction of the transmission rod 13. The transmission rod 13 drives the worm 1441 to rotate through the cooperation of the hollow shaft or bushing 1443. As one example, as shown in the figure, the transmission rod 13 is a hexagonal rod, and a bushing 1443 is fitted onto the hollow shaft of the worm gear 1441. The inner surface of the bushing 1443 is also hexagonal. The transmission rod 13 drives the worm gear 1441 to rotate through the bushing 1443. The hook 15 is connected to the turbine 1442 and is coaxially arranged with the turbine 1442. When the transmission rod 13 rotates in the vertical direction, it drives the worm gear 1441 to rotate in the vertical direction. The worm gear 1441 drives the turbine 1442 and the hook 15 to rotate in the horizontal direction.

[0054] In this embodiment, in addition to the transmission structure 144 and pulleys 142, the trolley 14 also includes a trolley body 141 and a linkage plate receiving plate 143. The trolley body 141 is provided with corresponding space and structure for installing the transmission structure 144. The pulleys 142 are installed on both sides of the trolley body 141 and travel along the ribs 114 on the inner side of the track body 11. The linkage plates 18 are installed on the linkage plate receiving plate 143, and the linkage plates 18 are connected front to back. The first trolley 140 is connected to the transmission belt 12 through a connector 17. The connector 17 connects the first trolley 140 and the transmission belt 12, with one end connected to the transmission belt 12 and the other end connected to the first trolley 140. In this embodiment, the connector 17 includes a belt clamp 171, a connecting plate 172, and a connecting post 173. The belt clamp 171 is clamped on one side of the transmission belt 12. The belt clamp 171 is connected to the upper surface of the connecting plate 172. One end of the connecting post 173 is connected to the lower surface of the connecting plate 172, and the other end of the connecting post 173 is connected to the first trolley 140.

[0055] The bottom of the track body 11 is provided with an opening slot 113 that allows a hook 15 to pass through. One end of the hook 15 is connected to the transmission structure 144, and the other end extends out of the opening slot 113. The hook 15 is used to hang the curtain.Figures 7 to 9 The locking support 16 is installed in the middle of the slide body. The locking support 16 mainly serves to support and lock the partition. The locking support 16 blocks the passage of the trolleys 14. Several trolleys 14 are separated on the left and right sides of the locking support 16, thereby dividing the entire curtain into left and right sides. At the same time, the transmission rod 13 is supported on the locking support 16, which provides intermediate support for the transmission rod 13. The two trolleys 14 located on both sides of the locking support 16 are the first trolleys 140, that is, there is one first trolley 14 on each of the left and right sides. 0. The two first trolleys 140 are connected to two different sides of the transmission belt 12 via the connecting piece 17. Thus, when the transmission belt 12 rotates, the two sides move in different directions, causing the two first trolleys 140 to move in opposite directions, thereby achieving simultaneous opening and closing of both sides of the curtain. The remaining trolleys 14 on both sides of the locking support 16 are sequentially connected to the first trolleys 140 on the same side via the linkage piece 18. The first trolleys 140 drive the remaining trolleys 14 and the hooks 15 connected to the trolleys 14 to move sequentially to achieve opening and closing.

[0056] As one implementation method, in this embodiment, such as Figure 2 , Figure 10 The transmission rod 13 has a hollow structure 131. Two transmission rods 13 are connected by a connecting strip 20. The cross-section of the connecting strip 20 is adapted to the cross-section of the hollow structure 131 of the transmission rod 13. The connecting strip 20 achieves the internal connection of the transmission rods 13 by inserting its two ends into the two transmission rods 13 respectively. The hollow structure 131 of the transmission rod 13 can achieve internal connection. The advantage of internal connection is that it does not affect the back and forth passage of the trolley 14, and can increase the width of the curtain. Another advantage of the hollow structure 131 is that it can increase the outer diameter of the transmission rod 13 while reducing the weight of the transmission rod 13, thereby increasing its rigidity and reducing the probability of it bending. The increase in outer diameter also makes it less likely to fall out of the opening slot 113.

[0057] The transmission rod 13 can be a hollow hexagonal rod, rectangular rod, or splined rod. The cross-section of its hollow structure 131 can be hexagonal, rectangular, floral, or circular. The connecting strip 20 is hexagonal, rectangular, floral, or circular, and its cross-section matches the cross-section of the hollow structure 131 of the transmission rod 13. Combining these two elements allows for various implementation methods, such as... Figure 2 , Figure 10 The hollow interior shown is also a hexagonal rod, such as... Figure 11 The hexagonal bar shown has a rectangular hollow interior, as... Figure 12 The spline bar shown has a hollow hexagonal interior, as... Figure 13 The spline bar shown has a rectangular hollow interior.
