Description

Technical Field

[0001] This utility model belongs to the field of electric curtain technology, specifically relating to an electric Roman rod curtain track. Background Technology

[0002] Curtains are made of materials such as cloth, linen, gauze, aluminum sheets, wood sheets, and metal, and serve the functions of shading, heat insulation, and regulating indoor light. Fabric curtains are categorized by material, including cotton gauze, polyester fabric, cotton-polyester blends, cotton-linen blends, and non-woven fabrics. Different materials, textures, colors, and patterns combine to create curtains of various styles, complementing different interior design styles.

[0003] Existing motorized curtain tracks use a motor to open and close the curtains. In existing single-opening curtain tracks, a sliding trolley is installed inside the track, and one end of the curtain is hung on the trolley. The trolley's movement drives the curtain to open and close. However, because of the trolley, when it reaches the farthest end of the track, it comes into contact with the end cap. Due to installation considerations, the curtain hooks on the trolley are generally not placed at the very end of the trolley, but rather at a certain distance. This results in the curtain not completely covering the entire track, leading to insufficient light leakage and affecting the user experience.

[0004] Secondly, whether it is a single-opening or double-opening curtain track, it generally involves inserting the motor's rotating shaft into the track and engaging with the synchronous belt inside the track to drive the trolley to move back and forth. There is no transmission transfer structure in the middle, which means that it can only be used with motors with long rotating shafts, thus affecting its range of motor applications.

The bottom of the rod 1 near the first decorative head 2 is provided with a drive device 14 that is connected to the trolley 11 and drives the trolley 11 to move back and forth along the track. That is, after one end of the curtain is hung on the first ring buckle 13, the trolley 11 is driven by the drive device 14 to move back and forth along the track, thereby moving the curtain and realizing the purpose of opening and closing the curtain. In addition, with the auxiliary extension arm, when the trolley moves to the end near the second decorative head, the outer end of the auxiliary extension arm is located below the second decorative head, so that the hanging curtain can cover the area below the decorative head. That is, when the curtain is closed, it can cover the entire range of the rod and extend outward by a certain distance, which improves the coverage of the curtain and avoids the problem of light leakage gaps and incomplete shading at the end, thereby improving the user experience.

[0049] In another embodiment, such as Figures 3 to 6As shown, an end cap 15 can be detachably installed at the end of the rod 1 furthest from the drive device. A first decorative head 2 is detachably fitted onto the outside of one end of the rod by screws, and a second decorative head 3 is detachably fitted onto the outside of the end cap 15 by screws. The drive device 14 is connected to the trolley 11 via a transmission assembly. The transmission assembly includes a sleeve 17, a transmission gear 18, and a synchronous belt 20 that connects the sleeve 17 and the transmission gear 18. Specifically, the synchronous belt 20 is wound around the outside of the sleeve 17 and the transmission gear 18, with one end of the synchronous belt 20 meshing with the transmission gear 18. The upper end of the rod 1 is open... A receiving cavity 21 is provided along its length and located above the track 10. The receiving cavity 21 is vertically connected to the track 10.

The lower end of the transmission gear 18 is provided with a transmission rod 181 that extends downward out of the transmission box bracket 4 and is connected to the drive device 14. Here, by adding a transmission gear and a transmission box bracket that are connected to the drive device, and using the transmission rod that protrudes downward out of the transmission box bracket on the transmission gear to connect with the drive device, the drive device achieves an external structure. In this way, according to actual needs and the type of motor used, the corresponding transmission gear can be replaced to realize the transmission connection between the motor with or without a long rotating shaft and the internal transmission belt, thus improving the applicability of the motor used in this electric curtain track. If used with a motor without a long rotating shaft, a transmission gear with several slots 182 on the outer periphery of the lower end of the transmission rod 181 (such as...) Figure 11 As shown), the slot engages with the rotating end of the motor (as shown). Figure 12 (as shown); for example, when used with a motor with a long rotating shaft, a transmission gear with a square slot 183 in the middle of the lower end of the transmission rod 181 is used (as shown). Figure 13 As shown), the rotating shaft protruding outward at one end of the motor can be directly inserted into the square slot to achieve a snap-fit ​​connection (as shown). Figure 14 (As shown).

[0051] In another embodiment, such as Figures 1 to 5As shown, the bottom of the transmission box bracket 4 is provided with an auxiliary fixing rail 41 located between the drive device 14 and the first decorative head 2. Here, the drive device 14 is set between the track 10 and the auxiliary fixing rail 41 at the bottom of the rod. After a curtain spanning the track 10 and the auxiliary fixing rail 41 is hung on the track 10 and the auxiliary fixing rail 41, the drive device located between the two can be covered by the curtain. Under normal use, the drive device covered by the curtain cannot be seen by the naked eye, thereby improving the aesthetics during use.

[0052] In another embodiment, such as Figures 5 to 8 As shown, the upper end of the trolley 11 is provided with two clamping members 111 that are inserted into the receiving cavity 21 and clamped and fixed to the synchronous belt 20. The inner wall of the clamping member 111 is provided with a plurality of toothed parts 112 that engage with the toothed grooves on the synchronous belt 20. The upper end of the clamping member 111 is an opening for the synchronous belt 20 to be inserted into the clamping member 111 from top to bottom, which facilitates the assembly and disassembly of the clamping member 111 and the synchronous belt 20. The lower end of the trolley 11 is provided with at least one fixed arm 113 that extends out of the rod body 1 and is used to fix the auxiliary extension arm 12. The auxiliary extension arm 12 is fixed to the fixed arms 113 of the two trolleys 11 by screws.

[0053] In another embodiment, such as Figures 1 to 8 As shown, the auxiliary extension arm 12 is provided with a first ring buckle 13 at both ends and the middle. A second ring buckle 22 located below the rod body 1 is detachably provided on the auxiliary fixed rail 41. A third ring buckle 23 located below the rod body 1 is detachably provided at one end of the track 10 near the drive device 14. Several fourth ring buckles 24 are provided between the trolley 11 and the third ring buckle 23, which are slidably provided on the track 10 and located below the rod body 1. When in use, one end of the curtain is hung on the second ring buckle 22 and the third ring buckle 23 as the immovable end, and the other end of the curtain... The curtain is hung on the first ring 13 as a movable end. The middle part of the curtain is hung on the fourth ring 24, and several fourth rings 24 are connected by a first traction rope 25. One end of the first traction rope 25 can be detachably fixed to the trolley 11 or the auxiliary extension arm 12, and the other end can be detachably fixed to the third ring 23. Therefore, the first traction rope 25 can increase the force points when the curtain moves, and avoid the problem of uneven sliding and loud noise caused by the downward eccentric force when the trolley 11 and the fourth ring 24 slide due to the influence of the curtain's weight.

[0054] In another embodiment, such as Figures 1 to 8As shown, the first ring 13 is threaded onto the auxiliary extension arm 12, facilitating its assembly and disassembly; both the track 10 and the auxiliary fixed rail 41 are detachably provided with a fixed seat 42, and the second ring 22 and the third ring 23 are respectively fixed to the two fixed seats 42 by screws; the fourth ring 24 is slidably disposed on the track 10 through the sliding member 26, and the inner side of the upper end of the sliding member 26 that contacts the track 10 is a conical surface 261, which reduces the contact area and sliding friction between the two, reduces the noise generated by friction when the two slide, and achieves the purpose of noise reduction.

[0055] In another embodiment, such as Figures 1 to 2 As shown, each end of the rod body 1 can be detachably provided with a vertically extending rearward fixed rod 16, which is used to fix the electric curtain track to the wall.

[0056] In other embodiments, the driving device is a motor.

[0057] In other embodiments, the sleeve may be replaced with a gear that meshes with a timing belt.

[0058] Example 2

[0059] like Figures 9 to 22 As shown, this embodiment provides a double-opening electric Roman rod curtain track, including a circular rod body 1 and a first decorative head 2 and a second decorative head 3 detachably disposed at both ends of the rod body 1. The bottom of the rod body 1 has a track 10 extending along its length. A first trolley 5 and a second trolley 6 are slidably disposed within the track 10. At the bottom of the rod body 1 near the first decorative head 2, a drive device 14 is provided, which is connected to and drives the first trolley 5 and the second trolley 6 to move towards or away from each other. That is, after one end of each of the two curtains is hung on the first trolley 5 and the second trolley 6 respectively, the drive device 14 drives the first trolley 5 and the second trolley 6 to move towards each other, causing both curtains to move toward the middle of the rod body, thus closing the curtains. When the first trolley 5 and the second trolley 6 move away from each other, the two curtains move toward the two ends of the rod body respectively, thus opening the curtains.

[0060] In one embodiment, such as Figures 15 to 19As shown, an end cap 15 can be detachably provided at the end of the rod 1 away from the drive device 14. The first decorative head 2 is detachably fitted onto the outside of one end of the rod by screws, and the second decorative head 3 is detachably fitted onto the outside of the end cap 15 by screws. The drive device 14 is connected to the first trolley 5 and the second trolley 6 via a transmission assembly. The transmission assembly includes a sleeve 17, a transmission gear 18, and a synchronous belt 20 connecting the sleeve 17 and the transmission gear 18.

The upper end of the rod 1 has an opening. A receiving cavity 21 extends along its length and is located above the track 10. The receiving cavity 21 is vertically connected to the track 10. The synchronous belt 20 is located in the receiving cavity 21. The transmission gear 18 is rotatably located in the rod 1 at one end away from the second decorative head 3 and is coaxially arranged with the drive device 14. The lower end of the transmission gear 18 extends out of the rod 1 and is connected to the drive device 14. The circular sleeve 17 is rotatably located in the end cover 15. The first trolley 5 and the second trolley 6 are respectively fixed on both sides of the synchronous belt 20, so that the first trolley 5 and the second trolley 6 can be driven to move in opposite directions or in opposite directions by the circular synchronous belt 20.

[0061] In another embodiment, such as Figures 11 to 19 As shown, the bottom of the rod body 1, away from the end cap 15, is provided with a transmission box bracket 4 fixed by screws. The transmission gear 18 is rotatably mounted on the transmission box bracket 4, and the drive device 14 is fixed on the transmission box bracket 4. The lower end of the transmission gear 18 is provided with a transmission rod 181 that extends downward out of the transmission box bracket 4 and is connected to the drive device 14. Here, by adding a transmission gear and a transmission box bracket that are connected to the drive device, and using the transmission rod that protrudes downward out of the transmission box bracket on the transmission gear to connect with the drive device, the drive device achieves an external structure. In this way, according to actual needs and the type of motor used, the corresponding transmission gear can be replaced to realize the transmission connection between the motor with or without a long rotating shaft and the internal transmission belt, thus improving the applicability of the motor used in this electric curtain track. If used with a motor without a long rotating shaft, a transmission gear with several slots 182 on the outer periphery of the lower end of the transmission rod 181 (such as...) Figure 11 As shown), the slot engages with the rotating end of the motor (as shown). Figure 12 (as shown); for example, when used with a motor with a long rotating shaft, a transmission gear with a square slot 183 in the middle of the lower end of the transmission rod 181 is used (as shown). Figure 13 As shown), the rotating shaft protruding outward at one end of the motor can be directly inserted into the square slot to achieve a snap-fit ​​connection (as shown). Figure 14 (As shown).

[0062] In another embodiment, such as Figures 15 to 19As shown, the bottom of the transmission box bracket 4 is provided with an auxiliary fixing rail 41 located between the drive device 14 and the first decorative head 2. Here, the drive device 14 is placed between the track 10 and the auxiliary fixing rail 41 at the bottom of the rod. Thus, after a curtain spanning the track 10 and the auxiliary fixing rail 41 is hung on the track 10 and the auxiliary fixing rail 41, the drive device located between the two can be covered by the curtain. Under normal use, the drive device covered by the curtain is not visible to the naked eye, thereby improving the aesthetics during use.

[0063] In another embodiment, such as Figures 18 to 20 As shown, the upper ends of the first trolley 5 and the second trolley 6 are each provided with two clamping members 111 that are inserted into the receiving cavity 21 and clamped and fixed to the synchronous belt 20. The inner wall of the clamping member 111 is provided with a plurality of toothed parts 112 that engage with the toothed grooves on the synchronous belt 20. The upper end of the clamping member 111 is an opening for the synchronous belt 20 to be inserted into the clamping member 111 from top to bottom, which facilitates the assembly and disassembly of the clamping member 111 and the synchronous belt 20.

[0064] In another embodiment, such as Figures 13 to 17As shown, at least one first ring buckle 13 located below the rod 1 can be detachably installed on both the first trolley 5 and the second trolley 6. A second ring buckle 22 located below the rod 1 can be detachably installed on the auxiliary fixing rail 41. A third ring buckle 23 located below the rod 1 can be detachably installed at one end of the track 10 near the end cap 15. Several fourth ring buckles 24 are provided between the second trolley 6 and the third ring buckle 23, which are slidably installed on the track 10 and located below the rod 1. That is, when in use, both ends of one curtain can be hung on the third ring buckle 23 respectively. On the first ring 13 of the second trolley 6, one end of the curtain hanging on the third ring 23 is fixed, while the other end hanging on the first ring 13 is movable. The middle part of this curtain is hung on multiple fourth rings 24, and the multiple fourth rings 24 are connected by a first pull rope 25. One end of the first pull rope 25 is detachably fixed to the second trolley 6, and the other end is detachably fixed to the third ring 23. Therefore, the first pull rope 25 can increase the force points when the curtain moves, avoiding the influence of the curtain's weight. When the second trolley 6 and the fourth ring buckle 24 slide, the downward eccentric force causes uneven sliding and loud noise. A fifth ring buckle 27 located below the rod 1 is detachably installed at one end of the track 10 near the drive device 14. Several sixth ring buckles 28 are slidably mounted on the track 10 and located below the rod 1 between the first trolley 5 and the fifth ring buckle 27. In use, one end of another curtain can be hung on the fifth ring buckle 27 and the second ring buckle 22 as a fixed end, while the other end is hung on the first trolley 5. On the first ring 13, as a movable end, the middle part of this curtain is hung on multiple sixth rings 28, and the multiple sixth rings 28 are connected by a second traction rope 29. One end of the second traction rope 29 is detachably fixed to the first pulley 5, and the other end is detachably fixed to the fifth ring 27. Therefore, the second traction rope 29 can increase the force points when the curtain moves, and avoid the problem of uneven sliding and loud noise caused by the downward eccentric force when the first pulley 5 and the sixth rings 28 slide due to the influence of the curtain's weight.

[0065] In another embodiment, such as Figures 9 to 19 As shown, the first ring 13 is threadedly connected to the first trolley 5 or the second trolley 6; the third ring 23 and the fifth ring 27 are detachably mounted on the track 10 via the fixing seat 42, and the second ring 22 is detachably mounted on the auxiliary fixing rail 41 via the fixing seat 42; the fourth ring 24 and the sixth ring 28 are slidably mounted on the track 10 via the sliding member 26. The inner side of the upper end of the sliding member 26 that contacts the track 10 is a conical surface, which reduces the contact area and sliding friction between the two, and reduces the noise generated by friction when the two slide, thus achieving the purpose of noise reduction.

[0066] In another embodiment, such as Figures 15 to 16As shown, each end of the rod body 1 can be detachably provided with a vertically extending rearward fixed rod 16, which is used to fix the electric curtain track to the wall.

[0067] In other embodiments, the driving device is a motor.

[0068] In other embodiments, the sleeve may be replaced with a gear that meshes with a timing belt.
