Description

Technical Field

[0001] This utility model relates to the field of electric curtain accessories, and in particular to an easy-to-bend electric curtain track structure. Background Technology

[0002] Chinese patent document CN217338171U discloses a technical solution entitled "A Hand-Bendable Electric Curtain Rail". The technical solution includes the following technical features: curtain track, main transmission box, motor, curtain slider, trolley, auxiliary transmission box, transmission belt, slider support plate, protrusion, sliding groove, second horizontal partition, central vertical partition, transmission groove, protrusion block, inclined baffle, reinforcing rib, first horizontal partition, support horizontal plate and vertical partition, etc.

[0003] In this technical solution, although the curtain track can meet the sliding installation requirements of the trolley, the overall height of the curtain track is relatively large due to its structure (see the attached diagram in its instruction manual). Figure 2 and Figure 4 Furthermore, the lack of any radial reinforcement structure in the curtain track means it can only withstand weak radial forces. Therefore, such curtain tracks are prone to loosening, deformation, or damage under large radial forces (primarily because excessive radial force is directly transmitted to the locking components, leading to loosening), for example, when there is significant airflow through the window acting on the curtains or when someone accidentally pulls the curtains, the radial force on the curtain track can easily become excessive, resulting in loosening, deformation, or damage.

[0004] Therefore, it is essential to design an easy-to-bend motorized curtain track structure to solve the aforementioned technical problems. Utility Model Content

A limit plate is provided on the sliding block or the extension block, and an anti-fall protrusion is provided on the limit plate, with the anti-fall protrusion located directly below the hinge shaft.

[0014] Preferably, the track body is a plastic profile track; the track body includes a front strip, a rear strip, a front support strip, a rear support strip, a lower strip, an upper strip, a middle strip, a front stop strip, and a rear stop strip. The front and rear strips are arranged side-by-side and parallel to each other.

[0024] like Figure 1 As shown, the present invention provides a flexible electric curtain track structure, which includes a flexible track body 1. To achieve the purpose of the invention, the upper sides of the front and rear walls of the track body 1 are respectively provided with anti-sway strips 11 protruding forward and backward.

[0025] In this electric curtain track structure, anti-sway strips 11 are formed by protruding the upper sides of the front and rear walls of the track body 1 forward and backward, respectively. This not only enhances the structural strength of the track body 1 with the anti-sway strips 11, but also provides comprehensive and effective anti-swaying at the front and rear of the track body 1, limiting the amplitude of its back-and-forth swaying. Furthermore, when the track body 1 is subjected to radial forces, the anti-sway strips 11 effectively distribute the radial force, thus significantly enhancing its resistance to radial forces. Under large radial forces, it is less prone to loosening, deformation, or damage, exhibiting high reliability and applicability.

[0026] In actual installation, the track body 1 is mounted on the ceiling, and the two anti-sway strips 11 can be in full or mostly in contact with the ceiling; or, when the track body 1 is subjected to radial force, the anti-sway strips 11 can be in contact with the ceiling. This effectively enhances the track body 1's resistance to radial force, thus preventing loosening, deformation, and damage under large radial forces. The anti-sway strips 11 not only contact the ceiling to prevent swaying but also serve as fixing points for securing the track body 1 to the ceiling. Such fixing points facilitate easy fixation and ensure stable installation.

[0027] like Figures 2 to 6 As shown, the track body 1 is equipped with a trolley 2 that can slide laterally. A clamping arm 21 is located on the top of the trolley 2, and the clamping arm 21 has a clamping groove 211 with a narrow opening and a wide inner surface. The clamping groove 211 can be used to clamp the drive belt 3, which not only facilitates clamping the drive belt 3 but also provides a very stable and reliable clamping effect, thereby helping to further improve the reliability and applicability of the electric curtain track structure.

[0028] like Figure 3 and Figure 7 As shown, the clamping arm 21 includes a support strip 212, a vertical clamping plate 213, and an inclined clamping plate 214. The vertical clamping plate 213 and the inclined clamping plate 214 are arranged side by side on the support strip 212, with the inclined clamping plate 214 gradually approaching the vertical clamping plate 213 from bottom to top. The clamping groove 211 is formed between the inclined clamping plate 214 and the vertical clamping plate 213. One, two, or three of the support strip 212, vertical clamping plate 213, and inclined clamping plate 214 are connected to the top of the trolley 2. This clamping arm 21 is very simple and reliable, which not only facilitates manufacturing but also provides a sufficient clamping effect, thereby helping to further improve the reliability and applicability of the electric curtain track structure.

[0029] like Figure 7 As shown, the groove wall of the clamping groove 211 is provided with a toothed surface 215. This not only enhances the friction between the clamping arm 21 and the transmission belt 3, but also achieves toothed engagement when the transmission belt 3 is a toothed belt. This makes the clamping groove 211 more stable and reliable in clamping the transmission belt 3, thereby helping to further improve the reliability of the electric curtain track structure.

[0030] like Figures 2 to 6 As shown, the trolley 2 includes a connecting strip 22 and a sliding block 23. The sliding block 23 is slidably mounted on the track body 1, and the connecting strip 22 is detachably mounted on the sliding block 23. The clamping arm 21 is located on the upper end of the sliding block 23. This detachable connection between the sliding block 23 and the connecting strip 22 not only reduces manufacturing difficulty but also allows for the creation of more diverse trolleys 2 by combining different sliding blocks 23 and connecting strips 22, thus better meeting various usage needs and further improving the applicability of this electric curtain track structure.

[0031] like Figure 5 As shown, the connecting strip 22 is provided with at least one first hanging hole 221, and the side corner of the connecting strip 22 is provided with a staggered arm 222, the staggered arm 222 being provided with at least one second hanging hole 223. This not only meets the hanging requirements of the curtains, but also facilitates the staggered arrangement of the curtain ends, thereby enabling the curtain ends to achieve a better shading effect.

[0032] like Figure 1 , Figure 2 and Figure 7As shown, the sliding block 23 is provided with at least one laterally extending T-shaped protrusion 231, and the bottom surface of the track body 1 is provided with a laterally extending T-shaped guide groove 12, in which the T-shaped protrusion 231 is slidably fitted. This can accurately and stably limit the sliding block 23 on the track body 1, thereby helping to improve the accuracy and stability of the lateral sliding of the sliding block 23, and further helping to improve the reliability of the electric curtain track structure.

[0033] like Figure 1 , Figure 2 and Figure 7 As shown, the front and rear sidewalls of the track body 1 are respectively provided with laterally extending T-shaped grooves 13. The clamping arm 21 is laterally slidably arranged in the T-shaped groove 13. The upper end of the sliding block 23 is placed outside the opening of the T-shaped groove 13. A connecting block 25 is arranged at the opening of the T-shaped groove 13, and the clamping arm 21 and the sliding block 23 are connected through the connecting block 25. The T-shaped groove 13 can be used to accommodate the transmission belt 3 and the clamping arm 21. This not only avoids the transmission belt 3 and the clamping arm 21 from being exposed, but also uses the T-shaped groove 13 to restrict the transmission belt 3, which helps to further improve the stability and reliability of the transmission.

[0034] like Figures 2 to 5 , Figure 8 As shown, an extension block 26, capable of horizontal swinging, is hinged to the side wall of the sliding block 23. A secondary clamping arm 27 is provided on the extension block 26, and a secondary slot 271 with a narrow opening and a wide inner groove is formed on the secondary clamping arm 27. The secondary slot 271 can be used to clamp the transmission belt 3, which not only facilitates clamping the transmission belt 3 but also provides a very stable and reliable clamping effect. By hingedly setting the extension block 26 and providing the secondary clamping arm 27 on the extension block 26, the connection amount with the transmission belt 3 is increased, and the curved track body 1 can be easily passed through.

[0035] like Figure 2 , Figure 7 and Figure 8 As shown, in the actual manufacturing process, the secondary clamping arm 27 adopts the same structure as the clamping arm 21, and the secondary clamping arm 27 is placed in the T-shaped groove 13, while the extension block 26 is placed outside the T-shaped groove 13, so as to meet the requirements of stable clamping.

[0036] like Figure 2 , Figure 7 and Figure 8As shown, the extension block 26 is provided with at least one laterally extending T-shaped protrusion 261, which is slidably embedded in the T-shaped guide groove 12. This can accurately and stably limit the extension block 26 on the track body 1, thereby helping to improve the accuracy and stability of the lateral sliding of the extension block 26, and further helping to improve the reliability of the electric curtain track structure.

[0037] like Figures 3 to 6 As shown, the flexible motorized curtain track structure also includes a hinge shaft 28. The sliding block 23 and the extension block 26 are hinged together by the hinge shaft 28, which is vertically inserted through them. A limit plate 29 is provided on the sliding block 23 or the extension block 26. The limit plate 29 is provided with an anti-fall protrusion 291, which is located directly below the hinge shaft 28. This not only stably hinges the sliding block 23 and the extension block 26 together via the hinge shaft 28, but also uses the anti-fall protrusion 291 to prevent the hinge shaft 28 from falling, thereby helping to further improve the stability and reliability of the assembly of the sliding block 23 and the extension block 26.

[0038] like Figures 3 to 6 As shown, the hinge shaft 28 is made of screws and is hinged to the sliding block 23 or the extension block 26, which helps to form a more stable and reliable hinge effect.

[0039] like Figures 3 to 6 As shown, the limiting plate 29 and the connecting strip 22 are respectively arranged on the front and rear surfaces of the sliding block 23. The first mounting hole 221 also passes through the sliding block 23 and the limiting plate 29. The expansion block 26 has at least one third mounting hole 262. At least one locking screw 224 passes through the connecting strip 22, and the threaded end of the locking screw 224 passes through the connecting strip 22 and the sliding block 23 in sequence before being screwed onto the limiting plate 29. The lower end of the limiting plate 29 is bent towards the bottom surface of the sliding block 23 to form a fall-prevention protrusion 291, and the fall-prevention protrusion 291 also extends to the bottom surface of the connecting strip 22. This allows the limiting plate 29 and the connecting strip 22 to be installed on the sliding block 23 conveniently, stably, and reliably, thereby helping to further improve the convenience and stability of assembly.

[0040] like Figure 1As shown, the track body 1 is a plastic profile track; the track body 1 includes a front strip 14, a rear strip 15, a front support strip 16, a rear support strip 17, a lower strip 18, an upper strip 19, a middle strip 10, a front stop strip 20, and a rear stop strip 30. The front strip 14 and the rear strip 15 are arranged side by side and parallel to each other. The front support strip 16 is located on the lower rear side of the front strip 14, and the rear support strip 17 is located on the lower front side of the rear strip 15. The lower strip 18 is horizontally arranged between the front strip 14 and the rear strip 15, and its front and rear ends are connected to the front strip 14 and the rear strip 15, respectively. The lower strip 18, the lower ends of the front strip 14 and the rear strip 15, the front support strip 16 and the rear support strip 17 together form a T-shaped guide groove 12. The slats 19 are horizontally arranged above the lower slats 18. The middle slats 10 are vertically arranged between the upper slats 19 and the lower slats 18, with the upper and lower ends of the middle slats 10 connected to the middle of the upper slats 19 and the middle of the lower slats 18, respectively. The front baffle 20 and the rear baffle 30 are respectively arranged on the front and rear sides of the bottom surface of the upper slats 19. The upper end of the front slats 14, the front end of the lower slats 18, the middle slats 10, the front end of the upper slats 19, and the front baffle 20 together form a T-shaped groove 13. The upper end of the rear slats 15, the rear end of the lower slats 18, the middle slats 10, the rear end of the upper slats 19, and the rear baffle 30 together form a T-shaped groove 13. Two anti-sway strips 11 are formed by the front and rear ends of the upper slats 19 protruding from the front baffle 20 and the rear baffle 30, respectively. Using plastic profile tracks not only facilitates manufacturing but also ensures high structural reliability. By adopting the above-described structure, the track body 1 achieves advantages such as being ultra-narrow, ultra-light, and ultra-small, allowing for easy bending and better meeting practical usage needs, thereby improving the applicability of the motorized curtain track structure.

[0041] The above embodiments are preferred embodiments of this utility model. All structures similar to this utility model and equivalent changes thereof should fall within the protection scope of this utility model.
