Description

Technical Field

[0001] This application relates to the field of electric curtain technology, and in particular to cord winding modules and cord winding mechanisms. Background Technology

[0002] The winding module is a core component of electric lifting systems (such as electric curtains and projection screens). Its function is to drive the winding drum to rotate, thereby raising and lowering the lifting rope and achieving the lifting movement of the load. In applications such as double-curtain electric curtains, at least two independent winding modules are required to control the raising and lowering of the two curtain panels respectively.

[0003] In related technologies, a guide ramp is typically installed at the entry end of the lifting rope on the drum. This ramp ensures that the initial rope circumference is greater than the circumference of the subsequent sections of the drum. Since the rope at the rear of the drum is relatively slack, it doesn't become an obstacle due to gripping the drum tightly. This allows the newly wound rope to push the already wound rope towards the rear of the drum, thus achieving automatic rope arrangement. However, the pushing effect and rope arrangement stability of this method are highly dependent on the surface smoothness and coefficient of friction of the drum. During use, dust easily accumulates on the drum surface or wears down, altering its frictional characteristics. This can cause the rope arrangement process to fail or malfunction. Especially when the lifting rope is slack and winding continues, it can easily cause the lifting rope to accumulate on the drum, leading to knots and affecting the product's reliability and lifespan.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0024] In related technologies, a guide ramp is typically installed at the entry end of the lifting rope on the winding drum. The rope tension and contact with the ramp allow the lifting rope to slide automatically along the ramp during winding, thus achieving automatic positioning. However, this rope positioning method is highly dependent on the surface smoothness and friction coefficient of the winding drum. In actual use, dust, oil, or wear can easily accumulate on the drum surface, altering its frictional characteristics and causing positioning failures or malfunctions. This can lead to the lifting rope accumulating, loosening, or squeezing on the drum, ultimately resulting in unstable operation of the winding module, noise, or even knots, affecting product reliability and lifespan.

[0025] To address the aforementioned issues, this application provides a cable winding module that can arrange the rope independently of the surface condition of the cable drum itself. This effectively ensures that the lifting ropes are arranged tightly and orderly during the winding and unwinding process, effectively preventing knots from forming in the lifting ropes and significantly improving the stability and reliability of the cable winding module's operation.

[0026] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0027] Figure 1 This is a schematic diagram of the structure of the winding module shown in the embodiments of this application; Figure 2 This is another structural schematic diagram of the winding module shown in the embodiments of this application; Figure 3 This is another structural schematic diagram of the winding module shown in the embodiments of this application; Figure 4 This is another structural schematic diagram of the winding module shown in the embodiments of this application.

[0028] See Figures 1 to 4 The winding module of this application includes: a housing 210, at least two winding drums 220 and at least two lifting ropes 230 corresponding to the at least two winding drums 220.

[0029] The housing 210 has an installation cavity 211, and the bottom of the installation cavity 211 has a wire hole 212. The installation cavity 211 is mainly used to install components such as the cable reel 220 and the lifting rope 230.

[0030] The housing 210 can be composed of an upper housing and a lower housing. The upper housing and the lower housing can be detached and assembled by means of snap-fit.

[0031] The outer periphery of the cross-section of the mounting cavity 211 can be figure-eight shaped, thus forming two different mounting channels. This allows the cable reel 220 to be staggered between the two channels. The cable passage hole 212 is mainly used for the passage of the lifting rope 230.

[0032] Each cable pass hole 212 can be equipped with a ceramic cable guide ring, which can effectively improve the smoothness of the lifting rope passing through the cable pass hole 212.

[0033] At least two cable reels 220 are rotatably mounted in the mounting cavity 211. Each end of the cable reel 220 may be provided with a rotary bearing, and the cable reel 220 has a drive hole in the axial direction. A drive device drives the drive shaft passing through the drive hole to rotate, thereby realizing the rotation of the cable reel 220.

[0034] One end of each lifting rope 230 is fixed to the wall of a spool 220, and the other end passes through the thread hole 212 and is connected to a track structure of the curtain.

[0035] The mounting cavity 211 is also equipped with a rope arrangement structure 213 that is wound around one end of each spool 220 near the wire passage hole 212. The rope arrangement structure 213 is mainly used to guide the lifting rope 230 on the spool during winding and unwinding.

[0036] When the cable winding module of this application winds the lifting rope, the rope arrangement structure wound around the cable drum limits the lifting rope from both above and below the drum. This ensures that the coil formed by the lifting rope at the very end of the drum near the cable hole winds along a preset path. After each turn of the lifting rope is wound, the module automatically moves away from the rope arrangement structure on the drum and pushes the coil that was originally on the drum backward, thereby sorting the lifting ropes on the drum.

[0037] In some embodiments, the rope arrangement structure 213 may include at least an upper guide portion 2131 and a lower guide portion 2132. It is understood that the upper guide portion 2131 and the lower guide portion 2132 are two discontinuous, independent structures. The upper guide portion 2131 and the lower guide portion 2132 may be staggered and distributed above and below the corresponding reel 220. That is, the upper guide portion 2131 and the lower guide portion 2132 may be located on different sides of the reel 220. The upper guide portion 2131 and the lower guide portion 2132 form a rope arrangement channel surrounding the reel 220. It should be understood that the rope channel refers to the spatial area formed between the upper guide part 2131 and the lower guide part 2132 and wound around the drum 220. When the lifting rope 230 is wound and unwound on the drum 220, the rope channel is used to limit the lifting rope 230 on the outermost ring of the drum 220, so that the lifting rope 230 is arranged in a sorted manner along the axial direction of the drum.

[0038] The upper guide portion 2131 and the lower guide portion 2132 can be arc-shaped protrusions respectively provided on the upper and lower sides of the winding drum 220.

[0039] As an example, when the drum 220 rotates, the lifting rope 230 enters the housing 210 through the wire hole 212 and winds around the surface of the drum 220. The annular rope channel formed by the upper guide 2131 and the lower guide 2132 restricts the position of the coil of the lifting rope 230 near the end of its entry and exit from the drum 220 (i.e., closest to the wire hole 212). When the rope is continuously wound, the lifting rope 230 is forced to move away from the rope channel after each winding, thereby guiding the lifting rope 230 to be arranged axially along the drum 220. When the rope is continuously unwound, the upper guide 2131 and the lower guide 2132 block the lifting rope 230 so that the coil of the lifting rope 230 near the end of its entry and exit from the drum 220 is also restricted at the rope channel.

[0040] The upper guide portion 2131 is located on the side of the winding drum 220 near the wire passage hole 212, while the lower guide portion 2132 is located on the side of the winding drum 220 away from the wire passage hole 212. It can be understood that the lifting rope 230 enters and exits the winding module through the wire passage hole 212. The upper guide portion 2131 contacts the lifting rope 230 first from the side of the winding drum 220 near the wire passage hole 212, limiting the section of the lifting rope 230 furthest from the winding drum 220. The lower guide portion 2132 contacts the section of the rope initially wound onto the winding drum 220 from the side of the winding drum 220 away from the wire passage hole 212. This rope arrangement structure effectively ensures the proper positioning of the lifting rope 230.

[0041] In some embodiments, at least two cable reels can be arranged in parallel offsets along the same straight line. For example, at least two cable reels 220 are arranged axially parallel within the mounting cavity 211 but offset radially. By arranging at least two cable reels 220 in parallel offsets, the lifting ropes 230 corresponding to each reel can be distributed regularly along the same straight line without interfering with each other. It can be seen that by optimizing the distribution of the lifting ropes 230 corresponding to at least two cable reels 220, the internal space utilization of the cable winding module can be effectively improved, thereby making the overall size of the cable winding module more compact. Furthermore, due to the optimized distribution path of the lifting ropes 230, the arrangement of the lifting ropes 230 is more aesthetically pleasing and orderly, thus reducing the impact of messy rope distribution on the user experience of the product.

[0042] It should be understood that two parallel, staggered cable reels 220 can be driven to rotate using different drive shafts. That is, cable reels 220 that are not on the same straight line are driven by different drive shafts. Of course, cable reels 220 that are on the same straight line can be driven by the same drive shaft.

[0043] The above structure enables spatial layout optimization, drive separation control, and path constraint of the winding module. Furthermore, the synergistic effect of these functions effectively ensures the stability of the lifting rope as it rises and falls along the winding path.

[0044] In some embodiments, a partition plate 214 is provided within the mounting cavity 211, located between at least two cable reels 220. The partition plate 214 may consist of multiple partitions. The partition plate 214 divides the mounting cavity 211 into two independent and dedicated working channels, isolating the cable reels 220 that are misaligned between the two different working channels, further reducing interference between the different cable reels 220 during operation, and improving the stability of the cable winding module.

[0045] In some embodiments, the wire guide hole 212 and the partition plate 214 are distributed along the same straight line. It can be understood that the partition plate 214 is located between two different working channels of the winding drum 220, that is, the partition plate 214 is located in the area where the interference between different winding drums 220 is minimal. Distributing the wire guide hole 212 and the partition plate 214 along the same straight line can effectively avoid interference between the corresponding lifting ropes 230 of different winding drums 220 when entering and exiting the winding module, and can make full use of the space where the partition plate 214 is set, improving the space utilization rate of the product design. Furthermore, by limiting the distribution of the wire guide hole 212 along a straight line, the lifting path of the lifting rope can be effectively restricted, so that lifting ropes used for the same vertical area or the same side of the curtain can be raised and lowered through the wire guide hole 212 in the same distribution area.

[0046] In some embodiments, at least two pressure lines 215 corresponding to at least two cable reels 220 are also provided within the mounting cavity 211. Each pressure line 215 is arranged parallel to and above a cable reel 220. It is understood that the radial distance between each pressure line 215 and a cable reel 220 remains constant. The pressure lines 215 can be fixed to the inner wall of the housing 210. By providing pressure lines 215 corresponding to the cable reels 220, the pressure lines 215 further provide spatial constraint on the lifting rope 230 on the cable reel 220, thereby further preventing the lifting rope 230 from becoming loose.

[0047] In this configuration, the projected area of ​​each pressure line 215 on the corresponding drum 220 covers the corresponding rope arrangement structure on that drum. That is, the constraint space provided by each pressure line 215 can cover the rope arrangement channel formed by the upper guide portion 2131 and the lower guide portion 2132. In this way, the lifting rope is constrained by the spatial constraint of the pressure line 215 at the moment it enters or leaves the drum 220. It is easy to see that even after the track corresponding to the lifting rope is lifted, i.e., when the lifting rope loses its gravity, the lifting rope will not slacken when wound onto the drum 220 due to the combined effect of the pressure line 215 and the rope arrangement structure.

[0048] The pressure line 215 can be a strip structure extending axially along the winding drum 220.

[0049] In this embodiment, the winding module of this application has an independent rope arrangement structure wound around the corresponding position of the winding drum. The rope arrangement structure guides and regulates the winding path of the lifting rope on the winding drum, without relying on the surface condition of the winding drum itself. This effectively ensures that the lifting rope is arranged tightly and orderly during winding and unwinding, effectively preventing the lifting rope from getting knotted, avoiding rope arrangement failure caused by dust accumulation or wear on the surface of the winding drum, and effectively improving the stability and reliability of the winding module operation.

[0050] Corresponding to the aforementioned application function implementation device embodiments, this application also provides a winding mechanism and corresponding embodiments.

[0051] The winding mechanism of this application includes the winding module shown in the foregoing embodiments.

[0052] The winding mechanism of this application can be applied to electric curtains. By using a drive device to drive the winding module in the electric curtain, the lifting rope in the winding module can be raised and lowered, thereby controlling the curtain fabric of the electric curtain.

[0053] In this embodiment, the winding module has an independent rope arrangement structure wound around the corresponding position of the winding drum. The rope arrangement structure guides and regulates the winding path of the lifting rope on the winding drum, without relying on the surface condition of the winding drum itself. This effectively ensures that the lifting rope is tightly and orderly arranged during winding and unwinding, effectively preventing the lifting rope from becoming loose or knotted, avoiding rope arrangement failure caused by dust accumulation or wear on the surface of the winding drum, and effectively improving the stability and reliability of the winding module's operation.
