[0038] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] Specific Implementation Example 1: Please refer to... Figures 1-10 A clothes drying rack power system wiring device includes:

[0040] A motor assembly, wherein a rope winding mechanism is connected to the output shaft of the motor assembly;

[0041] It is understandable that, such as Figure 1As shown, the power system wiring device described in this solution is located inside the main unit of the clothes drying rack, the motor assembly is installed inside the main unit 11, and two steel wire ropes 17 extend below the main unit 11 to suspend the drying rod 50 for drying purposes. The motor assembly is a conventional servo motor, including a motor 24, which is located at the side end of the rope winding mechanism. Therefore, the combination of the rope winding mechanism and the motor 24 is distributed along the length direction. This allows for more efficient use of the space inside the main unit 11.

[0042] It is worth noting that the winding mechanism is surrounded and fixed by the upper shell 12 and the lower shell 13.

[0043] The rope winding mechanism includes a roller section, on which a steel wire rope 17 is wound around the outer circular surface. A wire laying mechanism is connected to the roller section. The wire laying mechanism is connected to the roller section and the two operate synchronously to precisely arrange and wind the steel wire rope 17 onto the outer end surface of the roller section.

[0044] The cable laying mechanism includes a drive shaft, which is arranged parallel to the drum section. Two tracks are provided on the drive shaft, and the transmission directions of the two tracks are respectively towards the two ends of the drum section. A groove is provided at the top of the cable laying mechanism to accommodate the wire rope 17, and the wire rope 17 slides in the groove. Inclined abutment surfaces are provided at both ends of the drive shaft.

[0045] The cable laying mechanism also includes a reversing member, which can drive unidirectionally along any of the tracks and change direction by contacting the abutment surface at the drive end of any track, and switch to another track.

[0046] It is worth noting that the function of the aforementioned drive shaft is to drive the wire laying mechanism to move along any track. As the drum rotates and the wire laying mechanism moves, the wire rope 17 is wound around the outer surface of the drum in close contact with each other. When the wire laying mechanism is wound to the end, it means that the outer surface of the drum has been fully wound with one layer of wire rope 17. The abutment surface provided at the end of the drive shaft is used to contact the reversing member and cause the reversing member to turn to another track. At this point, the wire laying mechanism changes direction to continue winding the wire rope 17 on the drum for a second layer.

[0047] The purpose of this arrangement is to precisely arrange the wire ropes 17 so that the wire ropes 17 on any layer are tightly attached to each other, preventing them from interfering with each other and getting tangled. Through the configuration of the drive shaft and the design of its bidirectional track, multiple layers of wire ropes 17 can be wound around the surface of the drum section and stored in an orderly manner without affecting each other, greatly increasing the drum section's capacity to store the wire ropes 17.

[0048] The drive shaft includes a guide shaft 15, and the two tracks each include a first spiral groove 45 and a second spiral groove 46. The first spiral groove 45 and the second spiral groove 46 are spiral grooves arranged on the outer circular surface of the guide shaft 15.

[0049] The first spiral groove 45 and the second spiral groove 46 have opposite spiral directions and are arranged to cross each other; the length of the first spiral groove 45 / second spiral groove 46 is the same as the length of the roller portion.

[0050] like Figure 5 As shown, it can be understood that the first spiral groove 45 and the second spiral groove 46 are arranged in opposite transmission directions and are interconnected with each other. However, the range of the connection between the two tracks is smaller than the volume of the circulation plate 41. Therefore, when the circulation plate 41 is driven on one track, it will not extend into the other track and cause interference.

[0051] The roller section includes a drum 14.

[0052] The lengths of the first spiral groove 45 and the second spiral groove 46 are the same as those of the drum 14. Therefore, when the cable laying mechanism moves along the first spiral groove 45 or the second spiral groove 46 to the end, it indicates that the drum 14 is completely covered with a layer of wire rope 17. Generally, the length of the drum 14 can be slightly greater than the length of the first spiral groove 45 or the second spiral groove 46, but the effect is not as good as having the same length, especially when the wire rope 17 has multiple layers of winding, the difference in effect is more obvious.

[0053] The wiring mechanism includes a conductor block 16, in which a through transmission cavity 42 is provided. The guide shaft 15 extends into the transmission cavity 42. A mounting cavity 44 is provided on the lower side of the transmission cavity 42. The commutator is installed in the mounting cavity 44, and the top of the commutator extends into the transmission cavity 42.

[0054] like Figure 4 It is understood that the aforementioned guide block 16 is a single unit, integrating a groove for connecting to the wire rope 17 and a reversing component for transmission with the guide shaft 15. A groove 43 is formed at the top of the guide block 16. The groove 43 is an upward-opening groove that extends through both ends, allowing the wire rope 17 to pass through and slide within it. A transmission cavity 42 is provided within the guide block 16, located below the groove 43. The transmission cavity 42 extends through the entire structure, allowing the guide shaft 15 to pass through. A mounting cavity 44 is connected to the lower side of the transmission cavity 42 to accommodate the reversing component. The top of the reversing component, i.e., the component used for reversing, extends into the transmission cavity 42 and is driven by the two tracks.

[0055] The reversing component includes a guide seat 27, which can rotate within the mounting cavity 44. The top of the guide seat 27 is provided with an arc-shaped circulation plate 41, which can extend into any of the tracks and move to any end position of the track as the guide shaft 15 rotates. Then, it contacts the abutment surface, flips over, and extends into another track.

[0056] like Figure 5 As shown, it can be understood that the guide seat 27 is the base of the circulation plate 41, used to support the circulation plate 41 to slide up and down within the mounting cavity 44. The circulation plate 41 has an arc-shaped plate structure, extending into the first spiral groove 45 or the second spiral groove 46 with a small volume, and switching between the two.

[0057] As described above, the contact surface includes a reversing surface 49, which is located at the two ends of the first spiral groove 45 and the second spiral groove 46, and is arranged with an inclined end face. When the circulating plate 41 contacts the reversing surface 49, it will swing and turn due to the contact, thereby extending from one track to another for reversal. At this time, the guide block 16 moves in the opposite direction. (The guide shaft 15 is a conventional bidirectional screw, also known as a reciprocating screw, etc.)

[0058] The diameter of the circulation plate 41 is between the diameter of the track and the diameter of the guide shaft 15.

[0059] It is understandable that, since the diameter or curvature of the circulation plate 41 is between the diameter of the track and the diameter of the guide shaft 15, the circulation plate 41 will not interfere or collide when it is driven in the first spiral groove 45 or the second spiral groove 46; and the circulation plate 41 can switch tracks more smoothly.

[0060] A spring 28 is installed inside the mounting cavity 44. One end of the spring 28 is fixed to the inside of the mounting cavity 44, and the other end of the spring 28 abuts against the guide seat 27.

[0061] like Figure 4 It is understood that the mounting cavity 44 contains components for supporting the guide seat 27, including a spring 28 and a sealing block 29. The sealing block 29 is fixedly disposed at the bottom of the mounting cavity 44 to close the mounting cavity 44. The spring 28 is disposed between the guide seat 27 and the sealing block 29, with one end abutting against the sealing block 29 and the other end abutting against the guide seat 27, so that its elastic release end abuts against the guide seat 27, thereby driving the circulating plate 41 to move stably and firmly within the track.

[0062] A first speed regulating mechanism is connected between the motor assembly and the rope winding mechanism. This first speed regulating mechanism has two speed levels, including a first gear 23 and a second gear 47. The first gear 23 is connected to the output end of the motor assembly, and the first gear 23 and the second gear 47 are coaxially arranged. The second gear 47 serves as the output end of the first speed regulating mechanism and is connected to the rope winding mechanism. The transmission ratio of the second gear 47 is less than the transmission ratio of the first gear 23.

[0063] like Figure 6 , 7 As shown, it can be understood that the first gear 23 and the second gear 47 are coaxially arranged. The first gear 23 is directly connected to the worm gear 48 for a first-stage reduction. The transmission ratio of the coaxial second gear 47 is less than that of the first gear 23. The second gear 47 is connected to the main gear 21 for a second-stage reduction.

[0064] The winding mechanism is provided with at least one, including a main gear 21, which is connected to the second gear 47 in a transmission manner. The roller part is coaxially arranged with the main gear 21. The main gear 21 is also coaxially arranged with a third gear 31, which is connected to the cable laying mechanism.

[0065] It is understandable that the roller section, including the drum 14, the main gear 21, and the drum 14, can be coaxially connected or directly installed and fixed, but coaxiality must be maintained. Figure 7 As shown, the drum 14, main gear 21 and third gear 31 are coaxially arranged, which ensures high transmission efficiency and makes the internal structure simpler.

[0066] A second speed regulating mechanism is connected between the third gear 31 and the wiring mechanism. The second speed regulating mechanism includes a secondary gear 22. The third gear 31 and the secondary gear 22 are connected by a speed regulating gear. The secondary gear 22 is coaxially arranged with the transmission shaft.

[0067] It is understandable that, such as Figure 7 As shown, an intermediate gear 30 is also provided between the secondary gear 22 and the third gear 31. The intermediate gear 30 is used for reversing and speed regulation and is a conventional idler gear speed regulation gear structure.

[0068] It is worth noting that the secondary gear 22 provides power for the rotation of the guide shaft 15 after speed adjustment. The user can adjust the speed at which the guide block 16 moves when the guide shaft 15 rotates to match the speed at which the drum 14 winds the wire rope 17.

[0069] Working principle: In order to solve the problems of insufficient capacity of the drum 14 to hold the wire rope 17, as well as the possible problems of winding, tangling or jamming of the wire rope 17 when the drum 14 holds the wire rope 17, a wire arrangement mechanism is provided that can precisely arrange the wire rope 17 while the drum 14 winds the wire rope 17, and further increase the amount of wire rope 17 that can be wound.

[0070] After the user starts the motor 24, the power directly drives the worm gear 48 to rotate. Through the transmission of the worm gear 48 and the first gear 23, the second gear 47 and the main gear 21, the drum 14 is driven to roll to pull the wire rope 17 to wind and collect on the outer surface of the drum 14. At the same time, since there are two main gears 21, the two main gears 21 mesh with each other and rotate to drive the two drums 14 to rotate in opposite directions. This allows the wire rope 17 in both directions to be wound and collected simultaneously and synchronously, further increasing the amount of wire rope 17 that can be collected.

[0071] Depend on Figure 8 As shown, when the main gear 21 rotates, it drives the guide shaft 15 to rotate through the transmission of the third gear 31, the intermediate gear 30, and the auxiliary gear 22. When the guide shaft 15 rotates, it drives the guide block 16 to move away from the auxiliary gear 22 through the sliding of the circulation plate 41 in the second spiral groove 46. At this time, the wire groove 43 drives the wire rope 17 to maintain a perpendicular state with the drum 14 so that the wire rope 17 can be collected by the rotation of the drum 14.

[0072] like Figure 9 As shown, when the wire block 16 moves to the end of the second spiral groove 46 away from the auxiliary gear 22, a layer of steel wire rope 17 is already tightly wound on the outer surface of the drum 14.

[0073] like Figure 10 As shown, at this time, through the contact between the circulation plate 41 and the reversing surface 49, the circulation plate 41 is driven to rotate and move into the first spiral groove 45. At this time, the guide shaft 15 continues to rotate, causing the wire block 16 to move towards the side closer to the secondary gear 22. At this point, the drum 14 begins to wind the second layer of steel wire rope 17.

[0074] Understandably, by analogy, users can flexibly wind the third and fourth layers of wire rope 17 as needed, which greatly increases the amount of wire rope 17 that the drum 14 can hold.

[0075] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description.
