Description

Technical Field

[0001] This invention relates to an electric clothes drying rack, and more particularly to a clothes drying rack power system with an integrated wire rope protection mechanism. Background Technology

[0002] The wire rope power mechanism of a clothes drying rack is a crucial component, responsible for controlling the raising and lowering of the rack. This power mechanism includes a motor, a controller, and a winding reel. The motor drives the winding reel to rotate, thereby winding and unwinding the wire rope, thus controlling the raising and lowering of the clothes drying rack. For example, utility model patent CN210683034U discloses an electric clothes drying rack lifting motor, which includes a motor, a worm gear, and two worm wheels for winding the wire rope.

[0003] The invention patent application with publication number CN110004678A discloses a wire pressing mechanism for a stranded wire reel, which elastically presses the wire pressing component onto the stranded wire reel to avoid problems such as loosening and skipping of the wire rope.

[0004] In addition, the patents with authorization announcement number CN209906249U and application publication number CN110371878A also disclose a descent obstruction protection mechanism to ensure that the motor can stop running in time when the clothes rack encounters an obstacle during descent, thereby avoiding safety hazards.

[0005] The wire rope clamping device and the descent obstruction protection mechanism are two important components in a clothes drying rack, each performing different functions. The wire rope clamping device is mainly used to ensure that the wire rope remains neat during winding and unwinding, avoiding problems such as skipped lines, slack, or overlapping tangles. The descent obstruction protection mechanism, on the other hand, is used to stop the operation promptly when the clothes rack encounters an obstacle during descent, ensuring safety. If these two mechanisms are set up independently, the following disadvantages may exist:

[0006] 1. Independently configured components mean higher material and manufacturing costs, as each component requires separate design, manufacturing, and installation, increasing production costs. 2. When the two systems operate independently, any malfunction requires separate diagnosis and repair, increasing maintenance complexity and workload. 3. Independently configured mechanisms occupy more internal space, a problem particularly prominent in space-efficient clothes drying rack designs. Summary of the Invention

[0007] To address the aforementioned technical problems, this invention provides a clothes drying rack power system integrating a wire rope protection mechanism.

[0008] The core technical concept of this invention lies in achieving a compact layout and efficient operation of the wire rope protection mechanism in the power system of the clothes drying rack through integrated design, thereby improving safety, stability and maintenance efficiency, while reducing cost and space occupation, and meeting the needs of modern homes for high-performance clothes drying equipment.

[0009] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: a clothes drying rack power system integrating a wire rope protection mechanism, including a motor and a twisted wire reel device, wherein the twisted wire reel device includes a housing and two twisted wire reels, and the output shaft of the motor is connected to the two twisted wire reels through a transmission mechanism; each twisted wire reel is wound with and leads out a wire rope; each twisted wire reel is equipped with a wire rope protection mechanism.

[0010] The housing is provided with two windows corresponding to each strand reel; the wire rope on each strand reel can be led outward from the window;

[0011] The wire rope protection mechanism is installed at the window of the corresponding strand reel. The wire rope protection mechanism includes a rotating frame assembly, a micro switch, a first roller, and a second roller.

[0012] The rotating frame assembly includes a first rotating frame and a second rotating frame; the first roller is disposed at the waist position of the first rotating frame;

[0013] The first end of the first rotating frame is shaft-connected to the machine housing; the first end of the second rotating frame is shaft-connected to the second end of the first rotating frame; the second roller is shaft-connected to the second end of the second rotating frame.

[0014] The first end of the first rotating frame is equipped with a first torsion spring, and the first end of the second rotating frame is equipped with a second torsion spring;

[0015] Under the action of the second torsion spring, the second roller on the second rotating frame extends into the window and is always pressed against the surface of the corresponding stranded wire reel;

[0016] When the motor is running normally, a taut steel wire rope is drawn from the strand and pressed on the first roller. The pressure of the steel wire rope on the first roller overcomes the force of the first torsion spring, keeping the first end of the first rotating frame in the first position.

[0017] When the wire rope encounters resistance during descent, the slack wire rope is not pressed on the first roller. At this time, the force of the first torsion spring causes the first end of the first rotating frame to rotate from the first position to the second position, thereby triggering the micro switch of the first rotating frame to instruct the motor to stop running.

[0018] A further preferred embodiment of the present invention is as follows: a first shaft is provided on the housing, a first end of the first rotating frame is sleeved on the first shaft, a first torsion spring is sleeved on the first shaft, one end of the first torsion spring abuts against the limiting part of the housing, and the other end of the first torsion spring abuts against the first rotating frame.

[0019] A further preferred embodiment of the present invention is as follows: a second shaft is provided at the second end of the first rotating frame, the first end of the second rotating frame is sleeved on the second shaft, a second torsion spring is sleeved on the second shaft, the first end of the second torsion spring abuts against the first rotating frame, and the second end of the second torsion spring abuts against the second rotating frame.

[0020] A further preferred embodiment of the present invention is as follows: the first rotating frame includes two parallel first arms, and a first connecting plate and a second connecting plate are provided between the two first arms;

[0021] The first roller is located between the first connecting plate and the second connecting plate;

[0022] The outer side of the first connecting plate is used to trigger the micro switch; and the second end of the first torsion spring abuts against the inner side of the first connecting plate;

[0023] The first end of the second torsion spring abuts against the inner side of the second connecting plate;

[0024] The second rotating frame includes two parallel second arms, with a third connecting plate between the two second arms, and the second end of the second torsion spring abuts against the third connecting plate.

[0025] A further preferred embodiment of the present invention is that the micro switch is mounted on the outside of the housing via a mounting bracket.

[0026] A further preferred embodiment of the present invention is as follows: the first rotating frame includes a frame and a first support arm, the frame includes a second connecting plate and side plates on both sides, and the first roller is provided at the connection between the first support arm and the side plates;

[0027] The second rotating frame is pivotally connected to the lower end of the side plate via the second shaft.

[0028] A further preferred embodiment of the present invention is as follows: the second rotating frame includes the third connecting plate and a vertical plate disposed on the bottom wall of the third connecting plate, and the vertical plate is provided with a force-receiving hole for the end of the second torsion spring to pass through.

[0029] A further preferred embodiment of the present invention is as follows: the first arm includes a forearm segment and a rear arm segment, and the first connecting plate is disposed between the two forearm segments;

[0030] The rear arm section is inclined in the direction of the force exerted by the wire rope on the first roller.

[0031] A further preferred embodiment of the present invention is as follows: when the motor is running normally, the wire rope is in a taut state and applies pressure to the first roller, and the wire rope maintains a distance from the second roller.

[0032] A further preferred embodiment of the present invention is that the upper edge of the second connecting plate and the outer tangent of the outer curved wall corresponding to the position of the first roller are on the same straight line.

[0033] Compared with existing technologies, the advantages of this invention are: This technical solution effectively solves the multiple problems caused by independent components in traditional clothes drying racks through integration. The integrated wire rope protection mechanism reduces material and manufacturing costs, and the design and manufacturing process is simplified by sharing structural elements and mechanisms, such as the shared shaft of the rotating frame assembly and a uniformly configured torsion spring. This design not only reduces production costs but also improves space efficiency by reducing the space occupied inside the machine casing through centralized components.

[0034] When the wire rope encounters obstruction or breaks, the first torsion spring quickly pushes the first rotating frame, triggering a micro switch to immediately stop the motor and prevent potential damage. Simultaneously, the second torsion spring ensures that the second roller continuously applies pressure to the strand reel, maintaining the wire rope's neat alignment, preventing wire slippage, and enhancing the system's stability and reliability.

[0035] Furthermore, the integrated protection mechanism allows technicians to directly inspect and repair the integrated unit, reducing diagnostic time and improving maintenance efficiency. In addition, the coordinated operation of the integrated mechanism, such as the synchronous response of the first and second torsion springs, ensures a smooth transition under different tension states, enhancing the operational fluency and overall coordination of the clothes dryer.

[0036] By optimizing the spatial layout, such as through precisely positioned rotating frame components and shaft-connected rollers, clothes dryers have become more compact, meeting the space efficiency demands of modern homes. This technology not only enhances the user experience but also strengthens the product's market competitiveness, satisfying users' preferences for cost-effective, easy-to-maintain, and compactly designed clothes dryers.

[0045] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of the invention.

[0046] The clothes drying rack's power system integrates an innovative wire rope protection mechanism 200 to improve the safety and reliability of its operation. Figure 1 , Figure 2 as well as Figures 4 to 7 As shown, the power system 100 of the clothes drying rack consists of a core component motor 10 and a twisted coil device 20, which work together to achieve precise control of the clothes drying rack.

[0047] The motor 10 serves as the power source, connected to the transmission mechanism via its output shaft, thereby driving the two stranded reels 22 in the stranded reel device 20. This technology ensures smooth lifting and lowering of the clothes rack while reducing energy loss. The transmission mechanism guarantees precise torque transmission, ensuring stable operation of the clothes rack under different loads.

[0048] The cable reel device 20 consists of a robust housing 21 and two cable reels 22. The housing 21 not only provides the necessary mechanical support but also optimizes the internal space layout, making the entire system more compact. Each cable reel 22 is designed with a specific winding ratio and diameter to accommodate steel wire ropes s of different lengths and tensions. The steel wire ropes s are evenly wound on their respective cable reels 22, ensuring synchronization and uniformity during the raising and lowering of the clothes rack.

[0049] In addition, each strand 22 is equipped with a dedicated wire rope protection mechanism 200, which is crucial to the safety performance of the clothes drying rack, and will be described in detail below:

[0050] The housing 21 has two windows 23 corresponding to each strand reel, through which the wire rope s on each strand reel 22 can be led out. The housing 21 not only provides necessary protection and support for the strand reel 22 and other components, but also enables effective management and guidance of the wire rope s through the windows 23. The layout and size of the windows 23 are precisely calculated to ensure that the wire rope s can be led out directly and accurately from the strand reel 22.

[0051] The wire rope protection mechanism 200 is installed at the window 23 of the corresponding strand reel to ensure direct interaction and effective monitoring of the wire rope s. The wire rope protection mechanism 200 includes a rotating frame assembly 30, a micro switch 40, a first roller 51, and a second roller 52, forming a comprehensive protection system.

[0052] The rotating frame assembly 30 is the core component of the protection mechanism 200. It not only serves as a support structure but also allows the two rollers to flexibly and dynamically adjust their positions in different locations to accommodate varying tensions in the wire rope. This ensures stable contact between the rollers and the wire rope s while providing the necessary flexibility to adapt to changes in the wire rope s during winding and unwinding.

[0053] The micro switch 40 is a key component for safety monitoring. It is positioned along the path of the rotating frame assembly 30 to quickly detect and react to any abnormalities in the wire rope s. The micro switch 40 allows it to be triggered (physically via the rotating frame drive) when the tension of the wire rope s suddenly changes. If it encounters resistance or breaks, it immediately cuts off the power to the motor 10, stops the clothes rack from operating, and prevents potential injury or equipment damage.

[0054] Furthermore, under normal operating conditions, the first roller 51 maintains a stable downward pressure under the tension of the wire rope s. If the wire rope s breaks or encounters resistance causing the tension to disappear, the first roller 51 immediately moves upward under the push of the first torsion spring 61, triggering the micro switch 40 on a specific rotating frame wall, causing the motor 10 to stop operating and preventing potential damage. Simultaneously, in this preferred embodiment, the second roller 52, under the action of the second torsion spring 62, continuously applies pressure to the wire rope s wound on the strand spool 22. Even when the micro switch 40 is triggered and the motor 10 stops operating, it ensures that the wire rope s will not break, causing the strand spool 22 to haphazardly rewind the wire rope, thus maintaining the orderliness and safety of the system.

[0055] like Figure 6 and Figure 7As shown, the rotating frame assembly 30 includes a first rotating frame 31 and a second rotating frame 32. A first roller 51 is disposed at the waist position of the first rotating frame 31. This waist position refers to the area near the lower side of the first rotating frame 31. Placing the first roller 51 in this position allows it to be closer to the tension change point of the wire rope s, thereby improving the response speed and accuracy to changes in the state of the wire rope s.

[0056] The first end of the first rotating frame 31 is shaft-connected to the housing 21, and the first end of the second rotating frame 32 is shaft-connected to the second end of the first rotating frame 31; the second roller 52 is shaft-connected to the second end of the second rotating frame 32; the first rotating frame 31 and the second rotating frame 32 are stably connected through a precise shaft connection, ensuring the mechanical coordination and smooth operation of the entire assembly.

[0057] Furthermore, specifically, the first end of the first rotating frame 31 is securely connected to the housing 21 via a shaft connection, providing a solid fixing point and support foundation for the rotating frame assembly. Next, the first end of the second rotating frame 32 is shaft-connected to the second end of the first rotating frame 31, forming a series mechanical link. This arrangement allows the second rotating frame 32 to move in tandem with the first rotating frame 31, while maintaining structural compactness and operational consistency.

[0058] The rotating frame assembly 30 in the clothes drying rack's power system ingeniously utilizes torsion springs to achieve dynamic response and control of the tension of the steel wire rope s. Specifically, the first rotating frame 31 is equipped with a first torsion spring 61 at its first end, while the second rotating frame 32 is correspondingly equipped with a second torsion spring 62 at its first end. This configuration of torsion springs not only provides the necessary elastic potential energy to the rotating frame assembly 30 but also ensures that the rotating frame assembly can respond accurately and rapidly when the tension of the steel wire rope s changes.

[0059] During installation, under the action of the second torsion spring 62, the second roller 52 on the second rotating frame 32 can smoothly extend into the window 23 and maintain constant contact with the surface of the strand reel 22. This design not only ensures the neat arrangement of the wire rope s during winding and unwinding, but also avoids slack or misalignment.

[0060] When the motor 10 is running normally, the steel wire rope s led out by the strand 22 remains taut, and the clamping force it generates acts on the first roller 51. This pressure effectively counteracts the elastic force applied by the first torsion spring 61, ensuring that the first end of the first rotating frame 31 is stably maintained in the set first position.

[0061] When the steel wire rope S encounters resistance during its descent, the slack steel wire rope S is not pressed against the first roller 51. At this time, the force of the first torsion spring 61 causes the first end of the first rotating frame 31 to rotate from the first position to the second position, thereby triggering the micro switch 40 to instruct the motor 10 to stop running. This achieves an immediate response to abnormal conditions of the clothes drying rack, ensuring that the motor can quickly stop working when the steel wire rope S encounters an obstacle or breaks, thus avoiding possible further damage or safety risks. In this way, the power system of the clothes drying rack exhibits a high degree of intelligence and safety, providing users with a reliable protection measure and enhancing the stability and safety of the entire clothes drying rack operation.

[0062] Inside the power system of the clothes drying rack, the housing 21 is designed with a first shaft t1, which is a key support point for the rotating frame assembly. One end of the first rotating frame 31 is sleeved on the first shaft t1, ensuring the stability and accuracy of the rotating frame. At the same time, the first torsion spring 61 is also sleeved on the first shaft t1, with one end fixed to the limiting part r of the housing 21 and the other end connected to the first rotating frame 31, forming a mechanical structure that can accurately respond to changes in the tension of the wire rope s.

[0063] Furthermore, the other end of the first rotating frame 31 is equipped with a second shaft t2, and one end of the second rotating frame 32 is sleeved on the second shaft t2. The second torsion spring 62 is also sleeved on the second shaft t2, with one end connected to the first rotating frame 31 and the other end fixed to the second rotating frame 32. This configuration not only ensures coordinated movement between the two rotating frames but also, through the interaction of the torsion springs 61 and 62, enables sensitive monitoring and rapid response to changes in the tension of the wire rope s.

[0064] The aforementioned technical methods form a compact and efficient force transmission system, improving the overall rigidity of the machinery and enhancing the system's stability and durability. Furthermore, this layout saves space, simplifies the connection paths between components, and makes maintenance and repair more convenient. Shorter paths reduce potential failure points and also facilitate technicians in quickly locating and replacing worn or damaged parts.

[0065] Furthermore, the first rotating frame 31 consists of two parallel first arms c1, connected by a first connecting plate c2 and a second connecting plate c3, forming a stable structure. This technique not only enhances the rigidity of the rotating frame but also provides necessary support points for other components through reasonable space allocation. The first roller 51 is precisely positioned between the first connecting plate c2 and the second connecting plate c3, ensuring effective monitoring of the contact between the wire rope s and the roller during tension changes.

[0066] The outer surface of the first connecting plate c2 is designed as a key part for triggering the micro switch 40, which allows the first rotating frame 31 to respond quickly and trigger the safety mechanism when the wire rope s becomes abnormally slack. At the same time, the second end of the first torsion spring 61 is placed on the inner surface of the first connecting plate c2, providing stable elastic support for the rotating frame and ensuring its stability under normal working conditions and its rapid response capability under abnormal conditions.

[0067] The second rotating frame 32 also employs two parallel second arms d1, which are connected by a third connecting plate d2, forming a mechanical structure coordinated with the first rotating frame 31. The first and second ends of the second torsion spring 62 interact with the second connecting plate c3 and the third connecting plate d2, respectively, providing continuous elastic potential energy to the second rotating frame 32 and ensuring that the second roller 52 can continuously apply appropriate pressure to the wire rope s wound on the strand s reel 22.

[0068] The aforementioned technical measures not only demonstrate the high level of safety and reliability prioritized in the clothes drying rack's power system, but also achieve sensitive monitoring and rapid response to changes in the steel wire rope's state through precise mechanical layout and component interaction. These innovative mechanical designs enable the clothes drying rack to provide more stable and reliable lifting control while ensuring operational safety.

[0069] Furthermore, it should be noted that the micro switch 40 is mounted outside the housing 21 via a mounting bracket 70. The use of the mounting bracket 70 provides flexible mounting options for the micro switch 40, allowing the switch position to be adjusted according to actual needs to adapt to different installation requirements or optimize the force transmission path. Moreover, the micro switch 40's location outside the housing helps reduce the impact of electromagnetic interference or mechanical vibration from other components inside the housing on its performance, ensuring the stability and reliability of the switch.

[0070] Preferably, such as Figure 6 and Figure 7 As shown, the first rotating frame 31 includes a frame c5 and a first support arm c1. The frame c5 includes a second connecting plate c3 and side plates c4 on both sides, forming a robust frame structure that improves overall stability and durability. A first roller 51 is provided at the connection between the first support arm c1 and the side plate c4, maximizing the functionality of the rotating frame assembly within a limited space while ensuring the correct guidance of the wire rope. The second rotating frame 32 is connected to the lower end of the side plate c4 via a second shaft t2, simplifying the assembly process and making the installation of the rotating frame assembly quicker and more convenient.

[0071] The second rotating frame 32 includes a third connecting plate d2 and a vertical plate d3 disposed on the bottom wall of the third connecting plate d2. The vertical plate d3 has a force-bearing hole d4 through which the end of the second torsion spring 62 passes. The combination of the third connecting plate d2 and the vertical plate d3 provides a robust mounting platform for the torsion spring 62, enhancing the structural integrity and stability of the entire rotating frame.

[0072] The vertical plate d3, serving as a support structure for the torsion spring 62, provides a direct and effective force transmission path, allowing the spring's torque to be efficiently transmitted to the second rotating frame 32. This ensures that the end of the second torsion spring 62 can be precisely positioned and fixed, thereby guaranteeing the correct transmission and effective application of the spring force.

[0073] The first arm c1 includes a forearm section c11 and a rear arm section c12, with a first connecting plate c2 located between the two forearm sections c11. The rear arm section c12 is inclined in the direction in which the wire rope s exerts force on the first roller 51. The first arm c1 is composed of the forearm section c11 and the rear arm section c12, and the first connecting plate c2 is located between the two forearm sections c11. This layout enhances the overall stability and bending resistance of the structure.

[0074] The inclined design of the rear arm section c12 may increase the length of the lever arm, thereby generating a larger torque under the same torque and improving the mechanical advantages of the rotating frame assembly. In addition, the inclined rear arm section c12 can respond more quickly to the tension changes of the wire rope s and transmit the force to the first roller 51 in a timely manner, thereby quickly adjusting the power system of the clothes drying rack.

[0075] When the motor 10 is running normally, the wire rope s is taut and applies pressure to the first roller 51, while the wire rope s and the second roller 52 are kept at a distance to avoid mutual interference between the components and ensure the full performance of their respective functions.

[0076] Preferably, the upper edge of the second connecting plate c3 is collinear with the outer tangent of the outer curved wall corresponding to the position of the first roller 51. This ensures the alignment accuracy between the second connecting plate c3 and the first roller 51, helping to maintain the correct guidance and tension distribution of the wire rope s. By eliminating the gap between the second connecting plate c3 and the first roller 51, the swaying or vibration of the wire rope s during operation can be reduced, improving the stability of the system. The coordinated design of the second connecting plate c3 and the first roller 51 enhances the structural rigidity of the rotating frame assembly, reducing the possibility of deformation under high loads.
