Description

Technical Field

[0001] This invention relates to the field of electric clothes drying rack drive technology, specifically a novel electric clothes drying rack drive assembly. Background Technology

[0002] The drive assembly of an electric clothes drying rack, after the power is turned on, uses a motor and a reducer to move the clothes drying rack up and down. A limit switch sets the starting and ending positions of the clothes drying rack, while the controller manages the rising, falling, and stopping actions, thus achieving intelligent operation of the clothes drying rack's lifting and lowering.

[0003] Electric clothes drying rack drive assemblies typically use single-shaft or dual-shaft motors. To achieve motor shaft commutation and calculate the number of rotations, commutators, carbon brushes, Hall effect sensors, and magnetic rings are installed at corresponding positions on the motor drive. The winding wheel assembly within existing electric clothes drying rack drive assemblies has a complex structure, which can lead to the clothes drying wire getting stuck during use. Summary of the Invention

[0004] The purpose of this invention is to provide a novel electric clothes drying rack drive assembly to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a novel electric clothes drying rack drive assembly, comprising a dual-shaft drive motor, a first winding wheel assembly, and a second winding wheel assembly. The first and second winding wheel assemblies are respectively mounted on both ends of the dual-shaft drive motor. Each of the first and second winding wheel assemblies includes a gear guard, a rear cover, a large gear, a clothes drying wire rope drum, a rotating shaft, and a gear pair. Two rotating shafts are mounted on the rear cover, and a large gear and a gear pair are rotatably mounted on each shaft. The clothes drying wire rope drum is fixed to the middle of the large gear. The gear guard is bolted to the side of the rear cover, and the large gear, clothes drying wire rope drum, and gear pair are all disposed inside the gear guard. The large gear meshes with one side of the gear pair, and a worm gear meshes with the other side of the gear pair. The end of the worm gear furthest from the gear pair is fixedly connected to the output end of the dual-shaft drive motor.

[0006] Both winding wheel assembly one and winding wheel assembly two employ a transmission system between a large gear and a gear pair to drive the clothesline steel wire rope drum to rotate, thereby achieving the raising and lowering of the clothesline steel wire rope. The worm gear and dual-shaft drive motor are used to drive the rotation of the gear pair. The overall drive structure is simple, making assembly quick and convenient, and preventing the clothesline steel wire rope from getting stuck.

[0007] A connecting post is fixedly connected to the top of the gear protective cover. A limit clip and a retaining spring are sleeved on the surface of the connecting post, and one end of the retaining spring abuts against the gear protective cover.

[0008] One end of the limiting clip has a guide opening, and a guide cylinder is rotatably connected to the bottom of the guide opening. The guide opening is used to guide the clothesline wire rope. The retaining spring and the limiting clip serve to buffer and limit movement.

[0009] The bottom of the dual-axis drive motor is also equipped with a mounting cover. The two ends of the mounting cover are fixedly connected to the first winding wheel assembly and the second winding wheel assembly by bolts, respectively. The surface of the mounting cover is provided with mounting holes. The mounting cover is used to install the electric clothes drying rack drive assembly.

[0010] A limiting bolt is inserted at one end of the gear protective cover near the dual-axis drive motor. One end of the limiting bolt is threaded into a fixing hole, which is located at both ends of the dual-axis drive motor. A bearing is fitted at the connection between the worm gear and the dual-axis drive motor. The limiting bolt and fixing hole are used for the assembly of the gear protective cover and the dual-axis drive motor.

[0011] The surface of the clothes-drying wire rope spool is provided with threaded grooves, which match the clothes-drying wire rope, and the clothes-drying wire rope is wound inside the threaded grooves. The threaded grooves are used to wind the clothes-drying wire rope.

[0012] A commutator and a magnetic ring are fixed to the two output shafts of the dual-axis drive motor, respectively; carbon brushes capable of sliding contact with the commutator are installed on the first winding wheel assembly; and Hall effect sensors capable of sensing the magnetic rings are installed on the second winding wheel assembly. The commutator is used to adjust the direction of the dual-axis drive motor.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The design of the first and second winding wheel assemblies, employing a transmission system between a large gear and a gear pair, effectively simplifies the drive structure, making overall assembly quicker and more convenient. Simultaneously, the coordinated arrangement of the large gear, gear pair, and worm gear effectively prevents the clothesline wire rope from getting stuck, improving the stability and reliability of the clothes rack. Furthermore, the included guide opening, guide drum, snap ring, and limiters not only guide the clothesline wire rope but also provide cushioning and limiting functions. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0022] Please see Figure 1-5 This invention provides a novel electric clothes drying rack drive assembly, including a dual-shaft drive motor 1, a first winding wheel assembly 5, and a second winding wheel assembly 8. The first winding wheel assembly 5 and the second winding wheel assembly 8 are respectively mounted at both ends of the dual-shaft drive motor 1. Both the first winding wheel assembly 5 and the second winding wheel assembly 8 include a gear protective cover 6, a rear cover 10, a large gear 13, a clothes drying wire rope drum 14, a rotating shaft 15, and a gear pair 16. Two rotating shafts 15 are mounted on the rear cover 10, and each rotating shaft 15 rotates... The device is equipped with a large gear 13 and a gear pair 16. A clothes drying wire rope drum 14 is fixed in the middle of the large gear 13. A gear protective cover 6 is bolted to the side of the rear cover 10. The large gear 13, the clothes drying wire rope drum 14, and the gear pair 16 are all located inside the gear protective cover 6. The large gear 13 meshes with one side of the gear pair 16, and a worm gear 12 is meshed with the other side of the gear pair 16. The end of the worm gear 12 away from the gear pair 16 is fixedly connected to the output end of the dual-shaft drive motor 1.

[0023] Specifically, both the first winding wheel assembly 5 and the second winding wheel assembly 8 utilize the transmission between the large gear 13 and the gear pair 16 to drive the clothesline steel wire rope drum 14 to rotate, thereby achieving the raising and lowering of the clothesline steel wire rope. The worm gear 12 and the dual-shaft drive motor 1 are configured to drive the rotation of the gear pair 16. The overall drive structure is simple, making assembly quick and convenient, and preventing the clothesline steel wire rope from getting stuck.

[0024] A connecting post 17 is fixedly connected to the top of the gear protective cover 6. A limit clip 3 and a retaining spring 2 are sleeved on the surface of the connecting post 17. One end of the retaining spring 2 abuts against the gear protective cover 6.

[0025] Specifically, one end of the retaining spring 2 abuts against the gear protective cover 6, and one side of the retaining spring 2 is fixedly connected to the limiting clip 3. Thus, when the retaining spring 2 receives pressure, it will provide a reverse force to the limiting clip 3, causing the limiting clip 3 to lock.

[0026] One end of the limiting clip 3 is provided with a guide port 19, and the bottom of the guide port 19 is rotatably connected to a guide cylinder 4.

[0027] Specifically, the guide drum 4 allows the clothesline wire rope to move more smoothly, reducing friction and further improving the stability and lifespan of the clothes rack. At the same time, the rotating connection design of the guide drum 4 ensures flexible movement of the clothesline wire rope within the guide opening 19, preventing jamming or wear.

[0028] The bottom of the dual-axis drive motor 1 is also provided with a mounting cover 7. The two ends of the mounting cover 7 are fixedly connected to the first winding wheel assembly 5 and the second winding wheel assembly 8 respectively by bolts. The surface of the mounting cover 7 is provided with mounting holes 9.

[0029] Specifically, the mounting cover 7 not only provides protection for the entire drive assembly but also facilitates its connection with other parts of the electric clothes drying rack. The mounting hole 9 makes the installation process simpler and faster, improving assembly efficiency.

[0030] A limiting bolt 18 is inserted at one end of the gear protective cover 6 near the dual-axis drive motor 1. One end of the limiting bolt 18 is threaded to the fixing hole 20, and the fixing hole 20 is opened at both ends of the dual-axis drive motor 1. A bearing 11 is sleeved at the connection between the worm gear 12 and the dual-axis drive motor 1.

[0031] Specifically, the matching arrangement of the limiting bolt 18 and the fixing hole 20 ensures a stable connection between the gear guard 6 and the dual-axis drive motor 1, preventing malfunctions caused by loosening. At the same time, the use of the bearing 11 reduces friction between the worm gear 12 and the dual-axis drive motor 1, extending its service life.

[0032] Under the action of the dual-shaft drive motor 1, the worm gear 12 rotates, which in turn drives the gear pair 16 to rotate. Due to the meshing relationship between the gear pair 16 and the large gear 13, the large gear 13 also rotates, driving the clothes drying wire rope drum 14 to rotate. This design not only simplifies the transmission structure but also improves the transmission efficiency, making the raising and lowering of the clothes rack more stable and faster.

[0033] The surface of the clothes drying wire rope spool 14 is provided with a threaded groove, and the threaded groove matches the clothes drying wire rope, with the clothes drying wire rope wound inside the threaded groove.

[0034] A commutator and a magnetic ring are fixed on the two output shafts of the dual-shaft drive motor 1, respectively; a carbon brush capable of sliding contact with the commutator is installed on the winding wheel assembly 5; a Hall element capable of sensing the magnetic ring is installed on the winding wheel assembly 8.

[0035] In practical use, the dual-shaft drive motor 1 starts, and its output shaft drives the worm gear 12 to rotate. The worm gear 12 meshes with the gear pair 16, thereby driving the gear pair 16 to rotate. Due to the meshing relationship between the gear pair 16 and the large gear 13, the large gear 13 also rotates. The clothes drying wire rope drum 14 fixed in the middle of the large gear 13 rotates synchronously, realizing the winding and unwinding of the clothes drying wire rope, thereby controlling the raising and lowering of the clothes rack.

[0036] Meanwhile, a commutator fixed on one output shaft of the dual-axis drive motor 1 slides in contact with the carbon brushes on the winding wheel assembly 5 to adjust the motor's direction. A magnetic ring on the other output shaft is sensed by a Hall element on the winding wheel assembly 8 to calculate the number of motor rotations, ensuring precise control of the clothes rack's lifting and lowering.

[0037] Furthermore, the entire drive assembly has a compact structure and is easy and quick to assemble. The gear guard 6 and rear cover 10 not only protect the internal transmission mechanism but also improve the overall aesthetics and safety. The design of the guide port 19, guide drum 4, snap ring 2, and limit clip 3 further enhances the guiding and stability of the clothesline wire rope, preventing jamming or wear and extending its service life.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
