Description

Technical Field

[0001] This utility model relates to the technical field of electric clothes drying rack drive devices, and in particular to a drive motor for clothes drying racks. Background Technology

[0002] Electric clothes drying racks have become widely used in homes due to their convenience. Most electric clothes drying racks include a lifting control device, which consists of a motor, a pull cord, and a cord reel. One end of the pull cord is connected to the clothes rod and wound around the cord reel. The motor drives the cord reel to rotate, causing it to wind or unwind the pull cord, thus raising or lowering the clothes rod. Existing drive motors often use a single output shaft to drive two cord reels for lifting. This motor output method places a greater load on the output shaft, making it prone to fluctuations in motor output, which in turn can cause fluctuations in the clothes drying rack's lifting process.

[0003] Chinese Patent Publication No. CN219730388U, published on September 22, 2023, discloses a lifting control device for an electric clothes drying rack and the electric clothes drying rack itself. The device includes a housing, a motor, two rope-winding wheels, and two pull ropes. Each pull rope corresponds to one of the two rope-winding wheels. One end of each pull rope is connected to and wound around a rope-winding wheel, while the other end forms a connecting end for connecting to the clothes drying rod of the electric clothes drying rack. The motor body is fixed to the housing, and both rope-winding wheels are pivotally connected to the housing. A transmission component is pivotally connected to the housing and connected to the motor's output shaft. The lifting control device also includes a magnetic ring, which is synchronously connected to the transmission component. A Hall sensor corresponding to the magnetic ring is installed on the housing, and the Hall sensor is connected to the motor via a signal. A drawback of this invention is that controlling two rope-winding wheels through the output shaft of a single motor can easily cause fluctuations in the motor's output. Utility Model Content

[0004] This invention aims to overcome the shortcomings of existing technologies where the output shaft of one motor controls two winding wheels, which can easily cause fluctuations in the motor output. It provides a drive motor for clothes racks that can improve the reliability of motor output.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A drive motor for a clothes drying rack includes:

[0007] Dual-axis motor;

[0008] Support frames are installed at both ends of the dual-axis motor;

[0009] A winding assembly is installed inside a support frame and is connected to the motor shaft of a dual-axis motor.

[0010] A limiting component, which is mounted on a support frame and corresponds to the winding component;

[0011] A protective shell, which is mounted on a support frame.

[0012] The dual-axis motor is housed within a protective casing. It can output power simultaneously from both ends and utilizes a flat, high-voltage dual-worm DC motor. This motor operates directly on a 220V DC power supply, offering significant performance advantages, particularly under rated load conditions: low current, low temperature rise, and minimal current fluctuation. This motor employs highly sensitive electrical components to further reduce electromagnetic interference, thereby ensuring the control sensitivity of the electric clothes drying rack. Furthermore, this motor uses Class F insulation materials and windings, and has passed 3C testing and obtained certification, further ensuring the electrical safety of the electric clothes drying rack. Support frames are installed at both ends of the dual-axis motor, and winding assemblies are mounted on these frames. The two output shafts of the dual-axis motor drive the winding assemblies on both sides of the support frame. The rotation of the winding assemblies winds up and unwinds the pull rope. A protective shell is installed on the support frame to protect the dual-axis motor. Limiting components are installed on the support frame corresponding to the winding assemblies. These limiting components restrict the winding assemblies, ensuring they stop when encountering resistance, thus protecting them. The dual-axis drive improves the stability of the drive, thereby enhancing the reliability of the motor output.

[0013] Preferably, the two ends of the dual-axis motor are connected to the support frames on both sides, and the support frames are provided with a winding cavity. A sealing cover is installed at one end of the opening of the winding cavity, and the sealing cover corresponds to the winding cavity. The winding assembly is installed in the winding cavity. The winding assembly includes a first rotating shaft, a second rotating shaft, and a winding shaft. Both ends of the dual-axis motor are provided with worm gears. One end of the worm gear is connected to the motor shaft of the dual-axis motor, and the other end of the worm gear passes through the support frame and is placed in the winding cavity. One end of the first rotating shaft is rotatably connected to the support frame, and the other end of the first rotating shaft is rotatably connected to the sealing cover. A worm wheel is installed on the first rotating shaft, and the worm gear meshes with the worm wheel. A gear is installed on one side of the worm wheel. One end of the second rotating shaft is rotatably connected to the support frame, and the other end of the second rotating shaft is rotatably connected to the sealing cover. The winding shaft is installed on the second rotating shaft, and a gear is installed on the winding shaft. The gear meshes with the gear. The dual-axis motor has its support frame fixed to its end face on both sides with screws. The output shaft of the dual-axis motor passes through the support frame and is placed inside the winding chamber. The dual-axis motor drives the worm gear to rotate. Through the meshing of the worm wheel and the worm gear, the worm gear drives the worm wheel in the winding chamber to rotate. The worm wheel drives the first rotating shaft to rotate together. The worm wheel drives the first gear on the first rotating shaft to rotate. Through the meshing of the first gear and the second gear, the first rotating shaft drives the second rotating shaft to rotate. The rotation of the second rotating shaft drives the winding shaft to rotate together, thereby realizing the winding and unwinding of the lifting rope. The winding chamber has an opening on one side to facilitate the installation of the internal structure. After installation, it is closed with a cover, which also supports the first and second rotating shafts. This design allows the winding shaft to rotate.

[0014] Preferably, the winding shaft is provided with a winding groove, which is threaded. The support frame is equipped with an inlet and outlet, which correspond to the winding shaft. The threaded winding groove on the winding shaft is used to wind up the pull rope. The pull rope is wound on the winding shaft and can be released from the inlet and outlet during the rotation of the winding shaft. The inlet and outlet correspond to the release end, reducing wear on the support frame caused by the pull rope. This design allows for the release of the pull rope.

[0015] Preferably, the limiting component includes a rotating plate and a micro switch. A rotating shaft is mounted on the support frame. The rotating plate is mounted on and rotatably connected to the rotating shaft. One end of the rotating plate has a wire hole corresponding to the inlet and outlet. A contact rod is installed in the wire hole. A lever is mounted on the other end of the rotating plate. The micro switch is mounted on the support frame and corresponds to the lever. A torsion spring is mounted on the rotating shaft. One end of the torsion spring is connected to the rotating shaft, and the other end of the torsion spring is connected to the rotating plate. The rotating plate of the limit assembly rotates on the support frame via a rotating shaft three. A wire hole is opened on one side of the rotating plate, corresponding to the inlet and outlet. After the pull rope is released from the inlet and outlet, it passes through the wire hole and comes into contact with the contact rod. The rotating plate rotates under the torque of the torsion spring on the rotating shaft three, and the rotating plate comes into contact with the pull rope. When the pull rope is released and the clothes rack descends, it is blocked, the pull rope is relaxed, and the pull rope contacts the contact rod. The rotating plate rotates under the drive of the torsion spring. The lever at the other end of the rotating plate contacts the micro switch. The micro switch sends an electrical signal to the controller to control the motor to shut off and stop the clothes rack from being released in time. This design can ensure that the clothes rack stops when it encounters an obstacle.

[0016] Preferably, the protective shell includes a base and a top cover. The base has a U-shaped cross-section and is connected to two support frames on both sides. A stabilizing plate is mounted on the base, with its two ends connected to the bottom surfaces of the support frames on both sides. The top cover also has a U-shaped cross-section and corresponds to the dual-axis motor. Locking blocks are installed on both sides of the top cover, and the support frames have locking slots. The top cover is detachably connected to the support frames on both sides through the engagement of the locking blocks and slots. The base of the protective shell connects to the support frames on both sides, ensuring the integrity of the drive motor. To improve stability, a stabilizing plate is installed on the base, connecting the support frames on both sides into a whole, ensuring stability during the winding and pulling of the rope. The top cover is installed on the upper end of the dual-axis motor, and it is snapped into the support frame through the engagement of the locking blocks and slots. This design protects the dual-axis motor and ensures the stability of the drive motor.

[0017] Preferably, the top cover is provided with a heat dissipation grid, and plugs are installed on both sides of the top cover. The support frame is provided with slots, and the plugs match the slots. One plug-in block is installed on one side of the top cover, and one plug-in groove is provided on the other side of the top cover. One plug-in block is installed on one side of the base, and one plug-in groove is provided on the other side of the base. The first plug-in block corresponds to the second plug-in groove, and the second plug-in block corresponds to the first plug-in groove. The heat dissipation grid on the top cover is used for heat dissipation. The top cover and the base are locked together by the engagement of the first plug-in groove and the second plug-in block, as well as the engagement of the second plug-in groove and the first plug-in block, facilitating quick connection between the top cover and the base. The plugs installed on the top cover allow the plugs on both sides to be inserted into the slots of the support frame during installation, limiting the position of the top cover. This design facilitates the connection between the top cover and the base.

[0018] Preferably, the support frame is provided with a wiring groove, and a limiting groove is installed on one side of the wiring groove. A connector is installed in the limiting groove of the support frame, and a sealing block is installed on the support frame, with the sealing block corresponding to the wiring groove. The support frame has a wiring groove, and the limiting groove in the wiring groove is used to install the connector. The connector installed in the wiring groove of one side of the support frame is connected to the controller, and the connector installed in the wiring groove of the other side of the support frame is connected to the power supply to power the dual-axis motor. The open side of the wiring groove is sealed by the sealing block, and the connector is connected to the dual-axis motor through a wire. This design allows for electrical connection with the dual-axis motor.

[0019] The beneficial effects of this utility model are: it can improve the reliability of motor output, drive the winding shaft to rotate, release the pull rope, ensure that the clothes rack stops when it encounters an obstacle, ensure the stability of the drive motor, facilitate the connection between the top cover and the base, and can be electrically connected to a dual-axis motor.

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] The winding shaft 33 is provided with a winding groove 36, which is threaded. The support frame 2 is equipped with an inlet and outlet 23, which correspond to the winding shaft 33.

[0036] like Figure 5 As shown, the limiting assembly 4 includes a rotating plate 41 and a micro switch 42. A rotating shaft 24 is mounted on the support frame 2. The rotating plate 41 is mounted on the rotating shaft 24 and rotatably connected to the rotating shaft 24. One end of the rotating plate 41 is provided with a wire hole 43, which corresponds to the inlet and outlet 23. A contact rod 44 is installed in the wire hole 43. A lever 45 is installed on the other end of the rotating plate 41. The micro switch 42 is mounted on the support frame 2 and corresponds to the lever 45. A torsion spring 46 is installed on the rotating shaft 24. One end of the torsion spring 46 is connected to the rotating shaft 24, and the other end of the torsion spring 46 is connected to the rotating plate 41.

[0037] like Figure 6 As shown, the protective shell 5 includes a base 51 and a top cover 52. The two sides of the base 51 are connected to two support frames 2 respectively. The cross-sectional shape of the base 51 is U-shaped. A stabilizing plate 53 is provided on the base 51. The two ends of the stabilizing plate 53 are connected to the bottom surfaces of the support frames 2 on both sides respectively. The cross-sectional shape of the top cover 52 is U-shaped. The top cover 52 corresponds to the dual-axis motor 1. The two sides of the top cover 52 are equipped with locking blocks 54. The support frame 2 is provided with a locking groove 25. The top cover 52 is detachably connected to the support frames 2 on both sides through the cooperation of the locking blocks 54 and the locking groove 25.

[0038] The top cover 52 is provided with a heat dissipation grid 55. Both sides of the top cover 52 are equipped with plugs 56. The support frame 2 is provided with a slot 57. The plugs 56 match the slots 57. One side of the top cover 52 is equipped with a first plug block 521, and the other side of the top cover 52 is equipped with a first plug groove 522.

[0041] After the clothes rack is pulled out through the inlet / outlet 23 by the pull rope, the pull rope contacts the contact rod 44 of the rotating plate 41. The position of the rotating plate 41 is maintained by the contact between the pull rope and the contact rod 44. When the clothes rack is blocked by the pull rope, the pull rope is released. At this time, the pull rope is lowered by the squeezing force of the contact rod 44. Then, the rotating plate 41 rotates under the torque of the torsion spring 46. The rotation of the rotating plate 41 drives the paddle 45 to contact the micro switch 42, thereby controlling the dual-axis motor 1 to stop through the electrical signal of the micro switch 42.
