Description

Lifting clothes rod device and wardrobe

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on January 18, 2024, with application number 202410073459.8 and invention name “A lifting clothes rod device and wardrobe”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The embodiments of the present application relate to the technical field of smart home appliances, for example, to a lifting clothes rod device and a wardrobe. Background Art

[0003] In order to facilitate users to hang and take off clothes, and to effectively improve users' comfort and satisfaction, most of the relevant wardrobes are equipped with electric lifting clothes rod equipment.

[0004] The electric lifting rod system consists of a U-shaped rod and a drive box mounted on the side panel of the wardrobe. The middle section of the U-shaped rod serves as a clothes hanger (for hanging clothes / hangers), while the ends are swing arms, the base of which is mounted on the drive box. The drive box houses a motor drive unit and a spring buffer. Driven by the motor drive unit, the U-shaped rod automatically rises and falls.

[0005] To balance the support forces of the two swing arms, electric clothes-lift systems typically feature two drive motors. To maintain synchronization, encoders are also required for synchronization calibration, leading to higher costs for the electric clothes-lift system. The encoders are also typically installed within the drive box, resulting in a larger and more complex drive box. The two drive boxes also occupy more cabinet space, reducing the cabinet's effective storage space. Summary of the Invention

[0006] Based on this, an embodiment of the present application provides a lifting clothes rod device, which solves the problems of related electric lifting clothes rod equipment such as high cost, poor synchronization, the need for encoder adjustment, and large space occupation.

[0007] In order to achieve the above objectives, the technical solutions adopted in this application are:

[0008] A lifting clothes rod device, comprising a driving mechanism, a force transmission assembly, a lifting mechanism, a turntable assembly, a turntable connecting rod, and a clothes rod assembly;

[0009] The driving mechanism is drivingly connected to the force transmission component and is used to drive the force transmission component to rotate;

[0010] The two ends of the force transmission assembly are respectively drivingly connected to the first end of a lifting mechanism, and the second end of each lifting mechanism is rotatably connected to a turntable assembly through a turntable connecting rod;

[0011] The clothes rod assembly includes a clothes hanging rod and two swing rods, the two ends of the clothes hanging rod are respectively connected to the first end of the swing rod, and the second end of the swing rod is rotatably connected to the turntable assembly;

[0012] When the driving mechanism drives the force transmission assembly to rotate, the force transmission assembly is linked to the two lifting mechanisms to operate; the operation of the lifting mechanism drives the turntable assembly to rotate along its axis; during the rotation of the turntable assembly along its axis, the rocker arm is driven to rotate along the axis of the turntable assembly; the rotation of the two rocker arms links the clothes hanging rod to rise and fall.

[0013] Thus, the lifting clothes rod device of the embodiment of the present application is connected to the force transmission assembly through a driving mechanism, so that the driving mechanism can drive the force transmission assembly to operate; the two ends of the force transmission assembly are respectively connected to the lifting mechanism, so that when the driving mechanism drives the force transmission rod to rotate, the force transmission rod is linked to the operation of the two lifting mechanisms; the operation of the lifting mechanism drives the turntable assembly to rotate along its axis; during the process of the turntable assembly rotating along its axis, the rocker arm is driven to rotate along the axis of the turntable assembly; the rotation of the two rocker arms is linked to the lifting and rotation of the clothes hanging rod. Compared with the related electric lifting clothes rod equipment, the lifting clothes rod device of the embodiment of the present application can realize the function of driving the clothes rod assembly to be lifted, lowered and rotated by a single driving mechanism, without the need for two driving mechanisms to drive the clothes rod assembly to be lifted, lowered and flipped, effectively reducing the cost of the equipment and also reducing the space occupied by the driving mechanism. In addition, by using the force transmission component as the linkage component between the driving mechanism and the two lifting mechanisms, the torque can be synchronously transmitted to the two lifting mechanisms through the force transmission component, and the two lifting mechanisms can be driven to operate synchronously. In this way, there is no need to adjust through the encoder to ensure that the two lifting mechanisms can synchronously drive the clothes rod assembly to lift and rotate, and the clothes rod assembly can rotate smoothly, effectively avoiding the undesirable phenomenon of the clothes rod assembly flipping and jamming.

Therefore, the embodiment of the present application transmits torque synchronously to the two transmission assemblies through the force transmission assembly, and synchronously drives the screw assembly to perform lifting operations through the two transmission assemblies, so that the two screw assemblies synchronously drive the turntable assembly to rotate respectively through the turntable connecting rod, ensuring that the two turntable assemblies can synchronously drive the two rocker arms to swing.

[0015] As an optional embodiment, the transmission assembly includes a gear box, a transmission gear, and a screw drive gear. The gear box is installed in the lifting installation box. The transmission gear and the screw drive gear are rotatably arranged in the gear box. The transmission gear is meshed with the screw drive gear, and the screw drive gear is driven by the screw assembly.

Therefore, the embodiment of the present application is driven by the two ends of the force transmission assembly and the two transmission gears, so that the force transmission assembly can synchronously transmit the torque to the two transmission gears, and then drive the screw drive gear to rotate through the two transmission gears, and synchronously drive the screw assembly to perform the lifting operation through the two screw drive gears.

[0016] As an optional embodiment, the screw assembly includes a screw shaft, a screw sleeve, and a turntable connecting rod. One end of the screw shaft is in transmission connection with the transmission assembly. The screw sleeve is threadedly sleeved on the screw shaft, and one end of the screw sleeve is hinged to one end of the turntable connecting rod. The other end of the turntable connecting rod is hinged to the turntable assembly. Therefore, the embodiment of the present application uses two screw shafts to synchronously drive the screw sleeve to slide up and down along the length of the screw shaft, and then uses the two screw sleeves to synchronously drive the turntable connecting rod to perform a lifting operation. Finally, the two turntable connecting rods synchronously drive the two turntable assemblies to rotate, ensuring that the two turntable assemblies can synchronously drive the two swing arms to swing.

[0017] As an optional embodiment, the turntable assembly includes a turntable seat, a turntable body, and a turntable crank. The turntable seat is mounted on the lifting mounting box.

One end of the turntable crank is connected to the turntable body, and the other end of the turntable crank is connected to the screw assembly via a turntable connecting rod. One end of the two rocker arms is respectively connected to the turntable bodies of the two turntable assemblies. Thus, in this embodiment of the application, the two screw assemblies synchronously drive the turntable cranks to rotate, and the two turntable bodies are then synchronously driven to rotate by the two turntable cranks, ensuring that the two turntable assemblies can synchronously drive the two rocker arms to swing.

[0018] As an optional embodiment, a turntable connecting block is provided at one end of the swing arm. The turntable connecting block is provided with a positioning boss. The turntable body is provided with a positioning slot that matches the positioning boss. The positioning boss of the turntable connecting block fits into the positioning slot, and the turntable connecting block is fixedly mounted on the turntable body.

[0019] As an optional embodiment, the lifting mechanism further includes a lifting mounting box, on which the transmission assembly, the screw assembly, and the turntable assembly are respectively mounted; the lifting mounting box is provided with a plurality of mounting holes.

The worm is coaxially arranged at the output end of the drive motor, the turbine is meshed with the worm, and the turbine is drivingly connected to the force transmission component. Therefore, the embodiment of the present application adopts a cooperative connection between the worm and the turbine, and the driving force of the drive motor can be synchronously transmitted to the force transmission component through the turbine.

[0021] As an optional embodiment, the force transmission assembly includes a connecting tube and two force transmission rods, each of which is threadedly connected to the ends of the connecting tube and drivenly connected to one end of the two lifting mechanisms; the driving mechanism is drivenly connected to one of the force transmission rods.

[0047] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings form part of the disclosure of the present invention and are primarily used to illustrate the embodiments and, in conjunction with the relevant description in the specification, to explain the operating principles of the embodiments. By referring to these drawings, those skilled in the art will be able to understand other possible implementations and the advantages of the present invention.

[0048] In order to facilitate users to hang and take off clothes, and to effectively improve users' comfort and satisfaction, most of the relevant wardrobes are equipped with electric lifting clothes rod equipment.

[0049] As shown in Figure 1, the electric lifting clothes rod device includes a U-shaped clothes rod 100 and a drive box 200 mounted on the side panel of the wardrobe. The middle section of the U-shaped clothes rod 100 is a clothes hanging rod 101 (for hanging clothes / hangers), and the two ends are swing rods 102. The bottom of the swing rod 102 is set on the drive box 200.

[0050] As shown in FIG2 , in conjunction with FIG1 , a drive box 200 houses a motor drive unit 201 and a spring buffer unit 202. The swing arm 102 is connected to the motor drive unit 201 via a turntable 203, which in turn is connected to a controller 205 via a power cord 204. Driven by the motor drive unit 201, the turntable 203 rotates. The rotation of the turntable 203 drives the swing arm 102 upward and downward, and accordingly, the clothes hanger 101. This allows the U-shaped clothes hanger 100 to automatically rise and fall.

[0051] In order to achieve a balanced support force between the two swing arms 102, two sets of drive motor devices 201 are usually provided. That is, the two swing arms 102 of the U-shaped clothes rail 100 are each connected to a drive box 200. In the case of two drive boxes 200, the drives of the two drive boxes 200 need to be synchronized. To this end, an encoder is usually also provided (the encoder is installed in the drive box 206 for synchronization adjustment).

[0052] However, the cost of two sets of drive motor devices 201 is high. The drive box 200 has many components and is slightly larger in size. The two sets of drive boxes 200 take up more space in the wardrobe, resulting in a smaller effective storage space in the wardrobe.

[0053] In addition, the installation of the drive box 200 requires opening a mounting hole 301 on the side panel of the wardrobe in advance and pre-burying a wire groove 302 on the side panel to ensure that the installation position of the two drive boxes 200 is accurate and to avoid position deviation and the undesirable phenomenon of jamming of the rotation of the two rocker arms 102. This makes the installation of the electric lifting clothes rod equipment more troublesome and is not conducive to promotion.

[0054] Based on this, an embodiment of the present application provides a lifting clothes rod device, which includes a drive mechanism 10, which is drivably connected to a force transmission assembly 20 and is used to drive the force transmission assembly 20 to rotate; the two ends of the force transmission assembly 20 are respectively connected to a lifting mechanism 30, so that the force transmission assembly 20 can synchronously drive the two lifting mechanisms 30 to operate, and then the two lifting mechanisms 30 synchronously drive the respective connected turntable assemblies 34 to rotate, thereby driving the two rocker rods 41 of the clothes rod assembly 40 to rotate synchronously, thereby achieving the lifting and rotation of the clothes hanging rod 42. It can be seen that the lifting clothes rod device provided in the embodiment of the present application can achieve the lifting and rotation of the clothes rod assembly 40 through a single drive mechanism 10. Compared with the related art, it not only effectively reduces the cost of the equipment, but also reduces the space occupied by the drive mechanism 10. In addition, the lifting clothes rod device provided in the embodiment of the present application uses the force transmission component 20 as a transmission component between the driving mechanism 10 and the two lifting mechanisms 30. The torque can be synchronously transmitted to the two lifting mechanisms 30 through the force transmission component 20, and the two lifting mechanisms 30 can be driven to operate synchronously. In this way, there is no need to adjust through the encoder, and it can also ensure that the two lifting mechanisms 30 can synchronously drive the clothes rod assembly 40 to lift and rotate, and make the rotation of the clothes rod assembly 40 smooth.

[0055] 3 , 4 and 18 , this embodiment provides a clothes rod lifting device, which includes a driving mechanism 10 , a force transmission assembly 20 , a lifting mechanism 30 , a turntable assembly 34 , a turntable connecting rod 333 , and a clothes rod assembly 40 .

[0056] The driving mechanism 10 is drivingly connected to the force transmission assembly 20, and the two ends of the force transmission assembly 20 are respectively connected to the lifting mechanism 30, each lifting mechanism 30 is connected to a turntable assembly 34, and the turntable assembly 34 is rotatably connected to the lifting mechanism 30 through a turntable connecting rod 333; the clothes rod assembly 40 includes a clothes hanging rod 42 and a rocker rod 41, and the two ends of the clothes hanging rod 42 are respectively connected to the rocker rod 41, and the clothes hanging rod 42 is connected to the two turntable assemblies 34 through two rocker rods 41.

[0057] The force transmission assembly 20 and the two lifting mechanisms 30 can form an inverted U-shaped transmission structure. The lifting clothes rod device of the embodiment of the present application is connected to the force transmission assembly 20 by a driving mechanism 10, so that the driving mechanism 10 can drive the force transmission assembly 20 to operate. The lifting mechanisms 30 are respectively connected to the lifting mechanisms 30 at both ends of the force transmission assembly 20. In this way, when the driving mechanism 10 drives the force transmission rod 22 to rotate, the force transmission rod 22 is linked to the two lifting mechanisms 30 for operation. The operation of the lifting mechanisms 30 drives the turntable assembly 34 to rotate along its axis. During the rotation of the turntable assembly 34 along its axis, the rocker 41 is driven to rotate along the axis of the turntable assembly 34. The rotation of the two rocker 41 links the clothes hanging rod 42 to rise and fall. Therefore, compared with the related electric lifting clothes rod device, the lifting clothes rod device of the embodiment of the present application can achieve the function of driving the clothes hanging rod assembly 40 to rise and fall through a single driving mechanism 10, eliminating the need for two driving mechanisms 10 to drive the clothes hanging rod assembly 40 to rise and fall, effectively reducing the cost of the device and also reducing the space occupied by the driving mechanism 10. In addition, by using the force transmission component 20 as a transmission component between the driving mechanism 10 and the two lifting mechanisms 30, the torque can be synchronously transmitted to the two lifting mechanisms 30 through the force transmission component 20, and the two lifting mechanisms 30 can be driven to operate synchronously. In this way, there is no need to adjust through the encoder to ensure that the two lifting mechanisms 30 can synchronously drive the clothes rod assembly 40 to lift and rotate, and the clothes rod assembly 40 can rotate smoothly, effectively avoiding the undesirable phenomenon of the clothes rod assembly 40 being stuck in rotation.

[0058] As shown in Figures 7, 8, and 10, the drive mechanism 10 includes a drive mounting box 11 and a drive motor 12, a worm 13, and a turbine 14 disposed on the drive mounting box 11. The worm 13 is rigidly connected to the output shaft of the drive motor 12, and the turbine 14 is meshed with the worm 13. A first bearing seat for rotating the turbine 14 is provided on the drive mounting box 11, so that the turbine 14 can rotate reliably. The turbine 14 is drive-connected to the force transmission assembly 20, so that the driving force generated by the drive motor 12 can be transmitted to the force transmission assembly 20 via the worm 13 and the turbine 14.

[0059] In addition, a mounting hole is provided on the drive mounting box 11 of this embodiment so that the drive mechanism 10 of this embodiment can be installed on the wardrobe, and a wire hole is provided on the wardrobe so that the power cord of the drive motor 12 can pass through the wire hole without the need to re-grooved and buried the wires inside the wardrobe.

[0060] As shown in Figures 11, 12, and 13, the force transmission assembly 20 includes a connecting tube 21 and two force transmission rods 22. The two force transmission rods 22 are respectively threadedly connected to the ends of the connecting tube 21 and are drivingly connected to one end of the two lifting mechanisms 30. The driving mechanism 10 is drivingly connected to one of the force transmission rods 22. In addition, the force transmission assembly 20 also includes a U-shaped cover, one end of which can be mounted on the drive mounting box 11 and encloses the connecting tube 21 and the two force transmission rods 22, thereby preventing the connecting tube 21 and the two force transmission rods 22 from being directly exposed in the wardrobe.

[0061] As shown in Figures 7, 8, and 10, the turbine 14 of the drive mechanism 10 is drivingly connected to one of the force transmission rods 22. In one embodiment, a polygonal hole 15 is provided in the middle of the turbine 14, and the cross-sectional shapes of the two force transmission rods 22 are adapted to the shape of the polygonal hole 15, so that one of the force transmission rods 22 can be inserted into the polygonal hole 15 of the turbine 14. Furthermore, through the coaxial driving connection between the turbine 14 and the force transmission rod 22, the driving force generated by the drive motor 12 can be transmitted to the entire force transmission assembly 20. In other words, in this embodiment, the drive motor 12 can drive the worm 13 to rotate, and the worm 13 can then drive the turbine 14 and the force transmission assembly 20 to rotate in sequence.

[0062] It is easy to understand that the polygonal hole 15 in the middle of the turbine 14 can be, but not limited to, a triangle, a quadrilateral, a pentagon, a hexagon, etc. Correspondingly, the shape of the cross section of the force transmission rod 22 can be, but not limited to, a triangle, a quadrilateral, a pentagon, a hexagon, etc.

[0063] In addition, as shown in Figure 13, both ends of the connecting tube 21 are provided with external threads 24, and one end of the force transmission rod 22 is provided with a knob 23, and the interior of the knob 23 is provided with an internal thread 25. The two force transmission rods 22 are respectively threadedly connected to the external threads 24 at both ends of the connecting tube 21 via their respective knobs 23. As a result, the force transmission assembly 20 of this embodiment adopts a variable length, and the overall length of the force transmission assembly 20 can be flexibly adjusted according to the width of the wardrobe, so that the lifting clothes rod device of this embodiment of the application can be used for wardrobes of different sizes, effectively improving the applicability of this application.

[0064] As shown in Figures 7 and 14, the lifting mechanism 30 includes a transmission assembly 32, a screw assembly 33, and a turntable assembly 34. The force transmission assembly 20 is drivingly connected to the transmission assemblies 32 of the two lifting mechanisms 30, the screw assembly 33 is drivingly connected to the transmission assembly 32, and the turntable assembly 34 is hinged to the screw assembly 33. One end of the two rocker arms 41 is respectively connected to the turntable assemblies 34 of the two lifting mechanisms 30. Thus, in the embodiment of the present application, the force transmission assembly 20 synchronously transmits torque to the two transmission assemblies 32, and the two transmission assemblies 32 synchronously drive the screw assembly 33 to perform lifting operations, so that the two screw assembly assemblies 33 synchronously drive the turntable assembly 34 to rotate, ensuring that the two turntable assemblies 34 can synchronously drive the two rocker arms 41 to swing.

[0065] As shown in Figure 14, the lifting mechanism 30 also includes a lifting mounting box 31, which is used to mount a transmission assembly 32, a screw assembly 33, and a turntable assembly 34. To facilitate mounting the lifting mechanism 30 on the side wall of the wardrobe, the side wall of the lifting mounting box 31 may be provided with a flange, and the flange may be provided with a mounting hole. In this way, the entire lifting mounting box 31 can be fixed to the side wall of the wardrobe by screws passing through the mounting holes.

[0066] As shown in Figure 9, the transmission assembly 32 includes a gear box 321, a transmission gear 322 and a screw drive gear 323. The gear box 321 is fixed to the upper end of the lifting installation box 31. The transmission gear 322 and the screw drive gear 323 are rotatably arranged in the gear box 321. The transmission gear 322 is meshed with the screw drive gear 323, and the screw drive gear 323 is driven and connected to the screw assembly 33. The two ends of the force transmission assembly 20 are respectively driven and connected to the transmission gears 322 of the two transmission assemblies 32. Therefore, the embodiment of the present application is driven and connected to the two transmission gears 322 at the two ends of the force transmission assembly 20, so that the force transmission assembly 20 can synchronously transmit torque to the two transmission gears 322, and then drive the screw drive gear 323 to rotate through the two transmission gears 322, and synchronously drive the screw assembly 33 to perform lifting operations through the two screw drive gears 323.

[0067] Among them, the gear box 321 is respectively provided with a second bearing seat and a third bearing seat, and the transmission gear 322 and the screw driving gear 323 are respectively rotatably arranged on the second bearing seat and the third bearing seat, and the axis of the transmission gear 322 is parallel to the length direction of the force transmission component 20, and the axis of the screw driving gear 323 is perpendicular to the axis of the transmission gear 322, so that the torque on the force transmission rod 22 can be transmitted to the screw driving gear 323 through the transmission gear 322, and the screw driving gear 323 drives the screw assembly 33 to perform lifting operations.

[0068] As shown in Figures 6 and 14, the screw assembly 33 includes a screw shaft 331 and a screw sleeve 332, wherein one end of the screw shaft 331 is coaxially fixedly connected to the screw drive gear 323 of the transmission assembly 32, the screw sleeve 332 is threadedly sleeved on the screw shaft 331, and the end of the screw sleeve 332 away from the screw drive gear 323 is hinged to one end of the turntable connecting rod 333, and the other end of the turntable connecting rod 333 is hinged to the turntable assembly 34. Therefore, in the embodiment of the present application, the two screw shafts 331 synchronously drive the screw sleeve 332 to slide up and down along the length direction of the screw shaft 331, and then the two screw sleeves 332 synchronously drive the turntable connecting rod 333 to perform a lifting operation, and finally the two turntable assemblies 34 are synchronously driven to rotate by the two turntable connecting rods 333, ensuring that the two turntable assemblies 34 can synchronously drive the two swing arms 41 to swing.

[0069] As shown in FIG14 , to ensure that the screw sleeve 332 can slide more smoothly along the screw shaft 331, an upper guide block 35 and a lower guide block 36 are spaced apart within the interior of the lift mounting box 31. The screw sleeve 332 is slidably disposed within the upper guide block 35 and the lower guide block 36. As the screw sleeve 332 slides up and down, the upper guide block 35 and the lower guide block 36 act as position limiting guides for the movement of the screw sleeve 332, thereby ensuring smoother and more stable sliding of the screw sleeve 332. Furthermore, a connecting rod guide groove 37 is provided within the lift mounting box 31, and the turntable connecting rod 333 is disposed within the connecting rod guide groove 37. Thus, the connecting rod guide groove 37 acts as a position limiting guide for the rotation of the turntable connecting rod 333, preventing the turntable connecting rod 333 from tilting during movement. The upper and lower ends of the turntable connecting rod 333 of this embodiment are hinged to the screw sleeve 332 and the turntable assembly 34, respectively, via pins.

[0070] As shown in Figures 14 and 15 , the turntable assembly 34 includes a turntable seat 341, a turntable body 342, and a turntable crank 343. The turntable seat 341 is fixed to the lift mounting box 31. A turntable sleeve 344 is provided on the turntable seat 341. The turntable body 342 is rotatably sleeved on the turntable sleeve 344. One end of the turntable crank 343 is connected to the turntable body 342, and the other end of the turntable crank 343 is hinged to the screw assembly 33 via a turntable connecting rod 333. One end of the two rocker arms 41 is respectively connected to the turntable bodies 342 of the two turntable assemblies 34. In this way, the embodiment of the present application drives the turntable connecting rod 333 to move by sliding the two screw rod assemblies 33 up and down, and synchronously drives the turntable crank 343 to rotate, and then synchronously drives the two turntable bodies 342 to rotate through the two turntable cranks 343, and the rocker arm 41 is also fixedly installed on the turntable body 342 and installed at a fixed angle with the turntable crank 343. The two form a lever structure. When the turntable crank 343 moves downward, the rocker arm 41 moves upward, ensuring that the two turntable assemblies 34 can synchronously drive the two rocker arms 41 to swing.

[0071] One end of the turntable crank 343 is hinged to one end of the turntable connecting rod 333 via a pin, and the other end of the turntable crank 343 is fixedly connected to the turntable body 342. Furthermore, a turntable connecting block 43 is provided at one end of the rocker arm 41. A positioning boss 44 is provided on the turntable connecting block 43, and a positioning slot 345 is provided on the turntable body 342 to match the positioning boss 44. The positioning boss 44 of the turntable connecting block fits into the positioning slot 345, and the turntable connecting block 43 is fixedly mounted on the turntable body 342. Thus, in this embodiment of the present application, the two rocker arms 41 are fixed to the turntable body 342 via the two turntable connecting blocks 43.

[0072] As shown in Figures 15 and 17, to facilitate the connection and fixation between the turntable connecting block 43 and the turntable body 342, the turntable body 342 may be provided with a plurality of threaded holes, and the turntable connecting block 43 may be provided with through holes at positions corresponding to the plurality of mounting holes. Thus, when the positioning bosses 44 of the turntable connecting block 43 are inserted into the positioning slots 345, screws are passed through the through holes of the turntable connecting block 43 and tightened into the threaded holes of the turntable body 342, thereby securing the turntable connecting block 43 to the turntable body 342. Furthermore, in this embodiment, the turntable body 342 may be provided with two positioning slots 345, and correspondingly, the turntable connecting block 43 may be provided with two positioning bosses 44. These two positioning bosses 44 ensure that the turntable connecting block 43 does not rotate relative to the turntable body 342, thereby making the connection between the turntable body 342 and the turntable connecting block 43 more compact and enabling the turntable body 342 to smoothly drive the rocker arm 41 to rotate.

[0073] As shown in FIG16 , the two swing arms 41 are provided with connecting sleeves 45 at opposite ends away from the turntable assembly 34. The connecting sleeves 45 can be fixed directly to the swing arms 41 or mounted thereon via fixing blocks. The ends of the clothes hanging rod 42 are respectively inserted into the two connecting sleeves 45, so that the clothes hanging rod 42 and the two swing arms 41 form a U-shaped clothes hanging rod assembly 40.

[0074] To facilitate the length adjustment of the force transmission assembly 20, the opposing portions of the two connecting sleeves 45 are cylindrical structures with one end open, and the openings of the two connecting sleeves 45 are arranged opposite each other. In this way, the ends of the clothes hanging rod 42 can be inserted into different positions within the two connecting sleeves 45. In addition, the connection between the clothes hanging rod 42 and the two connecting sleeves 45 in this embodiment can be connected by either an interference fit or a screw fixation method. A plurality of through holes are formed on the circumference of the connecting sleeves 45, and a threaded hole is formed on the circumference of one end of the clothes hanging rod 42. In this way, the clothes hanging rod 42 can be fixed to the connecting sleeves 45 by screws after the threaded holes of the clothes hanging rod 42 are aligned with the different through holes.

[0075] As shown in FIG. 18 to FIG. 20 , the process of the clothes hanging rod 42 descending and rotating from a high position to a low position during use of the clothes lifting rod device is shown.

[0076] As shown in Figure 18, at this time, the clothes hanging rod 42 is located at a high place, and the driving mechanism 10 drives the force transmission component 20 to operate, thereby driving the two screw shafts 331 to rotate, and causing the two screw sleeves 332 to slide up synchronously. During the sliding process, the two screw sleeves 332 drive the turntable connecting rod 333 to move upward, and simultaneously drive the turntable crank 343 to move upward, and then synchronously drive the two turntable bodies 342 to rotate through the two turntable cranks 343, and the rocker arm 41 is also fixedly installed on the turntable body 342. When the turntable crank 343 moves upward, the rocker arm 41 moves downward.

[0077] As shown in FIG. 19 , at this time, the swing rod 41 swings downward by a certain angle, and the clothes hanging rod 42 also descends and rotates accordingly.

[0078] As shown in FIG20 , the swing arm 41 has further swung downwards to a certain angle, and the clothes hanging rod 42 is at a lower position, making it easier for the user to hang or take clothes. When the user has finished hanging or taking clothes, the swing arm 41 is driven upwards by controlling the screw sleeve 332 to move downwards, thereby simultaneously driving the clothes hanging rod 42 to rise and rotate to a higher position.

[0079] Compared to related technologies, the lifting clothes rod device of the present embodiment utilizes a single drive mechanism 10 to drive the clothes rod assembly 40, resulting in better synchronization. This allows for simultaneous rotation of the two turntable assemblies 34 without the need for an encoder, resulting in smoother and more stable rotation of the two rocker arms 41 and lower costs. Furthermore, the drive mechanism 10 can be mounted directly on the top of the wardrobe, allowing wiring to be routed through openings in the wardrobe's top, eliminating the need for slots in the wardrobe's sidewalls for wiring and preventing damage to the wardrobe's overall structure. In addition, the force transmission component 20 adopts an adjustable length. During installation, the two lifting mechanisms 30 are first installed at the same height on both sides of the wardrobe, and then the two force transmission rods 22 are twisted relative to the connecting pipe 21 to adjust the overall length of the force transmission component 20 to adapt to the distance between the two lifting mechanisms 30. Then, the two force transmission rods 22 are respectively inserted into the transmission gears 322 of the two lifting mechanisms 30, and one of the force transmission rods 22 is simultaneously inserted into the turbine 14 of the driving mechanism 10; then the two rocker arms 41 are installed on the turntable assemblies 34 of the two lifting mechanisms 30, and finally, the clothes hanging rod 42 is fixed on the two connecting sleeves 45 and the total length of the clothes hanging rod 42 and the two connecting sleeves 45 is adapted to the length of the force transmission component 20, so that the lifting clothes rod device of the embodiment of the present application can be suitable for wardrobes of different sizes, effectively improving the applicability of the lifting clothes rod device of the embodiment of the present application.

[0080] In addition, an embodiment of the present application also provides a wardrobe, which includes the lifting clothes rod device described above.

[0081] As shown in Figure 21, wardrobe 400 is provided with a cabinet space for mounting a lifting rod device. Within the cabinet space, a drive mechanism 10, a force transmission assembly 20, and two lifting mechanisms 30 are mounted on the back panel of wardrobe 400. A turntable assembly 34 is mounted on the front lower end of the lifting mechanism 30. The lower end of a swing arm 41 is fixed to the turntable assembly 34, and the upper end of the swing arm 41 is connected to a clothes hanging rod 42. The drive mechanism 10 is connected to a controller 500 via a power cord. The controller 500 is used to control the operation of the drive mechanism 10. A power plug can be drawn from the controller 500 for plugging in. During use, the user controls the forward and reverse operation of the drive mechanism 10 via the controller 500 to drive the clothes hanging rod assembly 40 to raise and lower the rod assembly 40.
