[0021] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0022] refer to Figures 1 to 7, this application requests protection for a clothes drying rod controlled by a single motor, which is used to realize the movement control of the movable load 2 on the fixed rod 1. The clothes drying machine generally includes a main unit, a drying component controlled by the main unit, and a lifting frame C connecting the main unit and the drying component. The drying component is based on the fixed rod 1 and can be structurally expanded and adjusted. The movable load 2 on the fixed rod 1 includes but is not limited to a mounting component, a telescopic rod, a drying net, and a quilt drying rod. Among them, the mounting component is arranged on the fixed rod 1, and can control the separation or gathering between the mounting components; the telescopic rod is arranged inside the fixed rod 1, and can slide along the longitudinal direction of the fixed rod 1 to realize the expansion and storage of the telescopic rod, and the drying net can slide along the longitudinal direction of the fixed rod 1 to realize expansion and storage; the quilt drying rod is folded and stored on the outer periphery of the fixed rod 1, and can be hung under or on both sides of the fixed rod 1 after expansion.

[0023] The single-motor controlled drying rod of the present application includes a fixed rod 1, a movable load 2 and a power component 3. The movable load 2 includes at least a first load component 21 and a second load component 22 arranged on the fixed rod 1. The power component 3 includes a motor 31 provided with an output shaft 311 and a gear set 32 ​​linked to the motor 31. The first load component 21 and the second load component 22 are respectively controlled by the gear set 32.

[0024] In this embodiment, the first load component 21 includes a mounting component, which can be separated or gathered along the longitudinal direction of the fixed rod 1. The second load component 22 includes a telescopic rod, which is sleeved on the end of the fixed rod 1 and can slide relative to the fixed rod 1 to adjust the hanging length of the fixed rod 1.

[0025] In the prior art, the first load assembly 21 and the second load assembly 22 are respectively controlled by a synchronous belt 34 in conjunction with various stoppers or micro switches. One possible implementation method is to fix the components to be controlled to move on the synchronous belt 34 and move with the synchronous belt 34. The two ends of the synchronous belt 34 are respectively tensioned by rolling wheels. By controlling the rotation of the rolling wheel at one end, the moving speed and stroke of the synchronous belt 34 can be controlled.

[0026] For example, the mounting assembly includes multiple mounting members connected end to end, with the mounting members at each end respectively abutting against two stoppers moving in opposite directions. Driven by the corresponding synchronous belt 34, both the mounting members and the stoppers can translate in a predetermined direction. When the two stoppers approach each other along the longitudinal direction of the fixed rod 1, they push the mounting members together one by one. When the two stoppers move away from each other along the longitudinal direction of the fixed rod 1, they pull the mounting members apart one by one. The mounting members can separate or converge in two directions simultaneously.

[0027] The telescopic rod comprises two rods sleeved on either end of the fixed rod 1, each rod abutting against a stopper capable of opposite movement. Driven by the corresponding timing belt 34, the stopper can translate in a predetermined direction. When the two stoppers approach each other along the longitudinal direction of the fixed rod 1, the two rods are driven to converge and be stored within the fixed rod 1. When the two stoppers move away from each other along the longitudinal direction of the fixed rod 1, the two rods are driven to separate and be pushed out of the fixed rod 1. The telescopic rod can be extended or shortened in both directions simultaneously.

[0028] refer to Figure 2 The power assembly 3 of this embodiment includes a first transmission rod 326 for controlling the mount assembly and a second transmission rod 327 for controlling the telescopic rod. These first and second transmission rods 326, 327 serve as the synchronous drive mechanism for the aforementioned rolling wheels. Rolling wheels are provided at both ends of the first and second transmission rods 326, 327 for mounting a timing belt 34, enabling synchronous control of the movable load 2 on the two parallel fixed rods 1. Driven rods are also provided on opposite sides of the first and second transmission rods 326, 327, for tensioning the timing belt 34.

[0029] refer to Figures 3 to 7 The motor 31 in the present application is provided with at least one output shaft 311. Based on the output shaft 311, the gear set 32 ​​includes a first driven wheel 321 for controlling the mounting assembly linked with the motor 31, and a second driven wheel 322 for controlling the telescopic rod linked with the motor 31. Both the first driven wheel 321 and the second driven wheel 322 can be driven by the motor 31, so that the motor 31 can control the mounting assembly and the telescopic rod at the same time. In a possible embodiment, the output shaft 311 of the motor 31 is provided with a gear that can mesh or transmit with the first driven wheel 321. The first transmission wheel 3241 is further provided with a second transmission wheel 3251 that can engage or transmit with the second driven wheel 322, and the first transmission wheel 3241 and the second transmission wheel 3251 are close to each other, so that a gear box 33 is set between the motor 31 and the first transmission rod 326 and the second transmission rod 327, so as to fix the spatial matching position among the first driven wheel 321, the second driven wheel 322, the first transmission wheel 3241, the second transmission wheel 3251, the first transmission rod 326 and the second transmission rod 327, thereby improving the stability of the transmission.

[0030] In this embodiment, the mounting assembly moves on the upper surface of the fixed rod 1, the telescopic rod moves inside the fixed rod 1, and the corresponding first driven rod and the second driven rod are arranged vertically and parallel to each other. The gear box 33 is provided with corresponding through holes, such as Figure 6 and Figure 7As shown, the gear box 33 has a first through hole 3311 passing horizontally therethrough for fixing the first transmission rod 326, and the first transmission rod 326 is nested on the pivot 3211 of the first driven wheel 321, so that the first driven wheel 321 and the first transmission rod 326 rotate synchronously; the gear box 33 has a second through hole 3312 passing horizontally therethrough for fixing the second transmission rod 327, and the second transmission rod 327 is nested on the pivot 3221 of the second driven wheel 322, so that the second driven wheel 322 and the second transmission rod 327 rotate synchronously.

[0031] The first transmission rod 326 and the second transmission rod 327 control different loads, and the required rotational speeds of the two may be different. When the required rotational speeds of the two are different, the pitch circle sizes of the first driven wheel 321 and the second driven wheel 322 may be different, and the gear ratios of the two may also be different. Therefore, at least one adjustment wheel 323 can be set between the first driven wheel 321 and the second driven wheel 322 and the transmission wheels (first transmission wheel 3241 and second transmission wheel 3251) of the motor 31. In this embodiment, the pitch circle of the first driven wheel 321 is larger than the pitch circle of the second driven wheel 322, thereby controlling the rotational speed of the first transmission rod 326 to be lower than the rotational speed of the second transmission rod 327. The first driven wheel 321 can directly mesh with the first transmission wheel 3241 to transmit the torque of the motor 31. The second driven wheel 322 cannot directly mesh with the second transmission wheel 3251 due to spatial constraints, and the output rotational speed of direct meshing is not compatible. Therefore, an idler gear serving as an adjustment wheel 323 is provided between the second driven wheel 322 and the second transmission wheel 3251 to transmit the torque of the motor 31 and adjust the output torque during the transmission process. In other embodiments, the transmission parameters of the first driven wheel 321, the second driven wheel 322, and the motor 31 can be adaptively adjusted, and the usage of the adjustment wheel 323 can also be adaptively adjusted.

[0032] Furthermore, the first transmission rod 326 and the second transmission rod 327 control different loads, and the operating times of the two movable loads 2 may be asynchronous. To meet the requirement of "asynchronous operation," at least one clutch is provided on the output shaft 311 of the motor 31 to control the asynchronous operation of the two loads. Optionally, a first clutch 324 is provided, which is linked to the first driven wheel 321, wherein the aforementioned first transmission wheel 3241 is subordinate to the first clutch 324; and / or a second clutch 325 is provided, which is linked to the second driven wheel 322, wherein the aforementioned second transmission wheel 3251 is subordinate to the second clutch 325. When the clutch is energized, the transmission wheels (the first transmission wheel 3241 and / or the second transmission wheel 3251) can rotate synchronously with the output shaft 311 of the motor 31, further driving the corresponding transmission rods (the first transmission rod 326 and / or the second transmission rod 327) to rotate via the gear set 32, thereby controlling the corresponding movable load 2. When the clutch is de-energized, the transmission wheels cannot rotate synchronously with the output shaft 311 of the motor 31, and the corresponding movable load 2 cannot be controlled by the motor 31. Therefore, by controlling the conduction condition of the clutch, one motor 31 can be used to realize selective control or synchronous control of the two movable loads 2 .

[0033] To facilitate assembly, the present application assembles the first clutch 324, the first driven wheel 321, the second driven wheel 322, and the idler wheel in the gear box 33 according to a preset spatial position relationship, and reserves an assembly hole 3313 connected to the first clutch 324 to facilitate the connection of the output shaft 311 of the motor 31 with the first clutch 324; the assembly hole 3313 horizontally passes through the gear box 33, and is parallel to the aforementioned first through hole 3311 and second through hole 3312, so that the output shaft 311 of the motor 31, the first transmission rod 326 and the second transmission rod 327 are parallel to each other in space (not necessarily coplanar); the second clutch 325 and the motor 31 are pre-installed through the motor bracket 35, and the motor 31 assembled with the second clutch 325 can be reconnected with the first clutch 324 through the assembly hole 3313, and the second transmission wheel 3251 of the second clutch 325 can be positioned inside the gear box 33 to facilitate driving the second transmission rod 327.

[0034] refer to Figure 6 and 7 The gear box 33 includes a first box body 331 and a second box body 332. The first box body 331 is used to accommodate the gear set 32, and the accommodated gear set 32 ​​includes a first transmission wheel 3241, a first driven wheel 321, a second transmission wheel 3251, a second driven wheel 322 and an adjusting wheel 323, wherein the first driven wheel 321, the second driven wheel 322 and the adjusting wheel 323 are fixedly installed in the first box body 331, the second driven wheel 322 is meshed with the adjusting wheel 323, and the first driven wheel 321 and the second driven wheel 322 are parallel to each other and not coplanar (such as Figure 4 and 5 (as shown), and through-holes (first through-hole 3311 and second through-hole 3312) are defined at the pivots of the first transmission wheel 3241 and the second transmission wheel 3251, respectively. To accommodate the external assembly environment of the gearbox 33, the first housing 331 can be configured as a rectangular parallelepiped. The side of the first housing 331 facing the motor 31 is defined as the front, and the side facing away from the motor 31 is defined as the back. The second box body 332 extends from the back of the first box body 331. The inner cavities of the first box body 331 and the second box body 332 are connected. The second box body 332 is used to accommodate the first clutch 324 including the first transmission wheel 3241. The first clutch 324 extends the first transmission wheel 3241 into the first box body 331 and engages with the first transmission wheel 3241. On the front of the first box body 331, an assembly hole 3313 is provided for the second clutch 325 to extend into the second transmission wheel 3251, and the first transmission wheel 3241 and the second transmission wheel 3251 are arranged coaxially so that the output shaft 311 of the motor 31 can pass through the assembly hole 3313 through the pivot of the first transmission wheel 3241 (such as Figure 4 shown).

[0035] Adapting to the transmission structure of the mounting assembly and telescopic rod, the power assembly 3 of the present application can be placed in a bracket B connected orthogonally to the fixed rod 1. The ends of the first transmission rod 326 and the second transmission rod 327 extend to the fixed rod 1 respectively, and are used to drive the timing belt 34 stored inside the fixed rod 1. The bracket B of the prior art is usually placed at both ends of the fixed rod 1, connected orthogonally to the fixed rod 1 to form a rectangular drying frame structure, and the bracket B is provided with a lifting frame C for adjusting the distance between the fixed rod 1 and the main unit. This embodiment can provide conditions for storing the power assembly 3 by expanding the storage space of the bracket B.

[0036] In other possible implementations, a motor 31 with dual or multiple output shafts 311 can be used in conjunction with another gear set 32 ​​to control other movable loads 2. Alternatively, an additional clutch and corresponding gear set 32 ​​can be provided on the output shaft 311 of the original motor 31 to control an additional movable load 2.

[0037] The gear set 32 ​​of the present application utilizes spur gears for transmission. Spur gears are simple in design and easy to manufacture, have strong load-bearing capacity, stable transmission ratios, and are durable. Furthermore, by varying the spur gear tooth ratio, various transmission ratios can be achieved to meet the requirements of different movable loads 2. Furthermore, the gear set 32 ​​can also vary the transmission direction by employing different transmission components other than spur gears, adapting to the control of movable loads 2 with different spatial layouts. Other transmission components, such as worm gear transmission components, belt transmission components, or chain transmission components, can also be employed in the gear set 32 ​​as needed.

[0038] In summary, the present application provides a single-motor controlled clothes-drying rod, comprising: a fixed rod; a movable load, comprising at least a first load assembly and a second load assembly disposed on the fixed rod; and a power assembly, comprising a motor having an output shaft and a gear set linked to the motor, wherein the relative positions of the first load assembly and the second load assembly on the fixed rod are controlled by the gear set. The single-motor controlled clothes-drying rod of the present application, using a motor having an output shaft and a gear set linked thereto, can simultaneously control at least two movable loads, effectively reducing the number of motors used and contributing to saving manufacturing costs.
