Technical Field

[0001] This application relates to the field of clothes drying rack technology, and more specifically, to an electric clothes drying rack and its power component controlled by a single motor. Background Technology

[0002] Existing electric clothes drying racks typically have movable hanging parts to facilitate the gathering or detaching of clothes on the drying rod, and also have telescopic rods to selectively expand the drying area. Both the hanging parts and the telescopic rods are mounted on a fixed rod and can be positioned relative to the fixed rod. However, the usage scenarios for these two components are different, and the range of movement that needs to be controlled is also different. Current technology usually uses two motors to independently control these two components. This control method has high requirements for the synchronization control of the motors, and the use of multiple motors also increases energy consumption. Utility Model Content

[0006] Alternatively, the power assembly may further include a first transmission rod linked to the first driven wheel and a second transmission rod linked to the second driven wheel.

[0007] Alternatively, the first transmission rod is nested on the pivot of the first driven wheel and rotates synchronously with the first driven wheel; the second transmission rod is nested on the pivot of the second driven wheel and rotates synchronously with the second driven wheel.

[0008] Alternatively, the power assembly is disposed within a bracket orthogonally connected to the fixed rod, with the ends of the first and second transmission rods extending to the fixed rod for linkage with a synchronous belt housed within the fixed rod.

[0009] Alternatively, the output shaft of the motor, the first transmission rod, and the second transmission rod are parallel to each other; the first transmission rod and the second transmission rod rotate at different speeds.

[0010] Furthermore, the gear set also includes a first clutch and / or a second clutch that are coupled to the first driven wheel and coupled to the second driven wheel, respectively, disposed on the output shaft of the motor; the drive wheels of the first clutch and the second clutch are opposite to each other.

[0012] Alternatively, the gear set may be at least partially assembled in a gearbox.

[0013] Secondly, this application also provides an electric clothes drying rack, including a main unit and a drying assembly controlled by the main unit, wherein the drying assembly includes a power assembly controlled by a single motor as described above.

[0014] Alternatively, the power assembly is disposed within the bracket of the drying assembly, and the two ends of the first and second transmission rods extend to the fixing rod of the drying assembly, respectively, for linkage with the synchronous belt housed within the fixing rod.

[0031] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0032] refer to Figures 1-7 This application claims protection for a single-motor controlled power assembly for controlling the movement of a movable load 2 on a fixed rod 1 of a clothes drying rack. The clothes drying rack typically includes a main unit, a drying assembly controlled by the main unit, and a lifting frame C connecting the main unit and the drying assembly. The drying assembly 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 hanging assembly, a telescopic rod, a drying net, and a quilt drying rod. The hanging assembly is mounted on the fixed rod 1 and can control the separation or convergence of the hanging assemblies; the telescopic rod is sleeved inside the fixed rod 1 and can slide along the longitudinal direction of the fixed rod 1 to achieve the unfolding and retraction of the telescopic rod; the drying net can slide along the longitudinal direction of the fixed rod 1 to achieve unfolding and retraction; the quilt drying rod is folded and stored around the outer periphery of the fixed rod 1 and can be suspended below or to the sides of the fixed rod 1 after unfolding.

[0033] The drying rack in this embodiment includes a fixed rod 1, a movable load 2, and a power assembly 3. The movable load 2 includes at least a first load assembly 21 and a second load assembly 22 disposed on the fixed rod 1. The power assembly 3 includes a motor 31 with an output shaft 311 and a gear set 32 ​​that is linked with the motor 31. The first load assembly 21 and the second load assembly 22 are controlled by the gear set 32 ​​respectively.

[0034] In this embodiment, the first load component 21 includes a hanging component that can separate or converge along the longitudinal direction of the fixed rod 1. The second load component 22 includes a telescopic rod that 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.

[0035] In the prior art, the first load component 21 and the second load component 22 are controlled by a timing belt 34 in conjunction with various stop components or micro switches. One possible implementation is to fix the component to be moved on the timing belt 34 and move with the timing belt 34. Both ends of the timing belt 34 are tensioned by rollers. By controlling the rotation of the roller at one end, the moving speed and stroke of the timing belt 34 can be controlled.

[0036] For example, the mounting assembly includes multiple mounting pieces connected end-to-end, with each mounting piece at one end abutting against two opposing stop pieces. Both the mounting pieces and the stop pieces can translate in a predetermined direction under the drive of the corresponding synchronous belt 34. When the two stop pieces approach each other along the longitudinal direction of the fixed rod 1, they push the mounting pieces together one by one; when the two stop pieces move away from each other along the longitudinal direction of the fixed rod 1, they pull the mounting pieces apart one by one. The mounting pieces can separate or converge in both directions simultaneously.

[0037] The telescopic rod includes two branch rods sleeved at both ends of a fixed rod 1. Each branch rod abuts against a stop member capable of moving in opposite directions. The stop members can translate in a predetermined direction under the drive of the corresponding synchronous belt 34. When the two stop members approach each other along the longitudinal direction of the fixed rod 1, they drive the two branch rods to converge and be housed inside the fixed rod 1. When the two stop members move away from each other along the longitudinal direction of the fixed rod 1, they drive the two branch rods to separate and be pushed out of the fixed rod 1. The telescopic rod can extend or retract simultaneously in both directions.

[0038] refer to Figure 2 The power assembly 3 in this embodiment includes a first transmission rod 326 for controlling the mounting assembly and a second transmission rod 327 for controlling the telescopic rod. The first transmission rod 326 and the second transmission rod 327 are the aforementioned synchronous drive structure of the rolling wheels. The two ends of the first transmission rod 326 and the second transmission rod 327 are respectively set as rolling wheels for mounting the synchronous belt 34, so as to synchronously control the movable load 2 on the two parallel fixed rods 1. On the opposite side of the first transmission rod 326 and the second transmission rod 327, driven rods are also respectively provided for tensioning the synchronous belt 34.

[0039] refer to Figures 3-7 In this application, the motor 31 has at least one output shaft 311. Based on this output shaft 311, the gear set 32 ​​includes a first driven wheel 321 linked to the motor 31 for controlling the mounting assembly, and a second driven wheel 322 linked to the motor 31 for controlling the telescopic rod. 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 simultaneously control the mounting assembly and the telescopic rod. In a possible implementation, the output shaft 311 of the motor 31 is provided with a mechanism that can mesh or drive the first driven wheel 321. The first drive wheel 3241 is also provided with a second drive wheel 3251 that can mesh or drive with the second driven wheel 322. The first drive wheel 3241 and the second drive wheel 3251 are close to each other so as to facilitate the arrangement of a gearbox 33 between the motor 31 and the first drive rod 326 and the second drive rod 327, so as to fix the spatial matching position between the first driven wheel 321, the second driven wheel 322, the first drive wheel 3241, the second drive wheel 3251, the first drive rod 326 and the second drive rod 327, thereby improving the stability of the transmission.

[0040] In this embodiment, the mounting assembly moves on the upper surface of the fixed rod 1, and the telescopic rod moves inside the fixed rod 1. The corresponding first driven rod and second driven rod are arranged vertically in parallel, adapting to the arrangement of the first driven rod and second driven rod. The gearbox 33 is provided with corresponding through holes, such as... Figure 6 and Figure 7As shown, the gearbox 33 has a horizontal through hole 3311 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 gearbox 33 has a horizontal through hole 3312 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.

[0041] The loads controlled by the first transmission rod 326 and the second transmission rod 327 are different, and the required speeds of the two may be different. When the required 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 adjusting wheel 323 can be provided 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 that of the second driven wheel 322, thereby controlling the rotational speed of the first transmission rod 326 to be less than that 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. Due to spatial constraints, the second driven wheel 322 cannot directly mesh with the second transmission wheel 3251, and the output speed from direct meshing would be incompatible. Therefore, an idler gear, which serves as an adjusting 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 transmission. 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 adjusting wheel 323 can also be adaptively adjusted.

[0042] Furthermore, since the first transmission rod 326 and the second transmission rod 327 control different loads, the working times of the two movable loads 2 may be asynchronous. To accommodate the requirement of "asynchrony," at least one clutch is provided on the output shaft 311 of the motor 31 to control the asynchrony of the two loads. Optionally, a first clutch 324 linked to the first driven wheel 321 is provided, wherein the aforementioned first transmission wheel 3241 is subordinate to the first clutch 324; and / or a second clutch 325 linked to the second driven wheel 322 is provided, wherein the aforementioned second transmission wheel 3251 is subordinate to the second clutch 325. When the clutch is energized, the transmission wheels (first transmission wheel 3241 and / or second transmission wheel 3251) can rotate synchronously with the output shaft 311 of the motor 31, further driving the corresponding transmission rods (first transmission rod 326 and / or second transmission rod 327) to rotate through 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 engagement of the clutch, one motor 31 can be used to achieve selective or synchronous control of the two movable loads 2.

[0043] For ease of assembly, this application assembles the first clutch 324, the first driven wheel 321, the second driven wheel 322, and the idler wheel in the gearbox 33 according to a preset spatial relationship, and reserves an assembly hole 3313 communicating with the first clutch 324 so that the output shaft 311 of the motor 31 can be connected to the first clutch 324. The assembly hole 3313 horizontally penetrates the gearbox 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 is pre-installed with the motor 31 through the motor bracket 35. The motor 31 with the second clutch 325 assembled can be reconnected to the first clutch 324 through the assembly hole 3313. The second transmission wheel 3251 of the second clutch 325 can be positioned inside the gearbox 33 so as to drive the second transmission rod 327.

[0044] refer to Figure 6 and 7 The gearbox 33 includes a first housing 331 and a second housing 332. The first housing 331 houses the gear set 32, which includes a first drive gear 3241, a first driven gear 321, a second drive gear 3251, a second driven gear 322, and an adjusting gear 323. The first driven gear 321, the second driven gear 322, and the adjusting gear 323 are fixedly installed inside the first housing 331. The second driven gear 322 meshes with the adjusting gear 323. The first driven gear 321 and the second driven gear 322 are parallel to each other and not coplanar (e.g., ...). Figure 4 and 5 As shown), through holes are made at the pivot of the first transmission wheel 3241 and the pivot of the second transmission wheel 3251, respectively, which are the first through hole 3311 and the second through hole 3312. To adapt to the assembly environment outside the gearbox 33, the first box 331 can be configured with a rectangular outer contour. The side of the first box 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 housing 332 extends from the back of the first housing 331. The inner cavities of the first housing 331 and the second housing 332 are connected. The second housing 332 is used to accommodate the first clutch 324, which includes the first drive wheel 3241. The first clutch 324 extends the first drive wheel 3241 into the first housing 331 and engages with it. On the front of the first housing 331, a mounting hole 3313 is provided for the second clutch 325 to extend into the second drive wheel 3251, and the first drive wheel 3241 and the second drive wheel 3251 are arranged coaxially so that the output shaft 311 of the motor 31 can pass through the pivot of the first drive wheel 3241 (e.g., through the mounting hole 3313) from the mounting hole 3313. Figure 4 (As shown).

[0045] Adapted to the transmission structure of the mounting assembly and telescopic rod, the power assembly 3 of this application can be housed within the bracket B orthogonally connected 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, for linkage with the synchronous belt 34 housed inside the fixed rod 1. In the prior art, the bracket B is typically located at both ends of the fixed rod 1, orthogonally connected to it to form a rectangular drying frame structure, and the bracket B is equipped with a lifting frame C for adjusting the distance between the fixed rod 1 and the main unit. This embodiment can expand the storage space of the bracket B to provide conditions for the storage of the power assembly 3.

[0046] In other possible implementations, a motor 31 with dual or multiple output shafts 311 can be used, along with an additional gear set 32, to control other movable loads 2. Alternatively, an additional clutch and a corresponding gear set 32 ​​can be installed on the original motor 31 output shaft 311 to control an additional movable load 2.

[0047] The gear set 32 ​​of this application uses spur gears for transmission. Spur gears are simple in design, easy to manufacture, have strong load-bearing capacity, stable transmission ratio, and are durable. Furthermore, various transmission ratios can be achieved by changing the number of teeth on the spur gears to meet the usage requirements of different movable loads 2. Moreover, the gear set 32 ​​can also change the transmission direction by using different transmission components other than spur gears to adapt to the control of movable loads 2 with different spatial layouts. Other transmission components can also be used in the gear set 32 ​​according to actual needs, such as introducing worm gear transmission components, belt transmission components, or chain transmission components.

[0048] In summary, this application provides a single-motor controlled power assembly, which includes a motor with an output shaft and a gear set linked to the motor. The gear set controls the movement positions of the first load assembly and the second load assembly, respectively. This single-motor controlled power assembly, employing a motor with an output shaft and a gear set linked to it, can simultaneously control at least two movable loads, effectively reducing the number of motors used and saving manufacturing costs.
