DETAILED DESCRIPTION

[0035] In order to more clearly understand the above-mentioned purposes, features and advantages of the embodiments of the present invention, the scheme of the embodiments of the present invention will be further described below. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0036] In the following description, many specific details are set forth to facilitate a full understanding of the embodiments of the utility model, but the embodiments of the utility model can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the utility model, rather than all of the embodiments.

[0037] Reference Figures 1 to 5 As shown, this embodiment provides a driving device for a clothes drying rack (hereinafter referred to as the driving device). The driving device 10 and the clothes drying rack can form a clothes drying system for users to dry clothes, etc.

[0038] The clothes drying rack may include a main unit 20 and a clothes drying rod 30. The driving device 10 may be specifically arranged on the main unit 20. The main unit 20 is usually connected to the top wall of the balcony space such as the ceiling. For example, the main unit 20 corresponds to Figure 1 One side of the XOY can be connected to the ceiling.

[0039] The driving device 10 includes a driving structure 2 and a traction member 3. The driving structure 2 is connected to the clothes drying rack, and a rotatable wire winding wheel 4 is connected to the driving structure 2. One end of the traction member 3 is connected to the wire winding wheel 4, and the other end of the traction member 3 is used to connect to the clothes drying rod 30. When the clothes drying system is installed in place at a position such as a ceiling, the wire winding wheel 4 can be rotated around its own axis. The axis of the wire winding wheel 4 is Figures 1 to 4 In the Z direction.

[0040] The traction member 3 may be, for example, a traction rope, such as a steel wire rope, a hemp rope, etc.; or the traction member 3 may also be a chain, etc.

[0041] Specifically, the driving structure 2 is used to drive the winding wheel 4 to rotate so that the traction member 3 is wound on the winding wheel 4, and the outer contour circumference of the winding wheel 4 is not less than 1 / 5 times the maximum lifting stroke of the clothes drying rod 30. The outer contour circumference of the winding wheel 4 specifically refers to the circumference of the outer contour on the radial plane of the winding wheel 4. The radial plane of the winding wheel 4 is specifically Figures 1 to 4 The XOY plane is shown.

[0042] Specifically, when the outer contour of the radial plane of the winding wheel 4 is a circle, the outer contour circumference of the winding wheel 4 specifically refers to the circumference of the circle. Figures 1 to 4 The maximum distance that the clothes-drying rod 30 can be lifted and moved under the action of the driving structure 2 and the traction member 3 is the distance between the highest position and the lowest position of the clothes-drying rod 30 when in use.

[0043] For example, the maximum lifting stroke of the clothes-drying rod 30 can be 120 cm, and 1 / 5 times of the maximum lifting stroke of the clothes-drying rod 30 is 24 cm, that is, the outer contour circumference of the winding wheel 4 is not less than 24 cm, that is, the winding wheel 4 can rotate at most five times to realize the clothes-drying rod 30 in Figures 1 to 4 The Z in the figure moves upward by 120 cm, which reduces the length of the portion of the winding wheel 4 used for winding the traction member 3 in the axial direction to a certain extent, thereby facilitating the reduction of the axial dimension of the winding wheel 4, so that the winding wheel 4 can be formed into a disc-shaped structure with a radial dimension greater than an axial dimension, which is beneficial to reducing the thickness of the entire driving device 10, and saves the space occupied by the driving device 10 to a certain extent, meets the structural space requirements, and enables the clothes drying rack to be better implanted in environments such as balconies.

[0044] Reference Figure 1As shown, the driving device 10 can be connected to the host 20. The host 20 can have a receiving cavity, for example. The driving device 10 is located in the receiving cavity, and a through hole can be opened on the cavity wall of the receiving cavity for the other end of the traction member 3 to extend out.

[0045] Illustratively, the driving structure 2 can be controlled to start working, so that the winding wheel 4 rotates under the action of the driving structure 2, and the traction member 3 drives the clothes-drying rod 30 to move downward in a direction away from the ceiling, so that the user can hang clothes on the clothes-drying rod 30; when the clothes are hung, the driving structure 2 continues to be controlled to work, and the winding wheel 4 is driven to rotate in the opposite direction, so that the traction member 3 drives the clothes-drying rod 30 to move upward in a direction close to the ceiling, so as to realize the drying of clothes.

[0046] When implementing it, refer to Figure 1 As shown, the clothes drying rack may further include a hanging mechanism 40, wherein the hanging mechanism 40 may be arranged along the lifting direction of the clothes drying rod 30 (specifically, Figures 1 to 4 A telescopic structure (such as a scissors rack, a telescopic rod, etc.) that reciprocates and telescopes in the Z direction (in the Z direction), and the suspension mechanism 40 can be connected between the main unit 20 and the clothes-drying rod 30. When the clothes-drying rod 30 is raised or lowered, the suspension mechanism 40 can be extended or retracted at least driven by the clothes-drying rod 30, thereby improving the stability of the lifting and lowering of the clothes-drying rod 30.

[0047] The driving device for the clothes drying rack provided in the present embodiment makes the outer circumference of the winding wheel member 4 not less than 1 / 5 times the maximum lifting stroke of the clothes drying rod member 30, thereby increasing the length of the traction member 3 that can be wound around the winding wheel member 4 to a certain extent, so that the winding wheel member 4 can rotate at most five times to move the clothes drying rod member 30 a distance corresponding to the maximum lifting stroke. When the maximum lifting stroke of the clothes drying rod member 30 is constant, the length of the portion of the winding wheel member 4 used for winding the traction member 3 in the axial direction can be reduced to a certain extent, thereby facilitating the reduction of the axial dimension of the winding wheel member 4 and facilitating the reduction of the thickness dimension of the entire driving device 10, that is, the thinning design of the driving device 10 is realized to a certain extent, thereby saving the occupied space of the driving device 10 to a certain extent, and meeting the structural space requirements.

[0048] In some embodiments, the outer circumference of the winding wheel 4 is between 1 / 3 and 1 / 2 times of the maximum lifting stroke of the clothes drying rod 30 .

[0049] In this way, the length of the traction member 3 that can be wound around the winding wheel 4 can be further increased, so that the clothes drying rod 30 can be moved a distance corresponding to the maximum lifting stroke by rotating the winding wheel 4 two to three times, thereby further reducing the axial dimension of the winding wheel 4 and the thickness of the entire driving device 10, and to a certain extent, further saving the space occupied by the driving device 10.

[0050] In some embodiments, reference Figures 2 to 4 As shown, the driving structure 2 includes a driving member 21 and a transmission assembly 22. The transmission assembly 22 is connected between the driving member 21 and the winding wheel member 4, and the driving member 21 is used to drive the transmission assembly 22 to rotate, so as to drive the winding wheel member 4 to rotate.

[0051] In this way, when the driving member 21 is controlled to work, the transmission assembly 22 can rotate under the drive of the driving member 21, and drive the winding wheel member 4 to rotate, thereby realizing the winding of the traction member 3 on the winding wheel member 4, achieving the purpose of lifting and lowering the clothes drying rod member 30, and being easy to use.

[0052] Exemplarily, the transmission assembly 22 can achieve a rotational connection with the clothes drying rack, for example, by the cooperation of a shaft and a shaft hole.

[0053] In some embodiments, reference Figures 1 to 4 As shown, the driving member 21 has an output shaft 211, and the rotation axis of the output shaft 211 is arranged horizontally. In a plane perpendicular to the lifting direction of the clothes drying rod 30, the transmission assembly 22 is located between the winding wheel 4 and the output shaft 211. The plane perpendicular to the lifting direction of the clothes drying rod 30 is specifically Figures 1 to 4 The XOY plane is shown.

[0054] This arrangement realizes, to a certain extent, the arrangement of the transmission assembly 22, the winding wheel 4 and the driving member 21 on the horizontal plane, which is more convenient than making the above three structures along the lifting direction of the clothes drying rod ( Figures 1 to 4 In the Z direction of the embodiment, the above arrangement can reduce the transmission assembly 22, the winding wheel member 4 and the driving member 21 as a whole to a certain extent. Figures 1 to 4 The dimension in the Z direction of the driving device 10 is reduced, thereby further reducing the thickness of the driving device 10 and saving the driving device 10 in Figures 1 to 4 The required structural space in the Z direction.

[0055] In some embodiments, reference Figures 2 to 4 As shown, along the rotation axis of the winding wheel member 4, the axial dimension of the winding wheel member 4 is not greater than the axial dimension of the transmission assembly 22.

[0056] Such an arrangement can, on the basis of reducing the thickness of the driving device 10, also prevent the winding wheel 4 from protruding axially beyond the transmission assembly 22 to a certain extent, thereby protecting the winding wheel 4 to a certain extent and preventing interference between the winding wheel 4 and other surrounding components to a certain extent, thereby ensuring the normal use of the clothes drying rack.

[0057] In some embodiments, reference Figures 2 to 4As shown, the outer wall of the output shaft 211 in the driving member 21 has a driving tooth. The transmission assembly 22 has a first transmission tooth, which is matched and meshed with the driving tooth, so that the transmission assembly 22 rotates under the drive of the driving member 21.

[0058] In this way, the transmission coordination between the driving member 21 and the transmission assembly 22 can be achieved through the meshing between the first transmission teeth and the driving teeth, so that the transmission process between the driving member 21 and the transmission assembly 22 is smooth and reliable, and the transmission method is simple. Moreover, compared with the use of belt drive, chain drive and other methods, the above-mentioned setting of the present scheme also makes the coordination between the driving member 21 and the transmission assembly 22 compact, thereby improving the structural compactness of the driving device 10, which is beneficial to further save the occupied space of the driving device 10 and further meet the structural space requirements of the driving device 10.

[0059] In some embodiments, the lead angle of the driving tooth is smaller than the equivalent friction angle of the first transmission tooth to prevent the transmission assembly 22 from driving the output shaft 211 to rotate.

[0060] In this way, friction can be formed between the output shaft 211 and the transmission component 22 to achieve self-locking between the output shaft 211 and the transmission component 22, that is, the transmission component 22 can only rotate under the drive of the output shaft 211, and the output shaft 211 cannot rotate under the drive of the transmission component 22. For example, when the load of clothes on the clothes drying rod 30 acts on the transmission component 22 through the traction member 3 and the winding wheel member 4, the friction between the output shaft 211 and the transmission component 22 will apply a resistance torque to the transmission component 22, making it impossible for the transmission component 22 to continue to rotate under the action of the load such as clothes, thereby avoiding the accidental drop of the winding wheel member 4 during use to a certain extent, and meeting and ensuring the hanging weight requirement of the clothes drying rod 30.

[0061] In some embodiments, reference Figures 2 to 4 As shown, the transmission ratio between the transmission assembly 22 and the winding wheel member 4 is greater than 1.

[0062] This can achieve deceleration and torque increase of the winding wheel 4 to a certain extent, thereby improving the stability of the rotation of the winding wheel 4.

[0063] In some embodiments, reference Figures 2 to 4 As shown, the transmission assembly 22 includes a first transmission member 221 and a second transmission member 222 connected to one axial side of the first transmission member 221. The first transmission member 221 is in transmission cooperation with the driving member 21, and the second transmission member 222 is in transmission cooperation with the winding wheel member 4.

[0064] In this way, by controlling the operation of the driving member 21 , the first transmission member 221 is rotated, and at the same time, the second transmission member 222 rotates synchronously with the first transmission member 221 , and drives the winding wheel member 4 to rotate, thereby realizing the winding of the traction member 3 .

[0065] Among them, the above-mentioned first transmission teeth are specifically arranged on the periphery of the first transmission member 221. For example, the second transmission teeth can also be arranged on the periphery of the second transmission member 222, and matching teeth that can match and engage with the second transmission teeth are arranged on the periphery of the winding wheel member 4 to achieve transmission cooperation between the second transmission member 222 and the winding wheel member 4.

[0066] Such an arrangement can improve the stability and reliability of the transmission of the transmission assembly 22 between the driving member 21 and the winding wheel member 4 to a certain extent, thereby improving the winding stability of the traction member 3, which is beneficial to improving the user experience. Moreover, the meshing of the second transmission teeth and the matching teeth improves the structural compactness between the winding wheel member 4 and the transmission assembly 22, which is beneficial to further save the occupied space of the driving device 10. In addition, the tooth top circle diameter of the winding wheel member 4 can also be made larger than the tooth top circle diameter of the transmission assembly 22.

[0067] The first transmission teeth can be helical teeth, for example, the first transmission member 221 can be a helical gear member, so that a structure similar to a worm gear can be formed between the first transmission member 221 and the output shaft 211. In addition, the second transmission member 222 and the winding wheel member 4 can also be spur gear members.

[0068] In some embodiments, reference Figures 2 to 5 As shown, the winding wheel 4 includes a transmission wheel portion 41 and a winding portion 42 connected to one side of the transmission wheel portion 41. The transmission wheel portion 41 cooperates with the transmission assembly 22, and one end of the traction member 3 is connected to the winding portion 42 and can be wound on the winding portion 42. The outer contour circumference of the winding portion 42 is not less than 1 / 5 times the maximum lifting stroke of the clothes drying rod 30.

[0069] Exemplarily, the mating teeth may be specifically on the transmission wheel portion 41 , so that the transmission wheel portion 41 and the second transmission member 222 can be mated in transmission.

[0070] In this way, the parts of the traction member 3 and the winding wheel member 4 used for transmission cooperation with the transmission assembly 22 are isolated to a certain extent, thereby avoiding to a certain extent the situation where the winding of the traction member 3 affects the transmission between the winding wheel member 4 and the transmission assembly 22, improving the smoothness of the transmission between the transmission wheel part 41 and the transmission assembly 22, and allowing the traction member 3 to be smoothly wound, thereby improving the user experience.

[0071] Reference Figures 2 to 5As shown, the projection of the winding portion 42 on the transmission wheel portion 41 can be located within the area surrounded by the outer contour of the transmission wheel portion 41, which can further improve the transmission stability between the transmission wheel portion 41 and the transmission assembly 22 and improve the smoothness of the winding of the traction member 3.

[0072] In some embodiments, reference Figures 2 to 4 As shown, when the transmission assembly 22 is located between the winding portion 42 and the output shaft 211 on a plane perpendicular to the lifting direction of the clothes drying rod 30 , the winding portion 42 and the first transmission member 221 are located on the same side of the transmission wheel portion 41 .

[0073] Compared with the solution of arranging the winding part and the first transmission member on opposite sides of the transmission wheel part in the axial direction, this arrangement can further reduce the transmission assembly 22, the winding wheel member 4 and the driving member 21 as a whole. Figures 1 to 4 The dimension in the Z direction of the driving device 10 is reduced, thereby further reducing the thickness of the driving device 10 and saving the driving device 10 in Figures 1 to 4 The required structural space in the Z direction.

[0074] In some embodiments, reference Figures 2 to 5 As shown, when the transmission wheel portion 41 and the second transmission member 222, and the output shaft 211 and the first transmission member 221 are all driven by tooth meshing, it is also possible to Figures 1 to 4 On the XOY plane shown, the outer contour dimensions of the first transmission member 221 and the outer contour dimensions of the second transmission member 222 are different to avoid the first transmission member 221 affecting the cooperation between the second transmission member 222 and the transmission wheel portion 41 .

[0075] Specifically, in this embodiment, the first transmission member 221 is Figures 1 to 4 The outer contour size on the XOY plane shown is larger than the second transmission member 222 on the Figures 1 to 4 The outer contour dimensions on the XOY plane are shown.

[0076] At the same time, when the projection of the winding portion 42 on the transmission wheel portion 41 is located within the area surrounded by the outer contour of the transmission wheel portion 41, normal winding of the traction member 3 on the winding portion 42 and normal transmission of the first transmission member 221 can also be ensured.

[0077] In some embodiments, reference Figure 1 to Figure 2 As shown, there are two traction members 3, and such an arrangement can improve the stability of the clothes drying rod 30 when it is raised or lowered to a certain extent.

[0078] In some embodiments, reference Figures 2 to 4As shown, there are two winding wheel members 4, and they are arranged one by one with the traction members. The driving structure 2 has two output shafts 211, and one output shaft 211 corresponds to one winding wheel member 4. This arrangement can improve the synchronization of the two traction members 3 when winding on the winding wheel member 4 to a certain extent, thereby improving the stability of the clothes drying rod member 30 and the loads such as clothes on the clothes drying rod member 30 when moving to a certain extent, and improving the user experience.

[0079] Exemplarily, the driving member 21 has two output shafts 211, and there are two transmission components 22, and one transmission component 22 is correspondingly connected between one output shaft 211 and one winding wheel component 4. The driving member 21 can be a double-headed motor, and the two output heads of the double-headed motor are correspondingly formed into two output shafts 211. Alternatively, the driving member 21 can also be a single-headed motor, and two adapter shafts corresponding to the winding wheel component 4 and the traction component 3 are connected to the output head of the single-headed motor, and the adapter shaft is formed as the output shaft 211 of the driving member 21.

[0080] Of course, in other implementations, the driving member 21 may also be a crank rocker mechanism or the like.

[0081] In some embodiments, reference Figure 1 to Figure 2 As shown, the driving device 10 further includes a housing 1. The housing 1 includes an outer shell 11 and a bottom shell 12 detachably connected to the outer shell 11. The bottom shell 12 and the outer shell 11 together enclose a receiving cavity 13, and the driving structure 2 and the winding wheel 4 are both located in the receiving cavity 13, and an avoidance hole 131 is opened on the cavity wall of the receiving cavity 13 for the traction member 3 to pass through so as to be connected to the clothes drying rod 30.

[0082] With this arrangement, the drive structure 2, the winding wheel 4 and other structures can be protected to a certain extent by the outer shell 11 and the bottom shell 12, which is conducive to ensuring the stable output of the drive device 10 and improving the convenience of using the clothes drying rack. At the same time, by making the bottom shell 12 and the outer shell 11 detachably connected, on the one hand, it is convenient to repair, replace, clean, etc. the structure in the accommodating cavity 13; on the other hand, when one of the bottom shell 12 and the outer shell 11 is damaged, only the damaged part needs to be replaced, avoiding the overall scrapping of the bottom shell 12 and the outer shell 11, which is conducive to saving the cost of repair and use.

[0083] The bottom shell 12 and the outer shell 11 can be detachably connected by means of screws, buckles, etc.

[0084] Exemplarily, the driving structure 2 can be connected to the bottom shell 12 , and the transmission assembly 22 is specifically rotatably matched with the bottom shell 12 .

[0085] In a specific implementation, a support member for supporting the bottom shell 12 and the outer shell 11 can be arranged in the accommodating cavity 13, and the two ends of the support member can be respectively connected to the bottom shell 12 and the outer shell 11 to ensure the stability of the overall shape of the accommodating cavity 13 and avoid deformation of the accommodating cavity 13 and pressure loss of the structure inside the accommodating cavity 13.

[0086] Continue to refer to Figures 1 to 5 As shown, this embodiment also provides a clothes drying system, including a clothes drying rack and a driving device 10 for the clothes drying rack.

[0087] The driving device 10 for the clothes drying rack in this embodiment has the same structure and implementation principle as the driving device 10 for the clothes drying rack provided in the above embodiment, and can bring the same or similar technical effects, and reference can be made to the description of the above embodiment.
