[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0038] The following disclosure provides many different embodiments or examples for implementing different structures of the present application. To simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present application. In addition, the present application may repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides examples of various specific processes and materials, but those of ordinary skill in the art can recognize the applicability of other processes and / or the use of other materials.

[0039] For ease of description, spatially relative relationship terms may be used in the text to describe the relative positional relationship or movement of one element or feature shown in the figure relative to another element or feature. These relative relationship terms are, for example, "inside", "outside", "inner side", "outer side", "below", "beneath", "above", "over", "front", "rear", etc. Such spatially relative relationship terms are intended to include different orientations of the device in use or operation other than the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or attitude change or change in motion state, then these directional indications will change accordingly. For example, an element described as "below" or "beneath" other elements or features will then be oriented as "above" or "over" other elements or features. Thus, the exemplary term "below" can include both upper and lower orientations. The device may be oriented otherwise (rotated 90 degrees or in other directions) and the spatially relative relationship descriptors used in the text are interpreted accordingly.

[0040] See Figures 1 to 9 , an embodiment of the present application provides a winding wheel, including a transmission member 100 and a winding member 200. The transmission member 100 is coaxially connected to the winding member 200. A wire guiding groove spirally wound along its own axial direction Y is convexly provided on the outer peripheral wall of the winding member 200. In the axial direction Y of the winding member 200, the included angle φ between the connecting lines of the two notches and the bottom of the wire guiding groove is 8° to 12°.

[0041] In this embodiment, the winding wheel 10 is configured as a combined component that includes at least a transmission member 100 and a winding member 200. The transmission member 100 is coaxially connected to the winding member 200. The outer peripheral wall of the winding member 200 is provided with a wiring groove that is spirally distributed along the axial direction Y of the winding member 200. In this way, flexible members such as wire ropes housed in the wiring groove are also spirally distributed. At this time, the transmission member 100 can be driven to rotate by an external driving component, thereby driving the winding member 200 to rotate, and further driving the flexible member wound on the winding member 200 to be taken out of the wiring groove and stretched, so as to realize the lowering of the clothes-drying bracket connected to the free end of the flexible member, and the user can hang the clothes to be dried on the clothes-drying bracket; after the clothes to be dried are dried, the external driving component is reversed or rotated in the reverse direction to drive the transmission member 100 to rotate in the reverse direction, thereby driving the winding member 200 to rotate in the reverse direction, and further driving the flexible member connected to the winding member 200 to be rolled up in the wiring groove according to the groove, so as to realize the ascent of the clothes-drying bracket, so that the clothes to be dried are completed at a specified height. At the same time, the angle φ between the two notches of the wiring groove and the line connecting the groove bottom is configured to be between 8° and 12°, so that the wiring groove can take into account the storage performance, reduce the noise generated by the flexible part colliding with the wiring groove wall when winding the flexible part, and improve the user experience; and can make the flexible part fall smoothly into the wiring groove, reduce the collision or crushing of the wiring groove wall, reduce the wear or damage of the flexible part caused by the collision, and extend the service life of the winding wheel 10. For example, but not limited to, the angle φ between the two notches of the wiring groove and the line connecting the groove bottom is 10°.

[0042] In one example, the transmission member 100 can be a disc gear structure, and a transmission tooth is provided on the outer peripheral wall of the transmission member 100, and the transmission tooth extends along the axial direction Y of the transmission member 100. The transmission tooth can be engaged with the worm, so that the worm connected to the output end of the motor can be driven to rotate by driving the external motor, thereby driving the transmission member 100 engaged with the worm to rotate. The winding member 200 can be a hollow cylindrical structure, and the radial X dimension of the transmission member 100 is greater than the radial X dimension of the winding member 200, and the axial Y dimension of the winding member 200 is greater than the axial Y dimension of the transmission member 100. In this way, the storage space of the flexible member is ensured, and at the same time, the structure of the entire winding wheel 10 is compact and simple, and convenient for processing. The groove depth of the wiring groove is greater than or equal to the diameter of the flexible member. In actual production, in order to reduce the wear on the outer side of the flexible member, the groove depth of the wiring groove is generally configured to be slightly greater than the diameter of the flexible member.

[0043] In one example, for the convenience of processing, the transmission member 100, the winding member 200 and the wire routing groove are integrally formed, so as to improve the aesthetics of the entire winding wheel 10 and extend the service life of the winding wheel 10.

[0044] In one example, to improve the aesthetics, the transmission member 100 and the winding member 200 can be coaxially arranged. Of course, in other embodiments, the winding member 200 can also be non-coaxially arranged with the transmission member 100 so that the entire winding wheel 10 can adapt to different installation spaces.

[0045] In a possible implementation, a wire guiding tooth 300 protrudes between two adjacent wire grooves, and a rounded corner structure R is provided on the side of the wire guiding tooth 300 away from the winding member 200. With this arrangement, the mechanical impact of the flexible member on the wire guiding tooth 300 can be reduced, the service life of the winding wheel 10 can be extended, and at the same time, the flexible member can fall into the wire groove more smoothly.

[0046] As Figure 3 and Figure 4 shown, the wire guiding tooth 300 can be a long strip structure of continuous spiral winding. To reduce the sharp points and burrs on the wire guiding tooth 300, a rounded corner structure R is provided on the wire guiding tooth 300. The rounded corner structure R can make the sharp part of the wire guiding tooth 300 smooth. In this way, even if the flexible member impacts on it, it can fall to the bottom of the wire groove along its smooth surface, avoiding the flexible member from being scratched / severed.

[0047] In a possible implementation, one end of the winding member 200 close to the transmission member 100 is provided with a mounting end hole 210 and a guiding groove 220. The mounting end hole 210 extends along the radial direction X of the winding member 200 and penetrates the side wall of the winding member 200, and the guiding groove 220 extends along the axial direction Y of the winding member 200 and penetrates the side wall of the winding member 200. The mounting end hole 210 is communicated with the starting end of the wire groove formed by enclosing the wire guiding tooth 300 and the transmission member 100 through the guiding groove 220. With this arrangement, the starting end of the flexible member can be hidden and received in the side wall and the inner cavity of the winding member 200, avoiding the starting end of the flexible member from protruding out of the wire groove or the wire guiding tooth 300, reducing the interference of the flexible member during wire routing, and reducing the noise generated during the winding process.

[0048] As Figure 2 、 Figure 3 、 Figure 5 and Figure 6As shown, the installation end hole 210 is a central hole penetrating the side wall of the winding member 200, and the guiding groove 220 is a long hole penetrating the side wall of the winding member 200. One end of the guiding groove 220 communicates with the installation end hole 210, and the other end communicates with the starting end of the wire routing groove. The solder head at the starting end of the flexible member is inserted from the outside of the winding member 200 and extends at least partially into the inner cavity of the winding member 200 to achieve a fixed connection to the starting end of the flexible member. Then, the flexible member transitions along the guiding groove 220 to the starting end of the wire routing groove and winds along the groove of the wire routing groove. The flexible member at the installation end hole 210 is received in the thickness space of the side wall of the winding member 200 and the inner cavity of the winding member 200, and the flexible member at the guiding groove 220 is received in the thickness space of the side wall of the winding member 200 without occupying the wire routing groove space. In this way, the wear of the flexible member at the end by the flexible member at other parts during the winding process can be effectively reduced, and the service life of the flexible member can be extended. It should be understood that the starting end of the wire routing groove is located between the installation end hole 210 and the transmission member 100, and the guiding groove 220 is located between the starting end of the wire routing groove and the installation end hole 210.

[0049] In a possible implementation manner, the projected area of the installation end hole 210 on the transmission member is larger than the projected area of the guiding groove 220 on the transmission member 100; and / or, a chamfer structure is provided at one end of the guiding groove 220 away from the installation end hole 210, and the chamfer structure is close to the starting end of the wire routing groove. With such a setting, on the one hand, the end of the steel wire rope can be stably fastened in the installation end hole 210 and the guiding groove 220 through the dimensional difference between the installation end hole 210 and the guiding groove 220 to prevent the steel wire rope from falling off; on the other hand, a chamfer structure is provided at the bending part of the steel wire rope to reduce the sharp points and burrs at the connection between the guiding groove 220 and the starting end of the wire routing groove, avoid the steel wire rope from being cut / severed, and enable the steel wire rope to smoothly transition to the wire routing groove, thereby extending the service life of the steel wire rope.

[0050] In a possible implementation manner, a wire routing groove 230 is provided on the winding member 200, the wire routing groove 230 is located at the starting end of the wire routing groove, and the winding wheel 10 further includes a first reinforcing member 400, and the first reinforcing member 400 is disposed on the inner wall of the winding member 200 corresponding to the wire routing groove 230.

[0051] In this embodiment, the specific configuration of the wire winding wheel 10 is further optimized. Specifically, the wire winding wheel 10 is configured as a combined component including at least a transmission member 100, a wire winding member 200, and a first reinforcing member 400. A wire guiding groove 230 is provided at the starting end of the wire routing groove to facilitate the transition of the flexible member extended from the guiding groove 220, avoid the formation of bulges or misalignments of the flexible member at the starting end of the wire routing groove, and improve the smoothness of wire routing. The first reinforcing member 400 is disposed in the inner cavity of the wire winding member 200 and corresponds to the wire guiding groove 230. In this way, the reduced radial thickness of the wire winding member 200 at the wire guiding groove 230 can be compensated, the radial thickness at the wire guiding groove 230 can be enhanced, the overall strength of the wire winding member 200 can be improved, and the service life of the wire winding member 200 can be extended.

[0052] In a possible implementation manner, in the wire routing direction of the wire routing groove, the radial thickness of the wire guiding groove 230 becomes smaller and smaller; and / or in the wire routing direction of the wire routing groove, the radial thickness of the first reinforcing member 400 becomes smaller and smaller. With such a setting, not only can good accommodation of the end flexible member be achieved, the radial thickness and rigidity of the wire winding member 200 be ensured, but also the overall structure of the wire winding wheel 10 can be simplified and the overall weight can be reduced.

[0053] As Figure 2 、 Figure 3 and Figure 5 shown, the wire guiding groove 230 can be an arc-shaped groove structure with a non-uniform thickness that is deep to shallow in the wire routing direction, and the first reinforcing member 400 can be an arc-shaped convex block structure with a non-uniform thickness that is thick to thin in the wire routing direction. In this way, the weight of the wire winding wheel 10 can be minimized, and a delicate and miniaturized layout of the wire winding wheel 10 can be realized. It should be understood that the radial thickness of the wire guiding groove 230 refers to the groove depth of the wire guiding groove 230 in the radial direction X of the wire winding wheel 10, and the radial thickness of the first reinforcing member 400 refers to the thickness size of the first reinforcing member 400 in the radial direction X of the wire winding wheel 10.

[0054] In a possible implementation manner, it further includes a connecting member 500 and a plurality of second reinforcing members 600 disposed in the wire winding member 200. One end of the connecting member 500 is connected to the transmission member 100, and the other end is suspended; the plurality of second reinforcing members 600 are arranged at intervals along the circumference of the connecting member 500 between the connecting member 500 and the wire winding member 200.

[0055] In this embodiment, the specific configuration of the winding wheel 10 is further optimized. Specifically, the winding wheel 10 is configured as a composite component including at least a transmission member 100, a winding member 200, a connecting member 500 and a plurality of second reinforcing members 600. The connecting member 500 may be a cylindrical sleeve-shaped structure, the radial X dimension of the connecting member 500 is smaller than the radial X dimension of the winding member 200, the axial Y dimension of the connecting member 500 is smaller than the axial Y dimension of the winding member 200, and the axis of the connecting member 500 may be the same as the axis of the winding member 200. The second reinforcing member 600 may be an irregular plate-shaped structure, the first side of the second reinforcing member 600 is a plane, which may be connected to the transmission member 100 by welding; the two side surfaces adjacent to the first side of the second reinforcing member 600 may be arc surfaces, which may be connected to the outer wall of the connecting member 500 and the outer wall of the winding member 200 by welding, respectively. The connecting member 500 is used to be sleeved on the rotating shaft 30 of the connecting seat 20 to prevent the winding wheel 10 from being misplaced / shifted during the winding process, thereby improving the rotation stability and reducing the rotation noise.

[0056] In a possible implementation, the second reinforcement member 600 is tilted on the side away from the transmission member 100, and the axial length Y of the second reinforcement member 600 gradually increases in the direction from the connecting member 500 to the winding member 200. In this way, a relief area can be formed on the side of the second reinforcement member 600 away from the transmission member 100, which is convenient for subsequent assembly and use.

[0057] like Figure 3 and Figure 5 As shown, the second side of the second reinforcement member 600 is an inclined surface, and the plurality of second reinforcement members 600, the connecting member 500 and the winding member 200 form a avoidance area similar to a lampshade space on one end of the winding member 200 away from the transmission member 100. The avoidance area can avoid the rotating shaft 30 on the connecting seat 20 for movably connecting the winding wheel 10 and the arc-shaped boss arranged at the bottom of the mounting recess 22 of the connecting seat 20, so as to prevent the winding wheel 10 from being disturbed by the connecting seat 20 during the rotation process and reduce the noise during the rotation process.

[0058] See also Figures 7 to 9 On the second aspect, the present application also provides a power system, including a driving assembly, a connecting seat 20 and the winding wheel 10 as described above, the connecting seat 20 is provided with a wire outlet 21, the winding wheel 10 is movably connected to the connecting seat 20, and the wire outlet end of the winding wheel 10 is arranged corresponding to the wire outlet 21, and the output end of the driving assembly is connected to the transmission member 100 of the winding wheel 10.

[0059] In this embodiment, the specific configuration of the power system is optimized. Specifically, the power system is configured to include at least a combined component of a driving component, a connecting seat 20, and a wire winding wheel 10. The connecting seat 20 includes a first mounting portion and a second mounting portion provided on the outer wall of the first mounting portion. The first mounting portion can be a cylindrical structure for mounting the wire winding wheel 10. A plurality of reinforcing ribs are provided on the outer peripheral wall of the first mounting portion to enhance the rigidity of the entire first mounting portion. At least one connecting ear is further provided on the outside of the first mounting portion, and the connecting seat 20 is connected to the drying host through the connecting ear. The driving component includes a driving member and a worm. The driving member can be a motor, and the driving member can be connected to the second mounting portion through fasteners such as screws / bolts. The worm is inserted through the first mounting portion and meshes with the transmission member 100 of the wire winding wheel 10. The worm is connected to the output end of the driving member. In this way, the motor can be used to drive the worm to rotate, thereby driving the transmission member 100 meshing with the worm to rotate, and the winding member 200 connected to the transmission member 100 rotates accordingly, and the flexible member wound on the winding member 200 is taken out and extended or wound up.

[0060] In one example, as Figure 7 shown, two first mounting portions are arranged on the connecting seat 20, the two first mounting portions are arranged side by side, and the second mounting portion is connected to the outer walls of the two first mounting portions at the same time. Two wire winding wheels 10 are provided, and the two wire winding wheels 10 are respectively inserted into the two first mounting portions. The worm meshes with the transmission members 100 of the two wire winding wheels 10 at the same time. In this way, two wire winding wheels 10 can be driven to rotate by one motor, so as to realize the synchronous lowering or rising of both ends of the drying bracket, and improve the stability of the drying operation.

[0061] In addition, the specific structure of the wire winding wheel 10 refers to the above-mentioned embodiment. Since this power system adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, and will not be elaborated one by one here.

[0062] In a possible implementation manner, an installation sink 22 is provided on the connecting seat 20. A rotating shaft 30 and a third reinforcing member 40 are provided at the bottom of the installation sink 22. The rotating shaft 30 extends along the axial direction Y of the wire winding wheel 10. The third reinforcing member 40 is spaced around the periphery of the rotating shaft 30. The wire winding wheel 10 is embedded in the installation sink 22. The connecting member 500 of the wire winding wheel 10 is sleeved outside the rotating shaft 30. The third reinforcing member 40 corresponds to the avoidance area formed by enclosing the connecting member 500 and a plurality of second reinforcing members 600 of the wire winding wheel 10; and / or, the connecting seat 20 is provided with a communicating installation sink 22 and an avoidance side groove 23, and the avoidance side groove 23 is located outside the installation sink 22. With such a setting, the connection tightness between the connecting seat 20 and the wire winding wheel 10 can be strengthened, and the assembly of the wire winding wheel 10 is also facilitated.

[0063] As Figure 8 andFigure 9 As shown, the size of the installation groove 22 is adapted to the size of the winding wheel 10 so that the winding wheel 10 can be movably connected to the connecting seat 20. The rotating shaft 30 and the third reinforcement 40 are arranged at the bottom of the installation groove 22. The rotating shaft 30 can be a solid cylinder, and the third reinforcement 40 can be a double-layer 3 / 4 circular boss and two end triangular plates, which are used to strengthen the rigidity of the rotating shaft 30. When the winding wheel 10 is embedded in the installation groove 22, the connecting member 500 of the winding wheel 10 is sleeved on the outside of the rotating shaft 30, and the third reinforcement 40 corresponds to and is spaced from the second end of the plurality of second reinforcements 600 to avoid mutual interference, reduce rotation noise, and improve the winding operation stability of the winding wheel 10. In addition, an avoidance side groove 23 is arranged on the outside of the installation groove 22 to facilitate the installation and removal of the winding wheel 10 and facilitate subsequent maintenance.

[0064] In a third aspect, the present application also provides a clothes drying machine, comprising the power system as described above. The specific structure of the power system refers to the above embodiments. Since the clothes drying machine adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.
