Detailed Implementation

[0031] To better understand the above-mentioned objectives, features, and advantages of the embodiments of this utility model, the solutions of the embodiments of this utility model will be further described below. It should be noted that, unless otherwise specified, the embodiments of this utility model and the features thereof can be combined with each other.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the embodiments of the present invention, but the embodiments of the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the present invention, and not all embodiments.

[0033] To address the problems of complex manufacturing processes, low production efficiency, and high costs associated with existing motor pulleys, referring to... Figures 1 to 3 As shown, this embodiment provides a motor pulley that transmits the rotational power of the motor to the pulsator via a belt, enabling the pulsator to rotate and thus realizing the washing and spin-drying operations of the pulsator washing machine. Specifically, the motor pulley includes a pulley 100, a connecting body 200, and a fan blade assembly 300.

[0034] Specifically, refer to Figure 1 and Figure 2 As shown, the fan blade assembly 300 is connected to one side of the connecting body 200 and is integrally formed with the connecting body 200, and the pulley 100 is riveted to the side of the connecting body 200 opposite to the fan blade assembly 300.

[0035] In other words, the fan blade assembly 300 and the pulley 100 are located on opposite sides of the connecting body 200. After the fan blade assembly 300 and the connecting body 200 are integrally formed by stamping, the pulley 100 is riveted to the connecting body 200. The entire assembly operation is simple, quick, and low in cost.

[0036] Specifically, refer to Figure 1 As shown, the fan blade assembly 300 may include a plurality of fan blades 310, which are spaced apart circumferentially along the connecting body 200, and each fan blade 310 extends in a direction away from the pulley 100 for functions such as heat dissipation. For example, the fan blades 310 may be configured as follows: Figure 1 The eight shown can also be set to six or other numbers. For example, the fan blades 310 and the connecting body 200 can be made of iron or aluminum.

[0037] For example, the connecting body 200 can be presented as follows: Figure 1 The disk shape shown.

[0038] As can be seen from the above, the motor pulley of this embodiment includes a pulley 100, a connecting body 200, and a fan blade assembly 300. By connecting the fan blade assembly 300 to one side of the connecting body 200 and integrally forming it with the connecting body 200, and riveting the pulley 100 to the side of the connecting body 200 opposite to the fan blade assembly 300, a complete motor pulley can be formed. Compared with the assembly operation of welding the fan blade assembly 300 to the connecting body 200 and then screwing the pulley 100 to the connecting body 200, this embodiment of the utility model directly rivets the fan blade assembly 300 and the connecting body 200 to the pulley 100 after integral forming. The entire assembly operation is simple and quick, and can effectively reduce the labor assembly cost.

[0039] In specific implementation, the angle between the fan blade 310 and the connecting body 200 is greater than or equal to 30° and less than or equal to 90°. This design ensures that when the fan blade 310 rotates, it has sufficient surface area in the direction perpendicular to the connecting body 200 to drive more air movement, guaranteeing airflow and thus improving heat dissipation. Furthermore, the angle between the fan blade 310 and the connecting body 200 is greater than or equal to 30° and less than or equal to 85°, which, while ensuring heat dissipation, prevents excessive motor wear due to excessive wind resistance during fan blade rotation, thereby improving the transmission efficiency of the motor pulley.

[0040] It should be noted that the included angle between the fan blade 310 and the connecting body 200 can also be less than 30°, and can be set according to actual needs. As long as heat dissipation efficiency is guaranteed and the motor pulley can have good transmission efficiency, this utility model embodiment does not limit this.

[0041] Reference Figure 3 As shown, in some embodiments, the connecting body 200 is provided with an assembly groove 201 on the side facing the pulley 100, and the pulley 100 is provided with a connecting part 101 on the side facing the connecting body 200. The connecting part 101 extends into the assembly groove 201, and part of the connecting part 101 can be bent and deformed under the action of external force to form a rivet structure that is riveted in the assembly groove 201, so that after the rivet structure is riveted in the assembly groove 201, the two are reliably connected.

[0042] For example, when the thickness of the connecting body 200 is small, the assembly groove 201 can be formed by directly applying pressure to the connecting body 200 to make part of the connecting body 200 recessed downwards; or when the thickness of the connecting body 200 is large, the assembly groove 201 can also be formed by hollowing out part of the connecting body 200.

[0043] A connecting part 101 is provided on the side of the pulley 100 facing the connecting body 200. When it is necessary to achieve the riveting fit between the connecting body 200 and the pulley 100, the connecting part 101 is inserted into the assembly groove 201. After applying sufficient pressing pressure to the pulley 100, part of the connecting part 101 is bent and deformed to form a rivet structure riveted in the assembly groove 201. That is, the rivet structure and the assembly groove 201 are interference fit, thereby achieving a quick and reliable connection between the two.

[0044] Reference Figure 3 As shown, in some embodiments, the assembly groove 201 is an annular groove extending circumferentially along the connecting body 200, the connecting part 101 is a cylindrical structure adapted to the annular groove, and the connecting part 101 is located on the outer edge of the pulley 100 and is concentrically arranged with the pulley 100.

[0045] In specific implementation, in order to further enhance the riveting stability of the connecting body 200 and the pulley 100, the assembly groove 201 can be set as an annular groove. At this time, the connecting part 101 is also an annular cylindrical structure. During assembly, at least part of the cylindrical structure extends into the annular groove and then bends and deforms under the action of external force to form an annular rivet structure that rivets with the annular groove, thereby increasing the riveting contact area between the two and thus enhancing the connection stability between them.

[0046] Furthermore, by placing the cylindrical structure on the outer edge of the pulley 100 and setting them concentrically, the overall appearance can be made more aesthetically pleasing, preventing the problem of an unsightly gap between the outer edge of the pulley 100 and the outer wall of the connecting part 101. Placing the cylindrical structure on the outer edge of the pulley 100 also makes it easier for operators to rivet the cylindrical structure into the assembly groove 201.

[0047] Reference Figure 3 As shown, in some embodiments, the connecting portion 101 includes a first cylindrical portion 102 and a second cylindrical portion 103. One end of the first cylindrical portion 102 is connected to the connecting body 200, and one end of the second cylindrical portion 103 is connected to the other end of the first cylindrical portion 102. The second cylindrical portion 103 can be bent relative to the first cylindrical portion 102 under the action of external force to form a rivet structure.

[0048] In a specific implementation, before the connecting part 101 is riveted into the assembly groove 201, the entire connecting part 101 extends along the axial direction of the pulley 100, that is, the first cylindrical part 102 and the second cylindrical part 103 are arranged in parallel. When riveting, after the first cylindrical part 102 and the second cylindrical part 103 are inserted into the assembly groove 201, the second cylindrical part 103 is bent relative to the first cylindrical part 102 under the action of external force to form a rivet structure riveted into the assembly groove 201.

[0049] For example, the second cylindrical portion 103 can be bent relative to the first cylindrical portion 102 toward the center of the connecting portion 101 to form a rivet structure extending radially along the pulley 100, or it can be bent relative to the first cylindrical portion 102 toward the direction away from the center of the connecting portion 101 to form a rivet structure extending radially along the pulley 100. In this embodiment, the second cylindrical portion 103 is bent relative to the first cylindrical portion 102 in a direction away from the center of the connecting portion 101 to form a rivet structure. This design allows the outer diameter of the pulley 100 to be relatively small, thereby saving material costs and achieving a weight reduction design.

[0050] Reference Figure 3 As shown, in some embodiments, the wall thickness of the first cylindrical portion 102 is greater than the wall thickness of the second cylindrical portion 103. This design makes the structural strength of the second cylindrical portion 103 weaker than that of the first cylindrical portion 102, thereby making the second cylindrical portion 103 more prone to bending and deformation, thus making the riveting operation less strenuous.

[0051] For example, the first cylindrical portion 102 and the second cylindrical portion 103 can be integrally formed to save manufacturing steps and improve the structural strength of the entire connecting portion 101.

[0052] Reference Figure 3 As shown, in some embodiments, the outer wall of the rivet structure is fitted to the groove wall of the assembly groove 201. That is, before the riveting operation, the second cylindrical portion 103 extends axially along the pulley 100, and after bending, the second cylindrical portion 103 extends radially along the pulley 100 and fits to the groove wall of the assembly groove 201. This can increase the riveting contact area and improve the riveting reliability.

[0053] Reference Figure 3 As shown, in some embodiments, an overlapping structure 400 is provided between the pulley 100 and the connecting part 101. The overlapping structure 400 is mounted on the connecting body 200. In this way, the overlapping cooperation between the connecting body 200 and the overlapping structure 400 can provide a certain support for the pulley 100, preventing the pulley 100 from deforming and affecting its use when an external force is applied to the pulley 100 and the connecting part 101 is bent and deformed to form a rivet structure.

[0054] Reference Figures 1 to 3 As shown, in some embodiments, the pulley 100 includes a motor connection end 104, a first conical body 105 and a second conical body 106, and the first conical body 105 and the second conical body 106 are sequentially arranged on the motor connection end 104 along the direction from the pulley 100 to the connecting body 200.

[0055] The first cone 105 and the second cone 106 are arranged opposite to each other, the connecting part 101 is arranged on the side of the second cone 106 opposite to the first cone 105, and the overlapping structure 400 is arranged at the connection between the second cone 106 and the connecting part 101.

[0056] Specifically, the motor connection end 104 is provided with a mounting hole 107 that mates with the output shaft of the motor. The first conical body 105 and the second conical body 106 are arranged opposite to each other, so that a V-groove 108 that can accommodate the pulley 100 can be formed between them. Since the structural strength of the connection between the second conical body 106 and the connecting part 101 is relatively weak, the overlapping structure 400 is set at the connection between the second conical body 106 and the connecting part 101, which can increase the structural strength of the connection and prevent fatigue fracture at the connection.

[0057] Reference Figure 3 As shown, in some embodiments, the overlapping structure 400 includes an overlapping block. The side of the overlapping block near the connecting body 200 forms a first overlapping plane 401. A second overlapping plane 202 is formed on the connecting body 200 at a position corresponding to the first overlapping plane 401. The first overlapping plane 401 and the second overlapping plane 202 are in contact, thereby increasing the contact area between the two. This allows the overlapping block to reliably support the pulley 100 and prevent the pulley 100 from deforming under force, thus affecting its use.

[0058] Reference Figure 3 As shown, in some embodiments, the overlapping structure 400 includes multiple overlapping structures 400, which are spaced apart along the circumference of the pulley 100, so that the pulley 100 can be supported at different positions in its circumference by the multiple overlapping structures 400, thereby further improving the support reliability.

[0059] Alternatively, in other implementations, the overlapping structure 400 can be set as a ring structure extending circumferentially along the pulley 100, so that the pulley 100 can be reliably supported at all positions in its circumference, thereby effectively preventing the pulley 100 from deforming.

[0060] For example, the overlapping structure 400 is integrally formed with the pulley 100, which can save manufacturing steps and improve the overall structural strength of the pulley 100.

[0061] Reference Figure 1 and Figure 2 As shown, in some embodiments, the connecting body 200 is provided with a plurality of notches 203, which are spaced apart along the circumference of the connecting body 200, thereby achieving a weight reduction design.

[0062] In addition, refer to Figure 2As shown, a plurality of reinforcing ribs 109 are provided between the first conical body 105 and the motor connection end 104, which are arranged radially and circumferentially along the first conical body 105.

[0063] Reference Figures 1 to 3 As shown, this embodiment also provides a garment processing device, including the aforementioned motor pulley.

[0064] The specific structure and implementation principle of the motor pulley in this embodiment are the same as those of the motor pulley described above, and can bring the same or similar technical effects. They will not be described in detail here, but can be referred to the above description.

[0065] For example, clothing handling equipment can be a top-loading washing machine, a top-loading washer-dryer combo, or a front-loading washing machine.
