Description

Technical Field

[0001] This application relates to the field of garment care technology, and in particular to a vibration damping device and garment processing equipment using the vibration damping device. Background Technology

[0002] During operation, such as in the spin-drying process, garment processing equipment generates vibrations that can negatively impact the user experience. To address this issue, garment processing equipment typically incorporates vibration damping devices between the drum and the base to improve vibration transmission.

[0003] However, the damping force provided by the vibration damping device in the relevant technology is constant, but the entire working stroke of the garment processing equipment includes both large amplitude conditions such as washing, rinsing and low-speed dehydration, and small amplitude conditions such as high-speed dehydration, which makes it impossible for the vibration damping device to match the different amplitude conditions of the garment processing equipment. Utility Model Content

[0004] This application provides a vibration damping device and a garment processing equipment, which can adaptively match the different amplitude operating conditions of the garment processing equipment, effectively improving the overall vibration and noise level of the garment processing equipment.

[0005] In a first aspect, embodiments of this application provide a vibration damping device, which includes a housing, a telescopic shaft, a damping component, and an adjusting component;

[0006] The telescopic shaft is at least partially telescopically inserted into the housing, the damping member is disposed on the outer wall side of the telescopic shaft and can apply a damping force to the telescopic shaft, and the damping member has a first opening that penetrates the damping member radially along the telescopic shaft;

[0007] The adjusting member is connected to the outer shell and surrounds the outer periphery of the damping member. The adjusting member can apply force to the damping member so that the two walls of the first opening facing each other can move closer or further away along the circumference of the telescopic shaft, thereby adjusting the magnitude of the damping force.

[0008] In some embodiments, the first opening also extends through the damping member along the axial direction of the telescopic shaft.

[0009] In some embodiments, the damping element includes a head end and a tail end disposed circumferentially opposite each other along the telescopic shaft, the head end and the tail end being spaced apart in the circumferential direction of the telescopic shaft to cooperate in forming the first opening.

[0010] In some embodiments, the damping element includes at least two damping plates, which are arranged circumferentially spaced along the telescopic axis to cooperate in forming the first opening.

[0011] In some embodiments, two adjacent first openings are the same size along the circumference of the telescopic axis;

[0012] And / or, along the circumference of the telescopic axis, a plurality of the first openings are evenly distributed.

[0013] In some embodiments, the adjusting member is a ring-shaped clamp, and a clamp space is formed between the inner sidewall of the clamp and the outer wall of the telescopic shaft, and the damping member is disposed in the clamp space;

[0014] The size of the clamp space is adjustable so that the two walls facing each other at the first opening can move closer or further apart along the circumference of the telescopic axis.

[0015] In some embodiments, a drive assembly is also included, which is mounted on the housing; the clamp includes an annular body, a first connecting portion, and a second connecting portion;

[0016] The clamping space is formed between the inner wall of the annular body and the outer wall of the telescopic shaft. The first connecting part is connected to one end of the annular body, and the second connecting part is connected to the other end of the annular body and is spaced apart from the first connecting part, so as to cooperate to form a second opening communicating with the clamping space.

[0017] The drive assembly is connected to the second connecting part to drive the first connecting part and the second connecting part to move closer or further apart, so that the size of the clamp space is adjustable.

[0018] In some embodiments, the second connecting portion is provided with a threaded hole, and the driving assembly includes a driving member and a threaded rod;

[0019] The threaded rod is connected to the driving component for transmission, passes through the first connecting part, and is threadedly connected to the threaded hole of the second connecting part;

[0020] Under the drive of the driving member, the threaded rod can be threadedly engaged with the threaded hole, so that the second connecting part is closer to or farther away from the first connecting part.

[0021] In some embodiments, the second connection includes a connecting section and an extension section, the extension section being connected to the connecting section along the axial direction of the threaded rod;

[0022] The threaded hole extends through the connecting section and the extension section.

[0023] In some embodiments, the drive assembly includes a drive member, a nut, and a threaded rod, wherein the nut is fixedly connected to the second connecting portion and has a threaded hole;

[0024] The threaded rod is connected to the driving component, passes through the first connecting part and the second connecting part, and is threadedly connected to the threaded hole of the nut;

[0025] Under the drive of the driving component, the threaded rod can be threadedly engaged with the threaded hole, so that the nut can drive the second connecting part to move closer to or away from the first connecting part.

[0026] In some embodiments, the thickness of the clamp is greater than or equal to the thickness of the damping member along the axial direction of the telescopic shaft.

[0027] In some embodiments, the outer shell includes a main body segment and a mounting segment. One end of the main body segment is used to connect to the barrel body, and the mounting segment is connected to the other end of the main body segment and has an inner diameter larger than the inner diameter of the main body segment, so as to create an installation space at the bottom of the main body segment.

[0028] Both the damping component and the adjusting component are installed within the installation space.

[0029] In some embodiments, the housing further includes a limiting member disposed within the mounting space and connected to the mounting section, the limiting member being located along the axial direction of the damping member on the side of the adjusting member away from the main body section;

[0030] Wherein, along the axial direction of the telescopic shaft, the limiting member is used to abut against the adjusting member and / or the damping member to prevent the adjusting member and / or the damping member from dislodging from the mounting section.

[0031] Secondly, embodiments of this application provide a garment processing device, which includes a base, a tub, and a vibration damping device as described above;

[0032] The barrel is located above the base, the outer shell is connected to the barrel, and the telescopic shaft is connected to the base.

[0033] Based on the vibration damping device and clothing processing equipment of this application embodiment, the damping force is adjusted by applying force to the damping component through the adjusting component, so that the vibration damping device can adapt to different working conditions of the clothing processing equipment. For example, when the clothing processing equipment is in a condition with a large amplitude, the adjusting component can increase the damping force to adapt to the condition with a large amplitude. When the clothing processing equipment is in a condition with a small amplitude, the adjusting component can decrease the damping force to match and adapt to the condition with a small amplitude. In this way, the vibration damping device of this embodiment can effectively improve the vibration and noise level of the entire clothing processing equipment under different working conditions, thereby improving the user experience.

[0034] Furthermore, compared to the overall regular and circular structure of the damping component, the design of the first opening allows the damping component to have a certain deformation margin in the circumferential direction of the telescopic shaft. When the adjusting component applies force to the damping component, it will not be squeezed outward or excessively squeezed outward along the radial direction of the telescopic shaft. This prevents the damping component from being squeezed outward locally or excessively, which would reduce the contact area between the damping component and the telescopic shaft and result in insufficient friction force applied by the damping component to the telescopic shaft, thus ensuring the vibration reduction effect of the vibration reduction device.

[0047] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0048] 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.

[0049] Where the following description relates to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0050] In the description of this application, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0051] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0052] Please see Figure 1 This application discloses a garment processing device, which can be a washing machine, dryer, washer-dryer combo, etc., for washing, dehydrating, and other operations on various types of garments. In the embodiments of this application, the garment processing device includes a base 10, a drum 20, and a vibration damping device 30. The base 10 is supported on the ground or mounting surface and serves to support the vibration damping device 30 and the drum 20.

[0053] The barrel 20 is a structure in the garment processing equipment that is mainly used to provide garment processing functions. Specifically, the barrel 20 defines a garment processing chamber and a loading port that communicates with the garment processing chamber. Garments can be put into the garment processing chamber through the loading port or taken out of the garment processing chamber through the loading port.

[0054] It is understandable that the drum 20 will generate a certain amount of vibration during operation, and this vibration will be further transmitted to the base 10, causing the entire garment processing equipment to vibrate and generate noise, affecting the user experience. Based on this, this embodiment connects a vibration damping device 30 between the base 10 and the drum 20 to suppress the vibration generated by the garment processing equipment during operation, thereby improving the overall vibration and noise level of the garment processing equipment.

[0055] The entire working cycle of the garment processing equipment includes both high-amplitude operations such as washing, rinsing, and low-speed spin-drying, and low-amplitude operations such as high-speed spin-drying. Therefore, to ensure that the vibration damping device 30 can match the different amplitude operating conditions of the garment processing equipment, please refer to [the relevant documentation / reference needed]. Figures 1-4 This application also proposes a vibration damping device 30, which includes a housing 31, a telescopic shaft 32, a damping element 33, and an adjusting element 34.

[0056] The outer casing 31 can be elongated cylindrical to make its shape more regular and easier to process and manufacture. The outer casing 31 can be made of plastic to make it lighter and effectively reduce the overall weight of the vibration damping device 30. Alternatively, it can be made of metal for better structural strength; this embodiment does not impose a specific limitation. The outer casing 31 is connected to the drum 20 of the garment processing equipment, specifically through a rotatable connection.

[0057] The telescopic shaft 32 can be arranged in a circular shaft shape to make its shape more regular and easier to process and manufacture. Furthermore, in addition to being arranged in a circular shaft shape, the telescopic shaft 32 has a radial direction (XX) and an axial direction (YY) that are vertically aligned. The telescopic shaft 32 can be made of metal to have better structural strength and improve the overall strength of the vibration damping device 30. Of course, the telescopic shaft 32 can also be made of plastic; this embodiment does not limit this.

[0058] At least a portion of the telescopic shaft 32 is telescopically inserted into the housing 31. It is understood that, taking a spin-drying operation as an example, before spin-drying, the clothes placed in the garment processing chamber will contain water, making the overall weight of the drum 20 and the clothes relatively heavy. Therefore, the telescopic shaft 32 needs to retract into the housing 31 accordingly. During spin-drying, as the water on the clothes gradually detaches from the clothes and drains out of the drum 20, the overall weight of the drum 20 and the clothes gradually decreases. Therefore, the telescopic rod needs to extend out of the housing 31 accordingly. In some embodiments, one end of the telescopic shaft 32 is telescopically inserted into the housing 31, and the other end of the telescopic rod is used to connect to the base 10 of the garment processing equipment.

[0059] The damping element 33 can be made of rubber or polymer resin, etc., and this embodiment does not limit this. The damping element 33 is disposed on the outer wall side of the telescopic shaft 32 to generate friction on the telescopic shaft 32, thereby applying a damping force to the telescopic shaft 32. In some embodiments, the damping element 33 is disposed on the outer wall of the telescopic shaft 32 to directly apply a damping force to the telescopic shaft 32. In other embodiments, the damping element 33 is disposed on the outside of the telescopic shaft 32, and other components are disposed between the damping element 33 and the outer wall of the telescopic shaft 32, and the damping element 33 indirectly applies a damping force to the telescopic shaft 32 through other components. This embodiment does not limit this.

[0060] Specifically, when the barrel 20 vibrates, the telescopic shaft 32 and the outer shell 31 will move relative to each other along the telescopic direction of the telescopic shaft 32, and thus will be subject to the frictional force of the damping component 33 during the movement, generating a damping force.

[0061] The adjusting member 34 can be made of plastic or metal, and this embodiment does not limit this. The adjusting member 34 is connected to the housing 31 to realize the installation of the adjusting member 34. The adjusting member 34 surrounds the outer periphery of the damping member 33 and can apply force to the damping member 33 to change the magnitude of the damping force.

[0062] In some structural forms, the adjusting member 34 can be a clamping member 341, which changes the magnitude of the damping force by applying different clamping forces to the damping member 33. In other structural forms, the vibration damping device 30 also includes an air pump, and the adjusting member 34 has an inflation chamber. The air pump is connected to the inflation chamber to inject gas into the inflation chamber, thereby causing the adjusting member 34 to expand or contract by changing the volume of the injected gas, thus changing the magnitude of the damping force. This embodiment does not limit this.

[0063] The damping element 33 has a first opening 33A, which extends through the damping element 33 along the radial direction XX of the telescopic shaft 32. The adjusting element 34 can apply force to the damping element 33 so that the two opposing walls of the first opening 33A can move closer or further apart along the circumference of the telescopic shaft 32 to adjust the magnitude of the damping force.

[0064] Understandably, when the adjusting member 34 increases the force applied to the damping member 33, the two opposing walls of the first opening 33A will move closer together circumferentially along the telescopic shaft 32. At this time, the contact area between the damping member 33 and the telescopic shaft 32 increases, thereby increasing the frictional force between the damping member 33 and the telescopic shaft 32, thus increasing the damping force. The damping force is at its maximum when the two walls are in contact. Conversely, when the adjusting member 34 decreases the force applied to the damping member 33, the two opposing walls of the first opening 33A will move away circumferentially along the telescopic shaft 32. At this time, the contact area between the damping member 33 and the telescopic shaft 32 decreases, thereby decreasing the frictional force between the damping member 33 and the telescopic shaft 32, thus reducing the damping force.

[0065] In the actual vibration energy transmission process, the vibration energy generated by the barrel 20 is first transmitted to the outer shell 31, then from the outer shell 31 to the adjusting component 34, then from the adjusting component 34 to the damping component 33, and then from the damping component 33 to the telescopic shaft 32, and finally from the telescopic shaft 32 to the base 10. During this transmission process, the damping force applied by the damping component 33 to the telescopic shaft 32 will absorb and reduce the vibration energy, thereby effectively improving the vibration of the clothing processing equipment.

[0066] In this embodiment, the damping force is adjusted by applying force to the damping member 33 through the adjusting member 34, so that the vibration damping device 30 can adapt to different operating conditions of the clothing processing equipment. For example, when the clothing processing equipment is in a condition with a large amplitude, the adjusting member 34 can increase the damping force to adapt to the condition with a large amplitude. When the clothing processing equipment is in a condition with a small amplitude, the adjusting member 34 can decrease the damping force to match the condition with a small amplitude. In this way, the vibration damping device 30 of this embodiment can effectively improve the vibration and noise level of the entire clothing processing equipment under different operating conditions, thereby improving the user experience.

[0067] Furthermore, compared to the overall regular and circular structure of the damping element 33, the first opening 33A allows the damping element 33 to have a certain deformation margin in the circumferential direction of the telescopic shaft 32. When the adjusting element 34 applies force to the damping element 33, it will not be squeezed outward or excessively squeezed outward along the radial direction XX of the telescopic shaft 32. This prevents the damping element 33 from being squeezed outward locally or excessively, which would reduce the contact area between the damping element 33 and the telescopic shaft 32 and result in insufficient friction force applied by the damping element 33 to the telescopic shaft 32, thus ensuring the vibration reduction effect of the vibration damping device 30.

[0068] Please refer to the following: Figures 5-6 In some embodiments, the first opening 33A also penetrates the damping member 33 along the axial direction YY of the telescopic shaft 32. Based on the first opening 33A penetrating the damping member 33 along both the axial direction YY and the radial direction XX of the telescopic shaft 32, the damping member 33 is discontinuously arranged, i.e., disconnected. This further increases the deformation allowance of the damping member 33, thereby preventing the damping member 33 from being extruded outwards along the radial direction XX of the telescopic shaft 32.

[0069] Based on the first opening 33A penetrating the damping member 33 along the axial YY direction of the telescopic shaft 32 and the radial XX direction of the telescopic shaft 32, please refer to the following: Figures 5-6 In some structural forms, the damping element 33 includes a front end 331 and a rear end 332 arranged opposite each other in the circumferential direction along the telescopic shaft 32. The front end 331 and the rear end 332 are spaced apart in the circumferential direction of the telescopic shaft 32 to cooperate in forming a first opening 33A.

[0070] It is understandable that the damping element 33 can be made into a long strip shape with a head end 331 and a tail end 332 during the manufacturing process. Then, the damping element 33 is curled on the outer wall of the telescopic shaft 32, so that the head end 331 and the tail end 332 are opposite to each other and spaced apart in the circumferential direction of the telescopic shaft 32, so that the head end 331 and the tail end 332 cooperate to form the first opening 33A.

[0071] Please see Figure 7 In other structural forms, the damping element 33 includes at least two damping plates 333, each of which may be arc-shaped. The at least two damping plates 333 are arranged circumferentially along the telescopic shaft 32 to form a first opening 33A. For example, when there are two damping plates 333, they are arranged circumferentially along the telescopic shaft 32 and together form two first openings 33A. Alternatively, when there are at least three damping plates 333, they are arranged circumferentially along the telescopic shaft 32, and adjacent damping plates 333 form a first opening 33A. Thus, all damping plates 333 can form multiple first openings 33A.

[0072] In the structure of this embodiment, multiple damping plates 333 can be manufactured and then arranged at intervals on the outside of the telescopic shaft 32. This makes the processing simple and easy to manufacture. Furthermore, different styles of damping plates 333 can be set according to the damping force required in different areas along the circumference of the telescopic shaft 32, making the setting more flexible.

[0073] Please continue reading. Figure 7 Furthermore, along the circumference of the telescopic shaft 32, the dimensions of two adjacent first openings 33A are identical. This arrangement ensures that the deformation margins of two adjacent damping plates 333 along the circumference of the telescopic shaft 32 are roughly equal. Consequently, when the adjusting member 34 applies force to the multiple damping plates 333, the telescopic shaft 32 can be uniformly subjected to the damping force generated by the multiple damping plates 333 along its axial direction YY, preventing large vibration amplitudes in certain areas along the circumference of the telescopic shaft 32 and contributing to a more effective vibration reduction effect.

[0074] Alternatively, multiple first openings 33A can be evenly distributed along the circumference of the telescopic shaft 32. This arrangement ensures that multiple damping plates 333 are spaced apart along the circumference of the telescopic shaft 32, so that when the adjusting member 34 applies force to the multiple damping plates 333, the telescopic shaft 32 can be evenly subjected to the damping force generated by the multiple damping plates 333 along its axial direction YY, avoiding large vibration amplitude in some areas along the circumference of the telescopic shaft 32, and helping to make the vibration reduction effect more effective.

[0075] Alternatively, multiple first openings 33A can be evenly distributed along the circumference of the telescopic shaft 32, with adjacent first openings 33A having the same size. This arrangement ensures that multiple damping plates 333 are spaced apart along the circumference of the telescopic shaft 32, and that adjacent damping plates 333 have similar deformation margins along the circumference of the telescopic shaft 32. Therefore, when the adjusting member 34 applies force to the multiple damping plates 333, the telescopic shaft 32 can be evenly subjected to the damping force generated by the multiple damping plates 333 along its axial direction YY, preventing large vibration amplitudes in certain areas along the circumference of the telescopic shaft 32 and contributing to a more effective vibration reduction effect.

[0076] Please continue reading. Figure 7 In some embodiments, the adjusting member 34 is a clamp member 341, which is arranged in a ring shape and can be made of plastic. When the outer shell 31 is also made of plastic, the two can be processed by injection molding processes such as overmolding. This embodiment does not limit this.

[0077] A clamping space 30A is formed between the inner wall of the clamping member 341 and the outer wall of the telescopic shaft 32, and a damping member 33 is disposed within the clamping space 30A. The size of the clamping space 30A is adjustable. When the inner wall of the clamping member 341 approaches the outer wall of the telescopic shaft 32 radially XX, the clamping space 30A shrinks and generates a larger clamping force on the damping member 33, causing the two opposing walls of the first opening 33A to move closer together circumferentially along the telescopic shaft 32, at which point the damping force increases. Conversely, when the inner wall of the clamping member 341 moves away from the outer wall of the telescopic shaft 32 radially XX, the clamping space 30A expands and generates a smaller clamping force on the damping member 33, causing the two opposing walls of the first opening 33A to move away from each other circumferentially along the telescopic shaft 32, at which point the damping force decreases.

[0078] Thus, by setting the clamp 341, the damping force applied by the damping member 33 to the telescopic shaft 32 can be changed. The structure is simple, and the ring-shaped clamp 341 can be set to wrap around the damping member 33 in the circumference of the telescopic shaft 32, so that the vibration reduction effect is effective.

[0079] Please continue reading. Figure 7 Furthermore, the vibration damping device 30 also includes a drive assembly 35, which is mounted on the housing 31. The clamp 341 includes an annular body 3411, a first connecting portion 3412, and a second connecting portion 3413.

[0080] In this embodiment, the annular body 3411 is the main body of the clamp 341, and a clamp space 30A is formed between the inner wall of the annular body 3411 and the outer wall of the telescopic shaft 32. In this embodiment, the annular body 3411 is disconnected, and therefore has two opposite and spaced ends along its extension direction. The first connecting part 3412 is connected to one end of the annular body 3411, and the second connecting part 3413 is connected to the other end of the annular body 3411 and is spaced apart from the first connecting part 3412 to form a second opening 341A, which communicates with the clamp space 30A.

[0081] The drive assembly 35 is connected to the second connecting portion 3413 to drive the first connecting portion 3412 and the second connecting portion 3413 to move closer or further apart, thereby making the size of the clamp space 30A adjustable. Specifically, when the first connecting portion 3412 and the second connecting portion 3413 are closer together, the second opening 341A becomes smaller, which allows the annular body 3411 to contract, thereby reducing the size of the clamp space 30A; while when the first connecting portion 3412 and the second connecting portion 3413 are further apart, the second opening 341A becomes larger, which allows the annular body 3411 to expand outward, thereby increasing the size of the clamp space 30A.

[0082] Based on this, this embodiment can utilize the transmission cooperation between the drive component 35 and the second connecting part 3413 to achieve automatic adjustment of the size of the clamp space 30A. Furthermore, by using the approach or distance between the second connecting part 3413 and the first connecting part 3412, the size of the clamp space 30A changes uniformly along the circumferential direction of the telescopic shaft 32, thereby resulting in a more balanced clamping force on the damping component 33, which helps to improve the vibration reduction effect.

[0083] Please continue reading. Figure 7 In some structural forms, the second connecting part 3413 is provided with a threaded hole, that is, the inner wall of the threaded hole forms an internal thread structure. The drive assembly 35 includes a drive member 351 and a threaded rod 352, and the drive member 351 is connected to the threaded rod 352 in a transmission connection.

[0084] The drive component 351 can be a motor, electric motor, or other similar type, and this embodiment does not limit this. The outer wall of the threaded rod 352 has an external thread structure, and the threaded rod 352 passes through the first connecting part 3412 and is threadedly connected to the threaded hole of the second connecting part 3413, that is, the external thread structure and the internal thread structure are threadedly connected.

[0085] Driven by the driving member 351, the threaded rod 352 can rotate around its axis to engage with the threaded hole, thereby moving the second connecting part 3413 closer to or further away from the first connecting part 3412. For example, when the driving member 351 drives the threaded rod 352 to rotate forward, the second connecting part 3413 can move closer to the first connecting part 3412, thus reducing the clamping space 30A; while when the driving member 351 drives the threaded rod 352 to rotate in reverse, the second connecting part 3413 can move away from the first connecting part 3412, thus increasing the clamping space 30A.

[0086] It should be noted that the drive assembly 35 also includes a housing mounted on the outer casing 31, the drive member 351 is disposed inside the housing, and the threaded rod 352 passes through the housing and is connected to the drive member 351 in a transmission manner.

[0087] In this embodiment, a threaded hole is directly formed on the second connecting part 3413 to cooperate with the threaded rod 352, thereby realizing the transmission connection between the drive assembly 35 and the second connecting part 3413. This reduces the number of parts and the assembly steps of the drive assembly 35 and the clamp 341, thus improving assembly efficiency.

[0088] Please continue reading. Figure 7Furthermore, the second connecting portion 3413 includes a connecting section 3414 and an extension section 3415. The extension section 3415 is connected to the connecting section 3414 along the axial direction of the threaded rod 352, wherein the threaded hole passes through the connecting section 3414 and the extension section 3415. In this way, the extension section 3415 can be used to extend the dimension of the threaded hole along the axial direction YY of the threaded rod 352, thereby increasing the engagement area of ​​the threaded rod 352 with the threaded hole, which in turn helps to improve the firmness of the threaded connection between the threaded rod 352 and the threaded hole.

[0089] Please see Figure 8 In some other structural forms, the drive assembly 35 includes a drive element 351, a nut 353, and a threaded rod 352.

[0090] The driving component 351 can be a motor, electric motor, or other similar type. This embodiment does not limit this type. The driving component 351 is connected to the threaded rod 352 for transmission.

[0091] The nut 353 is fixedly connected to the second connecting part 3413 and is provided with a threaded hole. The inner wall of the threaded hole forms an internal thread structure. The outer wall of the threaded rod 352 forms an external thread structure, and the threaded rod 352 passes through the first connecting part 3412 and the second connecting part 3413, and is threadedly connected to the threaded hole of the nut 353, that is, the external thread structure and the internal thread structure are threadedly connected.

[0092] Driven by the driving member 351, the threaded rod 352 can rotate around its axis to engage with the threaded hole, so that the nut 353 can move the second connecting part 3413 closer to or away from the first connecting part 3412. For example, when the driving member 351 drives the threaded rod 352 to rotate forward, the second connecting part 3413 can move closer to the first connecting part 3412, thereby reducing the clamping space 30A; while when the driving member 351 drives the threaded rod 352 to rotate in reverse, the second connecting part 3413 can move away from the first connecting part 3412, thereby increasing the clamping space 30A.

[0093] In this way, a nut 353 with a threaded hole can be set separately to engage with the threaded rod 352, without the need to form a threaded hole on the second connecting part 3413, making the structure of the clamp 341 simpler and facilitating the manufacturing and production of the clamp 341.

[0094] It should be noted that the garment processing equipment also includes a main controller (not shown in the figure). The main controller is electrically connected to the drive component 351 to control the rotation speed of the drive component 351 and the direction of rotation of the drive threaded rod 352. Thus, the main controller can adaptively control the operation of the drive component 351 according to the current working conditions of the garment processing equipment to adjust the magnitude of the damping force and thus match different working conditions.

[0095] Please see Figure 9In some embodiments, along the axial direction YY of the telescopic shaft 32, the thickness of the clamp 341 is greater than or equal to the thickness of the damping member 33. This configuration improves the wrapping effect of the clamp 341 on the damping member 33, allowing the clamp 341 to apply clamping force to the damping member 33 as a whole. This results in a more uniform damping force applied by the damping member 33 to the telescopic shaft 32, making the vibration reduction effect more effective.

[0096] Please see Figure 9 In some embodiments, the housing 31 includes a main body segment 311 and a mounting segment 312. The main body segment 311 is the main part of the housing 31 and one end is used to connect to the barrel 20. The drive assembly 35 is mounted on the main body segment 311. The mounting segment 312 is connected to the other end of the main body segment 311. It is understood that the telescopic shaft 32 can pass through the mounting segment 312 and the main body segment 311 in sequence. The inner diameter of the mounting segment 312 is larger than the inner diameter of the main body segment 311, so as to form an installation space 312A at the bottom of the main body segment 311.

[0097] Both the damping element 33 and the adjusting element 34 are installed within the installation space 312A. This allows for sufficient installation space 312A for the damping element 33 and the adjusting element 34, enabling their installation within the housing 31. Furthermore, by utilizing only a section of the housing 31 for expansion, compared to increasing the overall inner diameter of the housing 31, the material used in the housing 31 can be reduced, thereby lowering the overall cost of the vibration damping assembly.

[0098] Please continue reading. Figure 9 Furthermore, the outer casing 31 also includes a limiting member 313, which can be in the form of a cover plate and is arranged in a ring shape so that the telescopic shaft 32 can pass through the limiting member 313. The limiting member 313 is disposed within the installation space 312A and is connected to the installation section 312. The limiting member 313 is located along the axial direction YY of the damping member 33 on the side of the adjusting member 34 away from the main body section 311.

[0099] Along the axial direction YY of the telescopic shaft 32, the limiting member 313 is used to block the adjusting member 34 to prevent the adjusting member 34 from falling out of the mounting section 312. In this way, the stability of the adjusting member 34 within the mounting space 312A can be improved, the probability of the adjusting member 34 falling out of the mounting space 312A of the mounting section 312 can be reduced, and the durability of the vibration damping device 30 can be improved.

[0100] Alternatively, along the axial direction YY of the telescopic shaft 32, the limiting member 313 is used to block the damping member 33 to prevent the damping member 33 from dislodging from the mounting section 312. In this way, the stability of the damping member 33 within the mounting space 312A can be improved, the probability of the damping member 33 dislodging from the mounting space 312A of the mounting section 312 can be reduced, and the durability of the vibration damping device 30 can be improved.

[0101] Alternatively, the limiting member 313 can be used to block the adjusting member 34 and the damping member 33 to prevent them from detaching from the mounting section 312. This improves the stability of the adjusting member 34 and the damping member 33 within the mounting space 312A, reduces the likelihood of them detaching from the mounting space 312A of the mounting section 312, and enhances the durability of the vibration damping device 30.
