Description

Technical Field

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

[0002] Taking a pulsator-type garment processing equipment as an example, with the external dimensions of the cabinet remaining unchanged, as the washing volume increases, the gap between the drum assembly and the cabinet becomes smaller and smaller. During the washing or spin-drying process, the drum assembly will vibrate and sway, and is prone to impacting the cabinet, affecting the safety of the garment processing equipment.

[0003] In related technologies, vibration damping devices for garment processing equipment mainly employ spring-based damping mechanisms. These devices absorb and buffer the vibration energy generated during equipment operation using elastic elements (such as coil springs and leaf springs). Their working principle is based on utilizing the elastic deformation of the spring to counteract vibration, thereby reducing the vibration amplitude of the equipment. However, the damping effect of spring-based damping devices relies heavily on the elastic characteristics of the spring, and their damping effect is very limited. When the equipment generates high-frequency vibrations during operation, the spring is prone to entering a resonance state. In this state, not only does it fail to effectively dampen vibration, but it also amplifies the vibration amplitude, leading to unstable equipment operation and increased noise. Summary of the Invention

[0005] On one hand, this application provides a vibration damping device applied to a garment processing equipment.

[0019] One end of the transmission component is rotatably connected to the first moving component and together they form a first installation space; a damping component is installed in the first installation space.

[0020] One end of the other transmission component is rotatably connected to the second moving component and together they form the second mounting space; the other damping component is installed in the second mounting space.

[0021] The other ends of the two transmission components are rotatably connected and together form a third mounting space, and the remaining damping component is installed in the third mounting space.

[0022] In some embodiments, the number of transmission components is N, the number of damping components is N+1, and N≥3; the N transmission components are sequentially rotatably connected.

[0023] One end of the transmission component located at the first end is rotatably connected to the first moving component and together they form a first installation space, and a damping component is installed in the first installation space;

[0024] One end of the transmission member located at the end is rotatably connected to the second moving member and together they form a second mounting space; the other damping member is installed in the second mounting space.

[0025] The damping element is also provided at the rotational connection between two adjacent transmission components.

[0026] On the other hand, this application also provides a garment processing device, comprising:

[0027] Box;

[0028] The cylindrical assembly is disposed within the housing;

[0029] The boom connects the housing and the cylinder assembly; and

[0030] In any of the above-described vibration damping devices, the first moving component is connected to the cylinder assembly, and the second moving component is connected to the housing or the suspension rod.

[0031] In some embodiments, the garment processing device further includes:

[0032] Mounting base, connected to the outer peripheral wall of the cylindrical assembly; and

[0033] A quick-release mechanism is connected to the first moving part and is used to fix the first moving part on the mounting base.

[0034] In some embodiments, the first moving member has a first connecting hole, and the mounting base has a second connecting hole; wherein the quick-release mechanism includes:

[0035] A fastener, passing through the first connecting hole and the second connecting hole, with a portion of the fastener exposed outside the second connecting hole; and

[0036] The limiting member is detachably connected to the mounting base and abuts against the portion of the fixing member exposed outside the second connecting hole.

[0037] In some embodiments, the mounting base is provided with a limiting groove, the bottom wall of the limiting groove has a second connecting hole, and the fixing member includes a first fixing part and a second fixing part connected together, the first fixing part and the second fixing part are arranged at an angle, the first fixing part passes through the first connecting hole and the second connecting hole, and the second fixing part is disposed in the limiting groove;

[0038] The limiting member is configured as a screw, the head of which covers part of the opening of the limiting groove to limit the second fixing part within the limiting groove.

[0039] In some embodiments, the vibration damping device includes multiple components, and the garment handling device further includes:

[0040] A connector for connecting the first moving part of one of the vibration damping devices to the second moving part of an adjacent vibration damping device.

[0041] The vibration damping device of this application embodiment, through the connection of the first moving member to the cylinder assembly and the connection of the second moving member to the housing or the boom, and the rotatable connection between the first moving member, the second moving member and at least one transmission member, enables the vibration damping device to disperse the lateral vibration force generated by the cylinder assembly through the relative rotation between the components. This structural design fully utilizes the relative motion between the first moving member, the second moving member and the transmission member to initially disperse the vibration energy of the cylinder assembly through mechanical motion, thereby weakening the propagation of vibration at its source.

[0042] This technical solution incorporates damping components at both the rotational connection points between the first moving component and the transmission component, and at the rotational connection points between the second moving component and the transmission component. These damping components generate damping forces when the components rotate relative to each other, effectively dissipating vibration energy. This damping force not only further reduces the lateral displacement of the cylinder assembly but also significantly reduces the amplitude and frequency of vibration through the energy dissipation characteristics of the damping components.

[0043] Because the lateral displacement of the cylinder assembly is effectively controlled, the possibility of the cylinder assembly colliding with the housing under high-speed rotation or other operating conditions is further reduced. This reduction in impact not only directly reduces the impact noise generated by collisions, but also indirectly reduces the friction and wear between the garment processing equipment components caused by vibration. As a result, while improving the operational stability of the garment processing equipment, the noise level of the garment processing equipment during operation is significantly reduced.

[0061] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0062] Please see Figure 1 This application provides a clothing processing device 1000, including a housing 200, a drum assembly 300, and a vibration damping device 100. The clothing processing device 1000 can be a washing machine, such as a top-loading washing machine or a front-loading washing machine. For ease of description, each embodiment of this application uses a top-loading washing machine as an example for illustration.

[0063] The cabinet 200 is generally made of sheet metal by bending. The cabinet 200 includes an internal space with an open end and a worktable covering the open end. This internal space can house other components of the washing machine, such as circuitry, air ducts, a drive mechanism, and drainage components. A detergent dispenser can be located at the front end of the worktable. The cabinet 200 can be a hollow cuboid or a hollow cylinder. The inner periphery of the cabinet 200 generally has four corners, each with a corner plate 201.

[0064] Please see Figure 1 and Figure 2The drum assembly 300 is disposed within the housing 200, and a mounting base 301 is provided at the bottom of the drum assembly 300. For a top-loading washing machine, the axial direction of the drum assembly 300 is the same as the height direction of the housing 200. For a front-loading washing machine, the axial direction of the drum assembly 300 intersects with the height direction of the housing 200. Taking a top-loading washing machine as an example, the drum assembly 300 includes an outer drum and an inner drum rotatably disposed within the outer drum. The inner drum is hollow to form a washing chamber. A through hole is provided on the peripheral wall of the inner drum, through which washing water can be discharged from the inner drum to the outer drum. A wastewater outlet is provided at the bottom of the outer drum, and washing water is discharged from the machine body through a drain assembly connected to the wastewater outlet. A loading and unloading port communicating with the washing chamber is provided at the top of the drum assembly 300, through which clothes are placed into the washing chamber for washing. A door is provided correspondingly in the housing 200 to close the loading and unloading port of the drum assembly 300 when washing clothes, so that the washing chamber is a sealed space when washing clothes. Taking a top-loading washing machine as an example, the washing machine 1000 is a type of washing machine where a motor drives a pulsator to rotate, causing the clothes to tumble up and down in the water. Driven by the pulsator, the water inside the drum assembly 300 forms alternating left- and right-handed vortices, causing the clothes to rotate and tumble, thus achieving washing and dehydration. During the washing and dehydration process, the drum assembly 300 inevitably vibrates; therefore, a vibration damping device 100 is needed to reduce the vibration displacement of the drum assembly 300.

[0065] like Figure 2 As shown, the garment processing equipment 1000 also includes a suspension rod 4 and a vibration damping sleeve 5. The suspension rod 4 is connected to the housing 200 and the drum assembly 300. Specifically, the upper end of the suspension rod 4 can be connected to the corresponding corner plate 201 of the housing 200 via a positioning element, which can be a bolt. The lower end of the suspension rod 4 is connected to the vibration damping sleeve 5, which is fixedly connected to the mounting base 301 at the bottom of the drum assembly 300. That is, one end of the suspension rod 4 is connected to the housing 200, and the other end is connected to the drum assembly 300. The vibration damping sleeve 5 contains a spring assembly 51 and a spring seat 52 for fixing the spring assembly 51. Thus, the suspension rod 4 is mainly used to buffer the vibration of the drum assembly 300 along the height direction.

[0066] In one example, only two of the four corner plates 201 of the housing 200 located diagonally are equipped with hanging rods 4. In another example, each of the four corner plates 201 of the housing 200 is equipped with the same hanging rod 4.

[0067] In the existing technology, the structure used for vibration reduction is usually the hanger 4 and the vibration damping sleeve 5 connecting the box 200 and the cylinder assembly 300. It mainly reduces the vertical displacement of the cylinder assembly 300 during operation, but lacks management of the horizontal displacement of the cylinder assembly 300 and the impact between it and the box 200. However, in actual operation, especially in the dehydration stage, the cylinder assembly 300 will generate eccentric force due to uneven load, causing it to swing significantly in the horizontal direction. If this horizontal displacement is not effectively controlled, it is easy for the cylinder assembly 300 to collide with the box 200, thereby causing problems such as increased noise and vibration or even component damage.

[0068] Therefore, this application provides a vibration damping device 100 that can control the horizontal displacement of the cylinder assembly 300 during operation.

[0069] like Figure 3 , Figure 4 and Figure 5 As shown, the vibration damping device 100 includes a first moving member 1, a second moving member 2, and a damping component 3. The end of the first moving member 1 away from the second moving member 2 is connected to the cylinder assembly 300, and the end of the second moving member 2 away from the first moving member 1 is connected to the rod 4 or the housing 200. The damping component 3 is disposed between the first moving member 1 and the second moving member 2. It should be noted that the first moving member 1, the second moving member 2, and the damping component 3 are arranged approximately along the same transverse direction so that they can act on the vibration path of the cylinder assembly 300, thereby enabling the vibration damping device 100 to absorb and dissipate the vibration force of the cylinder assembly 300 in both the transverse and longitudinal directions.

[0070] In one configuration, the end of the second moving member 2 away from the first moving member 1 is connected to the boom 4. Since the boom 4 can be used to buffer the vibration of the cylinder assembly 300 along the height direction, while the vibration damping device 100 mainly restricts the displacement of the cylinder assembly 300 in the horizontal direction, through the synergistic effect of the vibration damping device 100 and the boom 4, comprehensive vibration damping of the cylinder assembly 300 in multiple directions can be achieved, avoiding collision between the cylinder assembly 300 and the housing 200, and reducing the noise generated by the cylinder assembly 300 during operation.

[0071] In another configuration, the end of the second moving part 2 away from the first moving part 1 is connected to the housing 200. A connecting rod can be provided on the side of the housing 200 facing the tube assembly 300 to connect with the second moving part 2. The vibration damping device 100 can effectively reduce the horizontal vibration energy of the tube assembly 300 through the damping component 3 between the first moving part 1 and the second moving part 2. That is, the second moving part 2 has a flexible connection method. In some simplified clothing processing equipment 1000, the absence of the hanging rod 4 can reduce the complexity and cost of the equipment. In this case, the second moving part 2 of the vibration damping device 100 is connected to the housing 200 and can still provide the necessary vibration damping function to reduce the occurrence of collisions between the tube assembly 300 and the housing 200.

[0072] Please continue reading. Figure 3 , Figure 4 and Figure 5 The damping component 3 includes at least one transmission element 31 and at least two damping elements 32. The at least one transmission element 31 is rotatably connected to both the first moving element 1 and the second moving element 2. In one configuration, there is only one transmission element 31, with both the first moving element 1 and the second moving element 2 rotatably connected to it. This means that a single transmission element 31 is used to transmit and disperse vibration energy. In another configuration, there are two or more transmission elements 31, with one rotatably connected to the first moving element 1 and another rotatably connected to the second moving element 2. This multi-transmission-element design further optimizes the dispersion path of vibration energy. Through the synergistic effect of multiple transmission elements 31, vibration energy can be dissipated at multiple connection points, thereby more effectively reducing the vibration amplitude.

[0073] It should be noted that there are several ways to rotate the transmission component 31 with the first moving component 1 and the second moving component 2. In one configuration, the transmission component 31 can be connected to the first moving component 1 and the second moving component 2 via a rotating shaft. A damping ring is provided on the rotating shaft and clamped between the first moving component 1 and the second moving component 2. When the moving components rotate relative to the transmission component 31, the damping ring generates a damping force, which plays a role in vibration reduction and buffering. In another configuration, the transmission component 31 adopts a gear set, with the first moving component 1 and the second moving component 2 meshing with the transmission component 31 via gears. A damping component 32 is provided at the gear connection, such as a bearing or damping washer with damping characteristics installed on the gear shaft, thereby providing damping force during motion transmission. In yet another configuration, the transmission component 31 is connected to the first moving component 1 and the second moving component 2 via a hinge. A damping ring or damping washer is provided at the hinge, with the damping ring sleeved on the hinge shaft and gradually tightened by a constraint groove, thereby providing damping force when the moving components rotate relative to each other.

[0074] The transmission component 31 can also be designed with multiple rotational degrees of freedom in the first moving component 1 and the second moving component 2. The damping component 32 can be positioned at rotational connections in different directions, thereby reducing lateral vibration energy. This multi-directional damping component 32 arrangement effectively reduces both lateral and longitudinal vibration energy, further optimizing the vibration reduction effect. Examples include ball joint connections or universal joint connections, allowing for axial angle changes while transmitting power.

[0075] Through the connection between the first moving component 1 and the cylinder assembly 300, and the connection between the second moving component 2 and the housing 200, and the rotatable connection between the first moving component 1, the second moving component 2, and at least one transmission component 31, the vibration damping device 100 can disperse the vibration force generated by the cylinder assembly 300 through the relative rotation between the components. This structural design makes full use of the relative motion between the first moving component 1, the second moving component 2, and the transmission component 31 to initially disperse the vibration energy of the cylinder assembly 300 through mechanical motion, thereby weakening the propagation of vibration at its source.

[0076] At least two damping elements 32 are provided, meaning the number of damping elements 32 can be two, three, four, etc. One damping element 32 is located at the rotational connection between the first moving member 1 and the transmission member 31, and the other damping element 32 is located at the rotational connection between the second moving member 2 and the transmission member 31. The damping elements 32 provide damping force when the first moving member 1 and the second moving member 2 rotate relative to the transmission member 31, thereby effectively dissipating vibration energy. This damping force not only further reduces the lateral displacement of the cylinder assembly 300, but also significantly reduces the amplitude and frequency of vibration through the energy dissipation characteristics of the damping elements 32.

[0077] Other damping elements 32 can be stacked at the rotational connection between the first moving member 1 and the transmission member 31 or the second moving member 2 and the transmission member 31 to increase the damping force and thus dissipate vibration energy more effectively. Furthermore, the configuration of multiple damping elements 32 can reduce the impact of the failure of a single damping element 32 on the vibration damping device 100. Even if one damping element 32 fails, the other damping elements 32 can still continue to function, thereby improving the reliability and stability of the entire vibration damping device 100.

[0078] Because the circumferential displacement of the cylinder assembly 300 is effectively controlled, the possibility of the cylinder assembly 300 impacting the housing 200 under high-speed rotation or other operating conditions is reduced. This reduction in impact not only directly reduces the impact noise generated by the collision, but also indirectly reduces the friction and wear between the parts of the garment processing equipment 1000 caused by vibration. Thus, while improving the operational stability of the garment processing equipment 1000, it significantly reduces the noise level during operation.

[0079] Regarding the specific configuration of the damping component 3, it includes at least one transmission component 31 and at least two damping components 32, thus allowing for a variety of flexible arrangement methods. These configurations can be customized according to different application scenarios and requirements to fully demonstrate the versatility and adaptability of this technical solution. Further details will be provided below.

[0080] Please continue reading. Figure 3 , Figure 4 and Figure 5 In some embodiments, the number of transmission components 31 is one and the number of damping components 32 is two. By using a single transmission component 31, the structure of the damping assembly 3 is simplified, making the overall structure of the vibration damping device 100 more compact and suitable for environments with small gaps between the housing 200 and the cylinder assembly 300.

[0081] In this system, one end of the transmission component 31 rotates with the first moving component 1, together forming a first mounting space. A damping component 32 is installed within the first mounting space. The other end of the transmission component 31 is rotatably connected to the second moving component 2, together forming a second mounting space. Another damping component 32 is installed within the second mounting space. The first and second mounting spaces provide the structural basis for the installation of the damping component 32. The two damping components 32 are independently installed within their respective mounting spaces, facilitating replacement or adjustment and reducing maintenance complexity and cost. By providing damping force at two key rotation points, the vibration energy generated by the operation of the garment processing equipment 1000 can be more effectively dissipated, reducing unnecessary energy loss and improving energy efficiency.

[0082] When the cylinder assembly 300 vibrates, the vibration force is transmitted to the transmission component 31 through the first moving component 1. At the connection between the transmission component 31 and the first moving component 1, a damping component 32 is installed in the first mounting space. When the first moving component 1 rotates relative to the transmission component 31, the damping component 32 generates a damping force, converting the vibration force into heat energy or other forms of energy, thereby reducing the vibration energy. Simultaneously, at the connection between the transmission component 31 and the second moving component 2, another damping component 32 is installed in the second mounting space. When the second moving component 2 rotates relative to the transmission component 31, the damping component 32 also generates a damping force, further dissipating the vibration force. Through the synergistic effect of the two damping components 32, the vibration force is gradually weakened during transmission.

[0083] Please continue reading. Figure 3 , Figure 4 and Figure 5In some embodiments, the first moving member 1 includes a first main body 11 and a first connecting part 12 connected together. One end of the first connecting part 12 is used to connect to the cylinder assembly 300, and the other end is connected to the first main body 11. The first connecting part 12 has a length direction, and its length direction is arranged parallel to the horizontal direction. The second moving member 2 includes a second main body 21 and a second connecting part 22 connected together. One end of the second connecting part 22 is used to connect to the lifting rod 4 or the housing 200. In this embodiment, one end of the second connecting part 22 is used to connect to the lifting rod 4. The second connecting part 22 has a first through hole 22a. Part 22 is circumferentially disposed on the outer periphery of the boom 4 through the first through hole 22a. Since the first connecting part 12 and the second connecting part 22 are respectively connected to the cylinder assembly 300 and the boom 4, the first connecting part 12 and the second connecting part 22 are prone to wear under long-term high vibration, high impact or frequent friction conditions. In order to reduce wear, at least part of the first connecting part 12 and the second connecting part 22 are made of wear-resistant materials, such as high-hardness ceramic materials or alloyed wear-resistant steel, which can effectively resist the scouring and wear of particulate matter, thereby extending the service life of the first connecting part 12 and the second connecting part 22.

[0084] The other end of the second connecting part 22 is connected to the second main body part 21. The second main body part 21 is located closer to the first main body part 11 than the first connecting part 12. The two ends of the transmission member 31 are rotatably connected to the first main body part 11 and the second main body part 21, respectively. It should be noted that the two ends of the transmission member 31 can be rotatably connected to the first main body part 11 and the second main body part 21 in the same or different ways. For example, the transmission member 31 is rotatably connected to one end of the first main body part 11 by a hinge, and rotatably connected to the other end of the second main body part 21 by a rotating shaft.

[0085] In this embodiment, the first main body 11 and the second main body 21 are rotatedly connected to the transmission member 31 in the same way. Taking the first main body 11 as an example, the arrangement of the second main body 21 can be referenced to the connection method of the first main body 11. Specifically, the first main body 11 has a mounting hole 11a, and the damping assembly 3 also includes a fastener 33. The fastener 33 passes through the mounting hole 11a and is used to limit the transmission member 31 to the first main body 11, ensuring a stable connection between the transmission member 31 and the first main body 11. This limiting method can effectively prevent the transmission member 31 from shifting or loosening during operation, thereby ensuring the reliability of the entire vibration damping device 100. The fastener 33 can be made of high-strength materials, such as metal or engineering plastics, thereby enhancing the structural strength of the entire device while ensuring connection stability.

[0086] like Figure 5As shown, specifically, the fastener 33 may include a shaft portion 331 and plugs 332 disposed at both ends of the shaft portion 331. The shaft portion 331 passes through the transmission member 31 and the first main body portion 11. The design of the shaft portion 331 allows the transmission member 31 and the first main body portion 11 to rotate freely in the circumferential direction around the shaft portion 331. The plugs 332 limit the transmission member 31 and the first main body portion 11 together along the axial direction of the shaft portion 331, which can effectively prevent the transmission member 31 and the first main body portion 11 from relative displacement in the axial direction.

[0087] like Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments, the first main body 11 includes a first annular sub-part 111, a second annular sub-part 112, and a third annular sub-part 113 with successively decreasing outer diameters. The first annular sub-part 111 is connected to the first connecting part 12. The first annular sub-part 111, the second annular sub-part 112, and the third annular sub-part 113 are stacked in a stepped manner. The mounting hole 11a penetrates the first annular sub-part 111, the second annular sub-part 112, and the third annular sub-part 113. The transmission member 31 overlaps the first annular sub-part 111. 11. The transmission component 31 has a receiving groove 31a and a insertion hole 31b communicating with the receiving groove 31a. One end of the third annular sub-part 113 of the first main body 11 passes through the receiving groove 31a from bottom to top. The third annular sub-part 113 is inserted into the insertion hole 31b. Since the outer diameter of the second annular sub-part 112 is larger than that of the third annular sub-part 113, the second annular sub-part 112 abuts against the transmission component 31, which can effectively limit the axial displacement of the transmission component 31 while maintaining free circumferential rotation. The stepped design of multiple annular sub-parts provides natural guidance and positioning functions for assembly, reducing the alignment adjustment time during the assembly process.

[0088] The plug 332 at one end of the fastener 33 abuts against the side of the first annular sub-part 111 away from the second annular sub-part 112, and the plug 332 at the other end abuts against the side of the third annular sub-part 113 away from the second annular sub-part 112. The third annular sub-part 113 is inserted into the insertion hole 31b and can be roughly flush with the outer wall surface of the transmission member 31 with the insertion hole 31b, reducing the vibration of the transmission member 31 between the two plugs 332. Through the abutting action of the plugs 332, the fastener 33 not only restricts the axial displacement of the transmission member 31, but also enhances the stability of the entire structure.

[0089] The first installation space is formed between the groove wall of the receiving groove 31a of the transmission member 31 and the second annular sub-part 112. The damping member 32 is an annular structural member and is sleeved on the outer periphery of the second annular sub-part 112. When the transmission member 31 and the second annular sub-part 112 rotate relative to each other, the damping member 32 generates a damping force through the internal damping characteristics of its material (such as friction, viscosity, etc.). This damping force is opposite to the direction of relative motion and can effectively dissipate vibration energy and reduce vibration amplitude.

[0090] like Figure 7 As shown, it is understandable that the transmission member 31 and the second main body 21 can be configured similarly to the above-described configuration. The transmission member 31 has two spaced-apart receiving grooves 31a. The openings of the receiving grooves 31a can face the same direction or different directions. In one configuration, along the axial direction of the cylinder assembly 300, the opening of one receiving groove 31a can face upwards, and the opening of the other receiving groove 31a can face downwards. In another configuration, along the axial direction of the cylinder assembly 300, the openings of both receiving grooves 31a face downwards. This provides multiple installation methods and can be assembled according to specific requirements.

[0091] like Figure 8 As shown, in some embodiments, there are two transmission components 31 and three damping components 32. One end of one transmission component 31 is rotatably connected to the first moving component 1 and together they form a first installation space. One damping component 32 is installed in the first installation space. The first moving component 1 transmits the vibration force of the cylinder assembly 300 to the damping component 32. The damping component 32 between the first transmission component 31 and the first moving component 1 provides damping force in the first installation space to reduce the first-stage vibration energy.

[0092] One end of another transmission component 31 is rotatably connected to the second moving component 2, together forming a second mounting space. Another damping component 32 is installed within this second mounting space. The damping component 32 between the second transmission component 31 and the second moving component 2 provides damping force within the second mounting space, reducing the second-stage vibration energy. The other ends of the two transmission components 31 are rotatably connected, together forming a third mounting space, with the remaining damping component 32 installed within this third mounting space. The vibration force attenuates progressively along the transmission path, avoiding vibration concentration caused by insufficient damping at a single point. This design allows vibration energy to be dissipated at multiple locations, further optimizing the overall vibration reduction performance of the system.

[0093] Please continue reading. Figure 8Specifically, the two transmission components 31 are the first transmission section and the second transmission section, respectively, and the number of damping components 32 is three. Vibrational force is transmitted from the cylinder assembly 300 to the first main body section 11 of the first moving member 1 connected thereto, and then through the first main body section 11 to the first transmission section. A first damping component 32 is provided at the rotational connection between the first main body section 11 and the first transmission section. When the first main body section 11 rotates relative to the first transmission section, this damping component 32 generates a damping force, consuming part of the vibrational energy, thereby achieving the first reduction.

[0094] Subsequently, the vibrational energy, after its initial reduction, is transmitted from the first transmission unit to the second transmission unit. A second damping element 32 is provided at the rotational connection between the first and second transmission units. When the first and second transmission units rotate relative to each other, this damping element 32 provides damping force again, further reducing the vibrational energy.

[0095] Finally, the vibrational energy, after being reduced a second time, is transmitted from the second transmission unit to the second main body 21 of the second moving part 2. A third damping element 32 is provided at the rotational connection between the second transmission unit and the second main body 21. When the second transmission unit rotates relative to the second main body 21, this damping element 32 provides a third damping force, further reducing the vibrational energy. Through this multi-stage damping structure, the vibrational energy is gradually reduced during transmission, ultimately resulting in a significant reduction in the vibrational force transmitted to the boom 4 or the housing 200.

[0096] It should be noted that the connection between the first transmission part and the first main body 11 can refer to the embodiment where only one transmission member 31 is provided. The adjacent ends of two transmission members 31, i.e., the first transmission part and the second transmission part, can be rotatably connected in various ways. For example, the first transmission part has a column, and the second transmission part has a mounting groove. The column is inserted into the mounting groove, and the second damping member 32 is sleeved on the circumferential direction of the column, located between the column and the groove wall of the mounting groove. This makes the connection between the first and second transmission parts more compact and stable. Sleeving the second damping member 32 on the circumferential direction of the column, located between the column and the groove wall of the mounting groove, ensures that the damping member 32 is uniformly stressed during relative movement, thereby more effectively dissipating vibration energy. In other embodiments, the rotation of the first and second transmission parts can also be achieved by using a sliding joint (such as a sliding bearing) to connect the first and second transmission parts, while providing damping material on the sliding contact surface to dissipate vibration energy. Alternatively, the first and second transmission parts can be connected by gear meshing. A damping element 32 is provided at the gear connection, for example, a bearing or shim with damping characteristics is installed on the gear shaft, thereby providing damping force during motion transmission.

[0097] like Figure 9As shown, in some embodiments, the number of transmission components 31 is N, and the number of damping components 32 is N+1, where N≥3; the N transmission components 31 are sequentially rotatably connected; that is, the number of transmission components 31 is three or more, multiple transmission components 31 are arranged in parallel series, and adjacent transmission components 31 are rotatably connected, with damping components 32 provided at each rotatable connection. For example, each transmission component 31 has a length direction, with the first end along the length direction of the third transmission component 31 rotatably connected to the second end of the second transmission component 31, and the second end along the length direction of the third transmission component 31 rotatably connected to the first end of the fourth transmission component 31. Damping components 32 are respectively provided at the rotatable connections at both ends of the third transmission component 31, so that the vibration energy is gradually reduced when it is transmitted from one end of multiple transmission components 31 to the other end, and after multiple dissipations and abrasions, the vibration reduction effect is significantly improved.

[0098] One end of the transmission component 31 at the first end is rotatably connected to the first moving component 1 and together they form the first installation space. A damping component 32 is installed in the first installation space. The first moving component 1 is also connected to the cylinder assembly 300 and can transmit the vibration of the cylinder assembly 300 during operation. One end of the transmission component 31 at the end is rotatably connected to the second moving component 2 and together they form the second installation space. Another damping component 32 is installed in the second installation space. The second moving component 2 is also connected to the boom 4 or the housing 200. After being gradually reduced by N+1 damping components 32, the longitudinal vibration force transmitted to the housing 20 is greatly reduced.

[0099] For a specific rotational connection method between the first moving part 1 and the second moving part 2, please refer to the embodiment in which only one transmission part 31 is provided.

[0100] In this embodiment, the fastener 33 is arranged approximately parallel to the axial direction of the cylinder assembly 300 in the extension direction. That is, the first moving member 1, the transmission member 31 and the second moving member 2 all rotate around the fastener 33 in the circumferential direction, and the multiple transmission members 31 are also configured to rotate in the lateral direction. The main purpose of this design is to reduce the lateral vibration energy of the cylinder assembly 300. However, by adjusting their relative rotation direction, the longitudinal vibration energy can be reduced, thereby optimizing the overall vibration reduction effect.

[0101] By adjusting the relative rotational directions between multiple transmission components 31, between transmission component 31 and the first moving component 1, and between transmission component 31 and the second moving component 2—for example, transmission component 31 and the first moving component 1 rotate approximately longitudinally, while the other transmission component 31 and the second moving component 2 rotate approximately laterally—this multi-directional rotational design allows for the combined reduction of vibrational force energy in different directions. This design not only effectively reduces the lateral vibrational force energy of the cylinder assembly 300 but also flexibly responds to vibration input from different directions by adjusting the relative rotational directions, further optimizing the vibration reduction effect.

[0102] like Figure 4 and Figure 7 As shown, in some embodiments, a first limiting structure 114 is further provided on the circumferential outer side of the first moving member 1. Specifically, the first limiting structure 114 may be provided on the circumferential outer side of the first annular sub-part 111 and extends towards the second annular sub-part 112 along the axial direction of the fastener 33. The transmission member 31 is provided with a second limiting structure 311, which is located at the end of the transmission member 31 away from the insertion hole 31b. The second limiting structure 311 and the first limiting structure 114 cooperate with each other in a circumferential stop to limit the maximum rotation angle of the first moving member 1 relative to the transmission member 31, thereby reducing mechanical impact and wear caused by excessive rotation.

[0103] In this embodiment, when the first moving member 1 rotates to the maximum rotation angle relative to the transmission member 31, the first limiting structure 114 and the second limiting structure 311 stop each other. The first limiting structure 114 prevents the first moving member 1 from rotating in the direction of increasing the relative rotation angle, so as to control the rotation angle of the first moving member 1 relative to the transmission member 31 within a suitable range, thereby reducing the resistance of the first moving member 1 and the transmission member 31 to return to the initial state and increasing the vibration damping reliability of the vibration damping device 100.

[0104] In the initial state, the angle between the line connecting the first limiting structure 114 and the second limiting structure 311 and the center of the first annular sub-part 111 is greater than 45°, which can limit the relative position change of the first moving part 1 and the transmission part 31 to a reasonable range, so that the first moving part 1 and the transmission part 31 can adapt to the vibration position change of the cylinder assembly 300, and increase the vibration reduction reliability of the vibration damping device 100.

[0105] It is understandable that when the cylinder assembly 300 vibrates and wobbles, the first moving part 1 and the transmission part 31 rotate relative to each other under the action of vibration. When the rotational position of the first moving part 1 relative to the transmission part 31 exceeds the critical position, the resistance of the first moving part 1 and the transmission part 31 to return to the initial state increases greatly. As a result, they cannot move adaptively according to the vibration position change of the cylinder assembly 300, which leads to the inability to effectively suppress the vibration of the cylinder assembly 300 and reduces the vibration reduction reliability of the vibration damping device 100.

[0106] It should be noted that the second moving member 2 and the transmission member 31 rotatably connected to it are also provided with corresponding limiting structures to limit the maximum rotation angle of the second moving member 2 relative to the transmission member 31. Furthermore, in an embodiment where N transmission members 31 are provided, two adjacent rotatably connected transmission members 31 may also be provided with limiting structures to limit the maximum rotation angle of the two transmission members 31 relative to each other.

[0107] like Figure 10 As shown, to ensure a more uniform damping force on the cylinder assembly 300 in all directions, multiple damping devices 100 are used, evenly spaced along the circumference of the cylinder assembly 300. Each damping device 100 has a first moving part 1 connected to the cylinder assembly 300 and a second moving part 2 connected to the housing 200. Adjacent damping devices 100 are connected by connectors 600 to form a unified damping system. This design not only effectively reduces the lateral vibration energy of the cylinder assembly 300 but also flexibly responds to vibration inputs from different directions by adjusting the relative rotation direction. Furthermore, this uniformly distributed damping force effectively avoids vibration concentration caused by insufficient local damping, further optimizing the damping effect.

[0108] like Figure 11 and Figure 12 As shown, in some embodiments, the garment processing device 1000 further includes a mounting block 400 and a quick-release mechanism 500. The mounting block 400 protrudes from the outer peripheral wall of the tube assembly 300. The quick-release mechanism 500 is connected to the first moving member 1 and is used to fix the end of the first moving member 1 to the mounting block 400. The mounting block 400 provides a stable support point for the first connecting part 12. The position of the mounting block 400 lays the foundation for the lateral connection position of the first moving member 1 and the second moving member 2. The quick-release mechanism 500 can be a positioning pin, a rotating nut, or a wedge block and a locking tongue. The design of the quick-release mechanism 500 allows the first connecting part 12 to be quickly fixed to the mounting block 400 and can also be quickly disassembled when needed. This design greatly improves the maintenance efficiency of the equipment and reduces disassembly and assembly time.

[0109] To improve the connection effect of the first moving part 1, two mounting blocks 400 can be provided. The two mounting blocks 400 are spaced apart along the axial direction of the cylinder assembly 300 on the outer peripheral wall of the cylinder assembly 300. The two mounting blocks 400 are located on the upper and lower sides of one end of the first moving part 1, respectively, thereby realizing bidirectional clamping of the first moving part 1. This ensures that the first moving part 1 is effectively confined between the two mounting blocks 400, enhancing the stability and reliability of the connection.

[0110] Please continue reading. Figure 12Specifically, the first moving part 1 has a first connecting hole, and the mounting block 400 has a second connecting hole; wherein, the quick-release mechanism 500 includes a fixing member 510 and a limiting member 520, the size and shape of the first connecting hole and the second connecting hole are adapted to the fixing member 510 so that the fixing member 510 passes through the first connecting hole and the second connecting hole, and a part of the fixing member 510 is exposed outside the second connecting hole; the limiting member 520 is detachably connected to the mounting block 400 and abuts against the part of the fixing member 510 exposed outside the second connecting hole. The function of the limiting member 520 is to prevent the fixing member 510 from falling out of the second connecting hole, thereby maintaining the fixation of the first connecting part 12 and the mounting block 400.

[0111] Understandably, when it is necessary to disassemble the first connecting part 12, the limiting member 520 is removed first, and then the fixing member 510 can be easily removed from the second connecting hole, thereby separating the first connecting part 12 from the mounting block 400.

[0112] like Figure 12 and Figure 13 As shown, the mounting block 400 is provided with a limiting groove 400a. The bottom wall of the limiting groove 400a has a second connecting hole. The fixing member 510 includes a first fixing part 511 and a second fixing part 512 connected together. The first fixing part 511 and the second fixing part 512 are set at an angle. The first fixing part 511 passes through the first connecting hole and the second connecting hole. The second fixing part 512 is set in the limiting groove 400a. Since the second fixing part 512 and the first fixing part 511 are set at an angle, for example, ninety degrees, the first fixing part 511 passes through the second connecting hole in the vertical direction. The first fixing part 511 abuts against the bottom wall of the limiting groove 400a and will not pass through the second connecting hole. Furthermore, the groove wall of the limiting groove 400a, which is disposed opposite to the limiting groove, can restrict the rotation of the second fixing part 512 in the circumferential direction. The limiting member 520 is configured as a screw, and the head of the screw covers part of the groove opening of the limiting groove 400a to limit the second fixing part 512 within the limiting groove 400a. That is, the limiting groove 400a can restrict the circumferential rotation of the fixing member 510, while the screw can restrict the movement of the fixing member 510 in the vertical direction.

[0113] Understandably, when it is necessary to disassemble the first connecting part 12, simply unscrew the screw to release the second fixing part 512, and then the fixing member 510 can be easily removed from the second connecting hole, thereby separating the first connecting part 12 from the mounting block 400.
