Description

Technical Field

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

[0002] In related technologies, the washing drum of the garment processing equipment is equipped with a balance ring, and a guide rail is provided on the inner wall of the balance ring. A balancer is encapsulated inside the balance ring and can slide along the guide rail. When the washing drum rotates eccentrically, the flow balancer moves in the balance ring in the opposite direction of the eccentricity of the washing drum, thereby maintaining the eccentric balance during the dehydration stage of the garment.

[0003] However, the balancer's movement within the balance ring is not smooth, and it may even get stuck. Summary of the Invention

[0004] In view of this, the embodiments of this application aim to provide a balancing device and clothing handling equipment that improves the smoothness of the balancer's movement and reduces the probability of jamming.

[0005] This application provides a balancing device, including:

[0006] A balancing ring, wherein a ring-shaped mounting cavity is provided inside the balancing ring and a ring track is located inside the mounting cavity;

[0007] The balancer disposed in the mounting cavity includes a power mechanism and a rolling guide assembly. The power mechanism drives the balancer to move in the mounting cavity, and the rolling guide assembly rolls with the annular track along the radial direction of the balance ring.

[0008] In some implementations, the annular track is a guide rail, and the rolling guide assembly includes at least two sets of rolling elements that clamp the guide rail between them.

[0009] In some embodiments, the annular track is an annular groove that is open on one side along the axial direction, and the rolling guide assembly can be inserted into the annular groove from the open side.

[0010] In some embodiments, the number of annular grooves is at least two, the two annular grooves are arranged at an axial interval along the balance ring, and one annular groove is open on the axial side away from the other annular groove. The number of rolling guide components is at least two sets, and one set of rolling guide components is provided in each annular groove.

[0011] In some embodiments, the rolling guide assembly includes a plurality of first balls, which roll in engagement with the radial sidewall of the annular groove via each of the first balls.

[0012] In some embodiments, the rolling guide assembly includes a rotating wheel whose axis of rotation is arranged along the axial direction of the balance ring, and the rotating wheel rolls in engagement with the annular groove along its radial sidewall.

[0013] In some embodiments, the rolling guide assembly includes a plurality of second balls spaced apart from the radial sidewall of the annular groove, and the second balls rollingly engaging with the axial sidewall of the annular groove.

[0014] In some embodiments, a plurality of second balls are arranged circumferentially along the balance ring, and the number of rotating wheels is at least two, with each second ball located between the two rotating wheels.

[0015] In some embodiments, the balance ring includes a housing and a support member disposed within the housing, the space within the housing being the mounting cavity, and the annular track being disposed on the support member.

[0016] In some implementations, the balancer is suspended from the support.

[0017] In some implementations, the support member is independent of the housing but connected to the housing.

[0018] In some embodiments, the support includes a first support sleeve and a track retainer connected to each other, the track retainer protruding from the first support sleeve on the side facing the balancer, the annular track being located on the track retainer; the balancer includes a mounting base forming a receiving space, the power mechanism being disposed in the receiving space, the receiving space being open on one radial side, and the track retainer extending into the receiving space from the open portion.

[0019] In some embodiments, the mounting base includes a connecting plate and two skeleton plates, the surfaces of the two skeleton plates being opposite each other and spaced apart along the axial direction of the balance ring, the connecting plate being connected between the two skeleton plates, the connecting plate and the two skeleton plates together defining the receiving space, and the rolling guide assembly being connected to the skeleton plates and located on the side of the skeleton plates facing the receiving space.

[0020] In some embodiments, there are two rail cages, which are arranged axially spaced along the balance ring, and the power mechanism is located between the two rail cages.

[0021] In some implementations, the first support sleeve is disposed radially outside the balancer.

[0022] In some embodiments, the balancing device includes a second support sleeve and a conductive ring, the conductive ring being sleeved on the second support sleeve, the balancer including a conductive contact portion that makes slidable conductive contact with the conductive ring, the second support sleeve being independent of the housing and connected to the housing; the balancer being located between the support member and the second support sleeve along the radial direction of the balancing ring.

[0023] In some embodiments, the housing has an inner sidewall, an outer sidewall surrounding the inner sidewall circumferentially, and a bottom wall connecting the inner sidewall and the outer sidewall;

[0024] The angle between the inner sidewall and the bottom wall is 92° to 95°; and / or, the circumferential surface of the second support sleeve facing the conductive ring is perpendicular to the bottom wall.

[0025] In some embodiments, the balance ring includes a toothed ring disposed on the support member, and the power mechanism includes a rotating gear that meshes with the toothed ring.

The balancing ring is coaxially arranged with the washing drum and rotates synchronously. The control device communicates with the balancing device to control the movement of the balancing device.

[0027] The balancing device in this embodiment achieves radial positioning through a rolling guide component and an annular track, limiting the radial sway amplitude of the balancer. Since the radial engagement between the rolling guide component and the annular track is a rolling engagement, the friction at the radial contact point between the two is rolling friction, resulting in low frictional resistance and smoother movement of the balancer. In addition, it can also reduce the radial reaction force exerted by the balance ring on the power mechanism during the movement of the balancer, reducing the probability of jamming at the contact point between the power mechanism and the balance ring.

[0050] The embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but should not be used to limit the scope of this application.

[0051] In the embodiments of this application, the terms "first", "second", and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0052] Please see Figure 1 and Figure 2 This application provides a balancing device 100, which includes a balancing ring and a balancer 2 disposed within the balancing ring.

[0053] The specific application of the balancing device 100 is not limited. For example, in this embodiment of the application, the balancing device 100 is used in a clothing processing device for description.

[0054] This application provides a garment processing device, including a washing drum, a control device, and a balancing device 100 according to any embodiment of this application. The balancing ring is coaxially arranged with the washing drum and moves synchronously with it; that is, the balancing ring is centered on the rotational center line of the washing drum. The balancing ring and the washing drum can be fixedly connected by screws, clips, welding, or other means, so that the balancing ring rotates together with the washing drum.

[0055] The balancing device 100 can be located at any position along the axial direction of the washing drum. For example, it can be located at the first end along the axial direction of the washing drum, or at the second end along the axial direction of the washing drum, or at the middle position along the axial direction of the washing drum, etc.

[0056] One or more balancing devices 100 can be installed on each washing drum.

[0057] The control device communicates with the balancer 2 to control its movement within the balance ring. In other words, the movement of the balancer 2 is controllable, not random.

[0058] When the washing drum rotates at high speed, for example, at a speed greater than 150 revolutions per minute, if the load inside the washing drum becomes eccentric, the washing drum may rotate eccentrically. The control device can control the balancer 2 to move in the balance ring according to the load eccentricity of the washing drum, so as to counteract the eccentric mass of the washing drum, suppress the eccentric amplitude of the washing drum, and thus reduce the vibration of the clothes handling equipment.

[0059] It is understood that the garment processing equipment can be either a drum-type garment processing equipment or a pulsator-type garment processing equipment; there are no restrictions here.

[0060] Clothing processing equipment can be washing machines, dryers, or washer-dryer combos, etc.

[0061] Please see Figure 7 and Figure 9 The balance ring contains an annular mounting cavity 111a and an annular track located within the mounting cavity 111a. The balancer 2 moves within the mounting cavity 111a. It should be noted that the mounting cavity 111a is approximately centered on the rotation axis of the washing drum.

[0062] The balancer 2 is located in the mounting cavity 111a. (See also...) Figures 10 to 13 The balancer 2 includes a power mechanism 22 and a rolling guide assembly 23. The power mechanism 22 drives the balancer 2 to move in the mounting cavity 111a. That is, the movement of the balancer 2 is an active movement driven by the power mechanism 22, rather than a passive random movement.

[0063] The rolling guide assembly 23 rolls with the annular track along the radial direction of the balance ring.

[0064] It should be noted that the rolling guide component 23 and the annular track rolling along the balance ring in a radial manner means that the rolling guide component 23 and the annular track are in rolling contact on opposite sides along the radial direction, and the friction between them is rolling friction.

[0065] In related technologies, during the high-speed rotation of the washing drum, for example, at a speed greater than 150 revolutions per minute, the balancer is subjected to centrifugal force within the balance ring. The balancer presses radially against the radially outer wall of the mounting cavity, resulting in a large frictional force between the balancer and the radially outer wall of the mounting cavity, which makes the balancer prone to jamming.

[0066] The balancing device 100 of this application embodiment achieves radial positioning through the rolling guide component 23 and the annular track, limiting the radial sway amplitude of the balancer 2. Since the radial engagement between the rolling guide component 23 and the annular track is a rolling engagement, the friction at the radial contact point between the two is rolling friction, resulting in low frictional resistance and smoother movement of the balancer 2. In addition, it can also reduce the radial reaction force exerted by the balance ring on the power mechanism 22 during the movement of the balancer 2, reducing the probability of jamming at the contact point between the power mechanism 22 and the balance ring.

[0067] For example, please refer to Figure 7 and Figure 9 The balance ring includes a housing 11 and a support member 12 disposed within the housing 11. The space inside the housing 11 is a mounting cavity 111a, and the annular track is disposed on the support member 12. That is, the support member 12 is disposed in the mounting cavity 111a, and the support member 12 defines the annular track.

[0068] For example, please refer to Figure 1 and Figure 2 The housing 11 includes a housing body 111 and an end cap 112, with a mounting cavity 111a disposed within the housing body 111. (See also...) Figure 7 and Figure 9 The cross-sectional shape of the shell body 111 is roughly deep U-shaped. The shell body 111 is open on one side along the axial direction. The end cap 112 closes the open part of the shell body 111 so that the mounting cavity 111a becomes a closed space to prevent water from the washing drum from seeping into the mounting cavity 111a.

[0069] During the assembly process, the balancer 2 is first placed inside the shell body 111, and then the end cap 112 is assembled onto the shell body 111.

[0070] The connection method between the end cap 112 and the shell body 111 is not limited, such as welding, screw connection, snap-fit, adhesive bonding, etc. There are no restrictions here.

[0071] In some embodiments, at least a portion of the support member 12 is integrally formed with the shell body 111, for example, by integral injection molding.

[0072] In other embodiments, the support member 12 is independent of and connected to the housing 11. Specifically, the support member 12 is independent of the end cap 112, and the support member 12 is independent of and connected to the housing body 111.

[0073] It should be noted that the independence of the support member 12 and the shell 11 means that the support member 12 is manufactured and formed separately, and the shell 11 is manufactured and formed separately. During the assembly of the balance ring, the two are assembled as independent components.

[0074] It should be noted that the inner and outer diameters of the housing 11 are adapted to the size of the washing drum, and the radius of the housing 11 is relatively large. The housing 11 is a large-sized thin-walled plastic part. During the manufacturing process, due to unforeseen reasons such as precision errors, uneven shrinkage of injection molding materials, and local deformation during use, the housing 11 is prone to unexpected deformation.

[0075] In related technologies, the housing is directly injection molded into a ring track for guiding the balancer. When the housing undergoes unexpected deformation, the ring track will deform, causing the balancer to operate poorly, increasing the balancer's movement resistance, and thus increasing the energy consumption of the clothing processing equipment. When the ring track deforms significantly, it may cause the balancer to jam.

[0076] It should be noted that the aforementioned unintended deformation refers to deformation that is not part of the design and is unpredictable, such as deformation caused by factors such as heat, humidity, plastic aging, and uneven shrinkage of injection molding materials.

[0077] In the balancing device 100 of this application embodiment, the support member 12 and the housing 11 are manufactured independently. The dimensional accuracy of the support member 12 is easier to control, thus improving the accuracy and reliability of the circular track. In addition, the support member 12 is less prone to unexpected deformation than the housing 11, and the circular track can be reliably maintained in the preset position for a long time, improving the smooth operation of the balancer 2.

[0078] For example, please refer to Figure 7 and Figure 9 The shell body 111 includes an inner sidewall 1111, an outer sidewall 1112, and a bottom wall 1113. The outer sidewall 1112 surrounds the inner sidewall 1111 circumferentially, and the inner sidewall 1111 and the outer sidewall 1112 are concentrically arranged. The bottom wall 1113 connects the inner sidewall 1111 and the outer sidewall 1112. The inner sidewall 1111, the outer sidewall 1112, and the bottom wall 1113 together define the mounting cavity 111a.

[0079] For example, the shell body 111 is an integrally formed structure, that is, the inner sidewall 1111, the outer sidewall 1112 and the bottom wall 1113 are integrally formed.

[0080] For example, please refer to Figure 7 The angle β between the inner sidewall 1111 and the bottom wall 1113 is 92° to 95°. That is, the inner sidewall 1111 is inclined at 2° to 5° relative to the bottom wall 1113. The 2° to 5° angle serves as the draft angle of the inner sidewall 1111, which facilitates the demolding of the shell 11.

[0081] It should be noted that the support member 12 can be connected to the inner wall 1111 or the outer wall 1112. In some embodiments, the support member 12 is connected to the outer wall 1112, and the balancer 2 is located between the support member 12 and the inner wall 1111. In other embodiments, the support member 12 is connected to the inner wall 1111, and the balancer 2 is located between the support member 12 and the outer wall 1112.

[0082] In some embodiments, the balancer 2 is suspended from the support 12, meaning that the weight of the balancer 2 is borne by the support 12, and the balancer 2 is not in direct contact with the housing 11. This reduces the impact of deformation of the housing 11 on the movement of the balancer 2.

[0083] The specific construction of the circular track is not limited, as long as it can determine the motion trajectory of the balancer 2.

[0084] For example, in some embodiments, the annular track is a guide rail, and the rolling guide assembly 23 includes at least two sets of rolling elements. The two sets of rolling elements sandwich the guide rail between them. That is, rolling elements are provided on both opposite sides of the guide rail in the radial direction. The balancer 2 is positioned in both directions in the radial direction by the rolling cooperation of the two sets of rolling elements and the guide rail.

[0085] In other embodiments, please refer to Figure 7 , Figure 9 as well as Figure 18 The annular track is an annular groove 122a, and the rolling guide assembly 23 is located in the annular groove 122a. The annular groove 122a is open on one side along the axial direction, allowing the rolling guide assembly 23 to be inserted into the annular groove 122a through the open portion. In this embodiment, the opposite side walls 122b of the annular groove 122a along the radial direction provide radial restraint for the rolling guide assembly 23, while the open portion along the axial direction facilitates the assembly of the rolling guide assembly 23 into the annular groove 122a. Furthermore, the annular groove 122a protects the rolling guide assembly 23, preventing it from interfering with other structures and improving the operational reliability of the rolling guide assembly 23.

[0086] It should be noted that the radial dimension of the annular groove 122a is matched with the radial dimension of the rolling guide component 23, that is, the rolling guide component 23 and the annular groove 122a are in clearance fit. The radial dimension of the annular groove 122a is slightly larger than the radial dimension of the rolling guide component 23. On the one hand, the rolling guide component 23 can roll in the annular groove 122a. On the other hand, it also minimizes the radial movement clearance of the rolling guide component 23.

[0087] The number of annular grooves 122a can be one or more.

[0088] It should be noted that in the embodiments of this application, "multiple" refers to two or more.

[0089] For example, please refer to Figure 7 , Figure 9 as well as Figure 18 There are two annular grooves 122a, which are arranged at an axial interval along the balance ring. The axial side of either annular groove 122a facing away from the other annular groove 122a is open. There are two sets of rolling guide components 23, with one set of rolling guide components 23 corresponding to each annular groove 122a.

[0090] In this embodiment, the sidewall 122c of the two annular grooves 122a facing away from the open side (refer to...) Figure 18 It is sandwiched between two sets of rolling guide components 23, which provides bidirectional positioning of the balancer 2 along the axial direction and reduces the possibility of the balancer 2 moving along the axial direction.

[0091] The specific structure of the rolling guide component 23 is not limited, as long as it can roll and rub against the radial sidewall 122b of the annular groove 122a.

[0092] In some embodiments, for example, the rolling guide assembly 23 includes a plurality of first balls, which roll in contact with the radial sidewall 122c of the annular groove 122a via the first balls. In this embodiment, it is not limited that each first ball simultaneously rolls in contact with both radial sidewalls 122b of the annular groove 122a. It is sufficient that the rolling guide assembly 23 maintains rolling friction with the radial sidewalls 122b of the annular groove 122a during contact.

[0093] In other embodiments, please refer to Figures 10 to 13 The rolling guide assembly 23 includes a rotating wheel 231, the rotation axis of which is arranged along the axial direction of the balance ring. (See also...) Figure 7 The rotating wheel 231 rolls into contact with the radial sidewall 122b of the annular groove 122a. In this embodiment, the rotating wheel 231 is generally flat and has a relatively large radial dimension and a relatively small axial dimension, which facilitates better radial guidance and does not occupy too much space axially, making the balancer 2 structure compact.

[0094] It is understandable that the number of rotating wheels 231 can be one or more.

[0095] For example, in an embodiment where there are two annular grooves 122a, there are at least four rotating wheels 231. The balancer 2 arranges at least two rotating wheels 231 in each annular groove 122a. The two rotating wheels 231 corresponding to the same annular groove 122a are spaced as far apart as possible to improve the guiding stability of the balancer 2.

[0096] In some embodiments, please refer to Figure 9 , Figure 10 , Figure 12 , Figure 13 The rolling guide assembly 23 also includes a plurality of second balls 232. The second balls 232 are spaced apart from the radially opposite side walls 122b of the annular groove 122a. That is, the second balls 232 maintain a large distance from the radially opposite side walls 122b of the annular groove 122a, and the second balls 232 never contact the radially opposite side walls 122b. The second balls 232 roll in contact with the axially opposite side walls 122c of the annular groove 122a. The second balls 232 can reduce the frictional resistance between the rolling guide assembly 23 and the axially opposite side walls 122c of the annular groove 122a, reduce the motion resistance of the balancer 2, and improve the smoothness of the balancer 2's movement along the annular groove 122a.

[0097] In some embodiments, please refer to Figure 10 , Figure 12 as well as Figure 13 Multiple second balls 232 are arranged circumferentially along the balance ring. The balancer 2 is equipped with at least two rotating wheels 231 corresponding to each annular groove 122a, and each second ball 232 is located between two rotating wheels 231. The relatively large distance between the two rotating wheels 231 along the circumferential direction of the balance ring allows the balancer 2 to have a good guiding effect on both the front and rear sides along the direction of movement; it also allows the space between the two rotating wheels 231 to be used to arrange the second balls 232.

[0098] The specific structural form of the support component 12 is not limited.

[0099] For example, please refer to Figure 18 The support member 12 includes a first support sleeve 121 and a track retainer 122 connected to each other. The first support sleeve 121 is located on one radial side of the balancer 2. The track retainer 122 protrudes from the first support sleeve 121 on the side facing the balancer 2, and an annular track is located on the track retainer 122.

[0100] Please see Figures 10 to 13 The balancer 2 includes a mounting base 21, please refer to [link / reference]. Figure 7 and Figure 9The mounting base 21 forms a receiving space 21a, which is open on one radial side. The rail retainer 122 extends into the receiving space 21a from the open portion. The first support sleeve 121 is located outside the receiving space 21a. That is, the first support sleeve 121 substantially covers the open portion of the receiving space 21a, and the first support sleeve 121 and the mounting base 21 substantially enclose a relatively closed area, which is beneficial for arranging the components of the balancer 2 in the receiving space 21a.

[0101] For example, during the assembly process, the balancer 2 and the support 12 can be assembled into a pre-assembled whole. The components of the balancer 2 are basically arranged in the accommodating space 21a. This facilitates the handling and assembly of the pre-assembled whole, and can prevent other parts from scratching the components inside the balancer 2 during handling and assembly, thus avoiding damage or loss of the components.

[0102] It should be noted that the first support sleeve 121 can be connected to the inner sidewall 1111 or the outer sidewall 1112. For example, in the embodiment where the first support sleeve 121 is connected to the inner sidewall 1111, the balancer 2 is located radially outside the first support sleeve 121.

[0103] In the embodiment where the first support sleeve 121 is connected to the outer side wall 1112, the balancer 2 is located radially inside the first support sleeve 121.

[0104] In some embodiments, the track retainer 122 is integrally formed with the first support sleeve 121, for example, by injection molding.

[0105] In other embodiments, the track retainer 122 and the first support sleeve 121 are separate structures connected together. This facilitates the separate injection molding of the track retainer 122 and the first support sleeve 121, reduces mold complexity, lowers production costs, and also helps control the manufacturing precision of the track retainer 122 and the first support sleeve 121.

[0106] In embodiments where the track retainer 122 and the first support sleeve 121 are separate structures, the track retainer 122 and the first support sleeve 121 are detachably connected. For example, please refer to... Figure 15 The first support sleeve 121 is provided with multiple pairs of slots 121a, and the track retainer 122 is provided with a snap-fit ​​structure that snaps into the slots 121a.

[0107] For example, please see Figure 15 One of the pair of slots 121a is a notch extending through to the edge of the first support sleeve 121 on one axial side, and the other is a through hole. (See also...) Figure 14The circumferential surface of the track retainer 122 is provided with a plurality of positioning hooks 1221 and a plurality of first elastic hooks 1222. The positioning hooks 1221 and the first elastic hooks 1222 are arranged at intervals along the axial direction. The positioning hooks 1221 are inserted into the notch from one axial side of the first support sleeve 121, and the first elastic hooks 1222 are inserted into the through hole. The part of the first support sleeve 121 located between the notch and the through hole is clamped between the positioning hooks 1221 and the first elastic hooks 1222, thereby realizing the rapid assembly of the first support sleeve 121 and the track retainer 122.

[0108] The specific structure of the track cage 122 is not limited. For example, please refer to [link to relevant documentation]. Figure 18 The track retainer 122 includes a first enclosure plate 1223, a second enclosure plate 1225, and a base plate 1224 connecting the first enclosure plate 1223 and the second enclosure plate 1225. The first enclosure plate 1223 and the second enclosure plate 1225 are generally cylindrical and concentrically arranged, with the first enclosure plate 1223 surrounding the second enclosure plate 1225 circumferentially. The first enclosure plate 1223, the second enclosure plate 1225, and the base plate 1224 together define a generally U-shaped annular groove 122a.

[0109] The first enclosure plate 1223 is attached to the circumferential surface of the first support sleeve 121, and the two have a large contact area, which improves the connection reliability between the track retainer 122 and the first support sleeve 121.

[0110] In an embodiment where there are two track cages 122, the two track cages 122 are arranged approximately symmetrically.

[0111] The specific structure of the mounting base 21 is not limited. For example, please refer to [link to example]. Figure 7 , Figure 9 , Figures 10 to 13 The mounting base 21 includes two frame plates 211 and a connecting plate 212 connecting the two frame plates 211. The surfaces of the two frame plates 211 are opposite each other and spaced apart along the axial direction of the balance ring, that is, the surfaces of the two frame plates 211 are approximately perpendicular to the axial direction of the balance ring. The connecting plate 212 connects the two frame plates 211.

[0112] The connecting plate 212 and the two frame plates 211 define the receiving space 21a, and the power mechanism 22 is disposed in the receiving space 21a. The rolling guide assembly 23 is connected to the frame plate 211 and is located on the side of the frame plate 211 facing the receiving space 21a. The frame plate 211 provides good axial support for the rolling guide assembly 23. Specifically, when the balancer 2 is subjected to an axial impact, the support member 12 applies a reaction force to the rolling guide assembly 23 and transmits it to the frame plate 211. The frame plate 211 can withstand the reaction force well. In addition, the structure of the mounting base 21 has good rigidity, so that the mounting base 21 can be reliably suspended on the support member 12.

[0113] In this embodiment, the structural form of the skeleton plate 211 and the connecting plate 212 enables the mounting base 21 to have elastic deformation along the axial direction, which facilitates assembly. Specifically, during the assembly process, the rolling guide component 23 on one skeleton plate 211 can be inserted into the annular groove 122a through the opening. Then, the other skeleton plate 211 can be bent axially to increase the size of the opening of the accommodating space 21a until the rolling guide component 23 on the other skeleton plate 211 is also inserted into the annular groove 122a through the opening of the corresponding annular groove 122a. At this time, the two sets of rolling guide components 23 are restricted by the two skeleton plates 211 in the corresponding annular grooves 122a. In this way, the displacement of the rolling guide components 23 along both the radial and axial sides is effectively restricted.

[0114] The specific structural form of the power mechanism 22 is not limited. Exemplarily, the power mechanism 22 includes a rotating gear 221 and a power source for driving the rotating gear 221 to rotate, such as an electric motor; see [link to relevant documentation]. Figure 1 , Figure 7 , Figure 9 as well as Figure 18 The balance ring includes a toothed ring 14, a rotating gear 221 meshing with the toothed ring 14, and a power source driving the rotating gear 221 to rotate under the control of the control device. Through the meshing of the rotating gear 221 and the toothed ring 14, the balancer 2 can be driven to move actively in the balance ring.

[0115] The gear ring 14 can be located on the radial inner side of the balancer 2 or on the radial outer side of the balancer 2, as long as it is convenient to mesh with the rotating gear 221.

[0116] In this embodiment, for example, the toothed ring 14 is disposed on the support member 12, specifically on the first support sleeve 121 of the support member 12. This facilitates control over the manufacturing precision of the toothed ring 14; regardless of whether the housing 11 undergoes unexpected deformation, the assembly of the toothed ring 14 is not affected; furthermore, since the support member 12 is less prone to unexpected deformation than the housing 11, the toothed ring 14 can be reliably maintained in a preset position for a long time, improving the meshing reliability of the toothed ring 14 and the rotating gear 221, enhancing the smoothness of the balancer 2's movement, and reducing the probability of the balancer 2 jamming.

[0117] For example, in an embodiment where there are two rail retainers 122, the power mechanism 22 is located between the two rail retainers 122. This makes full use of the space between the two rail retainers 122, improving space utilization and making the balancing device 100 structure more compact. It is understood that in this embodiment, the toothed ring 14 is also located between the two rail retainers 122.

[0118] The toothed ring 14 and the first support sleeve 121 can be a separate structure or an integral injection molded structure.

[0119] Understandably, please refer to Figure 1 , Figure 7 and Figure 9 The balancer 2 is equipped with multiple conductive rings 13. The conductive rings 13 provide the power required for the balancer 2's electrical and communication functions. For details, please refer to... Figures 10 to 13 The balancer 2 is equipped with multiple conductive contacts 24, which slide and make conductive contact with the conductive ring 13. The balancer 2 obtains power from at least one conductive ring 13 to obtain the electrical energy required for movement. The balancer 2 communicates with the control device from another conductive ring 13.

[0120] It is understandable that the number of conductive rings 13 used for power supply can be one, two, or more. When one of the conductive rings 13 is damaged, the remaining conductive rings 13 can continue to supply power to the balancer 2, thereby improving the power supply reliability of the balancer ring.

[0121] The number of conductive rings 13 used for communication can be one, two, or more. When one conductive ring 13 fails, the remaining conductive rings 13 can continue to communicate with the balancer 2, improving the communication reliability of the balancer ring.

[0122] For example, please refer to Figure 7 and Figure 9 The conductive ring 13 is provided with a conductive groove 13a, which is open to the side facing the balancer 2. The conductive contact part 24 of the balancer 2 is constructed as a brush structure, which extends into the conductive groove 13a. In this way, the brush structure and the conductive ring 13 can maintain good conductive contact.

[0123] For example, please refer to Figure 1 , Figure 7 as well as Figure 9 The balancing device 100 includes a second support sleeve 18, which is independent of and connected to the housing 11. Each conductive ring 13 is sleeved on the second support sleeve 18 and is insulated and spaced apart along the axial direction of the second support sleeve 18. Each conductive ring 13 is held in the mounting cavity 111a by the second support sleeve 18. That is, each conductive ring 13 is not directly mounted on the housing 11, but is mounted on the second support sleeve 18 and assembled onto the housing 11 by the second support sleeve 18.

[0124] During the assembly process, each conductive ring 13 and the second support sleeve 18 can be pre-assembled into a whole, and then the whole can be assembled onto the housing 11. During the assembly process, the assembly of the conductive ring 13 will not be affected regardless of whether the housing 11 undergoes unexpected deformation. In addition, since the second support sleeve 18 and the housing 11 are manufactured independently, the dimensional accuracy of the second support sleeve 18 is easier to control, making the fixed position of the conductive ring 13 on the second support sleeve 18 more reliable and improving the reliability of the conductive contact between the conductive ring 13 and the balancer 2.

[0125] It should be noted that, along the radial direction of the balance ring, the balancer 2 is located between the support member 12 and the second support sleeve 18. This facilitates the arrangement of the conductive ring 13 and the toothed ring 14 on opposite radial sides of the balancer 2, increases the arrangement space of the toothed ring 14, and allows for flexible arrangement of the power mechanism 22.

[0126] For example, please refer to Figure 7 and Figure 9 The circumferential surface of the second support sleeve 18 facing the conductive ring 13 is perpendicular to the bottom wall 1113. This ensures that the dimensions of each guide ring 13 are substantially the same, and the inner diameter of each guide ring 13 is equal, which facilitates the reliable assembly of each conductive ring 13 onto the second support sleeve 18.

[0127] In this embodiment of the application, the second support sleeve 18 is connected to the inner sidewall 1111 as an example for description.

[0128] The connection method between the second support sleeve 18 and the inner side wall 11111 is not limited.

[0129] For example, the inner sidewall 1111 is provided with a plurality of second elastic hooks on the side facing the second support sleeve 18, and the plurality of second elastic hooks are arranged circumferentially along the inner sidewall 1111. The inner surface of the second support sleeve 18 is provided with a plurality of snap-fit ​​protrusions along the radial direction, and the second elastic hooks snap onto the side of the snap-fit ​​protrusions facing away from the bottom wall 1113.

[0130] During assembly, as the second support sleeve 18 is fitted onto the inner sidewall 1111 from the side near the end cap 112, the locking protrusion forces the second elastic hook to elastically deform towards the inner sidewall 1111. Once the locking protrusion has passed the second elastic hook, the second elastic hook, under its own elastic force, returns to its elastic deformation and abuts against the surface of the locking protrusion. Thus, the locking protrusion is restricted by the second elastic hook, preventing the second support sleeve 18 from being removed from the inner sidewall 1111. This allows for rapid assembly of the second support sleeve 18 and the inner sidewall 1111 without the need for specialized tools.

[0131] For example, please refer to Figure 7The inner sidewall 1111 has a insertion groove 1111a at one end near the end cap 112, and the insertion groove 1111a is open towards the end cap 112. The second support sleeve 18 has a bent insertion rib 181 at one end near the end cap 112, and the insertion rib 181 is inserted into the insertion groove 1111a from the open part of the insertion groove 1111a. The cooperation between the insertion rib 181 and the insertion groove 1111a provides better radial restraint for the second support sleeve 18, reducing the possibility of the second support sleeve 18 swinging radially.

[0132] For example, please refer to Figure 4 and Figure 19 The balancing ring includes a magnetic element 16, which is disposed on the second support sleeve 18. It is understood that a Hall sensor is provided on the balancer 2. When the balancer 2 moves to a position where the Hall sensor and the magnetic element 16 are opposite each other, the Hall sensor outputs a pulse signal due to the magnetic field generated by the magnetic element 16. Based on this pulse signal, the balancer 2 can determine its current position corresponding to the magnetic element 16.

[0133] The magnetic component 16 and the Hall sensor work together to correct the position of the balancer 2. For example, after the balancer 2 has been moved for a long time, cumulative displacement errors may occur. Therefore, the position error of the balancer 2 can be eliminated by using the magnetic component 16 and the Hall sensor. For example, at regular intervals, the balancer 2 is driven to a position opposite to the magnetic component 16, and this position is defined as the initial position. In this way, the displacement of the balancer 2 can be corrected.

[0134] For example, please refer to Figure 4 and Figure 19 The balancing ring 1 includes a magnetic element 16, which is disposed on the second support sleeve 18. It is understood that a Hall sensor is provided on the balancer 2. When the balancer 2 moves to a position where the Hall sensor and the magnetic element 16 are opposite each other, the Hall sensor outputs a pulse signal due to the magnetic field generated by the magnetic element 16. Based on this pulse signal, the balancer 2 can determine its current position corresponding to the magnetic element 16.

[0135] The magnetic component 16 and the Hall sensor work together to correct the position of the balancer 2. For example, after the balancer 2 has been moved for a long time, cumulative displacement errors may occur. Therefore, the position error of the balancer 2 can be eliminated by using the magnetic component 16 and the Hall sensor. For example, at regular intervals, the balancer 2 is driven to a position opposite to the magnetic component 16, and this position is defined as the initial position. In this way, the displacement of the balancer 2 can be corrected.

[0136] For example, please refer to Figure 4 as well as Figure 19The balance ring 1 includes a mounting block 17, which has a receiving chamber 17a. The magnetic component 16 is disposed within the receiving chamber 17a. Thus, it is only necessary to place the magnetic component 16 within the receiving chamber 17a; no other connection method is required. For example, if the size of the receiving chamber 17a is smaller than that of the magnetic component 16, the magnetic component 16 can be held within the receiving chamber 17a by the frictional force between the two components after it is inserted into the receiving chamber 17a.

[0137] Of course, other limiting structures can also be set to limit the magnetic component 16.

[0138] Please see Figure 4 The second support sleeve 18 is provided with an assembly port 18a, through which the mounting block 17 passes. The magnetic component 16 is located on the side of the second support sleeve 18 facing the conductive ring 13. The assembly port 18a limits the mounting block 17 in the axial and circumferential directions of the support sleeve 12.

[0139] For example, please refer to Figure 19 The mounting block 17 includes an insertion portion 171 and a flange portion 172 disposed at one radial end of the insertion portion 171 along the second support sleeve 18. The insertion portion 171 passes through the assembly opening 12b, and the receiving chamber 17a is located on the insertion portion 171. The flange portion 172 is sandwiched between the side of the second support sleeve 18 away from the conductive ring 13 and the corresponding housing 11. For example, in an embodiment where the second support sleeve 18 is connected to the inner sidewall 1111, the flange portion 172 is sandwiched between the second support sleeve 18 and the inner sidewall 1111.

[0140] During the assembly process, the magnetic component 16 is placed into the receiving chamber 17a, and the mounting block 17 is passed through the assembly opening 12b from the radial inner side to the radial outer side of the second support sleeve 18 until the flange portion 172 abuts against the second support sleeve 18. Then, the second support sleeve 18 is fitted onto the inner wall 1111.

[0141] For example, the number of balancers 2 is two or more, and the number of mounting blocks 17 is multiple, with the number of mounting blocks 17 not less than the number of balancers 2.

[0142] For example, a plurality of mounting blocks 17 are arranged at circumferential intervals along the second support sleeve 18, and the number of magnetic elements 16 configured in each mounting block 17 is different from that in any other mounting block 17.

[0143] For example, one mounting block 17 may have two magnetic elements 16 configured in it, while the other mounting block 17 may have one magnetic element 16 configured in it.

[0144] The number of magnetic components 16 configured in the mounting block 17 varies, resulting in different magnetic fields. In other words, each mounting block 17 corresponds to a different magnetic field, which facilitates the positioning of each balancer 2 and prevents misalignment. Specifically, each balancer 2 corresponds to the magnetic field of a specific mounting block 17. When the position of each balancer 2 needs to be corrected, during its movement, when the balancer 2 passes its corresponding mounting block 17, it can detect the unique and distinct magnetic field, thus stopping the balancer 2 at that position.
