Description

Technical Field

[0001] The present invention relates to the field of clutches, and in particular to a clutch, a clutch transmission system and a clothing processing device. Background Art

[0002] The existing clothes processing equipment is provided with a clutch, and the clutch fork adopts an integrated double-pawl form. When the double-pawl fork is disengaged from the ratchet, the fork needs to move a large motion stroke, which is not conducive to the compact design of product components and easily causes interference between components, affecting the use effect. Summary of the invention

[0003] In order to solve at least one of the above technical problems, an object of the present invention is to provide a clutch.

[0004] Another object of the present invention is to provide a clutch transmission system having the above clutch.

[0005] Another object of the present invention is to provide a clothes processing device having the above-mentioned clutch transmission system.

[0006] To achieve the above-mentioned purpose, an embodiment of the first aspect of the present invention provides a clutch, comprising: a first shift fork and a first ratchet, the first shift fork being provided with a first pawl, and the first shift fork being configured to drive the first pawl so that the first pawl engages with or separates from the first ratchet; a second shift fork and a second ratchet, the second shift fork being provided with a second pawl, and the second shift fork being configured to drive the second pawl so that the second pawl engages with or separates from the second ratchet.

[0007] The clutch provided in the above embodiment of the present invention is provided with a first fork and a second fork to drive the first pawl and the second pawl respectively, so that the meshing and separation actions of the first pawl and the first ratchet wheel and the meshing and separation actions of the second pawl and the second ratchet wheel will not interfere with each other. In this way, the first fork and the second fork can realize the drive control of the first pawl and the second pawl with a smaller movement stroke. Compared with the integrated double-pawl structure in which one fork is provided with two pawls, the movement stroke of the fork (the first fork and the second fork) is greatly reduced, thereby correspondingly reducing the amount of space reserved for meeting the fork stroke requirements, which is more conducive to the compact design of the product and saves more product volume space. Moreover, since the stroke of the fork (the first fork and the second fork) is reduced, the risk of interference between the fork and surrounding components is reduced, which is more conducive to ensuring the operational reliability of the product.

[0008] In addition, the clutch in the above embodiment provided by the present invention may also have the following additional technical features:

[0009] In the above technical solution, the second fork includes a linkage mechanism, which is transmitted between the first fork / first pawl and the second pawl, and when the first fork drives the first pawl to move to a position separated from the first ratchet, the first fork / first pawl triggers the linkage mechanism to link with the second pawl, so that the second pawl moves to a position separated from the second ratchet.

[0010] In the present scheme, a linkage mechanism is provided to transmit between the first fork (or the first pawl) and the second pawl to establish a linkage relationship between the first fork (or the first pawl) and the second pawl, so that when the first fork controls the first pawl to loosen the first ratchet, the second pawl and the second ratchet are automatically controlled to loosen through the linkage action control of the linkage mechanism. In this way, in the double fork design of the present scheme, for the fork added compared to the related single fork technology, there is no need to separately add an external driving source to drive and control the added fork, which reduces the modification cost of the product and simplifies the structure of the product. At the same time, it is also more conducive to ensuring the consistency of the separation of the first pawl from the first ratchet and the separation of the second pawl from the second ratchet, thereby improving the accuracy of the clamping control of the wrap spring.

[0011] In any of the above technical solutions, when the first fork drives the first pawl to move to a position meshing with the first ratchet, the first fork / first pawl triggers the linkage mechanism to link the second pawl, causing the second pawl to move to a position meshing with the second ratchet.

[0012] In the present scheme, a linkage mechanism is utilized to establish a linkage relationship between the first fork (or the first pawl) and the second pawl, so that when the first fork controls the first pawl to engage with the first ratchet, the second pawl is automatically controlled to engage with the second ratchet through the linkage control of the linkage mechanism. Thus, in the double fork design of the present scheme, compared with the related single fork technology, there is no need to separately add an external driving source to drive and control the added fork, thereby reducing the modification cost of the product and simplifying the structure of the product. At the same time, it is also more conducive to ensuring the consistency of the engagement of the first pawl with the first ratchet and the engagement of the second pawl with the second ratchet, thereby improving the accuracy of the spring release control.

[0013] In any of the above technical solutions, the linkage mechanism includes: a slider, on which a first meshing portion is provided; a movable member, on which a second meshing portion is provided and the second meshing portion is meshed with the first meshing portion for transmission, the second pawl is arranged on the movable member, the first fork / first pawl abuts against the slider and drives the slider to slide, so that the slider drives the second pawl to move toward a position meshing with the second ratchet wheel via the movable member.

[0014] In the present solution, the slider and the movable part are arranged to mesh with each other via the first meshing part and the second meshing part to transmit the power between the first fork (first pawl) and the second pawl. The meshing transmission has the advantages of good transmission stability and high transmission accuracy, which can help improve the movement accuracy of the second pawl and the consistency of the movement with the first pawl, and improve the accuracy of the spring release control. The meshing transmission has a compact layout and can further save product space.

[0015] In any of the above technical solutions, the second meshing portion includes gear teeth, and the gear teeth are arranged along the outer periphery of the movable part, the first meshing portion includes a rack, and the rack is distributed on the circumference of the movable part and is arc-shaped, the second pawl protrudes from the movable part to the side of the movable part, and the rotation of the movable part drives the second pawl to rotate.

[0016] In the present embodiment, the second meshing portion and the first meshing portion are arranged to form a meshing of gear teeth and an arc-shaped rack, so that the movable part can be driven to rotate when the slider slides, wherein the second pawl protrudes toward the side of the movable part, so that the second pawl swings when the movable part rotates. The transmission chain has high transmission accuracy, compact structure, and small size, and the second pawl engages or separates with the second ratchet wheel by swinging, and the required stroke is small, and the movement space required for the activity is small, which is more conducive to compact product layout, and can effectively avoid the problem of interference between the second pawl and other components, thereby ensuring the reliability of the product.

[0017] In any of the above technical solutions, the second shift fork also includes a fixed block, and the movable part and the slider are arranged on the fixed block, wherein the fixed block and the slider are slidably matched, and a guide structure is provided on the fixed block, and the guide structure cooperates with the slider and guides the slider.

[0018] In this solution, a fixed block is set, and the movable part and the slider are set on the fixed block. In this way, the movable part and the slider are set on the same basis, and the transmission matching accuracy between the movable part and the slider can be higher, further improving the control accuracy of the first fork (or the first pawl) on the second pawl.

[0019] A guide structure is provided on the fixed block to guide the sliding of the slider, which can prevent the slider from moving out of position and ensure the smooth sliding of the slider, thereby further improving the control accuracy of the first fork (or the first pawl) on the second pawl.

[0020] In any of the above technical solutions, the guide structure includes a guide groove and a slide rail formed on the fixed block, the slider is mounted on the slide rail, and the slider is provided with a convex edge, which extends into the guide groove and slides along the guide groove.

[0021] In this solution, the guide structure includes a slide rail and a guide groove, and the slider is mounted on the slide rail, so that the slider slides along the slide rail to achieve a good guiding and limiting effect, making the sliding of the slider more precise and smooth, thereby improving the transmission accuracy of the slider between the first fork (or the first ratchet) and the second ratchet, thereby further improving the control accuracy of the first fork (or the first ratchet) over the second ratchet.

[0022] In any of the above technical solutions, the linkage mechanism includes: a first elastic member connected to the second pawl, wherein the second pawl compresses the first elastic member when it is in engagement with the second ratchet, and the first elastic member elastically recovers to drive the second pawl to separate from the second ratchet.

[0023] In the present solution, a first elastic member is provided to be connected to the second pawl. When the first fork (or the first pawl) drives the second pawl to engage with the second ratchet, the second pawl presses against the first elastic member to compress the first elastic member to store energy. When the first fork (or the first pawl) releases the second pawl, the elastic restoring force of the first elastic member drives the second pawl to separate from the second ratchet, thereby realizing the linkage action between the first fork (or the first pawl) and the second pawl. The solution has the advantages of simple structure, precise control and easy assembly.

[0024] In any of the above technical solutions, the clutch also includes a stop portion, wherein when the second pawl moves to a position separated from the second ratchet, the stop portion stops and abuts against any one of the slider, the movable part and the second pawl to limit the second pawl from continuing to move.

[0025] In the present solution, the stop portion is utilized to stop and abut against any one of the slider, the movable part and the second pawl to limit the second pawl from continuing to move after being separated from the first ratchet. On the one hand, while achieving the regulation requirements of the second pawl engaging and separating with the second ratchet, the stroke of the second pawl can be effectively limited, which can increase the control accuracy of the second pawl and prevent control demand problems and interference risk problems caused by excessive stroke of the second pawl. On the other hand, the first elastic member is utilized to push the second pawl against the stop portion, so that the second pawl can remain stable in the position separated from the second ratchet to prevent loosening problems.

[0026] In any of the above technical solutions, the first shift fork includes: a shift rod connected to the first pawl and driving the first pawl to make the first pawl engage with or separate from the first ratchet wheel; a second elastic member connected to the shift rod / first pawl, so that the first pawl is in a position separated from the first ratchet wheel so that the shift rod / first pawl compresses the second elastic member, and the second elastic member elastically recovers so that the first pawl engages with the first ratchet wheel.

[0027] In the present solution, a first shift fork is provided including a shift rod and a second elastic member. An external driving source (such as an electromagnet, a motor, a traction device, etc.) drives the shift rod, so that when the shift rod controls the first pawl to separate from the first ratchet, the shift rod / first pawl is used to compress the second elastic member, so that the second elastic member is compressed and stores energy. When the driving force of the external driving source is removed, the elastic restoring force of the second elastic member is used to drive the shift rod / first pawl, which can realize automatic resetting of the shift rod / first pawl and automatic engagement of the first pawl with the first ratchet, thereby achieving the driving purpose of the first pawl. The shift rod has the advantages of simple structure, precise control and convenient assembly.

[0028] In any of the above technical solutions, the clutch also includes: a bottom shell, the first pawl, the second pawl, the first ratchet, the second ratchet and the second fork are all accommodated in the bottom shell, the second fork is arranged on the bottom shell, the first fork is located outside the bottom shell, and a part of the first fork extends into the bottom shell to drive the first pawl.

[0029] In the present solution, the first pawl, the second pawl, the first ratchet, the second ratchet and the second fork are all accommodated in the bottom shell of the clutch, which can improve the integration of the product, prevent the linkage process between the first fork (or the first pawl) and the second pawl from being obstructed or stuck, and is more conducive to the protection of the product. The first fork is arranged outside the bottom shell to facilitate the cooperation between the first fork and the external drive source, thereby facilitating the assembly of the product.

[0030] An embodiment of the second aspect of the present invention provides a clutch transmission system, comprising: a clutch sleeve; a clutch shaft; a wrap spring; the clutch described in any of the above technical solutions, wherein the wrap spring is connected to a first ratchet and a second ratchet of the clutch, wherein the first pawl of the clutch is engaged with the first ratchet and the second pawl is engaged with the second ratchet so that the wrap spring unlocks the clutch sleeve and the clutch shaft, and the first pawl is separated from the first ratchet and the second pawl is separated from the second ratchet so that the wrap spring locks the clutch sleeve and the clutch shaft.

DETAILED DESCRIPTION

[0045] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0046] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0047] Refer to the following Figures 1 to 7 The present invention describes a clutch, a clutch transmission system and a clothes treating device according to some embodiments of the present invention.

[0048] Embodiment 1:

[0049] like Figure 1 and Figure 2 As shown, the clutch provided in this embodiment includes: a first shift fork 110 , a first ratchet 130 , a second shift fork 210 and a second ratchet 230 .

[0050] Specifically, the first fork 110 is provided with a first pawl 120, and the first fork 110 is configured to drive the first pawl 120 so that the first pawl 120 engages or separates with the first ratchet 130; the second fork 210 is provided with a second pawl 220, and the second fork 210 is configured to drive the second pawl 220 so that the second pawl 220 engages or separates with the second ratchet 230.

[0051] The clutch provided by the above embodiment of the present invention is provided with a first fork 110 and a second fork 210 to respectively drive the first pawl 120 and the second pawl 220 accordingly, so as to form a double pawl structure using a split fork, so that the meshing and separation actions of the first pawl 120 and the first ratchet 130 and the meshing and separation actions of the second pawl 220 and the second ratchet 230 will not interfere with each other. In this way, the first fork 110 and the second fork 210 can realize the drive control of the first pawl 120 and the second pawl 220 with a smaller motion stroke. Compared with the integrated double pawl structure in which one fork is provided with two pawls, the motion stroke of the fork (the first fork 110 and the second fork 210) is greatly reduced, thereby correspondingly reducing the amount of space reserved for meeting the fork stroke requirements, which is more conducive to the compact design of the product and saves more product volume space. In addition, since the stroke of the fork (the first fork 110 and the second fork 210) is reduced, the risk of interference between the fork and surrounding components is reduced, which is more conducive to ensuring the operational reliability of the product.

[0052] Embodiment 2:

[0053] like Figure 2and Figure 6 As shown, in addition to the features of the above embodiment, this embodiment further defines: the second fork 210 includes a linkage mechanism (for details, see the attached Figure 6 The linkage mechanism transmits between the first fork 110 / the first pawl 120 and the second pawl 220, and when the first fork 110 drives the first pawl 120 to move to a position separated from the first ratchet 130, the first fork 110 / the first pawl 120 triggers the linkage mechanism to link with the second pawl 220, so that the second pawl 220 moves to a position separated from the second ratchet 230.

[0054] It is worth noting that linkage, as the name implies, can be understood as a number of related things. When one moves or changes, the others also move or change accordingly. This solution can be understood as using a linkage mechanism to associate the first fork 110 (or the first pawl 120) with the second pawl 220, so that when the first fork 110 / the first pawl 120 moves or changes, the second pawl 220 also moves or changes accordingly. The linkage specifically implemented by the linkage mechanism here at least includes: when the first fork 110 drives the first pawl 120 to move to a position separated from the first ratchet 130, the first fork 110 / the first pawl 120 triggers the linkage mechanism to link the second pawl 220, so that the second pawl 220 moves to a position separated from the second ratchet 230. That is, when the first pawl 120 moves to a position separated from the first ratchet 130, the second pawl 220 responds by moving to a position separated from the second ratchet 230.

[0055] In this way, in the double fork design of the present scheme, for the fork added compared to the related single fork technology, there is no need to separately add an external driving source to drive and control the added fork, which reduces the modification cost of the product and simplifies the structure of the product. It is also more conducive to ensuring the consistency of the separation of the first pawl 120 and the first ratchet 130 and the separation of the second pawl 220 and the second ratchet 230, thereby improving the accuracy of the clamping control of the clamping spring 430.

[0056] Furthermore, the linkage achieved by the linkage mechanism at least further includes: when the first fork 110 drives the first pawl 120 to move to a position meshed with the first ratchet 130, the first fork 110 / first pawl 120 triggers the linkage mechanism to link the second pawl 220, so that the second pawl 220 moves to a position meshed with the second ratchet 230. That is, when the first pawl 120 moves to a position meshed with the first ratchet 130, the second pawl 220 responds by moving to a position separated from the second ratchet 230.

[0057] In this way, in the double fork design of the present scheme, for the fork added compared to the related single fork technology, there is no need to separately add an external driving source to drive and control the added fork, which reduces the modification cost of the product and simplifies the structure of the product. It is also more conducive to ensuring the consistency of the engagement between the first pawl 120 and the first ratchet 130 and the engagement between the second pawl 220 and the second ratchet 230, thereby improving the accuracy of the release control of the wrap spring 430.

[0058] Embodiment 3:

[0059] like Figure 2 As shown, in addition to the features of the above-mentioned embodiment 2, this embodiment further defines that: the linkage mechanism includes a slider 211 and a movable member 212 .

[0060] Specifically, the slider 211 is provided with a first meshing portion 2111; the movable member 212 is provided with a second meshing portion 2121 and the second meshing portion 2121 meshes with the first meshing portion 2111 for transmission, the second pawl 220 is provided on the movable member 212, the first shift fork 110 / the first pawl 120 abuts against the slider 211 and drives the slider 211 to slide, so that the slider 211 drives the second pawl 220 to move toward the position meshed with the second ratchet 230 via the movable member 212. Among them, the meshing transmission has the advantages of good transmission stability and high transmission accuracy, which can help improve the movement accuracy of the second pawl 220 and the consistency of the movement with the first pawl 120, improve the accuracy of the release control of the wrap spring 430, and the meshing transmission has a good compact layout, which can further save product space.

[0061] like Figure 2 , Figure 6 and Figure 7 As shown, for example, the second meshing portion 2121 includes gear teeth, and the gear teeth are arranged along the outer periphery of the movable part 212, and the first meshing portion 2111 includes a rack, which is distributed on the peripheral side of the movable part 212 and is arc-shaped. In this way, by utilizing the arc-shaped rack to cooperate with the gear teeth, the movable part 212 can be driven to rotate when the slider 211 slides.

[0062] Of course, the present solution is not limited to this. In other embodiments, the second pawl 220 may not need to be rotated, but may be, for example, slidingly set. For example, when the first fork 110 drives the first pawl 120 to separate from the first ratchet 130, the second pawl 220 is driven radially away from the second ratchet 230 via the linkage mechanism to separate from the second ratchet 230, or the second pawl 220 is driven axially away from the second ratchet 230 via the linkage mechanism to separate from the second ratchet 230 by axial misalignment, etc.

[0063] Furthermore, the second pawl 220 protrudes from the movable member 212 to the side of the movable member 212, and the movable member 212 rotates to drive the second pawl 220 to rotate. The transmission chain has high transmission accuracy, compact structure, and small size. The second pawl 220 engages or separates with the second ratchet wheel 230 by swinging, and the required stroke is small, and the movement space required for the activity is small, which is more conducive to compact product layout, and can effectively avoid the problem of interference between the second pawl 220 and other components, thereby ensuring the reliability of the product.

[0064] More specifically, if Figure 7 As shown, the movable part 212 is a gear, and a part of the gear peripheral side wall is provided with gear teeth, and the gear teeth are multiple and distributed at intervals along the circumference of the gear. The other part of the gear peripheral side wall is not provided with gear teeth, but a second pawl 220 is provided on the surface of the other part of the gear peripheral side wall, and the second pawl 220 protrudes along the tangential direction of the gear peripheral side surface, and the rack is distributed on the side of the gear with the gear teeth, and the rack moves with the slider 211 to rotate the gear, and the rotation of the gear causes the second pawl 220 to swing to engage or separate with the ratchet teeth of the second ratchet wheel 230.

[0065] Of course, the present solution is not limited thereto. In other embodiments, according to needs, a transmission structure such as a crank rocker mechanism can also be used to transmit between the first fork 110 / the first pawl 120 and the second pawl 220 to realize the linkage engagement or opening of the second pawl 220. For example, the second pawl 220 is formed as a rocker of the crank rocker mechanism, and the crank rocker mechanism is driven by the movement of the first fork 110 or the first pawl 120, so that the swing is used as the output end of the transmission chain to swing and drive the second pawl 220 to swing.

[0066] Furthermore, if Figure 6 and Figure 7 As shown, the second shift fork 210 further includes a fixed block 213, and the movable member 212 and the slider 211 are arranged on the fixed block 213. In this way, the movable member 212 and the slider 211 are arranged on the same basis, and the transmission matching accuracy between the movable member 212 and the slider 211 can be higher, further improving the control accuracy of the first shift fork 110 (or the first pawl 120) on the second pawl 220.

[0067] In more detail, Figure 6 and Figure 7 As shown, a fixing column 2133 is provided on the fixing block 213, and the through hole of the movable member 212 is sleeved on the outer side of the fixing column 2133, so that the movable member 212 can rotate around the fixing column 2133, and the fixing column 2133 is used to make the movable member 212 accurately positioned on the fixing block 213 and not easily displaced. In this way, the meshing transmission cooperation between the movable member 212 and the slider 211 is more accurate and stable.

[0068] In addition, the fixed block 213 is slidably matched with the slider 211, and a guide structure 2131 is provided on the fixed block 213, and the guide structure 2131 cooperates with the slider 211 and guides the slider 211. The problem of the slider 211 moving out of position can be prevented, and the smoothness of the slider 211 sliding can be ensured, thereby further improving the control accuracy of the first fork 110 (or the first pawl 120) on the second pawl 220.

[0069] In detail, Figure 7 As shown, the guide structure 2131 includes a guide groove 21311 and a slide rail 21312 formed on the fixed block 213, the slider 211 is mounted on the slide rail 21312, and the slider 211 is provided with a convex edge 2112, which extends into the guide groove 21311 and slides along the guide groove 21311. The slider 211 is mounted on the slide rail 21312, and the slider 211 slides along the slide rail 21312, which can play a good guiding and limiting effect, making the slider 211 slide more accurately and smoothly, improving the transmission accuracy of the slider 211 between the first fork 110 (or the first pawl 120) and the second pawl 220, thereby further improving the control accuracy of the first fork 110 (or the first pawl 120) on the second pawl 220.

[0070] In more detail, Figure 7 As shown, the slider 211 is provided with an adapting slideway 2113, the shape of the slide rail 21312 is adapted and matched with the adapting slideway 2113, the adapting slideway 2113 and the slide rail 21312 are slidably matched so that the slider 211 and the fixed block 213 can slide with each other, and the fixed block 213 is provided with a guide groove 21311 at the side of the slide rail 21312, and the guide groove 21311 is defined by the undercut on the fixed block 213 which is roughly in an inverted L shape, and the undercut is buckled on the protruding side of the slider 211 On the convex edge 2112, in this way, on the one hand, the undercut can clamp the convex edge 2112 on the fixed block 213 to prevent the slider 211 from upwardly detaching from the surface of the fixed block 213, which can correspondingly limit the derailment between the adaptation slide 2113 and the slide rail 21312; on the other hand, the convex edge 2112 is embedded in the guide groove 21311 defined by the undercut and slides along the guide groove 21311, which can further guide the movement of the slider 211 and improve the assembly stability and sliding smoothness of the slider 211.

[0072] like Figure 6 and Figure 7As shown, in addition to the features of any of the above embodiments, this embodiment is further defined as follows: the linkage mechanism includes a first elastic member 214 connected to a second pawl 220, wherein the second pawl 220 compresses the first elastic member 214 at a position engaged with the second ratchet 230 so that the first elastic member 214 is compressed to store energy, and when the first fork 110 (or the first pawl 120) releases the second pawl 220, the first elastic member 214 elastically recovers to drive the second pawl 220 to separate from the second ratchet 230. The linkage action between the first fork 110 (or the first pawl 120) and the second pawl 220 is realized, and has the advantages of simple structure, precise control and easy assembly. It can be understood that for the transmission chain formed by the slider 211 and the movable member 212 included in the second fork 210, when the first elastic member 214 drives the second pawl 220 to automatically separate from the second ratchet 230, the elastic restoring force of the first elastic member 214 is transmitted along the transmission chain and can drive the sliding to automatically reset to a certain extent, thereby utilizing the reset of the slider 211 to further drive the first fork 110 (or the first pawl 120) abutting against it to reset, so as to facilitate the next drive of the slider 211 or the first pawl 120 to the slider 211.

[0073] For example, Figure 6 and Figure 7 As shown, the first elastic member 214 is a torsion spring having two pins, one of which abuts against the movable member 212, and the other abuts against the fixed block 213. Thus, when the movable member 212 rotates, the torsion spring provides the amount of rotation of the movable member 212 by deformation. When the external force is removed from the movable member 212, the torsion spring elastically returns to drive the movable member 212 to rotate and reset. The torsion spring has the advantages of simple structure, convenient assembly and low cost.

[0074] Of course, the present solution is not limited to the structural form in which the rebound force of the first elastic member 214 is used to drive the second pawl 220 to automatically reset so that the second pawl 220 and the second ratchet 230 are automatically separated. In other embodiments, a slider 211 may also be provided to be connected to the first fork 110 or the first pawl 120, so that when the first fork 110 or the first pawl 120 is reset, the slider 211 is pulled to reset, and the second pawl 220 is driven to reset through the transmission cooperation between the slider 211 and the movable member 212.

[0075] Embodiment 5:

[0076] like Figure 6As shown, in addition to the features of any of the above embodiments, this embodiment further defines that: the clutch further includes a stopper 2132, wherein when the second pawl 220 moves to a position separated from the second ratchet 230, the stopper 2132 stops and abuts against any one of the slider 211, the movable member 212 and the second pawl 220 to limit the second pawl 220 from continuing to move. On the one hand, while achieving the control requirements of the second pawl 220 engaging and separating with the second ratchet 230, the stroke of the second pawl 220 can be effectively limited, thereby increasing the control accuracy of the second pawl 220 and preventing the control requirement problem and interference risk problem caused by the excessive stroke of the second pawl 220. On the other hand, by using the first elastic member 214 to push the second pawl 220 against the stopper 2132, the second pawl 220 can be kept stable at the position separated from the second ratchet 230 to prevent the problem of looseness.

[0077] In a specific embodiment, Figure 7 As shown, the fixed block 213 is configured with a protrusion protruding from the surface of the fixed block 213, and the protrusion is formed as a stopper 2132. The protrusion is located on the side of the movable member 212 and is arranged adjacent to the movable member 212. When the second pawl 220 moves to a position separated from the second ratchet 230, the protrusion stops and abuts against the second pawl 220 to limit the second pawl 220 from continuing to move. It can be understood that, through the stopper 2132 and the second pawl 220, combined with the transmission chain (movable member 212, slider 211, etc.) between the second pawl 220 and the first fork 110 or the first pawl 120, the stopping effect can be transmitted to the first pawl 120 and the first fork 110, and the first pawl 120 and the first fork 110 are limited to continue to move.

[0078] Embodiment 6:

[0079] like Figure 1 and Figure 5 As shown, in addition to the features of any of the above embodiments, this embodiment further defines that: the first shift fork 110 includes: a shift rod 111 and a second elastic member 112 .

[0080] Specifically, the lever 111 is connected to the first pawl 120, and drives the first pawl 120 to make the first pawl 120 mesh with or separate from the first ratchet 130; the second elastic member 112 is connected to the lever 111 / first pawl 120, and the lever 111 / first pawl 120 compresses the second elastic member 112 when the first pawl 120 is separated from the first ratchet 130, and the second elastic member 112 elastically recovers to make the first pawl 120 mesh with the first ratchet 130. In this way, the lever 111 / first pawl 120 can be automatically reset, and the first pawl 120 can be automatically meshed with the first ratchet 130, so as to achieve the purpose of driving the first pawl 120, and the advantages of simple structure, precise control and convenient assembly are achieved.

[0081] For example, the lever 111 is used to cooperate with an external driving source (such as a motor, an electromagnet, a tractor, etc.), so that the external driving source drives the lever 111 to control the matching state of the first pawl 120 and the first ratchet 130 and the matching state of the second pawl 220 and the second ratchet 230. The second elastic member 112 can be specifically a torsion spring, one end of which is connected to the lever 111, and the other end is connected to the upper housing of the clutch or the bracket on the upper housing, so that the torsion spring is compressed or released during the movement of the lever 111.

[0082] Embodiment 7:

[0083] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in addition to the features of any of the above embodiments, this embodiment further defines: the clutch also includes a bottom shell 300, wherein, as shown in FIG. Figure 4 As shown, the first pawl 120, the second pawl 220, the first ratchet 130, the second ratchet 230 and the second fork 210 are all accommodated in the bottom shell 300, the second fork 210 is arranged on the bottom shell 300, the first fork 110 is located outside the bottom shell 300, and a part of the first fork 110 extends into the bottom shell 300 to drive the first pawl 120. This structure improves the integration of the product, and can prevent the linkage process between the first fork 110 (or the first pawl 120) and the second pawl 220 from being hindered or stuck, and is also more conducive to the protection of the product. The first fork 110 is arranged outside the bottom shell 300, which is convenient for the first fork 110 to cooperate with the external drive source, thereby facilitating the assembly of the product.

[0084] Furthermore, the second fork 210 (such as the slider 211, the movable part 212, etc.) is located on the inner side of the motor rotor. It can be understood that the present solution adopts a double fork structure design, which greatly reduces the activity space requirements of the first fork, the second fork, the first pawl, and the second pawl under the premise of meeting the driving requirements, and can achieve a more compact structure. In this way, for the double pawl solution, it is easier to realize the structural form in which the second fork 210, the first pawl, the second pawl, etc. are placed in the motor. Compared with the existing double pawl single fork structure, it avoids the problem that the fork is large in size and the activity space requirement is large, which leads to the problem that the fork movement effect is poor or difficult to install due to the motor hole volume. Specific embodiment:

[0086] like Figures 1 to 7 As shown, this specific embodiment provides a clutch, including: a first shift fork 110, a second shift fork 210, a first pawl 120, a first ratchet 130, a second pawl 220, a second ratchet 230 and a linkage mechanism.

[0087] The first pawl 120 is engaged or separated with the first ratchet 130, and the second pawl 220 is engaged or separated with the second ratchet 230, forming a double-pawl double-ratchet structure, wherein the first fork 110 and the second fork 210 are arranged to form a double-pawl fork split design structure, wherein the first fork 110 includes a shift rod 111 and a second elastic member 112, and its function is similar to the shift fork in the related single-pawl structure. The second shift fork 210 is fixed separately in the clutch bottom housing 300. More specifically, the second shift fork 210 is fixed separately in the clutch motor. The second shift fork 210 includes a movable member 212, a slider 211 and a first elastic member 214. The movable member 212 is a gear. The second pawl 220 is arranged on the gear. The slider 211 is provided with a rack. The rack meshes with the gear and rotates through the second pawl 220 through the gear transmission belt, so as to achieve the purpose of simultaneous separation between the first pawl 120 and the first ratchet 130 and between the second pawl 220 and the second ratchet 230.

[0088] like Figure 3 As shown, the clutch is arranged in the clutch drive system and forms a part of the clutch drive system. The clutch drive system is provided with a wrap spring 430, and the two ends of the wrap spring 430 are fixed to the first ratchet 130 and the second ratchet 230 respectively. The second fork 210 includes a fixed block 213, a slider 211 with a rack, a movable member 212 with a gear, a second pawl 220 arranged on the movable member 212, a first elastic member 214, etc. The second fork 210 is fixed to the clutch housing and is located on the inner side of the motor rotor. One end of the slider 211 is against the first fork 110, so that when the first fork 110 moves, the slider 211 is driven to move.

[0089] In the dehydration condition, the lever 111 is opened, and the lever 111 drives the first pawl 120 to move away from the first ratchet 130, so that the first pawl 120 is separated from the first ratchet 130. At the same time, the lever 111 releases the slider 211. At this time, the elastic restoring force of the first elastic member 214 drives the second pawl 220 to rotate, so that the second pawl 220 is separated from the second ratchet 230. When the second pawl 220 rotates, the second pawl 220 further drives the slider 211 to slide and reset through the gear rack transmission. The second pawl 220 stops rotating when it rotates to the stopper 2132 of the fixed block 213. At this time, the second pawl 220 and the second ratchet 230 are completely separated. In this way, under the dehydration condition, the ratchets at both ends of the spring 430 are separated from the fork pawls (the first pawl 120 is separated from the first ratchet 130, and the second pawl 220 is separated from the second ratchet 230), and the restoring force of the spring 430 itself holds the clutch sleeve 410 and the clutch shaft 420, so that the dehydration shaft 510 can rotate simultaneously under the drive of the driving device.

[0090] Under the washing condition, the lever 111 of the first shift fork 110 returns to its original position under the elastic restoring force of the second elastic member 112. When the lever 111 returns to its original position, the first pawl 120 is driven to move so that the first pawl 120 is meshed with the first ratchet 130, so that the first pawl 120 opens the first ratchet 130 by a certain angle and then opens the wrap spring 430. At the same time, the first shift fork 110 pushes the slider 211 in the second shift fork 210 to slide, and the slider 211 drives the second pawl 220 to rotate through the gear transmission while sliding. During the rotation process, the second pawl 220 meshes with the second ratchet 230, so that the second pawl 220 pushes the second ratchet 230 to rotate by a certain angle to open the wrap spring 430. At this time, both the first ratchet 130 and the second ratchet 230 push the wrap spring 430 to open, so that the clutch sleeve 410 is separated from the wrap spring 430. At this time, the brake disc is in a free state and can rotate at will. The dehydration shaft 510 does not rotate with the washing shaft 520. In the inner barrel, under the state of water inertia, the rotation directions of the inner barrel and the impeller can be opposite, forming a water flow effect similar to dual power, producing a hand-rubbing washing effect.

[0091] Embodiment 8:

[0092] like Figure 2 As shown, this embodiment provides a clutch transmission system, including: a clutch sleeve 410, a clutch shaft 420, a wrap spring 430 and the clutch described in any of the above embodiments.

[0093] The wrap spring 430 is connected to the first ratchet 130 and the second ratchet 230 of the clutch, wherein the first pawl 120 of the clutch is engaged with the first ratchet 130 and the second pawl 220 is engaged with the second ratchet 230 so that the wrap spring 430 unlocks the clutch sleeve 410 and the clutch shaft 420, and the first pawl 120 is separated from the first ratchet 130 and the second pawl 220 is separated from the second ratchet 230 so that the wrap spring 430 locks the clutch sleeve 410 and the clutch shaft 420.

[0094] The clutch transmission system provided in the above embodiment of the present invention has all the above beneficial effects by being provided with the clutch described in any of the above technical solutions, which will not be described in detail here.

[0095] Embodiment 9:

[0096] This embodiment provides a clothes processing device, including: a washing execution component, a dehydration execution component, a driving device and the clutch transmission system described in any of the above embodiments, and the clutch transmission system is connected to the washing execution component, the dehydration execution component and the driving device.

[0097] The clothes processing device provided by the above embodiments of the present invention has all the above beneficial effects by being provided with the clutch transmission system described in any of the above technical solutions, which will not be described in detail here.

[0098] For example, the clothing processing device may be a washing machine, or a washing-drying machine, etc. The washing execution component may be specifically a pulsator, and the dehydration execution component may be specifically an inner barrel, wherein the clutch transmission system further comprises a washing shaft 520 and a dehydration shaft 510, wherein the dehydration shaft 510 is connected to the inner barrel, and the washing shaft 520 is connected to the pulsator. In the dehydration condition, the wrap spring 430 locks the clutch sleeve 410 and the clutch shaft 420 and locks the washing shaft 520 and the dehydration shaft 510, and the dehydration shaft 510 rotates with the washing shaft 520, so that the inner barrel performs a dehydration action. In the washing condition, the wrap spring 430 unlocks the clutch sleeve 410 and the clutch shaft 420 and allows the washing shaft 520 and the dehydration shaft 510 to rotate relative to each other, and the washing shaft 520 rotates to drive the pulsator to rotate to perform the washing action, and the dehydration shaft 510 and the washing shaft 520 can rotate relative to each other.

[0099] To sum up, the clutch, clutch drive system and clothing processing equipment provided by the present invention form a double pawl structure using a split fork. In this way, the first fork and the second fork can realize drive control of the first pawl and the second pawl with a smaller motion stroke. Compared with the integrated double pawl structure in which one fork is provided with two pawls, the motion stroke of the fork (the first fork and the second fork) is greatly reduced, thereby correspondingly reducing the amount of space reserved for meeting the fork stroke requirements, which is more conducive to the compact design of the product, saves more product volume space, reduces the risk of interference between the fork and surrounding components, and is more conducive to ensuring the operational reliability of the product.
