In detail, the clutch device 100 further includes a transmission shaft assembly 110, a clutch member 140, a first driving mechanism 150 and a second driving mechanism 250, wherein the clutch member 140 is movably connected to at least one transmission shaft in the transmission shaft assembly 110, at least a portion of the guide member 130 abuts against at least a portion of the clutch member 140 to stop the clutch member 140, when the second transmission member 163 moves to cancel the abutment with the guide member 130, the guide member 130 can cancel the stop of the clutch member 140, the first driving mechanism 150 includes a first elastic member 151, at least a portion of the first elastic member 151 abuts against at least a portion of the clutch member 140, when the guide member 130 cancels the stop of the clutch member 140, the first elastic member 151 can drive the clutch member 140 to move along the axial direction of the transmission shaft assembly 110 to change the connection position of the clutch member 140 with the at least one transmission shaft, the second driving mechanism 250 can drive the clutch member 140 to rotate, such that clutch 140 can rotate at least one of the drive shafts of drive shaft assembly 110.

In some embodiments, under the driving of the driving member 161, the first transmission member 162 can drive one end of the second transmission member 163 to move once, so that the other end of the second transmission member 163 can cancel the abutment on the guide member 130 once, when the second transmission member 163 cancels the abutment on the guide member 130, the stop of the guide member 130 on the clutch member 140 is cancelled indirectly, so that the first elastic member 151 can drive the clutch member 140 to move axially along the transmission shaft assembly 110, it can be understood that at least one part of the clutch member 140 abuts on at least one part of the guide member 130, that is, the clutch member 140 can push the guide member 130 to move axially during the axial movement, when the first elastic member 151 drives the clutch member 140 to move axially along the transmission shaft assembly 110 for a certain stroke, the relative connection position between the clutch member 140 and at least one transmission shaft in the transmission shaft assembly 110 can be changed, this provides a first stroke of axial movement of the guide 130 and the clutch 140 for the drive means 160. In some embodiments, the clutch 140 can rotate at least one transmission shaft engaged with the clutch 140 in the transmission shaft assembly 110 under the driving of the second driving mechanism 250. In some embodiments, when the second transmission member 163 repels the contact with the guide member 130 for multiple times, the first elastic member 151 can drive the clutch member 140 to move along the axial direction of the transmission shaft assembly 110 for multiple times to perform multiple strokes, so as to repeatedly change the connection position between the clutch member 140 and at least one transmission shaft in the transmission shaft assembly 110, thereby realizing different power transmission between the clutch member 140 and the at least one transmission shaft, further realizing multiple rotation forms of each transmission shaft in the transmission shaft assembly 110, and satisfying multiple washing forms of the laundry treatment apparatus, so that the movement forms of the water flow are more diverse, the use function can be adjusted according to the customer demands, the laundry treatment apparatus is closer to the user demands, and the cleanliness is also improved.

In some embodiments, when the clutch 140 is in the initial state, the clutch 140 and the at least one transmission shaft are engaged in a first manner, when the first elastic member 151 drives the clutch 140 to move for a first stroke, the clutch 140 and the at least one transmission shaft are engaged in a second manner due to the change of the relative connection position between the clutch 140 and the at least one transmission shaft, and when the first elastic member 151 drives the clutch 140 to move for a second stroke, the clutch 140 and the at least one transmission shaft are engaged in a third manner due to the change of the relative connection position between the clutch 140 and the at least one transmission shaft, it can be understood that when the second transmission member 163 is disengaged from the guide 130 for a plurality of times under the driving of the driving member 161, the first elastic member 151 can drive the clutch 140, the structure of the clutch member 140 may be specifically configured to satisfy various engagement manners between the clutch member 140 and at least one driving shaft by the multi-stroke movement of the guide member 130 driven by the clutch member 140.

In some embodiments, the second driving mechanism 250 can drive the clutch 140 to rotate, so that the rotation of the clutch 140 can drive at least one transmission shaft in the transmission shaft assembly 110 to rotate, it can be understood that when the first elastic member 151 drives the clutch 140 so that the clutch 140 and the at least one transmission shaft are in different relative connection positions, and the second driving mechanism 250 drives the clutch 140 to rotate, the clutch 140 can drive the at least one transmission shaft in matching connection therewith to rotate, so that when the first elastic member 151 drives the clutch 140 to axially move so that the clutch 140 and the at least one transmission shaft are in different matching modes, the rotation of the at least one transmission shaft in the transmission shaft assembly 110 can be realized under the driving of the second driving mechanism 250.

For example, the transmission shaft assembly 110 includes a first transmission shaft 111, a second transmission shaft 112 and a third transmission shaft 113, when the clutch 140 is at the initial position, the clutch 140 is engaged with the first transmission shaft 111, and when the second driving mechanism 250 drives the clutch 140 to rotate, the clutch 140 can drive the first transmission shaft 111 to rotate independently. When the first elastic member 151 drives the clutch member 140 to move along the axial direction of the transmission shaft assembly 110 by a first stroke, the clutch member 140 is simultaneously engaged with the first transmission shaft 111 and the second transmission shaft 112, so that the clutch member 140 can drive the first transmission shaft 111 and the second transmission shaft 112 to simultaneously rotate under the driving of the second driving mechanism 250. When the first elastic member 151 drives the clutch member 140 to move again along the axial direction of the transmission shaft assembly 110 for a second stroke, the clutch member 140 can be simultaneously coupled to the first transmission shaft 111, the second transmission shaft 112 and the third transmission shaft 113, and further, under the driving of the second driving mechanism 250, the clutch member 140 can drive the first transmission shaft 111, the second transmission shaft 112 and the third transmission shaft 113 to simultaneously rotate, that is, the clutch member 140 is driven by the first elastic member 151 to perform axial displacement, so that the clutch member 140 and at least one transmission shaft are in multiple different coupling manners, thereby realizing multiple rotation manners of rotation of at least one transmission shaft in the transmission shaft assembly 110, when the clutch device 100 is applied to a laundry treatment device, the laundry treatment device is provided with a first pulsator, a second pulsator and a tub, specifically, the first transmission shaft 111 is connected to the first pulsator, the second transmission shaft 112 is connected to the second pulsator, the third transmission shaft 113 is connected with the barrel body, so that various washing forms of the clothes treatment device can be realized, the movement forms of water flow are more various, the use function can be adjusted according to the requirements of customers, the use function is closer to the requirements of users, and the cleanliness is improved.

In addition, the second driving mechanism 250 can directly drive one of the transmission shafts in the transmission shaft assembly 110, for example, the second driving mechanism 250 directly drives the first transmission shaft 111, so that the first transmission shaft 111 drives the clutch member 140 to rotate, and further, when the clutch member 140 is cooperatively connected with the second transmission shaft 112 or the clutch member 140 is cooperatively connected with the second transmission shaft 112 and the third transmission shaft 113, the clutch member 140 can drive the second transmission shaft 112 or the second transmission shaft 112 and the third transmission shaft 113 to rotate. The first transmission shaft 111 is directly driven by the second driving mechanism 250, so that the input and the output of power can be realized as one shaft, the matching precision between the second driving mechanism 250 and the first transmission shaft 111 is improved, and the vibration and the noise caused by poor coaxiality between at least one transmission shaft are effectively reduced. In addition, the second driving mechanism 250 is directly connected to the first transmission shaft 111, so that the problems of high cost of the clutch device 100 and high noise and vibration generated in the operation process of the clutch device 100 due to the fact that the transmission of power is realized through a planetary gear speed reducing mechanism in the related art can be solved.

The output rotating speed of the second driving mechanism 250 can be adjusted, that is, the second driving mechanism 250 comprises a DD motor, the DD motor can directly realize speed reduction and reversing, the rotating torque is large, and accurate control of the rotating process of the clutch assembly can be realized. The DD motor can realize the adjustment of the rotating speed of the first transmission shaft 111, so that the washing forms of the clothes treatment device with the clutch device 100 are enriched, when the impeller is connected with the first transmission shaft 111, the rotating speed of the impeller can be adjusted according to the actual needs of a user, and the use experience of the user is further improved.

It should be noted that the clutch member 140 can be made of plastic, which can further reduce the cost of the whole clutch device 100.

In some embodiments, the first transmission member 162 may move to drive one end of the second transmission member 163 to move upwards for a certain distance, and the other end of the second transmission member 163 may move downwards for a certain distance, that is, the second transmission member 163 may be set to be a lever structure, a rotating shaft may be disposed in the middle of the second transmission member 163, and the rotating shaft serves as a fulcrum, so that when one end of the second transmission member 163 moves upwards, the other end of the second transmission member 163 moves downwards, so that when the other end of the second transmission member 163 moves downwards, the abutting state with the guide member 130 can be cancelled, that is, the stopping of the second transmission member 163 on the clutch member 140 is indirectly cancelled, which further simplifies the structure of the driving device 160, and when the second transmission member 163 abuts against the guide member 130, the first elastic member 151 can drive the clutch member 140 to move axially along the transmission shaft assembly 110 and push the guide member 130 to move axially, the axial movement of the clutch member 140 can change the connection state between the clutch member 140 and at least one transmission shaft in the transmission shaft assembly 110, and then the clutch member 140 can drive at least one transmission shaft in the transmission shaft assembly 110 to rotate under the driving of the second driving mechanism 250, so as to realize the multi-stage power transmission of the clutch device 100.

The driving member 161 includes a retractor, the second transmission member 163 includes a shaft hole 1633 in the middle, and a shift lever having a rotating shaft is disposed in the shaft hole 1633, one end of the shift lever is connected to the first transmission member 162, the other end of the shift lever abuts against at least a portion of the guide member 130, and two ends of the shift lever can use the rotating shaft as a fulcrum to implement lever motion. Specifically, the retractor contracts a first stroke, the first transmission member 162 moves a certain distance, and meanwhile, one end of the driving lever is driven to move upwards for a certain distance, and the other end of the driving lever moves downwards for a certain distance, so that the other end of the driving lever is not abutted to the guide member 130 any more, which is the first stroke of the driving device 160, and the guide member 130 cancels a stop of the clutch member 140, so that the first elastic member 151 can drive the clutch member 140 to move axially for a first stroke, and a second matching mode of the clutch member 140 and the transmission shaft assembly 110 is realized.

The retractor contracts a second stroke, the first transmission member 162 moves a certain distance again, and simultaneously drives one end of the driving lever to move a certain distance upwards again, and the other end of the driving lever moves a certain distance downwards again, so that the other end of the driving lever and the guide member 130 cancel the abutting connection again, which is the second stroke of the driving device 160 and also the stopping connection of the guide member 130 to the clutch member 140 is canceled for the second time, and thus the first elastic member 151 can drive the clutch member 140 to axially move a second stroke again, and a third matching mode of the clutch member 140 and the transmission shaft assembly 110 is realized. The retraction stroke of the specific retractor can be set according to actual needs to control the times of the second transmission member 163 and the guide member 130 withdrawing the abutment, and further indirectly control the times of the guide member 130 withdrawing the stop from the clutch member 140, so as to control the matching manner of the clutch member 140 and the transmission shaft assembly 110, and realize the multi-stage power transmission of the clutch device 100.

It can be understood that the driving stroke of the driving element 161 is positively correlated to the displacement of the first transmission element 162 and the second transmission element 163, that is, the larger the retraction stroke of the tractor is, the larger the displacement of the first transmission element 162 and the second transmission element 163 is, and the larger the axial displacement of the guide element 130 is. It can be appreciated that the travel of the retractor is not likely to be too great, and if the travel of the retractor is too great, the axial displacement of the corresponding guide 130 is greater, which in turn makes the clutch device 100 more bulky, increasing the production cost of the clutch device 100. Accordingly, the travel of the retractor is also not likely to be too small, and if the travel of the retractor is too small, the axial displacement of the guide 130 is smaller, thereby increasing the difficulty of the engagement between the guide 130 and other structures of the clutch device 100, or other structures of the clutch device 100. Therefore, it is necessary to properly design the stroke of the retractor so as to ensure stable operation of the clutch device 100 while simplifying the structure of the clutch device 100.

In addition, the first transmission member 162 may be provided with a groove engaged with the second transmission member 163, or may be provided with a cam or a spiral structure to realize the up-and-down movement of the second transmission member 163, so that the first transmission member 162 can move to drive the second transmission member 163 to move, and the second transmission member 163 can move to cancel the abutting state with the guide member 130. The method is specifically set according to actual needs.

In some embodiments, first drive mechanism 150 further includes a second resilient member 152, at least a portion of first resilient member 151 abutting at least a portion of clutch member 140, second resilient member 152 being disposed outboard of guide member 130. Since at least a portion of the guiding element 130 abuts against at least a portion of the clutch element 140, when the other end of the second transmission element 163 is released from abutting against the guiding element 130 for the first time, the first elastic element 151 can drive the clutch element 140 to move axially and push the guiding element 130 to move during the movement of the clutch element 140 until the guiding element 130 abuts against the other end of the second transmission element 163 again, at which time the second elastic element 152 is compressed, which is the first stroke of the clutch element 140.

When the other end of the second transmission member 163 cancels the abutment on the guide member 130 for the second time, the first elastic member 151 can drive the clutch member 140 to axially move again, and push the guide member 130 to move again in the moving process until the guide member 130 abuts on the other end of the second transmission member 163, and the second elastic member 152 is compressed again, which is the second stroke of the clutch member 140.
