However, it will be appreciated that the present application can be practiced in a variety of ways beyond the specific details set forth herein, assuming that the fundamental underlying principles are maintained. It should also be appreciated that the present application can be practiced by employing only some of the described implementations. Accordingly, the present application is not to be limited in scope by the specific implementations disclosed in the following description, which are intended as illustrations of one or more aspects of the present application.

[0031] Second, the "one embodiment" or "an embodiment" appearing in the specification herein indicates that a specific feature, structure, or characteristic can be included in at least one implementation of the present application. The "in one embodiment" appearing in different places in the specification herein does not all refer to the same embodiment, nor is it an embodiment that is mutually exclusive with other embodiments.

[0032] Embodiment 1

[0033] Reference Figures 1-10 For the first embodiment of the present application, the embodiment provides a washing machine clutch main shaft, the washing machine clutch main shaft comprising a main body assembly 100 and an auxiliary assembly 200, and the auxiliary assembly 200 can timely stop the rotation of the dewatering shaft 105.

[0034] The main body assembly 100 comprises a shell 101, an upper cover 102, a washing shaft 103, a brake disc 104, a dewatering shaft 105, an impeller shaft 106, and a fork 107. The upper cover 102 is arranged on one side of the shell 101, the washing shaft 103 is arranged on one side of the shell 101, the brake disc 104 is arranged in the shell 101, the dewatering shaft 105 is inserted into the brake disc 104, the impeller shaft 106 is arranged in the dewatering shaft 105, and the fork 107 is arranged on one side of the shell 101.

[0035] The upper cover 102 is fixed to the shell 101 by screws, the washing shaft 103 is connected with a belt pulley, for driving the dewatering shaft 105 and the impeller shaft 106 to rotate respectively, the impeller shaft 106 is connected with an impeller, for driving the impeller to rotate, the dewatering shaft 105 is connected with a drum, for driving the drum to rotate, the brake disc 104 is provided with a brake belt on the outside, the fork 107 is rotatably connected to one side of the shell 101 through a rotating shaft, the brake belt is connected with the fork 107, and the fork 107 is used to drive the brake belt to move, so that the brake belt can contact the brake disc 104 and brake the brake disc 104. This is the prior art, and the present scheme will not be described in detail, and those skilled in the art can clearly understand the working principle.

[0036] The auxiliary assembly 200 arranged in the shell 101 comprises a locking piece 201, a rotating piece 202, a limiting piece 203, a pushing piece 204 and a separating piece 205. The locking piece 201 is arranged outside the dehydration shaft 105. The rotating piece 202 is arranged on the locking piece 201. The limiting piece 203 is arranged in the locking piece 201. The pushing piece 204 is arranged on one side of the limiting piece 203. The separating piece 205 is arranged on one side of the pushing piece 204.

[0037] When the drum finishes the dehydration of the clothes, the dehydration shaft 105 and the drum need to be braked. During the braking process, when the dehydration shaft 105 rotates for a small number of turns, the locking piece 201 can completely lock the dehydration shaft 105, so that the drum can stop rotating in time, thereby avoiding the situation that the user accidentally clamps the hand when taking the clothes. The rotating piece 202 is arranged to drive the locking piece 201 to move, so that the locking piece 201 can lock or separate from the dehydration shaft 105.

[0038] The limiting piece 203 is arranged to limit the locking piece 201. When the locking piece 201 locks the dehydration shaft 105, the limiting piece 203 can prolong the locking time of the dehydration shaft 105, so that the dehydration shaft 105 can stop rotating after rotating for a small number of turns, thereby avoiding the situation that when the dehydration shaft 105 rotates at a high speed, the locking piece 201 locks the dehydration shaft 105, which increases the friction of the locking piece 201 and shortens the service life of the locking piece 201.

[0039] The pushing piece 204 is arranged. When the brake band brakes the brake disc 104, the brake disc 104 rotates intermittently to push the limiting piece 203 to move, so that the limiting piece 203 can intermittently release the limitation of the locking piece 201, thereby delaying the locking of the locking piece 201 to the dehydration shaft 105. The separating piece 205 is arranged. When the dehydration shaft 105 drives the drum to rotate and dehydrates the clothes, the brake disc 104 can be separated from the pushing piece 204, so that the brake disc 104 does not drive the pushing piece 204 to move, thereby avoiding the situation that the locking piece 201 locks the dehydration shaft 105 during the dehydration process.

[0040] Embodiment 2

[0041] Reference Figures 1-10 This is the second embodiment of the application, which is based on the previous embodiment.

[0042] Specifically, the locking piece 201 comprises a limiting gear 201a, a tooth block 201b, a tooth plate 201c, a limiting rod 201d and a first spring 201e. The limiting gear 201a is located outside the dehydration shaft 105. The tooth block 201b is fixed outside the dehydration shaft 105. A tooth groove 201a-1 is formed in the inner side of the limiting gear 201a. The tooth block 201b is clamped with the tooth groove 201a-1. The tooth plate 201c is located outside the limiting gear 201a. A groove 105a is formed in the dehydration shaft 105. The limiting rod 201d is located in the groove 105a. The two ends of the first spring 201e are fixed with the limiting rod 201d and the inner wall of the groove 105a respectively. A limiting hole 201a-2 is formed in the limiting gear 201a. The limiting rod 201d is clamped with the limiting hole 201a-2.

[0043] The limiting gear 201a is connected with the dehydration shaft 105 through the cooperation of the tooth block 201b and the tooth groove 201a-1, so that the limiting gear 201a can rotate synchronously with the dehydration shaft 105. The tooth plate 201c is arc-shaped and has four numbers, which are evenly distributed outside the limiting gear 201a in a ring shape.

[0044] When the tooth plate 201c is engaged with the limiting gear 201a, the limiting gear 201a can be locked, so that the limiting gear 201a cannot rotate, thereby the dehydration shaft 105 and the roller can be locked, so that the roller can stop rotating in time, avoiding the case that the user accidentally clamps the hand when taking clothes. When the tooth plate 201c is separated from the limiting gear 201a, the dehydration shaft 105 and the roller can be released, so that they can rotate.

[0045] The end of the limiting rod 201d is arc-shaped, which is used for locking the limiting gear 201a through the cooperation of the limiting hole 201a-2, avoiding the case that the limiting gear 201a moves linearly outside the dehydration shaft 105 and is separated from the dehydration shaft 105, and facilitating the replacement of the limiting gear 201a. The first spring 201e applies a pushing force to the limiting rod 201d, so that the limiting rod 201d is more tightly clamped with the limiting hole 201a-2, avoiding the separation of the two.

[0046] Specifically, the locking piece 201 further comprises a positioning sleeve 201f, a positioning rod 201g and a second spring 201h. The positioning sleeve 201f is fixed to one side of the tooth plate 201c. One end of the positioning rod 201g is fixed with the inner wall of the shell 101, and the other end is inserted into the positioning sleeve 201f. The two ends of the second spring 201h are fixed with the positioning rod 201g and the inner wall of the positioning sleeve 201f respectively.

[0047] The number of positioning sleeves 201f corresponds to the tooth plate 201c, the positioning sleeve 201f is movably connected in the positioning rod 201g, and the two are used for positioning the tooth plate 201c to avoid the tooth plate 201c from deviating when moving. When the positioning sleeve 201f drives the tooth plate 201c to separate from the limiting gear 201a, the positioning sleeve 201f will extrude the second spring 201h, and when the positioning sleeve 201f is released, the second spring 201h can exert a pushing force on the positioning sleeve 201f, and the tooth plate 201c is driven by the positioning sleeve 201f to engage with the limiting gear 201a.

[0048] Specifically, the rotating member 202 includes a rotating disc 202a, a guide shaft 202b, a connecting ring 202c, a supporting ring 202d, and a supporting column 202e. The rotating disc 202a is located at the bottom of the positioning sleeve 201f, and the guide shaft 202b is fixed to the bottom of the positioning sleeve 201f. The rotating disc 202a is provided with a guide groove 202a-1, and the guide shaft 202b slides in the guide groove 202a-1. The connecting ring 202c is fixed to the bottom of the rotating disc 202a, the supporting ring 202d is rotatably connected in the connecting ring 202c, and the supporting column 202e is fixed to the inner wall of the shell 101 at both ends.

[0049] The number of guide shafts 202b corresponds to the number of positioning sleeves 201f, and the guide groove 202a-1 is arc-shaped, with both ends located on the inner side and the outer side of the rotating disc 202a. When the rotating disc 202a rotates, the guide shaft 202b can slide along the inner wall of the guide groove 202a-1, and the two can drive the positioning sleeve 201f to move.

[0050] The supporting ring 202d is rotatably connected in the connecting ring 202c through a bearing, and the two are used for supporting and positioning the rotating disc 202a to avoid deviation of the rotating disc 202a. The number of supporting columns 202e is two, which are respectively located at both ends of the supporting ring 202d, and are used for supporting and fixing the supporting ring 202d.

[0051] Specifically, the rotating member 202 further includes a connecting rod 202f, a rotating rod 202g, a stabilizing shaft 202h, and a torsional spring 202i. The connecting rod 202f is fixed to one side of the rotating disc 202a, the rotating rod 202g is located on one side of the connecting rod 202f, one end of the stabilizing shaft 202h is fixed to the inner wall of the shell 101, and the torsional spring 202i is fixed to the rotating rod 202g and the stabilizing shaft 202h at both ends.

[0052] The end of the shift fork 107 is fixed with an extension rod, the stabilizing shaft 202h is rotatably connected with the center of the rotating rod 202g, one side of the top end of the rotating rod 202g is in contact with the connecting rod 202f, and the other side of the bottom end is in contact with the extension rod.

[0053] When the fork 107 drives the brake belt to separate from the brake disc 104, the fork 107 will simultaneously drive the extension rod to move, and the extension rod pushes the bottom end of the rotating rod 202g to move, so that the top end of the rotating rod 202g pushes the connecting rod 202f to move, and then the connecting rod 202f drives the rotating disc 202a to rotate. When the fork 107 resets, the extension rod is separated from the rotating rod 202g. At this time, the rotating rod 202g is reset by the return force of the torsional spring 202i, and is separated from the connecting rod 202f.

[0054] Specifically, the limiting piece 203 includes a limiting block 203a and a third spring 203b. The positioning rod 201g is provided with a movable slot 201g-1. The limiting block 203a is located in the movable slot 201g-1. The third spring 203b has two ends respectively fixed with the limiting block 203a and the inner wall of the movable slot 201g-1. The positioning sleeve 201f is provided with a limiting slot 201f-1. The limiting block 203a is clamped with the limiting slot 201f-1. The number of the limiting slots 201f-1 is multiple, and they are linearly distributed on the positioning sleeve 201f.

[0055] The side of the limiting block 203a is inclined. Through the cooperation of the limiting block 203a and the limiting slot 201f-1, the positioning sleeve 201f is limited, so that the positioning sleeve 201f can move away from the limiting gear 201a, and cannot move close to the limiting gear 201a. The third spring 203b applies a pushing force to the limiting block 203a, so that the limiting block 203a is clamped with the limiting slot 201f-1 more tightly, and separation of the two is avoided.

[0056] When the positioning sleeve 201f drives the tooth plate 201c to separate from the limiting gear 201a, and the positioning sleeve 201f moves to a specified position, the limiting block 203a is clamped with the limiting slot 201f-1 at the end at this time. When the brake belt contacts the brake disc 104, the limiting block 203a is separated from the limiting slot 201f-1 with the rotation of the brake disc 104. In this way, the limitation on the positioning sleeve 201f is removed, so that the positioning sleeve 201f can drive the tooth plate 201c to move close to the limiting gear 201a. Under the condition that the brake disc 104 rotates one circle, the positioning sleeve 201f moves a distance of one limiting slot 201f-1. With the rotation of the brake disc 104, after the brake disc 104 rotates a small number of circles, the limiting block 203a is clamped with the limiting slot 201f-1 at the other end. At this time, the tooth plate 201c is engaged with the limiting gear 201a, so that the dehydration shaft 105 is locked, and the roller stops rotating in time.

[0060] The inner wall of the stress slot 203a-1 is inclined, the end of the extruding rod 204b is inclined, and the inclined surface thereof is in contact with the pushing rod 204a, when the end of the extruding rod 204b is extruded against the pushing rod 204a, the pushing rod 204a is pushed to move, and the pushing rod 204a is extruded against the inner wall of the stress slot 203a-1, so that the limiting block 203a is separated from the limiting slot 201f-1, and the limiting to the positioning sleeve 201f is released.

[0064] When the brake disc 104 rotates, the extruding block 204g is driven to rotate, and the extruding block 204g extrudes the connecting sleeve 204e, so that the connecting sleeve 204e drives the extruding rod 204b to move upward, and with the rotation of the brake disc 104, the extruding block 204g intermittently drives the connecting sleeve 204e to move upward.

[0065] Specifically, the separating piece 205 comprises a movable strip 205a, a fixed rod 205b, a limiting strip 205c, a pressing strip 205d and a stress block 205e. The movable strip 205a is located at one side of the supporting ring 202d, the fixed rod 205b is fixed to the end of the movable strip 205a, the limiting strip 205c is fixed to one side of the movable strip 205a, the pressing strip 205d is fixed to the bottom of the movable strip 205a, and the stress block 205e is fixed to one side of the connecting sleeve 204e. The pressing rod 204b is provided with a positioning groove 204b-1 corresponding to the limiting strip 205c.

[0066] The movable strip 205a is in an arc shape, the end of the fixed rod 205b is in contact with the rotating rod 202g, and one side of the stress block 205e is in an inclined shape.

[0067] When the rotating rod 202g rotates, the fixed rod 205b is simultaneously pushed to move, and the movable strip 205a is driven to move through the fixed rod 205b, so that the movable strip 205a drives the limiting strip 205c to be clamped with the positioning groove 204b-1, and the extrusion rod 204b is locked through cooperation of the two, so that it cannot move upward, thereby avoiding the situation that the extrusion rod 204b moves upward in the dehydration process, which causes the positioning sleeve 201f to drive the tooth plate 201c to engage with the limiting gear 201a.

[0068] At the same time, the pressing strip 205d extrudes the inclined surface of the stress block 205e, and the connecting sleeve 204e is driven to move upward through cooperation of the two, so that the bottom end of the connecting sleeve 204e is higher than the extrusion block 204g, thereby avoiding the situation that the extrusion block 204g contacts with the connecting sleeve 204e when moving.

[0069] Specifically, the separating piece 205 further comprises a stabilizing frame 205f, a supporting block 205g and a sixth spring 205h. The stabilizing frame 205f is fixed to one side of the supporting ring 202d, one side of the supporting block 205g is fixed with the movable strip 205a, and the sixth spring 205h is fixed at both ends with the supporting block 205g and the stabilizing frame 205f.

[0070] The number of the stabilizing frame 205f is two, which are respectively located at both ends of the outside of the movable strip 205a. The movable strip 205a is movably connected with the stabilizing frame 205f, and is positioned by the stabilizing frame 205f, so as to avoid the situation that the movable strip 205a deviates when moving

[0071] When the movable strip 205a moves, the supporting block 205g will press the sixth spring 205h, and when the rotating rod 202g resets and is separated from the fixed rod 205b, the sixth spring 205h will exert a pushing force on the supporting block 205g, and the movable strip 205a will reset through the supporting block 205g. In this way, the limiting strip 205c can be separated from the positioning groove 204b-1, thereby releasing the restriction on the pressing rod 204b. At the same time, the pressing strip 205d will be separated from the stressed block 205e, and the connecting sleeve 204e will descend to the initial position. At this time, the pressing block 204g can press the connecting sleeve 204e when it moves.

[0072] In use, when the clothes are dehydrated, the fork 107 will separate the brake band from the brake disc 104, and at the same time, the fork 107 will move the extension rod, and the extension rod will push the bottom end of the rotating rod 202g to move, so that the top end of the rotating rod 202g pushes the connecting rod 202f to move, thereby making the connecting rod 202f drive the rotating disc 202a to rotate. When the rotating disc 202a rotates, the guide shaft 202b can slide along the inner wall of the guide groove 202a-1, and the positioning sleeve 201f can be driven to move by cooperation between the two, so that the positioning sleeve 201f drives the tooth plate 201c to separate from the limiting gear 201a. In this way, the restriction on the dehydration shaft 105 can be released, so that the dehydration shaft 105 can drive the drum to rotate and dehydrate the clothes.

[0073] At the same time, when the rotating rod 202g rotates, it will simultaneously push the fixed rod 205b to move, and the movable strip 205a will move through the fixed rod 205b, so that the movable strip 205a drives the limiting strip 205c to engage with the positioning groove 204b-1, and the pressing rod 204b is locked through the cooperation between the two, so that it cannot move upward. In this way, it can be avoided that the pressing rod 204b moves upward during the dehydration process, which will cause the positioning sleeve 201f to drive the tooth plate 201c to engage with the limiting gear 201a. At the same time, the pressing strip 205d will press the inclined surface of the stressed block 205e, and the connecting sleeve 204e will move upward through the cooperation between the two, so that the bottom end of the connecting sleeve 204e is higher than the pressing block 204g. In this way, it can be avoided that the pressing block 204g will contact the connecting sleeve 204e when it moves.

[0074] When the dehydration is completed, the fork 107 is reset, the extension rod is separated from the rotating rod 202g, at this time, the rotating rod 202g is reset by the torsional spring 202i exerting a rotating force on the rotating rod 202g, and is separated from the connecting rod 202f and the fixed rod 205b, the support block 205g is pushed by the sixth spring 205h, and the movable strip 205a is reset by the support block 205g, so that the limiting strip 205c is separated from the positioning groove 204b-1, thereby releasing the restriction on the extrusion rod 204b, and at the same time, the extrusion strip 205d is separated from the stressed block 205e, and the connecting sleeve 204e is lowered to the initial position.

[0075] When the brake disc 104 rotates, the extrusion block 204g rotates and extrudes the connecting sleeve 204e through the extrusion block 204g, so that the connecting sleeve 204e drives the extrusion rod 204b to move upward, when the end surface of the extrusion rod 204b extrudes the push rod 204a, the push rod 204a is pushed to move and extrude the inner wall of the stressed groove 203a-1, so that the limiting block 203a is separated from the limiting groove 201f-1, and the restriction on the positioning sleeve 201f is released, so that the positioning sleeve 201f can drive the tooth plate 201c to move close to the limiting gear 201a, under the condition that the brake disc 104 rotates one circle, the positioning sleeve 201f moves a distance of one limiting groove 201f-1, with the rotation of the brake disc 104, after the brake disc 104 rotates a small number of circles, the limiting block 203a is engaged with another end limiting groove 201f-1, at this time, the tooth plate 201c is engaged with the limiting gear 201a, thereby locking the dehydration shaft 105, and the drum is stopped rotating in time, thereby avoiding the situation that the user accidentally clamps the hand when taking clothes, and avoiding the need for too much waiting time.
