[0002] With the acceleration of modern life rhythm and the continuous improvement of people's requirements for life quality, as a daily necessary electrical equipment for families, the performance and function diversity of washing machines gradually become the focus of consumers.

[0003] The traditional washing machine deceleration clutch, such as the full-automatic deceleration clutch, the hand-twisted deceleration clutch and the double-power deceleration clutch, although meets the basic washing and dewatering requirements to a certain extent, its design is often limited to a single input-output structure, that is, mainly through two output shafts to drive the pulsator and the dewatering tub respectively, to realize the basic functions of washing and dewatering. Therefore, although this design is classic and mature, it is single in function, lacks flexibility and expandability, and cannot meet the diversified needs of users when facing the growing personalized and intelligent needs.

[0004] With the complication of the internal structure of the washing machine, higher requirements are put forward for the support and fixation of parts. The traditional deceleration clutch often does not fully consider this point in the structural design, which leads to the problems of insufficient structural strength, poor stability, and insufficient internal space leading to the inability to expand functions when integrating more functional modules or improving the overall performance of the washing machine, and the problems of single washing mode and poor washing effect.

[0052] Example 1

[0053] To solve the above problems, such as Figures 1 to 11 As shown, this embodiment provides a tub assembly for a washing device, and a washing device having the tub assembly. This embodiment takes a washing machine as an example, including:

[0054] Outer bucket 2;

[0055] The inner tub 1 is rotatably disposed within the outer tub 2;

[0056] The motion conversion component 3 is located between the inner tub 1 and the outer tub 2 and is capable of relative rotation with the inner tub 1.

[0057] Washing auxiliary component 5 is movably mounted on inner tub 1;

[0058] The washing auxiliary component 5 works in conjunction with the motion conversion component 3 to convert the relative rotation of the motion conversion component 3 and the inner tub 1 into power to provide the washing auxiliary component 5 with the power to move on the inner tub 1.

[0059] In the above scheme, the coordinated movement of the inner tub 1, the motion conversion component 3, and the washing auxiliary component 5 are achieved through structural layout and transmission coordination, which effectively improves the washing effect.

[0060] In the present embodiment, the washing device has an outer tub 2, which can be made of high-strength PP material, having excellent impact resistance and aging resistance.

[0061] In the present embodiment, the washing device has an inner tub 1 rotatably arranged in the outer tub 2, which is used to place the washing clothes. The inner wall of the inner tub 1 is designed with a plurality of protruding water guide grooves, which not only enhance the water flow force in the washing process, but also effectively guide the sewage discharge and reduce the washing residue. The bottom of the inner tub 1 is designed to be flat and slightly inclined to the center, so as to form a strong water flow vortex when the pulsator 11 of the washing device rotates, thereby improving the washing efficiency.

[0062] In the present embodiment, the washing device has a driving device 4, which can drive the inner tub 1, the action conversion assembly 3 and the pulsator 11 to rotate.

[0063] In the present embodiment, the pulsator 11 is arranged at the center of the bottom of the inner tub 1, and the surface thereof is distributed with a plurality of protruding stirring blades, which can generate soft and powerful water flow when rotating, so as to not only penetrate the clothes fibers for deep cleaning, but also avoid clothes entanglement and damage. The center of the pulsator 11 is provided with a transmission shaft hole connected with the driving device 4, so as to ensure the accuracy and stability of power transmission.

[0064] In the present embodiment, the action conversion assembly 3 is arranged in the space between the inner tub 1 and the outer tub 2, and can rotate relative to the inner tub 1.

[0065] Specifically, the shape and size of the action conversion assembly 3 need to be designed according to the structure of the inner tub 1 and the outer tub 2, so as to ensure that it can be installed below the bottom of the inner tub 1 and has a certain strength and rigidity to withstand various forces and moments in the washing process.

[0066] In addition, the action conversion assembly 3 can also be designed to be strengthened as needed, such as increasing the reinforcing ribs, using more solid materials, etc., so as to improve the overall stability and durability thereof.

[0067] Further, the washing auxiliary assembly 5 is in transmission cooperation with the action conversion assembly 3, and converts the action of the relative rotation of the action conversion assembly 3 and the inner tub 1 into the power for the relative movement of the washing auxiliary assembly 5 on the inner tub 1.

[0068] Specifically, the washing auxiliary component 5 is the part of the washing equipment that directly participates in the washing action. This component is installed on the inner tub 1 and connected to the part of the motion conversion component 3 located on the outer periphery of the inner tub 1. When the motion conversion component 3 rotates under the drive of the drive device 4, the washing auxiliary component 5 moves up and down along the axial direction of the inner tub 1. This embodiment takes the up and down movement of the washing auxiliary component 5 as an example. A transmission mechanism can also be added to convert the action of driving the up and down movement of the washing auxiliary component 5 into the action of driving its rotation, such as rack and pinion transmission, or further adding a reversing transmission mechanism to achieve rotation in different directions.

[0069] The shape and size of the washing auxiliary component 5 need to be designed according to the diameter and height of the inner tub 1 and the washing requirements. Generally speaking, the washing auxiliary component 5 should have a certain degree of rigidity and toughness to maintain a stable shape during up-and-down movement and to effectively rub and beat the clothes.

[0070] In the above solution, since there is a transmission relationship between the motion conversion component 3 and the washing auxiliary component 5, dynamic adjustments can be made during the washing process to adapt to different clothes and washing needs, and the uniformity of washing can also be improved.

[0071] In this embodiment, the drive unit 4 is the power component of the entire washing equipment, which integrates the motor 44, reducer, transmission gear set and corresponding control circuit. The motor 44 outputs stable power through the reducer, and the transmission gear set is responsible for accurately distributing the power to the impeller 11, inner tub 1 and motion conversion component 3.

[0072] In the above scheme, during the washing process, the drive unit 4 drives the impeller 11, the inner tub 1, and the motion conversion component 3 to perform different forms of movement. The impeller 11 rotates at the bottom to generate a strong water flow, the inner tub 1 rotates to enhance the contact between the clothes and the water flow, and the motion conversion component 3 and the washing auxiliary component 5 utilize their special structures to collide and rub the clothes in the water flow, achieving a multi-layered cleaning effect. The three work together to complete the efficient washing task.

[0073] In the above solution, through ingenious structural design and innovative transmission mechanism, the coordinated movement of the inner tub 1, the impeller 11, and the motion conversion component 3 is achieved, significantly improving the washing effect. This component has a simple structure, is easy to maintain, and is inexpensive, possessing high market promotion value and application prospects.

[0074] In this embodiment, the washing equipment is further refined by introducing two specific operating states: a first operating state and a second operating state. These two states achieve different washing effects by adjusting the movement of the impeller 11, the inner tub 1, and the motion conversion component 3, thereby meeting the cleaning needs of clothes of different materials and degrees of soiling.

[0075] In this embodiment, the first working state is the washing state, in which the impeller 11 rotates relative to the inner tub 1, and the motion conversion component 3 rotates relative to the inner tub 1.

[0076] In one specific implementation, in the first working state, the impeller 11 rotates in the opposite direction to the inner tub 1, and the action conversion component 3 does not rotate.

[0077] Specifically, in the first working state, the drive device 4 controls the impeller 11 and the inner tub 1 to rotate in opposite directions. The impeller 11 rotates rapidly at the bottom, generating a strong agitation flow that impacts and scrubs the clothes; while the inner tub 1 rotates in the opposite direction, and the action conversion component 3 does not rotate, allowing the washing auxiliary component 5 to move up and down along the axis of the inner tub 1, forming a "washboard" effect that helps the clothes tumble and spread out inside the tub, avoiding tangling and localized wear.

[0078] The first working state is suitable for washing heavily soiled or heavy clothing, such as jeans and work clothes. By rotating the impeller 11 and the inner tub 1 in opposite directions, stains and stubborn dirt on the surface of the clothes can be removed more effectively, while reducing damage to the clothes.

[0079] In this embodiment, the second working state is that the impeller 11, the inner barrel 1, and the motion conversion component 3 move synchronously.

[0080] In one specific implementation, in the second working state, which is the dehydration state, the drive device 4 controls the impeller 11, the inner tub 1, and the motion conversion component 3 to rotate synchronously at the same speed. Due to the centrifugal force acting on the clothes, the aforementioned dehydration process is achieved.

[0081] In the above solution, the washing equipment achieves diversification and refinement of the washing process by introducing a first working state and a second working state. Users can select the appropriate washing mode according to the material of the clothes, the degree of soiling, and washing needs, thereby achieving the best washing results. This design not only improves the flexibility and practicality of the washing equipment.

[0082] Example 2

[0083] This embodiment is a further description of Embodiment 1 described above.

[0084] like Figures 1 to 11 As shown, in this embodiment, the motion conversion component 3 is sleeved on the outer periphery of the inner tub 1 and has a circumferential power steering mechanism that cooperates with the washing auxiliary component 5, which is used to convert the circumferential relative rotation power into the power for the washing auxiliary component 5 to move along the axial direction of the inner tub 1.

[0085] In this embodiment, the motion conversion component 3 includes a connecting part 31, which is disposed between the bottom of the inner tub 1 and the bottom of the outer tub 2 and is connected to the driving device 4.

[0086] Furthermore, the motion conversion component 3 includes a mating part 32 connected to the connecting part 31, extending between the inner barrel 1 peripheral wall and the outer barrel 2 peripheral wall, and the extended end of the mating part 32 forms the power steering mechanism.

[0087] Furthermore, the power steering mechanism is a support surface 321 that is continuously arranged in the circumferential direction and has a height variation. The support surface 321 is slidably supported and engaged with the bottom end of the washing auxiliary component 5.

[0088] Furthermore, the connecting part 31 is fitted onto the second output shaft 412 of the drive device 4; the mating part 32 extends horizontally from the outer periphery of the connecting part 31 toward the outer periphery of the inner barrel 1, and then bends upward in the outer periphery area at the bottom of the inner barrel 1, with its extended ends arranged alternately at different heights along the circumferential direction to form the support surface 321.

[0089] Specifically, the main function of the washing auxiliary component 5 is to rotate along its wavy support surface 321 as the motion conversion component 3 rotates. Due to the interaction of the wavy surfaces of the motion conversion component 3, certain parts of the washing auxiliary component 5 (usually the parts that are in direct contact with the clothes) can move up and down along the axis of the inner tub 1. This combined motion can more effectively tumble and knead the clothes, improving the washing effect.

[0090] Furthermore, the mating part 32 is provided with a plurality of spaced-apart through holes 33. Specifically, the mating part 32 is provided with multiple spaced-apart through holes 33, and the opening area of ​​the through holes 33 can be adjusted as needed. Providing through holes 33 can effectively reduce the overall weight of the motion conversion component 3, thereby effectively controlling the overall weight of the washing equipment and simultaneously reducing manufacturing costs.

[0091] Preferably, the washing auxiliary component 5 extends along the axial direction of the inner tub 1.

[0092] Specifically, the washing auxiliary component 5 extends vertically along the axis of the inner tub 1. This design allows the washing auxiliary component 5 to fully cover the clothes inside the inner tub 1 when it moves up and down, thereby achieving a more uniform washing effect.

[0093] In this embodiment, the second output shaft 412 begins to rotate, driving the connecting part 31 to rotate. The wave-shaped support surface 321 provided on the mating part 32 guides the washing auxiliary component 5 to rotate and move up and down with the inner tub 1 through a sliding connection. This movement mode allows the washing auxiliary component 5 to contact the clothes in a very flexible and efficient manner, achieving an all-around washing effect. At the same time, because the washing auxiliary component 5 moves up and down along the axial direction of the inner tub 1, the clothes can be more thoroughly tumbled and rubbed during the washing process, thereby improving the uniformity and cleanliness of the washing.

[0094] In this embodiment, the washing auxiliary component 5 has a sliding plate 51, which is movably mounted on the inner side of the peripheral wall of the inner tub 1.

[0095] Furthermore, to enhance the washing effect, the surface of the skateboard 51 can also be designed with raised or recessed structures to increase the contact area and friction with the clothes.

[0096] Furthermore, the washing auxiliary component 5 has a support member 50, which is installed on the outside of the inner tub 1, passes through the inner tub 1 and is connected to the slide plate 51. The bottom end of the support member 50 is slidably engaged with the power steering mechanism in the circumferential direction.

[0097] Specifically, when the connecting part 31 rotates with the second output shaft 412, it drives the support member 50 to slide on the mating part 32. Since the support surface 321 of the mating part 32 is wavy, the support member 50 drives the slide plate 51 to move up and down along the axis of the inner tub 1, so as to stir or wash the clothes in the inner tub 1.

[0098] In this embodiment, the support component 50 has a limiting plate 53 installed on the outer side of the inner barrel 1 peripheral wall.

[0099] Furthermore, the inner barrel 1 has a limiting hole 12 on its peripheral wall, and the limiting plate 53 is connected to the sliding plate 51 by a connector that can move up and down through the limiting hole 12.

[0100] Furthermore, a mounting hole with a smaller opening size is provided below the limiting hole 12, and the limiting plate 53 is fixedly installed on the inner barrel 1 through the mounting hole.

[0101] Specifically, the main function of the limiting plate 53 is to provide additional stability and guidance. By mounting the slide plate 51 on the limiting plate 53, it can be ensured that the slide plate 51 maintains the correct orientation and position during movement, avoiding deviation from the track or unnecessary vibration.

[0102] Furthermore, by setting the limit plate 53 and the slide plate 51 to be connected and partially inserted into the limit hole 12, the movement range of the limit plate 53 and the slide plate 51 is limited, ensuring that they can only move within the predetermined track, thereby improving the stability and reliability of the entire system.

[0103] In one specific embodiment, the slide plate 51 is provided with a screw post that passes through the limiting hole 12, and the screw post can move up and down within the limiting hole 12. The screw passes through the through hole on the limiting plate 53 and is screwed into the screw post, connecting the limiting plate 53 and the slide plate 51 within the limiting hole 12, thereby achieving the assembly of the two.

[0104] In this embodiment, the support component 50 has a support rod 52, which is connected to the limiting plate 53.

[0105] Furthermore, the support component 50 has a pulley 54 mounted on the bottom end of the support rod 52, which rolls along the support surface 321. Specifically, the use of the pulley 54 significantly reduces the friction between the support rod 52 and the support surface 321, allowing the washing auxiliary assembly 5 to move more smoothly. This not only improves the system's operating efficiency but also reduces wear and noise.

[0106] In this embodiment, the bottom of the support rod 52 is provided with an inverted U-shaped groove, and the pulley 54 is embedded in the inverted U-shaped groove. Specifically, the design of the inverted U-shaped groove provides a stable installation position and guidance for the pulley 54. This structure ensures that the pulley 54 can maintain the correct direction and position during movement, avoiding the risk of displacement or detachment.

[0107] In this embodiment, the washing auxiliary component 5 has a compression spring 55 disposed on the upper part of the support rod 52, with one end abutting against the support rod 52 and the other end abutting against the limiting plate 53. Specifically, the pressure of the compression spring 55 can also help overcome the resistance that the washing auxiliary component 5 may encounter during its movement.

[0108] In this embodiment, the washing auxiliary component 5 has a tension spring 56 disposed at the lower part of the support rod 52, with one end installed at the bottom end of the limiting plate 53 and the other end installed at the bottom end of the support rod 52. The tension spring 56 serves as a buffer and adjustment mechanism. When the support rod 52 and the sliding plate 51 move upward, the tension spring 56 is stretched to deform, thereby reducing the excessive pressure on the compression spring 55 and providing a certain elastic restoring force when needed.

[0109] Preferably, the maximum rebound force provided by the compression spring 55 is greater than the maximum tension provided by the tension spring 56. Since the pressure of the compression spring 55 is designed to be greater than the maximum effective force of the tension spring 56, the main function of the tension spring 56 is to assist in adjusting rather than to dominate the movement of the washing auxiliary component 5.

[0110] In this embodiment, the limiting plate 53 has a hollow channel, and the support rod 52 extends into the channel to achieve the assembly of the two.

[0111] Furthermore, the compression spring 55 is disposed at the top of the channel of the limiting plate 53, with one end abutting against the top wall of the channel and the other end abutting against the top of the support rod 52 extending into the channel. When the support rod 52 moves upward, the compression spring 55 is compressed and deformed.

[0112] Furthermore, the washing auxiliary component 5 is provided with at least two tension springs 56, which are respectively disposed on both sides of the support rod 52, with one end connected to the bottom end of the limiting plate 53 and the other end connected to the bottom end of the support rod 52.

[0113] In the above scheme, by reducing friction, providing guidance, applying pressure and buffering adjustment, it is ensured that the washing auxiliary component 5 can complete its predetermined movement trajectory more smoothly and accurately.

[0114] Example 3

[0115] This embodiment is a further description of the above embodiments one and two.

[0116] like Figures 7 to 11 As shown, in this embodiment, the drive device 4 has a power output component 41. One end of the power output component 41 is designed with a structure having multiple transmission interfaces so as to be connected to the motion conversion component 3, the impeller 11 and the inner barrel 1 respectively.

[0117] In a further embodiment, the power output component 41 includes a third output shaft 413 connected to the impeller 11, a first output shaft 411 connected to the inner barrel 1, and a second output shaft 412 connected to the motion conversion component 3.

[0118] Furthermore, the second output shaft 412 is sleeved on the outer periphery of the first output shaft 411, and in the first working state, the second output shaft 412 is braked in the circumferential direction.

[0119] Specifically, the third output shaft 413, as the core component for power output, passes directly through the bottom of the inner barrel 1 and connects to the impeller 11. It is responsible for transmitting the power generated by the drive unit 4 to the impeller 11, driving the impeller 11 to rotate. The design of the third output shaft 413 must consider sufficient strength and rigidity to ensure that it will not deform or break during high-speed rotation.

[0120] The first output shaft 411 is sleeved around the outer periphery of the third output shaft 413 and connected to the bottom of the inner barrel 1. This nested design not only saves space but also makes the transmission structure more compact. The design of the first output shaft 411 must ensure smooth and interference-free relative movement with the third output shaft 413, while also transmitting sufficient power to the inner barrel 1 to achieve rotation or swaying of the inner barrel 1.

[0121] The second output shaft 412 is further sleeved around the outer periphery of the first output shaft 411 and connected to the motion conversion assembly 3. It is responsible for transmitting power to the washing auxiliary assembly 5, driving it to move up and down to enhance the washing effect.

[0122] In a preferred embodiment of this invention, precision bearings 47 are used between the third output shaft 413, the first output shaft 411, and the second output shaft 412 to ensure smooth and stable relative movement between them. Furthermore, to further improve transmission efficiency, gear sets or other gear train mechanisms can be installed between the output shafts to achieve efficient power distribution and transmission.

[0123] In addition, for ease of installation and maintenance, the ends of each output shaft can be designed with connectors or fixing devices that are easy to disassemble and install.

[0124] In the above solution, by introducing a multi-layer nested output shaft design, precise transmission control of the impeller 11, inner tub 1, and motion conversion component 3 was successfully achieved. This design not only simplifies the transmission structure and improves transmission efficiency, but also enhances the overall performance and reliability of the washing equipment. At the same time, it also provides convenient conditions for subsequent maintenance and upgrades.

[0125] In a further embodiment, the top end of the third output shaft 413 extends beyond the top end of the first output shaft 411 and passes through the central region of the bottom of the inner barrel 1 to connect with the impeller 11. This design ensures that the impeller 11 can receive the most direct and stable power input, thereby achieving efficient rotational motion.

[0126] Furthermore, the top end of the first output shaft 411 extends beyond the top end of the second output shaft 412, and the center of the bottom of the inner barrel 1 is fitted onto the upper part of the first output shaft 411, achieving a stable connection with the inner barrel 1 to drive the inner barrel 1 to perform corresponding movements. The top end of the first output shaft 411 extends beyond the top end of the second output shaft 412, providing installation space for the second output shaft 412.

[0127] Furthermore, the motion conversion component 3 has a connecting part 31 fitted onto the upper part of the second output shaft 412. This arrangement allows the second output shaft 412 to cooperate with the first output shaft 411, enabling the washing auxiliary component 5 to move relative to the inner tub 1, thereby enhancing the washing effect.

[0128] Furthermore, there are gaps between the third output shaft 413 and the first output shaft 411, and between the first output shaft 411 and the second output shaft 412.

[0129] Specifically, in order to reduce friction and energy loss between the output shafts and ensure the stability of the transmission system, gaps are provided between the third output shaft 413 and the first output shaft 411, and between the first output shaft 411 and the second output shaft 412. These gaps can be adjusted according to actual needs to ensure that the output shafts can move smoothly relative to each other.

[0130] Furthermore, a sealing component 42 is provided within the interval. Specifically, to prevent liquids such as water and detergent from seeping into the transmission system and causing damage to components or transmission failure, a sealing component 42 is added to form an effective sealing barrier. In addition, considering that the second output shaft 412 needs to pass through the bottom of the outer tub 2 to connect with the motion conversion assembly 3, another sealing component 42 is provided on the outer periphery of the second output shaft 412 to ensure complete isolation between the inside of the inner tub 1 and the transmission system.

[0131] In the above solution, the transmission efficiency and sealing performance of the washing equipment are significantly improved through the detailed layout of the multi-layer nested output shaft and the addition of sealing component 42. This design not only extends the service life of the transmission system but also ensures the cleanliness and dryness of the internal environment of the washing equipment, providing users with a more reliable and efficient washing experience.

[0132] In this embodiment, the drive device 4 also includes an input shaft 43, an input shaft sleeve 431, a torque shaft sleeve 433, a clutch mechanism, a lower end shell 49 and an upper end shell 48, a braking mechanism 45, a wheel system component 46, a brake mechanism, a bearing 47 and a water seal.

[0133] Specifically, input shaft 43 receives power input from motor 44. Input shaft sleeve 431 is fitted onto input shaft 43 to protect input shaft 43 and transmit power. Torque sleeve 433 cooperates with input shaft sleeve 431 to transmit torque to subsequent components. Clutch mechanism controls power transmission between different components, enabling switching between washing and spin-drying modes. Lower end shell 49 and upper end shell 48 constitute the outer housing of clutch mechanism and the entire drive unit 4, protecting internal components. In washing mode, the brake wheel of braking mechanism 45 is gripped by brake band to prevent rotation of the fixed shaft. Gear train component 46 consists of multiple gears, enabling power transmission and speed change between different shafts. Braking mechanism includes components such as brake band, used to control the gripping and releasing of brake wheel. Bearing 47 and water seal are used to ensure the stability and sealing of each shaft during rotation.

[0134] In this embodiment, when the drive device 4 enters the washing mode, the motor 44 transmits power to the clutch mechanism via the input shaft 43. The clutch mechanism controls the third output shaft 413 and the first output shaft 411 to rotate in opposite directions, and the third output shaft 413 drives the impeller 11 to rotate. At the same time, the clamping of the brake wheel in the braking mechanism prevents the rotation of the second output shaft 412, so that the action conversion component 3 does not rotate, thereby allowing the washing auxiliary component 5 to move up and down, thereby rubbing and agitating the clothes.

[0135] When the spin-drying mode is needed, the motor 44 continues to transmit power to the clutch mechanism via the input shaft 43, and then to the third output shaft 413, the first output shaft 411, and the second output shaft 412 via the gear train component 46. The three rotate synchronously, driving the washing tub and other components to rotate at high speed, using centrifugal force to shake out the water from the clothes, thus achieving the spin-drying function.

[0136] In one embodiment, the input shaft 43 receives rotational power from an external power source. A torque sleeve 433 enhances the connection between the input shaft 43 and adjacent components or transmits greater torque. An input sleeve 431 supports other components on the input shaft 43, such as the input shaft center gear 432, and provides axial positioning. A clutch sleeve 434 is used in conjunction with a clutch. A one-way bearing 471 allows free rotation in a specific direction and locks in the opposite direction, used to implement specific transmission logic or protection mechanisms. An oil-impregnated bearing 472 reduces friction and wear, improves transmission efficiency, and may be used to support certain rotating components. The input shaft center gear 432 rotates coaxially with the input shaft 43, serving as the first transmission element for power input. The output shaft center gear 465a is typically connected to the output shaft, receives power transmitted via a planetary gear set, and ultimately outputs the power. Lower coaxial planetary gear 462a, upper lower coaxial planetary gear 461a, lower upper coaxial planetary gear 464a, and upper upper coaxial planetary gear 463a: These planetary gears are mounted on the planet carrier, rotate around the central gear, and transmit power by meshing with other planetary gears or the external ring gear. External ring gear 466a: Meets with the planetary gears; its direction of rotation and speed depend on the arrangement and transmission ratio of the planetary gears. Third output shaft 413, first output shaft 411, and second output shaft 412: Receive power from the gear train and transmit it to different mechanical components. These output shafts may achieve different speeds and torques through different gear combinations.

[0137] When the input shaft 43 rotates, the central gear 432 of the input shaft begins to rotate, driving the planetary gear set that meshes with it. The gears in the planetary gear set revolve around the central gear while rotating on their own axes, transmitting power through the external gear ring 466a or through meshing with each other. Depending on the configuration and gear ratio of the planetary gear set, the power is distributed to different paths and may undergo further changes in speed and torque through multiple stages of transmission. Ultimately, the power is output through different output shafts (third output shaft 413, first output shaft 411, second output shaft 412), each potentially possessing different speed and torque characteristics to meet the needs of different mechanical components.

[0138] In another embodiment, the lower coaxial planetary gear 462b and the upper coaxial planetary gear 461a are mounted on the planetary gear carrier and rotate around the central gear 432 of the input shaft, simultaneously meshing with the upper internal gear ring 463b and the lower internal gear ring 464b. The rotation and revolution of these planetary gears together achieve the splitting and transmission of power. The upper internal gear ring 463b and the lower internal gear ring 464b are located above and below the planetary gear set, respectively, meshing with the coaxial planetary gears and converting the rotation of the planetary gears into specific output motion. These gear rings can be fixed or rotating, depending on the design requirements of the gear train.

[0139] In another embodiment, the gear train component 46 provided in this embodiment includes a lower planetary gear 462c and an upper planetary gear 461c: mounted on the planetary gear carrier, rotating around the input shaft center gear 432, and meshing with the internal gear ring 463c and the external gear ring 464c to achieve power splitting and transmission. The internal gear ring 463c and the external gear ring 464c: located inside and outside the planetary gear set respectively, meshing with the planetary gears, converting the rotation of the planetary gears into specific output motion. The third output shaft 413, the first output shaft 411, and the second output shaft 412: receive power from the gear train and transmit it to different mechanical components. These output shafts may obtain different speeds and torques through different gear combinations. The planetary gear cover 465c: encloses the planetary gear set, protecting the internal gears from contamination and damage, and may also serve to support and position the planetary gear carrier. The gear train housing cover: covers the entire gear train housing and provides necessary sealing and support.
