Description

Technical Field

[0001] The present invention relates to a clutch speed change structure, a motor using the clutch speed change structure, a cooking utensil using the clutch speed change structure, an electrical appliance using the clutch speed change structure, and a clutch method. Background Art

[0002] Existing electrical appliances, such as cooking equipment, washing machines, hair dryers, etc., have different speed and torque requirements in different modes. In existing electrical appliances, when using direct motor output, electronic speed regulation is often adopted, resulting in extremely low output torque of the motor at low speed, which cannot drag heavy loads. The solution of configuring a gear speed change mechanism at the motor output end can achieve speed increase / deceleration, but because its transmission ratio is a fixed value, it cannot achieve the effect of taking into account both high and low speeds. The fixed transmission ratio can only be used in a single scenario, which cannot meet people's diverse usage needs. Summary of the Invention

[0003] The main purpose of the present invention is to provide a speed-changing clutch, which aims to realize different transmission ratios of the speed-changing clutch output to meet people's diverse usage needs.

[0077] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments. DETAILED DESCRIPTION

[0078] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0079] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0080] In addition, the descriptions of "first", "second", etc. in the present invention are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, "and / or" in the full text includes three solutions. Taking a and / or B as an example, it includes technical solution a, technical solution B, and technical solution that satisfies both a and B. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0081] In real life, people use wall breakers to make fluid drinks. Wall breakers use motors to drive processing actuators such as blades to operate at high speed to break the cell walls of ingredients, resulting in a fluid drink with a delicate taste. People also use noodle machines, in which the motor in the noodle machine drives the stirring rod to operate at a low speed to automatically knead dough. In this process, people face the following difficulties: wall breakers that operate at high speeds are often not suitable for heavy-load dough kneading functions. Or, when using wall breakers to whip more viscous ingredients, due to the existing mechanism, which usually uses electronic speed regulation, the output torque of the motor is extremely low at low speeds and is not smooth when running under heavy loads. Therefore, the whipping effect of viscous ingredients needs to be improved. In addition, because the functions of electrical appliances are relatively simple, in order to meet people's usage needs, people need many electrical appliances. In addition, for some solutions with added gear speed change mechanisms, although speed increase / deceleration can be achieved, the transmission ratio is a fixed value, which cannot achieve the effect of taking into account high and low speeds. Because we understand that for some food processing processes, high and low speed whipping will result in better mixing effect. Similarly, this applies not only to appliances that process food, but also to other appliances in daily life. For example, a washing machine often needs to drive the drum at different speeds to simulate the effect of rubbing clothes by hand to achieve better washing results. For example, a hair dryer also needs to alternate high and low wind speeds to simulate natural wind when blowing hair.

[0082] In order to solve the above problems and bring convenience to people's lives, the present invention provides a clutch transmission structure 1.

[0083] Please refer to Figures 1 to 3 In one embodiment, in order to achieve switching between different transmission speeds, the clutch transmission structure 1 of the present application includes an input shaft 20, an input rotor 30, an output shaft 40, an output rotor 50 and a driven member 60. The input rotor 30 is installed on the input shaft 20 and can rotate together with the input shaft 20 under the drive of the input shaft 20. The input rotor 30 can move on the input shaft 20, and the output rotor 50 can drive the output shaft 40 to rotate together with it.

[0084] In this embodiment, the clutch transmission structure 1 serves as a power transmission medium, outputting power from a power source through the output shaft 40 in various forms. Driven by the power source, when the input shaft 20 rotates in a first direction, the input rotor 30 and the output rotor 50 are drivingly coupled, causing the output shaft 40 to operate in a first state. When the input shaft 20 rotates in a direction opposite to the first direction, the input rotor 30 moves along the input shaft 20 to separate from the output rotor 50, and the input rotor 30 transmits power to the output rotor 50 via the driven member 60, causing the output shaft 40 to operate in a second state. In actual use, the output shaft 40's first state can be used to enable the same cooking appliance to operate in one functional mode while in another operating state. Alternatively, the clutch transmission structure 1 can be used to enable the output shaft 40 to alternate between the first and second operating states, thereby achieving another functional mode.

[0085] In this embodiment, the clutch transmission mechanism 1 can be incorporated into the internal structure of a cooking appliance or other electrical appliance. The input shaft 20, output shaft 40, and driven member 60 can be mounted on the housing of the cooking appliance or other electrical appliance, or can be arranged and integrated with the internal components of the cooking appliance or other electrical appliance. The input shaft 20, output shaft 40, output rotor 50, and driven member 60 can be mounted on different housing portions of the cooking appliance or other electrical appliance, or on the same housing. The output rotor 50 can be mounted on a rotating shaft distinct from the output shaft 40. This rotating shaft can be mounted on the housing of the cooking appliance or other electrical appliance in the same manner as the input shaft 20 and output shaft 40 described above, and can be mounted on the same housing as the multiple components, or on separate housings. The output rotor 50 and output shaft 40 can be connected by a transmission structure to enable them to rotate together. The transmission structure can include, but is not limited to, a gear transmission structure, a belt transmission structure, a sprocket transmission structure, and the like. The following content is described by assuming that the output rotary body 50 is installed on the output shaft 40 to make the clutch transmission structure 1 of the present application more compact.

[0086] Please refer again Figures 1 to 3In another embodiment, the clutch transmission structure 1 of the present application includes a housing 10, an input shaft 20, an input rotor 30, an output shaft 40, an output rotor 50 and a driven member 60. The input shaft 20 is rotatably connected to the housing 10, the input rotor 30 is mounted on the input shaft 20 and can rotate together with the input shaft 20 under the drive of the input shaft 20, and the input rotor 30 can move on the input shaft 20. The output shaft 40 is rotatably connected to the housing 10. In this embodiment, the output rotor 50 is mounted on the output shaft 40 and can drive the output shaft 40 to rotate therewith. The driven member 60 is connected to the housing 10 through a pivot 70.

[0087] In this embodiment, the housing 10 serves as the carrier of the entire structure of the clutch transmission structure 1. To facilitate the installation of its internal components, in one embodiment, the housing 10 includes a first shell 11 and a second shell 12 that are mutually covered and connected. The connection between the first shell 11 and the second shell 12 can be a method that allows for disassembly and separation without destroying the structure, such as a snap connection, a locking connection using connectors such as screws or bolts, etc., or a form that allows for separation when the structure needs to be destroyed, such as welding, a rotational connection on one side via a hinge, and a snap connection on the other side, etc. This application does not impose any restrictions on this. In addition, the material and shape of the first shell 11 and the second shell 12 can be sufficient as long as they meet the overall structural strength and can accommodate internal parts such as the input rotor 30 and the driven member 60. This application does not impose any restrictions on this. By configuring the housing 10 as a first housing 11 and a second housing 12, the present application allows the input shaft 20 to be rotatably mounted on the first housing 11, the output shaft 40 to be rotatably mounted on the second housing 12, and the follower 60 to be mounted on the first housing 11 or the second housing 12. After installing other parts, the two housings can be docked, making assembly more convenient. One end of each of the input shaft 20 and the output shaft 40 extends out of the housing 10 so as to be connected to external components. It is understandable that although the housing 10 shown in the figure is ultimately formed into a closed cavity structure, it is also feasible for it to adopt a hollow structure that can communicate with the outside world. Furthermore, in order to facilitate the installation of the clutch transmission structure 1 as a whole into the electrical appliance to which it is applied, in one embodiment, a connecting portion 13 is also provided on the housing 10. The connecting portion 13 may be located on the first shell 11 and / or the second shell 12. In one implementation, the connecting portion 13 is provided with a connecting hole, so that the clutch transmission structure 1 can be assembled as a whole into the internal environment of the electrical appliance to which it is applied by connecting parts such as screws or bolts.

[0088] In one embodiment, the input shaft 20, the output shaft 40, and the pivot 70 of the driven member 60 are connected to the housing 10 in a rotational manner. Bearings may be provided at the connection points between the input shaft 20, the output shaft 40, and the pivot 70 and the housing 10. The type of bearing is not limited in this application. Accordingly, a mounting groove structure capable of fixing the bearing is formed on the housing 10, such as 2 and Figure 3 As shown, a first bearing z1 is sleeved and fixed on the input shaft 20, a second bearing z2 is sleeved and fixed on the output shaft 40, and a third bearing z3 is sleeved and fixed on the pivot shaft 70. Furthermore, a first mounting groove 111, a second mounting groove 121, and a third mounting groove are formed on the housing 10 to respectively receive and fix the first bearing z1, the second bearing z2, and the third bearing z3. Thus, in the clutch transmission structure 1 of this embodiment, when driven by a power source, when the input shaft 20 rotates in a first direction, the input rotor 30 and the output rotor 50 are drivingly coupled, causing the output shaft 40 to operate in a first state. When the input shaft 20 rotates in a direction opposite to the first direction, the input rotor 30 moves along the input shaft 20 to separate from the output rotor 50, and the input rotor 30 transmits power to the output rotor 50 via the driven member 60, causing the output shaft 40 to operate in a second state. It can be understood that when the clutch transmission structure 1 is provided with a housing 10 so that it becomes a functional entity that can be disassembled and assembled separately, the input shaft 20, the output shaft 40 and the driven member 60 may not be directly connected to the housing 10 for rotation. In other settings, it is also possible to provide a mounting bracket structure connected to the housing 10, and at least one of the input shaft 20, the output shaft 40 and the driven member 60 may be connected to the mounting bracket for rotation.

[0089] That is, the above content introduces the clutch transmission structure 1 so that the output shaft 40 can output different transmission ratios or realize multiple modes in cooking utensils or other types of electrical appliances, and introduces the situation in which the clutch transmission structure 1 can be disassembled as a separate module, as well as another situation in which it is a part of a cooking utensils or other types of electrical appliances. The following content mainly further introduces the solution in which the clutch transmission structure 1 has a housing 10 that can be disassembled as a separate module.

[0090] The power source that can be combined with the input shaft 20 of the clutch transmission structure 1 of the present application can be a motor directly used for driving in an electrical appliance, and the input shaft 20 can be directly connected to the motor shaft of the motor, or the motor shaft of the motor forms the input shaft 20. The power source can also be a combination of a motor used for driving in an electrical appliance and a transmission structure similar to a belt, gear mechanism, sprocket, etc. connected to the motor shaft, and the input shaft 20 is combined with the transmission structure to realize power input. Please refer to Figure 3 and Figure 4The input rotor 30 of the present application moves along the input shaft 20 so that the input rotor 30 has two stop positions. When the input shaft 20 rotates in the first direction, please refer to Figure 3 , the input rotor 30 stays at the first position, and the input rotor 30 contacts and drives the driven member 60, so that the driven member 60 operates in the first state, wherein the first state includes multiple parameters of the output shaft 40, such as the speed, rotation direction, and output torque. When the input shaft 20 is driven by the power source to operate in a direction opposite to the first direction, please refer to Figure 4 , the input rotor 30 moves along the input shaft 20 and stays in the second position. In the second position, the input rotor 30 is separated from the output rotor 50, and the input rotor 30 transmits power to the output rotor 50 through the driven member 60, so that the output shaft 40 operates in the second state. At this time, the speed, rotation direction and torque of the output shaft 40 will be different from those in the first state. In one setting, the speed of the output shaft 40 when operating in the second state is lower than the speed when operating in the first operating state, and the torque when operating in the second state is greater than the torque when operating in the first operating state. Therefore, when the output shaft 40 operates in the second state, it outputs at a lower speed and a larger torque, which can be applied to scenes such as noodle making machines, and when switching between the first state and the second state for operation, due to the difference in speed and torque, it is particularly suitable for situations such as stirring and mixing during food processing, repeated kneading during washing in a washing machine, and alternating wind speeds to form a natural wind effect during the operation of a hair dryer.

[0091] Therefore, the technical solution of the present invention is to set the input rotor 30 in the clutch transmission structure 1 to be able to move along the input shaft 20. When the power source drives the input shaft 20 to rotate in a first direction, the input rotor 30 and the output rotor 50 realize transmission coupling so that the output shaft 40 operates in a first state. When the input shaft 20 moves in a second direction opposite to the first direction, the input rotor 30 is separated from the output rotor 50 by moving on the input shaft 20, and the input rotor 30 transmits power to the output rotor 50 through the driven member 60 to realize the output shaft 40 operating in the second state. In this way, the clutch transmission structure 1 of the present application has multiple output modes. In practical applications, when applied to electrical appliances, such as cooking utensils, the first state of the output shaft 40 can be a high-speed drive state, which meets the needs of, for example, whipping juice, and in the second operating state, it is a low-speed and high-torque state, which can meet heavy-load operating scenarios such as kneading noodles, thereby meeting people's demand for diversified use of electrical appliances. At the same time, the present application can also realize different speed ratio working states of switching the output speed, rotation direction and torque of the same appliance through the above design, so that the stirring and mixing effect can be better in the process of whipping and mixing ingredients, or the effect can be better in the work process of washing clothes, drying hair with air flow drive, etc.

[0092] To enable the input rotor 30 to move on the input shaft 20, in one embodiment, the clutch transmission structure 1 further includes a driving member (not shown) for driving the input rotor 30 to move on the input shaft 20. The driving member can have various structural forms. In one structural form, the driving member can be an electromagnet, which includes a first portion mounted on the input rotor 30 and a second portion mounted on the housing 10. When different currents are applied, the electromagnet generates forces in different directions to achieve repulsive and attractive effects on the input rotor 30, driving the input rotor 30 to move between a first position and a second position on the input shaft 20. It will be understood that in this structural configuration, the cross-sectional shape of the portion of the input shaft 20 where the input rotor 30 is mounted should limit the input rotor 30 to axial movement of the input shaft 20 and prevent the input rotor 30 from rotating circumferentially relative to the input shaft 20. To this end, the cross-sectional shape of the portion of the input shaft 20 where the input rotor 30 is mounted can be, for example, D-shaped, polygonal, or a special-shaped structure. In another structural form, the driving member can also be a lever structure installed on the housing 10. The lever structure has a driving end extending out of the housing 10 and an actuating end in contact with the input rotor 30. The user can manually press the driving end so that the lever structure transmits power to the actuating end in a lever-like manner and thereby drives the input rotor 30 to move along the input shaft 20. Of course, the power source of the driving end can also be provided by other electrical components, such as other motors, or cylinders. Similarly, when using a lever structure, the cross-sectional shape of the portion of the input shaft 20 where the input rotor 30 is installed should be such that the input rotor 30 can only move axially along the input shaft 20, and cannot rotate circumferentially relative to the input shaft 20. For specific methods, please refer to the above content and will not be repeated here. That is, the concept of this embodiment is to use a driving member as a third party to apply external force to drive the input rotor 30 along the axial direction of the input shaft 20. In this way, the stroke is easier to control. It can be understood that the form of the driving member of this application should not be limited to the two methods listed above. For example, a non-contact driving method or other feasible methods can be adopted, such as blowing the input rotor 30 along the input shaft 20 through airflow.

[0093] In order to realize the movement of the input rotary body 30 on the input shaft 20, in another embodiment, please refer to Figures 3 to 6One of the input shaft 20 and the input rotor 30 is formed with a spiral groove 21 extending in its axial direction, and the other is formed with a guide protrusion 34 adapted to be embedded in the spiral groove 21. The input rotor 30 is driven to move along the axial direction of the input shaft 20 through the interaction between the guide protrusion 34 and the spiral groove 21. In one setting, the spiral groove 21 is formed on the input shaft 20, and the guide protrusion 34 is formed on the inner wall of the input rotor 30, wherein the length of the spiral groove 21 extending in the axial direction of the input shaft 20 should be slightly greater than the distance from the first position to the second position, and the guide protrusion 34 is also spiral and has multiple sections. During operation, when the input shaft 20 rotates in the first direction, the driving force generated by the compression of the guide protrusion 34 and the wall of the spiral groove 21 drives the input rotor 30 to approach the output rotor 50 and reach the first position to realize the transmission coupling between the input rotor 30 and the output rotor 50. When the input shaft 20 rotates in a direction opposite to the first direction, the guide protrusion 34 generates a reverse force on the input rotor 30, causing the input rotor 30 to move from the first position to the second position, and then contact the follower 60 at this position and can transmit power to the output rotor 50. In this embodiment, the driving force of the input rotor 30 is achieved without the help of other external components, but is cleverly achieved by structural modifications on the input shaft 20 and the input rotor 30. Therefore, the number of parts is reduced, the cost is lowered, and the overall structure of the clutch transmission structure 1 is made smaller and more compact.

[0094] In an embodiment in which the input rotating body 30 is driven by the cooperation between the spiral groove 21 and the guide protrusion 34, to ensure the stability of the overall structure, in one embodiment, a first retaining structure 22 is further provided on the input shaft 20. The first retaining structure 22 is used to prevent the input rotating body 30 from rotating out of the spiral groove 21. In one structural form, the first retaining structure 22 is a retaining spring installed at the end of the input shaft 20 facing the output shaft 40, wherein the input shaft 20 can be provided with a retaining groove to retain the retaining spring. Furthermore, in order to prevent the input rotating body 30 from colliding with the housing 10 due to being rotated out of the range of the spiral groove 21 when moving on the input shaft 20, the first limiting structure 22 may also include another retaining spring arranged at the connection between the input shaft 20 and the housing 10 and close to the housing 10. The retaining spring can also be fixed by a retaining groove formed on the input shaft 20. It can be understood that the specific form of the first limiting structure 22 can also be other, such as a protruding structure formed on the input shaft 20. The protruding structure can be integrally formed with the input shaft 20, or fixed to the input shaft 20 by welding or the like, or detachably connected by threaded connection, plug-in or the like.

[0095] In this embodiment, to ensure stability during driving through the coordinated operation of the spiral groove 21 and the guide protrusion 34, the width of the spiral groove 21 is defined as t, and the axial extension height of the guide protrusion 34 in the input rotor 30 is defined as h, where h is no less than 1.5t. If the axial extension height of the guide protrusion 34 in the input rotor 30 is too small, the axial support force provided to the input rotor 30 will be too weak, which can easily lead to slippage or insufficient structural strength. Therefore, setting h to no less than 1.5t ensures stability during operation.

[0096] Please refer to Figure 3 and Figure 4 ,as well as Figures 6 to 8 In one embodiment, the input rotary body 30 includes a first base portion 31. The first base portion 31 can have various shapes. When the first base portion 31 is cylindrical, the first base portion 31 has a first end and a second end that are oppositely disposed. The first coupling portion 32 is disposed at the first end of the first base portion 31 facing the output shaft 40. The first transmission portion 33 is disposed on the outer side of the second section of the first base portion 31. The first base portion 31 is formed with an axial hole that passes through the first and second ends. The axial hole is used for the input shaft 20 to be inserted and installed. The guide protrusion 34 is formed on the inner wall of the axial hole. The first base portion 31, the first coupling portion 32, and the first transmission portion 33 can be a one-piece structure, or they can be separate structures and assembled and fixed together, or two of the three can be one-piece structures and assembled and fixed together.

[0097] The output rotor 50 includes a second base portion 51, a second coupling portion 52 disposed at one end of the second base portion 51 facing the input shaft 20, a second transmission portion 53 disposed on the outside of the second base portion 51, and the output shaft 40 is mounted through the second base portion 51. The second base portion 51, the second coupling portion 52, and the second transmission portion 53 of the output rotor 50 can be separate structures, or a single structure, or two of them can be a single structure and assembled together. Furthermore, the input rotor 30 and the output rotor 50 of the present application can have a regular, disc-like structure due to their three-part structure, or they can have an irregular, special-shaped structure.

[0098] The first coupling portion 32 and the second coupling portion 52 of the present application have various structural forms. In one setting, the first coupling portion 32 and the second coupling portion 52 are both one-way gear disc structures. In other settings, the first coupling portion 32 is a special-shaped groove structure formed by a depression on the end face of the first end, or the first coupling portion 32 is a threaded joint structure with an external thread formed on the outer wall surface of the first end, or the first coupling portion 32 is a plug joint structure with a plurality of protrusions protruding outward formed on the outer wall surface of the first end, and the second coupling portion 52 is a structure adapted to the first coupling portion 32.

[0099] Specifically, in order to achieve the above-mentioned output of the clutch transmission structure 1 in multiple modes and operating states with different transmission ratios, in one embodiment, the input rotor 30 has a first coupling portion 32 and a first transmission portion 33, and the output rotor 50 has a second coupling portion 52 and a second transmission portion 53. When the input shaft 20 rotates in a first direction driven by a power source, the first coupling portion 32 and the second coupling portion 52 are transmission-coupled. When the input shaft 20 rotates in a direction opposite to the first direction, the first coupling portion 32 and the second coupling portion 52 are disengaged, and the first transmission portion 33 and the second transmission portion 53 are transmission-coupled to different positions of the driven member 60, respectively, so that the output shaft 40 rotates in a second state.

[0100] In the case where there is only one follower 60, the follower 60 may include a third transmission part 61 and a fourth transmission part 62. When the input shaft 20 rotates in a direction opposite to the first direction, the first coupling part 32 and the second coupling part 52 disengage, and the first transmission part 33 contacts and drives the third transmission part 61, and the fourth transmission part 62 contacts and drives the second transmission part 53, so that the output shaft 40 rotates in the second state. Of course, when the output shaft 40 rotates in the second state in the solution of the present application, its speed and torque are also adjustable. Specifically, when there is only one follower 60, other transmission parts may be provided on the follower 60 between the third transmission part 61 and the fourth transmission part 62 or at other locations. Different speeds and torques can be output by the first transmission part 33 and the second transmission part 53 respectively transmitting and coupling to the other transmission parts of the follower 60.

[0101] In one embodiment, when the input shaft 20 rotates in a direction opposite to the first direction, the first coupling portion 32 and the second coupling portion 52 disengage, and the first transmission portion 33 and the second transmission portion 53 are respectively transmission-coupled to different positions of the driven member 60, so that the output shaft 40 rotates in the second state. The output rotor 50 can be fixed to the output shaft 40, that is, the output rotor 50 and the driven member 60 are always in a transmission-coupled state. When the input rotor 30 drives the output rotor 50 to rotate through the first coupling portion 32 and the second coupling portion 52, the driven member 60 also rotates idly. The movement of the input rotor 30 separates the output rotor 50 and couples the output rotor 50 to the driven member 60, thereby changing the power transmission path.

[0102] In order to reduce the load and improve energy efficiency, in another form, the output rotor 50 can be installed on the output shaft 40 and can also move along the output shaft 40. Thus, when the input shaft 20 rotates in the first direction, the input rotor 30 moves along the input shaft 20 toward the output rotor 50 to the first position to realize the transmission coupling between the first coupling part 32 and the second coupling part 52. And because the output rotor 50 is also a movable scheme, at this time both the input rotor 30 and the driven member 60 will be in a position not contacting the driven member 60. When the input shaft 20 rotates in a direction opposite to the first direction, the input rotor 30 moves from the first position to the second position and separates from the output rotor 50. The output rotor 50 also moves toward the input rotor 30 and contacts the driven member 60, so that the second transmission part 53 and the fourth transmission part 62 are transmission coupled. Specifically, as a way of implementing this embodiment, the output shaft 40 is provided with a guide portion 41, the output rotor 50 is provided with a guide hole, the guide portion 41 is penetrated by the guide hole, and the contour shape of the guide portion 41 and the guide hole is configured to limit the axial movement of the output rotor 50 along the output shaft 40; and the clutch transmission structure 1 also includes a reset member (80a, 80b), the reset member (80a, 80b) is used to drive the output rotor 50 to move along the output shaft 40 toward the input rotor 30. That is, when the input rotor 30 and the output rotor 50 are coupled via the first coupling portion 32 and the second coupling portion 52, the output rotor 50 is driven by the input rotor 30 to move a distance away from the input shaft 20, so that it is no longer in contact with the driven member 60, and the reset members (80a, 80b) are compressed. At the same time, when the input rotor 30 is separated, the reset members (80a, 80b) provide a driving force, causing the output rotor 50 to move toward the input shaft 20 and thus contact the fourth transmission portion 62 of the driven member 60. It is understood that when the output rotor 50 is not fixed to the output shaft 40, the output rotor 50 can also move on the rotating shaft on which it is mounted, and the above-mentioned drive scheme can also be adopted.

[0103] In some embodiments, the first transmission part 33, the second transmission part 53, the third transmission part 61, and the fourth transmission part 62 are all gear ring structures. Of course, the first transmission part 33, the second transmission part 53, the third transmission part 61, and the fourth transmission part 62 of the present application can also be selected as a friction cylinder structure. Among them, the gear meshing transmission method formed by the gear ring structure has the characteristics of structural stability and large load, and can be used as the preferred solution. Of course, the friction drive method of the friction cylinder structure makes the entire structure more simplified and easier to manufacture.

[0104] This application Figures 3 to 5 In the illustrated solution, the reset member (80a, 80b) is a spring or a spring sheet that provides elastic force, wherein the spring or spring sheet is disposed between the housing 10 and the second transmission member 50 and is in a compressed state. Figure 9 In the illustrated embodiment, the reset member 80b is a magnet that provides magnetic force. In the embodiment where the reset member 80b is a magnet, a first magnet and a second magnet may be provided on the housing 10 and the output rotor 50, respectively. The first magnet and the second magnet magnetically repel each other, so that the output rotor 50 always has a tendency to move along the output shaft 40 toward the input shaft 20.

[0105] Furthermore, to improve structural stability, the output shaft 40 is further provided with a second limiting structure 42, which is used to prevent the output rotary body 50 from separating from the output shaft 40. The second limiting structure 42 of the present application is provided at the end of the output shaft 40 facing the input shaft 20, wherein the specific form of the second limiting structure 42 can refer to the form of the first limiting structure 22 described above, and will not be repeated here.

[0106] In order to achieve a compact overall structure of the clutch transmission structure 1 and ensure that different parts do not interfere with each other during operation, when the first coupling part 32 and the second coupling part 52 are coupled in transmission, an axial spacing b is formed between the end of the first transmission part 33 away from the output shaft 40 and the end of the third transmission part 61 toward the output shaft 40, and an axial spacing c is formed between the end of the second transmission part 53 toward the input shaft 20 and the end of the fourth transmission part 62 away from the input shaft 20, and a spacing d is formed between the end faces of the input shaft 20 and the output shaft 40, wherein the spacing b and the spacing c are both not less than 0.3 mm, and the spacing d is not less than 0.2 mm. Since the input rotor 30 and the output rotor 50 are both axially movable, sufficient avoidance space is reserved through the above parameter design to avoid the possibility of collision, and the stability of the structure is higher.

[0107] In summary, the clutch transmission structure 1 proposed in this application has a housing 10, and the main structural forms formed include:

Then, when the input rotor 30 rises to the upper end of the input shaft 20 (in the posture shown in the figure), the input rotor 30 contacts the output rotor 50 fixedly mounted on the output shaft 40. At this time, the first coupling portion 32 on the input rotor 30 and the second coupling portion 52 on the output rotor 50 are transmission-coupled, so that the input shaft 20 directly drives the output shaft 40 to rotate, so that the output shaft 40 generates a first rotation. Working state. During this process, the output rotor 50 is always in a transmission coupling state with the driven member 60. At this time, the transmission member 60 is in an idling state. When the input shaft 20 rotates in the opposite direction, due to the interaction between the guide protrusion 34 and the spiral groove 21, the input rotor 30 is driven to descend from the upper end of the input shaft 20 (with the posture in the figure as a reference), and the input rotor 30 is driven to be transmission coupled with the driven member 60.

During this process, the output rotor 50 compresses the reset member 80a. When the input shaft 20 rotates in the opposite direction, due to the interaction between the guide protrusion 34 and the spiral groove 21, the input rotor 30 is driven to descend from the upper end of the input shaft 20 (with the posture in the figure as a reference), the input rotor 30 is separated from the output rotor 50, and the reset member 80a is elastically released to drive the output rotor 50 to move downward, thereby forming a state in which the first transmission part 31 on the input rotor 30 is transmission coupled with the third transmission part 61 on the driven member 60, and the second transmission part 53 on the output rotor 50 is transmission coupled with the fourth transmission part 62 on the driven member 60, thereby realizing the output of the output shaft 40 in the second state.

[0121] Structural form 7:

[0122] The clutch transmission structure 1 includes a casing 10, an input shaft 20, an input rotating body 30, an output shaft 40, an output rotating body 50 and a driven member 60. The input shaft 20 is rotatably connected to the first shell 11 of the casing 10 through a first bearing z1, and the input shaft 20 is rotatably connected to the second shell 12 of the casing 10 through a second bearing z2. The driven member 60 is fixed to the third bearing z3 through a pivot 70, and the third bearing z3 is fixed to the casing 10 for installation. The input rotor 30 interacts with the guide protrusion 34 formed on the inner wall of the axial hole of the first base 31 and the spiral groove 21 formed on the input shaft 20. When the input shaft 20 rotates in the first direction, the input rotor 30 is driven to move along the input shaft 20. Then, when the input rotor 30 rises to the upper end of the input shaft 20 (in the posture shown in the figure), the output rotor 50 is movably mounted on the output shaft 40, and a reset member 80b is provided between the output rotor 50 and the housing 10 to drive the output rotor 50 to have a downward movement trend.

The transmission coupling is performed so that the input shaft 20 directly drives the output shaft 40 to rotate, so that the output shaft 40 produces a first working state. During this process, the output rotor 50 compresses the reset member 80a. When the input shaft 20 rotates in the opposite direction, due to the interaction between the guide protrusion 34 and the spiral groove 21, the input rotor 30 is driven to descend from the upper end of the input shaft 20 (with the posture in the figure as a reference), the input rotor 30 is separated from the output rotor 50, and the reset member 80a is elastically released to drive the output rotor 50 to move downward, thus forming a state in which the first transmission part 31 on the input rotor 30 is transmission coupled with the third transmission part 61 on the driven member 60, and the second transmission part 53 on the output rotor 50 is transmission coupled with the fourth transmission part 62 on the driven member 60, thereby realizing the output of the output shaft 40 in the second state.

Figures 10 to 14 While two sub-followers are shown, in other embodiments, three, four, or more sub-followers may be provided to reduce the rotational speed and output greater torque. The follower 60 and the pivot 70 may be integral or separate structures. When the follower 60 and the pivot 70 are separate structures, keyways may be formed on both the follower 60 and the pivot 70, and the two may be bonded together via a connecting key. When the follower 60 and the pivot 70 are integral structures, they may be integrally formed by casting or fixed into an integral structure by welding.

[0126] The present application also constructs a clutch method through the above structure, which controls the input shaft to rotate in a first direction, so that the input rotor is transmission-coupled with the output rotor, and the output rotor drives the output shaft to operate in a first state;

[0127] The input shaft is controlled to rotate in a direction opposite to the first direction, causing the input rotor to move along the input shaft and separate from the output rotor. The input rotor then transmits power to the output rotor via the driven member, causing the output shaft to operate in the second state. This allows for multiple drive modes with different gear ratios within a single drive structure, better suiting various user needs.

[0128] Alternatively, the clutch method comprises the following steps:

[0129] The input shaft 20 is controlled to rotate in the first direction, so that the input rotor 30 transmits power to the output rotor 50 through the driven member 60 , and the output shaft 40 operates in the first state.

[0130] The input shaft 20 is controlled to rotate in a direction opposite to the first direction, so that the input rotor 30 moves along the input shaft 20 and is separated from the driven member 60 and coupled to the output rotor 50 . The output rotor 50 drives the output shaft 40 to operate in the second state.

[0131] Among them, the clutch method presented in this application can be to realize the clutch of the input rotor 30 and the output rotor 50 through the forward and reverse rotation of the motor in the electrical appliance so that the output shaft 40 outputs different states, wherein the logic of the clutch method can be combined with the control program of the motor in the working mode of the electrical appliance, thereby enabling the electrical appliance to realize different functions.

[0132] In one embodiment, the present application implements a clutch transmission structure 1 in another form to output different transmission ratios, wherein the clutch includes a housing 10, an input shaft 20, an input rotor 30, a tension mechanism, an output shaft 40 and an output rotor 50, the input shaft 20 is rotatably connected to the housing 10, the input rotor 30 includes a plurality of coupling parts arranged in a ring shape, the tension mechanism is used to connect the plurality of active coupling parts and the input shaft 20, and the tension mechanism is used to provide a driving force to gather the active coupling parts toward the input shaft 20, the output shaft 40 is rotatably connected to the housing 10, the output rotor 50 is installed on the output shaft 40 and can drive the output shaft 40 to rotate therewith, the output rotor 50 is provided with a multi-stage driven coupling part arranged axially and with varying diameters, and the driven coupling part surrounds the outside of the active coupling part.

[0133] Driven by the power source, when the input shaft 20 rotates at different speeds, the outer diameters of the rings formed by the multi-stage active couplings vary, allowing the multi-stage active couplings to selectively couple to one of the multi-stage driven couplings. Regarding the structure of the housing 10 and the installation of the input shaft 20 and output shaft 40 in this embodiment, please refer to the above description and will not be repeated here. The active coupling part can be in an arc shape. When the tension mechanism gathers the multiple sections of active coupling parts toward the input shaft 20 to the minimum outer diameter, the multiple sections of active coupling parts can form a ring shape that is connected end to end and surrounds the input shaft 20, while the output rotor 50 is constructed in a cylindrical shape. The driven coupling part is a multi-level annular step with different outer diameters formed on the inner wall surface of the output rotor 50. The tension mechanism can be constructed with multiple springs or hydraulic rods that can provide elastic contraction. During the rotation of the input shaft 20, due to the action of centrifugal force, the multiple sections of active coupling parts are driven to expand outward, and due to the different rotation speeds, the degree of outward expansion, that is, the outer diameter of the ring formed by the multiple sections of active coupling parts, is different, so that the multiple sections of active coupling parts contact different levels of driven coupling parts, so that the input rotor 30 drives the output rotor 50 to rotate. Among them, the transmission coupling method of the active coupling part and the driven coupling part can be a connection form of gear meshing, surface friction, pin and socket, which is not limited here. This embodiment can also enable the output shaft 40 to output outward at different speed ratios to meet different usage requirements.
