Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to a clutch device and household equipment. Background Technology

[0002] With the rapid development of automation and intelligence in household appliances, some existing household appliances include a cabinet, a door, an automatic door opening and closing device, and a controller. For example, a refrigerator with an automatic door opening and closing function has a door connected to the cabinet via an automatic door opening and closing device. This device is connected to and operates under the control of the controller, causing the door to automatically open or close relative to the cabinet. To allow users to freely choose between manual door opening and closing or using the automatic door opening and closing function, existing automatic door opening and closing devices include a clutch mechanism and a clutch actuator. The clutch actuator engages or disengages the clutch mechanism, allowing the drive component and actuator of the automatic door opening and closing device to be connected or disconnected, thus ensuring that the user's manual door opening and closing operation does not interfere with the automatic door opening and closing device.

[0003] However, the aforementioned clutch device requires a separate clutch actuator, which not only increases costs but also complicates the structure. Summary of the Invention

[0004] This application provides a clutch device and a household appliance to solve the technical problem that existing household appliances require a separate clutch actuator to achieve engagement or disengagement, which not only increases costs but also makes the structure complex.

[0005] To address the aforementioned technical problems, this application proposes a clutch device, comprising at least: a drive input component; a first transmission member connected to the drive input component; a second transmission member disposed within the first transmission member and meshing with the first inner sidewall of the first transmission member, wherein one end of the second transmission member is provided with a transmission portion; and an output member having a blocking groove at one end facing the second transmission member, wherein the transmission portion is releasably abutted against the blocking groove. When the clutch device performs an engagement action, the transmission portion abuts against the blocking groove; when the clutch device performs a disengagement action, the transmission portion disengages from the blocking groove.

[0006] The output component has at least a blocking part and an output groove at the end facing the second transmission component. The blocking part is disposed on the inner side wall of the output groove, and a blocking groove is formed between the blocking part and the inner side wall of the output groove.

[0007] The shape of the blocking groove is consistent with the shape of the motion trajectory of the transmission part.

[0008] It includes at least two second transmission components, the centers of which are distributed in a circle around the center of the first transmission component, and a first angle is formed between the centers of two adjacent second transmission components and the center of the first transmission component, and adjacent first angles are equal.

[0009] Among them, at least two transmission parts are distributed in a circle around the center of the first transmission component, and a second included angle is formed between the center of two adjacent transmission parts and the center of the first transmission component, and adjacent second included angles are equal.

[0010] The first transmission component includes a first transmission gear, and the second transmission component includes a second transmission gear. The number of first internal meshing teeth Z1 of the first transmission gear, the number of second external meshing teeth Z2 of the second transmission gear, and the number of second transmission gears n have the following relationship: the remainder of Z1 / n is zero; the remainder of (Z2-1) / n is zero.

[0011] It also includes at least a fixing member, which is located at the end of the second transmission member away from the transmission part and connected to the second transmission member; a damping force is formed between the fixing member and the output member.

[0012] The fixed component has a first fixed post at the end facing the second transmission component, and the output component has an output post at the end facing the fixed component. The output component is interference-fitted into the first fixed post.

[0013] It includes at least a second fixing post and a fixing cover. One end of the second fixing post is connected to the side of the fixing member facing the second transmission member, and the other end of the second fixing post extends out of the second transmission member. The fixing cover is connected to the other end of the second fixing post.

[0014] The first transmission component is flush with the end surface of the output component that is opposite to the output component, and the second transmission component is flush with the end surface of the output component that is opposite to the output component.

[0015] The first transmission component and the output component are coaxially arranged, the radius of the first transmission component is larger than the radius of the output component, and a support groove is recessed at the end of the first transmission component facing the output component.

[0016] The drive input component includes a drive component and a third transmission component. The drive component is connected to the third transmission component, and the third transmission component is engaged with the first transmission component.

[0017] The output component has a fourth transmission component on the side opposite to the first transmission component. The output component and the fourth transmission component are coaxially arranged, and the fourth transmission component is used to mesh with external components.

[0018] To solve the above-mentioned technical problems, this application proposes a household appliance, including: a cabinet; a door; and the aforementioned clutch device, wherein the clutch device is disposed between the cabinet and the door to allow the door to open or close relative to the cabinet.

[0019] This application's clutch device includes at least a drive input component, a first transmission component, a second transmission component, and an output component. The first transmission component is connected to the drive input component. The second transmission component is disposed within the first transmission component and engages with the first inner sidewall of the first transmission component. One end of the second transmission component has a transmission part. The end of the output component facing the second transmission component has a blocking groove. The transmission part can be disengaged from the blocking groove. When the clutch device performs an engagement action, the transmission part abuts against the blocking groove; when the clutch device performs a disengagement action, the transmission part disengages from the blocking groove. Firstly, through the mutual cooperation of the aforementioned drive input component, first transmission component, second transmission component, and output component, the clutch device automatically switches between engagement and disengagement actions, improving the stability and controllability of the clutch device during engagement and disengagement actions, and also increasing the success rate of disengagement actions. Secondly, the drive input component in the clutch mechanism not only engages the transmission part with the blocking groove but also disengages it. This means only one power source is needed for the drive input component to achieve both clutch engagement and disengagement, as well as drive the output component. This enhances the reusability of the drive input component, eliminating the need for a separate clutch actuator (such as an electromagnet), reducing production costs, and simplifying the structure. Furthermore, the second transmission component is positioned above the first, reducing the overall thickness of the clutch mechanism and resulting in a flatter structure suitable for equipment with limited installation space, such as household appliances.

Detailed Implementation

[0037] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0038] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0039] The clutch device and household appliances provided by the present invention will be described in detail below with reference to embodiments.

[0040] This application provides a clutch device. The clutch device can be installed between a first component (not shown in the figure) and a second component (not shown in the figure) for engaging and disengaging the first component and the second component. The first component may include at least one component. The second component may include at least one component. The first component and the second component may be, but are not limited to, a part of a household appliance (not shown in the figure), a part of a smart lock (not shown in the figure), or a part of a vehicle (not shown in the figure), etc. For example, the clutch device can be installed in a household appliance. Household appliances may include, but are not limited to, refrigerators, dishwashers, sterilizers, and cabinets, etc.

[0041] Please see Figures 1 to 3 , Figure 1 This is an exploded schematic diagram of an embodiment of the clutch device of this application; Figure 2 This is a schematic diagram of the structure of the second transmission component in the clutch device of this application; Figure 3 This is a schematic diagram of the output component in the clutch device of this application. In some embodiments, the clutch device 10 includes at least a drive input component (not shown in the figure), a first transmission component 11, a second transmission component 12, and an output component 14. The first transmission component 11 is connected to the drive input component. The drive input component can provide driving force and can serve as the overall power input for the clutch device 10.

[0042] The second transmission member 12 is disposed within the first transmission member 11. The number of second transmission members 12 may be, but is not limited to, two, three, or more than four. When there are multiple second transmission members 12, multiple second transmission members 12 are disposed within the first transmission member 11. The second transmission member 12 is engaged with the first inner sidewall 1111 of the first transmission member 11. When there are multiple second transmission members 12, at least two second transmission members 12 are engaged with the first inner sidewall 1111 of the first transmission member 11. When the drive input assembly drives the first transmission member 11 to rotate, due to the engagement between the first transmission member 11 and the second transmission member 12, the first transmission member 11 drives the second transmission member 12 to rotate.

[0043] The second transmission member 12 has a transmission part 122 at one end. The transmission part 122 is fixedly or detachably connected to one end of the second transmission member 12. In this embodiment, the transmission part 122 is integrally formed on one end of the second transmission member 12.

[0044] The output member 14 has a blocking groove 141 at one end facing the second transmission member 12. The transmission part 122 can be disengaged and abuts against the blocking groove 141. When the clutch device 10 performs a disengagement action, the transmission part 122 moves away from the blocking groove 141 and disengages from the blocking groove 141. Alternatively, when the clutch device 10 performs an engagement action, the transmission part 122 abuts against the blocking groove 141, and the transmission part 122 is used to transmit torque so that the transmission part 122 drives the output member 14 to rotate. The blocking groove 141 can be, but is not limited to, arc-shaped, elongated, etc., as long as it can satisfy the requirement that the transmission part 122 moves to the blocking groove 141 and abuts against the blocking groove 141, and its specific shape is not limited.

[0045] Please see Figure 4 and Figure 5 , Figure 4 This is a first partial schematic diagram of an embodiment of the clutch device of this application; Figure 5 yes Figure 4 The structural diagram shown in Figure A. Combined with... Figures 1 to 3 The clutch device 10 performs engagement and disengagement actions. When the clutch device 10 engages, the drive input assembly drives the first transmission member 11 to rotate in the forward direction around its center. The first transmission member 11 drives the second transmission member 12 to rotate in the forward direction, and the second transmission member 12 rotates around its own center. The transmission part 122 rotates with the second transmission member 12 into the blocking groove 141, and the transmission part 122 abuts against the blocking groove 141. At this time, the first transmission member 11, the second transmission member 12, and the output member 14 revolve around the aforementioned center.

[0046] When the clutch device 10 performs the disengagement action, the drive input component drives the first transmission component to rotate in the opposite direction along its center. The first transmission component 11 drives the second transmission component 12 to rotate in the opposite direction. The transmission part 122 rotates with the second transmission component 12 and disengages from the blocking groove 141. The transmission part 122 releases contact with the blocking groove 141, and then the drive input component stops working.

[0047] First, through the cooperation of the aforementioned drive input component, first transmission component 11, second transmission component 12, and output component 14, the clutch device 10 automatically switches between engagement and disengagement actions, improving the stability and controllability of the clutch device 10 during engagement and disengagement, while also increasing the success rate of disengagement. Second, the drive input component in the clutch device 10 not only allows the transmission part 122 to abut against the blocking groove 141, but also allows the transmission part 122 to disengage from the blocking groove 141. This means that only one power source is needed for the drive input component to achieve both engagement and disengagement of the clutch device 10 and to drive the output component 14, thereby improving the reusability of the drive input component and eliminating the need for a separate clutch actuator (such as an electromagnet), reducing production costs and simplifying the structure. Furthermore, the second transmission component 12, located within the first transmission component 11, reduces the overall thickness of the clutch device 10, resulting in a flatter structure that meets the requirements of devices with limited installation space, such as household appliances.

[0048] In some embodiments, at least a blocking portion 143 and an output groove 142 are provided at the end of the output member 14 facing the second transmission member 12. The blocking portion 143 is disposed on the inner sidewall of the output groove 142. That is, one end of the blocking portion 143 is disposed on the inner sidewall of the output groove 142 near the outer sidewall of the output member 14, and the other end of the blocking portion 143 extends away from the output groove 142 and near the inner sidewall of the outer sidewall of the output member 14. The number of blocking portions 143 may be, but is not limited to, two, three, four or more. The output groove 142 can accommodate the transmission member 122 and reduce rotational interference of the transmission member 122. The blocking groove 141 is formed between the blocking portion 143 and the inner sidewall of the output groove 142. The output groove 142 and the blocking groove 141 are connected. When the transmission member 122 rotates with the second transmission member 12, it rotates from the output groove 142 into the blocking groove 141. By cooperating with the aforementioned blocking part 143 and output groove 142, the aforementioned blocking groove 141 is formed, which facilitates the movement of the transmission part 122 into the blocking groove 141, thereby improving the stability and controllability of the engagement or disengagement action of the clutch device 10. Furthermore, the rotation of the transmission part 122 in the output groove 142 and blocking groove 141 reduces the overall thickness of the clutch device 10, making the clutch device 10 structure flatter and meeting the equipment requirements of smaller installation space.

[0049] Specifically, at least two blocking grooves 141 can be formed between the inner wall of the blocking part 143 and the output groove 142. For example, the transmission part 122 can be releasably abutted against one blocking groove 141 near one end of the blocking part 143; or, the transmission part 122 can be releasably abutted against another blocking groove 141 near the other end of the blocking part 143. By increasing the number of the above-mentioned blocking grooves 141, the requirement for the drive input component to rotate in at least two different directions can be met.

[0050] In one specific embodiment, the transmission part 122 can be releasably abutted against one end of a blocking groove 141 near the blocking part 143. Alternatively, the transmission part 122 can be releasably abutted against another blocking groove 141 near the other end of the blocking part 143. The transmission part 122 can have at least three states, such as the transmission part 122 being located in a blocking groove 141; or, the transmission part 122 being located in an output groove 142; or the transmission part 122 being located in another blocking groove 141. By controlling the drive input component to move along a first direction, the drive input component causes the transmission part 122 to enter a blocking groove 141; by controlling the drive input component to move along a second direction, the drive input component causes the transmission part 122 to disengage from a blocking groove 141 and enter an output groove 142, until the transmission part 122 reaches a rotation threshold, and then the drive input component is controlled to stop moving to prevent the transmission part 122 from continuing to move and rotating into another blocking groove 141. Alternatively, by controlling the drive input component to move along the second direction, the drive input component causes the transmission part 122 to enter another blocking groove 141; by controlling the drive input component to move along the first direction, the drive input component causes the transmission part 122 to disengage from the other blocking groove 141 and enter the output groove 142, until the transmission part 122 reaches another rotation threshold, and then the drive input component is controlled to stop moving to prevent the transmission part 122 from continuing to move and rotating into a blocking groove 141. The first direction and the second direction are opposite. One rotation threshold is the maximum angle of rotation of the transmission part 122 along the second direction, and the maximum angle can be, but is not limited to, 120°, etc., and is not limited here. The other rotation threshold is the maximum angle of rotation of the transmission part 122 along the first direction, and the maximum angle can be, but is not limited to, 120°, etc., and is not limited here.

[0051] The number of blocking portions 143 can be related to the number of transmission portions 122 and the number of second transmission members 12. For example, when there are two transmission portions 122 and two second transmission members 12, there can also be two blocking portions 143. Each blocking portion 143 has two blocking grooves 141 formed on both sides. When there are four transmission portions 122 and four second transmission members 12, there can also be four blocking portions 143, as in this embodiment. When there are multiple blocking portions 143, the multiple output grooves 142 can be connected to each other to facilitate the processing of the output member 14, etc.; or, the multiple output grooves 142 can be independently and separately arranged.

[0052] In some embodiments, the shape of the blocking groove 141 is consistent with the shape of the motion trajectory of the transmission part 122. During the rotation of the transmission part 122 along with the second transmission member 12, the transmission part 122 forms a motion trajectory. By defining the shape of the blocking groove 141 to match the shape of the motion trajectory of the transmission part 122, not only is it easier for the transmission part 122 to rotate into the blocking groove 141, reducing motion resistance, but it also improves the controllability of the engagement and disengagement of the clutch device 10.

[0053] Please see Figure 6 , Figure 6 This is a second partial schematic diagram of an embodiment of the clutch device of this application. (In conjunction with...) Figure 1 and Figure 4 In some embodiments, the clutch device 10 includes at least two second transmission members 12. The number of second transmission members 12 may be, but is not limited to, two, three, or more than four. At least two second transmission members 12 are disposed within the first transmission member 11. The centers of the at least two second transmission members 12 are circumferentially distributed around the center of the first transmission member 11. When the first transmission member 11 rotates, it can drive the at least two second transmission members 12 to rotate simultaneously, improving the stability and controllability of the clutch device 10's engagement and disengagement actions.

[0054] The centers of two adjacent second transmission components 12 and the center of the first transmission component 11 form a first included angle α. These adjacent first included angles α may be equal; or they may not be equal. Whether the adjacent first included angles α are equal can be determined according to actual needs.

[0055] In one specific embodiment, at least two second transmission members 12 are circumferentially distributed around the center of the first transmission member 11. A first angle α is formed between the centers of two adjacent second transmission members 12 and the center of the first transmission member 11. Adjacent first angles α are equal. By limiting adjacent first angles α to be equal, the consistency of the rotation of multiple transmission parts 122 into the blocking groove 141 is improved, thereby improving the stability and controllability of the engagement and disengagement actions of the clutch device 10.

[0056] For example, when there are two second transmission components 12, the angle between the center of the two second transmission components 12 and the center of the first transmission component 11 is 180 degrees, that is, the first included angle α is 180 degrees. This is because the two second transmission components 12 divide the first transmission component 11 into two first included angles α, both of which are 180 degrees.

[0057] When there are three second transmission components 12, a first included angle α is formed between the center of one second transmission component 12, the center of another second transmission component 12, and the center of the first transmission component 11; another first included angle α is formed between the center of one second transmission component 12, yet another second transmission component 12, and the center of the first transmission component 11; and yet another first included angle α is formed between the center of another second transmission component 12, yet another second transmission component 12, and the center of the first transmission component 11. The three second transmission components 12 divide the first transmission component 11 into three first included angles α, where the first included angle α, the second included angle α, and the yet another first included angle α are all equal and all 120 degrees. When there are four second transmission components 12, all four first included angles α are 90 degrees; when there are five second transmission components 12, all five first included angles α are 72 degrees; when there are six or more second transmission components 12, the six or more first included angles α can be deduced in the same way, and will not be elaborated here.

[0058] In another specific embodiment, at least two second transmission members 12 are circumferentially distributed around the center of the first transmission member 11. A first angle α is formed between the centers of two adjacent second transmission members 12 and the center of the first transmission member 11. Adjacent first angles α are not equal. Through this method, the clutch device 10 is engaged and disengaged.

[0059] For example, when there are two second transmission components 12, the angle between the centers of the two second transmission components 12 and the center of the first transmission component 11 can be 90 degrees and 270 degrees. Alternatively, the angle between the centers of the two second transmission components 12 and the center of the first transmission component 11 can be 30 degrees and 330 degrees. That is, the two second transmission components 12 divide the first transmission component 11 into two first angles α, and the two first angles α are not equal.

[0060] When there are three second transmission components 12, a first included angle α is formed between the center of one second transmission component 12, the center of another second transmission component 12, and the center of the first transmission component 11; another first included angle α is formed between the center of one second transmission component 12, yet another second transmission component 12, and the center of the first transmission component 11; and yet another first included angle α is formed between the center of another second transmission component 12, yet another second transmission component 12, and the center of the first transmission component 11. The three second transmission components 12 divide the first transmission component 11 into three first included angles α. For example, one first included angle α can be 90 degrees, another first included angle α can be 150 degrees, and yet another first included angle α can be 120 degrees, that is, the three first included angles α are all different. The aforementioned first included angle α, another first included angle α, and yet another first included angle α can also be other angles, which are not limited here. When there are four, five, or more second transmission components 12, the multiple first included angles α can all be different, which will not be elaborated here. Of course, in practice, at least two of the multiple first included angles α can be equal. For example, one first included angle α can be 90 degrees, another first included angle α can be 135 degrees, and yet another first included angle α can be 135 degrees. Or, one first included angle α can be 80 degrees, another first included angle α can be 140 degrees, and yet another first included angle α can be 140 degrees.

[0061] In some embodiments, at least two second transmission members 12 are circumferentially distributed around the center of the first transmission member 11. The first transmission member 11 is a first transmission gear 111. The second transmission members 12 are second transmission gears 121. Multiple second transmission gears 121 have the same radius. That is, multiple second transmission gears 121 simultaneously mesh with the first transmission gear 111, improving the stability and reliability of the clutch engagement and disengagement actions. In other embodiments, some second transmission gears 121 have the same radius, while others have different radii; that is, only some second transmission gears 121 mesh with the first transmission gear 111, achieving stability in the clutch engagement and disengagement actions.

[0062] In some embodiments, the number of transmission parts 122 corresponds to the number of second transmission members 12, and the number of transmission parts 122 may be, but is not limited to, two, three, or more than four. At least two transmission parts 122 are circumferentially distributed around the center of the first transmission member 11. When multiple second transmission members 12 rotate, multiple transmission parts 122 also rotate simultaneously, improving the stability and controllability of the clutch device 10.

[0063] A second included angle β is formed between the centers of the two adjacent transmission parts 122 and the center of the first transmission member 11. The adjacent second included angles β may be equal; or they may not be equal. Whether the adjacent second included angles β are equal can be determined according to the actual situation.

[0064] In one specific embodiment, at least two transmission parts 122 are circumferentially distributed around the center of the first transmission member 11. A second included angle β is formed between the centers of two adjacent transmission parts 122 and the center of the first transmission member 11. Adjacent second included angles β are equal. By limiting adjacent second included angles β to be equal, the consistency of multiple transmission parts 122 rotating simultaneously into the blocking groove 141 is improved, thereby enhancing the stability and controllability of the engagement and disengagement actions of the clutch device 10.

[0065] For example, when there are two second transmission members 12, there are two transmission parts 122. The angle between the center of the two transmission parts 122 and the center of the first transmission member 11 is 180 degrees, that is, the second included angle β is 180 degrees. Because the two transmission parts 122 divide the first transmission member 11 into two second included angles β, both of which are 180 degrees.

[0066] When there are three transmission parts 122, a second included angle β is formed between the center of one transmission part 122, the center of another transmission part 122, and the center of the first transmission member 11; another second included angle β is formed between the center of one transmission part 122, the center of yet another transmission part 122, and the center of the first transmission member 11; and yet another second included angle β is formed between the center of another transmission part 122, the center of yet another transmission part 122, and the center of the first transmission member 11. The three transmission parts 122 divide the first transmission member 11 into three second included angles β, and the first, second, and third included angles β are equal and all are 120 degrees. When there are four transmission parts 122, all four second included angles β are 90 degrees; when there are five transmission parts 122, all five second included angles β are 72 degrees; when there are six or more transmission parts 122, the six or more second included angles β can be deduced in the same way, and will not be repeated here.

[0067] In another specific embodiment, at least two transmission parts 122 are circumferentially distributed around the center of the first transmission member 11. A second included angle β is formed between the centers of two adjacent transmission parts 122 and the center of the first transmission member 11. Adjacent second included angles β are not equal. Through this method, the engagement and disengagement actions of the clutch device 10 are achieved. The principle of multiple adjacent second included angles β formed by multiple centers of transmission parts 122 and the center of the first transmission member 11 being unequal is similar to that of multiple adjacent second included angles β formed by multiple centers of second transmission members 12 and the center of the first transmission member 11 being unequal, and will not be described again here.

[0068] In some embodiments, the first transmission member 11 includes a first transmission gear 111. The first transmission gear 111 includes a first inner sidewall 1111. The first inner sidewall 1111 is provided with a first internal meshing tooth 11111. The second transmission member 12 includes a second transmission gear 121. The second transmission gear 121 includes a second outer sidewall 1211. The second outer sidewall 1211 is provided with a second external meshing tooth 12111. The second external meshing tooth 12111 and the first internal meshing tooth 11111 are meshed together. When the first transmission member 11 rotates, the first transmission member 11 drives the second transmission member 12 to rotate.

[0069] In some embodiments, the first transmission member 11 includes a first transmission gear 111. The second transmission member 12 includes a second transmission gear 121. The number of first internal meshing teeth Z1 of the first transmission gear 111, the number of second external meshing teeth Z2 of the second transmission gear 121, and the number of second transmission gears n have the following relationship: the remainder of Z1 / n is zero; the remainder of (Z2-1) / n is zero. By limiting the relationship between the number of first internal meshing teeth Z1 of the first transmission gear 111, the number of second external meshing teeth Z2 of the second transmission gear 121, and the number of second transmission gears n, multiple second transmission gears 121 can be meshed and connected within the first transmission gear 111, improving the transmission stability between the first transmission gear 111 and the second transmission gear 121, thereby improving the stability of the engagement and disengagement actions of the clutch device 10.

[0070] For example, the number of first internal meshing teeth Z1 of the first transmission gear 111 is 100, the number of second external meshing teeth Z2 of the second transmission gear 121 is 26, and the number of second transmission gears n is 5. That is, the remainder of 100 / 5 is 0; the remainder of (26-1) / 5 is 0. The number of first internal meshing teeth Z1 of the first transmission gear 111 is 100, the number of second external meshing teeth Z2 of the second transmission gear 121 is 21, and the number of second transmission gears n is 4. That is, the remainder of 100 / 4 is 0; the remainder of (21-1) / 5 is 0. Of course, the number of first internal meshing teeth Z1 of the first transmission gear 111, the number of second external meshing teeth Z2 of the second transmission gear 121, and the number of second transmission gears n can also be other values, which are not limited here.

[0071] Please see Figure 7 , Figure 8 as well as Figure 9 , Figure 7 This is a first structural schematic diagram of an embodiment of the clutch device of this application; Figure 8 yes Figure 7 The structural diagram shown in B; Figure 9 This is a cross-sectional schematic diagram of an embodiment of the clutch device of this application. (In conjunction with...) Figure 1In some embodiments, the clutch device 10 further includes at least a fixing member 13. The fixing member 13 is located at the end of the second transmission member 12 opposite to the transmission part 122. The fixing member 13 is connected to the second transmission member 12, serving to connect the second transmission member 12 to the fixing member 13. Additionally, a damping force is formed between the fixing member 13 and the output member 14. By providing the fixing member 13, not only is the second transmission member 12 installed, but a damping force is also formed between the fixing member 13 and the output member 14. When the drive input assembly drives the first transmission member 11 to rotate in the positive direction along its center, the first transmission member 11 drives the second transmission member 12 to rotate. Under the action of the damping force between the fixing member 13 and the output member 14, the fixing member 13 remains relatively stationary, while the second transmission member 12 rotates around its own center. The transmission part 122 rotates with the second transmission member 12 into the blocking groove 141, and the transmission part 122 abuts against the blocking groove 141. At this time, the first transmission member 11, the second transmission member 12, and the output member 14 revolve around the aforementioned center.

[0072] The aforementioned damping force can be achieved through structural means or by filling with a gel-like substance. Structural means can include, but are not limited to, interference fit connections, such as an interference fit connection between the fixing member 13 and the output member 14. Alternatively, a gel-like substance can be filled between the output member 14 and the fixing member 13. The gel-like substance can generate a certain damping force between the output member 14 and the fixing member 13. The gel-like substance can be, but is not limited to, lubricating oil.

[0073] Please see Figure 10 , Figure 10 This is a structural schematic diagram of the fixing component in the clutch device of this application. (Combined with...) Figure 1 , Figure 7 as well as Figure 9 Specifically, a first fixing post 131 is provided at one end of the fixing member 13 facing the second transmission member 12. The first fixing post 131 is detachably or fixedly connected to the fixing member 13. In this embodiment, the first fixing post 131 is integrally formed into the fixing member 13. An output post 144 is provided at one end of the output member 14 facing the fixing member 13. The output post 144 is detachably or fixedly connected to the output member 14. In this embodiment, the output post 144 is integrally formed into the output member 14. The output post 144 is interference-fitted into the first fixing post 131, which not only forms the aforementioned damping force between the output post 144 and the first fixing post 131, but also has a simple structure and is easy to implement; moreover, it can reduce the overall thickness of the clutch device 10, making the clutch device 10 structure flatter and able to meet the equipment requirements of smaller installation space.

[0074] Furthermore, the first fixing post 131 is provided with a first fixing hole 1311. The output post 144 is interference-fitted into the first fixing hole 1311 of the first fixing post 131. When the cross-sectional areas of the first fixing post 131, the first fixing hole 1311, and the output post 144 are all circular, the diameter of the first fixing hole 1311 is slightly smaller than the diameter of the output post 144, allowing the output post 144 to be interference-fitted into the first fixing hole 1311 to generate the aforementioned damping force.

[0075] Please see Figure 11 and Figure 12 , Figure 11 This is a schematic diagram of the first structure of the fixed cover in the clutch device of this application; Figure 12 This is a schematic diagram of the second structure of the fixed cover in the clutch device of this application. (Combined with...) Figure 1 , Figure 9 as well as Figure 10 In one specific embodiment, the clutch device 10 further includes at least a second fixing post 132 and a fixing cover 171. One end of the second fixing post 132 is connected to the side of the fixing member 13 facing the second transmission member 12. The second fixing post 132 is detachably or fixedly connected to the fixing member 13. As in this embodiment, the second fixing post 132 is integrally formed into the fixing member 13. The other end of the second fixing post 132 protrudes from the second transmission member 12. The fixing cover 171 is connected to the other end of the second fixing post 132. Through the cooperation of the second fixing post 132 and the fixing cover 171, not only is the installation of the second transmission member 12 realized, but the second transmission member 12 can also be rotated. At the same time, the structure is simple and easy to implement; at the same time, the overall thickness of the clutch device 10 can be reduced, making the clutch device 10 structure relatively flat, meeting the equipment requirements of smaller installation space.

[0076] The number of the second fixing posts 132 can be related to the number of the second transmission members 12. In this embodiment, for example, there are four second transmission members 12, and also four second fixing posts 132. The second fixing posts 132 are distributed circumferentially around the center of the first transmission member 11 on the fixing member 13. The first fixing post 131 is located at the center of the fixing member 13.

[0077] Furthermore, the second fixing post 132 is provided with a second fixing hole 1321. A fixing part 1711 is provided on one of the ends of the second fixing post 132 away from the fixing member 13 and the end of the fixing cover 171 facing the second fixing post 132. A fixing groove 1322 is provided on the other end of the second fixing post 132 away from the fixing member 13 and the end of the fixing cover 171 facing the second fixing post 132. The fixing part 1711 is inserted into the fixing groove 1322, and a connecting member (not shown in the figure) passes through the fixing part 1711, the fixing groove 1322, and the second fixing post 132, respectively, making the connection between the second fixing post 132 and the fixing cover 171 more stable, thereby improving the stability of the installation of the second transmission member 12. The connecting member can be, but is not limited to, connecting bolts and connecting screws. In this embodiment, the fixing groove 1322 is recessed at the end of the second fixing post 132 away from the fixing member 13. The fixing part 1711 protrudes from the fixing cover 171. When the fixing cover 171 is connected to the other end of the second fixing post 132, the fixing part 1711 is inserted into the fixing groove 1322.

[0078] In some embodiments, the end surface of the first transmission member 11 facing away from the output member 14 and the end surface of the second transmission member 12 facing away from the output member 14 are flush, which can reduce the overall thickness of the clutch device 10, making the overall structure of the clutch device 10 flatter and thus improving the applicability of the clutch device 10. In addition, when the clutch device 10 includes a fixing member 13, the end surface of the first transmission member 11 facing away from the output member 14 and the end surface of the second transmission member 12 facing away from the output member 14 are flush, which reduces the risk of the fixing member 13 colliding with the first transmission member 11 and thus improves the overall stability of the clutch device 10.

[0079] Please see Figure 13 , Figure 13 This is a structural schematic diagram of the first transmission component in the clutch device of this application. (Combined with...) Figure 1 as well as Figure 9 In some embodiments, the first transmission member 11 and the output member 14 are coaxially arranged, that is, the center of the first transmission member 11 and the center of the output member 14 are coaxially arranged. The radius of the first transmission member 11 is larger than the radius of the output member 14. A support groove 1113 is recessed at the end of the first transmission member 11 facing the output member 14. The support groove 1113 is used to connect with an external component (not shown in the figure), such as a first component or a second component. The support groove 1113 not only limits the rotation direction of the first transmission member 11, reducing the risk of the first transmission member 11 shifting in the front-back and left-right directions, but also supports the first transmission member 11. For example, the external component is provided with a support protrusion (not shown in the figure). The support protrusion is inserted into the support groove 1113, and the first transmission member 11 rotates relative to the external component. The first transmission member 11 mentioned above is a first transmission gear 111, wherein the support groove 1113 and the support protrusion can both be arranged in a ring shape.

[0080] Please see Figure 14 , Figure 14 This is a second structural schematic diagram of an embodiment of the clutch device of this application. (In conjunction with...) Figure 1 as well as Figure 7 In some embodiments, the drive input component is connected to the first transmission member 11. The drive input component and the first transmission member 11 can be connected, but are not limited to, meshing connection or direct motor drive connection. In one specific embodiment, the drive input component includes a drive member (not shown in the figure) and a third transmission member 15. The drive member is connected to the third transmission member 15 and is used for the overall power input of the clutch device 10. The drive member provides driving force to drive the third transmission member 15 to rotate forward or reverse. The third transmission member 15 is meshed with the first transmission member 11. Through the interaction of the drive member and the third transmission member 15, the transmission part 122 abuts against the blocking groove 141, and can also release the transmission part 122 from the blocking groove 141. That is, only one power source is needed for the drive input component to realize the engagement and disengagement of the clutch device 10 and drive the output member 14, thereby improving the reusability of the drive input component without the need for a separate clutch actuator (such as an electromagnet), reducing production costs and simplifying the structure. Furthermore, the third transmission component 15 is located on the outer periphery of the first transmission component 11 and meshes with it, which reduces the overall thickness of the clutch device 10, making its structure flatter and meeting the requirements for smaller installation space. The aforementioned driving component can be, but is not limited to, a drive motor (not shown in the figure). The drive motor performs less work during the disengagement process of the clutch device 10, thus reducing energy consumption. There can be multiple third transmission components 15. The third transmission component 15 can be, but is not limited to, an input gear (not shown in the figure). The input gear meshes with the first transmission gear 111.

[0081] Specifically, the third transmission member 15 and the first transmission member 11 are meshed together. The first transmission member 11 includes a first transmission gear 111. The first transmission gear 111 includes a first outer sidewall 1112. The first outer sidewall 1112 is provided with a first external meshing tooth 11121. The first outer sidewall 1112 is disposed opposite to the first inner sidewall 1111. The first transmission member 11 is meshed with the third transmission member 15 through the first external meshing tooth 11121.

[0082] Please see Figure 15 , Figure 15 This is a structural schematic diagram of the output component and the fourth transmission component in the clutch device of this application. (Combined with...) Figure 1 , Figure 9 as well as Figure 14In some embodiments, a fourth transmission member 16 is provided on the side of the output member 14 opposite to the first transmission member 11. The fourth transmission member 16 is detachably or fixedly connected to the side of the output member 14 opposite to the first transmission member 11. As in this embodiment, the fourth transmission member 16 is detachably connected to the side of the output member 14. The fourth transmission member 16 is coaxially arranged with the output member 14, that is, the center of the fourth transmission member 16 is coaxial with the center of the output member 14. The fourth transmission member 16 is used for meshing with external components, so that the power of the clutch device 10 is transmitted to the next-level external component through the fourth transmission member 16. The aforementioned fourth transmission member 16 may be, but is not limited to, an output gear (not shown in the figure).

[0083] In some embodiments, the centers of the first transmission member 11, the output member 14, and the fixing member 13 are all coaxially arranged. A plurality of second transmission members 12 are circumferentially distributed around the aforementioned centers.

[0084] In some embodiments, the output post 144 has an output hole 1441. The fourth transmission member 16 has a transmission hole 161. The output hole 1441 and the transmission hole 161 are stacked vertically and have the same size. The clutch device 10 also includes at least an output shaft (not shown in the figure). The output shaft passes through the output hole 1441 and the transmission hole 161 to allow the first transmission member 11, the output shaft, and the fourth transmission member 16 to rotate about the output shaft.

[0085] See Figures 1 to 15 This application provides a household appliance (not shown in the figure). The household appliance includes a housing (not shown in the figure), a door (not shown in the figure), and a clutch device. The clutch device 10 is disposed between the housing and the door to enable the door to automatically open or close relative to the housing. It should be noted that the clutch device 10 in this embodiment is the same as the clutch device 10 described in the above embodiments, and will not be repeated here.

[0086] In some embodiments, when the home appliance receives an automatic door opening / closing signal, the drive unit rotates forward, engaging the clutch device 10. The drive unit then causes the door to rotate automatically relative to the housing. After the automatic door opening / closing action is completed, the drive unit reverses, disengaging the clutch device 10, thereby breaking the transmission connection between the drive unit and the output device 14. When the user manually opens / closes the door, the home appliance does not receive the automatic door opening / closing signal, the clutch device 10 is disengaged, and the drive unit and output device 14 are not in a transmission connection state. When the user manually opens / closes the door, there is no transmission relationship between the actuator and drive unit of the automatic door opening / closing device; that is, automatic and manual door opening / closing do not affect each other, and the switching is stable. Users can freely choose between automatic and manual door opening / closing functions, improving user safety and convenience, and thus enhancing the user experience. Furthermore, when the home appliance experiences a power outage, the clutch device 10 is disengaged, allowing the user to manually open / close the door without being affected by the transmission components in the automatic door opening / closing device.

[0087] Therefore, by using the aforementioned clutch device 10, household appliances not only automatically switch between engagement and disengagement actions, improving the stability and controllability of the clutch device 10 during engagement and disengagement, but also require only one power source to drive the input component. This enables both the engagement and disengagement of the clutch device and the operation of the output component, thereby improving the reusability of the input component. Furthermore, it eliminates the need for a separate clutch actuator (such as an electromagnet), reducing production costs and simplifying the structure. Moreover, the second transmission component 12, positioned above the first transmission component 11, reduces the overall thickness of the clutch device 10, resulting in a flatter structure that meets the requirements of smaller installation spaces, such as household appliances where installation space is limited.

[0088] In some embodiments, the home appliance further includes a controller (not shown in the figure). The controller is connected to the clutch device 10. The controller receives user control commands and controls the clutch device 10 to perform engagement or disengagement actions, so that the door automatically opens and closes relative to the housing. The home appliance also includes a sensor (not shown in the figure). The sensor is used to sense the user's manual operation signal and send the sensing signal to the controller. The controller receives the sensing signal generated by the user's operation sensed by the sensor and controls the clutch device to disengage, so that the door stops rotating relative to the housing, thereby facilitating the user to manually open and close the door.
