Description

Technical Field

[0001] The utility model relates to the technical field of cleaning robots, and specifically, to a swing transmission device and a cleaning device. Background Art

[0002] In order to improve the cleaning effect of the cleaning robot at the corners, it is necessary to swing the cleaning components such as cleaning brushes and cleaning disks outwards relative to the robot body to perform the cleaning action. Moreover, when the cleaning is completed or when the cleaning components encounter an obstacle, the cleaning components need to swing back into the robot body.

[0003] In the existing cleaning robots, a driving source needs to be set for each of the rotational movement and the swing of the cleaning components, which results in a complex internal structure, a large volume, and a high assembly cost of the cleaning robot. Nowadays, there is already a mechanism that can simultaneously drive the rotation and swing of the cleaning components through a single driving source. For example, a swing cleaning mechanism, a design method, and a cleaning robot disclosed in the publication number CN118058661A can achieve the above effects, but it has strict proportional requirements for the speed ratio between the central rotating shaft and the cleaning components and the radius size of the cleaning components, and has high assembly accuracy requirements and great assembly difficulty.

[0009] Preferably, the number of the limiting assemblies is two. The two limiting assemblies are respectively disposed on the drive housing member and are respectively located at both ends of the swing path of the swing housing member.

[0010] Preferably, the transmission member includes a transmission shaft and a transmission gear disposed on the transmission shaft.

[0015] The beneficial effects of the present application are as follows: When it is not necessary to perform cleaning in the deployed state, the driving component drives forward, and at this time, the forward driving direction is the allowable movement direction. The driving component drives the cleaning component to rotate through the transmission of the rotating shaft component and the transmission member for cleaning operations. When it is necessary to perform cleaning in the deployed state, the driving component drives in the reverse direction. At this time, the reverse driving direction is the force-limiting locking direction. The roller member locks the first fitting and the second fitting, so that the first fitting cannot rotate relative to the second fitting. However, the driving force of the driving component still exists. Therefore, the first fitting will still rotate in the reverse direction and drive the second fitting to rotate in the reverse direction together, thereby rotating and deploying the swing housing member connected to the second fitting. When the swing housing member is deployed to be blocked and limited by the limiting component, the load of the driving component increases, and the driving torque of the driving component also increases accordingly, resulting in the thrust on the roller member gradually increasing to be greater than the locking force of the elastic locking groove. The elastic locking groove is squeezed and deformed, and the roller member moves into another roller receiving groove for self-rotation. The force-limiting locking direction and the allowable movement direction are switched. At this time, the reverse driving direction is the allowable movement direction. The driving component drives the cleaning component to rotate through the transmission of the rotating shaft component and the transmission member for cleaning operations. In this way, the present application can achieve the setting of only one driving source, driving the cleaning component to rotate for cleaning operations by one driving source, and at the same time, by changing the driving direction of the driving component, it can also achieve swinging the swing housing and the cleaning component to the deployed position for cleaning operations, simplifying the structure, reducing energy consumption, and saving manufacturing costs and manufacturing difficulties.

[0031] To further understand the application content, features and effects of the present application, the following embodiments are exemplified and described in detail with reference to the accompanying drawings as follows.

[0032] Embodiment 1:

[0033] Referring to Figures 1 - 3 , Figure 1 which is a cross-sectional view of the swing drive device in Embodiment 1, Figure 2 which is a schematic structural diagram of the swing drive device in Embodiment 1, Figure 3 which is a schematic structural diagram of the swing drive device after removing the transmission gear in Embodiment 1. The swing drive device in this embodiment includes a drive assembly 1, a rotating shaft assembly 2, a swing assembly 3, a damping commutation assembly 4 and a limit assembly 5. The rotating shaft assembly 2 is in transmission connection with the drive assembly 1. The swing assembly 3 includes a swing housing member 31 and a transmission member 32 rotatably arranged in the swing housing member 31. The swing housing member 31 is rotatably connected to the rotating shaft assembly 2, and the transmission member 32 is in transmission connection with the rotating shaft assembly 2. The damping commutation assembly 4 includes a first fitting 41, a second fitting 42 and a roller member 43. The first fitting 41 is sleeved outside the rotating shaft assembly 2. The second fitting 42 is rotatably sleeved outside the first fitting 41, and the second fitting 42 is connected to the swing housing member 31. The second fitting 42 is provided with an elastic locking groove 411. The notch of the elastic locking groove 411 faces the first fitting 41. The roller member 43 is accommodated in one end of the elastic locking groove 411. The distance between the middle of the bottom of the elastic locking groove 411 and the first fitting 41 is less than the outer diameter of the roller member 43. The limit assembly 5 is located on the swing path of the swing housing member 31.

[0034] Referring to Figures 4 - 6 together, Figure 4 which is a schematic principle diagram of the damping commutation assembly in Embodiment 1, Figure 5 which is a schematic structural diagram of the swing drive device in the initial position cleaning state in Embodiment 1, Figure 6Schematic structural diagram of the swing drive device in the placed position and clean state in Embodiment 1. Specifically in application, the swing drive device in this embodiment is applied to cleaning devices such as floor sweeping robots, and a cleaning component is connected to the transmission member 32. The cleaning component can be various forms of cleaning parts such as a cleaning brush or a cleaning disc. The drive component 1 has two drive forms: forward drive and reverse drive. The swing housing member 31 is rotatably connected to the rotating shaft assembly 2, that is, the swing housing member 31 can swing relative to the rotating shaft assembly 2, so that the swing housing member 31 has two position states: initial and placed. Among them, in the initial position state, the swing housing member 31 and the cleaning component are located inside the cleaning device or most of the area is located inside the cleaning device. At this time, the swing housing member 31 does not perform a placement. The drive component 1 drives the rotating shaft assembly 2 to rotate forward, and the forward rotation of the rotating shaft assembly 2 drives the first fitting 41 to rotate forward. The forward rotation of the first fitting 41 drives the roller member 43 to rotate within one end of the elastic locking groove 411, so that the first fitting 41 and the second fitting 42 rotate relative to each other. Since the second fitting 42 is connected to the swing housing member 31, that is, the swing housing member 31 does not swing and remains in the initial position, and the forward rotation of the rotating shaft assembly 2 will drive the transmission member 32 to rotate forward, and the forward rotation of the transmission member 32 will drive the cleaning component to rotate synchronously to clean the ground. In short, when no placement cleaning is required, the drive component 1 drives forward, the swing housing member 31 is in the initial position, and the cleaning component cleans in the initial position.

[0035] When it is necessary to perform cleaning in the extended position, the drive assembly 1 drives the rotating shaft assembly 2 to rotate in the reverse direction. The reverse rotation of the rotating shaft assembly 2 drives the first fitting 41 to rotate in the reverse direction. The reverse rotation of the first fitting 41 causes the roller member 43 to have a tendency to move from one end of the elastic locking groove 411 to the other end of the elastic locking groove 411. However, since the distance between the middle of the bottom of the elastic locking groove 411 and the first fitting 41 is less than the outer diameter of the roller member 43, at this time, the roller member 43 is blocked and cannot move into the other end of the elastic locking groove 411. That is, the roller member 43 dampedly locks the reverse rotation of the first fitting 41. However, the reverse driving force of the drive assembly 1 still exists. The reverse rotation of the rotating shaft assembly 2 will drive the first fitting 41, the second fitting 42 and the swing housing member 31 to rotate in the reverse direction, that is, to realize the rotation and extension of the swing housing member 31. When the swing housing member 31 is extended to a certain angle, it will be blocked and limited by the limiting assembly 5, so that the swing housing member 31 cannot continue to extend outwards. Also, because the elastic locking groove 411 has elasticity, when the drive assembly 1 continuously drives in the reverse direction, the roller member 43 squeezes the middle position of the bottom of the elastic locking groove 411 and causes it to undergo elastic deformation. The roller member 43 moves from one end of the elastic locking groove 411 to the other end of the elastic locking groove 411. At this time, the drive assembly 1 drives the rotating shaft assembly 2 to rotate in the reverse direction. The reverse rotation of the rotating shaft assembly 2 drives the first fitting 41 to rotate in the reverse direction. The reverse rotation of the first fitting 41 drives the roller member 43 to rotate self in the other end of the elastic locking groove 411, so that the first fitting 41 and the second fitting 42 rotate relatively. The reverse rotation of the rotating shaft assembly 2 will drive the transmission member 32 to rotate in the reverse direction, and the reverse rotation of the transmission member 32 will drive the cleaning assembly to rotate synchronously to realize cleaning the ground. In short, when it is necessary to perform cleaning in the extended position, the drive assembly 1 drives in the reverse direction, the swing housing member 31 swings to the extended position, and the cleaning assembly performs cleaning at the extended position. In this way, this embodiment can realize that only one drive source is set, and one drive source drives the cleaning assembly to rotate for cleaning operations. At the same time, by changing the driving direction of the drive assembly 1, the swing housing 31 and the cleaning assembly can be swung to the extended position for cleaning operations, which simplifies the structure, reduces energy consumption, and saves manufacturing costs and manufacturing difficulties.

[0036] Refer back to Figure 4, specifically, the elastic locking groove 411 can be divided into two roller receiving grooves with the middle part as the boundary. The distance between the middle part of the bottom of the elastic locking groove 411 and the first fitting 41 is less than the outer diameter of the roller member 43, and the depth of the roller receiving groove is greater than the outer diameter of the roller member 43. One end of the elastic locking groove 411 in this embodiment is one of the roller receiving grooves, and the other end of the elastic locking groove 411 is the other roller receiving groove. The roller member 43 can rotate self - in the roller receiving groove. It can be understood that the damping commutation assembly 4 in this embodiment is equivalent to a locking mechanism with a variable locking direction, having a permitted movement direction and a force - limiting locking direction. The permitted movement direction refers to the direction from the empty roller receiving groove to the roller receiving groove with the roller member 43, and the force - limiting locking direction refers to the direction from the roller receiving groove with the roller member 43 to the empty roller receiving groove. That is to say, when the first fitting 41 rotates relative to the second fitting 42 along the permitted movement direction, at this time, the first fitting 41 makes the roller member 43 rotate self - in the roller receiving groove, and this rotation direction is permitted, and the first fitting 41 can continuously rotate relative to the second fitting 42 along the permitted movement direction. When the first fitting 41 rotates relative to the second fitting 42 along the force - limiting locking direction, the first fitting 41 makes the roller member 43 tend to move to another roller receiving groove. However, due to the distance between the middle part of the bottom of the elastic locking groove 411 and the first fitting 41 being less than the outer diameter of the roller member 43, the roller member 43 is clamped between the middle part of the bottom of the elastic locking groove 411 and the first fitting 41, and the roller member 43 cannot rotate self - at this time, and the relative rotation between the first fitting 41 and the second fitting 42 is locked. Further, due to the elasticity of the elastic locking groove 411, when the thrust of the first fitting 41 on the roller member 43 is greater than the locking force, the roller member 43 will squeeze the bottom of the elastic locking groove 411, the elastic locking groove 411 deforms, the roller member 43 squeezes the bottom of the elastic locking groove 411 and moves from one roller receiving groove to another roller receiving groove. After moving to another roller receiving groove, the permitted movement direction and the force - limiting locking direction are reversed, and the original force - limiting locking direction is switched to the permitted movement direction. At this time, the roller member 43 can rotate self - in the other roller receiving groove, and the relative rotation between the first fitting 41 and the second fitting 42 is permitted. In short, the damping commutation assembly in this embodiment can achieve one - way locking, and when the rotational force is greater than the locking force, the force - limiting locking direction and the permitted movement direction will be switched.

[0037] In other words, when no cleaning in the deployed state is required, the drive assembly 1 drives forward, and at this time the forward drive direction is the allowable movement direction. The drive assembly 1 drives the cleaning assembly to rotate for cleaning operations through the transmission of the rotating shaft assembly 2 and the transmission member 32. When cleaning in the deployed state is required, the drive assembly 1 drives in the reverse direction. At this time, the reverse drive direction is the force-limiting lock direction. The roller member 43 locks the first fitting member 41 and the second fitting member 42, so that the first fitting member 41 cannot rotate relative to the second fitting member 42. However, the driving force of the drive assembly 1 still exists. Therefore, the first fitting member 41 will still rotate in the reverse direction and drive the second fitting member 42 to rotate in the reverse direction together, thereby rotating and deploying the swing housing member 31 connected to the second fitting member 42. When the swing housing member 31 is deployed and blocked and limited by the limiting assembly 5, the load of the drive assembly 1 increases, and the driving torque of the drive assembly 1 also increases accordingly, resulting in the thrust on the roller member 43 gradually increasing to be greater than the locking force of the elastic locking groove 411. The elastic locking groove 411 is squeezed and deformed, and the roller member 43 moves into another roller receiving groove for self-rotation. The force-limiting lock direction and the allowable movement direction are switched. At this time, the reverse drive direction is the allowable movement direction. The drive assembly 1 drives the cleaning assembly to rotate for cleaning operations through the transmission of the rotating shaft assembly 2 and the transmission member 32. Specifically, the roller member 43 is a component such as a roller or a rolling pin. The first fitting member 41 is cylindrical and sleeved outside the rotating shaft assembly 2. The second fitting member 42 is annular and sleeved outside the first fitting member 41, and the second fitting member 42 is integrally formed on the swing housing member 31. The second fitting member 42 is made of an elastic material. In this embodiment, the elastic locking groove 411 is formed on the second fitting member 42. In other embodiments, the elastic locking groove 411 can also be formed on the surface of the first fitting member 41.

[0038] Refer back to Figure 2 , preferably, the rotating shaft assembly 2 includes a swing middle shaft member 21 and two middle shaft rotating wheel members 22 respectively arranged at both ends of the swing middle shaft member 21. The swing housing member 31 is rotatably arranged on the swing middle shaft member 21. One of the middle shaft rotating wheel members 22 is located inside the swing housing member 31 and is in transmission connection with the transmission member 32, and the other middle shaft rotating wheel member 22 is in transmission connection with the drive assembly 1. The first fitting member 41 is sleeved outside the swing middle shaft member 21. In specific applications, the middle shaft rotating wheel member 22 is a swing gear, and the swing middle shaft member 21 is a swing middle shaft. The two swing gears are respectively sleeved at both ends of the swing middle shaft. One of the swing gears is in transmission connection with the transmission member 32 for transmitting power to the transmission member 32 and then to the cleaning assembly for cleaning operations. The other swing gear is in transmission connection with the drive assembly 1 for receiving the power of the drive assembly 1. Moreover, one end of the swing middle shaft rotatably penetrates through one end of the swing housing member 31. That is to say, the other end of the swing housing member 31 can swing with the swing middle shaft as the rotation axis, and the transmission member 32 and the cleaning assembly are close to the other end of the swing housing member 31. That is, as the swing housing member 31 swings, the cleaning assembly can be deployed for cleaning operations.

[0039] Referring to Figure 7 , Figure 7 which is a schematic structural diagram of the driving component in Embodiment 1. Preferably, the driving component 1 includes a driving housing part 11 and a driving part 12 arranged inside the driving housing part 11. The driving housing part 11 is rotatably arranged on the swinging central axis part 21. Another central axis rotating wheel part 22 is located inside the driving housing part 11 and is in transmission connection with the driving part 12. The swinging housing part 31 swings relative to the driving housing part 11 with the swinging central axis part 21 as the axis. The limiting component 5 is arranged on the driving housing part 11 and is located on the swinging path of the swinging housing part 31. In specific applications, the driving housing part 11 is fixedly connected to the housing of the sweeping robot. The two ends of the swinging central axis are respectively rotatably inserted through the driving housing part 11 and the swinging housing part 31. The driving housing part 11, the swinging housing part 31 and the swinging central axis form a rotating compound hinge at the axis of the swinging central axis. Any two of the driving housing part 11, the swinging housing part 31 and the swinging central axis can rotate relative to each other. That is to say, the swinging central axis is the swinging axis of the swinging housing part 31, and the swinging housing part 31 can rotate around the swinging central axis relative to the driving housing part 11 in a fixed-axis manner. The driving part 12 is arranged inside the driving housing part 11. In this embodiment, the driving part 12 is a driving motor. There is one-stage or multi-stage transmission structure between the driving part 12 and the swinging gear. The transmission structure includes a driving transmission shaft and a driving transmission gear. The driving transmission shaft is rotatably arranged inside the driving housing part 11. The driving transmission gear is sleeved outside the driving transmission shaft. The transmission structure is equivalent to a reduction gear set. In this embodiment, a gear is arranged on the output shaft of the driving motor. The number of the transmission structures is one. In this way, after one-stage reduction, the rotation direction of the driving motor is the same as that of the swinging central axis and the structure is simple. Of course, in other embodiments, the number of the transmission structures can be set according to actual needs to reduce the driving motor, which is not limited here. Specifically, the driving housing part 11 is a driving shell, and the swinging housing part 31 is a swinging shell.

[0040] Referring back to Figure 5 and Figure 6, preferably, the number of the limiting components 5 is two. The two limiting components 5 are respectively arranged on the driving housing part 11 and are respectively located at both ends of the swinging path of the swinging housing part 31. In specific application, the limiting component 5 is a limiting block. It can be understood that one of the limiting blocks is used to block when the swinging housing part 31 swings out, so that the swinging housing part 31 swings out to a preset angle, and the other limiting block is used to block when the swinging housing part 31 retracts, so that the swinging housing part 31 returns to the initial position. In this embodiment, the swinging angle of the swinging housing part 31 is 90°. Of course, in other embodiments, the position of the limiting component 5 can be adjusted according to actual needs. It can be understood that the process and principle of the swinging housing part 31 retracting are similar to those of the swinging housing part 31 swinging out and are the reverse process of the swinging out process. The damping commutation component 4 also undergoes a switching of the force-limiting locking direction and the allowable movement direction once. When the swinging housing part 31 swings out, at this time, the driving part 12 drives in the reverse direction, and the reverse driving direction is the allowable movement direction. The reverse driving of the driving part 12 can drive the cleaning component to continuously rotate. When it is necessary to retract the swinging housing part 31 to the original position, the driving part 12 rotates forward. At this time, the forward driving direction is the force-limiting locking direction, and the first fitting 41 and the second fitting 42 cannot rotate relative to each other, so that the swinging housing part 31 swings back to the original position. When the swinging housing part 31 swings back until it is blocked by the other limiting block, the force-limiting locking direction and the allowable movement direction are switched again. At this time, the forward driving of the driving part 12 can drive the cleaning component to continuously rotate. The forward direction and the reverse direction described in this embodiment are for the convenience of describing the relative relationship between the rotation directions of the driving part 12, the first fitting 41 and the second fitting 42, and do not limit the rotation directions of the driving part 12, the first fitting 41 and the second fitting 42.

[0041] Refer back to Figure 5 and Figure 6 , preferably, the transmission part 32 includes a transmission shaft 321 and a transmission gear 322 arranged on the transmission shaft 321. One end of the transmission shaft 321 is rotatably arranged on the swinging housing part 31, and the other end of the transmission shaft 321 passes through the swinging housing part 31 and extends outward. The transmission gear 322 meshes with the rotating shaft assembly 2, and the first fitting 41 is sleeved outside the rotating shaft assembly 2. In specific application, the transmission gear 322 meshes with the swinging gear. The swinging central shaft and the swinging gear rotate to drive the transmission gear 322 to rotate. The rotation of the transmission gear 322 drives the transmission shaft 321 to rotate. The other end of the transmission shaft 321 passes through the swinging housing part 31 and extends outward and is connected to the cleaning component, so as to drive the cleaning component to rotate for cleaning operations.

[0042] Refer back to Figure 5 and Figure 6, preferably, the number of the transmission shafts 321 and the transmission gears 322 are both multiple. A plurality of transmission shafts 321 are respectively rotatably arranged on the swing housing member 31, and a plurality of transmission gears 322 are respectively arranged corresponding to the plurality of transmission shafts 321. One transmission gear 322 meshes with the rotating shaft assembly 2, and the remaining transmission gears 322 are sequentially meshed one by one. The first fitting 41 is sleeved outside the rotating shaft assembly 2 or any one of the transmission shafts 321. In specific applications, in this embodiment, the number of the transmission shafts 321 and the transmission gears 322 are both two. One of the transmission gears 322 meshes with the swing-out gear, and the other transmission gear 322 meshes with one of the transmission gears 322. Moreover, the swing-out gear and the swing-out central shaft are close to one end of the swing housing member 1, and the other transmission gear 322 and the transmission shaft 321 connected thereto are close to the other end of the swing housing member 1. The transmission shaft 321 close to the other end of the swing housing member 1 is connected to the cleaning assembly. Of course, in other embodiments, the number of the transmission shafts 321 and the transmission gears 322 can also be set according to actual requirements, and no limitation is made here.

[0043] Refer back to Figure 4 , preferably, the number of the elastic locking grooves 411 and the roller members 43 are both multiple. A plurality of elastic locking grooves 411 are arranged at intervals in a ring shape on the second fitting 42, and a plurality of roller members 43 are respectively received in the plurality of elastic locking grooves 411. In specific applications, in this embodiment, the number of the elastic locking grooves 411 and the roller members 43 are both four. The four elastic locking grooves 411 are arranged at intervals in a ring shape on the second fitting 42, and a roller member 43 is correspondingly arranged in each elastic locking groove 411. Since the elastic force range of a single elastic locking groove 411 is limited, the locking force range that a single elastic locking groove 411 can provide is also limited. By providing a plurality of elastic locking grooves 411 on the second fitting 42, a roller member 43 can be correspondingly arranged in each elastic locking groove 411. In this way, the corresponding number of elastic locking grooves 411 can be set according to actual requirements to meet the situation where different locking forces need to be set in actual applications. Of course, in other embodiments, the number of the elastic locking grooves 411 and the roller members 43 can both be one, two or multiple, and the specific number is set according to the actual locking force requirements, and no limitation is made here. In addition, in this embodiment, the second fitting 42 is made of an elastic material, so that the bottom of the elastic locking groove 411 has a certain elasticity. Of course, in other embodiments, a second fitting 42 made of a non-elastic material can also be used, but an elastic member needs to be provided at the bottom of the elastic locking groove 411. The elastic member can be an elastic block, or a combination of a convex block and a spring, etc. It only needs to make the distance between the middle of the bottom of the elastic locking groove 411 and the first fitting 41 less than the outer diameter of the roller member 43, and after the force applied to the roller member 43 reaches a certain degree, the roller member 43 can squeeze the bottom of the elastic locking groove 411 and move to another roller receiving groove, which will not be elaborated here.

[0044] Refer back toFigures 4 - 6 , the working process and principle of the swing transmission device in this embodiment are as follows: The swing transmission device has two working states, namely the initial position cleaning state and the swung-out position cleaning state. In the initial position cleaning state, the swing housing member 31 is located at the initial position, and the driving member 12 drives forward. Through the transmission structure, the swing central axis and the swing gear are driven to rotate forward. The forward rotation of the swing central axis drives the first fitting member 41 to rotate forward. At this time, the forward driving direction is the allowable movement direction, and the forward rotation of the first fitting member 41 is allowed. The first fitting member 41 can rotate relative to the second fitting member 42, so that the swing central axis, the swing gear and the first fitting member 41 can continue to rotate forward. The forward rotation of the swing gear transmits power to the transmission gear 322 and the transmission shaft 321, and the rotation of the transmission shaft 321 drives the cleaning assembly to rotate for cleaning operations.

[0045] In the swung-out position cleaning state, the driving member 12 drives in the reverse direction. Through the transmission structure, the swing central axis and the swing gear are driven to rotate in the reverse direction. The reverse rotation of the swing central axis drives the first fitting member 41 to rotate in the reverse direction. At this time, the reverse rotation direction is the force-limiting and locking direction, and the reverse rotation of the first fitting member 41 is locked, so that the first fitting member 41 cannot rotate relative to the second fitting member 42. However, since the driving force of the driving member 12 still exists, the first fitting member 41 will still rotate in the reverse direction and drive the second fitting member 42 to rotate in the reverse direction together, thereby driving the other end of the swing housing member 31 to swing out with the swing central axis as the swing axis until the swing housing member 31 is blocked and limited by the limiting assembly 5. The load of the driving member 12 increases, and the driving torque of the driving member 12 also increases accordingly, resulting in the thrust on the roller member 43 gradually increasing to be greater than the locking force of the elastic locking groove 411. The elastic locking groove 411 is squeezed and deformed, and the roller member 43 moves into another roller receiving groove to rotate self, and the force-limiting locking direction and the allowable movement direction are switched. At this time, the reverse driving direction is the allowable movement direction, and the reverse rotation of the first fitting member 41 is allowed. The first fitting member 41 can rotate relative to the second fitting member 42, so that the swing central axis, the swing gear and the first fitting member 41 can continue to rotate in the reverse direction. The reverse rotation of the swing gear transmits power to the transmission gear 322 and the transmission shaft 321, and the rotation of the transmission shaft 321 drives the cleaning assembly to rotate for cleaning operations.

[0046] Embodiment Two:

[0047] Referring to Figure 8 , Figure 8 , which is a cross-sectional view of the swing transmission device in Embodiment Two. The difference between the swing transmission device in this embodiment and that in Embodiment One is that the first fitting member 41 in this embodiment is sleeved outside one of the transmission shafts 321 close to the swing central axis. By locking the rotation of the transmission shaft 321, the effect of swinging out the swing housing member 31 can also be achieved. The setting position of the damping commutation assembly 4 can be changed according to actual needs, and the structure is more flexible.

[0048] Embodiment Three:

[0049] Referring to Figure 9 , Figure 9 As shown in the sectional view of the swing drive device in Embodiment Three, the difference between the swing drive device in this embodiment and that in Embodiment One is that the first fitting 41 in this embodiment is sleeved outside one of the transmission shafts 321 far from the swing central axis. By locking the rotation of the transmission shaft 321, the effect of swinging out the swing housing part 31 can also be achieved. The installation position of the damping commutation component 4 can be changed according to actual needs, and the structure is more flexible.

[0050] Embodiment Four:

[0051] The cleaning device in this embodiment includes at least one swing drive device in Embodiment One and a housing. The drive component 1, the rotating shaft component 2, the swing component 3, the damping commutation component 4, and the limit component 5 are all arranged inside the housing. The cleaning component swings outwards and retracts relative to the housing, and the drive housing part 11 is fixedly connected to the housing.

[0052] In summary, when no swinging-out cleaning is required, the drive member 12 drives forward. At this time, the forward drive direction is the allowable movement direction. The drive member 12 drives the cleaning component to rotate through the transmission of the rotating shaft component 2 and the transmission member 32 for cleaning operations. When swinging-out cleaning is required, the drive member 12 drives in the reverse direction. At this time, the reverse drive direction is the force-limiting locking direction. The roller member 43 locks the first fitting 41 and the second fitting 42, making the first fitting 41 unable to rotate relative to the second fitting 42. However, the driving force of the drive member 12 still exists. Therefore, the first fitting 41 will still rotate in the reverse direction and drive the second fitting 42 to rotate in the reverse direction together, thereby rotating and swinging out the swing housing part 31 connected to the second fitting 42. When the swing housing part 31 swings out to be blocked and limited by the limit component 5, the load of the drive member 12 increases, and the driving torque of the drive member 12 also increases accordingly, causing the thrust on the roller member 43 to gradually increase to be greater than the locking force of the elastic locking groove 411. The elastic locking groove 411 is squeezed and deformed, and the roller member 43 moves into another roller receiving groove for self-rotation. The force-limiting locking direction and the allowable movement direction are switched. At this time, the reverse drive direction is the allowable movement direction. The drive member 12 drives the cleaning component to rotate through the transmission of the rotating shaft component 2 and the transmission member 32 for cleaning operations. In this way, this embodiment can achieve the setting of only one drive source, driving the cleaning component to rotate for cleaning operations by one drive source. At the same time, by changing the driving direction of the drive member 12, the swing housing 31 and the cleaning component can be swung to the swing-out position for cleaning operations, simplifying the structure, reducing energy consumption, and saving manufacturing costs and manufacturing difficulties.

[0053] The above are only the embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the scope of the claims of the present application.
