[0036] In one embodiment, the cleaning device 10 may be a cleaning robot with cleaning functions such as floor washing, floor mopping, and floor scrubbing. The cleaning device 10 can automatically move on the surface to be cleaned 10a to clean and remove dust from the surface to be cleaned 10a it passes through, and the cleaning device 10 of this embodiment can also scrub the surface to be cleaned 10a it passes through. The surface to be cleaned 10a may be the ground, or the surface to be cleaned of an object, etc.

[0037] The cleaning device 10 includes a device body 11. The device body 11 is the main part of the cleaning device 10, and is used to carry and protect the remaining parts of the cleaning device 10. Optionally, the device body 11 may be provided with a mechanism for driving the cleaning device 10 to move, such as a driving wheel, a crawler, etc. In addition, the device body 11 may also be provided with a wiping member such as a roller brush, and in addition, the device body 11 may also have a dust collection function.

[0038] The cleaning device 10 also includes a cleaning assembly 20, which is used to clean the surface to be cleaned 10a. Specifically, when the cleaning device 10 is applied to a cleaning robot, the cleaning assembly 20 can be designed to be rotatable, that is, the cleaning assembly 20 rotates around its own central axis to scrub the surface to be cleaned 10a. Optionally, the cleaning assembly 20 may include a rotatable cleaning member, for example, the cleaning assembly 20 includes a cleaning disk 21 and a cleaning member disposed on the cleaning disk 21, and the cleaning member may be a mopping member such as a rag.

[0039] The cleaning device 10 also includes a lifting assembly 30. The lifting assembly 30 is arranged on the device body 11, and the lifting assembly 30 is transmission-connected to the cleaning assembly 20. The lifting assembly 30 is used to drive the cleaning assembly 20 to rise and fall. The lifting direction of the cleaning assembly 20 is perpendicular to the surface to be cleaned 10a. When the cleaning assembly 20 is needed to clean the surface to be cleaned 10a, the lifting assembly 30 drives the cleaning assembly 20 to descend, so that the cleaning assembly 20 is close to the surface to be cleaned 10a to clean the surface to be cleaned 10a. When the cleaning assembly 20 is not needed to clean the surface to be cleaned 10a, the lifting assembly 30 drives the cleaning assembly 20 to rise, so that the cleaning assembly 20 is away from the surface to be cleaned 10a, which is conducive to improving the obstacle avoidance ability of the cleaning device 10.

[0040] Moreover, the lifting assembly 30 is also rotatably connected to the device body 11. When the cleaning device 10 needs to clean the corner area of ​​the cleaning surface 10a, the lifting assembly 30 drives the cleaning assembly 20 to swing outward from the device body 11 relative to the device body 11, such as Figure 2 When the cleaning device 10 does not need to clean the corner area of ​​the cleaning surface 10a, the lifting assembly 30 drives the cleaning assembly 20 relative to the device body 11 toward the inside of the device body 11, as shown in FIG. Figure 1 shown.

[0041] The cleaning device 10 also includes a driving assembly 40. The driving assembly 40 is in transmission connection with the cleaning assembly 20. The driving assembly 40 is the core driving component of the cleaning device 10. The driving assembly 40 is used to drive the cleaning assembly 20 to rotate to clean the surface to be cleaned 10a. The driving assembly 40 is also used to drive the cleaning assembly 20 to lift and lower through the lifting assembly 30. In addition, the driving assembly 40 is also used to drive the cleaning assembly 20 to swing through the lifting assembly 30. Further, the driving assembly 40 includes a driving member 41, and the driving member 41 has a driving shaft 42. The driving member 41 can drive the driving shaft 42 to rotate around its own central axis to output torque. The driving member 41 can be a power element such as a motor.

[0042] Please also read Figure 5 , Figure 5 It is a schematic diagram of the exploded structure of an embodiment of the lifting assembly of the present application.

[0043] In one embodiment, the lifting assembly 30 includes a box 30a, a lifting member 31, a transmission member 32, a guide member 33 and a selection transmission member 34. The box 30a is connected to the device body 11. The transmission member 32 is rotatably arranged on the box 30a, and the transmission member 32 is also respectively connected to the driving assembly 40 and the lifting member 31. The driving assembly 40 is connected to the cleaning assembly 20 through the lifting member 31, and the driving assembly 40 drives the lifting member 31 to rotate through the transmission member 32 to drive the cleaning assembly 20 to rotate. The lifting member 31 is also used to drive the cleaning assembly 20 to move closer to or away from the surface to be cleaned 10a relative to the transmission member 32, that is, to drive the cleaning assembly 20 to rise and fall. The lifting assembly 30 also includes a power output shaft 30b. The transmission member 32 is connected to the driving assembly 40 through the power output shaft 30b. The driving assembly 40 drives the power output shaft 30b to rotate around its own central axis, and the power output shaft 30b drives the transmission member 32 so that the transmission member 32 can rotate around the power output shaft 30b, thereby enabling the transmission member 32 to drive the lifting member 31 to rotate. The power output shaft 30b is specifically connected to the driving shaft 42 of the driving member 41 through a plurality of transmission gears, and the torque output by the driving member 41 acts on the power output shaft 30b so that the power output shaft 30b rotates around its own central axis. The guide member 33 is connected to the housing 30a by selecting the transmission member 34. The guide member 33 is also connected to the lifting member 31, and the guide member 33 is used to guide the lifting member 31 to approach or move away from the surface to be cleaned 10a relative to the transmission member 32, so that the lifting member 31 can drive the cleaning assembly 20 to approach or move away from the surface to be cleaned 10a relative to the transmission member 32.

[0044] The lifting design of the lifting assembly 30 according to the embodiment of the present application is described below.

[0045] Please also read Figure 6 and Figure 7 . In one embodiment, one of the lifting member 31 and the guide member 33 is provided with a spiral track 35, and the spiral track 35 extends spirally around the power output shaft 30b. The lifting assembly 30 also includes a guide movable member 37. The guide movable member 37 is disposed on the other of the lifting member 31 and the guide member 33, and the guide movable member 37 is movably disposed on the spiral track 35. In this embodiment, the lifting member 31 is guided to move closer to or away from the surface to be cleaned 10a relative to the transmission member 32 by moving the guide movable member 37 along the spiral track 35. Specifically, the transmission member 32 may be fixed in the axial direction of the power output shaft 30b, and the lifting member 31 moves along the axial direction of the power output shaft 30b.

[0046] Figure 6 and Figure 7Demonstrated exemplary guide member 33 is provided with spiral track 35, and lifting member 31 is provided with guide moving member 37.Guide moving member 37 can be roller etc., and guide moving member 37 is installed on lifting member 31 by fixed shaft.Spiral track 35 specifically can be chute structure etc.Guide moving member 37 protrudes from the outer sidewall of lifting member 31, makes guide moving member 37 can be embedded in spiral track 35, and guide moving member 37 can roll along spiral track 35, to guide lifting member 31 relative transmission member 32 along the axial movement of power output shaft 30b.Guide moving member 37 is rolling friction match with spiral track 35, helps to reduce the friction resistance between guide moving member 37 and spiral track 35.Certainly, in other embodiments of the application, guide moving member 37 also can adopt non-rollable design, and guide moving member 37 can slide along spiral track 35 instead, is not limited at this.

[0047] In one embodiment, the lifting assembly 30 also includes a limiting portion 36. The limiting portion 36 is disposed on the spiral track 35, and specifically, the limiting portion 36 is disposed at the end of the spiral track 35 close to the surface to be cleaned 10a. During the descent of the cleaning assembly 20, the guiding movable member 37 moves along the spiral track 35 and toward the surface to be cleaned 10a, driving the lifting assembly 31 to move toward the surface to be cleaned 10a. When the guiding movable member 37 moves to abut the limiting portion 36, the lifting assembly 31 drives the guide member 33 to rotate synchronously, specifically, the lifting member 31 supports the limiting portion 36 through the guiding movable member 37 to drive the guide member 33 to rotate synchronously, so that the guide member 33 can adapt to the cleaning assembly 20 to clean the surface to be cleaned 10a by rotation. At this time, the lifting member 31 descends to the first lifting limit position, and the cleaning assembly 20 can clean the surface to be cleaned 10a. Figure 3 shown.

[0048] The end of the spiral track 35 away from the surface 10a to be cleaned has a limit surface 353. When the guide moving member 37 moves to abut the limit surface 353, the limit surface 353 restricts the guide moving member 37 from continuing to move away from the surface 10a to be cleaned along the spiral track 35, thereby restricting the lifting member 31 from continuing to move away from the surface 10a to be cleaned. At this time, the lifting member 31 rises to the second lifting limit position, and the cleaning assembly 20 is away from the surface 10a to be cleaned. Figure 4 shown.

[0049] Furthermore, the limiting portion 36 is detachably connected to the spiral track 35, and the limiting portion 36 is configured to be connected to the spiral track 35 after the guide movable member 37 is installed in the spiral track 35. Considering that the limiting surface 353 and the guide member 33 are an integral structure, the limiting portion 36 and the guide member 33 are detachably connected in this embodiment, and the guide movable member 37 is installed in the spiral track 35 from the end of the spiral track 35 close to the surface 10a to be cleaned, and then the limiting portion 36 is connected to the guide member 33 to prevent the guide movable member 37 from coming out of the spiral track 35, so that the assembly can be convenient.

[0050] For example, the spiral track 35 includes a first spiral track 351 and a second spiral track 352. The first spiral track 351 and the second spiral track 352 are spaced apart along the circumference of the power output shaft 30b, and the spiral direction of the first spiral track 351 is the same as the spiral direction of the second spiral track 352. The first spiral track 351 and the second spiral track 352 are opened on the inner wall of the guide member 33. The limiting portion 36 includes a first limiting portion 361 and a second limiting portion 362, the first limiting portion 361 is arranged at the end of the first spiral track 351 close to the surface to be cleaned 10a, and the second limiting portion 362 is arranged at the end of the second spiral track 352 close to the surface to be cleaned 10a. In addition, the end of the first spiral track 351 away from the surface to be cleaned 10a and the end of the second spiral track 352 away from the surface to be cleaned 10a are respectively provided with corresponding limiting surfaces 353. Please refer to Figure 7 The guide moving member 37 comprises a first guide moving member 371 and a second guide moving member 372, the first guide moving member 371 and the second guide moving member 372 are spaced apart along the circumference of the power output shaft 30b, the first guide moving member 371 is movably arranged on the first spiral track 351, and the second guide moving member 372 is movably arranged on the second spiral track 352. When the first guide moving member 371 moves to abut the first limiting portion 361 and the second guide moving member 372 moves to abut the second limiting portion 362, the lifting member 31 drives the guide member 33 to rotate synchronously. The present embodiment is conducive to reliably and stably guiding the lifting member 31 to move relative to the transmission member 32 along the axial direction of the power output shaft 30b by arranging at least two groups of spiral tracks 35 and guide moving members 37.

[0051] Of course, in other embodiments of the present application, only one set of spiral tracks 35 and guide moving parts 37 may be provided, which can also realize the axial movement of the guiding lifting member 31 relative to the transmission member 32 along the power output shaft 30b, and can also simplify the structure of the lifting assembly 30.

[0052] It should be noted that, in this embodiment, when the driving member 41 outputs the second torque, the driving member 41 drives the transmission member 32 to rotate synchronously with the lifting member 31 through the power output shaft 30b, so as to drive the guide moving member 37 to move along the spiral track 35 and toward the surface to be cleaned 10a through the lifting member 31, and then guide the lifting member 31 to drive the cleaning component 20 to move toward the surface to be cleaned 10a. In this process, due to the transmission cooperation between the cleaning component 20 and the lifting member 31, the cleaning component 20 rotates adaptively. When the guided moving member 37 moves to the contact limit portion 36, the cleaning component 20 drops to the working position, and the power output shaft 30b continues to drive the cleaning component 20 to rotate to clean the surface to be cleaned 10a. At the same time, the power output shaft 30b also drives the guide member 33 to rotate synchronously. When the driving member 41 outputs a first torque opposite to the second torque, the power output shaft 30b also drives the transmission member 32 to rotate synchronously with the lifting member 31, so as to drive the guide moving member 37 to move along the spiral track 35 and in a direction away from the surface to be cleaned 10a through the lifting member 31, thereby guiding the lifting member 31 to drive the cleaning assembly 20 to move in a direction away from the surface to be cleaned 10a, until the guide moving member 37 moves to the contact limit surface 353. In this embodiment, the driving member 41 is rotated forward and reversely to control the cleaning assembly 20 to rise and fall.

[0053] The transmission member 34 is selected to be a one-way bearing. When the driving member 41 outputs the second torque, the transmission member 34 is selected to disconnect the transmission connection between the guide member 33 and the housing 30a, and the driving member 41 drives the cleaning assembly 20 to rotate through the lifting member 31 and also drives the guide member 33 to rotate synchronously, so that the guide member 33 can adapt to the cleaning assembly 20 to clean the surface to be cleaned 10a by rotating. When the driving member 41 outputs the first torque, the transmission member 34 is selected to connect the guide member 33 to the housing 30a, and the transmission member 34 is selected to limit the rotation of the guide member 33 relative to the housing 30a, so that the driving member 41 can drive the lifting assembly 30 to swing, which will be described in detail below. Specifically, the transmission member 34 is selected to have an outer ring and an inner ring, one of the outer ring and the inner ring is connected to the guide member 33, and the other is connected to the housing 30a, and the outer ring and the inner ring are used to selectively connect the guide member 33 to the housing 30a.

[0054] Please also read Figure 8 , Figure 8 It is a structural schematic diagram of an embodiment of a transmission member of the present application.

[0055] In one embodiment, one of the lifting member 31 and the transmission member 32 is provided with a stop track 38, and the stop track 38 extends in a direction perpendicular to the surface to be cleaned 10a. The lifting assembly 30 also includes a stop moving member 39. The stop moving member 39 is arranged on the other of the lifting member 31 and the transmission member 32, and the stop moving member 39 is movably arranged on the stop track 38 to allow the lifting member 31 to approach or move away from the surface to be cleaned 10a relative to the transmission member 32 and limit the relative rotation between the lifting member 31 and the transmission member 32. The stop moving member 39 can move along the stop track 38, so that the lifting member 31 and the transmission member 32 can move relative to each other in a direction perpendicular to the surface to be cleaned 10a, and the stop track 38 can cooperate with the stop moving member 39 to limit the relative rotation between the lifting member 31 and the transmission member 32.

[0056] Alternatively, the non-rotating moving member 39 can be a roller etc., and the non-rotating moving member 39 is installed on the lifting member 31 and / or the transmission member 32 by a fixed shaft. The non-rotating track 38 can specifically be a chute structure etc., and the non-rotating moving member 39 is embedded in the non-rotating track 38, and the non-rotating moving member 39 can roll along the non-rotating track 38, so that the lifting member 31 and the transmission member 32 can move relative to each other along the axial direction of the power output shaft 30b. Between the non-rotating moving member 39 and the non-rotating track 38, there is a rolling friction fit, which helps to reduce the friction resistance between the non-rotating moving member 39 and the non-rotating track 38. Of course, in other embodiments of the present application, the non-rotating moving member 39 can also adopt a non-rollable design, and the non-rotating moving member 39 can slide along the non-rotating track 38 instead, which is not limited at this.

[0057] For example, Figure 7 and Figure 8 The situation that the lifting member 31 and the transmission member 32 are both provided with the stop track 38 and the stop moving member 39 is shown exemplarily. Specifically, the stop track 38 comprises a first stop track 381 and a second stop track 382. The first stop track 381 is arranged at the transmission member 32, and the second stop track 382 is arranged at the lifting member 31, and the first stop track 381 and the second stop track 382 are distributed at intervals along the circumference of the power output shaft 30b. The stop moving member 39 comprises a first stop moving member 391 and a second stop moving member 392. The first stop moving member 391 is arranged at the transmission member 32, and the second stop moving member 392 is arranged at the lifting member 31, and the first stop moving member 391 and the second stop moving member 392 are distributed at intervals along the circumference of the power output shaft 30b. The first stop moving member 391 is movably arranged at the second stop track 382, ​​and the second stop moving member 392 is movably arranged at the first stop track 381.

[0058] Of course, in other embodiments of the present application, one of the lifting member 31 and the transmission member 32 may be provided with a spiral track 35, and the other may be provided with a guide moving member 37, so that the lifting member 31 and the transmission member 32 rotate relative to each other to guide the lifting member 31 to approach or move away from the surface to be cleaned 10a. Correspondingly, one of the lifting member 31 and the guide member 33 may be provided with a stop track 38, and the other may be provided with a stop moving member 39, so as to guide the lifting member 31 to approach or move away from the surface to be cleaned 10a relative to the guide member 33 and limit the relative rotation between the lifting member 31 and the guide member 33. In this way, when the lifting member 31 drives the cleaning component 20 to approach or move away from the surface to be cleaned 10a, the cleaning component 20 does not rotate.

[0059] In one embodiment, please refer to Fig. 9 The lifting member 31 includes a first transmission part 311 and a guide part 313. The guide part 313 is arranged around the outer periphery of the first transmission part 311, and the guide part 313 is connected to the first transmission part 311 through a first connecting part 314. The lifting member 31 generally presents a double-layer sleeve structure nested inside and outside, wherein the first transmission part 311 is the inner sleeve of the lifting member 31, the guide part 313 is the outer sleeve of the lifting member 31, and the same side ends of the first transmission part 311 and the guide part 313 are connected through the first connecting part 314. The first guide moving member 371 and the second guide moving member 372 are located on the outer side wall of the guide part 313, and the first guide moving member 371 and the second guide moving member 372 are arranged opposite to each other. The first transmission part 311 has a transmission cavity 312 inside, and a part of the cleaning component 20 is embedded in the transmission cavity 312 to be transmission-connected with the first transmission part 311. Please refer to Fig.10 The cleaning disc 21 of the cleaning assembly 20 has a transmission column 22 on the side facing away from the cleaning member. The transmission column 22 is a prism. The inner side wall of the transmission cavity 312 is a polyhedral structure corresponding to the transmission column 22, such as Fig. 9 As shown. The transmission column 22 is embedded in the transmission cavity 312, and the outer wall of the transmission column 22 and the inner wall of the transmission cavity 312 cooperate with each other to stop rotation, so that the lifting member 31 is connected to the cleaning component 20 in a transmission manner, that is, the lifting member 31 can drive the cleaning component 20 to rotate. The guide part 313 is also connected to the guide member 33. The inner wall of the guide part 313 and the outer wall of the first transmission part 311 are spaced apart from each other to form a accommodating cavity 315. The second anti-rotation moving member 392 is located on the inner wall of the guide part 313. The number of the second anti-rotation moving member 392 can be one or more, Figure 7The example shows that there are two second anti-rotation moving members 392, and the two second anti-rotation moving members 392 are evenly spaced along the circumference of the guide portion 313. The first guide moving member 371, the second guide moving member 372 and the second anti-rotation moving member 392 are located at the end of the guide portion 313 away from the first connecting portion 314. The second anti-rotation track 382 is located on the outer side wall of the first transmission portion 311. The number of the second anti-rotation track 382 can be one or more, Figure 7 The example shows that there are two second stop rails 382, ​​and the two second stop rails 382 are evenly spaced along the circumference of the first transmission part 311. The first guide moving member 371 and the second guide moving member 372 are respectively arranged opposite to a corresponding second stop rail 382. Each second stop moving member 392 and each second stop rail 382 are alternately distributed one by one along the circumference of the lifting member 31.

[0060] Please continue reading Figure 8 The transmission member 32 includes a second connecting portion 321 and a second transmission portion 322. The second connecting portion 321 is transmission-connected to the power output shaft 30b. The second connecting portion 321 can be locked to the power output shaft 30b by fasteners such as screws. The second transmission portion 322 is arranged around the outer periphery of the second connecting portion 321. The transmission member 32 generally presents a hollow sleeve structure. The second transmission portion 322 is embedded in the accommodating cavity 315, so that the structure of the lifting member 31 and the transmission member 32 is relatively compact, which is conducive to the miniaturization design of the lifting assembly 30. The second transmission portion 322 is transmission-connected to the first transmission portion 311 and / or the guide portion 313. The first anti-rotation moving member 391 is located on the inner side wall of the second transmission portion 322. The number of the first anti-rotation moving member 391 can be one or more, Figure 8 The example shows that there are two first anti-rotation moving members 391, and the two first anti-rotation moving members 391 are evenly spaced along the circumference of the second transmission part 322. The first anti-rotation moving member 391 is located at the end of the second transmission part 322 away from the second connecting part 321. The first anti-rotation track 381 is located on the outer side wall of the second transmission part 322. The number of the first anti-rotation track 381 can be one or more. Figure 8 The example shows that there are two first anti-rotation rails 381, and the two first anti-rotation rails 381 are evenly spaced along the circumference of the second transmission part 322. The first anti-rotation moving parts 391 and the first anti-rotation rails 381 are alternately distributed one by one along the circumference of the second transmission part 322. In this embodiment, a multi-stage sleeve structure is provided, and the structure of the lifting mechanism is simple, which can realize the miniaturization and lightness of the lifting mechanism, and is conducive to reducing the cost of the lifting mechanism.

[0061] The swing design of the lifting assembly 30 according to the embodiment of the present application is described below.

[0062] Please continue reading Figures 3 to 5 In one embodiment, the housing 30a is rotatably connected to the device body 11, and the housing 30a can drive the remaining parts of the lifting assembly 30 thereon to swing relative to the device body 11. Optionally, the cleaning device 10 further includes a rotating bearing 70, and the housing 30a is rotatably connected to the device body 11 via the rotating bearing 70. When the driving assembly 40 outputs a first torque, the transmission member 34 is selected to drive the guide member 33 to the housing 30a, and the guide member 33 guides the lifting member 31 away from the surface to be cleaned 10a, and the driving assembly 40 drives the lifting assembly 30 via the guide member 33 relative to the device body 11 along a first swinging direction (such as Figure 1 The cleaning device 10 further includes a first elastic member 50, which is connected to the device body 11 and the lifting assembly 30, respectively. The first elastic member 50 is used to drive the lifting assembly 30 to swing relative to the device body 11 in a second swing direction (such as Figure 1 The device swings as shown by the arrow P2 in the middle, the same below).

[0063] Specifically, when the driving member 41 outputs the first torque, the transmission member 34 is selected to connect the guide member 33 with the box body 30a, and the transmission member 34 is selected to limit the rotation of the guide member 33 relative to the box body 30a, that is, the guide member 33 remains stationary relative to the box body 30a, and the guide member 33 guides the lifting member 31 to move in a direction away from the surface to be cleaned 10a, until the guide moving member 37 moves to the contact limit surface 353, at which time the driving member 41 can no longer drive the lifting member 31 to rotate, and the transmission system of the driving component 40 and the lifting component 30 is locked, so that the driving member 41 can drive the lifting component 30 to swing relative to the device body 11 along the first swinging direction, so that the lifting component 30 drives the cleaning component 20 to swing relative to the device body 11 along the first swinging direction. The torque direction applied by the first elastic member 50 to the lifting component 30 is opposite to the first swinging direction, so that the first elastic member 50 can drive the lifting component 30 to swing relative to the device body 11 along the second swinging direction, that is, the lifting component 30 drives the cleaning component 20 to swing relative to the device body 11 along the second swinging direction.

[0064] In the above manner, the embodiment not only drives the cleaning assembly 20 to perform lifting work through the driving assembly 40, but also drives the cleaning assembly 20 to perform swinging work through the lifting assembly 30. Different from the prior art in which the lifting work and the swinging work of the rag are independently controlled by different driving systems, the embodiment can simplify the structure of the cleaning device 10, which is conducive to the miniaturization and lightweight design of the cleaning device 10, and is conducive to reducing the cost of the cleaning device 10. In addition, the embodiment drives the lifting assembly 30 to swing relative to the device body 11 in a second swinging direction opposite to the first swinging direction through the first elastic member 50, that is, the embodiment realizes the design of swinging in and out of the cleaning assembly 20 through the cooperation of the driving assembly 40 and the first elastic member 50.

[0065] Optionally, the device body 11 has a mounting seat 111, the mounting seat 111 has a mounting cavity 112 inside, the driving assembly 40 is installed in the mounting cavity 112, and specifically, the driving member 41 is accommodated in the mounting cavity 112. The first elastic member 50 can be an elastic element such as a spring. The first elastic member 50 is arranged around the outer periphery of the mounting seat 111, and one end of the first elastic member 50 is fixedly connected to the mounting seat 111, and the other end is fixedly connected to the box 30a of the lifting assembly 30.

[0066] In one embodiment, when the driving component 40 outputs a first torque, the lifting component 30 swings relative to the device body 11 toward the inside of the device body 11, that is, the first swinging direction points to the inside of the device body 11; when the driving component 40 outputs a second torque opposite to the first torque direction, the transmission member 34 is selected to disconnect the transmission connection between the guide member 33 and the box body 30a, and the driving component 40 drives the cleaning component 20 to rotate through the lifting member 31 and also drives the guide member 33 to rotate synchronously; the first elastic member 50 is used to drive the lifting component 30 to swing relative to the device body 11 toward the outside of the device body 11, that is, the second swinging direction points to the outside of the device body 11.

[0067] In the above manner, the driving assembly 40 of the present embodiment is used to drive the lifting assembly 30 to swing toward the inside of the device body 11 relative to the device body 11, and the first elastic member 50 drives the lifting assembly 30 to swing toward the outside of the device body 11 relative to the device body 11. In this way, after the first elastic member 50 drives the lifting assembly 30 to swing toward the outside of the device body 11 relative to the device body 11, the cleaning assembly 20 can clean the corner area of ​​the surface to be cleaned 10a. When the cleaning assembly 20 touches an obstacle, the obstacle causes the cleaning assembly 20 to swing toward the inside of the device body 11, so that the cleaning assembly 20 avoids the obstacle, and after the cleaning assembly 20 passes the obstacle, the first elastic member 50 drives the cleaning assembly 20 to swing toward the outside of the device body 11 again through the lifting assembly 30, so that the cleaning assembly 20 can continue to clean the corner area of ​​the surface to be cleaned 10a, thereby realizing the obstacle avoidance function of the cleaning assembly 20.

[0068] In one embodiment, the limit position of the lifting assembly 30 relative to the device body 11 in the first swing direction is the first swing limit position. Figure 1 The limit position of the lifting assembly 30 relative to the device body 11 in the second swing direction is the second swing limit position, as shown in FIG. Figure 2 As shown. The cleaning device 10 also includes a limit assembly 60, which is arranged on the device body 11 and / or the lifting assembly 30, and the limit assembly 60 is used to limit the lifting assembly 30 to the first swing limit position. In this way, after the driving assembly 40 drives the lifting assembly 30 to swing to the first swing limit position, the limit assembly 60 limits the lifting assembly 30 to the first swing limit position. Since the cleaning assembly 20 also needs to perform cleaning work when the lifting assembly 30 is in the first swing limit position, that is, when the lifting assembly 30 is in the first swing limit position, the driving assembly 40 needs to output a second torque so that the cleaning assembly 20 descends to clean the surface 10a to be cleaned. When the driving assembly 40 outputs the second torque, due to the elastic restoring force of the first elastic member 50, the lifting assembly 30 has a tendency to swing relative to the device body 11 along the second swing direction. At this time, the driving assembly 40 cannot keep the lifting assembly 30 at the first swing limit position, so the limit assembly 60 is required to limit the lifting assembly 30 to the first swing limit position.

[0069] Specifically, the limiting assembly 60 includes a limiting column 61 and a limiting hole 62. The limiting column 61 is telescopically disposed at one of the device body 11 and the lifting assembly 30, and the limiting hole 62 is disposed at the other of the device body 11 and the lifting assembly 30. The limiting column 61 is configured to be able to extend and be embedded in the limiting hole 62 to limit the lifting assembly 30 to a first swing limit position, and after the limiting column 61 is disengaged from the limiting hole 62, the lifting assembly 30 is allowed to swing relative to the device body 11 along a second swing direction.

[0070] Of course, in other embodiments of the present application, the limit assembly 60 is not limited to the design of the above-mentioned limit column 61 and the limit hole 62. For example, the lifting assembly 30 can also be limited to the first swing limit position by a snap-fit ​​structure, a magnetic structure, etc. between the device body 11 and the lifting assembly 30, which is not limited here.

[0071] In one embodiment, the limiting column 61 is telescopically disposed on the device body 11, and the limiting hole 62 is disposed on the lifting assembly 30. Specifically, the limiting hole 62 is located in the box 30a of the lifting assembly 30. The power output shaft 30b has a movable cavity 30c extending along its axial direction. The movable cavity 30c is arranged opposite to the limiting hole 62. The limiting assembly 60 also includes a push rod 63, which is movably embedded in the movable cavity 30c. The push rod 63 can push the limiting column 61 out of the limiting hole 62 as the lifting member 31 moves away from the surface to be cleaned 10a, so that the limiting column 61 is disengaged from the limiting hole 62; the push rod 63 can also move the lifting member 31 close to the surface to be cleaned 10a to allow the limiting column 61 to be embedded in the limiting hole 62, so that the limiting column 61 cooperates with the limiting hole 62 to limit the lifting assembly 30 to the first swing limit position.

[0072] Of course, in other embodiments of the present application, the limiting column 61 may be telescopically disposed on the lifting assembly 30 , and the limiting hole 62 may be disposed on the device body 11 , which is not limited here.

[0073] Furthermore, the limiting assembly 60 further includes a second elastic member 64. The second elastic member 64 is connected to the power output shaft 30b and the push rod 63, respectively, and the second elastic member 64 is used to drive the push rod 63 and the lifting member 31 to approach the surface to be cleaned 10a. The second elastic member 64 can be an elastic element such as a spring, and the second elastic member 64 is sleeved on the outer periphery of the push rod 63. The power output shaft 30b and the push rod 63 can both be provided with a step surface, and the second elastic member 64 is sandwiched between the step surfaces on the power output shaft 30b and the push rod 63.

[0074] After the driving assembly 40 drives the lifting assembly 30 to swing to the first swing limit position, the driving assembly 40 outputs the second torque, and the second elastic member 64 applies a force to the lifting member 31 through the push rod 63, so that the lifting member 31 approaches the surface to be cleaned 10a, that is, the lifting member 31 drives the cleaning assembly 20 to descend, and at this time, the second elastic member 64 synchronously drives the push rod 63 to approach the surface to be cleaned 10a, so that the push rod 63 retracts into the limiting hole 62 and allows the limiting column 61 to be embedded in the limiting hole 62. It should be noted that, when the driving assembly 40 outputs the second torque, the transmission member 34 is selected to disconnect the transmission connection between the guide member 33 and the box body 30a, and the force of the second elastic member 64 on the lifting member 31 can ensure that the lifting member 31 moves toward the surface to be cleaned 10a relative to the guide member 33, reducing the risk that the lifting member 31 cannot move toward the surface to be cleaned 10a due to the synchronous rotation of the lifting member 31 and the guide member 33. At this time, the guide moving member 37 moves along the spiral track 35 synchronously with the movement of the lifting member 31.

[0075] Further, the moving cavity 30c penetrates the power output shaft 30b along the axial direction of the power output shaft 30b. The transmission member 32 is provided with an avoidance hole 323, and the avoidance hole 323 is arranged opposite to the moving cavity 30c. The push rod 63 is penetrated through the avoidance hole 323 to cooperate with the lifting member 31 in transmission, that is, the push rod 63 passes through the avoidance hole 323 and abuts against the lifting member 31. The avoidance hole 323 is specifically a second connection portion 321 opened in the transmission member 32. When the driving component 40 outputs the first torque, the transmission member 34 is selected to connect the guide member 33 with the box body 30a in transmission to limit the guide member 33 from rotating relative to the box body 30a. The driving component 40 drives the transmission member 32 to rotate synchronously with the lifting member 31, so that the lifting member 31 moves in a direction away from the surface to be cleaned 10a under the guidance of the guide member 33, and the lifting member 31 drives the push rod 63 to synchronously move away from the surface to be cleaned 10a, so that the push rod 63 pushes the limit column 61 out of the limit hole 62. When the driving assembly 40 outputs the second torque, the second elastic member 64 pushes the lifting member 31 toward the surface to be cleaned 10 a through the push rod 63 , and the push rod 63 retracts into the limiting hole 62 to allow the limiting column 61 to be inserted into the limiting hole 62 .

[0076] Furthermore, the limiting assembly 60 also includes a third elastic member 65. The limiting column 61 is arranged on one of the device body 11 and the lifting assembly 30 through the third elastic member 65, and the third elastic member 65 is used to drive the limiting column 61 to be embedded in the limiting hole 62. For the above-mentioned example in which the limiting column 61 is telescopically arranged on the device body 11, the limiting column 61 of this embodiment is arranged on the device body 11 through the third elastic member 65. The third elastic member 65 can be an elastic element such as a spring, and the third elastic member 65 is sandwiched between the limiting column 61 and the device body 11. A cavity matching the limiting column 61 can be provided on the device body 11, and the limiting column 61 is embedded in the cavity, and the cavity can limit the limiting column 61 from escaping therefrom.

[0077] In one embodiment, the central axis of the rotating bearing 70 coincides with the central axis of the driving shaft 42; or, the driving assembly 40 also includes a first transmission gear 43 that is transmission-connected to the driving shaft 42, and the lifting assembly 30 also includes a second transmission gear 80 that meshes with the first transmission gear 43, and the central axis of the rotating bearing 70 coincides with the central axis of the second transmission gear 80. Figure 3 and Figure 4 The example shows that the central axis of the rotating bearing 70 coincides with the central axis of the driving shaft 42 , and the rotating bearing 70 is disposed around the outer circumference of the driving shaft 42 .

[0078] The technical solution provided in the embodiments of the present application is described below in conjunction with specific application scenarios.

[0079] Application scenario 1:

[0080] The cleaning device 10 is a cleaning robot. The cleaning assembly 20 of the cleaning device 10 includes a rotatable cleaning member, which is a rag. The cleaning assembly 20 rotates around its own central axis to scrub and clean the floor.

[0081] like Figure 1 As shown, when the lifting component 30 of the cleaning device 10 is in the first swing limit position, the cleaning component 20 is in the swing-in state. The limiting column 61 on the device body 11 is embedded in the limiting hole 62, and the limiting column 61 cooperates with the limiting hole 62 to limit the lifting component 30 to the first swing limit position. The driving component 40 outputs a second torque, and the transmission member 34 is selected to disconnect the transmission connection between the guide member 33 and the box body 30a. The second elastic member 64 applies a force to the lifting component 31 through the push rod 63, so that the lifting component 31 approaches the surface to be cleaned 10a, that is, the lifting component 31 drives the cleaning component 20 to descend, so that the cleaning component 20 approaches the surface to be cleaned 10a to clean the surface to be cleaned 10a. Figure 3 shown.

[0082] like Figure 4 As shown, when the cleaning device 10 needs to clean the corner area of ​​the surface to be cleaned 10a, the driving member 41 outputs the first torque, and the transmission member 34 is selected to transmit the connection between the guide member 33 and the box body 30a to limit the rotation of the guide member 33 relative to the box body 30a. At the same time, the driving member 41 drives the transmission member 32 and the lifting member 31 to rotate synchronously, so that the lifting member 31 moves in a direction away from the surface to be cleaned 10a under the guidance of the guide member 33. The lifting member 31 drives the cleaning component 20 away from the surface to be cleaned 10a, that is, the lifting member 31 drives the cleaning component 20 to rise, and the lifting member 31 also drives the push rod 63 away from the surface to be cleaned 10a, so that the push rod 63 pushes the limit column 61 out of the limit hole 62 to allow the lifting component 30 to swing relative to the device body 11 toward the outside of the device body 11. When the lifting member 31 rises to the second lifting limit position, the push rod 63 pushes the limit column 61 out of the limit hole 62, and the driving member 41 can no longer drive the lifting member 31 to rotate, and the transmission system of the driving assembly 40 and the lifting assembly 30 is locked. After that, the first elastic member 50 drives the lifting assembly 30 to swing out relative to the device body 11 toward the outside of the device body 11 until the lifting assembly 30 swings relative to the device body 11 to the second swing limit position, so that the cleaning assembly 20 swings out to clean the corner area of ​​the surface 10a to be cleaned, such as Figure 2As shown. Since the driving member 41 has a locking function after power failure, the driving member 41 outputs a torque in the same direction as the second torque during the process of the lifting assembly 30 swinging outward from the device body 11 relative to the device body 11, so as to prevent the lifting assembly 30 from getting stuck and being unable to swing. When the lifting assembly 30 swings to the second swing limit position relative to the device body 11, the driving member 40 outputs the second torque, and the transmission member 34 is selected to disconnect the transmission connection between the guide member 33 and the box body 30a. The second elastic member 64 applies a force to the lifting member 31 through the push rod 63, so that the lifting member 31 approaches the surface to be cleaned 10a, that is, the lifting member 31 drives the cleaning assembly 20 to descend, so that the cleaning assembly 20 approaches the surface to be cleaned 10a to clean the surface to be cleaned 10a.

[0083] When the cleaning device 10 does not need to clean the corner areas of the surface to be cleaned 10a, the driving member 41 outputs the first torque, and the transmission member 34 is selected to connect the guide member 33 with the box body 30a to limit the guide member 33 from rotating relative to the box body 30a. At the same time, the driving member 41 drives the transmission member 32 to rotate synchronously with the lifting member 31, so that the lifting member 31 moves in a direction away from the surface to be cleaned 10a under the guidance of the guide member 33. The lifting member 31 drives the cleaning component 20 away from the surface to be cleaned 10a, that is, the lifting member 31 drives the cleaning component 20 to rise. The lifting component 31 to be lifted rises to the second lifting limit position. At this time, the driving member 41 can no longer drive the lifting member 31 to rotate, and the transmission system of the driving component 40 and the lifting component 30 is locked. The driving member 41 can overcome the elastic restoring force of the first elastic member 50 and drive the lifting component 30 to swing relative to the device body 11 toward the inside of the device body 11, so that the lifting component 30 drives the cleaning component 20 to swing relative to the device body 11 toward the inside of the device body 11, such as Figure 1 The lifting component 30 swings relative to the device body 11 to the first swing limit position, and the driving component 40 is controlled to output the second torque to drive the cleaning component 20 to descend, so that the cleaning component 20 approaches the surface to be cleaned 10a to clean the surface to be cleaned 10a, and the limiting column 61 is embedded in the limiting hole 62 to limit the lifting component 30 to the first swing limit position, as shown in FIG. Figure 3 shown.

[0084] The cleaning device provided by the present application is introduced in detail above. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea; at the same time, for general technicians in this field, according to the idea of ​​the present application, there will be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
