In all examples shown and discussed here, any specific values ​​should be interpreted as being merely exemplary, not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0057] See also Figures 1 to 14As shown, according to an embodiment of the present application, a cleaning device is provided, which includes a main body 10, a cleaning assembly 20, a connecting assembly 30, a first driving assembly 40 and a second driving assembly 50.

[0058] The cleaning assembly 20 is disposed at the bottom of the main body 10. The connecting assembly 30 is disposed on the cleaning assembly 20, and the cleaning assembly 20 can reciprocate relative to the connecting assembly 30 in a first direction. A first drive assembly 40 is disposed between the connecting assembly 30 and the main body 10, and the first drive assembly 40 drives the connecting assembly 30 to raise and lower the cleaning assembly 20 along the height direction of the main body 10. A second drive assembly 50 is disposed between the main body 10 and the cleaning assembly 20, and drives the cleaning assembly 20 to expand outward in the first direction to protrude beyond the outer edge of the main body 10, or to retract the cleaning assembly 20 in the first direction to the inner side of the main body 10.

[0059] Specifically, the cleaning device includes at least a sweeping robot, a floor scrubber, and a multifunctional cleaning station. In existing cleaning devices, due to the single structure, the cleaning device is difficult to use in some scenarios. For example, in most cleaning devices, when the cleaning component 20 is expanded to clean and encounters an obstacle, the cleaning component 20 needs to be retracted to the inner side of the main body 10 before the cleaning component 20 can be lifted. When the cleaning component 20 is not retracted in time, the cleaning component 20 is prone to scratching with the obstacle, eventually causing damage to the cleaning component 20. In addition, in some cleaning devices, after the cleaning component 20 is lifted, it is impossible to expand the cleaning component 20 to a position protruding from the outer edge of the main body 10, which means that the cleaning device cannot clean walls and other wall surfaces.

[0060] In this embodiment, a connecting assembly 30 is provided on the cleaning assembly 20, and the cleaning assembly 20 can slide relative to the connecting assembly 30 in a first direction. At the same time, the first driving assembly 40 only needs to apply a driving force to the connecting assembly 30 to control the cleaning assembly 20 to rise or fall in the height direction of the main body 10. Specifically, when the second driving assembly 50 drives the cleaning assembly 20 to expand outward in the first direction, the connecting assembly 30 will not be affected by the second driving assembly 50 and will not move. At the same time, the connecting assembly 30 is connected to the cleaning assembly 20. At this time, the connecting assembly 30 can be driven by the action of the first driving assembly 40, thereby causing the cleaning assembly 20 to rise or fall. In other words, through the provision of the connecting assembly 30, regardless of whether the cleaning assembly 20 reciprocates in the first direction, the first driving assembly 40 can drive the connecting assembly 30 to lift or lower the cleaning assembly 20, thereby facilitating the cleaning device to adapt to applications in more scenarios.

[0061] In addition, in some embodiments, the second drive assembly 50 can be raised and lowered as the cleaning assembly 20 is raised and lowered, so that the cleaning assembly 20 is expanded outwards by the second drive assembly 50 during the raising and lowering. At the same time, in this embodiment, the first drive assembly 40 and the second drive assembly 50 operate independently of each other, that is, when the first drive assembly 40 controls the raising and lowering of the cleaning assembly 20, it will not affect the second drive assembly 50 controlling the expansion of the cleaning assembly 20.

[0062] Furthermore, the first drive assembly 40 includes a first drive portion 42 and a pulling portion 41. The first drive portion 42 is disposed on the main body 10, and the pulling portion 41 is connected between the connecting assembly 30 and the first drive portion 42. The first drive portion 42 drives the pulling portion 41 to move the cleaning assembly 20 upward or downward along the height direction of the main body 10.

[0063] Specifically, in this embodiment, after the first driving unit 42 is activated, it can apply an upward force in the height direction to the pulling unit 41, thereby causing the pulling unit 41 to rise. The pulling unit 41 then transmits the external force to the connecting assembly 30, causing the connecting assembly 30 to drive the cleaning assembly 20 upward. Furthermore, after the first driving unit 42 stops, the first driving unit 42 removes the external force applied to the pulling unit 41. At this point, the force of gravity acting on the cleaning assembly 20 is greater than the pulling force applied by the pulling unit 41 on the cleaning assembly 20, causing the cleaning assembly 20 to descend under the action of gravity. Alternatively, in some embodiments, the first driving unit 42 can drive the pulling unit 41 to rise or fall in the height direction, causing the pulling unit 41 to drive the cleaning assembly 20 to rise or fall.

[0064] As attached Figure 11 As shown, the first driving unit 42 includes a first motor 421, and the pulling unit 41 includes a pull rope 411 and a reel 412. The pull rope 411 is wound around the reel 412, one end of the pull rope 411 is connected to the connecting assembly 30, and the reel 412 is connected to the rotating shaft of the first motor 421. The first motor 421 has a first working state in which it drives the reel 412 to reel in the pull rope 411 to raise the cleaning assembly 20, and a second working state in which it drives the reel 412 to unreel the pull rope 411 to lower the cleaning assembly 20.

[0065] Specifically, when the first motor 421 is in the first working state, the first motor 421 rotates forward, thereby driving the reel 412 to rotate forward, so that the pull rope 411 is reeled on the reel 412. After the pull rope 411 is reeled, it applies an external force in the height direction to the connecting assembly 30, so that the connecting assembly 30 drives the cleaning assembly 20 to rise. When the first motor 421 is in the second working state, the first motor 421 rotates reversely, thereby driving the reel 412 to reversely unwind the pull rope 411. After the pull rope 411 is unwound, the pull rope 411 removes the tension applied to the connecting assembly 30. At this time, the gravity acting on the cleaning assembly 20 is greater than the external force applied by the connecting assembly 30 on the cleaning assembly 20, thereby causing the cleaning assembly 20 to descend in the height direction.

[0066] In some embodiments, the connecting assembly 30 includes a support block 311. A slide groove 3111 is provided on one of the cleaning assembly 20 and the support block 311, and a first guide rail 21 adapted to the slide groove 3111 is provided on the other of the cleaning assembly 20 and the support block 311. The first guide rail 21 is disposed in the slide groove 3111 so that the cleaning assembly 20 can reciprocate in a first direction relative to the support block 311. The pulling portion 41 is inserted into the support block 311.

[0067] In a specific embodiment, a slide groove 3111 is provided on the support block 311, and a slide rail is provided on the cleaning assembly 20. The first guide rail 21 moves in the slide groove 3111, so that the cleaning assembly 20 can reciprocate in a first direction relative to the support block 311. In this embodiment, one end of the pull rope 411 is passed through the support block 311. Regardless of whether the cleaning assembly 20 is expanding, the cleaning assembly 20 can drive the reel 412 via the first motor 421 to reel in the pull rope 411, thereby lifting the cleaning assembly 20. In addition, the support block 311 is stationary relative to the cleaning assembly 20 in the first direction. Therefore, when the cleaning assembly 20 is expanding, the support block 311 and the pull rope 411 will not move in the first direction along with the cleaning assembly 20, thereby preventing the pull rope 411 from interfering with other components of the cleaning device.

[0068] Furthermore, the cleaning device also includes at least two first limiting portions 60 , wherein at least one first limiting portion 60 is arranged between the connecting assembly 30 and the main body 10 , and at least one first limiting portion 60 is arranged between the second driving assembly 50 and the main body 10 .

[0069] Specifically, in this embodiment, the first limiting portion 60 has a limiting effect on the lifting and lowering of the connecting component 30 and the second driving component 50, that is, preventing the connecting component 30 and the second driving component 50 from rising or falling too much, thereby causing the connecting component 30 and the second driving component 50 to interfere with other components of the cleaning device.

[0070] As attached Figure 9As shown, the first limiting portion 60 includes a fixing plate 61, a first rod 62, a second rod 63, and a torsion spring 64. The fixing plate 61 is connected to the main body 10. The second rod 63 is spaced apart from the first rod 62 in the height direction. The first end of the first rod 62 and the first end of the second rod 63 are both rotatably connected to the fixing plate 61. The second end of the first rod 62 and the second end of the second rod 63 are both connected to the connecting assembly 30 or the second driving assembly 50. The torsion spring 64 is sleeved on the first end of the first rod 62. The first end of the torsion spring 64 abuts against the fixing plate 61, and the second end of the torsion spring 64 passes through the first rod 62 and abuts against the second rod 63.

[0071] Specifically, when the cleaning component 20 rises, the connecting component 30 and the second driving component 50 rise with the cleaning component 20. At this time, the first rod 62 and the second rod 63 connected to the connecting component 30 or the second driving component 50 rotate, thereby causing the torsion spring 64 to be compressed. When the torsion spring 64 is compressed to a certain extent, the external force applied by the torsion spring 64 to the first rod 62 and the second rod 63 is too large, and the connecting component 30 or the second driving component 50 stops rising under the external force of the torsion spring 64 to prevent the connecting component 30 or the second driving component 50 from colliding with other components of the cleaning device. When the cleaning assembly 20 descends, the torsion spring 64 releases its elastic force, causing the first rod 62 and the second rod 63 to rotate in opposite directions. The cleaning assembly 20 or the second driving assembly 50 descends under the action of gravity and the external forces exerted by the first rod 62 and the second rod 63. When the connecting assembly 30 descends to a certain extent, the first rod 62 and the second rod 63 exert a pulling force on the connecting assembly 30, thereby preventing the connecting assembly 30 from continuing to descend. At this time, the cleaning assembly 20 stops descending under the action of the connecting assembly 30. In this embodiment, the first rod 62, the second rod 63, the torsion spring 64, and the fixing plate 61 form a four-bar linkage structure, thereby ensuring that the support block 311 or the gear mounting housing 521 connected to the first limiting portion 60 can ascend or descend more smoothly.

[0072] Of course, in some embodiments, only one connecting rod may be provided on the first limiting portion 60, but the connection stability of one connecting rod with the fixing plate 61 and the support block 311 or the gear mounting housing 521 is obviously lower than that of the first rod 62 and the second rod 63 in this embodiment. Figure 10 As shown, in some embodiments, the first limiting portion 60 includes three connecting rods spaced apart along the height direction, the first ends of the three connecting rods are connected to the fixing plate 61, and the second ends of the three connecting rods are connected to the support block 311 or the gear mounting shell 521, thereby increasing the connection stability with the support block 311 or the gear mounting shell 521.

[0073] In some embodiments, a rack 22 is provided on the cleaning assembly 20, and the rack 22 extends along the first direction; the second drive assembly 50 includes a second drive part 51 and a gear connecting part 52, and the gear connecting part 52 is connected to the output end of the second drive part 51. The gear connecting part 52 cooperates with the rack 22 to make the cleaning assembly 20 reciprocate along the first direction.

[0074] Specifically, the second driving portion 51 is used to drive the gear connecting portion 52 to rotate. The gear connecting portion 52 rotates, thereby driving the rack 22 to cause the cleaning assembly 20 to reciprocate along the first direction. Of course, the cleaning assembly 20 may also be provided with a groove, and the second driving assembly 50 may also include a protrusion adapted to the groove, the protrusion being inserted into the groove. When the second driving portion 51 drives the protrusion to reciprocate along the first direction, the protrusion cooperates with the groove, thereby causing the cleaning assembly 20 to reciprocate along the first direction.

[0075] Furthermore, the gear connecting portion 52 includes a gear mounting housing 521 and a gear 522. The gear 522 is mounted within the gear mounting housing 521 and meshes with the rack 22. The second driving portion 51 includes a second motor 511. The second motor 511 is fixedly connected to the gear mounting housing 521. The output end of the second motor 511 is disposed within the gear mounting housing 521 and connected to the gear 522. The gear mounting housing 521 is connected to the first limiting portion 60.

[0076] Specifically, when the second motor 511 rotates forward, the gear 522 has a first rotational state, at which time the rack 22 meshing with the gear 522 causes the cleaning assembly 20 to move in a first direction under the action of the gear 522. When the second motor 511 rotates reversely, the gear 522 has a second rotational state, at which time the rack 22 meshing with the gear 522 causes the cleaning assembly 20 to move in a direction opposite to the first direction under the action of the gear 522. In this embodiment, the gear mounting housing 521 is used to protect the gear 522 and prevent the gear 522 from contacting other components of the cleaning device, causing damage to the gear 522. In addition, the second motor 511 is fixed to the gear mounting housing 521, and the gear mounting housing 521 is connected to the main body 10 via the first limiter 60, thereby enabling the second motor 511 to be raised and lowered in the height direction of the main body 10. The first limiter 60 can prevent the second motor 511 from rising or falling too much, causing the second motor 511 to interfere with other components of the cleaning device.

[0077] As attached Figure 10 As shown, the cleaning assembly 20 includes a support frame 201 and a cleaning member 202. The support frame 201 is provided with a mounting groove, and the connecting assembly 30 and the rack 22 are both arranged on the upper surface of the support frame 201. The cleaning member 202 is rotatably mounted in the mounting groove.

[0078] Specifically, the bottom of the support frame 201 is provided with a mounting slot, into which the cleaning member 202 is mounted. The top of the support frame 201 is provided with a support block 311 and a rack 22. When the second motor 511 drives the gear 522 to rotate, the gear 522 cooperates with the rack 22, thereby causing the support frame 201 to reciprocate in the first direction. Simultaneously, the first guide rail 21 on the support frame 201 cooperates with the support block 311, thereby preventing the support block 311 from applying external force to the support frame 201, thereby preventing the support frame 201 from reciprocating in the first direction. In this embodiment, the cleaning member 202 is a cleaning roller. Alternatively, the cleaning member 202 may be a roller brush.

[0079] As attached Figure 13 To the attached Figure 14 As shown, the cleaning assembly 20 is provided with a rack 22 , and the second driving assembly 50 includes a gear connecting portion 52 , the gear connecting portion 52 is provided with a guide groove 5211 , the guide groove 5211 extends along the first direction, and the rack 22 is movably provided in the guide groove 5211 .

[0080] Specifically, the guide groove 5211 is provided at the bottom of the gear connecting portion 52. The guide groove 5211 is used to avoid and guide the rack 22. On the one hand, it prevents the rack 22 from colliding with the gear connecting portion 52 when moving along the first direction; on the other hand, when the rack 22 and the cleaning assembly 20 tilt in the first direction, the guide groove 5211 can exert a certain supporting force on the rack 22 and the cleaning assembly 20, thereby enabling the rack 22 and the cleaning assembly 20 to turn to reciprocating motion along the first direction under the action of the supporting force.

[0081] In addition, a limiting fitting portion 23 is provided on the cleaning assembly 20 , and a second limiting portion 5212 adapted to the limiting fitting portion 23 is provided on the side wall of the guide groove 5211 .

[0082] Specifically, a second limiting portion 5212 is provided on the side wall of the guide groove 5211, and the second limiting portion 5212 cooperates with the limiting cooperation portion 23, so that when the cleaning component 20 moves in the first direction, the cleaning component 20 can be limited in the guide groove 5211, thereby preventing the cleaning component 20 from being affected by external force and deviating from the first direction.

[0083] Furthermore, one of the limiting matching portion 23 and the second limiting portion 5212 is a limiting groove 5213 , and the other is a limiting protrusion 231 matched with the limiting groove 5213 .

[0084] As attached Figure 12 To the attached Figure 14As shown, in a specific embodiment, the second limiting portion 5212 is a limiting groove 5213, the limiting matching portion 23 is a limiting protrusion 231, and in this embodiment, the limiting groove 5213 includes two, the two limiting grooves 5213 are respectively opened on the two opposite side walls of the guide groove 5211, and the limiting protrusion 231 also includes two, the two limiting protrusions 231 and the two limiting grooves 5213 are respectively arranged on both sides of the cleaning component 20, and correspond one-to-one to the two limiting grooves 5213.

[0085] Furthermore, the connecting assembly 30 and the rack 22 are spaced apart along the first direction.

[0086] In this embodiment, the support block 311 and the rack 22 are arranged on the support frame 201 at intervals along the first direction. When the support frame 201 reciprocates along the first direction, the support block 311 can exert a certain supporting force on the support frame 201, so that the support frame 201 is more stable when expanding outward, thereby preventing the end of the support frame 201 connected to the support block 311 from being offset in the height direction when the support frame 201 expands outward.

[0087] In summary, in the cleaning device of the present application, a connecting assembly 30 is provided on the cleaning assembly 20, and the cleaning assembly 20 can reciprocate along a first direction relative to the connecting assembly 30; at the same time, the first driving assembly 40 can apply an external force to the connecting assembly 30, so that the connecting assembly 30 drives the cleaning assembly 20 to rise or fall, and the second driving assembly 50 can make the cleaning assembly 20 protrude from the outer edge of the main body 10 relative to the connecting assembly 30 or make the cleaning assembly 20 retracted inside the main body 10, thereby making the cleaning assembly 20 expand and rise and fall at any time, thereby improving the applicable scenarios of the cleaning device to a certain extent. On the other hand, the first driving assembly 40 includes a pull rope 411, a first motor 421 and a winding wheel 412, and the connecting assembly 30 includes a support block 311, which is used to reel in or unreel the pull rope 411 to make the support block 311 and the cleaning assembly 20 rise or fall. In addition, the present application also provides a first limiting portion 60 on the connecting component 30 and the second driving component 50, respectively. The first limiting portion 60 enables the connecting component 30 and the second driving component 50 to rise or fall with the cleaning component 20, so that the cleaning component 20 can expand outward when rising or falling; at the same time, the first limiting portion 60 limits the rise or fall of the connecting component 30 and the second driving component 50, thereby preventing the connecting component 30 and the second driving component 50 from interfering with other components of the cleaning device. Finally, in the present application, the connecting component and the rack 22 are spaced apart along the first direction at both ends of the cleaning component 20, so that when the cleaning component 20 expands outward, there are force points at both ends, thereby preventing one end of the cleaning component 20 from offsetting in the height direction when the cleaning component 20 expands outward.

[0088] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0089] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0090] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
