Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0045] See also Figures 1 to 13 As shown, according to an embodiment of the present application, a cleaning device is provided, which includes a main body 10, a cleaning assembly 20 and a driving mechanism 30.

[0046] The cleaning assembly 20 is disposed at the bottom of the main body 10, and the cleaning assembly 20 is disposed along the height direction of the main body 10 (such as the attached Figure 2 The cleaning assembly 20 is arranged to be lifted and lowered in the middle Z direction, and has a first position protruding from the outer side of the main body 10 and a second position retracted inside the main body 10. The driving mechanism 30 is arranged between the main body 10 and the cleaning assembly 20 to drive the cleaning assembly 20 to be lifted and lowered, and at the same time drive the cleaning assembly 20 to switch between the first position and the second position.

[0047] The cleaning device in this embodiment can be, for example, a sweeper, a scrubber, or a base station with a sweeper or a scrubber. The cleaning component 20 can be a mop 22 or a side sweeping brush. Specifically, in this embodiment, the driving mechanism 30 can drive the cleaning component 20 to rise and fall in the height direction of the cleaning device, and at the same time drive the cleaning component 20 to switch between the first position and the second position, that is, there are the following two modes: the cleaning component 20 is in the first position when it descends and the cleaning component 20 is in the second position when it rises; the cleaning component 20 is in the first position when it rises and the cleaning component 20 is in the second position when it descends.

[0048] Compared with the prior art, the driving mechanism 30 in this embodiment is arranged between the main body 10 and the cleaning component 20 to drive the cleaning component 20 to rise and fall, and at the same time drive the cleaning component 20 to switch between the first position and the second position. The lifting of the cleaning component 20 can enable the cleaning device to cross obstacles when cleaning the floor, and the cleaning component 20 can switch between the first position and the second position so that the cleaning device has the ability to clean along the edge, thereby improving the cleaning effect of the cleaning device.

[0049] In a preferred embodiment, the cleaning assembly 20 is in the first position when it descends, and in the second position when it rises. When the cleaning assembly 20 can protrude from the outer side of the main body 10 after it descends, there is a certain distance between the cleaning assembly 20 and the main body 10, and at this time, the cleaning assembly 20 is in contact with the ground, thereby avoiding interference between the cleaning assembly 20 and the main body 10 during cleaning. In addition, when the cleaning assembly 20 protrudes from the main body 10, it can clean corners such as wall corners. When the cleaning assembly 20 is blocked by an obstacle, the driving mechanism 30 drives the cleaning assembly 20 to rise and then retracts it inside the main body 10, and the cleaning assembly 20 is separated from the ground, and the obstacle cannot exert external force on the cleaning assembly 20, so that the cleaning device can cross the obstacle.

[0050] Of course, in some embodiments, the cleaning component 20 may be in the second position when descending and in the first position when rising. For example, when the cleaning component 20 is a side sweeping brush, when the side sweeping brush descends, the side sweeping brush is in contact with the ground to clean the ground, and when the side sweeping brush rises, the side sweeping brush is separated from the ground and protrudes from the cleaning device, which is suitable for cleaning the side wall surfaces of corners.

[0051] Further, the driving mechanism 30 includes a guide portion 32, a sliding portion 31 and a driving assembly 33. The guide portion 32 is fixedly arranged on the main body 10. The sliding portion 31 is slidably arranged on the guide portion 32, and the sliding portion 31 is fixedly connected to the cleaning assembly 20. The driving assembly 33 is arranged on the main body 10, and the driving assembly 33 is connected to the sliding portion 31 to drive the sliding portion 31 to rise and fall, and at the same time drive the sliding portion 31 to reciprocate along the first direction. When the driving assembly 33 drives the sliding portion 31 to descend, it simultaneously drives the cleaning assembly 20 to switch from the second position to the first position; when the driving assembly 33 drives the sliding portion 31 to rise, it simultaneously drives the cleaning assembly 20 to switch from the first position to the second position.

[0052] Specifically, as attached Figure 4 , Attachment Figure 5 and attached Fig.13 As shown, the cleaning assembly 20 includes a bottom plate 21 and a mop 22, the mop 22 is sleeved on the bottom plate 21, one end of the sliding part 31 is fixedly connected to the bottom plate 21, when the sliding part 31 slides along the first direction, the sliding part 31 drives the bottom plate 21 to switch from the second position to the first position, so that the mop 22 protrudes from the outer edge of the main body 10 to clean the floor. When the sliding part 31 slides in the direction opposite to the first direction under the drive assembly 33, the sliding part 31 drives the bottom plate 21 to switch from the first position to the second position, at which time the mop 22 and the bottom plate 21 are lifted to a certain height and are not in contact with the floor.

[0053] In addition, the guide portion 32 and the sliding portion 31 each include one or more. When the guide portion 32 and the sliding portion 31 each include multiple guide portions 32 and multiple sliding portions 31 correspond to each other one by one and are arranged along the first direction (such as the attached Figure 4 In a specific embodiment, the guide portion 32 and the sliding portion 31 each include two, and the two guide portions 32 and the two sliding portions 31 are spaced apart and arranged in a one-to-one correspondence along the first direction. Since the bottom plate 21 is relatively long, the present embodiment is connected to the bottom plate 21 through two sliding portions 31, thereby improving the connection strength between the sliding portion 31 and the bottom plate 21.

[0054] At this time, an installation cavity 101 is set in the main body 10, and the guide part 32 includes a wedge block 321, which is fixedly set in the installation cavity 101 and extends along the first direction. The surface of the wedge block 321 away from the cleaning component 20 is a slope 3211, and the slope 3211 is inclined along the height direction of the main body 10. The sliding part 31 is slidably set on the slope 3211.

[0055] Specifically, the main body 10 includes a mounting plate 11 and an upper cover 12, wherein the upper cover 12 is disposed on the mounting plate 11 and surrounds the mounting cavity 101. When the driving assembly 33 drives the sliding portion 31 to slide from the top of the wedge block 321 to the bottom of the wedge block 321, the cleaning assembly 20 is driven by the sliding portion 31 to descend in a direction opposite to the height direction, and the cleaning assembly 20 is switched from the second position to the first position, at which time the cleaning assembly 20 can clean the ground. When the driving assembly 33 drives the sliding portion 31 to slide from the bottom of the wedge block 321 to the top of the wedge block 321, the cleaning assembly 20 is driven by the sliding portion 31 to rise in the height direction, and the cleaning assembly 20 is switched from the first position to the second position, at which time there is a certain distance between the cleaning assembly 20 and the ground, so that the cleaning assembly can avoid obstacles. In this embodiment, the cross-sectional area of ​​the wedge block 321 gradually decreases along the first direction. The cross-sectional area of ​​the wedge block 321 refers to the surface obtained by intercepting the wedge block 321 by a plane perpendicular to the first direction, thereby ensuring that when the sliding part 31 slides along the first direction, the cleaning component 20 switches from the second position to the first position.

[0056] Further, the main body 10 is located in the width direction of the wedge block 321 (such as the attached Fig.12 Avoidance gaps 111 are provided on both sides (in the middle X direction), and the avoidance gaps 111 are connected to the installation cavity 101; the sliding portion 31 includes a slider 311, the slider 311 is installed in the installation cavity 101, and a slide groove 3111 is provided on the slider 311, the wedge block 321 is located in the slide groove 3111, and the opposite sides of the slider 311 pass through the avoidance gaps 111 to be connected to the cleaning component 20.

[0057] In this embodiment, the slider 311 is arranged in a U-shape, and the U-shaped opening of the slider 311 forms a slide groove 3111, and the slide groove 3111 is buckled on the wedge block 321, and both ends of the U-shaped opening of the slider 311 pass through the avoidance notch 111 and are connected to the cleaning assembly 20, so that the slider 311 can slide on the wedge block 321 without interfering with the main body 10. In this embodiment, the extension direction of the avoidance notch 111 is consistent with the first direction. In addition, the extension length of the avoidance notch 111 can also limit the sliding range of the slider 311.

[0058] Furthermore, a limiting portion 40 is disposed on the wedge block 321 , and the limiting portion 40 is disposed at two ends of the inclined surface 3211 along the first direction.

[0059] Specifically, the limiting portion 40 on the wedge block 321 is used to limit the sliding range of the slider 311. If the slider 311 slides too far from the bottom of the wedge block 321 to the top of the wedge block 321, the cleaning assembly 20 may rise too far, thereby causing interference between the cleaning assembly 20 and the main body 10. When the slider 311 slides from the top of the wedge block 321 to the bottom of the wedge block 321, if the limiting portion 40 is not provided, the cleaning assembly 20 may fall too far, causing the cleaning assembly 20 to exert too much pressure on the ground, thereby causing the cleaning assembly 20 to lock and fail to work normally, and may also cause the slider 311 to detach from the wedge block 321, ultimately making it impossible for the cleaning assembly 20 to switch between the first position and the second position.

[0060] Further, the limiting portion 40 includes a limiting protrusion 41 and / or a limiting baffle 42 , and the limiting protrusion 41 and / or the limiting baffle 42 protrude from the inclined surface 3211 .

[0061] It should be noted that “the limiting portion 40 includes the limiting protrusion 41 and / or the limiting baffle 42” means that the limiting portion 40 includes one of the three situations: the limiting protrusion 41, the limiting baffle 42, and the limiting protrusion 41 and the limiting baffle 42. Similarly, “the limiting protrusion 41 and / or the limiting baffle 42 protrude from the inclined surface 3211” means that the limiting protrusion 41 protrudes from the inclined surface 3211, the limiting baffle 42 protrudes from the inclined surface 3211, and the limiting protrusion 41 and the limiting baffle 42 protrude from the inclined surface 3211. In this embodiment, the limiting portion 40 includes the limiting protrusion 41 and the limiting baffle 42, and both the limiting protrusion 41 and the limiting baffle 42 protrude from the inclined surface 3211.

[0062] Furthermore, the limiting portion 40 is disposed on the top of the wedge block 321 , and the limiting portion 40 extends downward by a predetermined length along the inclined direction of the inclined surface 3211 .

[0063] As attached Fig.12As shown, in a specific embodiment, the limiting portion 40 disposed on the top of the wedge block 321 is a limiting protrusion 41, which extends downward by a predetermined length along the inclined direction of the inclined surface 3211, that is, the limiting protrusion 41 extends from the top of the wedge block 321 along the inclined direction of the inclined surface 3211 to the bottom of the wedge block 321 by a certain length, thereby limiting the sliding of the slider 311. The limiting portion 40 disposed at the bottom of the wedge block 321 is a limiting baffle 42, which extends along the height direction of the main body 10, thereby preventing the slider 311 from detaching from the wedge block 321.

[0064] Furthermore, the driving assembly 33 includes an elastic member 331, which is arranged between the sliding part 31 and the guide part 32 and / or between the sliding part 31 and the main body 10, and the extension direction of the elastic member 331 is consistent with the first direction or the inclination direction of the inclined surface 3211.

[0065] Specifically, "the elastic member 331 is arranged between the sliding part 31 and the guide part 32 and / or the elastic member 331 is arranged between the sliding part 31 and the main body 10" refers to one of the three situations that the elastic member 331 is arranged between the sliding part 31 and the guide part 32, the elastic member 331 is arranged between the sliding part 31 and the main body 10, and the elastic member 331 is arranged between the sliding part 31 and the guide part 32 and between the sliding part 31 and the main body. When the elastic member 331 is arranged between the sliding part 31 and the guide part 32, after the driving mechanism 30 drives the cleaning component 20 to rise, the elastic member 331 is compressed, and at this time, the elastic member 331 applies a certain elastic force to the sliding part 31 to prevent the sliding part 31 from colliding with the limiting protrusion 41; after the driving mechanism 30 removes the external force applied to the cleaning component 20, the elastic member 331 applies elastic force to the sliding part 31, so that the sliding part 31 descends along the inclined surface 3211, and finally the cleaning component 20 descends. When the elastic member 331 is arranged between the main body 10 and the sliding part 31, after the cleaning component 20 descends, the elastic member 331 is compressed. At this time, the elastic member 331 applies a certain elastic force to the sliding part 31, thereby preventing the sliding part 31 from continuing to descend along the inclined surface 3211, and finally causing the sliding part 31 to collide with the limit baffle 42; on the other hand, after the driving mechanism 30 removes the external force applied to the cleaning component 20, the elastic member 331 gradually returns to its original state from the extended state. At this time, the elastic member 331 applies a certain pulling force to the sliding part 31, thereby driving the sliding part 31 to move downward along the inclined surface 3211.

[0066] In a specific embodiment, as shown in the attached Figure 7As shown, the elastic member 331 is a spring 3331, and the spring 3331 includes a plurality of springs, at least one of which is disposed between the slider 311 and the wedge block 321, and at least one of which is disposed between the slider 311 and the main body 10. Specifically, when the cleaning assembly 20 is located at the first position, the elastic force applied to the sliding portion 31 by the spring 3331 disposed between the slider 311 and the wedge block 321 is greater than the elastic force applied to the slider 311 by the spring 3331 disposed between the slider 311 and the main body 10, so that the slider 311 is pressed against a position close to the limiting baffle 42, thereby preventing the slider 311 from sliding on the wedge block 321 when the cleaning assembly 20 is subjected to an external force. Of course, when the cleaning component 20 is in the first position, the elastic force applied by the spring 3331 between the slider 311 and the wedge block 321 to the sliding portion 31 can be the same as the elastic force applied by the spring 3331 between the slider 311 and the main body 10 to the slider 311. At this time, if the cleaning component 20 is subjected to an external force in the opposite direction to the first direction or an external force in the opposite direction to the inclination direction of the inclined surface 3211, the cleaning component 20 can rise a certain distance, so that the cleaning component 20 can cross the obstacle.

[0067] Of course, the spring 3331 may also be disposed only between the sliding portion 31 and the guide portion 32, or the spring 3331 may be disposed only between the sliding portion 31 and the main body. In addition, the elastic member 331 in this embodiment may also be extended in other directions, as long as the elastic force component applied by the spring 3331 to the slider 311 can generate a component force in the inclined direction of the inclined surface 3211.

[0068] In addition, as attached Figure 7 As shown, a guide channel 3212 is provided at the top of the wedge block 321, and the extension direction of the guide channel 3212 is consistent with the inclination direction of the inclined surface 3211. The driving assembly 33 also includes a driving member 332 and a pull rope 333. The driving member 332 is arranged in the installation cavity 101. The first end of the pull rope 333 is connected to the driving member 332, and the second end of the pull rope 333 passes through the guide channel 3212 and is connected to the sliding part 31. The pull rope 333 is driven by the driving member 332 to pull the sliding part 31 to slide along the inclination direction of the inclined surface 3211.

[0069] Specifically, as attached Fig.12As shown, the extension direction of the guide channel 3212 is from the top of the wedge block 321 along the inclined direction of the inclined surface 3211 to the bottom of the wedge block 321, and the pull rope 333 passes through one end of the guide channel 3212 near the top of the wedge block 321 and is connected to the slider 311. When the driving member 332 drives the pull rope 333, the pull rope 333 pulls the slider 311 to move upward along the inclined direction of the inclined surface 3211, so that the cleaning component 20 rises and switches from the second position to the first position, and when the driving member 332 is not working, the pull rope 333 is relaxed, and at this time, the spring 3331 set between the slider 311 and the wedge block 321 applies an elastic force to the slider 311 in the downward direction along the inclined surface 3211 or the spring 3331 between the slider 311 and the main body applies a pulling force to the slider 311, so that the slider 311 moves downward along the inclined direction of the inclined surface 3211, and at this time, the cleaning component 20 descends and moves from the second position to the first position.

[0070] In this embodiment, the driving member 332 is a motor 3321. When the motor 3321 rotates, the pull rope 333 is retracted, so that the pull rope 333 can apply tension to the slider 311. In this embodiment, the pull rope 333 includes two pull ropes, and the two pull ropes 333 are respectively connected to the two sliders 311. When the motor 3321 rotates, the two pull ropes 333 are tightened at the same time, so that the two pull ropes 333 apply tension to the two sliders 311 at the same time, so that the overall rising height of the cleaning component 20 is consistent.

[0071] In other embodiments, for example, when the cleaning component 20 is a side sweeping brush, the driving component 33 does not need to be provided with a motor 3321 and a pull rope 333. The side sweeping brush can be switched between the first position and the second position only by setting the initial elastic force of the spring 3331. That is, when the external force exerted by the obstacle on the side sweeping brush is greater than the external force exerted by the spring on the side sweeping brush, the side sweeping brush can slide on the wedge block 321 to avoid the obstacle.

[0072] Furthermore, along the height direction of the main body 10 , a protective gap 50 is provided between the cleaning assembly 20 and the main body 10 , and a width A of the protective gap 50 is not less than 1 mm.

[0073] Specifically, in order to avoid interference between the cleaning component 20 and the main body 10 after the cleaning component 20 rises, a protective gap 50 is provided between the cleaning component 20 and the main body 10, and the width of the protective gap 50 cannot be too small, that is, A is greater than or equal to 1mm. If the width of the protective gap 50 is too small, it is easy to cause interference between the cleaning component 20 and the main body 10. In addition, when the cleaning component 20 moves from the second position to the first position, the maximum distance of the protective gap 50 does not exceed 11mm to prevent the cleaning component 20 from being stuck by the ground and unable to work normally. When the cleaning component 20 switches between the first position and the second position, the width A of the protective gap 50 can be 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm and 11mm.

[0074] In addition, in this embodiment, the motor 3321 is a lifting motor, and one end of the pull rope 333 is wound around the lifting motor. When the lifting motor rotates clockwise, the extended part of the pull rope 333 is retracted by the lifting motor, so that the pull rope 333 pulls the slider 311 to move upward along the inclined surface 3211; when the lifting motor rotates counterclockwise, the pull rope 333 is relaxed, so that the tension applied by the pull rope 333 to the slider 311 disappears, so that the slider 311 moves downward along the inclined surface 3211 under the elastic force of the spring 3331. In addition, when the external force applied by the obstacle to the outer expansion part of the cleaning component 20 in the direction opposite to the first direction is too large, the external force overcomes the elastic force applied by the spring 3331, so that the cleaning component 20 is lifted to a certain height and then crosses the obstacle. At the same time, the driving mechanism 30 in this embodiment has a simple structure, and the driving mechanism 30 will not interfere with the other components of the cleaning device, thereby improving the service life of the cleaning device to a certain extent.

[0075] In summary, the present application has the following beneficial effects: the cleaning device can simultaneously realize the outward expansion and lifting of the cleaning component 20, so that when the cleaning device is mopping the floor normally, the cleaning component 20 expands outward to cover a wide range along the edge of the mopping, and the cleaning effect of the cleaning device is better than that of the prior art. In addition, when the cleaning device encounters an obstacle, the outward expansion part of the cleaning component 20 is squeezed and passively lifted, thereby preventing the obstacle from damaging the cleaning component 20. Secondly, the cleaning device can also actively lift the cleaning component 20. For example, after the cleaning device stops working, in order to avoid friction between the cleaning component 20 and the ground, the cleaning component 20 will be lifted off the ground under the action of the motor 3321.

[0076] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. 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 figure. For example, if the device in the accompanying 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.

[0077] 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.

[0078] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
