DETAILED DESCRIPTION

[0047] ​In the following description, numerous specific details are set forth in order to provide a thorough understanding of the technical solutions provided by the present application. It will be apparent, however, to one skilled in the art that the technical solutions provided by the present application can be practiced without one or more of these specific details.

[0048] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, the singular forms are intended to include the plural forms, unless the context clearly indicates otherwise. In addition, it should also be understood that the terms "comprise" and / or "include" used in the specification indicate the presence of the stated features, integers, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or combinations thereof.

[0049] Exemplary embodiments according to the present application will now be described in detail with reference to the accompanying drawings. However, the exemplary embodiments can be implemented in various different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that the embodiments are provided so that the disclosure of the present application is complete and complete, and the concepts of the exemplary embodiments are sufficiently conveyed to those of ordinary skill in the art.

[0050] As shown in Figures 1 to 13 Embodiments of the first aspect of the present application provide a cleaning assembly 200, embodiments of the second aspect of the present application provide a cleaning module 300, and embodiments of the third aspect of the present application provide a cleaning device. Among them, the cleaning assembly 200 is applied to the cleaning module 300, the cleaning module 300 is applied to the cleaning device, and the cleaning device can be a floor cleaning robot, a sweeping and mopping integrated machine, a maintenance machine, or other cleaning devices that meet the requirements. For the convenience of description, in the following embodiments, the cleaning operation and the maintenance operation are collectively referred to as the cleaning operation.

[0051] Specifically, the cleaning device includes but is not limited to a machine body, a cleaning system, a walking system, etc. The above-mentioned systems cooperate with each other to enable the cleaning device to move autonomously to achieve the cleaning function. The functional elements constituting the above-mentioned systems in the cleaning device are integrally arranged in the machine body. The machine body is used to install and support other components of the cleaning device. It can be understood that the cleaning device can be a self-moving cleaning device, wherein the self-moving cleaning device is a device that automatically performs cleaning operation in a certain cleaning area without user operation.

[0052] Among them, the cleaning system can include a wet cleaning system, i.e. the cleaning device can be a floor cleaning robot or a maintenance robot; or the cleaning system can include a wet cleaning system and a dry cleaning system, i.e. the cleaning device can be a sweeping and mopping integrated machine, etc.

[0053] As shown in Figure 1 , the wet cleaning system can include a cleaning module 300, the cleaning module 300 including a cleaning assembly 200, which can be used for mopping, washing, or waxing, etc.

[0054] The dry cleaning system can include a rolling brush, a dust box, and a suction fan. The rolling brush with a certain interference with the ground sweeps the garbage on the ground and brings it to the front of the suction port between the rolling brush and the dust box, and then the garbage is sucked into the dust box by the suction gas generated by the suction fan.

[0055] Further, the dry cleaning system can further include a side brush assembly rotatably connected with the machine body, for moving debris and other sundries outside the rolling brush area into the rolling brush area of the cleaning system.

[0056] Further, as shown in Figure 1 , the cleaning module 300 provided by the embodiment of the present application further includes a lifting device 100 connected with the cleaning assembly 200, and the lifting device 100 is further configured to be connected with the machine body of the cleaning device, and the lifting device 100 is configured to drive the cleaning assembly 200 to switch between the raised position and the lowered position relative to the machine body. In this way, when the cleaning module 300 needs to work, such as when the walking surface is an area that needs to be mopped, washed, or waxed, the lifting device 100 drives the cleaning assembly 200 to be in the lowered position, i.e., the cleaning assembly 200 is in the working position, so that the cleaning assembly 200 can interfere with the walking surface to perform cleaning operation. When the cleaning module 300 does not need to work, such as when the walking surface is an area that does not need to be mopped, washed, or waxed, such as a carpet area, the lifting device 100 drives the cleaning assembly 200 to be in the raised position, i.e., the cleaning assembly 200 is in the initial position, so that the cleaning assembly 200 has a certain distance from the walking surface, and the cleaning assembly 200 does not interfere with the walking surface and does not perform cleaning operation on the walking surface. Wherein, the raised direction of the cleaning assembly 200 is shown by the arrow Z+ in Figures 1 to 3 , Figures 8 to 13 , and the lowered direction of the cleaning assembly 200 is shown by the arrow Z- in Figures 1 to 3 , Figures 8 to 13 .

[0057] In actual application scenarios, the cleaning assembly may wet or dirty the area that does not need to be cleaned, such as a carpet, due to moisture or attached garbage, such as the garbage attached to the cleaning assembly 200 falling on the area that does not need to be mopped, washed, or waxed, causing pollution, or due to the long hair of the carpet, when the cleaning device runs to the carpet area, the hair of the carpet may contact the cleaning assembly 200 in the initial position, thereby wetting or dirtying the carpet and causing pollution.

[0058] To this end, as shown in Figure 2 and Figure 3 the first aspect of the present application, an embodiment provides a cleaning assembly 200, comprising: a mounting frame 210; a cleaning element 220, the cleaning element 220 being connected to the mounting frame 210; a shielding piece 230, the shielding piece 230 being movably arranged relative to the cleaning element 220 and switchable between a first position and a second position, in the first position the shielding piece 230 at least shields a bottom edge of the cleaning element 220, and in the second position the shielding piece 230 at least exposes the bottom edge of the cleaning element 220.

[0059] The cleaning assembly 200 provided by the embodiment of the present application comprises the mounting frame 210, the cleaning element 220 and the shielding piece 230, wherein the cleaning element 220 is connected to the mounting frame 210, and the mounting frame 210 plays a good supporting role for the cleaning element 220. It can be understood that the cleaning element 220 is configured to interfere with the walking surface to perform a cleaning operation on the walking surface. The shielding piece 230 is movably arranged relative to the cleaning element 220, and the relative position of the shielding piece 230 and the cleaning element 220 includes the first position and the second position.

[0060] As shown in Figure 2 , in the first position, the shielding piece 230 at least shields the bottom edge of the cleaning element 220, that is, the bottom edge of the cleaning element 220 and the walking surface are separated by the shielding piece 230. Therefore, it can reduce or avoid the possibility that the cleaning assembly 200 will wet or dirty the area that does not need to be mopped, cleaned or waxed due to moisture or attached garbage. For example, the garbage attached to the cleaning element 220 will fall on the shielding piece 230 and will not fall on the walking surface, and the carpet hair will contact the shielding piece 230 and will not contact the cleaning element 220. Therefore, the possibility of the walking surface being contaminated by the cleaning element 220 is reduced, the cleanliness of the walking surface is improved, the overall cleaning effect of the cleaning equipment is improved, and the user's satisfaction is improved. The bottom edge of the cleaning element 220 can be understood as the edge of the cleaning element 220 facing the Z-direction.

[0061] As shown in Figure 3 , in the second position, the shielding piece 230 at least exposes the bottom edge of the cleaning element 220, that is, the bottom edge of the cleaning element 220 and the walking surface are not shielded by the shielding piece 230, and are opposite to each other. Therefore, the need for the cleaning assembly 200 to mop, clean or wax the walking surface can be met. For example, the lifting device 100 drives the cleaning assembly 200 to move from the raised position to the lowered position, so that the cleaning assembly 200 can be used to mop, clean or wax the walking surface.

[0062] That is, the cleaning assembly 200 provided by the embodiment of the present application can meet the different operation requirements of the cleaning assembly 200 for cleaning the walking surface and the cleaning assembly 200 not needing to clean the walking surface and actively shielding the bottom edge of the cleaning element 220 by the shielding element 230, by arranging the shielding element 230, which moves between the first position and the second position relative to the cleaning element 220, thereby expanding the use range of the cleaning assembly 200. At the same time, when the shielding element 230 shields the bottom edge of the cleaning element 220, the bottom edge of the cleaning element 220 is separated from the walking surface, which can reduce the possibility of the walking surface being polluted by the cleaning element 220 and improve the cleanliness of the walking surface. At the same time, compared with shielding the cleaning element by arranging the shielding element on the machine body in the related art, the shielding element 230 can be reduced in size and space occupied, thereby saving space, meeting the design requirements of compact structure and small size of the cleaning equipment, and being suitable for popularization and application.

[0063] Wherein, the shielding element 230 moves from the second position to the first position along the forward direction, the forward direction being indicated by the arrow R+ shown in Figures 1 to 3 , the shielding element 230 moves from the first position to the second position along the reverse direction, the reverse direction being indicated by the arrow R- shown in Figures 1 to 3 .

[0064] Wherein, the cleaning element 220 is connected with the mounting frame 210, so that the cleaning element 220 and the mounting frame 210 can be regarded as a whole and move with the mounting frame 210. Specifically, the cleaning element 220 can be detachably connected with the mounting frame 210, so as to facilitate maintenance or replacement of the cleaning element 220 after the cleaning element 220 and the mounting frame 210 are detached, which is beneficial to improve the maintenance efficiency and save the maintenance cost.

[0065] Wherein, the shielding element 230 is movably arranged with the cleaning element 220, which can be that the shielding element 230 is movably connected with the mounting frame 210, so that the shielding element 230 can move relative to the cleaning element 220, or the shielding element 230 is movably connected with the machine body, so that the shielding element 230 can move relative to the cleaning element 220.

[0066] Wherein, the shielding element 230 is movably arranged relative to the cleaning element 220, which can be that the shielding element 230 is rotatably arranged, translatably arranged, or compoundly arranged by rotation and translation relative to the cleaning element 220, as long as the shielding element 230 can move relative to the cleaning element 220 and can be switched between the first position and the second position.

[0067] The cleaning element 220 can include a cleaning roller or a mop plate. The shielding piece 230 can be reasonably arranged to move relative to the cleaning element 220 and smoothly switch between the first position and the second position according to different types of the cleaning element 220.

[0068] As shown in Figure 2 and Figure 3 In some possible implementation embodiments provided by the present application, the shielding piece 230 is rotationally connected to the mounting frame 210, and rotates relative to the mounting frame 210 to switch between the first position and the second position.

[0069] In the embodiment, the shielding piece 230 is switched between the first position and the second position by rotation. The rotation facilitates reducing the space occupied by the shielding piece 230 during movement, so that the shielding piece 230, the cleaning element 220 and the mounting frame 210 can be compactly arranged, thereby meeting the design requirement of compact structure and small volume of the cleaning assembly 200, and being suitable for popularization and application.

[0070] As shown in Figure 4 In some possible implementation embodiments provided by the present application, the shielding piece 230 includes a main body part 231 and a connecting part 232 connected to each other. The connecting part 232 is rotationally connected to the mounting frame 210. The length direction of the main body part 231 is parallel to the length direction of the cleaning element 220, and the main body part 231 is located on part of the circumferential side of the cleaning element 220. Figures 1 to 3 The length direction of the cleaning element 220 can be parallel to the X+ and X- directions in

[0071] Therefore, the connecting part 232 rotates relative to the mounting frame 210, which can drive the main body part 231 to rotate relative to the cleaning element 220 and cover different parts of the circumferential side of the cleaning element 220, so as to switch the shielding piece 230 between the first position and the second position.

[0072] The length of the main body part 231 can be equal to or greater than the length of the cleaning element 220, so that the shielding piece 230 can more comprehensively shield the bottom edge of the cleaning element 220 when the shielding piece 230 is in the first position, thereby reducing or avoiding the possibility of the walking surface being polluted by the cleaning assembly 200 and improving the cleanliness of the walking surface.

[0073] As shown in Figure 2 In some possible implementation embodiments provided by the present application, the main body part 231 is located below the cleaning element 220 when the shielding piece 230 is in the first position, and the main body part 231 is located beside the cleaning element 220 when the shielding piece 230 is in the second position.

[0074] In some possible implementation examples, the cleaning element 220 is arranged at the bottom of the cleaning device, so as to facilitate contact with the walking surface. In the embodiment of the present application, when the shielding member 230 is in the first position, the main body 231 is located below the cleaning element 220, so that the main body 231 can shield the bottom edge of the cleaning element 220 along the length direction of the cleaning element 220, so as to separate the cleaning element 220 and the walking surface, thereby achieving good shielding effect. In this way, the garbage attached to the cleaning element 220 can fall on the shielding member 230 under the action of gravity, and the carpet hair can contact the shielding member 230 and not contact the cleaning element 220, thereby reducing the possibility of the walking surface being contaminated by the cleaning assembly 200 and improving the cleanliness of the walking surface.

[0075] As shown in Figure 3 , when the shielding member 230 is in the second position, the main body 231 is located at the side of the cleaning element 220, so that the main body 231 can expose the bottom edge of the cleaning element 220, so as to facilitate the cleaning operation by using the bottom edge of the cleaning element 220.

[0076] Further, the attachments falling on the shielding member 230 located below the cleaning element 220 when the shielding member 230 is in the first position can continue to be attached to the shielding member 230 when the shielding member 230 moves to the second position located at the side of the cleaning element 220, and / or fall on the walking surface, so as to facilitate subsequent cleaning by using the cleaning element 220.

[0077] As shown in Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , in some possible implementation examples provided by the present application, the cleaning element 220 is a cleaning roller, and the cross section of the main body 231 perpendicular to the length direction is arc-shaped.

[0078] Specifically, the cleaning roller is cylindrical, the self-axis line of the cleaning roller is parallel to the X+ and X- directions, the cleaning roller has small volume, which can meet the design requirement of compact structure of the cleaning assembly 200, and the cleaning roller has low cost, which is conducive to saving maintenance cost and replacement cost.

[0079] Specifically, the cleaning roller is cylindrical, the self-axis line of the cleaning roller is parallel to the X+ and X- directions, the cleaning roller has small volume, which can meet the design requirement of compact structure of the cleaning assembly 200, and the cleaning roller has low cost, which is conducive to saving maintenance cost and replacement cost. Figure 5 and Figure 6As shown in the figure, the main body part 231 is arc-shaped in the cross section perpendicular to the length direction, that is, the main body part 231 is arc-shaped as a whole, and the arc-shaped main body part 231 matches the partial shape of the cleaning roller to cover the partial circumferential side of the cleaning roller, so that the connecting part 232 rotates relative to the mounting frame 210, and the arc-shaped main body part 231 can cover different circumferential sides of the cleaning roller to realize the movement of the shielding piece 230 between the first position and the second position. This arrangement can make the distance between the main body part 231 and the cleaning roller smaller, realize the compact layout of the shielding piece 230 and the cleaning element 220, and further meet the design requirements of compact structure and small volume of the cleaning assembly 200.

[0080] As shown in the figure, Figure 4 the connecting part 232 is located on the side of the main body, and the connecting part 232 is fan-shaped, so that the connecting part 232 can provide stable and reliable support for the main body part 231.

[0081] As shown in the figure, Figure 4 in some possible implemented embodiments provided in the present application, the connecting part 232 is located on one side or both sides of the main body part 231. Since the connecting part 232 is rotationally connected with the mounting frame 210, by locating the connecting part 232 on one side of the main body, one side of the shielding piece 230 is rotationally connected with the mounting frame 210 through the connecting part 232; by locating the connecting part 232 on both sides of the main body, both sides of the shielding piece 230 are rotationally connected with the mounting frame 210 through the connecting part 232, so as to meet the requirements of different structures of the shielding piece 230 and different connection modes of the shielding piece 230 and the mounting frame 210.

[0082] As shown in the figure, Figure 4 one side of the shielding piece 230 is rotationally connected with the mounting frame 210 through the connecting part 232, which can simplify the structure of the shielding piece 230 and the assembly operation of the shielding piece 230 and the mounting frame 210, and is beneficial to improving the assembly efficiency and saving the manufacturing cost.

[0083] As shown in the figure,

[0084] Specifically, the connecting part 232 and the mounting frame 210 can be rotationally connected through a rotating shaft.

[0085] As shown in the figure, Figure 4 , Figure 5 and Figure 6As shown, in some possible implementation of the present application, the connecting portion 232 is located on one side of the main body, the portion of the main body portion 231 away from the connecting portion 232 is provided with a guide portion 233, the mounting rack 210 is provided with a guide channel 211, the shape of the guide channel 211 matches the movement track of the shielding piece 230, and the guide portion 233 extends into the guide channel 211 and can move along the guide channel 211.

[0086] The present embodiment discloses that one side of the shielding piece 230 is rotationally connected with the mounting rack 210 through the connecting portion 232. In the present embodiment, the guide portion 233 is arranged on the portion of the main body portion 231 away from the connecting portion 232, the mounting rack 210 is provided with the guide channel 211 matching the movement track of the main body portion 231, the guide portion 233 and the guide channel 211 are used for limiting and guiding, which can improve the rotation accuracy of the side of the main body portion 231 away from the connecting portion 232 relative to the mounting rack 210, reduce the possibility that the side of the main body portion 231 away from the connecting portion 232 interferes with the cleaning element 220 because of no support, and make the whole main body portion 231 rotate smoothly and flexibly relative to the mounting rack 210, so that the shielding piece 230 can move smoothly and flexibly between the first position and the second position.

[0087] As shown, Figure 6 In some possible implementation of the present application, the mounting rack 210 includes a rack body 212 and a guide rack 213, the guide rack 213 is connected to the outer circumferential side of the rack body 212, the guide channel 211 is formed between the guide rack 213 and the rack body 212, and the shielding piece 230 is located between the rack body 212 and the guide rack 213, so that the guide portion 233 on the main body portion 231 of the shielding piece 230 can be located in the guide channel 211 and move along the guide channel 211.

[0088] The cleaning element 220 and the shielding piece 230 are connected with the rack body 212, so that the rack body 212 can well support the cleaning element 220 and the shielding piece 230. The bottom end of the rack body 212 is provided with an avoiding opening 214 to expose the cleaning element 220, so that the bottom edge of the cleaning element 220 can be exposed outside the avoiding opening 214 to interfere with the walking surface to perform cleaning operation.

[0089] In some possible implementation of the present application, the shielding piece 230 and / or the mounting rack 210 is provided with a limiting structure 234, and the limiting structure 234 is configured to limit the movement of the shielding piece 230.

[0090] The arrangement of the limiting structure 234 can improve the accuracy of the operation of the shielding member 230 to the first position and / or the second position, reduce or avoid the possibility that the shielding member 230 does not fully shield the bottom edge of the cleaning element 220 when in the first position, so as to pollute the walking surface by the cleaning element 220, and improve the cleanliness of the walking surface. And / or, reduce or avoid the possibility that the shielding member 230 moves beyond the range relative to the cleaning element 220 and collides with the mounting frame 210 or other components, improve the reliability of the shielding member 230, the mounting frame 210 or other components, and improve the overall reliability of the cleaning assembly 200.

[0091] The limiting structure 234 can be arranged on the shielding member 230 to limit the movement of the shielding member 230 relative to the mounting frame 210 by cooperating with the limiting structure 234 and the mounting frame 210. Alternatively, the limiting structure 234 can be arranged on the mounting frame 210 to limit the movement of the shielding member 230 relative to the mounting frame 210 by cooperating with the limiting structure 234 and the shielding member 230. Alternatively, the limiting structure 234 can be arranged on both the shielding member 230 and the mounting frame 210 to limit the movement of the shielding member 230 relative to the mounting frame 210 by cooperating with the limiting structure 234 on the shielding member 230 and the limiting structure 234 on the mounting frame. Specifically, the limiting structure 234 can be a recess, a protrusion, a concave-convex structure, etc., and the limiting structures 234 on the shielding member 230 and the mounting frame 210 can be the same or different.

[0092] As shown in Figure 4 and Figure 6 In some possible implementation embodiments provided by the present application, the main body 231 is provided with the limiting structure 234, which is in contact with the frame body 212 at the avoiding opening 214 to limit the shielding member 230.

[0093] In this embodiment, the structure of the frame body 212 is reasonably utilized, so that the frame body 212 at the avoiding opening 214 is in contact with the limiting structure 234 on the main body 231 to limit the shielding member 230. This can avoid or reduce the possibility that the shielding member 230 continues to rotate in the reverse direction after reaching the second position during the movement of the shielding member 230 from the first position to the second position in the reverse direction, and collides with the mounting frame 210 or other components to be damaged, thereby improving the reliability of the shielding member 230, the mounting frame 210 or other components, and improving the overall reliability of the cleaning assembly 200. At the same time, this arrangement simplifies the arrangement of the limiting structure 234 on the frame body 212, which is conducive to saving manufacturing costs, and can make the layout of the mounting frame 210 and the shielding member 230 compact, thereby meeting the design requirements of compact structure and small size of the cleaning assembly 200.

[0094] As shown in Figure 6As shown, specifically, the limiting structure 234 includes a step structure arranged on the main body 231, and the step structure includes a first ladder portion 235 and a second ladder portion 236, wherein the first ladder portion 235 is located behind the second ladder portion 236 in the reverse direction, the distance between the first ladder portion 235 and the cleaning element 220 is smaller than the distance between the second ladder portion 236 and the cleaning element 220, the distance between the shelf body 212 at the avoiding opening 214 and the cleaning element 220 is greater than the distance between the first ladder portion 235 and the cleaning element 220, and the distance between the shelf body 212 at the avoiding opening 214 and the cleaning element 220 is smaller than the distance between the second ladder portion 236 and the cleaning element 220. Therefore, when the shielding piece 230 moves from the first position to the second position in the reverse direction, the second ladder portion 236 of the shielding piece 230 will first pass through the shelf body 212 at the avoiding opening 214 and can smoothly pass through the shelf body 212 at the avoiding opening 214, while the first ladder portion 235 will be in contact with the shelf body 212 at the avoiding opening 214, preventing the shielding piece 230 from continuing to move in the reverse direction. Thus, the possibility of the shielding piece 230 continuing to rotate in the reverse direction and colliding with the mounting shelf 210 or other components to cause damage can be reduced or avoided, the reliability of the shielding piece 230, the mounting shelf 210, or other components can be improved, and the overall reliability of the cleaning assembly 200 can be improved.

[0095] It can be understood that in other examples, the limiting structure 234 can also be other structures, such as a protruding rib, a boss, etc.

[0096] As shown, Figure 7 In some possible implemented embodiments provided by the present application, the cleaning assembly 200 further includes a first driving portion 240 and a first transmission portion 250, the first driving portion 240 and the first transmission portion 250 are installed on the mounting shelf 210, the first driving portion 240 is in power connection with the first transmission portion 250, the first transmission portion 250 is connected with the connecting portion 232, and the first driving portion 240 drives the shielding piece 230 to rotate through the first transmission portion 250.

[0097] In the present embodiment, the first driving portion 240 drives the shielding piece 230 to rotate through the first transmission portion 250, the first transmission portion 250 can adjust the output force of the first driving portion 240, and further adjust the rotation speed of the shielding piece 230, so that the shielding piece 230 can smoothly, accurately and flexibly move between the first position and the second position.

[0098] The driving mode of the first driving portion 240 can be at least one of electric driving, hydraulic driving, and pneumatic driving. The first transmission portion 250 can be at least one of a gear mechanism, a gear and rack mechanism, a chain transmission, and a belt transmission.

[0099] As shown, Figure 7As shown, in some possible embodiments provided in this application, the first transmission unit 250 includes a gear set that meshes with each other. The gear set includes a first gear 251 and a second gear. The first gear 251 is poweredly connected to the first drive unit 240, and the second gear is connected to the shield 230. Alternatively, the second gear is configured as a tooth 237 formed on the shield 230.

[0100] This embodiment provides an example where the first transmission part 250 is a gear mechanism. The first transmission part 250 includes a set of meshing gears, which includes a first gear 251 and a second gear. The first gear 251 is poweredly connected to the first drive part 240. For example, the first drive part 240 can be a motor, and the first gear 251 is connected to the output shaft of the motor.

[0101] The second gear can be connected to the shield 230, thereby enabling the first drive unit 240 to operate and drive the shield 230 to rotate via the first gear 251 and the second gear of the gear set. This transmission method has a simple structure, high motion accuracy, and small size, which can meet the design requirements of the cleaning component 200 for a compact structure and small size.

[0102] Among them, such as Figure 4 and Figure 7 As shown, the second gear is configured as a tooth 237 formed on the shield 230, meaning the tooth 237 of the shield 230 meshes with the first gear 251. Thus, the first drive unit 240 operates, driving the shield 230 to rotate via the first gear 251 and the tooth 237 formed on the shield 230. This transmission method is simple in structure, has high motion accuracy, and integrates the second gear and the shield 230 into a single structure, simplifying the separate second gear configuration. This further reduces the size of the first transmission unit 250 and the cleaning assembly 200, meeting the design requirements of a compact and small-sized cleaning assembly 200. Simultaneously, this configuration reduces the manufacturing cost of the first transmission unit 250, making it suitable for widespread application.

[0103] like Figure 7 As shown, in some possible embodiments provided in this application, the gear set further includes at least one transition gear 252 located between the first gear 251 and the second gear. Thus, the power of the first drive unit 240 is transmitted to the blocking member 230 through the first gear 251, at least one transition gear 252, and the second gear, thereby driving the blocking member 230 to rotate. The arrangement of the first gear 251, the second gear, and at least one transition gear 252 can achieve speed regulation, enabling the blocking member 230 to operate smoothly at a suitable speed, thereby improving the smoothness and accuracy of the movement of the blocking member 230 between the first and second positions. Specifically, the number of transition gears 252 can be one, two, three, or more.

[0104] As shown in Figure 2 and Figure 3 In some possible implementation of the present application, the cleaning assembly 200 further comprises a mounting plate 260, the mounting plate 260 is connected with the mounting frame 210, and the first driving part 240 is connected to the mounting plate 260. Thus, the mounting plate 260 connected to the mounting frame 210 can provide support force for the first driving part 240, so that the first driving part 240 can be reliably and stably fixed relative to the mounting frame 210.

[0105] The first driving part 250 and the at least partial connecting part 232 are located in the mounting space formed between the mounting plate 260 and the mounting frame 210, so that the mounting plate 260 and the mounting frame 210 can well protect the first driving part 250 and the at least partial connecting part 232, and help to improve the reliability of the first driving part 250 and the connecting part 232 and the overall reliability of the cleaning assembly 200.

[0106] Specifically, the mounting plate 260 is detachably connected with the mounting frame 210, so as to facilitate disassembly and assembly of the first driving part 250 and the shielding piece 230 and facilitate maintenance. Specifically, the mounting plate 260 and the mounting frame 210 can be detachably connected through at least one of a bolt structure, a clamping structure, a magnetic attraction structure, and a mortise and tenon structure.

[0107] In some possible implementation of the present application, the cleaning assembly 200 further comprises a first driving part 240, the first driving part 240 is power-connected with the shielding piece 230 to drive the shielding piece 230 to rotate. Thus, the first driving part 240 works to directly transmit power to the shielding piece 230 to drive the shielding piece 230 to rotate. This transmission mode directly drives the shielding piece 230 to rotate by the first driving part 240, simplifies the setting of the first driving part, helps to save costs, and can meet the design requirements of compact structure and small size of the cleaning assembly 200.

[0108] In some possible implementation of the present application, the cleaning assembly 200 further comprises a linkage assembly, the cleaning assembly 200 is used for a cleaning module 300 of a cleaning device, the cleaning device comprises a machine body, the cleaning module 300 comprises a lifting device 100 connecting the machine body and the cleaning assembly 200, the lifting device 100 is configured to drive the cleaning assembly 200 to switch between an ascending position and a descending position relative to the machine body, and the linkage assembly is power-connected with the lifting device 100 to drive the shielding piece 230 to rotate through the linkage assembly. This transmission mode drives the shielding piece 230 to rotate through the linkage assembly by the work of the lifting device 100, simplifies the setting of the first driving part, helps to save costs, and can meet the design requirements of compact structure and small size of the cleaning assembly 200.

[0109] The linkage assembly can be a lifting mechanism, a connecting rod mechanism, or the like. For example, the linkage assembly can be a lifting structure composed of a pull rope and a pulley, or the linkage assembly can be a four-bar linkage mechanism. It can be understood that the linkage assembly can also be other structures, which are not listed here.

[0110] The lifting device 100 drives the cleaning assembly 200 to the raised position, and the linkage assembly drives the shielding piece 230 to rotate to the first position. Since the cleaning assembly 200 in the raised position is at a certain distance from the walking surface, the cleaning element 220 does not interfere with the walking surface. Therefore, the lifting device 100 drives the cleaning assembly 200 to the raised position, and the linkage assembly drives the shielding piece 230 to rotate to the first position to shield the bottom edge of the cleaning element 220, which can reduce the possibility of the walking surface being contaminated by the cleaning element 220, improve the cleanliness of the walking surface, and improve the overall cleaning effect of the cleaning equipment.

[0111] The lifting device 100 drives the cleaning assembly 200 to the lowered position, and the linkage assembly drives the shielding piece 230 to the second position. Since the lowered position can be understood as the working position of the cleaning element 220, that is, the cleaning element 220 needs to contact the walking surface for cleaning operation, the lifting device 100 drives the cleaning assembly 200 to the lowered position, and the linkage assembly drives the shielding piece 230 to rotate to the second position to expose the bottom edge of the cleaning element 220, so that the bottom edge of the cleaning element 220 can smoothly contact the walking surface for cleaning operation.

[0112] In some possible implementation embodiments provided in the present application, the cleaning assembly 200 further includes a detection assembly configured to detect whether the shielding piece 230 is in the first position and / or the second position.

[0113] In the present embodiment, the detection assembly is provided to accurately detect the position of the shielding piece 230, and then the working state of the first driving part 240 can be controlled according to the detection result of the detection assembly, so that the shielding piece 230 can accurately and smoothly operate to the first position and / or the second position to better achieve the shielding and exposure effects.

[0114] The detection assembly can detect whether the shielding piece 230 is in the first position, or the detection assembly can detect whether the shielding piece 230 is in the second position, or the detection assembly can detect whether the shielding piece 230 is in the first position and the second position.

[0115] The detection assembly can be a position switch, such as a microswitch, a limit switch, a photoelectric switch, or the like, to achieve limit detection.

[0116] The detection assembly can also be detected by the odometer of the first driving part 240. For example, the first driving part 240 is a motor, and the odometer of the motor can be used to detect the position. The odometer is used to record and display the total distance traveled by the first driving part 240 since it is manufactured or last reset. Thus, the rotation angle of the shielding part 230 since the last reset (for example, the first position or the second position) can be analyzed, and the position detection can be realized.

[0117] As shown in Figure 1 The embodiment of the second aspect of the application provides a cleaning module 300, which comprises the cleaning assembly 200 of any one of the embodiments of the first aspect. Since the cleaning module 300 comprises the cleaning assembly 200 of any one of the preceding embodiments, it has all the technical effects of the cleaning assembly 200, which will not be repeated here.

[0118] As shown in Figure 1 In some possible implementation examples, the cleaning module 300 further comprises a lifting device 100, the cleaning assembly 200 is connected with the lifting device 100, the cleaning module 300 is used for cleaning equipment, the lifting device 100 is connected with a machine body of the cleaning equipment, and the lifting device 100 is configured to drive the cleaning assembly 200 to switch between the raised position and the lowered position relative to the machine body. Thus, the needs of different operations of the cleaning assembly 200 can be met. For example, when the cleaning assembly 200 needs to work, for example, the walking surface is an area that needs to be mopped, washed, or waxed, the lifting device 100 drives the cleaning assembly 200 to be in the lowered position, so that the cleaning assembly 200 can interfere with the walking surface to perform cleaning operation. When the cleaning assembly 200 does not need to work, for example, the walking surface is an area that does not need to be mopped, washed, or waxed, for example, the walking surface is a carpet area, the lifting device 100 drives the cleaning assembly 200 to be in the raised position, so that the cleaning assembly 200 has a certain distance from the walking surface, and the cleaning assembly 200 does not interfere with the walking surface and does not perform cleaning operation on the walking surface.

[0119] It can be understood that the lifting device 100 can realize the lifting and lowering of the cleaning assembly 200. In some examples, the lifting device 100 comprises a transmission device, and the lifting and lowering of the cleaning assembly 200 is realized by the transmission device. The transmission device can include but is not limited to the following schemes.

[0120] In some possible implementation examples provided by the application, the lifting device 100 is further configured to drive the cleaning assembly 200 to switch between the first working position and the second working position relative to the machine body. Thus, the cleaning assembly 200 can be moved to the working position that meets the requirements of the corresponding cleaning range, so as to meet the requirements of different cleaning ranges, expand the cleaning range, and improve the cleaning effect and the user's cleaning experience.

[0121] The cleaning assembly 200 in the first working position and the second working position is located at different positions of the machine body in the horizontal direction, which can be understood as parallel to the X+ and X- directions. Specifically, at least part of the cleaning assembly 200 in the first working position is located inside the machine body in the horizontal direction, at least part of the cleaning assembly 200 in the second working position is located outside the machine body in the horizontal direction, and the area outside the machine body of the cleaning assembly 200 in the second working position is larger than that of the cleaning assembly 200 in the first working position. Thus, the cleaning assembly 200 in the second working position can be in contact with more walking surfaces outside the machine body, thereby increasing the cleaning range of the cleaning assembly 200. For example, the cleaning assembly 200 can handle garbage in the corner, reduce dead angle positions in the walking surface that cannot be cleaned by the cleaning device, reduce the possibility that the cleaning range of the cleaning assembly 200 is limited by the shape of the machine body, and achieve cleaning work in the corner area. Specifically, the first working position can be understood as the cleaning assembly 200 being in a retracted state relative to the machine body, and the second working position can be understood as the cleaning assembly 200 being in an extended state relative to the machine body.

[0122] In the embodiment, the lifting device 100 can realize the lifting movement of the cleaning assembly 200 between the raised position and the lowered position, and can also realize the translation movement of the cleaning assembly 200 between the first working position and the second working position. Thus, compared with the related art in which the lifting movement and the translation movement of the cleaning assembly 200 are realized by two mechanisms respectively, the structure is simplified, the cost is saved, and the design requirement of compact structure and small volume of the lifting device 100 can be met.

[0123] As shown in Figure 8 , Figure 9 and Figure 10 , in some possible implemented embodiments provided in the present application, the lifting device 100 includes a mounting seat 110, a translation piece 120, and a connecting piece 130. The translation piece 120 is movably arranged on the mounting seat 110, and the translation piece 120 is connected with the cleaning assembly 200 through the connecting piece 130. The translation piece 120 is configured to move relative to the mounting seat to drive the cleaning assembly 200 to move between the first working position and the second working position, and between the raised position and the lowered position.

[0124] In this embodiment, the mounting base 110 of the lifting device 100 is connected with the machine body, the translation piece 120 of the lifting device 100 is movably arranged on the mounting base 110, the translation piece 120 is connected with the cleaning assembly 200 through the connecting piece 130, and the translation piece 120 moves relative to the mounting base 110 to drive the cleaning assembly 200 to move between the first working position and the second working position. Thus, the cleaning assembly 200 can be moved to a working position meeting the requirement of a corresponding cleaning range, so as to meet the requirement of different cleaning ranges, expand the cleaning range, and improve the cleaning effect and the user's cleaning experience. The translation piece 120 moves relative to the mounting base 110 to drive the cleaning assembly 200 to move between the raised position and the lowered position, so as to meet the requirement of the cleaning assembly 200 needing to perform a cleaning operation or not needing to perform a cleaning operation. Specifically, the cleaning assembly 200 includes a connecting arm 201, and the cleaning assembly 200 is connected with the connecting piece 130 through the connecting arm 201. Specifically, the translation piece 120 can be slidably arranged on the mounting base 110, or the translation piece 120 can be rollingly arranged on the mounting base 110.

[0125] As shown in Figure 8 and Figure 9 , in some embodiments, one end of the elastic piece 140 is connected with the connecting piece 130, and the other end is connected with the translation piece 120. It can be understood that the connecting piece 130 and the translation piece 120 are connected through the elastic piece 140. In this case, the mounting base 110 and the machine body can be understood as fixedly connected, that is, the relative position of the mounting base 110 and the machine body is fixed after being connected. Specifically, the mounting base 110 can be directly connected with the machine body or indirectly connected with the machine body through other components. During the movement of the cleaning assembly 200 from the first working position to the second working position along the first direction, an external force is transmitted to the connecting piece 130 to deform the elastic piece 140, the direction of the external force is the second direction, so that the cleaning assembly 200 moves in the second direction, and the second direction is opposite to the first direction. Wherein, the first direction is indicated by the arrow X+ in Figures 1 to 3 , Figures 8 to 13 , and the second direction is indicated by the arrow X- in Figures 1 to 3 , Figures 8 to 13 .

[0126] That is, when the cleaning assembly 200 collides with the obstacle during the movement and extension from the first working position to the second working position in the first direction and is subjected to the external force in the second direction, the deformation of the elastic member 140 can play a good buffering role, for example, the deformation of the elastic member 140 can drive the cleaning assembly 200 to move passively in the second direction through the connecting member 130, thereby reducing the influence of the obstacle on the cleaning assembly 200, the connecting member 130, the translation member 120, and the transmission part 150 and the driving part mentioned below, and improving the reliability of the cleaning assembly 200 and the lifting device 100. At the same time, the possibility of displacement of the cleaning equipment due to the force on the cleaning assembly 200 can be reduced, the operation accuracy of the cleaning equipment can be improved, and a good cleaning effect can be improved. In this way, the elastic member 140 can be arranged inside the mounting seat 110, which is conducive to improving the neatness and aesthetics of the appearance of the lifting device 100 and improving the service life of the elastic member 140.

[0127] As shown in Figure 10 In some embodiments, one end of the elastic member 140 is connected to the mounting seat 110, and the other end is connected to the machine body of the cleaning equipment. It can be understood that the mounting seat 110 and the machine body are connected through the elastic member 140. In this case, the relative position of the connecting member 130 and the translation member 120 after being connected is fixed. Specifically, the connecting member 130 can be directly connected to the translation member 120 or indirectly connected to the translation member 120 through other components. During the movement of the cleaning assembly 200 from the first working position to the second working position in the first direction, the external force is transmitted to the mounting seat 110 to deform the elastic member 140, so that the cleaning assembly 200 moves in the second direction, and the second direction is opposite to the first direction. The direction of the external force is the second direction.

[0128] That is, when the cleaning assembly 200 collides with the obstacle during the movement and extension from the first working position to the second working position in the first direction and is subjected to the external force in the second direction, the deformation of the elastic member 140 can play a good buffering role, for example, the deformation of the elastic member 140 can drive the cleaning assembly 200 to move passively in the second direction through the connecting member 130, thereby reducing the influence of the obstacle on the cleaning assembly 200, the connecting member 130, the translation member 120, and the transmission part 150 and the driving part mentioned below, and improving the reliability of the cleaning assembly 200 and the lifting device 100. At the same time, the possibility of displacement of the cleaning equipment due to the force on the cleaning assembly 200 can be reduced, the operation accuracy of the cleaning equipment can be improved, and a good cleaning effect can be improved. In this way, the elastic member 140 can be arranged inside the mounting seat 110, which is conducive to improving the neatness and aesthetics of the appearance of the lifting device 100 and improving the service life of the elastic member 140.

[0129] To this end, the embodiments provided in the present application connect different components through the elastic member 140, such as connecting the connecting piece 130 and the translation main body of the lifting device 100, or connecting the mounting seat 110 and the machine main body of the cleaning equipment, so that when the cleaning assembly 200 collides with an obstacle during the movement and extension process from the first working position to the second working position in the first direction and is subjected to an external force in the second direction, the elastic member 140 deforms to play a good buffering effect, drives the cleaning assembly 200 to move in the second direction, reduces the reliability of the cleaning assembly 200 and the lifting device 100 failure and damage, improves the reliability of the cleaning assembly 200 and the lifting device 100, and at the same time, reduces the possibility of displacement of the cleaning equipment due to the force on the cleaning assembly 200, improves the operation accuracy of the cleaning equipment. And the different setting positions of the elastic member 140 can meet the needs of various structures of the lifting device 100, and have a wide range of applications.

[0130] In some possible implementation embodiments provided in the present application, the cleaning assembly 200 is subjected to an external force transmitted to the connecting piece 130 or the mounting seat 110 to deform the elastic member 140 during the movement from the second working position to the first working position in the second direction, so as to move the cleaning assembly 200 in the first direction. Wherein, the direction of the external force is the second direction.

[0131] In the present embodiment, when the cleaning assembly 200 is subjected to an external force in the second direction during the movement and retraction process from the second working position to the first working position in the second direction, the elastic member 140 deforms to play a good buffering effect, such as the elastic member 140 deforming to drive the connecting piece 130 or the lifting device 100 to accelerate movement in the second direction, and then the cleaning assembly 200 is passively retracted in the second direction to accelerate movement, that is, when subjected to an external force in the second direction, the retraction speed of the cleaning assembly 200 is greater than the retraction speed of the cleaning assembly 200 driven by the translation piece 120. Thus, the influence of the external force on the cleaning assembly 200, the connecting piece 130, the translation piece 120, and the driving part and the transmission part 150 mentioned later can be reduced, which is beneficial to improve the reliability of the cleaning assembly 200 and the lifting device 100, and at the same time, the possibility of displacement of the cleaning equipment due to the force on the cleaning assembly 200 can be reduced, the operation accuracy of the cleaning equipment is improved, and good cleaning effect is ensured.

[0132] In some possible implementation embodiments provided in the present application, the cleaning assembly 200 is subjected to an external force transmitted to the connecting piece 130 or the mounting seat 110 to deform the elastic member 140, so as to move the cleaning assembly 200 in the second direction, wherein the direction of the external force is the second direction.

[0133] In the second working position of the cleaning assembly 200 in the extended state, the cleaning assembly 200 collides with the obstacle under the action of the external force in the second direction, and the elastic member 140 deforms to play a good buffering effect. For example, the elastic member 140 deforms to drive the connecting member 130 or the lifting device 100 to move in the second direction, and then the cleaning assembly 200 is passively extended and retracted in the second direction, so as to reduce the influence of the obstacle on the cleaning assembly 200, the connecting member 130, the translation member 120, and the transmission part 150 and the driving part mentioned later. This is beneficial to improve the reliability of the cleaning assembly 200 and the lifting device 100, and at the same time, it can reduce the possibility of displacement of the cleaning equipment due to the force on the cleaning assembly 200, and improve the operation accuracy of the cleaning equipment.

[0134] Therefore, the lifting device 100 provided by the present application is provided with the elastic member 140, which is connected to the connecting member 130 and the translation member 120, or is connected to the mounting seat 110 and the machine body. In this way, when the cleaning assembly 200 moves from the first working position to the second working position, moves from the second working position to the first working position, or is in the second working position, and is subjected to an external force in the second direction, the elastic member 140 can deform to buffer the external force on the cleaning assembly 200, thereby improving the reliability of the cleaning assembly 200 and the lifting device 100, improving the operation accuracy of the cleaning equipment, and improving the overall reliability of the equipment.

[0135] As shown in Figure 8 In some possible implementation examples provided by the present application, the elastic member 140 is connected to the connecting member 130 and the translation member 120, and the elastic member 140 is configured to keep the connecting member 130 and the translation member 120 in the first relative static position. It can be understood that the connecting member 130 and the translation member 120 can move as a whole when they keep the first relative static position. Therefore, the movement of the translation member 120 relative to the mounting seat 110 can drive the connecting member 130 to move relative to the mounting seat 110, so that the cleaning assembly 200 moves between the first working position and the second working position, thereby meeting the needs of different cleaning ranges and expanding the cleaning range of the cleaning assembly 200. This kind of transmission structure is simple in structure and convenient in transmission, and the elastic member 140 is low in cost and small in size, which can meet the design requirements of low cost and compact structure of the lifting device 100.

[0136] It can be understood that at least the elastic member 140 is configured to keep the connecting member 130 and the translation member 120 in the first relative static position. It can be understood that the elastic member 140 can keep the connecting member 130 and the translation member 120 in the first relative static position under the action of the elastic member 140, or the elastic member 140 and other structures can jointly keep the connecting member 130 and the translation member 120 in the first relative static position.

[0137] like Figure 9 As shown, in some possible embodiments provided in this application, the connector 130 is configured to move from a first relatively stationary position along a second direction under the action of an external force, thereby driving the cleaning component 200 to move in the second direction.

[0138] In this embodiment, when the cleaning component 200 is moved from the first working position to the second working position along the first direction and is subjected to an external force transmitted to the connector 130, the connector 130 is subjected to an external force and moves from the first relatively stationary position along the second direction. This process can cause the elastic element 140 to deform to accumulate elastic potential energy, thereby driving the cleaning component 200 to move in the second direction, reducing the impact of external force on the cleaning component 200 and the lifting device 100. At the same time, it can reduce the possibility of the cleaning equipment shifting due to the force on the cleaning component 200, and improve the reliability and operating accuracy of the cleaning equipment.

[0139] In the above embodiment, the elastic element 140 releases elastic potential energy to drive the connector 130 to move along the first direction.

[0140] As the cleaning component 200 moves from the first working position to the second working position along the first direction, the elastic element 140 deforms due to external force, accumulating elastic potential energy. The elastic element 140 releases this elastic potential energy to drive the connecting member 130 to move along the first direction. When the external force is removed, the elastic element 140 releases its elastic potential energy to drive the connecting member 130 to move along the first direction, thus allowing the connecting member 130 to return to its first relatively stationary position under the action of the elastic element 140. Furthermore, during the release of its elastic potential energy, the elastic element 140 can push away or bounce away obstacles located in front of the cleaning component 200 along the first direction, achieving obstacle cleaning and improving the cleaning effect of the cleaning component 200. Specifically, by reasonably setting the initial length, elastic force, and deformation relationship of the elastic element 140, the elastic element 140 can, at its initial length, keep the connecting member 130 and the translation member 120 in the first relatively stationary position. Alternatively, by cooperating with other structures (such as the limiting part 160 mentioned later), the elastic element 140 is obstructed by the limiting part 160 after releasing its elastic potential energy, so that the connecting member 130 and the translation member 120 are in a first relatively stationary position.

[0141] like Figure 10As shown, in some possible implemented embodiments provided in the present application, the elastic member 140 connects the mounting seat 110 and the machine body, and is configured to keep the mounting seat 110 and the machine body in the second relatively static position. In this case, the mounting seat 110 and the machine body kept in the second relatively static position can be understood as that the mounting seat 110 and the machine body can move as a whole. Therefore, the movement of the translation member 120 relative to the mounting seat 110 can drive the connection member 130 to move relative to the mounting seat 110, so as to drive the cleaning assembly 200 to move between the first working position and the second working position, thereby expanding the cleaning range of the cleaning assembly 200. Such transmission arrangement is simple in structure and convenient in transmission, and the elastic member 140 is low in cost and small in size, which can meet the design requirements of the lifting device 100 in low cost and compact structure. In this case, the initial length, the elastic force and the deformation amount of the elastic member 140 can be reasonably set, so that the elastic member 140 can keep the connection member 130 and the translation member 120 in the first relatively static position at the initial length. Alternatively, the elastic member 140 can be combined with other structures to be hindered by other structures after releasing the elastic potential energy, so as to keep the mounting seat 110 and the machine body in the second relatively static position.

[0142] It can be understood that at least the elastic member 140 is configured to keep the mounting seat 110 and the machine body in the second relatively static position, which can be understood as that the mounting seat 110 and the machine body can be kept in the second relatively static position under the action of the elastic member 140, or the mounting seat 110 and the machine body can be kept in the second relatively static position under the cooperation of the elastic member 140 and other structures.

[0143] In the above embodiment, the mounting seat 110 is configured to move along the second direction from the second relatively static position under the action of the external force, thereby driving the lifting device 100 to move in the second direction.

[0144] In the present embodiment, when the cleaning assembly 200 is subjected to the external force transmitted to the mounting seat 110 during the movement of the cleaning assembly 200 along the first direction from the first working position to the second working position, the mounting seat 110 is subjected to the external force and moves along the second direction from the second relatively static position. This process can make the elastic member 140 deform to accumulate the elastic potential energy, thereby driving the translation member 120, the connection member 130 and the cleaning assembly 200 to move in the second direction synchronously, reducing the influence of the external force on the cleaning assembly 200 and the lifting device 100, and reducing the possibility of displacement of the cleaning equipment due to the force on the cleaning assembly 200, thereby improving the reliability and operation accuracy of the cleaning equipment.

[0145] In the above embodiment, the elastic member 140 releases the elastic potential energy to drive the mounting seat 110 to move along the first direction.

[0146] As the cleaning assembly 200 is subjected to the external force during the movement from the first working position to the second working position along the first direction, the elastic member 140 is deformed to accumulate elastic potential energy, and the elastic member 140 releases the elastic potential energy to drive the mounting base 110 to move along the first direction, such that the mounting base 110 is capable of returning to the second relatively static position under the action of the elastic member 140. In addition, the elastic member 140 can push away or bounce off the obstacle near the front of the mounting base 110 or the cleaning assembly 200 along the first direction during the release of the elastic potential energy, so as to realize the cleaning operation on the obstacle and improve the cleaning effect of the cleaning assembly 200.

[0147] As shown in Figure 8 , Figure 9 and Figure 10 , in some possible implementation embodiments provided in the present application, the lifting device 100 further comprises a second driving part and a second transmission part 150, the second driving part is mounted on the mounting base 110, and the second transmission part 150 comprises a driving gear 151 and a rack 152 engaged with each other, the driving gear 151 is in power connection with the second driving part, and the rack 152 is connected with the translation member 120 and is driven by the driving gear 151 and the rack 152 to drive the translation member 120 to move relative to the mounting base 110, and then drive the cleaning assembly 200 to move between the first working position and the second working position. This kind of arrangement has the advantages of simple structure, high movement precision, small size, and can meet the design requirements of compact structure and small size of the lifting device 100.

[0148] The rack 152 and the translation member 120 can be a split structure, for example, the rack 152 is mounted on the translation member 120. This kind of arrangement facilitates the replacement and maintenance of the rack 152, and is beneficial to saving maintenance costs. Alternatively, the rack 152 and the translation member 120 are an integral structure, i.e., the translation member 120 comprises the rack 152. This kind of arrangement makes the rack 152 part of the structure of the translation member 120, simplifies the assembly operation of the translation member 120 and the rack 152, and is beneficial to improving the assembly efficiency of the lifting device 100 and saving manufacturing costs. It can be understood that, in other examples, the second transmission part 150 can also be a belt transmission, chain transmission or other transmission mode, which is not limited in the present application.

[0149] As shown in Figure 8 , Figure 9 , Figure 10 and Figure 11As shown, in some possible implementation embodiments provided in the present application, the translation member 120 is provided with a frame structure 121 at the end of the rack 152, the frame structure 121 is provided with a guide rail 122, the connecting member 130 is movably connected with the guide rail 122, and the translation movement of the translation member 120 guides the lifting of the cleaning assembly 200 through the guide rail 122 and the connecting member 130. When the cleaning assembly 200 is in the first working position and the second working position, the cleaning assembly 200 is in the lowered state. The cleaning assembly 200 further includes an initial position in the first working position and the raised state, and the initial position is the raised position. The first working position can be understood as the lowered position.

[0150] In the embodiment, by providing the frame structure 121 with the guide rail 122 on the translation member 120, the connecting member 130 is movably connected with the guide rail 122, and the translation movement of the translation member 120 relative to the mounting base 110 guides the lifting of the cleaning assembly 200 through the guide rail 122 and the connecting member 130. Thus, the translation movement of the cleaning assembly 200 between the first working position and the second working position can be realized by the second driving part driving the translation movement of the translation member 120 through the second transmission part 150, and the lifting movement of the cleaning assembly 200 can also be realized. Thus, compared with the related art in which the translation movement and the lifting movement of the cleaning assembly 200 are realized by two mechanisms respectively, the structure is simplified, the cost is saved, and the design requirement of compact structure and small volume of the lifting device 100 can be met. Specifically, the connecting member 130 can be slidably connected with the guide rail 122, or the connecting member 130 can be rollingly connected with the guide rail 122.

[0151] In the embodiment, the cleaning assembly 200 is in the raised position, that is, the cleaning assembly 200 is in the initial position, which can be understood as the cleaning assembly 200 being in the non-working position. At this time, the cleaning assembly 200 is in the raised state relative to the machine body to have a certain distance from the walking surface, and the cleaning assembly 200 is in the first working position to be accommodated in the interior of the machine body. When the cleaning assembly 200 is in the first working position, the cleaning assembly 200 can be understood as being retracted relative to the machine body, the cleaning assembly 200 is located in the area covered by the machine body, and the cleaning assembly 200 is in the lowered state, so that the cleaning assembly 200 can interfere with the walking surface and can perform the cleaning operation on the area covered by the machine body. When the cleaning assembly 200 is in the second working position, the cleaning assembly 200 can be understood as being extended relative to the machine body, part of the cleaning assembly 200 is located outside the area covered by the machine body, and the cleaning assembly 200 is in the lowered state, so that the cleaning assembly 200 can interfere with the walking surface and can perform the cleaning operation outside the area covered by the machine body to expand the cleaning range.

[0152] In some possible implementation embodiments provided in the present application, when the cleaning assembly 200 moves with the translation member 120 from the second working position to the first working position, the movement of the cleaning assembly 200 or the connecting member 130 in the second direction is limited, and the translation member 120 continues to move in translation, so that the connecting member 130 generates movement in the vertical direction from the bottom of the guide rail 122 to the top of the guide rail 122, and the fixed connection between the connecting member 130 and the cleaning assembly 200 causes the cleaning assembly 200 to rise from the first working position to the initial position.

[0153] That is, when the cleaning assembly 200 moves to the first working position, the movement of the cleaning assembly 200 or the connecting member 130 in the second direction is limited, for example, the cleaning assembly 200 abuts against the machine body to hinder the cleaning assembly 200 from continuing to move in the second direction, so that the connecting member 130 does not continue to move in the second direction, or the connecting member 130 abuts against the mounting seat 110 to hinder the connecting member 130 from continuing to move in the second direction. In this state, the translation member 120 continues to move in the second direction, and because the guide rail 122 is in moving contact with the connecting member 130, the cleaning assembly 200 can be guided by the guide rail 122 to rise to the initial position in the first working position, so as to realize the rising operation of the cleaning assembly 200. Specifically, the guide rail 122 is arranged obliquely to guide the cleaning assembly 200 to perform the lifting operation.

[0154] When the cleaning assembly 200 is in the initial position, the guide rail 122 is in moving contact with the connecting member 130, and because of the self-gravity of the cleaning assembly 200, the component force of the connecting member 130 in the vertical direction is greater than the component force of the connecting member 130 parallel to the oblique direction of the guide rail 122. In this case, when the translation member 120 moves in the first direction, the connecting member 130 does not move in translation with the translation member 120 under the action of the greater component force in the vertical direction, but is guided by the guide rail 122 to generate movement in the vertical direction from the top of the guide rail 122 to the bottom of the guide rail 122, thereby driving the cleaning assembly 200 to descend from the initial position to the first working position, so as to realize the descending operation of the cleaning assembly 200. When the cleaning assembly 200 is in the first working position, the connecting member 130 is located at the bottom of the guide rail 122, and it can also be understood that the connecting member 130 is separated from the guide rail 122. At this time, under the action of the self-gravity of the cleaning assembly 200, the connecting member 130 is relatively stationary with the translation member 120, and the translation member 120 continues to move in the first direction, driving the connecting member 130 to move synchronously, and further driving the cleaning assembly 200 to move to the second working position, so as to realize the movement of the cleaning assembly 200 from the first working position to the second working position. By means of the translation movement of the translation member 120 and the cooperation with the guide rail 122, the lifting operation and the translation operation of the cleaning assembly 200 can be realized, and the structure is simple and small in size.

[0155] AsFigure 11 As shown, in some possible embodiments provided in this application, the guide rail 122 is inclined upward along the first direction. Therefore, when the cleaning component 200 moves to the first working position, the movement of the cleaning component 200 or the connecting member 130 along the second direction is restricted, causing the translation member 120 to continue moving in the second direction. The guide rail 122, inclined upward along the first direction, cooperates with the connecting member 130 to guide the cleaning component 200 to rise. After the cleaning component 200 rises to the initial position, the translation member 120 moves along the first direction, and the guide rail 122, inclined upward along the first direction, cooperates with the connecting member 130 to guide the cleaning component 200 to descend. Thus, by reasonably setting the inclination direction of the guide rail 122 and cooperating with the translation member 120, the cleaning component 200 can be guided to rise and fall.

[0156] In some embodiments, the number of guide rails 122 is equal to the number of connectors 130, thereby ensuring that the connectors 130 can smoothly cooperate with the guide rails 122 to achieve the lifting and lowering operation of the cleaning assembly 200. Specifically, the number of connectors 130 and guide rails 122 can be one, two, three, or other numbers, etc. Figure 8 , Figure 9 , Figure 11 As shown, there are two connectors 130 and two guide rails 122.

[0157] like Figures 8 to 10 As shown, in some embodiments, the connector 130 is provided with rollers 170 for contacting the guide rail 122. The connector 130 contacts the guide rail 122 through the rollers 170. The rollers 170 improve the smoothness and flexibility of the relative movement between the connector 130 and the guide rail 122, reduce the possibility of jamming during the relative movement of the connector 130 and the guide rail 122, and thus improve the smoothness and flexibility of the lifting operation of the cleaning assembly 200. Specifically, the number of rollers 170 can be one, two, or more, and the number of rollers 170 can be reasonably set according to factors such as the size of the rollers 170, the size of the guide rail 122, and the number of guide rails 122.

[0158] like Figure 8 and Figure 9 As shown, in some possible embodiments provided in this application, the translation member 120 and / or the connecting member 130 are provided with a limiting part 160, and the elastic member 140 and the limiting part 160 cooperate to keep the translation member 120 and the connecting member 130 in a first relatively stationary position.

[0159] In this embodiment, by utilizing the limiting portion 160 provided on the translation member 120 and / or the connecting member 130 in cooperation with the elastic member 140, the translation member 120 and the connecting member 130 can be stably maintained in the first relatively stationary position. Thus, the translation member 120 and the connecting member 130 can move as a whole, so that the translation member 120 translates and the cleaning component 200 is driven to translate through the synchronously moving connecting member 130, so as to realize the switching of the cleaning component 200 between the first working position and the second working position.

[0160] The limiting part 160 can be provided on the translation member 120, or on the connecting member 130, or simultaneously on both the translation member 120 and the connecting member 130. It is understood that the first relative static position of the translation member 120 and the connecting member 130 can be disrupted when the cleaning assembly 200 is subjected to external force. In this case, the deformation of the elastic member 140 can provide good buffering protection for the lifting device 100 and the cleaning assembly 200.

[0161] In the above embodiment, the elastic member 140 and the limiting part 160 cooperate to prevent the connecting member 130 from moving relative to the translation member 120 from the first relatively static position along the second direction, thereby making the translation member 120 and the connecting member 130 stably maintained in the first relatively static position.

[0162] In some embodiments, the elastic element 140 is located on at least one side of the rack 152, that is, the elastic element 140 can be one located on one side of the rack 152, or the elastic element 140 can be two distributed on both sides of the rack 152.

[0163] like Figure 11 As shown, in some possible embodiments provided in this application, a first guide groove 123 is provided in the frame structure 121. The first guide groove 123 is located between the guide rail 122 and the rack 152, and the connector 130 is configured to move along the first guide groove 123.

[0164] The first guide groove 123 provides movement space for the elastic deformation of the elastic member 140 to drive the movement of the connecting member 130 relative to the translation member 120. In other words, when the connecting member 130 is in a first relatively stationary position, and the cleaning component 200 is obstructed, causing the elastic member 140 to deform, the elastic member 140 will drive the connecting member 130 to move along the first guide groove 123 relative to the translation member 120, thus buffering the damage to the cleaning component 200 and the transmission component from external forces. Simultaneously, the bottom of the connecting member 130 is exposed through the first guide groove 123 to facilitate connection with the cleaning component 200 located at the bottom of the cleaning device. It can be understood that the movement of the connecting member 130 along the first guide groove 123 relative to the translation member 120 can drive the cleaning component 200 to translate relative to the machine body. Specifically, the connecting member 130 is configured to slide or roll along the first guide groove 123.

[0165] like Figure 11 As shown, in the above embodiment, the guide rail 122 has a second guide groove 124 communicating with the first guide groove 123, and the connector 130 is configured to move along the second guide groove 124. The second guide groove 124 provides movement space for the connector 130 relative to the guide rail 122, and at the same time, exposes the bottom of the connector 130 through the second guide groove 124 to facilitate connection with the cleaning component 200 located at the bottom of the cleaning device. It can be understood that when the connector 130 is located in the second guide groove 124, the translation member 120 moves through the guide rail 122 to guide the connector 130 to rise or fall, thereby driving the cleaning component 200 to move up and down relative to the machine body in a third direction.

[0166] The connector 130 can move from the first guide groove 123 to the second guide groove 124, and the connector 130 can also move from the second guide groove 124 to the first guide groove 123, thereby causing the translation member 120 to move. This drives the cleaning assembly 200 to translate between the first working position and the second working position, to rise from the first working position to the initial position, and to descend from the output position to the first working position. Specifically, the connector 130 is configured to slide or roll along the second guide groove 124.

[0167] like Figure 8 and Figure 9 As shown, in some possible embodiments provided in this application, the limiting part 160 includes a baffle 161, which is located within the frame structure 121 and configured to be movable along the frame structure 121. The baffle 161 is located behind the connector 130 in the first direction. The first end of the elastic member 140 is connected to the frame structure 121, and the second end of the elastic member 140 is connected to the baffle 161.

[0168] Since the baffle 161 is located behind the connecting piece 130 along the first direction, and the elastic piece 140 connects the frame structure 121 and the baffle 161, the elastic piece 140 can transmit the force to the connecting piece 130 through the baffle 161 to keep the connecting piece 130 and the translation piece 120 in the first relatively static position, and meanwhile, the connecting piece 130 can transmit the external force in the second direction to the elastic piece 140 through the baffle 161 to make the elastic piece 140 deform, so that the cleaning assembly 200 moves in the second direction to buffer the impact of the external force, and improve the reliability of the cleaning assembly 200 and the lifting device 100, and the operation accuracy of the cleaning equipment. Specifically, the baffle 161 can slide along the frame structure 121, or the baffle 161 can roll along the frame structure 121.

[0169] In the above embodiment, the baffle 161 and the connecting piece 130 are in a split structure, which is convenient for maintenance and replacement, and is beneficial to save maintenance and replacement costs. It can be understood that in this case, the baffle 161 and the connecting piece 130 are in an abutting state under the action of the elastic piece 140.

[0170] In the above embodiment, the baffle 161 and the connecting piece 130 are in an integrated structure, which simplifies the assembly process and is beneficial to improve the assembly efficiency and production efficiency.

[0171] As shown in Figure 8 and Figure 11 In some possible implementation embodiments provided by the present application, the limiting part 160 further comprises a first blocking rib 125 arranged on the inner wall of the frame structure 121 opposite to the first guide groove 123, and the baffle 161 is in contact with the first blocking rib 125 to limit the relative movement of the connecting piece 130 and the translation piece 120 to keep the connecting piece 130 and the translation piece 120 in the first relatively static position. Therefore, through the cooperation of the baffle 161 and the first blocking rib 125, the reliability and stability of the connecting piece 130 and the translation piece 120 kept in the first relatively static position are improved, so as to improve the reliability and stability of the translation movement and the lifting movement of the cleaning assembly 200.

[0172] Specifically, the first blocking rib 125 is arranged in pairs on both sides of the inner wall of the frame structure 121, so that the two sides of the baffle 161 are in contact with the first blocking rib 125 to improve the reliability and stability of the limiting.

[0173] As shown in Figure 8 and Figure 11As shown in some possible implementation embodiments provided in the present application, the limiting portion 160 further comprises a second blocking rib 126 arranged on the inner wall of the frame structure 121 opposite to the first guide groove 123, the second blocking rib 126 is located behind the first blocking rib 125 in the first direction, and the baffle 161 is in contact with the second blocking rib 126 to limit the relative movement of the connecting member 130 and the translation member 120. Thus, by cooperation of the baffle 161 and the second blocking rib 126, the movement range of the connecting member 130 relative to the translation member 120 in the second direction can be limited, and the possibility of damage caused by the connecting member 130 moving beyond the range relative to the translation member 120 in the second direction and colliding with the frame structure 121 under the action of external force can be reduced or avoided, thereby playing a good protection role on the frame structure 121 and the connecting member 130, and being beneficial to improve the reliability of the lifting device 100.

[0183] In the sliding groove 111, the bottom of the sliding groove 111 is provided with an avoiding passage 112, the connecting member 130 is exposed in the avoiding passage 112, and the cleaning assembly 200 is connected with the connecting member 130 through the avoiding passage 112.

[0188] The length of the cover plate 180 is less than the length of the mounting base 110, and the length of the cover plate 180 is greater than the length of the translation member 120, so that the cover plate 180 shields part of the opening of the sliding groove 111 of the mounting base 110, and part of the translation member 120 is not shielded by the cover plate 180 to be exposed, facilitating the position of the translation member 120 to be known, such as facilitating the detection device to detect the position of the translation member 120, or facilitating the user to intuitively observe the position of the translation member 120.
