[0067] Example embodiments now will be described more fully hereinafter with reference to the accompanying drawings. Example embodiments, however, can be implemented in many different forms and should not be construed as limited to the implementations set forth herein; rather, these implementations are provided so that this disclosure will be thorough and complete, and will fully convey the scope of example embodiments to those skilled in the art. Like reference numerals refer to like elements throughout the figures, and thus description of the same will not be repeated.

[0068] Although relative terms are used in this description, such as "upper," "lower," to describe one component's relationship to another component, such terms are used herein for convenience only and are not intended to limit the scope of the disclosure to a particular orientation. It is to be understood that the disclosed devices can be inverted, such that the upper component becomes the lower component, and the lower component becomes the upper component. When a structure is "on" another structure, it can mean that the structure is formed integrally with the other structure, or that the structure is "directly" on the other structure, or that the structure is "indirectly" on the other structure by way of another structure.

[0069] The terms "a," "an," "the" and "said" are used to mean one or more, unless otherwise indicated; the terms "including" and "having" are used to mean open-ended including, and are not limited to the listed elements or components; the terms "first," "second," and the like specify numbering only and do not indicate quantity or limit a number of objects.

[0070] As shown in Figures 1 to 6 The present disclosure first provides a cleaning device, which can include a carrying device and a cleaning device. The cleaning device can be a robot vacuum cleaner, a floor washing machine, a dust collector, a sweeping and mopping all-in-one machine, a window cleaning robot, etc. The cleaning device can include a cleaning part, which can be a roller brush, an edge brush, a water outlet, a mopping element, a window cleaning element, etc., for cleaning a surface to be cleaned.

[0071] As shown in Figure 1 The carrying device can include a main body part 1 and a rotating mechanism 2. As shown in Figure 2 The main body part 1 can be provided with a receiving cavity 11 capable of accommodating the cleaning device and a first cleaning through hole 12 capable of exposing the cleaning part of the cleaning device. The main body part 1 can also be provided with a walking assembly for moving and climbing.

[0072] The rotating mechanism 2 can be mounted on the main body 1, and at least part of the rotating mechanism 2 can be located in the accommodating cavity 11, or at least part of the rotating mechanism 2 can be located in the first cleaning through hole 12, or at least part of the rotating mechanism 2 can be located in the accommodating cavity 11 and the first cleaning through hole 12 at the same time, and at least part of the rotating mechanism 2 can be in contact with the cleaning device. The rotating mechanism 2 can be configured to drive the cleaning device to rotate relative to the main body 1 in a first direction X or a direction opposite to the first direction X, and the first direction X can be a direction around the central axis of the first cleaning through hole 12. That is, it can be understood that the rotating mechanism 2 can drive the cleaning device to rotate relative to the main body 1 in the first direction X or the direction opposite to the first direction X through the part in contact with the cleaning device. The first direction X can be a clockwise direction, and the direction opposite to the first direction X can be a counterclockwise direction; or, the first direction X can be a counterclockwise direction, and the direction opposite to the first direction X can be a clockwise direction.

[0073] It should be noted that the "contact" described above should be understood as: the surfaces of the two structures are in close contact with each other, or there is a connection relationship between the two structures, or the two structures abut against each other, or the two structures engage with each other, or the two structures are clamped with each other, etc.

[0074] In the cleaning device, the cleaning device can be located in the accommodating cavity 11 and can be in contact with the rotating mechanism 2. The cleaning part of the cleaning device can be exposed through the first cleaning through hole 12 of the main body 1 to clean the surface to be cleaned by the exposed cleaning part.

[0075] The carrying device provided by the present disclosure is provided with an accommodating cavity 11 capable of accommodating a cleaning device, so that the cleaning device can be transported to different floors by the carrying device, so that the cleaning device can clean different floors, and the cleaning range of the cleaning device is improved. At the same time, the main body 1 is also provided with a first cleaning through hole 12 capable of exposing the cleaning part of the cleaning device, so that the cleaning device can still clean the surface to be cleaned such as steps and railings in the accommodating cavity 11 during the movement and climbing of the carrying device, thereby further improving the cleaning range of the cleaning device. And the cleaning device does not need to leave the accommodating cavity 11 of the carrying device to complete the cleaning work, which can save the time and process of the cleaning device leaving and re-entering the carrying device, thereby improving the cleaning efficiency and the climbing efficiency of the carrying device.

[0076] Secondly, the rotating mechanism 2 arranged in the bearing device can enable the cleaning device to rotate in the accommodating cavity 11 of the bearing device. Therefore, when the cleaning device cleans the surface to be cleaned, the rotating mechanism 2 can rotate the cleaning device, so as to further improve the cleaning range of the cleaning device, thereby further improving the cleaning effect.

[0077] In some embodiments, as shown in Figure 3 The tray 21 can be rotatably installed in the first cleaning through hole 12 and configured to support the cleaning device. In this way, the second tray 21 can be used to support the cleaning device, so as to improve the supporting force of the bearing device and avoid the problem of falling of the cleaning device. At the same time, the tray 21 can also protect the bottom surface of the cleaning device, so as to avoid damage of the cleaning device by hard objects on the surface to be cleaned.

[0078] The tray 21 can be provided with a second cleaning through hole 211, and the cleaning part of the cleaning device can be exposed through the second cleaning through hole 211, for example, the second cleaning through hole 211 can expose the bristles of the rolling brush and the edge brush of the cleaning device. In this way, the tray 21 can avoid shielding the cleaning part, so as to ensure the cleaning effect of the cleaning device in the bearing device.

[0079] Further, when the cleaning device comprises multiple cleaning parts, the second cleaning through hole 211 can be divided into multiple sub-through holes, and each sub-through hole can expose one cleaning part. For example, when the cleaning device comprises a rolling brush and an edge brush, the second cleaning through hole 211 can be divided into two sub-through holes, i.e., a first sub-through hole 2111 and a second sub-through hole 2112, the first sub-through hole 2111 can be used to expose the rolling brush, and the second sub-through hole 2112 can be used to expose the bristles of the edge brush. In this way, when the cleaning device comprises multiple cleaning parts, the sub-through holes arranged at intervals can be used to expose the cleaning parts corresponding to the sub-through holes, so as to avoid using a second cleaning through hole 211 with a large opening area to expose all the cleaning parts. Therefore, the opening area of the second through hole can be reduced, the area ratio of the second cleaning through hole 211 on the tray 21 can be reduced, so as to provide a larger supporting area for the solid structure on the tray 21, thereby improving the bearing capacity and structural strength of the tray 21, further avoiding the problem of falling of the cleaning device, and further avoiding damage of the cleaning device by hard objects on the surface to be cleaned.

[0080] The rotating mechanism 2 can further comprise a driving part 22. The driving part 22 can be installed on the main body part 1 and in contact with the tray 21, so as to drive the tray 21 to rotate relative to the main body part 1 along the first direction X or the direction opposite to the first direction X.

[0081] The driving part 22 can include a transmission part 221 and a driving part 222. The transmission part 221 can be in contact with the tray 21 for driving the tray 21 to rotate. The driving part 222 can be connected with the transmission part 221 for driving the transmission part 221 to rotate relative to the main body part 1 along the first direction X or a direction opposite to the first direction X. In this way, by providing the transmission part 221 and using the transmission part 221 to transmit the driving force provided by the driving part 222, the flexibility of the arrangement position of the driving part 222 in the accommodating cavity 11 can be improved, and the arrangement difficulty of each component in the bearing device can be reduced. The driving part 222 can be a driving motor, and a driving shaft of the driving motor can be connected with the transmission part 221 to output the driving force to the transmission part 221.

[0082] In some embodiments, a part of the outer circumferential surface of the transmission part 221 can be in contact with a part of the outer circumferential surface of the tray 21 for driving the tray 21 to rotate. The driving part 222 can be located at the end surface side of the transmission part 221, and the driving part 222 can be connected with the end surface of the transmission part 221. Since there are more components arranged in the length direction and / or the width direction of the accommodating cavity 11, the component arrangement space in the length direction and / or the width direction of the accommodating cavity 11 is relatively crowded. However, there are fewer components arranged in the height direction of the accommodating cavity 11, and the driving part 222 is arranged at the end surface side of the transmission part 221 in this embodiment, so that the driving part 222 and the transmission part 221 can be arranged in the height direction of the accommodating cavity 11, thereby saving the space of the accommodating cavity 11 in the length direction or the width direction, reducing the length and / or width of the bearing device, and reducing the arrangement difficulty of each component in the bearing device.

[0083] In some embodiments, as shown in Figure 3 The tray 21 can include a supporting part 212 and a first tooth part 213. The supporting part 212 can be used to support the cleaning device, and the second cleaning through hole 211 can be located at the supporting part 212. The first tooth part 213 can be arranged on at least part of the outer circumferential surface of the supporting part 212. The first tooth part 213 can include a plurality of teeth, and the spacing between any two adjacent teeth can be the same, but is not limited thereto.

[0084] At least part of the outer circumferential surface of the transmission part 221 can be provided with a second tooth part 2211, and the first tooth part 213 can be engaged with the second tooth part 2211. In this way, the force transmission between the transmission part 221 and the tray 21 can be realized, so that the transmission part 221 can drive the tray 21 to rotate. At the same time, by providing the first tooth part 213 and the second tooth part 2211, the stability of the contact between the transmission part 221 and the tray 21 can be improved, so that the transmission part 221 can stably transmit the driving force to the tray 21, and the smoothness and continuity of the rotation of the tray 21 can be improved. The second tooth part 2211 can also include a plurality of teeth, and the spacing between any two adjacent teeth can be the same, but is not limited thereto.

[0085] In other embodiments, the tray 21 can also not be provided with the first tooth portion 213, and the transmission member 221 can also not be provided with the second tooth portion 2211. For example, the outer circumferential surface of the supporting portion 212 and the outer circumferential surface of the transmission member 221 can also be provided as surfaces with high friction. By contacting the outer circumferential surfaces with high friction, the driving force can be transmitted by friction, and the purpose of rotating the tray 21 by the transmission member 221 can also be achieved. Alternatively, a transmission belt or a transmission chain can be sleeved on the outer circumferential surface of the supporting portion 212 and the outer circumferential surface of the transmission member 221. The transmission member 221 can drive the transmission belt or the transmission chain to move, so as to drive the supporting portion 212 to rotate by the transmission belt or the transmission chain. This can also achieve the purpose of rotating the tray 21 by the transmission member 221, but is not limited thereto.

[0086] In some embodiments, as shown in Figure 3 The supporting portion 212 can further include a bearing ring 2121 and a supporting plate 2122. The first tooth portion 213 can be arranged on at least part of the outer circumferential surface of the bearing ring 2121.

[0087] The first tooth portion 213 and the bearing ring 2121 can be an integral structure, that is, the first tooth portion 213 and the bearing ring 2121 can be made by an integral process, without the need to connect them into an integral structure by bonding, welding, riveting, screw connection or the like. In this way, the connection points between the first tooth portion 213 and the outer circumferential surface of the bearing ring 2121 can be reduced, and the connection strength between the first tooth portion 213 and the outer circumferential surface of the bearing ring 2121 can be improved. Thus, the structural strength of the supporting portion 212 can be improved, the stability of the driving force transmission can be further improved, and the service life of the rotating mechanism 2 and even the entire bearing device can be improved.

[0088] However, the first tooth portion 213 and the bearing ring 2121 can also be a split structure, that is, the first tooth portion 213 and the bearing ring 2121 can be manufactured separately, and then connected into an integral structure by bonding, welding, riveting, screw connection or the like. In this way, the manufacturing difficulty of the first tooth portion 213 and the bearing ring 2121 can be reduced.

[0089] The supporting plate 2122 can be arranged on the side of the bearing ring 2121 away from the accommodating cavity 11, and the supporting plate 2122 can be connected with the bearing ring 2121. The second cleaning through hole 211 can be located on the supporting plate 2122, so as to support the cleaning device by the supporting plate 2122.

[0090] As shown in Figure 3 and Figure 4As shown, the projection of the supporting plate 2122 in the second direction Y can be located within the range of the projection of the bearing ring 2121 in the second direction Y, and the second direction Y can be the extension direction of the central axis of the bearing ring 2121. That is, it can be understood that the area of the projection of the supporting plate 2122 in the second direction Y is smaller than the area of the projection of the bearing ring 2121 in the second direction Y. In this way, the setting area of the supporting plate 2122 can be reduced as much as possible while ensuring that the supporting plate 2122 has sufficient supporting force and structural strength, so that the manufacturing cost of the supporting plate 2122 can be reduced. At the same time, such an arrangement can also avoid the problem of blocking or positional interference with the traveling part of the cleaning device due to the excessive setting area of the supporting plate 2122.

[0091] In some embodiments, the bearing ring 2121 can also have a reinforcing plate, which can be arranged on part of the inner circumferential surface of the bearing ring 2121 to improve the structural strength of the bearing ring 2121. At the same time, the orthographic projection of the reinforcing plate in the second direction Y can overlap the orthographic projection of the supporting plate 2122 in the second direction Y, and the supporting plate 2122 can be connected with the reinforcing plate to achieve the purpose of connecting the supporting plate 2122 with the bearing ring 2121. In this way, the connecting area between the supporting plate 2122 and the bearing ring 2121 can be increased, the connecting strength between the supporting plate 2122 and the bearing ring 2121 can be improved, and the connecting difficulty between the supporting plate 2122 and the bearing ring 2121 can be reduced.

[0092] The supporting plate 2122 and the reinforcing plate can be connected by screws, so that the supporting plate 2122 can be easily disassembled and installed. When the supporting plate 2122 or the bearing ring 2121 is damaged, the supporting plate 2122 and the bearing ring 2121 can be separated, and only the damaged parts can be replaced, thereby reducing the maintenance cost of the bearing device. However, the supporting plate 2122 and the reinforcing plate can also be connected by bonding, welding or other connection methods, which are also within the protection scope of the present disclosure.

[0093] In some embodiments, as shown in Figs. 2 and 3, Figure 3 and Figure 4 The bearing device can also include a position detector 3. The position detector 3 can be installed on the main body 1 and located in the accommodation cavity 11. The position detector 3 can be configured to detect the rotational position of the tray 21. In this way, the rotational position of the tray 21 at this time can be accurately determined by using the position detector 3, so that the rotational orientation of the cleaning device at this time can be accurately determined.

[0094] The bearing device can further include a controller, which can be a processor or the like, but is not limited thereto. The controller can be disposed on the main body or the rotating mechanism, and the controller can be connected with the position detector 3. For example, the controller can be connected with the position detector 3 through a signal transmission line, or the controller can be wirelessly connected with the position detector 3 through Bluetooth, a wireless network, a mobile network, or the like.

[0095] The controller can be configured to control the tray 21 to stop rotating when the position detector 3 detects that the tray 21 rotates to a preset position. In this way, the rotating position of the tray 21 can be accurately controlled, and the orientation of the cleaning device can be accurately controlled by the position detector 3 and the controller, so that the cleaning device cannot rotate to an optimal cleaning angle due to over-rotation or insufficient rotation of the tray 21, thereby ensuring the cleaning effect of the cleaning device on the surface to be cleaned.

[0096] The tray 21 can include at least one position marker 214, the position detector 3 can be configured to detect the position of the position marker 214, and the controller can be configured to control the tray 21 to stop rotating when the position detector 3 detects that the position marker 214 rotates to a preset position. In this embodiment, by providing the position marker 214, the accuracy of the position detector 3 can be improved, and the accuracy of the rotating angle of the tray 21 and the cleaning device can be improved, thereby further improving the cleaning effect of the cleaning device on the surface to be cleaned.

[0097] As shown in FIG. 1, Figure 4 The tray 21 can include a first position marker 2141 and a second position marker 2142, and the first position marker 2141 and the second position marker 2142 can be disposed at intervals along the circumferential direction of the tray 21. When the position detector 3 detects the first position marker 2141, the controller can control the tray 21 to stop rotating, so that the cleaning device rotates to a first cleaning position at this time, and the surface to be cleaned is cleaned at the first cleaning position. When the position detector 3 detects the second position marker 2142, the controller can control the tray 21 to stop rotating, so that the cleaning device rotates to a second cleaning position at this time, and the surface to be cleaned is cleaned at the second cleaning position. In this way, by providing a plurality of position markers 214, different rotating positions of the tray 21 can be accurately controlled according to cleaning needs, different cleaning positions of the cleaning device can be accurately controlled according to cleaning needs, and the cleaning effect of the cleaning device can be improved.

[0098] The minimum included angle a between the first position marker 2141 and the second position marker 2142 can be greater than or equal to 10° and less than or equal to 180°, for example, the minimum included angle a between the first position marker 2141 and the second position marker 2142 can be 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, 90°, 100°, 110°, 120°, 130°, 140°, 150°, 160°, 170°, 180°, etc. In this way, the cleaning device can have a larger cleaning range.

[0099] In some embodiments, the controller can be in communication connection with the driving part 22, for example, the controller can be in communication connection with the driving part 22 through signal transmission lines, or the controller can be in communication connection with the driving part 22 through Bluetooth, wireless network, mobile network, etc. Communication mode to control the opening or closing of the driving part 22.

[0100] When the position detector 3 detects that the position marker 214 rotates to the preset position, the controller can control the driving part 22 to pause applying driving force to the tray 21, so as to automatically control the tray 21 to stop rotating. That is, when the position detector 3 detects that the position marker 214 rotates to the preset position, the controller can send a control signal to the driving part 22, and the driving part 22 can immediately stop working after receiving the control signal, so as to control the tray 21 to stop rotating.

[0101] Moreover, when the tray 21 is provided with the first tooth part 213 and the transmission part 221 is provided with the second tooth part 2211, the transmission part 221 will immediately stop rotating when the driving part 222 stops working. At this time, due to the meshing between the first tooth part 213 and the second tooth part 2211, the second tooth part 2211 on the transmission part 221 will immediately block the movement of the first tooth part 213 on the tray 21, so as to immediately stop the rotation of the tray 21. Therefore, when the tray 21 is provided with the first tooth part 213 and the transmission part 221 is provided with the second tooth part 2211, the rotation position of the tray 21 can be more accurately controlled, and the rotation direction of the cleaning device can be more accurately controlled.

[0102] The position detector 3 can be a photoelectric switch, and the position marker 214 can be a light barrier or a reflective plate. The light barrier can shield light, and the reflective plate can reflect the light emitted by the photoelectric switch.

[0103] When the position marker 214 is a light barrier, the light barrier will shield external light. When the photoelectric switch cannot receive external light or the amount of light received by the photoelectric switch decreases, it can be determined that the position marker 214 rotates to the preset position, and at this time the controller can control the driving part 22 to pause applying driving force to the tray 21.

[0104] When the position marker 214 is a light barrier, the light barrier can reflect the light emitted by the photoelectric switch. When the photoelectric switch receives the reflected light, it can be determined that the position marker 214 has rotated to the preset position, and at this time the controller can control the driving part 22 to pause the application of the driving force to the tray 21.

[0105] However, the position detector 3 can also be other types of sensors, such as a vision sensor, etc. The position marker 214 can also be other types of position markers 214, such as a position mark, etc. The selection and setting can be made according to the actual situation, which is within the protection scope of the present disclosure.

[0106] In some embodiments, as shown in Figure 3 and Figure 4 The position detector 3 can be arranged at the preset position of the rotation of the position marker 214, so as to improve the accuracy of the detection of the rotation position of the position marker 214.

[0107] In some embodiments, the position marker 214 can be arranged on the carrier ring 2121, so as to improve the integration of the tray 21. When the position marker 214 is a light barrier or a light barrier, the position marker 214 can be arranged on the end face of the carrier ring 2121.

[0108] The light barrier or the light barrier and the carrier ring 2121 can be an integrated structure, that is, the light barrier or the light barrier and the carrier ring 2121 can be made by an integrated process, without the need to use bonding, welding, riveting, screw connection and other connection methods to connect the two into one. In this way, the connection points between the light barrier or the light barrier and the carrier ring 2121 can be reduced, and the connection strength between the light barrier or the light barrier and the carrier ring 2121 can be improved.

[0109] However, the light barrier or the light barrier and the carrier ring 2121 can also be a split structure, that is, the light barrier or the light barrier and the carrier ring 2121 can be manufactured separately, and then connected into one by bonding, welding, riveting, screw connection and other connection methods. In this way, the manufacturing difficulty of the light barrier or the light barrier and the carrier ring 2121 can be reduced.

[0110] In some embodiments, the cleaning part can include a side brush, and the second cleaning through hole of the tray 21 can expose the bristles of the side brush of the cleaning device. The side brush can be configured to rotate the bristles during the cleaning process to clean the surface to be cleaned.

[0111] As shown in Figure 4 and Figure 5As shown, the carrying device can further include a guide structure 4, which can be arranged on the main body 1 or the tray 21. The guide structure 4 can be configured to press the bristles during the rotation of the side brush to guide the bristles to the surface to be cleaned, so that the bristles are always in contact with the surface to be cleaned. In this way, the cleaning device can still use the side brush to clean the surface to be cleaned when the carrying device is on the carrying device. In this way, the function of cleaning the surface to be cleaned such as stairs, railings, etc. by the cleaning device during the walking or climbing of the carrying device can be realized. Therefore, the cleaning range of the cleaning device can be further improved, so as to further improve the cleaning effect and the use experience of the user.

[0112] In some embodiments, at least part of the guide structure 4 can be located on the side of the second cleaning through hole away from the center of the main machine of the cleaning device and on the rotation path of the bristles.

[0113] The rotation path of the bristles can include a first rotation path and a second rotation path. When the bristles rotate along the first rotation path, the bristles can gradually move away from the center of the main machine of the cleaning device. When the bristles rotate along the second rotation path, the bristles can gradually move towards the center of the main machine of the cleaning device. It can be understood that the first rotation path and the second rotation path are respectively part of the rotation path of the bristles, and the bristles need to rotate along the first rotation path and the second rotation path for one rotation.

[0114] The above-mentioned guide structure 4 can be located on the first rotation path to press the bristles by the guide structure 4 when the bristles rotate away from the center of the main machine of the cleaning device, so that the bristles can sweep the dirt on the surface to be cleaned to the lower side of the cleaning main machine, thereby improving the cleaning effect.

[0115] The guide structure 4 can include a guide surface 42. The guide surface 42 can be located on the first rotation path, and the guide surface 42 can be configured to press the bristles during the rotation of the bristles along the first rotation path to guide the bristles to the surface to be cleaned.

[0116] The guide surface 42 can have a first end and a second end, and the distance between the first end of the guide surface 42 and the rotation axis of the bristles can be less than or equal to the rotation radius of the bristles, and the second end of the guide surface 42 is closer to the rotation axis of the bristles relative to the first end. Among them, the bristles can contact the guide surface 42 from the first end of the guide surface 42 during the rotation, and separate from the guide surface 42 from the second end of the guide surface 42. In this way, the distance between the second end of the guide surface 42 and the rotation axis of the bristles can be ensured to be less than the rotation radius of the bristles, so that the guide surface 42 can continuously press the bristles to improve the guiding effect of the guide surface 42.

[0117] The distance between the guide surface 42 and the rotation axis of the brush hair can gradually decrease from the first end to the second end. In this way, the guide surface 42 can gradually increase the amount of extrusion on the brush hair, so that the brush hair can be gradually bent to the required bending angle, avoiding damage to the brush hair due to too rapid change in the bending angle.

[0118] Between the first end and the second end, the guide surface 42 can be a curved surface, so that the guide surface 42 can change the amount of extrusion on the brush hair more smoothly, and the guiding effect of the guide surface 42 on the brush hair can be improved. However, the guide surface 42 can also be a flat surface between the first end and the second end, which is also within the protection scope of the present disclosure.

[0119] In some embodiments, the distance between the end of the guide surface 42 close to the surface to be cleaned and the rotation axis of the brush hair can be less than or equal to the rotation radius of the brush hair. The end of the guide surface 42 away from the surface to be cleaned is closer to the rotation axis of the brush hair than the end of the guide surface 42 close to the surface to be cleaned. In this way, the shape of the guide surface 42 can be more matched to the setting angle of the brush hair, and the smoothness of the guiding of the guide surface 42 on the brush hair can be further improved.

[0120] The distance between the guide surface 42 and the rotation axis of the brush hair gradually decreases from the end of the guide surface 42 away from the surface to be cleaned to the end of the guide surface 42 close to the surface to be cleaned, so as to further match the setting angle of the brush hair, thereby further improving the smoothness of the guiding of the guide surface 42 on the brush hair and further improving the guiding effect.

[0121] Further, between the end of the guide surface 42 away from the surface to be cleaned and the end of the guide surface 42 close to the surface to be cleaned, the guide surface 42 can be a curved surface, so that the guide surface 42 can change the amount of extrusion on the brush hair more smoothly, and the guiding effect of the guide surface 42 on the brush hair can be further improved. However, the guide surface 42 can also be a flat surface between the end of the guide surface 42 away from the surface to be cleaned and the end of the guide surface 42 close to the surface to be cleaned, which is also within the protection scope of the present disclosure.

[0122] In some embodiments, the distance between the end of the brush hair close to the surface to be cleaned and the surface to be cleaned can be less than the distance between the end of the guide surface 42 close to the surface to be cleaned and the surface to be cleaned. In this way, it can be further ensured that the guide surface 42 can guide the brush to the surface to be cleaned.

[0123] When the guide surface 42 does not extrude the brush hair, the distance between the end of the brush hair close to the surface to be cleaned and the surface to be cleaned can be less than or equal to 2 cm. In this way, it can be further ensured that the guide surface 42 can guide the brush hair to the surface to be cleaned.

[0124] In some embodiments, the distance between the end of the guide surface 42 away from the surface to be cleaned and the surface to be cleaned can be greater than the distance between most of the bristles and the surface to be cleaned, thereby providing a more stable guiding effect.

[0125] The guide structure 4 can be set on the bearing ring 2121, but is not limited thereto. The guide structure 4 can also be set on the support plate 2122, or the guide structure 4 can be set on both the bearing ring 2121 and the support plate 2122 at the same time, so as to provide a stable setting position for the guide structure 4.

[0126] Furthermore, the guide structure 4 can be disposed on the inner circumferential surface of the bearing ring 2121 so that the guide surface 42 is located on the rotation path of the bristles.

[0127] In some embodiments, the guide structure 4 can be a guide block 41, but it is not limited to this. The guide structure 4 can also be a guide plate or other structures, as long as the guide structure 4 has a guide surface.

[0128] In some embodiments, when the bristles are squeezed by the guide structure 4, the bending angle of the bristles can be greater than or equal to 10° and less than or equal to 120°. Examples include: 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, 90°, 100°, 110°, 120°, etc. This configuration ensures that the bristles are guided and come into contact with the surface to be cleaned after being squeezed.

[0129] In some embodiments, the carrier device may further include a guide structure 5. The guide structure 5 may have a guide surface 52, one end of which may be connected to a first end of a guide surface 42, and the distance between the end of the guide surface 52 away from the first end of the guide surface 42 and the rotation axis of the bristles may be greater than the rotation radius of the bristles.

[0130] In other words, since the distance between the first end of the guide surface 42 and the rotation axis of the bristles is less than or equal to the rotation radius of the bristles, the distance between the end of the guide surface 52 connected to the first end of the guide surface 42 and the rotation axis of the bristles can also be less than or equal to the rotation radius of the bristles. Since the distance between the end of the guide surface 52 away from the guide surface 42 and the rotation axis of the bristles can be greater than the rotation radius of the bristles, the guide surface 52 can smoothly receive the rotating bristles, guiding them smoothly to the first end of the guide plate. This provides better guidance and protection for the bristles.

[0131] Furthermore, the projection of the end of the guide surface 52 away from the guide surface 42 in the second direction Y can be located on the support plate 2122, so as to ensure that the distance between the end of the guide surface 52 away from the guide surface 42 and the rotation axis of the bristles can be greater than the rotation radius of the bristles.

[0132] The guide structure 5 can be connected with the guide structure 4, so that the guide surface 52 can be connected with the guide surface 42. The guide structure 5 can be a guide block 51, but is not limited thereto. The guide structure 5 can also be a guide plate or other structure, as long as the guide structure 5 has the guide surface 52.

[0133] In some embodiments, the carrying device can further include a limiting structure 6, which can be arranged on the main body 1 or the tray 21. The limiting structure 6 can have a limiting surface 61, which is close to the rotation axis of the bristles relative to the hole wall of the second cleaning through hole 211, and one end of the limiting surface 61 can be connected with the second end of the guide surface 42. In this way, the bristles separated from the guide surface 42 can be continuously pressed by the limiting surface 61, so as to ensure the bending shape of the bristles, thereby ensuring that the bristles can also contact the surface to be cleaned after being separated from the guide surface 42, and thus the cleaning effect of the cleaning device can be improved.

[0134] In some embodiments, the end of the limiting surface 61 close to the surface to be cleaned can be away from the surface to be cleaned relative to the end of the guide surface close to the surface to be cleaned, so as to ensure the limiting effect of the limiting surface 61 on the bristles.

[0135] The limiting structure 6 can be arranged on the bearing ring 2121, but is not limited thereto. The limiting structure 6 can also be arranged on the bearing plate 2122, or the limiting structure 6 can be arranged on both the bearing ring 2121 and the bearing plate 2122, so as to provide a stable arrangement position for the limiting structure 6.

[0136] Further, the limiting structure 6 can be arranged on the inner circumferential surface of the bearing ring 2121, so as to make the limiting surface 61 close to the rotation axis of the bristles relative to the hole wall of the second cleaning through hole 211.

[0137] In some embodiments, the limiting structure 6 can be a limiting block, but is not limited thereto. The limiting structure 6 can also be a limiting plate or other structure, as long as the limiting structure 6 has the limiting surface 61.

[0138] In some embodiments, the bearing ring 2121, the guide structure 4, the guide structure 5 and the limiting structure 6 can be an integrated structure, that is, the bearing ring 2121, the guide structure 4, the guide structure 5 and the limiting structure 6 can be made by an integrated process, without the need to connect each part into an integrated whole by bonding, welding, riveting, screw connection or the like. In this way, the number of connection points between the guide structure 4, the limiting structure 6 and the inner circumferential surface of the bearing ring 2121 can be reduced, the connection strength between the guide structure 4, the limiting structure 6 and the inner circumferential surface of the bearing ring 2121 can be improved, and the probability of the guide structure 4 and the limiting structure 6 falling off can be reduced, so that the service life of the guide structure 4 and the limiting structure 6 can be improved. At the same time, in this way, the number of connection points between the guide structure 4 and the guide structure 5 can be reduced, the connection strength between the guide structure 4 and the guide structure 5 can be improved, and the probability of the guide structure 4 and the guide structure 5 falling off can be reduced.

[0139] But not limited to this, the bearing ring 2121, the guide structure 4, the guide structure 5 and the bearing ring 2121 can also be a split structure, that is, the bearing ring 2121, the guide structure 4, the guide structure 5 and the bearing ring 2121 can be manufactured separately, and then connected into an integrated whole by bonding, welding, riveting, screw connection or the like. In this way, the manufacturing difficulty of the bearing ring 2121, the guide structure 4, the guide structure 5 and the bearing ring 2121 can be reduced.

[0140] In some embodiments, as shown in Figure 6 The inner wall of the first cleaning through hole 12 can be provided with a first connecting part 13, and the tray 21 can be provided with a second connecting part 215. The tray 21 and the main body part 1 can be connected by sliding through the first connecting part 13 and the second connecting part 215, and the second connecting part 215 can rotate relative to the first connecting part 13, so that the tray 21 can rotate relative to the main body part 1. By providing the first connecting part 13 and the second connecting part 215, the connection strength between the tray 21 and the main body part 1 can be improved, and the stability of the tray 21 can be improved, and the probability of the tray 21 falling off can be reduced.

[0141] The second connecting part 215 can be located on the supporting part 212 of the tray 21, for example, the first connecting part 13 can be arranged on at least part of the outer circumferential surface of the bearing ring 2121, so that the bearing ring 2121 is connected with the main body part 1 by sliding.

[0142] The first connecting part 13 can be a sliding block, and the second connecting part 215 can be a sliding groove. The sliding block can extend into the sliding groove and be in sliding connection with the sliding groove. Alternatively, the first connecting part 13 can be a sliding groove, and the second connecting part 215 can be a sliding block. The sliding block can extend into the sliding groove and be in sliding connection with the sliding groove. However, the first connecting part 13 and the second connecting part 215 can also not be a sliding block and a sliding groove, but can be other structures capable of sliding connection, such as a pulley, and the like. The present disclosure does not make a specific limitation thereon, and the selection and setting can be made according to actual conditions. This is within the protection scope of the present disclosure.

[0143] As shown in Figures 7 to 9 Some embodiments of the present disclosure provide a control method of a bearing device, which can be used to control the bearing device described above.

[0144] It should be noted that the specific structure and beneficial effects of the bearing device have been described in detail in the above embodiments. Therefore, in the present embodiment, the specific structure and beneficial effects of the bearing device will not be described again, and reference can be made to the specific description in the above embodiments. This is within the protection scope of the present disclosure.

[0145] As shown in Figure 7 The control method of the bearing device can include:

[0146] In step S10, the cleaning demand information is obtained.

[0147] In step S20, a cleaning instruction is generated according to the cleaning demand information. The cleaning instruction includes a rotating cleaning instruction.

[0148] In step S30, the controller controls the rotating mechanism 2 to drive the cleaning device to rotate in the first direction X in response to the rotating cleaning instruction.

[0149] The bearing device is controlled by the control method of the bearing device, the cleaning range of the cleaning device is improved, and thus the cleaning effect can be further improved.

[0150] In step S10, the cleaning demand information includes position information of the bearing device, dirt condition information of a surface to be cleaned, and the like. The position information of the bearing device can include whether the bearing device climbs to a new position, and the like.

[0151] In step S20, the position information of the bearing device can be identified. When the bearing device climbs to a new position, a rotating cleaning instruction can be generated.

[0152] In step S30, when the controller responds to the rotating cleaning instruction, the controller can control the driving part 22 to work to drive the tray 21 to rotate, so as to drive the rotation of the cleaning device by the rotation of the tray 21.

[0153] Further, when the driving part 22 comprises the driving member 222 and the transmission member 221, the controller can control the driving member 222 to work, so as to drive the transmission member 221 to rotate by the driving member 222, and drive the tray 21 to rotate by the transmission member 221.

[0154] In some embodiments, the cleaning instruction can further comprise a reset instruction. As shown in Figure 8 The control method of the bearing device can further comprise:

[0155] At step S40, the controller controls the rotating mechanism 2 to drive the cleaning device to rotate in the direction opposite to the first direction X in response to the reset instruction. Thus, the controller can control the cleaning device to return to the initial position, so as to facilitate the next cleaning work.

[0156] In some embodiments, as shown in Figure 9 The control method of the bearing device can further comprise:

[0157] At step S50, the position detector 3 detects the rotating position of the tray 21.

[0158] At step S60, the controller controls the tray 21 to stop rotating when the position detector 3 detects that the tray 21 rotates to the preset position.

[0159] Specifically, when the tray 21 comprises at least one position marker 214, the position detector 3 can detect the position of the position marker 214; when the position detector 3 detects that the position marker 214 rotates to the preset position, it can be considered that the tray 21 rotates to the preset position, and at this time, the controller can control the tray 21 to stop rotating.

[0160] For example, when the position detector 3 detects that the tray 21 rotates to the preset position, the controller can send a control signal to the driving part 22, and the driving part 22 can stop working immediately after receiving the control signal, so as to achieve the purpose of controlling the tray 21 to stop rotating.

[0161] In some embodiments, as shown in Figure 10 Before step S20, the control method of the bearing device can further comprise:

[0162] At step S70, the position of the cleaning device is detected.

[0163] At step S80, when the cleaning device is located in the containing cavity 11, the subsequent steps are executed.

[0164] Further, in step S80, when the cleaning device is not located in the containing cavity 11, the subsequent steps are stopped from being executed. In this way, the rotating mechanism 2 can be prevented from idling when the cleaning device is not located in the containing cavity 11, so that the energy consumption of the bearing device can be saved. Meanwhile, in this way, the rotating mechanism 2 can also be prevented from rotating when the cleaning device is not completely located in the containing cavity 11, so that the cleaning device can be prevented from being damaged.

[0169] The program codes contained on the computer readable storage medium can be transmitted by any appropriate medium, including but not limited to wireless, wired, optical cable, RF, etc., or any appropriate combination thereof.

[0170] The program code for carrying out operations of the present application can be written in any combination of one or more programming languages, including an object oriented programming language.

[0171] In some embodiments, a carrying device is provided. The carrying device can include, but is not limited to, one or more processors and one or more memories.

The carrying device can include a main body 1 and a tray 21, the tray 21 can be installed on the main body 1, and the tray 21 can be configured to support the cleaning device, so that the cleaning device can be transported to different floors by the carrying device, so that the cleaning device can clean different floors, and the cleaning range of the cleaning device is improved. At the same time, the tray 21 is also provided with a second cleaning through hole 211 capable of exposing the brush bristles of the side brush, so that the cleaning device can still clean the cleaning surface such as steps and railings on the tray 21 during the movement and climbing of the carrying device, thereby further improving the cleaning range of the cleaning device. And the cleaning device does not need to leave the carrying device to complete the cleaning work when cleaning the cleaning surface, which can save the time and process of the cleaning device leaving and re-entering the carrying device, thereby improving the cleaning efficiency and the climbing efficiency of the carrying device.

[0175] The program code for carrying out operations of the present application can be written in any combination of one or more programming languages, including an object oriented programming language.
