[0001] The present application relates to the technical field of cleaning equipment, in particular to a cleaning base station and a cleaning system. BACKGROUND

The base station main body comprises a base, the first support assembly and the second support assembly are arranged on the base in a first direction; the first support assembly comprises a one-way roller and a first roller, the one-way roller and the first roller are arranged on the base in the first direction, the one-way roller is arranged on the side of the first roller away from the second support assembly; the first roller and the one-way roller are both used for bearing the rear wheels; when the rear wheels move forward, the one-way roller is in a slipping state; when the rear wheels move backward, the one-way roller is in a clamping state; The second support assembly is used for bearing the front wheels, or is used for supporting the front end of the wheeled robot, so that the front wheels are suspended relative to the base; The first spray head is used for cleaning the rear wheels when the rear wheels roll.

[0006] In the cleaning base station of the present application, the cleaning base station further comprises a second spray head arranged on the base station main body, which is used for cleaning the front wheels when the front wheels roll.

[0007] In the cleaning base station of the present application, the cleaning module comprises two first support assemblies and two second support assemblies, the two first support assemblies are arranged at intervals along a second direction and are used for respectively supporting two rear wheels of the wheeled robot, and the two second support assemblies are arranged at intervals along the second direction and are used for respectively supporting two front wheels of the wheeled robot.

[0008] In the cleaning base station of the present application, the first support assembly further comprises a first support base. The first support base is detachably mounted on the base, and the unidirectional roller is arranged at an interval from the first roller on the first support base.

[0009] In the cleaning base station of the present application, the second support assembly comprises a second roller and a third roller, the second roller and the third roller are arranged at an interval along the first direction on the base, and the third roller is arranged on a side of the second roller away from the first support assembly; the second roller and the third roller are both used for supporting the front wheel.

[0010] In the cleaning base station of the present application, the second support assembly comprises a second support base, a second roller and a third roller. The second support base is detachably mounted on the base, the second roller and the third roller are arranged at an interval on the second support base, the third roller is arranged on a side of the second roller away from the first support assembly; the second roller and the third roller are both used for supporting the front wheel.

[0011] In the cleaning base station of the present application, the bottom of the base body is a reference surface. The distance from the top end of the unidirectional roller to the reference surface is a first distance L1, the distance from the top end of the first roller to the reference surface is a second distance L2, the distance from the top end of the second roller to the reference surface is a third distance L3, and the distance from the top end of the third roller to the reference surface is a fourth distance L4. Among them, the fourth distance L4 is greater than the third distance L3, the second distance L2 and the first distance L1.

[0012] In the cleaning base station of the present application, the third distance L3, the second distance L2 and the first distance L1 are the same.

[0013] In the cleaning base station of the present application, the outer periphery of the first roller, the second roller, the third roller and the unidirectional roller is wrapped with a buffer rubber layer.

[0014] In the cleaning base station of the present application, the first support assembly further comprises a unidirectional bearing and a first support bearing. The one-way roller is rotatably mounted on the first support via the one-way bearing, and the first roller is rotatably mounted on the first support via the first support bearing.

[0015] In the cleaning base station of this application, the first support component includes an oil seal, which is disposed at the connection between the one-way roller and the one-way bearing.

[0016] In the cleaning base station of this application, the second support assembly further includes a second support bearing and a third support bearing; The second roller is rotatably mounted on the second support via the second support bearing, and the third roller is rotatably mounted on the second support via the third support bearing.

[0017] In the cleaning base station of this application, the second support component includes a third support, which is mounted on the base; The third support is used to abut against the front wheel axle of the wheeled robot, so that the front wheel is suspended relative to the base.

[0018] In the cleaning base station of this application, the third support is provided with a limiting groove, which is used to engage with the front wheel axle of the wheeled robot.

[0019] In the cleaning base station of this application, a manifold is provided on the base, and the manifold is inclined along a first direction for collecting sewage generated during the cleaning of the wheeled robot.

[0020] Secondly, this application also provides a cleaning system, including the cleaning base station.

[0021] This application provides a cleaning base station, which has the following advantages: The cleaning base station of this application includes a base station body, a first support component, a second support component, and a first nozzle. When a wheeled robot enters the base station, the second support component supports the front wheel of the wheeled robot, or supports the front end of the wheeled robot, so that its front wheel is suspended relative to the base; the first support component supports the rear wheel of the wheeled robot. During cleaning, the rear wheel of the wheeled robot is driven to roll forward on the first support component. At this time, the first roller rotates under the rolling action of the rear wheel. The one-way roller is in a slipping state, rotating like an ordinary roller to adapt to the rolling of the rear wheel, thereby making the wheeled robot "slip in place" on the first support component and remain stationary relative to the base station body.

[0022] When the wheeled robot "slips in place" on the first support assembly, the first nozzle cleans the rolling rear wheels. Because the rear wheels are constantly rolling, the cleaning medium sprayed by the first nozzle can gradually clean the entire circumference of the rear wheels, thus achieving large-area cleaning and removing dirt, mud, grass clippings, and other debris from the rear wheel surface, improving the cleaning effect. When the wheeled robot completes cleaning and needs to exit the base station, it reverses. The unidirectional rollers, due to their unidirectional rotation characteristics, are in a clamped state and cannot rotate, preventing the wheeled robot from "slipping in place" and allowing it to exit the base station normally.

[0026] The specific embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but are not intended to limit the scope of this application.

[0028] In the description of this application, it should be understood that the terms "first," "second," etc., are used to describe various types of information, but these terms are not limited to them and are only used to distinguish information of the same type from one another. For example, without departing from the scope of this application, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

[0029] like Figures 1 to 5As shown, this application embodiment provides a cleaning base station 100, applied to a wheeled robot 200. The wheeled robot 200 includes a front wheel 202 and a rear wheel 201. The cleaning base station 100 includes a base station body 10, a first support component 20, a second support component 30, and a first nozzle 40. The first nozzle 40 is disposed on the base station body 10. The base station body 10 includes a base 11. The first support component 20 and the second support component 30 are spaced apart on the base 11 along a first direction X. The first support component 20 includes a first roller 21 and a one-way roller 22. The one-way roller 22 and the first roller... Wheels 21 are spaced apart on the base 11 along the first direction X, and one-way rollers 22 are located on the side of the first rollers 21 away from the second support assembly 30. Both the first rollers 21 and the one-way rollers 22 are used to support the rear wheels 201. When the rear wheels 201 move forward, the one-way rollers 22 are in a slipping state. When the rear wheels 201 move backward, the one-way rollers 22 are in a holding state. The second support assembly 30 is used to support the front wheels 202 or to support the front end of the wheeled robot 200 so that the front wheels 202 are suspended relative to the base 11. The first nozzle 40 is used to clean the rear wheels 201 when they are rolling.

[0030] It should be noted that the wheeled robot 200 is an intelligent robot that achieves positioning through the rolling of its front and rear wheels. The wheeled robot 200 may include lawnmower robots, cleaning robots, material handling robots, and inspection robots, etc., and the specific type of robot is not limited here.

[0031] In this embodiment, the base station body 10 is the main structure of the cleaning base station. The base station body 10 includes a base 11, which supports the wheeled robot 200, allowing the wheeled robot 200 to maintain a relatively stable position during the cleaning process. For ease of understanding, in this embodiment, a first direction X and a second direction Y, which are perpendicular to each other, are predefined and form a two-dimensional coordinate system. The wheeled robot 200 moves onto the base 11 along the first direction X, which is the forward-backward direction of the wheeled robot 200, and the second direction Y is the left-right direction of the wheeled robot 200.

[0032] Among them, the first roller 21 is a regular roller that can rotate in both directions, and the one-way roller 22 is a roller that can only rotate in one direction. When the rear wheel 201 (or the wheeled robot 200) moves forward, the one-way roller 22 is in a slipping state; when the rear wheel 201 moves backward, the one-way roller 22 is in a clamped state and cannot rotate.

[0033] Based on the above technical solution, when the wheeled robot 200 enters the base station, the second support component 30 supports the front wheel 202 of the wheeled robot 200, or supports the front end of the wheeled robot 200, so that its front wheel 202 is suspended relative to the base 11; the first support component 20 supports the rear wheel 201 of the wheeled robot 200. During cleaning, the rear wheel 201 of the wheeled robot 200 is driven to roll forward on the first support component 20. At this time, the first roller 21 rotates under the rolling action of the rear wheel 201, and the one-way roller 22 is in a slipping state. The one-way roller 22 rotates like an ordinary roller to adapt to the rolling of the rear wheel 201, so that the wheeled robot 200 "slips in place" on the first support component 20, and remains stationary relative to the base station body 10.

[0034] When the wheeled robot 200 "slips in place" on the first support component 20, the first nozzle 40 cleans the rolling rear wheel 201. Because the rear wheel 201 continues to roll, the cleaning medium sprayed by the first nozzle 40 can gradually clean the entire circumference of the rear wheel 201, thus achieving 360-degree wide-area cleaning and removing dirt, mud, grass clippings, and other debris from the surface of the rear wheel 201, improving the cleaning effect. When the wheeled robot 200 completes cleaning and needs to exit the base station, it reverses. At this time, the unidirectional roller 22, due to its unidirectional rotation characteristic, is in a clamped state and cannot rotate. The wheeled robot 200 will no longer "slip in place" when reversing, thus allowing it to exit the base station normally.

[0035] In this embodiment, the one-way roller 22 is installed on the side of the first roller 21 away from the second support component 30, and the one-way roller 22 is closer to the entrance of the base station than the first roller 21. Thus, when the wheeled robot 200 moves backward, both the rear wheel 201 and the front wheel 202 first abut against the first roller 21 and then against the one-way roller 22. Even if the first roller 21 can rotate, the one-way roller 22 holds it in place and stops rotating. When the wheel passes over the one-way roller 22, it is equivalent to climbing a slope, which generates friction and prevents slippage, thus allowing it to exit the base station.

[0036] In this embodiment, the position of the first nozzle 40 is not limited. The first nozzle 40 can be installed on the base 11 and spray the cleaning medium from bottom to top toward the rear wheel 201; or it can be installed on the side plate of the base station body 10 and spray the cleaning medium from the side of the wheeled robot 200 toward the rear wheel 201.

[0037] In some embodiments, such as Figure 4 As shown, the cleaning base station 100 also includes a second nozzle 50, which is disposed on the base station body 10 and is used to clean the front wheel 202 when the front wheel 202 is rolling.

[0038] Specifically, when the second support component 30 carries the front wheel 202 of the wheeled robot 200, or when the second support component 30 supports the front end of the wheeled robot 200 so that its front wheel 202 is suspended relative to the base 11, the front wheel 202 is driven to roll on the second support component 30 or above the base 11, and the cleaning medium is sprayed out through the second nozzle 50 to remove dirt, mud and grass debris from the surface of the front wheel 202, and to thoroughly clean the rolling front wheel 202, thereby improving the cleaning effect of the front wheel 202.

[0039] In this embodiment, the position of the second nozzle 50 is not limited. The second nozzle 50 can be installed on the base 11 and spray the cleaning medium from bottom to top toward the front wheel 202; or it can be installed on the side plate of the base station body 10 and spray the cleaning medium from the side of the wheeled robot 200 toward the front wheel 202.

[0040] In some embodiments, the wheeled robot 200 is a four-wheeled robot, such as... Figure 1 and Figure 2 As shown, the wheeled robot 200 has two front wheels 202 and two rear wheels 201. The cleaning module includes two first support components 20 and two second support components 30. The two first support components 20 are spaced apart along the second direction Y and are used to support the two rear wheels 201 of the wheeled robot 200 respectively. The two second support components 30 are spaced apart along the second direction Y and are used to support the two front wheels 202 of the wheeled robot 200 respectively.

[0041] Specifically, the four front and rear wheels of the wheeled robot 200 are supported by four support components, and the rear wheel 201 and the front wheel 202 are cleaned by the first nozzle 40 and the second nozzle 50, respectively. The cleaning process of each wheel does not affect each other, thus improving the wheel cleaning efficiency.

[0042] In some embodiments, the process of the first nozzle 40 cleaning the rear wheels 201 and the process of the second nozzle 50 cleaning the front wheels 202 can be performed simultaneously or asynchronously. Specifically, the cleaning processes of the two rear wheels 201 can be performed simultaneously or asynchronously; the cleaning processes of the two front wheels 202 can be performed simultaneously or asynchronously.

[0043] In some embodiments, such as Figures 5 to 7 As shown, the first support assembly 20 also includes a first support 23; the first support 23 is detachably mounted on the base 11, and the one-way roller 22 and the first roller 21 are spaced apart on the first support 23.

[0044] Specifically, the first support 23 is provided with slots for mounting the one-way roller 22 and the first roller 21. The one-way roller 22 and the first roller 21 are rolled on the first support 23 along the first direction X. The one-way roller 22 is mounted at the end of the first roller 21 away from the second support assembly 30, and the one-way roller 22 is closer to the entrance of the base station than the first roller 21. The one-way roller 22 and the first roller 21 can roll on the first support 23. The first support 23 can be mounted on the base 11 by means of bolt connection, snap connection, or pin fixation, so that the first support assembly 20 can be detachably mounted on the base 11.

[0045] For example, a first threaded hole is provided on the first support 23 and a second threaded hole is provided on the base 11. The positions of the first threaded hole and the second threaded hole correspond. The first support 23 is installed on the base 11 by bolts fastening it in the first threaded hole and the second threaded hole.

[0046] Because the first support assembly 20 is detachable, when a roller malfunctions or wears out and needs repair or replacement, the first support assembly 20 can be removed from the base 11 without the need for a complex disassembly of the entire cleaning base station, saving maintenance time and labor costs. For example, if the unidirectional roller 22 or the first roller 21 becomes stuck or damaged, simply unscrew the bolts securing the first support assembly 20, remove the first support assembly 20, replace it, and then reinstall it onto the base 11.

[0047] In some embodiments, such as Figure 5 As shown, the second support assembly 30 includes a second roller 31 and a third roller 32. The second roller 31 and the third roller 32 are spaced apart on the base 11 along the first direction X. The third roller 32 is located on the side of the second roller 31 away from the first support assembly 20. Both the second roller 31 and the third roller 32 are used to support the front wheel 202.

[0048] Specifically, the one-way roller 22, the first roller 21, the second roller 31, and the third roller 32 are arranged sequentially in the first direction X. The one-way roller 22 is a roller that can only rotate in one direction, while the first roller 21, the second roller 31, and the third roller 32 are all ordinary rollers that can rotate in both directions. In this embodiment, the base 11 has slots for mounting the second roller 31 and the third roller 32, which are tumblingly mounted on the base 11.

[0049] During cleaning, the front wheel 202 of the wheeled robot 200 rolls on the second support assembly 30. The second roller 31 and the third roller 32 rotate with the front wheel 202 to adapt to the movement of the front wheel 202. At this time, the front wheel 202 is in a "slipping in place" state. The cleaning medium is sprayed onto the front wheel 202 through the second nozzle 50 to perform a large-scale comprehensive cleaning of the rolling front wheel 202.

[0050] In some embodiments, such as Figure 5 , Figure 8 and Figure 9 As shown, the second support assembly 30 includes a second support 33, a second roller 31, and a third roller 32; the second support 33 is detachably mounted on the base 11, the second roller 31 and the third roller 32 are spaced apart on the second support 33, and the third roller 32 is located on the side of the second roller 31 away from the first support assembly 20; both the second roller 31 and the third roller 32 are used to support the front wheel 202.

[0051] Specifically, the second support 33 has slots for mounting the second roller 31 and the third roller 32. The second roller 31 and the third roller 32 are rolled on the second support 33 along the first direction X. The third roller 32 is located on the side of the second roller 31 away from the first support assembly 20, and the second roller 31 is closer to the first roller 21 than the third roller 32. The second roller 31 and the third roller 32 can roll bidirectionally on the first support 23. The second support 33 can be mounted on the base 11 by means of bolt connection, snap connection, or pin fixation, thereby allowing the second support assembly 30 to be detachably mounted on the base 11.

[0052] For example, a third threaded hole is provided on the second support 33 and a fourth threaded hole is provided on the base 11. The third threaded hole and the fourth threaded hole are positioned correspondingly. The second support 33 is installed on the base 11 by bolts fastening it into the third threaded hole and the fourth threaded hole.

[0053] Because the second support assembly 30 is detachable, when a roller malfunctions or wears out and needs repair or replacement, the second support assembly 30 can be removed from the base 11 without the need for a complex disassembly of the entire cleaning base station, saving maintenance time and labor costs. For example, if the second roller 31 or the third roller 32 becomes stuck or damaged, simply unscrew the bolts securing the second support assembly 30, remove the second support assembly 30, replace it, and then reinstall it on the base 11.

[0054] In practical applications, different models of wheeled robots 200 have different wheelbases, meaning the distance between the centers of the front and rear wheels varies. The holes on the base 11 corresponding to different wheelbases provide multiple mounting positions for the two support components. When it's necessary to accommodate robots with different wheelbases, simply remove the first support component 20 and the second support component 30 from their current holes, and then reinstall them into the corresponding holes according to the robot's wheelbase dimensions. This way, the distance between the first support component 20 and the second support component 30 matches the wheelbase of the lawnmower robot, ensuring that the wheeled robot 200 can be accurately and stably parked within the base station for cleaning.

[0055] In some embodiments, such as Figure 5 As shown, the bottom of the base station body 10 is the reference surface; the distance from the top of the unidirectional roller 22 to the reference surface is the first distance L1; the distance from the top of the first roller 21 to the reference surface is the second distance L2; the distance from the top of the second roller 31 to the reference surface is the third distance L3; the distance from the top of the third roller 32 to the reference surface is the fourth distance L4; wherein, the fourth distance L4 is greater than the third distance L3, the second distance L2 and the first distance L1.

[0056] Specifically, taking the bottom of the base station body 10 as the reference plane, the height formed relative to the reference plane is the relative height. Since the fourth distance L4 is greater than the third distance L3, the second distance L2 and the first distance L1, the relative height of the third roller 32 is the largest and higher than the other three rollers. This can block the front wheel 202 of the wheeled robot 200 and prevent the wheeled robot 200 from rushing past the third roller 32 at a relatively fast speed due to inertia when it reaches the position of the third roller 32. On the other hand, it can also prevent the wheeled robot 200 from continuing to move forward due to the continuous rolling of the front wheel 202 during the cleaning process. The third roller 32 can stably stop the wheeled robot 200 in the cleaning position and keep it "slipping in place" on the base 11.

[0057] In some embodiments, such as Figure 5 As shown, the third distance L3, the second distance L2, and the first distance L1 are the same. The relative heights of the first roller 21, the one-way roller 22, and the second roller 31 are the same and all are lower than the relative height of the third roller 32. With this setting, the upper surfaces of the first roller 21, the one-way roller 22, and the second roller 31 are flush, forming a flat support point. Because the height of each support point is consistent, there is no sudden change in height during the contact between the front wheel 202 and the above three rollers, avoiding the problem of bumps and jamming caused by height differences. The front wheel 202 can pass through the first support component 20 more smoothly, improving the passability of the front wheel 202.

[0058] In some embodiments, such as Figure 7 and Figure 9As shown, the outer periphery of the first roller 21, the second roller 31, the third roller 32 and the one-way roller 22 are all covered with a buffer rubber layer 60.

[0059] Specifically, the buffer layer 60 can be made of materials such as polyurethane, rubber, silicone, and foamed polyethylene. The buffer layer 60 has a high coefficient of friction. Each roller is covered with a layer of buffer layer 60. When the wheel contacts the roller, friction is generated between the surface of the buffer layer and the wheel, limiting lateral sliding or displacement during the robot's cleaning process and ensuring positioning accuracy. On the other hand, utilizing the elastic deformation capability of the buffer layer, mechanical vibration generated by the robot body is reduced when the robot enters or exits the base station or when the wheels run over the rollers. Furthermore, the buffer layer 60, made of the aforementioned wear-resistant materials, can withstand the rolling friction of the wheels, reducing wear on the roller body and extending the service life of the rollers.

[0060] In some embodiments, such as Figure 7 As shown, the first support assembly 20 also includes a one-way bearing 24 and a first support bearing 25; the one-way roller 22 is rotatably mounted on the first support 23 via the one-way bearing 24, and the first roller 21 is rotatably mounted on the first support 23 via the first support bearing 25.

[0061] It should be understood that the one-way bearing 24 can rotate freely in one direction of rotation, while it can be locked in the opposite direction of rotation to prevent reverse rotation. The one-way bearing 24 has internal structures such as rollers or wedges. When the inner ring of the bearing rotates relative to the outer ring in one direction, the rollers or wedges are in a free position, and the bearing can rotate smoothly; when rotating in the opposite direction, the rollers or wedges are wedged between the inner and outer rings, preventing relative rotation, and thus it is in a locked state.

[0062] In this embodiment, two one-way bearings 24 are installed at intervals along the second direction Y in two shaft holes of the first support 23. The inner rings of the two one-way bearings 24 are respectively sleeved at both ends of the one-way roller 22. The inner ring of the one-way bearing 24 can rotate unidirectionally relative to its outer ring in one direction, thereby realizing the one-way rolling of the one-way roller 22 on the first support 23.

[0063] Two first support bearings 25 are installed at intervals along the second direction Y in two shaft holes of the first support 23. The two ends of the first roller 21 are respectively fitted into the inner rings of the two first support bearings 25. The inner rings of the first support bearings 25 can rotate in both directions relative to their outer rings, thereby realizing the bidirectional rolling of the first roller 21 on the first support 23.

[0064] In some embodiments, such as Figure 7 As shown, the first support assembly 20 includes an oil seal 26, which is located at the connection between the one-way roller 22 and the one-way bearing 24.

[0065] Specifically, since the one-way bearing 24 does not have its own seal, in order to prevent the one-way bearing 24 from coming into contact with the cleaning medium during the wheel cleaning process, oil seals 26 are installed at the connection points between the one-way roller 22 and the one-way bearing 24 at both ends. This prevents the cleaning medium from seeping into the bearing and isolates the cleaning medium from contacting the metal parts such as the needle rollers and cage inside the one-way bearing 24. This avoids bearing corrosion, grease failure, or rotational jamming due to water corrosion and extends the service life of the one-way bearing 24.

[0066] In some embodiments, such as Figure 9 As shown, the second support assembly 30 also includes a second support bearing 34 and a third support bearing 35; the second roller 31 is rotatably mounted on the second support 33 via the second support bearing 34, and the third roller 32 is rotatably mounted on the second support 33 via the third support bearing 35.

[0067] Specifically, two second support bearings 34 are installed at intervals along the second direction Y in two shaft holes of the second support 33. The two ends of the second roller 31 are respectively fitted into the inner rings of the two second support bearings 34. The inner rings of the second support bearings 34 can rotate bidirectionally relative to their outer rings, thereby realizing the bidirectional rolling of the second roller 31 on the second support 33.

[0068] Two third support bearings 35 are installed at intervals along the second direction Y in two shaft holes of the second support 33. The two ends of the third roller 32 are respectively fitted into the inner rings of the two third support bearings 35. The inner rings of the third support bearings 35 can rotate bidirectionally relative to their outer rings, thereby realizing the bidirectional rolling of the third roller 32 on the second support 33.

[0069] In some embodiments, such as Figures 10 to 12 As shown, the second support component 30 includes a third support 36, which is mounted on the base 11. The third support 36 is used to abut against the axle 203 of the front wheel 202 of the wheeled robot 200 so that the front wheel 202 is suspended relative to the base 11.

[0070] Unlike the roller contact scheme described above, this embodiment adopts an overhead design, where the front wheel 202 is suspended relative to the base 11 when it is located on the third support 36. Figure 10 As shown, after the front wheel 202 of the wheeled robot 200 passes the position of the first support component 20, there is still a distance between the front wheel 202 and the third support 36; Figure 11 As shown, the wheeled robot 200 continues to move forward until the axle 203 of the front wheel 202 contacts the third support 36, at which point the tread of the front wheel 202 separates from the base 11; Figure 12As shown, as the rear wheel 201 continues to advance, the tread of the front wheel 202 is completely off the ground. At this time, the rear wheel 201 is located on the first support assembly 20 (not shown in the figure), which drives the front wheel 202 to roll above the base 11. The cleaning medium is sprayed out through the second nozzle 50 to remove dirt, mud, grass and other debris from the surface of the front wheel 202, and to thoroughly clean the rolling front wheel 202, thereby improving the cleaning effect of the front wheel 202.

[0071] In this embodiment, the front wheel 202 is suspended by the third support 36, allowing it to roll and be cleaned while suspended. This eliminates the need for roller support and still achieves thorough cleaning of the front wheel 202, improving both the cleaning effect and efficiency. Compared to the roller support solution, which requires at least two rollers, four bearings, and matching bushings, the suspended solution in this embodiment only requires one third support 36. Therefore, eliminating the roller support reduces production costs.

[0072] In some embodiments, such as Figures 10 to 12 As shown, the third support 36 is provided with a limiting groove 37, which is used to engage with the axle 203 of the front wheel 202 of the wheeled robot 200.

[0073] Specifically, after the axle 203 of the front wheel 202 contacts the third support 36, the axle 203 engages in the limiting groove 37 of the third support 36, at which point the tread of the front wheel 202 is completely off the ground. The limiting groove 37 limits the axle 203, which not only enhances the connection stability between the limiting groove 37 and the axle 203, but also prevents the axle 203 from rolling, thus preventing the robot from continuing to move forward.

[0074] In some embodiments, such as Figure 4 As shown, a collection channel 12 is provided on the base 11. The collection channel 12 is inclined along the first direction X and is used to collect the sewage generated when cleaning the wheeled robot 200.

[0075] Specifically, the manifold 12 can gradually tilt downwards along the direction from the first support component 20 to the second support component 30, or it can gradually tilt downwards along the direction from the second support component 30 to the first support component 20. By utilizing the slope formed by the inclined structure, the sewage on the base 11 during the cleaning process can be collected along the manifold 12 and discharged outside the base station, thus preventing sewage from accumulating inside the base station.

[0076] In some embodiments, the lowest point of the manifold 12 is also provided with a collection port (not shown in the figure) for collecting sewage and discharging it in a unified manner to avoid polluting the environment.

[0077] Secondly, embodiments of this application also provide a cleaning system, including a cleaning base station.

[0078] Specifically, since the cleaning system includes the aforementioned cleaning base station, it has all the beneficial effects of the cleaning base station, which will not be elaborated here.

[0079] In some embodiments, the cleaning system further includes a control module, a power supply module, and a water tank module. The water tank module stores cleaning water and supplies it to the cleaning base station via water pipes. The power supply module supplies power to the equipment in the cleaning base station. The control module enables remote control of the electronic equipment within the cleaning base station. Of course, the cleaning system is not limited to the modules mentioned above and may include other modules. This embodiment does not impose specific limitations, and therefore, will not elaborate further.
