Description

Technical Field

[0001] This application belongs to the field of cleaning equipment, and more specifically, relates to a ramp, a cleaning base station, and a cleaning system. Background Technology

[0002] With technological advancements, cleaning systems such as robotic vacuum cleaners, robotic mops, and sweeping-mopping robots are becoming increasingly widespread. Cleaning base stations, as supporting equipment for these cleaning systems, provide maintenance and enhance their automation. When the cleaning system completes its cleaning tasks or requires maintenance, it needs to return to the base station.

[0003] In related technologies, the ramps used to guide the cleaning host back to its position in the cleaning base station have the problem of taking up a large area, which affects the overall aesthetics of the equipment.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0005] This application aims to solve or improve the technical problem of large floor space occupied by ramp slabs in the prior art.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0007] In a first aspect, this application provides a ramp for installation on a base station body. The ramp has a walking area, and when a cleaning host walks along the extension direction of the walking area to enter or leave the base station body, the cleaning host comes into contact with the walking area.

[0008] Wherein, in the height direction of the ramp, at least a portion of the projected outer contour of the end of the ramp facing away from the base station body is always within the projection range of the cleaning host that is in contact with the walking area.

[0009] In one feasible implementation, the walking area includes:

[0010] The first walking area is used to raise the height of the cleaning host as it enters the base station body;

[0011] The second walking area is used to adjust the tilt angle of the cleaning host located on the ramp plate;

[0012] The number of first walking areas is two, and the two first walking areas are arranged at intervals along the width direction of the ramp slab. The second walking area is located between the two first walking areas and the maximum height of the second walking area does not exceed the maximum height of the first walking area.

[0013] In one feasible implementation, the first walking area includes a first lifting section and a first supporting section arranged sequentially along the extension direction of the walking area;

[0014] The end of the first lifting section that connects to the first supporting section is called the first end, and the end of the first lifting section that faces away from the first supporting section is called the second end. The first end and the second end are connected by a smooth curved surface, and the height of the first end is higher than the height of the second end.

[0015] In one feasible implementation, the junction between the first lifting section and the first supporting section is smoothly transitioned.

[0016] In one feasible implementation, the second walking area includes a second lifting section and a second supporting section arranged sequentially along the extending direction of the walking area;

[0017] The end of the second lifting section that connects to the second supporting section is the third end, and the end of the second lifting section that faces away from the second supporting section is the fourth end. The third end and the fourth end are connected by a smooth curved surface, and the height of the third end is higher than the height of the fourth end.

[0018] In one possible implementation, the junction between the second lifting section and the second supporting section is smoothly transitioned.

[0019] In one feasible implementation, a guide wheel is provided on the walking area, and the guide wheel is located between the first walking area and the second walking area;

[0020] The guide wheel protrudes relative to the first walking area.

[0021] In one feasible implementation, the guide wheel is rotatable about its own axis relative to the walking area, and the direction of rotation of the guide wheel is consistent with the extension direction of the walking area.

[0022] In one feasible implementation, the walking area is provided with a protruding edge, which is located between the first walking area and the second walking area, and the protruding edge protrudes relative to the first walking area.

[0023] In one feasible implementation, the ratio of the length to the width of the ramp slab is 0.45 to 0.55.

[0024] In a second aspect, this application provides a cleaning base station for maintaining a cleaning host. The cleaning base station includes a ramp and a base station body. The base station body has a receiving cavity for accommodating the cleaning host. The receiving cavity has an opening, and the ramp is disposed at the opening and connected to the base station body.

[0025] In one feasible implementation, the base station body includes a base for supporting the cleaning host, and the accommodating cavity is disposed above the base;

[0026] The ramp plate is detachably connected to the end of the base facing the opening.

[0027] In a third aspect, this application provides a cleaning system, including a cleaning base station and a cleaning host, wherein the cleaning host includes a walking wheel and a swivel wheel, and when the cleaning host is located in the accommodating cavity, both the walking wheel and the swivel wheel are in contact with the walking area.

[0028] Compared with the prior art, this application includes at least the following beneficial effects:

[0029] The ramp provided in this application embodiment can be adjusted in shape and size so that when the cleaning host stops on the ramp in the walking area, the end of the ramp facing away from the base station body can always be located below the cleaning host and blocked by the cleaning host. This achieves the effect of reducing the footprint of the ramp without affecting its normal function, which helps to improve the aesthetics of the relevant cleaning equipment. In addition, the ramp can also improve the processing cost, packaging and transportation cost of the ramp to a certain extent.

[0030] The cleaning base station and cleaning system provided in this application embodiment include the aforementioned ramp plate. Therefore, the cleaning base station and cleaning system incorporate at least one or more of the beneficial effects of the aforementioned ramp plates, which will not be elaborated further here. On the other hand, the cleaning base station and cleaning system with this ramp plate have a more compact and simpler structure, better spatial adaptability, and can be applied to installation environments of different sizes, thus improving adaptability to the installation environment.

[0059] This application provides a ramp 10, a cleaning base station 100, and a cleaning system 1000. The ramp and the base station body cooperate to form a cleaning base station, and the cleaning base station 100 and the cleaning host 200 cooperate to form the cleaning system 1000. The cleaning system 1000 includes the cleaning base station 100 with the ramp 10, and also includes a cleaning host 200 with a roller brush and / or mop. The cleaning system 1000 can be a mopping robot, a sweeping robot, or a floor scrubber with a base station and capable of mopping. The corresponding cleaning host 200 can be a mopping robot host, a sweeping robot host, or a floor scrubber host, etc., and the cleaning host 200 has sweeping and / or mopping functions. It is understood that, in addition to the roller brush and / or mop, the cleaning host 200 also includes wheels 201 and casters 202 for the movement of the cleaning host 200, in particular, the cleaning host 200 climbing relative to the ramp 10 back into the cleaning base station 100, or falling relative to the ramp 10 to leave the cleaning base station 100, etc.

[0060] The cleaning host 200 can be a device that automatically performs cleaning operations in a certain area to be cleaned. The cleaning base station 100 is used to maintain the cleaning host 200, such as washing the mop on the cleaning host 200, charging the cleaning host 200, replenishing water, and collecting dust. When the cleaning host 200 starts working, it can start from the cleaning base station 100 and execute the corresponding cleaning task; when the cleaning host 200 completes the cleaning task or other situations require the cleaning task to be stopped, the cleaning host 200 can return to the cleaning base station 100 to perform at least one or more of the following tasks: charging, replenishing water, washing, and collecting dust.

[0061] The cleaning base station 100 includes a base station body 20 and a ramp 10. The base station body 20 can be used to provide maintenance for the cleaning host 200. The ramp 10 serves as a transition and support when the cleaning host 200 is mounted on the pile (returning to the base station body 20), enabling the cleaning host 200 to smoothly, stably, and reliably mount the pile, reducing mounting resistance and improving the success rate of mounting. In addition, the ramp 10 can also guide the cleaning host 200 to smoothly and stably descend from the pile (away from the base station body 20) and perform corresponding cleaning operations. The base station body 20 can provide one or more maintenance functions for the cleaning host 200, such as cleaning, charging, water replenishment, and dust collection.

Figure 2 .

[0064] Please see Figure 1 and Figure 2 This application provides a ramp 10, which is a plate-like structure with a certain thickness, including a bottom surface 14 and a top surface arranged opposite each other. The height / thickness of the ramp 10 increases along the direction close to the base station body 20. At this time, the top surface is inclined relative to the bottom surface 14 to form a slope structure. The top surface of the ramp 10 is a slope structure, which can play a certain transition role in the process of the cleaning host 200 returning to the cleaning base station 100, thereby reducing the difficulty of the cleaning host 200 in pile driving, reducing pile driving resistance, and improving the success rate of pile driving.

[0065] Specifically, the top surface of the ramp 10 is provided with a walking area 11 for the cleaning host 200 to move around.

[0066] The cleaning unit 200 can move along the extension direction of the walking area 11 on the ramp 10. Since the ramp 10 is used for installation on the base station body 20, one end of the walking area 11 points towards the base station body 20, and the other end faces away from the base station body 20. During the movement of the cleaning unit 200 along the extension direction of the walking area 11 on the ramp 10, it can enter or leave relative to the base station body 20, thereby guiding the cleaning unit 200 to smoothly enter or exit the pile.

[0067] Please see Figures 1-3 In addition to the bottom surface 14 and the top surface mentioned above, the ramp 10 also includes two side surfaces at both ends in the width direction and two end surfaces at both ends in the extension direction, wherein the end surface used to connect with the base station body 20 is the connecting surface 15, and the end surface facing away from the base station body 20 is the front end.

[0068] The structure of the aforementioned walking area 11 is explained in detail below:

[0069] Specifically, the aforementioned walking area 11 includes a first walking area 111 and a second walking area 112. There are two first walking areas 111, spaced apart along the width of the ramp slab 10. The second walking area 112 is located between the two first walking areas 111. Please refer to [link / reference]. Figure 3The maximum height of the first walking area 111 is not lower than the maximum height of the second walking area 112, and the high point of the first walking area 111 is located between the high point of the second walking area 112 and the high point of the ramp 10. Therefore, the first walking area 111 can be used to raise the height of the cleaning host 200 during the process of the cleaning host 200 entering the base station body 20. Correspondingly, the second walking area 112 is used to adjust the tilt angle of the cleaning host 200 located on the ramp 10.

[0070] Please see Figure 4 The cleaning host 200 includes two traveling wheels 201 and two omnidirectional wheels 202. When the cleaning host 200 is mounted on a stake, its direction is adjusted so that the traveling wheels 201 are in front of the travel path and the omnidirectional wheels 202 are behind the travel path. Two first traveling zones 111 correspond to the travel paths of the two traveling wheels 201. During the mounting process, the two spaced-apart first traveling zones 111 support the two traveling wheels 201 located on the cleaning host 200. The traveling wheels 201 travel along the extension direction of the first traveling zones 111, driving the cleaning host 200 into the base station body 20. Since the first traveling zones 111 extend along the inclined direction of the ramp 10, the height of the cleaning host 200 can be increased during its movement, thereby reducing the difficulty of mounting the cleaning host 200 on the stake.

[0071] It should be noted that a preset interval, including the second travel area 112, is defined between the two oppositely arranged first travel areas 111. The size of this preset interval is not less than the axial length of the cleaning roller brush provided on the cleaning host 200, so as to allow the roller brush of the cleaning host 200 to pass through.

[0072] The aforementioned preset interval design not only helps reduce the material used in the ramp 10 and saves on the processing cost of the ramp 10, but also enables the brush to be avoided, helping to prevent friction between the brush and the ramp 10 from affecting the normal movement of the cleaning host 200 on the ramp 10.

[0073] Please see Figure 4 (Only a portion of the structure of the cleaning unit 200 in the figure is shown.) As the walking wheels 201 move forward, the omnidirectional wheels 202 move synchronously and, in this process, move from the ground onto the ramp 10 and come into contact with the second walking area 112. Since the second walking area 112 has a certain height relative to the ground on which the ramp 10 is installed, the tilt angle of the cleaning unit changes during this process, thereby enabling better coordination with the base station host.

[0074] It should be noted that the cleaning host 200 located above the ramp 10 can always be in contact with the walking area 11. For example, when the cleaning host 200 moves along the extension direction of the walking area 11 to enter or leave relative to the base station body 20, the walking wheels 201 in the cleaning host 200 can always remain in contact with the first walking area 111, and correspondingly, the casters 202 can remain in contact with the second walking area 112 when the cleaning host 200 cooperates with the cleaning base station 100.

[0075] Please see Figure 4 and Figure 5 In the height direction of the ramp 10, at least a portion of the projected outer contour of the end of the ramp 10 facing away from the base station body 20 is always within the projection range of the cleaning host 200 that is in contact with the walking area 11.

[0076] When the cleaning host 200 and the cleaning base station 100 are in a cooperative state, the projection of the cleaning host 200 in the height direction of the ramp 10 can cover at least a portion of the projected outer contour of the end of the ramp 10 facing away from the base station body 20 (which can be referred to as the front end of the ramp 10). The height direction Z is... Figure 4 The arrow direction is shown. Please refer to [link / reference]. Figure 5 From a top-down view, it can be seen that the front center of the ramp 10 is located below and obscured by the cleaning unit 200. Visually, the length of the ramp 10 appears shorter.

[0077] In other words, the ramp 10 provided in this embodiment can reduce the floor space occupied by the ramp 10 without affecting its normal function, which helps to improve the aesthetics of the relevant cleaning equipment. In addition, the ramp 10 can also improve the processing cost, packaging and transportation cost of the ramp 10 to a certain extent.

[0078] In some embodiments, the ratio of the length to the width of the ramp 10 can be set to 0.45 to 0.55, and the specific value can be adaptively adjusted within this range according to design needs.

[0079] Please see Figure 2 and Figure 5 In the figure, X represents the length of ramp 10, and Y represents the width of ramp 10.

[0080] When the width of the ramp 10 is 400mm, its length ranges from 180mm to 220mm. This specific value can be adaptively adjusted within this range according to design needs. For example, the length of the ramp 10 can be any value among 180mm, 185mm, 190mm, 195mm, 200mm, 205mm, 210mm, 215mm, and 220mm. As the width of the ramp 10 increases or decreases, its length will also increase or decrease accordingly. The width of the ramp 10 is affected by the dimensions of the cleaning host 200. Taking the cleaning host 200 as a columnar structure with a certain thickness as an example, the larger the diameter of the cleaning host 200, the larger the width of the ramp 10. Furthermore, the width of the ramp 10 should be slightly larger than the diameter of the cleaning host 200 to ensure that the ramp 10 can guide the cleaning host 200 into the base station body 20 that cooperates with the ramp 10.

[0081] In other embodiments, the length of the ramp slab 10 is related to its height; the higher the ramp slab 10, the longer its length. Specifically, the ratio of the height to the length of the ramp slab 10 can be set to 0.07 to 0.12. The specific value can be adaptively adjusted within this range according to design needs. For example, the ratio can be any value among 0.07, 0.08, 0.09, 0.10, 0.11, and 0.12.

[0082] Specifically, in this embodiment, the ratio of the height of the ramp 10 to the length of the ramp 10 can be set to 0.10.

[0083] When in use, the ramp 10 with the above-mentioned dimensional relationship has a better visual effect, especially when the cleaning host 200 is parked at the cleaning base station 100, the front end of the ramp 10 can be blocked by the cleaning host 200, thereby reducing the footprint of the ramp 10 and helping to improve the aesthetics of the related cleaning equipment.

[0084] The first walking area 111 for raising the height of the cleaning host 200 includes a first lifting section 1111 and a first supporting section 1112. The first supporting section 1112 and the first lifting section 1111 are arranged sequentially along the extension direction of the walking area 11. The height of the first lifting section 1111 increases along the extension direction of the walking area 11, which is the walking direction of the cleaning host 200 into the cleaning base station 100. The two ends of the first lifting section 1111 along the extension direction are a first end 1111a and a second end 1111b, which are connected by a smooth curved surface to form the first lifting section 1111. The height of the first end 1111a is higher than the height of the second end 1111b.

[0085] Please see Figure 1 The first end 1111a is connected to the first supporting section 1112, meaning that the first supporting section 1112 is located on the side of the first lifting section 1111 closer to the base station body 20. The first supporting section 1112 is a plane or a curved surface with a small curvature that is approximately plane. It can be seen that the plane where the first supporting section 1112 is located can remain parallel or approximately parallel to the plane where the bottom surface 14 is located.

[0086] As the wheels 201 of the cleaning unit 200 move forward along the first walking area 111, the cleaning unit 200 is gradually raised as the surface height of the first lifting section 1111 gradually increases; after the wheels 201 of the cleaning unit 200 enter the first supporting section 1112 along the first walking area 111, the height of the cleaning unit 200 remains basically unchanged.

[0087] Specifically, in the extension direction of the first lifting segment 1111, there may be multiple sub-lifting segments, each with a different curvature, to guide the cleaning host 200 to achieve a smooth and stable height increase, thereby improving the reliability of the cleaning host 200 on the pile.

[0088] In some embodiments, the first lifting segment 1111 may be configured to include three sequentially connected sub-lifting segments, wherein the curvature of the three sub-lifting segments gradually decreases along the extension direction of the first lifting segment 1111, and the curvature of the sub-lifting segment having the second end 1111b is greater than the curvature of the sub-lifting segment having the first end 1111a. This structural configuration enables rapid lifting of the cleaning unit 200 and buffering after lifting, avoiding the difficulty of mounting the cleaning unit 200 on piles caused by driving in a high curvature segment.

[0089] In other embodiments, a first lifting segment 1111 composed of three sub-lifting segments may be provided, wherein the middle sub-lifting segment is a straight segment composed of a plane.

[0090] In other similar embodiments, the first walking area 111 may also include a first climbing section 1113. Please refer to [link to relevant documentation]. Figure 1 The first climbing section 1113 is connected to the first lifting section 1111 via the second section. The end of the first climbing section 1113 facing away from the first lifting section 1111 is connected to the bottom surface 14 via the front end of the ramp 10.

[0091] The first climbing section 1113 is an inclined slope, which can be composed of inclined planes and / or curved surfaces. It can be used to guide the walking wheels 201 located on the ramp slab 10 to achieve initial climbing and lifting before traveling to the first lifting section 1111.

[0092] Specifically, the portion of the first climbing section 1113 near the first lifting section 1111 can be set as a plane that is parallel or approximately parallel to the bottom surface 14, while the remaining portion is a curved surface with a certain angle of inclination.

[0093] To further reduce the difficulty of mounting the cleaning unit 200 on piles, a smooth transition can be made at the joint between the first lifting section 1111 and the first supporting section 1112; similarly, a smooth transition can be made at the joint between the first lifting section 1111 and the first climbing section 1113. This structural design not only helps to improve the success rate of mounting the cleaning unit 200 on piles, but also improves the structural strength of the ramp slab 10 to a certain extent, avoiding damage caused by stress concentration at the joint.

[0094] In some embodiments, at least a portion of the surface of the first walking area 111 is provided with an anti-slip structure to reduce the probability of the cleaning host 200 slipping or sliding when it travels in the first walking area 111, thereby improving the success rate of the cleaning host 200 on the pile.

[0095] For details, please refer to Figure 1 and Figure 2 The aforementioned anti-slip structure includes a textured structure with anti-slip function that protrudes from the surface of the first walking area 111. For example, the anti-slip structure may be a plurality of anti-slip ribs that protrude from the surface of the first walking area 111 and are arranged in parallel, with the extending direction of the anti-slip ribs perpendicular to the extending direction of the first walking area 111; or, the anti-slip structure may be a granular protrusion or other structure that protrudes from the surface of the first walking area 111.

[0096] It should be noted that in actual use, the trajectory of the cleaning unit 200 during pile driving may deviate from the actual trajectory. Therefore, the dimension of the first traveling area 111 in the width direction of the ramp slab 10 needs to be slightly larger than the dimension of the traveling wheels 201 of the cleaning unit 200 to ensure that the traveling wheels 201 can travel along the extension direction of the first traveling area 111 during pile driving. Furthermore, the width of the first climbing section 1113 can be set to be greater than the width of the first lifting section 1111 and the first supporting section 1112. This design can provide some guidance for the cleaning unit 200, helping to reduce the possibility of slippage when the cleaning unit 200 contacts the ramp slab 10, and preventing the cleaning unit 200 from deviating from the correct path due to inertia or external forces when contacting and lifting along the ramp slab 10, thus preventing pile driving failure.

[0097] Please see Figures 1-3The second walking area 112, which is used to adjust the tilt angle of the cleaning host 200 located on the ramp 10, includes a second lifting section 1121 and a second supporting section 1122, wherein the second lifting section 1121 and the second supporting section 1122 are arranged sequentially along the extension direction of the walking area 11, and the height of the second lifting section 1121 increases along the extension direction of the walking area 11.

[0098] Along the length of the ramp slab 10, the length of the second lifting section 1121 is basically the same as the length of the first lifting section 1111, or the length of the second lifting section 1121 is slightly shorter than the length of the first lifting section 1111; the length of the second supporting section 1122 is basically the same as the length of the first supporting section 1112, or the length of the second supporting section 1122 is slightly shorter than the length of the first supporting section 1112.

[0099] The two ends of the second lifting segment 1121 along the extension direction are the third end 1121a and the fourth end 1121b, respectively. The third end 1121a and the fourth end 1121b are connected by a smooth curved surface and form the second lifting segment 1121. The height of the third end 1121a is higher than the height of the fourth end 1121b.

[0100] Please see Figures 1-3 The third end 1121a is connected to the second supporting section 1122, and the fourth end 1121b is connected to the bottom surface 14. That is, the second supporting section 1122 is located on the side of the second lifting section 1121 closest to the base station body 20. The second supporting section 1122 is a plane or a curved surface with a small curvature, approximately a plane. It can be seen that the plane containing the second supporting section 1122 can remain parallel or approximately parallel to the plane containing the bottom surface 14. In other words, the plane containing the second supporting section 1122 can remain parallel or approximately parallel to the plane containing the first supporting section 1112.

[0101] As the cleaning unit 200 travels along the walking area 11 until the caster 202 contacts the second walking area 112, the height of the caster 202 gradually increases as the surface height of the second lifting section 1121 rises. After the caster 202 travels along the second lifting section 1121 to the second supporting section 1122, its height remains essentially unchanged. During this process, as the height of the caster 202 increases, the tilt angle of the cleaning unit 200 relative to the mounting surface of the ramp 10 changes.

[0102] Please see Figure 4As can be seen, the overall height of the cleaning unit 200 is affected by the position of the traveling wheels 201. When the traveling wheels 201 move to the first support section 1112, the cleaning unit 200 is raised to its highest point. As the traveling wheels 201 continue to move, the casters 202 come into contact with the second lifting section 1121 and the second support section 1122 in the second traveling area 112 in sequence. During this process, the casters 202 are gradually raised, causing the tilt angle of the cleaning unit 200 relative to the bottom surface 14 of the ramp 10 to change and gradually decrease.

[0103] This process helps adjust the overall posture of the cleaning host 200 when it enters the cleaning base station 100, so that the cleaning host 200 can be adapted to the relevant functional modules in the cleaning base station 100, such as the charging module, cleaning module and dust collection module, to achieve the corresponding maintenance functions.

[0104] After the cleaning host 200 is installed on the pile, the included angle between the cleaning host 200 and the bottom surface 14 of the ramp 10 can be set as α: the plane on the end face of the cleaning host 200 facing away from the ramp 10 is defined as the first plane, and the plane on the bottom surface 14 of the ramp 10 is defined as the second plane. The included angle between the first plane and the second plane is α.

[0105] Specifically, the value of α ranges from 3 to 5°, and its specific value can be adaptively adjusted within this range according to design needs. For example, α can be any value from 3.0°, 3.1°, 3.2°, 3.3°, 3.4°, 3.5°, 3.6°, 3.7°, 3.8°, 3.9°, 4.0°, 4.1°, 4.2°, 4.3°, 4.4°, 4.5°, 4.6°, 4.7°, 4.8°, 4.9°, and 5°.

[0106] Specifically, multiple sub-lifting segments can also be provided in the extension direction of the second lifting segment 1121. By adjusting the curvature changes of each sub-lifting segment, the attitude of the cleaning host 200 entering the base station body 20 can be adjusted. The structure and connection method of each sub-lifting segment in the second lifting segment 1121 are basically the same as those of each sub-lifting segment in the first lifting segment 1111 described above, and can be referred to the description of the above embodiment, which will not be repeated here.

[0107] To reduce the climbing resistance of the caster wheel 202, a smooth transition can be made at the joint between the second lifting section 1121 and the second supporting section 1122.

[0108] Since there is a certain height difference between the first supporting section 1112 and the second supporting section 1122, in other similar embodiments, the second walking area 112 also includes a connecting section 1123. Please refer to [link to relevant documentation]. Figure 1 and Figure 3 The connecting section 1123 is located at the end of the second supporting section 1122 that faces away from the second lifting section 1121. The joint between the connecting section 1123 and the second supporting section 1122 is smoothly transitioned.

[0109] The end of connecting segment 1123 pointing towards connecting surface 15 can be raised to a surface that is horizontal or substantially horizontal with the first supporting segment 1112. (See also...) Figure 1 , Figure 4 and Figure 6 The plane of the end of the connecting section 1123 facing away from the second supporting section 1122 is basically the same plane as the plane of the first supporting section 1112 used to support the walking wheel 201.

[0110] In actual use, due to a certain error in the trajectory of the cleaning host 200 when it goes up to the pile, the walking trajectory of the cleaning host 200 deviates from the ideal route. The roller brush located below the cleaning host 200 directly contacts the first walking area 111, making it difficult for the cleaning host 200 to go up to the pile. To solve this problem, a raised edge 13 needs to be set on the walking area 11.

[0111] Please see Figure 1 and Figure 7 The aforementioned walking area 11 is also provided with a protruding edge 13, which is located between the first walking area 111 and the second walking area 112 and protrudes relative to the first walking area 111.

[0112] Specifically, the aforementioned protruding edge 13 is located at one end edge of the first traveling area 111 facing the second traveling area 112. Please refer to [link / reference]. Figure 2 Each of the two first walking zones 111 has a protruding edge 13 at one end facing the second walking zone 112. The protrusion is provided along the extension direction of the first walking zone 111 and protrudes in the direction away from the top surface of the ramp slab 10 (i.e., protrudes along the thickness direction of the ramp slab 10). When the cleaning host 200 travels along the extension direction of the ramp slab 10, the protruding edge 13 can be used to support the roller brush and other structures provided on the bottom surface 14 of the cleaning host 200, so as to prevent the roller brush from directly contacting the first walking zone 111, thereby affecting the smooth pile mounting of the cleaning host 200.

[0113] There is a height difference between the surface of the protruding edge 13 facing away from the top surface of the ramp 10 and the surface of the adjacent first walking area 111.

[0114] Specifically, the aforementioned height difference should not exceed 9mm. For example, the height difference may not be completely consistent at different locations along the extension direction of the first traveling zone 111. Please refer to [link / reference]. Figure 3In the first climbing section 1113, the height difference ranges from 0 to 9 mm and gradually increases; in the first lifting section 1111, the height difference ranges from 5 to 9 mm and gradually decreases; in the first supporting section 1112, the height difference ranges from 0 to 5 mm and gradually decreases. The above height difference data ranges are for illustrative purposes only.

[0115] It should be noted that when the surface of the first walking area 111 is provided with an anti-slip structure, the aforementioned protruding edge 13 should not be lower than the anti-slip structure, so as to prevent the roller brush and other components from rubbing against the anti-slip structure, thereby affecting the forward movement of the cleaning host 200 on the ramp 10.

[0116] The two opposing convex edges 13 can directly contact the roller brush and lift it up when the cleaning host 200 moves onto the ramp 10, avoiding contact between the roller brush and the surface of the first walking area 111, thus facilitating the mounting of the cleaning host 200.

[0117] Please see Figure 3 and Figure 4 The end of the aforementioned protruding edge 13 facing away from the top surface of the ramp plate 10 is a smooth curved surface.

[0118] Understandably, in order to further improve the uphill efficiency of the cleaning host 200, in some embodiments, guide wheels 12 may also be provided on the walking area 11. The guide wheels 12 are located on the side of the convex edge 13 facing away from the first walking area 111.

[0119] The guide wheel 12 is located between the first travel area 111 and the second travel area 112, and the guide wheel 12 protrudes relative to the first travel area 111. (See also...) Figure 1 and Figure 3 The walking area 11 is provided with two spaced guide wheels 12, which are located on both sides of the second walking area 112.

[0120] For details, please refer to Figure 3 and Figure 4 The aforementioned guide wheel 12 protrudes relative to the top surface of the ramp 10. In the width direction of the ramp 10, the guide wheel 12 is disposed adjacent to the first lifting section 1111 and the first supporting section 1112, and the end of the guide wheel 12 facing away from the top surface of the ramp 10 protrudes relative to the first walking area 111.

[0121] As the cleaning host 200 moves along the length of the ramp 10 toward the base station body 20, the guide wheel 12 can contact the side surface of the cleaning host 200 facing the ramp 10, providing additional support and balance assistance to the cleaning host 200. This helps to distribute the weight of the cleaning host 200, making the center of gravity of the cleaning host 200 more stable and reducing the risk of the cleaning host 200 failing to climb the ramp due to an unstable center of gravity.

[0122] In one feasible implementation, the guide wheel 12 is rotatable about its own axis relative to the walking area 11 and the direction of rotation of the guide wheel 12 is consistent with the extension direction of the walking area 11.

[0123] During the uphill process of the cleaning unit 200, the rotatable guide wheel 12 can reduce the friction between the main body of the cleaning unit 200 and the ramp 10 by rotating, thereby reducing the difficulty of the cleaning unit 200 climbing the slope. In addition, the guide wheel 12 can also guide the cleaning unit 200 to move in the preset direction of travel by rotating, preventing the cleaning unit 200 from deviating from the correct travel route, so that it can accurately reach the set point and improve the success rate of climbing the pile. In addition, the guide wheel 12 can also, to a certain extent, prevent foreign objects (such as hair, small solid particles, etc.) attached to the bottom of the main body of the cleaning unit 200 from entering the gap between the ramp 10 and the cleaning unit 200 as the cleaning unit 200 moves, thereby reducing the possibility of foreign objects getting stuck on the cleaning unit 200.

[0124] Please see Figure 1 and Figure 7 The ramp 10 is provided with a clearance groove 151 at the connection surface 15 for connecting with the base station body 20. After the ramp 10 is connected to the base station body 20 through the connection surface 15, the relevant modules provided on the base station body 20 can be embedded in the clearance groove 151.

[0125] Specifically, the base station body 20 may be configured to have a cleaning module that is at least partially located outside the base station body 20, and the cleaning module may be embedded in the clearance slot 151.

[0126] Please see Figure 7 The ramp 10 has a claw 152 on its connecting surface 15. The ramp 10 can be connected to the base station body 20 via the claw 152.

[0127] It is understood that the shape and size of the ramp 10 provided in this embodiment of the application have been adjusted. When it is assembled and applied to the base station body 20, it not only enables the cleaning host 200 to move normally relative to the base station body 20 and to move up and down the piles, but also reduces the floor space occupied by the ramp 10 during installation. When the cleaning host 200 is parked on the ramp 10, the middle part of the end of the ramp 10 facing away from the base station body 20 is always located below the cleaning host 200 and is blocked by the cleaning host 200. From the user's perspective, the floor space occupied by the ramp 10 can be significantly reduced, freeing up more usable space and helping to improve space utilization. In addition, the ramp 10 can also improve the processing cost, packaging, and transportation cost of the ramp 10 to a certain extent.

[0128] Figure 8This is a schematic diagram of the structure of the clean base station 100 provided in the embodiments of this application. Figure 9 This is a schematic diagram showing the connection between the base 23 and the ramp 10 in the clean base station 100 provided in this embodiment of the application. Figure 10 This is a schematic diagram showing the connection between the base 23 and the ramp 10 in the clean base station 100 provided in this embodiment of the application at another angle. Figure 11 This is a schematic diagram of the structure of the base 23 facing the ramp 10 in the clean base station 100 provided in this embodiment of the application. Figure 12 This is a schematic diagram showing the cooperation between the base 23 and the ramp 10 in the clean base station 100 provided in the embodiments of this application.

[0129] Please see Figure 8 and Figure 9 This application provides a cleaning base station 100 for maintaining the aforementioned cleaning host 200, including a base station body 20 and a ramp 10. The base station body 20 has a receiving cavity 21 for accommodating the cleaning host 200, the receiving cavity 21 having an opening 22, and the ramp 10 is disposed at the opening 22 and connected to the base station body 20. Figure 8 and Figure 9 Only a portion of the base station host structure is shown in the image.

[0130] In this clean base station 100, the specific structure of the ramp 10 can be the same as the structure of any embodiment of the ramp 10 described above, and will not be repeated here.

[0131] The base station body 20 includes a base 23 for supporting the cleaning host 200, and a receiving cavity 21 is located above the base 23. A ramp 10 is located on one side of the base 23, and the bottom surface 14 of the ramp 10 is parallel to the lower surface of the base 23 of the base station body 20. The cleaning host 200 can move along the walking area 11 on the top surface of the ramp 10 toward the opening 22 of the base station body 20, and finally stop in the receiving cavity 21 to complete the mounting; the cleaning host 200 can also move along the walking area 11 on the top surface of the ramp 10 toward a direction away from the base station body 20, until the cleaning host 200 leaves the ramp 10 to complete the lowering.

[0132] The ramp 10 can be integrally formed with the base 23, or it can be separately formed from the base 23.

[0133] Please see Figure 10 At this point, the ramp 10 and the base 23 are formed separately.

[0134] Specifically, the ramp 10 and the base 23 can be detachably connected at the end facing the opening 22, for example, by snap-fit ​​or bolt connection. In other embodiments, the ramp 10 and the base 23 can also be connected by means of gluing, riveting, or welding, and this embodiment does not limit this.

[0135] Taking the detachable connection between ramp 10 and base 23 via a snap-fit ​​mechanism as an example, the connection structure between ramp 10 and base 23 is explained as follows:

[0136] Please see Figure 7 The connecting surface 15 of the ramp slab 10 is provided with a claw 152; please refer to Figure 11 The base 23 has a positioning groove 231 and a buckle 232 on the side that is connected to the ramp 10. The positioning groove 231 is arranged sequentially along the width direction, and multiple buckles 232 are arranged at intervals on the side wall of the positioning groove 231.

[0137] When the ramp 10 is connected to the base 23, please refer to Figure 12 At this time, the aforementioned claw 152 extends into the positioning groove 231 and engages with the buckle 232 provided on the side wall of the positioning groove 231.

[0138] Specifically, the claw 152 can undergo elastic deformation under certain pressure. When the claw 152 is inserted into the positioning groove 231 and contacts the latch 232, under the pressure applied by the latch 232 and the outside, the claw 152 undergoes recoverable elastic deformation during insertion. After the claw 152 is inserted into place, its elastic deformation is restored, thus engaging with the latch 232 and firmly connecting with the base 23.

[0139] It is understood that the clean base station 100 provided in this application embodiment has the aforementioned ramp 10, therefore the clean base station 100 includes at least one or more of the beneficial effects of the aforementioned ramp 10, which will not be elaborated further here. On the other hand, the structure of the clean base station 100 with the ramp 10 can be improved to a certain extent, becoming more compact and simpler, achieving the goal of reducing the floor space occupied by the clean base station 100. In limited usage environments, this improvement can increase space utilization, making it suitable for smaller installation environments and improving the adaptability of the base station to installation space.

[0140] Figure 13 This is a schematic diagram of the structure of the cleaning system 1000 provided in an embodiment of this application. Figure 14 for Figure 13 A schematic diagram of the side structure. Figure 15 for Figure 14 Enlarged view of part of the structure.

[0141] Please see Figure 13 This application provides a cleaning system 1000, which includes a cleaning base station 100 and a cleaning host 200. The specific structure of the cleaning base station 100 can be the same as the structure of any embodiment of the cleaning base station 100 described above, and will not be repeated here.

[0142] The cleaning base station 100 has a base station body 20. The base station body 20 has a cavity 21 for accommodating the cleaning host 200. The cavity 21 has an opening 22. A ramp 10 is located at the opening 22 and connected to the base station body 20. The cleaning host 200 can enter the cavity 21 through the opening 22 via the ramp 10.

[0143] The cleaning unit 200 may be partially located inside the receiving cavity 21 and partially located outside the receiving cavity 21. Please refer to [link / reference]. Figure 13 It should be noted that the cleaning unit 200 includes wheels 201 and casters 202. When the cleaning unit 200 is located inside the receiving cavity 21, both wheels 201 and casters 202 are in contact with the walking area 11 of the ramp 10.

[0144] Specifically, the traveling wheel 201 contacts the first traveling area 111 of the ramp 10, and the swivel wheel 202 contacts the second traveling area 112 of the ramp 10. Please refer to [link / reference]. Figure 14 and Figure 15 .

[0145] In some embodiments, the base station body 20 of the clean base station 100, in addition to the base 23, also includes a housing. The housing is located above the base 23, and a receiving cavity 21 is formed between the base 23 and the housing.

[0146] Along the length of the ramp 10, the base station body 20 formed by the aforementioned shell and base 23 also has a certain length. Please refer to... Figure 14 The length of the base station body 20 is not less than the length of the ramp 10.

[0147] Specifically, the ratio of the length of the base station body 20 to the length of the ramp 10 is in the range of 1.01 to 1.10. The specific value can be adaptively adjusted within this range according to design needs. For example, the ratio can be any value among 1.01, 1.02, 1.03, 1.04, 1.05, 1.06, 1.07, 1.08, 1.09, 1.10, etc.

[0148] The cleaning system 1000 provided in this application embodiment includes the aforementioned cleaning base station 100. Therefore, the cleaning system 1000 incorporates at least one or more of the beneficial effects of the aforementioned cleaning base station 100, which will not be elaborated further here. Simultaneously, the installation footprint of the cleaning system 1000 is reduced, thus enabling it to be applied to more compact installation spaces. This effectively reduces the space requirements of the equipment, minimizes the visual impact of the cleaning system 1000 after installation, enhances the aesthetics of the equipment, improves the space utilization rate of the equipment, and frees up more usable space for users during actual use.

[0149] The description of the various embodiments above tends to emphasize the differences between the various embodiments. The similarities or similarities between them can be referred to, and for the sake of brevity, they will not be repeated here.

[0150] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
