Technical Field

[0001] The utility model relates to the technical field of base stations, and in particular to a bearing mechanism of a base station, a base station and a cleaning system. Background Art

[0002] When the cleaning robot enters the base station to collect dust, it generally docks with the dust collection port of the base station through the dust outlet at the bottom. However, in the process of entering the base station, the bottom of the cleaning robot is likely to scratch the dust collection port, which may cause the cleaning robot to be lifted up and unable to smoothly fall into place, and the dust collection port to be worn. This increases the resistance of the cleaning robot to the base station and accelerates the wear of the docking between the two dust ports, resulting in poor airtightness, which makes the dust collection fail and garbage leak.

[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0039] It should also be understood that the terms used in the utility model specification are only for the purpose of describing specific embodiments and are not intended to limit the utility model. As used in the utility model specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0040] It should be further understood that the term “and / or” used in the present specification and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0041] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0042] See also Figure 1 The embodiment of the utility model provides a base station 10, which can maintain the cleaning robot 20. For example, after the cleaning robot 20 moves to the preset docking position and completes the alignment, the base station 10 can be used to provide at least one of the following maintenance for the cleaning robot 20: charging, dust collection, mop cleaning, water replenishment, sewage extraction, etc.

[0043] See also Figure 2 In some embodiments, the cleaning robot 20 includes a driving wheel 202, which can provide driving force for the cleaning robot 20 to ensure that the cleaning robot 20 can walk. Exemplarily, in order to enable the cleaning robot 20 to have a certain obstacle-crossing capability, the driving wheel 202 is provided with tire teeth to increase the surface roughness of the driving wheel 202.

[0044] See also Figure 1 In some embodiments, the base station 10 includes a supporting mechanism 11, the supporting mechanism 11 includes a supporting seat 111, a dust collecting portion 112 and a protruding portion 113, the supporting seat 111 is used to support the cleaning robot 20; the dust collecting portion 112 is arranged on the supporting seat 111, and the dust collecting portion 112 is used to communicate with the dust outlet 201 of the cleaning robot 20; the protruding portion 113 is arranged on the tire groove of the supporting seat 111, and the protruding portion 113 increases the deformation of the driving wheel 202 by engaging with the driving wheel 202 of the cleaning robot 20 to enhance the traction of the cleaning robot 20 into the base station 10. It is understandable that the engagement between the protrusion 113 and the driving wheel 202 includes but is not limited to: the protrusion 113 can contact the ground surface 2022 of the driving wheel 202 and apply pressure to the ground surface 2022 during the movement of the driving wheel 202 to achieve the deformation of the driving wheel 202; the protrusion 113 can contact the bite groove 2021 of the driving wheel and bite the bite groove 2021 during the movement of the driving wheel 202 to achieve the deformation of the driving wheel 202. The tire groove is the corresponding stop position of the driving wheel 202 after the cleaning robot 20 enters the preset docking position of the base station 10, and the tire groove can be a groove shape, which is compatible with the shape of the driving wheel 202.

[0045] In some embodiments, the base station 10 further includes a base station body (not shown) connected to the supporting mechanism 11, and various functional components are arranged in the base station body, such as: a clean water tank, a sewage tank, a dust collection container, a water pipe, etc.

[0046] See also Figure 1 and Figure 5 In some embodiments, the dust collecting unit 112 includes a dust collecting port 1121 and a dust collecting channel (not shown in the figure), the dust collecting port 1121 is connected to the dust outlet port 201 of the cleaning robot 20, and the dust collecting channel is connected to the dust collecting port 1121 and the dust collecting container of the base station 10 respectively. When the cleaning robot 20 performs a dust collection operation on the base station 10, the garbage in its dust box is sucked into the dust collecting container through the dust outlet port 201, the dust collecting port 1121, and the dust collecting channel in turn.

[0047] The supporting mechanism 11 of the above-mentioned embodiment has a reasonable structural design. The raised portion 113 of the supporting mechanism 11 increases the deformation of the driving wheel 202 by engaging with the driving wheel 202 of the cleaning robot 20 to improve the traction force of the cleaning robot 20 entering the base station 10. Therefore, during the process of the cleaning robot 20 entering the base station 10 and before reaching the preset docking position of the base station 10, if the traction force of the cleaning robot 20 decreases, the raised portion 113 can engage with the driving wheel 202 of the cleaning robot 20 to increase the deformation of the driving wheel 202 to improve the traction force of the cleaning robot 20 entering the base station 10, thereby playing a role in traction compensation, avoiding the phenomenon that the cleaning robot 20 cannot further move to the preset docking position due to the attenuation of the driving force of the driving wheel 202, the increase of the friction force, etc. when entering the base station 10, providing a guarantee for the cleaning robot 20 to move to the preset docking position smoothly, reliably and stably, thereby ensuring that the base station 10 can smoothly and efficiently maintain the cleaning robot 20.

[0048] It can be understood that the dust collecting part 112 includes a dust collecting port 1121. The dust outlet 201 of the cleaning robot 20 is connected to the dust collecting space of the dust collecting box of the cleaning robot 20. The dust collecting box is a component on the cleaning robot 20 for collecting dust and other garbage. When the cleaning robot 20 enters the base station 10 to the preset docking position, the base station 10 can use the dust collecting port 1121 to communicate with the dust outlet 201 to absorb the garbage in the dust collecting box, thereby eliminating the need for the user to pour out the garbage in the dust collecting box, thereby improving the user's experience.

[0049] In some embodiments, the driving wheel 202 of the cleaning robot 20 includes an elastic mechanism (not shown). The setting of the elastic mechanism can make the driving wheel 202 provide a certain degree of buffering when the driving surface of the cleaning robot 20 is uneven (for example, a pit with a large depression or an obstacle with a certain height), so that the cleaning robot 20 is more stable when driving. In addition, when the cleaning robot 20 is driving normally on the driving surface, the elastic mechanism is in a compressed state. When the driving wheel 202 of the cleaning robot 20 is not touching the ground or is suspended in the air (for example, being picked up or lifted), the driving wheel 202 will pop out under the resetting force of the elastic mechanism.

[0050] It can be understood that when the cleaning robot 20 is driving normally on the driving surface, it uses the driving wheels 202 located on the left and right sides and the universal wheels 204 located in the front or rear as fulcrums; because the dust collection port of the base station 10 is generally higher than the position next to it, in the process of the cleaning robot 20 entering the base station 10, there may be mutual friction between the dust outlet 201 of the cleaning robot 20 and the dust collection port of the base station 10 during docking, and the cleaning robot 20 may be lifted up by the dust collection port of the base station 10, resulting in the driving wheel 202 being in a critical state of being about to pop out before the cleaning robot 20 reaches the preset docking position of the base station 10. At this time, the driving force provided by the driving wheel 202 to the cleaning robot 20 to move forward will decrease, and the fulcrum of the cleaning robot 20 will gradually become the universal wheel 204 and the dust outlet 201.

[0051] In some embodiments, when the driving wheel 202 of the cleaning robot 20 pops outward under the action of the elastic mechanism and the traction force of the cleaning robot 20 entering the base station 10 is reduced, the protrusion 113 can increase the deformation of the driving wheel 202 by engaging with the driving wheel 202, so as to enhance the traction force of the cleaning robot 20 entering the base station 10, thereby ensuring that the cleaning robot 20 can move smoothly, reliably and stably to the preset docking position to achieve docking with the base station 10.

[0052] It can be understood that in the process of the cleaning robot 20 entering the base station 10, as the cleaning robot 20 continues to approach the preset docking position of the base station 10, the cleaning robot 20 will come into contact and friction with the supporting mechanism 11 of the base station 10 (for example, the dust outlet 201 of the cleaning robot 20 will come into contact and friction with the base station 10, or the bottom of the cleaning robot 20 will come into contact and friction with the dust collecting part 112 of the base station 10, or the dust outlet 201 of the cleaning robot 20 and the dust collecting port of the base station 10 will rub against each other during docking, etc.), thereby causing the traction force of the cleaning robot 20 entering the base station 10 to be reduced to a certain extent. In some embodiments, during the process of the cleaning robot 20 entering the base station 10 and before the cleaning robot 20 reaches the preset docking position of the base station 10, when the cleaning robot 20 is gradually lifted up by the dust collection port of the base station 10, the driving wheel 202 is in a state of being about to pop out, and the protrusion 113 can enhance the traction force of the cleaning robot 20 entering the base station 10 by engaging with the driving wheel 202, thereby ensuring that the cleaning robot 20 can move smoothly, reliably and stably to the preset docking position to achieve docking with the base station 10.

[0053] In some embodiments, the protrusion 113 is integrally connected to the bearing seat 111 or is separately connected. Exemplarily, the protrusion 113 is integrally connected to the bearing seat 111. The integrally formed design is usually more stable because the protrusion 113 and the bearing seat 111 are combined together, reducing the possibility of movement or looseness between the two, and can withstand the vibration and impact that may be caused when the cleaning robot 20 enters the base station 10, and is more durable, which helps to ensure that the protrusion 113 can engage with the driving wheel 202 of the cleaning robot 20 to increase the deformation of the driving wheel 202, so as to improve the traction of the driving wheel 202 entering the base station 10. In addition, the design of the protrusion 113 and the bearing seat 111 being integrally formed avoids the process of assembling the protrusion 113 and the bearing seat 111, thereby reducing the time and labor cost of the staff during the manufacturing and maintenance process.

[0054] In some embodiments, the protrusion 113 may also be separately connected to the supporting seat 111, and the two are connected by at least one of the following connection methods: adhesive connection, snap connection, screw locking connection, etc. The separate connection is convenient for cleaning or replacement of the two. For example, when the protrusion 113 needs to be replaced due to wear, the separate connection is convenient for removing the protrusion 113 for replacement at any time; for another example, the protrusion 113 can be designed to have different heights and installed to have different densities. The user can install the protrusions 113 of different heights according to their own needs or install the protrusions 113 to a denser or sparser degree; for another example, the protrusion 113 may easily accumulate dirt. When the user cleans the supporting seat 111, the protrusion 113 can be removed and then the protrusion 113 and the supporting seat 111 can be cleaned separately, so that the cleaning effect is better.

[0055] In some embodiments, the dust collecting port 1121 of the dust collecting section 112 is located behind the protruding portion 113 in the direction in which the cleaning robot 20 enters the base station 10. In this way, on the one hand, when the cleaning robot 20 is about to reach the preset docking position, even if the dust outlet 201 of the cleaning robot 20 and the dust collecting port 1121 of the base station 10 are docked and rubbed against each other, the driving wheel 202 of the cleaning robot 20 pops outward relative to the body 203 of the cleaning robot 20 (compared to driving on the driving surface), thereby causing the traction force of the cleaning robot 20 entering the base station 10 to decrease. At this time, the protruding portion 113 can engage with the driving wheel 202 in time to effectively improve the traction force of the cleaning robot 20 entering the base station 10, effectively ensuring that the cleaning robot 20 can move smoothly and reliably to the preset docking position, thereby achieving the docking of the cleaning robot 20 and the base station 10; on the other hand, the dust outlet 201 of the cleaning robot 20 is generally designed close to its dust collection box, and the position of the dust collecting port 1121 of the base station 10 corresponds to the dust outlet 201, so as to achieve the desired docking effect. Figure 2 For example, the dust box of the cleaning robot 20 is designed to be located in front of the forward direction, the dust outlet 201 is also designed to be located in the front, and the mop (not shown) is designed to be located at the rear. This is because the cleaning robot 20 enters the base station 10 backwards, that is, the direction of entering the base station is opposite to the normal forward direction.

[0056] See also Figure 1 In some embodiments, the number of the protrusions 113 is two, and the two protrusions 113 are arranged at intervals and engage with the two driving wheels 202 of the cleaning robot 20 respectively. The two protrusions 113 can engage with the two driving wheels 202 respectively, so that the traction force of each driving wheel 202 entering the base station 10 can be improved, so that the total traction force of the cleaning robot 20 entering the base station 10 is effectively increased, which greatly ensures that the cleaning robot 20 can move smoothly and reliably to the preset docking position. In other embodiments, the number of protrusions 113 can also be set to other numbers, such as one, three, four or more, which is not limited here.

[0057] See also Figure 1 , Figure 3 and Figure 4 In some embodiments, the protrusion 113 includes at least two bone positions 1131, and the bone positions 1131 are convexly arranged on the tire groove of the bearing seat 111; the at least two bone positions 1131 are arranged at intervals along the direction of the cleaning robot 20 entering the base station 10. The driving wheel 202 includes at least two bite grooves 2021, and the at least two bone positions 1131 are respectively correspondingly engaged with the at least two bite grooves 2021.

[0058] refer to Figure 6In some embodiments, the driving wheel 202 includes an engagement groove 2021 and a ground contact surface 2022. For example, the engagement groove 2021 and the ground contact surface 2022 are arranged at intervals on the circumferential surface of the driving wheel 202; the ground contact surface 2022 is the portion of the cleaning robot 20 that contacts the driving surface (e.g., the cleaning ground) during driving, and the engagement groove 2021 is arranged concavely toward the central axis of the driving wheel 202 relative to the ground contact surface 2022, that is, the portion that does not contact the driving surface during normal driving. For example, at least two engagement grooves 2021 and the ground contact surface 2022 are respectively arranged in the axial direction of the driving wheel 202, and at least two engagement grooves 2021 arranged in the axial direction of the driving wheel 202 are staggered, and at least two ground contact surfaces 2022 are also staggered, that is, in the axial direction of the driving wheel 202, the engagement groove 2021 and the ground contact surface 2022 are opposite to each other.

[0059] In some embodiments, the circumferential surface of the driving wheel 202 includes at least two circles, and each circle is formed by an interlaced arrangement of an engagement groove 2021 and a ground contact surface 2022. In some embodiments, the at least two bone positions 1131 arranged at intervals can be arranged in a straight line or in an oblique line along the direction of the cleaning robot 20 approaching the base station, that is, when the at least two bone positions 1131 are arranged in a straight line, they respectively engage with the at least two engagement grooves 2021 on the same circle; when the at least two bone positions 1131 are arranged in an oblique line, they respectively engage with the at least two engagement grooves 2021 on different circles.

[0060] In some embodiments, the height of the bone position 1131 can be less than, equal to, or greater than the depth of the occlusal groove 2021, the width of the bone position 1131 can be less than, equal to, or greater than the width of the occlusal groove 2021, the length of the bone position 1131 can be less than, equal to, or greater than the length of the occlusal groove 2021, and the shape of the bone position 1131 can be a cuboid, a cube, a trapezoid, a curved surface, or any other three-dimensional structure. The present application does not limit the number, height, width, shape, and arrangement of the bone positions 1131, which can be set according to actual needs.

[0061] The protrusion 113 of this structure, at least two bone positions 1131 of the protrusion 113 can respectively engage with the engagement grooves 2021 of the driving wheel 202 to further increase the engagement force between the protrusion 113 and the driving wheel 202, thereby further improving the traction force of the driving wheel 202 into the base station 10. The protrusion 113 has a simple structure, ingenious design, and is easy to process. For example, please refer to Figure 3 and Figure 4 The two engagement grooves 2021 of the driving wheel 202 of the cleaning robot 20 respectively engage with the two bone positions 1131 of the protruding portion 113. Exemplarily, two adjacent tire teeth of the driving wheel 202 are arranged at intervals to form the engagement grooves 2021.

[0062] In some embodiments, the raised portion 113 is a rough surface provided on the tire groove, that is, a rough surface is provided on the tire groove (the rough surface is provided separately from the tire groove or provided integrally) or the surface of the tire groove is directly provided to be rough, thereby increasing the deformation of the driving wheel 202, and the rough surface can be engaged with the driving wheel 202 to a certain extent (for example, the rough part of the rough surface is engaged with the engagement groove 2021, and for another example, the rough part of the rough surface contacts and deforms the ground contacting surface 2022). The present application does not limit the roughness, size, form, etc. of the rough surface, and it can be set according to actual needs.

[0063] In some embodiments, the raised portion 113 is a convex point provided on the tire groove, and there is one or more convex points. The multiple convex points can be discretely distributed or distributed at positions corresponding to the engaging groove 2021 of the driving wheel 202. For example, the convex point is provided at a position on the tire groove that is further back along the direction in which the cleaning robot enters the base station. The size of the convex point can be the same as the size of the engaging groove 2021, that is, the convex point can be fully engaged with the engaging groove 2021. The present application does not limit the number, size, and arrangement of the convex points, and they can be provided according to actual needs.

[0064] In other embodiments, the protrusion 113 may also be any other suitable structure as long as it can increase the deformation of the driving wheel 202 to enhance the traction of the cleaning robot 20 entering the base station 10 .

[0065] See also Figure 5 In some embodiments, the dust collecting port 1121 and / or the dust outlet 201 are provided with a flexible member 30, and the flexible member 30 is provided between the dust collecting port 1121 and the dust outlet 201. When the cleaning robot 20 reaches the preset docking position of the base station 10, the universal wheel 204 of the cleaning robot 20 contacts the bearing seat 111, and the dust collecting port 1121 and / or the dust outlet 201 can squeeze the flexible member 30. The provision of the flexible member 30 can reduce the tolerance between the dust collecting port 1121 and the dust outlet 201 itself, which is conducive to improving the sealing performance of the dust collecting port 1121 and the dust outlet 201 after docking, and reducing the probability of dirt leaking at the connection between the dust collecting port 1121 and the dust outlet 201. Under the condition of achieving the same dust collection effect, it is conducive to reducing the power consumption of the dust collecting motor of the base station 10 and reducing the noise during dust collection.

[0066] It is understandable that when the cleaning robot 20 is docked at the base station 10, the contact surface between the dust collection port 1121 and the dust outlet 201 is slightly uneven due to tolerance, which may easily cause a gap and cause garbage to leak easily. In this embodiment, by providing a flexible member 30, the negative pressure provided when the base station 10 performs dust collection operation can increase the deformation of the flexible member 30, thereby effectively eliminating the gap between the dust collection port 1121 and the dust outlet 201 and causing poor sealing. The flexible member 30 can achieve effective sealing between the dust outlet 201 and the dust collection port 1121 when the dust outlet 201 is docked with the dust collection port 1121.

[0067] Exemplarily, the flexible member 30 includes at least one of the following: a soft rubber member, a foam member, etc. Exemplarily, the flexible member 30 can be connected to the dust collection port 1121 and / or the dust outlet 201 by at least one of the following methods: a glue point connection, a snap connection, etc. Exemplarily, the flexible member 30 is detachably connected to the dust collection port 1121 and / or the dust outlet 201. When the flexible member 30 is worn or fails, the flexible member 30 can be replaced, thereby extending the service life of the base station 10 and / or the cleaning robot 20 and improving the user experience.

[0068] See also Figure 3 The embodiment of the utility model further provides a cleaning system 100 , including a cleaning robot 20 and a base station 10 according to any one of the above embodiments, wherein the cleaning robot 20 performs maintenance in the base station 10 .

[0069] Exemplarily, the cleaning robot 20 includes the cleaning robot 20 of any one embodiment of the present invention.

[0070] In some embodiments, the cleaning system 100 further includes a drag reducing member (not shown), which is disposed at the dust collecting port 1121 and / or the dust outlet 201, and is used to reduce the friction between the cleaning robot 20 and the dust collecting port 1121. The drag reducing member can reduce the friction coefficient of the cleaning robot 20 entering the base station 10, effectively reduce the risk of wear of the dust outlet 201 and / or the dust collecting port 1121, improve the stability of the cleaning robot 20 entering the base station 10, and help to improve the success rate of the cleaning robot 20 reaching the preset docking position of the base station 10. Exemplarily, the drag reducing member includes a Teflon member or other structure capable of reducing the friction coefficient. Exemplarily, the drag reducing member can be a one-piece structure disposed on the dust collecting port 1121 and / or the dust outlet 201, or can be a coating type.

[0071] See also Figure 5In some embodiments, the cleaning system 100 further includes an inclined surface 40, which is disposed at the bearing seat 111 and / or the cleaning robot 20; the inclined surface 40 is inclined near the dust collection port 1121 and / or the dust outlet 201, and the inclined surface 40 is disposed behind the dust collection port 1121 and / or the dust outlet 201 along the direction of the cleaning robot 20 entering the base station 10; the height of the inclined surface 40 gradually increases along the direction of the cleaning robot 20 entering the base station 10. For example, the inclined surface 40 is disposed at the bearing seat 111, and the height of the inclined surface 40 is the distance of the inclined surface 40 relative to the bearing seat 111. For another example, the inclined surface 40 is disposed at the bottom of the cleaning robot 20, and the height of the inclined surface 40 is the distance of the inclined surface 40 relative to the bottom surface of the cleaning robot 20. For another example, the inclined surface 40 is disposed at both the bearing seat 111 and the bottom of the cleaning robot 20. It can be understood that in order to reduce the resistance of the cleaning robot 10 when entering the base station 20, the inclined surface 40 is designed to be as flat as possible, thereby reducing the resistance caused by the sudden change in the center of gravity of the cleaning robot 20 when crossing the protrusion (corresponding to the dust collection port 1121 of the base station 10).

[0072] See also Figure 2 In some embodiments, the cleaning robot 20 includes a body 203, a universal wheel 204 and two driving wheels 202, and the universal wheel 204 and the two driving wheels 202 are connected to the body 203. In some embodiments, the two driving wheels 202 are symmetrically arranged on both sides of the body 203 about the axis of gravity of the cleaning robot 20, and the universal wheel 204 is located on the axis of gravity; when the cleaning robot 20 reaches the preset docking position of the base station 10, the dust collecting part 112 and the dust outlet 201 are arranged close to the axis of gravity. In this way, after the cleaning robot 20 reaches the preset docking position of the base station 10, since the dust collecting part 112 is arranged close to the axis of gravity, it can ensure that the cleaning robot 20 can be stably and reliably parked on the bearing seat 111 only by the contact fulcrum of the universal wheel 204 and the bearing seat 111, and the fulcrum of the dust outlet 201 and the dust collecting port 1121 docking, without the need to set up other additional support structures, which is conducive to simplifying the structure of the base station 10 and the cleaning robot 20. For example, the center of gravity axis of the cleaning robot 20 is as follows: Figure 2 As shown by the dotted line m in FIG. illustratively, when the cleaning robot 20 reaches the preset docking position of the base station 10, the distance between the dust collecting part 112 and the central axis is between [0, 60 mm].

[0073] Exemplarily, the dust outlet 201 of the cleaning robot 20 is disposed on the body 203 .
