Therefore, when the elastic portions of the electrode pieces are pushed by the charging terminals of the cleaning device, the movable arms can be further pushed to move relative to the base station body, thereby achieving two-stage buffering when the charging terminals of the cleaning device abut the elastic portions of the electrode pieces. This can further improve the stability of the abutment between the charging terminals of the cleaning device and the elastic portions of the electrode pieces, thereby improving the reliability of the charging of the cleaning device by the base station and enhancing the user experience.

It is to be understood that if a device were turned over so that its upper portion is below its lower portion, then the described component would be an upper component instead of a lower component. When a structure is "on" another structure, it can mean that the structure is formed integrally with the other structure or that the structure is "directly" on the other structure, or that the structure is "indirectly" on the other structure via another structure.

[0061] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first,” “second,” and “third,” etc., are used only as markers and are not a limitation on the number of objects.

[0062] Embodiments of this disclosure provide a cleaning system, such as Figure 1 As shown, the cleaning system includes a base station 10 and a cleaning device 20. The cleaning device 20 can be, for example, a robotic vacuum cleaner, a robotic mop, or a robotic vacuum and mop combo; the cleaning device 20 may include a device body, a drive module, a sensing module, a control module, a cleaning module, an energy module, and a human-machine interaction module. The base station 10 is used to dock with the cleaning device 20, allowing it to be parked. The cleaning device 20 can perform functions such as charging, self-cleaning, docking, wastewater discharge, and water replenishment on the base station 10.

[0063] In some embodiments, the device body is configured to automatically move along a target direction on a travel surface, which can be the surface to be cleaned by the cleaning device 20. If the cleaning device 20 is a sweeping and mopping robot, then the cleaning device 20 operates on the ground, which is the aforementioned operating surface.

[0064] In some embodiments, the drive module includes a drive wheel assembly. The drive module can control both the left and right wheels simultaneously. For more precise control of the machine's movement, the drive module preferably includes a left drive wheel assembly and a right drive wheel assembly, respectively. The left and right drive wheel assemblies are symmetrically arranged along a transverse axis defined by the device body.

[0065] In some embodiments, to enable the cleaning device 20 to move more stably or with greater mobility on the ground, the cleaning device 20 may include one or more steering wheels; wherein, the steering wheels may be driven wheels or driving wheels, and their structural forms include, but are not limited to, casters, and the steering wheels may be located in front of the driving wheel assembly. A drive motor provides power to the driving wheel assembly and / or the steering wheels.

[0066] In some embodiments, the perception module includes a position determining device located above the device body, a bumper located at the front portion of the device body, a cliff sensor and an ultrasonic sensor located at the bottom of the device body, an infrared sensor, a magnetometer, an accelerometer, a gyroscope, an odometer, and the like, which provide various position information and motion state information of the device body to the control module. For example, the front portion of the device body is provided with a bumper. When the driving wheel assembly propels the cleaning device 20 to walk on the ground during the cleaning process, the bumper detects one or more objects in the travel path of the cleaning device 20 via the sensor module, such as the infrared sensor. The cleaning device 20 can control the driving structure to respond to the objects, such as climbing over the steps, by the objects detected by the bumper, such as steps, obstacles, walls.

[0067] In some embodiments, the control module can comprehensively judge the current working state of the robot, such as climbing steps, passing through a threshold, being on a carpet, being stuck above or below a cliff, being full of dust, being picked up, and the like, by combining the distance information, speed information, and the like, fed back by the bumper, the cliff sensor and the ultrasonic sensor, the infrared sensor, the magnetometer, the accelerometer, the gyroscope, the odometer, and the like. It can also give specific next action strategies for different situations, so that the work of the cleaning device 20 is more in line with the requirements of the owner, and better user experience is achieved. Further, the control module can plan the most efficient and reasonable cleaning path and cleaning method based on the real-time map information drawn by SLAM (Simultaneous Localization and Mapping), which can improve the cleaning efficiency of the cleaning device 20.

[0068] In some embodiments, the cleaning module can include a dry cleaning module, or a dry and wet cleaning module. The dry cleaning module can include a roller brush assembly, an edge brush, and the like, and the wet cleaning module can include a cleaning head, a water tank, and the like.

[0069] In some embodiments, the energy module includes a rechargeable battery, such as a nickel-hydrogen battery or a lithium battery. The rechargeable battery can be connected with a charging control circuit, a battery pack charging temperature detection circuit, and a battery undervoltage monitoring circuit, which are connected with a single-chip microcomputer control circuit. The device body is connected with a charging pile for charging through the charging electrode arranged on the side or the bottom of the body.

[0070] In some embodiments, the human-computer interaction module includes a button on the device body panel for the user to select a function; it can also include a display screen and / or an indicator light and / or a loudspeaker to show the user the current state of the machine or the function selection item; it can also include a mobile phone client program. For path navigation type cleaning devices, the mobile phone client can show the user a map of the environment where the device is located and the position of the machine, and can provide the user with more rich and personalized function items.

[0071] In the related art, the cleaning device 20 can autonomously move to the base station 10 to charge after completing the mopping cleaning operation. However, since the cleaning device 20 autonomously moves to the base station 10 to charge, that is, the charging terminal of the cleaning device 20 and the charging electrode on the base station 10 are automatically contacted, and no human intervention is needed to determine whether the connection is successful, it is easy to occur that the contact between the charging terminal of the cleaning device 20 and the charging electrode on the base station 10 is poor, resulting in charging failure, thereby affecting the continuous operation of the cleaning device 20, and further affecting the user's use experience.

[0072] To solve the above technical problems, the present disclosure provides a base station 10, as shown in Figure 2 and Figure 3 The base station 10 includes a base station body 110, a charging module and a power supply module. The charging module includes an electrode assembly 120, the electrode assembly 120 includes a movable arm 121, an elastic member 123 and an electrode sheet 122, the movable arm 121 is movably connected with the base station body 110, the elastic member 123 is configured to apply a force to the connected movable arm 121 away from the base station body 110; the electrode sheet 122 includes a flexible part 1221, the flexible part 1221 is configured to abut against the charging terminal of the cleaning device 20; the power supply module is arranged on the base station body 110, and the power supply module is configured to supply power to the electrode sheet 122.

[0073] The base station 10 provided by the present disclosure, when the cleaning device 20 automatically moves to the base station 10 for charging, the charging terminals on the cleaning device 20 are in contact with the electrode sheets 122 of the electrode assembly 120 on the base station 10; because the charging terminals are in abutment with the elastic parts 1221 of the electrode sheets 122, through the movement of the cleaning device 20 on the base station 10, the elastic deformation of the elastic parts 1221 of the electrode sheets 122 pushed by the charging terminals can be caused, so as to realize the interference physical contact; at the same time, because the electrode sheets 122 are installed on the movable arm 121, the movable arm 121 can move relative to the base station body 110 by overcoming the elastic force of the elastic member 123, therefore, when the elastic parts 1221 of the electrode sheets 122 are pushed by the charging terminals of the cleaning device 20, the movable arm 121 can be further pushed to move relative to the base station body 110, so as to realize the two-stage buffering when the positive and negative charging terminals of the cleaning device 20 are in abutment with the elastic parts 1221 of the electrode sheets 122, further improve the stability of the abutment between the charging terminals of the cleaning device 20 and the elastic parts 1221 of the electrode sheets 122, and thus improve the reliability of the charging of the base station 10 to the cleaning device 20, so as to improve the user experience.

[0074] In the following, the charging module provided by the present disclosure will be described in detail.

[0075] In an embodiment, the charging module includes two groups of electrode assemblies 120 with opposite polarities, when the cleaning device 20 automatically moves to the base station 10 for charging, the positive and negative charging terminals on the cleaning device 20 are in contact with the electrode sheets 122 of the positive and negative electrode assemblies 120 on the base station 10 respectively, so as to realize the charging connection. Because the positive and negative charging terminals are in abutment with the elastic parts 1221 of the electrode sheets 122 of the positive and negative polarities, through the movement of the cleaning device 20 on the base station 10, the elastic deformation of the elastic parts 1221 of the electrode sheets 122 pushed by the positive and negative charging terminals can be caused, so as to realize the interference physical contact of the positive and negative polarities; at the same time, because the electrode sheets 122 are installed on the movable arm 121, the movable arm 121 can move relative to the base station body 110 by overcoming the elastic force of the elastic member 123, therefore, when the elastic parts 1221 of the electrode sheets 122 are pushed by the positive and negative charging terminals of the cleaning device 20, the movable arm 121 can be further pushed to move relative to the base station body 110, so as to realize the two-stage buffering when the positive and negative charging terminals of the cleaning device 20 are in abutment with the elastic parts 1221 of the electrode sheets 122, further improve the reliability of the charging of the base station 10 to the cleaning device 20, and further improve the user experience. Of course, one of the two groups of electrode assemblies with opposite polarities adopts the electrode assembly 120 provided by the present disclosure, and the other adopts a conventional setting. Among them, the charging module can include three groups, four groups or more groups of electrode assemblies with opposite polarities, which are not limited by the present disclosure.

[0076] In an embodiment, the movable arm is rotationally connected or telescopically connected with the base body. When the movable arm is rotationally connected with the base body, the movable arm and the base body can be rotationally connected through a rotation shaft; under the pushing of the cleaning device, the movable arm can rotate within a certain angle range relative to the base body. When the movable arm is telescopically connected with the base body, under the pushing of the cleaning device, the movable arm can be telescopically adjusted relative to the base body to adjust the position of the movable arm extending out of the base body. As can be seen, through the rotational connection or telescopic connection of the movable arm with the base body, the movable arm can be moved under the pushing of the cleaning device to realize two-stage buffering when the positive and negative charging terminals of the cleaning device 20 abut against the elastic part 1221 of the electrode sheet 122, thereby further improving the reliability of the base station 10 charging the cleaning device 20 and further improving the user experience. In the following, the rotational connection of the movable arm 121 with the base body 110 is exemplarily described.

[0077] In an embodiment, as shown in Figures 4-6 , the base body 110 is provided with a mounting bracket 112, and the movable arms 121 of the two groups of electrode assemblies 120 are respectively rotationally connected with the mounting bracket 112. The elastic member 123 is connected between the movable arm 121 and the mounting bracket 112 to apply an action force away from the mounting bracket 112 to the connected movable arm 121. That is, when the positive and negative charging terminals of the cleaning device 20 push the elastic part 1221 of the electrode sheet 122 and further push the movable arm 121 to rotate relative to the mounting bracket 112, the elastic member 123 provides an elastic action force to resist the rotation of the movable arm 121, and the movable arm 121 rotates by compressing the elastic member 123.

[0078] Among them, the mounting bracket 112 is fixed on the base body 110, for example, the mounting bracket 112 is fixedly connected with the shell 111 of the base body 110 to serve as a mounting structure of the charging module.

[0079] Among them, as shown in Figure 6 and Figure 7 , the mounting bracket 112 can be provided with a rotation shaft hole 113, and one end of the movable arm 121 is rotationally connected with the mounting bracket 112 through the rotation shaft 113 in the rotation shaft hole 113, which is convenient for mounting and stable in rotation structure. Of course, the rotation shaft 113 and the mounting bracket 112 or the movable arm 121 can be an integral structure, and the present disclosure does not limit this.

[0080] In one embodiment, the mounting bracket 112 is provided with a limiting structure, which is configured to restrict the rotation of the movable arm 121 relative to the mounting bracket 112 between a first position and a second position. By providing a limiting structure on the mounting bracket 112, when the movable arm 121 is not subjected to external force, the movable arm 121 is in the first position, which is most protruding relative to the mounting bracket 112, under the action of the elastic member 123 and in cooperation with the limiting structure; when the movable arm 121 is subjected to external force and rotates, the limiting structure restricts the rotation angle, allowing the movable arm 121 to rotate to the side of the rotating bracket at most to the second position, thereby forming a rotation limit on the movable arm 121.

[0081] The mounting bracket 112 can form a receiving space for assembling the movable arm 121, and the part of the movable arm 121 that is rotatably connected to the mounting bracket 112 can be located in the receiving space. At this time, the upper and lower side walls of the receiving space can form a limit on the movable arm 121 in its circumferential direction, and the side wall of the opening on the receiving space through which the movable arm 121 extends can form a limit on the rotation angle of the movable arm 121 relative to the mounting bracket 112.

[0082] Of course, mutually cooperating limiting structures can also be provided on the movable arm 121 and the mounting frame 112. For example, a limiting protrusion can be provided on the mounting frame 112 to limit the rotation angle of the movable arm 121; or, a limiting protrusion can be provided on the movable arm 121 and a limiting groove can be provided on the mounting frame 112 to cooperate with the limiting protrusion. The limitation of the sliding distance of the limiting protrusion in the limiting groove can limit the rotation angle of the movable arm 121 during installation; those skilled in the art can also provide other types of limiting structures, which are not limited in this disclosure.

[0083] In one embodiment, such as Figure 6 As shown, the movable arms 121 in the two opposing sets of electrode assemblies 120 rotate in opposite directions. The cleaning device 20 is typically circular. By having the movable arms 121 in the two opposing sets of electrode assemblies 120 rotate in opposite directions, when they contact the charging terminals on the cleaning device 20, the rotational trajectories of the two rotations are substantially perpendicular to the tangent at the location of the charging terminals on the cleaning device 20. This prevents excessive lateral displacement of the elastic portion 1221 of the electrode plate 122 in the circumferential direction of the cleaning device 20 when the rotating arms are pushed to rotate, thus ensuring a stable contact between the elastic portion 1221 of the electrode plate 122 and the charging terminals. Simultaneously, this also facilitates the layout of the two sets of electrode assemblies 120 within the pile body, improving space utilization and allowing for a smaller overall size of the pile body. Of course, the movable arms 121 in the two opposing sets of electrode assemblies 120 can also rotate in the same direction; this disclosure does not impose any limitation on this.

[0084] The two movable arms 121 of the two electrode assemblies 120 have the same or substantially the same rotating angle when subjected to the same pushing force, so that the elastic parts 1221 of the two electrode sheets 122 are reliably in abutting contact with the charging terminals of the cleaning device 20.

[0085] In an embodiment, the elastic member 123 is a torsion spring. The torsion spring includes two torsion arms, one of which is fixedly connected to the movable arm 121, and the other of which is fixedly connected to the mounting frame 112. The torsion spring can stably provide an elastic force to enable the movable arm 121 to rotate from the second position to the first position and be maintained in the first position. It can be understood that the elastic member 123 can also be a torsion spring, a spring, a tension spring, or other elastic part 1221 that can provide an elastic force to enable the movable arm 121 to switch from the second position to the first position and be maintained in the first position.

[0086] The torsion spring can be coaxially arranged with the rotating shaft 113, i.e., the torsion part of the torsion spring can be sleeved on the rotating shaft 113 to provide a stable torsion force.

[0087] The first torsion arm of the torsion spring is limited in the first clamping groove, and the second torsion arm of the torsion spring is limited in the second clamping groove. In this way, the torsion spring is mounted through the first clamping groove and the second clamping groove, and the movable arm 121 and the mounting frame 112 are movably connected through the torsion spring, which is simple in structure and convenient to install.

[0088] The first torsion arm of the torsion spring can be inserted into the first clamping groove, clamped in the first clamping groove, or bonded in the first clamping groove by an adhesive, and the second torsion arm of the torsion spring can be inserted into the second clamping groove, clamped in the second clamping groove, or bonded in the second clamping groove by an adhesive.

[0089] During the switching of the movable arm 121 between the first position and the second position, the included angle between the first clamping groove and the second clamping groove is smaller than the included angle between the first torsion arm and the second torsion arm of the torsion spring in a free state. That is, by reasonably setting the positions of the first clamping groove and the second clamping groove, the first torsion arm and the second torsion arm of the torsion spring are stressed, so that the movable arm 121 is switched from the second position to the first position and maintained in the first position under the action of the torsion spring.

[0090] Of course, the first torsion arm and the second torsion arm of the torsion spring can abut against the surfaces of the movable arm 121 and the mounting frame 112 facing each other to provide an elastic force to the movable arm 121 to enable the movable arm 121 to switch from the second position to the first position and be maintained in the first position.

[0091] In an embodiment, the two groups of electrode assemblies 120 with opposite polarities are identical. By making the two groups of electrode assemblies 120 with opposite polarities identical, when installed, the positive and negative installation positions can be distinguished, facilitating installation; at the same time, one electrode assembly 120 can be produced and used as a positive electrode or a negative electrode, the production cost is low, and the maintenance economy is high.

[0092] In the embodiment, when the two groups of electrode assemblies 120 with opposite polarities are assembled on the mounting frame 112, the two groups of electrode assemblies 120 can be distributed along the width direction of the base station 10, and one electrode assembly 120 is mirrored in the height direction of the base station 10 and symmetrical to the other electrode assembly 120 in the width direction, that is, when installed, the two groups of electrode assemblies 120 can not be distinguished by the positive and negative installation positions, and only need to be mirror symmetrical in the height direction of the base station 10.

[0093] Of course, the structures of the two groups of electrode assemblies 120 can also be identical, which can achieve the above technical effects, and the present disclosure does not limit this.

[0094] In an embodiment, the electrode sheet 122 includes a body part 1222 and an elastic part 1221, the body part 1222 is arranged on the movable arm 121, and the elastic part 1221 is connected with the body part 1222. By making the electrode sheet 122 include the body part 1222 and the elastic part 1221, the part abutting against the charging terminal of the cleaning device 20 can be made of a material with a high elastic modulus as the elastic part 1221, so that the electrode sheet 122 is in interference contact with the charging terminal; the part connected with the movable arm 121 can be made of a conductive material with good conductivity as the body part 1222, so as to improve the conductivity of the electrode sheet 122.

[0095] In the embodiment, the body part 1222 and the elastic part 1221 are in a split structure, so that the body part 1222 and the elastic part 1221 can be made of different materials. The body part 1222 and the elastic part 1221 can both be formed of a metal conductive material, and the body part 1222 and the elastic part 1221 can be fixedly connected by welding, which is reliable and has high stability. Of course, the body part 1222 and the elastic part 1221 can also be fixedly connected together by adhesion, threaded connection, clamping and the like. It can be understood that in some embodiments, the body part 1222 and the elastic part 1221 can be in an integral structure, that is, a piece of metal plate material can be formed by stamping, cutting and the like.

[0096] In an embodiment, the body part 1222 is clamped with the movable arm 121, that is, the electrode sheet 122 is clamped with the movable arm 121, facilitating assembly of the electrode sheet 122.

[0097] In the embodiment, the body part 1222 and the elastic part 1221 are in a split structure, so that the body part 1222 and the elastic part 1221 can be made of different materials. The body part 1222 and the elastic part 1221 can both be formed of a metal conductive material, and the body part 1222 and the elastic part 1221 can be fixedly connected by welding, which is reliable and has high stability. Of course, the body part 1222 and the elastic part 1221 can also be fixedly connected together by adhesion, threaded connection, clamping and the like. It can be understood that in some embodiments, the body part 1222 and the elastic part 1221 can be in an integral structure, that is, a piece of metal plate material can be formed by stamping, cutting and the like. Figure 8 , Figure 11 and Figure 14As shown, the part where the movable arm 121 is connected to the body part 1222 can be in a rectangular block shape, and the body part 1222 of the electrode sheet 122 can be in a U shape, i.e., the body part 1222 is sleeved on the outer circumferential surface of the part where the movable arm 121 is connected to the body part 1222, which is convenient to install.

[0098] In some embodiments, the clamping structure can be the cooperation of a clamping protrusion and a clamping groove, one of the clamping protrusion and the clamping groove is arranged on the body part 1222, and the other is arranged on the movable arm 121. When the electrode sheet 122 is installed in place on the movable arm 121, the clamping protrusion is located in the clamping groove to achieve limiting. It is preferred that the clamping protrusion is arranged on the electrode sheet 122. Since the electrode sheet 122 is made of metal material, it is convenient to arrange a tongue structure as the clamping protrusion. The movable arm 121 is made of insulating plastic material, and it is convenient to form the clamping groove through the injection molding process.

[0099] In an embodiment, an end of the body part 1222 away from the elastic part 1221 is provided with a conductive end 12221 connected to the charging module, and the electrode sheet 122 is electrically connected to the charging module through the conductive end 12221.

[0100] In some embodiments, the conductive end 12221 and the line of the charging module can be connected through tin soldering, or fixedly connected through the arrangement of fasteners such as threaded parts, and the present disclosure does not limit this.

[0101] In some embodiments, the conductive end 12221 can be provided with a through hole, which can be used as a connection structure 12212 with the line on one hand, and also as a stress release area on the other hand.

[0102] In an embodiment, at least part of the elastic part 1221 extends outward relative to the body part 1222 in the direction away from the base station body 110 in the rotation direction of the movable arm 121, i.e., the elastic part 1221 extends outward from the outer surface of the base station body 110, which is beneficial to contact with the charging terminal on the cleaning equipment 20.

[0103] In an embodiment, when the elastic part 1221 is compressed and deformed toward the side of the body part 1222 under the action of external force, the outermost part of the elastic part 1221 and the body part 1222 in the direction of movement away from the base station body 110 can be flush, i.e., in the process of abutting the charging terminal of the cleaning equipment and pushing the elastic part 1221 to compress and deform, the body part 1222 can also be abutted together, so as to realize the simultaneous contact with the body part 1222 and the elastic part 1221, and the body part 1222 and the elastic part 1221 are simultaneously powered.

[0104] When the body part 1222 is in poor contact with the charging terminal of the cleaning device due to dirt / oil, the elastic part 1221 can still be in conduction with the charging terminal of the cleaning device to achieve power supply. Since the movable arm 121 is rotationally connected to the base station body 110, during the process of the charging terminal of the cleaning device pushing the elastic part 1221 to compress and deform, the charging terminal and the elastic part 1221 slide relative to each other, so that the elastic part 1221 can scrape the contact surface of the charging terminal, thereby scraping the dirt / oil adhered to the contact surface of the charging terminal during the cleaning operation of the cleaning device, to ensure the conductivity of the charging terminal after contacting the body part 1222.

[0105] In an embodiment, as shown in Figure 9 , Figure 12 and Figure 15 , the body part 1222 is provided with at least one protruding part 1223, which is located on the body part 1222 and is directed away from the base station body 110 along the moving direction, i.e. during the process of the charging terminal of the cleaning device abutting and pushing the elastic part 1221 to compress and deform, the charging terminal of the cleaning device can contact the protruding part 1223 to supply power to the charging terminal through the protruding part 1223.

[0106] Among them, the body part 1222 can be provided with multiple protruding parts 1223, which can be distributed in multiple in the height direction and width direction of the body part 1222, so as to improve the contact area with the charging terminal and improve the conductivity.

[0107] Among them, the protruding part 1223 can be a protruding structure formed on the body part 1222 by stamping, i.e. the protruding part 1223 can be an integral molding structure of the body part 1222, which can improve the structural strength of the electrode sheet 122. Of course, the protruding part 1223 and the body part 1222 can also be connected together by welding, bonding, riveting, threaded connection and the like, which is not limited by the present disclosure.

[0108] In an embodiment, as shown in Figure 10 , Figure 13 and Figure 16 , the elastic part 1221 includes an elastic spring sheet 12211 connected with the body part 1222. By setting the elastic spring sheet 12211 as the elastic part 1221, the elastic performance of the elastic part 1221 is better, and the elastic part 1221 is deformed when contacting the charging terminal of the cleaning device 20, thereby improving the stable contact force.

[0109] The distance between the free end of the elastic spring 12211 and the body part 1222 is the largest in the direction away from the base station body 110, that is, the free end of the elastic spring 12211 is the farthest from the base station body 110, so that when the free end of the elastic spring 12211 contacts the charging terminal of the cleaning device 20, the free end of the elastic spring 12211 first contacts the charging terminal of the cleaning device 20, thereby enabling the elastic spring 12211 to provide a larger elastic force, and further improving the reliability of the contact with the charging terminal.

[0110] In an embodiment, as shown in Figure 10 , Figure 13 and Figure 16 , the free end of the elastic spring 12211 is formed with a folded edge 12214 folded toward the side of the movable arm 121. By forming the folded edge 12214 folded toward the side of the movable arm 121 at the free end of the elastic spring 12211, the structural strength of the free end of the elastic spring 12211 can be improved, and deformation in the extruded state can be avoided, thereby affecting the reliability of the contact with the charging terminal of the cleaning device 20. At the same time, the free end of the elastic spring 12211 is curved and arc-shaped, avoiding scratching the charging terminal of the cleaning device 20 or other parts of the cleaning device 20 when contacting the charging terminal of the cleaning device 20.

[0111] The folded edge 12214 can be a bending structure formed by sheet metal at the free end of the elastic spring 12211.

[0112] In an embodiment, as shown in Figure 9 , Figure 10 , Figure 12 and Figure 13 , the elastic spring 12211 is in the form of a sheet, that is, the elastic spring 12211 can be in the form of a spring arm. When the sheet-shaped elastic spring 12211 contacts the charging terminal of the cleaning device 20, the sheet-shaped elastic spring 12211 can provide a reliable elastic force by deforming, and the trajectory of the movement of the free end of the elastic spring 12211 can be substantially perpendicular to the tangent line at the position where the charging terminal of the cleaning device 20 is arranged, so that the contact position with the charging terminal is substantially unchanged.

[0113] It can be understood that in another embodiment, as shown in Figure 15 and Figure 16 , the elastic spring 12211 can be in the form of a U shape. The U-shaped elastic spring 12211 is equivalent to having two spring arms. When the two spring arms contact the charging terminal of the cleaning device 20, both the spring arms can provide an elastic force by deforming, so that the free end of the elastic spring 12211 stably contacts the charging terminal of the cleaning device 20.

[0114] In an embodiment, as shown in Figure 10 , Figure 13 andFigure 16 As shown, the elastic part 1221 further comprises a connecting structure 12212, the connecting structure 12212 is connected with the body part 1222, and the elastic spring sheet 12211 is connected with the connecting structure 12212.

[0115] The connecting structure 12212 and the elastic spring sheet 12211 are in an integrated structure, that is, the connection stability between the elastic spring sheet 12211 and the body part 1222 is higher, thereby being capable of providing a stable elastic force.

[0116] In an embodiment, as shown in Figure 10 , Figure 13 and Figure 16 , the elastic part 1221 further comprises a positioning structure 12213, the positioning structure 12213 is connected with the connecting structure 12212, and the positioning structure 12213 is configured to cooperate with the movable arm 121 to form a limit for the elastic part 1221.

[0117] The connecting structure 12212 is arranged opposite to a side surface of the movable arm 121, and the positioning structure 12213 is arranged opposite to another side surface of the movable arm 121, for example, through abutting, to realize assembly positioning. The connecting structure 12212 and the positioning structure 12213 can both be sheet-shaped structures, to be attached together with the surface of the movable arm 121. In other embodiments, the positioning structure 12213 can also be a positioning protrusion or a positioning tongue, and the present disclosure does not limit this.

[0118] In an embodiment, as shown in Figures 8-10 , in the rotation direction of the movable arm 121, the connecting structure 12212 is located on a side of the body part 1222 that faces the inner side of the base station body 110; wherein the body part 1222 is provided with a notch 12222, and the elastic spring sheet 12211 extends out to the periphery of the base station body 110 through the notch 12222. By setting the notch 12222 to extend the elastic spring sheet 12211, the size of the body part 1222 can be set larger, thereby being capable of improving the stability of the connection between the body part 1222 and the movable arm 121, and further improving the reliability of the contact between the elastic part 1221 and the charging terminal of the cleaning equipment 20.

[0119] The size of the notch 12222 can only meet the extension of the elastic spring sheet 12211 and the deformation space of the elastic spring sheet 12211.

[0120] In an embodiment, as shown in Figures 11-16As shown, in the rotation direction of the movable arm 121, the connecting structure 12212 is located on the side of the body part 1222 towards the inside of the base station body 110, and the body part 1222 is provided with a through hole 12223, and the elastic spring piece 12211 extends to the periphery of the base station body 110 through the through hole 12223. By setting the through hole 12223 to extend the elastic spring piece 12211, the size of the body part 1222 can be set larger, thereby improving the stability of the connection between the body part 1222 and the movable arm 121, and further improving the reliability of the contact between the elastic part 1221 and the charging terminal of the cleaning equipment 20.

[0121] The size of the through hole 12223 is sufficient for the elastic spring piece 12211 to extend and have a deformation space.

[0122] In an embodiment, the protruding part 1223 is distributed around the notch 12222 or the through hole 12223, and the structural strength at the position where the notch 12222 or the through hole 12223 is provided on the body part 1222 can be improved by the protruding part 1223.

[0123] In an embodiment, when the movable arm 121 is telescopically connected with the base station body 110, the elastic member 123 can be arranged between the movable arm 121 and the base station body 110, and when the movable arm 121 is retracted towards the side of the base station body 110 under an external force, the elastic member 123 is compressed, and when the external force is removed, the movable arm 121 moves out of the side of the base station body 110 under the elastic restoring force of the elastic member 123.

[0124] The sliding guide structure can be arranged between the base station body 110 and the movable arm 121 to guide the telescopic movement of the movable arm 121 relative to the base station body 110.

[0125] In an embodiment, the base station 10 is formed with a parking area 130 for the cleaning equipment 20, and the cleaning equipment 20 autonomously moves to the parking area 130 of the base station 10 for charging, self-cleaning and other functions.

[0126] The elastic part 1221 of the electrode piece 122 of the charging module extends out of the shell of the parking area 130, and the rest of the charging module is accommodated in the shell to form a hidden assembly, thereby avoiding the influence of sewage, dust and other factors on the reliability of the charging module.

[0127] The elastic part 1221 of the electrode piece 122 of the two electrode assemblies 120 extends out of the shell opposite the entrance and exit of the parking area 130, so that when the cleaning equipment moves to the parking area 130, it can directly contact the charging terminal on the side wall of the cleaning equipment 20.

[0128] In an embodiment, the power supply module is configured to convert the external power supply into a power supply that can be input by the cleaning device, and then conduct the power supply to the electrode sheet 122 of the electrode assembly 120, i.e., the built-in charger in the base station 10; or the power supply module is configured to directly conduct the power supply that can be input by the cleaning device to the electrode sheet 122 of the electrode assembly 120, i.e., the base station 10 is connected to an external charger for power supply, at this time, the power supply module in the base station 10 can be a power cord, only for conducting electricity; or the power supply module is configured to store the external power supply in the battery, and can convert the electrical energy stored in the battery into a power supply that can be input by the cleaning device, to conduct the power supply to the electrode sheet 122 of the electrode assembly 120, i.e., the base station 10 is built-in charger and battery, and the present disclosure does not limit this.

[0129] The power supply module can be a power supply distributor of the base station 10, to deliver electrical energy to other electrical equipment on the base station 10.

[0130] In an embodiment, the cleaning device 20 includes a cleaning head, and a mop is arranged on the cleaning head to perform mopping cleaning work; the base station 10 is provided with a cleaning groove 140, and the cleaning device 20 can be placed on the cleaning groove 140 of the base station 10 after completing the mopping cleaning work, to perform self-cleaning of the mop on the cleaning head by the cleaning member in the cleaning groove 140.

[0131] The cleaning device 20 can be provided with a plurality of cleaning heads, each cleaning head can be correspondingly located in one cleaning groove 140, i.e., the number of cleaning grooves 140 can be the same as the number of cleaning heads, to simultaneously perform self-cleaning of the plurality of cleaning heads.

[0132] In an embodiment, the base station 10 further includes a liquid supply assembly. The liquid supply assembly includes a liquid supply nozzle 150 arranged on the base station 10, and the liquid supply nozzle 150 is connected to the liquid injection hole on the cleaning device 20, to supplement the cleaning liquid of the cleaning device 20.

Alternatively, the liquid supply assembly may include a liquid supply pipe and an electrically controlled valve connected to the liquid supply pipe. The cleaning liquid may be tap water, and the inlet of the electrically controlled valve may be connected to a tap water pipe. When liquid supply is required, the electrically controlled valve opens to supply tap water through the liquid supply nozzle 150 connected to the liquid supply pipe. By connecting to an external tap water source and utilizing water pressure, the number of components in the base station 10 is reduced, thus minimizing the size of the base station 10.
