[0061] The terms "a", "an", "the", "said" 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 express an open-ended inclusive meaning and mean that additional elements / components / etc. may exist in addition to the listed elements / components / etc.; the terms "first", "second" and "third" etc. are used merely as labels and are not intended to limit the quantity of their objects.

[0062] The embodiment of the present disclosure provides 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 may be, for example, a sweeping robot, a mopping robot, a sweeping and mopping robot, etc. The cleaning device 20 may include a device body, a driving module, a sensing module, a control module, a cleaning module, an energy module, and a human-computer interaction module, etc. The base station 10 is used to dock the cleaning device 20, that is, to park the cleaning device 20. The cleaning device 20 may perform functions such as charging, self-cleaning, docking, sewage discharge, and water replenishment on the base station 10.

[0063] In some embodiments, the device body is configured to automatically move along the target direction on the driving surface, which may be the surface to be cleaned by the cleaning device 20. The cleaning device 20 may be a sweeping and mopping robot, and the cleaning device 20 works on the ground, which is the above-mentioned operating surface.

[0064] In some embodiments, the drive module includes a drive wheel assembly, and the drive module can control the left wheel and the right wheel at the same time. In order to more accurately control the movement of the machine, it is preferred that the drive module includes a left drive wheel assembly and a right drive wheel assembly respectively. The left and right drive wheel assemblies are symmetrically arranged along the transverse axis defined by the device body.

[0065] In some embodiments, in order to enable the cleaning device 20 to move more stably or with stronger movement ability on the ground, the cleaning device 20 may include one or more steering wheels; wherein the steering wheel may be a driven wheel or a driving wheel, and its structural form includes but is not limited to a universal wheel, and the steering wheel may be located in front of the driving wheel assembly. The driving motor provides power to the driving wheel assembly and / or the steering wheel.

[0066] In some embodiments, the sensing module includes a position determination device located above the device body, a buffer located at the forward part of the device body, a cliff sensor and ultrasonic sensor, infrared sensor, magnetometer, accelerometer, gyroscope, odometer and other sensing devices located at the bottom of the device body, and provides various position information and motion state information of the device body to the control module. For example, the forward part of the device body is provided with a buffer, and when the driving wheel assembly propels the cleaning device 20 to walk on the ground during the cleaning process, the buffer detects one or more objects in the driving path of the cleaning device 20 via a sensor module, such as an infrared sensor, and the cleaning device 20 can control the driving structure to make the cleaning device 20 respond to the object, such as crossing the step, through the object detected by the buffer, such as a step, an obstacle, or a wall.

[0067] In some embodiments, the control module can combine the distance information and speed information fed back by the sensor devices such as the buffer, cliff sensor and ultrasonic sensor, infrared sensor, magnetometer, accelerometer, gyroscope, odometer, etc. to comprehensively judge the current working state of the sweeping robot, such as climbing stairs, crossing thresholds, getting on carpets, being on cliffs, being stuck above or below, dust box full, being picked up, etc., and will also give specific next action strategies for different situations, so that the work of the cleaning device 20 is more in line with the owner's requirements and has a better user experience. Furthermore, 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 may include a dry cleaning module, or a dry and wet cleaning module, wherein the dry cleaning module may include a roller brush assembly, a side brush, etc., and the wet cleaning module may include a cleaning head, a water tank, etc.

[0069] In some embodiments, the energy module includes a rechargeable battery, such as a nickel-metal hydride battery or a lithium battery. The rechargeable battery can be connected to a charging control circuit, a battery pack charging temperature detection circuit, and a battery undervoltage monitoring circuit, and the charging control circuit, the battery pack charging temperature detection circuit, and the battery undervoltage monitoring circuit are further connected to the single-chip microcomputer control circuit. The device body is charged by connecting to a charging pile through a charging electrode arranged on the side or below the fuselage.

[0070] In some embodiments, the human-machine interaction module includes buttons on the panel of the device body, which are used by the user to select functions; it may also include a display screen and / or an indicator light and / or a speaker, which display the current state of the machine or function selection items to the user; it may also include a mobile client program. For path navigation cleaning equipment, the mobile client can show the user a map of the environment where the equipment is located, as well as the location of the machine, and can provide the user with more abundant and humanized function items.

[0071] In the related art, after the cleaning device 20 completes the mopping cleaning operation, it can be autonomously moved to the base station 10 for charging. However, since the cleaning device 20 autonomously moves to the base station 10 for charging, that is, the charging terminal of the cleaning device 20 and the charging electrode on the base station 10 are automatically in contact, and there is no human intervention to determine whether the connection is successful, it is easy for the charging terminal of the cleaning device 20 to have poor contact with the charging electrode on the base station 10, resulting in charging failure, thereby affecting the continuous operation of the cleaning device 20, and further affecting the user's experience.

[0072] In view of the above technical problems, the present disclosure provides a base station 10, such as Figure 2 and Figure 3 As shown, 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 to the base station body 110, and 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 an elastic portion 1221, and the elastic portion 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 terminal on the cleaning device 20 contacts the electrode sheet 122 of the electrode assembly 120 on the base station 10; because the charging terminal abuts against the elastic portion 1221 of the electrode sheet 122, the movement of the cleaning device 20 on the base station 10 can cause the charging terminal to push the elastic portion 1221 of the electrode sheet 122 to undergo elastic deformation, thereby achieving interference physical contact; at the same time, because the electrode sheet 122 is installed on the movable arm 121, the movable arm 121 overcomes the elastic member The elastic force of 123 can move relative to the base station body 110. Therefore, when the charging terminal of the cleaning device 20 pushes the elastic part 1221 of the electrode sheet 122, it can further push the movable arm 121 to move relative to the base station body 110, so as to realize two-level buffering when the positive and negative charging terminals of the cleaning device 20 abut against the elastic part 1221 of the electrode sheet 122, and further improve the stability of the abutment between the charging terminal of the cleaning device 20 and the elastic part 1221 of the electrode sheet 122, thereby improving the reliability of the base station 10 charging the cleaning device 20, so as to enhance the user experience.

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

[0075] In one 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 contact the electrode sheets 122 of the positive and negative electrode assemblies 120 on the base station 10 respectively to achieve a charging connection. Since the positive and negative charging terminals are in contact with the elastic parts 1221 of the positive and negative electrode sheets 122, the movement of the cleaning device 20 on the base station 10 can enable the positive and negative charging terminals to push the elastic parts 1221 of the positive and negative electrode sheets 122 to undergo elastic deformation, thereby achieving interference physical contact between the positive and negative electrodes. At the same time, since the electrode sheet 122 is 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 positive and negative charging terminals of the cleaning device 20 push the elastic parts 1221 of the positive and negative electrode sheets 122, the movable arm 121 can be pushed to move relative to the base station body 110, so as to achieve two-level buffering when the positive and negative charging terminals of the cleaning device 20 are in contact with the elastic parts 1221 of the electrode sheets 122, thereby further improving the reliability of the base station 10 charging the cleaning device 20, and further improving the user experience. Of course, one of the two groups of electrode assemblies with opposite polarities uses the electrode assembly 120 provided by the present disclosure, and the other uses a conventional setting. The charging module may include three, four or more groups of electrode assemblies with opposite polarities, which is not limited by the present disclosure.

[0076] In one embodiment, the movable arm is rotatably connected or telescopically connected to the base station body. When the movable arm is rotatably connected to the base station body, the movable arm and the base station body can be rotatably connected through a rotating shaft; the movable arm can be rotated within a certain angle range relative to the base station body under the push of the cleaning equipment. When the movable arm is telescopically connected to the base station body, the movable arm can be telescoped relative to the base station body under the push of the cleaning equipment to adjust the position of the base station body. It can be seen that through the rotatable connection or telescopic connection between the movable arm and the base station body, the movable arm can be moved under the push of the cleaning equipment to achieve two-level buffering when the positive and negative charging terminals of the cleaning equipment 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 equipment 20, so as to further improve the user experience. Below, the rotatable connection between the movable arm 121 and the base station body 110 is used as an example.

[0077] In one embodiment, if Figures 4 to 6 As shown, a mounting frame 112 is provided on the base station body 110, and the movable arms 121 of the two groups of electrode assemblies 120 are respectively rotatably connected to the mounting frame 112, and the elastic member 123 is connected between the movable arm 121 and the mounting frame 112 to apply a force to the connected movable arm 121 away from the mounting frame 112, that is, when the positive and negative charging terminals of the cleaning equipment 20 push the elastic part 1221 of the electrode sheet 122 and then push the movable arm 121 to rotate relative to the mounting frame 112, the elastic member 123 provides an elastic force to block the rotation of the movable arm 121, and the movable arm 121 rotates by compressing the elastic member 123.

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

[0079] Among them, Figure 6 and Figure 7 As shown, the mounting frame 112 may be provided with a rotating shaft 113 hole, and one end of the movable arm 121 is connected to the mounting frame 112 through the rotating shaft 113 hole to achieve rotational connection, which is convenient for installation and has a stable rotation structure. Of course, the rotating shaft 113 and the mounting frame 112 or the movable arm 121 may be an integrated structure, and the present disclosure does not limit this.

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

[0081] Among them, a receiving space for assembling the movable arm 121 can be formed on the mounting frame 112, and the part of the movable arm 121 that is rotatably connected to the mounting frame 112 can be located in the receiving space; at this time, the upper and lower side walls of the receiving space can be used to limit the movable arm 121 in its circumferential direction, and the side walls of the opening in the receiving space through which the movable arm 121 extends can be used to limit the rotation angle of the movable arm 121 relative to the mounting frame 112.

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

[0083] In one embodiment, if Figure 6 As shown, the rotation directions of the movable arms 121 in the two opposite sets of electrode assemblies 120 are opposite. The cleaning device 20 is usually circular. By making the rotation directions of the movable arms 121 in the two opposite sets of electrode assemblies 120 opposite, when abutting against the charging terminal on the cleaning device 20, the rotation trajectories of the two rotations can be substantially perpendicular to the tangent line at the location where the charging terminal of the cleaning device 20 is set, thereby avoiding the elastic part 1221 of the electrode sheet 122 from shifting too much in the circumferential direction of the cleaning device 20 when pushing the rotating arm to rotate, so that the elastic part 1221 of the electrode sheet 122 can maintain a stable abutment state with the charging terminal. At the same time, it is also beneficial to the layout of the two sets of electrode assemblies 120 in the pile body, improving the space utilization rate in the pile body, so that the outer dimensions of the pile body can be set smaller. Of course, the rotation directions of the movable arms 121 in the two opposite sets of electrode assemblies 120 can also be the same, and the present disclosure does not limit this.

[0084] When the movable arms 121 of the two groups of electrode assemblies 120 are subjected to the same thrust, the rotation angles of the two movable arms 121 are the same or substantially the same, so that the elastic parts 1221 of the two electrode sheets 122 maintain a reliable abutment state with the charging terminal of the cleaning device 20.

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

[0086] The torsion spring may be coaxially arranged with the rotating shaft 113 , that is, the torsion portion of the torsion spring may be sleeved on the rotating shaft 113 , so as to provide a stable torsional force.

[0087] The movable arm 121 may be provided with a first slot, the mounting frame 112 may be provided with a second slot, the first torsion arm of the torsion spring is limited in the first slot, and the second torsion arm of the torsion spring is limited in the second slot. Thus, the torsion spring is installed through the first slot and the second slot, and the movable arm 121 and the mounting frame 112 are movably connected through the torsion spring, which has a simple structure and is easy to install.

[0088] Among them, the first torsion arm of the torsion spring can be inserted into the first slot, clamped in the first slot, or bonded to the first slot through an adhesive, and the second torsion arm of the torsion spring can be inserted into the second slot, clamped in the second slot, or bonded to the second slot through an adhesive.

[0089] In the process of switching between the first position and the second position of the movable arm 121, the angle between the first clamping slot and the second clamping slot is smaller than the angle between the first torsion arm and the second torsion arm when the torsion spring is in a free state. That is, by reasonably setting the positions of the first clamping slot and the second clamping slot, the first torsion arm and the second torsion arm of the torsion spring are subjected to force, so that the movable arm 121 is switched from the second position to the first position without external force through the torsion spring and remains in the first position.

[0090] Of course, the first torsion arm and the second torsion arm of the torsion spring can respectively abut against the surfaces of the movable arm 121 and the mounting bracket 112 facing each other to provide elastic force to the movable arm 121 so that the movable arm 121 switches from the second position to the first position and remains in the first position.

[0091] In one embodiment, the two sets of electrode assemblies 120 with opposite polarities are the same. By making the two sets of electrode assemblies 120 with opposite polarities the same, it is not necessary to distinguish the positive and negative electrode installation positions during installation, which facilitates installation; at the same time, one electrode assembly 120 can be manufactured and used as a positive electrode or a negative electrode, which has low production costs and high maintenance economy.

[0092] Among them, when 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. After one of the electrode assemblies 120 is mirrored in the height direction of the base station 10, it is symmetrical with the other electrode assembly 120 in the width direction. That is, during installation, the two groups of electrode assemblies 120 do not need to distinguish between the positive and negative pole installation positions, and only need to be mirrored in the height direction of the base station 10.

[0093] Of course, the structures of the two groups of electrode assemblies 120 may also be the same as long as the above-mentioned technical effects can be achieved, and the present disclosure does not impose any limitation on this.

[0094] In one embodiment, the electrode sheet 122 includes a main body 1222 and an elastic part 1221, the main body 1222 is disposed on the movable arm 121, and the elastic part 1221 is connected to the main body 1222. By making the electrode sheet 122 include the main body 1222 and the elastic part 1221, a material with a higher elastic modulus can be used as the elastic part 1221 at the portion abutting against the charging terminal of the cleaning device 20, so that the electrode sheet 122 and the charging terminal are in interference contact; a conductive material with better conductive performance can be used as the main body 1222 at the portion connected to the movable arm 121, thereby improving the conductive performance of the electrode sheet 122.

[0095] Among them, the main body 1222 and the elastic part 1221 are split structures, which facilitates the main body 1222 and the elastic part 1221 to be made of different materials. The main body 1222 and the elastic part 1221 can both be formed of metal conductive materials, and the main body 1222 and the elastic part 1221 can be fixedly connected by welding, and the fixing method is reliable and has high stability. Of course, the main body 1222 and the elastic part 1221 can also be fixedly connected together by bonding, threading, clamping, etc. It can be understood that in some embodiments, the main body 1222 and the elastic part 1221 can be an integrated structure, that is, they can be formed by a piece of metal plate through stamping, cutting, etc.

[0096] In one embodiment, the main body 1222 is clamped with the movable arm 121 , that is, the electrode sheet 122 is clamped with the movable arm 121 , so as to facilitate the assembly of the electrode sheet 122 .

[0097] Among them, Figure 8 , Fig.11 and Fig.14As shown, the portion where the movable arm 121 is connected to the main body 1222 may be in a rectangular block shape, and the main body 1222 of the electrode sheet 122 may be in a U shape, that is, the main body 1222 is sleeved on the outer circumferential surface of the portion where the movable arm 121 is connected to the main body 1222, which is easy to install.

[0098] Among them, a snap-on structure can be provided on the main body 1222 of the electrode sheet 122 and the movable arm 121, so that after the electrode sheet 122 is assembled on the movable arm 121, the positioning connection is achieved through the cooperation of the snap-on structure to improve the assembly accuracy and assembly efficiency. In some embodiments, the snap-on structure can be a combination of a snap-on protrusion and a slot, one of which is provided on the main body 1222, and the other is provided on the movable arm 121. When the electrode sheet 122 is installed in place on the movable arm 121, the snap-on protrusion is located in the slot to achieve positioning. Preferably, a snap-on protrusion is provided on the electrode sheet 122. Since the electrode sheet 122 is made of metal, it is convenient to provide a tongue structure as a snap-on protrusion; the movable arm 121 is made of an insulating plastic material, which is convenient for forming a slot through an injection molding process.

[0099] In one embodiment, a conductive end 12221 connected to the charging module is disposed at one end of the main body 1222 away from the elastic portion 1221 , and the electrode sheet 122 is electrically connected to the charging module via the conductive end 12221 .

[0100] The conductive end 12221 and the circuit of the charging module may be connected by soldering, or by providing fasteners, such as screws, for fixed connection, and the present disclosure does not impose any limitation on this.

[0101] A through hole may be provided on the conductive end 12221 , and the through hole may serve as a connection structure 12212 with the circuit on one hand, and may also serve as a stress release area on the other hand.

[0102] In one embodiment, in the rotation direction of the movable arm 121, at least a portion of the elastic portion 1221 extends relative to the main body portion 1222 toward a side away from the base station body 110, that is, the elastic portion 1221 extends outside the outer surface of the base station body 110, which is convenient for contacting the charging terminal on the cleaning device 20.

[0103] In one embodiment, when the elastic portion 1221 is compressed and deformed toward the side of the main body 1222 under the action of an external force, the elastic portion 1221 and the outermost portion of the main body 1222 in the moving direction toward the side away from the base station body 110 can be flush, that is, in the process of the charging terminal of the cleaning equipment abutting against the elastic portion 1221 to push the elastic portion 1221 to compress and deform, it can also abut against the main body 1222, thereby achieving simultaneous contact with the main body 1222 and the elastic portion 1221, and power is supplied simultaneously through the main body 1222 and the elastic portion 1221.

[0104] When the main body 1222 has poor contact with the charging terminal of the cleaning device due to dirt / oil, the elastic part 1221 can still be connected to the charging terminal of the cleaning device to realize power supply. Since the movable arm 121 is rotatably connected to the base station body 110, when the charging terminal of the cleaning device pushes the elastic part 1221 to compress and deform, the charging terminal and the elastic part 1221 slide relative to each other, so that the contact surface of the charging terminal can be scraped by the elastic part 1221, so that the dirt / oil adhered to the contact surface of the charging terminal during the cleaning operation of the cleaning device can be scraped off, so as to ensure the conductivity of the charging terminal after contacting the main body 1222.

[0105] In one embodiment, if Fig. 9 , Fig.12 and Fig.15 As shown, at least one protrusion 1223 is provided on the main body 1222, and the protrusion 1223 is located on the main body 1222 along the moving direction toward the side away from the base station body 110, that is, in the process of the charging terminal of the cleaning device abutting against the elastic part 1221 to push the elastic part 1221 to compress and deform, the charging terminal of the cleaning device can contact the protrusion 1223, and the charging terminal is powered by the protrusion 1223.

[0106] Among them, a plurality of protrusions 1223 can be set on the main body 1222, and the plurality of protrusions 1223 can be distributed in the height direction and the width direction of the main body 1222, respectively, so as to increase the contact area with the charging terminal to improve the conductive performance.

[0107] The protrusion 1223 may be a protrusion structure formed by stamping on the body 1222, that is, the protrusion 1223 may be an integrally formed structure of the body 1222, which can improve the structural strength of the electrode sheet 122. Of course, the protrusion 1223 and the body 1222 may also be connected together by welding, bonding, riveting, threaded connection, etc., which is not limited in the present disclosure.

[0108] In one embodiment, if Fig.10 , Fig.13 and Fig.16 As shown, the elastic part 1221 includes an elastic spring 12211, and the elastic spring 12211 is connected to the body part 1222. By setting the elastic spring 12211 as the elastic part 1221, the elastic performance of the elastic part 1221 is better, and it is easy to deform when contacting the charging terminal of the cleaning device 20, thereby enhancing the stable contact force.

[0109] Among them, in the direction away from the base station body 110, the distance between the free end of the elastic spring 12211 and the main body 1222 is the largest, that is, the free end of the elastic spring 12211 extends the farthest relative to the base station body 110, so that when contacting 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, so that the elastic spring 12211 can provide a larger elastic force, thereby improving the reliability of contact with the charging terminal.

[0110] In one embodiment, if Fig.10 , Fig.13 and Fig.16 As shown, the free end of the elastic spring 12211 is formed with a flange 12214 that is folded toward one side of the movable arm 121. By forming the flange 12214 that is folded toward one 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 to avoid deformation under extrusion, thereby affecting the reliability of contact with the charging terminal of the cleaning device 20. At the same time, the free end of the elastic spring 12211 is a curved arc surface, which avoids 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 flange 12214 may be a bending structure formed by sheet metal at the free end of the elastic spring 12211 .

[0113] It is understood that in another embodiment, if Fig.15 and Fig.16 As shown, the elastic spring 12211 can be U-shaped. The U-shaped elastic spring 12211 is equivalent to having two elastic arms. When in contact with the charging terminal of the cleaning device 20, the two elastic arms can provide elastic force through deformation, so that the free end of the elastic spring 12211 is in stable contact with the charging terminal of the cleaning device 20.

The positioning structure 12213 is configured to cooperate with the movable arm 121 to limit the elastic portion 1221 .

[0117] The connection structure 12212 is disposed opposite to the side of the movable arm 121, and the positioning structure 12213 is disposed opposite to the other side of the movable arm 121, for example, by abutting to achieve assembly positioning. The connection structure 12212 and the positioning structure 12213 can both be sheet structures to fit 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, etc., which is not limited in the present disclosure.

By providing the notch 12222 to extend the elastic spring 12211, the size of the main body 1222 can be set larger, thereby improving the stability of the connection between the main body 1222 and the movable arm 121, and further improving the reliability of the elastic part 1221 contacting the charging terminal of the cleaning device 20.

[0119] The size of the notch 12222 is sufficient to allow the elastic spring 12211 to extend and to provide deformation space for the elastic spring 12211 .

By providing the through hole 12223 to extend the elastic spring piece 12211, the size of the main body 1222 can be set larger, thereby improving the stability of the connection between the main body 1222 and the movable arm 121, and further improving the reliability of the elastic part 1221 contacting the charging terminal of the cleaning device 20.

[0121] The size of the through hole 12223 is sufficient to allow the elastic spring 12211 to extend out and to provide deformation space for the elastic spring 12211 .

When the movable arm 121 is retracted toward one side of the base station body 110 by an external force, the elastic member 123 is compressed. When the external force is removed, the movable arm 121 extends out to one side of the base station body 110 and moves under the action of the elastic restoring force of the elastic member 123.

[0124] A sliding guide structure may be provided 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 .
