Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to a base station and cleaning system. Background Technology

[0002] In the modern smart home ecosystem, after the cleaning robot returns to the base station, the base station will charge the robot. If there is poor contact between the robot's charging connection and the base station's charging connection, i.e., a loose connection, electrical sparks may be generated, leading to oxidation of the charging connection.

[0003] When the charging and connection terminals are oxidized, their conductivity decreases significantly, directly leading to a reduction in charging efficiency. This can further cause serious problems such as the equipment failing to start normally and charging interruptions, ultimately affecting the normal operation of the entire cleaning equipment.

[0056] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

As another example, at least one of a, b, or c can represent: a, b, c, a+b, a+c, b+c, a+b+c, where a, b, and c can be single or multiple.

[0059] To illustrate the technical solutions described in this application, the following detailed description is provided in conjunction with specific accompanying drawings and embodiments.

[0060] like Figure 1 As shown, this application embodiment first provides a cleaning system 100, which includes a base station 20 and a cleaning device 30 capable of docking with the base station 20. The cleaning device 30 is a self-propelled robot.

[0061] The cleaning equipment 30 can be a sweeping robot, a mopping robot, or a sweeping and mopping robot.

[0062] like Figure 2 and Figure 3 As shown, the base station 20 includes a housing 21, on which a receiving cavity 22 is formed. The receiving cavity 22 is used to receive a portion of the cleaning equipment 30 returned to the base station 20. The base station 20 also includes a power module 24 disposed in the internal space of the housing 21, and a charging assembly 25 disposed in the housing 21. The charging assembly 25 includes a charging terminal 2511 that is connected to the power module 24 and is conductive.

[0063] The power module 24 here can be a battery or other energy storage and power supply module, or a connector that can be connected to the public power grid. Whether it is a battery or a connector that can be connected to the public power grid, it can also be connected to a current and voltage processing circuit, which can perform rectification, filtering, voltage conversion or voltage regulation.

[0064] The cleaning device 30 is equipped with a battery (not shown) and a connection terminal (not shown) that connects to the battery and can mate with the charging terminal 2511. When the cleaning device 30 returns to the base station 20 and is in a predetermined position within the base station 20, the connection terminal and the charging terminal 2511 can come into contact. When the connection terminal and the charging terminal 2511 make physical contact, the power module 24 can charge the battery in the cleaning device 30 through the charging component 25 and the connection terminal.

[0065] In the embodiments of this application, the charging component 25 has a first state and a second state. In the first state, the charging component 25 can abut against the connection end of the cleaning device 30 located in the accommodating cavity 22, and at this time, the cleaning device 30 can be charged. In the second state, the charging component 25 is spaced apart from the connection end of the cleaning device 30 located in the accommodating cavity 22. At this time, the electrical connection between the power module 24 and the cleaning device 30 is disconnected, and even if the cleaning device 30 is in a predetermined position, it cannot be charged.

[0066] The cleaning system 100 provided in this application embodiment can control whether the cleaning device 30 is charging by controlling the state of its charging component 25 when it returns to the base station 20, so as to avoid the situation where the cleaning device 30 starts charging as soon as it returns to the base station 20.

[0067] For example, at the moment when the cleaning device 30 returns to the base station 20, the cleaning device 30 itself has a certain speed and vibration. At this time, the charging component 25 can be controlled to be in the second state to avoid the connection between the connection end of the cleaning device 30 and the charging end 2511 being loose, as well as the frequent pile-down problems caused by the loose connection.

[0068] For example, when the battery power of the cleaning device 30 reaches a certain value, such as greater than or equal to 40%, greater than or equal to 50%, greater than or equal to 60%, or greater than or equal to 70%, the charging component 25 can be controlled to be in a second state. This eliminates the need for frequent charging of the cleaning device 30 returning to the base station 20, preventing battery performance degradation. Similarly, for a cleaning device 30 with a mopping function, when the cleaning device 30 returning to the base station 20 is washing a cloth, the charging component 25 can be controlled to be in a second state, allowing the cleaning device 30 to power the cloth washing process using its own battery. This allows the cleaning device 30 to power the cloth washing process using its own battery, expanding its operating scenarios. For example, in the event of a power outage at the user's home, the cleaning device 30 can also use its own battery to power the cloth washing process.

[0069] For example, during the day or peak electricity consumption periods, the charging component 25 can be controlled to be in the second state, so that the cleaning equipment 30 returning to the base station 20 does not need to be charged. At night or during off-peak electricity consumption periods, the charging component 25 can be controlled to be in the first state, allowing the cleaning equipment 30 to be charged via the base station 20.

[0070] In this way, the cleaning device 30 can choose whether to connect and electrically connect with the charging terminal 2511 according to the charging needs, avoiding the problem of the cleaning device 30 returning to the base station 20 to charge, avoiding problems such as loose connection and easy oxidation caused by frequent contact between the charging terminal 2511 and the cleaning device 30, ensuring the conductivity reliability of the charging terminal 2511, further ensuring the charging reliability of the cleaning device 30, and improving the working performance of the cleaning device 30.

[0071] like Figure 2 and Figure 3 As shown, in some embodiments of this application, the housing 21 is further provided with an opening 23 communicating with its internal space. Specifically, at least one opening 23 is provided on any wall of the accommodating cavity 22. At least one charging terminal 2511 corresponds to at least one opening 23 and protrudes from the corresponding opening 23.

[0072] The aforementioned "charging terminal 2511 protruding from the corresponding opening 23" can include several situations: at least a portion of the charging terminal 2511 passes through the opening 23; the charging terminal 2511 is located inside the housing 21 and near the opening 23, and the connecting end can pass through the opening 23 and connect to the charging terminal 2511; the charging terminal 2511 is located outside the housing 21, inside the accommodating cavity 22, and near the opening 23, and the charging terminal 2511 is connected to the power module 24 inside the housing 21 via the opening 23.

[0073] like Figure 2 and Figure 3 As shown in some embodiments of this application, it should be noted that the accommodating cavity 22 is a semi-open structure formed by recessing from one side of the housing 21, and the accommodating cavity 22 is connected to the space inside the housing 21 via the opening 23.

[0074] The charging terminal 2511 includes two electrode terminals, serving as a positive output terminal and a negative output terminal, respectively. The two electrode terminals can be exposed in the same or different ways from the opening 23, as long as they can respectively abut against the connection terminal. The connection terminal includes two electrode terminals, serving as a positive input terminal and a negative input terminal, respectively.

[0075] There can be two openings 23, each corresponding to one of the two charging terminals 2511. Alternatively, in some embodiments, there can be only one opening 23, which can expose both charging terminals 2511 simultaneously. No particular limitation is made here.

[0076] The cleaning system 100 has a specific orientation during use and installation. For ease of description and understanding, three mutually perpendicular directions are defined in the space: the first direction X, the second direction Y, and the third direction Z, as follows: Figure 1 and Figure 2 As shown. The first direction X corresponds to the length of the cleaning system 100 and also to the left and right directions of the user; the second direction Y corresponds to the depth of the cleaning system 100 and also to the front and back directions of the user; and the third direction Z corresponds to the height of the cleaning system 100 and also to the up and down directions of the user.

[0077] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the front portion of the housing 21 of the base station 20 is recessed rearward to form a semi-open accommodating cavity 22. For example... Figure 2 As shown, the aforementioned opening 23 is provided on the rear side wall (i.e., its inner bottom wall) of the accommodating cavity 22. Correspondingly, the connection end of the cleaning device 30 is located on its rear side. In other embodiments, at least a portion of the opening 23 may be provided on the upper side wall, lower side wall, etc., of the accommodating cavity 22, as long as it can accommodate the position of the power module 24 within the housing 21.

[0078] Depending on the location of the opening 23 on the cavity wall of the receiving cavity 22, the opening direction of the opening 23 varies. For example, if the opening 23 is located on the inner bottom wall of the receiving cavity 22, then the opening 23 is opened along the front-to-back direction. In this case, the charging end 2511 protrudes from the opening 23 generally along the front-to-back direction and can abut against the connection end. Alternatively, if the opening 23 is located on the upper side wall of the receiving cavity 22, then the opening 23 is opened upwards. In this case, the charging end 2511 protrudes from the opening 23 generally along the downward direction. Other cases are similar and will not be elaborated further.

[0079] The cleaning device 30 also includes a circuit board (not shown) internally, which is electrically connected to its battery and has the aforementioned connection terminals. In some embodiments, the circuit board includes a charging circuit connected to the battery. In some optional embodiments, the charging circuit includes a switching element for controlling the on / off state of the charging circuit. That is, when the switching element is turned on and the charging terminal 2511 is physically connected to the connection terminal, the power module 24 can charge the battery; when the switching element is turned off, even if the charging terminal 2511 is physically connected to the connection terminal, the power module 24 cannot charge the battery. The switching element may be, for example, a field-effect transistor.

[0080] In some embodiments, the power module 24 of the base station 20 may include a switching element for controlling the on / off state of the circuit of the power module 24. When the switching element is on and the charging terminal 2511 is physically connected to the connection terminal, external power can charge the battery of the cleaning device 30 via the power module 24; when the switching element is off, even if the charging terminal 2511 is physically connected to the connection terminal, external power cannot charge the battery of the cleaning device 30 via the power module 24. The switching element may be, for example, a field-effect transistor.

[0081] In some embodiments, the switching elements of the power module 24 and the switching elements of the internal charging circuit of the cleaning device 30 can be selectively configured; alternatively, the switching elements of the power module 24 and the switching elements of the internal charging circuit of the cleaning device 30 can be configured simultaneously. When the charging terminal 2511 is physically connected to the connection terminal, the electrical connection between the charging terminal 2511 and the connection terminal can be disconnected by controlling any one of the switching elements. For example, after the charging terminal 2511 has finished charging the battery, the electrical connection can be disconnected by controlling the switching element. At this time, the cleaning device 30 is allowed to remain in the position of contacting the charging terminal 2511.

[0082] The first and second states of the charging component 25 can be implemented in various ways.

[0083] In some embodiments of this application, the charging end 2511 is movable.

[0084] As shown in the figure, in some embodiments of this application, the base station 20 further includes a driving member 253 for controlling the position of the charging terminal 2511. The driving member 253 is disposed inside the housing 21 and is connected to the charging terminal 2511. The driving member 253 is used to control the position of the charging terminal 2511, thereby controlling the charging assembly 25 to switch between a first state and a second state.

[0085] Optionally, in the first state of the charging assembly 25, the charging end 2511 is located in the first position, and in the second state of the charging assembly 25, the charging end 2511 is located in the second position. The driving member 253 can drive the charging end 2511 to move from the first position to the second position, so that the charging assembly 25 transitions from the first state to the second state.

[0086] In both the first and second states, the charging terminal 2511 may be located inside the housing 21; or, in the first state, the charging terminal 2511 extends from the opening 23 to a first position. The phrase "the charging terminal 2511 extends from the opening 23" may include the end of the charging terminal 2511 facing the cleaning device 30 being located within the opening 23 but not exceeding the edge of the opening 23, and the end of the charging terminal 2511 facing the cleaning device 30 passing through the opening 23 and located within the receiving cavity 22.

[0087] In some embodiments, the drive element 253 is capable of driving the charging end 2511 to move along a first straight line to move from a first position to a second position.

[0088] In some embodiments, such as Figure 3 and Figure 4 As shown, the first straight line is parallel to the depth direction of the base station 20. The driving component 253 is used to drive the charging end 2511 to translate in the depth direction of the base station 20, that is, to translate back and forth. The first position is located in front of the second position. The driving component 253 is used to drive the charging end 2511 to retract from the first position to the second position.

[0089] like Figure 3 As shown, in the first state, the first position of the charging terminal 2511 can be that the charging terminal 2511 is inside the housing 21 and aligned with the opening 23. Alternatively, in the first state, the charging terminal 2511 can be partially inserted into the opening 23, or even partially inserted into the receiving cavity 22 through the opening 23.

[0090] In some embodiments, such as Figure 3 and Figure 5 As shown, the first straight line is inclined to or even perpendicular to the depth direction of base station 20. Please refer to the comparison. Figure 3 and Figure 5 As shown, in the first state, the first position of the charging end 2511 can be that the charging end 2511 is inside the housing 21 and aligned with the opening 23. In the second state, the second position of the charging end 2511 can be that the charging end 2511 is inside the housing 21 and misaligned with the opening 23.

[0091] Optionally, the first straight line is perpendicular to the depth direction of the base station 20. Specifically, the first straight line can be in the vertical direction of the base station 20, or in the horizontal direction, or in the upper left or upper right direction, etc.

[0092] The purpose of this design is to minimize the space occupied by the charging terminal 2511 in the front-to-back direction within the housing 21, which helps the base station 20 and its housing 21 maintain a small volume.

[0093] In some embodiments, the drive member 253 can drive the charging end 2511 to rotate within a first plane to move from a first position to a second position. Optionally, in some embodiments, the drive member 253 can drive the charging end 2511 to rotate, such as circumferentially. See also... Figure 3 and Figure 5 As shown, after the charging end 2511 rotates inside the housing 21, it can be switched from a first position aligned with the opening 23 to a second position misaligned with the opening 23.

[0094] The first plane can be inclined to the depth direction of the base station 20, or even perpendicular to the depth direction of the base station 20. Optionally, the first plane is perpendicular to the depth direction of the base station 20. In this way, the space occupied in the front-to-back direction when the charging end 2511 rotates is smaller.

[0095] In other embodiments, the driving member 253 is used to drive the charging end 2511 to move along a first straight line and rotate in a first plane. The driving member 253 can be used to drive the charging end 2511 to move along the first straight line and rotate in the first plane at the same time, which is equivalent to the charging end 2511 moving from a first position to a second position in a spiral manner. Alternatively, the driving member 253 can be used to drive the charging end 2511 to move along the first straight line first and then rotate in the first plane, or to rotate in the first plane first and then move along the first straight line.

[0096] like Figure 6 and Figure 7 As shown, in some embodiments of this application, the charging assembly 25 further includes a blocking member, defined herein as a first blocking member 2512, which is connected to the driving member 253. The driving member 253 is used to drive the first blocking member 2512 to move. When the charging end 2511 is in the first position, the first blocking member 2512 is in the second position; when the charging end 2511 is in the second position, the first blocking member 2512 is in the first position. That is, the driving member 253 is used to drive the first blocking member 2512 and the charging end 2511 to exchange positions. When the charging end 2511 does not need to abut against the connection end, the first blocking member 2512 physically abuts against the connection end of the cleaning device 30.

[0097] When the charging terminal 2511 moves inside the housing 21, in the first state and the second state, the first blocking member 2512 may be located inside the housing 21 and exposed from the opening 23, or at least a portion of the first blocking member 2512 may be located inside the accommodating cavity 22.

[0098] When the charging end 2511 extends from the opening 23 to the first position in the first state, the first blocking member 2512 may be located inside the housing 21, or at least a portion of the first blocking member 2512 may be located inside the receiving cavity 22; in the second state, the first blocking member 2512 is located inside the housing 21, or at least a portion of the first blocking member 2512 is located inside the receiving cavity 22 and is exposed from the opening 23.

[0099] In the second state, the first blocking member 2512 is exposed through the opening 23. When the cleaning device 30 returns to the base station 20, its connection end forms a physical connection with the first blocking member 2512. Since the first blocking member 2512 is non-conductive, the power module 24 will not charge the battery.

[0100] In some embodiments, the method by which the driving member 253 drives the first blocking member 2512 to switch between the second position and the first position is not limited, and can refer to the method described above for the driving member 253 driving the charging end 2511. It should be noted that the process of the driving member 253 driving the first blocking member 2512 to move and the process of the driving member 253 driving the charging end 2511 to move do not interfere with each other. This can be achieved by distinguishing the movement path of the first blocking member 2512 and the movement path of the charging end 2511, and / or by controlling the sequence of movement of the first blocking member 2512 and the charging end 2511. In some optional embodiments, the driving member 253 may include a first sub-driving member and a second sub-driving member. The first sub-driving member is connected to the charging end 2511 and is used to drive the charging end 2511 to move between the first position and the second position. The second sub-driving member is connected to the first blocking member 2512 and is used to drive the first blocking member 2512 to switch between the second position and the first position. In other optional embodiments, a single set of driving members 253 can be used to control the exchange of positions between the first blocking member 2512 and the charging end 2511.

[0101] In some embodiments, such as Figure 8 and Figure 9 As shown, the driving member 253 is used to drive the charging end 2511 to switch between a first position and a second position, and to drive the blocking member to switch between a first position and a third position. Here, the blocking member is specifically defined as the second blocking member 252. When the charging end 2511 is in the first position, the second blocking member 252 is in the third position; when the charging end 2511 is in the second position, the second blocking member 252 is in the first position.

[0102] When the charging terminal 2511 moves inside the housing 21, in the first state, the second blocking member 252 may be located inside the housing 21 or at least partially located inside the accommodating cavity 22; in the second state, the charging terminal 2511 of the second blocking member 252 is exposed from the opening 23.

[0103] When the charging end 2511 extends from the opening 23 to the first position in the first state, the second blocking member 252 may be located inside the housing 21, or at least a portion of the second blocking member 252 may be located inside the accommodating cavity 22; in the second state, the charging end 2511 of the second blocking member 252 extends from the opening 23 to the first position.

[0104] In some alternative embodiments, the second blocking member 252 is fixedly connected to the charging end 2511 and moves synchronously under the drive of the driving member 253.

[0105] The driving member 253 can drive the second blocking member 252 and the charging end 2511 along the first straight line, or drive the second blocking member 252 and the charging end 2511 to rotate in the first plane, or drive the second blocking member 252 and the charging end 2511 to rotate simultaneously along the first straight line and in the first plane. Referring to the foregoing embodiments, further details are omitted here.

[0106] Taking the example of the driving component 253 driving the second blocking component 252 and the charging end 2511 to move along the first straight line. Figure 8 As shown, in the first state, the first position of the charging end 2511 can be that the charging end 2511 is inside the housing 21 and aligned with the opening 23, and the third position of the second blocking member 252 can be that it is located inside the housing 21 and offset from the opening 23, for example, located above the charging end 2511. Figure 9 As shown, in the second state, the second blocking member 252 is located in the first position, which may be inside the housing 21 and aligned with the opening 23, and the charging end 2511 is in the second position, located below the second blocking member 252.

[0107] Taking the example of the driving member 253 driving the second blocking member 252 and the charging end 2511 to rotate within a first plane. Optionally, the first plane is a plane perpendicular to the left-right direction of the base station 20. In the first state, the first position of the charging end 2511 can be that the charging end 2511 is inside the housing 21 and aligned with the opening 23, or it can be partially passing through the opening 23. The third position of the second blocking member 252 can be located in front of the charging end 2511, inside the accommodating cavity 22. In the second state, after the charging end 2511 rotates, it undergoes a backward movement in the front-back direction. The second blocking member 252 is in the first position, that is, after the second blocking member 252 rotates backward, it reaches the first position of being inside the housing 21 and aligned with the opening 23, or partially passing through the opening 23. For other embodiments, please refer to Figure 14 As shown, the second blocking member 252 and the charging end 2511 can move within the housing 21. For example, the first plane is a plane perpendicular to the depth direction of the base station 20. The driving member 253 drives the second blocking member 252 and the charging end 2511 to move alternately to the first position aligned with the opening 23. The form of the first blocking member 2512 is not limited.

[0108] like Figure 14 As shown, in some embodiments, the second blocking member 252 includes a conductive substrate 2521 and an insulating portion 2522 disposed on the conductive substrate 2521. The conductive substrate 2521 and the charging terminal 2511 can be integrally disposed. In other words, the first blocking member 2512 can be served by additionally providing an insulating portion 2522 on a larger area of ​​the charging terminal 2511.

[0109] In some embodiments, the first blocking member 2512 includes an insulating substrate, and the charging terminal 2511 is fixedly disposed on the insulating substrate. The first blocking member 2512 may be entirely an insulating substrate. That is, the charging terminal 2511 may be fixed to the second blocking member 252.

[0110] Please see Figure 10 and Figure 11 As shown, in some embodiments, the second blocking member 252 and the charging end 2511 are separately configured and have different movement paths. The driving member 253 may include a first sub-driving member and a second sub-driving member. The first sub-driving member is connected to the charging end 2511 and is used to drive the charging end 2511 to move between a first position and a second position. The second sub-driving member is connected to the second blocking member 252 and is used to drive the second blocking member 252 to switch between a third position and a first position.

[0111] The method by which the first sub-drive unit drives the charging terminal 2511 to switch between the first and second positions is not limited, and the method by which the second sub-drive unit drives the second blocking member 252 to switch between the third and first positions is not limited. The method by which the first sub-drive unit drives the charging terminal 2511 to switch between the first and second positions and the method by which the second sub-drive unit drives the second blocking member 252 to switch between the third and first positions can be different, so as to achieve different movement paths for the two.

[0112] Optionally, the first sub-driving member drives the charging terminal 2511 to translate along a first straight line or rotate within a first plane. See the above embodiments for details, which will not be repeated here.

[0113] The second sub-drive unit drives the second blocking member 252 to translate along a second straight line and / or rotate within a second plane. The second straight line is inclined to or even perpendicular to the depth direction of the base station 20. Optionally, the first straight line is perpendicular to the depth direction of the base station 20. Specifically, the first straight line can be the vertical direction of the base station 20, or the horizontal direction, or the upper left or upper right direction, etc.

[0114] The second plane can be inclined to the depth direction of the base station 20, or even perpendicular to the depth direction of the base station 20. Optionally, the second plane is perpendicular to the depth direction of the base station 20. In this way, the space occupied in the front-to-back direction when the second blocking member 252 rotates is smaller.

[0115] Please refer to the following: Figure 10 and Figure 11As shown, in one embodiment, the first straight line is parallel to the depth direction of the base station 20, and the driving member 253 drives the charging end 2511 to switch from the first position to the second position in a backward manner. The driving member 253 drives the second blocking member 252 to switch from the third position to the first position by translating on the second straight line perpendicular to the depth direction of the base station 20 or rotating in the second plane perpendicular to the depth direction of the base station 20.

[0116] In some embodiments, the base station 20 further includes a blocking member, specifically defined here as a third blocking member 254, and a driving member 253 is used to drive the third blocking member 254 to move. In the second state, the driving member 253 drives the third blocking member 254 to move to a fourth position. When the cleaning device 30 is in the accommodating cavity 22, the third blocking member 254 at the fourth position is located between the charging end and the connecting end, so that the charging end 2511 is spaced apart from the connecting end.

[0117] The drive member 253 is also used to drive the third blocking member 254 to move from the fourth position to the fifth position so that when the cleaning device 30 is in the receiving cavity 22, the charging end 2511 abuts against the connecting end.

[0118] In some embodiments, such as Figure 12 and Figure 13 As shown, the charging end 2511 can be a fixed setting.

[0119] For example, Figure 12 and Figure 13 As shown, the opening 23 is opened along the front-back direction. In the first state, the third blocking member 254 is away from the front end of the charging end 2511, and the front end of the charging end 2511 can abut against the connection end of the cleaning device 30 in the front-back direction.

[0120] In the first state, the charging terminal 2511 may be positioned such that it is located inside the housing 21 and aligned with the opening 23, or that it is at least partially located within the opening 23. The phrase "at least partially located within the opening 23" includes either that the charging terminal 2511 can partially extend into the opening 23, or that it can partially extend out through the opening 23 and be located within the receiving cavity 22.

[0121] In the first state, the third blocking member 254 is located inside the housing 21, or at least a portion of the third blocking member 254 is located inside the receiving cavity 22, as long as it can avoid the range of the opening 23 and prevent exposure from the opening 23; in the second state, the third blocking member 254 can be located inside the housing 21 and / or inside the receiving cavity 22, and exposed from the opening 23.

[0122] The manner in which the driving member 253 drives the third blocking member 254 to move between the fifth and fourth positions is not limited. For example, the driving member 253 drives the third blocking member 254 to move along a third straight line, or the driving member 253 drives the third blocking member 254 to rotate in a third plane, etc.

[0123] See Figure 12 and Figure 13 As shown, the driving member 253 drives the third blocking member 254 to move along a third straight line. The third straight line can be an inclined line or even a line perpendicular to the opening direction of the opening 23. For example, if the opening 23 is opened in the front-back direction, the third straight line can be parallel to the height direction of the base station 20, parallel to the width direction of the base station 20, or other lines perpendicular to the depth direction.

[0124] The driving member 253 drives the third blocking member 254 to rotate within a third plane, which can be an inclined plane or even a plane perpendicular to the opening direction of the opening 23. For example, if the opening 23 is opened along the front-back direction, the third plane can be perpendicular to the depth direction of the base station 20.

[0125] Depending on the position of the charging terminal 2511, the fifth and fourth positions of the third blocking member 254 can have different forms. For example, in the second state, at least a portion of the third blocking member 254 can be located within the receiving cavity 22; in the first state, the third blocking member 254 can at least partially pass through the side wall of the receiving cavity 22 and retract into the housing 21. Alternatively, in the second state, the third blocking member 254 can protrude from the inner side wall of the opening 23 to close or substantially close the opening 23, which is suitable when the charging terminal 2511 is positioned relatively far back. Furthermore, in both the first and second states, the third blocking member 254 can be located within the housing 21, which is suitable when the charging terminal 2511 is located within the housing 21.

[0126] Depending on the manner in which the driving component 253 drives the charging terminal 2511 and / or the blocking component to move, the driving component 253 is configured to output torque or output linear motion force. The specific structure of the driving component 253 can vary depending on the output form.

[0127] like Figure 14 As shown, in some embodiments of this application, the drive unit 253 includes a motor 2531 and a transmission unit 2532 connected to the output shaft of the motor 2531. The transmission unit 2532 may be configured to change the direction of the torque output by the motor 2531 or convert it into a linear motion force. The transmission unit 2532 may also be configured to decelerate the output of the motor 2531 so that the charging end 2511 moves at a suitable speed within a small range.

[0128] like Figure 14 As shown, taking the final output torque of the driving component 253 as an example, the transmission component 2532 includes a worm 2533 connected to the output shaft of the motor 2531, and a worm wheel 2534 meshing with the worm 2533. Taking the movement of the driving charging end 2511 and the first blocking component 2512 as an example, for every revolution of the worm 2533, the worm wheel 2534 rotates one tooth. Thus, the charging end 2511 and the first blocking component 2512 rotate with the worm wheel 2534.

[0129] In addition, in some alternative embodiments, the worm 2533 and the worm wheel 2534 can be self-locked, which helps to stably keep the charging end 2511 in the first or second state.

[0130] like Figure 15 As shown, taking the linear motion force ultimately output by the driving component 253 as an example, the transmission component 2532 includes a lead screw 2535 connected to the output shaft of the motor 2531 and a nut 2536 meshing with the lead screw 2535. Here, taking the movement of the second blocking component 252 as an example, the two second blocking components 252 are arranged on opposite sides of the nut 2536 (which can be used to correspond to the two openings 23 and the two electrode terminals). For each revolution of the motor 2531 and the lead screw 2535, the nut 2536 and the second blocking component 252 translate along the axial direction of the lead screw 2535 by a length equal to the pitch.

[0131] like Figure 16 As shown, taking the force of the final linear motion of the driving member 253 as an example, the transmission member 2532 includes a first gear 2537 connected to the output shaft of the motor 2531, and a rack 2539 meshing with the first gear 2537. Here, taking the driving of the second blocking member 252 as an example, two second blocking members 252 are spaced apart on the rack 2539.

[0132] In some alternative embodiments, to reduce the moving speed of the rack 2539, the transmission member 2532 may further include a second gear 2538 meshing between the first gear 2537 and the rack 2539. The second gear 2538 has more teeth than the first gear 2537.

[0133] In addition to the above, the drive member 253 and its transmission member 2532 may have more forms in other alternative embodiments.

[0134] like Figure 1 and Figure 2 As shown, in some embodiments of this application, the base station 20 further includes a ramp 26 connected to the front end of the housing 21. The ramp 26 gradually rises in a front-to-back direction to guide the cleaning equipment 30 up into the accommodating cavity 22 of the base station 20.

[0135] In some embodiments of this application, the base station 20 further includes a first sensor (not shown) disposed on the ramp 26. The first sensor is used to detect whether the cleaning device 30 is located on the ramp 26. The cleaning device 30 being located on the ramp 26 indicates that the cleaning device 30 is about to return to the receiving cavity 22 of the base station 20 and approach the opening 23. At this time, the driving component 253 can be controlled in advance based on the sensing signal of the first sensor, and the state of the charging terminal 2511 can be controlled in advance, so that the cleaning device 30 can form a connection with the charging terminal 2511 after returning to its position, or the cleaning device 30 cannot form a connection with the charging terminal 2511 after returning to its position.

[0136] The type of the first sensor is not limited; any method that can detect the cleaning device 30 is acceptable. For example, the first sensor may include a microswitch disposed on the ramp 26 to detect vibrations of the ramp 26. Alternatively, the first sensor may be a proximity sensor, such as a Hall effect sensor, which can be triggered when the cleaning device 30 approaches.

[0137] In some embodiments of this application, the cleaning device 30 may also be equipped with a second sensor, which is used to send the location of the cleaning device 30 to the base station 20. Therefore, in some optional embodiments, the location of the cleaning device 30 from the base station 20 can be obtained by the second location sensor, thereby determining whether the cleaning device 30 is about to return to the base station 20 and controlling the state of the charging terminal 2511 in advance.

[0138] In some embodiments of this application, the charging terminal 2511 may include a conductive base and a plating layer disposed on the conductive base. The plating layer has good anti-oxidation properties, which can prevent the surface of the charging terminal 2511 from being oxidized and reducing conductivity. For example, the conductive base may be a material with low resistivity such as copper or silver, and the plating layer may be a material such as nickel or silver. Specifically, the charging terminal 2511 may be copper plated with nickel or copper plated with silver.

[0139] In some embodiments of this application, the charging terminal 2511 is a charging spring. When subjected to a rearward force, the charging spring will undergo a certain amount of elastic deformation. Thus, the charging spring can maintain elastic contact with the connection terminal to achieve a reliable electrical connection between the two.

[0140] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
