Description

Technical Field

[0001] This utility model relates to the field of charging base station technology, specifically to a charging base station and a cleaning system. Background Technology

[0002] With the continuous development of the smart home industry, handheld cleaning devices have been widely used in various life scenarios. After cleaning, handheld cleaning devices need to return to the charging base station for charging. During the process of moving the handheld cleaning device in the base station to lock into place, the charging connector needs to avoid the cleaning device. Only after the cleaning device is in place will the charging connector in the base station pop out and successfully connect with the charging connector of the cleaning device itself. Most existing charging base stations use a lever principle, squeezing a trigger to pop out the charging connector. During long-term use, as wear and tear increases, this may lead to delayed connector pop-out or unstable connection, potentially resulting in poor charging contact.

[0003] Therefore, there is an urgent need for a new type of charging base station. Utility Model Content

[0004] In view of this, the present invention aims to provide a charging base station and a cleaning system to solve the problem of unstable charging terminal ejection after long-term use of the charging base station in the prior art.

[0005] Firstly, this application proposes a charging base station, comprising: The base has an accommodating space, a first cavity is provided below the accommodating space, a enclosure structure is provided on the side of the accommodating space, the enclosure structure encloses and defines the accommodating space, a second cavity is provided inside the enclosure structure, the first cavity and the second cavity are connected, and a first clearance opening is provided on the side of the enclosure structure facing the accommodating space. The second charging terminal is movably disposed in the second cavity. The second charging terminal has an inward position within the second cavity and an extended position extending into the accommodating space via the first clearance opening. When the second charging terminal is in the extended position, it is used to electrically connect with the first charging terminal of the cleaning device placed in the accommodating space. A drive assembly is disposed within the first cavity or the second cavity, and the drive assembly is drively connected to the second charging terminal to drive the second charging terminal to move between the retracted position and the extended position.

[0006] The charging base station according to this application also includes: The detection component is mounted on the base; A control module is mounted on the base. The detection component and the drive component are communicatively connected. The detection component is used to send a positioning signal to the control module indicating that the cleaning equipment is in position. The control module is configured to: Based on the received positioning signal, the drive component is controlled to move the second charging terminal from the retracted position to the extended position.

[0007] Optionally, the charging base station further includes a bracket, on which the second charging terminal is provided. The driving assembly includes a driving part and a pushing member, which are convexly connected. When the charging base station has a control module, the driving part is communicatively connected to the control module. When the driving part is running, it drives the pushing member to move so that the bracket drives the second charging terminal from the retracted position to the extended position.

[0008] Optionally, the charging base station also includes: A reset member is connected to the base and the bracket. When the push member moves in a first direction, it disengages from the bracket and drives the second charging terminal to move from the retracted position to the extended position. When the push member moves in a second direction, it pushes the bracket to compress the reset member. The first direction is opposite to the second direction.

[0009] Optionally, the number of the second charging terminals is two, the main body of the bracket is disposed in the first cavity, the first direction and the second direction are both perpendicular to the moving direction of the bracket, and the pushing member is disposed between the two brackets on the side that are close to each other.

[0010] Optionally, the drive assembly further includes a lead screw, which is connected to the output shaft of the drive unit. The pusher is sleeved on the lead screw, and the inner wall of the pusher is provided with an internal thread adapted to the lead screw. A first guide is provided in the first cavity, and a second guide is provided on the pusher. The first guide and the second guide are slidably engaged.

[0011] Optionally, the side end of the pusher is provided with a pusher portion, which protrudes toward the bracket. When the pusher portion abuts against the bracket, the second charging terminal is in the retracted position. The pusher can move to disengage from the bracket. After the bracket disengages from the pusher, the bracket abuts against the first guide member, and the second charging terminal is in the extended position.

[0012] Optionally, the first guide member includes a guide rod portion and a second clearance opening, the second guide portion is configured as a guide groove, the guide rod portion is engaged in the guide groove, and the pushing portion passes through the second clearance opening.

[0013] Optionally, the first cavity is provided with a third guide member, and the bracket is provided with a fourth guide portion, the third guide member and the fourth guide portion being slidably engaged; and / or at least one side of the second charging terminal is provided with a fifth guide portion, the second cavity is provided with a sixth guide member, the fifth guide portion and the sixth guide member being slidably engaged, the sixth guide member extending along the moving direction of the second charging terminal.

[0014] Secondly, this application proposes a cleaning system, including a cleaning device and the aforementioned charging base station, wherein the charging base station has a second charging terminal, and the cleaning device is provided with a first charging terminal adapted to the second charging terminal.

[0015] The technical solutions provided in this application have the following advantages compared with the prior art: The charging base station provided in this application allows the cleaning device to automatically move back into the accommodating space of the charging base station when it needs charging, or, if the cleaning device is a handheld device, the user can place it into the accommodating space and position it correctly. Before the cleaning device is in place, the second charging terminal is in a retracted position, completely within the second cavity, preventing it from protruding into the accommodating space and obstructing the movement path of the cleaning device, thus achieving avoidance of the cleaning device.

[0016] Once the cleaning equipment is in place, the drive assembly activates, moving the second charging terminal from its retracted position within the second cavity to its extended position. At this point, the second charging terminal precisely aligns with the first charging terminal of the cleaning equipment, establishing a stable electrical connection and activating the charging circuit within the charging base station to charge the cleaning equipment. Throughout this process, the second charging terminal remains stably in the extended position, ensuring consistent contact pressure with the first charging terminal and guaranteeing efficient charging of the cleaning equipment.

[0017] When the charging base station also includes a detection component and a control module, the detection component senses that the cleaning device is in the preset positioning position and sends a positioning signal to the control module, indicating that the cleaning device has arrived in place. Upon receiving the positioning signal, the control module sends a charging command to the drive component. When the cleaning device has finished charging, if the control module detects that the cleaning device is fully charged, or if the user triggers a pick-up / place-down command, the control module sends a reset signal to the drive component. The drive component then reverses its direction, causing the second charging terminal to retract from its extended position to its retracted position within the second cavity. At this point, the electrical connection between the cleaning device and the charging base station is disconnected, allowing the user to easily remove the cleaning device from the storage space, or the cleaning device to automatically leave the charging base station.

[0018] The charging base station provided in this application, when the second charging terminal is in the retracted position, is completely housed within the second cavity, thereby avoiding the movement path of the cleaning equipment within the accommodating space and ensuring that the cleaning equipment can be moved into place without damage to the second charging terminal. The cooperation of the detection component, control module, and drive component ensures that the timing of the second charging terminal's extension strictly matches the cleaning equipment's positioning, preventing premature or delayed extension and improving the docking success rate between the second and first charging terminals. Furthermore, the charging base station not only facilitates unobstructed placement and removal of the cleaning equipment but also enables proactive docking, simplifying user operation and enhancing the user experience.

[0019] Furthermore, the second charging terminal of this application only extends actively after the cleaning equipment is in place. If children or pets approach the charging base station or accidentally touch the corresponding area, the second charging terminal remains retracted and completely housed within the second cavity. This avoids the risk of electric shock from children touching the exposed second charging terminal out of curiosity, and also prevents damage or malfunction caused by pets' paws or fur accidentally touching the second charging terminal. Compared to lever-type trigger interfaces, the charging base station of this application significantly improves safety protection in idle states, making it suitable for various household use scenarios.

Detailed Implementation

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0029] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0030] The cleaning equipment applicable to the embodiments of this application includes handheld cleaning devices, robotic vacuum cleaners, robotic mops, handheld vacuum cleaners, and portable vehicle cleaning devices. Handheld cleaning devices can be handheld floor scrubbers.

[0031] like Figures 1-3 As shown, the charging base station according to an embodiment of this application includes: a base 90, a second charging terminal 41, and a driving component 10.

[0032] Specifically, the base 90 has a receiving space, and a first cavity is provided below the receiving space; a enclosure structure is provided on the side of the receiving space, which encloses and defines the receiving space, and a second cavity is provided inside the enclosure structure. The first cavity and the second cavity are connected, and a first clearance opening is provided on the side of the enclosure structure facing the receiving space; a second charging terminal 41 is movably disposed in the second cavity, and the second charging terminal 41 has an inward position in the second cavity and an outward position extending into the receiving space through the first clearance opening. When the second charging terminal 41 is in the outward position, it is used to electrically connect with the first charging terminal of the cleaning device placed in the receiving space; a drive assembly 10 is disposed in the first cavity or the second cavity, and the drive assembly 10 is drivenly connected to the second charging terminal 41 to drive the second charging terminal 41 to move between the inward position and the outward position.

[0033] The base 90 can be in the shape of a cuboid, cube, or other shape adapted to the bottom contour of the cleaning equipment. A accommodating space is located in the central area of ​​the upper surface of the base station to accommodate the bottom of the cleaning equipment. The accommodating space can be a square recess, with a guide ramp at the entrance. The cleaning equipment can move into the accommodating space through the entrance, and a second charging terminal is provided on at least one side of the direction of movement of the cleaning equipment.

[0034] If the charging base station is for single-sided charging, the second cavity can be located inside the left or right side of the accommodating space. If the charging base station is for dual-sided charging, two second cavities can be located on the left and right sides of the accommodating space. The drive assembly 10 can be located in the first cavity or in the second cavity. When the accommodating space has second charging terminals 41 on both sides, the drive assembly 10 can be located in the second cavity, so that a single drive unit 11 can be shared to provide power for the movement of the second charging terminals 41 on both sides.

[0035] The base 90 is typically composed of an upper housing and a lower housing connected by snap-fit ​​fasteners, which are used to fasten and secure the upper and lower housings after the relevant components are assembled. The upper housing defines an accommodating space, and the upper and lower housings together define a first cavity and a second cavity.

[0036] When the cleaning equipment is a handheld floor scrubber, the housing space is usually equipped with a limiting groove to position the wheels of the cleaning equipment.

[0037] The mounting body 40 of the second charging terminal 41 has a cuboid or cube structure, and the second charging terminal 41 includes 1 to 4 conductive pins. The second charging terminal 41 can be connected to the first charging terminal by either a contact type or a plug-in type.

[0038] The enclosure structure is provided with a first clearance opening, through which the second charging terminal 41 can be moved into the second cavity to be in a retracted position; or, through the first clearance opening, moved out of the second cavity to be in an extended position. The drive assembly 10 typically includes a drive unit 11, a pusher 12, and a transmission component that drives the drive unit 11 and the pusher 12. The drive unit 11 can be a drive motor, which can be fixed in the first cavity by a motor frame. In some embodiments, when the charging base station is provided with a first guide 60 to guide the pusher, the first guide 60 can also be integrated as a motor frame, providing both a fixing and limiting function for the drive unit 11 and a guiding function for the pusher 12. The tail of the first guide 60 can be provided with a motor mounting position.

[0039] If the transmission method of the transmission component and the pushing component 12 is screw drive, then the transmission component can be the screw 15, and the screw 15 can be directly connected to the output shaft of the drive motor through a coupling. In the transmission method of the transmission component and the pushing component 12, one end of the connecting rod is hinged to the output shaft of the drive motor, and the other end is hinged to the mounting body 40 of the second charging terminal 41.

[0040] The shape of the first clearance opening includes, but is not limited to, circles, squares, ovals, and polygons. Some first clearance openings may also have a sealing strip integrated at the edge of the opening.

[0041] A movable barrier can also be provided on the first clearance opening. The movable barrier can be driven by another set of power components. The shape of the movable barrier is usually adapted to the shape of the first clearance opening. In order to avoid the second charging terminal 41, the movable barrier usually slides along the extension direction of the side wall of the receiving space when exposing and blocking the first clearance opening, so as not to block the second charging terminal 41.

[0042] When the second charging terminal 41 is a pin type, if the second charging terminal 41 needs to be completely retracted into the second cavity, the mounting body 40 of the pin may have a certain gap with the first clearance opening. Therefore, an elastic protective member can be provided at the edge of the second charging terminal 41 and the first clearance opening. For example, the elastic protective member can be a flexible baffle made of rubber or silicone. The elastic protective member can be fixed to the circumferential edge of the first clearance opening near the second cavity by embedding or pasting. Moreover, the elastic protective member is perpendicular to the side wall of the accommodating space in its natural state. When the second charging terminal 41 is retracted, the elastic protective member can at least partially cover the gap between the mounting body 40 of the second charging terminal 41 and the first clearance opening. When the second charging terminal 41 is extended, the elastic protective member is compressed and does not affect the movement path of the second charging terminal 41.

[0043] In some embodiments, the charging base station further includes a detection component 80 and a control module 70. The detection component 80 is disposed on a base 90; the control module 70 is disposed on a base 90. The detection component 80 and the drive component 10 are communicatively connected. The detection component 80 is used to send an arrival signal to the control module 70 indicating that the cleaning equipment is in place. The control module 70 is configured to control the drive component 10 to operate according to the received arrival signal, so that the second charging terminal 41 moves from an inward position to an extended position.

[0044] The detection component 80 is used to detect whether the cleaning equipment has been moved into place. Only after the cleaning equipment has been fully moved into place can the second charging terminal 41 be accurately connected to the first charging terminal when it extends.

[0045] The detection assembly 80 may include at least one detection element, which may be disposed at different positions on the base 90, thereby enabling detection of the cleaning equipment at at least one position. For example, the detection element may be disposed in a first cavity, a second cavity, or a receiving space.

[0046] The detection element can be a photoelectric reflective sensor or a contact-type elastic touch sensor. When the cleaning device is moved into position, the corresponding part can squeeze the contact point to deform it, thereby triggering the detection element to send an arrival signal. In some embodiments, a Hall sensor can also be used. A magnetic component can be set at the bottom of the cleaning device. When the cleaning device is placed, the magnetic field strength reaches a preset value, and the Hall sensor will send an arrival signal to the control module 70.

[0047] When the detection element is disposed within the accommodating space, it can be positioned near a positioning protrusion or groove, or other limiting structure. In some embodiments, projected onto a horizontal plane, the detection element is positioned further away from the entrance of the accommodating space than the second charging terminal 41.

[0048] The detection component 80 is typically electrically connected to the control module 70, but in other embodiments it can also be wirelessly connected, such as via Bluetooth, Wi-Fi, or by having a built-in button battery.

[0049] The charging base station provided in this application allows the cleaning device to automatically move back into the accommodating space of the charging base station when it needs charging, or, if the cleaning device is a handheld device, the user can place it into the accommodating space and position it correctly. Before the cleaning device is in place, the second charging terminal 41 is in a retracted position, completely housed within the second cavity, preventing it from protruding into the accommodating space and obstructing the movement path of the cleaning device, thus achieving avoidance of the cleaning device.

[0050] The drive assembly 10 is activated, causing the second charging terminal 41 to move outward from its retracted position within the second cavity, eventually extending outward through the first clearance opening to its extended position. At this point, the second charging terminal 41 precisely aligns with the first charging terminal of the cleaning device, achieving a stable electrical connection and activating the charging circuit built into the charging base station to charge the cleaning device. Throughout this process, the second charging terminal 41 remains stably in its extended position, ensuring stable contact pressure with the first charging terminal and guaranteeing efficient charging of the cleaning device.

[0051] The activation of the drive unit 11 can be actively controlled, such as by triggering the control module 70 to activate the drive unit 11, or it can be automatically controlled, with the control module 70 detecting and controlling the activation of the drive unit 11 itself. For example, when the charging base station has a detection component 80, after the cleaning equipment is in place, the detection component 80 senses that the cleaning equipment is in a preset position and sends a position signal to the control module 70, indicating that the cleaning equipment is in place. After receiving the position signal, the control module 70 sends a charging command to the drive unit 10.

[0052] Once the cleaning device has finished charging, if the control module 70 detects that the cleaning device is fully charged, or if the user triggers a pick-up / place-down command, the control module 70 sends a reset signal to the drive component 10. The drive component 10 then reverses its operation, causing the second charging terminal 41 to retract from its extended position to its retracted position within the second cavity. At this point, the electrical connection between the cleaning device and the charging base station is disconnected, allowing the user to easily remove the cleaning device from the storage space, or the cleaning device to automatically leave the charging base station.

[0053] The charging base station provided in this application, when the second charging terminal 41 is in the retracted position, is completely housed within the second cavity, thereby avoiding the movement path of the cleaning equipment within the accommodating space and ensuring that the cleaning equipment can be moved into place without damage to the second charging terminal 41. The cooperation of the detection component 80, the control module 70, and the drive component 10 ensures that the timing of the extension of the second charging terminal 41 is strictly matched with the positioning state of the cleaning equipment, avoiding premature or delayed extension and improving the success rate of docking between the second charging terminal 41 and the first charging terminal.

[0054] Secondly, the charging base station not only facilitates the unobstructed placement and retrieval of cleaning equipment but also enables proactive docking, simplifying user operation and enhancing the user experience. Furthermore, the second charging terminal 41 of this application only extends actively after the cleaning equipment is in place. If children or pets approach the charging base station or accidentally touch the corresponding area, the second charging terminal 41 remains retracted and completely housed within the second cavity. This avoids the risk of electric shock from children touching the exposed second charging terminal 41 out of curiosity, and also prevents damage or malfunction caused by pets' paws or fur accidentally touching the second charging terminal 41. Compared to lever-type trigger interfaces, the charging base station of this application significantly improves safety protection in idle states, making it suitable for various household use scenarios.

[0055] like Figure 1 and Figure 3 As shown, the charging base station according to the embodiment of this application also includes a bracket 30, on which a second charging terminal 41 is provided. The driving assembly 10 includes a driving part 11 and a pushing member 12, which are connected in a transmission manner. When the charging base station has a control module, the driving part 11 is connected in a communication manner with the control module 70. When the driving part 11 is running, it drives the pushing member 12 to move so that the bracket 30 drives the second charging terminal 41 to move from the retracted position to the extended position.

[0056] like Figure 1 , Figure 4 and Figure 5 As shown, the bracket 30 typically includes a first sub-part 31 and a second sub-part 32 that are connected to each other. The first sub-part 31 directly supports the mounting body 40, which is provided with the second charging terminal 41.

[0057] The bracket 30 can be elongated; or the bracket 30 can include a first sub-part 31 and a second sub-part 32, which are connected and form an L-shape, wherein both the first sub-part 31 and the second sub-part 32 are plate-shaped. The mounting body 40 of the second charging terminal 41 can be fixed to the bracket 30 by threaded connection, embedded adhesive, etc. The force-bearing end of the bracket 30 is directly opposite the force-applying end of the push member 12, that is, the end of the second sub-part 32 away from the first sub-part 31 is the force-bearing end. The force-bearing end of the bracket 30 and the force-applying end of the push member 12 are usually in contact. Normally, the force-applying end of the push member 12 is located on the side of the push member 12, or other transmission components are provided between the push member 12 and the drive unit 11, so that the moving direction of the push member 12 can be the same as the moving direction of the bracket 30.

[0058] The drive assembly 10 is disposed in the first cavity, and the main body of the bracket 30 is disposed in the first cavity. That is, the first sub-part 31 is located in the second cavity, and the second sub-part 32 is located in the first cavity. The second sub-part 32 typically extends along the width direction of the accommodating space, that is, perpendicular to the direction of movement of the cleaning device.

[0059] When the detection component 80 sends a signal to the control module 70 indicating that the cleaning equipment is in place, the control module 70 sends a first operating command to the drive unit 11. The drive unit 11 then starts and moves the push member 12. Due to the cooperation between the push member 12 and the bracket 30, after the push member 12 moves, the bracket 30 will move the second charging terminal 41 from the retracted position to the extended position, thereby achieving docking with the first charging terminal of the cleaning equipment.

[0060] According to the charging base station of this application embodiment, the bracket 30 can provide a stable carrier for the movement of the second charging terminal 41. Simultaneously, through cooperation with the pusher 12, it can drive the movement of the second charging terminal 41, preventing the pusher 12 from directly acting on the second charging terminal 41. Furthermore, by changing the length of the bracket 30, the cooperation area between the bracket 30 and the pusher 12 can be positioned further away from the second charging terminal 41, allowing the drive assembly 10 to be positioned as needed, thus improving layout flexibility.

[0061] like Figure 2 and Figure 5 As shown, in some embodiments, the charging base station further includes a reset member 20, which is connected to the base 90 and the bracket 30. When the push member 12 moves along the first direction, it disengages from the bracket 30, and the reset member 20 drives the second charging terminal 41 to move from the retracted position to the extended position. When the push member 12 moves along the second direction, it pushes the bracket 30 to compress the reset member 20. The first direction is opposite to the second direction.

[0062] The reset element 20 can be a spring or an elastic sheet, etc. The base 90 has a pre-set fixing structure, such as a slot or a connecting lug with a screw hole, and the bracket 30 also has a mounting groove that mates with the reset element 20.

[0063] When the cleaning equipment is not in position, the second charging terminal 41 is in the retracted position, the pushing member 12 pushes against the bracket 30, and the reset member 20 is compressed by the bracket 30 due to the push. After the cleaning equipment moves into position, the detection component 80 sends a position signal to the control module 70. The control module 70 drives the drive unit 11 to move the pushing member 12 in the first direction, causing the pushing member 12 to disengage from the bracket 30. Since the reset member 20 connects the base 90 and the bracket 30, after the pushing member 12 disengages from the bracket 30, the reset member 20 is released, causing the bracket 30 to move towards the pushing member 12, thereby causing the second charging terminal 41 fixed on the bracket 30 to move from the retracted position to the extended position, and finally extend into the receiving space to achieve precise docking with the first charging terminal of the cleaning equipment.

[0064] When it is necessary to drive the second charging terminal 41 to retract in order to avoid the cleaning equipment leaving or to reset after charging is completed, the control module 70 controls the drive unit 11 to drive the push member 12 to move in the second direction. The push member 12 pushes against the bracket 30, and the bracket 30 is forced to compress the reset member 20, thereby moving and driving the second charging terminal 41 to retract from the extended position to the retracted position in the second cavity.

[0065] According to the charging base station of this application embodiment, after the pusher 12 disengages from the bracket 30, the bracket 30 uses the reset spring force of the reset member 20 to eject the second charging terminal 41 from the second cavity to the extended position. Due to the elasticity of the reset member 20, it has an adaptive effect, and the second charging terminal 41 can be buffered when it comes into contact with an obstacle, especially when it comes into contact with the first charging terminal, which can effectively buffer wear and avoid excessive impact. In addition, the reset member 20 provides appropriate resistance force for the second charging terminal 41 and the first charging terminal, thereby ensuring that the two are always in an effective electrical contact state, avoiding poor connection and damage caused by excessive connection pressure.

[0066] In some embodiments, a buffer spring 43 may be provided on the second charging terminal 41 to further ensure that the second charging terminal 41 can be effectively electrically connected to the first charging terminal and maintain appropriate resistance. A guide post 42 is also provided on the bracket 30, and the buffer spring 43 is sleeved on the guide post 42, thereby limiting the deformation direction of the spring through the guide post 42.

[0067] like Figure 2 and Figure 5As shown, in some examples, the rear end of the pin can also be used as a guide post 42 to improve the docking accuracy between the second charging terminal 41 and the first charging terminal, while simplifying the structural setup.

[0068] like Figure 3 As shown, in some embodiments, both the first direction and the second direction are perpendicular to the direction of movement of the bracket 30.

[0069] The direction of movement of the bracket 30 is the same as the direction of movement of the second charging terminal 41. If the second charging terminal 41 moves horizontally, then both the first and second directions are horizontal and opposite to the direction of movement of the bracket 30.

[0070] When it is necessary to drive the second charging terminal 41 from the extended position to the retracted position, the control module 70 controls the drive unit 11 to drive the push member 12 to move along the second direction. The push member 12 applies a pushing force to the bracket 30, causing the bracket 30 to compress the reset member 20 until the second charging terminal 41 is in the retracted position.

[0071] After the cleaning equipment is in place, the second charging terminal 41 needs to be extended. The control module 70 controls the drive unit 11 to operate, driving the pusher 12 to move along the first direction. After the pusher 12 disengages from the bracket 30, the reset member 20 pushes the bracket 30 to move under the action of elasticity, driving the second charging terminal 41 from the retracted position to the extended position.

[0072] If the pushing member 12 moves directly toward the bracket 30 to push against the bracket 30, assembly errors could easily cause the bracket 30 to tilt or jam. Furthermore, the magnitude of this pushing force directly affects the clamping force between the second charging terminal 41 and the first charging terminal. However, in the charging base station of this embodiment, both the first and second directions are perpendicular to the moving direction of the bracket 30. The pushing member 12 only controls the bracket 30 to compress and release the reset member 20, thus extending and retracting the second charging terminal 41.

[0073] like Figure 4 and Figure 5 As shown, in the charging base station according to the embodiment of this application, a third guide member 50 is provided in the first cavity, and a fourth guide part is provided on the bracket 30. The third guide member 50 and the fourth guide part are slidably engaged.

[0074] The third guide 50 and the second guide both extend along the moving direction of the second charging terminal 41. In some embodiments, the extending directions of the third guide 50 and the second guide are perpendicular to the first direction and the second direction.

[0075] The third guide member 50 can be a guide rail or a guide post. The cross-sectional shape of the guide post can be circular, square, or prismatic. Of course, the third guide member 50 can also be set as a guide groove with the opening facing upward, and the cross-section can be U-shaped or C-shaped.

[0076] The fourth guide portion is a structure on the bracket 30 that mates with the third guide member 50; therefore, its structural features match those of the third guide member 50. The fourth guide portion can be a slider-like structure and can be relatively short; alternatively, the length of the fourth guide portion can be approximately equal to the length of the third guide member 50, thus increasing the contact area between the fourth guide portion and the third guide member 50 during the sliding process of the bracket 30, resulting in higher guiding accuracy. Alternatively, the fourth guide portion can also be a bushing-like structure that mates with a guide post; or it can be a guide protrusion structure that can be adapted to a guide groove.

[0077] The fourth guide portion is positioned corresponding to the third guide member 50, and is directly formed or fixed to the corresponding surface of the bracket 30 to ensure precise fit with the third guide member 50. For example, if the third guide member 50 is located on both sides of the bracket 30, the fourth guide portion is also located on both sides of the bracket 30; if the third guide member 50 is located at the bottom of the bracket 30, the fourth guide portion is also located at the bottom of the bracket 30.

[0078] The sliding cooperation between the third guide member 50 and the fourth guide member provides precise directional constraints for the movement of the bracket 30, preventing the bracket 30 from shifting or tilting under the pushing force of the reset member 20 or the pushing member 12; ensuring that the second charging terminal 41 always extends and retracts along the preset trajectory, thereby reducing the possibility of misalignment between the second charging terminal 41 and the first charging terminal.

[0079] Of course, in some embodiments, the bracket 30 does not have an additional guide structure. Instead, the side end face is used as the fourth guide part to cooperate with the third guide member 50. The third guide member 50 includes two oppositely arranged side plate-shaped guide rails. The bracket 30 is slidably disposed therein and is slidably cooperated with the third guide member 50 through the side end face.

[0080] In some embodiments, the force-bearing end of the second sub-part 32 of the bracket 30 can also be connected to a third sub-part 33. The extension direction of the third sub-part 33 is parallel to the extension direction of the first sub-part 31, but opposite to the extension direction of the first sub-part 31. In this way, without increasing the weight of the bracket 30 to avoid insufficient thrust of the reset member 20, the contact area between the bracket 30 and the push member 12 is increased through the contact engagement of the third sub-part 33 and the push member 12, thereby ensuring stable follow-up when the bracket 30 is driven, and indirectly ensuring the docking accuracy of the second charging terminal 41.

[0081] In some embodiments, to further improve the docking accuracy between the second charging terminal 41 and the first charging terminal, a fifth guide portion 44 is provided on at least one side of the second charging terminal 41, and a sixth guide member is provided in the second cavity, with the fifth guide portion 44 slidably engaged in the sixth guide member. The fifth guide portion 44 is protruding, and the sixth guide member extends along the moving direction of the second charging terminal.

[0082] like Figure 1 and Figure 4 As shown, in some embodiments, the number of second charging terminals 41 is two. The main body of the stent 30 is disposed in the first cavity. When the stent 30 has a second sub-part 32, the main body of the stent 30 is the second sub-part 32.

[0083] There are two second charging terminals 41, each including at least one pin. The second charging terminal 41 on one side of the accommodating space may include a pin as the positive terminal, and the second charging terminal 41 on the other side of the accommodating space may include a pin as the negative terminal. This reduces the risk of short circuits between the positive and negative pins, and reduces the possibility of accidental conduction between the two poles due to dust, moisture, or metal debris, thus improving charging safety. One of the second charging terminals 41 may also be equipped with a first signal pin, and the first charging terminals on both sides of the cleaning device are respectively equipped with matching second signal pins and power pins. After the cleaning device moves into place in the accommodating space, the drive assembly 10 drives the two second charging terminals 41 to extend synchronously through the first clearance opening, thereby forming a complete charging circuit with the power pin of the cleaning device to charge the cleaning device. The first signal pin of the second charging terminal 41 contacts the second signal pin of the first charging terminal, enabling the charging base station to establish communication with the cleaning equipment. This allows the base station to send reminder commands to the cleaning equipment, such as charging in progress or charging completed. This eliminates the need for additional signal ports in the charging base station, improving the stability and intelligence of the charging process.

[0084] like Figure 3 and Figure 6 As shown, in some embodiments, the drive assembly 10 further includes a lead screw 15, which is connected to the output shaft of the drive unit 11. A pusher 12 is sleeved on the lead screw 15, and the inner wall of the pusher 12 is provided with an internal thread that is adapted to the lead screw 15.

[0085] Figure 2 The first direction and the second direction are shown in the figure, which are along the extension direction of the lead screw 15.

[0086] When the cleaning equipment is not in place, the drive unit 11 is in standby mode, the lead screw 15 remains stationary, and the pusher 12 sleeved on the lead screw 15 is fixed in a preset position because its inner wall thread is adapted to the lead screw 15. At this time, the pusher part 13 of the pusher 12 abuts against the ends of the two brackets 30, forcing the brackets 30 to drive the second charging terminal 41 to the retracted position. When the cleaning equipment is in place, the detection component 80 sends a position signal to the control module 70, and the control module 70 controls the drive unit 11 to run. The output shaft of the drive unit 11 drives the lead screw 15 to rotate. Since the inner wall thread of the pusher 12 is engaged with the thread of the lead screw 15, the rotational motion of the lead screw 15 is converted into the linear motion of the pusher 12 along the axis of the lead screw 15. By moving the pusher 12 along the first direction, the reset member 20 is released, and the bracket 30, under the action of the elastic force of the reset member 20, drives the second charging terminal 41 to extend from the first clearance opening. If the second charging terminal 41 needs to retract, the output shaft of the drive unit 11 changes its rotation direction, causing the lead screw 15 to rotate in the opposite direction, the pusher 12 moves along the second direction, the pusher 13 re-abuts against the bracket 30 and pushes the bracket 30 to compress the reset member 20, so that the second charging terminal 41 retracts to the inward position.

[0087] According to the charging base station of this application embodiment, the pusher 12 and the lead screw 15 are connected by a threaded transmission, enabling precise motion control and thus accurately adjusting the extension stroke of the bracket 30 and the second charging terminal 41. This avoids deviations in docking caused by excessive or insufficient extension of the second charging terminal 41, significantly improving the docking accuracy with the first charging terminal. Simultaneously, the threaded connection between the pusher 12 and the lead screw 15 is self-locking, preventing displacement due to the reaction force of the bracket 30 or external vibrations. This ensures the positional stability of the second charging terminal 41 when extending to dock with the first charging terminal or retracting to avoid it, preventing charging interruptions or interference with cleaning equipment due to displacement of the second charging terminal 41. The threaded connection structure of the pusher 12 and the lead screw 15 is simple, wear-resistant, and suitable for long-term use, reducing user maintenance costs.

[0088] like Figure 3 and Figure 6 As shown, in some embodiments, the side end of the pusher 12 is provided with a pusher portion 13, which protrudes toward the bracket 30. When the pusher portion 13 abuts against the bracket 30, the second charging terminal 41 is in the retracted position. The pusher 12 can be moved to disengage from the bracket 30. After the bracket 30 disengages from the pusher 12, the bracket 30 abuts against the first guide member 60, and the second charging terminal 41 is in the extended position.

[0089] The pusher 12 is located on the side of the two supports 30 that are close to each other. When the cleaning device is not in place, the pusher part 13 of the pusher 12 abuts against the inner sidewall of the two supports 30, which will exert an outward pushing force on the supports 30 on both sides, forcing the two supports 30 to move in a direction away from each other, and causing the second charging terminal 41 to retract to the inside of the first clearance opening and be in the retracted position.

[0090] Once the cleaning equipment is in place, the detection component 80 sends a positioning signal to the control module 70, which then drives the pusher 12 to move. Since the pusher 12 has moved to avoid the obstruction, the first guide 60 and the bracket 30 are positioned opposite each other. Under the elastic force of the reset component 20, the two brackets 30 move towards each other, causing them to abut against the first guide 60. This causes the second charging terminal 41 to extend through the first clearance opening and finally reach the extended position, connecting with the first charging terminal. When the second charging terminal 41 needs to retract, the pusher 12 moves in the opposite direction, and the pusher 13 abuts against the bracket 30 again, repeating the above process.

[0091] According to the charging base station of this application embodiment, the movement of the same pusher 12 can drive the two second charging terminals 41 to move, reducing the number of drive components 10, ensuring that the extension and retraction of the second charging terminals 41 on both sides are synchronized, and avoiding the second charging terminal 41 on one side extending lagging behind.

[0092] like Figure 3 and Figure 6 As shown, in the charging base station according to the embodiment of this application, a first guide member 60 is also provided in the first cavity, and a second guide portion 14 is provided on the push member 12, with the first guide member 60 and the second guide portion 14 slidingly engaged.

[0093] The second guide portion 14 is disposed on the side end of the push member 12 and is configured as a guide groove. The push member 12 is also provided with a push portion 13 protruding from the side of the push member 12. The push portion 13 can be located above or below the second guide portion 14. The first guide member 60 includes two guide rod portions 61 and a second clearance opening 62 disposed above or below the guide rod portions 61. The guide rod portions 61 are engaged in the guide groove, and the push portion 13 passes through the second clearance opening 62. In this way, the push member 12 is clamped in the middle by the guide rod portions 61 on both sides, and the push portion 13 extends through the second clearance opening 62 to abut against the bracket 30. When the bracket 30 has a third sub-part 33, the push portion 13 abuts against the third sub-part 33. When the guide rod part 61 is above the second clearance opening 62, the second guide part 14 is positioned above the pushing part 13. When the guide rod part 61 is positioned below the second clearance opening 62, the second guide part 14 is positioned below the pushing part 13.

[0094] In a specific example of this application, the guide rod 61 is positioned above the second clearance opening 62, which can also limit the upper limit of the pushing member 12, thereby further improving the movement accuracy of the pushing member 12.

[0095] To save on the number of parts, the tail of the first guide member 60 also has a motor mounting position, in which the drive unit 11 is also fixed, thereby achieving the installation and fixation of the drive unit 11.

[0096] The first guide member 60 and the second guide part 14 slide together, which can effectively limit the degree of freedom of movement of the push member 12, ensure that the push member 12 can only move along the extension axis of the lead screw 15, ensure the stability and accuracy of the push member 12's thrust on the bracket 30, and improve the transmission efficiency of the drive assembly 10.

[0097] The cleaning system according to the embodiments of this application includes a cleaning device and the above-mentioned charging base station. The charging base station has a second charging terminal 41, and the cleaning device is provided with a first charging terminal adapted to the second charging terminal 41.

[0098] According to the cleaning system of this application embodiment, when the second charging terminal 41 of the charging base station is in the retracted position, it is completely housed within the second cavity, thereby avoiding the movement path of the cleaning device within the accommodating space and ensuring that the cleaning device can be moved into place without damage to the second charging terminal 41. The cooperation of the detection component 80, the control module 70, and the drive component 10 ensures that the extension timing of the second charging terminal 41 strictly matches the positioning state of the cleaning device, avoiding premature or delayed extension and improving the docking success rate between the second charging terminal 41 and the first charging terminal. Secondly, the charging base station can both facilitate the unobstructed placement and removal of the cleaning device and enable active docking, simplifying user operation and improving the user experience. In addition, the second charging terminal 41 of this application will only actively extend after the cleaning device is in place. If children or pets approach the charging base station or accidentally touch the corresponding area of ​​the charging base station, the second charging terminal 41 will always be in a retracted position and completely housed within the second cavity. This avoids the risk of electric shock caused by children touching the exposed second charging terminal 41 out of curiosity, and also prevents damage or malfunction caused by pets' paws, hair, etc., accidentally touching the second charging terminal 41. Compared to lever-type trigger terminals, the charging base station of this application embodiment significantly improves safety protection capabilities in the idle state, making it suitable for home use in various scenarios.
