[0046] The embodiments of the present application provide a charging device 10, a cleaning base station and a cleaning system, wherein the charging device 10 and the base body 20 cooperate to form the cleaning base station, and the cleaning base station and the cleaning host cooperate to form the cleaning system. The cleaning system has the cleaning base station with the charging device 10, and also has a cleaning host with a rolling brush and / or a mop cloth and the like. The cleaning system can be a mopping robot, a sweeping and mopping robot or a scrubber, etc. with a base station and capable of realizing the mopping function, and the corresponding cleaning host is a mopping robot host, a sweeping and mopping robot host and a scrubber host, etc. The cleaning host has the sweeping and / or mopping function. It can be understood that the cleaning host is provided with a charging component for charging, such as a contact point, etc. When the cleaning host is located in the accommodating cavity 220 of the cleaning base station, the charging device 10 located on the cleaning base station can be electrically connected with the charging component on the cleaning host, so as to realize the charging of the cleaning host.

[0047] The cleaning host can be a device that automatically performs cleaning operations in a certain area to be cleaned. The cleaning base station is at least used to charge the cleaning host. For example, when the cleaning host starts working, the cleaning host can start from the cleaning base station and perform a corresponding cleaning task; when the cleaning host completes the cleaning task or needs to be charged, the cleaning host can return to the cleaning base station for charging. Of course, the cleaning base station can also provide the cleaning host with other maintenance functions in addition to charging, such as washing the mop on the cleaning host, charging, water replenishment, dust collection, and the like. When the cleaning host starts working, the cleaning host can start from the cleaning base station and perform a corresponding cleaning task; when the cleaning host completes the cleaning task or other situations that need to suspend the cleaning task, the cleaning host can return to the cleaning base station for at least one or more of charging, water replenishment, washing, dust collection, and the like.

[0048] The cleaning base station includes a base station body 20 and a charging device 10, wherein the base station host has a mounting seat 210 and a containing cavity 220 for accommodating the cleaning host, and the charging device 10 is mounted on the mounting seat 210 and can move relative to the containing cavity 220 between a first position and a second position. When the cleaning host moves into the containing cavity of the base station body 20, an external force can be applied to the charging device 10 so that the charging device 10 moves from the first position to the second position. When the charging device 10 moves to the second position, the charging device 10 can be electrically connected with the charging part of the cleaning host to charge the cleaning host.

[0050] Please refer to Figure 1 The embodiment of the present application provides a charging device 10, which can be used to be installed on a cleaning base station to charge a cleaning host matched with the cleaning base station.

[0051] Specifically, the charging device 10 includes a charging component 1 and an elastic element 2. The charging component 1 can be movably installed at the desired installation position. The elastic element 2 includes a fixed end 201 and a follower end 202. The fixed end 201 is fixedly installed relative to the moving end of the charging component 1, and the follower end 202 is disposed on the charging component 1 and can move synchronously with the movement of the charging component 1. When the charging component 1 is driven by an external force and moves, the follower end 202 of the elastic element 2 moves synchronously and undergoes elastic deformation during this process. When the external force is removed, the elastic element 2 returns to its original shape and can drive the charging component 1 to move to the initial position.

[0052] In some embodiments, the charging component 1 can be mounted on the installation position via the movable shaft 3.

[0053] In some embodiments, the elastic element 2 may be a torsion spring structure, such as... Figure 1 As shown. The torsion spring includes a spring body 21, a fixed torsion arm 22 and a follower torsion arm 23, wherein the fixed torsion arm 22 has the aforementioned fixed end 201, the follower torsion arm 23 has the aforementioned follower end 202, and the spring body 21 can be sleeved on the aforementioned movable shaft 3.

[0054] Please see Figure 1 The spring body 21 is connected to the moving shaft 3, the follower torsion arm 23 is connected to the charging component 1, and the fixed torsion arm 22 is fixedly installed relative to the moving shaft 3. Under the drive of an external force, the charging component 1 moves from the first position to the second position, and in this process, it drives the follower torsion arm 23 to move synchronously and approach the fixed torsion arm 22. At this time, the spring body 21 undergoes elastic deformation. When the external force is removed, the spring body 21 can return to its initial shape under the action of elasticity. At this time, the follower torsion arm 23 can drive the charging component 1 back to the initial position, i.e., the first position.

[0055] It should be noted that, along the axial direction of the torsion spring (that is, along the axial direction of the spring body 21), the projection of the fixed torsion arm 22 and the projection of the follower torsion arm 23 do not intersect, and their orthogonal projections along the axial direction of the torsion spring are spaced apart. In other words, the fixed torsion arm 22 and the follower torsion arm 23 are located on both sides of the spring body 21.

[0056] When the size of the charging device 10 needs to be adjusted, only the size of the moving arm of the charging component 1 needs to be adjusted, and the specifications of the torsion spring need to be adjusted accordingly to allow the charging component 1 to move normally. Compared with related structures, the charging device 10 provided in this embodiment is more flexible in size range. When the installation space of the charging device 10 is limited, this embodiment can achieve miniaturization of the charging device 10 by shortening the moving arm of the charging component 1 without changing the basic shape of the elastic element 2, thereby reducing the space occupation of the charging device 10 in the clean base station.

[0057] When the charging assembly 1 is installed on the mounting seat 210 of the cleaning base station, please refer to Figure 2 . The cleaning base station is between the first position and the second position.

[0058] The fixed torsion arm 22 and the follow-up torsion arm 23 of the torsion spring are L-shaped or similar L-shaped structures. In the axial projection direction of the moving shaft 3, please refer to Figure 2 , the projection of the part where the fixed torsion arm 22 is connected to the spring body 21 and the part where the follow-up torsion arm 23 is connected to the spring body 21 in the direction has an included angle, and the included angle is acute.

[0059] Specifically, the angle range of the above-mentioned included angle can be 60°-85°, and the specific value can be adaptively adjusted within the range according to design needs. For example, the included angle can take any value in the values of 60°, 65°, 70°, 75°, 80°, and 85°.

[0060] Please refer to Figures 1-2 , it can be seen that when the charging device 10 is installed on the mounting seat 210, the moving shaft 3 and the fixed torsion arm 22 of the torsion spring are located at the fixed position of the mounting seat 210, and there is a certain interval between the moving shaft 3 and the fixed torsion spring, and the moving end of the charging assembly 1 can be connected with the moving shaft 3 by being sleeved on the moving shaft 3. When the charging assembly 1 is extruded by external force and moves towards the second position, the included angle formed between the fixed torsion arm 22 and the follow-up torsion arm 23 gradually decreases.

[0061] The structure of the charging device 10 will be further described below:

[0062] Please refer to Figure 3 , the charging device 10 includes a charging assembly 1, a moving shaft 3, and a torsion spring, wherein the charging assembly 1 includes a detachably connected moving bracket 11 and a conductive sheet 12, wherein the moving bracket 11 is formed with an angle, and the overall structure is similar to L-shaped or T-shaped, and the follow-up swing arm of the torsion spring is connected with the moving bracket 11.

[0063] Specifically, please refer to Figure 3 , the end of the follow-up swing arm of the torsion spring is bent to form a corner, and the moving bracket 11 is provided with a limiting perforation 1112 for installing the follow-up swing arm. When the torsion spring is connected with the moving bracket 11, please refer to Figure 1 , at this time, the follow-up swing arm is inserted into the limiting perforation 1112, and the corner part of the follow-up swing arm can be exposed relative to the limiting perforation 1112, so as to realize the firm fixation of the follow-up swing arm and the limiting perforation 1112. The corner structure cooperates with the limiting perforation 1112, which helps to avoid the possibility of being separated from the moving bracket 11 under the action force of the elastic deformation of the torsion spring.

[0064] In the embodiment or other similar embodiments, the mobile support 11 can be an integral structure or a split structure.

[0065] Referring to Figures 4-5 The mobile support 11 comprises a mobile part 111 and an abutting part 112 connected to each other, one end of the mobile part 111 away from the abutting part 112 is connected to the mounting seat 210 through the mobile shaft 3, the follower end 202 is arranged on the mobile part 111, and the conductive sheet 12 is arranged on the abutting part 112.

[0066] Specifically, the mobile part 111 is provided with a shaft hole 1111, and the mobile shaft 3 is arranged in the shaft hole 1111; or in other words, the mobile part 111 is sleeved on the mobile shaft 3 through the shaft hole 1111 to be installed on the mounting seat 210. In addition, the limiting perforation 1112 is also arranged on the mobile part 111, and the follower torsion arm 23 is connected to the mobile shaft 3 through the limiting perforation 1112.

[0067] Referring to Figure 5 Although the mobile part 111 and the abutting part 112 are connected through the folding angle structure and extend in different directions respectively, they are basically in a vertical or substantially vertical state.

[0068] The internal space of the cleaning base station is limited, and the positions of various components and the space ratios occupied by the components need to be reasonably arranged according to the design requirements, and the components cannot interfere with each other. In order to achieve this purpose, the size and space ratio of the charging device 10 for charging the cleaning host are also limited by the internal space layout of the cleaning base station, and the charging device 10 also affects the arrangement of other components. In order to reduce the space ratio of the charging device 10 in the cleaning base station and at the same time realize the compactness and miniaturization improvement of the cleaning base station as much as possible, it is necessary to further optimize the structure of the charging device 10 to meet the design requirements of the cleaning base station.

[0069] Based on the above purpose, the charging device 10 provided by the embodiment of the application can shorten the swing arm size to a suitable length as needed.

[0070] Since the abutting part 112 is used to cooperate with the conductive sheet 12 to realize the charging function of the charging device 10, the size of the abutting part 112 part is basically unchanged, and since the swing arm size of the charging assembly 1 is mainly affected by the length of the mobile part 111, under this premise, in order to shorten the swing arm size, the size of the mobile part 111 can be adjusted within a certain range as needed.

[0071] Specifically, the smaller the length of the mobile part 111, the smaller the swing arm of the charging device 10, and the smaller the overall size of the charging device 10. Correspondingly, the space ratio of the charging device 10 in the cleaning base station is also smaller.

[0072] In some embodiments, the length ratio of the moving part 111 and the abutting part 112 can be set to 0.8-1.2. This range of values can effectively reduce the space occupied by the charging device 10 installed on the cleaning base station without affecting the normal charging function of the charging device 10.

[0073] The conductive sheet 12 is in the shape of a U or similar, as shown in Figures 4-5 .

[0074] Specifically, the conductive sheet 12 is arranged at the end of the abutting part 112 away from the moving part 111, and includes a first connecting part 122, a contact part 121, and a second connecting part 123 connected in sequence. The contact part 121 is located at the free end of the abutting part 112, i.e., the side of the abutting part 112 facing away from the second position. The first connecting part 122 and the second connecting part 123 are respectively connected to the two side edges of the contact part 121 opposite to the contact part 121. At this time, the first connecting part 122 and the second connecting part 123 are oppositely arranged and form a space for inserting the abutting part 112 between them.

[0075] In some embodiments, the contact part 121, the first connecting part 122, and the second connecting part 123 are in an integrated structure and are formed by bending to constitute the conductive sheet 12.

[0076] As shown in Figure 5 , the end of the first connecting part 122 and the second connecting part 123 away from the contact part 121 is provided with a buckle 124, and the surface of the abutting part 112 is recessed with a clamping groove 114 matched with the buckle 124. When the conductive sheet 12 is sleeved on the abutting part 112, the buckle 124 can be elastically deformed and inserted into the clamping groove 114, realizing the firm combination of the conductive sheet 12 and the abutting part 112.

[0077] The buckle 124 and the clamping groove 114 can effectively improve the firmness of the combination of the conductive sheet 12 and the abutting part 112, and reduce the possibility of the conductive sheet 12 being separated from the abutting part 112 under the action of external force.

[0078] When the cleaning host enters the accommodating cavity 220 of the cleaning base station, the abutting portion 112 provided with the conductive sheet 12 can be in contact with the cleaning host and move from the first position to the second position under the continuous pushing force provided by the cleaning host. During the movement, the abutting portion 112 is pulled by the moving portion 111, and the torsion spring connected to the moving portion 111 provides a continuous pressure to the abutting portion 112 and the contact portion 121 on the abutting portion 112 through the moving portion 111 during the movement, so that the contact portion 121 outside the abutting portion 112 can maintain a close abutting state with the outer wall of the cleaning host. That is, the contact portion 121 can always follow the movement of the cleaning host and abut against the outer wall of the cleaning host under the elastic force provided by the torsion spring, and the two can maintain a stable contact state.

[0079] When the cleaning host is in place, the abutting portion 112 moves to the second position and maintains a stable contact state with the cleaning host. The cleaning host realizes stable contact with the contact portion 121 provided on the abutting portion 112 through the charging component (which can be a contact with a conductive function or other related technology disclosed structure with a conductive function), and realizes circuit conduction. At this time, the cleaning base station in the energized state can supply power to the cleaning host.

[0080] The structure of the conductive sheet 12 will be described in detail below.

[0081] Referring to Figure 5 The conductive sheet 12 can be connected to the cleaning host through the contact portion 121. Therefore, the contact portion 121 is provided with a charging contact 1211, and the number of the charging contact 1211 is at least one, and any one of the charging contact 1211 is protruded from the surface of the contact portion 121 and forms a contact surface 1212.

[0082] Referring to Figure 1 and Figure 5 The charging contact 1211 is a strip structure, and the extension direction of the charging contact 1211 is basically consistent with the axial direction of the moving shaft 3.

[0083] Specifically, the contact portion 121 is provided with two charging contacts 1211.

[0084] The surface of the charging contact 1211 can be a smooth curved surface. In some embodiments, part of the surface of the contact portion can be a flat surface, for example, the contact surface 1212 can be a flat surface.

[0085] Referring to Figure 5 It can be seen by observation that the contact surface 1212 is inclined with respect to the surface of the contact portion 121.

[0086] In view of the fact that the cleaning host located in the accommodating cavity 220 of the cleaning base station is inclined relative to the ground, the contact surface 1212 for electrical connection with the cleaning host is designed as an inclined surface, which can make the contact area of the charging contact 1211 and the contact part 121 of the conductive part of the cleaning host larger, and make the contact part 121 of the two more closely and firmly, thereby reducing the probability of poor contact. In addition, since the actual position and the inclination angle of the cleaning host may deviate to a certain extent each time it enters the accommodating cavity 220, the inclined charging contact 1211 can better adapt to this inaccurate docking condition, and can allow a certain angular deviation and positional deviation between the cleaning host and the charging device 10 within a certain range, so as to ensure the success rate of electrical connection between the cleaning host and the charging device 10.

[0087] Since the position and angle of the cleaning host entering the cleaning base station each time may have slight differences, which affects the success rate of alignment between the cleaning host and the charging device 10. In order to solve this problem and reduce the probability of failure of the cleaning host due to misalignment, in some embodiments, at least two charging devices 10 described above can be arranged in the cleaning base station, and the charging devices 10 are arranged symmetrically left and right relative to the accommodating cavity 220 in the cleaning base station.

[0088] The left and right symmetrically arranged charging devices 10 can play a certain guiding role in the process of the cleaning host entering the accommodating cavity 220, and can also ensure the stability and efficiency of charging to a certain extent.

[0089] Since the charging contact 1211 is arranged inclined relative to the surface of the contact part 121, when the number of charging devices 10 is two and arranged symmetrically left and right, the corresponding conductive sheet 12 detachably connected with the moving bracket 11 also has two different structures arranged symmetrically. When assembling the charging device 10, the conductive sheet 12 and the moving bracket 11 need to be assembled one by one according to the different installation positions, so as to avoid the situation that the charging contact 1211 is installed in reverse.

[0090] In order to further reduce the assembly difficulty of the charging contact 1211, in some embodiments, a foolproof design can be added to the above-mentioned charging assembly 1.

[0091] In some embodiments, the foolproof design includes a positioning protrusion 1231 and a slot 113 that cooperate with each other, wherein the positioning protrusion 1231 is arranged on the second connecting part 123, and the slot 113 is arranged at the connection between the abutting part 112 and the moving part 111.

[0092] Specifically, the positioning protrusion 1231 is arranged on the second connecting part 123, and the slot 113 is arranged at the connection between the abutting part 112 and the moving part 111. Figure 2 and Figure 5The second connecting part 123 has a bottom wall 1232 close to the mounting base 210 and a top wall 1233 away from the mounting base 210. The positioning protrusion 1231 is located on the side of the second connecting part 123 away from the contact part 121, and the positioning protrusion 1231 is offset from the middle of the second connecting part 123 in the height direction. The size of the slot 113 matches the size of the positioning protrusion 1231.

[0093] Specifically, the minimum distance between the positioning protrusion 1231 and the bottom wall 1232 is a first distance, and the minimum distance between the positioning protrusion 1231 and the top wall 1233 is a second distance. The first distance and the second distance are different in size. Because the size of the slot 113 matches the size of the positioning protrusion 1231, the conductive sheet 12 can only be inserted in the correct direction. If the conductive sheet 12 is installed incorrectly, the slot 113 cannot match the conductive sheet 12 with the positioning protrusion 1231, and installation cannot be performed.

[0094] Please refer to Figure 5 , the distance between the positioning protrusion 1231 and the bottom wall 1232 is obviously smaller than the distance between the positioning protrusion 1231 and the top wall 1233. Accordingly, the slot 113 used to match the positioning protrusion 1231 can be a T-shaped structure.

[0095] Specifically, the slot 113 is in communication with the clamping groove 114.

[0096] In addition to the foolproof design achieved by the structural features described above, text or direction prompts can also be marked on the charging sheet to prompt the correct installation position or installation method. For example, left and right can be directly marked on the charging sheet; or different colored markings can also be applied to the charging sheet for prompting.

[0097] The structure of the charging sheet and the mobile support 11 after assembly can be seen in Figure 1 and Figure 4 .

[0098] In order to facilitate power supply to the charging sheet, in some embodiments, the first connecting part 122 can be provided with a power supply member 1221. Please refer to Figure 4 and Figure 5 , at this time the length of the first connecting part 122 is greater than the length of the second connecting part 123, and the power supply member 1221 can be provided on the part of the first connecting part 122 that extends relative to the mobile support 11.

[0099] Specifically, the power supply member 1221 can be a hole structure, and the wire harness with power supply function is provided with a conductive metal bump matched with the power supply member 1221. After the wire harness is inserted into the hole-shaped power supply member 1221, the metal bump can realize fixed connection with the first connecting part 122 and circuit conduction.

[0100] Further, since the length of the first connecting part 122 is greater than the length of the second connecting part 123, an identification for prompting the installation position can be arranged on the outer wall of the first connecting part 122, so that the installation personnel can quickly identify the correct assembly parts and realize corresponding installation.

[0101] In other embodiments, in order to avoid the influence of the first connecting part 122 on the normal movement of the charging device 10 between the first position and the second position, in some embodiments, the first connecting part 122 can be bent after being installed on the moving support 11.

[0102] It can be understood that the charging device 10 provided by the embodiment of the application can effectively improve the flexibility of size and specification adjustment under the premise of meeting the basic charging function, so that the size range is more flexible relative to the existing charging device 10. When the installation space is limited, the charging device 10 can realize the miniaturization improvement of the whole charging device 10 without changing the size of the part used for contacting the cleaning host, reduce the difficulty of miniaturization of the charging device 10, and achieve the effect of reducing the space occupancy ratio of the charging device 10 on the cleaning base station.

[0104] Please refer to Figures 6-8 The embodiment of the application also provides a cleaning base station, which is at least used for charging the cleaning host. The cleaning base station comprises a charging device 10 and a base body 20, the charging device 10 is any of the charging devices 10 described above, and the base body 20 has a mounting seat 210 and a containing cavity 220 for containing the cleaning host.

[0105] In the cleaning base station, the specific structure of the charging device 10 can be the same as that of any of the embodiments of the charging device 10 described above, and will not be repeated here.

[0106] When the cleaning unit enters the receiving cavity 220 and applies a pushing force to the charging device 10, the charging device 10 can move to a second position relative to the receiving cavity 220. When the charging device 10 moves to the second position, the charging device 10 can be electrically connected to the charging component of the cleaning unit to charge the cleaning unit.

[0107] Specifically, the mounting base 210 is provided with a first mounting hole 211 and a second mounting hole 212 arranged at intervals. Please refer to [link / reference]. Figure 6 The second mounting hole 212 is located on the side of the first mounting hole 211 away from the receiving cavity 220.

[0108] The movable shaft 3 is mounted on the mounting base 210 through the first mounting hole 211, and the movable bracket 11 is sleeved on the movable shaft 3; the fixed end 201 of the torsion spring, i.e. the fixed torsion arm 22, is mounted on the mounting base 210 through the second mounting hole 212, and the spring body 21 of the torsion spring is sleeved on the movable shaft 3.

[0109] Please see Figures 7-8 The mounting base 210 is also provided with a limiting wall 230, and a first limiting block 231 protrudes from the limiting wall 230. A second limiting block 13 is provided on the side of the charging component 1 facing the limiting wall 230.

[0110] When charging component 1 is in the first position, please refer to Figure 7 At this time, the aforementioned movable bracket 11 maintains a certain distance from the limiting wall 230; when the charging component 1 moves to the second position, please refer to... Figure 8 The second limiting block 13 moves toward the limiting wall 230 and is attached to the first limiting block 231 provided on the limiting wall 230.

[0111] A portion of the surface of the mounting base 210 protrudes to form a limiting wall 230. The limiting wall 230 protrudes towards the side of the moving path of the charging component 1 to form a first limiting block 231. Depending on the installation position of the charging device 10, the shapes of the limiting walls 230 formed on the left and right sides may be the same or different.

[0112] Please see Figure 2 , Figure 7 and Figure 8 Within this clean base station, the aforementioned charging devices 10 are respectively installed on the left and right sides of the accommodating cavity 220, wherein... Figure 7 and Figure 8 The charging device 10 shown is located on the same side (right side in the figure). Figure 2 The location of the charging device 10 shown is similar to... Figure 7 and Figure 8 The charging device 10 shown is located in different positions. Figure 2 The charging device 10 is located on the left side of the accommodating cavity 220. Correspondingly,Figure 2 The shape of the limiting baffle 230 in the middle is similar to Figure 7 The shape of the limiting baffle 230 in the middle is different.

[0113] Please see Figures 7-8 The receiving cavity 220 is located above the mounting base 210. When the cleaning host leaves the receiving cavity 220, the charging device 10 is in the first position, at which time a large portion of the contact part 112 moves from above the mounting base 210 into the receiving cavity 220; after the cleaning host enters the receiving cavity 220 of the cleaning base station, as the cleaning host moves, the contact part 112 can maintain a close contact with the cleaning host in a straight line as it moves from the first position to the second position under the continuous thrust provided by the cleaning host, until the contact part 112 moves to the second position, at which time only a small portion of the contact part 112 is located in the receiving cavity 220.

[0114] In this embodiment or other similar embodiments, in addition to charging the cleaning host, the cleaning base station can also be used to perform maintenance functions such as dust collection, cleaning, and water replenishment for the cleaning host, which will not be described in detail here.

Therefore, the beneficial effects of the cleaning base station including at least one or more of the above-mentioned charging devices 10 will not be elaborated here. On the other hand, the internal structure of the cleaning base station with the charging device 10 can be improved to a certain extent, becoming more compact and simple. At the same time, the reduced size of the charging device 10 can make more room for other functional modules (such as dust collection modules, cleaning modules, etc.), so as to integrate more and better different functions on the cleaning base station, making the functions of the base station richer and more complete. In addition, the charging device 10 can reduce the difficulty of miniaturizing the base station, reduce the installation space requirements of the cleaning base station, and improve the space utilization rate of the cleaning base station.
