[0046] Figure 1 is a schematic view of the chassis device 1 provided by the embodiment of the present disclosure, Figure 2 is a schematic view of the chassis device 1 cooperating with the cloth assembly 2 provided by the embodiment of the present disclosure, and Figure 3 is an exploded schematic view of the chassis device 1 cooperating with the cloth assembly 2 provided by the embodiment of the present disclosure. Before describing the chassis device 1 provided by the present embodiment, for the convenience of description, the following direction definitions are made: the chassis device 1 can be calibrated by the following three mutually perpendicular axes defined as follows: the lateral axis X, the front-rear axis Y and the vertical axis Z. Among them, the vertical axis Z is the direction of vertically extending upward along the bottom surface of the chassis device 1. As shown in Figure 1, the direction along the vertical axis Z is defined as the first direction.

[0047] The chassis device 1 provided by the present embodiment comprises a chassis assembly 11, a scraping and washing assembly 12, a lifting structure 13 and a limiting structure 14.

[0048] The chassis device 1 is placed in a cleaning base station, which is used in cooperation with a cleaning device (such as a cleaning robot). The cleaning base station is used to accommodate the cleaning device in an idle state, and to provide the cleaning device for charging and cleaning of the cloth. When the cleaning device is accommodated in the cleaning base station, the cleaning device is supported on the chassis device 1.

[0049] Please refer to FIG. 1, the chassis device 1 provided by the embodiment includes a chassis assembly 11 and a scraping assembly 12, the scraping assembly 12 is arranged on the chassis assembly 11, the chassis assembly 11 is used to support the scraping assembly 12, and the scraping assembly 12 is used to clean the cleaning device cloth assembly 2, when the cleaning device is stored in the cleaning base station, the cleaning device cloth assembly 2 is located above the scraping assembly 12.

[0050] Generally, in the related art, the cleaning scheme used by the cleaning base station for cleaning the cloth can only clean the cloth in one direction, specifically: the cleaning device includes a cloth driving assembly 3 connected with the cloth assembly 2, the cloth driving assembly 3 can drive the cloth assembly 2 to rotate when working, when the cleaning device moves into the cleaning base station, the cloth driving assembly 3 is started, the cloth driving assembly 3 can drive the cloth assembly 2 to rotate in a positive direction and move downward, after moving downward for a certain distance, the limit low position is reached, at the limit low position, the cloth driving assembly 3 can only drive the cloth assembly 2 to rotate in the positive direction and no longer drive the cloth assembly 2 to move downward, at this time, the cloth assembly 2 is in contact with the scraping assembly 12, at this time, the cloth driving assembly 3 is continuously driven to drive the cloth assembly 2 to rotate in the positive direction, the cloth assembly 2 rotates relative to the scraping assembly 12, so that the scraping assembly 12 can scrape the cloth assembly 2. When the cloth driving assembly 3 is driven to drive the cloth assembly 2 to rotate in the reverse direction, the cloth assembly 2 will rise, after rising to a certain height, the limit high position is reached, at the limit high position, the cloth driving assembly 3 can only drive the cloth assembly 2 to rotate in the reverse direction and no longer drive the cloth assembly 2 to move upward. Since the cloth assembly 2 rises after rotating in the reverse direction, the cloth assembly 2 is separated from the scraping assembly 12, that is, the cloth assembly 2 cannot be scraped when rotating in the reverse direction. Therefore, the cleaning of the cloth assembly 2 in the cleaning base station can only be cleaned in one direction, which affects the cleaning effect of the cloth. Especially, most of the cloth assemblies 2 are long pile type, and only scraping the cloth in one direction will cause a large amount of dust to be hidden on the back of the cloth, and the cleaning effect of the cloth is poor.

[0051] Based on the above problems, the embodiment adds a lifting structure 13 between the chassis assembly 11 and the scraping assembly 12, the lifting structure 13 is at least used to drive the scraping assembly 12 to lift in a direction away from the chassis assembly 11, so that the cloth assembly 2 can be in contact with the scraping assembly 12 at least during part of the positive rotation and reverse rotation.

[0052] The direction away from the chassis assembly 11 is defined as a first direction, that is, the lifting structure 13 can at least lift the scraping assembly 12 in the first direction, so that the cloth assembly 2 can be in contact with the scraping assembly 12 at least during part of the process of rising to the limit high position when rotating in the reverse direction, which provides a premise for the cloth assembly 2 to still be scraped when rotating in the reverse direction.

[0053] The lifting structure 13 is configured to lift the wiping assembly 12 in the first direction, and the lifting structure 13 is configured to lift the wiping assembly 12 from a first position to a second position in the first direction, the first position being a lowest position of the wiping assembly 12, and the wiping assembly 12 being in contact with the cloth assembly 2 when the cloth assembly 2 is in the extreme low position, and the second position being a highest position of the wiping assembly 12.

[0054] In the embodiment, the lifting structure 13 is configured to lift the wiping assembly 12 at least in the first direction, i.e. in one specific example, the lifting structure 13 is configured to lift the wiping assembly 12 in the first direction only, and the cloth assembly 2 is configured to move the wiping assembly 12 in the first direction downward when the cloth assembly 2 is moving downward in the forward direction, and in another specific example, the lifting structure 13 is configured to lift the wiping assembly 12 in the first direction and to lower the wiping assembly 12 in the first direction.

[0055] The cloth assembly 2 has a moving range in the first direction, i.e. a distance between the extreme low position and the extreme high position described above. In the embodiment, the cloth assembly 2 is configured to be in contact with the wiping assembly 12 at least during part of the reverse rotation, i.e. during the whole process of the cloth assembly 2 moving from the extreme low position to the extreme high position in the reverse direction, the wiping assembly 12 is in contact with the cloth assembly 2 as long as the wiping assembly 12 is lifted upward by the lifting structure 13 during part of the process. For example, the cloth assembly 2 is in contact with the wiping assembly 12 when the cloth assembly 2 is rotated from the extreme low position to a position (the position is lower than the extreme high position) in the reverse direction, and the cloth assembly 2 is not in contact with the wiping assembly 12 when the cloth assembly 2 is rotated to the extreme high position in the reverse direction. Preferably, the lifting structure 13 is configured to lift the wiping assembly 12 upward during the whole process of the cloth assembly 2 moving from the extreme low position to the extreme high position in the reverse direction, so that the lifting structure 13 is in contact with the cloth assembly 2 at all times.

[0056] For lifting the wiping assembly 12 from the first position to the second position, the cloth assembly 2 is configured to move in the first direction, and specifically, when the cloth assembly 2 is moving downward to the extreme low position under the driving of the cloth driving assembly 3, the wiping assembly 12 is in the first position, and the cloth assembly 2 is in contact with the wiping assembly 12. Since the lifting structure 13 is configured to lift the wiping assembly 12, when the cloth assembly 2 is moving upward to the extreme high position in the reverse direction, the lifting structure 13 is configured to lift the wiping assembly 12 upward to the second position, and the wiping assembly 12 is in contact with the cloth assembly 2 during the process of lifting the wiping assembly 12 upward and / or when the wiping assembly 12 is in the second position.

[0057] As the wiping assembly 12 cleans the cloth assembly 2, it is desirable that the cloth driving assembly 3 rotates the cloth assembly 2 while the wiping assembly 12 does not rotate. Therefore, the embodiment provides a limiting structure 14 connected to the wiping assembly 12, which prevents the wiping assembly 12 from rotating relative to the chassis assembly 11, thereby preventing the wiping assembly 12 from rotating with the cloth assembly 2. In an example, the lifting structure 13 can connect the wiping assembly 12 and the chassis assembly 11 to form the limiting structure 14, which prevents the wiping assembly 12 from rotating relative to the chassis assembly 11.

[0058] The chassis device 1 provided by the embodiment can achieve bidirectional cleaning of the cloth assembly 2. The wiping assembly 12 cleans the cloth assembly 2 when the cloth assembly 2 rotates in a forward direction and a reverse direction. The specific description is as follows:

[0059] (I) Cleaning of the cloth assembly 2 by the wiping assembly 12 when the cloth assembly 2 rotates in a forward direction

[0060] When the cleaning device moves into the cleaning base station, the cloth driving assembly 3 is started. The cloth driving assembly 3 can drive the cloth assembly 2 to rotate in a forward direction and move downward. After the cloth assembly 2 moves downward by a certain distance to a limit low position, the wiping assembly 12 is located at a first position. The cloth driving assembly 3 is continuously driven to drive the cloth assembly 2 to rotate in a forward direction. The rotation of the cloth assembly 2 relative to the wiping assembly 12 allows the wiping assembly 12 to clean the cloth assembly 2.

[0061] After the cloth assembly 2 moves downward by a certain distance to a limit low position, the wiping assembly 12 is located at a first position. As described above, there are two cases. One is that the cloth assembly 2 drives the wiping assembly 12 to move downward in a first direction. The other is that the lifting structure 13 drives the wiping assembly 12 to move downward in the first direction.

[0062] For the case that the cloth assembly 2 drives the wiping assembly 12 to move downward in the first direction, the cloth assembly 2 is in contact with the wiping assembly 12 and rotates in a forward direction relative to the wiping assembly 12, thereby allowing the cloth assembly 2 to be cleaned.

[0063] For the case that the lifting structure 13 drives the wiping assembly 12 to move downward in the first direction, when the cloth driving assembly 3 drives the cloth assembly 2 to rotate in a forward direction and move downward, the lifting structure 13 can be controlled to drive the wiping assembly 12 to move downward in the first direction and abut against the cloth assembly 2. Alternatively, the lifting structure 13 can be controlled to quickly drive the wiping assembly 12 to move downward to the first position, so that the cloth assembly 2 abuts against the wiping assembly 12 after moving downward to the limit low position.

[0064] (II) Cleaning of the cloth assembly 2 by the wiping assembly 12 when the cloth assembly 2 rotates in a reverse direction

[0065] For the cleaning of the wiping assembly 2 by the scraping and cleaning assembly 12 when the wiping assembly 2 reversely rotates, based on the height difference between the second position, there are two cases in the cleaning process of the wiping assembly 2 by the wiping assembly 2 reversely rotating:

[0066] Case one: when the scraping and cleaning assembly 12 is in the second position and the wiping assembly 2 is in the limit high position, the wiping assembly 2 is in contact with the scraping and cleaning assembly 12.

[0067] That is, when the wiping assembly 2 is lifted to the limit high position under the driving of the wiping driving assembly 3, the scraping and cleaning assembly 12 is lifted to the second position under the action of the lifting structure 13, and at this time, the wiping assembly 2 is still in contact with the scraping and cleaning assembly 12.

[0068] For this, in the process of the wiping assembly 2 reversely rotating and rising, the scraping and cleaning assembly 12 can always be in abutment with the wiping assembly 2 through the lifting structure 13, so as to realize the scraping and cleaning of the wiping assembly 2 by the scraping and cleaning assembly 12 in the process of the wiping assembly 2 reversely rotating and rising and when the wiping assembly 2 is in the limit high position.

[0069] Of course, in the process of the wiping assembly 2 reversely rotating and rising, the lifting structure 13 can also be controlled so that when the wiping assembly 2 reversely rotates to the limit high position, the lifting structure 13 is controlled again to lift the scraping and cleaning assembly 12 to the second position.

[0070] Case two: when the scraping and cleaning assembly 12 is in the second position and the wiping assembly 2 is in the limit high position, the wiping assembly 2 is not in contact with the scraping and cleaning assembly 12.

[0071] If the limit high position of the wiping assembly 2 and the second position are relatively far apart, the scraping and cleaning assembly 12 is separated from the wiping assembly 2 when the wiping assembly 2 reversely rotates and rises to the limit high position, that is, the wiping assembly 2 cannot be cleaned when it is in the limit high position.

[0072] Since in case two, the wiping assembly 2 can only be cleaned when the scraping and cleaning assembly 12 is in contact with the wiping assembly 2 in the process of the wiping assembly 2 reversely rotating and rising, the wiping assembly 2 cannot be reversely cleaned when it is in the limit high position, in order to avoid the poor cleaning effect of the wiping assembly 2 when it reversely rotates, the wiping driving assembly 3 can be controlled to repeatedly drive the wiping assembly 2 to rise and fall, so as to realize the multiple bidirectional cleaning of the wiping assembly 2.

[0073] The chassis device 1 provided by the embodiment can lift the scraping and washing assembly 12 in the first direction through the lifting structure, and the upward lifting of the scraping and washing assembly 12 can be in contact with the reverse-rotating wiping assembly 2 at least in part of the period, and the rotation of the scraping and washing assembly 12 relative to the chassis assembly 11 is prevented through the limiting structure 14, so that the reverse cleaning of the wiping assembly 2 is realized when the wiping assembly 2 is reversely rotated and lifted, and the wiping assembly 2 also keeps in contact with the scraping and washing assembly 12 at least in part of the period when the wiping assembly 2 is in the forward rotation state, so that the bidirectional cleaning of the wiping assembly 2 can be realized, the cleaning efficiency and cleaning effect of the wiping assembly 2 are improved, so that the influence of the poor cleaning degree of the wiping assembly on the cleaning effect of the cleaning equipment on the surface to be cleaned such as the ground can be effectively avoided, and the user experience is improved; in addition, the bidirectional cleaning of the wiping assembly can be realized only through the active forward and reverse rotation of the wiping assembly 2, and the scraping and washing assembly does not need to rotate, and does not need to be additionally provided with an active motor on the scraping and washing assembly, so that the cost is low.

[0074] In the embodiment, water can be injected to the wiping assembly 2 when the scraping and washing assembly 12 scrapes and washes the rotating wiping assembly 2, so as to facilitate the scraping and washing of the wiping assembly 2. The water can be injected to the wiping assembly 2 in the following two ways: one is that the water is injected to the wiping assembly 2 through the water supply device of the cleaning equipment; and the other is that the water is injected to the wiping assembly 2 through the water spraying assembly on the chassis device 1.

[0075] Referring to FIG. 3, the wiping assembly 2 generally includes a wiping cloth 21 and a wiping cloth support 22, the wiping cloth 21 is fixed on the wiping cloth support 22, and the wiping cloth support 22 is provided with a support hole 221.

[0076] As to the water injection to the wiping assembly 2 through the water supply device of the cleaning equipment, specifically, when the water supply device works, the clean water in the cleaning equipment can flow to the wiping cloth 21 through the support hole 221 to wet the wiping cloth 21. For example, when the wiping assembly 2 is located at the low position and the scraping and washing assembly 12 is located at the first position, the water supply device can be started to wet the wiping cloth 21 to realize the cleaning of the wiping assembly 2 in the forward rotation state; when the wiping assembly 2 is located at the high position and the scraping and washing assembly 12 is located at the second position, the water supply device can be started to wet the wiping cloth 21 to realize the cleaning of the wiping assembly 2 in the reverse rotation state. As to the support hole 221, in the example of FIG. 3, the support hole 221 is multiple and uniformly distributed along the circumferential direction of the wiping cloth support 22.

[0077] As to the water injection to the wiping assembly 2 through the water spraying assembly on the chassis device 1, specifically, the water spraying assembly can be provided on the chassis device 1, the water spraying assembly includes a spray head, when the cleaning equipment is accommodated in the cleaning base station, the spray head is located directly below the wiping assembly 2, when the wiping assembly 2 is located at the low position and the scraping and washing assembly 12 is located at the first position, the water spraying assembly can be started to wet the wiping cloth 21 to realize the cleaning of the wiping assembly 2 in the forward rotation state; when the wiping assembly 2 is located at the high position and the scraping and washing assembly 12 is located at the second position, the water spraying assembly can be started to wet the wiping cloth 21 to realize the cleaning of the wiping assembly 2 in the reverse rotation state.

[0078] The water pump is connected to the water tank of the cleaning base station through a pipeline, and the spray head is connected to the water pump through a pipeline.

[0079] In one specific example, the spray head is fixed on the chassis device 1, i.e., the spray head is fixed on the chassis device 1. In another specific example, the height of the spray head is adjustable. For example, when the mop assembly 2 is reversely rotated to drive the scraping assembly 12 to move upward, the spray head is also raised at this time, so that when the mop assembly 2 is in the high position and the scraping assembly 12 is in the second position, the spray head is still close to the mop assembly 2. For the height-adjustable spray head, the spray head can be connected to a linear driving structure, which can be a pneumatic cylinder or a hydraulic cylinder, to drive the spray head to move in the height direction.

[0080] In one embodiment, the lifting structure 13 is an elastic component, and the direction in which the lifting structure 13 is elastically deformed is consistent with the direction in which the scraping assembly 12 moves. In another embodiment, the lifting structure 13 is a linear driving mechanism.

[0081] As described above, the direction in which the scraping assembly 12 is lifted is defined as the first direction. In the embodiment in which the lifting structure 13 is an elastic component, the scraping assembly 12 can be lifted from the first position to the second position in the first direction under the action of the elastic force. The scraping assembly 12 can be in contact with the scraping assembly 12 under the action of the elastic force of the lifting structure 13.

[0082] In one application, when the cleaning device is not accommodated in the cleaning base station, the scraping assembly 12 is in the second position under the action of the elastic force of the lifting structure 13. When the cleaning device moves into the cleaning base station, the mop assembly 2 is located directly above the scraping assembly 12. The mop driving assembly 3 is started to drive the mop assembly 2 to rotate forward and move downward. The scraping assembly 12 moves downward under the pressure of the mop assembly 2 and compresses the lifting structure 13 until the lifting structure 13 is compressed to the first position, and the mop assembly 2 reaches the extreme low position. When the mop driving assembly 3 reversely rotates the mop assembly 2, for example, when the mop assembly 2 is reversed at the extreme low position, the scraping assembly 12 abuts against the mop assembly 2 under the action of the elastic force of the lifting structure 13 to achieve cleaning.

[0083] It can be understood that the driving assembly 3 can stop the mop assembly 2 at any position between the extreme high position and the extreme low position, or can be forward or reverse rotated at any position, as long as the scraping assembly 12 can abut against the lifting structure 13 when the lifting structure 13 is in the compressed state to achieve cleaning of the mop assembly 2. Of course, in the cleaning base station, a cleaning tray can be provided at the low position, and the cleaning tray contains cleaning liquid. The mop assembly 2 can be in contact with the cleaning liquid when it is at the extreme low position.

[0084] In the embodiment where the lifting structure 13 is a resilient component, the scrubbing assembly 12 is in the second position under the elastic force of the lifting structure 13. The second position can be the two cases as described above. For example, when the scrubbing assembly 12 is in the second position and the wiping assembly 2 is in the extreme high position, the wiping assembly 2 is in contact with the scrubbing assembly 12. At this time, since the wiping assembly 2 is in the extreme high position, the wiping assembly 2 is still in contact with the scrubbing assembly 12, which has certain influence on the cleaning device leaving the cleaning base station. However, the cleaning device can still overcome the resistance between the wiping assembly 2 and the scrubbing assembly 12 under the driving of the driving device to leave the cleaning base station. When the cleaning device returns to the cleaning base station, the scrubbing assembly 12 is in the extreme high position (the second position), which has certain hindering effect on the cleaning device entering the cleaning base station. However, the cleaning device can still overcome the resistance between the wiping assembly 2 and the scrubbing assembly 12 under the driving of the driving device to return to the cleaning base station.

[0085] When the lifting structure 13 is a resilient component, the greater the compression deformation of the lifting structure 13 when the scrubbing assembly 12 is in the first position, and the greater the elastic force of the lifting structure 13 acting on the scrubbing assembly 12 when the wiping assembly 2 is in the extreme low position and in contact with the scrubbing assembly 12. When the scrubbing assembly 12 is in the second position, the compression deformation of the lifting structure 13 decreases. In the embodiment where the lifting structure 13 is a resilient component, a lifting structure 13 with a reasonable elastic coefficient can be selected to minimize the extrusion force of the lifting structure 13 on the wiping assembly 2 when the scrubbing assembly 12 is in the second position and the wiping assembly 2 is in the extreme high position and in contact with the scrubbing assembly 12, so as to reduce the influence of the scrubbing assembly 12 on the cleaning device when the cleaning device leaves or returns to the cleaning base station.

[0086] In the embodiment where the lifting structure 13 is a resilient component, when the scrubbing assembly 12 is in the first position, there are two cases: one is that when the scrubbing assembly 12 is in the first position, the scrubbing assembly 12 can continue to move downward if it is continuously pressed downward; the other is that when the scrubbing assembly 12 is in the first position, the scrubbing assembly 12 cannot continue to move downward if it is continuously pressed downward, for example, when the scrubbing assembly 12 is in the first position, the scrubbing assembly 12 abuts against the chassis assembly 11, so that the scrubbing assembly 12 cannot continue to move downward.

[0087] For example, the resilient component can be a spring, elastic rubber, or an elastic buffer device prepared by using a spring.

[0088] By using a resilient component for the lifting structure 13, the scrubbing assembly 12 can easily abut against the wiping assembly 2 during the lifting and lowering of the wiping assembly 2, and the wiping assembly 2 can be bidirectionally cleaned. The chassis device 1 has a relatively simple structure and low cost.

[0089] In the embodiment where the lifting structure 13 is a linear drive mechanism, the lifting structure 13 actively drives the wiping assembly 12 to move in the first direction. For example, when the cleaning device is not received in the cleaning base station, the lifting structure 13 drives the wiping assembly 12 to move to the first position; when the cleaning device is received in the cleaning base station, the cloth assembly 2 is lowered to the limit low position in the forward rotation, and can be in contact with the wiping assembly 12 to realize cleaning. Of course, the cloth assembly 2 can also be cleaned in the reverse rotation. When the cloth assembly 2 is reversely rotated and raised, the lifting structure 13 can be controlled to be inactivated, and when the cloth assembly 2 reaches the limit high position, the lifting structure 13 is controlled to drive the wiping assembly 12 to rise to the second position, so that the cloth assembly 2 is in contact with the wiping assembly 12 to clean the cloth assembly 2. When the cleaning of the cloth assembly 2 is completed, the lifting structure 13 is controlled to move, so that the lifting structure 13 drives the wiping assembly 12 to move to the first position. Thus, when the cleaning device enters or leaves the cleaning base station, the wiping assembly 12 does not affect the cloth assembly 2.

[0090] For example, the linear drive mechanism can be a linear motor or a hydraulic cylinder.

[0091] Compared with the embodiment where the lifting structure 13 adopts the elastic component, the motion state of the lifting structure 13 is decoupled from the motion state of the cloth assembly 2, so that the cleaning time and position of the wiping assembly 12 on the cloth assembly 2 can be flexibly controlled.

[0092] In one embodiment, referring to FIG. 4, an exploded schematic view of the chassis assembly 11 and the wiping assembly 12 in the chassis device 1 provided by the embodiment of the present disclosure is shown. The wiping assembly 12 includes a wiping column 121, and the chassis assembly 11 includes a base column 113. The wiping column 121 is connected to the base column 113 in a plug-in manner.

[0093] In the embodiment, the wiping assembly 12 is arranged on the chassis assembly 11 by the plug-in connection of the wiping column 121 and the base column 113, so that the structure is simple and the structure of the chassis device 1 is simplified.

[0094] For the plug-in connection of the wiping column 121 and the base column 113, in one example, the wiping column 121 is inserted into the base column 113, and in another example, the base column 113 is inserted into the wiping column 121.

[0095] When the wiping assembly 12 moves to the second position along the first direction, the base column 113 is still inserted with the wiping column 121, that is, the wiping assembly 12 does not disengage from the base column 113. When the lifting structure 13 is an elastic component and when the wiping assembly 12 moves to the extreme high position, the wiping assembly 12 still abuts against the wiping cloth assembly 2, in order to avoid the situation that the wiping column 121 disengages from the base column 113 when the cleaning device enters the cleaning base station, it is necessary that there is a certain amount of insertion between the base column 113 and the wiping column 121 when the wiping assembly 12 is in the second position, that is, one of the two needs to have a certain depth of insertion into the other.

[0096] Regarding the bottom disc assembly 11, in one example, referring to FIG. 5, which is an exploded schematic view of the bottom disc assembly 11 provided by the embodiment of the present disclosure, the bottom disc assembly 11 comprises a bottom disc main body 111 and a cleaning disc 112, the bottom disc main body 111 is provided with the base column 113, the cleaning disc 112 is provided with the avoiding hole 114, the cleaning disc 112 is arranged on the bottom disc main body 111 and the base column 113 passes through the avoiding hole 114, and the lifting structure 13 is arranged between the bottom disc main body 111 and the wiping assembly 12.

[0097] The bottom disc main body 111 is supported on the structure of the cleaning base station except the disc cleaning device 1, and the cleaning disc 112 is supported on the bottom disc main body 111. The cleaning disc 112 is formed with a cleaning groove, which can be used to contain clean water to facilitate the wiping of the wiping assembly 12 to the wiping cloth assembly 2. Of course, the cleaning disc 112 is also provided with a sewage outlet, and the specific shape of the bottom disc main body 111 and the cleaning disc 112 is not limited in the embodiment.

[0098] Regarding the bottom disc assembly 11, in another example, the bottom disc assembly 11 comprises a bottom disc main body 111 and a cleaning disc 112, the cleaning disc 112 is arranged on the bottom disc main body 111, the cleaning disc 112 is provided with the base column 113, and the lifting structure 13 is arranged between the cleaning disc 112 and the wiping assembly 12.

[0099] Regarding the wiping assembly 12, in one example, referring to FIG. 6, which is a schematic view of the wiping assembly 12 provided by the embodiment of the present disclosure, the wiping assembly 12 further comprises a wiping structure 123 and a plurality of supports 122, the plurality of supports 122 are distributed at intervals along the circumferential direction of the wiping column 121 at the end of the wiping column 121 away from the bottom disc assembly 11, and the wiping structure 123 is distributed on the side of each support 122 away from the bottom disc assembly 11.

[0100] In the embodiment, the plurality of supports 122 refers to two or more supports 122, and preferably the scraping and cleaning assembly 12 comprises a plurality of supports 122, but when the number of supports 122 is one, the wiping cloth assembly 2 can also be cleaned, but by arranging a plurality of supports 122, a better cleaning effect of the wiping cloth assembly 2 can be achieved. For example, the scraping and cleaning assembly 12 comprises three or four supports 122, and the supports 122 can be arranged in a strip-shaped structure. Please refer to FIG. 6, which shows that the scraping and cleaning assembly 12 comprises three supports 122, and the three supports 122 are uniformly and spacedly arranged on the scraping column 121.

[0101] For example, the support 122 is integrally formed with the scraping column 121, or the support 122 is detachably fixed to the scraping column 121 by a connecting piece.

[0102] For the scraping structure 123, for example, the scraping structure 123 is a tooth or a protrusion arranged on the support 122, or the scraping structure 123 is a brush hair. When the scraping structure 123 is a tooth or a protrusion arranged on the support 122, the support 122 is preferably integrally formed with the scraping structure 123. Please refer to FIG. 6, which shows that the scraping structure 123 is a protrusion arranged on the support 122.

[0103] The end of the scraping column 121 away from the base plate assembly 11 is an upper end face 124, please refer to FIG. 6, which shows the upper end face 124, and the scraping structure 123 is higher than the upper end face 124 of the scraping column 121. When the scraping and cleaning assembly 12 abuts against the wiping cloth assembly 2, the scraping structure 123 contacts the wiping cloth assembly 2.

[0104] When the wiping cloth assembly 2 rotates relative to the scraping and cleaning assembly 12, the scraping structure 123 can effectively brush off the dirt adhered to the wiping cloth, reduce the adhesion amount of the dirt, and improve the cleaning efficiency of the wiping cloth.

[0105] In one example, two scraping and cleaning assemblies 12 are arranged on the base plate assembly 11, each scraping and cleaning assembly 12 is connected to the limiting structure 14, and the lifting structure 13 is arranged between each scraping and cleaning assembly 12 and the base plate assembly 11. At this time, it is suitable for the case that the cleaning device is provided with two wiping cloth assemblies 2. In one example, one scraping and cleaning assembly 12 is arranged on the base plate assembly 11, and at this time, it is suitable for the case that the cleaning device is provided with one wiping cloth assembly 2. That is, the number of scraping and cleaning assemblies 12 arranged on the base plate assembly 11 can be reasonably arranged according to the actual situation.

[0106] Please refer to FIGS. 7-9, FIG. 7 is a top view of the base plate device 1 in the embodiment; FIG. 8 is a sectional view of A-A in FIG. 7; and FIG. 9 is a partial enlarged view of A in FIG. 8.

[0107] Regarding the limiting structure 14, in one embodiment, please refer to FIG. 8 and FIG. 9, the limiting structure 14 is formed between the scrubbing column 121 and the base column 113, and is used to guide the movement of the scrubbing assembly 12 relative to the base plate assembly 11, that is, when the scrubbing assembly 12 is lifted in a direction away from the base plate assembly 11, the limiting structure 14 can guide the movement of the base plate assembly 11, and similarly, when the scrubbing assembly 12 is close to the base plate assembly 11, the limiting structure 14 can guide the movement of the base plate assembly 11.

[0108] Since the limiting structure 14 is used to guide the movement of the scrubbing assembly 12 relative to the base plate assembly 11, it can prevent the scrubbing assembly 12 from rotating or tilting relative to the base plate assembly 11, and guide the lifting of the scrubbing assembly 12 by the lifting structure 13 in the first direction.

[0109] In this embodiment, the scrubbing assembly 12 is arranged on the base plate assembly 11 by the plug-in connection of the scrubbing column 121 and the base column 113, and the limiting structure 14 is formed between the scrubbing column 121 and the base column 113, rather than adding a limiting structure 14 between the scrubbing assembly 12 and the base plate assembly 11 outside the scrubbing column 121 and the base column 113, which can simplify the structure of the base plate device 1.

[0110] In this embodiment, by forming the limiting structure 14 between the scrubbing column 121 and the base column 113, when the lifting structure 13 is an elastic device, the fixed connection between the lifting structure 13 and the scrubbing assembly 12 can be cancelled, which prevents the force applied to the scrubbing assembly 12 when the cloth assembly 2 rotates from indirectly acting on the lifting structure 13, and is beneficial to protecting the lifting structure 13 and improving the service life of the lifting structure 13.

[0111] Please refer to FIG. 9, in the example in FIG. 9, a step is formed on the circumferential inner side of the scrubbing column 121, which can be referred to as a scrubbing step 1213; a step is formed on the circumferential outer side of the base column 113, which can be referred to as a base step 1133. When the scrubbing column 121 is in the first position, the scrubbing step 1213 on the circumferential inner side of the scrubbing column 121 is in contact with the base step 1133 on the circumferential outer side of the base column 113; or, the scrubbing step 1213 on the circumferential inner side of the scrubbing column 121 is not in contact with the base step 1133 on the circumferential outer side of the base column 113.

[0112] Based on the example that the scrubbing assembly 12 includes the scrubbing column 121 and the base plate assembly 11 includes the base column 113, regarding the position of the lifting structure 13, in one embodiment, please refer to FIG. 9, the lifting structure 13 is located in the scrubbing column 121 and the base column 113.

[0113] By locating the lifting structure 13 inside the scrubbing column 121 and the base column 113, the lifting structure 13 can be protected, and the service life of the lifting structure 13 can be improved.

[0114] Please refer to FIG. 9 and FIG. 10, FIG. 9 shows a schematic diagram of the scrubbing column 121 located at a first position, and FIG. 10 shows a schematic diagram of the scrubbing column 121 located at a second position.

[0115] In comparison with locating the lifting structure 13 inside the scrubbing column 121 and the base column 113, in an example, the lifting structure 13 is located outside the scrubbing column 121 and the base column 113. For example, when the lifting structure 13 is an elastic component, the elastic component is arranged between the support 122 of the scrubbing assembly 12 and the chassis assembly 11.

[0116] In the example of locating the lifting structure 13 inside the scrubbing column 121 and the base column 113, if the lifting structure 13 is an elastic component, the specific location of the lifting structure 13 inside the scrubbing column 121 and the base column 113 is as follows:

[0117] In an embodiment, the top surface of the base column 113 is provided with a hole, the scrubbing column 121 is inserted into the hole on the base column 113, the lifting structure 13 is located below the scrubbing column 121 and between the inner bottom surface of the base column 113, and the number of the lifting structure 13 is one or more.

[0118] In another embodiment, the bottom surface of the scrubbing column 121 is provided with an opening, the base column 113 is inserted into the opening on the scrubbing column 121, the lifting structure 13 is located above the base column 113 and between the inner bottom surface of the scrubbing column 121, and the number of the lifting structure 13 is one or more.

[0119] In another embodiment, as shown in FIG. 9, the base column 113 is provided with a base hole 1131, the base hole 1131 is provided with a guide column 1132, and there is a gap between the guide column 1132 and the hole wall of the base hole 1131. The scraping column 121 is provided with a scraping hole 1211, the scraping hole 1211 is provided with a positioning column 1212, and there is a gap between the positioning column 1212 and the hole wall of the scraping hole 1211. The guide column 1132 and the positioning column 1212 are inserted. The lifting structure 13 is preferably a spring member. The lifting structure 13 is sleeved outside the guide column 1132 and the positioning column 1212. The position of the lifting structure 13 is positioned by sleeving the lifting structure 13 on the guide column 1132 and the positioning column 1212. In this embodiment, the base hole 1131 on the base column 113 can be a through hole. At this time, the guide column 1132 in the base hole 1131 is connected to the bottom disc main body 111 or the cleaning disc 112. As shown in FIG. 9, the guide column 1132 is connected to the bottom disc main body 111. Regarding the base hole 1131 on the base column 113, in another embodiment, the base hole 1131 is a blind hole. The base column 113 includes a cylinder with a bottom and a guide column 1132 extending upward from the bottom of the cylinder.

[0120] In another embodiment, the difference from the structure shown in FIG. 9 is that the positioning column 1212 is not arranged in the scraping hole 1211. Only the guide column 1132 is arranged in the base hole 1131 of the base column 113. The lifting structure 13 is sleeved on the guide column 1132. The position of the lifting structure 13 is positioned by sleeving the lifting structure 13 on the guide column 1132.

[0121] In another embodiment, the difference from the structure shown in FIG. 9 is that the guide column 1132 is not arranged in the base hole 1131. Only the positioning column 1212 is arranged in the scraping hole 1211 of the scraping column 121. The lifting structure 13 is sleeved on the positioning column 1212. The position of the lifting structure 13 is positioned by sleeving the lifting structure 13 on the positioning column 1212.

[0122] In the example that the lifting structure 13 is a spring member, in one embodiment, the two ends of the lifting structure 13 are respectively connected to the base column 113 and the scraping column 121. Alternatively, in another embodiment, neither end of the lifting structure 13 is connected to the base column 113 and the scraping column 121. Alternatively, in another embodiment, one end of the lifting structure 13 is connected to the base column 113 or the scraping column 121.

[0123] Regarding the insertion of the guide column 1132 and the positioning column 1212, in one example, the guide column 1132 is inserted into the positioning column 1212. In another example, the positioning column 1212 is inserted into the guide column 1132. As shown in FIG. 9, the guide column 1132 is introduced into the positioning column 1212.

[0124] As mentioned above, the limiting structure 14 is formed between the scraping column 121 and the base column 113. In one embodiment, the limiting structure 14 is formed between the outer circumferential sidewall of the base column 113 and the inner sidewall of the scraping column 121; in another embodiment, the limiting structure 14 is formed between the outer circumferential sidewall of the scraping column 121 and the inner sidewall of the base column 113. Please refer to FIG. 9, which shows that the base column 113 is inserted into the scraping column 121, i.e. the limiting structure 14 is formed between the outer circumferential sidewall of the base column 113 and the inner sidewall of the scraping column 121.

[0125] In the following scenario, i.e. when the scraping assembly 12 is in the first position, the scraping assembly 12 cannot continue to move downward, in combination with FIG. 9, it can be configured that when the scraping assembly 12 is in the first position, the lower end of the scraping column 121 is in contact with the base disc assembly 11 to limit the scraping assembly 12 from continuing to move downward; or, it can be configured that when the scraping assembly 12 is in the first position, the guide column 1132 is in abutment with the scraping column 121 to limit the scraping assembly 12 from continuing to move downward; or, please refer to FIG. 9, it can be configured that when the scraping assembly 12 is in the first position, the scraping step 1213 on the circumferential inner side of the scraping column 121 is in contact with the base step 1133 on the circumferential outer side of the base column 113 to limit the scraping assembly 12 from continuing to move downward.

[0126] Based on the embodiment in which the guide column 1132 is arranged in the base column 113 and the positioning column 1212 is arranged in the scraping hole 1211, in one embodiment, the limiting structure 14 is formed between the guide column 1132 and the positioning column 1212. When the limiting structure 14 is arranged between the guide column 1132 and the positioning column 1212, the limiting structure 14 can not be arranged between the outer circumferential sidewall of the base column 113 and the inner sidewall of the scraping column 121 or between the outer circumferential sidewall of the scraping column 121 and the inner sidewall of the base column 113.

[0127] FIG. 11 is a schematic view of the base disc main body 111 according to an embodiment of the present disclosure; FIG. 12 is an enlarged view of part B in FIG. 11; and FIG. 13 is a schematic view of the scraping assembly according to an embodiment of the present disclosure.

[0128] Regarding the limiting structure 14, in one embodiment, please refer to FIG. 12 and FIG. 13, the limiting structure 14 includes a guide groove 141 and a limiting rib 142, the limiting rib 142 is located in the guide groove 141, and the length extension direction of the guide groove 141 is along the first direction.

[0129] The limiting structure 14 adopts the cooperation structure of the guide groove 141 and the limiting rib 142, which can realize the guidance of the scraping assembly 12 moving along the first direction, and the structure of the limiting structure 14 is simple and convenient for processing.

[0130] In a specific example, referring to FIG. 12, a limiting rib 142 is arranged on the outer circumferential side of the base cylinder 113, and referring to FIG. 13, a guide groove 141 is arranged on the inner side of the scraping cylinder 121 to guide the scraping cylinder 121 to move in the first direction. In a specific example, a guide groove 141 can be arranged on the outer circumferential side of the base cylinder 113, and a limiting rib 142 is arranged on the inner side of the scraping cylinder 121 to guide the scraping cylinder 121 to move in the first direction.

[0131] Regarding the number of limiting ribs 142, in a specific example, the number of limiting ribs 142 is one; referring to FIG. 12, in another specific example, the number of limiting ribs 142 is multiple, and the multiple limiting ribs 142 are distributed along the circumferential direction of the base cylinder 113, and referring to FIG. 13, multiple guide grooves 141 are arranged on the inner side of the scraping cylinder 121, the number of guide grooves 141 is consistent with the number of limiting ribs 142, and the guide grooves 141 correspond to the limiting ribs 142 one by one. By setting the number of limiting ribs 142 to be multiple, the limiting structure 14 can stably guide the scraping assembly 12 to move in the first direction. Preferably, the multiple limiting ribs 142 are uniformly distributed along the circumferential direction of the base cylinder 113.

[0132] In the example of arranging a guide column 1132 in the base cylinder 113 and arranging a positioning column 1212 in the scraping hole 1211, a guide groove 141 and a limiting rib 142 cooperation structure can also be arranged between the guide column 1132 and the positioning column 1212.

[0133] Referring to FIG. 12, in a specific example, the two ends of the limiting rib 142 extend to the two ends of the base cylinder 113 in the first direction (the first direction is parallel to the axial direction of the base cylinder 113).

[0134] Regarding the limiting structure 14, in another embodiment, the guiding in the first direction is achieved by limiting shape. Specifically, for example, the cross-sectional shape of the base cylinder 113 is a regular polygon, the base cylinder 113 is inserted into the scraping cylinder 121, the inner side of the scraping cylinder 121 cooperates with the shape of the outer circumferential side of the base cylinder 113, and the cross-sectional shape of the inner side of the scraping cylinder 121 is also a regular polygon to guide the scraping cylinder 121 to move in the first direction. Of course, in the example of arranging a guide column 1132 in the base cylinder 113 and arranging a positioning column 1212 in the scraping hole 1211, the guide column 1132 and the positioning column 1212 can also be limited by shape to form the limiting structure 14.

[0135] The present embodiment provides a cleaning base station, which comprises the base disc device 1 provided in any of the above embodiments.

[0136] The cleaning base is used in cooperation with a cleaning device (such as a cleaning robot), and is used to accommodate the cleaning device in an idle state, and to charge the cleaning device and to clean the mop of the cleaning device through the chassis device 1.

[0137] The cleaning system provided in the embodiment comprises a cleaning device and the cleaning base provided in the above embodiment; the cleaning device comprises a mop assembly 2 and a mop driving assembly 3 connected with the mop assembly 2, and the mop driving assembly 3 is used to drive the mop assembly 2 to move in the first direction.

[0138] The cleaning device can be a scrubber, a sweeping robot, a sweeping and mopping robot, etc., and the embodiment of the present disclosure is not limited thereto.

[0139] When the mop driving assembly 3 is in action, it can drive the mop assembly 2 to move in the first direction. When the cleaning device is used to clean the ground, the mop driving assembly 3 drives the mop assembly 2 to rotate forward and drives the mop assembly 2 to descend. When the mop assembly 2 descends to a certain distance to the limit low position, the mop assembly 2 does not descend but only rotates forward. At this time, the mop assembly 2 is in contact with the ground. When the cleaning device moves, the ground can be cleaned through the mop assembly 2. When cleaning is not needed, the mop driving assembly 3 drives the mop assembly 2 to rotate reversely, and at the same time, the mop assembly 2 ascends. When the mop assembly 2 ascends to a certain distance to the limit high position, even if the mop assembly 2 rotates reversely, it will not continue to ascend, so as to realize that the mop assembly 2 is lifted off the ground.

[0140] When the cleaning device moves to the cleaning base and the mop assembly 2 needs to be cleaned, the mop driving assembly 3 is started. The mop driving assembly 3 can drive the mop assembly 2 to rotate forward and drive the mop assembly 2 to move downward. When the mop assembly 2 descends to the limit low position, the scraping and washing assembly 12 is also in the first position at this time. The mop driving assembly 3 continues to drive the mop assembly 2 to rotate forward. Since the scraping and washing assembly 12 does not rotate under the limitation of the limiting structure 14, the forward rotation of the mop assembly 2 relative to the scraping and washing assembly 12 enables the scraping and washing assembly 12 to scrape and wash the mop assembly 2. When the mop driving assembly 3 drives the mop assembly 2 to rotate reversely and ascend, since the lifting structure 13 of the cleaning base can drive the scraping and washing assembly 12 to ascend in the first direction, the mop assembly 2 maintains contact with the scraping and washing assembly 12 at least during part of the reverse rotation period, so as to realize that the scraping and washing assembly 12 washes the mop assembly 2 when the mop assembly 2 rotates reversely.
