Embodiments of the present application

[0052] In order to better understand the above technical solutions, the technical solutions of the embodiments of the present application will be described in detail below through the drawings and specific embodiments. It should be understood that the specific features in the embodiments of the present application and the specific embodiments are detailed descriptions of the technical solutions of the embodiments of the present application, and are not limitations of the technical solutions of the present application. In the case of no conflict, the technical features in the embodiments of the present application and the specific embodiments can be combined with each other.

[0053] As shown in FIGS. 1-5, according to a first aspect of the embodiments of the present application, a mop plate structure 100 is provided, comprising: a housing 110; a mop plate body 120, having a working side, the working side being used for cleaning an object to be cleaned; a moving assembly 130, disposed in the housing 110, the moving assembly 130 being used for connecting with the mop plate body 120; a limiting piece 140, disposed at one end of the housing 110 towards the mop plate body 120. In some embodiments, a direction from the mop plate body 120 towards the housing 110 is a first direction, in a case that the moving assembly 130 is in a first stroke, the moving assembly 130 drives the mop plate body 120 to move in the first direction until the mop plate body 120 abuts against the limiting piece 140. In a case that the moving assembly 130 is in a second stroke, the moving assembly 130 continues to move in the first direction, the limiting piece 140 continuously presses the mop plate body 120 until the mop plate body 120 and the moving assembly 130 are separated.

[0054] It can be understood that, compared with the prior art, the present application at least includes the following beneficial effects: The mop plate structure 100 provided by the embodiments of the present application is provided with a shell 110, a mop plate body 120, a moving assembly 130 and a limiting piece 140. In some embodiments, the shell 110 can be arranged in the cleaning robot, and the moving assembly 130 is arranged in the shell 110, thereby protecting the moving assembly 130 through the shell 110, improving the reliability of the moving assembly 130 and prolonging the service life of the moving assembly 130. The limiting piece 140 can be arranged at one end of the shell 110 facing the mop plate body 120, and the movement of the mop plate body 120 towards the shell 110 can be limited through the limiting piece 140. The mop plate body 120 has a working side, and in the case that the cleaning robot performs cleaning work, the mop plate body 120 can be connected to the moving assembly 130, and the working side can be used to wash and clean the object to be cleaned. In the case that the cleaning robot returns to the cleaning base station and needs to disassemble the mop plate body 120, the moving assembly 130 can exert a pulling force on the mop plate body 120 to drive the mop plate body 120 to move, thereby cooperating with the limiting piece 140 to disassemble the mop plate body 120 from the moving assembly 130. In some embodiments, the direction of the mop plate body towards the shell 110 is set as a first direction, and the moving assembly 130 can drive the mop plate body 120 to move in the first direction until the mop plate body 120 abuts against the limiting piece 140. At this time, the moving assembly 130 continues to move in the first direction, while the mop plate body 120 is blocked by the limiting piece 140, and the limiting piece 140 continuously presses the mop plate body 120 to limit the movement of the mop plate body 120 in the first direction, so that the distance between the moving assembly 130 and the mop plate body 120 gradually increases until the pressing force exerted by the limiting piece 140 is greater than the pulling force of the moving assembly 130 on the mop plate body 120, and the mop plate body 120 and the moving assembly 130 are separated. In this way, the automation of separating the mop plate body 120 from the cleaning robot can be realized, manual intervention can be reduced, and user experience can be improved.

[0055] It should be noted that a moving space can be formed inside the shell 110, and an opening 111 can be formed at the bottom of the shell in the vertical direction, the opening 111 being communicated with the moving space. The moving assembly 130 can be arranged in the moving space of the shell and can move in the vertical direction towards the opening 111. The limiting piece 140 can be arranged at the opening 111 of the shell 110 and protrude from the opening 111 of the shell 110. In this way, when the moving assembly 130 drives the mop plate body 120 to move towards the opening 111 of the shell 110, the mop plate body 120 will first be blocked by the limiting piece 140 and cannot continue to move towards the opening 111 of the shell 110, so that the mop plate body 120 and the moving assembly 130 are separated, and the displacement of the mop plate body 120 can be reduced, the space design is more reasonable, the falling distance of the mop plate body 120 after separation is reduced, the protection of the mop plate body 120 is improved, and the service life is prolonged. Exemplarily, the limiting piece 140 can be an integrated structure with the shell 110.

[0056] In some examples, as shown in FIGS. 1-5, the moving assembly 130 includes a first connecting piece 132, and the mop plate body 120 is connected to the first connecting piece 132. A first moving piece 131 is arranged in the shell 110, and the mop plate body 120 is connected to the first moving piece 131 through the first connecting piece 132. The first moving piece 131 is used to drive the mop plate body 120 to move towards or away from the shell 110.

[0057] It can be understood that the moving assembly 130 can be provided with the first moving piece 131 and the first connecting piece 132. In some embodiments, the mop plate body 120 can be connected to the first moving piece 131 through the first connecting piece 132. The first moving piece 131 can be mounted inside the shell 110 from the opening 111 of the shell 110, and the first moving piece 131 can drive the mop plate body 120 to move towards or away from the shell 110 through the first connecting piece 132. In this way, the first moving piece 131 can drive the mop plate body 120 to move in the first direction through the first connecting piece 132, until the mop plate body 120 abuts against the limiting piece 140. Subsequently, when the first moving piece 131 continues to move in the first direction, the mop plate body 120 cannot continue to move in the first direction due to the pressing force applied by the limiting piece 140, and as the moving assembly 130 continues to move in the first direction, the pressing force applied by the limiting piece 140 to the mop plate body 120 will exceed the pulling force applied by the first connecting piece 132 to the mop plate body 120, so that the mop plate body 120 and the first connecting piece 132 are separated, thereby separating the mop plate body 120 and the moving assembly 130.

[0058] Exemplarily, the first connecting member 132 can be provided as a clamping member, and the drag plate body 120 can be connected to the moving assembly 130 in a clamping manner. For example, the clamping member is provided with a clamping plate and a clamping position. In some embodiments, the clamping plate is arranged on the drag plate body 120, and the clamping position is arranged on the moving assembly 130. The clamping plate can be clamped on the clamping position. After the drag plate body 120 is blocked by the limiting member 140, the limiting member 140 exerts a top pressure on the drag plate body 120 to limit the movement of the drag plate body 120 in the first direction. As the moving assembly 130 continues to move in the first direction, the top pressure exerted by the limiting member 140 on the drag plate body 120 continues to increase until the top pressure exceeds the connecting tension of the clamping member, so that the clamping plate and the clamping position are separated, and the drag plate and the moving assembly 130 are separated.

[0059] In some examples, as shown in FIGS. 1-5, the first moving member 131 includes a first sleeve 1311 rotatably arranged in the housing 110, a first internal thread being formed on the first sleeve 1311 in an axial direction, a connecting rod 1312, one end of the connecting rod 1312 being provided with a first external thread, the first external thread being engaged with the first internal thread, or one end of the connecting rod 1312 being provided with the first internal thread, the first sleeve 1311 being provided with the first external thread in the axial direction, a second sleeve 1313 connected to the other end of the connecting rod 1312, the first connecting member 132 being arranged in the second sleeve 1313, and the drag plate body 120 being connectable to the second sleeve 1313.

[0060] It can be understood that the first moving member 131 can be provided with a first sleeve 1311, a connecting rod 1312 and a second sleeve 1313. In some embodiments, the first sleeve 1311 can be axially fixedly arranged in the housing 110, and the first sleeve 1311 can rotate relative to the housing 110. The first sleeve 1311 can be connected to a driving member, and the driving member drives the first sleeve 1311 to rotate. And a first internal thread can be formed in the axial direction of the first sleeve 1311. The end of the connecting rod 1312 close to the first sleeve 1311 can be provided with a first external thread, and the first external thread can be screwed into the first internal thread. In other embodiments, a first external thread can be formed on the first sleeve 1311 in the axial direction, and the end of the connecting rod 1312 close to the first sleeve 1311 can be provided with a first internal thread. In this way, the rotation of the thread can be converted into the linear motion of the connecting rod 1312, so that the distance of the linear motion is more accurate. And by controlling the rotation direction and the number of rotations of the first sleeve 1311, the linear motion direction and the motion distance of the connecting rod 1312 can be controlled. The end of the second sleeve 1313 close to the first sleeve 1311 can be provided with a slot, and the other end of the connecting rod 1312 can be inserted into the slot. Thus, the second sleeve 1313 can move linearly synchronously with the connecting rod 1312. The first connecting member 132 can be arranged in the second sleeve 1313, the squeegee body 120 can be inserted into the second sleeve 1313, and the first connecting member 132 is connected to the squeegee body 120, so that the second sleeve 1313 can drive the squeegee body 120 to move linearly.

[0061] It can be understood that in the case of separating the squeegee body 120 and the moving assembly 130, the first sleeve 1311 rotates in the third direction, and through the engagement of the first external thread and the first internal thread, the connecting rod 1312 moves linearly in the first direction, and the connecting rod 1312 drives the second sleeve 1313 and the squeegee body 120 to move linearly in the first direction. Until the squeegee body 120 abuts against the limiting member 140. Then the first sleeve 1311 continues to rotate in the third direction, and the connecting rod 1312 drives the second sleeve 1313 to move linearly in the first direction. The squeegee body 120 cannot move in the first direction due to the pressing force of the limiting member 140, and as the distance between the squeegee body 120 and the first connecting member 132 increases, the pressing force of the limiting member 140 on the squeegee body 120 will be greater than the pulling force of the first connecting member 132 on the squeegee body 120, so that the part of the squeegee body 120 inserted into the second sleeve 1313 is extracted from the second sleeve 1313.

[0062] Exemplarily, the first sleeve 1311 can be provided with an annular protrusion away from the opening 111 of the shell 110, and the shell 110 can be provided with an annular groove at a corresponding position, the annular protrusion can be inserted into the annular groove, thereby limiting the freedom of the first sleeve 1311 in the axial direction, and the annular protrusion can rotate in the annular groove without affecting the rotational freedom of the first sleeve 1311.

[0063] In some examples, as shown in FIGS. 1-5, the above-mentioned drag plate body 120 includes: a plate body 121; a third sleeve 122 provided on one end of the plate body 121 towards the shell 110 in the height direction of the plate body 121; and a connecting handle 123, one end of the connecting handle 123 is provided on the third sleeve 122, and the other end is used to be connected to the second sleeve 1313 through the first connecting piece 132.

[0064] It can be understood that the drag plate body 120 is provided with the plate body 121, the third sleeve 122 and the connecting handle 123. In some embodiments, one end of the plate body 121 away from the moving assembly 130 can be provided with a cleaning piece to clean the ground through the cleaning piece. One end of the plate body 121 towards the shell 110 can abut against the limiting piece 140. The third sleeve 122 can be provided on one end of the plate body 121 towards the shell 110, the opening of the third sleeve 122 is towards the opening 111 of the shell 110, one end of the connecting handle 123 can be inserted into the third sleeve 122, and the other end of the connecting handle 123 can be inserted into the second sleeve 1313 through the first connecting piece 132.

[0065] It can be understood that the third sleeve 122 can be arranged at the middle of one end of the plate body 121 towards the shell 110. So that the sizes of the plate body 121 on both sides of the third sleeve 122 are equal, to ensure that the pressing force of the limiting piece 140 on the plate body 121 on both sides of the third sleeve 122 is balanced, to ensure balanced force and prevent tilting.

[0066] In some examples, as shown in FIGS. 1-5, the above-mentioned first connecting piece 132 includes: a first magnetic piece 1321 and a first metal piece 1322. In some embodiments, the first magnetic piece 1321 is arranged on the inner wall of the second sleeve 1313, and the first metal piece 1322 is arranged on one end of the connecting handle 123 towards the second sleeve 1313. Or the first magnetic piece 1321 is arranged on one end of the connecting handle 123 towards the second sleeve 1313, and the first metal piece 1322 is arranged on the inner wall of the second sleeve 1313. Or the first magnetic piece 1321 is arranged on one end of the connecting handle 123 towards the second sleeve 1313, and the first metal piece 1322 is arranged on the inner wall of the second sleeve 1313.

[0067] It can be understood that the first connecting member 132 can be provided with a first magnetic member 1321 and a first metal member 1322. The connecting handle 123 can be connected to the second sleeve 1313 by the magnetic force of the first magnetic member 1321. In some embodiments, the first magnetic member 1321 can be arranged at the inner wall of the end of the second sleeve 1313 facing the connecting handle 123, and the first metal member 1322 can be arranged at the end of the connecting handle 123 facing the second sleeve 1313. The first metal member 1322 is adsorbed to the first magnetic member 1321 by the magnetic force, so as to connect the connecting handle 123 to the second sleeve 1313. Alternatively, the first metal member 1322 can be arranged at the inner wall of the end of the second sleeve 1313 facing the connecting handle 123, and the first magnetic member 1321 can be arranged at the end of the connecting handle 123 facing the second sleeve 1313. The first metal member 1322 is adsorbed to the first magnetic member 1321 by the magnetic force, so as to connect the connecting handle 123 to the second sleeve 1313. Alternatively, two first magnetic members 1321 can be arranged. One of the first magnetic members 1321 is arranged at the end of the connecting handle 123 facing the second sleeve 1313, and the other first magnetic member 1321 is arranged at the inner wall of the end of the second sleeve 1313 facing the connecting handle 123. The connecting handle 123 is connected to the second sleeve 1313 by the adsorption force of the two first magnetic members 1321. In this way, the connection is simple and fast, and the first connecting member 132 will not be worn, aged and deformed due to frequent use. The connection stability is ensured, and the service life is prolonged.

[0068] It should be noted that in the case of separating the drag plate body 120 and the moving assembly 130, the second sleeve 1313 can exert a pulling force on the connecting handle 123 by the adsorption force of the first magnetic member 1321, so that the first moving member 131 can drive the drag plate body 120 to move in the first direction until the drag plate body 120 abuts against the limiting member 140. Subsequently, when the first moving member 131 continues to move in the first direction, the drag plate body 120 cannot continue to move in the first direction due to the pressing force exerted by the limiting member 140, and as the moving assembly 130 continues to move in the first direction, the second sleeve 1313 and the connecting handle 123 gradually separate, and as the distance between the first magnetic member 1321 and the drag plate body 120 becomes farther, the adsorption force becomes smaller, so that the pressing force exerted by the limiting member 140 on the drag plate body 120 can exceed the adsorption force of the first magnetic member 1321, to ensure that the drag plate body 120 can smoothly and stably separate from the moving assembly 130.

[0069] In some examples, as shown in FIGS. 1-5, the above-mentioned drag plate structure 100 further comprises an elastic member 150 connected between the above-mentioned third sleeve 122 and the above-mentioned connecting handle 123.

[0070] It can be understood that the squeegee structure 100 is also provided with an elastic member 150. In some embodiments, the elastic member 150 can be arranged in the third sleeve 122 along the axial direction of the third sleeve 122, and the connecting handle 123 can be connected to the elastic member 150. The connecting handle 123 can move along the axial direction of the third sleeve 122. In this way, when the squeegee body 120 and the moving assembly 130 are connected, the connecting handle 123 can be extended from the third sleeve 122 under the action of the magnetic force, and the extended part is connected to the inner bottom wall of the second sleeve 1313. At this time, the elastic member 150 is elongated under the action of the tensile force. When the squeegee body 120 and the moving assembly 130 are separated, the elastic member 150 will rebound to exert a pulling force on the connecting handle 123 away from the second sleeve 1313, which, in combination with the pressing force exerted by the limiting member 140 on the squeegee body 120, can quickly separate the connecting handle 123 from the second sleeve 1313, and the elastic member 150 drives the connecting handle 123 to move towards the third sleeve 122, thereby improving the disassembly speed and stability. Moreover, due to the improved separation speed, the stroke of the second sleeve 1313 is reduced, thereby more reasonably utilizing the space in the housing 110, shortening the overall height of the housing 110, facilitating the overall space layout of the cleaning robot, and improving the space utilization rate.

[0071] In some examples, the stroke of the above-mentioned first moving member 131 driving the above-mentioned squeegee body 120 to move is greater than the sum of the sizes of the above-mentioned third sleeve 122 and the above-mentioned connecting handle 123 located in the above-mentioned second sleeve 1313. In some embodiments, when the above-mentioned limiting member 140 presses the above-mentioned squeegee body 120, the above-mentioned first moving member 131 continues to move in the above-mentioned first direction until the other end of the above-mentioned connecting handle 123 is separated from the above-mentioned second sleeve 1313.

[0072] It can be understood that when the first sleeve 1311 rotates, the threaded connection between the connecting rod 1312 and the first sleeve 1311 will convert the rotation into a linear motion of the connecting rod 1312, thereby moving the tray body 120 towards or away from the opening 111 of the shell 110 through the first connecting piece 132. The stroke of the first moving piece 131 moving the tray body 120 is greater than the sum of the dimensions of the third sleeve 122 and the connecting handle 123 in the second sleeve 1313. In this way, the first sleeve 1311 is rotated in one direction, so that the connecting rod 1312 moves vertically upwards, and the tray body 120 is moved towards the opening 111 of the shell 110 through the first connecting piece 132. During the movement, the tray body 120 will be blocked by the limiting piece 140 and cannot continue to move towards the opening 111 of the shell 110. The first sleeve 1311 continues to rotate, so that the connecting rod 1312 exerts an upward pulling force on the tray body 120 through the first connecting piece 132. When the pulling force is greater than the connecting force of the first connecting piece 132 on the connecting handle 123 of the tray body 120, the connecting handle 123 and the connecting rod 1312 are separated, thereby separating the tray body 120 and the moving assembly 130.

[0073] In some examples, as shown in FIGS. 1-5, the above-mentioned limiting piece 140 includes a second moving piece arranged on the outer side wall of the shell 110, and the second moving piece is movable along the outer side wall of the shell 110; and a second connecting piece 142 for connecting the tray body 120 to the second moving piece. In some embodiments, when the limiting piece 140 presses the tray body 120, the moving assembly 130 continues to move in the first direction, the second moving piece presses the tray body 120 and moves in the second direction until the tray body 120 and the moving assembly 130 are separated, and the first direction and the second direction are opposite.

[0074] It can be understood that the limiting piece 140 can be provided with a second moving piece and a second connecting piece 142. In some embodiments, the second moving piece can be arranged on the outer side wall of the shell 110 close to the opening 111, and the second moving piece can move along the outer side wall of the shell 110 towards or away from the opening 111 of the shell 110. And the second moving piece can be connected to the mop body 120 through the second connecting piece 142. In this way, during the separation of the mop body 120 and the moving assembly 130, the moving assembly 130 drives the mop body 120 to move in the first direction, so that the mop body 120 abuts against the limiting piece 140, and the second connecting piece 142 is connected to the mop body 120. When the moving assembly 130 continues to move in the first direction, the second moving piece can press the mop body 120, and the second moving piece can move together with the mop body 120 in the second direction until the mop body 120 and the moving assembly 130 are separated. By arranging the second moving piece and arranging the movement directions of the second moving piece and the first moving piece 131 opposite to each other, the separation stroke of the mop body 120 is increased, the separation speed of the mop body 120 is improved, and the separation stroke of the mop body 120 is reduced without changing the height dimensions of each component, so as to more reasonably use the space in the shell 110, shorten the overall height of the shell 110, facilitate the space layout of the overall cleaning robot, and improve the space utilization rate.

[0075] In some examples, as shown in FIGS. 1-5, the second moving piece is a fourth sleeve 141, the fourth sleeve 141 is formed with a second internal thread in the axial direction, the outer side wall of the shell 110 is provided with a second external thread, and the second internal thread is engaged with the second external thread. Or the fourth sleeve 141 is formed with the second external thread in the axial direction, and the inner side wall of the shell 110 is provided with the second internal thread. In some embodiments, the rotation direction of the second internal thread and the first internal thread is opposite, and the length of the first internal thread is longer than the length of the second internal thread.

[0076] It can be understood that the second moving part can be the fourth sleeve 141. The fourth sleeve 141 is provided with a second internal thread in the axial direction, and the outer side wall of the shell 110 close to the opening 111 can be provided with a second external thread. Or the fourth sleeve 141 is formed with a second external thread in the axial direction, and the inner side wall of the shell 110 is provided with a second internal thread. The second external thread can be screwed in the second internal thread, so that by screwing the fourth sleeve 141, the position of the fourth sleeve 141 in the axial direction can be adjusted. And the rotation direction of the second internal thread and the first internal thread is opposite. In this way, when it is necessary to separate the drag plate body 120 and the moving assembly 130, the first sleeve 1311 is rotated in the third direction, and through the engagement of the first external thread and the first internal thread, the connecting rod 1312 is rotated and linearly moves in the first direction at the same time, and the connecting rod 1312 drives the second sleeve 1313 and the drag plate body 120 to rotate and linearly move in the first direction at the same time. Until the drag plate body 120 abuts against the fourth sleeve 141, and the drag plate body 120 is connected to the second connecting piece 142. Due to the rotation of the drag plate body 120, the fourth sleeve 141 is driven to rotate in the third direction through the second connecting piece 142, and because the rotation direction of the second internal thread and the first internal thread is opposite, when the fourth sleeve 141 rotates in the third direction, it linearly moves in the second direction, thereby driving the drag plate body 120 to move in the second direction, and applying greater thrust pressure to the drag plate body 120, so that the drag plate body 120 can be quickly separated from the first connecting piece 132, thereby reducing the separation stroke of the drag plate body 120, thereby more reasonably using the space in the shell 110, shortening the overall height of the shell 110, facilitating the space layout of the overall cleaning robot, and improving the space utilization rate.

[0077] In some examples, as shown in FIGS. 1-5, the second connecting piece 142 includes a clamping part and a matching part, and the clamping part is clamped to the matching part. In some embodiments, when the clamping part is arranged at one end of the fourth sleeve 141 facing the drag plate body 120, the matching part is arranged at one end of the drag plate body 120 facing the fourth sleeve 141. When the matching part is arranged at one end of the fourth sleeve 141 facing the drag plate body 120, the clamping part is arranged at one end of the drag plate body 120 facing the fourth sleeve 141.

[0078] It can be understood that the second connecting piece 142 can be provided with a clamping part and a matching part. The tray body 120 can be connected to the fourth sleeve 141 through the cooperation of the clamping part and the matching part. In some embodiments, the clamping part is arranged at one end of the fourth sleeve 141 facing the tray body 120, and the matching part is arranged at one end of the tray body 120 facing the fourth sleeve 141. In some embodiments, the matching part is arranged at one end of the fourth sleeve 141 facing the tray body 120, and the clamping part is arranged at one end of the tray body 120 facing the fourth sleeve 141. In this way, when the moving assembly 130 rotates the tray body 120 and moves it to abut against the fourth sleeve 141 in the first direction, the clamping part can be clamped to the matching part, so that the tray body 120 is connected to the fourth sleeve 141, so that the fourth sleeve 141 and the tray body 120 rotate in the same direction while driving the tray body 120 to move in the second direction.

[0079] Exemplarily, the clamping part can be a screw, and the matching part can be a screw seat. When the moving assembly 130 rotates the tray body 120 and moves it to abut against the fourth sleeve 141 in the first direction, the screw is screwed into the screw seat under the action of the rotating force, so that the tray body 120 is connected to the fourth sleeve 141.

[0080] In some examples, as shown in FIGS. 1-5, the center axes of the first sleeve 1311, the second sleeve 1313, the third sleeve 122, and the fourth sleeve 141 are arranged in line.

[0081] It can be understood that arranging the center axes of the first sleeve 1311, the second sleeve 1313, the third sleeve 122, and the fourth sleeve 141 in line can ensure coaxial rotation, avoid deviation, improve rotation stability, and ensure that the second sleeve 1313, the fourth sleeve 141, and the tray body 120 can move linearly along the axis of the rotating shaft, avoid skewing, and improve reliability.

[0082] In some examples, as shown in FIGS. 1-5, the tray structure 100 further includes a reset piece connected to the fourth sleeve 141 and the housing 110, respectively, for restoring the fourth sleeve 141 to the initial position when the tray body 120 and the moving assembly 130 are separated.

[0083] It can be understood that the mop plate structure 100 is further provided with a reset member. In some embodiments, the reset member can be connected to the fourth sleeve 141 and the shell 110. By providing the reset member, in the case that the mop plate body 120 and the moving assembly 130 are separated, the reset member can drive the fourth sleeve 141 to move in the first direction to move away from the mop plate body 120 until the fourth sleeve 141 returns to the initial position. In this way, it can be ensured that after the mop plate body 120 and the moving assembly 130 are separated, the fourth sleeve 141 does not interfere, facilitating cleaning or taking the mop plate body 120.

[0084] In some examples, as shown in FIGS. 1-5, the above-mentioned mop plate structure 100 further comprises a transmission shaft 160 connected to the first sleeve 1311 away from the first connecting member 132. The transmission shaft 160 is connected to the output shaft of the driving member.

[0085] It can be understood that the mop plate structure 100 can also be provided with a transmission shaft 160. In some embodiments, the transmission shaft 160 is provided at the end of the first sleeve 1311 away from the first connecting member 132. And the transmission shaft 160 is connected to the output shaft of the driving member, and the power of the driving member is transmitted to the first sleeve 1311 through the transmission shaft 160, so that the first sleeve 1311 can rotate relative to the shell 110, realizing the automatic rotation of the first sleeve 1311. And by controlling the rotation direction of the output shaft of the driving member, the rotation direction of the first sleeve 1311 can be adjusted, so as to control the linear motion direction of the second sleeve 1313, to control the automatic connection and automatic separation of the mop plate body 120 and the moving assembly 130, improve the degree of automation, and improve the user experience.

[0086] In some examples, as shown in FIGS. 1-5, the above-mentioned mop plate structure 100 further comprises a bearing 170 sleeved on the transmission shaft 160 and / or the first sleeve 1311.

[0087] It can be understood that the bearing 170 is sleeved on the transmission shaft 160 and the first sleeve 1311. By limiting the axial movement of the first sleeve 1311, the rotation smoothness of the first sleeve 1311 can be improved, the friction between the first sleeve 1311 and the shell 110 can be reduced, the rotation loss can be reduced, and the service life can be prolonged.

[0088] In some examples, as shown in FIGS. 1-5, the above-mentioned reset member is a torsion spring 180.

[0089] It can be understood that the reset member can be a torsion spring 180. One end of the torsion spring 180 is connected to the fourth sleeve 141, and the other end is connected to the shell 110. In this way, when the squeegee body 120 drives the fourth sleeve 141 to rotate in the third direction, the fourth sleeve 141 drives the squeegee to move linearly in the second direction, thereby exerting a rotational tensile force on the torsion spring 180. After the squeegee body 120 is separated from the first connecting member 132, the squeegee body 120 stops rotating. At this time, in order to restore the deformation, the torsion spring 180 exerts a rotational torque on the fourth sleeve 141, so that the fourth sleeve 141 rotates in the fourth direction, which is opposite to the third direction in some embodiments. Due to the opposite rotation directions of the second internal thread and the first internal thread, the fourth sleeve 141 moves linearly in the first direction to move away from the squeegee body 120 and returns to the initial position.

[0090] According to a second aspect of the embodiments of the present application, a cleaning robot is provided, which comprises the squeegee structure 100 according to any one of the above technical solutions, and thus has all the beneficial effects of the squeegee structure 100, which will not be repeated here.

[0091] According to a third aspect of the embodiments of the present application, as shown in FIG. 6, a cleaning system 100 is provided, which comprises the cleaning robot 200 according to any one of the above technical solutions, and a cleaning base station 300, wherein the cleaning robot can be parked on a base 301 of the cleaning base station; and a fixing member 302 is configured to fix the squeegee body 120 to the base when the squeegee body 120 is separated from the moving assembly 130.

[0092] It can be understood that the cleaning system is provided with the cleaning robot according to any one of the above technical solutions, and thus has all the beneficial effects of the cleaning robot, which will not be repeated here. The cleaning system is also provided with a cleaning base station and a fixing member. In some embodiments, the cleaning base station is used to maintain the cleaning robot, to clean the cleaning member of the cleaning robot, and to clean the squeegee body removed from the squeegee structure 100. The fixing member can be arranged on the base of the cleaning base station, and after the squeegee of the squeegee structure 100 is separated from the moving assembly 130, the fixing member can fix the squeegee body to the base, so that the squeegee body 120 does not move during the cleaning process, which affects the cleaning effect and improves the stability.

[0093] In some examples, as shown in FIGS. 2 and 3, the fixing member comprises a second magnetic member 210 arranged on the base, and an end of the squeegee body 120 facing the base is provided with a placing groove, and the second magnetic member 210 is inserted into the placing groove.

[0094] It can be understood that the fixing member can be provided with the second magnetic member 210 and the second metal member. In some embodiments, the second magnetic member 210 can be arranged on the end face of the base towards the cleaning robot, and one end of the mop body 120 towards the base can be provided with a placing groove, and the second metal member can be arranged at the groove bottom and the groove wall of the placing groove. Under the influence of the magnetic force, the second magnetic member 210 can be inserted into the placing groove and attracted to the second metal member. In this way, on the one hand, when the mop body 120 and the moving assembly 130 are connected, the second magnetic member 210 always generates an attractive force on the second metal member to exert a pulling force on the mop body 120 towards the base. On the other hand, during the separation of the mop body 120 and the moving assembly 130, the pressing force exerted by the limiting member 140 on the mop body 120 and the pulling force exerted by the second magnetic member 210 on the mop body 120 towards the base can accelerate the separation speed of the mop body 120 and the moving assembly 130, thereby reducing the separation stroke of the mop body 120, more reasonably utilizing the space in the shell 110, shortening the overall height of the shell 110, facilitating the overall space layout of the cleaning robot, and improving the space utilization rate.

[0095] Exemplarily, when it is necessary to separate the mop body 120 and the moving assembly 130, the first sleeve 1311 is rotated in the third direction, and through the engagement of the first outer thread and the first inner thread, the connecting rod 1312 is rotated and linearly moves in the first direction at the same time, and the second sleeve 1313 and the mop body 120 are rotated and linearly move in the first direction at the same time. Until the mop body 120 abuts against the fourth sleeve 141, and the mop body 120 is connected to the second connecting member 142. Due to the rotation of the mop body 120, the fourth sleeve 141 is driven to rotate in the third direction through the second connecting member 142, and due to the opposite rotation direction of the second inner thread and the first inner thread, the fourth sleeve 141 rotates in the third direction and linearly moves in the second direction at the same time, thereby driving the mop body 120 to move in the second direction and exerting a greater pressing force on the mop body 120. At the same time, the elastic member 150 in the third sleeve 122 of the mop body 120 exerts a pulling force in the second direction on the connecting handle 123. Under the action of the resultant force in the second direction, the mop body 120 can be quickly separated from the first connecting member 132, thereby reducing the separation stroke of the mop body 120, more reasonably utilizing the space in the shell 110, shortening the overall height of the shell 110, facilitating the overall space layout of the cleaning robot, and improving the space utilization rate.

[0096] Exemplarily, the second magnetic member 210 can be trapezoidal, and the shorter side of the trapezoid faces the mop body 120. Correspondingly, the placing groove is also trapezoidal.
