[0072] In order to better understand the above technical solution, the technical solution of the embodiment of the present application is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiment of the present application and the specific features in the embodiment are detailed descriptions of the technical solution of the embodiment of the present application, rather than limitations on the technical solution of the present application. In the absence of conflict, the embodiment of the present application and the technical features in the embodiment can be combined with each other.

[0073] like Figures 1 to 5 As shown, according to the first aspect of the embodiment of the present application, a carriage structure 100 is proposed, including: a shell 110; a carriage body 120; a moving assembly 130, which is arranged in the above-mentioned shell 110, and the above-mentioned moving assembly 130 is used to be connected to the above-mentioned carriage body 120; a limiting member 140, which is arranged at one end of the above-mentioned shell 110 facing the above-mentioned carriage body 120; wherein, the direction of the above-mentioned carriage body 120 toward the above-mentioned shell 110 is set as the first direction, the above-mentioned moving assembly 130 is used to drive the above-mentioned carriage body 120 to move in the above-mentioned first direction, and the above-mentioned limiting member 140 is used to press the above-mentioned carriage body 120 to limit the above-mentioned carriage body 120 from continuing to move in the above-mentioned first direction, so that the above-mentioned carriage body 120 and the moving assembly 130 are separated.

[0074] It can be understood that compared to the prior art, the present invention has at least the following advantages: The platform structure 100 provided in the embodiment of the present application is provided with a housing 110, a platform body 120, a moving assembly 130, and a stopper 140. The housing 110 can be disposed within a cleaning robot, and the moving assembly 130 is disposed within the housing 110. The housing 110 protects the moving assembly 130, thereby improving the reliability and service life of the moving assembly 130. The stopper 140 can be disposed at one end of the housing 110 facing the platform body 120, and can limit the movement of the platform body 120 toward the housing 110. The platform body 120 can have an operating side. When the cleaning robot is performing a cleaning operation, the platform body 120 can be connected to the moving assembly 130 and wash and mop the object to be cleaned through the operating side. When the cleaning robot returns to the cleaning base station and needs to remove the carriage body 120, the moving assembly 130 can apply a pulling force to the carriage body 120 to drive the carriage body 120 to move, thereby cooperating with the stopper 140 to remove the carriage body 120 from the moving assembly 130. Specifically, assuming that the direction of the carriage assembly toward the housing 110 is a first direction, the moving assembly 130 can drive the carriage body 120 to move in the first direction until the carriage body 120 abuts the stopper 140. At this point, the moving assembly 130 continues to move in the first direction, while the carriage body 120 is blocked by the stopper 140. The stopper 140 continues to press against the carriage body 120 to limit its movement in the first direction, causing the distance between the moving assembly 130 and the carriage body 120 to gradually increase until the pressing force applied by the stopper 140 exceeds the pulling force of the moving assembly 130 on the carriage body 120, and the carriage body 120 and the moving assembly 130 separate. Such a configuration can realize the automation of the separation of the drag plate body 120 from the cleaning robot, reduce manual intervention, and improve user experience.

[0075] It should be noted that a movable space may be formed within the housing 110, and an opening 111 may be vertically defined at the bottom of the housing. The opening 111 is connected to the movable space. The movable assembly 130 may be disposed within the movable space of the housing and may be vertically movable toward or away from the opening 111. A stopper 140 may be disposed at the opening 111 of the housing 110 and protrude therefrom. With this arrangement, when the movable assembly 130 drives the carriage body 120 toward the opening 111 of the housing 110, the carriage body 120 is first blocked by the stopper 140 and prevented from further movement toward the opening 111 of the housing 110. This allows the carriage body 120 and the movable assembly 130 to separate, thereby reducing displacement of the carriage body 120 and optimizing the space design. This also reduces the distance the carriage body 120 falls after separation, improving protection for the carriage body 120 and extending its service life. For example, the limiting member 140 may be an integrated structure with the housing 110 .

[0076] In some examples, such as Figures 1 to 5 As shown, the moving assembly 130 includes: a first connecting member 132, to which the carriage body 120 is connected; a first moving member 131, which is disposed in the housing 110, and to which the carriage body 120 is connected via the first connecting member 132. The first moving member 131 is used to drive the carriage body 120 to move toward or away from the housing 110.

[0077] It will be appreciated that the moving assembly 130 may be provided with a first moving member 131 and a first connecting member 132. The carriage body 120 may be connected to the first moving member 131 via the first connecting member 132. The first moving member 131 may be installed within the housing 110 through the opening 111 of the housing 110. The first moving member 131 may drive the carriage body 120 toward or away from the housing 110 via the first connecting member 132. With this arrangement, a pulling force may be applied to the carriage body 120 via the first connecting member 132, causing the first moving member 131 to drive the carriage body 120 in the first direction until the carriage body 120 abuts against the stop member 140. Subsequently, the first moving member 131 continues to move in the first direction, and the carriage body 120 is subjected to the pressing force applied by the limiting member 140 and cannot continue to move in the first direction. Moreover, as the moving assembly 130 continues to move in the first direction, the pressing force applied by the limiting member 140 on the carriage body 120 exceeds the pulling force applied by the first connecting member 132 on the carriage body 120, causing the carriage body 120 and the first connecting member 132 to separate, thereby separating the carriage body 120 and the moving assembly 130.

[0078] For example, the first connecting member 132 can be configured as a snap-fit ​​member, and the platform body 120 can be connected to the movable assembly 130 via a snap-fit ​​connection. For example, the snap-fit ​​member can be provided with a pinch plate and a snap position. The pinch plate is provided on the platform body 120, and the snap position is provided on the movable assembly 130, wherein the pinch plate can be snapped into the snap position. After the platform body 120 is blocked by the limiter 140, the limiter 140 applies a pressing force to the platform body 120 to restrict movement of the platform body 120 in the first direction. As the movable assembly 130 continues to move in the first direction, the pressing force applied by the limiter 140 on the platform body 120 continuously increases until the pressing force exceeds the connecting tension of the snap-fit ​​member, causing the pinch plate and the snap position to separate, and the platform and movable assembly 130 to separate.

[0079] In some examples, such as Figures 1 to 5 As shown, the first moving member 131 includes: a first sleeve 1311, which is rotatably arranged in the shell 110, and a first internal thread is formed in the axial direction of the first sleeve 1311; a connecting rod 1312, one end of the connecting rod 1312 is provided with a first external thread, and the first external thread is engaged with the first internal thread; or one end of the connecting rod 1312 is provided with the first internal thread, and the first external thread is formed in the axial direction of the first sleeve 1311; a second sleeve 1313, the second sleeve 1313 is connected to the other end of the connecting rod 1312, the first connecting member 132 is arranged in the second sleeve 1313, and the drag plate body 120 can be connected to the second sleeve 1313.

[0080] It is understood that the first movable member 131 may be provided with a first sleeve 1311, a connecting rod 1312, and a second sleeve 1313. The first sleeve 1311 may be axially fixedly disposed within the housing 110 and rotatable relative to the housing 110. The first sleeve 1311 may be connected to a driving member, which drives the first sleeve 1311 to rotate. Furthermore, a first internal thread may be formed in the axial direction of the first sleeve 1311. The end of the connecting rod 1312 near the first sleeve 1311 may be provided with a first external thread, which may be screwed onto the first internal thread. Alternatively, the first sleeve 1311 may be provided with a first external thread in the axial direction, and the end of the connecting rod 1312 near the first sleeve 1311 may be provided with a first internal thread. This configuration allows the rotation of the thread to be converted into linear motion of the connecting rod 1312, making the distance control of the linear motion more precise. The direction and distance of the linear motion of the connecting rod 1312 can be controlled by controlling the rotation direction and number of revolutions of the first sleeve 1311. The second sleeve 1313 can be provided with a slot on the end facing the first sleeve 1311, into which the other end of the connecting rod 1312 can be inserted. This allows the second sleeve 1313 to move linearly in sync with the connecting rod 1312. The first connecting member 132 can be disposed within the second sleeve 1313, into which the carriage body 120 can be inserted. The first connecting member 132 is connected to the carriage body 120, enabling the second sleeve 1313 to drive the carriage body 120 in linear motion.

[0081] It is understood that when the carriage body 120 and the moving assembly 130 need to be separated, the first sleeve 1311 rotates in the third direction. The engagement of the first external thread and the first internal thread causes the connecting rod 1312 to move linearly in the first direction. The connecting rod 1312 then drives the second sleeve 1313 and the carriage body 120 to move linearly in the first direction until the carriage body 120 abuts the stopper 140. The first sleeve 1311 then 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 platform body 120 is unable to move in the first direction due to the pressing force of the limiting member 140. As the distance between the platform body 120 and the first connecting member 132 increases, the pressing force exerted by the limiting member 140 on the platform body 120 becomes greater than the pulling force of the first connecting member 132 on the platform body 120, causing the portion of the platform body 120 inserted into the second sleeve 1313 to be withdrawn from the second sleeve 1313.

[0082] Exemplarily, the first sleeve 1311 may be provided with an annular protrusion away from the opening 111 of the shell 110, and an annular groove may be provided at a corresponding position in the shell 110. The annular protrusion may be inserted into the annular groove, thereby limiting the freedom of the first sleeve 1311 in its axial direction, and the annular protrusion may rotate in the annular groove without affecting the rotational freedom of the first sleeve 1311.

[0083] In some examples, such as Figures 1 to 5 As shown, the above-mentioned drag plate body 120 includes: a plate body 121; a third sleeve 122, which is arranged at one end of the above-mentioned plate body 121 facing the above-mentioned shell 110 along the height direction of the above-mentioned plate body 121; a connecting handle 123, one end of the above-mentioned connecting handle 123 is arranged on the above-mentioned third sleeve 122, and the other end is used to be connected to the above-mentioned second sleeve 1313 through the above-mentioned first connecting member 132.

[0084] As will be understood, the platform body 120 is provided with a plate 121, a third sleeve 122, and a connecting handle 123. A cleaning member may be provided at the end of the plate 121 facing away from the moving assembly 130 to clean the floor. The end of the plate 121 facing the housing 110 may be configured to abut against the stopper 140. The third sleeve 122 may be provided at the end of the plate 121 facing the housing 110, with the opening of the third sleeve 122 facing the opening 111 of the housing 110. One end of the connecting handle 123 may be inserted into the third sleeve 122, and the other end of the connecting handle 123 may be inserted into the second sleeve 1313 via the first connecting member 132.

[0085] It is understood that the third sleeve 122 can be disposed in the middle of the end of the plate 121 facing the housing 110. This allows the plate 121 on both sides of the third sleeve 122 to be of equal size, thereby ensuring that the top pressure exerted by the stopper 140 on the plate 121 on both sides of the third sleeve 122 is balanced, ensuring balanced force and preventing tilting.

[0086] In some examples, such as Figures 1 to 5 As shown, the first connecting member 132 includes: a first magnetic member 1321 and a first metal member 1322; wherein, the first magnetic member 1321 is arranged on the inner wall of the second sleeve 1313, and the first metal member 1322 is arranged on the end of the connecting handle 123 facing the second sleeve 1313; or the first magnetic member 1321 is arranged on the end of the connecting handle 123 facing the second sleeve 1313, and the first metal member 1322 is arranged on the inner wall of the second sleeve 1313; or the first magnetic member 1321 is respectively arranged on the end of the connecting handle 123 facing the second sleeve 1313, and the inner wall of the second sleeve 1313.

[0087] It is understood that the first connecting member 132 may be provided with a first magnetic member 1321 and a first metal member 1322. The connecting handle 123 may be connected to the second sleeve 1313 by the magnetic force of the first magnetic member 1321. Specifically, the first magnetic member 1321 may be provided on the inner wall of the second sleeve 1313 facing the connecting handle 123, and the first metal member 1322 may be provided on the end of the connecting handle 123 facing the second sleeve 1313. The first metal member 1322 is attracted to the first magnetic member 1321 by magnetic force to connect the connecting handle 123 to the second sleeve 1313. Alternatively, the first metal member 1322 may be provided on the inner wall of the second sleeve 1313 facing the connecting handle 123, and the first magnetic member 1321 may be provided on the end of the connecting handle 123 facing the second sleeve 1313. The first metal part 1322 is attracted to the first magnetic part 1321 by magnetic force to connect the connecting handle 123 to the second sleeve 1313. Alternatively, two first magnetic parts 1321 may be provided. One of the first magnetic parts 1321 is provided at the end of the connecting handle 123 facing the second sleeve 1313, and the other first magnetic part 1321 is provided 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 suction force of the two first magnetic parts 1321. This arrangement makes the connection simple and quick, and the first connecting part 132 will not be worn, aged or deformed due to frequent use. The connection stability is ensured and the service life is extended.

[0088] It should be noted that when the carriage body 120 and the moving assembly 130 need to be separated, the suction force of the first magnetic member 1321 can cause the second sleeve 1313 to apply a pulling force to the connecting handle 123, allowing the first moving member 131 to drive the carriage body 120 to move in the first direction until the carriage body 120 abuts the stop member 140. Subsequently, the first moving member 131 continues to move in the first direction, but the carriage body 120 is prevented from moving in the first direction by the pressure exerted by the stop member 140. As the moving assembly 130 continues to move in the first direction, the second sleeve 1313 and the connecting handle 123 gradually separate. As the distance between the first magnetic member 1321 and the carriage body 120 increases, the suction force decreases, causing the pressure exerted by the stop member 140 on the carriage body 120 to exceed the suction force of the first magnetic member 1321, thereby ensuring that the carriage body 120 can be smoothly and stably separated from the moving assembly 130.

[0089] In some examples, such as Figures 1 to 5 As shown, the drag plate structure 100 further includes an elastic member 150 connected between the third sleeve 122 and the connecting handle 123 .

[0090] It will be appreciated that the carriage structure 100 is further provided with an elastic member 150. Specifically, the elastic member 150 can be disposed within the third sleeve 122 along the axis 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 axis of the third sleeve 122. With this arrangement, when the carriage body 120 and the movable assembly 130 are connected, the connecting handle 123 can be extended from the third sleeve 122 under the influence of magnetic force, with the extended portion connected to the inner bottom wall of the second sleeve 1313. At this time, the elastic member 150 is stretched by the tensile force. When the carriage body 120 and the moving assembly 130 are separated, the rebound of the elastic member 150 exerts a pulling force on the connecting handle 123 away from the second sleeve 1313. Combined with the pressing force exerted by the stopper 140 on the carriage body 120, the connecting handle 123 can be quickly separated from the second sleeve 1313. The elastic member 150 also drives the connecting handle 123 toward the inside of the third sleeve 122, improving disassembly speed and stability. Furthermore, the increased separation speed reduces the travel of the second sleeve 1313, thereby more effectively utilizing the space within the housing 110 and shortening the overall height of the housing 110. This facilitates the overall spatial layout of the cleaning robot and improves space utilization.

[0091] In some examples, the stroke of the carriage body 120 driven by the first movable member 131 is greater than the sum of the dimensions of the third sleeve 122 and the connecting handle 123 located in the second sleeve 1313; wherein, when the limiting member 140 presses the carriage body 120, the first movable member 131 continues to move in the first direction until the other end of the connecting handle 123 is separated from the second sleeve 1313.

[0092] It will be appreciated that when the first sleeve 1311 rotates, the threaded connection between the connecting rod 1312 and the first sleeve 1311 converts the rotation into linear motion of the connecting rod 1312, thereby driving the carriage body 120 toward or away from the opening 111 of the housing 110 via the first connecting member 132. The travel distance of the carriage body 120 driven by the first moving member 131 is greater than the sum of the dimensions of the third sleeve 122 and the connecting handle 123 within the second sleeve 1313. With this arrangement, rotation of the first sleeve 1311 in one direction causes the connecting rod 1312 to move vertically upward, driving the carriage body 120 toward the opening 111 of the housing 110 via the first connecting member 132. During this movement, the carriage body 120 is first blocked by the stop member 140, preventing it from continuing to move toward the opening 111 of the housing 110. The first sleeve 1311 continues to rotate, causing the connecting rod 1312 to apply an upward pulling force to the carriage body 120 through the first connecting member 132. When the pulling force is greater than the connecting force of the first connecting member 132 on the connecting handle 123 of the carriage body 120, the connecting handle 123 and the connecting rod 1312 separate, thereby separating the carriage body 120 from the moving assembly 130.

[0093] In some examples, such as Figures 1 to 5 As shown, the above-mentioned limiting member 140 includes: a second movable member, which is provided on the outer wall of the above-mentioned shell 110, and the above-mentioned second movable member can move along the outer wall of the above-mentioned shell 110; a second connecting member 142, which is used to connect the above-mentioned carriage body 120 to the above-mentioned second movable member; wherein, when the above-mentioned limiting member 140 presses the above-mentioned carriage body 120, the above-mentioned movable assembly 130 continues to move in the above-mentioned first direction, and the above-mentioned second movable member presses the above-mentioned carriage body 120 and moves in the second direction until the above-mentioned carriage body 120 and the above-mentioned movable assembly 130 are separated, and the above-mentioned first direction and the above-mentioned second direction are opposite.

[0094] It is understood that the limiting member 140 may be provided with a second movable member and a second connecting member 142. Specifically, the second movable member may be provided on the outer wall of the housing 110 near the opening 111, and the second movable member may be movable along the outer wall of the housing 110 toward or away from the opening 111 of the housing 110. Furthermore, the second movable member may be connected to the carriage body 120 via the second connecting member 142. With this arrangement, during the separation of the carriage body 120 and the movable assembly 130, after the movable assembly 130 drives the carriage body 120 to move in the first direction, causing the carriage body 120 to abut against the limiting member 140, the second connecting member 142 is connected to the carriage body 120. As the movable assembly 130 continues to move in the first direction, the second movable member may press against the carriage body 120, and the second movable member and the carriage body 120 may move together in the second direction until the carriage body 120 and the movable assembly 130 separate. By providing a second movable member and the movement directions of the second movable member and the first movable member 131 are opposite, while the height dimensions of each component remain unchanged, it is equivalent to increasing the separation stroke of the carriage body 120, improving the separation speed of the carriage body 120, and reducing the separation stroke of the carriage body 120, thereby more rationally utilizing the space within the shell 110, shortening the overall height of the shell 110, facilitating the overall spatial layout of the cleaning robot, and improving space utilization.

[0095] In some examples, such as Figures 1 to 5 As shown, the second moving part is a fourth sleeve 141, a second internal thread is formed in the axial direction of the fourth sleeve 141, the outer 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 second external thread is formed in the axial direction of the fourth sleeve 141, and the inner wall of the shell 110 is provided with the second internal thread; wherein, the second internal thread and the first internal thread have opposite rotation directions, and the length of the first internal thread is longer than the length of the second internal thread.

[0096] It is understood that the second movable member may be a fourth sleeve 141. A second internal thread may be provided along the axis of the fourth sleeve 141, and a second external thread may be provided on the outer wall of the housing 110 near the opening 111. Alternatively, a second external thread may be formed along the axis of the fourth sleeve 141, and a second internal thread may be provided on the inner wall of the housing 110. The second external thread can be screwed onto the second internal thread, thereby adjusting the axial position of the fourth sleeve 141 by screwing the fourth sleeve 141. Furthermore, the second internal thread and the first internal thread have opposite rotation directions. With this arrangement, when the carriage body 120 and the movable assembly 130 need to be separated, the first sleeve 1311 is rotated in the third direction. The engagement of the first external thread and the first internal thread causes the connecting rod 1312 to rotate while simultaneously performing linear motion in the first direction. The connecting rod 1312 then drives the second sleeve 1313 and the carriage body 120 to rotate while simultaneously performing linear motion in the first direction. Until the carriage body 120 abuts against the fourth sleeve 141 and the carriage body 120 is connected to the second connecting member 142. Due to the rotation of the carriage body 120, the fourth sleeve 141 is driven to rotate in the third direction via the second connecting member 142. Since the second internal thread and the first internal thread have opposite rotation directions, the fourth sleeve 141 rotates in the third direction and performs linear motion in the second direction, thereby driving the carriage body 120 to move in the second direction and applying greater pressing force to the carriage body 120, allowing the carriage body 120 to quickly separate from the first connecting member 132, thereby reducing the separation distance of the carriage body 120. This makes more rational use of the space within the housing 110, shortens the overall height of the housing 110, facilitates the overall spatial layout of the cleaning robot, and improves space utilization.

[0097] In some examples, such as Figures 1 to 5 As shown, the second connecting member 142 includes: a clamping portion and a matching portion, and the clamping portion is clamped to the matching portion; wherein, when the clamping portion is provided at the end of the fourth sleeve 141 facing the carriage body 120, the matching portion is provided at the end of the carriage body 120 facing the fourth sleeve 141; when the matching portion is provided at the end of the fourth sleeve 141 facing the carriage body 120, the clamping portion is provided at the end of the carriage body 120 facing the fourth sleeve 141.

[0098] It is understood that the second connecting member 142 may be provided with a snap-fitting portion and a mating portion. The snap-fitting portion and the mating portion cooperate to connect the carriage body 120 to the fourth sleeve 141. Specifically, if the snap-fitting portion is provided at the end of the fourth sleeve 141 facing the carriage body 120, the mating portion is provided at the end of the carriage body 120 facing the fourth sleeve 141; if the mating portion is provided at the end of the fourth sleeve 141 facing the carriage body 120, the snap-fitting portion is provided at the end of the carriage body 120 facing the fourth sleeve 141. With this arrangement, when the moving assembly 130 drives the carriage body 120 to rotate and move in the first direction until it abuts the fourth sleeve 141, the snap-fitting portion can snap into the mating portion, thereby connecting the carriage body 120 to the fourth sleeve 141. This allows the fourth sleeve 141 and the carriage body 120 to rotate in the same direction while driving the carriage body 120 to move in the second direction.

[0099] For example, the engaging portion may be a screw-knob and the mating portion may be a screw-knob position. When the moving assembly 130 drives the carriage body 120 to rotate and move in the first direction until it abuts against the fourth sleeve 141, the screw-knob is screwed into the screw-knob position under the action of the rotational force, thereby connecting the carriage body 120 to the fourth sleeve 141.

[0100] In some examples, such as Figures 1 to 5 As shown, the central axes of the first sleeve 1311 , the second sleeve 1313 , the third sleeve 122 and the fourth sleeve 141 are collinearly arranged.

[0101] It can be understood that arranging the central axes of the first sleeve 1311, the second sleeve 1313, the third sleeve 122 and the fourth sleeve 141 in a collinear manner can ensure coaxial rotation, avoid deviation, improve rotation stability, and ensure that the second sleeve 1313, the fourth sleeve 141 and the carriage body 120 can perform linear motion along the axial direction of the rotating shaft, avoid skewness, and improve reliability.

[0102] In some examples, such as Figures 1 to 5 As shown, the carriage structure 100 further includes a restoring member connected to the fourth sleeve 141 and the housing 110 , respectively, for restoring the fourth sleeve 141 to its initial position when the carriage body 120 and the moving assembly 130 are separated.

[0103] It will be appreciated that the carriage structure 100 is also provided with a reset member. Specifically, the reset member may be connected to the fourth sleeve 141 and the housing 110. By providing the reset member, when the carriage body 120 and the movable assembly 130 are separated, the reset member can drive the fourth sleeve 141 to move in the first direction, away from the carriage body 120, until the fourth sleeve 141 returns to its initial position. This configuration ensures that after the carriage body 120 and the movable assembly 130 are separated, there is no interference from the fourth sleeve 141, facilitating cleaning or removal of the carriage body 120.

[0104] In some examples, such as Figures 1 to 5 As shown, the carriage structure 100 further includes a transmission shaft 160 connected to an end of the first sleeve 1311 away from the first connecting member 132 , and the transmission shaft 160 is used to be connected to an output shaft of a driving member.

[0105] It is understood that the carriage structure 100 may also be provided with a transmission shaft 160. Specifically, the transmission shaft 160 is disposed at the end of the first sleeve 1311 away from the first connector 132. The transmission shaft 160 is connected to the output shaft of the driver. The transmission shaft 160 transmits the driver's power to the first sleeve 1311, thereby enabling the first sleeve 1311 to rotate relative to the housing 110, achieving automatic rotation of the first sleeve 1311. Furthermore, by controlling the rotation direction of the driver's output shaft, the rotation direction of the first sleeve 1311 can be adjusted, thereby controlling the linear motion direction of the second sleeve 1313. This allows for automatic connection and disconnection between the carriage body 120 and the moving assembly 130, thereby improving the degree of automation and user experience.

[0106] In some examples, such as Figures 1 to 5 As shown, the carriage structure 100 further includes a bearing 170 sleeved on the transmission shaft 160 and / or the first sleeve 1311 .

[0107] It is understood that the bearing 170 is sleeved on the transmission shaft 160 and the first sleeve 1311. The bearing 170 limits the axial movement of the first sleeve 1311, thereby improving the rotational smoothness of the first sleeve 1311, reducing friction between the first sleeve 1311 and the housing 110, reducing rotational losses, and extending the service life.

[0108] In some examples, such as Figures 1 to 5 As shown, the above-mentioned reset member is a torsion spring 180.

[0109] It is 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 housing 110. With this arrangement, when the carriage body 120 drives the fourth sleeve 141 to rotate in the third direction, the fourth sleeve 141 drives the carriage to move linearly in the second direction, thereby applying a rotational tensile force to the torsion spring 180. After the carriage body 120 is separated from the first connecting member 132, the carriage body 120 stops rotating. At this time, to restore the deformation, the torsion spring 180 applies a rotational torsional force to the fourth sleeve 141, causing the fourth sleeve 141 to rotate in the fourth direction, which is opposite to the third direction. Because the second internal thread and the first internal thread have opposite rotational directions, the fourth sleeve 141 moves linearly in the first direction, away from the carriage body 120, and returns to its initial position.

[0110] According to the second aspect of the embodiment of the present application, a cleaning robot is proposed, comprising: a drag plate structure 100 as described in any one of the above technical solutions, and therefore has all the beneficial effects of the above drag plate structure 100, which will not be repeated here.

[0111] According to the third aspect of the embodiment of the present application, a cleaning system is proposed, including: a cleaning robot as described in any one of the above technical solutions; a cleaning base station, on which the cleaning robot can be parked; and a fixing member for fixing the tray body 120 to the base when the tray body 120 and the moving component 130 are separated.

[0112] It is understandable that the cleaning system is provided with a cleaning robot as described in any one of the above technical solutions, and therefore has all the beneficial effects of the above cleaning robots, which will not be repeated here. The cleaning system is also provided with a cleaning base station and a fixing part. Among them, the cleaning base station is used to maintain the cleaning robot to clean the cleaning parts of the cleaning robot and to clean the drag plate body removed from the drag plate structure 100. The fixing part can be provided on the base of the cleaning base station. After the drag plate and the moving component 130 of the drag plate structure 100 are separated, the drag plate body can be fixed to the base by the fixing part, so that during the process of cleaning the drag plate body 120, the drag plate body 120 will not move, affecting the cleaning effect, and improving stability.

[0113] In some examples, such as Figure 2 and Figure 3 As shown, the above-mentioned fixing part includes: a second magnetic part 210, which is arranged on the above-mentioned base, and the above-mentioned drag plate body 120 has a placement groove at one end facing the above-mentioned base, and the above-mentioned second magnetic part 210 is used to be inserted into the above-mentioned placement groove; a second metal part, which is arranged at the bottom of the above-mentioned placement groove.

[0114] It is understood that the fixing member may be provided with a second magnetic member 210 and a second metal member. The second magnetic member 210 may be disposed on the end surface of the base facing the cleaning robot, and a placement slot may be defined on the end of the carriage body 120 facing the base. The second metal member may be disposed at the bottom and walls of the placement slot. Under the influence of magnetic force, the second magnetic member 210 may be inserted into the placement slot and attracted to the second metal member. With this arrangement, when the carriage body 120 and the moving assembly 130 are connected, the second magnetic member 210 constantly exerts an attractive force on the second metal member, thereby applying a pulling force on the carriage body 120 toward the base. On the other hand, during the separation of the carriage body 120 and the moving assembly 130, the top pressure applied by the limit member 140 to the carriage body 120 and the pulling force applied toward the base by the second magnetic member 210 to the carriage body 120 can speed up the separation speed of the carriage body 120 and the moving assembly 130, thereby reducing the separation stroke of the carriage body 120, thereby more rationally utilizing the space within the shell 110, shortening the overall height of the shell 110, facilitating the overall spatial layout of the cleaning robot, and improving space utilization.

[0115] For example, when the limiting member 140 is the fourth sleeve 141, the moving assembly 130 is provided with the first sleeve 1311 and the second sleeve 1313, and the elastic member 150 is provided, when it is necessary to separate the carriage body 120 and the moving assembly 130, the first sleeve 1311 rotates in the third direction. The engagement of the first external thread and the first internal thread causes the connecting rod 1312 to rotate and simultaneously perform linear motion in the first direction. The connecting rod 1312 then drives the second sleeve 1313 and the carriage body 120 to rotate and simultaneously perform linear motion in the first direction until the carriage body 120 abuts the fourth sleeve 141 and is connected to the second connecting member 142. The rotation of the carriage body 120 drives the fourth sleeve 141 in the third direction via the second connecting member 142. Since the second internal thread and the first internal thread have opposite rotational directions, the fourth sleeve 141 rotates in the third direction, performing linear motion in the second direction. This, in turn, drives the carriage body 120 in the second direction and applies greater pressure to the carriage body 120. Simultaneously, the elastic member 150 within the third sleeve 122 of the carriage body 120 applies a pulling force in the second direction to the connecting handle 123. The combined force in the second direction allows the carriage body 120 to quickly separate from the first connecting member 132, thereby reducing the distance traveled by the carriage body 120. This allows for more efficient use of the space within the housing 110, shortening the overall height of the housing 110, facilitating the overall spatial layout of the cleaning robot, and improving space efficiency.

[0116] For example, the second magnetic member 210 may be trapezoidal in shape, with the shorter side of the trapezoid facing the carriage body 120. Correspondingly, the placement slot is also trapezoidal in shape.
