Description

TECHNICAL FIELD

[0001] The present application relates to the field of floor cleaning robots, and in particular to a cover plate assembly, a cleaning piece and a floor cleaning robot. BACKGROUND

[0002] The cleaning piece is an important component of the floor cleaning robot, which includes a cover plate assembly and a roller. The cover plate assembly includes a housing for mounting the roller and a cover plate.

[0003] The cover plate can be fixedly connected with the housing, so that the housing can drive the cover plate to rotate relative to the roller, thereby enabling the cover plate to rotate between the front side of the roller along the direction of travel and the lower side of the roller. The cover plate located below the roller can reduce the possibility of the roller polluting the carpet.

[0004] The housing can be provided with fasteners (such as screws), so that the cover plate can be fixed with the housing through the fasteners, and the cover plate can be removed from the housing by removing the fasteners. However, this makes the disassembly process of the cover plate inconvenient. UTILITY MODEL CONTENT

[0005] The cover plate assembly, the cleaning piece and the floor cleaning robot provided by the embodiments of the present application solve the problem of inconvenient disassembly process of the cover plate.

[0006] The cover plate assembly provided by the embodiments of the present application comprises:

[0007] The housing comprises a first housing part and a second housing part oppositely arranged along a rotation axis, the first housing part and the second housing part are respectively used for mounting two ends of the roller along the axial direction, and the second housing part is used for extending and retracting the roller;

[0008] The cover plate is arranged on the housing;

[0009] The locking structure is movably arranged on the first housing part; when the locking structure is in a first state, the locking structure fixes the cover plate;

[0010] When the locking structure is in a second state, the locking structure releases the cover plate, and the cover plate can rotate relative to the housing about the rotation axis.

[0011] By adopting the above technical solution, the locking structure has the first state and the second state relative to each other. When the locking structure is in the first state, the locking structure can fix the cover plate, so that the cover plate is relatively fixed with the housing to realize the installation of the cover plate. In addition, the housing can drive the cover plate to rotate between the front side of the roller along the direction of travel and the lower side of the roller. The cover plate located below the roller can reduce the possibility of the roller polluting the carpet.

[0012] When the locking structure is in the second state, the locking structure can release the cover plate, so that the cover plate can rotate relative to the shell around the rotation axis, thereby adjusting the position of the cover plate, so that the cover plate can be detached from the shell to realize the disassembly process of the cover plate.

[0013] Compared with the related art, the cover plate assembly in the embodiment of the present application can realize the connection and separation of the cover plate and the shell by adjusting the state of the locking structure, so that the disassembly process of the cover plate is more convenient without the need to set fasteners or other connection structures on the cover plate and the shell.

[0014] In addition, in the related art, the locking structure is located on the side of the drum extending out, however, when the side where the locking structure is located is close to an obstacle (such as a wall), the locking structure will first contact the wall, so that a larger gap is generated between the end of the drum close to the locking structure and the wall, and the drum is difficult to clean the gap between the locking structure and the wall, which makes the cleaning blind area between the drum and the locking structure difficult to clean.

[0015] In the embodiment of the present application, the locking structure is arranged on the first shell part, when the end of the drum away from the locking structure extends out from the second shell part and approaches the obstacle, the locking structure is located on the side of the drum away from the obstacle, so that the locking structure does not increase the distance between the drum and the obstacle, thereby reducing the area of the cleaning blind area between the locking structure and the drum, and improving the cleaning effect of the sweeping robot.

[0016] In some possible implementations, the first shell part is provided with a containing groove, and an opening of the containing groove faces away from the second shell part;

[0017] The locking structure is movably arranged in the containing groove in a first direction, and the first direction is perpendicular to the rotation axis.

[0018] In this way, by arranging the containing groove on the first shell part, the opening of the containing groove faces away from the second shell part. The locking structure is movably arranged in the containing groove in the first direction, so that at least part of the locking structure can be accommodated in the containing groove, the width of the locking structure extending out of the opening in the rotation axis direction is reduced, and the width of the cleaning blind area between the locking structure and the drum in the rotation axis direction is reduced.

[0019] In addition, the first direction is perpendicular to the rotation axis, so that the moving direction of the locking structure is perpendicular to the rotation axis, thereby further reducing the possibility of the locking structure extending out of the first shell part in the rotation axis direction, and reducing the length of the cover plate assembly in the rotation axis direction.

[0020] In some possible embodiments, the locking structure comprises a communication portion and a blocking portion which are arranged at intervals along the first direction;

[0021] When the locking structure is in the first state, the locking structure is in a first position, and the locking structure fixes the cover plate through the blocking portion;

[0022] When the locking structure is in the second state, the locking structure is in a second position, and the cover plate can rotate relative to the shell through the communication portion.

[0023] In this way, when the locking structure is in the first state, the locking structure can be in the first position, and the locking structure can fix the cover plate through the blocking portion, so that the cover plate is relatively fixed with the shell.

[0024] When the locking structure is in the second state, the locking structure is in the second position, and the cover plate can rotate relative to the shell through the communication portion, so that the cover plate rotates between the front side of the roller along the advancing direction and the lower side of the roller, and the cover plate can be fixed at the front side of the roller along the advancing direction and the lower side of the roller through the locking structure.

[0025] When it is necessary to adjust the position of the cover plate, the locking structure can be slid in the accommodating groove along the first direction, so that the locking structure is in the second position, the locking structure can correspond to the cover plate through the communication portion, and the cover plate can rotate relative to the shell through the communication portion, so that the cover plate can be rotated to the front side of the roller along the advancing direction or the lower side of the roller.

[0026] Then, the locking structure can be slid in the accommodating groove along the first direction, so that the locking structure is in the first position, and the locking structure fixes the cover plate through the blocking portion, so that the cover plate can be fixed with the shell to achieve adjustment of the position of the cover plate.

[0027] In some possible embodiments, the first shell portion is provided with a rotating cavity; and at least a part of the cover plate can be arranged in the rotating cavity and rotate around the rotating axis;

[0028] When the locking structure is in the first position, the blocking portion extends into the rotating cavity; and when the locking structure is in the second position, the communication portion extends into the rotating cavity.

[0029] In this way, when the locking structure is in the first position, the blocking portion extends into the rotating cavity, so that the blocking portion can be used to abut against the cover plate, so that the cover plate can be limited to rotate in the rotating cavity through the blocking portion, and the cover plate can be relatively fixed with the shell.

[0030] When the locking structure is in the second position, the communication part extends into the rotating cavity, so that the communication part can be arranged opposite to the cover plate, and the communication part does not interfere with the rotation of the cover plate in the rotating cavity, thereby enabling the cover plate to rotate around the rotation axis in the rotating cavity through the communication part of the locking structure.

[0031] In some possible embodiments, the cover plate is provided with a limiting piece, which is arranged in the rotating cavity and can rotate around the rotation axis;

[0032] The communication part comprises a communication opening, and when the locking structure is in the second position, the communication opening can be used by the limiting piece.

[0033] In this way, when the locking structure is in the second position, the communication part extends into the rotating cavity, so that the communication part can be arranged opposite to the cover plate, and the communication opening of the communication part is in communication with the rotating cavity.

[0034] When the limiting piece of the cover plate rotates around the rotation axis in the rotating cavity, the limiting piece of the cover plate can rotate through the communication opening, so that the communication opening does not block the rotation of the limiting piece.

[0035] In some possible embodiments, the first shell part is provided with a movable opening facing downward, which is in communication with the rotating cavity;

[0036] The limiting piece can enter the rotating cavity through the movable opening and move out of the rotating cavity through the movable opening.

[0037] In this way, when the locking structure is in the second position, the cover plate can rotate between the front side of the drum along the advancing direction and the lower side of the drum, and the movable opening facing downward is arranged in the first shell part, so that the limiting piece can enter the rotating cavity through the movable opening and move out of the rotating cavity through the movable opening, thereby ensuring the stability of the rotation of the cover plate.

[0038] In some possible embodiments, one of the second inner wall of the accommodating groove and the locking structure is provided with an adjusting part;

[0039] The other of the second inner wall of the accommodating groove and the locking structure is provided with a first fixing part and a second fixing part, and the first fixing part and the second fixing part are arranged at intervals along the first direction;

[0040] When the locking structure is in the first position, the adjusting part is connected with the first fixing part; and when the locking structure is in the second position, the adjusting part is connected with the second fixing part.

[0041] The second inner wall of the accommodating groove and one of the locking structures are provided with an adjusting part, and the other of the second inner wall of the accommodating groove and the locking structures are provided with a first fixing part and a second fixing part, and the adjusting part can be used in cooperation with the first fixing part and the second fixing part.

[0042] When the locking structure is in the first position, the adjusting part is connected with the first fixing part, and the locking structure can be relatively fixed with the first shell part. When the locking structure is in the second position, the adjusting part is connected with the second fixing part, and the locking structure can be relatively fixed with the first shell part.

[0043] In some possible implementation manners, the locking structure has a fixed end and a movable end along the first direction;

[0044] The fixed end is close to the rotation axis, and the movable end is away from the rotation axis.

[0045] During the sliding of the locking structure along the first direction in the accommodating groove, the movable end does not protrude out of the first shell part.

[0046] In this way, during the sliding of the locking structure along the first direction in the accommodating groove, the movable end does not protrude out of the first shell part, so that the possibility of increasing the overall volume of the cover plate assembly by the locking structure can be reduced, the area of the cleaning blind spot between the locking structure and the drum can be reduced, and the cleaning effect of the robot cleaner can be improved.

[0047] In some possible implementation manners, the locking structure has a fixed end and a movable end along the first direction;

[0048] The fixed end is close to the rotation axis, and the movable end is away from the rotation axis.

[0049] When the locking structure is in the first position, the movable end is arranged flush with the first shell part, and when the locking structure is in the second position, the movable end protrudes out of the first shell part.

[0050] In this way, during the sliding of the locking structure along the first direction in the accommodating groove, when the locking structure is in the first position, the movable end is arranged flush with the outer circumferential arc surface of the first shell part, and the movable end does not protrude out of the first shell part, so that the possibility of increasing the overall volume of the cover plate assembly by the locking structure can be reduced. When the locking structure is in the second position, the movable end protrudes out of the first shell part, so that the remaining part of the locking structure is located in the accommodating groove, and the possibility of the locking structure being separated from the accommodating groove can be reduced.

[0051] The embodiments of the present application also provide a cleaning piece, which comprises a drum and the cover plate assembly described in any one of the above.

[0052] One of the axial ends of the roller is rotatably arranged on the first shell part about the rotation axis, and the other axial end of the roller is rotatably arranged on the second shell part about the rotation axis.

[0053] Since the cleaning piece comprises any one of the cover plate assemblies described above, the cleaning piece has the advantages of any one of the cover plate assemblies described above, which can be specifically understood with reference to the related description above, and will not be described here again.

[0077] The specific embodiments of the present application have been shown by the above-described drawings, and will be described in more detail hereinafter. These drawings and textual descriptions are not intended to limit the scope of the concept of the present application by any means, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0078] As described in the background, the cleaning member is an important component of the robot, including the cover plate assembly and the roller. The cover plate assembly includes a shell for mounting the roller, and a cover plate movably arranged on the shell. The cover plate assembly can include a locking structure movably arranged on the shell, and the locking structure can be arranged on the front side of the roller along the direction of travel.

[0079] The locking structure can be used to fix the cover plate with the shell, so as to reduce the possibility of rotation of the cover plate relative to the shell when the robot is in a working state. For example, when cleaning the ground such as ceramic tiles by the roller, the shell can drive the cover plate to rotate to the front side of the roller along the direction of travel, so that the bottom of the roller can be in contact with the ceramic tiles.

[0080] When cleaning a dry cleaning environment such as a blanket by the robot, the shell can drive the cover plate to rotate to the lower side of the roller, so as to separate the roller from the blanket by the cover plate, so as to reduce the possibility of wetting the blanket by the roller.

[0081] In order to realize the dismounting process of the cover plate, a fastener (for example, a screw) can be arranged on the shell, so that the cover plate can be fixed with the shell through the fastener, and the cover plate can be dismounted from the shell by dismounting the fastener. However, this makes it necessary to dismount the fastener first before the cover plate can be fixed with or separated from the shell, which makes the dismounting process of the cover plate inconvenient.

[0082] The locking structure in the shell assembly is located at the side where the roller extends out. When the roller needs to extend out of the shell to clean the corner of the wall through the shell, the roller can extend out of the shell from the side where the locking structure is located. However, when the end of the roller close to the locking structure approaches the barrier such as the wall, the locking structure will first contact the wall, so that a large gap is generated between the end of the roller close to the locking structure and the wall, and the roller has difficulty in cleaning the gap between the locking structure and the wall, which makes a cleaning blind area between the roller and the locking structure that is difficult for the roller to clean.

[0083] To solve the above technical problems, the embodiments of the present application provide a cover plate assembly, a cleaning piece and a sweeping robot. In the cover plate assembly, the locking structure has opposite first and second states. When the locking structure is in the first state, the locking structure can fix the cover plate, so that the cover plate is relatively fixed with the shell to realize the mounting process of the cover plate and the shell. Moreover, the shell can drive the cover plate to rotate relative to the roller, and the cover plate located below the roller can reduce the possibility of the roller polluting the carpet. When the locking structure is in the second state, the locking structure can release the cover plate, so that the cover plate can rotate relative to the shell about the rotation axis, and the cover plate can be dismounted from the shell.

[0084] Compared with the related art that realizes the dismounting process of the cover plate through the fastener, the cover plate assembly in the embodiments of the present application can realize the connection and separation of the cover plate and the shell by adjusting the state of the locking structure, so that the fastener or other connecting structure does not need to be arranged on the cover plate and the shell, and the dismounting process of the cover plate is more convenient.

[0085] Moreover, in the related art, the locking structure is located at the side where the roller extends out. However, when the side where the locking structure is located approaches the barrier such as the wall, the locking structure will first contact the wall, so that a large gap is generated between the end of the roller close to the locking structure and the wall, and the roller has difficulty in cleaning the gap between the locking structure and the wall, which makes a cleaning blind area between the roller and the locking structure that is difficult for the roller to clean.

[0086] In the embodiment of the present application, the locking structure is arranged on the first shell part. When the roller extends from the second shell part and approaches the obstacle at the end away from the locking structure, the locking structure is located at the side of the roller away from the obstacle, so that the locking structure does not increase the distance between the roller and the obstacle, thereby reducing the area of the cleaning blind spot between the locking structure and the roller, and improving the cleaning effect of the robot.

[0087] The exemplary embodiments will be described in detail hereinbelow with examples shown in the drawings. In the following description, the same numbers in different drawings represent the same or similar elements unless otherwise represented. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they only represent examples of apparatuses and methods consistent with some aspects of the present application as detailed in the appended claims.

[0088] The technical solutions of the present application and how the technical solutions solve the above technical problems will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described again in some embodiments. The embodiments of the present application will be described below with reference to the drawings.

[0089] With reference to Figures 1-4 The embodiment of the present application provides a cover assembly, which comprises a shell 10. The shell 10 can comprise a first shell part 100 and a second shell part 400 arranged opposite along a rotation axis.

[0090] The first shell part 100 and the second shell part 400 are respectively used to mount two ends of a roller 500 in the axial direction, so that the roller 500 can rotate relative to the shell 10 around the rotation axis (i.e. the x direction in the figure). Figure 1 The second shell part 400 can be used to extend and retract the roller 500, so that the roller 500 can extend from the second shell part 400 to the shell 100 along the rotation axis.

[0091] When cleaning a surface to be cleaned (for example, the surface to be cleaned can be ceramic tiles or wooden floors, etc.) by the roller 500, the roller 500 can be rolled on the surface to be cleaned in a travel direction. The travel direction of the roller 500 can be arranged perpendicular to the rotation axis.

[0092] For example, the cover assembly can comprise a cover plate 200. The cover plate 200 can be movably arranged on the shell 10. When cleaning the ground environment such as ceramic tiles by the roller, the cover plate 200 can be rotated to the front side of the roller 500 in the travel direction, so that the bottom of the roller 500 can be in contact with the ceramic tiles.

[0093] And, when cleaning a dry cleaning environment such as a carpet by the cleaning robot, the cover plate 200 can be rotated to the lower side of the roller 500, so that the roller 500 can be separated from the carpet by the cover plate 200 to reduce the possibility of the roller 500 wetting the carpet.

[0094] In some possible embodiments, the cover plate assembly comprises a locking structure 300. The locking structure 300 is movably arranged on the first shell part 100, and the locking structure 300 is used to fix the cover plate 200, so that the cover plate 200 can be relatively fixed with the shell 10, thereby reducing the possibility of the cover plate 200 rotating relative to the shell 10 when the cleaning robot is in a working state.

[0095] For example, when the locking structure 300 is in a first state, the locking structure 300 can fix the cover plate 200, so that the cover plate 200 can be relatively fixed with the shell 10, and the shell 10 can drive the cover plate 200 to rotate around the rotation axis.

[0096] When the locking structure 300 is in a second state, the locking structure 300 releases the cover plate 200, so that the cover plate 200 can rotate relative to the shell 10 around the rotation axis, so that the cover plate 200 can be detached from the shell 10.

[0097] It should be noted that, compared with the way of realizing the cover plate dismounting process by the fastener in the related art, the cover plate assembly in the embodiment of the present application is arranged on the shell 10 by the movable locking structure 300, so that the locking structure 300 can have the relative first state and the second state, so that the connection and separation of the cover plate 200 and the shell 10 can be realized by adjusting the state of the locking structure 300, thereby eliminating the need for arranging the fastener and other connecting structures on the cover plate 200 and the shell 10, so that the dismounting process of the cover plate 200 is more convenient.

[0098] In some possible embodiments, the cover plate assembly can have a movable side and a fixed side arranged oppositely, the first shell part 100 can be located on the fixed side, and the second shell part 400 can be located on the movable side.

[0099] The roller 500 can extend from the movable side of the cover plate assembly, so that the roller 500 can extend from the second shell part 400, and the cooperation mode of the first shell part 100 and the locking structure 300 will not affect the movement process of the roller 500.

[0100] It should be noted that, when the locking structure 300 is located on the second shell part 400, the locking structure 300 needs to occupy part of the space of the second shell part 400, thereby compressing the movement space of the roller 500.

[0101] And, since the locking structure 300 needs to generate relative displacement relative to the second shell part 400, the locking structure 300 needs to further occupy part of the space of the second shell part 400, thereby further compressing the moving space and moving range of the roller 500.

[0102] For example, the locking structure 300 has opposite first and second states, when the locking structure is in the first state, the locking structure 300 can fix the cover plate 200, so that the cover plate 200 is relatively fixed with the shell 100, and the shell 10 can drive the cover plate 200 to rotate between the front side of the roller 500 and the lower side of the roller 500, and the cover plate 200 located below the roller 500 can reduce the possibility of the roller 500 polluting the carpet.

[0103] When the locking structure 300 is in the second state, the locking structure 300 can release the cover plate 200, so that the cover plate 200 rotates relative to the shell 10, thereby enabling the cover plate 200 to be detached from the shell 10 to realize the disassembly process of the cover plate 200.

[0104] When the locking structure 300 switches between the first state and the second state, the locking structure 300 needs to move relative to the second shell part 400, so that the assembly space required by the locking structure 300 is further increased, and the roller 500 needs to extend and move in and out of the second shell part 400, the locking structure 300 will affect the moving space and moving range of the roller 500, so that the moving process of the roller 500 is easily affected by the locking structure 300 arranged on the second shell part 400, thereby making the cleaning effect of the roller 500 on the cleaning blind area poor.

[0105] It should be noted that the locking structure 300 is located on the side where the roller 500 extends, for example, the locking structure 300 is located on the second shell part 400. When the side where the second shell part 400 of the shell assembly is close to an obstacle (such as a wall), the locking structure 300 will first contact the obstacle, so that a larger gap is generated between the end of the roller 500 close to the locking structure and the obstacle, and the roller is difficult to clean the gap between the locking structure 300 and the obstacle, which makes the cleaning blind area between the roller 500 and the locking structure 300 difficult to clean.

[0106] In the embodiments of the present application, the locking structure 300 is located on the fixed side of the cover plate assembly, so that the moving process of the locking structure 300 will not affect the moving and extending process of the roller 500, and the cleaning effect of the sweeping robot on the ground is improved.

[0107] Reference Figures 1-4 In some possible implementations, the number of locking structures 300 can be set to one, and the locking structure 300 is arranged on the first shell part 100, so that the structure of the cover plate assembly is simpler.

[0108] Alternatively, the number of the locking structure 300 can be set to be multiple, and the multiple locking structures 300 can include a first locking structure and a second locking structure. The first locking structure and the second locking structure can be movably arranged on the first shell part 100, and the first locking structure and the second locking structure are different in position.

[0109] By setting the number of the locking structure 300 to be multiple, the first locking structure and the second locking structure can be used to fix the cover plate 200 and the shell 10, so that the connection between the cover plate 200 and the shell 10 is more stable, and the possibility of the cover plate 200 rotating relative to the shell 10 is reduced.

[0110] It is easy to understand that when the number of the locking structure 300 is multiple, the multiple locking structures 300 can be arranged symmetrically relative to the rotation axis, so that the multiple locking structures 300 can be used to fix different positions of the cover plate 200.

[0111] Hereinafter, the connection mode between the locking structure 300 and the first shell part 100 will be described by taking the number of the locking structure 300 as one as an example.

[0112] In some possible implementation modes, the first shell part 100 can be provided with a containing groove 110, and the containing groove 110 can be used to accommodate at least part of the locking structure 300.

[0113] For example, the locking structure 300 can be movably arranged in the containing groove 110 along a first direction, and the first direction is perpendicular to the rotation axis.

[0114] When the locking structure 300 is in the first position, the locking structure 300 can be in a first state, the locking structure 300 fixes the cover plate 200, so that the shell 10 can drive the cover plate 200 to rotate to the front side of the roller 500 along the advancing direction or below the roller 500, and the cover plate 200 located below the roller 500 can reduce the possibility of the roller 500 polluting the carpet.

[0115] When the locking structure 300 is in the second position, the locking structure 300 can be in a second state, the locking structure 300 releases the cover plate 200, so that the cover plate 200 can move relative to the first shell part 100, thereby realizing the disassembly process of the cover plate 200.

[0116] The first position and the second position can be along the first direction (i.e. Figure 1The locking structure 300 is arranged in the accommodating groove 110 and is movable in the first direction in the accommodating groove 110, so that the locking structure 300 can move between the first position and the second position in the accommodating groove 110, and the locking structure 300 can have the first state and the second state relative to the first shell 100.

[0117] For example, along the rotation axis of the roller 500, the accommodating groove 110 can be located in the interior of the first shell 100, so that the locking structure 300 located in the accommodating groove 110 does not protrude out of the first shell 100.

[0118] In addition, the first direction is arranged perpendicular to the rotation axis, so that the moving direction of the locking structure 300 is perpendicular to the rotation axis, thereby further reducing the possibility of the locking structure 300 protruding out of the first shell 100 in the direction of the rotation axis, and reducing the length of the cover plate assembly in the direction of the rotation axis.

[0119] The accommodating groove 110 can have a first inner wall and a second inner wall. The first inner wall can be arranged as an inner wall of the accommodating groove 110 close to the second shell 400. The number of the second inner walls can be two, and the two second inner walls can be arranged as two inner walls of the accommodating groove 100 extending in the first direction and oppositely arranged. The two second inner walls can be connected with the first inner wall.

[0120] For example, the locking structure 300 has a fixed end and a movable end in the first direction, so that the locking structure 300 is driven to move in the first direction in the accommodating groove 110 by the fixed end of the locking structure 300. The fixed end is close to the rotation axis, and the movable end is away from the rotation axis.

[0121] The fixed end of the locking structure 300 can be provided with a pressing portion 340, so that the locking structure 300 is driven to move in the first direction in the accommodating groove 110 by the pressing portion 340, thereby making the movement process of the locking structure 300 more convenient.

[0122] Alternatively, the pressing portion 340 can be arranged at the movable end of the locking structure 300, and the locking structure 300 is driven to move in the first direction in the accommodating groove 110 by the movable end of the locking structure 300.

[0123] In the first direction, the accommodating groove 110 can have oppositely arranged first and second through openings. The first through opening is arranged close to the rotation axis, and the second through opening is away from the rotation axis. The locking structure 300 is arranged in the accommodating groove 110, the fixed end of the locking structure 300 is close to the first through opening, and the movable end of the locking structure 300 is close to the second through opening.

[0124] During the process in which the locking structure 300 slides in the first direction in the accommodation groove 110, the active end does not protrude from the first housing portion 100, i.e., the active end does not protrude from the second through-hole, so that the overall volume of the cover plate assembly does not increase due to the movement of the locking structure 300, thereby being able to reduce the influence of the locking structure 300 on the volume of the cover plate assembly.

[0125] That is, during the process in which the locking structure 300 slides in the first direction in the accommodation groove 110, the locking structure 300 is located inside the first housing portion 100 in a plane perpendicular to the rotation axis, thereby being able to reduce the possibility that the locking structure 300 increases the overall volume of the cover plate assembly.

[0126] Alternatively, during the process in which the locking structure 300 slides in the first direction in the accommodation groove 110, when the locking structure 300 is in the first position, the active end is arranged flush with the outer peripheral curved surface of the first housing portion 100, and the active end does not protrude from the first housing portion 100, thereby being able to reduce the possibility that the locking structure 300 increases the overall volume of the cover plate assembly.

[0127] When the locking structure 300 is in the second position, the active end protrudes from the first housing portion 100, so that the remaining part of the locking structure is located in the accommodation groove 110, thereby reducing the possibility that the locking structure 300 is separated from the accommodation groove 110.

[0128] In some possible embodiments, the locking structure 300 can include the communication portion 320 and the blocking portion 310 arranged at intervals in the first direction, thereby being able to realize different states of the locking structure 300 through the communication portion 320 and the blocking portion 310.

[0129] Referring to Figure 5 and Figure 6 , for example, when the locking structure 300 is in the first state, the locking structure 300 can be in the first position, and the locking structure 300 can fix the cover plate 200 through the blocking portion 310, so that the cover plate 200 can be relatively fixed with the housing 10.

[0130] For example, when the locking structure 300 is in the first position, the blocking portion 310 can be located on the rotation path of the cover plate 200, and the blocking portion 310 can be in contact with the cover plate 200, thereby being able to limit the rotation of the cover plate 200 through the blocking portion 310.

[0131] Referring to Figure 7 and Figure 8 , when the locking structure 300 is in the second state, the locking structure 300 is in the second position, and the cover plate 200 can rotate relative to the housing 10 through the communication portion 320, so that the cover plate 200 rotates between the front side of the drum 500 in the advancing direction and the lower side of the drum 500, and the cover plate 200 can be fixed at the front side of the drum in the advancing direction and the lower side of the drum 500 through the locking structure 300.

[0132] When the position of the cover plate 200 needs to be adjusted, the locking structure 300 can be slid in the first direction in the accommodating groove 110, so that the locking structure 300 is in the second position, the locking structure 300 can correspond to the cover plate 200 through the communication part 320, the cover plate 200 can be rotated relative to the shell 10 through the communication part 320, so that the cover plate 200 can be detached from the shell 10.

[0133] Then, the locking structure 300 can be slid in the first direction in the accommodating groove 110, so that the locking structure 300 is in the first position, the locking structure 300 fixes the cover plate 200 through the blocking part 310, so that the cover plate 200 can be fixed with the shell 10, to realize the adjustment of the position of the cover plate 200.

[0134] For example, the first shell part 100 can be provided with a rotating cavity 130. At least part of the cover plate 200 can be arranged in the rotating cavity 130 around the rotating axis, so that the cover plate 200 can be rotated relative to the first shell part 100 in the rotating cavity 130.

[0135] When the locking structure 300 is in the first position, the blocking part 310 can axially extend into the rotating cavity 130, so that the blocking part 310 can be located on the rotating path of the cover plate 200.

[0136] When the locking structure 300 is in the second position, the communication part 320 extends into the rotating cavity 130, so that the communication part 320 can be located on the rotating path of the cover plate 200, so that the cover plate 200 can be rotated relative to the shell 10, to realize the dismounting process of the cover plate 200.

[0137] When the locking structure 300 is in the first position, the blocking part 310 extends into the rotating cavity 130, so that the blocking part 310 can be used to abut against the cover plate 200, so that the rotation of the cover plate 200 in the rotating cavity 130 can be limited by the blocking part 310, so that the cover plate 200 can be relatively fixed with the shell 10.

[0138] When the locking structure 300 is in the second position, the communication part 320 extends into the rotating cavity 130, so that the communication part 320 can be arranged opposite to the cover plate 200, and the communication part 320 will not interfere with the rotation process of the cover plate 200 in the rotating cavity 130, so that the cover plate 200 can be rotated around the rotating axis in the rotating cavity 130 through the communication part 320 of the locking structure 300.

[0139] For example, with reference to Figure 9 and Figure 10The cover plate 200 can be provided with a limiting piece 220. The limiting piece 220 can be rotatably arranged in the rotating cavity 130 about the rotating axis. The communicating part 320 can include a communicating opening 321, and the communicating opening 321 can be used for the limiting piece 220 to pass through when the locking structure 300 is in the second position.

[0140] When the locking structure 300 is in the first position, the blocking part 310 extends into the rotating cavity 130, and the blocking part 310 can be opposite to the limiting piece 220 located in the rotating cavity 130, so that the blocking part 310 can play a certain blocking role on the rotating process of the limiting piece 220, so that the cover plate 200 and the shell 10 are relatively fixed.

[0141] When the locking structure 300 is in the second position, the communicating part 320 extends into the rotating cavity 130, so that the communicating part 320 can be arranged opposite to the cover plate 200, and the communicating opening 321 of the communicating part 320 is communicated with the rotating cavity 130.

[0142] When the limiting piece 220 of the cover plate 200 rotates in the rotating cavity 130 about the rotating axis, the limiting piece 220 of the cover plate 200 can rotate through the communicating opening 321, so that the communicating opening 321 will not block the rotating process of the limiting piece 220.

[0143] For example, referring to Figure 9 and Figure 10 , the first shell part 100 can be provided with a movable opening 120 facing downward, and the movable opening 120 is communicated with the rotating cavity 130. The limiting piece 220 can enter the rotating cavity 130 through the movable opening 120 and move out of the rotating cavity 130 through the movable opening 120.

[0144] When the locking structure 300 is in the second position, the cover plate 200 can rotate between the front side of the roller 500 along the advancing direction and the lower side of the roller 500. By providing the first shell part 100 with the movable opening 120 facing downward, the limiting piece 220 can enter the rotating cavity 130 through the movable opening 120 and move out of the rotating cavity 130 through the movable opening 120, so as to ensure the stability of the rotating process of the cover plate 200.

[0145] For example, referring to Figures 5-8 , in some possible embodiments, one of the second inner wall of the accommodating groove 110 and the locking structure 300 can be provided with an adjusting part 330.

[0146] For example, the other one of the second inner wall of the accommodating groove 110 and the locking structure 300 can be provided with a first fixing part 112 and a second fixing part 113, and the first fixing part 112 and the second fixing part 113 are arranged in the first direction. The adjusting part 330 can be used in cooperation with the first fixing part 112 and the second fixing part 113.

[0147] When the locking structure 300 is in the first position, the adjusting portion 330 is connected with the first fixing portion 112, and the locking structure 300 can be relatively fixed with the first shell portion 100. When the locking structure 300 is in the second position, the adjusting portion 330 is connected with the second fixing portion 113, and the locking structure 300 can be relatively fixed with the first shell portion 100.

[0148] For example, the adjusting portion 330 can be an adjusting protrusion, the first fixing portion 112 can be a first groove, and the second fixing portion 113 can be a second groove.

[0149] When the locking structure 300 is in the first position, the adjusting protrusion is inserted into the first groove, so that the locking structure 300 can be relatively fixed with the first shell portion 100. When the locking structure 300 is in the second position, the adjusting protrusion is inserted into the second groove, so that the locking structure 300 can be relatively fixed with the first shell portion 100.

[0150] Referring to Figure 9 and Figure 10 In some possible embodiments, the cover plate 200 can include a locking portion 210 to be fixed with the locking structure 300 through the locking portion 210.

[0151] For example, when the locking structure 300 is in the first state, the cover plate 200 can be towards the front side of the shell 10, and the cover plate 200 can be fixed with the locking structure 300 through the locking portion 210. The locking portion 210 can be a locking groove, which can be used to accommodate the blocking portion 310.

[0152] When the locking structure 300 is in the first state, the cover plate 200 can be fixed with the locking structure 300 through the locking portion 210, and the cover plate 200 is towards the front side of the shell 10, so that the connection between the cover plate 200 and the locking structure 300 can be more stable through the locking portion 210 arranged on the cover plate 200.

[0153] In some possible embodiments, the locking portion 210 can be a clamping groove. When the cover plate 200 is towards the front side of the shell 10, the clamping groove is clamped with at least part of the cover plate 200, so that the locking structure 300 can be fixed with the clamping groove of the cover plate 200.

[0154] In summary, in the cover plate assembly, the locking structure 300 has relatively first and second states. When the locking structure 300 is in the first state, the locking structure 300 can fix the cover plate 200, so that the cover plate 200 is relatively fixed with the shell 10 to realize the installation process of the cover plate 200. The shell 10 can drive the cover plate 200 to rotate relative to the roller 500, and the cover plate 200 located below the roller 500 can reduce the possibility of the roller 500 polluting the carpet.

[0155] When the locking structure 300 is in the second state, the locking structure 300 can release the cover plate 200, so that the cover plate 200 can rotate relative to the shell 10 about the rotation axis, and the cover plate 200 can be detached from the shell 10.

[0156] Compared with the related art, the cover plate assembly in the embodiment of the present application can realize the connection and separation of the cover plate and the shell by adjusting the state of the locking structure, so that the cover plate can be more conveniently detached without the need to provide fasteners or other connecting structures on the cover plate and the shell.

[0157] In addition, in the related art, the locking structure is located on the side of the drum away from the obstacle, and when the side of the locking structure is close to the obstacle (for example, a wall), the locking structure will first contact the wall, so that a larger gap is formed between the end of the drum close to the locking structure and the wall, and the drum has difficulty in cleaning the gap between the locking structure and the wall, which causes a cleaning blind area between the drum and the locking structure that is difficult for the drum to clean.

[0158] In the embodiment of the present application, the locking structure 300 is arranged on the first shell part 100, and when the end of the drum 500 away from the locking structure 300 is close to the obstacle, the locking structure 300 is located on the side of the drum 500 away from the obstacle, so that the locking structure 300 does not increase the distance between the drum and the obstacle, thereby reducing the area of the cleaning blind area between the locking structure and the drum and improving the cleaning effect of the robot.

[0159] The embodiment of the present application also provides a cleaning member, which comprises a drum and the cover plate assembly of any of the above embodiments.

[0160] The drum is rotatably arranged on the first shell part 100 about the rotation axis at one end in the axial direction, and rotatably arranged on the second shell part 400 about the rotation axis at the other end in the axial direction.

[0161] Since the cleaning member comprises the cover plate assembly of any of the above embodiments, the cleaning member has the advantages of the cover plate assembly of any of the above embodiments, and specific details can be referred to the above description, which will not be repeated here.

[0162] The embodiment of the present application also provides a robot, which comprises the cleaning member.

[0163] Since the robot comprises the cleaning member, the robot has the advantages of the cleaning member, and specific details can be referred to the above description, which will not be repeated here.
