[0023] In one embodiment, the reset member is an elastic member.

[0024] In one embodiment, the cleaning member is capable of moving in an up and down direction relative to the body assembly.

When the cleaning device is in the edge mode, it is necessary to clean the corner position close to the target edge, and the first driving device drives the transmission device to drive the cleaning member to rotate.

[0046] It should be noted that, in the absence of conflict, the embodiments and technical features in the embodiments of the present application can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of the present application and should not be regarded as an improper limitation on the present application.

[0047] In the description of the embodiments of the present application, "up", "down", "top", "bottom", orientation or position relationship is based on the orientation or position relationship shown in the accompanying drawings. It should be understood that these orientation terms are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0048] In the related art, the corresponding driving mechanism drives the cleaning member to rotate around the fixed axis so that the cleaning member cleans the floor, that is, the rotation centerline of the cleaning member cannot move. When the cleaning device moves along the edge (for example, along the wall) to clean the floor, the body component is spaced a certain distance from the target edge (for example, the wall, the edge of furniture). Since the rotation centerline of the cleaning member cannot move, the cleaning member may be spaced a certain distance from the target edge, and it is difficult for the cleaning member to clean positions near corners. Therefore, there may be a cleaning blind spot, and it is difficult for the cleaning member to clean positions near corners of the cleaned object.

[0049] In view of this, the present application embodiment provides a cleaning device, please refer to Figure 1 to Figure 5The cleaning device includes a body assembly 1, a first driving device 2, a transmission device 3, a cleaning member 4 and a reset member 5. The first driving device 2 is installed on the body assembly 1. The transmission device 3 is connected to the first driving device 2. The cleaning member 4 is connected to the transmission device 3, and the cleaning member 4 is used to clean the surface to be cleaned. During the process of the first driving device 2 driving the cleaning member 4 to rotate through the transmission device 3, the force generated by the rotation of the cleaning member 4 drives the cleaning member 4 to move from the first position to the second position. The reset member 5 is connected to the cleaning member 4 and / or the transmission device 3, and the force generated by the reset member 5 drives the cleaning member 4 to move from the second position to the first position. With such a structural form, the cleaning member 4 of the present application is driven by the first driving device 2 and reset by the reset member 5, so that the cleaning member 4 can switch between the first position and the second position according to actual needs. When the cleaning device is in the edge mode, it is necessary to clean the corners close to the target edge 9. The first drive device 2 drives the transmission device 3 to drive the cleaning member 4 to rotate. The force generated by the rotation of the cleaning member 4 drives the cleaning member 4 to move from the first position to the second position, which is beneficial to cleaning the corners of the target edge 9 and reducing the cleaning blind spot, so that the cleaned object can be better cleaned as much as possible.

[0050] It should be noted that the force generated by the rotation of the cleaning member 4 is mainly the friction generated by the contact between the cleaning member 4 and the surface to be cleaned of the object to be cleaned during the rotation process. This friction force reacts on the cleaning member 4 to form a reaction torque opposite to the rotation direction of the cleaning member 4.

[0051] It should be explained that the cleaning member 4 is used to clean the surface to be cleaned, and the surface to be cleaned here is the surface to be cleaned of the object to be cleaned.

[0052] Exemplarily, the first drive device is partially connected to the fuselage component, so that the first drive device can be fixedly mounted on the fuselage component.

[0053] In one embodiment, please refer to Figure 3 to Figure 6 The transmission device 3 includes a transmission body 31 and an input shaft 32 and an output shaft 33 connected to the transmission body 31. In such a structural form, the transmission body 31 receives the power input of the first driving device 2 through the input shaft 32 to rotate the input shaft 32. During the rotation of the input shaft 32, the transmission body 31 transmits the rotational motion of the input shaft 32 to the output shaft 33, so that the output shaft 33 rotates relative to the transmission body 31, and then transmits the power to the cleaning member 4 through the output shaft 33 to rotate the cleaning member 4, thereby cleaning the surface to be cleaned.

[0054] It should be noted that both the input shaft 32 and the output shaft 33 are capable of rotating relative to at least a portion of the structure of the transmission body 31 .

[0055] It can be understood that the specific structure of the transmission device 3 is not limited, as long as it can transmit the power of the first driving device 2 to the cleaning member 4 to move the cleaning member 4 to clean the surface to be cleaned.

[0056] In one embodiment, please refer to Figure 3 to Figure 6 , the input shaft 32 is rotatably connected with the body assembly 1, the first driving device 2 is used to drive the input shaft 32 to rotate so that the output shaft 33 rotates accordingly, and the cleaning member 4 is connected to the output shaft 33 to rotate with the output shaft 33. In this structural form, the input shaft 32 is rotatably connected with the body assembly 1, and the input shaft 32 rotates relative to the body assembly 1, that is, the central axis of the input shaft 32 hardly moves relative to the body assembly 1. The input shaft 32 is driven to rotate by the first driving device 2 and the output shaft 33 is driven to rotate accordingly through the transmission body 31, thereby driving the cleaning member 4 connected to the output shaft 33 to rotate.

[0057] It is understandable that the connection relationship between the input shaft 32 and the output shaft 33 is not limited, as long as the input shaft 32 can be driven by the first driving device 2 to drive the output shaft 33 to rotate, and then the output shaft 33 can drive the cleaning member 4 to rotate.

[0058] In one embodiment, please refer to Figure 3 to Figure 5 , the transmission device 3 and the cleaning member 4 are integrally formed to be able to rotate around the input shaft 32. In this structural form, the cleaning member 4 rotates around the input shaft 32, and the cleaning member 4 has little influence on the position of the first driving device 2 during the process of moving from the first position to the second position.

[0059] It can be understood that, in the process that the force generated by the rotation of the cleaning member 4 drives the cleaning member 4 to move from the first position to the second position, the cleaning member 4, the output shaft 33 and the transmission body 31 rotate around the input shaft 32 as a whole. Since the input shaft 32 is rotatably connected to the fuselage assembly 1, the cleaning member 4, the output shaft 33 and the transmission body 31 rotate around the input shaft 32 as a whole. The corresponding mounting position of the first drive device 2 on the fuselage assembly 1 can basically remain unchanged, which is convenient for the installation of the first drive device 2. The wiring required for power supply, etc. connected to the first drive device 2 does not need to move with the first drive device 2, which is also convenient for the wiring required for power supply, etc. of the first drive device 2.

[0060] In one embodiment, please refer to Figure 3 to Figure 6 , the input shaft 32 and the output shaft 33 are arranged eccentrically.

[0061] In one embodiment, please refer to Figure 1 to Figure 5, the cleaning member 4 is used to clean the surface to be cleaned of the cleaned object, the transmission device 3 and the cleaning member 4 as a whole can rotate around the input shaft 32 to switch between the second position and the first position, the number of the cleaning member 4 is one or at least two, wherein the edge of the body component 1 along the preset direction facing the side corresponding to the cleaning member 4 is the preset edge 10, the preset direction is respectively perpendicular to the moving direction and the up and down direction of the body component 1, and the second position is located at the side of the first position along the preset direction facing the preset edge 10.

[0062] It should be noted that when the cleaning device needs to clean the corners near the target edge 9, the cleaning member 4 is switched from the first position to the second position under the action of the counter torque applied by the surface to be cleaned of the cleaned object, and the corresponding cleaning member 4 extends from the body component 1, and the cleaning member 4 extends more outside the outline of the body component 1. When the cleaning device does not need to clean the corners near the target edge 9, the cleaning member 4 can be retracted from the second position to the first position.

[0063] It should be noted that the second position is located on the side of the first position along the preset direction toward the corresponding preset edge 10, the cleaning member 4 located at the first position is closer to the middle position of the body assembly 1 in the preset direction, and the cleaning member 4 located at the second position can extend further out of the body assembly 1 along the preset direction.

[0064] Exemplarily, the transmission body 31 is a reduction box.

[0065] For example, see Figure 6 , the up and down directions are the directions indicated by arrow R1 in the figure.

[0066] For example, see Figure 1 and Figure 2 , the preset direction is the direction indicated by the arrow R2 in the figure.

[0067] For example, see Figure 1 and Figure 2 The moving direction of the fuselage assembly 1 is the direction indicated by the arrow R4 in the figure.

[0068] Exemplarily, when the cleaning member 4 is separated from the object to be cleaned, the cleaning member 4 is no longer affected by the counter torque of the object to be cleaned, and the cleaning member 4 can be switched from the second position back to the first position.

[0069] For example, see Figure 1 , as shown in the figure, both the left and right cleaning members 4 are located in the first position.

[0070] For example, see Figure 2, the left cleaning member 4 is shown in the first position, and the right cleaning member 4 is shown in the second position.

[0071] For example, see Figure 6 , the input shaft 32 is parallel to the output shaft 33.

[0072] It should be noted that the input shaft 32 and the output shaft 33 are eccentrically arranged, that is, the input shaft 32 and the output shaft 33 are spaced apart by a certain distance along the radial direction of the input shaft 32 .

[0073] Exemplarily, the object to be cleaned may be the ground, and the supporting surface of the object to be cleaned is the surface to be cleaned on the ground.

[0074] Exemplarily, the cleaning device is a mop.

[0075] Exemplarily, the cleaning member 4 is a mop tray provided with a rag.

[0076] Exemplarily, the cleaning member 4 may also be a side brush, a roller brush or other possible cleaning members.

[0077] In one embodiment, please refer to Figure 3 , the first driving device 2 is located on one side of the input shaft 32 along the radial direction of the input shaft 32. In this structural form, the first driving device 2 drives the input shaft 32 from one side of the radial direction of the input shaft 32, so that both ends of the input shaft 32 can be more conveniently connected to the fuselage assembly 1 to realize the fixed axis rotation of the input shaft 32.

[0078] It is understandable that the installation position of the first driving device is not limited. Exemplarily, the first driving device 2 is drivingly connected to one end of the input shaft 32 to drive the input shaft 32 to rotate.

[0079] In one embodiment, please refer to Figure 3The first driving device 2 includes a driver 21, a first transmission wheel 23, a second transmission wheel 24 and a worm 22. The driver 21 is installed on the body assembly 1. The first transmission wheel 23 is rotatably connected with the body assembly 1. The second transmission wheel 24 is sleeved on the input shaft 32 to rotate with the input shaft 32. The worm 22 is installed on the driver 21 so that the driver 21 drives the worm 22 to rotate. The worm 22 is meshed with the first transmission wheel 23, and the first transmission wheel 23 and the second transmission wheel 24 are meshed. In this structural form, the first transmission wheel 23 is rotatably connected with the body assembly 1, the first transmission wheel 23 rotates with a fixed axis, and the rotation center axis of the first transmission wheel 23 remains substantially unchanged relative to the body assembly 1. The driver 21 drives the worm 22 to rotate, so that the first transmission wheel 23 and the second transmission wheel 24 that are meshed in sequence rotate, and the rotating second transmission wheel 24 drives the input shaft 32 to rotate. The two ends of the input shaft 32 do not need to receive kinetic energy input, so that the input shaft 32 can be more conveniently connected to the body assembly 1 for rotation, and it is beneficial to reduce the axial size of the cleaning device along the input shaft 32.

[0080] Exemplarily, the driver 21 may be a motor.

[0081] Exemplarily, the first transmission wheel 23 and the second transmission wheel 24 are both helical gears.

[0082] For example, the input shaft 32 may be directly driven to rotate by the driver 21 .

[0083] For example, see Figure 1 , Figure 2 , Figure 4 and Figure 5 The rotation direction of the cleaning member 4 is the direction indicated by the arrow R3 in the figure.

[0084] For example, see Figure 4 and Figure 5 The reaction torque applied by the cleaned object to the cleaning member 4 is M, and the direction indicated by the arrow corresponding to the reaction torque M in the figure is the direction of the reaction torque M.

[0085] It can be understood that the number of the cleaning members 4 is not limited. For example, the number of the cleaning members 4 can be one or at least two.

[0086] For example, see Figure 1 and Figure 2 The number of the cleaning members may be at least two, and the at least two cleaning members may contact the cleaned object one by one so that the corresponding cleaning members switch between the second position and the first position.

[0087] For example, see Figure 1 and Figure 2The number of the cleaning members may be at least two, and among the at least two cleaning members, all the cleaning members are in contact with the ground together so that all the cleaning members are switched between the corresponding second position and the first position together.

[0088] In one embodiment, please refer to Figure 1 and Figure 2 , the projection area of ​​the cleaning member 4 along the up-down direction is the first area 41, the projection area of ​​the fuselage assembly 1 along the up-down direction is the second area 11, the limit boundaries of the second area 11 on the opposite sides along the preset direction are the target boundaries 12, when the cleaning member 4 is in the second position, the first area 41 is arranged along the preset direction on both sides corresponding to the target boundary 12, when the cleaning member 4 is in the first position, the first area 41 is located on the side of the target boundary 12 facing the second area 11, and the cleaning member 4 is below the fuselage assembly 1. In this structural form, the cleaning member 4 switches between the second position and the first position, the cleaning member 4 is in the second position, the first area 41 is arranged along the preset direction on both sides corresponding to the target boundary 12, when the cleaning member 4 cleans the corners at the position close to the target edge 9, the cleaning member 4 extends out of the fuselage assembly 1 close to the target edge 9, so that the cleaning member 4 can clean the object to be cleaned as far as possible. When the cleaning member 4 is in the first position, the first area 41 is located on the side of the target boundary 12 facing the second area 11 , and the cleaning member 4 is stored under the body assembly 1 , so as to clean the path along which the body assembly 1 passes.

[0089] It should be noted that the first area 41 is arranged along the preset direction on both sides of the corresponding target boundary 12 , that is, the first area 41 is at least partially offset from the second area 11 , and there is an area of ​​the first area 41 that does not overlap with the second area 11 .

[0090] It can be understood that the boundary of the second area 11 along the preset direction generally does not exceed the target boundary 12 .

[0091] It can be understood that when the cleaning member 4 is in the first position, the arrangement of the first area 41 and the second area 11 of the embodiment of the present application is not limited. Exemplarily, when the cleaning member 4 is in the first position, the first area 41 can be arranged along the preset direction across the two sides corresponding to the target boundary 12, and the cleaning member 4 can be partially exposed laterally outside the fuselage component 1. When the cleaning member 4 is in the second position, the first area 41 corresponding to the cleaning member 4 further protrudes toward the side of the target boundary 12 away from the second area 11, and the cleaning member 4 is more laterally exposed to the fuselage component 1, and the projection area of ​​the part of the cleaning member 4 exposed laterally to the fuselage component 1 along the up-down direction is larger.

[0092] For example, see Figure 1, the cleaning member 4 is disengaged from the second position and reset to the first position, and the cleaning device is in a mode where the cleaning member 4 normally cleans the object to be cleaned. For example, when the cleaning device is generally cleaning an open ground and the body assembly 1 of the cleaning device is far from the target edge 9, the cleaning member 4 can be disengaged from the second position and reset to the first position according to actual needs, and the cleaning device is no longer in the edge cleaning mode.

[0093] For example, see Figure 2 , the right cleaning member 4 is shown in the second position, the first area 41 is arranged along the preset direction across the two sides corresponding to the target boundary 12, and the cleaning device is in the edge cleaning mode in which the cleaning member 4 cleans the corners at the position close to the target edge 9.

[0094] It should be noted that the outer side of the target boundary 12 is the side of the target boundary 12 away from the second area 11 .

[0095] In one embodiment, please refer to Figure 1 and Figure 2 When the cleaning member 4 is at the first position, the projection area of ​​the edge of the cleaning member 4 outside the edge projection area of ​​the fuselage component 1 is smaller than the area of ​​the edge of the cleaning member 4 outside the edge projection area of ​​the fuselage component 1 when the cleaning member 4 is at the second position. With such a structural form, the cleaning member 4 at the second position can be more exposed to the edge of the fuselage component 1 than the cleaning member 4 at the first position, and the cleaning member 4 at the second position can better clean the corner position of the target edge 9.

[0096] It is understandable that the projection area of ​​the cleaning member 4 in the second position along the vertical direction and the projection area of ​​the cleaning member 4 in the first position along the vertical direction can both be located within the projection area of ​​the body assembly 1 in the vertical direction, as long as the cleaning member 4 in the second position is closer to the edge of the body assembly 1 than the cleaning member 4 in the first position.

[0097] It can be understood that the projection area of ​​the cleaning member 4 at the second position along the up-down direction and the projection area of ​​the cleaning member 4 at the first position along the up-down direction may both be partially located outside the projection area of ​​the body assembly 1 along the up-down direction.

[0098] In one embodiment, please refer to Figure 3 and Figure 4 The body assembly 1 has a second limiting portion 13. When the cleaning member 4 is located at the second position, the second limiting portion 13 and the transmission device 3 are in limiting contact with each other to prevent the cleaning member 4 from moving due to the force generated by the rotation. In this structural form, the second limiting portion 13 is in contact with the transmission device 3, so that the cleaning member 4 is kept in the second position as much as possible, which can prevent the cleaning member 4 from moving too far outward under the action of the counter torque of the cleaned object to a certain extent.

[0099] Exemplarily, the second limiting portion 13 abuts against the transmission body 31 for limiting position.

[0100] Exemplarily, the second limiting portion 13 abuts against the output shaft 33 for limiting.

[0101] It is understandable that the embodiment of the present application is not limited to limiting the transmission device 3 by the second limiting portion 13. For example, the transmission device 3 can be limited by the housing of the first driving device 2.

[0102] In one embodiment, please refer to Figure 3 to Figure 5 The reset member 5 is an elastic member. In this structural form, the cleaning member 4 is reset by the elastic force of the elastic member.

[0103] It is understandable that the specific structural form of the reset member 5 is not limited. Exemplarily, the reset member 5 can be a structure with active reset power.

[0104] In one embodiment, please refer to Figure 3 to Figure 5 , the cleaning member 4 can move in the up-down direction relative to the body assembly 1. When the cleaning member 4 contacts the object to be cleaned, the force generated by the rotation of the cleaning member 4 drives the cleaning member 4 to overcome the elastic force of the elastic member and move from the first position to the second position. When the cleaning member 4 is out of contact with the object to be cleaned, the cleaning member 4 in an upwardly lifted state relative to the body assembly 1 can move from the second position to the first position under the elastic force of the elastic member. With such a structural form, the cleaning member 4 can be brought into contact with or out of contact with the object to be cleaned by lifting and lowering the cleaning member 4 in the up-down direction relative to the body assembly 1. The cleaning member 4 in contact with the object to be cleaned overcomes the elastic force of the elastic member and moves to the second position under the action of the counter torque applied by the surface to be cleaned of the object to be cleaned, so that the cleaning member 4 can better clean the corners at a position close to the target edge 9. When the corners near the target edge 9 are cleaned, the cleaning member 4 can be lifted upward relative to the body assembly 1 to separate from the object to be cleaned. The object to be cleaned no longer applies a reaction torque to the cleaning member 4, and the transmission device 3 is reset from the second position to the first position under the action of the elastic force of the elastic member.

[0105] For example, see Figure 3 to Figure 5 The reset member 5 is connected to the fuselage assembly 1 and the transmission device 3 respectively.

[0106] Exemplarily, the restoring member 5 is connected to the body component 1 and the cleaning member 4 respectively.

[0107] For example, see Figure 3 to Figure 5The force generated by the rotation of the cleaning member 4 drives the cleaning member 4 to overcome the elastic force of the elastic member and rotate around the input shaft 32 to move the cleaning member 4 to the second position. For example, the reset member 5 can be a spring, an elastic rope, other elastic materials or elastic structures, etc., which are not specifically limited here.

[0108] Exemplarily, the output shaft 33 is a telescopic shaft, and the output shaft 33 is extended and retracted to drive the cleaning member 4 to move in the up-down direction relative to the body assembly 1. For example, when the cleaning member 4 is needed for cleaning, the output shaft 33 is extended, stretched and locked, so that the cleaning member 4 disposed on the output shaft 33 is in contact with the object to be cleaned. After cleaning is completed, the output shaft 33 can be retracted and locked, so that the cleaning member 4 disposed on the output shaft 33 is separated from the object to be cleaned.

[0109] Exemplarily, the output shaft 33 includes a main shaft and a telescopic rod, the telescopic rod is coaxially arranged with the main shaft, one end of the telescopic rod is connected to the main shaft to rotate with the main shaft, and the other end of the telescopic end is connected to the cleaning piece. The main shaft rotates under the action of the input shaft and the transmission body, thereby driving the telescopic rod and the cleaning piece to rotate, and the cleaning piece is driven to rise and fall by the telescopic rod extending and retracting.

[0110] Exemplarily, the first driving device 2, the transmission device 3 and the cleaning member 4 can be driven by the body assembly 1 to move up and down as a whole, so as to drive the cleaning member 4 to move relative to the body in the up and down direction.

[0111] It is understandable that the second limiting portion 13 may not be provided, and the cleaning member 4 is substantially maintained near the second position by balancing the reaction torque applied by the cleaning member 4 and the elastic force of the reset member 5 .

[0112] Exemplarily, the reset member 5 is connected to the body assembly 1 and the transmission body 31 respectively, and the transmission body 31 is pulled to move by the pulling force of the reset member 5, so that the cleaning member 4 is released from the second position and reset.

[0113] For example, see Figure 3 to Figure 5 One end of the reset member 5 is connected to the body assembly 1, and the other end of the reset member 5 is connected to the transmission body 31. The position where the reset member 5 is connected to the transmission body 31 is located on the side of the input shaft 32 away from the output shaft 33. When the cleaning member 4 is located at the first position, the center line of the input shaft 32 and the output shaft 33 and the direction of the elastic force of the reset member 5 are arranged crosswise.

[0114] In one embodiment, please refer to Figure 5The body assembly 1 has a first position-limiting portion 14. When the cleaning member 4 is located at the first position, the first position-limiting portion 14 can abut against the transmission device 3 to prevent the transmission device 3 from moving under the action of the reset member 5. In this structural form, when the first position-limiting portion 14 abuts against the transmission device 3, the first position-limiting portion 14 prevents the transmission device 3 from moving under the action of the reset member 5, and the transmission device 3 is reset to the limit position abutting against the first position-limiting portion 14 under the action of the reset member 5.

[0115] Exemplarily, when the cleaning member 4 is located at the first position, the first limiting portion 14 abuts against the transmission device 3 to limit the position.

[0116] Exemplarily, the body assembly 1 has a second limiting portion 13 and a first limiting portion 14, the transmission device 3 abuts against the second limiting portion 13 to limit the cleaning member 4 to the second position, and the transmission device 3 abuts against the first limiting portion 14 to limit the cleaning member 4 to the first position.

[0117] Exemplarily, the first limiting portion 14 abuts against the transmission body 31 for limiting position.

[0118] Exemplarily, the first limiting portion 14 abuts against the output shaft 33 for limiting position.

[0119] In one embodiment, please refer to Figure 3 to Figure 5 The body assembly 1 has an installation cavity 15 and an avoidance groove 16 that are interconnected. The first drive device 2 and the transmission body 31 are located in the installation cavity 15. The output shaft 33 passes through the avoidance groove 16. The output shaft 33 partially extends to the outside of the installation cavity 15. The cleaning member 4 is located outside the installation cavity 15. In such a structural form, the first drive device 2 and the transmission body 31 are located in the installation cavity 15 of the body assembly 1, which can reduce the possibility of the first drive device 2 and the transmission body 31 being exposed. The body assembly 1 can better protect the first drive device 2 and the transmission body 31 in the installation cavity 15, and reduce the possibility of the first drive device 2 and the transmission body 31 being damaged by external collisions and other factors. The output shaft 33 partially extends outside the installation cavity 15, which is convenient for driving the cleaning member 4 outside the installation cavity 15 to rotate, thereby cleaning the object to be cleaned.

[0120] For example, see Figure 3 to Figure 5 , the avoidance groove 16 is waist-shaped.

[0121] For example, see Figure 3 to Figure 5 The second limiting portion 13 is located at one end of the avoidance groove 16 , the first limiting portion 14 is located at the other end of the avoidance groove 16 , and the groove wall of the avoidance groove 16 spans the second limiting portion 13 and the first limiting portion 14 .

[0122] It is understandable that the fuselage assembly 1 may not be provided with the installation cavity 15 and the avoidance groove 16. Exemplarily, the first drive device 2 and the transmission body 31 may be arranged below the fuselage assembly 1 as appropriate, and the first drive device 2 and the transmission body 31 are downwardly located outside the fuselage assembly 1.

[0123] For example, see Figure 3 to Figure 6 The fuselage assembly 1 includes a fuselage body 18 and a drive shell 19, a mounting cavity 15 and an avoidance groove 16 are formed in the fuselage body 18, the drive shell 19 is located in the mounting cavity 15, the drive shell 19 is connected to the fuselage body 18, the transmission body 31 is located in the drive shell 19, the input shaft 32 of the transmission device 3 is rotatably connected to the drive shell 19, the input shaft 32 rotates relative to the drive shell 19, and correspondingly the input shaft 32 rotates relative to the fuselage body 18.

[0124] Exemplarily, the fuselage assembly 1 also includes a lifting cylinder installed on the fuselage body 18, which drives the corresponding drive shell 19 to rise and fall. The transmission body 31 in the drive shell 19 follows the rise and fall of the drive shell 19 to drive the corresponding output shaft 33 and the cleaning part 4 on the output shaft 33 to rise and fall together.

[0125] In one embodiment, please refer to Figure 3 to Figure 5 , Figure 7 and Figure 8 A locking platform 311 is formed on the transmission body 31 .

[0126] In one embodiment, please refer to Figure 3 to Figure 5 , Figure 7 and Figure 8 The cleaning device further comprises a locking mechanism 6, which is disposed on the body assembly 1 and is used to lock or unlock the cleaning member 4 located at the first position. When the locking mechanism 6 is unlocked, the force generated by the rotation of the cleaning member 4 drives the cleaning member 4 to move from the first position to the second position.

[0127] In the embodiment of the present application, when the cleaning device is in a non-edge-walking cleaning mode, the cleaning member 4 is locked in the first position by the locking mechanism 6, which is beneficial for better cleaning of the cleaned object on the path of the cleaning device.

[0128] It should be noted that the locking mechanism 6 is used to lock or unlock the cleaning member 4 located at the first position. The locking mechanism 6 can directly lock or unlock the cleaning member 4, or the locking mechanism 6 can also lock or unlock the transmission device 3 corresponding to the cleaning member 4 located at the first position.

[0129] Exemplarily, the force generated by the rotation of the cleaning member 4 drives the cleaning member 4 to rotate around the input shaft 32 to the first position.

[0130] For example, the cleaning element 4 is locked in the first position by the locking mechanism 6 .

[0131] In one embodiment, please refer to Figure 3 to Figure 5 , Figure 7 and Figure 8 The locking mechanism 6 can be locked with the locking platform 311 to prevent the cleaning member 4 from moving to the second position, and the locking mechanism 6 can unlock the locking platform 311 to allow the cleaning member 4 to move to the second position. In such a structural form, through the locking cooperation between the locking mechanism 6 and the locking platform 311, the output shaft 33 and the transmission body 31 can hardly rotate relative to the input shaft 32. When the cleaning member 4 cleans the object to be cleaned normally, the locking cooperation between the locking mechanism 6 and the locking platform 311 can prevent the cleaning member 4 from moving to the second position under the action of the counter torque applied by the object to be cleaned, thereby reducing the possibility that the cleaning member 4 malfunctions under the action of the counter torque applied by the object to be cleaned and moves to the second position. When the cleaning member 4 needs to be moved to the second position to clean the corners close to the target edge 9 when the fuselage main body 18 is close to the target edge 9, the locking platform 311 can be unlocked by the locking mechanism 6, and the rotation of the output shaft 33 and the transmission body 31 relative to the input shaft 32 is no longer restricted. The cleaning member 4 arranged on the output shaft 33 can rotate around the input shaft 32, thereby moving to the second position.

[0132] It should be explained that, here, the cleaning member 4 cleans the cleaned object normally, which means that the cleaning member 4 cleans the cleaned object in a relatively open place when it is reset after leaving the second position, and the main body 18 is not close to the target edge 9 .

[0133] In one embodiment, please refer to Figure 7 and Figure 8A locking platform 311 is formed on the transmission device 3, a support portion 17 is formed on the fuselage assembly 1, and the locking mechanism 6 includes a locking pin 61 and a locking elastic member 62. The locking pin 61 is movably arranged on the fuselage assembly 1. The locking elastic member 62 is located between the locking pin 61 and the support portion 17, and the locking elastic member 62 contacts the locking pin 61 and the support portion 17 respectively. The locking pin 61 can extend to the locking position under the elastic force of the locking elastic member 62, and the locking platform 311 can abut against the locking pin 61 located at the locking position to lock the cleaning member 4. In such a structural form, the locking elastic member 62 is supported by the support portion 17, and the locking elastic member 62 applies elastic force to the locking pin 61, so that the locking pin 61 can be extended to the locking position, and the locking pin 61 is abutted against the locking platform 311 at the locking position. The locking platform 311 is blocked by the locking pin 61 and cannot move to the second position, thereby locking the cleaning member 4. The extended locking pin 61 and the locking platform 311 are abutted against the limiting position to keep the cleaning member 4 in a state of being disengaged from the second position and reset, so that the cleaning member 4 can clean the cleaned object normally. When the locking pin 61 overcomes the elastic force of the locking elastic member 62 and shrinks, the locking pin 61 releases the locking platform 311, and the cleaning member 4 moves to the second position to drive the output shaft 33 and the transmission body 31 to rotate around the input shaft 32. The cleaning member 4 can clean the cleaned object near the target edge 9 when the fuselage assembly 1 is close to the target edge 9.

[0134] For example, see Figure 5 When the cleaning member 4 is located at the first position, the transmission body 31 partially abuts between the locking pin 61 and the first limiting portion 14. The first limiting portion 14 and the locking pin 61 constrain the transmission body 31, so that the cleaning member 4 is maintained in the first position.

[0135] Exemplarily, the locking elastic member 62 may be a spring.

[0136] Exemplarily, the locking platform is formed on the transmission body 31 .

[0137] It is understandable that the body assembly 1 may not be provided with the first limiting portion 14. For example, when the cleaning member 4 contacts the object to be cleaned, the cleaning member 4 is kept in a reset state disengaged from the second position through the reaction torque applied by the object to be cleaned to the cleaning member 4 and the limiting of the locking pot by the locking pin 61, so that the cleaning member 4 can clean the object to be cleaned normally.

[0138] In one embodiment, please refer to Figure 7 and Figure 8, the locking pin 61 has an actuating portion 611, and the cleaning device further comprises a second driving device and a cam 8. The second driving device is mounted on the body assembly 1. The cam 8 is mounted on the second driving device, and the cam 8 and the locking elastic member 62 are respectively located on opposite sides of the actuating portion 611. The second driving device drives the cam 8 to rotate and drives the actuating portion 611 to move, so that the locking pin 61 overcomes the elastic force of the locking elastic member 62 and retracts from the locking position to the position of releasing the locking platform 311. In such a structural form, the cam 8 is driven to rotate by the second driving device, and when the part with a larger radius of the cam 8 gradually abuts against the actuating portion 611, the rotating cam 8 pushes the actuating portion 611 of the locking pin 61 to overcome the elastic force of the locking elastic member 62 and moves to drive the entire locking pin 61 to release the locking platform 311. The cam 8 is driven to rotate by the second driving device. When the portion with a smaller radius of the cam 8 gradually abuts against the actuating portion 611, the actuating portion 611 extends under the elastic force of the locking elastic member 62, so that the entire locking pin 61 extends to a locking position abutting against the locking platform 311. The cam 8 is driven to rotate by the second driving device, so that the locking pin 61 can automatically lock or unlock the locking platform 311.

[0139] Exemplarily, the second driving device may be a motor.

[0140] It is understandable that the embodiment of the present application is not limited to driving the cam 8 to rotate by the second driving device so that the lock pin 61 locks or unlocks the lock platform 311. For example, the operator can manually pull the lock pin 61 to switch.

[0141] It is understandable that the specific structure of the locking mechanism 6 of the embodiment of the present application is not limited. For example, the transmission body 31 can be limited by a baffle or a block so that the cleaning member 4 is kept in a reset state away from the second position.

[0142] In one embodiment, please refer to the figure, the end of the input shaft 32 that is away from the cleaning member 4 along the axial direction of the input shaft 32 is rotatably connected to the body component 1. With such a structural form, in the process of the cleaning member 4 contacting with the object to be cleaned to clean the object to be cleaned, since the end of the input shaft 32 that is away from the cleaning member 4 is rotatably connected to the body component 1, the force exerted by the object to be cleaned on the cleaning member 4 along the axial direction of the input shaft 32 can be balanced as much as possible by the force exerted by the body component 1 on the end of the input shaft 32 that is away from the cleaning member 4, thereby suppressing the cleaning member 4 from lifting up relative to the body component 1, so that there is a greater friction between the cleaning member 4 and the object to be cleaned, which is conducive to the cleaning member 4 to better clean the object to be cleaned.

[0143] It can be understood that the position of the input shaft 32 rotationally connected is not limited. Exemplarily, both ends of the input shaft 32 penetrate the transmission body 31, one end of the input shaft 32 along the axial direction of the input shaft 32 facing the cleaning member 4 is rotationally connected to the fuselage assembly 1, and one end of the input shaft 32 along the axial direction of the input shaft 32 away from the cleaning member 4 is spaced from the fuselage assembly 1. Exemplarily, both ends of the input shaft 32 penetrate the transmission body 31, and both ends of the input shaft 32 can be rotationally connected to the fuselage assembly 1.

[0144] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
