[0001] The utility model relates to the technical field of household appliances for sweeping floors, and in particular to a mopping device and a sweeping robot. Background Art

[0002] Sweeping robots have entered thousands of households and become a helpful assistant for people to clean. Many existing sweeping robots have cleaning mops that are fixed at the bottom of the machine body and do not have a stretching function, so they cannot clean the sanitary dead corners formed between the wall and the floor.

[0003] In order to overcome the above-mentioned defects, a Chinese utility model patent with announcement number CN207940856U discloses a sweeping robot, including a main body and a horizontally arranged cleaning device, wherein the cleaning device is arranged at the bottom of the main body, the cleaning device is movably connected to the main body, one end of the cleaning device extends beyond the outer edge of one side of the main body, and an elastic member for laterally resetting the cleaning device is also provided at the bottom of the main body. The cleaning device is arranged toward one side of the sweeping robot and can be automatically retracted and extended axially, thereby ensuring that there are no blind spots when the sweeping robot cleans the edge of the wall, and having a better cleaning effect.

[0004] Although the sweeping robot in the above patent solves the problem of cleaning blind spots, its elastic member always provides an outward force to the cleaning device to maintain and restore the protruding body of the cleaning device. Therefore, in any case, one end of the cleaning device protrudes from the body, affecting the appearance. When the sweeping robot returns to its original position, a larger ground area is required, and a special position needs to be reserved for the protruding end of the cleaning device. In some places or situations, users do not need to clean blind spots. At this time, the protruding end of the cleaning device is easily hit by objects and becomes a walking obstacle.

[0047] like Figure 1-4 and Figure 11-12 As shown, a mop device provided by an embodiment of the utility model comprises a housing 1 having a mop mounting groove 11 , a mop assembly 2 gap-fitted in the mop mounting groove 11 , and a driving mechanism 3 connected between the housing 1 and the mop assembly 2 .

[0048] The mop assembly 2 includes a main structure 21 and a cleaning mop 22 connected to the main structure 21 . The driving mechanism 3 is in transmission connection with the main structure 21 and can drive the main structure 21 to translate along the length direction of the mop installation slot 11 .

[0049] The mop assembly 2 has a first cleaning state and a second cleaning state.

[0050] When the mop assembly 2 is in the first cleaning state, the cleaning mop 22 is in the mop installation slot 11 .

[0051] When the mop assembly 2 is in the second cleaning state, one end of the cleaning mop 22 extends out of the outside of the mop installation slot 11 .

[0052] The mopping device provided by the utility model is used in a sweeping robot and is a component of the sweeping robot.

[0053] The mopping device provided by the utility model comprises a housing 1 , a mopping assembly 2 and a driving mechanism 3 .

[0054] The housing 1 may be integrated with the housing / body of the sweeping robot, or may be independent of the housing / body of the sweeping robot.

[0055] The bottom of the housing 1 is provided with a mop installation groove 11, and the length direction of the mop installation groove 11 is the width direction of the sweeping robot. If the forward direction of the sweeping robot is defined as the longitudinal direction, the width direction of the sweeping robot is the transverse direction. At least one end of the mop installation groove 11 is designed to be open, and there is no baffle in the opening, so that the mop assembly 2 can extend laterally.

[0056] The mop assembly 2 is installed in the mop mounting groove 11, and the mop assembly 2 is fitted with the groove wall of the mop mounting groove 11, and the mop assembly 2 can move laterally relative to the groove wall of the mop mounting groove 11. Specifically, the mop assembly 2 includes a main structure 21 and a cleaning mop 22. The main structure 21 is the main mounting part of the mop assembly 2, which can be a cover or a cover plate, etc. The cleaning mop 22 is installed at the bottom of the main structure 21. The cleaning mop 22 can be a long strip mop, a disc mop or a roller mop. The cleaning mop 22 can be connected to the main structure 21 with a detachable structure, and the cleaning mop 22 only mops the floor as the sweeping robot runs. The cleaning mop 22 can also be connected to the main structure 21 with a pivot structure (such as a pivot shaft), and a mop drive module is configured on the main structure 21 to drive the cleaning mop 22 to roll or rotate to improve the cleaning and mopping effect.

[0057] When the sweeping robot is in the mopping state (cleaning state), the cleaning mop 22 is attached to the floor to clean the floor.

[0058] The driving mechanism 3 is connected between the housing 1 and the main structure 21 , and is used to drive the main structure 21 to move laterally, thereby driving the cleaning mop 22 to extend from a notch at one end of the mop installation slot 11 or to retract and return to its original position.

[0059] The driving mechanism 3 can be a motor driving mechanism, a cylinder driving mechanism, etc. The output end of the driving mechanism 3 is connected to the main structure 21 to drive the main structure 21 to move laterally. The driving mechanism 3 can be installed in the mop installation groove 11, or installed outside the mop installation groove 11.

[0060] The mop assembly 2 has a first cleaning state and a second cleaning state. The first cleaning state is a common cleaning state or a main cleaning state, and the second cleaning state is a corner / dead corner cleaning state or a secondary cleaning state.

[0061] When the user chooses to use the first cleaning state according to the actual scenario, that is, when there is no need to clean the dead corners of the floor and the wall, the driving mechanism 3 is in the initial state or the default state, and the cleaning mop 22 is in the mop mounting slot 11. It will not translate out of the mop mounting slot 11, and it only cleans the area where the body of the sweeping robot passes.

[0062] When the mop assembly 2 is in the second cleaning state, one end of the cleaning mop 22 extends out of the outside of the mop installation slot 11 .

[0063] When the user chooses to use the second cleaning state according to the actual scenario, that is, when the dead corners of the floor and the wall need to be cleaned, the driving mechanism 3 receives the command sent by the control module of the sweeping robot, and the driving mechanism 3 starts to move, driving the main structure 21 to move horizontally toward the notch at one end of the mop installation slot 11 until it extends to a preset length, for example, any length between 5cm and 10cm. At this time, one end of the cleaning mop 22 also extends out of the mop installation slot 11 by a preset length, so that the sanitary dead corners between the floor and the wall can be cleaned.

[0064] After the cleaning of the sanitary dead corners is completed, the user can choose to return to the first cleaning state or select a reset command, and the driving mechanism 3 drives the mop assembly 2 to reset so as to store the mop assembly 2 into the mop mounting groove 11. The control module of the sweeping robot can also automatically control the driving mechanism 3 to issue a command, and the driving mechanism 3 drives the mop assembly 2 to reset so as to store the mop assembly 2 into the mop mounting groove 11.

[0065] In summary, the mop device provided by the utility model includes a shell 1, a mop assembly 2 and a driving mechanism 3. The mop assembly 2 is intermittently assembled in the mop mounting groove 11. The mop assembly 2 includes a main structure 21 and a cleaning mop 22. The driving mechanism 3 is connected to the main structure 21 in a transmission manner, and is used to drive the main structure 21 to translate along the length direction of the mop mounting groove 11, thereby driving the cleaning mop 22 to extend out of the mop mounting groove 11 to clean the dead corners. The driving mechanism 3 can drive the cleaning mop 22 to remain in the mop mounting groove 11 as needed to achieve normal cleaning, or it can drive the cleaning mop 22 to extend out of the mop mounting groove 11 as needed to achieve cleaning of the dead corners, thereby meeting the user's various cleaning needs. When the sweeping robot returns to its position, the cleaning mop 22 is stored in the mop mounting groove 11, which will not be seen by the user and will not take up additional space, thereby improving the performance of the product and the user's experience.

[0066] In one embodiment, if Figure 1-4 and Figure 7-12 As shown, the driving mechanism 3 includes a driving motor 31 , a transmission gear 32 connected to the rotating shaft of the driving motor 31 , and a transmission rack 33 meshing with the transmission gear 32 .

[0067] The driving motor 31 is fixedly connected to the housing 1 , the transmission rack 33 is arranged along the length direction of the mop mounting groove 11 , and the transmission rack 33 is slidably connected to the housing 1 .

[0068] A connecting arm 23 is provided on the main structure 21 , and a coupling portion 34 for cooperating with the connecting arm 23 is provided on the transmission rack 33 . The connecting arm 23 cooperates with the coupling portion 34 and can be driven by the transmission rack 33 to translate.

[0069] In this embodiment, the driving mechanism 3 adopts a motor driving mechanism, which includes a driving motor 31, a transmission gear 32 and a transmission rack 33. The driving motor 31 is fixedly mounted on the housing 1 through a connecting structure, and the transmission gear 32 is mounted on the rotating shaft of the driving motor 31. The transmission rack 33 is arranged horizontally, and extends along the length direction of the mop mounting groove 11. The transmission rack 33 is slidably assembled with the housing 1, and can slide along the length direction of the mop mounting groove 11. The transmission rack 33 can be assembled below the top plate of the mop mounting groove 11, and can also be installed above the top plate of the mop mounting groove 11.

[0070] A connecting arm 23 is provided at the top of the main structure 21, and a coupling portion 34 for cooperating with the connecting arm 23 is provided on the transmission rack 33. The coupling portion 34 can be a connecting buckle, a connecting sleeve, a connecting frame, a connecting hole, etc. The upper end of the connecting arm 23 is connected to the coupling portion 34, and when the transmission rack 33 translates, the coupling portion 34 will drive the connecting arm 23 to translate.

[0071] When the cleaning mop 22 needs to be extended, the driving motor 31 runs forward, causing the transmission rack 33 to move toward the notch at one end of the mop mounting slot 11, and the coupling portion 34 drives the connecting arm 23 to move synchronously, and the connecting arm 23 drives the main structure 21 to move synchronously, and the main structure 21 drives the cleaning mop 22 to extend from the notch at one end of the mop mounting slot 11 to clean dead corners.

[0072] When the cleaning mop 22 needs to be reset, the driving motor 31 rotates in the reverse direction, causing the transmission rack 33 to move from the notch at one end of the mop mounting slot 11 to the middle and reset. The coupling portion 34 drives the connecting arm 23 to move synchronously, and the connecting arm 23 drives the main structure 21 to move synchronously. The main structure 21 drives the cleaning mop 22 to retract into the mop mounting slot 11.

[0073] In one embodiment, if Figure 3-6 As shown, a guide groove 12 extending along the length direction of the mop mounting groove 11 is provided on the top of the housing 1 , and a guide limit hole 121 extending along the length direction of the mop mounting groove 11 is provided on the bottom plate of the guide groove 12 .

[0074] The transmission rack 33 is loosely fitted in the guide groove 12 , and the connecting arm 23 loosely passes through the guide limiting hole 121 and is fitted with the transmission rack 33 .

[0075] In this embodiment, the transmission rack 33 is mounted above the top plate of the mop mounting slot 11. Specifically, a guide slot 12 is provided on the top of the housing 1. The guide slot 12 is located on the top plate of the mop mounting slot 11. The guide slot 12 extends along the length direction of the mop mounting slot 11. The transmission rack 33 is loosely fitted in the guide slot 12. The guide slot 12 guides the lateral translation of the transmission rack 33.

[0076] The bottom plate of the guide slot 12 is the top plate of the mop installation slot 11. In order to limit the lateral translation of the mop assembly 2, a guide limit hole 121 is provided on the bottom plate of the guide slot 12, and the guide limit hole 121 extends along the length direction of the mop installation slot 11. During assembly, the connecting arm 23 passes through the guide limit hole 121 and cooperates with the transmission rack 33.

[0077] Take the extension to the right as an example: when the connecting arm 23 is driven to move to the right, the cleaning mop 22 is driven to extend to the right. When the connecting arm 23 contacts the hole wall on the right side of the guide limit hole 121 and cannot continue to move to the right, it means that the cleaning mop 22 has extended to the right to the maximum length. When the cleaning mop 22 is driven to return to the left, after the connecting arm 23 contacts the hole wall on the left side of the guide limit hole 121 and cannot continue to move to the left, it means that the cleaning mop 22 has retracted to the limit position and the cleaning mop 22 is completely in the mop installation slot 11.

[0078] In one embodiment, if Figure 3-4 and Figure 7-12 As shown, a connecting arm 23 is provided at both ends of the main structure 21, and a coupling portion 34 is provided at both ends of the transmission rack 33. The two connecting arms 23 cooperate with the two coupling portions 34 respectively, which is beneficial to improving the stability of driving the mop assembly 2 to move in translation.

[0079] In one embodiment, if Figure 8-12 As shown, the coupling portion 34 includes a frame structure 341 connected to the end of the transmission rack 33 and a guide rail 342 provided in the frame structure 341 and used to drive the connecting arm 23 to move up and down.

[0080] The connecting arm 23 is slidably connected to the guide rail 342 . When the connecting arm 23 is at the end of the guide rail 342 , the end plate of the frame structure 341 blocks the connecting arm 23 and can drive the connecting arm 23 to translate.

[0081] When the mop assembly 2 is in an initial state, the cleaning mop 22 is in a raised state in the mop installation slot 11 .

[0082] When the mop assembly 2 is in the first cleaning state, the cleaning mop 22 is in the mop installation slot 11 and is in a descending state.

[0083] When the mop assembly 2 is in the second cleaning state, one end of the cleaning mop 22 extends out of the outside of the mop installation slot 11 and is in a descending state.

[0084] In this embodiment, the driving mechanism 3 can drive the mop assembly 2 to move horizontally, and can also drive the mop assembly 2 to move up and down, so as to meet the needs of different application scenarios.

[0085] For example, when the sweeping robot is in an initial state (default state, charging state, self-cleaning state, etc.), the driving mechanism 3 is in an initial state, so that the mop assembly 2 is raised in the mop installation slot 11, and the cleaning mop 22 is in a state of being raised off the ground and does not touch the floor. When the sweeping robot is in a vacuuming state, the driving mechanism 3 is in an initial state, so that the mop assembly 2 is raised in the mop installation slot 11, and the cleaning mop 22 is in a state of being raised off the ground to avoid wetting the floor and affecting vacuuming.

[0086] When the sweeping robot is mopping the floor (normal cleaning), when the mop assembly 2 is in the first cleaning state, the driving mechanism 3 drives the mop assembly 2 to descend, so that the cleaning mop 22 is in a descending grounded state.

[0087] When the sweeping robot is mopping the floor (dead corner cleaning), when the mop assembly 2 is in the second cleaning state, the driving mechanism 3 drives the lowered mop assembly 2 to move laterally, so that one end of the cleaning mop 22 extends out of the outside of the mop installation slot 11.

[0088] When the sweeping robot returns to the initial state, the driving mechanism 3 drives the mopping assembly 2 to reset, including rising off the ground to reset and / or moving laterally to retract to reset.

[0089] Specifically, the structure for driving the mop assembly 2 to move horizontally and to rise and fall is integrated in the joint 34. The joint 34 includes a frame structure 341 and a guide rail 342. The frame structure 341 is connected to the end of the transmission rack 33, and the guide rail 342 is arranged in the frame structure 341, and can drive the connecting arm 23 to rise and fall. The guide rail 342 can adopt a convex rail with one end high and the other end low, or a guide rail groove with one end high and the other end low. The connecting arm 23 is slidably connected to the convex rail or the guide rail groove. When the connecting arm 23 slides from the lower end of the guide rail 342 to the higher end, the connecting arm 23 drives the mop assembly 2 to rise as a whole. When the connecting arm 23 slides from the higher end of the guide rail 342 to the lower end, the connecting arm 23 drives the mop assembly 2 to descend as a whole.

[0090] When the connecting arm 23 is at the lower end of the guide rail 342, one side end plate of the frame structure 341 blocks the connecting arm 23 and can push the connecting arm 23 to move horizontally toward one side slot of the mop mounting slot 11, thereby driving the mop assembly 2 to move outward as a whole, so that the cleaning mop 22 extends out of the mop mounting slot 11 in the lowered state to clean the sanitary dead corner between the floor and the wall.

[0091] When the connecting arm 23 is at the higher end of the guide rail 342, the end plate on the other side of the frame structure 341 blocks the connecting arm 23 and can push the connecting arm 23 to move toward the middle of the mop mounting slot 11, thereby driving the mop assembly 2 to move inward as a whole, so that the cleaning mop 22 returns to the mop mounting slot 11 in the raised state and resets to the initial state.

[0092] In one embodiment, if Figure 7-12 As shown, the frame structure 341 includes a first end plate 3411 and a second end plate 3412 arranged at intervals along the length direction of the mop mounting groove 11, a first end 3421 of the guide rail 342 is connected to the first end plate 3411, and a second end 3422 of the guide rail 342 is connected to the second end plate 3412, and the guide rail 342 gradually rises in the direction from the first end 3421 to the second end 3422 of the guide rail 342.

[0093] The upper end of the connecting arm 23 has a hanging plate 231 , which rests on the guide rail 342 and can slide relative to the guide rail 342 .

[0094] When the hanging plate 231 is at the first end 3421 of the guide rail 342 , the first end plate 3411 blocks the hanging plate 231 .

[0095] When the hanging plate 231 is at the second end 3422 of the guide rail 342 , the second end plate 3412 blocks the hanging plate 231 .

[0096] In this embodiment, the frame structure 341 includes a first end plate 3411, a second end plate 3412 and two side plates 3413. The first end plate 3411 and the second end plate 3412 are arranged at intervals along the length direction of the mop installation groove 11, and the side plates 3413 extend along the length direction of the mop installation groove 11. The first end plate 3411 and the second end plate 3412 are connected between the two ends of the two side plates 3413.

[0097] Taking the extension direction of the mop assembly 2 as a standard, the end of the transmission rack 33 facing the extension direction of the mop assembly 2 is defined as the proximal end, and the end of the transmission rack 33 facing the extension direction of the mop assembly 2 is defined as the distal end. The second end plate 3412 of the frame structure 341 at the distal end side of the transmission rack 33 is connected to the distal end of the transmission rack 33, and the first end plate 3411 of the frame structure 341 at the proximal end side of the transmission rack 33 is connected to the proximal end of the transmission rack 33.

[0098] The guide rail 342 is connected to the side plate 3413, and the guide rail 342 gradually rises along the extension direction of the mop assembly 2. Specifically, the guide rail 342 includes a lower first end 3421 and a higher second end 3422, the first end 3421 is connected to the first end plate 3411, and the second end 3422 is connected to the second end plate 3412. The first end 3421 and the second end 3422 can be a section of a flat plate, and the guide rail body connected between the first end 3421 and the second end 3422 can be an inclined plate.

[0099] The upper end of the connecting arm 23 has a hanging plate 231, and the hanging plate 231 is connected to the connecting arm 23 in an inverted L shape or a T shape. The hanging plate 231 is placed on the guide rail 342, and the hanging plate 231 can slide on the guide rail 342.

[0100] When the hanging plate 231 is at the first end 3421 of the guide rail 342, the first end plate 3411 blocks the hanging plate 231, and can push the hanging plate 231 to move laterally toward the proximal side, so as to eventually drive the cleaning mop 22 to extend. When the hanging plate 231 is at the second end 3422 of the guide rail 342, the second end plate 3412 blocks the hanging plate 231, and can push the hanging plate 231 to move laterally toward the distal side, so as to drive the cleaning mop 22 to retract.

[0101] When the mop assembly 2 is in the initial state, the cleaning mop 22 is lifted off the ground and stored in the mop mounting slot 11 . At this time, the transmission gear 32 is approximately in the middle position of the transmission rack 33 , and the hanging plate 231 is on the second end 3422 of the guide rail 342 .

[0102] When the driving mechanism 3 drives the mop assembly 2 to descend, the transmission rack 33 is driven to translate toward the proximal side, and the guide rail 342 moves integrally until the hanging plate 231 falls on the first end 3421 of the guide rail 342. At this time, the mop assembly 2 is in a descending state, and the cleaning mop 22 is in the mop mounting slot 11 and is in a descending grounding state.

[0103] When the mop assembly 2 in the above state needs to be reset, the drive motor 31 runs in the reverse direction to drive the transmission rack 33 to move toward the distal side, and the guide rail 342 moves integrally until the hanging plate 231 falls on the second end 3422 of the guide rail 342, completing the upward reset.

[0104] When the driving mechanism 3 continues to drive the transmission rack 33 to move toward the proximal side, the first end plate 3411 will block the hanging plate 231 and push the hanging plate 231 to move laterally toward the proximal side, and the connecting arm 23, the main structure 21 and the cleaning mop 22 move laterally as a whole, and finally drive the cleaning mop 22 to extend.

[0105] When the mop assembly 2 in the above state needs to be reset, the drive motor 31 runs in the reverse direction, driving the transmission rack 33 to move toward the distal side, and the guide rail 342 moves integrally until the hanging plate 231 falls on the second end 3422 of the guide rail 342, and the ascending reset is completed. At this time, the second end plate 3412 blocks the hanging plate 231, and the drive motor 31 continues to run in the reverse direction. The second end plate 3412 will block the hanging plate 231 and push the hanging plate 231 to move horizontally toward the distal side, and the connecting arm 23, the main structure 21 and the cleaning mop 22 move horizontally integrally, and finally drive the end of the cleaning mop 22 to retract into the mop installation slot 11, completing the retraction and translation reset.

[0106] In one embodiment, if Figure 8-12 As shown, two guide rails 342 are provided in the frame structure 341 . The two guide rails 342 are arranged at intervals, and a guide groove 343 is formed between the two guide rails 342 .

[0107] The connecting arm 23 passes through the guide slot 343 , and the hanging plate 231 rests on the two guide rails 342 .

[0108] In this embodiment, a guide rail 342 is provided on the inner side of each of the two side panels 3413, and a guide groove 343 is formed between the two guide rails 342. The hanging plate 231 is connected to the connecting arm 23 in a T-shape, and the connecting arm 23 passes through the guide groove 343, which can provide guidance for the movement of the connecting arm 23. The hanging plate 231 is placed on the two guide rails 342, which improves the stability of the hanging plate 231 sliding relative to the guide rails 342.

[0109] In one embodiment, if Figure 4 and Figure 7 As shown, an elastic pressing member 24 is provided between the main structure 21 and the transmission rack 33 and / or the housing 1. When the mop assembly 2 is driven to descend, the elastic pressing member 24 acts as a booster and keeps the cleaning mop 22 grounded and clean.

[0110] The elastic pressing member 24 can be an elastic sheet, a spring or the like, and is connected between the main structure 21 and the transmission rack 33. The coupling portion 34 is considered as a part of the transmission rack 33, and the elastic pressing member 24 can also be directly connected between the main structure 21 and the coupling portion 34.

[0111] In one embodiment, if Figure 4 and Figure 7 As shown, the elastic pressing member 24 is a spring 241, and the spring 241 is sleeved on the connecting arm 23. Specifically, the upper end of the spring 241 is connected to the bottom of the frame structure 341, the lower end of the spring 241 is connected to the top of the main structure 21, and the connecting arm 23 passes through the spring 241. The lifting and lowering of the mop assembly 2 depends entirely on the relative position between the connecting arm 23 and the joint 34. The spring 241 is sleeved on the connecting arm 23, which can achieve a better and more direct downward pressing effect.

[0112] An embodiment of the utility model provides a sweeping robot, comprising the mopping device described in any of the above embodiments. Specifically, the mopping device is installed in the rear half of the body of the sweeping robot, and the shell 1 can be integrated with the body or connected to the body by a connecting structure to be installed in the cavity of the body.

[0113] As needed, the above technical solutions can be combined to achieve the best technical effect.

[0114] The above are only the principles and preferred embodiments of the present invention. It should be noted that, for those skilled in the art, on the basis of the principles of the present invention, several other modifications can be made, which should also be considered as the protection scope of the present invention.
