[0043] Currently, for a mopping robot with a mop, since the mop needs to be attached to the ground, the obstacle-crossing ability of the mopping robot becomes worse. If there are obstacles on the ground, they will block the mop. Especially when encountering larger obstacles, the mopping robot may even be stuck. In some current mopping robots, a detector is provided to detect obstacles on the ground, and then an electric lifting structure is used to push the carrier plate upward to achieve obstacle crossing. However, when the mopping robot is in use, the detector often cannot detect all obstacles, or when the mopping robot travels relatively fast, the detector misses some obstacles, or when the mop reaches an obstacle, the electric lifting structure has not yet driven the carrier plate to rise, resulting in the inability to cross the obstacle and even causing the mopping robot to be stuck.

[0044] Please refer to Figures 1 to 4 , and now the mopping device 100 provided by the present application will be described. The mopping device 100 includes a mop 12, a carrier plate 30, a bracket 11, a guide plate 13, and a lifting assembly 20. Among them:

[0045] The mop 12 is installed at the bottom of the carrier plate 30, and the carrier plate 30 is used to support the mop 12 for mopping the floor.

[0046] The carrier plate 30 is connected to the lifting assembly 20 to support the carrier plate 30 through the lifting assembly 20. And the lifting assembly 20 is connected to the bracket 11, and the bracket 11 is used to support the lifting assembly 20, thereby supporting the carrier plate 30 on the bracket 11.

[0047] The guide plate 13 is arranged on the front side of the carrier plate 30. The front side of the carrier plate 30 refers to the side that is closer to the advancing direction of the carrier plate 30 when the mop cloth 12 is mopping the floor, which is also called the front side. Correspondingly, the side that is farther from the advancing direction is the rear side. And the guide plate 13 is inclined upward and extends from the rear to the front. In this way, during the mopping process, when encountering an obstacle, the guide plate 13 can play a guiding role. Correspondingly, the guide plate 13 will also receive a reaction force from the obstacle. The force exerted by the obstacle on the guide plate 13 is to push the guide plate 13 upward, causing the guide plate 13 to gradually move onto the obstacle, that is, the guide plate 13 moves upward. Since the guide plate 13 is connected to the carrier plate 30, when the guide plate 13 moves upward, it will drive the front side of the carrier plate 30 to move upward. And the carrier plate 30 is connected to the bracket 11 through the lifting assembly 20. When the front side of the carrier plate 30 moves upward, it will cause the lifting assembly 20 to drive the rear side of the carrier plate 30 to move upward as well, thereby causing the entire carrier plate 30 to rise and driving the mop cloth 12 to rise to cross the obstacle and improve the obstacle-crossing ability. In addition, since the guide plate 13 is used to guide the front side of the carrier plate 30 to move upward and drive the entire carrier plate 30 to move upward through the action of the lifting assembly 20, a better obstacle-crossing ability can be achieved. When the floor mopping device 100 is applied to a floor mopping robot, even if the obstacle is not detected, the obstacle can be crossed and the obstacle-crossing ability is strong.

[0048] The floor mopping device 100 provided in the present application, compared with the prior art, the floor mopping device 100 of the present application is provided with a lifting assembly 20 connecting the carrier plate 30 and the bracket 11, so that the carrier plate 30 can be supported at the bottom of the bracket 11 for the mop cloth 12 to mop and clean the floor. By arranging the guide plate 13 on the front side of the carrier plate 30, when encountering an obstacle, the guide plate 13 will drive the carrier plate 30 to move upward. Then, under the action of the lifting assembly 20, the entire carrier plate 30 rises to cross the obstacle, and the obstacle-crossing ability is strong.

[0049] In one embodiment, please refer to Figure 1 、 Figure 3 and Figure 4, the lifting assembly 20 includes a plurality of connecting rods 21. The upper end of each connecting rod 21 is hinged to the bracket 11 so that each connecting rod 21 can rotate on the bracket 11. The lower end of each connecting rod 21 is connected to the carrier plate 30 to stably support the carrier plate 30 through the plurality of connecting rods 21. The plurality of connecting rods 21 are arranged in parallel with each other, that is, any two adjacent connecting rods 21 are parallel to each other. The plurality of connecting rods 21 are arranged in at least two rows, and the adjacent two rows of connecting rods 21 are spaced apart in the first direction, and the connecting rods 21 in each row are spaced apart in the second direction, and the second direction is perpendicular to the first direction. In this way, the two adjacent connecting rods 21 in the adjacent two rows and the carrier plate 30 and the bracket 11 together form a parallelogram mechanism. In this way, when one connecting rod 21 swings, it can drive the plurality of connecting rods 21 to swing synchronously, and then drive the overall upward movement of the carrier plate 30. In addition, using the structure of a plurality of connecting rods 21 to drive the overall upward movement of the carrier plate 30, the structure is relatively simple, easy to manufacture, and has a low cost.

[0050] It can be understood that the lifting assembly 20 can also be other structures, such as cross rails. The cross rails are used to connect the carrier plate 30 and the bracket 11. One rail of the cross rails is fixedly connected to the carrier plate 30, and the other rail of the cross rails is fixed to the bracket 11. When the front side of the carrier plate 30 moves upward, due to the guiding action of the cross rails, the carrier plate 30 is pushed to rise as a whole.

[0051] In one embodiment, please refer to Figure 1 , Figure 3 and Figure 4 , the first direction is parallel to the front-rear direction, that is, any two adjacent rows of connecting rods 21 are spaced apart in the front-rear direction. That is to say, when the connecting rods 21 are arranged in two rows, the two rows of connecting rods 21 are spaced apart in the front-rear direction. When the connecting rods 21 are arranged in three rows, four rows or other multiple rows of connecting rods 21, the multiple rows of connecting rods 21 are spaced apart in the front-rear direction. In this way, when the guide plate 13 receives the reverse acting force of the obstacle and is transmitted to the connecting rod 21 through the carrier plate 30, it can better push the connecting rod 21 to swing and is also more labor-saving. It can be understood that the first direction can also be inclined to the front-rear direction, that is, the first direction can form a certain angle with the front-rear direction. In this way, when pushing the guide plate 13 upward, the plurality of connecting rods 21 can also be linked to guide the upward movement of the carrier plate 30.

[0052] In one embodiment, each connecting rod 21 extends obliquely downward from top to bottom in the direction toward the rear side of the carrier plate 30. Since the guide plate 13 is located on the front side of the carrier plate 30, when the carrier plate 30 moves and the guide plate 13 receives the pushing resistance of the obstacle, the direction of this resistance is upward toward the rear side of the carrier plate 30. Arranging the connecting rod 21 to extend obliquely downward from top to bottom in the direction toward the rear side of the carrier plate 30 can make the pushing resistance of the obstacle to the guide plate 13 perpendicular or closer to perpendicular to the axial direction of the connecting rod 21, and then make the moment formed by the pushing resistance and the connecting rod 21 larger, so as to more flexibly push the carrier plate 30 to rise.

[0053] In one embodiment, referring to Figure 1 、 Figure 3 and Figure 4 , the floor mopping device 100 further includes a rotating shaft 14. Each connecting rod 21 in at least one row of connecting rods 21 is synchronously connected by the rotating shaft 14, so that the rotating shaft 14 can better guide the synchronous swinging of this row of connecting rods 21, and further lift the carrier plate 30 and the mop 12 more balancedly.

[0054] In this embodiment, one row of connecting rods 21 is connected to a rotating shaft 14, and the rotating shaft 14 drives the synchronous swinging of this row of connecting rods 21 to better drive the entire carrier plate 30 to move up or down. It can be understood that each row of connecting rods 21 can also be serially connected by the rotating shaft 14. Of course, when the number of connecting rods 21 is set to three rows, four rows, etc., several of them can also be serially connected by the rotating shaft 14.

[0055] In one embodiment, the floor mopping device 100 further includes a lifting motor 15. The lifting motor 15 is installed on the bracket 11, and the bracket 11 supports the lifting motor 15. The lifting motor 15 is used to drive the swinging of the connecting rods 21. Since two rows of connecting rods 21 form a parallelogram mechanism, when the lifting motor 15 drives one connecting rod 21 to swing, it can synchronously drive the other connecting rods 21 to swing, and then drive the carrier plate 30 to lift and lower. By setting the lifting motor 15, during use, according to the obstacles on the ground, the connecting rods 21 can be actively driven to swing to drive the carrier plate 30 to rise and better cross the obstacles.

[0056] In one embodiment, when the floor mopping device 100 includes the rotating shaft 14, the lifting motor 15 can be connected to the rotating shaft 14. By driving the rotating shaft 14 to rotate by the lifting motor 15, one row of connecting rods 21 or one or several connecting rods 21 in a row can be driven to swing, and then the carrier plate 30 can be driven to lift and lower. It can be understood that the lifting motor 15 can also be used to directly drive the connecting rods 21 to swing.

[0057] In one embodiment, referring to Figure 1 、 Figure 3 and Figure 4 , the floor mopping device 100 further includes a speed reducer 16. The speed reducer 16 connects the lifting motor 15 and the rotating shaft 14 to facilitate the layout of the position of the lifting motor 15 and increase the torque to drive the connecting rods 21 to swing more smoothly.

[0058] In one embodiment, the floor mopping device 100 further includes a lower limit member 111. The lower limit member 111 is installed on the bracket 11. The lower limit member 111 is used to block and limit the downward swing angle of the connecting rod 21. That is, when the connecting rod 21 swings downward and touches the lower limit member 111, the lower limit member 111 can limit the connecting rod 21 from continuing to swing downward, so as to limit the angular position of the downward swing of the connecting rod 21. Since the downward swing of the connecting rod 21 will push the carrier plate 30 downward, setting the lower limit member 111 to limit the downward swing angle of the connecting rod 21 can limit the height position of the carrier plate 30, and further limit the pressing force of the mop cloth 12 at the bottom of the carrier plate 30 against the ground, so as to mop the floor better.

[0059] In one embodiment, please refer to Figure 1 、 Figure 3 and Figure 4 , the floor mopping device 100 further includes an upper limit member 112. The upper limit member 112 is installed on the bracket 11. The upper limit member 112 is used to block and limit the upward swing angle of the connecting rod 21. That is, when the connecting rod 21 swings upward and touches the upper limit member 112, the upper limit member 112 can limit the connecting rod 21 from continuing to swing upward, so as to limit the angular position of the upward swing of the connecting rod 21. Since the upward swing of the connecting rod 21 will push the carrier plate 30 upward, setting the upper limit member 112 to limit the upward swing angle of the connecting rod 21 can limit the height position of the carrier plate 30, and further avoid the internal structure of the mopping robot being damaged by the carrier plate 30.

[0060] In one embodiment, the lower limit member 111 and the bracket 11 may be an integrally formed part for convenient processing and manufacturing. Of course, the lower limit member 111 can also be manufactured separately and then fixed on the bracket 11.

[0061] In one embodiment, the upper limit member 112 and the bracket 11 may be an integrally formed part for convenient processing and manufacturing. Of course, the upper limit member 112 can also be manufactured separately and then fixed on the bracket 11.

[0062] In one embodiment, please refer to Figure 1 、 Figure 3 and Figure 4 , the floor mopping device 100 further includes an elastic telescopic mechanism 40. The elastic telescopic mechanism 40 is installed on the lifting assembly 20, and the lifting assembly 20 is used to support the elastic telescopic mechanism 40. The carrier plate 30 is connected to the elastic telescopic mechanism 40 to floatingly support the carrier plate 30 through the elastic telescopic mechanism, so that the carrier plate 30 is supported on the lifting assembly 20 through the elastic telescopic mechanism 40. When in use, the carrier plate 30 can push the mop cloth 12 to elastically press against the ground for mopping and cleaning. In addition, when the ground flatness is poor, the mop cloth 12 can also float along with the terrain for mopping to avoid hard contact. In one embodiment, please refer to Figure 1 、 Figure 4 andFigure 7 The elastic telescopic mechanism 40 includes a connecting cylinder 41, a sliding rod 42, and a spring 43. Among them: One end of the sliding rod 42 is inserted into the connecting cylinder 41, and the spring 43 is installed in the connecting cylinder 41, and the spring 43 elastically pushes against the sliding rod 42 so that the sliding rod 42 can telescopically move elastically along the connecting cylinder 41. The other end of the sliding rod 42 is connected to the lifting assembly 20 to support the elastic telescopic mechanism 40 on the lifting assembly 20. The connecting cylinder 41 is connected to the carrier plate 30 to connect the elastic telescopic mechanism 40 to the carrier plate 30 and support the carrier plate 30 on the elastic telescopic mechanism 40. The elastic telescopic mechanism 40 has a simple structure and is convenient to assemble. It can be understood that the elastic telescopic mechanism 40 can also adopt devices such as elastic telescopic sleeves.

[0063] In one embodiment, when the lifting assembly 20 includes a plurality of connecting rods 21, the elastic telescopic mechanisms 40 are also multiple, and the elastic telescopic mechanisms 40 and the connecting rods 21 are in one-to-one correspondence, and one end of each connecting rod 21 is connected to the corresponding elastic telescopic mechanism 40.

[0064] In one embodiment, one end of the connecting rod 21 can be hinged to the sliding rod 42 of the elastic telescopic mechanism 40 to connect the elastic telescopic mechanism 40 to the corresponding connecting rod 21.

[0065] In one embodiment, please refer to Figure 1 、 Figure 6 and Figure 7 , a connecting head 422 is provided at the upper end of the sliding rod 42 for hinged connection with the connecting rod 21, which is convenient for assembly.

[0066] In one embodiment, a pin shaft 211 is provided at one end of the connecting rod 21, and a shaft hole 4221 is provided on the connecting head 422 of the sliding rod 42. The pin shaft 211 is inserted into the shaft hole 4221 to connect the pin shaft 211 to the sliding rod 42, which is convenient for assembly.

[0067] In one embodiment, ribs 212 are convexly provided on the circumferential side surface of the pin shaft 211, and the ribs 212 extend along the axial direction of the pin shaft 211. In this way, when the pin shaft 211 is inserted into the shaft hole 4221 of the connecting head 422, the contact area between the pin shaft 211 and the inner wall of the shaft hole 4221 can be reduced, and the friction force can be reduced, so that when the pin shaft 211 is adaptively installed in the shaft hole 4221, it can be ensured that the pin shaft 211 can rotate flexibly in the shaft hole 4221.

[0068] In one embodiment, a positioning post 411 is provided in the connecting cylinder 41, and the spring 43 is sleeved on the positioning post 411 to position the spring 43 so that the spring 43 can stably and elastically push against the sliding rod 42.

[0069] In one embodiment, a cavity 421 is formed in the sliding rod 42, and the upper end of the spring 43 is placed in the cavity 421 to position the upper end of the spring 43.

[0070] In one embodiment, refer to Figure 2 , Figure 4 and Figure 5 , the carrier plate 30 includes an upper carrier plate 31 and a lower carrier plate 32, and the lower carrier plate 32 is inserted and connected to the upper carrier plate 31, that is, the lower carrier plate 32 is inserted on the bottom surface of the upper carrier plate 31 to support the lower carrier plate 32 through the upper carrier plate 31.

[0071] The cleaning cloth 12 is installed on the bottom surface of the lower carrier plate 32, and the cleaning cloth 12 is supported by the lower carrier plate 32 for mopping the floor. Inserting the lower carrier plate 32 on the bottom surface of the upper carrier plate 31 can facilitate the removal of the lower carrier plate 32 from the upper carrier plate 31, and further separate the cleaning cloth 12 from the upper carrier plate 31 for cleaning.

[0072] The guiding plate 13 is fixed on the upper carrier plate 31 to support the guiding plate 13 through the upper carrier plate 31. It can be understood that the guiding plate 13 can also be fixed on the lower carrier plate 32 to support the guiding plate 13 through the lower carrier plate 32.

[0073] In one embodiment, slots 311 are respectively provided on opposite sides of the upper carrier plate 31, so that opposite sides of the lower carrier plate 32 can be respectively inserted into the two slots 311 to realize the insertion connection between the lower carrier plate 32 and the upper carrier plate 31. This structure is simple and convenient for processing and manufacturing.

[0074] It can be understood that slots 311 can also be respectively provided on opposite sides of the lower carrier plate 32, so that opposite sides of the upper carrier plate 31 can be respectively inserted into the two slots 311 to realize the insertion connection between the lower carrier plate 32 and the upper carrier plate 31.

[0075] Of course, the lower carrier plate 32 can also be inserted and connected to the upper carrier plate 31 in other ways. For example, a clamping groove can be provided on the bottom surface of the upper carrier plate 31, and the cross-section of the clamping groove is T-shaped, while a plugging rib adapted to the clamping groove is provided on the lower carrier plate 32, and the plugging rib is inserted into the clamping groove to realize the insertion connection between the lower carrier plate 32 and the upper carrier plate 31.
