At present, the mopping robot with the cleaning cloth has poor obstacle crossing capability due to the fact that the cleaning cloth needs to be attached to the ground, if obstacles exist on the ground, the cleaning cloth can be blocked, and particularly when the large obstacles are met, the mopping robot can be even stuck. Some current mopping robots are provided with detectors to detect obstacles on the ground, and then an electric lifting structure is used for pushing a carrying disc to rise so as to cross the obstacles. However, when the floor mopping robot is used, the detector often cannot detect all obstacles, or when the floor mopping robot travels faster, the detector misses part of obstacles, or when the rag reaches the obstacles, the electric lifting structure does not drive the carrying disc to lift, so that the obstacle cannot be crossed, and even the floor mopping robot is jammed.

Referring to fig. 1 to 4, a floor mopping device 100 provided by the present application will now be described. The floor mopping device 100 comprises a cleaning cloth 12, a carrying disc 30, a bracket 11, a guide plate 13 and a lifting assembly 20. Wherein:

the cleaning cloth 12 is mounted on the bottom of the carrier plate 30, and the cleaning cloth 12 is supported by the carrier plate 30 so as to be used for mopping the floor.

The boat 30 is coupled to the elevating assembly 20 to support the boat 30 by the elevating assembly 20. And the lifting assembly 20 is connected to the support 11, and the lifting assembly 20 is supported by the support 11, thereby supporting the boat 30 on the support 11.

The guide plate 13 is provided on the front side of the carrier tray 30, and the front side of the carrier tray 30 is a side in the forward direction of the traveling direction of the carrier tray 30 when the wiper 12 wipes the floor, and is also referred to as a front side, and correspondingly, the side in the backward direction of the traveling direction is a rear side. And the guide plates 13 are arranged to extend obliquely upwards from back to front, so that when an obstacle is encountered during mopping, the guide plates 13 can play a role of guiding, the corresponding guide plates 13 are also subjected to the reverse acting force of the obstacle, and the acting force of the obstacle on the guide plates 13 pushes the guide plates 13 upwards, so that the guide plates 13 gradually move to the obstacle even if the guide plates 13 move upwards. Because the guide plate 13 is connected with the carrying disc 30, when the guide plate 13 moves upwards, the front side of the carrying disc 30 is driven to move upwards; the carrying tray 30 is connected to the bracket 11 through the lifting assembly 20, so that when the front side of the carrying tray 30 moves upwards, the lifting assembly 20 drives the rear side of the carrying tray 30 to also move upwards, so that the whole carrying tray 30 rises, and the cleaning cloth 12 is driven to rise to cross an obstacle, thereby improving the obstacle crossing capability. In addition, because the guide plate 13 is used for guiding the front side of the carrying tray 30 to move upwards and the whole carrying tray 30 is driven to move upwards through the action of the lifting assembly 20, better obstacle crossing capability can be realized. When the floor mopping device 100 is applied to a floor mopping robot, obstacle crossing can be realized even if an obstacle is not detected, and the obstacle crossing capability is strong.

Compared with the prior art, the floor mopping device 100 provided by the application has the advantages that the lifting assembly 20 is arranged to connect the carrying disc 30 and the bracket 11, so that the carrying disc 30 can be supported at the bottom of the bracket 11, and the cleaning cloth 12 can be used for mopping the floor to clean; by arranging the guide plate 13 at the front side of the carrying disc 30, the guide plate 13 can drive the carrying disc 30 to move upwards when encountering an obstacle; and then under the effect of lifting unit 20, make the whole of carrier plate 30 rise, in order to realize surmounting the obstacle, the obstacle surmounting ability is strong.

In one embodiment, referring to fig. 1, 3 and 4, the lifting assembly 20 includes a plurality of links 21. The upper end of each link 21 is hinged to the carriage 11 so that the links 21 can rotate on the carriage 11. The lower end of each link 21 is connected to the carrier tray 30 to smoothly support the carrier tray 30 by the plurality of links 21. The plurality of links 21 are arranged in parallel with each other, that is, any adjacent two links 21 are parallel with each other. The connecting rods 21 are arranged in at least two rows, two adjacent rows of connecting rods 21 are arranged at intervals along a first direction, the connecting rods 21 in each row are arranged at intervals along a second direction, the second direction is vertical to the first direction, and therefore two adjacent rows of connecting rods 21, the carrying disc 30 and the support 11 jointly form a parallelogram mechanism, when one connecting rod 21 swings, the connecting rods 21 can be driven to swing synchronously, and the carrying disc 30 is driven to ascend integrally. In addition, the plurality of connecting rods 21 are used for driving the carrying disc 30 to ascend integrally, and the structure is relatively simple, convenient to manufacture and low in cost.

It is understood that the lifting assembly 20 may also be other structures, such as cross-guide rails, and the carrier tray 30 is connected to the bracket 11 by using the cross-guide rails, one rail of the cross-guide rails is fixedly connected to the carrier tray 30, and the other rail of the cross-guide rails is fixed to the bracket 11, so that when the front side of the carrier tray 30 moves upwards, the carrier tray 30 is pushed to ascend integrally due to the guiding function of the cross-guide rails.

In one embodiment, referring to fig. 1, 3 and 4, the first direction is parallel to the front-back direction, that is, any two adjacent rows of the connecting rods 21 are spaced in the front-back direction, that is, when the connecting rods 21 are arranged in two rows, the two rows of the connecting rods 21 are spaced in the front-back direction. When the connecting rods 21 are arranged in three rows, four rows and other rows of connecting rods 21, the rows of connecting rods 21 are arranged at intervals along the front-rear direction. When the guide plate 13 receives the reverse acting force of the obstacle and is transmitted to the connecting rod 21 through the carrying disc 30, the connecting rod 21 can be pushed to swing better, and the labor is saved. It should be understood that the first direction may be inclined to the front-back direction, that is, the first direction may form a certain angle with the front-back direction, so that when the guide plate 13 is pushed upwards, the plurality of links 21 may also be linked to guide the tray 30 to move upwards.

In one embodiment, each link 21 extends from top to bottom in a direction inclined toward the rear side of the boat 30. Since the guide plate 13 is located on the front side of the boat 30, the boat 30 moves, and when the guide plate 13 receives the pushing resistance of the obstacle, the direction of the resistance is upward toward the rear side of the boat 30. The connecting rod 21 is arranged to extend obliquely from top to bottom towards the rear side of the carrying disc 30, so that the pushing resistance of the barrier to the guide plate 13 is vertical to the axial direction of the vertical connecting rod 21 or is closer to the axial direction of the vertical connecting rod 21, and the moment formed by the pushing resistance and the connecting rod 21 is larger, so that the carrying disc 30 is pushed to rise more flexibly.

In one embodiment, referring to fig. 1, 3 and 4, the floor cleaning device 100 further includes a rotating shaft 14, and the connecting rods 21 in at least one row of connecting rods 21 are synchronously connected through the rotating shaft 14, so that the rotating shaft 14 better guides the row of connecting rods 21 to synchronously swing, thereby further balancing the lifting of the load tray 30 and the cleaning cloth 12.

In the embodiment, one row of the connecting rods 21 is connected to a rotating shaft 14, and the rotating shaft 14 drives the row of the connecting rods 21 to synchronously swing, so as to better drive the entire boat 30 to move up or down. It is understood that the rows of connecting rods 21 can be connected in series by the rotating shaft 14. Of course, if the number of the links 21 is three, four, etc., several of the links may be connected in series by using the rotating shaft 14.

In one embodiment, the floor mopping device 100 further comprises a lifting motor 15, wherein the lifting motor 15 is mounted on the bracket 11, and the lifting motor 15 is supported by the bracket 11. The lifting motor 15 is used for driving the connecting rod 21 to swing. Because two rows of connecting rods 21 form a parallelogram mechanism, when the lifting motor 15 drives one connecting rod 21 to swing, other connecting rods 21 can be synchronously driven to swing, and the carrying disc 30 can be driven to lift. The lifting motor 15 is arranged, when the lifting device is used, the connecting rod 21 can be actively driven to swing according to the obstacle on the ground, so that the carrying disc 30 is driven to ascend, and the obstacle can be better crossed.

In one embodiment, when the floor mopping device 100 includes the rotating shaft 14, the lifting motor 15 may be connected to the rotating shaft 14, and the rotating shaft 14 is driven to rotate by the lifting motor 15, so as to drive the row of connecting rods 21 or one or more connecting rods 21 in the row to swing, so as to drive the loading tray 30 to lift. It will be appreciated that the link 21 may also be directly driven to oscillate by the lift motor 15.

In one embodiment, referring to fig. 1, 3 and 4, the floor mopping device 100 further includes a reduction box 16, the reduction box 16 connects the lifting motor 15 and the rotating shaft 14 to facilitate the position layout of the lifting motor 15 and to increase the torque so as to more smoothly drive the connecting rod 21 to swing.

Because the connecting rod 21 swings downwards, the carrying disc 30 is pushed to move downwards, and the lower limiting piece 111 is arranged to limit the downward swinging angle of the connecting rod 21, so that the position height of the carrying disc 30 can be limited, and the force of the cleaning cloth 12 at the bottom of the carrying disc 30 pressing against the ground is further limited, so that the ground can be better mopped.

In one embodiment, referring to fig. 1, 3 and 4, the floor mopping device 100 further includes an upper limiting member 112, the upper limiting member 112 is mounted on the bracket 11, the upper limiting member 112 is used for blocking and limiting the upward swinging angle of the connecting rod 21, that is, the connecting rod 21 swings upward, when the connecting rod 21 hits the upper limiting member 112, the upper limiting member 112 can limit the connecting rod 21 to continue swinging upward, so as to limit the upward swinging angular position of the connecting rod 21. Since the connecting rod 21 swings upwards to push the carrying tray 30 to move upwards, the upper limiting member 112 is provided to limit the upward swinging angle of the connecting rod 21, so as to limit the height of the carrying tray 30, and further avoid the carrying tray 30 from damaging the internal structure of the mopping robot.
