The present embodiment provides a cleaning robot 10 capable of solving the problem that the cleaning robot 10 having the floor mopping function cannot effectively wipe the floor wheel mark in the related art.

Referring to fig. 1 and 2, fig. 1 is a schematic view of a cleaning robot 10 in a first view according to the present embodiment. Fig. 2 is a schematic view of the cleaning robot 10 in the second perspective view according to the present embodiment.

The cleaning robot 10 includes a chassis 11, traveling wheels 12, and a mop mechanism 13.

The traveling wheels 12 are provided to the chassis 11, and are configured to move the cleaning robot 10 on the ground. The mop mechanism 13 is disposed on the chassis 11 and located at a rear side of the traveling wheels 12 (based on a traveling direction of the cleaning robot 10 during normal operation, the traveling direction is forward, otherwise, the traveling direction is rear side), and the mop mechanism 13 is configured to erase a traveling trace of the ground and the traveling wheels 12.

The above-mentioned scheme provides a cleaning robot 10, and it can clear away the wheel mark that its driving caused in the process of cleaning, guarantees the cleaning performance. The cleaning robot 10 moves on the ground by traveling wheels 12 provided on a chassis 11 to perform a cleaning work. In order to erase the trace of the walking wheel 12 and wipe the ground, the cleaning robot 10 further comprises a mop mechanism 13, the mop mechanism 13 is located at the walking rear side of the walking wheel 12, the walking wheel 12 drives the chassis 11 to advance so that the cleaning robot 10 works, the mop mechanism 13 also moves along with the walking wheel 12, and the walking wheel is located behind the walking wheel 12, so that the walking trace of the ground and the walking wheel 12 is erased, and the cleaning effect is guaranteed.

Referring to fig. 1, a middle broom 14 and an edge broom 15 of a cleaning robot 10 are shown in fig. 1.

Wherein the side sweep 15 is located on the traveling front side of the traveling wheels 12. The middle sweeper 14 is located between the side sweeper 15 and the mop mechanism 13, and the middle sweeper 14 is located close to a dust bin inlet 90 of the cleaning robot 10 (the dust bin inlet 90 refers to an inlet of a bin where the cleaning robot 10 collects dust and the like, which is prior art).

The mop mechanism 13 includes a tray 130, a mop cloth 131 disposed on the tray 130, and a driving part 132, wherein the driving part 132 is disposed on the chassis 11 and drives the tray 130 to rotate, so as to drive the mop cloth 131 to wipe the ground and the wheel mark.

In other embodiments, the driving portion 132 may be eliminated, and the tray 130 may be directly rotatably provided on the chassis 11, or the tray 130 may be fixed to the chassis 11. In an exemplary embodiment, when the tray 130 is rotatably disposed on the chassis 11, a bearing may be fixed on the chassis 11, and the tray 130 is embedded in an inner ring of the bearing, so as to rotate the tray 130.

In this embodiment, the driving unit 132 includes a motor 1320 and a sleeve 1321, the motor 1320 is mounted on the chassis 11, one end of the sleeve 1321 is disposed on an output shaft of the motor 1320, and the other end of the sleeve 1321 is detachably connected to the tray 130.

It should be noted that the sleeve 1321 is used to connect the tray 130 and transmit the power of the driving part 132 to the tray 130, and for this reason, in one possible embodiment, a protruding shaft protrudes upward from the tray 130, and the protruding shaft and the sleeve 1321 are in spline connection, so that the tray 130 can be stably rotated between the floor and the chassis 11 under the self-weight of the cleaning robot 10 and the support of the floor. In other embodiments, the motor 1320 may be removably coupled to the tray 130 via other structures.

Referring to fig. 1, two road wheels 12 and one universal wheel 16 are shown in fig. 1, and in order to wipe the impressions of the two road wheels 12, the number of trays 130 (mops 131 provided on the trays 130) is set correspondingly, and each tray 130 is provided at the rear side of the road wheel 12 corresponding thereto. In other embodiments, the number of the traveling wheels 12 can be adjusted according to the design of the cleaning robot 10 (for example, the number of the traveling wheels 12 is three, four, etc.), and similarly, the number of the trays 130 is also adjusted to ensure the wiping effect.

Referring to fig. 1, the rotation directions of the two trays 130 are shown in fig. 1 (see the arrows marked below the two trays 130), the rotation directions of the two trays 130 are opposite, specifically, the two trays 130 are both rotated outwards based on the center line of the two trays 130, and the purpose is to: when the cleaning robot 10 normally walks and works, the two trays 130 can push dirt or impurities to the outside together, rather than being collected together at a position between the two trays 130, thereby ensuring that a walking path of the cleaning robot 10 is clean and free of dirt.

It should be noted that, in the present embodiment, the number of the motors 1320 is one, and one motor 1320 is disposed in the chassis 11, and drives the two trays 130 to rotate simultaneously through the gear assembly. In other embodiments, the number of motors 1320 may correspond to the number of trays 130, one motor 1320 for each tray 130.

Referring to fig. 3 and 4, fig. 3 is a schematic view of another cleaning robot 10 in the embodiment at a first viewing angle. Fig. 4 is a schematic view of another cleaning robot 10 in the present embodiment from a second perspective.

Fig. 3 and 4 show another cleaning robot 10, which is substantially identical to the cleaning robot 10 described above, with the difference that the mop mechanism 13.

In fig. 3 and 4, the mop mechanism 13 includes a rolling brush 133, and the rolling brush 133 is rollably provided to the chassis 11. Meanwhile, it should be noted that the length of the rolling brush 133 should correspond to the footprint of the road wheels 12, so that the working area of the rolling brush 133 is enough to cover the footprints of all the road wheels 12.

The chassis 11 is provided with a rolling brush slot 110, two ends of the rolling brush 133 are provided with a rotating shaft 1330, and the rotating shaft 1330 is detachably arranged in the rolling brush slot 110. It should be explained that the chassis 11 has two rolling brush slots 110, each rolling brush slot 110 corresponds to the rotation shaft 1330 at one end of the rolling brush 133, the chassis 11 can be recessed to give out a space for accommodating a part of the rolling brush 133, and another part of the rolling brush 133 protrudes out of the chassis 11 for wiping the ground and the wheel mark.

It should be noted that, in the above-described cleaning robot, the chassis 11 has a disc-shaped outline, and in order to improve the cleaning of the cleaning robot 10 at the corners of the wall or various corners in the room, another cleaning robot 10 is provided in the present embodiment, referring to fig. 5, and fig. 5 shows a schematic view of a third cleaning robot 10 in the present embodiment.

In fig. 5, the chassis 11 is formed with an edge contour 11a, and the edge wiper 15 is located at the edge contour 11a (for aesthetic reasons, the chassis in fig. 5 is formed with two edge contours 11a symmetrical to each other, and the edge wiper 15 is located at one of the edge contours 11 a). When the cleaning robot 10 travels to a corner or various indoor corners, dirt at the corner or various indoor corners can be cleaned by adjusting the cleaning position by the traveling wheels 12 and the universal wheels 16 and matching the edge sweeper 15 positioned on the edge contour 11 a.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
