[0033] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the following embodiments are combined with the attached Figures 1 to 10 The mopping mechanism applied to the automatic cleaning robot and the sweeping robot provided by the present invention are specifically described.

[0034] Embodiment 1,

[0035] See also Figures 1 to 5 As shown in , this embodiment provides a mopping mechanism for an automatic cleaning robot installed at the rear end of a robot body 1 of the automatic cleaning robot, wherein the mopping mechanism includes:

[0036] A mounting bracket 2 is arranged in the robot body 1;

[0037] A rotating assembly is rotatably mounted in the mounting bracket 2;

[0038] The first driving motor 7 is installed on the mounting bracket 2 and is in transmission connection with the rotating assembly to drive the rotating assembly to rotate;

[0039] The crawler-type cleaning cloth 6 is sleeved outside the rotating assembly and rotates therewith;

[0040] The lifting mechanism is installed inside the robot body 1 to drive the mounting bracket 2 to lift longitudinally.

[0041] In specific use, first, the lifting mechanism drives the mounting bracket 2 and the crawler-type cleaning cloth 6 to descend to contact the ground, and the floor is scrubbed as the robot body 1 moves. After the crawler-type cleaning cloth 6 rotates one week along with the rotating assembly, since dirt has adhered to its surface, the problem of secondary floor pollution is likely to occur when scrubbing the floor again. At this time, the lifting mechanism drives the mounting bracket 2 and the crawler-type cleaning cloth 6 to lift and retract, and the robot body 1 records this position as the break point position. Then, the robot body 1 moves to a specially set cleaning seat in the room (equipped with a mechanism for cleaning, dehumidifying, and drying the crawler-type cleaning cloth 6 of the present invention) or a dedicated cleaning tank to perform the operation of decontaminating and cleaning the crawler-type cleaning cloth 6. During this period, the lifting mechanism can drive the mounting bracket 2 and the crawler-type cleaning cloth 6 to appropriately adjust their positions, such as descending into an ultrasonic cleaning tank, and the rotating assembly rotates to comprehensively clean the cleaning cloth. After the cleaning is completed, the robot body 1 moves to the above break point position again to scrub the floor, and so on.

[0042] Based on the above technical solution, the mopping mechanism includes a mounting bracket 2, a rotating assembly, a first driving motor 7, a crawler-type cleaning cloth 6, and a lifting mechanism, which can avoid the problem of secondary pollution during the process of the cleaning cloth scrubbing the floor, so that the cleanliness of the scrubbed floor is higher.

[0043] In a preferred embodiment, the rotating assembly includes a driving wheel 3 and a driven wheel 4 rotatably installed inside the mounting bracket 2. The output shaft of the first driving motor 7 is in transmission connection with one end of the driving wheel 3, and the crawler-type cleaning cloth 6 is sleeved outside the driving wheel 3 and the driven wheel 4. Specifically, the transmission connection between the driving wheel 3 and the first driving motor 7 is realized by means of a belt pulley and a belt, but it can also be realized by a gear set, and it is not limited thereto. Further, the lifting mechanism includes a second driving motor 10 fixedly installed inside the robot body 1 and a push rod 11 sleeved on the output shaft of the second driving motor 10. An arc-shaped plate 12 integrally shaped like a "冂" is provided on the mounting bracket 2, and the push rod 11 extends into the arc-shaped plate 12 and can lift the mounting bracket 2 under the action of the second driving motor 10. In specific applications, the output shaft of the second driving motor 10 drives the push rod 11 to rotate, and the push rod 11 rotates in the arc-shaped plate 12 to such as Figure 1When the mounting bracket 2 is in the state shown, the mounting bracket 2 is lifted, and when the mounting bracket 2 is rotated clockwise by 90 degrees or more, the mounting bracket 2 naturally descends under the action of gravity (such as Figure 4 As shown in ), the lifting function is realized. And its structure can also be directly realized by an electric push rod, but it is not limited to this. Further, the two ends of the driving wheel 3 extend out of the two sides of the mounting bracket 2 through the central axis and are rotatably connected to the inside of the robot body 1, and the driving wheel 3 is located in the front side direction of the driven wheel 4, so that the front end of the rotating component is pivotally connected to the robot body 1, and the rear end is used as a free end that can be lifted and lowered, that is, only the rear end of the mopping mechanism can be lifted and lowered, and the lifting state is as shown in FIG. Fig. 9 and Fig.10 As shown in , it is a more preferred solution in this embodiment, but in fact, based on the above solution, it can also be a structure of overall lifting.

[0044] As a further preferred embodiment, a rubber transmission belt 5 is also mounted outside the driving wheel 3 and the driven wheel 4, and a track-type wiping cloth 6 is mounted outside the rubber transmission belt 5, which can effectively prevent slipping. Specifically, the inner side wall of the rubber transmission belt 5 forms an inner toothed belt structure, and the outer peripheries of the driving wheel 3 and the driven wheel 4 are provided with a gear structure matching the structure of the inner toothed belt, which further prevents slipping. Furthermore, the track-type wiping cloth 6 is a strip of cloth, and the two ends of the strip of cloth have a connecting structure that can be connected into one, and the connecting structure can be a variety of structures such as Velcro, zipper, magic buckle, etc. Based on the above structure, the main structure and steps of the quick installation and removal of the crawler wiping cloth 6 are: a slot for inserting one end of the crawler wiping cloth 6 is set on the rubber transmission belt 5, one end of the crawler wiping cloth 6 is inserted into the slot or bonded to the velcro, the driving wheel 3 is driven to rotate one circle, and then the other end of the crawler wiping cloth 6 is connected to one end of the crawler wiping cloth 6, so that it becomes a whole and is sleeved on the rubber transmission belt 5. The disassembly method is carried out in the opposite way, the state of the two ends of the crawler wiping cloth 6 being connected is released, and it is directly pulled out or taken out by the reverse rotation of the driving wheel 3, making the disassembly method extremely convenient. Further, an ultraviolet light source (not shown in the figure) is also installed on the side of the mounting bracket 2 facing the crawler wiping cloth 6, which is used to further sterilize the crawler wiping cloth 6, especially after completing the sweeping and cleaning actions, the problem of bacterial growth during long-term storage can be avoided after the sterilization operation, and the ultraviolet light source is electrically connected to the central control system in the robot body 1.

[0045] As a further preferred embodiment, the two ends of the central axis of the driving wheel 3 extend out of the mounting bracket 2 and are respectively rotatably connected to a sliding seat 8, and each sliding seat 8 is horizontally provided with a channel, and a guide rod 9 is respectively penetrated in the channel, and the two ends of the guide rod 9 are fixedly installed in the robot body 1, and the robot body 1 is also provided with a third driving motor (not shown in the figure) for driving the mounting bracket 2 to move back and forth along the guide rod 9, and the output shaft of the third driving motor is connected to the front end of the mounting bracket 2 by transmission, so that the effect of scrubbing the floor is better. Specifically, the third driving motor can be an electric push rod, which directly drives the mounting bracket 2 to move back and forth, and the head end of the rod is hinged to the front end of the mounting bracket 2, or it can be a common motor, and it is meshed with the spur rack or worm gear arranged on the front side of the mounting bracket 2 through the reduction gear set and the transmission gear in turn, which can also achieve the purpose of linear movement.
