Preferred embodiments of the present application:

as shown in fig. 1, the cleaning robot 1 of the present embodiment includes a body 11, a mop 12, a driving wheel assembly 13, a roller brush assembly 14, and a dust suction fan (not shown). The machine body 11 is provided with a dust suction port (not marked in the figure) communicated with a dust suction fan, and the mop 12, the driving wheel assembly 13, the roller brush assembly 14 and the dust suction fan are arranged on the machine body 11, wherein the mop 12 is used for mopping and cleaning a surface to be cleaned, the driving wheel assembly 13 is used for driving the cleaning robot 1 to move forward, and the roller brush assembly 14 is arranged at the dust suction port and used for sweeping garbage on the surface to be cleaned so as to facilitate the dust suction fan to suck the garbage.

As shown in fig. 2, specifically, the driving wheel assembly 13 includes a driving wheel 131 and a swing arm 132, one end of the swing arm 132 is pivotally connected to the body 11 so that the driving wheel assembly 13 can float up and down with respect to the body 11, and the other end of the swing arm 132 is pivotally connected to the driving wheel 131 so that the driving wheel 131 can roll on the surface to be cleaned while the driving wheel assembly 13 floats up and down. Moreover, the front portion of the driving wheel assembly 13 is pivotally connected to the body 11, that is, one end of the swing arm 132 connected to the body 11 is located at the front side of one end of the swing arm 132 connected to the driving wheel 131 in the front-back direction of the cleaning robot 1, so that it is possible to prevent an external force applied to the driving wheel assembly 13 from directing to the pivot shaft connected to the body 11, and the driving wheel assembly 13 is more likely to float when touching a foreign object.

As shown in fig. 3 and 4, in particular, the roller brush assembly 14 includes a roller brush 141 and a floating bracket 142, the roller brush 141 is pivotally connected to the floating bracket 142 so as to be capable of rolling on a surface to be cleaned to sweep up the garbage on the surface to be cleaned, and the rotational direction of the roller brush 141 is the same as the rotational direction of the driving wheel 131. The floating bracket 142 is provided with a rotation shaft 143, and the entire roller brush assembly 14 is pivotally connected to the cleaning robot 1 through the rotation shaft 143 such that the entire roller brush assembly 14 can move up and down relative to the cleaning robot 1 about the rotation shaft 143. As shown in fig. 1 and 4 in conjunction, the front portion of the roller brush assembly 14 is pivotally connected to the body 11, i.e., the rotation shaft 143 of the roller brush assembly 14 mounted to the cleaning robot 1 is forward relative to the entirety of the roller brush assembly 14 in the front-rear direction of the cleaning robot 1.

Referring to the simplified schematic diagram of fig. 5, the rotating shaft of the driving wheel 131 (the pivot shaft of the driving wheel 131 connected to the swing arm 132) is located below the pivot shaft of the driving wheel assembly 13 connected to the machine body 11 (in terms of the center point of the two shafts), i.e., when the driving wheel assembly 13 floats to the highest position relative to the machine body 11, the rotating shaft of the driving wheel 131 is also located below the pivot shaft of the driving wheel assembly 13. Further, the driving wheel 131 is located at the rear side of the roller brush 141 in the front-rear direction of the cleaning robot 1, so that the driving wheel 131 gradually approaches the roller brush assembly 14 in the front-rear direction of the cleaning robot 1 as the driving wheel assembly 13 floats (e.g., the driving wheel 131 moves from the solid line position to the broken line position in the drawing and then approaches the roller brush assembly 14).

As shown in fig. 5, the rotation axis of the roller brush 141 (the pivot axis of the roller brush 141 connected to the floating bracket 142) is located below (with respect to the center point of the two axes) the pivot axis (i.e., the rotation axis 143) of the roller brush assembly 14 connected to the machine body 11, that is, when the roller brush assembly 14 floats to the highest position relative to the machine body 11, the rotation axis of the roller brush 141 is also located below the rotation axis 143, so that the roller brush 141 gradually approaches the driving wheel assembly 13 in the front-rear direction of the cleaning robot 1 as the roller brush assembly 14 floats (for example, the roller brush 141 moves from the solid line position to the dotted line position in the figure and then approaches the driving wheel assembly 13).

It should be noted that fig. 5 is a simplified schematic view, and the specific installation position of the driving wheel 131 may be overlapped with the roller brush 141 in the left-right direction of the cleaning robot 1 as long as the central axis of the driving wheel 131 is ensured to be behind the central axis of the roller brush 141.

Although not shown in the drawings, in a preferred embodiment of the present embodiment, a first elastic member is provided between the driving wheel assembly 13 and the body 11, and the first elastic member is used for providing a floating force to the driving wheel assembly 13, so that the driving wheel 131 is in closer contact with the surface to be cleaned. Specifically, the first elastic member may be a compression spring, the compression spring and the driving wheel 131 are respectively located at two sides of a pivot shaft of the driving wheel assembly 13, and the compression spring is stretched when the driving wheel assembly 13 floats upwards relative to the machine body 11, so that the driving wheel assembly 13 is driven to float downwards by the acting force of the compression spring on the driving wheel assembly 13.

In addition, a second elastic member is disposed between the roller brush assembly 14 and the body 11, and the second elastic member is used for providing a downward floating force to the roller brush assembly 14, so that the roller brush 141 and the surface to be cleaned are in closer contact. Further, the elastic coefficient of the first elastic member is larger than that of the second elastic member, so that the floating response speed of the roller brush assembly 14 is faster than that of the driving wheel assembly 13, and the roller brush assembly 14 is prevented from influencing the contact between the driving wheel assembly 13 as the main drive and the ground.

In addition, it is preferable that the first elastic member employs a decreasing type spring whose stiffness decreases as the load increases, so that the elastic force applied to the driving wheel assembly 13 by the first elastic member increases as the driving wheel assembly 13 floats downward.

Although not shown, in a preferred embodiment of the present embodiment, the mop 12 is two cleaning disks, the mop 12 is located at the rear side of the roller brush assembly 14, and the mop 12 has a left-side extension and a right-side extension which extend forward to the left and right sides of the roller brush assembly 14, so as to facilitate collecting garbage at the roller brush 141 during the rotation of the two cleaning disks, and then the garbage is swept up by the roller brush 141 and sucked by the dust suction fan.

Referring to fig. 1 to 6, in the cleaning robot 1 of the present embodiment, during the cleaning process of the surface to be cleaned, the rotating driving wheel 131 drives the cleaning robot 1 to travel on the surface to be cleaned, the wiping part 12, the roller brush 141 and the surface to be cleaned are in contact, the wiping part 12 can wipe the surface to be cleaned, and the rotating roller brush 141 can sweep up the garbage on the surface to be cleaned, so that the cleaning robot 1 can suck the garbage. Meanwhile, as shown in fig. 6, when the cleaning robot encounters a terrain with a gradually decreasing slope, such as an arc slope, after the cleaning robot 1 travels on the arc slope, the roller brush 141 contacts an area with a larger slope, and the driving wheel 131 contacts an area with a smaller slope, and when the cleaning robot is on a flat terrain, the roller brush 141 floats relative to the body 11 (for example, moves from the dotted line position to the solid line position in fig. 6), and the driving wheel 131 floats relative to the body 11 (for example, moves from the dotted line position to the solid line position in fig. 6), so that the positions of the roller brush 141 and the driving wheel 131 are closer, that is, the slope of the contact area of the roller brush 141 and the slope of the contact area of the driving wheel 131 are closer, so that the direction of the acting force of the arc slope on the cleaning robot 1 is closer, that the resultant force of the cleaning robot 1 driving the cleaning robot 1 to advance is larger, and the cleaning robot 1 is helpful for passing over the terrain with a gradually decreasing slope, such as an arc slope. Meanwhile, the rotation direction of the roller brush 141 is the same as the rotation direction of the driving wheel 131 (as shown by the arrow direction in fig. 6), so that the roller brush and the driving wheel 131 together provide an assisting force for the advance of the cleaning robot 1, further improving the ability of the cleaning robot 1 to cross the arc slope terrain.

It can be understood by those skilled in the art that by pivotally connecting the front portion of the driving wheel assembly 13 to the machine body 11, the external force applied to the driving wheel assembly 13 can be prevented from being directed to the pivotal axis connected to the machine body 11, so that the driving wheel assembly 13 can be more easily floated when encountering a foreign object.

Further, in the process that the cleaning robot 1 crosses a convex surface to be cleaned or an obstacle with gradually reduced slope such as an arc slope, the roller brush 141 relatively close to the front is in contact with an area with a smaller slope, the driving wheel 131 relatively close to the rear is required to be in contact with an area with a larger slope, when the cleaning robot 1 is in a smooth terrain, the driving wheel 131 descends, the descending driving wheel 131 is close to the roller brush 141, meanwhile, the roller brush 141 floats upwards, the floating roller brush 141 is also close to the driving wheel 131, so that the driving wheel 131 and the roller brush 141 are closer, namely, the slope of the contact area of the driving wheel 131 is closer to the slope of the contact area of the roller brush 141, the direction of the acting force of the arc slope on the cleaning robot 1 is closer, the resultant force of the cleaning robot 1 for driving the cleaning robot 1 to advance is larger, the cleaning robot 1 is helped to cross the terrain with gradually reduced slope such as the arc slope, the climbing capability of the cleaning robot 1 is improved, and the range of the terrain which the cleaning robot 1 can cope with is expanded. Moreover, the driving wheel 131 and the roller brush 141 both rotate forward, and together provide the cleaning robot 1 with a forward moving force, further improving the ability of the cleaning robot 1 to traverse terrain with gradually decreasing slopes such as an arc slope.

Further, by providing the first elastic member for driving the driving wheel assembly 13 to descend between the driving wheel assembly 13 and the body 11, the approaching ability of the driving wheel assembly 13 to the roller brush 141 is enhanced, which facilitates the driving wheel 131 of the cleaning robot 1 to approach the roller brush 141 further on a curved slope or the like.

It should be noted that the roller brush assembly 14 may also be pivotally connected at the rear portion to the machine body 11 (i.e., the rotating shaft 143 of the roller brush assembly 14 mounted to the cleaning robot 1 is rearward with respect to the whole of the roller brush assembly 14 in the front-rear direction of the cleaning robot 1), and the rotating shaft of the roller brush 141 is always located above the rotating shaft 143.

The cleaning robot 1 of the present embodiment is further provided with a base station 2, as shown in fig. 1 and 7, the base station 2 includes a base station body 21 and a base 22, the base station body 21 is provided with a cleaning cavity 211, the base 22 is used for guiding the cleaning robot 1 into the cleaning cavity 211, and the bottom of the cleaning cavity 211 is provided with cleaning members such as cleaning ribs, which can clean the mop 12 of the cleaning robot 1. Further, a sealing portion 23 is arranged on the side wall of the cleaning cavity 211, the sealing portion 23 is a flexible strip-shaped structure, and the shape of the sealing portion 23 is matched with that of the cleaning robot 1, so that the sealing portion 23 can be abutted against the cleaning robot 1 and deformed under the extrusion of the cleaning robot 1.

Further, the base station body 21 is provided with the charging terminal 24, the base 22 is provided with an inclined guide surface 221, the cleaning robot 1 is provided with a power receiving terminal (not shown) butted against the charging terminal 24, the guide surface 221 is provided with a positioning groove 222, the driving wheel 131 moves to the edge of the positioning groove 222, the power receiving terminal is contacted with the charging terminal 24, the driving wheel 131 is parked in the positioning groove 222, and the power receiving terminal is pressed against the charging terminal 24, so that the charging terminal moves backward and downward relative to the base station body 21.

Referring to fig. 1 and 7, a baffle 144 is disposed at a rear side of the roller brush 141 of the cleaning robot 1, and when the cleaning robot 1 cleans a surface to be cleaned, the baffle 144 contacts the surface to be cleaned, and the baffle 144 can prevent the edge brush or the roller brush 141 of the cleaning robot 1 from poking dirt on the surface to be cleaned to a rear side of the dust suction opening and prevent air at the rear side of the dust suction opening from entering the dust suction opening, so that air enters the dust suction opening from a front side, a left side and a right side of the dust suction opening 14, and the cleaning robot 1 can provide sufficient suction to the surface to be cleaned. When the cleaning robot 1 enters the washing chamber 211, the baffle 144 is in sealing abutment with the top surface of the base 22.

The use of the base station 2 is explained in connection with fig. 1 and 7:

when the cleaning robot 1 needs to be charged or the mop 12 needs to be cleaned, the cleaning robot 1 moves to the base station 2 by itself, enters the base station 2 in a retreating manner (i.e., the rear side of the cleaning robot 1 where the mop 12 is located enters the base station 2 first), first, the cleaning robot 1 on the surface to be cleaned travels onto the guide surface 221, advances along the guide surface 221, the cleaning robot 1 on the guide surface 221 is in an inclined state, the cleaning robot 1 first abuts against the sealing portion 23 as the cleaning robot 1 travels on the guide surface 221, when the cleaning robot 1 travels to the edge of the positioning groove 222 (i.e., enters the positioning groove 222 or has entered a small portion of the positioning groove 222), the power receiving terminal of the cleaning robot 1 contacts with the charging terminal 24, and as the driving wheel 13 of the cleaning robot 1 moves in the positioning groove 222, the movement state of the cleaning robot 1 moves forward and downward while gradually returning to a horizontal state, during which the charging terminal 24 abutting against the cleaning robot 1 moves backward and moves downward with respect to the base station body 21 with the drive of the cleaning robot 1, so that the charging terminal 24 and the power receiving terminal of the cleaning robot 1 are kept in abutment against the cleaning terminal. After the cleaning robot 1 is stabilized at the lowest point of the positioning groove 222, the wiping member 12 of the cleaning robot 1 contacts with the cleaning rib at the bottom of the cleaning cavity 211, the cleaning robot 1 is tightly abutted to the sealing portion 23, and the baffle 144 at the bottom of the cleaning robot 1 is tightly abutted to the top surface of the base 22. Then, the mop 12 of the cleaning robot 1 is cleaned in the cleaning chamber 211, the liquid under the cleaning robot 1 is blocked by the body 11 and the sealing part 23 and does not splash to other parts of the cleaning robot 1 and the charging terminal 24, and the baffle plate 144 is tightly abutted with the top surface of the base 22, and the baffle plate 144 is positioned between the mop 12 and the roller brush 141, so that the dirty liquid thrown out by the mop 12 can be blocked, the dirty liquid is prevented from flowing to the roller brush 141 of the cleaning robot 1, and simultaneously, the cleaning robot 1 is charged by the base station 2.

As can be understood by those skilled in the art, by movably disposing the charging terminal 24 on the base station body 21, the charging terminal 24 can be abutted with the cleaning robot 1 when the driving wheel 13 of the cleaning robot 1 travels to the edge of the positioning groove 222 (i.e. when the driving wheel is about to enter the positioning groove 222 or enters a small part of the positioning groove 222), and then the charging terminal 24 moves along with the movement of the cleaning robot 1 in the positioning groove 222, so that the cleaning robot and the positioning groove 222 are relatively stationary, thereby effectively reducing the impact force of the cleaning robot 1 on the charging terminal 24 and the friction force between the charging terminal 24 in the descending process, and protecting the charging terminal 31. In addition, in the process that the base station 2 cleans the mopping piece 12 of the cleaning robot 1, the charging terminal 24 abutted to the cleaning robot 1 can move along with the shaking of the cleaning robot 1, so that the charging terminal and the cleaning robot 1 are kept relatively static, the friction between the cleaning robot 1 and the charging terminal 24 is reduced, the charging terminal 24 is protected, and the close contact between the charging terminal 24 and the cleaning robot 1 can be ensured.

Further, by providing a seal portion in contact with the cleaning robot 1, the cleaning liquid can be isolated at the bottom of the cleaning robot 1, and the cleaning liquid at the bottom of the cleaning chamber 211 can be prevented from being splashed onto other parts of the cleaning robot 1 and the charging terminal 24 when the wiper 12 of the cleaning robot 1 is cleaned. The baffle 144 is disposed at the rear side of the roller brush 141, the baffle 144 is in close contact with the top surface of the base 22, and the baffle 144 is located between the mop 12 and the roller brush 141, so that the dirty liquid thrown out by the mop 12 can be blocked, and the dirty liquid can be prevented from flowing to the roller brush 141 of the cleaning robot 1.
