[0029] Reference is made to Figures 1 to 5The application provides a cleaning robot 100, which comprises a cleaning main body 10, a cleaning brush assembly 30, a first driving wheel 20 and a second driving wheel 20, the first driving wheel 20 and the second driving wheel 20 are rotatably arranged on opposite sides of the cleaning main body 10 to drive the cleaning robot 100 to move, the cleaning brush assembly 30 comprises a first cleaning brush 31 and a second cleaning brush 32, the first cleaning brush 31 is rotatably arranged on the cleaning main body 10 and located between the first driving wheel 20 and the second driving wheel 20, the second cleaning brush 32 is rotatably arranged outside the first driving wheel 20 and / or the second driving wheel 20, the second cleaning brush 32 rotates along the same axis as the first cleaning brush 31, the first cleaning brush 31 is used for cleaning the bottom wall of a region to be cleaned, and the second cleaning brush 32 is used for cleaning the bottom wall and the side wall of the region to be cleaned.
[0030] In specific implementation, the cleaning main body 10 can comprise, but is not limited to, a shell, a main support and a garbage collecting device which are arranged in the shell. The garbage collecting device is detachably connected with the main support, so as to facilitate dumping of garbage.
[0031] In specific implementation, the first driving wheel 20 and the second driving wheel 20 can be symmetrically distributed on opposite sides of the cleaning main body 10, so as to ensure the balance and stability of the structure of the cleaning robot 100.
[0032] Specifically, the cleaning robot 100 can comprise a plurality of wheel groups, one first driving wheel 20 and one second driving wheel 20 form a driving wheel group, all the wheel groups of the cleaning robot 100 can be driving wheel groups, so as to improve the moving efficiency of the cleaning robot 100. Alternatively, at least one of the plurality of wheel groups is a driving wheel group, and other wheel groups can be driven to rotate by the driving wheel group, so that the production cost can be reduced and the structure of the cleaning robot 100 can be simplified.
[0033] Specifically, the first driving wheel 20 and the second driving wheel 20 can be driven to rotate by the same driving motor 40; alternatively, Figures 3 to 5 the first driving wheel 20 and the second driving wheel 20 can be driven to rotate by different driving motors 40, so that the steering can be realized by controlling the differential speed of the first driving wheel 20 and the second driving wheel 20.
[0034] In a specific implementation, the cleaning brush assembly 30 includes a first cleaning brush 31 and a second cleaning brush 32. The first cleaning brush 31 is rotatably arranged between the first driving wheel 20 and the second driving wheel 20, and is used to clean the bottom wall of the area to be cleaned. The second cleaning brush 32 is rotatably arranged outside the first driving wheel 20 and / or the second driving wheel 20, and is used to clean the bottom wall, or the bottom wall and the side wall, of the area to be cleaned. Specifically, when the cleaning robot 100 travels in an open area, both the first cleaning brush 31 and the second cleaning brush 32 clean the bottom wall of the area to be cleaned. When the cleaning robot 100 travels along the edge zone of the area to be cleaned, the second cleaning brush 32 can clean the corner of the intersection of the bottom wall and the side wall, including the partial area of the bottom wall and the side wall, due to the arrangement of the second cleaning brush 32. In this way, by arranging the second cleaning brush 32, the sanitary dead angle caused by the first driving wheel 20 or the second driving wheel 20 traveling along the wall and unable to be cleaned can be cleaned, and the sanitary dead angle of the side wall edge caused by the starting height when the cleaning robot 100 starts to climb the side wall for cleaning can be cleaned.
[0035] Specifically, the second cleaning brush 32 can be arranged only outside the first driving wheel 20, or the second cleaning brush 32 can be arranged only outside the second driving wheel 20, or the second cleaning brush 32 can be arranged outside both the first driving wheel 20 and the second driving wheel 20 to ensure the balance of the structure of the cleaning robot 100. Specifically, the second cleaning brush 32 can be detachably assembled outside the first driving wheel 20 and / or the second driving wheel 20, so as to facilitate the user to assemble according to the needs, and to realize the cleaning and replacement of the second cleaning brush 32.
[0036] The utility model provides a kind of cleaning robot 100 including cleaning main body 10, cleaning brush assembly 30, first drive wheel 20 and second drive wheel 20, first drive wheel 20 and second drive wheel 20 rotatably arranged in the opposite sides of cleaning main body 10, to drive cleaning robot 100 moves;Cleaning brush assembly 30 includes first cleaning brush 31 and second cleaning brush 32, first cleaning brush 31 rotatably arranged on cleaning main body 10, and located between first drive wheel 20 and second drive wheel 20, second cleaning brush 32 rotatably arranged on the outside of first drive wheel 20 and / or second drive wheel 20, second cleaning brush 32 and first cleaning brush 31 rotate along the same axis, first cleaning brush 31 is used to clean the bottom wall of the area to be cleaned, and second cleaning brush 32 is used to clean the bottom wall and side wall of the area to be cleaned.The cleaning process of the cleaning robot 100 is: when cleaning robot 100 is driven to move by first drive wheel 20 and second drive wheel 20, the area to be cleaned between first drive wheel 20 and second drive wheel 20 can be cleaned by first cleaning brush 31, and the area to be cleaned outside first drive wheel 20 and / or second drive wheel 20 can be cleaned by second cleaning brush 32.In the present application, by setting first cleaning brush 31 between first drive wheel 20 and second drive wheel 20, large-area cleaning of the area to be cleaned can be realized, by setting second cleaning brush 32 outside first drive wheel 20 and / or second drive wheel 20, the corner position at the intersection of bottom wall and side wall can be cleaned during the side travel of cleaning robot 100, to optimize cleaning effect and improve cleaning efficiency.
[0037] Referring to Figures 2 to 5 In an embodiment of the present application, the second cleaning brush 32 is arranged eccentrically relative to the center of the first drive wheel 20 and / or the second drive wheel 20. In this way, the freedom of installation and configuration of the second cleaning brush 32 can be improved. For example, if the second cleaning brush 32 is connected in transmission with the first drive wheel 20 and / or the second drive wheel 20 by means of gear engagement, since it is arranged eccentrically, the size of the gear used for engagement with the first drive wheel 20 and / or the second drive wheel 20 can be freely set according to requirements, and it is beneficial to reduce the gear engagement contact area and reduce wear. In addition, the eccentric arrangement is also beneficial to improve the smoothness of transmission of the second cleaning brush 32 with the first drive wheel 20 and / or the second drive wheel 20, and reduce relative vibration.
[0038] Referring to Figures 2 to 4 In an example embodiment of the present application, the cleaning robot 100 further includes two drive motors 40, the two drive motors 40 are respectively connected in transmission with the first drive wheel 20 and the second drive wheel 20, the two ends of the first cleaning brush 31 are respectively connected in transmission with at least one of the first drive wheel 20 and the second drive wheel 20, and the second cleaning brush 32 is connected in transmission with the first drive wheel 20 and / or the second drive wheel 20.
[0039] In a specific implementation, when the cleaning robot 100 is provided with two driving motors 40 respectively connected with the first driving wheel 20 and the second driving wheel 20, the two driving motors 40 can be directly connected to drive the first driving wheel 20 and the second driving wheel 20 to rotate, respectively. In the present example, the two driving motors 40 can be connected with the first driving wheel 20 and the second driving wheel 20 through a connecting rod transmission or a gear transmission.
[0040] Specifically, referring to Figure 3 , the center of the driving motor 40 transmission driving is eccentrically arranged with the center of the first driving wheel 20 and / or the second driving wheel 20 transmission connection, so that the bearing burden of the driving motor 40 can be reduced, and the stability of driving can be ensured.
[0041] In a specific implementation, the cleaning robot 100 can be provided with independent driving motors 40 for the first cleaning brush 31 and the second cleaning brush 32, respectively, to ensure efficient rotation cleaning of the first cleaning brush 31 and the second cleaning brush 32. In the present example, the two ends of the first cleaning brush 31 are respectively connected with at least one of the first driving wheel 20 and the second driving wheel 20, and the second cleaning brush 32 is connected with the first driving wheel 20 and / or the second driving wheel 20, so that the structure of the cleaning robot 100 can be simplified, and the production cost of the cleaning robot 100 can be reduced. At the same time, it is also beneficial to ensure the consistency of the rotation of the first cleaning brush 31, the second cleaning brush 32, the first driving wheel 20 and the second driving wheel 20, and to avoid interference between them.
[0042] It can be seen that, in the present example, the driving stability and reliability can be improved by connecting the driving motor 40 with the first driving wheel 20 or the second driving wheel 20, and the rotation consistency can be ensured by connecting the first cleaning brush 31 and the second cleaning brush 32 with the first driving wheel 20 and / or the second driving wheel 20, thereby improving the reliability of the cleaning robot 100.
[0043] In an example embodiment of the present application, one end of the first cleaning brush 31 is provided with a first gear 50, the first end of the second cleaning brush 32 is provided with a second gear 60, the first cleaning brush 31 is connected with the first driving wheel 20 and / or the second driving wheel 20 through the first gear 50, and the second cleaning brush 32 is connected with the first driving wheel 20 and / or the second driving wheel 20 through the second gear 60.
[0044] The first gear 50 can be arranged at one end of the first cleaning brush 31. At this time, the first cleaning brush 31 can be connected with the first driving wheel 20 or the second driving wheel 20 through the first gear 50. Alternatively, the first gear 50 can be arranged at opposite ends of the first cleaning brush 31. At this time, the first cleaning brush 31 is connected with the first driving wheel 20 and the second driving wheel 20.
[0045] For example, the first driving wheel 20 and / or the second driving wheel 20 can include a wheel body, a first transmission wheel and a second transmission wheel. The first transmission wheel and the second transmission wheel are respectively arranged on the opposite sides of the first driving wheel 20 and / or the second driving wheel 20, and the first transmission wheel is used for engaging with the first gear 50, and the second transmission wheel is used for engaging with the second gear 60.
[0046] Alternatively, referring to Figures 3 to 5 In an example embodiment of the present application, the first driving wheel 20 and the second driving wheel 20 each include a wheel body 21, and the wheel body 21 is respectively provided with a first accommodating cavity 21a and a second accommodating cavity 21b on the two sides. The inner wall of the first accommodating cavity 21a is provided with a first annular tooth 22, the inner wall of the second accommodating cavity 21b is provided with a second annular tooth 23, the first gear 50 is located in the first accommodating cavity 21a and engages with the first annular tooth 22, and the second gear 60 is located in the second accommodating cavity 21b and engages with the second annular tooth 23.
[0047] In a specific implementation, the end of the driving motor 40 can be provided with a driving gear, and the driving gear can be connected in transmission with the first driving wheel 20 or the second driving wheel 20 by engaging with the first annular tooth 22. Specifically, the driving motor 40 can drive the driving gear to rotate, thereby driving the first driving wheel 20 or the second driving wheel 20 to rotate through the first annular tooth 22. At the same time, when the first driving wheel 20 or the second driving wheel 20 rotates, the first gear 50 engaged with the first annular tooth 22 can be driven to rotate by the first annular tooth 22, so as to drive the first cleaning brush 31 to rotate through the first gear 50. When the first driving wheel 20 or the second driving wheel 20 rotates, the second gear 60 engaged with the second annular tooth 23 can also be driven to rotate by the second annular tooth 23, so as to drive the second cleaning brush 32 to rotate through the second gear 60.
[0048] It can be seen that, in the present example, the first accommodating cavity 21a and the second accommodating cavity 21b are respectively formed in the wheel body 21, and the first annular tooth 22 and the second annular tooth 23 are respectively constructed, so that the first cleaning brush 31 and the second cleaning brush 32 are respectively connected in transmission with the first driving wheel 20 and / or the second driving wheel 20 through the first gear 50 and the second gear 60 engaging with the first annular tooth 22 and the second annular tooth 23 respectively, which is conducive to simplifying the transmission connection, improving the convenience of assembling the cleaning robot 100 while ensuring the reliability of the transmission.
[0049] Referring to Figures 1 to 5In an example of the present application, the first cleaning brush 31 comprises a first rotating shaft 311 and a first brush 312, and the first gear 50 is sleeved on at least one end of the first rotating shaft 311. The second cleaning brush 32 comprises a second rotating shaft 321 and a second brush 322, and the second gear 60 is sleeved on the second rotating shaft 321. The extension line of the second rotating shaft 321 and the first rotating shaft 311 intersects at a point.
[0050] In a specific implementation, the first brush 312 is detachably sleeved on the first rotating shaft 311, so as to facilitate cleaning and replacement of the first brush 312. The second brush 322 is detachably sleeved on the second rotating shaft, so as to facilitate cleaning and replacement of the second brush 322.
[0051] In a specific implementation, the extension line of the second rotating shaft 321 and the first rotating shaft 311 intersects at a point, i.e., the first rotating shaft and the second rotating shaft are coaxially arranged. In this way, the cleaning progress of the first cleaning brush 31 and the second cleaning brush 32 can be kept consistent, and the cleaning effect can be optimized.
[0052] In a specific implementation, the first cleaning brush 31 can further comprise a support sleeve 313, which can be a hollow structure. The support sleeve 313 is sleeved on the first rotating shaft and is used to support the first brush 312. The support sleeve 313 can provide support for the first brush 312, so as to ensure that the radius of the first cleaning brush 31 is large enough, thereby avoiding the problem that the radius of the first brush 312 is too small to contact the bottom wall for cleaning or the cleaning effect is poor. Compared with directly arranging the first rotating shaft 311 as a structure with a large radius, this is conducive to the installation of the first gear 50 and can reduce the consumption of materials.
[0053] Specifically, the support sleeve 313 comprises a sleeve main body and an end mounting plate. The sleeve main body is a cylindrical structure constructed by a plurality of reinforcing ribs, so as to improve the structural strength of the support sleeve 313. The mounting plate can cover the end of the sleeve main body, so as to realize the connection and fixation of the support sleeve 313 and the first rotating shaft 311.
[0054] It can be seen that, in the present example, the extension line of the first rotating shaft 311 of the first cleaning brush 31 and the second rotating shaft 321 of the second cleaning brush 32 intersects at a point, so that the first rotating shaft 311 and the second rotating shaft 321 can be coaxially arranged, which is conducive to ensuring the consistency of the cleaning progress of the first cleaning brush 31 and the second cleaning brush 32 and optimizing the cleaning effect.
[0055] Referring to Figure 2 and Figure 3 In an example of the present application, the cleaning robot 100 further comprises a cover plate 70, the cover plate 70 is provided with a shaft seat 71, the second gear 60 is sleeved on one end of the second rotating shaft 321, and the other end of the second rotating shaft 321 is rotatably penetrated into the shaft seat 71 and connected with the second brush 322.
[0056] In specific implementation, the cleaning robot 100 comprises a mounting plate and a cover plate 70, which enclose a mounting space in which the first driving wheel 20 and / or the second driving wheel 20 is located. The shaft seat 71 is arranged on the outer side of the cover plate 70.
[0057] Specifically, referring to Figure 2 and Figure 3 , the shaft seat 71 comprises a bottom plate and a mounting cylinder. The bottom plate is used to be connected and fixed with the outer side of the cover plate 70, and the mounting cylinder is protruded on the side of the bottom plate away from the cover plate 70, and the second rotating shaft 321 is rotatably arranged in the mounting cylinder. The shaft seat 71 is used to limit the second rotating shaft 321, so as to ensure the stability of the connection of the second rotating shaft 321 and protect the second rotating shaft 321 from being broken due to the too large shaking amplitude of the second brush.
[0058] Specifically, the shaft seat 71 can further comprise a reinforcing rib, which is arranged around the circumferential side of the mounting cylinder and connected with the bottom plate. The reinforcing rib is used to strengthen the stability of the structure of the shaft seat 71.
[0059] It can be seen that in the present example, the second brush 322 can rotate synchronously with the second gear 60 through the second rotating shaft 321. By linking one end of the second rotating shaft 321 with the second gear 60, the other end is rotatably arranged in the shaft seat 71 and connected with the second brush 322, the protection of the second rotating shaft 321 can be realized, and the stability of the transmission connection between the second gear 60 and the second brush 322 is strengthened.
[0060] Referring to Figure 2 and Figure 3 , in an example embodiment of the present application, the second cleaning brush 32 further comprises a connecting cylinder 323, which is sleeved on the outer side of the shaft seat 71 and fixedly connected with the second rotating shaft 321, and the second brush 322 is sleeved on the outer circumferential side of the connecting cylinder 323 and detachably connected therewith.
[0061] The connecting cylinder 323 can be used to expand the radius of the second rotating shaft 321, so as to provide sufficient support for the second brush 322, and ensure that the radius of the second brush 322 is large enough to avoid affecting the cleaning effect due to the too small radius of the second brush 322. At the same time, compared with directly setting a larger radius for the second rotating shaft 321, the radius of the second rotating shaft 321 can be reduced by setting the connecting cylinder 323, which is beneficial to the connection between the second rotating shaft 321 and the second gear 60.
[0062] Specifically, the second brush 322 can be detachably connected with the connecting cylinder 323 through clamping or threaded connection and the like. Since the second cleaning brush 32 rotates constantly during work, it is preferred that the clamping mode is used to realize the detachable connection, so as to avoid the second brush 322 from falling off the connecting cylinder 323 during cleaning.
[0063] Specifically, the connecting cylinder 323 can be provided with a slot, and the second rotating shaft 321 can be inserted into the slot to be fixedly connected with the connecting cylinder 323 in a plug-in manner. Alternatively, one end of the second rotating shaft 321 and the connecting cylinder 323 can be provided with a limiting hole or a threaded hole, and the second cleaning brush 32 further comprises a limiting pin, one end of the limiting pin can be inserted into the limiting hole of the second rotating shaft 321 or screwed into the threaded hole of the second rotating shaft 321 through the connecting cylinder 323, and the other end of the limiting pin can be limited on the outer side of the bottom of the connecting cylinder 323, so that the second rotating shaft 321 and the connecting cylinder 323 are fixedly connected through the limiting pin.
[0064] It can be seen that, in the present example, the connecting cylinder 323 is provided to facilitate the support of the second brush 322, thereby ensuring the cleaning effect.

In this way, the first driven wheel 80 can be driven by the first driving wheel 20 to rotate synchronously, and the second driven wheel 80 can be driven by the second driving wheel 20 to rotate synchronously. By arranging the first driven wheel 80 and the second driven wheel 80, the use of the driving motor 40 can be reduced while ensuring the structural stability of the cleaning robot 100, the structure is simplified, and the utilization efficiency of the driving motor 40 is improved.
[0072] In a specific implementation, the second cleaning brush 32 can be arranged on the outer side of the first driving wheel 20 and the second driven wheel 80; or the cleaning brush can be arranged on the outer side of the second driving wheel 20 and the first driven wheel 80, so that no matter how the relative direction of the corner position of the intersection of the bottom wall and the side wall is, the corner position of the intersection of the bottom wall and the side wall can be cleaned by the second cleaning brush 32 on the outer side of the first driving wheel 20 or the cleaning brush on the outer side of the second driving wheel 20.
[0073] In a specific implementation, the second cleaning brush 32 can be arranged on the outer side of the first driving wheel 20, the second driving wheel 20, the first driven wheel 80, and the second driven wheel 80. At this time, the cleaning of the corner position of the intersection of the bottom wall and the side wall can be realized, and the two second cleaning brushes 32 on the same side can also be used for secondary cleaning, thereby optimizing the cleaning effect.
[0074] It can be understood that the second cleaning brush 32 can also be arranged on the outer side of the first driving wheel 20 and the first driven wheel 80; or the second cleaning brush 32 can also be arranged on the outer side of the second driving wheel 20 and the second driven wheel 80. This is not limited further.
[0075] It can be seen that in the present example, by configuring the first driven wheel 80 and the second driven wheel 80 for the cleaning robot 100, and arranging the second cleaning brush 32 on the outer side of the first driven wheel 80 and / or the second driven wheel 80, the flexibility of the second cleaning brush 32 configuration can be improved, and the cleaning effect can be optimized.

[0077] In a specific implementation, the two ends of the track 90 can be directly sleeved on the first driving wheel 20 and the first driven wheel 80 respectively, when the first driving wheel 20 is driven to rotate, the first driven wheel 80 can be driven to rotate through the track 90. Similarly, if the two ends of the track 90 are directly sleeved on the second driving wheel 20 and the second driven wheel 80, when the second driving wheel 20 is driven to rotate, the second driven wheel 80 can also be driven to rotate through the track 90. By driving the first driving wheel 20 or the second driving wheel 20 to rotate forward or reverse, the cleaning robot 100 can be controlled to move forward or backward.
[0078] Specifically, the outer surface of the first driving wheel 20 and the first driven wheel 80 is configured with a first outer gear ring, and the track 90 can be engaged with the first outer gear ring to drive the first driven wheel 80 and the first driving wheel 20 to rotate synchronously. Similarly, the outer surface of the second driving wheel 20 and the second driven wheel 80 is configured with a second outer gear ring, and the track 90 can be engaged with the second outer gear ring to drive the second driven wheel 80 and the second driving wheel 20 to rotate synchronously.
[0079] Specifically, the mounting plate and the cover plate 70 can be enclosed to form a mounting clamping groove, and the track 90 can be clamped in the mounting clamping groove. By clamping the track 90 in the mounting clamping groove, the stability of the track 90 installation can be improved.
[0080] As can be seen, in this example, by configuring the cleaning robot 100 with the track 90, the track type movement of the cleaning robot 100 can be achieved, and the obstacle crossing ability and climbing ability of the cleaning robot 100 can be improved.
