[0043] Referring to Figures 1 to 5 The present application provides a cleaning robot 100 comprising a cleaning body 10, a walking wheel set 20 arranged on both sides of the cleaning body 10 and rotatable relative to the cleaning body 10, and a cleaning mechanism 30 arranged on the front side of the walking wheel set 20 in the walking direction of the cleaning robot 100, the cleaning mechanism 30 being in driving connection with the walking wheel set 20 to be driven to rotate by the walking wheel set 20, and the maximum width of the cleaning mechanism 30 being greater than or equal to the maximum width of the walking wheel set 20 in the arrangement direction of the walking wheel set 20.

[0044] The cleaning body 10 has a front side and a rear side in the walking direction of the cleaning robot 100, and a left side and a right side perpendicular to the walking direction. The walking direction refers to the advancing direction of the cleaning robot 100. The arrangement direction of the walking wheel set 20 refers to the direction opposite to the left side and the right side.

[0045] The walking wheel set 20 is arranged on the left and right sides of the cleaning main body 10. Specifically, the walking wheel set 20 can include at least two pairs of sub-wheel sets 21, and each pair of sub-wheel sets 21 includes two rotating wheels 211 symmetrically arranged on the left and right sides of the cleaning main body 10. The shape, structure, material and size of the cleaning main body 10 are not limited in the present application. For example, the cleaning main body 10 can include but is not limited to a shell and a driving member arranged in the shell. The driving member can be a driving motor for driving the rotating wheels 211 to rotate to move the cleaning robot 100 as a whole.

[0046] Specifically, a single driving member can simultaneously drive the two rotating wheels 211 in a pair of sub-wheel sets 21 to rotate through a transmission shaft or the like to ensure consistency of the rotating speed; or a driving member can be configured for each of the two rotating wheels 211 in a pair of sub-wheel sets 21 to ensure stability and reliability of the driving. Specifically, the cleaning robot 100 can be configured with a driving member for each pair of sub-wheel sets 21 to ensure stability and reliability of the driving; or the cleaning robot 100 can be configured with a driving member for at least one pair of sub-wheel sets 21 to reduce production cost and structural complexity.

[0047] Referring to Figure 1 and Figure 2 In an embodiment of the present application, the walking wheel set 20 is a track-type walking wheel set 20. Specifically, the walking wheel set 20 can include an outer shell 22, a track 23 and at least two pairs of sub-wheel sets 21, wherein the rotating wheels 211 on one side of the cleaning main body 10 can be installed in the space enclosed by the outer shell 22, and the track 23 can be sleeved on the outer shell 22 and engaged with the rotating wheels 211 through the gap on the outer shell 22 to be driven to rotate synchronously when the rotating wheels 211 rotate, thereby moving the cleaning robot 100 as a whole. By setting the walking wheel set 20 as a track-type walking wheel set 20, the rotating wheels 211 can be better protected from damage due to exposure.

[0048] Specifically, the cleaning mechanism 30 is arranged on the front side of the walking wheel set 20 in the walking direction of the cleaning robot 100. By arranging the cleaning mechanism 30 on the front side of the walking wheel set 20 in the walking direction of the cleaning robot 100, the cleaning mechanism 30 can clean the dirt before the walking wheel set 20 advances to the dirty area, so as to avoid the walking wheel set 20 from being stained with dirt in the dirty area and affecting the cleaning effect in the subsequent cleaning process. It can be understood that a cleaning mechanism 30 can also be arranged on the rear side of the walking wheel set 20 in the walking direction of the cleaning robot 100 to perform secondary cleaning on the area passed by the cleaning robot 100, thereby improving the cleaning effect.

[0049] Specifically, the maximum width of the cleaning mechanism 30 refers to the distance from the leftmost side to the rightmost side of the cleaning mechanism 30, and the maximum width of the walking wheel set 20 refers to the distance from the leftmost side to the rightmost side of the walking wheel set 20. The maximum width of the cleaning mechanism 30 is greater than or equal to the maximum width of the walking wheel set 20, so that the cleaning width range of the cleaning mechanism 30 is greater than the maximum width of the walking wheel set 20, which is conducive to cleaning the area outside the walking wheel set 20.

[0050] The cleaning robot 100 provided by the utility model includes a cleaning main body 10, a walking wheel set 20 and a cleaning mechanism 30, the walking wheel set 20 is arranged on both sides of the cleaning main body 10 and can rotate relative to the cleaning main body 10, the cleaning mechanism 30 is arranged on the front side of the walking wheel set 20 in the walking direction of the cleaning robot 100, the cleaning mechanism 30 is in transmission connection with the walking wheel set 20 and is driven to rotate by the walking wheel set 20, and in the arrangement direction of the walking wheel set 20, the maximum width of the cleaning mechanism 30 is greater than or equal to the maximum width of the walking wheel set 20. The cleaning process of the cleaning robot 100 is that when the cleaning main body 10 drives the walking wheel set 20 to advance, the cleaning mechanism 30 located on the front side of the cleaning main body 10 can be driven to move, and the cleaning mechanism 30 can clean the pool wall of the swimming pool when the cleaning main body 10 advances. In the application, since the cleaning mechanism 30 is located on the front side of the cleaning main body 10, the cleaning mechanism 30 can clean the pool wall of the swimming pool by contacting the pool wall of the swimming pool when the cleaning main body 10 advances. In the application, since the maximum width of the cleaning mechanism 30 is greater than or equal to the maximum width of the walking wheel set 20, the cleaning mechanism 30 can not only clean the bottom area of the cleaning main body 10, but also clean the walking area of the walking wheel set 20 and the area outside the walking wheel set 20 during the movement of the cleaning robot 100, especially the corner of the swimming pool, and the cleaning robot 100 can also be driven to move along the edge of the swimming pool to clean the corner of the swimming pool by the cleaning mechanism 30, which is conducive to improving the cleaning effect of the swimming pool.

[0051] Referring to Figures 1 to 5 In an embodiment of the application, the cleaning mechanism 30 includes a cleaning roller brush 31 and a transmission assembly 32, the cleaning roller brush 31 is connected with the walking wheel set 20 through the transmission assembly 32 and rotates synchronously with the walking wheel set 20.

[0052] Specifically, the cleaning mechanism 30 can be provided with one or more cleaning roller brushes 31. For example, when the cleaning mechanism 30 is provided with only one cleaning roller brush 31, the length of the cleaning roller brush 31 is greater than the maximum width of the walking wheel set 20. At this time, the transmission mechanism is connected with the middle part of the cleaning roller brush 31 or the two ends of the cleaning roller brush 31 to ensure the stability of the cleaning roller brush 31.

[0053] Specifically, in the present example, two cleaning rollers 31 can be provided, and the two rollers can be connected to one of the rotating wheels 211 of the sub-wheel set 21 of the walking wheel set 20 through the transmission assembly 32. In this way, differential rotation of the two rotating wheels 211 can achieve differential steering of the cleaning robot 100.

[0054] Specifically, the transmission assembly 32 can be a linkage structure, a belt transmission structure 322, or a combination of a transmission shaft and a gear, etc. to connect the cleaning roller 31 and the walking wheel set 20 through a transmission connection, so that the cleaning roller 31 is in constant contact with the dirty area through rotation when the cleaning robot 100 is moving. The transmission assembly 32 can ensure the synchronization of the rotation of the cleaning roller 31 and the walking wheel set 20.

[0055] Referring to Figures 1 to 4 In an example embodiment of the present application, the cleaning roller 31 includes a first roller 311 and a second roller 312. The first roller 311 includes at least two rollers coaxially arranged, and the transmission assembly 32 is connected between the adjacent two first rollers 311 and drives the first rollers 311 to rotate synchronously with the walking wheel set 20. The second roller 312 is arranged at the rear side of the first roller 311 in the walking direction of the cleaning robot 100 and can cover the gap between any two first rollers 311.

[0056] The number of the first rollers 311 can be two, three or more, and the number of the second rollers 312 can be one, two or more, which can be set according to requirements.

[0057] Specifically, the at least two first rollers 311 can be sleeved on the same connecting shaft to achieve coaxial arrangement. At this time, the transmission assembly 32 can be connected to the middle part of the connecting shaft to achieve transmission connection and ensure the stability of the connecting shaft. Alternatively, the transmission assembly 32 can be connected between the at least two adjacent first rollers 311 to achieve transmission connection while ensuring the stability of the connecting shaft.

[0058] Alternatively, specifically, the at least two first rollers 311 can be sleeved on different connecting shafts, and these connecting shafts can be independently connected to the transmission assembly 32. Alternatively, these connecting shafts can be spliced into one connecting shaft to be connected to the transmission structure 322 through the above-mentioned only one connecting shaft.

[0059] Specifically, the second rolling brush 312 can be connected with the walking wheel set 20 through the transmission structure 322, so as to rotate synchronously with the walking wheel set 20. The second rolling brush 312 is located at the rear side of the first rolling brush 311 and can cover the gap between any two first rolling brushes 311, so as to avoid interference with the first rolling brush 311 and clean the gap that cannot be cleaned by the first rolling brush 311 along with the movement of the cleaning robot 100.

[0060] In the present example, by setting the cleaning rolling brush 31 as the first rolling brush 311 and the second rolling brush 312 and making the second rolling brush 312 cover the gap between any two first rolling brushes 311, not only the convenience of assembly of the rolling brush can be ensured, but also the cleaning effect can be improved and omission during cleaning can be avoided.

[0061] In an example embodiment of the present application, when the first rolling brush 311 is provided with a plurality of first rolling brushes 311, the second rolling brush 312 can be provided with one second rolling brush 312, and the length of the second rolling brush 312 is greater than or equal to the interval distance between the two farthest first rolling brushes 311.

[0062] Specifically, since all the first rolling brushes 311 are coaxially arranged, the two farthest first rolling brushes 311 refer to the leftmost first rolling brush 311 and the rightmost first rolling brush 311. When the length of the second rolling brush 312 is greater than or equal to the interval distance between the two farthest first rolling brushes 311, the second rolling brush 312 can not only cover the gap between any two first rolling brushes 311, but also cover all the first rolling brushes 311 between the leftmost first rolling brush 311 and the rightmost first rolling brush 311.

[0063] For example, if the number of first rolling brushes 311 is four, the length of the second rolling brush 312 should be greater than or equal to the interval distance between the leftmost first rolling brush 311 and the rightmost first rolling brush 311, and at this time the second rolling brush 312 can cover the gap between the middle two rolling brushes and any two rolling brushes.

[0064] It can be seen that in the present example, by providing the second rolling brush 312 with one, the structure can be simplified and the convenience of assembly of the second rolling brush 312 can be improved.

[0065] In an example embodiment of the present application, when the first rolling brush 311 is provided with a plurality of first rolling brushes 311, the difference between the number of first rolling brushes 311 and the number of second rolling brushes 312 is one, one second rolling brush 312 is arranged between every two adjacent first rolling brushes 311, and the length of the second rolling brush 312 is greater than or equal to the interval distance between the two adjacent first rolling brushes 311.

[0066] Specifically, the difference between the number of the first rolling brushes 311 and the number of the second rolling brushes 312 is one, which means that if the number of the first rolling brushes 311 is M, the number of the second rolling brushes 312 can be M-1, where M is a positive integer greater than or equal to 2. At this time, one second rolling brush 312 can be configured for the gap between every two adjacent first rolling brushes 311, and the length of the second rolling brush 312 is greater than or equal to the distance between the two first rolling brushes 311, so as to ensure that the second rolling brush 312 covers the gap between any two first rolling brushes 311.

[0067] Specifically, when the number of the second rolling brushes 312 is multiple, the multiple second rolling brushes 312 can be coaxially arranged or non-coaxially arranged, which is not limited here.

[0068] For example, referring to Figures 1 to 4 , if the number of the first rolling brushes 311 is two, the number of the second rolling brushes 312 is one, and the length of the second rolling brush 312 is greater than or equal to the distance between the two first rolling brushes 311, so as to cover the gap between the two first rolling brushes 311.

[0069] It can be seen that in the present example, multiple second rolling brushes 312 are arranged to cover the gap between any two first rolling brushes 311.

[0070] Referring to Figure 2 and Figure 5 , in an example embodiment of the present application, the transmission assembly 32 includes a first rotating shaft 321, a transmission structure 322, and a second rotating shaft 323. The first rolling brush 311 is sleeved on the first rotating shaft 321. The transmission structure 322 is located between the opposite sides of the sub-wheel set 21 in the extension direction of the cleaning rolling brush 31, and is connected with the sub-wheel set 21. The first rotating shaft 321 is in transmission connection with the transmission structure 322, and is driven by the transmission structure 322 to rotate synchronously with the sub-wheel set 21. The second rotating shaft 323 is located between the opposite sides of the sub-wheel set 21 in the extension direction of the cleaning rolling brush 31. The two ends of the second rotating shaft 323 are respectively connected with one of the rotating wheels 211 in the sub-wheel set 21, and are driven by the sub-wheel set 21 to rotate synchronously. The second rolling brush 312 is sleeved on the second rotating shaft 323. The first rotating shaft 321 and the second rotating shaft 323 are arranged in a spaced manner.

[0071] The first rotating shaft 321 is the connecting shaft as described above. The extension direction of the cleaning rolling brush 31 is the opposite direction between the left side and the right side.

[0072] Specifically, at least two first rolling brushes 311 can be sleeved on the first rotating shaft 321, and the transmission structure 322 can be connected with the first rotating shaft 321.

[0073] Specifically, the transmission structure 322 and the second rotating shaft 323 can be respectively connected with the sub wheel set 21 through gear transmission or magnetic transmission, etc. For example, the rotating wheel 211 can be a driving wheel, and the end of the transmission structure 322 and the second rotating shaft 323 connected with the rotating wheel 211 can be provided with a driven wheel, and the synchronous rotation of the first rotating shaft 321 and the second rotating shaft 323 with the sub wheel set 21 can be realized through the meshing of the driving wheel and the driven wheel. For example, the driving wheel can be provided with an inner gear ring, and the driven wheel can be provided with an outer gear ring, and the outer gear ring of the driven wheel can be meshed with the inner gear ring of the driving wheel.

[0074] Specifically, the transmission structure 322 and the second rotating shaft 323 can be connected with the same sub wheel set 21, or can be connected with different sub wheel sets 21. In order to simplify the volume of the transmission structure 322, the transmission structure 322 can be connected with the sub wheel set 21 close to the front side of the cleaning main body 10. In order to optimize the cleaning effect, the second rotating shaft 323 can also be connected with the sub wheel set 21 close to the front side of the cleaning main body 10. Connecting the transmission structure 322 and the second rotating shaft 323 to the same sub wheel set 21 can also improve the consistency of the rotation of the first rotating shaft 321 and the second rotating shaft 323.

[0075] In the present example, the two ends of the second rotating shaft 323 and the left and right sides of the transmission structure 322 can be respectively connected with one rotating wheel 211 in the sub wheel set 21, so as to ensure that when the sub wheel set 21 is driven to rotate, the second rotating shaft 323 can be driven to rotate, and the first rotating shaft 321 can be driven to rotate through the transmission structure 322, so that the first rolling brush 311 and the second rolling brush 312 can follow the first rotating shaft 321 and the second rotating shaft 323 to rotate synchronously. By connecting the two ends of the second rotating shaft 323 and the left and right sides of the transmission structure 322 with one rotating wheel 211 in the sub wheel set 21 respectively, the stability of the connection between the first rotating shaft 321 and the second rotating shaft 323 can be improved, and the stability of the rotation cleaning of the first rolling brush 311 and the second rolling brush 312 can be improved.

[0076] Specifically, the ground clearance of the first rotating shaft 321 and the ground clearance of the second rotating shaft 323 can be set to be the same, so as to ensure the consistency of the cleaning effect of the first rolling brush 311 and the second rolling brush 312.

[0077] It can be seen that in the present example, by connecting the first rolling brush 311 and the second rolling brush 312 with the sub wheel set 21 through the first rotating shaft 321 and the second rotating shaft 323 respectively, and spacing the first rotating shaft 321 and the second rotating shaft 323, the mutual interference of the first rolling brush 311 and the second rolling brush 312 during cleaning work can be avoided.

[0078] Referring to Figure 3 and Figure 5In an example of the present application, the transmission structure 322 comprises a third rotating shaft 301, a mounting frame 302, and a gear set. The third rotating shaft 301 is located between the opposite sides of the sub-wheel set 21 in the extension direction of the cleaning roller brush 31. The two ends of the third rotating shaft 301 are respectively connected with one of the sub-wheel sets 21, so as to be driven to rotate synchronously by the sub-wheel set 21. The mounting frame 302 is connected with the cleaning main body 10. The first rotating shaft 321 and the third rotating shaft 301 are arranged in parallel and penetrate through the mounting frame 302. The gear set is arranged in the mounting frame 302. The first rotating shaft 321 and the third rotating shaft 301 are connected by the gear set.

[0079] The third rotating shaft 301 is used to be connected with the two rotating wheels 211 of the sub-wheel set 21, so as to rotate synchronously with the sub-wheel set 21 when the two rotating wheels 211 of the sub-wheel set 21 are driven to rotate.

[0080] Specifically, when the walking wheel set 20 is a track type walking wheel set 20, the third rotating shaft 301 and the second rotating shaft 323 can penetrate through the shell 22 of the walking wheel set 20 and be connected with the rotating wheels 211 inside, so as to realize the connection with the rotating wheels 211.

[0081] Specifically, the mounting frame 302 is used to mount and fix the gear set. By connecting the mounting frame 302 with the cleaning main body 10, the stability of the mounting frame 302 can be ensured, and the mounting frame 302 can be prevented from being affected by the rotation of the walking wheel set 20.

[0082] Specifically, by arranging the first rotating shaft 321 and the third rotating shaft 301 in parallel and penetrating through the mounting frame 302, the first rotating shaft 321 and the third rotating shaft 301 can be prevented from interfering with each other, and the reliability of the cleaning mechanism 30 structure can be improved.

[0083] Specifically, the ground clearance of the third rotating shaft 301 can be set to be higher than the ground clearance of the first rotating shaft 321, so as to avoid the interference of the third rotating shaft 301 with the cleaning and rolling of the first roller brush 311.

[0084] Specifically, the gear set includes at least two gears, each of which can be of the same size or different sizes. When the gear set includes two gears, the two gears can be respectively sleeved on the first rotating shaft 321 and the third rotating shaft 301 and can be directly engaged. In this way, when the third rotating shaft 301 rotates with the rotating wheel 211, the first rotating shaft 321 can be driven to rotate synchronously by the engaged gears. When the gear set includes multiple gears, two of the multiple gears can be respectively sleeved on the first rotating shaft 321 and the third rotating shaft 301, and the remaining gears can be sequentially engaged, and the gears engaged with the first rotating shaft 321 and the gears engaged with the third rotating shaft 301 can be respectively engaged with the two gears at the ends. In this way, when the third rotating shaft 301 rotates with the rotating wheel 211, the first rotating shaft 321 can be driven to rotate by the multiple engaged gears in sequence. By providing the gear set with multiple gears, the distance between the first rotating shaft 321 and the second rotating shaft 323 can be increased, thereby increasing the distance between the first rolling brush 311 and the walking wheel set 20, avoiding interference between the first rolling brush 311 and the walking wheel set 20, and ensuring the stability of the cleaning mechanism 30.

[0085] Referring to Figure 3 and Figure 5 In an example embodiment of the present application, the gear set 303 includes a first gear 3031, a second gear 3032, and a third gear 3033. The first gear 3031 is arranged in the mounting frame 302 and is sleeved on the third rotating shaft 301 to rotate synchronously with the third rotating shaft 301. The second gear 3032 is arranged in the mounting frame 302 and is sleeved on the first rotating shaft 321 to rotate synchronously with the first rotating shaft 321. The third gear 3033 is arranged in the mounting frame 302 and is engaged with the first gear 3031 and the second gear 3032 to drive the first gear 3031 and the second gear 3032.

[0086] Specifically, when the third rotating wheel 211 rotates with the sub-wheel set 21, the first gear 3031 can drive the second gear 3032 engaged therewith to rotate, and the second gear 3032 can drive the third gear 3033 engaged therewith to rotate, thereby realizing the rotation of the first rotating shaft 321 connected with the third gear 3033 and the rotation of the first rolling brush 311 for cleaning. By providing the gear set 303 with the first gear 3031, the second gear 3032, and the third gear 3033, not only can the distance between the first rolling brush 311 and the walking wheel set 20 be increased to avoid interference between the first rolling brush 311 and the walking wheel set 20, but also the stability of the gear set 303 can be ensured, and the transmission effect can be optimized.

[0087] It can be seen that, in the present example, the transmission structure 322 is arranged as the third rotating shaft 301, the mounting frame 302 and the gear set 303, so that the first rotating shaft 321 and the sub-wheel set 21 are drivingly connected, and the first rolling brush 311 can rotate to realize cleaning.

[0088] Referring to Figure 3 and Figure 5 In an example embodiment of the present application, the mounting frame 302 comprises a mounting body 3021 and a cover plate 3022, the mounting body 3021 is connected with the cleaning body 10, and the mounting body 3021 is formed with at least one opening in the extending direction of the cleaning rolling brush 31; the cover plate 3022 covers the opening and forms an installation space together with the mounting body 3021, the gear set 303 is arranged in the installation space and can rotate relative to the mounting body 3021, and the first rotating shaft 321 and the third rotating shaft 301 are arranged through the cover plate 3022 respectively.

[0089] The material of the mounting frame 302 is not limited and can be set according to requirements, for example, the material of the mounting frame 302 can be plastic.

[0090] Specifically, the mounting body 3021 can be an open structure on at least one side in the extending direction of the cleaning rolling brush 31, so as to facilitate the assembly and disassembly of the gear set 303. When the left and right sides of the mounting body 3021 are respectively provided with one opening, the cover plate 3022 is provided with two cover plates 3022, and the two cover plates 3022 cover one opening respectively to form an installation space. The cover plate 3022 and the mounting body 3021 can be detachably connected by clamping, threaded connection or the like, so as to facilitate the maintenance, assembly and disassembly of the gear set 303.

[0091] Specifically, the shape of the mounting body 3021 can be designed to fit the gear set 303 while ensuring that the gears in the gear set 303 can rotate, so as to limit the positions of the gears when the sizes of the gears in the gear set 303 are different, and to avoid large fluctuations of the gears.

[0092] Specifically, the mounting body 3021 can further be provided with a partition plate to divide the installation space into two subspaces, and one gear set 303 can be assembled in each of the two subspaces. Alternatively, the mounting body 3021 can be provided with an axial surrounding isolation rib towards the inner side of the installation space, and the isolation rib can divide the installation space into two sub-regions, and one gear set 303 can be assembled in each of the two sub-regions.

[0093] Further, when the gear set 303 is provided with two gear sets, the third rotating shaft 301 and the first rotating shaft 321 can be connected through the two gear sets 303 at the same time, so as to improve the stability of the transmission of the transmission structure 322.

[0094] Alternatively, further, when the gear set 303 is provided with two, the first rotating shaft 321 can include two first shaft segments, and the third rotating shaft 301 includes two second shaft segments. The two first shaft segments are respectively connected with one gear set 303, one end of the two second shaft segments is respectively connected with one of the two rotating wheels 211 of the sub-wheel set 21, the other end is respectively connected with one gear set 303, and at least one first rolling brush 311 is sleeved on each first shaft segment. In this way, when the cleaning robot 100 realizes steering by differential speed of the left and right rotating wheels 211, the differential speed of the two rotating wheels 211 can not be interfered by the cleaning mechanism 30.

[0095] It can be seen that in the present example, the gear set 303 can be isolated from the outside by assembling the gear set 303 in the mounting space formed by the mounting frame 302, thereby achieving protection of the gear set 303.

It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
