[0041] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0042] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present application are only used to explain the relative positional relationship, movement condition, etc. between components in a certain posture, and if the certain posture changes, the directional indications also change accordingly.

[0043] It is also needed to state that when an element is referred to as being "fixed" or "set" on another element, it can be directly on the other element or a middle element can exist at the same time. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or indirectly connected to the other element through a middle element.

[0044] In addition, the description involving "first", "second" and the like in the present application is only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second" can explicitly or implicitly include at least one of the features. In addition, the technical solutions of various embodiments can be combined with each other, but it must be based on the fact that a person skilled in the art can realize it, and when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, nor is it within the protection scope required by the present application.

[0045] The pool cleaning robot usually adopts a crawler driving mode when performing cleaning operation. The crawler moves by contacting with the ground, so as to realize the movement and cleaning of the cleaning robot in the pool. However, in the existing pool cleaning robot, when the bottom crawler contacts with the ground during cleaning, stones, debris, sand and other sundries are easily adhered. These sundries will be rotated to the upper position with the crawler during the advancing process of the crawler, and part of the sundries can enter the side of the main body, especially the cavity area of the crawler wheel, especially during long-term use, which can cause accumulation of sundries and affect the normal work of the crawler wheel and related components, reduce the service life and cleaning efficiency of the pool robot.

[0046] Therefore, the cleaning robot provided by the embodiments of the present application can effectively prevent sundries from entering the mounting cavity, thereby avoiding the influence of sundries on the normal work of the crawler wheel and related components, reducing the wear of the crawler wheel and related components, prolonging the service life of the cleaning robot as a whole, and improving the working efficiency and stability of the cleaning robot.

[0047] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. In the case of no conflict, the embodiments described below and the features in the embodiments can be combined with each other.

[0048] As shown in Figures 1 to 7 The cleaning robot provided by the embodiments of the present application includes a bottom shell 10, a wheel cover 20, two crawler wheels 30 and a crawler 40.

[0049] The side of the bottom shell 10 is provided with a side shell 11. The wheel cover 20 and the side shell 11 enclose to form a mounting cavity 10a. Two track wheels 30 are mounted in the mounting cavity 10a, and a track 40 is sleeved on the two track wheels 30. The track 40 is provided with a first protruding portion 41 extending towards the side shell 11, and the side shell 11 is provided with a second protruding portion 111 extending towards the wheel cover 20. The projection of the first protruding portion 41 and the second protruding portion 111 in the vertical direction at least partially overlaps, and there is a first preset gap 411 between the two. The first protruding portion 41 is located on the side of the second protruding portion 111 away from the mounting cavity 10a.

[0050] The gap between the side shell 11 and the wheel cover 20 allows the track 40 to pass through the gap, be sleeved on the two track wheels 30, and be in driving connection with the two track wheels 30. The track 40 can also extend out of the surface of the side shell 11 and the wheel cover 20 to contact the ground, realizing the movement of the cleaning robot.

[0051] The gap between the existing track 40 and the side shell 11 is generally arranged in the direction from the inside to the outside of the mounting cavity 10a. In this way, debris is easily pressed into the mounting cavity 10a from the bottom and easily falls into the mounting cavity 10a from the top. In the present application, by arranging the projection of the first protruding portion 41 and the second protruding portion 111 in the vertical direction to at least partially overlap and have a first preset gap 411 therebetween, on the basis of avoiding the interference of the side shell 11 with the movement of the track 40, the extension direction of the first preset gap 411 between the side shell 11 and the track 40 and the vertical direction have an included angle, for example, perpendicular to the vertical direction. In this way, debris is neither easily pressed into the mounting cavity 10a from the bottom nor easily falls into the mounting cavity 10a from the top.

[0052] The cleaning robot of the present application can make the extension direction of the first preset gap 411 and the vertical direction have an included angle through the arrangement of the first protruding portion 41 and the second protruding portion. During the movement of the cleaning robot for cleaning, debris above the track 40 is not easy to fall into the mounting cavity 10a along the first preset gap 411. Moreover, debris below the track 40 is also not easy to be pressed into the mounting cavity 10a along the first preset gap 411. Therefore, the cleaning robot of the present application can effectively prevent debris from entering the mounting cavity 10a, thereby avoiding the influence of debris on the normal work of the track wheel 30 and its related components, reducing the wear of the track wheel 30 and its related components, prolonging the service life of the overall cleaning robot, and improving the working efficiency and stability of the cleaning robot.

[0053] In some embodiments, a transmission assembly is also installed in the installation cavity 10a to drive the track wheels 30 and / or other mechanical structures to move. In this way, the structure of the present application can also avoid the influence of sundries on the normal operation of the transmission assembly, reduce the wear of the transmission assembly, and thus ensure the normal operation of the track wheels 30 and related components driven by the transmission structure.

[0054] As shown in Figure 9 some embodiments, the second protruding part 111 includes two first linear segments 1111 and two first arc-shaped segments 1112, the two first arc-shaped segments 1112 are arranged at two ends of the side shell 11 in the moving direction of the cleaning robot, and the two first linear segments 1111 are arranged between and correspond to the two first arc-shaped segments 1112, and the two first linear segments 1111 and the two first arc-shaped segments 1112 form a ring-shaped second protruding part 111. In this way, the first protruding part 41 can be overlaid on the second protruding part 111 at each position of the track 40 as a whole. During the movement of the cleaning robot, the sundries above the track 40 are not easy to fall into the installation cavity 10a along the first preset gap 411 between the first linear segment 1111 above and the first protruding part 41, the sundries below the track 40 are not easy to be pressed into the installation cavity 10a along the first preset gap 411 between the first linear segment 1111 below and the first protruding part 41, and the sundries on the front side and the rear side of the track 40 are not easy to enter the installation cavity 10a along the first preset gap 411 between the two first arc-shaped segments 1112 and the first protruding part 41. Thus, the sundries can be blocked from entering the installation cavity 10a in all directions, and the normal operation of the structure in the installation cavity 10a is ensured.

[0055] As shown in Figure 8 and Figure 9 some embodiments, the two track wheels 30 are respectively installed at the two first arc-shaped segments 1112. By arranging the two track wheels 30 at the two first arc-shaped segments 1112, effective support of the track 40 as a whole can be achieved, and the cleaning robot can be stably driven to move when the track 40 moves. Moreover, under the blockage of the track wheels 30, the sundries are also less likely to enter the installation cavity 10a from the front side and the rear side of the track 40, and thus the structure inside the installation cavity 10a can be further protected.

[0056] As shown in Figure 3 , Figure 4 , Figure 6 and Figure 7As shown in some embodiments, the first preset gap 411 in the vertical direction between the first protruding portion 41 and the second protruding portion 111 is 0.5-1.5 mm. It should be noted that if the first preset gap 411 between the first protruding portion 41 and the second protruding portion 111 is too small, the second protruding portion 111 can interfere with the movement of the track 40, and when the second protruding portion 111 is provided with a drainage structure, it can also hinder drainage. If the first preset gap 411 between the first protruding portion 41 and the second protruding portion 111 is too large, debris can easily enter the mounting cavity 10a from between the first protruding portion 41 and the second protruding portion 111. Therefore, in the present embodiment, by limiting the first preset gap 411 between the first protruding portion 41 and the second protruding portion 111, the stable movement of the track 40 can be ensured, and debris can be prevented from entering the mounting cavity 10a.

[0057] As shown in some embodiments, Figure 3 , Figure 4 , Figure 6 and Figure 7 , in some embodiments, the track 40 includes a track body 43, the first protruding portion 41 is arranged on one side of the track body 43 close to the side shell, and the track body 43 extends towards the mounting cavity 10a and is arranged spaced apart from the second protruding portion 111 in the direction from the side shell 11 to the wheel cover 20. In combination with the structure of the first protruding portion 41 described above, the gap between the track 40 and the side shell 11 can have an L-shaped structure. If debris wants to enter the mounting cavity 10a, it needs to first enter the first preset gap 411 between the first protruding portion 41 and the second protruding portion 111, and then pass through the gap between the track body and the second protruding portion 111. Therefore, such a structure can make it more difficult for debris to enter the mounting cavity 10a, ensuring the normal operation of the structures in the mounting cavity 10a. Furthermore, the part of the track body 43 extending towards the mounting cavity 10a can also be drivingly connected to the track wheel 30, so as to realize stable driving of the track wheel 30 to move the track 40.

[0058] Exemplarily, the distance between the track body 43 and the second protruding portion 111 is 0.5-1.5 mm. By limiting this distance, the stable movement of the track 40 can be ensured, and debris can be prevented from entering the mounting cavity 10a.

[0059] In further embodiments, the part of the second protruding portion 111 outside the first protruding portion 41 is provided with a groove. Here, the part of the second protruding portion 111 outside the first protruding portion 41 refers to the part of the second protruding portion 111 whose projection in the vertical direction does not coincide with the first protruding portion 41. By providing the groove, debris outside the track 40 can more easily enter the groove, and it is not easy to enter the mounting cavity 10a along the first preset gap 411 between the second protruding portion 111 and the first protruding portion 41.

[0060] Exemplarily, the groove is an arc-shaped groove. In this way, it is not easy for sundries to enter the mounting cavity 10a along the first preset gap 411 between the second protruding portion 111 and the first protruding portion 41, and it is also possible to avoid sundries from being stranded in the groove and affecting the movement of the cleaning robot.

[0061] As Figures 1 to 7 shown, in some embodiments, the track 40 is provided with a third protruding portion 42 extending towards the wheel cover 20, the wheel cover 20 is provided with a fourth protruding portion 21 extending towards the side shell 11, the projections of the third protruding portion 42 and the fourth protruding portion 21 in the vertical direction at least partially coincide and have a second preset gap 421 therebetween, and the third protruding portion 42 is located on the side of the second protruding portion 111 away from the mounting cavity 10a.

[0062] The gap between the existing track 40 and the wheel cover 20 is generally arranged in the direction extending from the inside to the outside of the mounting cavity 10a, so that sundries are easy to be pressed into the mounting cavity 10a from the bottom and easy to fall into the mounting cavity 10a from the top. In the present application, by arranging the projections of the third protruding portion 42 and the fourth protruding portion 21 in the vertical direction to at least partially coincide and have a second preset gap 421 therebetween, on the basis of avoiding the movement of the wheel cover 20 interfering with the movement of the track 40, the extending direction of the second preset gap 421 between the wheel cover 20 and the track 40 into the mounting cavity 10a and the vertical direction have an included angle, for example, it can be perpendicular to the vertical direction. In this way, sundries are not easy to be pressed into the mounting cavity 10a from the bottom, nor easy to fall into the mounting cavity 10a from the top. Therefore, in the present embodiment, it is further possible to avoid sundries entering the mounting cavity 10a from the top or the bottom through the track 40 and the wheel cover 20, thereby avoiding the sundries affecting the normal work of the track wheel 30 and its related components, reducing the wear of the track wheel 30 and its related components, prolonging the service life of the whole cleaning robot, and improving the working efficiency and stability of the cleaning robot.

[0063] As Figure 10As shown in some embodiments, the fourth protruding portion 21 comprises two second linear segments 211 and two second arc-shaped segments 212, the two second arc-shaped segments 212 are arranged at the two ends of the wheel cover 20 and are spaced apart in the direction of movement of the cleaning robot, the two second linear segments 211 are located between the two second arc-shaped segments 212 and are correspondingly connected, and the two second linear segments 211 and the two second arc-shaped segments 212 enclose the annular fourth protruding portion 21. In this way, the third protruding portion 42 can be overlaid on the fourth protruding portion 21 at each position of the wheel cover 20 as a whole. During the movement of the cleaning robot, the debris above the track 40 is not easy to fall into the mounting cavity 10a along the second preset gap 421 between the second linear segment 211 above and the third protruding portion 42, the debris below the track 40 is not easy to be pressed into the mounting cavity 10a along the second preset gap 421 between the second linear segment 211 below and the third protruding portion 42, and the debris on the front side and the rear side of the track 40 is not easy to enter the mounting cavity 10a along the second preset gap 421 between the two second arc-shaped segments 212 and the third protruding portion 42. Thus, the debris can be prevented from entering the mounting cavity 10a in all directions, and the normal work of the structure in the mounting cavity 10a is ensured.

[0064] As shown in some embodiments, Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown in some embodiments, the second preset gap 421 between the third protruding portion 42 and the fourth protruding portion 21 in the vertical direction is 0.5-1.5 mm. It should be noted that if the second preset gap between the third protruding portion 42 and the fourth protruding portion 21 is too small, the fourth protruding portion 21 can interfere with the movement of the track 40, and when the fourth protruding portion 21 is provided with a drainage structure, it can also hinder the drainage. If the second preset gap between the third protruding portion 42 and the fourth protruding portion 21 is too large, the debris is easy to enter the mounting cavity 10a from between the third protruding portion 42 and the fourth protruding portion 21. Therefore, in the present embodiment, by limiting the second preset gap 421 between the third protruding portion 42 and the fourth protruding portion 21, the stable movement of the track 40 can be ensured, and the debris can be prevented from entering the mounting cavity 10a.

[0065] As shown in some embodiments, Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, in some embodiments, the track 40 comprises a track body 43, the third protrusion 42 is arranged on one side of the track body 43 close to the wheel cover 20, the track body 43 extends towards the mounting cavity 10a, and is arranged apart from the fourth protrusion 21 along the direction from the side shell 11 to the wheel cover 20. In combination with the structure of the third protrusion 42, the gap between the track 40 and the wheel cover 20 can be in an L-shaped structure, and if the sundries want to enter the mounting cavity 10a, they need to first enter the second preset gap 421 between the third protrusion 42 and the fourth protrusion 21, and then pass through the gap between the track body 43 and the fourth protrusion 21. Therefore, such a structure can make it more difficult for sundries to enter the mounting cavity 10a, and ensure the normal work of the structure in the mounting cavity 10a. In addition, the part of the track body 43 extending towards the mounting cavity 10a can also be in driving connection with the track wheel 30, so as to realize stable driving of the track wheel 30 to move the track 40.

[0066] Exemplarily, the distance between the track body and the fourth protrusion 21 is 0.5-1.5mm. By limiting this distance, the stable movement of the track 40 can be ensured, and the sundries can be prevented from entering the mounting cavity 10a.

[0067] In further embodiments, at least the part of the fourth protrusion 21 outside the third protrusion 42 is arranged inclined towards the center of the wheel cover 20 along the direction from the side shell 11 to the wheel cover 20. Here, the part of the fourth protrusion 21 outside the third protrusion 42 refers to the part whose vertical projection does not coincide with the third protrusion 42. By arranging this part inclined, the sundries can be prevented from being retained in the fourth protrusion 21, so that the sundries can slide off the wheel cover 20 along the inclined part of the fourth protrusion 21, further preventing the sundries from entering the mounting cavity 10a from between the track 40 and the wheel cover 20, and ensuring the normal work of the structure in the mounting cavity 10a.

[0068] As Figure 1 and Figure 2 and Figure 4 and Figure 7As shown, in the embodiment of the present application, the side shell 11 is provided with a second protruding portion 111 extending towards the wheel cover 20 at least at the bottom, the projection of the first protruding portion 41 and the second protruding portion 111 in the vertical direction at least partially overlaps and has a first preset gap 411 therebetween, and the first protruding portion 41 is located on the side of the second protruding portion 111 away from the mounting cavity 10a. Moreover, the wheel cover 20 is provided with a fourth protruding portion 21 extending towards the side shell 11 at least at the bottom, the projection of the third protruding portion 42 and the fourth protruding portion 21 in the vertical direction at least partially overlaps and has a second preset gap 421 therebetween, and the third protruding portion 42 is located on the side of the second protruding portion 111 away from the mounting cavity 10a. When the cleaning robot moves for cleaning, the track of the cleaning robot will be in contact with the ground, and if an obstacle or uneven ground is encountered, the local part of the track 40 is prone to deformation. Such deformation will result in insufficient contact between the track and the ground, thereby affecting the stability of the movement of the cleaning robot and the cleaning effect. In the present application, at the bottom of the cleaning robot, the first protruding portion 41 is located below the second protruding portion 111, and the third protruding portion 42 is located below the fourth protruding portion 21. When the track 40 is in contact with the ground, the second protruding portion 111 and the fourth protruding portion 21 can support the two sides of the track 40 respectively, so that the track 40 can maintain a good shape during movement, avoiding the deformation or collapse of the track 40 when it encounters obstacles or uneven surfaces during movement, thereby enhancing the overall structural stability of the track 40. Specifically, the support of the second protruding portion 111 to the first protruding portion 41 can avoid the inward collapse of the track 40 on one side of the side shell 11, which would cause the side shell 11 to lift off the ground and rub against it. The support of the fourth protruding portion 21 to the third protruding portion 42 can avoid the inward collapse of the track 40 on one side of the wheel cover 20, which would cause the wheel cover 20 to lift off the ground and rub against it. Therefore, the stability of the movement of the cleaning robot and the cleaning effect can be ensured.

[0069] Moreover, through such support design, the problem of insufficient grip, slipping or jamming of the track 40 due to deformation during long-term use is effectively prevented, so that the track 40 can always maintain a relatively stable contact state with the ground, effectively enhancing the grip of the track wheel 30, thereby improving the movement stability and cleaning effect of the cleaning robot in various environments. For example, the cleaning robot can still efficiently perform cleaning tasks in complex terrain, obstacles or a pool with many debris at the bottom.

[0070] Furthermore, through such support design, the service life of the track 40 is also prolonged. Since the track 40 is not prone to deformation during use, the wear of the track wheel 30 and its related components is effectively reduced, which not only reduces the maintenance cost, but also improves the overall reliability and durability of the cleaning robot.

[0071] Therefore, the design can effectively improve the cleaning efficiency, stability and durability of the cleaning robot, and meet the needs of the cleaning robot for high efficiency, stability and durability.

[0072] In some embodiments, the side shell 11 or the wheel cover 20 is provided with a support block in the mounting cavity 10a, which is located between the track wheels 30 and close to the bottom of the track 40, for example, the support block is located between the two track wheels 30 and close to the bottom of the track 40. It should be noted that the bottom of the track 40 itself can be supported by the track wheel 30, and the part of the track 40 between the track wheels 30 is hollow. In this embodiment, the hollow part of the bottom of the track 40 can be supported by the support block provided, so as to stably support the bottom of the track 40. Therefore, the track 40 can further maintain good shape during movement, avoiding the deformation or collapse of the track 40 when encountering obstacles or uneven surfaces during movement, thereby enhancing the overall structural stability of the track 40 and ensuring the stability of the cleaning robot movement and cleaning effect.

[0073] In further embodiments, the support block can be provided with a plurality of rollers in contact with the bottom of the track 40, so as to avoid the support block hindering the movement of the track 40 and ensuring the good movement of the track 40.

[0074] As shown in Figure 8 In the embodiment of the present application, the inside of the track 40 is engagedly connected with the track wheel 30 to ensure that the track wheel 30 can stably drive the track 40 to move.

[0075] As shown in Figure 8 In some embodiments, the side shell 11 is provided with a track wheel mounting portion 112, and the track wheel 30 is rotatably sleeved on the track wheel mounting portion 112, so as to drive the track wheel 30 to rotate under the driving of the transmission assembly, and in turn drive the track 40 to run.

[0076] As shown in Figure 8 and Figure 11 In some embodiments, the track wheel 30 is further provided with an annular groove 31 arranged around the track wheel 30, and the inside of the track wheel 30 is provided with a protruding portion 431, which is used to fit and place in the annular groove 31. In this way, through the fitting of the protruding portion 431 and the annular groove 31, the movement of the track 40 can be guided, and the track 40 can be prevented from separating from the track wheel 30 along the axial direction of the track wheel 30, so as to further ensure the stable movement of the track 40.

[0077] As shown in Figures 8 to 10As shown, in some embodiments, the cleaning robot further includes a guiding and positioning structure, which includes multiple guide grooves 61 and multiple guide posts 62.

The multiple guide grooves 61 are located on one of the side shell 11 and the wheel cover 20, and the multiple guide posts 62 are located on the other. The multiple guide posts 62 and multiple guide grooves 61 correspond one-to-one and are connected, enabling positioning and installation between the side shell 11 and the wheel cover 20. This ensures a stable installation position between the side shell 11 and the wheel cover 20 and guarantees the position of the track 40 between them, avoiding obstruction of the track 40's movement and allowing the track 40 to move stably.

[0078] For example, the guide groove 61 is provided on the side of the side shell 11 facing the wheel cover 20, and the guide post 62 is provided on the side of the wheel cover 20 facing the side shell 11.

[0079] For example, the guide positioning structure is disposed between the track wheels 30 and includes four guide grooves 61 and four guide posts 62.

[0080] like Figures 8 to 10 As shown, in some embodiments, the cleaning robot also includes a locking structure, which includes multiple slots 71 and multiple buckles 72. The slots 71 and buckles 72 correspond one-to-one, with the buckles 72 engaging with the slots 71. The locking structure is located between the side shell 11 and the wheel cover 20. The slots 71 are located on one side shell 11 and the wheel cover 20, and the buckles 72 are located on the other side shell 11 and the wheel cover 20. The one-to-one correspondence and connection of the buckles 72 and slots 71 enables a stable installation between the side shell 11 and the wheel cover 20, allowing the wheel cover 20 to protect the structure within the mounting cavity 10a. Furthermore, since the buckles 72 and slots 71 can be quickly disassembled, it also facilitates quick removal of the wheel cover 20 when debris enters the mounting cavity 10a, allowing for inspection and maintenance of the structure within the mounting cavity 10a.

[0081] For example, the slot 71 is provided on the side of the side shell 11 facing the wheel cover 20, and the buckle 72 is provided on the side of the wheel cover 20 facing the side shell 11.

[0082] For example, the engaging structure is provided between the track wheels 30 and includes four slots 71 and four latches 72. Each pair of slots 71 and latches 72 is arranged from the top to the bottom of the side shell 11. Each slot 71 opens towards another slot 71 from the top to the bottom of the side shell 11, and the latches 72 engage with the slots 71 from their openings. In this way, a secure connection between the side shell 11 and the wheel cover 20 can be achieved through the engaging structure.

[0083] like Figure 1 andFigure 8 As shown in the drawings, in the embodiment of the present application, two side shells 11 are arranged on the two sides of the bottom shell 10, each side shell 11 is connected with a wheel cover 20 to form a mounting cavity 10a, and the mounting cavities 10a on the two sides are each provided with a track wheel 30 for driving the movement of the track 40 on the two sides.
