[0002] As people's living standards improve and they pursue a higher quality of life, swimming pools have become popular recreational venues. Whether it's a private or public pool, the cleanliness of the water is a primary concern. Therefore, cleaning robots have emerged in the market in recent years, used for cleaning the bottom and walls of pools. Pool cleaning robots are typically equipped with tracks and wheels, with a cover plate installed between two spaced-ahead tracks. When the robot is cleaning underwater, the cover plate is prone to collisions with the pool walls, steps, or corners due to their close proximity. Long-term collisions and friction can cause scratches, wear, and even deformation on the cover plate surface, affecting the robot's aesthetic appearance. Utility Model Content

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0037] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0038] like Figures 1 to 2 As shown, this application provides a self-moving cleaning device, including a device body 300, a moving mechanism 200 and a cleaning mechanism 400. The moving mechanism 200 is disposed at the bottom of the device body 300 and is used to drive the device body 300 to move. The cleaning mechanism 400 is disposed on the device body 300 and is used to clean the surface of the work area to maintain the cleanliness of the work area.

[0039] It should be noted that the cleaning mechanism 400 can be a first roller brush located at the front end of the main body 300, or it can be a first roller brush and a second roller brush located at the front and rear ends of the main body 300. Both the first roller brush and the second roller brush are used to clean the mud, dirt, algae and other foreign objects from the bottom and side walls of the pool to keep the pool clean.

[0040] In an optional embodiment, the moving mechanism 200 includes track wheels 201 and a track 202. The track wheels 201 include a first track wheel 201 and a second track wheel 201, which are disposed on opposite sides of the equipment body 300 and spaced apart along the front and rear of the equipment body 300. The track 202 is fitted over the outer sides of the first track wheels 201 and the second track wheels 201 to support the weight of the equipment body 300 and reduce its pressure on the ground, thereby improving the adhesion and stability of the equipment body 300. The first track wheels 201 and the second track wheels 201 engage with the track 202 through teeth, allowing the track 202 to rotate smoothly, thereby moving the equipment body 300 so that the first roller brush and / or the second roller brush can clean the surface of the working area.

[0041] In an optional embodiment, the cover assembly 100 includes a cover structure 10 and a protective structure 20 made of wear-resistant material. The cover structure 10 is disposed on the outside of the moving mechanism 200, and the protective structure 20 is disposed on the cover structure 10 and at least partially protrudes from the outer surface of the cover structure 10. This prevents the cover structure 10 from directly colliding or rubbing against the pool sidewall, steps, corners, or other obstacles during the movement of the equipment body 300, thus avoiding scratches, wear, or even deformation on the cover structure 10, which could lead to damage to the cover structure 10 and a reduction in its service life.

[0042] After adopting the above technical solutions, such as Figures 3 to 5 As shown, the cover assembly 100 includes a cover structure 10 and a protective structure 20. The protective structure 20 protrudes partially from the surface of the cover structure 10, allowing it to preferentially contact the pool's sidewalls, steps, corners, or other obstacles. The protective structure 20 absorbs the energy generated during contact or collision with the cover structure 10 through deformation or wear, thus preventing damage to the cover structure 10, such as scratches, wear, and deformation. The protective structure 20 has wear-resistant properties, reducing friction when colliding with obstacles and preventing wear, making its surface less prone to scratches from external forces. Alternatively, the protective structure 20 can be fixed to the cover structure 10 by means of clips, bolts, or embedding, ensuring that the cover assembly 100 remains secure during long-term use and is easy to replace, thus balancing the strength and wear resistance of the cover assembly 100.

[0043] In an optional embodiment, the cover structure 10 covers the space between the first track wheel 201 and the second track wheel 201 and protrudes outward from the track 202. This not only allows the main body of the equipment 300 to preferentially contact the pool sidewall, steps, corners or other obstacles during movement, thus preventing the side of the track 202 from being scratched, but also prevents foreign objects such as ropes or gravel from entering the gaps of the track wheel 201 and causing the track wheel 201 to jam.

[0044] In an optional embodiment, a dynamic gap is formed between the cover plate structure 10 and the track wheel 201 and / or track 202. This not only ensures that the track 202 does not rub against the cover plate structure 10 when rotating, but also prevents large particles or other foreign objects from entering the track wheel 201 and / or track 202. The dynamic gap is in the range of 3 mm to 5 mm.

[0045] In an alternative embodiment, the portion of the cover plate structure 10 that protrudes from the track 202 can be transitioned by a sloped structure or an arc structure, which can guide obstacles to slip away upon collision and reduce the impact of lateral impact force on the track wheel 201.

[0046] In an optional embodiment, the cover structure 10 has a convex surface 11, and a protective structure 20 is arranged around the outer periphery of the convex surface 11 to provide precise protection for high-risk collision areas of the cover structure 10. When the cover structure 10 comes into contact with the pool sidewall, steps, corners or other obstacles, the protective structure 20 arranged around the outer periphery of the convex surface 11 forms a protective ring that contacts the edge of the obstacle. By deforming and raising the protective structure 20, the convex surface 11 is prevented from being scratched.

[0047] In an optional embodiment, the convex surface 11 is a convex arc-shaped surface, which can not only guide the water flow smoothly through the cover structure 10, reducing the turbulent resistance when the robot moves and improving the propulsion efficiency; but also prevent the accumulation of dirt such as algae or leaves, so that it can be more easily removed when the water flow washes it off. It can even absorb some energy through the elastic deformation of the protective ring on the outer side of the convex arc-shaped surface during collision, reducing the transmission of vibration.

[0048] In an optional embodiment, the protective structure 20 extends at least partially along the convex surface 11 toward the front end of the cover assembly 100, which can prevent the front end of the cover assembly 100 from colliding or rubbing against the pool sidewall, steps, corners or other obstacles, thereby achieving enhanced protection for the front collision area of ​​the cover assembly 100.

[0049] For example, the protective structure 20 has an extension 21, the width of which decreases from the rear end to the front end of the cover structure 10. This not only reduces the weight of the cover structure 10, but also ensures the impact resistance of the front end of the cover structure 10.

[0050] In one alternative implementation, such as Figures 6 to 8As shown, the protective structure 20 includes a soft rubber layer 23, which is fixed to the outer surface of the cover structure 10. This makes the cover structure 10 not only have excellent buffering performance, effectively absorbing the impact force generated by the collision and reducing the vibration impact on the cover and the robot body, but also have good wear resistance and anti-aging performance, and can withstand friction with the side wall, steps or corners of the pool for a long time.

[0051] For example, the soft rubber layer 23 is made of a highly elastic and wear-resistant soft material. It is fixed to the outer surface of the cover plate structure 10 by bonding or injection molding. The elastic deformation of the soft rubber layer 23 absorbs the impact energy, which not only prevents the cover plate structure 10 from being damaged during a collision and extends its service life, but also increases the traction of the main body of the equipment 300 on the slope or smooth pool sidewall by utilizing the high coefficient of friction of the soft rubber layer 23, preventing the track 202 from spinning, thus achieving multiple goals of impact resistance and anti-slip.

[0052] In an alternative embodiment, the outer surface of the soft rubber layer 23 is formed with an uneven or textured structure, which can not only enhance the anti-slip and wear-resistant properties of the protective structure 20, but also guide water flow in a specific direction and reduce turbulence.

[0053] For example, the textured or corrugated structure can be wavy, granular, or striped to disperse the energy generated when the protective structure 20 collides with the pool sidewall, steps, corners, or other obstacles, and can also reduce the contact area between the protective structure 20 and the pool sidewall, steps, corners, or other obstacles, further reducing the risk of wear.

[0054] In an optional embodiment, the protective structure 20 includes a hard rubber layer 24 and a soft rubber layer 23 disposed on the hard rubber layer 24. The hard rubber layer 24 is fixedly connected to the cover structure 10 to achieve a fixed connection between the protective structure 20 and the cover structure 10, ensuring a stable connection between the soft rubber layer 23 and the cover structure 10. The soft rubber layer 23 protrudes from the surface of the cover structure 10 to contact pool sidewalls, steps, or corners, etc., which not only protects the cover structure 10 from damage, reduces noise during impacts, and extends its service life, but also facilitates the disassembly and assembly of the protective structure 20, making subsequent maintenance and replacement easier.

[0055] In an optional embodiment, the cover plate structure 10 is provided with a mounting groove 12, and the protective structure 20 is fitted into the mounting groove 12, so that the protective structure 20 can be firmly fixed on the cover plate structure 10, which significantly improves the maintainability and environmental adaptability of the product while ensuring the protective performance.

[0056] In one optional embodiment, the mounting groove 12 is provided with a plug hole 22, and the protective structure 20 is provided with a plug post 121, so that the protective structure 20 and the cover plate structure 10 can be quickly positioned and fixed through the precise cooperation between the plug post 121 and the plug hole 22.

[0057] In an optional embodiment, a flow-guiding structure is provided on the outer surface of the cover structure 10 and / or the protective structure 20 to guide water flow through the cover assembly 100, reducing the water flow resistance on both sides of the equipment body 300 when it moves in water. This not only improves the movement efficiency of the equipment body 300 and reduces energy consumption, but also enhances the stability and cleaning effect of the equipment body 300 in complex aquatic environments. At the same time, the flow-guiding structure can also reduce the impact of water flow on the cover structure 10 and the protective structure 20, further extending their service life.

[0058] In one alternative embodiment, the flow guiding structure can be a streamlined groove, a corrugated pattern, or a fin-like protrusion, etc., which are not limited in this application. Its main purpose is to guide the water flow smoothly.

[0059] In one optional embodiment, the protective structure 20 includes a first protective structure 20a and a second protective structure 20b. The convex surface 11 includes a first convex surface 11a and a second convex surface 11b spaced apart along the front-rear direction of the cover plate structure 10. The mounting groove 12 includes a first mounting groove 12a and a second mounting groove 12b. The first mounting groove 12a is arranged around the outer periphery of the first convex surface 11a, and the second mounting groove 12b is arranged around the outer periphery of the second convex surface 11b. The first protective structure 20a is fixed in the first mounting groove 12a, and the second protective structure 20b is fixed in the second mounting groove 12b. The structure of the first protective structure 20a may be the same as or different from the structure of the second protective structure 20b, and this application does not impose any limitations on this.
