[0024] The embodiments of the utility model will be explained in detail below with reference to the drawings.

[0025] As Figures 1 to 4 The utility model discloses a kind of edge wheel structures facilitating cleaning, including rotatable edge wheel body 1, the edge wheel body 1 includes the cleaning part 2 for cleaning glass dirt, the cleaning part 2 is equipped with brush assembly 3;

[0026] The utility model discloses a kind of edge wheel structures facilitating cleaning, including rotatable edge wheel body 1, the edge wheel body 1 includes the cleaning part 2 for cleaning glass dirt, the cleaning part 2 is equipped with brush assembly 3;

[0027] Further, the setting of brush assembly 3 enables edge wheel body 1 to clean the corner position of window, brush assembly 3 can more effectively reach the corner and edge difficult to reach, which is conducive to significantly improving the comprehensiveness of overall cleaning and effectively ensuring that every part of the window can be thoroughly cleaned.

[0028] Optionally, edge wheel body 1 is installed on window cleaning robot, and edge wheel body 1 is connected with a driving motor or a rotating shaft on the window cleaning robot to drive edge wheel body 1 to rotate.

[0029] Optionally, a sliding mechanism is provided between edge wheel body 1 and the window cleaning robot, so that edge wheel body 1 can rotate during the operation of the window cleaning robot.

[0030] Optionally, in some embodiments, brush assembly 3 is located outside the outer wall of cleaning part 2 and is arranged around the outer wall of cleaning part 2, which facilitates ensuring that brush assembly 3 can comprehensively cover the glass surface contacted by cleaning part 2, including those difficult-to-reach corners and gaps, greatly improving the thoroughness and comprehensiveness of cleaning.

[0031] Further, as a preferred mode of the utility model but not limited, brush assembly 3 is arranged at intervals along the circumferential direction of cleaning part 2.

[0032] As Figures 1 to 4 brush assembly 3 is arranged at intervals along the circumferential direction of cleaning part 2.

[0033] Further, the brush assemblies 3 arranged at intervals in the circumferential direction can ensure that the cleaning force is evenly distributed on the entire cleaning part 2 during rotation, which helps to avoid excessive wear or uneven cleaning caused by concentrating force on a certain point.

[0034] Further, the arrangement at intervals can reduce the mutual friction of the brush assemblies 3 during rotation, thereby reducing the wear rate of the brush assemblies 3, so that the service life of the brush assemblies 3 will be longer, and the user does not need to frequently replace the brush assemblies 3, which helps to reduce maintenance costs.

[0035] Further, the brush assemblies 3 arranged at intervals can increase the cleaning coverage area, so that the stains on the glass surface can be more effectively removed during rotation, which helps to improve the cleaning efficiency.

[0036] As shown in the Figures 1 to 4 cleaning part 2 is provided with a mounting hole 4 for mounting the brush assembly 3 and corresponding to the brush assembly 3;

[0037] Further, by providing the mounting hole 4 on the cleaning part 2, the brush assembly 3 can be conveniently mounted and dismounted through the mounting hole 4, which helps to simplify the process of maintaining and replacing the brush assembly 3, helps to reduce the operation complexity, and effectively improves the maintainability of the equipment.

[0038] Further, the corresponding design of the mounting hole 4 and the brush assembly 3 helps to ensure the firm fixation of the brush assembly 3 on the cleaning part 2, which helps to prevent the brush assembly 3 from loosening or shifting during cleaning, and effectively ensures the stability of the cleaning efficiency and cleaning effect.

[0039] Specifically, the brush assembly 3 is provided with a plurality of groups, and one mounting hole 4 is provided with one group of brush assemblies 3.

[0040] Optionally, in some embodiments, the mounting hole 4 and the brush assembly 3 are detachably connected, and the mounting hole 4 and the brush assembly 3 can adopt threaded connection, buckle connection, slot connection and the like.

[0041] Optionally, in some embodiments, the mounting hole 4 and the brush assembly 3 are fixedly connected, and the user can use a specific adhesive to bond the brush assembly 3 in the mounting hole 4.

[0042] As shown in the Figures 1 to 4 the center axis of the mounting hole 4 is B, and the included angle C between A and B is 0°≤ included angle C≤ 90°;

[0043] Furthermore, by adjusting the size of the angle C, the contact angle between the brush assembly 3 and the glass surface can be optimized. When the angle C is moderate, the brush assembly 3 can fit the glass surface more effectively, thereby improving the cleaning effect. Especially when cleaning the corners of the window, the appropriate angle C can ensure that the brush assembly 3 can penetrate deep into the gaps and remove hard-to-reach stains.

[0044] Optionally, in some embodiments, the angle C = 0°. When the angle C is 0°, the rotation direction of the brush assembly 3 is completely consistent with the central axis of the edge wheel body 1, so that the brush assembly 3 can apply force in a straight line direction during the cleaning process, which is particularly suitable for processing large flat areas, such as large glass or smooth surfaces, and can provide efficient and uniform cleaning effects.

[0045] Optionally, in some embodiments, the angle C = 90°. When the angle C is 90°, the rotation direction of the brush assembly 3 is set perpendicular to the central axis of the edge wheel body 1. Since the brush assembly 3 is perpendicular to the central axis of the edge wheel body 1, a stronger tangential force can be generated during the rotation process, which helps to peel stains from the window surface.

[0046] like Figures 1 to 4 The angle C formed by the central axis A and the central axis B shown is 45°;

[0047] Furthermore, as a preferred embodiment of the present invention but not a limitation, the angle C = 45°. When the angle C is 45°, the brush assembly 3 can exert cleaning force in two main directions, horizontal and oblique. This two-way cleaning action can more effectively cover the surface, which is beneficial to reduce cleaning omissions that may result from cleaning in a single direction. It is especially suitable for complex surfaces that require multi-directional cleaning, such as glass with decorative patterns or uneven surfaces. Secondly, the 45° angle helps to more evenly distribute the force exerted by the brush assembly 3 on the glass surface, which is beneficial to reduce damage caused by excessive local pressure, while also improving the cleaning effect.

[0048] like Figures 1 to 4 The cleaning portion 2 shown includes a first connecting surface 21 and a second connecting surface 22, wherein the first connecting surface 21 and the second connecting surface 22 are connected obliquely and form a rounded corner;

[0049] Furthermore, the rounded corners are set so that the cleaning part 2 can fit more closely when contacting the window surface, which is conducive to reducing cleaning blind spots. The obliquely connected first connecting surface 21 and the second connecting surface 22 can more effectively remove stains on the window surface, especially those located in corners or gaps.

[0050] Furthermore, the rounded corners help disperse stress, reduce the risk of structural damage due to stress concentration, and increase the overall strength and durability of the cleaning portion 2, enabling it to withstand greater external forces and wear.

[0051] Specifically, the first connecting surface 21 is arranged along the vertical direction, and the second connecting surface 22 is arranged to be inclined from the outside to the inside along the horizontal direction, and a chamfer is formed at the connection between the first connecting surface 21 and the second connecting surface 22.

[0052] like Figures 1 to 4 The cleaning portion 2 shown is integrally formed on the side wheel body 1;

[0053] Optionally, in some embodiments, the cleaning portion 2 and the side wheel body 1 are detachably connected, and the cleaning portion 2 and the side wheel body 1 can be connected by threaded connection, snap connection, lock connection, slot connection, etc.

[0054] Furthermore, as a preferred embodiment of the present invention but not a limitation, the cleaning part 2 is integrally formed on the side wheel body 1. The integrally formed setting enables the cleaning part 2 and the side wheel body 1 to become a whole, which is conducive to avoiding structural instability caused by loosening or falling off of connecting parts, helping to improve the rigidity of the entire equipment, and effectively reducing deformation or breakage caused by vibration or external force during use, thereby ensuring the long-term and stable operation of the equipment; secondly, the integrally formed setting can reduce the assembly links between the cleaning part 2 and the side wheel body 1, effectively avoiding performance degradation due to assembly errors.

[0055] like Figures 1 to 4 The side wheel body 1 shown includes a support portion 5 connected to the cleaning portion 2, and the cross section of the support portion 5 is circular;

[0056] Furthermore, the support portion 5 with a circular cross-section can evenly distribute the pressure from the cleaning portion 2, which is beneficial to avoiding local deformation or breakage caused by uneven force, and helps to enhance the connection stability between the support portion 5 and the cleaning portion 2, effectively ensuring the long-term stable operation of the equipment; secondly, the circular cross-section is beneficial to enhancing the rigidity and bending resistance of the support portion 5. Even under high load or vibration environment, the support portion 5 can maintain its shape and function, effectively improving the overall rigidity of the equipment.

[0057] Furthermore, the circular cross-section enables the support portion 5 to move more smoothly during the rolling process, which helps to reduce friction and resistance, and helps to improve the movement efficiency of the cleaning portion 2 on the window surface, making the cleaning process easier and more efficient.

[0058] like Figures 1 to 4 The support portion 5 shown includes a first support surface 51, and a chamfer is formed at the connection between the first support surface 51 and the inner wall of the side wheel body 1;

[0059] Furthermore, the setting of the chamfered corners helps to disperse stress and reduce the risk of structural damage caused by stress concentration. When the side wheel body 1 is subjected to external forces, the chamfered corners can more effectively transmit and disperse these forces, thereby protecting the overall structure of the support part 5 and the side wheel body 1.

[0060] Furthermore, the rounded corners help reduce the direct contact area between the support portion 5 and the window surface or other components during rolling, thereby reducing the risk of wear, which not only extends the service life of the support portion 5 but also reduces the noise and vibration caused by wear.

[0061] like ​ A window cleaning robot shown includes a robot body and a side wheel structure for facilitating cleaning as described above, connected to the robot body;

[0062] Optionally, a plurality of side wheel bodies 1 are provided on the robot body.

[0063] Furthermore, the robot body is connected to the edge wheel body 1 so that the robot body can effectively remove stubborn stains on the glass, especially stains with strong stickiness, which is conducive to improving the cleaning effect; secondly, by arranging the edge wheel body 1 on the robot body, the robot body can clean the edges and corners of the window, effectively reducing dead corners during cleaning, thereby thoroughly removing stains and dust.
