Description

Technical Field

[0002] This application belongs to the technical field of window cleaning machines, and particularly relates to a wheel skin and a window cleaning robot.

Background Art

[0004] In the cleaning and maintenance of modern high-rise buildings, as an efficient cleaning tool, the performance and stability of a window cleaning machine are crucial for ensuring the cleaning effect. However, the existing design of the wheel skin of a window cleaning machine has certain limitations. Since the friction coefficient of the wheel skin is constant, during the cleaning process of the window cleaning machine, when facing smooth and water-stained or oil-stained glass surfaces, the friction force between the wheel skin and the glass does not match, and it is not sufficient to support the stable movement of the window cleaning machine, thus prone to slipping, which affects the normal working efficiency of the window cleaning machine. In order to match the corresponding wheel skin, the wheel skin of the window cleaning machine needs to be replaced.

Utility Model Content

[0006] To solve the problem that the window cleaning machine is prone to slipping when cleaning water-stained or oil-stained glass surfaces in the prior art, this application provides a wheel skin and a window cleaning robot.

[0007] This application is achieved through the following technical solutions:

[0008] A wheel skin includes an inner belt and an outer belt connected to the inner belt and disposed around the outside of the inner belt. The outer belt includes at least two contact surfaces with different friction coefficients facing away from the inner belt.

[0009] For a wheel skin as described above, the difference in the rolling friction coefficient between different contact surfaces and the glass surface is A, where A > 0.03.

[0010] For a wheel skin as described above, the difference in the sliding friction coefficient between different contact surfaces and the glass surface is B, where B > 0.03.

[0011] For a wheel skin as described above, it includes at least one first contact surface and at least one second contact surface, and the first contact surface and the second contact surface are located on the same curved surface.

[0012] For a wheel skin as described above, each of the first contact surfaces and each of the second contact surfaces are arranged vertically.

[0013] For a wheel skin as described above, each of the first contact surfaces and each of the second contact surfaces are arranged alternately along the circumferential direction.

[0014] For a wheel skin as described above, a plurality of wheel teeth are provided on the inner side wall of the inner belt.

[0015] A window cleaning robot includes a wheel skin as described in any one of the above.

[0016] Compared with the prior art, the present application has the following advantages:

[0017] A wheel skin and a window cleaning robot of the present application integrate two or more contact surfaces with different friction coefficients on the surface of the outer wheel skin in contact with the glass surface. The smaller friction coefficient allows the window cleaning machine to move more smoothly on the smooth glass surface, and the higher friction coefficient has a better anti-slip effect, enabling the window cleaning machine to maintain good adhesion and stability on dry, wet or oily glass surfaces, thereby effectively avoiding slipping and ensuring that the window cleaning machine can smoothly perform the cleaning operation.

Detailed Embodiments

[0023] In order to make the technical problems, technical solutions and beneficial effects solved by the present application more clearly understood, the following further details the present application in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0024] Please refer to Figures 1 to 2 , a wheel skin, including an inner belt 1 and an outer belt 2 connected to the inner belt 1 and disposed around the outer side of the inner belt 1. The outer belt 2 includes at least two contact surfaces 3 with different friction coefficients facing away from the inner belt 1.

[0025] A wheel skin and a window cleaning robot of the present application integrate two or more contact surfaces with different friction coefficients on the surface of the outer wheel skin in contact with the glass surface. The smaller friction coefficient allows the window cleaning machine to move more smoothly on the smooth glass surface, and the higher friction coefficient has a better anti-slip effect, enabling the window cleaning machine to maintain good adhesion and stability on dry, wet or oily glass surfaces, thereby effectively avoiding slipping and ensuring that the window cleaning machine can smoothly perform the cleaning operation.

[0026] Further, as a preferred implementation manner rather than a limitation of this solution, the difference in the rolling friction coefficient between different contact surfaces 3 and the glass surface is A, where A > 0.03.

[0027] In this embodiment, the adaptability of the wheel skin under different surface conditions can be improved, especially on dry, wet or oil-stained glass surfaces encountered during the cleaning process. Due to the difference in the friction coefficient, the wheel skin of the window cleaning machine can provide better adhesion and stability, thus effectively reducing the slipping phenomenon and ensuring the smooth operation and efficient cleaning of the window cleaning machine. The difference in the friction coefficient of the contact surface can be adjusted according to different cleaning requirements and environmental conditions to achieve the best cleaning effect. For example, if the glass surface to be cleaned is particularly smooth or has a special coating, the adhesion can be enhanced by increasing the difference in the friction coefficient of the contact surface; on the contrary, if the glass surface is relatively rough, the difference in the friction coefficient can be appropriately reduced to reduce wear. This flexibility enables the wheel skin to adapt to a wider range of application scenarios, improving the versatility and practicality of the window cleaning robot.

[0028] Further, as a preferred implementation manner rather than a limitation of this solution, the difference between the sliding friction coefficients of different contact surfaces 3 and the glass surface is B, where B > 0.03.

[0029] In this embodiment, the adaptability and stability of the window cleaning machine under different surface conditions are enhanced. Especially when there are water stains or oil stains on the glass surface, the slipping phenomenon during the sliding of the window cleaning machine on the glass surface can be effectively prevented by adjusting the sliding friction coefficients of different contact surfaces, ensuring its stability and safety during the cleaning process. When cleaning relatively smooth glass, a smaller difference in the friction coefficient can be selected to reduce the frictional resistance and improve the cleaning speed; while when cleaning glass with a relatively rough surface or stains, a larger difference in the friction coefficient can be selected to enhance the adhesion and improve the cleaning effect.

[0030] Further, as a preferred implementation manner rather than a limitation of this solution, it includes at least one first contact surface 31 and at least one second contact surface 32, and the first contact surface 31 and the second contact surface 32 are located on the same curved surface.

[0031] In this embodiment, since the first contact surface 31 and the second contact surface 32 share the same curved surface, they can work together to adapt to the minute unevenness of the glass surface, reduce the friction force fluctuation caused by surface non-uniformity, and make the window cleaning machine operate more smoothly. And realizing contact surfaces with different friction characteristics on the same wheel skin provides better adaptability for the window cleaning machine, enabling it to cope with different cleaning conditions and glass surfaces of different materials. For example, during the cleaning process, if it encounters particularly smooth or glass with a special coating, the first contact surface 31 can provide sufficient friction force to prevent slipping, while the second contact surface 32 can provide greater friction force to enhance adhesion when needed.

[0032] Further, as a preferred implementation manner rather than a limitation of this solution, each of the first contact surfaces 31 and each of the second contact surfaces 32 are arranged in the vertical direction.

[0033] In the first embodiment, as Figure 1 shown, this arrangement can improve the stability and adaptability of the wheel skin during the window cleaning process, especially when performing cleaning operations on vertical or inclined glass surfaces. Since the contact surfaces are distributed in the vertical direction, they can better conform to the contour of the glass surface, reducing the uneven friction caused by surface irregularities or slight inclinations, thereby reducing the vibration and swaying of the window cleaning machine during operation and improving the cleaning efficiency and quality. In addition, this vertically arranged design also helps to improve the durability of the wheel skin. Since the contact surfaces are evenly distributed, the wear will also be more uniform, extending the service life of the wheel skin. At the same time, this design simplifies the maintenance and replacement process of the wheel skin because the arrangement of the contact surfaces makes it more convenient to inspect and replace worn parts.

[0034] Further, as a preferred implementation manner rather than a limitation of this solution, each of the first contact surfaces 31 and each of the second contact surfaces 32 are arranged in a staggered pattern along the circumferential direction.

[0035] In the second embodiment, as Figure 2 shown, this staggered arrangement pattern can provide a more balanced friction distribution when the window cleaning robot contacts the glass surface, effectively preventing the wheel skin from slipping or the unstable movement of the window cleaning machine caused by uneven friction. Secondly, the staggered arrangement in the circumferential direction enhances the adaptability of the wheel skin to different surface features. Whether it is a flat or slightly concave-convex glass surface, good adhesion and stability can be ensured. In addition, this arrangement also helps to reduce the problem of uneven wear of the wheel skin after long-term use because each contact surface will alternately bear the friction, thereby extending the overall service life of the wheel skin. At the same time, this design also facilitates the modularization of the wheel skin, enabling the worn contact surface to be quickly replaced and simplifying the maintenance work.

[0036] Further, as a preferred implementation manner rather than a limitation of this solution, a plurality of teeth 11 are provided on the inner side wall of the inner belt 1.

[0037] In this embodiment, the overall structural stability and durability of the wheel skin are improved. It can effectively prevent the relative sliding or displacement of the wheel belt during high-load or long-term operation, ensuring that the window cleaning robot can maintain precise control and consistent performance under various operating conditions.

[0038] The present utility model also discloses a window cleaning robot, including a kind of wheel skin as described above. The window cleaning robot cooperates with the kind of wheel skin to work with higher window cleaning efficiency.

[0039] The working principle of this embodiment is as follows:

[0040] A kind of wheel skin and window cleaning robot of the present application integrates two or more contact surfaces with different friction coefficients on the surface of the outer wheel skin that contacts the glass surface. The smaller friction coefficient can make the window cleaning machine move more smoothly on the smooth glass surface, and the higher friction coefficient has a better anti-slip effect, which can enable the window cleaning machine to maintain good adhesion and stability on dry, wet or oily glass surfaces, thereby effectively avoiding slipping and ensuring that the window cleaning machine can smoothly carry out cleaning operations.

[0041] The above are the implementation manners provided in combination with specific contents, and it is not determined that the specific implementation of the present application is only limited to these descriptions. Any similarity in the method structure of the present application or several technical deductions or replacements made under the premise of the concept of the present application should be regarded as the protection scope of the present application.
