[0033] To make the objectives, technical solutions, and advantages of the present disclosure more clear, the present disclosure will be further described in detail below with reference to the accompanying drawings. It is apparent that the embodiments described are only a portion of the embodiments of the present disclosure, rather than all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present disclosure without creative effort are intended to fall within the scope of protection of the present disclosure.

[0034] It should also be noted that the terms "include," "comprises," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a product or device comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such product or device.

[0035] In the related art, cleaning equipment, such as a sweeping robot, etc., generates abnormal noise when cleaning the operating surface, causing discomfort to the user and affecting the user experience.

[0036] An embodiment of the present disclosure provides a roller brush, comprising: a shaft and a brush component, wherein the brush component is coaxially arranged on the outside of the shaft, and the brush component is configured to clean an operating surface as the roller brush rotates; wherein, at least a portion of the outer surface of the brush component is provided with a noise reduction film layer, and the noise reduction film layer is configured to reduce noise generated when cleaning the operating surface.

[0037] The roller brush provided in the embodiment of the present disclosure reduces the noise generated when cleaning the operating surface by providing a noise reduction film layer on at least a portion of the outer surface of the brush component, thereby improving the user experience of the roller brush during the cleaning process.

[0038] The optional embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0039] Figures 1 and 2 are schematic diagrams of a cleaning device according to an exemplary embodiment. The roller brush provided in the embodiment of the present application can be applied to the cleaning device. As an example, the cleaning device can be a vacuum robot, a mopping / brushing robot, a window climbing robot, etc. The cleaning device can include a mobile platform 1000, a perception system 2000, a control system (not shown), a drive system 3000, an energy system (not shown), a human-computer interaction system 4000, and a cleaning module 5000. Among them:

[0040] The mobile platform 1000 can be configured to move along a target direction on an operating surface. The operating surface can be the surface to be cleaned by the cleaning device. In some embodiments, the cleaning device can be a mopping robot, where the cleaning device operates on the ground, with the ground being the operating surface. The cleaning device can also be a window cleaning robot, where the cleaning device operates on the exterior glass surface of a building, with the glass being the operating surface. The cleaning device can also be a pipe cleaning robot, where the cleaning device operates on the interior surface of a pipe, with the interior surface of the pipe being the operating surface. For illustrative purposes only, the following description of this application uses a mopping robot as an example.

[0041] In some embodiments, mobile platform 1000 can be either an autonomous or non-autonomous mobile platform. An autonomous mobile platform means that the mobile platform 1000 itself can adaptively make operational decisions based on unexpected environmental inputs. A non-autonomous mobile platform cannot adaptively make operational decisions based on unexpected environmental inputs, but can execute established programs or operate according to certain logic. Accordingly, when mobile platform 1000 is an autonomous mobile platform, the target direction can be determined autonomously by the cleaning device; when mobile platform 1000 is a non-autonomous mobile platform, the target direction can be set by the system or manually.

[0042] The perception system 2000 includes a position determination device (not shown in the figure) located above the mobile platform 1000, a buffer (not shown in the figure) located on the forward part of the mobile platform 1000, a cliff sensor (not shown in the figure) and an ultrasonic sensor (not shown in the figure) located at the bottom of the mobile platform, an infrared sensor (not shown in the figure), a magnetometer (not shown in the figure), an accelerometer (not shown in the figure), a gyroscope (not shown in the figure), an odometer (not shown in the figure) and other sensing devices, which provide the control system with various position information and motion status information of the machine.

[0043] For the convenience of description, the following directions are defined: the cleaning equipment can be calibrated by defining the following three mutually perpendicular axes: the transverse axis Y, the front-back axis X, and the vertical axis Z. The direction of the arrow along the front-back axis X is marked as "backward", and the direction opposite to the arrow direction along the front-back axis X is marked as "forward". The transverse axis Y is essentially along the width of the cleaning equipment. The direction of the arrow along the transverse axis Y is marked as "left", and the direction opposite to the arrow along the transverse axis Y is marked as "right". The vertical axis Z is the direction extending upward from the bottom surface of the self-cleaning equipment. As shown in Figure 1, the direction along the front-back axis X is defined as the second direction, and the second direction is, for example, forward or backward; the direction perpendicular to the second direction in the horizontal plane is the first direction, and the first direction is, for example, left or right.

[0044] The control system (not shown in the figure) is set on the circuit motherboard in the mobile platform 1000, including a computing processor, such as a central processing unit, an application processor, which communicates with a non-temporary memory, such as a hard disk, a flash memory, or a random access memory. The application processor is configured to receive the environmental information sensed by the multiple sensors transmitted by the perception system, and use a positioning algorithm, such as SLAM, based on the obstacle information fed back by the position determination device to draw a real-time map of the environment in which the cleaning equipment is located, and autonomously determine the driving path based on the environmental information and the environmental map, and then control the drive system 3000 to perform forward, backward and / or steering operations based on the autonomously determined driving path. Furthermore, the control system can also decide whether to start the cleaning module 5000 for cleaning operations based on the environmental information and the environmental map.

[0045] The drive system 3000 can execute a drive command based on specific distance and angle information, such as x, y and θ components, to manipulate the cleaning equipment to travel across the ground. The drive system 3000 includes a drive wheel assembly, and the drive system 3000 can control the left and right wheels at the same time. In order to more accurately control the movement of the machine, the preferred drive system 3000 includes a left drive wheel assembly and a right drive wheel assembly respectively. The left and right drive wheel assemblies are symmetrically arranged along the transverse axis defined by the mobile platform 1000. In order for the cleaning equipment to move more stably on the ground or to have stronger movement ability, the cleaning equipment may include one or more steering assemblies, and the steering assembly may be a driven wheel or a driving wheel. Its structural form includes but is not limited to a universal wheel, and the steering assembly may be located in front of the driving wheel assembly.

[0046] The energy system (not shown) includes rechargeable batteries, such as nickel-metal hydride batteries and lithium batteries. The rechargeable batteries can be connected to a charging control circuit, a battery pack charging temperature detection circuit, and a battery undervoltage monitoring circuit. These circuits are then connected to the microcontroller control circuit. The host computer is charged via charging electrodes located on the side or bottom of the device.

[0047] The human-machine interaction system 4000 includes buttons on the main unit panel for users to select functions; a display screen and / or indicator lights and / or a speaker to display the current machine status or function options to the user; and a mobile client application. For route-guided cleaning equipment, the mobile client can display a map of the equipment's environment and the machine's location, providing users with a richer and more user-friendly set of functions.

[0048] FIG2 is a bottom view of the cleaning device in FIG1 . As shown in FIG2 , the cleaning module 5000 is assembled on the mobile platform 1000 , for example, is disposed at the bottom of the mobile platform 1000 , and is configured to clean the operating surface.

[0049] FIG3 is a schematic structural diagram of a cleaning module 5000 provided in some embodiments of the present disclosure, and FIG4 is a schematic cross-sectional diagram of a cleaning module 5000 provided in some embodiments of the present disclosure. As shown in FIG3 and FIG4 , the cleaning module 5000 further includes a driving unit 5100, a roller brush frame 5200, and a roller brush 5300 assembled in the roller brush frame 5200. The driving unit 5100 provides a forward or reverse driving force, and applies the driving force to the roller brush 5300 through a multi-stage gear set. The roller brush 5300 rotates under the action of the driving force to clean the operating surface, or the roller brush 5300 rotates under the action of the driving force to collect dust.

[0050] The roller brush 5300 is assembled within the roller brush frame 5200 and is arranged along a first direction perpendicular to the front-rear axis of the mobile platform 1000. The number of roller brushes 5300 can be determined based on actual conditions. In some embodiments, referring to FIG. 4 , the number of roller brushes 5300 is two, namely a first roller brush 100 and a second roller brush 200, wherein the second roller brush 200 is arranged in a direction parallel to the first roller brush 100.

[0051] 5 , the roller brush 5300 includes a shaft 110 and a brush member 130. The brush member 130 is coaxially disposed outside the shaft 110 and is configured to clean the operating surface as the roller brush 5300 rotates. A noise reduction film 135 is disposed at least partially on the outer surface of the brush member 130 to reduce noise generated when cleaning the operating surface.

[0052] At least one end of the shaft 110 is connected to a multi-stage gear set to receive the driving force of the drive unit 5100 and realize forward or reverse rotation. The shaft 110 is in the shape of an elongated cylindrical bar, an elongated square bar, or an elongated polygonal bar. There is no limitation on this. The elongated cylindrical bar will be used as an example for explanation. The axis of the shaft 110 can be regarded as the rotation axis of the roller brush 100. When the roller brush 5300 is installed on the mobile platform, the drive system can drive the shaft 110 to rotate, thereby driving the brush component 130 on the surface of the shaft 110 to clean.

[0053] In some embodiments, the roller brush 5300 further includes a filler 120, which is disposed between the shaft 110 and the brush member 130, and the filler 120 is coaxial with the shaft 110. The cross-section of the filler 120 is an annular structure, and the inner ring shape of the filler 120 matches the cross-sectional shape of the shaft 110. The inner ring shape can be circular, directional, polygonal, etc., which is not limited to this. The following explanation is given by taking the inner ring as an example. The outer ring shape of the filler 120 is generally circular. When the cross-section of the filler 120 is annular, the cross-section of the filler 120 has an inner diameter and an outer diameter. The inner diameter is substantially equal to the diameter of the shaft 110 to achieve seamless fitting of the filler 120 and the shaft 110, and the outer diameter is substantially equal to the inner diameter of the cylindrical member 131 to achieve seamless fitting of the filler 120 and the cylindrical member 131.

[0054] Filler 120 is a compressible elastic material that compresses inward when subjected to force and returns to its original shape when the force is removed. Examples include sponges, organic flexible materials, resin materials, and foam materials, though these are not exhaustive. Furthermore, filler 120 may also be a hollow material or structure with similar compressibility, such as a spring or shrapnel, though these are not exhaustive.

[0055] The brush component 130 is sleeved on the outside of the filler 120 , and the brush component 130 includes a cylindrical component 131 and a brush piece 132 .

[0056] In some embodiments, the brush member 130 is formed of a soft rubber material. Specifically, in some embodiments, the brush member 132 is formed of a soft rubber material. Soft rubber materials may be, for example, TPU (Thermoplastic Urethane), TPE (Thermoplastic Elastomer), rubber, PVC (Polyvinyl chloride), etc. Soft rubber materials have excellent elasticity and can deform elastically when interfering with the operating surface, thereby cleaning the operating surface.

[0057] In some embodiments, the brush assembly 130 further includes a cylindrical member 131 and a brush member 132, wherein the cylindrical member 131 is sleeved on the outside of the shaft 110, and the brush member 133 extends from the outer surface of the cylindrical member 131 in a direction away from the cylindrical member 131. The brush member 132 is configured to interfere with the operating surface to clean the operating surface.

[0058] The cylindrical member 131 is mounted on the outside of the shaft 110 and is coaxial with the shaft 110. The cylindrical member 131 is typically cylindrical and has a length substantially the same as that of the shaft 110. The cylindrical member 131 is typically compressible, for example, made of elastic plastic or rubber. It can be compressed inward and deformed under external force, returning to its original shape after the external force is removed. The cylindrical member 131 is typically thick to enhance the wear resistance of the brush member 130.

[0059] In some embodiments, the roller brush 5300 further includes a filler 120 , and in this case, the cylindrical member 131 is mounted on the outside of the filler 120 .

[0060] The brush member 132 extends from the outer surface of the cylindrical member 131 in a direction away from the cylindrical member 131. The brush member 132 can be a plurality of sheet-like structures, and at least one brush member 132 extends from one end of the cylindrical member 131 to the other end of the cylindrical member 131 along the axial direction of the cylindrical member 131. The brush member 132 can be a blade, bristle or other form.

[0061] In some embodiments, there are multiple brush members 132, each of which has a spiral structure on the outer surface of the cylindrical member 131. The multiple brush members 132 are roughly evenly distributed along the circumference of the cylindrical member 131, and the spiral structures of the multiple brush members 132 are roughly parallel. By designing the brush members 132 as a spiral structure, the front and rear roller brushes can easily roll up garbage when they rotate in opposite directions, without generating excessive impact force and damaging the brush members 132, thereby extending their service life.

[0062] The noise reduction layer 135 is disposed on at least a portion of the outer surface of the brush member 130 to reduce noise generated when the brush member 130 cleans the operating surface. In some embodiments, the noise reduction layer 135 is disposed on at least the portion of the brush member 132 that interferes with the operating surface to reduce noise generated when the brush member 132 interferes with the operating surface. In other embodiments, the noise reduction layer 135 is disposed on both the outer surface of the cylindrical member 131 and the outer surface of the brush member 132.

[0063] In some embodiments, the coefficient of friction between the noise reduction film layer 135 and the operating surface is less than the coefficient of friction between the brush member 132 and the operating surface. Specifically, it can be less than the coefficient of friction between the portion of the brush member 132 that interferes with the operating surface and the operating surface, so that the friction between the brush member 132 provided with the noise reduction film layer 135 and the operating surface is less than the friction between the brush member 132 and the operating surface without the noise reduction film layer 135. It can be seen that when the noise reduction film layer 135 is provided on the surface of the brush member 132 of the roller brush 5300, the friction between the brush member 132 and the operating surface is reduced, thereby reducing the noise between the roller brush 5300 and the operating surface. In some embodiments, the friction coefficient of the noise reduction film layer 135 is less than a preset friction coefficient value.

[0064] In some embodiments, the noise reduction film layer 135 has a smoother surface than the brush 132. Specifically, it may be smoother than the portion of the brush 132 that interferes with the operating surface. By forming a smooth film layer on the surface of the brush 132, the noise between the roller brush 5300 and the operating surface can be reduced.

[0065] In some embodiments, the elastic modulus of the noise reduction film layer 135 is greater than the elastic modulus of the brush member 132, so that the brush member 132 provided with the noise reduction film layer 135 deforms more when colliding with the operating surface than the brush member 132 without the noise reduction film layer 135, thereby reducing the noise between the brush member 132 and the operating surface. In some embodiments, the elastic modulus of the noise reduction film layer 135 is greater than a predetermined elastic modulus value.

[0066] In some embodiments, the friction coefficient between the noise reduction film layer 135 and the operating surface is smaller than the friction coefficient between the brush member 132 and the operating surface, and the elastic modulus of the noise reduction film layer 135 is larger than the elastic modulus of the brush member 132. For example, the friction coefficient of the noise reduction film layer 135 is set to be smaller than a preset friction coefficient value, and the elastic modulus of the noise reduction film layer 135 is set to be greater than a preset elastic modulus value.

[0067] In some embodiments, the noise reduction film layer 135 can be at least one of a polyparaxylene film and a Teflon (or polytetrafluoroethylene, PTFE) film. Films made of polyparaxylene or Teflon can improve the surface smoothness of the brush member 132, reduce friction between the brush member 132 and the operating surface, and thus reduce noise generated by the rolling brush 5300 and the operating surface.

[0068] In some embodiments, the thickness of the noise reduction film layer 135 can range from 0.05 to 0.3 microns. A noise reduction film layer 135 that is too thick may affect the overall thickness and elasticity of the brush member 132, and an excessively thick noise reduction film layer 135 may easily fall off the surface of the brush member 132. A noise reduction film layer 135 that is too thin may be less resistant to wear and tear, affecting the noise reduction effect.

[0069] In some embodiments, the noise reduction film layer 135 is formed by a chemical vapor deposition (CVD) method. Specifically, the chemical vapor deposition method can adopt a vacuum nano-coating preparation process. The following is an example of forming a polyparaxylene film on the surface of the brush component 130 by the chemical vapor deposition method. The entire process of chemical vapor deposition needs to be carried out under vacuum conditions. The dimer of paraxylene decomposes into active monomers at high temperatures. The active monomers are deposited on the surface of the object (such as the surface of the brush component 130) and polymerized into a completely covered film. The chemical vapor deposition method can be used for surface coating of any shape without dead angles. The surface of any shape includes sharp edges and corners, inside gaps and extremely fine pinholes, and the film thickness of the film deposited by chemical vapor deposition on any part of the product is very uniform. The thickness of the polyparaxylene film generated by chemical vapor deposition is 0.05 to 0.3 microns.

[0070] In some embodiments, the noise reduction film layer 135 is applied by spraying, brushing, or rolling. Spraying involves using a spray gun or a disc atomizer to disperse the sprayed paint into uniform and fine droplets using pressure or centrifugal force, and then applying the droplets to the surface of the object being coated. Brushing involves dipping a paintbrush into the applied paint and coating the surface of the object being coated. Rolling involves dipping a roller brush into the applied paint and coating the surface of the object being coated.

[0071] As an example, the Teflon film can be achieved by surface spraying. Teflon is a material with very low friction. After Teflon is sprayed on the surface of the brush component 130, it can reduce the friction between the brush component 130 and the operating surface, thereby achieving the purpose of eliminating noise.

[0072] The embodiment of the present disclosure further provides a cleaning device, including the aforementioned roller brush 5300.

[0073] In some embodiments, the cleaning device includes a mobile platform configured to move on the operating surface; a cleaning module assembled on the mobile platform and configured to clean the operating surface, the cleaning module including: a roller brush arranged along a first direction perpendicular to the front and rear axis of the mobile platform.

[0074] The roller brush includes a shaft and a brush component, the brush component is coaxially arranged on the outside of the shaft, and the brush component is configured to clean the operating surface as the roller brush rotates; wherein, at least a portion of the outer surface of the brush component is provided with a noise reduction film layer, and the noise reduction film layer is configured to reduce the noise generated when cleaning the operating surface.
