Description

Technical Field

[0001] This disclosure relates to the field of smart home technology, and more specifically, to a cable sheath, cleaning device, and cleaning system. Background Technology

[0002] As society continues to develop and people's living standards improve, cleaning robots are becoming increasingly popular in households because they save time and effort compared to traditional manual cleaning. A typical cleaning robot consists of the main unit and a high-speed rotating cleaning component that mops the floor.

[0003] Currently, some cleaning robots are equipped with motion mechanisms for their cleaning components, enabling them to lift and / or extend to handle different cleaning scenarios. However, during these lifting and / or extending movements, some wiring harnesses are splintered due to the movement.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this disclosure is to provide a wire sheath, cleaning equipment, and cleaning system that provide protection for wire harnesses.

[0006] According to one aspect of this disclosure, a cable sheath is provided for cleaning equipment, the cable sheath comprising: A sleeve having a fixed end and a free end, the sleeve having a wire harness hole extending from the fixed end to the free end to penetrate the sleeve, and the free end of the sleeve having at least one wire harness clearance notch.

[0007] In one exemplary embodiment of this disclosure, the free end of the sleeve is provided with wire harness clearance notches on both end walls along a first direction, the first direction being perpendicular to a second direction, and the second direction being the direction from the free end to the fixed end.

[0008] In one exemplary embodiment of this disclosure, the cable sheath further includes: The mounting part surrounds the sleeve body, and the cable sheath is fixedly assembled through the mounting part; the sleeve body is made of elastic material, or both the sleeve body and the mounting part are made of elastic material.

[0009] In one exemplary embodiment of this disclosure, a plurality of reinforcing ribs are formed on the sleeve body. The reinforcing ribs surround the sleeve body circumferentially and are spaced apart along a second direction, which is the direction from the fixed end to the free end.

[0010] In one exemplary embodiment of this disclosure, the free end of the sleeve is oriented toward at least a portion of the fixed end, and the dimension of the free end decreases radially along a second direction in the sleeve, the second direction being the direction in which the free end points toward the fixed end.

[0011] In one exemplary embodiment of this disclosure, the sleeve is frustum-shaped.

[0012] In one exemplary embodiment of this disclosure, the clearance notch is V-shaped or U-shaped.

[0013] In one exemplary embodiment of this disclosure, a chamfer is formed between the inner wall of the wire harness hole and the end face of the free end.

[0014] According to another aspect of this disclosure, a cleaning apparatus is provided, the cleaning apparatus comprising: Equipment body; A cleaning module, which is movable relative to the device body along a first direction; A conductive wire harness, one end of which is connected to the device body and the other end of which is connected to the cleaning module; The aforementioned wire sheath is disposed on the cleaning module, the conductive wire harness passes through the wire harness hole, and the wire harness clearance notch is disposed on the end wall of the sheath body along the first direction; the first direction is perpendicular to the second direction, and the second direction is the direction from the free end to the fixed end.

[0015] In one exemplary embodiment of this disclosure, the depth of the clearance notch in the second direction and / or the maximum width of the clearance notch in the radial direction of the sheath is greater than or equal to the diameter of the conductive wire harness.

[0016] In one exemplary embodiment of this disclosure, the cleaning module includes a cleaning component, a mounting frame, and a first drive assembly. The cleaning component is rotatably connected to the mounting frame, and the first drive assembly is disposed on the mounting frame and used to drive the cleaning component to rotate. The cleaning device further includes a second drive assembly, which is disposed on the device body and is at least capable of driving the mounting bracket to move relative to the device body along the first direction.

[0017] In one exemplary embodiment of this disclosure, the cleaning module further includes: A shielding member is rotatably connected to the mounting bracket and is movable relative to the mounting bracket between an open position and a shielded position to shield or expose the cleaning component; A third drive assembly is mounted on the mounting bracket and is used to drive the shielding member to move between the open position and the shielding position; the third drive assembly is electrically connected to the device body through the conductive wire harness.

[0018] In one exemplary embodiment of this disclosure, the cable sheath further includes a mounting portion surrounding the sheath body, the mounting portion being clamped and fixed to the mounting bracket by a pressure plate; at least a portion of the sheath body is located on the side of the mounting portion closer to the device.

[0021] According to another aspect of this disclosure, a cleaning system is provided, the cleaning system comprising: The aforementioned cleaning equipment; A base station, which is used to interface with the cleaning equipment.

[0022] The cable sheath provided in this disclosure addresses the issue that when the cleaning module of the cleaning equipment is in motion, the conductive wire harness extending from the cleaning module can be stretched, leading to tearing of the insulation layer or even conductor breakage. The cable sheath effectively wraps around this extension, acting as a buffer layer against contact with other structures and preventing the conductive wire harness from being cut. Furthermore, the extension area is where the conductive wire harness experiences the most concentrated deformation during cleaning module movement; the wire harness clearance notch, located at the free end of the cable sheath and aligned with this deformation-concentrated area, provides clearance for bending and stretching, reducing fatigue damage and wear, and improving the reliability and lifespan of the conductive wire harness.

[0039] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0040] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0041] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first,” “second,” and “third,” etc., are used only as markers and are not a limitation on the number of objects.

[0042] Embodiments of this disclosure provide a cleaning system, such as Figures 1-3 As shown, the cleaning system includes a cleaning device 10 and a base station 20. The cleaning device 10 can be, for example, a mopping robot, a sweeping robot, or a combined sweeping and mopping robot; the cleaning device 10 may include a device body 30, a drive module, a sensing module, a control module, a cleaning module, an energy module, and a human-machine interaction module. The base station 20 is used to dock with the cleaning device 10, allowing it to be parked. The cleaning device 10 can perform functions such as charging, self-cleaning, docking, sewage discharge, water replenishment, and dust collection on the base station 20.

[0043] In some embodiments, the device body 30 is configured to automatically move along a target direction on a travel surface, which can be the surface to be cleaned by the cleaning device 10. If the cleaning device 10 is a sweeping and mopping robot, then the cleaning device 10 operates on the ground.

[0044] In some embodiments, the drive module may include a drive wheel assembly. The drive module can control both the left and right wheels simultaneously. For more precise control of the machine's movement, the drive module preferably includes a left drive wheel assembly and a right drive wheel assembly. The left and right drive wheel assemblies are symmetrically arranged along a transverse axis defined by the device body 30. In some embodiments, to enable the cleaning device 10 to move more stably or with greater mobility on the ground, the cleaning device 10 may include one or more steering wheels. The steering wheels may be driven wheels or drive wheels, and their structural forms include, but are not limited to, casters. The steering wheels may be located in front of the drive wheel assembly, and a drive motor provides power to the drive wheel assembly and / or the steering wheels.

[0045] In some embodiments, the cleaning device 10 may be a self-propelled cleaning device. The sensing module may include a position determination device located above the device body 30, a buffer located on the forward portion of the device body 30, and a cliff sensor and ultrasonic sensor, infrared sensor, magnetometer, accelerometer, gyroscope, odometer, and other sensing devices located at the bottom of the device body 30, providing the control module with various position and motion state information of the device body 30. For example, the forward portion of the device body 30 is provided with a buffer. During the cleaning process, when the drive wheel assembly propels the cleaning device 10 to walk on the ground, the buffer detects one or more objects in the travel path of the cleaning device 10 via a sensor module, such as a collision sensor. The cleaning device 10 can pass through the objects detected by the collision sensor, such as steps, obstacles, or walls, and the control drive structure makes the cleaning device 10 respond to the objects, such as stepping over steps.

[0046] In some embodiments, the control module can combine distance and speed information fed back from sensors such as buffers, cliff sensors, ultrasonic sensors, infrared sensors, magnetometers, accelerometers, gyroscopes, and odometers to comprehensively determine the current working state of the robot vacuum cleaner, such as climbing stairs, crossing thresholds, walking on carpets, being on a cliff, stuck above or below, having a full dustbin, or being picked up. It will also provide specific next action strategies for different situations, making the cleaning device 10 work more in line with the user's requirements and providing a better user experience. Furthermore, the control module can plan the most efficient and reasonable cleaning path and cleaning method based on real-time map information drawn using SLAM (Simultaneous Localization and Mapping), which can improve the cleaning efficiency of the cleaning device 10.

[0047] In some embodiments, the energy module may include a rechargeable battery, such as a nickel-metal hydride battery or a lithium battery. The rechargeable battery may 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 a microcontroller control circuit. The main unit is charged by connecting to a charging station via charging electrodes located on the side or bottom of the device.

[0048] In some embodiments, the human-machine interface module may include buttons on the main control panel for users to select functions; it may also include a display screen and / or indicator lights and / or a speaker, which display the current status of the machine or the available function options to the user; and it may also include a mobile client application. For path navigation cleaning equipment, the mobile client can display a map of the environment where the equipment is located, as well as the machine's position, and can provide users with richer and more user-friendly functions.

[0049] In some embodiments, the cleaning module may include a dry cleaning module, or a dry and wet cleaning module. The dry cleaning module may include a roller brush assembly, side brushes, etc., while the wet cleaning module may include cleaning components, a water tank, etc. Figure 3 As shown, the cleaning component 41 in the wet cleaning module can be a mopping component, such as a roller mop or a tracked mop, to mop the surface to be cleaned.

[0050] Among them, such as Figure 4 As shown, a roller mop can be mounted on the equipment body 30 via mounting bracket 42, enabling it to clean the area to be cleaned along the travel path of the equipment body 30 under the drive of the equipment body 30. During cleaning, the roller mop is driven by a drive motor to rotate relative to the mounting bracket 42, rolling and wiping the surface to be cleaned during rotation, thus efficiently removing dirt. To improve the cleaning efficiency of the roller mop during the rolling and wiping process, cleaning fluid can be sprayed onto it, so that the roller mop is wetted before rolling and wiping the surface to be cleaned, thereby further improving cleaning efficiency. Similarly, a tracked mop can also be mounted on the equipment body 30 via mounting bracket 42 and rolled and wiping the surface to be cleaned after being wetted by spraying cleaning fluid.

[0051] When the cleaning equipment 10 includes a wet cleaning module, the equipment body 30 is typically equipped with a removable wastewater box assembly to collect wastewater generated during the cleaning operation of the wet cleaning module. Specifically, the mop is sprayed with cleaning fluid to clean the surface, leaving wastewater on the mop area. Before the next cleaning, this wastewater needs to be scraped off, and the surface can be re-sprayed with cleaning fluid to improve the cleaning effect.

[0052] In some embodiments, such as Figure 4 and Figure 5 As shown, the cleaning module 40 includes a cleaning component 41, a mounting frame 42, and a first drive assembly. The cleaning component 41 is assembled on the mounting frame 42, which has a receiving portion. The cleaning component 41 is located in the receiving portion and is rotatably connected to the mounting frame 42. The first drive assembly is disposed on the mounting frame 42 and is used to drive the cleaning component 41 to rotate. For example, the cleaning component 41 may be a hollow structure with a receiving space. The first drive assembly may be located in the receiving space of the cleaning component 41. The stator portion of the first drive assembly is fixedly connected to the mounting frame 42, and the rotor is fixedly connected to the cleaning component 41, thereby driving the rotation of the cleaning component 41 through the first drive assembly.

[0053] The cleaning device 10 also includes a second drive assembly 43, which is mounted on the device body 30 and used to drive the cleaning module 40 to move, specifically driving the mounting bracket 42 of the cleaning module 40 to move relative to the device body 30. The second drive assembly 43 can be connected to the mounting bracket 42 via a connector 44, allowing the connector 44 to drive the mounting bracket 42 to move synchronously. The second drive assembly 43 includes a driver, a transmission component, and a drive housing. The driver is configured to at least drive the transmission component to reciprocate between a first position and a second position along a first direction X. The drive housing has a through hole extending along the first direction X, and the other end of the connector 44 passes through the through hole and connects to the transmission component. When the transmission component is in the first position, the cleaning component 41 is in the retracted position. During the movement of the transmission component from the first position to the second position, the drive housing limits the movement of the connector 44 along the first direction X, and the transmission component drives the connector 44 to move upwards along the second direction Z toward the transmission component. When the transmission component is in the second position, the cleaning component 41 is in the raised position. In the second direction Z, the height of the cleaning component 41 relative to the ground of the device body 30 when it is in the raised position is greater than the height of the cleaning component 41 relative to the ground of the device body 30 when it is in the retracted and extended positions. The first direction X is perpendicular to the second direction Z. The first direction X can be the left-right direction of the device body 30, and the second direction Z can be the height direction of the device body 30.

[0054] During normal cleaning, the cleaning device 10 uses the second drive assembly 43 to position the transmission component in the first position, i.e., the cleaning component 41 is in the retracted position, allowing the cleaning component 41 to continuously perform cleaning operations on the surface to be cleaned. In cleaning scenarios where the cleaning device 10 operates, there are often areas that do not require mopping, such as carpets in a user's home. However, a damp, dust-laden roller mop will wet or soil these areas, severely impacting the user experience. In this case, the second drive assembly 43 can position the transmission component in the second position, raising the cleaning component 41 to a raised position to prevent the damp mop from contacting carpets or other surfaces that need to be avoided. After the cleaning device 10 moves away from carpets or other surfaces, the second drive assembly 43 can move the transmission component back to the first position, allowing the cleaning component 41 to descend back to the retracted position and continue cleaning the surface.

[0055] In some embodiments, such as Figure 4 and Figure 6 As shown, the driver is configured to also drive the transmission member to reciprocate between a first position and a third position along a first direction X, with the first position located between a second position and a third position along the first direction X; when the transmission member is in the third position, the cleaning member 41 is in the extended position; in the first direction X, the cleaning member 41 extends outward from the device body 30 relative to the retracted position when it is in the extended position.

[0056] When the cleaning component 41 is in the raised and retracted positions, the orthographic projection of the device body 30 in the second direction Z covers the orthographic projection of the cleaning component 41 in the second direction Z, meaning that the cleaning component 41 is located inside the device body 30 when it is in the raised and retracted positions. When the cleaning component 41 is in the extended position, the orthographic projection of the cleaning component 41 in the second direction Z protrudes beyond the orthographic projection of the device body 30 in the second direction Z along the first direction X, meaning that the cleaning component 41 moves to protrude beyond the outer contour of the device body 30, allowing the cleaning component 41 to cover a wider cleaning area.

[0057] When the cleaning device 10 encounters hard-to-reach areas such as walls, corners, and table legs during the cleaning process, the second drive assembly 43 can move the transmission component to the third position, which in turn drives the cleaning component 41 to the extended position via the connecting component 44. This allows the cleaning component 41 to cover the hard-to-reach areas, improving the cleaning effect. After the cleaning device 10 has finished cleaning the hard-to-reach areas, the second drive assembly 43 can move the transmission component back to the first position, allowing the cleaning component 41 to return to the retracted position and continue cleaning the surface to be cleaned.

[0058] The switching between the retracted and extended positions of the cleaning component 41 can be considered as a horizontal movement along the first direction X. That is, in the height direction (second direction Z) of the device body 30, the height of the cleaning component 41 above the ground is the same when the transmission component is in the first and third positions. The switching between the retracted and raised positions of the cleaning component 41 can be considered as a diagonal linear movement or a linear movement in the height direction. That is, in the height direction of the device body 30, the height of the cleaning component 41 above the ground when the transmission component is in the second position is greater than the height of the cleaning component 41 above the ground when the transmission component is in the first and third positions, so as to achieve the lifting of the cleaning component 41.

[0059] In some embodiments, the transmission member is provided with an inclined surface. When the transmission member is in the first position, the end of the connector 44 located in the through hole on the drive housing is located at the bottom of the inclined surface. At this time, if the transmission member moves from the first position to the second position under the drive of the driver, since the drive housing is fixedly connected to the device body 30, the connector 44 cannot continue to move along the first direction X under the drive of the transmission member. Therefore, the movement of the connector 44 in the first direction X can be regarded as a stationary state. However, since the transmission member is provided with an inclined surface and the transmission member moves relative to the connector 44 in the first direction X, the end of the connector 44 connected to the transmission member slides from the bottom to the top of the inclined surface. That is, during the process of the transmission member moving from the first position to the second position, the connector 44 is stationary in the first direction X, but moves upward through the inclined surface in the second direction Z, so it can drive the cleaning member 41 to be lifted upward. Until the transmission member moves to the second position, the end of the connector 44 connected to the transmission member can be located at the top of the inclined surface, thereby driving the cleaning member 41 to be in a raised position and achieving the lifting effect of the cleaning head. When the cleaning component 41 needs to be lowered from the raised position to the retracted position, the transmission component moves from the second position toward the first position. At this time, the end of the connector 44 connected to the transmission component can move from the top of the inclined plane toward the bottom. When the transmission component moves to the first position, the end of the connector 44 slides from the inclined plane to the bottom of the inclined plane, so that the cleaning component 41 is in the retracted position after it is lowered.

[0060] When the cleaning component 41 needs to move from the retracted position to the extended position, the driver drives the transmission component to move from the first position to the third position. At this time, the transmission component pushes the end of the connecting component 44 to move synchronously in the first direction X, thereby causing the cleaning component 41 to move towards the extended position. When the transmission component moves to the third position, the cleaning component 41 moves to the extended position. When the cleaning component 41 needs to retract from the extended position to the retracted position, the driver drives the transmission component to move from the third position to the first position. At this time, the transmission component pushes the end of the connecting component 44 to move synchronously in the first direction X, thereby causing the cleaning component 41 to move towards the retracted position. When the transmission component moves to the first position, the cleaning component 41 moves to the retracted position.

[0061] It is understood that by having at least one fourth position between the first and third positions, the cleaning member 41 can be extended to at least one position between the retracted position and the extended position, thereby enabling adjustment of the extension distance of the cleaning member 41 to adapt to more usage scenarios.

[0062] In some embodiments, such as Figure 7 and Figure 8 As shown, the cleaning module 40 may further include a shielding member 45 and a third driving assembly 46. The first side of the cleaning member 41 along the second direction Z is used to contact the surface to be cleaned. The shielding member 45 is movable relative to the cleaning member 41 between an open position and a shielded position. When the shielding member 45 is in the open position, the first side of the cleaning member 41 is exposed from the shielding member 45 at least along the second direction Z. When the shielding member 45 is in the shielded position, the shielding member 45 shields the first side of the cleaning member 41 at least in the second direction Z. The third driving assembly 46 is connected to the shielding member 45 and is used to drive the shielding member 45 to move between the open position and the shielded position.

[0063] When the blocking member 45 is in the open position, the first side of the cleaning member 41 is exposed from the blocking member 45 at least along the second direction Z. At this time, the cleaning member 41 can make normal contact with the surface to be cleaned, realizing an effective mopping and cleaning function, ensuring good cleaning performance in areas that need cleaning (such as hard floors). When the cleaning device 10 travels to an area that does not need mopping (such as carpet), the third drive assembly 46 drives the blocking member 45 to the blocking position. At this time, the blocking member 45 blocks the first side of the cleaning member 41 at least in the second direction Z. That is, the blocking member 45 is located between the cleaning member 41 and the area that does not need mopping, completely preventing the cleaning member 41 from contacting the area that does not need mopping, thereby avoiding wetting or soiling the area that does not need mopping, greatly improving the user experience. When the cleaning device 10 leaves the area that does not need mopping and travels back to the area that needs cleaning, the third drive assembly 46 drives the blocking member 45 from the blocking position to the open position, so that the first side of the cleaning member 41 is exposed from the blocking member 45 again, and the mopping and cleaning of the surface to be cleaned continues.

[0064] The third drive component 46 may include a servo motor, which drives the blocking component 45 to move between an open position and a blocked position. Driving the blocking component 45 with a servo motor enables precise control of its position, resulting in greater stability and reliability. This allows for quick and accurate response to the cleaning needs of the cleaning equipment 10 for different areas, improving the intelligence and efficiency of the cleaning equipment 10. Furthermore, the servo motor's small size facilitates integration into the cleaning equipment 10, minimizing the space it occupies. Of course, the third drive component 46 can also be other types of drive motors.

[0065] When the cleaning component 41 is a roller mop, the blocking component 45 can be positioned at the bottom of the roller mop along the second direction Z to block the roller mop; the blocking component 45 can also be positioned to the side of the roller mop along the third direction Y or above the roller mop along the second direction Z to allow the roller mop to protrude and contact the surface to be cleaned. The third direction Y is perpendicular to the first direction X and the second direction Z, and the third direction Y can be the front-back direction of the device body 30.

[0066] The cleaning component 41 extends in the first direction X, and its two ends can be rotatably connected to the mounting bracket 42 in the first direction X, so that the cleaning component 41 can quickly rotate and wipe the surface to be cleaned.

[0067] The first drive component and the third drive component 46 in the cleaning module 40 need to be electrically connected to the device body 30 via conductive wire harnesses to provide power from the battery on the device body 30 and control signals from the circuit board on the device body 30. However, since the first drive component and the third drive component 46 are mounted on the mounting bracket 42, the conductive wire harnesses connecting the first drive component and the third drive component 46 also move with the mounting bracket 42 as the mounting bracket 42 moves. However, when the conductive wire harnesses move with the mounting bracket 42, they may interfere with other components in the cleaning module 40. After long-term mutual friction, some conductive wire harnesses may break, resulting in open circuits and / or short circuits, affecting the user experience.

[0068] In this regard, the present disclosure provides a cable protection sleeve 50, which includes a sleeve body 51. The sleeve body 51 has a fixed end and a free end. The sleeve body 51 has a wire harness hole 53, which extends from the fixed end to the free end to penetrate the sleeve body 51. The free end of the sleeve body 51 is provided with at least one wire harness avoidance notch 54.

[0069] The cable sheath 50 provided in this disclosure protects the conductive wire harness from being pulled when the cleaning module 40 of the cleaning device 10 is in motion, which could lead to tearing of the insulation layer or even breakage of the conductor. The cable sheath 50 effectively wraps around this portion, acting as a buffer layer against contact with other structures and preventing the conductive wire harness from being cut. Furthermore, the portion of the conductive wire harness extending from the cleaning module 40 is the area of ​​greatest deformation during movement; the wire harness clearance notch 54, located at the free end of the cable sheath 50 and aligned with this deformation-concentrated area, provides clearance for bending and stretching, reducing fatigue damage and wear, and improving the reliability and lifespan of the conductive wire harness.

[0070] like Figures 9-11As shown, the cable sheath 50 can be mounted on the mounting bracket 42 of the cleaning module 40. At least a portion of the cable sheath 50 is located on the side closer to the device body 30. When the conductive wire harness is electrically connected to the first drive assembly and the device body 30, it passes through the cable sheath 50. The wire harness clearance notch 54 on the free end of the cable sheath 50 approaches the device body 30 along the second direction Z. The direction in which the free end and the fixed end of the cable sheath 50 point to each other is the second direction Z, that is, the height direction of the cable sheath 50 is the height direction of the device body 30.

[0071] When the mounting bracket 42 of the cleaning module 40 is lifted and extended under the drive of the second drive assembly 43, the portion of the conductive wire harness extending from the mounting bracket 42 will be pulled, causing the insulation layer to tear or even the conductor to break. The protective sleeve 50 wraps around the portion of the conductive wire harness extending from the mounting bracket 42, making the protective sleeve 50 a buffer layer in contact with other structures, thereby preventing the conductive wire harness from being cut. Specifically, when the cleaning component 41 is lifted, the portion of the conductive wire harness extending from the device body 30 to the mounting bracket 42 will bend upwards, with the center of the bend located on one side of the device body 30; when the cleaning component 41 is extended, the conductive wire harness will be stretched and bent in the direction in which the cleaning component 41 extends, with the center of the bend located on one side of the mounting bracket 42. It can be seen that in both movements, the part where the conductive wire harness is led out from the mounting bracket 42 is the area with the most concentrated deformation and the largest deformation amplitude. The wire harness avoidance notch 54 is set at the edge of the opening of the protective sleeve 50 near the equipment body 30, aligned with the area of ​​concentrated deformation of the conductive wire harness, providing avoidance space for the bending and stretching of the conductive wire harness: when the conductive wire harness bends upward, the notch can accommodate the bent part of the conductive wire harness, avoiding the conductive wire harness being squeezed by the upper edge of the opening of the protective sleeve 50; when the conductive wire harness stretches outward, the notch can allow the conductive wire harness to move along the direction of the notch, avoiding being stuck by the side edge of the opening, reducing the restriction of the protective sleeve 50 on the movement of the conductive wire harness, thereby reducing fatigue damage and wear of the conductive wire harness, and improving the reliability of the cleaning equipment 10.

[0072] It should be noted that the conductive wire harness can connect the first driving component to the device body 30, and can also connect the first driving component to the device body 30 and the second driving component 43 to the device body 30. The conductive wire harness may include multiple wires, some of which may be power lines and some of which may be control lines. In addition, the wires in the conductive wire harness may also be detection lines to connect to other detection devices or other devices installed on the cleaning module 40, and this disclosure does not limit this.

[0073] In some embodiments, such as Figures 10-13As shown, the cable sheath 50 includes a mounting part 52 and a sheath body 51. The cable sheath 50 is connected to the mounting frame 42 via the mounting part 52, and at least a portion of the sheath body 51 is located on the side of the mounting part 52 closer to the equipment. The mounting part 52 requires high strength and high stability, while the sheath body 51 requires flexibility and wear resistance. The split structure allows for the selection of different materials for the two parts, enabling material allocation as needed. This ensures stable fixation on the mounting frame 42 while precisely protecting the moving area of ​​the conductive wire harness.

[0074] The mounting part 52 surrounds the sleeve 51 and is clamped and fixed to the mounting bracket 42 by a pressure plate 422. The surrounding mounting part 52 provides support force throughout the circumference of the sleeve 51. Regardless of the direction from which the conductive wire harness applies radial thrust, the mounting part 52 can disperse stress through its surrounding structure, keeping the sleeve 51 centered and preventing tilting. Simultaneously, the clamping force between the pressure plate 422 and the mounting bracket 42 fixes the mounting part 52. The large contact area between the pressure plate 422 and the mounting part 52 allows for even distribution of clamping force throughout the circumference of the mounting part 52, preventing excessive local stress that could cause deformation and further enhancing connection stability. Furthermore, the surrounding mounting part 52 can be designed with positioning structures (such as protrusions or grooves on the outer wall of the mounting part 52), and corresponding positioning grooves (or positioning holes) can be designed on the pressure plate 422 or the mounting bracket 42. During assembly, the cooperation of the protrusions and grooves improves assembly accuracy and efficiency.

[0075] Among them, such as Figure 10 As shown, the mounting bracket 42 is provided with a through hole 421, and the cable sleeve 50 is provided on the through hole 421. Then, the pressure plate 422 with a through hole passes through the sleeve body 51 and presses on the mounting part 52. Then, the pressure plate 422 and the mounting bracket 42 are fixedly connected by screws 423. The clamping force of the pressure plate 422 and the mounting bracket 42 in clamping and fixing the mounting part 52 is adjusted by the tightening force of the screws 423.

[0076] In some embodiments, the sleeve 51 of the cable sheath 50 is made of an elastic material, or both the sleeve 51 and the mounting part 52 are made of elastic materials. The elastic material sleeve 51 (e.g., silicone, rubber, elastic plastic, etc.) can adapt to the movement of the conductive wire harness through its own deformation. When the conductive wire harness is bent and stretched, the elastic sleeve 51 will deform accordingly with the bending or stretching direction of the conductive wire harness, reducing friction with the conductive wire harness and achieving flexible wrapping of the conductive wire harness, ensuring the protective effect while avoiding excessive restraint. At the same time, the wire harness clearance notch 54 on the elastic material sleeve 51 can adjust its size in real time with the deformation of the conductive wire harness. When the deformation of the conductive wire harness is large, the edge of the notch will be pushed outward by the conductive wire harness to increase the clearance space; when the deformation decreases, the notch will shrink under the action of elastic restoring force, still maintaining the protection of the conductive wire harness. Of course, the sleeve 51 can also be made of a rigid material, such as rigid plastic, and this disclosure does not limit this.

[0077] In some embodiments, such as Figures 11-13 As shown, multiple reinforcing ribs 55 are formed on the sleeve 51. The reinforcing ribs 55 surround the sleeve 51 circumferentially and are spaced apart in the height direction (second direction Z) of the sleeve 51. The sleeve 51 will bear bending load when the conductive wire harness is bent. The reinforcing ribs 55 surrounding the sleeve 51 circumferentially can increase the cross-sectional thickness of the sleeve 51, improve the structural strength of the sleeve 51, and thus improve its bending resistance. In addition, the design of the reinforcing ribs 55 adopts local reinforcement rather than overall thickening, which maximizes the control of weight increase while improving strength, achieving a balance between strength and lightweight.

[0078] In some embodiments, at least a portion of the free end of the sleeve 51 facing the fixed end decreases in size radially along the height direction of the sleeve 51. When the conductive wire harness moves with the cleaning component 41, its deformation trajectory exhibits a gradual transition from the mounting bracket 42 to the device body 30. The conductive wire harness near the mounting bracket 42 exhibits a smaller movement amplitude, while the movement amplitude near the device body 30 is larger. The gradual structure of the sleeve 51 can increase the structural strength of the free end where the wire harness avoidance notch 54 is provided, preventing excessive bending of the elastic material sleeve 51.

[0079] Among them, such as Figure 11 As shown, the sleeve 51 is shaped like a frustum. When the sleeve 51 is subjected to a bending moment, the multiple sides of the frustum can bear stress in different directions, making the stress distribution more uniform. For example, when the quadrangular frustum sleeve 51 bends, two opposite sides bear tensile stress, and the other two sides bear compressive stress. The stress is transmitted to the mounting part 52 through the edges of the frustum. The multi-plane structure of the frustum shape can provide more stable support, enhance the deformation resistance of the sleeve 51, and avoid stress concentration on a single plane, which could cause the sleeve 51 to collapse.

[0080] Among them, such as Figures 11-13 As shown, the wire harness clearance notch 54 is V-shaped or U-shaped. The acute angle of the V-shaped notch can guide the conductive wire harness to bend along the notch direction, which is especially suitable for scenarios where the cleaning component 41 needs to be lifted or extended quickly. For example, when the cleaning component 41 is suddenly lifted, the conductive wire harness can bend upward quickly under the guidance of the V-shaped notch, avoiding bending lag caused by the notch angle being too large, and reducing the risk of the conductive wire harness being squeezed by the edge of the opening of the wire sheath 50. The wide arc of the U-shaped notch can accommodate a large range of movement of the conductive wire harness. For example, when the cleaning component 41 needs to extend a long distance, the sliding path of the conductive wire harness in the U-shaped notch is longer. The arc structure can guide the conductive wire harness to move along the arc of the notch, reducing friction and stress concentration caused by linear movement. Of course, the wire harness clearance notch 54 can also be spherical cap or spherical segment, or irregular in shape, and this disclosure does not limit it.

[0081] Among them, such as Figures 11-13As shown, along the axial direction of the rotation of the cleaning component 41, the free ends of the cable sheath 50 are respectively provided with wire harness clearance notches 54 on opposite end walls in the first direction X. The movement of the cleaning component 41 typically includes a combination of outward and retraction movements. The wire harness clearance notches 54 on opposite sides of the opening edge of the cable sheath 50 can simultaneously avoid the movement of the conductive wire harness in both outward and retraction directions. This bidirectional clearance improves the freedom of movement of the conductive wire harness and avoids movement restrictions caused by a single-direction notch.

[0082] The wire sheath 50 can be configured as a symmetrical structure to achieve foolproof assembly and improve assembly efficiency.

[0083] In some embodiments, a chamfer may be formed between the inner wall of the wire harness hole 53 and the end face of the free end. The sharp edge between the inner wall and the end face of the rigid wire sheath 50 increases the frictional resistance with the conductive wire harness; during the movement of the cleaning component 41, the conductive wire harness may rub against the inner wall and end face edge of the wire sheath 50; the chamfer design can transform the sharp edge into a smooth transition surface, making the contact between the conductive wire harness and the wire sheath 50 a smooth transition and reducing wear.

[0084] The chamfer can be either a circular chamfer or a linear chamfer; this disclosure does not impose any restrictions on this.

[0085] In some embodiments, the depth of the harness clearance notch 54 in the height direction of the sheath 50 and / or the maximum width of the harness clearance notch 54 in the radial direction of the sheath 50 may be greater than or equal to the diameter of the conductive harness. The depth and width of the notch directly affect the clearance space of the conductive harness. If the notch depth is insufficient, the conductive harness may be squeezed by the top edge of the opening edge of the sheath 50 when bending; if the notch width is insufficient, the conductive harness may be stuck by the two sides of the notch when stretching. The notch size limitation ensures that the conductive harness is completely inserted into the notch during movement. When the conductive harness is bent or stretched, its bent or stretched portion can be completely accommodated within the notch, and the top and sides of the opening edge of the sheath 50 will not exert excessive pressure on the conductive harness, thereby improving the service life of the conductive harness.
