Description

Technical Field

[0001] This utility model relates to the field of cleaning technology, and in particular to a cleaning device. Background Technology

[0002] Currently, cleaning devices (such as robotic vacuum cleaners) typically rely on the friction between the fibers of their cleaning components (like rollers or brushes) and the floor to remove dirt when cleaning hard surfaces. However, when these devices encounter carpets, the fibers easily come into contact with the carpet, transferring stains from the fibers to the carpet and thus contaminating it. This is especially true when the cleaning components are in a wet cleaning mode, as the wet components are more likely to wet the carpet and transfer water stains, causing even greater contamination. This not only limits the application scenarios of cleaning devices and reduces their versatility but also leads to a poorer user experience and satisfaction. Utility Model Content

[0003] This invention provides a cleaning device that can improve the problem of cleaning devices easily causing carpet contamination during cleaning operations.

[0004] This utility model provides a cleaning device, which includes: a body, a lifting mechanism, a cleaning mechanism, and a shielding component; the lifting mechanism is connected to the body; the cleaning mechanism is connected to the lifting mechanism and moves up and down relative to the body under the drive of the lifting mechanism; the cleaning mechanism includes a cleaning component; the shielding component is rotatably mounted on the cleaning mechanism and partially shields the outer periphery of the cleaning component, the shielding component has a first rotational position that isolates the cleaning component from the surface to be cleaned, and a second rotational position that allows the cleaning component to contact the surface to be cleaned; wherein, the lifting mechanism includes a driving component and a transmission mechanism, the transmission mechanism includes a power input end and two power output ends, the driving component drives the two power output ends to move through the power input end, one of the two power output ends drives the cleaning mechanism to move up and down, and the other of the two power output ends drives the shielding component to rotate.

[0005] The beneficial effects of this design are as follows: The cleaning equipment is equipped with a lifting mechanism that drives the cleaning unit to move up and down. By controlling the lifting of the cleaning unit, the cleaning component can remain separated from the surface to be cleaned in the vertical direction of the cleaning equipment. When the cleaning equipment passes over a carpet, this separation achieves physical isolation between the cleaning component and the carpet, thereby reducing the probability of contact between the cleaning component and the carpet, and thus reducing the possibility of residual stains or moisture on the cleaning component contaminating the carpet. In addition, the cleaning equipment also has a rotatable shield. The shield can switch between a first rotation position and a second rotation position, thereby achieving isolation or contact between the cleaning component and the surface to be cleaned. When the cleaning equipment passes over a carpet, the shield can be rotated to the first rotation position. At this time, the shield is located between the carpet and the cleaning component, which can further block the contact path between the cleaning component and the carpet, further reducing the probability of residual stains or water on the cleaning component contaminating the carpet.

[0006] Furthermore, this embodiment benefits from using a single drive unit to drive the lifting of the cleaning mechanism and the rotation of the shielding component, thus reducing the number of drive units required. This not only lowers the manufacturing cost of the cleaning equipment but also saves installation space, facilitating a compact design. Simultaneously, since the lifting of the cleaning mechanism and the rotation of the shielding component are controlled by the same drive unit, their actions can be better coordinated, simplifying the control logic and improving the reliability and coordination of the control system.

[0007] In one embodiment of the present invention, the two power output ends are a first power output end and a second power output end, the first power output end drives the cleaning mechanism to rise and fall, and the second power output end drives the shielding member to rotate; the power input end drives the first power output end to move, and the first power output end drives the second power output end to move.

[0008] The beneficial effects of this setup are as follows: Since the power input drives the first power output, and the first power output drives the second power output, a hierarchical power transmission can be achieved. Firstly, the placement of the first and second power outputs can be flexibly adjusted according to actual needs, which helps optimize the overall layout of the cleaning equipment and improve space utilization. Secondly, the single power transmission path avoids energy loss caused by branch structures, making power transmission more stable and efficient. Finally, the hierarchical transmission mechanism eliminates the need for complex power distribution and coordination, reducing the system's control difficulty and improving the reliability of the cleaning equipment.

[0009] In one embodiment of the present invention, the power input end includes an input gear, the first power output end includes a first output gear, the second power output end includes a second output gear, the first output gear is drivenly connected to the input gear, and the second output gear is drivenly connected to the first output gear.

[0010] The beneficial effects of this configuration are as follows: This embodiment achieves gear transmission between the power input end and both the first and second power output ends by setting an input gear, a first output gear, and a second output gear, with the first output gear driving the input gear and the second output gear driving the first output gear. This allows for flexible adjustment of the speed, torque, and direction of rotation at both the power input and output ends by adjusting the tooth ratio among the input, first, and second output gears. Therefore, it improves the design flexibility of the transmission mechanism. Furthermore, the gear transmission structure offers advantages such as high transmission efficiency, compact structure, and reliable operation, thus improving the operational accuracy of the transmission mechanism and extending its service life.

[0011] In one embodiment of the present invention, the transmission ratio between the input gear and the first output gear is less than the transmission ratio between the first output gear and the second output gear.

[0012] The beneficial effects of this configuration are as follows: This gear ratio setting allows for progressively slower power reduction during transmission, while simultaneously amplifying torque at each stage. This configuration ensures that the second output end receives a larger torque, thereby more effectively and smoothly driving the shielding component furthest from the input gear. Simultaneously, the smaller gear ratio between the input and first output gear means that the drive component at the power input end can operate at a higher speed while outputting a smaller torque. This operating mode helps reduce mechanical wear on the drive component, thus extending its service life. Furthermore, the smaller torque output also helps reduce the risk of power overload on the drive component, further improving the reliability and stability of the cleaning equipment.

[0013] In one embodiment of the present invention, the first output gear is connected to the input gear via a first gear assembly; the second output gear is connected to the first output gear via a second gear assembly; the transmission ratio between the input gear and the first output gear is 1, and the reduction ratio between the first gear assembly and the second gear assembly is 1.

[0014] The beneficial effects of this configuration are as follows: By setting up the first and second gear assemblies, various flexible combinations of transmission ratios can be achieved by adjusting their transmission ratios. This allows the transmission mechanism to better adapt to the different speed and torque requirements of the first and second output ends, improving the design flexibility of the transmission mechanism. Simultaneously, the gear assemblies can achieve a large transmission ratio and high torque transmission capacity within a small space. Therefore, by rationally designing the size and position of the gear assemblies, complex power transmission can be achieved within a limited space, not only optimizing the overall layout of the cleaning equipment but also improving the flexibility of the placement of the first and second output gears. Furthermore, by setting the transmission ratio between the input gear and the first output gear to 1, and the reduction ratio of the second gear assembly to 1, it means that the presence of the first and second gear assemblies does not change the transmission ratio between the input gear and the first output gear, or between the first output gear and the second output gear. In other words, the first and second gear assemblies primarily function as idlers. This makes setting the transmission ratio in the transmission mechanism more flexible and convenient, and significantly simplifies the calculation process of the entire transmission system. Meanwhile, since the transmission ratio of each stage remains at 1, power transmission will not accumulate errors due to transmission ratio mismatch, thus improving the overall operating accuracy of the transmission mechanism. On the other hand, because the transmission ratio between the input gear and the first output gear is 1, and the reduction ratio of the second gear assembly is also 1, the tooth profiles of these gears can be completely identical. This means that roughly the same gear design and manufacturing process can be used, significantly reducing design and manufacturing costs.

[0015] In one embodiment of the present invention, the lifting mechanism further includes a linkage mechanism, and the first output gear drives the cleaning mechanism to lift through the linkage mechanism; both the linkage mechanism and the transmission mechanism are located on the outer side of the cleaning mechanism along its length direction, and along the length direction of the cleaning mechanism, the projection area of ​​at least one of the linkage mechanism and the transmission mechanism partially overlaps with the projection area of ​​the cleaning mechanism.

[0016] The advantages of this design are twofold: First, the linkage mechanism enables complex motion conversion within a limited space, making it easier to convert the rotational motion of the first output end into the lifting motion of the cleaning mechanism. This facilitates a more compact overall design for the lifting mechanism, making it particularly suitable for cleaning equipment in space-constrained environments. Second, the linkage mechanism can be flexibly arranged according to specific structural requirements, making it easier to install in multiple directions, such as horizontal, vertical, or inclined, thus better adapting to different installation spaces and motion conversion requirements. Furthermore, the main components of the linkage mechanism (such as connecting rods and spherical bearings) are easy to replace and maintain. Compared to hydraulic or electric lifting methods, the linkage mechanism experiences less wear and is easier to maintain. By placing the linkage mechanism and transmission mechanism on the outside of the cleaning mechanism along its length, rather than directly above it, the space occupied above the cleaning mechanism is effectively reduced, lowering the overall height of the cleaning equipment. This allows the cleaning equipment to better adapt to height-constrained cleaning scenarios, such as cleaning work in narrow passages or low spaces. Meanwhile, placing the linkage mechanism and transmission mechanism on the outside of the cleaning mechanism helps maintain the balance of the cleaning equipment's center of gravity, which can reduce swaying or instability caused by the shift of the center of gravity during cleaning operations, thereby improving the stability of the cleaning equipment's operation.

[0017] In one embodiment of the present invention, the linkage mechanism includes a first link and a sliding member. One end of the first link is fixedly connected to a first output gear, and the other end is rotatably connected to the sliding member, which is slidably connected to the machine body.

[0018] The advantages of this design are as follows: By incorporating a first connecting rod and a sliding component, the rotation of the first connecting rod in conjunction with the sliding of the sliding component can convert the rotational motion of the first output gear into the lifting motion of the cleaning mechanism. This motion conversion method not only meets the lifting requirements of the cleaning mechanism but also allows for flexible control of the lifting stroke by adjusting the length of the first connecting rod or the installation position of the sliding component. This enhances the design flexibility of the lifting mechanism and its adaptability to different working conditions. Furthermore, the simple structure and small number of parts of the first connecting rod and sliding component result in a more compact overall structure of the lifting mechanism, facilitating installation and maintenance, and improving the operational reliability and economy of the lifting mechanism.

[0019] In one embodiment of the present invention, the linkage mechanism includes a first link, a sliding member, and a second link. The second link is fixedly connected to the machine body and is provided with a sliding groove. One end of the first link is fixedly connected to a first output gear, and the other end is rotatably connected to the sliding member. The sliding member slides along the sliding groove. The sliding direction of the sliding member relative to the machine body is parallel to the traveling direction of the cleaning equipment.

[0020] The advantages of this design are as follows: By adding a second connecting rod and incorporating a groove on it, the second connecting rod can be more flexibly adjusted in position on the machine body to correspond with the groove's position. This flexibility allows the linkage mechanism to better adapt to machine body structures of different sizes and shapes, as well as varying installation space requirements. Furthermore, when the groove experiences significant wear, the second connecting rod can be directly replaced without altering the machine body's mounting structure, thus facilitating future replacement and maintenance. The sliding direction of the sliding component relative to the machine body is parallel to the cleaning equipment's travel direction. This makes positioning and installation of the groove and machine body more convenient and intuitive, reducing motion errors caused by assembly deviations. Additionally, it simplifies the calculation of lifting and sliding strokes, reducing computational complexity and improving the control accuracy of the linkage mechanism's trajectory.

[0021] In one embodiment of the present invention, the rotational speed of the first output gear is greater than that of the second output gear; the first connecting rod includes a rod body and a connecting part, one end of the rod body is rotatably connected to a sliding member, and the other end is connected to the connecting part through a sliding assembly; the connecting part is fixedly connected to the first output gear; during the rotation of the first output gear, after the connecting part rotates with the first output gear to a preset angle, the sliding assembly drives the rod body to rotate synchronously.

[0022] The beneficial effects of this design are as follows: Since the rotational speed of the first output gear is greater than that of the second output gear, a phase difference will inevitably occur between them during rotation. Without control, this phase difference will cause the lifting and lowering operation of the cleaning mechanism and the rotation of the shielding component to be out of sync, thus affecting the normal operation of the cleaning equipment. In this embodiment, by setting a sliding component between the rod body and the connecting part, when the first output gear rotates, the connecting part first rotates with the first output gear to a preset angle, and then drives the rod body to rotate synchronously through the sliding component. This design allows the connecting part to rotate independently in the initial stage of the first output gear's rotation, while the rod body remains stationary, thus providing a buffer space for the phase difference. After the connecting part rotates to the preset angle, it again drives the rod body to rotate synchronously through the sliding component. In this way, in the final stage of the lifting and lowering operation, the lifting and lowering action of the cleaning mechanism and the rotation of the shielding component can be synchronized, thereby ensuring the normal cleaning operation of the cleaning equipment.

[0023] In one embodiment of the present invention, the sliding component includes an arc-shaped groove and a protrusion. One of the arc-shaped groove and the protrusion is disposed on the rod body and the other is disposed on the connecting part. The protrusion slides along the arc-shaped groove, and the rotation axis of the arc-shaped groove coincides with the rotation axis of the first output gear.

[0024] The beneficial effects of this design are as follows: By configuring the sliding component as an arc-shaped groove and a protrusion structure, on the one hand, the protrusion slides along the arc-shaped groove, forming a stable guiding structure. This ensures that the relative motion trajectory between the rod body and the connecting part is precisely controllable, thereby reducing the probability of deviation or wobbling between the two during movement. On the other hand, since the rotation axis of the arc-shaped groove coincides with the rotation axis of the first output gear, the motion trajectory of the sliding component is consistent with the rotational motion of the first output gear, which further improves the stability and accuracy of operation.

[0025] In one embodiment of this utility model, two sets of linkage mechanisms are provided, and the two sets of linkage mechanisms are respectively arranged on both sides of the outer side of the cleaning mechanism along its length. The two sets of linkage mechanisms are connected by a synchronization mechanism. When the first output gear rotates, the synchronization mechanism can realize the synchronous operation of the two sets of linkage mechanisms. The synchronization mechanism includes a drive shaft and a support base. The support base is rotatably connected to the end of the cleaning mechanism away from the first output gear, and the two ends of the drive shaft are respectively fixedly connected to the support base and the first output gear. One set of the two linkage mechanisms is fixedly connected to the first output gear, and the other set is fixedly connected to the support base.

[0026] The beneficial effects of this configuration are as follows: By arranging two sets of linkage mechanisms on the outer sides of the cleaning mechanism along its length, a dual-sided synchronous drive structure can be formed. This structure allows the lifting and lowering motion of the cleaning mechanism to be completed jointly by the linkage mechanisms on both sides, thereby achieving a uniform distribution of force during the lifting and lowering process. Compared with a single-sided drive scheme, the dual-sided synchronous drive structure can effectively avoid the risk of uneven load and prevent problems such as shaking or movement jamming caused by uneven force, thus improving the smoothness and accuracy of the lifting and lowering operation of the cleaning mechanism. In addition, since the dual-sided synchronous drive structure can form a dual-sided support structure on both sides of the cleaning mechanism along its length, it can enhance the overall rigidity and load-bearing capacity of the cleaning mechanism. This not only helps to enhance the cleaning mechanism's ability to withstand the loads and impacts generated during cleaning operations, but also effectively extends the service life of the cleaning equipment. By setting up a drive shaft and a support base, when the first output gear rotates, part of its power is transmitted to the corresponding linkage mechanism, driving the linkage mechanism to move. The other part of the power can be transmitted through the drive shaft to the support base, and then the support base drives the linkage mechanism on the corresponding side to run, thereby achieving synchronous operation of the linkage mechanisms on both sides. Since the two ends of the drive shaft are fixedly connected to the support base and the first output gear respectively, a rigid connection structure can be formed. This structure ensures that the power of the first output gear can be directly transmitted to the support base through the drive shaft, thereby driving the two sets of linkage mechanisms to move synchronously. This avoids the elastic deformation or slippage that may occur with flexible connections (such as belts and chains), which is beneficial to ensuring the accuracy of synchronous transmission.

[0027] In one embodiment of the present invention, the cleaning mechanism includes: a bracket and a support assembly. The bracket is connected to a lifting mechanism and has a receiving cavity. The receiving cavity has an opening facing the surface to be cleaned. The support assembly is rotatably installed in the receiving cavity, and a cleaning component is wound around the outer periphery of the support assembly. A blocking component is rotatably installed on the bracket and disposed on the outer periphery of the receiving cavity. The cleaning component is a mop. In a first rotation position, the blocking component closes the opening. In a second rotation position, the blocking component opens the opening.

[0028] The beneficial effects of this design are as follows: When the blocking element is in its first rotating position, the opening is closed, sealing the cleaning component within the receiving cavity. This improves the isolation effect between the cleaning component and the surface to be cleaned, further reducing the probability of dust, stains, or water droplets from the cleaning component dripping onto the surface, thus effectively minimizing carpet contamination. When the blocking element is in its second rotating position, the opening is opened, fully exposing the cleaning component and allowing it to contact the surface to be cleaned. This design ensures that the blocking element does not interfere with the normal operation of the cleaning component, thereby effectively guaranteeing cleaning efficiency and quality.

[0029] In one embodiment of the present invention, a scraper is provided near the opening of the bracket. The scraper is located on the rear side of the forward direction of the cleaning device and can abut against the surface to be cleaned when the cleaning mechanism is in the lowered position. When the blocking member closes the opening, the blocking member abuts against the scraper and causes the scraper to bend toward the rear side of the forward direction of the cleaning device.

[0030] The advantages of this design are as follows: Because the shielding element allows the squeegee to bend backwards in the direction of the cleaning device's movement, the squeegee is further away from the surface to be cleaned in the vertical direction. This reduces the likelihood of the squeegee coming into contact with the carpet, thus minimizing the risk of carpet contamination. Simultaneously, this design prevents gaps from forming between the shielding element and the squeegee when the opening is closed. This reduces the probability of stains or water from the cleaning device dripping onto the carpet through these gaps, further reducing the likelihood of carpet contamination.

[0031] In one embodiment of the present invention, the cleaning mechanism has at least a raised position and a lowered position during the lifting and lowering movement. In the raised position, the cleaning component is lifted away from the surface to be cleaned; in the lowered position, the cleaning component contacts the surface to be cleaned; when the cleaning mechanism is in the raised position, the blocking component rotates to the first rotation position; when the cleaning mechanism is in the lowered position, the blocking component rotates to the second rotation position.

[0032] The advantages of this design are: it allows for coordinated control of the lifting and lowering movements of the cleaning mechanism and the rotation of the shielding components, thereby ensuring greater efficiency and reliability in cleaning operations. Simultaneously, when the cleaning component is lifted away from the surface to be cleaned, the shielding components effectively isolate the component from the surface, preventing dust, stains, or other contaminants from the component from falling onto the surface, thus significantly reducing the risk of contaminating the carpet or other surfaces awaiting cleaning.

[0033] In one embodiment of the present invention, the cleaning device further includes a first detection component and a second detection component. The first detection component is used to detect whether the cleaning mechanism is in a raised position and whether the shielding member is in a first rotation position. The second detection component is used to detect whether the cleaning mechanism is in a lowered position and whether the shielding member is in a second rotation position.

[0034] The advantages of this design are as follows: By integrating the detection of the lifting position of the cleaning mechanism and the rotation position of the blocking component into the same detection assembly, it is possible to avoid setting up separate detection assemblies for the lifting operation of the cleaning mechanism and the rotation operation of the blocking component. This integrated design not only effectively reduces the total number of detection assemblies and simplifies the overall number of parts, but also helps to reduce manufacturing costs. At the same time, the integrated detection assembly can simultaneously acquire the position status of the cleaning mechanism and the blocking component, reducing the number of signal acquisition and processing steps, thereby improving detection efficiency and the response speed of the control system, which is conducive to achieving more precise motion control.

Detailed Implementation

[0068] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0069] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. The drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0070] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the present invention. However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the present invention.

[0071] Please see Figures 1 to 29 This utility model provides a cleaning device 100. The cleaning device 100 is equipped with a lifting mechanism 120, which controls the lifting of the cleaning mechanism 130, thereby physically blocking the cleaning component 131 from the carpet in the height direction, reducing the contamination of the carpet by the cleaning component 131. In addition, the cleaning device 100 also has a rotatable shielding component 140. By switching between a first rotation position and a second rotation position, the cleaning component 131 can be isolated from or come into contact with the surface 190 to be cleaned. When the cleaning component 131 encounters the carpet, controlling the rotation of the shielding component 140 can isolate the cleaning component 131 from the carpet, further reducing the contamination of the carpet by the cleaning component 131, especially effectively reducing the risk of wastewater dripping from the cleaning component 131 onto the carpet in a wet state, causing contamination.

[0072] Please see Figure 1 , Figure 4 and Figure 5 The cleaning device 100 includes: a body 110, a lifting mechanism 120, a cleaning mechanism 130, and a shielding component 140. The cleaning device 100 can be any self-propelled mopping device 100, such as a floor scrubber, sweeper, or cleaning robot. For ease of description, this application uses a cleaning robot as an example.

[0073] The interior of the body 110 has a storage space to accommodate various components of the cleaning device 100. The shape of the body 110 can be arbitrary, such as circular, elliptical, or D-shaped. The cleaning device 100 also includes a drive assembly conventionally provided on existing cleaning devices 100. The drive assembly is located below the body 110 to drive the cleaning device 100 to achieve self-movement. The specific structure of the drive assembly and the connection structure between the drive assembly and the body 110 can be found in the relevant structural descriptions of existing cleaning devices 100, and will not be repeated here.

[0074] The lifting mechanism 120 is connected to the machine body 110, and the cleaning mechanism 130 is connected to the lifting mechanism 120. Driven by the lifting mechanism 120, the cleaning mechanism 130 moves up and down relative to the machine body 110. It should be noted that the cleaning mechanism 130 has at least a raised position and a lowered position during its lifting operation. When in the raised position, the cleaning mechanism 130 lifts away from the surface to be cleaned 190, and the cleaning component 131 also lifts away from the surface to be cleaned 190, thereby stopping the cleaning operation on the surface to be cleaned 190. When in the lowered position, the cleaning mechanism 130 approaches the surface to be cleaned 190, allowing the cleaning component 131 to contact the surface to be cleaned 190, thus completing the cleaning operation on the surface to be cleaned 190. In this embodiment, the type and structure of the lifting structure are not limited, including but not limited to linkage mechanisms, actuators, and pulley lifting assemblies.

[0075] The specific structure of the cleaning mechanism 130 is not limited; for example, it can be a disc-shaped wiping cloth structure, a roller-shaped wiping cloth structure, a conveyor belt wiping cloth structure, etc., as long as it can meet the cleaning requirements of the surface 190 to be cleaned. The cleaning mechanism 130 includes a cleaning component 131, which is used to clean the surface 190 to be cleaned. The cleaning component 131 can be configured for wet cleaning or dry cleaning, and this embodiment does not limit this.

[0076] Optionally, in one embodiment, the cleaning device 100 may further include a side brush and a roller brush, both located at the bottom of the body 110. Along the traveling direction of the body 110, both the side brush and the roller brush are positioned in front of the cleaning mechanism 130. The side brush may be located at the edge of the body 110 and can rotate via a rotating mechanism, which may be a combination of a motor and a reducer. When the side brush rotates, it gathers debris from the edge of the body 110 towards the inside of the body 110, thereby increasing the cleaning range of the cleaning device 100. The side brush may be a rubber strip or a bristle brush, as long as it can clean the ground; there are no limitations. The roller brush is rotatably disposed within a roller brush cavity at the bottom of the body 110. During its rotation, the roller brush can sweep away debris on the ground. The number of roller brushes can be set according to specific requirements; there are no limitations in this embodiment.

[0077] Along the traveling direction of the machine body 110, the side brush and roller brush are positioned in front of the cleaning mechanism 130. This facilitates the cleaning operation of the cleaning equipment 100, which involves dry sweeping followed by wet mopping. This improves the cleaning effect and efficiency, and also facilitates the layout of the internal space of the machine body 110.

[0078] In addition, the cleaning equipment 100 may also include a sensing system and a control system. The sensing system and the control system are electrically connected. The sensing system includes an LDS located on top of the fuselage 110, a buffer and vision sensor located at the front of the fuselage 110, and an edge sensor located on the front side wall of the fuselage 110. Among them, the LDS, buffer, and edge sensor can all measure or sense distance to obtain the distance between the edge of the fuselage 110 and the obstacle. The control system controls the cleaning equipment 100 to perform corresponding actions based on this distance. For example, it controls the cleaning equipment 100 to perform obstacle avoidance, edge cleaning, and return to the base station.

[0079] The shielding member 140 is rotatably mounted on the cleaning mechanism 130 and partially shields the outer periphery of the cleaning member 131. There are various possible rotatable mounting methods; for example, the shielding member 140 can be directly rotatably connected to the cleaning mechanism 130 via a rotating shaft, or it can be indirectly rotatably connected to the cleaning mechanism 130 via other transmission components (gear assembly, worm gear assembly). The shielding member 140 has a first rotating position and a second rotating position.

[0080] like Figure 6 and Figure 7 As shown, in the first rotation position, the shield 140 is along the height direction of the cleaning mechanism 130 (e.g., Figure 7 (As shown in the Z-axis direction) is located between the surface to be cleaned 190 and the cleaning component 131 to isolate the cleaning component 131 from the surface to be cleaned 190. For example... Figure 4 and Figure 5 As shown, in the second rotation position, the shield 140 rotates away from the position between the surface to be cleaned 190 and the cleaning member 131, so that the cleaning member 131 can contact the surface to be cleaned 190 along the height direction of the cleaning device 100.

[0081] The cleaning component 131 is prone to carrying dirt during the cleaning process. When the cleaning mechanism 130 passes over the carpet, even if the cleaning component 131 is lifted by the lifting mechanism 120, the long-pile carpet may still cause the cleaning component 131 to come into contact with the carpet; in addition, if the cleaning component 131 is used for wet cleaning, wastewater may still drip onto the carpet after being lifted. In both of these cases, simply lifting the cleaning component 131 in the vertical direction is not enough to effectively prevent the carpet from becoming contaminated.

[0082] In this embodiment, by providing a shielding member 140, when the shielding member 140 is in the first rotation position, it can isolate the cleaning member 131 from the surface to be cleaned 190. Therefore, this further reduces the probability of dust, stains, or water droplets on the cleaning member 131 dripping onto the surface to be cleaned 190, thereby effectively reducing the contamination of the carpet by the cleaning member 131. When the shielding member 140 is in the second rotation position, it can rotate away from the position between the surface to be cleaned 190 and the cleaning member 131, allowing the cleaning member 131 to be fully exposed and in contact with the surface to be cleaned 190. This ensures that the shielding member 140 does not interfere with the normal operation of the cleaning member, thereby effectively guaranteeing cleaning efficiency and quality.

[0083] Please see Figure 9 and Figure 11 The lifting mechanism 120 includes a drive component 121 and a transmission mechanism 122. The transmission mechanism 122 includes a power input end 123 and two power output ends. The drive component 121 drives the two power output ends through the power input end 123. The drive component 121 can be any device capable of generating power, such as a motor, a combination of a motor and a reducer, or a hydraulic motor. Specifically, the power input end 123 is connected to the output end of the drive component 121 to receive power from the drive component 121 and transmit the power to the two power output ends. The connection method between the power input end 123 and the output end of the drive component 121 is not limited; for example, it can be a direct connection or an indirect connection through common transmission mechanisms such as chain drive, belt drive, or gear drive. One of the two power output ends is connected to the cleaning mechanism 130 and transmits power to the cleaning mechanism 130 to drive the cleaning mechanism 130 to move up and down between the raised and lowered positions. The other of the two power output terminals is connected to the shield 140 and transmits power to the shield 140 to drive the shield 140 to rotate between the first rotation position and the second rotation position.

[0084] In this embodiment, the cleaning device 100 is provided with a lifting mechanism 120, which can drive the cleaning mechanism 130 to move up and down. By controlling the lifting and lowering of the cleaning mechanism 130, the cleaning component 131 can remain separated from the surface to be cleaned 190 in the height direction of the cleaning device 100. When the cleaning device 100 passes over the carpet, this separation can achieve physical isolation between the cleaning component 131 and the carpet, thereby reducing the probability of the cleaning component 131 coming into contact with the carpet, and thus reducing the possibility of residual stains or moisture on the cleaning component 131 contaminating the carpet. In addition, the cleaning device 100 is also provided with a rotatable shielding component 140. The shielding component 140 can switch between a first rotation position and a second rotation position, thereby achieving isolation or contact between the cleaning component 131 and the surface to be cleaned 190. When the cleaning device 100 passes over the carpet, the shielding component 140 can be rotated to the first rotation position. At this time, the shielding member 140 is located between the carpet and the cleaning member 131, which can further block the contact path between the cleaning member 131 and the carpet, thereby further reducing the probability that the stains or moisture remaining on the cleaning member 131 will contaminate the carpet.

[0085] Furthermore, this embodiment reduces the number of drive components 121 used by sharing a single drive component 121 to drive the lifting and lowering of the cleaning mechanism 130 and the rotation of the shielding component 140. This design not only reduces the manufacturing cost of the cleaning equipment 100 but also saves installation space in the body 110, facilitating a compact structural design for the cleaning equipment 100. Meanwhile, in the design of the cleaning mechanism 130, the coverage area of ​​the cleaning surface needs to be fully considered, therefore the cleaning mechanism 130 typically requires a large extension dimension in the width direction. At the same time, the drive component 121 used for lifting and lowering generally needs to be arranged along the height direction of the cleaning mechanism 130. If too many drive components 121 are used, too much height space in the cleaning mechanism 130 will be occupied, resulting in a significant reduction in the height space of the body 110 of the cleaning equipment 100. Therefore, adopting the scheme of sharing a single drive component 121 in this embodiment facilitates a compact structural design of the cleaning equipment 100 in terms of height space, making it easier for the cleaning equipment 100 to perform cleaning operations in height-restricted scenarios. Meanwhile, since the lifting of the cleaning mechanism 130 and the rotation of the shielding member 140 are controlled by the same drive member 121, their actions can be better coordinated, which helps to simplify the control logic and improve the reliability and coordination of the control system.

[0086] In one embodiment of this utility model, please refer to Figure 7 When the cleaning mechanism 130 is in the raised position, the blocking member 140 rotates to the first rotation position. At this time, the cleaning member 131 is lifted away from the surface to be cleaned 190, the cleaning operation stops, and the blocking member 140 is positioned between the surface to be cleaned 190 and the cleaning member 131, isolating the cleaning member 131 from the surface to be cleaned 190. Please refer to [link / reference]. Figure 5 When the cleaning mechanism 130 is in the lowered position, the shielding member 140 rotates to the second rotation position. At this time, the cleaning member 131 contacts the surface to be cleaned 190 to perform the cleaning operation, and the shielding member 140 moves away from the position between the surface to be cleaned 190 and the cleaning member 131, so that the cleaning member 131 can fully contact the surface to be cleaned 190.

[0087] This configuration allows for coordinated control of the lifting and lowering movement of the cleaning mechanism 130 and the rotation of the blocking component 140, thereby ensuring greater efficiency and reliability of the cleaning operation. Simultaneously, when the cleaning component 131 is lifted away from the surface 190 to be cleaned, the blocking component 140 can promptly isolate the cleaning component 131 from the surface 190, preventing dust, stains, or other contaminants on the cleaning component 131 from falling onto the surface 190, thus effectively reducing the risk of contamination to the carpet or the surface 190 to be cleaned.

[0088] In one embodiment, the lifting and lowering movement of the cleaning mechanism 130 and the rotation of the shielding member 140 can be completely synchronized. Specifically, when the cleaning mechanism 130 starts to lift and lower, the shielding member 140 rotates synchronously; when the cleaning mechanism 130 stops lifting and lowering, the shielding member 140 stops rotating synchronously.

[0089] In another embodiment, the lifting and lowering of the cleaning mechanism 130 and the rotation of the shielding member 140 may operate synchronously for part of a time period and asynchronously for part of a time period. For example, in the initial stage of the operation of the drive member 121, the rotation of the shielding member 140 may precede the lifting and lowering of the cleaning mechanism 130, and in the subsequent time period, the rotation of the shielding member 140 will be synchronized with the lifting and lowering of the cleaning mechanism 130.

[0090] Please participate Figure 11 and Figure 12 In one embodiment of this utility model, the two power output terminals are a first power output terminal 124 and a second power output terminal 125, respectively. The first power output terminal 124 drives the cleaning mechanism 130 to rise and fall, and the second power output terminal 125 drives the shielding member 140 to rotate. The power input terminal 123 drives the first power output terminal 124 to operate, and the first power output terminal 124 drives the second power output terminal 125 to operate.

[0091] In this embodiment, since the power input terminal 123 drives the first power output terminal 124, and the first power output terminal 124 drives the second power output terminal 125, a hierarchical power transmission can be achieved. Using this hierarchical transmission method, firstly, the arrangement of the first power output terminal 124 and the second power output terminal 125 can be flexibly adjusted according to actual needs, which is beneficial for optimizing the overall layout of the cleaning equipment 100 and improving space utilization; secondly, the single power transmission path avoids energy loss caused by branch structures, making power transmission more stable and efficient; finally, the hierarchical transmission mechanism eliminates the need for complex power distribution coordination, reducing the control difficulty of the system and improving the reliability of the cleaning equipment 100's operation.

[0092] In this invention, the specific structural forms of the power input end 123, the first power output end 124, and the second power output end 125 are not limited. For example, they can be a shaft structure, a gear structure, a transmission belt structure, etc. Optionally, please refer to... Figure 12 In one embodiment of this utility model, the power input end 123 includes an input gear 1231, which is connected to the output end of the drive member 121. The drive member 121 drives the input gear 1231 to rotate. The first power output end 124 includes a first output gear 1241, and the second power output end 125 includes a second output gear 1251. The first output gear 1241 is installed between the input gear 1231 and the second output gear 1251. The first output gear 1241 is drive-connected to the input gear 1231, and the second output gear 1251 is drive-connected to the first output gear 1241.

[0093] It should be noted that the transmission connection between the first output gear 1241 and the input gear 1231 can be a direct gear meshing transmission connection or an indirect transmission connection achieved through other additional gear assemblies. Similarly, the transmission connection between the second output gear 1251 and the first output gear 1241 can also be a direct gear meshing transmission connection or an indirect transmission connection achieved through other additional gear assemblies. For details, please refer to [link to relevant documentation]. Figure 10 and Figure 12The cleaning mechanism 130 includes a bracket 132, which has a gear mounting cavity 1323. The bracket 132 is fixedly connected to the body 110 via a lifting mechanism 120. The input gear 1231, the first output gear 1241, and the second output gear 1251 are all rotatably connected to the bracket 132 and housed within the gear mounting cavity 1323. By providing the gear mounting cavity 1323, the risk of dust, particles, and other impurities entering the gear meshing area during cleaning operations can be effectively reduced, thereby reducing the possibility of gear wear or jamming and extending the service life of the gear assembly. Of course, in other embodiments, the bracket 132 may not have a gear mounting cavity 1323, and the input gear 1231, the first output gear 1241, and the second output gear 1251 may be exposed to the outside of the cleaning mechanism 130.

[0094] This embodiment achieves gear transmission between the power input end 123 and the first and second power output ends 124 and 125 by setting an input gear 1231, a first output gear 1241, and a second output gear 1251, with the first output gear 1241 drivingly connected to the input gear 1231 and the second output gear 1251 drivingly connected to the first output gear 1241. Thus, by adjusting the tooth ratio among the input gear 1231, the first output gear 1241, and the second output gear 1251, the speed, torque, and direction of rotation of the power input end 123 and the power output end can be flexibly adjusted. Therefore, it is more conducive to improving the design flexibility of the transmission mechanism 122. At the same time, the gear transmission structure also has advantages such as high transmission efficiency, compact structure, and reliable operation, thus helping to improve the operating accuracy of the transmission mechanism 122 and extend its service life.

[0095] Please see Figure 12 In one embodiment of the present invention, the transmission ratio between the input gear 1231 and the first output gear 1241 is less than the transmission ratio between the first output gear 1241 and the second output gear 1251.

[0096] In this embodiment, the transmission ratio between the input gear 1231 and the first output gear 1241 is smaller than the transmission ratio between the first output gear 1241 and the second output gear 1251. This transmission ratio setting allows for gradual deceleration of power during transmission, while simultaneously amplifying torque at each stage. This configuration ensures that the second output gear 1251 receives a larger torque, thereby more effectively driving the shielding member 140, located away from the input gear 1231, to rotate smoothly. Simultaneously, the smaller transmission ratio between the input gear 1231 and the first output gear 1241 means that the drive member 121 at the power input end 123 can operate at a higher speed while outputting a smaller torque. This operating mode helps reduce mechanical wear on the drive member 121, thus extending its service life. Furthermore, the smaller torque output also helps reduce the risk of power overload on the drive member 121, further improving the reliability and stability of the cleaning equipment 100.

[0097] Please see Figure 12 In one embodiment of this utility model, the first output gear 1241 is connected to the input gear 1231 via a first gear assembly 126. The second output gear 1251 is connected to the first output gear 1241 via a second gear assembly 127. The number of gears in the first gear assembly 126 and the second gear assembly 127 may be equal or unequal.

[0098] Optionally, please refer to Figure 12 In this embodiment, the first gear assembly 126 has one gear, which is designated as the first transmission gear 1261 for ease of description. The input gear 1231 meshes with the first transmission gear 1261, and the first transmission gear 1261 meshes with the first output gear 1241. The second gear assembly 127 has two gears. For ease of description, these two gears are designated as the second transmission gear 1271 and the third transmission gear 1272, respectively. The first output gear 1241 meshes with the second transmission gear 1271, the second transmission gear 1271 meshes with the third transmission gear 1272, and the third transmission gear 1272 meshes with the second output gear 1251. The number of teeth among the first transmission gear 1261, the second transmission gear 1271, and the third transmission gear 1272 can be equal or unequal, depending on factors such as the output speed and output torque of the first output gear 1241 and the second output gear 1251.

[0099] In the above embodiments, by setting the first gear assembly 126 and the second gear assembly 127, a variety of flexible combinations of transmission ratios can be achieved by adjusting the transmission ratio of the first gear assembly 126 and the second gear assembly 127. This allows the transmission mechanism 122 to better adapt to the different speed and torque requirements between the first output gear 1241 and the second output gear 1251, which is beneficial to improving the design flexibility of the transmission mechanism 122. At the same time, the gear assembly can achieve a large transmission ratio and high torque transmission capacity in a small space. Therefore, by reasonably designing the size and position of the gear assembly, complex power transmission can be achieved in a limited space, which not only optimizes the overall layout of the cleaning equipment 100, but also improves the flexibility of the setting position of the first output gear 1241 and the second output gear 1251.

[0100] Please see Figure 12 In one embodiment of this utility model, the transmission ratio between the input gear 1231 and the first output gear 1241 is 1, and the reduction ratio of the second gear assembly 127 is 1. The transmission ratio of the input gear 1231 to the first output gear 1241 being 1 indicates that the number of teeth among the input gear 1231, the first transmission gear 1261, and the first output gear 1241 is equal. The reduction ratio of the second gear assembly 127 being 1 indicates that the number of teeth among the second transmission gear 1271 and the third transmission gear 1272 is equal.

[0101] This configuration means, on the one hand, that the presence of the first gear assembly 126 and the second gear assembly 127 does not change the transmission ratio between the input gear 1231 and the first output gear 1241, or between the first output gear 1241 and the second output gear 1251. In other words, the first gear assembly 126 and the second gear assembly 127 primarily function as idlers. This makes the setting of the transmission ratio in the transmission mechanism 122 more flexible and convenient, and significantly simplifies the calculation process of the entire transmission system. Simultaneously, since the transmission ratio of each stage remains at 1, power transmission will not accumulate errors due to transmission ratio mismatch, thus improving the overall operating accuracy of the transmission mechanism 122. On the other hand, since the transmission ratio between the input gear 1231 and the first output gear 1241 is 1, and the reduction ratio of the second gear assembly 127 is also 1, the tooth profiles of these gears can be completely identical. This means that roughly the same gear design and manufacturing process can be used, thereby significantly reducing design and manufacturing costs.

[0102] Although this utility model does not limit the specific structural form of the lifting mechanism 120, alternatively, please refer to Figure 11 and Figure 13In one embodiment of this utility model, the lifting mechanism 120 further includes a linkage mechanism 128, through which the first output gear 1241 drives the cleaning mechanism 130 to move up and down. Specifically, see [reference needed]. Figure 4 and Figure 13 The input end of the linkage mechanism 128 is connected to the first output gear 1241, and the output end of the linkage mechanism 128 is connected to the machine body 110. The operation of the first output gear 1241 drives the linkage mechanism 128 to operate, and the operation of the linkage mechanism 128 drives the cleaning mechanism 130 to rise and fall relative to the machine body 110.

[0103] The location of the linkage mechanism 128 is not limited; for example, it can be located at the height of the cleaning mechanism 130 (e.g., ...). Figure 7 Above the Z-axis (as shown), or it can be positioned along the length of the cleaning mechanism 130 (as shown). Figure 9 The linkage mechanism 128 can be located on the side (as shown in the X-axis direction) or at other positions that meet the lifting and lowering requirements. Depending on actual needs, one or more linkage mechanisms 128 can be provided. The specific structural type of the linkage mechanism 128 can be varied; for example, it can be a double-link mechanism, a crank-slider mechanism, a multi-link combination mechanism, a gear and linkage combination mechanism, etc. The specific selection needs to be optimized based on the lifting and lowering requirements and spatial layout of the cleaning mechanism 130.

[0104] In this embodiment, the lifting mechanism 120 adopts a linkage mechanism 128. This arrangement allows the linkage mechanism 128 to achieve complex motion conversions within a limited space, making it easier to convert the rotational motion of the first output gear 1241 into the lifting motion of the cleaning mechanism 130. This facilitates a more compact overall design for the lifting mechanism 120, making it particularly suitable for cleaning equipment 100 in space-constrained environments. Furthermore, the linkage mechanism 128 can be flexibly arranged according to specific structural requirements, making it easier to install in multiple directions such as horizontal, vertical, or inclined, thus better adapting to different installation spaces and motion conversion requirements. Additionally, the main components of the linkage mechanism 128 (such as connecting rods and spherical bearings) are easy to replace and maintain. Compared to hydraulic or electric lifting methods, the linkage mechanism 128 experiences less wear and is easier to maintain.

[0105] Please see Figure 9 and Figure 13In one embodiment of this utility model, both the linkage mechanism 128 and the transmission mechanism 122 are disposed on the outer side of the cleaning mechanism 130 along its length direction, and the projection area of ​​at least one of the linkage mechanism 128 and the transmission mechanism 122 partially overlaps with the projection area of ​​the cleaning mechanism 130 along its length direction. In one embodiment, only the projection area of ​​the linkage mechanism 128 may partially overlap with the projection area of ​​the cleaning mechanism 130 along its length direction. In another embodiment, only the projection area of ​​the transmission mechanism 122 may partially overlap with the projection area of ​​the cleaning mechanism 130 along its length direction. In other embodiments, both the projection areas of the linkage mechanism 128 and the transmission mechanism 122 may partially overlap with the projection area of ​​the cleaning mechanism 130 along its length direction.

[0106] In this embodiment, by placing the linkage mechanism 128 and the transmission mechanism 122 on the outer side of the cleaning mechanism 130 along its length, rather than directly above it, the space occupied above the cleaning mechanism 130 can be effectively reduced, lowering the overall height of the cleaning device 100. This allows the cleaning device 100 to better adapt to height-restricted cleaning scenarios, such as cleaning work in narrow passages or low spaces. Simultaneously, placing the linkage mechanism 128 and the transmission mechanism 122 on the outer side of the cleaning mechanism 130 along its length helps maintain the center of gravity balance of the cleaning device 100, reducing swaying or instability caused by center of gravity shift during cleaning operations, thereby improving the operational stability of the cleaning device 100.

[0107] In one embodiment of this utility model, the linkage mechanism 128 includes a first link 1281 and a slider 1282. Along the length of the first link 1281, one end of the first link 1281 is fixedly connected to a first output gear 1241. The method of fixed connection is not limited; for example, the first output gear 1241 can be a gear shaft structure, and the first link 1281 can be fixedly connected to the gear shaft, thereby achieving a fixed connection with the first output gear 1241. Alternatively, the first output gear 1241 can be fixedly connected to a mounting shaft, and the first link 1281 can be fixedly mounted on the mounting shaft, thereby achieving a fixed connection with the first output gear 1241. The other end of the first link 1281 is rotatably connected to the slider 1282, and the slider 1282 is slidably connected to the body 110. The slider 1282 can take various shapes, as long as it can achieve a rotatable connection with the first link 1281. For example, the slider 1282 can be a bearing, a roller, etc. Optionally, in this embodiment, the slider 1282 is a bearing. The specific ways in which the slider 1282 is slidably connected to the body 110 include, but are not limited to, providing a groove on the body 110, and slidingly installing the slider 1282 in the groove, thereby realizing the sliding connection between the slider 1282 and the body 110.

[0108] In the above embodiments, by setting a first connecting rod 1281 and a sliding member 1282, the rotation of the first connecting rod 1281 and the sliding of the sliding member 1282 can be combined to convert the rotational motion of the first output gear 1241 into the lifting motion of the cleaning mechanism 130. This motion conversion method not only meets the lifting requirements of the cleaning mechanism 130, but also allows for flexible control of the lifting stroke of the cleaning mechanism 130 by adjusting the length of the first connecting rod 1281 or the installation position of the sliding member 1282. This improves the design flexibility of the lifting mechanism 120 and its adaptability to different working conditions. Furthermore, due to the simple structure and small number of parts of the first connecting rod 1281 and the sliding member 1282, the overall structure of the lifting mechanism 120 is more compact, facilitating installation and maintenance, and improving the operational reliability and economy of the lifting mechanism 120.

[0109] To facilitate the installation between the linkage mechanism 128 and the body 110, optionally, please refer to Figure 4 , Figure 10 , Figure 13 and Figure 14In one embodiment of this utility model, the linkage mechanism 128 includes a first link 1281, a sliding member 1282, and a second link 1283. The second link 1283 is fixedly connected to the body 110, and the fixed connection method can be a snap-fit ​​connection, a bolt connection, etc. Optionally, in this embodiment, the body 110 is provided with a slot, which matches the outer contour of the second link 1283, and the second link 1283 is snap-fitted into the slot, thereby realizing the snap-fit ​​fixed connection between the second link 1283 and the body 110. The second link 1283 is provided with a sliding groove 12831.

[0110] Along the length of the first connecting rod 1281, one end of the first connecting rod 1281 is fixedly connected to the first output gear 1241, and the other end of the first connecting rod 1281 is rotatably connected to the sliding member 1282. The sliding member 1282 is disposed in the sliding groove 12831 and slides along the extending direction of the sliding groove 12831. It should be noted that, in this embodiment, the structural form of the sliding member 1282 and the fixed connection method between the first connecting rod 1281 and the first output gear 1241 can be referred to the relevant descriptions in the above embodiments, and will not be repeated here.

[0111] In this embodiment, by adding a second connecting rod 1283 and providing a sliding groove 12831 on the second connecting rod 1283, the position of the second connecting rod 1283 on the fuselage 110 can be adjusted more flexibly as needed to achieve corresponding adjustments to the position of the sliding groove 12831. This flexibility allows the linkage mechanism 128 to better adapt to fuselage 110 structures of different sizes and shapes, as well as different installation space requirements. Furthermore, when the sliding groove 12831 experiences significant wear, the second connecting rod 1283 can be directly replaced without modifying the fuselage 110 installation structure. Therefore, this facilitates the later replacement and maintenance of the linkage mechanism 128.

[0112] Under the condition of meeting the lifting operation requirements of the cleaning mechanism 130, this utility model does not limit the sliding direction of the sliding member 1282 relative to the body 110. However, optionally, please refer to Figure 4 and Figure 14 In one embodiment of this utility model, the sliding direction of the sliding member 1282 relative to the body 110 (i.e., the extending direction of the slide groove 12831) is parallel to the traveling direction of the cleaning device 100. The traveling direction of the cleaning device 100 is as follows: Figure 4 As shown in the N-axis direction, the sliding direction of the slider 1282 is horizontal.

[0113] In this embodiment, the sliding direction of the slider 1282 relative to the body 110 is set to be parallel to the traveling direction of the cleaning equipment 100. This setting makes the positioning and installation of the slide 12831 and the body 110 more convenient and intuitive, which helps to reduce motion errors caused by assembly deviations. On the other hand, it also simplifies the calculation of the lifting stroke and sliding stroke, which not only reduces the computational complexity but also improves the control accuracy of the linkage mechanism 128's running trajectory.

[0114] Please see Figures 12 to 17 In one embodiment of this utility model, the rotational speed of the first output gear 1241 is greater than that of the second output gear 1251. During the operation of the drive unit 121, the first output gear 1241 gradually leads the second output gear 1251 in angular position, thereby creating a phase difference between the first output gear 1241 and the second output gear 1251. Please refer to [link / reference]. Figure 14 and Figure 22 The first connecting rod 1281 includes a rod body 12811 and a connecting part 12812. One end of the rod body 12811 is rotatably connected to the slider 1282, and the other end of the rod body 12811 is slidably connected to the connecting part 12812 via a sliding assembly 1284. The connecting part 12812 is fixedly connected to the first output gear 1241. It should be noted that in this embodiment, the fixed connection method between the connecting part 1281 and the first output gear 1241 can refer to the fixed connection method between the first connecting rod 1281 and the first output gear 1241 in the above embodiments, and the structural description of the slider 1282 can also refer to the structural description of the slider 1282 in the above embodiments, and will not be repeated here.

[0115] Specifically, in this embodiment, the slider 1282 is a bearing, and the first output gear 1241 is a gear shaft structure. The first output gear 1241 is rotatably connected to the bracket 132 via the bearing. Please refer to [link to previous text]. Figure 16 and Figure 22 The connecting part 12812 includes a flange end 12813 and a plug-in end 12814. A first plug-in hole 12411 is provided at one end of the first output gear 12411 facing the connecting part 12812. The plug-in end 12814 is fixedly engaged within the first plug-in hole 12411 to achieve a fixed connection between the connecting part 12812 and the first output gear 1241. The rod part 12811 is rotatably connected to the plug-in end 12814, and along the axial direction of the first output gear 1241, the rod part 12811 is located between the flange end 12813 and the first output gear 1241.

[0116] During the rotation of the first output gear 1241, the connecting part 12812 rotates with the first output gear 1241 to a preset angle, and then drives the rod part 12811 to rotate synchronously through the sliding assembly 1284. The sliding assembly 1284 can have various structures. For example, the sliding assembly 1284 can include a first sliding member and a second sliding member that cooperate with each other, with the first sliding member sliding along the second sliding member. The first sliding member and the second sliding member can be a slider and groove structure, or a guide rail and slider structure, etc.

[0117] Specifically, the first sliding member and the second sliding member are respectively disposed at the ends of the connecting portion 12812 and the rod portion 12811. In the initial stage of the rotation of the first output gear 1241, the first output gear 1241 drives the connecting portion 12812 to rotate synchronously, and the first sliding member slides along the second sliding member. At this time, the rod portion 12811 remains stationary relative to the connecting portion 12812. When the connecting portion 12812 rotates to a preset angle with the first output gear 1241, the first sliding member and the second sliding member form a stop engagement, and sliding between them stops. As the first output gear 1241 continues to rotate, the first sliding member and the second sliding member will rotate synchronously as a whole, thereby driving the rod portion 12811 to rotate synchronously with the first output gear 1241.

[0118] Since the rotational speed of the first output gear 1241 is greater than that of the second output gear 1251, a phase difference will inevitably occur between them during rotation. If left uncontrolled, this phase difference will cause the lifting and lowering operation of the cleaning mechanism 130 and the rotation of the shielding member 140 to be out of sync, thus affecting the normal operation of the cleaning equipment 100. In this embodiment, by providing a sliding component 1284 between the rod portion 12811 and the connecting portion 12812, when the first output gear 1241 rotates, the connecting portion 12812 will first rotate with the first output gear 1241 to a preset angle, and then drive the rod portion 12811 to rotate synchronously via the sliding component 1284. This design allows the connecting portion 12812 to rotate independently in the initial stage of the first output gear 1241's rotation, while the rod portion 12811 remains stationary, thus providing a buffer space for the phase difference. After the connecting portion 12812 rotates to the preset angle, it will again drive the rod portion 12811 to rotate synchronously via the sliding component 1284. In this way, during the final stage of the lifting operation, the lifting action of the cleaning mechanism 130 and the rotation action of the shielding component 140 can be synchronized, thereby ensuring the normal cleaning operation of the cleaning equipment 100.

[0119] Please see Figures 14 to 16In one embodiment of this utility model, the sliding component 1284 includes an arc-shaped groove 12841 and a protrusion 12842. The arc-shaped groove 12841 is disposed on the rod portion 12811, and the protrusion 12842 is disposed on the connecting portion 12812. The protrusion 12842 slides along the arc-shaped groove 12841, and the rotation axis of the arc-shaped groove 12841 coincides with the rotation axis of the first output gear 1241. In another embodiment, the arc-shaped groove 12841 may be disposed on the connecting portion 12812, and the protrusion 12842 may be disposed on the rod portion 12811. The protrusion 12842 slides along the arc-shaped groove 12841, and the rotation axis of the arc-shaped groove 12841 coincides with the rotation axis of the first output gear 1241.

[0120] In this embodiment, by configuring the sliding component 1284 as an arc-shaped groove 12841 and a protrusion 12842, on the one hand, the protrusion 12842 slides along the arc-shaped groove 12841, forming a stable guiding structure. This ensures that the relative motion trajectory between the rod body 12811 and the connecting part 12812 is precisely controllable, thereby reducing the probability of deviation or wobbling between them during movement. On the other hand, since the rotation axis of the arc-shaped groove 12841 coincides with the rotation axis of the first output gear 1241, the motion trajectory of the sliding component 1284 is consistent with the rotational motion of the first output gear 1241, thereby further improving the stability and accuracy of operation.

[0121] Considering the smoothness of the lifting and lowering operation of the cleaning mechanism 130 relative to the body 110, optionally, please refer to Figures 20 to 21 In one embodiment of this utility model, two sets of linkage mechanisms 128 are provided, and the two sets of linkage mechanisms 128 are respectively arranged on both sides of the outer side of the cleaning mechanism 130 along its length. One set of linkage mechanisms 128 and the transmission mechanism 122 are located on the same side of the cleaning mechanism 130 along its length. The two sets of linkage mechanisms 128 can be symmetrically arranged on both sides of the cleaning mechanism 130 or asymmetrically arranged. In this embodiment, the two sets of linkage mechanisms 128 are symmetrically arranged on both sides of the cleaning mechanism 130 along its length. The two sets of linkage mechanisms 128 are connected by a synchronization mechanism 150. When the first output gear 1241 rotates, the synchronization mechanism 150 can realize the synchronous operation of the two sets of linkage mechanisms 128.

[0122] There are various specific structural arrangements for connecting the two sets of linkage mechanisms 128 via the synchronization mechanism 150. For example, in one embodiment, a synchronization shaft can be provided between the two sets of linkage mechanisms 128. The two ends of the synchronization shaft are fixedly connected to the input ends of the linkage mechanisms 128 on both sides. The synchronization shaft is supported on the bracket 132 of the cleaning mechanism 130 by bearings, and one end of the synchronization shaft is fixedly connected to the first output gear 1241. When the first output gear 1241 rotates, the synchronization shaft synchronously transmits the rotation of the first output gear 1241 to the linkage mechanism 128 on the side away from the first output gear 1241, thereby achieving synchronous operation of the two linkage mechanisms 128.

[0123] In another embodiment, a synchronous pulley assembly can be provided on the two linkage mechanisms 128. The driving pulley in the synchronous pulley assembly is fixedly connected to the first output gear 1241, and the driven pulley in the synchronous pulley assembly is connected to the input end of the linkage mechanism 128 on the side away from the first output gear 1241. When the first output gear 1241 rotates, the synchronous pulley assembly synchronously transmits the rotation of the first output gear 1241 to the linkage mechanism 128 on the side away from the first output gear 1241, thereby realizing the synchronous operation of the two linkage mechanisms 128.

[0124] In this embodiment, by arranging two sets of linkage mechanisms 128 on the outer sides of the cleaning mechanism 130 along its length, a dual-sided synchronous drive structure can be formed. This structure allows the lifting and lowering motion of the cleaning mechanism 130 to be completed jointly by the linkage mechanisms 128 on both sides, thereby achieving a uniform distribution of force during the lifting and lowering process. Compared with a single-sided drive scheme, the dual-sided synchronous drive structure can effectively avoid the risk of uneven load and prevent problems such as swaying or movement jamming caused by uneven force, thereby improving the smoothness and accuracy of the lifting and lowering operation of the cleaning mechanism 130. In addition, since the dual-sided synchronous drive structure can form a dual-sided support structure on both sides of the cleaning mechanism 130 along its length, it can enhance the overall rigidity and load-bearing capacity of the cleaning mechanism 130. This not only helps to enhance the cleaning mechanism 130's ability to withstand the loads and impacts generated during cleaning operations, but also effectively extends the service life of the cleaning equipment 100.

[0125] Please see Figures 21 to 23In one embodiment of this utility model, the synchronization mechanism 150 includes a drive shaft 151 and a support base 152. The support base 152 is rotatably connected to the end of the cleaning mechanism 130 away from the first output gear 1241. Specifically, the support base 152 is rotatably connected to the end of the bracket 132 away from the first output gear 1241. The rotatable connection method includes, but is not limited to, rotatably connecting the bracket 132 via a slewing bearing. The drive shaft 151 extends along the length direction of the cleaning mechanism 130, one end of the drive shaft 151 is fixedly connected to the first output gear 1241, and the other end of the drive shaft 151 is fixedly connected to the support base 152. The fixed connection method between the drive shaft 151, the first output gear 1241, and the support base 152 is not limited; it can be a snap-fit ​​connection or a bolt connection, etc.

[0126] Specifically, please refer to Figure 22 In this embodiment, the drive shaft 151 has a locking portion 1511 at both ends, the first output gear 1241 has a first locking hole 12412 at the end facing away from the connecting portion 12812, and the support base 152 has a second locking hole 1521 at the end facing the drive shaft 151. One locking portion 1511 is locked into the first locking hole 12412 to achieve a fixed connection between the drive shaft 151 and the first output gear 1241. The other locking portion 1511 is locked into the second locking hole 1521 to achieve a fixed connection between the drive shaft 151 and the support base 152.

[0127] One set of the two linkage mechanisms 128 is fixedly connected to the first output gear 1241, and the other set is fixedly connected to the support base 152. The method of fixing the linkage mechanism 128 closer to the first output gear 1241 to the first output gear 1241 can be referred to the relevant description in the above embodiments, and will not be repeated here. The method of fixing the linkage mechanism 128 farther from the first output gear 1241 to the support base 152 can be varied, such as snap-fit ​​fixing or bolt fixing. For details, please refer to... Figure 23 In this embodiment, on the side of the drive shaft 151 away from the first output gear 1241, the support base 152 is provided with a second insertion hole 1522 at the end opposite to the drive shaft 151. The insertion end 12814 of the connecting part 12812 is fixedly engaged in the second insertion hole 1522 to realize the fixed connection between the connecting part 12812 and the support base 152, that is, to realize the connection between the connecting rod mechanism 128 on this side and the support base 152.

[0128] In this embodiment, by setting up a transmission shaft 151 and a support base 152, when the first output gear 1241 rotates, part of its power is transmitted to the corresponding linkage mechanism 128, driving the linkage mechanism 128 to move. Another part of the power can be transmitted through the transmission shaft 151 to the support base 152, which then drives the corresponding linkage mechanism 128 to operate, thereby achieving synchronous operation of the linkage mechanisms 128 on both sides. Since both ends of the transmission shaft 151 are fixedly connected to the support base 152 and the first output gear 1241 respectively, a rigid connection structure can be formed. This structure ensures that the power of the first output gear 1241 can be directly transmitted to the support base 152 through the transmission shaft 151, thereby driving the two sets of linkage mechanisms 128 to move synchronously. This avoids the elastic deformation or slippage that may occur with flexible connections (such as belts or chains), which is beneficial for ensuring the accuracy of synchronous transmission.

[0129] Please see Figure 26 In one embodiment of this utility model, the cleaning mechanism 130 further includes a support assembly 133. The bracket 132 has a receiving cavity 1321 with an opening 1322 facing the surface to be cleaned 190. The support assembly 133 is rotatably mounted within the receiving cavity 1321. The cleaning component 131 is a mop, which is wound around the outer periphery of the support assembly 133. The support assembly 133 can take various forms, such as a roller structure or a tracked structure. A shielding component 140 is rotatably mounted on the bracket 132 and disposed on the outer periphery of the receiving cavity 1321.

[0130] Please see Figure 7 When the shielding member 140 is in the first rotating position, it closes the opening 1322, sealing the cleaning member 131 within the receiving cavity 1321. This isolates the cleaning member 131 from the surface 190 to be cleaned when the cleaning mechanism 130 is in the raised position, preventing dust or stains on the cleaning member 131 from falling onto the surface 190. (See also...) Figure 5 When the shielding member 140 is in the second rotation position, the shielding member 140 opens the opening 1322, exposing the cleaning member 131 to the opening 1322. In this way, when the cleaning mechanism 130 is in the lowered position, the cleaning member 131 can contact the surface to be cleaned 190 and perform routine cleaning operations.

[0131] In this embodiment, when the shielding member 140 is in the first rotation position, the shielding member 140 closes the opening 1322, thus sealing the cleaning member 131 within the receiving cavity 1321. This improves the isolation effect of the shielding member 140 between the cleaning member 131 and the surface to be cleaned 190, further reducing the probability of dust, stains, or water droplets on the cleaning member 131 dripping onto the surface to be cleaned 190, thereby effectively reducing the pollution caused by the cleaning member 131 to carpets, etc. When the shielding member 140 is in the second rotation position, the shielding member 140 opens the opening 1322, allowing the cleaning member 131 to be fully exposed and in contact with the surface to be cleaned 190. This design ensures that the shielding member 140 does not interfere with the normal operation of the cleaning member 131, thereby effectively guaranteeing cleaning efficiency and cleaning quality.

[0132] Specifically, please refer to Figure 9 , Figure 26 and Figure 28 In this embodiment, the support assembly 133 adopts a roller structure. The blocking member 140 includes an arc-shaped plate 141 and connecting plates 142 disposed at both ends of the arc-shaped plate 141. The rotation axis of the arc-shaped plate 141 is coaxially arranged with the rotation axis of the support assembly 133. The connecting plates 142 at both ends are rotatably connected to both ends of the support assembly 133. One of the connecting plates 142 is fixedly connected to the second output gear 1251. The fixed connection can be integrally injection molded or fixed with bolts. In this embodiment, in order to facilitate the installation between the second output gear 1251 and the blocking member 140, the second output gear 1251 and the blocking member 140 are integrally injection molded.

[0133] Please see Figure 7 and Figure 8 In one embodiment of this utility model, a scraper 160 is provided on the bracket 132 near the opening 1322. The scraper 160 is located on the rear side of the cleaning device 100 in the forward direction and can abut against the surface 190 to be cleaned when the cleaning device 130 is in the lowered position. It should be noted that the scraper 160 in this embodiment is made of flexible materials such as rubber and silicone. The scraper 160 can effectively scrape away water stains, dirt, etc. left on the surface 190 to be cleaned after cleaning during the cleaning operation of the cleaning device 131, thereby further improving the cleaning effect. When the blocking member 140 closes the opening 1322, the blocking member 140 abuts against the scraper 160 and causes the scraper 160 to bend towards the rear side in the forward direction of the cleaning device 100.

[0134] In this embodiment, since the shielding member 140 can bend the squeegee 160 towards the rearward side in the forward direction of the cleaning device 100, the squeegee 160 can be further away from the surface to be cleaned 190 in the height direction. This reduces the possibility of the squeegee 160 coming into contact with the carpet, thus reducing the risk of the squeegee 160 contaminating the carpet. Simultaneously, this arrangement also prevents a gap from forming between the shielding member 140 and the squeegee 160 when the opening 1322 is closed. This further reduces the probability of stains or water on the cleaning member 131 dripping onto the carpet through the gap, thereby further reducing the probability of contaminating the carpet.

[0135] Please see Figure 7 , Figure 27 and Figure 29 In one embodiment of this utility model, the cleaning device 100 further includes a first detection component 170 and a second detection component 180. The first detection component 170 is used to detect whether the cleaning mechanism 130 is in a raised position and whether the blocking member 140 is in a first rotation position. The second detection component 180 is used to detect whether the cleaning mechanism 130 is in a lowered position and whether the blocking member 140 is in a second rotation position. The first detection component 170 and the second detection component 180 can have various structural types. For example, the first detection component 170 and the second detection component 180 can be a combination structure of Hall sensor and magnet, a combination structure of mechanical switch and stop, a combination structure of photoelectric switch and baffle, etc.

[0136] It should be noted that in this invention, the lifting and lowering movement of the cleaning mechanism 130 and the rotational movement of the blocking member 140 are always synchronized at the final position. Specifically, when the cleaning mechanism 130 is in the raised position, the blocking member 140 rotates synchronously to the first position; when the cleaning mechanism 130 is in the lowered position, the blocking member 140 rotates synchronously to the second position. This ensures the coordination of the positions of the cleaning mechanism 130 and the blocking member 140 at the end of the operation.

[0137] In this embodiment, the first detection component 170 may be disposed on the bracket 132 of the body 110 and the cleaning mechanism 130, and is used to detect whether the cleaning mechanism 130 is in the raised position. Alternatively, the first detection component 170 may be disposed on the shield 140 and the bracket 132, and is used to detect whether the shield 140 is in the first rotation position. The second detection component 180 may be disposed on the body 110 and the bracket 132, and is used to detect whether the cleaning mechanism 130 is in the lowered position. Alternatively, the second detection component 180 may be disposed on the shield 140 and the bracket 132, and is used to detect whether the shield 140 is in the second rotation position.

[0138] Specifically, in this embodiment, please refer to Figure 29The first detection component 170 includes a first detection switch 171 and a first stop 172. The first detection switch 171 is mounted on the body 110, and the first stop 172 is mounted on the bracket 132, with their positions corresponding to each other. When the cleaning mechanism 130 rises to the raised position, the first stop 172 triggers the first detection switch 171, generating a first positioning detection signal. At this time, the controller of the cleaning equipment 100 (or the controller built into the drive component 121) receives the first positioning detection signal and controls the drive component 121 to stop running, thereby synchronously stopping the lifting movement of the cleaning mechanism 130 and the rotation movement of the shield 140.

[0139] Please see Figure 27 The second detection component 180 includes a second detection switch 181 and a second stop 182. The second detection switch 181 is mounted on the bracket 132, and the second stop 182 is mounted on the connecting plate 142 and positioned close to the second detection switch 181. The second stop 182 can be integrally formed with the connecting plate 142 or fixedly connected by bolts. In this embodiment, the second stop 182 is integrally formed with the connecting plate 142. When the blocking member 140 rotates to the second rotation position, the second stop 182 triggers the second detection switch 181, generating a second positioning detection signal. At this time, the controller (or the controller built into the drive member 121) receives the second positioning detection signal and controls the drive member 121 to stop running, thereby synchronously stopping the lifting movement of the cleaning mechanism 130 and the rotation of the blocking member 140.

[0140] In this embodiment, by integrating the detection of the lifting position of the cleaning mechanism 130 and the rotation position of the blocking member 140 into the same detection component, separate detection components for the lifting operation of the cleaning mechanism 130 and the rotation operation of the blocking member 140 are avoided. This integrated design not only effectively reduces the total number of detection components and simplifies the overall number of parts, but also helps to reduce manufacturing costs. At the same time, the integrated detection component can simultaneously acquire the position status of the cleaning mechanism 130 and the blocking member 140, reducing the number of signal acquisition and processing steps, thereby improving detection efficiency and the response speed of the control system, which is conducive to achieving more precise motion control.

[0141] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.

The scraper is located on the rear side of the cleaning device in the forward direction and can abut against the surface to be cleaned when the cleaning mechanism is in the lowered position. When the shield closes the opening, the shield abuts against the scraper and causes the scraper to bend toward the rear side in the direction of travel of the cleaning equipment.

14. The cleaning equipment according to claim 1, characterized in that, The cleaning mechanism has at least a raised position and a lowered position during the lifting and lowering movement. In the raised position, the cleaning component is lifted away from the surface to be cleaned; in the lowered position, the cleaning component contacts the surface to be cleaned; when the cleaning mechanism is in the raised position, the blocking component rotates to the first rotation position; when the cleaning mechanism is in the lowered position, the blocking component rotates to the second rotation position.

15. The cleaning equipment according to claim 14, characterized in that, The cleaning equipment further includes a first detection component and a second detection component. The first detection component is used to detect whether the cleaning mechanism is in a raised position and whether the shielding member is in a first rotation position. The second detection component is used to detect whether the cleaning mechanism is in a lowered position and whether the shielding member is in a second rotation position.
