[0044] Below, refer to Figures 1 to 7 Some embodiments of this application will be described in detail.

[0045] The first aspect of this application provides a cleaning device 100. For example... Figure 1 and Figure 2As shown, the cleaning device 100 includes a cleaning base 1, a handle assembly 2, and a support assembly 3.

[0046] The cleaning equipment 100 is a device used to clean the work surface 10 to be cleaned. The cleaning equipment 100 includes, but is not limited to, vacuum cleaners, floor scrubbers, mops, and sweeper-mop combos. The work surface 10 to be cleaned includes, but is not limited to, floors, tabletops, or the surfaces of other objects and components.

[0047] The cleaning base 1 is movable on the working surface 10 and is a structural component used to clean the working surface 10 to be cleaned.

[0048] The working surface 10 refers to the surface that contacts the cleaning base 1. For example, when the cleaning equipment 100 is operating on the ground, the ground can be regarded as the working surface 10. It should be noted that the working surface 10 can be a horizontal surface or a surface that is inclined relative to the horizontal surface (e.g., a slope).

[0049] The direction of movement of the cleaning base 1 on the working surface 10 can also be referred to as the travel direction X. The travel direction X refers to the direction of movement of the cleaning equipment 100 along the working surface 10 during the cleaning operation, and can also be understood as the direction from the rear end of the cleaning equipment 100 to the front end. During the cleaning operation, the front end of the cleaning equipment 100 passes the working surface 10 before the rear end.

[0050] The cleaning base 1 includes a cleaning roller brush 11. The cleaning roller brush 11 can contact the working surface 10 and can rotate at high speed to clean the working surface 10. The number of cleaning roller brushes 11 can be one or more (two or more). This application embodiment does not specifically limit the number of cleaning roller brushes 11.

[0051] In some embodiments, the cleaning base 1 may further include freely rotatable rollers 12. The rollers 12 can assist the cleaning base 1 in moving on the working surface 10. The rollers 12 may be disposed on opposite sides of the cleaning base 1 along its width direction. During cleaning operations, if the cleaning base 1 collides with objects such as furniture or walls, the rotation of the rollers 12 can reduce the impact force, providing a certain buffering effect, thereby reducing the possibility of damage to the cleaning base 1 or the collided object.

[0052] The handle assembly 2 refers to the structural component for the user to grip. The user grips the handle assembly 2 to operate the cleaning base 1 to perform cleaning operations on the work surface 10.

[0053] In this embodiment, the handle assembly 2 is rotatably connected to the cleaning base 1, thereby facilitating the user to adjust the cleaning angle of the cleaning device 100 and flexibly change the cleaning posture of the cleaning device 100. For example, when cleaning the work surface 10 in some low-ceilinged spaces, the user can tilt the handle assembly 2 so that the cleaning base 1 can extend into the low-ceilinged space as much as possible, thereby achieving a better cleaning effect.

[0054] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, the handle assembly 2 includes a handle base 21, a handle support 22, and a handle 23.

[0055] The handle base 21 is rotatably connected to the cleaning base 1, allowing for flexible adjustment of the angle of the handle assembly 2 relative to the cleaning base 1, which helps the cleaning device 100 better adapt to various cleaning scenarios. In some embodiments, the handle base 21 can be rotatably connected to the cleaning base 1 about the lateral direction. The lateral direction can be the horizontal direction or the left-right direction of the cleaning device 100. The lateral direction is perpendicular to the travel direction X. In some embodiments, the handle base 21 can also be rotatably connected to the cleaning base 1 about the vertical direction. The vertical direction can be the height direction of the cleaning device 100. The vertical direction is perpendicular to both the travel direction X and the lateral direction. In some embodiments, the handle base 21 can also be rotatably connected to the cleaning base 1 about the extension direction of the handle assembly 2.

[0056] For example, the handle base 21 can be rotatably connected to the cleaning base 1 via a hinge assembly.

[0057] As another example, the handle base 21 can be rotatably connected to the cleaning base 1 via a universal bearing.

[0058] This application does not impose specific limitations on the connection method between the handle base 21 and the cleaning base 1. Any suitable method can be used to connect the two, as long as the handle assembly 2 can rotate relative to the cleaning base 1.

[0059] The handle support 22 is connected to the handle base 21 and is located between the handle base 21 and the handle 23. The handle support 22 provides a certain support function; for example, structures such as fans and water tanks can be installed on the handle support 22.

[0060] In this embodiment, the wastewater tank 221 is disposed on the handle support 22. In some other embodiments, the clean water tank is disposed on the handle support 22, or both the clean water tank and the wastewater tank 221 are disposed on the handle support 22. In some embodiments, devices such as motors and power supplies may also be disposed on the handle support 22.

[0061] Along the axial direction of the handle assembly 2, the handle 23 is connected to the side of the handle support 22 facing away from the handle base 21. The handle 23 may include a grip portion 231 and a connecting rod 232, with the connecting rod 232 connecting the grip portion 231 and the handle support 22. In some embodiments, the connecting rod 232 may be a telescopic rod, thereby facilitating the user to adjust the grip height according to actual conditions.

[0062] When using the cleaning device 100, users sometimes adjust the cleaning posture of the cleaning device 100 by tilting the handle assembly 2. When the handle assembly 2 is tilted to a certain degree, a large supporting force is required to support it and keep the handle assembly 2 in the tilted state. The weight of the various modules on the handle assembly 2 is transferred to the handle 23, which puts a great burden on the user.

[0063] In this embodiment, the cleaning device 100 includes a support component 3, which is movably connected to the handle assembly 2. The support component 3 is capable of supporting the working surface 10 when the handle assembly 2 is tilted away from the cleaning base 1. Specifically, the support component 3 is capable of supporting the working surface 10 when the handle assembly 2 is tilted away from the cleaning base 1 along the travel direction X. Therefore, the cleaning device 100 provided in this application can provide a certain degree of support to the handle assembly 2 through the support component 3, thereby reducing the support force borne by the user and alleviating the burden on the user when using the cleaning device 100.

[0064] The movable connection between the support component 3 and the handle component 2 includes, but is not limited to, a rotational connection and a sliding connection. In some embodiments, the support component 3 is rotatably connected to the handle component 2. In some embodiments, the support component 3 can also be movably connected to the handle component 2 in any other suitable manner, such as a sliding connection, a sliding connection, a rotational connection, etc. Those skilled in the art should understand that any connection method in which the support component 3 can support the working surface 10 when the handle component 2 is tilted away from the cleaning base 1 is within the scope of protection of this application.

[0065] Therefore, when the handle assembly 2 is tilted away from the cleaning base 1, the support assembly 3 can support it on the working surface 10. Even when the handle assembly 2 is tilted at a large angle, the support assembly 3 can maintain contact with the working surface 10, thereby providing good support for the handle assembly 2. This ensures that the handle assembly 2 is well supported regardless of its position, providing a better user experience.

[0066] Moreover, even if the user needs to temporarily pause the cleaning operation during use, the handle component 2 can maintain its current tilted state with the support of the support component 3, without having to frequently adjust it to the initial state, making it easy for the user to resume the cleaning operation at any time and making it more convenient to use.

[0067] When the handle assembly 2 of the cleaning device 100 is in an upright position or tilted towards the cleaning base 1, the weight of the handle assembly 2 will not act on the handle 23. At this time, the support assembly 3 may or may not be supported on the working surface 10. Those skilled in the art will understand that as long as the handle assembly 2 is tilted away from the cleaning base 1, the support assembly 3 can support the working surface 10, regardless of whether the handle assembly 2 of the cleaning device 100 is in an upright position or tilted towards the cleaning base 1, and regardless of whether the support assembly 3 is supported on the working surface 10, all are within the scope of protection of this application.

[0068] Here, the movement of the support component 3 relative to the handle component 2 can be achieved by an automated drive device, or by a user manually adjusting the support component 3 relative to the handle component 2.

[0069] As described above, in some embodiments of this application, the support component 3 is rotatably connected to the handle component 2. It should be noted that the rotatable connection between the support component 3 and the handle component 2 can also be a rotatable connection with the handle support member 22. The support component 3 includes a support body 31 and a support wheel 32. The support body 31 is the load-bearing component of the support component 3. The end of the support body 31 away from the working surface 10 is rotatably connected to the handle component 2. The support wheel 32 is rotatably connected to the end of the support body 31 facing the working surface 10. The rotatable connection between the support body 31 and the handle component 2 can also be a rotatable connection between the support body 31 and the handle support member 22. Therefore, the friction between the support component 3 and the working surface 10 can be reduced by the support wheel 32, thereby making the movement of the cleaning device 100 smoother during the cleaning process and further improving the user experience.

[0070] Those skilled in the art will understand that in some other embodiments, the support component 3 may not have the support wheel 32, as long as it does not affect the movement of the cleaning equipment 100 on the working surface 10. For example, a smooth surface can be provided at the contact position between the support component 3 and the working surface 10 to reduce friction between the support component 3 and the working surface 10.

[0071] In some embodiments of this application, the support body 31 is rotatably connected to the handle assembly 2 about a first direction Y. The first direction Y intersects the extending direction of the handle assembly 2, allowing the support wheel 32 to move away from or towards the cleaning base 1 along the travel direction of the cleaning base 1.

[0072] In this embodiment, the first direction Y can also be referred to as the width direction of the cleaning device 100. In some embodiments, the first direction Y is substantially perpendicular to the extension direction of the handle assembly 2. When the support body 31 is rotatably connected to the handle assembly 2 about the first direction, the support assembly 3 can be opened or closed relative to the handle assembly 2. When the support assembly 3 is open relative to the handle assembly 2, the support assembly 3 rotates relative to the handle assembly 2 away from the handle assembly 2 and the cleaning base 1, so that the support wheel 32 moves away from the handle assembly 2 and the cleaning base 1. When the support assembly 3 is closed relative to the handle assembly 2, the support assembly 3 rotates relative to the handle assembly 2 towards the handle assembly 2 and the cleaning base 1, so that the support wheel 32 moves towards the handle assembly 2 and the cleaning base 1.

[0073] In some embodiments of this application, such as Figure 3 , Figure 4 and Figure 7 As shown, the support assembly 3 includes a first rotating shaft 71. The axis of the first rotating shaft 71 is in the first direction Y, and the support body 31 is rotatably connected to the handle assembly 2 via the first rotating shaft 71. Therefore, the support assembly 3 can rotate relative to the handle assembly 2 about the first direction Y via the first rotating shaft 71, allowing the support assembly 3 to support the working surface 10 when the handle assembly 2 is tilted away from the cleaning base 1 along the travel direction X, reducing the burden on the user and improving the user experience.

[0074] The handle assembly 2 may be provided with a first support base 24. There may be two first support bases 24. The two first support bases 24 are arranged at a distance along a first direction Y. Each first support base 24 has a through hole. Both ends of the first rotating shaft 71 pass through the through holes of the two first support bases 24, thereby being fixedly supported by the first support bases 24.

[0075] Of course, those skilled in the art should understand that in some other embodiments, the number of first support seats 24 may be one. Instead, two support seats are provided on the support assembly 3 and arranged at intervals along the first direction Y. The two support seats on the support assembly 3 are provided with through holes. The two ends of the first rotating shaft 71 pass through the through holes of the two support seats of the support assembly, thereby being fixedly supported by the first support seats 24. This application does not specifically limit the connection position of the first rotating shaft 71; any scheme that enables the rotation of the support assembly 3 relative to the handle assembly 2 is within the protection scope of this application.

[0076] In some embodiments of this application, the support body 31 can also be rotatably connected to the handle assembly 2 about a second direction, which is perpendicular to the first direction Y.

[0077] Since the support body 31 can rotate around the first direction Y, the second direction will also change during the rotation of the support body 31 around the first direction Y. Those skilled in the art should understand that any direction perpendicular to the first direction Y can be referred to as the second direction. When the extension direction of the support component 3 is parallel to the extension direction of the handle component 2, that is, when the support component 3 is closed relative to the handle component 2, the second direction is approximately perpendicular to both the first direction Y and the extension direction of the handle component 2. In some embodiments, the handle component 2 can rotate relative to the cleaning base 1 around the extension direction of the handle component 2, or swing left and right around a direction perpendicular to the extension direction of the handle component 2. In this case, setting the support component 3 to rotate around the handle component 2 in the second direction allows the support component 3 to be stably supported on the working surface 10. When the support body 31 is rotated around the handle component 2 in the second direction, the support component 3 can rotate relative to the handle component 2 to the left or right. That is, the handle component 2 can shift or twist relative to the support component 3 to the left or right, thereby further improving the operational flexibility of the handle component 2. Here, left and right refer to the left and right sides relative to the travel direction X of the cleaning device 100.

[0078] In some embodiments of this application, such as Figure 7 As shown, the support assembly 3 also includes a second pivot 72 and a connector 73. The second pivot 72 extends along a second direction, and the axial direction of the second pivot 72 is the second direction. One end of the connector 73 is rotatably connected to one of the handle assembly 2 and the support body 31 via a first pivot 71. The other end of the connector 73 is rotatably connected to the other of the handle assembly 2 and the support body 31 via the second pivot 72.

[0079] For example, a first pivot 71 is connected to a handle assembly 2. A second pivot 72 is connected to a support body 31. One end of a connector 73 is fitted onto the first pivot 71 and rotatably connected to the handle assembly 2. The other end of the connector 73 is fitted onto the second pivot 72 in a manner that allows it to rotate around the second pivot 72 and rotatably connected to the support body 31.

[0080] As another example, a first pivot 71 is connected to a support body 31. A second pivot 72 is connected to a handle assembly 2. One end of a connector 73 is rotatably connected to the support body 31 via the first pivot 71. The other end is rotatably connected to the handle assembly 2 via the second pivot 72.

[0081] Therefore, the handle assembly 2 can also be rotated around a second direction perpendicular to the first direction Y via the second rotating shaft 72. That is, the handle assembly 2 can be rotated left and right along the width direction of the cleaning device 100, which further improves the operational flexibility of the handle assembly 2 and makes it easier for users to perform cleaning operations.

[0082] For example, such as Figure 3 and Figure 7 As shown, a second support base 34 may be provided on the support assembly 3. There may be two second support bases 34, which are arranged at intervals along a second direction. Each second support base 34 has a through hole. The two ends of the second rotating shaft 72 pass through the through holes of the two second support bases 34, thereby being fixedly supported by the second support bases 34.

[0083] Both ends of the connector 73 are provided with connecting through holes, and one connecting through hole of the connector 73 is rotatably fitted onto the first rotating shaft 71, and the other connecting through hole is rotatably fitted onto the second rotating shaft 72, thereby realizing the rotation of the handle assembly 2 in two degrees of freedom, which is more flexible.

[0084] Those skilled in the art will understand that any method that enables multi-degree-of-freedom rotation of the handle assembly 2 is within the scope of protection of this application. In some other embodiments, the support assembly 3 may also be connected to the handle assembly 2 via a universal bearing, thereby enabling the support assembly 3 to rotate relative to the handle assembly 2 with multiple degrees of freedom.

[0085] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, the handle assembly 2 includes a first end 2a and a second end 2b along its axial direction. The first end 2a is rotatably connected to the cleaning base 1. The second end 2b is the end away from the cleaning base 1. The distance from the first end 2a of the handle assembly 2 to the position where the support body 31 is rotatably connected to the handle assembly 2 (connection point P) is greater than 1 / 3 of the longitudinal length of the handle assembly 2, and the distance from the second end 2b of the handle assembly 2 to the position where the support body 31 is rotatably connected to the handle assembly 2 (connection point P) is greater than 1 / 3 of the longitudinal length of the handle assembly 2.

[0086] The first end 2a and the second end 2b of the handle assembly 2 are the two ends of the handle assembly 2 that are furthest apart along its axial direction. The distance between the first end 2a and the second end 2b is the maximum length of the handle assembly 2 along its axial direction, that is, the longitudinal length of the handle assembly 2. Along the axial direction of the handle assembly 2, the first end 2a is located below the second end 2b. That is, the first end 2a is the end of the handle assembly 2 closest to the working surface 10. The second end 2b is the end of the handle assembly 2 furthest from the working surface 10. Specifically, the first end 2a is located on the handle base 21 of the handle assembly 2. The second end 2b is located on the handle 23 of the handle assembly 2.

[0087] The distance between the position (connection point P) where the support body 31 and the handle assembly 2 are rotatably connected and the first end 2a of the handle assembly 2 is greater than 1 / 3 of the longitudinal length of the handle assembly 2. This allows the connection point P to be located away from the cleaning base 1. This arrangement results in a greater torque (relative to the torque on the cleaning base 1) exerted by the supporting force of the working surface 10 on the support assembly 3 when the handle assembly 2 is tilted, thereby further reducing the force required by the user's hand.

[0088] Therefore, the support component 3 is rotatably connected to the handle component 2 in the middle region of the handle component 2. Specifically, it is located slightly below the middle region (i.e., closer to the working surface 10). As a result, the support component 3 does not need to be made too long in the axial direction of the handle component 2, which helps to save materials and reduce production costs.

[0089] Furthermore, the connection point P between the support component 3 and the handle support 22 is closer to the working surface 10, which makes the overall structure after the support component 3 and the handle support 22 are connected have a lower center of gravity, thus improving stability.

[0090] Furthermore, when the support assembly 3 is rotated by the drive assembly 4, the connection point P is located on the lower middle side, which helps reduce the energy consumption of the drive assembly 4, thereby contributing to energy conservation and emission reduction, and also improving response speed. As long as the position of the rotational connection between the support body 31 and the handle assembly 2 satisfies the above relationship, and the connection point P is located in a suitable position, these rotational connection positions are all within the protection scope of this application.

[0091] In some embodiments of this application, such as Figures 3 to 5 As shown, the cleaning device 100 also includes a drive assembly 4. The drive assembly 4 is connected to the support assembly 3, and drives the support assembly 3 to rotate relative to the handle assembly 2.

[0092] The drive assembly 4 is used to drive the support assembly 3 to rotate relative to the handle assembly 2 along the travel direction X. Therefore, the drive assembly 4 can automatically drive the support assembly 3 to rotate relative to the handle assembly 2, resulting in higher automation and better flexibility. The drive assembly 4 includes a drive member 41. Exemplarily, the drive member 41 can be a motor, rotary cylinder, or other drive member that outputs rotational power, or an electric telescopic cylinder, pneumatic / hydraulic telescopic cylinder, or other drive member that outputs linear power. As a specific example, the drive member 41 can be a servo motor, which has high precision and fast response speed.

[0093] In this embodiment, the drive element 41 of the drive assembly 4 is fixed to the handle base 21. In some other embodiments, the drive element 41 of the drive assembly 4 may also be located in the handle support 22. This embodiment does not specifically limit the position of the drive element 41 of the drive assembly 4, and can be set according to the actual situation. In some embodiments, the drive element 41 may also be mounted on the support assembly 3, such as the support body 31.

[0094] In some embodiments of this application, the cleaning device 100 includes a detection component (not shown) and a controller (not shown). The detection component is disposed on the handle assembly 2 and is used to detect the tilt angle θ of the handle assembly 2 relative to the working surface 10 in a direction away from the cleaning base 1 along the travel direction X of the cleaning base 1. The controller is communicatively connected to the drive assembly 4 and the detection component and is used to control the rotation angle of the support assembly 3 relative to the handle assembly 2 in a direction away from the cleaning base 1 based on the tilt angle θ, so that the support assembly 3 is supported on the working surface 10.

[0095] Therefore, the rotation of the support component 3 relative to the handle component 2 can be controlled automatically by the detection component and controller, resulting in a higher degree of automation and better reliability.

[0096] In this embodiment, the tilt angle θ can be the angle between the axis of the handle assembly 2 tilted relative to the working surface 10 in a direction away from the cleaning base 1 and the vertical axis, or it can be the angle between the axis of the handle assembly 2 tilted relative to the working surface 10 in a direction away from the cleaning base 1 and the working surface 10. For ease of demonstration, the following description will use the example of the tilt angle θ being the angle between the axis of the handle assembly 2 tilted relative to the working surface 10 in a direction away from the cleaning base 1 and the vertical axis. Those skilled in the art should understand that the tilt angle θ being the angle between the axis of the handle assembly 2 tilted relative to the working surface 10 in a direction away from the cleaning base 1 and the working surface 10 is also within the scope of protection of this application.

[0097] The detection component is connected to the controller and the drive component 4, and can transmit the rotation angle information of the handle component 2 detected by the detection component to the controller in a timely manner, so that the controller can control the drive component 4 to drive the support component 3 to rotate relative to the handle component 2.

[0098] For example, the detection component can be electrically connected to the controller and drive component 4, via Bluetooth, antenna signal connection, or WiFi connection, etc. This application does not specifically limit the connection method between the detection component and the drive component 4; any connection method that enables information transmission is within the scope of protection of this application.

[0099] For example, when the detection component detects that the tilt angle θ is greater than the preset angle, the controller will control the drive component 4 based on the angle information transmitted by the detection component, so that the support component 3 rotates relative to the handle component 2.

[0100] In this embodiment, the preset angle can be, for example, 15°. That is, when the handle assembly 2 is tilted at 15° or more relative to the working surface 10, the controller controls the drive assembly 4 to drive the support assembly 3 to rotate relative to the handle assembly 2. Those skilled in the art will understand that in some other embodiments, the preset angle can also be any other angle.

[0101] Furthermore, the controller can control the rotation angle of the drive assembly 4 relative to the support assembly 3 as the tilt angle θ increases, so that the support wheel 32 can maintain contact with the working surface 10. In this way, regardless of the tilt angle θ, good support can be provided for the handle assembly 2, thereby improving the user experience.

[0102] For example, the detection component of the cleaning device 100 can detect the tilt angle θ of the handle assembly 2 in real time. The controller can automatically control the rotation angle of the support component 3 relative to the handle assembly 2 in real time based on the tilt angle θ detected by the detection component. That is, when the tilt angle θ of the handle assembly 2 increases, the controller controls the rotation angle of the support component 3 relative to the handle assembly 2 to increase. When the tilt angle θ of the handle assembly 2 decreases, the controller controls the rotation angle of the support component 3 relative to the handle assembly 2 to decrease, thereby providing good support for the handle assembly 2.

[0103] In this embodiment, the detection component includes a gyroscope sensor. The gyroscope sensor can measure the rotation state in real time and provides faster feedback, thus enabling the drive component 4 to drive the support component 3 to rotate more promptly. Furthermore, the gyroscope sensor offers high detection accuracy, small size, light weight, and strong environmental adaptability.

[0104] Of course, those skilled in the art will understand that in some other embodiments, the detection component can be any other suitable detection component, such as an angle sensor, an inertial sensor, an accelerometer, etc. Any detection component capable of detecting the tilt angle θ of the handle assembly 2 relative to the working surface 10 is within the scope of protection of this application.

[0105] The detection component can directly detect the tilt angle θ. It can also detect the orientation of the handle assembly 2 relative to a reference coordinate system. The controller then calculates the tilt angle θ based on the data detected by the detection component.

[0106] In some embodiments of this application, such as Figure 4 and Figure 5 As shown, the drive assembly 4 includes a drive member 41, a rope 421, and an elastic member 43. The drive member 41 is disposed on the handle assembly 2. One end of the rope 421 is wound around the drive end of the drive member 41, and the other end is connected to the support assembly 3. One end of the elastic member 43 is connected to the support assembly 3, and the other end is connected to the handle assembly 2. The elastic member 43 causes the support assembly 3 to tend to move away from the handle assembly 2.

[0107] Specifically, the drive assembly 4 may further include a take-up member 42. The take-up member 42 is connected to the drive end of the drive member 41 and can rotate under the drive of the drive member 41. One end of the rope 421 is wound around the take-up member 42, and the other end is connected to the support assembly 3. The rope 421 can be wound or unwound under the rotation of the take-up member 42. When the rope 421 is wound up under the rotation of the take-up member 42, the support assembly 3 moves relative to the handle assembly 2 towards the handle assembly 2 and the cleaning base 1. When the rope 421 is unwound under the rotation of the take-up member 42, the support assembly 3 rotates relative to the handle assembly 2 away from the handle assembly 2 and the cleaning base 1.

[0108] The winding member 42 is an assembly used for winding or unwinding the rope 421. As a specific example, the winding member 42 can be a cable reel, and the rope 421 can be a cable.

[0109] In some embodiments, the winding member 42 includes a winding body 422 and a blocking member 423. The winding body 422 is generally cylindrical, and its outer peripheral surface is used to support the rope 421. The rope 421 can be generally wound into a loop and fitted onto the outer peripheral surface of the winding body 422. The winding body 422 can rotate along the rotation axis under the drive of the drive member 41, thereby unwinding or winding the rope 421 wrapped around its outer peripheral surface. There are two blocking members 423, which are located on opposite sides of the winding body 422 along its axial direction. The blocking members 423 have a generally circular cross-section, and their diameter is larger than that of the winding body 422, thereby reducing the possibility of the rope 421 wrapped around the winding body 422 slipping off the winding body 422.

[0110] Of course, those skilled in the art will understand that in some other embodiments, the winding body 422 may also be prismatic or any other suitable shape. The cross-sectional shape of the blocking member 423 may also be square, rectangular, polygonal or any other suitable shape. This application does not specifically limit the shapes of the winding body 422 and the blocking member 423; any solution that enables the winding and unwinding of the rope 421 and reduces the possibility of the rope 421 falling off the winding body 422 is within the scope of protection of this application. Furthermore, in some embodiments, the winding member 42 may not include the blocking member 423.

[0111] Those skilled in the art will understand that the drive assembly 4 may also exclude the winding member 42. One end of the rope 421 may be directly wound around the drive end of the drive member 41, and wound or unwound on the drive end under the drive of the drive member 41.

[0112] One end of the rope 421 is directly or indirectly wrapped around the drive end of the drive member 41, and the other end is connected to the support assembly 3. In the initial state when the support assembly 3 has not rotated relative to the handle assembly 2, the elastic member 43 is in a compressed state between the handle assembly 2 and the support assembly 3.

[0113] When the tilt angle θ of the handle assembly 2 relative to the working surface 10 reaches a preset angle, the controller controls the drive end of the drive member 41 to rotate, thereby unwinding the rope 421 wound on it. At this time, the support assembly 3 can rotate away from the handle assembly 2 under the action of the elastic force applied by the elastic member 43. As the tilt angle θ of the handle assembly 2 increases, more rope 421 is unwound under the rotation of the drive end of the drive member 41, thereby increasing the rotation angle of the support assembly 3 relative to the handle assembly 2.

[0114] Conversely, as the tilt angle θ of the handle assembly 2 relative to the working surface 10 decreases, the drive end of the drive member 41 rotates in the opposite direction, thereby winding up the rope 421. The rope 421 pulls the support assembly 3 to rotate in the direction of travel X toward the handle assembly 2, thereby reducing the rotation angle between the support assembly 3 and the handle assembly 2.

[0115] The rotation of the support assembly 3 relative to the handle assembly 2 is achieved by the cooperation of the rope 421 and the elastic element 43. The structure is simple, the design is ingenious, and the cost of the components is low, which can improve the user experience while reducing the production cost. In addition, the disassembly and assembly of the components are easier, and the replacement is also easier in case of damage.

[0116] Those skilled in the art should understand that the embodiments of this application do not specifically limit the material of the rope, and any suitable rope can be used.

[0117] In this embodiment, the elastic element 43 includes a compression spring. In some other embodiments, the elastic element 43 may be any other suitable elastic element.

[0118] In some embodiments of this application, a connecting portion 33 is formed on the side of the support assembly 3 facing the handle assembly 2. The other end of the rope 421 is connected to the connecting portion 33.

[0119] For example, the other end of the rope 421 may be connected to a buckle. The connecting part 33 may be a locking hole. The rope 421 can be connected to the support component 3 by the snap-fit ​​of the buckle and the locking hole.

[0120] As another example, the other end of the rope 421 may be provided with a first magnetic element. The connecting part 33 may be a second magnetic element with the opposite magnetic properties to the first magnetic element on the rope 421. The connection between the rope 421 and the support assembly 3 is achieved through the magnetic attraction between the first and second magnetic elements.

[0121] This application does not specifically limit the type of the connecting part 33, nor does it specifically limit the connection method between the rope 421 and the connecting part 33. Any method that can maintain a stable connection between the rope 421 and the connecting part 33 is within the protection scope of this application. In some other embodiments, the support component 3 may not have a connecting part 33, and the rope 421 may be directly connected to the support component 3 by any suitable method such as adhesive bonding.

[0122] like Figure 5 As shown in this embodiment, the connecting part 33 includes a hook. One end of the rope 421 is wrapped around the driving end of the driving member 41, and the other end is wrapped around the hook, thereby pulling the support assembly 3 to rotate relative to the handle assembly 2.

[0123] Of course, those skilled in the art will understand that in some other embodiments, the connecting portion 33 may be any other suitable connecting structure.

[0124] In some embodiments of this application, the connecting portion 33 is positioned closer to the cleaning base 1 along the axial direction of the support assembly 3, relative to the elastic element 43.

[0125] Since the drive member 41 is located on the handle base 21 near the cleaning base 1, the connecting portion 33 is positioned closer to the drive member 41 than the elastic member 43 along the axial direction of the support assembly 3. This reduces the pulling force required when the rope 421 pulls the support assembly 3, thus lowering the energy consumption of the drive member 41.

[0126] Of course, those skilled in the art will understand that in some other embodiments, the drive element 41 may also be located in any other suitable position.

[0127] In some embodiments of this application, although not shown in the figures, the drive assembly 4 includes a drive member and a linkage assembly. The drive member is disposed on the handle assembly 2. The linkage assembly includes a first link and a second link. One end of the first link is connected to the drive end of the drive member, and the other end is rotatably connected to the second link. The other end of the second link is connected to the support assembly 3.

[0128] Therefore, the linkage assembly can open or close under the drive of the drive component, thereby causing the support assembly 3 to rotate relative to the handle assembly 2.

[0129] Linkage assemblies are simple in shape, easy to manufacture, and low in cost. They also offer high motion reliability, long transmission distance, and high design flexibility, enabling the realization of different motion laws and trajectories to meet various application requirements.

[0130] Specifically, the driving component can drive the first link to rotate relative to the handle assembly 2, thereby causing the second link to rotate relative to the first link, and in turn causing the support assembly 3 to rotate relative to the handle assembly 2, thereby realizing the opening or closing of the support assembly 3 relative to the handle assembly 2.

[0131] In some embodiments, the driving end of the driving component can also be directly connected to the first rotating shaft 71 of the support component 3 to drive the first rotating shaft 71 to rotate.

[0132] Therefore, the first rotating shaft 71 can be directly driven to rotate by the drive component, thereby realizing the rotation of the support component 3 relative to the handle component 2, and the structure is simpler.

[0133] In some embodiments, the drive assembly may further include a linear drive mechanism. The two ends of the linear drive mechanism are rotatably connected to the handle assembly 2 and the support assembly 3, respectively. Exemplarily, the linear drive mechanism may include an electric actuator. The telescopic end of the electric actuator is connected to the support assembly 3, thereby enabling the support assembly 3 to move relative to the handle assembly 2 toward or away from the handle assembly 2 under the extension and retraction of the electric actuator.

[0134] In some embodiments, the support component 3 is slidably connected to the side of the handle component 2 away from the cleaning base 1, and can move relative to the handle component 2 in a direction away from or towards the working surface 10 at a preset angle.

[0135] Exemplarily, in some embodiments, the driving device may include a driving member and a guide rail slider assembly. The guide rail slider assembly is located on the side of the handle assembly 2 opposite to the cleaning base 1. The guide rail extends along the extending direction of the handle assembly 2, and the slider is supported on the guide rail and can reciprocate along the guide rail. The support assembly 3 may be connected to the slider at a preset angle. The driving end of the driving member is connected to the slider and is used to drive the slider to move linearly on the guide rail. Thus, when the handle assembly 2 tilts away from the cleaning base 1 in the travel direction X, the driving member can drive the slider to move along the guide rail, thereby enabling the support assembly 3 to move closer to the working surface 10 at a preset angle and be supported on the working surface 10.

[0136] The cleaning device 100 may include a detection component and a controller. Both the detection component and the drive unit are communicatively connected to the controller. The detection component can detect the tilt angle of the handle assembly 2 and send the tilt angle information to the controller. The controller can control the drive unit to drive the slider along the guide rail in the direction and distance of movement based on the tilt angle of the handle assembly 2 detected by the detection component and the preset angle of connection between the support assembly 3 and the slider, so that the support assembly 3 can support the working surface 10 when the handle assembly 2 tilts away from the cleaning base 1 in the X direction of travel.

[0137] This application embodiment does not specifically limit the preset angle of connection between the support component 3 and the slider, but can set it according to the actual situation.

[0138] In some embodiments, the support assembly 3 may also be rotatably connected to the slider. Thus, the slider can reciprocate between only two positions (a first position and a second position). When the slider is in the first position, as the tilt angle of the handle assembly 2 relative to the working surface 10 changes, the support assembly 3 can maintain contact with the working surface 10 through rotation relative to the slider. When the slider is in the second position, the support assembly 3 does not contact the working surface 10.

[0139] As an example, the driving device may include a driving member and a lead screw and nut assembly. The lead screw and nut assembly is located on the side of the handle assembly 2 opposite to the cleaning base 1. The lead screw extends along the extension direction of the handle assembly 2, and the nut is fitted onto the lead screw and can reciprocate linearly with the rotation of the lead screw. The support assembly 3 may be connected to the nut at a preset angle or rotatably connected to the nut. The driving end of the driving member is connected to the lead screw and is used to drive the lead screw to rotate. The nut can reciprocate along the lead screw under the rotation of the lead screw, thereby causing the support assembly 3 to slide relative to the handle assembly 2 in a direction away from or towards the working surface 10.

[0140] This application does not specifically limit the sliding connection method between the support component 3 and the handle component 2. Any other suitable sliding connection method can be used, as long as the support component 3 can be supported on the working surface 10 when the handle component 2 is tilted away from the cleaning base 1 in the X direction of travel. All such methods are within the protection scope of this application.

[0141] In some embodiments of this application, the cleaning device 100 further includes an energy component 5 and a water tank 6. The energy component 5 is disposed on the support component 3, and / or, the water tank 6 is disposed on the support component 3.

[0142] The energy component 5 can be a battery, a photovoltaic panel, or a device that uses fuel to provide energy. In this embodiment, the energy component 5 includes a battery housed inside the support body 31. Figure 6The dashed line in the diagram schematically shows the energy component 5, indicating that the energy component 5 is located inside the support body 31.

[0143] In the embodiments of this application, such as Figure 6 As shown, both the water tank 6 and the energy component 5 are mounted on the support body 31. The mounting of both the water tank 6 and the energy component 5 on the support body 31 helps reduce the weight of the handle assembly 2, making it easier for the user to hold the handle assembly 2 for cleaning operations and further improving the user experience.

[0144] Of course, those skilled in the art should understand that in some other embodiments, only the energy component 5 may be disposed on the support component 3, or only the water tank 6 may be disposed on the support component 3, or neither the energy component 5 nor the water tank 6 may be disposed on the support component 3.

[0145] The water tank 6 can be either a clean water tank or a wastewater tank. In this embodiment, the water tank 6, which is mounted on the support assembly 3, is a clean water tank, and the wastewater tank 221 is mounted on the handle assembly 2. In some other embodiments, the wastewater tank may be mounted on the support assembly 3, and the clean water tank may be mounted on the handle assembly 2.

[0146] A second aspect of this application provides a cleaning system, which includes the cleaning device 100 described in the first aspect of this application and a base station. The base station supports the cleaning device 100 and provides power to the cleaning device 100.

[0147] For example, after the cleaning device 100 completes its cleaning task, it can return to the base station. The base station can be used, for example, to charge the cleaning device 100, clean and dry the cleaning roller brush 11 of the cleaning device 100, etc.

[0148] As a concrete example, the cleaning device 100 includes a handle (handle assembly 2) and support wheels (support assembly 3). When the built-in gyroscope sensor (detection assembly) detects a change in the handle's tilt angle in real time, it activates the motor (drive component 41). By controlling the tension of the cable (rope 421), and in conjunction with the spring (elastic component 43), it controls the opening angle of the support wheels, allowing the support wheels to provide support. This system can dynamically adjust the opening phase and supporting torque of the support wheels based on the tilt angle data, forming an adaptive balance solution based on angle feedback, effectively enhancing the operational stability and support performance of the cleaning device under tilted conditions.

[0149] With the handle stationary and upright, the support wheel contacts the ground (working surface 10). When the handle is tilted to 15°, the support wheel begins to open. A cable reel (winding component 42) is connected to a motor, controlling its rotation. The rotation of the cable reel controls the tension of the cable. One end of the cable is attached to the cable reel, and the other end is attached to the hook (connecting part 33) of the support wheel.

[0150] The support wheel and handle have two degrees of freedom, allowing the support wheel to rotate relative to the handle in the forward / backward direction (X-direction) and the left / right direction (first direction Y). Under normal operating conditions, when the handle is tilted, it can rotate left / right. To ensure smooth left / right rotation of the handle, the support wheel and handle have a degree of freedom in the left / right direction so that the support wheel does not rotate when it is supporting the ground.

[0151] A battery (energy component 5) and / or a water tank 6 can be installed on the support wheel. The support wheel is in contact with the ground and provides support. This arrangement ensures that the weight of the battery and water tank is distributed on the support wheel rather than the handle, reducing the weight of the handle.

[0152] The above embodiments are merely illustrative of the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application, and all should be covered within the scope of this application. In particular, as long as there is no structural conflict, the various technical features mentioned in the embodiments can be combined in any way.
