Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and more particularly to a support assembly, a tracked cleaning assembly, and a cleaning device. Background Technology

[0002] Most current robotic vacuum cleaners have a mopping function, which is achieved by installing a mopping module on the bottom of the robot. This module performs the mopping function. Mopping modules are broadly categorized into three types based on their form: disc-type mopping modules, roller-type mopping modules, and tracked mopping modules. Among these, tracked mopping modules offer advantages over disc-type and roller-type modules, including a larger mopping area, stronger pressure on the floor, and a better, more thorough mopping finish.

[0003] Typically, a tracked mop assembly includes a mop holder and a mop. The mop is positioned on the outside of the mop holder, and the tracked mop assembly is mounted on the robotic vacuum cleaner via the mop holder. In related technologies, a certain tension exists between the mop holder and the mop in the tracked mop assembly. Under this tension, the mop holder drives the mop to move, thus achieving the mopping function. After a period of use, the user needs to remove the mop from the mop holder for washing or replacement.

[0004] However, the tension between the cloth holder and the cloth makes it difficult to assemble and disassemble the cloth. Utility Model Content

[0005] This application provides a support assembly, a tracked cleaning assembly, and a cleaning device to solve the problem in the aforementioned related technologies where the installation and removal of the wiping cloth is difficult due to the tension between the wiping cloth support and the wiping cloth.

[0006] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0007] A first aspect of this application provides a support assembly, including:

[0008] The first support extends along the first direction;

[0009] A second support extends along the first direction, and the second support and the first support are arranged side by side in the second direction. The second support and the first support are rotatably connected, and the rotation axes of the first support and the second support are parallel to the first direction, while the second direction is perpendicular to the first direction.

[0010] The support assembly includes a flattened state and a folded state. When the support assembly is in the flattened state, the first support and the second support are located on the same plane. When the support assembly is folded from the flattened state to the folded state, the distance between the two opposite ends of the first support and the second support is reduced.

[0011] The bracket assembly in this embodiment forms a hinged connection between the first and second brackets by rotating them together. This allows the distance between the opposite ends of the first and second brackets to be changed by folding or flattening the bracket assembly. For example, when it's necessary to remove a cloth from the tracked cleaning assembly, the bracket assembly can be folded to reduce the distance between the opposite ends of the first and second brackets, thus loosening the cloth and facilitating its removal. Similarly, when installing a cloth on the bracket assembly, it can be folded first, the cloth placed on it, and then flattened to support the cloth and create tension for cleaning operations.

[0012] By rotating the second bracket to connect it to the first bracket, the assembly difficulty between the first and second brackets can be reduced, thereby improving assembly efficiency.

[0013] In one possible implementation, the support assembly further includes at least one connecting shaft; wherein,

[0014] The connecting shaft extends along a first direction and is disposed between the first bracket and the second bracket. The first bracket and the second bracket are rotatably connected by the connecting shaft.

[0015] When there are multiple connecting shafts, the multiple connecting shafts are set sequentially along the first direction.

[0016] By using a connecting shaft, the first and second supports can rotate relative to each other. The connecting shaft provides a stable fulcrum for rotation, improving the connection stability between the first and second supports. Using the connecting shaft simplifies the design of the support assembly, reducing the need for additional connectors or complex structures. This reduces manufacturing costs and assembly complexity.

[0017] In one possible implementation, the first bracket includes a first limiting portion, and the second bracket includes a second limiting portion that matches the first limiting portion; wherein...

[0018] When the bracket assembly is opened from the folded state to the flattened state, the first limiting part and the second limiting part abut against each other to prevent the first bracket and the second bracket from folding in opposite directions;

[0019] When the bracket assembly is folded from the flat state to the folded state, the first limiting part and the second limiting part abut against each other to prevent the first bracket and the second bracket from continuing to fold.

[0020] By incorporating a first and a second limiting part, the first and second supports can be prevented from exceeding a predetermined angle during folding, thus avoiding mechanical damage caused by excessive folding. When the support assembly is unfolded to its flattened state, the contact between the first and second limiting parts ensures the stability of the assembly. By restricting reverse folding, the support assembly remains stable during use, providing reliable support and improving overall safety. The presence of the first and second limiting parts allows users to operate the support assembly without excessive focus on the folding angle, simplifying the process and enhancing the user experience. By preventing excessive folding and unnecessary stress, the first and second limiting parts reduce wear and fatigue on the support assembly, thereby extending its service life.

[0021] In one possible implementation, the first limiting part includes an adjacent first limiting surface and a second limiting surface, which are arranged at an angle.

[0022] The second limiting part includes a third limiting surface and a fourth limiting surface that are adjacent to each other, and the third limiting surface and the fourth limiting surface are arranged at an angle.

[0023] When the bracket assembly is opened from the folded state to the flattened state, the first limiting surface abuts against the third limiting surface to restrict the first bracket and the second bracket from folding in opposite directions;

[0024] When the bracket assembly folds from the flat state to the folded state, the second limiting surface abuts against the fourth limiting surface to prevent the first bracket and the second bracket from continuing to fold.

[0025] By configuring both the first and second limiting parts with two adjacent limiting surfaces (first and second limiting surfaces, and third and fourth limiting surfaces), bidirectional limiting can be provided under different operating conditions. This effectively restricts the angle of the support assembly during unfolding and folding, preventing excessive movement and accidental over-folding or unfolding, thereby reducing equipment damage and improving overall safety. In the flattened state, the contact between the first and third limiting surfaces provides stable support and prevents reverse folding. In the folded state, the contact between the second and fourth limiting surfaces prevents further folding, ensuring the support assembly remains stable in both states. The stress dispersion through the contact between the limiting surfaces reduces wear and stress concentration at single contact points. This extends the service life of the support assembly and improves its durability.

[0026] In one possible implementation, in the second direction, the first limiting part is located on the side of the first bracket facing the second bracket, and the second limiting part is located on the side of the second bracket facing the first bracket.

[0027] This arrangement allows for a more efficient placement of the first and second limiting parts between the first and second supports, reducing external protrusions and resulting in a more compact and aesthetically pleasing design. The first and second limiting parts are located on opposite sides of the first and second supports, providing better mechanical support when the support assembly is unfolded or folded, enhancing the overall structural strength and stability. This design simplifies the structure of the first and second supports, reducing the need for additional connectors or complex assembly steps.

[0028] In one possible implementation, when the support assembly is in the folded state, the included angle between the first support and the second support is between 45° and 160°.

[0029] By setting the included angle range to 45°-160°, a wide range of usage angles can be provided for the bracket assembly to adapt to different application needs. Users can adjust the angle of the bracket according to specific needs to obtain the best user experience. In addition, when the included angle between the first and second brackets is between 45° and 160°, the distance between the opposite ends of the first and second brackets is reduced, which allows the cloth on the bracket to be loosened, making it easier to remove the cloth from the bracket assembly. Of course, it also makes it easier to install a clean cloth on the bracket assembly.

[0030] In one possible implementation, when the support assembly is in the folded state, the included angle between the first support and the second support is between 50° and 80°.

[0031] In one possible implementation, when the support assembly is in the folded state, the included angle between the first support and the second support is 60° or 70°.

[0032] In one possible implementation, one of the first bracket and the second bracket is provided with a first locking part, and the other of the first bracket and the second bracket is provided with a second locking part that cooperates with the first locking part.

[0033] The first locking part is used to lock and connect with the second locking part when the bracket assembly is in a flattened state.

[0034] By incorporating a first locking part and a second locking part, the support assembly can be ensured to remain stable in the flattened state, preventing accidental folding or movement due to external forces or vibrations, thus improving operational stability. Furthermore, it allows users to easily secure the support assembly in the flattened state without additional tools or complex procedures, enhancing ease of operation.

[0035] In one possible implementation, one of the first locking part and the second locking part is a boss structure, and the other of the first locking part and the second locking part is a groove structure;

[0036] When the bracket assembly is in a flattened state, the boss structure and the groove structure engage and connect.

[0037] When the bracket assembly folds from the flat state to the folded state, the boss structure and the groove structure disengage.

[0038] This design simplifies the structure of the first and second locking parts, thereby simplifying the structure of the bracket assembly and reducing costs.

[0039] In one possible implementation, the support assembly includes an active rotation axis and a driven rotation axis; wherein,

[0040] The active rotating shaft is sleeved on the side of the first bracket away from the second bracket, and the active rotating shaft is rotatably connected to the first bracket;

[0041] The driven rotating shaft is sleeved on the side of the second bracket away from the first bracket, and the driven rotating shaft is rotatably connected to the second bracket.

[0042] With this configuration, when the support assembly is applied to the tracked cleaning assembly, the coordinated operation of the active and driven rotating shafts allows power to be effectively transmitted to the cloth sleeved on the outside of the support assembly, ensuring that the cloth can move smoothly and efficiently, thus improving cleaning efficiency.

[0043] In one possible implementation, the active rotating shaft includes a first support section and a first recessed section that are alternately arranged along the axial direction, wherein the diameter of the first recessed section is smaller than that of the first support section;

[0044] The first bracket is provided with at least one first limiting boss, which is disposed opposite to the first inward section, and part of the structure of the first limiting boss extends to the inner side of the outer contour of the first support section.

[0045] This configuration, through the cooperation of the first limiting boss and the first inward section, prevents the active rotating shaft from wobbling radially, thereby improving the stability of the bracket assembly.

[0046] In one possible implementation, the first support segment is made of soft rubber, and the first inward segment is made of non-soft rubber.

[0047] By making the first support section a soft rubber material, the friction between the active rotating shaft and the cloth is increased when the cloth is sleeved on the bracket assembly, allowing the active rotating shaft to move the cloth. By making the first recessed section a non-soft rubber material, noise can be prevented from being generated by the first limiting boss contacting the soft rubber material.

[0048] In one possible implementation, the driven rotating shaft includes a second support section and a second recessed section arranged alternately along the axial direction, wherein the diameter of the second recessed section is smaller than that of the second support section;

[0049] The second bracket is provided with at least one second limiting boss, the second limiting boss is disposed opposite to the second inward section, and part of the structure of the second limiting boss extends to the inner side of the outer contour of the second support section.

[0050] The second support section and the second inward-curving section are both made of non-soft rubber material.

[0051] This design prevents the driven rotating shaft from wobbling radially, improving the stability of the support assembly. By using non-soft rubber materials for both the second support section and the second recessed section, the structure of the driven rotating shaft can be simplified, thereby reducing costs and also reducing noise between the second limiting boss and the driven rotating shaft.

[0052] A second aspect of this application provides a tracked cleaning assembly, including a cloth and a support assembly as described in any of the first aspects above; wherein,

[0053] The cloth is fitted over the outside of the bracket assembly, and the cloth is detachably connected to the bracket assembly.

[0054] When the support assembly is in a flattened state, there is tension between the cloth and the support assembly.

[0055] By setting up the first aspect of the support assembly, when it is necessary to remove the cloth, the support assembly can be folded so that the two opposite ends of the support assembly are brought together, thereby making the cloth on the support assembly loose, so that the cloth assembly can be removed from the support assembly.

[0056] A third aspect of this application provides a cleaning device, including a device body and a tracked cleaning component as described in the second aspect. Attached Figure Description

[0078] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0079] With the development of automatic cleaning equipment, robotic vacuum cleaners with mopping functions have become widely popular. Generally, the mopping module of a robotic vacuum cleaner can be broadly categorized into three types based on its form: disc-type mopping assembly, roller-type mopping assembly, and tracked mopping assembly. Among these, the tracked mopping assembly offers advantages over disc-type and roller-type mopping assemblies, including a larger mopping area, stronger pressure on the floor, and a more thorough mopping effect.

[0080] A tracked mop assembly typically includes a mop holder and a mop. The mop is positioned on the outside of the mop holder, and the tracked mop assembly is mounted on a robotic vacuum cleaner via the mop holder. In related technologies, a certain tension exists between the mop holder and the mop in the tracked mop assembly. Under this tension, the mop holder drives the mop to move, thus achieving the mopping function. After a period of use, the user needs to remove the mop from the mop holder for washing or replacement.

[0081] However, the tension between the cloth holder and the cloth makes it difficult to assemble and disassemble the cloth. To solve the above technical problem, this application provides a holder assembly. The holder assembly has a simple structure and can be folded to reduce the distance between the two opposite ends of the holder assembly, thereby loosening the cloth on the holder assembly and making it easier to pull the cloth out of the holder assembly.

[0082] The support assembly, tracked cleaning assembly, and cleaning equipment provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0083] Figure 1 This is a schematic diagram of a support assembly provided in an embodiment of this application. Figure 2 This is a schematic diagram of a support assembly in a folded state, provided in an embodiment of this application.

[0084] It should be noted that, for ease of description, in this embodiment, the first direction is referred to as the x-direction, the second direction as the y-direction, and the third direction as the z-direction, with the first, second, and third directions being mutually perpendicular. The third direction can be considered as the thickness direction of the support assembly.

[0085] This application provides a support assembly 100, such as... Figure 1 As shown, the support assembly 100 may include a first support 10 and a second support 20. The first support 10 extends along a first direction (x-direction), and the second support 20 also extends along the first direction (x-direction). The second support 20 and the first support 10 are arranged side-by-side in a second direction (y-direction), and the second support 20 is rotatably connected to the first support 10. The rotation axes of the first support 10 and the second support 20 are parallel to the first direction (x-direction), and the second direction (y-direction) is perpendicular to the first direction (x-direction).

[0086] like Figure 1 and Figure 2 As shown, the support assembly 100 may include a flattened state and a folded state. When the support assembly 100 is in the flattened state, the first support 10 and the second support 20 are located on the same plane. When the support assembly 100 is folded from the flattened state to the folded state, the distance between the two opposite ends of the first support 10 and the second support 20 is reduced.

[0087] For example, the second direction (y direction) can be the forward or backward direction of the cleaning device 400 when the support assembly 100 is applied to the tracked cleaning assembly 200. In other words, the first support 10 and the second support 20 can be arranged back and forth along the moving direction of the cleaning device 400.

[0088] It should be noted that "the rotation axes of the first support 10 and the second support 20 are parallel to the first direction (x direction)" refers to parallelism within a certain error range. That is to say, the rotation axes of the first support 10 and the second support 20 are approximately parallel to the first direction (x direction). For example, if the angle between the rotation axes of the first support 10 and the second support 20 and the first direction (x direction) is within 5°, it can be considered as parallel.

[0089] Similarly, "the first direction (x-direction) is perpendicular to the second direction (y-direction)" means that the first direction (x-direction) and the second direction (y-direction) are approximately perpendicular within a certain error range. For example, the angle between the first direction (x-direction) and the second direction (y-direction) is 90° or close to 90°. For instance, angles between the first direction (x-direction) and the second direction (y-direction) between 85° and 90°, and between 90° and 95°, can be considered as the first direction (x-direction) and the second direction (y-direction) being perpendicular. For example, when the angle between the first direction (x-direction) and the second direction (y-direction) is 85°, 86°, 87°, 88°, 89°, 91°, 92°, 93°, 94°, or 95°, the first direction (x-direction) and the second direction (y-direction) are all perpendicular.

[0090] It should be noted that "the first support 10 and the second support 20 are located in the same plane" means that, under the ideal condition where the thickness of the first support 10 and the second support 20 is essentially zero, the first support 10 and the second support 20 are substantially located in the same plane (see...). Figure 1 (As shown). At this time, the distance between the opposite ends of the first bracket 10 and the second bracket 20 is at its maximum. And when the rag 300 is fitted onto the bracket assembly 100, the surface of the rag 300 is roughly a planar structure, and there are no protrusions or depressions at the connection between the first bracket 10 and the second bracket 20.

[0091] In this embodiment, the bracket assembly 100, by rotatably connecting the first bracket 10 and the second bracket 20, forms a hinged connection structure between the first bracket 10 and the second bracket 20. This allows the distance between the opposite ends of the first bracket 10 and the second bracket 20 to be changed by folding or flattening the bracket assembly 100. For example, this allows the rag 300 on the tracked cleaning assembly 200 to be removed when needed (see [link]). Figure 7 As shown, the support assembly 100 can be adjusted to a folded state, reducing the distance between the opposite ends of the first support 10 and the second support 20. This allows the cloth 300 on the tracked cleaning assembly 200 to become looser, making it easier to remove the cloth 300 from the support assembly 100. Similarly, when it is necessary to install the cloth 300 on the support assembly 100, the support assembly 100 can be first adjusted to a folded state, the cloth 300 can be placed on the support assembly 100, and then the support assembly 100 can be adjusted to a flattened state to support the cloth 300 and achieve a taut state for cleaning operations.

[0092] By rotating the second bracket 20 to the first bracket 10, the assembly difficulty between the first bracket 10 and the second bracket 20 can be reduced, thereby improving assembly efficiency.

[0093] like Figure 3 As shown, the support assembly 100 may further include at least one connecting shaft 30. The connecting shaft 30 extends along a first direction (x-direction) and is disposed between the first support 10 and the second support 20, which are rotatably connected via the connecting shaft 30. When there are multiple connecting shafts 30, they are sequentially arranged along the first direction (x-direction). Exemplarily, the number of connecting shafts 30 may be one, two, three, or more; however, in this embodiment, the number of connecting shafts 30 is not further limited.

[0094] By providing the connecting shaft 30, the first bracket 10 and the second bracket 20 can rotate relative to each other. The connecting shaft 30 provides a stable pivot point, improving the connection stability between the first bracket 10 and the second bracket 20. Using the connecting shaft 30 simplifies the design of the bracket assembly 100, reducing the need for additional connectors or complex structures. This reduces manufacturing costs and assembly complexity.

[0095] It should be noted that when there are multiple connecting shafts 30, the dimensions of the multiple connecting shafts 30 in the first direction (x direction) can be the same or different, as long as they can satisfy the connection relationship between the first bracket 10 and the second bracket 20.

[0096] like Figure 3 As shown, both the first bracket 10 and the second bracket 20 may include a connecting hole through which the connecting shaft 30 passes. The connecting shaft 30 rotatably connects the first bracket 10 and the second bracket 20 by passing through the connecting hole of the first bracket 10 and the second bracket 20.

[0097] See also Figure 2 and Figure 3 As shown, the first support 10 may include a first limiting portion 11, and the second support 20 includes a second limiting portion 21 that matches the first limiting portion 11. When the support assembly 100 is opened from a folded state to a flattened state, the first limiting portion 11 and the second limiting portion 21 abut against each other to prevent the first support 10 and the second support 20 from folding in the opposite direction. When the support assembly 100 is folded from a flattened state to a folded state, the first limiting portion 11 and the second limiting portion 21 abut against each other to prevent the first support 10 and the second support 20 from continuing to fold.

[0098] It should be noted that "reverse folding" refers to folding the component from the folded state to the flattened state, and then folding it in the opposite direction. For example, if the folded state is inward, then reverse folding will cause the support assembly 100 to fold outward. Figure 2 Reverse folding is represented by direction c, and forward folding is represented by direction s.

[0099] By providing the first limiting part 11 and the second limiting part 21, the first bracket 10 and the second bracket 20 can be prevented from exceeding a predetermined angle during the folding process, avoiding mechanical damage caused by excessive folding. When the bracket assembly 100 is unfolded to the flattened state, the contact between the first limiting part 11 and the second limiting part 21 ensures the stability of the bracket assembly 100. By restricting reverse folding, the bracket assembly 100 can remain stable during use, providing reliable support and thus improving overall safety. The presence of the first limiting part 11 and the second limiting part 21 allows users to operate the bracket assembly 100 without having to pay too much attention to the folding angle, simplifying the use process and improving the user experience. By preventing excessive folding and unnecessary stress, the first limiting part 11 and the second limiting part 21 can reduce wear and fatigue on the bracket assembly 100, thereby extending its service life.

[0100] In one possible implementation, in the second direction (y-direction), the first limiting part 11 is located on the side of the first bracket 10 facing the second bracket 20, and the second limiting part 21 is located on the side of the second bracket 20 facing the first bracket 10. That is, the first limiting part 11 and the second limiting part 21 are respectively located on the sides of the first bracket 10 and the second bracket 20 that are close to each other.

[0101] It should be noted that in the embodiments of this application, "orientation" refers to orientation in a broad sense and is not limited to a front-facing arrangement, and "away from" refers to away from in a broad sense and is not limited to a back-to-back parallel arrangement.

[0102] This arrangement allows for a more rational layout of the first limiting part 11 and the second limiting part 21 in the first bracket 10 and the second bracket 20, reducing external protrusions and resulting in a more compact and aesthetically pleasing design. The first limiting part 11 and the second limiting part 21 are located on opposite sides of the first bracket 10 and the second bracket 20, respectively. This arrangement provides better mechanical support when the bracket assembly 100 is unfolded or folded, enhancing the overall structural strength and stability. This design simplifies the structure of the first bracket 10 and the second bracket 20, reducing the need for additional connectors or complex assembly steps.

[0103] See also Figure 2 and Figure 3 As shown, one of the first bracket 10 and the second bracket 20 is provided with a first locking part 12, and the other of the first bracket 10 and the second bracket 20 is provided with a second locking part 24 that cooperates with the first locking part 12. The first locking part 12 is used to lock and connect with the second locking part 24 when the bracket assembly 100 is in a flattened state.

[0104] For example, the locking connection between the first locking part 12 and the second locking part 24 can be a locking connection achieved by a snap-fit ​​part, or a locking connection achieved by friction. The locking relationship can be directly broken by external force, and the locking relationship can be achieved by external force. In this embodiment, the locking method between the first locking part 12 and the second locking part 24 is not further limited.

[0105] By providing the first locking part 12 and the second locking part 24, the bracket assembly 100 can be ensured to remain stable in the flattened state, preventing accidental folding or movement due to external forces or vibrations, thereby improving the stability of the working state. Furthermore, it allows users to easily fix the bracket assembly 100 in the flattened state without additional tools or complicated operating procedures, improving ease of operation.

[0106] In one possible implementation, one of the first locking portion 12 and the second locking portion 24 is a boss structure, and the other of the first locking portion 12 and the second locking portion 24 is a groove structure. When the bracket assembly 100 is in a flattened state, the boss structure and the groove structure are engaged. When the bracket assembly 100 is folded from the flattened state to a folded state, the boss structure and the groove structure are disengaged. The boss structure and the groove structure can be engaged through friction, wherein when the boss structure and the groove structure are engaged, the boss structure is located within the groove structure and is interference-fitted with the groove structure.

[0107] This configuration simplifies the structure of the first locking part 12 and the second locking part 24, thereby simplifying the structure of the bracket assembly 100 and reducing costs.

[0108] See also Figure 3 As shown, the support assembly 100 may include an active rotation shaft 13 and a driven rotation shaft 22. The active rotation shaft 13 is sleeved on the side of the first support 10 opposite to the second support 20, and is rotatably connected to the first support 10. The driven rotation shaft 22 is sleeved on the side of the second support 20 opposite to the first support 10, and is rotatably connected to the second support 20.

[0109] It should be noted that the axial directions of the active rotating shaft 13, the driven rotating shaft 22, and the connecting shaft 30 are all parallel to each other.

[0110] This configuration is used when the support assembly 100 is applied to the tracked cleaning assembly 200 (see...). Figure 8 As shown, the coordinated operation of the active rotating shaft 13 and the driven rotating shaft 22 can effectively transmit power to the wiping cloth 300 sleeved on the outside of the bracket assembly 100, ensuring that the wiping cloth 300 can move smoothly and efficiently, thus improving cleaning efficiency.

[0111] See also Figure 3 As shown, the active rotating shaft 13 may include a first support section 131 and a first recessed section 132 alternately arranged along the axial direction (x direction), wherein the diameter of the first recessed section 132 is smaller than that of the first support section 131. The first bracket 10 is provided with at least one first limiting boss 14, which is disposed opposite to the first recessed section 132. A portion of the structure of the first limiting boss 14 extends to the inner side of the outer contour of the first support section 131 (see...). Figure 1 (As shown).

[0112] The driven rotating shaft 22 may include a second support section 221 and a second recessed section 222 alternately arranged along the axial direction (x direction), wherein the diameter of the second recessed section 222 is smaller than that of the second support section 221. The second bracket 20 is provided with at least one second limiting boss 23, which is disposed opposite to the second recessed section 222, and a portion of the structure of the second limiting boss 23 extends to the inner side of the outer contour of the second support section 221.

[0113] It should be noted that when the wiping cloth 300 is fitted onto the bracket assembly 100, the first support section 131 and the second support end are used to contact and connect with the wiping cloth 300. The active rotating shaft 13 can apply a certain driving force to the wiping cloth 300 to drive the wiping cloth 300 to move relative to the bracket assembly 100.

[0114] By configuring the active rotating shaft 13 to include a first support section 131 and a first retractable section 132, and configuring the driven rotating shaft 22 to include a second support section 221 and a second retractable section 222, and by providing a first limiting boss 14 on the first bracket 10 and a second limiting boss 23 on the second bracket 20, the active rotating shaft 13 can be prevented from wobbling radially by the cooperation of the first limiting boss 14 and the first retractable section 132, and the driven rotating shaft 22 can be prevented from wobbling radially by the cooperation of the second limiting boss 23 and the second retractable section 222, thereby improving the stability of the bracket assembly 100.

[0115] In one possible implementation, the first support segment 131 is made of soft rubber, and the first recessed segment 132 is made of non-soft rubber. The second support segment 221 and the second recessed segment 222 are both made of non-soft rubber.

[0116] For example, the soft rubber material can be silicone, thermoplastic elastomer, polyurethane, neoprene rubber, etc. The non-soft rubber material can be plastic or rigid plastic, etc. In this embodiment of the application, the materials of the active rotating shaft 13 and the driven rotating shaft 22 are not further limited, and can be set according to actual needs.

[0117] By making the first support section 131 a soft rubber material, the friction between the active rotating shaft 13 and the cloth 300 is increased when the cloth 300 is fitted onto the bracket assembly 100, allowing the active rotating shaft 13 to drive the cloth 300 to move. By making the first recessed section 132 a non-soft rubber material, noise caused by contact between the first limiting boss 14 and the soft rubber material can be prevented. By making both the second support section 221 and the second recessed section 222 non-soft rubber materials, the structure of the driven rotating shaft 22 can be simplified, thereby reducing costs, and noise between the second limiting boss 23 and the driven rotating shaft 22 can also be reduced.

[0118] The first limiting part 11 and the second limiting part 21 will be described in detail below with reference to the accompanying drawings.

[0119] like Figure 4 As shown, the first limiting part 11 may include a first limiting surface 111 and a second limiting surface 112 that are adjacent to each other, and the first limiting surface 111 and the second limiting surface 112 are arranged at an included angle. Figure 5 As shown, the second limiting part 21 may include a third limiting surface 211 and a fourth limiting surface 212 adjacent to each other, and the third limiting surface 211 and the fourth limiting surface 212 are arranged at an angle. When the bracket assembly 100 is opened from the folded state to the flattened state, the first limiting surface 111 abuts against the third limiting surface 211 (see...). Figure 6 (as shown), to restrict the first support 10 and the second support 20 from folding in opposite directions. When the support assembly 100 folds from the flattened state to the folded state, the second limiting surface 112 abuts against the fourth limiting surface 212 (see...). Figure 7 (As shown), to limit the first support 10 and the second support 20 from continuing to fold.

[0120] It should be noted that, in this embodiment, the included angle between the first limiting surface 111 and the second limiting surface 112 is not limited. For example, the included angle between the first limiting surface 111 and the second limiting surface 112 can be between 100° and 160°. The included angle between the third limiting surface 211 and the fourth limiting surface 212 can be set close to 90°, specifically based on the included angle between the first support 10 and the second support 20 in the folded state. In this embodiment, the included angle between the first limiting surface 111 and the second limiting surface 112, and the included angle between the third limiting surface 211 and the fourth limiting surface 212 are not further limited.

[0121] By configuring both the first limiting part 11 and the second limiting part 21 with two adjacent limiting surfaces (first limiting surface 111 and second limiting surface 112, and third limiting surface 211 and fourth limiting surface 212), bidirectional limiting can be provided in different operating states. This allows the bracket assembly 100 to be effectively limited in angle during unfolding and folding, preventing excessive movement and accidental over-folding or unfolding, thereby reducing equipment damage and improving overall safety. In the flattened state, the contact between the first limiting surface 111 and the third limiting surface 211 provides stable support and prevents reverse folding. In the folded state, the contact between the second limiting surface 112 and the fourth limiting surface 212 prevents further folding, ensuring that the bracket assembly 100 remains stable in both states. By dispersing stress through the contact between the limiting surfaces, wear and stress concentration at a single contact point can be reduced. This can extend the service life of the bracket assembly 100 and improve its durability.

[0122] As an explanation, the distance from the center of the active rotation shaft 13 to the center of the connecting shaft 30 is fixed at L1, and the distance from the center of the driven rotation shaft 22 to the center of the connecting shaft 30 is fixed at L2. The distance from the center of the active rotation shaft 13 to the center of the driven rotation shaft 22 is a variable L3.

[0123] like Figure 6 As shown, when the support assembly 100 is in a flattened state, L3 is the sum of L2 and L1. Figure 7 As shown, when the support assembly 100 is in the folded state, the line connecting the axis of the active rotation axis 13, the axis of the connecting axis 30, and the axis of the driven rotation axis 22 forms a triangle, where L3 is less than the sum of L2 and L1.

[0124] When the same cloth 300 is placed on the bracket assembly 100, the cloth 300 is more fluffy when the bracket assembly 100 is folded up compared to when it is flat. This means that when the cloth 300 is folded up, there is almost no tension between the cloth 300 and the bracket assembly 100, so it is easy to install and remove the bracket assembly 100 and the cloth 300.

[0125] For example, such as Figure 7 As shown, when the bracket assembly 100 is in the folded state, the included angle between the first bracket 10 and the second bracket 20 can be the angle between the line connecting the connecting shaft 30 and the active rotation shaft 13 and the line connecting the connecting shaft 30 and the driven rotation shaft 22, which is represented as α in the figure.

[0126] By setting the included angle range to 45°-160°, a wide range of usage angles can be provided for the bracket assembly 100 to adapt to different application needs. Users can adjust the angle of the bracket according to specific needs to obtain the best user experience. In addition, when the included angle between the first bracket 10 and the second bracket 20 is between 45° and 160°, the distance between the opposite ends of the first bracket 10 and the second bracket 20 is reduced, which allows the cloth 300 located on the bracket to be loosened, thereby facilitating the removal of the cloth 300 from the bracket assembly 100. Of course, it also makes it easier to install a clean cloth 300 on the bracket assembly 100.

[0127] In some embodiments, when the bracket assembly 100 is in a folded state, the included angle α between the first bracket 10 and the second bracket 20 can be between 50° and 80°.

[0128] In some other embodiments, when the support assembly 100 is in a folded state, the included angle α between the first support 10 and the second support 20 can be 60° or 70°.

[0129] In some embodiments, when the bracket assembly 100 is in a folded state, the included angle α between the first bracket 10 and the second bracket 20 can be 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, 90°, 95°, 100°, 105°, 110°, 115°, 120°, 125°, 130°, 135°, 140°, 145°, 150°, 155°, 160°, etc. In this embodiment, the specific value of the included angle α between the first bracket 10 and the second bracket 20 is not further limited, and can be set according to specific requirements.

[0130] This application embodiment also provides a tracked cleaning assembly 200, such as Figure 8 As shown, the tracked cleaning assembly 200 may include a cloth 300 and a support assembly 100 as described in any of the first aspects above. The cloth 300 is sleeved on the outside of the support assembly 100, and the cloth 300 is detachably connected to the support assembly 100. When the support assembly 100 is in a flattened state, there is tension between the cloth 300 and the support assembly 100.

[0131] By providing the first aspect of the support assembly 100, when it is necessary to remove the cloth 300, the support assembly 100 can be folded so that the two opposing ends of the support assembly 100 are brought closer together, thereby making the cloth 300 on the support assembly 100 slack, so that the cloth 300 assembly can be removed from the support assembly 100.

[0132] This application embodiment also provides a cleaning device 400, such as... Figure 9As shown, the cleaning device 400 may include a device body 500 and a tracked cleaning component 200. The cleaning device 400 can mop the floor using the tracked cleaning component 200. The cleaning device 400 possesses all the advantages of the tracked cleaning component 200.
