Abstract
Description
Technical Field
[0001] The present application relates to the technical field of cleaning equipment, and in particular to a bracket assembly, a crawler-type cleaning assembly and a cleaning equipment. Background Art
[0002] The current sweeping robots usually have the function of mopping the floor, which is mainly achieved by setting a mopping module at the bottom of the sweeping robot and using the mopping module to achieve the mopping function. The mopping module is roughly divided into: disc-type rag assembly, drum-type rag assembly and crawler-type rag assembly according to different product forms. Among them, the crawler-type rag assembly has the advantages of a large mopping area, strong ground pressure, and a mopping effect close to the edge compared to the disc-type and drum-type rag assemblies.
[0003] Generally, the crawler rag assembly includes a rag bracket and a rag, and the rag is arranged on the outside of the rag bracket. The crawler rag assembly is installed on the sweeping robot through the rag bracket. There is a certain tension between the rag bracket and the rag on the crawler rag assembly in the related art. Under the action of the tension, the rag bracket drives the rag to move to achieve the mopping function. After using it for a period of time, the user needs to remove the rag from the rag bracket for cleaning or replacement.
[0004] However, due to the tension between the rag support and the rag, it is difficult to disassemble and assemble the rag. Summary of the invention
[0005] The embodiments of the present application provide a bracket assembly, a crawler-type cleaning assembly and a cleaning device, which are used to solve the problem in the above-mentioned related art that the crawler-type rag assembly is difficult to disassemble and assemble the rag due to the tension between the rag bracket and the rag.
[0006] In order to achieve the above objectives, the embodiments of the present application provide the following technical solutions:
[0007] A first aspect of an embodiment of the present application provides a bracket assembly, comprising:
[0008] A first bracket extending along a first direction;
[0009] The second bracket extends along the first direction, the second bracket and the first bracket are arranged side by side in the second direction, the second bracket is rotatably connected to the first bracket, the rotation axis of the first bracket and the second bracket is parallel to the first direction, and the second direction is perpendicular to the first direction; wherein,
[0010] The bracket assembly includes a flattened state and a folded state. When the bracket assembly is in the flattened state, the first bracket and the second bracket are located in the same plane. When the bracket assembly is folded from the flattened state to the folded state, the distance between the two ends of the first bracket and the second bracket that are away from each other is reduced.
[0011] In the stent assembly in the embodiments of the present application, by rotatably connecting the first stent and the second stent, a hinge connection structure can be formed between the first stent and the second stent, so that the distance between the two ends of the first stent and the second stent facing away from each other can be changed by folding or flattening the stent assembly. For example, when it is necessary to remove the rag on the crawler cleaning assembly, the stent assembly can be adjusted to a folded state, so that the distance between the two ends of the first stent and the second stent facing away from each other becomes smaller, so that the rag on the crawler cleaning assembly becomes loose, and then it is convenient to pull the rag out of the stent assembly. Similarly, when it is necessary to install the rag on the stent assembly, the stent assembly can be adjusted to a folded state first, the rag can be sleeved on the stent assembly, and then the stent assembly can be adjusted to a flattened state to support the rag to reach a tensioned state for cleaning operations.
[0012] By rotatably connecting the second stent to the first stent, the assembly difficulty between the first stent and the second stent can be reduced, and the assembly efficiency can be improved.
[0013] In a possible implementation, the stent assembly further includes at least one connecting shaft; wherein,
[0014] The connecting shaft extends along a first direction, the connecting shaft is arranged between the first stent and the second stent, and the first stent and the second stent are rotationally connected through the connecting shaft;
[0015] When the number of connecting shafts is multiple, the multiple connecting shafts are arranged in sequence along the first direction.
[0016] By providing the connecting shaft, the first stent and the second stent can rotate relative to each other. The connecting shaft can provide a stable rotation fulcrum and improve the connection stability between the first stent and the second stent. By using the connecting shaft, the design of the stent assembly can be more simplified, reducing the need for additional connecting parts or complex structures. This can reduce manufacturing costs and assembly complexity.
[0017] In a possible implementation, the first stent includes a first limiting portion, and the second stent includes a second limiting portion matching the first limiting portion; wherein,
[0018] When the stent assembly is opened from the folded state to the flattened state, the first limiting portion abuts against the second limiting portion to limit the reverse folding of the first stent and the second stent;
[0019] When the stent assembly is folded from the flattened state to the folded state, the first limiting portion abuts against the second limiting portion to limit the continuous folding of the first stent and the second stent.
[0020] By setting the first limiting part and the second limiting part, it is possible to prevent the first bracket and the second bracket from exceeding a predetermined angle during the folding process, avoiding mechanical damage caused by excessive folding. When the bracket assembly is unfolded to the flattened state, the abutment of the first limiting part and the second limiting part ensures the stability of the bracket assembly. By restricting reverse folding, the bracket assembly can remain stable during use, providing reliable support, thereby improving the overall use safety. The presence of the first limiting part and the second limiting part allows users not to overly concern about the folding angle when operating the bracket assembly, simplifies the usage process, and enhances the user experience. By preventing excessive folding and unnecessary stress, the first limiting part and the second limiting part can reduce the wear and fatigue of the bracket assembly, thereby extending its service life.
[0021] In a possible implementation manner, the first limiting part includes an adjacent first limiting surface and a second limiting surface, and the first limiting surface and the second limiting surface are arranged at an included angle;
[0022] The second limiting part includes an adjacent third limiting surface and a fourth limiting surface, and the third limiting surface and the fourth limiting surface are arranged at an included 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 limit the reverse folding of the first bracket and the second bracket;
[0024] When the bracket assembly is folded from the flattened state to the folded state, the second limiting surface abuts against the fourth limiting surface to limit the continuous folding of the first bracket and the second bracket.
[0025] By setting both the first limiting part and the second limiting part to have two adjacent limiting surfaces (the first and second limiting surfaces, and the third and fourth limiting surfaces), two-way limiting can be provided in different operating states. The bracket assembly can be effectively angle-limited during both the unfolding and folding processes, preventing excessive movement, preventing accidental excessive folding or unfolding, thereby reducing equipment damage and enhancing the overall use safety. In the flattened state, the abutment of the first limiting surface and the third limiting surface provides stable support and prevents reverse folding. In the folded state, the abutment of the second limiting surface and the fourth limiting surface prevents continuous folding, ensuring that the bracket assembly remains stable in both states. By dispersing stress through the contact between the limiting surfaces, the wear and stress concentration at a single contact point can be reduced. This can extend the service life of the bracket assembly and improve its durability.
[0026] In a possible implementation manner, 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] With such an arrangement, the first limiting portion and the second limiting portion can be reasonably arranged between the first bracket and the second bracket, reducing the external protruding portion, making the design more compact and beautiful. The first limiting portion and the second limiting portion are respectively located on the side where the first bracket and the second bracket are close to each other. This arrangement can provide better mechanical support when the bracket assembly is unfolded or folded, and enhance the strength and stability of the overall structure. This design can simplify the structure of the first bracket and the second bracket, reducing additional connectors or complex assembly steps.
[0028] In a possible implementation, when the bracket assembly is in the folded state, the angle between the first bracket and the second bracket is between 45° and 160°.
[0029] By setting the angle range to 45°-160°, a wide range of use angles can be provided for the bracket assembly to meet different application requirements. Users can adjust the angle of the bracket according to specific needs to obtain the best use experience. In addition, when the angle between the first bracket and the second bracket is 45°-160°, the distance between the ends of the first bracket and the second bracket that are away from each other is reduced, which can loosen the rag on the bracket, thereby facilitating the removal of the rag on the bracket assembly, and of course, it is also convenient to install a clean rag on the bracket assembly.
[0030] In a possible implementation, when the bracket assembly is in the folded state, the angle between the first bracket and the second bracket is between 50° and 80°.
[0031] In a possible implementation, when the bracket assembly is in the folded state, the angle between the first bracket and the second bracket is 60° or 70°.
[0032] In a possible implementation, one of the first bracket and the second bracket is provided with a first locking portion, and the other of the first bracket and the second bracket is provided with a second locking portion that cooperates with the first locking portion;
[0033] The first locking portion is used to be locked and connected with the second locking portion when the bracket assembly is in a flattened state.
[0034] By providing the first locking portion and the second locking portion, it is possible to ensure that the bracket assembly remains stable in the flattened state and will not be accidentally folded or moved due to external force or vibration, thereby improving the stability of the working state. In addition, it is also possible to enable the user to easily fix the bracket assembly in the flattened state without the need for additional tools or complicated operating steps, thereby improving the convenience of operation.
[0035] In a possible implementation, one of the first locking portion and the second locking portion is a boss structure, and the other of the first locking portion and the second locking portion is a groove structure;
[0036] When the bracket assembly is in the flattened state, the boss structure is engaged with the groove structure;
[0037] When the bracket assembly is folded from the flattened state to the folded state, the boss structure is disengaged from the groove structure.
[0038] By setting it in this way, the structures of the first locking portion and the second locking portion can be simplified, thereby simplifying the structure of the bracket assembly and reducing costs.
[0039] In a possible implementation, the bracket assembly includes a driving rotating shaft and a driven rotating shaft; among them,
[0040] The driving rotating shaft is sleeved on the side of the first bracket facing away from the second bracket, and the driving rotating shaft is rotatably connected to the first bracket;
[0041] The driven rotating shaft is sleeved on the side of the second bracket facing away from the first bracket, and the driven rotating shaft is rotatably connected to the second bracket.
[0042] By setting it in this way, when the bracket assembly is applied to the crawler cleaning assembly, through the coordinated work of the driving rotating shaft and the driven rotating shaft, the power can be effectively transmitted to the rag sleeved on the outside of the bracket assembly, ensuring that the rag can move smoothly and efficiently, and improving the cleaning efficiency.
[0043] In a possible implementation, the driving rotating shaft includes a first support section and a first constricted section that are alternately arranged along the axial direction, and the diameter of the first constricted section is smaller than that of the first support section;
[0044] At least one first limiting boss is provided on the first bracket, the first limiting boss is arranged opposite to the first constricted section, and a part of the structure of the first limiting boss extends to the inside of the outer contour of the first support section.
[0045] By setting it in this way, through the cooperation of the first limiting boss and the first constricted section, the driving rotating shaft can be prevented from shaking in the radial direction, and the stability of the bracket assembly can be improved.
[0046] In a possible implementation, the first support section is made of soft rubber material, and the first constricted section is made of non-soft rubber material.
[0047] By setting the first support section as a soft rubber material, when the rag is sleeved on the bracket assembly, the friction between the driving rotating shaft and the rag can be increased, so that the driving rotating shaft can drive the rag to move. By setting the first constricted section as a non-soft rubber material, it can prevent noise from being generated due to the contact between the first limiting boss and the soft rubber material.
[0048] In a possible implementation, the driven rotating shaft includes a second support section and a second constricted section that are alternately arranged along the axial direction, and the diameter of the second constricted 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 arranged opposite to the second retracted section, and a part of the structure of the second limiting boss extends to the inner side of the outer contour of the second supporting section;
[0050] Both the second supporting section and the second retracted section are made of non-soft rubber material.
[0051] With such an arrangement, it is possible to prevent the driven rotating shaft from shaking in the radial direction and improve the stability of the bracket assembly. By making both the second supporting section and the second retracted section of non-soft rubber material, the structure of the driven rotating shaft can be simplified, thereby reducing costs, and the noise between the second limiting boss and the driven rotating shaft can also be reduced.
[0052] In the second aspect of the embodiments of the present application, a crawler-type cleaning assembly is provided, including a cleaning cloth and the bracket assembly according to any one of the above first aspects; wherein,
[0053] The cleaning cloth is sleeved on the outer side of the bracket assembly, and the cleaning cloth is detachably connected to the bracket assembly;
[0054] When the bracket assembly is in a flattened state, there is a tension force between the cleaning cloth and the bracket assembly.
[0055] By providing the bracket assembly of the first aspect, when it is necessary to disassemble the cleaning cloth, the bracket assembly can be folded so that the two ends of the bracket assembly facing away from each other are close to each other, and then the cleaning cloth located on the bracket assembly is in a relaxed state, so as to disassemble the cleaning cloth assembly from the bracket assembly.
[0056] In the third aspect of the embodiments of the present application, a cleaning device is provided, including a device body and the crawler-type cleaning assembly of the second aspect. BRIEF DESCRIPTION OF THE DRAWINGS

[0078] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0079] With the development of automatic cleaning equipment, sweeping robots with mopping functions are widely welcomed. Generally, the mopping modules of sweeping robots can be roughly divided into: disc-type rag assembly, drum-type rag assembly and crawler-type rag assembly according to different product forms. Among them, the crawler-type rag assembly has the advantages of large mopping area, strong ground pressure and close mopping effect compared with disc-type and drum-type rag assemblies.
[0080] The crawler rag assembly usually includes a rag bracket and a rag. The rag is arranged on the outside of the rag bracket, and the crawler rag assembly is installed on the sweeping robot through the rag bracket. There is a certain tension between the rag bracket and the rag on the crawler rag assembly in the related art. Under the action of the tension, the rag bracket drives the rag to move to achieve the mopping function. After using it for a period of time, the user needs to remove the rag from the rag bracket for cleaning or replacement.
[0081] However, due to the tension between the rag bracket and the rag, it is difficult to disassemble and assemble the rag. In order to solve the above technical problems, the embodiment of the present application provides a bracket assembly, which has a simple structure and can be folded to reduce the distance between the two ends of the bracket assembly that are away from each other, so that the rag on the bracket assembly becomes loose, and then the rag can be easily pulled out from the bracket assembly.
[0082] The bracket assembly, crawler cleaning assembly and cleaning equipment provided in the embodiments of the present application are described in detail below in conjunction with the accompanying drawings.
[0083] Figure 1 A schematic structural diagram of a bracket assembly provided in an embodiment of the present application. Figure 2 A structural schematic diagram of a bracket assembly in a folded state provided in an embodiment of the present application.
[0084] It should be noted that, for the convenience of description, in the embodiment of the present application, the first direction is taken as the x direction, the second direction is taken as the y direction, and the third direction is taken as the z direction, and the first direction, the second direction and the third direction are perpendicular to each other. Among them, the third direction can be taken as the thickness direction of the bracket assembly.
[0085] The present application embodiment provides a bracket assembly 100, such as Figure 1As shown, the bracket assembly 100 may include a first bracket 10 and a second bracket 20. Among them, the first bracket 10 extends along a first direction (x direction), and the second bracket 20 also extends along the first direction (x direction). The second bracket 20 is arranged side by side with the first bracket 10 in a second direction (y direction). The second bracket 20 is rotatably connected to the first bracket 10. The rotation axes of the first bracket 10 and the second bracket 20 are parallel to the first direction (x direction), and the second direction (y direction) is perpendicular to the first direction (x direction).
[0086] As Figure 1 and Figure 2 As shown, the bracket assembly 100 may include a flattened state and a folded state. When the bracket assembly 100 is in the flattened state, the first bracket 10 and the second bracket 20 are located in the same plane. When the bracket assembly 100 is folded from the flattened state to the folded state, the distance between the two ends of the first bracket 10 and the second bracket 20 that face away from each other decreases.
[0087] Exemplarily, when the second direction (y direction) is the direction of forward or backward movement of the cleaning device 400 when the bracket assembly 100 is applied to the crawler cleaning assembly 200, that is to say, the first bracket 10 and the second bracket 20 can be arranged front and back along the moving direction of the cleaning device 400.
[0088] It should be noted that the statement "the rotation axes of the first bracket 10 and the second bracket 20 are parallel to the first direction (x direction)" means parallel within a certain error range. That is to say, the rotation axes of the first bracket 10 and the second bracket 20 are generally parallel to the first direction (x direction). For example, when the angle between the rotation axes of the first bracket 10 and the second bracket 20 and the first direction (x direction) is within 5°, it can be considered parallel.
[0089] Similarly, the statement "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 generally 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°. Exemplarily, when the angle between the first direction (x direction) and the second direction (y direction) is between 85° and 90°, and between 90° and 95°, it can be considered that the first direction (x direction) and the second direction (y direction) are 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°, 95°, the first direction (x direction) is perpendicular to the second direction (y direction).
[0090] It should be noted that the statement "the first bracket 10 and the second bracket 20 are located in the same plane" means that in the ideal state where the thickness of the first bracket 10 and the second bracket 20 is basically zero, the first bracket 10 and the second bracket 20 are basically located in the same plane (see Figure 1 shown). At this time, the distance between the mutually facing ends of the first bracket 10 and the second bracket 20 is in the maximum state. And when the cleaning cloth 300 is sleeved on the bracket assembly 100, the surface of the cleaning cloth 300 is approximately presented as a planar structure, and there is no protrusion or depression at the connection position of the first bracket 10 and the second bracket 20.
[0091] In the bracket assembly 100 of the embodiment of the present application, by rotatably connecting the first bracket 10 and the second bracket 20, a hinge connection structure can be formed between the first bracket 10 and the second bracket 20, so that the distance between the mutually facing ends of the first bracket 10 and the second bracket 20 can be changed by folding or flattening the bracket assembly 100. For example, when it is necessary to disassemble the cleaning cloth 300 on the crawler-type cleaning assembly 200 (see Figure 7 shown), the bracket assembly 100 can be adjusted to a folded state, so that the distance between the mutually facing ends of the first bracket 10 and the second bracket 20 becomes smaller, so that the cleaning cloth 300 on the crawler-type cleaning assembly 200 becomes loose, and then it is convenient to pull out the cleaning cloth 300 from the bracket assembly 100. Similarly, when it is necessary to install the cleaning cloth 300 on the bracket assembly 100, the bracket assembly 100 can be first adjusted to a folded state, the cleaning cloth 300 can be sleeved on the bracket assembly 100, and then the bracket assembly 100 can be adjusted to a flattened state to support the cleaning cloth 300 to reach a tensioned state for cleaning operations.
[0092] By rotatably connecting the second bracket 20 with the first bracket 10, the assembly difficulty between the first bracket 10 and the second bracket 20 can be reduced, and the assembly efficiency can be improved.
[0093] As Figure 3 shown, the bracket assembly 100 may further include at least one connecting shaft 30. Wherein, the connecting shaft 30 extends along the first direction (x direction), the connecting shaft 30 is arranged between the first bracket 10 and the second bracket 20, and the first bracket 10 and the second bracket 20 are rotationally connected through the connecting shaft 30. When the number of connecting shafts 30 is multiple, the multiple connecting shafts 30 are arranged in sequence along the first direction (x direction). Exemplarily, the number of connecting shafts 30 may be one, two, three or more, and in the embodiment of the present application, 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 can provide a stable rotation fulcrum, improving the connection stability between the first bracket 10 and the second bracket 20. By using the connecting shaft 30, the design of the bracket assembly 100 can be simplified, reducing the need for additional connecting components or complex structures. This can lower the manufacturing cost and assembly complexity.
[0095] It should be noted that when the number of connecting shafts 30 is multiple, the dimensions of the multiple connecting shafts 30 in the first direction (x-direction) can be the same or different, as long as the connection relationship between the first bracket 10 and the second bracket 20 can be satisfied.
[0096] As Figure 3 shown, both the first bracket 10 and the second bracket 20 can include connection holes for the connecting shaft 30 to pass through. The connecting shaft 30 rotatably connects the first bracket 10 and the second bracket 20 by passing through the connection holes of the first bracket 10 and the second bracket 20.
[0097] Continuing to refer to Figure 2 and Figure 3 shown, the first bracket 10 can include a first limiting portion 11, and the second bracket 20 includes a second limiting portion 21 that matches the first limiting portion 11. Among them, when the bracket assembly 100 is opened from the folded state to the flattened state, the first limiting portion 11 abuts against the second limiting portion 21 to limit the reverse folding of the first bracket 10 and the second bracket 20. When the bracket assembly 100 is folded from the flattened state to the folded state, the first limiting portion 11 abuts against the second limiting portion 21 to limit the further folding of the first bracket 10 and the second bracket 20.
[0098] It should be noted that "reverse folding" means folding in the opposite direction after folding from the folded state to the flattened state along the direction from the folded state to the flattened state. For example, if the folded state is an inward fold, then reverse folding will cause the bracket assembly 100 to present an outward fold state. In Figure 2 reverse folding is represented as direction c, and forward folding is represented as s.
[0099] By providing the first limiting portion 11 and the second limiting portion 21, the first bracket 10 and the second bracket 20 can be prevented from exceeding a predetermined angle during the folding process, thereby avoiding mechanical damage caused by excessive folding. When the bracket assembly 100 is unfolded to a flattened state, the abutment of the first limiting portion 11 and the second limiting portion 21 ensures the stability of the bracket assembly 100. By limiting the reverse folding, the bracket assembly 100 can remain stable during use and provide reliable support, thereby improving the overall safety of use. The presence of the first limiting portion 11 and the second limiting portion 21 eliminates the need for the user to pay too much attention to the folding angle when operating the bracket assembly 100, simplifies the use process, and improves the user experience. By preventing excessive folding and unnecessary stress, the first limiting portion 11 and the second limiting portion 21 can reduce wear and fatigue on the bracket assembly 100, thereby extending its service life.
[0100] In a possible implementation, in the second direction (y direction), the first limiting portion 11 is located on the side of the first bracket 10 facing the second bracket 20, and the second limiting portion 21 is located on the side of the second bracket 20 facing the first bracket 10. In other words, the first limiting portion 11 and the second limiting portion 21 are respectively located on the side where the first bracket 10 and the second bracket 20 are close to each other.
[0101] It should be noted that in the embodiments of the present application, "towards" refers to orientation in a broad sense, and is not limited to a frontal relative arrangement; and "deviating from" refers to deviation in a broad sense, and is not limited to a back-to-back parallel relative arrangement.
[0102] In this way, the first limiting portion 11 and the second limiting portion 21 can be reasonably arranged on the first bracket 10 and the second bracket 20, reducing the external protruding parts, making the design more compact and beautiful. The first limiting portion 11 and the second limiting portion 21 are respectively located on the side where the first bracket 10 and the second bracket 20 are close to each other. This arrangement can provide better mechanical support when the bracket assembly 100 is unfolded or folded, and enhance the strength and stability of the overall structure. This design can simplify the structure of the first bracket 10 and the second bracket 20, reducing additional connectors or complicated assembly steps.
[0103] Continue to see Figure 2 and Figure 3 As shown, one of the first bracket 10 and the second bracket 20 is provided with a first locking portion 12, and the other of the first bracket 10 and the second bracket 20 is provided with a second locking portion 24 that cooperates with the first locking portion 12. The first locking portion 12 is used to be locked and connected with the second locking portion 24 when the bracket assembly 100 is in a flattened state.
[0104] Exemplarily, the locking connection between the first locking portion 12 and the second locking portion 24 can specifically be a snap connection implemented through a snap portion, or a locking connection implemented through frictional force. The locking relationship can be directly destroyed by an external force and the locking relationship can also be achieved by an external force. In the embodiments of the present application, no further limitation is imposed on the locking manner between the first locking portion 12 and the second locking portion 24.
[0105] By providing the first locking portion 12 and the second locking portion 24, it can be ensured that the bracket assembly 100 remains stable in the flattened state and will not be accidentally folded or moved due to external forces or vibrations, thereby improving the stability in the working state. Additionally, it can also enable the user to easily fix the bracket assembly 100 in the flattened state without the need for additional tools or complex operating steps, improving the operation convenience.
[0106] In a 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 the flattened state, the boss structure is snap-connected to the groove structure. When the bracket assembly 100 is folded from the flattened state to the folded state, the boss structure is disengaged from the groove structure. Among them, the boss structure can be frictionally locked to the groove structure. When the boss structure and the groove structure are locked, the boss structure is located inside the groove structure and is in interference fit with the groove structure.
[0107] With such a setting, the structures of the first locking portion 12 and the second locking portion 24 can be simplified, and further the structure of the bracket assembly 100 can be simplified, thereby reducing the cost.
[0108] Continue to refer to Figure 3 As shown, the bracket assembly 100 can include a driving rotation shaft 13 and a driven rotation shaft 22. Among them, the driving rotation shaft 13 is sleeved on the side of the first bracket 10 away from the second bracket 20, and the driving rotation shaft 13 is rotatably connected to the first bracket 10. The driven rotation shaft 22 is sleeved on the side of the second bracket 20 away from the first bracket 10, and the driven rotation shaft 22 is rotatably connected to the second bracket 20.
[0109] It should be noted that the axial directions of the driving rotation shaft 13, the driven rotation shaft 22, and the connecting shaft 30 are pairwise parallel to each other.
[0110] With such a setting, when the bracket assembly 100 is applied to the crawler cleaning assembly 200 (refer to Figure 8 as shown), through the coordinated operation of the driving rotation shaft 13 and the driven rotation shaft 22, the power can be effectively transmitted to the rag 300 sleeved outside the bracket assembly 100, ensuring that the rag 300 can move smoothly and efficiently, and improving the cleaning efficiency.
[0111] Continue to refer to Figure 3 As shown, the driving rotating shaft 13 may include a first supporting section 131 and a first retracted section 132 alternately arranged along the axial direction (x direction). The diameter of the first retracted section 132 is smaller than that of the first supporting section 131. At least one first limiting boss 14 is provided on the first bracket 10. The first limiting boss 14 is arranged opposite to the first retracted section 132, and a part of the structure of the first limiting boss 14 extends to the inner side of the outer contour of the first supporting section 131 (refer to Figure 1 as shown).
[0112] The driven rotating shaft 22 may include a second supporting section 221 and a second retracted section 222 alternately arranged along the axial direction (x direction). The diameter of the second retracted section 222 is smaller than that of the second supporting section 221. At least one second limiting boss 23 is provided on the second bracket 20. The second limiting boss 23 is arranged opposite to the second retracted section 222, and a part of the structure of the second limiting boss 23 extends to the inner side of the outer contour of the second supporting section 221.
[0113] It should be noted that when the cleaning cloth 300 is sleeved on the bracket assembly 100, the first supporting section 131 and the second supporting end are used to contact and connect with the cleaning cloth 300. The driving rotating shaft 13 can apply a certain driving force to the cleaning cloth 300 to drive the cleaning cloth 300 to move relative to the bracket assembly 100.
[0114] By setting the driving rotating shaft 13 to include the first supporting section 131 and the first retracted section 132, and setting the driven rotating shaft 22 to include the second supporting section 221 and the second retracted section 222, and providing the first limiting boss 14 on the first bracket 10 and the second limiting boss 23 on the second bracket 20, the cooperation between the first limiting boss 14 and the first retracted section 132 can prevent the driving rotating shaft 13 from shaking in the radial direction, and the cooperation between the second limiting boss 23 and the second retracted section 222 can prevent the driven rotating shaft 22 from shaking in the radial direction, thereby improving the stability of the bracket assembly 100.
[0115] In a possible implementation manner, the first supporting section 131 is made of soft rubber material, and the first retracted section 132 is made of non-soft rubber material. Both the second supporting section 221 and the second retracted section 222 are made of non-soft rubber material.
[0116] Exemplarily, the soft rubber material can be silicone, thermoplastic elastomer, polyurethane, neoprene, etc. The non-soft rubber material can be plastic or hard plastic, etc. In the embodiments of the present application, the materials of the driving rotating shaft 13 and the driven rotating shaft 22 are not further limited, and can be specifically set according to actual needs.
[0117] By setting the first support section 131 to be made of soft rubber material, when the cleaning cloth 300 is sleeved on the bracket assembly 100, the frictional force between the driving rotation shaft 13 and the cleaning cloth 300 can be increased, so that the driving rotation shaft 13 can drive the cleaning cloth 300 to move. By setting the first retracted section 132 to be made of non-soft rubber material, it is possible to prevent noise from being generated due to the contact between the first limiting boss 14 and the soft rubber material. By making both the second support section 221 and the second retracted section 222 made of non-soft rubber material, the structure of the driven rotation shaft 22 can be simplified, thereby reducing costs, and it can also reduce the noise between the second limiting boss 23 and the driven rotation shaft 22.
[0118] The first limiting portion 11 and the second limiting portion 21 will be described in detail below with reference to the accompanying drawings.
[0119] As Figure 4 shown, the first limiting portion 11 may include an adjacent first limiting surface 111 and a second limiting surface 112, and the first limiting surface 111 and the second limiting surface 112 are arranged at an angle. As Figure 5 shown, the second limiting portion 21 may include an adjacent third limiting surface 211 and a fourth limiting surface 212, 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 shown) to limit the reverse folding of the first bracket 10 and the second bracket 20. When the bracket assembly 100 is folded from the flattened state to the folded state, the second limiting surface 112 abuts against the fourth limiting surface 212 (see Figure 7 shown) to limit the further folding of the first bracket 10 and the second bracket 20.
[0120] It should be noted that in the embodiments of the present application, the angle between the first limiting surface 111 and the second limiting surface 112 is not limited. For example, the angle between the first limiting surface 111 and the second limiting surface 112 can be between 100° and 160°. The angle between the third limiting surface 211 and the fourth limiting surface 212 of the bracket can be set to be close to 90°, and specifically can be set according to the angle between the first bracket 10 and the second bracket 20 in the folded state. In the embodiments of the present application, the angle between the first limiting surface 111 and the second limiting surface 112, and the angle between the third limiting surface 211 and the fourth limiting surface 212 are not further limited.
[0121] By setting the first limiting portion 11 and the second limiting portion 21 to have two adjacent limiting surfaces (the first limiting portion 11 and the second limiting surface 112, and the third limiting surface 211 and the fourth limiting surface 212), bidirectional limiting can be provided in different operating states. The bracket assembly 100 can be effectively angle-restricted during the unfolding and folding process to prevent excessive movement and accidental excessive folding or unfolding, thereby reducing equipment damage and improving overall safety of use. In the flattened state, the abutment between the first limiting surface 111 and the third limiting surface 211 provides stable support to prevent reverse folding. In the folded state, the abutment 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. The contact between the limiting surfaces disperses stress, which can reduce wear and stress concentration at a single contact point. This can extend the service life of the bracket assembly 100 and improve its durability.
[0122] For explanation, the distance from the axis of the driving rotating shaft 13 to the axis of the connecting shaft 30 is fixed at L1, and the distance from the axis of the driven rotating shaft 22 to the axis of the connecting shaft 30 is fixed at L2. The distance from the axis of the driving rotating shaft 13 to the axis of the driven rotating 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 bracket assembly 100 is in the folded state, the connecting lines between the axis of the active rotating shaft 13, the axis of the connecting shaft 30, and the axis of the driven rotating shaft 22 form a triangle, wherein L3 is smaller than the sum of L2 and L1.
[0124] In this way, when the same rag 300 is put on the bracket assembly 100, the rag 300 is fluffy when the bracket assembly 100 is in a folded state than in a flat state, which means that in the folded state, there is almost no tension between the rag 300 and the bracket assembly 100, so it is easy to install and remove the bracket assembly 100 and the rag 300.
[0125] For example, Figure 7 As shown, when the bracket assembly 100 is in the folded state, the angle between the first bracket 10 and the second bracket 20 can be the angle between the line between the connecting shaft 30 and the active rotating shaft 13 and the line between the connecting shaft 30 and the driven rotating shaft 22, which is represented by a 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 requirements. Users can adjust the angle of the bracket according to specific needs to obtain the best usage experience. Additionally, when the included angle between the first bracket 10 and the second bracket 20 is within 45° - 160°, the distance between the mutually facing ends of the first bracket 10 and the second bracket 20 decreases, which can cause the cleaning cloth 300 on the bracket to become slack, thereby facilitating the removal of the cleaning cloth 300 from the bracket assembly 100. Of course, it also facilitates the installation of a clean cleaning cloth 300 on the bracket assembly 100.
[0127] In some embodiments, when the bracket assembly 100 is in the folded state, the included angle a between the first bracket 10 and the second bracket 20 can be between 50° and 80°.
[0128] In some other embodiments, when the bracket assembly 100 is in the folded state, the included angle a between the first bracket 10 and the second bracket 20 can be 60° or 70°.
[0129] In some embodiments, when the bracket assembly 100 is in the folded state, the included angle a 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 the embodiments of the present application, the specific value of the included angle a between the first bracket 10 and the second bracket 20 is not further limited and can be specifically set according to specific requirements.
[0130] The embodiments of the present application also provide a crawler - type cleaning assembly 200, as Figure 8 shown. The crawler - type cleaning assembly 200 can include a cleaning cloth 300 and a bracket assembly 100 as described in any one of the above - mentioned first aspects. Among them, the cleaning cloth 300 is sleeved outside the bracket assembly 100, and the cleaning cloth 300 is detachably connected to the bracket assembly 100. When the bracket assembly 100 is in the flattened state, there is a tension force between the cleaning cloth 300 and the bracket assembly 100.
[0131] By providing the bracket assembly 100 of the first aspect, when it is necessary to remove the cleaning cloth 300, the bracket assembly 100 can be folded so that the mutually facing ends of the bracket assembly 100 approach each other, thereby causing the cleaning cloth 300 on the bracket assembly 100 to be in a slack state, so as to remove the cleaning cloth assembly from the bracket assembly 100.
[0132] The embodiments of the present application also provide a cleaning device 400, as Figure 9As shown, the cleaning device 400 may include a device body 500 and a crawler-type cleaning assembly 200. The cleaning device 400 can mop the floor through the crawler-type cleaning assembly 200. Among them, the cleaning device 400 has all the advantages of the crawler-type cleaning assembly 200.
