DETAILED DESCRIPTION

[0032] The following is a further detailed description of the implementation of the present application in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present application but cannot be used to limit the scope of the present application.

[0033] In the description of the embodiments of the present application, it should be noted that the terms "upper", "lower", "top", "bottom", "inside", "outside", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the embodiments of the present application. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0034] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0035] In the embodiments of the present application, unless otherwise clearly specified and limited, a first feature being “above” or “below” a second feature may mean that the first feature is in direct contact with the second feature, or the first feature and the second feature are in indirect contact through an intermediate medium. Moreover, a first feature being “above”, “above”, and “above” a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being “below”, “below”, and “below” a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0036] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the embodiment of the present application. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example.

[0037] The present application embodiment provides a cleaning assembly 100, see Figure 2 and Figure 3 The cleaning assembly 100 includes a supporting device 10, a cleaning belt 20 and a stopper 30. The supporting device 10 includes a bracket 12 and two rollers 11, and the two rollers 11 are arranged in parallel and are rotatably disposed on the bracket 12 respectively.

[0038] The relationship between the outer diameters of the two rollers 11 is not limited, and the outer diameters of the two rollers 11 can be the same or different.

[0039] See also Figure 2 and Figure 4 The cleaning belt 20 is wound around the outer periphery of the supporting device 10 and contacts the two rollers 11 respectively, and is used to move relative to the supporting surface under the drive of at least one roller 11. The supporting surface is not limited and can be the ground or a wall.

[0040] It is understandable that the cleaning belt 20 is in a belt shape, and has a cleaning effect by wiping the support surface, and the bracket 12 supports the roller 11, and the two rollers 11 can tension the cleaning belt 20. The cleaning assembly 100 is placed on the support surface and contacts the support surface, and the cleaning belt 20 can move under the drive of at least one roller 11 to clean the support surface. In this process, there is a large contact area between the cleaning belt 20 and the support surface, which is conducive to improving the cleaning efficiency of the cleaning assembly 100.

[0041] The form of the cleaning belt 20 is not limited. For example, in one embodiment, the cleaning belt 20 includes a rubber matrix and a fabric layer coated on the outer surface of the rubber matrix. The rubber matrix has good elasticity and can bend and deform adaptively to keep the fabric layer in contact with the support surface. The fabric layer can be made of woven fabric or spun yarn.

[0042] The application scenarios of the cleaning component 100 are not limited. For example, please refer to Figure 1 The embodiment of the present application also provides a cleaning robot, which includes a main body 200 and a cleaning component 100 of any embodiment of the present application. The cleaning component 100 is arranged on the main body 200. The cleaning robot can automatically detect the surrounding environment through the sensors and control modules carried on the main body 200, plan its moving route on the ground, and realize active obstacle avoidance, turning and other actions. The main body 200 of the cleaning robot includes a motor (not shown in the figure), and the motor is connected to at least one of the two rollers 11 to drive the cleaning belt 20 to move. For example, in one embodiment, the motor and Figure 2 The roller 11 pointed by the arrow a is connected.

[0043] Exemplarily, the cleaning robot also includes a roller brush 300, which is arranged on the main body 200. Along the moving direction of the cleaning robot, the roller brush 300 is arranged in front of the cleaning component 100 for sweeping and collecting debris, garbage, etc. on the ground, while the cleaning component 100 is used to clean stains on the ground.

[0044] This specification takes the cleaning component 100 applied to a cleaning robot as an example for explanation. Of course, the cleaning component 100 can also be equipped on other cleaning equipment, such as a mopping machine, etc.

[0045] The cleaning assembly 100 includes at least two stoppers 30, that is, the number of the stoppers 30 can be two, three or more. At least one roller 11 is connected to the stoppers 30 at two opposite ends along the axial direction, and the cleaning belt 20 is located between the stoppers 30 at both ends of the roller 11 along the axial direction, and the roller 11 provides installation support for the stoppers 30.

[0046] In the radial direction of the roller 11, the stopper 30 protrudes from the outer peripheral surface of the roller 11 and does not exceed the outer peripheral surface of the cleaning belt 20. In this way, the stopper 30 plays an axial limiting role on the cleaning belt 20 and hardly interferes with the movement of the cleaning belt 20 relative to the supporting surface.

[0047] For example, in one embodiment, along the radial direction of the roller 11, the top side of the stopper 30 is substantially flush with the rubber matrix and lower than the fabric layer. Compared with the fabric layer, the rubber matrix has a more stable shape, and the stopper 30 can abut against the rubber matrix, thereby providing a better limit for the cleaning belt 20.

[0048] When the cleaning robot moves, in some cases, such as when turning, due to factors such as the turning radius, the two sides perpendicular to its moving direction are prone to displacement differences, which makes the cleaning belt 20 tend to move along the axial direction under the action of the ground friction, especially when the contact area with the ground is large, this tendency is more obvious, and the limiting members 30 on both sides of the cleaning belt 20 can limit the cleaning belt 20. In this way, when the cleaning robot moves, turns, etc., the cleaning belt 20 will not easily slip or fall out, which can improve the working stability of the cleaning assembly 100.

[0049] It should be noted that the axial directions mentioned in this specification are all along the axis direction of the roller 11 .

[0050] For some examples, see Figure 3 and Figure 4 , two rollers 11 are provided with limiting members 30 at opposite ends along the axis. It can be seen that at least four structures of the cleaning belt 20 can be affected by the limiting members 30, thereby further enhancing the limiting effect of the limiting members 30. And the one-to-one connection between the ends of the rollers 11 and the limiting members 30 is simple in structure and convenient for installation.

[0051] For some examples, see Figure 2 The stopper 30 is annular and surrounds the outer circumference of the roller 11. The annular stopper 30 can adapt to the outer edge shape of the roller 11, and try to avoid the stopper 30 from contacting the supporting surface, thereby reducing its influence on the movement of the cleaning belt 20.

[0052] For some examples, see Figure 5 The bracket 12 includes a support portion 12c, and the roller 11 includes a first shaft segment 111 and two second shaft segments 112. The two second shaft segments 112 are respectively arranged at two ends of the first shaft segment 111 along the axial direction. The outer diameter of the second shaft segment 112 is smaller than the outer diameter of the first shaft segment 111, and the second shaft segment 112 passes through the support portion 12c. In other words, the roller 11 is supported on the support portion 12c through the second shaft segment 112.

[0053] For example, in one embodiment, Figure 5 As shown, the stopper 30 is connected to the second shaft section 112 and is located on the side of the support portion 12c away from the first shaft section 111. In this way, the cleaning belt 20 can be made as wide as possible along the axial direction under the premise of installing and fixing the stopper 30, thereby improving its cleaning efficiency.

[0054] Illustratively, in another embodiment, the stopper 30 is connected to the first shaft segment 111 and is located on a side of the support portion 12 c close to the first shaft segment 111 , so that the roller 11 can be easily installed on the bracket 12 .

[0055] In some embodiments, the first shaft segment 111, the second shaft segment 112 and the stopper 30 are an integrated component, which has a simple and reliable structure and is easy to process. For example, the support portion 12c has a notch along the axial direction of the second shaft segment 112, and the notch can be elastically deformed to change its size. The user can squeeze the second roller 11 into the support portion 12c through the notch to complete the installation of the roller 11.

[0056] Of course, in some other embodiments, the first shaft segment 111 and the second shaft segment 112 may be an integrated component, and the limiting member 30 may be installed on the second roller 11 by means of adhesive connection or threaded connection.

[0057] The cleaning assembly 100 provided in the embodiment of the present application has a bracket 12 comprising a first bracket 121 and a second bracket 122 connected to each other, wherein one roller 11 is rotatably disposed on the first bracket 121 , and the other roller 11 is rotatably disposed on the second bracket 122 .

[0058] The first bracket 121 and the second bracket 122 can move relative to each other to switch between an unfolded state and a folded state. Figure 6 As shown, in the unfolded state, the two rollers 11 tension the cleaning belt 20; Figure 7 As shown, in the folded state, the distance between the two rollers 11 is smaller than the distance between the two rollers 11 in the unfolded state.

[0059] It is understandable that when the first bracket 121 and the second bracket 122 move relative to each other, the relative positions of the two rollers 11 change accordingly. When the cleaning belt 20 is tensioned, a belt transmission is formed between the two rollers 11 and the cleaning belt 20. When the cleaning belt 20 is loose, there is a sufficient gap between the cleaning belt 20 and the two rollers 11, so that the cleaning belt 20 has a certain margin of activity and can be easily disassembled so that the user can replace, repair, etc. the cleaning belt 20. When the cleaning belt 20 needs to be installed on the supporting device 10, the bracket 12 is in a folded state, the cleaning belt 20 is wound on the supporting device 10, and then the bracket 12 is switched to the unfolded state, the cleaning belt 20 is tensioned, and the installation of the cleaning belt 20 is completed.

[0060] In addition, the foldable support device 10 also allows the user to install the cleaning belt 20 without removing the limit member 30. The limit member 30 can be driven to move by the folding bracket 12 so that the cleaning belt 20 can be bypassed by the limit member 30 and installed on the roller 11. In this way, the use of the cleaning assembly 100 becomes simpler and easier for the user to use.

[0061] In some embodiments, the distance between the axes of the two rollers 11 is the largest in the unfolded state and the smallest in the folded state. It should be noted that when the distance between the two rollers 11 is the smallest, it is in the folded state; when the distance between the two rollers 11 is the largest, it is in the unfolded state.

[0062] In this embodiment, the first bracket 121 and the second bracket 122 move relative to each other, and the distance between the axis of the first roller 11 and the axis of the second roller 11 changes accordingly. When the distance is maximum, the tension of the cleaning belt 20 is large and the transmission efficiency is high; when the distance is minimum, the cleaning belt 20 has a large movable margin and is easier and more convenient to disassemble.

[0063] For some examples, see Figure 6 and Figure 7 One of the first bracket 121 and the second bracket 122 has at least one stopping protrusion 12b, and the other has at least one positioning recess 12a; the stopping protrusion 12b has a limiting effect when matched with the positioning recess 12a, so that the first bracket 121 and the second bracket 122 are relatively fixed.

[0064] In the unfolded state, the stop protrusion 12b cooperates with one positioning recess 12a to keep the bracket 12 in the unfolded state. Further, the number of the positioning recesses 12a is at least two, and in the folded state, the stop protrusion 12b cooperates with another positioning recess 12a to keep the bracket 12 in the folded state, so that the user can disassemble it more conveniently and labor-savingly.

[0065] In addition, in this embodiment, when the bracket 12 switches between the unfolded state and the folded state, the user can experience the gear position sense, and through the perceptible information such as the vibration or sound when the stop protrusion 12b cooperates with the positioning recess 12a, the user can intuitively perceive the current relative position of the first bracket 121 and the second bracket 122. For example, when a crisp "click" sound is heard, the user can judge that the bracket 12 has completed the switch between the two states.

[0066] In some embodiments, the first bracket 121 is rotatably connected to the second bracket 122 , and the two rotate relative to each other around a rotation axis; the rotation axis and the axes of the two rollers 11 are parallel to each other.

[0067] That is, the rotation axis, the axis bracket 12 of the two rollers 11 form an angle. When the first bracket 121 and the second bracket 122 rotate, the size of the angle changes, and the distance between the axis of the first roller 11 and the axis of the second roller 11 also changes accordingly.

[0068] This embodiment achieves the change of the distance between the axis and the axis by rotation, which is convenient for the user to hold the cleaning assembly 100 and switch the state of the bracket 12. For example, the user can use the axis as a fulcrum to apply force to the first bracket 121 or the second bracket 122, and use the force-saving effect of the lever to easily make the first bracket 121 and the second bracket 122 rotate relative to each other.

[0069] Of course, the supporting device 10 is not limited to being folded by rotation, but can also be folded by pushing, pulling and translating to change the distance between the first bracket 121 and the second bracket 122 to switch between the folded state and the unfolded state.

[0070] The various embodiments / implementations provided in this application can be combined with each other without causing any contradiction.

[0071] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
