In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example.

[0040] The present application embodiment provides a cleaning assembly 100, see Figure 3 The cleaning assembly 100 includes a supporting device 10 and a cleaning belt 20. The supporting device 10 includes two rollers 11 and a bracket 12. The two rollers 11 are arranged in parallel and are rotatably disposed on the bracket 12. The cleaning belt 20 is wound around the outer circumference 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.

[0041] The cleaning belt 20 is in the shape of a belt, and has a cleaning effect by wiping the support surface. It can be understood that 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 the cleaning belt 20 can move under the drive of at least one roller 11 to wipe the support surface.

[0042] 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 cloth 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 cloth layer in contact with the support surface.

[0043] The cleaning component 100 may be used in any application scenario. Figure 1 The embodiment of the present application also provides a cleaning robot, which includes a main body and a cleaning component 100 of any embodiment of the present application, and the cleaning component 100 is arranged on the main body. The cleaning robot can automatically detect the surrounding environment through the sensor and control module carried on the main body, plan the moving route on the support surface, and realize active obstacle avoidance, turning and other actions. The main body includes a motor, and the motor is connected to at least one of the two rollers 11 to drive the cleaning belt 20 to move.

[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] In the cleaning assembly 100 of the embodiment of the present application, at least one annular recessed area 11a is formed on the outer circumference of each of the two rollers 11, and the inner circumference of the cleaning belt 20 has at least one convex ring portion 20a, which is disposed in the annular recessed area 11a.

[0046] It should be noted that the annular recessed area 11 a is arranged around the outer circumference of the roller 11 , and during the movement of the cleaning belt 20 , the convex ring portion 20 a keeps extending into the annular recessed area 11 a .

[0047] When the cleaning robot moves, in some cases, such as when turning, a displacement difference is generated on both sides perpendicular to its moving direction, so that the cleaning belt 20 has a tendency to move in the axial direction, and the convex ring portion 20a cooperates with the annular recessed area 11a to limit the cleaning belt 20 in the axial direction. 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.

[0048] The axial direction mentioned in this specification refers to the axial direction of the roller 11 .

[0049] The number of the annular recessed areas 11 a on each roller 11 is not limited, and may be one, two or more.

[0050] For some examples, see Figure 3 , the roller 11 is provided with annular recessed areas 11a at opposite ends along the axial direction, and the cleaning belt 20 is provided with convex ring parts 20a at opposite ends along the axial direction. That is, the number of the annular recessed areas 11a is at least two, the number of the convex ring parts 20a is at least two, and the convex ring parts 20a and the annular recessed areas 11a that cooperate with each other are provided at the end positions of the cleaning assembly 100 along the axial direction, which can more effectively suppress the side slip of the cleaning belt 20 caused by the end displacement difference, and reduce the probability of the cleaning belt 20 being lifted or arched.

[0051] The form of the annular depression 11a is not limited, please refer to Figure 5 , which may be a groove opened on the peripheral surface of the roller 11, and the convex ring portion 20a extends into the groove.

[0052] In some other embodiments, please refer to Figure 4 The roller 11 includes a first shaft section 111 and a second shaft section 112 arranged in the axial direction, and the outer diameter of the second shaft section 112 is smaller than the outer diameter of the first shaft section 111, so as to form an annular recessed area 11a in the outer periphery of the second shaft section 112. In this embodiment, the end surface of the first shaft section 111 in the axial direction (at b in the figure) can abut against the convex ring portion 20a, thereby achieving a limiting effect.

[0053] In some embodiments where two annular recessed areas 11a are provided on each roller 11, the second shaft section 112 is provided at opposite ends of the first shaft section 111 in the axial direction, and two annular recessed areas 11a are formed correspondingly. There are two convex ring portions 20a, and the two end faces of the first shaft section 111 in the axial direction are respectively in contact with the two convex ring portions 20a. In other words, the two end faces of the first shaft section 111 in the axial direction have a limiting effect on the cleaning belt 20 in opposite directions. In other words, the convex ring portions 20a of the cleaning belt 20 are in contact with the two ends of the first shaft section 111 in the axial direction, thereby enhancing the limiting effect.

[0054] For some examples, see Figure 2 and Figure 4 The bracket 12 includes a support portion 12a, which is disposed at the end of the bracket 12 in the axial direction. One end of the roller 11 is rotatably supported on the support portion, and the second shaft section 112 extends to the support portion 12a away from one end of the first shaft section 111, and the support portion 12a and the end surface of the second shaft section 112 are spaced apart.

[0055] like Figure 4As shown, the support portion 12a, the end surface of the second shaft segment 112 and at least part of the outer peripheral surface of the second shaft segment 112 together define an annular recessed area 11a. In this embodiment, on the one hand, the support portion 12a has a limiting effect on the cleaning belt 20, and on the other hand, the support portion 12a can have a larger size structure, which is conducive to providing more stable support for the roller 11.

[0056] For some examples, see Figure 4 , the end of the convex ring portion 20a away from the first shaft section 111 is spaced from the support portion 12a. That is, there is a certain gap between the end of the convex ring portion 20a away from the first shaft section 111 and the support portion 12a, so that the cleaning belt 20 is not easy to be scratched with the support portion 12a during movement, thereby reducing the influence of the support portion 12a on the movement of the cleaning belt 20.

[0057] For some examples, see Figure 4 The roller 11 also includes a third shaft segment 113, one end of the third shaft segment 113 is connected to the second shaft segment 112, and the other end is connected, penetrated and supported by the support portion 12a. The outer diameter of the third shaft segment 113 is smaller than the outer diameter of the second shaft segment 112, and the end surface of the second shaft segment 112 is used to contact the support portion 12a with a stopper.

[0058] The third shaft section 113 can be used to connect with the motor to provide driving force. The cross-section of the third shaft section 113 perpendicular to the axial direction can be rectangular or polygonal, which is conducive to transmitting the power of the motor.

[0059] In this embodiment, the outer diameter gradually increases from the third shaft segment 113 to the first shaft segment 111 , which is beneficial to the processing of the roller 11 ; and the end face of the second shaft segment 112 can fix its axial position relative to the bracket 12 , which is beneficial to the assembly of the roller 11 .

[0060] The shape of the protruding ring portion 20a of the cleaning belt 20 is not limited. For example, in some embodiments, along the direction close to the roller 11, the width of the protruding ring portion 20a along the axial direction of the roller 11 remains unchanged, so that the protruding ring portion 20a is better attached to the end of the annular recessed area 11a.

[0061] In some other embodiments, please refer to Figure 4 Along the direction approaching the roller 11, the width of the convex ring portion 20a along the axial direction of the roller 11 decreases gradually. This not only enhances the shear resistance of the root of the convex ring portion 20a along the direction away from the roller 11, but also plays a guiding role. When installing the cleaning belt 20, it is convenient for the convex ring portion 20a to extend into the annular recessed area 11a.

[0062] In some embodiments, the axial edge of the cleaning belt 20 along the roller 11 is flush with the axial edge of the bracket 12 along the roller 11, thereby increasing the axial size of the cleaning belt and improving its cleaning area and cleaning efficiency.

[0063] Correspondingly, in some embodiments where the bracket 12 has a supporting portion 12a, as shown in FIG. Figure 4 As shown, the cleaning tape 20 covers the supporting portion 12 a so that the edge of the cleaning tape 20 along the axial direction of the roller 11 is flush with the edge of the bracket 12 along the axial direction of the roller 11 .

[0064] It should be noted that the structure of the supporting device 10 of the cleaning assembly 100 provided in the embodiment of the present application is not limited, and can be fixed or foldable.

[0065] See also Figure 2 In some embodiments, the bracket 12 includes 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 another roller 11 is rotatably disposed on the second bracket 122. 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.

[0066] See also Figure 6 In the unfolded state, the two rollers 11 tension the cleaning belt 20; see Figure 7 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.

[0067] 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 folded, 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.

[0068] In addition, the foldable support device 10 is not only convenient for installing the cleaning belt 20, but also can be folded to avoid the dimensional interference between the support device 10 and the cleaning belt 20 when installing the cleaning belt 20, so that the design of the convex ring portion 20a and the annular recessed area 11a is more flexible.

[0069] 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.

[0070] It should be noted that when the distance between the two rollers 11 is the smallest, the device is in a folded state; and when the distance between the two rollers 11 is the largest, the device is in an unfolded state.

[0071] That is to say, 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.

[0072] For some examples, see Figure 6 and Figure 7 One of the first bracket 121 and the second bracket 122 has at least one stop protrusion 12b, and the other has at least one positioning recess 12c. The stop protrusion 12b and the positioning recess 12c have a limiting effect when they cooperate, so that the first bracket 121 and the second bracket 122 are relatively fixed.

[0073] In the unfolded state, the stop protrusion 12b cooperates with one positioning recess 12c to keep the bracket 12 in the unfolded state. Further, the number of the positioning recesses 12c is at least two, and in the folded state, the stop protrusion 12b cooperates with another positioning recess 12c to keep the bracket 12 in the folded state, so that the user can disassemble it more conveniently and labor-savingly.

[0074] 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 vibration or sound and other sensory information when the stop protrusion 12b cooperates with the positioning recess 12c, 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.

[0075] For some examples, see Figure 7 The first bracket 121 is rotatably connected to the second bracket 122 , and the two rotate relative to each other around an axis, and the rotation axis and the axes of the two rollers 11 are parallel to each other.

[0076] 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.

[0077] 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 axis can be used as a fulcrum to exert force on the first bracket 121 or the second bracket 122, and the first bracket 121 and the second bracket 122 can be easily rotated relative to each other by using the force-saving effect of the lever.

[0078] 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.

[0079] The various embodiments / implementations provided in this application can be combined with each other without causing any contradiction.

[0080] 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.
