Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0034] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meanings as those generally understood by those of ordinary skill in the art. Some technical terms appearing in the embodiments of the present application are explained below.
[0035] In order to make the technical solutions and advantages of the present application more clear, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.
[0036] like Figures 1 to 5 As shown, an embodiment of the present application provides a sweeping robot, including a shell 1, a rag tray 2, a first driving member 3 and a second driving member 4.
[0037] The housing 1 has a housing cavity 11, which is used to accommodate various components of the sweeping robot. The orthographic projection contour of the housing 1 can be circular, elliptical, polygonal, etc. The embodiment of the present application only takes the orthographic projection shape of the housing 1 as an example for explanation. It can be understood that the orthographic projection of the housing 1 is a projection obtained by projecting the housing 1 with parallel light parallel to the height direction of the housing 1.
[0038] The rag tray 2 is arranged at the bottom of the housing 1. Figure 3 As shown, the rag plate 2 is located outside the shell 1 and below the shell 1, and a wiping component such as a rag is provided on the side of the rag plate 2 away from the shell 1, which facilitates the wiping component to clean or mop the floor.
[0039] The first driving member 3 is installed in the accommodating cavity 11 . The first driving member 3 includes a first output shaft connected to the rag plate 2 . The first driving member 3 is used to drive the rag plate 2 to rotate around the first output shaft.
[0040] Exemplarily, the rag tray 2 is in the shape of a disc.
[0041] For example, the first driving member 3 is a rotary motor and the first output shaft is coaxially arranged with the central axis of the rag plate 2. The first driving member 3 can drive the rag plate 2 to rotate around the central axis of the rag plate 2, thereby improving the cleaning ability of the mopping component, so that the mopping component can clean the floor evenly and fully. Alternatively, the first output shaft and the central axis of the rag plate 2 are eccentrically arranged, so that the first driving member 3 drives the rag plate 2 to produce an eccentric motion around the first output shaft.
[0042] Optionally, the first driving member 3 can drive the rag plate 2 to rotate around its own central axis, and can also drive the rag plate 2 to rise and fall along the height direction of the shell 1.
[0043] The second driving member 4 is installed in the accommodating chamber 11 and includes a second output shaft 41 connected to the first driving member 3 . The second driving member 4 is used to drive the first driving member 3 and the rag plate 2 to move so that the rag plate 2 extends or retracts relative to the outer wall 14 of the shell 1 .
[0044] like Figure 1 As shown, when the rag plate 2 is retracted relative to the outer side wall 14 of the housing 1, in the orthographic projection of the sweeping robot, most or all of the contour line of the rag plate 2 is located within the space formed by the contour line of the housing 1, saving space occupied in the horizontal direction and avoiding collision with obstacles. It should be noted that the "horizontal" direction mentioned in the embodiments of the present application is the direction parallel to the ground when the sweeping robot is in normal working state.
[0045] like Figure 2 As shown, when the rag plate 2 is extended relative to the outer side wall 14 of the shell 1, in the orthographic projection of the sweeping robot, most or all of the contour line of the rag plate 2 is located outside the space formed by the contour line of the shell 1. For example, the contour line of the rag plate 2 is tangent to the contour line of the shell 1, so as to facilitate the wiping part of the rag plate 2 to fully clean the wall or corners.
[0046] Specifically, the second driving member 4 directly drives the first driving member 3 to move, and then drives the rag plate 2 to move. There is no need to set intermediate transmission structures such as gears and connecting rods between the first driving member 3 and the second driving member 4, so the extension and retraction of the rag plate 2 can be achieved more easily, which greatly simplifies the structure of the sweeping robot and can reduce the probability of failure when the rag plate 2 is extended due to failure of the transmission structure.
[0047] The sweeping robot provided in the embodiment of the present application is connected with the first driving member 3 by setting a second driving member 4. When it is necessary to clean the wall or the corner, the second driving member 4 is used to drive the first driving member 3 and the rag plate 2 to move, so that the rag plate 2 is extended relative to the outer wall 14 of the shell 1, so that the rag plate 2 can fully clean the wall or the corner; when the rag plate 2 completes the cleaning of the wall or the corner, the second driving member 4 drives the rag plate 2 to retract relative to the outer wall 14 of the shell 1, so as to reduce the space occupied by the rag plate 2; the rag is directly driven by the second driving member 4 to achieve edge cleaning, eliminating intermediate transmission structures such as gears and connecting rods, and having a simple structure. It is not easy to have transmission failure, jamming and the like, thereby prolonging the service life of the sweeping robot and reducing the production cost, which is conducive to improving the user experience.
[0048] Among them, the second driving member 4 can be a rotating motor, a linear motor, etc. The second driving member 4 can realize the extension and retraction of the rag plate 2 by driving the first driving member 3 and the rag plate 2 to move linearly, and can also realize the extension and retraction of the rag plate 2 by driving the first driving member 3 and the rag plate 2 to rotate.
[0049] In an optional embodiment, the second driving member 4 is a rotating motor, the first driving member 3 and the second driving member 4 are stacked, and the second output shaft 41 is used to drive the first driving member 3 and the rag plate 2 to rotate, thereby extending or retracting the rag plate 2 relative to the outer wall 14 of the shell 1.
[0050] Exemplarily, the second driving member 4 is a stepper motor. After the second driving member 4 is started, a certain number of electric pulse signals are input to convert the second driving member 4 into a corresponding angular displacement, and the corresponding torque is output to drive the first driving member 3 to rotate a corresponding angle, so that the rag plate 2 rotates around the rotation center axis of the first driving member 3 as a whole by the same angle, and then extends relative to the outer wall 14 of the housing 1; the second driving member 4 is reversed to achieve the reverse rotation of the rag plate 2, and then the rag plate 2 is retracted relative to the outer wall 14 of the housing 1. In this embodiment, the number of pulses can achieve the positioning of the rag plate 2 when it is extended and retracted.
[0051] Exemplarily, the second driving member 4 is located above the first driving member 3 , the first driving member 3 is located above the rag plate 2 , and the second output shaft 41 is directly connected to the top of the first driving member 3 to avoid interference with the rag plate 2 .
[0052] In a further embodiment, a first rotating shaft 31 is disposed on one side surface of the first driving member 3 in the height direction, and the second output shaft 41 is coaxially connected to the first rotating shaft 31 .
[0053] For example, Figure 4As shown, the first rotating shaft 31 is protruded from the upper surface of the first driving member 3 , that is, the side surface of the first rotating member facing away from the rag plate 2 , and the second driving member 4 is located above the first driving member 3 .
[0054] Exemplarily, the second output shaft 41 is connected to the first rotating shaft 31 by plugging, and torque is transmitted by key connection, fasteners, interference fit, etc. to prevent relative sliding between the two.
[0055] In this embodiment, the first driving member 3 rotates around the central axis of the first rotating shaft 31 driven by the second driving member 4, so that the rag plate 2 moves around the central axis of the first rotating shaft 31, thereby changing the relative position of the rag plate 2 and the shell 1, thereby realizing the rotation or retraction of the rag plate 2.
[0056] In an optional embodiment, the second output shaft 41 is coaxially arranged with the first output shaft, and the first output shaft is eccentrically arranged on the rag plate 2, that is, the first output shaft and the central axis of the rag plate 2 are spaced apart, so that when the first output shaft rotates, the relative position of the rag plate 2 and the shell 1 changes, thereby realizing the extension or retraction of the rag plate 2.
[0057] In another optional embodiment, the center line of the first output shaft and the center line of the second output shaft 41 are spaced apart, and the first output shaft is coaxially arranged with the center axis of the rag tray 2 .
[0058] In this embodiment, the first output shaft and the central axis of the rag plate 2 are coaxially arranged, so that the first driving member 3 can drive the rag plate 2 to rotate around its own central axis, thereby realizing rotational cleaning of the rag plate 2; when the second driving member 4 drives the first driving member 3 to rotate around its own output shaft, the rag plate 2 moves around the first output shaft, thereby changing the relative position of the rag plate 2 and the shell 1, thereby realizing the rotation out or retraction of the rag plate 2.
[0059] In a further embodiment, the first driving member 3 further includes a second rotating shaft 32, which is disposed on a side surface of the first driving member 3 away from the first rotating shaft 31. The housing 1 further includes a sleeve 15 disposed in the accommodating cavity 11, and the second rotating shaft 32 is rotatably inserted in the sleeve 15.
[0060] In this embodiment, the matching connection between the second rotating shaft 32 and the sleeve 15 provides support and limiting functions for the first driving member 3, and also reduces the rotational friction between the first driving member 3 and the shell 1, which is beneficial to ensure that the first driving member 3 can rotate flexibly around its own output shaft.
[0061] Optionally, a rolling bearing is provided in the shaft sleeve 15 , which is beneficial to ensuring the rotation accuracy of the first driving member 3 and reducing the friction and energy loss during the rotation of the first driving member 3 .
[0062] In a further embodiment, the second rotating shaft 32 is disposed on a side surface of the first driving member 3 close to the rag tray 2 .
[0063] like Figure 3 and Figure 4 As shown, the first rotating shaft 31 is arranged on the upper surface of the first driving member 3, and the second rotating shaft 32 is arranged on the lower surface of the first driving member 3. The center line of the first rotating shaft 31 coincides with the center line of the second rotating shaft 32. When the second driving member 4 drives the first driving member 3 to rotate around its own output shaft, the second rotating shaft 32 rotates in the sleeve 15. The second rotating shaft 32 can support the bottom of the first driving member 3 and prevent the first driving member 3 from being skewed or offset.
[0064] In a specific embodiment, the housing 1 further includes an upper cover 12 and a bottom plate 13 , which are coupled to form a receiving chamber 11 , the second driving member 4 is mounted on the upper cover 12 , and the sleeve 15 is mounted on the bottom plate 13 .
[0065] In this embodiment, the upper cover 12 and the bottom plate 13 are matched to form the accommodating chamber 11, which is convenient for installation and disassembly. The second driving member 4 is fixed on the upper cover 12, which is convenient for connection with the first rotating shaft 31. Figure 4 As shown, the second driving member 4 is close to the edge area of the upper cover 12, and the second driving member 4 is fixed to the upper cover 12 by fasteners such as screws 5. Figure 4 As shown, the sleeve 15 is disposed on the chassis 13, and the sleeve 15 is used for inserting the second rotating shaft 32, so as to support and limit the first drive.
[0066] In a further embodiment, the housing 1 further includes a guide column 16 and a guide column sleeve 17 , one of the guide column 16 and the guide column sleeve 17 is disposed on the upper cover 12 , and the other is disposed on the chassis 13 , and the guide column 16 is inserted into the guide column sleeve 17 .
[0067] For example, Figure 4 As shown, the guide column 16 is protruded from the chassis 13. Figure 5 As shown, the guide column sleeve 17 is arranged on the upper cover 12. Alternatively, the guide column 16 is convexly arranged on the upper cover 12, and the guide column sleeve 17 is arranged on the chassis 13.
[0068] In this embodiment, the provision of the guide column 16 and the guide column sleeve 17 facilitates quick positioning and connection between the upper cover 12 and the chassis 13, and provides precise guidance for the connection between the second output shaft 41 and the first rotating shaft 31, which helps to improve the assembly efficiency of the sweeping robot.
[0069] In a further embodiment, a limiting groove 131 is provided through the chassis 13 , and the limiting groove 131 is located between the first driving member 3 and the rag plate 2 . The limiting groove 131 is used to limit the movable range of the first driving member 3 and the rag plate 2 .
[0070] The limiting groove 131 passes through the chassis 13 along the thickness direction of the chassis 13, and the first output shaft passes through the limiting groove 131 to be connected with the rag plate 2, or the rag plate 2 passes through the limiting groove 131 to be connected with the first output shaft, and the limiting groove 131 limits the extreme positions of the first driving member 3 and the rag plate 2 in the horizontal direction.
[0071] Exemplarily, when the first driving member 3 and the rag plate 2 are located at the first extreme position, the rag plate 2 is retracted relative to the outer wall 14 of the shell 1, and in the orthographic projection of the sweeping robot, the overlapping area between the rag plate 2 and the shell 1 is the largest; when the first driving member 3 and the rag plate 2 are located at the second extreme position, the rag plate 2 is extended relative to the outer wall 14 of the shell 1, and in the orthographic projection of the sweeping robot, the overlapping area between the rag plate 2 and the shell 1 is the smallest.
[0072] In this embodiment, the limiting groove 131 is provided to limit the range of movement of the first driving member 3 and the rag plate 2 to prevent the rag plate 2 from being over-extended or over-retracted, which helps to ensure that the rag plate 2 moves into place.
[0073] In an optional embodiment, the second driving member 4 is a linear motor, the first driving member 3 and the second driving member 4 are arranged on the same layer, and the second output shaft 41 is used to push or pull the first driving member 3 and the rag plate 2, thereby extending or retracting the rag plate 2 relative to the outer wall 14 of the shell 1.
[0074] Specifically, the first driving member 3 and the second driving member 4 are installed side by side in the accommodating cavity 11, and the second output shaft 41 can move linearly along its own axial direction, thereby driving the first driving member 3 and the rag plate 2 to move.
[0075] Exemplarily, the second output shaft 41 drives the first driving member 3 to move linearly, so that the rag tray 2 extends or retracts linearly relative to the outer side wall 14 of the housing 1. In this embodiment, the second output shaft 41 is fixedly connected to the side wall of the first driving member 3 to ensure the connection strength between the two.
[0076] Alternatively, the second output shaft 41 pushes or pulls the first driving member 3, so that the first driving member 3 and the rag plate 2 generate rotational motion. For example, a rotating shaft is provided at the first end of the first driving member 3, a sliding groove is provided on the side wall of the first driving member 3 close to the second driving member 4, a slider is provided at the end of the second output shaft 41, the slider is embedded in the sliding groove and can move along the length direction of the sliding groove, the second output shaft 41 is close to the second end of the first driving member 3, wherein the first end and the second end are arranged oppositely; when the second output shaft 41 extends in a straight line, the first driving member 3 rotates around the rotating shaft under the push of the second driving member 4, the slider moves relative to the sliding groove, and the rag plate 2 rotates around the rotating shaft with the first driving member 3, thereby rotating out relative to the outer wall 14 of the housing 1; when the second output shaft 41 retracts in a straight line, due to the matching connection between the slider and the sliding groove, the first driving member 3 can generate reverse rotation around the rotating shaft under the pull of the second driving member 4, so that the rag plate 2 rotates around the rotating shaft with the first driving member 3, thereby retracting relative to the outer wall 14 of the housing 1.
