DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In the present application, unless otherwise specified, the directional words used, such as "up", "down", "left", and "right", generally refer to the up, down, left, and right of the device in actual use or working state, specifically the drawing direction in the accompanying drawings.

[0033] In this application, unless otherwise specified or limited, terms such as "connected," "connected," and "stacked" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integration; they may refer to direct connections or indirect connections through an intermediate medium; they may refer to internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0034] The present application provides a cleaning device and a driving mechanism thereof, which are described in detail below. It should be noted that the order in which the following embodiments are described does not limit the preferred order of the embodiments of the present application. In addition, in the following embodiments, the description of each embodiment has its own emphasis. For parts not described in detail in one embodiment, please refer to the relevant description of other embodiments.

[0035] Please refer to FIG1 , which is a schematic structural diagram of an embodiment of a driving mechanism of the cleaning device of the present application.

[0036] In one embodiment, the cleaning device may be a cleaning robot with cleaning functions such as scrubbing, mopping, and wiping. The cleaning device can automatically move over the surface to be cleaned to sweep and remove dust. Furthermore, the cleaning device of this embodiment can also scrub the surface to be cleaned. The surface to be cleaned may be the ground, or the surface of an object to be cleaned.

[0037] The cleaning device includes a main body. This is the primary component of the cleaning device, used to support and protect the remaining components. Optionally, the main body may be equipped with a mechanism for driving the cleaning device, such as drive wheels or tracks. Furthermore, the main body may be equipped with a wiping element such as a roller brush, and may also have a dust collection function.

[0038] The cleaning device also includes a cleaning assembly, which is used to clean the surface to be cleaned. Specifically, when the cleaning device is applied to a cleaning robot, the cleaning assembly can adopt a rotatable design, that is, the cleaning assembly rotates around its own central axis to scrub the surface to be cleaned. Optionally, the cleaning assembly can include a rotatable cleaning member, etc. For example, the cleaning assembly includes a cleaning disc and a cleaning member disposed on the cleaning disc, and the cleaning member can be a wiping member such as a rag. Of course, in other embodiments of the present application, the cleaning assembly can also include a roller brush, a brush, etc., which is not limited here.

[0039] The cleaning device also includes a drive mechanism 10. The drive mechanism 10 is in transmission connection with the cleaning assembly. The drive mechanism 10 is used to drive the cleaning assembly to rotate to perform cleaning operations. The drive mechanism 10 is also used to drive the cleaning assembly to swing. When the cleaning device needs to clean the corners of the surface to be cleaned, the drive mechanism 10 drives the cleaning assembly to swing outward relative to the device body. When the cleaning device does not need to clean the corners of the surface to be cleaned, the drive mechanism 10 drives the cleaning assembly to swing inward relative to the device body.

[0040] Please also refer to Figures 2a-2c, which are schematic diagrams of the structure of the swinging process of an embodiment of the swinging assembly of the present application. Figures 2a-2c show the bottom view of the drive mechanism 10 shown in Figure 1. The following describes the drive mechanism 10 of the embodiment of the present application.

[0041] In one embodiment, the driving mechanism 10 includes a driving component 11, which is connected to the device body. The driving mechanism 10 also includes a swinging component 12, which is transmission-connected to the driving component 11. The swinging component 12 has an output end 121, and the output end 121 of the swinging component 12 is transmission-connected to the cleaning component. The swinging component 12 drives the cleaning component to perform cleaning work through its output end 121. In addition, the driving component 11 is used to drive the swinging component 12 to swing around a first preset axis (as shown by the dotted line O1 in Figure 1, the same below), so as to drive the cleaning component to swing around the first preset axis through the swinging component 12, so that the cleaning component can be swung out or in relative to the device body of the cleaning device. Figures 2a to 2c show the process of the output end 121 of the swinging component 12 swinging from the right to the left, and the swinging direction is shown by the dotted arrows in Figures 2a and 2b.

[0042] The drive assembly 11 includes a drive shaft 111. The drive shaft 111 is rotatably connected to the device body, and the drive shaft 111 is transmission-connected to the swing assembly 12. The drive assembly 11 also includes a drive gear 112. The drive gear 112 is transmission-connected to the drive shaft 111, and the drive gear 112 is used to drive the swing assembly 12 to swing around a first preset axis through the drive shaft 111. The drive assembly 11 also includes a power member, which is transmission-coordinated with the drive gear 112 to drive the drive shaft 111 to rotate around the first preset axis through the drive gear 112, wherein the first preset axis is the central axis of the drive shaft 111, and the swing assembly 12 is then driven to swing around the first preset axis through the drive shaft 111.

[0043] Please refer to FIG. 3 , which is a schematic structural diagram of an embodiment of the first shielding plate of the present application.

[0044] In one embodiment, the driving mechanism 10 further includes a first shielding plate 13. The first shielding plate 13 can shield the internal structure of the cleaning device and prevent foreign matter from entering the cleaning device, and also beautify the appearance of the cleaning device.

[0045] Specifically, the first baffle 13 is rotatably connected to the main body of the device. The first baffle 13 is provided with a first track groove 131, and the output end 121 of the swing assembly 12 is movably embedded in the first track groove 131. The output end 121 of the swing assembly 12 cooperates with the first track groove 131 to drive the first baffle 13 to rotate around the second preset axis (as shown by the dotted line O2 in Figure 1, the same below). Among them, the first preset axis and the second preset axis are parallel to each other, and the first track groove 131 extends in a direction close to the second preset axis, that is, the first track groove 131 is a waist-shaped groove. In the process of the swing assembly 12 swinging around the first preset axis, the output end 121 of the swing assembly 12 cooperates with the first track groove 131 to drive the first baffle 13 to rotate around the second preset axis, and at the same time, the output end 121 of the swing assembly 12 moves synchronously along the first track groove 131.

[0046] In this manner, the first and second predetermined axes of this embodiment are parallel to each other, meaning that the rotational center of the swing assembly 12 is not concentric with the rotational center of the first shielding plate 13. This facilitates the placement of the drive mechanism 10 within the cleaning device. Furthermore, the first track groove 131 of the first shielding plate 13 of this embodiment extends in a direction close to the second predetermined axis, thus preventing motion interference and resulting jamming between the swing assembly 12 and the first shielding plate 13.

[0047] Furthermore, the first track groove 131 of the first shielding plate 13 extends toward the second predetermined axis, i.e., the centerline of the first track groove 131 passes through the second predetermined axis. This minimizes the size of the first track groove 131 while ensuring sufficient travel for the output end 121 of the swing assembly 12 within the first track groove 131. This simplifies the groove cutting process for the first track groove 131 and prevents the structural reliability of the first shielding plate 13 from being compromised by an oversized first track groove 131.

[0048] Furthermore, referring to FIG. 4 , the distance H between the first preset axis and the second preset axis can be 15 mm to 25 mm, for example, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, 20 mm, 21 mm, 22 mm, 23 mm, 24 mm, 25 mm, etc. Thus, by properly setting the distance between the first preset axis and the second preset axis, this embodiment can further facilitate the arrangement of the drive mechanism 10 in the cleaning device.

[0049] Please refer to FIG. 5 , which is a schematic structural diagram of an embodiment of a substrate of the present application.

[0050] In one embodiment, the drive mechanism 10 further includes a base plate 15. The base plate 15 is connected to the device body; specifically, the base plate 15 and the device body are fixed to each other. The first shielding plate 13 is configured to rotate relative to the base plate 15 about a second predetermined axis. The base plate 15 is provided with a second track groove 151, and the output end 121 of the swing assembly 12 sequentially passes through the first track groove 131 and the second track groove 151. As the swing assembly 12 swings about the first predetermined axis, the output end 121 of the swing assembly 12 moves about the first predetermined axis within the second track groove 151.

[0051] The orthographic projection of the first shielding plate 13 on the base plate 15 overlaps with the second track groove 151. In other words, in this embodiment, the first shielding plate 13 shields the internal structure of the cleaning device exposed by the second track groove 151, and prevents foreign matter from entering the cleaning device through the second track groove 151. Furthermore, as the output end 121 of the swing assembly 12 moves within the second track groove 151, the first shielding plate 13 can shield the second track groove 151 beyond the position where the output end 121 of the swing assembly 12 is located.

[0052] It should be noted that the first baffle 13 is located on the side of the substrate 15 facing the drive mechanism 10, that is, the first baffle 13 is located on the inner side of the substrate 15. The swing assembly 12 is located on the side of the substrate 15 facing the drive mechanism 10, that is, the swing assembly 12 is located on the inner side of the substrate 15. The cleaning assembly is transmission-connected to the swing assembly 12 on the side of the substrate 15 facing away from the drive mechanism 10. Therefore, in this embodiment, the first track groove 131 is provided along the second preset axis and passes through the first baffle 13, and the second track groove 151 is provided along the first preset axis and passes through the substrate 15, so that the output end 121 of the swing assembly 12 can pass through the first track groove 131 and the second track groove 151 and be transmission-connected to the cleaning assembly.

[0053] Furthermore, the second track groove 151 extends circumferentially about the first predetermined axis. This minimizes the size of the second track groove 151 while ensuring that the output end 121 of the swing assembly 12 has sufficient travel within the second track groove 151. This simplifies the groove forming process for the second track groove 151 and prevents the structural reliability of the base plate 15 from being compromised by an oversized second track groove 151.

[0054] Furthermore, the drive mechanism 10 also has a reference plane perpendicular to the second preset axis (as shown by plane α in FIG. 4 , and the same below). During the rotation of the first baffle 13 about the second preset axis, the orthographic projection of the first baffle 13 on the reference plane lies within the orthographic projection of the substrate 15 on the reference plane. In other words, during the rotation of the first baffle 13 about the second preset axis, the first baffle 13 never exceeds the coverage of the substrate 15. This prevents the rotation of the first baffle 13 from occupying too much internal space of the cleaning device and prevents the first baffle 13 from failing to effectively block the second track groove 151, further facilitating the placement of the drive mechanism 10 within the cleaning device.

[0055] Optionally, the orthographic projection of the substrate 15 on the reference plane may be a circle, etc., and the second preset axis passes through the center of the substrate 15 , that is, the rotation center of the first shielding plate 13 is concentric with the center of the substrate 15 .

[0056] Please refer to FIG. 6 , which is a schematic structural diagram of an embodiment of the second shielding plate of the present application.

[0057] In one embodiment, the driving mechanism 10 further includes a second baffle 14. The second baffle 14 is provided with a transmission hole 141, and the output end 121 of the swing assembly 12 is also embedded in the transmission hole 141. The output end 121 of the swing assembly 12 cooperates with the transmission hole 141 to drive the second baffle 14 to rotate around the first preset axis. The orthographic projection of the second baffle 14 on the first baffle 13 overlaps with the first track groove 131. Since the first track groove 131 adopts a waist-shaped groove design, the first track groove 131 will inevitably expose the internal structure of the cleaning device to a certain extent. In this embodiment, the second baffle 14 blocks the internal structure of the cleaning device exposed by the first track groove 131, and the second baffle 14 prevents external foreign matter from entering the interior of the cleaning device through the first track groove 131.

[0058] It should be noted that in this embodiment, the diameter of the transmission hole 141 is set to be slightly larger than the outer diameter of the output end 121 of the oscillating assembly 12. This allows the output end 121 of the oscillating assembly 12 to be inserted into the transmission hole 141 without exposing the internal structure of the cleaning device. Furthermore, the transmission hole 141 extends through the second baffle 14 along the first predetermined axis. The base plate 15 and the second baffle 14 are stacked on either side of the first baffle 13 along the second predetermined axis. The output end 121 of the oscillating assembly 12 passes through the transmission hole 141, the first track groove 131, and the second track groove 151 in sequence.

[0059] In the embodiment of the present application, the rotation center of the swing assembly 12 is arranged to be non-concentric with the rotation center of the first baffle plate 13 to facilitate the arrangement of the drive mechanism 10 in the cleaning device; and, in the embodiment of the present application, the first track groove 131 of the first baffle plate 13 is arranged to extend in a direction close to the second preset axis to avoid motion interference and jamming between the swing assembly 12 and the first baffle plate 13; in addition, in the embodiment of the present application, a second baffle plate 14 is additionally provided to shield the internal structure of the cleaning device exposed by the first track groove 131, thereby solving the problem of missing shielding caused by the waist-shaped groove design of the first track groove 131 of the first baffle plate 13.

[0060] Furthermore, the drive mechanism 10 also has a first width direction (as shown by arrow X in FIG3 , the same below) and a second width direction (as shown by arrow Y in FIG6 , the same below). The first width direction is perpendicular to the second preset axis and the relative direction between the second preset axis and the first track groove 131, and the second width direction is perpendicular to the first preset axis and the relative direction between the first preset axis and the transmission hole 141. Among them, the length D of the first track groove 131 in the first width direction is less than or equal to the length d of the second baffle 14 in the second width direction at the position of the transmission hole 141. In this way, it can be ensured that the second baffle 14 effectively blocks the internal structure of the cleaning device exposed by the first track groove 131.

[0061] Furthermore, the second shielding plate 14 includes a shielding portion 142 and a connecting portion 143. The shielding portion 142 is provided with a transmission hole 141. The length D of the first track groove 131 in the first width direction is less than or equal to the length d of the shielding portion 142 in the second width direction, so that the shielding portion 142 can effectively shield the internal structure of the cleaning device exposed by the first track groove 131. The connecting portion 143 is connected to the side of the shielding portion 142 close to the first preset axis. Among them, the length of the connecting portion 143 in the second width direction is less than the length of the shielding portion 142 in the second width direction, which can reduce the material used in the second shielding plate 14, thereby helping to reduce the weight and cost of the driving mechanism 10.

[0062] In one embodiment, the second shielding plate 14 is also connected to the drive shaft 111 of the drive assembly 11. In this embodiment, the cleaning assembly is connected to the drive shaft 111 via the swing assembly 12. The cleaning assembly, swing assembly 12, and drive shaft 111 form a structure similar to a cantilever beam. Therefore, in this embodiment, the second shielding plate 14 is connected to the drive shaft 111 at one end and to the output end 121 of the swing assembly 12 at the other end. This strengthens the structural strength of the drive mechanism 10 and, in turn, improves its operational stability.

[0063] The technical solutions provided in the embodiments of this application are described below in conjunction with specific application scenarios.

[0064] Application scenario 1:

[0065] The cleaning device is a cleaning robot that can automatically move over a surface to be cleaned to clean, remove dust, and scrub the surface it passes over. The cleaning device includes a device body. The cleaning device also includes a drive mechanism 10. The drive mechanism 10 includes a drive assembly 11, which is connected to the device body. The drive mechanism 10 also includes a swing assembly 12, which is transmission-connected to the drive assembly 11 and configured to drive the swing assembly 12 to swing about a first preset axis, wherein the swing assembly 12 has an output end 121. The cleaning device also includes a cleaning assembly, which is transmission-connected to the output end 121 of the swing assembly 12 and drives the cleaning assembly via its output end 121 to perform cleaning operations. When the cleaning device needs to clean the corners of the surface to be cleaned, the drive mechanism 10 drives the cleaning assembly to swing outward relative to the device body. When the cleaning device does not need to clean the corners of the surface to be cleaned, the drive mechanism 10 drives the cleaning assembly to swing inward relative to the device body.

[0066] The drive mechanism 10 also includes a base plate 15, a first baffle 13, and a second baffle 14. The base plate 15 is fixed to the device body. The first baffle 13 is configured to rotate relative to the base plate 15 about a second preset axis. The first baffle 13 is provided with a first track groove 131, which extends toward the second preset axis. The base plate 15 is provided with a second track groove 151, which extends circumferentially along the first preset axis. The second baffle 14 is provided with a transmission hole 141. The output end 121 of the swing assembly 12 passes through the transmission hole 141, the first track groove 131, and the second track groove 151 in sequence. When the drive assembly 11 drives the swing assembly 12 to swing about the first preset axis, the output end 121 of the swing assembly 12 moves along the second track groove 151, and at the same time, the output end 121 of the swing assembly 12 synchronously drives the first baffle 13 to rotate about the second preset axis and the second baffle 14 to rotate about the first preset axis.

[0067] The rotation center of the swing assembly 12 is not concentric with the rotation center of the first baffle plate 13, so as to facilitate the arrangement of the driving mechanism 10 in the cleaning device; and the first track groove 131 of the first baffle plate 13 extends in a direction close to the second preset axis to avoid motion interference and jamming between the swing assembly 12 and the first baffle plate 13; in addition, the second baffle plate 14 blocks the internal structure of the cleaning device exposed by the first track groove 131, solving the problem of missing shielding due to the waist-shaped groove design of the first track groove 131 of the first baffle plate 13.

[0068] Application scenario 2:

[0069] The driving mechanism 10 is applied to a cleaning device. The driving mechanism 10 includes a driving assembly 11. The driving mechanism 10 also includes a swinging assembly 12, which is transmission-connected to the driving assembly 11. The driving assembly 11 is used to drive the swinging assembly 12 to swing around a first preset axis, wherein the swinging assembly 12 has an output end 121. The cleaning assembly of the cleaning device is transmission-connected to the output end 121 of the swinging assembly 12, and the swinging assembly 12 drives the cleaning assembly to perform cleaning work through its output end 121. When the cleaning device needs to clean the corner areas of the surface to be cleaned, the driving mechanism 10 drives the cleaning assembly to swing out toward the outside of the cleaning device relative to the device body of the cleaning device, and when the cleaning device does not need to clean the corner areas of the surface to be cleaned, the driving mechanism 10 drives the cleaning assembly to swing in toward the inside of the cleaning device relative to the device body.

[0070] The drive mechanism 10 also includes a base plate 15, a first baffle 13, and a second baffle 14. The base plate 15 is fixed to the device body. The first baffle 13 is configured to rotate relative to the base plate 15 about a second preset axis. The first baffle 13 is provided with a first track groove 131, which extends toward the second preset axis. The base plate 15 is provided with a second track groove 151, which extends circumferentially along the first preset axis. The second baffle 14 is provided with a transmission hole 141. The output end 121 of the swing assembly 12 passes through the transmission hole 141, the first track groove 131, and the second track groove 151 in sequence. When the drive assembly 11 drives the swing assembly 12 to swing about the first preset axis, the output end 121 of the swing assembly 12 moves along the second track groove 151, and at the same time, the output end 121 of the swing assembly 12 synchronously drives the first baffle 13 to rotate about the second preset axis and the second baffle 14 to rotate about the first preset axis.

[0071] The rotation center of the swing assembly 12 is not concentric with the rotation center of the first baffle plate 13, so as to facilitate the arrangement of the driving mechanism 10 in the cleaning device; and the first track groove 131 of the first baffle plate 13 extends in a direction close to the second preset axis to avoid motion interference and jamming between the swing assembly 12 and the first baffle plate 13; in addition, the second baffle plate 14 blocks the internal structure of the cleaning device exposed by the first track groove 131, solving the problem of missing shielding due to the waist-shaped groove design of the first track groove 131 of the first baffle plate 13.
