[0033] The present application provides a cleaning device and its driving mechanism, which will be described in detail below. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments of the present application. And in the following embodiments, each embodiment has its own focus. For the parts not detailed in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0034] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of an embodiment of the driving mechanism of the cleaning device of the present application.

[0035] In one embodiment, the cleaning device can be a cleaning robot with cleaning functions such as floor washing, mopping, and floor wiping. The cleaning device can automatically move on the surface to be cleaned to clean and remove dust from the surface to be cleaned it passes through, and the cleaning device in this embodiment can also scrub the surface to be cleaned it passes through. Among them, the surface to be cleaned can be the ground or the surface to be cleaned of an object, etc.

[0036] The cleaning device includes a device main body. The device main body is the main part of the cleaning device, used to carry and protect the rest of the components of the cleaning device. Optionally, the device main body can be provided with a mechanism for driving the cleaning device to walk, such as driving wheels, tracks, etc. And, the device main body can also be provided with a mopping and scrubbing part such as a rotary brush. In addition, the device main body can also have a dust suction function.

[0037] The cleaning device also includes a cleaning component, which is used to clean the surface to be cleaned. Specifically, when the cleaning device is applied to a cleaning robot, the cleaning component can be rotatable, that is, the surface to be cleaned is scrubbed by rotating the cleaning component around its own central axis. Optionally, the cleaning component may include a rotatable cleaning member, etc. For example, the cleaning component includes a cleaning disc and a cleaning member disposed on the cleaning disc, and the cleaning member may be a wiping member such as a rag. Of course, in other embodiments of the present application, the cleaning component may also include a roller brush, a hair brush, etc., which are not limited here.

[0038] The cleaning device further comprises a driving mechanism 10. The driving mechanism 10 is in transmission connection with the cleaning assembly. The driving mechanism 10 is used to drive the cleaning assembly to rotate to perform cleaning work. The driving mechanism 10 is also used to drive the cleaning assembly to swing. When the cleaning device needs to clean the corner area of ​​the surface to be cleaned, the driving mechanism 10 drives the cleaning assembly to swing outward relative to the device body toward the outside of the cleaning device, and when the cleaning device does not need to clean the corner area of ​​the surface to be cleaned, the driving mechanism 10 drives the cleaning assembly to swing inward relative to the device body toward the inside of the cleaning device.

[0039] Please also read Figures 2a-2c , Figures 2a-2c It is a structural schematic diagram of an embodiment of the swing process of the swing assembly of the present application. Figures 2a to 2c Shown is Figure 1 The driving mechanism 10 is shown as a bottom view. The driving mechanism 10 of the embodiment of the present application is described below.

[0040] In one embodiment, the driving mechanism 10 includes a driving component 11, and the driving component 11 is connected to the device body. The driving mechanism 10 also includes a swinging component 12, and the swinging component 12 is in transmission connection with the driving component 11. The swinging component 12 has an output end 121, and the output end 121 of the swinging component 12 is in transmission connection with 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 rotate around a first preset axis (such as Figure 1 The cleaning assembly is driven to swing around the first preset axis through the swing assembly 12, so that the cleaning assembly can swing out or in relative to the device body of the cleaning device. Figures 2a to 2c The output end 121 of the swing assembly 12 swings from the right side to the left side. Figure 2a and Figure 2b Indicated by the dashed arrow.

[0041] The driving assembly 11 includes a driving shaft 111. The driving shaft 111 is rotatably connected to the device main body, and the driving shaft 111 is in transmission connection with the swinging assembly 12. The driving assembly 11 further includes a driving gear 112. The driving gear 112 is in transmission connection with the driving shaft 111, and the driving gear 112 is used to drive the swinging assembly 12 to swing around a first preset axis through the driving shaft 111. The driving assembly 11 further includes a power member, and the power member is in transmission cooperation with the driving gear 112 to drive the driving shaft 111 to rotate around the first preset axis through the driving gear 112, wherein the first preset axis is the central axis of the driving shaft 111, and further drive the swinging assembly 12 to swing around the first preset axis through the driving shaft 111.

[0042] Please refer to Figure 3 , Figure 3 which is a schematic structural diagram of an embodiment of the first baffle plate of the present application.

[0043] In one embodiment, the driving mechanism 10 further includes a first baffle plate 13. The first baffle plate 13 can block the internal structure of the cleaning device and prevent foreign objects from entering the inside of the cleaning device, and also plays a role in beautifying the appearance of the cleaning device product.

[0044] Specifically, the first baffle plate 13 is rotatably connected to the device main body. The first baffle plate 13 is provided with a first track groove 131, and the output end 121 of the swinging assembly 12 is movably embedded in the first track groove 131. The output end 121 of the swinging assembly 12 cooperates with the first track groove 131 to drive the first baffle plate 13 to rotate around a second preset axis (as shown by the dotted line O2 in Figure 1 the same below). Among them, the first preset axis is parallel to the second preset axis, and the first track groove 131 extends along the direction close to the second preset axis, that is, the first track groove 131 is a kidney-shaped groove. During the process of the swinging assembly 12 swinging around the first preset axis, the output end 121 of the swinging assembly 12 cooperates with the first track groove 131 to drive the first baffle plate 13 to rotate around the second preset axis, and at the same time, the output end 121 of the swinging assembly 12 synchronously moves along the first track groove 131.

[0045] In the above manner, in this embodiment, the first preset axis is parallel to the second preset axis, that is, the rotation centers of the swinging assembly 12 and the first baffle plate 13 are not concentric, so that the layout of the driving mechanism 10 in the cleaning device can be facilitated. Moreover, in this embodiment, the first track groove 131 of the first baffle plate 13 extends along the direction close to the second preset axis, so that the movement interference and jamming between the swinging assembly 12 and the first baffle plate 13 can be avoided.

[0046] Further, the first track groove 131 of the first baffle 13 extends toward the second preset axis, that is, the center line of the first track groove 131 passes through the second preset axis. In this way, on the basis of ensuring that the output end 121 of the swing assembly 12 has sufficient stroke in the first track groove 131, the first track groove 131 has the minimum size, so that the grooving process of the first track groove 131 can be simplified, and the structural reliability of the first baffle 13 can be avoided from being affected due to the over-large size of the first track groove 131.

[0047] Further, please refer to Figure 4 simultaneously. The distance H between the first preset axis and the second preset axis can be 15 mm to 25 mm, such as 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, 20 mm, 21 mm, 22 mm, 23 mm, 24 mm, 25 mm, etc. In this way, by reasonably setting the distance between the first preset axis and the second preset axis in this embodiment, the layout of the driving mechanism 10 in the cleaning device can be further facilitated.

[0048] Please refer to Figure 5 , Figure 5 which is a schematic structural diagram of an embodiment of the substrate of the present application.

[0049] In one embodiment, the driving mechanism 10 further includes a substrate 15. The substrate 15 is connected to the device main body, specifically, the substrate 15 and the device main body are fixed to each other. The first baffle 13 is configured to be rotatable relative to the substrate 15 about the second preset axis. The substrate 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. During the process of the swing assembly 12 swinging about the first preset axis, the output end 121 of the swing assembly 12 moves about the first preset axis in the second track groove 151.

[0050] The orthographic projection of the first baffle 13 on the substrate 15 overlaps with the second track groove 151. In other words, in this embodiment, the first baffle 13 shields the internal structure of the cleaning device exposed by the second track groove 151, and the first baffle 13 blocks foreign objects outside from entering the cleaning device through the second track groove 151. And, as the output end 121 of the swing assembly 12 moves in the second track groove 151, the first baffle 13 can shield the second track groove 151 other than the position where the output end 121 of the swing assembly 12 is located.

[0051] It should be noted that the first baffle plate 13 is located on the side of the substrate 15 facing the driving mechanism 10, that is, the first baffle plate 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 driving 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 away from the driving mechanism 10. Therefore, in this embodiment, the first track groove 131 is arranged along the second preset axis to penetrate the first baffle plate 13, and the second track groove 151 is arranged along the first preset axis to penetrate 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.

[0052] Furthermore, the second track groove 151 extends along the circumferential direction of the first preset axis. In this way, on the basis of ensuring that the output end 121 of the swing assembly 12 has sufficient travel in the second track groove 151, the second track groove 151 has a minimum size, thereby simplifying the grooving process of the second track groove 151 and avoiding affecting the structural reliability of the base plate 15 due to the excessive size of the second track groove 151.

[0053] Furthermore, the driving mechanism 10 also has a reference plane (such as Figure 4 In the process of the first shielding plate 13 rotating around the second preset axis, the orthographic projection of the first shielding plate 13 on the reference plane is in the orthographic projection of the substrate 15 on the reference plane. In other words, in the process of the first shielding plate 13 rotating around the second preset axis, the first shielding plate 13 never exceeds the coverage of the substrate 15, which can prevent the rotation of the first shielding plate 13 from occupying too much internal space of the cleaning device and prevent the first shielding plate 13 from failing to effectively shield the second track groove 151, and further facilitate the arrangement of the driving mechanism 10 in the cleaning device.

[0054] Optionally, the orthographic projection of the substrate 15 on the reference plane may be circular, 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 .

[0055] Please also read Figure 6 , Figure 6 It is a structural schematic diagram of an embodiment of the second shielding plate of the present application.

[0056] In one embodiment, the driving mechanism 10 further includes a second shielding plate 14. The second shielding plate 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 shielding plate 14 to rotate around a first preset axis. The orthographic projection of the second shielding plate 14 on the first shielding plate 13 overlaps with the first track groove 131. Since the first track groove 131 is designed as a waist-shaped groove, the internal structure of the cleaning device will inevitably be exposed to a certain extent. In this embodiment, the second shielding plate 14 shields the internal structure of the cleaning device exposed by the first track groove 131, and the second shielding plate 14 blocks foreign objects outside from entering the cleaning device through the first track groove 131.

[0057] It should be noted that the aperture of the transmission hole 141 in this embodiment is set to be slightly larger than the outer diameter of the output end 121 of the swing assembly 12, so that the output end 121 of the swing assembly 12 can pass through the transmission hole 141, and the transmission hole 141 does not expose the internal structure of the cleaning device. Moreover, the transmission hole 141 is arranged to penetrate the second shielding plate 14 along the first preset axis. The substrate 15 and the second shielding plate 14 are respectively stacked on both sides of the first shielding plate 13 on the second preset axis, and the output end 121 of the swing assembly 12 sequentially passes through the transmission hole 141, the first track groove 131, and the second track groove 151.

[0058] In the embodiment of the present application, the rotation center of the swing assembly 12 is set to be non-concentric with the rotation center of the first shielding plate 13 to facilitate the arrangement of the driving mechanism 10 in the cleaning device; moreover, in the embodiment of the present application, the first track groove 131 of the first shielding plate 13 is arranged to extend in the direction close to the second preset axis to avoid the swing assembly 12 and the first shielding plate 13 from getting stuck due to motion interference; in addition, in the embodiment of the present application, a second shielding plate 14 is additionally provided to shield the internal structure of the cleaning device exposed by the first track groove 131, solving the problem of missed shielding caused by the first track groove 131 of the first shielding plate 13 being designed as a waist-shaped groove.

[0059] Further, the driving mechanism 10 also has a first width direction (as shown by the arrow X below, the same applies hereinafter) and a second width direction (as shown by Figure 3 the arrow X below, the same applies hereinafter), and Figure 6As shown by arrow Y below (the same hereinafter). 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 shielding plate 14 at the position where the transmission hole 141 is located in the second width direction. In this way, it can be ensured that the second shielding plate 14 effectively shields the internal structure of the cleaning device exposed by the first track groove 131.

[0060] Furthermore, the second shielding plate 14 includes a shielding portion 142 and a connecting portion 143. The transmission hole 141 is provided in the shielding portion 142. 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 one 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, so that the material used for the second shielding plate 14 can be reduced, which is beneficial to reducing the weight and cost of the driving mechanism 10.

[0061] In an embodiment, the second shielding plate 14 is further connected to the driving shaft 111 of the driving assembly 11. In this embodiment, the cleaning assembly is connected to the driving shaft 111 through the swinging assembly 12, and the cleaning assembly, the swinging assembly 12 and the driving shaft 111 form a structure similar to a cantilever beam. In view of this, one end of the second shielding plate 14 in this embodiment is connected to the driving shaft 111, and the other end is connected to the output end 121 of the swinging assembly 12, which can strengthen the structural strength of the driving mechanism 10, and thus is beneficial to improving the running stability of the driving mechanism 10.

[0062] The technical solutions provided by the embodiments of the present application will be described below in combination with specific application scenarios.

The output end 121 of the swinging component 12 sequentially passes through the transmission hole 141, the first track groove 131 and the second track groove 151. During the process of the driving component 11 driving the swinging component 12 to swing around the first preset axis, the output end 121 of the swinging component 12 moves along the second track groove 151, and at the same time, the output end 121 of the swinging component 12 synchronously drives the first baffle 13 to rotate around the second preset axis and synchronously drives the second baffle 14 to rotate around the first preset axis.

[0066] The rotation centers of the swinging component 12 and the first baffle 13 are not concentric to facilitate the arrangement of the driving mechanism 10 in the cleaning device; and, the first track groove 131 of the first baffle 13 extends in a direction close to the second preset axis to avoid jamming due to movement interference between the swinging component 12 and the first baffle 13; in addition, the second baffle 14 shields the internal structure of the cleaning device exposed by the first track groove 131, solving the problem of leakage shielding caused by the first track groove 131 of the first baffle 13 adopting a kidney-shaped groove design.

[0067] Application scenario two:

[0068] The driving mechanism 10 is applied to a cleaning device. The driving mechanism 10 includes a driving component 11. The driving mechanism 10 further includes a swinging component 12, and the swinging component 12 is in transmission connection with the driving component 11. The driving component 11 is used to drive the swinging component 12 to swing around a first preset axis, wherein the swinging component 12 has an output end 121. The cleaning component of the cleaning device is in transmission connection with the output end 121 of the swinging component 12, and the swinging component 12 drives the cleaning component to perform cleaning work through its output end 121. When the cleaning device needs to clean the corner area of the surface to be cleaned, the driving mechanism 10 drives the cleaning component to swing outwards relative to the device body of the cleaning device towards the outside of the cleaning device, and when the cleaning device does not need to clean the corner area of the surface to be cleaned, the driving mechanism 10 drives the cleaning component to swing inwards relative to the device body towards the inside of the cleaning device.

[0069] The driving mechanism 10 further includes a substrate 15, a first baffle 13 and a second baffle 14. The substrate 15 and the device body are fixed to each other. The first baffle 13 is configured to be able to rotate relative to the substrate 15 around a second preset axis. The first baffle 13 is provided with a first track groove 131, and the first track groove 131 extends towards the second preset axis. The substrate 15 is provided with a second track groove 151, and the second track groove 151 extends along the circumferential direction of the first preset axis. The second baffle 14 is provided with a transmission hole 141. The output end 121 of the swinging component 12 sequentially passes through the transmission hole 141, the first track groove 131 and the second track groove 151. During the process that the driving component 11 drives the swinging component 12 to swing around the first preset axis, the output end 121 of the swinging component 12 moves along the second track groove 151, and at the same time, the output end 121 of the swinging component 12 synchronously drives the first baffle 13 to rotate around the second preset axis and synchronously drives the second baffle 14 to rotate around the first preset axis.

[0070] The rotation center of the swinging component 12 is not concentric with the rotation center of the first baffle 13 to facilitate the arrangement of the driving mechanism 10 in the cleaning device; and, the first track groove 131 of the first baffle 13 extends in a direction close to the second preset axis to avoid jamming due to movement interference between the swinging component 12 and the first baffle 13; in addition, the second baffle 14 shields the internal structure of the cleaning device exposed by the first track groove 131, solving the problem of incomplete shielding caused by the waist-shaped groove design of the first track groove 131 of the first baffle 13.
