[0003] At present, sweeping robots are usually equipped with side sweeping components, which can sweep dust and fine garbage in many blind spots and have high cleaning efficiency. When working, the side sweeping components are driven by a motor to rotate. However, the existing side sweeping components include multiple side sweeps, and the relative positions between the multiple side sweeps and the body of the sweeping robot are fixed. When the sweeping robot performs cleaning operations, the motion trajectories of each side sweep when rotating are the same. In this way, not only the sweeping range of the sweeping robot is reduced, but also when hair is entangled on one of the side sweeps, the hair will come into contact with other side sweeps, causing the hair to be entangled on the side sweep all the time, affecting the cleaning effect of the side sweep.

[0031] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0034] As mentioned in the background technology, the existing side sweep assembly includes multiple side sweeps, and the relative positions between the multiple side sweeps and the body of the sweeping robot are fixed. During the rotation of the side sweep assembly, the movement trajectories of the side sweeps are the same, which not only reduces the cleaning range of the sweeping robot, but also when hair is entangled on one of the side sweeps, the hair will come into contact with other side sweeps, causing the hair to be entangled on the side sweep all the time, making it difficult to ensure the cleaning effect of the side sweep assembly. To this end, the present application provides a new side sweep assembly, which can solve the problem of the side sweep of the sweeping robot in the prior art being easily entangled with hair. The side sweep assembly of the present application will be described in detail below in conjunction with the accompanying drawings.

[0035] It should be noted that the "thickness direction of the main body" in this application refers to the thickness direction of the attached Figure 4 The direction indicated by the letter X in the figure; the “geometric center of the main body” in this application refers to the geometric center of the projection surface of the main body within the projection along the thickness direction of the main body; the “the distances from the second end of each cleaning arm to the eccentric axis are different” in this application refers to the distances from the second end of each cleaning arm to the eccentric axis are different within the projection along the thickness direction of the main body.

[0036] See also Figures 1 to 6 As shown, the present application provides a side-sweeping assembly, which includes a main body 10 , a connecting arm 30 and a cleaning arm 40 .

[0037] Among them, an eccentric shaft 20 is arranged on the main body 10, and the eccentric shaft 20 is arranged to deviate from the geometric center of the main body 10, and the main body 10 is configured to rotate eccentrically around the eccentric shaft 20; the connecting arm 30 includes a plurality of connecting arms 30, and the plurality of connecting arms 30 are arranged at intervals on the main body 10, and the first end of the connecting arm 30 is connected to the outer edge of the main body 10, and the second end of the connecting arm 30 extends in a direction away from the main body 10; the cleaning arm 40 includes a plurality of cleaning arms 40, and the plurality of cleaning arms 40 are arranged one-to-one with the plurality of connecting arms 30, and the first end of the cleaning arm 40 is connected to the second end of the connecting arm 30.

[0038] In this embodiment, when the side sweeping assembly is actually used, the side sweeping assembly can be installed on a cleaning device (such as a sweeping robot or a cleaning base station, etc.), and the rotating shaft of the motor on the cleaning device is connected to the eccentric shaft 20 on the main body 10 to drive the eccentric shaft 20 to rotate, thereby driving the main body 10 to rotate eccentrically around the eccentric shaft 20 with the eccentric shaft 20 as the center, and then the connecting arm 30 and the cleaning arm 40 can be driven to rotate synchronously. The cleaning arm 40 can clean dust and fine garbage in the dead corners in the space. During this process, since a connecting arm 30 is provided between the cleaning arm 40 and the main body 10 in this embodiment, when hair is entangled on the cleaning arm 40, the provision of the connecting arm 30 can extend the distance between the cleaning arm 40 and the main body 10, thereby preventing the hair on the cleaning arm 40 from directly contacting the main body 10 and being entangled on the main body 10 and the rotating shaft of the motor; at the same time, since the eccentric shaft 20 in this embodiment is set away from the geometric center of the main body 10, the distance from the second end of each cleaning arm 40 to the eccentric shaft 20 is different. In this way, when the main body 10 rotates eccentrically around the eccentric shaft 20, each cleaning arm 40 will form a different circular motion trajectory. During this process, when hair is entangled on one of the cleaning arms 40, the cleaning ranges of the cleaning arms 40 with different circular motion trajectories will not overlap, thereby preventing the hair on the cleaning arm 40 from contacting other cleaning arms 40, thereby preventing the hair from being entangled on the cleaning arm 40 all the time, and effectively ensuring the cleaning effect of the side sweeping assembly.

[0039] That is, in this embodiment, by arranging the eccentric shaft 20 on the main body 10 and making the eccentric shaft 20 deviate from the geometric center of the main body 10, the cleaning arm 40 can form different circular motion trajectories during the rotation process, effectively preventing the hair on each cleaning arm 40 from being entangled with another cleaning arm 40, thereby preventing the hair from remaining for a long time, and effectively ensuring the cleaning effect of the side sweeping assembly. Compared with the side sweeping assembly in the prior art, the cleaning arm 40 of the side sweeping assembly in this embodiment is not easily entangled by hair, which can improve the cleaning effect of the side sweeping assembly.

[0040] Optionally, the connecting arm 30 and the cleaning arm 40 in the present application may include two, three, four or more than four, which is not specifically limited in the present application and can be designed according to actual processing requirements. Figure 1 The diagram shows a case where there are three connecting arms 30 and three cleaning arms 40 .

[0041] Further, see Figure 3As shown, the eccentric shaft 20 in this embodiment has an eccentricity e, and the eccentricity e is greater than or equal to 1 mm and less than or equal to 6 mm. That is to say, the eccentricity e in this embodiment satisfies the relationship: 1mm≤e≤6mm, for example, e can be 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm and any value therebetween. When the eccentricity e is less than 1mm, the distance between the eccentric shaft 20 and the geometric center of the main body 10 will be shortened, so that the distance from the second end of each cleaning arm 40 to the eccentric shaft 20 tends to be the same, resulting in each cleaning arm 40 forming the same circular motion trajectory, so that the cleaning range of each cleaning arm 40 overlaps, and hair is easily entangled on each cleaning arm 40; when the eccentricity e is greater than 6mm, during the rotation of the side sweeping assembly, a large centrifugal force will be generated, thereby increasing the vibration and deformation of the side sweeping assembly and reducing the overall stability of the side sweeping assembly. That is to say, in this embodiment, by making the eccentric distance e satisfy the relationship: 1mm≤e≤6mm, it is possible to not only ensure the cleaning effect of the side sweeping assembly, but also prevent hair from being entangled on each cleaning arm 40.

[0042] Further, see Figure 2 as well as Figure 5 As shown, in the projection along the thickness direction of the main body 10, the projection of the main body 10 in this embodiment includes a circle, and the extension direction of the connecting arm 30 is the same as the radial direction of the circle. Such a configuration is conducive to improving the overall stability of the side sweeping assembly, and when the cleaning arm 40 is connected to the connecting arm 30, the cleaning arm 40 can fit with the edge of the space, so that the cleaning arm 40 can more smoothly clean the dust and fine garbage in the dead corner area. Of course, in other embodiments of the present application, the projection of the main body 10 also includes a rectangular, square or other special-shaped structures. As long as it is other deformation methods under the conception of the present application, they are all within the protection scope of the present application.

[0043] Further, see Figure 1 to Figure 2 As shown, the cleaning arm 40 in this embodiment extends along the length direction of the connecting arm 30. That is to say, the extension direction of the cleaning arm 40 in this embodiment is consistent with that of the connecting arm 30, so that when the side sweeping assembly is cleaning hard-to-reach areas such as corners or furniture edges, the cleaning arm 40 can preferentially contact the hard-to-reach areas compared to the connecting arm 30, which can not only sweep dust and dirt into the cleaning range of the side sweeping assembly, thereby improving the cleaning efficiency of the cleaning device, but also prevent the connecting arm 30 from colliding with furniture or walls, thereby preventing the connecting arm 30 from being damaged, thereby extending the service life of the side sweeping assembly.

[0044] Further, see Figure 1As shown, the connecting arms 30 and the cleaning arms 40 in this embodiment each include three, each cleaning arm 40 extends along the length direction of each connecting arm 30, and in the projection along the thickness direction of the main body 10, the distance from the second end of each cleaning arm 40 to the geometric center of the main body 10 is the same. That is to say, the three cleaning arms 40 in this embodiment have the same length. Since the eccentric shaft 20 is set away from the geometric center of the main body 10, the distance from the second end of each cleaning arm 40 to the eccentric shaft 20 is different, so that each cleaning arm 40 forms a different circular motion trajectory to clean dust and fine garbage in different cleaning areas, which increases the cleaning area of ​​the side sweeping assembly to a certain extent, improves the cleaning effect of the side sweeping assembly, and can prevent the hair on each cleaning arm 40 from coming into contact with other cleaning arms 40, thereby preventing the hair from being entangled on the cleaning arm 40, effectively ensuring the cleaning effect of the side sweeping assembly.

[0045] Further, see Figure 4 As shown, the cleaning arm 40 and the main body 10 in this embodiment are located on a first plane (with Figure 4 The first angle A is greater than 59° and less than 61°. In other words, the first angle A in this embodiment satisfies the relationship: 59°<A<61°, such as 59.2°, 59.4°, 59.6°, 59.8°, 60°, 60.2°, 60.4°, 60.6°, 60.8° and any value therebetween. When the first angle A is less than 59°, the cleaning arm 40 will leave the ground to be cleaned during the rotation of the side sweeping assembly, making it difficult to ensure that the cleaning arm 40 always keeps in contact with the ground to be cleaned, thereby failing to clean the dust and fine garbage on the ground to be cleaned; when the first angle A is greater than 61°, although the cleaning arm 40 can always keep in contact with the ground to be cleaned, due to the excessively large angle, it is easy to cause the second end of the cleaning arm 40 to tilt away from the ground to be cleaned, and when the side sweeping assembly rotates, the friction between the second end of the cleaning arm 40 and the ground to be cleaned is increased, causing the cleaning arm 40 to be worn, thereby affecting the service life of the cleaning arm 40. That is to say, by making the first angle A satisfy the relationship: 59°<A<61°, this embodiment can not only ensure that the cleaning arm 40 always keeps in contact with the ground to be cleaned, effectively improving the cleaning effect of the side sweeping assembly, but also prevent the cleaning arm 40 from being worn due to excessive friction, thereby extending the service life of the cleaning arm 40.

[0046] Specifically, the first angle A between the cleaning arm 40 and the first plane where the main body 10 is located in this embodiment is preferably 60°.

[0047] Furthermore, the cleaning arm 40 in the present embodiment comprises a nylon arm. Nylon has the advantages of high strength, good wear resistance, and easy cleaning. In the present embodiment, the nylon arm is set as the cleaning arm 40, so that the cleaning arm 40 can be subjected to greater friction, which is convenient for cleaning dust and dirt in the corners of the space, and can improve the structural strength of the cleaning arm 40 to prevent the cleaning arm 40 from being worn during use. Of course, in other embodiments of the present application, the cleaning arm 40 can also be a rubber arm or a plastic arm, and the rubber arm or the plastic arm has an anti-static effect, which can prevent the cleaning arm 40 from rubbing against the hair and generating static electricity to adsorb the hair on the cleaning arm 40.

[0048] Furthermore, the cleaning arm 40 in this embodiment includes a plurality of bristles, the first ends of the plurality of bristles are connected to the connecting arm 30, and the second ends of the plurality of bristles are fixedly connected as a whole. That is to say, the end of the second end of the bristles in this embodiment is an integral structure, and such a configuration can prevent the plurality of bristles in the cleaning arm 40 from opening when contacting the ground, thereby preventing the plurality of opened bristles from merging to pick up hair when the cleaning arm 40 leaves the ground, effectively preventing the hair from being entangled on the cleaning arm 40, and ensuring the cleaning effect of the side sweeping assembly.

[0049] Furthermore, the second ends of the multiple bristles in this embodiment are fixedly connected as one body by the tightening rubber sleeve 50. This arrangement can prevent the bristles from merging and picking up hairs when the cleaning arm 40 opens and contacts the ground and leaves the ground. Of course, in other embodiments of the present application, the second ends of the multiple bristles can be bonded together using adhesives such as glue to form an integral structure.

[0050] Furthermore, in order to improve the structural strength and service life of the side sweep assembly in this embodiment, the connecting arm 30 and the main body 10 in this embodiment are processed by integral injection molding, and the structure is stable and reliable. Of course, in other embodiments of the present application, the connecting arm 30 and the main body 10 can also be connected by screw connection, welding or clamping, etc. As long as it is other deformation methods under the conception of this application, it is within the protection scope of this application.

[0051] Further, see Figure 2 As shown, the multiple connecting arms 30 in this embodiment are evenly spaced along the circumference of the main body 10 on the outer edge of the main body 10, and the second end of each connecting arm 30 is connected to the first end of the cleaning arm 40. Such a configuration can improve the uniformity of cleaning of the side sweeping assembly, and the user experience is good. Of course, in other embodiments of the present application, the multiple connecting arms 30 can be unevenly spaced along the circumference of the main body 10 on the outer edge of the main body 10, as long as it is other deformation methods under the conception of the present application, they are all within the protection scope of the present application.

[0052] Furthermore, the first end of the cleaning arm 40 in this embodiment is bonded to the second end of the connecting arm 30. That is to say, the cleaning arm 40 in this embodiment is bonded to the connecting arm 30 by an adhesive such as glue, and has a simple structure and is easy to process. Of course, in other embodiments of the present application, the cleaning arm 40 and the connecting arm 30 can also be connected by clamping, welding, screwing or integral injection molding.

[0053] In combination with the above-mentioned embodiments, it can be known that the present application sets the eccentric shaft on the main body and sets the eccentric shaft away from the geometric center of the main body. In this way, the cleaning arm can form different circular motion trajectories during the rotation process, which can not only clean the dust and small garbage in different cleaning areas and increase the cleaning area of ​​the side sweeping component, but also prevent the hair on each cleaning arm from being entangled with another cleaning arm, thereby avoiding the long-term residual hair and effectively ensuring the cleaning effect of the side sweeping component.

[0054] On the other hand, the embodiment of the present application further provides a cleaning device, which can be, for example, a sweeping robot, or a cleaning base station, etc. The cleaning device includes the above-mentioned side sweeping component, and therefore, the cleaning device includes all the technical effects of the above-mentioned side sweeping component. Since the technical effects of the side sweeping component have been described in detail above, they will not be repeated here.

[0055] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0056] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0057] The above are only preferred embodiments of the present application and are 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.
