[0030] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0031] Please refer to Figures 1 to 4 The present embodiment provides a cleaning robot 10, which comprises a bottom shell 100 and an edge brush device 200, and the edge brush device 200 is installed on the bottom shell 100. The edge brush device 200 comprises a brush arm assembly 220 and a driving assembly 210, and the driving assembly 210 is used to drive the brush arm assembly 220 to rotate around the rotation axis of the edge brush device 200 in a first direction or a second direction, and the first direction is opposite to the second direction, and the first direction and the second direction can be clockwise or counterclockwise in general.

[0032] The bottom shell 100 of the cleaning robot 10 provided in the present embodiment is provided with a guide piece 110 protruding from the bottom shell 100, please refer to Figures 4 to 7The first side (a) of the guide plate 110 is at its minimum distance from the bottom shell 100 (it may not contact the bottom shell; in some cases, the first side (a) of the guide plate 110 may contact the bottom shell). The second side (b) of the guide plate 110 protrudes from the bottom shell 100 and is at its maximum distance from the bottom shell 100. This results in the guide plate 110 and the bottom shell 100 being non-parallel, meaning that the surface of the guide plate 110 and the surface of the bottom shell 100 are two intersecting surfaces. The guide plate 110 is inclined to the bottom shell 100 and forms a receiving cavity with the bottom shell 100. This receiving cavity is used to receive the brush arm assembly 220 on the side brush device 200. It can be understood that the distance from the first side of the guide plate to the cleaning surface is less than the distance from the second side of the guide plate to the cleaning surface. The guide plate 110 is inclined to the bottom shell 100, and the second side of the guide plate is higher than the first side. The first side of the guide plate may contact the bottom shell, or the first side of the guide plate may be at a certain distance from the bottom shell, and the second side is higher than the first side, causing the guide plate to be inclined to the bottom shell.

[0033] Please see Figures 4 to 7 When the brush arm assembly 220 rotates along the first direction (clockwise), the brush arm assembly 220 can turn from the first side (a) of the guide plate 110 to the second side (b). At this time, the brush arm assembly 220 will not enter the receiving cavity formed by the guide plate 110 and the bottom shell 100, but can normally act on the cleaning surface. When the brush arm assembly 220 rotates along the second direction (counterclockwise), the brush arm assembly 220 on the side brush device 200 turns from the second side (b) of the guide plate 110 to the first side (a) of the guide plate 110. Since the first side (b) of the guide plate 110 protrudes from the bottom shell 100, the brush arm assembly will enter the receiving cavity formed by the guide plate 110 and the bottom shell 100. At this time, the drive assembly 210 stops rotating, and the brush arm assembly 220 will be at least partially received in the receiving cavity, thereby realizing the hiding of the side brush and avoiding contact between the side brush and the cleaning surface, which would affect the cleaning effect of the cleaning robot 10. Of course, the part on the brush arm assembly 220 here can be a brush, or a brush and part of the brush gel can be contained in the receiving cavity.

[0034] Assuming H1 represents the height of the bottom shell, H2 represents the vertical height of the brush colloid and the lowest point of the guide plate, H3 represents the height of the lowest point inside the guide plate, and H4 represents the height of the lowest point outside the guide plate, then the following condition is satisfied: H1 > H2 > H3 > H4 > 0.

[0035] Please see Figures 1 to 3In some other examples, the bottom shell 100 of the cleaning robot 10 has an opening through which access can be made to the other side of the bottom shell (the inside of the cleaning robot main unit). The guide plate 110 protrudes from the bottom shell 100 and covers at least a portion of the opening of the bottom shell 100. At this time, the lowest side of the guide plate 110 protrudes from the bottom shell 100, and the highest side of the guide plate 110 is in contact with the bottom shell 100 and integrally formed with the bottom shell 100. The lowest side of the guide plate 110 and the opening on the bottom shell 100 form a receiving cavity. Similarly, when the brush arm assembly 220 rotates along the first direction, it can turn from the highest side (the side connected to the bottom shell 100) of the guide plate 110 to the lowest side. At this time, the brush arm assembly 220 will not enter the receiving cavity formed by the guide plate 110 and the bottom shell 100, but can normally act on the cleaning surface. When the brush arm assembly 220 rotates along the second direction, the brush arm assembly 220 on the side brush device 200 turns from the lowest side to the highest side and will enter the opening (receiving cavity) of the guide plate 110. When the drive assembly 210 stops rotating, the brush arm assembly 220 will be at least partially received in the receiving cavity, thereby hiding the side brush and preventing the side brush from contacting the cleaning surface and affecting the cleaning effect of the cleaning robot 10.

[0036] Of course, to prevent the brush arm assembly 220 from carrying dirt into the inside of the main unit, dirt blocking or filtering components can be installed at the opening on the inside of the main unit.

[0037] Figures 1 to 3 The guide plate shown is integrally molded with the bottom shell of the cleaning robot. Figures 4 to 7 The guide plate shown is not integrally formed with the bottom shell of the cleaning robot. For guide plates that are not integrally formed with the bottom shell, the first side of the guide plate 110 can be fixed to the bottom shell 100 by screws or by adhesive. It is also understood that the shape of the guide plate, in addition to... Figures 4 to 7 The fan shape shown can also be triangular, circular, rectangular, or other shapes, as well as a hollow structure of the aforementioned shapes. In addition, the guide plate can also be "L" shaped, with the two ends of the "L" fixed to the bottom shell respectively. The right angle position of the "L" is the farthest point from the bottom shell, which is the lowest point, and forms a receiving cavity with the bottom shell.

[0038] It is understood that the brush arm assembly 220 on the side brush device 200 includes a brush colloid 221 and a brush 222, with the lowest point of the brush colloid 221 being higher than the lowest point (lowest side) of the guide plate 110. (See [link to documentation]). Figures 1 to 3When the brush arm assembly 220 rotates in the second direction (counterclockwise), the brush 222 interferes with the raised guide plate 110 and is at least partially housed in the receiving cavity, thus hiding the side brush and preventing it from contacting the cleaning surface and affecting the cleaning effect of the cleaning robot 10. Specifically, the interference between the brush 222 and the raised guide plate 110 means that the brush 222 or the brush gel 221 deforms upon contact with the guide plate 110 and enters the receiving cavity.

[0039] To detect whether the brush arm assembly 220 on the side brush device 200 has entered the receiving cavity, the cleaning robot 10 in this embodiment also includes a Hall element 310 and a sensing magnet 320. (See attached image.) Figure 3 The side brush device 200 also includes a side brush housing 230, with a brush arm assembly 220 disposed within the side brush housing 230. A Hall element 310 from the cleaning machine is located on the bottom shell 100 near the side brush housing 230. A sensing magnet 320(a) is positioned on the side brush housing 230. After the brush arm assembly 220 stops rotating, the position of the brush arm assembly 220 and whether it has entered the receiving cavity can be determined by whether the sensing magnet 320(a) on the side brush housing 230 is aligned with the Hall element 310 on the bottom shell 100 (generating a detection signal). In other examples, the brush arm assembly 220 includes a brush body 221 and a brush 222. A sensing magnet 320(b) is embedded in the brush body 221. Similarly, the position of the brush arm assembly 220 and whether it has entered the receiving cavity can be determined by whether the 320(b) on the brush body 221 is aligned with the Hall element 310 on the bottom shell 100 (generating a detection signal). certainly, Figure 3 The structures in which the sensing magnet 320(a) is disposed on the side brush housing 230 and the sensing magnet 320(b) is embedded in the brush colloid 221 are shown. In other examples, the sensing magnet 320 may be disposed only on the side brush housing 230 or embedded only in the brush colloid 221.

[0040] Please see Figure 7 In some examples, the side of the guide plate 110 facing the receiving cavity has comb teeth that can clean debris from the brush 222. In other examples, such as Figure 6 The guide plate 110 has a hollow structure, which effectively reduces the amount of debris remaining in the guide groove. Of course, when the guide plate 110 has a hollow structure, the side facing the receiving cavity also has comb teeth.

[0041] Please see Figures 5 to 7This utility model embodiment also provides a cleaning robot 10, which includes a side brush device 200 mounted on a base shell 100. The side brush device 200 includes a drive assembly 210 and a brush arm assembly 220. The drive assembly 210 is used to drive the brush arm assembly 220 to rotate around the rotation axis of the side brush device 200 and to stop the brush arm assembly 220 from rotating around the rotation axis of the side brush device 200. In addition, the base shell 100 of the cleaning robot 10 has a guide plate 110, which forms a receiving channel with the base shell 100. When the brush arm assembly 220 of the cleaning robot 10 rotates, the brush arm assembly 220 can act on the cleaning surface through the receiving channel formed by the guide plate 110 and the base shell 100. At this time, the brush arm assembly 220 can work normally, and the guide plate 110 does not affect the operation of the brush arm assembly 220. After the brush arm assembly 220 stops rotating, the brush arm assembly 220 can be received in the receiving channel formed by the guide plate 110 and the base shell 100.

[0042] The difference between a receiving cavity and a receiving channel lies in whether the brush arm assembly, after entering the receiving position (receiving cavity or receiving channel) along a first direction, can continue to rotate out of the receiving position along the first direction. Understandably, if it is a receiving cavity, the brush arm assembly cannot continue to rotate out of the receiving cavity along the first direction after entering; if it is a receiving channel, the brush arm assembly can rotate out of the receiving channel after entering along the first direction and continuing to rotate along the first direction.

[0043] In some examples, the guide plate 110 has comb teeth on the side facing the receiving channel, which can clean debris from the brush 222. In other examples, the guide plate 110 has a hollow structure, which can effectively reduce the amount of debris remaining in the guide groove. Of course, if the guide plate 110 can be a hollow structure, it also has comb teeth on the side facing the receiving channel.

[0044] Besides the shape of the guide plate Figures 4 to 7 The fan shape shown can also be triangular, circular, rectangular, or other shapes, as well as a hollow structure of the aforementioned shapes. In addition, the guide plate can also be "L" shaped, with the two ends of the "L" fixed to the bottom shell respectively. The right angle position of the "L" is the farthest point from the bottom shell, which is the lowest point, and forms a receiving channel with the bottom shell.

[0045] To detect whether the brush arm assembly 220 on the side brush device 200 has entered the receiving channel, the cleaning robot 10 in this embodiment also includes a Hall element 310 and a sensing magnet 320. The side brush device 200 also includes a side brush housing 230, and the brush arm assembly 220 is disposed in the side brush housing 230. The Hall element 310 on the cleaning robot is located on the bottom shell 100 near the side brush housing 230. At this time, the sensing magnet 320 is located on the side brush housing 230. After the brush arm assembly 220 stops rotating, the position of the brush arm assembly 220 and whether the brush arm assembly 220 has entered the receiving channel can be determined by whether the sensing magnet 320 on the side brush housing 230 is opposite to the Hall element 310 on the bottom shell 100 (generating a detection signal). In some other examples, the brush arm assembly 220 includes a brush body 221 and a brush 222, with a sensing magnet 320 embedded in the brush body 221. Similarly, the position of the brush arm assembly 220 and whether the brush arm assembly 220 has entered the receiving channel can be determined by whether the sensing magnet 320 on the brush body 221 is opposite to the Hall element 310 on the bottom shell 100 (generating a detection signal).

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
