Technical Field
[0001] This application relates to the field of cleaning equipment technology, specifically to a side brush mechanism and cleaning equipment. Background Technology
[0002] In related technologies, a side brush mechanism is usually set on the main body of the cleaning equipment. The swing arm of the side brush mechanism is rotatably set on the main body and carries the side brush body. The swing arm extends outward to expand the cleaning range of the side brush mechanism. However, when the swing arm comes into contact with an obstacle, it is easy to get stuck, which affects the cleaning efficiency and cleaning effect of the cleaning equipment. Therefore, how to reduce the risk of the side brush mechanism getting stuck in order to improve the cleaning efficiency and cleaning effect of the cleaning equipment is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0004] To solve the above-mentioned technical problems, the technical solution adopted in this application is conceived as follows:
[0005] In a first aspect, this application provides a side brush mechanism for a cleaning device. The cleaning device includes a main body and a side brush mechanism. The side brush mechanism includes: a swing arm for being disposed on the main body and rotatable relative to the main body; a side brush body disposed at one end of the swing arm; and an anti-collision component that is rollably connected to one end of the swing arm and protrudes at least outside the front contour of the swing arm.
[0006] In some embodiments, one end of the swing arm is provided with two mounting seats, which are spaced apart along a first direction; the anti-collision assembly includes: a fixed shaft connecting the two mounting seats and at least partially located between the two mounting seats; a rolling element located between the two mounting seats and sleeved outside the fixed shaft, which can rotate around the fixed shaft; wherein, the first direction is parallel to the arrangement direction of the top and bottom of the main body.
[0007] In some embodiments, the mounting base is provided with a mounting hole, the rolling element is provided with a through hole, and one end of the fixed shaft is provided with a fixing part; wherein, the other end of the fixed shaft passes through the mounting hole, the through hole and the mounting hole of another mounting base in sequence, and the fixing part is fixed in the mounting hole of one mounting base.
[0008] In some embodiments, the scroll member is positioned above the brush body along a first direction.
[0009] In some embodiments, along the first direction, the outer diameter of the rolling element gradually decreases from the middle toward both ends.
[0010] In some embodiments, the swing arm includes a first state and a second state. In the first state, one end of the swing arm is located at the bottom of the main body or inside the main body. In the second state, one end of the swing arm is at least partially located outside the side profile of the main body. One end of the swing arm is provided with a corner area, which is located on the front side of the swing arm along the rotation direction. An anti-collision component is provided in the corner area. In the rotation direction, the swing arm switches from the first state to the second state.
[0011] In some embodiments, the side brush mechanism further includes a drive assembly connected to the swing arm for driving the swing arm to switch between a first state and a second state; and / or, the side brush mechanism further includes an elastic element connected to the swing arm and / or the drive assembly, the elastic element being configured to deform when the swing arm is in the second state and interferes with an obstacle, so that one end of the swing arm moves toward the body; the elastic element is also configured to restore its deformation when the swing arm is no longer interfering with the obstacle, so as to drive one end of the swing arm to move away from the body.
[0012] In some embodiments, the maximum radial dimension of the rolling element is 2mm-12mm; the dimension of the rolling element along the first direction is 2mm-12mm.
[0013] In some embodiments, the side brush mechanism further includes a housing for fixing to the main body, and the housing has a first receiving groove, wherein the other end of the swing arm opposite to one end is rotatably disposed in the first receiving groove.
[0014] Secondly, this application provides a cleaning device, which includes a main body and the aforementioned side brush mechanism.
[0015] The beneficial effects of the embodiments of this application, which differ from the prior art, are as follows: This application provides a side brush mechanism and a cleaning device. The side brush mechanism is used for cleaning devices. The side brush mechanism includes a swing arm, a side brush body and an anti-collision component. The swing arm is disposed on the main body and can rotate relative to the main body. The side brush body is disposed at one end of the swing arm. The anti-collision component is rollably connected to one end of the swing arm and at least protrudes outside the front contour of the swing arm. By rolling the anti-collision component to one end of the swing arm, and ensuring that the anti-collision component protrudes at least beyond the front contour of the swing arm, the anti-collision component contacts the obstacle first relative to the swing arm during the operation of the side brush mechanism. Furthermore, the anti-collision component can roll into contact with the obstacle. On one hand, this allows the cleaning equipment to navigate around the obstacle's contour via the anti-collision component, assisting in turning or adjusting its position. This reduces the risk of jamming in the side brush mechanism, enabling the cleaning equipment to quickly overcome obstacles and continue cleaning operations, effectively improving cleaning efficiency and effectiveness. On the other hand, it reduces the risk of direct friction or collision between the swing arm and the obstacle, thereby reducing the impact force between the side brush mechanism and the obstacle. This further reduces the risk of wear or cracking in the side brush mechanism, extending its service life. Attached Figure Description

[0031] Please refer to Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of an embodiment of the cleaning equipment provided in this application; Figure 2 yes Figure 1 Enlarged view of part A in the image; Figure 3 yes Figure 1 The image shows a bottom view of the cleaning device. This application provides a side brush mechanism 100 for use in a cleaning device 1000. The cleaning device 1000 includes a main body 200 and a side brush mechanism 100. The cleaning device 1000 can be a sweeping robot, a sweeping and mopping robot, a carpet cleaner, a pool cleaning robot, etc., but is not limited to these. The main body 200 can serve as the basic carrier of the cleaning device 1000. The main body 200 can be a one-piece structure or a combined structure formed by the cooperation of multiple parts. The side brush mechanism 100 is rotatably disposed at the bottom of the main body 200 and located in the front corner area of the cleaning device 1000 along the forward direction. The cleaning device 1000 may include one side brush mechanism 100, which is disposed in a corner area of the front side of the cleaning device 1000 along the forward direction; or the cleaning device 1000 may include two side brush mechanisms 100, which are respectively disposed in the corner areas of opposite sides of the front side of the cleaning device 1000 along the forward direction.
[0032] In some embodiments, a suction port 200a is provided at the bottom of the main body 200, and the suction port 200a communicates with a collection assembly (not shown) disposed within the main body 200. A suction assembly (not shown) is provided at the suction port 200a or within the collection assembly, and the suction assembly is used to drive the object to be cleaned from the suction port 200a into the collection assembly. The suction port 200a has a working area, which is the radiation area in which the suction force generated by the suction assembly at the suction port 200a or within the collection assembly can produce cleaning effectiveness. The side brush mechanism 100 is used to guide the object to be cleaned from the area to be cleaned to the working area of the suction port 200a, so that the object to be cleaned can be sucked into the collection assembly disposed within the main body 200 by the suction assembly.
[0033] The side brush mechanism 100 includes a swing arm 10, a side brush body 20, and a collision avoidance component 30. The swing arm 10 is mounted on the main body 200 and is rotatable relative to the main body 200. The side brush body 20 is located at one end of the swing arm 10. The collision avoidance component 30 is slidably connected to one end of the swing arm 10 and protrudes at least beyond the front contour of the swing arm 10.
[0034] The side brush body 20 is located at one end of the swing arm 10, and the other end of the swing arm 10 is rotatably located on the main body 200, either directly or indirectly.
[0035] Please continue to refer to Figures 1 to 3 At the same time, refer to Figure 4 , Figure 4This is a bottom view of another embodiment of the cleaning device provided in this application. The swing arm 10 includes a first state and a second state. In the first state, one end of the swing arm 10 is located at the bottom of the main body 200 or inside the main body 200, such as... Figure 4 As shown. In the second state, at least one end of the swing arm 10 is located outside the side profile of the body 200, as... Figures 1 to 3 As shown. In the first state, the swing arm 10 is in an inward-retracted state, at which time the anti-collision component 30 is closest to the main body 200; in the second state, the swing arm 10 is in an extended state, and in the second state, one end of the swing arm 10 is located at the position furthest from the main body 200. The anti-collision component 30 is located on the front side of the swing arm 10 in the rotation direction from the first state to the second state, so that the anti-collision component 30 at least protrudes outside the front contour of the swing arm 10.
[0036] When the swing arm 10 is in the second state, the anti-collision component 30 may extend beyond the side profile of the main body 200. It is understood that the orthographic projection of the anti-collision component 30 toward the travel surface of the cleaning device 1000 is not only outside the front boundary profile of the orthographic projection of the swing arm 10 toward the travel surface of the cleaning device 1000, but also, when the swing arm 10 is in the second state, the orthographic projection of the anti-collision component 30 toward the travel surface of the cleaning device 1000 is outside the side boundary profile of the orthographic projection of the main body 200 toward the travel surface of the cleaning device 1000.
[0037] When the swing arm 10 is in the second state, the side brush body 20 is at least partially located outside the side contour of the main body 200. It is understood that when the swing arm 10 is in the second state, the orthographic projection of the side brush body 20 toward the travel surface of the cleaning device 1000 is at least partially located outside the side boundary contour of the orthographic projection of the main body 200 toward the travel surface of the cleaning device 1000. This expands the cleaning range of the side brush body 20, allowing it to guide objects to be cleaned outside the working area of the suction port 200a to the working area of the suction port 200a, thereby improving the cleaning effect of the cleaning device 1000.
[0038] By rollingly connecting the anti-collision component 30 to one end of the swing arm 10, and ensuring that the anti-collision component 30 protrudes at least beyond the front contour of the swing arm 10, the anti-collision component 30 contacts the obstacle first relative to the swing arm 10 during the operation of the side brush mechanism 100. Furthermore, the anti-collision component 30 can roll into contact with the obstacle. On one hand, this allows the cleaning equipment 1000 to navigate around the obstacle's contour via the anti-collision component 30, helping it to turn or adjust its position. This reduces the risk of the side brush mechanism 100 getting stuck, allowing it to quickly overcome the obstacle and continue cleaning operations, effectively improving its cleaning efficiency and effectiveness. On the other hand, it reduces the risk of the swing arm 10 directly rubbing or colliding with the obstacle, thus reducing the impact force between the side brush mechanism 100 and the obstacle. This further reduces the risk of wear or cracking of the side brush mechanism 100, extending its service life.
[0039] Please refer to the above as well. Figures 5 to 6 , Figure 5 This is a schematic diagram of the structure of an embodiment of the edge brush mechanism provided in this application; Figure 6 yes Figure 5 The diagram shows an exploded view of the side brush mechanism. In some embodiments, one end of the swing arm 10 is provided with two mounting seats 11, which are spaced apart along a first direction ZZ. The anti-collision assembly 30 includes a fixed shaft 31 and a rolling element 32. The fixed shaft 31 connects the two mounting seats 11 and is at least partially located between the two mounting seats 11. The rolling element 32 is located between the two mounting seats 11 and is sleeved outside the fixed shaft 31. The rolling element 32 can rotate around the circumference of the fixed shaft 31. The first direction ZZ is parallel to the arrangement direction of the top and bottom of the main body 200.
[0040] The mounting base 11 can be integrally formed on the swing arm 10; or, the mounting base 11 can be fixedly connected to the swing arm 10. The fixed connection method of the mounting base 11 to the swing arm 10 can be welding, riveting, bolting, screwing, pin connection or snap-fit connection, etc., but is not limited to these.
[0041] Two mounting bases 11 can be spaced apart along the top and bottom arrangement directions of the main body 200. At this time, the fixed shaft 31 extends along the top and bottom arrangement directions of the main body 200, and the axial direction of the rolling element 32 is parallel to the top and bottom arrangement directions of the main body 200, so that the rolling element 32 can roll in the horizontal direction. This allows the rolling element 32 to roll in the horizontal direction when it collides with an obstacle, reducing the risk of hard interference of the side brush mechanism 100 and thus improving the obstacle avoidance capability of the cleaning equipment 1000.
[0042] In some embodiments, the two mounting bases 11 may also be spaced apart along a direction that intersects the arrangement direction of the top and bottom of the main body 200, so that the extension direction of the fixed shaft 31 intersects the arrangement direction of the top and bottom.
[0043] In some embodiments, the rolling element 32 is elastic and can absorb collision energy when it collides with an obstacle. This not only reduces the risk of wear, cracking or deformation of the side brush mechanism 100 and the main body 200 due to collision, but also reduces collision noise.
[0044] In some embodiments, the material of the rolling element 32 may be silicone, rubber, thermoplastic elastomer (TPE) or thermoplastic polyurethane (TPU), but is not limited thereto; or the rolling element 32 may be a combination of silicone, rubber, thermoplastic elastomer or thermoplastic polyurethane and metal, wherein the silicone, rubber, thermoplastic elastomer or thermoplastic polyurethane, etc., are coated on the surface of the metal.
[0045] In some embodiments, please continue to refer to Figure 6 The mounting base 11 is provided with a mounting hole 11a, the rolling element 32 is provided with a through hole 32a, and one end of the fixed shaft 31 is provided with a fixing part 311. The other end of the fixed shaft 31 passes through the mounting hole 11a, the through hole 32a of one mounting base 11 and the mounting hole 11a of another mounting base 11 in sequence, and the fixing part 311 is fixed in the mounting hole 11a of one mounting base 11.
[0046] Both mounting bases 11 are provided with mounting holes 11a, and the mounting holes 11a of the two mounting bases 11 are correspondingly arranged. When the rolling element 32 is disposed between the two mounting bases 11, the mounting hole 11a of one mounting base 11, the through hole 32a of the rolling element 32, and the mounting hole 11a of the other mounting base 11 are coaxially arranged.
[0047] In some embodiments, a mounting base 11 may be located above another mounting base 11 along a first direction ZZ. The mounting hole 11a of one mounting base 11 is a through hole, and the mounting hole 11a of the other mounting base 11 is a blind hole, wherein the opening end of the blind hole faces the first mounting base 11. The other end of the fixed shaft 31 without a fixing part 311 passes sequentially through the mounting hole 11a of the first mounting base 11, the through hole 32a of the rolling element 32, and the mounting hole 11a of the other mounting base 11. The other end of the fixed shaft 31 without the fixing part 311 is fixed to the mounting hole 11a of another mounting base 11, and the end face of the other end of the fixed shaft 31 without the fixing part 311 can abut against the bottom wall of the mounting hole 11a of another mounting base 11. The fixing part 311 is fixedly connected to the mounting hole 11a of a mounting base 11, thereby improving the connection strength and stability of the fixed shaft 31, reducing the risk of the fixed shaft 31 loosening or separating from the mounting base 11, thereby reducing the risk of the rolling element 32 falling off.
[0048] Please refer to Figure 7 , Figure 7 This is a schematic diagram of the structure of the fixed shaft of the anti-collision component of the side brush mechanism provided in this application. The outer surface of the fixing part 311 is provided with knurling, and the fixing part 311 is embedded in the mounting hole 11a of a mounting base 11. The knurling is used for interference connection with the inner wall of the mounting hole 11a of the mounting base 11. The knurling is a knurled tooth structure arranged at intervals along the circumference of the fixing part 311, which can increase the roughness of the outer surface of the fixing part 311, thereby reducing the risk of the fixing part 311 loosening or detaching from the mounting hole 11a of the mounting base 11. Furthermore, the knurling can form a detachable connection with the inner wall of the mounting hole 11a of the mounting base 11, which facilitates the disassembly of the fixed shaft 31 to replace the rolling element 32 when it is damaged, without having to replace the entire side brush mechanism 100, thereby reducing the maintenance cost of the side brush mechanism 100. The method of disassembling the fixed shaft 31 can be axial pulling, ultrasonic vibration, cold shrinkage, etc., but is not limited to these.
[0049] In some embodiments, the outer surface of the fixing part 311 is provided with external threads, and the inner wall of the mounting hole 11a of the mounting base 11 is provided with internal threads, and the fixing part 311 and the mounting hole 11a are connected by threads.
[0050] In some embodiments, the mounting holes 11a of the two mounting bases 11 are through holes.
[0051] In some embodiments, the rolling element 32 is positioned above the side brush body 20 along the first direction ZZ, so that the rolling element 32 and the side brush body 20 do not interfere with each other, thereby improving the cleaning effect and reliability of the side brush mechanism 100.
[0052] Please refer to Figure 8, Figure 8 This is a cross-sectional view of an embodiment of the rolling element of the anti-collision component of the side brush mechanism provided in this application. In some embodiments, along the first direction ZZ, the outer diameter of the rolling element 32 gradually decreases from the middle toward both ends.
[0053] The rolling element 32 is annular along a cross-section perpendicular to the first direction ZZ. The outer diameter of the rolling element 32 gradually decreases from the middle towards both ends along the first direction ZZ, meaning that the outer diameter of the rolling element 32 is largest in the middle region along the first direction ZZ. This ensures that when the rolling element 32 contacts an obstacle, the middle region of the rolling element 32 contacts the obstacle preferentially, and it also restricts the contact between the two ends of the rolling element 32 and the obstacle along the first direction ZZ. This reduces the friction between the rolling element 32 and the obstacle by decreasing the contact area, allowing the rolling element 32 to roll more smoothly along the surface of the obstacle. This further reduces the risk of jamming in the side brush mechanism 100, enabling the cleaning device 1000 to get rid of obstacles more quickly.
[0054] In some embodiments, the maximum radial dimension of the rolling element 32 is 2mm-12mm; the dimension of the rolling element 32 along the first direction ZZ is 2mm-12mm.
[0055] The maximum radial dimension of the rolling element 32 is located in the middle region along the first direction ZZ of the rolling element 32. The maximum radial dimension of the rolling element 32 can be 2mm, 2.5mm, 2.8mm, 3.2mm, 3.5mm, 3.88mm, 4mm, 4.25mm, 4.55mm, 4.8mm, 5.5mm, 6mm, 6.5mm, 6.8mm, 7mm, 7.5mm, 8mm, 8.2mm, 8.5mm, 9mm, 10.5mm, 11mm, 12mm, etc., but is not limited to these. The dimension of the rolling element 32 along the first direction ZZ is also the height dimension of the rolling element 32. The dimensions of the rolling element 32 along the first direction ZZ can be 2mm, 2.25mm, 2.8mm, 3mm, 3.5mm, 4mm, 4.2mm, 4.6mm, 4.9mm, 5mm, 5.5mm, 5.8mm, 6mm, 6.5mm, 6.8mm, 7mm, 7.5mm, 7.78mm, 8mm, 8.2mm, 8.5mm, 9mm, 9.5mm, 10mm, 10.5mm, 11mm, 11.6mm, 12mm, etc., but are not limited to these. The specific values of the maximum radial dimension of the rolling element 32 and the dimension of the rolling element 32 along the first direction ZZ can be selected according to the size of the swing arm 10, etc.
[0056] In some embodiments, one end of the swing arm 10 is provided with a corner region 12, which is located on the front side of the swing arm 10 along the rotation direction, and the anti-collision component 30 is provided in the corner region 12; wherein, the rotation direction is the rotation direction of the swing arm 10 when it switches from the first state to the second state.
[0057] The corner region 12 can be located at the connection area between the end 13 of the swing arm 10 away from the other end of the swing arm 10 and the side portion 14 extending from one end of the swing arm 10 to the other end of the swing arm 10; or, the corner region 12 can also be located on the side of the end 13 near the side portion 14. The side portion 14 is located on the front side of the swing arm 10 along the rotation direction when it switches from the first state to the second state. By placing the anti-collision component 30 in the corner region 12, the probability of the anti-collision component 30 contacting the obstacle first relative to the swing arm 10 can be increased, thereby reducing the risk of the swing arm 10 directly rubbing or colliding with the obstacle. This not only protects the swing arm 10 but also reduces the impact force between the side brush mechanism 100 and the obstacle, reducing the risk of wear or cracking of the side brush mechanism 100.
[0058] In some embodiments, the side brush mechanism 100 includes a plurality of anti-collision components 30, which are disposed in the corner area 12 and the side portion 14. The plurality of anti-collision components 30 disposed in the side portion 14 can be sequentially spaced along the direction from one end of the swing arm 10 to the other end of the swing arm 10. By providing a plurality of anti-collision components 30, the risk of the swing arm 10 directly rubbing or colliding with obstacles can be further reduced.
[0059] In some embodiments, the side brush mechanism 100 further includes a drive assembly 40 connected to the swing arm 10 for driving the swing arm 10 to switch between a first state and a second state; and / or, the side brush mechanism 100 further includes an elastic element 50 connected to at least the swing arm 10 and / or the drive assembly 40, the elastic element 50 being configured to deform when the swing arm 10 is in the second state and interferes with an obstacle, so that one end of the swing arm 10 moves toward the body 200; the elastic element 50 is also configured to restore its deformation when the swing arm 10 is no longer interfering with the obstacle, so as to drive one end of the swing arm 10 to move away from the body 200.
[0060] The side brush mechanism 100 has two driving modes: an active driving mode and a passive driving mode. If the side brush mechanism 100 only has a driving component 40 and no elastic element 50, then the side brush mechanism 100 only has an active driving mode. If the side brush mechanism 100 only has an elastic element 50 and no driving component 40, then the side brush mechanism 100 only has a passive driving mode. If the side brush mechanism 100 has both an elastic element 50 and a driving component 40, then the side brush mechanism 100 has both an active driving mode and a passive driving mode.
[0061] The drive assembly 40 includes a drive motor 41 and a drive shaft 42 connected to the drive motor 41. The other end of the swing arm 10 is connected to the drive shaft 42. The drive motor 41 drives the swing arm 10 to switch between a first state and a second state via the drive shaft 42. When the side brush mechanism 100 does not need to work, the swing arm 10 is in the first state. When the cleaning device 1000 detects that the side brush mechanism 100 needs to be activated for cleaning, it controls the drive motor 41 to start, so that the drive motor 41 drives the swing arm 10 to switch from the first state to the second state via the drive shaft 42.
[0062] If the side brush mechanism 100 has only a passive drive mode, the other end of the swing arm 10 rotates relative to the main body 200 via another rotating shaft (not shown), and the elastic element 50 connects the rotating shaft and / or the swing arm 10. If the side brush mechanism 100 has both an active drive mode and a passive drive mode, the other end of the swing arm 10 is connected to the drive shaft 42 of the drive assembly 40, and the elastic element 50 connects the drive shaft 42 and / or the swing arm 10. The elastic element 50 is used to deform when the swing arm 10 is in the second state and the anti-collision component 30 interferes with the obstacle, so as to drive one end of the swing arm 10 to move towards the main body 200 in a direction away from the anti-collision component 30. This allows the swing arm 10 to flexibly adjust its angle according to the obstacle situation under the action of the elastic element 50, increasing the angle between the swing arm 10 and the obstacle. This allows the swing arm 10 to face the obstacle in an inclined or horizontal posture, which helps the anti-collision component 30 to roll smoothly along the surface of the obstacle to avoid it. This not only improves the obstacle avoidance capability of the side brush mechanism 100, but also reduces the impact force between the side brush mechanism 100 and the obstacle, reducing the risk of damage to the side brush mechanism 100. The elastic element 50 can also restore its deformation when the swing arm 10 is no longer interfering with the obstacle, so as to drive one end of the swing arm 10 to move away from the main body 200, so that the side brush mechanism 100 can continue to expand the cleaning range of the area to be cleaned.
[0063] In some embodiments, the elastic element 50 may be a spring or a torsion spring, but is not limited thereto.
[0064] Please refer to the above as well. Figure 9 , Figure 9This is an exploded structural diagram of another embodiment of the side brush mechanism provided in this application. In some embodiments, the side brush mechanism 100 further includes a positioning detection component 70, which is disposed on the swing arm 10 and is used to detect the rotation angle of the swing arm 10 and determine whether the swing arm 10 is obstructed by the rotation angle of the swing arm 10. For example, when the anti-collision component 30 collides with an obstacle, the swing arm 10 will vibrate, or one end of the swing arm 10 will move towards the main body 200 under the action of the elastic element 50. The vibration of the swing arm 10 and the movement of one end of the swing arm 10 towards the main body 200 under the action of the elastic element 50 will both cause a change in the rotation angle of the swing arm 10. Moreover, the magnitude of the angle change of the swing arm 10 caused by the two is different from the magnitude of the angle change of the swing arm 10 caused by the active driving of the swing arm 10 by the drive component 40. The position detection component 70 can at least determine whether the swing arm 10 is obstructed by detecting the magnitude of the angle change of the swing arm 10, thereby realizing the detection of the obstruction of the swing arm 10. This allows the cleaning equipment 1000 to take timely measures, such as changing the movement posture of the swing arm 10 by the drive component 40, changing the movement posture of the cleaning equipment 1000, or prompting the user to remove the obstruction. This enables the cleaning equipment 1000 to get rid of the obstruction more quickly and continue the cleaning operation, thereby further improving the obstacle avoidance ability of the cleaning equipment 1000 and further improving the cleaning effect of the cleaning equipment 1000.
[0065] In some embodiments, the side brush mechanism 100 further includes a housing 60 for fixing to the main body 200, and the housing 60 has a first receiving groove 60a, and the other end of the swing arm 10 opposite to one end is rotatably disposed in the first receiving groove 60a.
[0066] If the side brush mechanism 100 only has a passive drive mode, the rotating shaft is located in the first receiving groove 60a. The rotating shaft can be rotatably connected to the housing 60, and the other end of the swing arm 10 is fixedly connected to the rotating shaft. When the anti-collision component 30 interferes with the obstacle, the elastic element 50 can drive the rotating shaft to rotate, so that the rotating shaft drives the rotating shaft to rotate. Alternatively, the rotating shaft can also be fixedly connected to the housing 60, and the other end of the swing arm 10 can be rotatably connected to the rotating shaft. When the anti-collision component 30 interferes with the obstacle, the elastic element 50 can drive the swing arm 10 to rotate. If the side brush mechanism 100 has an active drive mode and a passive drive mode, or only an active drive mode, then the drive motor 41 and drive shaft 42 of the drive component 40 are both located in the first receiving groove 60a, and the drive shaft 42 is connected to the other end of the swing arm 10.
[0067] The housing 60 serves as the basic carrier of the side brush mechanism 100. During assembly, the swing arm 10, housing 60, side brush body 20, anti-collision component 30, and drive component 40 can be assembled into a whole to form the side brush mechanism 100, and then the housing 60 is used to fix it to the main body 200. The housing 60 and the main body 200 can be fixed together by means of bolt connection, riveting connection, snap connection, or adhesive bonding.
[0068] In some embodiments, a second receiving groove 200b is formed at the bottom of the main body 200, and the housing 60 is at least partially disposed within the second receiving groove 200b, so that the side brush mechanism 100 does not protrude from the bottom of the main body 200.
[0069] Please continue to refer to Figures 1 to 4 This application also provides a cleaning device 1000. The cleaning device 1000 includes a main body 200 and a side brush mechanism 100 as described in any of the above embodiments.
[0070] In this embodiment, the specific structure of the side brush mechanism 100 is as described in the above embodiments. Since the cleaning device 1000 adopts all the technical solutions of all the embodiments of the side brush mechanism 100, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
[0071] This application provides a side brush mechanism 100 and a cleaning device 1000. The side brush mechanism 100 is used in the cleaning device 1000. The side brush mechanism 100 includes a swing arm 10, a side brush body 20 and an anti-collision component 30. The swing arm 10 is disposed on the main body 200 and can rotate relative to the main body 200. The side brush body 20 is disposed at one end of the swing arm 10. The anti-collision component 30 is roll-connected to one end of the swing arm 10 and at least protrudes beyond the front contour of the swing arm 10. By rollingly connecting the anti-collision component 30 to one end of the swing arm 10, and ensuring that the anti-collision component 30 protrudes at least beyond the front contour of the swing arm 10, the anti-collision component 30 contacts the obstacle first relative to the swing arm 10 during the operation of the side brush mechanism 100. Furthermore, the anti-collision component 30 can roll into contact with the obstacle. On one hand, this allows the cleaning equipment 1000 to navigate around the obstacle's contour via the anti-collision component 30, helping it to turn or adjust its position. This reduces the risk of the side brush mechanism 100 getting stuck, allowing it to quickly overcome the obstacle and continue cleaning operations, effectively improving its cleaning efficiency and effectiveness. On the other hand, it reduces the risk of the swing arm 10 directly rubbing or colliding with the obstacle, thus reducing the impact force between the side brush mechanism 100 and the obstacle. This further reduces the risk of wear or cracking of the side brush mechanism 100, extending its service life.

Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
