[0033] To help those skilled in the art understand this application more clearly, the following will provide a clear and complete description of the technical solutions in the embodiments of this application, in conjunction with the accompanying drawings. Obviously, the described embodiments are only a portion of the embodiments of this application, not all of them. All other embodiments derived by those skilled in the art based on the embodiments of this application without creative effort are also within the scope of protection of this application.

[0034] In related technologies, the side brushes of cleaning devices such as robot vacuums rotate continuously during operation. When the cleaning device is climbing over obstacles or carpets, these side brushes can hinder the machine's climbing or cause the carpet to roll up, causing malfunctions and impacting the user experience. Furthermore, when cleaning corners and other areas, the side brushes cannot be adjusted, resulting in limited cleaning effectiveness and room for improvement.

[0035] Based on the above technical problems, the present application provides a side brush element suitable for various cleaning conditions.

[0036] The side brush element provided herein includes a base, a side brush body, and a drive member. The side brush body rests against the side of the base, is provided with a first guide portion, and the drive member is provided with a second guide portion. The second guide portion cooperates with the first guide portion to drive the side brush body to rise, fall, and / or swing.

[0037] Specifically, when the cleaning device is climbing over obstacles or carpets, the second guide portion and the first guide portion cooperate to keep the side brush body in a raised position to avoid obstacles or carpets, allowing the device to operate normally and improving the user experience. When the cleaning device is cleaning corners or other cleaning conditions, the second guide portion and the first guide portion cooperate to cause the side brush body to swing, improving the cleaning effect, which is very practical.

[0038] Based on the above design ideas, this application further describes the side brush assembly.

[0039] FIG1 is a schematic diagram showing the side brush element in a first cleaning position in one or more embodiments of the present application. FIG2 is a schematic diagram showing the side brush element in FIG1 from another perspective. FIG3 is a schematic diagram showing the side brush element in FIG1 in an obstacle avoidance position. FIG4 is a schematic diagram showing the side brush element in FIG3 from another perspective.

[0040] With reference to Figures 1 to 4 , the present application provides a side brush element comprising a base 1, a side brush body 2, and a drive member 3. The side brush body 2 rests against the side of the base 1, and a first guide portion 21 is provided at the bottom of the side brush body 2. The drive member 3 is rotatably connected to the side brush body 2. A second guide portion 31 is provided at the top of the drive member 3, which is matingly mounted at the bottom of the first guide portion 21. At least a portion of the second guide portion 31 and / or the first guide portion 21 is a helical surface a1.

[0041] The side brush element provided herein has a driver 3 rotatably connected to the guide shaft 22, allowing it to rotate relative to the side brush body 2. Because at least a portion of the second guide portion 31 and / or the first guide portion 21 comprises a helical surface a1, controlling the driver 3 to rotate causes the second guide portion 31 to rotate along the mating surface with the first guide portion 21, thereby lifting the side brush body 2 along the side of the base 1 and placing it in a raised position (as shown in Figures 3 and 4). This allows the side brush body 2 to avoid obstacles or carpets, ensuring normal operation of the device.

[0042] In conjunction with Figures 1 and 2, when the side brush body 2 rests against the base 1, it is in normal cleaning mode, and this position can be defined as the first cleaning position. In conjunction with Figures 3 and 4, when the side brush body 2 is raised along the side of the base 1 and in the raised position, it can be defined as the obstacle avoidance position. By controlling the side brush body 2 to switch between the first cleaning position and the obstacle avoidance position, it can adapt to different usage conditions, providing excellent practicality.

[0043] 1 to 4 , in some embodiments, the side brush element may further include a first motor 4 , and the first motor 4 is used to drive the side brush 26 on the side brush body 2 to rotate.

[0044] Figure 5 shows a schematic diagram of the side brush body, and Figure 6 shows a schematic diagram of the internal structure of the side brush body. In some embodiments, two or more transmission gears 23 are installed within the side brush body 2. One transmission gear 23 is mounted on the output end of the first motor 4, and the other transmission gear 23 is mounted on the rotating shaft of the side brush 26. The first motor 4 sequentially drives each transmission gear 23 to rotate, thereby driving the side brush 26 to perform cleaning operations. The side brush 26 is driven by two or more transmission gears 23, which, while meeting the dimensional requirements of the side brush 26, provides space for the layout of other components. In other embodiments, the first motor 4 can also be directly connected to the rotating shaft of the side brush 26, which is not a limitation here.

[0045] 1 to 4 , in some embodiments, the first motor 4 is disposed on the top of the side brush body 2 , which can reduce the overall height of the side brush body 2 to better perform cleaning work.

[0046] Figure 7 shows a schematic diagram of the structure of Figure 5 from another perspective. In conjunction with Figure 7, in some embodiments, a columnar body may be provided at the bottom of the side brush body 2. This columnar body may be integrally formed with the outer shell of the side brush body 2 to serve as a guide shaft 22 for the drive body. This guide shaft 22 may be coaxial with the output end of the first motor 4, or it may be non-coaxial with the output end of the first motor 4, without limitation.

[0047] 7 , in some embodiments, a first guide protrusion 24 may be provided at the bottom of the side brush body 2. This first guide protrusion may be integrally formed with the outer shell of the side brush body 2. The first guide portion 21 is provided on the side of the first guide protrusion 24 facing away from the side brush body 2, i.e., the first guide protrusion 24 is provided at the bottom of the first guide protrusion 24.

[0048] In some embodiments, the driving member 3 is rotatably mounted on the guide shaft 22 , and the driving member 3 can be controlled to rotate around the guide shaft 22 .

[0049] Figure 8 shows a schematic diagram of the structure of the driver. In some embodiments, the top of the driver 3 can be provided with a second guide protrusion 32, which can be integrally formed with the driver 3. The second guide portion 31 is provided on the side of the second guide protrusion 32 facing away from the driver 3, that is, the second guide protrusion 32 is provided on the top of the driver 3.

[0050] Because at least a portion of the second guide portion 31 and / or the first guide portion 21 is a helical surface a1, the driving member 3 is controlled to rotate about the guide shaft 22, causing the second guide portion 31 of the driving member 3 to rotate relative to the first guide portion 21. When the side brush body 2 is in the first cleaning position, during the process of the driving member 3 rotating about the guide shaft 22, the side brush body 2 abuts against the base 1 and cannot rotate with the driving member 3. This causes the second guide portion 31 of the driving member 3 to rotate along the mating surface with the first guide portion 21, driving the first guide portion 21 to rise, thereby raising the side brush body 2 to a set height, causing the side brush body 2 to switch from the first cleaning position to the obstacle avoidance position to avoid obstacles or carpets, thereby ensuring normal operation of the device and improving the user experience.

[0051] 7 and 8 , in some embodiments, at least portions of the second guide portion 31 and the first guide portion 21 are both helical surfaces a1. In other embodiments, the second guide portion 31 may be the helical surface a1 and the first guide portion 21 may be a flat surface, or the second guide portion 31 may be a flat surface and the first guide portion 21 may be the helical surface a1, without limitation.

[0052] In conjunction with Figures 7 and 8 , in some embodiments, the second guide portion 31 and the first guide portion 21 further have a planar portion a2 that can be in contact with each other. After the second guide portion 31 drives the first guide portion 21 to rise to a set height, the second guide portion 31 continues to rotate, causing the planar portion a2 on the first guide portion 21 to rest on the planar portion a2 of the second guide portion 31, as shown in Figure 9 . This stabilizes the side brush body 2 and keeps it in a raised position, thereby maintaining it in an obstacle avoidance position. Furthermore, if the power member 8 that drives the drive member 3 to rotate stops operating, the side brush body 2 can also be kept in a raised position, thereby maintaining it in an obstacle avoidance position.

[0053] In conjunction with Figures 7 and 8 , in some embodiments, the projection of the first guide protrusion 24 on the side brush body 2 and the projection of the second guide protrusion 32 on the driver 3 can both be arc-shaped, meaning that both the first guide protrusion 24 and the second guide protrusion 32 are non-enclosed structures. When the driver 3 rotates about the guide shaft 22 and the second guide protrusion 32 on the driver 3 rotates below the first guide protrusion 24, the second guide portion 31 and the first guide portion 21 cooperate to drive the first guide portion 21 upward, thereby raising the side brush body 2 to a set height. This allows the side brush body 2 to avoid obstacles or carpets, ensuring normal operation of the device and improving user experience.

[0054] 7 , in some embodiments, the first guide protrusion 24 may be spaced apart from the guide shaft 22 so that a guide space is formed between the first guide protrusion 24 and the guide shaft 22 .

[0055] Figure 10 shows a schematic diagram of the base structure. Referring to Figures 1 to 4 and 10 , the base 1 can be provided with a guide bushing 5. The drive member 3 is rotatably mounted on the guide bushing 5. The guide shaft 22 is liftably inserted into the guide bushing 5. The first guide protrusion 24 is rotated onto the outer circumference of the guide bushing 5. Specifically, when the side brush body 2 is in the first cleaning position, the guide bushing 5 is positioned within the first guide protrusion 24 (i.e., within the guide space), filling the guide space. This not only stably supports the side brush body 2 and prevents it from shaking, but also prevents impurities, particularly lint on the surface being cleaned, from entering the guide space and potentially affecting the operation of the device. When the side brush body 2 switches from the first cleaning position to the obstacle avoidance position, the first guide portion 21 rotates relative to the guide bushing 5, and the guide shaft 22 is relatively lifted within the guide bushing 5, causing the guide bushing 5 to rotate out of the first guide protrusion 24 (i.e., the guide space).

[0056] In some embodiments, the guide bushing 5 can be integrally formed on the base 1, the guide shaft 22 can be inserted into the guide bushing 5 with a clearance fit, and the driving member 3 can also be assembled on the guide bushing 5 with a clearance fit, so that the guide shaft 22 and the driving member 3 can both rotate relative to the guide bushing 5, which will not be elaborated here.

[0057] It should be noted that a guide groove may also be provided at the bottom of the side brush body 2, and the first guide portion 21 is provided at the bottom of the guide groove. The specific implementation scheme is similar to the above and will not be described here.

[0058] In conjunction with Figures 1 and 10 , in some embodiments, the side brush element may further include a stopper 6. This stopper 6 is disposed along the rotational path of the driver 3 to limit the rotational angle of the driver 3. Specifically, when the driver 3 rotates and the flat surface a2 of the first guide portion 21 of the side brush body 2 rests on the flat surface a2 of the second guide portion 31, the driver 3 is blocked by the stopper 6 and stops rotating, placing the side brush body 2 in an obstacle avoidance position and maintaining a raised position, thereby enabling the side brush body 2 to avoid obstacles or carpets.

[0059] In conjunction with Figures 1 to 4 and 8 , in some embodiments, a notch 33 may be provided on the circumference of the driver 3, with the stopper 6 positioned within the notch 33. A distance exists between the stopper 6 and the notch 33, allowing the driver 3 to rotate a set angle to elevate the side brush body 2. When the side brush body 2 is raised to its proper position, the driver 3 is blocked by the stopper 6, stopping rotation and maintaining the side brush body 2 in its raised position.

[0060] In other embodiments, the notch 33 may not be provided on the circumference of the driving member 3. For example, the driving member 3 may be annular, the limiting member 6 may be provided on the outer side of the circumference of the driving member 3, and a stopper may be provided on the circumference of the driving member 3. The stopper may be blocked by the limiting member to prevent the rotation of the driving member 3. This method will occupy a large space.

[0061] In conjunction with Figures 1 to 4 , in some embodiments, the side brush element may further include a position sensor 7 . Position sensor 7 is used to determine the height of the side brush body 2 . Specifically, when the side brush body 2 rises to the obstacle avoidance position, position sensor 7 confirms that the side brush body 2 has reached its position and sends a signal indicating that the side brush body 2 has reached its position to the controller. In response to this signal, the controller issues a command to stop the driving member 3 , controlling the driving member 3 to stop rotating and maintaining the side brush body 2 in its raised position.

[0062] In some embodiments, the rotation of the driver 3 can be controlled by providing a limiter 6 or by using a position sensor 7. In some embodiments, both the limiter 6 and the position sensor 7 can be included to achieve simultaneous hardware and software control, or only one of the above implementation methods can be included, without limitation.

[0063] Figure 11 shows a schematic diagram of the assembly of the driver and power member. In conjunction with Figures 1 to 4, 8, and 11, in some embodiments, at least a portion of the circumference of the driver 3 may be provided with transmission teeth 34. The side brush element may also include a power member 8, the output end of which may be provided with a gear 81, which is in transmission connection with the meshing teeth on the driver 3. In specific implementation, when the power member 8 is activated, the gear 81 on the power member 8 drives the driver 3 to rotate about the guide shaft 22, causing the second guide portion 31 of the driver 3 to rotate along the mating surface with the first guide portion 21, thereby driving the first guide portion 21 to lift, thereby lifting the side brush body 2. When the driver 3 is blocked by the limit member 6, the power member 8 stops outputting, the driver 3 stops rotating, and the side brush body 2 remains lifted.

[0064] 1 to 4 , in some embodiments, the power member 8 may be a second motor, which may be arranged in parallel with the first motor 4 , and the second motor may be arranged above the driving member 3 , thereby reducing the space occupied by the motor.

[0065] In other embodiments, the output end of the power member 8 may also be directly coaxially connected to the driving member 3. For example, the power member 8 is disposed below the driving member 3.

[0066] Referring to Figure 10 , in some embodiments, a through-hole 11 may be provided on the circumferential surface of the base 1. One end of the side brush body 2 is connected to the base 1, and the other end of the side brush body 2 passes through the through-hole 11. The side brush body 2 can be raised and lowered within the through-hole 11 along the sidewalls of the through-hole 11. A accommodating chamber 12 is provided within the base 1, and the aforementioned drive member 3, power member 8, stopper 6, and first motor 4 can all be disposed within the base 1. The guide bushing 5 can be fixed to the bottom of the base 1 through an integral molding process, with the guide shaft 22 loosely inserted into the guide bushing 5. The bottom of the drive member 3 can be snugly mounted on the bottom of the base 1 and loosely fitted onto the guide bushing 5. The stopper 6 can also be integrally molded and fixed to the bottom of the base 1. The position sensor 7 can be disposed within or outside the base 1, without limitation.

[0067] In conjunction with Figures 1 to 4, 10, and 14, in some embodiments, the passage 11 may include a connected swinging opening 111 and a stop opening 112. The stop opening 112 is located above the swinging opening 111, allowing the side brush body 2 to swing within the swinging opening 111 and rotate into the stop opening 112. When the side brush body 2 rests against one side of the swinging opening 111, it is in a first cleaning position and in normal cleaning mode. If an obstacle or carpet is encountered, the driving member 3 can be controlled to rotate, causing the side brush body 2 to rise along one side of the swinging opening 111, placing the side brush body 2 in a raised position and switching to an obstacle avoidance position to avoid the obstacle or carpet. Alternatively, the side brush body 2 can be controlled to swing from one side of the swinging opening 111 to the other side to adjust its angle on the base 1, allowing it to clean corners and other special conditions (as shown in Figure 12). During the process of the side brush body 2 swinging to the other side of the swing opening 111, the guide shaft 22 on the side brush body 2 rotates in the guide bushing 5. Under the condition that the side brush body 2 swings to the other side of the swing opening 111, the position of the side brush body 2 can be defined as the second cleaning position.

[0068] In conjunction with Figures 1 to 4, 10, 12, and 14, in some embodiments, the swing opening 111 has a first side wall b1 and a second side wall b2 that are opposed to each other. The stop opening 112 has a third side wall b3 and a fourth side wall b4 that are opposed to each other. The third side wall b3 and the first side wall b1 are located on the same straight line. The side brush body 2 can be raised or lowered along the straight line between the first side wall b1 and the third side wall b3. The fourth side wall b4 is disposed between the first side wall b1 and the second side wall b2, i.e., the top projection of the fourth side wall b4 falls within the swing opening 111. In a specific implementation, the central angle formed by the swing opening 111 relative to the guide shaft 22 is greater than the central angle formed by the stop opening 112 relative to the guide shaft 22. The size of the swing opening 111 is greater than the size of the outer shell of the side brush body 2, and the size of the stop opening 112 is substantially the same as the size of the outer shell of the side brush body 2. When the side brush body 2 is in the first cleaning position, the power member 8 is deactivated, and the first motor 4 drives the side brush on the side brush body 2 to rotate. The second guide portion 31 on the drive member 3 and the first guide portion 21 on the side brush body 2 are in contact with each other, the side brush body 2 rests against the first side wall of the swing opening 111, and the drive member 3 and the limit member 6 are separated. When encountering an obstacle or passing through a carpet, the power member 8 is activated to rotate. Because the side brush body 2 rests against the first side wall of the swing opening 111, the side brush body 2 cannot rotate. The second guide portion 31 of the drive member 3 drives the first guide portion 21 to lift, causing the side brush body 2 to rise along the line between the first and third side walls and into the limit opening 112. This allows the side brush body 2 to remain in the raised position, allowing it to avoid obstacles or pass through carpet, ensuring normal operation of the device and improving the user experience. When the device avoids an obstacle or passes through a carpet, the power member 8 can be controlled to rotate in the opposite direction, so that the second guide portion 31 of the driving member 3 rotates in a direction away from the first guide portion 21 on the side brush body 2, so that the side brush body 2 drops from the limiting opening 112 into the swing opening 111 and abuts against the first side wall of the swing opening 111, and continues to maintain the first cleaning position.

[0069] In conjunction with Figures 1 to 4 , in some embodiments, the side brush element may further include a reset member 9. This reset member 9 is disposed between the side brush body 2 and the base 1. When the side brush body 2 is in the first cleaning position, the reset member 9 is deformed, and the side brush body 2 is lifted, forcing the reset member 9 to continue deforming, thereby switching the side brush body 2 from the first cleaning position to the obstacle avoidance position. When the side brush body 2 switches from the obstacle avoidance position to the first cleaning position, the reset member 9 resumes its deformation, applying a force to the side brush body 2 to maintain contact between the first guide portion 21 of the side brush body 2 and the second guide portion 31 of the drive member 3, allowing the side brush body 2 to smoothly return to the first cleaning position.

[0070] Under the condition that the reset member 9 is provided, when the device avoids an obstacle or passes through a carpet, there is no need to control the power member 8 to rotate in the opposite direction. The side brush body 2 can be moved downward by relying on the reset member 9 to restore its deformation and apply a force to the side brush body 2, thereby driving the driving member 3 to rotate in the opposite direction until the side brush body 2 falls from the limiting opening 112 into the passing opening 11 and abuts against the first side wall of the swing opening 111, and continues to maintain the first cleaning position.

[0071] 1 to 4 , in some embodiments, the reset member 9 may be disposed between the top of the side brush body 2 and the base 1. When the side brush element is in a cleaning mode or in a raised position, the reset member 9 is in a compressed state.

[0072] Figure 13 shows a schematic diagram of the reset member. In conjunction with Figures 1 to 4 and 13, in some embodiments, the reset member 9 can be mounted on the first motor 4. The reset member 9 has two connecting ends, a first connecting end 91 and a second connecting end 91, which are connected to the base 1 and the side brush body 2, respectively.

[0073] In conjunction with Figures 1 to 4 and Figure 13, during specific implementation, a first limiting groove 13 can be provided on the circumferential surface of the base 1. The first limiting groove 13 is connected to the through-hole, that is, the opening of the first limiting groove 13 faces downward, and the first connecting end 91 of the reset member 9 is disposed in the first limiting groove 13. A connecting block 25 is provided on the side brush body 2. A second limiting groove 27 with an opening facing the circumference is formed between the connecting block 25 and the side brush body 2. The other connecting end of the reset member 9 is disposed in the second limiting groove 27 to facilitate assembly of the reset member 9 on the side brush assembly. In other embodiments, the two connecting ends of the reset member 9 can be welded to the side wall of the base 1 and the top of the side brush body 2, respectively, without limitation herein.

[0074] As can be seen from the above, the above-mentioned reset member 9 is a composite structure composed of a compression spring and a torsion spring, which can provide axial thrust and circumferential tension at the same time, so that the side brush body 2 is subjected to axial thrust and axial tension at the same time, so that in the absence of the action of the power member 8, the first guide portion 21 of the side brush body 2 and the second guide portion 31 of the driving member 3 are always in a fitted state (as shown in Figure 14).

[0075] It should be noted that the reset member 9 can also be arranged between the bottom of the side brush body 2 and the base 1. When the side brush element is in the first cleaning position or switched to the obstacle avoidance position, the reset member 9 is in a stretched deformation state.

[0076] Because the size of the limiting opening 112 is smaller than that of the swinging opening 111, the side brush body 2 can swing within the swinging opening 111, allowing the angle of the side brush body 2 on the device to be adjusted. In specific implementation, the power member 8 can be controlled to rotate in the reverse direction. Because the reset member 9 applies a force to the side brush body 2, the first guide portion 21 of the side brush body 2 and the second guide portion 31 of the driving member 3 are always in contact, causing the side brush body 2 and the driving member 3 to rotate synchronously until the side brush body 2 abuts the second side wall of the swinging opening 111. At this point, the side brush body 2 is in the second cleaning position, and the angle of the side brush body 2 on the device can be adjusted to achieve cleaning in special working conditions such as corners. After cleaning special working conditions such as corners, the power member 8 can be controlled to rotate in the forward direction. Since the reset member 9 applies a force to the side brush body 2, the first guide portion 21 of the side brush body 2 and the guide portion of the second body are always in a fit state, so that the side brush body 2 and the driving member 3 rotate synchronously under the drive of the power member 8 until the side brush body 2 abuts against the first side wall of the swing opening 111, so that the side brush body 2 is in the first cleaning position and continues to maintain the normal cleaning mode.

[0077] It should be noted that when the first guide portion 21 of the side brush body 2 and the second guide portion 31 of the driver 3 are in contact, if the side brush 26 encounters an obstacle or the force applied by the user to the side brush 26 is greater than the force applied by the reset member 9, the first guide portion 21 of the side brush body 2 can separate from the second guide portion 31 of the driver 3. In this case, the driver 3 is not driven to rotate by the guide portion, thus protecting the power member 8 and the transmission between the power member 8 and the driver 3 from damage.

[0078] In addition, in some embodiments, at least a portion of the first guide portion 21 of the side brush body 2 and the second guide portion 31 of the driver 3 are inclined surfaces, allowing the driver 3 to reciprocate in a straight line. When the side brush body 2 is in the first cleaning position, the driver 3 moves toward the side brush body. Because the side brush body 2 rests against the base 1, the driver 3 cannot push the side brush body 2. This causes the second guide portion 31 of the driver 3 to move along the mating surface with the first guide portion 21, driving the first guide portion 21 to rise, thereby raising the side brush body 2 to a set height. This allows the side brush body 2 to switch from the first cleaning position to the obstacle avoidance position, avoiding obstacles or carpets, thereby ensuring normal operation of the device and improving the user experience. Simultaneously, the driver 3 can be controlled to move in the opposite direction. Under the pressure of the reset member 9, the side brush body 2 can be driven to the second cleaning position to accommodate special cleaning conditions such as corners, thereby improving cleaning efficiency and providing excellent practicality.

[0079] In summary, the side brush element provided in the present application can be switched between the first cleaning position, the second cleaning position and the obstacle avoidance position to adapt to different cleaning conditions, and has good practicality.

[0080] Based on the above-mentioned side brush element, the present application also provides a cleaning device, which includes a main body and the above-mentioned side brush element, and the above-mentioned side brush element is assembled on the main body.

[0081] The cleaning device having the above-mentioned side brush element has a side brush body 2 that can switch between a first cleaning position, a second cleaning position, and an obstacle avoidance position to adapt to different cleaning conditions, and has good practicality.

[0082] In some embodiments, a controller and various sensors may be installed on the main unit. The sensors monitor the surrounding environment and transmit corresponding monitoring parameters to the controller, which then controls the movement of the side brush element based on the monitoring parameters.
