[0031] On a robot vacuum cleaner, the side brush 2 on the chassis 1 extends outward from the periphery of the chassis 1, allowing it to clean corners in the room that are beyond the reach of the chassis 1. However, when the side brush 2 is stored inward after shutdown, it remains in contact with the ground, easily knocking away debris collected under the chassis 1 and becoming entangled with hair and other debris.
[0032] like Figure 1-Figure 2 As shown, this embodiment provides a sweeping robot for cleaning a surface. The sweeping robot comprises a chassis 1 , a side brush 2 and a rotating drive member 3 .
[0033] The body chassis 1 is used to move on the surface to be cleaned. The side brush 2 includes a rotating base 21 and a cleaning brush 22. The mounting end of the cleaning brush 22 is set on the rotating base 21. The rotating base 21 is rotatably set on the body chassis 1. The rotation axis of the rotating base 21 is not perpendicular to the surface to be cleaned. The rotating drive member 3 is used to drive the rotating base 21 to rotate forward or reverse. When the rotating base 21 rotates forward, the brushing end of the cleaning brush 22 moves away from the body chassis 1 toward the outer periphery of the body chassis 1 and gradually approaches the surface to be cleaned. When the rotating base 21 reverses, the brushing end of the cleaning brush 22 moves closer to the body chassis 1 and gradually moves away from the surface to be cleaned. In this embodiment, the rotating drive member 3 can be a motor.
[0034] In the sweeping robot provided by this embodiment, since the rotation axis of the rotating seat 21 is not perpendicular to the surface to be cleaned, the cleaning surface formed by the rotation of the cleaning brush 22 around the rotation axis intersects with the surface to be cleaned at an angle. Therefore, when the cleaning brush 22 rotates to the outside of the body chassis 1, the cleaning brush 22 contacts the surface to be cleaned to clean the surface. When the cleaning brush 22 rotates to the inside of the body chassis 1, the cleaning brush 22 is separated from the surface to be cleaned, thereby preventing the hair of the cleaning brush 22 from being entangled on the side brush 2 or the dust on the body chassis 1 from being swept out from the bottom of the body chassis 1 by the side brush 2 during the process of stopping and retracting the cleaning brush 22, thereby avoiding affecting the roller brush on the sweeping robot from sweeping the hair, dust, etc. under the body chassis 1 into the dust box.
[0035] Optionally, a rotatable shaft 4 is provided on the chassis 1. The shaft 4 is not perpendicular to the surface being cleaned. The rotating seat 21 is provided on the shaft 4, and the shaft 4 is in transmission connection with the rotary drive member 3. The chassis 1 is generally parallel to the surface being cleaned so as to be stably positioned on the surface being cleaned. Therefore, the shaft 4 has a certain inclination angle relative to the chassis 1, rather than being perpendicular to the chassis 1, so that the height of the cleaning brush 22 changes during rotation.
[0036] like Figure 2 and Figure 3As shown, optionally, the sweeping robot further includes an outward swing assembly 7, one end of which is rotatably mounted on the chassis 1, and a rotating shaft 4 is rotatably mounted on the other end of the outward swing assembly 7. The side brush 2 is further extended by the outward swing assembly 7, so that the side brush 2 extends outward to a greater extent, thereby improving the cleaning coverage of corners by the sweeping robot. The outward swing assembly 7 and the side brush 2 can each be swung outward and retracted, making the sweeping robot compact. In this embodiment, the outward swing assembly 7 is arranged on the lower side of the chassis 1, and the side brush 2 is arranged on the lower side of the outward swing assembly 7, which helps to reduce the overall height of the sweeping robot.
[0037] like Figure 3 and Figure 4 As shown, the sweeping robot optionally further includes a first rotating shaft 8 and a first transmission gear set 9. The outer swing assembly 7 is rotatably mounted on the chassis 1 via the first rotating shaft 8. The rotary drive member 3 is in transmission connection with the first rotating shaft 8, and the rotary shaft 4 is in transmission connection with the first rotating shaft 8 via the first transmission gear set 9. The interconnected transmission connection between the first rotating shaft 8, the first transmission gear set 9, and the rotary shaft 4 enables the rotary drive member 3 to synchronously drive the outer swing assembly 7 and the side brush 2. This allows for coordinated operation of the side brush 2 and the outer swing assembly 7, resulting in a compact structure. In this embodiment, the outer swing assembly 7 is a hollow shell with a receiving cavity within it. The first transmission gear set 9 is disposed within the cavity, resulting in a compact and highly damage-resistant structure. The sweeping robot further includes a second transmission gear set 10, which is transmission-connected between the output shaft of the rotary drive member 3 and the first rotating shaft 8 to regulate the output torque and output speed of the rotary drive member 3.
[0038] like Figure 4 As shown, optionally, the output shaft of the rotary drive member 3 is perpendicular to the surface being cleaned, and a helical gear 5 is provided on the rotating shaft 4, which is drivingly connected to the output shaft of the rotary drive member 3. In other words, the helical teeth of the helical gear 5 drivingly connect the output shaft and the rotating shaft 4, which are inclined relative to each other. In this embodiment, the output shaft of the rotary drive member 3 is perpendicular to the base surface of the machine chassis 1.
[0039] like Figure 4 As shown, the sweeping robot optionally further includes a damping gear 6, which is in transmission connection with the helical gear 5. The damping gear 6 can effectively reduce mechanical vibration and noise, and improve the swinging stability of the side brush 2. In this embodiment, the damping gear 6 is connected to the first rotating shaft 8 through gear meshing.
[0040] like Figure 5 As shown, optionally, a recessed portion 211 is provided on the rotating base 21, and the rotating shaft 4 is inserted into the recessed portion 211 and connected to the rotating base 21. In other words, the side brush 2 is connected to the rotating shaft 4 through the recessed portion 211, and the connection is compact and reliable.
[0041] like Figure 5As shown, the side brush 2 optionally includes an extension rod 23, which is inclined relative to the surface being cleaned. One end of the extension rod 23 is disposed on the rotating base 21, and the other end is provided with a cleaning brush 22. The extension rod 23 is inclined relative to the surface being cleaned, so that the cleaning brush 22 has a larger swing range in height, which facilitates separation from or contact with the surface being cleaned.
[0042] like Figure 5 As shown, the cleaning brush 22 optionally comprises a strip brush that is tilted toward the surface being cleaned, with one end of the strip brush positioned on the rotating base 21. Similar to the extension rod 23, the strip brush also increases the height swing range of the sweeping end of the cleaning brush 22, thereby facilitating separation from or contact with the surface being cleaned. In this embodiment, the extension rod 23 and the cleaning brush 22 extend in the same direction.
[0043] like Figure 5 As shown, optionally, the cleaning brush 22 includes only one strip brush. Compared with the prior art using three side brushes 2, the present application uses one strip brush as the cleaning brush 22, which can significantly reduce entanglement with hair and other garbage, making it easier for the sweeping robot to clean itself.
[0044] like Figure 5 As shown, a magnet 11 is further provided on the rotating seat 21. In this embodiment, a Hall effect detector is provided on the chassis 1, which detects the change in the magnetic field generated by the magnet 11 and the position of the rotating seat 21, thereby determining the rotation angle of the side brush 2 and the swing angle of the outer swing assembly 7.
[0045] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
