[0045] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0046] According to the first aspect of this application, referring to Figures 1 to 6 This application provides a side brush device. The side brush device includes a telescopic member 1 and a side brush assembly 2. The telescopic member 1 has a telescopic shaft 11. The telescopic member 1 is configured to be fixedly connected to the main body structure 3. The side brush assembly 2 is configured to be rotatably mounted on the main body structure. The telescopic shaft 11 is connected to the side brush assembly 2 and is used to drive the side brush assembly 2 to swing.

[0047] In this embodiment, the side brush assembly 2 is driven to swing by the telescopic shaft 11 of the telescopic member 1, so that the side brush assembly 2 can swing out of the space where the main body 3 is located, and the side brush assembly 2 can clean the right angle position of the wall or the edge of the wall, so as to ensure the cleaning effect.

[0048] It is understandable that the telescopic shaft 11 of the telescopic component 1 can extend and retract. This extension and retraction of the telescopic shaft 11 can drive the side brush assembly 2 to oscillate around its rotational connection point with the main body mechanism 3. For example... Figure 5 As shown, when the telescopic shaft 11 is in the retracted state, the side brush 22 of the side brush assembly 2 can be completely located below the main body mechanism 3, or most of the side brush 22 of the side brush assembly 2 can be located below the main body mechanism 3, with a small portion located outside the space where the main body mechanism 3 is located. Figure 6 As shown, when the telescopic shaft 11 is in the extended state, the side brush 22 of the side brush assembly 2 can be completely located outside the space where the main body mechanism 3 is located, or a small part of the side brush 22 of the brush assembly is located below the main body mechanism 3, and most of the part is located outside the space where the main body mechanism 3 is located.

[0049] In this embodiment of the application, the side brush 22 of the side brush assembly 2 being located outside the space where the main body mechanism 3 is located means that the projection of the side brush 22 is located outside the projection of the main body mechanism 3 along the height direction of the main body mechanism 3.

[0050] It should be noted that, to ensure that the telescopic shaft 11 can drive the side brush assembly 2 to swing on the main body 3, the connection between the telescopic shaft 11 and the side brush assembly 2 is located away from the rotational connection between the side brush assembly 2 and the main body 3, and the telescopic shaft 11 and the side brush 22 of the side brush assembly 2 are located on opposite sides of the side brush assembly 2. Specifically, the side brush assembly 2 includes a second housing 213. The middle part of the second housing 213 is rotatably connected to the main body 3. The telescopic shaft 11 is rotatably connected to the first end of the second housing 213, and the side brush 22 is rotatably disposed at the second end of the second housing 213. Thus, the telescopic shaft 11 can drive the side brush assembly 2 to swing during the extension and retraction process, and adjust the position of the side brush 22. Based on the telescopic shaft 11, the position of the side brush 22 of the side brush assembly 2 is adjusted. When the main body 3 is located away from the wall, the telescopic shaft 11 is in a retracted state; when the main body 3 is close to the wall at a right angle or at the wall edge, the telescopic shaft 11 is in an extended state.

[0051] like Figure 1 As shown, in some embodiments, the telescopic shaft 11 is angled to the drive assembly so that the telescopic shaft 11 drives the side brush assembly 2 to swing on the main body 3. For example, the side brush assembly 2 is generally a strip-shaped structure. The middle part of the side brush assembly 2 is rotatably connected to the main body 3. The telescopic shaft 11 is rotatably connected to the first end of the side brush assembly 2. The side brush 22 is rotatably disposed at the second end of the side brush assembly 2. When the telescopic shaft 11 is in the retracted state, the telescopic shaft 11 and the side brush 22 are set at a right angle; when the telescopic shaft 11 is in the extended state, the telescopic shaft 11 and the side brush 22 are set at an acute angle.

[0052] In some embodiments, the telescopic member 1 can be an electric telescopic rod, which realizes the reciprocating extension and retraction of the telescopic shaft 11 by electric means. Alternatively, the telescopic member 1 can also be a telescopic mechanism such as a cylinder or hydraulic cylinder, so that the telescopic shaft 11 of the telescopic member 1 can drive the side brush assembly 2 to swing.

[0053] In some embodiments, the main body 3 is the middle frame of the robotic vacuum cleaner. The telescopic component 1 is fixedly installed on the middle frame, and the fixing method includes, but is not limited to, fastening, welding, bonding, and heat fusion connection. The side brush assembly 2 is rotatably installed on the bottom of the middle frame.

[0054] like Figure 1 and Figure 2 As shown, in some embodiments, the telescopic member 1 includes a first drive unit 12. The telescopic shaft 11 is connected to the first drive unit 12.

[0055] It is understandable that the first drive unit 12 is the drive structure of the telescopic component 1, which can drive the telescopic shaft 11 to perform reciprocating telescopic motion, thereby realizing the swing of the side brush assembly 2.

[0056] In some embodiments, the first drive unit 12 includes the main body portion (non-telescopic rod portion) of the electric telescopic rod. Alternatively, the first drive unit 12 includes the cylinder body portion of a cylinder or hydraulic cylinder.

[0057] In some embodiments, the first drive unit 12 includes a push-pull electromagnet. The push-pull electromagnet is magnetically connected to the telescopic shaft 11, and by supplying power to the push-pull electromagnet, it can drive the telescopic shaft 11 to reciprocate and extend. Alternatively, the first drive unit 12 includes a rotary electromagnet. The rotary electromagnet is connected to the telescopic shaft 11 through a transmission mechanism, and by supplying power to the rotary electromagnet, it can rotate to drive the transmission mechanism, and based on the transmission mechanism, drive the telescopic shaft 11 to reciprocate and extend. Alternatively, the first drive unit 12 includes a motor, gears, and a connecting rod. The motor is connected to the telescopic shaft 11 through the gears and the connecting rod, and by driving the gears and the connecting rod, the motor drives the telescopic shaft 11 to reciprocate and extend.

[0058] like Figure 1 and Figure 2 As shown, in some embodiments, the telescopic shaft 11 is a magnetic telescopic shaft 11. The first driving unit 12 includes an electromagnetic coil 121. The electromagnetic coil 121 is magnetically connected to the telescopic shaft 11 and is used to drive the telescopic shaft 11 to extend and retract.

[0059] It is understandable that by magnetically connecting the electromagnetic coil 121 to the telescopic shaft 11, when current is passed through the electromagnetic coil 121, the electromagnetic coil 121 will generate a magnetic field, which will generate a magnetic force on the telescopic shaft 11, thereby pushing the telescopic shaft 11 away from the electromagnetic coil 121 or pulling it towards the electromagnetic coil 121, thus realizing the reciprocating telescopic motion of the telescopic shaft 11.

[0060] When current is passed through the electromagnetic coil 121, the direction of the magnetic field can be changed by altering the direction of the current. Therefore, reversing the direction of the current will change the direction of the magnetic field. Specifically, when current flows through the electromagnetic coil 121 in the first direction, the magnetic field generated by the electromagnetic coil 121 exerts a pushing force on the telescopic shaft 11, causing it to move away from the electromagnetic coil 121. When current flows through the electromagnetic coil 121 in the second direction, the magnetic field generated by the electromagnetic coil 121 exerts a pulling force on the telescopic shaft 11, causing it to move closer to the electromagnetic coil 121. The first and second directions are opposite.

[0061] Therefore, the magnetic field generated by the electromagnetic coil 121 drives the telescopic shaft 11 to extend and retract, thereby realizing the swing of the side brush assembly 2.

[0062] like Figure 1 and Figure 2As shown, in some embodiments, the first drive unit 12 further includes a permanent magnet 122. The permanent magnet 122 is magnetically connected to the telescopic shaft 11 and is used to lock the position of the telescopic shaft 11.

[0063] Understandably, the electromagnetic coil 121 can only provide the force for the telescopic shaft 11 to extend and retract, but cannot provide the force to hold the telescopic shaft 11 in place. The telescopic shaft 11 drives the side brush assembly 2 to swing, and the side brush 22 of the side brush assembly 2 needs to maintain its fixed position during the cleaning process. Therefore, a permanent magnet 122 is magnetically connected to the telescopic shaft 11, thereby using the permanent magnet 122 to lock the position of the telescopic shaft 11, so that the position of the side brush 22 remains fixed.

[0064] Specifically, the permanent magnet 122 can apply a force to the telescopic shaft 11 after the electromagnetic coil 121 extends it, thus keeping the telescopic shaft 11 in the extended position. The permanent magnet 122 can also apply a force to the telescopic shaft 11 after the electromagnetic coil 121 retracts it, thus keeping the telescopic shaft 11 in the retracted position. This allows the side brush assembly 2 to achieve position locking both before and after oscillation, ensuring effective cleaning.

[0065] In some embodiments, two permanent magnets 122 may be provided, and the two permanent magnets 122 are arranged opposite each other and spaced apart. The telescopic shaft 11 may be inserted between the two permanent magnets 122. The two permanent magnets 122 need only be able to lock the position of the telescopic shaft 11 in its extended and retracted states; this embodiment does not limit the spacing or magnetic pole distribution of the two permanent magnets 122.

[0066] In some embodiments, two electromagnetic coils 121 are spaced apart along a third direction. Two permanent magnets 122 are spaced apart along a fourth direction. The two permanent magnets 122 are located between the two electromagnetic coils 121.

[0067] It should be noted that the magnetic force exerted by the permanent magnet 122 on the telescopic shaft 11 is limited, allowing the side brush assembly 2 to change its state after being subjected to a force exceeding a certain magnitude. Specifically, when the telescopic shaft 11 is in the extended state, the side brush assembly 2 swings out of the space where the main body mechanism 3 is located. When the side brush assembly 2 collides forcefully with the wall / obstacle, it can swing back under the action of external force, thus being pushed back into the space where the main body mechanism 3 is located. At this time, the telescopic shaft 11 switches from the extended state to the retracted state. This protects the side brush assembly 2 from damage caused by excessive impact force when its position is fixed.

[0068] like Figure 1As shown, in some embodiments, the first drive unit 12 further includes a first housing 123. The first housing 123 is configured to be fixed to the main body mechanism 3. The electromagnetic coil 121 and the permanent magnet 122 are both disposed inside the first housing 123. One end of the telescopic shaft 11 passes through the first housing 123, and the other end is rotatably connected to the side brush assembly 2 outside the first housing 123.

[0069] It is understandable that the electromagnetic coil 121 and the permanent magnet 122 are built into the first housing 123 to provide dust protection and transmission protection, so as to prevent the transmission from being affected by excessive dust or particulate matter and causing transmission jamming. The first housing 123 has a through hole on one side, and the telescopic shaft 11 passes through the through hole, so that one end of the telescopic shaft 11 is located inside the housing, and the other end passes through the housing and is rotatably connected to the side brush assembly 2.

[0070] In some embodiments, the first housing 123 can be fixed to the main body 3 by means of fastener fixing, welding, bonding, heat fusion connection, etc.

[0071] like Figure 1 As shown, in some embodiments, the side brush assembly 2 includes a drive member 21 and a side brush 22. The drive member 21 is configured to be rotatably mounted on the main body mechanism 3. One end of the drive member 21 is connected to the telescopic shaft 11. The side brush 22 is rotatably connected to the other end of the drive member 21. The drive member 21 and the side brush 22 are drively connected for driving the side brush 22 to rotate.

[0072] Understandably, the drive component 21 drives the side brush 22 to rotate, thereby enabling the side brush 22 to clean the ground. The drive component 21 serves as both the drive mechanism for the side brush 22 and is rotatably connected to the main body 3, allowing it to swing under the action of the telescopic shaft 11. Since one end of the drive component 21 is connected to the telescopic shaft 11 and the other end is rotatably connected to the side brush 22, the position of the side brush 22 can move accordingly when the telescopic shaft 11 drives the telescopic component 21 to swing. Therefore, when the telescopic shaft 11 is in the retracted state, the side brush 22 can be entirely located below the main body 3; or, most of the side brush 22 can be located below the main body 3, with a small portion outside the space occupied by the main body 3. When the telescopic shaft 11 is in the extended state, the side brush 22 can be entirely located outside the space occupied by the main body 3; or, most of the side brush 22 can be located outside the space occupied by the main body 3, with a small portion below the main body 3.

[0073] In some embodiments, the main body 3 may be connected to multiple side brush assemblies 2. Each side brush assembly 2 may be connected to a telescopic shaft 11. Each telescopic shaft 11 independently drives the side brush assembly 2 to swing.

[0074] like Figure 3As shown, in some embodiments, the drive member 21 includes a second drive portion 211 and a transmission portion 212. The transmission portion 212 is drively connected between the second drive portion 211 and the side brush 22.

[0075] It is understandable that the second drive unit 211 drives the side brush 22 to rotate through the transmission unit 212, thereby enabling the side brush 22 to clean the ground.

[0076] In some embodiments, the second drive unit 211 may be a motor. The output shaft of the motor rotates and drives the side brush 22 to rotate via the transmission unit 212, so that the side brush 22 can clean the ground.

[0077] like Figure 4 As shown, in some embodiments, the transmission unit 212 includes a first synchronous pulley 2121, a second synchronous pulley 2122, and a synchronous belt 2123. The first synchronous pulley 2121 is drive-connected to the output shaft of the second drive unit 211. The second synchronous pulley 2122 is drive-connected to the rotating shaft of the side brush 22. The second synchronous pulley 2122 is spaced apart from the first synchronous pulley 2121. The synchronous belt 2123 is drive-connected between the first synchronous pulley 2121 and the second synchronous pulley 2122.

[0078] Understandably, the torque of the second drive unit 211 is transmitted to the side brush 22 using the first synchronous pulley 2121, the second synchronous pulley 2122, and the synchronous belt 2123, so that the side brush 22 can clean the floor. Based on the synchronous belt 2123 transmission method, compared with gearbox transmission, transmission noise can be reduced and the sound quality of the robot vacuum cleaner can be improved.

[0079] In some embodiments, the diameters of the first synchronizer wheel 2121 and the second synchronizer wheel 2122 are different. For example, the diameter of the first synchronizer wheel 2121 is smaller than the diameter of the second synchronizer wheel 2122. This allows for an increase in the rotational speed of the side brush 22, increasing its cleaning frequency and improving the cleaning effect.

[0080] like Figure 2 and Figure 3 As shown, in some embodiments, the drive member 21 further includes a second housing 213. The second housing 213 is configured to be rotatably mounted on the main body mechanism 3. A transmission part 212 is disposed within the second housing 213. A second drive part 211 is disposed on the upper surface of one end of the second housing 213. A side brush 22 is disposed on the lower surface of the other end of the second housing 213.

[0081] Understandably, the transmission unit 212 is housed within the second housing 213 to provide dust protection and transmission safeguards, preventing excessive dust or particulate matter from affecting the transmission and causing jamming. A through-hole is provided on the upper surface of one end of the second housing 213, through which the output shaft of the second drive unit 211 passes and connects to the second transmission unit 212 located within the second housing 213. A through-hole is also provided on the lower surface of the other end of the second housing 213, through which the rotation shaft of the side brush 22 passes and connects to the second transmission unit 212 located within the second housing 213.

[0082] Specifically, both the first synchronous pulley 2121 and the second synchronous pulley 2122 are rotatably mounted within the second housing 213. The synchronous belt 2123 is located within the second housing 213 and is sleeved between the first synchronous pulley 2121 and the second synchronous pulley 2122. The output shaft of the second drive unit 211 passes through a through-hole inside the second housing 213 and is coaxially connected to the first synchronous pulley 2121. The rotation shaft of the side brush 22 passes through a through-hole inside the second housing 213 and is coaxially connected to the second synchronous pulley 2122.

[0083] like Figure 2 and Figure 3 As shown, in some embodiments, the second housing 213 has a strip-shaped notch 214 at the end away from the side brush 22. The telescopic shaft 11 is connected to the connector 13. The connector 13 is slidably mounted within the strip-shaped notch 214.

[0084] It is understandable that a strip-shaped notch 214 is formed at the end of the second housing 213 away from the side brush 22, and the connector 13 of the telescopic shaft 11 is slidably disposed in the strip-shaped notch 214. When the telescopic shaft 11 extends or retracts, the connector 13 can slide in the strip-shaped notch 214, thereby realizing the degree of freedom of swing, so as to avoid the telescopic shaft 11 being stuck during the swing.

[0085] In some embodiments, the length of the strip notch 214 is adapted to the telescopic stroke of the telescopic shaft 11. For example, when the telescopic shaft 11 is in the extended state, the connector 13 slides to the first end of the strip notch 214; when the telescopic shaft 11 is in the retracted state, the connector 13 slides to the second end of the strip notch 214. Alternatively, the length of the strip notch 214 is greater than the telescopic stroke of the telescopic shaft 11. For example, when the telescopic shaft 11 is in the extended state, the connector 13 slides to a position close to and spaced apart from the first end of the strip notch 214; when the telescopic shaft 11 is in the retracted state, the connector 13 slides to a position close to and spaced apart from the second end of the strip notch 214.

[0086] like Figure 2 and Figure 3As shown, in some embodiments, the end of the connector 13 away from the telescopic shaft 11 extends through the strip notch 214 and is connected to the limiting member 14.

[0087] It is understandable that a limiting member 14 is provided on the connector 13 to prevent the connector 13 from falling out of the strip notch 214, thus ensuring a reliable connection between the telescopic shaft 11 and the second housing 213.

[0088] In some embodiments, the limiting member 14 may be a retaining ring.

[0089] In some embodiments, the size of the limiting member 14 is larger than the width of the strip notch 214. For example, the limiting member 14 is circular, and the diameter of the limiting member 14 is larger than the width of the strip notch 214, thereby preventing the connector 13 from falling out of the strip notch 214. For example, the limiting member 14 is square, and the side length of the limiting member 14 is larger than the width of the strip notch 214, thereby preventing the connector 13 from falling out of the strip notch 214.

[0090] like Figure 2 and Figure 3 As shown, in some embodiments, a swing shaft 215 is provided on the second housing 213. The swing shaft 215 is configured to be rotatably connected to the main body mechanism 3. The swing shaft 215 is located on the extension line of the axis of the strip notch 214.

[0091] Understandably, the second housing 213 is rotatably connected to the main body mechanism 3 via the swing shaft 215, and driven by the telescopic shaft 11, the second housing 213 swings along the swing shaft 215, thereby changing the position of the side brush 22. The swing shaft 215 is positioned on the extension line of the axis of the strip notch 214 to ensure that the connector 13 does not interfere with the swing of the second housing 213 and to prevent the swing from jamming.

[0092] In some embodiments, the swing shaft 215 is coaxially arranged with the output shaft of the second motor. Therefore, when the second housing 213 swings, the position of the second motor does not change, ensuring that the second motor does not interfere with the operation of other components of the sweeping robot.

[0093] like Figure 5 and Figure 6 As shown, according to a second aspect of this application, a robotic vacuum cleaner is provided, which includes the aforementioned side brush device. This robotic vacuum cleaner possesses all the beneficial effects of the aforementioned side brush device, which will not be elaborated further herein.
