Description

Technical Field

[0001] The present application relates to the field of robotics, and in particular to a cleaning robot. Background Art

[0002] Cleaning robots can replace manual labor and achieve automated cleaning. For example, pool cleaning robots can be used to clean pool walls. However, existing pool cleaning robots typically have cleaning brushes mounted between two track wheels. As the robot moves closely against the pool wall, the brushes cannot make contact with the pool wall, preventing it from cleaning the angles between the pool bottom and sidewalls, resulting in poor cleaning results. Utility Model Content

[0003] In view of this, the present application provides a cleaning robot to solve the problem that when the robot walks close to the side wall of the swimming pool, there are blind spots in cleaning, resulting in poor cleaning effect.

[0004] One embodiment of the present application provides a cleaning robot, which includes a cleaning body, a running mechanism, and a cleaning mechanism. The running mechanism includes a first running wheel assembly and a second running wheel assembly. The first running wheel assembly and the second running wheel assembly are respectively rotatably arranged on both sides of the cleaning body to drive the cleaning robot to move. The cleaning mechanism includes a first cleaning assembly and a second cleaning assembly. The first cleaning assembly is rotatably arranged on the cleaning body and is located between the first running wheel assembly and the second running wheel assembly. The second cleaning assembly is rotatably arranged on the outside of the first running wheel assembly and / or the second running wheel assembly.

[0005] In the above embodiment, a first cleaning assembly and a second cleaning assembly are provided on the cleaning body of the cleaning robot. The first cleaning assembly is disposed between the first and second running wheel assemblies, and the second cleaning assembly is disposed outside the first and / or second running wheel assemblies. Thus, when the cleaning robot travels closely against the sidewall of a swimming pool, driven by the first and / or second running wheel assemblies, the first cleaning assembly can clean the bottom wall of the pool, while the second cleaning assembly simultaneously cleans the sidewall of the pool and the angle between the bottom and sidewall of the pool, thereby reducing blind spots and improving cleaning efficiency.

[0006] In some embodiments of the present application, the first travel wheel assembly and the second travel wheel assembly each include a first travel wheel and a second travel wheel. The first travel wheel and the second travel wheel are spaced apart along the travel direction of the cleaning robot. The second cleaning assembly is connected to the outer side of the first travel wheel and / or the second travel wheel to drive the second cleaning assembly via the first travel wheel and / or the second travel wheel.

[0007] In the above embodiment, the walking mechanism of the cleaning robot includes two first walking wheels and two second walking wheels, and a second cleaning component is arranged on one side of the rotation axis of the first walking wheel and / or the second walking wheel. When the cleaning robot walks, the second cleaning component can rotate with the rotation of the first walking wheel and / or the second walking wheel, thereby effectively cleaning the area to be cleaned.

[0008] In some embodiments of the present application, the second cleaning assembly includes a connecting disk and a second cleaning brush disposed on the connecting disk. The second cleaning brush is fixedly connected to the first travel wheel and / or the second travel wheel via the connecting disk.

[0009] In the above embodiment, the second cleaning component is fixedly connected to the first traveling wheel and / or the second traveling wheel through a connecting plate, and different types of second cleaning components can be installed on the connecting plate, such as a hard cleaning brush, a soft cleaning brush or a dust suction port. If the second cleaning component is directly fixed to the first traveling wheel and / or the second traveling wheel, the cost of replacing the first traveling wheel and / or the second traveling wheel is high, and there is a problem of inconvenience in replacement.

[0010] In some embodiments of the present application, the second cleaning assembly includes a brush disc. The brush disc is connected to a connecting disc. A plurality of bristles are disposed on a side of the brush disc away from the connecting disc, along the axial direction of the brush disc's rotation. The bristles are spaced apart circumferentially along the rotational direction of the brush disc. The bristles extend away from the connecting disc, along the axial direction of the brush disc's rotation.

[0011] In the above embodiment, the second cleaning assembly includes a brush disc and a plurality of bristles. The bristles are arranged to have a specific length in the axial direction of the brush disc's rotation, allowing them to adapt to different surface types. This allows the cleaning robot to reach deep into crevices and cracks when cleaning sidewalls. Furthermore, the extended length of the bristles increases the contact area between the bristles and the surface being cleaned, improving cleaning effectiveness.

[0012] In some embodiments of the present application, the length of the bristles extending along the axial direction of rotation of the brush disc is 15-20 mm.

[0013] In the above embodiment, along the axial direction of the brush disc, the appropriate extension length of the bristles can avoid the cleaning effect being affected by bristles being too short, and can also avoid the resistance caused by bristles being too long, resulting in wear and breakage of the bristles.

[0014] In some embodiments of the present application, the second cleaning assembly is detachably connected to the first travel wheel assembly and / or the second travel wheel assembly.

[0015] In the above embodiment, the second cleaning assembly is detachably attached to the outer side of the first and / or second travel wheel assemblies, facilitating cleaning, maintenance, and replacement of the second cleaning assembly. Compared to a system where the second cleaning assembly is directly and detachably connected to the first and / or second travel wheels, the connecting plate simplifies replacement and maintenance of the second cleaning assembly, allowing users to easily remove and install the second cleaning assembly, extending the life of the cleaning robot.

[0016] In some embodiments of the present application, the cleaning robot further includes two drive motors, each first travel wheel is transmission-connected to a drive motor, and the first travel wheel is connected to the second travel wheel located on the same side of the cleaning body via a transmission belt.

[0017] In the above embodiment, the first travel wheels on both sides are each driven by a drive motor, which improves the maneuverability of the cleaning robot and facilitates turning and steering. The first travel wheel serves as the driving wheel, and the second travel wheel serves as the driven wheel, which can meet the driving requirements of the cleaning robot. The provision of a transmission belt enables the first and second travel wheels to move synchronously, thereby making the cleaning robot move more smoothly.

[0018] In some embodiments of the present application, the first traveling wheel is configured with an inner gear ring around its rotation direction. The output shaft of the driving motor is connected to a first gear, and the first gear meshes with the inner gear ring for transmission.

[0019] In the above embodiment, the drive motor drives the first gear to rotate, thereby driving the first travel wheel to rotate. The first gear and the inner ring gear constructed on the first travel wheel are engaged and transmitted, which can make the rotation direction of the first travel wheel the same as the rotation direction of the drive motor output shaft, and the second cleaning assembly is fixed to the outside of the first travel wheel. Therefore, the rotation direction of the second cleaning assembly is consistent with the rotation direction of the first travel wheel, which can reduce the reaction force of the ground on the second cleaning assembly and reduce the possibility of the second cleaning assembly getting stuck. At the same time, if the rotation direction of the second cleaning assembly is opposite to the rotation direction of the first travel wheel, the second cleaning assembly may push dirt to the area that has already been cleaned; therefore, the rotation direction of the second cleaning assembly is set to be consistent with that of the first travel wheel.

[0020] In some embodiments of the present application, the first cleaning assembly includes a first cleaning brush. At least one end of the first cleaning brush is provided with a second gear, which is meshed with the inner gear ring for transmission.

[0021] In the above embodiment, the first cleaning brush is driven by the meshing of the second gear and the inner gear ring of the first travel wheel. The rotation direction of the first cleaning brush is consistent with the rotation direction of the first travel wheel, which can reduce the reaction force of the ground on the first cleaning brush. At the same time, if the rotation direction of the first cleaning brush is opposite to that of the first travel wheel, the first cleaning brush may push dirt into the area that has already been cleaned, causing contamination. Therefore, the rotation direction of the first cleaning brush is set to be consistent with that of the first travel wheel.

[0022] In some embodiments of the present application, the first traveling wheel and the second traveling wheel are both configured with an outer gear ring on the outer circumferential surface, and the transmission belt is sleeved on the first traveling wheel and the second traveling wheel and meshes with the outer gear ring.

[0023] In the above embodiment, the first traveling wheel can be used as a driving wheel, and the second traveling wheel can be used as a driven wheel. The transmission belt is tensioned by the cooperation of the first traveling wheel and the second traveling wheel, thereby ensuring the stability of the cleaning robot during movement.

[0033] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0034] Here, the symbol “-” should be understood as including its endpoint values. For example, a length of A to B should be understood as being greater than or equal to A and less than or equal to B.

[0035] In the description of this application, it should be noted that the terms "inside" and "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on this application.

[0036] In addition, the terms “first” and “second” are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0037] As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0038] In the present application, the relatively fixed arrangement of the two does not mean that they cannot be disassembled, but is intended to mean that the relatively fixed two can move together when the cleaning robot is in use.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0040] An embodiment of the present application provides a cleaning robot, which includes a cleaning body, a running mechanism, and a cleaning mechanism. The running mechanism includes a first running wheel assembly and a second running wheel assembly. The first running wheel assembly and the second running wheel assembly are respectively rotatably arranged on both sides of the cleaning body to drive the cleaning robot to move. The cleaning mechanism includes a first cleaning assembly and a second cleaning assembly. The first cleaning assembly is rotatably arranged on the cleaning body and is located between the first running wheel assembly and the second running wheel assembly. The second cleaning assembly is rotatably arranged on the outside of the first running wheel assembly and / or the second running wheel assembly.

[0041] The cleaning robot's main cleaning body is equipped with a first cleaning assembly and a second cleaning assembly. The first cleaning assembly is positioned between the first and second running wheel assemblies, while the second cleaning assembly is positioned outside the first and / or second running wheel assemblies. This allows the robot to move closely against the pool's sidewalls, driven by the first and / or second running wheel assemblies. The first cleaning assembly cleans the pool's bottom wall, while the second cleaning assembly simultaneously cleans the pool's sidewalls and the angle between them, minimizing blind spots and improving cleaning effectiveness.

[0042] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features of the embodiments may be combined with each other.

[0043] See Figure 1 One embodiment of the present application provides a cleaning robot 100, which includes a cleaning body 1, a walking mechanism and a cleaning mechanism. The walking mechanism includes a first walking wheel assembly 201 and a second walking wheel assembly 202. The first walking wheel assembly 201 and the second walking wheel assembly 202 are respectively rotatably arranged on both sides of the cleaning body 1 to drive the cleaning robot 100 to move. The cleaning mechanism includes a first cleaning assembly 31 and a second cleaning assembly 32. The first cleaning assembly 31 is rotatably arranged on the cleaning body 1 and is located between the first walking wheel assembly 201 and the second walking wheel assembly 202. The second cleaning assembly 32 is rotatably arranged on the outside of the first walking wheel assembly 201 and / or the second walking wheel assembly 202.

[0044] The cleaning robot 100's cleaning body 1 is equipped with a first cleaning assembly 31 and a second cleaning assembly 32. The first cleaning assembly 31 is positioned between the first and second running wheel assemblies 201, 202, and the second cleaning assembly 32 is positioned outside the first and / or second running wheel assemblies 201, 202. This allows the cleaning robot 100 to move closely against the sidewalls of a swimming pool, driven by the first and / or second running wheel assemblies 201, 202. The first cleaning assembly 31 cleans the pool's bottom wall, while the second cleaning assembly 32 simultaneously cleans the pool's sidewalls and the angle between them, minimizing blind spots and improving cleaning effectiveness.

[0045] It can be understood that the first cleaning assembly 31 is arranged between the first traveling wheel assembly 201 and the second traveling wheel assembly 202. The between here refers to between the first traveling wheel assembly 201 and the second traveling wheel assembly 20 along the rotation axis of the first traveling wheel assembly 201 and / or the second traveling wheel assembly 202, and between the first traveling wheel assembly 201 and the second traveling wheel assembly 20.

[0046] It can be understood that since the first walking wheel assembly 201 and the second walking wheel assembly 202 are arranged on both sides of the cleaning body 1, and the second cleaning assembly 32 is arranged on the outside of the first walking wheel assembly 201 and / or the second walking wheel assembly 202, the outside here refers to the side of the first walking wheel assembly 201 and / or the second walking wheel assembly 202 that is in contact with the side wall of the swimming pool to be cleaned along the rotation axis of the first walking wheel assembly 201 or the second walking wheel assembly 202 when the cleaning robot 100 moves.

[0047] In some embodiments, see Figure 1 and Figure 2 The first travel wheel assembly 201 and the second travel wheel assembly 202 each include a first travel wheel 21 and a second travel wheel 22. The first travel wheel 21 and the second travel wheel 22 are spaced apart along the travel direction of the cleaning robot 100. The second cleaning assembly 32 is connected to the outer side surface of the first travel wheel 21 and / or the second travel wheel 22 to drive the second cleaning assembly 32 via the first travel wheel 21 and / or the second travel wheel 22.

[0048] The walking mechanism of the cleaning robot 100 includes two first walking wheels 21 and two second walking wheels 22. A second cleaning component 32 is arranged on one side of the rotation axis of the first walking wheel 21 and / or the second walking wheel 22. When the cleaning robot 100 walks, the second cleaning component 32 can rotate with the rotation of the first walking wheel 21 and / or the second walking wheel 22, thereby effectively cleaning the area to be cleaned.

[0049] In some embodiments, the second cleaning assembly 32 can be arranged on the outside of a first walking wheel 21, or on the outside of a second walking wheel 22, or on the outside of each first walking wheel 21 and the second walking wheel 22, or on the outside of the first walking wheel 21 on one side and the outside of the second walking wheel 22 on the other side.

[0050] In some embodiments, see Figure 3 and Figure 4 The second cleaning assembly 32 includes a connecting disk 321 and a second cleaning brush 322 provided on the connecting disk 321. The second cleaning brush 322 is fixedly connected to the first travel wheel 21 and / or the second travel wheel 22 through the connecting disk 321.

[0051] The second cleaning component 32 is fixedly connected to the first traveling wheel 21 and / or the second traveling wheel 22 through the connecting disk 321. Different types of second cleaning components 32 can be installed on the connecting disk 321, such as a hard cleaning brush, a soft cleaning brush or a dust suction port. If the second cleaning component 32 is directly fixed to the first traveling wheel 21 and / or the second traveling wheel 22, the cost of replacing the first traveling wheel 21 and / or the second traveling wheel 22 is high, and there is a problem of inconvenience in replacement.

[0052] In some embodiments, the second cleaning assembly 32 includes a brush disc 3221. The brush disc 3221 is connected to a connecting disc 321. A plurality of bristles 3222 are provided on a side of the brush disc 3221 away from the connecting disc 321, along the axis of rotation of the brush disc 3221. The bristles 3222 are spaced apart around the circumference of the rotation of the brush disc 3221. Along the axis of rotation of the brush disc 3221, the bristles 3222 extend away from the connecting disc 321.

[0053] The second cleaning assembly 32 includes a brush disc 3221 and a plurality of bristles 3222. The bristles 3222 are arranged to a certain length along the axis of the brush disc 3221's rotation, allowing them to adapt to different surface types. This allows the bristles 3222 to reach deep into crevices when the cleaning robot 100 is cleaning a sidewall. Furthermore, the extended length of the bristles 3222 increases the contact area between the bristles 3222 and the surface being cleaned, improving cleaning effectiveness.

[0054] In some embodiments, the brush plate 3221 is disc-shaped.

[0055] In some embodiments, the bristles 3222 extend to a length of 15-20 mm along the axial direction of rotation of the brush disc 3221 .

[0056] Along the axial direction of the rotation of the brush disc 3221, the appropriate extension length of the bristles can prevent the bristles 3222 from being too short and affecting the cleaning effect, and can also prevent the bristles 3222 from being too long and generating resistance and causing the bristles 3222 to be worn and broken.

[0057] In some embodiments, see Figure 4 The second cleaning assembly 32 is detachably connected to the first travel wheel assembly 201 and / or the second travel wheel assembly 202 .

[0058] The second cleaning assembly 32 is detachably mounted to the outer side of the first travel wheel assembly 201 and / or the second travel wheel assembly 202, facilitating cleaning, maintenance, and replacement of the second cleaning assembly 32. Compared to a case where the second cleaning assembly 32 is directly and detachably connected to the first travel wheel 21 and / or the second travel wheel 22, the connecting plate 321 simplifies replacement and maintenance of the second cleaning assembly 32, allowing users to easily remove and install the second cleaning assembly 32, thereby extending the service life of the cleaning robot 100.

[0059] In some embodiments, the second cleaning assembly 32 includes a connecting disk 321 and a second cleaning brush 322 disposed on the connecting disk 321. The connecting disk 321 has a first connecting surface 3211 and a second connecting surface 3212 disposed opposite to each other. The first running wheel 21 and / or the second running wheel 22 are detachably connected to the first connecting surface 3211 so as to fix the first running wheel 21 and / or the second running wheel 22 to the connecting disk 321. The second cleaning brush 322 is detachably connected to the second connecting surface 3212 so as to fix the second cleaning brush 322 to the connecting disk 321. In this way, the second cleaning brush 322 can be easily installed and removed, and the rotation of the second cleaning brush 322 can be synchronized with the rotation of the first running wheel 21 and / or the second running wheel 22.

[0060] In some embodiments, the second cleaning brush 322 includes a disc-shaped brush disc 3221, and along the axial direction of rotation of the brush disc 3221, a plurality of bristles 3222 are provided on the side of the brush disc 3221 away from the connecting disc 321, that is, the plurality of bristles 3222 are arranged on the outside of the first walking wheel assembly 201 and / or the second walking wheel assembly 202.

[0061] In some embodiments, the second cleaning brush 322 can be arranged only on the outside of the rotation axis of the first walking wheel 21, or only on the outside of the rotation axis of the second walking wheel 22; it can also be arranged on the outside of the rotation axis of both the first walking wheel 21 and the second walking wheel 22 to improve the cleaning effect.

[0062] Taking the example of the second cleaning brush 322 being arranged outside the rotation axis of the first running wheel 21, in some embodiments, a detachable connection can be achieved between the connecting plate 321 and the first running wheel 21, and between the connecting plate 321 and the second cleaning brush 322, via a snap-fit ​​structure. The advantage of the snap-fit ​​structure is that it is easy to assemble and disassemble, and can be completed by "pressing" and "pulling". Based on the assembly and disassembly of the snap-fit ​​structure, the connecting plate 321 should be made of a material with a certain hardness, such as hard plastic, which can provide relatively clear tactile feedback, so that the connecting plate 321 can be installed on the first running wheel 21 in a "blind installation" manner. As a cleaning component, the second cleaning brush 322 is generally made of a softer material, so it is not directly assembled and disassembled with the first running wheel 21, but is assembled and disassembled with the connecting plate 321. Of course, screws can also be used to achieve assembly and disassembly between the connecting plate 321 and the first running wheel 21, making the connection strength between the connecting plate 321 and the first running wheel 21 higher.

[0063] In some embodiments, see Figure 5 The cleaning robot 100 also includes two drive motors 41 , each first travel wheel 21 is transmission-connected to a drive motor 41 , and the first travel wheel 21 is connected to the second travel wheel 22 located on the same side of the cleaning body 1 through a transmission belt 23 .

[0064] The first running wheels 21 on either side are each driven by a drive motor 41, which improves the maneuverability of the cleaning robot 100 and facilitates U-turns and steering. The first running wheels 21 serve as driving wheels, and the second running wheels 22 serve as driven wheels, which can meet the driving requirements of the cleaning robot 100. The provision of the transmission belt 23 enables the first running wheels 21 and the second running wheels 22 to move synchronously, thereby making the cleaning robot 100 move more smoothly.

[0065] In some embodiments, see Figure 2 and Figure 6 The first traveling wheel 21 is configured with an inner gear ring 211 around its rotation direction. The output shaft of the driving motor 41 is connected to the first gear 42, and the first gear 42 is meshed with the inner gear ring 211 for transmission.

[0066] The drive motor 41 drives the first gear 42 to rotate, thereby driving the first travel wheel 21 to rotate. The first gear 42 and the inner ring gear 211 constructed on the first travel wheel 21 are engaged and transmitted, which can make the rotation direction of the first travel wheel 21 the same as the rotation direction of the output shaft of the drive motor 41. The second cleaning assembly 32 is fixed to the outside of the first travel wheel 21. Therefore, the rotation direction of the second cleaning assembly 32 is consistent with the rotation direction of the first travel wheel 21, which can reduce the reaction force of the ground on the second cleaning assembly 32 and reduce the possibility of the second cleaning assembly 32 being stuck during rotation. At the same time, if the rotation direction of the second cleaning assembly 32 is opposite to the rotation direction of the first travel wheel 21, the second cleaning assembly 32 may push dirt to the area that has already been cleaned; therefore, the rotation direction of the second cleaning assembly 32 is set to be consistent with the first travel wheel 21.

[0067] In some embodiments, see Figure 5 The first cleaning assembly 31 includes a first cleaning brush 311. A second gear 312 is provided at at least one end of the first cleaning brush 311, and the second gear 312 is meshed with the inner gear ring 211 for transmission.

[0068] The first cleaning brush 311 is driven by meshing with the inner gear ring 211 of the first travel wheel 21 via the second gear 312. The rotation direction of the first cleaning brush 311 is consistent with the rotation direction of the first travel wheel 21, which can reduce the reaction force of the ground on the first cleaning brush 311. At the same time, if the first cleaning brush 311 rotates in the opposite direction of the first travel wheel 21, the first cleaning brush 311 may push dirt into the cleaned area, causing contamination. Therefore, the rotation direction of the first cleaning brush 311 is set to be consistent with the rotation direction of the first travel wheel 21.

[0069] In some embodiments, the first cleaning brush 311 includes a brush barrel 3111 and a plurality of roller brush bristles 3112. The rotation axis of the brush barrel 3111 is parallel to the rotation axis of the first travel wheel 21. The plurality of roller brush bristles 3112 are spaced apart on the outer circumference of the first travel wheel 21 along the axial direction and circumferential direction of the brush barrel 3111.

[0070] In some embodiments, the first and second traveling wheels 21 and 22 are both configured with outer gear rings 212 on their outer circumferential surfaces, and the transmission belt 23 is sleeved on the first and second traveling wheels 21 and 22 and meshes with the outer gear rings 212 .

[0071] The first traveling wheel 21 can be used as a driving wheel, and the second traveling wheel 22 can be used as a driven wheel. The transmission belt 23 is tensioned by the cooperation of the first traveling wheel 21 and the second traveling wheel 22, thereby ensuring the stability of the cleaning robot 100 when moving.

[0072] In addition, those skilled in the art should recognize that the above embodiments are merely intended to illustrate the present application and are not intended to limit the present application. As long as they are within the spirit of the present application, appropriate changes and modifications to the above embodiments are within the scope of disclosure of the present application.
