[0040] The exemplary embodiment of the present disclosure first provides a cleaning brush assembly 100. As shown in Figures 1 and 2, the cleaning brush assembly 100 includes a bracket 10, a drive module 20, and a side brush module 30. The drive module 20 is provided on the bracket 10, and the drive module 20 has an output shaft 201; the side brush module 30 includes a first transmission member 31 and a side brush 32. The first transmission member 31 is connected to the bracket 10, and the first transmission member 31 cooperates with the drive module 20 to drive the first transmission member 31 through the drive module. The first transmission member 31 has a first transmission shaft 301. The first transmission shaft 301 and the output shaft 201 of the drive module 20 are not parallel. The side brush 32 is connected to the first transmission shaft 301.

[0041] The cleaning brush assembly 100 provided in the embodiment of the present disclosure includes a bracket 10, a drive module 20 and a side brush module 30. The drive module 20 is arranged on the bracket 10. The side brush module 30 includes a first transmission member 31 and a side brush 32. The first transmission member 31 is arranged on the bracket 10. The side brush 32 is connected to the first transmission member 31. The drive module 20 drives the first transmission member 31 to drive the side brush 32 to rotate. The first transmission shaft 301 of the first transmission member 31 and the output shaft 201 of the drive module 20 are not parallel, so that the side brush 32 is in an inclined state during operation. The side brush 32 in an inclined state can gather the cleaning objects in one direction, thereby improving the ability of the cleaning robot to gather and collect the cleaning objects.

[0042] The following describes in detail the various parts of the cleaning brush assembly 100 provided in the embodiment of the present disclosure:

[0043] The side brush module 30 includes a first transmission member 31 and a side brush 32. The first transmission member 31 is connected to the bracket 10. The side brush 32 is connected to the first transmission member 31. The first transmission member 31 cooperates with the drive module 20. The drive module 20 drives the first transmission member 31 to rotate. When the first transmission member 31 rotates, the side brush 32 is also rotated. The first transmission member 31 has a first transmission shaft 301. The first transmission shaft 301 extends through the bracket 10. Driven by the drive module 20, the first transmission member 31 rotates along the first transmission shaft 301.

[0044] The drive module 20 includes a drive motor 21 and a second transmission member 22. The drive motor 21 has a drive shaft. The second transmission member 22 is connected to the drive motor 21. The drive motor 21 is capable of driving the second transmission member 22 to rotate. An output shaft 201 is provided on the second transmission member 22. The second transmission member 22 can rotate about the output shaft 201. The output shaft 201 is parallel to the drive shaft.

[0045] The first transmission member 31 includes a first gear 311, and the second transmission member 22 includes a second gear 221. The first gear 311 and the second gear 221 are meshed. The gear shaft of the first gear 311 forms the first transmission shaft 301, and the gear shaft of the second gear 221 forms the output shaft 201. The gear shaft of the first gear 311 is passed through the bracket 10, and the end of the gear shaft of the first gear 311 is connected to the side brush 32. The second gear 221 is installed on the bracket 10, and the gear shaft of the second gear 221 is connected to the drive shaft of the drive motor 21. For example, the gear shaft of the second gear 221 is connected to the drive shaft of the drive motor 21 through a device such as a coupling.

[0046] It will be appreciated that, in the disclosed embodiment, in order to effectively control the rotational speed of the first gear 311 and change the transmission ratio, the second transmission member 22 may further include at least one transmission gear 222. The transmission gear 222 is connected to the bracket 10 and is disposed between the second gear 221 and the drive motor 21. The transmission gear 222 is used to transmit the power output by the drive motor 21 to the second gear 221. The gear shaft of the transmission gear 222 is parallel to the gear shaft of the second gear 221.

[0047] For example, the second transmission member 22 may include a transmission gear 222. The transmission gear 222 is a third gear. The third gear is provided on the bracket 10, and the gear shaft of the third gear is connected to the drive shaft of the drive motor 21, and the third gear is meshed with the second gear 221. Alternatively, the second transmission member 22 may include two transmission gears 222. The two transmission gears 222 may be a third gear and a fourth gear. The third gear is provided on the bracket 10, and the gear shaft of the third gear is connected to the drive shaft of the drive motor 21, and the fourth gear is provided on the bracket 10, and the fourth gear is meshed with the third gear and the second gear 221 respectively.

[0048] In a feasible embodiment of the present disclosure, the first gear 311 is a helical gear, and the second gear 221 is a spur gear. The gear shaft of the second gear 221 is parallel to the drive shaft of the drive motor 21. A first preset angle is formed between the gear shaft of the first gear 311 and the gear shaft of the second gear 221. In the first gear 311, the angle between the gear teeth and the gear shaft is also the first preset angle. This first preset angle ensures meshing of the helical gear and the spur gear, preventing interference between the first gear 311 and the second gear 221.

[0049] The first gear 311 is rotatable relative to the bracket 10. For example, the bracket 10 is provided with a first mounting hole, through which the gear shaft of the first gear 311 is inserted. The first mounting hole is an inclined hole. The second gear 221 is rotatable relative to the bracket 10. For example, the bracket 10 is provided with a second mounting hole, through which the gear shaft of the second gear 221 is inserted. The second mounting hole is a straight hole.

[0050] On this basis, when the second transmission member 22 further includes a transmission gear 222, the transmission gear 222 is a spur gear, and the gear axis of the transmission gear 222 is parallel to the gear axis of the second gear 221. The transmission gear 222 is mounted on the bracket 10 and can rotate relative to the bracket 10. For example, the bracket 10 is provided with a third mounting hole, and the gear axis of the transmission gear 222 is inserted into the third mounting hole. The third mounting hole is a straight hole.

[0051] In another possible embodiment of the present disclosure, the first gear 311 is a spur gear, and the second gear 221 is a helical gear. The gear shaft of the second gear 221 is parallel to the drive shaft of the drive motor 21, and a first preset angle is formed between the gear shaft of the first gear 311 and the gear shaft of the second gear 221. The angle between the gear teeth of the second gear 221 and the gear shaft is also the first preset angle. This first preset angle ensures meshing between the helical and spur gears, preventing interference between the first gear 311 and the second gear 221.

[0052] The first gear 311 is rotatable relative to the bracket 10. For example, the bracket 10 is provided with a first mounting hole, through which the gear shaft of the first gear 311 is inserted. The first mounting hole is an inclined hole. The second gear 221 is rotatable relative to the bracket 10. For example, the bracket 10 is provided with a second mounting hole, through which the gear shaft of the second gear 221 is inserted. The second mounting hole is a straight hole.

[0053] On this basis, when the second transmission member 22 further includes a transmission gear 222, the transmission gear 222 is a helical gear, and the gear axis of the transmission gear 222 is parallel to the gear axis of the second gear 221. The transmission gear 222 is mounted on the bracket 10 and can rotate relative to the bracket 10. For example, the bracket 10 is provided with a third mounting hole, and the gear axis of the transmission gear 222 is inserted into the third mounting hole. The third mounting hole is a straight hole.

[0054] It is worth noting that in other feasible embodiments of the present disclosure, both the first gear 311 and the second gear 221 can be helical gears. The angle between the teeth of the first gear 311 and the gear shaft is a first bevel angle, and the angle between the teeth of the second gear 221 and the gear shaft is a second bevel angle. The difference between the first bevel angle and the second bevel angle is a first predetermined angle. Based on this, the transmission gear 222 is a helical gear, and the angle between the teeth of the transmission gear 222 and the gear shaft is the second bevel angle.

[0055] Of course, in actual applications, the first transmission member 31 and the second transmission member 22 in the disclosed embodiment may also be belt transmission members or chain transmission members. For example, the first transmission member 31 includes a first pulley, and the second transmission member 22 includes a second pulley. A transmission belt is mounted on the first and second pulleys. The drive motor 21 outputs power to rotate the second pulley, which then transmits the power to the first pulley via the transmission belt. The first transmission shaft 301 of the first pulley and the output shaft 201 of the second pulley are not parallel.

[0056] In the embodiment of the present disclosure, the first transmission shaft 301 of the first transmission member 31 is an axis passing through the rotation axis of the first transmission member 31. The gear shaft of the first gear 311 is an axis passing through the rotation axis of the first gear 311. The gear shaft in the first gear 311 can be integrally formed with the gear body, or the gear shaft and the gear body are separate structures, and the gear shaft passes through the axis of the gear body. The gear shaft of the second gear 221 is an axis passing through the rotation axis of the second gear 221. The gear shaft in the second gear 221 can be integrally formed with the gear body, or the gear shaft and the gear body are separate structures, and the gear shaft passes through the axis of the gear body. The gear shaft of the transmission gear 222 is an axis passing through the rotation axis of the transmission shaft, and the gear shaft in the transmission gear 222 can be integrally formed with the gear body, or the gear shaft and the gear body are separate structures, and the gear shaft passes through the axis of the gear body.

[0057] The side brush 32 is connected to the gear shaft of the first gear 311. The gear shaft of the first gear 311 is tilted, so the side brush 32 is also tilted. The tilted side brush 32 forms a preset angle with the ground when cleaning, which improves the side brush 32's ability to gather cleaned objects during cleaning.

[0058] The side brush 32 may include a brush body 321 and a plurality of brush branches 322. The brush body 321 is connected to the first transmission shaft 301. The plurality of brush branches 322 are connected to the brush body 321, and the ends of the plurality of brush branches 322 facing away from the brush body 321 are located in the same predetermined plane, which is perpendicular to the first transmission shaft 301.

[0059] The brush body 321 may be circular or hemispherical, and the plurality of brush branches 322 are distributed along the circumference of the brush body 321. The plurality of brush branches 322 may be evenly distributed on the brush body 321, or the plurality of brush branches 322 may be unevenly distributed on the brush body 321, which is not specifically limited in the embodiment of the present disclosure.

[0060] The brush branch 322 has a flexible brush segment at one end away from the brush body 321, and the flexible brush segment is used for cleaning. For example, the brush branch 322 may include a connecting segment and a flexible brush segment, one end of the connecting segment is connected to the brush body 321, and the other end of the connecting segment is connected to the flexible brush segment.

[0061] It should be noted that the phrase "the ends of the multiple brush branches 322 facing away from the brush body 321 are located in the same preset plane" in the disclosed embodiment means that, in the initial state, the ends of the multiple brush branches 322 facing away from the brush body 321 are located in the same preset plane. Alternatively, it can be understood that the surface of the brush body 321 facing away from the first transmission member 31 is perpendicular to the first transmission shaft 301, and the plane on which the ends of the multiple brush branches 322 facing away from the brush body 321 lie is parallel to the surface of the brush body 321 facing away from the first transmission member 31.

[0062] Optionally, the angle between the first transmission shaft 301 and the output shaft 201 can be 6-8 degrees. Based on this, the angle between the preset plane formed by the multiple brush branches 322 and the ground is also 6-8 degrees. By setting the angle between the first transmission shaft 301 and the output shaft 201 to 6-8 degrees, the angle between the side brush 32 and the ground is maintained at 6-8 degrees, which helps the side brush 32 collect cleaned material.

[0063] The bracket 10 is used to mount the drive module 20 and the side brush module 30. The bracket 10 may include a first panel 11 and a second panel 12. The first panel 11 and the second panel 12 are disposed opposite each other, and a storage space is formed between the first panel 11 and the second panel 12. The first transmission member 31 and the second transmission member 22 are disposed within the storage space. The drive motor 21 is disposed on the side of the second panel 12 facing away from the first panel 11.

[0064] The first transmission member 31 and the second transmission member 22 are connected to the first panel 11, and the output shaft 201 is arranged perpendicular to the first panel 11. The drive motor 21 is arranged on the side of the second panel 12 facing away from the first panel 11, and the drive shaft of the drive motor 21 passes through the second panel 12 and extends into the accommodating space, and the drive shaft is perpendicular to the second panel 12.

[0065] A first mounting hole is provided on the first panel 11. The first mounting hole is an inclined hole, that is, the axis of the first mounting hole is not perpendicular to the first panel 11. The first transmission shaft 301 of the first transmission member 31 is provided through the first mounting hole, and the first transmission shaft 301 is capable of rotating within the first mounting hole. The first transmission shaft 301 can be directly provided through the first mounting hole, or a bearing can be provided in the first mounting hole, and the first transmission shaft 301 is installed in the bearing. When the first transmission member 31 includes a first gear 311, the gear shaft of the first gear 311 is installed in the first mounting hole.

[0066] The first panel 11 is also provided with a second mounting hole. This second mounting hole is a straight hole, that is, its axis is perpendicular to the first panel 11. The output shaft 201 of the second transmission member 22 is inserted into the second mounting hole and is rotatable within the second mounting hole. The output shaft 201 can be inserted directly into the second mounting hole, or a bearing can be provided within the second mounting hole and mounted therein. If the second transmission member 22 includes a second gear 221, the second gear 221 is mounted in the second mounting hole.

[0067] In the embodiment of the present disclosure, the first mounting hole is set as an inclined hole, and the second mounting hole is set as a straight hole. The inclined first mounting hole ensures that the first transmission shaft 301 of the first transmission member 31 is inclined, and thus the side brush 32 is set at an angle, which is conducive to the gathering and collection of the cleaned objects. The inclined second mounting hole reduces the production difficulty and cost (the processing difficulty and cost of processing a straight hole on the first panel 11 are lower than the processing difficulty and cost of processing an inclined hole). In addition, the second mounting hole is a straight hole, which can reduce the space occupied by the second transmission member 22 in the vertical direction, which is conducive to improving the rationality of the layout of the cleaning robot.

[0068] When the second transmission member 22 further includes at least one transmission gear 222, at least one third mounting hole may be provided on the first panel 11. The third mounting hole is a straight hole, that is, the third mounting hole is perpendicular to the first panel 11. The gear shaft of the transmission gear 222 is inserted through the third mounting hole. The gear shaft of the transmission gear 222 may be directly inserted through the third mounting hole, or a bearing may be provided in the third mounting hole, and the gear shaft of the transmission gear 222 may be mounted in the bearing.

[0069] By setting the gear shafts of the second gear 221 and the transmission gear 222 to be perpendicular to the first panel 11, and setting the gear shaft of the first gear 311 to be an inclined axis, there is only one inclined hole on the first panel 11, which not only meets the inclination requirement of the side brush 32, but also effectively ensures the convenience of processing the first panel 11 and the utilization rate of the internal space of the cleaning robot.

[0070] The second panel 12 is arranged parallel to the first panel 11, forming a storage space between the first and second panels 11, 12. The first and second panels 11, 12 can be connected by a connecting arm. One end of the connecting arm is connected to the first panel 11, and the other end of the connecting arm is connected to the second panel 12. The connecting arm is located on one side of the bracket 10, and the other side of the bracket 10 forms an opening.

[0071] The cleaning brush assembly 100 is mounted on the housing of the cleaning robot. The housing has a bottom plate that faces the ground when the cleaning robot is in operation. The first panel 11 is parallel to the bottom plate, or the first surface can be embedded in the bottom plate. Specifically, the first transmission shaft 301 of the first transmission member 31 is arranged at an angle to the bottom plate, while the drive shaft of the drive motor 21 and the output shaft 201 of the second transmission member 22 are arranged perpendicular to the bottom plate.

[0072] In one feasible embodiment, the first panel 11 is positioned within the housing, with the first surface parallel to the bottom plate. Furthermore, the bottom plate is provided with a through-hole for mounting the side brush 32. The first transmission shaft 301 extends through the through-hole, which may be an inclined hole (non-perpendicular to the first panel 11).

[0073] In another feasible embodiment, the first panel 11 is embedded in the bottom plate. The bottom plate is provided with a receiving area, the receiving area is provided with a receiving hole, the first panel 11 is disposed in the receiving hole, and the first panel 11 and the bottom plate are connected. For example, the first panel 11 and the bottom plate can be connected by a snap connection, or the first panel 11 and the bottom plate can be connected by adhesive.

[0074] The first panel 11 is arranged parallel to the base plate. Thus, the gear axes of the second gear 221 and the transmission gear 222 are both arranged perpendicular to the base plate. Because the gears are small along their axes, this arrangement of the second gear 221 and the transmission gear 222 reduces the size of the gears in the height direction of the cleaning robot, thereby improving the compactness of the cleaning robot.

[0080] The housing can include a top plate, a bottom plate, and side plates. The top and bottom plates are positioned opposite each other, with the side plates connecting them and forming a housing cavity between them. When the cleaning robot is in operation, the bottom plate faces the bottom surface. The walking assembly, mopping assembly, and cleaning brush assembly 100 are located on the bottom plate. The collection assembly can be located in the housing cavity, and the control assembly can be located on the top or side plates.

[0081] The collection assembly may include a dust box and a dust collection unit. The dust box is disposed within the accommodating chamber and is used to collect cleaned material. An opening may be provided on the base plate, communicating with the dust box, through which cleaned material enters the dust box. The dust collection unit is in communication with the dust box and is used to draw cleaned material into the dust box. A filter may be disposed between the dust box and the dust collection unit to prevent foreign matter from entering the dust collection unit.

[0082] The travel assembly may include a steering wheel and driven wheels. The steering wheel is mounted on the base plate and is used to drive the cleaning robot and control its direction of movement. The driven wheel is also mounted on the base plate and is used to reduce friction between the cleaning robot and the ground. In practical applications, the travel assembly may also take other forms. For example, the travel assembly may be tracked, etc., but the disclosed embodiments are not limited thereto.

[0083] The control component may include a control module and a detection module. The detection module may include radar, a camera, a speed sensor, a photoelectric sensor, a gyroscope, and a contact sensor. The detection module detects the surrounding scene and the cleaning robot's own status. The control module is used to control the cleaning robot based on the signals detected by the detection module.

[0084] Furthermore, the control component may further include a communication module. The communication module is connected to the control module and is used to connect to network equipment or a control terminal. The communication module may include a WiFi module, a Bluetooth module, an infrared communication module, or a near-field communication module.

[0085] The cleaning brush assembly 100 is mounted on the housing, with the first panel 11 parallel to the bottom plate, or the first panel 11 can be embedded in the bottom plate. Specifically, the first transmission shaft 301 of the first transmission member 31 is tilted relative to the bottom plate, while the drive shaft of the drive motor 21 and the output shaft 201 of the second transmission member 22 are perpendicular to the bottom plate.

[0086] In one feasible embodiment, the first panel 11 is positioned within the housing, with the first surface parallel to the bottom plate. Furthermore, the bottom plate is provided with a through-hole for mounting the side brush 32. The first transmission shaft 301 extends through the through-hole, which may be an inclined hole (non-perpendicular to the first panel 11).

[0087] In another feasible embodiment, the first panel 11 is embedded in the bottom plate. The bottom plate is provided with a receiving area, the receiving area is provided with a receiving hole, the first panel 11 is disposed in the receiving hole, and the first panel 11 and the bottom plate are connected. For example, the first panel 11 and the bottom plate can be connected by a snap connection, or the first panel 11 and the bottom plate can be connected by adhesive.

[0088] The first panel 11 is arranged parallel to the base plate. Thus, the gear axes of the second gear 221 and the transmission gear 222 are both arranged perpendicular to the base plate. Because the gears are small along their axes, this arrangement of the second gear 221 and the transmission gear 222 reduces the size of the gears in the height direction of the cleaning robot, thereby improving the compactness of the cleaning robot.

[0089] In some application scenarios (for example, cleaning under beds or cabinets), the height of the cleaning robot needs to be effectively controlled due to the limited height of the working environment. In the disclosed embodiment, by arranging the gear shafts of most of the multiple gears perpendicular to the base, the height of the cleaning robot can be reduced, making cleaning easier.

[0090] The cleaning robot 1000 provided in the embodiment of the present disclosure includes a cleaning brush assembly 100. In the cleaning brush assembly 100, the driving module 20 is provided on the bracket 10. The side brush module 30 includes a first transmission member 31 and a side brush 32.

The driving module 20 drives the first transmission member 31 to drive the side brush 32 to rotate. The first transmission shaft 301 of the first transmission member 31 and the output shaft 201 of the driving module 20 are not parallel, so that when working, the side brush 32 is in an inclined state. The inclined side brush 32 can gather the cleaned objects in one direction, thereby improving the ability of the cleaning robot 1000 to gather and collect the cleaned objects.
