[0042] The exemplary embodiment of the present invention relates first to a set of cleaning brushes 100. As shown in [Fig. 1] and [Fig. 2], the set of cleaning brushes 100 comprises a support 10, a drive module 20 and a side brush module 30. The drive module 20 is located in the support 10 and the drive module 20 has an output shaft 201. The side brush module 30 comprises a first transmission element 31 and a side brush 32. The first transmission element 31 is connected to the support 10, and the first transmission element 31 and the drive module 20 are matched to drive the first transmission element 31 via the drive module. The first transmission element 31 has a first transmission shaft 301. The output shaft 201 and the first transmission shaft 301 are not parallel, and the side brush 32 is connected to the first transmission shaft 301.

[0043] The embodiment of the present invention relates to a cleaning brush assembly 100, comprising a support 10, a drive module 20 and a side brush module 30. The drive module 20 is located in the support 10, the side brush module 30 comprises a first transmission element 31 and a side brush 32, the first transmission element 31 is located in the support 10, the side brush 32 is connected to the first transmission element 31. The drive module 20 drives the first transmission element 31 to drive the rotation of the side brush 32.The first transmission shaft 301 of the first transmission element 31 and the output shaft 201 of the drive module 20 are not parallel. Thus, the side brush 32 is inclined during operation, and the side brush 32 can gather cleaning objects in one direction, thereby improving the cleaning robot's ability to gather and collect cleaning objects.

[0044] Each part of the cleaning brush assembly 100 provided in the embodiment of the present invention will be described in detail below:

[0045] The side brush module 30 comprises a first transmission element 31 and a side brush 32. The first transmission element 31 is connected to the support 10, the side brush 32 is connected to the first transmission element 31, the first transmission element 31 is adapted to the drive module 20, the first transmission element 31 is driven to rotate through the drive module 20, and the side brush 32 is driven to rotate when the first transmission element 31 rotates. The first transmission element 31 has a first drive shaft 301; the first drive shaft 301 passes through the support 10, and the first transmission element 31 rotates along the first drive shaft 301 under the drive of the drive module 20.

[0046] The drive module 20 comprises a drive motor 21 and a second transmission element 22, and the drive motor 21 has a drive shaft; the second transmission element 22 is connected to the drive motor 21, the drive motor 21 can drive the second transmission element 22 to rotate, the output shaft 201 is located on the second transmission element 22, the second transmission element 22 can rotate around the output shaft 201 and the output shaft 201 is parallel to the drive shaft.

[0047] The first transmission element 31 comprises a first gear 311. The second transmission element 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 a first transmission shaft 301 and the gear shaft of the second gear 221 forms an output shaft 201. The gear shaft of the first gear 311 passes through the support 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 in the support 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 by a device such as a coupling.

[0048] It is understandable that, in the embodiment of the present invention, in order to effectively control the rotational speed of the first gear 311 and to change the transmission ratio, the second transmission element 22 may also include at least one transmission gear 222. The transmission gear 222 is connected to the support 10. The transmission gear 222 is located between the second gear 221 and the drive motor 21. The transmission gear 222 is used to transmit the output power from the drive motor 21 to the second gear 221, and the gear shaft of the transmission gear 222 is parallel to the gear shaft of the second gear 221.

[0049] For example, the second transmission element 22 may include a transmission gear 222, the transmission gear 222 being a third gear located in the support 10.The gear shaft of the third gear is connected to the drive shaft of the drive motor 21; the third gear and the second gear 221 are meshed. Alternatively, the second transmission element 22 can comprise two transmission gears 222, the two transmission gears 222 being a third and a fourth gear, the third gear being located in the bracket 10, the gear shaft of the third gear being connected to the drive shaft of the drive motor 21, the fourth gear being located in the bracket 10, and the fourth gear being meshed with the third gear and the second gear 221 respectively.

[0050] In the first conceivable embodiment of the present invention, 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, and there is a first predefined angle 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 predefined angle. This first predefined angle ensures the meshing of the helical gear and the spur gear, and prevents mutual interference between the first ratio 311 and the second ratio 221.

[0051] The first gear 311 can rotate relative to the support 10. For example, a first mounting hole is provided on the support 10, the gear shaft of the first gear 311 enters through the first mounting hole, and the first mounting hole is an inclined hole. The second gear 221 can rotate relative to the support 10; for example, a second mounting hole is provided on the support 10, the gear shaft of the second gear 221 enters through the second mounting hole, and the second mounting hole is a straight hole.

[0052] On this basis, when the second transmission element 22 further comprises a transmission gear 222, the transmission gear 222 is a spur gear and the gear shaft of the transmission gear 222 is parallel to the gear shaft of the second gear 221. The transmission gear 222 is installed in the support 10, and the transmission gear 222 can rotate relative to the support 10, for example, a third mounting hole is provided on the support 10, the gear shaft of the transmission gear 222 enters through the third mounting hole and the third mounting hole is a spur hole.

[0053] In another conceivable embodiment of the present invention, 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 there is a first predefined angle between the gear shaft of the first gear 311 and the gear shaft of the second gear 221. In the second gear 221, the angle between the gear teeth and the gear shaft is also the first predefined angle. This first predefined angle ensures the meshing of the helical gear and the spur gear, and prevents mutual interference between the first ratio 311 and the second ratio 221.

[0054] The first gear 311 can rotate relative to the support 10. For example, a first mounting hole is provided on the support 10, the gear shaft of the first gear 311 enters through the first mounting hole and the first hole of The mounting hole is an inclined hole. The second gear 221 can rotate relative to the support 10, for example, a second mounting hole is disposed on the support 10, the gear shaft of the second gear 221 enters through the second mounting hole and the second mounting hole is a straight hole.

[0055] On this basis, when the second transmission element 22 further comprises a transmission gear 222, the transmission gear 222 is a helical gear and the gear shaft of the transmission gear 222 is parallel to the gear shaft of the second gear 221. The transmission gear 222 is installed in the support 10, and the transmission gear 222 can rotate relative to the support 10. For example, a third mounting hole is provided on the support 10, the gear shaft of the transmission gear 222 enters through the third mounting hole and the third mounting hole is a straight hole.

[0056] It should be noted that in other conceivable embodiments of the present invention, the first gear 311 and the second gear 221 may also be helical gears. The angle between the gear tooth and the drive shaft of the first gear 311 is a first bevel, and the angle between the gear tooth and the gear shaft of the second gear 221 is a second bevel, and the difference between the first bevel angle and the second bevel angle is the first predefined angle. On this basis, the drive gear 222 is a helical gear, and the angle between the gear tooth of the drive gear 222 and the gear shaft is a second conical angle.

[0057] Of course, in practical application, the first transmission element 31 and the second transmission element 22 in the embodiment of the present invention can also be belt drive elements or chain drive elements. For example, the first transmission element 31 comprises a first belt wheel, the second transmission element 22 comprises a second belt wheel, a drive belt is sheathed over the first and second belt wheels, the drive motor 21 produces energy to drive the second belt wheel to rotate, and the second belt wheel transmits power to the first belt wheel via the drive belt. The first drive shaft 301 of the first belt wheel and the output shaft 201 of the second belt wheel are not parallel.

[0058] In the embodiment of the present invention, the first transmission shaft 301 of the first transmission element 31 is the shaft of the rotating shaft of the first transmission element 31. The gear shaft of the first gear 311 is the shaft of the rotating shaft of the first gear 311, and the gear shaft of the first gear 311 can be formed integrally with the gear body. The gear shaft and gear body are either a separate structure, with the gear shaft passing through the shaft of the gear body. The gear shaft of the second gear 221 is the rotating shaft of the second gear 221, and the gear shaft of the second gear 221 can be integrally formed with the gear body, or the gear shaft and gear body are a separate structure, with the gear shaft passing through the shaft of the gear body. The gear shaft of the transmission gear 222 is the rotating shaft of the transmission shaft, and the gear shaft of the transmission gear 222 can be integrally formed with the gear body, or the gear shaft and gear body are separate structures, with the gear shaft passing through the shaft of the gear body.

[0059] The side brush 32 is connected to the gear shaft of the first gear 311, and the gear shaft of the first gear 311 is inclined, so that the side brush 32 is also inclined. The inclined setting of the side brush 32 creates a predefined angle of inclination between the cleaning surface and the floor during cleaning, and this predefined angle of inclination can improve the collection capacity of the side brush 32 for the cleaning object as the side brush 32 sweeps.

[0060] The side brush 32 can comprise a brush body 321 and a plurality of brush branches 322, and the brush body 321 is connected to the first transmission shaft 301; The plurality of brush branches 322 is connected to the brush body 321, and one end of the brush branches 322 extending away from the brush body 321 is located in the same predefined plane, and the predefined plane is perpendicular to the first transmission shaft 301.

[0061] The brush body 321 may be circular or hemispherical, and a plurality of brush branches 322 are distributed along the circumference on the brush body 321. A plurality of brush branches 322 may be distributed uniformly on the brush body 321, or a plurality of brush branches 322 may be distributed non-uniformly on the brush body 321, and the embodiment of the invention does not specifically limit this.

[0062] The brush arm 322 is separate from the brush body 321 and has a flexible brush segment, and the flexible brush segment is used for cleaning. For example, the brush arm 322 may include a connecting section and a flexible brush section; one end of the connecting section is connected to the brush body 321 and the other end of the connecting section is connected to a flexible brush section.

[0063] It should be noted that in the embodiment of the present invention, one end of the plurality of brush branches 322 eloquent from the brush body 321 is located in the same predefined plane, which means that one end of a plurality The brush branch 322, located away from the brush body 321, lies in the same predefined plane in the initial state. It can also be understood that one side of the brush body 321, located away from the first transmission element 31, is perpendicular to the first transmission shaft 301, and that the plane where the end of the brush branch 322, located away from the brush body 321, is parallel to one side of the brush body 321, located away from the first transmission element 31.

[0064] Optionally, the angle between the first drive shaft 301 and the output shaft 201 can be from 6 degrees to 8 degrees, and based on this, the angle between the predefined plane and the floor formed by a plurality of brush arms 322 is also from 6 degrees to 8 degrees. By setting the angle between the first drive shaft 301 and the output shaft 201 to 6 degrees to 8 degrees, the angle between the side brush 32 and the floor is 6 degrees to 8 degrees, which is conducive to the side brush 32 gathering objects during cleaning.

[0065] The support 10 is used to install the drive module 20 and the side brush module 30. The support 10 may comprise a first wall 11 and a second wall 12. The first wall 11 and the second wall 12 face each other, and a retention space is formed between the first wall 11 and the second wall 12. The first transmission element 31 and the second transmission element 22 are arranged in the retention space. The drive motor 21 is arranged on one side of the second wall 12, away from the first wall 11.

[0066] The first transmission element 31 and the second transmission element 22 are connected to the first wall 11, and the output shaft 201 and the first wall 11 are arranged vertically. The drive motor 21 is arranged on one side of the second wall 12 away from the first wall 11, and the drive shaft of the drive motor 21 passes through the second wall 12 and extends into the retention space, and the drive shaft is perpendicular to the second wall 12.

[0067] The first wall 11 is provided with a first mounting hole, and the first mounting hole is an inclined hole, i.e., the axis of the first mounting hole and the first wall 11 are not perpendicular. The first drive shaft 301 of the first transmission element 31 enters through the first mounting hole, and the first drive shaft 301 can rotate within the first mounting hole. The first drive shaft 301 can be inserted directly through the first mounting hole, or a bearing can be disposed in the first mounting hole, and the first drive shaft 301 can be installed in the bearing. When the first transmission part 31 includes a first gear 311, the gear shaft of the first gear 311 is installed in the first mounting hole.

[0068] The first wall 11 is also provided with a second mounting hole, and the second mounting hole is a straight hole, i.e. that the axis of the second The mounting hole is perpendicular to the first wall 11. The output shaft 201 of the second transmission element 22 enters through the second mounting hole and can rotate within it. The output shaft 201 can be directly inserted and positioned in the second mounting hole, or a bearing can be positioned in the second mounting hole, and the output shaft 201 can be installed in the bearing. When the second transmission element 22 includes a second gear 221, the second gear 221 is installed in the second mounting hole.

[0069] In the embodiment of the present invention, the first mounting hole is configured as an inclined hole, the second mounting hole is configured as a straight hole, the first drive shaft 301 of the first transmission element 31 is thus inclined through the first inclined mounting hole, and the side brush 32 is inclined, which facilitates the gathering and collection of cleaning objects. The complexity and production cost are reduced thanks to the second inclined mounting hole (the design complexity and machining cost of the straight hole on the first wall 11 are lower than the design complexity and machining cost of the inclined hole). Furthermore, the second mounting hole is a straight hole, which can reduce the space occupied by the second transmission element 22 in the vertical direction, and is conducive to improving the rationality of the configuration and design of the cleaning robot.

[0070] When the second transmission element 22 further comprises at least one transmission gear 222, at least one third mounting hole may be disposed on the first wall 11, and the third mounting hole is a straight hole, i.e. the third mounting hole is perpendicular to the first wall 11. The gear shaft of the transmission gear 222 enters 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 disposed in the third mounting hole, and the gear shaft of the transmission gear 222 may be installed in the bearing.

[0071] By setting the gear shaft of the second gear 221 and the transmission gear 222 perpendicular to the first wall 11, the gear shaft of the first gear 311 is an inclined shaft, so that there is only one inclined hole on the first wall 11, which not only ensures the inclination of the side brush 32, but also effectively guarantees the convenience of processing the first wall 11 and the utilization rate of cleaning the internal space of the robot.

[0072] The second wall 12 and the first wall 11 are arranged in parallel, forming a retention space between the first wall 11 and the second wall 12. The first wall 11 and the second wall 12 can be connected by a connecting arm. The end of the connecting arm is connected to the first wall 11 and the other end of the connecting arm is connected to the second wall 12, and the connecting arm is located on one side of the support 10, and the other side of the support 10 forms an opening.

[0073] The cleaning brush assembly 100 is mounted on the housing of the cleaning robot, and the housing has a base plate that faces the ground when the cleaning robot is operating. The first wall 11 is parallel to the base plate, or the first side can be recessed into the base plate. That is, the first drive shaft 301 and the base plate of the first transmission element 31 are arranged obliquely, and the drive shaft of the drive motor 21 and the output shaft 201 of the second transmission element 22 and the base plate are arranged vertically.

[0074] In one conceivable embodiment, the first wall 11 is located in the housing, and the first side is parallel to the lower plate, and on this basis, the lower plate is provided with a through hole, the through hole being used to install a side brush 32. The first transmission shaft 301 enters through the through hole which may be an inclined hole (the through hole is not perpendicular to the first wall 11).

[0075] In another conceivable embodiment, the first wall 11 is integrated into the base plate. A retention zone is disposed on the base plate, a retention through-hole is disposed in the retention zone, the first wall 11 is disposed in the retention through-hole, and the first wall 11 is connected to the lower plate. For example, the first wall 11 and the lower plate may be connected by snap-fit ​​or clip-fit, or the first wall 11 and the lower plate may be fixed together by adhesive.

[0076] The first wall 11 and the base plate are arranged parallel, so that the drive shafts of the second gear 221 and the transmission 222 are arranged perpendicular to the base plate. Because the size of the gear in the direction of the gear shaft is small, the second gear 221 and the transmission gear 222 are arranged in such a way that the size occupied by the gear in the vertical direction of the cleaning robot can be reduced and the compactness of the cleaning robot is further improved.

[0077] The embodiment of the present invention relates to a set of cleaning brushes 100, comprising a support 10, a drive module 20 and a side brush module 30. The drive module 20 is located in the support 10. The side brush module 30 comprises a first transmission element 31 and a side brush 32. The first transmission element 31 is located in the support 10. The side brush 32 is connected to the first transmission element 31. The drive module 20 drives the first transmission element 31 to drive The rotation of the side brush 32, and the output shaft 201 of the first transmission element 31 and the drive module 20 are not parallel, Thus, the side brush 32 is inclined during work, and the side brush 32 can gather the cleaning object in one direction, thus improving the ability of the cleaning robot to gather and collect the cleaning object.
