[0042] The exemplary embodiment of the present invention first relates to a cleaning brush assembly 100. As shown in [Fig.l] and [Fig.2], the cleaning brush assembly 100 comprises a holder 10, a drive module 20 and a side brush module 30, the drive module 20 is located in the holder 10 and the drive module 20 has an output shaft 201; The side brush module 30 comprises a first transmission part 31 and a side brush 32.

The first transmission member 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 holder 10, a drive module 20 and a side brush module 30. The drive module 20 is located in the holder 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 holder 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 member 31 and the output shaft 201 of the drive module 20 are not parallel. Thus, the side brush 32 is inclined when working, and the side brush 32 can gather the cleaning objects in one direction, thereby improving the ability of the cleaning robot to gather and collect the 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 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 is fitted to the drive module 20, the first transmission member 31 is driven to rotate through the drive module 20, and the side brush 32 is driven to rotate when the first transmission member 31 rotates. The first transmission member 31 has a first transmission shaft 301; the first transmission shaft 301 penetrates through the bracket 10, and the first transmission member 31 rotates along the first transmission shaft 301 under the drive of the drive module 20.

[0046] The drive module 20 comprises a drive motor 21 and a second transmission member 22, and the drive motor 21 has a drive shaft; the second transmission member 22 is connected to the drive motor 21, the drive motor 21 can drive the second transmission member 22 to rotate, the output shaft 201 is located on the second transmission member 22, the second transmission member 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 comprises 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 penetrates 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 in the holder 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 change the transmission ratio, the second transmission member 22 may also include at least one transmission gear 222, the transmission gear 222 is connected to the carrier 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 of the drive motor 21 to the second gear 221, and the gear shaft of the transmission gear 222 is parallel to the gear shaft to the second gear 221.

[0049] For example, the second transmission member 22 may include a transmission gear 222, the transmission gear 222 being a third gear that is located in the carrier 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 may comprise two transmission gears 222, the two transmission gears 222 may be a third and a fourth gear, the third gear being located in the carrier 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 carrier 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 avoids mutual interference between the first gear 311 and the second gear 221.

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

[0052] On this basis, when the second transmission member 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 bracket 10, and the transmission gear 222 can rotate relative to the bracket 10, for example, a third mounting hole is provided on the bracket 10, the gear shaft of the transmission gear 222 penetrates through the third mounting hole, and the third mounting hole is a straight 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 avoids mutual interference between the first gear 311 and the second gear 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 penetrates through the first mounting hole, and the first mounting hole mounting is an inclined hole. The second gear 221 can rotate relative to the bracket 10, for example, a second mounting hole is provided on the bracket 10, the gear shaft of the second gear 221 penetrates through the second mounting hole, and the second mounting hole is a straight hole.

[0055] On this basis, when the second transmission member 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 bracket 10, and the transmission gear 222 can rotate relative to the bracket 10. For example, a third mounting hole is provided on the bracket 10, the gear shaft of the transmission gear 222 penetrates 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 transmission 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 transmission gear 222 is a helical gear, and the angle between the gear tooth of the transmission gear 222 and the gear shaft is a second bevel 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 may also be belt transmission elements or chain transmission elements. For example, the first transmission element 31 comprises a first belt wheel, the second transmission element 22 comprises a second belt wheel, a transmission belt is sheathed on the first belt wheel and the second belt wheel, the drive motor 21 generates power to drive the second belt wheel to rotate, and the second belt wheel transmits the power to the first belt wheel via the transmission belt. The first transmission 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 member 31 is the shaft of the rotating shaft of the first transmission member 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 may be integrally formed with the gear body, or the gear shaft and the gear body are a split structure, and the gear shaft penetrates through the shaft of the gear body. The gear shaft of the second gear 221 is the shaft of the rotating shaft of the second gear 221, and the gear shaft of the second gear 221 may be integrally formed with the gear body, or the gear shaft and the gear body are a split structure, and the gear shaft penetrates through the shaft of the gear body. The gear shaft of the transmission gear 222 is the shaft of the rotating shaft through the transmission shaft, and the gear shaft of the transmission gear 222 may be integrally formed with the gear body, or the gear shaft and the gear body are split structures, and the gear shaft penetrates 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 side brush 32 of the inclined adjustment forms a preset inclination angle between the cleaning and the floor during cleaning, and the preset inclination angle can improve the collection capacity of the side brush 32 for the cleaning object when the side brush 32 sweeps.

[0060] The side brush 32 may 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 uniformly distributed on the brush body 321, or a plurality of brush branches 322 may be non-uniformly distributed on the brush body 321, and the embodiment of the invention does not specifically limit this.

[0062] The brush branch 322 is separated from the brush body 321 and has a flexible brush segment, and the flexible brush segment is used for cleaning. For example, the brush branch 322 may comprise 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 away from the brush body 321 is located in the same predefined plane, which means that one end of a plurality of brush branches 322 remote from the brush body 321 is located in the same predefined plane in the initial state. It can also be understood that one side of the brush body 321 remote 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 remote from the brush body 321 is located is parallel to one side of the brush body 321 remote from the first transmission element 31.

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

[0065] The bracket 10 is used for installing the drive module 20 and the side brush module 30, the bracket 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 retaining space is formed between the first wall 11 and the second wall 12, and the first transmission member 31 and the second transmission member 22 are arranged in the retaining space. The drive motor 21 is arranged on a 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, that is, the axis of the first mounting hole and the first wall 11 are not perpendicular. The first transmission shaft 301 of the first transmission member 31 penetrates through the first mounting hole, and the first transmission shaft 301 can rotate in the first mounting hole. The first transmission shaft 301 can be directly inserted through the first mounting hole, or a bearing can be disposed in the first mounting hole, and the first transmission shaft 301 be installed in the bearing. When the first transmission part 31 comprises 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., the axis of the second mounting hole is perpendicular to the first wall 11. The output shaft 201 of the second transmission member 22 penetrates through the second mounting hole and the output shaft 201 can rotate in the second mounting hole. The output shaft 201 can be directly inserted and disposed in the second mounting hole, or a bearing can be disposed in the second mounting hole, and the output shaft 201 be installed in the bearing. When the second transmission part 22 comprises 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 transmission shaft 301 of the first transmission part 31 is thus inclined through the first inclined mounting hole, and the side brush 32 is inclined, which is conducive to the gathering and collection of cleaning objects. The complexity and production cost are reduced by virtue of the second inclined mounting hole (the design complexity and processing cost of the straight hole on the first wall 11 are lower than the design difficulty and processing cost of the 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, 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 provided 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 penetrates 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 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 may be connected by a connecting arm. A one 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 working. The first wall 11 is parallel to the base plate, or the first side may be embedded in the base plate. That is, the first transmission shaft 301 and the base plate of the first transmission part 31 are arranged obliquely, and the drive shaft of the drive motor 21 and the output shaft 201 of the second transmission member 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 bottom plate, and on this basis, the bottom plate is provided with a through hole, the through hole being used to install a side brush 32. The first transmission shaft 301 penetrates 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 area is provided on the base plate, a retention through-hole is provided in the storage area, the first wall 11 is provided in the retention through-hole, and the first wall 11 is connected to the bottom plate. For example, the first wall 11 and the bottom plate may be connected by snap-fastening or clipping, or the first wall 11 and the bottom plate may be fixed together by glue.

[0076] The first wall 11 and the base plate are arranged in parallel, so that the transmission 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 gear shaft direction is small, the second gear 221 and the transmission gear 222 are arranged such that the size occupied by the gear in the height 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 cleaning brush assembly 100, comprising a holder 10, a drive module 20 and a side brush module 30, the drive module 20 is located in the holder 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 holder 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 when working, and the side brush 32 can gather the cleaning object in one direction, thereby improving the ability of the cleaning robot to gather and collect the cleaning object.
