[0038] The core of this application is to provide a cleaning device for cleaning the roller brush of a cleaning robot.

[0039] Another core aspect of this application is to provide a cleaning robot with the aforementioned cleaning device.

[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0041] In related fields, especially in the cleaning of photovoltaic modules, the roller brushes of cleaning robots often experience problems such as bristling, dust accumulation, and dirt sticking to the brush bristles after long-term use. This not only affects the cleaning efficiency of the robot but also shortens the lifespan of the roller brushes.

[0042] Therefore, such as Figure 1 As shown in the figure, this application discloses a cleaning device, including a roller brush assembly 10 and a cleaning assembly 20. By the reciprocating motion of the comb 21 of the cleaning assembly 20 along the axial direction of the rotating shaft 11, the cleaning effect of the roller brush 12 of the cleaning robot can be achieved, ensuring the cleaning efficiency of the cleaning robot and improving the service life of the roller brush 12.

[0043] The following will combine Figures 1 to 12 The cleaning device disclosed in the embodiments of this application will be explained and described in detail.

[0044] Among them, such as Figure 1As shown, the roller brush assembly 10 may include a rotating shaft 11 and a roller brush 12 disposed on the rotating shaft 11. The rotating shaft 11 can drive the roller brush 12 to rotate, thereby achieving the effect of cleaning target objects such as photovoltaic modules. Meanwhile, the cleaning assembly 20 may include a comb 21, which is inserted into the roller brush 12 and can reciprocate along the axial direction of the rotating shaft 11, allowing the comb 21 to clean the entire length of the roller brush 12. Furthermore, when the roller brush 12 rotates, the comb 21 contacts the roller brush 12, and through the reciprocating motion of the comb 21 along the axial direction of the rotating shaft 11, it achieves thorough cleaning of firmly attached dust inside the roller brush 12, improving the cleaning effect of the roller brush 12. It should be noted that a drive motor may be provided at one end of the rotating shaft 11, thereby driving the rotating shaft 11 to rotate.

[0045] In some embodiments, such as Figure 1 As shown, the cleaning assembly 20 may include a moving guide rail 22, a moving base 23, and a drive component 222. Wherein, as... Figure 8 and Figure 9 As shown, the movable guide rail 22 is parallel to the rotation axis 11 and fixed on the robot frame 101 of the cleaning robot 100, and the movable seat 23 is disposed on the movable guide rail 22. At the same time, the combing component 21 is disposed on the movable seat 23, so that the driving component 222 can drive the movable seat 23 to move axially along the rotation axis 11, thereby driving the combing component 21 to move axially along the rotation axis 11 to clean the entire section of the roller brush 12.

[0046] In some embodiments, such as Figure 1 , Figure 8 and Figure 9 As shown, the movable guide rail 22 may include a lead screw 221, and the movable seat 23 may be threadedly engaged with the lead screw 221. A drive member 222 may be disposed at one end of the lead screw 221, so that the lead screw 221 is rotated via the drive member 222, thereby causing the movable seat 23 to move along the lead screw 221. The drive member 222 may be a worm gear mechanism or a lead screw motor, etc., which are not limited herein.

[0047] In some embodiments, such as Figure 10 As shown, the drive component 222 may include a synchronous pulley 2221 fixed to the end of the lead screw 221 and a transmission gear 111 disposed on the outer wall of the rotating shaft 11. The synchronous pulley 2221 and the transmission gear 111 are driven by a synchronous belt 2222, so that the power of the rotating shaft 11 can be transmitted to the lead screw 221 through the synchronous belt 2222. Thus, a drive motor can be used to drive the lead screw 221 and the rotating shaft 11 to rotate, thereby driving the moving seat 23 to move along the lead screw 221, achieving the effect of cleaning the entire section of the roller brush 12. No additional drive component 222 such as a motor is required, which can save costs.

[0048] In some embodiments, such as Figure 11 As shown, the drive unit 222 may also include a tensioning pulley 2223 capable of tensioning the synchronous belt 2222. The tensioning pulley 2223 can be fixed to the robot frame 101, and the tensioning pulley 2223 presses against the outer side of the synchronous belt 2222, so that the synchronous belt 2222 can be tensioned and prevented from loosening through the tensioning pulley 2223.

[0049] In the above embodiments, the moving guide rail 22 can be, but is not limited to, a closed linear module to cope with harsh on-site environments, or a semi-closed linear module equipped with a dust cover. The linear module can be, but is not limited to, a ball screw type, a synchronous belt type, or a linear motor type. Alternatively, the drive component 222 can be a telescopic cylinder, with the telescopic rod connected to the moving seat 23. This allows the moving seat 23 to slide on the moving guide rail 22 via the telescopic rod's extension and retraction, thereby enabling the comb component 21 to move axially along the rotating shaft 11 to clean the entire section of the roller brush 12. This is not a limitation herein.

[0050] The cleaning device disclosed in this application cleans targets such as photovoltaic modules by rotating the rotating shaft 11 of the roller brush assembly 10, thereby driving the roller brush 12 on the rotating shaft 11 to rotate. At the same time, the combing member 21 of the cleaning assembly 20 can be located inside the roller brush 12, and the combing member 21 reciprocates along the axial direction of the rotating shaft 11 to clean the roller brush 12.

[0051] The cleaning device disclosed in this application embodiment can achieve a cleaning effect on the roller brush 12 of the cleaning robot 100 by the reciprocating motion of the comb 21 of the cleaning component 20 along the axial direction of the rotating shaft 11, thereby ensuring the cleaning efficiency of the cleaning robot 100 and improving the service life of the roller brush 12.

[0052] In some embodiments, such as Figure 1 As shown, the cleaning component 20 may also include a mounting plate 24. (As indicated...) Figure 3 and Figure 4 As shown, the mounting plate 24 may have at least one first connecting portion 241 and a second connecting portion 242, that is, the first connecting portion 241 may be one or more, and the second connecting portion 242 may be one or more. Wherein, as Figures 3 to 5As shown, the first connecting part 241 may have multiple connecting holes 2411, so that it can be detachably connected to the movable seat 23 by fasteners such as bolts. Furthermore, the combing component 21 can be adapted to the second connecting part 242, that is, each second connecting part 242 corresponds to one combing component 21. The combing component 21 can be connected to the second connecting part 242, and the combing component 21 can be arranged parallel to the rotation axis 11 of the roller brush 12 to ensure that the roller brush 12 is not damaged while cleaning it, thus improving the service life of the roller brush 12. Of course, the combing component 21 can also be arranged perpendicular to the rotation axis 11 of the roller brush 12, so that the combing component 21 can achieve a better cleaning effect on the roller brush 12 when it reciprocates along the rotation axis 11.

[0053] In some embodiments, such as Figure 5 As shown, the first connecting part 241 and the second connecting part 242 can each be two symmetrically arranged, and each second connecting part 242 can be connected with a combing part 21, so that multiple rows of combing parts 21 can clean the roller brush 12 and ensure a better cleaning effect of the roller brush 12.

[0054] In some embodiments, such as Figure 4 and Figure 6 As shown, one of the comb component 21 and the second connecting part 242 may be provided with an adjustment waist hole 2111, and the other may be provided with a mounting hole 2421 that mates with the adjustment waist hole 2111. That is, the connecting plate 211 may be provided with multiple adjustment waist holes 2111, and the second connecting part 242 may be provided with a mounting hole 2421 that mates with the adjustment waist hole 2111. Alternatively, the second connecting part 242 may be provided with multiple adjustment waist holes 2111, and the connecting plate 211 may be provided with a mounting hole 2421 that mates with the adjustment waist hole 2111, so as to adjust the distance between the comb component 21 and the roller brush 12, thereby ensuring a better cleaning effect on the roller brush 12.

[0055] In some embodiments, such as Figure 6 As shown, the comb 21 may include a connecting plate 211 that can be connected to the second connecting part 242 and a brush 212 disposed on the connecting plate 211, so as to clean the roller brush 12 by the brush 212 contacting the bristles of the roller brush 12.

[0056] In some embodiments, such as Figure 6 and Figure 7 As shown, the brush 212 may include a brush rod 2121 spaced apart on the connecting plate 211 and a ball head 2122 located at the end of the brush rod 2121, so that the brush rod 2121 and the ball head 2122 can contact the bristles of the roller brush 12 to clean the roller brush 12, and avoid damage to the bristles of the roller brush 12.

[0057] In some embodiments, such as Figures 8 to 10As shown, the cleaning device may also include at least one windproof pin 2431, and the windproof pin 2431 may be connected to the movable base 23, that is, the windproof pin 2431 may be directly connected to the movable base 23, or the windproof pin 2431 may be indirectly connected to the movable base 23 through the mounting plate 24. At the same time, a windproof plate 31 is provided on at least one side of the stop position 30, and a socket 311 is provided on the windproof plate 31 for the windproof pin 2431 to be inserted and matched. When the cleaning robot 100 is in the parking position 30, the windproof pin 2431 can be aligned with the socket 311 on the windproof plate 31 on one side of the parking position 30. It can also move along the moving guide rail 22 via the movable seat 23 towards the socket 311 until the windproof pin 2431 is inserted into the socket 311, thereby realizing the windproof self-locking function. When the cleaning robot 100 restarts the cleaning task, the movable seat 23 first returns to the end of the moving guide rail 22 away from the socket 311 to unlock the cleaning robot 100, and then the cleaning action of photovoltaic modules and other target objects can be realized.

[0058] In some embodiments, such as Figure 3 and Figure 4 As shown, the mounting plate 24 may also have at least one third connecting portion 243, that is, there may be one or more third connecting portions 243, and the windproof pin 2431 is fixed to the third connecting portion 243.

[0059] In some embodiments, two third connecting parts 243 may be arranged opposite each other, and two windproof pins 2431 may be used. The two windproof pins 2431 may be located on the opposite side of the two third connecting parts 243, so that the two windproof pins 2431 can be inserted into the holes 311 on the windproof plates 31 on both sides of the stop position 30, thereby making the mounting plate 24 compatible with the situation where the stop position 30 is on both sides of the cleaning robot 100.

[0060] In some embodiments, such as Figures 3 to 5 As shown, the plane where the third connecting part 243 is located can be perpendicular to the plane where the second connecting part 242 is located, and the plane where the third connecting part 243 is located can intersect with the plane where the first connecting part 241 is located, so that the windproof pin 2431 on the third connecting part 243 can be aligned with the socket 311, thereby allowing it to be better inserted into the socket 311.

[0061] In some embodiments, such as Figures 3 to 5 As shown, the mounting plate 24 can be formed by bending sheet metal parts to form the first connecting part 241, the second connecting part 242 and the third connecting part 243, or it can be formed by welding multiple sheet metal parts. This article does not limit this.
