[0038] like Figure 1 , Figure 2 as well as Figure 3As shown, this embodiment provides a cleaning robot, which generally works on a photovoltaic panel, has good grip, and can travel on an inclined plane. The cleaning robot includes a body 1, which includes a substrate 14, two oppositely arranged baffles 15, two oppositely arranged upper connecting rods 11, and two oppositely arranged lower connecting rods. The substrate 14 is in a long strip shape, and the substrate 14 includes two long sides. The two oppositely arranged baffles 15 are respectively connected to the two ends of the substrate 14, and are perpendicular to the substrate 14, and the two baffles 15 extend downward in the vertical direction. The two ends of each upper connecting rod 11 are respectively connected to the two baffles 15, and the two upper connecting rods 11 are abutted against the lower surface of the substrate 14, and are respectively arranged opposite to the two long sides of the substrate 14. The two ends of each lower connecting rod are respectively connected to the two baffles 15, and the two lower connecting rods are respectively located directly below the two upper connecting rods 11. The cleaning robot also includes two fixing frames 16, which are rectangular, and one vertex of each fixing frame 16 is fixedly connected to an upper connecting rod 11 or a lower connecting rod. The fixing frame 16 is used to fix a pair of upper connecting rods 11 and a pair of lower connecting rods to enhance the stability and rigidity of the vehicle body 1 .

[0039] The cleaning robot also includes a traveling device 3 and a pair of cleaning devices 4, each of which is arranged at the bottom of the vehicle body 1, and the traveling device 3 enables the cleaning robot to move forward on the inclined photovoltaic panel. A pair of cleaning devices 4 are respectively arranged on the two sides of the vehicle body 1 that are away from each other, and each cleaning device 4 is connected to the vehicle body 1 through two lifting devices 5. The cleaning device 4 can automatically complete the cleaning operation on the solar panel 6, and the lifting device 5 can control the cleaning device 4 to rise or fall relative to the vehicle body 1. The cleaning robot also includes a controller 2, which is located between the two upper connecting rods 11 and between the two lower connecting rods, and is fixedly connected to the two upper connecting rods 11 and the two lower connecting rods. The controller 2 is used to control the travel of the cleaning robot, the operation of the cleaning device 4, and the operation of the lifting device 5. The controller 2 includes a control box and a circuit board. The substrate 14 is provided with a through hole, and the top of the control box protrudes from the through hole. The top of the control box is provided with a box cover that can be opened, and the circuit board is arranged inside the control box, and the circuit board is used to realize the circuit connection of the controller 2. The cleaning robot also includes a solar panel 6 and a battery pack. The photovoltaic panel is arranged on the top surface of the substrate 14, and the battery pack is arranged inside the control box and is electrically connected to the solar panel 6. When the cleaning robot is working or on standby, the solar panel 6 can charge the battery pack to maintain the power consumption of the cleaning robot itself when it is working.

[0040] like Figure 1 , Figure 3 as well as Figure 4As shown, the lifting device 5 includes a first arm 51, a second arm 52, a telescopic rod 53 and a connecting plate 54. The first end of the first arm 51 is fixedly connected to the first lower connecting rod 12, and the second end thereof extends in the direction of the second lower connecting rod 13. The first end of the second arm 52 is fixedly connected to the second lower connecting rod 13, and the second end thereof extends in the direction away from the first lower connecting rod 12. The first end of the telescopic rod 53 is rotatably connected to the second end of the first arm 51, and the second end of the telescopic rod 53 extends toward the cleaning device 4. The telescopic rod 53 is electrically connected to the controller 2, so that the controller 2 can control the telescopic rod 53 to rotate with the second end of the first arm 51 as the center. The first end of the connecting plate 54 is rotatably connected to the second end of the second arm 52, the second end of the connecting plate 54 is rotatably connected to the second end of the telescopic rod 53, and the connecting plate 54 is fixedly connected to the cleaning device 4. When the telescopic rod 53 rotates and turns counterclockwise, the second end of the connecting plate 54 moves with the second end of the telescopic rod 53 and rotates clockwise with the second end of the telescopic rod 53 as the center. Since the first end of the connecting plate 54 is rotatably connected to the second end of the second arm frame 52 at this time, the second end of the connecting plate 54 rotates counterclockwise with the second end of the second arm frame 52 as the center, and the counterclockwise rotation of the connecting plate 54 drives the cleaning device 4 to rotate counterclockwise, so that the cleaning device 4 is lifted. When the telescopic rod 53 rotates and turns clockwise, the second end of the connecting plate 54 moves with the second end of the telescopic rod 53 and rotates counterclockwise with the second end of the telescopic rod 53 as the center. Since the first end of the connecting plate 54 is rotatably connected to the second end of the second arm frame 52 at this time, the second end of the connecting plate 54 rotates clockwise with the second end of the second arm frame 52 as the center, and the clockwise rotation of the connecting plate 54 drives the cleaning device 4 to rotate clockwise, so that the cleaning device 4 is pressed down.

[0041] like Figure 1 , Figure 3 , Figure 5 as well as Figure 6As shown, the cleaning device 4 includes a roller brush frame 41, a roller brush 42 and a roller brush motor 43. The roller brush frame 41 is fixedly connected to at least one connecting plate 54, and the two ends of the roller brush 42 are rotatably connected to the roller brush frame 41. The roller brush motor 43 is installed to the roller brush frame 41, and the roller brush motor 43 is electrically connected to the controller 2. Among them, the roller brush 42 includes a roller brush 42 rotating shaft, and the roller brush motor 43 includes a second power output shaft, which is connected to the roller brush 42 rotating shaft through a transmission device. The roller brush motor 43 is electrically connected to the controller 2, so that the controller 2 can control the roller brush motor 43 to start or shut down the roller brush 42. The cleaning device 4 also includes a pair of brush bodies 44, which are respectively sleeved on the outer surface of the rotating shaft of the roller brush 42 and are located at the two ends of the roller brush 42. Compared with the roller brush 42, the brush body 44 uses harder bristles for cleaning the frame of the photovoltaic panel. The cleaning device 4 also includes three connecting arms 45, and the two ends of each connecting arm 45 are respectively connected to the two long sides of the roller brush frame 41. The connecting arms 45 can strengthen the rigidity of the roller brush frame 41 and prevent the roller brush frame 41 from shaking due to its excessive length. The connecting arms 45 can enhance the stability of the roller brush frame 41, thereby increasing the overall stability of the cleaning device 4.

[0042] The controller 2 can control the lifting device 5 to lift the roller brush 42 of the cleaning robot, so that the roller brush 42 of the cleaning robot is away from the surface of the photovoltaic panel. When the cleaning robot crosses the gap between two adjacent photovoltaic panels, the roller brush 42 will no longer contact the frame of the photovoltaic panel after being lifted. Thereby, the roller brush 42 of the cleaning robot will no longer interfere with the body of the cleaning robot, so that the cleaning robot can cross the gap between two adjacent photovoltaic panels. When the cleaning robot works on the surface of the photovoltaic panel, the controller 2 can also control the lifting device 5 to press down the roller brush 42 of the cleaning robot, so that the bristles of the roller brush 42 can fully contact the photovoltaic panel, and increase the pressure between the roller brush 42 of the cleaning robot and the photovoltaic panel, so that the roller brush 42 of the cleaning robot can more easily remove dust on the photovoltaic panel when rolling, thereby improving the working efficiency of the cleaning robot and improving the user experience.

[0043] like Figure 1 , Figure 3 , Figure 7 , Figure 8 , Fig. 9 as well as Fig.10As shown, the cleaning robot also includes a traveling device 3, which is arranged at the bottom of the vehicle body 1. The traveling device 3 includes a first wheel 31, a wheel motor 32, a first gear 33, a second gear 34 and a transmission belt 35. The first wheel 31 is rotatably mounted to a first side of a baffle 15. The first wheel 31 includes a wheel axle that passes through the baffle 15 and extends to the second side of the baffle 15, and the extension direction of the wheel axle of the first wheel 31 is the same as the extension direction of the substrate 14. The wheel motor 32 is mounted to the first side of the baffle 15, and the wheel motor 32 includes a first power output shaft that passes through the baffle 15 and extends to the second side of the baffle 15. The first gear 33 is arranged on the second side of the baffle 15 and fixed to the wheel axle. The second gear 34 is arranged on the second side of the baffle 15 and fixed to the first power output shaft. The transmission belt 35 is sleeved on the circumferential surface of the first gear 33 and the second gear 34. The inner wall of the transmission belt 35 is provided with a toothed ring, which meshes with the first gear 33 and the second gear 34. The wheel motor 32 is electrically connected to the controller 2, so that the controller 2 can control the wheel motor 32, thereby indirectly controlling the rotation of the transmission belt 35, thereby indirectly controlling the rotation of the first wheel 31. At the same time, the outer surface of the first wheel 31 is tangent to the outer surface of the photovoltaic panel, so that when the first wheel 31 is driven to rotate, the cleaning robot can move on the surface of the photovoltaic panel.

[0044] The traveling device 3 includes a first wheel bracket 36 and a second wheel 37. Both ends of the first wheel bracket 36 are connected to two lower connecting rods. The second wheel 37 is rotatably mounted to the first wheel bracket 36. The traveling direction of the second wheel 37 is perpendicular to the extension direction of the substrate 14. The extension direction of the wheel axle of the second wheel 37 is perpendicular to the extension direction of the substrate 14. When the cleaning robot is working, the outer surface of each second wheel 37 is tangent to the frame of the photovoltaic panel. The second wheel 37 is a driven wheel. When the second wheel 37 is driven by the vehicle body 1, the second wheel 37 can move along the frame of the photovoltaic panel, fix the traveling route of the cleaning robot, and prevent the cleaning robot from slipping off the photovoltaic panel.

[0045] The traveling device 3 includes a second wheel bracket 38 and a third wheel 39. Both ends of the second wheel bracket 38 are connected to two lower connecting rods, and the third wheel 39 is rotatably mounted to the second wheel bracket 38. The extension direction of the wheel axle of the third wheel 39 is the same as the extension direction of the substrate 14. The third wheel 39 is a driven wheel. When the third wheel 39 is driven by the vehicle body 1, the third wheel 39 can move along the surface of the photovoltaic panel.

[0046] like Figures 1 to 10As shown, when the cleaning robot crosses the gap between two adjacent photovoltaic panels, the controller 2 can send a command to the telescopic rod 53 to rotate it counterclockwise, so that the telescopic rod 53 rotates counterclockwise, and the second end of the connecting plate 54 moves along with the second end of the telescopic rod 53, and rotates clockwise with the second end of the telescopic rod 53 as the center. Since the first end of the connecting plate 54 is rotatably connected to the second end of the second arm 52 at this time, the second end of the connecting plate 54 rotates counterclockwise with the second end of the second arm 52 as the center, and the counterclockwise rotation of the connecting plate 54 drives the cleaning device 4 to rotate counterclockwise, so that the cleaning device 4 is lifted, so that the roller brush 42 of the cleaning robot is away from the surface of the photovoltaic panel, and the roller brush 42 will no longer contact the frame of the photovoltaic panel after being lifted. As a result, the roller brush 42 of the cleaning robot will no longer interfere with the body of the cleaning robot, so that the cleaning robot can cross the gap between two adjacent photovoltaic panels.

[0047] When the cleaning robot is working on the surface of the photovoltaic panel, the controller 2 can send a command to the telescopic rod 53 to rotate it clockwise, so that the telescopic rod 53 rotates in the clockwise direction, and the second end of the connecting plate 54 moves along with the second end of the telescopic rod 53, and rotates counterclockwise with the second end of the telescopic rod 53 as the center. Since the first end of the connecting plate 54 is rotatably connected to the second end of the second arm 52 at this time, the second end of the connecting plate 54 rotates clockwise with the second end of the second arm 52 as the center, and the clockwise rotation of the connecting plate 54 drives the cleaning device 4 to rotate clockwise, so that the cleaning device 4 is pressed down, so that the bristles of the roller brush 42 can fully contact the photovoltaic panel, and increase the pressure between the roller brush 42 of the cleaning robot and the photovoltaic panel, so that the roller brush 42 of the cleaning robot can more easily remove dust on the photovoltaic panel when rolling, thereby improving the working efficiency of the cleaning robot and improving the user experience.

[0048] The advantage of this embodiment is that it provides a cleaning robot, which includes a traveling device and a cleaning device, and the cleaning device is connected to the vehicle body through a lifting device. The controller can control the lifting device to lift the roller brush of the cleaning robot, so that the roller brush of the cleaning robot is away from the surface of the photovoltaic panel. When the cleaning robot crosses the gap between two adjacent photovoltaic panels, the roller brush will no longer contact the frame of the photovoltaic panel after being lifted. Therefore, the roller brush of the cleaning robot will no longer interfere with the body of the cleaning robot, so that the cleaning robot can cross the gap between two adjacent photovoltaic panels.

[0049] When the cleaning robot is working on the surface of the photovoltaic panel, the controller can also control the lifting device to press down the roller brush of the cleaning robot so that the bristles of the roller brush can fully contact the photovoltaic panel and increase the pressure between the roller brush of the cleaning robot and the photovoltaic panel, so that the roller brush of the cleaning robot can more easily remove dust on the photovoltaic panel when rolling, thereby improving the working efficiency of the cleaning robot and enhancing the user experience.
