[0034] Please refer to Figures 1 to 13 As shown, the utility model discloses a cleaning robot, including a main body 1, walking wheels 2 symmetrically arranged at both ends of the main body 1, two sets of walking wheel drive assemblies, roller brushes 4, drive assemblies 5 and guide wheels 6. The two sets of walking wheel drive assemblies are respectively used to drive the walking wheels 2 at both ends of the main body 1 to walk along the photovoltaic module, and the drive assembly 5 is used to drive the roller brush 4 to rotate relative to the main body 1 to clean the photovoltaic module.

[0035] See also Figure 2 The main body 1 includes a frame 11 and a box 12 respectively fixed to both ends of the frame 11, and at least part of the walking wheel drive assembly and at least part of the drive assembly 5 are located in the box 12.

[0036] For details, see Figures 3 to 5 The travel wheel drive assembly includes a drive component 31, a drive gear 32, a driven gear 33, and a conveyor belt 34. The driven gear 33 is sleeved onto the axle of the travel wheel 2. The drive gear 32 is connected to the drive shaft of the drive component 31. The conveyor belt 34 is sleeved between the drive gear 32 and the driven gear 33. During the movement of the cleaning robot, the drive component 31 drives the drive gear 32 to rotate, and the drive gear 32 drives the driven gear 33 to rotate via the conveyor belt 34, thereby rotating the travel wheel 2. Optionally, the drive component 31 is a motor and the conveyor belt 34 is a chain.

[0037] The driving component 31 is connected to the box body 12 and is located outside the box body 12. The driving gear 32, the driven gear 33 and the conveyor belt 34 are all located inside the box body 12. The box body 12 protects the driving gear 32, the driven gear 33 and the conveyor belt 34.

[0038] Two running wheels 2 are provided at both ends of the main body 1. The axles of the two running wheels 2 at the same end are both sleeved with driven gears 33. The two driven gears 33 are connected to the same driving gear 32 through two conveyor belts 34; that is, one driving component 31 drives the two driven gears 33 to rotate through two conveyor belts 34, thereby realizing the synchronous rotation of the two running wheels 2 at the same end.

[0039] In the related art, multiple gear meshing transmissions are usually used. The large number of gears leads to a large number of parts, which increases the possibility of mismatch between parts and easily causes operational failures. In this embodiment, gears and chains are used for transmission, which reduces the number of gears, has fewer parts, a simple structure, and is light in weight.

[0040] Continue to see Figures 3 to 5 Two guide wheels 6 are respectively provided at both ends of the cleaning robot. A first bevel gear 71 is connected to the outer portion of the wheel axle of the guide wheel 6, and a second bevel gear 72 is also connected to the outer portion of the wheel axle of the walking wheel 2. The first bevel gear 71 is engaged with the second bevel gear 72. When the walking wheel 2 rotates, the guide wheel 6 is driven to rotate, making the walking process of the cleaning robot smoother.

[0041] The roller brush 4 is tilted relative to the main body 1, forming a certain angle between the roller brush 4 and the photovoltaic panel. In related art, the roller brush 4 is arranged parallel to the main body 1. When the cleaning robot is in operation, dust is swept in the direction of the robot's movement. In this embodiment, the tilted roller brush 4 facilitates the natural fall of dust along the photovoltaic panel, improving dust removal and cleaning efficiency.

[0042] For details, see Figure 6 The angle formed by the length direction L1 of the roller brush 4 and the length direction L2 of the main body 1 is an acute angle, that is, the roller brush 4 is inclined at a small angle relative to the main body 1, making it easy for the roller brush 4 and the driving assembly 5 to cooperate.

[0043] See also Figure 7 The roller brush 4 includes a roller brush shaft 41 and a roller brush portion 42. The roller brush portion 42 is fixed around the outer periphery of the roller brush shaft 41. The roller brush portion 42 can be a brush of various types, and can perform the function of cleaning the surface of the photovoltaic module. Figure 12 and Figure 13 Both ends of the roller brush shaft 41 are provided with mounting grooves 411, which extend through the inner circumference and outer end surfaces of the roller brush shaft 41. The roller brush shaft 41 also has mounting holes 412, which are symmetrically arranged at the ends of the roller brush shaft 41 and communicate with the mounting grooves 411. Optionally, the mounting holes 412 are waist-shaped holes.

[0044] In this embodiment, see Figure 9 and Figure 10The driving assembly 5 includes a driving member 51, shaft members 52 respectively connected to the two ends of the roller brush 4, a bearing 53 sleeved on the outside of each shaft member 52, and a bearing seat 54. The driving member 51 is connected to one of the two shaft members 52, one of the two shaft members 52 is the driving end, and the other is the driven end. The driving member 51 and the bearing seat 54 are connected to the box body 12, and the bearing seat 54 is connected to the side wall of the box body 12 close to the roller brush 4, and the bearing 53 is installed obliquely on the bearing seat 54.

[0045] In this embodiment, see Figure 9 The drive assembly 5 further includes a driving gear 55, a driven gear 56, and a transmission member 57. The driving gear 55 is connected to the drive shaft of the driving member 51, the driven gear 56 is connected to the shaft 52, and the transmission member 57 is sleeved on the driving gear 55 and the driven gear 56. The driving member 51 drives the driving gear 55 to rotate, and the driving gear 55 drives the driven gear 56 to rotate through the transmission member 57, thereby rotating the roller brush 4. The driving gear 55, the driven gear 56, and the transmission member 57 are all located within the housing 12. In other possible embodiments, the driving member 51 can also directly drive the shaft 52.

[0046] See also Figure 9 The shaft 52 is connected to the roller brush 4 by a bolt. The shaft 52 has a through hole 521. A portion of the shaft 52 is mounted in the mounting groove 411 of the roller brush 4. The bolt passes through the through hole 521 and the mounting hole 412 and is connected to the nut. The mounting hole 412 is set as a waist-shaped hole to facilitate adjustment of the bolt installation position.

[0047] In some embodiments, the shaft 52 can rotate around the bolt toward the opening on the side of the mounting slot 411, that is, the shaft 52 is movably connected to the roller brush 4. In other possible embodiments, the shaft 52 is fixedly connected to the roller brush 4.

[0048] See also Figure 11 The bearing seat 54 is provided with an axial hole 541 for the shaft 52 to pass through and a bearing cavity 542 for installing the bearing 53. The axial hole 541 and the bearing cavity 542 are coaxial and connected to each other. The axis of the bearing cavity 542 is inclined relative to the outer axis of the bearing seat 54, so that the bearing 53 installed in the bearing cavity 542 is inclined relative to the bearing seat 54, and the bearing 53 is matched with the roller brush 4, thereby realizing the relative inclination of the roller brush 4 and the main body of the cleaning robot.

[0049] See also Figure 2 The cleaning robot includes a photovoltaic panel 8, which is fixed to the outside of the frame 11 and is used to supply power to the cleaning robot.

[0050] Continue to see Figure 2The cleaning robot includes a controller 9, which is fixed under the frame 11 and located between the frame 11 and the roller brush 4 in the thickness direction of the cleaning robot. This arrangement makes the weight distribution of the cleaning robot uniform and the center of gravity stable, and the cleaning robot is not easy to deviate when walking.
