Since the roller brush is usually large in size, the length of the roller brush also has a large tolerance, which makes the entire roller brush too long to fit in or too short to fit in or not concentric when installed. These defects cause wear on the driving part and increase the energy consumption of the product. Summary of the invention

The second ball socket and the second ball head are axially inserted and matched to enable an adjustable relative swinging ability therebetween. The third ball head and the third ball socket are axially inserted and matched to enable an adjustable relative swinging ability therebetween. A plurality of axial grooves are sequentially provided on the outer circumferences of the second ball head and the third ball head.

[0034] As Figures 1 to 17 shown, a photovoltaic robot adopting the transmission structure of the present disclosure includes a bracket 30 and a traveling wheel 31, and the following transmission structure of the rotary brush is installed on the bracket 30. From Figure 1 、 2 、3, the photovoltaic robot is longer to provide a larger coverage area. In this way, the cleaning efficiency of the photovoltaic panel surface is higher. The length of the photovoltaic robot is manufactured according to the maximum width achieved by the laying on the photovoltaic panel surface.

[0035] As Figure 1 、 2 、3, 4, 5, 6 shown, the transmission structure includes a plurality of rotary brush bodies, and the plurality of rotary brush bodies are sequentially connected in transmission along the length direction of the photovoltaic robot to form a rotary brush 1. Both ends of the rotary brush 1 are rotatably connected and supported on the photovoltaic robot. Among them, a first axial socket structure is provided at the first end 4 of the rotary brush body on the output side of the electric motor. The first axial socket structure includes a first ball head 6 and a first ball socket 7 provided between the first end 4 and the output shaft 5 of the electric motor. The first ball head 6 and the first ball socket 7 are axially inserted and matched to enable an adjustable ability of relative swing between the two. A plurality of axial grooves 8 are sequentially provided on the outer circumference of the first ball head 6. Correspondingly, a plurality of axial protrusions 9 are sequentially provided on the inner circumference of the first ball socket 7. When the first ball head 6 and the first ball socket 7 are axially inserted and matched, the axial grooves 8 and the axial protrusions 9 are inserted and matched with each other to achieve circumferential transmission.

[0036] In addition, a second axial sleeve structure is provided between adjacent roller brush bodies. The adjacent roller brush bodies are respectively marked as the first roller brush body 2 and the second roller brush body 3 along the length direction of the photovoltaic robot. The second axial sleeve structure includes a second ball socket 10, a first ball head section 11 and a third ball socket 12. The first ball head section 11 is rotatably supported on the photovoltaic robot. The second ball head 13 and the third ball head 14 are respectively provided at both ends of the first ball head section 11. The second end 15 and the third end 16 adjacent to the first roller brush body 2 and the second roller brush body 3 are respectively provided with the second ball socket 10 and the third ball socket 12. The first roller brush body 2, the second ball head 13, the third ball head 14 and the second roller brush body 3 are respectively provided with the second ball socket 10 and the third ball socket 12. The length direction is arranged in sequence, the second ball socket 10 and the second ball head 13 are axially plug-fitted so that the two have the ability to swing relative to each other, the third ball head 14 and the third ball socket 12 are axially plug-fitted so that the two have the ability to swing relative to each other, the outer circumference of the second ball head 13 and the third ball head 14 are sequentially provided with a plurality of axial grooves 8, and correspondingly, the inner circumference of the second ball socket 10 and the third ball socket 12 are sequentially provided with a plurality of axial protrusions 9, when the second ball head 13 and the second ball socket 10 are axially plug-fitted and when the third ball head 14 and the third ball socket 12 are axially plug-fitted, the axial grooves 8 and the axial protrusions 9 are plug-fitted with each other to realize circumferential transmission.

[0037] In this example, electric motors are provided at both ends of the roller brush 1, and both are transmission-connected to the two ends of the roller brush 1 through the first axial sleeve structure, and two roller brush bodies are provided, and the roller brush 1 is composed of two roller brush bodies. The two first axial sleeve structures can be different, for example Figure 4 The figure shows a mounting seat 19 and a second ball head section 23. Figure 6 The figure shows that there is no mounting seat 19 and the second ball head section 23 , but a connecting shaft 17 is provided, the first ball head 6 is directly provided on the connecting shaft 17 , and a countersunk hole 26 is provided in the first ball head 6 .

[0038] In some embodiments, Figure 4 , 10, as shown in FIGS. 11, a connecting shaft 17 is further provided on one side of the output shaft 5 of the electric motor. One end of the connecting shaft 17 is connected to the output shaft 5, and a fourth ball socket 18 is provided at the other end of the connecting shaft 17. An installation seat 19 is further included. The installation seat 19 is provided with an axially through hole 20. One end of the axially through hole 20 is rotatably sleeved with the connecting shaft 17. A bearing installation portion 21 is provided at the other end of the axially through hole 20. A first bearing 22 is installed in the bearing installation portion 21. The first axially sleeved structure is further provided with a second ball head section 23. The second ball head section 23 is respectively provided with a fourth ball head 24 and a first ball head 6 at both ends. The second ball head section 23 is sleeved with the first bearing 22 and is rotationally supported by the first bearing 22. The second ball head section 23 is rotatably sleeved with the axially through hole 20. And the fourth ball head 24 is axially inserted and matched with the fourth ball socket 18 so that there is an adjustable ability of relative swing between the two. A plurality of axial grooves 8 are sequentially arranged on the outer circumferential direction of the fourth ball head 24. Correspondingly, a plurality of axial protrusions 9 are sequentially arranged on the inner circumferential direction of the fourth ball socket 18. When the fourth ball head 24 is axially inserted and matched with the fourth ball socket 18, the axial grooves 8 and the axial protrusions 9 are inserted and matched with each other to realize circumferential transmission. In this way, the output shaft 5 of the electric motor is not affected by eccentricity, and the wear and loss of the electric motor are reduced.

[0039] Further, as shown in FIGS. Figure 6 , 12 13, the connecting shaft 17 is provided with a shaft insertion hole 25. A counterbore 26 is provided at the bottom of the fourth ball socket 18. The counterbore 26 is communicated with the shaft insertion hole 25. The shaft insertion hole 25 is used for being inserted and connected with the output shaft 5 for circumferential transmission. A bolt 27 is inserted through the counterbore 26 and bolt-connected with the output shaft 5. This bolt connection makes the output shaft 5 and the connecting shaft 17 relatively connected and fixed. In this way, the structure is compact and the axial dimension is short.

[0040] Further, as shown in FIGS. Figure 15 , 16 14, the diameter of the fourth ball head 24 is smaller than the diameter of the first ball head 6. This is beneficial to reducing the diameter of the installation seat 19, so that while other structures such as electric motors need to be installed at both ends of the photovoltaic robot, the installation seat 19 can still be accommodated.

[0041] In some embodiments, as shown in FIGS. Figure 1 , 2As shown in , 5, the first ball head section 11 is rotatably supported on the photovoltaic robot, which means that: it also includes a second bearing 28 and a removable cover plate 29, the second bearing 28 is sleeved on the first ball head section 11, and the removable cover plate 29 is used to fix the second bearing 28 on the photovoltaic robot from bottom to top, for example, the removable cover plate 29 is fixed on the photovoltaic robot from bottom to top by bolts, so that a bearing seat is formed between the removable cover plate 29 and the inner top surface of the photovoltaic robot, and the bearing seat is installed and fixed with the second bearing 28. In this way, the first ball head section 11 is better supported for rotation, and it is also convenient for disassembly and assembly, that is, by removing the removable cover plate 29, the first ball head section 11 can be easily removed from top to bottom, and in this example, the middle part of the roller brush 1 is removed downward, so that the two ends of the roller brush 1 can be separated from the corresponding first ball head 6, so that the entire roller brush 1 can be easily removed for replacement or maintenance. It is conceivable that if there are three or more roller brush bodies, the disassembly and assembly can also be performed with reference to the structure of the aforementioned two roller brush bodies, that is, the same disassembly and assembly can be performed through the detachable cover plate 29.

[0042] In some embodiments, Figure 7 , 8 As shown in FIGS. 9 and 16, the first ball head 6, the second ball head 13 and the third ball head 14 are all configured as bullet-shaped protrusions with spherical front ends, and the first ball socket 7, the second ball socket 10 and the third ball socket 12 are configured as bullet-shaped depressions with spherical bottoms. This has better self-adjustment performance.

[0043] Similarly, if Figure 15 As shown, the fourth ball head 24 may also be a bullet-shaped protrusion, such as Figure 12 As shown, the fourth ball socket 18 may also be a bullet-shaped depression.

[0044] In order to have better self-adjustment performance, the first ball head 6, the second ball head 13, the third ball head 14 and the fourth ball head 24 are all made of plastic material. Similarly, the first ball socket 7, the second ball socket 10, the third ball socket 12 and the fourth ball socket 18 are also made of plastic material. In this way, the elasticity of the plastic material is utilized to obtain better self-adjustment performance.

[0045] When understanding the present disclosure, if necessary, the above structure can refer to other embodiments / appendices. Figure 1 And understand, no further elaboration here.

[0046] The above description is only an illustrative embodiment of the present invention, so any equivalent changes or modifications made according to the structure, characteristics and principles described in the patent protection scope of the present invention are included in the patent protection scope of the present invention.
