[0064] Referring to Figure 5 , Figure 5 A schematic diagram of the split structure of the outer ring 131 of the spherical bearing in the connecting mechanism 10 of an embodiment of the present application is shown. In some embodiments, the outer ring of the spherical bearing includes a first outer ring 1311 and a second outer ring 1312, which are arranged along the radial direction of the outer ring of the spherical bearing. A third mounting assembly 18 is arranged between the first outer ring 1311 and the second outer ring 1312, which fixedly connects the first outer ring 1311 and the second outer ring 1312.

[0065] Referring to Figure 5 and Figure 6 , Figure 6 A schematic diagram of the structure of the inner ring 132 of the spherical bearing in the connecting mechanism 10 of an embodiment of the present application is shown. In some embodiments, the outer ring 131 of the spherical bearing is configured as a ball bearing outer ring, and the inner ring 132 of the spherical bearing is configured as a ball bearing inner ring, which is connected to the assembly seat body 12 in a spherical manner, and the inner ring 132 of the spherical bearing is connected to the outer ring of the spherical bearing in a spherical manner.

[0066] Specifically, the inner part of the outer ring 131 of the spherical bearing is spherical, and the outer part of the inner ring 132 of the spherical bearing is spherical, which can be installed in the spherical space of the outer ring 131 of the spherical bearing, so that the inner ring 132 of the spherical bearing can only rotate in the inner surface of the outer ring 131 of the spherical bearing, so that the first connecting body 141 and the second connecting body 412 can drive the first to-be-connected part 20 and the second to-be-connected part 30 to rotate freely, respectively, to adapt to complex terrain. The outer ring 131 of the spherical bearing is installed inside the assembly seat body 12 and outside the inner ring 132 of the spherical bearing, which splits the outer ring 131 of the spherical bearing into two parts, which can facilitate the installation of the spherical bearing. The first outer ring 1311 and the second outer ring 1312 are arranged in a split manner along the radial direction of the outer ring 131 of the spherical bearing, and the first seat body 121 and the second seat body 122 are arranged in a split manner along the axial direction of the assembly seat body 12, so that the split directions of the outer ring 131 of the spherical bearing and the assembly seat body 12 are staggered, further improving the structural strength and stability of the outer ring 131 of the spherical bearing and the assembly seat body 12.

[0067] Referring to Figure 5In some embodiments, the third mounting assembly 18 comprises a positioning pin 181 and a positioning hole 182 into which the positioning pin 181 is inserted.

[0068] Specifically, in some embodiments, the positioning pin 181 is arranged on the first outer ring 1311, and the positioning hole 182 is arranged on the second outer ring 1312. When the first outer ring 1311 and the second outer ring 1312 are combined and mounted along the radial direction of the outer ring 131 of the spherical bearing, the positioning pin 181 is inserted into the positioning hole 182, thereby achieving fixed connection of the first outer ring 1311 and the second outer ring 1312 to form the outer ring 131 of the spherical bearing. It can be understood that, in some other embodiments, the positioning hole 182 can be arranged on the first outer ring 1311, and the positioning pin 181 can be arranged on the second outer ring 1312.

[0069] In some embodiments, the first mounting member 14 comprises a first connecting body 141 and a second connecting body 412. The first connecting body 141 is fixedly connected with the first outer ring 1311, and the second connecting body 412 is fixedly connected with the second outer ring 1312. In this way, the first connecting body 141 and the second connecting body 412 can be connected by fixing the first outer ring 1311 and the second outer ring 1312 through the third mounting assembly 18, without the need to provide other fixing assemblies for the first connecting body 141 and the second connecting body 412, thereby facilitating installation and maintenance.

[0070] Specifically, in some embodiments, the first connecting body 141 is integrally formed with the first outer ring 1311, and the second connecting body 412 is integrally formed with the second outer ring 1312. Through the above-mentioned integrated design, the number of parts is greatly reduced, the cost is reduced, and the installation and maintenance are further facilitated.

[0071] Referring to Figure 6 Specifically, in some embodiments, the second connecting body 412 is integrally formed with the inner ring 132 of the spherical bearing. Through the above-mentioned integrated design, the number of parts is greatly reduced, the cost is reduced, and the installation and maintenance are further facilitated.

[0072] Referring to Figure 2 and Figure 3In some embodiments, the connecting mechanism 10 further comprises a sliding assembly 40, which is arranged between the first to-be-connected member 20 and the first mounting member 14, and allows the first to-be-connected member 20 and the first mounting member 14 to slide along the axial direction of the outer ring 131 of the spherical bearing; and / or, the sliding assembly 40 is arranged between the second to-be-connected member 30 and the second mounting member 15, and allows the second to-be-connected member 30 and the second mounting member 15 to slide along the axial direction of the inner ring 132 of the spherical bearing.

[0073] When the sliding assembly 40 is arranged between the first to-be-connected member 20 and the first mounting member 14, the sliding assembly 40 can avoid the first to-be-connected member 20 from being connected closely with the outer ring 131 of the spherical bearing, and thus the interference between the first to-be-connected member 20 and the assembly seat body 12 during the free rotation of the first to-be-connected member 20, which leads to the smaller free rotation angle of the first to-be-connected member 20 and the weaker adaptability. When the sliding assembly 40 is arranged between the second to-be-connected member 30 and the second mounting member 15, the sliding assembly 40 can avoid the second to-be-connected member 30 from being connected closely with the inner ring 132 of the spherical bearing, and thus the interference between the second to-be-connected member 30 and the assembly seat body 12 during the free rotation of the second to-be-connected member 30, which leads to the smaller free rotation angle of the second to-be-connected member 30 and the weaker adaptability. That is, the sliding assembly 40 can increase the free rotation angle of the first to-be-connected member 20 and the second to-be-connected member 30, so as to improve the adaptability.

[0074] In some embodiments, the sliding assembly 40 comprises a first sliding groove 41, a second sliding groove 42, and a sliding rod 43, which can slide in the first sliding groove 41 and the second sliding groove 42. When the sliding assembly 40 is arranged between the first to-be-connected member 20 and the first mounting member 14, the first sliding groove 41 and the second sliding groove 42 are arranged along the axial direction of the outer ring 131 of the spherical bearing, one of the first to-be-connected member 20 and the first mounting member 14 is provided with the first sliding groove 41, and the other of the first to-be-connected member 20 and the first mounting member 14 is provided with the second sliding groove 42. When the sliding assembly 40 is arranged between the second to-be-connected member 30 and the second mounting member 15, the first sliding groove 41 and the second sliding groove 42 are arranged along the axial direction of the inner ring 132 of the spherical bearing, one of the second to-be-connected member 30 and the second mounting member 15 is provided with the first sliding groove 41, and the other of the second to-be-connected member 30 and the second mounting member 15 is provided with the second sliding groove 42. Through the cooperation of the sliding rod 43, the first sliding groove 41 and the second sliding groove 42, the first mounting member 14 and the second mounting member 15 can slide along the axial direction.

[0075] Referring to Figure 7 and Figure 8 , Figure 7 FIG. 1 shows a structural schematic diagram of a connecting mechanism 10 and a photovoltaic tracking support according to an embodiment of the present application. Figure 8The structure diagram of the connecting mechanism 10 and the photovoltaic tracking support according to another embodiment of the present application is shown. Compared with the prior art Figure 7 The second connecting piece 30 in the connecting mechanism 10 is connected closely with the inner ring 132 of the spherical bearing, Figure 8 The second connecting piece 30 in the connecting mechanism 10 is axially slidable with the inner ring 132 of the spherical bearing, so that a distance is generated between the second connecting piece 30 and the inner ring 132 of the spherical bearing, so that the second connecting piece 30 can have a larger free rotation angle and can better adapt to complex terrain. Since the first connecting piece 20 and the second connecting piece 30 at the left and right ends are independently rotatable at the contact spherical surface of the spherical bearing body 13 and the assembly seat body 12, the effect of torque release is achieved, and the first connecting piece 20 and the second connecting piece 30 can be freely rotated, which plays the role of a mandrel, so that the distance between the first connecting piece 20, the second connecting piece 30 and the spherical bearing body 13 is increased, and the stiffness of the first connecting piece 20 and the second connecting piece 30 is not affected. However, it is very advantageous for the connecting mechanism 10 to increase the free rotation angle and have higher adaptability.

[0076] At least one embodiment of the present application provides a photovoltaic tracking support, which comprises a plurality of photovoltaic assemblies arranged in sequence and the connecting mechanism 10 according to any one of the above embodiments. The photovoltaic assembly comprises a photovoltaic main beam. The outer ring 131 of the spherical bearing in the connecting mechanism 10 is connected to the photovoltaic main beam of one photovoltaic assembly.
