When the description refers to the drawings, unless otherwise specified, the same numbers in different drawings represent the same or similar elements. The contents described in the following exemplary embodiments do not represent all embodiments consistent with the present invention; on the contrary, they are merely examples of devices, products and / or methods that are consistent with some aspects of the present invention and are recorded in the claims of the present invention.

[0039] The terms used in the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the scope of protection of the present invention. The singular forms "a", "said" or "the" used in the specification and claims of the present invention are also intended to include plural forms, unless the context clearly indicates other meanings.

[0040] Please refer to Figures 1 to 7The utility model discloses a photovoltaic mounting bracket 100, which is used to mount and fix photovoltaic modules on the main beam 200 of the photovoltaic tracking bracket. The photovoltaic mounting bracket 100 includes a purlin 1, a U-shaped connector 2 and a fastener 5. The purlin 1 includes a bottom wall 11, a side wall 12 arranged around the bottom wall, and a ring-shaped top wall 13 arranged on the edge of the side of the side wall 12 away from the bottom wall 11. The bottom wall 11 and the surrounding side walls 12 form a groove space with a notch. The top wall 13 is bent outward from the top of the side wall 12 to form a ring shape, so that the overall strength of the purlin 1 is improved. The photovoltaic bracket installs the photovoltaic module through the top wall 13, and the photovoltaic mounting bracket is installed on the main beam 200 through the bottom wall 11. The two free ends of the U-shaped connector 2 are respectively connected to the bottom wall 11 by fasteners 5, and the bottom wall 11 and the U-shaped connector 2 form a straight line to form an accommodating space 104 for the main beam 200 to pass through. In this way, on the basis of the existing purlin 1, the photovoltaic mounting bracket 100 can be fixed to the main beam 200 through a U-shaped connector 2, which simplifies the structure of the mounting bracket 100, reduces production costs, and can also reduce on-site installation time and workload, thereby reducing labor costs.

[0041] Please refer to Figure 1 The purlin 1 is in the shape of a boat having a cabin 101, a bow 102 and a stern 103. The top wall 13 of the bow 102 and the brackets of the two side walls 12 of the cabin 101 are provided with reinforcing ribs 14, and the top wall 13 of the stern 103 and the two side walls 12 of the cabin 101 are provided with reinforcing ribs 14 to increase the strength of the purlin 1, avoid deformation caused by the photovoltaic module acting on the purlin 1, and reduce the risk of cracking at the edge of the purlin 1 (the bow 102 and the stern 103).

[0042] Please refer to Figures 1 to 5 The bottom wall 11 of the cabin part 101 has a recessed portion 111, and the recessed portion 111 is recessed toward one side of the top wall 13, and the recessed portion 111 is matched with the main beam 200. Specifically, the recessed portion 111 is recessed toward one side of the top wall 13. The shape of the recessed portion 111 is matched with the shape of the main beam 200 to increase the contact area between the bottom wall 11 and the outer wall of the main beam 200, reduce the stress concentration caused by the small contact area between the bottom wall 11 and the main beam 200, and improve the overall structural strength and stability of the photovoltaic mounting bracket 100 of the utility model.

[0043] In this embodiment, the recessed portion 111 includes a first horizontal surface 1111 and first curved surfaces 1112 disposed on both sides of the first horizontal surface 1111. Preferably, the two first curved surfaces 1112 are symmetrically disposed along the midline of the first horizontal surface 1111. In this embodiment, the main beam 200 includes a first horizontal wall 210, two first curved walls 220 disposed on both sides of the first horizontal wall 210, a second curved wall 230 disposed opposite to the first horizontal wall 210, and a first vertical wall 240 connecting the first curved wall 220 and the second curved wall 230. The first horizontal wall 210 is in contact with the first horizontal surface 1111, and at least a portion of the first curved wall 220 is in contact with the first curved surface 1112. In this way, the recessed portion 111 of the bottom wall 11 of the purlin 1 can replace the function of the upper pressure plate in the prior art, thereby increasing the contact area between the purlin 1 and the main beam 200 while ensuring that the purlin 1 remains stable on the top of the main beam 200. The structure is simple and the installation and production costs are reduced.

[0044] In other embodiments, the shape of the recessed portion 111 may be any other shape as long as it can match the shape of the outer wall of the main beam 200 , and there is no limitation here.

The first arc surface 321 and the second arc surface 421 are arranged opposite to each other, and the first arc surface 321 and the second arc surface 421 are respectively in contact with the corresponding first arc-shaped wall 220. This arrangement increases the contact area between the first pressing block 3, the second pressing block 4 and the main beam 200, thereby improving the stability of the photovoltaic mounting bracket 100 and reducing the stress concentration caused by the small contact area between the U-shaped connector 2 and the main beam 200.

[0048] Please refer to Figure 4 The U-shaped connector 2 further includes a main body 23 connecting the first end 21 and the second end 22. The main body 23 is flat, and the first end 21 and the second end 22 are cylindrical. Preferably, the main body 23 is U-shaped, and the main body 23 fits the second arc wall 230 to increase the contact area between the U-shaped connector 2 and the main beam 200, thereby improving the stability of the photovoltaic mounting bracket 100.
