The frame 1 has a main body connecting structure for mounting a photovoltaic module main body. The connecting piece 2 comprises a pressing block 26 and a lower hook portion 22.

[0036] The pressing block 26 presses the frame 1 downward to position in the up-down direction, and the friction force generated by the provided pressing force can also position the frame 1 in the first direction, thereby fixing the frame 1. The lower hook portion 22 comprises a connecting arm 221 and a limiting arm 222 fixed to one end of the connecting arm 221, the connecting arm 221 extends towards the frame 1 along the first direction, and part of the structure of the limiting arm 222 extends downward beyond the connecting arm 221. The lower hook portion 22 can specifically be L-shaped, J-shaped, T-shaped, etc. The lower hook portion 22 is fixed to the side surface of the pressing block 26 in the first direction (i.e. left-right direction), and the side surface of the frame 1 in the first direction is provided with a limiting groove 14, and the limiting groove 14 comprises a first side wall 17 and a second side wall 11 in the first direction along the direction away from the pressing block 26, and the limiting arm 222 extends downward into the limiting groove 14. In the first direction, the limiting arm 222 abuts against the second side wall 11, and there is a movement distance 15 between the limiting arm 222 and the first side wall 17, and at the same time, the limiting arm 222 blocks the first side wall 17 on one side in the first direction, i.e. the partial area of the limiting arm 222 in the first direction parallel to the projection of the first side wall 17 is located on the first side wall 17, so as to limit the movable distance of the first side wall 17 away from the pressing block 26 by the limiting arm 222. The movement distance 15 can be any value between 0 and 5 mm. Figure 1

[0037] ​In use, the pressing block 26 can press the frame 1, the limiting arm 222 extends into the limiting groove 14 of the frame 1, and the limiting arm 222 can limit the first side wall 17 in the first direction to prevent the frame 1 from slipping in the first direction, thereby improving the reliability of the fixation of the frame 1. In addition, because of the movement distance 15 between the first side wall 17 and the limiting arm 222, when the photovoltaic module is deformed due to bearing high load and drives the frame 1 to deform, because of the existence of the movement distance 15, the frame 1 can adaptively slide a certain distance in the first direction when bearing the load (specifically, the friction force caused by the pressure of the pressing block 26 can be overcome), thereby reducing the extrusion force between the connecting piece 2 and the frame 1, which is beneficial to ensure the bearing capacity and prolong the service life. In addition, through the cooperation of the limiting arm 222 and the first side wall 17, the frame 1 can be pulled to prevent the frame 1 from slipping excessively and slipping.

[0038] Of course, for the first side wall 17 and the second side wall 11, in addition to the embodiment in which only the first side wall 17 and the limiting arm 222 are gap-set in the first direction in the present embodiment, in other embodiments, only the second side wall 11 and the limiting arm 222 can be gap-set in the first direction; or the first side wall 17 and the second side wall 11 and the limiting arm 222 are all gap-set in the first direction, which can also limit the movement distance 15 of the frame 1 relative to the pressing block 26.

[0039] As shown in Figure 1 , the side surface of the pressing block 26 in the first direction is provided with a lower hook installation groove 24, the connecting arm 221 is inserted and fixed in the lower hook installation groove 24 in the first direction, and the depth of the insertion of the connecting arm 221 into the lower hook installation groove 24 is adjustable. At this time, the movement distance 15 can be adjusted through the cooperation of the lower hook part 22 and the lower hook installation groove 24, which is good in adaptability. Of course, in other embodiments, as shown in Figure 5 , the lower hook part 22 and the pressing block 26 can also be fixed as a whole, which can be integrally formed.

[0040] As shown in Figure 1 and Figure 2 , the connecting arm 221 and the lower hook installation groove 24 are connected through tooth surface cooperation. Specifically, the top surface of the lower hook installation groove 24 has a lower tooth surface, and the top surface of the connecting arm 221 has an upper tooth surface. The teeth of the upper tooth surface and the lower tooth surface are arranged in the first direction. In installation, the lower hook part 22 is first slid into the lower hook installation groove 24 according to the required movement distance 15, and the upper tooth surface of the lower hook part 22 is restrained by the lower tooth surface of the lower hook installation groove 24.

[0042] As shown in Figure 1 , the second side wall 11 gradually deviates from the pressing block 26 in the downward direction; the limiting arm 222 is an inclined surface that cooperates with the second side wall 11 and is away from the side surface of the pressing block 26 in the first direction, has a guiding effect, can facilitate installation, and the frame 1 is better stressed. Of course, in other embodiments, as shown in the embodiment of Figure 5 , the second side wall 11 can also be a plane, and can also be a stepped surface or other shapes.

[0043] As shown in Figure 1 , the top end of the pressing block 26 protrudes in the first direction and is provided with a pressing plate 23, which presses the top of the frame 1, and the pressing plate 23 is arranged above the lower hook portion 22, and the frame 1 is pressed by the pressing plate 23, which is simple in structure and convenient to assemble.

[0044] As shown in Figure 1 , the pressing block 26 includes two side plates 21 arranged in sequence along the first direction, a connecting plate 25 located between the two side plates 21, and a bottom plate 27 located between the two side plates 21. The pressing plate 23 is located on the side plate 21, and the bottom plate 27 is located below the connecting plate 25, and the lower hook portion 22 is connected to the bottom plate 27, which is simple in structure and convenient to process. At this time, the lower hook installation slot 24 is opened in the bottom plate 27 to connect the lower hook portion 22. Among them, each structure in the pressing block 26 is fixed as a whole, which can be integrally formed.

[0045] As shown in Figure 1 , the connecting piece 2 is symmetrically arranged relative to a preset plane perpendicular to the first direction, and can be connected to one frame 1 on each side in the first direction, and has good structural stability.

[0046] As shown in Figure 1As shown, the main body connecting structure includes a main body mounting groove 12 provided on the side of the frame 1 away from the connecting piece 2 in the first direction. The main body mounting groove 12 is used to mount the clamped photovoltaic module main body, including photovoltaic glass, EVA adhesive film, battery piece, and filled sealing silica gel. The frame 1 is provided with a box-shaped frame 13 having an inner cavity below the main body mounting groove 12. The box-shaped frame 13 is provided with a connecting hook 16 on the side close to the connecting piece 2 in the first direction. The first side wall 17 is the side wall of the connecting hook 16 away from the connecting piece 2 in the first direction. The second side wall 11 is the side wall of the box-shaped frame 13 facing the connecting piece 2, and the second side wall 11 extends downward from the main body mounting groove 12 to the connecting hook 16, which has simple structure and good stability. Specifically, the connecting hook 16 is upwardly turned at the end away from the box-shaped frame 13. At this time, a limiting groove 14 is formed at the bottom of the side of the frame 1 in the first direction. In other embodiments, it can also be formed in the middle of the frame 1, for example, Figure 1 As shown, the connecting hook 16 is attached to the pressing block 26 in the first direction, which can improve the stability of the installation of the frame 1.

[0047] During installation, the lower hook portion 22 of the connecting piece 2 is first horizontally placed into the limiting groove 14 of the frame 1. The side surface of the pressing block 26 in the first direction is attached to the frame 1. Then the pressing block 26 is placed down. The pressing plate 23 at the upper end of the pressing block 26 presses the frame 1, and the lower hook portion 22 at the lower end hooks the frame 1, with a certain gap between them to allow the frame 1 to slide laterally when bearing load.

[0048] As shown, Figures 2 to 4 The photovoltaic module mounting structure further includes a purlin 3 below the connecting piece 2. A lower baffle 5 is provided below the purlin 3. The two connecting rods of the first U-shaped bolt 4 pass through the connecting piece 2 and are fixedly connected to the lower baffle 5 through the two sides of the purlin 3. The two connecting rods of the first U-shaped bolt 4 can pass between the two lower hook mounting grooves 24 of the connecting piece 2 in the first direction to avoid affecting the installation of the lower hook portion 22. After the connecting piece 2 and the frame 1 are preassembled, the first U-shaped bolt 4 is sequentially threaded downward through the pressing block bolt hole of the connecting piece 2, the two sides of the purlin 3, the lower baffle 5, the two side flat washers 6, the spring washers 7, and then tightened with the nut 8. The connecting piece 2 and the frame 1 are attached in the first direction, and the frame 1 is fastened to the purlin 3 through the connecting piece 2.

[0049] The photovoltaic module mounting structure provided by the embodiment has the advantages of simple installation and good load performance, and is suitable for high-load photovoltaic modules. During installation, the photovoltaic module is placed on the purlin 33, the connecting piece 22 is placed between the frames 1 of the two photovoltaic modules, the height of the lower hook portion 222 is slightly higher than the first side wall 17 of the frame 1, then the lower hook portion 222 is placed into the limiting groove 14 along the second side wall 11, the lower hook portion 22 on the other side is aligned with the limiting groove 14 of the other frame 1 through the same operation, the inclined surface of the connecting piece 2 is attached to the second side wall 11 of the frame 1 after the other photovoltaic module is pulled, the pressing block 26 is pressed down, and the pressing plate 23 of the connecting piece 2 is pressed against the frame 1. At this time, the lower hook portion 222 is in contact with the limiting groove 14 of the frame 1 in the up-down direction, the contact can increase friction and reduce the slippage of load deformation, and the contact can also be omitted.

[0050] When the photovoltaic module deforms, the frame 1 slides a certain distance, and the movable distance 15 between the lower hook portion 22 and the first side wall 17 is 0 mm, the constraint is performed, the continuous sliding of the frame 11 of the photovoltaic module is limited, the deformation form of the whole module is changed, and the load of the module is improved.
