[0032] To make the objects, technical solutions and advantages of the embodiments of the present application clearer, the following will be combined with the drawings in the embodiments of the present application to make a clear and complete description of the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present application. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other at will.

[0033] Solar power generation has the advantages of clean and environmental protection, wide distribution, long-term stability and the like. A solar power generation system can convert solar energy into electric energy to meet the needs of people's production and life. The solar power generation system includes a solar assembly and a frame arranged around the solar assembly and used for supporting the solar assembly. In the related art, the frame has been installed around the solar assembly (i.e. a photovoltaic panel). When the overall structure of the solar assembly and the frame is fixed on a mounting beam through a mounting assembly, the operation is often cumbersome, and the frame is prone to shaking during the installation process, which affects the structural stability of the overall solar power generation system.

[0034] To solve the above problems, the present application provides a mounting assembly. By arranging a limiting portion, the position of the frame can be determined when the frame is fixed with the mounting assembly. By arranging the free end of the hook portion to be bent in the direction of the frame, the frame can be limited when it is turned over in the installation cavity. At the same time, by arranging the horizontal distance from the free end of the hook portion to the limiting portion to be slightly greater than the width of the bottom plate of the frame, the overall structure of the solar assembly and the frame can be directly placed on the supporting portion from top to bottom without being blocked. The overall structural strength is ensured, and the installation is simple and convenient to operate.

[0035] The mounting assembly provided by the present application will be described in detail below in combination with the drawings.

[0036] It should be noted that the extension direction of the frame 10 is perpendicular to the plane where the x-axis and the y-axis in the coordinate system are located. The x-axis direction is the width direction of the frame 10 and the mounting assembly, and the y-axis direction is the height direction of the frame 10 and the mounting assembly. Figures 1 to 3 The shape of the frame 10 in the coordinate system is only used for exemplary description, and does not constitute a limitation on the range of the frame that can be fixed by the mounting assembly provided by the present application. Figures 1 to 3 An exemplary embodiment of the present application provides a mounting assembly, as shown in

[0037] Figures 1 to 5 ​As shown, the mounting assembly is used to fix the frame 1010, for example, to the mounting beam. The mounting assembly includes a support portion 100 and a pressure plate 200. The support portion 100 includes a support plate 110 and a hook portion 120. The support plate 110 includes a support surface 1121 that contacts the bottom plate 11 of the frame 10. A limiting portion 140 is provided on the support surface 1121. The limiting portion 140 protrudes from the support plate 110 to limit the frame 10. Those skilled in the art can set the shape of the limiting portion 140 according to actual needs. The cross-sectional shape of the limiting portion 140 is, for example, semi-circular, rectangular, etc., all of which are within the protection scope of this application.

[0038] A hook 120 is disposed at at least one end of the support plate 110 in the x-axis direction, and the free end of the hook 120 is bent toward the frame 10 to limit the frame 10 from flipping; Figure 4 As shown, the horizontal distance d from the free end of the hook 120 to the limiting part 140 is slightly greater than the width of the base plate 11. At least a portion of the pressure plate 200 is adapted to the shape of the frame 10. The pressure plate 200 cooperates with the support part 100 to press the frame 10. This adaptation means that a portion of the pressure plate 200 can fit against a portion of the frame 10, thereby applying force to the frame 10 to fix it in place.

[0039] In this embodiment, as Figure 3 As shown, after the pressure plate 200 and the support plate 110 are fixedly connected by the fastener 300, they will form a mounting cavity 400 for accommodating the frame 10. During the installation process, the frame 10 may flip in the mounting cavity 400 due to the action of the pressure plate 200. At this time, the hook 120 can hook the bottom plate 11 of the frame 10 to limit the movement and prevent the frame 10 from tilting or even falling out of the mounting cavity 400.

[0040] By setting the limiting part 140, the position of the frame 10 can be quickly determined when it is fixed with the mounting component. By setting the free end of the hook part 120 to bend towards the frame 10, the frame 10 can be limited when it flips in the mounting cavity 400. At the same time, by setting the horizontal distance from the free end of the hook part 120 to the limiting part 140 to be slightly greater than the width of the bottom plate 11 of the frame 10, the overall structure of the solar module and the frame 10 can be placed directly on the support part 100 from top to bottom without obstruction. This ensures the overall structural strength while making installation simple and easy to operate.

[0041] In some embodiments, such as Figures 1 to 4 As shown, the hook portion 120 includes a connecting plate 1210 and a bending plate 1220. The first end of the connecting plate 1210 is connected to the supporting plate 110, and the second end of the connecting plate 1210 is connected to the first end of the bending plate 1220. The free end of the bending plate 1220 faces the frame 10. (Refer to...)Figure 4 The vertical distance h between the free end of the bent plate 1220 and the supporting surface 1121 is greater than the thickness of the bottom plate 11. It should be noted that in the embodiment, the included angle between the connecting plate 1210 and the second plate 1120 is approximately 90°, and the plane where the free end of the bent plate 1220 is located is parallel to the plane where the second plate 1120 is located. In other embodiments, the included angle between the connecting plate 1210 and the second plate 1120 can be 60°, 100°, etc., and the free end of the bent plate 1220 is arranged at an included angle with the supporting surface 1121, which will not be described here.

[0042] When the frame 10 is deflected by the force of the pressing plate 200, it will move in the x-axis direction. By setting the vertical distance h between the free end of the bent plate 1220 and the supporting surface 1121 to be greater than the thickness of the bottom plate 11, a space is formed to accommodate the bottom plate 11 of the frame 10, which facilitates the bent plate 1220 hooking the bottom plate 11 and improves the limiting effect on the frame 10.

[0043] In some embodiments, as shown in Figure 1 , Figure 2 and Figure 4 , the supporting plate 110 includes a first plate 1110 and a second plate 1120 arranged at least one end of the first plate 1110, the hook portion 120 is connected with the second plate 1120, and the supporting surface 1121 is arranged on the second plate 1120, i.e., part of the surface of the second plate 1120 is used to contact the frame 10, and the second plate 1120 is used to support the frame 10. The first plate 1110 protrudes compared to the second plate 1120 to form the limiting portion 140, the pressing plate 200 is fixedly connected with the first plate 1110 to press the frame 10, and the first plate 1110 and the second plate 1120 are integrally formed.

[0044] In the embodiment, the first plate 1110 protrudes towards the pressing plate 200 compared to the second plate 1120 in the y-axis direction to form the limiting portion 140, thereby providing space for the installation between the pressing plate 200 and the supporting portion 100.

[0045] In an embodiment, the first plate 1110 and the second plate 1120 are flush on the side away from the frame 10, and the thickness of the first plate 1110 in the y-axis direction is greater than the thickness of the second plate 1120 in the y-axis direction to form the limiting portion 140, thereby facilitating the processing of the supporting plate 110.

[0046] In an embodiment, as shown in Figures 1 to 4As shown, on the side of the supporting plate 110 opposite to the supporting surface 1121 (i.e. the side away from the frame 10), the first plate 1110 protrudes towards the pressing plate 200 compared to the second plate 1120, so as to form a buffer space 130. By providing the buffer space 130, when the fixing assembly is impacted by external force, a buffering effect is provided, the possibility of breaking of the fixing assembly is reduced, and the structural strength of the fixing assembly is increased.

[0047] In an embodiment, as shown in Figure 1 , Figure 2 and Figure 5 , the pressing plate 200 comprises a third plate 210 and a pressing plate 220 arranged at least one end of the third plate 210, the plane where the third plate 210 is arranged is parallel to the plane where the first plate 1110 is arranged, and there is a gap between the third plate 210 and the first plate 1110 in the y-axis direction; the first plate 1110 is provided with a first through hole 1111, the third plate 210 is provided with a second through hole 2110, the pressing plate 220 abuts against the frame 10, and the fastener 300 passes through the first through hole 1111 and the second through hole 2110 to fix the frame 10. The fastener 300 is, for example, a bolt, and correspondingly, the first through hole 1111 and the second through hole 2110 are provided as threaded holes, and the operation is simple when installing.

[0048] If there is no gap between the first plate 1110 and the third plate 210, once the surface where the first plate 1110 and the third plate 210 are in contact is not flat during processing, it is easy to cause the pressing plate 200 and the supporting part 100 to not fit tightly, and further cause shaking. In the embodiment, by arranging the pressing plate 200 to comprise the third plate 210 arranged in a spaced manner with the first plate 1110, not only is a deformation space provided for the pressing plate 200 and the supporting part 100, but also the stability of installation is ensured.

[0049] In some embodiments, referring to Figures 1 to 5 , the pressing plate 220 comprises a side plate 2210 and a top plate 2220, the side plate 2210 connects the third plate 210 and the top plate 2220, and the side plate 2210 and the top plate 2220 have an included angle therebetween, the top plate 2220 abuts against the frame 10, and the included angle between the side plate 2210 and the top plate 2220 can be arranged according to the shape of the frame 10, so as to ensure that the top plate 2220 and the side plate 2210 have sufficient contact area with the frame 10 to limit the frame 10 and ensure that the frame 10 does not shake.

[0050] In some embodiments, as shown in Figure 1 , the side of the top plate 2220 abutting against the frame 10 is provided with a sawtooth stripe 2221. The sawtooth stripe 2221 increases the pressure between the top plate 2220 and the frame 10, has an anti-skid effect, and ensures the stable fixing of the frame 10.

[0051] In some embodiments, as shown in FIG. 2A, the free end of the top plate 2220 is obliquely arranged towards the second plate 1120. In this way, the top plate 2220 is prevented from being covered with rain or dust, thereby avoiding affecting the power generation of the solar module. Figures 1 to 3
