[0062] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the application and not intended to limit it. The described embodiments are only a part of the embodiments of the present application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without inventive effort are within the scope of protection of the present application.

[0063] It should be understood that a connection can be understood as a fixed connection.

[0064] See Figures 2 to 3 To achieve the above objectives, this application discloses the following technical solutions:

[0065] A photovoltaic support 10 is provided for mounting photovoltaic modules 20 on a roof 30. The photovoltaic support 10 includes a sloping beam 11, an adapter 12, a mounting component 13, and a pressing component 14. The adapter 12 overlaps the sloping beam 11 and is connected to the roof 30. The mounting component 13 is connected to the sloping beam 11. The pressing component 14 is connected to the mounting component 13 and includes a pressing part 141, which is pressed against the pressing part 141 on the surface of the photovoltaic module 20.

[0066] In the example above in this application, during assembly, the inclined beam 11 is connected to the roof 30 via the adapter 12, the mounting part 13 is connected to the inclined beam 11, and the pressing part 14 cooperates with the mounting part 13 to achieve the pressing of the photovoltaic module 20. It can be seen that the photovoltaic bracket 10 using the example of this application can realize the installation of the photovoltaic module 20, and compared with the prior art, the photovoltaic bracket 10 removes the purlin, thereby reducing the cost of the photovoltaic bracket 10.

[0067] To facilitate understanding of this solution, the following definitions are made: the inclined beam 11 includes a length direction, a width direction, and a thickness direction, all of which are perpendicular to each other. The aforementioned preset direction can be either the length direction or the width direction. This application example only illustrates the preset direction as the length direction. Figures 3 to 4b As shown.

[0068] The function of the aforementioned crimping member 14 is to crimp the photovoltaic module 20 between the crimping member 14 and the mounting member 13 to complete the positioning of the photovoltaic module 20. The crimping member 14 includes a crimping part 141, a fixing part 142 and a fastener 143 connected together, wherein the fastener 143 passes through the fixing part 142 to connect to the threaded hole 132 of the mounting member 13.

[0069] There are two pressing sections 141, which are used to press two adjacent photovoltaic modules 20 together, such as... Figure 3 As shown, this crimping member 14 is referred to as the intermediate crimping member. There is one crimping part 141, used to crimp a photovoltaic module 20, such as... Figure 4a and Figure 4b At this time, the crimping member 14 is called the edge crimping member.

[0070] It should be noted that the connection between the inclined beam 11 and the mounting part 13 can be a fastener connection, a snap-fit, a weld, etc. For ease of installation, this application uses a snap-fit ​​connection between the inclined beam 11 and the mounting part 13. Taking the snap-fit ​​connection between the inclined beam 11 and the mounting part 13 as an example:

[0071] See Figure 5a and Figure 5b The inclined beam 11 serves to support the mounting component 13 and the pressing component 14 to support the photovoltaic module 20. The inclined beam 11 includes a beam body 111, an electrode lug 112, and a snap-fit ​​part 113 connected together. The electrode lug 112 is located on both sides of the beam body 111 along its length to cooperate with the adapter 12. The snap-fit ​​part 113 is located on the first end face 1111 of the beam body 111 and engages with the mounting component 13.

[0072] The beam 111 includes a length direction, a width direction and a thickness direction. In the thickness direction, the beam 111 includes a first end face 1111 and a second end face 1112 arranged opposite to each other. In the width direction, the beam 111 includes a first side face 1113 and a second side face 1114 arranged opposite to each other. The pole lug 112 is located on the first side face 1113 and the second side face 1114.

[0073] The function of the tab 112 is to provide a force-bearing point for the adapter 12. The tab 112 includes an extension 1121 and an anti-detachment section 1132 connected together. The extension 1121 extends from the bottom of the beam 111 in a direction away from the beam 111, and the anti-detachment section 1132 extends from the extension 1121 in a direction perpendicular to the extension 1121 to form a groove 1123.

[0074] Along the length of the beam 111, the length of the lug 1123 is no greater than the length of the beam 111. When the length of the lug 1123 is equal to the length of the beam 111, the position of the adapter 12 on the pole lug 112 can be adjusted arbitrarily according to specific layout requirements; or when the length of the lug 1123 is less than the length of the beam 111, there can be multiple pole lugs 112 on one side, and the multiple pole lugs 112 are evenly arranged on the side of the beam 111.

[0075] In the diagram, the bottom of the extension 1121 and the second end face 1112 are in the same plane, so that both the extension 1121 and the second end face 1112 are in contact with the roof 30, increasing the contact area between the inclined beam 11 and the roof 30 and improving the stability of the inclined beam 11. Alternatively, in some examples, the bottom of the extension 1121 and the second end face 1112 are staggered. When the adapter 12 applies force to the tab 112, it is equivalent to forming a lever effect at the tab 112, thereby allowing the inclined beam 11 to be fixed with a relatively small force.

[0076] Any fastening structure that allows for connection to the tab 112 can be considered as an adapter 12. (See reference...) Figure 6 The adapter 12 shown in the figure includes a lap plate 121 and an expansion screw 122. The lap plate 121 has a mounting hole 1213 in the middle. The first edge 1211 of the lap plate 121 can be fastened in the ear groove 1123, and the second edge 1212 of the lap plate 121 can abut against the roof. The expansion screw 122 is installed in the mounting hole 1213 to connect with the roof.

[0077] In the figure, the length of the first edge 1211 is less than the length of the second edge 1212, and when the adapter 12 connects the inclined beam 11 to the roof 30, the second edge 1212, the outer extension 1121 and the second end face 1112 are all in contact with the roof 30.

[0078] Combination Figure 6 See Figure 7 and Figure 8 As shown in the figure, at least two transition pieces 12 are arranged on both sides of the inclined beam 11. The transition pieces 12 on both sides are symmetrically arranged to make the inclined beam 11 bear the force evenly and improve the connection stability of the inclined beam 11.

[0079] As described above, the function of the snap-fit ​​part 113 is to engage with the mounting part 13. To improve the overall applicability of the photovoltaic bracket, the mounting part 13 can also slide in a preset direction while engaging with the snap-fit ​​part 113, so as to adjust according to the arrangement position of the photovoltaic module 20. Figure 5b See Figure 9a The snap-fit ​​portion 113 includes two connecting sections 1131 and two snap-fit ​​sections 1132. The two connecting sections 1131 are arranged opposite to each other and extend from the end face of the beam 111 along the thickness direction of the beam 111. The two snap-fit ​​sections 1132 extend from the two connecting sections 1131 in a direction that brings them closer to each other. The two connecting sections 1131 and the two snap-fit ​​sections 1132 form a snap-fit ​​groove 1133. A snap-fit ​​opening 1134 that communicates with the snap-fit ​​groove 1133 is formed between the two snap-fit ​​sections 1132.

[0080] In the figure, the slot 1133 extends along the length of the beam 111, so the preset direction is the length of the beam 111; or the slot 1133 extends along the width of the beam 111, so the preset direction is the width of the beam 111.

[0081] like Figure 9b As shown, the mounting component 13 includes a base plate 131 located within the slot 1133. The base plate 131 includes a threaded hole 132, and the pressing component 14 is connected to the threaded hole 132 via a fastener 143. When assembling the photovoltaic module 20, the base plate 131 can be adjusted relative to the slot 1133 as needed. After the position is adjusted, the pressing component 14 can be connected to the threaded hole 132 to position the photovoltaic module 20.

[0082] In the width direction, the distance between the groove walls of the slot 1133 is greater than the diameter of the bayonet 1134. Therefore, the mounting component 13 may also include a guide portion 133, which is located on the upper end face of the base plate 131, inside the bayonet 1134, and abuts against the bayonet 1134. Thus, under the limiting effect of the guide portion 133, the shaking of the base plate 131 is reduced, so that the threaded hole 132 is fully exposed in the bayonet 1134, improving installation efficiency.

[0083] The aforementioned guide section 133 has a cuboid or cylindrical structure, wherein, Figure 9b The central guide section 133 has a cuboid structure. Figure 10b and Figure 11b The central guide section 133 has a cylindrical structure.

[0084] The aforementioned threaded hole 132 can penetrate the guide portion 133 to improve the strength at the location where the threaded hole 132 is provided and increase the service life.

[0085] To optimize the above solution, in some examples, the mounting component 13 further includes a limiting part 134 disposed on the guide part 133 and / or the base plate 131, the limiting part 134 abutting against and limiting the frame of the photovoltaic module 20, such as... Figure 9b and Figure 11b As shown, the limiting part 134 is used to abut and limit the photovoltaic module 20, wherein it is combined with Figure 3 See Figure 9b and 9c The limiting part 134 of the mounting part 13 includes a limiting ear 1341 and a limiting block 1342. The limiting ear 1341 is located at both ends of the guide part 133 to hook the frame of the photovoltaic module 20, and the limiting block 1342 is located between the two limiting ears 1341.

[0086] The middle limiting block 1342 mainly serves as a preliminary limiting function. The frames of two adjacent photovoltaic modules 20 are placed on both sides of the limiting block 1342. After the photovoltaic modules 20 are initially placed, the photovoltaic modules 20 are adjusted to a suitable position (drag the photovoltaic module 20 on the side that is not installed to move it together with the mounting piece 13, so that the frames of the two adjacent photovoltaic modules 20 coincide with the folded ears of the mounting piece 13. The limiting folded ears 1341 of the mounting piece 13 have a positioning function, which can accelerate the positioning and installation of the photovoltaic modules 20. Then, the pressing piece 14, the mounting piece 13 and the inclined beam 11 are connected together using fasteners 143.

[0087] Combination Figure 4b See Figure 11b and 11c The limiting part 134 is a cylindrical structure. When the limiting part 134 abuts against the previous photovoltaic module 20 during installation, it indicates that the installation is in place and the photovoltaic module 20 can be fixed.

[0088] In the structure described above, the snap-fit ​​portion 113 forms a slot 1133 to accommodate the sliding of the mounting member 13. In another example of this application, the slot 1133 is formed in the mounting member 13, such as... Figure 12a and Figure 12b As shown, the mounting component 13 includes a base plate 131, a threaded hole 132, and a slot 135, wherein the threaded hole 132 is provided through the base plate 131, and the slot 135 is provided at the end face of the base plate 131 near the inclined beam 11.

[0089] See Figure 13 and Figure 14This application also discloses a photovoltaic system, including a photovoltaic module 20 and a photovoltaic bracket 10 as described above. An adapter 12 of the photovoltaic bracket 10 is mounted on a roof, and the pressing portion 141 of the adapter 12 is pressed onto the surface of the photovoltaic bracket 10. Since the photovoltaic bracket 10 has the aforementioned effects, the photovoltaic system including the photovoltaic bracket 10 has corresponding effects, which will not be elaborated further here.

[0090] In the diagram, the photovoltaic modules 20 are arranged horizontally. At the bottom of each row of photovoltaic modules 20 are two rows of inclined beams 11, symmetrically arranged along the centerline of the photovoltaic modules 20. Each inclined beam 11 experiences the same force. (See attached diagram.) Figure 13 .

[0091] The lower surface of the inclined beam 11 coincides with the roof and is connected to the roof by several adapters 12. Under wind pressure conditions, since the second end face 1112 of the inclined beam 11 is completely coincident with the roof, the inclined beam 11 is not affected by bending moment. Under the same cross-sectional area, the load-bearing capacity is greater. Therefore, under the same working conditions, the cross-sectional area of ​​the inclined beam 11 can be reduced to a certain extent to achieve the purpose of cost reduction.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

"And / or" in this article is merely a description of the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, and B exists alone.
