[0022] A photovoltaic roof consists of photovoltaic modules and corrugated steel sheets. Typically, the connection between the load-bearing aluminum alloy frame photovoltaic modules and the corrugated steel sheets is achieved by adding an additional track beam. However, the addition of the beam increases material consumption and raises the production cost of the photovoltaic roof.

[0023] To solve the above problems, refer to Figures 1-3 , Figure 1 This illustration shows a structural diagram of a photovoltaic module, a color steel tile module, and a connecting module according to an embodiment of this application. Figure 2 This illustration shows a side view of a photovoltaic module, a color steel tile module, and a connecting module according to an embodiment of this application. Figure 3 This is a top view of a photovoltaic roof provided in an embodiment of this application.

[0024] This application provides a connecting assembly for connecting a photovoltaic module 1 to a corrugated steel tile assembly. The corrugated steel tile assembly includes multiple interconnected corrugated steel tiles 2, with adjacent corrugated steel tiles 2 connected by a standing seam structure 21. The connecting assembly includes two clamps 3, a first fixing member 4, a pressure plate 5, and two second fixing members 6. The two clamps 3 are respectively connected to two adjacent photovoltaic modules 1. Each clamp 3 includes an interconnected support portion 31 and a receiving portion 32. The receiving portion 32 is used to receive the photovoltaic module 1. The two support portions 31 of the two clamps 3 are connected to each other. A clamping cavity 33 is formed between the two clamps 3 to hold the upright locking structure 21, so that the support part 31 is connected to the color steel tile assembly; the first fixing member 4 passes through the two support parts 31 and connects the two support parts 31; the pressure plate 5 is set above the two clamps 3, and the pressure plate 5 and the two receiving parts 32 respectively form two mounting cavities 51, and the two photovoltaic modules 1 are respectively located in the two mounting cavities 51; the two second fixing members 6 correspond to the two clamps 3 respectively, and the second fixing members 6 pass through the pressure plate 5 and the receiving part 32 and connect the pressure plate 5 and the receiving part 32.

[0025] It should be understood that the photovoltaic module 1 includes a laminate and a frame, and the laminate and frame are fixed together with sealant. Multiple photovoltaic modules 1 are provided, arranged sequentially. The color steel tile assembly includes multiple color steel tiles 2, with adjacent color steel tiles 2 connected by a standing seam structure 21, which protrudes from the surface of the color steel tile 2.

[0026] The connecting assembly is used to connect the photovoltaic module 1 to the color steel tile module. The connecting assembly includes two clamps 3, each clamp 3 including a support part 31 and a receiving part 32. The support part 31 and the receiving part 32 are made of the same material and are integrally formed. The receiving part 32 is horizontally positioned below the photovoltaic module 1 and is used to receive the photovoltaic module 1. The support part 31 is vertically positioned. A clamping cavity 33 is formed between the two support parts 31 for clamping the upright locking structure 21. The upright locking structure 21 is in the clamping cavity 33 and engages with the two clamps 3, thereby connecting the clamps 3 to the color steel tile module.

[0027] The connecting assembly also includes a first fixing member 4, a pressure plate 5, and two second fixing members 6. The first fixing member 4 is detachably connected to the support part 31. The first fixing member 4 can be a bolt or other fixing member, which is not limited in this application. During installation, the upright locking structure 21 is first placed between the two support parts 31, and then the first fixing member 4 passes through the two support parts 31 to fix the two support parts 31 together.

[0028] The pressure plate 5 is located above the two clamps 3. The pressure plate 5 and the two receiving parts 32 respectively form mounting cavities 51 for mounting two photovoltaic modules 1. The pressure plate 5 is located above the photovoltaic modules 1, and the pressure plate 5 and the receiving parts 32 clamp the photovoltaic modules 1, thereby connecting the photovoltaic modules 1 to the clamps 3. Two second fixing members 6 are provided, and the two second fixing members 6 are respectively provided corresponding to the two receiving parts 32. The second fixing members 6 can be bolts or other fixing members, which are not limited in this application. During installation, the photovoltaic modules 1 are first placed between the pressure plate 5 and the receiving parts 32, and then the second fixing members 6 are passed through the pressure plate 5 and the receiving parts 32 to fix the pressure plate 5 and the receiving parts 32.

[0029] The system includes multiple connecting components, which can connect multiple photovoltaic modules 1 to the color steel tile modules.

[0030] This application connects the photovoltaic module 1 directly to the color steel tile module through a connecting component, eliminating the need for additional crossbeams, reducing the cost of crossbeam materials, and thus reducing the manufacturing cost of the photovoltaic roof.

[0031] In some optional embodiments, one support portion 31 is recessed on one side facing the other support portion 31, so that a clamping cavity 33 is formed between the two support portions 31. It can be one support portion 31 or both support portions 31 that are recessed; this application is not limited to this. In one example, one support portion 31 is recessed and engages with the upright locking structure 21 to improve the stability of the connection between the clamp 3 and the color steel tile assembly.

[0032] In some alternative embodiments, the height of the clamping cavity 33 is greater than the length of the upright locking structure 21 extending into the clamping cavity 33. This facilitates the insertion of the upright locking structure 21 into the clamping cavity 33 and enables its connection to the connecting assembly.

[0033] Reference Figure 1 and Figure 4 , Figure 4This diagram illustrates the structure of a clamp provided in an embodiment of this application. In some optional embodiments, the two support portions 31 are provided with engaging portions on their adjacent sides. One engaging portion is a protrusion 311, and the other engaging portion is a groove 312 adapted to the protrusion 311. The engaging portions are located at the end of the support portion 31 away from the color steel tile assembly, i.e., above the support portion 31. When the protrusion 311 extends into the groove 312, it can position the two support portions 31 and limit their positions, facilitating the installation of the first fixing member 4 and preventing misalignment of the two support portions 31.

[0034] Reference Figure 1 and Figure 5 , Figure 5 This diagram illustrates the structure of a pressure plate according to an embodiment of this application. In some optional embodiments, the pressure plate 5 has two limiting edges 52 protruding from one end facing the clamp 3. The two limiting edges 52 are spaced apart and form a limiting groove 521, which is used to clamp the ends of the two support parts 31 away from the corrugated steel sheet 2. The limiting edges 52 are made of the same material as the pressure plate 5 and are integrally formed with the pressure plate 5. Two limiting edges 52 are provided and spaced apart, forming the limiting groove 521. The upper ends of the two support parts 31 extend into the limiting groove 521. The limiting groove 521 further limits the position of the two support parts 31, which facilitates the installation of the first fixing member 4 and also prevents the two support parts 31 from being misaligned.

[0035] In some optional embodiments, the end of the pressure plate 5 is bent toward the photovoltaic module 1 to form a reinforcing part 53, which is used to fit the photovoltaic module 1. The upper end of the frame of the photovoltaic module 1 is inclined, and the reinforcing part 53 can fit with the upper end of the frame of the photovoltaic module 1. The setting of the reinforcing part 53 can increase the contact area between the pressure plate 5 and the photovoltaic module 1, improve the clamping effect of the pressure plate 5 and the receiving part 32 on the photovoltaic module 1, and improve the stability of the connection between the connecting component and the photovoltaic module 1.

[0036] Reference Figure 1 and Figure 6 , Figure 6 This illustration shows a structural schematic of a flexible pad provided in an embodiment of this application. In some optional embodiments, a flexible pad 8 is provided between the support portion 31 and the corrugated steel sheet 2. The flexible pad 8 serves as an isolation layer between the clamp 3 and the corrugated steel sheet 2, thereby reducing the risk of damage from contact between the clamp 3 and the corrugated steel sheet 2. The flexible pad 8 can be made of EPDM rubber strips, rubber pads, or silicone pads, etc., and this application does not impose any limitations. In one example, the flexible pad 8 is made of EPDM rubber strips, which also allows the support portion 31 to bond to the corrugated steel sheet 2, thereby improving the connection effect between the support portion 31 and the corrugated steel sheet 2.

[0037] Reference Figure 4and Figure 6 In some optional embodiments, the end of the support portion 31 facing the color steel tile 2 is provided with a "T" shaped groove 313, and the flexible pad 8 is provided with a connecting block 81 adapted to the "T" shaped groove. The connecting block 81 extends into the "T" shaped groove 313, further connecting the connecting block 81 to the support portion 31, preventing the connecting block 81 from detaching from the support portion 31, and improving the stability of the connection between the flexible pad 8 and the support portion 31.

[0038] In some optional embodiments, the flexible pad 8 is further provided with an extension 82, which conforms to the inner wall of the clamping cavity 33. The extension 82, located between the support portion 31 and the upright locking structure 21, prevents the plating on the surface of the upright locking structure 21 from being deposited under clamping force, thus protecting the upright locking structure 21. Simultaneously, it can also bond the upright locking structure 21 to the support portion 31, improving the stability of the connection between them.

[0039] Reference Figures 1-8 , Figure 7 This diagram illustrates the structure of a color steel tile assembly and purlins according to an embodiment of this application. Figure 8 This illustration shows a structural schematic diagram of a color steel tile according to an embodiment of this application. This application also includes a photovoltaic roof, comprising a color steel tile assembly, a photovoltaic module 1, and a connecting assembly as described in any of the preceding claims, the connecting assembly connecting the color steel tile assembly and the photovoltaic module 1. The color steel tile assembly includes multiple interconnected color steel tiles 2. Adjacent color steel tiles 2 are connected by a standing seam structure 21. The connecting assembly includes two clamps 3, a first fixing member 4, a pressure plate 5, and two second fixing members 6. The two clamps 3 are respectively connected to two adjacent photovoltaic modules 1. The clamps 3 include interconnected support parts 31 and receiving parts 32. The receiving parts 32 are used to receive photovoltaic modules 1. A clamping cavity 33 for clamping the standing seam structure 21 is formed between the two support parts 31 of the two clamps 3, so that the support parts 31 are connected to the color steel tile assembly. The first fixing member 4 passes through the two support parts 31 and connects the two support parts 31. The pressure plate 5 is set above the two clamps 3. The pressure plate 5 and the two receiving parts 32 respectively form two mounting cavities 51. The two photovoltaic modules 1 are respectively located in the two mounting cavities 51. The two second fixing members 6 correspond to the two clamps 3 respectively. The second fixing members 6 pass through the pressure plate 5 and the receiving parts 32 and connect the pressure plate 5 and the receiving parts 32.

[0040] This application connects the photovoltaic module 1 directly to the color steel tile module through a connecting component, eliminating the need for additional crossbeams, reducing the cost of crossbeam materials, and thus reducing the manufacturing cost of the photovoltaic roof.

[0041] Reference Figure 7 and Figure 8In some optional embodiments, the corrugated steel sheet assembly includes multiple interconnected corrugated steel sheets 2. Adjacent corrugated steel sheets 2 are connected by a standing seam structure 21. The standing seam structure 21 includes an inner seam 211, an outer seam 212, and a bracket 213. The outer seam 212 is fitted over the inner seam 211. One end of the bracket 213 is located between the inner seam 211 and the outer seam 212. The other end of the bracket 213 is used to connect with a purlin 7. The outer seam 212 is fitted over the inner seam 211, thereby connecting two adjacent corrugated steel sheets 2. One end of the bracket 213 is located between the inner seam 211 and the outer seam 212, which can improve the connection strength between the inner seam 211 and the outer seam 212. The other end of the bracket 213 is used to connect with a purlin 7, which is detachably connected by bolts, thereby connecting the corrugated steel sheet 2 and the purlin 7.

[0042] The bracket 213 is locked together with the corrugated steel sheet 2, and the bracket 213 is located between the purlin 7 and the corrugated steel sheet 2. When the purlin 7 deforms, but the corrugated steel sheet 2 does not deform, the bracket 213 solves the deformation difference between the two.

[0043] Under the action of external wind load, the roof vibrates up and down and has slight displacement, and the roof tends to move upward. The roof drives the photovoltaic module 1 and the clamp 3 to move upward. The clamp 3 drives the color steel tile 2 to move upward through the upright locking structure 21. During the movement, the support part 31 of the clamp 3 also squeezes the extension part 82 of the flexible pad 8. Since the color steel tile 2 is connected to the purlin 7, and the bracket 213 is also connected to the purlin 7, the load is finally transferred to the purlin 7 under the action and reaction forces, thus realizing the effective transfer of the load to the steel structure.

[0044] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
