Detailed Implementation
[0072] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
[0073] Reference Figure 1 , Figure 1 A schematic diagram of the appearance structure of a photovoltaic module installation structure is shown. The photovoltaic module installation structure includes: a photovoltaic module 10, a back frame 20, and a first connecting frame 30; the first connecting frame 30 is fixedly connected to the roof layer 40, and the back surface of the photovoltaic module 10 is fixedly connected to the back frame 20; the side of the first connecting frame 30 facing away from the roof layer 40 is provided with a first snap-fit structure 31 and a limiting member 32; the side of the back frame 20 facing the first connecting frame 30 has a second snap-fit structure 21; the second snap-fit structure 21 of the back frame 20 is engaged with the first snap-fit structure 31 of the first connecting frame 30, and after the second snap-fit structure 21 is engaged with the first snap-fit structure 31, the limiting member 32 on the first connecting frame 30 limits and fixes the second snap-fit structure 21.
[0074] In this embodiment of the invention, the roof layer 40 can be a sloping roof or a horizontal roof, and it can also be a flexible roof or a rigid roof. The photovoltaic module 10 can include photovoltaic cells, and both sides of the photovoltaic module 10 can be glass layers, or only the light-facing side can be a glass layer. The photovoltaic module 10 can further realize photovoltaic power generation while fulfilling the basic functions of roof tiles.
[0075] Reference Figure 2 In this embodiment of the utility model, the photovoltaic module installation structure can be fixedly installed on the roof layer 40. Specifically, the first connecting frame 30 can be fixedly installed on the roof layer 40, and the back frame 20 can be installed on the back surface of the photovoltaic module 10. Then, the photovoltaic module 10 is installed on the roof layer 40 through the mechanical connection between the first connecting frame 30 and the back frame 20. The first connecting frame 30 and the back frame 20 not only serve as support and connection, but also suspend the photovoltaic module 10 from the roof layer 40. The suspended space can be used for other purposes, such as installing the insulation layer, setting up drainage and heat dissipation structures, etc.
[0076] Specifically, refer to Figure 3 , Figure 3 yes Figure 2 The enlarged schematic diagram of area A shows that, in this embodiment of the invention, a first snap-fit structure 31 and a limiting member 32 are provided on the side of the first connecting frame 30 facing away from the roof layer, and a second snap-fit structure 21 (the second snap-fit structure 21 in the figure is a plate-like structure) is provided on the side of the back frame 20 facing the first connecting frame 30. In this way, the first connecting frame 30 and the back frame 20 are basically connected by the cooperation of the first snap-fit structure 31 and the second snap-fit structure 21, and further, the limiting member 32 is used to limit and fix the cooperation structure of the first snap-fit structure 31 and the second snap-fit structure 21, so that the first connecting frame 30 and the back frame 20 are limited and fixed, thereby completing the limited and fixed assembly of the photovoltaic module 10 on the roof layer 40.
[0077] Compared to related technologies that use bolts and nuts for fixing, this embodiment of the invention employs a snap-fit structure and limiting components for fixing. This method is simple and quick to install, eliminating the need for cumbersome and time-consuming bolt and nut installation. Furthermore, the limiting and fixing effect created by the snap-fit structure and limiting components prevents the photovoltaic modules from slipping or detaching, improving the stability of the roof structure. In addition, this embodiment of the invention does not require additional installation tools or auxiliary materials for installing the photovoltaic modules. Installation is completed simply by sliding the back frame of the photovoltaic module into the snap-fit structure of the first connecting frame, thereby reducing construction costs and complexity, and improving construction efficiency.
[0078] Optional, refer to Figure 3 After the second snap-fit structure 21 and the first snap-fit structure 31 are connected, the limiting member 32 protrudes 5-20mm from the surface of the first connecting frame 30.
[0079] In this embodiment of the invention, after the second snap-fit structure 21 and the first snap-fit structure 31 are connected, the limiting member 32 protrudes 5-20mm from the surface of the first connecting frame 30. The purpose of this is to ensure that the limiting member 32 effectively holds the back frame 20 after it springs up, preventing accidental slippage of the back frame 20 due to minor vibrations or thermal expansion and contraction, and to prevent excessive protrusion of the limiting member 32, which could lead to installation difficulties or plastic deformation of the spring, thereby improving the stability of the photovoltaic module in strong wind and vibration environments. The distance by which the limiting member 32 protrudes from the surface of the first connecting frame 30 can be any value among 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, and 20mm.
[0080] Optional, refer to Figure 3 The first snap-fit structure 31 includes: a first plate 311 and a second plate 312; one side of the first plate 311 is connected to the side of the first connecting frame 30 away from the roof layer; the other side of the first plate 311 is connected to one side of the second plate 312, the other side of the second plate 312 extends in a direction away from the first plate 311, and the other side of the second plate 312 has a first extension 313 extending in a direction away from the first connecting frame 30; the first plate 311 is perpendicular to the side of the first connecting frame 30 away from the roof layer 40.
[0081] In this embodiment of the present invention, the first snap-fit structure 31 includes a first plate 311, a second plate 312, and a first extension 313 connected in sequence. The first plate 311 and the second plate 312 form a bent spring sheet structure, such that the spring sheet structure and the side of the first connecting frame 30 away from the roof layer form a receiving space with an opening on one side. When mechanically assembling the back frame 20 and the first connecting frame 30, the second snap-fit structure 21 of the back frame 20 can be inserted into the receiving space from the opening to form a snap-fit engagement. In addition, the first extension 313, which is provided on the opposite side of the second plate 312 and extends in a direction away from the first connecting frame 30, can play a guiding role at the opening, so that the second snap-fit structure 21 can be inserted into the receiving space more conveniently.
[0082] The opposite side of the second plate 312 can have a certain gap with the surface of the first plate 311, and the opposite side of the second plate 312 can also abut against the surface of the first plate 311. The connection between the first plate 311 and the second plate 312, and the connection between the second plate 312 and the first extension 313, can have a smooth chamfered structure, which can reduce structural damage caused by impact.
[0083] Optional, refer to Figure 3 The back frame 20 includes a third plate 22, a fourth plate 23, and a second snap-fit structure 21; the second snap-fit structure 21 is a plate-like structure; one side of the third plate 22 is connected to one side of the fourth plate 23, and the opposite side of the fourth plate 23 is connected to one side of the second snap-fit structure 21; the third plate 22 is perpendicular to the fourth plate 23; the fourth plate 23 is perpendicular to the second snap-fit structure 21; the third plate 22 is bonded to the back surface of the photovoltaic module 10; the opposite side of the second snap-fit structure 21 is inserted between the second plate 312 and the first connecting frame 30 and abuts against the first plate 311; further refer to Figure 4 The second snap-fit structure 21 has a notch 211 on the opposite side of the first plate 311, which is used to snap-fit with the first plate 311 to form a limiting position.
[0084] In this embodiment of the invention, the back frame 20 includes a third plate 22, a fourth plate 23, and a plate-shaped second snap-fit structure 21, thereby forming a frame structure capable of supporting the photovoltaic module 10, serving to support the photovoltaic module and connect to the first connecting frame on the roof layer; wherein, the third plate 22 can be bonded to the back surface of the photovoltaic module 10, which is a convenient and quick bonding method. In one implementation, the back frame 20 can be pre-bonded to the back surface of the photovoltaic module 10 to form an assembly, and then the assembly can be connected to the first connecting frame 30, which simplifies the on-site assembly difficulty. In another implementation, the back frame 20 can be connected to the first connecting frame 30 first, and then the back surface of the photovoltaic module 10 can be bonded to the back frame 20.
[0085] Specifically, a notch 211 is provided on the opposite side of the second snap-fit structure 21 at a position corresponding to the first plate 311. The width of the notch 211 matches the width of the first plate 311. This allows the first plate 311 to snap into the notch 211 when the second snap-fit structure 21 engages with the first snap-fit structure 31, thereby limiting the position of the first plate 31 on the second snap-fit structure 21. (Refer to...) Figure 1 This structural arrangement can reduce the probability of the photovoltaic module 10 slipping along the X direction.
[0086] Optional, refer to Figure 3 and Figure 4An opening 33 is provided on the first connecting frame 30; a second plate 312 is located between the first plate 311 and the opening 33; the limiting member 32 includes: a fifth plate 321 and a sixth plate 322; one side of the fifth plate 321 is connected to the edge of the opening 33 away from the first snap-fit structure 31; the opposite side of the fifth plate 321 is connected to one side of the sixth plate 322, and the opposite side of the sixth plate 322 has a second extension 323 extending toward the first snap-fit structure 31; the second The snap-fit structure 21 is a plate-shaped structure. When one side of the second snap-fit structure 21 is inserted between the second plate 312 and the first connecting frame 30 and abuts against the first plate 311, the opposite side of the second snap-fit structure 21 (i.e., the position of the fourth plate 23 near the second snap-fit structure 21) abuts against the sixth plate 322 to form a limiting fixation. When the fifth plate 321 is pressed down so that the fifth plate 321 is flush with the side of the first connecting frame 30 away from the roof layer 40, the limiting fixation of the second snap-fit structure 21 is released.
[0087] In some embodiments, after the second snap-fit structure 21 and the first snap-fit structure 31 are connected, the sixth plate 322 is perpendicular to the side of the first connecting frame 30 that is away from the roof layer 40, and the fifth plate 321 forms a preset angle (acute angle) with the side of the first connecting frame 30 that is away from the roof layer 40.
[0088] In this embodiment of the utility model, reference is made to Figure 1 To reduce the probability of photovoltaic module 10 shifting along the Y direction, this embodiment of the invention can use the cooperation of limiting member 32 and first snap-fit structure 31 to limit the second snap-fit structure 32 that is snapped into the first snap-fit structure 31, thereby reducing the probability of photovoltaic module 10 shifting along the Y direction. Specifically, limiting member 32 is disposed in opening 33, and limiting member 32 is a spring-loaded structure composed of fifth plate 321, sixth plate 322 and second extension 323.
[0089] Reference Figure 5 When it is necessary to install the back frame 20 and the first connecting frame 30, the second snap-fit structure 21 of the frame can be used to press down the limiting member 20 protruding from the opening 33 in the Z direction, so that the fifth plate 321 of the limiting member 20 is flush with the side of the first connecting frame 30 away from the roof layer 40. Then, the frame is slid towards the direction close to the first plate 311 to form Figure 3In this state, one side of the second snap-fit structure 21 abuts against the first plate 311, and the second snap-fit structure 21 no longer exerts downward pressure on the limiting member 32 in the Z direction. Under the action of elastic potential energy, the limiting member 32 protrudes out of the opening 33, and the protruding limiting member 32 abuts against the opposite side of the second snap-fit structure 21 to form a limiting fixation. At this time, one side of the second snap-fit structure 21 abuts against the first plate 311, and the opposite side of the second snap-fit structure 21 abuts against the limiting member 32 protruding out of the opening 33, thereby the first connecting frame 30 restricts the sliding of the frame 20 in the Y direction. For the realization of the limiting function in this embodiment of the utility model, there is no need for complex bolt and nut connections. It is only necessary to slide the frame into the snap-fit-limiting structure, which reduces the difficulty of operation and improves the assembly efficiency.
[0090] The locations where the fifth plate 321 and the sixth plate 322 connect, as well as the locations where the sixth plate 322 connects to the second extension 323, can have smooth chamfered structures, which can reduce structural damage caused by collisions.
[0091] Furthermore, refer to Figure 6 When it is necessary to disassemble the connection between the back frame 20 and the first connecting frame 30, a specific disassembly wrench 50 can be used. One end of the wrench, equipped with an anchor hook structure 53, can be inserted into the interior of the first connecting frame 30 through an opening at one end. This allows the anchor hook structure 53 to hook onto the second extension 323 of the limiting member 32. Supported by the supporting protrusion 52, the handle 51 is operated to move the anchor hook structure 53 in direction P, thereby pulling the limiting member 32 so that the fifth plate 321 of the limiting member 32 is flush with the side of the first connecting frame 30 facing away from the roof layer 40. Then, refer to... Figure 7 The frame 20 can be moved along direction Q, so that the frame 20 is separated from the first connecting frame 30, thereby completing the disassembly of the back frame 20 and the first connecting frame 30. The entire disassembly process only requires simple operation with a specific disassembly wrench, avoiding the time-consuming and laborious disassembly of bolts and nuts, and improving disassembly efficiency.
[0092] In addition, in related technologies, the use of bolts and nuts to install photovoltaic modules on the roof exposes the bolts and nuts at the corresponding connection points. This allows personnel to easily disassemble the modules using simple equipment (such as a simple wrench), greatly increasing the likelihood of theft after the photovoltaic modules are disassembled.
[0093] In this embodiment of the invention, although the snap-fit connection between the back frame of the photovoltaic module and the first connecting frame on the roof layer is simple and quick, it hides the relevant connection points. Connection points that must be operated during disassembly (such as...) Figure 6The second extension 323 (the connection point hooked by the anchor hook structure 53 of the disassembly wrench 50) is hidden inside the first connecting frame. Disassembly requires the use of a disassembly wrench with a specific structure to reach into the first connecting frame. Disassembly cannot be achieved without the help of the disassembly wrench with a specific structure. The structure of the disassembly wrench is different from other common disassembly equipment, so it is difficult to imitate, thereby improving the anti-theft performance of this utility model and reducing the probability of theft after the photovoltaic module is disassembled.
[0094] Optional, refer to Figure 1 The roof layer 40 includes: a roof panel, a raised structure 41 formed by overlapping the sides of adjacent roof panels, and a folded edge 411 located on the raised structure 41; a clearance opening 301 is provided on the side of the first connecting frame 30 facing the roof panel; the length extension direction Y of the clearance opening 301 is the same as the length extension direction of the first connecting frame 30; the length extension direction Y of the raised structure 41 is perpendicular to the length extension direction X of the back frame 20, and the raised structure 41 protrudes towards the photovoltaic module 10; the first connecting frame 30 is bonded to the raised structure 41, and the folded edge 411 passes through the clearance opening 301 and is located inside the first connecting frame 30, and the length extension direction of the first connecting frame 30 is the same as the length extension direction Y of the raised structure.
[0095] In one implementation of this utility model, the roof layer 40 can be a rigid roof, i.e., the roof includes multiple rigid roof panels, adjacent roof panels overlap and are locked together to form a supporting protruding structure 41, and a folded edge portion 411 on the protruding structure 41, which is used to lock and fix the connecting side of the adjacent roof panels. In this utility model embodiment, a clearance opening 301 can be provided on the side of the first connecting frame 30 facing the roof panel, and the side of the first connecting frame 30 facing the roof panel is bonded to the protruding structure 41, so that the folded edge portion 411 passes through the clearance opening 301 and is located inside the first connecting frame 30. Firstly, bonding the first connecting frame 30 to the protruding structure 41 can significantly reduce assembly complexity and improve assembly efficiency. Secondly, the folded edge portion 411 on the protruding structure 41 passing through the clearance opening 301 and being located inside the first connecting frame 30 allows the first connecting frame 30 to protect the folded edge portion 411 within its internal shielding space, improving product quality.
[0096] Optional, refer to Figure 8 and Figure 9 The clearance opening 301 of the first connecting frame 30 has a folded edge structure 302 on both sides. The folded edge structure 302 includes a first folded edge portion 3021 protruding toward the roof panel and a second folded edge portion 3022 connected to the first folded edge portion 3021 and located at the end.
[0097] In this embodiment of the invention, for a scenario where the roof layer 40 is a rigid roof, the first connecting frame 30 can be bonded to the roof panel via adhesive. A folded edge structure 302 can be provided on the opposite sides of the clearance opening 301. The folded edge structure 302 includes a first folded edge portion 3021 protruding towards the roof panel, and a second folded edge portion 3022 connected to the first folded edge portion 3021 and located at its end. The first folded edge portion 3021 protruding towards the roof panel ensures that the adhesive layer thickness between the first connecting frame 30 and the roof panel meets expectations; that is, the thickness of the applied adhesive layer is not less than the protrusion height of the first folded edge portion 3021. The second folded edge portion 3022 prevents structural corrosion from the end, improving product quality. In this embodiment of the invention, the processing of the folded edge structure is relatively simple, reducing the difficulty of the manufacturing process.
[0098] It should be noted that, in one implementation, the back surface of the photovoltaic module can be directly bonded to the side of the first connecting frame facing away from the roof layer, thereby enabling the photovoltaic module to be deployed and installed on the roof. In this implementation, a structural scheme for the first connecting frame can be referred to... Figure 8 The side of the first connecting frame 30 facing away from the roof layer can be designed as a recessed structure in the middle. The recessed structure can be fully covered with an adhesive layer, and adhesive pads 303 are placed on the non-recessed sides. This design ensures isolation between the photovoltaic module and the first connecting frame 30, preventing arcing caused by a loose connection between the photovoltaic module and the first connecting frame 30 in the event of a broken back glass. This also facilitates rainwater drainage after the first connecting frame 30 and the photovoltaic module are installed. Furthermore, the adhesive pads 303 on the side of the first connecting frame 30 facing away from the roof layer maintain the separation between the photovoltaic module and the first connecting frame 30, preventing arcing caused by a loose connection in the event of a broken back glass. Another structural design for the first connecting frame can be referred to... Figure 9 The side of the first connecting frame 30 facing away from the roof layer can be designed as an arc structure. This allows rainwater to drain easily after the first connecting frame 30 and the photovoltaic module are installed. The rubber pad 303 on the side of the first connecting frame 30 facing away from the roof layer can ensure the isolation between the photovoltaic module and the first connecting frame 30 and prevent arcing from occurring when the photovoltaic module is loosely connected to the first connecting frame 30 in the event of a broken back glass.
[0099] Optional, refer to Figure 10 A lightning protection structure 60 is provided on the side of the first connecting frame 30 facing away from the roof layer 40. The position of the lightning protection structure 60 corresponds to the position of the gap between adjacent photovoltaic modules 10. The lightning protection structure 60 passes through the gap and protrudes from the surface of the photovoltaic module 10; further refer to Figure 11 Each lightning protection structure 60 is also equipped with an identification structure 61.
[0100] In this embodiment of the present invention, a lightning protection structure 60 (self-tapping screw, rivet, etc.) is provided on the first connecting frame 30, passing through the gap between adjacent photovoltaic modules 10, and the lightning protection structure 60 protrudes from the surface of the photovoltaic module 10 (the difference between the height of the lightning protection structure 60 and the height of the surface of the photovoltaic module 10 is greater than or equal to 3mm). This can improve the lightning protection performance of the photovoltaic roof, so that in thunderstorms, the lightning protection structure 60 can conduct the lightning that is directed at the photovoltaic module 10, and ground it by the grounding structure 63 between the first connecting frames 30, thereby protecting the safety of the photovoltaic module.
[0101] In addition, the marking structure 61 at the location of each lightning protection structure 60 can indicate the gap position between adjacent photovoltaic modules, which facilitates the installation of photovoltaic modules and thus improves assembly efficiency.
[0102] Optional, refer to Figure 12 , Figure 13 and Figure 14 The roof layer 40 includes: a roof panel 42 and a flexible filling layer 43 disposed on the side of the roof panel 42 facing the photovoltaic module 10. The photovoltaic module mounting structure also includes: a waterproof membrane layer 44; the cross-sectional structure of the first connecting frame 30 is Z-shaped (e.g., Figure 12 and Figure 13 (as shown) or I-shaped structure (such as) Figure 14 (As shown); self-tapping screws 45 pass through the first connecting frame 30, the flexible filling layer 43 and the roof panel 42 to form a connection and fixation between the first connecting frame 30 and the roof layer 40; the waterproof membrane layer 44 covers at least part of the first connecting frame 30 and covers the self-tapping screws 45.
[0103] In one implementation of this utility model, the roof layer 40 can be a flexible roof. The flexible roof can cover a rigid roof panel with a flexible filling layer 43, thereby achieving richer roof functions (such as thermal insulation). For the flexible roof, self-tapping screws 45 are used to pass through the first connecting frame 30, the flexible filling layer 43, and the roof panel 42 to form a connection and fixation between the first connecting frame 30 and the roof layer 40. Additionally, for the flexible roof, the photovoltaic module 10 can be bonded to the first connecting frame 30 (e.g., ...). Figure 12 , Figure 13 and Figure 14 As shown, the photovoltaic module can also be mechanically connected to the first connecting frame through the back frame, but this embodiment of the present invention does not specifically limit this.
[0104] Reference Figure 12 and Figure 13In the scheme shown, the cross-sectional structure of the first connecting frame 30 is Z-shaped. The two sides of the first connecting frame 30 are first installed on the flexible roof with self-tapping screws 45. The waterproof membrane layer 44 on both sides is welded to the flexible roof to wrap the self-tapping screws 45 and prevent rainwater from seeping in.
[0105] Reference Figure 14 In the scheme shown, the cross-sectional structure of the first connecting frame 30 is I-shaped. First, the waterproof membrane layer 44 is welded to the flexible roof. Then, the two sides of the first connecting frame 30 are installed on the flexible roof with self-tapping screws 45. Finally, the waterproof membrane is welded at the screw head to provide waterproof protection for the self-tapping screws.
[0106] Optional, refer to Figure 1 The number of back frames 20 and first connecting frames 30 is multiple; multiple back frames 20 are arranged at intervals along the first direction Y on the back surface of the photovoltaic module; multiple first connecting frames 30 are arranged at intervals along the second direction X on the roof layer 40; the first direction Y is perpendicular to the second direction X.
[0107] By arranging multiple back frames 20 at intervals along the first direction Y on the back surface of the photovoltaic module, and multiple first connecting frames 30 at intervals along the second direction X on the roof layer 40, each back frame 20 can be connected to multiple first connecting frames 30, making the connection structure more stable, the coverage of the connection structure wider, and improving the overall stability of the photovoltaic roof.
[0108] Optional, refer to Figure 15 The first connecting frame 30, on the side facing away from the roof layer, is also provided with a third snap-fit structure 70, which is the same as the first snap-fit structure 31; the spacing between the first snap-fit structure 31 and the third snap-fit structure 70 on the first connecting frame 30 is the same as the spacing between two adjacent back frames 20; the first snap-fit structure 31 and the limiting member 32 on the first connecting frame 30 are used to limit and fix the second snap-fit structure 21 on one back frame 20; the third snap-fit structure 70 on the first connecting frame 30 is used to cooperate and connect with the second snap-fit structure 21 on another adjacent back frame 20.
[0109] In one embodiment of this utility model, the length of the first connecting frame 30 can be relatively long, allowing it to penetrate two adjacent back frames 20, thus achieving a cooperative connection between the first connecting frame 30 and the two adjacent back frames 20. The first snap-fit structure 31 and the limiting member 32 on the first connecting frame 30 are used to limit and fix the second snap-fit structure 21 on one back frame 20; the third snap-fit structure 70 on the first connecting frame 30 is used to cooperate with the second snap-fit structure 21 on the other adjacent back frame 20. This achieves a snap-fit and limiting fixation between the back frames and the first connecting frame by using a snap-fit and limiting fixation between one back frame and one end of the first connecting frame 30, and a snap-fit and fixing between the other adjacent back frame and the other end of the first connecting frame 30. Furthermore, this cooperative connection method between the first connecting frame 30 and the two adjacent back frames 20 can reduce installation errors and improve installation accuracy.
[0110] Optional, refer to Figure 1 The photovoltaic module mounting structure also includes: multiple second connecting frames 80 with the same structure as the first connecting frame 30; the number of back frames 20 and first connecting frames 30 is multiple; the side of the second connecting frame 80 facing away from the roof layer 40 is provided with: a fourth snap-fit structure 81 with the same structure as the first snap-fit structure 31; multiple back frames 20 are arranged at intervals along the first direction Y on the back surface of the photovoltaic module 10; for two adjacent back frames 20: one back frame 20 is connected to multiple spaced first connecting frames 30, and the first snap-fit structure 31 and the limiting member 32 on the first connecting frame 30 are used to limit and fix the second snap-fit structure 21 on one back frame 20; the other back frame 20 is connected to multiple spaced second connecting frames 80, and the fourth snap-fit structure 81 on the second connecting frame 80 is used to cooperate and connect the second snap-fit structure 21 on the other back frame 20; the extension direction of the first connecting frame 30 and the second connecting frame 80 is perpendicular to the first direction Y.
[0111] In another implementation of this utility model, the lengths of the first connecting frame 30 and the second connecting frame 80 can be relatively short, allowing one first connecting frame 30 or one second connecting frame 80 to connect to a back frame 20. Specifically, for two adjacent back frames 20: one back frame 20 is connected to multiple spaced-apart first connecting frames 30, and the first snap-fit structure 31 and the limiting member 32 on the first connecting frame 30 are used to limit and fix the second snap-fit structure 21 on one back frame 20; the other back frame 20 is connected to multiple spaced-apart second connecting frames 80, and the fourth snap-fit structure 81 on the second connecting frame 80 is used to engage and connect with the second snap-fit structure 21 on the other back frame 20, thus achieving snap-fit and limiting fixation of the connecting frame to the back frame. Furthermore, the second connecting frame 80 only has the fourth snap-fit structure 81 and lacks the limiting member, which can reduce assembly complexity and improve assembly efficiency to a certain extent.
[0112] Reference Figure 6, Figure 7 and Figure 16 This utility model embodiment also provides a disassembly wrench 50, which is used to separate the back frame 20 and the first connecting frame 30 in the photovoltaic module mounting structure. One end of the disassembly wrench 50 is a handle 51, and the other end is an anchor hook structure 53. A support protrusion 52 is also provided between the handle 51 and the anchor hook structure 53. The protrusion direction of the support protrusion 52 is consistent with the extension direction of the anchor hook structure 53. The disassembly wrench 50 is used to extend into the first connecting frame 30, so that, with the support of the support protrusion 52, the handle 51 is pressed down so that the anchor hook structure 53 hooks the second extension 323 of the limiting member 32 of the first connecting frame 30, so that the fifth plate 321 of the limiting member 32 is flush with the side of the first connecting frame 30 away from the roof layer 40, thereby releasing the limiting fixation of the limiting member 32 and separating the back frame 20 and the first connecting frame 30.
[0113] Unlike related technologies that use bolts and nuts to assemble and disassemble photovoltaic modules, this method refers to... Figure 6 In this embodiment of the invention, when it is necessary to disassemble the connection between the back frame 20 and the first connecting frame 30, a specific disassembly wrench 50 can be used. One end of the wrench, equipped with an anchor hook structure 53, extends into the interior of the first connecting frame 30 through an opening at one end. This allows the anchor hook structure 53 to hook onto the second extension 323 of the limiting member 32. Supported by the supporting protrusion 52, the handle 51 is operated to move the anchor hook structure 53 in direction P, thereby pulling the limiting member 32 so that the fifth plate 321 of the limiting member 32 is flush with the side of the first connecting frame 30 facing away from the roof layer 40. Then, refer to... Figure 7 The frame 20 can be moved along direction Q, so that the frame 20 is separated from the first connecting frame 30, thereby completing the disassembly of the back frame 20 and the first connecting frame 30. The entire disassembly process only requires simple operation with a specific disassembly wrench, avoiding the time-consuming and laborious disassembly of bolts and nuts, and improving disassembly efficiency.
[0114] Although the snap-fit connection between the back frame of the photovoltaic module and the first connecting frame on the roof layer in this embodiment is simple and quick, it hides the relevant connection points. Connection points that must be operated during disassembly (such as...) Figure 6 The second extension 323 (the connection point hooked by the anchor hook structure 53 of the disassembly wrench 50) is hidden inside the first connecting frame. Disassembly requires the use of a disassembly wrench with a specific structure to reach into the first connecting frame. Disassembly cannot be achieved without the help of the disassembly wrench with a specific structure. The structure of the disassembly wrench is different from other common disassembly equipment, so it is difficult to imitate, thereby improving the anti-theft performance of this utility model and reducing the probability of theft after the photovoltaic module is disassembled.
[0115] In summary, compared to related technologies that use bolts and nuts for fixing, this embodiment of the invention employs a snap-fit structure and limiting components for fixing. This method is simple and quick to use during installation, eliminating the need for cumbersome and time-consuming bolt and nut installation. Furthermore, the limiting and fixing effect created by the snap-fit structure and limiting components prevents the photovoltaic modules from slipping or detaching, improving the stability of the roof structure. In addition, this embodiment of the invention does not require additional installation tools or auxiliary materials for installing the photovoltaic modules; installation is completed simply by sliding the back frame of the photovoltaic module into the snap-fit structure of the first connecting frame, thereby reducing construction costs and complexity, and improving construction efficiency.
