Description

Technical Field

[0001] This utility model relates to the field of photovoltaic building technology, specifically to photovoltaic module structure and photovoltaic roof. Background Technology

[0002] Photovoltaic module structures, as a green building material that combines aesthetics and functionality, can meet the market demand for green building materials and have broad market prospects. Among them, photovoltaic tiles are a product that can replace traditional roof tiles. They not only have the heat insulation, rainproofing, and durability of traditional roof tiles, but also have the ability to generate electricity.

[0003] However, existing photovoltaic tiles are generally installed using methods such as frame overlap, mold installation and bonding, bolt fixing, and profile hanging, which is a relatively cumbersome installation process and inconvenient for disassembly. In addition, when a single tile fails, the entire row of tiles needs to be removed, resulting in high replacement costs. Utility Model Content

[0004] In view of this, the present invention provides a photovoltaic module structure and a photovoltaic roof to solve the problems of existing photovoltaic tiles being cumbersome to install, inconvenient to disassemble, and resulting in high maintenance and replacement costs.

[0005] In a first aspect, the present invention provides a photovoltaic module structure, comprising: a plurality of photovoltaic units stacked from bottom to top, a supporting structure provided below the photovoltaic units, a snap-fit ​​unit provided on the supporting structure, the snap-fit ​​unit comprising a snap-fit ​​groove for snapping the photovoltaic units and a slot located above the snap-fit ​​groove, a rotatable first baffle provided inside the snap-fit ​​unit, a second baffle provided on the photovoltaic units for snapping with the first baffle, and an insert plate inserted into the slot of the next higher-level photovoltaic unit.

[0006] Beneficial Effects: The photovoltaic module structure of this utility model, by setting a snap-fit ​​unit on the supporting structure, and configuring a snap-fit ​​groove, slot, and rotatable first baffle on the snap-fit ​​unit, together with the insert plate and second baffle on the photovoltaic unit, realizes the rapid installation and independent disassembly of the photovoltaic unit, significantly reducing subsequent maintenance and replacement costs. During installation, the insert plate of the photovoltaic unit is inserted into the slot of the lower snap-fit ​​unit, and the second baffle of the photovoltaic unit is inserted into the snap-fit ​​groove of the upper snap-fit ​​unit and snaps into place with the first baffle. During disassembly, simply rotate the first baffle to disengage the snap-fit ​​between the first and second baffles, and then pull the insert plate out of the slot, simplifying the installation and disassembly process.

[0007] In one optional embodiment, the snap-fit ​​unit includes a mounting plate and a first support plate, a second support plate, and a third support plate that are sequentially spaced from bottom to top on the mounting plate. The mounting plate is fixed above the load-bearing structure. The first baffle is rotatably disposed at the end of the second support plate away from the mounting plate. The first support plate and the second support plate form the snap-fit ​​groove, and the second support plate and the third support plate form the slot.

[0008] Beneficial effects: The arrangement of the first support plate, the second support plate and the third support plate on the mounting plate forms a structurally stable snap-fit ​​groove and slot, which makes the photovoltaic unit firmly connected after installation and significantly improves the load-bearing capacity and wind uplift resistance.

[0009] In one optional embodiment, the snap-fit ​​unit is further provided with an elastic element that drives the first baffle and the second baffle to maintain snap-fit.

[0010] Beneficial effects: The elastic element can keep the first baffle and the second baffle in a stable snap-fit ​​state to ensure the installation stability of the photovoltaic unit. In addition, the snap-fit ​​state of the first baffle and the second baffle can be released by overcoming the elastic force of the elastic element, which facilitates the quick disassembly of the photovoltaic unit.

[0011] In one optional embodiment, the first baffle is rotatably connected to the second support plate via a rotating shaft; The elastic element is a torsion spring sleeved on the rotating shaft; Alternatively, one end of the elastic element is connected to the end of the first baffle away from the rotating shaft, and the other end of the elastic element is disposed at the bottom of the second support plate.

[0012] Beneficial effects: The pivot connection allows the first baffle to rotate stably and reliably. The elastic restoring force provided by the torsion spring ensures the first baffle remains in the engaged position without external force, effectively preventing accidental loosening due to vibration or external force, thus enhancing the reliability and safety of the photovoltaic unit connection. An elastic element can also be placed between the first baffle and the second support plate to adapt to different spatial and force requirements.

[0013] In one optional embodiment, the photovoltaic unit includes a photovoltaic module and a frame assembly disposed around the photovoltaic module. The frame assembly includes an upper frame located above the photovoltaic module and a lower frame located below the photovoltaic module. The second baffle is disposed at the top of the upper frame, and the insert plate is disposed at the bottom of the lower frame.

[0014] Beneficial effects: By placing the second baffle at the top of the upper frame and the insert plate at the bottom of the lower frame, the photovoltaic unit can be installed, fixed, or disassembled using only the frame components. This effectively avoids the clip-on unit blocking the photovoltaic module, reduces the risk of hot spots, and helps improve the reliability of the photovoltaic unit.

[0015] In one alternative embodiment, the bottom of the upper frame abuts against the top surface of the first support plate, and a gap is left between the upper frame and the mounting plate.

[0016] Beneficial effects: The first support plate is used to support the upper frame. A gap is left between the upper frame and the mounting plate to provide space for disassembly, so that the photovoltaic unit can be pushed up when disassembling, and the first baffle and the second baffle can be separated.

[0017] In one alternative embodiment, the bottom of the insert plate of the upper-level photovoltaic unit abuts against the top of the second support plate.

[0018] Beneficial effect: By abutting the bottom of the photovoltaic unit's insertion plate against the top of the second support plate, the photovoltaic unit can be subjected to force and installed at one end.

[0019] In one optional embodiment, a first water-blocking adhesive strip is provided between the lower frame and the next-level photovoltaic module.

[0020] Beneficial effect: A first water-blocking strip is installed between the lower frame and the next photovoltaic module to prevent rainwater from flowing back in.

[0021] In one alternative embodiment, the frame assembly further includes a left frame located to the left of the photovoltaic module and a right frame located to the right of the photovoltaic module. The photovoltaic module structure also includes snap-fit ​​strips, which snap-fit ​​with the adjacent left frame and right frame respectively.

[0022] Beneficial effects: By using snap-fit ​​strips to snap onto the adjacent left and right side frames respectively, the left and right sides of adjacent photovoltaic units can be fixed, which not only improves the installation stability of photovoltaic units, but also facilitates installation and disassembly.

[0023] In one optional embodiment, the left frame is bent to form a first card plate on the side opposite to the photovoltaic module, and the right frame is bent to form a second card plate on the side opposite to the photovoltaic module. The first card plate abuts against the second card plate, and the card strip is provided with a third card plate that inserts into the first card plate and a fourth card plate that inserts into the second card plate.

[0024] Beneficial effects: By using the first and second clips to abut against each other, and the first and third clips to insert into each other, and the second and fourth clips to insert into each other, the left and right frames can only slide along the length of the clip strip, which facilitates sliding and inserting installation, but cannot move up and down, thereby improving the wind resistance of the photovoltaic unit.

[0025] In one optional embodiment, the snap-fit ​​strip has a pressure plate extending upward toward the left frame and the right frame, and a mounting groove for installing the photovoltaic module is provided between the pressure plate and the left frame or the right frame, and a second water-blocking adhesive strip is provided below the pressure plate.

[0026] Beneficial effects: The pressure plate forms an installation groove with the left or right frame, which can limit the installation of photovoltaic modules. A second water-blocking strip is set under the pressure plate to prevent rainwater from flowing back in.

[0027] Secondly, this utility model also provides a photovoltaic roof, comprising: Roof structure; In the aforementioned photovoltaic module structure, the supporting structure is fixed to the roof structure.

[0028] Beneficial effects: Because photovoltaic roofs include photovoltaic module structures, they achieve the same effect as photovoltaic module structures. Specifically, by setting snap-fit ​​units on the load-bearing structure, and configuring snap-fit ​​slots, recesses, and rotatable first baffles on these units, along with the insert plates and second baffles on the photovoltaic units, rapid installation and independent disassembly of the photovoltaic units are achieved, significantly reducing subsequent maintenance and replacement costs. During installation, the photovoltaic unit's insert plate is inserted into the recess of the lower snap-fit ​​unit, and the second baffle is inserted into the snap-fit ​​slot of the upper snap-fit ​​unit, engaging with the first baffle. During disassembly, simply rotate the first baffle to disengage the engagement between the first and second baffles, and then pull the insert plate out of the recess, simplifying the installation and disassembly process.

[0044] The following is combined with Figures 1 to 8 The following describes embodiments of the present invention.

[0045] According to embodiments of the present invention, on the one hand, such as Figure 1 and Figure 2 As shown, a photovoltaic module structure is provided, including: a plurality of photovoltaic units 1 stacked from bottom to top, a supporting structure 2 disposed below the photovoltaic units 1, and a snap-fit ​​unit 3 disposed on the supporting structure 2. The snap-fit ​​unit 3 includes a snap-fit ​​groove 307 for snapping the photovoltaic units 1 and a slot 302 located above the snap-fit ​​groove 307, and a rotatable first baffle 301 disposed inside the snap-fit ​​unit 3. The photovoltaic units 1 are provided with a second baffle 101 that snaps into the first baffle 301, and the upper-level photovoltaic unit 1 is provided with an insert plate 102 inserted into the slot 302.

[0046] The photovoltaic module structure provided in this embodiment of the utility model, by setting a snap-fit ​​unit 3 on the supporting structure 2, and configuring a snap-fit ​​groove 307, a slot 302, and a rotatable first baffle 301 on the snap-fit ​​unit 3, in conjunction with the insertion plate 102 and the second baffle 101 on the photovoltaic unit 1, realizes the rapid installation and independent disassembly of the photovoltaic unit 1, significantly reducing subsequent maintenance and replacement costs. During installation, the insertion plate 102 of the photovoltaic unit 1 is inserted into the slot 302 of the lower snap-fit ​​unit 3, and the second baffle 101 of the photovoltaic unit 1 is inserted into the snap-fit ​​groove 307 of the upper snap-fit ​​unit 3 and snapped with the first baffle 301. During disassembly, only the first baffle 301 needs to be rotated to disengage the snap-fit ​​between the first baffle 301 and the second baffle 101, and then the insertion plate 102 can be pulled out from the slot 302, simplifying the installation and disassembly process.

[0047] Specifically, in this utility model, the "upper" and "lower" directions are as follows: Figure 1 As indicated by the arrows, the upper-level photovoltaic unit 1 refers to the adjacent photovoltaic unit 1 located above it in space. Similarly, the lower-level photovoltaic unit 1 refers to the adjacent photovoltaic unit 1 located below it in space. The supporting structure 2 can be the roof's battens or beams.

[0048] Specifically, photovoltaic unit 1 includes, but is not limited to, photovoltaic tiles.

[0049] It should be noted that the present invention does not limit the connection method between the bearing structure 2 and the snap-fit ​​unit 3. Any existing connection method can be selected as needed. For example, the snap-fit ​​unit 3 can be fixedly connected to the bearing structure 2 using fasteners, which are secure. The fasteners can be bolts or screws. Alternatively, the snap-fit ​​unit 3 can be glued to the bearing structure 2 with adhesive for easy installation.

[0050] In one embodiment, such as Figure 2 and Figure 3 As shown, the snap-fit ​​unit 3 includes a mounting plate 303 and a first support plate 304, a second support plate 305 and a third support plate 306 arranged sequentially from bottom to top on the mounting plate 303. The mounting plate 303 is fixed above the bearing structure 2. The first baffle 301 is rotatably disposed at the end of the second support plate 305 away from the mounting plate 303. The first support plate 304 and the second support plate 305 form a snap-fit ​​groove 307, and the second support plate 305 and the third support plate 306 form a slot 302.

[0051] A first support plate 304, a second support plate 305, and a third support plate 306 are arranged on the mounting plate 303 to form a structurally stable snap-fit ​​groove 307 and slot 302, which makes the photovoltaic unit 1 firmly connected after installation and significantly improves its load-bearing capacity and wind uplift resistance.

[0052] Specifically, the mounting plate 303, the first support plate 304, the second support plate 305, and the third support plate 306 can be integrally formed for easy installation and use. One side of the mounting plate 303 can be fixed to the load-bearing structure 2 with screws, and the first support plate 304, the second support plate 305, and the third support plate 306 are all located above the load-bearing structure 2.

[0053] It should be noted that this embodiment of the utility model does not restrict the rotational connection method between the first baffle 301 and the second support plate 305, and any existing structure can be selected as needed.

[0054] In one embodiment, such as Figure 3 and Figure 4 As shown, the first baffle 301 is rotatably connected to the second support plate 305 via a rotating shaft 6. This connection via the rotating shaft 6 enables the first baffle 301 to rotate stably and reliably.

[0055] Furthermore, the second support plate 305 has a downwardly folded flange on the side away from the mounting plate 303, and the pivot 6 is located in the mounting space formed by the flange and the second support plate 305.

[0056] In one embodiment, the snap-fit ​​unit 3 is further provided with an elastic member 308 that drives the first baffle 301 and the second baffle 101 to maintain a snap-fit. The elastic member 308 can keep the first baffle 301 and the second baffle 101 in a stable snap-fit ​​state to ensure the installation stability of the photovoltaic unit 1. In addition, the snap-fit ​​state of the first baffle 301 and the second baffle 101 can be released by overcoming the elastic force of the elastic member 308, which facilitates the quick disassembly of the photovoltaic unit 1.

[0057] It should be noted that the present invention does not limit the structure of the elastic element 308, and any existing structure can be selected as needed.

[0058] In one embodiment, such as Figure 3 As shown, the elastic element 308 is a torsion spring sleeved on the rotating shaft 6, allowing the first baffle 301 to achieve elastic reset rotation. Utilizing the elastic restoring force provided by the torsion spring, the first baffle 301 can remain in the snap-fit ​​position without external force intervention, effectively preventing accidental loosening due to vibration or external force, thus enhancing the reliability and safety of the photovoltaic unit 1 connection. During the insertion of the photovoltaic unit 1 into the snap-fit ​​slot 307, the second baffle 101 first overcomes the spring force of the torsion spring, causing the first baffle 301 to flip. Then, the first baffle 301 and the second baffle 101 abut against each other, achieving a snap-fit ​​fixation. When it is necessary to disassemble the photovoltaic unit 1, it is only necessary to overcome the spring force of the torsion spring, rotate the first baffle 301 upwards, so that the first baffle 301 and the second baffle 101 are no longer abutting, and then pull out the photovoltaic unit 1.

[0059] In one embodiment, such as Figure 4 As shown, one end of the elastic element 308 is connected to the end of the first baffle 301 away from the rotating shaft 6, and the other end of the elastic element 308 is disposed at the bottom of the second support plate 305. The elastic element 308 is disposed between the first baffle 301 and the second support plate 305, which can adapt to different spatial and force requirements. In this case, the elastic element 308 can be a tension spring.

[0060] In one embodiment, such as Figure 2 , Figure 5 and Figure 6 As shown, the photovoltaic unit 1 includes a photovoltaic module 103 and a frame assembly 104 disposed around the photovoltaic module 103. The frame assembly 104 includes an upper frame 1041 located on the upper side of the photovoltaic module 103 and a lower frame 1042 located on the lower side of the photovoltaic module 103. A second baffle 101 is disposed at the top of the upper frame 1041 and an insert plate 102 is disposed at the bottom of the lower frame 1042.

[0061] The frame assembly 104 protects the photovoltaic module 103 from loosening or deformation due to external wind pressure, rain, snow, or other heavy pressure. The second baffle 101 is positioned at the top of the upper frame 1041, and the insert plate 102 is positioned at the bottom of the lower frame 1042. The photovoltaic unit 1 can be installed, fixed, or disassembled using only the frame assembly 104. The photovoltaic module 103 does not participate in the snap-fit ​​connection with the snap-fit ​​unit 3, effectively preventing the snap-fit ​​unit 3 from obstructing the photovoltaic module 103, reducing the risk of hot spots, and improving the reliability of the photovoltaic unit 1.

[0062] Furthermore, in one embodiment, such as Figure 2 As shown, the bottom of the upper frame 1041 abuts against the top surface of the first support plate 304, and a gap is left between the upper frame 1041 and the mounting plate 303. The first support plate 304 is used to support the upper frame 1041, and the gap between the upper frame 1041 and the mounting plate 303 is used to provide disassembly space so that the photovoltaic unit 1 can be pushed upward when disassembled, and the first baffle 301 and the second baffle 101 can be separated.

[0063] Furthermore, in one embodiment, such as Figure 2 and Figure 3 As shown, the bottom of the insertion plate 102 of the upper-level photovoltaic unit 1 abuts against the top of the second support plate 305. By abutting the bottom of the insertion plate 102 of the photovoltaic unit 1 against the top of the second support plate 305, one end of the photovoltaic unit 1 is subjected to force and installed.

[0064] Furthermore, in one embodiment, such as Figure 2As shown, a first water-blocking strip 105 is provided between the lower frame 1042 and the next-level photovoltaic module 103. The first water-blocking strip 105 is provided between the lower frame 1042 and the next-level photovoltaic module 103 to prevent rainwater from flowing back in.

[0065] In one embodiment, such as Figures 5 to 8 As shown, the frame assembly 104 also includes a left frame 1043 located to the left of the photovoltaic module 103 and a right frame 1044 located to the right of the photovoltaic module 103. The photovoltaic module structure also includes a snap-fit ​​strip 4, which snaps into the adjacent left frame 1043 and right frame 1044 respectively. By using the snap-fit ​​strip 4 to snap into the adjacent left frame 1043 and right frame 1044 respectively, the left and right sides of the adjacent photovoltaic unit 1 are fixed, which not only improves the installation stability of the photovoltaic unit 1, but also facilitates installation and disassembly.

[0066] Furthermore, in one embodiment, such as Figure 7 As shown, the left frame 1043 is bent at the side opposite to the photovoltaic module 103 to form a first retaining plate 1045, and the right frame 1044 is bent at the side opposite to the photovoltaic module 103 to form a second retaining plate 1046. The first retaining plate 1045 and the second retaining plate 1046 abut against each other. The retaining strip 4 is provided with a third retaining plate 401 that inserts into the first retaining plate 1045 and a fourth retaining plate 402 that inserts into the second retaining plate 1046. By utilizing the abutment between the first retaining plate 1045 and the second retaining plate 1046, and the insertion of the first retaining plate 1045 into the third retaining plate 401 and the second retaining plate 1046 into the fourth retaining plate 402, the left frame 1043 and the right frame 1044 can only slide along the length of the retaining strip 4, which facilitates sliding insertion and installation, but prevents vertical movement, thereby improving the wind resistance of the photovoltaic unit 1.

[0067] Specifically, such as Figure 7 As shown, the first clip plate 1045 and the second clip plate 1046 are bent in opposite directions to form barbs, and the third clip plate 401 and the fourth clip plate 402 are bent in the same direction to form another barb. The two sets of barbs are interlocked with each other and have gaps to facilitate installation and disassembly. They also ensure that the adjacent left frame 1043 and right frame 1044 slide along the length of the clip strip 4 and cannot move up or down.

[0068] Furthermore, after the first card plate 1045 is inserted into the third card plate 401, and after the second card plate 1046 is inserted into the fourth card plate 402, wedge blocks can be inserted into the gap between the first card plate 1045 and the third card plate 401, and wedge blocks can be inserted into the gap between the second card plate 1046 and the fourth card plate 402 to form an interference fit, further enhancing the wind resistance.

[0069] Furthermore, in one embodiment, such as Figure 7As shown, the snap-fit ​​strip 4 has a pressure plate 404 extending upward toward the left frame 1043 and the right frame 1044. A mounting groove for installing the photovoltaic module 103 is provided between the pressure plate 404 and the left frame 1043 or the right frame 1044. A second water-blocking adhesive strip 403 is provided below the pressure plate 404. The pressure plate 404 and the left frame 1043 or the right frame 1044 form a mounting groove, which can limit the installation of the photovoltaic module 103. The second water-blocking adhesive strip 403 is provided below the pressure plate 404 to prevent rainwater backflow.

[0070] It should be noted that the first water-blocking strip 105 and the second water-blocking strip 403 can be made of any existing material, such as silicone.

[0071] According to an embodiment of the present invention, on the other hand, as... Figure 1 As shown, a photovoltaic roof is also provided, including: a roof structure 5 and the aforementioned photovoltaic module structure, with a supporting structure 2 fixed on the roof structure 5.

[0072] Because the photovoltaic roof includes a photovoltaic module structure, it has the same effect as the photovoltaic module structure. Specifically, by setting a snap-fit ​​unit 3 on the supporting structure 2, and configuring a snap-fit ​​groove 307, a slot 302, and a rotatable first baffle 301 on the snap-fit ​​unit 3, in conjunction with the insertion plate 102 and the second baffle 101 on the photovoltaic unit 1, the photovoltaic unit 1 can be quickly installed and independently disassembled, significantly reducing subsequent maintenance and replacement costs. During installation, the insertion plate 102 of the photovoltaic unit 1 is inserted into the slot 302 of the lower snap-fit ​​unit 3, and the second baffle 101 of the photovoltaic unit 1 is inserted into the snap-fit ​​groove 307 of the upper snap-fit ​​unit 3, snapping with the first baffle 301. During disassembly, simply rotate the first baffle 301 to disengage the snap-fit ​​between the first baffle 301 and the second baffle 101, and then pull the insertion plate 102 out of the slot 302, simplifying the installation and disassembly process.
