DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0034] like Figures 1 to 12 As shown, the present invention provides a photovoltaic tile frame structure, comprising: a first frame 100 and a second frame 200 that overlap each other. A first wing plate 110 and a second wing plate 120 are provided in the middle of one side of the first frame 100. The first wing plate 110 is arranged above the second wing plate 120. The first wing plate 110 and the first frame 100 are enclosed to form a first groove 112 with an upward opening, and the second wing plate 120 and the first frame 100 are enclosed to form a second groove 121 with an downward opening. A third wing plate 210 and a fourth wing plate 220 are provided on one side of the second frame 200. The third wing plate 210 is arranged above the fourth wing plate 220. The third wing plate 210 and the second frame 200 are enclosed to form a third groove 212 with an downward opening, and the fourth wing plate 220 and the second frame 200 are formed to form a fourth groove 221 with an upward opening. When the first frame 100 and the second frame 200 are overlapped, the first groove 112 and the third groove 212 are interlocked with each other, and the second groove 121 and the fourth groove 221 are interlocked with each other.

[0035] In this embodiment, the cross-sections of the first wing panel 110, the second wing panel 120, the third wing panel 210, and the fourth wing panel 220 are L-shaped. The horizontal edge of the third wing panel 210 is flush with the upper side of the second frame 200, and the horizontal edge of the fourth wing panel 220 is flush with the lower side of the second frame 200. This reduces the formation of grooves at the joint between the first frame 100 and the second frame 200, which could cause water accumulation and allow rainwater to more easily seep through the gaps at the joint.

[0036] When the first frame 100 and the second frame 200 overlap, one side of the first wing plate 110 is pressed against the second frame 200, and one side of the second wing plate 120 is pressed against the second frame 200. After being pressed, the speed of rainwater infiltration can be reduced. One side of the third wing plate 210 is pressed against the first frame 100, and one side of the fourth wing plate 220 is pressed against the first frame 100. After being pressed, the speed of rainwater infiltration can be reduced.

[0037] A first drainage groove 310 is formed by enclosing between the first wing plate 110 and the third wing plate 210, and a second drainage groove 320 is formed between the second wing plate 120 and the fourth wing plate 220. The gap between the first wing plate 110 and the second wing plate 120 and the second frame 200 enclose a third drainage groove 330.

[0038] In this embodiment, the first groove 112, the second groove 121, the third groove 212 and the fourth groove 221 are all in a C-shaped or U-shaped. The water infiltrating from the photovoltaic tile first enters the first drainage groove 310, and most of the water drains away from the first drainage groove 310. If the drainage capacity of the first drainage groove 310 is insufficient, the water continues to seep down into the third drainage groove 330 and the second drainage groove 320. By setting multiple drainage grooves, the drainage capacity is ensured, and the water infiltrating into the overlapping part is intercepted, effectively preventing water from infiltrating into the original roof.

[0039] One end of the first wing plate 110 and the second wing plate 120 away from the first frame 100 extends towards the first frame 100 to form a first limiting block 111, and one end of the second wing plate 120 and the third wing plate 210 away from the second frame 200 extends towards the second frame 200 to form a second limiting block 211. Plug blocks are also provided on both sides of the overlapping part of the first frame 100 and the second frame 200. The plug blocks are inserted into the first drainage groove 310 and / or the second drainage groove 320, and are arranged between the first limiting block 111 and the second limiting block 211. The first limiting block 111 and the second limiting block 211 can keep the plug block in the correct position, prevent the plug block from sliding up and down, and at the same time, ensure that there is enough drainage space at the ends of the first drainage groove 31 and the second drainage groove 320.

[0040] The plug block includes a front waterproof plug cover 410 and a rear waterproof plug cover 420; the front waterproof plug cover 410 is arranged at the downward end of the first drainage groove 310, and the rear waterproof plug cover 420 is arranged at the upward end of the first drainage groove 310;

[0041] The front waterproof plug cover 410 includes a first cover plate 411, a first dovetail insert 412, a first latch 413, a first boss 414 and a first cushion block 415. The first boss 414 is arranged at the lower rear portion of the first cover plate 411, the first dovetail insert 412 is arranged at the top of the first cover plate 411, and the first cushion block 415 is fixedly connected to the bottom of the first cover plate 411. Two first latches 413 are arranged at intervals along the height direction of the rear side of the first cover plate 411. The two first latches 413 are inserted into the first drainage groove 310 and the second drainage groove 320 and are located between the first limit block 111 and the second limit block 211. The first boss 414 separates the first cover plate 411 from the first frame 100 and the second frame 200, and a drainage outlet is formed between the first cover plate 411 and the first frame 100 and the second frame 200.

[0042] In this embodiment, the front waterproof plug cover 410 provides structural protection against wind pressure, provides water resistance, and provides hydrophobicity, as well as serves as a position limiter for the first and second frames 100, 200. The front waterproof plug cover 410 is tightly connected to the first and second frames 100, 200 of adjacent photovoltaic tiles via first latches 413. This design, through the position limiter provided by first latches 413, promotes a close fit at the joint between the first and second frames 100, 200 of adjacent photovoltaic panels, enhancing overall sealing and stability. The front waterproof plug cover 410 is designed with a drain port that can quickly guide and drain the water accumulated in the inner cavity formed by the overlap of the first frame 100 and the second frame 200, that is, the water in the first drainage groove 310, the second drainage groove 320, and the third drainage groove 330, effectively avoiding potential problems caused by water accumulation; at the same time, the front waterproof plug cover 410 effectively resists the direct invasion of wind pressure, preventing the large amount of water generated by wind pressure from penetrating into the first drainage groove 310, the second drainage groove 320, and the third drainage groove 330, thereby ensuring the smooth operation of the drain system and avoiding various problems that may be caused by untimely draining. A first pad 415 is provided at the lower end of the front waterproof plug cover 410. The first pad 415 can effectively prevent a large amount of water from flowing back from the surface of the first frame 100 and the second frame 200 to the back side of the photovoltaic tile.

[0043] The rear waterproof plug cover 420 includes a second cover plate 421 and a second latch 422 . Two second latches 422 are spaced apart along the height direction of the rear side of the second cover plate 421 . The second latches 422 are inserted into the first drainage groove 310 and the second drainage groove 320 .

[0044] In this embodiment, the rear waterproof plug cover 420 serves as a structural water barrier and limits the first and second frames 100, 200 of the photovoltaic modules adjacent to each other on both sides. The rear waterproof plug cover 420 is tightly connected to the first and second frames 100, 200 via a second latch 422. This design, through the latch's limiting effect, promotes a tight fit at the joint between the first and second frames 100, 200, improving overall sealing and stability. This prevents any water that may accumulate in the first, second, and third drainage grooves 310, 320, 330 between the first and second frames 100, 200 from penetrating toward the rear of the photovoltaic tile, fundamentally eliminating potential safety hazards and performance impacts caused by water leakage.

[0045] Structural grooves 130 are formed in the first frame 100 and the second frame 200. In this embodiment, the provision of the structural grooves 130 effectively reduces the weight of the first frame 100 and the second frame 200 without affecting the strength of the first frame 100 and the second frame 200.

[0046] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
