In a preferred embodiment of the present application, as shown in fig. 1 to 9, a photovoltaic metal tile roofing system comprises a plurality of photovoltaic tiles, wherein two sides of each photovoltaic tile are respectively provided with a first waterproof edge 110 and a second waterproof edge 120, so that rainwater can flow to the position under an eave along an area between the first waterproof edge 110 and the second waterproof edge 120 when raining. The tops of the first waterproof edge 110 and the second waterproof edge 120 are both provided with a clamping part; when laying of photovoltaic tile, adjacent photovoltaic tile is laminated through first waterproof limit 110 and second waterproof limit 120 respectively to make the mutual stack block of block portion that corresponds on first waterproof limit 110 and the second waterproof limit 120, and then can realize the quick installation of photovoltaic tile, thereby save construction cost. And, adjacent photovoltaic tile passes through the mutual block of block portion, can form the restriction resistance in the installation direction of photovoltaic tile, and then can improve the wind-resistant performance of tearing open of photovoltaic tile.

In this embodiment, as shown in fig. 1 to 3 and 5 to 8, the first waterproof edge 110 of each photovoltaic tile is provided with a connecting plate 140 on a side away from the second waterproof edge 120. So that each photovoltaic tile can fix the connection plate 140 to the roof by means of at least one fastener 400 when laying the photovoltaic tile; after the photovoltaic tiles are paved, the adjacent photovoltaic tiles can cover and shield the fastening pieces 400 and the connecting plates 140, so that rainwater can be prevented from flowing to a roof along gaps of the fastening pieces 400, and the waterproof performance of the paved photovoltaic tiles can be effectively improved. Meanwhile, the first waterproof edge 110 of the photovoltaic tile is fixed on the roof, so that the structural stability and the wind uncovering resistance of the whole photovoltaic metal tile roof system can be effectively improved.

It will be appreciated that the laterally extending connection plate 140 of the first watertight edge 110 of the photovoltaic tile is fastened to the roof by means of fasteners 400; simultaneously the waterproof limit of second 120 of photovoltaic tile can with adjacent photovoltaic tile on by fixed waterproof limit 110 through block portion stack block to the waterproof limit of first 110 and the waterproof limit of second 120 of photovoltaic tile can both be restricted in the roofing, and then can effectually guarantee the structural rigidity of photovoltaic tile, with the whole anti-wind that improves the structural stability that whole photovoltaic tile laid and the whole anti-wind that photovoltaic tile laid uncovers the performance.

It can also be understood that the first waterproof edge 110 and the second waterproof edge 120 are rib structures, so that the first waterproof edge 110 and the second waterproof edge 120 can not only play a role in guiding rainwater, but also can improve the structural strength of the first waterproof edge and the second waterproof edge, and further can structurally reinforce the photovoltaic tile in the length direction.

Specifically, as shown in fig. 1 and 5 to 8, the photovoltaic tile is laid by the following steps: firstly, one of two adjacent photovoltaic tiles is fixed with a roof through the matching of the fastener 400 and the connecting plate 140, then the second waterproof edge 120 of the other photovoltaic tile is attached to the fixed first waterproof edge 110, and at the moment, the second waterproof edge 120 is positioned on the upper surface of the first waterproof edge 110, so that the fastener 400 for fixing the first waterproof edge 110 and the connecting plate 140 are covered and shielded. And then, the process is sequentially repeated to finish the laying of the photovoltaic metal tile roof system. So that rain water can only flow along the raised sides of the first and second waterproof rims 110, 120 to the middle region of the photovoltaic tile during rain.

It should be appreciated that the fastener 400 is conventional in the art, and that common fasteners 400 are screws, bolts, and the like.

In the present embodiment, the engaging portion is formed in various ways, including but not limited to the following two ways.

The first forming method comprises the following steps: as shown in fig. 1, 2 and 5 to 8, the tops of the first waterproof rim 110 and the second waterproof rim 120 are recessed downward to form a catching portion.

Specifically, as shown in fig. 1 and 5 to 8, the engaging portion is formed with an inner cavity communicating with the outside of the photovoltaic tile. And the two engaging portions of each photovoltaic tile may be a first engaging portion 1101 and a second engaging portion 1201, respectively; the size of the inner cavity of the first engaging portion 1101 is larger than that of the second engaging portion 1201. When the adjacent photovoltaic tiles are laid, one photovoltaic tile can be clamped by the second clamping portion 1201 and the inner cavity of the first clamping portion 1101, so that the photovoltaic tiles have sufficient wind uncovering resistance along the wind uncovering direction; and meanwhile, the photovoltaic metal tile roof system after being paved has enough structural stability.

The first engaging portion 1101 is located on the top of the first waterproof edge 110, and the second engaging portion 1201 is located on the top of the second waterproof edge 120.

The second forming method: the top of the first waterproof side 110 and the second waterproof side 120 is upwardly protruded to form a catching portion.

Specifically, the clamping part is provided with an inner cavity communicated with the inner side of the photovoltaic tile. The two clamping parts of each photovoltaic tile can be a first clamping part 1101 and a second clamping part 1201 respectively; the size of the inner cavity of the first engaging portion 1101 is larger than that of the second engaging portion 1201. When the adjacent photovoltaic tiles are laid, one photovoltaic tile can be clamped by the second clamping portion 1201 and the inner cavity of the first clamping portion 1101, so that the photovoltaic tiles have sufficient wind uncovering resistance along the wind uncovering direction; and meanwhile, the photovoltaic metal tile roof system after being paved has enough structural stability.

The first engaging portion 1101 is located on the top of the second waterproof edge 120, and the second engaging portion 1201 is located on the top of the first waterproof edge 110.

It is understood that, regardless of the first forming method or the second forming method, the first engaging portion 1101 and the second engaging portion 1201 can be directly formed by a bending process. In order to avoid an excessively high installation height of the photovoltaic tile, the first forming method is preferably adopted for the forming method of the engaging portion in the present application.

It can also be understood that, in order to ensure that the first engaging portion 1101 and the second engaging portion 1201 are matched tightly, the structural size of the inner cavity of the first engaging portion 1101 needs to be matched with the structural size of the second engaging portion 1201, so as to ensure that the second engaging portion 1201 can be exactly attached to the inner cavity of the first engaging portion 1101, and thus a shaking gap generated between two adjacent photovoltaic tiles can be avoided.

In the present application, there are various specific structures for engaging the engaging portions with each other, including but not limited to the following five embodiments.

The first embodiment is as follows: as shown in fig. 7, the cross-sectional shape of the engaging portion has a rhombic structure having an opening, so that when the first engaging portion 1101 and the second engaging portion 1201 are engaged, four sides of the inner cavity of the first engaging portion 1101 need to be attached to four sides of the outer side of the second engaging portion 1201.

Example two: as shown in fig. 1, the cross-sectional shape of the engaging portion is a rhombic structure having an opening, and the adjacent sides of the cross-section of the engaging portion are in arc transition, so that when the first engaging portion 1101 and the second engaging portion 1201 are engaged, only the four outer sides of the second engaging portion 1201 are partially attached to the four inner sides of the inner cavity of the first engaging portion 1101.

Example three: as shown in fig. 5, the cross-sectional shape of the engaging portion has an arc-shaped structure having an opening, so that when the first engaging portion 1101 and the second engaging portion 1201 are engaged with each other, the inner cavity of the first engaging portion 1101 can be fitted to the outer side of the second engaging portion 1201.

Example four: as shown in fig. 6, the cross-sectional shape of the engaging portion has a pentagonal structure having an opening, so that when the first engaging portion 1101 and the second engaging portion 1201 are engaged, the multiple inner sides of the first engaging portion 1101 need to be fitted to the multiple outer sides of the second engaging portion 1201.

It is understood that, as seen from the first, second and fourth embodiments, the cross-sectional shape of the engaging portion may be any polygonal structure, and only the above-mentioned size requirement is satisfied.

Example five: as shown in fig. 8, the inner cavity of the engaging portion has an opening, and the side of the inner cavity of the engaging portion has at least one protruding structure deviating from the extending direction of the opening; therefore, when the first engaging portion 1101 and the second engaging portion 1201 are engaged with each other, the lumen side of the first engaging portion 1101 needs to be attached to the outer side of the second engaging portion 1201.

It can be understood that, in the first to fifth embodiments, a convex structure larger than an opening of the inner cavity is formed on a side portion of the inner cavity of the engaging portion, so that when the first engaging portion 1101 and the second engaging portion 1201 are engaged, wind uncovering resistance can be generated by blocking the second engaging portion 1201 in the installation direction through the opening of the first engaging portion 1101, and wind uncovering resistance after the photovoltaic tile is laid can be further ensured.

In the present embodiment, as can be seen from the molding process and the mounting manner of the engaging portion, the overall structure of the engaging portion has elasticity. That is, when the first engaging portion 1101 and the second engaging portion 1201 are engaged, the opening of the first engaging portion 1101 needs to be elastically expanded, and at the same time, the second engaging portion 1201 needs to be elastically contracted, so that the size of the contracted second engaging portion 1201 is smaller than the size of the opening of the expanded opening of the first engaging portion 1101, and it is further ensured that the second engaging portion 1201 can extend into the inner cavity of the first engaging portion 1101, and then the inner cavity of the first engaging portion 1101 and the outer side of the second engaging portion 1201 are tightly attached by elastic contraction and restoration of the opening of the first engaging portion 1101 and elastic expansion and restoration of the second engaging portion 1201.

In one embodiment of the present application, as shown in fig. 1, 5 to 8, the photovoltaic metal tile 100 roofing system further includes a plurality of sealing strips 300. After the adjacent photovoltaic tiles are laid, the plugging rubber strip 300 can be matched with the opening corresponding to the second clamping portion 1201.

It can be understood that, because the inner cavity of the clamping part has a certain depth, rainwater can flow to the inner cavity along the opening of the inner cavity when raining. And the rainwater in the inner cavity is not easy to evaporate, so that the inner cavity of the clamping part is easy to rust. Meanwhile, due to the scalability of the engaging portion, there is still a risk that the first engaging portion 1101 and the second engaging portion 1201 are released in the mounting direction after the engagement. Therefore, after the first engaging portion 1101 and the second engaging portion 1201 are engaged with each other, the sealing tape 300 can be attached to the opening of the second engaging portion 1201; the plugging rubber strip 300 can not only seal the inner cavity of the clamping part, but also ensure that the clamping part after clamping cannot stretch, so that the service life of the photovoltaic tile and the wind resistance of the photovoltaic tile can be effectively improved.

It can also be understood that, when the second forming method is adopted for the forming method of the engaging portion, since the opening direction of the engaging portion faces to the roof, rainwater cannot enter the inner cavity of the engaging portion, and the function of the plugging rubber strip 300 is only to prevent the photovoltaic tile after being laid from loosening.

Specifically, as shown in fig. 1, 4 to 8, the plugging strip 300 includes a sealing portion 310 and a pressing portion 320; the sealing portion 310 and the pressing portion 320 may have a T-shaped connection therebetween. The pressing portion 320 may be press-fitted to the opening of the engaging portion, and the sealing portion 310 may cover and seal the opening end of the engaging portion.

It is also understood that the sealing strip 300 may be made of hard material such as plastic, or soft material such as rubber. The extrusion portion 320 of the plugging rubber strip 300 and the inner cavity opening of the clamping portion need to be in interference fit, so that sufficient installation strength between the plugging rubber strip 300 and the clamping portion is ensured.

In this embodiment, as shown in fig. 1 and 4 to 8, when the engaging portion is formed to be recessed downward, the sealing portion 310 is provided to be convex, so that rainwater flows along the sealing portion 310 to the first waterproof edge 110 and the second waterproof edge 120 on both sides.

Specifically, as shown in fig. 4, the upper end surface of the sealing portion 310 may be an arc-shaped protrusion or a V-shaped protrusion.

In one embodiment of the present application, as shown in fig. 1-3 and 5-9, a photovoltaic tile includes a metal tile 100 and a photovoltaic assembly 200; the first waterproof edge 110 and the second waterproof edge 120 are respectively disposed on two sides of the metal tile 100, so that the metal tile 100 forms a mounting area 130 between the first waterproof edge 110 and the second waterproof edge, and the photovoltaic module 200 is mounted in the mounting area 130.

Specifically, the photovoltaic module 200 may be designed without a frame or with a frame, and the photovoltaic module 200 may be pre-installed with the installation area 130 of the metal tile 100 in a factory to form a desired photovoltaic tile. The photovoltaic module 200 can be mounted to the mounting region 130 by bonding or fastening. The metal tile 100 is made of materials including, but not limited to, aluminum magnesium manganese alloy, zinc magnesium aluminum alloy, aluminum-zinc alloy, and steel plate.

It is understood that the size of the photovoltaic module 200 can be selected according to actual needs, and the size of the metal tile 100 only needs to be matched with the photovoltaic module 200.

In this embodiment, as shown in fig. 9, photovoltaic wiring plugs 210 are connected to the back of the photovoltaic modules 200 mounted on each metal tile 100, and the photovoltaic wiring plugs 210 corresponding to each photovoltaic module 200 may be connected and wired to each other along the back of the metal tile 100 or the back of the ridge. Therefore, the photovoltaic wiring plug 210 can be hidden, so that the photovoltaic wiring plug 210 and the whole cable can be protected.

The foregoing has described the general principles, essential features, and advantages of the application. It will be understood by those skilled in the art that the present application is not limited to the embodiments described above, which are merely illustrative of the principles of the application, but that various changes and modifications may be made without departing from the spirit and scope of the application, and such changes and modifications are intended to be within the scope of the application as claimed.
