Detailed implementation manners

[0063] Hereinafter, exemplary embodiments of the present invention will be described in more detail with reference to the drawings. Although the exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present invention can be more thoroughly understood and the scope of the present invention can be fully conveyed to those skilled in the art.

[0064] In a first aspect, an embodiment of the present invention discloses a photovoltaic tile, and the structure of the photovoltaic tile has the following embodiments.

[0065] Embodiment 1

[0066] Refer to Figures 1 to 4, an embodiment of the present utility model discloses a photovoltaic tile, which includes a photovoltaic laminate 3 and a frame body 4. The frame body 4 includes a laminate mounting portion 41 formed integrally. The photovoltaic laminate 3 is mounted on the laminate mounting portion 41; the frame body 4 further includes a lapping structure 42 connected to the periphery of the laminate mounting portion 41. The lapping structure 42 is used for lapping with the lapping structure 42 in an adjacent photovoltaic tile; the lapping structure 42 includes a first lapping structure 421 and a second lapping structure 422 respectively located on both sides of the laminate mounting portion 41 along a first direction. The first lapping structure 421 and the second lapping structure 422 are matched and have different structures. The first lapping structure 421 and the second lapping structure 422 are respectively used for lapping with the second lapping structure 422 and the first lapping structure 421 in an adjacent same-type photovoltaic tile; the lapping structure 42 further includes two second side lapping structures respectively located on both sides of the laminate mounting portion 41 along a second direction. The first direction intersects with the second direction. The two second side lapping structures have the same structure. The second side lapping structure is used for lapping with the second side lapping structure in an adjacent different-type photovoltaic.

[0067] Specifically, the photovoltaic tile can be applied to the roofs and facades of application scenarios such as industrial and commercial buildings, household buildings, and carports. The photovoltaic tile can directly replace traditional roof tiles and can be directly used as photovoltaic building materials. The photovoltaic laminate 3 can include a glass cover plate, an upper encapsulation film, a battery string group, a lower encapsulation film, and a backplane arranged in sequence. The photovoltaic laminate 3 can convert solar energy into electrical energy. The material of the frame body 4 can be aluminum alloy, stainless steel, etc.

[0068] The photovoltaic laminate 3 can be bonded to the laminate mounting portion 41, or the photovoltaic laminate 3 can be fixed to the laminate mounting portion 41 through a pressing strip. The photovoltaic laminate 3 is preferably bonded to the laminate mounting portion 41 to ensure the stability and sealing performance of the installation of the photovoltaic laminate 3.

[0069] When assembling the photovoltaic tile, the photovoltaic laminate 3 is installed on the laminate mounting portion 41. When multiple photovoltaic tiles are lapped to form a photovoltaic system, the lapping of the lapping structure 42 in the photovoltaic tile itself can realize the lapping with the lapping structure 42 in an adjacent photovoltaic tile.

[0070] The laminate mounting portion 41 is preferably integrally formed with the lapping structure 42. The laminate mounting portion 41 and the lapping structure 42 can be integrally formed by a die-casting process. Integral forming can ensure a more firm connection between the laminate mounting portion 41 and the lapping structure 42, reduce structural weaknesses caused by loose connection, thereby improving the strength and stability of the overall structure, and facilitating the improvement of the strength and waterproof performance of the entire photovoltaic tile; in addition, integral forming cancels the assembly step of the laminate mounting portion 41 and the lapping structure 42, thereby simplifying the production process and improving the production efficiency.

[0071] The first direction is preferably perpendicular to the second direction. The first direction can be the length direction of the photovoltaic tile, and the first direction can be referred to Figure 1 and Figure 3 the direction indicated by arrow A in Figure 2 and Figure 4 . The second direction can be the width direction of the photovoltaic tile, and the second direction can be referred to

[0072] the direction indicated by arrow B in

[0073] . The photovoltaic tile is divided into a first photovoltaic tile 1 and a second photovoltaic tile 2. Adjacent photovoltaic tiles of the same type refer to two adjacent first photovoltaic tiles 1 or two adjacent second photovoltaic tiles 2, and adjacent photovoltaic tiles of different types refer to the adjacent first photovoltaic tile 1 and the second photovoltaic tile 2. Both of the two second-side lapping structures in the same photovoltaic tile have lapping grooves, and the opening directions of the lapping grooves of the two second-side lapping structures are the same. The opening directions of the lapping grooves of the two side lapping structures can both be downward, and the opening directions of the lapping grooves of the two side lapping structures can also both be upward.

[0074] Both the first lapping structure 421 and the second lapping structure 422 have lapping grooves, and the opening direction of the lapping groove of the first lapping structure 421 is opposite to the opening direction of the lapping groove of the second lapping structure 422. For example, the first lapping structure 421 has a first lapping groove 4211 with an upward opening, and the second lapping structure 422 has a second lapping groove 4221 with a downward opening. When two adjacent photovoltaic tiles of the same type are lapped along the first direction, only the second lapping structure 422 needs to be buckled on the first lapping structure 421.

[0073] In the embodiment of the present utility model, the entire lamination installation part 41 is integrally formed. Compared with the existing four frames around the lamination being separately produced, the production process of the lamination installation part 41 is simplified, thereby improving the production efficiency and production capacity of the lamination installation part 41. In addition, when assembling the photovoltaic tile, only the photovoltaic lamination 3 needs to be installed on the lamination installation part 41. Compared with the existing four frames being separately assembled around the lamination, the assembly process of the photovoltaic tile is simplified, and further the assembly efficiency of the photovoltaic tile can be improved. In addition, adjacent photovoltaic tiles can be lapped together through the lapping structure 42, so that the photovoltaic tile can be directly used as a photovoltaic building material, and the lapping installation form is reliable and stable, improving the waterproof performance and strength of the photovoltaic system composed of multiple photovoltaic tiles. In addition, through the matching and different structures of the first lapping structure 421 and the second lapping structure 422, the lapping of two adjacent photovoltaic tiles of the same type along the first direction can be realized; through the two second-side lapping structures, the lapping of two adjacent photovoltaic tiles of different types along the second direction can be realized.

[0074] In a preferred embodiment of the present utility model, the laminate mounting portion 41 is a rectangular mounting plate; alternatively, the laminate mounting portion 41 includes a plurality of mounting strips, and the plurality of mounting strips include at least one first mounting strip extending in a first direction and at least one second mounting strip extending in a second direction, the first direction intersecting the second direction, and at least one first mounting strip intersecting at least one second mounting strip to form a plurality of hollow areas.

[0075] Specifically, the number of the first mounting strips can be one, two, three, etc., and the number of the second mounting strips can be one, two, three, etc. Preferably, the number of the first mounting strips is two, and the number of the second mounting strips is two. The two first mounting strips and the two second mounting strips intersect to form a grid-like structure. At this time, the two first mounting strips and the two second mounting strips intersect to form nine hollow areas. The shape of the hollow areas is preferably rectangular. When the laminate mounting portion 41 includes a plurality of mounting strips and at least one first mounting strip intersects at least one second mounting strip to form a plurality of hollow areas, it is beneficial to the heat dissipation of the photovoltaic tile while ensuring the installation stability of the photovoltaic laminate 3.

[0076] Referring to Figure 1 、 Figure 3 and Figure 6 In a preferred embodiment of the present utility model, the first overlapping structure 421 has a first overlapping groove 4211 with an upward opening, and the second overlapping structure 422 has a second overlapping groove 4221 with a downward opening.

[0077] The opening direction of the first overlapping groove 4211 in the first overlapping structure 421 is opposite to the opening direction of the second overlapping groove 4221 in the second overlapping structure 422, which is beneficial to preventing water penetration, thereby improving the waterproof performance of the photovoltaic system composed of a plurality of photovoltaic tiles. Through the first overlapping structure 421 and the second overlapping structure 422, the stable overlapping of two adjacent photovoltaic tiles of the same type along the first direction can be realized, and the opening direction of the first overlapping groove 4211 in the first overlapping structure 421 is opposite to the opening direction of the second overlapping groove 4221 in the second overlapping structure 422, which is beneficial to forming a waterproof overlap.

[0078] In a preferred embodiment of the present utility model, the photovoltaic tile is divided into a first photovoltaic tile 1 and a second photovoltaic tile 2. Referring to Figure 2 In Figure 4, the second side lapping structure in the second photovoltaic tile 2 is the sixth lapping structure 426; the fifth lapping structure 425 has a fifth lapping groove 4251 with an upward opening, and the sixth lapping structure 426 has a sixth lapping groove 4261 with a downward opening. The fifth lapping structure 425 matches the sixth lapping structure 426. The two sixth lapping structures 426 in the second photovoltaic tile 2 are respectively used to lap with the fifth lapping structures 425 in two adjacent first photovoltaic tiles 1.

[0079] Specifically, the first photovoltaic tile 1 is used to be fixed to the building structure, and the first photovoltaic tile 1 can be specifically fixed to the building structure through the second fastener 8. The second photovoltaic tile 2 is lapped between two first photovoltaic tiles 1. When two adjacent photovoltaic tiles of different types are lapped along the second direction, only need to buckle the sixth lapping structure 426 on the fifth lapping structure 425. The opening direction of the fifth lapping groove 4251 in the fifth lapping structure 425 is opposite to the opening direction of the sixth lapping groove 4261 in the sixth lapping structure 426, which is beneficial to prevent water penetration, thereby improving the waterproof performance of the photovoltaic system composed of multiple photovoltaic tiles. Through the fifth lapping structure 425 and the sixth lapping structure 426, the stable lapping of two adjacent photovoltaic tiles of different types along the second direction can be realized. In addition, the opening direction of the fifth lapping groove 4251 in the fifth lapping structure 425 is opposite to the opening direction of the sixth lapping groove 4261 in the sixth lapping structure 426, which is beneficial to form a waterproof lap. In addition, the photovoltaic tiles are lapped with adjacent photovoltaic tiles along both the first direction and the second direction. The multi-directional lapping structure design can provide stronger structural stability.

[0080] Refer to Figure 5 and Figure 6 , in a preferred embodiment of the present utility model, a seal 5 is covered on the second lapping structure 422. The seal 5 is used to be in close contact with the first lapping structure 421 in the adjacent photovoltaic tile. The material of the seal 5 can be silica gel. The seal 5 can be bonded to the second lapping structure 422. The seal 5 can fill the gap between the first lapping structure 421 and the second lapping structure 422, prevent water penetration, thereby improving the waterproof performance of the whole photovoltaic system.

[0081] Refer to Figure 5 and Figure 6, in a preferred embodiment of the present utility model, the first overlapping structure 421 includes a first base 4212, a first protruding portion 4213 and a second protruding portion 4214 provided on the first base 4212. The first overlapping groove 4211 includes a first groove portion 4215, a second groove portion 4216 and a third groove portion 4217. The first groove portion 4215 is located above the first protruding portion 4213, the second groove portion 4216 is located between the first protruding portion 4213 and the second protruding portion 4214, and the third groove portion 4217 is located on the side of the second protruding portion 4214 away from the first protruding portion 4213. The seal 5 includes a first matching portion 51, a second matching portion 52 and a third matching portion 53 respectively matching with the first groove portion 4215, the second groove portion 4216 and the third groove portion 4217. The first matching portion 51, the second matching portion 52 and the third matching portion 53 in the seal 5 are respectively used for buckling on the first groove portion 4215, the second groove portion 4216 and the third groove portion 4217 in the first overlapping structure 421 of adjacent photovoltaic tiles.

[0082] Specifically, a second cavity 45 may be formed in the first base 4212. The shape of the first protruding portion 4213 may be rectangular, and the shape of the second protruding portion 4214 may be triangular. The shape of the first groove portion 4215 may be rectangular, the shape of the second groove portion 4216 may be trapezoidal, and the shape of the third groove portion 4217 may be triangular. Correspondingly, the shape of the first matching portion 51 is rectangular, the shape of the second matching portion 52 is trapezoidal, and the shape of the third matching portion 53 is triangular. A water trace detection strip 7 is further provided on the top of the second protruding portion 4214, and the water trace detection strip 7 is located between the second protruding portion 4214 and the seal 5. The water trace detection strip 7 is generally used to detect whether it is wet or there is water leakage. The water trace detection strip 7 may be made of a water-absorbing material and will change color when contacting moisture. In the embodiment of the present utility model, through the arrangement of multiple groove portions and multiple matching portions, multiple seals can be realized to improve the sealing performance at the overlapping part and effectively prevent the intrusion of moisture and dust.
