[0002] Currently, photovoltaic modules can be used as building exteriors in scenarios such as shed roofs and house roofs. In such application scenarios, multiple installed photovoltaic modules as a whole need to have the ability to seal and prevent water leakage. In the prior art, two adjacent photovoltaic modules can form a labyrinth structure through the overlap of their respective frames, thereby having a certain ability to seal and prevent water leakage.

[0003] However, in the prior art, the frames of photovoltaic modules need to be designed with a relatively complex structure to be able to overlap and form a labyrinth structure, resulting in a larger size of the frames and a smaller effective installation area of the photovoltaic modules. That is to say, the installation area of the components (such as photovoltaic tiles) that can perform photovoltaic conversion in the photovoltaic modules is smaller. Moreover, the larger size of the frames will also affect the installation appearance, waste materials. And in the prior art, there is still a situation where the gaps at the overlap of the frames of two adjacent photovoltaic modules are not tightly sealed and leak water, making it difficult to meet the requirements of sealing and waterproofing.

[0046] To enable those skilled in the art to better understand the technical solutions of the present utility model, the sealing structure of the frame of the photovoltaic module, the frame of the photovoltaic module, and the photovoltaic module provided by the present utility model will be described in detail below with reference to the accompanying drawings.

[0047] As Figures 1-5 and Figures 7-9 shown, the embodiment of the present utility model provides a sealing structure for the frame 102 of a photovoltaic module, including a first sealing connector 1 and a second sealing connector 2. The first sealing connector 1 and the second sealing connector 2 are used to connect to the frames 102 of two adjacent photovoltaic modules 100 in a one-to-one correspondence. The first sealing connector 1 includes a first sealing portion 11, and the second sealing connector 2 includes a second sealing portion 21. The first sealing portion 11 and the second sealing portion 21 are elastic and can abut against each other, and can undergo elastic deformation when abutting against each other to seal the gap between the frames 102 of two adjacent photovoltaic modules 100, and at least one of the first sealing portion 11 and the second sealing portion 21 has a porous structure 3.

[0048] The sealing structure of the photovoltaic module frame 102 provided by the embodiment of the present utility model seals the gap between the frames 102 of two adjacent photovoltaic modules 100 by the relative abutment of the first sealing portion 11 and the second sealing portion 21 to cause elastic deformation. Thus, there is no need to design a more complex structure for the frames 102 of two adjacent photovoltaic modules 100 and form a labyrinth structure for sealing the gap between the frames 102 of two adjacent photovoltaic modules 100 by lapping. Subsequently, the size of the frame 102 can be reduced, and then the effective paving area of the photovoltaic module 100 can be increased, the paving appearance can be improved, materials can be saved. And by making at least one of the first sealing portion 11 and the second sealing portion 21 have a porous structure 3, since the first sealing portion 11 and / or the second sealing portion 21 having the porous structure 3 is softer and has stronger resilience, when the first sealing portion 11 and the second sealing portion 21 are relatively abutted, at least one of the first sealing portion 11 and the second sealing portion 21 having the porous structure 3 can be more closely squeezed and fitted with the other, so that the sealing and waterproofing ability can be improved, and there is no need to use a sealant 103 for further sealing, and then the paving can be made simpler.

[0049] Such as Figures 1-5 And Figures 7-9As shown, in the first embodiment, the second embodiment and the third embodiment of the present utility model, the first sealing portion 11 has a porous structure 3 (that is, a plurality of holes are distributed at intervals in the first sealing portion 11), and the second sealing portion 21 does not have a porous structure 3. The first sealing connector 1 is connected to the frame 102 of one of the two adjacent photovoltaic modules 100, and the second sealing connector 2 is connected to the frame 102 of the other photovoltaic module 100 among the two adjacent photovoltaic modules 100. Since the first sealing portion 11 and the second sealing portion 21 are elastic, when the first sealing portion 11 and the second sealing portion 21 are in relative abutment, the first sealing portion 11 and the second sealing portion 21 will undergo elastic deformation due to relative extrusion, so that the first sealing portion 11 and the second sealing portion 21 can be closely attached, thereby being able to seal the gap between the frames 102 of the two adjacent photovoltaic modules 100. Subsequently, it is not necessary to design a more complex structure for the frames 102 of the two adjacent photovoltaic modules 100 and form a labyrinth structure for sealing the gap between the frames 102 of the two adjacent photovoltaic modules 100 by overlapping. Subsequently, the size of the frame 102 can be reduced, and thus the effective paving area of the photovoltaic module 100 can be increased, the paving appearance can be improved, and materials can be saved. Since the first sealing portion 11 has a porous structure 3 and the second sealing portion 21 does not have a porous structure 3, the first sealing portion 11 is softer and has a stronger resilience ability than the second sealing portion 21. Therefore, when the first sealing portion 11 and the second sealing portion 21 are in relative abutment, the first sealing portion 11 can be more closely pressed and attached to the second sealing portion 21, thereby being able to improve the sealing and waterproof ability, and it is not necessary to use a sealant 103 for further sealing, and thus the paving can be made simpler.

[0050] However, in the embodiments of the present utility model, the case where the first sealing portion 11 and the second sealing portion 21 have a porous structure 3 is not limited thereto. For example, it may also be that both the first sealing portion 11 and the second sealing portion 21 have a porous structure 3, or it may also be that the first sealing portion 11 does not have a porous structure 3 and the second sealing portion 21 has a porous structure 3.

[0051] Such as Figure 1 , Figure 2 and Figure 7 As shown, optionally, when the first sealing connector 1 and the second sealing connector 2 are respectively connected to the frames 102 of the two adjacent photovoltaic modules 100 in a one-to-one correspondence, the first sealing portion 11 and the second sealing portion 21 may be located between the frames 102 of the two adjacent photovoltaic modules 100 and be oppositely arranged.

[0052] Such as Figures 1-5 and Figures 7-9As shown, in the first embodiment, the second embodiment and the third embodiment of the present utility model, the first sealing connector 1 may further include a first connecting portion 12, and the second sealing connector 2 may further include a second connecting portion 22. The first sealing portion 11 is connected to the frame 102 of the corresponding photovoltaic module 100 through the first connecting portion 12, and the first sealing portion 11 is connected to the frame 102 of the corresponding photovoltaic module 100 through the second connecting portion 22.

[0053] As Figure 1 , Figure 2 , Figure 7 and Figure 11 shown, in practical applications, the frame 102 of the photovoltaic module 100 may be provided with a slot 1021. At least a part of the first connecting portion 12 may be inserted into the slot 1021, so as to realize the connection between the first connecting portion 12 and the frame 102 of the photovoltaic module 100. At least a part of the second connecting portion 22 may be inserted into the slot 1021, so as to realize the connection between the second connecting portion 22 and the frame 102 of the photovoltaic module 100.

[0054] Optionally, the first sealing portion 11 and the first connecting portion 12 may be an integral structure.

[0055] Optionally, the second sealing portion 21 and the second connecting portion 22 may be an integral structure.

[0056] Optionally, the first connecting portion 12 may be elastic.

[0057] Optionally, the second connecting portion 22 may be elastic.

[0058] In the embodiments of the present utility model, a cavity 4 may be provided between the first sealing portion 11 and the first connecting portion 12, and / or a cavity 4 may be provided between the second sealing portion 21 and the second connecting portion 22.

[0059] Such a design is because when the first sealing portion 11 and the second sealing portion 21 are in relative abutment, the first sealing portion 11 will elastically deform in the direction close to the first connecting portion 12, and the second sealing portion 21 will elastically deform in the direction close to the second connecting portion 22. As Figures 1-3 and Figure 7 and Figure 6 shown, in the first embodiment, the second embodiment and the third embodiment of the present utility model, by providing a cavity 4 between the first sealing portion 11 and the first connecting portion 12, the first sealing portion 11 can have a larger deformation space to approach the first connecting portion 12, so as to reduce the interference of the first connecting portion 12 on the deformation of the first sealing portion 11, enable the first sealing portion 11 to deform more fully, and thus further improve the sealing ability. As Figure 1 , Figure 2 , Figure 4 , Figure 5, Figure 7 and Figure 9 As shown in Figure 7 and Figure 9 , in the first, second, and third embodiments of the present utility model, by providing a cavity 4 between the second sealing portion 21 and the second connecting portion 22, the second sealing portion 21 can have a greater deformation space to approach the second connecting portion 22, thereby reducing the interference of the second connecting portion 22 on the deformation of the second sealing portion 21, enabling the second sealing portion 21 to deform more fully, and further improving the sealing ability.

[0060] Optionally, the first sealing portion 11 may be arc-shaped, and / or the second sealing portion 21 may be arc-shaped.

[0061] As Figures 1-3 shown, in the first and second embodiments of the present utility model, by making the first sealing portion 11 arc-shaped, not only can a cavity 4 be formed between the first sealing portion 11 and the first connecting portion 12, but also the first sealing portion 11 can more easily undergo elastic deformation, thereby further improving the sealing ability. As Figure 1 , Figure 2 , Figure 4 and 5 shown, in the first and second embodiments of the present utility model, by making the second sealing portion 21 arc-shaped, not only can a cavity 4 be formed between the second sealing portion 21 and the second connecting portion 22, but also the second sealing portion 21 can more easily undergo elastic deformation, thereby further improving the sealing ability.

[0062] In the embodiments of the present utility model, one end of the first sealing portion 11 may be connected to the first connecting portion 12, and the other end may be separated from the first connecting portion 12 to make the cavity 4 have an opening 41, and / or one end of the second sealing portion 21 may be connected to the second connecting portion 22, and the other end may be separated from the second connecting portion 22 to make the cavity 4 have an opening 41.

[0063] As Figure 1 , Figure 2 , Figure 4 and 5 shown, in the first and second embodiments of the present utility model, one end of the second sealing portion 21 is connected to the second connecting portion 22, and the other end is separated from the second connecting portion 22. The cavity 4 between the second sealing portion 21 and the second connecting portion 22 has an opening 41. By making one end of the second sealing portion 21 connected to the second connecting portion 22 and the other end separated from the second connecting portion 22 to make the cavity 4 have an opening 41, the second sealing portion 21 can more easily undergo elastic deformation, thereby further improving the sealing ability.

[0064] As Figure 1 and Figure 4As shown, in the first embodiment of the present utility model, the opening 41 of the cavity 4 can face the tops of the first sealing portion 11 and the second sealing portion 21.

[0065] Such a design enables the liquid accumulated at the tops of the first sealing portion 11 and the second sealing portion 21 to enter the cavity 4 through the opening 41 of the cavity 4. In practical applications, the frame 102 connected by the first sealing connector 1 and / or the second sealing connector 2 having the cavity 4 with the opening 41 can be arranged along the direction of the roof shed, so that at both ends of the cavity 4 there is a height difference in the roof slope direction, that is to say, in the roof slope direction, the cavity 4 is inclined, so that the liquid entering the cavity 4 through the opening 41 of the cavity 4 can be discharged to the outside through the inclined cavity 4. That is to say, by making the cavity 4 with the opening 41 form a structure similar to an inclined liquid drainage channel, the liquid drainage function is realized by means of the cavity 4 with the opening 41, and then it can be avoided that the liquid accumulated at the tops of the first sealing portion 11 and the second sealing portion 21 flows to the bottoms of the first sealing portion 11 and the second sealing portion 21 through the gap between the first sealing portion 11 and the second sealing portion 21, and further the sealing ability can be improved.

[0066] However, the orientation of the opening 41 of the cavity 4 is not limited to this. For example, as Figure 2 and Figure 5 shown, in the second embodiment of the present utility model, the opening 41 of the cavity 4 can face the bottoms of the first sealing portion 11 and the second sealing portion 21.

[0067] As Figure 1 and Figure 4 shown, optionally, the bottom end of the second sealing portion 21 is connected to the second connecting portion 22, and the top end is separated from the second connecting portion 22, so that the opening 41 of the cavity 4 can face the tops of the first sealing portion 11 and the second sealing portion 21.

[0068] As Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 7 and Figure 9 shown, in the first, second and third embodiments of the present utility model, the second sealing connector 2 can further include a water shedding portion 5. The water shedding portion 5 is connected to the second connecting portion 22 and covers the tops of the first sealing portion 11 and the second sealing portion 21, and is used to cover the tops of the frames 102 of two adjacent photovoltaic modules 100 respectively.

[0069] By covering the water-repellent part 5 on the tops of the first sealing part 11 and the second sealing part 21, and covering the water-repellent part 5 on the tops of the frames 102 of two adjacent photovoltaic modules 100, the water-repellent part 5 can be used to block and divert the liquid, and divert the liquid to the photovoltaic body 101 of the photovoltaic module 100, avoiding the liquid flowing to the tops of the first sealing part 11 and the second sealing part 21. Thus, it can be avoided that the liquid flows downward through the gap between the first sealing part 11 and the second sealing part 21, and further, the sealing ability can be improved.

[0070] As Figure 1 and Figure 4 shown, in the first embodiment of the present utility model, the connection part between the second sealing part 21 and the second connecting part 22 is located below the connection part between the water-repellent part 5 and the second connecting part 22, and the opening 41 of the cavity 4 faces the water-repellent part 5, for discharging the liquid flowing to the lower part of the water-repellent part 5 to the outside.

[0071] Such a design can, on the one hand, make the connection between the second sealing part 21 and the second connecting part 22 staggered from the connection part between the water-repellent part 5 and the second connecting part 22, thus facilitating the mold opening and processing of the second sealing connecting piece 2. On the other hand, it can make the opening 41 of the cavity 4 face the water-repellent part 5, so that the liquid flowing through the gap between the water-repellent part 5 and the top of the frame 102 to the tops of the first sealing part 11 and the second sealing part 21 can enter the cavity 4 through the opening 41 of the cavity 4, and thus can be discharged to the outside through the cavity 4, avoiding the liquid flowing to the tops of the first sealing part 11 and the second sealing part 21 from accumulating on the tops of the first sealing part 11 and the second sealing part 21. Thus, it can be avoided that the liquid flowing to the tops of the first sealing part 11 and the second sealing part 21 flows downward between the first sealing part 11 and the second sealing part 21 due to accumulation on the tops of the first sealing part 11 and the second sealing part 21, and further, the sealing ability can be improved.

[0072] As Figure 1 、 Figure 2 、 Figure 4 and Figure 5 shown, in the first and second embodiments of the present utility model, the water-repellent part 5 has elasticity and can be in mutual abutment with the tops of the frames 102 of two adjacent photovoltaic modules 100, and can undergo elastic deformation when in mutual abutment with the tops of the frames 102 of two adjacent photovoltaic modules 100, so as to fit on the tops of the frames 102 of two adjacent photovoltaic modules 100.

[0073] By making the water-repellent part 5 elastic, the water-repellent part 5 can undergo elastic deformation when it abuts against the tops of the frames 102 of two adjacent photovoltaic modules 100, enabling the water-repellent part 5 to closely fit against the tops of the frames 102 of two adjacent photovoltaic modules 100, thereby reducing the liquid passing through the gap between the water-repellent part 5 and the tops of the frames 102, and further improving the sealing ability.

[0074] As Figure 1 , Figure 2 , Figure 4 and Figure 5 shown, in the first and second embodiments of the present utility model, before the second sealing connector 2 is connected to the frame 102, the water-repellent part 5 can have a certain curvature, so that after the second sealing connector 2 is connected to the frame 102, the water-repellent part 5 can abut against the tops of the frames 102 of two adjacent photovoltaic modules 100, and can undergo elastic deformation when abutting against the tops of the frames 102 of two adjacent photovoltaic modules 100.

[0075] As Figure 7 and Figure 8 shown, in the third embodiment of the present utility model, the first sealing connector 1 can further include a blocking part 6. The blocking part 6 is connected to the first connecting part 12 and is located between the first connecting part 12 and the water-repellent part 5, and is used to block the liquid from flowing into the gap between the first sealing part 11 and the second sealing part 21.

[0076] In practical applications, with the help of the blocking part 6, the liquid flowing through the gap between the water-repellent part 5 and the top of the frame 102 to the tops of the first sealing part 11 and the second sealing part 21 can be blocked, thereby blocking the liquid from flowing into the gap between the first sealing part 11 and the second sealing part 21, and further improving the sealing ability.

[0077] In the first, second, and third embodiments of the present utility model, the sealing structure can further include a diversion component 7. The diversion component 7 is respectively connected to the frames 102 of two adjacent photovoltaic modules 100 and is arranged below the first sealing part 11 and the second sealing part 21, and is used to discharge the liquid flowing to the lower parts of the first sealing part 11 and the second sealing part 21 to the outside.

[0078] By arranging the diversion component 7 below the first sealing part 11 and the second sealing part 21, the liquid flowing through the gap between the first sealing part 11 and the second sealing part 21 to the lower parts of the first sealing part 11 and the second sealing part 21 can be discharged to the outside by means of the diversion component 7, preventing the liquid flowing to the lower parts of the first sealing part 11 and the second sealing part 21 from continuing to flow downward, and further improving the sealing ability.

[0079] As Figure 1 , Figure 2and Figures 4-6 As shown, in the first and second embodiments of the present utility model, the diversion component 7 may include a third sealing connector 71 and a fourth sealing connector 72. The third sealing connector 71 and the fourth sealing connector 72 are used to connect to the frames 102 of two adjacent photovoltaic modules 100 in a one-to-one correspondence. The third sealing connector 71 includes a third sealing portion 711, and the fourth sealing connector 72 includes a fourth sealing portion 721. The third sealing portion 711 and the fourth sealing portion 721 are elastic and can abut against each other, and can undergo elastic deformation when abutting against each other to seal the gap between the frames 102 of two adjacent photovoltaic modules 100. And at least one of the third sealing portion 711 and the fourth sealing portion 721 has a diversion structure, and the diversion structure is used to discharge the liquid flowing to the lower part of the first sealing portion 11 and the second sealing portion 21.

[0080] For example, as Figure 1 , Figure 2 and Figures 4-6 shown, in the first and second embodiments of the present utility model, the third sealing portion 711 does not have a diversion structure, and the fourth sealing portion 721 has a diversion structure. The third sealing connector 71 is connected to the frame 102 of one of the two adjacent photovoltaic modules 100, and the fourth sealing connector 72 is connected to the frame 102 of the other of the two adjacent photovoltaic modules 100. Since the third sealing portion 711 and the fourth sealing portion 721 are elastic, when the third sealing portion 711 and the fourth sealing portion 721 abut against each other, the third sealing portion 711 and the fourth sealing portion 721 will undergo elastic deformation due to relative extrusion, so that the third sealing portion 711 and the fourth sealing portion 721 can be closely attached, thereby being able to seal the gap between the frames 102 of two adjacent photovoltaic modules 100. In this way, the third sealing portion 711 and the fourth sealing portion 721 can block the liquid flowing to the lower part of the first sealing portion 11 and the second sealing portion 21, and thus the liquid flowing to the lower part of the first sealing portion 11 and the second sealing portion 21 can be discharged to the outside through the diversion structure, avoiding the liquid flowing to the lower part of the first sealing portion 11 and the second sealing portion 21 from continuing to flow downward through the gap between the third sealing portion 711 and the fourth sealing portion 721.

[0081] Moreover, the gap between the frames 102 of two adjacent photovoltaic modules 100 is sealed by the elastic first sealing portion 11 and the second sealing portion 21 abutting against each other and undergoing elastic deformation, so that there is no need to design a more complex structure for the frames 102 of two adjacent photovoltaic modules 100 and form a labyrinth structure for sealing the gap between the frames 102 of two adjacent photovoltaic modules 100 by overlapping. Subsequently, the size of the frame 102 can be reduced, and then the effective paving area of the photovoltaic module 100 can be increased, the paving appearance can be improved, and materials can be saved.

[0082] However, in the embodiments of the present utility model, the case where the third sealing portion 711 and the fourth sealing portion 721 have a diversion structure is not limited thereto. For example, it may also be that both the third sealing portion 711 and the fourth sealing portion 721 have a diversion structure, or it may be that the third sealing portion 711 has a diversion structure and the fourth sealing portion 721 does not have a diversion structure.

[0083] In the embodiments of the present utility model, at least one of the third sealing portion 711 and the fourth sealing portion 721 may have a porous structure 3.

[0084] By making at least one of the third sealing portion 711 and the fourth sealing portion 721 have a porous structure 3, since the third sealing portion 711 and / or the fourth sealing portion 721 having the porous structure 3 is softer and has a stronger resilience ability, when the third sealing portion 711 and the fourth sealing portion 721 are in relative abutment, at least one of the third sealing portion 711 and the fourth sealing portion 721 having the porous structure 3 can be more closely pressed and fitted with the other, thereby improving the sealing and waterproof ability, without the need to use a sealant 103 for further sealing, and thus making the paving simpler.

[0085] For example, as Figure 1 , Figure 2 and Figures 4-6 shown, in the first and second embodiments of the present utility model, the third sealing portion 711 has a porous structure 3 and the fourth sealing portion 721 does not have a porous structure 3. Since the third sealing portion 711 has a porous structure 3 and the fourth sealing portion 721 does not have a porous structure 3, the third sealing portion 711 is softer and has a stronger resilience ability than the fourth sealing portion 721. Therefore, when the third sealing portion 711 and the fourth sealing portion 721 are in relative abutment, the third sealing portion 711 can be more closely pressed and fitted with the fourth sealing portion 721, thereby improving the sealing and waterproof ability, without the need to use a sealant 103 for further sealing, and thus making the paving simpler.

[0086] However, in the embodiments of the present utility model, the case where the third sealing portion 711 and the fourth sealing portion 721 have a porous structure 3 is not limited thereto. For example, it may also be that both the third sealing portion 711 and the fourth sealing portion 721 have a porous structure 3, or it may be that the third sealing portion 711 does not have a porous structure 3 and the fourth sealing portion 721 has a porous structure 3.

[0087] Such as Figure 1 , Figure 2 and Figures 4-6As shown, in the first and second embodiments of the present utility model, the third sealing connector 71 may further include a third connecting portion 712, and the fourth sealing connector 72 may further include a fourth connecting portion 722. The third sealing portion 711 is connected to the frame 102 of the corresponding photovoltaic module 100 through the third connecting portion 712, and the fourth sealing portion 721 is connected to the frame 102 of the corresponding photovoltaic module 100 through the fourth connecting portion 722.

[0088] As Figure 1 , Figure 2 , Figure 7 and Figure 11 shown, in practical applications, the frame 102 of the photovoltaic module 100 may be provided with a slot 1021. At least a part of the third connecting portion 712 may be inserted into the slot 1021, so as to realize the connection between the third connecting portion 712 and the frame 102 of the photovoltaic module 100. At least a part of the fourth connecting portion 722 may be inserted into the slot 1021, so as to realize the connection between the fourth connecting portion 722 and the frame 102 of the photovoltaic module 100.

[0089] Optionally, the third sealing portion 711 and the third connecting portion 712 may be of an integral structure.

[0090] Optionally, the fourth sealing portion 721 and the fourth connecting portion 722 may be of an integral structure.

[0091] Optionally, the third connecting portion 712 may have elasticity.

[0092] Optionally, the fourth connecting portion 722 may have elasticity.

[0093] In the embodiment of the present utility model, one end of the third sealing portion 711 is connected to the third connecting portion 712, and the other end is separated from the third connecting portion 712, so as to form a cavity 4 with an opening 41 facing the first sealing portion 11 and the second sealing portion 21 between the third sealing portion 711 and the third connecting portion 712, and / or one end of the fourth sealing portion 721 is connected to the fourth connecting portion 722, and the other end is separated from the fourth connecting portion 722, so as to form a cavity 4 with an opening 41 facing the first sealing portion 11 and the second sealing portion 21 between the fourth sealing portion 721 and the fourth connecting portion 722. The cavity 4 with an opening 41 facing the first sealing portion 11 and the second sealing portion 21 serves as a diversion structure.

[0094] For example, as Figure 1 , Figure 2 and Figures 4-6As shown, in the first and second embodiments of the present utility model, a cavity 4 without an opening 41 facing the first sealing portion 11 and the second sealing portion 21 is formed between the third sealing portion 711 and the third connecting portion 712, and a cavity 4 with an opening 41 facing the first sealing portion 11 and the second sealing portion 21 is formed between the fourth sealing portion 721 and the fourth connecting portion 722. When the liquid flows through the gap between the first sealing portion 11 and the second sealing portion 21 to the lower part of the first sealing portion 11 and the second sealing portion 21, it can enter the cavity 4 through the opening 41 facing the first sealing portion 11 and the second sealing portion 21, and thus can be discharged to the outside through the cavity 4, avoiding the liquid flowing to the lower part of the first sealing portion 11 and the second sealing portion 21 from continuing to flow downward through the gap between the third sealing portion 711 and the fourth sealing portion 721, and further improving the sealing ability.

[0095] Optionally, the third connecting portion 712 and the first connecting portion 12 may be of an integral structure, and / or the fourth connecting portion 722 and the second connecting portion 22 may be of an integral structure.

[0096] For example, as Figure 1 、 Figure 2 and Figures 4-6 shown, in the first and second embodiments of the present utility model, the third connecting portion 712 and the first connecting portion 12 are of a split structure, that is to say, the third sealing connecting member 71 and the first sealing connecting member 1 are of a split structure, and the fourth connecting portion 722 and the second connecting portion 22 are of an integral structure, that is to say, the fourth sealing connecting member 72 and the second sealing connecting member 2 are of an integral structure.

[0097] Such as Figure 7 and Figure 10 shown, in the third embodiment of the present utility model, the guiding member 7 may include a guiding connecting portion 73 and a guiding portion 74. The guiding connecting portion 73 is respectively connected to the frames 102 of two adjacent photovoltaic modules 100, and the guiding portion 74 is integrally connected to the guiding connecting portion 73 and is arranged below the first sealing portion 11 and the second sealing portion 21. The guiding portion 74 is used to discharge the liquid flowing to the lower part of the first sealing portion 11 and the second sealing portion 21 to the outside.

[0098] In practical applications, since the guiding connecting portion 73 is respectively connected to the frames 102 of two adjacent photovoltaic modules 100, and the guiding portion 74 is integrally connected to the guiding connecting portion 73, the guiding portion 74 can block the liquid flowing to the lower part of the first sealing portion 11 and the second sealing portion 21 and discharge the liquid flowing to the lower part of the first sealing portion 11 and the second sealing portion 21 to the outside, thereby avoiding the liquid flowing to the lower part of the first sealing portion 11 and the second sealing portion 21 from continuing to flow downward.

[0099] Such as Figure 7 and Figure 10As shown, in the third embodiment of the present utility model, the diversion part 74 may have a diversion groove 75 for discharging the liquid flowing to the lower sides of the first sealing part 11 and the second sealing part 21.

[0100] In practical applications, the diversion groove 75 may be arranged along the direction of the roof shed, so that there may be a height difference between the two ends of the diversion groove 75 in the roof slope direction. That is to say, in the roof slope direction, the diversion groove 75 may be inclined. In this way, the liquid flowing through the gap between the first sealing part 11 and the second sealing part 21 to the lower side of the diversion groove 75 of the first sealing part 11 and the second sealing part 21 can be discharged to the outside through the inclined diversion groove 75, realizing the liquid drainage function of the diversion groove 75.

[0101] Optionally, the frames 102 of two adjacent photovoltaic modules 100 respectively connected to the diversion connection part 73 and the diversion part 74 may be arranged along the direction of the roof shed, so that the diversion connection part 73 can be arranged along the direction of the roof shed, then the diversion part 74 can be arranged along the direction of the roof shed, and further the diversion groove 75 can be arranged along the direction of the roof shed.

[0102] In the embodiment of the present utility model, the first sealing connector 1 may further include a drainage part 8, which is connected to the bottom of the first sealing part 11 and extends into the diversion groove 75 for draining the liquid flowing to the bottom of the first sealing part 11 into the diversion groove 75; and / or, the second sealing connector 2 may further include a drainage part 8, which is connected to the bottom of the second sealing part 21 and extends into the diversion groove 75 for draining the liquid flowing to the bottom of the second sealing part 21 into the diversion groove 75.

[0103] For example, as Figures 7-10As shown in the figure, in the third embodiment of the present utility model, both the first sealing connector 1 and the second sealing connector 2 include a drainage portion 8. The bottom of the first sealing portion 11 and the bottom of the second sealing portion 21 are both connected to the drainage portion 8. In practical applications, the drainage portion 8 at the bottom of the first sealing portion 11 can drain the liquid flowing to the bottom of the first sealing portion 11 into the diversion groove 75, and the drainage portion 8 at the bottom of the second sealing portion 21 can drain the liquid flowing to the bottom of the second sealing portion 21 into the diversion groove 75. Thus, the liquid flowing to the bottom of the first sealing portion 11 and the liquid flowing to the bottom of the second sealing portion 21 can be centrally drained into the diversion groove 75, preventing the liquid flowing to the bottom of the first sealing portion 11 and the liquid flowing to the bottom of the second sealing portion 21 from flowing downward and spreading out. This enables the liquid flowing to the bottom of the first sealing portion 11 and the liquid flowing to the bottom of the second sealing portion 21 to flow centrally into the diversion groove 75, allowing the diversion groove 75 to centrally discharge the liquid flowing below the first sealing portion 11 and the second sealing portion 21 to the outside, preventing the liquid flowing below the first sealing portion 11 and the second sealing portion 21 from continuing to flow downward from other positions, and further improving the sealing ability.

[0104] As Figure 1 , Figure 2 , Figure 7 and Figure 11 shown, the present utility model embodiment also provides a frame 102 of a photovoltaic module 100. The frame 102 is used to be connected to the edge of the photovoltaic body 101 of the photovoltaic module 100 and the sealing structure provided by the present utility model embodiment respectively.

Thus, the size of the frame 102 can be reduced, and further, the effective paving area of the photovoltaic module 100 can be increased, the paving appearance can be improved, materials can be saved, and the sealing and waterproof ability can be enhanced. Moreover, the paving can be made simpler.

[0106] As Figure 1 , Figure 2 and Figure 7 shown, the present utility model embodiment also provides a photovoltaic module 100, which includes a photovoltaic body 101, a frame 102, and the sealing structure provided by the present utility model embodiment. The sealing structure is connected to the photovoltaic body 101 through the frame 102.

[0107] The photovoltaic module 100 provided by the embodiment of the present utility model connects the sealing structure of the photovoltaic module frame 102 provided by the embodiment of the present utility model to the photovoltaic body 101 through the frame 102. The sealing structure of the photovoltaic module frame 102 provided by the embodiment of the present utility model can be used to seal the gap between the frames 102 of two adjacent photovoltaic modules 100, so as to reduce the size of the frame 102, and further increase the effective paving area of the photovoltaic module 100, improve the paving appearance, save materials, and improve the sealing and waterproof ability, and further make the paving simple.

[0108] As Figure 1 , Figure 2 , Figure 7 and Figure 11 shown, optionally, a sealant 103 is provided between the frame 102 and the photovoltaic body 101, and the sealant 103 is used to seal the gap between the frame 102 and the photovoltaic body 101.

[0109] In summary, the sealing structure of the photovoltaic module frame 102, the frame 102 of the photovoltaic module 100, and the photovoltaic module 100 provided by the embodiment of the present utility model can reduce the size of the frame 102, so as to increase the effective paving area of the photovoltaic module 100, improve the paving appearance, save materials, and improve the sealing and waterproof ability, so as to make the paving simple.
