[0065] Reference Figures 1 to 5 The present application first provides a photovoltaic roof system 2000, including a plurality of photovoltaic components 1000, wherein the photovoltaic components 1000 are independent single structures, and the photovoltaic roof system 2000 is formed by moving the plurality of photovoltaic components 1000 to a construction site and connecting the plurality of photovoltaic components 1000 at the construction site.

[0066] The photovoltaic component 1000 includes a mounting structure 100 , a photovoltaic module 200 and a roof panel 300 . Along the extension direction of the roof panel 300 , the photovoltaic module 200 is connected to the roof panel 300 through the mounting structure 100 .

[0067] Specifically, the photovoltaic module 200 is usually composed of a plurality of photovoltaic cells to convert sunlight into electrical energy; its light-receiving surface faces the outside, and its backlight surface faces the roof panel 300, and may include stacked photovoltaic tempered glass, EVA film or POE film, photovoltaic cell strings, and photovoltaic backplane or photovoltaic backplane glass, etc., for photovoltaic power generation. Of course, the photovoltaic module 200 may also be composed of other structures, and the present application does not specifically limit the specific structure of the photovoltaic module 200.

[0068] The roof panel 300 is used as a structural support for installing the photovoltaic module 200, serving as a connection piece between the photovoltaic module 200 and the building structure and protecting the building structure. It can be connected to the roof, wall or other constructible outer wall.

[0069] Furthermore, along the extension direction of the roof panel 300 , the photovoltaic assembly 200 may be a single one, or a plurality of photovoltaic assemblies 200 may be sequentially arranged on the roof panel 300 along the extension direction.

[0070] When there are multiple photovoltaic modules 200 , the mounting structure 100 can leave gaps between the photovoltaic modules 200 mounted thereon so that installers can more easily perform wiring harness operations, and the gaps can serve as heat dissipation channels to help dissipate heat from the photovoltaic modules 200 .

[0071] The mounting structures 100 are arranged in pairs, and each pair of mounting structures 100 includes a component frame 10 and a photovoltaic support 20 that match each other, wherein the component frame 10 is connected to both sides of the photovoltaic component 200 along the second direction W. Similarly, the photovoltaic support 20 is connected to both sides of the roof panel 300. The photovoltaic component 200 is connected to the roof panel 300 by plugging the component frame 10 into the photovoltaic support 20.

[0072] It should be noted that the first direction L mentioned in the context of this application refers to the extension direction of the component frame 10, which can be referred to as Figure 2, when the component frame 10 is arranged at the two long sides of the photovoltaic component 200, that is, at this time, the first direction L can refer to the length direction of the photovoltaic component 200, and the component frame 10 is installed along the extension direction, while the second direction W and the third direction H refer to the two directions that are horizontally perpendicular and vertically perpendicular to the extension direction respectively; those skilled in the art should understand that the orientation or position relationship shown in the accompanying drawings is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. For example: if the component frame 10 is arranged at the two short sides of the photovoltaic component 200, at this time, the first direction L can also be understood as the width direction of the photovoltaic component 200.

[0073] like Figure 6 to Figure 7 The roof panel 300 includes a panel body 310 and an assembly portion 320 disposed at both ends of the panel body 310 in the second direction W. The panel body 310 includes at least one rib 330 protruding in the third direction H relative to the panel body 310, each rib 330 is disposed between two adjacent panel bodies 310 and connected to the two adjacent panel bodies 310, and the rib 330 can be used to contact the backlight surface of the photovoltaic module 200 to provide structural support for the photovoltaic module 200, disperse the load and strengthen the structural strength of the photovoltaic module 200, thereby improving the load bearing capacity of the photovoltaic module 200 and preventing the photovoltaic module 200 from deforming under stress.

[0074] Furthermore, guide grooves B are formed between two adjacent convex ribs 330 and between the convex ribs 330 and the plate body 310. Based on the diversion function of the guide grooves B, the accumulated water on the roof panel 300 can be discharged in time along the first direction L in rainy seasons.

[0075] Furthermore, a buffer gasket (not shown) is provided between the photovoltaic module 200 and the convex rib 330 to reduce the thermal stress caused by temperature changes and reduce the risk of damage to the photovoltaic module; at the same time, the buffer gasket can play a role in structural reinforcement and shock absorption for the photovoltaic module 200, reduce the influence of stress on the photovoltaic module 200, and thus improve the stability and safety of the photovoltaic module 200.

[0076] like Figure 7The assembly portion 320 includes an inclined mounting section 321 and a plane mounting section 322. The plane mounting section 322 is located on one side of the plate body 310 in the second direction W and is spaced apart from the plate body 310 in the third direction H. Specifically, the plane mounting section 322 is closer to the photovoltaic component 200 relative to the plate body 310. The inclined mounting section 321 is inclined relative to the plate body 310 to connect the plate body 310 and the plane mounting section 322. The plane mounting section 322 supports the mounting structure 100 in the third direction H. The mounting structure 100 is connected to the inclined mounting section 321. Through the inclined guiding effect of the inclined mounting section 321, rainwater can be prevented from being retained at the connection between the mounting structure 100 and the inclined mounting section 321 in rainy seasons, thereby reducing erosion of the mounting structure 100 and improving the reliability and durability of the connection between the support mounting structure 100 and the roof panel 300.

[0077] Furthermore, one end of the roof panel 300 is provided with a male locking edge 340a, and the other end is provided with a female locking edge 340b, wherein the male locking edge 340a and the female locking edge 340b are respectively provided on the side of the assembly portion 320 away from the plate body portion 310, and the adjacent roof panels 300 are overlapped and then screwed through the male locking edge 340a and the female locking edge 340b, so that the installer can quickly and accurately connect the roof panels together. This can save installation time and labor costs and improve construction efficiency. Moreover, the overlap structure of the male locking edge 340a and the female locking edge 340b can ensure that the roof panels are tightly connected.

[0078] like Figure 8 In another embodiment, the photovoltaic roof system 2000 includes the mounting structure 100 as described above, as well as a plurality of photovoltaic modules 200 and a roof panel 300 ; the plurality of photovoltaic modules 200 are connected to the roof panel 300 via the mounting structure 100 .

[0079] Reference Figures 9 and 10 Specifically, the component frame 10 includes a mounting portion 11 and an avoidance opening 12, wherein the avoidance opening 12 is disposed on the mounting portion 11, and the photovoltaic support 20 includes a plug-in portion 21. The avoidance opening 12 is configured to accommodate at least a portion of the photovoltaic support 20, so that the mounting portion 11 is plugged into the plug-in portion 21 via the avoidance opening 12.

[0080] In other words, during the installation process, it is necessary to first move the position of the component frame 10 so that the avoidance opening 12 on the mounting portion 11 can pre-accommodate at least a portion of the photovoltaic support 20, thereby limiting the installation position of the component frame 10, that is, at this time, the portion of the mounting portion 11 excluding the avoidance opening 12 can be located on one side of the photovoltaic support 20 in the first direction L, and then the component frame 10 can be directly pushed in the first direction L to plug the mounting portion 11 into the plug-in portion 21.

[0081] It is understandable that, due to the small clearance between the mounting portion 11 and the plug-in portion 21 when plugged in, there may be certain installation difficulties when directly aligning the mounting portion 11 with the plug-in portion 21, and the photovoltaic component 200 has a certain weight, and repeated alignment is time-consuming and laborious. An avoidance opening 12 is provided on the mounting portion 11, so that the mounting portion 11 can be pre-positioned before being plugged into the plug-in portion 21 based on the positioning function of the avoidance opening 12, so that the mounting portion 11 can be quickly plugged into the plug-in portion 21 after being positioned through the avoidance opening 12, so as to achieve the coordinated installation between the component frame 10 and the photovoltaic support 20, thereby saving time and effort during the entire installation process, and also improving the installation accuracy, avoiding unnecessary structural interference such as connection misalignment, skewness or excessive extrusion between the component frame 10 and the photovoltaic support 20. Furthermore, based on the plug-in connection between the mounting portion 11 and the plug-in portion 21 , there is no need to open a hole structure on the component frame 10 for mating with the photovoltaic support 20 , thereby avoiding the frame stress concentration problem caused by the opening and increasing the service life of the component frame 10 .

[0082] Furthermore, the component frame 10 further includes a frame connection portion 13, and the mounting portion 11 protrudes from the frame connection portion 13 in the second direction W and forms a mounting groove 14 together with the frame connection portion 13. At least a portion of the plug-in portion 21 is received in the mounting groove 14 to be plugged with the mounting portion 11.

[0083] Since the frame connection part 13 and the installation part 11 are arranged side by side in the second direction W, the frame connection part 13 will not block the avoidance opening 12 and the installation groove 14, so that the component frame 10 can be moved intuitively during the entire installation process so that the avoidance opening 12 can accommodate at least part of the photovoltaic support 20 and push the component frame 10 along the first direction L to plug the installation part 11 into the plug-in part 21, which further helps to quickly position and install, improves the installation efficiency, and at the same time, allows maintenance personnel to more easily know the status of the internal plug-in part 21, and quickly check whether the plug-in part 21 is loose, damaged or needs repair, etc., and disassembly is very convenient.

[0084] Furthermore, the frame connection portion 13 is provided with an installation cavity 15, and the photovoltaic component 200 is installed in the installation cavity 15. The installation cavity 15 is located on one side of the installation groove 14 in the second direction W, and the opening direction of the installation cavity 15 is set away from the installation portion 11 in the second direction W, while the opening direction of the installation groove 14 is set in the direction away from the photovoltaic support 20 in the third direction H. At this time, based on the relative position relationship between the installation cavity 15 and the installation groove 14, the installation process of the photovoltaic component 200 in the installation cavity 15 of the frame connection portion 13 and the process of plugging the component frame 10 into the photovoltaic support 20 do not affect each other, thereby helping to improve the installation efficiency.

[0085] Reference Fig. 9 and Fig.11 The mounting portion 11 and the plug-in portion 21 are connected by mutually nested and movable snap-fit ​​connections, and the mounting portion 11 and the plug-in portion 21 are mutually engaged in the second direction W; specifically, the mounting portion 11 includes a connecting section 111 and a blocking section 112. The blocking section 112 is spaced apart from the frame connecting portion 13 in the second direction W, and the connecting section 111 is connected to the blocking section 112 and the frame connecting portion 13 in the second direction W, so as to enclose the mounting groove 14 together with the blocking section 112 and the frame connecting portion 13.

[0086] When the mounting portion 11 is plugged into the plug-in portion 21, at least a portion of the plug-in portion 21 will be accommodated in the mounting groove 14, and the blocking section 112 of the mounting portion 11 will also extend into the plug-in portion 21. At this time, the mounting portion 11 and the plug-in portion 21 are mutually buckled and connected, and the mounting portion 11 can only slide relative to the plug-in portion 21 along the first direction L until it is installed in the corresponding position. During the sliding installation process, the blocking section 112 can cooperate with the plug-in portion 21, thereby further guiding the sliding process, thereby quickly plugging the mounting portion 11 into place.

[0087] Reference Fig.12 , the number of avoidance openings 12 can be one or more. When the number of avoidance openings 12 is multiple, the multiple avoidance openings 12 can divide the installation part 11 into multiple parts, each part can cooperate with a corresponding photovoltaic support 20 to install the photovoltaic module 200 on the roof panel 300. In other words, the installation part 11 can be set on both sides of an avoidance opening 12, so that the installer does not need to distinguish the positive and negative directions in the first direction L when installing the module frame 10. After the plug-in part 21 enters the avoidance opening 12, it can be plugged into the installation part 11 from both sides, thereby improving the fault tolerance, which can help simplify the installation process, improve the installation efficiency, and reduce the possibility of incorrect installation, avoiding the problem of reinstallation due to incorrect installation direction.

[0088] The avoidance opening 12 can also be called a notch or a notch structure, which can be formed by cutting the edge portion of the mounting portion 11 away from the frame connection portion 13. Specifically, the mounting portion 11 can be cut off as a whole in the second direction W so that the frame connection portion 13 can be exposed in the avoidance opening 12, and the mounting portion 11 is divided into multiple parts by the avoidance opening 12 and is equivalent to being arranged at intervals; of course, the mounting portion 11 can also be partially cut in the second direction W, and there is still an edge portion between the frame connection portion 13 and the avoidance opening 12, and the multiple parts of the mounting portion 11 divided by the avoidance opening 12 are equivalent to being connected by the edge portion.

[0089] Reference Fig.13The plug-in portion 21 includes a plug-in section 211, a first extension section 212, and a second extension section 213. Among them, at least a portion of the plug-in section 211 is accommodated in the mounting groove 14, and the mounting portion 11 can slide relative to the plug-in section 211 in the second direction W. At this time, it is equivalent to a clearance fit between the plug-in section 211 and the mounting groove 14, and the mounting groove 14 can provide a movable margin for the mounting portion 11 in the second direction W, thereby balancing the dimensional error during the installation process. Specifically, the plug-in section 211 can be formed into an L-shaped structure.

[0090] The second extension section 213 is located on the side of the mounting portion 11 away from the plug-in section 211 in the third direction H of the component frame 10, and the first extension section 212 is located on the side of the mounting portion 11 away from the frame connection portion 13 in the second direction W and is connected to the plug-in section 211 and the second extension section 213 in the third direction H. At this time, the second extension section 213 cooperates with the plug-in section 211 to limit the component frame 10 in the third direction H, so that the component frame 10 will not be separated from the photovoltaic support 20 in the third direction H during the installation process.

[0091] The plug-in section 211 can be configured to cooperate with the second extension section 213 to clamp the mounting portion 11 in the third direction H. At this time, based on the tight fit between the plug-in section 211, the second extension section 213 and the mounting portion 11, it is possible to limit the position of the component frame 10 in the third direction H without the need to provide other additional limiting members. During the sliding installation process, the component frame 10 needs to overcome the resistance of the plug-in section 211 and the second extension section 213 to the mounting portion 11 in order to smoothly slide along the first direction H and be installed in place.

[0092] Continue to refer to Fig.13 The photovoltaic support 20 also includes a support connecting part 22, the plug-in part 21 is connected to the support connecting part 22, the support connecting part 22 includes a matching section 221, a fixing pin 222 and a protective layer 223; the protective layer 223 is arranged between the matching section 221 and the roof panel 300, and the fixing pin 222 is passed through the matching section 221 and the roof panel 300 to connect the photovoltaic support 20 and the roof panel 300. Among them, the matching section 221 and the inclined mounting section 321 match each other to provide a stable mounting surface for connection. The fixing pin 222 passes through the matching section 221 and the roof panel 300, plays the role of connecting the support connecting part 22 and the roof panel 300, and provides a fastening force by locking to maintain a firm fixation between the two; the protective layer 223 is arranged between the matching section 221 and the roof panel 300, and is used to ensure that the contact area between the fixing pin 222 and the roof panel 300 is increased during the connection process, so as to prevent the surface of the roof panel 300 or the matching section 221 from being worn during the installation process. In addition, the protective layer 223 can play a certain role in preventing loosening.

[0093] Reference Fig.14The mounting structure 100 further includes at least one stopper 30, which is disposed on the mounting portion 11 or the plug-in portion 21 to limit the sliding movement of the plug-in portion 21 relative to the mounting portion 11 in the first direction L. The additional stopper 30 is used to limit the position, which will not affect the sliding installation process of the mounting portion 11 relative to the plug-in portion 21, thus saving time and effort, and enabling quick insertion into place.

[0094] It can be understood that when in use, the photovoltaic component 200 is usually tilted along the first direction L to better receive light, and the limit member 30 is arranged to stop the front end of the component frame 10 in the first direction L, so as to maintain a stable connection between the plug-in portion 21 and the mounting portion 11, thereby preventing the component frame 10 from accidentally sliding or falling off in the tilted direction under its own gravity or external force, thereby improving the reliability and stability of the connection.

[0095] Specifically, in order to facilitate sliding on the plug-in portion 21, at least one side of the mounting portion 11 close to the avoidance opening 12 may be provided with a guide surface A. The guide surface A may be an inclined structure.

[0096] In one embodiment, Fig.15 The mounting portion 11 and the plug-in portion 21 are both provided with a limiting through hole C. The limiting member 30 may be a pin, a top screw, a bolt or other stopper structure that can extend into the limiting through hole C. The limiting member 30 is at least partially passed through the limiting through hole of the mounting portion 11 and the limiting through hole C of the plug-in portion 21 to stop the plug-in portion 21 from sliding in the first direction L.

[0097] In an optional manner, the limit through hole C can be set along the third direction H or the limit through hole C can be set along the second direction W, which can be selected according to the adaptability of the processing surface; when the limit through hole C of the mounting part 11 is aligned with the limit through hole C of the plug-in part 21, it means that the plug-in is in place and the plug-in part 21 has reached the desired target position. At this time, inserting the limit member 30 into the limit through hole C can stop the mounting part 11 from sliding in the first direction L.

[0098] See also Fig.16In a variation based on the above, the plug-in portion 21 is provided with a limiting through hole C, and the mounting portion 11 is provided with a stop groove 16. The stop groove 16 can be understood as a notch provided in the mounting portion 11, i.e., a cut-off area. Among them, at least part of the limiter 30 is provided in the limiting through hole C, and the limiter 30 is provided to be able to extend into the stop groove 16 through the limiting through hole C to limit the sliding of the plug-in portion 21 in the first direction L. The limiter 30 can be movably connected to the limiting through hole C, for example: a pin passes through the limiting through hole C but is in clearance with the limiting through hole C, so as to be able to move freely in the third direction H. During the sliding process of the mounting portion 11 relative to the plug-in portion 21, when the mounting portion 11 slides to the position of the limiter 30, the limiter 30 will be lifted up first, and as the mounting portion 11 continues to move, until the limiter 30 is inserted into the stop groove 16 on the mounting portion 11.

[0099] Reference Figure 17 to Figure 18 In a preferred embodiment, the limiting member 30 is an elastic buckle, including a deformation portion 31 and a stop portion 32. The deformation portion 31 is connected to the plug-in portion 21 outside the mounting through hole 23, and the stop portion 32 is connected to the deformation portion 31. The stop portion 32 is configured to be able to penetrate the mounting through hole 23 and extend into the stop groove 16 to limit the sliding of the plug-in portion 21 in the first direction L. During the sliding process of the mounting portion 11 relative to the plug-in portion 21, when the mounting portion 11 slides to the position of the stop portion 32, the stop portion 32 will be lifted up first to deform the limiting member 30. As the mounting portion 11 continues to slide, until the stop portion 32 is inserted into the stop groove 16 on the mounting portion 11, the sliding of the plug-in portion 21 in the first direction L is limited.

[0100] Specific combination Fig.17 and Fig.18 See also Fig.19 (a~c), when the plug-in part 21 enters the avoidance opening 12, it moves in the direction of the mounting part 11. At this time, the stop part 32 arrives at the guide surface A of the mounting part 11 in advance, and the guide surface A squeezes the stop part 32 along its inclined direction. Under the action of the deformation part 31, the stop part 32 withdraws from the mounting through hole 23 and moves along the surface of the mounting part 11. When the stop part 32 arrives at the stop groove 16, the stop groove 16 extends into the stop groove 16 under the action of the rebound force of the deformation part 31 to limit the freedom of the plug-in part 21 in the first direction L.

[0101] In summary, the present application provides a mounting structure 100, wherein the component frame 10 and the photovoltaic support 20 are implemented by plugging through the mounting portion 11 and the plug-in portion 21, thereby simplifying the installation process. The installer only needs to insert the component frame 10 into the photovoltaic support 20 to complete the assembly. This simple operation can greatly improve the installation efficiency. Compared with the traditional bolt connection or welding embodiment, plug-in is more convenient and quick, reducing the installation time and labor cost. In addition, the present application sets an avoidance opening 12 at the mounting portion 11, and the plug-in portion 21 can be plugged into the mounting portion 11 through the avoidance opening 12, so that the mounting portion 11 of the component frame 10 and the photovoltaic support 20 can be more easily aligned with the plug-in portion 21 during the installation process. In addition, the design of the avoidance opening 12 requires simple processing, low precision requirements, and can reduce processing materials to save costs, while also taking into account lightweight.
