[0068] Reference Figure 1 The mounting structure 100 of the photovoltaic component 200 provided in the embodiment of the present application includes two component frames 10 and a support 20. The mounting structure 100 is used to install the photovoltaic component 200, wherein the photovoltaic component 200 is a panel that directly converts light energy into electrical energy.

[0069] The two component frames 10 are arranged opposite to each other along the first direction X, and each component frame 10 extends along the second direction Y, and the photovoltaic component 200 is used to be installed between the two opposite component frames 10. Exemplarily, the first direction X can be the width direction or length direction of the photovoltaic component 200, the corresponding second direction Y is the length direction or width direction of the photovoltaic component 200, and the third direction Z is the thickness direction of the photovoltaic component 200, that is, the third direction Z is perpendicular to the light-receiving surface of the photovoltaic component 200. To facilitate understanding of the present application scheme, the following description is made by taking the first direction X as the width direction of the photovoltaic component 200, the second direction Y as the length direction of the photovoltaic component 200, and the third direction Z as the thickness direction of the photovoltaic component 200 as an example, wherein the first direction X, the second direction Y and the third direction Z are orthogonal to each other.

[0070] There are at least two supports 20, and all supports 20 are used to cooperate with two module frames 10 respectively. When installing the photovoltaic module 200, the support 20 can be connected to the roof panel 300, and then connected to the roof through the roof panel 300, or directly integrated on the roof. Figure 1 Three supports 20 are arranged on the component frames 10 on both sides of the photovoltaic component 200 , and the supports 20 on both sides of the photovoltaic component 200 are distributed one by one to enhance the installation stability of the photovoltaic component 200 .

[0071] Reference Figure 1 2(a) and 2(b), each component frame 10 includes a first plug-in portion 11, and each support 20 includes a second plug-in portion 21. The first plug-in portion 11 and the second plug-in portion 21 can be plugged into each other to connect the component frame 10 and the support 20. In addition, the first plug-in portion 11 is configured to be plugged into the corresponding second plug-in portion 21 along the same direction in the first direction X. For example, the same direction can refer to the direction from Figure 1 The left side of the horizontal direction points to the right, or from Figure 1 The right side of the horizontal line points to the left side.

[0072] Through the above structural design, when the photovoltaic assembly 200 is installed on some usage scenarios such as the roof panel 300 through the installation structure 100, for example, referring to Figure 3(a) to Figure 3(b) The two component frames 10 can be connected to the photovoltaic component 200 respectively, and the support 20 can be pre-assembled on the roof panel 300. Then, the two component frames 10 and the photovoltaic component 200 can be plugged into the support 20 in the same direction in the first direction X, so that the first plug-in portion 11 of the component frame 10 is correspondingly plugged into the second plug-in portion 21 of the support 20, and the photovoltaic component 200 can be installed and fixed.

[0073] Therefore, when the mounting structure 100 provided in the embodiment of the present application is used to install the photovoltaic module 200, it is only necessary to apply an external force in the same direction in the first direction X to connect the module frame 10 and the photovoltaic module 200 to the support 20; when the photovoltaic module 200 needs to be disassembled, it is only necessary to apply a force in the opposite direction to the external force to pull the module frame 10 and the photovoltaic module 200 out of the bracket; the operation is simple, the installation and disassembly efficiency is high, and it is conducive to the rapid disassembly and assembly of the photovoltaic module 200. In addition, after the photovoltaic module 200 is installed, the support 20 and most of the module frame 10 are covered by the photovoltaic module 200, which has a certain aesthetic and ornamental value.

[0074] As a further preferred implementation scheme, based on the above scheme, the specific embodiments of the present application may also include one or more of the following additions or combinations.

[0075] In order to ensure that the component frame 10 is firmly connected to the support 20, when the first plug-in portion 11 and the second plug-in portion 21 are plugged together, at least a portion of the first plug-in portion 11 can be inserted into the second plug-in portion 21, or at least a portion of the second plug-in portion 21 can be inserted into the first plug-in portion 11, or at least a portion of the first plug-in portion 11 can be inserted into the second plug-in portion 21 while at the same time at least a portion of the second plug-in portion 21 is inserted into the first plug-in portion 11.

[0076] For example, in some optional embodiments, the first plug-in portion 11 is formed with a first plug-in port 11a, and the first plug-in port 11a is used to receive at least part of the second plug-in portion 21, and all the first plug-in ports 11a have the same opening direction in the first direction X. At this time, the plug-in function can be realized by inserting at least part of the second plug-in portion 21 into the first plug-in port 11a of the first plug-in portion 11 in the opening direction of the first plug-in port 11a, so as to facilitate efficient installation of the photovoltaic module 200.

[0077] For example, in some optional embodiments, the second plug-in portion 21 is formed with a second plug-in port 21a, and the second plug-in port 21a is used to receive at least part of the first plug-in portion 11, and all the second plug-in ports 21a have the same opening direction in the first direction X. At this time, the plug-in function can be realized by inserting at least part of the first plug-in portion 11 into the second plug-in port 21a of the second plug-in portion 21 in the opening direction of the second plug-in port 21a, so as to facilitate efficient installation of the photovoltaic module 200.

[0078] Also for example, in some optional embodiments, referring to Figure 45(a) and 5(b), the first plug-in portion 11 is formed with a first plug-in interface 11a similar to the above-mentioned structural design, and the second plug-in portion 21 is formed with a second plug-in interface 21a similar to the above-mentioned structural design. The first plug-in portion 11 and the second plug-in portion 21 are plugged into each other through the first plug-in interface 11a and the second plug-in interface 21a, which can further enhance the connection stability between the component frame 10 and the support 20, so as to facilitate the stable installation of the photovoltaic component 200.

[0079] Further, in some optional embodiments, when the first plug-in portion 11 is formed with a first plug-in port 11a, and the second plug-in portion 21 is formed with a second plug-in port 21a, the spacing between the first plug-in ports 11a of the two first plug-in portions 11 opposite to each other in the first direction X is equal to the spacing between the second plug-in ports 21a of the two second plug-in portions 21 that match therewith. Thus, when the first plug-in ports 11a of the two opposite first plug-in portions 11 are just plugged in with the corresponding parts of the two second plug-in portions 21, the second plug-in ports 21a of the two second plug-in portions 21 are also just plugged in with the corresponding parts of the two opposite first plug-in portions 11, that is, the first plug-in ports 11a and the second plug-in ports 21a play a plug-in role synchronously, which can ensure that the plug-in process is carried out smoothly, so as to facilitate stable plug-in.

[0080] In some optional embodiments, the component frame 10 further includes a first mounting portion 12 , the first mounting portion 12 is surrounded by a mounting groove 121 , the mounting groove 121 is used to install the photovoltaic component 200 , and the first plug-in portion 11 is disposed on the outer side of the mounting groove 121 .

[0081] 6(a) and 6(b), Figure 7 , Figure 9(a) and Figure 9(b) and Fig.10 12(a) and 12(b), the mounting groove 121 formed by the first mounting portion 12 is in a roughly C-shaped structure, and the opening directions of the mounting grooves 121 on the two component frames 10 are opposite, so as to facilitate the mounting grooves 121 on the two component frames 10 to be respectively engaged with the two sides of the photovoltaic component 200. The first mounting portion 12 and the first plug-in portion 11 are sequentially arranged along the third direction Z, so as to avoid interference between the first plug-in portion 11 and the second plug-in portion 21 of the support 20 after the photovoltaic component 200 is installed on the first mounting portion 12.

[0082] Since the two component frames 10 need to be plugged into the support 20 in the same direction in the first direction X, the structures of the two component frames 10 can be designed to be the same or different.

[0083] 6(a) and 6(b), the two component frames 10 can be designed as different structures, so that the plug-in operation between the two component frames 10 and different supports 20 is more flexible. Specifically, the first plug-in portion 11 of the left component frame 10 can include a first matching portion 111 and a first connecting portion 112, the first matching portion 111 is spaced apart from the first mounting portion 12 in the third direction Z, and the first connecting portion 112 extends along the third direction Z and is connected to the first mounting portion 12 and the first matching portion 111 to form a first plug-in interface 11a together. The first plug-in portion 11 of the right component frame 10 includes a first matching portion 111 and a first connecting portion 112, the first mounting portion 12 is spaced apart from the first matching portion 111 along the third direction Z, and the first connecting portion 112 extends along the third direction Z and is connected to the first matching portion 111 and the first mounting portion 12 to form a first plug-in interface 11a together. Among them, the opening directions of the first plug-in interface 11a formed by the left component frame 10 and the first plug-in interface 11a formed by the right component frame 10 are both along the first direction X and from the right side to the left side, and the first matching portion 111 of the left component frame 10 and the first matching portion 111 of the right component frame 10 both protrude from the corresponding first connecting portion 112 along the first direction X. Thus, force can be applied from right to left to make the first plug-in interface 11a of the component frame 10 plug into the corresponding part of the support 20, and at the same time, the first matching portion 111 of the component frame 10 plugs into the corresponding second plug-in interface 21a on the support 20, so as to connect the component frame 10 with the support 20, which is conducive to improving the installation stability of the photovoltaic component 200.

[0084] 9(a) and 9(b), the two component frames 10 are designed to have the same structure, so as to facilitate batch manufacturing of component frames 10 and support 20, improve production efficiency and reduce production costs. Specifically, the first plug-in portion 11 of the left component frame 10 and the first plug-in portion 11 of the right component frame 10 may include a first matching portion 111 and a first connecting portion 112, the first mounting portion 12 and the first matching portion 111 are arranged at intervals along the third direction Z, and the first connecting portion 112 is extended along the third direction Z. The top end of the first connecting portion 112 is connected to the middle part of the first mounting portion 12 in the first direction X, and the bottom end of the first connecting portion 112 is connected to the middle part of the first matching portion 111 in the first direction X, so that the left component frame 10 shown in FIG. 9(a) and the right component frame 10 shown in FIG. 9(b) have the same structure and are centrally symmetrically distributed. Since the installation directions of the left component frame 10 and the right component frame 10 are the same, at this time, the left component frame 10 and the right component frame 10 can both form a C-shaped first plug-in port 11a surrounded by the first matching portion 111, the first connecting portion 112 and the first mounting portion 12. Among them, the two ends of the first connecting portion 112 are respectively connected to the middle parts of the first matching portion 111 and the first mounting portion 12, so that the two ends of the first matching portion 111 and the first mounting portion 12 in the first direction X both protrude from the first connecting portion 112. Therefore, no matter whether the component frame 10 is connected to the left or right side of the photovoltaic component 200, the end of the first matching portion 111 can be plugged into the second plug-in port 21a of the support 20, thereby realizing the installation and fixation of the photovoltaic component 200.

[0085] Referring to Figures 12(a) and 12(b) again, the two component frames 10 are also designed to have the same structure. Specifically, the first plug-in portion 11 of the left component frame 10 and the first plug-in portion 11 of the right component frame 10 may include a first matching portion 111, a first connecting portion 112 and a second matching portion 113, the second matching portion 113 is connected to the first mounting portion 12, the first matching portion 111 is spaced apart from the second matching portion 113 in the third direction Z, the first connecting portion 112 extends along the third direction Z and is connected to the second matching portion 113 and the first matching portion 111 to form a first plug interface 11a together. Among them, both ends of the first matching portion 111 in the first direction X protrude from the first connecting portion 112 (that is, the first matching portion 111 is the entire portion located below the first connecting portion 112), so that the first matching portion 111 can be used to achieve plug-in matching with the support 20.

[0086] Specifically, referring to Figures 11(a) and 11(b), the first matching portion 111 of the first plug-in portion 11 of the left component frame 10 protrudes from one end of the first connecting portion 112 and is received in the second plugging port 21a formed by the second plug-in portion 21 of the left support 20, and at the same time, part of the second plug-in portion 21 of the left support 20 is received in the first plugging port 11a of the left component frame 10, and the first matching portion 111 of the first plug-in portion 11 of the right component frame 10 protrudes from the other end of the first connecting portion 112 and is received in the second plugging port 21a formed by the second plug-in portion 21 of the right support 20, and at the same time, the card groove 321 on the second plug-in portion 21 of the right support 20 is card-connected with the card protrusion 322 on the first matching portion 111.

[0087] Further, referring to FIG. 12(a) and FIG. 12(b), in some optional embodiments, the first plug-in portion 11 may further include a connecting support portion 114, which extends along the third direction Z and is connected to the first matching portion 111 and the first mounting portion 12, so that the connecting support portion 114, the first matching portion 111, the first connecting portion 112, the second matching portion 113 and the first mounting portion 12 are connected to form a hollow frame-like structure, and the hollow frame-like structure is used to enclose the first plug-in port 11a for plugging with the corresponding part of the support 20. In addition, the gap between the component frame 10 and the support 20 can be filled as much as possible through the hollow frame-like structure, so that the component frame 10 and the support 20 are closely fitted, so as to facilitate the support 20 to form a stable and reliable support for the component frame 10 and the photovoltaic component 200.

[0088] In addition, the structure of the second plug-in portion 21 of the support 20 may also be optimized accordingly.

[0089] In some optional embodiments, the second plug-in portion 21 includes a third mating portion 211, a second connecting portion 212 and a fourth mating portion 213, the third mating portion 211 and the fourth mating portion 213 are spaced apart along a third direction Z, the second connecting portion 212 extends along the third direction Z and is connected to the third mating portion 211 and the fourth mating portion 213, and the fourth mating portion 213 is arranged beyond the third mating portion 211 in the first direction X; the third mating portion 211, the second connecting portion 212 and the fourth mating portion 213 together form a second plug interface 21a.

[0090] Referring to Fig. 6(c) and Fig. 6(d), Fig. 9(c) and Fig. 9(d), and Fig. 12(c) and Fig. 12(d), the third mating portion 211 is used to be arranged on a side close to the photovoltaic assembly 200, and the fourth mating portion 213 is used to be arranged on a side away from the photovoltaic assembly 200. The third mating portion 211, the second connecting portion 212, and the fourth mating portion 213 together form a C-shaped second plug interface 21a for plugging with the corresponding portion of the first plug portion 11. In addition, the fourth mating portion 213 protrudes from the second mating portion 113 along the first direction X. Before plugging, the first plug portion 11 can be placed on the fourth mating portion 213, and then force is applied to the first plug portion 11 to push the first plug portion 11 to slide on the fourth mating portion 213 until it is inserted into the second plug interface 21a. Therefore, the plugging direction of the first plugging portion 11 can be limited by the fourth matching portion 213, so that the first plugging portion 11 can be accurately plugged with the second plug interface 21a.

[0091] Optionally, the ratio of the length of the portion of the fourth mating portion 213 that exceeds the third mating portion 211 in the first direction X to the length of the first plug-in portion 11 in the first direction X is greater than 1 / 2. For example, the ratio of the length of the portion of the fourth mating portion 213 that exceeds the third mating portion 211 in the first direction X to the length of the first plug-in portion 11 in the first direction X may be 2 / 3, 3 / 4, 4 / 5, 5 / 6, etc. At this time, when the first plug-in portion 11 is placed on the fourth mating portion 213, the fourth mating portion 213 can form a more stable support for the first plug-in portion 11, so as to facilitate the installation of the component frame 10 and the photovoltaic component 200.

[0092] In some optional embodiments, the third matching portion 211 is a plate-like structure; referring to FIG. 12( c ), the plate-like structure is extended along the first direction X so as to form a C-shaped second plug interface 21 a together with the second connecting portion 212 and the fourth matching portion 213 .

[0093] In other optional embodiments, the third mating portion 211 includes a first extension portion 211a, a second extension portion 211b and a third extension portion 211c, the first extension portion 211a and the third extension portion 211c extend along the first direction X and are spaced apart along the third direction Z, and the second extension portion 211b extends along the third direction Z and is connected to the first extension portion 211a and the third extension portion 211c.

[0094] 6(c) and 6(d), 9(c) and 9(d), the first extension portion 211a, the second extension portion 211b and the third extension portion 211c are connected to form a C-shaped structure, and the C-shaped structure is connected with the second connection portion 212 and the fourth matching portion 213 to form an S-shaped structure. In the process of plugging the first plug-in portion 11 with the second plug-in portion 21, the first extension portion 211a, the second extension portion 211b and the third extension portion 211c included in the second plug-in portion 21 are integrally plugged into the first plug port 11a of the first plug-in portion 11, and support the first plug-in portion 11, so that the stability of the photovoltaic module 200 on the mounting structure 100 can be enhanced.

[0095] In order to ensure that the first plug-in portion 11 and the second plug-in portion 21 can be firmly plugged in, the plug-in method of the first plug-in portion 11 and the second plug-in portion 21 can be optimized.

[0096] In some optional embodiments, when the first plug-in portion 11 is provided with a first plug-in port 11a, at least a portion of the second plug-in portion 21 abuts against the inner wall of the first plug-in port 11a in the third direction Z to lock the positions of the first plug-in portion 11 and the second plug-in portion 21 in the third direction Z. Exemplarily, the thickness of at least a portion of the second plug-in portion 21 in the third direction Z may be slightly greater than the thickness of the opening of the first plug-in port 11a in the third direction Z. At this time, after at least a portion of the second plug-in portion 21 is plugged into the first plug-in port 11a along the first direction X, the second plug-in portion 21 may be tightly connected to the first plug-in port 11a by interference fit.

[0097] Similarly, in some optional embodiments, when the second plug-in portion 21 is provided with a second plug interface 21a, at least a portion of the first plug-in portion 11 abuts against an inner wall of the second plug interface 21a in the third direction Z. For example, the first plug-in portion 11 can be tightly connected to the second plug interface 21a by an interference fit to lock the positions of the first plug-in portion 11 and the second plug-in portion 21 in the third direction Z.

[0098] Similarly, in some optional embodiments, when the first plug-in portion 11 is provided with a first plug interface 11a and the second plug-in portion 21 is provided with a second plug interface 21a, at least a portion of the second plug-in portion 21 abuts against an inner wall of the first plug interface 11a in the third direction Z, and at the same time, at least a portion of the first plug-in portion 11 abuts against an inner wall of the second plug interface 21a in the third direction Z, for example, the first plug interface 11a and the second plug-in portion 21 have at least a partial interference fit, and at the same time, the second plug interface 21a and the first plug-in portion 11 have at least a partial interference fit, so as to lock the positions of the first plug-in portion 11 and the second plug-in portion 21 in the third direction Z, thereby further improving the plug-in stability of the first plug-in portion 11 and the second plug-in portion 21.

[0099] Furthermore, in some optional embodiments, the mounting structure 100 further includes a locking structure 30 for locking the positions of the first plug-in portion 11 and the second plug-in portion 21 in the first direction X to further enhance the plugging stability between the first plug-in portion 11 and the second plug-in portion 21 .

[0100] In some optional embodiments, the locking structure 30 is a fastener 31 , and the fastener 31 is passed through the first plug-in portion 11 and the second plug-in portion 21 to lock and connect the first plug-in portion 11 and the second plug-in portion 21 .

[0101] For example, referring to Fig. 3(c), Fig. 5(a) and Fig. 5(b), and Fig. 8(a) and Fig. 8(b), the fastener 31 may include a bolt and a nut, and a through hole for matching with the bolt is preset on both the first plug-in portion 11 and the second plug-in portion 21. After the first plug-in portion 11 and the second plug-in portion 21 are plugged in, the bolt is passed through the through hole on the first plug-in portion 11 and the second plug-in portion 21, and then matched with the nut to lock the first plug-in portion 11 and the second plug-in portion 21, and the locking operation is simple and efficient.

[0102] In some optional embodiments, the locking structure 30 is a snap-fit ​​structure 32 , which is disposed on the first plug-in portion 11 and / or the second plug-in portion 21 to snap-fit ​​the first plug-in portion 11 and the second plug-in portion 21 .

[0103] Exemplarily, in some optional embodiments, the snap-fit ​​structure 32 includes a snap-fit ​​groove 321 and a snap-fit ​​protrusion 322, the first plug-in portion 11 is formed with a snap-fit ​​groove 321 or a snap-fit ​​protrusion 322, and the second plug-in portion 21 is formed with a snap-fit ​​protrusion 322 or a snap-fit ​​groove 321; the second plug-in portion 21 is snap-fitted to the first plug-in portion 11 through the cooperation between the snap-fit ​​protrusion 322 and the snap-fit ​​groove 321.

[0104] Specifically, referring to FIG. 11(a) and FIG. 11(b) and Figure 12(a) to Figure 12(d), a cam 322 is formed at the end of the first matching portion 111 of the first plug-in portion 11, and the cam 322 protrudes from other parts of the first matching portion 111 in the third direction Z. Correspondingly, referring to FIG. 12(d) again, the third matching portion 211 of the second plug-in portion 21 includes a first section 211d, a second section 211e and a third section 211f connected in sequence along the first direction X, wherein the connection between the first section 211d and the second section 211e protrudes upward along the third direction Z, thereby forming a cam 321 together with the second connecting portion 212 and the fourth matching portion 213, and the cam 321 is used to cooperate with the cam 322 of the first plug-in portion 11, so that the second plug-in portion 21 and the first plug-in portion 11 can be firmly plugged. In addition, the third section 211f of the second plug-in portion 21 is tilted upward from the second section 211e, so that the cam 322 of the first matching portion 111 can be guided for quick plugging. It should be understood that the first section 211d, the second section 211e and the third section 211f can all be configured as plate-like structures with a certain degree of deformation capability, so that the latching protrusion 322 can smoothly enter the latching groove 321.

[0105] It is understandable that in other optional embodiments, a card slot 321 may be provided on the first plug-in portion 11, and correspondingly, a card protrusion 322 may be provided on the second plug-in portion 21, so that a snap connection can also be achieved.

[0106] In addition, in some optional embodiments, the support 20 further includes a second mounting portion 22 , the second mounting portion 22 protrudes from the second plug-in portion 21 in the third direction Z, and the second mounting portion 22 is used to connect the roof panel 300 .

[0107] Exemplarily, the second mounting parts 22 of the support 20 are all tilted, and the second mounting parts 22 are connected to the roof panel 300 by bolts. In addition, the tilt direction of the second mounting part 22 of the support 20 located on the left side of the photovoltaic module 200 is opposite to the tilt direction of the second mounting part 22 of the support 20 located on the right side of the photovoltaic module 200, so as to match the structure of the support 20 with the roof panel 300, thereby stably mounting the photovoltaic module 200 on the roof panel 300.

[0108] Reference Figure 1 and Fig.13Another embodiment of the present application also provides a photovoltaic component 1000, including a photovoltaic module 200, a roof panel 300 and the mounting structure 100 of any of the above embodiments. Among them, the photovoltaic module 200 is usually composed of a plurality of photovoltaic cells, which are used to convert sunlight into electrical energy; its light-receiving surface faces the outside, and the backlight surface faces the roof panel 300, and may include stacked photovoltaic tempered glass, EVA film or POE film, photovoltaic cell strings and photovoltaic backboard or photovoltaic backboard glass and other structures for photovoltaic power generation. Of course, the photovoltaic module 200 can also be composed of other structures, and the present application does not specifically limit the specific structure of the photovoltaic module 200.

[0109] 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 structural parts of the construction.

[0110] Further, along the second direction Y, the photovoltaic assembly 200 is connected to the roof panel 300 through the mounting structure 100. The photovoltaic assembly 200 may be one, or a plurality of photovoltaic assemblies 200 are sequentially arranged on the roof panel 300 along the second direction Y. The second direction Y is the extension direction of the roof panel 300. For example, the second direction Y can also be understood as the length direction of the roof panel 300 or the photovoltaic assembly 200.

[0111] The end of the support 20 away from the second plug-in portion 21 also includes a second mounting portion 22, and the second mounting portion 22 is used to be fixedly connected to the roof panel 300. The second mounting portion 22 is arranged on the side of the second plug-in portion 21 away from the first plug-in portion 11 in the third direction Z and is fixedly connected to the roof panel 300, and the third direction Z is perpendicular to the light-receiving surface of the photovoltaic module 200.

[0112] In some optional embodiments, along the second direction Y, the number of photovoltaic modules 200 installed on the roof panel 300 is any one of 1 to 3, and each photovoltaic module 200 is connected to the roof panel 300 through no less than 4 supports 20. Specifically, 1, 2 or 3 photovoltaic modules 200 can be installed on the roof panel 300 along the second direction Y, and each photovoltaic module 200 can be connected to the roof panel 300 through 4, 5, 6 or more supports 20, so as to stably install the photovoltaic module 200 on the roof panel 300.

[0113] Reference Fig.13In some optional embodiments, the roof panel 300 includes a panel body 301 and an assembly portion 302; the assembly portions 302 are located on both sides of the panel body 301 in the first direction X and protrude from the panel body 301 in the third direction Z, and each assembly portion 302 is used to install the second installation portion 22 of the corresponding support 20. Specifically, the panel body 301 is the main part of the roof panel 300 and is used to form the bottom support of the photovoltaic component 1000. The assembly portion 302 is connected to and protrudes from the panel body 301, and is used to connect with the support 20, so as to facilitate the installation of the photovoltaic component 200 on the roof panel 300.

[0114] In some optional embodiments, the plate body 301 is provided with at least one convex rib 303 protruding from the plate body 301 along a third direction Z, i.e., a height direction. The convex rib 303 is optionally a trapezoidal structure, which can be used to contact the bottom surface of the photovoltaic component 200 to provide structural support for the photovoltaic component 200, and can disperse the load and strengthen the structural strength of the photovoltaic component 200, thereby improving the load-bearing capacity of the photovoltaic component 200 and avoiding deformation of the photovoltaic component 200 under stress.

[0115] Furthermore, buffer gaskets are provided between the ribs 303 and the photovoltaic module 200. Since the photovoltaic module 200 is affected by temperature changes during use, and temperature changes cause the photovoltaic module 200 to expand and contract, thereby generating thermal stress. The buffer gasket can provide a certain buffering effect between the ribs 303 and the photovoltaic module 200, reduce the thermal stress caused by temperature changes, and reduce the risk of damage to the photovoltaic module 200; at the same time, the buffer gasket can play a role in structural reinforcement and shock absorption for the photovoltaic module 200, reduce the impact of stress on the photovoltaic module 200, and thus improve the stability and safety of the photovoltaic module 200.

[0116] Refer to Fig.13 In some optional embodiments, the assembly portion 302 includes an inclined surface mounting section 3021 and a plane section 3022, wherein the plane section 3022 and the plate body 301 are spaced apart in the third direction Z, and the plate body 301 is arranged on the side of the plane section 3022 away from the photovoltaic module 200, specifically, the plane section 3022 is closer to the photovoltaic module 200, and the plate body 301 and the plane section 3022 are connected by the inclined surface mounting section 3021, wherein the second mounting portion 22 is mounted at the inclined surface mounting section 3021. Through the inclined guiding effect of the inclined surface mounting section 3021, water retention at the second mounting portion 22 can be prevented in rainy seasons, erosion of the second mounting portion 22 can be reduced, and the reliability and durability of the second mounting portion 22 can be improved.

[0117] Through the above, a first trough body A can be formed between the inclined installation section 3021 and the convex rib 303, and a second trough body B can be formed between multiple convex ribs 303. The first trough body A and the second trough body B can also play a diversion role, so that the accumulated water on the roof panel 300 can be discharged in time along the second direction Y.

[0118] Further, refer to Fig.14 The second mounting portion 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 inclined mounting section 3021, and the fixing pin 222 is arranged through the matching section 221 and the roof panel 300 to connect the support 20 and the roof panel 300. The matching section 221 and the inclined mounting section 3021 match each other to provide a stable mounting surface for connection, and the fixing pin 222 passes through the matching section 221 and the roof panel 300 to connect the second mounting portion 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 inclined mounting section 3021, 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, and the protective layer 223 can play a certain role in preventing loosening.

[0119] Furthermore, one end of the roof panel 300 is a male locking edge 304, and the other end is a female locking edge 305, wherein the male locking edge 304 is respectively arranged on the side of the assembly portion 302 away from the plate body 301, and the adjacent roof panels 300 are overlapped and screwed through the male locking edge 304 and the female locking edge 305, and the installer can quickly and accurately connect the roof panels 300 together. This can save installation time and labor costs and improve construction efficiency. In addition, the overlap structure of the male locking edge 304 and the female locking edge 305 can ensure that the roof panels 300 are tightly connected.

[0120] Reference Figure 1 First, the support 20 is installed on both sides of the roof panel 300 along the first direction X, and there are at least two supports 20 on each side. The specific configuration can be adaptive according to the photovoltaic components 200 to be installed on the roof panel 300. For example, one photovoltaic component 200 requires six supports 20, that is, three supports are fixed on each side. If three photovoltaic components 200 are installed on the roof panel 300 along the second direction Y, 18 supports 20 need to be installed on the roof panel 300. Then, the photovoltaic component 200 pre-installed with the component frame 10 is placed on the fourth matching portion 213 of the support 20 along the third direction Z through the first plug-in portion 11, and then the photovoltaic component 200 is pushed in along the first direction X, and the first plug-in portion 11 is plugged into the second plug-in portion 21 to achieve rapid assembly of the photovoltaic component 1000.

[0121] Another embodiment of the present application further provides a photovoltaic roof system, comprising a plurality of photovoltaic components 1000, and the photovoltaic components 1000 are connected by roof panels 300. That is, the photovoltaic components 1000 are independent monomer structures, and the photovoltaic roof system is formed by moving the plurality of photovoltaic components 1000 to a construction site and connecting them by roof panels 300 at the construction site.

[0122] In another embodiment, the photovoltaic roof system includes the mounting structure 100 as described in the above embodiment, 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 .

[0123] In addition, based on the specific structure of the photovoltaic component 1000 in the above embodiments, it can also be used in a photovoltaic roofing system. For example, the roof panel 300 may include the panel body 301 and the assembly portion 302 in the above embodiments, the panel body 301 may be provided with a convex rib 303, and a buffer gasket may be provided between the photovoltaic component 200 and the convex rib 303 to achieve the same function as described in the above embodiments.
