[0055] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments in the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the embodiments of the present invention.

[0056] It should be noted that in the description of the present invention, the terms "first" and "second" are only used to facilitate the description of different components or names, and cannot be understood as indicating or implying a sequential relationship, relative importance, or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0057] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0058] See also Figure 5 The bracket with a trigger structure provided in the embodiment of the present invention can be used in conjunction with a roof panel. The bracket can cooperate with the limiting structure 14 set on the roof panel to limit the roof panel on the roof purlin 60, so that the roof panel has good wind resistance, and the bracket can be in two states to facilitate installation between the roof panel.

[0059] First, let me introduce the roof panels used with the bracket. Figure 1 : is a side view structural diagram of a roof panel in an embodiment of the present invention, Figure 2 FIG. 1 is a schematic diagram of a three-dimensional structure of a roof panel in an embodiment of the present invention. Figure 1 and Figure 2 shown.

[0060] The embodiment of the present invention provides a roof panel, comprising: a main section 10 and a side section 20. The main section 10 is provided with a wave crest structure 11, the wave crest structure 11 has a first bearing surface 12 and a limiting space 13, and limiting structures 14 are respectively provided on both sides of the wave crest structure 11. Side sections 20 are respectively provided on opposite sides of the main section 10, and each side section 20 is respectively provided with a second bearing surface 21 and a locking structure 22. The locking structure 22 on one side of the roof panel can be locked with the locking structure 22 on the other side of the adjacent roof panel.

[0061] The technical solution provided by the embodiment of the present invention is shown in Figure 3and Figure 4 The first bearing surface 12 on the wave crest structure 11 and the second bearing surface 21 on the side segment 20 can integrate the photovoltaic module 30 on the roof panel. Figure 5 By setting a limiting structure 14 on the crest structure 11 of the roof panel, the limiting structure 14 cooperates with a corresponding bracket structure, which is a bracket with a trigger structure, also called a middle bracket 40, to limit the roof panel on the roof purlin 60, so that the roof panel has good wind resistance.

[0062] In the embodiment of the present invention, the main body section 10 can be a plane or a non-plane, and can be made into corresponding shapes according to different requirements. For example, when a plane is used, a convex or concave reinforcement structure can be set on the plane to improve the rigidity and strength. The roof panel includes but is not limited to the use of metal plates, which are formed by stamping, rolling and other processes. The metal plate includes a plate with an anti-corrosion layer on the surface to improve the corrosion resistance of the plate. The plate includes but is not limited to a steel plate, and the anti-corrosion layer includes but is not limited to a paint layer, a galvanized layer, etc.

[0063] The side section 20 and the main section 10 can be an integrally formed structure, which is made by a bending process or a stamping process. One forming method is to select a section of a predetermined length at both ends of the main section 10, and then use a bending process to form a Figure 1 Taking the middle position as an example, the side segments 20 are formed by bending upward relative to the main segment 10. Then, taking the side segment 20 on the right side as an example, the side segment 20 is bent upward by a predetermined distance to the right to form a second bearing surface 21, and a bending segment 23 is bent on the second bearing surface 21 to form a drainage channel, and the bending segment 23 is bent upward to form a locking structure 22.

[0064] The peak structure 11 can be formed on the main section 10 by rolling or stamping. The peak structure 11 can be one, two or more, and the photovoltaic panel can be supported by the first bearing surface 12 of the peak structure 11 away from the main section 10. At the same time, the strength of the roof panel can be further enhanced by the peak structure 11. Furthermore, a plurality of reinforcing ribs 15 are evenly arranged side by side at positions different from the convex ridges on the main section 10, and the convex direction of the reinforcing ribs 15 is consistent with the convex direction of the peak structure 11.

[0065] See also Figure 5When the roof system is formed by assembling the roof panel on the roof purlin 60, the roof panel can also be used in conjunction with multiple bracket structures, such as the middle bracket 40 used in conjunction with the wave crest structure 11, and the side bracket 50 used in conjunction with the locking edge structure 22. The middle bracket 40 and the side bracket 50 are respectively fixedly connected to the roof purlin 60 by self-tapping screws. At the same time, the middle bracket 40 is connected to the limiting structure 14 on the wave crest structure 11, and the side bracket 50 is connected to the locking edge structure 22, so that the roof panel is limited by the middle bracket 40 and the side bracket 50, thereby improving the wind resistance of the roof panel.

[0066] Continue to see Figure 5 In an embodiment of the present invention, one implementation of the middle bracket 40 is that the middle bracket 40 includes a base 41 and a connector 42. The connector 42 can be set in the limiting space 13 and cooperate with the limiting structure 14 to limit the relative position between the roof panel and the middle bracket 40. The function of the base 41 is to connect with the roof purlin 60 and provide support for the connector 42. The specific implementation of the base 41 is not specifically limited here, as long as the above functions can be achieved. The function of the connector 42 is to be set in the limiting space 13, and cooperate with the base 41 to constrain the position of the roof panel to ensure that the position and state of the roof panel are stable. Of course, the specific implementation of the connector 42 is not specifically limited here, as long as the above functions can be achieved.

[0067] Further, in some achievable embodiments of the present invention, one implementation of the connector 42 is that the portion of the connector 42 that cooperates with the limiting structure 14 is fixed relative to the base 41, and the shape of the connector 42 matches the shape of the limiting space 13. Another implementation of the connector 42 is that the portion of the connector 42 that cooperates with the limiting structure 14 is rotatable relative to the base 41, and the connector 42 has two states, one of which is a retracted state, in which the wave crest structure 11 on the roof panel can be conveniently buckled on the connector 42, or it can be said that it is convenient for the connector 42 to extend into the limiting space 13. When the connector 42 is converted from the retracted state to the extended state, the connector 42 can be engaged with the limiting structure 14, thereby cooperating with the limiting structure 14 to achieve the limitation of the roof panel.

[0068] Continue to see Figure 1 and Figure 2In order to facilitate supporting the photovoltaic component 30, the first bearing surface 12 and the second bearing surface 21 are located in the same plane. Since the first bearing surface 12 and the second bearing surface 21 are located in the same plane, when installing the photovoltaic component 30, the two ends of the photovoltaic component 30 are respectively matched and abutted on the second bearing surfaces 21 on both sides, and the middle part of the photovoltaic component 30 is matched and supported on the first bearing surface 12, which can better support the photovoltaic component 30. When the supporting effect is good, the requirements for the strength of the photovoltaic component 30 itself can be reduced. With the reduction of the requirements for its own strength, the thickness of the photovoltaic component 30 itself can be reduced to reduce weight and manufacturing costs. Generally, the thickness of the photovoltaic component 30 itself can be reduced by reducing the thickness of the glass packaging board on the front of the photovoltaic component 30. With the reduction of the thickness of the glass packaging board on the front, the light transmittance of the photovoltaic component 30 is enhanced, and the photoelectric conversion efficiency is also improved.

[0069] Furthermore, one way to connect the photovoltaic module 30 to the roof panel is that the photovoltaic module 30 is bonded to the first bearing surface 12 and the second bearing surface 21 of the roof panel. For example, the photovoltaic module 30 can be bonded to the first bearing surface 12 and the second bearing surface 21 by means of adhesive or tape, etc. This method has the effect of convenient operation. The adhesive can be a silicone structural adhesive or other materials, and the tape can be a pressure-sensitive adhesive or tape of other materials.

[0070] Another way to connect the photovoltaic module 30 to the roof panel is to Figure 6 , the photovoltaic component 30 can be fixed on the roof panel by a clamp assembly. One possible implementation of the clamp assembly is that the clamp assembly includes a middle clamp 70 assembly and a side clamp 71. The middle clamp 70 assembly is connected to the crest structure 11 on the roof panel, and forms a first clamping structure with the first bearing surface 12 to limit the photovoltaic component 30. The side clamp 71 is connected to the locking structure 22 on the roof panel, and forms a second clamping structure with the second bearing surface 21 to limit the photovoltaic component 30. Based on the clamping effect of the clamp assembly, the photovoltaic component 30 can be effectively fixed and the stability of the photovoltaic component 30 can be improved. Furthermore, the bonding method can be used in conjunction with the clamp assembly, that is, while the photovoltaic component 30 is bonded to the roof panel, the photovoltaic component 30 is fixed again by the clamp assembly, so that the position of the photovoltaic component 30 is more stable.

[0071] In order to further ensure the drainage function of the roof system, one achievable method is that a bending section 23 is provided on the side section 20, and the bending section 23 is located between the second bearing surface 21 and the locking edge structure 22. The bending section 23 is bent downward relative to the second bearing surface 21, and rainwater falling on the roof system can flow away through the bending section 23 to ensure the drainage function of the roof system. Rainwater falling on the roof panel can flow away through the gap between the main section 10 and the photovoltaic module 30. At the same time, a heat dissipation channel can be formed through the gap between the main section 10 and the photovoltaic module 30 to allow air circulation to ensure the heat dissipation performance of the roof system. Further, in order to ensure that the formed heat dissipation channel has sufficient heat dissipation performance, the distance between the main section 10 and the photovoltaic module 30 can be set according to different requirements, such as being greater than 2 cm. This distance is set so that the heat dissipation channel has a sufficient cross-sectional area to ensure sufficient air flow to dissipate heat from the photovoltaic module 30.

[0072] Continue to see Figure 1 and Figure 2 One possible implementation of the crest structure 11 is that the crest structure 11 includes a top plate and two side plates, and a first bearing surface 12 is provided on the top plate. The limiting structure 14 is a groove structure located on the side plate and recessed toward the limiting space 13. In this arrangement, the groove structures on the two side plates extend in opposite directions, or in other words, the groove structures extend toward the limiting space 13 enclosed by the two side plates. The groove structure can accommodate the connector 42 of the middle bracket 40, and the connector 42 can constrain the roof panel to prevent the position and state of the roof panel from changing.

[0073] Further, in order to achieve a better limiting effect between the limiting groove and the connector, continue to refer to Figure 1 and Figure 2 , the groove structure extends horizontally or gradually tilts toward the plane where the top plate is located. In this arrangement, the groove structure can better engage with the connector 42 on the middle bracket 40, and it is easier to exert force on each other. When the roof panel tends to move upward in the wind, the groove structure cooperates with the connector 42 to more easily exert a downward force on the roof panel, thereby better preventing the roof panel from moving upward.

[0074] In order to further improve the strength of the roof panel, a plurality of reinforcing ribs 15 are provided on the main section 10, and the extension direction of each reinforcing rib 15 intersects with the length direction of the main section 10. The reinforcing rib 15 can be formed on the main section 10 by rolling or stamping process, and one, two or more reinforcing ribs 15 can be provided. When two or more reinforcing ribs 15 are provided, the intervals between adjacent reinforcing ribs 15 can be equal or unequal. As the number of reinforcing ribs 15 increases, the strength of the roof panel will also increase accordingly. In the embodiment of the present invention, the reinforcing ribs 15 include but are not limited to shapes such as long strips, trapezoids, and crosses. Furthermore, in order to achieve a better strengthening effect, the extension direction of each reinforcing rib 15 is perpendicular to the length direction of the main section 10.

[0075] In the embodiment of the present invention, a construction method of the roof panel is as follows: Figure 1 Taking the central position as an example, we define: Figure 1 The left and right directions in the figure are the length directions of the roof panels. Figure 1 The direction perpendicular to the paper surface is the width direction of the roof panel.

[0076] During construction, first, multiple support structures are spaced apart along the length direction of the roof panel and fixed to the roof purlin 60, and the fixing method includes but is not limited to fixing by self-tapping screws. Multiple support structures arranged at intervals can be set corresponding to different limit spaces 13. For example, the middle support 40 is set corresponding to the limit space 13 of the wave crest structure 11, and the side support 50 is set corresponding to the lock edge structure 22. Furthermore, for one limit space 13, the corresponding connected middle support 40 can be one, and one middle support 40 extends along the width direction of the roof panel and runs through the entire limit space 13. There can also be multiple middle supports 40, and multiple middle supports 40 are spaced apart along the width direction of the roof panel and connected corresponding to the same limit space 13. In the embodiment of the present invention, the description is taken as an example that one limit space 13 corresponds to one support structure, which does not constitute an improper limitation of the embodiment of the present invention.

[0077] Secondly, the roof panel is assembled between the two side brackets 50 arranged at intervals along the length direction. Since the roof panel can be made of metal plates, the side section 20 has a certain elasticity relative to the main section 10. Therefore, the roof panel can be inserted between the two side brackets 50 by extrusion and buckled on the middle bracket 40 through the wave peak structure 11. After the middle bracket 40 enters the limiting space 13, it can be connected to the limiting structure 14 to limit the position of the roof panel.

[0078] After assembly, the locking structures 22 on two adjacent roof panels can be locked together. After assembly, the connector 42 on the middle bracket 40 of the roof panel is located in the limiting space 13. The limiting space 13 provides the roof panel with a limiting structure 14 for wind resistance, and the limiting structure 14 is connected to the middle bracket 40. When the roof panel is "lifted by wind" in a windy environment, the limiting structure 14 cooperates with the middle bracket 40, and the side bracket 50 cooperates with the locking structure 22 to jointly resist the "lifting by wind", ensuring that the roof panel remains stable, thereby significantly improving the wind resistance of the roof panel and the roof system formed by it.

[0079] Furthermore, after the adjacent roof panels are assembled, the locking structure 22 on one side of the roof panel can be locked with the locking structure 22 on the other side of the adjacent roof panel. The locking method includes but is not limited to wrapping one locking structure 22 with another locking structure 22 and bending it inward, so that the locking seam is a full-length gapless locking seam, ensuring that the locking seam has a good waterproof effect. Of course, the degree of bending of the locking seam can also be increased to achieve better waterproof performance. The two sides of the roof panel adopt a 360-degree (or more) gapless locking seam waterproofing method, and a limiting structure 14 is set at the same time to provide a wind-resistant curved bearing surface, and the support structure is used for wind resistance.

[0080] In the embodiment of the present invention, there are many ways to implement the support structure, one of which can be implemented as follows: Figures 7 to 9 One implementation of the support structure in the embodiment of the present invention is that the support structure is a support with a trigger structure, including: a base 41, a support rod 421, at least one pair of limit hinges 422 and a trigger device 423. Among them, the support rod 421 is arranged on the base 41. The limit hinge 422 is rotatably arranged on the support rod 421, and a limit portion 43 is arranged on the limit hinge 422, and an elastic member 4221 is arranged between the pair of limit hinges 422. The limit hinge 422 is a connector 42 connected to the limit structure 14. The trigger device 423 is arranged on the base 41.

[0081] See also Fig.10 When the trigger device 423 is in the first position, at least one pair of limit hinges 422 is constrained to a folded state. When the limit hinges 422 are in the folded state, the assembly between the bracket and the wave crest structure 11 can be facilitated. Fig.11 When the trigger device 423 is in the second position, at least one pair of limit hinges 422 is converted from the folded state to the unfolded state under the elastic force of the elastic member 4221. When the pair of limit hinges 422 are in the unfolded state, they can cooperate with the limit structure 14 on the crest structure 11 to limit the roof panel on the roof purlin, so that the roof panel has good wind resistance, and the limit hinges 422 on the bracket can be in two states for easy installation with the roof panel.

[0082] Combination Figure 8 and Fig. 9 , see Fig.12 One possible implementation of the base 41 is that the base 41 includes a connecting portion 411 and a boss 412, and there is a height difference between the connecting portion 411 and the boss 412. The connecting portion 411 is used to connect and fix with the roof purlin to fix the position of the entire bracket. In order to facilitate the connection of the connecting portion 411, a hole structure is preset on the connecting portion 411, and the connection between the connecting portion 411 and the roof purlin can be achieved by self-tapping screws. The boss 412 is higher than the connecting portion 411 so as to cooperate with the trigger device 423 so that the trigger device 423 can achieve the conversion between the first position and the second position. The support rod 421 and the trigger device 423 are both arranged on the boss 412. The base 41 and the limit hinge 422 are integrated together by the support rod 421, and the limit hinge 422 can rotate around the support rod 421 to achieve the conversion between the folded state and the unfolded state.

[0083] Furthermore, combined with Figure 8 and Fig. 9 , see Fig.13 , two ends of the support rod 421 are respectively provided with limiting nuts 4211. The boss 412 of the base 41 is provided with a mounting hole, and one end of the support rod 421 can pass through the mounting hole and connect the limiting nut 4211. After the limiting hinge 422 and the elastic member 4221 are assembled on the support rod 421, another limiting nut 4211 is connected to the other end of the support rod 421, so that the limiting hinge 422 and the elastic member 4221 are limitedly connected between the limiting nuts 4211 at both ends.

[0084] See also Fig.14 and Fig.15 In the embodiment of the present invention, the implementation methods of the paired limiting folding edges 431 are roughly the same. One possible implementation method is that the limiting hinge 422 includes a hinge body 4222 and a hinge ear 4223, a constraint wall 4224 and a limiting portion 43 arranged on the hinge body 4222. Between the paired limiting hinges 422, the hinge body 4222, the constraint wall 4224 and the limiting portion 43 have the same shape. In order to enable the two to be used in conjunction, the implementation methods of the hinge ears 4223 of the two are different. See Fig.14 , one of the hinged ears 4223 on the limit hinge 422 is one, see Fig.15, there are two hinged ears 4223 on the other limiting hinge 422, and they are arranged at intervals. The hinged ears 4223 on the two limiting hinges 422 in pairs are used to match each other. When assembling, the two limiting hinges 422 can be sleeved on the support rod 421, and the hinged ear 4223 on the limiting hinge 422 with only one hinged ear 4223 is located between the two hinged ears 4223 of the other limiting hinge 422. Of course, each limiting hinge 422 can have only one hinged ear 4223, and when assembling, the two types are arranged alternately.

[0085] Further, the restraining wall 4224 is located in the middle of the hinge body 4222, and the limiting portion 43 is arranged at one end of the hinge body 4222. Along the width direction of the hinge body 4222, the size of the limiting portion 43 is larger than the size of the restraining wall 4224. Figure 8 When the trigger device 423 is in the first position, the constraint wall 4224 cooperates with the trigger structure to make the pair of limit hinges 422 in a folded state, see Fig. 9 When the trigger device 423 is located at the second position, the trigger device 423 is separated from the constraint wall 4224, so that the pair of limiting hinges 422 are in an unfolded state under the action of the elastic member 4221, thereby cooperating with the limiting structure 14 on the roof panel to limit the roof panel.

[0086] In order to increase the strength of the restraining force between the limiting portion 43 and the limiting structure 14, the limiting portion 43 has a transversely extending limiting fold 431. The limiting fold 431 can increase the contact area between the limiting portion 43 and the limiting structure 14, so that the limiting portion 43 can better restrain the roof panel.

[0087] Furthermore, one possible implementation of the elastic member 4221 is a torsion spring, which is disposed between two adjacent hinged ears 4223. The torsion spring may be a torsion spring with an angle of 180°. When the trigger device 423 is located at the first position, the trigger device 423 cooperates with the constraint wall 4224 to make the limit hinge 422 in a folded state, and the torsion spring is compressed and deformed. When the trigger device 423 is located at the second position, the trigger device 423 is separated from the constraint wall 4224, and the torsion spring loses its constraint force, thereby restoring the deformation and driving the limit hinge 422 to unfold, so that the limit hinge 422 is engaged with the limit structure 14.

[0088] Combination Figure 8 Right now Fig. 9 , see Fig.16One possible implementation of the trigger device 423 is that the trigger device 423 includes a trigger main board, two supporting side boards 4232 and a positioning board 4233. The trigger main board is provided with a restraining groove 4234. The positioning board 4233 is elastic. The two supporting side boards 4232 are arranged at intervals, one end of which is respectively connected to the trigger main board, and the other end of which is respectively connected to the positioning board 4233. Figure 8 and Fig.10 When the positioning plate 4233 is in the first state, the trigger device 423 can be positioned at the first position, and the pair of limit hinges 422 can be constrained in the constraint groove 4234. Fig. 9 and Fig.11 When the trigger device 423 moves from the first position to the second position, the positioning plate 4233 is deformed, and the paired limiting hinges 422 are disengaged from the constraint grooves 4234. The positioning plate 4233 can be partially bonded to the boss 412, or can be connected to the boss 412 by screws. The positioning plate 4233 has a certain structural strength and also has a certain elasticity. When the positioning plate 4233 is in the first state, such as when the positioning plate 4233 is in a straight state, the trigger structure can be located in the first position. At this time, the constraint wall 4224 on the folded limiting hinge 422 can be constrained in the constraint groove 4234, so that the limiting hinge 422 remains in the folded state. When the trigger main board is subjected to a downward force, the positioning plate 4233 is bent by the force, so that the trigger device 423 as a whole moves downward relative to the boss 412. Here, the constraint groove 4234 moves downward relative to the constraint wall 4224 and gradually separates from the constraint wall 4224. When the constraint groove 4234 is completely separated from the constraint wall 4224, the constraint wall 4224 loses its restraining force, so that the limit hinge 422 can be unfolded under the drive of the elastic force of the elastic member 4221.

[0089] Furthermore, in order to facilitate the contact between the trigger main board and the limiting structure 14, one achievable method is that trigger ears 4235 are respectively provided on opposite ends of the trigger main board, the trigger ears 4235 extend away from the supporting side plate 4232, and a trigger slope 4236 is provided on the side of the trigger ear 4235 away from the supporting side plate 4232 and facing away from the base 41. The trigger ears 4235 can increase the relative length of the trigger main board so as to better connect with the limiting structure 14 on the roof panel. The trigger slope 4236 can increase the contact area between the trigger main board and the limiting structure 14, thereby reducing mutual damage between the two.

[0090] In order to ensure the rotation stability of the limit hinge 422, a protection groove 4237 is provided on the trigger main board, the protection groove 4237 is connected to the constraint groove 4234, and the limit hinge 422 is located in the protection groove 4237. By providing the protection groove 4237, the periphery of the limit fold 431 is protected, so that the limit device is prevented from being hindered by the roof panel, and the rotation of the limit hinge 422 is smoother and more stable.

[0091] The embodiment of the present invention is based on a roof panel that can be integrated with a photovoltaic component 30. The roof panel has a crest structure 11, and a limiting structure 14 is provided on the crest structure 11. A bracket with a trigger structure matching the roof panel is provided, namely a middle bracket 40. The middle bracket 40 can effectively restrain the roof panel at the position of the crest structure 11 of the roof panel, so that the roof panel equipped with the middle bracket 40 has better wind resistance and can also enable such metal roof panel system of the integrated photovoltaic system to have a wider range of use environments.

[0092] Among them, the middle bracket 40 is a combination of accessories such as a rotatable limit fold 431, an elastic member 4221, a trigger device 423 for constraining the limit fold 422, a support rod 421 and a base 41. During the installation process, the middle bracket 40 is triggered to switch from a folded state to an expanded state, thereby constraining the roof panel to achieve the purpose of wind resistance.

[0093] In the embodiment of the present invention, illustratively, one use of the stent is to combine Figure 8 and Fig. 9 , see Fig.10 and Fig.11 When the positioning plate 4233 is in a straight state, the trigger device 423 can be positioned at the first position, and the paired limit hinges 422 are constrained in the constraint grooves 4234, so that the limit hinges 422 remain in a folded state, thereby facilitating the crest structure 11 of the roof panel to be buckled on the bracket from top to bottom. The limiting structure 14 has a trigger surface 141 at the bottom and a limiting surface 142 at the top. When the roof panel continues to move downward, the trigger surface 141 contacts the constraint body 4231 and drives the constraint body 4231 to move downward, so that the trigger device 423 moves from the first position to the second position. The trigger main board drives the positioning plate 4233 to deform by supporting the side plate 4232. At the same time, the constraint groove 4234 moves downward relative to the constraint wall 4224 and gradually separates from the constraint wall 4224. When the constraint groove 4234 is completely separated from the constraint wall 4224, the constraint wall 4224 loses its binding force, so that the limiting hinge 422 can be unfolded under the drive of the elastic force of the elastic member 4221, and the constraint wall 4224 on the limiting hinge 422 cooperates with the limiting surface 142 to achieve limiting with the roof panel.

[0094] Based on the roof panels and roof components in the above embodiments, see Figure 5 Correspondingly, an embodiment of the present invention further provides a roof panel assembly, comprising: a roof panel and a bracket with a trigger structure as in the above embodiment, wherein the bracket with the trigger structure is the middle bracket 40 in the above embodiment.

[0095] See also Figure 1The roof panel includes: a main section 10 and a side section 20. The main section 10 is provided with a wave crest structure 11, the wave crest structure 11 has a first bearing surface 12 and a limiting space 13, and limiting structures 14 are respectively provided on both sides of the wave crest structure 11. Side sections 20 are respectively provided on opposite sides of the main section 10, and each side section 20 is respectively provided with a second bearing surface 21 and a locking structure 22.

[0096] The bracket with trigger structure, namely the middle bracket 40, see Fig.10 When the bracket is in the folded state, it can extend into the limited space 13. Fig.11 When the bracket is in the unfolded state, the limiting hinge 422 on the bracket is connected to the limiting structure 14, so that the roof panel is limitedly connected to the bracket.

[0097] Based on the roof panels and roof components in the above embodiments, see Figure 5 The embodiment of the present invention further provides a roofing system, comprising: a plurality of roofing panel assemblies as in the above embodiment, adjacent roofing panel assemblies are locked by a locking structure. The roofing panel assembly comprises a plurality of roofing panels and a plurality of middle brackets 40. Among them, the roofing panel is the roofing panel in the above embodiment, and the implementation method of the middle bracket 40 can refer to the content in the above embodiment, which will not be repeated here.

[0098] See also Figure 5 One possible implementation of the middle bracket 40 is that the middle bracket 40 includes a base 41 and a connector 42, the base 41 is used to be fixed on the roof purlin 60, and the connector 42 can be set in the limiting space 13 and connected to the limiting structure 14.

[0099] Furthermore, the roof system further includes a side bracket 50, which is connected to the locking structure 22 and is used to support the side segment 20. The side bracket 50 is used to define the position of the roof panel through the locking structure 22, and the side bracket 50 cooperates with the middle bracket 40 to define the position of the roof panel to improve the wind resistance.

[0100] Furthermore, the roof system also includes a photovoltaic module 30, which is arranged on the first bearing surface 12 and the second bearing surface 21 of the roof panel. One way to connect the photovoltaic module 30 to the roof panel is that the photovoltaic module 30 is bonded to the first bearing surface 12 and the second bearing surface 21 of the roof panel. For example, the photovoltaic module 30 can be bonded to the first bearing surface 12 and the second bearing surface 21 by means of an adhesive or tape, and this method has the effect of convenient operation. The adhesive can be a silicone structural adhesive or other materials, and the tape can be a pressure-sensitive adhesive or a tape of other materials.

[0101] Another way to connect the photovoltaic module 30 to the roof panel is to Figure 6, the photovoltaic component 30 can be fixed on the roof panel by a clamp assembly. One possible implementation of the clamp assembly is that the clamp assembly includes a middle clamp 70 assembly and a side clamp 71. The middle clamp 70 assembly is connected to the crest structure 11 on the roof panel, and forms a first clamping structure with the first bearing surface 12 to limit the photovoltaic component 30. The side clamp 71 is connected to the locking structure 22 on the roof panel, and forms a second clamping structure with the second bearing surface 21 to limit the photovoltaic component 30. Based on the clamping effect of the clamp assembly, the photovoltaic component 30 can be effectively fixed and the stability of the photovoltaic component 30 can be improved. Furthermore, the bonding method can be used in conjunction with the clamp assembly, that is, while the photovoltaic component 30 is bonded to the roof panel, the photovoltaic component 30 is fixed again by the clamp assembly, so that the position of the photovoltaic component 30 is more stable.

[0102] Furthermore, the roof system also includes a roof purlin 60, the middle bracket 40 is fixed to the roof purlin 60 through the base 41, and the side bracket 50 is also fixed to the roof purlin 60. The fixing method includes but is not limited to fixing by self-tapping screws, thereby achieving limiting restraint of the roof panel.
