[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them.

Therefore, features defined as "first" or "second" may explicitly or implicitly include at least one such feature.

[0038] 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 this specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0039] See also Figure 5 The retractable bracket 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 provided 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.

[0040] First, let me introduce the roof panels used with the bracket. Figure 1 FIG. 1 is a schematic side view of a roof panel according to an embodiment of the present invention. Figure 2 FIG. 1 is a schematic diagram of a three-dimensional structure of a roof panel according to an embodiment of the present invention. Figure 1 and Figure 2 shown.

[0041] An embodiment of the present invention provides a roof panel, comprising a main section 10 and side sections 20. The main section 10 is provided with a wave crest structure 11, which has a first bearing surface 12 and a limiting space 13. Limiting structures 14 are provided on either side of the wave crest structure 11. Side sections 20 are provided on opposite sides of the main section 10, each of which is 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 an adjacent roof panel.

[0042] The technical solution provided by the embodiment of the present invention is shown in Figure 3 and Figure 4The first bearing surface 12 on the crest structure 11 and the second bearing surface 21 on the side section 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 the corresponding support structure, which is the support provided in the embodiment of the present invention, and can also be called the middle support 40, to limit the roof panel to the roof purlin 60, so that the roof panel has good wind resistance.

[0043] In the embodiment of the present invention, the main body section 10 can be flat or non-flat, and can be shaped to suit different requirements. For example, if a flat surface is used, a raised or recessed reinforcement structure can be provided on the surface to increase rigidity and strength. The roof panels include, but are not limited to, sheet metal formed through processes such as stamping and rolling. The sheet metal may include a sheet with an anti-corrosion coating on its surface to improve its corrosion resistance. The sheet metal may include, but is not limited to, steel plate, and the anti-corrosion coating may include, but is not limited to, paint, galvanized, etc.

[0044] 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 bend it to form a Figure 1 Taking the center as an example, the side segments 20 are formed by bending upward relative to the main body segment 10. Then, taking the right side segment 20 as an example, the side segment 20 is further bent upward a predetermined distance to the right to form a second bearing surface 21. A bent segment 23 is formed on the second bearing surface 21 to form a drainage channel. The bent segment 23 is then bent upward to form a locking structure 22.

[0045] The crest structure 11 can be formed on the main section 10 through rolling or stamping. There can be one, two, or more crest structures 11. The crest structures 11, located away from the first bearing surface 12 of the main section 10, support the photovoltaic panels. Furthermore, the crest structures 11 further enhance the strength of the roof panel. Furthermore, multiple reinforcing ribs 15 are evenly arranged side by side on the main section 10 at locations other than the ridges. The ribs 15 bulge outward in the same direction as the crest structures 11.

[0046] See also Figure 5When the roof panel is assembled on the roof purlin 60 to form a roof system, the roof panel can also be used in conjunction with multiple support structures, such as the middle support 40 used in conjunction with the crest structure 11 and the side support 50 used in conjunction with the locking structure 22. The middle support 40 and the side support 50 are respectively fixed to the roof purlin 60 using self-tapping screws. At the same time, the middle support 40 is connected to the limiting structure 14 on the crest structure 11, and the side support 50 is connected to the locking structure 22. Thus, the middle support 40 and the side support 50 restrain the roof panel, improving the wind resistance of the roof panel.

[0047] 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.

[0048] Furthermore, in some feasible 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, which facilitates the buckling of the crest structure 11 on the roof panel onto the connector 42, or in other words, facilitates the insertion of the connector 42 into the limiting space 13. When the connector 42 is transformed 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.

[0049] Continue to see Figure 1 and Figure 2In order to facilitate the support of the photovoltaic module 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 the photovoltaic module 30 is installed, the two ends of the photovoltaic module 30 are respectively matched and abutted against the second bearing surfaces 21 on both sides, and the middle part of the photovoltaic module 30 is matched and supported on the first bearing surface 12, which can better support the photovoltaic module 30. When the supporting effect is good, the strength requirements of the photovoltaic module 30 itself can be reduced. As the strength requirements are reduced, the thickness of the photovoltaic module 30 itself can be reduced to reduce weight and manufacturing costs. Generally, the thickness of the photovoltaic module 30 itself can be reduced by reducing the thickness of the glass packaging plate on the front of the photovoltaic module 30. As the thickness of the glass packaging plate on the front is reduced, the light transmittance of the photovoltaic module 30 is enhanced, and the photoelectric conversion efficiency is also improved.

[0050] Furthermore, one method for connecting the photovoltaic module 30 to the roof panel is to adhere the photovoltaic module 30 to the first supporting surface 12 and the second supporting surface 21 of the roof panel. For example, the photovoltaic module 30 can be adhered to the first supporting surface 12 and the second supporting surface 21 using an adhesive or tape. This method is convenient to use. The adhesive can be a silicone structural adhesive or other materials, and the tape can be a pressure-sensitive adhesive or other tape.

[0051] Another way to connect the photovoltaic module 30 to the roof panel is to refer to Figure 6 , the photovoltaic component 30 can be fixed to 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 lock edge 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 is 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.

[0052] To further ensure the roof system's drainage function, one possible implementation is to provide a bent section 23 on the side section 20, located between the second bearing surface 21 and the locking structure 22. The bent section 23 curves downward relative to the second bearing surface 21, allowing rainwater falling on the roof system to flow away through the bent section 23, thereby ensuring the roof system's drainage function. 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, the gap between the main section 10 and the photovoltaic module 30 forms a heat dissipation channel, allowing air circulation to ensure the roof system's heat dissipation performance. Furthermore, 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 needs, for example, to be greater than 2 cm. This spacing ensures that the heat dissipation channel has a sufficient cross-sectional area to ensure sufficient air flow to dissipate heat from the photovoltaic module 30.

[0053] 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 the top plate is provided with a first bearing surface 12. The limiting structure 14 is a relief groove structure located on the side plates and recessed toward the limiting space 13. In this arrangement, the relief groove structures on the two side plates extend in opposite directions, or in other words, the relief groove structures extend toward the limiting space 13 enclosed by the two side plates. The relief 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.

[0054] Furthermore, in order to achieve a better limiting effect between the limiting avoidance groove and the connector, continue to refer to Figure 1 and Figure 2 The avoidance groove structure extends horizontally or gradually tilts toward the plane of the roof panel. In this arrangement, the avoidance groove structure can better engage with the connector 42 on the middle bracket 40, and it is easier for them to exert force on each other. When the roof panel tends to move upward in windy conditions, the avoidance groove structure and the connector 42 are more conducive to exerting a downward force on the roof panel, thereby better preventing the roof panel from moving upward.

[0055] 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 ribs 15 can be formed on the main section 10 by rolling or stamping processes. 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 uneven. 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.

[0056] In the embodiment of the present invention, a construction method of the roof panel is as follows: For the convenience of description, 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.

[0057] During construction, first, multiple support structures are spaced apart along the length direction of the roof panel and fixed to the roof purlin 60. The fixing method includes but is not limited to fixing by self-tapping screws. The 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 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 made by taking one limit space 13 corresponding to one support structure as an example, which does not constitute an improper limitation of the embodiment of the present invention.

[0058] 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 crest 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.

[0059] After assembly, the opposing locking structures 22 on two adjacent roof panels can be locked together. After the roof panels are assembled, the connector 42 on the center bracket 40 is located within the limiting space 13. The limiting space 13 provides the roof panels with a wind-resistant limiting structure 14, which is connected to the center bracket 40. In windy conditions, if the roof panels are prone to "lifting," the limiting structure 14 cooperates with the center bracket 40, and the side brackets 50 cooperate with the locking structure 22 to jointly resist the "lifting," ensuring that the roof panels remain stable, thereby significantly improving the wind resistance of the roof panels and the roof system they form.

[0060] Furthermore, after adjacent roof panels are assembled, the locking edge structure 22 on one side of the roof panel can be locked with the locking edge structure 22 on the other side of the adjacent roof panel. The locking method includes, but is not limited to, wrapping one locking edge structure 22 around another locking edge structure 22 and bending it inward to create a full-length, seamless locking seam, ensuring a good waterproofing effect. Of course, the degree of bending of the locking seam can also be increased to achieve better waterproofing performance. Both sides of the roof panel adopt a 360-degree (or more) seamless locking seam waterproofing method, and a limiting structure 14 is provided to provide a wind-resistant curved bearing surface, using a support structure for wind resistance.

[0061] In the embodiment of the present invention, there are many ways to implement the support structure, one of which is to refer to Figure 7 One implementation of the support structure in the embodiment of the present invention is that the support structure is an openable support, including: a support seat 46, at least a pair of limit folding plates 47 and a transfer shaft 49. Figure 8 The support base 46 includes a base plate 461 and a support plate 462 disposed on the base plate 461. The support plate 462 is provided with an escape groove 463. The opposite ends of the escape groove 463 are respectively provided with a first sleeve 464. Figures 9 to 11 At least one second sleeve 471 is provided on the limiting flap 47. The pair of limiting flaps 47 are positioned on opposite sides of the support plate 462, with an elastic member extending through the relief groove 463 disposed between the limiting flaps 47. The support base 46 is the base 41, and the limiting flap 47 is the connector 42 connected to the limiting structure 14. The adapter shaft 49 is respectively engaged with the first sleeve 464 and the second sleeve 471, allowing the limiting flap 47 to rotate relative to the base plate 461.

[0062] See also Figure 7 When the retractable bracket is not connected to the roof panel, the paired limit folding edges are in an unfolded state under the elastic force of the elastic member. Figure 12The limiting structure 14 has a trigger surface 141 at the bottom and a limiting surface 142 at the top. When the roof panel is buckled on the bracket from top to bottom through the crest structure 11, the roof panel will move downward, and the roof panel will first contact the limiting folding plate 47 through the triggering surface 141. The sum of the unfolded lengths of the paired limiting folding plates 47 is greater than the distance between the triggering surfaces 141 on both sides, so that the triggering surfaces 141 on both sides will squeeze the limiting folding plates 47. The squeezed limiting folding plates 47 will rotate downward, so that the paired limiting folding plates 47 gradually change from the unfolded state to the folded state, so as to facilitate the limiting folding plates 47 to cross the triggering surfaces 141 and enter the limiting space 13.

[0063] See also Figure 13 When the limiting folding plate 47 passes over the limiting structure 14, the limiting folding plate 47 is separated from the limiting structure 14, and the limiting folding plate 47 loses its restraining force, so that the limiting folding plate 47 can be unfolded under the elastic force of the elastic member. The limiting folding plate 47 cooperates with the limiting surface 142 on the limiting structure 14 to limit the roof panel to the roof purlin 60, so that the roof panel has good wind resistance, and the limiting folding plate 47 on the bracket can be in two states to facilitate installation with the roof panel.

[0064] Continue to see Figure 7 One possible implementation of the support seat 46 is that the base plate 461 and the support plate 462 form a T-shaped structure, and the first sleeve 464 is arranged at the end of the support plate 462 away from the base plate 461. The inner diameter and outer diameter of the first sleeve 464 are consistent with the inner diameter and outer diameter of the second sleeve 471. The lower edge of the first sleeve 464 is slightly higher than the upper edge of the support plate 462 to avoid the situation where the second sleeve 471 cannot be assembled due to errors in the processing. The adapter shaft 49 can pass through the first sleeve 464 and the second sleeve 471, thereby integrating the support seat 46 and the limiting folding plate 47 together. The limiting folding plate 47 can rotate around the adapter shaft 49 to achieve the conversion between the folded state and the unfolded state. Furthermore, in order to facilitate the installation of the base plate 461 and the roof purlin 60, a fixing hole is provided on the base plate 461, and a mounting screw is provided in the fixing hole. By pre-setting fixing holes on the base plate 461, it is convenient to connect the mounting screws, and the base plate 461 can be fixed to the roof purlin 60 by the mounting screws. Furthermore, to enhance the strength of the support base 46, a reinforcement plate is provided between the base plate 461 and the support plate 462. The reinforcement plate is obliquely connected to the base plate 461 and the support plate 462 to improve the structural strength of the support base 46, thereby improving the wind resistance of the roof panel.

[0065] See also Figure 7 and Figure 9In some feasible embodiments of the present invention, one possible implementation of the limiting flap 47 is as follows: the limiting flap 47 includes a flap body and a connecting arm 474 disposed on the flap body, a second sleeve 471 disposed on the flap body, and an elastic member connected to the connecting arm 474. The flap body is used to connect to the limiting structure 14, and the flap body is connected to the adapter shaft 49 via the second sleeve 471. The connecting arm 474 is used to connect to the elastic member, and the elastic member passes through the avoidance groove 463 and is respectively connected to the connecting arm 474 of the pair of limiting flaps 47.

[0066] Furthermore, to better connect the folding plate body to the limiting structure 14, one possible implementation method is that the folding plate body includes a straight section 472 and an inclined section 473, the second sleeve 471 is disposed at the end of the straight section 472 away from the inclined section 473, and the connecting arm 474 is disposed on the straight section 472 or at the connection between the straight section 472 and the inclined section 473. One implementation method of the limiting structure 14 is that the limiting structure 14 is a relief groove structure, which extends horizontally or gradually tilts toward the plane of the top plate. The shape of the folding plate body matches the shape of the upper edge of the relief groove structure. For example, when the relief groove structure extends horizontally, the folding plate body can also extend horizontally. When the relief groove structure is tilted, the folding plate body includes a straight section 472 and an inclined section 473, and the inclined section 473 better engages with the upper edge of the relief groove structure, making it easier to apply force to each other.

[0067] Furthermore, one possible implementation of the elastic member is that the elastic member is a pressure spring, and the pressure spring is disposed between two adjacent connecting arms 474. Figure 7 When the bracket is not connected to the roof panel, the paired limit folding edges are in an unfolded state under the tension of the elastic member. Figure 12 The trigger surface 141 of the limiting structure 14 will squeeze the limiting folding plate 47, and the squeezed limiting folding plate 47 will rotate downward, so that the pair of limiting folding plates 47 gradually change from the expanded state to the collapsed state, and the pressure spring is deformed by the force. Figure 13 When the limiting folding plate 47 passes over the limiting structure 14, the limiting folding plate 47 is separated from the limiting structure 14, the limiting folding plate 47 loses its restraining force, and the pressure spring recovers its deformation, so that the limiting folding plate 47 can be unfolded under the elastic force of the elastic part.

[0068] One way to connect the elastic member to the connecting arm 474 is to provide a through hole 475 on the connecting arm 474, and to hook the end of the pressure spring into the through hole 475. The connecting arm 474 is connected to the pressure spring via the through hole 475, which has a simple structure, convenient connection, and easy operation, while also effectively reducing costs.

[0069] Furthermore, in order to make the limiting effect of the limiting folding plate 47 on the roof panel more stable, Figure 7 and Figure 9 , see Figure 10 and Figure 11 , a limiting portion 476 is provided on the second sleeve 471. When the limiting folding plate 47 is in the expanded state, the limiting portions 476 of the paired limiting folding plates 47 abut against each other, thereby limiting the limiting folding plates 47 from continuing to rotate in the direction away from the base plate 461. The limiting portions 476 provided make the paired limiting folding plates 47 remain in the expanded state when they are in the expanded state. For example, the paired limiting folding plates 47 are approximately 180 degrees when expanded. Based on the limiting effect of the elastic member and the limiting portion 476, when the limiting folding plate 47 is in the expanded state, the limiting folding plate remains expanded at 180 degrees, ensuring that the limiting structure 14 of the roof panel will not be decoupled from the limiting folding plate 47 under the action of wind suction, thereby playing a role in resisting wind-lifting.

[0070] Furthermore, to enhance the retaining strength of the retaining portion 476, the retaining portion 476 extends onto the main body of the folding plate. When the retaining portions 476 of the paired retaining flaps 47 abut against each other, the abutting force of the retaining portions 476 can be transmitted to the main body of the folding plate, which then shares the abutting force with the main body of the folding plate, thereby enhancing the retaining strength of the retaining portion 476 and enabling the retaining flaps 47 to be better maintained in the expanded state.

[0071] Combine Figure 9 , see Figure 10 and Figure 11 In this embodiment of the present invention, the paired limiting flaps 47 are implemented in substantially the same manner, differing only in that they are flipped and mirror-symmetrical. To ensure a stable connection between the paired limiting flaps 47 and the adapter shaft 49, multiple second sleeves 471 are provided on the limiting flaps, each of which is spaced apart on the flap body.

[0072] The embodiment of the present invention is based on a roof panel that can be integrated with a photovoltaic module 30. The roof panel has a crest structure 11, and a limiting structure 14 is provided on the crest structure 11. A bracket 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 systems of integrated photovoltaic systems to have a wider range of usage environments.

[0073] Among them, the middle bracket 40 is composed of accessories such as a rotatable limiting folding plate 47, an elastic member and a support seat 46. During the installation process, the middle bracket 40 is converted from a folded state to an expanded state, thereby constraining the roof panel and achieving the purpose of wind resistance.

[0074] In the embodiment of the present invention, illustratively, one way to use the bracket is to see Figure 7When the bracket is not connected to the roof panel, the paired limit folding edges are in an unfolded state under the elastic force of the elastic member. Figure 12 The limiting structure 14 has a trigger surface 141 at the bottom and a limiting surface 142 at the top. When the roof panel is buckled on the bracket from top to bottom through the crest structure 11, the roof panel will move downward, and the roof panel will first contact the limiting folding plate 47 through the triggering surface 141. The sum of the unfolded lengths of the paired limiting folding plates 47 is greater than the distance between the triggering surfaces 141 on both sides, so that the triggering surfaces 141 on both sides will squeeze the limiting folding plates 47. The squeezed limiting folding plates 47 will rotate downward, so that the paired limiting folding plates 47 gradually change from the unfolded state to the folded state, so as to facilitate the limiting folding plates 47 to cross the triggering surfaces 141 and enter the limiting space 13.

[0075] See also Figure 13 When the limiting folding plate 47 passes over the limiting structure 14, the limiting folding plate 47 is separated from the limiting structure 14, and the limiting folding plate 47 loses its restraining force, so that the limiting folding plate 47 can be unfolded under the elastic force of the elastic member. The limiting folding plate 47 cooperates with the limiting surface 142 on the limiting structure 14 to limit the roof panel to the roof purlin 60, so that the roof panel has good wind resistance, and the limiting folding plate 47 on the bracket can be in two states to facilitate installation with the roof panel.

[0076] Based on the roof panels and roof components in the above embodiments, see Figure 5 Accordingly, an embodiment of the present invention further provides a roof panel assembly, comprising: a roof panel and a bracket as in the above embodiment, wherein the bracket is the middle bracket 40 in the above embodiment.

[0077] See also Figure 1 and Figure 2 The roof panel includes a main section 10 and side sections 20. The main section 10 is provided with a crest structure 11, which has a first bearing surface 12 and a limiting space 13. Limiting structures 14 are provided on either side of the crest structure 11. Side sections 20 are provided on opposite sides of the main section 10, each of which is provided with a second bearing surface 21 and a locking structure 22.

[0078] The bracket is the middle bracket 40, see Figure 12 and Figure 13 When the bracket is in the folded state, it can be extended into the limited space 13. Figure 11 When the bracket is in the expanded state, the limiting folding plate 47 on the bracket is connected to the limiting structure 14, so that the roof panel is connected to the bracket in a limiting manner.

[0079] Based on the roof panels and roof components in the above embodiments, see Figure 6The present invention also provides a roofing system comprising: a plurality of roof panel assemblies as described in the above-mentioned embodiments, with adjacent roof panel assemblies locked together by a locking edge structure 22. The roof panel assembly includes a plurality of roof panels and a plurality of intermediate brackets 40. The roof panels are those described in the above-mentioned embodiments, and the implementation of the intermediate brackets 40 can be found in the description of the brackets in the above-mentioned embodiments and will not be further described here.

[0080] See also Figure 5 One possible implementation of the middle bracket 40 is that the middle bracket 40 includes a base 41 and a connecting head 42. The base 41 is used to be fixed on the roof purlin 60. The connecting head 42 can be set in the limiting space 13 and is limitedly connected to the limiting structure 14.

[0081] Furthermore, the roof system includes side supports 50, which are connected to the locking structure 22 and are used to support the side segments 20. The side supports 50 are used to define the position of the roof panel through the locking structure 22. The side supports 50 cooperate with the center support 40 to define the position of the roof panel to improve wind resistance.

[0082] Furthermore, the roofing system includes a photovoltaic module 30, which is disposed on the first and second bearing surfaces 12, 21 of the roof panel. One method of connecting the photovoltaic module 30 to the roof panel is to bond the photovoltaic module 30 to the first and second bearing surfaces 12, 21 of the roof panel. For example, the photovoltaic module 30 can be bonded to the first and second bearing surfaces 12, 21 of the roof panel using an adhesive or tape. This method is convenient for operation. The adhesive can be silicone structural adhesive or other materials, and the tape can be pressure-sensitive adhesive or other tape.

[0083] Another way to connect the photovoltaic module 30 to the roof panel is to refer to Figure 6 , the photovoltaic component 30 can be fixed to 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 lock edge 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 is 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.

[0084] 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.
