Description

Technical Field

[0001] This application relates to the field of photovoltaic technology, and in particular to photovoltaic systems. Background Technology

[0002] Photovoltaic power generation is a device that converts solar energy into electrical energy based on the photoelectric effect. Building photovoltaics (BPV) can be integrated into buildings by installing photovoltaic devices on the exterior walls of buildings. As a key solution for the integration of buildings and energy, BPV technology has seen accelerated development in recent years driven by policy initiatives.

[0003] In related technologies, photovoltaic systems consist of multiple photovoltaic modules stacked sequentially. When subjected to external forces such as wind pressure, the stacked photovoltaic modules may shift, reducing structural strength and posing risks such as leakage or loosening. Utility Model Content

[0004] Therefore, it is necessary to provide a photovoltaic system that addresses the problem that photovoltaic modules are prone to sliding when subjected to external forces such as wind pressure, causing the first end to detach from the mounting cavity.

[0005] A photovoltaic system, comprising:

[0006] At least two mounting supports are provided at intervals along the installation direction, and each mounting support has a mounting cavity and a snap-fit ​​cavity.

[0007] At least one photovoltaic module, the photovoltaic module having a first end and a second end;

[0008] Along the installation direction, the mounting cavity of the upper one of two adjacent mounting supports is used to accommodate the first end of the photovoltaic module, the second end of the photovoltaic module can be snapped into the snap-fit ​​cavity of the lower one along the first direction to the left, and the second end can move to the right along the first direction to separate from the snap-fit ​​cavity;

[0009] The first limiting element is located in the mounting cavity;

[0010] A second limiting member is disposed on the first end, and the first limiting member and the second limiting member are engaged to constrain the first end to reciprocate along the first direction.

[0011] This photovoltaic system prevents the first end from sliding within the mounting cavity, thus avoiding detachment and improving the stability of the photovoltaic module after installation. Simultaneously, the first and second limiting members prevent the first end from moving to the left along the first direction within the mounting cavity, thereby avoiding the outer wall of the mounting cavity bearing the main weight of the photovoltaic module, reducing the stress on the mounting cavity, and further improving structural stability.

[0012] In one embodiment, the first limiting member is located on the upper surface of the mounting cavity facing the first end along the second direction, and the second limiting member is located on the lower surface of the first end along the second direction, with the first limiting member and the second limiting member disposed opposite to each other.

[0013] In this embodiment, when the first limiting member and the second limiting member are engaged, gravity can be used to increase the engagement effect between the first limiting member and the second limiting member at the first end, thereby improving the stability of the photovoltaic module installation structure.

[0014] In one embodiment, along the first direction, there are multiple first limiting members and multiple second limiting members, and the multiple first limiting members and multiple second limiting members are connected in a multi-level snap-fit ​​manner.

[0015] This embodiment helps to increase the stability of the snap-fit, thereby increasing the resistance to sliding of the first end in the mounting cavity.

[0016] In one embodiment, a plurality of first limiting members and a plurality of second limiting members are arranged opposite to and staggered.

[0017] The operator only needs to lower the first end to achieve the snap-fit ​​engagement of the first and second limiting components, which facilitates rapid positioning and improves assembly efficiency. Furthermore, the first and second limiting components have strong structural tolerance, low requirements for machining and assembly errors, and a simple structure, which helps reduce costs and losses.

[0018] In one embodiment, the first limiting member and the second limiting member are toothed, a plurality of the first limiting members are arranged sequentially along the first direction, a plurality of the second limiting members are arranged sequentially along the first direction, and the first limiting member and the second limiting member are engaged.

[0019] This snap-fit ​​structure utilizes a toothed meshing mechanism, which facilitates multi-level precise positioning and is applicable to various relative positions between the mounting bracket and the first end, thus making it suitable for photovoltaic modules of different sizes. Simultaneously, the toothed meshing surfaces ensure sufficient contact and strong resistance to displacement, improving resistance to vibration, impact, and other external forces, and preventing loosening at the snap-fit ​​joint.

[0020] In one embodiment, the first limiting member and the second limiting member are bosses, a plurality of first limiting members are arranged at intervals along the first direction, a plurality of second limiting members are arranged at intervals along the first direction, the interval between the first limiting member and two adjacent second limiting members corresponds to the interval between the second limiting member and two adjacent first limiting members.

[0021] The boss structure is simple, with low machining and assembly costs. Furthermore, the corresponding fit between the boss and the spacer allows for certain machining deviations, which helps improve the tolerance rate of machining errors in the first and second limiting components, thus reducing machining costs. Simultaneously, the first and second limiting components of this boss structure improve the dual-sided limiting stability in both the left and right directions of the first direction, enhancing resistance to displacement.

[0022] In one embodiment, the boss has a square cross-sectional shape, or the outline of the boss's cross-section is arc-shaped.

[0023] The square cross-section of the boss enhances the stability of the double-sided positioning in both the left and right directions, improving its resistance to displacement. The arc-shaped profile of the boss's cross-section reduces assembly resistance; when the first and second positioning components are not properly assembled, the arc-shaped surface can drive the first end to slide into position, providing a guiding function. Simultaneously, the arc-shaped surface of the boss helps avoid stress concentration, reduces wear during assembly, and ultimately extends the lifespan of both the mounting bracket and the photovoltaic module.

[0024] In one embodiment, the number of the first limiting members is not less than the number of the second limiting members.

[0025] This embodiment helps to increase the length of the first limiting member used to limit the second limiting member, making it easier for the second limiting member to engage with the first limiting member, reducing the constraints on the position of the photovoltaic module during the assembly process, and increasing the fault tolerance of the assembly process.

[0026] In one embodiment, the mounting bracket includes:

[0027] A first support plate, wherein the first support plate is provided with the first limiting member;

[0028] The first connecting plate is connected to the first support plate;

[0029] The second support plate is connected to the end of the first connecting plate away from the first support plate, and the first support plate, the first connecting plate and the second support plate together form the mounting cavity;

[0030] The second connecting plate is connected to the second support plate;

[0031] A snap-fit ​​plate is connected to the end of the second connecting plate away from the second support plate, and the snap-fit ​​plate, the second connecting plate, and the second support plate together form the snap-fit ​​cavity.

[0032] In one embodiment, the height of the first limiting member is 1 / 3 to 2 / 3 of the sum of the height of the first limiting member and the thickness of the first support plate, to ensure the limiting function and prevent jamming failure. Simultaneously, this height setting of the first limiting member helps protect the first support plate, preventing structural damage, balancing material forces, and optimizing cost and weight. The 1 / 3 to 2 / 3 ratio minimizes the total material usage while meeting the limiting and support requirements, balancing lightweight design and cost control.

[0033] In one embodiment, the first support plate extends along the first direction, such that the surface of the first end opposite to the first support plate is arranged parallel to the first support plate.

[0034] This embodiment helps to ensure that the first limiting member set along the first direction can fully cooperate with each of the second limiting members, avoiding possible offset or separation, and improving the effectiveness and stability of the snap-fit ​​structure.

[0035] In one embodiment, the second support plate includes:

[0036] The limiting part is formed by maintaining a preset distance between the connection point of the second connecting plate and the second support plate and the end of the second support plate away from the first connecting plate.

[0037] This embodiment helps to ensure that the mounting cavity has sufficient limiting depth, preventing the first end from moving out of the mounting cavity in the second direction.

[0038] In one embodiment, the photovoltaic system further includes:

[0039] A reset member is disposed in the mounting cavity, and the two ends of the reset member abut against the first end and the first connecting plate of the mounting support, respectively. The reset member is configured such that the first end provides an abutment force to the left along the first direction.

[0040] The reset component helps to further increase the resistance to the first end moving to the right along the first direction, which helps to further improve the stability of the photovoltaic module installation structure. Attached Figure Description

[0059] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0060] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0061] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0062] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0063] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0064] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0065] See Figures 1 to 2 , Figure 1 A schematic diagram of the structure of a photovoltaic system provided in one embodiment of this application is shown. Figure 1 . Figure 2 A schematic diagram of the structure of a photovoltaic system provided in one embodiment of this application is shown. Figure 2 .

[0066] This embodiment provides a photovoltaic system including at least two mounting supports 100 and at least one photovoltaic module 200. The at least two mounting supports 100 are spaced apart along an installation direction, specifically, the installation direction is a downward-sloping direction at a certain angle. Each mounting support 100 has a mounting cavity 110 and a snap-fit ​​cavity 120. The photovoltaic module 200 has a first end 210 and a second end 220. Along the installation direction, the mounting cavity 110 of the upper mounting support 100 accommodates the first end 210 of the photovoltaic module 200. The second end 220 of the photovoltaic module 200 can snap into the snap-fit ​​cavity 120 of the lower mounting support 100 along a first direction to the left, and the second end 220 can move to the right along the first direction to separate from the snap-fit ​​cavity 120, thereby fixing the photovoltaic module 200 using the mounting supports 100. The first direction is horizontal, and the photovoltaic module 200 uses its first end 210 and second end 220 to cooperate with the mounting supports 100 to maintain its horizontal orientation.

[0067] In use, this photovoltaic system can be installed on a roof with a certain slope or on a hillside with a certain slope. The photovoltaic system also includes fasteners, which, exemplarily, can be purlins. Multiple fasteners are arranged parallel to each other and spaced apart along the installation direction, and the mounting bracket 100 is fixed to the fasteners. Since the first end 210 and the second end 220 of the photovoltaic module 200 respectively mate with the mounting cavity 110 and the snap-fit ​​cavity 120 of two adjacent mounting brackets 100, the opening directions of the mounting cavity 110 and the snap-fit ​​cavity 120 are opposite to each other. During installation, the mounting cavity 110 opens downwards, and the snap-fit ​​cavity 120 opens upwards. When assembling the photovoltaic module 200, the first end 210 is accommodated in the mounting cavity 110 of the upper mounting bracket 100, and the second end 220 snaps into the snap-fit ​​cavity 120 of the lower mounting bracket 100. The entire installation and connection process of this photovoltaic system is simple, easy to operate, and helps reduce installation costs.

[0068] At this time, due to the certain tilt angle of the installation direction, the separation of the photovoltaic module 200 by its own gravity can make its connection with the snap-fit ​​cavity 120 of the mounting bracket 100 more stable. The mounting bracket 100 located below has a supporting and fixing function, while the mounting cavity 110 located above mainly plays a supporting role.

[0069] For example, the first end 210 of the photovoltaic module 200 is a first frame, and the second end 220 is a second frame 221 and a hook 222 for fixing the photovoltaic panel 240. The second frame 221 is connected to the photovoltaic panel 240, and the hook 222 is connected to the second frame 221 and supports the photovoltaic panel 240 from below. During assembly, the hook 222 is inserted into the snap-fit ​​cavity 120 from the opening on the right side and snaps into the snap-fit ​​cavity 120, thereby realizing assembly.

[0070] like Figures 1 to 4 As shown, in one embodiment, the photovoltaic system further includes a first limiting member 130 and a second limiting member 230. The first limiting member 130 is disposed in the mounting cavity 110, and the second limiting member 230 is disposed on the first end 210. The first limiting member 130 and the second limiting member 230 are engaged to constrain the reciprocating movement of the first end 210 along a first direction, thereby preventing the first end 210 from sliding in the mounting cavity 110 and causing it to detach from the mounting cavity 110, which helps to improve the stability of the photovoltaic module 200 after installation. At the same time, by preventing the first end 210 from moving to the left in the mounting cavity 110 along the first direction, the first limiting member 130 and the second limiting member 230 avoid the outer wall of the engaging cavity 120 bearing the main weight of the photovoltaic module 200, thereby reducing the stress on the engaging cavity 120 and improving structural stability.

[0071] See now Figures 5 to 8 The assembly process of photovoltaic module 200 is explained.

[0072] When assembling photovoltaic modules 200, firstly, as Figure 5 As shown, insert the first end 210 of the photovoltaic module 200 into the mounting cavity 110, and then... Figure 6 As shown, lower one side of the second end 220 downwards along the second direction. Here, the second direction refers to the vertical direction. For example... Figure 7 As shown, keep the first end 210 in the raised state to prevent the first limiting member 130 from contacting the second limiting member 230. Pull the photovoltaic module 200 as a whole to the left along the first direction to make the second end 220 engage with the snap-fit ​​cavity 120. Finally, as shown... Figure 8 As shown, one side of the first end 210 is lowered, causing the first limiting member 130 and the second limiting member 230 to engage, thus completing the assembly of the photovoltaic module 200. At this time, the first limiting member 130 and the second limiting member 230 can restrain the sliding of the first end 210, thereby improving the wind resistance of the photovoltaic module 200 and enhancing its structural stability.

[0073] See now Figures 9 to 12 The assembly process of photovoltaic module 200 is explained.

[0074] like Figure 9 As shown, when disassembling the photovoltaic module 200, first lift one side of the first end 210 to disengage the first limiting member 130 and the second limiting member 230 from their latching. Then proceed as follows: Figure 10 As shown, the photovoltaic module 200 is pushed to the right along the first direction, causing the second end 220 to disengage from the snap-fit ​​cavity 120. For example... Figure 11 As shown, the first end 210 is held in a raised state, then the second end 220 is raised upwards, and finally... Figure 12 As shown, pull the photovoltaic module 200 to the left to remove the first end 210 from the mounting cavity 110, thus completing the disassembly of the photovoltaic module 200.

[0075] The assembly and disassembly of the photovoltaic modules 200 in this photovoltaic system do not require external tools, and the operation is simple and quick.

[0076] The engagement function of the first limiting member 130 and the second limiting member 230 is further analyzed based on the above installation and disassembly process. When the photovoltaic module 200 is subjected to external forces such as wind pressure, the photovoltaic module 200 is prone to sliding left and right, making it easy for the first end 210 to move to the right in the first direction within the mounting cavity 110. When the first limiting member 130 is not provided in the mounting cavity 110, the first end 210 moves to the right without resistance, which would cause the second end 220 to disengage from the engaging cavity 120, allowing the photovoltaic module 200 to fall off. However, the first limiting member 130 and the second limiting member 230 can constrain the reciprocating movement of the first end 210 in the first direction, thereby preventing the first end 210 from moving to the right, preventing the second end 220 from disengaging from the engaging cavity 120, and thus preventing the photovoltaic module 200 from falling off.

[0077] In the photovoltaic system, another set of photovoltaic modules 200 located above can be snapped into the snap-fit ​​cavity 120 of the upper mounting bracket 100. The mounting cavity 110 of the lower mounting bracket 100 can be used to install another set of photovoltaic modules 200 located below. Each photovoltaic module 200 can be arranged sequentially along a first direction, and the positions where two adjacent photovoltaic modules 200 are connected to the same mounting bracket 100 can overlap in projection. Of course, they can also not overlap in projection.

[0078] In one embodiment, the first limiting member 130 is located on the upper surface 141 of the mounting cavity 110 facing the first end 210 along the second direction, and the second limiting member 230 is located on the lower surface of the first end 210 along the second direction. The first limiting member 130 and the second limiting member 230 are arranged opposite to each other, so that when the first limiting member 130 and the second limiting member 230 are engaged, the engagement effect of the first limiting member 130 and the second limiting member 230 of the first end 210 can be increased by gravity, thereby improving the stability of the photovoltaic module 200 mounting structure.

[0079] In one embodiment, the first limiting member 130 and the second limiting member 230 can be a slot and a hook. The slot and hook can be provided on either side of the mounting cavity 110, and when the first end 210 is inserted into the mounting cavity 110, the slot and hook are engaged to achieve the desired result.

[0080] In one embodiment, along the first direction, there are multiple first limiting members 130 and multiple second limiting members 230. The multiple first limiting members 130 and multiple second limiting members 230 are connected in a multi-level snap-fit ​​manner, thereby increasing the stability of the snap-fit ​​and increasing the resistance of the first end 210 sliding in the mounting cavity 110.

[0081] Furthermore, the multiple first limiting members 130 and multiple second limiting members 230 are arranged opposite to each other and staggered. The operator only needs to lower the first end 210 to achieve the snap-fit ​​engagement of the first limiting members 130 and the second limiting members 230, which is conducive to rapid positioning and improves assembly efficiency. Moreover, the first limiting members 130 and the second limiting members 230 have strong structural tolerance, low requirements for processing and assembly errors, and simple structure, which helps to reduce costs and losses.

[0082] In one embodiment, the first limiting member 130 and the second limiting member 230 are toothed. Multiple first limiting members 130 are sequentially arranged along a first direction, and multiple second limiting members 230 are sequentially arranged along the first direction, with the first limiting members 130 and the second limiting members 230 engaging. This snap-fit ​​structure utilizes the relative engagement of the toothed structure, which facilitates multi-level precise positioning and is applicable to various relative positions between the mounting bracket 100 and the first end 210, thus making it suitable for photovoltaic modules 200 of different sizes. Simultaneously, the toothed structure provides sufficient contact at the meshing surfaces, exhibiting strong resistance to displacement, which improves resistance to vibration, impact, and other external forces, preventing loosening at the snap-fit ​​joint.

[0083] like Figure 13 As shown, in another embodiment, the first limiting member 130 and the second limiting member 230 are bosses. Multiple first limiting members 130 are sequentially spaced along a first direction, and multiple second limiting members 230 are sequentially spaced along the first direction. The spacing between a first limiting member 130 and two adjacent second limiting members 230 corresponds to the spacing between two adjacent first limiting members 130. The boss structure is simple, with low processing and assembly costs. Furthermore, the corresponding fit between the boss and the spacing allows for certain deviations in processing, which helps improve the tolerance rate of processing errors for the first limiting members 130 and the second limiting members 230, and reduces processing costs. Simultaneously, this boss structure for the first limiting members 130 and the second limiting members 230 helps improve the bilateral limiting stability in both the left and right directions of the first direction, enhancing the resistance to displacement.

[0084] Furthermore, such as Figure 13 As shown, the cross-sectional shape of the boss is square, which helps to further improve the stability of the double-sided limiting in the first direction and the left and right directions, and improve the resistance to displacement.

[0085] like Figure 14 As shown, the profile of the boss's cross-section is arc-shaped, which helps reduce assembly resistance. When the first limiting member 130 and the second limiting member 230 are not assembled into their positions, the arc-shaped surface can drive the first end 210 to slide into place, providing a certain guiding effect. At the same time, the arc-shaped surface of the boss helps avoid stress concentration, reduces wear on the mating parts, and helps improve the service life of the mounting bracket 100 and the photovoltaic module 200.

[0086] The number of first limiting members 130 is not less than the number of second limiting members 230, thereby increasing the length of the first limiting member 130 used to limit the second limiting member 230, making it easier for the second limiting member 230 to engage with the first limiting member 130 for limiting, reducing the constraints on the position of the photovoltaic module 200 during the assembly process, and increasing the fault tolerance of the assembly process.

[0087] like Figure 3 As shown, in one embodiment, the mounting bracket 100 includes a first support plate 140, a first connecting plate 150, a second support plate 160, a second connecting plate 170, and a third support plate. The first support plate 140 is provided with a first limiting member 130. The first connecting plate 150 is connected to the first support plate 140. The second support plate 160 is connected to the end of the first connecting plate 150 away from the first support plate 140. The first support plate 140, the first connecting plate 150, and the second support plate 160 together form a mounting cavity 110. The second connecting plate 170 is connected to the second connecting plate 170. A snap-fit ​​plate 180 is connected to the end of the second connecting plate 170 away from the second support plate 160. The snap-fit ​​plate 180, the second connecting plate 170, and the second support plate 160 together form a snap-fit ​​cavity 120, thus forming the structure of the mounting cavity 110 and the snap-fit ​​cavity 120.

[0088] Optionally, the height of the first limiting member 130 is 1 / 3 to 2 / 3 of the sum of the height of the first limiting member 130 and the thickness of the first support plate 140, to ensure the limiting function and prevent snap-fit ​​failure. At the same time, this height setting of the first limiting member 130 helps protect the first support plate 140, preventing structural damage, balancing material forces, and optimizing cost and weight. The 1 / 3 to 2 / 3 ratio minimizes the total material usage while meeting the limiting and support requirements, balancing lightweight design and cost control.

[0089] The first support plate 140 extends along the first direction, so that the surface of the first end 210 opposite to the first support plate 140 is set parallel to the first support plate 140, so as to ensure that the first limiting member 130 set along the first direction can fully cooperate with each second limiting member 230, avoid the connection offset or separation, and help improve the effectiveness and stability of the snap-fit ​​structure.

[0090] The second support plate 160 includes a limiting part 161. The connection point between the second connecting plate 170 and the second support plate 160 is kept at a preset distance from the end of the second support plate 160 away from the first connecting plate 150. The preset distance forms the limiting part 161, thereby ensuring that the mounting cavity 110 has sufficient limiting depth and preventing the first end 210 from moving in the second direction and detaching from the mounting cavity 110.

[0091] The mounting bracket also includes a fixing plate 190, which is connected to the first support plate 140. The fixing plate 190 is positioned close to the geometric center of the first support plate 140 along the first direction. The wall of the fixing plate 190 is connected to the side of the purlin by screws or other fixing structures, thereby fixing the mounting bracket 100.

[0092] The photovoltaic system also includes a reset member disposed in the mounting cavity 110. Both ends of the reset member abut against the first end 210 and the first connecting plate 150 of the mounting support 100, respectively. The reset member is configured to provide a leftward abutment force to the first end 210 in a first direction. The reset member helps to further increase the resistance to the rightward movement of the first end 210 in the first direction, thereby further improving the stability of the photovoltaic module 200 mounting structure.

[0093] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0094] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
