Description

Technical Field

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

[0002] Under the national strategies of "carbon peaking" and "carbon neutrality," the requirements for energy conservation and environmental protection of buildings are becoming increasingly stringent, and low-carbonization is an inevitable trend. Building-integrated photovoltaics (BIPV), combined with supporting products such as intelligent shading, thermal insulation, and security enclosures, is an important technological path to achieve the "dual carbon" goals of the construction industry.

[0003] In building envelope construction, railings are an indispensable part, and there is a wide variety of railing products available, mainly including aluminum alloy railings, aluminum alloy tempered glass railings, and stainless steel railings. Railings are typically installed on balconies and terraces, areas with good lighting and views. In related technologies, incorporating photovoltaic modules into the railing structure not only provides aesthetic appeal and safety, but also offers energy-saving advantages, reducing building energy consumption and generating revenue.

[0004] However, if photovoltaic modules are directly installed in the railing structure, the photovoltaic modules cannot be arranged continuously and closely, and the handrails and posts in the railing will cast shadows on the photovoltaic modules, affecting the power generation area of ​​the photovoltaic modules and thus affecting the power generation capacity of the photovoltaic modules.

[0013] The second connecting part is provided opposite to and spaced apart from the first connecting part along the thickness direction of the photovoltaic module; the first groove is located between the first connecting part and the second connecting part, and the second connecting part is located between the photovoltaic module and the column;

[0014] The third connecting part is connected to the side of the groove bottom wall of the second connecting part away from the first groove, located on the side of the second connecting part facing the first connecting part, and intersecting with the second connecting part; the third connecting part covers part of the groove opening of the first groove, and the side of the third connecting part away from the second connecting part is connected to the side of the photovoltaic module facing the column.

[0015] In one embodiment, in the correspondingly arranged column and photovoltaic module, the side of the photovoltaic module near the bottom wall of the first groove is the first side surface, and both the fixing member and the first groove extend along the extension direction of the first side surface.

[0017] A buffer is disposed in the first groove, located between the bottom wall of the first groove and the photovoltaic module, and the buffer abuts against the bottom wall of the first groove and the photovoltaic module on both sides along the first direction.

[0018] In one embodiment, the photovoltaic railing further includes:

[0019] The handrail is located on the side of the photovoltaic module away from the fixing component and connects to the column and the photovoltaic module.

[0020] In one embodiment, a second groove is provided on the side of the handrail facing the photovoltaic module, and the end of the photovoltaic module facing away from the fixing member is accommodated in the second groove.

[0021] In one embodiment, a third groove is provided on the side of the handrail facing the photovoltaic module; the second and third grooves are spaced apart along the thickness direction of the photovoltaic module, and the end of the column away from the fixing member is accommodated in the third groove.

[0022] In one embodiment, the photovoltaic railing also includes a shielding element;

[0023] The third groove includes a first sub-groove and a second sub-groove that are connected to each other, and the first and second sub-grooves are arranged along the extension direction of the third groove; the end of the column away from the fixing member is connected to the handrail; the shielding member covers the opening of the second sub-groove and is connected to the handrail.

[0024] In one embodiment, the photovoltaic module includes:

[0025] The photovoltaic body is partially disposed within the first groove and connected to the fixing component;

[0026] The junction box is at least partially located within the first recess and connected to the photovoltaic body;

[0027] The cable, at least partially located within the first recess, is connected to the junction box.

[0028] In one embodiment, there are multiple columns, which are spaced apart; one photovoltaic module is correspondingly set with two columns, and the photovoltaic module is set between the corresponding two columns; the multiple columns are arranged in a non-linear manner.

[0031] Thus, in the corresponding arrangement of the columns and photovoltaic modules, the columns are positioned on one side of the photovoltaic module's thickness direction and spaced apart from it. This prevents the columns from contacting the photovoltaic modules, thus avoiding any shadow cast by the columns that would obscure the connected portion of the photovoltaic module. In other words, the shadow cast by the columns does not block the photovoltaic modules, thereby increasing the power generation area and output of the photovoltaic modules. Simultaneously, because the fastener has a first groove, one end of the photovoltaic module along the first direction is accommodated within this groove. This allows the fastener to connect the photovoltaic module and the column while simultaneously accommodating one end of the photovoltaic module, improving the aesthetics of the photovoltaic railing.

[0047] 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.

[0048] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0049] It should be understood that when an element or layer is referred to as "on," "adjacent to," "connected to," or "coupled to" other elements or layers, it may be directly on, adjacent to, connected to, or coupled to other elements or layers, or there may be intervening elements or layers. Conversely, when an element is referred to as "directly on," "directly adjacent to," "directly connected to," or "directly coupled to" other elements or layers, there are no intervening elements or layers. It should be understood that although the terms first, second, third, etc., may be used to describe various elements, parts, regions, layers, doping types, and / or portions, these elements, parts, regions, layers, doping types, and / or portions should not be limited by these terms. These terms are only used to distinguish one element, part, region, layer, doping type, or portion from another element, part, region, layer, doping type, or portion. Therefore, without departing from the teachings of this application, the first element, part, region, layer, doping type, or portion discussed below may be referred to as a second element, part, region, layer, or portion.

[0050] Spatial relation terms such as “below,” “under,” “below,” “under,” “above,” “above,” etc., are used herein to describe the relationship between one element or feature shown in the figure and other elements or features. It should be understood that, in addition to the orientation shown in the figure, spatial relation terms also include different orientations of the device in use and operation. For example, if the device in the figure is flipped, the element or feature described as “below,” “under,” or “below” will be oriented “above” the other element or feature. Therefore, the exemplary terms “below” and “under” can include both above and below orientations. Furthermore, the device may also include other orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptive terms used herein will be interpreted accordingly.

[0051] When used herein, the singular forms of “a,” “an,” and “ / the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising / including” or “having,” etc., specify the presence of the stated features, wholes, steps, operations, components, parts, or combinations thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof. Meanwhile, in this specification, the term “and / or” includes any and all combinations of the associated listed items.

[0052] Embodiments of the application are described herein with reference to cross-sectional views illustrating ideal embodiments (and intermediate structures), thus allowing for the expectation of variations in the illustrated shapes due to, for example, manufacturing techniques and / or tolerances. Therefore, embodiments of the application should not be limited to the specific shapes of the regions shown herein, but rather include shape deviations due to, for example, manufacturing techniques. For instance, implantation regions shown as rectangular typically have rounded or curved features at their edges and / or implantation concentration gradients, rather than a binary change from implantation regions to non-implantation regions. Similarly, buried regions formed by implantation can result in some implantation in the region between the buried region and the surface traversed during implantation. Therefore, the regions shown in the figures are substantially schematic, and their shapes do not represent the actual shapes of regions of the device and do not limit the scope of the application.

[0053] It should be noted that under the national strategies of "carbon peaking" and "carbon neutrality", the requirements for energy conservation and environmental protection of buildings are becoming increasingly stringent, and low-carbonization is an inevitable trend. Building-integrated photovoltaics, combined with supporting products such as intelligent shading, thermal insulation, and security enclosure, is an important technological path to achieve the "dual carbon" goals of the construction industry.

[0054] In building envelope construction, railings are an indispensable part, and there is a wide variety of railing products available, mainly including aluminum alloy railings, aluminum alloy tempered glass railings, and stainless steel railings. Railings are typically installed on balconies and terraces, areas with good lighting and views. In related technologies, incorporating photovoltaic modules into the railing structure not only provides aesthetic appeal and safety, but also offers energy-saving advantages, reducing building energy consumption and generating revenue.

[0055] However, directly integrating photovoltaic (PV) modules into the railing structure presents several problems. First, traditional PV modules have densely packed cells with low light transmittance, obstructing the view and appearing unsightly. Second, the glass panels in traditional PV railings are relatively small; replacing them with PV modules directly results in low utilization of the effective power generation area. Third, PV modules require pre-drilled mounting holes, affecting the cell arrangement area and reducing cost-effectiveness. Fourth, the overall structure fails to consider the aesthetics of concealing the module junction boxes, connectors, and connecting wires. Fifth, the handrails and posts will cast shadows, hindering PV module power generation.

[0056] Reference Figure 1 , Figure 2 and Figure 3 As shown, this application embodiment provides a photovoltaic railing 10, including at least one photovoltaic module 11, at least one post 12, and a fixing member 13. The post 12 is correspondingly arranged with the photovoltaic module 11. In the corresponding arrangement of the post 12 and the photovoltaic module 11, the post 12 is located on one side of the photovoltaic module 11 in the thickness direction and is spaced apart from the photovoltaic module 11; the post 12 extends along a first direction; the fixing member 13 is located on the side of the post 12 facing the photovoltaic module 11, connects the post 12 and the photovoltaic module 11, and is located at one end of the photovoltaic module 11 along the first direction; the fixing member 13 has a first groove 131, and one end of the photovoltaic module 11 along the first direction is accommodated in the first groove 131; wherein, the first direction intersects with the thickness direction of the photovoltaic module 11.

[0057] It should be noted that the first direction in this application is... Figure 1 In the X direction, the thickness direction of the photovoltaic module 11 in this application is... Figure 1 The thickness direction of the photovoltaic module 11 is either the Y direction or the Z direction, where the thickness direction of the photovoltaic module 11 is the direction from the light-incident surface to the light-exit surface of the photovoltaic module 11.

[0058] For example, for ease of understanding, see [reference]. Figure 1 As shown, the column 12 is located on one side of the photovoltaic module 11 in the thickness direction, meaning the column 12 is located on the inner side of the photovoltaic module 11. The subsequent detailed embodiments of this application will be exemplified by the example of the column 12 being located on the inner side of the photovoltaic module 11. Of course, the column 12 of this application can also be located on the outer side of the photovoltaic module 11. Here, this application does not limit the specific location of the column 12 on one side of the photovoltaic module 11 in the thickness direction.

[0059] Thus, in the corresponding arrangement of the column 12 and photovoltaic module 11, the column 12 is located inside the photovoltaic module 11 and spaced apart from it. This ensures that the column 12 in the photovoltaic railing 10 will not contact the photovoltaic module 11, preventing the shadow cast by the column 12 from obscuring the portion of the photovoltaic module 11 connected to it. In other words, the shadow cast by the column 12 will not obscure the photovoltaic module 11, thereby increasing the power generation area and power output of the photovoltaic module 11. Simultaneously, because the fixing member 13 has a first groove 131, the bottom end of the photovoltaic module 11 along the first direction is accommodated within the first groove 131. This allows the fixing member 13 to connect the photovoltaic module 11 and the column 12 while simultaneously accommodating the bottom end of the photovoltaic module 11, improving the aesthetics of the photovoltaic railing 10.

[0060] Specifically, the posts 12 in the photovoltaic railing 10 are positioned inside the photovoltaic module 11 along its thickness direction and are spaced a certain distance from the photovoltaic module 11. This layout prevents the posts 12 from directly contacting the photovoltaic module 11, thus avoiding the situation where the shadow cast by the posts 12 under sunlight would obstruct the portion of the photovoltaic module 11 connected to the posts 12. In other words, the spaced design of the posts 12 prevents the shadows of the posts 12 from overlapping on the surface of the photovoltaic module 11, allowing the photovoltaic module 11 to fully utilize its light transmission capacity, reducing additional obstruction of the line of sight, and ensuring that the shadows cast by the posts 12 do not obstruct the photovoltaic module 11. This, in turn, ensures that the effective power generation area of ​​the photovoltaic module 11 is not reduced, ultimately achieving the effect of increasing the power generation capacity of the photovoltaic module 11.

[0061] Secondly, the fixing member 13 of the photovoltaic railing 10 has a first groove 131, and the fixing member 13 is located on the side of the post 12 facing the photovoltaic module 11, connecting the post 12 and the photovoltaic module 11, and is located at one end of the photovoltaic module 11 along the first direction. The bottom end of the photovoltaic module 11 along the first direction can be accommodated in the first groove 131 of the fixing member 13, so that during the connection of the photovoltaic module 11 and the post 12, the first groove 131 of the fixing member 13 can accommodate the bottom end of the photovoltaic module 11, cleverly hiding the originally exposed connection part, avoiding the unsightly problem of exposed connection parts in traditional designs, thereby improving the overall aesthetics of the photovoltaic railing 10.

[0062] Furthermore, the fixing member 13 of the photovoltaic railing 10 connects the post 12 and the photovoltaic module 11, and the fixing member 13 is located at the bottom end of the photovoltaic module 11 along the first direction. Together with the first groove 131, it accommodates and fixes the bottom end of the photovoltaic module 11, forming a stable connection structure. This structure can effectively disperse and withstand external forces. Whether it's a collision during daily use or encountering severe weather such as strong winds, it ensures that the photovoltaic railing 10 remains stable, thereby enhancing the structural stability of the photovoltaic railing 10 and extending its service life.

[0063] Furthermore, the fastener 13 accommodates the bottom of the photovoltaic module 11 through the "first groove 131," fixing the photovoltaic module 11 only at its bottom along the first direction, rather than fixing it around the perimeter or at multiple points as in traditional solutions. This unilateral fixing method reduces the constraints of the installation structure on the size of the photovoltaic module 11, allowing the photovoltaic module 11 to be flexibly adjusted in size according to the actual shape of the glass grid (such as rectangular, square, etc.), thereby maximizing the utilization of the grid area. Simultaneously, the column 12 and the photovoltaic module 11 are spaced apart in the thickness direction, rather than directly contacting the front of the photovoltaic module 11 as in traditional solutions. This means that the photovoltaic module 11 does not need to reserve shading space for the column 12 in the horizontal or vertical direction, and can completely cover the horizontal or vertical width of the glass grid, thereby further optimizing the grid area of ​​the photovoltaic railing 10.

[0064] Understandably, the fastener 13 is provided with a "first groove 131," and the bottom end of the photovoltaic module 11 along the first direction is directly embedded into the groove, and fixed by mechanical clamping or structural adhesive. This method eliminates the need to drill holes on the surface or edges of the photovoltaic module 11, avoiding damage to the cell arrangement area caused by mounting holes.

[0065] It should be further explained that the correspondence between the pillar 12 and the photovoltaic module 11 can be one pillar 12 corresponding to one photovoltaic module 11, two pillars 12 corresponding to one photovoltaic module 11, or one pillar 12 corresponding to multiple photovoltaic modules 11. This application does not limit the specific correspondence between the pillar 12 and the photovoltaic module 11. For ease of explanation, please refer to... Figure 1 As described above, in this application, a photovoltaic module 11 has columns 12 corresponding to both ends.

[0066] In this way, the corresponding columns 12 on both sides of the photovoltaic module 11 form a "two-point support" system, which allows the self-weight of the photovoltaic module 11, wind load, and other loads to be evenly transferred through the columns 12 on both sides. This avoids the eccentric bending moment that may occur with single-point support, and can reduce the risk of deformation of the photovoltaic module 11 frame or loosening of the connectors. At the same time, the center of gravity of the photovoltaic module 11 is usually located at the geometric center. When the columns 12 on both sides are set up, the support points and the center of gravity form a symmetrical layout, ensuring that the load is vertically transferred to the foundation of the column 12, and avoiding tilting of the column 12 or uneven stress on the foundation due to eccentric support.

[0067] In one embodiment, see [reference] Figure 4 and Figure 5As shown, the fastener 13 includes a first connecting portion 132, a second connecting portion 133, and a third connecting portion 134. The second connecting portion 133 and the first connecting portion 132 are arranged opposite to each other and spaced apart along the thickness direction of the photovoltaic module 11; the first groove 131 is located between the first connecting portion 132 and the second connecting portion 133, and the second connecting portion 133 is located between the photovoltaic module 11 and the column 12; the third connecting portion 134 is connected to the side of the second connecting portion 133 away from the bottom wall of the first groove 131, located on the side of the second connecting portion 133 facing the first connecting portion 132, and the third connecting portion 134 intersects with the second connecting portion 133; the third connecting portion 134 covers part of the groove opening of the first groove 131, and the side of the third connecting portion 134 away from the second connecting portion 133 is connected to the side of the photovoltaic module 11 facing the column 12.

[0068] Thus, the fastener 13 achieves three-dimensional fixation of the photovoltaic module 11 through the coordinated action of the first connecting part 132, the second connecting part 133, and the third connecting part 134. The first connecting part 132 and the second connecting part 133 are arranged opposite each other along the thickness direction of the photovoltaic module 11 to form a first groove 131 to accommodate the edge of the photovoltaic module 11, and restrict the movement of the photovoltaic module 11 in the thickness direction by clamping. The third connecting part 134 covers part of the groove of the first groove 131 and connects to the side of the photovoltaic module 11 to form a lateral limit, which can prevent the photovoltaic module 11 from being dislodged by external force and ensure that the photovoltaic module 11 is firmly installed.

[0069] On the other hand, the third connection 134 covers the opening of the first groove 131, preventing rainwater from directly entering the first groove 131. When used with sealant, it can further block moisture penetration, preventing corrosion of the cells and circuits inside the photovoltaic module 11. Meanwhile, the second connection 133 is located between the photovoltaic module 11 and the column 12, and can isolate the two with elastic material, absorbing the thermal expansion and contraction stress of the photovoltaic module 11 caused by temperature changes, reducing the risk of backsheet wear and cell microcracks.

[0070] In addition, the first connecting part 132, the second connecting part 133 and the third connecting part 134 bear loads in different directions. The first connecting part 132 bears tensile force, the second connecting part 133 bears compressive force, and the third connecting part 134 bears shear force, forming a three-dimensional stress network that evenly distributes external force to the edge of the photovoltaic module 11, avoiding stress concentration when a single component is fixed in the traditional way, reducing the possibility of glass cracking and improving the safety of the structure.

[0071] For example, the third connection part 134 is connected to the photovoltaic module 11 by adhesive.

[0072] In this way, the connection reliability between the third connection part 134 and the photovoltaic module 11 can be improved. At the same time, the adhesive connection does not require drilling, welding or complex mechanical fixing. It only requires applying adhesive and pressing to adhere, which is suitable for rapid on-site construction and convenient for operators.

[0073] In one embodiment, in the correspondingly arranged column 12 and photovoltaic module 11, the side of the photovoltaic module 11 near the bottom wall of the first groove 131 is the first side surface, and the fixing member 13 and the first groove 131 both extend along the extension direction of the first side surface.

[0074] Thus, the fastener 13 and the first groove 131 are arranged along the extension direction of the first side to form a long strip-shaped linear fixing structure 20. This design can continuously bear the load along the edge of the photovoltaic module 11, and evenly distribute the external forces such as the self-weight of the photovoltaic module 11 and wind load on a longer contact surface, avoiding local stress concentration caused by single-point force and improving the overall stability of the fixing structure 20.

[0075] Furthermore, the photovoltaic module 11 is mostly a rectangular plate structure, and the first side usually extends along the length or width direction. The design of the fastener 13 extending in the same direction as the first groove 131 can closely fit the edge contour of the photovoltaic module 11, maximizing the contact area between the fastener 13 and the photovoltaic module 11.

[0076] In one embodiment, see [reference] Figure 2 and Figure 5 As shown, the photovoltaic railing 10 also includes a buffer member 14. The buffer member 14 is disposed in the first groove 131, located between the bottom wall of the first groove 131 and the photovoltaic module 11, and the two sides of the buffer member 14 along the first direction respectively abut against the bottom wall of the first groove 131 and the photovoltaic module 11.

[0077] Thus, the buffer 14, filling the space between the bottom wall of the first groove 131 and the photovoltaic module 11, can absorb the impact force of external loads on the photovoltaic module 11. When the photovoltaic module 11 is subjected to external forces such as wind loads and vibrations, the buffer 14 disperses stress through elastic deformation, preventing glass cracking or microcracks in the cells caused by direct hard contact between the bottom wall of the groove and the photovoltaic module 11. For example, in strong winds, the buffer 14 can alleviate the compressive stress of the fixing member 13 on the edge of the photovoltaic module 11, protecting the internal structure of the photovoltaic module 11 from damage.

[0078] Meanwhile, the elastic properties of the buffer 14 can compensate for dimensional deviations and thermal expansion and contraction deformation between the photovoltaic module 11 and the fixing member 13. When the ambient temperature changes, the displacement caused by the thermal expansion and contraction of the photovoltaic module 11 along the first direction can be absorbed by the buffer 14, preventing the fixing member 13 from loosening or the module from breaking due to the accumulation of deformation stress. In addition, the buffer 14 can also be adapted to photovoltaic modules 11 of different thicknesses, and the filling gap can be adjusted by the compression amount to improve the compatibility of the fixing structure 20.

[0079] In one embodiment, see [reference] Figure 6 and Figure 7 As shown, the photovoltaic railing 10 also includes a handrail 15. The handrail 15 is located on the side of the photovoltaic module 11 away from the fixing member 13 and is connected to the post 12 and the photovoltaic module 11.

[0080] Thus, the handrail 15, as a core safety component of the photovoltaic railing 10, provides users with a gripping support point to prevent accidental falls. For example, in scenarios such as balconies and stairs, the handrail 15 can withstand the force of a person leaning or gripping, and through its connection with the column 12 and photovoltaic module 11, it transfers the load to the overall structure, ensuring that the safety protection performance of the photovoltaic railing 10 meets the requirements of building codes.

[0081] In one embodiment, see [reference] Figure 6 and Figure 7 As shown, a second groove 151 is provided on the side of the handrail 15 facing the photovoltaic module 11, and the top of the photovoltaic module 11 away from the fixing member 13 is accommodated in the second groove 151.

[0082] Thus, the second groove 151 provides a top constraint structure for the photovoltaic module 11. Through the design of "the second groove 151 accommodating the top of the photovoltaic module 11", a three-dimensional clamping structure is formed at both ends (fixed member 13 and handrail 15). For example, the bottom of the photovoltaic module 11 is connected to the column 12 through the fixed member 13, and the top of the photovoltaic module 11 is embedded in the second groove 151 of the handrail 15. This can limit the displacement of the photovoltaic module 11 in the horizontal direction (such as swaying caused by wind) and the vertical direction (such as sagging caused by gravity), avoid structural loosening caused by a single fixed point, and improve the overall installation strength.

[0083] Furthermore, after the top of the photovoltaic module 11 is embedded in the second groove 151, the gap between the photovoltaic module 11 and the groove wall can be filled with sealant to form a top waterproof barrier. For example, the bottom wall of the second groove 151 can be designed as an inclined structure to guide rainwater to flow down along the outside of the groove opening, and together with the sealant, block the path of water vapor to penetrate into the interior of the photovoltaic module 11, so as to avoid damage to the cells or circuits due to moisture.

[0084] In one embodiment, a third groove 152 is provided on the side of the handrail 15 facing the photovoltaic module 11; the second groove 151 and the third groove 152 are spaced apart along the thickness direction of the photovoltaic module 11, and the top of the column 12 away from the fixing member 13 is accommodated in the third groove 152.

[0085] Thus, the second groove 151 accommodates the top of the photovoltaic module 11, and the third groove 152 fixes the top of the column 12, forming a closed-loop connection structure of "fixture 13 (bottom) - photovoltaic module 11 - handrail 15 (top) - column 12". The bottom of the photovoltaic module 11 is connected to the bottom of the column 12 through the fixation 13, and the top is embedded in the second groove 151 of the handrail 15. At the same time, the top of the column 12 is inserted into the third groove 152, so that the three are interlocked at the top through the handrail 15, effectively limiting the displacement of the photovoltaic module 11 in the horizontal, vertical and thickness directions, and avoiding the risk of shaking at a single fixed point.

[0086] In addition, the mating area between the third groove 152 and the top of the column 12 can be filled with sealant, which, combined with the sealing design between the second groove 151 and the photovoltaic module 11, forms a double-layer waterproof barrier for the handrail 15. When rainwater flows along the surface of the handrail 15, the groove wall of the third groove 152 can prevent rainwater from seeping into the connection gap between the column 12 and the handrail 15, thus preventing corrosion inside the column 12 or moisture damage to electrical components.

[0087] In one embodiment, see [reference] Figure 8 As shown, the photovoltaic railing 10 also includes a shielding element 16. (See reference...) Figures 9-12 As shown, the third groove 152 includes a first sub-groove 1521 and a second sub-groove 1522 that are connected. The first sub-groove 1521 and the second sub-groove 1522 are arranged along the extension direction of the third groove 152. The end of the column 12 facing away from the fixing member 13 is connected to the handrail 15. The shielding member 16 covers the opening of the second sub-groove 1522 and is connected to the handrail 15.

[0088] For example, the post 12 is located in the first sub-groove 1521, and the end of the post 12 facing away from the fixing member 13 is connected to the side wall of the handrail 15. Thus, since the first sub-groove 1521 accommodates the top of the post 12, it provides basic support and lateral restraint; the second sub-groove 1522 communicates with the first sub-groove 1521, forming a "stepped" fixing structure 20 along the extension direction of the post 12. After the post 12 is inserted into the first sub-groove 1521, the shielding member 16 covers the second sub-groove 1522 and is fixed to the handrail 15. The top of the post 12 can be connected to the side wall of the handrail 15 by bolts, preventing the post 12 from moving up and down or rotating, realizing three-dimensional (horizontal, vertical, and rotational) constraints, thereby improving the overall stability and reliability of the photovoltaic railing 10.

[0089] Of course, see Figure 11 and Figure 12 As shown, the top of the column 12 is connected to the top wall of the handrail 15. The first sub-groove 1521 is located on both sides of the column 12 along the extension direction of the third groove 152. On the one hand, the connection between the top of the column 12 and the top wall of the handrail 15 can improve the connection stability between the column 12 and the handrail 15. On the other hand, a clearance space can be formed in the first sub-groove 1521 on both sides of the column 12 to facilitate the connection between the column 12 and the handrail 15.

[0090] It should be noted that this application does not limit the specific location of the first sub-groove 1521. The first sub-groove 1521 can be arranged on at least one side of the column 12 along the extension direction of the third groove 152, or the column 12 can be located within the first sub-groove 1521, as long as the first sub-groove 1521 and the second sub-groove 1522 are arranged along the extension direction of the third groove 152 and the blocking member 16 covers the opening of the second sub-groove 1522. Here, the location of the first sub-groove 1521 is not limited or described in detail.

[0091] Furthermore, after the shielding member 16 covers the opening of the second sub-groove 1522, waterproof adhesive can be filled at the joint between the shielding member 16 and the handrail 15 and the column 12 to form a double-layer waterproof structure: the gap between the first sub-groove 1521 and the column 12 is waterproofed by sealant, and after the second sub-groove 1522 is sealed by the shielding member 16, rainwater can be prevented from seeping into the handrail 15 from the opening, thus avoiding corrosion of the top of the column 12 or moisture damage to electrical components.

[0092] Understandably, the shielding component 16 is flush with the surface of the handrail 15 or has a streamlined transition, concealing the groove and internal structure of the second sub-groove 1522, making the connection between the column 12 and the handrail 15 simpler. For example, the shielding component 16 can be made of the same material or color as the handrail 15 to avoid exposed gaps affecting aesthetics and achieve the integrated effect of "photovoltaic power generation + architectural decoration".

[0093] In one embodiment, the photovoltaic module 11 includes a photovoltaic body 111, a junction box 112, and cables. The photovoltaic body 111 is partially disposed within a first groove 131 and connected to a fixing member 13; the junction box 112 is at least partially disposed within the first groove 131 and connected to the photovoltaic body 111; the cables are at least partially disposed within the first groove 131 and connected to the junction box 112.

[0094] Thus, the internal space of the first groove 131 provides a dedicated installation area for electrical accessories such as the junction box 112 and cables. Through the closed design of the bottom third connection part 134, these components are completely hidden inside the first groove 131. For example, the junction box 112 can be fixed to the bottom of the first groove 131, and the cables are connected through the pre-set wiring holes in the first groove 131. Only the glass surface of the photovoltaic module 11 is visible from the outside, which can avoid visual clutter caused by exposed wiring and thus improve the aesthetics of the photovoltaic railing 10.

[0095] In one embodiment, there are multiple columns 12, which are spaced apart; one photovoltaic module 11 is correspondingly arranged with two columns 12, and the photovoltaic module 11 is arranged between the corresponding two columns 12; the multiple columns 12 are arranged in a non-linear manner.

[0096] Thus, the non-linear arrangement of the columns 12 (such as zigzag, arc, or wave shapes) can alter the direction of wind load, dispersing wind force through structural shape and reducing concentrated stress in a single direction. For example, an arc-shaped arrangement of the columns 12 can disperse wind load along the curved surface, reducing the lateral pressure on individual columns 12 and improving the stability of the photovoltaic railing 10 in strong winds. Simultaneously, the non-linear arrangement of the columns 12 can flexibly adapt to non-linear architectural scenarios such as balcony corners, curved curtain walls, and spiral staircases. For example, in a circular balcony, the columns 12 are arranged along a circular arc, and the photovoltaic modules 11 can be customized into a fan shape, allowing the photovoltaic railing 10 to perfectly fit the building's contours and avoiding spatial mismatch caused by a straight arrangement.

[0097] In one embodiment, a plurality of columns 12 are arranged in a straight line.

[0098] In this way, the multiple columns 12 arranged in a straight line allow the photovoltaic railing 10 to be applied to straight building boundaries such as balconies, corridors, and single-level railings. For example, the straight railing of a rectangular balcony can be perpendicular or parallel to the building facade, forming a simple and neat visual effect that meets the requirements of modern architecture for the uniformity of lines. At the same time, the straight arrangement can maximize the use of straight space and avoid gaps or redundant spaces generated by non-straight layouts in regular interfaces, which is especially suitable for scenarios with high space utilization requirements such as industrial buildings and warehousing facilities.

[0099] Optionally, during the installation of the photovoltaic railing 10, the post-installed embedded parts are pre-installed on the fixed structure 20 according to the grid positioning of the photovoltaic railing 10, and then the posts 12 are welded to the post-installed embedded parts. Further, expansion bolts for installing the fixing parts 13 are fixed to the fixed structure 20 according to the grid dimensions of the photovoltaic railing 10, thereby fixing the fixing parts 13 to the fixed structure 20, and the fixing parts 13, posts 12, and handrails 15 are fixedly connected by connecting brackets, screws, and other connecting parts. Based on the above, photovoltaic modules 11 are installed in the first groove 131 of the fixing parts 13, specifically including the installation of the photovoltaic body 111, junction box 112, and cables. Finally, the locations in the photovoltaic railing 10 that require fastening are sealed and fixed with sealant.

[0100] It should be noted that the photovoltaic railing 10 of this application does not necessarily have to be installed in strict accordance with the above steps. Operators can make adaptive adjustments according to the actual installation process. Here, this application will not elaborate on or limit the specific installation process.

[0101] 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.

[0102] The above embodiments merely illustrate 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.
