Description

Technical Field

[0001] This application relates to the field of building-integrated photovoltaics (BIPV) technology, and more particularly to a photovoltaic facade system, a photovoltaic module frame, and connecting brackets. Background Technology

[0002] Solar photovoltaic power generation is a clean power generation device. Integrating solar panels with buildings is a way to save urban land and reduce indoor energy consumption. Industrial plant facades also have a large area that can be used to install solar panels, which can reduce the heat of the original building facade.

[0003] Currently, during the installation of solar panels on a building facade, the photovoltaic modules need to be held by hand before the mounting blocks are installed. This often results in the photovoltaic modules falling and shifting, increasing the difficulty of installation. In addition, after installation, the photovoltaic modules may sway from side to side, leading to misalignment or even falling. Utility Model Content

[0004] The purpose of this application is to provide a photovoltaic facade system, a photovoltaic module frame, and connecting brackets to prevent sagging and misalignment during the installation of solar panels, thereby reducing processing difficulty and improving installation efficiency.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A connector, comprising:

[0007] The mounting body has a connecting part for fixed connection with the facade;

[0008] At least one hook, the end of which is fixedly connected to the hanging body;

[0009] At least one limiting spring is provided, one end of which is fixedly connected to the hanging body, and the limiting spring and the hook are staggered along the first direction.

[0010] When installing photovoltaic modules on a facade using the connecting brackets provided in this application embodiment, the connecting brackets are first installed in the gap between adjacent facades. The connecting brackets are then fixed to the facades via connecting portions on the bracket body, with the first direction aligned along the length of the gap. Next, the mounting grooves on the photovoltaic module frame mate with the connecting brackets. Specifically, as shown... Figure 16 As shown, move the photovoltaic module so that the hook extends into the notch of the photovoltaic module frame. The hook moves along the notch until it moves into the hanging hole, as shown. Figure 17Then, the hook is moved along the hanging hole, causing it to engage inside the hole. The entire photovoltaic module is then attached to the vertical surface through the engagement of the hook and the hanging hole. Furthermore, as the photovoltaic module is moved to allow the hook to move along the hanging hole, a limiting spring moves into the notch to prevent the photovoltaic module from moving along the first direction.

[0011] As shown above, during the installation of photovoltaic modules, the frame of the photovoltaic module is first hooked onto the hook of the connecting bracket. This ensures the hook extends into the hanging hole, preventing the photovoltaic module from falling or shifting, reducing processing difficulty and improving installation efficiency. Furthermore, the limiting spring moves into the notch, and its blocking action prevents the photovoltaic module from moving left or right along the first direction, thus preventing lateral swaying and avoiding misalignment or even falling.

[0012] In one possible implementation, the connecting hook includes at least one set of hooks, and each set of hooks includes two hooks arranged sequentially along a second direction, with the hook heads of the two hooks in the same set arranged opposite to each other; the first direction and the second direction intersect.

[0013] By adopting the above technical solution, the connecting brackets are installed in the narrow gap between adjacent facades, and the hooks of the same group on the connecting brackets are arranged opposite each other. In this way, the photovoltaic modules on adjacent facades can be hung and fixed at the same time using the hooks on the connecting brackets, thereby reducing the number of connecting brackets and simplifying the structure.

[0014] In one possible implementation, each hook has a limiting spring on both sides along the first direction; and / or, the connecting part includes a connecting hole, and the connecting hanger is fixedly connected to the vertical surface by bolts that mate with the connecting hole. In this way, regardless of whether the hook moves to the left or right along the hanging hole, the limiting spring can engage with the notch for restraint. Furthermore, during the processing of the hook, the hook body can be directly cut and bent to form the hook, with the remaining material on both sides of the hook forming the limiting spring, thus simplifying the processing steps.

[0015] In one possible implementation, the connecting bracket also includes a first buckle fixed to the bracket body; with this technical solution, without installing photovoltaic modules, the first cover plate can be installed using the first buckle, thereby covering the slit and making the overall facade flatter and more aesthetically pleasing.

[0016] Alternatively, the connecting bracket may also include a second clip fixed to the bracket body; using this technical solution, after the photovoltaic modules are installed, a second cover plate can be installed at the slit. The second cover plate engages with the second clip and covers the slit, and the structure after the second cover plate is installed is as follows. Figure 19As shown. In this way, the second cover plate is installed using the second clip, thereby covering the slit and making the surface of the photovoltaic facade system cleaner and more beautiful, while preventing wind and sand from invading the connecting parts inside the slit.

[0017] Alternatively, the connecting bracket may also include a first clip fixedly connected to the bracket body and a second clip detachably connected to the bracket body. The second clip and the first clip are located on the same side of the bracket body, with the second clip positioned higher than the first clip. This technical solution utilizes the height difference between the first and second clips, and allows for the removal or installation of the second clip depending on the actual scenario. This enables the installation of a cover plate within the slit both before and after the installation of photovoltaic modules to conceal the slit and maintain the overall flatness and aesthetics of the facade.

[0018] In one possible implementation, the connecting bracket further includes a second buckle and a pressing member that are detachably connected to the bracket body, the second buckle and the pressing member being an integral structure. Specifically, when the bottom of the first side plate is bent to form a pressing groove, after the pressing block is fixed to the bracket body, the pressing member can be pressed into the pressing groove of the photovoltaic module frame to further limit the photovoltaic module and prevent the photovoltaic module from shaking.

[0019] In one possible implementation, the pendant body, hook, and limiting spring are integrated into a single structure to facilitate manufacturing.

[0020] A photovoltaic module frame, comprising:

[0021] The first side plate, the support plate, and the baffle are located on the same side of the first side plate, and the support plate and the baffle are arranged opposite to each other to form a bearing groove.

[0022] The bottom of the first side plate is provided with a hanging groove, which includes a notch and a hanging hole communicating with the end of the notch.

[0023] During the installation of photovoltaic modules, such as Figure 16 As shown, move the photovoltaic module so that the hook extends into the notch of the photovoltaic module frame. The hook moves along the notch until it moves into the hanging hole, as shown. Figure 17 Then, the hook is moved along the hanging hole, causing it to engage inside the hole. The entire photovoltaic module is then attached to the vertical surface through the engagement of the hook and the hanging hole. Furthermore, as the photovoltaic module is moved to allow the hook to move along the hanging hole, a limiting spring moves into the notch to prevent the photovoltaic module from moving along the first direction.

[0024] In one possible implementation, there are hanging holes on both sides of the notch. Thus, after the hook moves along the notch until it enters the hanging hole, the photovoltaic module can be moved relative to either side of the notch relative to the vertical surface, depending on the actual scenario. This allows adjustment of the photovoltaic module's position along the length of the hanging hole, ensuring that multiple photovoltaic modules can be aligned after installation.

[0025] In one possible implementation, the bottom of the first side plate is bent to form a pressure groove, with the pressure groove and the support groove located on opposite sides of the first side plate, respectively. Thus, the support groove on one side of the first side plate supports the photovoltaic module, while the pressure groove on the other side engages with the pressure member of the connecting bracket for positioning. It is understood that after the bottom of the first side plate is bent to form the pressure groove, the notch can penetrate the groove wall.

[0026] A photovoltaic facade system includes a facade, a connecting bracket as described above, and a photovoltaic module frame as described above. The connecting bracket is fixedly connected to the facade, and the hook of the connecting bracket can pass through a notch in the photovoltaic module frame and move along a first direction into a hanging hole, and the limiting spring of the connecting bracket can be engaged into the notch.

[0027] Compared with the prior art, the beneficial effects of the photovoltaic facade system provided in this application embodiment are the same as those of the above-mentioned connecting brackets and photovoltaic module frames, and will not be repeated here.

[0028] In one possible implementation, the facade includes multiple vertical panels, with slits formed between adjacent panels, and connecting brackets disposed within these slits. This arrangement facilitates the installation of connecting brackets in the slits between adjacent panels, saves installation space, and improves the overall flatness of the facade.

[0029] In one possible implementation, the connecting bracket further includes a first clip fixed to the bracket body. Using this technical solution, without installing photovoltaic modules, a first cover plate can be installed using the first clip, thereby concealing the slit and increasing the overall flatness and aesthetics of the facade. The photovoltaic facade system also includes a first cover plate that engages with the first clip; alternatively, the connecting bracket further includes a second clip detachably connected to the bracket body; the photovoltaic facade system also includes a second cover plate that engages with the second clip. Installing the second cover plate using the second clip conceals the slit, making the surface of the photovoltaic facade system cleaner and more aesthetically pleasing, while also preventing wind and sand from intruding into the connecting bracket within the slit.

[0030] In one possible implementation, the connecting bracket further includes a pressing member detachably connected to the bracket body, the pressing member being able to press into a pressing groove in the frame. This further limits the position of the photovoltaic module and prevents it from shaking. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0062] Please see Figures 1-7 The connecting bracket A provided in this application embodiment includes a bracket body 1, at least one hook 3, and at least one limiting spring 2. The bracket body 1 can be any shape, such as a plate or block. The bracket body 1 has a connecting portion for fixed connection with a facade D, where the facade D can be a wall, core board, etc. The end of the hook 3 is fixedly connected to the bracket body 1. Specifically, there can be one or more hooks 3. The hook 3 and the bracket body 1 can be an integral structure, or the hook 3 and the bracket body 1 can be relatively fixed by welding, threaded parts, etc. The end of the hook 3 is fixedly connected to the bracket body 1, and the hook head of the hook 3 extends out to facilitate hooking and engaging with the photovoltaic module frame E. The hook 3 can be L-shaped. There can be one or more limiting springs 2, and one end of the limiting spring 2 is fixedly connected to the bracket body 1. Specifically, the limiting spring 2 and the bracket body 1 can be an integral structure, or the limiting spring 2 and the bracket body 1 can be relatively fixed by welding, threaded parts, etc. The other end of the limiting spring 2 extends out in a direction away from the hanging body 1. Furthermore, the limiting spring 2 and the hook 3 are staggered along a first direction, which can be the length direction of the slit B between two adjacent facades D.

[0063] Please see Figures 11-15 This application also provides a photovoltaic module frame E, which cooperates with the aforementioned connecting bracket A to install the photovoltaic module F on the facade D. Specifically, the photovoltaic module frame E includes a first side plate 9, a support plate 11, and a baffle 10. Figure 11 As shown, the baffle 10 and the support plate 11 are located on the same side of the first side plate 9. The support plate 11 and the baffle 10 are arranged opposite each other to form a bearing groove, that is, the space between the support plate 11 and the baffle 10 forms a bearing groove. The support plate 11 is used to support the lower surface of the photovoltaic module F, and the baffle 10 is used to limit the side or upper surface of the photovoltaic module F. A hanging groove 13 is provided at the bottom of the first side plate 9. The hanging groove 13 includes a notch 13a and a hanging hole 13b communicating with the end of the notch 13a. The notch 13a extends upward from the bottom edge of the first side plate 9, and the hanging hole 13b communicates with the end of the notch 13a. The angle between the center line of the hanging hole 13b and the center line of the notch 13a can be an acute angle or a right angle.

[0064] When installing the photovoltaic module F onto the facade D using the connecting bracket A provided in this application embodiment, firstly, the connecting bracket A is installed in the gap between adjacent facades D. The connecting bracket A is fixed relative to the facade D via the connecting portion on the bracket body 1, with the first direction set along the length of the gap. Then, the mounting groove 13 of the photovoltaic module frame E mates with the connecting bracket A. Specifically, as shown... Figure 16 As shown, the photovoltaic module F is moved so that the hook 3 extends into the notch 13a of the photovoltaic module frame E. The hook 3 moves along the notch 13a until it moves into the hanging hole 13b. Figure 17 Then, the hook 3 is moved along the hanging hole 13b, so that the hook 3 is locked inside the hanging hole 13b. The entire photovoltaic module F is hung on the vertical surface D through the cooperation of the hook 3 and the hanging hole 13b. Furthermore, during the process of moving the photovoltaic module F to move the hook 3 along the hanging hole 13b, the limiting spring 2 moves into the notch 13a, so as to use the blocking effect of the limiting spring 2 to prevent the photovoltaic module F from moving as a whole in the first direction.

[0065] As can be seen from the above, during the installation of photovoltaic module F, the frame E of photovoltaic module F is first hooked to the hook 3 of the connecting bracket A. This allows the hook 3 to extend into the hanging hole 13b, preventing the photovoltaic module F from falling or shifting, reducing processing difficulty and improving installation efficiency. Furthermore, when the limiting spring 2 moves into the notch 13a, its blocking effect prevents the photovoltaic module F from moving left or right along the first direction, thus preventing it from swaying left or right and avoiding misalignment or even falling.

[0066] Since photovoltaic modules F need to be installed on both adjacent facades D, that is, photovoltaic modules F need to be installed on both sides of the connecting bracket A, the connecting bracket A in this technical solution includes at least one set of hooks 3, and each set of hooks 3 includes two hooks 3 arranged sequentially along the second direction, such as... Figure 1 As shown, the hooks of two hooks 3 in the same group are positioned opposite each other; the first direction and the second direction intersect. The first direction and the second direction can be perpendicular to each other, or the angle between the first direction and the second direction can be an acute angle. The connecting bracket A can include one, two, or more groups of hooks 3, or multiple connecting brackets A can be used with the same photovoltaic module frame E.

[0067] By adopting the above technical solution, such as Figure 19 As shown, the connecting bracket A is installed in the slit B between adjacent facades D, and the hooks 3 of the same group on the connecting bracket A are arranged opposite each other. In this way, the photovoltaic modules F on the adjacent facades D can be hung and fixed at the same time using the hooks 3 on the connecting bracket A, thereby reducing the number of connecting brackets A and simplifying the structure.

[0068] like Figures 1-3 As shown, in some embodiments, limiting spring pieces 2 are provided on both sides of each hook 3 along the first direction. Thus, when the hook head slides into the hanging hole 13b, if the hook 3 moves to the left along the hanging hole 13b, the limiting spring piece 2 on the right side of the hook 3 can engage with the notch 13a; if the hook 3 moves to the right along the hanging hole 13b, the limiting spring piece 2 on the left side of the hook 3 can engage with the notch 13a. In this way, regardless of whether the hook 3 moves to the left or right along the hanging hole 13b, the limiting spring piece 2 can engage with the notch 13a for limiting. Furthermore, during the processing of the hook 3, it can be directly cut and bent on the hook 3 body to form the hook 3, and the remaining material on both sides of the hook 3 forms the limiting spring pieces 2, thus simplifying the processing steps.

[0069] like Figure 2 As shown, in some embodiments, the connecting part includes a connecting hole, and the connecting bracket A is fixedly connected to the facade D by a fastening bolt 7 that mates with the connecting hole. Specifically, to prevent stress concentration on the facade D, the fastening bolt 7 can be connected to a backing plate 8, which is fitted against the other side of the facade D to distribute stress. The fastening bolt 7 passes through the connecting bracket A, the facade D, and the backing plate 8 simultaneously, thereby fixing the three components together. Figure 4 As shown, in order to prevent the bolt head or nut from protruding from the backing plate 8 and affecting the flatness of the facade D, the backing plate 8 can also be provided with a countersunk hole 8a in this technical solution. The bolt head or nut is located in the countersunk hole 8a to avoid the bolt head or nut protruding from the surface of the backing plate 8, thereby ensuring a higher overall flatness of the facade D.

[0070] In other embodiments, such as Figure 1 As shown, the connecting bracket A may also include a first buckle 6, which is fixed to the bracket body 1. Specifically, the first buckle 6 and the bracket body 1 can be an integral structure, or the first buckle 6 and the bracket body 1 can be relatively fixed by welding, threaded connection, snap-fit, etc. Figure 7 and Figure 8 As shown, after the connecting bracket A is fixed in the slit B between adjacent facades D, without installing the photovoltaic module F, a first cover plate C can be installed at the slit B. The first cover plate C engages with the first buckle 6 and covers the slit B. The structure after installing the first cover plate C is as follows. Figure 20 As shown. Using this technical solution, without installing the photovoltaic module F, the first cover plate C can be installed using the first clip 6, thereby covering the slit B and making the facade D more flat and aesthetically pleasing.

[0071] In other embodiments, such as Figure 1 and Figure 2 As shown, the connecting bracket A also includes a second buckle 5 fixed to the bracket body 1. The second buckle 5 and the bracket body 1 can be an integral structure, or the second buckle 5 and the bracket body 1 can be detachably fixed to the bracket body 1 by means of threaded connection or snap-fit. Using this technical solution, after the photovoltaic module F is installed, a second cover plate G can be installed at the slit B. The second cover plate G snaps into the second buckle 5 and covers the slit B. The structure after the second cover plate G is installed is as follows. Figure 19 As shown. Thus, the second cover plate G is installed using the second clip 5, thereby covering the slit B, making the surface of the photovoltaic facade D system cleaner and more aesthetically pleasing, while preventing wind and sand from invading the connecting bracket A inside the slit B.

[0072] In other embodiments, when the connecting bracket A includes both a first latch 6 and a second latch 5, the first latch 6 is fixed to the bracket body 1, and the second latch 5 is detachably fixed to the bracket body 1. Furthermore, the second latch 5 and the first latch 6 are located on the same side of the bracket body 1, and the second latch 5 is positioned higher than the first latch 6. After the photovoltaic module F is installed, the depth of the slit B is relatively large, such as... Figure 20 As shown, the second cover plate G is installed using the higher second clip 5; before installing the photovoltaic module F, the depth of the slit B is relatively small, such as... Figure 19 As shown, the second clip 5 can be removed at this point, and then the first cover plate C can be installed using the lower first clip 6. This technical solution utilizes the height difference between the first clip 6 and the second clip 5, and allows for the removal or installation of the second clip 5 depending on the actual scenario. This enables the cover plate to be installed within the slit B both before and after the installation of the photovoltaic module F, thus concealing the slit B and maintaining the overall flatness and aesthetics of the facade D.

[0073] In the above embodiments, the first latch 6 and the second latch 5 can be staggered along the first direction to prevent affecting each other's installation space and hindering the snap-fit ​​installation of the first cover plate C and the second cover plate G. The first latch 6 and the second latch 5 can each include two opposing latching edges, with a notch formed between the two latching edges. The snap-fit ​​protrusion of the first cover plate C or the second cover plate G extends into the notch, thereby achieving snap-fit ​​between the notch and the first cover plate C or the second cover plate G.

[0074] In other embodiments, the connecting bracket A further includes a second buckle 5 and a pressing member 4. The second buckle 5 is detachably connected to the bracket body 1, and the second buckle 5 and the bracket body 1 can be detachably fixed to each other by means of threaded connection or snap-fit. The pressing member 4 is also detachably connected to the bracket body 1, and the pressing member 4 and the bracket body 1 can be detachably fixed to each other by means of threaded connection or snap-fit. Specifically, when the bottom of the first side plate 9 is bent to form a pressing groove 12, after the pressing block is fixed to the bracket body 1, the pressing member 4 can be pressed into the pressing groove 12 of the photovoltaic module frame E to further limit the photovoltaic module F and prevent the photovoltaic module F from shaking.

[0075] In the above embodiments, such as Figure 2 As shown, to simplify the structure, the second buckle 5 and the pressure member 4 can be a single unit, which facilitates their connection and disassembly. Specifically, the second buckle 5 and the pressure member 4 can be detachably fixed to the hanger body 1 using bolts. The cross-section of the pressure member 4 can be approximately "U". After the pressure member 4 is fixedly connected to the hanger body 1, its two sides are located on both sides of the hanger body 1 and press into the pressure grooves 12 of the photovoltaic module frame E on both sides of the slit B. The second buckle 5 can be formed by cutting and bending one end of the pressure member 4.

[0076] To facilitate manufacturing, the pendant body 1, hook 3, and limiting spring 2 of the pendant A can be a single integrated structure. Specifically, the pendant body 1, hook 3, and limiting spring 2 can be formed by bending and deforming a metal plate, or they can be formed by integral casting.

[0077] This application embodiment also provides a photovoltaic module frame E that mates with the aforementioned connecting bracket A, such as... Figures 9-12 As shown, the frame E contacts the edge of the photovoltaic module F to facilitate the frame E in supporting and fixing the photovoltaic module F. Figure 11As shown, the photovoltaic module frame E includes a first side plate 9, a support plate 11, and a baffle 10. A mounting groove 13 is provided at the bottom of the first side plate 9. The mounting groove 13 includes a notch 13a and a mounting hole 13b communicating with the end of the notch 13a. The notch 13a extends upward from the bottom edge of the first side plate 9, and the mounting hole 13b communicates with the end of the notch 13a. The angle between the centerline of the mounting hole 13b and the centerline of the notch 13a can be an acute angle or a right angle. During the installation of the photovoltaic module F, such as... Figure 16 As shown, the photovoltaic module F is moved so that the hook 3 extends into the notch 13a of the photovoltaic module frame E. The hook 3 moves along the notch 13a until it moves into the hanging hole 13b. Figure 17 Then, the hook 3 is moved along the hanging hole 13b, so that the hook 3 is locked inside the hanging hole 13b. The entire photovoltaic module F is hung on the vertical surface D through the cooperation of the hook 3 and the hanging hole 13b. Furthermore, during the process of moving the photovoltaic module F to move the hook 3 along the hanging hole 13b, the limiting spring 2 moves into the notch 13a, so as to use the blocking effect of the limiting spring 2 to prevent the photovoltaic module F from moving as a whole in the first direction.

[0078] In some embodiments, such as Figures 13-15 As shown, both sides of the notch 13a have hanging holes 13b, meaning that both ends of the notch 13a have hanging holes 13b, and the hanging holes 13b and the notch 13a together form a T-shape. Thus, after the hook 3 moves along the notch 13a until it enters the hanging hole 13b, the photovoltaic module F can be moved relative to the facade D towards either side of the notch 13a, depending on the actual scenario. This allows adjustment of the photovoltaic module F's position along the length of the hanging hole 13b, ensuring that multiple photovoltaic modules F can be aligned after installation.

[0079] In other embodiments, such as Figure 11 As shown, the bottom of the first side plate 9 is bent to form a pressure groove 12, which, along with the support groove, is located on both sides of the first side plate 9. Thus, the support groove on one side of the first side plate 9 supports the photovoltaic module F, while the pressure groove 12 on the other side cooperates with the pressure member 4 of the connecting bracket A for positioning. It can be understood that after the bottom of the first side plate 9 is bent to form the pressure groove 12, the notch 13a can penetrate the groove wall of the pressure groove 12.

[0080] In some embodiments, the frame E can be formed entirely by bending a metal plate, that is, the first side plate 9, the support plate 11, and the baffle 10 are all integral structures. Wire grooves 14 can also be provided at both ends of the frame E to facilitate the passage of wires.

[0081] This application also provides a photovoltaic facade system, which includes a facade D, a connecting bracket A provided in any of the above embodiments, and a photovoltaic module frame E provided in any of the above embodiments. The connecting bracket A is fixedly connected to the facade D. Specifically, the connecting bracket A is fixed relative to the facade D through the connecting part of the bracket body 1. The hook 3 of the connecting bracket A can pass through the notch 13a of the photovoltaic module frame E and move along the first direction into the hanging hole 13b, and the limiting spring 2 of the connecting bracket A can be engaged in the notch 13a. That is, the hook 3 moves along the notch 13a until the hook 3 moves into the hanging hole 13b, and then moves along the hanging hole 13b, so that the hook 3 is engaged inside the hanging hole 13b. The entire photovoltaic module F is hung on the facade D through the cooperation of the hook 3 and the hanging hole 13b. Furthermore, during the process of moving the photovoltaic module F so that the hook 3 moves along the hanging hole 13b, the limiting spring 2 moves into the notch 13a, so as to use the blocking effect of the limiting spring 2 to prevent the photovoltaic module F from moving as a whole in the first direction.

[0082] Compared with the prior art, the beneficial effects of the photovoltaic facade system provided in this application embodiment are the same as those of the above-mentioned connecting bracket A and photovoltaic module frame E, and will not be repeated here.

[0083] Facade D comprises multiple vertical panels, with a narrow gap B formed between adjacent panels. Connecting brackets A are installed within these gaps B. This arrangement facilitates the installation of connecting brackets A within the gaps B between adjacent panels, saves installation space, and improves the overall flatness of facade D.

[0084] like Figure 20 As shown, in the case that the connecting bracket A also includes a first buckle 6 fixed to the bracket body 1, the photovoltaic facade D system also includes a first cover plate C that engages with the first buckle 6. Using this technical solution, without installing the photovoltaic modules F, the first cover plate C can be installed using the first buckle 6, thereby concealing the slit B and making the facade D more flat and aesthetically pleasing.

[0085] like Figure 19 As shown, when the connecting bracket A also includes a second clip 5 detachably connected to the bracket body 1, the photovoltaic facade D system also includes a second cover plate that engages with the second clip 5. The second cover plate is installed using the second clip 5 to cover the slit B, making the surface of the photovoltaic facade D system cleaner and more aesthetically pleasing, while also preventing wind and sand from invading the connecting bracket A within the slit B.

[0086] In some other embodiments, when the connecting bracket A also includes a pressing member 4 that is detachably connected to the bracket body 1, after the pressing block is fixed to the bracket body 1, the pressing member 4 can be pressed into the pressing groove 12 of the photovoltaic module frame E to further limit the photovoltaic module F and prevent the photovoltaic module F from shaking.

[0087] In addition, such as Figures 21-22 As shown, the photovoltaic facade system may further include a third cover plate H. The extension direction of the third cover plate H may be perpendicular to the extension directions of the first cover plate C and the second cover plate, so as to cover the slit B on the other edge of the facade D. Elastic clips may be provided at both ends of the third cover plate H to allow it to be secured within the slit B, thereby ensuring the overall flatness of the photovoltaic facade system and enhancing its aesthetics.

[0088] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0089] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
