[0031] 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.

[0032] In the description of this application, it should be understood that the terms "center", "length", "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this application.

[0033] Furthermore, the terms "first" and "second" are used 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 as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0034] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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, unless otherwise expressly limited.

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. "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.

[0036] With increasing emphasis on the development and utilization of green energy, the development of solar energy utilization technology, represented by the photovoltaic industry, is accelerating. Currently, photovoltaic equipment is typically used in relatively open ground or rooftop locations. However, during thunderstorms, open ground and rooftops are frequently struck by lightning. Therefore, reliable lightning protection structures are urgently needed to prevent damage to photovoltaic equipment from lightning strikes. Thus, how to solve the problem of photovoltaic equipment being easily damaged by lightning strikes due to the lack of reliable lightning protection structures has become a pressing issue for those skilled in the art. To address these problems, this application provides a photovoltaic sunshade (as shown in Figure 1).

[0037] Referring to Figure 1, the photovoltaic shading canopy 1000 of this embodiment includes photovoltaic modules 200 and a frame structure 100. The frame structure 100 includes multiple frame components 10 and multiple column components 30. The frame components 10 are used to place the photovoltaic modules 200. The upper end of each column component 30 is used to connect two adjacent frame components 10, and the lower end is provided with a grounding member 34. The grounding member 34 is electrically connected to the column component 30 and is used for grounding.

[0038] A photovoltaic (PV) awning 1000 is a building structure combining photovoltaic power generation technology and shading function, applicable to residential, commercial buildings, parking lots, and other locations. The PV awning 1000 converts solar energy into electrical energy while providing sun protection for users. It can be constructed independently or integrated with various buildings, such as on open balconies, rooftops, courtyards, or garages. In this application, the PV awning 1000 includes photovoltaic modules 200 and a frame structure 100. The photovoltaic modules 200 effectively collect solar energy and convert it into electrical energy, supplying power to nearby buildings or feeding it back into the connected power grid. The photovoltaic modules 200 can be electrically connected to external energy storage devices, which can store the electrical energy generated by the photovoltaic modules 200 and power loads such as household appliances and portable devices. The energy storage devices and photovoltaic modules 200 can be directly connected via cables or through intermediate devices such as junction boxes or combiner boards. It should be noted that in some embodiments, the energy storage module can be a lithium-ion battery, a lead-acid battery, or other types of rechargeable batteries. Meanwhile, due to the large area of ​​the photovoltaic modules 200, the photovoltaic shading canopy 1000 can also provide users with convenient shading and cooling, thereby reducing cooling needs and improving the comfort of the living or working environment. The frame structure 100 can improve the structural strength of the entire photovoltaic shading canopy 1000. The frame structure 100 is made of metal materials, including but not limited to aluminum, iron, steel, or aluminum alloys. After the photovoltaic modules 200 are struck by lightning, their own lightning current can be conducted to the frame structure 100 made of metal materials.

[0039] Specifically, the frame structure 100 of the photovoltaic awning 1000 includes multiple frame components 10 and multiple column components 30. The frame components 10 primarily support the upper structure of the photovoltaic awning 1000 and ensure its stability and durability. The frame components 10 are structures within the frame structure 100 used to encapsulate and fix the photovoltaic modules 200. The periphery of the photovoltaic modules 200 can be connected to the frame components 10, thereby ensuring the stability of the photovoltaic modules 200 within the frame structure 100. The frame components 10 can be made of high-strength, corrosion-resistant materials, such as aluminum alloy, to meet the long-term outdoor usage requirements of the frame structure 100. The column components 30 are structures used to fix and support the entire frame structure 100. The number of column components 30 can be four, six, or eight, etc. When there are four column components 30, the four column components 30 are respectively located at the four corners of the frame components 10, thereby achieving stable support for the frame components 10. The column assembly 30 can be made of metal materials such as steel and aluminum alloy to ensure that the column assembly 30 has sufficient load-bearing capacity and stability, while ensuring that the lightning current on the frame assembly 10 can be conducted to the column assembly 30.

[0040] Specifically, the lower end of the support column assembly 30 is also provided with a grounding component 34 electrically connected to the support column assembly 30. The lightning current conducted to the support column assembly 30 can be conducted to the grounding component 34 at the lower end of the support column assembly 30. Since the grounding component 34 is in contact with the ground, the lightning current will eventually be conducted to the ground through the grounding component 34, thereby avoiding excessive accumulation of lightning current on the photovoltaic sunshade 1000 and preventing damage to the various components of the photovoltaic sunshade 1000.

[0041] In some embodiments, referring to Figure 1, the column assembly 30 includes a column 31 and a base plate 32 connected to the lower end of the column 31. The base plate 32 is used to connect to the ground, and one end of the grounding member 34 is connected to the base plate 32, while the other end extends into the ground.

[0042] Specifically, the column 31 is the supporting structure in the column assembly 30. The cross-sectional dimension of the base plate 32 is larger than that of the column 31. Compared to the structure where the column 31 is directly connected to the surface to be fixed, the contact area between the column assembly 30 and the surface to be fixed is larger, thereby improving the stability of the frame structure 100 when installed on the surface to be fixed. In one example, the base plate 32 can be connected to the surface to be fixed using either a detachable or non-detachable connection method. In another example, the base plate 32 may not be connected to the surface to be fixed; in this case, the base plate 32 only bears the load on the surface to be fixed.

[0043] In some embodiments, referring to Figures 1 and 2, the grounding element 34 includes a screw 341 and a wire 342. The screw 341 is mounted on the base plate 32 and extends into the ground. The wire 342 connects to the screw 341 and is buried underground.

[0044] Specifically, the screw 341, installed on the base plate 32 and extending into the ground, can conduct the lightning current on the grounding component 34 to the ground. Since the grounding effect of the grounding component 34 is related to the equivalent resistance of its grounding end, even with a constant volume of the portion of the grounding component 34 extending into the ground, the equivalent resistance of the grounding end of the grounding component 34 will vary under different soil conditions, meaning the grounding effect of the grounding component 34 will differ. Therefore, in this application, the end of the screw 341 extending below the ground is also connected to a conductor 342. The length of the conductor 342 can be determined according to different soil conditions, thereby achieving the optimal lightning protection effect of the entire grounding component 34.

[0045] In some embodiments, referring to Figures 1 to 3, the column assembly 30 further includes an adapter 33 mounted on the upper end of the column 31. Adjacent frame assemblies 10 are connected via the adapter 33 so that multiple frame assemblies 10 surround a first space 110. The photovoltaic awning 1000 also includes a crossbeam assembly 20. The opposite ends of the crossbeam assembly 20 are respectively connected to two opposite frame assemblies 10, dividing the first space 110 into multiple second spaces 120, in which the photovoltaic modules 200 are mounted.

[0046] It is understandable that adjacent frame components 10 and adapter 33 are joined together using a non-detachable connection method, thereby improving the connection strength between the frame components 10 and adapter 33 and enhancing the stability of the frame structure 100. The non-detachable connection method includes, but is not limited to, welding or bonding. Alternatively, adjacent frame components 10 and adapter 33 can also be joined together using a detachable connection method, facilitating assembly and disassembly of the frame components 10 and adapter 33. The detachable connection method includes, but is not limited to, bolt connections or snap-fit ​​connections.

[0047] Specifically, the crossbeam assembly 20 is a structure in the frame structure 100 that serves to strengthen and support the structure. The crossbeam assembly 20 connects two opposing frame assemblies 10 to form a stable support structure, thereby facilitating more stable mounting of the photovoltaic modules 200. Specifically, the crossbeam assembly 20 can divide the first space 110 into multiple second spaces 120, allowing the photovoltaic modules 200 to be independently installed and supported within the second spaces 120. This not only improves the stability of the photovoltaic awning 1000 but also more effectively utilizes the overall space enclosed by the frame assemblies 10 (i.e., the first space 110), maximizing the number of photovoltaic modules 200 that can be installed and increasing the power generation capacity of the photovoltaic awning 1000.

[0048] In some embodiments, referring to Figures 1 to 4, the photovoltaic module 200 includes a photovoltaic element 230. The photovoltaic element 230 includes a photovoltaic panel 2301 and a connector 2305 extending from the photovoltaic panel 2301. The connectors 2305 of all photovoltaic modules 200 within the same second space 120 extend toward the same beam assembly 20 or the same frame assembly 10 and are electrically connected by an electrical connection assembly 400, which extends from the second space 120 into the cavity 1111 of the frame assembly 10 connected to either end of the beam assembly 20 and extends to the cavity 305 of the column assembly 30.

[0049] Specifically, the electrical connection assembly 400 can transfer electrical energy to an external device, which may be an energy storage device capable of storing electrical energy. For the same second space 120, the connector 2305 extends toward the same beam assembly 20 or the same frame assembly 10; that is, the connector 2305 may extend toward the same beam assembly 20, or the connector 2305 may extend toward the frame assembly 10 opposite to the beam assembly 20 in the second direction (the Y-axis direction as shown in FIG1). This application describes the connector 2305 of the same second space 120 facing the same beam assembly 20. Thus, the connectors 2305 are arranged sequentially in the first direction (the X-axis direction as shown in FIG1), and all connectors 2305 are electrically connected to the same electrical connection assembly 400. The electrical connection methods include, but are not limited to, series connection, parallel connection, and series-parallel connection. This application describes the connectors 2305 within the same second space 120 connected in series with the electrical connection assembly 400. After the electrical connection component 400 is connected to the connector 2305, it can pass through the cavity 1111 of any of the frame components 10 connected to both ends of the crossbeam 21, that is, the electrical connection component 400 can enter the cavity 1111 of any frame component 10 extending along the second direction. The electrical connection component 400, once inside the cavity 1111, can extend within the cavity 1111 and then enter the cavity 305 of any of the column components 30. In other words, in this application, the electrical connection component 400, once inside the cavity 1111, can extend within the cavity 1111 and enter any one of the four column components 30, then exit from the lower end of the column component 30 and connect electrically to an external device.

[0050] In the photovoltaic shading canopy 1000 of this application, all connectors 2305 within the same second space 120 extend in one direction, that is, connectors 2305 within the same second space 120 can be connected to the electrical connection component 400 on the same side, avoiding the need for a longer electrical connection component 400 to connect connectors 2305 on opposite sides, simplifying the arrangement of the electrical connection components 400, reducing the number of electrical connection components 400 used, thereby reducing the line resistance and heat generation of the electrical connection components 400, and reducing the energy consumption of the photovoltaic shading canopy 1000. Furthermore, the electrical connection component 400 extends from the second space 120 into the cavity 1111 and the empty cavity 305. On the one hand, the cavity 1111 and the empty cavity 305 provide a accommodating space and installation path for the electrical connection component 400, making the wiring of the electrical connection component 400 consistent with the frame structure 100, thus reducing wiring complexity. On the other hand, it can prevent the electrical connection component 400 from being exposed to the external environment, avoid wear and tear on the electrical connection component 400, improve the service life of the electrical connection component 400, and reduce the risk of electric shock or fire caused by damage to the electrical connection component 400. It also improves the neatness and aesthetics of the photovoltaic sunshade 1000.

[0051] In some embodiments, referring to Figures 1, 5, and 6, the frame assembly 10 includes a frame 11. The frame 11 includes a frame body 111 and a receiving element 51 connected to the frame body 111. The photovoltaic shading canopy 1000 also includes a drainage assembly 50, which includes a receiving element 51 and a first guide element 53. The first guide element 53 is used to connect and communicate at least one of the receiving elements 51 of two adjacent frame assemblies 10. The first guide element 53 communicates with the opening at the upper end of the column 31. The side wall at the lower end of the column 31 is provided with a drain hole 3031. The receiving element 51 is used to receive fluid and guide the fluid to flow to the first guide element 53. The first guide element 53 is used to guide the inflowing fluid to the cavity 305 of the column 31. The drain hole 3031 is used to discharge the fluid in the cavity 305 of the column 31.

[0052] Specifically, the drainage component 50 is a component in the photovoltaic shading canopy 1000 used to drain rainwater, prevent water from accumulating on the photovoltaic module 200, thereby extending the service life of the photovoltaic shading canopy 1000 and improving its power generation. The drainage component 50 includes a receiving element 51 and a first guide element 53. In the thickness direction of the photovoltaic module 200, rainwater seeping below the photovoltaic module 200 can flow into the receiving element 51 of the drainage component 50 inside the frame 11 through the gap between the frame assembly 10 and the photovoltaic module 200. The first guide element 53 communicates with the opening at the upper end of the column 31 of the column assembly 30 to guide the water flowing in from the receiving elements 51 of the two adjacent frame assemblies 10 into the cavity 305 of the column 31. The side wall at the lower end of the column 31 is provided with a drainage hole 3031, which is used to drain the liquid guided into the cavity 305 of the column 31 by the first guide element 53. The frame structure 100 of the photovoltaic sunshade 1000 discharges the liquid that seeps into the interior of the photovoltaic sunshade 1000 into the cavity 305 of the column 31 through the drainage component 50. The liquid that enters the cavity 305 of the column 31 will eventually be discharged to the outside of the photovoltaic sunshade 1000 through the drainage hole 3031 connected to the cavity 305.

[0053] In some embodiments, referring to Figures 1, 2, 5, and 6, the first flow guide 53 includes a connecting plate 531, a first sealing plate 533, and a second sealing plate 535. The connecting plate has a through hole 5311 for connecting the flow receiving parts 51 of two adjacent frame assemblies 10. The through hole 5311 connects to the cavity 305 of the column 31. The first sealing plate 533 is disposed on the connecting plate 531 and is used to connect with the frame bodies 111 of two adjacent frame assemblies 10 to seal the gap between the frame bodies 111 of the two adjacent frame assemblies 10. The second sealing plate 535 is disposed on the connecting plate 531 and is used to connect with two adjacent flow receiving parts 51 to seal the gap between the two adjacent flow receiving parts 51.

[0054] Specifically, the first guide member 53 includes a connecting plate 531 with a through hole 5311, a first sealing plate 533, and a second sealing plate 535. The first guide member 53 connects and communicates with the receiving members 51 of two adjacent frame assemblies 10, meaning water from the receiving members 51 of the two adjacent frame assemblies 10 flows into the first guide member 53. The through hole 5311 on the connecting plate 531 of the first guide member 53 communicates with the opening at the upper end of the column 31 of the column assembly 30, so as to guide the water flowing in from the receiving members 51 of the two adjacent frame assemblies 10 into the cavity 305 of the column 31. A drain hole 3031 is provided on the side wall at the lower end of the column 31, and the drain hole 3031 is used to drain the liquid introduced into the cavity 305 of the column 31 by the first guide member 53. The first sealing plate 533 is disposed on the connecting plate 531 and is used to connect the frame bodies 111 of two adjacent frame assemblies 10 to seal the gap between the frame bodies 111 of the two adjacent frame assemblies 10, preventing liquid from flowing down from the gap between the frame bodies 111 of the two adjacent frame assemblies 10 and wetting the user located under the photovoltaic sunshade 1000. The second sealing plate 535 is also disposed on the connecting plate 531 and is used to connect two adjacent receiving members 51 to seal the gap between the two adjacent receiving members 51, preventing liquid from flowing down from the gap between the two adjacent receiving members 51 and wetting the user located under the photovoltaic sunshade 1000.

[0055] In some embodiments, referring to Figures 1, 4, 5, and 6, the drainage assembly 50 further includes a second flow guide 55, which is connected and communicates with the flow receiving members 51 of at least one adjacent side frame assembly 10. Alternatively, the second flow guide 55 is connected and communicates with the flow receiving members 51 of at least one adjacent side frame assembly and the flow-carrying member 215 of the beam assembly 20. The cavity 305 of the column 31 of at least one column assembly 30 is used to pass through the electrical connection assembly 400, and the flow receiving members of the two side frame assemblies 10 connected to the column assembly 30 for passing through the electrical connection assembly 400 are communicated through the second flow guide 55.

[0056] Specifically, the drainage assembly 50 also includes a second guide member 55, which is connected and communicates with the receiving member 51 of at least two adjacent frame assemblies 10. The second guide member 55 is not communicated with the opening at the upper end of the corresponding column 31, thereby preventing water in the receiving member 51 of the two adjacent frame assemblies 10 from flowing into the cavity 305 of the column assembly 30 corresponding to the second guide member 55, so as to protect the electrical connection assembly 400 in the cavity 305 of the column assembly 30.

[0057] In some embodiments, referring to Figures 1, 5, and 6, the receiving element 51 includes a receiving plate 511 and a baffle plate 513. The receiving plate 511 is disposed on the inner sidewall of the frame body 111. The baffle plate 513 is disposed at the end of the receiving plate 511 away from the frame body 111. The receiving plate 511, the inner sidewall of the frame body 111, and the baffle plate 513 together form a receiving groove 515 for receiving fluid. The two baffle plates 513 of the receiving elements 51 of two adjacent frame assemblies 10 abut against each other. A connecting plate 531 is used to connect the receiving plates 511 of two adjacent receiving elements 51. A second sealing plate 535 is used to connect with the baffle plates 513 of two adjacent receiving elements 51 to seal the gap between the two adjacent baffle plates 513.

[0058] Specifically, the receiving element 51 includes a receiving plate 511 and a baffle plate 513. The receiving plate 511 is disposed on the inner sidewall of the frame body 111 to ensure that liquid flows into the receiving element 51 along the receiving plate 511. The baffle plate 513 is disposed at the end of the receiving plate 511 away from the frame body 111 to ensure that the liquid in the receiving element 51 flows in a second direction perpendicular to the first direction. The receiving plate 511, the inner wall of the frame body 111, and the baffle plate 513 together form a receiving groove 515 for receiving fluid. The two baffle plates 513 of the receiving parts 51 of two adjacent frame assemblies 10 abut against each other. The connecting plate 531 is used to connect the receiving plates 511 of two adjacent receiving parts 51. The second sealing plate 535 is used to connect with the baffle plates 513 of two adjacent receiving parts 51 to seal the gap between the two adjacent baffle plates 513 and prevent liquid from flowing down from the gap between the two adjacent receiving parts 51 and wetting the user located under the photovoltaic shading canopy 1000.

[0059] In some embodiments, referring to Figures 1, 5, and 6, the inlet members 51 of all adjacent frame components 10 are connected and communicated through the first guide member 53 to form a main drainage path 517. Alternatively, the drainage component 50 may also include a second guide member 55, which is connected and communicated with at least one inlet member 51 of two adjacent frame components 10. The second guide member 55 is not communicated with the opening at the upper end of the corresponding column 31. The inlet member 51, the second guide member 55, and the first guide member 53 together form the main drainage path 517.

[0060] Specifically, the receiving elements 51 of all adjacent frame components 10 are connected and interconnected through the first guide element 53 to form a main drainage path 517 around the photovoltaic module 200, thereby draining all liquid that has seeped into the photovoltaic awning 1000 into the cavity 305 of the column component 30. Since the photovoltaic awning 1000 also requires external devices and systems such as external sockets, power grid systems, and energy storage systems, at least one column component 30 is required to house the circuitry. The column component 30 used to house the circuitry also needs to be protected from rainwater to prevent short circuits and other malfunctions. Therefore, the drainage assembly 50 also includes a second guide member 55, which is connected and communicates with the receiving members 51 of at least two adjacent frame assemblies 10. The second guide member 55 is not communicated with the opening at the upper end of the corresponding column 31, thereby preventing water in the receiving members 51 of the two adjacent frame assemblies 10 from flowing into the cavity 305 of the column assembly 30 corresponding to the second guide member 55, so as to protect the circuit in the cavity 305 of the column assembly 30. The receiving member 51, the second guide member 55 and the first guide member 53 together form the main drainage path 517, thereby draining all the liquid that seeps into the photovoltaic shading canopy 1000 into the cavity 305 of the column assembly 30 corresponding to the first guide member 53.

[0061] In summary, the photovoltaic sunshade 1000 of this application includes photovoltaic modules 200 and a frame structure 100. The frame structure 100 includes multiple frame components 10 and multiple column components 30. The frame components 10 are used to place the photovoltaic modules 200 and can provide sufficient support for the photovoltaic modules 200 to ensure that the photovoltaic modules 200 can operate normally and that the lightning current on the photovoltaic modules 200 can be conducted to the frame components 10. The upper end of each column component 30 is used to connect two adjacent frame components 10, and the lower end is provided with a grounding member 34, which is electrically connected to the column component 30. The lightning current on the frame components 10 can be conducted to the grounding member 34 through the column components 30, and then conducted to the ground by the grounding member 34. This application adds a reliable lightning protection structure to the photovoltaic sunshade 1000, which can prevent the photovoltaic sunshade 1000 from being damaged by lightning strikes.
