[0047] Please refer to Figure 1 and Figure 2 The photovoltaic sunshade 1000 provided by the embodiments of the present application includes a frame structure 100 and an inverter assembly 900. The frame structure 100 includes a plurality of frame assembly 10 and a plurality of support devices 1001. The upper end of the support device 1001 is used to connect the frame assembly 10, and the lower end is connected to the surface to be fixed through a connecting piece.

[0050] The inverter assembly 900 is a converter capable of converting direct current into constant frequency and constant voltage or adjustable frequency and adjustable voltage alternating current (generally 220V, 50Hz sine wave). In the present application, the photovoltaic assembly 200 converts solar energy into electrical energy, which is transmitted to the inverter assembly 900 connected to the photovoltaic assembly 200. The inverter assembly 900 is capable of converting the direct current (DC) generated by the photovoltaic assembly 200 into alternating current (AC) and outputting the alternating current to at least one of the electrical equipment 820, the external device 840 or the power grid 860. That is, the inverter assembly 900 can output alternating current to any one of the electrical equipment 820, the external device 840 or the power grid 860, the inverter assembly 900 can output alternating current to any two of the electrical equipment 820, the external device 840 or the power grid 860, and the inverter assembly 900 can output alternating current to the electrical equipment 820, the external device 840 and the power grid 860 at the same time.
[0051] In one aspect, the inverter assembly 900 is capable of converting the direct current generated by the photovoltaic assembly 200 into alternating current and outputting the alternating current to the electrical equipment 820. The electrical equipment 820 is a device installed on the photovoltaic sunshade 1000. Preferably, the electrical equipment 820 is installed on the side of the frame structure 100 facing the surface to be fixed, so as to avoid direct contact with rainwater or other liquids, thereby prolonging the service life of the electrical equipment 820. The electrical equipment 820 can utilize the electrical energy generated by the photovoltaic assembly 200 to realize functions such as lighting, heat dissipation, voice playing, audio playing or projection, thereby improving the multifunctionality of the photovoltaic sunshade 1000. In some embodiments, the electrical equipment 820 includes at least one of a lighting module, a heat dissipation module, a voice playing device, an audio playing device, a television and a projection module. The lighting module can provide lighting function for the photovoltaic sunshade 1000, meeting the lighting demand at night or in insufficient light; the heat dissipation module can include air conditioners or fans, which can be used to reduce the temperature of the photovoltaic sunshade 1000; the voice playing device includes but is not limited to a loudspeaker, a radio receiver and the like, which is used to play voice information only; the audio playing device includes but is not limited to a television, a display and the like capable of playing audio signals; the projection module is used to project information, images or videos to a specified surface for users to watch.
[0052] In another aspect, the inverter assembly 900 is capable of converting the direct current generated by the photovoltaic assembly 200 into alternating current and outputting the alternating current to the external device 840. The external device 840 is a device that does not belong to the structure of the photovoltaic sunshade 1000 itself. For example, the photovoltaic sunshade 1000 is usually placed in the courtyard of a user, and the external device 840 can be a household appliance in the user's house, including but not limited to a computer, a refrigerator, a washing machine, and the like. The inverter assembly 900 is capable of converting the direct current generated by the photovoltaic assembly 200 into alternating current and outputting the alternating current to the external device 840, thereby meeting the household power demand.
[0053] In another aspect, the inverter assembly 900 is capable of converting the direct current generated by the photovoltaic assembly 200 into alternating current and outputting the alternating current to the external device 840. The external device 840 is a device that does not belong to the structure of the photovoltaic sunshade 1000 itself. For example, the photovoltaic sunshade 1000 is usually placed in the courtyard of a user, and the external device 840 can be a household appliance in the user's house, including but not limited to a computer, a refrigerator, a washing machine, and the like. The inverter assembly 900 is capable of converting the direct current generated by the photovoltaic assembly 200 into alternating current and outputting the alternating current to the external device 840, thereby meeting the household power demand.
[0054] In addition, the inverter assembly 900 is also used to convert the alternating current from the power grid 860 through the grid-connected bus into direct current and store the direct current into the energy storage battery. For example, in the case that the electricity price of the power grid 860 is relatively low, and the electric energy generated by the photovoltaic assembly 200 is less than or equal to the electricity demand of the electrical equipment 820 and the external device 840, the power grid 860 can transmit the electric energy to the inverter assembly 900 through the grid-connected bus, and the inverter assembly 900 can convert the incoming alternating current into direct current and store it into the energy storage battery for backup.
[0055] The photovoltaic sunshade 1000 of the present application shortens the distance between the photovoltaic assembly 200 and the inverter 910 by installing the inverter assembly 900 on the support device 1001, thereby reducing the energy loss of the electric energy in the transmission process. The photovoltaic assembly 200 is directly electrically connected to the electrical equipment 820, the external device 840, or the power grid 860 through the inverter assembly 900, further reducing the loss of electric energy in the transmission process, improving the transmission efficiency of electric energy and the power generation efficiency of the photovoltaic sunshade 1000.
[0056] Please refer to Figures 1 to 3In some embodiments, the inverter assembly 900 includes an inverter 910 mounted to the support device 1001, the inverter 910 is electrically connected to the photovoltaic assembly 200 through the first electrical connection assembly 480, and the inverter 910 is connected to at least one of the electrical device 820, the external device 840, or the power grid 860 through the second electrical connection assembly 490.
[0057] Specifically, the inverter 910 is mounted to the support device 1001. In one example, the inverter 910 and the support device 1001 can be combined together by a detachable connection, including but not limited to a snap connection or a threaded connection, etc. In another example, the inverter 910 and the support device 1001 can be combined together by a non-detachable connection, including but not limited to adhesion or welding, etc. The inverter 910 can be mounted to the outer surface of any support device 1001, and the inverter 910 can also be at least partially disposed in the inner cavity 1007 of the support device 1001. The inverter assembly 900 includes the inverter 910, and the type of the inverter 910 includes but is not limited to a string inverter, a micro-inverter, and a distributed inverter, etc., which is not limited in the present application. The inverter 910 can be one or multiple. A single inverter 910 can be electrically connected to one or multiple photovoltaic assemblies 200.
[0058] Further, the inverter 910 of the present application is a micro-inverter. Each micro-inverter is connected to one photovoltaic module, thereby performing independent Maximum Power Point Tracking (MPPT) control on each photovoltaic module. The photovoltaic canopy 1000 includes one or multiple photovoltaic modules, and one photovoltaic module can include one or multiple photovoltaic assemblies 200. The number of photovoltaic assemblies 200 included in different photovoltaic modules can be the same or different. The output power of the photovoltaic assembly 200 will change with the change of environmental conditions (such as light intensity and temperature). Under different light intensity and temperature conditions, the output voltage and current of different photovoltaic assemblies 200 will also change. The micro-inverter can continuously monitor the output voltage and current of the photovoltaic module, and dynamically adjust the working state inside the micro-inverter, track and find the Maximum Power Point (MPP) of the photovoltaic module under the current conditions, so as to ensure that the photovoltaic module is always close to or works at the maximum power point. In this way, the power output of the photovoltaic canopy 1000 can be maximized, and the power generation efficiency of the photovoltaic canopy 1000 can be improved.
[0059] The inverter 910 is electrically connected with the photovoltaic assembly 200 through the first electrical connection assembly 480, and the electrical connection mode includes but is not limited to series connection, parallel connection or a combination of both. The first electrical connection assembly 480 can be a wire, a joint, a connector or other electrical connection assembly suitable for transmitting electrical energy. The electrical energy generated by the photovoltaic assembly 200 can be directly transmitted to the inverter 910 through the first electrical connection assembly 480. The inverter 910 efficiently converts the electrical energy (direct current) generated by the photovoltaic assembly 200 into usable alternating current, thereby improving the power generation efficiency of the photovoltaic sunshade 1000.
[0060] The inverter 910 is connected with at least one of the electrical equipment 820, the external equipment 840 or the power grid 860 through the second electrical connection assembly 490, and the electrical connection mode includes but is not limited to series connection, parallel connection or a combination of both. The second electrical connection assembly 490 can be a wire, a joint, a connector or other electrical connection assembly suitable for transmitting electrical energy. The second electrical connection assemblies 490 connected with the electrical equipment 820, the external equipment 840 or the power grid 860 respectively can be the same or different. The alternating current converted by the inverter 910 is transmitted to at least one of the electrical equipment 820, the external equipment 840 or the power grid 860 through the second electrical connection assembly 490 without other complex transmission processes, thereby improving the transmission efficiency of electrical energy.
[0061] Please refer to Figures 1 to 3 In some embodiments, the plurality of frame assemblies 10 enclose the first space 110, and the photovoltaic sunshade 1000 further comprises a crossbeam assembly 20. The opposite ends of the crossbeam assembly 20 are respectively connected with the opposite two frame assemblies 10, and the crossbeam assembly 20 divides the first space 110 into a plurality of second spaces 120. The second spaces 120 are used for accommodating the photovoltaic assembly 200.
[0062] The beam assembly 20 is a structure in the frame structure 100 for reinforcement and support. The beam assembly 20 is formed by connecting two opposite edge frame assemblies 10 to form a stable support structure, thereby facilitating more stable installation of the photovoltaic assembly 200. The first space 110 can have a cross-sectional shape in the XY plane that includes, but is not limited to, regular shapes such as a square, a circle, a triangle, a rhombus, and irregular shapes. In the embodiments of the present application, only the case where the cross-sectional shape of the first space 110 is a square is described. The beam assembly 20 can divide the first space 110 into a plurality of second spaces 120, thereby enabling the photovoltaic assembly 200 to be installed and supported in the second spaces 120 in a size-fitting manner, improving the stability of the photovoltaic sunshade 1000, more effectively utilizing the overall space (i.e., the first space 110) enclosed by the edge frame assemblies 10, maximizing the number of installed photovoltaic assemblies 200, and improving the power generation capacity of the photovoltaic sunshade 1000. The second space 120 can have a cross-sectional shape in the XY plane that includes, but is not limited to, regular shapes such as a square, a circle, a triangle, a rhombus, and irregular shapes. In the embodiments of the present application, only the case where the cross-sectional shape of the second space 120 is a square is described.
[0063] Further, the photovoltaic assembly 200 in the same second space 120 can be one or multiple. The photovoltaic assembly 200 in the same second space 120 can be one layer or multiple layers, i.e., in the third direction Z, the photovoltaic assembly 200 can be multiple layers. In an embodiment, the photovoltaic assembly 200 in the same second space 120 can be arranged along the first direction X. In another embodiment, the photovoltaic assembly 200 in the same second space 120 can be arranged along the second direction Y. In this way, the photovoltaic assembly 200 is arranged regularly and compactly in the second space 120. The present application describes the case where the photovoltaic assembly 200 in the same second space 120 is one layer, and the same second space 120 includes multiple photovoltaic assemblies 200 arranged along the first direction X. In the present application, the same second space 120 includes ten photovoltaic assemblies 200.
[0064] Among them, for the photovoltaic module described above, in the embodiment where the photovoltaic module includes multiple photovoltaic components 200, the photovoltaic components 200 included in one photovoltaic module can be arbitrarily combined. In one example, one photovoltaic module can include ten photovoltaic components 200 of the same second space 120, thereby facilitating the unified management of the photovoltaic components 200 of the same second space 120. In another example, one photovoltaic module can include some photovoltaic components 200 of the same second space 120, for example, any five, so that the number of photovoltaic components 200 managed by one inverter 910 can be reduced, thereby achieving more refined control of the photovoltaic components 200 of the same second space 120. In another example, one photovoltaic module can include some photovoltaic components 200 of multiple different second spaces 120, for example, in Figure 2 In the embodiment, one photovoltaic module can be connected to four photovoltaic assemblies 200 arranged along the first direction X, so that a more flexible connection method between the photovoltaic assemblies 200 and the inverter 910 can be achieved.
[0065] See also Figures 1 to 3 In some embodiments, the first electrical connection assembly 480 at least partially penetrates into the inner cavity 1007 of the support device 1001.
[0066] Specifically, after the first electrical connection assembly 480 is electrically connected to the photovoltaic assembly 200, the first electrical connection assembly 480 can at least partially extend into the inner cavity 1007 of the support device 1001 provided with the inverter assembly 900 and connect to the inverter assembly 900. At least partially penetrating into the inner cavity 1007 of the support device 1001 means that after the first electrical connection assembly 480 is electrically connected to the photovoltaic assembly 200, it can be directly routed in the external environment and then enter the inner cavity 1007 of the support device 1001. Alternatively, the first electrical connection assembly 480 can enter the crossbeam assembly 20 after being electrically connected to the photovoltaic assembly 200 and then extend into the inner cavity 1007 of the support device 1001. Alternatively, the first electrical connection assembly 480 can enter the frame assembly 10 after being electrically connected to the photovoltaic assembly 200 and then extend into the inner cavity 1007 of the support device 1001. Furthermore, the above situations may be superimposed, that is, after the first electrical connection component 480 is electrically connected to the photovoltaic component 200, it enters the external environment, at least one of the beam component 20 and the frame component 10, and then passes through the inner cavity 1007 of the support device 1001. Here, entering the beam component 20 can mean entering the interior of the beam component 20 or entering the accommodation space (such as the current-carrying groove 575 below) where the beam component 20 communicates with the external environment, and entering the frame component 10 can mean entering the interior of the frame component 10 or entering the accommodation space (such as the current-carrying groove 575 below) where the frame component 10 communicates with the external environment.
[0067] The inner cavity 1007 of the support device 1001 provides a space for the first electrical connection assembly 480 to be installed and to be arranged in line with the frame structure 100, which reduces the complexity of the wiring and avoids the first electrical connection assembly 480 from being exposed to the external environment, thus avoiding the first electrical connection assembly 480 from being damaged and improving the service life of the first electrical connection assembly 480. In addition, the risk of electric shock or fire caused by the damage of the first electrical connection assembly 480 is reduced, and the appearance of the photovoltaic sunshade 1000 is improved.
[0068] Referring to Figures 1 to 3 In some embodiments, the second electrical connection assembly 490 is at least partially arranged in the inner cavity 1007 of the support device 1001.
[0069] Specifically, after the second electrical connection assembly 490 is electrically connected with the inverter assembly 900, the second electrical connection assembly 490 is at least partially arranged in the inner cavity 1007 of the support device 1001 in which the inverter assembly 900 is arranged, and is connected with at least one of the electrical equipment 820, the external equipment 840 or the power grid 860.
[0070] The inner cavity 1007 of the support device 1001 provides a space for the second electrical connection assembly 490 to be installed and to be arranged in line with the frame structure 100, which reduces the complexity of the wiring and avoids the second electrical connection assembly 490 from being exposed to the external environment, thus avoiding the second electrical connection assembly 490 from being damaged and improving the service life of the second electrical connection assembly 490. In addition, the risk of electric shock or fire caused by the damage of the second electrical connection assembly 490 is reduced, and the appearance of the photovoltaic sunshade 1000 is improved.
[0071] Referring to Figures 1 to 3 In some embodiments, the inverter assembly 900 further comprises a protection member 930. The inverter 910 comprises a housing body 911, a fixing member 913 and an electrical connecting member 915. The housing body 911 is provided with an interface, and the protection member 930 is movably connected to the housing body 911 and covers the interface. The fixing member 913 is arranged on the housing body 911 and is used to connect the housing body 911 to the support device 1001. The electrical connecting member 915 is arranged in the housing body 911 and is electrically connected with the second electrical connection assembly 490.
[0072] The protector 930 is used to protect the elements of the inverter 910. The material of the protector 930 can be plastic or metal, etc. When the material of the protector 930 is plastic, the insulation performance of the protector 930 is good, the cost is low, and the weight is light. When the material of the protector 930 is metal, the strength of the protector 930 is high, the wear resistance is good, and the service life is long. The connection mode of the movable connection of the protector 930 includes but is not limited to hinging, shafting, and threaded connection, etc.
[0073] The shell body 911 is a structure used to install other elements of the inverter 910 and to accommodate the other elements inside the shell body 911. The cross-sectional shape of the shell body 911 can be but is not limited to a circle, an ellipse, a rectangle, or other polygons, etc. The cross-sectional shape of the shell body 911 of the present application is a rectangle. The material of the shell body 911 can be plastic or metal, etc. When the material of the shell body 911 is plastic, the insulation performance of the shell body 911 is good, the cost is low, and the weight is light. When the material of the shell body 911 is metal, the strength of the shell body 911 is high, the wear resistance is good, and the service life is long. The fixing member 913 is used to connect the shell body 911 to the support device 1001. The fixing member 913 includes but is not limited to a buckle, a bolt, etc. The support device 1001 can be provided with a matching member matched with the fixing member 913. In some embodiments, the fixing member 913 can be a bolt, and the matching member can be a nut or other structure capable of being connected with the bolt.
[0074] The interface is used to connect the first electrical connection assembly 480. The electrical energy generated by the photovoltaic assembly 200 enters the inverter 910 through the first electrical connection assembly 480 via the interface. The inverter 910 converts the electrical energy from direct current to alternating current and then outputs to at least one of the electrical equipment 820, the external equipment 840, or the power grid 860 via the second electrical connection assembly 490 connected with the electrical connection member 915, thereby realizing the conversion and transmission of the electrical energy.
[0075] Please refer to Figures 1 to 3 In some embodiments, the plurality of support devices 1001 includes a plurality of column assemblies 30. The upper end of the column assembly 30 is used to connect two adjacent frame assemblies 10, and the lower end is used to be connected with the surface to be fixed. The inverter assembly 900 is installed in one of the plurality of column assemblies 30.
[0076] The column assembly 30 is a structure for fixing and supporting the whole frame assembly 10 and the beam assembly 20. In some embodiments of the present application, when the first space 110 has a square cross-sectional shape, the column assembly 30 can include four column assemblies 30, each of which is arranged at a corner of the square, so as to achieve stable support for the frame assembly 10. Moreover, the column assembly 30 connects two adjacent frame assemblies 10, so as to form a stable support structure for the frame assemblies 10. For example, the column assembly 30 can be made of steel, aluminum alloy, concrete, etc., so as to ensure that the column assembly 30 has sufficient load-bearing capacity and better stability, thereby ensuring the safety and reliability of the photovoltaic sunshade 1000 during long-term use.
[0077] The inverter assembly 900 is installed in one of the column assemblies 30, i.e., in the present application, the inverter assembly 900 can be installed in any one of the four column assemblies 30. Compared with the case where the inverter 910 is installed in an external environment outside the photovoltaic sunshade 1000, the inverter assembly 900 installed in the column assembly 30 is closer to the photovoltaic assembly 200, which can reduce the length of the first electrical connection assembly 480 between the photovoltaic assembly 200 and the inverter 910, reduce the line resistance in the process of electrical energy transmission, and reduce the loss in the process of electrical energy transmission.
[0078] Please refer to Figures 1 to 3 In some embodiments, the two adjacent frame assemblies 10 include a first frame assembly 101 and a second frame assembly 103; the column assembly 30 includes a column 31, a bottom plate 32 installed at the lower end of the column 31, and an adapter 33 installed at the upper end of the column 31. The column 31 is provided with a cavity 305 penetrating through the upper end surface and the lower end surface thereof, and the inner cavity 1007 of the support device 1001 includes the cavity 305. The bottom plate 32 is used to be connected with the surface to be fixed. The adapter 33 connects the first frame assembly 101 and the second frame assembly 103.
[0079] In some embodiments, the column 31 is a structure for supporting the column assembly 30. In one example, the column 31 has a fixed length. In another example, the column 31 is a telescopic structure, for example, the column 31 can include at least two sub-columns, which are telescopically connected together, so that the user can adjust the distance between the frame assembly 10 and the surface to be fixed according to the specific use requirements.
[0080] In some embodiments of the present application, the cross-sectional dimension of the bottom plate 32 is larger than that of the column 31, so that the contact area between the column assembly 30 and the surface to be fixed is larger than that between the column 31 and the surface to be fixed, thereby improving the stability of the frame structure 100 installed on the surface to be fixed. In one example, the bottom plate 32 can be combined with the surface to be fixed in a detachable or non-detachable manner. In another example, the bottom plate 32 can not be connected to the surface to be fixed, in which case the bottom plate 32 is only supported on the surface to be fixed.
[0081] In some embodiments, the assembly steps of the frame structure 100 can be as follows: first, connecting the adapter 33 to the upper end of the column 31; then, connecting the adjacent first and second frame assemblies 101 and 103 to the adapter 33; subsequently, connecting the crossbeam assembly 20 to the opposite two frame assemblies 10; and finally, connecting the bottom plate 32 to the lower end of the column 31 and to the surface to be fixed, thereby completing the assembly of the frame structure 100. It should be understood that the assembly steps of the frame structure 100 in the above-described embodiments are only exemplary, and in other embodiments, the assembly steps of the frame structure 100 can also include other forms, which are not described one by one here.
[0082] In some embodiments, the first and second frame assemblies 101 and 103 are combined with the adapter 33 in a non-detachable manner, so as to improve the connection strength between the frame assemblies 10 and the adapter 33 and the stability of the frame structure 100. The non-detachable connection manner includes, but is not limited to, welding or bonding, etc. In other embodiments, the first and second frame assemblies 101 and 103 are combined with the adapter 33 in a detachable manner, so as to facilitate the assembly and disassembly between the frame assemblies 10 and the adapter 33. The detachable connection manner includes, but is not limited to, bolt connection or buckle connection, etc.
[0083] Please refer to Figure 2 , Figure 4 and Figure 5 In some embodiments, the crossbeam assembly 20 of the photovoltaic sunshade 1000 includes a crossbeam 21, which includes a crossbeam body 211 and a fluid-carrying member 57 arranged on the opposite sides of the crossbeam body 211.
[0084] It should be noted that the structure of the crossbeam assembly 20 in the present embodiment is substantially the same as that of the frame assembly 10 in the above-described embodiments, and therefore the specific structure of the crossbeam assembly 20 in the present embodiment can refer to the structure of the frame assembly 10 described above, which is not described repeatedly here.
[0085] It can be understood that the beam body 211 can be connected to the second side wall 1115 of the frame 11 of the first frame assembly 101 and the second side wall 1115 of the frame 11 of the third frame assembly 105 through the beam joint 213; or, the beam body 211 can be connected to the second side wall 1115 of the frame 11 of the second frame assembly 103 and the second side wall 1115 of the frame 11 of the fourth frame assembly 107 through the beam joint 213, and the second side wall 1115 is one side wall of the second space 108.
[0086] Specifically, in some embodiments, when the current-carrying member 57 receives fluid, the current-carrying member 57 can guide the received fluid to the flow-receiving member 51 through the second flow guide member 55, and then the flow-receiving member 51 can guide the received fluid to the first flow guide member 53, and the fluid flows into the cavity 305 of the column 31 through the through hole 5311 on the first flow guide member 53 and the opening at the upper end of the column 31 corresponding to the first flow guide member 53, and then flows out of the column 31 through the water outlet 307 on the column 31. In this way, the fluid can be prevented from accumulating on the surface of the photovoltaic module 200, avoiding the fluid from blocking sunlight, thereby on the one hand, the light absorption rate of the photovoltaic module 200 can be improved, the energy output of the photovoltaic sunshade 1000 is ensured, and the power generation efficiency is improved; on the other hand, the photovoltaic module 200 can be prevented from being soaked by the fluid, causing the photovoltaic module 200 to age, and the fluid can be prevented from penetrating into the interior of the photovoltaic module 200, thereby prolonging the service life of the photovoltaic module 200. In addition, compared with the current-carrying member 57 directly discharging the received fluid to the surface to be fixed, the current-carrying member 57 guiding the fluid to flow to the flow-receiving member 51 can also prevent the fluid from directly impacting the surface to be fixed or other objects, thereby reducing the splashing of water and water erosion, and reducing the probability that the area below the photovoltaic module 200 is adversely affected by the fluid.
[0087] Please refer to Figures 3 to 5 In some embodiments, the frame assembly 10 further comprises a first flow guide member 53 and a second flow guide member 55, the first flow guide member 53 is connected to and communicates with the flow-receiving members 51 of at least two adjacent frame assemblies 10, and communicates with the cavity 305 of the column assembly 30, the second flow guide member 55 is not provided with a through hole 5311, the second flow guide member 55 is connected to and communicates with the flow-receiving members 51 of the remaining two adjacent frame assemblies 10, and the flow-receiving member 51, the second flow guide member 55, the first flow guide member 53 and the column assembly 30 together form a drainage main road 517. The current-carrying member 57 is connected to and communicates with the flow-receiving member 51 through the first flow guide member 53 or the second flow guide member 55.
[0088] Specifically, the flow receiving member 51 is used to receive fluid flowing to the frame assembly 10 and the photovoltaic assembly 200. The flow receiving member 51 includes a flow receiving plate 511 and a flow blocking plate 513. The flow receiving plate 511 is arranged on the inner side wall 1115 of the frame body 111. The flow blocking plate 513 is arranged on the end of the flow receiving plate 511 away from the frame body 111. The flow receiving plate 511, the inner side wall 1115 of the frame body 111 and the flow blocking plate 513 jointly define a flow receiving groove 515 for receiving fluid. The two flow blocking plates 513 of the flow receiving members 51 of two adjacent frame assemblies 10 abut each other.
[0089] The flow carrying member 57 is also used to receive fluid flowing to the cross beam assembly 20 and the photovoltaic assembly 200, and guide the fluid to flow to the first flow guiding member 53 or the second flow guiding member 55. The flow carrying member 57 includes a flow carrying plate 571 and a flow blocking plate 573. The flow carrying plate 571 is arranged on the opposite sides of the cross beam body 211 in the width direction. The flow blocking plate 573 is arranged on the end of the flow carrying plate 571 away from the cross beam body 211. The flow carrying plate 571, the side wall of the cross beam body 211 and the flow blocking plate 573 jointly define a flow carrying groove 575 for carrying fluid. The flow carrying groove 575 can guide the fluid flowing to the cross beam assembly 20 to the first flow guiding member 53 or the second flow guiding member 55. In this way, the fluid in the flow carrying member 57 can enter the flow receiving member 51, flow into the cavity 305 of the column assembly 30 through the through hole 5311 of the first flow guiding member 53, and finally be discharged to the outside through the drain port 307.
[0090] The first flow guiding member 53 includes a connecting plate 531, a first sealing plate 533 and a second sealing plate 535. The connecting plate 531 is provided with a through hole 5311 and is used to connect the flow receiving members 51 of two adjacent frame assemblies 10. The through hole 5311 is used to communicate the cavities 305 of the column assemblies 30. The first sealing plate 533 is arranged 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. The second sealing plate 535 is arranged on the connecting plate 531 and is used to connect the flow receiving members 51 of two adjacent frame assemblies 10 to seal the gap between the two adjacent flow receiving members 51. The side wall of the lower end of the column assembly 30 is provided with a drain port 307. The first flow guiding member 53 is used to guide fluid to the cavity 305 of the column assembly 30. The drain port 307 is used to discharge the fluid in the cavity 305 of the column assembly 30.
[0091] The second flow guide 55 comprises a coupling plate 551, a first blocking plate 553 and a second blocking plate 555. The coupling plate 551 is not provided with a through hole and is used to connect the flow guide plate 511 of the flow guide 51 of the adjacent two frame assembly 10. The first blocking plate 553 is arranged on the coupling plate 551 and is connected with the frame body 111 of the adjacent two frame assembly 10, so as to block the gap between the frame body 111 of the adjacent two frame assembly 10. The second blocking plate 555 is arranged on the coupling plate 551 and is connected with the flow blocking plate 513 of the adjacent two flow guide 51, so as to block the gap between the adjacent two flow guide 51.
[0092] In one example, the flow guide 51 of all adjacent two frame assembly 10 is connected and communicated through the first flow guide 53, so as to form the main drainage path 517, and the flow channel 575 serves as a branch drainage path and is communicated with the main drainage path 517. Further, the fluid flowing to the beam assembly 20 and the photovoltaic assembly 200 flows into the flow channel 575, and then the fluid flows into the flow guide 51 of the frame 11 connected with the opposite ends of the second flow guide 55 through the second flow guide 55 and enters the main drainage path 517, and the fluid flowing to the frame assembly 10 and the photovoltaic assembly 200 also flows into the flow guide 51, and the fluid in the flow guide 51 flows into the cavity 305 of the corresponding column assembly 30 through the through hole 5311 of any first flow guide 53 and then is discharged from the drain port 307. At this time, since the flow guide 51 of all adjacent two frame assembly 10 is connected and communicated through the first flow guide 53, the cavity 305 of all column assembly 30 can be used to discharge the fluid, which improves the drainage performance of the photovoltaic sunshade 1000, thereby improving the working stability of the photovoltaic sunshade 1000.
[0093] In another example, the second flow guide 55 is connected to and communicates with the flow connectors 51 of two adjacent frame assemblies 10, and the first flow guide 53 is connected to and communicates with the flow connectors 51 of one adjacent frame assembly 10. That is, only one of the four column assemblies 20 has the first flow guide 53 at the upper end, and the through hole 5311 of the first flow guide 53 communicates with the opening of the upper end of the column assembly 20, and the other three column assemblies 10 have the second flow guide 55 at the upper end, and the second flow guide 55 does not communicate with the opening of the upper end of the corresponding column assembly 20. The flow connectors 51, the second flow guide 55, and the first flow guide 53 together form the main drainage path 517, and the current-carrying member 57 serves as a branch drainage path and communicates with the main drainage path 517. Further, the fluid flowing to the beam assembly 20 and the photovoltaic assembly 200 flows into the current-carrying groove 575, then flows into the flow connector 51 of the frame 11 connected to the opposite ends of the second flow guide 55, and the fluid flowing to the frame assembly 10 and the photovoltaic assembly 200 also flows into the flow connector 51. Part of the fluid in the flow connector 51 flows into the cavity 305 of the corresponding column assembly 30 through the through hole 5311 of any first flow guide 53, and then flows out of the drain 307. Part of the fluid in the flow connector 51 passes through the second flow guide 55, and then flows into the cavity 305 of the corresponding column assembly 30 through the through hole 5311 of any first flow guide 53, and then flows out of the drain 307. In this way, the photovoltaic sunshade 1000 has a cavity 305 of one column assembly for draining fluid, which can concentrate drainage and also provide more options for the electrical connection assembly 400. The electrical connection assembly 400 can be wired in the other three column assemblies 20 without drainage.
[0094] In other examples, the upper ends of the four column assemblies 20 can correspond to two second flow guides 55 and two first flow guides 53. The two second flow guides 55 can be arranged at the two column assemblies 20 located on the diagonal line, or can be arranged at the two column assemblies 20 located on the same side. The upper ends of the four column assemblies 20 can also correspond to one second flow guide 55 and three first flow guides 53, and the second flow guide 55 can be arranged at any one of the four column assemblies 20.
[0095] Please refer to Figures 3 to 5 In some embodiments, the flow connectors 51 of the two frame assemblies 10 connected to the column assembly 30 of the first electrical connection assembly 480 of the inverter assembly 900 are connected and communicated by the second flow guide 55.
[0096] Specifically, the first electrical connection assembly 480 can extend to the cavity 305 of any one of the column assemblies 30 after entering the cavity 1111 of any one of the frame assemblies 10. Preferably, the column assembly 30 into which the first electrical connection assembly 480 enters is any one of the column assemblies 30 at the opposite ends of the frame assembly 10 into which the first electrical connection assembly 480 enters. In this way, the length of the first electrical connection assembly 480 extending in the cavity 1111 of the frame assembly 10 can be reduced, thereby reducing the amount of the first electrical connection assembly 480. The column assembly 30 in which the first electrical connection assembly 480 is arranged is connected to two frame assemblies 10, and the flow connectors 51 of the two frame assemblies 10 are connected and communicated by the second flow guide 55. The second flow guide 55 does not have the through hole 5311, and fluid cannot enter the cavity 305 of the column assembly 30 in which the first electrical connection assembly 480 is arranged. In this way, the fluid can be prevented from contacting the first electrical connection assembly 480, and electric leakage can be avoided.
[0097] Please refer to Figures 3 to 5 In some embodiments, the at least one frame assembly 10 includes at least two sub-frame assemblies 10, and the tail end of one of the at least two sub-frame assemblies 10 is connected to the head end of the other. The plurality of support devices 1001 includes at least two support column assemblies 40, the upper end of each support column assembly 40 is configured to be connected to one of the at least two sub-frame assemblies 10, and the lower end is configured to be connected to the surface to be fixed. The inverter assembly 900 is installed on one of the at least two support column assemblies 40.
[0098] The support column assembly 40 is arranged between two pairs of adjacent column assemblies 30, thereby achieving stable support of the frame assembly 10. The support column assembly 40 can be made of steel, aluminum alloy, concrete, etc., to ensure that the support column assembly 40 has sufficient load-bearing capacity and stability, thereby ensuring the safety and reliability of the photovoltaic sunshade 1000 during long-term use. The at least one frame assembly 10 includes at least two sub-frame assemblies 10 (e.g., a first sub-frame assembly 1091 and a second sub-frame assembly 1093), and the tail end of one of the at least two sub-frame assemblies 10 is connected to the head end of the other. The upper end of each support column assembly 40 is configured to be connected to one of the at least two sub-frame assemblies 10, and the lower end is configured to be connected to the surface to be fixed. That is, the support column assembly 40 can support the frame assembly 10 forming the long side of the first space 110, thereby reducing the possibility of deformation and damage of the frame assembly 10 under the action of the gravity of the photovoltaic assembly 200 and / or external load, and further improving the structural stability of the photovoltaic sunshade 1000.
[0099] The inverter assembly 900 is installed on one of the plurality of support column assemblies 40, which is located between two adjacent upright column assemblies 30. Therefore, the distance between the inverter assembly 900 installed on the support column assembly 40 and all the photovoltaic assemblies 200 is uniform, which can reduce the length difference of the first electrical connection assemblies 480 between the inverter assembly 900 and each photovoltaic assembly 200, balance the efficiency of the electrical energy transmission from each photovoltaic assembly 200 to the inverter assembly 900, and make the load of the plurality of first electrical connection assemblies 480 more balanced. In addition, compared with installing the inverter 910 externally, installing the inverter assembly 900 on the support column assembly 40 makes the inverter assembly 900 closer to the photovoltaic assemblies 200, which can reduce the length of the first electrical connection assemblies 480 between the photovoltaic assemblies 200 and the inverter 910, reduce the line resistance in the process of electrical energy transmission, and reduce the loss in the process of electrical energy transmission.
[0100] Please refer to Figures 1 to 4 In some embodiments, the support column assembly 40 includes a support column 41, a base plate 45 installed at the lower end of the support column 41, and a coupling member 43 installed at the upper end of the support column 41. The support column 41 is provided with a mounting cavity 405 penetrating through the upper end surface and the lower end surface thereof, and the inner cavity 1007 of the support device 1001 includes the mounting cavity 405. The base plate 45 is used to be connected with the surface to be fixed. The coupling member 43 is connected with one of the first sub-frame assembly 1091 and the second sub-frame assembly 1093.
[0101] The support column 41 is a structure that plays a supporting role in the support column assembly 40. In one example, the support column 41 has a fixed length. In another example, the support column 41 is a telescopic structure, so that the user can adjust the distance between the frame assembly 10 and the surface to be fixed according to the specific use requirements. It can be understood that, when the upright column assembly 30 and the support column assembly 40 are both connected with the frame assembly 10, the lengths of the upright column assembly 30 and the support column assembly 40 are the same, that is, the length of the support column 41 is the same as the length of the upright column 31.
[0102] In some embodiments of the present application, the cross-sectional dimension of the base plate 45 is greater than the cross-sectional dimension of the support column 41, so that, compared with directly connecting the support column 41 with the surface to be fixed, the contact area between the support column assembly 40 and the surface to be fixed is larger, thereby improving the stability of the installation of the frame structure 100 on the surface to be fixed. In one example, the base plate 45 can be combined with the surface to be fixed in a detachable connection manner or a non-detachable connection manner. In another example, the base plate 45 can not be connected with the surface to be fixed, and in this case, the base plate 45 is only supported on the surface to be fixed.
[0103] In some embodiments, the first sub-frame assembly 1091 comprises a first sub-frame 10911, the second sub-frame assembly 1093 comprises a second sub-frame 10931, and the assembling steps of the second frame assembly 103 and the support column assembly 40 can be as follows: firstly, connecting the coupling member 43 to the upper end of the support column 41; then, partially penetrating the coupling member 43 through the first sub-frame 10911 or the second sub-frame 10931, and connecting the first sub-frame assembly 1091 or the second sub-frame assembly 1091 to the coupling member 43; subsequently, connecting the first sub-frame assembly 1091 and the second sub-frame assembly 1093; finally, connecting the base plate 45 to the lower end of the support column 41, and connecting the base plate 45 to the surface to be fixed, thus completing the assembling of the second frame assembly 103 and the support column assembly 40. It can be understood that the assembling steps of the second frame assembly 103 and the support column assembly 40 in the above embodiments are only exemplary, and in other embodiments, the assembling steps of the second frame assembly 103 and the support column assembly 40 can also include other forms, which are not exemplified one by one here.
[0104] Referring to Figures 1 to 4 In some embodiments, the current collector 51 of the frame assembly 10 connected with the support column assembly 40 penetrating the first electrical connection assembly 480 of the inverter assembly 900 is connected and communicated with the current collector 57 through the second flow guide 55.
[0105] Specifically, after the first electrical connection assembly 480 enters the cavity 1111 of any frame assembly 10, it can extend to the mounting cavity 405 of any support column assembly 40. Preferably, the support column assembly 40 entered by the first electrical connection assembly 480 is any support column assembly 40 at the opposite ends of the frame assembly 10 entered by the first electrical connection assembly 480, so that the length of the first electrical connection assembly 480 extending in the cavity 1111 of the frame assembly 10 can be reduced, thereby reducing the amount of the first electrical connection assembly 480. The support column assembly 40 penetrating the first electrical connection assembly 480 is connected with two frame assemblies 10, the current collectors 51 of the two frame assemblies 10 are connected and communicated through the second flow guide 55, the second flow guide 55 has no through hole 5311, and fluid cannot enter the cavity 305 of the support column assembly 40 penetrating the first electrical connection assembly 480, so that the fluid can be prevented from contacting the first electrical connection assembly 480 to avoid electric leakage.
[0106] Referring to Figure 1 , Figure 2 and Figure 6In some embodiments, the photovoltaic assembly 200 comprises a photovoltaic unit 230, the photovoltaic unit 230 comprises a photovoltaic panel 2301, a junction box 2303 and a connector 2305 extending from the junction box 2303, the connectors 2305 of all photovoltaic assemblies 200 in the same second space 120 extend towards the same crossbeam assembly 20 or the same frame assembly 10 of the photovoltaic sunshade 1000 and are electrically connected by the third electrical connection assembly 410, the third electrical connection assembly 410 penetrates into the cavity 1111 of the frame assembly 10 connected with either end of the crossbeam assembly 20 from the second space 120 and extends to the inner cavity 1007 of the support device 1001 and then penetrates out from the lower end of the support device 1001.
[0107] The photovoltaic assembly 200 is a solar conversion device that converts solar energy into electrical energy. The photovoltaic assembly 200 can be a single-crystal silicon, polycrystalline silicon or thin-film solar cell and other types of solar conversion devices. Among them, the photovoltaic unit 230 is used to convert solar energy into electrical energy, the electrical connection element inside the photovoltaic unit 230 is electrically connected with the junction box 2303, the junction box 2303 can transmit the converted electrical energy from the connector 2305 of the junction box 2303 to the third electrical connection assembly 410, the third electrical connection assembly 410 then transmits the electrical energy to the external equipment 840, which can be an energy storage device capable of storing electrical energy. The photovoltaic assembly 200 is arranged on the frame structure 100, which can not only absorb sunlight to convert solar energy into electrical energy for power generation, but also cover the second space 120 to reduce sunlight from shining into the photovoltaic sunshade 1000, thereby achieving the effect of sunshade. Among them, the inside of the photovoltaic sunshade 1000 refers to the space below the photovoltaic assembly 200 and surrounded by the frame structure 100.
[0108] The cross-sectional shape of the photovoltaic member 230 in the XY plane can include, but is not limited to, regular shapes such as square, circle, triangle, and rhombus, or irregular shapes. In the embodiments of the present application, only the cross-sectional shape of the photovoltaic panel 2301 is taken as an example of a square. For the same second space 120, the joints 2305 extend towards the same beam assembly 20 or the same frame assembly 10, that is, the joints 2305 can extend towards the same beam assembly 20, or the joints 2305 can extend towards the frame assembly 10 opposite the beam assembly 20 in the second direction Y. The present application describes the joints 2305 of the same second space 120 extending towards the same beam assembly 20. In this way, the joints 2305 are arranged in sequence in the first direction X, and all the joints 2305 are electrically connected to the same third electrical connection assembly 410. The electrical connection mode includes, but is not limited to, series connection, parallel connection, and series-parallel connection. The present application describes the joints 2305 in the same second space 120 connected in series with the third electrical connection assembly 410. After the third electrical connection assembly 410 is connected to the joints 2305, it can pass through the cavity 1111 of any one frame assembly 10 connected to both ends of the beam 21, that is, the third electrical connection assembly 410 can pass into the cavity 1111 of any one frame assembly 10 extending in the second direction Y. The third electrical connection assembly 410 entering the cavity 1111 can extend in the cavity 1111 and then enter the cavity 305 of any one of the four column assemblies 30. That is, in the present application, the third electrical connection assembly 410 entering the cavity 1111 can extend in the cavity 1111 and then enter any one of the four column assemblies 30, and then pass out from the lower end of the column assembly 30 to be electrically connected to the external device 840.
[0109] All the joints 2305 in the same second space 120 extend in one direction, that is, the joints 2305 in the same second space 120 can be connected to the third electrical connection assembly 410 on the same side, avoiding the need for longer third electrical connection assemblies 410 to connect joints 2305 on different sides, allowing the third electrical connection assembly 410 to be arranged simply, reducing the amount of third electrical connection assembly 410 used, thereby reducing the line resistance and heat generation of the third electrical connection assembly 410, and reducing the energy consumption of the photovoltaic sunshade 1000. In addition, the third electrical connection assembly 410 passes from the second space 120 into the cavity 1111 and the cavity 305. On the one hand, the cavity 1111 and the cavity 305 provide accommodation space and installation path for the third electrical connection assembly 410, making the wiring of the third electrical connection assembly 410 consistent with the frame structure 100, reducing the complexity of wiring, on the other hand, it can avoid the third electrical connection assembly 410 being exposed to the external environment, avoiding wear and tear of the third electrical connection assembly 410, improving the service life of the third electrical connection assembly 410, reducing the risk of electric shock or fire caused by damage to the third electrical connection assembly 410, and on the other hand, improving the neatness and beauty of the outer surface of the photovoltaic sunshade 1000.
[0110] Please refer to Figure 1 , Figure 2 and Figure 6 In some embodiments, the third electrical connection assembly 410, the first electrical connection assembly 480 of the inverter assembly 900 and the second electrical connection assembly 490 of the inverter assembly 900 extend to the same inner cavity 1007 of the support device 1001. In this way, the third electrical connection assembly 410, the first electrical connection assembly 480 of the inverter assembly 900 and the second electrical connection assembly 490 of the inverter assembly 900 can be wired regularly, and more options can be provided for the main drainage path. The main drainage path can be drained through any column assembly 30 that does not accommodate an electrical connection assembly (any one of the first electrical connection assembly 480, the second electrical connection assembly 490 and the third electrical connection assembly 410).
