Description

Technical Field

[0001] This invention relates to the field of building engineering technology, specifically to a comprehensive adjustable-angle shading louvered photovoltaic building integrated system. Background Technology

[0002] In the construction industry, shading devices and photovoltaic power generation technology are widely used to optimize the built environment and utilize solar energy resources, respectively. However, traditional methods have some limitations.

[0003] Traditional shading devices, such as blinds and venetian blinds, are used to regulate light and temperature inside buildings. However, these devices are usually at a fixed angle and cannot adaptively adjust to the angle of sunlight, resulting in problems of excessive or insufficient sunlight. Furthermore, traditional shading devices are difficult to integrate effectively with photovoltaic technology, failing to achieve the dual functions of shading and power generation.

[0004] Traditional photovoltaic (PV) power generation systems use fixed-angle photovoltaic panels, typically installed on building rooftops or other fixed locations. This method cannot fully utilize the varying angles of solar energy, affecting power generation efficiency. Furthermore, fixed-installation PV panels are difficult to integrate seamlessly with the building's exterior, potentially compromising its aesthetics.

[0005] Therefore, it is evident that there is an urgent need for a device that integrates shading louvers and photovoltaic power generation technology into a single design, capable of adaptively adjusting the louver angle to achieve the dual functions of shading and solar power generation. This is a problem that needs to be solved in this field. Summary of the Invention

[0006] In view of the above-mentioned technical problems of existing shading devices and photovoltaic power generation technology, the purpose of this invention is to provide an integrated variable shading panel for photovoltaic devices. This shading panel integrates shading louvers and photovoltaic power generation technology, and can adaptively adjust the louver angle to achieve the dual functions of shading and solar power generation.

[0007] To achieve the above objectives, the present invention provides an integrated variable sunshade for a photovoltaic device, comprising a frame unit, a first adjustment component, a second adjustment component, and a third adjustment component. The frame unit includes a plurality of vertical rods, a plurality of longitudinal rods, and a plurality of transverse rods. The plurality of vertical rods are equidistantly distributed and their upper ends are respectively connected to the transverse rods via the third adjustment component. The upper ends of the vertical rods can rotate relative to the transverse rods via the third adjustment component to adjust the angle between adjacent vertical rods. The longitudinal rods are disposed at both ends of the transverse rods and are connected to the second adjustment component. The transverse rods can rotate relative to the longitudinal rods via the second adjustment component to adjust the angle of the transverse rods and the vertical rods on the transverse rods as a whole relative to the longitudinal rods. The longitudinal rods are provided with a first adjustment component that cooperates with a second adjustment component at the end of the transverse rods. The transverse rods can be horizontally displaced along the first adjustment component on the longitudinal rods via the second adjustment component.

[0008] Furthermore, the transverse rod is provided with a plurality of connecting holes at equal intervals for setting the third adjustment component, and a gasket is fitted inside the connecting hole.

[0009] Furthermore, the third adjustment component includes a transmission chain, a gear, a support lug, and a connecting shaft. The transmission chain is mounted on the transverse member, and one end of the connecting shaft is connected to the vertical member. The connecting shaft is symmetrically provided with support lugs. When the other end of the connecting shaft passes through the connection hole of the transverse member, it is vertically supported on the transverse member at the connection hole by the support lugs. The other end of the connecting shaft is provided with a gear, which meshes with the transmission chain on the transverse member. The gear rotates on the transmission chain, thereby driving the connecting shaft to drive the vertical member to rotate relative to the transverse member, so as to adjust the angle between the vertical member and the transverse member.

[0010] Furthermore, the lower end of the vertical rod is a frame skeleton for assembling the sunshade unit.

[0011] Furthermore, the sunshade unit includes several louvers, which are respectively disposed within the frame of the vertical rod.

[0012] Furthermore, a photovoltaic module is provided on the sunshade unit. The photovoltaic module includes a first encapsulation layer, a second encapsulation layer, and a photovoltaic cell. The first encapsulation layer and the second encapsulation layer are respectively disposed on both sides of the photovoltaic cell, forming a wrapping structure for the photovoltaic cell.

[0013] Furthermore, the second adjustment component includes a first rotating gear and a second rotating gear. The first rotating gear is disposed at both ends of the transverse member, and the second rotating gear is disposed at the end of the longitudinal member. The rotation of the second rotating gear drives the first rotating gear to adjust the angle of the transverse member relative to the longitudinal member.

[0014] Furthermore, the longitudinal member includes a central hollow layer and a first surface layer and a second surface layer located on both sides of the central hollow layer. The central hollow layer is provided with a slide rail and cooperates with a first rotating gear and a second rotating gear to form a third adjustment component. The second rotating gear and the first rotating gear are engaged and connected, and both move horizontally along the slide rail at the same time, driving the transverse member to move along the longitudinal member as a whole, so as to adjust the distance between the sunshade unit and the wall.

[0015] Furthermore, the third adjustment component is equipped with a limiting structure, which includes several limiting holes and a U-shaped limiter. The limiting holes are equidistantly distributed on the first surface layer and the second surface layer, and are connected to the intermediate hollow layer. The U-shaped limiter is inserted at two adjacent limiting holes to adjust the movement distance. The integrated variable sunshade of the photovoltaic device provided by this invention combines adjustable angle sunshade louvers with a semi-transparent photovoltaic cell module, realizing the dual functions of sunshade and solar power generation.

[0016] Secondly, through the horizontal angle adjustment mechanism, the louver unit can adjust its angle in real time according to external light and internal needs, so as to maximize the balance between shading effect and photovoltaic power generation efficiency.

[0017] In addition, the sunshade louvers can be rotated vertically around the horizontal rod by the vertical angle adjustment mechanism, so as to fully realize the sunshade and lighting effects and aesthetic effects according to the user's needs. Attached Figure Description

[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to specific illustrations.

[0029] In view of the above-mentioned technical problems of existing shading devices and photovoltaic power generation technology, the purpose of this invention is to provide a comprehensive variable shading panel for photovoltaic devices, which integrates shading louvers and photovoltaic power generation technology, and can adaptively adjust the louver angle to achieve the dual functions of shading and solar power generation.

[0030] Specifically, the integrated variable sunshade of the photovoltaic device provided by this invention, see [link to relevant documentation]. Figure 1 It includes a frame unit 100, a sunshade unit 200, and an adjustment unit composed of a first adjustment component 310, a second adjustment component 320, and a third adjustment component 330.

[0031] Further, see Figure 2 The frame assembly 100 includes several vertical rods 120, several longitudinal rods 130, and several transverse rods 110. The combination of the several vertical rods 120, several longitudinal rods 130, and several transverse rods 110 can form the support frame of the entire sunshade device for installing the sunshade unit.

[0032] The horizontal member 110 is horizontally positioned above several vertical members 120. The several vertical members 120 are equidistantly distributed and are respectively connected to the horizontal member 110 for transmission. The several vertical members 120 can be rotated relative to the horizontal member 110 to adjust the angle of the vertical member 120 relative to the horizontal member 110.

[0033] For details, see Figure 3A plurality of connecting holes 111 are provided at equal intervals on the horizontal member 110, and a gasket 112 is provided on each connecting hole 111. A plurality of vertical members 120 are distributed at equal intervals and their upper ends are connected to the connecting holes 111 of the horizontal member 110 through the third adjusting component 330. After the plurality of vertical members 120 are connected to the horizontal component 110 through the third adjusting component 330, the plurality of vertical members 120 can rotate synchronously relative to the horizontal member 110.

[0034] Further, see Figure 4 and Figure 6 The third adjustment component 330 includes a transmission chain 331, a gear 332, a support lug 334, and a connecting shaft 333.

[0035] The end face of the transverse rod 110 is provided with an elongated hole, and a transmission chain 331 is installed in the elongated hole. The transmission chain 331 is installed on the transverse rod 110 and cooperates with the second servo motor. The second servo motor can drive the transmission chain 331 to rotate.

[0036] One end of the connecting shaft 333 is connected to the vertical member 120. The connecting shaft 333 is symmetrically provided with support ear plates 334. When the other end of the connecting shaft 333 passes through the connecting hole 111 and the gasket 112 of the horizontal member 110, it is vertically supported on the horizontal member 110 at the connecting hole 111 and the gasket 112 of the horizontal member 110 by the support ear plates 334.

[0037] Meanwhile, a gear 332 is provided at the other end of the connecting shaft 333 and meshes with the transmission chain 331 on the transverse rod 110. The transmission chain 331 is driven to rotate by the second servo motor, and the gear 332 on it rotates on the transmission chain 331, thereby driving the connecting shaft 333 to drive the vertical rod 120 to rotate relative to the transverse rod 110, so as to adjust the angle of the vertical rod 120 relative to the transverse rod 110.

[0038] Furthermore, the lower end of the vertical member 120 is a frame-like skeleton for assembling the sunshade unit 200. The sunshade unit 200 includes several louvers 210, which are respectively disposed within the frame-like skeleton at the lower end of each vertical member 120.

[0039] Here, the lower frame is preferably made of lightweight and durable aluminum alloy to ensure the structural strength and durability of the louver 210.

[0040] Louver 210 and vertical rod 120 move in tandem, see Figure 5 When the vertical rod 120 rotates to its maximum value, the louver 210 is in a completely flat state, which can completely cover the gap between the vertical rods 120, thus achieving the effect of sun shading.

[0041] This solution uses a horizontal angle adjustment mechanism, allowing the 210 louvers to adjust their angle in real time according to external light and internal needs, maximizing the balance between shading effect and photovoltaic power generation efficiency.

[0042] The louvers 210 are preferably made of lightweight and sturdy materials (such as aluminum alloys) to ensure structural stability and durability.

[0043] Meanwhile, a semi-transparent photovoltaic module 220 is embedded inside or outside each louver 210, tightly integrating the louver and the photovoltaic module 220 to form an integrated appearance design that is not only aesthetically pleasing but also practical, reducing the impact on the building's appearance.

[0044] These photovoltaic modules 220 employ organic solar cell technology, allowing some sunlight to pass through while converting the remaining energy into electricity. Thus, the louvers 210 not only provide shading but also capture solar energy for power generation.

[0045] In some embodiments, the photovoltaic module 220 includes a first encapsulation layer, a second encapsulation layer, and a photovoltaic element.

[0046] The first encapsulation layer and the second encapsulation layer are respectively disposed on both sides of the photovoltaic cell, forming a wrapping structure to protect the photovoltaic cell from environmental factors such as rain, dust, and ultraviolet rays.

[0047] This solution combines adjustable-angle shading louvers with semi-transparent photovoltaic cell modules, achieving the dual functions of shading and solar power generation.

[0048] The longitudinal members 130 are distributed at both ends of the transverse members 110 and are connected to each other by the second adjustment component 320. The transverse members 110 can rotate relative to the longitudinal members 130 through the second adjustment component 320 to adjust the angle of the transverse members 110 and the vertical members 120 on the transverse members 110 relative to the longitudinal members 130.

[0049] Further, see Figure 6 The second adjustment component 320 includes a first rotating gear 321 and a second rotating gear 312. The first rotating gear 321 is disposed at both ends of the transverse rod 110, and the second rotating gear 312 is disposed at the end of the longitudinal rod 130. The second rotating gear 312 is equipped with a first servo motor, which rotates under the force of the first servo motor and drives the first rotating gear 321 to rotate, thereby adjusting the angle between the transverse rod 110 and the longitudinal rod 130.

[0050] In this scheme, the first rotating gear on the transverse rod 110 is connected to the second rotating gear 312 on the longitudinal rod 130, and the angle adjustment of the louvered sunshade relative to the longitudinal rod is achieved under the action of the first servo motor.

[0051] Further, see Figure 7 The longitudinal member 130 includes a central hollow layer 315 and a first surface layer 313 and a second surface layer 314 located on both sides of the central hollow layer 315. The central hollow layer 315 is provided with a slide rail 311, which cooperates with the first rotating gear 321 and the second rotating gear 312 to form a first adjustment component 330. The second rotating gear 312 and the first rotating gear 321 are in a meshed connection state and move horizontally along the slide rail 311 at the same time, driving the transverse member 110 to move along the longitudinal member 130 to adjust the distance between the sunshade unit 200 and the wall.

[0052] The first adjustment component 310 is equipped with a limiting structure, which includes several limiting holes 316 and a U-shaped limiter 317. The several limiting holes 316 are equidistantly distributed on the first surface layer 313 and the second surface layer 314, and are connected to the middle hollow layer 315. The U-shaped limiter 317 adjusts the movement distance between two adjacent limiting holes 316, thereby realizing the controllability of the distance between the sunshade unit 200 (or the horizontal rod 110) and the wall.

[0053] At the same time, by moving the gear 332 back along the slide rail 311 to a position closer to the wall, the destructive force of extreme weather on the sunshade can be further reduced.

[0054] The angle adjustment unit in this solution can adjust the angle of the louver segments according to the instructions of the intelligent control unit, external light, temperature and building interior requirements. This ensures the maximization of the shading effect while also guaranteeing the best solar energy collection of the photovoltaic modules, thus maximizing the balance between shading effect and photovoltaic power generation efficiency.

[0055] Through the above innovative design, this invention creatively combines adjustable-angle sunshade louvers with photovoltaic panels, achieving the following significant effects:

[0056] (1) Dual function: This system can provide shading function and adjust the louver angle to control indoor light and temperature. At the same time, it can also place photovoltaic panels inside the louvers to convert solar energy into electrical energy and realize solar power generation.

[0057] (2) Highly customizable: Users can flexibly adjust the angle of the louvers according to actual needs to meet the shading and power generation needs of different time periods and seasons, thus improving the flexibility and applicability of the system.

[0058] (3) Environmental protection and energy saving: Utilizing renewable energy such as solar power reduces dependence on traditional energy sources, lowers building energy consumption, and is environmentally friendly.

[0059] In summary, this invention achieves the dual functions of sun shading and photovoltaic power generation in the building field. Through adaptive angle adjustment, it improves the utilization efficiency of solar energy and makes a positive contribution to building energy conservation and environmental protection.
