Description

Technical Field

[0001] This utility model relates to the field of building energy conservation and renewable energy application technology, specifically to an integrated system that combines photovoltaic power generation function with building exterior shading louvers. Background Technology

[0002] Integrating photovoltaic modules with building exterior shading louvers is an effective way to achieve integrated building energy conservation and energy production. Currently, there have been some technological attempts in this field, but existing solutions still have significant shortcomings in mechanical drive, solar thermal regulation, and structural integration, failing to fully achieve a balance between function, efficiency, and reliability.

[0003] Firstly, regarding the mechanical drive structure, existing photovoltaic louver systems mostly employ decentralized drive methods (such as each louver being equipped with an independent micro-motor) or traditional linkage and chain drives. These structures suffer from problems such as complex transmission paths, poor synchronization, difficulty in withstanding large louver loads, and susceptibility to wear and jamming during long-term outdoor use. Especially for louver arrays with large lengths or a large number of louvers, there is a lack of a simple and reliable drive mechanism with strong structural rigidity that can ensure the precise and synchronous rotation of all louvers.

[0004] Secondly, regarding the structure and photothermal performance of louvers, common solutions either use standard opaque photovoltaic panels, which generate electricity but completely block light, affecting natural indoor lighting; or use simple parallel photovoltaic and light-transmitting strips, resulting in uneven light transmission, visual clutter, and an inability to effectively harmonize the comfort of incoming light. Current technology lacks a louver component that organically combines power generation and light transmission at the material level, creating a soft and uniform indoor lighting environment.

[0005] Furthermore, in terms of system integration and installation, the drive components, electrical circuits and support structures of existing systems are often arranged separately, resulting in a loose overall structure, an untidy appearance, complicated installation procedures, and inconvenience for later maintenance and replacement of individual louvers or drive units.

[0006] In summary, no existing technology has yet provided a solution that can simultaneously address the aforementioned problems: integrating a centralized mechanical drive mechanism with high rigidity and synchronization; employing a louver composed of a semi-transparent photovoltaic layer and a glass layer that balances power generation efficiency and visual comfort; and modularly and securely integrating the drive mechanism and the louver within a single mounting frame. Therefore, a novel glass photovoltaic louver system is needed to overcome these shortcomings. Utility Model Content

This system, through an integrated mechanical drive structure and a special photovoltaic-glass composite louver design, achieves the organic unity of power generation, shading, and lighting functions, and has advantages such as structural stability, precise control, and good visual effects.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] The glass photovoltaic louver unit includes several glass photovoltaic louvers arranged in parallel.

[0011] The drive mechanism is mounted on the mounting frame and includes a motor, a transmission plate connected to the output end of the motor, and multiple transmission connecting plates driven by the transmission plate to rotate synchronously.

[0012] Each of the transmission links is connected to one end of a corresponding glass photovoltaic louver, and is used to drive the glass photovoltaic louver to rotate around its own axis.

[0040] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments, but the scope of protection of the present invention is not limited to the following embodiments.

[0041] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0042] Please see Figures 1 to 4 The present invention provides a glass photovoltaic louver system, which mainly includes an installation frame 1, a drive mechanism 2, and one or more sets of glass photovoltaic louver units.

[0043] like Figure 1-2 As shown, the mounting frame 1 serves as the main support for the system and can be made of materials such as aluminum alloy profiles, and is fixed to the exterior wall or roof of the building. Multiple sets of glass photovoltaic louver units can be arranged longitudinally along the mounting frame 1.

[0044] The glass photovoltaic louver unit is composed of multiple parallel glass photovoltaic louvers 3. For example... Figure 4 As shown, the monolithic glass photovoltaic louver 3 is formed by laminating an outer photovoltaic panel 31 and an inner glass panel 32 together. The photovoltaic panel 31 is a semi-transparent crystalline silicon or thin-film photovoltaic module, preferably with a light transmittance greater than or equal to 50%. The glass panel 32 is also preferably made of semi-transparent or frosted glass. The photovoltaic panel 31 faces outwards to receive sunlight and generate electricity, while the glass panel 32 faces inwards to improve light perception. The combination of the two results in soft and uniform light penetrating into the room.

[0045] like Figure 3-4 As shown, each end of the glass photovoltaic louver 3 is mounted via a mounting bracket 4. The mounting bracket 4 has a longitudinal slot 41. The end of the glass photovoltaic louver 3 is directly inserted into the slot 41, and structural sealant (such as silicone structural adhesive) is poured into the slot 41 for bonding, fixing, and sealing. This connection method is robust and reliable, and has good water tightness and air tightness.

[0046] The drive mechanism 2 is integrated into the side or end of the mounting frame 1. It includes a motor 21 (such as a servo motor), a transmission plate 22 directly connected to the output shaft of the motor 21 or through a reducer, and a series of transmission connecting plates 23 fixed at equal intervals on the transmission plate 22. The transmission plate 22, the transmission connecting plates 23, and the transmission connecting rod 24 mentioned later are preferably made of steel to ensure transmission rigidity and durability.

[0047] Each transmission link 23 has its free end connected to the drive point at the end of a corresponding glass photovoltaic louver 3. More specifically, a central shaft assembly 43 (which may include bearings or bushings) is fixed in the middle of one side of the mounting frame 4, and this central shaft assembly 43 is coaxially fixed to the end of the glass photovoltaic louver 3. The transmission link 23 is hinged or snapped to this central shaft assembly 43. When the motor 21 starts and drives the transmission plate 22 to rotate, all the transmission links 23 swing synchronously, thereby driving all the glass photovoltaic louvers 3 to rotate synchronously around their respective axes, realizing continuous adjustment of the louver angle from fully closed to fully open.

[0048] To drive longer louvers or ensure balanced force distribution, another identical drive mechanism 2 can be symmetrically installed at the other end of the glass photovoltaic louver 3. The drive mechanisms 2 at both ends are rigidly connected by a transmission link 24 to ensure that the movements at both ends are completely synchronized.

[0049] The working principle of this invention is as follows: The control system sends a command to the motor 21 based on the sunlight intensity, time, or indoor illuminance requirements. The motor 21 drives the transmission plate 22 to rotate at a certain angle, and the transmission plate 22 transmits this rotational motion synchronously to each glass photovoltaic louver 3 through all the transmission connecting plates 23. The louvers stop after rotating to the predetermined angle. During this process, the photovoltaic panel 31 always faces the sun at the best or better angle, continuously generating electricity; at the same time, the angle change of the louvers dynamically controls the light and heat entering the room, achieving the purpose of energy saving and comfort.

[0050] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
