Description

Technical Field

[0001] This invention relates to the field of electric blinds technology, specifically to concealed photovoltaic electric blinds insulated glass. Background Technology

[0002] Built-in louvered insulated glass is widely used in various building scenarios such as residences, office buildings, hospitals, and schools due to its comprehensive performance in sun shading, light adjustment, heat insulation, and sound insulation.

[0003] Existing insulated glass products with built-in motorized blinds generally require external AC power, necessitating cumbersome on-site installation involving pre-installed wiring and trenching, and also posing a risk of leakage due to aging wiring. The few photovoltaic blind products available on the market mostly have the photovoltaic modules externally mounted on the window frame surface, with the photovoltaic components protruding outwards, resulting in poor overall window appearance consistency. Furthermore, photovoltaic modules exposed to the outdoor environment are subject to long-term wind, rain, dust accumulation, and sun aging, leading to surface dust buildup and oxidation damage, directly causing a rapid decline in photoelectric conversion efficiency and reduced equipment stability. Therefore, this invention proposes a concealed photovoltaic motorized blind insulated glass unit. Summary of the Invention

An outer glass panel is fixedly installed at the center of the outer frame along its height direction, and an inner glass panel is fixedly installed in the inner frame corresponding to the outer glass panel. A sealed hollow cavity is formed between the outer and inner glass panels. Photovoltaic panels are fixedly attached to both ends of the outer glass facing the inner glass. The photovoltaic panels are concealed within the hollow cavity, and their light-receiving surfaces can receive sunlight from the front end of the outer frame via the outer glass panel. An equipment cavity is fixedly mounted at the top of the inner frame, located on the inner wall of the outer frame, with its front end fixedly attached to the inner wall of the outer frame. Multiple sets of louvers are evenly arranged at the bottom of the equipment cavity along the height direction of the outer glass panel.

[0008] Preferably, transmission terminals are fixedly embedded on both sides of the equipment cavity. The transmission terminals are electrically connected to the photovoltaic panel and are used to transmit the electrical energy generated by the photovoltaic panel. A collaborative control mechanism is fixedly installed inside the equipment cavity at a position corresponding to the transmission terminals. The collaborative control mechanism is used to control the lifting and tilting of the louvers. An energy storage mechanism is fixedly installed in the middle of the equipment cavity to store the electrical energy output by the photovoltaic panel. The transmission terminals, the collaborative control mechanism, and the energy storage mechanism are electrically connected to each other to form a closed-loop power supply circuit inside the cavity.

[0009] Preferably, a limiting buckle is integrally formed at the position corresponding to the top of the photovoltaic panel inside the window frame. The photovoltaic panel is fixedly connected to the limiting buckle to limit and press the upper end of the photovoltaic panel, thereby realizing the positioning and installation of the photovoltaic panel inside the window frame.

[0010] Preferably, the inner frame of the window has an integrally formed bottom support plate at the position corresponding to the bottom end of the photovoltaic panel, and the bottom end of the photovoltaic panel is fixedly attached to the top of the bottom support plate, with the bottom support plate providing support for the bottom of the photovoltaic panel.

[0011] Preferably, a set of louvers located at the top of the bottom support plate has connecting buckles fixedly engaged on both sides. A hollow motor is connected to the side of the connecting buckle away from the louvers. The hollow motor outputs power through the connecting buckles to drive the louvers to adjust the blade angle.

[0012] Preferably, each side of the louver is provided with an electric slide rail, the rear end of which is fixedly connected to the inner wall of the window frame; a sliding seat is slidably connected to the side of the electric slide rail facing the louver, and a mounting plate is fixedly connected to the side of the sliding seat away from the electric slide rail; the rear end of the hollow motor is fixedly connected to the mounting plate, and the hollow motor moves synchronously with the sliding seat.

[0013] Preferably, side support plates are integrally formed on both sides of the equipment cavity, and the rear top position of the side support plates is fixedly connected to the inner wall of the window frame to fix the upper part of the equipment cavity.

[0014] Preferably, a fixing block is integrally formed at the top of the inner frame of the window corresponding to the position of the side support plate, and the bottom rear end of the side support plate is fixedly connected to the fixing block to fix the equipment cavity from the bottom.

[0015] Preferably, three sets of connecting ropes are evenly connected along the length of the multiple sets of louvers; the three sets of connecting ropes connect all the louvers into a whole assembly; a mounting frame is detachably connected to the bottom of the equipment cavity, and the top end of the connecting rope is fixedly inserted into the mounting frame to complete the end suspension and fixation of the multiple sets of louver assemblies.

[0016] Preferably, the front end of the equipment cavity is detachably fitted with an inspection cover plate, which can be opened to inspect and maintain the electrical components inside the cavity; the outer wall of the window frame is integrally formed with an outer frame, which is used for the assembly and positioning of the entire glass assembly with the building window opening.

[0017] In summary, the technical effects and advantages of this invention are as follows:

[0018] In this invention, the photovoltaic panel is integrally arranged inside the cavity of the insulated glass device. The photovoltaic panel is positioned against the inner sides of the outer glass, allowing it to receive external sunlight through the outer glass. The photovoltaic panel and the outer glass are at the same height, effectively expanding the light-collecting area and improving photovoltaic power generation capacity. The photovoltaic panel is internally and concealed, unlike traditional external photovoltaic structures. This avoids the defects of exposed photovoltaic components being affected by wind, rain, dust accumulation, and oxidation, which can lead to a decrease in photoelectric conversion efficiency. At the same time, there are no protruding components on the exterior of the window, ensuring the overall aesthetics of the building facade.

[0019] The louvered components are positioned behind the photovoltaic panel, with the two arranged in a staggered manner within the cavity. The normal raising, lowering, and rotating operation of the louvers will not interfere with the photovoltaic light collection, while fully preserving the original shading and light-dampening functions of the louvers, ensuring that the overall shading performance of the product is not affected.

[0020] The equipment cavity and inner window frame are detachably assembled to the rear of the outer window frame. The equipment cavity is located above the louvers and photovoltaic panels. The cavity integrates electrical components for energy storage and control. The electricity generated by the photovoltaic system can be stored and directly drive the louvers, achieving self-powered operation without external mains power. This eliminates the need for on-site wiring and reduces construction costs, while also eliminating the safety hazards of aging and leakage from external wiring. The inner window frame is fitted with inner glass, which, together with the outer glass, forms a sealed hollow cavity. This encloses the photovoltaic panels and louvers, isolating them from external dust, rain, and moisture, reducing component corrosion and dust accumulation, and lowering the frequency and cost of future maintenance.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] refer to Figures 1-7 The concealed photovoltaic motorized louvered insulated glass shown is illustrated in the following specific embodiment:

[0031] Example 1

[0032] This embodiment discloses a concealed photovoltaic motorized louvered insulated glass unit. The outer frame 1 serves as the external base of the entire glass assembly, and the inner frame 4 is detachably assembled at the rear end of the outer frame 1. An outer glass 101 is fixedly installed at the center of the outer frame 1 along the height direction, and an inner glass 401 is fixedly installed in the inner frame 4 at the position corresponding to the outer glass 101. The outer glass 101 and the inner glass 401 cooperate with each other to form a sealed hollow cavity.

[0033] The equipment cavity 5 is fixedly assembled on the top of the inner frame 4 of the window and is also fitted against the inner side wall of the outer frame 1 of the window. Two integrally formed side support plates 501 are mounted on both sides of the equipment cavity 5, with the top rear side of the side support plates 501 connected to the inner side wall of the outer frame 1. A fixing block 402 is integrally formed on the top of the inner frame 4 corresponding to the position of the side support plates 501, with the bottom rear side of the side support plates 501 fixedly connected to the fixing block 402. The bidirectional connection between the side support plates 501 and both the outer frame 1 and the inner frame 4 completes the dual positioning and fixing of the equipment cavity 5, ensuring its stable installation. A detachable maintenance cover plate 502 is installed at the front end of the equipment cavity 5. The equipment cavity 5 houses a transmission terminal 7, a collaborative control mechanism 8, and a power storage mechanism 9. A detachable mounting bracket 202 is connected to the bottom of the equipment cavity 5. The top end of the connecting rope 201 of the louver 2 is inserted and fixed to the mounting bracket 202, allowing the louver 2 to be suspended as a whole within the hollow cavity below the equipment cavity 5.

[0034] In actual assembly and use, the outer frame 1 and outer glass 101 are pre-assembled first. Then, the equipment cavity 5 is connected to the inner wall of the outer frame 1 and the fixing block 402 of the inner frame 4 via the side support plate 501. Subsequently, the inner frame 4 is assembled to the rear end of the outer frame 1 to form a closed hollow cavity. In case of electrical faults, the inspection cover plate 502 at the front end of the equipment cavity 5 can be removed to inspect and maintain the internal components. The outer wall of the outer frame 1 is integrally formed with an outer frame 102, which allows the entire glass assembly to be directly assembled to the building window opening.

[0035] Example 2

[0036] In this embodiment, there are two sets of photovoltaic panels 3, which are fixedly attached to both ends of the outer glass 101 facing the inner glass 401. All photovoltaic panels 3 are housed in the hollow cavity inside the window frame 1. Inside the window frame 1, a limiting buckle 103 is integrally formed at the top position of the photovoltaic panel 3. The upper end of the photovoltaic panel 3 is fixedly connected to the limiting buckle 103, and the limiting buckle 103 completes the upper end limiting and pressing. The inner window frame 4 is integrally formed with a bottom support plate 403. The bottom end of the photovoltaic panel 3 is attached to the upper surface of the bottom support plate 403. The limiting buckle 103 and the bottom support plate 403 achieve bidirectional constraint and fixation of the photovoltaic panel 3.

[0037] The photovoltaic panel 3 has its light-receiving surface flush against the inner side of the outer glass 101, allowing sunlight to directly reach the photovoltaic panel 3 through the outer glass 101. The overall height of the photovoltaic panel 3 is adapted to the outer glass 101, making full use of the vertical space of the window to collect light energy. The photovoltaic panel 3 is electrically connected to the energy storage mechanism 9 and the collaborative control mechanism 8 inside the equipment cavity 5 via the transmission terminal 7. The photovoltaic panel 3 receives sunlight and generates electrical energy, which is then transmitted to the energy storage mechanism 9 via the transmission terminal 7 for storage, providing energy for the operation of the louver system.

[0038] During use, the photovoltaic panel 3 is completely inside the sealed hollow cavity and is not exposed to the outdoor environment, avoiding the problem of conversion efficiency degradation caused by wind, rain, dust and oxidation; the louvers 2 are arranged on the back side of the photovoltaic panel 3, and the lifting and flipping of the louvers 2 will not block the light-receiving area of ​​the photovoltaic panel 3, thus taking into account both photovoltaic power generation and louver shading functions.

[0039] Example 3

[0040] In this embodiment, multiple sets of louver blades 2 are evenly arranged along the height direction of the outer glass 101. Three sets of connecting ropes 201 are installed through the louver blades 2 along their own length direction. The connecting ropes 201 connect all the louver blades 2 together to form a louver assembly. The top of the connecting ropes 201 is inserted into and fixed to the mounting bracket 202 at the bottom of the equipment cavity 5. Electric sliding rails 6 are provided on both sides of the louver blades 2. The rear end of the electric sliding rails 6 is fixedly connected to the inner wall of the window frame 1. The electric sliding rails 6 are slidably mounted on the sliding seat 601 facing the louver blades 2. The mounting plate 602 is fixedly installed on the outer side of the sliding seat 601.

[0041] A set of louvers 2 located above the base plate 403 is connected to connecting buckles 1001 on both sides. The rear end of the hollow motor 10 is fixedly mounted on the mounting plate 602. The output end of the hollow motor 10 and the connecting buckles 1001 form a transmission cooperation, which can adjust the shading angle of the louvers 2. The hollow motor 10 follows the sliding seat 601 and slides vertically synchronously along the electric slide rail 6. The power storage mechanism 9 outputs electrical energy to the coordination control mechanism 8. The coordination control mechanism 8 controls the sliding seat 601 on the electric slide rail 6 to operate. Then, through the connecting buckles 1001 on one side of the hollow motor 10, it drives the lowest set of louvers 2. Under the linkage of the connecting rope 201, it drives all the louvers 2 to achieve an overall lifting and lowering action along the electric slide rail 6.

[0042] In use, the collaborative control mechanism 8 issues an action command, and the sliding seat 601 slides vertically on the electric slide rail 6. The electric slide rail 6 guides and limits the louver 2 throughout its lifting and lowering process, preventing the louver from shifting or jamming. The louver 2 is driven by the connecting buckle 1001 on one side of the hollow motor 10 to complete the shading angle adjustment. The entire drive structure is arranged inside the hollow cavity, without occupying the external space of the window. It relies on internal energy storage for power supply and does not require external mains power wiring. It can complete the lifting and lowering adjustment of the louver and realize shading and light adjustment.

[0043] Working principle of this invention:

[0044] Sunlight shines through the outer glass 101 onto the photovoltaic panels 3 arranged on both sides inside the hollow cavity. The photovoltaic panels 3 receive the sunlight and convert the light energy into electrical energy. The generated electrical energy is transmitted through the transmission terminal 7 to the energy storage mechanism 9 inside the equipment cavity 5 for storage. The coordination control mechanism 8 is electrically connected to the energy storage mechanism 9 to coordinate and manage the distribution of electrical energy. The entire power supply circuit is set in the sealed hollow cavity, eliminating the need for external mains power wiring.

[0045] The photovoltaic panel 3 is fixed in place by the limiting buckle 103 and the bottom support plate 403, and is housed inside the hollow cavity, protected from outdoor rain and dust, thus ensuring photoelectric conversion efficiency. The outer window frame 1 and the inner window frame 4 are assembled to form a sealed hollow cavity. The equipment cavity 5 is doubly positioned by the side support plate 501 and the fixing blocks 402 on the outer window frame 1 and the inner window frame 4, respectively. The mounting bracket 202 at the bottom of the equipment cavity 5 suspends the entire louver 2 through the connecting rope 201.

[0046] When the louver status needs to be adjusted, the coordinated control mechanism 8 retrieves the electrical energy stored in the energy storage mechanism 9 and outputs control signals to the hollow motor 10 and the sliding seat 601. The electric slide rail 6 is fixed to the inner wall of the window frame 1, and the sliding seat 601 can slide vertically along the electric slide rail 6. The hollow motor 10 moves synchronously with the sliding seat 601. The hollow motor 10 is connected to the louver blades 2 through the connecting buckle 1001. On the one hand, it drives the louver blades 2 to adjust the shading and flip angle, and on the other hand, it drives the bottom group of louver blades 2 to move vertically. Under the linkage traction of the connecting rope 201, it drives all the louver blades 2 to complete the overall lifting and lowering action.

[0047] The electric slide rail 6 guides and limits the lifting and lowering movement of the louvers 2, preventing them from shifting or jamming during operation. A maintenance cover 502 is installed at the front end of the equipment cavity 5, allowing for access to the internal electrical components in case of malfunction. The louvers 2 are positioned behind the photovoltaic panel 3, ensuring that their lifting, lowering, and angle adjustment do not obstruct the sunlight reaching the photovoltaic panel 3. The device simultaneously achieves multiple functions: photovoltaic power generation, thermal insulation and soundproofing, and shading and light adjustment.

[0048] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
