Description

Technical Field

[0001] This utility model relates to blinds, and more particularly to a solar-powered blind. Background Technology

[0002] An existing type of Venetian blind includes a window frame, a glass panel, and a blind assembly. The glass panel is located within the window frame, and the blind assembly is installed on the window frame. The blind assembly includes multiple parallel slats and a slat drive mechanism for driving the slats to rise, fall, rotate, and open / close. To improve the utilization rate of sunlight, another existing type of Venetian blind replaces the glass panel with photovoltaic glass. The photovoltaic glass has a photovoltaic layer that generates electricity when exposed to sunlight. This photovoltaic layer has a certain light transmittance, generating electricity through sunlight during the day, while allowing some light to pass through for indoor lighting. When the blind assembly is not blocking light, some light passes through the photovoltaic layer to illuminate the room; when the blind assembly blocks light, it blocks the light from entering the room. However, the current solar-powered Venetian blinds still have insufficient efficiency in generating electricity from sunlight. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a solar-powered louver that can further improve the efficiency of generating electricity using sunlight.

[0004] According to an embodiment of the present invention, a solar-powered venetian blind includes a window frame, a light-transmitting component, and a venetian blind assembly. The window frame has a frame opening; the light-transmitting component is disposed on the window frame and includes a first light-transmitting plate located within the frame opening, the first light-transmitting plate having a light-transmitting photovoltaic layer; the venetian blind assembly is disposed on the window frame and located on the indoor side of the first light-transmitting plate, the venetian blind assembly including multiple parallel blades and a blade driving mechanism, the blade driving mechanism driving the blades to move, and the outer surface of the blades having a reflective layer.

[0005] According to the embodiments of the present invention, the solar-powered venetian blinds have at least the following beneficial effects: the window frame is installed at the window, and during the day, sunlight can irradiate the photovoltaic layer on the first light-transmitting plate to generate electricity. The photovoltaic layer has a certain light transmittance, and some light can pass through the first light-transmitting plate. When the venetian blind assembly does not block the light, it can provide indoor lighting. Since the venetian blind assembly is located on the indoor side of the light-transmitting assembly, and the outer surface of the blade has a reflective layer, when the blade driving mechanism drives the blade to move to block the light, the light passing through the first light-transmitting plate will be reflected by the blade and irradiate the photovoltaic layer on the first light-transmitting plate a second time, thereby improving the power generation efficiency of utilizing sunlight.

[0009] According to some embodiments of the present invention, the photoelectric generation layer is provided on both sides of the first light-transmitting plate.

[0010] According to some embodiments of this utility model, the photovoltaic layer is a cadmium telluride layer or a perovskite layer.

[0011] According to some embodiments of the present invention, the light-transmitting component includes two second light-transmitting plates, which are arranged in parallel and spaced apart.

[0013] According to some embodiments of the present invention, the light-transmitting component further includes a third light-transmitting plate, which is located on the outdoor side of the first light-transmitting plate. The third light-transmitting plate is parallel to the first light-transmitting plate, and the second light-transmitting plate is parallel to the first light-transmitting plate. One side wall of the first light-transmitting plate is connected to the third light-transmitting plate by a light-transmitting adhesive layer, and the other side wall of the first light-transmitting plate is connected to one of the second light-transmitting plates by the light-transmitting adhesive layer.

[0029] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0030] Reference Figures 1 to 2This utility model describes a solar-powered venetian blind, comprising a window frame 100, a light-transmitting component 200, and a venetian blind assembly 300. The window frame 100 has a frame hole; the light-transmitting component 200 is disposed on the window frame 100 and includes a first light-transmitting plate 210 located within the frame hole, and the first light-transmitting plate 210 has a light-transmitting photovoltaic layer 211; the venetian blind assembly 300 is disposed on the window frame 100 and located on the indoor side of the first light-transmitting plate 210, and the venetian blind assembly 300 includes multiple parallel blades 310 and a blade driving mechanism 320, the blade driving mechanism 320 driving the blades 310 to move, and the outer surface of the blades 310 having a reflective layer.

[0031] The window frame 100 is installed at the window. During the day, sunlight can shine on the photovoltaic layer 211 on the first light-transmitting plate 210 to generate electricity. The photovoltaic layer 211 has a certain light transmittance, and some light can pass through the first light-transmitting plate 210. When the Venetian blind assembly 300 does not block the light, it can provide indoor lighting. Since the Venetian blind assembly 300 is located on the indoor side of the light-transmitting assembly 200, and the outer surface of the blade body 310 has a reflective layer, when the blade drive mechanism 320 drives the blade body 310 to move to block the light, the light passing through the first light-transmitting plate 210 will be reflected by the blade body 310 and shine on the photovoltaic layer 211 of the first light-transmitting plate 210 a second time, thereby improving the power generation efficiency of utilizing sunlight.

[0032] Specifically, the photovoltaic layer 211 can also provide some shade from sunlight, reducing direct sunlight entering the room.

[0033] Specifically, the blade body 310 is mainly made of aluminum sheet, and the reflective layer is a titanium dioxide layer. The titanium dioxide layer is deposited on the outer surface of the blade body 310 by physical vapor deposition. It is conceivable that in other embodiments, the light-emitting layer may also be made of reflective film, electroplated reflective metal layer, or other methods.

[0034] In this embodiment, the photovoltaic layer 211 has perforated gaps. By creating these gaps, the photovoltaic layer 211 achieves a certain light transmittance, allowing light to pass through. This method of achieving light transmittance is relatively simple. Specifically, the photovoltaic layer 211 is a cadmium telluride layer or a perovskite layer, and the perforated gaps can be created during production using chemical etching or laser etching.

[0035] It is conceivable that in other embodiments, the light-generating layer 211 can also be made transparent in other ways. For example, the light-generating layer 211 may be densely covered with light-transmitting holes to make the light-generating layer 211 transparent, or the light-generating layer 211 may be arranged in an array of multiple sub-sheets with gaps between adjacent sub-sheets, and the gaps may make the light-generating layer 211 transparent.

[0036] In this embodiment, the first light-transmitting plate 210 is provided with two or more photovoltaic layers 211, all of which are parallel to each other. Providing two or more photovoltaic layers 211 further improves the utilization efficiency of sunlight for power generation, thus enhancing the power generation effect.

[0037] In this embodiment, the photovoltaic layer 211 and the first light-transmitting plate 210 are parallel to each other, and the arrangement of the photovoltaic layer 211 on the first light-transmitting plate 210 is relatively simple and easy to implement.

[0038] In this embodiment, a photovoltaic layer 211 is provided on both sides of the first light-transmitting plate 210, which has a high utilization rate of sunlight and saves manufacturing costs; and can also improve the power generation utilization rate of indoor lights.

[0039] In some embodiments, a plurality of photoelectric generating layers 211 may be provided on the first light-transmitting plate 210. For example, the first light-transmitting plate 210 may also include two or more substrate layers, which are arranged along the thickness direction, and photoelectric generating layers 211 are arranged between adjacent substrate layers. The substrate layers and photoelectric generating layers 211 are stacked and connected. Alternatively, a plurality of first light-transmitting plates 210 may be provided along their thickness direction, and all first light-transmitting plates 210 may be stacked and connected.

[0040] In this embodiment, the photovoltaic layer 211 is a cadmium telluride layer or a perovskite layer. The photovoltaic layer 211, made of cadmium telluride or perovskite material, has high light absorption capacity and can maintain good power generation capacity in low-light environments. It is understood that when the first light-transmitting plate 210 has multiple photovoltaic layers 211, some may be cadmium telluride layers and others may be perovskite layers.

[0041] Specifically, since the photovoltaic layer 211 is a cadmium telluride layer or a perovskite layer, it still has a certain power generation capacity under low light conditions. Therefore, when the blinds do not block the window, indoor lights can also shine on the photovoltaic layer 211 to generate electricity, thereby improving the utilization rate of ambient light sources.

[0042] It is conceivable that in other embodiments, the photovoltaic layer 211 may also be a monocrystalline silicon or polycrystalline silicon photovoltaic structure, which is not limited here.

[0043] In this embodiment, the light-transmitting component 200 includes two second light-transmitting plates 220, which are arranged in parallel and spaced apart. The second light-transmitting plates 220 are located in the frame opening, and their outer peripheries are connected to the window frame 100. The window frame 100 and the two second light-transmitting plates 220 enclose a hollow cavity 400, within which the Venetian blind assembly 300 is located. The hollow cavity 400, formed by the two second light-transmitting plates 220, provides good noise reduction and heat insulation, and the light-transmitting component 200 offers good protection. Simultaneously, the two second light-transmitting plates 220, in conjunction with the window frame 100, isolate and protect the Venetian blind assembly 300, preventing external rainwater and dust from easily contacting it and thus reducing the risk of soiling.

[0044] In this embodiment, one of the second light-transmitting panels 220 is tempered glass, and the other is low-emissivity glass. Using tempered glass for one of the second light-transmitting panels improves the structural strength of the entire light-transmitting component 200, making it less susceptible to damage from external forces. Using low-emissivity glass for the other second light-transmitting panel provides the light-transmitting component 200 with superior heat insulation and relatively high light transmittance, resulting in energy savings and environmental friendliness.

[0045] Specifically, low-emissivity glass can be made by forming a thin film with low-emissivity function on the glass surface using chemical vapor deposition, or by depositing a multi-layer composite film on the glass surface using vacuum magnetron sputtering after the glass has cooled.

[0046] In this embodiment, the light-transmitting component 200 further includes a third light-transmitting plate 230, which is located on the outdoor side of the first light-transmitting plate 210. The third light-transmitting plate 230 is parallel to the first light-transmitting plate 210, and the second light-transmitting plate 220 is parallel to the first light-transmitting plate 210. One side wall of the first light-transmitting plate 210 is connected to the third light-transmitting plate 230 by a light-transmitting adhesive layer 500, and the other side wall of the first light-transmitting plate 210 is connected to one of the second light-transmitting plates 220 by a light-transmitting adhesive layer 500. The third light-transmitting plate 230 is made of tempered glass. The third light-transmitting panel 230 is connected to the outdoor side of the first light-transmitting panel 210 via a light-transmitting adhesive layer 500, and one of the second light-transmitting panels 220 is connected to the indoor side of the first light-transmitting panel 210 via a light-transmitting adhesive layer 500, so that the first light-transmitting panel 210, the third light-transmitting panel 230 and the second light-transmitting panel 220 are directly combined. The tempered glass makes the combined structure relatively firm and improves the impact resistance of the light-transmitting component 200.

[0047] Specifically, the light-transmitting adhesive layer 500 is made of PVB, and the first light-transmitting plate 210, the second light-transmitting plate 220, and the third light-transmitting plate 230 are all glass. PVB has good adhesion to glass, and the first light-transmitting plate 210, the second light-transmitting plate 220, and the third light-transmitting plate 230 are bonded together by heating and pressurizing PVB. It is understood that in some other embodiments, the light-transmitting adhesive layer 500 may also be made of other materials, such as silicone adhesive or acrylic adhesive, etc., which is not limited here.

[0048] It is conceivable that in other embodiments, the first light-transmitting plate 210 may also be made of other materials, such as a resin plate with high light transmittance, etc., which is not limited here; the second light-transmitting plate 220 may also be made of other materials, such as a resin plate with high light transmittance, etc., which is not limited here; the third light-transmitting plate 230 may also be made of other materials, such as a resin plate with high light transmittance, etc., which is not limited here.

[0049] In this embodiment, a storage battery 600 is also included. The storage battery 600 is disposed on the window frame 100 and electrically connected to the photovoltaic layer 211. The storage battery 600 allows for the storage of electrical energy generated by the photovoltaic layer 211 for later use, making it relatively convenient. Specifically, the storage battery 600 can be a lithium battery, and it can be connected to the second light-transmitting plate 220, indirectly disposed on the window frame 100.

[0050] Specifically, the overall light transmittance of the first light-transmitting plate 210, together with the photovoltaic layer 211, can be selected from 10% to 90%.

[0051] Specifically, the blade drive mechanism 320 also includes a motor and a transmission structure. The motor drives the blade body 310 to move through the transmission structure. The motor is electrically connected to the battery 600. The electrical energy generated by the photovoltaic layer 211 is stored in the battery 600 and can be used to power the motor, providing a physical basis for the automatic adjustment of the blade body 310. The blade drive mechanism 320 in the venetian blind assembly 300 can adopt a commercially available structure to drive the blade body 310 to move.

[0052] Specifically, the blade drive mechanism 320 can be controlled remotely to adjust the operating status of the venetian blind assembly 300.

[0053] Specifically, the blades 310 of the Venetian blind assembly 300 can be moved or rotated to block or avoid light.
