Description

Technical Field

[0001] The utility model relates to the technical field of blinds, in particular to a thin-film photovoltaic blind. Background Art

[0002] As people's requirements for indoor environmental comfort increase, sunshade blinds that can realize lighting adjustment functions have been increasingly used in buildings. However, the opening, closing, and angle adjustment of the blinds all require external power drive motors, which increases building energy consumption. The current sunshade blinds only achieve simple shielding of sunlight, and the blocked solar energy is reflected in vain and is not effectively utilized. Photovoltaic power generation using solar energy usually requires larger photovoltaic glass components, junction boxes, and supporting structure systems. The relatively complex structure and large space occupation limit its application. Therefore, it is particularly important to study the technology of combining solar energy utilization with building shading.

[0003] With the improvement of people's environmental awareness and the trend of carbon reduction, photovoltaic blinds that can realize lighting and power generation adjustment functions have been increasingly used in buildings. However, most of the existing photovoltaic blinds set the power generation components on the blinds. Although the photovoltaic blades have been miniaturized, it has also brought about the miniaturization of circuits and electronic components. However, this method frequently retracts and folds the photovoltaic blinds during the process of opening, closing, and adjusting the angle of the blinds, which is prone to problems such as loose components and circuit breaks during use. At the same time, since photovoltaic blades need to chase light to generate electricity, they cannot take into account both lighting and power generation, which has shortcomings. Utility Model Content

[0004] One of the purposes of the utility model is to avoid the deficiencies in the prior art and provide a thin-film photovoltaic blind that can provide a certain light transmittance, and the power generation components do not move, thereby reducing the failure rate of the photovoltaic components and taking into account both lighting and power generation.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] Provided is a thin-film photovoltaic blind, comprising:

[0007] A window, the window comprising a window frame, an inner layer of glass and an outer layer of glass arranged on the window frame, and an electric blind arranged on the upper part of the window frame;

[0008] Thin-film photovoltaic, arranged on the inner side of the outer glass;

[0009] The energy storage device is arranged at the lower part of the window frame and is electrically connected to the thin-film photovoltaic and the electric venetian blinds.

[0010] Specifically, the thin-film photovoltaic blinds also include a lifting control mechanism, and the lifting control mechanism is used to control the lifting of the electric blinds.

[0011] Specifically, the lifting control mechanism includes a main control module, a transmitting device and a communication module. The transmitting device is arranged on the window body and is used to store the position information data of the lifting and lowering of the electric venetian blind; the communication module is used to extract and send the position information data of the transmitting device; the main control module is connected to the electric venetian blind and the communication module, and is used to receive the position information data and control the lifting and lowering of the electric venetian blind.

[0012] Specifically, the transmitting device includes multiple NFC tags, which store information codes of corresponding predetermined positions; the communication module is an NFC reader; the main control module is a mobile terminal, which stores a lifting control database according to the multiple predetermined position information codes.

[0013] Specifically, the transmitting device also includes a box body, and the multiple NFC tags are arranged in the box body.

When strong light is needed indoors, the blinds can be flipped to an angle roughly parallel to the direction of sunlight in the same way as existing blinds. When light is not needed indoors, the blinds can be flipped to an angle parallel to the plane of the window frame, so that the blinds completely block the penetration of light, and the thin-film photovoltaic does not participate in the raising and lowering of the blinds. The thin-film photovoltaic can generate electrical energy through photoelectric conversion in both shading and lighting conditions, and can avoid frequent folding and moving of the photovoltaic during the raising and lowering process, which may lead to undesirable phenomena such as loose components and broken lines.

[0029] The preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0030] As people's requirements for indoor environmental comfort increase, sunshade blinds that can realize lighting adjustment functions have been increasingly used in buildings. However, the opening, closing, and angle adjustment of the blinds all require external power drive motors, which increases building energy consumption. Currently used sunshade blinds only achieve simple shielding of sunlight, and the blocked solar energy is reflected in vain and is not effectively utilized. Photovoltaic power generation using solar energy usually requires larger photovoltaic glass components, junction boxes, and supporting structure systems. The relatively complex structure and large space occupation limit its application. Therefore, it is particularly important to study the technology of combining solar energy utilization with building shading.

[0031] With the improvement of people's environmental awareness and the general trend of carbon reduction, photovoltaic blinds that can realize lighting and power generation adjustment functions have been increasingly used in buildings. However, most of the existing photovoltaic blinds have power generation components set on the blinds. The application of photovoltaic blades to the blinds has achieved miniaturization, but it has also brought about the miniaturization of circuits and electronic components. This requires frequent retraction and folding of the photovoltaic blinds during opening, closing, and angle adjustment of the blinds, which may easily lead to problems such as loose components and broken circuits during use. At the same time, since photovoltaic blades need to chase light to generate electricity, they cannot take into account both lighting and power generation, which has some shortcomings.

[0032] To address this problem, the thin-film photovoltaic blinds disclosed in this embodiment, such as Figures 1 to 4 As shown, the window body includes a window frame 1, an inner glass layer 4 and an outer glass layer 3 arranged on the window frame, and an electric venetian blind 2 arranged on the upper part of the window frame; a thin film photovoltaic 5 arranged on the inner side of the outer glass 3; an energy storage device 7 arranged at the lower part of the window frame 1 and electrically connected to the thin film photovoltaic 5 and the electric venetian blind 2.

[0033] Specifically, the folding method of the venetian blinds of the photovoltaic blinds is the same as the folding method of the existing blinds. The difference is that the thin-film photovoltaic 5 has a certain light transmittance. It is installed on the inner side of the outer layer of glass 3 of the window body and can be fixed. The thin-film photovoltaic 5 does not fold as the electric venetian blinds 2 are retracted and extended, which has the effect of protecting the line. During the lighting process, the position of the venetian blinds can be adjusted according to the actual situation, taking into account both lighting and power generation.

[0034] In another specific embodiment of the present invention, the above-mentioned thin-film photovoltaic blinds further include a lifting control mechanism, and the lifting control mechanism is used to control the lifting of the electric blinds.

[0035] By providing a lifting control mechanism on the thin-film photovoltaic blinds, the lifting control mechanism can quickly respond to the lifting of the blinds, thereby improving user experience and reducing operation time.

[0036] In another specific embodiment of the present invention, the lifting control mechanism of the above-mentioned thin-film photovoltaic blinds includes a main control module, a transmitting device 6 and a communication module. The transmitting device 6 is arranged on the window body 1, and is used to store the position information data of the lifting and lowering of the electric blinds 2; the communication module is used to extract and send the position information data of the transmitting device 6; the main control module is connected to the electric blinds and the communication module, and is used to receive the position information data and control the lifting and lowering of the electric blinds 2.

[0037] The lifting position information data of the electric venetian blind 2 is stored on the transmitting device 6. The user can select different position information data according to the actual situation, use the communication module to extract the current position information, and then use the communication module to send a signal to the main control module. The main control module controls the lifting of the electric venetian blind to the required height according to the received position information, thereby realizing the lifting of the venetian blind.

[0038] In another specific embodiment of the present invention, the transmitting device 6 of the above-mentioned thin-film photovoltaic blinds includes multiple NFC tags 602, and the NFC tags 602 store information codes of corresponding predetermined positions; the communication module is an NFC reader / writer; the main control module is a mobile terminal, and the mobile terminal stores a lifting and lowering control database encoded according to multiple predetermined position information.

[0039] NFC is a near field communication technology with low energy consumption. It can respond to the communication signal sent by the receiving module within a sensing distance of 10 cm. The position relationship corresponding to the lifting and lowering of the electric blinds 2 is pre-set on each NFC tag 602. The NFC tag 602 can be sensed by an NFC reader (not shown) and then sent to a mobile terminal (not shown). The mobile terminal controls the lifting and lowering of the electric blinds 2 according to the pre-set position code and the corresponding position information code, without pressing the remote control key for a long time. In addition, when there are a large number of blinds, the lifting and lowering control of each blind can be quickly completed through a reader.

[0040] In another specific embodiment of the present invention, the transmitting device 6 of the thin-film photovoltaic blinds further includes a box body 601 , and the plurality of NFC tags 602 are disposed in the box body 601 .

[0041] In another specific embodiment of the present invention, the box body 601 of the thin-film photovoltaic blind has a bendable structure, and the plurality of NFC tags 602 are arranged equidistantly inside the box body 601 .

[0042] Specifically, see Figure 3 The box body 601 is configured as a bendable structure, and different amounts of NFC tags 602 can be selected according to the size of the blinds and the installation height to adapt to different scenarios. When two NFC tags 602 are used, the opening and closing functions of the blinds can be realized. The more NFC tags 602 there are, the smaller the percentage of the lifting position corresponding to each NFC tag 602 is, and the lifting control is more precise. The equidistant arrangement method can effectively reduce the communication interference between the NFC tags 602, and has a visualized operation space.

[0043] In another specific embodiment of the present invention, the box body 601 of the thin-film photovoltaic blind can be bent to form a pattern; the pattern includes one of a linear shape, a circular shape and an elliptical shape.

[0044] The box body 601 can be bent into various patterns, and can be made into a straight line, a circle, or an ellipse pattern according to actual conditions to improve the user experience, which is not the only limitation here.

[0045] In another specific embodiment of the present invention, the emitting device 6 of the thin-film photovoltaic blinds is detachably connected to the window body 1 .

[0046] Specifically, see Figure 2 and Figure 3 The user can install the box body 601 at any position of the window or place it away from the window according to the installation site of the blinds, the user's own height or ease of use.

[0047] In another specific embodiment of the present invention, the energy storage device 7 of the above-mentioned thin-film photovoltaic blinds also includes a lithium iron phosphate battery 701, and the lithium iron phosphate battery 701 is provided with a power detection and display device 702; the power detection and display device 702 is provided with a USB charging socket 703, and the display screen in the power detection and display device 702 faces the room.

[0048] Specifically, see Figure 4 The thin-film photovoltaic 5 will be affected by climate and time during use, and its power generation efficiency will be different. When the blinds in the blinds are raised and lowered frequently, the power can be monitored in real time according to the power detection display device 702 to avoid power shortage. The lithium iron phosphate battery 701 can be charged externally without affecting the actual use of the blinds.

[0049] In another specific embodiment of the utility model, the thin film photovoltaic 5 of the thin film photovoltaic blinds is a weak light power generation solar film. The weak light power generation solar film is light, thin, and has a light transmittance of 20% to 50%, which can effectively meet the needs of lighting and power generation.

[0050] The above-mentioned thin-film photovoltaic blinds, the weak-light power generation solar film is installed on the inner side of the outer glass 3, which can reduce dust falling. The lifting and lowering blinds do not affect the use of thin-film photovoltaics, taking into account both lighting and power generation needs. The different installation positions of the lifting control device can be selected according to the installation position of the window and the height of the human body. Different shapes of NFC tag boxes can also be selected according to the size of the window, which can greatly improve the speed of lifting control.

[0051] In this specification, each embodiment is described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referred to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part.
