TECHNICAL FIELD
[0001] The present application relates to the technical field of building sunshade, in particular to a glare-proof and light-transmitting sunshade curtain and a manufacturing method thereof. BACKGROUND
[0002] In the design and construction process of a house, in order to meet the natural lighting and visual comfort of the house, glass windows are widely used. However, the use of glass windows also increases the air conditioning energy consumption of the room, and ultraviolet rays can easily penetrate, so it is necessary to install sunshade curtains on the glass windows.
[0003] In China, there are many high-rise buildings, and the outer surfaces are mostly glass curtain walls. Since the functions of the glass curtain walls are mostly office spaces, sunshade curtains are often used to block the sun in summer to reduce building energy consumption and prevent glare. The commonly used sunshade curtains can achieve this purpose after being pulled down, but for the indoor space, the city landscape brought by the glass curtain wall is lost. Moreover, because of the low attention of the user, there is also a situation that the sunshade curtain is not retracted after being pulled down, which makes the originally open and transparent space become closed, causing the user to feel disconnected from the outside environment. That is, the traditional sunshade curtain only focuses on sunshade and does not focus on meeting the natural lighting requirements. Moreover, even if the sunshade curtain focuses on lighting, the same structure of the sunshade curtain will still cause people to feel uncomfortable due to glare when used in different regions. In addition, if the glass is opened for ventilation, the sunshade curtain is easy to be blown by the wind, which may cause interference to the indoor and outdoor spaces.
[0004] CN207377458U discloses a solar energy sensing sunshade curtain, which comprises a mounting frame, the upper end of the mounting frame is provided with a sunshade curtain shell, the inside of the sunshade curtain shell is connected with a reel through bearings at both ends, a spring is arranged between the both ends of the reel and the sunshade curtain shell, the reel is wound with a sunshade curtain, the device is provided with electric energy through a solar charging panel, so that a large amount of electric energy can be saved, and the use is more convenient. The sunshade curtain can be retracted or opened through the rotation of the rotating shaft driven by the motor, so that the sunshade curtain can be opened or retracted, and the intensity of sunlight can be sensed through the light sensor to determine whether the sunshade curtain is retracted. The solar energy sensing sunshade curtain has the advantages of simple structure, easy operation, saving of a large amount of electric energy, automatic control of the sunshade curtain, and convenient use. The above patent realizes the automatic opening and closing of the sunshade curtain according to the intensity of sunlight through the cooperation of the light sensor, the motor and the rotating shaft. However, when the sunshade is opened, the originally open and transparent space becomes closed, causing the user to feel disconnected from the outside environment.
[0005] CN103291203B provides an anti-wind sunshade curtain, belonging to the mechanical technical field. It solves the problem of poor wind resistance of the existing curtain. The anti-wind sunshade curtain includes a roller blind cloth, a window cover, and a roller tube assembly. The roller tube assembly is assembled in the window cover, and the roller tube assembly is wound outside the roller blind cloth. The window cover is fixedly connected with a side rail at both ends downward. The side rail has a longitudinal opening on the side of the roller blind cloth. Two symmetrical clamping strips are arranged in the side rail in the longitudinal direction, and a gap is formed between the two clamping strips. The upper opening of the gap is connected with the window cover. The two side edges of the roller blind cloth respectively pass through the longitudinal opening of the same side rail and the gap between the two clamping strips, and then extend into the inner cavity of the side rail and are horizontally fixed on the flexible positioning member. The roller tube assembly has two symmetrical annular grooves, and when the roller blind cloth is wound on the roller tube, the two side edges of the roller blind cloth are wound in the corresponding annular grooves. The outer diameter of the positioning member is greater than the gap width between the two clamping strips. The above-mentioned patent has the advantages of stable and reliable structure, good guidance, and strong wind resistance. However, it still cannot balance sunshade and light transmission.
[0006] CN 102058310 A is a single-sided transparent sunshade curtain. The single-sided transparent sunshade curtain is uniformly pasted and covered on the transparent soft plastic curtain cloth with the sticky side of the single-sided transparent material commonly used in advertising and promotional materials. The single-sided transparent sunshade curtain has the following advantages: 1. It is not easy to stick dust, and even if it sticks dust, it is easy to clean. 2. The single-sided transparent sunshade curtain can be sprayed with various personalized patterns or advertisements on the outside, and the appearance is more beautiful. 3. The inside cannot be seen from the outside, but the outside can be clearly seen from the inside; it protects privacy and has good light transmission. 4. The single-sided transparent sunshade curtain is lighter than the cloth curtain. 5. Since the inside cannot be seen from the outside, the single-sided transparent sunshade curtain also has a certain sun protection function. Although the above-mentioned patent mentions light transmission and sunshade, it does not consider the discomfort caused by glare, and at the same time maintains the visual contact between the room and the outside, does not block the visual communication between the room and the outside, and presents a good visual landscape to the outside.
[0007] CN 211647928 U discloses an adjustable sunshade curtain device. This utility model utilizes three hybrid curtain types, allowing for adjustment to desired positions. When not in use, the curtain can be fully raised. The device is motor-operated, making it easy to operate and long-lasting. Other curtain types can be installed as needed. To use the device, the outer clipping end of the reel is placed into the slide slot, the fixed cover on the reel fixing platform is closed to secure the clip, and the tubular motor is started to drive the rotating wheel. When the sun is too glaring and the room needs complete light shielding, the blackout curtain can be adjusted to the window position. To achieve a certain brightness without excessive sunlight, the curtain can be adjusted to the light-transmitting curtain position. To achieve ventilation, the curtain can be adjusted to the ventilation curtain position. To achieve full ventilation, the fixed cover on the upper end of the reel fixing platform is opened to fully roll up the curtain. While the aforementioned patent allows for both light and ventilation, it requires separate operations. When light is required, the light-transmitting curtain is opened, and when ventilation is required, the ventilation curtain is opened. This fails to achieve both light and ventilation.
[0008] Therefore, based on the shortcomings of the current sunshade curtains, an anti-glare, light-transmitting sunshade curtain and a manufacturing method thereof are provided. Summary of the Invention
[0009] In response to the shortcomings of the above-mentioned existing technologies, an anti-glare, light-transmitting sunshade curtain and a manufacturing method thereof are provided, which can diffusely reflect sunlight into the room, so that the sunshade net has the functions of shading and light transmission, maintaining the visual connection between the indoor and outdoor of the room, and will not block the visual communication between the indoor and outdoor areas when shading, while reducing glare, improving comfort and reducing building energy consumption.
[0010] In order to solve the above technical problems, the technical solution adopted by the present invention is an anti-glare, light-transmitting sunshade curtain, including a pulling device arranged on the upper part of the curtain wall or window, and a retractable area composed of a fixed rod connected to the pulling device and a lifting rod arranged below the fixed rod and connected to the pulling device through a connecting rope.

A vertical traction rope is provided between the corresponding upper fixing parts and the lower fixing parts for connecting the two and passing through the blade connection point.
[0013] The anti-glare and light-transmitting sunshade curtain has a light and flexible material.
[0014] The method for manufacturing the anti-glare and light-transmitting sunshade curtain comprises the following steps.

[0021] (7) The dynamic parameters obtained in step (6) are used to manufacture a single blade made of a light and flexible material.
[0022] (8) The single blades are connected in a staggered manner to form a retractable sunshade net for diffusely reflecting sunlight into a room.
[0023] (9) The top and bottom of the sunshade net are fixed on a fixed rod and a lifting rod, respectively.

[0032] Figure 2 is a structural schematic view of the pulling device;
[0033] Figure 3 is a program flow chart of dynamic parameter optimization design of the present application. DETAILED DESCRIPTION
[0034] The present application will be described in detail below in combination with the drawings and specific embodiments.
[0035] As Figure 1 , 2As shown, an anti-glare, light-transmitting sunshade includes a pulling device 1 mounted on the upper portion of a curtain wall or window. Below the pulling device 1 is a retractable area comprising a fixed rod 2 connected to the pulling device 1 and a lifting rod 4, disposed below the fixed rod 2 and connected to the pulling device 1 via a connecting rope 3. Between the fixed rod 2 and the lifting rod 4 is a retractable sunshade net comprised of multiple identically wavy blades 5 connected in pairs, forming a staggered arrangement for diffusely reflecting sunlight into the room. The blades 5 are made of lightweight, flexible materials, including but not limited to lightweight offset paper, long-fiber non-woven fabric, and aluminum strips.
[0036] The manufacturing parameters of the length of a single blade 5 and its arc width and arc height are data that make the three target values of UDI, ACP and BEC comprehensively optimized.
[0037] Multiple upper fixings 6 are installed between the fixing rod 2 and the pulling device 1. A fixing plate 7 is installed on the windowsill, and multiple lower fixings 8 are installed on the fixing plate 7, corresponding to the upper fixings 6. A vertical traction rope 13 is installed between the corresponding upper and lower fixings 6 and passes through the connection point of the blade 5 to connect the two. The vertical traction rope 13 can be made of high-strength transparent rope, including but not limited to No. 60 1.3mm fishing line or 304 stainless steel wire. This maintains structural stability and ensures that the blade's bonding point moves vertically. The upper and lower fixings 6 and 8 can be equipped with appropriate snap locks according to the scenario.
[0038] This application can utilize a conventional sunshade pulling device, which includes a horizontal bar 9 mounted on the upper portion of a curtain wall or window, a reel 10 mounted within the horizontal bar 9, and a pulling cord 11 mounted on the reel 10. The connecting cord 3 is secured to the upper portion of the curtain wall or window via positioning members 12 on either side of the horizontal bar 9. When shading is required, the pulling cord 11 is used to pull down the sunshade net. Sunlight strikes the net and diffusely reflects into the room, providing shade and reducing glare while maintaining a visual connection between the interior and exterior of the room.
[0039] The above-mentioned method for manufacturing an anti-glare, light-transmitting sunshade curtain comprises the following steps:
[0040] (1): Install a pulling device on the upper part of the curtain wall or window;
[0041] (2): Setting static parameters and dynamic parameters; the static parameters include house type, room structure, HVAC system, and meteorological data;
[0042] (3): Model the building model according to the set static parameters;
[0043] (4): Lighting simulation settings;
[0044] (5): Calculate the target values of UDI, ACP and BEC in the room;
[0045] (6): Setting dynamic parameters, which are the length, width and height of a single blade, and optimizing the dynamic parameters to obtain the dynamic parameters that make the three target values of UDI, ACP and BEC comprehensively optimal;
[0046] (7): According to the dynamic parameters obtained in step (6), a single blade is made of a lightweight flexible material;
[0047] (8): The single blades are staggered and connected in pairs to form a retractable sunshade net for diffusely reflecting sunlight into the room;
[0048] (9): Fix the top and bottom of the sunshade net to the fixing rod and lifting rod respectively;
[0049] (10): A connecting rope connected to the lifting rod is provided on the pulling device.
[0050] In the step (3), a standard room may be used, or modeling may be performed based on an actual room.
[0051] In step (6), a multi-objective optimization plug-in is used to optimize the two target values using a genetic algorithm. The input dynamic parameters are continuously changed and judged to find the dynamic parameters that optimize the three target values of UDI, ACP, and BEC, thus completing the optimized design. The length, width, and height parameters of the single blade that best suits the local conditions are obtained. The multi-objective optimization plug-in is Ocputos.
[0052] In the step (9), a plurality of upper fixing members are arranged between the fixing rod and the pulling device, a fixing plate is arranged on the windowsill, a plurality of lower fixing members corresponding to the upper fixing members are arranged on the fixing plate, and a vertical traction rope for connecting the corresponding upper fixing members and the lower fixing members and passing through the blade connection point is arranged between the corresponding upper fixing members and the lower fixing members.
[0053] UDI (Useful Daylight Illuminance) is defined as the percentage of the year during which the daylight illuminance at the work surface is within a certain range (typically 100-2000 lux). It is generally believed that when the illuminance at a point falls below 100 lux, supplemental artificial lighting is necessary, while above 2000 lux, visual discomfort may occur. UDI is a commonly used daylight evaluation metric in lighting simulations.
[0054] The adaptive comfort calculation (ACP) model is based on hundreds of field studies investigating people's comfort in naturally ventilated buildings. This model can be used to calculate the impact of shading on the indoor thermal environment.
[0055] BEC (building energy consumption) refers to the annual energy consumption per unit area for heating, ventilation, air conditioning and lighting under set calculation conditions.
[0056] The sunshade designed in this application provides shade while allowing light and ventilation. In addition, the structure is stable and glare is reduced while providing shade, light and ventilation. The design method is convenient for customization in different regions, achieving sunshade and glare reduction, improving comfort and reducing building energy consumption.
[0057] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
