At the same time, the existing curtain wall ventilation design is not scientific enough and the ventilation volume cannot be flexibly adjusted according to the season and actual needs. The fixed structure of the existing curtain wall is not stable enough and the installation and disassembly are not convenient enough.

[0004] The technical solution of the present invention to solve the above technical problems is as follows: a building thermal insulation curtain wall structure, including a curtain frame and two groups of hanging beams, a retracting system is installed in the curtain frame, a curtain belt is rolled up on the retracting system, an open hole is opened on the end face of the curtain frame to match the curtain belt, and a sunshade area, a light-transmitting area, a protection area, a ventilation area and an air bag area are sequentially arranged on the curtain belt, a louver frame is slidably installed on the inner wall of the curtain frame, a group of limit springs limited by the curtain frame are installed on the louver frame, a group of photovoltaic louver units that are linked to each other by belts are rotatably installed on the inner wall of the louver frame, a motor is installed on the louver frame, and the output shaft end of the motor is connected to one of the photovoltaic louvers. The leaf unit is fixedly connected, and an insulation ring bag is installed on the inner wall of the curtain frame at a position corresponding to the rear side of the louver frame. An air pump is installed on the side of the curtain frame, and air is supplied to the insulation ring bag and the inflatable bag area by the air pump. A ventilation component and a glass transparent plate are respectively provided on the curtain frame at a position corresponding to the rear side of the insulation ring bag. A fixing seat connected to the hanging beam is provided at the upper and lower ends of the curtain frame. A card frame is clamped on the curtain frame, and two lock slots are provided at the top and bottom of the card frame. A first lock tongue is hinged on the card frame at a position corresponding to each lock slot through a pin shaft. Two clamping holes are provided on both sides of the card frame, and a synchronous clamping mechanism matching the clamping holes is installed in the curtain frame.

[0005] The beneficial effects of the present invention are: 1. The present invention realizes multiple functions such as shading, lighting, protection, ventilation and heat insulation by arranging sunshade area, light-transmitting area, protection area, ventilation area and air-filled bag area on the curtain belt. The sunshade area can block direct sunlight and reduce indoor temperature. The light-transmitting area can provide natural light and create a comfortable environment. The protection area can resist external impact. The ventilation area ensures air circulation and prevents mosquitoes from entering. The air-filled bag area enhances the heat insulation effect after inflation, meeting different environments and usage requirements and comprehensively improving the comprehensive performance of the curtain wall.

[0006] 2. The present invention uses an air pump to supply air to the insulation ring bag and the inflatable bag area, and cooperates with the air pressure probe and the pressure relief valve to intelligently monitor and control the air pressure to ensure the safe and stable operation of the system. After the inflatable bag area and the insulation ring bag are inflated, the indoor and outdoor heat exchange is effectively reduced, the thermal insulation performance is improved, and the building energy consumption is reduced. At the same time, the air pump and the retracting system can be controlled by the control unit according to the indoor and outdoor temperatures to flexibly adjust the insulation effect.

[0007] 3. The ventilation assembly of the present invention comprises an inner air guide chamber, an outer air guide chamber, a one-way wind plate and a ventilation mesh. In summer, outside air enters the inner air guide chamber through the ventilation area and is discharged through the outer air guide chamber and the ventilation mesh, taking away indoor heat and reducing the use of air conditioning. In winter, the ventilation volume can be appropriately adjusted to keep the air fresh while avoiding excessive heat loss. The one-way wind plate prevents air backflow, ensuring smooth ventilation, improving indoor comfort and the energy-saving performance of the curtain wall.

[0008] 4. The existing curtain wall fixing structure is not stable enough, and the installation and disassembly are not convenient enough. The fixing seat of the present invention is provided with a hanging groove that cooperates with the hanging beam to preliminarily fix the position of the curtain frame. The first lock tongue and the lock groove are further fixed by bolts. The positioning block and the positioning groove ensure the accurate installation position. The synchronous clamping mechanism drives the synchronous shaft to rotate, driving the screw rod to clamp the clamp frame, realizing one-button fixing and one-button disassembly. At the same time, the second lock tongue is engaged with the card slot to enhance the fixing effect. This fixing structure is both stable and easy to install and disassemble, which improves installation efficiency, reduces installation cost, and ensures the safety and stability of the curtain wall during long-term use.

[0009] On the basis of the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, the rewinding system includes two winding rollers and two guide rollers rotatably connected to the curtain frame. Two drive motors are installed on the side of the curtain frame. The output shaft ends of the two drive motors are fixedly connected to the two winding rollers respectively. The two ends of the curtain belt are fixedly installed on the two winding rollers respectively. The two guide rollers are both transmission-connected to the curtain belt. Two symmetrically arranged sealing brush strips that elastically fit the curtain belt are fixedly installed on the inner wall of the curtain frame.

[0011] The beneficial effect of adopting the above further solution is that before use, the drive motor is started, and the drive motor drives the winding roller to rotate, and the winding roller rolls up or down the curtain belt. In this way, the unfolding and retracting states of the curtain belt can be flexibly controlled. In actual application, when it is necessary to adjust the indoor light intensity, temperature or perform protection, the retraction system can be used to quickly switch between different functional areas on the curtain belt. Compared with the traditional curtain wall structure, the retraction system is simple to operate and efficient, and can accurately control the position of the curtain belt according to actual needs, thereby improving the functionality and practicality of the curtain wall. The sealing brush strip can prevent impurities such as dust and rainwater from entering the interior of the curtain frame, ensuring the cleanliness and normal operation of the internal structure and extending the service life of the curtain wall. During installation, the opening faces the outside and the glass panel is inside the room.

[0012] Furthermore, a ventilation flow channel is fixedly opened inside the roller, and the inner cavity of the inflatable bag area is connected to the ventilation flow channel through an air guide hose. An air distribution pipe is installed on the curtain frame, and an air pressure probe and a pressure relief valve are respectively installed on the air distribution pipe. The two ventilation flow channels and the inner cavity of the insulation ring bag are both connected to the ventilation flow channel. A control unit is installed on the side of the curtain frame, and the data end of the air pressure probe is connected to the data of the control unit.

[0013] The beneficial effect of adopting the above-mentioned further scheme is that, when in use, the air pump supplies air to the insulation ring bag and the inflatable bag area, the air pressure probe monitors the air pressure in the ventilation flow channel in real time, and transmits the data to the control unit. When the air pressure is too high, the pressure relief valve opens to relieve the pressure, ensuring the safe and stable operation of the system. The inner cavity of the inflatable bag area is connected to the ventilation flow channel of the roller through the air guide hose, so that the inflatable bag area can be inflated and deflated quickly and evenly. In terms of building thermal insulation, the inflatable bag area can enhance the thermal insulation effect of the curtain wall after inflation, reduce indoor and outdoor heat exchange, and the thermal insulation performance can be further improved after the insulation ring bag is inflated. Compared with the existing technology, this design can realize intelligent monitoring and control of air pressure, ensure the stable performance of the thermal insulation function, effectively improve the thermal insulation performance of the curtain wall, and reduce building energy consumption.

[0014] Furthermore, the sunshade area is made of high-density polyethylene coated fabric material, the light-transmitting area is made of polycarbonate material, the protective area is made of aluminum alloy, the ventilation area is made of stainless steel mesh material, the mesh size of the stainless steel mesh is 2 mm to 5 mm, and the inflatable bag area is made of chloroprene rubber composite material. The longitudinal lengths of the sunshade area, light-transmitting area, protective area, ventilation area and inflatable bag area are the same.

[0015] The beneficial effect of adopting the above-mentioned further scheme is that the sunshade area adopts high-density polyethylene coated fabric material, which has good shading performance, can effectively block direct sunlight, reduce indoor temperature, and reduce energy consumption of air conditioners and other refrigeration equipment; the polycarbonate material in the light-transmitting area has good light transmittance, and can provide sufficient natural light when lighting is needed, creating a comfortable indoor environment; the aluminum alloy material in the protection area has high strength, can withstand the impact of external objects, and protect the curtain wall and indoor safety; the stainless steel wire mesh material in the ventilation area has a mesh size of 2 mm to 5 mm, which can not only ensure air circulation, but also prevent mosquitoes from entering the room; the neoprene composite material in the inflatable bag area has good flexibility and sealing, and can enhance the thermal insulation effect of the curtain wall after inflation; and the functional areas are the same length, which facilitates the unified operation and control of the retracting system. Compared with the traditional single-material curtain wall, this multi-material combination design has more diversified functions, can meet different environments and usage requirements, and comprehensively improves the comprehensive performance of the building's thermal insulation curtain wall.

[0016] Furthermore, each photovoltaic louver unit includes a transparent protective layer, a photovoltaic cell layer and a transparent support layer arranged in sequence from the outside to the inside. The transparent protective layer is made of polymethyl methacrylate, and the thickness of the transparent protective layer is 0.5mm to 1.5mm. The photovoltaic cell layer is composed of amorphous silicon thin-film solar cells. The transparent support layer is a glass fiber reinforced polycarbonate board, and the thickness of the transparent support layer is 1mm to 2mm.

[0017] The beneficial effect of adopting the above-mentioned further scheme is that, when in use, the transparent protective layer of the photovoltaic louver unit can protect the internal photovoltaic cell layer and transparent support layer to prevent them from being eroded and damaged by the external environment. The thickness of the transparent protective layer made of polymethyl methacrylate is between 0.5mm and 1.5mm, which can not only ensure good light transmittance but also have a certain strength. The photovoltaic cell layer is composed of amorphous silicon thin-film solar cells, which can convert solar energy into electrical energy to provide power support for part of the curtain wall equipment, achieve energy self-sufficiency, and reduce the energy consumption of the building. The transparent support layer is made of glass fiber reinforced polycarbonate board with a thickness of 1mm to 2mm, which provides a stable support structure for the photovoltaic cell layer. Compared with traditional blinds, this photovoltaic louver unit not only has the function of adjusting light and ventilation, but also can realize the collection and utilization of solar energy, improve the energy utilization efficiency of the curtain wall, and conform to the development concept of green buildings.

[0018] Furthermore, the ventilation assembly includes an inner air guide chamber opened in the curtain frame and arranged between the louver frame and the glass transparent plate, two symmetrically arranged outer air guide chambers are opened inside the curtain frame, both of the outer air guide chambers are connected to the inner air guide chamber, and a one-way wind plate is provided at the connection between the two outer air guide chambers and the inner air guide chamber, and two ventilation mesh surfaces are provided on the back of the curtain frame, and ventilation mesh holes connected to the inner air guide chamber are equidistantly opened on the two ventilation mesh surfaces.

[0019] The beneficial effect of adopting the above-mentioned further scheme is that, during use, when the indoor ventilation is needed, the outside air enters the inner air guide chamber through the ventilation area, and the one-way wind plate at the connection between the outer air guide chamber and the inner air guide chamber can prevent air backflow, ensure the smoothness of ventilation, and finally make the airflow of the inner air guide chamber flow into the outer air guide chamber in one direction, and the airflow entering the outer air guide chamber is finally discharged through the ventilation mesh. In summer, ventilation can take away indoor heat, lower the indoor temperature, reduce the frequency of air conditioning use, and achieve energy conservation and emission reduction. In winter, the ventilation volume can be appropriately adjusted to keep the indoor air fresh while avoiding excessive heat loss. Compared with traditional ventilation methods, the ventilation component is reasonably designed and has good ventilation effect. It can flexibly adjust the ventilation volume according to the season and actual needs, thereby improving indoor comfort and enhancing the energy-saving performance of the building's thermal insulation curtain wall.

[0020] Furthermore, the fixing seat is provided with two hanging slots that cooperate with the hanging beam, each of the first lock tongues and each of the lock slots is provided with multiple screw holes, a plurality of positioning blocks are fixedly provided on the card frame, and a positioning slot is provided on the curtain frame corresponding to the position of each positioning block.

[0021] The beneficial effect of adopting the above further solution is that when installing the curtain wall, the hanging beam is clamped into the hanging groove of the fixing seat to preliminarily fix the position of the curtain frame. By installing bolts in the positioning screw holes of the first locking tongue and the locking groove, the connection between the clamping frame and the curtain frame can be further fixed to prevent the curtain wall from loosening during use. The positioning block on the clamping frame cooperates with the positioning groove on the curtain frame to accurately control the installation position of the clamping frame, thereby ensuring the accuracy and stability of the curtain wall installation. This design makes the installation of the curtain wall more convenient and quick, the connection more firm and reliable, improves the installation efficiency, reduces the installation cost, and at the same time ensures the safety and stability of the curtain wall during long-term use, reducing the safety hazards caused by improper installation. Moreover, this fixing structure enables the screen frame to be disassembled both indoors and outdoors, thereby improving the convenience of installing and disassembling the screen frame; The two gears are connected to each other through the first and second gears, and the two gears are connected to each other through the second gears, and the two gears are connected to each other through the second gears.

[0022] The beneficial effect of adopting the above further scheme is that when it is necessary to fix the card frame, the synchronous shaft is driven to rotate, and the synchronous shaft drives the gear shaft to rotate through the third bevel gear, and the first bevel gear at the bottom end of the gear shaft is connected with the second bevel gear on the first screw rod and the second screw rod, so that the first screw rod and the second screw rod rotate synchronously, and the positive thread section and the negative thread section on the first screw rod and the second screw rod drive the transmission seat to move, and the transmission seat pushes the clamp to move toward the clamping hole through the connecting rod to achieve clamping and fixing of the card frame. The synchronous clamping mechanism can clamp the clamping holes on both sides of the card frame at the same time, ensuring the stability and reliability of the clamping. Compared with the traditional fixing method, this synchronous clamping mechanism is easy to operate and has a good fixing effect, which can effectively prevent the card frame from loosening, improve the stability of the overall structure of the curtain wall, and ensure that the curtain wall can work normally in various environments; This method is also convenient for fixing and can achieve one-button fixing and one-button removal, thereby improving the installation and removal efficiency of the curtain frame.

[0023] Furthermore, the synchronous clamping mechanism also includes four card slots opened on the card frame, each of the first screw rods and each second screw rod is equipped with a second lock tongue engaged with the card slot, and both ends of the first screw rod and the second screw rod are equipped with a transmission nut.

[0024] The beneficial effect of adopting the above-mentioned further scheme is that when the synchronous clamping mechanism is working, the second locking tongues on the first screw rod and the second screw rod are engaged with the card grooves on the card frame, which can further enhance the fixing effect of the card frame, prevent the screw rod from axial displacement during rotation, and improve the stability of clamping. The transmission nuts are installed at both ends of the first screw rod and the second screw rod, which can limit the screw rod and ensure that the screw rod rotates within the normal working range. At the same time, it is also convenient for the installation and disassembly of the screw rod. This design further improves the function of the synchronous clamping mechanism, makes the curtain wall fixation more firm and reliable, extends the service life of the curtain wall, and reduces maintenance costs.

[0025] Furthermore, the end faces of the curtain frame are respectively installed with light intensity sensors, wind and rain sensors and temperature sensors. The light intensity sensor is used to monitor the external light intensity and transmit the data to the control unit, the temperature sensor is used to monitor the indoor and outdoor temperatures and transmit the data to the control unit, and the wind and rain sensor is used to monitor the external wind and rain conditions and transmit the data to the control unit. The control unit is electrically connected to the light intensity sensor, temperature sensor, wind and rain sensor, retracting system, air pump, ventilation area and protection area respectively. The control unit receives sensor data and controls the action of each component according to preset logic and thresholds to realize intelligent switching of sunshade area, light-transmitting area, protection area, ventilation area and airbag area.

[0026] The beneficial effect of adopting the above-mentioned further scheme is that the light intensity sensor monitors the external light intensity in real time, the temperature sensor monitors the indoor and outdoor temperatures, and the wind and rain sensor monitors the external wind and rain conditions, and transmits these data to the control unit. The control unit controls the actions of components such as the retracting system, air pump, ventilation area and protection area according to preset logic and thresholds. For example, when the light intensity is too high, the control unit controls the retracting system to unfold the sunshade area; when the indoor temperature is too high, the ventilation area is started for ventilation and cooling, and the air pump can be controlled to inflate the airbag area to enhance the thermal insulation effect; when windy and rainy weather is detected, the ventilation area is folded up and the protection area is unfolded. The system realizes intelligent switching of various functional areas of the curtain wall without manual operation, and can automatically adjust the curtain wall status according to changes in the external environment, thereby improving the intelligence and ease of use of the curtain wall. Compared with traditional curtain walls, it greatly improves the user experience, is more energy-saving and environmentally friendly, and effectively reduces building energy consumption.

[0039] During use, when the room needs ventilation, the outside air enters the inner air guide chamber 20 through the ventilation area 304, and the one-way wind plate 38 at the connection between the outer air guide chamber 21 and the inner air guide chamber 20 can prevent air backflow, ensure the smoothness of ventilation, and finally make the airflow of the inner air guide chamber 20 flow into the outer air guide chamber 21 in one direction, and the airflow entering the outer air guide chamber 21 is finally discharged through the ventilation mesh. In summer, ventilation can take away indoor heat, lower the indoor temperature, reduce the frequency of air conditioning use, and achieve energy conservation and emission reduction. In winter, the ventilation volume can be appropriately adjusted to keep the indoor air fresh while avoiding excessive heat loss. Compared with traditional ventilation methods, the ventilation component is reasonably designed and has good ventilation effect. It can flexibly adjust the ventilation volume according to the season and actual needs, thereby improving indoor comfort and enhancing the energy-saving performance of the building's thermal insulation curtain wall.

[0040] Two hanging slots 23 are provided on the fixing seat 11 to cooperate with the hanging beam 2. Multiple screw holes are provided on each first locking tongue 14 and each locking slot 13. Multiple positioning blocks 24 are fixedly provided on the card frame 12. A positioning slot 25 is provided on the curtain frame 1 corresponding to the position of each positioning block 24.

[0041] When installing the curtain wall, the hanging beam 2 is inserted into the hanging groove 23 of the fixing seat 11 to preliminarily fix the position of the curtain frame 1. By installing bolts in the positioning screw holes of the first locking tongue 14 and the locking groove 13, the connection between the card frame 12 and the curtain frame 1 can be further fixed to prevent the curtain wall from loosening during use. The positioning block 24 on the card frame 12 cooperates with the positioning groove 25 on the curtain frame 1 to accurately control the installation position of the card frame 12, thereby ensuring the accuracy and stability of the curtain wall installation. This design makes the installation of the curtain wall more convenient and quick, the connection more firm and reliable, improves the installation efficiency, reduces the installation cost, and at the same time ensures the safety and stability of the curtain wall during long-term use, thereby reducing the safety hazards caused by improper installation. Moreover, this fixing structure enables the screen frame 1 to be disassembled both indoors and outdoors, thereby improving the convenience of installing and disassembling the screen frame 1; The synchronous clamping mechanism includes two first screw rods 26 and two second screw rods 27 that are rotatably connected to the curtain frame 1. The two first screw rods 26 are linked by a first belt, and the two second screw rods 27 are linked by a second belt. A synchronous shaft 28 and two gear shafts 29 are rotatably installed on the curtain frame 1. The bottom ends of the two gear shafts 29 are fixedly installed with first bevel gears. A first screw rod 26 and a second screw rod 27 are fixedly installed with second bevel gears. The two first bevel gears are respectively connected to the two second bevel gears. Two third bevel gears are installed on the synchronous shaft 28. A fourth bevel gear is fixedly installed on the top of the gear shaft 29, and the two fourth bevel gears are respectively connected to the two third bevel gears for transmission. Each first screw rod 26 and each second screw rod 27 are provided with a positive thread segment and a negative thread segment. Each first screw rod 26 and each second screw rod 27 are connected to a clamping module, and the clamping module includes two transmission seats 30 and a clamp 31 that cooperates with the clamping hole 15. The two transmission seats 30 are respectively connected to the positive thread segment and the negative thread segment at the corresponding position, and a connecting rod 32 is hinged between the clamp 31 and the two transmission seats 30.

[0042] When it is necessary to fix the card frame 12, the synchronous shaft 28 is driven to rotate, and the synchronous shaft 28 drives the gear shaft 29 to rotate through the third bevel gear. The first bevel gear at the bottom end of the gear shaft 29 is connected to the second bevel gear on the first screw rod 26 and the second screw rod 27, so that the first screw rod 26 and the second screw rod 27 rotate synchronously. The positive thread section and the negative thread section on the first screw rod 26 and the second screw rod 27 drive the transmission seat 30 to move, and the transmission seat 30 pushes the clamp 31 to move toward the clamping hole 15 through the connecting rod 32 to achieve clamping and fixing of the card frame 12. This synchronous clamping mechanism can clamp the clamping holes 15 on both sides of the card frame 12 at the same time, ensuring the stability and reliability of the clamping. Compared with the traditional fixing method, this synchronous clamping mechanism is easy to operate and has a good fixing effect. It can effectively prevent the card frame 12 from loosening, improve the stability of the overall structure of the curtain wall, and ensure that the curtain wall can work normally in various environments. Moreover, this method is convenient for fixing and can realize one-key fixing and one-key disassembly, thereby improving the installation and disassembly efficiency of the screen frame 1.

[0043] The synchronous clamping mechanism also includes four card slots 33 opened on the card frame 12. Each first screw rod 26 and each second screw rod 27 is equipped with a second lock tongue 34 that is engaged with the card slot 33. A transmission nut is installed at both ends of the first screw rod 26 and the second screw rod 27.

[0044] When the synchronous clamping mechanism is working, the second locking tongue 34 on the first screw rod 26 and the second screw rod 27 is engaged with the card groove 33 on the card frame 12, which can further enhance the fixing effect of the card frame 12, prevent the screw rod from axial displacement during rotation, and improve the stability of clamping. The transmission nut is installed at both ends of the first screw rod 26 and the second screw rod 27, which can limit the screw rod and ensure that the screw rod rotates within the normal working range. At the same time, it is also convenient for the installation and disassembly of the screw rod. This design further improves the function of the synchronous clamping mechanism, makes the curtain wall fixation more firm and reliable, extends the service life of the curtain wall, and reduces maintenance costs.

[0045] The end faces of the curtain frame 1 are respectively installed with a light intensity sensor 35, a wind and rain sensor 36 and a temperature sensor 37. The light intensity sensor 35 is used to monitor the external light intensity and transmit the data to the control unit 19. The temperature sensor 37 is used to monitor the indoor and outdoor temperatures and transmit the data to the control unit 19. The wind and rain sensor 36 is used to monitor the external wind and rain conditions and transmit the data to the control unit 19. The control unit 19 is electrically connected to the light intensity sensor 35, the temperature sensor 37, the wind and rain sensor 36, the retracting system, the air pump 9, the ventilation area 304 and the protection area 303. The control unit 19 receives the sensor data and controls the operation of each component according to the preset logic and threshold value to realize the intelligent switching of the sunshade area 301, the light-transmitting area 302, the protection area 303, the ventilation area 304 and the inflatable bag area 305.

[0046] The light intensity sensor 35 monitors the external light intensity in real time, the temperature sensor 37 monitors the indoor and outdoor temperatures, and the wind and rain sensor 36 monitors the external wind and rain conditions, and transmits these data to the control unit 19. The control unit 19 controls the actions of the retracting system, the air pump 9, the ventilation area 304 and the protection area 303 according to the preset logic and threshold. For example, when the light intensity is too high, the control unit 19 controls the retracting system to unfold the sunshade area 301; when the indoor temperature is too high, the ventilation area 304 is started for ventilation and cooling, and the air pump 9 can be controlled to inflate the airbag area 305 to enhance the thermal insulation effect; when windy and rainy weather is detected, the ventilation area 304 is folded up and the protection area 303 is unfolded. The system realizes the intelligent switching of various functional areas of the curtain wall without manual operation, and can automatically adjust the curtain wall status according to changes in the external environment, thereby improving the intelligence and ease of use of the curtain wall. Compared with traditional curtain walls, it greatly improves the user experience, is more energy-saving and environmentally friendly, and effectively reduces building energy consumption.
