Description

Technical Field

[0001] The present invention relates to the technical field of building skin systems, and particularly to a flexible membrane structure building adaptive skin system and an integration method that dynamically respond to user and environmental requirements. Background Art

[0002] The building skin plays a crucial role in the overall performance of a building and the dimension of user experience. Its initial function mainly focuses on the protection of the building's internal structure and reducing the adverse effects of external natural factors. With the continuous evolution of building technology, the building skin has been promoted to develop in the direction of integrating aesthetics and functionality. The building skin is a medium for heat and mass transfer between the indoor and outdoor environments, and is an important system for reducing building energy consumption, improving the green performance of buildings, and creating a healthy living environment. The building adaptive skin further improves the response accuracy and flexibility of the building skin system to dynamic requirements, and has become a forward-looking field in the development of building envelopes in the digital age.

[0003] However, in this development process, early building skin designs were mostly based on single functional requirements or pure aesthetic considerations, lacking the coordinated response to the objective environment and user needs. Although existing adaptive skin systems have achieved a certain degree of response to the environment, they have defects in data collection, adjustment accuracy, and aesthetic integration. The data collection is not accurate and comprehensive enough to obtain real-time information such as user status and the characteristics of the indoor and outdoor environments of the building; the adjustment accuracy is limited, making it difficult to achieve fine control of the building skin and unable to precisely meet the personalized needs of different regions and different users. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems in the prior art, and a flexible membrane structure building adaptive skin system and an integration method that dynamically respond to user and environmental requirements are proposed. The system realizes real-time perception and precise coordinated response to environmental data and user needs by integrating multiple modules working together, effectively improving the indoor environmental quality of the building, optimizing the building energy utilization efficiency, and at the same time creating a dynamic aesthetic building facade effect.

The signal input end of the deformation control module is communicatively connected to the output end of the data acquisition module. After receiving the motion instruction from the deformation control module, the motion execution module changes. The built-in components drive the rod system to complete linkage through the rotation of the servo motor 1, and finally the flexible membrane structure changes according to the algorithm result rule, and the ventilation and lighting are adjusted through the tensile expansion and contraction deformation of the flexible membrane structure.

[0006] Further, a number of motion execution modules are equipped with m*n servo motors 1 and driving gears 2 installed on the rotating shafts of the servo motors 1.

[0008] Further, the flexible membrane structure includes a flexible membrane 6 and nylon fastener belts 7 that are flexibly connected.

[0011] Further, the magnitude of the rotation amplitude of the servo motor 1 directly affects the forward and backward movement length of the driven rack 3. Each servo motor 1 will perform a fine angle rotation respectively according to the control instruction generated by the deformation control module. The rotation accuracy can reach ±0.1 degree, and the response time does not exceed 1000 milliseconds, so as to accurately control the movement direction and length of the rack, thereby driving the accurate deformation of the lightweight telescopic aluminum strip 5, and realizing the precise regulation of the deformation of the flexible film 6; the flexible film 6 in each area is individually tensioned and controlled, so as to realize the personalized ventilation, lighting and behavior requirements of each area.

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] In conjunction with Figures 1-9, the present invention provides a flexible membrane structure building adaptive skin system that dynamically responds to user and environmental requirements. The adaptive skin system includes a data acquisition module, a deformation control module, a plurality of motion execution modules, and a flexible membrane structure. After the motion execution module is connected to the flexible membrane structure, it is bolted to the channel steel column by an L-shaped steel, and is firmly fixed to the outer side of the building facade through a transition piece and an embedded part. Moreover, the fixed flexible membrane structure is welded to the embedded part on the building facade by a lightweight aluminum alloy rod as an auxiliary fixing method. Specifically, a plurality of motion execution modules are tightly connected to the flexible membrane structure by a nylon fastener belt 7, bolted to the channel steel column 13 by an L-shaped steel 12, and the channel steel column 13 is fixed to the outer side of the building facade 14 through a transition piece and an embedded part. A servo motor 1 is installed on the motion execution module, and the control end of the servo motor 1 is electrically connected to the signal output end of the deformation control module in a wired manner. The signal input end of the deformation control module is communicatively connected to the output end of the data acquisition module. After receiving the motion instruction from the deformation control module, the motion execution module changes. The built-in components drive the rod system to complete linkage through the rotation of the servo motor 1, and finally the flexible membrane structure changes according to the algorithm result rule, and the ventilation and lighting are adjusted through the tensile expansion deformation of the flexible membrane structure.

[0036] A plurality of motion execution modules are equipped with m*n servo motors 1 and driving gears 2 installed on the rotating shafts of the servo motors 1. The servo motors 1 are arranged in a plane parallel to the building facade according to the horizontal distance x and the vertical distance y. Each row of motion execution modules is n, and each column of motion execution modules is m. m and n are arbitrary natural numbers, and the values of m and n can be adjusted according to the building facade. That is, the value range of m is determined according to the building facade height and the required adjustment accuracy, and the value range of n is determined according to the building facade width and the adjustment area division. The horizontal distance x is determined according to the expected tensile effect, and the value range is 0.2-0.4m. The vertical distance y is set with an initial value according to the operating safety distance between the rods and the length of the rods themselves. In the present invention, the distance y is set with an initial value according to the operating safety distance of not less than 0.25m between the rods.

[0037] Both the driving gear and the driven rack are made of lightweight aluminum. The driving gear has 36 teeth, and the pitch of the driven rack is matched accordingly. The length is determined within 0.3 - 0.5 m according to the actual transmission requirements. The servo motor is fixed to the plastic card holder by bolts, and the plastic card holder is connected to the L-shaped steel. The driven rack is placed in the sliding groove of the plastic card holder and meshes with the driving gear. After receiving the motion instruction, the servo motor rotates, driving the driving gear to rotate and then driving the driven rack to reciprocate back and forth. Specifically, the servo motor 1 is fixed to the plastic card holder 10 by bolts, and the plastic card holder 10 is fixedly connected to the L-shaped steel 12. The driven rack 3 is placed in the sliding groove of the plastic card holder 10 and meshes with the driving gear 2. A lightweight aluminum ring 4 with a square hole with rounded corners is welded to the end of the driven rack 3, and a lightweight telescopic aluminum strip 5 is fixed to the lightweight aluminum ring 4 by bolts. The cross-sectional shape of the sliding groove of the plastic card holder meshes with the cross-sectional shape of the driven rack, and the overlapping part is 0.15 m in length of the sliding groove of the plastic card holder. Driven by the servo motor and the driving gear, the driven rack reciprocates back and forth in the sliding groove, and the friction coefficient between the two is 0.1. A lightweight aluminum ring with a square hole with rounded corners is welded to the end of the driven rack, with an inner diameter of 3 * 70 mm and an outer diameter of 5 * 80 mm. A lightweight telescopic aluminum strip is fixed to the lightweight aluminum ring by bolts. The cross-sectional dimension of the lightweight telescopic aluminum strip is 2 * 65 mm, and it has its own telescopic elasticity. It can deform in a curve in the X-Y plane according to the end point fixed to the lightweight aluminum ring. When there is a position difference in the X direction between two adjacent driven racks, the fixed points of the lightweight telescopic aluminum strip and the lightweight aluminum ring will change in the X direction, driving the lightweight telescopic aluminum strip between the two fixed points to be tensioned. The curve in the X-Y plane will change from the initial curve to a new curve in the X-Y plane. As the driven rack continuously transmits power, it drives the lightweight telescopic aluminum strip to move continuously, and the plane curve changes accordingly.

[0038] The flexible membrane structure includes a flexible membrane 6 and a Velcro tape 7 which are flexibly connected. The Velcro tape 7 at the edge of the flexible membrane 6 is continuously arranged and connected and fixed to the outer aluminum frame. One end of several lightweight aluminum alloy rods is welded to the aluminum frame rod 8, and the other end is welded and fixed to the building 14 through embedded parts; in the flexible membrane 6, the Velcro tape 7 fixed on the inner side is distributed in a dot pattern, and the Velcro tape 7 is connected to the lightweight aluminum ring 4 and is distributed in a wavy pattern along the edge of the membrane surface; the flexible membrane 6 contacts the lightweight telescopic aluminum strip 5 without being fixed, and generates corresponding dynamic changes according to the characteristics of the aluminum strip itself, and will not affect the deformation effect due to too large or too small friction force. Specifically, the flexible membrane structure includes a flexible membrane and a Velcro tape which are flexibly connected; the light transmittance of the flexible membrane material is between 35% and 65%, with semi-transparency, and its light transmission property changes with the tension degree to realize light environment adjustment; the Velcro tape at the edge of the flexible membrane is continuously arranged and connected to the outer aluminum frame, and one end of several lightweight aluminum alloy rods is welded to the aluminum frame rod, and the other end is welded to the building through embedded parts. The Velcro tape fixed on the inner side of the flexible membrane is distributed in a dot pattern, connected to the lightweight aluminum ring and distributed in a wavy pattern along the edge of the membrane surface. The flexible membrane has strong elasticity and plasticity, and has large changes in light transmission and ventilation characteristics after tensioning. After the flexible membrane and the lightweight aluminum ring are fixed by Velcro, the driven rack drives the lightweight aluminum ring at the end to move back and forth in the X direction, and the contact point directly tensions to cause the appearance deformation of the flexible membrane; moreover, the lightweight telescopic aluminum strip in spatial contact with the flexible membrane serves as the support framework of the flexible membrane, and the lightweight telescopic aluminum strip drives the flexible membrane to supplement the deformation in appearance during the process of transmission deformation, and the form change of the flexible membrane is rich.

[0039] The data acquisition module includes an indoor illuminance sensor 15 arranged at the user's working plane in the building 14 and n distance sensors 16 in the building 14 and in the vertical plane of the skin; the measurement accuracy of the indoor illuminance sensor 15 is ±0.1 lux, and the measurement range is 0 - 1000 lux, which can accurately collect indoor light intensity data; n distance sensors 16 are installed at intervals of 1 m in the building and at a height of 1 m from the ground in the vertical plane of the skin; the measurement accuracy of the distance sensor 16 is ±0.01 m, and the measurement range is 0 - 10 m, which can accurately obtain the distance information between the user and the skin and provide data support for the precise adjustment of the system.

[0040] The deformation control module is communicatively connected to the data acquisition module, and is configured to receive indoor illuminance data and user distance data, analyze and judge the environmental lighting conditions and the user's state according to a preset algorithm, and generate control instructions. The deformation control module includes a data processing unit and a control instruction generation unit. The data processing unit is configured to perform preprocessing such as filtering and denoising on the collected indoor illuminance data and user distance data, and input the preprocessed data into a preset algorithm for analysis. The control instruction generation unit is configured to generate control instructions according to the processing results. The control instructions include precise control parameters such as the rotation angle and rotation direction of the servo motor 1. Specifically, the deformation control module is communicatively connected to the data acquisition module via Bluetooth, and the communication protocol uses Bluetooth 4.0. It receives indoor illuminance data and user distance data, and analyzes and judges them using a preset algorithm. This algorithm is established based on a large amount of experimental data and theoretical research, comprehensively considers various factors, and generates precise control instructions through complex calculations and logical judgments. The control instructions include parameters such as the rotation angle and rotation direction of the servo motor.

[0041] The magnitude of the rotation amplitude of the servo motor 1 directly affects the forward and backward movement length of the driven rack 3. Each servo motor 1 will perform fine-angle rotation respectively according to the control instructions generated by the deformation control module. The rotation accuracy can reach ±0.1 degrees, and the response time does not exceed 1000 milliseconds, so as to accurately control the movement direction and length of the rack, and drive the accurate deformation of the lightweight telescopic aluminum strip 5 accordingly, realizing the precise regulation of the deformation of the flexible film 6. The control degree of the servo motor 1 in each area can be adjusted immediately and accurately, and the flexible film 6 in each area is controlled separately for tensioning, so as to realize the personalized ventilation, lighting and behavior requirements of each area.

[0042] The working principle and control process of the described building adaptive skin system are as follows: The data acquisition module continuously collects indoor illuminance data and user distance data, and transmits them through communication to the deformation control module. The data processing unit in the deformation control module analyzes the data and discriminates the illuminance into three categories: low light (illuminance < 150 lux), normal light (150 - 450 lux), and strong light (> 450 lux); it discriminates the distance between the user and the nearest facade into two categories: short distance (distance < 1 m), long distance (distance ≥ 1 m). The control instruction generation unit generates control instructions according to a preset algorithm. The algorithm adopts a hierarchical control logic: it gives priority to responding to the user distance signal. When the user enters within 1 m, the generated instructions will control several servo motors in the control area to finally drive the membrane to sink inward to form a shading area, and at the same time adjust the sinking depth (10 - 30 cm) and the membrane inclination angle (0° - 45°) in combination with the illuminance. When the user is far from the facade, the facade shape depression and inclination angle (0 - 30 degrees) are adjusted according to the indoor illuminance; the control instructions are electrically transmitted through wires to the individual servo motors of the motion execution module. The individual servo motors rotate precisely at corresponding angles respectively, with a rotation accuracy of up to ±0.1 degree and a response time of no more than 1000 milliseconds. Each servo motor drives the active gear to rotate, and then drives the driven rack meshing with the active gear to move back and forth along the X direction in the X - Y plane. The movement distance is precisely controlled by the rotation angle of the servo motor; the driven rack drives the lightweight telescopic aluminum strip inside the lightweight aluminum ring welded at the end to move in the X - Y plane. The fixed point of the lightweight telescopic aluminum strip and the driven rack is stressed and moves in the X direction. Each lightweight telescopic aluminum strip expands and contracts in the X - Y plane to perform corresponding curve deformations; the lightweight telescopic aluminum strip contacts the flexible membrane, and a traction or thrust is generated at the fixed point between the two to form a force - generating point for deformation. In the linear contact area, the lightweight telescopic aluminum strip serves as a support framework to guide the flexible membrane structure to undergo tensile expansion and contraction changes. During the tensile process of the flexible membrane, its own thickness and texture density change, thereby generating changes in the characteristics of light shading and ventilation, so as to achieve the functions of facade light adjustment, ventilation, and heat insulation to adapt to environmental changes and user needs; moreover, because the control instructions can independently control the tension of the flexible membrane in the area, it can meet the personalized ventilation, lighting, and behavior requirements of each area.

[0043] The present invention also proposes an integration method based on the described building adaptive skin system. The method includes the following steps:

[0044] Install the fixing structure: Embed channel - shaped steel columns 13 on the outer side of the building facade. The spacing is determined according to the building structure strength and the load of the skin system; bolt - connect the L - shaped steel 12 to the channel - shaped steel column 13 through a connecting piece to ensure rust prevention treatment at the connection; fix the plastic card holder 10 on the L - shaped steel 12, adjust the horizontal distance x to 0.3 m and the vertical distance y to 0.3 m to form an m×n servo - motor matrix layout;

[0045] Assembly of the motion execution module: The servo motor 1 is vertically fixed on the plastic card holder 10 by bolts to ensure the precise meshing of the driving gear 2 and the driven rack 3; the lightweight aluminum ring 4 is welded to the end of the driven rack 3 and bolted to the lightweight telescopic aluminum bar 5 to form a continuous X-Y plane transmission framework;

[0046] Laying of the flexible membrane structure: The edge of the flexible membrane 6 is fixed to the aluminum frame through the continuous nylon fastener tape 7; the aluminum frame is welded to the building embedded parts through lightweight aluminum alloy rods to ensure uniform initial tension of the flexible membrane 6; the nylon fastener tapes 7 distributed in a dot pattern on the inner side of the flexible membrane 6 are connected to the lightweight aluminum ring 4 to form a wavy edge;

[0047] Integration of the data acquisition and deformation control module: Install the indoor illuminance sensor 15 at the height of the user's working plane (1.2 m), with one sensor installed every 10 ㎡; install the distance sensor 16 at intervals of 1 m along the vertical direction of the building facade, with a height of 1 m from the ground; the deformation control module communicates with the sensors through the Bluetooth 4.0 protocol and presets a hierarchical control algorithm.

[0048] Taking the south facade of an office building as an example, the system is installed and tested:

[0049] Refer to Figure 1 , the flexible membrane structure building adaptive skin system that dynamically responds to user and environmental requirements has a preset initial state, that is, the initial telescopic position of the driven rack in the X-Y plane is zero, and the relative displacement of the driven rack in the groove of the plastic base is also zero; before each adjustment of the flexible membrane form change, the control instruction generation unit in the deformation control module will use the relative position of the current driven rack and the initial state as part of the calculation data and bring it into the preset algorithm to generate control instructions.

[0050] Refer to Figures 1-5 , the present invention proposes a flexible membrane structure building adaptive skin system that dynamically responds to user and environmental requirements, which mainly consists of a data acquisition module, a deformation control module, several motion execution modules and a flexible membrane structure. The present invention adjusts the external form of the flexible membrane structure by receiving indoor illuminance data and user distance data in real time, so as to realize the adjustment of the building indoor light and heat environment and the interaction with users by the building adaptive skin. In this embodiment, a total of 24 motion execution modules are set in the skin system, which are closely arranged in four rows, with 6 control modules in each row; number the motion execution modules of the system, with the letter numbers from left to right being A-F and the number numbers from top to bottom being 1-4, and the motion execution module numbers are the combination of letters and numbers, that is, A1 to F4.

[0051] Refer to Figure 6, in this embodiment, the epidermal system is in the initial state. The indoor illuminance data collected in the first time period is 200 lux, and the distance between the user and the third column of motion execution modules is 0.8 m. The data is transmitted to the deformation control module. The control instruction generation unit calculates according to the prefabricated data processing method, determines that the current is a low-light environment and there are user activity characteristics in some areas, simulates the most appropriate adjustment method through the algorithm, and transmits it into the deformation control module.

[0052] Referring to Figure 6 , after the deformation control module issues a regulation instruction to the motion execution module, the servo motors in the B1, B3, C2, C4, D1, and D3 motion execution modules rotate clockwise by 720 degrees, and the driving gear drives the driven rack to move forward 0.25 m along the X-axis direction. The servo motors in the B2, B4, C1, C2, D2, and D4 motion execution modules remain stationary, and the driven rack does not change in the X-axis direction; the servo motors in the A1-A4 and E1-E4 motion execution modules rotate clockwise by 360 degrees, and the driving gear drives the driven rack to move forward 0.125 m along the X-axis direction. The servo motors in the F1-F4 motion execution modules remain stationary, and the driven rack does not change in the X-axis direction. The X coordinate of the driven rack changes in the X-Y plane, which causes the X coordinate of the connection point of the lightweight telescopic aluminum strip with its end fixed in the lightweight aluminum ring to change. The lightweight telescopic aluminum strip is stretched to different degrees at different positions, forming several different and special curves.

[0053] The lightweight telescopic aluminum strip contacts and supports the flexible membrane in space. Its shape change drives the flexible membrane to produce morphological changes in different regions, driving the flexible membrane to stretch in the region closer to the person to form the largest deformation region. The stretching depth of the flexible membrane is about 0.25 m, and the membrane surface inclination angle is 40°. At this time, the user can feel a greater ventilation effect of the flexible membrane, and the visual effect on the outside of the building reaches the best; the elevation area farther from the user stretches to form a moderate deformation region. The stretching depth of the flexible membrane is about 0.125 m, and the membrane surface inclination angle is 20°. At this time, the indoor users have less perception of the change in light, and the function of supplementing indoor light through the outside is less.

[0054] After the operation of the deformation control module is completed, the deformation control module continues to receive the measurement data transmitted by the data acquisition module, judges the data change through the built-in data processing unit, and transmits the processed data into the control instruction generation unit for the next regulation movement.

[0055] Referring to Figure 7, the data collected by the data acquisition module is 50 lux of light, and no one is close to the building facade. The control instruction generation unit calculates according to the current collected data and the relative relationship between the driven rack and the initial position, using a preset data processing method, determines that the current is a low-light environment and there are no user activity characteristics, simulates the most appropriate adjustment method through an algorithm, and transmits it to the deformation control module.

[0056] After receiving the regulation instruction, the deformation control module will regulate the operation of the servo motors in each independent motion execution module, and finally make the servo motors of A1-A4, C1-C4, and E1-E4 regulate the corresponding driven racks to move forward 0.25 m along the X-axis direction relative to the initial state, and the servo motors of B1-B4, D1-D4, and F1-F4 regulate the corresponding driven racks to be in the initial state; by the same principle as the previous step, the X coordinate of the joint point of the light telescopic aluminum strip fixed at the end of the driven rack in the light aluminum ring changes, and the different degrees of stretching of the light telescopic aluminum strip form a special curve, pushing the flexible film to deform in different areas, driving the flexible film to generate a large wavy shape on the entire facade. The stretching depth of the flexible film in each area is about 0.22 m, and the film surface inclination angle is 35°; at this time, the users indoors can clearly perceive the light source supplement outside the building.

[0057] After the operation of the deformation control module is completed, the deformation control module continues to receive the measurement data transmitted by the data acquisition module, and the transmitted and processed data enters the control instruction generation unit to judge the next regulation movement.

[0058] Refer to Figure 8 , the data collected by the data acquisition module arranged indoors in the building is 600 lux of light, and the distances between two users and the motion execution modules in the second and fifth columns are 0.65 m. The control instruction generation unit calculates according to the current collected data and the relative relationship between the driven rack and the initial position, using a preset data processing method, determines that the current is a strong light environment and there are user activity characteristics, simulates the most appropriate adjustment method through an algorithm, and transmits it to the deformation control module.

[0059] After receiving the regulation instruction, the deformation control module will regulate the operation of the servo motors in each independent motion execution module. Eventually, the servo motors of B1, B4, E1, and E4 will regulate the corresponding driven racks to move forward 0.25 m along the X-axis direction relative to the initial state. The servo motors of A1, A4, B2, B3, C1, C4, D1, D4, E2, E3, F1, and F4 will regulate the corresponding driven racks to move forward 0.15 m along the X-axis direction relative to the initial state. The servo motors of A2, A3, C2, C3, D2, D3, F2, and F3 will regulate the corresponding driven racks to be in the initial state. Based on the same principle as the previous step, the X coordinates of the intersection points of the lightweight telescopic aluminum bars with their ends fixed in the lightweight aluminum ring will change as the driven racks move. The different degrees of stretching of the lightweight telescopic aluminum bars form a special curve, which pushes the flexible membrane to deform in different areas. This drives the flexible membrane to form a large wavy shape on the entire facade. The stretching depth of the flexible membrane in each area where the user approaches is about 0.20 m, and the membrane surface inclination is 30°. At this time, users indoors can clearly perceive the light source outside the building and have a clearer outdoor view. The stretching depth of the flexible membrane in each area far from the user's approach is about 0.10 m, and the membrane surface inclination is 12°. At this time, users indoors have a weaker outdoor view, and less strong light indoors is exposed to the outside. After the operation of the deformation control module is completed, the deformation control module continues to receive the measurement data transmitted by the data acquisition module, and the processed data is transmitted to the control instruction generation unit to judge the next regulation movement.
