Description

Technical Field

[0001] This utility model belongs to the field of louvered glass technology, specifically relating to hollow louvered glass with intelligent dimming mechanism, and more particularly to a hollow louvered glass with intelligent dimming mechanism. Background Technology

[0002] Insulating louvered glass with intelligent dimming mechanism is an innovative energy-saving building material that integrates the traditional louvered curtain system into the cavity of the insulating glass, realizing the integrated design of sun shading and architecture.

[0003] In existing insulated louvered glass with intelligent dimming mechanisms, curved blades are used. This allows light to pass through when the glass is closed. When the curved blades are flipped closed, adjacent blades can only make line or point contact, and cannot form a continuous contact surface. This contact method inevitably leaves light-transmitting gaps between the blades. Specifically, the width of the light-transmitting gaps between the curved blades can be 0.5-2mm, resulting in a maximum light-blocking rate of only 85-90%. In addition, the internal environment of insulated glass is not constant. Temperature changes will cause the blades to expand and contract. In the high temperature environment of summer, aluminum-magnesium alloy blades can expand 0.3-0.5% in the length direction. This micro-deformation is enough to disrupt the original contact relationship and increase the light-transmitting gaps.

[0004] Therefore, how to avoid light-transmitting gaps when the curved blades are closed is a technical problem that urgently needs to be solved in this field.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0006] This disclosure provides at least one hollow louvered glass with an intelligent dimming mechanism to solve the technical problem of light transmission gaps when the curved blades are closed.

[0007] In a first aspect, embodiments of this disclosure provide a hollow venetian blind with an intelligent dimming mechanism, comprising: a hollow glass frame, wherein a driving structure is disposed inside the frame near the top; a venetian blind assembly disposed within the hollow glass frame by a pull cord, wherein the driving structure causes the venetian blind assembly to rise, fall, or rotate by retracting the pull cord; the venetian blind assembly comprises: a plurality of venetian slats, the surface of which is provided with protrusions and recesses; wherein, when adjacent venetian slats are closed, the protrusion of the lower venetian slat is adapted to be fitted into the recess of the upper venetian slat to achieve a tight fit between the venetian slats and prevent light from passing through gaps when closed; the protrusion includes a magnetic strip, the surface of which is covered with a rubber layer; and the thickness of the rubber layer is 1 / 4 to 1 / 2 of the thickness of the magnetic strip; the surface of the recess is coated with magnetic metal powder.

[0008] In one alternative embodiment, the protrusion is located on one side of the top edge of the louver, and the recess is located on the other side of the bottom edge of the louver.

[0009] In one optional embodiment, brightness sensors are evenly distributed on both sides of the inner wall of the hollow glass frame, and are electrically connected to the uniform control module of the drive structure; wherein, the brightness sensors are adapted to transmit electrical signals to the control module, and the control module causes the drive structure to roll up or unroll the pull rope.

[0010] Secondly, this disclosure also provides a hollow venetian blind with an intelligent dimming mechanism, comprising: a hollow glass frame with a hidden groove on the inner surface of its bottom; a venetian blind assembly, which is installed inside the hollow glass frame by a pull cord, and a hanging strip is provided at the bottom of the pull cord below the venetian blind assembly; the venetian blind assembly includes: a plurality of venetian slats, the surface of which is provided with protrusions and concave portions; wherein, when adjacent venetian slats are closed, the protrusion of the lower venetian slat is adapted to be fitted into the concave portion of the upper venetian slat; the protrusion includes a magnetic strip, the surface of which is covered with a rubber layer; and the thickness of the rubber layer is 1 / 4 to 1 / 2 of the thickness of the magnetic strip; the surface of the concave portion is coated with magnetic metal powder.

[0014] The beneficial effects of this utility model are that it provides a hollow venetian blind with an intelligent dimming mechanism.

[0025] Research has revealed the following drawbacks of existing technologies: In existing insulated louvered glass with intelligent dimming mechanisms, the curved blades are designed to allow light to pass through when closed. When the curved blades are flipped closed, adjacent blades can only achieve line or point contact, failing to form a continuous contact surface. This contact method inevitably leaves light-transmitting gaps between the blades, with the width of these gaps reaching 0.5-2mm, resulting in a maximum light-blocking rate of only 85-90%. Furthermore, the internal environment of insulated glass is not constant; temperature changes cause the blades to expand and contract. In high-temperature summer environments, aluminum-magnesium alloy blades can expand 0.3-0.5% in length. This slight deformation is sufficient to disrupt the original contact relationship and increase the light-transmitting gaps.

[0026] Therefore, how to avoid light-transmitting gaps when the curved blades are closed is a technical problem that urgently needs to be solved in this field.

[0027] The shortcomings of the above solutions are the result of the utility model inventor's practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as contributions made by the utility model inventor to this disclosure.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0030] like Figures 1 to 5 As shown, some embodiments provide a hollow venetian blind with an intelligent dimming mechanism, including: a hollow glass frame 1, with a drive structure 3 located near the top inside; and a venetian blind assembly 2, which is installed inside the hollow glass frame 1 via a pull cord 4. The drive structure 3 raises, lowers, or rotates the venetian blind assembly 2 by retracting the pull cord 4. Specifically, it mainly includes three parts: the hollow glass frame 1, the venetian blind assembly 2, and the intelligent drive control system. The hollow glass frame 1 adopts a 5+19A+5 double-layer tempered glass structure with a total thickness of 30mm, and the profile groove needs to be configured with a diameter of 33mm or more. A magnetic drive structure 3 is located near the top inside the glass frame. This structure is made of rare earth permanent magnet material and wrapped with an anti-oxidation rubber layer. It achieves non-penetrating transmission through the principle of magnetic coupling.

[0031] The Venetian blind assembly 2 includes several slats 21, each with protrusions 22 and recesses 23 on its surface. When adjacent slats 21 are closed, the protrusions 22 of the lower slats 21 are fitted into the recesses 23 of the upper slats 21 to ensure a tight seal and prevent light from passing through gaps when closed. It should be further noted that the Venetian blind assembly 2 is suspended within the hollow glass frame 1 by a high-strength polymer pull cord 4, and the drive structure 3 uses the retractable pull cord 4 to raise, lower, and rotate the Venetian blind 180 degrees. The Venetian blind assembly 2 consists of 90 aluminum alloy slats 21 per meter in height, with a slat width of 12.5 mm and a thickness of 0.20 ± 0.02 mm. The surface is anodized to a silver-white color.

[0032] The protrusion 22 is disposed on one side of the top edge of the louver 21, and the recess 23 is disposed on the other side of the bottom of the louver 21; the protrusion 22 includes a magnetic strip 25, the surface of which is covered with a rubber skin layer 24; and the thickness of the rubber skin layer 24 is 1 / 4 to 1 / 2 of the thickness of the magnetic strip 25; the surface of the recess 23 is coated with magnetic metal powder.

[0033] Each louver 21 has a protrusion 22 on one side of its top edge and a corresponding recess 23 on the other side of its bottom edge. The protrusion 22 has a built-in neodymium iron boron magnetic strip 25 and is covered with a silicone rubber skin 24 with a thickness of 0.05 mm (the magnetic strip is 0.2 mm thick and the rubber skin is 1 / 4 the thickness of the magnetic strip); the inner surface of the recess 23 is coated with an iron-cobalt-nickel magnetic metal powder coating.

[0034] When adjacent louvers 21 are closed, the protrusion 22 of the lower louver 21 precisely engages with the concave portion 23 of the upper louver 21, creating a triple sealing effect: first, the physical contact between the rubber layer 24 and the concave portion 23; second, the magnetic attraction between the magnetic strip 25 and the magnetic metal powder; and third, the mechanical interlocking of the convex and concave structures. This design allows the louvers to achieve an extremely low shading coefficient of Sc=0.18 when closed, effectively blocking strong direct sunlight in summer.

[0035] Brightness sensors 6 are evenly distributed on both sides of the inner wall of the hollow glass frame 1, and are electrically connected to the uniform control module of the drive structure 3; wherein, the brightness sensor 6 is adapted to transmit electrical signals to the control module, and the control module causes the drive structure 3 to roll up or unroll the pull rope 4.

[0036] Some embodiments provide a hollow venetian blind with an intelligent dimming mechanism, including: a hollow glass frame 1, the inner surface of which has a hidden groove 11; a venetian blind assembly 2, which is set in the hollow glass frame 1 by a pull cord 4, and a hanging strip 5 is provided at the bottom of the pull cord 4 below the venetian blind assembly 2; the venetian blind assembly 2 includes: a plurality of venetian slats 21, the surface of which is provided with protrusions 22 and recesses 23; wherein, when adjacent venetian slats 21 are closed, the protrusions 22 of the lower venetian slats 21 are adapted to be fitted into the recesses 23 of the upper venetian slats 21.

[0037] A protrusion 22 is disposed on one side of the top edge of the louver 21, and a recess 23 is disposed on the other side of the bottom of the louver 21. The protrusion 22 includes a magnetic strip 25, the surface of which is covered with a rubber layer 24; and the thickness of the rubber layer 24 is 1 / 4 to 1 / 2 of the thickness of the magnetic strip 25; the surface of the recess 23 is coated with magnetic metal powder.

[0038] A drive structure 3 is located near the top of the hollow glass frame 1, which raises, lowers, or rotates the venetian blind assembly 2 via a winding pull cord 4. Brightness sensors 6 are evenly distributed on both sides of the inner wall of the hollow glass frame 1, and are electrically connected to the control module of the drive structure 3. The brightness sensors 6 transmit electrical signals to the control module, which then causes the drive structure 3 to wind up or unwind the pull cord 4. High-precision brightness sensors 6, using photoresistor elements, are evenly distributed on both sides of the inner wall of the hollow glass frame 1, with a detection range of 0-20000 lux and an accuracy of ±3%. The brightness sensors 6 are electrically connected to the control module of the drive structure 3, which uses an STM32 series microcontroller and has four preset intelligent modes. The drive structure 3 uses a micro stepper motor, enabling 0.1° angle adjustment accuracy for the venetian blinds. The motor has a built-in temperature sensor and overload protection; it automatically stops and alarms when abnormal resistance is detected. The pull cord 4 is woven from ultra-high molecular weight polyethylene fiber, with a diameter of 0.8mm and a breaking tensile strength of 200N, ensuring no deformation during long-term use.

[0039] In summary, when adjacent louvers 21 are closed, the protrusion 22 of the lower louver 21 precisely engages with the concave portion 23 of the upper louver 21, forming a triple sealing effect: first, the physical adhesion between the rubber layer 24 and the concave portion 23; second, the magnetic attraction between the magnetic strip 25 and the magnetic metal powder; and third, the mechanical interlocking of the convex and concave structures. This design allows the louvers to achieve an extremely low shading coefficient of Sc=0.18 when closed, effectively blocking strong direct sunlight in summer. In addition, a hidden groove 11 is provided on the inner surface of the bottom of the hollow glass frame 1, which works in conjunction with the suspension strip 5 to prevent light transmission at the bottom when closed, further preventing light transmission and enhancing this effect.
