Description

Technical Field

[0001] The invention relates to the technical field of building sunshade, in particular to a combined multi-layer retractable curtain sunshade device installed on a building window and a glass curtain wall, which is beneficial to vision, lighting and intelligence. Background Art

[0002] Building windows have basic functions such as vision, lighting, and ventilation. The sunlight radiation through them is the fundamental source of indoor heating. In hot summer, necessary building shading measures are taken to reduce and lower the impact and harm of sunlight on the building environment and people; especially in hot summer areas, building shading has a very significant effect on reducing energy consumption and improving living comfort. Therefore, building shading is crucial to the natural adaptability and functionality of buildings. At present, building windows and glass curtain walls mainly adopt sunshades, awnings, sunshades, blinds, blackout curtains and glass filters to shade the sun. Fixed structural sunshades and awnings are single component devices with large size and volume. They are limited by the building's environmental space and the facade. Regardless of seasonal changes and whether they are shaded or not, the absolute value of the obstruction of vision and lighting is the same. The blade width of blinds and venetian blinds is fixed, and the blade spacing is also relatively dense, so the vision and light are also largely blocked. Blackout curtains and sunshade gauze basically block all vision and light. Glass self-shading changes the natural color of indoor light by filtering and reflecting sunlight, causing indoor environmental color distortion and ventilation cannot be opened when shading. These shading devices and components, whether fixed or adjustable, have prominent contradictions between shading and the vision and lighting functions of windows and glass curtain walls due to the fixed position, size and width of the shading components and devices. If the shading of windows and walls is fully satisfied, it is difficult to take into account their basic functions of vision and lighting, and it is difficult to use natural changes to improve vision, field of view and illumination. In fact, the better the shading effect, the worse the vision and lighting. The automation and intelligent development of the visual, lighting and ventilation functions of the building environment has therefore become unsustainable.

[0003] Based on the above problems, in order to balance the basic functions of building windows and glass curtain walls, the present invention proposes a multi-layer retractable curtain combined shading device with elastically variable size and volume of shading component devices, which takes into account the most basic functions of vision and lighting of building windows and glass curtain walls by utilizing existing technologies, materials, automation, intelligence and other conditions. The shape and volume of this multi-layer retractable and angle-adjustable shading device can be retracted and changed with the season, climate, solar altitude angle and azimuth, which greatly reduces the interference and influence of shading components and devices on the field of vision and lighting of windows and glass curtain walls, improves the flexibility of the shading system, and is beneficial to the balance of building functions and the intelligent operation of the device. Summary of the invention

[0004] The key retractable curtain sunshade component in the device of the present invention is composed of a sunshade curtain, a rolling curtain rod and a parallel pulling rod. The sunshade curtain is rolled up on the rolling curtain rod. The two ends of the rolling curtain rod are built-in with spiral springs and fixed (rotatably) installed in the outer frame of the sunshade unit device structure. The pulling rod can pull the sunshade curtain to be extended from the rolling curtain rod, and the sunshade curtain is subjected to the rebound tension of the rolling curtain rod spring; multiple retractable curtain sunshade components are installed in layers on the outer frame of the device structure, and the spacing of each layer of the components is determined according to the visual distance between the human eye and the window and the glass curtain wall and the static vertical viewing angle; the two ends of the pulling rod of each layer are respectively connected to two tension rods with equidistant rotating pins, and the two ends of the tension rods are respectively connected to the brackets extending from the four corners of the device structure outer frame, and the device structure outer frame and the bracket have built-in drive motors, transmission rods, and screws to drive the tension rods to move on the externally protruding brackets, and synchronously pull the sunshade curtain to retract and tilt.

[0005] The essence of the present invention is to combine large-volume sunshades, awnings and dense, narrow blinds, improve the adverse effects of the former's single component and device volume on the building's external space and appearance, and increase the blade spacing of the latter to meet the static viewing angle in front of the window, so as to achieve maximum direct vision from indoor to outdoor. It is important that the sunshade curtain of the sunshade unit can be horizontally retracted, staggered and tilted in multiple layers synchronously. This technical measure of variable width and adjustable angle enables the device to be adjusted according to the regular changes of the sun's altitude angle when shading, improves the balance and optimization of the sunshade, vision, lighting and ventilation functions of windows and glass curtain walls, and the parameters of the sunshade curtain extension and retraction are more conducive to the data control of the sunshade system.

DETAILED DESCRIPTION

[0017] The present invention is further described in detail below in conjunction with an example of sunshading for north-south exterior windows of a building and accompanying drawings. However, the implementation methods of the invention are not limited thereto due to changes in the orientation of the building and the location of the sunshade.

[0018] A horizontal sunshade curtain 5 is embedded and connected with the inner roller blind rod 1 and the outer horizontal pull rod 3. The roller blind rod 1 can roll up and roll down the sunshade curtain 5, thus forming a retractable curtain sunshade component. A rectangular sunshade device structural frame 6 is a structural member for connecting and fixing the sunshade device unit to the building exterior wall, and can also be a window frame and curtain wall structural member to support the structure of the entire device. Multiple retractable curtain sunshade components are installed at equal intervals and in layers. The horizontal full-length rolling curtain rod 1 is connected to the vertical frame of the device structure outer frame 6 through a fixed connecting part 2 that allows the rolling curtain rod 1 to rotate. The fixed connecting part 2 has a built-in return spiral spring 13 to provide return force when it is rolled; the two ends of the pulling straight rod 3 are connected to the tension straight rod 7 by a connecting screw pin 8, and the two ends of the vertical tension straight rod 7 are respectively connected to the upper and lower cantilevered brackets 9. A transmission rod driving motor 12 is arranged in the device structure outer frame 6 to drive the transmission rod 10, which can push the tension straight rod 7 to move horizontally along the cantilevered bracket 9; a screw rod 4 is arranged in the upper end part of the tension straight rod 7, and a screw driving motor 11 is arranged at the top of the screw 4 to drive the rotation. The transmission rod driving motor 12 drives the tension rod 7 to move outward, and the horizontal pulling rod 3 on one side of the sunshade curtain 5 moves accordingly, and the pulling rod 3 pulls the sunshade curtain 5 to drive the rolling curtain rod 1 to rotate, and the sunshade curtain 5 is unfolded, and the rebound force of the fixed connecting part 2 allows the unfolded sunshade curtain 5 to always maintain the retracted tension; the transmission rod 10 then drives the tension rod 7 back, and the rolling curtain rod 1 is reversed by the rebound force of the fixed connecting part 2 to roll up and recycle the sunshade curtain 5, and the rolling and stretching of the sunshade curtain 5 makes it wider. The width can be extended and retracted; the motor 11 drives the screw rod 4 to rotate and push the tension rod 7 to move up and down, driving the pulling rod 3 and the outer end of the sunshade curtain 5 to move to tilt the sunshade curtain 5, and the offset height difference between the pulling rod 3 and the rolling curtain rod 1 produces an inclination angle of the sunshade curtain 5; the tension rod 7 together with the pulling rod 3 can be retracted to close to the outer frame 6 of the device structure, and the screw drive motor 11 drives the screw 4 to push the tension rod 7 together with the pulling rod 3 downward, driving the sunshade curtain 5 to extend downward to cover the window.
