Description

Technical Field

[0001] This invention relates to the field of building door and window technology, specifically to a foldable multifunctional exterior window. Background Technology

[0002] In the field of building door and window technology, exterior windows, as an important component of building envelope, not only undertake the basic functions of lighting and ventilation, but also need to take into account multiple requirements such as sun shading, heat preservation, sound insulation and structural stability.

[0003] As people's requirements for living comfort and building energy conservation increase, composite windows that combine lighting, ventilation and sun shading functions are gradually becoming a research and development hotspot in the industry.

[0004] However, most traditional exterior windows on the market are single-function designs, with the main window frame and shading structure operating independently. Most ordinary exterior windows only have fixed glass or operable glass panes, lacking integrated shading components. To achieve shading, additional accessories such as external awnings and curtains must be installed. These external shading structures are not only cumbersome to install and occupy outdoor space, but also have poor compatibility with exterior windows, making them susceptible to damage from wind, rain, and other environmental factors. Furthermore, they negatively impact the aesthetics of the building facade, failing to meet the demands of modern architecture for integrated, multi-functional windows and doors. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a foldable multifunctional exterior window, which solves the problem that most ordinary exterior windows are only equipped with fixed glass or openable glass panes and lack integrated sunshade components. If sunshade functions are required, additional accessories such as external sunshades and sunshade curtains need to be installed.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a foldable multifunctional exterior window, including a main frame, a main window hinge is fixedly connected to the bottom end of the inner side wall of the main frame, a main window body is fixedly connected to the hinge end of the main window hinge, and sunshades are foldable and unfoldable on both the upper and lower sides of the main window body through multi-angle opening and closing hinge components. Multi-angle opening and closing hinge assembly is used to enable the sunshade to unfold at multiple angles to achieve window opening and closing, ventilation, sun shading, and sunlight exposure.

[0007] Preferably, the multi-angle opening and closing hinge assembly includes a slide rail a, a fixing block fixedly connected to the inner sidewall of the slide rail a, a short connecting rod hinged to one end surface of the fixing block, a connecting rod a hinged to the other end surface of the fixing block, a guide bracket hinged to the end of the short connecting rod away from the fixing block, a connecting rod b slidably connected through the inner sidewall of the connecting rod a, a slider slidably connected to the inner sidewall of the slide rail a, a long connecting rod a hinged to the surface of the slider, and a long connecting rod b slidably connected to the end of the long connecting rod a away from the slider.

[0008] Preferably, the upper surface of the main window is provided with a guide groove, and the lower surface of the slide rail a is fixedly connected with a T-shaped slider, which is slidably connected to the inner wall of the guide groove of the main window.

[0009] Preferably, the sliding of the guide bracket and the sunshade has friction, and the sliding of the T-shaped slider and the inner wall of the main window guide groove has friction.

[0010] Preferably, the end of the long connecting rod b away from the long connecting rod a is hinged to the upper surface of the guide bracket, and the end of the connecting rod b away from the connecting rod a is hinged to the lower surface of the long connecting rod b.

[0011] Preferably, the sidewalls at both the upper and lower ends of the sunshade are provided with guide grooves, and the guide bracket is slidably connected to the surface of the guide grooves of the sunshade.

[0012] Preferably, the guide bracket can rotate less than 180 degrees around the hinge point of the short connecting rod.

[0013] Working principle: 1. Main window closed, sunshade open: Allow sunlight to enter. First, the main window is rotated to the closed position via the main window hinge (corrosion-resistant stainless steel hinge), ensuring the main window (double-layered tempered glass structure) is sealed against the main frame, thus completing the window closing action. Then, the sunshade is opened by adjusting the multi-angle opening and closing hinge assembly. The specific linkage process is as follows: The T-shaped slider on the lower surface of slide rail a slides along the guide groove on the upper surface of the main window (the two slide with friction, allowing for stable stopping). Slide rail a moves synchronously, causing displacement of components such as the fixed block and slider. The fixed block drives the short connecting rod to move synchronously with connecting rod a. The short connecting rod drives the guide bracket (U-shaped groove structure) to rotate around the hinge point (rotation range 0-170 degrees, less than 180 degrees). Simultaneously, connecting rod a pulls connecting rod b to slide, and connecting rod b further drives the long connecting rod b. This, combined with the sliding connection between the long connecting rod a and long connecting rod b hinged to the slider, forms a multi-link linkage support. As the guide bracket rotates, it slides along the guide grooves at both ends of the sunshade (the sliding between the two creates friction), ultimately pushing the sunshade to an open position away from the main window. The angle is fixed by the damping effect of each friction pair. At this time, the closed main window allows sunlight to pass through, while the open sunshade does not block the light path, thus achieving the function of sunlight exposure when the main window is closed.

[0014] 2. Main window closed, sunshade closed: Achieve sunshade With the main window closed, the sunshade is driven to close by reverse adjustment of the multi-angle opening and closing hinge assembly. During operation, the T-shaped slider of slide rail a is pulled in the opposite direction, causing it to move back along the main window's guide groove, thus resetting slide rail a. Simultaneously, the fixed block moves in the opposite direction, the short connecting rod pulls the guide bracket to rotate in the opposite direction, connecting rod a pushes connecting rod b back, and the long connecting rods a and b retract together, causing the guide bracket to slide in the opposite direction along the sunshade's guide groove, pulling the sunshade to the closed position against the outside of the main window. The friction between the T-shaped slider and the main window's guide groove, and between the guide bracket and the sunshade's guide groove, keeps the sunshade stably closed. At this time, the closed main window, combined with the sunshade (lightweight, corrosion-resistant aluminum alloy sheet with a sun-protective coating) against its surface, effectively blocks direct sunlight, achieving a sunshade function. Meanwhile, the double-layered hollow structure of the main window still maintains indoor thermal insulation and soundproofing effects.

[0015] 3. Open the main window and open the sunshade: to achieve ventilation and sun shading. First, rotate and open the main window using the main window hinges to put it in an open, ventilated state (the main window hinges can open and close in both directions with controllable angles, making it easy to fix the opening angle). Then, following the above-described operation logic for opening the sunshade, adjust the multi-angle opening and closing hinge assembly: push the T-shaped slider to slide along the guide groove of the main window, drive the guide bracket to rotate through the multi-link linkage structure, and drive the sunshade to unfold. Use the damping of each friction pair to fix the unfolding angle and position of the sunshade, so that the sunshade is located on the outside of the open main window, forming a sunshade. At this time, the open main window provides a ventilation channel for the room, and air can circulate through the gap between the main window and the main frame; the unfolded sunshade can block direct sunlight, preventing strong light from entering the room, while not obstructing the ventilation path, thus achieving a balance between ventilation and sunshade functions.

[0016] IV. Main window open, sunshade closed: to allow ventilation and sunlight exposure. Keep the main window open via its hinges to ensure unobstructed indoor ventilation. Then, adjust the multi-angle hinge assembly to close the sunshade. This involves pulling the T-slider in the opposite direction, which, through multi-link linkage, pulls the sunshade to the closed position against the outside of the main window and secures it with the help of friction structures. At this point, the closed sunshade will not obstruct the ventilation area of ​​the open main window, nor will it block sunlight. Sunlight can penetrate the open main window area and enter the room, while air circulates freely through the opening gaps in the main window, ultimately achieving simultaneous ventilation and sunlight access.

[0017] In summary, the multi-link linkage structure and friction positioning design of the multi-angle opening and closing hinge assembly are the core of achieving the switching of four working conditions. Combined with the opening and closing adjustment of the main window hinge, the exterior window has multiple functions such as lighting, sun shading, and ventilation, and the switching of each working condition is smooth and the positioning is stable.

[0018] This invention provides a foldable, multi-functional exterior window. It has the following beneficial effects: 1. The multi-link linkage structure design of the multi-angle opening and closing hinge assembly of this invention significantly optimizes the flexibility and adaptability of switching window operating conditions, effectively improving the shortcomings of existing composite window sunshade angle adjustment and poor linkage stability. Through the coordinated linkage of short links, long links, slide rails, sliders, and guide brackets, combined with a friction positioning mechanism, the sunshade can be precisely opened and fixed at multiple angles, flexibly adapting to the angle of sunlight at different times and seasons. It easily switches between four combined operating conditions of the main window and the sunshade, enabling sunlight exposure or shading when the main window is closed, and balancing ventilation and shading, or ventilation and lighting needs when the main window is open.

[0019] 2. In the multi-angle opening and closing hinge assembly of this invention, the friction coefficients between the T-shaped slider and the main window guide groove, and between the guide bracket and the sunshade guide groove, are precisely controllable. This avoids excessive friction leading to difficult adjustments, while also enabling stable positioning of the sunshade at any angle through moderate friction, preventing displacement due to external forces and improving operational stability. Simultaneously, the multi-link linkage structure replaces the single-link or slide rail drive mode, making the opening and closing of the sunshade smoother. Combined with the bidirectional opening and closing adjustment of the main window hinge, it achieves coordinated adaptation of the actions of each component.

[0020] 3. This invention integrates the sunshade with the main frame and main window body through a multi-angle opening and closing hinge assembly, eliminating the need for additional external components. This not only simplifies the installation process and saves outdoor space but also allows it to blend naturally with the building facade, enhancing the overall aesthetics. Furthermore, the sunshade is made of lightweight, corrosion-resistant aluminum alloy with a sun-protective coating. Combined with its integrated structural design, it offers stronger resistance to wind, rain, and other environmental erosion, significantly extending its service life and perfectly meeting the modern architectural demand for integrated, multi-functional doors and windows.
